Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, and specifically to a cleaning device for circuit board manufacturing. Background Technology
[0002] A circuit board, also known as a printed circuit board or PCB, is a carrier used to support and connect electronic components. It is typically made of non-conductive materials (such as glass fiber reinforced epoxy resin), with a surface covered by conductive copper foil, and circuit connections are formed through chemical etching or mechanical processing. Circuit boards provide the electrical connections for electronic components, significantly reducing wiring and assembly errors, improving automation levels and production efficiency. To ensure the quality of circuit board production, cleaning equipment is commonly used during the manufacturing process. Cleaning is a critical process step in circuit board manufacturing; its core function is to remove contaminants introduced during production, thereby ensuring the performance, reliability, and appearance quality of the circuit board.
[0003] However, most existing cleaning devices have fixed water outlets, resulting in a fixed water flow direction. This method is not effective and cannot thoroughly clean circuit boards, leaving cleaning dead spots, which reduces cleaning quality and further reduces work efficiency. Therefore, we provide a cleaning device for circuit board production. Utility Model Content
[0004] The purpose of this invention is to provide a cleaning device for circuit board production to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A cleaning device for circuit board production includes a water storage tank, a filter screen plate is movably inserted into the front side of the water storage tank, locking grooves are provided on both sides of the top of the water storage tank, and a support bracket is fixedly installed on the top of the water storage tank.
[0007] An angle rotation unit is provided at the rear end of the support bracket.
[0008] The angle rotation unit includes a limiting rod fixedly installed on the right side of the rear end of the support bracket. A brake tooth plate is slidably sleeved on the outer surface of the other end of the limiting rod. The length of the limiting rod is about half that of the brake tooth plate. It is inserted into the inside of the brake tooth plate. When the brake tooth plate reciprocates, it slides continuously on the outer surface of the limiting rod. The limiting rod limits the movement of the brake tooth plate and prevents it from deviating.
[0009] A further improvement of this utility model is that a hydraulic cylinder is fixedly installed on the left side of the rear end of the support bracket, a piston rod is provided at the extension end of the hydraulic cylinder, and the other end of the piston rod is fixedly installed on the left side of the brake tooth plate.
[0010] A further improvement of this utility model is that: fixed arc blocks are fixedly installed at both ends of the bottom of the support bracket, and a spray pipe is rotatably connected inside the fixed arc block, so that the fixed arc block can support and install the spray pipe.
[0011] A further improvement of the present invention is that: a nozzle is fixedly installed on the output end of the spray pipe, and multiple sets of nozzles are provided; a rotating gear is fixedly sleeved on the outer surface of the spray pipe, and the rotating gear meshes with a brake gear plate.
[0012] A further improvement of this utility model is that a circulation pump is fixedly installed on the rear side of the water storage tank, a liquid extraction pipe is fixedly installed on the input end of the circulation pump, and the other end of the liquid extraction pipe is fixedly installed inside the rear side of the water storage tank.
[0013] A further improvement of this utility model is that a drain pipe is fixedly installed on the output end of the circulating pump, and a water guide pipe is fixedly installed on the other end of the drain pipe.
[0014] A further improvement of this utility model is that a diversion pipe is fixedly installed on the output end of the water guide pipe, and the other end of the diversion pipe is movably sleeved on the outer surface of the input end of the spray pipe. The diversion pipe is rotatably connected to the input end of the spray pipe, so that the spray pipe will not affect the liquid entry when it rotates.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] 1. This utility model provides a cleaning device for circuit board production. By setting a hydraulic cylinder to push the piston rod, the brake tooth plate moves back and forth along its length. When the brake tooth plate moves back and forth, it intersects with the rotating gear to generate a driving force, which causes the rotating gear to drive each spray pipe to rotate around its own axis. This effectively expands the spray coverage area and makes the spray coverage more uniform, thereby improving the cleaning quality and further improving the cleaning efficiency.
