Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell production technology, and in particular to a light-shielding tape feeding device and feeding line. Background Technology

[0002] In the field of photovoltaic module manufacturing technology, during the production of photovoltaic cells, it is necessary to first connect the continuously arranged cells into corresponding cell strings by welding ribbons. Before laser welding, light-shielding tape needs to be laid on the worktable to bond adjacent cells together. The black light-shielding tape can also reduce the influence of the current generated during the welding process.

[0003] In the existing technology, the traditional method of laying light-shielding tape usually requires the simultaneous arrangement of multiple rolls of tape capable of supporting all the battery cells, with the multiple rolls of light-shielding tape being coaxially arranged, and then pulled out simultaneously by a related traction mechanism. When this type of tape reel arrangement is used, the remaining radius of the light-shielding tape itself will affect the tape pulling process. Taking the pulled-out length L and the current remaining radius d of the roll as an example, the angular velocity of the tape reel axis rotation is approximately (360L) / (πd). However, in actual operation, it is difficult to meet the condition that the remaining radii of multiple tape reels are exactly the same. Therefore, in the actual tape pulling process, the angular velocity of multiple tape reels rotating coaxially will prioritize the tape reel with the larger remaining tape radius, resulting in overfeeding of tape reels with less remaining light-shielding tape. Furthermore, the pulling force on the light-shielding tape with the larger remaining radius will be too large, wasting tape and easily affecting subsequent processes. In addition, when using coaxially mounted tape reels, if there is a problem with the roll of tape on one of the reels, such as a lack of material or a damaged roll, all the corresponding rolls need to be unloaded and reassembled, which is a very cumbersome process and easily leads to waste of rolls.

[0004] Therefore, there is an urgent need to provide a light-shielding tape feeding device and feeding line to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a light-shielding tape feeding device that enables each roll of material to be supplied with the required light-shielding tape independently, ensuring that the feeding speed of the light-shielding tape is the same, improving the production quality of subsequent processes, and facilitating the replacement of rolls, thereby reducing maintenance costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This light-shielding tape feeding device is used for feeding rolls of light-shielding tape. The rolls are provided with mounting holes. The device includes a tray body and a loading mechanism. The tray body includes several rolls and several mounting discs corresponding to the number of rolls. The diameter of each mounting disc is not less than the diameter of the roll. Each mounting disc is equipped with a limit block for mounting the corresponding roll onto the corresponding mounting disc. The loading mechanism houses the tray body. Both ends of the bottom of the loading mechanism are provided with placement rollers. The distance between two placement rollers is not greater than the diameter of the mounting disc. The lower half of the mounting disc is rotatably limited between the two placement rollers. When the rolls rotate, they can drive the mounting discs to rotate.

[0008] Optionally, the aforementioned clamping roller includes clamping roller shafts fixed within the aforementioned material loading mechanism. Each of the two clamping roller shafts is provided with several sets of corresponding roller bearings, and each set of roller bearings abuts against the aforementioned mounting plate.

[0009] Optionally, the aforementioned clamping roller shaft is further provided with a plurality of limiting members, the limiting members and the aforementioned roller bearings are arranged at intervals on the aforementioned clamping roller shaft, and a gap is formed between two adjacent limiting members for the aforementioned mounting disc to pass through; two adjacent limiting members abut against the inner ring of the corresponding aforementioned roller bearing, so that the aforementioned roller bearings are fixed in relative position while ensuring rolling contact between the outer ring of the aforementioned roller bearings and the aforementioned mounting disc.

[0010] Optionally, the material feeding mechanism is further provided with a clamping roller drive, and the output end of the clamping roller drive is provided with a movable clamping roller. The movable clamping roller is used to limit the mounting plate near the top of the mounting plate to prevent the mounting plate from shaking during the feeding process.

[0011] Optionally, the main body of the material tray also includes several limiting plates, each limiting plate having a snap-fit ​​groove, into which a limiting block is inserted, and the snap-fit ​​groove and the limiting block are magnetically connected.

