Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a single-container type single-glass photovoltaic component recycling device. Background Art

[0002] Photovoltaic modules are mainly divided into single-glass modules and double-glass modules. However, for the recycling of cells in single-glass modules (with frames), the general recycling process is as follows: module loading, wire cutting and junction box removal, frame removal, and glass removal. During the glass removal process, pre-processing and crushing are required, and then the glass layer is removed by various cutting methods such as scraping or grinding to complete the recycling of the desired cells.

[0003] However, for on-site recycling (meeting the requirements for trailer transportation), there are the following technical defects:

[0004] 1) The overall length of the above components is much longer than the length of a standard transport container. Therefore, two containers must be used to complete the loading. Therefore, during the on-site recycling process, not only the transportation cost cannot be effectively controlled, but also the on-site use is restricted by many factors, such as: site restrictions, unable to accommodate two containers at the same time or there is a high height difference between the two containers that cannot be assembled and adjusted, and the practicality is general;

[0005] 2) During the glass removal process, especially when entering the stripping equipment for stripping and removal, the component itself will inevitably deform, and most of the transmission is carried out by using transmission rollers moving in opposite directions. Therefore, during the stripping process, the probability of excessive stripping causing deformation or damage to the battery cell is high, and most of the battery cells cannot be output flat, that is, the processed battery cells are basically arc-shaped, which is obviously not conducive to the subsequent stacking and collection of battery cells. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved single-container type single-glass photovoltaic module recycling device.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A single-container type single-glass photovoltaic module recycling equipment, which includes a container, a loading device, a junction box removal device, and a glass removal device. In particular, each device is located in the same container. The junction box removal device includes a wire drawing, a wire cutting mechanism and a scraping mechanism located at the same junction box disassembly and assembly station; the glass removal device includes a pretreatment furnace for preheating photovoltaic modules, and a glass removal mechanism connected to the pretreatment furnace. The glass removal mechanism includes a frame with a feed inlet and a discharge port, a transmission unit and a cutting unit. The transmission unit includes a frame plate extending horizontally from the feed inlet to the discharge port, and an annular conveyor pressure belt installed above the frame plate and capable of being raised and lowered, wherein the annular conveyor pressure belt provides downward pressure and forward transmission power, and the photovoltaic modules and battery cells are respectively kept in contact with the frame plate and the annular conveyor pressure belt. A feed inlet and a discharge outlet; the cutting unit includes a plurality of cutting tools emerging from the top of the frame plate and arranged with the axis line vertically, and a power component for driving the plurality of cutting tools to rotate in the same direction and / or in the opposite direction, the plurality of cutting tools are divided into a plurality of rows in the transmission direction of the photovoltaic module, and the plurality of rows of cutting tools are relatively staggered and separated, wherein the plurality of rows are divided into at least a first cutting group and a second cutting group which successively cut with the glass and fully cover the entire width of the photovoltaic module, the first cutting group has at least two cutting tools, which are a grooving cutting group; the second cutting group has a number of cutting tools greater than or equal to that of the first cutting group, and are a sweeping cutting group.

[0009] Preferably, the junction box is removed by reeling, cutting and scraping in the direction of transmission of the photovoltaic module. That is, the space required for removing the junction box is simplified. Regardless of whether reeling or cutting is required, the function is to be used as a backup. The junction box can also be directly scraped to increase practicality (to meet the needs of removing junction boxes of different shapes).

[0010] According to a specific implementation and preferred aspect of the present invention, the number of cutting tools arranged in the first cutting group and the second cutting group from the feed port to the discharge port increases row by row. Here, based on the change in the number of tools, not only the cutting difficulty is reduced, but also the cutting quality is improved.

[0011] Preferably, the cutting area formed by the first cutting group is smaller than the cutting area formed by the second cutting group, and the cutting areas formed by each row of cutting tools are arranged from small to large based on the cutting sequence. Here, based on the change in the size of the cutting area of ​​the tool, especially the contact with the glass is also small at first and then large, which greatly reduces the difficulty of slotting and cutting, and the use of a gradually increasing cutting method reduces the damage to the tool itself.

