Description

Technical Field

[0001] This invention relates to the field of conveying and peeling equipment technology, and in particular to a screen sheet peeling equipment. Background Technology

[0002] The sheet material for the electroformed main / fine grid is formed by electroforming. After electroforming / decoction, the sheet needs to be peeled off from the substrate and then stretched to form a grid. The size of the sheet is generally 300mm×300mm and the thickness is between 5um and 30um. No creases are allowed to be made on the sheet during the peeling process. Once creases are made, the sheet must be scrapped.

[0003] Currently, the main methods for peeling are direct manual peeling or manual peeling with the aid of simple jigs. For sheets with a thickness of more than ten micrometers and many connection points, manual peeling keeps the defect rate within a controllable range. However, as the requirements for reducing the silver paste consumption per screen in solar cell printing become increasingly stringent, the thickness of the main and fine grid screen sheets is continuously decreasing. With the reduction in sheet thickness, the peeling defect rate increases exponentially. When the sheet thickness is within a few micrometers, the defect rate for manual peeling can reach over 50%. In addition, the peeling process requires a high level of skill. Controlling the consistency of peeling techniques and stabilizing the peeling yield is a major challenge in this process. Lack of skill in peeling techniques can easily lead to batch scrap, thus limiting its application.

[0004] Therefore, it is necessary to provide a screen printing sheet peeling device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a screen printing sheet peeling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a screen sheet peeling device is designed that can achieve rapid peeling of the sheet while ensuring the peeling effect.

[0007] Based on the above ideas, the present invention provides the following technical solution: a screen printing sheet peeling device, comprising a frame and a conveyor belt system mounted on the frame, the conveyor belt system including a transmission belt for conveying workpieces, and adhesive tape being adhered to the workpieces; a peeling component corresponding to the adhesive tape is provided on the front side of the frame; a control component for driving the peeling component is provided on the frame; and a support plate corresponding to the position of the transmission belt and movably fitted with the control component is provided inside the frame; after the control component is activated to move the peeling component above the adhesive tape, the peeling component can be driven to descend and adhere to the adhesive tape, at which time the control component can drive the support plate to rise to support the transmission belt.

[0008] As a further aspect of the present invention: the control component includes a base fixedly mounted on the frame, the base being divided into front and rear sections, a motor being fixedly mounted on the front base, a round shaft being mounted between the output shaft of the motor and the rear base, a guide groove being provided on the round shaft for sliding engagement with the peeling component, and a cam being fixedly mounted on the outer surface of the round shaft for movably engaging with the support plate.

[0009] As a further aspect of the present invention: the guide groove includes a first guide groove and a second guide groove that are connected on both sides, wherein the depth dimension of the first guide groove based on the circular shaft is smaller than the depth dimension of the second guide groove based on the circular shaft.

[0010] As a further aspect of the present invention: the cam has a convex surface and a flat surface, the two sides of the flat surface corresponding to the two sides of the first guide groove, and the two sides of the convex surface corresponding to the two sides of the second guide groove.

[0011] As a further aspect of the present invention: the second guide groove includes a first inclined groove and a second inclined groove that are connected to each other, the opposite sides of the first inclined groove and the second inclined groove are respectively connected to the two sides of the first guide groove, and the depth dimension of the second inclined groove based on the circular shaft is equal to the depth dimension of the first guide groove based on the circular shaft.

[0012] As a further aspect of the present invention: the peeling assembly includes a cantilever slidably mounted on a front base. The cantilever is U-shaped and has two ends. The first end is slidably fitted onto the front base, and the second end is fixedly mounted with a rotatable roller. The roller can rotate freely based on the second end of the cantilever itself. An insert is rotatably mounted on the first end of the cantilever and slidably mounted in a first guide groove.

[0013] As a further aspect of the present invention: a vertical groove is provided on the aforementioned base, and two locking blocks are provided in the vertical groove. The first locking block slides vertically and vertically with the vertical groove, and the second locking block slides forward and backward with the first locking block. The second locking block is fixedly connected to the cantilever, and the cantilever can move forward and backward and up and down relative to the base based on the vertical groove and the two locking blocks.

