Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, specifically to a flexible circuit board surface treatment device. Background Technology

[0002] Flexible circuit boards (PCBs) are printed circuit boards made of flexible insulating substrates such as polyimide or polyester film. They can be freely bent, rolled, and folded, greatly reducing the size of electronic products. They are suitable for the needs of electronic products developing towards high density, miniaturization, and high reliability, and are widely used in many electronic devices such as mobile phones, tablets, digital cameras, and wearable devices. During the production process of flexible circuit boards, dust and impurities are easily attached to their surface. If these contaminants are not removed in time, they will affect the performance and reliability of the circuit board, such as causing short circuits and poor contact. They will also have an adverse effect on subsequent processes such as soldering, coating, and assembly, reducing product quality and yield.

[0003] Flexible circuit board surface treatment devices clean impurities and dust from the surface, improving the cleanliness of the circuit board surface and ensuring the quality of subsequent processing. However, if the dust raised during the cleaning process is not effectively collected, it may re-adhere to the circuit board surface or spread into the working environment, causing the cleaning to fail. Utility Model Content

[0004] The purpose of this invention is to provide a flexible circuit board surface treatment device to solve the problem of cleaning failure caused by dust re-adhesion mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible circuit board surface treatment device, comprising a base and side plates, a sliding rod is horizontally installed between the side plates, and a cleaning plate is slidably installed on the outer wall of the sliding rod, a servo motor is installed on one side of the side plate, and a one-way threaded rod is installed at the output end of the servo motor, and a collection structure for absorbing dust is also included.

[0006] The collection structure includes an absorption port, which is installed on both sides of the top of the base. An absorption pipe is installed on the side of the absorption port that is far apart from each other. A collection box is installed at the middle of the bottom of the base. Filter drawers are slidably installed on both sides inside the collection box. A fan is installed at the bottom of the collection box.

[0007] Preferably, a carrying plate is installed at the middle position of the top of the base, and a groove is opened inside the top of the carrying plate. A bidirectional threaded rod is rotatably installed at the rear end of the groove. A knob is installed at the front end of the bidirectional threaded rod. Two threaded blocks are connected to the outer wall of the bidirectional threaded rod by threads, and a fixing plate is installed at the top of the threaded blocks.

[0008] Preferably, the threaded blocks are located at two parts of the outer wall of the bidirectional threaded rod in opposite directions, and the two threaded blocks move in opposite directions.

[0009] Preferably, one end of the one-way threaded rod passes through the cleaning plate, and the cleaning plate and the one-way threaded rod are connected by threads.

[0010] Preferably, the bottom end of the absorption tube passes through the base and the collection box in sequence, and the bottom end of the absorption tube extends to one side inside the collection box.

[0011] Preferably, the absorption port and the absorption pipe are interconnected, and the fan and the collection box are interconnected.

[0012] Preferably, the front end of the bidirectional threaded rod passes through the carrying plate, and the front end of the bidirectional threaded rod extends to the front end of the carrying plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: when the fan is started, the suction force generated by the fan causes the suction port to be generated, and the swept dust can enter the interior of the suction pipe through the suction port, and then enter the interior of the collection box through the suction pipe. Subsequently, it is filtered through the filter drawer, and the dust enters the interior of the filter drawer. Excess air is discharged through the fan. This structure absorbs the swept dust through the action of the fan, the suction pipe and the suction port, preventing the dust from re-adhering to the surface of the flexible circuit board.

A slide bar 4 is horizontally installed between the side plates 2, and a cleaning plate 3 is slidably installed on the outer wall of the slide bar 4. A servo motor 6 is installed on one side of the side plate 2, and a one-way threaded rod 5 is installed at the output end of the servo motor 6. The device also includes a collection structure for absorbing dust.

[0021] The collection structure includes an absorption port 7, which is installed on both sides of the top of the base 1. An absorption pipe 12 is installed on the side of the absorption port 7 that is far apart from each other. A collection box 11 is installed at the middle of the bottom of the base 1. Filter drawers 9 are slidably installed on both sides inside the collection box 11. A fan 10 is installed at the bottom of the collection box 11.

[0022] A carrying plate 8 is installed at the top center of the base 1, and a groove 16 is opened inside the top of the carrying plate 8. A two-way threaded rod 15 is rotatably installed at the rear end inside the groove 16. A knob 13 is installed at the front end of the two-way threaded rod 15. Two threaded blocks 17 are connected to the outer wall of the two-way threaded rod 15 by threads, and a fixing plate 14 is installed at the top of the threaded blocks 17.

[0023] Specifically, such as Figure 1 and Figure 4 As shown, the threaded blocks 17 are located at two parts of the outer wall of the bidirectional threaded rod 15 in opposite directions, and the two threaded blocks 17 move in opposite directions. In use, the bidirectional threaded rod 15 is rotated by the knob 13, so that the threaded blocks 17 move towards each other on the outer wall of the bidirectional threaded rod 15.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, one end of the one-way threaded rod 5 passes through the cleaning plate 3, and the cleaning plate 3 and the one-way threaded rod 5 are connected by threads. The front end of the two-way threaded rod 15 passes through the carrying plate 8, and the front end of the two-way threaded rod 15 extends to the front end of the carrying plate 8. When in use, the servo motor 6 is started to drive the one-way threaded rod 5 to rotate, so that the cleaning plate 3 moves left and right on the outer wall of the one-way threaded rod 5, and the flexible circuit board is cleaned by the cleaning plate 3.

[0025] Specifically, such as Figure 1 and Figure 2As shown, the bottom end of the absorption tube 12 passes through the base 1 and the collection box 11 in sequence, and the bottom end of the absorption tube 12 extends to one side inside the collection box 11. The absorption port 7 is connected to the absorption tube 12, and the fan 10 is connected to the collection box 11.

[0026] Working principle: The operator places the flexible circuit board to be cleaned between the fixed plates 14 at the top of the carrier plate 8, and then rotates the knob 13. The knob 13 drives the bidirectional threaded rod 15 to rotate, causing the threaded blocks 17 to move closer to each other on the outer wall of the bidirectional threaded rod 15. The threaded blocks 17 drive the fixed plates 14 to move closer to each other, thus fixing the flexible circuit board. Then, the servo motor 6 is started, driving the unidirectional threaded rod 5 to rotate, causing the cleaning plate 3 to move left and right on the outer wall of the unidirectional threaded rod 5. The cleaning plate 3 cleans the flexible circuit board. Then, the fan 10 is started. The fan 10 generates suction at the suction port 7, and the cleaned dust enters the suction tube 12 through the suction port 7 and then enters the collection box 11 through the suction tube 12. The dust is then filtered through the filter drawer 9, and the excess air is discharged through the fan 10.
