Description

Technical Field

[0001] The utility model relates to the technical field of welding strip production, in particular to a photovoltaic welding strip coating thickness gauge. Background Art

[0002] Solder ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the solder ribbon will directly affect the current collection efficiency of the photovoltaic module and have a greater impact on the power of the photovoltaic module. The solder ribbon is coated with a solder coating. The uniformity of the solder coating will affect the cost of solder ribbon production and the strength effect of solder ribbon use. Therefore, in the process of producing solder ribbon, it is necessary to sample and detect whether the thickness of the coating on the solder ribbon is uniform and consistent and maintained within the specified range. When the thickness of the coating is found to be abnormal, the production equipment of the solder ribbon should be adjusted in time to avoid the problem of large batches of products with non-compliant coating thickness being scrapped.

[0003] In the prior art, the coating is generally tested by a special welding ribbon coating thickness measuring device. For example, a thickness measuring device for photovoltaic welding ribbon coating with publication number CN115014261 B detects the thickness of the coating by contacting the photovoltaic welding ribbon coating with a thickness measuring instrument.

[0004] Existing thickness gauges, such as a coating thickness gauge with publication number CN208936955U, include a body, a probe, and a wire connecting the body and the probe. The body includes a housing, and a wire winding hook for receiving the wire is provided on the housing. The wire winding hook of this thickness gauge can wind and arrange the wire, but cannot fix the wire. When the probe of the gauge is unfixed by external impact, the wire will be unwound during the falling process, so that the wire is in disarray and needs to be rearranged. Summary of the invention

A reinforcement ring 4 is arranged at the connection between the detection head 2 and the wire 3, and the radius of the reinforcement ring 4 is smaller than the radius of the detection head 2.

[0031] A winding structure 5 is provided on the back of the body 1, and an upper hook body 51 of the winding structure 5 is slidably provided on the back of the body 1. A gap is left between the top of the upper hook body 51 and the back of the body 1, and one end of the upper hook body 51 is slidably connected in the body 1; a lower hook body 52 is slidably provided on the back of the body 1, and a gap is left between the bottom of the lower hook body 52 and the back of the body 1. A return spring 53 is provided at one end of the upper hook body 51 and the lower hook body 52 and inside the body 1. A vertical rod 54 is fixedly provided between the upper hook body 51 and the lower hook body 52. ​​A horizontal connecting rod 55 is fixedly provided on the surface of the vertical rod 54. A rotating rod 56 is rotatably provided inside the connecting rod 55, and one end of the rotating rod 56 close to the vertical rod 54 extends out from the connecting rod 55, and a pinch block 57 is provided on the side where the rotating rod 56 extends out. A sliding rod 58 is coaxially arranged at one end of the rotating rod 56 away from the pinch block 57. The radius of the sliding rod 58 is the same as that of the connecting rod 55. Blocks 59 are arranged on both sides of one end of the sliding rod 58. The connecting rod 55 is arranged vertically between the back of the machine body 1. A sliding groove 510 is arranged on the back of the machine body 1. One end of the connecting rod 55 extends into the inside of the sliding groove 510. Limiting grooves 511 are arranged on both sides of the sliding groove 510. The position and shape of the limiting groove 511 are adapted to the block 59. A fixing groove 512 is arranged at the bottom end of the limiting groove 511. The diameter of the fixing groove 512 is larger than the diameter of the limiting groove 511. The diameter of the fixing groove 512 is equal to the distance between the limiting grooves 511 on both sides. A connecting plate 6 is arranged on the back of the machine body 1. The connecting plate 6 is located above the winding structure 5. A clamping groove 7 is opened on the surface of the connecting plate 6. The shape of the clamping groove 7 is adapted to the reinforcing ring 4. A connecting block 8 is disposed on the top surface of the connecting plate 6 , and a setting groove 9 is provided at the center of the connecting block 8 . The shape of the setting groove 9 is adapted to the shape of the probe.

[0032] When using this photovoltaic welding strip coating thickness gauge, take out the probe and align it with the photovoltaic welding strip coating to be tested, then start the thickness gauge through the control panel to test the coating, and the detection data of the probe is fed back to the electric control device in the housing 11 through the wire 3, and then fed back to the display screen 12, so as to detect the specified photovoltaic welding strip coating thickness. After the detection is completed, the wire 3 of the probe is wound and arranged on the winding structure 5. At this time, the upper hook body 51 and the lower hook body 52 are pushed out from the inside of the body 1 by the force of the reset spring 53. The gap between the upper hook body 51 and the lower hook body 52 to the body 1 is large, so that the wire 3 can be directly wound and arranged between the upper hook body 51 and the lower hook body 52 through the gap. Then the probe is clamped in the setting groove 9, and the reinforcement ring 4 is set in the clamping groove 7. Then, by pinching the pinching block 57, the connecting rod 55, the upper hook body 51 and the lower hook body 52 are driven to approach the inside of the body 1. At this time, the restoring spring is compressed, and the connecting rod 55 and the rotating rod 56 extend into the sliding groove 510. The blocks 59 at both ends of the sliding rod 58 slide in the limiting groove 511. When the blocks 59 of the sliding rod 58 slide into the fixing groove 512, the pinching block 57 is rotated, and the pinching block 57 synchronously drives the rotating rod 56 and the sliding rod 58 to rotate, so that the blocks 59 and the limiting groove 511 are misaligned, so that the sliding rod 58 and the connecting rod 55 are fixed in the sliding groove 510, and the gap between the upper hook body 51, the lower hook body 52 and the machine body 1 is reduced, so that the wound wire 3 cannot be taken out from the surface, and the wire 3 is fixed between the upper hook body 51 and the lower hook body 52. ​​When it is necessary to take out the wire 3, by rotating the pinching block 57 to the position of the limiting groove 511, the upper hook body 51 and the lower hook body 52 are automatically ejected by the force of the reset spring 53, so that the gap between the hook body and the machine body 1 becomes larger, and the wire 3 can be directly taken out from the surface of the upper hook body 51 and the lower hook body 52.

[0033] Working principle of the utility model: A photovoltaic welding strip coating thickness gauge of the utility model is provided with a winding structure 5, and the wire 3 can be wound between the upper hook body 51 and the lower hook body 52 of the winding structure 5, so that the wire 3 can be arranged between the upper hook body 51 and the lower hook body 52, and the connecting rod 55 can drive the upper hook body 51 and the lower hook body 52 to extend into the body 1, thereby reducing the gap between the hook body and the body 1, and fixing the wire 3 wound inside; by providing a rotating rod 56, after the rotating rod 56 drives the sliding rod 58 to extend into the fixing groove 512, the rotating rod 56 drives the sliding rod 58 to rotate, and the blocks 59 on both sides of the sliding rod 58 are misaligned with the limit groove 511, thereby fixing the sliding rod 58 and the connecting rod 55, and indirectly fixing the upper hook body 51 and the lower hook body 52, and positioning the wound wire 3.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
