Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3The utility model provides an embodiment: a kind of tension testing device for solar backsheet film, comprising: workbench 1, the surface of workbench 1 is symmetrically provided with moving groove 101, and tension assembly 2 is arranged between two moving grooves 101, by the setting of tension assembly 2, when two clamping components 4 are opposite to move to solar backsheet film tension test, after solar backsheet film is pulled apart, simultaneously stop rotating screw rod 201, at this time, two threaded sleeves 202 stop moving, and the degree on tensile force sensor 3 is observed, so that the tension data of solar backsheet film can be more accurately measured, and the middle position of the top of workbench 1 is fixedly installed with tensile force sensor 3, and the output end of tensile force sensor 3 is fixedly connected with pull rope 301, one end of pull rope 301 is fixedly installed on the surface of one side of tension assembly 2, and clamping component 4 is arranged on the both sides of the top of tensile force sensor 3. By the setting of clamping component 4, the clamping effect of solar backsheet film can be improved, solar backsheet film is avoided to fall off at both ends in tension test, and test data is influenced, and it is convenient to operate.

[0021] Please refer to Figure 1-2 In the embodiment of the utility model: tension assembly 2 includes: screw rod 201, screw rod 201 is rotationally installed between two moving grooves 101 in horizontal direction, both ends of screw rod 201 are rotationally installed with the inside of workbench 1, one end of screw rod 201 extends to the outside of one side of workbench 1, screw cap is fixedly connected at the end of one end of screw rod 201, so as to facilitate the rotation of screw rod 201, screw rod 201 is symmetrically screw-mounted with threaded sleeve 202 on the surface, and threaded sleeve 202 is slidingly installed on the inner wall of adjacent moving groove 101 on the surface, and clamping component 4 is arranged on the top of threaded sleeve 202. After the fixation of both ends of solar backsheet film is completed by two clamping components 4, by rotating U-shaped frame 401, at this time, two clamping components 4 are opposite to move to solar backsheet film tension test, after solar backsheet film is pulled apart, simultaneously stop rotating screw rod 201, at this time, two threaded sleeves 202 stop moving, and the degree on tensile force sensor 3 is observed, so that the tension data of solar backsheet film can be more accurately measured, and it is worth integrating that, before solar backsheet film tension, after the fixation of both ends of solar backsheet film, by the opposite movement of two fixed plates 402, solar backsheet film is stretched to flat state, simultaneously, pull rope 301 and solar backsheet film are in horizontal state, avoid not being tensioned when testing, and solar backsheet film and pull rope 301 are wrinkled, affect the accuracy of test result.

[0022] Please refer to Figure 1-2In this embodiment of the present invention, screw rod 201 is threaded on both its left and right ends, with the threads running in opposite directions. Because the threads on screw rod 201 run in opposite directions, when screw rod 201 is rotated, the threaded sleeves 202, symmetrically threaded on the surface of screw rod 201, can move simultaneously relative to or in opposite directions, thereby performing tension testing on the solar backsheet film.

[0023] See also Figure 1-3 , in an embodiment of the present utility model: the clamping assembly 4 includes: a U-shaped frame 401, the U-shaped frame 401 is fixedly installed on the top of the adjacent threaded sleeve 202, one side of the U-shaped frame 401 is fixedly connected to a fixed plate 402, and both ends of the fixed plate 402 are horizontally movable and penetrated with movable rods 403, one end of the two movable rods 403 is fixedly connected with a splint 404, the middle part of the splint 404 is provided with a waist-shaped cavity 405, the other end of the two movable rods 403 is fixedly connected with a connecting plate 406, and the middle position of the connecting plate 406 is horizontally threaded with a threaded rod 407, and one end of the threaded rod 407 is rotatably installed inside one side of the fixed plate 402. When the two ends of the solar backsheet film are clamped, one end of the solar backsheet film is passed through the waist-shaped cavity 405 in the direction close to the fixed plate 402, and then passed upward from the gap between the clamping plate 404 and the fixed plate 402. In this way, after one end of the solar backsheet film is wrapped around the clamping plate 404 for 2 to 3 turns, the threaded rod 407 is rotated. At this time, the connecting plate 406 threadedly installed on the surface of the threaded rod 407 moves in the direction away from the fixed plate 402 under the guidance of the movable rod 403, thereby driving the clamping plate 404 to approach the surface of the fixed plate 402. After the movable rod 403 drives the clamping plate 404 to move into place, the rubber protrusion on the upper end of one side of the clamping plate 404 squeezes and clamps one end of the wound solar backsheet film between the fixed plate 402 and the clamping plate 404 to fix one end of the solar backsheet film. In this way, the clamping effect of the solar backsheet film can be improved, and the two ends of the solar backsheet film can be prevented from falling off during the tension test, affecting the test data.

[0024] See also Figure 1-3 In this embodiment of the present invention, a plurality of rubber protrusions are evenly spaced in an array on the upper end of the clamping plate 404, near the fixed plate 402. When the connecting plate 406 pulls the two symmetrical movable rods 403 on one side of the clamping plate 404 outward into position, the rubber protrusions on the upper end of the clamping plate 404 press the solar backsheet film tightly against the surface of the fixed plate 402. The rubber protrusions increase friction between the solar backsheet film and the rubber protrusions, thereby improving the stability of the solar backsheet film at the end of the clamping plate 404.

[0025] See also Figure 2-3In the embodiment of the present invention, a bearing is provided on the surface of one end of the threaded rod 407, with the inner ring of the bearing fixedly connected to the surface of the threaded rod 407, and the outer ring of the bearing fixedly connected to the interior of the fixed plate 402. The bearing arrangement allows one end of the threaded rod 407 to rotate freely within the fixed plate 402.

[0026] Working principle: Turn on the power supply, and in the tension test of the solar backsheet film, insert one end of the solar backsheet film through the waist-shaped cavity 405 in the direction close to the fixed plate 402, and then pass it upward from the gap between the clamping plate 404 and the fixed plate 402. In this way, after wrapping one end of the solar backsheet film around the clamping plate 404 for 2 to 3 turns, rotate the threaded rod 407. At this time, the connecting plate 406 threadedly installed on the surface of the threaded rod 407 moves away from the fixed plate 402 under the guidance of the movable rod 403, thereby driving the clamping plate 404 to approach the surface of the fixed plate 402. After the clamping plate 404 is moved into position, the rubber protrusion on the upper end of the clamping plate 404 is used to squeeze and clamp one end of the wrapped solar backsheet film between the fixing plate 402 and the clamping plate 404 to fix one end of the solar backsheet film. After the two ends are fixed, the U-shaped frame 401 is rotated, and the two clamping assemblies 4 move in opposite directions to test the tension of the solar backsheet film. After the solar backsheet film is broken, the rotation of the screw rod 201 is stopped at the same time, and the two threaded sleeves 202 stop moving. By observing the degree on the tension sensor 3, the tension data of the solar backsheet film can be measured more accurately. The content not described in detail in this specification belongs to the existing technology known to professionals in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
