Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic panel recycling, and particularly relates to a waste photovoltaic disassembly processing system. BACKGROUND

[0002] In recent years, with the rise of new energy technology, photovoltaic technology, as a conversion method of solar clean energy, has made great progress. As the life of photovoltaic panels reaches the end, although their power generation performance has been lost, they contain various high-value materials such as silicon, silver, copper, aluminum, glass, and EVA materials. Therefore, the recycling of photovoltaic panels has gradually developed into a specialized industry. The recycling methods of photovoltaic panels mainly include physical method, pyrolysis method, and chemical method. However, regardless of which method, the junction box and aluminum frame of the photovoltaic panel need to be removed first, and then the laminated parts are processed through subsequent processes such as crushing and screening (physical method), high-temperature pyrolysis and separation (pyrolysis method), or chemical swelling and pyrolysis separation (chemical method). In recent years, as more and more people and funds are involved in the photovoltaic panel recycling industry, the recycling technology of photovoltaic panels has gradually matured and standardized, and a comprehensive disassembly assembly line operation mode integrating box disassembly, frame disassembly, and subsequent processes has been basically formed.

[0003] The removal of the aluminum frame, as an important part of the entire operation assembly line, determines the efficiency and difficulty of the subsequent operation to a certain extent. In the current online removal operation of the aluminum frame, the photovoltaic panel is first transported and positioned to the frame disassembly station by a conveying device (conveying roller, conveying belt, etc.), and then the frame profile is removed in the order of short side first and long side second by a frame disassembly device. According to its working form, the frame disassembly device can be divided into two types: one is external pulling type (generally full-automatic assembly line), which generally sets mechanical clamps on both sides of the frame disassembly station, uses the clamps to retract and clamp on the inside of the frame profile, and pulls the frame profile by pulling the clamps to the two sides, so that the frame profile is separated from the laminated part; the other is inside pushing type (generally semi-automatic assembly line), which sets a pushing mechanism that can be opened to the two sides at the frame disassembly station. After the photovoltaic panel is positioned, the pushing mechanism is opened to the two sides along the laminated part surface, thereby pushing the frame profile to separate it from the laminated part.

[0004] But in practical application, because the connection between the frame profile and the laminated piece is relatively close, the above two ways are to realize the separation between the frame profile and the laminated piece through simple physical pressing, and in this process, the edge of the laminated piece is easy to be damaged, resulting in that there are many laminated piece fragments, particles and the like in the separated frame profile, on the one hand, the fragments need to be stripped again manually in the subsequent process of the frame profile, which increases the difficulty of subsequent processing; on the other hand, it also causes waste of materials, resulting in reduction of recovery yield, although the stripped fragments, particles and the like can be introduced into the system again for remediation, which undoubtedly increases the processing procedure and reduces the work efficiency. Therefore, in the separation of the frame profile, it is particularly important to realize accurate removal of the frame profile and maintain the integrity of the laminated piece. SUMMARY

[0031] In combination Figures 1-8 As shown in the figure, the application discloses a waste photovoltaic disassembly and processing system, especially a frame dismounting device contained therein, which is connected to a processing system, generally arranged after a box dismounting device in a previous sequence, and arranged before subsequent processing equipment such as a pyrolysis furnace, a pulverizer, a swelling pool and the like, and used for dismounting an aluminum frame on a photovoltaic panel.

[0032] As Figure 1 As shown in the figure, the application comprises a conveying device 1 used for conveying the photovoltaic panel 0 to a frame dismounting station, the conveying device 1 can adopt a conveying belt, a conveying roller and the like, which can position and convey the photovoltaic panel 0 after box dismounting to the frame dismounting station, and in the conveying process, four positioning vertical rods capable of swinging in an opening and closing manner in the width direction of the conveying device are generally used to clamp and position the photovoltaic panel 0, so that the photovoltaic panel 0 can be positioned and conveyed stably on the conveying device (since the positioning mode is a conventional design scheme in the prior art, and the structure is relatively simple, it will not be described in detail in the application). As Figure 1 In the embodiment shown in the figure, the application adopts two conveying belts arranged side by side to complete the conveying of the photovoltaic panel 0.

