Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically to a photovoltaic backsheet mounting device. Background Technology

[0002] A photovoltaic (PV) module has five layers in its cross-section: PV glass, EVA, solar cells, EVA, and a backsheet. The backsheet, located on the back of the solar cells, protects and supports them, providing reliable insulation, water resistance, and aging resistance. It typically has a three-layer structure: an outer protective layer of PVDF with good resistance to environmental corrosion, a middle layer of PET polyester film with good insulation properties, and inner layers of PVDF and EVA with good adhesion. The backsheet is rolled up before cutting.

[0003] In existing technology, after the EVA film is laid on top of the solar cells, it is moved below the backsheet installation area and lifted by a lifting mechanism. Upon contact with the backsheet, the backsheet's clamping device releases, allowing it to fall onto the EVA. The overall size of the backsheet is larger than that of the solar cells. After the photovoltaic module is stacked, it is moved to the next lamination stage. Because the backsheet is placed on the EVA and only in contact with it, without other fixing or limiting mechanisms, it is prone to shifting during movement, thus affecting subsequent processes.

[0044] like Figures 1 to 10 As shown, a photovoltaic backsheet 2 mounting device includes a moving device 1 and a backsheet 2 mounting assembly;

[0045] The moving device 1 is used to move the photovoltaic module that has been laid the second layer of EVA11 and lift it under the back sheet 2. After lifting it to a certain height, it stops. The cells are located under the second layer of EVA11.

[0046] The placing assembly comprises a back plate 2, a clamping component 3, a pressing roller 4 and a cutting component 5. The back plate 2 is in the form of a roll and is rotatably mounted on a support 6. The clamping component 3 comprises a first clamping mechanism 31 and a second clamping mechanism 32. The first clamping mechanism 31 clamps the pulled-out back plate 2 to make it in an inclined shape. The second clamping mechanism 32 is located on both sides of the back plate 2 and is connected with the pressing roller 4. The pressing roller 4 is heated and is driven by a driving device 7 to roll and advance on the back plate 2. The heated pressing roller 4 heats the EVA 11 below the back plate 2 to make it soften, so that the back plate 2 and the EVA 11 below it are attracted, and after passing the cutting component 5, the cutting component 5 cuts the back plate 2. After cutting, the pressing roller 4 continues to move, so that the first clamping mechanism 31 releases the fixation of the back plate 2. The driving device 7 makes the pressing roller 4 return before the next moving device 1 rises after the cut back plate 2 is driven by the moving device 1 to leave. The second clamping mechanism 32 clamps and fixes the back plate 2 during the return of the pressing roller 4. The back plate 2 is pulled out and fixed by the first clamping mechanism 31 and the second clamping mechanism 32 when it moves to the end. The first clamping mechanism 31 acts to fix the back plate 2, while the second clamping mechanism 32 releases the clamping of the back plate 2. It should be noted that the first clamping mechanism 31 clamps the back plate 2 outside the battery piece because the back plate 2 is larger than the battery piece.

[0047] The driving device 7 comprises a motor 71 and a pulley assembly 72. The pulley assembly 72 is connected with the pressing roller 4 through a connecting piece 41. One end of the connecting piece 41 is rotatably connected with the pressing roller 4, and the other end passes through a housing 61 of the pulley assembly 72 and is fixed with the pulley assembly 72. The housing 61 is provided with a sliding groove 611 for the movement of the connecting piece 41. The pressing roller 4 moves to the advancing direction of the rotation fulcrum of the back plate 2. At this time, the motor 71 rotates clockwise to drive the pulley assembly 72 to rotate. The pulley of the pulley assembly 72 drives the connecting piece 41 to advance. The connecting piece 41 drives the pressing roller 4 to move while the pressing roller 4 rotates by itself. The pulley assembly 72 is distributed on both sides of the pressing roller 4 and is driven to move simultaneously by a synchronous rod.

[0048] The first clamping mechanism 31 comprises an upper clamping plate 311 and a lower clamping plate 312. The upper clamping plate 311 is fixed with the support 6 and is bent upward at the end close to the back plate 2 to prevent the pulled-out back plate 2 from moving above the upper clamping plate 311. The lower clamping plate 312 is rotatably connected with the support 6. A first transmission mechanism 33 is arranged between the lower clamping plate 312 and the connecting piece 41 to drive the lower clamping plate 312 to act. Specifically, when the connecting piece 41 moves to the end of the advancing end, the connecting piece 41 drives the lower clamping plate 312 to rotate through the first transmission mechanism 33. The lower clamping plate 312 rotates downward and rotates to a place outside the range of the back plate 2 to prevent affecting the lowering of the back plate 2.

