Description

[0001] This application is a divisional application of the application filed on May 13, 2025, with application number 202510608112.3 and invention name “A device for exposing an integrated circuit carrier PCB circuit board”. Technical Field

[0002] The present invention belongs to the technical field of exposure equipment, in particular to an exposure device for an integrated circuit carrier PCB board. Background Art

[0003] The integrated circuit carrier PCB circuit board is a high-precision printed circuit board designed specifically for carrying and connecting integrated circuit chips. It is mainly used in scenarios such as semiconductor packaging, chip testing, and system integration. It is a key carrier connecting chips and external circuits in the integrated circuit industry chain. Its design and process directly affect the electrical performance, reliability, and heat dissipation capacity of the chip. The essence of PCB board exposure is to transfer the mask pattern to the photosensitive material layer on the surface of the copper clad board through ultraviolet light irradiation, and use photochemical reaction to form an anti-etching pattern. The core step is to expose the photosensitive material layer that has been bonded or coated on the surface of the copper clad board to achieve the purpose of pattern transfer.

[0004] Photosensitive materials are generally divided into dry film and wet film. The bonding of dry film and copper clad laminate is a key process in PCB (printed circuit board) pattern transfer, which directly affects the subsequent exposure, development accuracy and circuit quality.

[0005] In the current existing technology, the bonding of dry film and copper clad laminate is a process in which the solid adhesive layer is melted and leveled by thermal action, and mechanical bite and intermolecular force are formed with the copper foil surface under the action of roller pressure. However, when the dry film and copper clad laminate are bonded by roller pressing, the main function of the roller is to apply pressure to help the dry film and copper plate fit tightly while expelling most of the air. However, bubbles will remain at the edges or corners. At this time, the remaining bubbles may affect the subsequent exposure and development steps, resulting in circuit defects.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7As shown, an integrated circuit carrier PCB board exposure device according to an embodiment of the present invention includes a housing 1, a placement plate 2 is provided inside the housing 1, a matching plate 8 is provided above the placement plate 2, a main rolling assembly 4 and a pre-rolling assembly 5 for rolling the PCB board and the dry film are configured inside the housing 1, and an adjustment assembly 6 for improving the bonding quality between the copper clad laminate and the dry film is configured between the main rolling assembly 4 and the pre-rolling assembly 5; The adjustment component 6 includes a two-way cylinder 601, and the left and right output ends of the two-way cylinder 601 are fixedly connected to the adjustment rod 602, one end of the adjustment rod 602 is rotatably connected to the cutting piece 603, and one side of the cutting piece 603 is splined to the driving motor 604, and the side of the cutting piece 603 close to the driving motor 604 is rotatably connected to the matching sleeve 607, and the surface of the matching sleeve 607 is fixedly connected to the arc rod 608, and one end of the arc rod 608 is fixedly connected to the limit bar 609, and a guide plate 613 is provided in front of the limit bar 609, and the guide plate 613 is rotatably connected to the matching plate 8 through a pin shaft, and a top spring is provided between the guide plate 613 and the limit bar 609.

