Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component production, and particularly relates to a photovoltaic component lead shaping module and equipment. [Background technology]

[0002] One of the processes in the production of photovoltaic modules is the assembly of the junction box. The junction box needs to be welded to the leads on the photovoltaic module to achieve electrical connection. There are generally three pairs of leads in a photovoltaic module, and each pair of leads needs to remain basically vertical so that they can be inserted into the slots of the junction box and welded to the terminals in the junction box. However, during the production process, before the junction box is assembled, the state of the leads on the photovoltaic module is uneven. Therefore, in order to ensure the accurate and efficient assembly of the junction box, the leads need to be shaped and corrected to keep them basically vertical.

[0003] The prior art patent publication number CN116967373A discloses a photovoltaic module lead shaping mechanism and shaping method. During shaping, two clamps are first used to hook the lead from the outside of the lead to make it slightly tilted inward, and then a wire-pulling piece is inserted into the middle of the lead, and then two wire-pressing columns are used to press the root of the lead, and then the wire-pulling piece is moved from bottom to top to shape the lead to a basically vertical state. This method is a straightening action along the lead body. After a single shaping action is completed, the lead will still rebound and cannot stay in a basically vertical state for a long time, and the shaping effect needs to be improved.

[0004] Therefore, it is necessary to provide a new photovoltaic module lead shaping module and equipment to solve the above technical problems. [Contents of the utility model]

[0030] Embodiment 1:

[0031] Please refer to Figure 1-Figure 8 The present embodiment is a photovoltaic module lead shaping device 100, which includes a module conveyor line 1, an X-axis transfer module 2 located on the module conveyor line 1, a plurality of Y-axis transfer modules 3 arranged on the X-axis transfer module 2 for Y-axis transfer, a first support plate 4 arranged at the movable end of the Y-axis transfer module 3, and a lead shaping module 6 arranged on the first support plate 4.

[0032] The component conveyor line 1 is provided with a correction module 5 for correcting the position of the photovoltaic components.

[0033] In this embodiment, multiple lead shaping modules 6 share the same X-axis transfer module 2; each lead shaping module 6 is individually configured with a Y-axis transfer module 3, which can adjust its Y-direction position according to the position of each group of leads when the photovoltaic module is received.

[0034] In this embodiment, both the X-axis transfer module 2 and the Y-axis transfer module 3 use motor-driven gears and racks to achieve linear transfer. In other embodiments, the X-axis transfer module 2 can also use belt or chain transmission to achieve linear transfer.

[0035] In this embodiment, three lead shaping modules 6 are provided, corresponding to the three pairs of leads on the photovoltaic module.

[0036] The lead shaping module 6 includes a camera 61 for taking pictures of the lead positions on the photovoltaic module, a Z-axis transfer module 62 fixed on the first support plate 4, a second support plate 63 driven by the Z-axis transfer module 62 to move up and down, a servo motor 64 fixed on the second support plate 63, a pair of hammering components 65 arranged relatively front and back on the lower surface of the second support plate 63 and driven by the servo motor 64 to move closer to and apart from each other, and a first limit component 66 and a second limit component 67 arranged relatively left and right on the lower surface of the second support plate 63.

[0037] The servo motor 64 drives a pair of hammering assemblies 65 to move relative to each other through a screw-nut motion pair, so as to achieve position switching of the hammering assemblies 65 between a hammering working position and an avoidance position.

[0038] The first limiting assembly 66 includes a first cylinder 661 fixed on the second supporting plate 63 and a first limiting block 662 driven by the first cylinder 661 to move left and right.

[0039] The second limiting assembly 67 includes a second cylinder 671 fixed on the second support plate 63 and a second limiting block 672 driven by the second cylinder 671 to move left and right.

[0040] When the first limit block 662 and the second limit block 672 are in the close state, they jointly form an inner support limit surface 663 that extends into between the two leads to provide limit support for the inner surfaces of the two leads, left and right limit surfaces 664 that limit the left and right positions of the two leads to keep them in a vertical state aligned with the roots, and a movable cavity 665 for the hammering assembly 65 to hammer the leads.

[0041] The first limiting block 662 includes a first vertical plate 6621 and a first inner supporting block 6622 extending horizontally from the inner surface of the first vertical plate 6621 ; the second limiting block 672 includes a second vertical plate 6721 and a second inner supporting block 6722 extending horizontally from the inner surface of the second vertical plate 6721 .

[0042] The ends of the first inner support block 6622 and the second inner support block 6722 are both configured as pointed structures, so as to facilitate smooth insertion between the two lead wires.

[0043] When the first limit block 662 and the second limit block 672 are in the close state, the first inner support block 6622 is located directly below the second inner support block 6722, and the front and rear side surfaces of the first inner support block 6622 and the second inner support block 6722 together form the inner support limit surface 663; the movable cavity 665 is formed between the two opposite surfaces of the first vertical plate 6621 and the second vertical plate 6721, and at the same time, the two opposite surfaces form the left and right limit surfaces 664.

[0044] In order to facilitate the first limiting block 662 and the second limiting block 672 to be as close to each other as possible and to make the distance between them close to the lead width, in this embodiment, an avoidance hole 6623 for the second inner support block 6722 to be inserted is provided on the first vertical plate 6621, and at the same time, an avoidance groove 6723 for the first inner support block 6622 to be inserted is provided on the second vertical plate 6721.

[0045] The hammering assembly 65 includes a slider 651, a driving member 652 fixed on the slider 651, and a hammer block 653 driven by the driving member 652 to perform high-frequency reciprocating motion. A slide rail 631 is provided on the upper surface of the second support plate 63, the slider 651 is slidably arranged on the slide rail 631, and a nut sleeve (not shown in the figure) is provided on the slider 651 to cooperate with the screw rod of the servo motor 64. The hammer block 653 moves back and forth in the movable cavity 665.

[0046] In this embodiment, the camera 61 is fixed on the first supporting plate 4 .

[0047] The working principle of a photovoltaic module lead shaping device 100 of the present embodiment is as follows: after the photovoltaic module is delivered to the position through the module conveyor line 1, its position is corrected by the correction module 5; the camera 61 takes a picture of the lead 200 to obtain the lead position, and the Y-axis transfer module 3 automatically adjusts the position of the corresponding lead shaping module 6 according to the obtained lead position information; then the Z-axis transfer module 62 is driven to the working height position, at which time the first inner support block 6622 is very close to the root surface of the lead; the first cylinder 661 and the second cylinder 671 act simultaneously, and the first inner support block 6622 and the second inner support block 6722 are stacked and extend into the two roots. An inner support limit surface 663, left and right limit surfaces 664 and a movable cavity 665 are formed between the leads 200. At this time, the inner sides of the two leads 200 have an inner support limit surface 663 for limit support, and the left and right sides have left and right limit surfaces 664 for limit; so that the position of the lead 200 is accurately positioned; then the servo motor 64 drives the two hammering components 65 to move closer to the working position; the driving member 652 drives the hammer block 653 to reciprocate at a high frequency in the movable cavity 665, frequently impacting and hammering the outer surface of the lead 200, and shaping the lead 200 to a basically vertical state.

[0048] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
