Description

[Technical field]

[0001] The invention belongs to the technical field of photovoltaic module production, and in particular relates to a butyl rubber pad plugging device for photovoltaic heterojunction modules. [Background technology]

[0002] In the production process of photovoltaic modules, there will be a gap in the EVA film at the lead position for the lead to pass through and expose. In order to fill the gap on the EVA film, conventional photovoltaic modules usually use butyl rubber pads to cover this gap to prevent the melt from being squeezed out of the gap after the film melts during the lamination process. For example, in the prior art, a photovoltaic module butyl rubber pad placement labeling integrated device and process method disclosed in Chinese Patent Publication No. CN 115557043A is first straightened, and then the insulating small block is placed on the lead to fill the gap on the EVA film. However, for heterojunction modules, in addition to filling the gap on the EVA film, the gap is also required to have sealing and waterproof properties, but conventional insulating small blocks cannot achieve sealing and waterproof effects, so a butyl rubber pad with stickiness is used, the butyl rubber pad is sleeved on the lead, and the bottom of the butyl rubber pad is bonded to the surface of the heterojunction module to block the gap and achieve sealing and waterproof properties at the gap. Since the butyl rubber pad is sticky, if the feeding method of the photovoltaic module butyl rubber pad placement and labeling integrated equipment and process method disclosed in Chinese Patent Publication No. CN 115557043A is adopted, the butyl rubber pad will stick to the feeding device and the conveyor line, resulting in the inability to smoothly place the butyl rubber pad on the lead, reducing the production yield and thus reducing the production efficiency.

[0003] Therefore, it is necessary to provide a photovoltaic heterojunction module butyl rubber gasket plugging device to solve the above technical problems. [Summary of the invention]

[0046] The component conveying device 1 includes a conveying line 11 for conveying components, a plurality of support wheels 12 arranged in the middle of the conveying line 11 and supporting the components, a blocking component 13 arranged at the front end of the conveying line 11 and blocking the components from continuing to be conveyed forward, a first correcting component 14 for correcting the rear end of the component, a pair of second correcting components 15 for correcting the other two opposite sides of the component, and a fifth motor 16 for driving the pair of second correcting components 15 to move closer to or away from each other.

[0047] Several support wheels 12 are arranged along the extension direction of the lead of the component.

The material of the tray 26 is an anti-sticking material, for example, the material of the side of the tray 26 is polytetrafluoroethylene, or other anti-sticking materials, which are not limited here; since the sticky layer of the butyl rubber pad faces downward, the material of the tray 26 is an anti-sticking material, which can prevent the butyl rubber pad from adhering to the tray 26.

[0049] The transfer module 23 includes a transfer plate 231 and a first Y-axis driving module 232 for driving the transfer plate 231 to move along the Y direction. A first avoidance opening 233 is provided in the middle of the transfer plate 231. A lifting module 234 is provided in the first avoidance opening 233. The lifting module 234 includes a support frame 2341 fixed on the lower surface of the transfer plate 231, a lifting cylinder 2342 provided on the support frame 2341, and a lifting plate 2343 driven by the lifting cylinder 2342 to move up and down in the first avoidance opening 233.

A connecting block 2325 connected to the transmission belt 2324 is provided on the lower surface of the transfer plate 231. In order to ensure the stability of the movement of the transfer plate 231, two parallel optical axis guide rails 2326 are provided below the transfer plate 231. The transfer plate 231 is slidably set on the optical axis guide rails 2326 through a slider 2327.

[0051] The separation assembly 24 includes a separation plate 241 for separating the bottommost material tray 26 from the penultimate material tray 26 on the storage bin 21 and a separation cylinder 242 for driving the separation plate 242 to extend or retract. When the transfer module 23 is located at the material picking station, the separation plate 241 supports the multi-layer material tray 26. After the material picking station, the transfer module 23 will move to the material discharging station to pick up a new material tray 26. The lifting module 234 lifts the multi-layer material tray 26 upward and supports the material tray. The separation cylinder 242 drives the separation plate 241 to retract. The lifting module 234 drives the multi-layer material tray 26 to descend into place. The separation cylinder 242 drives the separation plate 241 to extend so that the separation plate 241 is inserted between the bottom material tray 26 and the second to last material tray 26. The separation plate 241 supports the second to last and the upper material trays 26. The lifting module 234 drives the bottom material tray 26 to continue to descend so that the material tray is carried on the transfer plate 231, so that the bottom material tray 26 is separated from the upper material tray 26. The first Y-axis drive module 232 drives the transfer plate 231 to move to the material picking station to wait for the material picking operation.

[0052] The support assembly 25 includes a support seat 251 and a support block 252 rotatably disposed on the support seat 251. When the lifting module 234 drives the empty tray to move to the recovery station, the lifting module 234 pushes the empty tray upward, and at the same time, the side of the tray drives the support block 252 to rotate upward. When the bottom layer of tray is higher than the support block 252, the support block 252 rotates downward to maintain a horizontal state, and then the lifting module 234 drives the empty tray to move downward so that the empty tray is supported on the support block 252.