[0014] As a further aspect of the present invention: a gap is provided between the roller and the top of the transmission belt, and the insert is located in the first guide groove at this time; when the insert enters the second guide groove, the roller can be driven to descend by the cantilever.

[0015] As a further embodiment of the present invention: the support plate includes a slide plate that slides with the rear base, a side plate that is fixedly installed on the surface of the slide plate and moves in contact with the cam, and a circular plate that is fixedly installed on the surface of the side plate away from the slide plate. The side plate and the circular plate are both vertically corresponding to the transmission belt; the workpiece is located in the area above the circular plate, and the tape is located in the area above the side plate and the circular plate.

[0016] As a further embodiment of the present invention: a top plate is fixedly installed on the side plate and an opening adapted to the size of the top plate is provided on the transmission belt. An arc-shaped surface is provided on the top of the top plate. When the top plate rises with the side plate, the lowest point of the arc-shaped surface coincides with the top surface of the transmission belt and the lowest point of the roller after it descends. The center of the virtual circle corresponding to the arc-shaped surface is concentric with the center of the roller after it descends.

[0017] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the transmission belt, the control component and the peeling component, the peeling component can be driven to move back and forth and up and down. When moving backward and approaching the tape, the peeling component is in an upward state. The vertical offset from the transmission belt can effectively reduce frictional damage to the workpiece and avoid contact with the workpiece causing positional displacement, thereby ensuring the correct contact between the peeling component and the tape.

[0018] Next, as it moves backward into position, the peeling assembly automatically descends and adheres to the tape. At this point, the peeling assembly and the workpiece are staggered, which avoids wrinkles in the tape after adhesion due to the height difference between the sheet, the peeling assembly, and the substrate. It also avoids squeezing damage to the sheet and substrate when the peeling assembly descends, ensuring the overall quality stability of the workpiece and ensuring smooth peeling of the sheet when the peeling assembly is reset.

[0019] Then, as it moves forward, the sheet can be quickly peeled off from the substrate using tape, while the substrate remains on the conveyor belt. When the peeling component is guided to move by the control component to complete the peeling, the peeling process of the peeling component is smoother. The overall peeling efficiency is higher, and it is easier to reprocess the substrate and sheet. Integrating the structure into the frame facilitates layout and maintenance, making it more practical.

[0020] Meanwhile, through the cooperation of the transmission belt, control components, and support plate, the support plate does not rise when the peeling component moves backward, so it will not affect the movement of the transmission belt or cause it to be worn. When the peeling component moves backward and forward, the support plate can rise to support the transmission belt. At this time, the peeling component can form an effective bond with the tape, avoiding bending and deformation of the transmission belt that would affect the bonding effect. Furthermore, when the peeling component moves forward to peel off the sheet, the support of the transmission belt keeps the substrate level, thus effectively reducing tearing damage when the sheet is separated from the substrate and ensuring the peeling quality of the sheet.

[0033] Example 1:

[0034] Please see Figures 1 to 7 This invention provides a substrate sheet peeling device, mainly used to achieve rapid peeling of sheets based on substrates while ensuring effective peeling. The device includes a frame 1, on which a conveyor belt system for transporting workpieces 7 is mounted. The conveyor belt system has a drive belt 2, on which the workpieces 7 are placed and moved. In this embodiment, the frame 1 and drive belt 2 are shown as a partial configuration, with the workpieces 7 in a substrate and sheet bonded together. Adhesive tape 8 is pre-attached to one corner of the substrate and sheet, with the adhesive side of the tape 8 positioned between the substrate and sheet. In the above structure, the conveyor belt system, drive belt 2, and adhesive tape 8 are all existing mature technologies and will not be described in detail here. The pre-attachment of the tape 8 can be achieved manually or through existing mechanisms.

