Description

Technical Field

[0001] The present application relates to the field of laminating equipment, and in particular, to a solar screen mold body pressing equipment and a pressing process. Background Art

[0002] A solar cell is a device that converts light energy into electrical energy through the photovoltaic effect or chemical effect, and plays a core role in the photovoltaic system. Based on its advantages such as cleanliness, safety, and renewable energy, it plays an important role in promoting the development of future energy and has broad development prospects.

[0003] Currently, during the formation of solar cells, printing is an important link; related technologies generally use screen printing technology to achieve circuit printing, and a screen is usually required in this process; the screen usually consists of a screen frame, a polyester screen cloth, a hot melt rubber ring, and a screen yarn. Among them, the polyester screen cloth is fixedly installed in the screen frame, and the hot melt rubber ring connects the metal wire mesh and the polyester screen cloth; the metal wire mesh is formed with specific mesh holes by laser cutting. By pouring tin liquid on the screen frame and using a squeegee to scrape the tin liquid, the tin liquid flows from the mesh holes of the specific pattern on the screen onto the solar panel to achieve printing.

[0004] At this time, in order to prevent the tin liquid from flowing down from the non-pattern area of the metal screen yarn, the metal screen yarn needs to be treated; one method is to apply a photosensitive glue (latex), and the photosensitive glue can block the gaps of the metal screen after curing; another method is to glue a polyimide film on the metal screen to block the tin liquid and improve the printing accuracy.

[0005] Regarding the above related technologies, there is a lack of a technical solution that can efficiently attach the polyimide film to the screen, making it difficult to meet the current production capacity requirements, and there is still much room for improvement in the process of laminating the screen yarn. Summary of the Invention

[0006] In order to improve the attachment efficiency during the screen laminating process, the present application provides a solar screen mold body pressing equipment and a pressing process.

[0007] In a first aspect, a solar screen mold body pressing equipment provided by the present application adopts the following technical solution:

[0008] A solar screen mold body pressing equipment includes a frame, and further includes a carrier disposed at the frame and having a recess for placing the screen inside; a lower heating component disposed on the frame and extending to the bottom of the recess for heating the screen; an upper heating component and a lifting drive component. The lifting drive component is disposed on the frame, the upper heating component is connected to the lifting drive component and is located above the lower heating component, and the lifting drive component is used to drive the upper heating component to press down the polyimide film and the screen.

[0009] By adopting the above technical solution, a two-sided heating method is used to quickly thermocompression-fuse the polyimide film and the screen printing stencil. The polyimide film is evenly heated, has good adhesion compactness, and the operation can be carried out continuously without interruption. Cooperating with the lifting drive assembly, the lamination operation is fast and efficient, and both the adhesion efficiency and quality during the screen printing stencil laminating process are improved.

[0010] Preferably, a cooling assembly is further included. The cooling assembly includes a cooling base plate and a circulation component. The cooling base plate is fixedly arranged on the carrier and is located at the bottom of the recessed part. A cooling water channel is formed inside the cooling base plate, and a relief channel for thermocompression of the screen printing stencil is provided in the middle of the cooling base plate. The circulation component is respectively communicated with both ends of the cooling water channel and is used for circulating and introducing cooling water into the cooling water channel to cool the polyester screen cloth by the cooling base plate.

[0011] By adopting the above technical solution, the cooling assembly can reduce the influence of temperature rise on the polyester screen cloth caused by heating, and the overall structural stability of the screen printing stencil is guaranteed.

[0012] Preferably, the cooling base plate includes an upper frame body and a lower frame body that are fixedly connected to each other. The upper frame body is fixedly connected to the carrier. A first splicing groove is provided on the upper frame body, and a second splicing groove is provided at the lower frame body. The first splicing groove and the second splicing groove are combined to form the cooling water channel.