[0012] In some specific embodiments, the cutting areas formed by the cutting tools in the same row are equal. Here, the cutting effect formed between the cutting tools in the same row is stable to reduce the cutting interference between the cutting tools in the same row.

[0013] According to another specific implementation and preferred aspect of the present invention, each cutting tool includes a tool holder, a tool head detachable from the tool holder, the tool holder includes a cone portion with a gradually decreasing outer diameter from top to bottom, and an external connection portion extending vertically downward from the bottom surface of the cone portion, wherein the external connection portion rotates relative to the bearing and the bearing holder through a bearing, and the tool head is a grinding disc or a saw disc, and the tool head in this example is formed with a cutting edge (i.e., a saw disc) from the circumference. Here, based on the strength formed by the cone portion, not only is it easy to disassemble and replace the tool head, but it also improves the cutting performance and service life of the tool.

[0014] Preferably, the power assembly includes a motor, a transmission wheel arranged on each of the external parts, and a transmission belt for connecting the motor to the transmission wheel, wherein there are at least two motors, there are multiple transmission belts, and the multiple transmission wheels rotate synchronously in the same direction or partially in the opposite direction. In short, the corresponding tool can be rotated and cut by the same or opposite direction rotation of the multiple transmission wheels.

[0015] According to another specific implementation and preferred aspect of the present invention, the glass removal device also includes a stripping roller arranged at the discharge end of the frame plate, and a driver for driving the stripping roller and the annular transmission pressure belt to move toward each other, wherein a portion of the roller surface of the stripping roller contacts the battery cell after the glass is cut to strip off the residual glass on the surface of the battery cell.

[0016] Preferably, the stripping roller includes a roller body and a plurality of roller pins distributed on the circumference of the roller body, wherein the roller pins are in contact with the surface of the cell to form stripping, and the roller body is adjustably mounted on the corresponding frame through elastic connectors from the axial ends. The elastic connector is adjusted and set to meet the actual needs to adjust the distance between the stripping roller and the annular conveyor belt to avoid damage to the cell; at the same time, the roller pins used are more conducive to the separation of the glass and the cell after stripping.

[0017] In some specific embodiments, the plurality of roller pins are divided into a plurality of roller pin groups, and the roller pins of each roller pin group extend radially along the roller body and are evenly spaced and distributed around the outer periphery of the roller body; further, the plurality of roller pin groups are aligned and distributed in the axial direction of the roller body. That is, the use of a stripping roller with roller pins similar to a hob shape can not only further cooperate with the stripping of residual glass, but also cooperate with the annular transmission pressure belt to form traction, reduce the probability of material jamming or blocking during glass removal, and further improve the flatness of the battery cell discharge. At the same time, each group of roller pins is aligned in the axial direction of the stripping roller. The stripping force formed by the rotation of the stripping roller remains in the same direction, which is more conducive to the forward transmission of the battery cell.

[0018] According to another specific implementation and preferred aspect of the present invention, the transmission unit also includes a lifting mechanism for driving the circular conveyor belt to move up and down, wherein the lifting mechanism includes a truss formed from both sides of the circular conveyor belt and located above the circular conveyor belt, a fixed seat installed on the frame, and a power device for driving the truss to move up and down relative to the fixed seat, wherein the power device is a telescopic rod or a power screw or a gear rack or a sprocket chain for linear motion. Here, the main purposes of setting the lifting mechanism are: 1. Adjusting the pressure and friction power formed by the circular conveyor belt to meet the cutting power requirements; 2. Facilitating the maintenance and maintenance of the stripping roller and the cutting tool.

[0019] According to another specific implementation and preferred aspect of the present invention, the glass removal device further includes a broken glass collection unit connected to the frame, the broken glass collection unit includes a guardrail that relatively closes or covers the end of the flattening channel and the end of the stripping roller, a collection hopper that gradually narrows from the bottom of the guardrail from top to bottom, and a broken glass conveyor belt located below the collection hopper, wherein the side wall of the collection hopper is inclined from top to bottom, and the cut broken glass slides down to the broken glass conveyor belt based on the side wall guidance. Under the push of the photovoltaic module, the broken glass falls into the collection hopper from the gap formed by the cutter, the stripping roller and the guardrail (similar to the collection of sawdust by sawing), and then the collection hopper collects and unloads the broken glass to the broken glass conveyor belt below, and finally the broken glass is conveyed out through the broken glass conveyor belt.

