Description

Technical Field

[0001] This utility model relates to the field of circuit board dispensing technology, specifically to a circuit board mounting dispensing device. Background Technology

[0002] In the assembly of electronic devices, the dispensing of adhesive onto circuit boards is a crucial step. Adhesive dispensing is typically used to secure components, encapsulate contacts, provide insulation, or prevent the intrusion of moisture and contaminants. Precise control of the amount and placement of adhesive ensures that components adhere firmly to the circuit board, effectively improving the circuit's shock resistance and durability. Furthermore, dispensing helps reduce short circuits or failures caused by poor component contact, ensuring the stability and reliability of the circuit board. With technological advancements, the precision and efficiency of dispensing technology continue to improve, making it an indispensable process in modern electronic device manufacturing.

[0003] According to Chinese Patent No. CN221208783U, a circuit board dispensing device includes a worktable; a dispensing assembly is provided on the worktable, and the dispensing assembly includes a sliding block for dispensing adhesive onto the circuit board; a telescopic rod is fixedly connected to the bottom of the sliding block; a work box is fixedly connected to the output end of the telescopic rod; a dispensing tube is fixedly connected to the end of the work box that is not connected to the telescopic rod. By placing the circuit board on the worktable, fixing the circuit board with a clamp, and then moving the telescopic rod at the bottom of the sliding block up and down to bring the work box and the dispensing tube at the bottom of the work box closer to the circuit board, the dispensing tube dispenses adhesive onto the circuit board.

[0004] In the above solution, rotating the handle moves the lead screw, which in turn moves the fixing clamp to fix the circuit board. However, this method still has the following drawbacks: it relies on manual operation, which not only increases the complexity of the operation but may also lead to low efficiency. Furthermore, it may not be accurate enough when fixing manually, affecting the stability and reliability of the entire fixing process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circuit board mounting and dispensing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A circuit board mounting and dispensing device includes a base, a mounting box connected to the top surface of the base, two first racks and two second racks slidably disposed inside the mounting box, one end of each of the two first racks being connected to a first clamping plate, and one end of each of the two second racks being connected to a second clamping plate, a first motor disposed inside the mounting box, the output end of the first motor being connected to a first gear, and both of the first racks meshing with the first gear, and a second motor disposed inside the mounting box, the output end of the second motor being connected to a second gear, and both of the second racks meshing with the second gear.

[0008] Preferably, a third motor is connected to one side of the base, and a first lead screw is connected to the output end of the third motor. A mounting bracket is threaded onto the outer wall of the first lead screw.

[0009] Preferably, a fourth motor is connected to one side of the mounting bracket, a second lead screw is connected to the output end of the fourth motor, a moving block is threaded onto the outer wall of the second lead screw, and a dotted tube is connected to the bottom surface of the moving block.

[0010] Preferably, a first guide rod is connected to one inner wall of the base, and the outer wall of the first guide rod is slidably connected to the mounting bracket.

[0011] Preferably, a second guide rod is connected to one inner wall of the mounting bracket, and the outer wall of the second guide rod is slidably connected to the moving block.

[0012] Preferably, the top surface of the mounting box is connected to a workbench, and both the first clamping plate and the second clamping plate are disposed on the top surface of the workbench.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the circuit board to be glued on the workbench, starts the first motor, and the output end of the first motor drives the gear to rotate. Since both first racks mesh with the first gear, they move. The movement of the first racks causes the two first clamping plates to move towards the center position, thus firmly clamping the circuit board in the center of the workbench, ensuring its fixed and accurate position. The second motor is then started, and the output end of the second motor drives the second gear to rotate. Since the two second racks mesh with the second gear, they move. The movement of the second racks causes the two second clamping plates to move, further clamping and fixing the circuit board. This design structure does not rely on manual intervention, but automatically clamps the circuit board through mechanization, avoiding errors in human operation, thus greatly improving the accuracy and efficiency of the clamping process.

[0021] More specifically, during use, the operator places the circuit board to be glued on the workbench 20, starts the first motor 7, and the output of the first motor 7 drives the gear to rotate. Since both first racks 3 are meshed with the first gear 8, the first racks 3 are moved. The movement of the first racks 3 causes the two first clamping plates 5 to move towards the center position, thereby firmly clamping the circuit board in the center of the workbench 20, ensuring its fixed and accurate position. The second motor 9 is started, and the output of the second motor 9 drives the second gear 10 to rotate. Since the two second racks 4 are meshed with the second gear 10, the second racks 4 are moved. The movement of the second racks 4 causes the two second clamping plates 6 to move, further clamping and fixing the circuit board.

[0022] In this utility model, a third motor 11 is connected to one side of the base 1, and a first lead screw 12 is connected to the output end of the third motor 11. A mounting bracket 13 is threadedly connected to the outer wall of the first lead screw 12.

[0025] More specifically, the fourth motor 14 is started, and its output end drives the second lead screw 15 to rotate. The rotation of the second lead screw 15 drives the moving block 16 to move, and the movement of the moving block 16 drives the dispensing tube 17 to move.

[0026] In this utility model, a first guide rod 18 is connected to the inner wall of one side of the base 1, and the outer wall of the first guide rod 18 is slidably connected to the mounting bracket 13.

[0027] More specifically, the first guide rod 18 provides a stable guide path to ensure that the mounting bracket 13 remains on a predetermined track or in a predetermined direction during sliding, avoiding deviation or instability.
