Abstract
Description
Technical Field
[0001] The present invention belongs to the field of photovoltaics, and specifically relates to a photovoltaic high-temperature cloth tearing, recycling and busbar erection and shaping integrated processing process, and also relates to a photovoltaic high-temperature cloth tearing, recycling and busbar erection and shaping integrated processing equipment. Background Art
[0002] Photovoltaic modules are formed into laminates after being stacked in different orders by crystalline silicon cells, tempered glass and packaging materials. During the lamination process, the temperature is increased to melt the EVA film on the upper and / or lower layers of the busbar, so that one end of the busbar is positioned in the laminate, and the other end of the busbar extends out from the lead-out hole of the upper packaging material for subsequent connection and installation with the junction box. In order to prevent the molten EVA glue from overflowing from the lead-out hole during the lamination process and affecting the performance and appearance of the photovoltaic laminate, it is necessary to use high-temperature cloth (also called photovoltaic high-temperature cloth, commonly used such as: polytetrafluoroethylene cloth) before lamination, that is, by attaching to the surface of the photovoltaic laminate and covering the lead-out hole to prevent the EVA glue from overflowing, and at the same time, the busbar passes through the high-temperature cloth and is relatively flattened above the high-temperature cloth. Therefore, after the lamination is completed, the high-temperature cloth needs to be torn off, and the busbar that was bent and attached to the surface of the high-temperature cloth during the lamination process needs to be turned upward (that is, from horizontal to vertical state).
[0003] However, in order to tear off the high-temperature cloth, the clamps are generally used to shovel in and clamp from both ends of the high-temperature cloth, and then the clamps move upward to tear off the high-temperature cloth, and the torn high-temperature cloth needs to be transferred to the recycling belt, and then the clamps are released, and the high-temperature cloth falls into the recycling belt below for recycling. At the same time, the two bus bars can be erected upward during the tearing process, and a shaping mechanism needs to be used to form extrusion shaping from the front and back and left and right directions. Obviously, in the above-mentioned high-temperature cloth and bus bar processing, there are the following defects:
[0004] 1) When the high-temperature cloth is first scraped, then clamped, and then lifted and torn off, the clamping claws are very likely to scratch the photovoltaic laminate and cause damage to the photovoltaic laminate, which reduces the yield of photovoltaic products. In addition, it is difficult to keep the clamping length formed by the clamping claws at both ends consistent. Therefore, in the process of clamping and pulling up, the bending point of the busbar is not the connection point with the photovoltaic module, resulting in the two busbars being uneven in height or the bending point forming a penetration barrier, which affects the installation of the junction box. At the same time, because EVA glue is formed between the high-temperature cloth and the photovoltaic module, if it is pulled forcibly, it will not only damage the surface structure of the photovoltaic module, but also very likely cause the busbar to be deformed or broken by extreme pulling, increasing the difficulty of installation of the subsequent junction box process;
[0005] 2) The resulting shaping is basically in the same dimension, and the relative extrusion shaping of left and right, front and back cannot control the length of the busbar erected. Therefore, at least in terms of the alignment of the erection height, the shaping requirements cannot be met;
[0006] 3) During the high-temperature cloth recovery process, once the high-temperature cloth is entangled or stuck on the clamp (or stuck to the clamp) due to damage, the high-temperature cloth cannot be separated from the clamp by the loosening movement of the clamp. In this way, the unloaded high-temperature cloth remains on the clamp, which directly affects the next tearing operation of the high-temperature cloth and further affects the erection of the busbar. Summary of the invention
[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new integrated process for tearing off, recycling and erecting and shaping busbars of photovoltaic high-temperature cloth.
[0008] At the same time, the present invention also relates to an integrated processing device for tearing off, recycling and erecting and shaping busbars of photovoltaic high-temperature cloth.
[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0010] A photovoltaic high temperature cloth tearing, recycling and busbar erection and shaping integrated processing process, the high temperature cloth extends in the left and right directions and is glued to the surface of the photovoltaic laminate from the lead-out holes on the surface of the photovoltaic laminate, two busbars respectively pass through the high temperature cloth and flatten the high temperature cloth to the left and right, which includes the following steps:
[0011] S1. Removal of high temperature cloth
[0012] (1) Preheating and pre-shoveling
[0013] Use hot air flow from front to back to purge the high-temperature cloth, make the high-temperature cloth relatively fit the busbar, and preheat and soften the glued part at the same time;
[0014] A pre-shovel is used to wedge between the surface of the photovoltaic laminate and the high-temperature cloth from the left and right sides along the forward movement, and the wedging angle gradually decreases as the resistance changes. The high-temperature cloths and bus bars on the left and right sides are both lifted up, and the pre-shovel action is reset with the assistance of the preheated airflow. The high-temperature cloth is attached to the return bar, and the high-temperature cloth emerges from the top of the bus bar from the ends, wherein the emerging lengths are equal, and the high-temperature cloth and the bus bar are arranged symmetrically about the gluing position.
[0015] (2) Shovel and tear upwards
[0016] The shovel clamping claws that move left and right are used to shovel into the bottom of the raised high-temperature cloth, and the protruding end is clamped by the relative movement of the shovel clamping claws, and the high-temperature cloth is peeled upward with the glued part as the center of force, and the busbar is driven upward to stand up while the high-temperature cloth is torn off;
[0017] S2, busbar erection and shaping
[0018] (1) Front, back, left, and right squeeze shaping
[0019] The vertical busbar is relatively straightened and shaped in the left-right and front-back directions by using the extrusion module moving in the front-back and left-right directions with the positioning grid as the reference;
[0020] (2) Up and down pulling and shaping
[0021] The busbar is pulled by a pulling method to calibrate the connection point with the photovoltaic laminate as the erection end point;
[0022] S3. Recycling of high temperature cloth
[0023] The high-temperature cloth clamped by the shovel clamp is transferred to the receiving conveyor belt and the shovel clamp is released. The high-temperature cloth slides freely to the receiving conveyor belt below and is sent to the recovery box. At the same time, the high-temperature cloth sensor verifies whether the high-temperature cloth is separated from the shovel clamp. When it is not separated from the shovel clamp, the position of the shovel clamp is adjusted to align with the fixed brush, and the shovel clamp is brushed by the brush. The high-temperature cloth that has been brushed off is sent to the recovery box by the receiving conveyor belt.
