Description

Technical Field

[0001] The present invention belongs to the technical field of exposure equipment, and specifically relates to an exposure device for an integrated circuit carrier PCB circuit board. Background Art

[0002] An integrated circuit carrier PCB circuit board is a high-precision printed circuit board designed specifically for carrying and connecting integrated circuit chips, and 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 industrial chain, and its design and process directly affect the electrical performance, reliability, and heat dissipation ability of the chips. The essence of PCB board exposure is to transfer the mask pattern to the photosensitive material layer on the surface of the copper clad laminate through ultraviolet light irradiation, and form an anti-etching pattern through a photochemical reaction. The core step is to expose the photosensitive material layer that has been adhered or coated on the surface of the copper clad laminate to achieve the purpose of pattern transfer.

[0003] Photosensitive materials are generally divided into dry film and wet film. Among them, the lamination of the dry film and the copper clad laminate is a key process for PCB (printed circuit board) pattern transfer, which directly affects the accuracy of subsequent exposure and development and the quality of the circuit.

[0004] In the current prior art, the lamination of the dry film and the 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 on the surface of the copper foil under the action of the roller pressure. However, when the dry film and the copper clad laminate are laminated by the rolling method, the main function of the roller at this time is to apply pressure to help the dry film and the copper plate fit tightly, and at the same time discharge most of the air. However, bubbles will remain in the edges or corners. At this time, the remaining bubbles may affect the subsequent exposure and development steps, resulting in circuit defects. Therefore, the present invention provides an exposure device for an integrated circuit carrier PCB circuit board. Summary of the Invention

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0021] As Figures 1 to 7As shown in the figure, an exposure device for an integrated circuit carrier PCB circuit board according to an embodiment of the present invention includes a housing 1. Inside the housing 1, a placement board 2 is provided. Above the placement board 2, a mating board 8 is provided. Inside the housing 1, a main rolling component 4 and a pre-rolling component 5 for rolling the PCB board and the dry film are configured. An adjusting component 6 for improving the bonding quality of the copper clad laminate and the dry film is configured between the main rolling component 4 and the pre-rolling component 5; The adjusting component 6 includes a bidirectional cylinder 601. The output ends on the left and right sides of the bidirectional cylinder 601 are fixedly connected with adjusting rods 602. One end of the adjusting rod 602 is rotatably clamped with a cutting piece 603. One side of the cutting piece 603 is spline-connected with a driving motor 604. One side of the cutting piece 603 close to the driving motor 604 is rotatably clamped with a mating sleeve 607. The surface of the mating sleeve 607 is fixedly connected with an arc rod 608. One end of the arc rod 608 is fixedly connected with a limiting strip 609. In front of the limiting strip 609, a guiding plate 613 is provided. The guiding plate 613 is rotatably connected to the mating board 8 through a pin shaft, and a top spring is provided between the guiding plate 613 and the limiting strip 609.