[0023] The present invention takes into account that before exposing the integrated circuit carrier PCB circuit board, it is necessary to adhere a dry film to the surface of the copper clad board. When the copper clad board and the dry film are rolled, a large number of bubbles may be generated between the copper clad board and the dry film. Although most of the bubbles can be expelled by the pre-rolling of the pre-rolling component 5 and the formal rolling of the main rolling component 4, bubbles may remain at the edge. At this time, the residual bubbles may affect the subsequent exposure and development steps, resulting in circuit defects and reducing the quality of exposure of the integrated circuit carrier PCB circuit board. In addition, since the size of the dry film adhered to the surface of the copper clad board is larger than the size of the board itself and has a certain viscosity, when the dry film is placed on the surface of the copper clad board, there will be residual dry film extending from the edge positions on both sides of the copper clad board. When the dry film and the copper clad board are rolled and adhered, in order to ensure the accuracy of the bonding position, it is generally necessary to The sides of the plate are limited, but after the plate and the film are limited, the remaining dry film will stick to the sides of the copper clad plate. When the dry film and the copper clad plate are rolled to expel bubbles, the two sides of the plate are equivalent to being "sealed" by the dry film. At this time, the bubbles cannot be quickly expelled from the two sides of the plate in time, resulting in a large number of bubbles remaining in a small state between the copper clad plate and the dry film after the formal rolling, affecting the quality of subsequent exposure and development. Therefore, first, the two-way cylinder 601 is started to drive the adjusting rod 602 to move telescopically through the output end. The movement of the adjusting rod 602 can drive the cutting piece 603 to move inside the matching plate 8, thereby adjusting the position of the cutting piece 603, and then the copper clad plate and the dry film are placed on the top of the placement plate 2, so that the two sides are inserted into the sliding grooves opened inside the matching plate 8, which can limit the two sides of the plate and the film, making it convenient for the two to be rolled and bonded; During operation, after the plate and film are inserted into the slide groove inside the matching plate 8, the pre-rolling assembly 5 is started to transport the film and plate, and the driving motor 604 is started to drive the cutting piece 603 that has been adjusted to rotate. When the film passes the position of the cutting piece 603, the cutting piece 603 can cut the remaining position of the edge of the dry film to avoid the bubbles from being discharged in time when the film and plate are rolled subsequently. It should be noted that when the cutting piece 603 is adjusting its position, the cutting piece 603 will drive the matching sleeve 607 and the arc rod 608 to move. The movement of the arc rod 608 can drive the limiting bar 609 to move inside the matching plate 8. When one side of the film is being cut, if the film accumulates more and more inside the matching plate 8 at this time, when the cut film accumulates to a certain extent, it will be entangled. The edge of the film is cut, and the edge of the cut film will continue to move backward along the inner side of the cone tip of the limiting strip 609. At the same time, the limiting strip 609 can "diverge" the cut film and the film to be rolled, so as to prevent the cut film from affecting the accuracy of the position of the uncut film on the surface of the copper clad board. Moreover, since the edge of the film has been cut, when the film continues to move backward, the edge of the film will always be in contact with the inner side of the limiting strip 609, thereby improving the stability of the film on the surface of the board and avoiding the position deviation of the film and the copper clad board during the rolling process. It should be noted again that, by providing a discharge groove inside the matching plate 8, since the dry film has a certain hardness before being rolled, after the film is cut, the cut film will first contact one side of the guide plate 613, and then be guided by the surface of the guide plate 613 to the inside of the discharge groove and discharged from the discharge groove, which can prevent the cut film from accumulating inside the matching plate 8 and affecting the normal cutting of the film by the cutting piece 603. In addition, since a top spring is provided between the guide plate 613 and the limit bar 609, when the limit bar 609 is adjusted in position inside the matching plate 8 After adjustment, one end of the top spring will be driven to move. After one end of the top spring is forced to move, the other end will apply pressure to or release pressure on the guide plate 613. When the remaining dry film is cut to a wider size, the limit strip 609 will be closer to the position of the film inside the matching plate 8, and under the action of the tension spring, the angle between the guide plate 613 and the matching plate 8 will be larger, which is convenient for guiding the cut film and discharging the film from the discharge groove. It can effectively improve the effect of discharging bubbles when the dry film and the copper clad laminate are rolled, thereby improving the subsequent exposure and development of the copper clad laminate.

[0024] like Figures 8 to 10As shown, the surface of the adjusting rod 602 is fixedly connected to the fixed cylinder 605, the front of the fixed cylinder 605 is slidably engaged with the engaging rod 606, the surface of the engaging rod 606 is slidably connected to the top plate 9, the upper end of the engaging rod 606 is fixedly connected to the transmission plate 611, the front end of the transmission plate 611 is fixedly connected to the connecting rod 10, the lower part of the connecting rod 10 is rotatably connected to the rotating sleeve 11, the interior of the rotating sleeve 11 is fixedly connected to the second extrusion roller 502, and the surface of the connecting rod 10 is slidably connected to the connecting plate 12.

