Technical Field

[0001] The utility model relates to the field of jigs, in particular to a circuit board tooling jig. Background Art

[0002] There are some common problems with existing welding jigs. Their structures are often relatively complex, which not only increases the difficulty of use, but also may affect the overall efficiency of welding work. More importantly, some jigs are not ideal in fixing circuit boards and cannot ensure the stability and accuracy of circuit boards during welding. At the same time, the operation steps for installing and disassembling circuit boards are also relatively cumbersome, which undoubtedly further reduces the efficiency of welding jigs.

[0003] In order to overcome the shortcomings of the existing clamping device, we propose a simple, reliable and easy-to-use circuit board tooling fixture.

[0004] Therefore, it is necessary to provide a circuit board fixture to solve the above technical problems. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1 to Figure 2 A circuit board fixture is mainly composed of a carrier plate 1, and a receiving groove 2 is specially built on the top of the carrier plate, which is specially used to stably place the circuit board. Inside the receiving groove 2, an electronic device installation groove 3 is carefully set up to pre-place the electronic devices to be soldered and ensure that the pins of these devices face upward so that they can smoothly pass through the corresponding holes on the circuit board.

[0018] On the carrier plate 1, the first rotating shafts 4 are cleverly connected to the four sides of the receiving slots 2. Springs 5 ​​are firmly fixed to the first rotating shafts 4, and their main function is to press the circuit board when needed. At the same time, on the carrier plate 1, the four corners of the receiving slots 2 are also connected to the second rotating shafts 6. Gears 7 are fixed to the other ends of the first rotating shafts 4 and the second rotating shafts 6, and the gears 7 are cleverly connected to each other through gear belts 8. What is more clever is that a driving arm 9 is fixed to one of the second rotating shafts 6, which can easily drive the second rotating shaft 6 to start rotating.

[0019] When you need to fix the circuit board in the receiving slot 2 for subsequent welding work, you only need to simply place the electronic components to be welded in the electronic component mounting slot 3 and make sure that their pins are facing upward. Then, place the circuit board in the receiving slot 2, and let the pins of the electronic components accurately pass through the holes on the circuit board. Next, by gently turning the drive arm 9, one of the second rotating shafts 6 can be driven to start rotating. This rotation action will drive all the first rotating shafts 4 to rotate synchronously with the help of the ingenious transmission design of the gear belt 8. As the first rotating shaft 4 rotates, the spring 5 fixed thereon will also rotate accordingly, steadily move to the top of the circuit board, and firmly fix it in the receiving slot 2.

[0020] In order to make it easier and more convenient for you to use this tooling fixture, handles 10 are integrated at both ends of the carrier plate 1, so that you can easily pick it up or move it. At the same time, two limit blocks 11 are specially installed on the top of the carrier plate 1. Their main function is to effectively limit the rotation range of the driving arm 9 and ensure that the rotation angle of the second rotating shaft 6 is always maintained between 0-90 degrees, thereby increasing the stability and safety of the operation.

[0021] In addition, the bottom of the carrier plate 1 has also been carefully designed. The position facing the gear 7 is rotatably connected to the limit column 12, and these limit columns 12 are in close contact with the gear belt 8. This design not only makes the cooperation between the gear belt 8 and the gear 7 more stable and reliable, but also further improves the durability and practicality of the entire tooling fixture.

[0022] Finally, it is worth mentioning that the end of the driving arm 9 is also specially equipped with an anti-slip cover 13. This thoughtful design not only makes you feel more comfortable when holding, but also effectively prevents your hand from sliding, ensuring your stability and safety during operation.

[0023] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
