Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing support fixtures, specifically a printed circuit board processing support fixture. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), printing and bonding are performed sequentially. Currently, printing and bonding typically use two separate fixtures, increasing production costs. Furthermore, transferring the PCB to the bonding fixture after printing usually requires additional robotic arms or manual labor, further increasing costs; and there is a risk of damage to the PCB during the transfer process.

[0003] A search revealed existing technology (application number: CN202311189892.X) for a printed circuit board (PCB) support fixture, which describes "a PCB support fixture. The PCB support fixture includes a main support component, an auxiliary support component, and a drive component. The main support component supports the PCB and has a first positioning through-hole. The auxiliary support component is located below the main support component and has a positioning post and a first magnetic component. The positioning post can be placed in the first positioning through-hole and extends beyond the upper surface of the first positioning through-hole." This utility model has a simple structure and provides more precise and reliable support.

[0004] However, while existing technologies are simpler in structure and more precise and reliable in load bearing, they still have some shortcomings: they cannot securely clamp the circuit board. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a printed circuit board processing support fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a printed circuit board processing support fixture, a support box including a circuit board tray fixedly arranged inside the support box, and a circuit board arranged on the circuit board tray, and an ultraviolet lamp tube inside the support box for processing the circuit board; a clamping mechanism including a motor fixedly arranged above the support box, and a gear fixedly arranged at the output end of the motor for driving the clamping assembly for clamping the circuit board.

[0007] As a further description of the above technical solution:

[0008] The clamping assembly includes: a sliding groove arranged on a circuit board tray; a clamping plate that slides on the sliding groove via sliding blocks fixed on both sides; and a driving assembly arranged on one side of the clamping plate.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a rack arranged on one side of the clamping plate.

[0011] As a further description of the above technical solution:

[0012] A clamping block is fixedly arranged below the clamping plate; a rubber clamping strip is fixedly arranged on one side of the clamping block.

[0013] As a further description of the above technical solution:

[0014] The rack meshes with the gear, and the two sets of racks move in opposite directions.

[0015] As a further description of the above technical solution:

[0016] The rubber clamping strip is made of soft rubber and is used to clamp the circuit board.

[0017] As a further description of the above technical solution:

[0018] The clamping assembly is provided in two sets and is symmetrically arranged on both sides of the gear for synchronously clamping the circuit board.

[0019] This utility model has the following beneficial effects:

[0020] 1. By symmetrically arranging two sets of clamping components on both sides of the gear, and with the rack moving in opposite directions, the circuit board can be clamped simultaneously from both sides, ensuring uniform distribution of clamping force and effectively preventing displacement of the circuit board during processing.

[0021] 2.

[0027] 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.

[0028] Example 1:

[0029] like Figures 1 to 4 As shown, this embodiment provides a printed circuit board processing support fixture, including: a support box 1, including a circuit board tray 11 fixedly arranged inside the support box 1, and a circuit board 3 to be processed is arranged on the circuit board tray 11, and an ultraviolet lamp tube 12 is provided inside the support box 1 for processing the circuit board 3; a clamping mechanism 2, including a motor 201 fixedly arranged above the support box 1, and a gear 202 fixedly provided at the output end of the motor 201 for driving the clamping assembly for clamping the circuit board 3 to be processed.

[0030] In this embodiment, the support box 1 and the clamping mechanism 2 constitute the printed circuit board processing support fixture device involved in this application, realizing a printed circuit board processing support fixture.

[0031] In this embodiment, the circuit board 3 to be processed is placed on the circuit board tray 11, and the ultraviolet lamp 12 emits ultraviolet light to process the circuit board 3.

[0032] In this embodiment, the clamping assembly avoids damage to the circuit board during the clamping process. The clamping force of the clamping assembly can be adjusted according to the thickness of the circuit board and the processing requirements to ensure that the circuit board remains stable during the processing.

[0033] It should be noted that the material of the supporting box 1 can be metal, providing an enclosed space for circuit board processing.

[0034] Specifically, the clamping assembly includes: a sliding groove 206 arranged on the circuit board support plate 11; a clamping plate 203 that slides on the sliding groove 206 via sliding blocks 205 fixed on both sides; and a driving assembly arranged on one side of the clamping plate 203.

[0035] In this embodiment, the motor 201 drives the gear 202 to rotate. The gear 202 cooperates with the drive component to make the clamping plate 203 slide on the sliding groove 206, thereby clamping the circuit board 3 to be processed.

[0036] Specifically, the drive assembly includes a rack 204, which is arranged on one side of the clamping plate 203.

[0037] In a preferred embodiment, the motor 201 drives the gear 202 to rotate, and the gear 202 meshes with the rack 204, converting the rotation of the gear 202 into the linear motion of the rack 204, thereby driving the clamping plate 203 to move.

[0038] Specifically, the clamping block 207 is fixedly arranged below the clamping plate 203; the rubber clamping strip 208 is fixedly arranged on one side of the clamping block 207.

[0039] It should be noted that when the clamping plate 203 moves, it drives the clamping block 207 and the rubber clamping strip 208 to move, and the rubber clamping strip 208 contacts and clamps the circuit board 3 to be processed.

[0040] Example 2:

[0041] Based on Example 1, in order to further improve the clamping protection of the circuit board 3 to be processed, a rubber clamping strip 208 is arranged on the clamping block 207 to clamp and protect the circuit board 3.

[0042] Specifically, the rack 204 meshes with the gear 202, and the two sets of racks 204 move in opposite directions.

[0043] In a preferred embodiment, the motor 201 drives the gear 202 to rotate clockwise or counterclockwise. Since the two sets of racks 204 mesh with different parts of the gear 202, the two sets of racks 204 move in opposite directions, thereby driving the clamping plates 203 on both sides to move towards or away from each other.

[0044] Specifically, the rubber clamping strip 208 is made of soft rubber and is used to clamp the circuit board 3 to be processed.

[0045] It should be noted that when clamping the circuit board 3 to be processed, the soft rubber material can undergo a certain deformation, better conforming to the surface of the circuit board 3 to be processed, increasing the contact area and friction, while avoiding scratches or damage to the circuit board 3 caused by excessively hard materials.

[0046] Specifically, the clamping assembly is provided in two sets and is symmetrically arranged on both sides of the gear 202 for synchronously clamping the circuit board 3 to be processed.

[0047] In this embodiment, the motor 201 drives the gear 202 to rotate, and through meshing with the racks 204 on both sides, the clamping components on both sides move synchronously, and clamp the circuit board 3 to be processed.

[0048] In use, after the photomask is applied to the circuit board 3 to be processed, the user places the circuit board 3 on the circuit board tray 11 inside the carrier box 1. At this time, the motor 201 is started, and the output gear 202 of the motor 201 rotates. The gear 202 meshes with two racks 204 and moves towards the middle in opposite directions. The clamping blocks 207 under the corresponding two sliding blocks 205 also move towards the middle. The rubber clamping strip 208 clamps the circuit board 3 and fixes it in place. The rubber material of the rubber clamping strip 208 is rubber to prevent damage to the circuit board 3 to be processed. The ultraviolet lamp 12 is turned on to irradiate the circuit board 3 covered with the photomask. (The part of the photomask with circuit is transparent, and the non-circuit part is black.) Under the transparent part of the photomask, the circuit board 3 to be processed will undergo a polymerization reaction and solidify.

[0049] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
