Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, and specifically relates to a photovoltaic module frame removal device. Background Technology

[0002] As is well known, a photovoltaic module includes an enclosing frame, an upper glass cover plate located inside the frame and arranged vertically, solar cells, a lower base plate, and a junction box. The frame includes a long side and a short side located on both sides, and the frame is sealed to the upper glass cover plate and the lower base plate with sealant. At the same time, the junction box is also positioned on the upper glass cover plate with sealant.

[0003] Currently, whenever photovoltaic (PV) modules encounter problems during processing and require factory repair, or when they need to be recycled after retirement, the frames and junction boxes must be removed. Most PV module frame removal equipment on the market uses an external support method. For example, Chinese patent CN112497165A discloses a PV panel frame removal device, comprising a frame body, a workbench, a clamping mechanism, a short frame removal device, a long frame removal device, and an electrical control system. The frame body includes a support frame and a gantry frame mounted on the support frame. The workbench is installed on the support frame below the gantry frame. The clamping mechanism is installed on the gantry frame opposite the workbench and can move up and down relative to the gantry frame. The short frame removal device is installed on the gantry frame and can move relative to the gantry frame in a first direction and also move up and down relative to the gantry frame. The long frame removal device is installed on the support frame and can move relative to the support frame in a first direction. The electrical control system connects the clamping mechanism, the short frame removal device, and the long frame removal device, and is used to control their movement.

[0004] However, in the actual dismantling process, when the existing technology uses a frame removal wheel to remove the long frame, the end of the long frame lacks constraint as the frame removal wheel moves. As the part of the long frame that is peeled off from the component gradually becomes longer and twists outward, it occupies a large space and is prone to changes in the peeling angle of the long frame, making it difficult to maintain the stability of the peeling quality and increasing the probability of the long frame falling and deforming, thus causing component deformation problems. In addition, the success rate of automatic detachment and recycling of the peeled long frame is low. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an improved photovoltaic module frame removal device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A photovoltaic module frame removal device includes a short-side removal unit and a long-side removal unit formed at the frame removal station. The long-side removal unit includes a side support wheel module for gradually supporting the long frame from the first end, and a moving module for driving the side support wheel module to move from the first end to the last end of the long frame. The long-side removal unit also includes a first-end auxiliary module that is linked with the side support wheel module. The first-end auxiliary module includes a constraint seat for constraining the first end of the long frame, and a shifter that drives the constraint seat to move inward to match the peeling angle formed by the side support wheel module. The peeling point formed by the side support wheel module is located inside the constraint point formed by the constraint seat. As the peeling point moves forward to the last end, the constraint point moves inward. When the long frame removal is completed, the peeling point and the constraint point are aligned with the long side of the module as a reference.

[0008] According to a specific embodiment and preferred aspect of the present invention, the constraint seat includes a seat body forming a grid surface from its inner wall, a constraint rod disposed on the inner side of the grid surface, and a constraint power unit. The side support wheel module supports the first end of the long frame outward and abuts against the grid surface. The constraint rod then constrains the first end of the long frame in the short side direction, and as the peeling point moves forward towards the end, the first end of the long frame can move freely in the long side direction. Here, it is convenient to accurately control the initial peeling angle of the long frame, improving the peeling quality; at the same time, it is convenient to accurately constrain the first end of the long frame, and based on the free movement of the first end of the long frame in the long side direction, stress can be gradually released synchronously during peeling.

[0009] Preferably, the constraint actuator includes a first power member that drives the constraint rod to align or misalign with the grid surface in the short side direction of the component, and a second power member that drives the constraint rod aligned with the grid surface to move closer to or further away from the grid surface in the short side direction of the component to constrain or loosen the first end of the long frame.

[0010] Preferably, the constraint rod extends along the long side of the component, and the first power member drives the constraint rod to extend and retract along the long side of the component. When constrained, the constraint rod extends out, inserts into, and supports the inner side of the first end of the long frame. This improves the support for the first end of the long frame, reduces deformation, and facilitates the quick release and dismantling of the long frame based on the extension and retraction movement of the constraint rod.

[0011] According to another specific embodiment and preferred aspect of the invention, as the peeling point and the constraint point align, the long frame synchronously shifts forward relative to the long side of the component. This not only facilitates precise cutting of the long frame after removal, but also effectively reduces the probability of residual adhesive adhering between the long frame and the component based on the forward movement of the long frame during removal.

