Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell processing technology, and in particular to an automated equipment for edge wrapping of solar cells. Background Technology

[0002] There are currently four main edge-wrapping processes for photovoltaic cells: dispensing edge-wrapping, roller edge-wrapping, immersion edge-wrapping, and planar foam embedded edge-wrapping. Dispensing edge-wrapping technology originates from semiconductor technology and, while it meets the needs of conventional wafers, photovoltaic cells have four sides and four corners. This technology cannot guarantee the continuity of the edge-wrapping at the connection between the cell edge and the chamfer, easily leading to batch scrap. Immersion edge-wrapping mechanisms are difficult to meet the precision requirements of the photovoltaic industry. Roller edge-wrapping requires extremely high precision in roller processing and assembly, but the thinness and poor toughness of the solar cells make them highly susceptible to fragmentation during the edge-wrapping process.

[0003] While existing planar foam embedded edge banding can achieve both high precision and fragmentation prevention, a single workstation cannot complete the edge banding of the four sides and four corners of the battery cell. At least four edge banding workstations are required, which significantly increases the edge banding cost and causes waste on production lines with low production capacity. Utility Model Content

[0004] The present invention aims to provide an automated edge-wrapping device for battery cells to solve the problems of insufficient precision, easy generation of fragments, high edge-wrapping cost and low production efficiency in the existing edge-wrapping process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated edge-wrapping device for solar cells includes a straightening station, a material feeding and handling station, an edge-wrapping station, a material unloading and handling station, a UV curing station, and an unloading streamline station arranged sequentially.

[0007] The edge-binding station includes:

[0008] A rotary adsorption module includes an X-axis linear drive mechanism, a first mounting plate and a first rotary mechanism disposed on the X-axis linear drive mechanism, and an adsorption component mounted on the top of the first rotary mechanism, wherein the adsorption component is configured to fix the battery cell.

[0009] Two sets of slotted foam modules are symmetrically arranged on both sides of the rotating adsorption module. Each set of slotted foam modules includes: a Y-axis linear drive mechanism, a second mounting plate and a second rotating mechanism arranged on the Y-axis linear drive mechanism, a Z-axis lifting mechanism mounted on the top of the second rotating mechanism, a third mounting plate and an impregnated plate fixed on the Z-axis lifting mechanism, and foam arranged on the impregnated plate. The foam has at least four grooves.

[0010] The glue tank module is located below the foam.

[0011] As a further embodiment of this utility model: the edge-wrapping station also includes an alignment module, which includes an alignment camera disposed above the rotating adsorption module.

[0012] As a further embodiment of this utility model: the edge-wrapping station also includes a control module, which is configured to coordinate the movement of the X-axis linear drive mechanism, the Y-axis linear drive mechanism, the Z-axis lifting mechanism, the first rotation mechanism and the second rotation mechanism, so that the edge of the battery cell is inserted into different grooves of the foam in sequence.

[0013] As a further improvement of this utility model: both the first rotating mechanism and the second rotating mechanism are DD motor modules.

[0014] As a further improvement of this utility model, the movement direction of the X-axis linear drive mechanism is set perpendicular to the movement direction of the two sets of Y-axis linear drive mechanisms, forming a cross-shaped layout.

[0015] As a further improvement of this utility model, the X-axis linear drive mechanism, the Y-axis linear drive mechanism, and the Z-axis lifting mechanism are all screw transmission components.

[0016] As a further embodiment of this utility model, it also includes support plates disposed on both sides of the glue tank module and a scraper rod disposed between the two sets of support plates. The scraper rod is configured to contact the surface of the foam to scrape off excess glue when the foam rises from the glue tank module.

[0017] As a further embodiment of this utility model: the alignment station includes a conveyor for carrying battery cells, alignment plates disposed on both sides of the conveyor, and at least one alignment wheel disposed on the top of the alignment plate, wherein the alignment wheels on both sides are configured to perform position correction on the battery cells on the conveyor.

[0018] As a further embodiment of this utility model: the feeding and handling station includes a first conveyor, a conveyor plate disposed on the first conveyor, a cylinder fixed to the outer wall of the conveyor plate, and a suction-type mechanical claw connected to the bottom of the cylinder. The feeding and handling station and the discharging and handling station have the same structural configuration.