[0020] In addition, the loading device, junction box removal device, and glass removal device are arranged in sequence along the length of the container; and the sides and tail of the container can be flipped open, and the junction box and broken glass are unloaded from the sides of the container respectively; the cells are unloaded from the tail. The side wings and tail wings of the container are unfolded to facilitate the collection of disassembled parts. At the same time, the above-mentioned single-container single-glass photovoltaic module recycling equipment is suitable for the recycling of cells of frameless single-glass modules.

[0021] According to another specific implementation and preferred aspect of the present invention, the single-glass photovoltaic module recycling equipment also includes a frame removal device arranged in the container and between the junction box removal device and the glass removal device. In other words, this device can implement the cell recycling of framed single-glass modules. Of course, there is another mode. With this device, when the frame removal device is not working, the cell recycling of frameless single-glass modules can also be carried out. However, it can be selected according to actual needs to meet the cell recycling of photovoltaic modules under different working conditions and enhance the flexibility and practicality of recycling.

[0022] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] Based on the existing on-site recycling of single-glass components, the overall length formed by the configured components is much longer than the length of a standard transport container. Therefore, two containers must be used to complete the loading. Therefore, during the on-site recycling process, not only can the transportation cost not be effectively controlled, but it is also restricted by many factors during on-site use, such as: site limitations, inability to accommodate two containers at the same time or a high drop between the two containers that cannot be assembled and adjusted, and the practicality is general; then during the glass removal process, especially when entering the stripping equipment for stripping and removal, the component itself will inevitably deform, and most of the transmission is carried out by feeding with transmission rollers moving in opposite directions. Therefore, during the stripping process, the probability of excessive stripping causing deformation and causing deformation or damage to the battery cell is high, and most of the battery cells cannot be output flat, that is, the processed battery cells are basically arc-shaped, which is obviously not conducive to the later battery cell stacking and collection. The present invention cleverly solves the various deficiencies of the existing structure by overall design of the single-container single-glass photovoltaic component recycling equipment. After adopting the recycling equipment, firstly, the stacked photovoltaic module loading device is put into the loading device, and the single glass module is supplied piece by piece by the loading device, wherein the junction box faces upward; then, the junction box removal device is used to scrape off the junction box on the surface; finally, it first enters the pretreatment furnace for preheating, and the glass layer faces downward and passes out of the pretreatment furnace into the glass removal unit. At this time, the photovoltaic module is flattened by the flattening channel formed by the annular transmission pressing belt and the frame plate, and the glass layer is kept in contact with the frame plate, and the annular transmission pressing belt provides power for forward transmission, while the first cutting group and the second cutting group perform the groove cutting group and the sweeping cutting group backward, and the cell piece with the glass removed is kept in contact with the annular transmission pressing belt and the frame plate. The battery cells are output from the discharge port after being pressed and bonded with the piercing belt to complete the recovery of the battery cells. Therefore, on the one hand, the present invention is based on the loading device, the junction box removal device and the glass removal device arranged in the same container, that is, the on-site battery cell recovery of the frameless single-glass component is completed under the premise of effectively reducing the container restriction factor; on the other hand, under the same benchmark, the flat feeding of the photovoltaic component and the flat discharging of the battery cells are maintained, and the single-glass component after preheating is successively subjected to the grooving cutting group and the sweeping cutting group to remove the glass layer in a covering and pushing manner, which not only reduces the probability of battery cell breakage or damage, but also the formed glass peeling rate exceeds 98%.

Example 1

[0050] like Figures 1 to 14 As shown, the single-container type single-glass photovoltaic module recycling equipment of this embodiment includes a container 1, a loading device 2, a junction box removal device 3, and a glass removal device 4.

