Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic module recycling, and in particular relates to a photovoltaic module backboard stripping device. Background Art

[0002] Photovoltaic modules are used in many fields. During use, they will continue to age due to environmental erosion and ultraviolet radiation, causing the battery efficiency to gradually decay until it is scrapped. Wasted photovoltaic modules still contain a large amount of reusable components such as tempered glass, crystalline silicon, copper, and aluminum. Therefore, how to properly dispose of waste photovoltaic modules is one of the keys to avoiding waste of resources and reducing environmental pollution.

[0003] Existing photovoltaic modules generally peel off the back sheet so that the cover glass and crystalline silicon cells can be separated from the back sheet, thereby achieving subsequent classified recycling. However, the back sheet usually needs to be peeled off manually, which requires a huge manpower cost and the speed of peeling is slow. At the same time, it is difficult to ensure the quality control of the subsequent results through manual peeling operations. It is very likely that the low quality of the peeling operation will result in too few components being recycled in the end, which will have a great impact on subsequent recycling and easily make the overall work of recycling photovoltaic modules unprofitable. In addition, there is also the risk of being scratched by the cover glass during manual operation, which will cause the peeling work to be suspended while there is danger.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Reference Figure 1The present invention provides a photovoltaic module back sheet peeling device, comprising: a conveying part 100 and a peeling part 200. A mobile platform is provided on the conveying part 100, and the photovoltaic module can be transported to a preset position through the mobile platform. The peeling part 200 is movably arranged toward the mobile platform. A first cutting component 230 is movably provided on one side of the peeling part 200, and the first cutting component 230 can cut one set of opposite two sides of the photovoltaic module. A second cutting component 240 is movably provided on the other side of the peeling part 200, and the second cutting component 240 can cut another set of opposite two sides of the photovoltaic module. A shovel roll clamping component 250 is movably provided on the side of the peeling part 200 close to the mobile platform, and a clamping cavity is provided on the shovel roll clamping component 250. The side of the shovel roll clamping component 250 close to the mobile platform can shovel up the back sheet of the photovoltaic module, and insert one side of the back sheet into the clamping cavity. The clamping cavity can shrink to clamp the side of the back sheet inserted into the clamping cavity in the clamping cavity.

[0055] Specifically, a mobile platform is provided on the upper surface of the conveying portion 100, and the waste photovoltaic components can be transported to a preset position on the mobile platform through the mobile platform. The stripping portion 200 is provided above the upper surface of the conveying portion 100, so that the working end of the stripping portion 200 can be set toward the mobile platform, wherein the stripping portion 200 is movably provided, and the stripping portion 200 can be moved to above the preset position through the movement of the stripping portion 200, so that the working end of the stripping portion 200 can be set directly facing the photovoltaic component on the mobile platform. The first cutting assembly 230 is arranged on one side of the peeling part 200, the second cutting assembly 240 is arranged on the other side of the peeling part 200, and the shoveling roll clamping assembly 250 is arranged on the side of the peeling part 200 close to the mobile platform. The first cutting assembly 230, the second cutting assembly 240 and the shoveling roll clamping assembly 250 are all arranged toward the mobile platform, so that the first cutting assembly 230, the second cutting assembly 240 and the shoveling roll clamping assembly 250 cooperate with each other to form the working end of the peeling part 200, and a clamping cavity is arranged in the shoveling roll clamping assembly 250. Among them, the first cutting component 230 can be used to cut the two relatively set side edges of one group of photovoltaic components, and the second cutting component 240 can be used to cut the other two relatively set side edges of the photovoltaic component. The photovoltaic components with all four sides cut will expose a notch for insertion on at least one side of the back panel of the photovoltaic component, and the side of the shoveling and rolling clamping component 250 close to the movable platform can be inserted into the notch exposed by one side of the back panel. As the peeling part 200 moves, the shoveling and rolling clamping component 250 can shovel up the side of the back panel exposed by the notch, and the shoveled side of the back panel can continue to be inserted into the clamping cavity of the shoveling and rolling clamping component 250. Under the contraction of the clamping cavity, the spacing of the inner walls of the clamping cavity will be reduced, so that one side of the back panel inserted in the clamping cavity can be clamped and pressed, and as the peeling part 200 continues to move, the back panel can be torn off as a whole. It replaces the original manual operation method, while ensuring the safety of operation, reducing the required manpower cost, increasing the backplane peeling speed, and at the same time ensuring the quality of backplane peeling, so that there are more recyclable components after backplane peeling, avoiding the impact on subsequent recycling and greatly improving the efficiency of backplane peeling.

