Description

Technical Field

[0001] The invention belongs to the field of photovoltaics, and in particular relates to a photovoltaic high-temperature cloth removal and recycling system. 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 from the top of 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 the high-temperature cloth from both ends, 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. Although it can be implemented, it has the following technical defects:

[0004] 1) Since the high temperature cloth is relatively close to the surface of the photovoltaic laminate, the clamping claws are very likely to scratch the photovoltaic laminate during the clamping process, causing damage to the photovoltaic laminate, which reduces the yield of photovoltaic products;

[0005] 2) Since it is difficult to keep the clamping length of the clamping claws at both ends consistent, the bending point of the busbar during the clamping and pulling process 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;

[0006] 3) Since EVA glue is formed between the high temperature cloth and the surface of the photovoltaic laminate at the lead-out hole, forcible pulling will not only destroy the structure at the lead-out hole, but also cause transitional deformation of the busbar;

[0007] 4) During the tearing process of the high-temperature cloth, the high-temperature cloth is closer to the clamping jaws, and some of the high-temperature cloth is even entangled in the clamping jaws due to damage. Therefore, even if the clamping jaws are loosened, it is difficult to smoothly separate the high-temperature cloth from the clamping jaws. Once the separation is impossible, it will affect the tearing of the next high-temperature cloth. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved photovoltaic high temperature cloth removal and recycling system.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A photovoltaic high-temperature cloth removal and recycling system comprises a truss capable of moving laterally in a front-to-rear direction, a fixing seat mounted on the truss, a high-temperature cloth tearing unit, and a high-temperature cloth recycling unit, wherein the high-temperature cloth tearing unit comprises movable clamps at left and right ends, and a lifting mechanism driving the movable clamps to move up and down; the high-temperature cloth recycling unit comprises a receiving conveyor belt in the same length direction as the truss, and a recycling material box at the discharge end of the receiving conveyor belt.

[0011] In particular, the high-temperature cloth tearing unit also includes a pre-shoveling assembly arranged at the rear side of the movable clamping jaws and capable of moving forward to shovel the high-temperature cloth and the bus bar, a pre-heating and blowing assembly located at the front side and capable of forming hot air blowing, and a high-temperature cloth sensor, wherein the pre-heating and blowing assembly is used to blow hot air to the lead-out hole on the surface of the photovoltaic laminate to soften the adhesive layer between the high-temperature cloth and the photovoltaic laminate, and blow the high-temperature cloth at both ends of the adhesive layer to fit the bus bar; the pre-shoveling assembly 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 assembly, the high-temperature cloth and the bus bar are gradually lifted up by the pre-shoveling assembly 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 clamping jaws clamp the two highly aligned emerging ends of the high-temperature cloth and form a force center to tear the high-temperature cloth upward;

[0012] 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;

[0013] The high-temperature cloth recovery unit also includes an auxiliary seat located on the side of the receiving conveyor belt close to the truss and corresponding to the overall structure, and a brush assembly installed on each auxiliary seat, wherein the brush assembly corresponds to the movable jaws at the left and right ends, and the movable jaws are sent to the top of the receiving conveyor belt based on the forward movement of the truss, and the movable jaws 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 from the movable jaws, the movable jaws descend and are highly aligned with the brush assembly, and when the truss retreats, the brush assembly will brush the high-temperature cloth entangled or stuck on the movable jaws 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.

[0014] 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. Here, it is explained 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 busbar or photovoltaic laminate caused by tearing off the high-temperature cloth.

[0015] 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.

[0016] Preferably, the top surface of the shovel tip of each pre-shovel claw is an inclined surface that tilts from back to front and downward, the bottom surface of the shovel tip of the pre-shovel claw 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.

[0017] Furthermore, the pre-shovel power device is a power cylinder arranged along the front-to-back direction, wherein the driving mode of the power lever is hydraulic, pneumatic or electric.

[0018] Furthermore, the pivot is rotatably connected to the pre-shoveling seat from the middle of the pre-shoveling 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 claw located on the same side.