[0012] According to another specific embodiment and preferred aspect of the invention, during disassembly, based on the coordinated movement of the constraint seat confining the first end of the long frame inward and the side support wheel module moving forward, a force is simultaneously generated at the peeling point to drive the long frame outward to peel off the component. Here, similar to the lever principle, based on the fulcrum formed by the side support wheel module, the constraint seat confining the first end of the long frame inward generates a force at the peeling point to drive the long frame outward to peel off, thereby assisting in the rapid peeling of the long frame from the component.

[0013] Preferably, the side support wheel module includes a side support wheel assembly and a driver. When the side support wheel assembly approaches the beginning of the long frame, the driver drives the side support wheel assembly to support the long frame and form a peeling angle. The peeled long frame bypasses the side support wheel assembly and is constrained to the constraint seat from its beginning. Here, compared to the traditional side support wheel assembly that directly moves along the long side of the component for peeling, this application first drives the side support wheel assembly to support the long frame quickly to form a peeling angle, and then constrains the beginning of the long frame with the peeling angle before proceeding with the subsequent peeling. This not only reduces the probability of wear and deformation caused by the side support wheel assembly instantaneously contacting the long frame and extends its service life, but also facilitates the precise constraint of the beginning of the long frame by the constraint seat.

[0014] Specifically, the side support wheel assembly includes a first side support wheel and a second side support wheel that are staggered from front to back and from inside to outside.

[0015] Preferably, the side support wheel module further includes a guide component, which includes a support module disposed in front of the side support wheel assembly and an auxiliary pressure roller disposed above the support module. The support module forms a horizontal support surface from the top and a guide surface extending forward and downward from the front end of the support surface. During removal, the bottom of the peeling portion of the long frame rests on the support surface, and the auxiliary pressure roller presses against the top of the peeling portion of the long frame. Here, the long frame can be precisely peeled off by making contact with the side support wheel assembly based on the guiding cooperation of the support module and the auxiliary pressure roller.

[0016] Preferably, the side support wheel module further includes a pressing component, which includes a pressure roller disposed above the guide surface and a pressing power component that drives the pressure roller to move up and down. As the peeling point moves forward towards the end, the long frame passes between the auxiliary pressure roller and the support surface based on the cooperation of the pressure roller and the guide surface. Here, for the long frame that has been deformed, the pressure roller flattens it and it passes between the support surface and the auxiliary pressure roller through the guide surface.

[0017] According to another specific embodiment and preferred aspect of the present invention, the short-side removal unit includes a top frame module and a drive module for driving the top frame module to support the short side frame. The top frame module includes two main top frame modules spaced apart along the short side direction of the component, a plurality of auxiliary top frame modules spaced apart between the two main top frame modules along the short side direction of the component, and an adjuster for adjusting the spacing between the two main top frame modules to match the length of the short side frame. Here, by adjusting the spacing between the main top frame modules to perform external support peeling close to both ends of the short side frame, the separation of the connection points between the two ends of the short side frame and the long side frame is ensured, improving the success rate of short side frame peeling and flexibly matching the removal requirements of short side frames of different specifications. Simultaneously, the cooperation of the main and auxiliary top frame modules ensures uniform stress on the short side frame, reducing the probability of deformation.

[0018] Preferably, each main top frame module has a pushing surface opposite to the short frame, and each main top frame module has an extension portion that gradually thins towards the adjacent long frame from one side. During adjustment, each main top frame module is inserted into the gap between the adjacent long frame and the component surface from the extension portion, and as each main top frame module supports the short frame, the extension portion simultaneously cleans the adhesive layer between the beginning of the long frame and the component surface. Here, when removing the short frame, the adhesive layer between the beginning of the long frame and the component surface can be cleaned simultaneously, thereby reducing the difficulty of peeling off the beginning of the long frame and reducing the probability of component displacement or deformation during removal of the long frame.

[0019] Preferably, the short-side removal unit further includes a baffle module, which comprises multiple vertical baffles located outside the top frame module and multiple horizontal baffles located above the top frame module. During removal, the vertical baffles, horizontal baffles, and the top frame module work together to confine the short side frame at the removal station. Here, the short side frame may release significant stress at the moment of peeling off the short side of the component, causing it to fly off. The baffle module of this application can effectively suppress the short side frame from flying off, thus facilitating accurate collection.