[0033] After the photovoltaic panel 0 is conveyed to the position, in order to make the photovoltaic panel 0 separate from the conveying device, so as to facilitate the subsequent rotation of the photovoltaic panel 0, the application further comprises a panel lifting device 2 used for clamping the photovoltaic panel 0 and capable of rotating the photovoltaic panel 0 by 90°, as Figure 1 As shown in the figure, the panel lifting device 2 can realize the lifting of the photovoltaic panel 0 through a plurality of lifting cylinders arranged in a matrix, and realize the clamping of the photovoltaic panel 0 through the cooperation of an upper pressing head mounted on a gantry and the lifting cylinders, and a negative pressure suction cup with telescopic and rotating functions can be generally equipped on the upper pressing head, when it is necessary to adjust the orientation of the photovoltaic panel 0, the photovoltaic panel 0 is adsorbed through the negative pressure suction cup, and the negative pressure suction cup is rotated by 90°, so as to realize the orientation adjustment, and when the frame is dismounted, the short side is generally dismounted first, and then the long side is dismounted, so as to avoid the interference of the corner fittings at the corners of the frame profile. Of course, the panel lifting device 2 can also adopt the form of a liftable rotating platform cooperating with a lower pressing mechanism on the gantry, and the specific mode is more, which will not be enumerated in the application.

[0034] In addition, as the core improvement of the present application, the present application further comprises frame removing device 3 arranged on both sides of lifting plate device 2 for removing the frame profile 0a of photovoltaic panel 0. Frame removing device 3 is a device for removing the frame profile, which is used in cooperation with lifting plate device 2. After lifting plate device 2 clamps photovoltaic panel 0, frame removing device 3 pulls the frame profile to the two sides to remove it from the edge of the laminate. The difference from the traditional dismounting device is that the frame removing device 3 of the present application comprises a bracket 4 (the installation basis of the claw mechanism), a claw mechanism with an upper jaw plate 5 and a lower jaw plate 6 arranged on the bracket 4, and an opening and closing driving mechanism and a forward and backward driving mechanism in transmission connection with the claw mechanism. That is, the present application has an upper jaw plate 5 and a lower jaw plate 6, an opening and closing driving mechanism for driving the upper jaw plate 5 and the lower jaw plate 6 to close or separate, and a forward and backward driving mechanism for driving the frame removing device 3 as a whole to move forward (such as Figure 1 in the middle of the movement) or backward (such as Figure 1 move to both sides).

[0035] The difference from the traditional jaw plate is that, as shown in Figure 3 and 4 , the upper jaw plate 5 and the lower jaw plate 6 of the present application each have a flat pressing surface 7 for abutting against the surface of the laminate 0b, a flat abutting surface 9 for abutting against the edge of the frame profile 0a, and a joint clearance inserting body 8 arranged on one side of the flat abutting surface 9 for inserting into the joint clearance between the laminate 0b and the frame profile 0a. The flat pressing surface 7 and the flat abutting surface 9 are two planes, the former contacts the laminate 0b after being pressed, and the latter abuts against the edge of the frame profile 0a when it is retracted. As shown in Figure 2 , when the upper jaw plate 5 and the lower jaw plate 6 are closed under the driving of the opening and closing driving mechanism, the flat pressing surface 7 can be pressed against the surface of the laminate 0b of photovoltaic panel 0 and remain stable. When the upper jaw plate 5 and the lower jaw plate 6 are retracted after being closed under the driving of the forward and backward driving mechanism, the flat abutting surface 9 can abut against the edge of the frame profile 0a, so as to transmit the pulling force to the frame profile 0a. The joint clearance inserting body 8 of the present application gradually thins in the direction away from the flat abutting surface 9, and a sharp edge 10 is formed at the edge of the joint clearance inserting body 8.

