Both ends of the side of the movable plate 209 away from the spring 208 are fixedly connected with a limiting block 210, and the limiting block 210 is slidably connected to the inner wall of the contact plate 204. In the production process of solar cells, the polishing roller is a special tool for polishing the surface of silicon wafers in the production process of solar cells. The main function of the polishing roller is to improve the surface smoothness of the silicon wafers, remove surface defects and irregularities, and thus optimize the photoelectric performance of the solar cell. Generally, the polishing roller body 1 is installed on the mounting rod of the polishing stage of the silicon wafer processing line. When installing the polishing roller body 1, a special installation tool is required. The special tool is used to install the polishing roller body 1 through bolts and screws. The polishing roller body 1 can be installed on the mounting rod by a nut. This installation method is relatively primitive, and the installation steps are cumbersome and the installation speed is slow, which will also affect the work efficiency of polishing the silicon wafer surface by the polishing roller body 1. At this time, the polishing roller body 1 can be installed on the mounting rod by the adjusting device 2, which can increase the speed of installing the polishing roller body 1, so that the polishing roller body 1 can be quickly installed to polish the silicon wafer, which can speed up the production process and improve the production standards.

The handle 37 can increase the speed of opening the limit shell 36.

[0035] The working principle of the polishing roller for solar cell production provided by the present invention is as follows: when the polishing roller body 1 needs to be quickly installed with the mounting rod, the inner wall of the polishing roller body 1 is connected to the mounting rod, and the movable plate 209 can be pressed toward the side close to the fixed plate 207. The movement of the movable plate 209 drives the spring 208 to stretch. At this time, the screw 203 can be rotated by the turntable 217 in the inner wall of the support plate 202. The movement of the screw 203 drives the contact plate 204 to move, and the movement of the contact plate 204 drives the limit rod 206 to move along the angle of the connecting ring 205. Movement, so that the movement of the contact plate 204 can be limited by the limit rod 206, that is, the polishing roller body 1 can be installed on the mounting rod by connecting the two contact plates 204 to the mounting rod, and the movable plate 209 can be loosened at this time, and the spring 208 resets to drive the movable plate 209 to move, so that the limit block 210 installed on the movable plate 209 can be driven by the spring 208 to connect with the inner wall of the contact plate 204, and the limit block 210 can limit the movement of the contact plate 204, so that the angle of rotation of the screw 203 can be fixed by limiting the movement of the contact plate 204.

[0036] When the polishing roller body 1 needs to be stored, the limit shell 36 is rotated. The movement of the limit shell 36 will rotate on the support block 33 through the connecting rod 34. The rotation of the connecting rod 34 will drive the coil spring 35 to stretch. At this time, the unused polishing roller body 1 can be placed on the inner wall of the base plate 31. After placing it, the limit shell 36 can be loosened. The coil spring 35 is reset and will drive the limit shell 36 to move through the connecting rod 34, thereby driving the inner wall of the limit shell 36 to contact the polishing roller body 1, and the storage of the polishing roller body 1 can be completed.