[0051] Specifically, the container 1 has a head, a middle part and a tail part, wherein the two opposite side wings of the head part can be flipped and unfolded around their own length direction, the side wings of the middle part can be flipped and unfolded around their own length direction, and the side wings and tail wing of the tail part can both be flipped and unfolded.

[0052] In some specific embodiments, the feeding device 2, the junction box removal device 3, and the glass removal device 4 are located in the same container 1, wherein the feeding device 2 is located at the head 1a, the junction box removal device 3 is located at the middle 1b, and the glass removal device 4 is located at the tail 1c. That is, the feeding device 2, the junction box removal device 3, and the glass removal device 4 are arranged in sequence along the length direction of the container 1; and the side and tail 1c of the container 1 can be flipped open, and the junction box and broken glass are unloaded from the side of the container 1 respectively; the battery cells are unloaded from the tail 1c. The side wings and tail wings of the container are unfolded to facilitate the collection of disassembled parts. At the same time, the above-mentioned single-container single-glass photovoltaic module recycling equipment is suitable for the recycling of battery cells of frameless single-glass modules.

[0053] In this example, the feeding device 2 adopts stacking feeding, and uses a robot to translate the photovoltaic modules piece by piece to the junction box removal device 3, while keeping the junction box of the photovoltaic module facing upward.

[0054] In this example, the junction box removal device 3 includes a wire drawing and wire cutting mechanism 30 and a scraping mechanism 31, and an XY axis lateral movement adjustment mechanism 32 located at the same junction box disassembly and assembly station, wherein the XY axis lateral movement adjustment mechanism 32 first adjusts the assembly in the XY axis coordinate system, and then the wire drawing and wire cutting mechanism 30 draws and cuts the wires, and then the scraping mechanism 31 scrapes the box body. In short, the wire drawing, wire cutting and scraping are performed in sequence along the transmission direction of the photovoltaic module to remove the junction box. That is, the space required for the removal of the junction box is simplified. Regardless of whether the wire drawing or wire cutting is required, its function is to be spare, and the junction box scraping can also be directly implemented to increase practicality (to meet the removal of junction boxes of different shapes). Specifically, the wire drawing and wire cutting mechanism 30 straightens the wires of the junction box (a comb with a combing line can be used to move horizontally to relatively straighten the body), and then cuts it close to the box body with scissors, and then scrapes the junction box away from the glass layer with a scraper.

[0055] In this example, the glass removal device 4 includes a pretreatment furnace 40 for preheating the photovoltaic modules, and a glass removal mechanism 41 connected to the pretreatment furnace 40, wherein the pretreatment furnace 40 can be heated to about 80~100° (which mainly serves the purpose of softening the glue layer and further facilitates the cutting of the glass), and the photovoltaic modules transmitted from the pretreatment furnace 40 are transferred from the glass layer downward to the glass removal mechanism 41; the glass removal mechanism 41 includes a frame 410 with a feed port m and a discharge port n, a transmission unit 411 and a cutting unit 412.

[0056] In some specific embodiments, the transmission unit 411 includes a frame plate a extending horizontally from the feed port m to the discharge port n, an annular conveyor belt b installed above the frame plate a and capable of being raised and lowered, and a lifting mechanism c for driving the annular conveyor belt to move up and down, wherein a flattening channel is formed between the frame plate a and the annular conveyor belt b, the photovoltaic module enters the flattening channel from the glass downward and is provided with downward pressure and forward transmission force by the annular conveyor belt, and the lifting mechanism c includes a truss c1 formed on both sides of the annular conveyor belt b and located above the annular conveyor belt b, a fixed seat c2 installed on the frame 410, and a power device c3 driving the truss c1 to move up and down relative to the fixed seat c2, wherein the power device c3 is a telescopic rod or a power lead screw or a gear rack or a sprocket chain for linear motion. Here, the main purposes of setting the lifting mechanism are: 1. Adjusting the pressure and friction power formed by the annular conveyor belt to meet the cutting power requirements; 2. Facilitating the maintenance and maintenance of the stripping roller and the cutting tool. In this example, a gear and rack transmission method is adopted, and a slide rail guide method is used to achieve up and down lifting adjustment.