[0036] In use, the application uses the conveying device 1 to position and convey the photovoltaic panel 0 processed by the preceding box opening device to the frame removing station, the panel lifting device 2 lifts the photovoltaic panel 0 and clamps the middle part of the photovoltaic panel 0, and first rotates and adjusts the short side of the photovoltaic panel 0 to the side position (first remove the short side, then remove the long side); after the opening and closing driving mechanism drives the upper jaw plate 5 and the lower jaw plate 6 of the jaw mechanism to open, the advancing and retreating driving mechanism drives the frame removing device 3 to approach the photovoltaic panel 0, so that the upper jaw plate 5 and the lower jaw plate 6 of the jaw mechanism pass over the frame profile 0a of the photovoltaic panel 0, then the opening and closing driving mechanism drives the upper jaw plate 5 and the lower jaw plate 6 of the jaw mechanism to close, so that the flat pressing surface 7 of the upper and lower jaw plates abuts against the surface of the laminated part of the photovoltaic panel 0; the advancing and retreating driving mechanism drives the jaw mechanism to retreat, and the frame removing starts; in the process of frame removing, first, the joint clearing body 8 is inserted into the gap between the laminated part 0b and the frame profile 0a, the edge blade 10 of the joint clearing body 8 can facilitate the insertion of the joint clearing body 8, and as the inserted joint clearing body 8 gradually thickens, it can effectively expand the frame profile 0a. Moreover, the joint clearing body 8 also has a certain cutting effect on the adhesive between the laminated part 0b and the frame profile 0a, and can achieve the loosening of the frame profile 0a and the laminated part 0b. With continuous retreat, the edge of the frame profile 0a abuts against the flat abutting surface 9, the stress increases, and continuously pulls outward, and finally separates from the edge of the laminated part 0b, and the frame removing is completed.

[0037] The specific structure of the upper jaw plate 5 and the lower jaw plate 6 of the application is more, which can be designed according to the specific form of the bracket 4, so as to be flexible and stable. Generally, in order to meet the needs of different types of photovoltaic panels 0 (double-sided panel, single-sided panel, thin frame panel, thick frame panel), it is best to have replaceability, through a carrier plate 11 and the bracket 4 are detachably connected by bolts, clamping and the like, that is, the upper jaw plate 5 and the lower jaw plate 6 both include a carrier plate 11 and a jaw body 12 arranged on the carrier plate 11, the jaw body 12 is installed on the carrier plate 11, and then the carrier plate 11 is installed on the bracket 4.

[0038] As Figure 3 and 4 , the jaw body 12 of the application is provided with a rest 13 on one side facing the frame profile 0a (that is, the right side in Figure 3 and 4 , the side surface of the rest 13 forms the flat abutting surface 9. The vertical projection of the joint clearing body 8 is in the shape of a shell, and the joint clearing body 8 and the bottom surface of the jaw body 12 together form the flat pressing surface 7. The joint clearing body 8 in the shape of a shell on the one hand facilitates direct insertion into the gap between the frame profile 0a and the laminated part 0b while increasing the range of expansion support, and on the other hand, since the edge blade 10 surrounds the edge of the entire working side of the joint clearing body 8, the joint clearing body 8 has sharp edge blades 10 in all directions, so that it is possible to realize linear joint clearing processing in cooperation with the drive. On this basis, as Figure 4As shown in the figure, a plurality of top grooves 14 extending from the center to the edge can also be arranged on the upper surface of the joint cleaning body 8. A high-pressure gas hole 15 is also arranged in the claw body 12, one end of the high-pressure gas hole 15 is communicated with the gas source assembly on the carrier plate 11 through a pipeline 16, and the other end is communicated with the inner end of the top groove 14.

[0039] In this way, the high-pressure gas flow released by the high-pressure gas hole 15 to the top groove 14 on the top surface of the joint cleaning body 8 impacts and vibrates the frame profile 0a, which can further loosen the frame profile 0a and the laminated piece 0b, and the injection of the high-pressure gas flow can also pressurize and fill the internal gap of the frame of the photovoltaic panel 0, so that the frame profile 0a of the photovoltaic panel 0 is further expanded to form loosening. Thus, the integrity of the laminated piece 0b during frame disassembly is ensured, the fragments and slag residues in the frame profile are reduced, the subsequent processing difficulty is reduced, and the frame disassembly efficiency and economic benefits are improved. The gas source assembly can adopt central centralized gas supply or direct end gas supply. In the case of direct end gas supply, the gas source assembly generally includes an end gas cylinder 17 fixedly arranged on the carrier plate 11, and the end gas cylinder 17 is communicated with the high-pressure gas hole 15 on the claw body 12 through the pipeline 16. That is, in this case, the end gas cylinder 17 acts as a temporary storage medium for high-pressure gas, which can to some extent alleviate the problem of unstable gas pressure caused by uncontrollable factors such as air compressor damage and gas pipeline cracking, ensure the normal operation of the equipment in the short term in case of emergency, have a short buffering time window, and maintain stable working gas pressure.

