Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a glass stripping device for a single-glass photovoltaic module. Background Art

[0002] Photovoltaics is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic panel components are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon), including glass plates, EVA adhesive layers, battery cells, backplanes, junction boxes and frames. More than 90% of the materials can be recycled and reused, with considerable recycling value and high economic profits. Therefore, photovoltaic components that have reached the end of their life need to be recycled, which not only alleviates the shortage of raw materials for photovoltaic devices to a certain extent, but also avoids pollution to the environment.

[0003] At present, for the recycling of photovoltaic modules, the existing technology generally adopts a mechanical separation method to disassemble and recycle the glass in the photovoltaic modules. That is to say, during the transmission process of the photovoltaic modules, the photovoltaic modules are squeezed by crushing rollers to break the glass in the photovoltaic modules, and then the broken glass on the photovoltaic modules is scraped off by a separation device (such as a brush roller) to achieve glass peeling and recycling.

[0004] However, during the above-mentioned stripping process, the photovoltaic modules are squeezed by the crushing rollers, so that a large amount of glass fragments are generated on the surface of the photovoltaic modules. As the photovoltaic modules are transmitted and the crushing rollers continue to squeeze the photovoltaic modules, the glass fragments are likely to accumulate and cause the risk of material jamming. The crushing rollers or the transmission device of the photovoltaic modules need to be disassembled to clean the glass fragments, which is cumbersome and inefficient. In addition, when scraping, there is a high probability that the glass fragments will adhere to the battery cell for the second time, resulting in unsatisfactory separation of the glass and the battery cell. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new glass stripping device for single-glass photovoltaic modules.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] A glass stripping device for a single-glass photovoltaic module, the photovoltaic module includes a cell layer and a glass layer, and the stripping device includes:

[0008] A transmission unit, comprising a base, an upper transmission roller and a lower transmission roller arranged on the base, wherein a transmission channel for transmitting the photovoltaic module from front to back is formed between the upper transmission roller and the lower transmission roller;

[0009] A stripping unit is arranged at the rear side of the transmission unit and comprises a scraping module and a grinding module, wherein the scraping module comprises a scraping blade seat, a scraping blade arranged on the scraping blade seat, and a driver driving the scraping blade seat to reciprocate left and right so as to drive the scraping area formed by the scraping blade to cover the glass layer in the left and right directions; the grinding module comprises a grinding roller arranged above the scraping area and the grinding area formed by the scraping blade can cover the glass layer in the left and right directions, wherein a stripping channel extending up and down and connected to the discharge port of the transmission channel is formed between the scraping blade seat and the grinding roller and the upper transmission roller, and as the upper transmission roller and the lower transmission roller convey the photovoltaic module from front to back, the upper transmission roller synchronously forms a force driving the battery layer to move from bottom to top along the stripping channel, and the glass layer then passes through the scraping area and the grinding area in turn to gradually strip the battery layer;

[0010] The auxiliary unit comprises a power module, wherein the power module drives the transmission unit and the stripping unit to move toward or away from each other, so as to drive the transmission channel and the stripping channel to connect with or move away from each other.

[0011] According to a specific implementation and preferred aspect of the present invention, the thickness of the photovoltaic module is D1, and the thickness of the cell layer is D2; the thickness of the stripping channel corresponding to the scraper seat is d1, and the thickness of the stripping channel corresponding to the grinding roller is d2, wherein D2≤d1<D1, d2=D2. Here, by controlling the thickness of the two parts in the stripping channel, it is ensured that the photovoltaic module enters the grinding area based on the glass layer being partially or completely scraped in the scraping area, and at the same time, it is ensured that the glass layer can be completely removed after the cell layer passes through the grinding roller.

[0012] According to another specific implementation and preferred aspect of the present invention, when the transmission channel is connected to the stripping channel, the photovoltaic module keeps the glass layer facing downward and enters the stripping channel horizontally and moves backward and upward. Here, as the glass is stripped, the battery layer keeps moving upward, and the glass fragments can be discharged downward under their own weight to avoid re-contacting and adhering to the battery layer.