[0012] Optionally, a damping drive is fixed to the top of the material loading mechanism, and a damping assembly is provided at the output end of the damping drive. The damping assembly includes a plurality of damping elements that correspond one-to-one with the mounting plate. The damping elements can approach and abut against the mounting plate so that the damping elements apply a damping force to the mounting plate.

[0013] Beneficial effects:

[0014] The light-shielding tape feeding device of this invention consists of multiple material rolls and mounting discs stacked coaxially and alternately along the axial direction, forming a rotatable material tray body. The material tray body is supported by two placement clamping rollers in the material loading mechanism, and the mounting disc can drive the placement clamping rollers to rotate, ensuring the stability and smoothness of the material roll rotation during feeding. The mounting disc is fixedly equipped with a limiting block, and the mounting hole of the material roll is fitted into the limiting block. The limiting block fixed to the mounting disc only abuts against the adjacent mounting disc, so that the rotation speed of the material roll on each mounting disc can be kept different, thus ensuring that the light-shielding tape of the material roll is pulled out at the same speed when the tape is pulled out. Furthermore, when one material roll is used up or damaged, only the corresponding material roll and mounting disc need to be replaced, without affecting the disassembly and installation of other components. It is not necessary to replace the entire material tray body, reducing maintenance time and costs and improving maintenance efficiency.

[0015] Another object of the present invention is to provide a feeding line, which includes an incoming material cutting mechanism, a carrying mechanism, an adsorption and separation mechanism, a cell placement platform, and a light-shielding tape feeding device as described in any of the above embodiments; the incoming material cutting mechanism is used to cut the light-shielding tape provided by the light-shielding tape feeding device into light-shielding tape segments; the carrying mechanism is disposed below the incoming material cutting mechanism, and is used to carry the light-shielding tape segments and transport the light-shielding tape segments along the X direction to the loading position; the adsorption and separation mechanism is disposed above the loading position, and is used to adsorb both ends of the light-shielding tape segments and move the light-shielding tape segments to the cell placement platform.

[0016] Optionally, the aforementioned material cutting mechanism includes a pull-belt structure, a cutting structure, and a pressing structure. The pull-belt structure is disposed relative to the aforementioned light-shielding tape feeding device. The pull-belt structure is used to clamp the exposed ends of several of the aforementioned material rolls and pull the light-shielding tape out a predetermined length along the Y direction. The cutting structure is disposed between the pull-belt structure and the aforementioned light-shielding tape feeding device. The cutting structure can be relatively close to or away from the pull-belt structure and is used to cut several of the aforementioned light-shielding tapes into light-shielding tape segments. The pressing structure is disposed between the aforementioned light-shielding tape feeding device and the aforementioned cutting structure. The pressing structure is used to press and fix the exposed ends of the cut material rolls so that the material rolls can maintain an exposed end state after the aforementioned cutting mechanism moves.

[0017] Optionally, the aforementioned support mechanism includes a support plate, the lower end of which is connected to a lifting mechanism, a rotating mechanism, and a transverse mechanism. The top wall of the support plate is provided with a plurality of placement slots corresponding one-to-one with the aforementioned light-shielding tape. The lifting mechanism is used to drive the support plate to move along the Z direction, the rotating mechanism is used to rotate the support plate along the Z axis by a preset angle, and the transverse mechanism is used to drive the support plate to move along the X direction to the loading position.

[0018] Optionally, the bottom wall of the placement groove is provided with a plurality of adsorption holes spaced apart along the extension direction of the light-shielding tape segment. The adsorption holes are connected to a vacuum device and are used to adsorb and fix the light-shielding tape segment.

