Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and particularly to a cleaning device for the frames of waste photovoltaic modules. Background Art

[0002] A photovoltaic module, also called a solar panel, is a power generation device that generates direct current when exposed to sunlight. It mainly includes solar cells, photovoltaic glass, a frame, and an EVA film. The frame is usually composed of aluminum alloy profiles, which are used to protect the module and enhance its mechanical strength. Components such as solar cells and photovoltaic glass are bonded to the frame through the EVA film to form a complete photovoltaic module.

[0003] In related technologies, after disassembling a photovoltaic module, it is necessary to remove the EVA film adhered to the frame. Existing glue removal methods are mostly manual glue removal, which has problems such as low efficiency and high labor intensity for workers.

[0004] A Chinese patent document with the authorization announcement number CN114505273B discloses a glue removal device. The glue removal device includes: a loading component, a glue removal component, and a moving module. The loading component is used to load and fix the object to be deglued; the glue removal component is used to clean the residual glue adhered to the object to be deglued; the moving module is connected to at least one of the loading component and the glue removal component, and is used to drive at least one of the loading component and the glue removal component to move, so that one of the loading component and the glue removal component moves relative to the other.

[0005] The above-mentioned glue removal device places the object to be deglued on the loading component, and then the moving module drives at least one of the loading component and the glue removal component to move, that is, the moving module drives the loading component to move, or drives the glue removal component to move, or drives the loading component and the glue removal component to move simultaneously, so that a relative movement is generated between the loading component and the glue removal component, and further the object to be deglued placed on the loading component moves relative to the glue removal component, and the colloid on the object to be deglued is scraped off by the glue removal part.

[0006] However, due to the high viscosity of the EVA film on the photovoltaic panel frame and various textures usually existing on the photovoltaic panel frame, there is usually residual colloid when using a scraper to clean it, resulting in poor cleaning effect and the need to repeatedly scrape the photovoltaic frame, with low cleaning efficiency; if a steel wool is used for glue removal, although the cleaning effect can be improved, the steel wool itself is prone to getting stuck with residual glue and is not easy to clean. After too much colloid adheres to the steel wool, its cleaning ability will be affected, and a new steel wool needs to be replaced, resulting in a high cleaning cost. Summary of the Invention

[0007] The present invention provides a cleaning device for the frames of waste photovoltaic modules, aiming to solve the problem of low glue removal efficiency in related technologies.

[0008] The waste photovoltaic module frame cleaning equipment of the present invention includes: a frame body, a transfer assembly, and a cleaning assembly; Both the transfer assembly and the cleaning assembly are arranged on the frame body; The cleaning assembly includes a mounting seat, a cleaning frame, a first driving member, a transmission belt, a wire brush, and a vibration unit. One end of the mounting seat is connected to the frame body, and the other end of the mounting seat is provided with the cleaning frame. The transmission belt is rotationally fitted on the cleaning frame. The first driving member is used to drive the transmission belt to rotate. A plurality of wire brushes are spaced apart and distributed on the transmission belt. The vibration unit is arranged on the cleaning frame, and the vibration unit can drive the wire brush to vibrate.

[0009] Beneficial effects: Place the photovoltaic module frame on the transfer assembly. The transfer assembly can drive the photovoltaic module frame to move within the frame body. During the movement of the photovoltaic module frame within the frame body, it will pass through the cleaning frame. The first driving member drives the transmission belt to rotate around the cleaning frame, thereby driving the wire brush to rotate around the cleaning frame. When the wire brush is located between the cleaning frame and the photovoltaic module frame, the cleaning frame presses the wire brush against the photovoltaic module frame, and the wire brush and the photovoltaic module frame move relative to each other, so that the wire brush can scrape the colloid on the photovoltaic module frame. When the wire brush detaches from the photovoltaic module frame, the vibration unit causes the wire brush to vibrate, and the colloid attached to the wire brush is shaken off through vibration, thereby realizing the cleaning of the wire brush, reducing the replacement frequency of the wire brush, and reducing the cleaning cost.

