Advanced soldering paste manufacturing equipment featuring improved pressing mechanisms
Key Components of the Innovative Pressing System
The improved soldering paste manufacturing equipment incorporates several key components designed to enhance performance and safety. Understanding these components helps clarify what is soldering paste's production process and how modern techniques overcome traditional limitations.
Preparation Housing
The main structure, known as the preparation housing (100), contains all the critical components of the pressing system. Its robust design ensures stability during operation while protecting internal mechanisms.
Placement Cavity
Located in the bottom end face of the preparation housing, the placement cavity (122) provides the workspace where the soldering paste container is positioned for the pressing operation.
Adjustment Slot and Seat
An adjustment slot (102) in the top wall of the placement cavity contains a sliding adjustment seat (101) that controls the vertical position of the pressing mechanism.
Pressing Column and Plate
A pressing column (143) slides within the first sliding cavity (141) of the adjustment seat, extending into the placement cavity. At its bottom end, a pressing plate (142) makes direct contact with the soldering paste container.
Guide Slots and Blocks
Symmetrically arranged guide slots (137) with sliding guide blocks (136) ensure stable vertical movement of the pressing column, preventing lateral displacement during operation.
First Elastic Strips
Positioned in the guide slots beneath the guide blocks, these elastic components (144) provide the necessary upward force for the reciprocating motion of the pressing mechanism.
Hydraulic Pressure System
A key innovation in understanding what is soldering paste's modern production is the integrated hydraulic pressure system that provides precise control over the pressing force:
| Component | Function |
|---|---|
| Pressure Cavity (132) | Houses the hydraulic components and fluid, creating a closed system for pressure transmission |
| First Piston Block (133) | Connected to the pressing column, converts hydraulic pressure into linear motion |
| Second Piston Block (148) | Receives mechanical input and transfers pressure through the hydraulic fluid |
| Hydraulic Fluid (131) | Transmits pressure between piston blocks with minimal energy loss |
| First Restriction Plates (147) | Limit movement of the second piston block, ensuring safe and controlled operation |
Drive Mechanism
The drive mechanism converts rotational motion into the reciprocating action needed for pressing. A first drive motor (128) powers a first bevel gear (127) that engages with a second bevel gear (124) mounted on a rotating arm (125).
As the rotating arm turns, a cam (123) at its end repeatedly presses against the second piston block, creating the hydraulic pressure that drives the pressing plate. This innovative design ensures consistent, controlled pressure application critical for producing high-quality soldering paste.
Transmission and Control Systems
Modern soldering paste manufacturing equipment incorporates sophisticated transmission and control systems that enhance precision, safety, and efficiency. These systems represent significant advancements in addressing what is soldering paste production needs in contemporary manufacturing environments.
Transmission Chamber Components
Screw Rod (104)
Connects to the adjustment seat via threaded engagement, converting rotational motion into vertical movement
Bevel Gear System
Includes third, fourth, and fifth bevel gears (103, 107, 109) for efficient power transmission and direction change
Second Drive Motor (111)
Provides power for adjusting the vertical position of the adjustment seat and pressing mechanism
Pneumatic Control System
An air cylinder (105) with a piston rod (106) controls the engagement and disengagement of the gear system. This allows for precise control over when power is transmitted to the screw rod, enhancing operational safety and efficiency.
When engaged, the system drives the adjustment seat down into the operating position. When disengaged, it allows for safe maintenance and prevents accidental operation, addressing a major safety concern of traditional equipment.
Safety and Locking Mechanisms
Understanding what is soldering paste production safety involves examining the innovative locking mechanisms that prevent accidents and ensure stable operation:
Slope Sliding Block and Locking System
A slope sliding block (112) in the third sliding cavity (118) works with locking blocks (117) in the fourth sliding cavities (116) to secure the adjustment seat in position. This system operates automatically as the pneumatic cylinder engages or disengages the gear system.
Second elastic strips (115) provide the force to move the locking blocks into position, engaging with either the first locking groove (113) or second locking groove (134) depending on the adjustment seat's position.
Operating Position Safety
When the adjustment seat is in the lower operating position, the locking blocks engage with the second locking groove, securing the mechanism during the pressing operation. This prevents unwanted movement that could affect product quality or create safety hazards.
Storage Position Safety
In the raised storage position, the locking blocks engage with the first locking groove, securing the mechanism during transportation or when not in use. This prevents damage from vibration and movement, extending equipment lifespan.
Sensors and Automatic Control
The equipment incorporates an induction device mounted in the top wall of the placement cavity, consisting of a position sensor (201) with a protective housing (202). This sensor system provides precise position detection for automated control of the equipment.
What is soldering paste production automation without such sensors? These components enable the system to automatically detect the presence of materials, ensure proper positioning, and prevent collisions between components.
The sensor data feeds into the equipment's control system, enabling features like automatic shutdown when anomalies are detected, further enhancing operational safety and product quality consistency.
Operational Process
Understanding what is soldering paste manufacturing requires familiarity with the precise operational process of modern pressing equipment. The following steps outline the complete cycle from initial setup to active pressing and back to storage configuration.
Initial State Configuration
In its resting configuration, the adjustment seat is positioned at the top of the adjustment slot, with the pressing plate fully contained within the placement cavity. This compact arrangement facilitates easy movement and storage of the equipment.
Safety systems are engaged: the first bevel gear is disengaged from the second bevel gear, and the fourth bevel gear is disconnected from both the third and fifth bevel gears. The locking block is fully extended into the first locking groove, securing the adjustment seat.
System Activation
To begin the pressing operation, the air cylinder is activated, extending the piston rod and lowering the fourth bevel gear into engagement with both the third and fifth bevel gears. This connects the drive system to the screw rod.
Simultaneously, the fourth bevel gear drives the slope sliding block downward, which pushes the locking block to the right against the force of the second elastic strip, completely exiting the first locking groove and unlocking the adjustment seat.
Adjustment Seat Lowering
With the system engaged and unlocked, the second drive motor is activated, rotating the screw rod through the gear system. This rotation drives the adjustment seat downward along the adjustment slot.
The descent continues until the top wall of the recessed portion contacts the top end face of the second restriction plate, establishing the operating position. At this point, the first bevel gear engages with the second bevel gear, and the cam comes into contact with the second piston block.
Securing Operating Position
Once in the operating position, the air cylinder is reversed, retracting the piston rod and allowing the slope sliding block to move upward. Under the force of the second elastic strip, the locking block automatically slides into the second locking groove, securing the adjustment seat in its operating position.
This locking mechanism ensures stability during the pressing operation, preventing movement that could affect the consistency and quality of what is soldering paste's final properties.
Pressing Operation
With the system properly positioned and secured, the first drive motor is activated. This drives the rotation of the cam through the bevel gear and rotating arm assembly, causing the cam to reciprocally press against the second piston block.
The second piston block transfers this pressure through the hydraulic fluid, pushing the first piston block downward. This movement is transmitted to the pressing column and pressing plate, which descend to compress the soldering paste.
The upward force of the first elastic strip causes the pressing plate to reciprocate, creating the repeated pressing action needed to ensure the soldering paste's uniformity and stability.
Completion and Reset
Upon completion of the pressing cycle, the system reverses the process: the air cylinder activates to disengage the gears and unlock the adjustment seat, the second drive motor reverses to raise the adjustment seat, and the air cylinder retracts to lock the seat in its upper position.
The pressing plate is fully retracted into the placement cavity, and all drive systems are disengaged, returning the equipment to its initial safe and compact configuration for storage or transportation.