[0019] Beneficial effects:

[0020] The feeding line of this invention, through the aforementioned light-shielding tape feeding device, ensures that when multiple rolls of light-shielding tape are pulled out simultaneously, the feeding speed of the tape is uniform. This allows the incoming material cutting mechanism to simultaneously cut and provide multiple segments of light-shielding tape of equal length. After the carrying mechanism transports the segments to the loading position, the adsorption and separation mechanism adsorbs and transports the segments to the solar cell stack for subsequent application of the light-shielding tape to the solar cells. This feeding line provides segments of light-shielding tape of equal length at a consistent feeding speed, preventing over-feeding, reducing production costs, and improving production quality.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0041] The X direction described in this embodiment is as follows: Figure 7 As shown, the X direction is the width direction of the battery placement platform and the axial direction of the tray body 100; the Y direction is as follows: Figure 7 As shown in the diagram, the Y direction represents the length and movement direction of the battery placement platform; the Z direction (or Z-axis) is as follows: Figure 7 As shown, the Z direction (or Z-axis) is a vertical direction (or vertical axis) perpendicular to the horizontal plane.

[0042] Please refer to Figures 1 to 3 The light-shielding tape feeding device is used for feeding light-shielding tape rolls 110. The rolls 110 are provided with mounting holes 111. The device includes a tray body 100 and a loading mechanism 200. The tray body 100 includes a plurality of rolls 110 and a plurality of mounting trays 120 corresponding to the number of rolls 110. The diameter of each mounting tray 120 is not less than the diameter of the rolls 110. Each mounting tray 120 is equipped with a limiting block 130. The limiting block 130 is used for... The corresponding material roll 110 is installed on the corresponding mounting plate 120; the material loading mechanism 200 contains the material plate body 100, and the bottom ends of the material loading mechanism 200 are respectively provided with placement clamping rollers 210, the distance between the two placement clamping rollers 210 is not greater than the diameter of the mounting plate 120, and the lower half of the mounting plate 120 is rotatably limited between the two placement clamping rollers 210; wherein, when the material roll 110 rotates, it can drive the mounting plate 120 to rotate.

[0043] In this embodiment, the light-shielding tape feeding device consists of multiple coaxially and axially stacked rolls 110 and mounting discs 120, forming a rotatable disc body 100. The disc body 100 is supported by two placement rollers 210 within the loading mechanism 200, and the mounting disc 120 can drive the placement rollers 210 to rotate, ensuring stability and smooth feeding of the rolls 110. A limiting block 130 is fixedly mounted on the mounting disc 120, and the mounting holes 111 of the rolls 110 are fitted into the limiting block 130, thus connecting with the mounting disc 120. The fixed limiting block 130 only abuts against the adjacent mounting plate 120, so that the rotation speed of the material roll 110 on each mounting plate 120 can be kept different, so that the light-shielding tape of the material roll 110 is pulled out at the same speed when the tape is pulled; and when one of the material rolls 110 is used up or damaged, only the corresponding material roll 110 and mounting plate 120 need to be replaced, without affecting the disassembly and installation of other components, without having to replace the entire material plate body 100, thus reducing maintenance time and maintenance costs and improving maintenance efficiency.

[0044] In this embodiment, the material loading mechanism 200 is an L-shaped placement box with an opening for picking up and placing the material tray body 100. Specifically, the mounting tray 120 is an aluminum alloy tray. The material roll 110 and the mounting tray 120 are coaxial and stacked alternately along the axial direction. It is lightweight and has good mechanical properties, which can reduce manufacturing costs and improve service life.

[0045] like Figure 3 As shown, the limiting block 130 in this embodiment is also provided with a limiting bearing 131 inside. The limiting bearing 131 can be used to insert rollers inside, so that multiple mounting discs 120 and multiple material rolls 110 are kept on the same axis, while not affecting the independent rotation between each mounting disc 120 and each material roll 110.

[0046] like Figure 1 and Figure 4 As shown, the aforementioned material loading mechanism 200 is further fixedly equipped with a clamping roller drive 310. The output end of the clamping roller drive 310 is provided with a movable clamping roller 330. The movable clamping roller 330 is used to limit the mounting plate 120 near its top end, preventing the mounting plate 120 from shaking during the feeding process. The clamping roller drive 310 is specifically a cylinder. Two placement clamping rollers 210 and one movable clamping roller 330 form a triangle, abutting against the mounting plate 120 from three directions to clamp the mounting plate 120, ensuring the stability of the mounting plate 120 during rotation and preventing the mounting plate 120 from jumping due to unstable tension when the belt is pulled.