[0013] By adopting the above technical solution, the cooling base plate is divided into an upper frame body and a lower frame body, which is convenient for milling and forming the cooling water channel. At the same time, it is beneficial to form more complex water channel structures, such as serpentine structures, inside the cooling base plate, which is beneficial to extending the cooling path to improve the cooling effect.

[0014] Preferably, the circulation component includes a return water pipe, a water outlet pipe, a water outlet pump, a water storage tank, an air-cooled box, and an air-cooling element. Both ends of the return water pipe are respectively communicated with the water storage tank and one end of the cooling water channel. The return water pipe is in a serpentine structure and passes through the air-cooled box. The air-cooling element is arranged inside the air-cooled box, and the air-cooling element blows cooling air towards the serpentine part of the return water pipe. Both ends of the water outlet pipe are respectively communicated with the cooling water channel and the water outlet pump, and the water outlet pump is communicated with the water storage tank.

[0015] By adopting the above technical solution, the cooling water cools the cooling base plate through the cooling water channel. During this process, the temperature of the cooling water after heat absorption rises, and then it flows through the air-cooled box. At this time, the air-cooling element cools the serpentine part of the return water pipe, and the serpentine return water pipe plays a role in extending the flow distance, and the cooling effect is good. The cooled cooling water flows into the water storage tank, and then under the action of the water outlet pump, the cooling water flows back into the cooling water channel through the water outlet pipe again to realize the circulation of the cooling water.

[0016] Preferably, the vehicle is slidably arranged on the rack through a sliding component. The sliding component includes a slider fixedly arranged on the vehicle and a slide rail fixedly arranged on the rack. The slider is slidably matched with the slide rail, and one end of the slide rail extends to the outside of the rack.

[0017] By adopting the above technical solution, with the mutual cooperation of the slide rail and the slider, the vehicle can be drawn out to the outside of the rack, so as to facilitate the replacement and transfer of the screen plate located on the vehicle, and the structure is practical.

[0018] Preferably, it further includes a floating clamping component and a linkage component. The floating clamping component is arranged on the vehicle in a liftable manner. The linkage component is arranged on the rack. The floating clamping component is slidably matched with the linkage component. When the vehicle slides to the outside of the rack, the linkage component drives the floating clamping component to extend above the vehicle to open relative to the screen plate. When the vehicle slides to the inside of the rack, the linkage component drives the floating clamping component to descend, while supporting the screen plate and clamping the periphery of the screen plate.

[0019] By adopting the above technical solution, under the drive of the linkage component, the floating clamping component can clamp the periphery of the screen plate, improving the stability during the screen plate film covering and forming process. At the same time, when the vehicle is moved to the outside of the rack, the screen plate can be opened under the drive of the linkage component, which is beneficial to the replacement and transfer of the screen plate.

[0020] Preferably, the floating clamping component includes a mounting frame, a pulley and a plurality of claw parts. The pulley is fixedly installed at the bottom of the mounting frame, and the plurality of claw parts are fixedly installed at the top of the mounting frame. A sliding hole for the plurality of claw parts to slide is vertically penetrated through the vehicle. The pulley is slidably matched with the linkage component. The linkage component is used to drive the pulley to move up and down, and the claw parts are used to actively clamp the edge of the screen frame.

[0021] By adopting the above technical solution, the pulley can enable the floating clamping component to be slidably matched with the linkage component. The mounting frame plays a role in connecting the claw parts and the pulley. During the movement of the vehicle, the claw parts can be pushed to move. Under the guidance of the pulley, the floating clamping component can move correspondingly with the movement of the vehicle. Correspondingly, while the linkage component drives the pulley to move up and down, the lifting and clamping movement of the claw parts is realized, and the structural cooperation is good.

[0022] Preferably, the linkage assembly includes a first linkage rail and a second linkage rail respectively and fixedly installed on the frame. The first linkage rail and the second linkage rail are both provided with positioning grooves along the length direction. The positioning grooves are in sliding fit with the floating clamping assembly. The height of the second linkage rail is greater than that of the first linkage rail. One end of the first linkage rail is connected to the second linkage rail and has an arc transition.