[0056] In some specific embodiments of the present invention, referring to Figure 2The conveying part 100 includes: a roller 120, a first blocking assembly 130 and a second blocking assembly 140. There are multiple rollers 120, and the multiple rollers 120 are arranged in sequence and spaced apart, and the multiple rollers 120 are rotatably connected by a chain, so that the multiple rollers 120 form a mobile platform. The first blocking assembly 130 is arranged on one side of the arrangement direction of the multiple rollers 120, and the first blocking assembly 130 can block the movement of the photovoltaic assembly. The second blocking assembly 140 is respectively arranged between each two adjacent rollers 120, and the second blocking assembly 140 can limit the moving direction of the photovoltaic assembly.

[0057] Specifically, two horizontal beams 110 are symmetrically arranged, and a plurality of rollers 120 are arranged between the two horizontal beams 110 in sequence, and the two ends of the rollers 120 are respectively rotatably connected to the two horizontal beams 110, so that a mobile platform is formed by the plurality of rollers 120. A first rotating motor 111 is arranged at one end of one of the horizontal beams 110, and a chain is meshedly arranged at the output end of the first rotating motor 111, and the chain is meshedly connected with the plurality of rollers 120 in sequence along the arrangement direction of the plurality of rollers 120, so that the chain can be driven by the first rotating motor 111 to drive the plurality of rollers 120 to rotate simultaneously, so that the photovoltaic components arriving on the mobile platform can be transported and moved along the arrangement direction of the plurality of rollers 120 under the rotation of the plurality of rollers 120. The first blocking assembly 130 is arranged between the symmetrical ends of the two cross beams 110, so that the first blocking assembly 130 can be located on one side of the arrangement direction of the plurality of rollers 120. When the photovoltaic assembly is conveyed and moved along the arrangement direction of the plurality of rollers 120, the first blocking assembly 130 can abut against one end of the photovoltaic assembly, thereby blocking the photovoltaic assembly from continuing to move. The second blocking assembly 140 is arranged between the intervals of each two adjacent rollers 120 of the plurality of rollers 120. When the photovoltaic assembly is conveyed, the second blocking assembly 140 can abut against one side of the photovoltaic assembly, thereby preventing the photovoltaic assembly from shaking left and right along the axial direction of the rollers 120 on the mobile platform, thereby limiting the moving direction of the photovoltaic assembly. Through the mutual cooperation of the first blocking assembly 130 and the second blocking assembly 140, the photovoltaic assembly can be limited to be conveyed to a preset position and the photovoltaic assembly can be limited, thereby facilitating the subsequent peeling of the back sheet.

[0058] Furthermore, the first blocking assembly 130 includes: a first lifting motor 131 and a first baffle 132. There are two first lifting motors 131, and the two first lifting motors 131 are respectively arranged at one end of the two beams 110, and the two first lifting motors 131 are symmetrically arranged. The two ends of the first baffle 132 are respectively connected to the lifting ends of the two first lifting motors 131, and the first baffle 132 can be driven to move up and down by the two first lifting motors 131. When it is necessary to block the movement of the photovoltaic assembly, the two first lifting motors 131 jointly drive the first baffle 132 to rise, so that the horizontal height of the first baffle 132 is higher than the horizontal height of the mobile platform or the beam 110, and the rising first baffle 132 can abut against one side of the photovoltaic assembly, thereby blocking the movement of the photovoltaic assembly.

