Description

Technical Field

[0001] The utility model relates to the technical field of solar cell assembly production, in particular to a string lifting device. Background Art

[0002] Before the battery strings are welded to the busbars, multiple battery strings are arranged on the glass plate. The arranged battery strings flow into the busbar welding equipment along with the glass plate. After the battery strings are lifted and corrected by the battery string lifting device, the busbars are welded to the battery strings using a welding head.

[0003] In the prior art, when calibrating a battery string, the battery string lifting device calibrates the battery string from three aspects: first, rotating the battery string to adjust the angle of the battery string; second, moving the battery string in the X direction to adjust the distance between each two adjacent battery strings; third, moving the battery string in the Y direction to align the ends of all battery strings. The rotation of the battery string is achieved through two cam mechanisms. However, the angle adjustment range of the cam mechanism is limited. When the adjustment angle is too large, it is difficult for the cam mechanism to adjust it to the preset position. In addition, the cam mechanism has a complex structure and is prone to jamming.

DETAILED DESCRIPTION

[0020] The technical solution and technical effects of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features directly contacting, and can also include the first and second features not directly contacting but contacting through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0022] In the description of this embodiment, the terms "upper", "lower", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0023] like Figure 1-Figure 4As shown, the utility model provides a string lifting device for lifting and correcting a battery string, which includes a lifting mechanism 10 and a crossbeam 11, the lifting mechanism 10 and the crossbeam 11 are driven and connected to make the crossbeam 11 move up and down, a plurality of first longitudinal plates 12 are slidably connected at the bottom of the crossbeam 11, a second longitudinal plate 13 is slidably connected at the bottom of each first longitudinal plate 12, the first longitudinal plate 12 can move relative to the crossbeam 11 in a first direction, the second longitudinal plate 13 can move relative to the first longitudinal plate 12 in a second direction, the first direction and the second direction are perpendicular; a bottom plate 14 is provided below each second longitudinal plate 13, the bottom plate 14 is rotatably connected to the second longitudinal plate 13, a third motor 17 is provided on the second longitudinal plate 13, a meshing member 131 is provided on the bottom plate 14, a driving gear of the third motor 17 is meshed with the meshing member 131, and a plurality of first suction cups 18 are provided on the bottom plate 14. The meshing member 131 can be a gear or an arc-shaped rack.

[0024] In the present invention, the first direction is the length direction of the crossbeam 11, and the second direction is the length direction of the first longitudinal plate 12, the second longitudinal plate 13 and the bottom plate 14; the lifting mechanism 10 is preferably an electric cylinder. Before correcting the battery string, the lifting device can use a camera mechanism to confirm the position of each battery string, calculate the deviation between the current position of each battery string and the preset position, and correct the battery string according to the deviation. When correcting the battery string, after the first suction cup 18 adsorbs the battery string, the lifting mechanism 10 is used to lift the multiple battery strings, and the first suction cup 18 on each bottom plate 14 adsorbs the same battery string. After the battery string is lifted, the battery string is corrected from three aspects at the same time: first, the first motor 15 is used to drive the first longitudinal plate 12 to move along the first direction to adjust the spacing between the multiple battery strings; second, the second motor 16 is used to drive the second longitudinal plate 13 to move along the second direction to align the ends of the multiple battery strings; third, the third motor 17 is used to drive the bottom plate 14 to rotate to adjust the multiple battery strings parallel to the second direction. If the edges of two battery strings overlap, the first motor 15 is used to separate the two battery strings, and then the battery strings are corrected from three aspects at the same time. In the utility model, each of the first motor 15, the second motor 16, and the third motor 17 is independently controlled, and the gear meshing structure is used to adjust the angle of the battery string within a large range.

[0025] In an optional embodiment, one end of the second longitudinal plate 13 is rotatably connected to the bottom plate 14 via a bearing, and the third motor 17 is disposed at the other end of the second longitudinal plate 13. Preferably, the engagement member 131 is an arc-shaped rack. The third motor 17 and the rotation center are located at both ends of the second longitudinal plate 13, so as to maximize the transmission ratio and increase the angle adjustment accuracy of the battery string.

[0026] In an optional embodiment, a limiting assembly 19 is provided in the middle section of the second longitudinal plate 13, and the limiting assembly 19 includes a first limiting member 191 and a second limiting member 192 respectively extending to both sides of the bottom plate 14. The first limiting member 191 and the second limiting member 192 can limit the angular range of rotation of the bottom plate 14 and prevent the driving gear of the third motor 17 from disengaging from the meshing member 131.

[0027] In an optional embodiment, the bottom plate 14 includes a third longitudinal plate 141 and a fourth longitudinal plate 142 stacked up and down, the two ends of the third longitudinal plate 141 are fixedly connected to the fourth longitudinal plate 142, and there is a gap between the middle section of the third longitudinal plate 141 and the fourth longitudinal plate 142. One of the first limiting member 191 or the second limiting member 192 is an L-shaped plate, and the horizontal part of the L-shaped plate extends into the gap. There is a very small distance between the horizontal part and the third longitudinal plate 141, for example, 0-0.5mm. On the one hand, it prevents the L-shaped plate and the third longitudinal plate 141 from rubbing against each other, and on the other hand, it prevents the bottom plate 14 from shaking too much. When the bottom plate 14 and the second longitudinal plate 13 are assembled, their center of gravity is located between the third motor 17 and the rotation center of the bottom plate 14. When the lifting mechanism 10 drives the cross beam 11 to move up and down, the bottom plate 14 will swing up and down due to inertia, increasing the load at the connection between the second longitudinal plate 13 and the bottom plate 14. The bottom plate 14 will contact the L-shaped plate during the up and down swinging process, and the L-shaped plate can prevent the bottom plate 14 from swinging up and down.

[0028] In an optional embodiment, each first longitudinal plate 12 is provided with a first motor 15 and a second motor 16, the first motor 15 is connected to the cross beam 11 for driving so that the first longitudinal plate 12 moves in the first direction, and the second motor 16 is connected to the second longitudinal plate 13 for driving so that the second longitudinal plate 13 moves in the second direction. Along the first direction, a linear rack 111 is provided on the cross beam 11, and the driving gear of the first motor 15 is meshed with the linear rack 111. Multiple first motors 15 share the same linear rack 111, and the spacing between adjacent battery strings is adjusted by the cooperation between the first motor 15 and the linear rack 111.

[0029] In an optional embodiment, a fifth longitudinal plate 20 is further provided between any two adjacent bottom plates 14. A row of second suction cups 21 are provided on the fifth longitudinal plate 20 along the second direction. The fifth longitudinal plate 20 is slidably connected to an adapter plate 22, which is connected to the bottom of the crossbeam 11. A fourth motor 23 is provided on the adapter plate 22. The fourth motor 23 is driven and connected to the fifth longitudinal plate 20 to make the fifth longitudinal plate 20 move up and down. The second suction cups 21 are used to absorb the busbar. In some solar cell modules, there is a busbar parallel to the length direction of the battery string. Before the lifting device advances the battery string, the busbar is laid on the battery string. Before the lifting mechanism 10 cooperates with the first suction cup 18 to advance the battery string, the fourth motor 23 and the second suction cup 21 first cooperate to lift the busbar to separate the busbar from the battery string, and then calibrate the battery string.

[0030] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