[0020] In addition, the short side removal unit also includes an unloading module, which includes multiple unloading modules spaced apart along the short side of the component and an unloading power component that drives the multiple unloading modules to reciprocate along the long side of the component. When the short frame is removed from the component, the unloading power component drives the multiple unloading modules to push the short frame outward to the frame removal station simultaneously.

[0021] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0022] When using a frame removal wheel to remove long frames, the ends of the long frames lack constraint as the frame removal wheel moves. As the part of the long frame being peeled off from the component gradually lengthens and twists outward, it occupies a large space and easily causes changes in the peeling angle of the long frame, making it difficult to maintain stable peeling quality and increasing the probability of the long frame sagging and deforming, thus causing component deformation problems. In addition, the success rate of automatic detachment and recycling of the peeled long frame is low. This application provides an overall design for the structure of the photovoltaic module frame removal device, cleverly addressing the shortcomings and defects of existing technologies. Using this photovoltaic module frame removal device, the module is transferred to the frame removal station. After the short side is removed, the side support wheel module gradually supports the long frame from the beginning, and the constraint seat constrains the beginning of the long frame to form a constraint point. As the peeling point formed by the side support wheel module moves towards the end of the long frame, the shifter drives the constraint seat to move inward, causing the constraint point to follow inward to match the peeling angle formed by the side support wheel module. When the long frame removal is complete, the peeling point and the constraint point are aligned with the long side of the module, allowing the module to be peeled off while the long frame remains flat for recycling. Therefore, compared with the prior art, the present invention, on the one hand, through the coordinated movement of the constraint seat and the side support wheel module, gradually peels the long frame from the component while maintaining a consistent peeling angle, significantly reducing the probability of the long frame causing deformation of the component during peeling and effectively improving the stability of peeling quality; on the other hand, by keeping the peeling point and constraint point aligned with the long side of the component as a reference, the flatness of the long frame after removal is improved, which not only saves the space for frame removal, but also greatly improves the success rate of long frame removal and recycling.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] like Figures 1 to 8 As shown, the photovoltaic module frame removal device involved in this embodiment includes a short side removal unit 1 and a long side removal unit 2 formed at the frame removal station W; the photovoltaic module G involved in this embodiment has a long frame K1 and a short frame K2 assembled on its long and short sides respectively, and the short side removal unit 1 and the long side removal unit 2 each have two sets corresponding to the short frame K2 and long frame K1 on the front and rear sides and the left and right sides of the module.

[0041] Specifically, the short side removal unit 1 includes a top frame module 10, a drive module 11 that drives the top frame module 10 to support the short side frame K2, a stop module 12, and an unloading module 13.

[0042] The top frame module 10 includes two main top frame modules 100 spaced apart along the short side (i.e., left-right) of component G, multiple auxiliary top frame modules 101 spaced apart between the two main top frame modules 100 along the short side of component G, and an adjuster 102 for adjusting the spacing between the two main top frame modules 100 to match the length of the short frame. Here, by adjusting the spacing of the main top frame modules to perform external support peeling closer to the ends of the short frame, the separation of the ends of the short frame from the connection points of the long frame is ensured, improving the success rate of short frame peeling and flexibly matching the removal requirements of short frames of different specifications; simultaneously, the cooperation of the main and auxiliary top frame modules ensures uniform stress on the short frame, reducing the probability of deformation.

[0043] For ease of implementation, each main top frame module 100 and auxiliary top frame module 101 has a pushing surface m0 opposite to the short frame K2, and each main top frame module 100 has an extension b that gradually thins towards the adjacent long frame K1 from one side. During adjustment, each main top frame module 100 inserts from the extension b into the gap between the adjacent long frame K1 and the surface of the component G. As each main top frame module 100 supports the short frame K2, the extension b simultaneously cleans the adhesive layer between the beginning of the long frame K1 and the surface of the component G. Here, when removing the short frame, the adhesive layer between the beginning of the long frame and the surface of the component can be cleaned simultaneously, thereby reducing the difficulty of peeling the beginning of the long frame and reducing the probability of component displacement or deformation during removal of the long frame.