[0024] According to a specific implementation and preferred aspect of the present invention, in step S1 (1), preheating and pre-shoveling are performed simultaneously. Such effective association of preheating and pre-shoveling can at least reduce the damage rate of photovoltaic modules caused by contact between the pre-shovel and the photovoltaic modules during pre-production.
[0025] Furthermore, in step S1 (1), the preheating area is changed synchronously with the pre-shoveling so that the purge airflow can fit the high-temperature cloth to the busbar.
[0026] Furthermore, in step S1 (1), the distance between the preheating airflow outlet and the surface of the photovoltaic laminate is adjusted to change the airflow direction in the preheating area, and as the pre-shoveling is performed, more airflow is swept upward along the shoveling top surface.
[0027] In some specific embodiments, as the pre-shovel is gradually shoveled in, the preheated airflow outlet gradually approaches the surface of the photovoltaic laminate; as the pre-shovel is reset, the preheating is reset synchronously.
[0028] According to another specific implementation and preferred aspect of the present invention, in step S1 (2), the clamping heights formed by the left and right shovel claws are the same. In this way, the pulling forces formed by the left and right are the same, which not only reduces the purpose of tearing the photovoltaic module, but also avoids the probability of inconsistent deformation caused by different forces on the two busbars.
[0029] According to another specific implementation and preferred aspect of the present invention, in step S1 (2), the high-temperature cloth is clamped at the left and right ends and kept in a relatively flattened mode, and then moves upward to gradually tear off the photovoltaic laminate. In short, the shovel clamping claws are in a relative elastic deformation to maintain the high-temperature cloth at the end to form a relative pulling force, and then gradually tear it off in combination with the upward force, so that the tearing not only causes less damage, but also has good tearing quality.
[0030] According to another specific implementation and preferred aspect of the present invention, in step S1 (2), the high temperature cloth is clamped at both ends and the high temperature cloth is relatively opened downward and outward by the relative clamping of the shovel clamping claws. Such a design mainly separates the high temperature cloth and the busbar relatively after clamping, and avoids the high temperature cloth from causing a large deformation of the busbar at the moment of separation due to adhesion during tearing, thereby increasing the difficulty of later shaping.
[0031] In some specific embodiments, when the high temperature cloth is separated from the photovoltaic laminate, the shovel clamps the two ends of the high temperature cloth and rotates inward, and the high temperature cloth is relatively folded downward to form a V-shape or a U-shape. In this way, the shovel clamps the high temperature cloth downward during the relative reset, increasing the probability that the high temperature cloth can be smoothly separated after the shovel clamp is relaxed, thereby facilitating the recovery of the high temperature cloth. At the same time, the high temperature cloth arranged in this way is also conducive to the information acquisition of the photoelectric sensor, avoiding the situation where the unloaded high temperature cloth interferes with the next shoveling of the cloth.
[0032] According to another specific implementation and preferred aspect of the present invention, in step S2, the tearing of the high temperature cloth and the shaping of the busbar are located on the same working die head, and after the high temperature cloth is torn off, the busbar is shaped by moving forward, and after the shaping of the busbar is completed, the high temperature cloth is recycled. In this way, tearing, shaping, and recycling form a set of processes, which increases the processing efficiency of the high temperature cloth and busbar on the surface of the photovoltaic module.
[0033] Preferably, in step S2 (2), the busbar is clamped and then clamped and pulled upwards with the assistance of a shaping module, and the clamping and pulling method is used to form an upward pull straightening.
[0034] Another technical solution of the present invention is: an integrated processing device for tearing off, recycling and erecting and shaping photovoltaic high-temperature cloth (that is, an integrated processing device used in the integrated processing process of tearing off, recycling and erecting and shaping photovoltaic high-temperature cloth), which includes a frame, a truss that can move horizontally along the front and rear directions, a fixed seat installed on the truss, a high-temperature cloth tearing unit, a busbar shaping unit, and a high-temperature cloth recovery unit, wherein the high-temperature cloth tearing unit includes movable clamps located at the left and right ends, and a lifting mechanism that drives the movable clamps to move up and down; the high-temperature cloth recovery unit includes a material receiving conveyor belt consistent with the length direction of the truss, and a recycling box located at the discharge end of the material receiving conveyor belt; the busbar shaping unit includes a clamping and shaping module; the high-temperature cloth tearing unit and the busbar shaping unit are located on the same fixed seat and are arranged in a front-to-back layout; the high-temperature cloth tearing unit also includes a shovel that is arranged at the rear side of the movable clamp and can move forward to scoop up A pre-shoveling component for the high-temperature cloth and the bus bar, a pre-heating and blowing component located on the front side and capable of forming hot air blowing, and a high-temperature cloth sensor, wherein the pre-heating and blowing component is used to soften the adhesive layer between the high-temperature cloth and the photovoltaic laminate with hot air at the lead-out hole on the surface of the photovoltaic laminate, and blow the high-temperature cloth at both ends of the adhesive layer to fit the bus bar; the pre-shoveling component is wedged between the high-temperature cloth and the surface of the photovoltaic laminate with the center of the lead-out hole as the reference, and gradually lifts up the high-temperature cloth and the bus bar from both ends, wherein the wedging angle gradually decreases with the change of the resistance, and under the corresponding auxiliary blowing of the pre-heating and blowing component, the high-temperature cloth and the bus bar are gradually lifted up by the pre-shoveling component to separate from the surface of the photovoltaic laminate, the high-temperature cloth fits the bus bar, and the length of the high-temperature cloth emerging from the end to the top of the bus bar is equal, the movable clamp clamps the two highly aligned emerging ends of the high-temperature cloth and tears the high-temperature cloth upward with the middle of the adhesive layer as the center of force;
[0035] The fixing seat and the high temperature cloth tearing unit form an integral structure, and the truss is provided with an integral structure corresponding to a plurality of high temperature cloths to be removed in parallel;
[0036] The high-temperature cloth recovery unit also includes an auxiliary seat corresponding to the overall structure on one side of the receiving conveyor belt close to the truss, and a brush assembly installed on each auxiliary seat, wherein the brush assembly corresponds to the movable clamping claws at the left and right ends, and the movable clamping claws are sent to the top of the receiving conveyor belt based on the forward movement of the truss, and the movable clamping claws release the high-temperature cloth, and the high-temperature cloth slides freely to the receiving conveyor belt and is sent into the recovery box; if the high-temperature cloth sensor obtains that the high-temperature cloth has not slipped off the movable clamping claw, the movable clamping claw is lowered and aligned with the height of the brush assembly, and the truss retreats and the brush assembly sweeps the high-temperature cloth entangled or stuck on the movable clamping claw toward the receiving conveyor belt, and the high-temperature cloth that has been brushed off is sent into the recovery box by the receiving conveyor belt;
[0037] The busbar shaping unit includes a positioning mechanism for driving the clamping and shaping modules to clamp the busbars and pull them up and down to calibrate the connection points with the photovoltaic laminate and to straighten the busbars.