[0035] Among them, such as Figure 1 As shown, a peeling assembly 4 corresponding to the tape 8 is provided on the front side of the frame 1. When the workpiece 7 is conveyed by the transmission belt 2, the tape 8 and the peeling assembly 4 are directly opposite each other. A control assembly 3 for driving the peeling assembly 4 is provided on the frame 1. In the initial state, the peeling assembly 4 has a gap in the vertical direction with the transmission belt 2, so that it will not contact the workpiece 7 when it moves towards the tape 8, thereby avoiding damage to the workpiece 7 and preventing the workpiece 7 from shifting. When the control assembly 3 drives the peeling assembly 4 to move above the tape 8, it can drive the peeling assembly 4 to descend and make contact with the tape 8, so that the tape 8 is adhered to the peeling assembly 4. Then, the control assembly 3 can drive the peeling assembly 4 to reset forward. During the reset process, the tape 8 drives the sheet on the substrate to be peeled off synchronously.

[0036] Furthermore, such as Figure 2 As shown, the frame 1 is equipped with a support plate 5 that corresponds to the position of the transmission belt 2 and is movably attached to the control component 3. When the control component 3 is activated and drives the peeling component 4 to move above the tape 8, it can simultaneously drive the support plate 5 to rise. At this time, the support plate 5 can be attached to the bottom of the transmission belt 2, thereby achieving stable support for the transmission belt 2. This avoids the peeling component 4 from being affected by the elastic deformation of the transmission belt 2 when it descends and the tape 8 is pasted, ensuring the pasting effect between the peeling component 4 and the tape 8, and also ensuring the movement effect of the sheet when the peeling component 4 and the tape 8 are pasted and reset forward.

[0037] Reference Figures 2 to 5 In this embodiment, preferably, the control component 3 includes a base 301 fixedly installed on the frame 1. The base 301 is divided into two parts, front and rear. A motor 302 is fixedly installed on the front base 301. A round shaft 303 is installed between the output shaft of the motor 302 and the rear base 301. A guide groove is provided on the round shaft 303 to slide and engage with the peeling component 4. When the round shaft 303 rotates, it can drive the peeling component 4 to move back and forth through the guide groove, and it can also drive the peeling component 4 to move up and down through the guide groove.

[0038] Specifically, such as Figure 4As shown, the guide groove includes a first guide groove 304 and a second guide groove 305 connected on both sides. The depth dimension of the first guide groove 304 based on the circular shaft 303 is smaller than the depth dimension of the second guide groove 305 based on the circular shaft 303. The connection point of the first guide groove 304 and the second guide groove 305 has a chamfer to facilitate transfer. In the initial state, the peeling component 4 is located at the starting point of the first guide groove 304, and the circular shaft 303 moves along the starting point of the first guide groove 304 towards the ending point when it rotates, which can drive the peeling component 4 to move backward. When the circular shaft 303 rotates 180 degrees, the peeling component 4 is located at the starting point of the second guide groove 305. At this time, the peeling component 4 enters the second guide groove 305 based on the lower part of the circular shaft 303 from the first guide groove 304 based on the higher part of the circular shaft 303. Therefore, the peeling component 4 can descend vertically and form contact and adhesion with the tape 8.

[0039] Furthermore, such as Figure 5 As shown, a cam 306 that movably fits against the support plate 5 is also fixedly installed on the outer surface of the round shaft 303. The cam 306 has a convex surface and a flat surface. The two sides of the flat surface correspond to the two sides of the first guide groove 304, and the two sides of the convex surface correspond to the two sides of the second guide groove 305. This ensures that when the peeling assembly 4 moves towards the tape 8, the support plate 5 will not contact the bottom of the transmission belt 2, thus avoiding contact interference with the transmission belt 2 and reducing frictional damage to the transmission belt 2. When the peeling assembly 4 moves to correspond with the tape 8 and resets after being pasted with the tape 8, the support plate 5 can rise to support the transmission belt 2, ensuring the stable horizontal state of the transmission belt 2.

[0040] Reference Figures 2 to 4 In this embodiment, preferably, the peeling assembly 4 includes a cantilever 401 slidably mounted on the front base 301. The cantilever 401 has a U-shaped design and two ends. The first end is slidably sleeved on the front base 301, and the second end is fixedly mounted with a roller 402. The roller 402 can rotate freely based on the second end of the cantilever 401 itself. An insert 403 is rotatably mounted on the first end of the cantilever 401 and slidably mounted in the first guide groove 304. When the round shaft 303 rotates, it can drive the cantilever 401 and the roller 402 to move towards the tape 8 through the first guide groove 304 and the insert 403.

