Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a segmented heating and peeling glass stripping system for a single-glass component. 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, back panels, junction boxes and frames. More than 90% of the materials can be recycled and reused, with considerable recycling value and high economic profits. Therefore, single-glass 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 single-glass components, the existing technology generally adopts a mechanical separation method to disassemble and recycle the glass in the single-glass components. That is to say, during the transmission process of the single-glass components, the single-glass components are squeezed by a crushing roller to break the glass in the single-glass components, and then the broken glass on the single-glass components is scraped off by a separation device (such as a brush roller) to achieve glass peeling and recycling.

[0004] However, the above-mentioned stripping process is prone to the following technical defects:

[0005] 1. Before the glass stripping operation of the single-glass module, the glue layer between the glass and the cell needs to be heated in a targeted manner. However, based on traditional equipment, especially in low-temperature environments, the deformation (such as warping, arching, etc.) caused by transportation or previous disassembly operations of the single-glass module is difficult to recover, resulting in the single-glass module being unable to smoothly enter the stripping process and prone to material jamming problems;

[0006] 2. The crushing roller squeezes the single-glass component, causing a large amount of glass fragments to be generated on the surface of the single-glass component. As the single-glass component is transmitted and the crushing roller continues to squeeze the single-glass component, glass fragments are prone to accumulate and cause the risk of material jamming. The crushing roller or the transmission device of the single-glass component 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 adhere to the battery cell for the second time, resulting in unsatisfactory separation of the glass and the battery cell. 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 segmented heating and stripping glass stripping system for single-glass components.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0009] A segmented heating and peeling glass peeling system for a single-glass component, the single-glass component includes a cell layer and a glass layer, and the peeling system includes:

[0010] A heating device, comprising a preheating component, a secondary heating component and a conveyor belt for conveying a single glass component from front to back, wherein the preheating component forms a preheating channel extending forward and backward, the secondary heating component is arranged at the outlet of the preheating channel and the temperature of the formed heating area is higher than the temperature of the preheating channel, the single glass component is placed flat on the conveyor belt with the glass layer facing downward, and as the conveyor belt is conveyed, the single glass component passes through the preheating channel piece by piece and moves to the top of the secondary heating component, and the glass layer is located in the heating area; it should be particularly noted that the reason why the present application adopts the mode of segmented heating is that: first, the temperature required for the battery layer to be heated to be deformable is different from the temperature required for the glue layer between the glass layer and the battery layer to soften (generally speaking, in order to achieve a better peeling effect, the heating temperature required for softening the glue layer is higher); second, energy consumption is saved by segmented heating;

[0011] The stripping device includes a conveying unit, a stripping unit and an auxiliary driving unit. The conveying unit includes a base, an upper roller and a lower roller arranged on the base, and a guide plate located above the conveyor belt, wherein a transmission channel connected with the conveyor belt and transmitting the single glass component from front to back is formed between the upper roller and the lower roller, and the guide plate extends from front to back and downward and then extends horizontally backward, and the guide plate approaches the transmission channel from the rear end; the stripping unit is arranged at the rear side of the conveying unit, and includes a scraping module and a secondary stripping module, wherein the scraping module includes a knife seat, a scraping knife arranged on the knife seat, and a driver driving the knife seat to reciprocate left and right to drive the scraping area formed by the scraping knife to cover the glass layer in the left and right directions The secondary stripping module includes a secondary stripping roller which is arranged above the scraping area and the secondary stripping area formed can cover the glass layer in the left and right directions, wherein a stripping channel which extends up and down and is connected to the discharge port of the transmission channel is formed between the knife seat and the secondary stripping roller and the upper roller, and as the upper roller and the lower roller transport the single glass component from front to back, the upper roller synchronously forms a force which drives the battery cell layer to move from bottom to top along the stripping channel, and the glass layer then passes through the scraping area and the secondary stripping area in turn to gradually strip the battery cell layer downward; the auxiliary driving unit includes a power module, wherein the power module drives the transmission unit and the stripping unit to move towards 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.