[0013] Preferably, the scraper seat is formed with a guide surface extending obliquely from the front end to the rear and upward. As the transmission channel transmits the photovoltaic module from the front to the rear, after the photovoltaic module passes through the scraping area, the cell layer or the remaining part of the cell layer and the glass layer moves along the guide surface between the upper transmission roller and the grinding roller. Here, by providing the guide surface, the probability of the photovoltaic module successfully entering between the upper transmission roller and the grinding roller is increased.

[0014] Specifically, when the photovoltaic module is transported horizontally, the lower edge of the guide surface is flush with the bottom surface of the battery layer, or the lower edge of the guide surface is located between the top surface and the bottom surface of the glass layer.

[0015] Preferably, the scraper seat is also formed with an inclined surface extending obliquely from the front end surface to the rear and downward, wherein the inclined surface is separated from the roller surface of the lower transmission roller and forms a waste discharge channel extending obliquely from the front to the rear and downward for discharging glass debris. Here, it is convenient to discharge the glass debris generated by scraping, and the probability of glass debris accumulation and causing material jamming is avoided.

[0016] Preferably, the stripping unit further comprises a waste discharge trough fixed relative to the scraper seat, the waste discharge trough extending from front to back and tilting downward, wherein the front end of the waste discharge trough is located directly below the outlet of the waste discharge channel and the grinding area, thereby facilitating the centralized collection and discharge of glass debris.

[0017] According to another specific implementation and preferred aspect of the present invention, there are multiple scrapers which are spaced and distributed side by side on the scraper seat along the left-right direction, thereby improving the scraping efficiency.

[0018] Preferably, a plurality of mounting grooves corresponding to the plurality of blades are formed on the blade seat, wherein each mounting groove extends backward from the front end surface of the blade seat, and the plurality of blades are inserted into the mounting grooves one by one and keep the blade heads protruding forward from the blade seat. As the photovoltaic module is transmitted from front to back, the blade seat moves synchronously and drives the plurality of blades to scrape the glass layer.

[0019] According to another specific implementation and preferred aspect of the present invention, the driver includes guide rails and connecting rods extending left and right respectively, and a driving motor whose output shaft extends along the front-to-back direction, wherein the blade seat is slidably connected to the guide rails, and a connecting module is fixedly provided at the rear end of the blade seat, one end of the connecting rod is rotatably connected to the connecting module, and the other end is sleeved on the output shaft of the driving motor and performs eccentric movement, and as the output shaft of the driving motor rotates, the connecting rod synchronously drives the blade seat to reciprocate along the guide rails.

[0020] According to another specific implementation and preferred aspect of the present invention, the direction of the grinding roller is the same as that of the upper transfer roller, and the rotation speed of the grinding roller is greater than that of the upper transfer roller. Here, based on the speed difference between the grinding roller and the upper transfer roller, the grinding roller can ensure the removal effect of the residual glass layer on the surface of the battery cell layer while realizing the upward transfer of the battery cell layer. At the same time, the diameter of the upper transfer roller is 1.5 to 2.5 times the diameter of the grinding roller, and generally 1.8 to 2.3 times is most suitable. Under the setting of this size roller, it is not only conducive to the grinding and removal of the residual glass layer, but also in the peeling process, it can facilitate the battery cell layer to deform toward the grinding roller while being conveyed upward, so as to improve the peeling quality and facilitate the output and collection of the battery cell layer. It should be noted that when the battery cell layer enters the peeling channel for transmission, its power comes from: 1. The horizontal transmission force of the upper transmission roller and the lower transmission roller on the battery cell layer; 2. The upward driving force of the upper transmission roller on the battery cell layer, thereby overcoming the force of the grinding roller on the surface glass of the battery cell layer to peel downward. In addition, due to the difference in force direction on the two sides of the battery cell layer in the peeling channel, the battery cell layer can gradually deform toward the side of the grinding roller after outputting the peeling channel, and finally the battery cell layer can be removed by manual or robotic traction.

[0021] In other specific embodiments, the rotation direction of the grinding roller is opposite to that of the upper transfer roller, that is, while the grinding roller peels off the residual glass on the surface of the battery layer, the grinding roller and the upper transfer roller synchronously apply an upward transmission force to the battery layer.

