Description

Technical field

[0001] The utility model belongs to the technical field of photovoltaic component production, in particular to a butyl rubber pad plugging device for photovoltaic heterojunction components. [Background Technology]

[0002] In the production process of photovoltaic modules, there is a gap in the EVA film at the lead position for the lead to pass through and be exposed. 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, Chinese Patent Publication No. CN 115557043A discloses a photovoltaic module butyl rubber pad placement and labeling integrated device and process method, which first straightens the lead, then places a small insulating block on the lead, and fills the gap on the EVA film. However, for heterojunction modules, in addition to filling the gap on the EVA film, the gap also needs to have sealing and waterproof properties, but conventional insulating blocks cannot achieve sealing and waterproof effects, so a butyl rubber pad with stickiness is used, the butyl rubber pad is put 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. Because butyl rubber pads are 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 used, the butyl rubber pads will stick to the feeding device and conveyor line, resulting in the inability to smoothly place the butyl rubber pads on the leads, reducing the production yield and thus reducing production efficiency.

[Specific implementation method]

[0045] Please refer to Figures 1-11 The present embodiment is a photovoltaic heterojunction module butyl rubber pad plugging device 100, a photovoltaic heterojunction module butyl rubber pad plugging device 100 includes a component conveying device 1, a butyl rubber pad feeding device 2 and a transfer conveying platform 3 located on one side of the component conveying device 1, a conveying mechanism 4 for conveying the butyl rubber pads on the butyl rubber pad feeding device 2 to the transfer conveying platform 3, and a conveying and placing device 80 located above the component conveying device 1, the conveying and placing device 80 includes an XZ-axis driving module 5, a mounting beam 6 driven by the XZ-axis driving module 5 to move along the XZ direction, and a plurality of conveying and placing units 7 movably arranged on the mounting beam 6, the conveying and placing unit 7 includes a pick-up and placement mechanism 71 for sucking and placing the butyl rubber pads, a lead straightening mechanism 72 for straightening the leads on the component, and a visual inspection camera 73.

[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 preventing 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 component leads. When the handling and placement unit 7 straightens the leads and places the butyl rubber pads, several support wheels 12 support the back of the component to prevent the component from bending and affecting the accuracy of the placement of the butyl rubber pads. The blocking component 13 includes a blocking cylinder 131 and a blocking wheel 132 driven by the blocking cylinder to move up and down. The first alignment component 14 includes a first alignment cylinder 141 and a first alignment wheel 142 driven by the first alignment cylinder 141 to move up and down. The second alignment component 15 includes a second alignment wheel 151 and a alignment moving block 152 on which the second alignment wheel 151 is installed. The fifth motor 16 drives the alignment moving block 152 to move along the X direction.

[0048] The butyl rubber pad feeding device 2 includes a storage bin 21 located at the discharge station, a tray recovery bin 22 located at the recovery station, and a transfer module 23 for transferring trays 26 between the discharge, recovery, and retrieval stations. A pair of separation assemblies 24 are positioned on opposite sides of the storage bin 21 to separate the bottom tray 26 from the next-to-last tray 26. A pair of support assemblies 25 are positioned on opposite sides of the tray recovery bin 22 to support empty trays. Both the storage bin 21 and the tray recovery bin 22 are equipped with a first sensor for detecting the height of the tray 26. Tray 26 is provided with a storage trough for accommodating the butyl rubber pads. Tray 26 is made of a non-stick material, such as polytetrafluoroethylene (PTFE), but other non-stick materials are also possible, without limitation. Since the adhesive layer of the butyl rubber pad faces downward, the non-stick material of tray 26 prevents 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 that drives 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, and 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 positioning pin for positioning the material tray is provided on the upper surface of the transfer plate 231.