[0023] By adopting the above technical solution, during the process of the floating clamping assembly sliding on the first linkage rail and the second linkage rail with a height difference, the floating clamping assembly can perform a lifting movement during the translation process, and the structure is ingenious and practical.

[0024] Preferably, the jaw part includes a fixed connecting piece and a hook member. The fixed connecting piece is fixedly connected to the mounting frame body. The hook member is rotatably arranged at the fixed connecting piece. One side of the hook member has a guiding rod. The carrier has an arc-shaped chute. The guiding rod is in sliding fit with the arc-shaped chute. When the floating clamping assembly extends above the carrier, the arc-shaped chute guides the hook member to open towards the outside of the screen plate. When the floating clamping assembly descends, the arc-shaped chute guides the hook member to buckle towards the edge of the screen plate.

[0025] By adopting the above technical solution, during the lifting movement of the jaw part, the hook member is guided by the guiding rod and the arc-shaped chute, thereby realizing the movable clamping action. When buckling the edge of the screen plate, the stability of the screen plate during placement is further improved. At the same time, when the floating clamping assembly rises, the hook member opens outwards compared to the screen plate, which is beneficial for taking and placing the screen plate, and the structure is ingenious.

[0026] In the second aspect, a lamination process for a solar screen plate mold body provided by the present application adopts the following technical solution:

[0027] A lamination process adopted by a solar screen plate mold body lamination device includes the following steps:

[0028] S1: Start the device and set the heating temperature;

[0029] S2: Extend the carrier out of the frame, and then place the screen plate on the carrier;

[0030] S3: Send the carrier into the frame. At this time, the lower heating component heats the screen plate, and at the same time, start the cooling component to cool the polyester mesh cloth part of the screen plate;

[0031] S4: Drive the carrier to extend out of the frame again, and then place the polyimide film on the screen plate;

[0032] S5: Send the carrier into the frame again, and start the lifting drive component to press the polyimide film down by the upper heating component;

[0033] S6: Finally, extend the vehicle out of the rack and take out the finished product after hot pressing;

[0034] S7: Repeat steps S1 - S6.

[0035] By adopting the above technical solution, the screen printing plate and the polyimide film can realize off - machine operation, which is simple, safe and fast.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

Detailed implementation manners

[0048] The following further describes the present application in detail with reference to the Figure 1-7 accompanying drawings.

[0049] Embodiment 1:

[0050] The embodiment of the present application discloses a solar screen mold pressing device.

[0051] Referring to Figure 1 , the device includes a frame 1, a vehicle 2, an upper heating assembly 3, a lower heating assembly 4, and a lifting drive assembly 5. Among them, the vehicle 2, the upper heating assembly 3, the lower heating assembly 4, and the lifting drive assembly 5 are respectively arranged at the frame 1. The frame 1 plays a role in supporting each component. The specific structure of the frame 1 can be adjusted correspondingly according to actual needs and is not limited herein.

[0052] In addition, the vehicle 2 mainly serves to place the screen. Among them, in this embodiment, the vehicle 2 is arranged in a rectangular plate shape and is arranged horizontally. In other embodiments, it can also be arranged as a frame structure or a seat structure, and any structure that can realize placing the screen can be tried. The vehicle 2 can usually be directly fixedly installed on the frame 1. For example, a cushion block can be fixedly installed on the frame 1, and the vehicle 2 can be fixedly installed at the cushion block. To facilitate the subsequent film covering operation, a recess 21 for placing the screen is provided in the middle of the vehicle 2. The recess 21 is in the shape of a concave hole in this embodiment and can also be in the shape of a concave pit in other embodiments, which is not specifically limited herein. At this time, the screen can be placed on the top of the vehicle 2, so that the metal mesh and part of the polyester mesh of the screen overlap at the recess 21, facilitating the subsequent film covering operation.

