Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a PCB board cleaning and transfer device. Background Technology

[0002] PCB boards are carriers for electronic components, used for mechanical support and circuit connection. During the production process, impurities such as flux, dust, and oxides may remain on their surface. These impurities can affect circuit performance, leading to problems such as short circuits and poor contact. Cleaning PCB boards can remove these impurities, ensure stable circuit operation, and improve the reliability and lifespan of electronic products.

[0003] In existing PCB production processes, the cleaning process often relies on manual operation. Workers need to use hand tools to remove dust, solder slag, and residual flux from the surface of the PCB board one by one. This traditional cleaning method is not only inefficient, but manual operation is also prone to unstable cleaning quality due to factors such as fatigue, which in turn affects the subsequent assembly and use.

[0004] Therefore, this utility model proposes a PCB board cleaning and transfer device. Utility Model Content

[0005] The purpose of this invention is to provide a PCB board cleaning and transfer device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A PCB board cleaning and transfer device includes a cleaning frame. Four sets of extension plates are fixedly connected to the top of the cleaning frame. Two sets of rollers are movably sleeved on the opposite sides of the four sets of extension plates. A transmission belt is driven to the outer wall of the two sets of rollers. Several sets of clamping devices are fixedly connected to the outer wall of the transmission belt, one of which is movably sleeved with the cleaning frame.

[0008] Furthermore, the clamping device includes a connecting column, the connecting column having an internal telescopic groove, a connecting pull plate being movably sleeved inside the telescopic groove, a connecting pull rod being fixedly connected to the bottom end of the connecting pull plate, the outer wall of the connecting pull rod being slidably sleeved with the connecting column, one set of clamping blocks being fixedly connected to the bottom end of the connecting pull rod, the outer wall of the other set of clamping blocks being fixedly connected to the top end of the connecting column, and a spring being movably sleeved inside the connecting column, the top end of the spring being in contact with the connecting pull plate.

[0009] Furthermore, side baffles are fixedly connected to both sides of the outer wall of the clamping block. Two sets of circular holes are opened inside the side baffles. Limiting sleeve rods are slidably sleeved on the inner walls of the circular holes. Fixed clamping plates are fixedly connected to the inner walls of the limiting sleeve rods. One end of a second spring is fixedly connected to the outer wall of the fixed clamping plate. The other end of the second spring is fixedly connected to the inner wall of the side baffle.

[0010] Furthermore, one end of a hinged connecting block is fixedly connected to the top of one of the clamping blocks, and the other end of the hinged connecting block is fixedly connected to the transmission belt.

[0011] Furthermore, the cleaning frame is equipped with four sets of drive shafts arranged in a linear array, and each drive shaft has a cleaning brush fixedly connected to its outer wall.

[0012] Furthermore, one of the sets of cleaning brushes is provided on opposite sides of the two sets of cleaning brushes, and the connecting posts and cleaning brushes are arranged in an alternating array.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By fixing the PCB board inside the clamping device, the clamping device stably holds the PCB board, ensuring that it will not shift during the cleaning process. When the PCB board is inside the cleaning frame, the cleaning agent inside the cleaning frame fully soaks the stains attached to the surface of the PCB board, softening and loosening the stains. Subsequently, the cleaning brush cleans the surface of the PCB board, effectively removing residual stains and impurities. This automates the cleaning process, not only improving cleaning efficiency but also ensuring the stability of cleaning quality. This provides a good foundation for subsequent production processes and helps improve the efficiency of the entire production process and the reliability of the products.

[0015] 2. The front-end worker only needs to place the PCB board inside the clamping device. After cleaning, the clamping device automatically transfers the PCB board to the next process. The whole process does not require manual intervention, realizing efficient and stable automated cleaning and transmission, and providing strong support for subsequent production processes.

[0023] 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.

[0024] Please see Figures 1 to 5 As shown, the PCB board cleaning and transfer device provided by this utility model includes a cleaning frame 1. Four sets of extended upright plates 2 are fixedly connected to the top of the cleaning frame 1. Two sets of rollers 4 are movably sleeved on the opposite sides of the four sets of extended upright plates 2. A transmission belt 3 is drivenly connected to the outer wall of the two sets of rollers 4. Several sets of clamping devices are fixedly connected to the outer wall of the transmission belt 3, one of which is movably sleeved with the cleaning frame 1.