[0022] The present invention considers that before exposing the integrated circuit carrier PCB circuit board, it is necessary to bond the dry film to the surface of the copper clad laminate. When rolling the copper clad laminate and the dry film, a large number of bubbles may be generated between the copper clad laminate and the dry film. Although most of the bubbles can be discharged through 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 positions. These remaining bubbles may affect the subsequent exposure and development steps, resulting in circuit defects and reducing the quality of the integrated circuit carrier PCB circuit board exposure. Moreover, since the size of the dry film bonded to the surface of the copper clad laminate 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 laminate, the edge positions on both sides of the copper clad laminate will have the remaining dry film protruding. When rolling and bonding the dry film and the copper clad laminate, in order to ensure the accuracy of the bonding position, the sides of the board are generally limited. However, after limiting between the board and the film, the remaining dry film will stick to the sides of the copper clad laminate. When rolling and discharging the bubbles between the dry film and the copper clad laminate, the two sides of the board are equivalent to being "sealed" by the dry film. At this time, the bubbles cannot be quickly discharged from the two sides of the board in time, resulting in a large number of bubbles remaining between the copper clad laminate and the dry film in a small state after the formal rolling, affecting the quality of subsequent exposure and development. Therefore, first start the bidirectional cylinder 601 to drive the adjusting rod 602 to perform telescopic movement through the output end. The movement of the adjusting rod 602 can drive the cutting piece 603 to move inside the mating board 8, so as to adjust the position of the cutting piece 603. Then, place the copper clad laminate and the dry film above the placement board 2, and insert the two sides into the sliding grooves opened inside the mating board 8, which can limit the two sides of the board and the film, facilitating the rolling and bonding of the two; During operation, after the plate and the film are inserted into the chute inside the mating plate 8, the pre-roll pressing assembly 5 is started to convey the film and the plate. At the same time, the driving motor 604 is started to drive the cutting piece 603 with the adjusted position to rotate. When the film passes through the position of the cutting piece 603, the cutting piece 603 can cut the remaining position of the edge of the dry film, avoiding the situation that air bubbles are not discharged in time during the subsequent rolling of the film and the plate. It should be noted that when the cutting piece 603 is adjusting its position, the cutting piece 603 will drive the mating sleeve 607 and the arc rod 608 to move. The movement of the arc rod 608 can drive the limiting strip 609 to move inside the mating plate 8. When one side of the film is being cut, if the film accumulates more and more inside the mating plate 8 at this time, when the cut film accumulates to a certain extent, it will wind around the surface of the cutting piece 603, which not only affects the normal cutting of the cutting piece 603, but also affects the position accuracy of the film on the surface of the plate. At this time, the end of the limiting strip 609 close to the cutting piece 603 is set to be conical. After the edge of the film is cut, the edge of the cut film will continue to move backward along the inner side of the tip of the limiting strip 609. At the same time, the limiting strip 609 can perform a "shunting" operation on the cut film and the film to be rolled, preventing the cut film from affecting the position accuracy of the uncut film on the surface of the copper clad laminate. And because the edge of the film has been cut at this time, 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 plate and avoiding the situation of position deviation between the film and the copper clad laminate during the rolling process; It should be noted again that by providing a discharge groove inside the mating 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 guiding plate 613 and is guided by the surface of the guiding plate 613 into the inside of the discharge groove and discharged from the discharge groove, which can avoid the cut film accumulating inside the mating plate 8 and affecting the normal cutting of the cutting piece 603 on the film. And because a top spring is provided between the guiding plate 613 and the limiting strip 609, when the limiting strip 609 adjusts its position inside the mating plate 8, one end of the top spring will be driven to move at this time. After one end of the top spring is stressed and moves, the other end will apply pressure or release pressure to the guiding plate 613. When the remaining cut of the dry film is of a relatively wide size, at this time, the limiting strip 609 will move closer to the position of the film inside the mating plate 8, and under the action of the tension spring, the angle between the guiding plate 613 and the mating plate 8 will be larger, which is convenient for guiding the cut film and enabling the film to be discharged from the discharge groove, effectively improving the effect of air bubble discharge when the dry film and the copper clad laminate are rolled, thereby improving the subsequent exposure and development effects of the copper clad laminate.

[0023] As Figures 8 to 10As shown in the figure, a fixed cylinder 605 is fixedly connected to the surface of the adjusting rod 602. A mating rod 606 is slidably fitted in front of the fixed cylinder 605. A top plate 9 is slidably connected to the surface of the mating rod 606. A transmission plate 611 is fixedly connected to the upper end of the mating rod 606. A connecting rod 10 is fixedly connected to the front end of the transmission plate 611. A rotating sleeve 11 is rotatably connected below the connecting rod 10. A second pressing roller 502 is fixedly connected to the inside of the rotating sleeve 11. A connecting plate 12 is slidably connected to the surface of the connecting rod 10.

