[0027] See also Figure 1 As shown, the present invention provides a technical solution: a photovoltaic welding strip tensile strength testing device, comprising a base plate 101, supporting legs are fixedly installed at the four corners of the lower surface of the base plate 101, a central slide plate 102 is fixedly installed in the middle of the base plate 101, a drawer plate 106 is slidably installed on the central slide plate 102, storage boxes 104 are symmetrically arranged on both sides of the drawer plate 106 for storing welding strips 117 to be tested, two storage boxes 104 are fixedly installed on the base plate 101 through a C-shaped frame 103, a reset spring rod bracket 105 is fixedly installed at one end of the drawer plate 106 away from the C-shaped frame 103, a reset spring rod 107 is movably installed between the reset spring rod bracket 105 and the C-shaped frame 103, it should be noted that the storage box 104 is slidably connected to the drawer plate 106, and the function of the reset spring rod 107 is that when the drawer plate 106 slides relative to the storage box 104, the reset spring rod 107 will be compressed, thereby resetting the drawer plate 106.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig. 9As shown, detection modules are symmetrically arranged on both sides of the central slide 102, and the detection modules include two first clamping frames 112 and two second clamping frames 113 on the same horizontal plane as the drawer board 106. The detection module also includes two welding strip support sheets 118, and the two welding strip support sheets 118 are respectively fixedly installed on one of the first clamping frames 112 and one of the second clamping frames 113, so that one end of the welding strip support sheet 118 will overlap with the other first clamping frame 112 and the other second clamping frame 113, and the two first clamping frames 112 and the second clamping frames 113 are fixedly installed with a safety frame 115, and after the safety frame 115 is installed 5, the first clamping frame 112 and the second clamping frame 113 are both fixedly installed with a tensile support slide bar 116, the tensile support slide bar 116 is slidably connected with another first clamping frame 112 and another second clamping frame 113, and the end of the tensile support slide bar 116 away from the insurance frame 115 is fixedly installed with a tensile spring 121 for testing the tensile strength of the welding strip 117, so the tensile spring 121 is fixedly connected with the first clamping frame 112 and the second clamping frame 113 slidably installed on the tensile support slide bar 116, and a material stripping assembly is arranged on the side of the insurance frame 115, and the material stripping assembly includes a T-shaped frame fixedly installed on the central slide plate 102 122, a stripping plate 124 is slidably mounted on the T-shaped frame 122, and a vertical spring rod 123 is movably mounted on the top of the stripping plate 124 and the T-shaped frame 122, which is used to reset the stripping plate 124, and a convex block is fixedly mounted on the lower surface of the stripping plate 124 at a position corresponding to the solder strip support sheet 118, which is used to push the solder strip 117 down on the solder strip support sheet 118, and the fallen solder strip 117 will fall into the III groove opened on the bottom plate 101, and then fall into the collection box 128 to collect the detected solder strip 117, and a threaded slider 110 is slidably mounted on one of the first clamping frames 112 through a sliding plate 111, and a screw slider 110 is fixed on the bottom plate 101 A motor 108 is installed, and a lead screw 109 is fixedly installed on the output shaft of the motor 108. The lead screw 109 is threadedly matched with the threaded slider 110 to drive the sliding plate 111 and the first clamping frame 112 to move horizontally. It should be noted that one end of the sliding plate 111 is slidingly connected to the threaded slider 110, and the other end of the sliding plate 111 is fixedly connected to the first clamping frame 112, and both ends of the lead screw 109 are rotatably installed on the base plate 101, wherein the lead screw 109 is symmetrically arranged on both sides of the central slide 102 and is transmitted through the transmission belt 129. Therefore, when the motor 108 rotates, it will drive the lead screws 109 on both sides to rotate together.

