[0002] Photovoltaic welding ribbon is also called tinned copper ribbon or tin-coated copper ribbon. It is divided into collector ribbon and interconnection ribbon. It is used to connect the solar cells of photovoltaic modules and plays an important role in conducting electricity. The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of photovoltaic modules and has a great impact on the power of photovoltaic modules.

[0003] In the process of producing welding strips, it is necessary to sample and test whether the thickness of the welding strips is uniform and consistent and maintained within the specified range.

The two side rods 51 respectively penetrate the two limit blocks 53 and are slidably connected with the two limit blocks 53. When the first transverse screw rod 49 rotates, the two pushing blocks 50 are driven to move in the opposite direction, thereby driving the two side rods 51 and the side plates 52 to move in the opposite direction. The opposite ends of the side rods 51 are fixedly connected with the side plates 52, and the tops of the two side plates 52 are fixedly connected with mounting plates 56.

[0026] When the present scheme is in use, the welding tape to be tested is rolled up on the hanging rod, one end of the photovoltaic welding tape on the winding roller is pulled out, and the front end of the photovoltaic welding tape is passed through between the two rear clamps 27, and then extended into between the two front clamps 34, and then the driving motor 35 is started to drive the second bidirectional screw rod 32 to rotate, and the second bidirectional screw rod 32 drives the two third sliders 33 to move in the opposite direction during rotation, and then the two second bidirectional screw rods 32 drive the two front clamps 34 to move relative to each other and clamp the front end of the welding tape, and then the first motor is started to drive the first bidirectional screw rod 2 to rotate, and the first bidirectional screw rod 2 drives the first moving block 3 and the second moving block 36 to move to both sides respectively, so as to stretch the welding tape and make the welding tape roll on the hanging rod, and the welding tape stops stretching after being stretched to the required length, so as to facilitate the adjustment of the length of the welding tape detection.

[0027] In addition, the second slider 22 and the first slider 18 are made of different materials. The second slider 22 is heavier to balance the two sides. The cylinder 6 is started to drive the connecting block 7 and the bracket 8 to descend, so that the bracket 8 drives the two rotating shafts 9 to follow and descend. When the two rotating shafts 9 descend, they drive the two sprockets 10 to descend, and at the same time drive the first guide gear 12 and the second guide gear 13 to descend. When the first guide gear 12 and the second guide gear 13 descend, the first guide gear 12 and the second guide gear 13 will simultaneously drive the first guide rack 14 and the second guide rack 15 to move downward, so that the first The guide rack 14 and the second guide rack 15 slide inside the first sliding sleeve 4 at the same time. When the first guide rack 14 and the second guide rack 15 descend at the same time, they drive the two connecting plates 16 to descend, so that the two connecting plates 16 drive the first transmission rack 19 and the second transmission rack 23 to descend. When the first transmission rack 19 descends, it drives the first slider 18 fixedly connected thereto to descend. At the same time, the first transmission rack 19 is meshed and connected with the first transmission gear 21. When the first transmission gear 21 rotates, it drives another meshed first transmission rack 19 to rise, and then the two first transmission racks 19 respectively drive the two first sliders 18 moves relative to each other, and drives the two rear clamping plates 27 to move relative to each other, so that the two rear clamping plates 27 clamp and fix the rear end of the welding strip, which is convenient for detecting the welding strip. Since the distance between the two rear clamping plates 27 is smaller than the distance between the two cutter heads 28, the two rear clamping plates 27 first contact with the welding strip to fix the welding strip. When the two rear clamping plates 27 are fixed to the welding strip, they cannot move further. At this time, the cylinder 6 is still driving the bracket 8 to descend, so the first transmission rack 19 and the second guide rack 15 no longer move. At the same time, the bracket 8 drives the second guide gear 13 to descend when it descends, and the second guide gear 13 is meshed and connected with the second guide rack 15, which will make The second guide gear 13 rotates clockwise when descending, thereby driving the first guide gear 12 to rotate clockwise through the chain 11 and the sprocket 10, and the first guide gear 12 drives the first guide rack 14 to continue to descend, so that the first guide rack 14 drives the second transmission rack 23 to descend, and then the two second sliders 22 are driven by the second transmission gear 24 to move relative to each other, so that the two cutter heads 28 move relative to each other, and the welding strip behind the fixed end is cut off. The fixing and cutting of the welding strip are implemented simultaneously, which is convenient for operation and detection. There is no need for manual cutting, which improves work efficiency, reduces material loss, and is convenient for subsequent use.

[0028] The forward and reverse motor 44 is started to drive the driving shaft 45 to rotate, and drives the rotating sleeve 40 to rotate. When the rotating sleeve 40 rotates, the guide strips 42 on both sides of the interior thereof limit the guide grooves 43, thereby driving the threaded rod 41 to rotate synchronously. Because the threaded rod 41 is threadedly connected to the support plate 38, when the threaded rod 41 rotates, it rises, so that the threaded rod 41 drives the cross plate 46 to rise, and at the same time, the cross plate 46 drives the elastic plate 57 to rise. At the same time, when the threaded rod 41 rotates, it drives the first bevel gear 47 to rotate and drives The two second bevel gears 55 rotate, and then the second bevel gears 55 drive the two first transverse screw rods 49 to rotate, so that the first transverse screw rod 49 drives the two push blocks 50 to move in the opposite direction, and drives the two mounting plates 56 away from each other, so that the elastic plate 57 gradually flattens, and when the elastic plate 57 rises, it contacts the bottom of the welding strip, and by controlling the spacing between the first moving block 3 and the second moving block 36, the welding strip gradually fits tightly with the surface of the elastic plate 57, which is beneficial to support the welding strip, make the welding strip taut, and facilitate the detection of the thickness of the welding strip surface.

[0029] The thickness gauge 65 is driven down by the electric push rod 64 to move the thickness gauge 65 to contact the welding strip, so that the thickness gauge 65 detects the thickness of the surface of the welding strip. Since the welding strip is kept in a straight state, the detection result is more accurate, and the problem of inaccurate detection value caused by bending of the welding strip will not occur. The second motor is started to drive the second transverse screw rod 61 to rotate, and the second transverse screw rod 61 drives the third moving block 60 to move, thereby driving the fixed plate 37 and the upper cover plate 59 to move, so as to adjust the thickness of different areas on the cut welding strip, which is conducive to comparing the detection data and improving the accuracy of the detection.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