[0057] Furthermore, the power motor b1 of the ring-shaped transmission pressure belt b is also installed on the truss c1. Therefore, the components located above the frame a (ring-shaped transmission pressure belt, lifting mechanism, power motor, etc.) can increase the positive pressure, thereby greatly reducing the probability of component deviation during cutting.

[0058] The cutting unit 412 is located at the exit of the flattening channel and includes a plurality of cutting tools d protruding from the top of the frame a and arranged with the axis line vertically, a power assembly e for driving the plurality of cutting tools d to rotate in the same direction and / or in the opposite direction, a stripping roller f arranged at the discharge port of the frame a and below the annular conveyor belt b, and a driver g for driving the stripping roller f and the annular conveyor belt to move in opposite directions, wherein each cutting tool d forms a cutting surface in the circumferential direction and forms a cutting area on the width of the corresponding flattening channel; the protruding length of each cutting tool d is equal to the thickness of the glass layer to be removed.

[0059] In some specific embodiments, multiple cutting tools d are divided into multiple rows in the transmission direction of the photovoltaic module, and the multiple rows of cutting tools are relatively staggered and separated, wherein the multiple rows are at least divided into a first cutting group and a second cutting group that successively form cutting with the glass and fully cover the entire width of the photovoltaic module, the number of cutting tools in the first cutting group is at least two, and it is a slotting cutting group; the number of cutting tools in the second cutting group is greater than or equal to the number of cutting tools in the first cutting group, and it is a sweeping cutting group. In this example, the number of cutting tools arranged from the feed port to the discharge port of the first cutting group and the second cutting group increases row by row. Here, based on the change in the number of tools, not only the cutting difficulty is reduced, but also the cutting quality is improved. The cutting area formed by the first cutting group is smaller than the cutting area formed by the second cutting group, and the cutting area formed by each row of cutting tools is arranged from small to large based on the order of cutting. Here, based on the change in the size of the cutting area of ​​the tool, especially the contact with the glass is also small first and then large, the difficulty of slotting cutting is greatly reduced, and the use of a gradually increasing cutting method will cause much less damage to the tool itself. The cutting areas formed by the cutting tools in the same row are equal. Here, the cutting effect formed between the cutting tools in the same row is stable, so as to reduce the cutting interference between the cutting tools in the same row.

[0060] In this example, there are five cutting tools d, and the five cutting tools d are arranged side by side and staggered in the length direction of the flattening channel, and the cutting areas are complementary and / or overlapped to cover the width of the photovoltaic module entering the flattening channel. That is, the cutting tools d form two rows from the inlet to the outlet, two in the front row and three in the back row (a total of 5). Specifically, the number of cutting tools in the front row plus one is equal to the number of cutting tools in the back row, wherein the glass layer is removed in a high-speed and efficient mode by the front row slotting cutting and the back row horizontal push cutting. In this example, the cutting areas formed by the cutting tools d are of different sizes, the two cutting tools in the front row have a small outer diameter, the three cutting tools in the back row have a large outer diameter, and the cutting areas formed from the inlet to the outlet are arranged from small to large. Based on the cutting tools with different outer diameters, the smaller the cutting tools, the easier it is to form open-circuit cutting. As for the arrangement of the cutting tools from small to large, the difficulty of removing the glass layer will be greatly reduced, and the differentiated area cutting is carried out to achieve comprehensive and sequential cutting to achieve the rear row horizontal push cutting. Furthermore, the cutting areas formed by the cutting tools d in each row are equal, that is, each row of cutting tools d forms equal cutting to avoid cutting interference between cutting tools d in the same row; at the same time, each row of cutting tools d is symmetrically arranged about the center line of the flattening channel, and some cutting tools d are located on the center line of the flattening channel. Therefore, the layout of the tools is completely based on the center line layout of the flattening channel, and in order to improve the cutting quality, a centering guide joint is also provided at the feed port.