[0053] Based on this, in this embodiment, a two-sided heating method is adopted to thermally press and adhere the polyimide film to the metal mesh of the screen plate, so as to improve the overall heating efficiency and the uniformity of heat reception. Specifically, the lower heating assembly 4 is fixedly installed on the frame 1 and is located directly below the carrier 2. The lower heating assembly 4 mainly includes a lower heating plate and lower heating rods. The lower heating rods are buried in the lower heating plate, and the lower heating rods can heat the lower heating plate to raise the temperature of the lower heating plate. The lower heating plate extends upward to the bottom of the recess 21. When the screen plate is placed on the carrier 2, the lower heating plate can contact the metal mesh, thereby heating the screen plate.

[0054] It should be noted that the lower heating assembly 4 can also be set in a liftable form structure. For example, the lower heating assembly 4 can also include a lower heating driving member. The lower heating driving member can be selected from structures such as cylinders, linear modules, or gear racks that can output lifting motion. The lower heating driving member is fixedly installed on the frame 1, and the lower heating plate is fixedly installed on the output shaft of the lower heating driving member, so that the lower heating plate can contact the screen plate in a lifting manner, and the flexibility of the structure is improved.

[0055] Continue to refer to Figure 1 , at the same time, the lifting driving assembly 5 is fixedly installed on the frame 1. Specifically, the lifting driving assembly 5 is fixedly installed on the frame 1. The lifting driving assembly 5 can be selected as a cylinder element. In other embodiments, it can also be selected as an oil cylinder, an electric telescopic rod or other elements that can output reciprocating linear motion. The telescopic rod of the lifting driving assembly 5 is arranged vertically downward; at the same time, the upper heating assembly 3 includes an upper heating plate and upper heating rods. The upper heating plate is arranged horizontally. The upper heating plate is fixedly installed at the telescopic rod of the lifting driving assembly 5. At the same time, the upper heating plate is buried inside the upper heating plate. The upper heating rods can heat the upper heating plate; at this time, the upper heating plate is located directly above the carrier 2 and the lower heating assembly 4. Starting the lifting driving assembly 5 can drive the upper heating plate to move downward. The upper heating plate presses the screen plate and the polyimide film located above the screen plate. Finally, under the synchronous heating of the upper and lower sides, the attachment of the polyimide film on the screen plate is realized.

[0056] The implementation principle of Embodiment 1 of this application is: by heating the screen plate and the polyimide film from the upper and lower sides, efficient heat conduction heating is realized, the heating efficiency is improved, and at the same time, the uniformity of heat reception of the screen plate and the polyimide is improved, and the attachment efficiency is further improved.

[0057] Embodiment 2:

[0058] The difference between this embodiment and Embodiment 1 is that, referring to Figure 2 , this embodiment further includes a cooling assembly 6. The cooling assembly 6 is used to cool the polyester mesh cloth to reduce the influence on the polyester mesh cloth during the heating process of the metal mesh.

[0059] Specifically, referring to Figure 3 and Figure 4 , the cooling assembly 6 includes a cooling base plate 61 and a circulation component 62. Among them, the cooling base plate 61 is fixedly arranged on the vehicle 2 and is located at the bottom of the recess 21. The cooling base plate 61 includes an upper frame body 611 and a lower frame body 612. In this embodiment, both the upper frame body 611 and the lower frame body 612 are in a rectangular shape, and both are hollow inside. The upper frame body 611 and the lower frame body 612 are similar in structure. The two are overlapped with each other and can be fixedly connected by welding. At this time, after the upper frame body 611 and the lower frame body 612 are fixed to each other, an avoidance channel for hot pressing the screen plate is formed in the middle of the cooling base plate 61 for the lower heating assembly 4 to pass through.

