[0002] Patent number CN116614947B discloses a PCB circuit board exposure device. When the device uses a pressure roller to scrape the photosensitive film flat, it will not cause wrinkles on the edge during the process of expelling bubbles between the copper clad board and the photosensitive film.

[0003] However, the above-mentioned existing PCB circuit board exposure equipment places the photosensitive film directly on the copper-clad board. Due to the intervention of air, bubbles are easily formed in the middle. Even if the surface is scraped flat with a laminating tool, it is difficult to expel the bubbles in the middle, which is likely to cause damage to the photosensitive film and affect the quality. Utility Model Content

[0004] The purpose of the present utility model is to provide an exposure processing device based on PCB circuit board processing, so as to solve the problem raised in the above background technology that when the photosensitive film is directly placed on the copper-clad board, bubbles are likely to appear in the middle due to the intervention of air. Even if the surface is scraped flat with a fitting tool, it is difficult to discharge the bubbles in the middle, which is likely to cause damage to the photosensitive film and affect the quality.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] Furthermore, the controller is electrically connected to the telescopic cylinder, the controller is electrically connected to the suction pump, and the controller is electrically connected to the electric slide rail.

[0011] Furthermore, the output end of the suction pump is communicated with the suction cup, the upper end surface of the workbench is provided with a groove, and the surface of the copper-clad plate is sleeved in the groove.

[0012] Furthermore, the processing component further includes a protective pad, a fixing plate, a threaded rod, a knob, a cutting groove and a cutting knife;

[0013] A protective pad is overlapped on the left side of the copper clad plate, and a fixed plate is overlapped on the left side of the protective pad. A threaded rod is rotatably connected to the inner wall of the fixed plate, and a knob is fixedly connected to the left end of the threaded rod.

[0017] 1. The utility model is equipped with a suction cup, an air suction pump, a telescopic cylinder, a controller and a rubber scraper. When one side of the coating film is attached to the copper clad laminate, the controller drives the electric slide rail, the telescopic cylinder and the air suction pump to work. When the electric slide rail is working, it drives the electric slider to control the electric slider to slide in the electric slide groove, so that the rubber scraper moves to the left along the upper side of the coating film. At the same time, the telescopic cylinder will cooperate with the movement of the rubber scraper to slowly control the suction cup to drive one side of the coating film to move downward.

When the threaded rod rotates clockwise, the fixing plate and the protective pad can be controlled to move toward the copper clad laminate until they hit the surface, thereby ensuring the stability of the copper clad laminate on the workbench and making the laminating film more stable during lamination. When the cutting knife slides in the cutting groove, the excess laminating film on both sides can be cut. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-4 As shown, this embodiment is an exposure processing device based on PCB circuit board processing, including:

[0030] Processing components, the processing components include a workbench 1;

[0031] The workbench 1 serves as the main body and is in contact with the ground, which can ensure the stability of the device during operation.

[0032] Add components, including a fixed frame 7, a controller 8, a telescopic cylinder 6, an air suction pump 5, a suction cup 4, a photosensitive film 3, a rubber scraper 14, a copper clad plate 2, an electric slide rail 9, an electric slider 10, a fixed block 11 and a connecting rod 12.

[0033] The left side of the processing component is fixedly connected to a fixed frame 7, the upper end surface of the fixed frame 7 is installed with a controller 8, the lower end surface of the fixed frame 7 is rotatably installed with a telescopic cylinder 6, the telescopic end of the telescopic cylinder 6 is installed with an air suction pump 5, the output end of the air suction pump 5 is installed with a suction cup 4, the lower end surface of the suction cup 4 adsorbs a photosensitive film 3, the upper end surface of the photosensitive film 3 is overlapped with a rubber scraper 14, the lower end surface of the photosensitive film 3 is attached to the copper clad plate 2, the upper end surface of the workbench 1 is provided with an electric slide rail 9, an electric slider 10 is transmitted in the electric slide rail 9, the upper end surface of the electric slider 10 is fixedly connected to a fixed block 11, two fixed blocks 11 are provided, and the opposite sides of the two fixed blocks 11 are fixedly connected to a connecting rod 12;

[0034] The fixed frame 7 provides support for the controller 8, telescopic cylinder 6, suction pump 5 and suction cup 4 to ensure the stable and normal operation of the structure. The suction cup 4 can lift one side of the coating film and move it downward according to the degree of adhesion. When the rubber scraper 14 moves on the surface of the coating film, it can tightly adhere the coating film to the copper clad plate 2. The electric slide rail 9 controls the movement of the electric slider 10.

[0035] The controller 8 is electrically connected to the telescopic cylinder 6, the controller 8 is electrically connected to the suction pump 5, and the controller 8 is electrically connected to the electric slide rail 9;

[0036] The suction pump 5 can control the suction cup 4 to move one side of the coating film downward through suction;

[0037] The controller 8 is electrically connected to the telescopic cylinder 6, the controller 8 is electrically connected to the suction pump 5, and the controller 8 is electrically connected to the electric slide rail 9;

[0038] Working principle: When the staff puts one side of the coating film on the copper clad laminate 2, the controller 8 starts the suction pump 5 to use the suction cup 4 to suck the other side of the coating film to prevent the coating film from being completely attached to the copper clad laminate 2 and causing bubbles in the middle. At this time, the electric slide 9 starts to control the electric slider 10 to drive the rubber scraper 14 to move to the left along the upper side of the coating film, so that the lower side of the coating film is tightly attached to the upper side of the copper clad laminate 2. At this time, the telescopic cylinder 6 cooperates with the movement of the rubber scraper 14 to control the suction pump 5 to move downward, so that the rubber scraper 14 gradually scrapes the coating film flat. During this process, the cutting knife 13 slides synchronously in the cutting groove 15 to cut the excess coating film on both sides.

[0039] See also Figure 1-4 As shown, this embodiment is based on the above embodiment 1;

[0040] The processing components also include a protective pad 18, a fixing plate 17, a threaded rod 16, a knob, a cutting groove 15 and a cutting knife 13;

A threaded rod 16 is rotatably connected to the inner wall of the fixed plate 17, and a knob is fixedly connected to the left end of the threaded rod 16. A cutting groove 15 is opened on the upper end surface of the workbench 1, and a cutting knife 13 is slidably connected in the cutting groove 15;

[0042] The threaded rod 16 works to transmit force and can control the left and right movement of the fixed plate 17. At the same time, the cutting groove 15 makes the cutting knife 13 more stable and smooth when sliding inside;

[0043] The surface of the threaded rod 16 is threaded and penetrates the inner wall of the workbench 1, and the surface of the knob is fixedly connected with anti-slip grooves;

[0044] Equipped with anti-slip grooves to ensure stability when turning the knob;

[0045] There are two cutting grooves 15, each of which is provided with a cutting knife 13. The outer sides of the two cutting knives 13 are fixedly connected to one end of the connecting rod 12 respectively.

[0046] Working principle: When the copper clad laminate 2 is placed downward in the groove, the knob is used to control the threaded rod 16 to rotate clockwise, so that the threaded rod 16 controls the fixing plate 17 and the protective pad 18 to move toward the copper clad laminate 2. When one side of the protective pad 18 touches the surface of the copper clad laminate 2, the copper clad laminate 2 is clamped and limited, making the copper clad laminate 2 more stable in the workbench 1 and the laminating film more accurate during lamination.