[0049] The first transmission mechanism 33 comprises a first rack 331 in sliding connection with the shell 61 and first gears 332 distributed at both ends of the first rack 331, the first rack 331 is located below the shell 61, the first gears 332 are in rotational connection with the shell 61, both of the first gears 332 are in meshing connection with the first rack 331, and toothed rods 3321 extend from the first gears 332, and both of the toothed rods 3321 are towards the same direction, one of the first gears 332 is connected with the lower clamping plate 312 through a connecting rod 313, the circumferential surface of the connecting rod 313 is fixedly connected with the lower clamping plate 312, the end is connected with the first gear 332, and the first gear 332 is located at the rear, when the first gear 332 rotates, the lower clamping plate 312 is driven to rotate through the connecting rod 313, in order to maintain the stability of the lower clamping plate 312 clamping the back plate 2, the connecting rod 313 is divided into a rod body part 3131 and a threaded part 3132, the threaded part 3132 is in threaded connection with the support 6, and the end is connected with the first gear 332, in order to prevent the lower clamping plate 312 from moving in the axial direction when rotating, the rod body part 3131 is in rotational connection with the cross rod of the support 6, both ends are in sliding connection with the threaded part 3132 in the axial direction, and are fixed in the circumferential direction, and the end of the threaded part 3132 is in sliding connection with the first gear 332 in the axial direction, through the above-mentioned connecting rod 313, the stability of the lower clamping plate 312 is ensured, and the lower clamping plate 312 is prevented from moving in the axial direction of the connecting rod 313. The connecting piece 41 moves between the toothed rods 3321, after contacting the toothed rods 3321, the toothed rods 3321 are driven to rotate, when the connecting piece 41 moves to the front end, the connecting piece 41 drives the toothed rods 3321 to rotate through the arc-shaped rod at the upper end, and then the first gear 332 is driven to rotate, so that the first rack 331 moves backward, the first rack 331 drives the first gear 332 at the rear to rotate, and the lower clamping plate 312 is driven to rotate downward through the connecting rod 313, so as to release the fixation of the back plate 2, when the connecting piece 41 returns to the rear end, the connecting piece 41 drives the lower clamping plate 312 to clamp and fix the end of the back plate 2 through the first gear 332 and the connecting rod 313.

[0050] A guide groove 612 is formed in one side of the shell 61, one end of the guide groove 612 is formed into an arc-shaped groove through upward bending, the roller shaft of the compression roller 4 is in sliding cooperation with the guide groove 612, and the connecting piece 41 and the roller shaft of the compression roller 4 are in longitudinal sliding cooperation, when the connecting piece 41 returns to the rear end, the compression roller 4 is moved upward on the connecting piece 41 through the guidance of the arc-shaped groove, so that the compression roller 4 moves away from the back plate 2, and the back plate 2 is prevented from being continuously heated during the movement of the moving device 1.

[0051] The transmission gear 42 is fixed with the roller shaft of the compression roller 4, and the transmission rack 43 is fixed with the shell 61. When the compression roller 4 moves to the bottom end of the arc-shaped groove, the transmission gear 42 meshes with the transmission rack 43 in the subsequent movement process, so that the compression roller 4 rotates. At this time, the transmission rack 43 is located above the transmission gear 42, so that the compression roller 4 rotates counterclockwise. In combination with the inclined back plate 2, the back plate 2 and the EVA 11 are prevented from having bubbles therebetween.

[0052] The second clamping mechanism 32 includes an upper plate body 321, a lower plate body 322, and a guide plate 323 fixed with the shell 61. The upper plate body 321 and the lower plate body 322 are connected with the connecting piece 41 through springs 324. Both ends of the guide plate 323 are open, and a passage 3231 is formed by bending the upper plate body 321 and the lower plate body 322 into the channel and close to each other, corresponding to one end of the cutting component 5. Specifically, when the upper plate body 321 and the lower plate body 322 advance, they move from outside the upper and lower sides of the guide plate 323, respectively, to prevent them from clamping the back plate 2 during the advancing process. When passing through the bending section of the guide plate 323, the upper plate body 321 and the lower plate body 322 are away from each other. At this time, the springs 324 are compressed. When passing through the bending section, the springs 324 are restored under the action of the springs 324, so that they can enter the passage 3231 when returning. The upper plate body 321 and the lower plate body 322 are close to each other in the passage 3231. The close upper plate body 321 and the lower plate body 322 clamp and move the back plate 2. At this time, the springs 324 are in a stretched state. The guide plate 323 tightly clamps the back plate 2 with the upper plate body 321 and the lower plate body 322. When returning to the end, the upper clamp plate 311 and the lower clamp plate 312 come out of the back plate 2. The springs 324 restore to the state before stretching and are outside the upper and lower sides of the guide plate 323. At the same time that the springs 324 restore, the lower clamp plate 312 rotates upward to clamp and fix the back plate 2. Because the upper plate body 321 and the lower plate body 322 can clamp the back plate 2 only by passing through the passage 3231, the passage 3231 needs to be located in front of the cutting component 5 to ensure that the close upper clamp plate 311 and the lower clamp plate 312 can clamp the back plate 2.