[0012] According to a specific implementation and preferred aspect of the present invention, the preheating component includes an oven formed with a preheating channel, heat sources distributed on the inner walls around the preheating channel, and the transmission surface formed by the conveyor belt is divided from front to back into a loading section exposed at the front end of the oven, a preheating section located in the preheating channel, and a heating section exposed at the rear end of the oven and located in the heating area.

[0013] According to another specific implementation and preferred aspect of the present invention, the secondary heating component includes a plurality of heating rods extending left and right and spaced apart in parallel front and back, and the heating area formed by the plurality of heating rods can cover the glass layer.

[0014] According to another specific implementation and preferred aspect of the present invention, the transmission surface formed by the conveyor belt is arranged flush with the top of the lower roller; and / or the conveyor belt is a metal mesh belt.

[0015] According to another specific implementation and preferred aspect of the present invention, the thickness of the single glass component is D1, and the thickness of the cell layer is D2; the thickness of the stripping channel corresponding to the knife seat is d1, and the thickness of the stripping channel corresponding to the secondary stripping 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 single glass component enters the secondary stripping 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 secondary stripping roller.

[0016] According to another specific implementation and preferred aspect of the present invention, when the transmission channel is connected to the peeling channel, the single-glass component keeps the glass layer facing downward and enters the peeling channel horizontally and moves backward and upward. Here, as the glass is peeled, 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.

[0017] Preferably, the knife seat is formed with a guide surface extending obliquely from the front end to the rear and upward. As the transmission channel conveys the single-glass component from front to back, after the single-glass component 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 roller and the secondary stripping roller. Here, by providing the guide surface, the probability of the single-glass component successfully entering between the upper roller and the secondary stripping roller is increased.

[0018] Specifically, when the single-glass component 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.

[0019] Preferably, the knife 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 spaced from the roller surface of the lower 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 avoid the probability of glass debris accumulating and causing material jamming.

[0020] Preferably, the stripping unit further comprises a waste discharge hopper fixed relative to the knife holder, the waste discharge hopper extending from front to back and tilting downward, wherein the front end of the waste discharge hopper is located directly below the outlet of the waste discharge channel and the secondary stripping area, thereby facilitating the centralized collection and discharge of glass debris.

[0021] According to another specific implementation and preferred aspect of the present invention, there are multiple scrapers which are spaced and arranged side by side on the blade holder along the left-right direction, thereby improving the scraping efficiency.

[0022] Preferably, a plurality of mounting grooves corresponding to the plurality of scrapers are formed on the knife seat, wherein each mounting groove extends backward from the front end surface of the knife seat, and the plurality of scrapers are inserted into the mounting grooves one by one and keep the knife heads protruding forward from the knife seat. As the single glass component is transmitted from front to back, the knife seat moves synchronously and drives the plurality of scrapers to scrape the glass layer.

[0023] 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 tool holder is slidably connected to the guide rails, and a connecting module is fixedly provided at the rear end of the tool holder, 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 motion, and as the output shaft of the driving motor rotates, the connecting rod synchronously drives the tool holder to reciprocate along the guide rails.

[0024] According to another specific implementation and preferred aspect of the present invention, the direction of the secondary peeling roller is the same as that of the upper roller, and the rotation speed of the secondary peeling roller is greater than that of the upper roller. Here, based on the speed difference between the secondary peeling roller and the upper roller, the removal effect of the residual glass layer on the surface of the battery cell layer by the secondary peeling roller is ensured while the battery cell layer is conveyed upward. At the same time, the diameter of the upper roller is 1.5 to 2.5 times the diameter of the secondary peeling roller, and generally 1.8 to 2.3 times is most suitable. Under the setting of this size of roller, it is not only conducive to the grinding and removal of the residual glass layer, but also during the peeling process, it can facilitate the battery cell layer to deform toward the secondary peeling roller during the upward transmission, 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 layer enters the peeling channel for transmission, its power comes from: 1. The horizontal transmission force of the upper roller and the lower roller on the battery layer; 2. The upward driving force of the upper roller on the battery layer, thereby overcoming the downward peeling force of the secondary peeling roller on the surface glass of the battery layer. In addition, due to the force difference on the two sides of the battery layer in the peeling channel, the battery layer can gradually deform toward the side of the secondary peeling roller after outputting the peeling channel, and finally the battery layer can be taken out by manual or robotic traction.