[0038] Preferably, the lifting mechanism includes a lifting track extending up and down, a frame slidably arranged on the lifting track, and movable jaws, a pre-shoveling assembly, a preheating and purge assembly, and a high-temperature cloth sensor are all installed on the frame, wherein the pre-shoveling assembly and the preheating and purge assembly are correspondingly arranged on the rear and front sides of the frame, the movable jaws are correspondingly arranged on the left and right sides of the frame, and the high-temperature cloth sensor is located between the two movable jaws and can avoid the clamping or release of the movable jaws. It is explained here that the pre-shoveling, preheating and purge, and movable jaws can all move synchronously with the frame, and according to the reasonable position distribution, the various actions can be non-interfering with each other, and at the same time, they can better cooperate to avoid damage to the busbars or photovoltaic laminates caused by tearing off the high-temperature cloth.
[0039] According to a specific implementation and preferred aspect of the present invention, the pre-shoveling assembly includes a pre-shoveling seat slidably installed on a frame seat along the front-to-back direction, pre-shoveling claws installed on the left and right sides of the pre-shoveling seat by pivoting along the left-to-right direction, a pre-shoveling power device driving the pre-shoveling seat to move forward and backward, and a tension spring that drives the pre-shoveling claws to tilt and keeps the shovel tips of each pre-shoveling claw facing downward, wherein the shovel tips are subjected to the resistance of the high-temperature cloth and the bus bar, driving the tension spring to deform, and gradually reducing the wedging angle to gradually lift the high-temperature cloth and the bus bar upward until the bottom surface of the pre-shoveling claw is parallel to the surface of the photovoltaic laminate, and the bottom surface is located above the surface of the photovoltaic laminate to complete the pre-shoveling; when the pre-shoveling power device drives the pre-shoveling seat to move backward and reset, the pre-shoveling claws are separated from the high-temperature cloth, and the tension spring drives the pre-shoveling claws to reset.
[0040] Preferably, the top surface of the shovel tip of each pre-shovel clamp is an inclined surface that tilts from back to front and downward, the bottom surface of the shovel tip of the pre-shovel clamp is a plane, and a wedge-shaped block with a triangular cross-section is formed between the top surface and the bottom surface; in this way, the high-temperature cloth and the bus bar can be gradually lifted up as the shovel is gradually inserted, reducing the deformation rate of the bus bar, and at the same time further increasing the fit between the high-temperature cloth and the bus bar.
[0041] Furthermore, the pre-shovel power device is a power cylinder arranged along the front-rear direction, wherein the driving mode of the power lever is hydraulic, pneumatic or electric.
[0042] Furthermore, the pivot is rotatably connected to the pre-shoveling seat from the middle of the pre-shoveling clamping claw, there are two tension springs, and the two ends of each tension spring are correspondingly connected to the rear ends of the pre-shoveling seat and the pre-shoveling clamping claw on the same side.
[0043] According to another specific implementation and preferred aspect of the present invention, the preheating and blowing assembly includes a hot air duct installed on a frame and extending up and down, an air inlet joint arranged at the upper end of the hot air duct, an air outlet nozzle arranged at the lower end of the hot air duct, and a hot air supply component, wherein the hot air blown out from the air outlet nozzle can soften the adhesive layer between the high-temperature cloth and the surface of the photovoltaic laminate, and the blowing area formed by the hot air is changed synchronously with the shoveling of the pre-shovel to make the high-temperature cloth fit the busbar, and at the same time, the two ends of the high-temperature cloth are relatively kept at equal lengths to emerge from the ends of the busbar. Here, it should be noted that the core of the preheating and blowing assembly used in this application is: 1. Softening the adhesive layer; 2. Cooperating with the pre-shovel to make the high-temperature cloth fit the busbar relatively flatly, which is convenient for the alignment, clamping and tearing of the movable jaws, especially in the process of withdrawing the pre-shovel, the hot air blowing can also prevent the high-temperature cloth from moving synchronously with the pre-shovel.
[0044] Preferably, the air outlet nozzle is installed in the hot air duct in an upward and downward manner, and gradually approaches the surface of the photovoltaic laminate as the pre-shovel assembly is shoveled in to form a partial upward purge airflow. Here, by approaching the air outlet nozzle, the airflow can better form an upward airflow along the inclined surface of the shovel clamp to relatively fit the high-temperature cloth and the busbar, and also reduce the misalignment rate of the high-temperature cloth caused by the reset of the pre-shovel clamp.
[0045] According to another specific implementation and preferred aspect of the present invention, the movable clamp includes a left chuck module and a right chuck module installed on a frame seat for sliding adjustment along the left and right directions, wherein the left chuck module and the right chuck module are symmetrically arranged, wherein the left chuck module includes a left seat side plate, a lower shovel clamp and an upper clamp installed on the left seat side plate and capable of relative movement to form clamping, and a clamping power device for driving the lower shovel clamp and the upper clamp to move to clamp or release and reset.
[0046] Preferably, the lower shovel clamp is rotatably mounted on the left seat side plate via a rotating shaft extending along the front-to-back direction, the upper clamp is rotatably mounted on the lower shovel clamp via a rotating shaft extending along the front-to-back direction, the clamping power device is mounted on the lower shovel clamp and is used to drive the upper clamp to rotate around the rotating shaft to clamp or release; the left chuck module also includes an elastic member that keeps the lower shovel clamp intersecting with the surface of the photovoltaic laminate and keeps the entire left chuck module in a dynamic balance state, wherein the two ends of the elastic member are respectively connected to the lower shovel clamp and the left seat side plate.
