[0002] The stringer uses a mechanical transmission mechanism to transport the battery cells, and uses the high-temperature gas from the hot air pipe on the heated base to weld the battery cells. When the photovoltaic stringer is welding the photovoltaic panels, it is necessary to use an auxiliary loading mechanism to assist in loading the photovoltaic panels.

[0003] For example, the Chinese patent publication number CN219944886U discloses a photovoltaic panel material taking device for string welding machine processing, including two groups of support frames, the tops of the two groups of support frames are fixedly installed with a conveying mechanism, one side of the conveying mechanism is fixedly installed with a working frame, the inside of the working frame is fixedly installed with a turning mechanism, the bottom of the turning mechanism is fixedly installed with a taking mechanism, and one side of the taking mechanism is fixedly installed with an auxiliary unloading mechanism for convenient unloading of photovoltaic panels;

[0004] In the prior art, a conveying mechanism is provided to drive the picking mechanism to move in the left and right and up and down directions, so as to complete the loading and unloading of photovoltaic panels. Then, the flipping mechanism can drive the picking mechanism and the photovoltaic panel to flip to a certain angle, and then they can contact with the auxiliary unloading mechanism. Then, the picking mechanism releases the photovoltaic panel, and the conveying mechanism can drive the photovoltaic panel to move and descend, while the auxiliary unloading mechanism can always contact with the photovoltaic panel, and then the flipping and picking of the photovoltaic panel can be completed.

When the panels are adsorbed by the vacuum nozzle in the loading mechanism, there is a deviation from the processing station on the stringer, and manual correction is required, which has a great impact on the subsequent photovoltaic panel stringing processing.

[0013] Preferably, the four groups of positioning plates are respectively located in the corresponding inner walls of the clearance grooves.

[0014] Preferably, the four groups of positioning plates are respectively fixedly mounted on the corresponding telescopic ends of the positioning cylinders.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model uses four sets of side guard plates to slide up and down in the electric slide on the inner wall of the feeding support seat through the outer matching slider, so that the rectangular structure composed of the four sets of side guard plates can slide upward to adjust the height of the side guards, thereby providing certain protection for the photovoltaic panels stacked at a certain height, and the positioning plates on the inner sides of the side guard plates are synchronously telescopically adjusted by the positioning cylinders, so that the photovoltaic panels stacked around can be placed straightened, so that when the vacuum suction nozzle on the support frame adsorbs and feeds the photovoltaic panels, the photovoltaic panels after being straightened can be adsorbed, and the photovoltaic panels with accurate adsorption positions are convenient for subsequent welding operations on the string welding machine;

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-4 The utility model provides a technical solution: an auxiliary feeding mechanism of a photovoltaic string welding machine, comprising a support frame 1, a vacuum nozzle 2, and a feeding support seat 3, a side skirt plate 4 is fixedly installed on the top of the feeding support seat 3, a feeding plate 5 is arranged inside the side skirt plate 4, and side guard plates 6 are movably inserted around the inside of the side skirt plate 4;

[0025] Matching slide blocks 62 are fixedly installed on the outer sides of the four sets of side guard plates 6 near the bottom, and a lifting cylinder 7 is fixedly installed in the inner wall of the loading support seat 3. Positioning plates 8 are respectively arranged near the top of the inner sides of the four sets of side guard plates 6, and positioning cylinders 9 are respectively fixedly installed on the outer sides of the four sets of side skirt plates 4 near the top;

[0026] The slide rail on the support frame 1 can move the photovoltaic panel adsorbed on the vacuum nozzle 2 to load the photovoltaic panel, so as to load the photovoltaic panel to the string welding machine for welding. The photovoltaic panel loading is an existing technical solution and will not be described in detail here.