[0025] Preferably, the center of the secondary peeling roller is at the same height as the center of the upper roller, and the cell layer or the remaining part of the cell layer and the glass layer passes vertically upward between the secondary peeling roller and the upper roller. That is, when the cell layer or the remaining part of the cell layer and the glass layer passes vertically upward between the secondary peeling roller and the upper roller, the upper roller synchronously contacts the cell layer in the horizontal and vertical directions, that is, when the cell layer is conveyed from front to back, the upper roller provides the horizontal and vertical conveying force of the cell layer to ensure the stable conveying of the cell layer and the smooth output of the peeling channel; at the same time, the secondary peeling roller turns in the same direction as the upper roller to realize the vertical downward grinding force on the glass layer, so as to peel and remove the glass layer downward.

[0026] Preferably, the secondary stripping module also includes a guide roller arranged below and behind the secondary stripping roller, and the battery cell layer moves in the direction of the guide roller under its own weight after being output from the stripping channel. Here, the guide roller is used to support and guide the battery cell layer output from the stripping channel to facilitate collection by staff. According to another specific implementation and preferred aspect of the present invention, the power module includes an auxiliary guide rail extending along the front-to-back direction and a power device, wherein the base is slidably connected to the auxiliary guide rail, and the power device drives the base to slide forward and backward along the auxiliary guide rail to approach or move away from the stripping unit. Here, in the event of material jamming, the upper and lower rollers are driven forward and backward by the base to synchronously pull the single-glass component out of the stripping unit, which is convenient for cleaning glass fragments while reducing the probability of battery cell breakage.

[0027] 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.

[0028] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0029] The prior art squeezes the single-glass component by a crushing roller, so that a large amount of glass fragments are generated on the surface of the single-glass component. As the single-glass component is transmitted and the crushing roller continues to squeeze the single-glass component, the glass fragments are likely to accumulate and cause the risk of material jamming. The crushing roller or the transmission device of the single-glass component 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 comprehensively designs the structure of the segmented heating and peeling glass peeling system for the single-glass component, ingeniously solving the shortcomings and defects of the prior art. After adopting the glass peeling system, first, the single-glass component is conveyed from front to back by a conveyor belt, wherein the single-glass component passes through a preheating channel formed by surround heating and moves to the top of the secondary heating component, keeping the glass layer located at the heating channel formed by the secondary heating component. hot area; then, during the continuous transmission of the conveyor belt, the single-glass component continues to enter the transmission channel formed by the upper and lower rollers backwards, and is transmitted from front to back along the transmission channel, so that the single-glass component enters the stripping channel, and the scraping area formed by the scraper is driven by the left and right reciprocating motion of the knife holder to scrape the glass layer in the single-glass component, so as to achieve the preliminary stripping of the glass layer from the battery cell layer; then, the single-glass component passes through the secondary stripping area formed by the secondary stripping 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 battery cell layer, and under the force formed by the synchronous movement of the secondary stripping roller and the upper roller or the lower roller, the battery 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 to connect or move away from the stripping channel, so that the stripping system 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, is based on a preheating channel and a heating area formed for the glass layer, so that the single-glass component is heated in sections during transportation. The preheated battery cell is easy to deform to flexibly adapt to changes in the transportation direction, and at the same time, the glue layer between the battery cell and the glass is gradually softened to facilitate precise stripping operations; on the other hand, through the combination of scraping and grinding, based on the single-glass component being transported from front to back, the single-glass component gradually moves from bottom to top and the glass layer is initially stripped by scraping, and then the remaining glass layer is completely removed by grinding, which greatly improves the efficiency and quality of glass stripping, avoids secondary adhesion, and effectively reduces the glass residue rate; in addition, based on the cooperation of the upper and lower rollers with the scraping module and the secondary stripping module, the conveying unit and the stripping unit are separated to clean up the accumulated glass fragments, so as to quickly eliminate the jamming problem, and the operation is simple and convenient.

[0047] like Figures 1 to 8 As shown, the segmented heating and peeling glass peeling system for the single-glass component involved in this embodiment includes a peeling device ① and a heating device ②. The single-glass component G of this embodiment includes a cell layer G1 and a glass layer G2.