[0019] 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 relatively flat and fit the busbar, so as to facilitate 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.

[0020] 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 sweeping airflow. Here, by approaching the air outlet nozzle, the airflow can better form an upward airflow along the inclined surface of the shovel claw 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 claw.

[0021] According to another specific implementation and preferred aspect of the present invention, the movable clamping jaw 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 claw and an upper clamping jaw 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 claw and the upper clamping jaw to move to clamp or release and reset.

[0022] Preferably, the lower shovel claw is rotatably mounted on the left seat side plate via a rotating shaft extending along the front-to-back direction, the upper clamping jaw is rotatably mounted on the lower shovel claw via a rotating shaft extending along the front-to-back direction, the clamping power device is mounted on the lower shovel claw and is used to drive the upper clamping jaw to rotate around the rotating shaft to clamp or release; the left chuck module also includes an elastic member that keeps the lower shovel claw 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 claw and the left seat side plate.

[0023] In some specific embodiments, the elastic member is a tension spring, and positioning columns are respectively provided on the lower shovel claw 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 clamping module is in a dynamic balance state, and the lower shovel claw remains tilted with the claw tip facing downward; when the lower shovel claw and the upper clamping jaw move relative to each other to form a clamp, the tension spring is stretched, and the claw tip of the lower shovel claw moves downward and upward until the bottom surface of the lower shovel claw 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 clamping module and the right clamping 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.

[0024] 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 to maintain the same height and angle to implement the tearing of the high-temperature cloth.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0030] The existing high temperature cloth is generally torn off and recycled by using a clamping jaw to shovel in and clamp from both ends of the high temperature cloth, and then the clamping jaw moves upward to tear off the high temperature cloth, and the torn high temperature cloth needs to be transferred to the recycling material belt, and then the clamping jaw is released, and the high temperature cloth falls into the recycling material belt below for recycling. However, during the tearing of the high temperature cloth, the clamping jaw is very easy to scratch the photovoltaic laminate and cause damage to the photovoltaic laminate, which reduces the yield of photovoltaic products, and it is difficult to keep the clamping length formed by the clamping jaws at both ends consistent, that is, during the clamping and pulling process, the bending point of the bus bar is not the connection point with the photovoltaic module, resulting in the two bus bars being uneven in height or the bending point forming a penetration obstacle, which affects the installation of the junction box. At the same time, if the EVA adhesive layer is forcibly pulled, it will not only destroy the structure at the lead-out hole, but also cause the bus bar to transitionally deform. In addition, once the high temperature cloth is entangled on the clamping jaw due to damage, even if the clamping jaw is released, it is difficult to smoothly separate the high temperature cloth from the clamping jaw, etc. The present invention cleverly solves various deficiencies of the existing structure through the overall design of the photovoltaic high temperature cloth removal and recycling system. After adopting the photovoltaic high-temperature cloth removal and recycling system, the high-temperature cloth and the bus bar are preheated and pre-shoveled successively or simultaneously, wherein the preheating is to blow the high-temperature cloth through the hot air flow to relatively separate the high-temperature cloth and the surface of the photovoltaic laminate, and the hot air can also soften the glue layer at the lead-out hole, and the pre-shovel is to pre-shovel from both ends and from back to front to gradually lift the high-temperature cloth and the bus bar upward from both ends; then use the movable clamp to clamp the emerging end at a height aligned with the lead-out hole as the center of force to lift the high-temperature cloth; finally, based on the forward movement of the truss, the movable clamp and the high-temperature cloth are sent to the top of the receiving conveyor belt, the movable clamp releases the high-temperature cloth, the high-temperature cloth slides freely to the receiving conveyor belt and is sent to the recycling box, and at the same time, if the high-temperature cloth sensor obtains that the high-temperature cloth has not slipped from the movable clamp, the movable clamp descends and is aligned with the height of the brush assembly Alignment, when the truss retreats, the brush assembly will brush the high-temperature cloth wrapped or stuck on the movable clamping claw towards the material collection conveyor belt, and the high-temperature cloth that has been brushed off will be sent to the recovery box by the material collection conveyor belt. Therefore, on the one hand, based on the implementation of preheating and pre-shoveling, the present invention not only avoids damage to the surface of the photovoltaic laminate when the high-temperature cloth and the bus bar are shoveled up; but also facilitates the movable clamping claw to clamp the two highly aligned protruding ends of the high-temperature cloth and form a tearing with the middle of the glue layer as the force center, so as to avoid the situation where the two bus bars are uneven in height or have a large difference in deformation after the high-temperature cloth is torn off; 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 wrapped or stuck on the movable clamping claw will be brushed towards the material collection conveyor belt and collected by the recovery box, so as to avoid the high-temperature cloth being unable to detach from the movable clamping claw and affecting the tearing of the next piece of high-temperature cloth.