[0025] The clamping device includes a connecting column 8, which has a telescopic groove inside. A connecting pull plate 14 is movably sleeved inside the telescopic groove. A connecting pull rod 11 is fixedly connected to the bottom end of the connecting pull plate 14. The outer wall of the connecting pull rod 11 is slidably sleeved with the connecting column 8. One set of clamping blocks 10 is fixedly connected to the bottom end of the connecting pull rod 11. The outer wall of the other set of clamping blocks 10 is fixedly connected to the top end of the connecting column 8. A spring 12 is movably sleeved inside the connecting column 8. The top end of the spring 12 is in contact with the connecting pull plate 14.

[0026] Side baffles 9 are fixedly connected to both sides of the outer wall of the clamping block 10. Two sets of round holes are opened inside the side baffles 9. The inner wall of the round holes is slidably fitted with a limiting sleeve rod 15. The inner wall of the limiting sleeve rod 15 is fixedly connected with a fixing clamping plate 13. One end of a second spring 16 is fixedly connected to the outer wall of the fixing clamping plate 13. The other end of the second spring 16 is fixedly connected to the inner wall of the side baffle 9.

[0027] One end of a hinged connecting block 7 is fixedly connected to the top of one set of clamping blocks 10, and the other end of the hinged connecting block 7 is fixedly connected to the transmission belt 3.

[0028] The cleaning frame 1 has four sets of drive shafts 6 arranged in a linear array, and each drive shaft 6 has a cleaning brush 5 fixedly connected to its outer wall.

[0029] One of the two sets of cleaning brushes 5 is provided on opposite sides with a connecting column 8, and the connecting column 8 and the cleaning brushes 5 are arranged in an alternating array.

[0030] Working principle: Before cleaning, the worker first inserts the PCB board to be cleaned onto the opposite sides of the two sets of clamping blocks 10, with the other side fitting against the outer wall of the connecting column 8. When the length of the PCB board is longer than the length of the connecting column 8, the clamping block 10 at the bottom is pushed to move downwards. The downward-moving clamping block 10 simultaneously pulls the connecting rod 11 to slide inside the connecting column 8. At this time, under the influence of the elastic potential energy of the spring-12, the connecting pull plate 14 is pushed, which in turn pulls the spring-12 to maintain the extended distance, thereby causing the two sets of clamping blocks 10 to apply a clamping force to the PCB board, making P The CB board is clamped and fixed to the side of the connecting column 8. At the same time, two sets of side baffles 9 are fixedly connected to the upper and lower sides of the clamping block 10. The spring 16 fixed to the side of the side baffle 9 pushes the two sets of fixed clamping plates 13 to clamp and fix the PCB board fixed in the middle, further ensuring the stability of the PCB board during the cleaning process. A limiting sleeve 15 is set inside the spring 16. The outer wall of the limiting sleeve 15 is sleeved with the side baffle 9, so that the direction of the spring 16 remains stable during the extension and retraction movement, avoiding clamping deviation and other situations, further ensuring the stability of the PCB board during the cleaning process.

[0031] After the PCB board is clamped, the two sets of rollers 4 are driven by an external power source to rotate inside the extension plate 2, which in turn drives the transmission belt 3 to rotate. As the transmission belt 3 rotates, the clamping device, which was originally higher than the cleaning frame 1, rotates to the inside of the cleaning frame 1. The inside of the cleaning frame 1 is filled with a special cleaning solution for PCB boards, which soaks the surface of the PCB board to facilitate the removal of stains. At the same time, as the transmission belt 3 rotates, the connecting column 8 passes through the opposite sides of the two sets of cleaning brushes 5. At this time, the cleaning brushes 5 are driven by an external power source to rotate the transmission shaft 6, which further makes the cleaning brushes 5 rotate synchronously, so that the two sets of cleaning brushes 5 brush the PCB board surface that passes through the inside, thereby removing the stains attached to the PCB board surface.

[0032] After the PCB board is cleaned, the conveyor belt 3 continues to transport it to the other side. When the PCB board is higher than the cleaning frame 1, it can be removed, realizing an automated cleaning process. This not only improves cleaning efficiency but also reduces the tedious steps of manual operation and lowers the potential damage risk to the PCB board caused by manual handling and improper operation. At the same time, after cleaning, the PCB board is directly transported to the next process station, realizing the continuity of the production process and improving the overall production efficiency.

[0033] Finally, it should be noted that 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.