[0029] like Figure 7 and Figure 8As shown, a clamping assembly is provided on each of the two first clamping frames 112 for fixing the welding strip 117, a transverse spring rod 114 is movably installed between the first clamping frame 112 and the second clamping frame 113, and the clamping assembly includes a clamping arm 127 rotatably installed on the first clamping frame 112, a clamping bar 125 is meshed with a gear at the bottom end of the clamping arm 127, a gear is provided at the bottom end of the clamping arm 127, a rack is correspondingly provided on the upper surface of the clamping bar 125, one end of the clamping bar 125 is fixedly connected to the second clamping frame 113, the other end of the clamping bar 125 is slidably connected to the first clamping frame 112 via a clamping bar slider 126, and a spring is fixedly installed between one end of the clamping bar 125 close to the second clamping frame 113 and the clamping bar slider 126.

[0030] like Fig.10 , Fig.11 , Fig.12 , Fig.13As shown, two slide grooves Ⅰ and Ⅱ are respectively opened on the bottom plate 101 at both sides of the central slide plate 102, and the limiting columns 120 are slidably installed in the two slide grooves, one of which is fixedly connected to the first clamping frame 112 slidably connected to the stretching support slide bar 116, and the other is fixedly connected to the sliding plate 111. When the two first clamping frames 112 move along the two slide grooves Ⅰ and Ⅱ under the restriction of the limiting columns 120, the transverse spring rod 114 will be compressed or extended. Because the two slide grooves Ⅰ and Ⅱ are offset in the radial direction of the horizontal plane of the stretching support slide bar 116, the limiting column 120 will also be offset. When the transverse spring rod 111 4 is compressed, it means that the first clamping frame 112 and the second clamping frame 113 are close to each other. At this time, the clamping arm 127 will press the welding strip 117 placed on the welding strip supporting plate 118 under the restriction of the clamping strip 125, so as to fix the welding strip 117. A limit plate 119 is arranged at the end of the I slide groove. When the first clamping frame 112 slidably connected with the stretching support slide bar 116 touches the limit plate 119, the first clamping frame 112 here cannot continue to move forward, but the sliding plate 111 slidably connected with the threaded slider 110 will continue to move forward, because the sliding plate 111 is only fixedly connected with the other first clamping frame 112. At this time, the tension spring 121 will be compressed, and the distance between the two first clamping frames 112 and the two second clamping frames 113 will become larger. Because the two ends of the welding ribbon 117 have been fixed on the two first clamping frames 112 and the second clamping frames 113, the welding ribbon 117 will be subjected to tension at this time. When the first clamping frame 112 is compressed to a predetermined variable, if the welding ribbon 117 does not break, it means that the welding ribbon 117 is qualified, and vice versa. When it is necessary to take down the welding ribbon 117 after the inspection on the welding ribbon support sheet 118, it is necessary to rotate the motor 108 in the reverse direction to let the second clamping frame 113 slide in the reverse direction on the central slide plate 102. Here, It is explained that all the second clamping frames 113 are slidably installed on the side of the central slide 102, so the welding strip 117 will also move with it. When the welding strip 117 moves to contact with the cam on the stripping plate 124, the second clamping frame 113 will continue to move. When the protrusion completely pushes the welding strip 117 off the welding strip supporting piece 118, it will continue to move forward. At this time, the safety frame 115 will lift the stripping plate 124 and compress the vertical spring rod 123. The vertical spring rod 123 here plays the role of resetting the stripping plate 124. The purpose here is to prevent the protrusion on the stripping plate 124 from blocking the welding strip 117 when the welding strip 117 to be tested is loaded.

[0031] When loading, let the second clamping frame 113 abut against the drawer plate 106. Fig.13As shown, the drawer plate 106 is pushed back to overcome the elastic force of the reset spring rod 107. It should be noted that the elastic force of the tension spring 121 should be greater than the elastic force of the reset spring rod 107. When the two first clamping frames 112 and the second clamping frames 113 are moved to the lower surface of the storage box 104, the welding strip 117 to be tested placed inside the storage box 104 will fall onto the welding strip support sheet 118, and then exit, and continue to test the new welding strip 117. Repeat the above steps to perform multiple tests.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
