Technical Field

[0001] This invention belongs to the technical field of circuit board processing equipment, and particularly relates to a circuit board and fixture assembly / disassembly device and a fixture recycling system. Background Technology

[0002] Currently, the processing of circuit boards, such as soldering circuits and insulation treatment, is carried out by directly grabbing the edges of the circuit boards with conveyor belts or robotic arms and transferring them from one process to the next. The disadvantages are: first, the edges of the circuit boards are small, making them difficult to grab and easily damaging the electronic components on the circuit boards; second, the grabbing and conveying process can easily damage or wear down the circuit boards and even damage the electronic components on the circuit boards; and third, it is not easy to form an assembly line operation for circuit board processing.

Four vertical guide holes are provided on the four corners of the base plate and the workbench. The upper ends of the four slide rods are fixed on the lifting platform, and the lower ends pass through the guide holes and are fixed on the positioning plate. The first motor that drives the lifting platform to rise and fall is fixed on the bottom surface of the base plate. A rack arranged parallel to the slide rods passes through the through hole on the base plate and meshes with the gear on the motor shaft of the first motor. The upper end of the rack is fixed on the lifting platform.

[0022] The advantages of this invention compared to the prior art are:

[0023] 1. This invention uses a clamp to hold the edge of a circuit board, forming a circuit board with a clamp. During the process of gripping the circuit board, simply gripping the clamp will cause the circuit board to be gripped along with it. This makes gripping easy and prevents damage to the electronic components on the circuit board during the gripping process, thus providing good protection for the circuit board and its electronic components.

[0024] 2. This invention uses a clamp to hold the circuit board and a transfer clamp to achieve the purpose of transferring the circuit board. During the transfer and processing of the circuit board, it is not easy to damage or wear the circuit board and its electronic components, thus providing a better protection effect for the circuit board and its electronic components.

[0025] 3. Because the circuit board is installed (clamped) in the fixture and transported in various conveying devices such as conveyor belts, the present invention is less likely to damage or wear the circuit board and its electronic components, making it particularly suitable for use in assembly line operations for circuit board processing.

[0026] 4. The present invention connects a circuit board and a fixture assembly / disassembly device to each end of the parallel circuit board processing production line and the fixture return mechanism to form a fixture recycling system, which facilitates the recycling of fixtures, has high fixture utilization efficiency, and saves equipment investment costs.