[0059] Further, the second blocking assembly 140 includes: a second rotating motor 141 and a second baffle 142. A first lead screw 143 is provided under the rotating frame of the plurality of rollers 120, and the first lead screw 143 is arranged along the axial direction of the rollers 120. The second rotating motor 141 is arranged at the bottom of one of the cross beams 110, and the output end of the second rotating motor 141 is connected to one end of the lead screw, so that the first lead screw 143 can be driven to rotate by the second rotating motor 141. A plurality of grooves are sequentially arranged at intervals on one side of the second baffle 142 along the arrangement direction of the plurality of rollers 120, and the plurality of grooves are arranged one-to-one with the plurality of rollers 120, so that the plurality of rollers 120 can be embedded in the corresponding grooves at the same time, and the depth dimension of the groove is greater than the diameter of the roller 120. When the plurality of rollers 120 are embedded in the corresponding grooves at the same time, the horizontal height of the top of the second baffle 142 between each two adjacent grooves is higher than the horizontal height of the roller 120, so that it can abut against one side of the photovoltaic assembly, thereby limiting the moving direction of the photovoltaic assembly. Among them, the side of the second baffle 142 away from the roller 120 is rotatably connected to the outer peripheral thread of the first screw 143, so that the second baffle 142 can be driven to move axially along the roller 120 through the rotation of the first screw 143. The position of the second baffle 142 can be adjusted according to actual needs, so as to transport the photovoltaic assembly to a specific preset position.

[0060] Furthermore, a first guide rail 144 is provided below the plurality of rollers 120, the first guide rail 144 is arranged in parallel with the first lead screw 143, and the second baffle 142 is slidably connected to the first guide rail 144. The first guide rail 144 can ensure smooth movement of the second baffle 142.

[0061] Furthermore, there are two first guide rails 144 symmetrically disposed at two ends of the second baffle 142 , and the movement stability of the second baffle 142 can be further improved by the two first guide rails 144 .

[0062] Furthermore, there are two second baffles 142, and the two second baffles 142 are symmetrically arranged. The thread setting directions between the two ends of the first screw 143 are opposite, one of the second baffles 142 is connected to the forward thread of the first screw 143, and the other second baffle 142 is connected to the reverse thread of the first screw 143, so that the two second baffles 142 can be driven to move toward or in the opposite direction through the rotation of the first screw 143, and the two second baffles 142 can respectively abut against the opposite side edges of the photovoltaic component, thereby limiting the reverse direction of the photovoltaic component being transmitted, ensuring the position accuracy of the photovoltaic component being transmitted, and at the same time, when the photovoltaic component is transmitted to the preset position, the two second baffles 142 can clamp the photovoltaic component, thereby fixing the setting position of the photovoltaic component, avoiding the shaking of the photovoltaic component during cutting, and ensuring the cutting accuracy.

[0063] It should be noted that, in general, the first baffle 132 is used to abut against one side of the photovoltaic assembly in the length direction, and the two second baffles 142 are respectively abutted against the two side edges of the photovoltaic assembly in the width direction. That is, when the photovoltaic assembly is conveyed to the preset position, the length direction of the photovoltaic assembly is the same as the arrangement direction of the plurality of rollers 120, and the width direction of the photovoltaic assembly is the same as the axial direction of the roller 120, and is located in the middle of the roller 120.

[0064] In some specific embodiments of the present invention, referring to Figure 1 The stripping unit 200 includes a track 210 and a frame 220. The track 210 is mounted above the plurality of rollers 120 along the arrangement direction of the plurality of rollers 120. The frame 220 is movably disposed on the track 210. The first cutting assembly 230 is movably disposed on one side of the frame 220. The second cutting assembly 240 is movably disposed on the other side of the frame 220. The shovel roll clamping assembly 250 is movably disposed in the middle of the frame 220.

