Embodiment 1

[0038] like figure 1 and 2 As shown, a cell pressure welding device includes a pressure welding base 3-1, a pressure welding horizontal adjustment assembly, a pressure welding bracket 3-2, a pressure welding lifting slide table 3-10, a lifting drive assembly, and a pressure welding support plate 3 -3 and welding mechanism 3-4. The bottom of the pressure welding bracket 3-2 and the top surface of the pressure welding base 3-1 form a sliding pair. The press-welded lateral adjustment assembly includes an adjustment seat 3-5, an adjustment screw rod 3-6 and an adjustment nut block 3-7. Two adjustment seats 3-5 are fixed on the pressure welding base 3-1. Adjusting screw rod 3-6 and two adjusting seats 3-5 constitute a revolving pair. The adjusting nut block 3-7 is fixed on the bottom of the pressure welding support 3-2, and forms a spiral pair with the adjusting screw rod 3-6. The lateral position of the adjusting seat 3-5 can be adjusted by turning the adjusting screw rod 3-6...

Embodiment 2

[0050] like Figure 4 As shown, the cell string pressure welding device is used to produce "IBC solar cell string". The structure of the IBC solar cell string is as follows figure 1 As shown, it includes six cells A and multiple ribbons B. Each battery sheet A is arranged at equal intervals in turn. Two adjacent cells A are connected by a set of ribbons B. There are four welding ribbons B in one set, and they are arranged along the direction vertical to the arrangement of battery sheets. The two ends of the four welding ribbons B respectively cover the opposite edges of the two adjacent battery sheets A. Adjacent two groups of soldering strips are staggered; therefore, any battery sheet A is connected with eight soldering ribbons B. There are four welding ribbons B covering only one battery piece on the battery piece A at the head end and the tail end respectively. During use, the welding ribbon can be placed on the designated position of the battery piece after each bat...

Abstract

The invention discloses a cell sheet pressure welding device, a battery series pressure welding device and a welding method thereof. Soldering equipment used for solar cells is difficult to ensure the uniformity of welding. A battery slice pressure-welding device, comprising a pressure-welding base, a pressure-welding bracket, a pressure-welding lifting slide table, a lifting drive assembly, a pressure-welding support plate and a welding mechanism. The pressure welding support plate is fixed on the pressure welding support. The pressure-welding lifting slide table and the pressure-welding support form a sliding pair. The pressure welding lifting slide table is driven by the lifting drive assembly. The welding mechanism is located directly above the pressure welding support plate and includes the diaphragm replacement assembly and four welding units. The welding unit includes a single bracket, an X-axis adjustment assembly, a Y-axis adjustment assembly, a gas spring and a pressure welding head. Diaphragm replacement components include diaphragm support, output drum, recovery drum, coiled diaphragm, and unwinding drive assembly. The welding mechanism of the present invention has the capability of turning over and adjusting in two directions, and through correction, it can ensure that the pressure welding head is parallel to the pressure welding support plate, thereby reducing the occurrence of welding defects.

Description

technical field [0001] The invention belongs to the technical field of solar cell production equipment, and in particular relates to a cell sheet pressure welding device, a battery series pressure welding device and a welding method thereof. Background technique [0002] IBC battery (full back electrode contact crystalline silicon photovoltaic cell) is a technology that moves both the positive and negative metal contacts to the back of the cell, so that the front of the cell facing the sun is completely black, and the front of most photovoltaic cells is completely invisible. metal wire. This not only brings more effective power generation area to users, but also helps to improve power generation efficiency, and the appearance is also more beautiful. The biggest feature of the IBC battery is that the PN junction and metal contact are on the back of the battery, and the front is not affected by the shielding of the metal electrode, so it has a higher short-circuit current Jsc...