[0047] like Figures 1 to 8 As shown, the photovoltaic high-temperature cloth dismantling and recycling system of this embodiment includes a truss 1 that can move laterally along the front-to-back direction, a fixing seat 2 installed on the truss 1, a high-temperature cloth tearing unit 3, and a high-temperature cloth recycling unit 4, wherein the high-temperature cloth recycling unit 4 includes a material receiving conveyor belt 40 that is consistent with the length direction of the truss 1, and a recycling material box 41 located at the discharge end of the material receiving conveyor belt 40.

[0048] See again Figure 2 The high-temperature cloth B is horizontally arranged on the surface of the photovoltaic laminate, and two bus bars H are relatively flatly pressed on the high-temperature cloth B, one facing left and the other facing right. At the same time, the core of this application is to remove the high-temperature cloth B, move the high-temperature cloth B and unload it to the receiving conveyor belt 40, and finally collect the high-temperature cloth B by the recycling box 41.

[0049] In some specific embodiments, rails 5 perpendicular to the truss 1 are provided on opposite sides of the truss 1, racks 6 in the same direction as the extension of the rails 5 are provided on the rails 5, both ends of the truss 1 are matched with the rails 5, and the ends of the truss 1 are also provided with travel gears 7 matched with the racks 6 and travel motors 8 driving the travel gears 7 to rotate. In this example, there are two racks 6, which are symmetrically distributed on the left and right. The travel gears 7 and the travel motors 8 constitute travel power parts, which correspond to the racks 6 and are symmetrically arranged at both ends of the truss 1. In short, the travel gears 7 and the racks 6 form a match, and move laterally along the length direction of the racks 6 during the synchronous rotation of the two travel gears 7.

[0050] The fixing base 2 and the high temperature cloth tearing unit 3 form an integral structure. Figure 1 There are three overall structures, which are arranged side by side in the length direction of the truss 1. At the same time, the spacing between the three overall structures is adaptively adjusted with the spacing distance of three high-temperature cloths to be removed side by side on the same photovoltaic module.

[0051] 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.

[0052] 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 mounted on the frame 311. Under the guidance of the lifting track, the high temperature cloth can be torn off more smoothly.

