Description

Technical Field

[0001] The present invention relates to the technical field of solar panel production, and in particular to a solar panel laser welding device. Background Art

[0002] Solar panels are the core components of photovoltaic power generation. They absorb sunlight and convert it into electrical energy. When processing solar panels, it is usually necessary to weld multiple solar panels together to form a photovoltaic power generation component. In order to avoid the welding slag generated by traditional welding methods that affects the quality of the solar panels, laser welding is usually used for welding.

[0003] The two solar panels to be welded need to be neatly placed on the processing table before welding, and then the staff manually operate the clamp to clamp them, which is a cumbersome operation. In addition, due to the manual control of the clamp to clamp the solar panels, it is easy to cause the clamping to be too loose, affecting the welding accuracy, and the clamping to be too tight, causing damage to the solar panels. At the same time, the solar panels are generally only clamped on two opposite sides, resulting in poor clamping effect, and the solar panels are easy to loosen, affecting the welding effect.

[0016] Compared with the prior art, the present invention provides a solar panel laser welding device with the following beneficial effects:

[0017] 1. The solar panel laser welding device controls the operation of the driving component so that the driving component drives the two main clamps to move relative to each other. When the driving component is working, it drives the transmission component to move, and the transmission component drives the two auxiliary clamps to move closer to each other. When the two auxiliary clamps move closer to each other, they push the two solar panels to be welded on the workbench to align the two solar panels to be welded. Then, the two main clamps clamp the aligned solar panels in the center, which is convenient for fast and automatic alignment and clamping positioning of the solar panels, improves the clamping efficiency of the solar panels, and then improves the laser welding efficiency of the solar panels, ensuring the laser welding quality of the solar panels.

[0018] 2. The solar panel laser welding device has an extrusion slope on the side of the main clamp close to the solar panel, so that the extrusion slope can simultaneously clamp and limit the side and top of the solar panel to be welded, thereby achieving multi-directional clamping and positioning of the solar panel, effectively preventing the solar panel to be welded from loosening, and ensuring the quality of subsequent laser welding of the solar panel.

[0019] 3. The solar panel laser welding device uses two main clamps to align and position two solar panels to be welded with the same structure. The two solar panels to be welded are moved under force and squeeze the inclined surface of the force-bearing block, so that the force-bearing block is forced to move downward in the slide groove. After the two solar panels to be welded are abutted, the force-bearing block squeezes the press switch, and the press switch controls the second motor to stop working, so that the two main clamps maintain the positioning and clamping state of the two solar panels to be welded, avoiding manual control of the main clamps to clamp the solar panels to be welded, resulting in too loose clamping affecting the welding accuracy, and too tight clamping damaging the solar panels.

A transmission assembly for driving the auxiliary clamping seats 4 to move horizontally is arranged at the bottom of the workbench 1 along its width direction.

[0032] Specifically, when welding two solar panels 2 with the same structure, first place the two solar panels 2 on both sides of the workbench 1 respectively, and then the staff controls the driving assembly to work through the control panel 101. When the driving assembly is working, it drives the main clamps 3 on both sides to approach each other, and the two main clamps 3 clamp the two solar panels 2 to be welded on the workbench 1. When the driving assembly is working, it drives the transmission assembly to move, and the transmission assembly drives the two auxiliary clamps 4 to approach each other. The two auxiliary clamps 4 are faster than the two main clamps 3 to abut against the sides of the solar panel body 2, so that the two solar panel bodies 2 are aligned and placed. Then the two main clamps 3 clamp and position the two aligned solar panels 2, and the welding assembly is placed directly above the joint of the two solar panel bodies 2, and the welding assembly performs welding action on the two joined solar panel bodies 2. This application facilitates the rapid and automatic alignment and clamping of the solar panel bodies 2, reduces the workload and difficulty of the staff, improves the clamping efficiency of the solar panel body 2, and thus improves the efficiency of laser welding of solar panels, ensuring the quality of laser welding of solar panels.

[0036] Furthermore, an outer wall of the main clamping seat 3 is provided with an extrusion slope 301 , and the extrusion slope 301 movably contacts the solar panel body 2 .

[0037] Specifically, when the driving component is working, the control panel 101 controls the operation of the second motor 601, and the output shaft of the second motor 601 drives the bidirectional screw 602 to rotate, so that the second sleeves 603 at both ends of the bidirectional screw 602 approach each other, and the second sleeve 603 drives the main clamping seat 3 to move through the first connecting plate 6031, so that the two main clamping seats 3 are clamped and positioned toward the solar panel body 2 placed on the workbench 1, and an extrusion slope 301 is opened on the side of the main clamping seat 3 close to the solar panel, so that the extrusion slope 301 simultaneously clamps and limits the side and top of the solar panel body 2 to be welded, thereby realizing multi-directional clamping and positioning of the solar panel, effectively avoiding loosening of the solar panel to be welded, and ensuring the quality of subsequent laser welding of the solar panel.

[0040] Furthermore, a slide groove 8 is provided on the workbench 1, and a force block 801 is slidably connected in the slide groove 8. A second elastic telescopic rod 802 is provided between the force block 801 and the inner wall of the slide groove 8.

The auxiliary clamping seat 4 and the solar panel body 2 are closer than the main clamping seat 3 and the solar panel body 2. The auxiliary clamping seat 4 first abuts against the side of the solar panel body 2, so that the auxiliary clamping seat 4 pushes the solar panel body 2 and aligns it. As the driving assembly continues to operate, the main clamping seat 3 begins to abut against the solar panel body 2, the first elastic telescopic rod 402 is forced to shrink, and the distance between the second plate body 403 and the first plate body 401 is shortened until the main clamping seats 3 on both sides squeeze the two solar panel bodies 2 in the center, and the two solar panels are 2 applies thrust to the force-bearing block 801, the force-bearing block 801 moves downward in the slide groove 8, the second elastic telescopic rod 802 is compressed, and the force-bearing block 801 then abuts against the press switch 9, and the press switch 9 controls the second motor 601 to stop running, avoiding manual control of the main clamp 3 to clamp the solar panel body 2 to be welded, resulting in the situation that the clamping is too loose and affects the welding accuracy, and the clamping is too tight and damages the solar panel. The press switch 9 synchronously controls the second electric push rod 11 to work, so that the second electric push rod 11 drives the plug 111 to move downward, and the plug 111 is plugged into the rack plate 12 on the workbench 1 to position the second plate body 403 at this time, maintaining the auxiliary clamp 4 against the solar panel body 2. After pushing the solar panel body 2 to align, the multi-directional positioning of the solar panel body 2 is further realized, effectively avoiding the loosening of the solar panel to be welded, and ensuring the subsequent laser welding quality of the solar panel.
