Description

Technical Field

[0001] The present invention belongs to the technical field of solar module production, and in particular relates to a multi-layer lamination device for producing solar modules. Background Art

[0002] The solar panel stacking process is an effective assembly method to improve the efficiency of solar power generation. By stacking multiple solar panels vertically together, the solar energy absorption capacity per unit area can be increased, and the power generation efficiency can be improved to a certain extent. The stacking order is usually cover glass-EVA-cell-EVA-base plate.

[0003] At present, since the solar cell modules may be broken and damaged due to human or equipment reasons after EVA lamination, the damaged laminated solar cell modules need to be inspected and repaired before being sent to the laminator for lamination. Since the battery modules are mostly located in the center of the stacking, the cover glass needs to be removed during maintenance. A suction cup is often used to directly suck and peel off the cover glass. Since the cover glass is directly lifted up and the EVA film underneath is tightly fitted to the cover glass, a partial vacuum space is formed between the two. When the cover glass is directly lifted up, the EVA film is simultaneously lifted up, causing the EVA film to be folded and damaged, or directly dislocated, affecting the normal operation of the assembly line. Summary of the Invention

[0004] The object of the present invention is to provide a multi-layer lamination device for producing solar modules to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a multi-layer lamination device for producing solar panels, comprising a base, a visual inspection component mounted on the bottom of the base, a fixing plate and a support frame fixedly connected to the top of the base, a support assembly for carrying the solar panels mounted on the base, and a lifting frame for lifting a glass cover, disposed above the support assembly, a cylinder hingedly connected to the lower end of the support frame, and a lower end of the cylinder fixedly connected to the lifting frame, and a plurality of suction cups mounted on the bottom of the lifting frame;

[0010] Preferably, the adjustment assembly includes an adjustment plate slidably connected to the base, the adjustment plate is connected to the base through a spring, a pushing assembly is installed on the upper surface of the adjustment plate, one end of the adjustment plate is fixedly connected to a stop block, and the side of the rotating member close to the stop block is fixedly connected to a lower guide plate. When the stop block is located directly above the lower guide plate, the upward movement of the cross bar will cause the rotating member to tilt toward one side of the transfer frame.

[0011] Preferably, the pushing assembly includes a vertical rod fixedly connected to the upper surface of the adjustment plate, and two pushing blocks are fixedly connected to the side of the lifting frame away from the guide rod, and the pushing blocks abut against the vertical rod.

[0012] Preferably, it also includes a feeding component for feeding good solar modules to the top of the base, the feeding component includes an upper guide plate fixedly connected to the side of the rotating member close to the lower guide plate, the upper guide plate is located above the lower guide plate, and the two are separated by a certain height. When the stop block is located directly below the upper guide plate, the downward movement of the cross bar will cause the rotating member to tilt toward the side away from the transfer rack, and the upper surface of the transfer rack is fixedly connected to a loading box, and an automatic dispensing machine for distributing good solar modules is installed in the loading box, the surface outlet of the loading box faces the side of the rotating member, and the surface of the loading box outlet is rotatably connected to a number of loading rollers for guiding solar modules, and the surface of the support frame is fixedly connected to a baffle for positioning solar modules.

[0013] Preferably, a trigger button is installed on the inner wall of the vertical slot, and the trigger button is electrically connected to the automatic dispensing machine.

[0014] Preferably, a return block is fixedly connected to the lower surface of the adjustment plate, and a return dial block adapted to the return block is fixedly connected to the surface of the cross bar, and the opposite surfaces of the return dial block and the return block are both set as arc surfaces.

[0015] Preferably, a U-shaped frame is fixedly connected to the surface of the rotating part, and a positioning plate is rotatably connected to the surface of the U-shaped frame.