[0053] The movable clamping jaw 30 includes a left clamping head module 301 and a right clamping head module 302 which are mounted on a bracket 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 and the right clamping head module which move symmetrically and synchronously are adopted to ensure that the force center is located in the middle of the lead-out hole, thereby achieving the goal of tearing the high-temperature cloth while applying a relatively balanced upward pulling force to the two bus bars. 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 claw b and an upper clamping claw 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 claw b and the upper clamping claw c to move to clamp or release and reset, and an elastic member e that keeps the lower shovel claw b intersecting with the surface of the photovoltaic laminate and keeps the entire left chuck module in a dynamic balance state (in short, the right chuck module 302 includes a right seat side plate a′, a lower shovel claw b, an upper clamping claw c, a clamping power device d, and an elastic member e). Furthermore, the lower shovel claw b is rotatably mounted on the left seat side plate a via a rotating shaft extending along the front-to-back direction, the upper clamping claw c is rotatably mounted on the lower shovel claw b via a rotating shaft extending along the front-to-back direction, the clamping power device d is mounted on the lower shovel claw b, and is used to drive the upper clamping claw 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 claw 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 claw 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 module 301 is in a dynamic balance state, and the lower shovel claw b remains tilted with the claw tip facing downward; when the lower shovel claw 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 claw b moves downward and upward until the bottom surface of the lower shovel claw b is parallel to the surface of the photovoltaic laminate, and the bonded high-temperature cloth and bus bar are relatively separated from the two ends. At the same time, driven by the lifting mechanism 31, the left clamping module 301 and the right clamping 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 the two bus bars are pulled upward and close when the high-temperature cloth is pulled upward and torn off. At the same time, the top surface of the lower shovel claw 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 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. As for the clamping power device d, it is a conventional power cylinder (electric, pneumatic or hydraulic).

[0054] 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, pre-shoveling claws 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 claws 321 to tilt and keep the shovel tips of each pre-shoveling claw 321 facing downward, wherein the pre-shoveling claws 321 are kept intersecting with the surface of the photovoltaic laminate for pre-shoveling, and the shovel tips are rotated upward by resistance to reduce the inclination angle of the pre-shoveling claws 321, until the bottom surface of the pre-shoveling claws 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 claws 321 is an inclined surface that tilts from back to front and tilts downward, the bottom surface of the pre-shoveling claws 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 busbar can be gradually lifted up as the shovel is gradually inserted, 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 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 busbar is reduced, but also the high-temperature cloth and the busbar can be gradually propped up, and at the same time, they can be synchronously reset to prepare for the next pre-shovel. The pre-shovel power device 322 is a power cylinder arranged in the front-to-back direction, wherein the power of the power cylinder is pneumatic, hydraulic or electric.

[0055] In some specific embodiments, the preheating and blowing 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, and the airflow formed from front to back blows between the high-temperature cloth and the surface of the photovoltaic laminate so that the high-temperature cloth fits the busbar and softens the glue layer between the high-temperature cloth and the surface of the photovoltaic laminate. In short, the blown airflow completely covers the entire area where the high-temperature cloth 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 blowing airflow. Here, by changing the airflow area by height change without changing the direction of the airflow, the purpose of airflow blowing the high-temperature cloth to fit the busbar neatly can be achieved (in other words, the high-temperature cloth is relatively flattened by the airflow so that the clamping height and length are aligned, avoiding the occurrence of different forces on the two busbars and increasing the difficulty of later shaping). This is very important, because the connection between preheating and pre-shoveling has the advantage of avoiding the relative separation of the high-temperature cloth and the busbar, and allowing both to be in a flat state and warp from both ends, while the two are relatively fitted, which is more conducive to later clamping. In order to implement the linkage between the two, the hot purge assembly 33 is movably installed on the frame 311 up and down, and as the pre-shoveling assembly 32 gradually shovels in, the hot purge assembly 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 (relative to the busbar).

[0056] In some specific embodiments, the high temperature cloth sensor 34 obtains the high temperature cloth information between the left clamping head module 301 and the right clamping head module 302 to verify the tearing of the high temperature cloth. 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 (generally a photoelectric sensor), once the high temperature cloth 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 will not occur.

[0057] In addition, the above-mentioned high-temperature cloth recovery unit 4 also includes an auxiliary seat 42 corresponding to the overall structure on one side of the receiving conveyor belt 40 close to the truss 1, and a brush assembly 43 installed on each auxiliary seat 42, wherein the brush assembly 43 corresponds to the movable jaws 30 at the left and right ends. Based on the forward movement of the truss 1, the movable jaws 30 are sent to the top of the receiving conveyor belt 40, and the movable jaws 30 release the high-temperature cloth B, and the high-temperature cloth B slides freely to the receiving conveyor belt 40 and is sent into the recovery box 41; 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 are lowered and aligned with the height of the brush assembly 43, and when the truss 1 retreats, the brush assembly 43 will brush the high-temperature cloth B entangled or stuck on the movable jaws 30 toward the receiving conveyor belt 40, and the high-temperature cloth B that has been brushed off is sent into the recovery box 41 by the receiving conveyor belt 40.