[0061] In some specific embodiments, each cutting tool d includes a tool seat d1, a tool head d2 having a cutting surface and detachable from the tool seat d1, the tool seat d1 includes a cone portion d10 with a gradually decreasing outer diameter from top to bottom, and an external connection portion d11 vertically extending downward from the bottom surface of the cone portion d10, wherein the external connection portion d11 rotates relative to the bearing seat through a bearing. Here, based on the strength formed by the cone portion d10, not only is it convenient to disassemble and replace the tool head d2, but also the cutting performance and service life of the tool are improved.

[0062] In some specific embodiments, the power assembly e includes a transmission wheel e1 installed on each external portion d11, a motor e2, and a transmission belt e3 for connecting the motor e2 and the transmission wheel e1, wherein there is at least one motor e2, and multiple transmission wheels e1 are connected to the corresponding motor e2 through the transmission belt e3. In short, the rotation cutting of the corresponding tool is achieved by rotating the multiple transmission wheels e1 in the same direction or in the opposite direction. In this example, two motors e2 are used to drive the five transmission wheels e1 in two rows (corresponding to five cutting tools d), one of which is connected to the front row transmission wheel e1 and the rear row transmission wheels e1 through the transmission belt e3; the other motor e2 is connected to the remaining front and rear transmission wheels e1. As for the transmission direction, the same direction is used in this example (it can also be that one motor e2 drives the front row two transmission wheels e1 to move in the same direction, and the other motor e2 drives the rear row three transmission wheels e1 to move in the same direction, and the rotation directions of the front row and the rear row are opposite).

[0063] In some specific embodiments, part of the roller surface of the stripping roller f contacts the battery cell after the glass is cut to strip the residual glass on the surface of the battery cell. The stripping roller f includes a roller body f1 and a plurality of roller pins f2 distributed on the circumference of the roller body f1, wherein the roller pins f2 are in contact with the surface of the battery cell to form stripping, and the roller body f1 is adjustably mounted on the corresponding frame through elastic connectors k from the axial ends. The adjustment setting is based on the elastic connector to meet the actual needs to adjust the distance between the stripping roller and the annular conveyor belt to avoid damage to the battery cell; at the same time, the roller pins used are more conducive to the separation of the glass and the battery cell after stripping. In this example, the plurality of roller pins f2 are divided into a plurality of roller pin groups, and the roller pins f2 of each roller pin group extend radially along the roller body f1 and are evenly spaced around the outer periphery of the roller body; further, the plurality of roller pin groups are aligned and distributed in the axial direction of the roller body f1. That is, the use of a stripping roller with roller pins similar to a hob shape can not only further cooperate with the stripping of residual glass, but also cooperate with the annular transmission pressure belt to form traction, reduce the probability of glass removal jamming or blocking, and further improve the flatness of the battery cell discharge. At the same time, each group of roller pins is aligned in the axial direction of the stripping roller. The stripping force generated by the rotation of the stripping roller remains in the same direction, which is more conducive to the forward transmission of the battery cell.

[0064] In addition, the glass removal mechanism 41 also includes a broken glass collection unit 413 connected to the frame a, and the broken glass collection unit 413 includes a guardrail h that relatively closes or covers the end of the flattening channel and the end of the stripping roller f, a collecting hopper i that gradually narrows from the bottom of the guardrail h from top to bottom, and a broken glass conveyor belt j located below the collecting hopper i, wherein the side wall of the collecting hopper i is inclined from top to bottom, and the cut broken glass slides to the broken glass conveyor belt j based on the side wall guidance.

However, it can be selected according to actual needs to meet the cell recycling of photovoltaic modules under different working conditions and enhance the flexibility and practicality of recycling. As for the structure of the frame removal device 5, please refer to the frame removal device in CN117259386B, which will not be elaborated here.

[0068] That is, the implementation process of this embodiment is as follows:

[0069] First, the stacked photovoltaic module loading device is used to supply single-glass modules piece by piece, with the junction box facing upward; then, the junction box removal device is used to scrape off the junction box on the surface, and the junction box is discharged from the side of the container; then, it is sent to the frame removal device to remove the surrounding frames in pairs simultaneously, and the frames are discharged from the side of the container at the same time; finally, it enters the pretreatment furnace for preheating, and the glass layer is transferred from the pretreatment furnace to the glass removal unit with the glass layer facing downward. At this time, the flattening channel formed by the annular transmission pressure belt and the frame plate will enter the photovoltaic module The glass is flattened to keep the glass layer in contact with the frame plate, and the annular transmission pressure belt provides power for forward transmission. At the same time, the first cutting group and the second cutting group perform grooving cutting group and sweeping cutting group backward, and the battery cell with removed glass is kept in contact with the annular penetration and pressure belt and output from the discharge port.

