[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0020] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a photovoltaic cell bending strength testing device, including a base frame 1. A pressing mechanism 2 is fixedly installed on the base frame 1. The pressing mechanism 2 includes a top frame 21, an electric push rod 22, and a pressing block 23. The top frame 21 is fixedly installed on the top surface of the base frame 1, the electric push rod 22 is fixedly installed on the top surface of the top frame 21, and the pressing block 23 is fixedly installed on the extended end of the electric push rod 22. The electric push rod 22 facilitates the movement of the pressing block 23. When the pressing block 23 moves down, it presses the battery, thereby causing the battery to bend, so as to detect the bending strength of the battery.

[0021] The top surface of the pressure block 23 is symmetrically provided with two vertical plates 24, which are movably inserted into the top frame 21. When the pressure block 23 moves, the two vertical plates 24 cooperate to increase the stability of the pressure block 23 during movement.

[0022] A control rod 3 is installed inside the base frame 1. The control rod 3 includes a rotating rod 31 and a motor 32. The two ends of the rotating rod 31 are rotatably inserted into two sliding grooves 13. The motor 32 is fixedly installed on the side wall of the base frame 1. The rotating shaft of the motor 32 is fixedly connected to one end of the rotating rod 31. The outer walls of both ends of the rotating rod 31 are provided with threaded grooves, and the thread directions of the two external threads are opposite. Two cams 33 are symmetrically fitted on the outer wall of the rotating rod 31. The cams 33 are in the movable cavity 12. The motor 32 can drive the rotating rod 31 to rotate. The two external threads cooperate with the two clamping parts 4 so that the rotating rod 31 can control the movement of the clamping parts 4. The two clamping parts 4 move in opposite directions, so that the two clamping parts 4 cooperate to facilitate the clamping and release of the battery.

[0023] Two clamping parts 4 are symmetrically arranged on the control lever 3. Two jet nozzles 5 are symmetrically inserted into the front side of the base frame 1. Two piston parts 6 are symmetrically arranged inside the base frame 1. The piston parts 6 slide against the outer wall of the control lever 3. The top surface of the base frame 1 has a groove 11 corresponding to the pressure block 23. Two movable cavities 12 are symmetrically opened inside the base frame 1. The two piston parts 6 are respectively installed in the two movable cavities 12. The top surface of the base frame 1 has two sliding grooves 13 symmetrically opened. The two clamping parts 4 are respectively movably arranged in the two sliding grooves 13. The groove 11 allows the battery to bend downwards. The movable cavity 12 facilitates the installation of the piston parts 6. The sliding groove 13 facilitates the installation of the clamping parts 4.

[0024] The clamping component 4 includes a movable plate 41 and a side plate 42. The lower end of the movable plate 41 is inserted into the slide groove 13 and threaded onto the rotating rod 31. The upper end of the movable plate 41 extends out of the slide groove 13 and is fixedly connected to the side plate 42. The side wall of the side plate 42 has two limiting grooves 43. Two limiting blocks 44 are movably arranged in the two limiting grooves 43. The limiting blocks 44 are connected to the inner bottom wall of the limiting groove 43 by a first spring 45. A rubber plate 46 is fixedly arranged at one end of the limiting block 44 that extends out of the limiting groove 43. A horizontal plate 47 is movably inserted into the side wall of the side plate 42. A steel cable 48 is fixedly arranged on the bottom surface of the limiting block 44. The lower end of the steel cable 48 passes through the limiting groove 43 and is fixedly connected to the top surface of the horizontal plate 47.

[0025] When the rotating rod 31 rotates, it causes the movable plate 41 to slide along the inner wall of the slide groove 13. At this time, the movable plate 41 drives the side plate 42 to move towards the battery. When the horizontal plate 47 comes into contact with the battery, the horizontal plate 47 moves and pulls the steel cable 48 to move. At this time, the steel cable 48 pulls the limiting block 44 and the rubber plate 46 to move downward, thereby pressing the battery through the rubber plate 46 to increase the stability of the side plate 42 when clamping the battery. When the side plate 42 separates from the battery, the first spring 45 pushes the limiting block 44 and the rubber plate 46 to move upward. At this time, the limiting block 44 pulls the steel cable 48 to move, and the steel cable 48 pulls the side plate 42 to reset.

[0026] The piston component 6 includes a piston plate 61 and an abutment rod 62. The piston plate 61 is movably disposed in the movable cavity 12, and the top surface of the piston plate 61 is connected to the inner top wall of the movable cavity 12 through a second spring 63. The abutment rod 62 is fixedly disposed on the bottom surface of the piston plate 61 and slides with the outer wall of the cam 33. The second spring 63 facilitates pushing the piston plate 61 and the abutment rod 62 downward, thereby ensuring that the abutment rod 62 is always in contact with the outer wall of the cam 33. The rotating rod 31 facilitates driving the cam 33 to rotate. As the cam 33 rotates, it is easy to control the abutment rod 62 and the piston plate 61 to move up and down reciprocatingly, thereby continuously pushing the airflow in the movable cavity 12 into the jet nozzle 5.

[0027] The air inlet of the nozzle 5 is connected to the inner wall of the active cavity 12, and the air outlet of the nozzle 5 is bent toward the groove 11. When the nozzle 5 sprays air, it is convenient to blow away the debris in the groove 11 to reduce the debris remaining in the groove 11.

[0028] Working principle: When using this photovoltaic cell bending strength testing device, the cell is first placed on the base frame 1. Then, the clamping part 4 is moved by the control rod 3 to clamp and fix the cell. Then, the cell is bent by the pressing mechanism 2. In conjunction with other existing testing equipment, the bending strength of the cell is tested. After the cell test is completed, the clamping part 4 is reset by the control rod 3. At the same time, the piston part 6 is moved by the control rod 3, thereby pushing the airflow in the base frame 1 into the jet nozzle 5. Then, the airflow is sprayed through the jet nozzle 5 to blow away the debris on the surface of the base frame 1.

[0029] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