[0040] The high-pressure gas flow released by the top groove 14 of the joint cleaning body 8 can be continuously released after the joint cleaning body 8 is inserted into the gap, realizing rapid expansion and support of the internal cavity gap of the frame profile 0a, but better is that an electromagnetic valve 18 can be arranged on the pipeline 16. The electromagnetic valve 18 can realize intermittent conduction of the pipeline 16 under control, so as to form a pulse type high-pressure gas flow at the top groove 14. This pulse type pressure release can provide better air hammer effect, realize the shock and impact of the frame profile 0a, and form repeated impact and pulling of the adhesive between the frame profile 0a and the laminated piece 0b under high-speed vibration, so that the adhesive is more quickly fatigued and broken. At the same time, it can also avoid the situation that the edge of the laminated piece 0b is broken due to too high pressure under continuous gas supply. On this basis, considering that the joint cleaning body 8, the claw body 12 and the table 13 are metal materials with high hardness, in order to prevent the pressure in the frame gap from being too large, causing the flat surface 7 to cause too much rigid extrusion to the glass panel of the laminated piece 0b, causing the glass panel to break, such as Figure 3As shown, the present application can also be provided with a rubber layer 19 on the flat pressing surface 7. But the rubber layer 19 will increase the friction to a certain extent, affecting the smoothness of the flat pressing surface 7 when moving. Therefore, the bottom surface of the rubber layer 19 is coated with a hardening coating for reducing the friction between the rubber layer 19 and the surface of the laminated piece 0b, which can reduce the friction without affecting the cushioning of the rubber layer 19, ensuring the smoothness of its movement.

[0041] Regarding the bracket 4 of the present application, as shown in Figure 2 and 5 , the structure can be that the bracket 4 includes a frame-shaped main frame body 20 arranged along the length direction of the side edge of the photovoltaic panel 0, and the two ends of the main frame body 20 are provided with guide grooves 21 extending transversely, the main frame body 20 is clamped on the advance and retreat guide rail 22 below through the guide grooves 21, and forms a sliding fit with the advance and retreat guide rail 22. The advance and retreat guide rail 22 serves as a guide base and cooperates with the guide grooves 21 to complete the guidance of the advance and retreat of the main frame body 20. The advance and retreat driving mechanism of the present application is used to drive the advance and retreat of the entire frame dismounting device 3, which is generally connected with the main frame body 20 and drives the main frame body 20 to move along the advance and retreat guide rail 22. The specific form of the advance and retreat driving mechanism can adopt the screw-nut pair form as shown in Figure 1 , or directly adopt linear air cylinder driving or other similar telescopic driving forms. As shown in Figure 5 , the inner side edge of the main frame body 20 is provided with a long vertical plate 23, and the two ends of the long vertical plate 23 are connected with the main frame body 20 through reinforcing plates 24 to ensure the overall structural strength and stability. The claw mechanism is installed on the long vertical plate 23.

[0042] When the long vertical plate 23 is used as the installation base of the claw mechanism, as shown in Figure 2 and 6 and 7, the claw mechanism of the present application includes a first supporting plate 25, a pair of L-shaped second supporting plates 26 are symmetrically arranged on the upper part and the lower part of the first supporting plate 25, the upper claw plate 5 and the lower claw plate 6 are respectively installed on the upper and lower second supporting plates 26 through the supporting plates 11, and the second supporting plates 26 can move in the up-down direction under the driving of the opening and closing driving mechanism. That is, the opening and closing of the upper claw plate 5 and the lower claw plate 6 is actually realized by the up-down opening and closing of the second supporting plates 26 on which they are mounted. In order to ensure the stability of the up-down movement of the second supporting plates 26, the opposite side of the first supporting plate 25 to the second supporting plate 26 is also provided with a “[” shaped stable buckle 27, and the vertical edge of the second supporting plate 26 is slidably arranged in the stable buckle 27. As shown in Figure 2 , that is, a “[” shaped piece is welded or bolted on the upper part and the lower part of the first supporting plate 25, and the vertical edge of the first supporting plate 25 passes through the guide opening formed between the two.