[0010] Preferably, the wire brush includes a fixed seat, a first mounting plate, a second mounting plate, a first elastic member, and a wire. The fixed seat is fixedly connected to the transmission belt. The first mounting plate is fixedly arranged at one end of the fixed seat. The second mounting plate is slidably fitted with the fixed seat. The first elastic member is arranged between the first mounting plate and the second mounting plate. Two ends of the first elastic member are respectively connected to the first mounting plate and the second mounting plate. The wire is wound around the first elastic member. A stop block is arranged on the second mounting plate. The stop block can extend into the cleaning frame and abut against the vibration unit. The vibration unit can push the second mounting plate away from the first mounting plate.

[0011] By arranging the stop block, when the wire brush finishes cleaning the photovoltaic module frame, the vibration unit pushes the stop block, so that the second mounting plate moves away from the first mounting plate, thereby stretching the first elastic member, so that the wire on the first elastic member is stretched, and the gap between the wires on the first elastic member is enlarged, which is beneficial to the colloid falling off from the wire.

[0012] Preferably, the first elastic member is a spring, and the pitches of the first elastic member are distributed from large to small in sequence, and the pitch of its end close to the first mounting plate is the largest.

[0013] By winding steel wires around the first elastic member, a rough surface is formed. When the steel wires pass through the photovoltaic module frame, the colloid attached to the photovoltaic module frame can be scraped off. In addition, the pitches of the first elastic member are distributed from large to small in sequence. The photovoltaic module frame first contacts the first half section with a larger pitch of the first elastic member. The first half section of the first elastic member is used to scrape off the large pieces of residual glue on the photovoltaic module frame. The large pieces of residual glue will adhere to the first half section of the first elastic member. Then, the second half section with a smaller pitch of the first elastic member contacts the photovoltaic module frame again and cleans up the remaining fine residual glue. When the wire brush vibrates, due to the larger pitch of the first half section of the first elastic member, the large pieces of residual glue can fall from the gaps between the two coils of the first elastic member, thus preventing the residual glue from remaining on the first elastic member.

[0014] Preferably, the vibration unit includes a vibration housing, a vibration block, and a second driving member. The vibration housing is fixedly arranged on the cleaning frame. The vibration block at least partially extends into the vibration housing and is slidably matched with the vibration housing. The second driving member is arranged in the vibration housing, and its output end is connected to the vibration block. The second driving member is used to drive the vibration block to reciprocate.

[0015] The second driving member drives the vibration block to reciprocate, so that the vibration block continuously impacts the stop block, thereby generating vibration. At the same time, the vibration block can also limit the stop block, thus preventing the stop block from resetting, and further preventing the first elastic member from contracting, ensuring that the gap between the steel wires is at the maximum value when the wire brush vibrates, which is beneficial to the colloid falling off from the gaps between the steel wires and ensuring the cleaning effect on the wire brush.

[0016] Preferably, a water spray pipe is further arranged between the first mounting plate and the second mounting plate. The water spray pipe is provided with nozzles. A water storage tank is arranged on the cleaning frame. A rotating disk is arranged on the side wall of the water storage tank. The rotating disk is provided with a plurality of water outlets spaced apart along its circumferential direction. Each water outlet corresponds to one water spray pipe. The water outlet and the water spray pipe are communicated through a pipeline.

[0017] When the wire brush removes glue from the photovoltaic module frame and the wire brush self-cleans, the water in the water storage bin can enter the water spray pipe and spray outwards, assisting the wire brush to remove glue from the photovoltaic module frame, avoiding the situation that the colloid still remains on the photovoltaic module frame after the wire brush scrapes the colloid off the photovoltaic module frame. When the wire brush vibrates, the water spray pipe sprays water on the wire brush, thereby flushing away the colloid remaining on the wire brush and preventing the colloid from adhering to the wire brush and affecting the cleaning efficiency of the wire brush.

[0018] Preferably, the inside of the rotating disk is hollow, and a shielding plate is arranged inside the rotating disk. The shielding plate is in a fan-shaped structure and is connected to the water storage tank. The shielding plate is located in the upper area of the rotating disk, so as to close the water outlet in the upper area of the rotating disk.

