Description

Technical Field

[0001] This utility model relates to the field of semiconductor probe pin processing technology, specifically a PTFE sol-gel spraying device for semiconductor probe pin surface. Background Technology

[0002] Air spray guns (pneumatic spray guns) use compressed air to atomize PTFE sol and spray it evenly onto the surface of the substrate. They are suitable for spraying small to medium-sized areas or complex shapes (such as electric knife tips and irregularly shaped metal parts).

[0003] In existing technologies, the spray gun and the gun cup are mostly fixed by threaded connection. This connection structure requires multiple rotations of the gun cup to tighten or separate during installation and disassembly, which is cumbersome, time-consuming, and not very convenient. It may also cause the threads to strip due to uneven force during rotation, affecting the stability of the subsequent connection. Utility Model Content

[0004] The purpose of this invention is to provide a PTFE sol-gel spraying device for the surface of semiconductor probe pins, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PTFE sol-gel spraying device for semiconductor probe pin surfaces, comprising a spray gun and a gun cup, wherein a connection port is fixedly connected to the bottom end of the gun cup, and symmetrically arranged main magnets are fixedly connected to the connection port; a locking mechanism is provided at the top end of the spray gun, the locking mechanism comprising a mounting ring, symmetrically arranged connecting grooves being formed on the mounting ring, a locking groove being formed inside the mounting ring, a rubber pad being fixedly connected to the bottom end of the locking groove, and symmetrically arranged secondary magnets being fixedly connected inside the locking groove.

[0006] Preferably, the bottom end of the connector slides through the mounting ring and connects with the spray gun.

[0007] Preferably, the mounting ring is fixedly connected to the top of the spray gun, and the main magnets are all slidably connected inside the locking groove.

[0008] Preferably, each of the main magnets is magnetically connected to its corresponding secondary magnet.

[0009] Preferably, the rubber pads are all in a compressed state at the positions corresponding to the main magnets.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the locking or disassembly of the spray gun and the gun cup can be completed in only two steps during operation. First, press the gun cup and then rotate it 90°. There is no need to turn it many times throughout the process. The operation is simple and efficient, which greatly improves the ease of use. Especially in scenarios where the gun cup needs to be frequently disassembled for loading and changing materials, it can significantly shorten the operation time and reduce labor costs.

[0011] It avoids the problem of easy stripping of traditional threaded connections, and takes into account both practicality and stability, providing a guarantee for continuous operation of the spray gun. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 The present invention provides the following technical solution:

[0018] A PTFE sol-gel spraying device for semiconductor probe pins includes a spray gun 1 and a gun cup 2. The bottom end of the gun cup 2 is fixedly connected to a connection port 3, and symmetrically arranged main magnets 4 are fixedly connected to the connection port 3. The top end of the spray gun 1 is provided with a locking mechanism 5. The locking mechanism 5 includes a mounting ring 51, symmetrically arranged connecting grooves 52 are opened on the mounting ring 51, a locking groove 53 is opened inside the mounting ring 51, a rubber pad 54 is fixedly connected to the bottom end inside the locking groove 53, and symmetrically arranged auxiliary magnets 55 are fixedly connected inside the locking groove 53.

[0019] The bottom end of the connector 3 slides through the mounting ring 51 and connects with the spray gun 1, so that the spray gun 1 can draw out the molten adhesive inside the gun cup 2 through the connector 3 when it is started. The mounting ring 51 is fixedly connected to the top of the spray gun 1. The main magnets 4 are all slidably connected inside the locking groove 53. The main magnets 4 are all magnetically connected to the corresponding auxiliary magnets 55. The auxiliary magnets 55 can lock the main magnets 4 inside the locking groove 53. The rubber pads 54 are all in a compressed state at the positions corresponding to the main magnets 4.

[0020] In use, add PTFE sol inside the gun cup 2, then hold the gun cup 2 so that the connecting port 3 aligns with the center of the mounting ring 51 and the main magnet 4 aligns with the connecting groove 52. Insert the connecting port 3 into the mounting ring 51, and the main magnet 4 passes through the connecting port 3 into the locking groove 53 inside the mounting ring 51. Then press the gun cup 2 firmly, causing the gun cup 2 to drive the two main magnets 4 to press down forcefully in the locking groove 53 through the connecting port 3. The main magnets 4 will flatten the rubber pad 54 in the locking groove 53. At this time, the main magnets... Only when the top of 4 aligns with the top wall of the locking groove 53 can the gun cup 2 be rotated directly. The gun cup 2 will drive the connection port 3 and the main magnet 4 to rotate. The main magnet 4 will rotate in the locking groove 53 towards the corresponding auxiliary magnet 55. When the main magnet 4 and the auxiliary magnet 55 are magnetically connected, the gun cup 2 is fixed. At the same time, the rubber pad 54 pressed by the main magnet 4 will continuously generate stress, so that the main magnet 4 adds another layer of fixation, achieving the purpose of double fixation. At this time, the spray gun 1 can be used to spray the surface of the semiconductor probe pin by using the wrench of the spray gun 1.