[0050] The first Y-axis driving module 232 includes a driving wheel 2321 and a driven wheel 2322 arranged relative to each other in the front and rear, and a servo motor 2323 that drives the driving wheel 2321 to rotate. The driving wheel 2321 and the driven wheel 2322 realize rotation transmission through a transmission belt 2324. The lower surface of the transfer plate 231 is provided with a connecting block 2325 connected to the transmission belt 2324. 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. 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, thereby realizing the separation of the bottom material tray 26 from the upper material tray 26, and the first Y-axis drive module 232 drives the transfer plate 231 to move to the material taking station for the material taking operation.

[0052] The support assembly 25 includes a support base 251 and a support block 252 rotatably mounted on the support base 251. When the lifting module 234 drives the empty tray to the recycling station, the lifting module 234 pushes the empty tray upward while the side of the tray drives the support block 252 to rotate upward. When the bottom tray is higher than the support block 252, the support block 252 rotates downward to maintain a horizontal state. The lifting module 234 then drives the empty tray downward so that the empty tray is supported on the support block 252.

[0053] The transfer and conveying platform 3 includes a first carrier plate 31 and a second carrier plate 32 that are movable along the X-direction for alternating operation, a first drive member 33 that drives the first carrier plate 31 in the X-direction, a second drive member 34 that drives the second carrier plate 32 in the X-direction, and a cam mechanism 35 that drives the second carrier plate 32 up and down. The first carrier plate 31, the second carrier plate 32, the first drive member 33, the second drive member 34, and the cam mechanism 35 are collectively arranged on a base 39. The first drive member 33 and the second drive member 34 are arranged on the front and rear sides of the base 39. The first carrier plate 31 is mounted on the upper end of the base 39 via a slide block. Second sensors are provided on both the left and right ends of the base 39 to detect whether the first and second carrier plates 31, 32 have moved into position.

[0054] Both the first carrier plate 31 and the second carrier plate 32 are provided with a plurality of carriers 36. In this embodiment, three carriers 36 are provided on each of the first carrier plate 31 and the second carrier plate 32. Each carrier 36 is provided with a receiving groove 37 for butyl rubber pads. Each groove 37 is provided with a contoured pin 38. The contoured pin 38 facilitates precise positioning of the butyl rubber pads, allowing them to be accurately placed on the leads of the component. The carriers 36 are made of a non-stick material, such as polytetrafluoroethylene, but other non-stick materials are also possible and are not limited here. Since the adhesive layer of the butyl rubber pads faces downward, the non-stick material of the carriers 36 prevents the butyl rubber pads 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 movable block 351 fixed to the lower surface of the second carrier plate 32, a roller 352 fixed to the lower end of the first movable block 351, and a rolling track 353 arranged along the X direction for the movement of the roller 352. The rolling track 353 is at a high position at both ends and a low position in the middle. The height of the rolling track 353 gradually decreases from the ends to the middle. When the roller 352 is at a high position at both ends, the second carrier plate 32 and the first carrier plate 31 move horizontally. When the roller 352 moves from the ends to the middle, the second carrier plate 32 descends to avoid the first carrier plate 31. To ensure the stability of the left and right movement of the second carrier plate 32, a plurality of guide rods 354 are provided at the lower end of the second carrier plate 32. The plurality of guide rods 354 are mounted on a movable plate 355 via linear bearings. The movable plate 355 is located below the second carrier plate 32. A slide rail is provided inside the base 39, and the movable plate 355 is movably mounted on the slide rail via 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 provided, which can simultaneously convey three butyl rubber pads. Since the spacing between the 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 the material. Each adsorption conveying unit 43 is set to work independently of each other, and only one adsorption conveying unit 43 extends into the material tray 26 to take the material at a time, which can adapt to the material tray 26 with a very small spacing between the storage slots.

[0057] The suction and transport unit 43 includes a first motor 431 mounted on the vertical plate 42, a first lifting block 432 driven by the first motor 431 for vertical movement, a first ball spline shaft module 433 rotatably mounted on the first lifting block 432 and moving up and down simultaneously with the first lifting block 432, a second motor 434 driving the rotation of the first ball spline shaft module 433, a first suction mounting block 435 mounted at the lower end of the first ball spline shaft module 433, and a plurality of first suction cups mounted at the bottom of the first suction mounting block 435. A first avoidance groove is provided at the bottom of the first suction mounting block 435 to avoid the profiling pins 38, and a plurality of first suction cups are arranged around 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 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 drive module 5 includes a pair of X-axis drive modules 51 arranged in front and behind, a moving beam 52 driven by the X-axis drive module 51 to move along the X direction, and a Z-axis drive motor 53 arranged on the moving beam 52. The output end of the Z-axis drive motor 53 is provided with a moving support plate, and the mounting beam 6 is provided on the moving support plate.