[0017] 2. This utility model provides a cleaning device for circuit board production. By setting a filter screen, the liquid after spraying can be filtered and allowed to re-enter the water storage tank for reuse, thereby achieving the effect of resource conservation. Attached Figure Description

[0024] 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.
[0025] Example 1
[0026] like Figure 1-5As shown, this utility model provides a cleaning device for circuit board production, including a water tank 1. A filter screen 2 is movably inserted into the front side of the water tank 1. Engaging grooves 3 are provided on both sides of the top of the water tank 1. A support bracket 4 is fixedly installed on the top of the water tank 1. An angle rotation unit is provided at the rear end of the support bracket 4. The angle rotation unit includes a limiting rod 110 fixedly installed on the right side of the rear end of the support bracket 4. A brake tooth plate 19 is slidably sleeved on the outer surface of the other end of the limiting rod 110. The left side of the rear end of the support bracket 4... A hydraulic cylinder 42 is fixedly installed on the side. A piston rod 43 is provided at the extension end of the hydraulic cylinder 42. The other end of the piston rod 43 is fixedly installed on the left side of the brake tooth plate 19. Fixed arc blocks 41 are fixedly installed at both ends of the bottom of the support bracket 4. A spray pipe 16 is rotatably connected inside the fixed arc block 41. A nozzle 17 is fixedly installed on the output end of the spray pipe 16. Multiple sets of nozzles 17 are provided. A rotating gear 18 is fixedly sleeved on the outer surface of the spray pipe 16. The rotating gear 18 meshes with the brake tooth plate 19.
[0027] Furthermore, the hydraulic cylinder 42 pushes the piston rod 43 to cause the brake tooth plate 19 to move back and forth along its length. When the brake tooth plate 19 moves back and forth, it intersects with the rotating gear 18 to generate a driving force, which causes the rotating gear 18 to drive each spray pipe 16 to rotate around its own axis, thereby effectively expanding the spray coverage area and making the spray coverage surface more uniform.
[0028] Example 2
[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a circulation pump 11 is fixedly installed on the rear side of the water storage tank 1, a liquid extraction pipe 12 is fixedly installed on the input end of the circulation pump 11, the other end of the liquid extraction pipe 12 is fixedly installed inside the rear side of the water storage tank 1, a drain pipe 13 is fixedly installed on the output end of the circulation pump 11, a water guide pipe 14 is fixedly installed on the other end of the drain pipe 13, a diverter pipe 15 is fixedly installed on the output end of the water guide pipe 14, and the other end of the diverter pipe 15 is movably sleeved on the outer surface of the input end of the spray pipe 16.
[0030] Furthermore, the circuit board to be cleaned is inserted into the slot 3, and with the start of the circulation pump 11 and the liquid extraction pipe 12, the liquid inside the water tank 1 is drawn out. Then, with the help of the drain pipe 13, the water guide pipe 14, the diversion pipe 15 and the spray pipe 16, the liquid is transported to each nozzle 17, and the nozzle 17 sprays it evenly downwards to clean the circuit board.
[0031] The working principle of the cleaning device used in circuit board production will be explained in detail below.
[0032] like Figure 1-5As shown, during use, the circuit board to be cleaned is inserted into the locking groove 3. With the start of the circulation pump 11 and the liquid extraction pipe 12, the liquid inside the water storage tank 1 is drawn out. Then, with the help of the drain pipe 13, the guide pipe 14, the diversion pipe 15, and the spray pipe 16, the liquid is transported to each nozzle 17. The nozzles 17 spray the liquid evenly downwards to clean the circuit board. During the cleaning process, the hydraulic cylinder 42 pushes the piston rod 43 to cause the brake tooth plate 19 to move back and forth along its length. When the brake tooth plate 19 moves back and forth, it intersects with the rotating gear 18 to generate a driving force, causing the rotating gear 18 to drive each spray pipe 16 to rotate around its own axis, thereby effectively expanding the spray coverage area and making the spray coverage more uniform. The sprayed liquid flows downwards and is filtered by the filter screen 2 before flowing back into the water storage tank 1 for reuse.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