[0022] Preferably, the center of the grinding roller is at the same height as the center of the upper transfer roller, and the cell layer or the remaining part of the cell layer and the glass layer passes vertically upward between the grinding roller and the upper transfer roller. That is, when the cell layer or the remaining part of the cell layer and the glass layer passes vertically upward between the grinding roller and the upper transfer roller, the upper transfer roller synchronously contacts the cell layer in the horizontal and vertical directions, that is, when the cell layer is transferred from front to back, the upper transfer roller provides the cell layer with horizontal and vertical transfer force, ensuring that the cell layer is transferred stably and smoothly output from the peeling channel; at the same time, the grinding roller turns in the same direction as the upper transfer roller to achieve a vertical downward grinding force on the glass layer, so as to peel and remove the glass layer downward.

[0023] Preferably, the grinding module further includes a guide roller disposed below the grinding roller, and the battery sheet layer moves toward the guide roller under its own weight after being output from the peeling channel. Here, the guide roller supports and guides the battery sheet layer output from the peeling channel, so that the staff can collect it easily.

[0024] According to another specific implementation and preferred aspect of the present invention, the power module includes an auxiliary rail extending in the front-to-back direction and a power device, wherein the base is slidably connected to the auxiliary rail, and the power device drives the base to slide forward and backward along the auxiliary rail to approach or move away from the stripping unit. Here, in the event of a material jam, the base drives the upper and lower transmission rollers to move forward and backward, and the photovoltaic module can be synchronously pulled out of the stripping unit, which is convenient for cleaning glass fragments while reducing the probability of cell damage.

[0025] In addition, a guide groove extending from left to right and obliquely backward is formed on the base; the power device includes tracks extending left and right, a sliding module slidably connected to the track, and a cylinder driving the sliding module to reciprocate left and right along the track, wherein the sliding module has a sliding end inserted in the guide groove, and as the sliding module moves left and right, the sliding end moves along the guide groove and drives the base to move forward and backward synchronously. The structure is simple and easy to install and implement.

[0026] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0027] The prior art squeezes the photovoltaic module through the crushing roller, so that a large number of glass fragments are generated on the surface of the photovoltaic module. With the transmission of the photovoltaic module and the continuous squeezing of the photovoltaic module by the crushing roller, the glass fragments are likely to accumulate and cause the risk of material jamming. The crushing roller or the transmission device of the photovoltaic module needs to be disassembled to clean the glass fragments, which is cumbersome and inefficient. In addition, when scraping, there is a high probability that the glass fragments will re-adhere to the battery cell, resulting in an unsatisfactory separation effect between the glass and the battery cell. The present application designs the structure of the glass stripping device for the single-glass photovoltaic module as a whole, and cleverly solves the shortcomings and defects of the prior art. After adopting the glass stripping device, first, the transmission channel formed by the upper and lower transmission rollers is used to transmit from front to back. The photovoltaic module allows the photovoltaic module to enter the stripping channel, and then the scraping area formed by the scraper is driven by the left and right reciprocating motion of the scraper seat to scrape the glass layer in the photovoltaic module, so as to achieve the preliminary stripping of the glass layer from the cell layer; then the photovoltaic module passes through the grinding area formed by the grinding roller to achieve the grinding and removal of the remaining glass layer, so as to achieve the complete stripping of the glass layer from the cell layer, and under the force formed by the synchronous movement of the grinding roller and the upper transmission roller or the lower transmission roller, the cell layer after the glass layer is stripped moves toward the stripping channel outlet; in addition, the transmission unit and the stripping unit are driven to move toward or away from each other by the power module, so as to drive the transmission channel and the stripping channel to connect or move away from each other, so that the stripping equipment can be flexibly switched between the normal working state and the material jamming and cleaning state. Therefore, compared with the prior art, the present invention, on the one hand, combines scraping and grinding. During the transmission of the photovoltaic modules from front to back, the photovoltaic modules gradually move from bottom to top and the glass layer is initially peeled off by scraping. Then, the remaining glass layer is completely removed by grinding. This greatly improves the efficiency and quality of glass peeling, avoids secondary adhesion, and effectively reduces the glass residue rate. On the other hand, based on the cooperation between the upper and lower transmission rollers and the scraping module and the grinding module, the transmission unit is separated from the peeling unit to clean up the accumulated glass fragments, thereby quickly eliminating the problem of material jamming. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figures 1 to 5 As shown, the glass stripping device for the single-glass photovoltaic module involved in this embodiment includes a transmission unit 1, a stripping unit 2, and an auxiliary unit 3; the photovoltaic module G of this embodiment includes a cell layer G1 and a glass layer G2.

