Embodiment 1

[0044] The invention provides a needle pressing mechanism of a stringer welding machine, such as Figure 1-10 As shown, it includes: pressure needle bar support 1, pressure needle bar 2, pressure needle 3, spring 4 and welding ribbon press net 5; wherein, the stringer welder uses welding belt press net 5 to press the welding ribbon, and welding ribbon press net 5 It is set above the welding ribbon to press the welding ribbon to prevent the ribbon from shifting during the welding process of the battery sheet; the pressure pin 3 is used to provide downward pressure to compress the welding ribbon to ensure that the battery sheet is welded into a battery string through the welding ribbon During the process, there will be no false welding phenomenon, which ensures the welding quality of the stringer. The spring 4 is arranged between the indenter 3 and the indenter bar 2, and is used for buffering the impact of the indenter 3 on the welding ribbon. After the spring 4 is compressed, ...

Embodiment 2

[0074] A stringer, using the stringer mechanism in Embodiment 1 to press the ribbon.

Embodiment 3

[0076] A method for compressing the welding strip of a stringer, characterized in that the needle pressing mechanism of the stringer according to Embodiment 1 is adopted, comprising the following steps:

[0077] Step S1: Rotate the second cylinder (322) to move up or down relative to the first cylinder (321), and adjust the length of the pressing needle (3);

[0078] Step S2: the pressing needle (2) moves down to drive the pressing needle (3) to move downward, and the pressing needle (3) contacts the welding strip;

[0079] Step S3: Continue to move down the needle bar (2) to compress the spring (4).

[0080] Before adjusting the length of the indenter 3, install the indenter 3 on the indenter bar 2. Specifically, the installation method of the indenter 3 on the indenter bar 2 is:

[0081] First, the spring 4 is sleeved on the outside of the pressing needle body 32;

[0082] Furthermore, the indenter main body 32 is inserted into the indenter installation hole 24 from below ...

Abstract

The invention relates to a pin pressing mechanism of a stringer, a stringer and a pressing method thereof, which belong to the field of photovoltaic module processing and production, and solve the problems in the prior art that it is difficult to adjust the position of the welding pin and the replacement process of the soldering pin is cumbersome. The needle pressing mechanism of the present invention comprises: a needle pressing bar support, a needle pressing bar, a pressing needle, and a spring; wherein the needle pressing bar is fixedly installed on the needle pressing bar support, and the pressing needle is installed on the needle pressing bar, driven by the needle pressing bar support Move down, the indenter is used to provide downward pressure to compress the welding ribbon. The length of the indenter of the present invention is adjustable and has good applicability, and a spring is arranged between the indenter and the indenter bar, and the compression amount of the spring can be adjusted. The pressure is aimed at the size of the pressing force of the ribbon to avoid the phenomenon of virtual welding when the battery sheet is welded by the ribbon. The invention realizes quick replacement of welding pressing pins and flexible adjustment of the height of the pressing pins.

Description

technical field [0001] The invention relates to the technical field of stringer welding machines, in particular to a stringer welding machine pressing needle mechanism, a stringer welding machine and a pressing method thereof. Background technique [0002] At present, a stringer is generally used in the manufacture of solar cells. The tooling of the stringer is an integrated welding pin holder. When the welding pin needs to be replaced during use, it needs to be disassembled as a whole, which increases the problem processing time and the degree of fatigue. . [0003] In addition, there are certain disadvantages when adjusting the position of the welding pins. It is necessary to adjust the position of the cell on the welding bracket or the bracket pins need to be reinstalled. [0004] The length of the currently used welding indenter is 2cm, and the problem of hitting the welding belt on the pressing net during the pressing process of the welding lifting mechanism frequently...