[0058] In some specific embodiments, the receiving conveyor belt 40 is an annular belt, the auxiliary seat 42 can be detached from the side of the annular belt, and the auxiliary seat 42 includes a seat bottom plate 420, and seat side plates 421 that are upward and inwardly inclined from both ends of the seat bottom plate 420, and the brush assembly 43 is symmetrically installed on the seat side plates 421 on the left and right sides, and the brush assembly 43 includes a bristle seat 430 and bristles 431 installed on the bristle seat 430, wherein the bristle seat 430 can be adjusted and assembled up and down along the extension direction of the seat side plates 421; the bristles 430 are perpendicular to the seat side plates 421 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.

[0059] In summary, after adopting the photovoltaic high-temperature cloth removal and recycling system, the high-temperature cloth and the busbar are preheated and pre-shoveled successively or simultaneously, wherein the preheating is to blow the high-temperature cloth through the hot air flow to relatively separate the high-temperature cloth and the surface of the photovoltaic laminate, and the hot air can also soften the glue layer at the lead-out hole, and the pre-shovel is to pre-shovel from both ends and from back to front to gradually lift the high-temperature cloth and the busbar upward from both ends; then use the movable clamp to clamp at the height aligned with the emerging end and form a force center to lift the high-temperature cloth; finally, based on the forward movement of the truss, the movable clamp and the high-temperature cloth are sent to the receiving conveyor belt The movable jaw releases the high-temperature cloth, and the high-temperature cloth slides freely onto the receiving conveyor belt and is sent into the recycling box. At the same time, if the high-temperature cloth sensor obtains that the high-temperature cloth has not slipped off the movable jaw, the movable jaw descends and is aligned with the height of the brush assembly. During the retreat of the truss, the brush assembly will brush the high-temperature cloth entangled or stuck on the movable jaw toward the receiving conveyor belt, and the high-temperature cloth that has been brushed off is sent into 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; it is also convenient for the movable jaw to clamp the high-temperature cloth at the height of The two protruding ends are aligned and the middle of the rubber layer is used as the force center for tearing, 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; 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 clamping claw is brushed to the material collection conveyor belt and collected by the recycling material box, so as to avoid the high-temperature cloth being unable to break away from the movable clamping claw and affecting the tearing of the next piece of high-temperature cloth; the third aspect is based on the setting of the truss and the lifting, which can meet the movement in the front and back and up and down directions, among which the high-temperature cloth is implemented more smoothly under the guidance of the lifting track. Tearing off, the high-temperature cloth tearing unit and the busbar shaping unit arranged in the front and rear 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; the fourth aspect of the pre-shoveling structural design can gradually lift up the high-temperature cloth and the busbar as the shovel is gradually inserted, 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-shoveling 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 support the high-temperature cloth and the busbar upwards, and can also be reset synchronously to prepare for the next pre-shoveling;In the fifth aspect, the design of the preheating and purge component forms an airflow from front to back that blows between the high-temperature cloth and the surface of the photovoltaic laminate so that the high-temperature cloth fits the busbar and softens the glue 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 preheating and purge component. Without changing the direction of the airflow, the airflow area is changed by height changes, and the pre-shovel is used to make the high-temperature cloth fit the busbar relatively flat, 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 fit the busbar neatly (in other words, the high-temperature cloth is relatively flattened by the airflow so that the clamping height and length are 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, so as to tear the high-temperature cloth while applying relatively balanced upward pulling force to the two busbars; the seventh aspect is to use the matching mode of the rack and the running gear, combined with the slide rail to realize the simultaneous tearing of the high-temperature cloth by multiple integral structures, and realize the simultaneous unloading of the high-temperature cloth 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. ;

It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