[0025] The present invention also takes into account that when dry films of different sizes are cut to remain, although the size of the dry film edge can be adjusted by adjusting the cutting position of the cutting piece 603, when the cutting size becomes larger, due to the increase in the size of the film, the contact area between the film and the plate becomes larger, and bubbles are more likely to be generated at this time. If the force of the second squeezing roller 502 for pre-rolling the film is not changed, the effect of the pre-rolling will be reduced, not only causing an increase in the number of bubbles at the edge, but also excessive bubbles in the middle position will remain before the formal squeezing. Therefore, by arranging a pre-rolling assembly 5 inside the shell 1, when the film and the plate are inserted into both sides of the matching plate 8 and conveyed to the rear by the pre-rolling assembly 5, the plate and the film will move from under the second squeezing roller 502. At this time, the second squeezing roller 502 can rotate to pre-roll the film and the plate, and can squeeze out most of the bubbles before the film and the plate are formally rolled, thereby improving the quality of the formal rolling. It should be noted that when the size of the film increases, in order to prevent the two sides of the film from being fully fitted with the two sides of the plate during formal rolling, the amount required to be reserved on both sides of the film will also increase. At this time, the two-way cylinder 601 is started to drive the cutting piece 603 at one end of the adjusting rod 602 to move outward. At this time, the movement of the adjusting rod 602 will drive the fixed cylinder 605 to move. The movement of the fixed cylinder 605 can cooperate with the inclined groove inside the matching rod 606 through the internal inclined block. When the fixed cylinder 605 moves outward, the fixed cylinder 605 can drive the matching rod 606 to move downward inside the top plate 9 through the inclined block. The downward movement of the matching rod 606 can drive the upper transmission plate 611 to move. The movement of the transmission plate 611 can electrically move the rotating sleeve 11 under the connecting rod 10. At this time, the movement of the rotating sleeve 11 can drive the second squeezing roller 502 to press down on the top of the film, thereby increasing the force of the second squeezing roller 502 on the pre-rolling of the film, thereby improving the effect of pre-rolling the film, and avoiding a large number of bubbles remaining during formal rolling that ultimately affect the quality after the lamination is completed. It should be noted again that, since the position of the cutting piece 603 inside the matching plate 8 is only slightly adjusted, the fixed cylinder 605 pushes the matching rod 606 up and down through the inclined block, which is also a "short distance" movement, and the matching rod 606 will not drive the transmission plate 611 to move a long distance. This can effectively prevent the second squeezing roller 502 from applying a large pressure on the film, thereby affecting the effect of pre-rolling between the film and the plate and causing damage to the film itself. In addition, when cutting a film of smaller size, it is necessary to move the cutting piece 603 to the middle position. At this time, the pressure of the second squeezing roller 502 on the film will be reduced. Since the contact area between the film and the plate becomes smaller, the bubble generation rate will be reduced. At this time, no large force is required to easily squeeze out the bubbles, which can effectively improve the effect of pre-rolling. The adjustment component 6 and the pre-rolling component 5 are linked. When performing residual cutting of films of different sizes, the force used for pre-rolling of the film can be accurately controlled, thereby fully improving the bonding effect between the film and the plate and improving the quality of subsequent exposure and development.

[0026] like Figures 2 to 3 As shown, the main rolling assembly 4 includes a first conveyor roller 401, and a first squeezing roller 402 is arranged below the first conveyor roller 401. A cooling machine 3 is arranged behind the main rolling assembly 4 for cooling the film and copper clad laminate after roller pressing and lamination. The pre-rolling assembly 5 includes a second conveyor roller 501, and the second conveyor roller 501 is arranged directly below the second squeezing roller 502.

[0027] During operation, after the film and the plate are inserted into the interior of the matching plate 8, the second conveying roller 501 is driven by the motor to rotate to convey the plate, thereby driving the film to move below the second squeezing roller 502 to achieve pre-rolling of the film and the plate, and when the pre-rolling is completed, the second conveying roller 501 rotates and continues to convey to convey the plate to the top of the first conveying roller 401. At this time, the first conveying roller 401 is driven by the motor to rotate to continue conveying the plate and the film, and at this time, the first squeezing roller 402 will also rotate under the drive of the motor. At this time, the film and the plate can complete the roll-pressing and bonding work under the coordinated rotation of the first conveying roller 401 and the first squeezing roller 402, which can effectively improve the bonding efficiency between the two. After the roll-pressing is completed, the first conveying roller 401 will continue to drive the film and the plate after rolling to continue to move backward. At this time, the cooling machine 3 is started to generate cold air to cool it down, which can improve the efficiency of subsequent exposure and development.

[0028] like Figures 11 to 14As shown, the middle position of the transmission plate 611 is provided with a scraping assembly 7 for scraping off the bubbles remaining on the edge after pre-rolling. The scraping assembly 7 includes a moving rod 701. The surface of the moving rod 701 is fixedly connected to a cylindrical cam 702. An arc groove is provided on the surface of the cylindrical cam 702. A sliding column 704 is slidingly provided inside the arc groove. One end of the sliding column 704 is fixedly connected to a fixed sleeve 703. The fixed sleeve 703 is fixedly connected to the transmission plate 611. The lower end of the moving rod 701 is detachably connected to a scraper 707.