[0047] Furthermore, the output end of the clamping roller drive 310 is connected to a clamping roller connecting rod 320, and the clamping roller connecting rod 320 is connected to a movable clamping roller 330, so that the clamping roller connecting rod 320 drives the movable clamping roller 330 to move up and down and abut against the top of the mounting plate 120, thereby limiting and fixing the mounting plate 120.

[0048] Please refer to Figure 4 and Figure 5 In this embodiment, the movable clamping roller 330 and the placement clamping roller 210 have the same structure. Further, the placement clamping roller 210 includes a clamping roller shaft 211 fixed within the material loading mechanism 200. Each of the two clamping roller shafts 211 is provided with several sets of corresponding roller bearings 212, each set of roller bearings 212 abutting against the mounting plate 120. The clamping roller shaft 211 is fixed within the material loading mechanism 200 and will not be driven to rotate by the mounting plate 120. The roller bearings 212 abut against the mounting plate 120, supporting and clamping the mounting plate 120, and can also be driven to rotate by the mounting plate 120, ensuring the stability and smooth rotation of the mounting plate 120.

[0049] In a preferred embodiment, the clamping roller shaft 211 is further provided with a plurality of limiting members 213. The limiting members 213 and the roller bearings 212 are arranged at intervals on the clamping roller shaft 211, with a gap formed between adjacent limiting members 213 for the mounting plate 120 to pass through. Adjacent limiting members 213 abut against the inner ring of the corresponding roller bearing 212 to ensure that the outer ring of the roller bearing 212 maintains rolling contact with the mounting plate 120 while fixing its relative position. The limiting members 213 clamp and fix the roller bearings 212, ensuring that the position of the roller bearings 212 does not shift. In this embodiment, the diameter of the limiting members 213 is larger than the diameter of the roller bearings 212, and it can also clamp the mounting plate 120 from both sides, preventing the mounting plate 120 from becoming eccentric or shifting.

[0050] Furthermore, considering that the mounting plate 120 is thinner than the roller bearing 212, it is preferable to set the center section of the limiting ring to be I-shaped, with the empty part in the middle used to install the roller bearing 212, and the edge parts on both sides used to limit the mounting plate 120.

[0051] like Figure 1 and Figure 5As shown, optionally, a damping drive member 410 is fixedly provided on the top of the material loading mechanism 200. A damping assembly is provided at the output end of the damping drive member 410. The damping assembly includes several damping members 420 corresponding one-to-one with the mounting plate 120. The damping members 420 can approach and abut against the mounting plate 120 to apply a damping force to the mounting plate 120. In this embodiment, the damping drive member 410 is a cylinder that applies force to the damping assembly through a linkage mechanism, causing the damping members 420 to apply a damping force to the mounting plate 120. The surface material of the damping members 420 is rubber, which provides greater friction and will not damage the mounting plate 120. The damping members 420 provide damping to the mounting plate 120, preventing excessive rotation of the mounting plate 120 due to inertia when the material roll 110 is pulled too fast, preventing the material roll 110 from releasing excess light-blocking tape, and ensuring the stability of the material supply.

[0052] Please continue to refer to this. Figure 3 and Figure 6 Optionally, the main body 100 of the material tray further includes several limiting discs 140. Each limiting disc 140 is provided with a snap-fit ​​groove 141, and a limiting block 130 is inserted into the snap-fit ​​groove 141. The snap-fit ​​groove 141 and the limiting block 130 are magnetically connected. In this embodiment, an iron ring 132 is provided on the end face of the limiting block 130 away from the mounting disc 120. A magnet is provided in the snap-fit ​​groove 141. The magnet and the iron ring 132 attract each other, so that the limiting disc 140 is fixed on the limiting block 130, thereby clamping the material roll 110 between the limiting disc 140 and the mounting disc 120, and fixing the material roll 110. The magnetic attraction method facilitates disassembly and assembly. In order to facilitate the installation and limiting of the magnet, a placement groove 651 for placing the magnet is also provided in the snap-fit ​​groove 141.