[0019] Setting the shielding plate can shield the water outlet located in the upper half area of the rotating disk, so that the water spraying pipe will only spray water when the wire brush removes glue from the photovoltaic module frame and when the wire brush self-cleans, avoiding the water spraying pipe spraying water everywhere and saving water resources.

[0020] Preferably, a lifting arm is arranged on the mounting seat, and the cleaning frame is arranged at the bottom end of the lifting arm. The lifting arm can drive the cleaning frame to move up and down.

[0021] Setting the lifting arm can adjust the height of the cleaning component. When the photovoltaic module frame enters and leaves the frame body, the lifting arm can lift the cleaning component upward to prevent the cleaning component from hindering the photovoltaic module frame from entering or leaving the frame body.

[0022] Preferably, a third driving member is arranged on the lifting arm, and the output end of the third driving member is connected to the cleaning frame. The third driving member can drive the cleaning frame to approach or move away from the lifting arm.

[0023] When the wire brush removes glue from the photovoltaic module frame, the third driving member drives the cleaning frame to approach or move away from the lifting arm, so as to realize the reciprocating movement of the cleaning frame. The wire brush and the cleaning frame move reciprocally synchronously, so that the wire brush can move reciprocally relative to the photovoltaic module frame, thereby increasing the cleaning area of the wire brush. The reciprocating movement of the wire brush can repeatedly scrape the same area, thereby improving the cleaning ability of the wire brush and avoiding the glue remaining on the photovoltaic module frame.

[0024] Preferably, a clamping component is arranged on the frame body. The clamping component includes an upper clamping plate and a lower clamping plate. A first lifting mechanism is arranged at the top of the frame body, and a second lifting mechanism is arranged at the bottom of the frame body. The upper clamping plate is rotatably matched with the first lifting mechanism, and the lower clamping plate is rotatably matched with the second lifting mechanism.

[0025] By setting the clamping component, when the cleaning component cleans the photovoltaic module frame, the upper clamping plate and the lower clamping plate respectively abut against the top surface and the bottom surface of the photovoltaic module frame, so as to prevent the photovoltaic module frame from shaking. After the cleaning component finishes cleaning the two side walls of the photovoltaic module frame, the upper clamping plate and the lower clamping plate can clamp the photovoltaic module frame and rotate 90 degrees. At this time, the cleaning component can clean the remaining two side walls of the photovoltaic module frame.

[0026] Preferably, a cross rail is provided on the frame body, a moving seat is slidably fitted on the cross rail, a longitudinal rail is provided on the moving seat, and the mounting seat is slidably fitted on the longitudinal rail.

[0027] The effect is that the cross rail is provided to enable the moving seat to move on the cross rail, and the longitudinal rail is provided on the moving seat to enable the mounting seat to move on the longitudinal rail, thereby realizing the movement of the mounting seat in the horizontal plane. By adjusting the position of the mounting seat, the position of the cleaning component can be adjusted, which is convenient for aligning the cleaning component with the photovoltaic module frame.

[0028] Adopting the above technical solution, the beneficial effect of the present invention is as follows: According to the waste photovoltaic module frame cleaning device of the embodiment of the present invention, the photovoltaic module frame is placed on the transfer component, and the transfer component can drive the photovoltaic module frame to move in the frame body. During the movement of the photovoltaic module frame in the frame body, it will pass through the cleaning frame. The first driving member drives the transmission belt to rotate around the cleaning frame, thereby driving the wire brush to rotate around the cleaning frame. When the wire brush is located between the cleaning frame and the photovoltaic module frame, the cleaning frame presses the wire brush against the photovoltaic module frame, and the wire brush and the photovoltaic module frame move relative to each other, so that the wire brush can scrape the colloid on the photovoltaic module frame. When the wire brush is separated from the photovoltaic module frame, the vibration unit is used to vibrate the wire brush, and the colloid attached to the wire brush is shaken off through vibration, thereby realizing the cleaning of the wire brush, reducing the replacement frequency of the wire brush, and reducing the cleaning cost.