[0061] In this embodiment, there are three leads on the component that require butyl rubber pads to be placed. Correspondingly, three transporting and placing units 7 are provided. The pick-up and placement mechanisms 71 of the three transporting and placement 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 placement units 7, the three transporting and placement 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 mechanism 71 can adapt to butyl rubber pads in different positions and leads in different positions, so that the lead straightening mechanism 72 can straighten the leads in different positions. Therefore, the transport and placement unit 7 also includes a second Y-axis drive module 74 arranged on the mounting beam 6, and a mounting frame 75 driven by the second Y-axis drive module 74 to move along the Y direction. The pick-up and placement mechanism 71, the lead straightening mechanism 72 and the visual inspection camera 73 are all arranged on the mounting frame 75. The set second Y-axis drive module 74 can drive the mounting frame 75 to move along the Y direction, which is sufficient to adapt to photovoltaic modules of different sizes, can take and place butyl rubber pads in different positions, and can also straighten the leads in different positions.

[0062] The pick-and-place mechanism 71 includes a third motor 711 mounted on a mounting frame 75, a second lifting block 712 driven by the third motor 711 for vertical movement, a second ball spline shaft module 713 rotatably mounted on the second lifting block 712 and moving up and down simultaneously with the second lifting block 712, a fourth motor 714 that drives the second ball spline shaft module 713 for rotation, a second suction mounting block 715 mounted at the lower end of the second ball spline shaft module 713, and a plurality of second suction cups mounted at the bottom of the second suction mounting block 715.

[0064] In this embodiment, the third motor 711 is arranged above the fourth motor 714, and the third motor 711 and the fourth motor 714 are both arranged on the back of the mounting frame 75. The output shaft ends of the third motor 711 and the fourth motor 714 are both connected to a synchronous pulley set, and the two sets of synchronous pulley sets respectively drive the second ball spline shaft module 713 to move up and down or rotate, thereby removing the butyl rubber pad or rotating the butyl rubber pad; the fourth motor 714 drives the second ball spline shaft module 713 to rotate to change the direction of the butyl rubber pad, and can adapt to leads in different directions.

[0065] The lead straightening mechanism 72 includes a first support plate 721 arranged at the bottom of the mounting frame 75, a slide cylinder 722 arranged on the first support plate 721, a second support plate 723 arranged at the bottom of the slide cylinder 722 and capable of moving up and down driven by the slide cylinder 722, a left straightening component 724 and a right straightening component 725 relatively arranged at the left and right ends of the second support plate 723 and used to straighten the lead.

[0066] Visual inspection camera 73 is mounted on first support plate 721. It photographs the incoming leads of the component before placing the butyl rubber pad to confirm whether the incoming leads have any abnormalities. After placing the butyl rubber pad, it photographs the leads of the component and the butyl rubber pad after placement to confirm that the butyl rubber pad has been properly placed and whether any abnormalities were present during placement. A light source panel 76, a reflective prism 77, and a light shielding plate 78 are also located below visual inspection camera 73. These light source panel 76, reflective prism 77, and light shielding plate 78 provide sufficient light for visual inspection camera 73, enabling clearer images.

[0067] A second avoidance opening 7231 is provided in the middle of the second support plate 723 for the second suction cup to move up and down, and a third suction cup for adsorbing the component is provided at the bottom. The third suction cup adsorbs the component to prevent the component from shaking, and enables the pick-and-place mechanism 71 to accurately place the butyl rubber pad on the lead.