[0016] Preferably, the support assembly includes two oppositely placed vertical plates fixedly connected to the inner bottom of the base, and the opposite sides of the two vertical plates are rotatably connected to a plurality of conveying rollers, and the side of the vertical plate away from the conveying roller is rotatably connected to a plurality of synchronous wheels that are respectively axially connected to the conveying rollers, and the surfaces of several of the synchronous wheels are transmission-connected with synchronous belts, and a driving member is also installed on the surface of the vertical plate, and the driving member is transmission-connected to one of the synchronous wheels.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a guide groove, in which the lifting frame slides via a guide rod. Since the guide groove is divided into an oblique groove and a vertical groove, when the lifting frame lifts the glass cover plate via a suction cup, the guide rod moves along the oblique groove, thereby causing the lifting frame to tilt accordingly, and the glass cover plate to tilt synchronously, so that one side of the glass cover plate is first separated from the EVA film, thereby facilitating the destruction of the vacuum adsorption state between the glass cover plate and the EVA film, thereby achieving the effect of improving the effective separation of the glass cover plate and the EVA film and avoiding the occurrence of folding or damage of the EVA film during separation.

[0019] 2. The present invention provides an auxiliary frame that can cooperate with the lifting frame. After the lifting frame moves up and tilts, it overlaps with the auxiliary frame and can pull the auxiliary frame up, thereby causing several groups of switching rollers to lift the defective solar panels. Under the obstruction of the adjustment component, the rotating parts can be rotated and tilted synchronously, so that the defective solar panels can slide outward from the switching rollers, pass through the discharging rollers into the discharging chute, and enter the subsequent rework process outward. Since the glass cover above the solar panel has been lifted by the lifting frame at this time, the step of removing the glass cover is omitted in the subsequent rework process, thereby achieving the effect of simplifying the steps.

[0020] 3. The present invention adopts the arrangement of feeding components. After the defective solar components are fed out, the trigger button is triggered by the lifting frame after returning to the center. At this time, the automatic dispenser in the loading box releases a group of good solar components downward without the top cover glass. The cross bar moves downward simultaneously. During the downward movement, the rotating part is also hindered by the adjustment component, causing the rotating part to tilt in the opposite direction, thereby receiving the fed-in good solar components. Then the cover glass continues to be lowered, and the entire assembly line continues to operate.

[0021] 4. The present invention places the entire device on the production line between the stacking machine and the laminating machine, so that defective products can be detected directly after stacking, eliminating the need for manual inspection and transfer of defective products, as well as the steps of removing the glass cover. After the defective products are sent out, they are immediately replaced with good products and covered with the glass cover, and the operation can continue to send the solar panels into the laminating machine, effectively improving the operation efficiency of the production line.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, an embodiment of the present invention provides a multi-layer stacking device for producing solar modules, including a base 1. The base 1 is in a "U" shape. A visual inspection component 11 is installed at the bottom of the base 1. The visual inspection component 11 is used to detect cracks, defects, foreign matter and other problems in the solar cell panels through a high-speed camera, image recognition technology, etc. A fixing plate 12 and a support frame 13 are fixedly connected to the top of the base 1. The support frame 13 is in an "L" shape. A supporting assembly for carrying the solar module is installed in the base 1, and also includes a lifting frame 41 for lifting the glass cover. The overall size of the lifting frame 41 is comparable to the size of the solar module. It is arranged above the supporting assembly. The lower end of the support frame 13 is hinged with a cylinder 4. The cylinder 4 is powered by an external power source, and the lower end of the cylinder 4 is fixedly connected to the lifting frame 41. Since the cylinder 4 is hinged on the support frame 13, the rotation of the cylinder 4 will drive the lifting frame 41 to rotate synchronously, and a number of suction cups 411 are installed at the bottom of the lifting frame 41.

[0034] Side plates 43 are fixedly connected on both sides of the fixed plate 12, and guide grooves 431 are opened on the opposite sides of the two side plates 43. The lifting frame 41 is connected to the guide grooves 431 through a guide rod 432. One end of the guide rod 432 is fixedly connected to the surface of the lifting frame 41, and the other end slides in the guide groove 431.

[0035] It also includes a removal component for sending out defective solar modules. A transfer rack 2 is provided on one side of the base 1. A discharge chute 21 for passing defective solar modules is provided on the surface of the transfer rack 2. The discharge chute 21 leads to the subsequent maintenance link, and the discharge chute 21 is an inclined chute to facilitate the sliding out of the solar modules. A number of discharge rollers 211 are rotatably connected to the surface of the base 1 to facilitate the passage of defective solar modules.