[0053] The cutting component 5 comprises a cutter 51, a support plate 52 and a second transmission mechanism 53. The cutter 51 is located above the back plate 2, the support plate 52 is located below the back plate 2, the connecting piece 41 supports the back plate 2 through the second transmission mechanism 53, and the cutter 51 is lowered to cut the back plate 2. Specifically, the cutter 51 is located above the compression roller 4 in height. The second transmission mechanism 53 comprises a second gear 531, a second rack 532 and a screw rod 533. The second rack 532 is fixed to the lower end of the connecting piece 41. The second rack 532 is provided with the second gears 531 on both sides, and the number of teeth on the inner side is less than that on the outer side. The second gears 531 are fixed to the screw rods 533, and the screw rods 533 are rotationally connected to the shell 61. When the connecting piece 41 drives the second rack 532 to move forward, the second rack 532 is engaged with the second gears 531, so that the two screw rods 533 are rotated, the support plate 52 is lifted on the inner screw rod 533, and the cutter 51 is lowered on the outer screw rod. When the support plate 52 stops rising, the cutter 51 cuts the back plate 2.

[0054] The support plate 52 comprises a movable part 521 and a fixed part 522. The movable part 521 is connected to the second transmission mechanism 53, and the fixed part 522 is connected to the shell 61. Specifically, the movable part 521 is connected to the screw rod 533, and the fixed part 522 is fixedly connected to the shell 61. The fixed part 522 is used for supporting the pulled-out section of the cut back plate 2, so as to facilitate the second clamping mechanism 32 to clamp the back plate 2.

[0055] A third transmission mechanism 8 is arranged between the roller shaft of the back plate 2 and the driving device 7. The third transmission mechanism 8 drives the roller shaft of the back plate 2 to move up and down, so as to adjust the included angle between the advancing compression roller 4 and the back plate 2. The third transmission mechanism 8 comprises a bevel gear pair 81, an adjusting screw rod 82 and a synchronous plate 83. One of the bevel gears of the bevel gear pair 81 is connected to the roller shaft of the belt pulley group, and the other bevel gear is fixed to the adjusting screw rod 82. The adjusting screw rod 82 is rotationally connected to the shell 61. One end of the synchronous plate 83 is threadedly connected to the adjusting screw rod 82, and the other end is connected to a sliding block 84. The sliding block 84 is rotationally matched with the roller shaft of the back plate 2, and is slidingly matched with the support 6. When the motor 71 rotates, the adjusting screw rod 82 is rotated through the bevel gear pair 81, the synchronous plate 83 drives the sliding block 84 to move up and down, and the sliding block 84 drives the back plate 2 to move up and down, so as to adjust the included angle. When the compression roller 4 advances, the sliding block 84 drives the back plate 2 to move down, and when the compression roller 4 returns, the sliding block 84 drives the back plate 2 to move up.

[0056] In summary, the motor 71 drives the belt pulley set to rotate, the belt pulley set drives the connecting member 41 to advance, at the same time, the compression roller 4 translates along the guide groove 612, at the translation stage, the transmission gear 42 engages with the transmission rack 43 to make the compression roller 4 rotate counterclockwise, the second clamping mechanism 32 moves from the outside of the guide plate 323, when moving to the curved section of the guide plate 323, the upper plate body 321 and the lower plate body 322 of the second clamping mechanism 32 move away from each other, the spring 324 is compressed, when passing the curved section, it restores under the action of the spring 324 and is close to the range of the channel 3231. When the compression roller 4 passes the end of the battery piece, the second rack 532 below the connecting member 41 engages with the second gear 531 on both sides, through the rotation of the two screw rods 533, the movable part 521 is lifted, the cutter 51 is lowered, and the fixed part 522 supports the pulled back plate 2, in the process of the compression roller 4 moving forward, the belt pulley set makes the compression roller 4 lower through the bevel gear pair 81, the adjusting screw rod 82, the synchronization plate 83 and the sliding block 84. When the compression roller 4 returns, the upper plate body 321 and the lower plate body 322 enter the channel 3231 and are guided, then the back plate 2 is clamped and moved, when returning to the end, the lower clamping plate 312 rotates upward to clamp the back plate 2, at the same time, the upper plate body 321 and the lower plate body 322 release the clamping of the back plate 2. In the process of the compression roller 4 returning, the sliding block 84 drives the back plate 2 to rise.