At the same time, the probability of glass jamming or blocking during removal is also reduced, further improving the flatness of the cell output; the third aspect simplifies the space required for junction box removal. Regardless of whether wire drawing or wire cutting is required, its function is standby, and the junction box can also be directly removed to increase practicality (to meet the removal of junction boxes of different shapes); the fourth aspect is based on the change in the number of tools in the first cutting group and the second cutting group, which not only reduces the cutting difficulty, but also improves the cutting quality. At the same time, based on the change in the size of the cutting area of ​​the tool, especially the contact with the glass is small at first and then large, which greatly reduces the difficulty of slotting and cutting, and adopts a gradually increasing cutting method to improve the self- The damage to the body is much smaller, and then the cutting effect formed between the cutting tools in the same row is stable, so as to reduce the cutting interference between the cutting tools in the same row; the fifth aspect is based on the strength formed by the frustum, which is not only convenient for the disassembly and replacement of the cutter head, but also improves the cutting performance and service life of the tool; at the same time, through the same or reverse rotation of multiple transmission wheels, the corresponding tool can be rotated to cut; the sixth aspect is based on the elastic connection to adjust the setting to meet the actual needs of the distance between the stripping roller and the annular conveyor belt to avoid damage to the battery cell; at the same time, the roller nails used are more conducive to the separation of the glass and the battery cell after stripping. In addition, the roller nail group adopts a stripping roller with roller nails similar to the hob shape, which can not only further cooperate with the stripping of the residual glass, Moreover, it can cooperate with the annular transmission pressure belt to form traction, reduce the probability of material jamming or blocking during glass removal, and further improve the flatness of the battery cell discharge. At the same time, each group of roller nails is aligned in the axial direction of the stripping roller, and the stripping force formed by the rotation of the stripping roller remains in the same direction, which is more conducive to the forward transmission of the battery cell; the seventh aspect is based on the contact area formed by the annular transmission pressure belt (in this case, the annular transmission pressure belt is a rubber belt, and the pressure formed is sufficient to avoid left and right displacement during cutting, and the pressure formed exceeds 400N), so that the pressure and power provided by it, as well as the power generated by exploitation, constitute power output, avoid material jamming or blocking, and at the same time, based on equal cutting, reduce the damage rate caused by battery cell cutting;In addition, the main purposes of setting up the lifting mechanism are: 1. Adjusting the pressure and friction power formed by the annular conveyor belt to meet the cutting power requirements; 2. Facilitating the maintenance and maintenance of the stripping roller and cutting tool; on the eighth aspect, under the push of the photovoltaic module, the broken glass falls into the collection hopper from the gap formed by the tool, stripping roller and railing (similar to the collection of sawdust by sawing), and then the collection hopper collects and unloads the broken glass to the broken glass conveyor belt below, and finally transmits the broken glass through the broken glass conveyor belt; on the ninth aspect, whether it is a framed or frameless single-glass photovoltaic module recycling equipment, it can be recycled using the equipment of Example 2. Of course, it is clear that it is a frameless module, and the actual The equipment of Example 1 can be recycled, so that it can be selected based on actual conditions to meet the recycling of cells of single glass components on site in a single container, enhancing the flexibility and practicality of recycling; in the tenth aspect, the glass removal device of this embodiment is used, and its final stripping and removal rate exceeds 98%, and it also solves the problem of transmission and stacking of photovoltaic components and recycled cells. In addition, based on the overall layout of the shape, it not only solves the problem of space limitation, but also facilitates mobile site recycling; at the same time, the deformation of the component itself will not affect the subsequent stripping (especially quantitative cutting), which will cause damage to the cell; similarly, no pre-crushing is required, further reducing the deformation or damage rate of the cell. ;