[0044] Furthermore, the external support of the extension b can also reduce deformation at the point where the short frame K2 and the long frame K1 interlock, so as to facilitate precise peeling.

[0045] Meanwhile, the pushing surfaces m0 of the main top frame module 100 and the auxiliary top frame module 101 are offset from the inside to the outside. That is to say, when the short frame K2 is supported, the pushing surfaces m0 of the main top frame module 100 and the auxiliary top frame module 101 gradually push it from both ends of the short frame K2 towards the middle. In other words, the two ends of the short frame K2 that form a plug-in fit with the ends of the two long frames K1 on both sides are pushed out first, and then the middle of the short frame K2 is pushed out. The advantage of this setting is that, based on the stress of the short frame itself, under the deformation of the ends being pushed outward, an auxiliary force can be formed to help the peeling component in the middle of the short frame, reducing the difficulty of removing the short frame and improving the success rate of peeling.

[0046] The regulator 102 includes two adjusting seats 1020 arranged side by side with a spacing between them, and an adjusting power component 1021. The two adjusting seats 1020 each have racks extending to the left and right respectively. The adjusting power component 1021 is a motor that meshes with the two racks through a transmission gear from its output shaft. Two main top frame modules 100 are correspondingly arranged on the two adjusting seats 1020. As the adjusting power component 1021 drives, the two adjusting seats 1020 move in opposite directions to adjust the distance between the two main top frame modules 100.

[0047] In this example, drive module 11 uses a conventional power screw drive mechanism.

[0048] In this example, the material-blocking module 12 includes multiple vertical material-blocking rods 120 disposed on the outside of the top frame module 10 and multiple horizontal material-blocking rods 121 disposed above the top frame module 10. During disassembly, the vertical material-blocking rods 120, the horizontal material-blocking rods 121, and the top frame module 10 cooperate to confine the short frame K2 to the disassembly station W. Here, the short frame may release significant stress at the moment of peeling off the short side of the component, causing the short frame to be thrown out. The material-blocking module of this application can effectively suppress the phenomenon of the short frame being thrown out, thereby facilitating accurate collection.

[0049] To further facilitate implementation, multiple vertical baffles 120 are driven to move up and down by a lifting power component to avoid unloading the dismantled short frame K2.

[0050] In this example, the unloading module 13 includes multiple unloading modules 130 spaced apart along the short side of the component, and an unloading power unit 131 that drives the multiple unloading modules 130 to reciprocate along the long side (i.e., the front-to-back direction) of the component. When the short frame K2 is removed from the component, the unloading power unit 131 drives the multiple unloading modules 130 to simultaneously push the short frame K2 outwards to the frame removal station W. Each unloading module 130 is located between adjacent main and / or auxiliary top frame modules and uses a spring clip.

[0051] In this example, the long side removal unit 2 includes a side support wheel module 20 for gradually supporting the long side frame K1 from the first end, a moving module 21 for driving the side support wheel module 20 to move from the first end to the last end of the long side frame K1, and a first end auxiliary module 22 that is linked with the side support wheel module 20.

[0052] In some specific embodiments, the side support wheel module 20 includes a side support wheel assembly 200, a driver 201, a guide component 202, and a pressing component 203. When the side support wheel assembly 200 approaches the first end of the long frame K1, the driver 201 drives the side support wheel assembly 200 to support the long frame and form a peeling angle. The peeled long frame K1 bypasses the side support wheel assembly 200 and is constrained from its first end to the first end auxiliary module 22. Here, compared with the traditional side support wheel assembly that directly moves along the long side of the component for peeling, this application first drives the side support wheel assembly to support the long frame to quickly form a peeling angle, and then constrains the first end of the long frame that has formed the peeling angle before performing subsequent peeling. This not only reduces the probability of wear and deformation caused by the side support wheel assembly instantaneously contacting the long frame and extends its service life, but also facilitates the precise constraint of the first end of the long frame by the constraint seat. It should be noted that after the peeling angle is formed, the driver 201 stops driving, that is, the side support wheel assembly 200 maintains a linear displacement for peeling the long frame.

[0053] The side support wheel assembly 200 of this embodiment includes a first side support wheel 2001 and a second side support wheel 2002 arranged in a staggered manner from front to back and from inside to outside.

