Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a PCB module potting fixture. Background Technology

[0002] PCB module potting fixtures are a type of special mold used in the electronics manufacturing industry. They are mainly used for precise potting operations on PCB (printed circuit board) modules to achieve purposes such as encapsulation protection, heat dissipation optimization, and structural reinforcement.

[0003] Combined with appendix Figure 1 The existing PCB module structure and packaging process mainly involve the following structural principles and steps:

[0004] S1. The internal printed circuit board is fixed together with the aluminum heat sink base plate by manual soldering of the PIN pins, which is a in the figure;

[0005] S2. The aluminum heat sink base plate and the internal printed circuit board are placed together into the slot of the potting compound fixture (b);

[0006] S3. Pour in an appropriate amount of potting compound;

[0007] S4. Cover with the pentahedral plastic shell (d);

[0008] S5. Remove the module (a) from the potting compound fixture (b) and bake it in the oven to cure the potting compound.

[0009] S6. Finally, remove any excess potting compound from the module surface;

[0010] However, the above packaging process has the following drawbacks:

[0011] (1) After potting, the module as a whole is not easy to remove from the potting fixture;

[0012] (2) After potting, there may be a risk of undried glue leaking when the module is removed from the potting fixture;

[0013] (3) After the module is baked, the excess adhesive on the surface of the aluminum substrate needs to be removed. Utility Model Content

[0014] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a PCB module potting fixture.

[0015] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0016] A PCB module potting fixture includes a base plate with bolt holes at its four corners. Locking bolts are fitted into the bolt holes, and a fixing structure is mounted on the base plate through the bolt holes and the locking bolts.

[0017] The fixing structure includes a left fixing block and a right fixing block. The left fixing block and the right fixing block are provided with through holes that match the position and specifications of the locking bolt. Both sides of the left fixing block and the right fixing block are integrally connected with ear plates. Locking components and disassembly components are installed on the ear plates on the same side of the left fixing block and the right fixing block. PCB modules are filled into the left fixing block and the right fixing block.

[0018] Furthermore, the base plate is provided with a sealing groove, in which a sealing ring is placed. With this design, when the left and right fixing blocks are installed on the base plate, the sealing ring can be compressed to seal the connection position.

[0019] Furthermore, the left fixing block and the right fixing block are provided with a protrusion and a groove opposite to each other, and the gap of the protrusion matches the groove. This design serves to prevent mistaken identity, position the left fixing block and the right fixing block, and enhance the sealing effect.

[0020] Furthermore, the locking assembly includes a through hole on the ear plate, in which a locking screw is installed, and the locking screw is threadedly connected to a nut. This design allows for the fixed connection of the left and right fixing blocks through the locking screw and nut.

[0021] Furthermore, the disassembly assembly includes a disassembly screw threaded to the ear plate of the left fixing block, with the end of the disassembly screw contacting the ear plate of the right fixing block. With this design, after the locking assembly is disassembled, rotating the disassembly screw can push the left fixing block away from the right fixing block, thereby achieving the separation and disassembly of the two.

[0022] The beneficial effects of using this utility model are as follows:

[0023] The structural design of this utility model, which allows the left and right fixing blocks and the base plate to be separated, makes the disassembly of the module simple and quick.

[0024] The structural design of this utility model allows for clear observation of the curing state of the adhesive after application, ensuring that there is no risk of adhesive leakage when removing it.

[0025] With the structural design of this utility model, the overflowing glue will not be visible on the module, so there is no need to process the module. Attached Figure Description

[0033] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 2 , Figure 3 As shown, a PCB module potting fixture of this utility model includes a base plate 1, bolt holes 2 at the four corners of the base plate 1, locking bolts 3 are installed in the bolt holes 2, and a fixing structure 4 is installed on the base plate 1 through the bolt holes 2 and the locking bolts 3.

[0035] The fixing structure 4 includes a left fixing block 41 and a right fixing block 42. The left fixing block 41 and the right fixing block 42 are provided with through holes 43 that match the position and specifications of the locking bolt 3. Ear plates 44 are integrally connected to both sides of the left fixing block 41 and the right fixing block 42. Locking components 45 and disassembly components 46 are installed on the ear plates 44 on the same side of the left fixing block 41 and the right fixing block 42. PCB modules 5 are filled into the left fixing block 41 and the right fixing block 42.

[0036] In this implementation case, when using a PCB module potting fixture, the left fixing block 41 and the right fixing block 42 are first assembled. Then, the locking assembly 45 is used to lock the left fixing block 41 and the right fixing block 42 into a U-shape. Then, the left fixing block 41 and the right fixing block 42 are placed on the base plate 1 with the through hole 43 aligned with the bolt hole 2. The locking bolt 3 is inserted into the through hole 43 and into the bolt hole 2 to fix the left fixing block 41 and the right fixing block 42 on the base plate 1. This completes the forming of the fixture. The PCB module is placed between the left fixing block 41 and the right fixing block 42. Then, the glue is poured into the gap between the left fixing block 41, the right fixing block 42 and the PCB module. This method also allows the filling height of the glue to be observed, thereby determining the potting height.

[0037] After the adhesive has solidified, first remove the left fixing block 41 and the right fixing block 42 from the base plate 1, then completely remove the locking assembly 45 from the left fixing block 41 and the right fixing block 42, and then rotate the disassembly assembly 46 to separate the left fixing block 41 and the right fixing block 42 by pushing them open, thereby achieving the separation of the left fixing block 41 and the right fixing block 42 from the PCB module and achieving the purpose of demolding.

[0038] The preferred base plate 1 is provided with a sealing groove 6, in which a sealing ring 7 is placed. With this design, when the left fixing block 41 and the right fixing block 42 are installed on the base plate 1, the sealing position can be sealed by compressing the sealing ring 7. In fact, sealing measures can also be considered according to specific circumstances.

[0039] Preferably, the left fixing block 41 and the right fixing block 42 are provided with a protruding ridge 47 and a groove 48 opposite to each other, and the gap of the protruding ridge 47 matches the groove 48. This design serves to prevent mistakenly, position and enhance the sealing effect of the left fixing block 41 and the right fixing block 42. In fact, the splicing optimization structure between the left fixing block 41 and the right fixing block 42 can also be considered according to the specific situation.

[0040] The preferred locking assembly 45 includes a through hole 49 on the ear plate 44, in which a locking screw 410 is installed and a nut 411 is threadedly connected to the locking screw 410. With this design, the left and right fixing blocks can be fixedly connected by the locking screw and the nut. In fact, the structure of the locking assembly 45 can also be considered according to the specific situation.

[0041] The preferred disassembly assembly 46 includes a disassembly screw 412 threaded onto the ear plate 44 of the left fixing block 41. The end of the disassembly screw 412 contacts the ear plate 44 of the right fixing block 42. With this design, after the locking assembly is disassembled, turning the disassembly screw can push the left fixing block away from the right fixing block, thereby achieving the separation and disassembly of the two. In fact, the structure of the disassembly assembly 46 can also be considered according to the specific situation.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