[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] As Figures 1 to 9 shown, the waste photovoltaic module frame cleaning device of the present invention includes: a frame 1, a transfer assembly, a cleaning assembly, and a clamping assembly. The frame 1 is used to support each component. The transfer assembly is used to drive the movement of the photovoltaic module frame. The cleaning assembly is used to clean the colloid on the photovoltaic module frame. The clamping assembly is used to fix the photovoltaic frame.

[0041] Specifically, as Figure 1 shown, the frame 1 is a frame structure, and the bottom of the frame 1 can be supported on the ground.

[0042] As Figure 1 and Figure 2 shown, the transfer assembly includes a driving shaft 22, a conveyor belt 21, and a driving motor. The two driving shafts 22 are spaced apart on the frame 1.

The driving motor is fixedly arranged on the frame 1 and is fixedly connected to one of the driving shafts 22. The driving motor drives the driving shaft 22 to rotate, thereby driving the conveyor belt 21 to rotate in a cycle.

[0043] As Figures 1 to 5As shown, there are two cleaning components, which are respectively arranged on the left and right sides of the frame body 1. The cleaning component includes a mounting seat 41, a cleaning frame 51, a transmission belt 54, a first driving member 55, a wire brush 56 and a vibration unit. There are two groups of horizontal rails 31 on the frame body 1. Each group of horizontal rails 31 has two horizontally spaced horizontal rails 31. Each horizontal rail 31 extends in the left-right direction. A moving seat 32 is slidably fitted on each group of horizontal rails 31. A longitudinal rail 33 extending in the front-back direction is provided on each moving seat 32. A mounting seat 41 is slidably fitted on each longitudinal rail 33. By moving the moving seat 32 along the horizontal rail 31 and the mounting seat 41 along the longitudinal rail 33, the movement of the mounting seat 41 in the horizontal plane can be realized. A lifting arm 42 is provided on each mounting seat 41. The lifting arm 42 is fixedly connected to the mounting seat 41. A hydraulic cylinder is fixedly provided on the lifting arm 42. The output end of the hydraulic cylinder can move up and down. The output end of the hydraulic cylinder is fixedly connected to a mounting rod 43. The cleaning frame 51 includes a first frame 511 and a second frame 512. Both the first frame 511 and the second frame 512 are of a frame structure. The second frame 512 is horizontally arranged. The first frame 511 is inclined. And the bottom end of the first frame 511 is fixedly connected to the second frame 512. A plurality of spaced mounting holes are provided at the bottom of the mounting rod 43. Connecting rods are provided on the side walls of the first frame 511 and the second frame 512. Each connecting rod extends into the corresponding mounting hole and is slidably fitted with the mounting hole. A third driving member 44 is fixedly provided on the mounting rod 43. The third driving member 44 is a driving motor. The output end of the third driving member 44 is fixedly connected to a double-threaded driving rod. The double-threaded driving rod is in threaded cooperation with the first frame 511. By driving the double-threaded driving rod to rotate, the third driving member 44 can further make the cleaning frame 51 reciprocate, so as to periodically approach or move away from the mounting rod 43.

[0044] Two groups of supporting wheels 52 are respectively provided at both ends of the first frame 511. Each group of supporting wheels 52 has two supporting wheels 52. The two supporting wheels 52 in each group of supporting wheels 52 are parallel and spaced on both sides of the first frame 511. A connecting shaft is fixedly provided between the two supporting wheels 52. The connecting shaft is rotatably fitted with the first frame 511. Two supporting blocks 53 are provided at one end of the second frame 512 away from the first frame 511. The two supporting blocks 53 are respectively fixedly provided on the second frame 512. The transmission belt 54 is sleeved on the two groups of supporting wheels 52 and the supporting blocks 53. The transmission belt 54 is in static friction cooperation with the supporting wheels 52. The transmission belt 54 is in sliding cooperation with the supporting blocks 53. The two groups of supporting wheels 52 and the supporting blocks 53 support the transmission belt 54, so that the transmission belt 54 forms a right-angled triangle structure. A first driving member 55 is also fixedly provided on the first frame 511. The first driving member 55 is a motor. The output end of the first driving member 55 is fixedly connected to the supporting wheel 52 at the bottom end of the first frame 511. By driving the supporting wheel 52 to rotate, the first driving member 55 can further drive the transmission belt 54 to circulate around the cleaning frame 51.