The straightening plate 7243 is provided with a plurality of third avoidance grooves 7244 that conform to the shape of the lead wires and provide for their avoidance. The front ends of the third avoidance grooves 7244 are configured as V-shaped guide grooves 7245 to facilitate smooth entry of the lead wires into the third avoidance grooves 7244. There are two third avoidance grooves 7244, one for each of the two lead wires. The two straightening plates 7243 are opposite to each other left and right and staggered up and down. For example, the straightening plate 7243 of the left straightening component 724 is above and the straightening plate 7243 of the right straightening component 725 is below. It can also be set that the straightening plate 7243 of the left straightening component 724 is below and the straightening plate 7243 of the right straightening component 725 is above. There is no limitation here. The two straightening plates 7243 are extended simultaneously or successively and inserted between the two leads, so that the leads enter the third avoidance groove 7244 to straighten the leads. Regardless of whether the leads bend inward or outward, the two leads enter the corresponding first avoidance groove 7244 respectively, which can achieve straightening of the leads. Moreover, the left straightening component 724 and the right straightening component 725 are offset up and down, which can straighten the leads at different heights at the same time, and can straighten the leads in various bending states, completing the straightening of the leads more accurately and improving the quality of the lead straightening, so that the butyl rubber pad can be accurately placed on the leads.

[0069] When the photovoltaic heterojunction component butyl rubber gasket plugging device 100 provided by the present invention 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, completing the correction of the four sides of the component; at the same time, the transfer module 23 moves to the material taking station, the jacking 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 jacking 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 penultimate material tray. 26, the separation plate 241 supports the penultimate and 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 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 the material, the first motor 431 drives the first ball spline shaft module 433 to descend to the material tray 26 to pick up the material, 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. On the conveying platform 3, the butyl rubber pads are placed in the receiving grooves 37 of the three carriers 36 of the first carrier plate 31 or the second carrier plate 32 respectively, and the butyl rubber pads are sleeved on the contoured pins 38 to further position the butyl rubber pads. The first carrier plate 31 or the second carrier plate 32 moves to the right. At this time, the two carrier plates move in opposite directions to alternately transport materials. The XZ axis drive module 5 drives the mounting beam 6 to move along the XZ direction to move the three transport and placement units 7 to the upper right side of the transfer conveying platform 3. The three transport and placement units 7 move into place, and the third motor 711 drives the second lifting block 712 to drive the second ball spline shaft module 713 to descend, causing the second suction cup to descend to adsorb the butyl rubber pads. 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 to adsorb the butyl rubber pads. Block 712 drives the second ball spline shaft module 713 to rise and reset, and the XZ axis drive module 5 drives the mounting beam 6 to move along the XZ direction, so that the three handling and placement units 7 are respectively moved to the top of the three leads, and the visual inspection camera 73 takes pictures of the lead of the component before placing the butyl rubber pad to confirm whether there is any abnormality in the lead of the component. After confirming that there is no abnormality in the lead, the slide cylinder 722 drives the second support plate 723 to descend to the surface of the component, and the third suction cup absorbs the upper surface of the component. The straightening cylinder 7241 of the left straightening component 724 and the right straightening component 725 are driven simultaneously or successively, so that the two straightening plates 7243 are extended simultaneously or successively and inserted between the two leads, so that the lead enters the third avoidance groove 7244, so that the lead becomes vertical.The third motor 711 drives the second lifting block 712 to drive the second ball spline shaft module 713 to descend, causing the second suction cup to descend, so that 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 simultaneously, 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 the seal is formed and the lead wires are straightened and the butyl rubber pads are placed, the slide cylinder 722 drives the second support plate 723 to rise into position. The visual inspection camera 73 takes photos of the lead wires and butyl rubber pads after the butyl rubber pads are placed to confirm whether the butyl rubber pads have been placed properly. The blocking assembly 13, the first return assembly 14, and the second return assembly 15 are reset. The conveyor line 11 outputs the assembly, completing the placement of the assembly's butyl rubber pads. The next assembly is input into position via the conveyor line 11, and the next round of butyl rubber pad placement continues.