[0043] As to the specific driving form of the second supporting plate 26, it can be as shown in Figure 6 and 7 The back surface of the second supporting plate 26 is further provided with a connecting plate 28, and the first supporting plate 25 is provided with a lifting hole 29 matched with the connecting plate 28 at a position opposite to the connecting plate 28, and the connecting plate 28 is arranged in the lifting hole 29 and can stably move up and down in the lifting hole 29. In addition, vertical side guide rails are arranged at the sides of the lifting hole 29, and the connecting plate 28 is further limited by the sliding block arranged at the side of the connecting plate 28. Since the structure is relatively simple, it will not be described here. At this time, the opening and closing driving mechanism can be two opening and closing cylinders 30 arranged on the back surface of the first supporting plate 25. The output ends of the two opening and closing cylinders 30 are arranged opposite to each other, the upper one faces downward, and the lower one faces upward, and are respectively connected with the connecting plate 28 to form the up and down driving of the second supporting plate 26.

[0044] The long vertical plate 23 is provided with three groups of clamping jaw mechanisms arranged side by side along the length direction of the long vertical plate 23. Among the three groups of clamping jaw mechanisms, the two clamping jaw mechanisms at the two ends can reciprocate along the length direction of the long vertical plate 23 under the driving of the translation driving mechanism to form the joint gap cleaning treatment of the whole length direction of the side edge of the photovoltaic panel 0. At the same time, this way can also be beneficial to the uniform distribution of the pulling force on the frame profile 0a by the multiple clamping jaw mechanisms. In addition, by adjusting the positions of the clamping jaw mechanisms at the two ends, the length of the photovoltaic panel 0 can also be adapted.

[0045] In this structure, as shown in Figure 2 , the long vertical plate 23 is provided with a guide rod 31 extending along the length direction of the long vertical plate 23 on the side opposite to the first supporting plate 25 (the left side in the figure), as shown in Figure 2 and 6As shown in the figure, the first supporting plate 25 is provided with a sliding ear 32 sleeved on a guide rod 31, and the guide rod 31 and the sliding ear 32 cooperatively form a translation guide for the first supporting plate 25. The middle part of the long vertical plate 23 is provided with a slot 33 extending along the length direction of the long vertical plate 23, and the middle part of the first supporting plate 25 is provided with a connecting sleeve 34 extending to the back side of the long vertical plate 23 through the slot 33, and the connecting sleeve 34 is connected with a driving force to drive the first supporting plate 25. In order to realize the synchronous driving (separation or closing) of the first supporting plate 25 of the two jaw mechanisms through one driving shaft, the translation driving mechanism comprises a driving screw 35 provided between the reinforcing plates 24 and in transmission connection with the translation driving motor. Among the three jaw mechanisms, the connecting sleeve 34 of the middle jaw mechanism is sleeved on the middle segment of the driving screw 35 and is in rotational cooperation with the driving screw 35, and the corresponding jaw mechanism does not move translationally. The connecting sleeves 34 of the two jaw mechanisms at the two ends are sleeved on the two ends of the driving screw 35 and are in threaded cooperation with the driving screw 35, the thread directions of the two ends of the driving screw 35 are opposite, when the driving screw 35 rotates clockwise, the two jaw mechanisms are close to each other, and vice versa, so that the distance adjustment of the three jaw mechanisms is realized. When the two jaw mechanisms at the two ends are in position translation, they can walk along the length of the edge of the photovoltaic panel 0, and the whole edge is processed for joint cleaning and loosening.