[0044] Specifically, the transmission unit 1 includes a base 10, an upper transmission roller 11 and a lower transmission roller 12 arranged on the base 10 at an interval, wherein a transmission channel t1 for transmitting the heated photovoltaic module G from front to back is formed between the upper transmission roller 11 and the lower transmission roller 12, wherein when the photovoltaic module G is in the transmission channel t1, the photovoltaic module G is horizontally transmitted from front to back, and the glass layer G2 is kept facing downward. The upper transmission roller 11 and the lower transmission roller 12 are driven by sprockets, which is a conventional technology and will not be described here.

[0045] In this example, the stripping unit 2 is arranged at the rear side of the transmission unit 1, and includes a scraping module 20 and a grinding module 21, wherein the scraping module 20 includes a scraping blade seat 200, a scraping blade 201 arranged on the scraping blade seat 200, and a driver 202 that drives the scraping blade seat 200 to reciprocate left and right so that the scraping area formed by the scraping blade 201 can cover the glass layer G2 in the left and right directions; the grinding module 21 includes a scraping blade seat 200, and a scraping blade 201 arranged on the upper side of the scraping blade 201. The scraping area formed by the scraping blade 201 can cover the glass layer G2 in the left and right directions. The grinding roller 210 of the glass layer G2, wherein a peeling channel t2 extending up and down and connected to the discharge port of the transmission channel t1 is formed between the scraper seat 200 and the grinding roller 210 and the upper transmission roller 11. As the upper transmission roller 11 and the lower transmission roller 12 transport the photovoltaic module G from front to back, the upper transmission roller 11 synchronously forms a force to drive the battery cell G1 layer to move from bottom to top along the peeling channel t2, and the glass layer G2 then passes through the scraping area and the grinding area in turn to gradually peel off the battery cell layer G1 downward.

[0046] In some specific embodiments, the photovoltaic module G keeps the glass layer G2 facing downward and enters the stripping channel t2 horizontally and moves backward and upward; the thickness of the photovoltaic module G is D1, and the thickness of the battery layer G1 is D2; the thickness of the stripping channel t2 corresponding to the scraper seat 200 is d1, and the thickness of the stripping channel t2 corresponding to the grinding roller 210 is d2, wherein D2≤d1<D1, d2=D2, and in this embodiment, preferably, d1=d2=D2, so that the glass layer G2 can be completely removed during scraping, and when the battery layer G1 enters between the grinding roller 210 and the upper transmission roller 11, the glass fragments that are secondarily bonded to the battery layer G1 are completely removed by the grinding roller 210.

[0047] The blade seat 200 is formed with a guide surface m1 extending obliquely from the front end surface to the rear and upward, and an inclined surface m2 extending obliquely from the front end surface to the rear and downward, wherein when the photovoltaic module G is horizontally conveyed, the lower edge of the guide surface m1 is flush with the bottom surface of the battery layer G1, or the lower edge of the guide surface m1 is located between the top surface and the bottom surface of the glass layer G2. In other words, the height of the lower edge of the guide surface m1 is determined according to the actual scraping thickness of the blade 201, so as to ensure that the remaining portion of the battery layer G1 or the battery layer G1 and the glass layer G2 after scraping is It smoothly contacts the guide surface m1, so as the transmission channel t1 transports the photovoltaic module G from front to back, after the photovoltaic module G passes through the scraping area, the cell layer G1 or the remaining part of the cell layer G1 and the glass layer G2 moves along the guide surface m1 between the upper transmission roller 11 and the grinding roller 210; the inclined surface m2 is separated from the roller surface of the lower transmission roller 12 and forms a waste discharge channel t3 extending from front to back and downward to discharge glass debris, wherein the waste discharge channel t3 is gradually widened from top to bottom to ensure smooth chip discharge and avoid blockage.