[0065] Specifically, there are two tracks 210, which are symmetrically arranged above the mobile platform, and the tracks 210 are arranged along the arrangement direction of the multiple rollers 120. The two ends of the frame 220 in the body length direction are respectively provided with third rotating motors 223, and the output ends of the two third rotating motors 223 are respectively engaged and connected with the two tracks 210 through gears, so that the frame 220 can be driven to move along the arrangement direction of the multiple rollers 120 on the two tracks 210 through the two third rotating motors 223. The first cutting assembly 230 is movably arranged on one side of the frame 220 in the body width direction, and the second cutting assembly 240 is movably arranged on the other side of the frame 220 in the body width direction. The shovel roll clamping assembly 250 is movably arranged in the middle of the frame 220, that is, between the first cutting assembly 230 and the second cutting assembly 240. By moving the frame 220 along the arrangement direction of the multiple rollers 120 on the two rails 210, the setting position of the frame 220 relative to the photovoltaic component conveyed to the preset position can be changed, so that the first cutting component 230, the second cutting component 240 and the shovel roll clamping component 250 can be aligned with specific parts of the photovoltaic component according to corresponding needs for cutting and peeling.

[0066] Further, refer to Figure 3 The frame 220 includes: a first frame 221 and a second frame 222. The first frame 221 is plate-shaped and is arranged horizontally. Two third rotary motors 223 are symmetrically arranged on the upper surfaces of both ends of the first frame 221 in the body length direction. The output end of the third rotary motor 223 is arranged through the first frame 221 to the lower surface of the first frame 221 and is meshed and connected with the corresponding track 210 through a gear. There are two second frames 222, which are arranged vertically. The two ends of the second frames 222 in the body length direction are arranged along the body length direction of the first frame 221. The two second frames 222 are symmetrically arranged on the lower surface of the first frame 221. One side of the second frame 222 in the body width direction is fixedly connected to the lower surface of the first frame 221, so that the space below the first frame 221 can be divided into three equal parts by the two second frames 222. One of the second frames 222 and the first frame 221 is enclosed to form a space for installing the first cutting assembly 230, the other second frame 222 and the first frame 221 is enclosed to form a space for installing the second cutting assembly 240, and the two second frames 222 and the first frame 221 are enclosed to form a space for installing the shovel roll clamping assembly 250. It is convenient for installation and avoids mutual influence between the first cutting assembly 230, the second cutting assembly 240 and the shovel roll clamping assembly 250.

[0067] It should be noted that the length direction of the first frame 221 and the length direction of the second frame 222 are the same as the axial direction of the drum 120 .

[0068] In some specific embodiments of the present invention, referring to Figure 3The first cutting assembly 230 includes: a first moving assembly 231, a first lifting assembly 232 and a first cutter 233.

When it is necessary to cut the photovoltaic module through the first cutting assembly 230, the first frame 221 is used to drive the first cutting assembly 230 to move, so that the first cutter 233 is aligned with one side of the body length direction of the photovoltaic module, and the first lifting assembly 232 is used to drive the first cutter 233 close to the photovoltaic module until the cutting side of the first cutter 233 abuts against the photovoltaic module, and then the first moving assembly 231 drives the first lifting assembly 232 and the first cutter 233 to move along the body width direction of the photovoltaic module, so that the photovoltaic module is cut by moving the cutting side of the first cutter 233, and after cutting, the first lifting assembly 232 is used to drive the first cutter 233 away from the photovoltaic module. At the same time, photovoltaic modules of different length and width specifications can also be cut.

The first moving seat 2313 is threadedly rotatably connected to the second lead screw 2312, and the rotation of the second lead screw 2312 can drive the first moving seat 2313 to move along the body length direction of the second frame 222.