[0041] Correspondingly, a vertical groove (not labeled in the figure) can be provided on the front base 301 for the sliding placement of the cantilever 401. The cantilever 401 can move back and forth and up and down based on the base 301. Specifically, two locking blocks (not shown in the figure) can be slidably installed in the vertical groove. The first locking block slides up and down with the vertical groove, and the second locking block slides back and forth with the first locking block. The second locking block is fixedly connected to the cantilever 401.

[0042] In the above structure, in the initial state, there is a gap between the lowest point of the roller 402 and the top of the transmission belt 2. This allows the roller 402 to maintain the gap and move towards the tape 8 as the insert 403 moves along the first guide groove 304. Because the depth of the first guide groove 304 based on the circular shaft 303 is smaller than that of the second guide groove 305, the roller 402 can move towards the tape 8 while maintaining the gap. When the roller 402 moves to the corresponding position above the tape 8, the insert 403 enters the second guide groove 305 from the first guide groove 304 and moves downward. The insert 403 drives the roller 402 to descend synchronously through the cantilever 401, causing the roller 402 to adhere to the tape 8. Figure 6 The state shown in the image.

[0043] Reference Figures 2 to 5 In this embodiment, preferably, the support plate 5 includes a sliding plate 503 that slides vertically with the rear base 301. A side plate 502 that movably engages with the cam 306 is fixedly mounted on the surface of the sliding plate 503. A circular plate 501 is fixedly mounted on the surface of the side plate 502 away from the sliding plate 503. Both the side plate 502 and the circular plate 501 are vertically aligned with the transmission belt 2. When the side plate 502 and the circular plate 501 rise, the transmission belt 2 is formed. Figure 2 The support area 201 is shown in the figure.

[0044] It should be noted that the area corresponding to the circular plate 501 is the area where the workpiece 7 is placed. When the workpiece 7 moves with the transmission belt 2, the conveyor belt 8 is located above both the circular plate 501 and the side plate 502. When the roller 402 moves to be vertically aligned with the conveyor belt 8, it is also located on the side of the workpiece 7 closest to the slide plate 503. That is, when the roller 402 descends and contacts the conveyor belt 8, the roller 402 and the workpiece 7 are staggered and there is no contact area between them. At this time, the roller 402 can be located at the junction of the circular plate 501 and the side plate 502, or mostly located on one side of the side plate 502. As long as it is not mostly located on one side of the circular plate 501, it will not contact the workpiece 7 and cause compression.

[0045] Among them, such as Figure 5 As shown, when the insert 403 is located in the first guide groove 304, the plane of the cam 306 contacts the side plate 502. At this time, the side plate 502, the slide plate 503 and the circular plate 501 drop due to gravity and form a gap with the bottom of the transmission belt 2. When the insert 403 is located in the second guide groove 305, the convex surface of the cam 306 contacts the side plate 502 and drives the side plate 502 and the circular plate 501 to rise. At this time, the side plate 502 and the circular plate 501 are in active contact with the bottom of the transmission belt 2 and form a corresponding support area 201.

[0046] In the above structure, the staggered design of the roller 402 and the workpiece 7 avoids wrinkles caused by the height difference between the sheet, roller 402 and tape 8 after they are pasted with tape 8. This ensures that the roller 402 can form a completely flat state after it descends and contacts tape 8. At the same time, it also avoids squeezing damage to the sheet and substrate when the roller 402 descends, ensuring the overall quality stability of workpiece 7 and ensuring that the sheet can be easily peeled off by tape 8 after the roller 402 is reset.