[0029] The present invention fully takes into account that after the film and the plate are pre-rolled, in order to prevent certain bubbles from remaining in the middle of the film when the second squeezing roller 502 is rolled after the film is completely covered, the second squeezing roller 502 is set to be slightly shorter than the width of the film, so that the middle position of the film can be fully squeezed to prevent bubbles from remaining in the middle position of the film. However, after the middle of the film is squeezed, certain bubbles will still remain at the edges of both sides of the film below the second squeezing roller 502 and cannot be discharged. Even after the remaining position of the film is cut, when the film and the plate are formally rolled, the bubbles may not be completely squeezed out, and thus remain at the edge positions of the plate and the film. Therefore, by arranging two sets of inclined scrapers 707 behind the second squeezing roller 502, after the second squeezing roller 502 has fully squeezed and discharged the middle position of the film, the two sets of scrapers 707 can continue to scrape out the bubbles at the edge positions, thereby improving the effect of discharging bubbles between the film and the plate. It should be noted that, when rolling a film of a larger size, due to the larger width of the film, more bubbles may remain on the edge after the second squeezing roller 502 is rolled. Therefore, when the transmission plate 611 adjusts the pressure value of the second squeezing roller 502 through the connecting rod 10 and the rotating sleeve 11, the downward movement of the transmission plate 611 will drive the fixed sleeve 703 to move downward, and the movement of the fixed sleeve 703 will drive the sliding column 704 to move downward. At this time, one end of the sliding column 704 will slide inside the arc groove opened on the surface of the cylindrical cam 702, thereby causing the cylindrical cam 702 and the moving rod 701 to rotate. The rotation of the moving rod 701 can drive the scraper 707 to rotate, and the position of the scraper 707 is adjusted to make it tend to a "horizontal" state. When scraping bubbles from the edge of a film of a larger size, a large number of bubbles can be avoided from remaining at the edge of the film and the plate, thereby improving the effect of scraping the film. It should be noted again that by changing the rolling pressure of the second squeezing roller 502 and adjusting the angle of the scraper 707 at the same time, it is possible to process the edge bubbles of films with different widths after pre-rolling, thereby improving the overall bubble processing effect between the film and the plate, and when the angle of the scraper 707 is adjusted, the bottom surface of the scraper 707 and the surface of the film will tend to be "parallel", so while scraping off the bubbles, the film can be positioned, which not only facilitates the stability of the cutting piece 603 when cutting the remaining position of the film, but also drives the bubbles to the edge position of the film and the plate. The remaining bubbles will lift the film adhered to both sides of the plate to a certain extent, making it convenient for the cutting piece 603 to cut the film. At this time, the cutting of the cutting piece 603 will not only assist in the discharge of bubbles, but also effectively improve the rapid discharge of bubbles from the edge of the cut film after the formal rolling of the film, which can effectively improve the quality of the bonding between the film and the plate.

[0030] like Figures 13 and 14 As shown, the surface of the movable rod 701 is fixedly connected to the rotating ring 705, the surface of the rotating ring 705 is rotatably connected to the limiting ring 706, the surface of the limiting ring 706 is rotatably connected to the first incomplete rack 708 through a pin shaft, the surface of the first incomplete rack 708 is meshedly connected to the incomplete gear 709, the incomplete gear 709 is meshedly connected to the second incomplete rack 711, the surface of the matching rod 606 below the transmission plate 611 is fixedly connected to the fixing ring 612, the surface of the fixing ring 612 is fixedly connected to the wedge block 610, and the surfaces of the second incomplete rack 711 and the first incomplete rack 708 are slidably connected to the working bin 710.