[0027] The electric slide 31 is a ball screw slide, model sr150;

[0028] The four groups of side guard plates 6 can slide up and down in the electric slide 31 on the inner wall of the loading support seat 3 through the outer matching sliders 62, so that the rectangular structure composed of the four groups of side guard plates 6 can slide upward to adjust the side guard height, thereby providing certain protection for the photovoltaic panels stacked at a certain height, and the positioning plates 8 on the inner sides of the side guard plates 6 are synchronously telescopically adjusted by the positioning cylinders 9, so that the stacked photovoltaic panels can be straightened and placed around. In this way, when the vacuum suction nozzle 2 on the support frame 1 adsorbs and feeds the photovoltaic panels, it can adsorb the straightened photovoltaic panels, and the photovoltaic panels with precise adsorption positions are convenient for subsequent welding operations on the stringing machine. Compared with the existing photovoltaic panels stacked on the feeding plate 5, which have the problem of incorrect placement and deviation, the stacked photovoltaic panels can be automatically straightened, ensuring that the photovoltaic panels adsorbed and fed by the vacuum suction nozzle 2 in the feeding mechanism are accurately placed, which is convenient for subsequent stringing processing of the photovoltaic panels.

[0029] Among them, electric slides 31 matching matching sliders 62 are fixedly installed around the inner wall of the loading support seat 3, and the matching sliders 62 on the outer sides of the four groups of side guard plates 6 slide on the corresponding electric slides 31 respectively. The bottom of the loading plate 5 movably penetrates into the inner wall of the loading support seat 3, and the telescopic end of the lifting cylinder 7 is fixedly connected to the bottom of the loading plate 5. The four groups of side guard plates 6 can slide up and down in the electric slide 31 on the inner wall of the loading support seat 3 through the outer matching sliders 62, so that the rectangular structure composed of the four groups of side guard plates 6 can slide upward to adjust the side protection height, so as to provide certain protection for the photovoltaic panels stacked at a certain height. The telescopic end of the lifting cylinder 7 can lift and support the loading plate 5 along the rectangular space composed of the four groups of side guard plates 6, so that the photovoltaic panels after stacking can be lifted to the position below the vacuum suction nozzle 2, which is convenient for the vacuum suction nozzle 2 to adsorb and load the stacked photovoltaic panels one by one.

[0030] Among them, positioning grooves 61 are respectively arranged around the inner wall of the side skirt plate 4, and the four groups of side guard plates 6 are respectively inserted into the corresponding inner walls of the positioning grooves 61, and the inner sides of the four groups of side guard plates 6 are respectively provided with clearance grooves 81 near the top. The four groups of positioning plates 8 are respectively located in the corresponding inner walls of the clearance grooves 81, and the four groups of positioning plates 8 are respectively fixedly installed on the telescopic ends of the corresponding positioning cylinders 9. The four groups of side guard plates 6 can slide up and down in the electric slide 31 on the inner wall of the feeding support seat 3 through the outer matching sliders 62, so that the rectangular structure composed of the four groups of side guard plates 6 can slide upward to adjust the side protection height, so as to provide certain protection for the photovoltaic panels stacked at a certain height. The positioning plates 8 on the inner sides of the side guard plates 6 are synchronously telescopically adjusted by the positioning cylinders 9, so that the stacked photovoltaic panels can be placed upright around them. In this way, when the vacuum suction nozzle 2 on the support frame 1 adsorbs and feeds the photovoltaic panels, it can adsorb the photovoltaic panels after being uprighted.

[0031] Working principle: When the photovoltaic panels are stacked and loaded, the photovoltaic panels are first placed on the loading plate 5 on the top of the loading support seat 3, and then the matching slider 62 on the electric slide 31 and the corresponding side guard plate 6 slide upward by a photovoltaic panel spacing. At this time, the positioning plate 8 on the inner side of the side guard plate 6 is synchronously telescopically adjusted by the positioning cylinder 9, so that the stacked photovoltaic panels can be straightened and placed around;

[0032] By analogy, the rectangular structure composed of four groups of side guard plates 6 can slide upward to adjust the height of the side guards, thereby providing certain protection for the photovoltaic panels stacked at a certain height, and the positioning plates 8 on the inner sides of the side guard plates 6 are synchronously telescopically adjusted by the positioning cylinders 9, so that the stacked photovoltaic panels can be straightened and placed around them. In this way, when the vacuum suction nozzle 2 on the support frame 1 adsorbs and feeds the photovoltaic panels, it can adsorb the straightened photovoltaic panels, and the photovoltaic panels with precise adsorption positions are convenient for subsequent welding operations on the stringing machine. Compared with the existing photovoltaic panels stacked on the feeding plate 5, there are problems of improper placement and deviation.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
