Figure 8 As shown, this figure shows the structural state diagram of the separation of the support rod 161 and the slide plate 16; when working, when the winding wheel 5 is driven to move in the direction of the other winding wheel 5 by controlling the adjustment mechanism, the slide plate 16 is pushed to move by controlling the telescopic end of the telescopic cylinder 17, and the slide plate 16 drives the support rod 161 and the winding wheel 5 connected thereto to move in the direction of the other winding wheel 5, so that the distance between the two winding wheels 5 can be adjusted. Through this design, it can adapt to photovoltaic welding strips of different lengths, facilitate the detection of different types of photovoltaic welding strips, and is beneficial to the subsequent operation of the photovoltaic welding strips.

[0040] The inner wall of the rectangular groove 15 is provided with two limit grooves 18, and the upper and lower sides of the slide plate 16 are fixedly connected with a clamping rod 162, and the upper and lower clamping rods 162 are respectively slidably connected in the limit grooves 18, and the shape of the clamping rod 162 is adapted to the shape of the limit grooves 18; during operation, when the telescopic end of the telescopic cylinder 17 pushes the slide plate 16 to move, the slide plate 16 will simultaneously drive the upper and lower clamping rods 162 to move, and the upper and lower clamping rods 162 will move in the limit grooves 18. Under the mutual limitation of the clamping rod 162 and the limit grooves 18, the subsequent connecting shaft 13 can facilitate the rotation of the rectangular plate 14 and the winding wheel 5, thereby ensuring the stability of the rectangular plate 14 when driving the support rod 161 and the winding wheel 5 to rotate, and facilitating the detection of the photovoltaic welding strip.

[0041] A shielding frame 19 is provided on one side of the workbench 1, and a shielding plate 20 is slidably connected above the shielding frame 19, and the shielding plate 20 is used to shield the gear 1 3 and the gear 2 4; during operation, when the photovoltaic welding tape is installed, the shielding plate 20 is pulled to shield the top of the workbench 1, and then the entire detection equipment is placed in a safe environment under the shielding of the workbench 1, the shielding frame 19 and the shielding plate 20, so as to avoid the problem that the photovoltaic welding tape will break to the side of the staff when it breaks due to excessive tension during detection.

[0042] An embedding groove 21 is provided above the shielding frame 19, and the shielding plate 20 is slidably connected in the embedding groove 21. A ball is rotatably connected at the connection between the lower end surface of the shielding plate 20 and the inner wall of the embedding groove 21; during operation, when the shielding plate 20 is pushed and pulled, the shielding plate 20 can be pushed into the embedding groove 21, so that the top of the workbench 1 is in a hollow state, so that the photovoltaic welding strip can be installed on the outer peripheral surface of the winding wheel 5 from above.

[0043] The two side walls of the shielding plate 20 are fixedly connected with blocking columns 22, and the blocking columns 22 extend to the outside of the shielding frame 19. The blocking columns 22 are arranged on the outer wall of the shielding plate 20, which can avoid the problem that the shielding plate 20 is completely inside the embedding groove 21 when it is pushed into the embedding groove 21, thereby facilitating the sliding of the shielding plate 20 in the embedding groove 21.

[0044] During operation, when the photovoltaic welding tape is tested, one end of the photovoltaic welding tape is placed on the outer circumference of the winding wheel 5 through the clamping mechanism, and the other end is placed on the outer circumference of the other winding wheel 5 through the clamping mechanism on the other side, and then the motor 2 drives the gear 1 3 to rotate clockwise, and the gear 1 3 drives the gear 2 4 meshing with it to rotate counterclockwise, that is, the rotation directions of the gear 1 3 and the gear 2 4 are opposite, and the gear 1 3 and the gear 2 4 respectively drive the winding wheels 5 connected thereto to rotate, and the two winding wheels 5 rotate in opposite directions, so that the two winding wheels 5 pull the photovoltaic welding tape during the rotation process, so that the photovoltaic welding tape gradually changes from a loose state to a tight state until the photovoltaic welding tape breaks. At this time, the external controller can detect the pressure that the photovoltaic welding tape can withstand during the process of changing from a loose state to a tight state and finally to a broken state, thereby obtaining the tensile strength data of the photovoltaic welding tape, which is convenient for the subsequent use of the photovoltaic welding tape;