[0031] During operation, when the scraper 707 is adjusted in angle to scrape bubbles off the edges of films of different widths, if the scraper 707 is directly rotated and adjusted, the film contacted by the lower end of the scraper 707 will be "rubbed", causing wrinkles on the surface of the film and affecting the quality of the overall bonding between the film and the plate. Therefore, a rotating ring 705 and a limiting ring 706 are provided on the surface of the movable rod 701. When the matching rod 606 moves downward to adjust the second squeezing roller 502 and the scraper 707, the movement of the matching rod 606 will drive the fixed ring 612 to move, and the movement of the fixed ring 612 can drive the wedge 610 to move. At this time, the movement of the wedge 610 will push the second squeezing roller 502 and the second squeezing roller 502 through its inclined surface. The incomplete rack 711 slides inside the working chamber 710. The sliding of the second incomplete rack 711 at this time can mesh with the transmission to drive the incomplete gear 709 to rotate. The rotation of the incomplete gear 709 can mesh with the transmission to drive the first incomplete rack 708 to rotate. The rotation of the first incomplete rack 708 can drive the limiting ring 706 to move upward through the hinge plate. The upward movement of the limiting ring 706 can drive the rotating ring 705 inside it to move. The rotating ring 705 can drive the scraper 707 below to move upward a short distance through the moving rod 701, so that the scraper 707 loses contact with the film during rotation, thereby avoiding damage to the film and affecting the overall bonding quality between the film and the plate. The scraper 707 is reset after the scraper 707 is reset and the matching rod 606 is reset upward. At this time, the scraper 707 will also rotate in the opposite direction and lose contact with the film, thereby effectively improving the stability of the film during lamination and improving the overall lamination quality of the film and the plate. It should be further explained that when the first incomplete rack 708 drives the scraper 707 to move up and down through the hinged plate, the transmission plate 611 drives the cutting piece 603 to move in coordination with the scraper 707. At this time, the scraper 707 will move upward and rotate rapidly, which can improve the conversion speed when scraping bubbles from films of different widths, effectively protect the film, and improve the efficiency of bubble discharge.

[0032] like Figures 4 to 6As shown, the bidirectional cylinder 601 and the top plate 9 are fixedly connected, a spring is provided between the mating rod 606 and the top plate 9, the two ends of the top plate 9 are fixedly connected with a cutting chamber, and the cutting chamber is fixedly arranged above the mating plate 8, and the bidirectional cylinder 601 drives the cutting piece 603 to adjust its position inside the cutting chamber through the adjusting rod 602.

[0033] During operation, when the adjusting rod 602 drives the matching rod 606 to move up and down through the inclined plate inside the fixed cylinder 605, a spring is provided at the sliding position of the matching rod 606 and the top plate 9. When the matching rod 606 moves downward, the spring is continuously squeezed. At this time, the rebound force of the spring and the friction between the inclined plate inside the fixed cylinder 605 and the inclined groove inside the matching rod 606 can effectively improve the stability of the matching rod 606 after being pressed down, thereby improving the stability of the pressure adjustment of the second squeezing roller 502. It should be noted that when the position of the cutting piece 603 is adjusted, the two sets of fixed cylinders 605 will move relative to each other, and since the inclination directions of the internal inclined plates are different, the fixed cylinders 605 can simultaneously drive the matching rod 606 to move up and down through the inclined plates when they move relative to each other, so that the force transmitted from the transmission plate 611 to the connecting rod 10 and the rotating sleeve 11 can be in a uniform state, and the force of the second squeezing roller 502 to pre-roll the film can be changed in a smooth state, thereby improving the rolling of the position between the film and the plate, and fully discharging the bubbles from the middle.

[0034] like Figure 13 As shown, the upper end of the moving rod 701 is rotatably connected to the housing 1, and the fixed sleeve 703 is sleeved on the outside of the cylindrical cam 702. The fixed sleeve 703 drives the cylindrical cam 702 and the moving rod 701 to rotate through the sliding column 704. The scraper 707 is made of silicone or rubber material.

[0035] During operation, since the contact surface between the wedge block 610 and the second incomplete rack 711 is set to a certain arc, when the wedge block 610 moves downward, it will first push the second incomplete rack 711 to slide inside the working chamber 710 through the inclined surface, which can quickly drive the moving rod 701 to move upward. Since one end of the sliding post 704 slides inside the arc groove on the surface of the cylindrical cam 702, at this time, before the cylindrical cam 702 rotates, the wedge block 610 has pushed the moving rod 701 upward through the inclined surface. When the sliding post 704 slides a certain distance in the sliding groove inside the cylindrical cam 702, the scraper 707 that has been "lifted" will rotate. This can effectively prevent the scraper 707 from rotating first and then causing damage to the film, thereby affecting the quality of the overall bonding between the film and the plate. It should be noted that since the second incomplete rack 711 and the first incomplete rack 708 are both sliding inside the working chamber 710, when the wedge block 610 loses the squeezing force on the second incomplete rack 711, the scraper 707 and the moving rod 701 will push the first incomplete rack 708 in the opposite direction to slide inside the working chamber 710 under the action of gravity, and since the rotating ring 705 and the limiting ring 706 are rotatably connected, when the limiting ring 706 moves downward, it will first drive the hinged plate to move, and only after the hinged plate moves will it drive the first incomplete rack 708 to slide in the opposite direction, which can prevent the scraper 707 from instantly falling and hitting the surface of the membrane after losing the thrust of the wedge block 610 on the second incomplete rack 711, causing damage to the membrane, and can further improve the protection of the membrane.