[0024] The present invention also takes into account that when performing remaining cutting on dry films of different sizes, although the size of the cut on the edge of the dry film 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 at this time, bubbles are more likely to be generated. If the force of the second pressing roller 502 for pre-rolling the film is not changed, the pre-rolling effect will be reduced at this time, which will not only cause an increase in edge bubbles, but also excessive bubbles will remain in the middle position before the formal pressing. Therefore, by providing a pre-rolling assembly 5 inside the housing 1, when the film and the plate are inserted into both sides of the mating plate 8 and are conveyed to the rear by the pre-rolling assembly 5, at this time, the plate and the film will move from below the second pressing roller 502. At this time, the rotation of the second pressing roller 502 can pre-roll the film and the plate, and most of the bubbles can be squeezed out before the formal rolling of the film and the plate, improving the quality of the formal rolling. It should be noted that when the size of the film increases, in order to avoid the two sides of the film not fully fitting with the two sides of the plate during the formal rolling, the amount to be reserved on both sides of the film will also increase at this time. At this time, the bidirectional cylinder 601 is started to drive the cutting piece 603 at one end of the adjusting rod 602 to move outwards. 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 mating rod 606 through the inclined block inside. When the fixed cylinder 605 moves outwards, at this time, the fixed cylinder 605 can drive the mating rod 606 to move downwards inside the top plate 9 through the inclined block. The downward movement of the mating rod 606 can drive the upper transmission plate 611 to move. The movement of the transmission plate 611 can drive the rotating sleeve 11 below the electric connecting rod 10 to move. At this time, the movement of the rotating sleeve 11 can drive the second pressing roller 502 to press down above the film, thereby increasing the force of the second pressing roller 502 for pre-rolling the film, and thus improving the pre-rolling effect on the film, and avoiding a large number of remaining bubbles ultimately affecting the quality after the fitting is completed during the formal rolling. It should be noted again that since the position of the cutting piece 603 inside the mating plate 8 is only slightly adjusted, the fixed cylinder 605 pushes the mating rod 606 to move up and down through the inclined block, which is also a "short-distance" movement. It will not cause the mating rod 606 to drive the transmission plate 611 to move a long distance, effectively avoiding the second pressing roller 502 applying a large pressure to the film, thereby affecting the pre-rolling effect between the film and the plate and damaging the film itself. And when cutting a film with a smaller size, at this time, the cutting piece 603 needs to be moved towards the middle position. At this time, the pressure of the second pressing roller 502 on the film will decrease. Since the contact area between the film and the plate becomes smaller, the bubble generation rate will decrease. At this time, the bubbles can be easily squeezed out without the need for a large force, effectively improving the pre-rolling effect, enabling the adjustment component 6 and the pre-rolling component 5 to be linked. When performing remaining cutting on films of different sizes, the force used for pre-rolling the film can be accurately controlled, thereby fully improving the fitting effect between the film and the plate and improving the quality of subsequent exposure and development.

[0025] As Figures 2 to 3 shown, the main rolling component 4 includes a first conveying roller 401. A first pressing roller 402 is arranged below the first conveying roller 401. A cooler 3 for cooling the film and the copper clad laminate after rolling and fitting is arranged behind the main rolling component 4. The pre-rolling component 5 includes a second conveying roller 501, and the second conveying roller 501 is arranged directly below the second pressing roller 502.

[0026] During operation, when the film and the plate are inserted into the inside of the mating plate 8, at this time, the motor drives the second conveying roller 501 to rotate to convey the lower part of the plate, thereby driving the film to move below the second pressing roller 502 to realize the pre-rolling of the film and the plate. And when the pre-rolling is completed, at this time, the second conveying roller 501 rotates and continues to convey to send the plate above the first conveying roller 401. At this time, the motor drives the first conveying roller 401 to rotate to continue conveying the plate and the film. And at this time, the first pressing roller 402 also rotates driven by the motor. At this time, under the combined rotation of the first conveying roller 401 and the first pressing roller 402, the plate and the film can complete the rolling and fitting work, effectively improving the fitting efficiency between the two. When the rolling and fitting is completed, the first conveying roller 401 will continue to drive the rolled film and plate to move backward. At this time, the cooler 3 is started to generate cold air for cooling treatment, which can improve the working efficiency of subsequent exposure and development.

[0027] As Figures 11 to 14As shown in the figure, a scraping assembly 7 for scraping the residual bubbles at the edge after pre-rolling is arranged at the middle position of the transmission plate 611. The scraping assembly 7 includes a moving rod 701. A cylindrical cam 702 is fixedly connected to the surface of the moving rod 701. An arc groove is formed on the surface of the cylindrical cam 702. A sliding column 704 is slidably arranged 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 scraping plate 707.