[0036] Specifically, the suction cup 411 is made of soft material, such as rubber, and is connected to an external air pressure pump through an air tube. After contacting the surface of the cover glass and sticking to it, a negative pressure is formed by evacuating the air in the suction cup 411, thereby adsorbing the cover glass. At the same time, the air pressure pump can be set to an output mode of blowing first and then sucking. Specifically, before the suction cup 411 contacts the glass cover, air is first blown through the air pressure pump, and then sprayed out by the suction cup 411 to blow away debris and dust on the surface of the glass cover to ensure complete and comprehensive contact, and then air is sucked in and the suction cup 411 is adsorbed.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the guide groove 431 is divided into an oblique groove and a vertical groove, and the oblique groove and the vertical groove are connected up and down. A one-way plate 433 is hinged on the surface of the side plate 43 at the intersection of the oblique groove and the lower end of the vertical groove. The one-way plate 433 is connected to the side plate 43 through a torsion spring. The two ends of the torsion spring are fixedly connected to the one-way plate 433 and the side plate 43 respectively. When the torsion spring is relaxed, the one-way plate 433 will block the lower end of the vertical groove. Figure 5 Status shown.

[0038] Specifically, when the cylinder 4 contracts and drives the lifting frame 41 to move upward, the lifting frame 41 slides in the guide groove 431 through the guide rod 432. Since the lower end of the vertical groove is blocked by the one-way plate 433, the guide rod 432 can only enter the inclined groove along the one-way plate 433. The lower end of the inclined groove has a large inclination and is located at the initial stage of the lifting frame 41 lifting the cover glass. Therefore, the lifting frame 41 will tilt with the movement of the guide rod 432, so that one end of it is higher than the other end. The rising end first drives the cover glass to separate from the solar panel, destroying the partial vacuum state between the cover glass and the EVA film. The EVA film at one end first separates from the cover glass, making the subsequent partial separation more convenient and effective, reducing the adhesion of the EVA film to the cover glass.

[0039] Subsequently, when the guide rod 432 moves up to the connecting point of the vertical slot and the upper end of the inclined slot, the guide rod 432 is no longer obstructed, so that the lifting frame 41 returns to the straight position, and the guide rod 432 enters the range of the vertical slot, which is convenient for the subsequent cylinder 4 to drive the lifting frame 41 to move down, and to stabilize and position the cover glass when it is covered. When the guide rod 432 moves down from the top of the vertical slot and passes through the one-way plate 433, the one-way plate 433 can be forced to rotate downward, thereby not hindering the downward movement of the guide rod 432.

[0040] It is worth noting that, since the lifting frame 41 is in an inclined state during the upward movement, it is also convenient for dust and dirt on the surface of the cover glass to fall off.

[0041] like Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the removal component includes an auxiliary frame 5, which is arranged above the base 1, and the auxiliary frame 5 is connected to the support frame 13 through a gas rod 51. The upper end of the gas rod 51 is fixedly connected to the support frame 13, and the lower end of the gas rod 51 is fixedly connected to the auxiliary frame 5. The upper end of the auxiliary frame 5 is "L"-shaped. When the lifting frame 41 is in a horizontal state, the upper end of the auxiliary frame 5 does not overlap with the lifting frame 41 in the vertical direction. At this time, the auxiliary frame 5 will not contact the lifting frame 41, and the auxiliary frame 5 will not move up. The front and rear sides of the base 1 are fixedly connected to the guide rails 52, and the auxiliary frame 5 is connected to the guide rails 52 through a slider 521. The upper end of the slider 521 is fixedly connected to the auxiliary frame 5, and the slider 52 The lower end of the auxiliary frame 5 slides in the guide rail 52, and both arm ends of the auxiliary frame 5 are fixedly connected to the cross bar 53, which is arranged horizontally. The end of the cross bar 53 away from the auxiliary frame 5 is fixedly connected to the positioning shaft 532. The surface of the positioning shaft 532 is rotatably connected to a rotating member 533. The rotating member 533 is connected to the cross bar 53 through a torsion spring A534. The two ends of the torsion spring A534 are fixedly connected to the rotating member 533 and the cross bar 53 respectively. The two arm ends of the rotating member 533 are rotatably connected to the switching roller 535. The switching roller 535 is used to directly contact the bottom of the solar module. An adjustment component for rotating the rotating member 533 along the positioning shaft 532 is installed on the side of the base 1 close to the auxiliary frame 5.