[0070] Furthermore, a second guide rail 2314 is provided on the second frame 222 corresponding to the second lead screw 2312 along the length direction of the second frame 222 , and the first movable seat 2313 is also slidably connected to the second guide rail 2314 , thereby ensuring movement stability.

The first cutter 233 is arranged at the bottom of the first lifting seat 2322, and the lifting and lowering of the first lifting seat 2322 can drive the first cutter 233 to move closer to or away from the photovoltaic module placed on the mobile platform.

[0072] In some specific embodiments of the present invention, referring to Figure 4 The second cutting assembly 240 includes: a second moving assembly 241, a second lifting assembly 242, and a second cutting knife 243.

[0073] Specifically, the second moving assembly 241 is disposed in a space enclosed by another second frame 222 and the first frame 221, and the second lifting assembly 242 is disposed on the second moving assembly 241. The second lifting assembly 242 can be driven to move along the length direction of the second frame 222, i.e., the axial direction of the roller 120, through the second moving assembly 241. The second cutter 243 is disposed on the second lifting assembly 242 along the arrangement direction of the plurality of rollers 120, and the second lifting assembly 242 can drive the second cutter 243 to move up and down along the width direction of the second frame 222, i.e., to move closer to or away from the roller 120. When the photovoltaic module needs to be cut by the second cutting assembly 240, the second cutting assembly 240 is first driven to move by the first frame 221, so that the second cutter 243 is located at one end in the body length direction of the photovoltaic module, and then the second moving assembly 241 drives the second lifting assembly 242 and the second cutter 243 to move, so that the second cutter 243 is aligned with one side in the body width direction of the photovoltaic module, and then the second lifting assembly 242 drives the second cutter 243 close to the photovoltaic module until the cutting side of the second cutter 243 abuts against the photovoltaic module, and then the movement of the first frame 221 drives the second cutter 243 to move along the body length direction of the photovoltaic module, so that the photovoltaic module is cut by the movement of the second cutter 243, and after cutting, the second lifting assembly 242 drives the second cutter 243 away from the photovoltaic module. At the same time, photovoltaic modules of different length and width specifications can also be cut.

[0074] Further, the second moving assembly 241 includes: a fifth rotating motor 2411 and a second moving seat 2413. The third lead screw 2412 is rotatably arranged in the space enclosed by the other second frame 222 and the first frame 221, and the third lead screw 2412 is arranged along the body length direction of the second frame 222. The fifth rotating motor 2411 is arranged on the first frame 221, and the output end of the fifth rotating motor 2411 is connected to the third lead screw 2412 through a transmission belt, and the fifth rotating motor 2411 can drive the third lead screw 2412 to rotate. The second moving seat 2413 is threadedly rotatably connected to the third lead screw 2412, and the rotation of the third lead screw 2412 can drive the second moving seat 2413 to move along the body length direction of the second frame 222, so that the second cutter 243 can be aligned with one side of the photovoltaic module in the body width direction to ensure the accuracy of cutting.

[0075] Furthermore, a third guide rail 2414 is provided on the second frame 222 corresponding to the third lead screw 2412 along the length direction of the second frame 222 , and the second movable seat 2413 is also slidably connected to the third guide rail 2414 , thereby ensuring movement stability.

[0076] Furthermore, the second lifting assembly 242 includes: a third lifting motor 2421 and a second lifting seat 2422. The third lifting motor 2421 is fixedly arranged on the second moving seat 2413, and the second lifting seat 2422 is connected to the output end of the third lifting motor 2421. The third lifting motor 2421 can drive the second lifting seat 2422 to move up and down along the width direction of the second frame 222, that is, to move closer to or away from the drum 120. The second cutter 243 is arranged at the bottom of the second lifting seat 2422. The lifting and lowering of the second lifting seat 2422 can drive the second cutter 243 to move closer to or away from the photovoltaic assembly placed on the mobile platform.