[0045] When one end of the photovoltaic welding tape is placed on the outer circumference of the winding wheel 5, the end of the photovoltaic welding tape is placed under the clamping plate 7, and then the telescopic end of the electric push plate 802 at the bottom of the adjustment plate 801 is driven to move, so that the telescopic end of the electric push plate 802 pushes the clamping plate 7 below it, so that the clamping plate 7 rotates and presses on the surface of the photovoltaic welding tape, and the end of the photovoltaic welding tape is fixed, and the fixation of the other end is also the same. Then, through the opposite rotation of gear 1 3 and gear 2 4, the photovoltaic welding tape can be subjected to a tensile operation. Such a design improves the fixing effect and detection efficiency of the photovoltaic welding tape; since a friction pad 9 is provided on the lower end surface of the clamping plate 7, the friction pad 9 will contact the surface of the photovoltaic welding tape, and also improves the friction force of contact with the photovoltaic welding tape, which is convenient for tensile detection;

[0046] If the width of the photovoltaic welding tape is greater than the distance between the limit plate 10 and the side wall of the winding wheel 5, at this time, the telescopic end of the electric pull rod 12 is controlled to drive the limit plate 10 to move, so that the limit plate 10 moves to the side away from the side wall of the winding wheel 5, so that the distance between the limit plate 10 and the side wall of the winding wheel 5 is increased, and then the photovoltaic welding tape can be placed between the limit plate 10 and the side wall of the winding wheel 5. Under the limitation of the limit plate 10, the clamping plate 7 can be conveniently fixed to the end of the photovoltaic welding tape. At the same time, it has a wide adaptability and can detect photovoltaic welding tapes of different widths; if The length of the photovoltaic welding ribbon is short, that is, the two ends of the photovoltaic welding ribbon cannot be pressed by the pressing mechanism. At this time, the winding wheel 5 is driven to move toward the other winding wheel 5 by the control adjustment mechanism, that is, the distance between the two winding wheels 5 is reduced, and then the two ends of the photovoltaic welding ribbon can be pressed by the pressing mechanism on the outer peripheral surface of the winding wheel 5. The gear 1 3 drives the gear 2 4 to rotate, and the gear 2 4 drives the connecting shaft 13 and the rectangular plate 14 to rotate, and the rectangular plate 14 can drive the winding wheel 5 to rotate, so as to perform tensile test on the photovoltaic welding ribbon;

[0047] When the winding wheel 5 is driven to move toward the other winding wheel 5 by controlling the adjustment mechanism, the slide plate 16 is pushed to move by controlling the telescopic end of the telescopic cylinder 17, and the slide plate 16 drives the support rod 161 and the winding wheel 5 connected thereto to move toward the other winding wheel 5, so that the distance between the two winding wheels 5 can be adjusted. Through this design, photovoltaic welding ribbons of different lengths can be adapted, which is convenient for the detection of different types of photovoltaic welding ribbons and is beneficial to the subsequent operation of the photovoltaic welding ribbons;

[0048] When the telescopic end of the telescopic cylinder 17 pushes the slide plate 16 to move, the slide plate 16 will simultaneously drive the upper and lower clamping rods 162 to move, and the upper and lower clamping rods 162 will move in the limiting groove 18. Under the mutual limitation of the clamping rod 162 and the limiting groove 18, it is convenient for the subsequent connecting shaft 13 to drive the rectangular plate 14 and the winding wheel 5 to rotate, ensuring the stability of the rectangular plate 14 when driving the support rod 161 and the winding wheel 5 to rotate, and facilitating the detection of the photovoltaic welding strip; when the photovoltaic welding strip is installed, the shielding plate 20 is pulled to block the top of the workbench 1, and then the workbench 1, the shielding frame 19 and the shielding plate 20 are shielded. The entire detection equipment can be placed in a safe environment to avoid the problem that the photovoltaic welding strip will collapse to one side of the staff when it breaks due to excessive tension during detection;

[0049] When the shielding plate 20 is pushed and pulled, the shielding plate 20 can be pushed into the embedding groove 21, so that the top of the workbench 1 is hollow, so that the photovoltaic welding ribbon can be installed on the outer circumference of the winding wheel 5 from above.