[0042] Specifically, under normal conditions, the gas rod 51 is in a relaxed state, and the auxiliary frame 5 is at the bottom position. At this time, the height of the switching roller 535 is not higher than the lowest position of the solar panel, and the switching roller 535 does not contact the solar panel. After the cylinder 4 contracts to move the lifting frame 41 upward and tilt, the lifting frame 41 will overlap with the upper end of the auxiliary frame 5 in a vertical position due to the tilt. Therefore, during the upward movement of the lifting frame 41, it will contact the upper end of the auxiliary frame 5, thereby driving the auxiliary frame 5 to move upward and compressing the gas rod 51, prompting the lower switching roller 535 to move upward to lift the solar panel.

[0043] Furthermore, in this embodiment, the adjustment assembly includes an adjustment plate 6 that is slidably connected to the base 1. The adjustment plate 6 is connected to the base 1 through a spring 64. The two ends of the spring 64 are fixedly connected to the adjustment plate 6 and the base 1 respectively. A pushing assembly is installed on the upper surface of the adjustment plate 6. One end of the adjustment plate 6 is fixedly connected to a stop block 62. The side of the rotating member 533 close to the stop block 62 is fixedly connected to a lower guide plate 536. When the stop block 62 is located directly above the lower guide plate 536, the upward movement of the cross bar 53 will cause the rotating member 533 to tilt toward one side of the transfer rack 2.

[0044] Specifically, it is mentioned above that the switching roller 535 lifts the solar panel to a certain height as the auxiliary frame 5 moves upward. During the upward movement of the rotating member 533, when the lower guide plate 536 encounters the restriction of the block 62, the rotating member 533 located on the side of the block 62 cannot move upward, but the auxiliary frame 5 is still moving upward, so the rotating member 533 will rotate accordingly on the positioning shaft 532 and compress the torsion spring A534, and the entire rotating member 533 will tilt in the direction of the auxiliary frame 5. Due to the tilt of the rotating member 533, the solar panel on the surface of the switching roller 535 slides outward under the influence of gravity until it passes through the discharging roller 211 and enters the discharging chute 21, and then enters the next manual maintenance link. Note that at this time the cover glass has been uncovered as the lifting frame 41 moves upward, and maintenance can be carried out directly without uncovering the cover glass.

[0045] Furthermore, in this embodiment, the pushing assembly includes a vertical rod 61 fixedly connected to the upper surface of the adjustment plate 6 , and two pushing blocks 42 are fixedly connected to the side of the lifting frame 41 away from the guide rod 432 , and the pushing blocks 42 abut against the vertical rod 61 .

[0046] Specifically, when the lifting frame 41 tilts, the pushing block 42 on one side of the lifting frame 41 will correspondingly push the vertical rod 61, thereby causing the adjustment plate 6 to slide toward the side away from the rotating part 533 and compress the spring 64. At this time, the adjustment plate 6 drives the stop block 62 to move to a position above the lower guide plate 536, so as to facilitate subsequent blocking of the lower guide plate 536.