[0048] Specifically, the peeling device ① includes a conveying unit 1, a peeling unit 2, and an auxiliary driving unit 3.

[0049] The conveying unit 1 includes a base 10, an upper roller 11 and a lower roller 12 arranged on the base 10 at an interval, wherein a transmission channel t1 for transmitting the heated single-glass component G from front to back is formed between the upper roller 11 and the lower roller 12. When the single-glass component G is in the transmission channel t1, the single-glass component G is horizontally transmitted from front to back, and the glass layer G2 is kept facing downward. The upper roller 11 and the lower roller 12 are driven by sprockets, which is a conventional technology and will not be described here.

[0050] In this example, the stripping unit 2 is arranged at the rear side of the conveying unit 1, and includes a scraping module 20 and a secondary stripping module 21, wherein the scraping module 20 includes a knife seat 200, a scraping knife 201 arranged on the knife seat 200, and a driver 202 that drives the knife seat 200 to reciprocate left and right so that the scraping area formed by the scraping knife 201 can cover the glass layer G2 in the left and right directions; the secondary stripping module 21 includes a secondary stripping roller 210 that is arranged above the scraping area and the secondary stripping area formed can cover the glass layer G2 in the left and right directions, wherein a stripping channel t2 extending up and down and connected to the discharge port of the transmission channel t1 is formed between the knife seat 200 and the secondary stripping roller 210 and the upper roller 11, and as the upper roller 11 and the lower roller 12 convey the single glass component G from front to back, the upper roller 11 synchronously forms a force that drives the battery layer G1 to move from bottom to top along the stripping channel t2, and the glass layer G2 then passes through the scraping area and the secondary stripping area in sequence to gradually strip the battery layer G1 downward.

[0051] In some specific embodiments, the single-glass component G keeps the glass layer G2 facing downward and enters the peeling channel t2 horizontally and moves backward and upward; the thickness of the single-glass component G is D1, and the thickness of the battery layer G1 is D2; the thickness of the peeling channel t2 corresponding to the knife seat 200 is d1, and the thickness of the peeling channel t2 corresponding to the secondary peeling roller 210 is d2, wherein D2≤d1<D1, d2=D2, in this embodiment, preferably, d1=d2=D2, so that the glass layer G2 can be completely scraped off during scraping, and when the battery layer G1 enters between the secondary peeling roller 210 and the upper roller 11, the glass fragments secondarily bonded to the battery layer G1 are completely removed by the secondary peeling roller 210.

[0052] The blade holder 200 is formed with a guide surface m1 extending obliquely from the front end to the rear and upward, and an inclined surface m2 extending obliquely from the front end to the rear and downward, wherein when the single-glass component G is horizontally conveyed, the lower edge of the guide surface m1 is flush with the bottom surface of the cell 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 scraper 201, so as to ensure that the remaining portion of the cell layer G1 or the cell layer G1 and the glass layer G2 after scraping is It smoothly contacts the guide surface m1, so as the transmission channel t1 transmits the single-glass component G from front to back, after the single-glass component G passes through the scraping area, the battery layer G1 or the remaining part of the battery layer G1 and the glass layer G2 moves along the guide surface m1 to between the upper roller 11 and the secondary peeling roller 210; the inclined surface m2 is separated from the roller surface of the lower roller 12 and forms a waste discharge channel t3 extending from front to back and downward to discharge glass fragments, wherein the waste discharge channel t3 is gradually widened from top to bottom to ensure smooth chip discharge and avoid blockage.

[0053] At the same time, the stripping unit 2 also includes a waste discharge hopper 203 fixed relatively to the knife holder 200, and the waste discharge hopper 203 extends from front to back and tilted downward, wherein the front end of the waste discharge hopper 203 is located directly below the outlet of the waste discharge channel t3 and the secondary stripping area. In order to facilitate centralized waste discharge, the waste discharge hopper 203 is gradually narrowed from top to bottom. The waste discharge hopper 203 is fixedly connected to the rear end of the knife holder 200 through a triangular bracket.

[0054] In this example, there are multiple scrapers 201 which are spaced apart and arranged side by side on the blade holder 200 along the left-right direction.

