Description

Technical Field

[0001] The invention relates to the technical field of circuit board film stripping, in particular to a circuit board film stripping device which is convenient for scraping and collecting waste liquid. Background Art

[0002] With the rapid development of the electronics industry, flexible circuit boards have been widely used in various electronic devices due to their excellent bending performance and light weight. In the manufacturing process of flexible circuit boards, film stripping is a crucial process, which involves removing excess film layers on the circuit board to prepare for subsequent circuit wiring or other process steps.

[0003] The existing patent announcement number CN222053480U is a film stripping device that is convenient for scraping and collecting waste liquid. When stripping the film on the circuit board, the circuit board enters the equipment horizontally during the process of spraying the liquid medicine. In this way, the waste on the circuit board is not easy to be scraped clean after spraying the liquid medicine, which will cause debris to remain on the circuit board, resulting in poor cleaning effect. In addition, when loading the circuit board, the clamp needs to be opened first, and then the two ends of the circuit board need to be clamped. This back and forth operation is time-consuming and labor-intensive, very inconvenient, and only one circuit board can be stripped at a time, which reduces the overall efficiency. At the same time, when filtering the liquid medicine after spraying, there is a lack of safety protection measures, and the liquid medicine is easy to splash everywhere when it falls, causing pollution or harm to the staff.

When the rotating disk 807 is controlled by the connecting shaft 804 to lock the collecting box 701, the connecting shaft 804 synchronously controls the driving disk 901 to rotate, and the groove 903 on the side wall of the driving disk 901 interferes with the top rod. Since one end of the top plate 904 is an arc-shaped structure, the top plate 904 is interfered and slid by the groove 903, so that the top plate 904 squeezes the air storage bag 902, so that the gas inside the air storage bag 902 enters the inside of the sealing ring 704, and the sealing ring 704 expands and fits tightly with the inner side of the water storage tank 1 to make the sealing better.