[0054] In this example, the driver 201 can be any conventional linear drive mechanism that drives the side support wheel assembly 200 to move laterally left and right, which will not be elaborated here. The guide component 202 includes a support module 2020 disposed in front of the side support wheel assembly 200 and an auxiliary pressure roller 2021 disposed above the support module 2020. The support module 2020 forms a horizontal support surface m1 from the top and a guide surface m2 extending forward and downward from the front end of the support surface m1. During removal, the bottom of the peeled portion of the long frame K1 is supported on the support surface m1, and the auxiliary pressure roller 2021 presses against the top of the peeled portion of the long frame K1. Here, the long frame can be peeled off precisely by making contact with the side support wheel assembly based on the guiding cooperation of the support module and the auxiliary pressure roller.

[0055] In this example, the pressing component 203 includes a pressure roller 2030 disposed above the guide surface m2 and a pressing power component 2031 that drives the pressure roller 2030 to move up and down. As the peeling point formed by the side support roller assembly 200 moves forward toward the end of the long frame K1, the long frame K1 passes between the auxiliary pressure roller 2021 and the support surface m1 based on the cooperation of the pressure roller 2030 and the guide surface m2. Here, for the long frame that has been deformed, the pressure roller flattens it and it passes between the support surface and the auxiliary pressure roller through the guide surface.

[0056] In this example, the moving module 21 includes a slide rail 210 extending forward and backward, a slide block 211 slidably connected to the slide rail 210, and a drive member 212 that drives the slide block 211 to reciprocate along the slide rail 210. The side support wheel module 20 is disposed on the slide block 211. The slide rail 210 has a rack. The drive member 212 uses a motor and has a transmission gear that meshes with the rack on its output shaft for linear drive.

[0057] In this example, the first-end auxiliary module 22 includes a constraint seat 220 for constraining the first end of the long frame K1, and a shifter 221 that drives the constraint seat to move the long frame K1 inward so as to match the peeling angle formed by the side support wheel module 20. The peeling point formed by the side support wheel module 20 is located inside the constraint point formed by the constraint seat 220. As the peeling point moves forward toward the end of the long frame K1, the constraint point moves inward. When the long frame K1 is removed, the peeling point and the constraint point are aligned with the long side of the component as the reference.

[0058] In some specific embodiments, the constraint seat 220 includes a seat body 2200 forming a grid surface m3 from its inner wall, a constraint rod 2201 disposed on the inner side of the grid surface m3, and a constraint power unit 2202. The side support wheel module 20 supports the first end of the long frame K1 outward and abuts against the grid surface m3. The constraint rod 2201 then constrains the first end of the long frame K1 in the short side direction. As the peeling point moves forward towards the end, the first end of the long frame K1 can adaptively move freely in the long side direction. This facilitates precise control of the initial peeling angle of the long frame, improving peeling quality; it also facilitates precise constraint of the first end of the long frame, and based on the free movement of the first end of the long frame in the long side direction, stress can be gradually released synchronously during peeling.

[0059] To further facilitate implementation, the constraint seat 220 is slidably connected to the slide rail 210 via an auxiliary slide seat z and can slide back and forth to ensure that the first end of the long frame K1 extends into the constraint area of ​​the constraint seat 220. The driving principle of the auxiliary slide seat z is similar to that of the slide seat 211, and will not be described in detail here. The cross-section of the constraint rod 2201 is circular to reduce the contact area with the long frame when forming the constraint and reduce friction.

[0060] In this example, the constraint rod 2201 extends along the long side of the component, and the constraint power unit 2202 includes a first power member d1 that drives the constraint rod 2201 to align or misalign with the grid surface m3 in the short side of the component, and a second power member d2 that drives the constraint rod 2201 aligned with the grid surface m3 to move closer to or further away from the grid surface m3 in the short side of the component to constrain or loosen the first end of the long frame. The first power member d1 and the second power member d2 are both conventional linear drive mechanisms.

[0061] In some specific embodiments, the first power member d1 drives the constraint rod 2201 to extend and retract along the long side of the component. During constraint, the constraint rod 2201 extends out, inserts into, and supports the inner side of the first end of the long frame K1. This improves the support for the first end of the long frame, reduces deformation, and facilitates the rapid release of the dismantled long frame based on the extension and retraction movement of the constraint rod.