[0055] In some specific embodiments, a plurality of installation grooves c corresponding to the plurality of scrapers 201 are formed on the knife holder 200, wherein each installation groove c extends backward from the front end surface of the knife holder 200, and the plurality of scrapers 201 are inserted into the installation grooves c one by one and keep the blade heads protruding forward from the knife holder 200, and are compressed by the compression bolts. As the single glass assembly G is transmitted from front to back, the knife holder 200 moves synchronously and drives the plurality of scrapers 201 to scrape the glass layer G2. The scrapers 201 are commercially available products, and their structure is not described in detail here.

[0056] 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 tool holder 200 is slidably connected to the guide rail a0, and a connecting module k is fixedly provided at the rear end of the tool holder 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 tool holder 200 to reciprocate along the guide rail a0.

[0057] The rotation speed of the secondary peeling roller 210 is greater than that of the upper roller 11. Here, based on the rotation speed difference between the secondary peeling roller and the upper roller, the secondary peeling roller can ensure the removal effect of the residual glass layer on the surface of the battery cell layer while realizing the upward transmission of the battery cell layer. At the same time, the diameter of the upper roller 11 is 1.5 to 2.5 times the diameter of the secondary peeling roller 210. Generally, 1.8 to 2.3 times is most suitable. In this embodiment, the diameter of the upper roller 11 is 1.83 times the diameter of the secondary peeling 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 secondary peeling roller during the upward transmission during the peeling process, so as to improve the peeling quality and facilitate the output and collection of the battery cell layer.

[0058] The center of the secondary stripping roller 210 is at the same height as the center of the upper roller 11, and the cell layer or the remaining part of the cell layer and the glass layer vertically passes upward between the secondary stripping roller 210 and the upper roller 11. The secondary stripping 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 strip it.

[0059] For the convenience of implementation, the secondary stripping module 21 also includes a guide roller 211 arranged at the rear and lower part of the secondary stripping roller 210. After the battery layer G1 is output from the stripping channel t2, it moves downward under its own weight in the direction of the guide roller 211. Here, the guide roller supports and guides the battery layer output from the stripping channel to facilitate collection by the staff. It should be particularly noted that when the battery layer G1 enters the stripping channel t2 for transmission, its power comes from: 1. The horizontal transmission force of the upper roller 11 and the lower roller 12 on the battery layer G1; 2. The upward driving force of the upper roller 11 on the battery layer G1, thereby overcoming the downward peeling force of the secondary stripping roller 210 on the surface glass of the battery layer. In addition, due to the difference in the force direction of the two sides of the battery layer G1 in the stripping channel t2, the battery layer G1 can be gradually deformed and fall on the guide roller 211 after outputting the stripping channel t2. Finally, the battery layer G1 can be taken out by manual or mechanical traction.

[0060] In this example, the auxiliary driving 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.

Here, in the event of a material jam, the base drives the upper and lower rollers to move forward and backward, and the single-glass component can be synchronously pulled out of the stripping unit, which is convenient for cleaning glass fragments and reduces the probability of cell damage.

[0062] 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.

[0063] In order to further facilitate implementation, the base 10 is disposed at both ends of the upper and lower 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 .

[0064] In this example, the heating device ② is arranged in front of the stripping device ①, and includes a preheating component 4, a secondary heating component 5, and a conveyor belt 6 for conveying the single glass component from front to back, wherein the preheating component 4 forms a preheating channel t4 extending forward and backward, the secondary heating component 5 is arranged at the exit of the preheating channel t4 and the temperature of the formed heating area q is higher than the temperature of the preheating channel t4, the single glass component G is placed flat on the conveyor belt 6 from the glass layer G2 downward, and as the conveyor belt 6 is conveyed, the single glass component G passes through the preheating channel t4 piece by piece and moves to the top of the secondary heating component 5, and the glass layer G2 is located in the heating area q formed by the secondary heating component 5. As for the heating temperature formed by the preheating channel t4 and the heating area q, it is set according to the actual battery cell material and the temperature required for the adhesive layer between the glass layer and the battery cell layer to reach the peelable degree.