[0047] In some specific embodiments, the elastic member is a tension spring, and positioning columns are respectively provided on the lower shovel clamp and the left seat side plate, and the two ends of the tension spring are respectively connected to the positioning columns; the tension spring has an initial state and a deformation state, wherein in the initial state, the tension spring is not deformed, and the left clamp module is in a dynamic balance state, and the lower shovel clamp remains tilted with the claw tip facing downward; when the lower shovel clamp and the upper clamp move relative to each other to form a clamp, the tension spring is stretched, and the claw tip of the lower shovel clamp moves downward and upward until the bottom surface of the lower shovel clamp is parallel to the surface of the photovoltaic laminate, and the fitted high-temperature cloth and bus bar are relatively separated from the two ends, and at the same time, driven by the lifting mechanism, the left clamp module and the right clamp module clamp the two ends of the high-temperature cloth and move upward so that the high-temperature cloth is separated from the surface of the photovoltaic laminate from the glue layer of the lead-out hole, and the two bus bars are pulled upward and close when the high-temperature cloth is pulled upward and torn off.
[0048] Furthermore, the shape of the lower shovel claw is the same as that of the pre-shovel claw, and a wedge-shaped block with a triangular cross section is formed between the top and bottom surfaces. The advantage of this design is that even if the high-temperature cloth accidentally falls back to the surface of the photovoltaic laminate, it can be gradually shoveled up and kept at the same height and angle to tear off the high-temperature cloth.
[0049] According to another specific implementation and preferred aspect of the present invention, tracks perpendicular to the truss are provided on opposite sides of the truss, racks consistent with the extension direction of the tracks are provided on the tracks, both ends of the truss cooperate with the tracks, and the ends of the truss are also provided with traveling gears matching the racks and traveling motors driving the traveling gears to rotate.
[0050] Preferably, there are two racks, which are symmetrically distributed on the left and right. The travel gear and the travel motor constitute a travel power component, which corresponds to the rack and is symmetrically arranged at both ends of the truss.
[0051] In addition, the material collection conveyor belt is an annular belt, the auxiliary seat can be disassembled and installed on the side of the annular belt, and the auxiliary seat includes a seat bottom plate, and seat side plates that are upward and inwardly inclined from both ends of the seat bottom plate, and the brush assembly is symmetrically installed on the seat side plates on the left and right sides.
[0052] Preferably, the brush assembly includes a bristle holder and bristles mounted on the bristle holder, wherein the bristle holder can be assembled and adjusted up and down along the extension direction of the seat side plate; the bristles are perpendicular to the seat side plate and are divided into multiple layers from top to bottom.
[0053] Furthermore, the clamping and shaping module includes a positioning module located in the middle, a left extrusion module and a right extrusion module located on the left and right sides and capable of relative movement and extrusion, and a front extrusion module and a rear extrusion module located on the front and back sides and capable of relative movement and extrusion, wherein the self-positioning module is inserted between the two bus bars, and the left extrusion module and the right extrusion module move to extrude and shape the two bus bars with the left and right sides of the positioning module as the reference, and the front extrusion module and the rear extrusion module move to extrude and shape the two bus bars with the front and back sides of the positioning module as the reference. Therefore, through multi-directional extrusion and shaping in front, back, left, and right directions, the two bus bars are kept relatively parallel and aligned.
[0054] In some specific embodiments, the alignment mechanism includes a pulling motion seat and a pulling power device that move in the up-down direction, wherein the clamping and shaping module is installed on the pulling motion seat. As for the pulling operation, generally one busbar is clamped and pulled up first, then another busbar is clamped and pulled up, and finally both busbars are clamped and pulled up at the same time. Of course, in general, the two busbars are pulled up relatively symmetrically, so it is most efficient to directly pull the two busbars synchronously.
[0055] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:
[0056] In the existing high-temperature cloth and busbar processing, the clamping claws are very likely to scratch the photovoltaic laminate and cause damage to the photovoltaic laminate during the process of scraping, clamping and then lifting the high-temperature cloth to be torn off, which reduces the yield of photovoltaic products. In addition, it is difficult to keep the clamping length formed by the clamping claws at both ends consistent. Therefore, in the process of clamping and pulling up, the bending point of the busbar is not the connection point with the photovoltaic module, resulting in the two busbars being uneven in height or the bending point forming a penetration obstacle, which affects the installation of the junction box. At the same time, because EVA glue is formed between the high-temperature cloth and the photovoltaic module, if it is pulled forcibly, it will not only damage the surface structure of the photovoltaic module, but also very likely cause the busbar to be deformed or broken by extreme pulling, increasing the difficulty of installation of the subsequent junction box process. Then, the The shaping formed is basically in the same dimension, and the relative extrusion shaping on the left and right, front and back cannot control the length of the busbar to be erected. Therefore, at least the shaping needs cannot be met in terms of the alignment of the erection height; finally, in the process of recovering the high-temperature cloth, once the high-temperature cloth is entangled or stuck in the clamp (or stuck to the clamp) due to damage, the high-temperature cloth cannot be separated from the clamp by the loose movement of the clamp. In this way, the unloaded high-temperature cloth remains on the clamp, which will directly affect the tearing operation of the next high-temperature cloth, and will further lead to the erection implementation of the busbar and other deficiencies. The present invention cleverly solves the various deficiencies of the existing structure through the overall design of the integrated processing process of tearing, recycling and erecting and shaping the photovoltaic high-temperature cloth.After adopting the integrated process of tearing off, recycling and erecting and shaping the busbar of the photovoltaic high-temperature cloth, first, the high-temperature cloth is blown by a hot air flow blowing from front to back, so that the high-temperature cloth is relatively attached to the busbar, and the bonding part is preheated and softened at the same time, and then a pre-shovel is used to wedge between the surface of the photovoltaic laminate and the high-temperature cloth from the left and right sides along the forward movement, and the wedging angle gradually decreases as the resistance changes, and the high-temperature cloth and the busbar on the left and right sides are both lifted up, and at the same time, the pre-shovel action is reset with the assistance of the preheated airflow, and the high-temperature cloth is attached to the return bar, and the high-temperature cloth is removed from the end The two ends of the high-temperature cloth are respectively exposed from the top of the bus bar, and the lengths of the exposed parts are equal, and the high-temperature cloth and the bus bar are symmetrically arranged about the gluing part; then, the shovel clamping claws that move relatively left and right are used to shovel into the bottom of the raised high-temperature cloth, and the exposed end is clamped by the relative movement of the shovel clamping claws, and the high-temperature cloth is peeled off upward with the gluing part as the center of force, and the bus bar is driven to stand up while the high-temperature cloth is torn off; then, the erected bus bar is relatively straightened and shaped in the left and right and front and back directions by the extrusion module that moves in the front-back and left-right directions based on the positioning grid, and then the bus bar is pulled out by pulling. The flow bar is pulled to calibrate the connection point with the photovoltaic laminate as the vertical end point; finally, the high-temperature cloth clamped by the shovel clamp is transferred to the material collection conveyor belt and the shovel clamp is released, and the high-temperature cloth slides freely to the material collection conveyor belt below and is sent to the recovery box. At the same time, the high-temperature cloth sensor verifies whether the high-temperature cloth is separated from the shovel clamp. When it is not separated from the shovel clamp, the position of the shovel clamp is adjusted to align with the fixed brush, and the shovel clamp is brushed by the brush, and the high-temperature cloth that is brushed and dropped is sent to the recovery box by the material collection conveyor belt. Therefore, on the one hand, the present invention is based on the implementation of preheating and pre-shoveling, which not only avoids the high-temperature cloth and the converging flow When the strips are scooped up, the surface of the photovoltaic laminate is damaged; and the middle of the adhesive layer is used as the center of force to tear the strips while maintaining tension and pulling upward at the ends, so as to avoid uneven heights or large deformation differences between the two bus bars after the high-temperature cloth is torn off. At the same time, multi-dimensional extrusion and pulling are combined to straighten and align the bus bars; on the other hand, based on the setting of the brush assembly and in conjunction with the induction of the high-temperature cloth sensor, the high-temperature cloth entangled or stuck on the movable clamp is brushed toward the receiving conveyor belt and collected by the recycling box to avoid the high-temperature cloth being unable to detach from the movable clamp and affecting the tearing off of the next piece of high-temperature cloth.

