[0002] For photovoltaic power generation equipment, battery cells are an important component. In the production process of photovoltaic modules, multiple battery cells need to be welded in series to form a battery string, and multiple groups of battery strings need to be connected through bus bars to form a battery array, which involves the layout of the battery strings.

[0003] In the prior art, conveyor belts and robotic arms are usually used to handle the steps of battery string layout operations, and the battery string layout process is fully automated to effectively improve the layout efficiency. However, the existing robotic arms are relatively large in size, so they require a certain amount of floor space. In order to increase production, factories now advocate the reduction of equipment size, so there is an urgent need for a smaller battery cell handling arm. At the same time, due to design defects or jitters in the handling of existing robotic arms, there is also the problem of unstable handling of battery strings and bus bars.

DETAILED DESCRIPTION

[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0036] See attached Figures 1 to 4 As shown, a handling hand that can be used in the processing of solar photovoltaic panels includes a swing arm base plate 25, a first rotation drive mechanism 26, a rotating arm 27, a secondary arm 28, a balance arm 29 and a horizontal fixing seat 31. The horizontal fixing seat 31 can be used to fix an adsorption component 32 for adsorbing a battery string 4 (see Figure 7 ), can also be used to fix the horizontal transfer platform 2 loaded with the prepared busbar 1 (see Figure 8 ).

[0037] like Figure 7 , 8 As shown, the swing arm base plate 25 can be fixed on the slider 20 of a linear driving module 23, so as to realize the overall translation of the transport arm.

[0038] The first end of the rotating arm 27 is hinged on the swing arm bottom plate 25. The first rotation driving mechanism 26 is positioned on the swing arm bottom plate 25, and drives the rotating arm 27 to rotate with its first end as the rotation point. The first end of the auxiliary arm 28 is hinged on the swing arm bottom plate 25, and is arranged adjacent to the first end of the rotating arm 27. The line connecting the two hinge points is defined as the first line L1, and the first line L1 has an angle α with the horizontal plane.

[0039] The second end of the auxiliary arm 28 is hinged to the first end of the balance arm 29, and the second end of the balance arm 29 is hinged to the second end of the rotating arm 27. The line connecting the two hinge points is defined as the second line L2, and the second line L2 is parallel to the first line L1.

[0040] The connecting end of the horizontal fixing seat 31 is rotated to pass through the second end of the rotating arm 27 and is fixedly connected to the second end of the balancing arm 29; the bottom end of the horizontal fixing seat 31 is fixedly provided with the adsorption component 32 for adsorbing the battery string 4, and the adsorption action surface of the adsorption component 32 is parallel to the horizontal plane.

[0041] In order to ensure the stability of product transportation, the bottom surface of the adsorption component 32 needs to be always parallel to the horizontal plane, so the first connecting line L1, the rotating arm 27, the auxiliary arm 28, and the balance arm 29 (the second connecting line L2) are designed as a parallelogram. Therefore, when the first rotating drive mechanism 26 drives the rotating arm 27 to rotate, the angle α between the first connecting line L1 and the horizontal plane can remain unchanged, and the angle α between the second connecting line L2 and the horizontal plane also remains unchanged. Therefore, the adsorption action surface of the adsorption component 32 fixed relative to the balance arm 29 and the parallel state of the horizontal plane also remain unchanged.

[0042] Preferably, an elastic member is further included, which acts between the balancing arm 29 and the rotating arm 27, so that when the rotating arm 27 rotates, a reverse damping force is generated through the elastic member. With this design, when the rotating arm 27 rotates to the target position, it can quickly stabilize to avoid unnecessary shaking, thereby facilitating the smooth transportation of the battery string 4 on the adsorption assembly 32.

[0043] Preferably, the elastic member is a tension spring 35 , a spring shaft 34 is disposed on the balance arm 29 , a spring shaft 34 is also disposed on the rotating arm 27 , and the tension spring 35 is connected between the two spring shafts 34 .

[0044] Preferably, a bearing 30 is further included, and a notch 33 is provided at the front of the second end of the rotating arm 27 , and the bearing 30 is placed in the notch 33 .

[0045] like Figure 5 , Figure 6 As shown, it is another solution of this embodiment, the bottom end of the horizontal fixing seat 31 is fixed with the adsorption component 32 for adsorbing the battery string 4 through a rotating bottom plate 36 .

[0046] The handling arm also includes a second rotation drive mechanism 39, which is fixed on the horizontal fixed seat 31, and its rotation axis is arranged along the z-axis and is fixedly connected to the rotating base plate 36, and is used to drive the rotating base plate 36 to rotate around the z-axis (such as 90° rotation). With this design, the handling arm can rotate the battery string 4 while translating the battery string 4, and can rotate the battery string 4 parallel to the x-axis direction to be parallel to the y-axis direction, so as to meet the position arrangement requirements of the battery string 4 in subsequent processing steps.

[0047] like Figure 8As shown, the platform surface of the horizontal transfer platform 2 is provided with multiple groups of clamping claw cylinders 3 for clamping the busbar 1 at intervals along its length direction. The horizontal transfer platform 2 is directly driven to rise and fall by the carrier, and is indirectly translated by the carrier sliding on the linear drive module 23.

[0048] In order to ensure the stability of transporting the busbar 1, the platform surface of the horizontal transfer platform 2 needs to be always parallel to the horizontal plane. Through the parallelogram design, the parallel state between the platform surface of the horizontal transfer platform 2 and the horizontal plane can be kept unchanged.

[0049] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