[0046] In the working process of the present application, one of the working steps is that the joint cleaning body 8 is inserted into the joint gap. For some panel bodies, the frame profile 0a is not completely symmetrical, and the upper side edge can be longer, or the lower side edge can be longer. In most cases, the cross section of the frame profile 0a is as shown in the figure. Figure 8 Therefore, the joint cleaning body 8 of the present application should have an adaptive adjustment fine adjustment function. Therefore, as shown in the figure, Figure 7As shown in the figure, the horizontal edge of the second supporting plate 26L is provided with a clamping interface 36 extending along the length direction of the horizontal edge, and the top of the carrier plate 11 is provided with a T-shaped clamping strip 37 matched with the clamping interface 36. The clamping strip 37 is clamped in the clamping interface 36 and forms a sliding fit with the second supporting plate 26, so that the carrier plate 11 can move left and right along the clamping interface 36. In order to realize the real-time online adjustment of the position of the carrier plate 11, the horizontal edge of the second supporting plate 26 is further provided with a fine adjustment air cylinder 38, and the output end of the fine adjustment air cylinder 38 is connected with the clamping strip 37. On the one hand, the fine adjustment air cylinder 38 can drive the fine adjustment of the position of the upper jaw plate 5 or the lower jaw plate 6 carried on the carrier plate 11, and on the other hand, when the joint body 8 is inserted into the gap, the action distance is relatively short, so the fine adjustment air cylinder 38 with higher precision can be used for driving insertion instead of driving control through the advance and retreat driving mechanism, and then the linear joint loosening is realized by using the translation driving mechanism, and after the joint loosening is completed, the frame is disassembled by retreating through the advance and retreat driving mechanism, so that the precision of the driving action is further improved, and the power waste caused by directly driving insertion through the advance and retreat driving mechanism is reduced.

[0047] In addition, in order to further improve the use convenience of the present application, the material is conveniently removed (the dismounting of the frame profile 0a), as shown in the figure, Figure 8 As shown in the figure, the first supporting plate 25 is a few-shaped body arranged in the longitudinal direction, and the notch faces the photovoltaic panel 0, and the recess of the few-shaped body is provided with a frame supporting groove 39. On the one hand, the frame supporting groove 39 can be used as the supporting basis of the frame profile 0a, and on the other hand, it can also constrain the outer contour of the frame profile 0a to a certain extent, so as to prevent the frame profile 0a from being excessively deformed in the process of dismounting the frame and pulling or joint loosening, thereby further improving the overall stability.

[0048] In terms of dismounting the material, as shown in the figure, Figure 8 The present application is provided with a material removal mechanism at the frame supporting groove 39. The upper part and the lower part of the back of the frame supporting groove 39 are provided with sliding rods 40 extending in the transverse direction, the sliding rods 40 pass through the limiting frame 41 fixedly arranged in the recess of the first supporting plate 25 and form a sliding fit with the limiting frame 41. The end of the sliding rod 40 is provided with a first stopper 42. The material removal mechanism comprises a top block 43 arranged in the frame supporting groove 39, the back of the top block 43 is connected with a top removal air cylinder 45 fixedly arranged on the first supporting plate 25 through a driving rod 44. The top block 43 is further provided with side pin rods 46 on the upper side and the lower side, the side pin rods 46 pass through the frame supporting groove 39 and are provided with second stoppers 47 at the ends, and the outer sleeve of the side pin rods 46 between the second stoppers 47 and the outer side of the frame supporting groove 39 is provided with a spiral spring 48.

[0049] When discharging, after the frame dismounting device 3 is retracted to the position, the upper jaw plate 5 and the lower jaw plate 6 are opened, the top stripping cylinder 45 first strips out the frame support groove 39 together with the internal frame profile 0a, and exceeds the position of the upper jaw plate 5 and the lower jaw plate 6. At this time, the frame support groove 39 is blocked by the first stop head 42, the position reaches the limit, with the continuous action of the top stripping cylinder 45, the driving rod 44 compresses the spiral spring 48 and drives the top block 43 to continuously move, strips out the frame profile 0a from the frame support groove 39, and falls into the discharging area or the collecting box arranged on the ground. The top stripping cylinder 45 not only drives the frame support groove 39, but also continuously drives the top block 43, which has a long driving stroke, and in the case of a short cylinder body, a multi-section telescopic cylinder similar to a sleeve structure can be considered.
