[0021] like Figure 1-Figure 7 As shown, the utility model is a fixing device for detecting solar cells, comprising a detection platform 1 and a fixing mechanism 2 arranged on the detection platform 1, and also comprising a conveyor 3 for automatically transmitting the solar cells, the conveyor 3 being arranged on the detection platform 1, the fixing mechanism 2 comprising two symmetrically arranged groups of moving plates 5 and a spacing adjustment component 7, the detection platform 1 is provided with a slide rail 4, the moving plates 5 are slidably arranged on the slide rail 4, the spacing adjustment component 7 is arranged on the detection platform 1, and is used to adjust the distance between the two groups of moving plates 5, and each group of moving plates 5 is symmetrically provided with two groups of fixing components 6 for fixing the solar cells; the spacing adjustment component 7 comprises a connecting rod 13, a first motor 14 and a rotating arm 15, the first motor 14 is arranged on the detection platform 1, the rotating arm 15 is arranged on the output shaft of the first motor 14, the connecting rod 13 is hinged on the rotating arm 15, the connecting rod 13 is provided with two groups, the two groups of connecting rods 13 are arranged in parallel, and the two groups of moving plates 5 are hinged on the two groups of connecting rods 13 respectively.

[0022] The fixing assembly 6 includes a rotating shaft 8, an L-shaped plate 9, a torsion spring 10, a positioning roller 11 and a slider 12. The slider 12 is arranged on the movable plate 5. The rotating shaft 8 is rotatably arranged on the slider 12. The L-shaped plate 9 is arranged on the rotating shaft 8. The torsion spring 10 is sleeved on the rotating shaft 8. The two ends of the torsion spring 10 are respectively arranged on the L-shaped plate 9 and the slider 12. The positioning roller 11 is rotatably arranged on the L-shaped plate 9. There are two groups of positioning rollers 11, and the two groups of positioning rollers 11 can respectively contact the two adjacent side surfaces of the solar cell; a slide groove 16 is provided on the movable plate 5, and a bidirectional threaded rod 17 is rotatably arranged in the slide groove 16. The slider 12 is sleeved on the bidirectional threaded rod 17 by a thread and is slidably arranged in the slide groove 16; a second motor 18 is provided on the movable plate 5, and one end of the bidirectional threaded rod 17 is arranged on the output shaft of the second motor 18.

[0023] In the initial state, the axis line of the two groups of positioning rollers 11 on the same group of L-shaped plates 9 is parallel to the material conveying direction of the conveyor 3. When in use, the distance between the two groups of movable plates 5 is first adjusted according to the size of the solar cell. When adjusting, it is only necessary to start the first motor 14 to make the first motor 14 drive the rotating arm 15 to rotate, and the rotating arm 15 drives the two groups of movable plates 5 to move closer to or away from each other through the two groups of connecting rods 13, thereby achieving the adjustment of the distance between the two groups of movable plates 5, and then the solar cell is placed on the conveyor 3, and the conveyor 3 can automatically convey the solar cell. After the solar cell is conveyed to the specified position, the conveyor 3 stops running, and the second motor 18 is started to make the second motor 18 drive the bidirectional threaded rod 17 to rotate, and the bidirectional threaded rod 17 drives the two groups of sliders 12 thereon to move closer to each other, so that the four groups of fixed components 6 are respectively close to the four corners of the solar cell. As the slider 12 drives the L-shaped plate 9 toward the solar cell, one of the groups of positioning rollers 11 on the L-shaped plate 9 first contacts one side of the solar cell. Then, as the slider 12 continues to move, the L-shaped plate 9 rotates at a certain angle, and the torsion spring 10 is twisted, so that another group of positioning rollers 11 on the L-shaped plate 9 contacts the other side of the solar cell. Thus, one corner of the solar cell can be restricted by two positioning rollers 11 on a group of L-shaped plates 9, and the four corners of the solar cell can be restricted respectively by four groups of fixing components 6, thereby achieving the fixation of the solar cell, which can well meet the fixation requirements of solar cells of different sizes. After the detection is completed, the second motor 18 is driven to rotate in the direction, so that the four groups of fixing components 6 are synchronously moved away from the solar cell product, and the torsion spring 10 is restored. Then, the solar cell can be automatically transported to the next processing station through the conveyor 3.

[0024] In summary, the present solution is provided with a fixing mechanism 2, which can drive the two groups of movable plates 5 to move closer to or away from each other through the first motor 14, and can drive the two groups of sliders 12 on each group of movable plates 5 to move closer to or away from each other through the second motor 18, thereby meeting the fixing requirements for solar cells of different sizes and having higher practicality; the present solution is provided with a conveyor 3, which can automatically transport the solar cells through the conveyor 3, thus saving more manpower.