[0019] As a further improvement of this utility model: the UV curing station includes four sets of UV curing lamps arranged in a rectangular shape, and the irradiation angle of the UV curing lamps is adjustable.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Improve production efficiency: By adding a rotary adsorption module and two sets of slotted foam modules symmetrically arranged on both sides of the rotary adsorption module at the edge-wrapping station, and using a two-sided clamping method, the requirement of eight sides of the battery cell can be met by only four edge-wrapping operations at a single station. Compared with the ordinary foam embedded edge-wrapping process, this significantly improves production efficiency.

[0022] 2. Ensure edge binding accuracy: A second rotating mechanism is added to the slotted foam module to ensure that the edge binding angle of the solar cells can be finely adjusted when the opposite sides of the solar cells are not parallel, thus meeting the high requirements of the photovoltaic industry for edge binding accuracy.

[0023] 3. Reduce edge banding costs: The edge banding of the four sides and corners of the battery cells is completed at a single workstation, avoiding the significant increase in costs caused by edge banding at multiple workstations, and also preventing waste on low-capacity production lines.

[0024] 4. Prevents fragmentation: The flat foam embedded edge wrapping process effectively prevents the battery cells from fragmenting during the edge wrapping process. Attached Figure Description

[0051] The first conveyor 21 moves the suction-type mechanical claw 24 on the conveyor plate 22 to the top of the alignment station 1. The cylinder 23 drives the suction-type mechanical claw 24 to adsorb the battery cell. The aligned battery cell is picked up by the suction-type mechanical claw 24 and transported through the first conveyor 21 to the edge-wrapping station 3 for edge-wrapping work.

[0052] Edge banding station 3:

[0053] The edge-binding station 3 includes a rotary adsorption module 32, which includes an X-axis linear drive mechanism 321, a first mounting plate 322 and a first rotating mechanism 323 disposed on the X-axis linear drive mechanism 321, and an adsorption component 324 mounted on the top of the first rotating mechanism 323. The adsorption component 324 is configured to fix the battery cell.

[0054] Two sets of slotted foam modules 33 are symmetrically arranged on both sides of the rotating adsorption module 32. Each set of slotted foam modules 33 includes: a Y-axis linear drive mechanism 331, a second mounting plate 332 and a second rotating mechanism 333 arranged on the Y-axis linear drive mechanism 331, a Z-axis lifting mechanism 334 mounted on the top of the second rotating mechanism 333, a third mounting plate 335 and an impregnated plate 336 fixed on the Z-axis lifting mechanism 334, and foam 337 arranged on the impregnated plate 336. The foam 337 is provided with at least four grooves 338.

[0055] The glue channel module 34 is located below the foam 337;

[0056] Alignment module 31 includes an alignment camera disposed above the rotating adsorption module 32;

[0057] The control module is configured to coordinate the movements of the X-axis linear drive mechanism 321, the Y-axis linear drive mechanism 331, the Z-axis lifting mechanism 334, the first rotating mechanism 323, and the second rotating mechanism 333, so that the edges of the battery cells are sequentially inserted into different grooves 338 of the foam 337.

[0058] The first rotating mechanism 323 and the second rotating mechanism 333 are driven to adjust the angle based on the positioning data of the positioning camera 31; after the single-sided edge wrapping is completed, the first rotating mechanism 323 is driven to rotate 45°, and the Z-axis lifting mechanism 334 switches to the next groove 338 of the foam 337, and the edge wrapping of the four sides and chamfers of the battery cell is completed through four edge wrapping actions.

[0059] It also includes support plates 35 on both sides of the glue tank module 34 and a scraper 36 between the two sets of support plates 35.

[0060] The edge-sealing station 3 is the core part of this equipment, and its working principle is as follows:

[0061] Adsorption of battery cells: The X-axis linear drive mechanism 321 drives the first mounting plate 322 and the first rotating mechanism 323 on the first mounting plate 322 and the adsorption assembly 324 to move to the bottom of the suction mechanical claw 24 of the feeding and handling station 2, and places the battery cell on the top of the adsorption assembly 324 for adsorption. Then the X-axis linear drive mechanism 321 moves the adsorption assembly 324 and the battery cell to the edge wrapping station 3 for edge wrapping preparation.