[0048] At the same time, the stripping unit 2 also includes a waste discharge trough 203 fixed relatively to the scraper seat 200, and the waste discharge trough 203 extends from front to back and tilted downward, wherein the front end of the waste discharge trough 203 is located directly below the outlet of the waste discharge channel t3 and the grinding area. In order to facilitate centralized waste discharge, the waste discharge trough 203 is gradually narrowed from top to bottom. The waste discharge trough 203 is fixedly connected to the rear end of the scraper seat 200 through a triangular bracket.

[0049] In this example, there are multiple scrapers 201 which are spaced apart and arranged side by side on the scraper seat 200 along the left-right direction.

[0050] In some specific embodiments, a plurality of installation grooves c corresponding to the plurality of blades 201 are formed on the blade seat 200, wherein each installation groove c extends backward from the front end surface of the blade seat 200, and the plurality of blades 201 are inserted into the installation grooves c one by one and keep the blade heads protruding forward from the blade seat 200, and are compressed by the compression bolts. As the photovoltaic module G is transmitted from front to back, the blade seat 200 moves synchronously and drives the plurality of blades 201 to scrape the glass layer G2. The blade 201 is a commercially available product, and its structure is not described in detail here.

[0051] The driver 202 includes a guide rail a0 and a connecting rod a1 extending left and right respectively, and a driving motor a2 whose output shaft extends along the front-back direction, wherein the blade seat 200 is slidably connected to the guide rail a0, and a connecting module k is fixedly provided at the rear end of the blade seat 200, one end of the connecting rod b1 is rotatably connected to the connecting module k, and the other end is sleeved on the output shaft of the driving motor a2 and makes eccentric motion around the center line of the output shaft of the driving motor b2. As the output shaft of the driving motor a2 rotates, the connecting rod a1 synchronously drives the blade seat 200 to reciprocate along the guide rail a0.

[0052] The rotation speed of the grinding roller 210 is greater than that of the upper transfer roller 11. Here, based on the speed difference between the grinding roller and the upper transfer roller, the grinding roller can ensure the removal effect of the residual glass layer on the surface of the battery cell layer while realizing the upward transfer of the battery cell layer. At the same time, the diameter of the upper transfer roller 11 is 1.5 to 2.5 times the diameter of the grinding roller 210. Generally, 1.8 to 2.3 times is most suitable. In this embodiment, the diameter of the upper transfer roller 11 is 1.83 times the diameter of the grinding roller 210. Under this setting of large and small rollers, it is not only conducive to the grinding and removal of the residual glass layer, but also facilitates the battery cell layer to deform toward the grinding roller during the upward transfer during the peeling process, so as to improve the peeling quality and facilitate the output and collection of the battery cell layer.

[0053] The center of the grinding roller 210 is at the same height as the center of the upper conveying roller 11, and the remaining portion of the cell layer or the cell layer and the glass layer vertically passes upward between the grinding roller 210 and the upper conveying roller 11. The grinding roller 210 can be a conventional grinding roller or a metal brush roller, that is, the metal brushes distributed on the surface of the metal brush roller are used to brush the glass remaining on the surface of the cell layer to peel it off.

[0054] For the convenience of implementation, the grinding module 21 further includes a guide roller 211 disposed at the rear lower part of the grinding roller 210. After the battery layer G1 is output from the stripping channel t2, it moves under its own weight toward the guide roller 211. Here, the guide roller supports and guides the battery layer output from the stripping channel, so that the staff can collect it easily.

[0055] In this example, the auxiliary unit 3 includes a power module, wherein the power module drives the transmission unit 1 and the stripping unit 2 to move toward or away from each other, so as to drive the transmission channel t1 and the stripping channel t2 to connect with or move away from each other.

[0056] In some specific embodiments, the power module includes an auxiliary rail 30 extending in the front-to-back direction and a power device 31, wherein the base 10 is slidably connected to the auxiliary rail 30, and the power device 31 drives the base 10 to slide forward and backward along the auxiliary rail 30 to approach or move away from the stripping unit. Here, in the event of a material jam, the base drives the upper and lower transmission rollers to move forward and backward, and the photovoltaic module can be synchronously pulled out of the stripping unit, which is convenient for cleaning glass fragments while reducing the probability of cell damage.