[0028] The present invention fully considers that after the film and the plate are pre-rolled, in order to avoid residual bubbles in the middle of the film when the second pressing roller 502 completely covers the film and then rolls it, the second pressing roller 502 is set to be slightly shorter than the width of the film, which can fully press the middle position of the film and avoid residual bubbles in the middle position of the film. However, after the middle of the film is pressed, there will still be some bubbles remaining on the edges of both sides of the film under the second pressing roller 502 that cannot be discharged. Even after cutting the remaining position of the film, when the film and the plate are officially rolled, the bubbles may not be completely pressed out, so they will remain at the edge positions of the plate and the film. Therefore, by arranging two sets of inclined scraping plates 707 behind the second pressing roller 502, after the second pressing roller 502 fully presses and discharges the middle position of the film, the two sets of scraping plates 707 can continue to scrape the bubbles at the edge positions, which can improve the effect of discharging the bubbles between the film and the plate. It should be noted that after rolling a film with a large size, due to the large width of the film, there may be more residual bubbles at the edge after the second pressing roller 502 rolls. Therefore, when the transmission plate 611 adjusts the pressure value of the second pressing 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. The movement of the fixed sleeve 703 drives the sliding column 704 to move downward. At this time, one end of the sliding column 704 will slide inside the arc groove formed on the surface of the cylindrical cam 702, so that the cylindrical cam 702 and the moving rod 701 rotate. The rotation of the moving rod 701 can drive the scraping plate 707 to rotate and adjust the position of the scraping plate 707 to make it tend to a "horizontal" state, which can avoid a large amount of bubbles remaining at the edge positions of the film and the plate when scraping the edge bubbles of a film with a large size and improve the scraping effect on the film. It should be noted again that by changing the roll pressure of the second pressing roller 502 and adjusting the angle of the squeegee 707 at the same time, the edge bubble treatment after pre-rolling the film with different widths can be carried out, so as to improve the overall bubble treatment effect between the film and the plate. And when the angle of the squeegee 707 is adjusted, the bottom surface of the squeegee 707 and the surface of the film will tend to be in a "parallel" state at this time. Therefore, when scraping 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 after driving the bubbles to the edge positions of the film and the plate, the remaining bubbles will lift the film adhered to both sides of the plate to a certain extent, facilitating the cutting piece 603 to cut the film. At this time, the cutting of the cutting piece 603 will not only assist in discharging the bubbles, but also effectively improve the rapid discharge of the bubbles from the edge of the cut film after the film is officially rolled, and can effectively improve the bonding quality of the film and the plate.

[0029] As Figures 13 to 14 shown, a rotating ring 705 is fixedly connected to the surface of the moving rod 701, a limiting ring 706 is rotatably connected to the surface of the rotating ring 705, a first incomplete rack 708 is rotatably connected to the surface of the limiting ring 706 through a pin shaft, an incomplete gear 709 is meshed with the surface of the first incomplete rack 708, the incomplete gear 709 is meshed with a second incomplete rack 711, a fixed ring 612 is fixedly connected to the surface of the matching rod 606 below the transmission plate 611, a wedge block 610 is fixedly connected to the surface of the fixed ring 612, and a working bin 710 is slidably connected to the surfaces of the second incomplete rack 711 and the first incomplete rack 708.

