Description

TECHNICAL FIELD

[0001] The utility model relates to solar cell string production technical field, concretely relates to a cell piece tape sticking mechanism. BACKGROUND

[0002] In some BC (Back Contact) cell strings, the back of the cell piece will be attached with a tape, from the front of the cell string, the tape covers the solder strip at the gap between the two adjacent cell pieces, the color of the tape is similar to that of the cell piece, which can improve the appearance of the cell string.

[0003] In the prior art, when making a BC cell string, a plurality of cell pieces arranged at equal intervals and a plurality of solder strips are prepared, and a tape is attached to the gap between the two adjacent cell pieces, then the plurality of cell pieces and the plurality of solder strips are combined and heated to form a cell string.

[0004] Due to the influence of the existing string making process, there are two ways to attach the tape to the cell piece: one is that the back of the cell piece is upward, a plurality of cell pieces are arranged at equal intervals, the tape has adhesion, and the same tape is attached to the adjacent long edge of the two adjacent cell pieces; the second is that a plurality of tapes are arranged at equal intervals on a heating platform, the back of the cell piece is downward so that the adjacent long edges of the two adjacent cell pieces are stacked on the same tape, and the upper surface of the tape has a layer of hot melt adhesive film, and the tape is heated to be adhered to the cell piece.

[0005] In a new BC cell string making process, the cell piece and the solder strip are alternately combined on a conveying mechanism, and a continuous cell string is made after passing through a heating mechanism, wherein the tape is attached to one long edge of each cell piece on the cell piece feeding transmission line. In the new string making process, if the tape is attached to one long edge of the cell piece by using the above first method, since the part of the tape extending out of the cell piece still has adhesion, and the cell piece is very thin, the tape rolling in the subsequent transmission process may contact and adhere to the conveying belt; if the tape is attached to one long edge of the cell piece by using the above second method, a carrying mechanism and a heating platform need to be added, the carrying mechanism is used to carry the cell piece between the heating platform and other mechanisms, which increases the complexity and cost of the string making equipment.

DETAILED DESCRIPTION

[0027] The technical scheme and technical effects of the utility model are further described in detail below in combination with the drawings of the utility model.

[0028] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated;It can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In the description of the embodiment, the terms "upper", "lower", "right", and other orientation or position relationship are based on the orientation or position relationship shown in the drawings, which is only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must be provided with a specific orientation, constructed and operated in a specific orientation, so it cannot be understood as a limitation on the utility model. It should be noted that in this paper, relationship terms such as "first" and "second" are only used to distinguish the first feature from the second feature, and do not necessarily require or imply any such actual relationship or order between the features.

[0030] The utility model provides a kind of battery piece adhesive tape mechanism, adhesive tape 500 is pasted on the state of battery piece 400 as shown in Figure 1 The back of battery piece 400 is upward, and adhesive tape 500 is pasted on one long edge of battery piece 400. Figure 1In the example, two pieces of tape 500 are attached to different long edges of two battery cells 400. The two pieces of tape 500 have different lengths, and the two battery cells 400 are adjacent to each other in the battery string. The tape 500 is non-sticky at room temperature. The tape 500 comprises at least two layers, one of which is in contact with the battery cells 400 and is a hot-melt adhesive film. The hot-melt adhesive film becomes sticky when heated to a certain temperature. In actual production, the same tape 500 specifications can be used throughout the battery string, meaning all pieces of tape 500 can be the same length.

[0031] like Figures 2-3 As shown, the battery cell tape laminating mechanism includes a tape making unit 100, a tape splicing unit 200, and a tape transport unit 300. The tape making unit 100 includes a tape pulling hand 110 and a cutter assembly 120. The tape pulling hand 110 can reciprocate along a first horizontal direction. The cutter assembly 120 is used to cut the tape 500. The tape splicing unit 200 includes a tape splicing platform 210, which is arranged to be raised and lowered below the movement path of the tape pulling hand 110. The tape transport unit 300 includes a drive assembly 310 and a tape suction gripper 320. The drive assembly 310 is drivably connected to the tape suction gripper 320, and the tape suction gripper 320 has a built-in heating rod. The drive assembly 310 can drive the tape suction gripper 320 to move up and down and horizontally.

[0032] During operation, first, the tape splicing platform 210 moves down to avoid the tape pulling hand 110, and the tape pulling hand 110 approaches the cutter assembly 120, clamps the end of the tape 500 and pulls it out, and the pulled-out part of the tape 500 is located above the tape splicing platform 210; then, the tape splicing platform 210 moves up, the cutter assembly 120 acts to cut the tape 500, and the tape pulling hand 110 releases the end of the tape 500, so that the tape 500 is laid on the tape splicing platform 210; finally, the driving assembly 310 drives the tape suction The gripper 320 moves. After the suction gripper 320 absorbs the tape 500 on the tape splicing platform 210, it continues to move. Simultaneously, the heating rod operates, causing the tape 500 to become sticky. After the tape 500 contacts the battery cell 400, it adheres to the battery cell 400. The suction gripper 320 releases the tape 500 and separates from it. After the tape 500 cools, a portion of the bottom surface of the tape 500 adheres to the battery cell 400, while the other portion loses its stickiness.

The first suction hole 3122 is connected with the air suction device through a gas passage in the suction plate 312, so that it generates suction force to adsorb the adhesive tape 500. The width of the adhesive tape 500 is about 5mm, in order to accommodate the heating rod, the width of the suction plate 312 is usually much larger than 5mm, since the adhesive tape 500 is very thin, the excessive width of the bottom surface of the suction plate 312 means that the bottom surface of the suction plate 312 and the surface of the tape receiving platform 210 need to have high flatness, a boss 3121 can be arranged at the bottom of the suction plate 312, and the first suction hole 3122 is located on the boss 3121, the boss 3121 with a smaller width is in contact with the adhesive tape 500, so that the machining precision requirement of the suction plate 312 and the tape receiving platform 210 can be reduced.