[0047] Furthermore, in one embodiment, it also includes a feeding component for feeding good solar modules to the top of the base 1, and the feeding component includes an upper guide plate 537 fixedly connected to the rotating member 533 near the lower guide plate 536 side, the upper guide plate 537 is located above the lower guide plate 536, and the two are spaced at a certain height, and the length of the lower guide plate 536 is greater than the length of the upper guide plate 537. When the stop block 62 is directly below the upper guide plate 537, the downward movement of the cross bar 53 will cause the rotating member 533 to tilt toward the side away from the transfer rack 2, and the upper surface of the transfer rack 2 is fixedly connected to a loading box 22, and an automatic dispensing machine for distributing good solar modules is installed in the loading box 22. The automatic dispensing machine is a dispensing system with multi-layer placement space and a single triggering by a trigger mechanism. It is a prior art. The surface outlet of the loading box 22 faces the side of the rotating member 533, and the outlet surface of the loading box 22 is rotatably connected to a number of loading rollers 221 for guiding solar modules, and the surface of the support frame 13 is fixedly connected to a baffle 14 for positioning solar modules.

[0048] Specifically, since the upper guide plate 537 and the lower guide plate 536 are placed separately, when the stopper 62 abuts against the lower guide plate 536 and causes the rotating member 533 to rotate and tilt toward one side of the auxiliary frame 5, during this process, after the guide rod 432 on the surface of the lifting frame 41 moves to the top of the guide groove 431, the guide rod 432 is no longer hindered, and the lifting frame 41 is then returned to the center position from the tilted state, and at the same time, under the action of the rebound force of the spring 64, the adjustment plate 6 is synchronously returned to the center position, and is now located on the lower guide plate 536. The stopper 62 will move forward and get stuck under the upper guide plate 537, thereby blocking the downward movement of the upper guide plate 537. Since the lifting frame 41 is no longer in contact with the auxiliary frame 5 after returning to the center, the auxiliary frame 5 moves downward under the rebound of the gas rod 51. At this time, the upper guide plate 537 blocked by the stopper 62 will prompt the rotating part 533 in the downward state to rotate in the opposite direction and rotate and tilt toward the side away from the auxiliary frame 5. At this time, the reversely tilted rotating part 533 is convenient for receiving the good solar panels led out from the loading box 22.

[0049] A trigger button 434 is installed on the inner wall of the vertical slot. The trigger button 434 is a push-type button and is electrically connected to the automatic dispensing machine.

[0050] It should be noted that, since the trigger button 434 is disposed on the inner wall of the vertical slot, Figure 5 As shown, in the process of the guide rod 432 passing over the top of the inclined groove and returning to the center, the guide rod 432 will contact the trigger button 434. After being triggered, the automatic dispensing machine located in the loading box 22 will automatically send down a group of good solar modules. The good solar modules located in the loading box 22 do not have a top glass cover. The defective solar modules after repair can also be placed in the automatic dispensing machine for distribution. The solar modules sent out from the distribution opening of the loading box 22 will be guided by the loading roller 221 and sent to the surface of the reversely inclined switching roller 535, and will be limited by the baffle 14, so that the good solar modules at this time are sent directly below the glass cover.

[0051] Furthermore, in this embodiment, a return block 63 is fixedly connected to the lower surface of the adjustment plate 6, and a return dial block 531 adapted to the return block 63 is fixedly connected to the surface of the cross bar 53. The opposite surfaces of the return dial block 531 and the return block 63 are both set to arc surfaces. When the cross bar 53 moves downward with the auxiliary frame 5 and makes the return dial block 531 contact with the return block 63, the return dial block 531 is pushed by the force of the air rod 51 continuing to move downward, and drives the adjustment plate 6 to move horizontally a certain distance toward the side away from the rotating member 533, thereby helping the block 62 to disengage from the upper guide plate 537. After disengagement, under the action of the rebound force of the torsion spring A534, the rotating member 533 will return to the center, preventing the switching roller 535 from continuing to abut against the solar panel.

[0052] Among them, the surface of the rotating part 533 is fixedly connected to the U-shaped frame 54, and the surface of the U-shaped frame 54 is rotatably connected to the positioning plate 541. A torsion spring B542 is provided at the hinge axis of the positioning plate 541 and the U-shaped frame 54. The two ends of the torsion spring B542 are respectively fixedly connected to the positioning plate 541 and the U-shaped frame 54. A limiting plate 543 adapted to the positioning plate 541 is fixedly connected to the bottom of the base 1. Under normal conditions, when the torsion spring B542 is in a relaxed state, the positioning plate 541 is in a horizontal state.