[0036] like Figures 6 to 9 As shown, the matching sleeve 607 and the adjusting rod 602 are both rotatably connected to the output end of the driving motor 604. The adjusting rod 602 drives the cutting piece 603 to move inside the cutting chamber. The cutting piece 603 drives the limiting strip 609 at one end of the arc rod 608 to slide inside the matching plate 8 through the matching sleeve 607. A cutting groove that passes through the interior of the cutting chamber is opened inside the matching plate 8 at the position of the cutting piece 603.

[0037] During operation, since the adjusting rod 602 is slidably connected to the matching plate 8, and one end thereof is fixedly connected to an output end of the two-way cylinder 601, when the two-way cylinder 601 adjusts the position of the cutting piece 603, the inner side of the limiting strip 609 moves inside the matching plate 8 and is in close contact with the side surface of the cut dry film. At the same time, since one end of the guide plate 613 and one end of the limiting strip 609 are both tapered, the cut film can be fully guided to be discharged through the discharge chute, and it can be ensured that the cut film can be accurately guided by the limiting strip 609. It should be noted that when the cutting piece 603 moves inside the cutting chamber, since the output end of the cutting piece 603 and the driving motor 604 are splined, even if the cutting piece 603 moves, it will not affect the driving motor 604 to drive it to rotate, and the edge of the film can be cut stably. At the same time, after the cutting is completed, the scraper 707 can be "driven" to the edge to release the bubbles, which can effectively prevent bubbles from remaining at the edge of the film and the board, affecting the overall bonding quality, and improving the quality of subsequent exposure of the PCB board.

[0038] like Figures 4 and 5 As shown, the adjusting rod 602 and the matching sleeve 607 are both mounted on the output end surface of the driving motor 604. The driving motor 604 is fixedly connected to the matching plate 8. The adjusting rod 602 is slidably connected to the cutting chamber. The interior of the matching plate 8 is provided with a stepped groove for placing the copper clad plate and the dry film.

[0039] During operation, when the film and the plate are placed inside the matching plate 8, since the matching plate 8 has a stepped groove inside for placing the copper-clad plate and the dry film, the plate is first inserted into the stepped groove below, and after limiting the two sides of the plate, the film is inserted above the matching plate 8 to make the film and the plate fit tightly together. This can ensure the accuracy of the position of the two during pre-rolling and formal rolling, avoid the position deviation of the film during the rolling process, and effectively improve the effect of the film fitting on the plate surface.

[0040] like Figure 9 and Figure 11 As shown, the mating rod 606 drives the wedge block 610 to move up and down through the fixed ring 612. The surface of the wedge block 610 is set at a certain arc. The wedge block 610 is made of wear-resistant material. The inclination angle of the inclined plate inside the fixed cylinder 605 is consistent with the inclination angle of the inclined groove opened inside the mating rod 606. The connecting plate 12 and the mating plate 8 are fixedly connected.

[0041] During operation, the contact between the wedge block 610 and the second incomplete rack 711 can push it to slide inside the working chamber 710, which can effectively adjust the up and down movement of the scraper 707, improve the protection effect of the film, and avoid damage to the surface of the film. In addition, since the inclination angle of the inclined plate inside the fixed cylinder 605 is consistent with the inclination angle of the inclined groove opened inside the matching rod 606, when the fixed cylinder 605 drives the matching rod 606 to move up and down and needs to be stabilized, the matching of the inclined surface can avoid the matching rod 606 from falling off after being "lifted", which can effectively improve the stability after pressure is applied to the second squeezing roller 502, thereby facilitating the squeezing of the middle part of the film and the plate, thereby improving the exposure quality of the PCB board in the integrated circuit.
