Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0019] Such as figure 2 As shown: the cells after laser scribing are placed on the suction cup 26, and there is a joint 25 on the suction cup 26, and the joint 25 is connected to a negative pressure device to suck the cells. 31 turns.

[0020] Such as image 3 As shown: the motor 31 is fixed on the motor fixing plate support 33 through the motor fixing plate 32, the rotation of the motor 31 drives the rotation of the cam 37 installed on the motor, the position sensor stopper 36 is housed on the cam 37, and the position sensor 35 passes through the sensor fixing plate 34 is fixed on the motor fixed plate 32, and after the position sensor 35 confirms that the motor 31 rotates to the lobe position, the motor 31 stops. The cam 37 lifts the guide rod 13 through the c...

Abstract

The invention relates to a device and a method for automatically cleaving battery pieces, and belongs to the technical field of solar battery pieces. The device for automatically cleaving battery pieces mainly comprises a support, a vacuum adsorption assembly and a cleaving assembly. The vacuum adsorption assembly comprises two sucking discs, each sucking disc is provided with a plurality of vacuum adsorption holes for sucking a battery piece, and the sucking discs are connected with air pressure sensors and drive a motor of the cleaving assembly to rotate after receiving signals; a position sensor is arranged on the cleaving assembly; when receiving sensors signals on the sucking discs, the cleaving assembly controls a drive motor to drive a cam to move; and the cam rolls opposite to a bearing follower in the vacuum adsorption assembly, so that a guide rod connected with the bearing follower moves up to jack the middle position of the two sucking discs in the vacuum adsorption assembly to realize cleaving. The device and the method can be used for automatically cleaving battery pieces after laser scribing, are high in efficiency with respect to manual cleaving, good in section uniformity and low in breaking rate, and can be applied to battery pieces with different size and different type.

Description

technical field [0001] The invention relates to an automatic cell splitting device and method, belonging to the technical field of solar cells. Background technique [0002] At present, in the production of solar cells, when the conversion efficiency of the cells is constant, the method of cutting the cells in half horizontally and then connecting them in series is often used to increase the power generation power of the modules. There are two processes for cutting the cell in half. One is to use laser to scribe the middle of the cell horizontally. The width and depth of the scribing line need to be precisely controlled. At present, the common splitting is manual splitting or using a manual splitting mechanism, or the control of the designed cell splitting is integrated with the control system of the entire device. Modularization has not been realized, the control cost is relatively high, and debugging is difficult. Contents of the invention [0003] The technical problem...
