The three-axis movable module comprises an x-axis movable module 2 disposed at the top of the column 1, a y-axis movable module 3 connected to the x-axis movable module 2, and a z-axis movable module 4 connected to the y-axis movable module 3.

[0025] like Figure 2 As shown, the x-axis moving module 2 includes an x-axis fixed frame 21 fixed to the top of the column 1, a top plate 22 is fixed to the top of the x-axis fixed frame 21, and an x-axis sliding frame 23 is sleeved on the top plate 22.

[0029] like Figure 5 As shown, the clip mechanism 5 includes a mounting seat 51 disposed on the z-axis moving module 4, and the mounting seat 51 is connected to the symmetrical clamping assembly through a telescopic sliding clamping structure. A lifting vertical plate 48 is disposed at the top of the z-axis sliding frame 47, and the lifting vertical plate 48 is connected to the mounting seat 51 through a triangular fixing frame 2 49.

[0030] The telescopic sliding clamping structure includes a telescopic cylinder 52 arranged on a mounting seat 51, and the cylinder rod of the telescopic cylinder 52 penetrates the mounting seat 51 and is connected to a fixed seat 55 through a connecting structure, and the fixed seat 55 is connected to a symmetrical clamping assembly through a sliding structure. The connecting structure includes a connecting seat 53, and both ends of the connecting seat 53 are hinged with connecting rods 54, and the bottom end of the connecting rod 54 is hinged to the fixed seat 55. The bottom end of the mounting seat 51 is connected to a sliding plate 58 through a fixing rod 59. The sliding structure includes a sliding seat 56, and the fixing seat 55 is fixedly arranged at the top of the sliding seat 56. The bottom end of the sliding seat 56 is slidably connected to the sliding plate 58 through a slide rail 57.

[0031] The symmetrical clamping assembly includes a symmetrically arranged clamping plate 510, the top of which is fixedly connected to the sliding seat 56. A clamping claw 511 is arranged on the inner side of the clamping plate 510, and a drag claw 512 is arranged at the bottom of the clamping claw 511. The photovoltaic cell group 6 includes a plurality of stacked photovoltaic cells, and a clamping plate 1 61 and a clamping plate 2 62 are arranged at the top and bottom of the stacked photovoltaic cells, respectively, and the drag claw 512 is located at the bottom of the clamping plate 2 62.

[0032] When in use, first place the second clamp 62 on the ground, then stack multiple photovoltaic cells on the second clamp 62, and place the first clamp 61 on the top to form a photovoltaic cell group 6; the motor 25 drives the x-axis sliding frame 23 to move through the reducer and the screw 24, and then drives the entire clamp mechanism 5 to move along the x-axis, the y-axis cylinder 34 drives the y-axis sliding frame 33 to move, and then drives the entire clamp mechanism 5 to move along the y-axis, and the rodless cylinder 45 drives the mounting seat 51 to move up and down, and then drives the entire clamp mechanism 5 to move along the z-axis, so as to realize accurate and rapid three-axis movement and adjustment of the clamp mechanism 5, so that the clamp mechanism 5 is located directly above the photovoltaic cell group 6.

[0033] The telescopic cylinder 52 drives the connection seat 53 to descend, and then drives the connection rod 54 to rotate. The connection rod 54 rotates to push the fixed seat 55 outward. The fixed seat 55 moves to drive the sliding seat 56 to move outward on the slide rail 57, so that the symmetrically arranged clamping plate 510 moves outward. The entire clamping mechanism 5 then moves along the z-axis. The telescopic cylinder 52 drives the connection seat 53 to rise, and then drives the clamping plate 510 to move inward through multiple structures, so that the clamping claw 511 clamps the photovoltaic cell group 6 and grabs the photovoltaic cell group 6. When grabbing, the drag claw 512 is located at the bottom end of the second clamping plate 62, and the entire photovoltaic cell group 6 is dragged to improve the stability of the grabbing. After grabbing the photovoltaic cell group 6, the photovoltaic cell group 6 is moved to the target position through the z-axis moving module 4, the y-axis moving module 3, and the x-axis moving module 2.

[0034] Therefore, the present invention adopts a three-axis movable clamping mechanism of the above structure, which can solve the problems of low grasping efficiency and easy damage to photovoltaic cells in the process of grasping cells by existing photovoltaic cell grasping mechanisms, thereby affecting product quality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