[0074] like Figures 1 to 10 As shown, the integrated processing process for tearing off, recycling and erecting and shaping the photovoltaic high-temperature cloth B of this embodiment, the integrated processing equipment for tearing off, recycling and erecting and shaping the photovoltaic high-temperature cloth B adopted includes a frame J, a truss 1 capable of moving horizontally along the front and rear directions, a fixed seat 2 installed on the truss 1, a high-temperature cloth tearing unit 3, a high-temperature cloth shaping unit 4, and a high-temperature cloth recovery unit 5.
[0075] In this example, the rack J is provided with an entrance and an exit in the left and right directions for the horizontal entry and exit of photovoltaic modules, and a ring conveyor belt is provided at the entrance and exit to transfer photovoltaic modules, wherein the surface of the photovoltaic modules entering the working area is provided with three groups of evenly spaced high-temperature cloths B and bus bars H, each group of high-temperature cloths B and bus bars H is composed of a piece of high-temperature cloth B and two bus bars H, and when entering the working area, the surface of the photovoltaic modules is horizontally arranged, the high-temperature cloth B extends horizontally, and the two bus bars H pass through the high-temperature cloth B and are bent to the left and right respectively and pressed on the left and right ends of the high-temperature cloth B. Therefore, the processing all-in-one machine of the present application is to tear off the high-temperature cloth B, erect the bus bar H upwards, and recycle the high-temperature cloth B based on integration, and is implemented automatically.
[0076] In some specific embodiments, rails 6 perpendicular to the truss 1 are provided on opposite sides of the truss 1, racks 7 in the same extension direction as the rails 6 are provided on the rails 6, both ends of the truss 1 are matched with the rails 6, and the ends of the truss 1 are also provided with travel gears 8 matched with the racks 7 and travel motors 9 driving the travel gears 8 to rotate. In this example, there are two racks 7, which are symmetrically distributed on the left and right. The travel gears 8 and the travel motors 9 constitute the travel power parts, which correspond to the racks 7 and are symmetrically arranged at both ends of the truss 1. In short, the travel gears 8 and the racks 7 form a match, and move laterally along the length direction of the racks 7 during the synchronous rotation of the two travel gears 8.
[0077] The fixing base 2 and the high temperature cloth tearing unit 3 form an integral structure. Figure 1 There are three overall structures, and they are arranged side by side in the length direction of the truss 1. At the same time, the three overall structures are indirectly adjusted with the spacing distance of the three high-temperature cloths B to be removed side by side on the same photovoltaic module. Therefore, the three high-temperature cloths B on the same photovoltaic module are in synchronous tearing, the bus bar H is in synchronous shaping, and the high-temperature cloth B is in synchronous recycling mode to complete the surface treatment of the photovoltaic module.
[0078] The high-temperature cloth tearing unit 3 includes movable jaws 30 located at both ends, a lifting mechanism 31 that drives the movable jaws 30 to move up and down, a pre-shoveling assembly 32 that is arranged on the rear side of the movable jaws 30 and can move forward to scoop up the high-temperature cloth B and the bus bar H, a preheating and blowing assembly 33 that is located on the front side and can form hot air blowing, and a high-temperature cloth sensor 34.
[0079] In some specific embodiments, the lifting mechanism 31 includes a lifting track 310 extending up and down, a frame 311 slidably disposed on the lifting track 310, and the movable clamp 30 is installed on the frame 311. Under the guidance of the lifting track 310, the high-temperature cloth B can be torn off more smoothly.