[0053] like Figure 6 As shown, the limiting block 130 is located at the center of the mounting plate 120. The limiting block 130 has three protrusions that are evenly spaced axially. Each protrusion is provided with a guide groove. A card 133 is inserted into the guide groove so that the mounting hole 111 at the center of the material roll 110 is fastened to the protrusion of the limiting block 130 by the card 133, thereby fixing the material roll 110 on the side of the mounting plate 120.

[0054] Please refer to Figures 7 to 9Another object of the present invention is to provide a feeding line, which includes an incoming material cutting mechanism, a carrying mechanism, an adsorption and separation mechanism 700, a battery cell placement platform 800, and a light-shielding tape feeding device as described in any of the above embodiments; the incoming material cutting mechanism is used to cut the light-shielding tape provided by the light-shielding tape feeding device into light-shielding tape segments; the carrying mechanism is disposed below the incoming material cutting mechanism, and is used to carry the light-shielding tape segments and transport the light-shielding tape segments along the X direction to the loading position; the adsorption and separation mechanism 700 is disposed above the loading position, and is used to adsorb both ends of the light-shielding tape segments and move the light-shielding tape segments to the battery cell placement platform 800.

[0055] This feeding line, through the aforementioned light-shielding tape feeding device, ensures that when multiple rolls 110 of light-shielding tape are pulled out simultaneously, the feeding speed of the tape is uniform. This allows the incoming material cutting mechanism to simultaneously cut and provide multiple segments of the same length of light-shielding tape. After the carrying mechanism transports the tape segments to the loading position, the adsorption and separation mechanism 700 adsorbs and transports the tape segments to the solar cell stack for subsequent application of light-shielding tape to the solar cells. This feeding line provides tape segments of the same length at a consistent feeding speed, preventing overfeeding, reducing production costs, and improving production quality.

[0056] A feeding roller 511 is also provided between the light-shielding tape feeding device and the incoming material cutting mechanism to provide support for the light-shielding tape during the intermediate transition and prevent the light-shielding tape from bending when it is too long. An incoming material sensor 512 is also provided above the feeding roller 511 to detect the feeding speed and feeding status of the corresponding light-shielding tape. It can be a fiber optic sensor or a photoelectric sensor, which will not be described in detail here.

[0057] like Figure 8 As shown, the material cutting mechanism includes a pull-belt structure 620, a cutting structure 630, and a pressing structure 640. The pull-belt structure 620 is disposed opposite to the light-shielding tape feeding device. The pull-belt structure 620 is used to clamp the exposed ends of several material rolls 110 and pull the light-shielding tape out a predetermined length along the Y direction. The cutting structure 630 is disposed between the pull-belt structure 620 and the light-shielding tape feeding device. The cutting structure 630 can be relatively close to or away from the pull-belt structure 620 and is used to cut several light-shielding tapes into light-shielding tape segments. The pressing structure 640 is disposed between the light-shielding tape feeding device and the cutting structure 630. The pressing structure 640 is used to press and fix the exposed ends of the cut material rolls 110 so that the material rolls 110 can maintain an exposed end state after the cutting structure 630 moves.

[0058] Specifically, the cutting structure 630 synchronously cuts the multiple light-shielding tapes after the pull-belt structure 620 pulls them out, forming light-shielding tape segments of the required preset length. The cutting structure 630 consists of a cutting blade and a cutting blade power actuator, which will not be described in detail here. The cutting mechanism is slidably connected to the cutting bracket 610, and after cutting, the cutting mechanism can move back towards the holding structure 640, so that the exposed end of the material roll 110 pressed by the holding structure 640 is exposed, making it easier for the pull-belt structure 620 to approach the holding structure 640 and clamp the exposed end of the material roll 110, so that the cutting structure 630 does not block the pull-belt structure 620. The holding structure 640 is used to hold the light-shielding tape during cutting and to ensure that the end of the light-shielding tape does not retract itself when the cutting structure 630 moves back. The above structure makes it easy for the pull-belt mechanism to pull the end of the light-shielding tape again, which will not be described in detail here.