[0051] When the present invention is in use, firstly, the installation of multiple support frames 201 facilitates the support and placement of the water tank 1 to be stable, and the installation of multiple rollers 206 facilitates the connection of the conveyor belt 203, and the installation of multiple pressure wheels 207 facilitates the squeezing of the edge of the conveyor belt 203, so that the conveyor belt 203 can be discharged in the water tank 1 in an inverted "convex" shape, and the operation of multiple first motors 202 facilitates the drive control of the conveyor belt 203, so that the circuit board can be well transported to the medicine liquid at the bottom of the water tank 1 for immersion and defilming, and the installation of the protective cover 204 facilitates the shielding and protection of the two ends of the top of the water tank 1, and the connection between the control valve 205 and the external pipeline facilitates the transportation of medicine liquid to the water tank 1, which is convenient for filling or exporting the medicine liquid, and multiple The symmetrical installation of the fixing seat 302 is conducive to the installation of multiple symmetrical clamping plates 301. Under the resistance of the compression spring 304, the two sliders 303 will drive the two clamping plates 301 to approach each other, so as to achieve stable clamping of the circuit board. The opening of the guide groove 305 is conducive to the insertion of the circuit board between the two clamping plates 301. The circuit board and the two clamping plates 301 are vertically clamped to realize the conveyor belt 203 to convey the circuit board to the inside of the water storage tank 1 for film removal. The vertical placement of the circuit board is conducive to the good drainage of waste liquid and is not easy to remain. The installation of the driving rod 403 is conducive to the driving control of one of the clamping plates 301. When the conveyor belt 203 moves to a certain position, the driving rod 403 on the outside of the clamping plate 301 conflicts with the clamping plate 402. The driving rod 403 is pressed against the clamping plate 301 by the resistance, so that the clamping plate 301 drives the slider 303 to get rid of the elastic force of the compression spring 304 and slide, so that the two clamping plates 301 are separated, which is convenient for loading or removing the circuit board. After the conveyor belt 203 moves to a certain position again, the driving rod 403 is separated from the clamping plate 402, and the clamping plate 301 is reset. The two clamping plates 301 are close to each other to stabilize the circuit board, which is convenient for subsequent film removal. The installation of the guide wheel 404 is conducive to the guiding effect when the driving rod 403 conflicts with the clamping plate 402, and the driving rod 403 will not be worn. At the same time, the installation of the mounting block 401 is conducive to the detachable connection between the clamping plate 402 and the mounting block 401 through the clamping slot 405, which is convenient for subsequent maintenance. It is beneficial to extract the filtered liquid medicine on the inner side of the bottom of the water storage tank 1, and transport it to the inside of multiple delivery pipes 502 through the connecting pipe 505, and the multiple delivery pipes 502 allow the liquid medicine to be sprayed out through the spray hole 504 on one side of the vertical plate 503, which is beneficial to spray both sides of the circuit board transported on the conveyor belt 203, so that the circuit board can be better stripped. Through the installation of multiple sets of symmetrical second motors 601, it is beneficial to connect the rotating shaft 604, and then realize the installation of multiple sets of symmetrical scrapers 602. Through the rotation of multiple sets of second motors 601, the rotation control of multiple sets of symmetrical scrapers 602 is realized. The scraper 602 is located at the bottom of the conveyor belt 203, which is beneficial to scrape the residual film on both sides of the circuit board after spraying, so that the film stripping effect is better. Through the installation of the control board 605,It is convenient to control the rotating shaft 604. Through the sliding connection between the output shaft of the second motor 601 and the inside of the rotating shaft 604, under the control of the two electric push rods 606, the position of the control board 605 is controlled, so that the control board 605 drives the rotating shaft 604 to slide on the motor output shaft, thereby adjusting the position of the scraper 602 and the circuit board, which is convenient for scraping circuit boards of different thicknesses and preventing damage to the circuit board. The installation of the collection box 701 is convenient for the installation of the filter cotton 703. The collection box 701 is inserted into the inner side of the bottom of the water storage tank 1, which is convenient for collecting the liquid spraying the circuit board, and the liquid is filtered and defilmed through the filter cotton 703. The filtered liquid medicine flows into the bottom of the water storage tank 1 and is pumped out by the water pump 501 for spraying again. The installation of the handle 702 facilitates the holding and disassembly of the collection box 701. The installation of the sealing ring 704 facilitates the collection box 701 to be inserted into the water storage tank 1 to play a sealing role to prevent the liquid medicine from overflowing. After the collection box 701 is inserted into the water storage tank 1, the connection block 802 is rotated, and the connection block 802 drives the turntable 807 to rotate through the connecting shaft 804, so that the driving groove 808 at the edge of the turntable 807 is in conflict with the limit rod 810. Since one end of the limit rod 810 is a hemispherical structure, the limit rod 810 is resisted. The contact slides out under the elastic force of the extrusion spring 806, so that the two limit rods 810 slide out and insert into the limit groove 805, thereby limiting the position between the collection box 701 and the water storage tank 1. By rotating the connecting block 802 in the opposite direction, the driving groove 808 on the turntable 807 is aligned with the limit rod 810, which is convenient for the limit rod 810 to reset and shrink, and then the collection box 701 is drawn out. The opening of the positioning groove 809 is conducive to the turntable 807 rotating a certain angle to contact the limit rod 810, and the limit rod 810 can be engaged with the inside of the positioning groove 809, thereby playing a positioning role, so that the turntable 807 will not rotate at will. The design of the arc structure facilitates the smooth driving control of the limit rod 810. The installation of two air storage bags 902 facilitates the storage of gas. When the rotating disk 807 is locked to the collection box 701 by the connecting shaft 804, the connecting shaft 804 synchronously controls the driving disk 901 to rotate, and the groove 903 on the side wall of the driving disk 901 resists the top rod. Since one end of the top plate 904 is an arc structure, the top plate 904 is resisted and slid by the groove 903, so that the top plate 904 squeezes the air storage bag 902, so that the gas inside the air storage bag 902 enters the inside of the sealing ring 704, and the sealing ring 704 expands and fits tightly with the inner side of the water storage tank 1, so that the sealing performance is better.