[0057] In addition, a guide groove 100 extending from left to right and obliquely backward is formed on the base 10; the power device 31 includes a track 310 extending left and right, a sliding module 311 slidably connected to the track 310, and a cylinder 312 driving the sliding module 311 to reciprocate left and right along the track 310, wherein the sliding module 311 has a sliding end d inserted in the guide groove 100, and as the sliding module 311 moves left and right, the sliding end d moves along the guide groove 100 and drives the base 10 to move synchronously forward and backward.

[0058] For further convenience of implementation, the base 10 is disposed at both ends of the upper and lower transmission rollers and is respectively formed with guide grooves 100 . Both ends of the sliding module 311 are respectively provided with sliding ends d and are inserted into the corresponding guide grooves 100 .

[0059] In summary, after adopting the glass stripping equipment, first, the photovoltaic module is transmitted from front to back through the transmission channel formed by the upper and lower transmission rollers, so that the photovoltaic module enters the stripping channel, and then the scraping area formed by the scraper is driven by the left and right reciprocating motion of the scraper seat to scrape the glass layer in the photovoltaic module, so as to achieve the preliminary stripping of the glass layer from the cell layer; then the photovoltaic module passes through the grinding area formed by the grinding roller to achieve the grinding and removal of the remaining glass layer, so as to achieve the complete stripping of the glass layer from the cell layer, and under the force formed by the synchronous movement of the grinding roller and the upper transmission roller or the lower transmission roller, the cell layer after the glass layer is stripped moves toward the exit of the stripping channel; in addition, the transmission unit and the stripping unit are driven to move toward or away from each other by the power module, so as to drive the transmission channel and the stripping channel to connect or move away from each other, so that the stripping equipment can flexibly switch between the normal working state and the material jamming and cleaning state.Therefore, compared with the prior art, the present invention combines scraping and grinding. During the transmission of the photovoltaic module from front to back, the photovoltaic module gradually moves from bottom to top and the glass layer is initially peeled off by scraping, and then the remaining glass layer is completely removed by grinding, thereby greatly improving the efficiency and quality of glass peeling, avoiding secondary adhesion, and effectively reducing the glass residue rate. On the other hand, based on the cooperation of the upper and lower transmission rollers with the scraping module and the grinding module, the transmission unit is separated from the peeling unit to clean up the accumulated glass fragments, thereby realizing the rapid elimination of the material jamming problem, and the operation is simple and convenient. Thirdly, by The thickness of the two parts in the stripping channel is controlled to ensure that the photovoltaic module enters the grinding area based on the glass layer being partially or completely scraped in the scraping area, and at the same time, ensure that the glass layer of the battery layer can be completely removed after passing through the grinding roller; fourthly, as the glass is peeled off, the battery layer keeps moving upward, and the glass fragments can be discharged downward under their own weight to avoid re-contact and adhesion to the battery layer; fifthly, by setting a guide surface, the probability of the photovoltaic module successfully entering between the upper transmission roller and the grinding roller is increased; sixthly, by setting a waste discharge channel, it is convenient to discharge the glass fragments generated by scraping. The upper conveyor roller and the grinding roller of the present application are arranged to not only facilitate the grinding and removal of the residual glass layer, but also facilitate the deformation of the battery layer in the direction of the grinding roller during the upward conveyance, so as to improve the peeling quality and facilitate the output and collection of the battery layer; the eighth aspect is that when the battery layer or the remaining part of the battery layer and the glass layer passes vertically upward between the grinding roller and the upper conveyor roller, the upper conveyor roller synchronously contacts the battery layer in the horizontal and vertical directions, that is, when the battery layer is conveyed from front to back, the upper conveyor roller is lifted It provides horizontal and vertical transmission force for the battery layer, ensuring stable transmission of the battery layer and smooth output of the peeling channel; at the same time, the grinding roller turns in the same direction as the upper transmission roller to achieve a vertical downward grinding force on the glass layer, so as to peel and remove the glass layer downward; ninthly, the guide roller is used to support and guide the battery layer outputting the peeling channel to facilitate collection by staff; tenthly, in the event of material jamming, the upper and lower transmission rollers are driven back and forth by the base, so that the photovoltaic module can be synchronously pulled out of the peeling unit, which is convenient for cleaning glass fragments while reducing the probability of battery cell breakage.
