[0031] As Figures 1 to 10 shown, the photovoltaic curing device provided by the utility model comprises a conveying unit 100, a feeding unit 200, a curing unit 300 and a rack 400. The rack 400 is used to support the conveying unit 100, the feeding unit 200 and the curing unit 300, the conveying unit 100 is used to convey the cell sheet and pass through the curing unit 300, the feeding unit 200 is used to transfer the cell sheet to be cured to the conveying unit 100, and the curing unit 300 is used to carry out curing treatment on the cell sheet.

[0032] The conveying unit 100 comprises two conveying chains 101 arranged in parallel and a support unit arranged on the conveying chains 101 and used to carry the cell sheet. The cell sheet to be cured is transferred to the support unit through the feeding unit 200, the support unit and the cell sheet thereon are driven to move through the conveying chains 101, and pass through the area where the curing unit 300 is located, so that the curing unit 300 carries out curing treatment on the cell sheet.

[0033] The two conveying chains 101 are arranged in parallel and spaced apart, and the extension direction of the conveying chains 101 is the conveying direction of the conveying unit 100. The two ends of the conveying chains 101 in the extension direction are respectively a feeding position and a discharging position, the feeding unit 200 is arranged close to the feeding position, and the curing unit 300 is located between the feeding position and the discharging position.

[0034] The support unit comprises support members 102 connected to the two conveying chains 101 respectively, and the cell sheet is carried by the support members 102 on the two conveying chains 101. It can be understood that the cell sheet is located between the two conveying chains 101, at least two support members 102 jointly carry a cell sheet, and the two support members 102 are located on different conveying chains 101 respectively, that is, the two conveying chains 101 jointly carry and convey the cell sheet, so as to ensure the stability of the cell sheet in the conveying process.

[0035] In a specific embodiment, the support members 102 on the two conveying chains 101 extend towards each other, that is, the extension direction of the support members 101 is perpendicular to the extension direction of the conveying chains 101.

[0036] The conveying chains 101 are provided with a plurality of support members 102 arranged at intervals, and a plurality of cell sheets can be conveyed at the same time through the plurality of support members 102. The spacing between two adjacent support members 102 on the same conveying chain 101 can be determined according to the size of the cell sheet or the spacing required to be maintained between the cell sheets.

[0037] In one embodiment, the supports 102 on the two conveying chains 101 are arranged staggered, i.e. the supports 102 on the two conveying chains 101 are not in alignment. In this embodiment, a cell can be carried by only two supports 102.

[0038] Specifically, two supports 102 form a support unit, and the two supports 102 in the same support unit are located on different conveying chains 101, and the interval of the two supports 102 along the conveying direction of the conveying unit 100 is less than the length of a cell along the conveying direction of the conveying unit 100. In this way, the two supports 102 can realize the carrying and conveying of a cell. The interval of two adjacent supports 102 on the same conveying chain 101 is determined according to the interval required to be maintained between cells.

[0039] Of course, in this embodiment, more supports 102, such as three or four supports 102, can be used to support a cell to improve the stability of the cell during conveying.

[0040] In another embodiment, the supports 102 on the two conveying chains 101 are in alignment, i.e. the supports 102 are symmetrically arranged on the two conveying chains 101 along the central axis of the conveying unit 100. In this embodiment, four supports 102 are required to carry a cell.

[0041] Specifically, four supports 102 form a support unit, and two supports 102 are arranged on each conveying chain 101. The interval of the two supports 102 in the same support unit on the same conveying chain 101 along the conveying direction of the conveying unit 100 is less than the length of a cell along the conveying direction of the conveying unit 100. In this way, the four supports 102 can realize the stable conveying of a cell. The interval of two adjacent supports 102 on the same conveying chain 101 which are not in the same support unit is determined according to the interval required to be maintained between cells.

[0042] Preferably, there is a gap between the two supports 102 in alignment. In this way, the supports 102 can reduce the shielding of the cell, so that the curing unit 300 can perform curing treatment on the cell.

[0043] The support 102 comprises a support rod 102a connected to the transmission chain 101, and a rubber cap 102b located at one end of the support rod 102a away from the transmission chain 101. The rubber cap 102b is used to carry the battery piece, and the rubber cap 102b can avoid damage to the battery piece during the transfer and transmission of the battery piece.

[0044] The transmission unit 100 further comprises a first limiting plate 103 located above the support 102, a plurality of first limiting members 103a arranged along the extension direction of the transmission chain 101 are rotatably installed on the first limiting plate 103, and the support 102 is in contact with the first limiting members 103a.

The first limiting members 103a are in contact with the top of the support rod 102a. During the transmission of the support 102 and the battery piece thereon along with the transmission chain 101, the first limiting members 103a can effectively limit the upward bending of the support rod 102a, thereby preventing the battery piece from shaking, thereby improving the stability of the battery piece during the transmission process.

[0046] In this embodiment, the first limiting members 103a are balls. Through the rolling contact between the balls and the support rod 102a, the resistance of the first limiting members 103a to the support rod 102a can be reduced.

[0047] The transmission unit 100 further comprises a second limiting plate 104 located below the support 102, a plurality of second limiting members 104a arranged along the extension direction of the transmission chain 101 are rotatably installed on the second limiting plate 104, and the support 102 is in contact with the second limiting members 104a.

[0048] Specifically, the second limiting plate 104 is fixed to the rack 400 by a support frame (not shown in the figure), and the extension direction of the second limiting plate 104 is the same as the extension direction of the transmission chain 101. The second limiting members 104a are in contact with the bottom of the support rod 102a. During the transmission of the support 102 and the battery piece thereon along with the transmission chain 101, the second limiting members 104a can effectively limit the downward bending of the support rod 102a, thereby preventing the battery piece from shaking, thereby improving the stability of the battery piece during the transmission process.

[0049] In this embodiment, the second limiting member 104a adopts a guide bearing. Through the rolling contact between the guide bearing and the support rod 102a, the resistance of the second limiting member 104a to the support rod 102a can be reduced. Of course, the first limiting member 103a and the second limiting member 104a can be interchanged or adopt the same structure.

[0050] It can be understood that, during the transmission of the support member 102 and the battery piece thereon along with the transmission chain 101, the support rod 102a is in contact with the first limiting member 103a and the second limiting member 104a at the same time, so as to completely limit the up-and-down swing of the support member 102 during the transmission, thereby improving the stability during the transmission of the battery piece.

[0051] It needs to be particularly pointed out that, during the transmission of the support member 102 along with the transmission chain 101, the moving direction of part of the support member 102 is from the feeding position to the discharging position, and this part of the support member 102 carries the battery piece; the moving direction of another part of the support member 102 is from the discharging position to the feeding position, and this part of the support member 102 does not carry the battery piece; the support member 102 carrying the battery piece is located above the support member 102 not carrying the battery piece.