[0030] During operation, when the squeegee 707 adjusts its angle to scrape bubbles from the edges of films with different widths, if the squeegee 707 is directly rotated for adjustment at this time, it will "rub" the film contacted by the lower end of the squeegee 707, causing wrinkles on the surface of the film and affecting the quality of the overall fit between the film and the plate. Therefore, a rotating ring 705 and a limiting ring 706 are provided on the surface of the moving rod 701. When the cooperating rod 606 moves downward to adjust the second squeezing roller 502 and the squeegee 707, the movement of the cooperating rod 606 at this time will drive the fixed ring 612 to move. The movement of the fixed ring 612 can drive the wedge block 610 to move. At this time, the movement of the wedge block 610 will push the second incomplete rack 711 to slide inside the working chamber 710 through its inclined surface. The sliding of the second incomplete rack 711 at this time can engage and drive the incomplete gear 709 to rotate. The rotation of the incomplete gear 709 can engage and 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 lower squeegee 707 to move upward a small distance through the moving rod 701, so that the squeegee 707 loses contact with the film during rotation, avoiding damage to the film and affecting the quality of the overall fit between the film and the plate; It should be noted that after the angle of the squeegee 707 is adjusted by rotating it upward, the upward movement of the moving rod 701 at this time can drive the cylindrical cam 702 and the downward sliding column 704 to move towards each other, which can shorten the sliding time of the sliding column 704 in the arc groove of the cylindrical cam 702 and improve the adjustment efficiency of the angle of the lower squeegee 707. After the adjustment is completed, the continuous downward movement of the wedge block 610 will gradually lose the extrusion force on the second incomplete rack 711, so that the first incomplete rack 708 will no longer drive the squeegee 707 to move upward through the handover, and the squeegee 707 will be reset. And when the cooperating rod 606 moves upward to reset, the squeegee 707 will also rotate in the reverse direction and lose contact with the film at this time, so as to effectively improve the stability of the film during fitting and improve the quality of the overall fit between the film and the plate; It should be further noted that when the first incomplete rack 708 drives the squeegee 707 to move up and down through the hinge plate, at the same time, under the combined linkage of the transmission plate 611 driving the cutting piece 603 to move, the squeegee 707 will rotate quickly while moving upward, which can improve the conversion speed when scraping bubbles from films with different widths, effectively protect the film while improving the efficiency of bubble discharge.

[0031] Such as Figures 4 to 6As shown, the two-way cylinder 601 is fixedly connected to the top plate 9. A spring is provided between the matching rod 606 and the top plate 9. Both ends of the top plate 9 are fixedly connected with cutting bins, and the cutting bins are fixedly arranged above the matching plate 8. The two-way cylinder 601 drives the cutting slice 603 to adjust its position inside the cutting bin through the adjusting rod 602.

[0032] 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, at this time, by setting a spring at the sliding position between the matching rod 606 and the top plate 9, when the matching rod 606 moves downward, it will continuously compress the spring. At this time, through the rebounding force of the spring and the frictional force between the inclined plate inside the fixed cylinder 605 and the inclined groove inside the matching rod 606, the stability of the matching rod 606 after pressing down can be effectively improved, thereby improving the stability of the pressure adjustment of the second pressing roller 502; It should be noted that when adjusting the position of the cutting slice 603, at this time, the two groups of fixed cylinders 605 will move relatively. And due to the different inclination directions of the internal inclined plates, when the fixed cylinders 605 move relatively, the inclined plates can drive the matching rods 606 to move up and down at the same time, so that the force transmitted from the transmission plate 611 to the connecting rod 10 and the rotating sleeve 11 is in a uniform state, and the force of the second pressing roller 502 pre-rolling the film can be changed in a gentle state, so as to improve the rolling of the position between the film and the plate and fully discharge the bubbles from the middle.

[0033] As Figure 13 shown, the upper end of the moving rod 701 is rotationally clamped to the housing 1. The fixed sleeve 703 is sleeved outside 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.

[0034] During operation, since the surface of the wedge block 610 in contact with the second incomplete rack 711 is set to have a certain arc, when the wedge block 610 moves downward, it will first push the second incomplete rack 711 to slide inside the working bin 710 through the inclined surface, which can quickly drive the moving rod 701 to move upward. Since one end of the sliding column 704 slides inside the arc groove on the surface of the cylindrical cam 702, before the cylindrical cam 702 rotates, the wedge block 610 has already pushed the moving rod 701 to move upward through the inclined surface. When the sliding column 704 slides a certain distance inside the chute of the cylindrical cam 702, the scraper 707 that has been "lifted" at this time will rotate, which can effectively prevent the scraper 707 from rotating first and damaging the film, affecting the quality of the overall fit between the film and the plate; It should be noted that since both the second incomplete rack 711 and the first incomplete rack 708 slide inside the working bin 710, when the wedge block 610 loses the extrusion force on the second incomplete rack 711, the scraper 707 and the moving rod 701 will reversely push the first incomplete rack 708 to slide inside the working bin 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 hinge plate to move, and only after the hinge plate moves will it drive the first incomplete rack 708 to slide reversely. This can prevent the scraper 707 from instantly falling and hitting the surface of the film to cause damage to the film after losing the thrust of the wedge block 610 on the second incomplete rack 711, and can further improve the protection of the film.