[0045] As Figure 4 shown Figure 7 and Figure 8 shown in the figure, a plurality of mounting grooves are provided on the transmission belt 54 at parallel intervals, and a wire brush 56 is provided in each mounting groove. The wire brush 56 includes a fixing base 561, a first mounting plate 562, a second mounting plate 563, a first elastic member 564 and a wire. The fixing base 561 is fixedly arranged in the mounting groove, the first mounting plate 562 is fixedly arranged on the fixing base 561, the second mounting plate 563 is slidably fitted on the fixing base 561, the first mounting plate 562 and the second mounting plate 563 are arranged at parallel intervals, a stop block 565 is fixedly arranged on the second mounting plate 563, the stop block 565 passes through the mounting groove and extends into the cleaning frame 51, the first elastic member 564 is arranged between the first mounting plate 562 and the second mounting plate 563, the first elastic member 564 is a spring, one end of which is fixedly connected to the first mounting plate 562 and the other end of which is fixedly connected to the second mounting plate 563. The pitch of the first elastic member 564 is distributed from large to small in sequence, and the pitch near the first mounting plate 562 is greater than the pitch near the second mounting plate 563. The wire is wound on the first elastic member 564 (the wire is not shown in the figure).

[0046] As Figures 4 to 6 shown in the figure, the vibration unit includes a vibration housing 61, a vibration block 62 and a second driving member. The vibration housing 61 is fixedly arranged on the second frame 512, the vibration block 62 at least partially extends into the vibration housing 61 and is slidably fitted with the vibration housing 61. The second driving member is fixedly arranged in the vibration housing 61, the second driving member is an electric push rod, the output end of the second driving member is fixedly connected to the vibration block 62, and the vibration housing 61 and the vibration block 62 can abut against the stop block 565. The vibration housing 61 and the vibration block 62 are both provided with inclined plane structures. When the wire brush 56 moves to the vibration housing 61 driven by the transmission belt 54, the stop block 565 abuts against the inclined plane end of the vibration housing 61 and moves along the inclined plane ends of the vibration housing 61 and the vibration block 62, so that the stop block 565 moves from one end of the mounting groove to the other end in the mounting groove, and then pushes the second mounting plate 563 away from the first mounting plate 562, and the first elastic member 564 stretches. When the stop block 565 moves to the other end of the mounting groove, the stop block 565 can cross the inclined plane end of the vibration block 62. At this time, the vibration block 62 abuts against the stop block 565 and prevents the stop block 565 from resetting, thereby preventing the first elastic member 564 from rebounding. At this time, the second driving member drives the vibration block 62 to move quickly back and forth, so that it can continuously collide with the stop block 565, thereby generating vibration. The stop block 565 transfers the vibration to the first elastic member 564, and the first elastic member 564 transfers the vibration to the wire, so as to realize the vibration of the wire brush 56.