[0053] The transfer conveying platform 3 includes a first carrier plate 31 and a second carrier plate 32 that are movably arranged along the X direction to realize alternating work, a first driving member 33 that drives the first carrier plate 31 to move along the X direction, a second driving member 34 that drives the second carrier plate 32 to move along the X direction, and a cam mechanism 35 that drives the second carrier plate 32 to move up and down. The first carrier plate 31, the second carrier plate 32, the first driving member 33, the second driving member 34 and the cam mechanism 35 are jointly arranged on a base 39, the first driving member 33 and the second driving member 34 are arranged on the front and rear sides of the base 39, the first carrier plate 31 is arranged on the upper end of the base 39 through a slide rail slider, and the left and right ends of the base 39 are provided with second sensors to detect whether the first carrier plate 31 and the second carrier plate 32 have moved into place.

[0054] A plurality of carriers 36 are disposed on the first carrier plate 31 and the second carrier plate 32. In this embodiment, three carriers 36 are disposed on the first carrier plate 31 and the second carrier plate 32. The carrier 36 is provided with a receiving groove 37 for placing the butyl rubber pad. The receiving groove 37 is provided with a profiling pin 38. The profiling pin 38 can facilitate accurate positioning of the butyl rubber pad so as to accurately place the butyl rubber pad on the lead of the component. The material of the carrier 36 is an anti-sticking material, for example, the material of the carrier 36 is polytetrafluoroethylene, or other anti-sticking materials, which are not limited here. Since the adhesive layer of the butyl rubber pad faces downward, the material of the carrier 36 is an anti-sticking material, which can prevent the butyl rubber pad from adhering to the carrier 36.

[0055] Since the first carrier plate 31 and the second carrier plate 32 work alternately, the first carrier plate 31 and the second carrier plate 32 are at the same height when receiving materials at the leftmost end and unloading materials at the right end. However, after the first carrier plate 31 and the second carrier plate 32 move alternately left and right, they need to avoid up and down to exchange positions left and right. Therefore, in this embodiment, a cam mechanism 35 is provided to drive the second carrier plate 32 to move up and down. In other embodiments, the cam mechanism 35 can also drive the first carrier plate 31 to move up and down, which is not limited here. The cam mechanism 35 includes a first moving block 351 fixed to the lower surface of the second carrier plate 32, a roller 352 fixed to the lower end of the first moving block 351, and a rolling track 353 arranged along the X direction for the roller 352 to move. The two ends of the rolling track 353 are at a high position and the middle is at a low position. The height of the rolling track 353 gradually decreases from the two ends to the middle. When the roller 352 is at a high position at the two ends, the second carrier plate 32 and the first carrier plate 31 are translated in height. When the roller 352 moves from the two ends to the middle, the second carrier plate 32 descends to avoid the first carrier plate 31. In order to ensure the stability of the left and right movement of the second carrier plate 32, a plurality of guide rods 354 are arranged at the lower end of the second carrier plate 32. The plurality of guide rods 354 are installed on the moving plate 355 through linear bearings. The moving plate 355 is located below the second carrier plate 32. A slide rail is arranged inside the base 39. The moving plate 355 is movably arranged on the slide rail through a slider.

[0056] The conveying mechanism 4 includes an XY-axis driving module 41, a vertical plate 42 driven by the XY-axis driving module 41 to move along the XY direction, and a plurality of adsorption conveying units 43 arranged on the vertical plate 42 and working independently of each other. In this embodiment, three adsorption conveying units 43 are arranged, which can simultaneously convey three butyl rubber pads. Since the spacing between the material storage slots on the material tray 26 is very small, if the three adsorption conveying units adsorb at the same time, they will interfere with each other and cannot take materials. Each adsorption conveying unit 43 is arranged to work independently of each other, and only one adsorption conveying unit 43 extends into the material tray 26 to take materials at a time, which can adapt to the material tray 26 with a very small spacing between the material storage slots.

[0057] The adsorption and transport unit 43 includes a first motor 431 disposed on the vertical plate 42, a first lifting block 432 driven by the first motor 431 to move up and down, a first ball spline shaft module 433 rotatably disposed on the first lifting block 432 and moving up and down simultaneously with the first lifting block 432, a second motor 434 driving the first ball spline shaft module 433 to rotate, a first adsorption mounting block 435 disposed at the lower end of the first ball spline shaft module 433, and a plurality of first suction cups disposed at the bottom of the first adsorption mounting block 435. A first avoidance groove for avoiding the profiling pin 38 is disposed at the bottom of the first adsorption mounting block 435, and a plurality of first suction cups are disposed at the periphery of the first avoidance groove.

[0058] The first ball spline shaft module 433 includes a ball spline shaft, a spline nut and a ball screw nut. The ball spline shaft is provided with a vertical rolling groove. The first ball spline shaft module 433 is a prior art and will not be described in detail here.

