Description

Technical Field

[0001] This utility model relates to the field of solar cell stacked grid back grid string welding technology, specifically to a handling device with a leveling function. Background Technology

[0002] In the stringing process of single-sided stacked grid photovoltaic cells, multiple solder strips are welded onto the cell. These solder strips are welded to the busbar to form a cell unit, and then multiple cell units are connected in series to form a cell string.

[0003] In the soldering process, hot glue is used to fix the solder wires. However, the hot glue has a shrinkage property after curing, which will create non-uniform shrinkage stress on the solar cells, causing additional warping deformation. Due to the internal stress remaining during the manufacturing process, the busbar is prone to natural curling. When using traditional solar cell handling devices for transfer, their gripping method cannot adapt to the warped state of the solar cells and the curled state of the busbar. This can easily cause misalignment of the stacked solar cells, offset of the soldering strip, or bending of the busbar. As a result, the key indicators such as dimensional accuracy and fit of the stacking process do not meet the quality requirements of the stringing process. Utility Model Content

[0004] In view of this, the present invention provides a handling device with a leveling function for leveling the busbar when handling battery strings.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A handling device with a leveling function includes a pressure strip assembly, a support assembly, and a lifting plate assembly;

[0007] The pressure strip assembly and the cell lifting assembly are spaced apart on the support assembly; the cell lifting assembly can attract and press the cell; the pressure strip assembly can press the busbar.

[0008] Furthermore, there are multiple pressure strip assemblies and multiple lifting sheet assemblies, which are distributed alternately along the length of the support assembly.

[0009] Furthermore, the pressure strip assembly includes a lifting drive and a pressure strip. The lifting drive is mounted on the bracket assembly, and the pressure strip is connected to the drive end of the lifting drive. The lifting drive is used to drive the pressure strip to move up and down.

[0010] Furthermore, the pressure strip has multiple raised parts on its flat surface.

[0011] Furthermore, the bracket assembly includes a mounting base and a flange, with the flange located at one end of the mounting base, and the pressure strip assembly and the lifting plate assembly spaced apart at the other end of the mounting base.

[0012] Furthermore, the lifting assembly includes a suction cup base, multiple suction cups and a pressing component. The suction cup base is connected to the bracket assembly. The bottom of the suction cup base is provided with multiple suction cups and a pressing component, with the multiple suction cups arranged around the pressing component.

[0013] Furthermore, it also includes a robotic arm, with the support assembly connected to the drive end of the robotic arm.

[0014] Furthermore, the pressing component is elastically connected to the bottom of the suction cup base.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] By using an alternating arrangement of the pressure strip assembly and the lifting assembly, while the lifting assembly adsorbs the solar cells, the pressure strip assembly can apply targeted pressure to the busbar on the solar cells. The suction cup and pressing component of the lifting assembly form a collaborative structure. When the suction cup adsorbs the solar cells under negative pressure, the pressing component and the suction cup adsorption port simultaneously adhere to the surface of the solar cells. Mechanical limiting eliminates the curling of the solar cells themselves, ensuring that the busbar is flat and avoiding the positional displacement or damage caused by uneven solar cells during the traditional adsorption process.

Detailed Implementation

[0024] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] It should be noted that when a component is said to be "set on" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] like Figures 1 to 5 As shown, this application discloses a handling device with a leveling function, including a pressure strip assembly 100, a support assembly 200, and a lifting plate assembly 300;

[0028] Specifically, the pressure strip assembly 100 and the lifting assembly 300 are spaced apart on the bracket assembly 200; the lifting assembly 300 can adsorb and press the battery cell; the pressure strip assembly 100 can press the busbar.

[0029] During the use of the handling device, the device moves above the battery cells and their busbars. The cell lifting assembly 300 contacts and adsorbs the battery cells through vacuuming. Upon contact, the adsorption combined with mechanical limiting presses the battery cells. Simultaneously, the pressure strip assembly 100, corresponding to the busbar position, releases pressure on the busbar upon contact, performing a pressing operation. After leveling is completed simultaneously, the device lifts the battery cells and their busbars and moves them to the target position, releases the battery cells and their busbars and resets them, completing the battery cell stacking process.

[0030] In the above structure, the spaced arrangement of the pressure strip assembly 100 and the lifting assembly 300 enables the synchronous operation of cell handling and busbar leveling, which greatly improves production efficiency.

[0031] In this embodiment, there are multiple pressure strip components 100 and multiple lifting plate components 300, and the multiple pressure strip components 100 and multiple lifting plate components 300 are distributed alternately along the length direction of the support component 200.

