Description

Technical Field

[0001] This application relates to the field of solar grid cell processing technology, specifically to an automatic compensation position mechanism for a welding strip positioning fixture for grid cells. Background Technology

[0002] Most existing non-destructive dicing machines diced the cells from the front, inspected them, and then fed them into the next process. The cells were then heated and conveyed to a designated position on the stringing machine with the front side facing up for front-side stringing.

[0003] However, due to the defects in the above-mentioned production process, there is a risk of damage such as incomplete welding, over-welding, and exposed white areas when welding the welding strip and the battery cell. In order to achieve better automated production and realize integrated welding, thereby reducing the risk of damage such as incomplete welding, over-welding, and exposed white areas when welding the welding strip and the battery cell, a mechanism for automatic compensation of the fixture position is needed. Summary of the Invention

[0004] The purpose of this application is to provide an automatic compensation position mechanism for a welding strip positioning fixture for dense grid solar cells, so as to solve the problem of damage risks such as incomplete welding, over-welding, and exposed white areas that occur during the welding process between the welding strip and the solar cell as mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic position compensation mechanism for a welding strip positioning fixture for dense-grid solar cells, comprising a position compensation mechanism, wherein the position compensation mechanism includes a support structure, a transverse transmission mechanism fixed on the support structure, a transverse mounting plate fixedly installed on the top of the moving end of the transverse transmission mechanism, two mounting plates vertically fixed at both ends of the top of the transverse mounting plate, a blocking detection component fixed on one side of the mounting plate, a limit correction alignment block, a limit elevation block, a limit separation block, a blocking detection component fixed on the other side of the mounting plate, a movable correction alignment block, a limit elevation block, and a limit separation block. The high separation block, the blocking detection component is used to stop the fixture, and the fixture can only be positioned and the next step of correction, alignment and shaping can be realized after both sides of the fixture are in contact with the blocking detection component. The limiting correction and alignment block is the reference correction surface. The movable correction and alignment block is used to correct, correct and shape the fixture by opening and closing. The limiting shim block is used to guide the fixture to flow into the designated position and can lift the fixture to detach it from the belt to ensure that the correction, alignment and shaping are performed on a plane. The height limiting separation block is used to limit the height of the fixture to separate the front and rear fixtures after correction, alignment and shaping.

[0006] Preferably, the support structure comprises an adjustable mounting plate, a column connected at one end to the adjustable mounting plate, and a support plate connected at the other end of the column, with the transverse transmission mechanism mounted on the support plate.

[0007] Preferably, the transverse transmission mechanism consists of a servo motor, a lead screw connected to the output shaft of the servo motor, a sliding sleeve screwed onto the lead screw, two guide rails mounted on a support plate, and a slider slidably mounted on the guide rails, with the sliding sleeve and the slider both fixed to the bottom of the transverse mounting plate.

[0008] Preferably, the limit correction alignment block is located between the obstruction detection component and the height limit separation block, and the movable correction alignment block is located between the obstruction detection component and the height limit separation block.

[0009] Preferably, the obstruction detection component is used to block the fixture, and the fixture can only be positioned and the next step of correction, alignment, and shaping can be achieved after both sides of the fixture are in contact with the obstruction detection component. The limiting correction and alignment block is a reference correction surface, and the movable correction and alignment block is used to correct, straighten, shape, and position the fixture through opening and closing movements.

[0010] Compared with the prior art, the beneficial effects of this application are:

[0011] 1) Compared with previous mechanisms, this application realizes automatic adjustment and compensation in the front and rear directions to accommodate more battery cells for string welding, thereby enhancing the compatibility of the integrated battery cell dicing and string welding machine.

[0012] 2) In the string welding of solar cells in this application, when the cells are welded to the solder strip, the risk of damage such as incomplete welding, over-welding, and exposed white areas during the welding process is reduced. The automatic compensation and automatic correction of the position of the solder strip positioning fixture also reduces the defect rate caused by the welding of cells and solder strip by orders of magnitude.

[0019] Example:

[0020] Please see Figure 1-3 This application provides a technical solution: an automatic position compensation mechanism for a welding strip positioning fixture for dense grid solar cells, including a position compensation mechanism 100. Figure 1 The tooling fixture conveying mechanism 200 is used to convey the fixture 300. The position compensation mechanism 100 is installed on the tooling fixture conveying mechanism 200 to adjust and compensate the position of the fixture 300. The position compensation mechanism 100 includes a support structure, a transverse transmission mechanism 13 fixed on the support structure, a transverse mounting plate 14 fixedly installed on the top of the moving end of the transverse transmission mechanism 13, two mounting plates 15 vertically fixed at both ends of the top of the transverse mounting plate 14, a blocking detection component 16 fixed on one side of the mounting plate 15, a limit correction and alignment block 17, a limit elevation block 19, a height separation block 20, and a blocking detection component 16, a movable correction and alignment block 18, and a limit elevation block 19 fixed on the other side of the mounting plate 15. The height-limiting separation block 20; the blocking detection component 16 is used to prevent the fixture 300 from being positioned and to achieve the next step of correction, alignment, and shaping action only after the fixture 300 is simultaneously in contact with the blocking detection component 16 on both the left and right sides; the limiting correction and alignment block 17 is a reference correction surface; the movable correction and alignment block 18 is used to perform correction, alignment, shaping, and positioning of the fixture 300 through opening and closing movements; the limiting elevation block 19 is used to guide the fixture 300 to flow into the designated position and to lift the fixture 300 so that it is detached from the belt to ensure that correction, alignment, and positioning are performed on a plane; the height-limiting separation block 20 is used to limit the height of the fixture 300 to achieve separation of the front and rear fixtures 300 after correction, alignment, and positioning.

[0021] The support structure consists of an adjustable mounting plate 11, a column 12 connected to the adjustable mounting plate 11 at one end, and a support plate connected to the other end of the column 12. The transverse transmission mechanism 13 is mounted on the support plate. The adjustable mounting plate 11 can be adjusted slightly left and right during the alignment fixture conveying mechanism. The column 12 supports the entire welding strip positioning fixture automatic position compensation mechanism and can save space. The transverse transmission mechanism 13 is used to carry the position compensation mechanism 100 to achieve automatic adjustment in the front and rear directions to accommodate more battery cells for string welding.

[0022] The transverse transmission mechanism 13 consists of a servo motor, a lead screw connected to the output shaft of the servo motor, a sliding sleeve screwed onto the lead screw, two guide rails mounted on the support plate, and a slider slidably mounted on the guide rails. The sliding sleeve and the slider are both fixed to the bottom of the transverse mounting plate 14. The rotation of the servo motor drives the lead screw to rotate, and the rotation of the lead screw drives the sliding sleeve to move, thereby driving the transverse mounting plate 14 to move along the guide rails.
