Description

Technical Field

[0001] This invention relates to the photovoltaic field, and more specifically to a tooling for bonding multi-silicon blocks. Background Technology

[0002] Crystalline silicon solar cells are made from silicon wafers; silicon wafers can be obtained by slicing a rod-bonding module (i.e., a whole rod) by splicing and bonding silicon blocks (such as square rods). Currently, the rod bonding process in the photovoltaic industry is mainly based on manual splicing and bonding, and generally two square rods are used to complete the bonding of the whole rod to meet the requirements of rapid rod bonding. However, with the development of photovoltaic technology, half-cell and small-cell silicon wafer technologies have emerged; and when manufacturing half-cells and small-cells, it is often necessary to use a large number of silicon blocks to splice and bond into a whole rod; this requires the design of a tooling suitable for bonding multiple silicon blocks into rods.

[0041] This invention also provides a method for using the above-mentioned tooling for attaching multi-silicon blocks, comprising the following steps:

[0042] 1) Place the silicon tray flat on the base plate of the tooling, and make the silicon tray abut against the positioning pin on the top surface of the base plate to achieve horizontal positioning of the silicon tray.

[0043] 2) Then apply adhesive to the top surface of the silicone tray;

[0044] 3) Then place the plastic carrier plate flat on the rubber surface of the silicone tray (i.e., the top surface of the silicone tray); then activate the first quick clamping device, so that the first push rod of the first quick clamping device extends to the limiting side, and the first push rod pushes the carrier plate to the limiting side, so that the carrier plate is pressed against the adjusting screw, thereby achieving horizontal positioning and fixed clamping of the carrier plate.

[0045] 4) After the adhesive has fully cured (i.e. the carrier board and the silicone tray are bonded together), apply adhesive stick to the top surface of the carrier board.

[0046] 5) Then, at least two rows of silicon block groups are placed on the adhesive surface of the carrier plate (i.e., the top surface of the carrier plate); the silicon block group is composed of a row of silicon blocks spliced ​​together; the rows of silicon block groups on the carrier plate are arranged side by side, and a partition is inserted between adjacent rows of silicon block groups; the two outermost rows of silicon block groups are respectively: the limiting side silicon block group near the bottom plate limiting side, and the pressure side silicon block group near the bottom plate pressure side;

[0047] 6) Then activate the second quick clamping device, so that the second push rod of the second quick clamping device extends to the limiting side. The second push rod directly pushes the support rod to move horizontally to the limiting side. The support rod drives the pressure rod to move horizontally to the limiting side. The pressure rod pushes the silicon block group on the pressure side to the limiting side, so that each row of silicon block groups is clamped by the pressure rod and the limiting rod, thereby achieving horizontal positioning and fixed clamping of each row of silicon block groups.

[0048] 7) Place a weight (such as a weight) on the top surface of each row of silicon blocks. At this time, the fixture carries the sticking rod assembly consisting of silicon support, carrier plate, silicon block assembly and separator. Then transport the fixture and the sticking rod assembly (i.e. the whole rod) it carries to the next station (such as the slicing station).

[0049] After the adhesive has fully cured (i.e., each row of silicon blocks is bonded to the carrier), the adhesive rod assembly (i.e. the whole rod) is sliced.

[0050] The adhesive rod assembly (i.e., the whole rod) on the tooling can be sliced ​​directly;

[0051] Before slicing, you can unlock the locking mechanism / locking bar, turn the flipping frame outward and flatten it, remove the adhesive stick assembly (i.e., the whole stick) from the fixture, and then slice the adhesive stick assembly (i.e., the whole stick) separately.