[0060] The upper frame body 611 is sleeved in the recess 21, and the upper frame body 611 and the vehicle 2 are fixedly connected by welding. At the same time, there is a cooling water channel inside the cooling base plate 61. Cooling water is introduced into the cooling water channel to cool the cooling base plate 61, and then the polyester mesh is cooled. Specifically, to improve the cooling effect of the cooling base plate 61, the cooling water channel inside the cooling base plate 61 can be in a serpentine structure surrounding the four sides of the cooling base plate 61. Among them, a first splicing groove is recessed from the outer surface to the inner surface on the side surface of the upper frame body 611 facing the lower frame body 612; in addition, a second splicing groove is recessed from the outer surface to the inner surface on the side surface of the lower frame body 612 facing the upper frame body 611. Both the first splicing groove and the second splicing groove are in a serpentine structure. After the upper frame body 611 and the lower frame body 612 are fixed, the first splicing groove and the second splicing groove are combined to form a cooling water channel, and both ends of the cooling water channel are opened on the same side of the cooling base plate 61.

[0061] Furthermore, the circulation component 62 is respectively communicated with both ends of the cooling water channel. The circulation component 62 is used to introduce cooling water at one end of the cooling water channel, and at the same time is used to receive the heated cooling liquid at the other end of the cooling water channel, and cool the cooling liquid and then send it back into the cooling water channel again to achieve the function of circulating cooling.

[0062] Specifically, continue to refer to Figure 4 , the circulation component 62 includes a return water pipe 621, a water outlet pipe 622, a water outlet pump 623, a water storage tank 624, an air-cooled box 625 and an air-cooled element 626.

[0063] One end of the return water pipe 621 is fixedly connected to the cooling seat plate 61, and one end of the return water pipe 621 is communicated with the cooling water channel. At this time, the heated cooling water in the cooling water channel can flow into the return water pipe 621 from the cooling water channel. At the same time, the other end of the return water pipe 621 is fixedly connected to the water storage tank 624. At this time, a return water hole is penetrated through the water storage tank 624, and the return water pipe 621 is communicated with the inside of the water storage tank 624 through the return water hole, and the cooling water can be stored through the return water pipe 621 to the water storage tank 624.

[0064] Based on this, in order to cool the returned cooling water, the return water pipe 621 can be made of a metal material, such as copper, aluminum or iron, which is not specifically limited here. At the same time, the return water pipe 621 passes through the inside of the air-cooled box 625. Among them, an inlet and an outlet are respectively penetrated through the opposite two side walls of the air-cooled box 625. The return water pipe 621 enters the inside of the air-cooled box 625 through the inlet and passes out from the outlet of the air-cooled box 625. The return water pipe 621 located inside the air-cooled box 625 is arranged in a serpentine structure to extend the flow path length of the cooling water inside the air-cooled box 625.

[0065] At the same time, the air-cooling element 626 can be selected as a fan. The air-cooling element 626 is fixedly installed in the air-cooled box 625. The fan has an air outlet end and an air inlet end. The air outlet end of the air-cooling element 626 faces the serpentine part of the return water pipe 621. When the air-cooling element 626 is started, the air-cooling element 626 can blow cooling air towards the serpentine part of the return water pipe 621, thereby cooling the cooling water located inside the return water pipe 621.

[0066] At the same time, the water outlet pump 623 is fixedly installed on the water storage tank 624. The water outlet pump 623 has a water inlet and a water outlet. The water inlet of the water outlet pump 623 is communicated with the bottom of the water storage tank 624. The two ends of the water outlet pipe 622 are respectively fixedly connected to the water outlet pump 623 and the cooling seat plate 61; at the same time, the two ends of the water outlet pipe 622 are respectively communicated with the cooling water channel and the water outlet of the water outlet pump 623; at this time, the water outlet pump 623 flows the cooling water in the water storage tank 624 to the cooling water channel through the water outlet pipe 622, so as to realize the cooling temperature control of the cooling seat plate 61.