[0077] In some specific embodiments of the present invention, referring to Figure 4 There are two second lifting assemblies 242, and the two second lifting assemblies 242 are symmetrically arranged on the second moving assembly 241. There are two second cutters 243, and the two second cutters 243 are arranged in a one-to-one correspondence with the two second lifting assemblies 242. The second moving assembly 241 can drive the two second lifting assemblies 242 to move closer to or away from each other. Specifically, the threads at both ends of the third lead screw 2412 are arranged in reverse, there are two second moving seats 2413, and the two second moving seats 2413 are symmetrically arranged at both ends of the third lead screw 2412, and the two third lifting motors 2421, the two second lifting seats 2422 and the two cutters are arranged in sequence corresponding to the two second moving seats 2413. When the third screw 2412 rotates, it can drive the two second movable seats 2413 to respectively drive the two second cutting knives 243 to move toward or oppositely, so that by adjusting the distance between the two second cutting knives 243, the two second cutting knives 243 can be aligned with the two side edges in the width direction of the photovoltaic component respectively. As the first frame 221 moves, the two side edges in the width direction of the photovoltaic component can be cut simultaneously by the two second cutting knives 243, thereby improving the cutting efficiency.

[0078] It should be noted that after the cutting of the two side edges of the photovoltaic module in the width direction is completed, the first frame 221 is moved again, and the other side edge of the photovoltaic module in the length direction is cut by the first cutting knife 233 .

[0079] In some specific embodiments of the present invention, referring to Figure 5The shovel roll clamping assembly 250 includes: a housing 251, a third lifting assembly 254 and a fourth lifting assembly 255. A pressure shovel 252 is provided on the housing 251. The housing 251 is provided at the middle of the bottom side of the frame 220 through the third lifting assembly 254, and the third lifting assembly 254 can drive the housing 251 close to or away from the roller 120. One end of the fourth lifting assembly 255 is fixedly penetrated through the housing 251 and connected to a pressing plate 253, which is located above the pressing shovel 252, and the fourth lifting assembly 255 can drive the pressing plate 253 close to or away from the pressing shovel 252. The pressing plate 253 and the pressing shovel 252 enclose a clamping cavity.

[0080] Specifically, the two ends of the shell 251 in the body length direction are arranged in the space enclosed by the two second frames 222 and the first frame 221 along the body length direction of the second frame 222. The interior of the shell 251 is hollow, and the bottom and one side of the shell 251 are open structures. The pressure shovel 252 is arranged at the bottom of the shell 251 along the body length direction of the shell 251. Under the action of the pressure shovel 252, the force area when pulling the back plate can be increased to avoid the back plate from being cracked. The top of the shell 251 is connected to the first frame 221 through the third lifting component 254. The third lifting component 254 can drive the shell 251 and the pressure shovel 252 to be lifted and lowered along the body width direction of the second frame 222, that is, close to or away from the drum 120. The pressing plate 253 is arranged inside the shell 251 along the length direction of the shell 251 and is located above the pressing shovel 252. One end of the fourth lifting assembly 255 is fixedly penetrated through the top of the shell 251 and connected to the pressing plate 253. The pressing plate 253 can be driven to move up and down along the width direction of the second frame 222, that is, close to or away from the pressing shovel 252, through the fourth lifting assembly 255. The upper surface of the pressing shovel 252 and the lower surface of the pressing plate 253 are combined to form a clamping cavity. After the four sides of the photovoltaic module are cut, the internal copper solder strip of the photovoltaic module is cut off, which will cause the back plate of one side of the photovoltaic module in the length direction to be slightly rolled up, thereby forming a gap for the pressing shovel 252 to be inserted. When the first frame 221 is moved, the pressure shovel 252 is aligned with the slightly rolled-up position of the backboard, and then the shell 251 and the pressure shovel 252 are driven to approach the slightly rolled-up position of the backboard by the third lifting component 254. Then, the pressure shovel 252 is inserted into the gap formed by the slightly rolled-up backboard through the movement of the first frame 221, so that one side of the backboard is inserted into the clamping cavity surrounded by the pressing plate 253 and the pressure shovel 252, and then the pressure shovel 252 is driven to rise by the third lifting component 254. At the same time, the fourth lifting component 255 drives the pressing plate 253 to approach the pressure shovel 252 until the side of the backboard inserted into the clamping cavity is clamped between the pressing plate 253 and the pressure shovel 252, and then the pressing plate 253 and the pressure shovel 252 are driven to rise by the third lifting component 254, thereby lifting one side of the backboard. Finally, the backboard can be torn off by moving the first frame 221. It replaces the original manual operation mode, while ensuring the safety of operation, reducing the labor cost required, and can shorten the time of the whole process of back sheet peeling to less than 2 minutes, greatly improving the speed of back sheet peeling. At the same time, it ensures the quality of back sheet peeling, so that there are more recyclable components after back sheet peeling, avoiding the impact on subsequent recycling, and greatly improving the efficiency of back sheet peeling. At the same time, completing the cutting of the four sides of the photovoltaic module first, and then tearing off the back sheet can avoid tearing the back sheet.