[0080] The movable clamping jaw 30 includes a left clamping head module 301 and a right clamping head module 302 which are mounted on the frame 311 and are slidably adjusted along the left and right directions, wherein the left clamping head module 301 and the right clamping head module 302 are symmetrically arranged. The left clamping head module 301 and the right clamping head module 302 are symmetrically and synchronously moved, thereby ensuring that the force center is located in the middle of the lead-out hole, thereby achieving the goal of tearing the high-temperature cloth B while relatively balancing the upward pulling force on the two bus bars H. In this example, the left chuck module 301 is explained in detail. According to the principle of symmetry, the structure of the right chuck module 302 is also clear. Specifically, the left chuck module 301 includes a left seat side plate a, a lower shovel clamp b and an upper clamp c installed on the left seat side plate a and capable of relative movement to form a clamp, a clamping power device d that drives the lower shovel clamp b and the upper clamp c to move to clamp or release and reset, and an elastic member e that keeps the lower shovel clamp b intersecting with the surface of the photovoltaic laminate and keeps the entire left chuck module 301 in a dynamic balance state (in short, the right chuck module 302 includes a right seat side plate a′, a lower shovel clamp b′, an upper clamp c′, a clamping power device d′, and an elastic member e′). Furthermore, the lower shovel clamp b is rotatably mounted on the left seat side plate a via a rotating shaft extending along the front-to-back direction, the upper clamp c is rotatably mounted on the lower shovel clamp b via a rotating shaft extending along the front-to-back direction, the clamping power device d is mounted on the lower shovel clamp b, and is used to drive the upper clamp c to rotate around the rotating shaft to clamp or release, and the two ends of the elastic member e are respectively connected to the lower shovel clamp b and the left seat side plate a. In some specific embodiments, the elastic member e is a tension spring, and positioning columns m are respectively provided on the lower shovel clamping jaw b and the left seat side plate a, and the two ends of the tension spring are respectively connected to the positioning columns m, wherein the tension spring has an initial state and a deformation state, wherein in the initial state, the tension spring is not deformed, and the left clamping head module 301 is in a dynamic balance state, and the lower shovel clamping jaw b is kept tilted with the claw tip facing downward; when the lower shovel clamping jaw b and the upper clamping jaw c move relative to each other to form a clamp, the tension spring is stretched, and the claw tip of the lower shovel clamping jaw b moves downward and upward until the bottom surface of the lower shovel clamping jaw b is parallel to the surface of the photovoltaic laminate, and the bonded high-temperature cloth B and the bus bar H are relatively separated from the two ends. At the same time, driven by the lifting mechanism 31, the left clamping head module 301 and the right clamping head module 302 clamp the two ends of the high-temperature cloth B and move upward so that the high-temperature cloth B is separated from the surface of the photovoltaic laminate from the glue layer of the lead-out hole, and when the high-temperature cloth B is pulled upward and torn off, the two bus bars H are pulled upward and close. At the same time, the top surface of the lower shoveling jaw b of the left clamping head module 301 is inclined from left to right and from top to bottom, and the bottom surface is a plane, so a wedge-shaped block with a triangular cross section is formed between the top surface and the bottom surface. The advantage of this design is that even if the high-temperature cloth B accidentally falls back to the surface of the photovoltaic laminate, it can be gradually shoveled up to maintain the same height and angle to implement the tearing of the high-temperature cloth B. As for the clamping power device d, it is a conventional power cylinder (electric, pneumatic or hydraulic).
[0081] In some specific embodiments, the pre-shoveling assembly 32 includes a pre-shoveling seat 320 slidably mounted on the frame 311 along the front-back direction, a pre-shoveling clamp 321 coaxially mounted on opposite sides of the pre-shoveling seat 320, a pre-shoveling power device 322 driving the pre-shoveling seat 320 to move forward and backward, and a tension spring 323 driving the pre-shoveling clamp 321 to tilt and keep the shovel tip of each pre-shoveling clamp 321 facing downward, wherein the pre-shoveling clamp 321 is kept intersecting with the surface of the photovoltaic laminate for pre-shoveling, and the shovel tip is rotated upward by resistance to reduce the tilt angle of the pre-shoveling clamp 321, until the bottom surface of the pre-shoveling clamp 321 is parallel to the surface of the photovoltaic laminate, and the bottom surface is located on the surface of the photovoltaic laminate to complete the pre-shoveling. In this example, the top surface of the pre-shoveling clamp 321 is an inclined surface that tilts from back to front and tilts downward, the bottom surface of the pre-shoveling clamp 321 is a plane, and a wedge block with a triangular cross section is formed between the top surface and the bottom surface. In this way, the high-temperature cloth B and the bus bar H can be gradually lifted up as the shovel is gradually inserted, reducing the deformation rate of the bus bar H, and further increasing the fit between the high-temperature cloth B and the bus bar H. At the same time, the two pre-shovel claws 321 are rotatably connected to the pre-shovel seat 320 from the middle by a pivot s extending in the left-right direction. There are two tension springs 323, and the two ends of each tension spring 323 are correspondingly connected to the rear ends of the pre-shovel seat 320 and the pre-shovel claws 321 on the same side. Here, by adaptively adjusting the state of the pre-shovel based on the change in resistance, not only the probability of deformation (such as bending) of the bus bar H is reduced, but also the high-temperature cloth B and the bus bar H can be gradually propped up, and at the same time, they can be reset synchronously to prepare for the next pre-shovel. The pre-shovel power device 322 is a power cylinder arranged in the front-to-back direction, in which the power of the power cylinder is pneumatic, hydraulic or electric.
[0082] In some specific embodiments, the preheating and purge assembly 33 includes a hot air pipeline 330 installed on the frame 311 and extending up and down, an air inlet joint 331 arranged at the upper end of the hot air pipeline 330, an air outlet nozzle 332 arranged at the lower end of the hot air pipeline 330, and a hot air supply component, wherein the air outlet nozzle 332 is located at the front side of the high-temperature cloth B, and the air flow formed is blown from front to back between the high-temperature cloth B and the surface of the photovoltaic laminate so that the high-temperature cloth B fits the bus bar H and softens the glue layer between the high-temperature cloth B and the surface of the photovoltaic laminate. In short, the blown air flow completely covers the entire area where the high-temperature cloth B is located. At the same time, the air outlet nozzle 332 gradually approaches the surface of the photovoltaic laminate as the pre-shoveling assembly 32 is shoveled in to form a partial upward purge airflow. Here, without changing the direction of the airflow, the airflow area is changed by the height change to achieve the purpose of airflow blowing the high-temperature cloth B to fit the busbar H neatly (in other words, the airflow blows the high-temperature cloth B relatively flat so that the height and length of the clamping are aligned, avoiding the situation where the two busbars H are subjected to different forces and increasing the difficulty of later shaping). This is very important because preheating and pre-shoveling are related. The advantage of doing so is to avoid the relative separation of the high-temperature cloth B and the busbar H, and to enable both to be in a flat state and to be lifted from both ends. At the same time, the two are relatively fitted, which is more conducive to later clamping. In order to implement the linkage between the two, the heat purge component 33 is movably installed on the bracket 311 up and down, and as the pre-shoveling component 32 is gradually shoveled in, the heat purge component 33 gradually approaches the surface of the photovoltaic laminate. A more reasonable and bottom-cutting airflow is used to increase the flatness and fit of the high-temperature cloth B (relative to the busbar H).
[0083] In some specific embodiments, the high temperature cloth sensor 34 obtains the information of the high temperature cloth B between the left clamping head module 301 and the right clamping head module 302 to verify the tearing of the high temperature cloth B. Specifically, the high temperature cloth sensor 34 is located between the left clamping head module 301 and the right clamping head module 302 and can avoid the upper clamping jaw c. In short, through the high temperature cloth sensor 34 (generally a photoelectric sensor), once the high temperature cloth B is not successfully torn off, an alarm operation can be performed to ensure that the phenomenon of missing the removal of the high temperature cloth B will not occur.