[0047] In use, the transmission belt 2 moves the workpiece 7 to a position corresponding to the roller 402 and then stops. The motor 302 starts, driving the circular shaft 303 and the cam 306 to rotate synchronously. At this time, the insert 403 moves along the first guide groove 304 to the second guide groove 305, and its plane is in contact with the side plate 502. During this process, the roller 402 is located above the transmission belt 2 and moves towards the belt 8, while the circular plate 501 is located below the transmission belt 2. Then, when the insert 403 enters the second guide groove 305, because the depth of the second guide groove 305 is greater than that of the first guide groove 304, the insert 403 drives the cantilever. 401 descends vertically, causing roller 402 to adhere to tape 8. At this time, the convex surface adheres to side plate 502, causing side plate 502 and circular plate 501 to rise and support transmission belt 2. Then, when insert 403 resets along the second guide groove 305 to the first guide groove 304, roller 402 moves forward while maintaining its descending state. The adhered tape 8 drives the sheet on workpiece 7 to be wound onto roller 402 to complete the peeling. After entering the first guide groove 304, insert 403 can drive roller 402 to rise again, restoring the vertical separation state from transmission belt 2, making it easy to remove sheet from roller 402.

[0048] In summary, through the cooperation of the first guide groove 304, the second guide groove 305, the round shaft 303 and the cantilever 401, the roller 402 can be driven to move back and forth and up and down. When moving backward (closer to the conveyor belt 8), the roller 402 is in an upward state, which can effectively reduce frictional damage to the workpiece 7 by offsetting it from the transmission belt 2, and can also avoid contact with the workpiece 7 to prevent it from shifting its position, thereby ensuring the correct contact between the roller 402 and the conveyor belt 8.

[0049] Next, as the roller 402 moves backward into position, it can automatically descend and adhere to the tape 8. At this time, the roller 402 and the workpiece 7 are staggered, which can avoid the height difference between the sheet, the roller 402 and the substrate causing wrinkles in the tape 8 after adhesion. It can also avoid the extrusion damage to the sheet and the substrate when the roller 402 descends, which can ensure the overall quality stability of the workpiece 7 and ensure the smooth peeling of the sheet when the roller 402 is reset later.

[0050] Then, as it moves forward, the sheet can be quickly peeled off from the substrate by the tape 8, while the substrate remains on the conveyor belt 2. When the roller 402 is guided to move by the first guide groove 304 and the second guide groove 305 to complete the peeling, the movement and peeling process of the roller 402 is smoother; the overall peeling efficiency is higher, and it is convenient for subsequent reprocessing of the substrate and sheet. Integrating the structure on the frame 1 makes it easy to arrange and maintain, and has higher practicality.

[0051] Meanwhile, through the cooperation of structures such as the round shaft 303, cam 306, side plate 502 and round plate 501, when the roller 402 moves backward, the side plate 502 and round plate 501 do not rise, so as not to affect the movement of the transmission belt 2 or cause its wear. When the roller 402 moves backward and forward, the side plate 502 and round plate 501 can rise to support the transmission belt 2. At this time, the roller 402 can form an effective bond with the tape 8, avoiding bending and deformation of the transmission belt 2 and affecting the bonding effect. When the roller 402 moves forward to peel off the sheet, the transmission belt 2 is supported so that the substrate always remains horizontal. Therefore, the tearing damage of the sheet separating from the substrate can be effectively reduced, ensuring the peeling quality of the sheet.

[0052] As a further improvement to this embodiment: considering that the roller 402 is always in a descending state when it is reset, when the sheet is peeled off and wound on the roller 402 and moves with the roller 402, the sheet may rub against the transmission belt 2 and cause damage; therefore, as Figure 7 As shown, the second guide groove 305 is improved as follows: the second guide groove 305 includes a first inclined groove 3051 and a second inclined groove 3052 that are connected to each other. The opposite sides of the first inclined groove 3051 and the second inclined groove 3052 are respectively connected to the two sides of the first guide groove 304. The depth dimension of the second inclined groove 3052 based on the circular shaft 303 is equal to the depth dimension of the first guide groove 304 based on the circular shaft 303. Then, after the insert 403 moves along the first inclined groove 3051 into the second inclined groove 3052, the insert 403 can drive the roller 402 and the peeled sheet to rise. At this time, the sheet is completely separated from the transmission belt 2 to avoid damage, and the transmission belt 2 can also start immediately to complete the conveying of the next workpiece 7. At this time, the overall peeling efficiency is further improved.