[0062] To further facilitate implementation, as the peeling point and constraint point align, the long frame K1 synchronously shifts forward relative to the long side of the component to align with the long frame unloading port on the W side of the disassembly station. This not only facilitates accurate unloading of the disassembled long frame but also effectively reduces the probability of residual adhesive adhering between the long frame and the component, based on the forward movement of the long frame during disassembly.

[0063] Simultaneously, during dismantling, based on the coordinated movement of the constraint seat 220 constraining the first end of the long frame K1 and moving it inward, and the side support wheel module 20 moving forward, the peeling point synchronously generates a force that drives the long frame K1 to peel the component outward. Here, similar to the lever principle, based on the fulcrum formed by the side support wheel module, the constraint seat constrains the first end of the long frame to move inward, thereby generating a force at the peeling point that drives the long frame to peel outward, thus assisting in the rapid peeling of the long frame from the component.

[0064] Furthermore, the driving principle of shifter 221 is similar to that of drive unit 212, and will not be elaborated here.

[0065] In summary, after adopting this photovoltaic module frame removal device, the module is transferred to the frame removal station. After the short side is removed, the side support wheel module gradually supports the long frame from the beginning, and the constraint seat constrains the beginning of the long frame to form a constraint point. As the peeling point formed by the side support wheel module moves forward to the end of the long frame, the shifter drives the constraint seat to move inward and causes the constraint point to move inward to match the peeling angle formed by the side support wheel module. When the long frame is removed, the peeling point and the constraint point are aligned with the long side of the module as the reference, so that the module is peeled off while the long frame is flat and recycled. Therefore, compared with the prior art, this invention, on the one hand, through the coordinated movement of the constraint seat and the side support wheel module, gradually peels the long frame from the component while maintaining a consistent peeling angle, significantly reducing the probability of deformation of the component caused by the long frame during peeling, and effectively improving the stability of peeling quality; on the other hand, by keeping the peeling point and constraint point aligned with the long side of the component as a reference, it improves the flatness of the long frame after removal, not only saving disassembly space but also greatly increasing the success rate of long frame detachment and recycling; thirdly, it facilitates precise control of the initial peeling angle of the long frame, improving peeling quality; and also facilitates... The fourth aspect is the precise constraint of the long frame's leading edge; similar to the lever principle, based on the fulcrum formed by the side support wheel module, the constraint seat constrains the leading edge of the long frame to move inward, generating a force at the peeling point that drives the long frame to peel outward, thereby assisting in the rapid peeling of the long frame from the component; the fifth aspect is that, compared to the traditional side support wheel assembly that directly moves along the long side of the component for peeling, this application first uses a driver to drive the side support wheel assembly to support outward, causing the long frame to quickly form a peeling angle, and then constrains the leading edge of the long frame that forms the peeling angle before proceeding with the subsequent peeling. This not only reduces the wear caused by the side support wheel assembly's instantaneous contact with the long frame. The deformation probability is reduced, service life is extended, and the constraint seat can accurately constrain the first end of the long frame; sixthly, for the long frame that has already deformed, the pressure roller is used to level it and enter the support surface and auxiliary pressure roller through the guide surface; seventhly, by adjusting the spacing of the main top frame module to approach the two ends of the short frame for external support peeling, the separation of the two ends of the short frame from the connection part of the long frame is ensured, the peeling success rate of the short frame is improved, and the removal requirements of short frames of different specifications are flexibly matched; at the same time, the cooperation of the main and auxiliary top frame modules makes the short frame bear the force evenly and reduces the probability of deformation; eighthly, the short frame is disassembled. In addition to simultaneously cleaning the adhesive layer on the first end of the long frame and the surface of the component, the difficulty of peeling off the first end of the long frame is reduced, and the probability of component displacement or deformation during the removal of the long frame is reduced; in the ninth aspect, the short frame may release a large stress at the moment of peeling off the short side of the component, causing the short frame to be thrown out. The material blocking module of this application can effectively suppress the phenomenon of short frame being thrown out, thus facilitating accurate collection; in the tenth aspect, based on the stress of the short frame itself, under the outward deformation at the end, an auxiliary force can be formed to help peel off the component in the middle of the short frame, reducing the difficulty of removing the short frame and improving the peeling success rate.