[0084] In this example, the high-temperature cloth tearing unit 3 and the busbar shaping unit 4 are located on the same fixed seat 2 and are arranged in a front-to-back layout. In this example, the busbar shaping unit 4 includes a clamping and shaping module 40 and a positioning mechanism 41 that drives the clamping and shaping module 40 to clamp the busbar H in the up and down directions to calibrate the connection point position with the photovoltaic laminate and straighten the busbar H.
[0085] In this example, the clamping and shaping module 40 includes a positioning module 400 located in the middle, a left extrusion module 401 and a right extrusion module 402 located on the left and right sides and capable of relative movement and extrusion, and a front extrusion module 403 and a rear extrusion module 404 located on the front and back sides and capable of relative movement and extrusion, wherein the self-positioning module 400 is inserted between the two bus bars H, and the left extrusion module 401 and the right extrusion module 402 move to extrude and shape the two bus bars H with the left and right sides of the positioning module 400 as the reference, and the front extrusion module 403 and the rear extrusion module 404 move to extrude and shape the two bus bars H with the front and back sides of the positioning module 400 as the reference. Therefore, through multi-directional extrusion shaping in front, back, left and right directions, the two bus bars H are kept relatively parallel and aligned. The calibration mechanism 41 includes a pulling motion seat 410 that moves in the up and down direction, and a pulling power device 411, wherein the clamping and shaping module 40 is installed on the pulling motion seat 410. As for the pulling operation, generally, one bus bar H is first clamped and pulled up, then the other bus bar H is clamped and pulled up, and finally both bus bars H are clamped and pulled up at the same time. Of course, in general, the two bus bars H are pulled up relatively symmetrically, so it is most efficient to directly pull the two bus bars H synchronously.
[0086] In some specific embodiments, the high-temperature cloth recovery unit 5 also includes an auxiliary seat 52 corresponding to the overall structure on one side of the receiving conveyor belt 50 close to the truss 1, and a brush assembly 53 installed on each auxiliary seat 52, wherein the brush assembly 53 corresponds to the movable jaws 30 at the left and right ends, and the movable jaws 30 are sent to the top of the receiving conveyor belt 50 based on the forward movement of the truss 1, and the movable jaws 30 release the high-temperature cloth B, and the high-temperature cloth B slides freely to the receiving conveyor belt 50 and is sent to the recovery box 51; if the high-temperature cloth sensor 34 obtains that the high-temperature cloth B has not slipped from the movable jaws 30, the movable jaws 30 descend and are highly aligned with the brush assembly 53, and when the truss 1 retreats, the brush assembly 53 will brush the high-temperature cloth B entangled or stuck on the movable jaws 30 toward the receiving conveyor belt 50, and the high-temperature cloth B that has been brushed off is sent to the recovery box 51 by the receiving conveyor belt 50.
[0087] In some specific embodiments, the receiving conveyor belt 50 is an annular belt, the auxiliary seat 52 can be detachably mounted on the side of the annular belt, and the auxiliary seat 52 includes a seat bottom plate 520, seat side plates 521 that are upward and inwardly inclined from both ends of the seat bottom plate 520, and the brush assembly 53 is symmetrically mounted on the seat side plates 521 on the left and right sides, and the brush assembly 53 includes a bristle seat 530 and bristles 531 mounted on the bristle seat 530, wherein the bristle seat 530 can be adjusted and assembled up and down along the extension direction of the seat side plates 521; the bristles 531 are perpendicular to the seat side plates 521 and are divided into multiple layers from top to bottom. Here, not only the needs of brushing at different angles and heights are met, but also the structure formed has strong impact resistance and long service life.
[0088] In summary, the implementation process of this embodiment is as follows:
[0089] S1. Removal of high temperature cloth;
[0090] First, the high-temperature cloth is purged by a hot air flow blowing from front to back, so that the high-temperature cloth is relatively attached to the bus bar, and the bonding part is preheated and softened at the same time, wherein the preheating area is changed synchronously with the shoveling of the pre-shovel so that the purging airflow can attach the high-temperature cloth to the bus bar; at the same time, the pre-shovel is used to wedge between the surface of the photovoltaic laminate and the high-temperature cloth from the left and right sides along the forward movement, and the wedging angle gradually decreases as the resistance changes, and the high-temperature cloth and the bus bar on the left and right sides are both lifted up, and at the same time, the pre-shovel action is reset with the assistance of the preheating airflow, the high-temperature cloth is attached to the return bar, and the high-temperature cloth emerges from the top of the bus bar from the ends respectively, wherein the emerging lengths are equal, and the high-temperature cloth and the bus bar are symmetrically arranged about the bonding part, and at the same time, as the pre-shovel is gradually shoveled in, the preheating airflow outlet gradually approaches the surface of the photovoltaic laminate; as the pre-shovel is reset, the preheating is reset synchronously;
[0091] Next, the left and right shovel claws are used to shovel into the bottom of the raised high-temperature cloth, and the protruding end is clamped by the relative movement of the shovel claws, wherein the clamping height formed by the left and right shovel claws is the same, and the high-temperature cloth is clamped at the left and right ends and maintained in a relatively flattened mode, and then moves upward to gradually tear off the photovoltaic laminate, and then the high-temperature cloth is clamped at the left and right ends and the high-temperature cloth is clamped downward and outward by the relative clamping of the shovel claws. After completing the left and right clamping, the gluing point is used as the force center, and the force of tearing upward along the clamping direction is maintained to remove the high-temperature cloth and drive the busbar upward to stand up while the high-temperature cloth is torn off. When the high-temperature cloth is separated from the photovoltaic laminate, the shovel claws clamp the two ends of the high-temperature cloth and rotate inward, and the high-temperature cloth is relatively folded downward to form a V-shape or U-shape;
[0092] S2, busbar erection and shaping
[0093] First, shift forward so that the clamping and shaping module corresponds to the position of the two bus bars, that is, insert the self-positioning module between the two bus bars, and the left extrusion module and the right extrusion module move to extrude and shape the two bus bars with the left and right sides of the positioning module as the reference, and the front extrusion module and the rear extrusion module move to extrude and shape the two bus bars with the front and rear sides of the positioning module as the reference; then, perform the pulling operation, that is, first clamp one bus bar and pull it up, then clamp another bus bar and pull it up, and finally clamp both bus bars and pull them up at the same time (optional), and pull the bus bars to calibrate the connection point with the photovoltaic laminate as the erection end point;
[0094] S3. Recycling of high temperature cloth
[0095] The high-temperature cloth clamped by the shovel clamp is transferred to the material receiving conveyor belt 50 and the shovel clamp is released. The high-temperature cloth slides freely to the material receiving conveyor belt 50 below and is sent to the recovery box 51. At the same time, the high-temperature cloth sensor verifies whether the high-temperature cloth is separated from the shovel clamp. When it is not separated from the shovel clamp, the position of the shovel clamp is adjusted to align with the fixed brush, and the shovel clamp is brushed by the brush. The high-temperature cloth that has been brushed off is sent to the recovery box 51 by the material receiving conveyor belt 50.
