[0026] Please refer to Figures 1 to 6A solar cell cutting mechanism includes a first base plate 1, a second base plate 2, a turntable 3, and a cutting assembly 4. The turntable 3 is rotatably mounted on the first base plate 1 and has at least two gripping assemblies 5 for fixing and picking up solar cells a. These gripping assemblies 5 are spaced circumferentially along the axis of rotation of the turntable 3 relative to the first base plate 1. The cutting assembly 4 is adjustablely mounted on the second base plate 2 and includes an upper cutter 43 and a lower cutter 44. The space between the upper cutter 43 and the lower cutter 44 is located on the path of the solar cell a on the gripping assembly 5, which rotates synchronously with the turntable 3. In this embodiment, by using at least two gripping assemblies 5 to transport the solar cell a to be cut to the cutting assembly 4 via the rotation of the turntable 3, the processing efficiency can be improved. The adjustable cutting assembly 4, mounted on the second base plate 2, can adaptively adjust its position according to the posture of the incoming solar cell a, i.e., the part b1 to be cut, to ensure processing accuracy. In this embodiment, optionally, there are four gripping components 5 and two cutting components 4 arranged adjacent to each other. One cutting component 4 is used to cut the part b1 to be cut near the center of the turntable 3, and the other cutting component 4 is used to cut the part b1 to be cut away from the center of the turntable 3, so as to improve processing efficiency. Figure 3 As shown, the turntable 3 is rotatably mounted on the first base plate 1 via a DD motor 11, which drives the turntable 3 to rotate 90° in a single rotation. In this embodiment, the cutting assembly 4 is adjustablely mounted on the second base plate 2 via an electric displacement stage 21. In use, the solar cell a is first photographed using a CCD camera (not shown) to determine its orientation. Then, the spatial position of the cutting assembly 4 is adjusted using the electric displacement stage 21 to adapt to the orientation of the solar cell a, thereby achieving high-precision cutting.

[0027] like Figure 4 As shown, the gripping component 5 includes a gripping plate 51, which is mounted on the turntable 3. The gripping plate 51 has an adsorption surface 510 with a plurality of adsorption holes 511. In this embodiment, the solar cell a is attached to the adsorption surface 510 and fixed by negative pressure adsorption, facilitating the loading and unloading of the solar cell a.

[0028] In some embodiments, the gripping plate 51 is provided with a plurality of weight reduction holes 512.

[0029] like Figure 4 and Figure 5As shown, the turntable 3 includes a central portion 31, which is rotatably mounted on the first base plate 1. At least two extension frames 32 are arranged around the central portion 31, and the gripping assembly 5 is mounted on the extension frame 32. Each extension frame 32 includes at least one radial rod 321, on which a tangential rod 322 is mounted. The extension frame 32 formed by the combination of the radial rod 321 and the tangential rod 322 is grid-like, lightweight, and high-strength. In some embodiments, to further improve the strength of the extension frame 32, a reinforcing rod 320 is mounted between two adjacent tangential rods 322. In this embodiment, the gripping plate 51 is connected to at least one of the radial rod 321, the tangential rod 322, and the reinforcing rod 320 by bolts or screws.

[0030] like Figure 6 As shown, the cutting assembly 4 also includes a blade holder 41, on which two drive units 42 are configured to drive the upper blade 43 and the lower blade 44 respectively. Each drive unit 42 includes a base plate frame 421 and a blade holder 422. The base plate frame 421 is disposed on the blade holder 41, and the blade holder 422 is equipped with a guide shaft 4221 extending longitudinally. The blade holder 422 is used to assemble the upper blade 43 and the lower blade 44. The guide shaft 4221 passes through the base plate frame 421 and is slidably connected to it. A drive member 4222 is disposed on the base plate frame 421 to drive the blade holder 422 to move longitudinally. In this embodiment, optionally, the drive member 4222 is a cylinder. In use, the cylinder drives the upper blade 43 and the lower blade 44 to move longitudinally to cooperate in cutting the part to be cut b1, i.e., the conductive wire b.

[0031] Furthermore, the tool holder 41 includes a base plate 411, on which two side plates 412 are spaced apart, and several connecting plates 413 are connected between the two side plates 412. The base plate frame 421 is assembled onto the connecting plates 413. This tool holder 41 has a simple and stable structure, is lightweight, and is easy to adjust in attitude via the electric displacement stage 21.

[0032] like Figure 6 As shown, the side plate 412 includes a main body 4121 extending longitudinally. A first extension 4122 is provided at the upper end of the main body 4121, and a second extension 4123 is provided at the lower end of the main body 4121. Both the first extension 4122 and the second extension 4123 extend horizontally and toward the turntable 3. The first extension 4122 and the second extension 4123 are used to assemble the drive unit 42. In this embodiment, the drive unit 42 is mounted on the first extension 4122 and the second extension 4123 via a connecting plate 413, so that there is sufficient space between the upper cutter 43 and the lower cutter 44 to accommodate the turntable 3.
