Description

Technical Field

[0001] This utility model relates to the field of dispensing fixture technology, and in particular to a dispensing fixture for PCB boards. Background Technology

[0002] Dispensing is a process, also known as gluing, coating, potting, or dripping, in which electronic adhesives, oils, or other liquids are applied, potted, or dripped onto a product to achieve functions such as adhesion, encapsulation, insulation, fixation, and surface smoothing. To facilitate dispensing, fixtures are needed to fix and position the PCB board.

[0003] Existing PCB board dispensing fixtures require maintenance and replacement in actual use. Most of them are connected to the dispensing equipment with bolts, which is slow and does not improve the efficiency of dispensing and assembly.

[0004] A search of existing patents revealed a PCB board dispensing fixture (publication number: CN221537172U). This utility model utilizes a rectangular support frame, a drive mechanism, a tray, a bracket, and a clamping mechanism to assist in dispensing adhesive onto the PCB board. The tray can be cleaned after dispensing to prevent the adhesive from affecting subsequent dispensing. Furthermore, the fixture is easy to assemble and disassemble, improving maintenance efficiency and reducing the impact on dispensing operations.

[0005] While the aforementioned patent facilitates the assembly and disassembly of the fixture, due to the varying sizes of PCB boards, the dispensing fixture can only fix both sides, which does not improve the stability of the PCB board during the dispensing process. Utility Model Content

[0006] The purpose of this invention is to provide a dispensing fixture for PCB boards, which solves the problem mentioned in the background art of not being able to improve the stability of PCB boards during the dispensing process.

[0008] The clamping assembly includes plug-in blocks that are fixedly connected to the top surfaces of the adjusting block and the moving block, and clamping elements are plugged into the surface of the plug-in blocks;

[0009] The quick-release assembly includes an outer mounting post that is inserted into the mounting hole. A return spring is fixedly connected to the inner bottom wall of the outer mounting post. A limit post is fixedly connected to the top of the return spring. A thin post is fixedly connected to the top of the limit post. A quick-release post is fixedly connected to the top of the thin post. Three locking beads are provided inside the outer mounting post.

[0010] As a further embodiment of this utility model, the adjustment component includes a servo motor fixedly connected to the upper surface of one side of the fixture body. The output end of the servo motor is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a positive and negative threaded rod A, which facilitates the movement of the adjustment block.

[0011] As a further embodiment of this utility model, the positioning component includes a drive motor fixedly connected to the lower surface of the other side of the fixture body. The output end of the drive motor is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a positive and negative threaded rod B, which facilitates the movement of the moving block.

[0012] As a further embodiment of this utility model, the surface of the fixture body is provided with a cross-shaped groove, and the inner wall of the cross-shaped groove is provided with a sliding groove, which facilitates the sliding of the stabilizing block inside.

[0013] As a further embodiment of this utility model, stabilizing blocks are fixedly connected to both sides of the adjusting block and the moving block. The stabilizing blocks are adapted to the sliding groove, and the stabilizing blocks facilitate the improvement of the stability of the adjusting block and the moving block during movement.

[0014] As a further embodiment of this utility model, a fixing hole is provided on one side of both the clamping member and the plug-in block, and a fixing bolt is threaded inside the fixing hole. The fixing bolt facilitates the assembly and disassembly of the adjusting block, the moving block, and the clamping member.

[0015] As a further embodiment of this utility model, a slot is provided on the other side of the clamping member, and protective cotton is adhesively connected inside the slot, making it easy for the clamping member to clamp PCB boards of different sizes.

[0016] As a further embodiment of this utility model, three limiting holes are provided on the edge of the mounting outer column surface. The limiting holes are adapted to the retaining beads, and the retaining beads are easy to install with the dispensing equipment.

[0017] This utility model provides a dispensing fixture for PCB boards, which has the following advantages:

[0018] 1. This PCB board dispensing fixture, through the setting of adjustment components, positioning components, adjustment blocks, moving blocks, and clamping components, activates servo motors and drive motors according to the size of the PCB board during use. The positive and negative threaded rod A moves two adjustment blocks, and the positive and negative threaded rod B moves two moving blocks, allowing the clamping components to clamp the PCB board around its perimeter. This achieves the function of fixing and positioning PCB boards of different sizes, preventing the PCB board from moving during the use of the dispensing fixture and improving the stability of the PCB board during the dispensing process.

[0019] 2. This PCB board uses a dispensing fixture with a quick-release assembly. When maintenance or replacement of the dispensing fixture is required, press the quick-release post, the return spring depresses, and the retaining ball retracts into the thin post. Remove the outer post for maintenance or replacement. Repeat the same process: place the dispensing fixture onto the dispensing equipment, insert the outer post into the limiting hole and the external connection hole on the dispensing equipment, release the quick-release post, the return spring rises, and the limiting post pushes the retaining ball out of the limiting hole, thus fixing it in place. This achieves quick disassembly and installation of the dispensing fixture, avoiding the need for bolts to connect to the dispensing equipment, which is slower and improves efficiency.
