Description

TECHNICAL FIELD

[0001] The utility model belongs to cutting equipment technical field, especially a kind of automatic deviation rectifying laser cutting device for cutting sheet in photovoltaic industry.

BACKGROUND

[0002] In the production process of photovoltaic cells, the battery piece needs to be laser cut to realize the piece of battery piece. The battery piece cutting operation requires the position of the battery piece to have high precision. In order to ensure the high-precision cutting operation of the battery piece, many methods are proposed in the prior art. Among them, patent CN118989675A discloses a stringer that integrates cell deviation rectification, transmission, laser scribing and post-scribing detection. A vision camera is provided upstream of the cutting station to obtain the position of the battery piece. A deviation rectification platform is also provided at the station. According to the position information obtained by the vision camera, the position of the battery piece is rectified. Then, a lifting translation mechanism is used to translate the rectified battery piece under the laser cutting head to achieve precise scribing. However, the battery piece needs to be transferred to the next station after completing the position rectification at the vision rectification station, which is low in efficiency.

[0003] In addition, patent CN222269056U discloses a laser cutting assembly and a photovoltaic stringer with the same. The laser cutting assembly has a parallelly arranged feeding conveying line and a cutting and transferring module. A camera is provided on the feeding conveying line to obtain the position of the battery piece. Then, a carrying mechanism with deviation rectification is used to carry the battery piece on the feeding conveying line to the cutting and transferring module. The position of the battery piece is rectified and adjusted during the carrying process. The cutting and transferring module receives the battery piece to translate under the laser cutting head to achieve precise scribing. However, the carrying path of the carrying mechanism in this structure is long, and the idle time is relatively long, which also reduces the production efficiency.

[0004] Therefore, it is necessary to provide a new automatic deviation rectifying laser cutting device to solve the above technical problems.

[0035] The removal and deviation correction mechanism 4 comprises an X-axis driving module 41, a third support plate 45 driven by the X-axis driving module 41 to move left and right horizontally, a Z-axis driving module 46 fixed on the third support plate 45, a first support plate 42 driven by the Z-axis driving module 46 to move up and down, a deviation correction driving module 43 fixed on the first support plate 42, and a suction support platform 44 driven by the deviation correction driving module 43 to adjust the angle of the battery piece 200 to a set state.

[0036] The X-axis driving module 41 drives the adsorption support platform 44 to reciprocate with the battery piece between the photographing station and the receiving platform 5, and cooperates with the laser cutting mechanism 2 to realize the cutting operation of the battery piece. The Z-axis driving module 46 drives the adsorption support platform 44 to move up and down to realize the transfer of the battery piece between the conveying line 1 and the adsorption support platform 44, and between the adsorption support platform 44 and the receiving platform 5. The deviation correction driving module 43 drives the adsorption support platform 44 to adjust the horizontal angle to realize the angle adjustment of the battery piece, so that it passes through the laser cutting mechanism 2 according to the set angle posture.

[0037] In the embodiment, the adsorption support platform 44 is rotatably arranged on the first support plate 42, and the deviation correction driving module 43 includes a first driving member 431 fixed on the first support plate 42 and driving the adsorption support platform 44 to rotate. The rotary transmission of the first driving member 431 can adopt belt transmission or gear and rack meshing transmission, or direct driving of a rotary motor, which is not limited in the embodiment.

[0038] In the embodiment, two transmission belts 11 are arranged, and the adsorption support platform 44 is provided with an avoidance through slot 441 avoiding the transmission belts 11, which penetrates left and right. In other embodiments, more transmission belts 11 can be arranged, which is mainly designed flexibly according to the size of the incoming battery piece.

[0039] The adsorption support platform 44 includes a plurality of parallel and spaced support rods 443, and the avoidance through slot 441 is formed between adjacent two support rods 443. The surface of the support rod 443 is provided with a plurality of adsorption holes 442 adsorbing the battery piece.

[0040] The deviation correction driving module 43 and the adsorption support platform 44 jointly constitute a deviation correction support module, and at least two groups of deviation correction support modules are arranged on the first support plate 42.
