[0016] See also Figure 1 and Figure 2 , the utility model embodiment includes:
[0017] A photovoltaic welding strip correction device, the photovoltaic welding strip correction device comprises: a correction seat 2, a correction pressure plate and an adjustment bolt 6, the correction seat 2 comprises a correction seat body 201, a guide wheel bracket 202 is installed at one end of the correction seat body, a photovoltaic welding strip guide wheel 3 is installed on the guide wheel bracket 202, a correction seat mounting plate 203 is arranged at the other end of the correction seat body 202, the correction seat mounting plate 203 and the correction seat body 201 are perpendicular to each other, the correction seat mounting plate 203 is provided with a bolt fixing hole, and the entire photovoltaic welding strip correction device can be fixed with bolts. Four welding strip rollers 203 are installed in parallel on the correction seat body 201, three welding strip pressure rollers are installed on the correction pressure plate, and the positions of the welding strip rollers 206 and the welding strip pressure rollers are staggered. The correction platen is divided into two parts, one is the main platen 5, and the other is the auxiliary platen 4, wherein two main welding belt pressure rollers 501 are arranged in parallel on the main platen 5, and an auxiliary welding belt pressure roller 401 is arranged on the auxiliary platen 4, and a group of main adjustment bolt sockets 502 are arranged at both ends of the main platen 5, and the auxiliary platen 4 is arranged between the main platen 5 and the guide wheel bracket 202, and a group of auxiliary adjustment bolt sockets 402 are arranged on the auxiliary platen 4, and the auxiliary adjustment bolt sockets 402 are arranged at the end away from the main platen 5. The holes 402 are all through light holes. Each main adjustment bolt socket 502 and the auxiliary adjustment bolt socket 402 are provided with corresponding adjustment bottom holes 205 on the correction seat body 201 directly below. The adjustment bottom holes 205 are internal threaded holes. The end of the adjustment bolt 6 passes through the main adjustment bolt hole 502 and is connected to the lower adjustment bottom hole 205, so that the main pressure plate 5 and the correction seat body 201 are pressed together. The end of the adjustment bolt 6 passes through the auxiliary adjustment bolt hole 402 and is connected to the lower adjustment bottom hole 205, so that the auxiliary pressure plate 4 and the correction seat body 201 are pressed together. In this way, by dividing the correction pressure plate into two pieces, two-stage adjustment of the correction degree can be achieved, so that the correction can be adjusted in stages according to the degree of buckling of the photovoltaic welding strip 1, thereby improving the precision of the correction. In actual use, the main pressure plate 5 can be adjusted first. If the main pressure plate 5 is adjusted to the extreme position, the auxiliary pressure plate 4 can be adjusted as needed.

[0019] The working principle of the utility model is as follows:
[0020] After testing the produced photovoltaic welding tape 1, if it is found that there is a problem of bending to one side, the rolled photovoltaic welding tape can be unrolled through the gap between the correction seat 2 and the correction pressure plate, and then the adjusting bolt 6 is used to insert it into the main adjusting bolt hole 502. By adjusting the adjusting bolt 6, the tightness between the main pressure plate 5 and the correction seat 2 below is adjusted to make the pressure on both sides of the main pressure plate 5 unequal, thereby prompting the photovoltaic welding tape 1 to bend in the opposite direction when unrolling, offsetting the curvature of the photovoltaic welding tape 1 itself. During the adjustment process, the main pressure plate 5 is used to adjust according to the curvature. If the curvature is relatively large and the main pressure plate 5 has reached the limit position, the auxiliary pressure plate 4 can be further used to adjust at the same time, so as to finally achieve the purpose of straightening.