[0032] Specifically, in this embodiment, two sets of pressure strip assemblies 100 and two sets of lifting assemblies 300 are preferably set, with the spacing adapted to the distribution spacing of the busbars on the battery string, ensuring that each set of pressure strip assemblies 100 can accurately correspond to one busbar. During the operation, two sets of battery cells and their busbars can be extracted and transported at the same time, which can adapt to the processing requirements of multi-busbar battery strings, and meet diversified production needs by increasing or decreasing the number of components.

[0033] In this embodiment of the application, the pressure strip assembly 100 includes a lifting drive 101 and a pressure strip 102. The lifting drive 101 is disposed on the bracket assembly 200, and the pressure strip 102 is connected to the driving end of the lifting drive 101. The lifting drive 101 is used to drive the pressure strip 102 to move up and down.

[0034] Specifically, the lifting drive component 101 can be a cylinder or a motor, and this application does not impose any restrictions on it.

[0035] In this embodiment, the pressing surface of the pressing strip 102 is provided with multiple protrusions.

[0036] In the above structure, the lifting drive 101 drives the pressure strip 102 to descend and contact the busbar, applying pressure to the busbar. The raised part increases the friction with the busbar, ensuring that the pressing process does not slip. After completion, the lifting drive 101 drives the pressure strip 102 to rise and reset. The lifting drive 101 realizes the lifting of the pressure strip. With the design of the raised part, it not only ensures the flattening effect of the busbar, but also enhances the stability of the operation process. The detachable pressure strip assembly can be adjusted in time to be compatible with different sizes of busbars.

[0037] In this embodiment, the bracket assembly 200 includes a mounting base 201 and a flange 202. The flange 202 is disposed at one end of the mounting base 201, and the pressure strip assembly 100 and the lifting plate assembly 300 are spaced apart at the other end of the mounting base 201.

[0038] In this embodiment, the lifting assembly 300 includes a suction cup base 301, a plurality of suction cups 302 and a pressing member 305. The suction cup base 301 is connected to the bracket assembly 200. The bottom of the suction cup base 301 is provided with a plurality of suction cups 302 and a pressing member 305, and the plurality of suction cups 302 are arranged around the pressing member 305.

[0039] Specifically, the suction cup base 301 has an adapter 304 at its top center, which connects to an external pneumatic component. The pressing component 305 includes multiple support rods 303. The pressing component 305 has openings that correspond one-to-one with the suction cups 302, and the suction port of the suction cups 302 extends from the openings of the pressing component 305. The support rods 303 are cylindrical and shorter than the length of the suction cups 302. The end away from the suction cup base 301 has an external thread. The pressing component 305 has a mounting hole at the corresponding position. After the support rods 303 pass through the mounting holes, they are locked and fixed by nuts. The external pneumatic component provides negative pressure through the adapter 304. The suction cups 302 contact the battery cells and generate suction force. The pressing component 305 adheres to the surface of the battery cells under atmospheric pressure and achieves leveling by limiting the movement of the limit and moving synchronously with the suction cup.

[0040] In the above structure, the synergistic effect of multiple suction cups 302 and pressing element 305 is used to level the battery cells while adsorbing them, thereby improving work efficiency.

[0041] In this embodiment, a robotic arm 400 is also included. The support assembly 200 is connected to the drive end of the robotic arm 400, and its execution end is provided with a docking flange. The edge of the docking flange is provided with an elastic buckle corresponding to the slot of the connecting flange 202. The elastic buckle engages and is fixed with the slot. The robotic arm 400 is used to drive the pressure strip assembly 100 and the lifting plate assembly 300 to move in a three-dimensional direction.

[0042] Specifically, the robotic arm 400 drives the entire device to move precisely in three-dimensional space. The quick-locking structure of the elastic buckle facilitates the rapid assembly and disassembly of the device and the robotic arm, meeting the needs of rapid changeover on the production line and realizing the flexible movement and precise positioning of the device.

[0043] In this embodiment, the pressing member 305 is elastically connected to the bottom of the suction cup base 301.

[0044] Specifically, the pressing component 305 is elastically connected to the bottom of the suction cup base 301 via a compression spring. The bottom of the suction cup base 301 has a pre-set groove or mounting post. One end of the compression spring is sleeved or fixed in the mounting post, and the other end is fixed to the inner end face of the pressing component 305. When pressing, a flexible pressing effect is achieved, avoiding the pressing component 305 from directly and rigidly impacting the surface of the battery cell.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model.