[0047] As Figure 4 shown Figure 5 in Figure 7and Figure 9 As shown in Figure 9 , a water spray pipe 74 is provided between a first mounting plate 562 and a second mounting plate 563. The water spray pipe 74 is provided with a plurality of spray holes evenly spaced along its axial direction. The water spray pipe 74 is a telescopic pipe, one end of which is fixedly connected to the first mounting plate 562 and the other end of which is fixedly connected to the second mounting plate 563. When the second mounting plate 563 moves away from the first mounting plate 562, the water spray pipe 74 is correspondingly stretched, and when the second mounting plate 563 moves closer to the first mounting plate 562, the water spray pipe 74 is correspondingly shortened. A water storage tank 71 is fixedly arranged between a first frame 511 and a second frame 512. A water pump is arranged in the water storage tank 71. A rotating disk 72 is arranged on the side wall of the water storage tank 71. The rotating disk 72 is rotatably connected to the water storage tank 71. The rotating disk 72 is of a hollow structure, and its interior is communicated with the water storage tank 71. A plurality of water outlets evenly spaced along its circumferential direction are arranged on the side wall of the rotating disk 72. Each water outlet corresponds to a water spray pipe 74, and each water outlet is communicated with the water spray pipe 74 through a rubber hose. The water pump in the water storage tank 71 can pump the water in the water storage tank 71 into the rotating disk 72. The water in the rotating disk 72 enters the water spray pipe 74 through the rubber hose under the action of pressure and is sprayed out from the spray holes on the water spray pipe 74. A shielding plate 73 is further arranged in the rotating disk 72. The shielding plate 73 is of a fan-shaped structure. The shielding plate 73 is located in the upper half of the rotating disk 72. The shielding plate 73 is fixedly connected to the water storage tank 71. The outer arc surface of the shielding plate 73 fits and slides with the inner wall of the rotating disk 72. The shielding plate 73 can close the water outlets located in the upper half area of the rotating disk 72.

[0048] As Figure 1 and Figure 2 As shown in Figure 2 , the clamping assembly includes an upper clamping plate 81 and a lower clamping plate 82. A first lifting mechanism 83 is fixedly arranged at the top of the frame body 1, and a second lifting mechanism 84 is fixedly arranged at the bottom of the frame body 1. Both the first lifting mechanism 83 and the second lifting mechanism 84 are hydraulic cylinders. The bottom end of the first lifting mechanism 83 is fixedly connected to a first lifting seat, and the top end of the second lifting mechanism 84 is fixedly connected to a second lifting seat. The upper clamping plate 81 is rotatably matched with the first lifting seat. A first rotating motor is fixedly arranged in the first lifting seat. The output end of the first rotating motor is fixedly connected to the upper clamping plate 81. The first rotating motor can drive the upper clamping plate 81 to rotate relative to the first lifting seat. The upper clamping plate 81 and the lower clamping plate 82 are spaced up and down. The lower clamping plate 82 is rotatably matched on the second lifting seat. A second rotating motor is fixedly arranged in the second lifting seat. The output end of the second rotating motor is fixedly connected to the lower clamping plate 82. The second rotating motor can drive the lower clamping plate 82 to rotate relative to the second lifting seat.

[0049] The implementation principle of the waste photovoltaic module frame cleaning equipment in the embodiment of the present invention is as follows: Place the photovoltaic module frame on the conveyor belt 21. The driving motor drives the conveyor belt 21 to rotate cyclically through the driving shaft 22, so as to feed the photovoltaic module frame into the frame body 1 from front to back. At the same time, the moving seat 32 moves on the transverse rail 31, and the mounting seat 41 moves on the longitudinal rail 33, so that the cleaning frame 51 is aligned with the photovoltaic module frame. The hydraulic cylinder on the lifting arm 42 drives the cleaning frame 51 to move downward, so that the wire brush 56 on the cleaning frame 51 can contact the photovoltaic module frame. At this time, the first lifting mechanism 83 and the second lifting mechanism 84 drive the upper chuck 81 and the lower chuck 82 to approach each other. The upper chuck 81 abuts against the top surface of the photovoltaic module frame, and the lower chuck 82 abuts against the bottom surface of the photovoltaic module frame, so as to limit the photovoltaic module frame and prevent it from shaking up and down.

