The clamping mechanism can be flipped 180 degrees to clamp the solar panel to be processed through the clamping mechanism, and then the solar panel is raised by the lifting mechanism and brought into contact with the printing screen 27. After single-sided printing is completed, the solar panel is lowered, and the solar panel is changed by flipping the clamping mechanism. The solar panel is then raised again to the bottom of the screen for printing. After printing is completed, the clamping mechanism is opened and the solar panel can be disassembled for the next process.

[0030] The clamping mechanism is located above the processing table 1 and can clamp both ends of the solar panel. The clamping mechanism includes two arms 2, which are located above the processing table 1 and perpendicular to the upper surface of the processing table 1. The processing table 1 is provided with a movable groove 3 extending along the length direction of the processing table 1. A fixed block 4 is provided at the center of the movable groove 3. A through hole is provided at the center of the fixed block 4, and a first bidirectional screw rod 5 passes through the through hole. Connecting holes are provided at both ends of the processing table 1, and the connecting holes are connected to the movable groove 3.

By rotating the first bidirectional screw rod 5, the two arms 2 can be controlled to move in opposite directions at the same time, thereby adjusting the spacing between the arms 2.

[0031] In order to make the clamping mechanism flippable, it is convenient for double-sided printing on the solar panel, the clamping mechanism also includes two rotating plates 7, and the two arms 2 are provided with movable openings 8 extending in the vertical direction, and a horizontally placed connecting rod 9 is provided in the movable opening 8. The rotating plate 7 is located between the two arms 2 and is parallel to the arms 2. The two rotating plates 7 are respectively fixedly connected to the two connecting rods 9, and the other ends of the connecting rods 9 are fixedly connected to a stopper 10, and the stopper 10 is fixedly connected to a rotating rod. The other end of the rotating rod is fixedly connected to the handle, and rotating the handle can rotate the rotating plates 7 together; a support is provided on one side of the rotating plates 7 close to each other. A support plate 11 is provided, the support plate 11 is perpendicular to the rotating plate 7 and is fixedly connected to the rotating plate 7.

[0032] To limit the tilting angle of the clamping mechanism, a stopper 15 is provided on the side of the two arms 2 that face away from each other. Two stoppers 15 are provided, one on either side of the stopper 10 and positioned on the same horizontal plane. A stopper rod 16 is fixedly attached to the stopper 10 and positioned above the stopper 15. Rotating the handle causes the stopper rod 16 on the stopper 10 to rotate with it. The combination of the stopper rod 16 and the stopper 15 allows the solar panel to rotate a maximum of 180°.

[0033] During the printing process, since the solar panel is too long, fixing only the two ends may easily cause the solar panel to break during the printing process, so a support mechanism is also provided above the processing table 1; a groove perpendicular to the movable groove 3 is provided on the processing table 1, the groove is located above the movable groove 3, and the groove extends along the width direction of the processing table 1 to the edge of the processing table 1, and the support mechanism is located in the groove.

One of the fixed plates 18 is provided with a through hole connected to the slide groove, and a short rod is also provided in the through hole. The short rod is fixedly connected to the second bidirectional screw rod 19 and the knob respectively; a slider 21 is provided on the second bidirectional screw rod 19, and a threaded hole is provided on the slider 21. The second bidirectional screw rod 19 passes through the threaded hole on the slider 21, and the slide An L-shaped support block 22 is provided above the block 21. The two support blocks 22 are placed opposite to each other, and an intermediate support rod can be connected between the two support blocks 22. The intermediate support rod can penetrate the two support blocks 22 at the same time. The intermediate support rod can also be a telescopic rod with a telescopic structure. By rotating the second bidirectional screw 19, the support blocks 22 can be moved in opposite directions at the same time to adapt to solar panels of different widths; at the same time, in order to make the support mechanism move up and down, an electric telescopic rod 23 is provided under the lifting plate 17. The electric telescopic rod 23 is located in a groove on the processing table 1, and the movable end of the electric telescopic rod 23 is fixedly connected to the lower surface of the lifting plate 17. When the electric telescopic rod 23 pushes the lifting plate 17 to move vertically, the lifting plate 17 can support the middle part of the solar panel to be printed.

[0034] A screen frame 24 is also provided above the processing table 1. The screen frame 24 is connected to the processing table 1 through a positioning column 25. The two ends of the positioning column 25 are fixedly connected to the upper surface of the processing table 1 and the lower surface of the screen frame 24 respectively. The screen frame 24 is a circular structure. Guide rods 26 are provided on the inner side of the length side of the screen frame 24. There are four guide rods 26, with two guide rods 26 on each side. A printing screen 27 is connected between the guide rods 26. When the support mechanism lifts the solar panel to the lower end of the printing screen 27, the solar panel can be printed by the printing equipment.

[0035] During operation, first place the solar panel to be processed on the processing table 1, adjust the second bidirectional screw 19 to fix the solar panel, and lift the solar panel to the clamping mechanism through the electric telescopic rod 23. Adjust the spacing of the support arms 2 through the first bidirectional screw 5 to make it the same as the length of the solar panel. Fix the solar panel on the clamping mechanism by tightening the threaded rod 13, and lift the solar panel to the bottom of the printing screen 27 through the electric telescopic rod 23 again. After the printing device finishes printing, the solar panel descends. Due to the restriction of the movable opening 8, the solar panel is now located at the center of the support arm 2. Turn the handle to flip the solar panel 180°, and lift the solar panel to the bottom of the printing screen 27 through the support mechanism again. After printing is completed, the support mechanism returns to its original position, the locking mechanism is opened, and the solar panel is removed to proceed to the next step.
