Description

Technical Field

[0001] This utility model belongs to the field of terminal crimping technology, and in particular relates to an automatic PCB terminal crimping machine. Background Technology

[0002] A PCB (Printed Circuit Board) terminal crimping machine is a device specifically designed for crimping terminals and wires onto PCB boards. It achieves electrical connection by firmly crimping the terminals to the wire ends of cables and is widely used in the electronics manufacturing industry.

[0003] Currently, the crimping process for PCB board terminals and cables still suffers from limitations due to manual operation. Specifically, operators must first manually place the terminal blocks onto the positioning blocks, then manually insert each cable into the terminal block to ensure a tight fit. Finally, a crimping machine is used to crimp the placed terminals and cables. This heavily manual process not only reduces overall production efficiency but also increases labor costs and intensity. Utility Model Content

[0004] The purpose of this invention is to address the current practice where operators must manually place the terminal blocks onto the positioning blocks, then manually insert the cables one by one into the terminal blocks to ensure a tight fit, and finally use a crimping machine to crimp the placed terminal blocks and cables. This highly manual process not only reduces overall production efficiency but also increases labor costs and intensity. Therefore, this invention proposes an automatic PCB terminal crimping machine.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic PCB terminal crimping machine, comprising:

[0006] A workbench, on which a support frame is provided, and on which a telescopic cylinder and several limiting bodies are provided;

[0007] The pressing structure includes a moving block, a forming block, and a positioning block. The moving block is connected to the telescopic cylinder, the positioning block is located on the worktable, the forming block is connected to the moving block, and the moving block is slidably connected between a plurality of the limiting bodies.

[0008] and several transmission structures located on the end side of the terminal block.

[0009] As a further description of the above technical solution:

[0010] The terminal block has a slot, and the cable is placed in the slot.

[0011] As a further description of the above technical solution:

[0012] The limiting body is provided with a conveying groove, and a positioning element is provided on the wall of the conveying groove located on one side of the limiting body. The terminal strip is provided with a plurality of conveying holes, and the positioning element moves the conveying holes to convey it forward.

[0013] As a further description of the above technical solution:

[0014] The positioning component includes a miniature cylinder and a positioning claw. The miniature cylinder is connected to the wall of the conveying groove, and the positioning claw is connected to the miniature cylinder. The positioning claw abuts against the terminal block.

[0015] As a further description of the above technical solution:

[0016] The terminal block is provided with mounting blocks on both sides. The transmission structure is connected to the mounting blocks. The transmission structure includes a connecting plate, a micro motor and a transmission body. The connecting plate is connected to the mounting blocks. The micro motor passes through the connecting plate and is connected to the transmission body. The transmission body is provided with a push pin on its periphery. The push pin moves the transmission hole.

[0017] As a further description of the above technical solution:

[0018] The molding block is provided with a molding groove, and a cutting blade is provided on the inner wall of the molding groove.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] In this invention, a conveying structure is used to place the entire terminal block on a positioning block. The terminal block has several conveying holes. A micro motor in the conveying structure drives the conveyor to rotate, which in turn drives the pins on the conveyor to rotate and move the conveying holes, thus pushing the terminal block forward at equal distances. When the terminal block on the front side is at the bottom of the crimping structure, the positioning component on the front side, driven by a micro cylinder, abuts the two sides of the positioning claw against the horizontal abutment plates on both sides of the terminal block. The bottom of the positioning claw abuts the top of the terminal block, thus limiting the terminal block. The cable is then placed into the slot. The forming block in the crimping structure presses onto the terminal block, and the cutting blade on the forming block cuts the crimped terminal block, thus completing the crimping of a section of terminal block and cable. This structure automates the crimping of terminal blocks and cables, improving production efficiency and reducing labor costs. Attached Figure Description