[0050] During the longitudinal movement of the photovoltaic module frame from front to back, the second driving member drives the supporting wheel 52 to rotate, thereby driving the transmission belt 54 to rotate around the cleaning frame 51 and making the wire brush 56 rotate around the cleaning frame 51, so that the wire brush 56 can move horizontally relative to the photovoltaic module frame in the left-right direction. When the wire brush 56 moves to the lower area of the cleaning frame 51, the wire brush 56 contacts the photovoltaic module frame. When the wire brush 56 passes through the surface of the photovoltaic module frame, the colloid attached to the photovoltaic module frame will be scraped off. During the process of scraping the colloid, the part with a larger pitch on the first elastic member 564 contacts the photovoltaic module frame first, so as to clean the large pieces of residual glue. The large pieces of residual glue will be retained in the area with a larger pitch in the first half of the first elastic member 564. Then, the part with a smaller pitch on the first elastic member 564 cleans the photovoltaic module frame again, so as to scrape off the remaining fine colloid and ensure that the residual glue is completely cleaned. During the cleaning process, the third driving member 44 drives the double-threaded driving rod to rotate, thereby making the cleaning frame 51 reciprocate in the front-back direction relative to the mounting rod 43, so that the wire brush 56 can reciprocate in the front-back direction while moving horizontally relative to the photovoltaic module frame, increasing the cleaning area of the wire brush 56. At the same time, the reciprocating movement of the wire brush 56 in the front-back direction can scrape the same area multiple times, so as to improve the cleaning effect.

[0051] After the wire brush 56 is disengaged from the photovoltaic module frame, the scraped glue blocks will adhere to the wires wound around the first elastic member 564. The transmission belt 54 continues to rotate, causing the stopper 565 to abut against the vibration housing 61 and move along the inclined end of the vibration housing 61. The stopper 565 moves along the inclined end of the vibration housing 61 and the vibration block 62, causing the stopper 565 to move in the installation groove against the elastic force of the first elastic member 564. The first elastic member 564 stretches, and the stretching of the first elastic member 564 can increase its pitch. At this time, the second driving member drives the vibration block 62 to reciprocate, causing the vibration block 62 to continuously strike the stopper 565, thereby generating vibration. Through the vibration, the glue blocks attached to the wires can be shaken off. Since most of the large glue masses are concentrated in the area with a larger pitch in the first half of the first elastic member 564, when the first elastic member 564 stretches, the pitch of the first half of the first elastic member 564 further increases, and the gap between the wires increases, which is conducive to the detachment of the glue from the first elastic member 564. When the stopper 565 passes over the vibration block 62, the first elastic member 564 contracts and returns to its original position.

[0052] During the entire cleaning process, the water in the water storage tank is pumped into the rotating disk 72 by a water pump. Due to the blocking of the shielding plate 73, only the water outlet located in the lower half area of the rotating disk 72 is in the open state. Therefore, only the water spray pipe 74 located in the lower half area of the cleaning frame 51 can communicate with the rotating disk 72. When the wire brush 56 scrapes the glue on the photovoltaic module frame, water is sprayed on the photovoltaic module frame to assist the wire brush 56 in scraping the glue, preventing the scraped glue from adhering to the photovoltaic module frame again, thereby improving the cleaning efficiency. When the wire brush 56 is disengaged from the photovoltaic module frame, the first elastic member 564 stretches, the vibration unit generates vibration, and the vibration is transmitted to the wire brush 56. At this time, by spraying water on the wires of the first elastic member 564 and cooperating with the vibration, the glue attached to the wires can be washed away, realizing the cleaning of the wire brush 56 and preventing the wire brush 56 from losing its cleaning ability due to excessive adhesion of glue.

[0053] After the two sides of the photovoltaic module frame are cleaned, the hydraulic cylinder on the lifting arm 42 drives the cleaning frame 51 to move upward, and the two moving seats 32 move away from each other. The first lifting mechanism 83 and the second lifting mechanism 84 continue to drive the upper chuck 81 and the lower chuck 82 to approach each other, so that the upper chuck 81 and the lower chuck 82 can clamp the photovoltaic module frame. Subsequently, the first rotating motor and the second rotating motor respectively drive the upper chuck 81 and the lower chuck 82 to rotate 90 degrees. The upper chuck 81 and the lower chuck 82 drive the photovoltaic module frame to rotate 90 degrees, and then release the photovoltaic module frame. The cleaning operation is carried out again according to the above steps, so as to realize the cleaning of the four side walls of the photovoltaic module frame.

[0054] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