[0053] Specifically, when the auxiliary frame 5 drives the rotating member 533 to move downward and moves the positioning plate 541 to the position of the limit plate 543, the positioning plate 541 will rotate upward accordingly due to the obstruction of the limit plate 543 and abut against the side of the good solar panel that has just been delivered to position the good solar panel. Under the joint positioning of the two positioning plates 541, the positioning of the solar panel is more accurate, ensuring a tight fit after the glass cover is lowered.

[0054] The supporting assembly includes two oppositely placed vertical plates 3 fixedly connected to the bottom of the base 1, and the opposite sides of the two vertical plates 3 are rotatably connected to a number of conveying rollers 31. The conveying rollers 31 are used to support and convey the stacked solar panels. The side of the vertical plate 3 away from the conveying roller 31 is rotatably connected to a number of synchronous wheels axially connected to the conveying rollers 31 respectively. The surfaces of the several synchronous wheels are transmission-connected with synchronous belts 311. Through the action of the synchronous belts 311, the several conveying rollers 31 can rotate synchronously. A driving member 32 is also installed on the surface of the vertical plate 3, and the driving member 32 is transmission-connected to one of the synchronous wheels. Here, the driving member 32 can be a servo motor and a reducer. The output end of the servo motor is decelerated by the reducer and then transmission-connected to one of the synchronous wheels, which is used to drive multiple groups of conveying rollers 31 to rotate.

[0055] Working principle:

[0056] The stacked solar panels are delivered to the top of the base 1 through the front stacking assembly line, and are transported to the top of the bottom visual inspection part 11 for inspection through the conveying roller 31. If the inspection is defective, the cylinder 4 outputs the air to drive the lifting frame 41 to move down, so that the suction cup 411 forms a negative pressure and adsorbs on the surface of the top cover glass. Then the cylinder 4 contracts and drives the lifting frame 41 to move up. Under the guidance of the inclined groove on the guide rod 432, the lifting frame 41 will gradually tilt while moving up. At this time, the push block 42 will push the vertical rod 61 on one side, so that the adjustment plate 6 is moved away from the rotating part 53. 3 slides on one side and compresses the spring 64. The inclined lifting frame 41 will lift one side of the cover glass first, and the EVA film on one side will be separated from the cover glass first. Then, the lifting frame 41 will simultaneously lift the auxiliary frame 5 while continuing to move upward. The auxiliary frame 5 drives the cross bar 53 to move upward, and the rotating member 533 drives the switching roller 535 to lift the solar module after the glass cover is peeled off. Then, under the obstruction of the block 62, the rotating member 533 tilts and causes the solar module to slide down, pass through the discharge roller 211, enter the discharge chute 21, and then be discharged to the subsequent maintenance link.

[0057] After the cylinder 4 drives the lifting frame 41 to move upward and the guide rod 432 passes the top of the inclined slot, the lifting frame 41 returns to its original position under the action of gravity, so that the guide rod 432 enters the vertical slot and the trigger button 434 is pressed. At this time, the automatic dispenser in the loading box 22 sends out a group of good solar panels. In this process, due to the return of the lifting frame 41, the adjustment plate 6 returns to its original position under the rebound force of the spring 64, so that the stopper 62 is stuck under the upper guide plate 537, and the auxiliary frame 5 is no longer affected by the upward movement of the lifting frame 41. Under the rebound action of the gas rod 51, the auxiliary frame 5 moves downward, and the rotating member 533 moves downward synchronously. The upper guide plate 537 is blocked by the block 62, causing the rotating part 533 to rotate in the opposite direction, thereby receiving a group of good solar modules sent from the loading box 22 into the top of the base 1. The good solar modules are stopped by the limiting action of the baffle 14. During the continued downward movement of the auxiliary frame 5, the return block 531 drives the return block 63 to disengage the block 62 from the upper guide plate 537, thereby returning the rotating part 533 to the center. Then the cylinder 4 outputs, causing the lifting frame 41 to drive the glass cover to cover the top of the good solar modules. After being inspected again by the visual inspection part 11 and found to be correct, it is sent to the next laminator.