[0081] Furthermore, the third lifting assembly 254 is a fourth lifting motor, which is fixedly arranged in the middle of the first frame 221. The output end of the fourth lifting motor is passed through the bottom of the first frame 221 and connected to the top of the shell 251. The lifting and lowering of the entire shoveling and rolling clamping assembly 250 can be completed through the fourth lifting motor.

[0082] Furthermore, the fourth lifting component 255 is a fifth lifting motor, which is fixedly arranged on the top of the shell 251. The output end of the fifth lifting motor is passed through the shell 251 and connected to the pressure plate 253. The lifting and lowering of the pressure plate 253 can be completed by the fifth lifting motor alone.

[0083] In some specific embodiments of the present invention, referring to Figure 5 There are two fourth lifting assemblies 255, and both of the two fourth lifting assemblies 255 are fixedly arranged in the housing 251 and connected to the pressing plate 253. Specifically, the two fifth lifting motors are symmetrically arranged, and both are fixedly arranged at the top of the housing 251. The output ends of the two fifth lifting motors are both arranged in the housing 251 and connected to the pressing plate 253. The two fifth lifting motors can ensure the stability of the lifting of the pressing plate 253, and can also ensure the clamping strength of the pressing plate 253 and the pressure shovel 252 on the back plate.

[0084] In some specific embodiments of the present invention, referring to Figure 1 , a discharging conveyor line 300 is provided on one side in the arrangement direction of the rollers 120, and the discharging conveyor line 300 can convey the backboard. One end of the track 210 extends to the top of the discharging conveyor line 300 along the arrangement direction of the multiple rollers 120. Specifically, the ends of the two tracks 210 extend to the top of the discharging conveyor line 300 along the arrangement direction of the multiple rollers 120, so that the first frame 221 can move on the track 210 to the top of the discharging conveyor line 300, and then can drive the backboard clamped by the pressing plate 253 and the pressing shovel 252 to move to the top of the discharging conveyor line 300. The clamping of the backboard can be released by driving the pressing plate 253 away from the pressing shovel 252 through the fifth lifting motor, so that the backboard falls onto the discharging conveyor line 300, and the backboard can be conveyed to the next node for collection through the discharging conveyor line 300. The recycling efficiency is improved.

[0085] In some specific embodiments of the present invention, referring to Figure 1 , the discharging conveyor line 300 and the first blocking assembly 130 are spaced apart. In addition, a collecting box 400 is disposed below the space between the discharging conveyor line 300 and the first blocking assembly 130 and directly opposite to the space. At the same time, the conveying direction of the discharging conveyor line 300 is disposed toward the collecting box 400, so that the backboard falling onto the discharging conveyor line 300 can be conveyed to the collecting box 400 under the action of the discharging conveyor line 300 for easy collection.