[0059] In this embodiment, the pull strap structure 620, the cutting structure 630, and the pressing structure 640 are all disposed on the cutting bracket 610, and the cutting structure 630 is slidably disposed on the cutting bracket 610.

[0060] Optionally, the aforementioned belt-pulling structure 620 includes a belt-pulling cylinder 621 and a plurality of grippers 622 for correspondingly clamping the exposed ends of the material roll 110. The belt-pulling cylinder 621 is fixed to the cutting bracket 610, and the grippers 622 are disposed at the output end of the belt-pulling cylinder 621. Under the action of the belt-pulling cylinder 621, the belt-pulling structure 620 can move forward or backward relative to the material roll, thereby allowing the grippers 622 to pull out the material roll 110 after gripping its exposed ends.

[0061] The cell placement platform 800 is used to place 12 or other numbers of cells. It is equipped with a preheating device to heat the light-shielding tape section to increase the adhesion of the light-shielding tape section so that it can be more easily and firmly bonded to the edge of the cell.

[0062] like Figure 9As shown, the above-mentioned supporting mechanism includes a supporting plate 650. The lower end of the supporting plate 650 is connected to a lifting mechanism 661, a rotating mechanism 662, and a transverse mechanism 663. The top wall of the supporting plate 650 is provided with a plurality of placement slots 651 corresponding one-to-one with the above-mentioned light-shielding tape. The lifting mechanism 661 is used to drive the supporting plate 650 to move along the Z direction. The rotating mechanism 662 is used to rotate the supporting plate 650 along the Z axis by a preset angle. The transverse mechanism 663 is used to drive the supporting plate 650 to move along the X direction to the loading position. Specifically, the carrier plate 650 reciprocates between the tape pulling station and the loading position via the transverse mechanism 663. During tape pulling, the carrier plate 650 moves to the bottom of the tape pulling station and aligns with each light-shielding tape. Then, the lifting mechanism 661 lifts the carrier plate 650 to fix the light-shielding tape in the placement groove 651 of the carrier plate 650. After the carrier plate 650 has fixed the light-shielding tape, the cutting mechanism cuts the light-shielding tape. Then, the transverse mechanism 663 moves the carrier plate 650 to the loading position. The rotating mechanism 662 rotates the carrier plate 650 90° around the Z-axis so that the light-shielding tape segment is placed horizontally. Finally, the adsorption and separation mechanism 700 adsorbs and transports the light-shielding tape segment on the carrier plate 650 for subsequent application processes.

[0063] Optionally, the bottom wall of the placement groove 651 is provided with a plurality of adsorption holes 652 spaced apart along the extension direction of the light-shielding tape segment. The adsorption holes 652 are connected to a vacuum device and are used to adsorb and fix the light-shielding tape segment. After the support plate 650 is lifted upward, the adsorption holes 652 in each placement groove 651 come into contact with the surface of the light-shielding tape. Then, the vacuum device introduces negative pressure into the adsorption holes 652 so that the light-shielding tape is adsorbed on the support plate 650. During cutting, the light-shielding tape is firmly adsorbed, ensuring the quality of the light-shielding tape segment during cutting, thereby improving the subsequent processing quality.

[0064] Optionally, the adsorption separation mechanism 700 includes an adsorption transfer guide rail 710, an adsorption support 720, and a suction head 730. The adsorption transfer guide rail 710 extends along the Y direction, and the adsorption support 720 is slidably connected to the adsorption transfer guide rail 710. Suction heads 730 are provided at both ends of the adsorption support 720 along the X direction, so that the suction heads 730 adsorb and transfer the light-shielding tape segment from both ends, ensuring the straight transport of the light-shielding tape segment.

[0065] The adsorption and spacing mechanism 700 also includes a spacing mechanism for equally spaced adsorption brackets 720. Here, an existing equally spaced variable spacing module can be used. When adsorbing the light-shielding tape, multiple adsorption brackets 720 are close to each other. After separating them (the spacing is the length of one solar cell), the light-shielding tape segment is placed on the solar cell placement platform 800 with the adhesive side facing up. Then, the solar cells are placed according to the position of the light-shielding tape segment. This will not be described in detail here.