[0067] Refer to Figure 5, during the actual operation of the stencil, replacing the stencil and the polyimide film inside the equipment will pose a safety hazard. Based on this, the difference between this embodiment and Embodiment 1 is also that the carrier 2 is slidably arranged at the frame 1 through the sliding assembly 9. Specifically, the sliding assembly 9 includes a slider 91 and a slide rail 92. The slider 91 is fixedly installed at the bottom of the carrier 2. In addition, the slide rail 92 is fixedly installed at the frame 1, and one end of the slide rail 92 extends outside the frame 1. The slider 91 is slidably engaged with the slide rail 92. At this time, with the mutual cooperation of the slide rail 92 and the slider 91, the carrier 2 can be drawn out to the outside of the frame 1 to facilitate the replacement and transfer of the stencil located on the carrier 2. Correspondingly, to improve the stability of the carrier 2 during movement, the mutually cooperating slide rail 92 and slider 91 can be set in two groups, and the two groups of slide rail 92 and slider 91 can be respectively arranged on both sides of the carrier 2 to improve the stability of the carrier 2 during displacement.

[0068] Furthermore, during the process of heat-sealing the polyimide film to the stencil, the stability and position accuracy of the stencil when placed are important factors affecting the subsequent printing accuracy of the stencil. For example, during the up-and-down pressing or the horizontal movement of the carrier 2, on the one hand, because the stencil needs to be subjected to pressure, it may cause the stencil to deform and the stencil to shift. On the other hand, the stencil may slip and shift during the horizontal movement. If the stencil shifts, it will cause the thermal pressing position to be misaligned, the polyimide film to shift, and ultimately cause the blocking area to shift.

[0069] Therefore, to improve the stability of the stencil during thermal pressing, the equipment further includes a floating clamping assembly 7 and a linkage assembly 8. The floating clamping assembly 7 is used to clamp the periphery of the stencil, and the linkage assembly 8 is used to drive the floating clamping assembly 7 to lift, driving the floating clamping assembly 7 to perform clamping and releasing actions.

[0070] Specifically, the linkage assembly 8 includes a first linkage rail 81 and a second linkage rail 82. The first linkage rail 81 and the second linkage rail 82 are respectively arranged along the horizontal direction. The first linkage rail 81 and the second linkage rail 82 are respectively fixedly installed on the frame 1. The height of the second linkage rail 82 is greater than the height of the first linkage rail 81, and one end of the first linkage rail 81 and the second linkage rail 82 are connected to each other, and the connection part is in an arc transition. The placement directions of the first linkage rail 81 and the second linkage rail 82 are parallel to the guide rail. The floating clamping assembly 7 is slidably engaged with the linkage assembly 8, and the linkage assembly 8 is used to drive the floating clamping assembly 7 to perform lifting movement.

[0071] Among them, referring to Figure 5 and Figure 6, the floating clamping assembly 7 includes a mounting frame 71, pulleys 72 and a plurality of jaw parts 73; the mounting frame 71 is in a C-shaped structure in this embodiment, the mounting frame 71 is arranged horizontally, the pulleys 72 are fixedly installed at the bottom of the mounting frame 71, and the pulleys 72 are slidably matched with the linkage assembly 8. Specifically, positioning grooves 83 are formed along the length direction at the tops of the first linkage rail 81 and the second linkage rail 82, the positioning grooves 83 of the first linkage rail 81 and the second linkage rail 82 communicate with each other, the pulleys 72 are slidably arranged in the positioning grooves 83, and the positioning grooves 83 can position the opposite sides of the pulleys 72. Under the action of the linkage assembly 8, if the mounting frame 71 moves horizontally, the pulleys 72 will drive the mounting frame 71 to move up and down. Here, it should be noted that two sets of the mutually cooperating linkage assembly 8 and pulleys 72 can be provided, and the two sets of linkage assemblies 8 can be respectively located below the opposite sides of the carrier 2. By providing multiple sets of linkage assemblies 8 and pulleys 72, the stability of the mounting frame 71 during movement can be improved.

