Description

Technical Field

[0001] This application relates to the field of solar photovoltaic cell production, specifically a handling mechanism and a cell stringing device. Background Technology

[0002] A battery string consists of battery cells and solder strips, with the solder strips used to connect two adjacent battery cells.

[0003] During battery string production, a pressure tool is used to press the solder ribbon onto the battery cells to prevent it from shifting. The solder ribbon is held and pulled onto the cells by a traction mechanism. Because the clamps holding the solder ribbon require space, traditional pressure tools can only press onto the unclamped portion of the ribbon. When the clamps release the ribbon, the end may curl up, and this curled end cannot be secured to the battery cells, making it difficult to guarantee the quality of the battery string. Summary of the Invention

[0089] By providing a second picking unit 80 on the conveying mechanism 2, the adhesive film 105 can be picked up at the same time as the pressing fixture 1, so that the conveying mechanism 2 can be used for battery stringing equipment that produces battery strings with adhesive film, thus expanding the application range of the conveying mechanism 2.

[0090] In one embodiment, the conveying mechanism 2 may optionally include a third pickup unit 90, which is disposed on one side of the base 50 and configured to pick up and release the battery cell. Optionally, the third pickup unit 90 includes a second suction cup 91.

[0091] By providing a third pickup unit 90 on the conveying mechanism 2, the battery cells can be picked up by the second suction cup 91 while the pressure plate 1 is being picked up, thus expanding the applicability of the conveying mechanism 2.

[0092] When the conveying mechanism 2 in this application includes a second picking unit 80, that is, when it can pick up the film 105 while picking up the presser 1, the presser 1 can have a variety of implementations.

[0096] The first pressing part 20 of the presser 1 adopts a pressing strip 21 with a through hole 211, which allows the second picking part 80 of the conveying mechanism 2 to pass smoothly through the through hole 211.

[0097] The second embodiment of the presser 1 is similar to the first embodiment, except that the press strips 21 are arranged in a certain way.

[0101] The first pressing part 20 of the presser 1 uses spaced pressing strips 21, which allows the second picking part 80 of the conveying mechanism 2 to pass smoothly through the gap between the two pressing strips 21.

[0102] like Figures 12-13 As shown, optionally, a third embodiment of the presser 1 further includes a frame 10, a first pressing part 20 is installed below the frame 10, the first pressing part 20 is provided with a first end face for pressing the adhesive film body, and a second pressing part 30 is rotatably installed on the frame 10, the second pressing part 30 is provided with a second end face for pressing the adhesive film and the end of the welding strip.

[0103] The first pressing part 20 includes at least two spaced pressing strips 21, and each pressing strip 21 has multiple protrusions extending vertically on both sides in the length direction;

[0104] At this time, the second pickup part 80 of the conveying mechanism 2 used in conjunction with the third embodiment of the pressure fixture 1 includes two sets of first suction cups 81. Each set of first suction cups 81 is arranged along the width direction of the pressure strip 21. The two sets of first suction cups 81 are located on the outer sides of both ends of each pressure strip 21 in the length direction. Each first suction cup 81 is located in the gap formed by the four protrusions at the ends of the corresponding two pressure strips 21. The two sets of first suction cups 81 are configured to pass through the first pressing part 20 and suck up the adhesive film to be picked up.

[0105] The first pressing part 20 of the presser 1 adopts a pressing strip 21 with protrusions, which allows the second picking part 80 of the conveying mechanism 2 to pass smoothly through the gap formed by the protrusions.

[0106] In the three embodiments of the pressure fixture 1 described above, the second clamping part 30 can adopt the same structure. Optionally, as shown... Figures 10-11 As shown, the second pressing part 30 includes a pressure plate 31 and a rotating mechanism 32. The rotating mechanism 32 is rotatably mounted on the frame 10, and the pressure plate 31 is mounted on the rotating mechanism 32. The bottom surface of the pressure plate 31 is the second end face of the second pressing part 30.

[0107] The rotating mechanism 32 includes a mounting base 321, a pressing member 322, and a second spring 323;

[0108] Mounting base 321 is mounted on frame 10, pressing member 322 is rotatably mounted on frame 10, pressing member 322 is located below mounting base 321, pressure plate 31 is connected to one side of pressing member 322, and second spring 323 is installed between pressure plate 31 and mounting base 321.

[0109] When the pressing member 322 is pressed down, the bottom surface of the pressure plate 31 is tilted upward; after the pressing member 322 is released, the second spring 323 makes the bottom surface of the pressure plate 31 either horizontal or tilted downward.

[0110] The pressure plate 31 is flipped by pressing the pressing part 322, and the pressure plate 31 is reset by the second spring 323. The structure is simple and the operation is flexible.

[0111] like Figures 14-16 As one embodiment, the working process of the press 1 and the conveying mechanism 2 in this application for producing battery strings with adhesive film is as follows: Before placing the press 1 and the front adhesive film 105, the traction gripper 200 has already clamped the welding strip 103. The conveying mechanism 2 moves the press 1 and the front adhesive film 105 onto the welding strip 103. At this time, the pressure bar 21 of the first pressing part 20, which is in a lower position, first presses the adhesive film 105 onto the battery cell 104. The pressure plate 31 of the second pressing part 30 is located in the clamp of the traction gripper 200. Above the holding end, the edge of the front adhesive film 105 rests on the supporting surface 201 of the traction gripper 200; then the transport mechanism 2 releases the pressure 1, and the pressing member 322 of the rotating mechanism 32 loses the pressing of the transport mechanism 2, and the pressure plate 31 rotates downward, pressing the edge of the front adhesive film 105 against the supporting surface 201 of the traction gripper 200. After the traction gripper 200 releases the welding strip 103 and removes it horizontally, the pressure plate 31 presses the ends of the adhesive film 105 and the welding strip 103 onto the battery cell 104.

[0119] After the grippers of the ribbon laying mechanism are removed, the second pressing part 30 of the presser 1 rotates back to reset so as to press the end of the adhesive film 105 and the end of the ribbon 103 onto the battery cell 104.

[0120] The conveying mechanism is also configured to convey the stacked solar cells 104, adhesive film 105, welding ribbon 103 and press 1 to the fixing mechanism, which is configured to fix the solar cells 104, adhesive film 105 and welding ribbon 103 together.