[0059] In this embodiment, the first motor 431 is arranged above the second motor 434, and the first motor 431 and the second motor 434 are both arranged on the back of the vertical plate 42. The output shaft ends of the first motor 431 and the second motor 434 are both connected to a synchronous pulley set. The two sets of synchronous pulley sets respectively drive the first ball spline shaft module 433 to move up and down or rotate, thereby removing the butyl rubber pad or rotating the butyl rubber pad. The direction of the butyl rubber pad can be changed, and it can adapt to leads in different directions.

[0060] The XZ-axis driving module 5 includes a pair of X-axis driving modules 51 arranged front and back, a moving beam 52 driven by the X-axis driving module 51 to move along the X direction, and a Z-axis driving motor 53 arranged on the moving beam 52. A moving support plate is arranged at the output end of the Z-axis driving motor 53, and the mounting beam 6 is arranged on the moving support plate.

[0061] In the present embodiment, there are three places on the component where butyl rubber pads need to be placed on the leads. Correspondingly, three transporting and placing units 7 are provided. The pick-up and placement mechanisms 71 of the three transporting and placing units 7 simultaneously pick up and place the three butyl rubber pads, and the three lead straightening mechanisms 72 simultaneously complete the straightening of the leads. In order to improve the versatility of the transporting and placing units 7, the three transporting and placing units 7 are movably arranged on the mounting beam 6 along the Y direction, and can adapt to photovoltaic components of different sizes, so that the pick-up and placement mechanisms 71 can adapt to butyl rubber pads at different positions and leads at different positions, so that the lead straightening mechanisms 72 can straighten the leads at different positions. Therefore, the transporting and placing unit 7 also includes a second Y-axis driving module 74 arranged on the mounting beam 6, and a mounting frame 75 driven by the second Y-axis driving module 74 to move along the Y direction.

No matter the leads are bent inward or outward, the two leads enter the corresponding first avoidance groove 7244 respectively, so that the leads can be straightened. Moreover, the left straightening component 724 and the right straightening component 725 are staggered up and down so that different height positions of the leads can be straightened at the same time, and leads in various bending states can be straightened more accurately, thereby improving the quality of lead straightening, so that the butyl rubber pad can be accurately placed on the leads.

[0069] When the photovoltaic heterojunction component butyl rubber pad plugging device 100 provided by the present solution is applied, after the component is input into place from the conveyor line 11, the blocking component 13 blocks the component from continuing to be conveyed forward, the first correcting component 14 corrects the rear end of the component, and the fifth motor 16 drives the second correcting component 15 to approach each other to correct the two opposite sides of the component, thereby completing the correction of the component on all sides; at the same time, the transfer module 23 moves to the material picking station, the lifting module 234 lifts the multi-layer material tray 26 upward and supports the material tray, the separation cylinder 242 drives the separation plate 241 to retract, the lifting module 234 drives the multi-layer material tray 26 to descend into place, and the separation cylinder 242 drives the separation plate 241 to extend so that the separation plate 241 is inserted into the bottommost material tray 26 and the second to last material tray 26, the separation plate 241 supports the second to last and the upper material tray 26, the lifting module 234 drives the bottom material tray 26 to continue to descend so that the material tray is carried on the transfer plate 231, so that the bottom material tray 26 is separated from the upper material tray 26, the first Y-axis driving module 232 drives the transfer plate 231 to move to the material picking station, the XY-axis driving module 41 drives the three adsorption and conveying units 43 to move to the material picking station, the three adsorption and conveying units 43 are successively extended into the material tray 26 to pick up materials, the first motor 431 drives the first ball spline shaft module 433 to descend to the material tray 26 to pick up materials, and after the three adsorption and conveying units 43 have absorbed the butyl rubber pad, the XY-axis driving module 41 drives the three adsorption and conveying units 43 to move to the transfer station.

The left straightening component 724 and the right straightening component 725 are driven simultaneously or successively by the straightening cylinders 7241, so that the two straightening plates 7243 are extended simultaneously or successively and inserted between the two leads, so that the lead wire enters the third avoidance groove 7244, so that the lead wire becomes vertical.The third motor 711 drives the second lifting block 712 to drive the second ball spline shaft module 713 to descend, so that the second suction cup descends, and the butyl rubber pad is accurately sleeved on the upper end of the lead wire. The straightening cylinders 7241 of the left straightening assembly 724 and the right straightening assembly 725 are driven at the same time, so that the two straightening plates 7243 are retracted at the same time. The third motor 711 continues to drive the second lifting block 712 to drive the second ball spline shaft module 713 to descend, so that the butyl rubber pad continues to descend and is sleeved on the bottom of the lead wire, so that the butyl rubber pad is completely bonded to the notch of the lead wire. After forming a seal, the straightening of the lead wire and the placement of the butyl rubber pad are completed, the slide cylinder 722 drives the second support plate 723 to rise to its position, and the visual inspection camera 73 takes photos of the lead wire and the butyl rubber pad after the butyl rubber pad is placed to confirm whether the butyl rubber pad is placed properly.