[0065] In some specific embodiments, the preheating component 4 includes an oven 40 formed with a preheating channel t4, and heat sources distributed on the inner walls around the preheating channel t4; the conveyor belt 6 is connected to the transmission channel t1 formed between the upper roller 11 and the lower roller from the rear end, and the transmission surface formed by the conveyor belt 6 is divided from front to back into a loading section 60 exposed at the front end of the oven, a preheating section located in the preheating channel t4 (not shown in the figure, but it is not difficult to imagine), and a heating section 61 exposed at the rear end of the oven 40 and located in the heating area q. The transmission surface formed by the conveyor belt 6 is set flush with the top of the lower roller 12, and the conveyor belt 6 adopts a metal mesh belt and is driven by a sprocket. At the same time, the conveying unit 1 also includes a guide plate 13 located above the conveyor belt 6 and close to the transmission channel t1 from the rear end, wherein the guide plate 13 extends from the front to the back and obliquely downward and then extends horizontally backward, and four guide plates 13 are arranged and spaced side by side on the left and right, so that after the single glass component G is preheated and reheated, it can be accurately entered into the transmission channel t1 in a flat state after being shaped by the guide plate 13 to perform the glass stripping operation.

[0066] In addition, the secondary heating component 5 is arranged in the heating section 61 and includes a plurality of heating rods 50 extending left and right and spaced apart side by side in front and back. The heating area q formed by the plurality of heating rods 50 can cover the glass layer G2 to ensure that when the single glass component moves to the heating section 61, the glass layer G2 is entirely within the heating area q.

[0067] In summary, after adopting the glass stripping system, first, the single-glass component is transported from front to back by the conveyor belt, wherein the single-glass component passes through the preheating channel formed by the surrounding heating and moves to the top of the secondary heating component, so that the glass layer is kept in the heating area formed by the secondary heating component; then, during the continuous transport of the conveyor belt, the single-glass component continues to enter the transmission channel formed by the upper and lower rollers backward, and is transported from front to back along the transmission channel, so that the single-glass component enters the stripping channel, and the scraping area formed by the scraper is driven by the reciprocating left and right motion of the knife holder to scrape the glass layer in the single-glass component , to achieve preliminary peeling of the glass layer off the cell layer; then the single glass component passes through the secondary peeling area formed by the secondary peeling roller to achieve grinding and removal of the remaining glass layer, to achieve complete peeling of the glass layer off the cell layer, and under the force formed by the synchronous movement of the secondary peeling roller and the upper roller or the lower roller, the cell layer after peeling the glass layer moves toward the exit of the peeling channel; in addition, the power module drives the transmission unit and the peeling unit to move towards or away from each other, so as to drive the transmission channel and the peeling channel to connect or move away from each other, so that the peeling system can flexibly switch between the normal working state and the material jamming shutdown cleaning state.Therefore, compared with the prior art, the present invention, on the one hand, is based on the preheating channel and the formation of the heating area for the glass layer, so that the single-glass component is heated in sections during the transmission, and the preheated battery cell is easy to deform to flexibly adapt to the change of the transmission direction, and at the same time, the glue layer between the battery cell and the glass is gradually softened for easy peeling; on the other hand, by combining scraping and grinding, based on the single-glass component being transmitted from front to back, the single-glass component gradually moves from bottom to top and the glass layer is initially peeled by scraping, and then the remaining glass layer is completely removed by grinding, which greatly improves the efficiency and quality of glass peeling, avoids secondary adhesion, and effectively reduces the glass residue rate; in addition, based on the upper and lower rollers and The cooperation of the scraping module and the secondary stripping module can clear the accumulated glass fragments by moving the conveying unit away from the stripping unit, so as to quickly eliminate the jamming problem, and the operation is simple and convenient; thirdly, by controlling the thickness of the two parts in the stripping channel, it is ensured that the single-glass component enters the secondary stripping 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 of the battery layer can be completely removed after passing through the secondary stripping roller; fourthly, 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-contact and adhesion to the battery layer; fifthly, by setting a guide surface, the single-glass The probability of the component successfully entering between the upper roller and the secondary stripping roller; on the sixth aspect, by setting up a waste discharge channel, it is easy to discharge the glass fragments generated by scraping, and avoid the probability of material jamming caused by the accumulation of glass fragments;