[0035] As Figures 6 to 9 shown, both the mating sleeve 607 and the adjusting rod 602 are rotatably connected to the output end of the drive motor 604. The adjusting rod 602 drives the cutting slice 603 to move inside the cutting bin. The cutting slice 603 drives the limiting strip 609 at one end of the arc rod 608 to slide inside the mating plate 8 through the mating sleeve 607. A cutting groove communicating with the inside of the cutting bin is provided at the position of the cutting slice 603 inside the mating plate 8.

[0036] During operation, since the adjusting rod 602 is slidably connected to the mating plate 8 and one end is fixedly connected to an output end of the double-acting cylinder 601, when the double-acting cylinder 601 adjusts the position of the cutting slice 603, at this time, after the inner side of the limiting strip 609 moves inside the mating plate 8, the inner side will closely adhere to the side of the cut dry film. At the same time, since one end of the guiding plate 613 and one end of the limiting strip 609 are both tapered, at this time, it can fully guide the cut film to be discharged through the discharge groove, and can ensure that the cut film can be accurately guided by the limiting strip 609. It should be noted that when the cutting slice 603 moves inside the cutting bin, since the cutting slice 603 is spline-connected to the output end of the drive motor 604, at this time, even if the cutting slice 603 moves, it will not affect the drive motor 604 to drive it to rotate. It can stably cut the edge of the film, and at the same time, after cutting, it can release the bubbles that the scraper 707 "drives" to the edge, which can effectively prevent the bubbles from remaining at the edge position of the film and the plate, affecting the overall bonding quality and improving the quality of subsequent exposure of the PCB board.

[0037] As Figures 4 to 5 shown, both the adjusting rod 602 and the mating sleeve 607 are sleeved on the surface of the output end of the drive motor 604. The drive motor 604 is fixedly connected to the mating plate 8. The adjusting rod 602 is slidably connected to the cutting bin. A stepped groove for placing the copper clad laminate and the dry film is provided inside the mating plate 8.

[0038] During operation, when the film and the plate are placed inside the mating plate 8, since a stepped groove for placing the copper clad laminate and the dry film is provided inside the mating plate 8, first the plate is inserted into the lower stepped groove. After limiting both sides of the plate, then the film is inserted above the mating plate 8, so that the film and the plate are closely attached together. This can ensure the accuracy of their positions during pre-rolling and formal rolling, avoid the situation of the film shifting in position during the rolling process, and effectively improve the effect of the film adhering to the surface of the plate.

[0039] As Figure 9 and Figure 11 shown, the mating rod 606 drives the wedge block 610 to move up and down through the fixing ring 612. The surface of the wedge block 610 is set with a certain arc. The wedge block 610 is made of wear-resistant material. The inclination angle of the inclined plate inside the fixing cylinder 605 is the same as the inclination angle of the inclined groove provided inside the mating rod 606. The connecting plate 12 and the mating plate 8 are fixedly connected.

[0040] During operation, through the contact between the wedge block 610 and the second incomplete rack 711, the second incomplete rack 711 can be pushed to slide inside the working chamber 710, which can effectively adjust the up and down movement of the scraping plate 707, improve the effect of protecting the film, and avoid damaging the surface of the film. And because the inclination angle of the inclined plate inside the fixing cylinder 605 is the same as the inclination angle of the inclined groove provided inside the mating rod 606, when the fixing cylinder 605 drives the mating rod 606 to move up and down and needs to be stabilized, at this time, through the cooperation of the inclined surfaces, the situation of the mating rod 606 falling off after being "lifted" can be avoided, which can effectively improve the stability after applying pressure to the second pressing roller 502, thus facilitating the extrusion of the middle part of the film and the plate, and improving the exposure quality of the PCB board in the integrated circuit.