[0072] Meanwhile, referring to Figure 6 and Figure 7 , a plurality of jaw parts 73 are fixedly installed at the top of the mounting frame 71, and the jaw parts 73 are used for clamping the periphery of the screen plate to improve the placement stability of the screen plate. Specifically, a plurality of jaw parts 73 can be provided, such as four, six or seven, etc. In this embodiment, four groups are selected as an example. The plurality of jaw parts 73 can be respectively arranged around the mounting frame 71. In other embodiments, they can also be arranged on the opposite sides of the mounting frame 71 for clamping the screen plate around to improve the stability during clamping. The specific number and arrangement of the jaw parts 73 can be adjusted according to actual needs. In this embodiment, the four groups of jaw parts 73 are evenly distributed on the opposite sides of the mounting frame 71 and are arranged in a rectangular shape.

[0073] In addition, the jaw parts 73 can be arranged to be movable up and down at the carrier 2. A plurality of sliding holes 22 for the jaw parts 73 to slide through are vertically penetrated through the carrier 2. The number and distribution of the sliding holes 22 are consistent with those of the jaw parts 73. The jaw parts 73 pass through the sliding holes 22, and the surface of the jaw parts 73 is in sliding contact with the hole walls of the sliding holes 22. At this time, during the horizontal movement of the carrier 2, the jaw parts 73 can form force points, and under the drive of the carrier 2, the mounting frame 71 is driven to move horizontally, and the pulleys 72 are driven to slide horizontally in the linkage assembly 8, and the floating clamping assembly 7 realizes horizontal movement. During the horizontal movement of the floating clamping assembly 7, it reacts on the jaw parts 73. When the linkage assembly 8 slides to the first linkage rail 81 and the second linkage rail 82, the jaw parts 73 are driven to move up and down.

[0074] Continuing to refer to Figure 6 and Figure 7, to achieve the edge clamping and positioning of the screen plate, the jaw part 73 is used to actively clamp the edge of the screen plate. The jaw part 73 includes a fixed connecting piece 731 and a hook piece 732. The fixed connecting piece 731 is arranged in a long rod shape. The fixed connecting piece 731 is along the vertical direction. The bottom end of the fixed connecting piece 731 is fixedly installed on the installation frame 71. The other end of the fixed connecting piece 731 extends to the sliding hole 22, and the surface of the fixed connecting piece 731 is in sliding contact with the sliding hole 22, so as to realize the lifting guidance of the jaw part 73.

[0075] At the same time, the hook piece 732 is in a reverse hook shape in this embodiment. The hook piece 732 is located at the end of the fixed connecting piece 731 away from the installation frame 71. One end of the hook piece 732 is rotationally installed on the fixed connecting piece 731 by means of hinge. At the same time, a guide rod 733 is fixedly installed on one side of the hook piece 732. The guide rod 733 is arranged along the horizontal direction.

[0076] At the same time, the carrier 2 is provided with an arc-shaped sliding groove 734. The arc-shaped sliding groove 734 is recessed from the outside to the inside at the hole wall of the sliding hole 22. The head of the arc-shaped sliding groove 734 extends linearly from bottom to top, and then bends arcuately toward the side opposite to the screen plate at the tail end; the guide rod 733 extends into the arc-shaped sliding groove 734, and the surface of the guide groove is in sliding contact with the groove wall of the arc-shaped sliding groove 734. At this time, the guide rod 733 is slidably fitted in the arc-shaped sliding groove 734.