[0096] In summary, after adopting the integrated process of tearing off, recycling and erecting and shaping the busbar of the photovoltaic high-temperature cloth, first, the high-temperature cloth is blown by a hot air flow blowing from front to back, so that the high-temperature cloth is relatively fitted to the busbar, and the bonding part is preheated and softened at the same time, and then or synchronously a pre-shovel is used to wedge between the surface of the photovoltaic laminate and the high-temperature cloth from the left and right sides along the forward movement, and the wedging angle gradually decreases with the change of resistance, and the high-temperature cloth and the busbar on the left and right sides are both lifted up, and at the same time, the pre-shovel action is reset with the assistance of the preheated airflow, the high-temperature cloth is fitted with the return bar, and the high-temperature cloth emerges from the top of the busbar from the ends, wherein the emerging lengths are equal, and the The high-temperature cloth and the busbar are arranged symmetrically about the gluing part; then, the shovel clamping claws that move left and right are used to shovel into the bottom of the raised high-temperature cloth, and the protruding end is clamped by the relative movement of the shovel clamping claws, and the high-temperature cloth is peeled and torn upward with the gluing part as the center of force, and the busbar is driven upward to stand upright while the high-temperature cloth is torn off; then, the erected busbar is relatively straightened and shaped in the left and right and front and back directions by an extrusion module that moves in the front-back and left-right directions based on the positioning grid, and then the busbar is pulled by pulling to calibrate the connection point with the photovoltaic laminate as the erection end point; finally, the high-temperature cloth clamped by the shovel clamping claw is transferred to the material receiving conveyor belt and the shovel clamp is released The high-temperature cloth slides freely to the receiving conveyor belt below and is sent to the recycling box. At the same time, the high-temperature cloth sensor verifies whether the high-temperature cloth is separated from the shovel clamping claw. When it is not separated from the shovel clamping claw, the shovel clamping claw is adjusted to align with the fixed brush, and the shovel clamping claw is brushed by the brush, and the high-temperature cloth that is brushed and dropped is sent to the recycling box by the receiving conveyor belt. Therefore, on the one hand, the present invention is based on the implementation of preheating and pre-shoveling, which not only avoids damage to the surface of the photovoltaic laminate when the high-temperature cloth and the bus bar are shoveled up; and under the action of maintaining tension and pulling up at the end, tearing is carried out with the middle part of the adhesive layer as the force center, so as to avoid the situation that the two bus bars are uneven in height or have a large difference in deformation after the high-temperature cloth is torn off. At the same time, the busbars are straightened and aligned by combining multi-dimensional extrusion and pulling; on the other hand, based on the setting of the brush assembly and in conjunction with the induction of the high-temperature cloth sensor, the high-temperature cloth entangled or stuck on the movable clamp is brushed toward the material receiving conveyor belt and collected by the recycling material box to avoid the high-temperature cloth being unable to detach from the movable clamp and affecting the tearing of the next piece of high-temperature cloth; on the third aspect, based on the setting of the truss and the lifting, the movement in the front-to-back and up-and-down directions can be met, wherein under the guidance of the lifting track, the tearing of the high-temperature cloth is implemented more smoothly, and the high-temperature cloth tearing unit and the busbar shaping unit arranged in the front and back are interchanged in the horizontal direction of the truss to achieve the purpose of tearing off the high-temperature cloth first and then shaping the busbar;Fourthly, the structural design of the pre-shovel can gradually lift up the high-temperature cloth and the busbar as the shovel is gradually inserted, thereby reducing the deformation rate of the busbar and further increasing the fit between the high-temperature cloth and the busbar. At the same time, the pre-shovel that adaptively adjusts the state based on the resistance change not only reduces the probability of deformation (such as bending) of the busbar, but also can gradually prop up the high-temperature cloth and the busbar, and can also be synchronously reset to prepare for the next pre-shovel. Fifthly, the design of the preheating and purge assembly forms an airflow that blows from front to back between the high-temperature cloth and the surface of the photovoltaic laminate to make the high The warm cloth fits the busbar and softens the adhesive layer between the high-temperature cloth and the surface of the photovoltaic laminate. At the same time, the air outlet gradually approaches the surface of the photovoltaic laminate as the pre-shovel component gradually shovels into the hot purge component. Without changing the airflow direction, the airflow area is changed by height change. In conjunction with the pre-shovel, the high-temperature cloth is relatively flatly fitted to the busbar, so as to facilitate the alignment, clamping and tearing of the movable clamps. Especially in the process of withdrawing the pre-shovel, the hot air purge can also prevent the high-temperature cloth from moving synchronously with the pre-shovel, so as to achieve the purpose of the airflow blowing the high-temperature cloth to neatly fit the busbar (in other words, the airflow is used to The high-temperature cloth is relatively flattened so that the height and length of the clamping are aligned, avoiding the situation where the two bus bars are subjected to different forces and increasing the difficulty of later shaping), that is, a more reasonable and bottom-picking airflow is used to increase the flatness and fit of the high-temperature cloth (relative to the bus bar); the sixth aspect is to use symmetrical and synchronously moving left and right clamping modules to ensure that the force center is located in the middle of the lead-out hole, thereby achieving a relatively balanced upward pulling force on the two bus bars while tearing the high-temperature cloth; the seventh aspect is the coordination of the rack and the travel gear, combined with the slide rail to achieve multiple The high-temperature cloth is torn off synchronously through the whole structure, and the high-temperature cloth is unloaded simultaneously based on the movement of the truss; the eighth aspect is based on the setting of layered bristles, which not only meets the brushing needs of angle and height, but also has a strong impact resistance and long service life; the busbar shaping unit used in the ninth aspect ensures that the busbars are erected upward from the connection point of the photovoltaic laminate by moving forward and performing the clamping shaping of the clamping shaping module and the synchronous and / or sequential pulling shaping of the height, and the height of the busbars is aligned and more straight, which is convenient for the installation of the junction box in the later stage. ;