[0062] Alignment adjustment: After the battery cell is positioned by the alignment camera 31 of the alignment module above, the control module drives the first rotation mechanism 323 to fine-tune the adsorption component 324 and the deflection angle of the battery cell according to the positioning data, so as to ensure that the battery cell is accurately inserted into the foam 337.

[0063] Preparation for edge binding: Before edge binding, foam 337 and glue-impregnated plate 336 are lowered into glue tank module 34 via Z-axis lifting mechanism 334. After being impregnated with edge binding glue, they are raised by lifting mechanism 334. After the surface of foam 337 is rubbed and glue-scraped by glue scraper 36, it reaches the edge binding waiting position.

[0064] Edge binding action: The slotted foam module 33 is equipped with an independent second rotating mechanism 333. When the opposite sides of the battery cell are not parallel, the angle of the foam 337 is finely adjusted to improve the edge binding accuracy. After the alignment camera 31 takes pictures and positions the battery cell, the first rotating mechanism 323 of the rotating adsorption module 32 finely adjusts the angle of the battery cell on the adsorption component 324 and controls the Y-axis linear drive mechanism 331 of the two sets of slotted foam modules 33 to run synchronously, moving the foam 337 on the two sets of second mounting plates 332 synchronously towards the battery cell. The two sides of the battery cell are respectively inserted into the grooves 338 on the surface of the two sets of foam 337 to complete the edge binding work.

[0065] After completing one edge wrapping, the foam 337 moves backward along the Y-axis linear drive mechanism 331. The first rotating mechanism 323 rotates 45°, causing the battery cell to rotate synchronously, preparing to wrap the two symmetrical chamfers of the battery cell. The Z-axis lifting mechanism 334 drives the third mounting plate 335 and the impregnated plate 336 to rise or fall, making the other grooves 338 on the foam 337 parallel to the battery cell. The above edge wrapping action is repeated until all four sides and chamfers of the battery cell are wrapped.

[0066] The foam 337 has at least four grooves 338, which correspond to the long side, short side, and four chamfers of the battery cell, totaling four sets of opposite sides. This allows the entire edge to be edged with just one application of edge-sealing adhesive, improving work efficiency.

[0067] Both the first rotating mechanism 323 and the second rotating mechanism 333 are DD motor modules, which have the characteristics of high torque and high precision, thus improving the alignment accuracy of the battery cells.

[0068] The X-axis linear drive mechanism 321 moves in a direction perpendicular to the movement directions of the two Y-axis linear drive mechanisms 331, forming a cross-shaped layout.

[0069] The X-axis linear drive mechanism 321, the Y-axis linear drive mechanism 331, and the Z-axis lifting mechanism 334 are all screw transmission components.

[0070] Material handling and unloading:

[0071] The structure of the unloading and handling station 4 is the same as that of the infeeding and handling station 2. After the edge banding is completed, the X-axis linear drive mechanism 321 moves the adsorption component 324 and the battery cell to the edge banding unloading area to wait for the suction-type mechanical claw 24 of the unloading and handling station 4 to grab them. After the adsorption component 324 has finished picking up the cells, it returns to the loading area to wait for the suction-type mechanical claw 24 of the infeeding and handling station 2 to place the battery cells. All the above actions are repeated.

[0072] UV curing:

[0073] UV curing station 5 includes four sets of UV curing lamps arranged in a rectangular shape, and the irradiation angle of the UV curing lamps is adjustable. The suction-type mechanical gripper 24 of the unloading and handling station 4 picks up the edge-wrapped battery cells and performs UV curing at the UV curing station 5. By adjusting the irradiation angle of the UV curing lamps, it is ensured that the adhesive at the edge of the battery cell can be fully cured, thus ensuring the quality of the edge wrapping.

[0074] Discharge flow line:

[0075] After curing, the solar cells are transported by the suction-type mechanical claw 24 at the discharge and handling station 4 to the conveyor belt at the discharge flow line station 6, and flow into the downstream machine, completing the entire automated process of edge wrapping the solar cells.

[0076] This utility model of automated cell edge-wrapping equipment achieves automation, high precision, high efficiency, and low cost in cell edge-wrapping through the rational setting of each workstation and the close cooperation between each mechanism. It meets the requirements of the photovoltaic industry for cell edge-wrapping technology and has broad prospects for promotion and application.

[0077] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