[0077] At this time, when the floating clamping assembly 7 moves upward, the guide rod 733 will slide upward in the arc-shaped sliding groove 734 and enter the tail of the arc-shaped sliding groove 734 from the head. At this time, under the guidance of the arc-shaped sliding groove 734, the hook piece 732 will open relative to the screen plate to realize the loosening of the screen plate. If the floating clamping assembly 7 moves downward, the guide rod 733 will move to the straight line segment at the bottom of the arc-shaped sliding groove 734; at this time, under the guidance of the arc-shaped sliding groove 734, the hook piece 732 will buckle toward the edge of the screen plate, and at this time, it will abut against the side and top of the screen plate, and the screen plate is positioned.

[0078] Furthermore, when the linkage assembly 8 is set, the second linkage rail 82 is closer to the outside of the frame 1 than the first linkage rail 81. At this time, if the carrier 2 moves to the outside of the frame 1, the floating clamping assembly 7 cooperates with the second linkage rail 82; at this time, the floating clamping assembly 7 can extend above the carrier 2, and the arc-shaped sliding groove 734 guides the hook piece 732 to open toward the outside of the screen plate, and the screen plate is loosened, and then the screen plate can be taken and placed. In addition, if the carrier 2 moves to the inside of the frame 1, the floating clamping assembly 7 cooperates with the first linkage rail 81, and the floating clamping assembly 7 descends, and the arc-shaped sliding groove 734 guides the hook piece 732 to buckle toward the edge of the screen plate to realize the positioning of the screen plate.

[0079] The implementation principle of Embodiment 2 is as follows: On the one hand, by circulating cooling water, the cooling component 6 can reduce the influence of heating on the temperature rise of the polyester mesh cloth, ensuring the overall structural stability of the screen plate. On the other hand, when the carrier 2 is driven to slide outside the frame 1, the linkage component 8 drives the floating clamping component 7 to extend above the carrier 2 to open relative to the screen plate, facilitating the picking and placing of the screen plate. At the same time, when the carrier 2 slides inside the frame 1, the linkage component 8 drives the floating clamping component 7 to descend, supporting the screen plate while clamping the four sides of the screen plate to improve the position stability of the screen plate and the polyimide film during the hot pressing process.

[0080] The embodiment of the present application also discloses a solar screen plate die pressing process, including the following steps:

[0081] S1: Start the equipment and set the heating temperature. At this time, the upper heating plate and the lower heating plate can be heated to 190 °C - 210 °C respectively. For example, it can be set to 190 °C, 200 °C, and 210 °C. In this embodiment, the heating temperature is set to 200 °C as an example.

[0082] S2: Extend the carrier 2 outside the frame 1. At this time, it is necessary to check whether all the hook members 732 in the jaw portion 73 are fully opened. If not, it indicates that the outward movement position of the carrier 2 is insufficient. If all the hook members 732 are fully opened, then place the screen plate on the carrier 2. It should be noted that when placing the screen plate, it needs to overlap with the recessed portion 21.

[0083] S3: Push the carrier 2 into the frame 1. At this time, the lower heating component 4 heats the screen plate to 200 °C, and at the same time, start the cooling component 6 to cool the polyester mesh cloth part of the screen plate. The temperature of the cooling component 6 should be as low as possible below 100 °C to ensure the protection effect on the polyester mesh cloth.

[0084] S4: Drag the carrier 2 again to extend the carrier 2 outside the frame 1, and then place the polyimide film on the screen plate. It should be noted that the polyimide film should cover the metal mesh of the screen plate.

[0085] S5: Drag the carrier 2 again and send the carrier 2 into the frame 1. Start the lifting drive component 5 to press the polyimide film down by the upper heating component 3. It can be kept under pressure for a period of time, such as maintaining the pressing state for 10 - 30 s, which can be 10 s, 20 s, or 30 s. In this embodiment, it is kept under pressure for 20 s as an example, until the polyimide film is heat-sealed to the metal mesh.

[0086] S6: Finally, drag the carrier 2 out of the frame 1, open all the hook members 732, and take out the finished product.

[0087] S7: Repeat steps S1 - S6 to achieve the cyclic processing process.

[0088] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