[0053] Correspondingly, the convex surface of the cam 306 can be reduced while the flat surface can be increased, so that the increased flat surface corresponds to the first guide groove 304 and the second inclined groove 3052, and the reduced convex surface corresponds to the first inclined groove 3051. This allows the side plate 502 and the circular plate 501 to immediately separate from the transmission belt 2 after the roller 402 rises, so that the transmission belt 2 will not be worn immediately after the transmission belt 2 starts.

[0054] Example 2:

[0055] Please see Figures 1 to 10Based on Embodiment 1, in order to further improve the adhesion between the tape 8 and the roller 402, a top plate 6 is fixedly installed on the side plate 502, and an opening 202 adapted to the size of the top plate 6 is provided on the transmission belt 2. When the side plate 502 and the circular plate 501 rise to support the transmission belt 2, the top plate 6 extends out from the opening 202 and lifts the tape 8, thereby allowing the roller 402 to fall and form an effective adhesion with the lifted tape 8. At this time, the area of ​​the tape 8 adhered to the roller 402 is larger, resulting in a better peeling effect of the sheet.

[0056] Furthermore, such as Figure 10 As shown, the top of the top plate 6 has an arc-shaped surface 601. The center of the virtual circle corresponding to the arc-shaped surface 601 is concentric with the center of the roller 402 after it descends. At the same time, when the top plate 6 rises with the side plate 502, the low point of the arc-shaped surface 601 coincides with the top surface of the transmission belt 2, and the low point of the arc-shaped surface 601 also coincides with the lowest point of the roller 402 after it descends. When the roller 402 descends, the arc-shaped surface 601 is completely attached to the outer surface of the roller 402, so that the tape 8 and the outer surface of the roller 402 are completely attached, and the area of ​​complete attachment is larger and the effect is better.

[0057] It should be noted that, as Figure 10 As shown, when the side plate 502 and the circular plate 501 are in a descending state and separated from the transmission belt 2, the top plate 6 is also below the transmission belt 2. At this time, the top plate 6 will not interfere with the transmission belt 2's conveying of the workpiece 7. When the side plate 502 rises later, the top plate 6 can extend from the opening 202 to complete the bending guidance of the tape 8.

[0058] In use, the roller 402 can be driven to move back and forth and up and down through the first guide groove 304, the second guide groove 305, the round shaft 303, and the cantilever 401, thus completing the sheet peeling process. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference is that when the roller 402 moves backward into position, it automatically descends. At this time, the side plate 502 and the round plate 501 rise through the convex surface of the cam 306 and fit against the bottom of the transmission belt 2, while the top plate 6 extends out from the opening 202 of the transmission belt 2. After the top plate 6 extends, it can bend and guide the tape 8 extending from the workpiece 7. After the roller 402 descends, it is completely fitted with the arc surface 601 of the top plate 6. At this time, the tape 8 that is bent and extending from the workpiece 7 can be completely fitted against the outer surface of the roller 402, which can ensure the adhesion effect between the tape 8 and the roller 402, thereby ensuring the sheet peeling effect when the roller 402 returns to its forward position.

[0059] Compared to Embodiment 1, through the cooperation of structures such as side plate 502, top plate 6, arc surface 601 and opening 202, the top plate 6 can extend from the opening 202 so that the arc surface 601 fits with the descending roller 402. At this time, the arc surface 601 is used to bend and guide the tape 8 of the extended workpiece 7, and at the same time, it can make more tape 8 stick to the outer surface of the roller 402. At this time, the bonding area between the tape 8 and the roller 402 is larger, so the subsequent peeling effect of the sheet is better.

[0060] The overall design is combined with the movement of the side plate 502, so that the top plate 6 can descend with the side plate 502 and separate from the transmission belt 2. At this time, the top plate 6 will not interfere with the transmission belt 2 to transport the workpiece 7, which can ensure the orderly peeling of the sheet. At the same time, the insertion of the top plate 6 into the opening 202 also has the purpose of stabilizing and orienting the transmission belt 2, so the overall functionality is stronger.
