Embodiment 1

[0037] A specific embodiment of the present invention discloses a retractable mechanism for a PTFE cloth pad installed at the position of the welding head of a stitch welding machine, such as Figure 1-Figure 2 As shown, it includes: base plate 3, guide column 4 installed on the base plate 3, fixed block 5 and tetrafluoro tape reel for fixing the whole retractable mechanism on the welding head bracket 13, and four fluoro tape reels are wound in the tetrafluoro tape reel Fluorine fabric roll is PTFE tape 2. Two PTFE tape reels are installed at the two ends of the welding head support 13, wherein, a PTFE tape reel is used as a discharge tape reel, and another PTFE tape reel is used as a receiving tape reel, by rotating two PTFE tape reels, can Make the tetrafluoro tape 2 slide relative to the welding head 15 to complete the replacement of the tetrafluoro tape 2 .

[0038] Specifically, two fixed blocks 5 are installed at the two ends of the welding head support 13, and the two ...

Embodiment 2

[0061] A lap welding machine, the PTFE pad retractable mechanism in Example 1 is installed on the welding head bracket, used to replace the PTFE cloth pad on the welding head 15, instead of manually pasting the four fluoro cloth pads on the welding head. Operation of fluorocloth tape.

Embodiment 3

[0063] A method for replacing the tetrafluoro cloth gasket of welding head of a lap welding machine, adopting the tetrafluoro cloth gasket retractable mechanism in embodiment 1 to replace the tetrafluoro cloth gasket, the method for replacing the tetrafluoro cloth gasket includes the following steps:

[0064] Step S1: Install the retractable mechanism of the PTFE pad on the welding head bracket 13 of the stitch welding machine;

[0065] Step S2: When the PTFE cloth needs to be replaced, open the fixed ring 10; rotate the PTFE tape reel to take in and out the material, and the tape reel is used to discharge the material while the tape reel is receiving the material to complete the PTFE cloth retracting and unwinding;

[0066] Step S3: Lock the fixing ring 10, and now the PTFE tape reel rotates; the PTFE tape 2 is tensioned on the welding head 15.

[0067] In the step S1, the tetrafluoro tape 2 is wound on the first tape reel 1, and the end of the tetrafluoro tape 2 is fixedly c...

Abstract

The invention relates to a teflon cloth filler strip retracting and releasing mechanism, a stitch welding machine and a filler strip replacing method, belongs to the technical field of photovoltaic module production and processing. The problems that in the prior art, teflon cloth needs to be manually stretched into stitch welding machine equipment, a welding head needs to be detached and replaced, operation is inconvenient, and potential safety hazards exist are solved. According to the teflon cloth filler strip retracting and releasing mechanism, teflon tape reels are arranged at the two ends of a welding head support, teflon tape cloth rolls are wound on the teflon tape reels, one of the two teflon tape reels serves as a feeding tape reel, and the other one of the two teflon tape reels serves as a receiving tape reel; a guide column is arranged in a gap between every two adjacent welding heads; the unfolded part of the teflon tape bypasses the guide column and is attached to the bottom surface of the welding head. When teflon tape needs to be replaced, the teflon tape reel is rotated, the feeding tape reel is used for discharging, and at the same time the receiving tape reel is used for receiving materials; the teflon tape on the welding head is replaced, so that teflon tape replacement outside equipment is achieved, manual teflon tape pasting is replaced, and abnormal pseudo soldering caused by incomplete cleaning of adhesive tape residual adhesive can be avoided.

Description

technical field [0001] The invention relates to the technical field of processing and production of optical group components, in particular to a retractable mechanism for tetrafluoro cloth pads, a stitch welding machine and a pad replacement method. Background technique [0002] With the continuous update and development of technology, the process of photovoltaic modules is changing with each passing day. Processes such as multi-grid half-cut modules and double-sided double-glass modules have gradually won the market's recognition for their excellent conversion efficiency. Half-cut modules have doubled the number of cells, and the batteries are connected in series. The time will also be doubled. The difficulty is that the lead-out line of the busbar is led out from the middle of the back of the module. If it is manually operated, it will increase the risk of battery splits or hidden cracks at the leadout line. Currently, the busbar welding of the lead-out line in the middle o...
