[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon, branch current ribbon and interconnection strip, is used to connect photovoltaic modules and cells. 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 the photovoltaic module and has a great impact on the power of the photovoltaic module.

[0003] During welding, the soldering ribbon is required to be soft so that it can be better connected to the battery cell. However, if the soldering ribbon is too soft, its tensile strength will be reduced and it will be easy to break. Generally, a 35W soldering iron can meet the welding requirements. Therefore, when producing photovoltaic soldering ribbons, it is necessary not only to test the temperature of the soldering ribbon, but also to perform pressure and tensile tests. However, the current equipment can only perform a single test, which wastes time and affects production efficiency. Utility Model Content

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] This embodiment relates to a photovoltaic ribbon multi-inspection device, the overall structure of which is as follows: Figure 1 As shown, it includes a base 1, a pulling mechanism 2, a heating mechanism 3, and a pressing mechanism 4.

[0036] Among them, there are two groups of pulling mechanisms 2, which are rotatably set on the base 1 and located on both sides of the base 1. The photovoltaic welding ribbon is rolled up on the pulling mechanism 2. The heating mechanism 3 is fixedly set on the base 1 and located between the pulling mechanisms 2. The photovoltaic welding ribbon is inserted into the heating mechanism 3. The pressing mechanism 4 is lifted and lowered on the base 1 and located on one side of the heating mechanism 3. The photovoltaic welding ribbon is located at the bottom of the pressing mechanism 4.

[0037] It is worth mentioning that the pulling mechanism 2, the heating mechanism 3 and the pressing mechanism 4 are respectively located on the base 1. Such a setting can ensure that the welding strip can undergo multiple tests at the same time. The two sets of pulling mechanisms 2 are respectively located on both sides of the base 1. The two ends of the welding strip are respectively rolled up on the two sets of pulling mechanisms 2. The pulling mechanism 2 rotates outward to realize the pulling action. The two sets of pulling mechanisms 2 have the same structure. The heating mechanism 3 can heat the welding strip in all directions and more comprehensively detect the temperature that the photovoltaic welding strip can withstand. The pressing mechanism 4 is located on the upper part of the welding strip. When the pressing mechanism 4 contacts the base 1, the strength of the welding strip can be detected. With such a setting, the temperature, tensile strength and strength of the welding strip can be detected in one device.

[0038] Based on the above overall introduction, an exemplary structure of the photovoltaic ribbon multi-inspection equipment of this embodiment is as follows: Figure 2 As shown, the pulling mechanism 2 includes two support rods 201 fixedly arranged on the base 1 , a fixed shaft 202 rotatably arranged on the two support rods 201 , and a reel 203 rotatably arranged on the fixed shaft 202 , and a friction disk 204 is elastically arranged on the fixed shaft 202 .

[0039] It is worth mentioning that the support rod 201 is fixed on the base 1 by screws, and the fixed shaft 202 rotates on the two support rods 201 to ensure that the welding strip can be wound up. The reel 203 is fixed on the fixed shaft 202, and when the fixed shaft 202 rotates, the reel 203 is driven to wind up the welding strip, thereby achieving pulling. The friction disk 204 can generate friction with the reel 203, thereby controlling the pulling force of the reel 203, thereby more effectively detecting the pulling force.

[0040] As a preferred example, Figure 3 As shown, the fixed shaft 202 includes a sleeve 2021 rotatably arranged on one of the struts 201, and a roller 2022 rotatably arranged on the other strut 201, and the roller 2022 is inserted in the sleeve 2021 and rotatably arranged in the sleeve 2021. Specifically, the roller 2022 is inserted in the sleeve 2021, the sleeve 2021 rotates on one of the struts 201, and the roller 2022 rotates on the other strut 201, and the sleeve 2021 is a power source, which can drive the roller 2022 to rotate.

[0041] As a preferred embodiment, Figure 3As shown, the friction disc 204 is slidably disposed on the sleeve 2021 , a nut 205 is threadedly connected to the sleeve 2021 , a spring 206 is disposed between the nut 205 and the friction disc 204 , and a motor 207 is disposed on the support rod 201 to drive the sleeve 2021 to rotate. Specifically, the friction disc 204 and the sleeve 2021 are respectively provided with a sliding groove and a sliding block, such a setting can ensure that the friction disc 204 can only slide on the sleeve 2021, and cannot rotate on the sleeve 2021. The spring 206 supports the friction disc 204 to always abut against the reel 203. The nut 205 is threaded on the sleeve 2021, which can control the compression force of the spring 206, thereby controlling the friction force between the friction disc 204 and the reel 203. The motor 207 is fixedly installed on the support rod 201, and the motor 207 drives the sleeve 2021 to rotate. Since the friction disc 204 abuts against the reel 203, it can drive the roller 2022 to rotate. When the pulling force is greater than the friction force, the roller 2022 stops rotating and the sleeve 2021 rotates.

[0042] As a preferred embodiment, Figure 4 As shown, the heating mechanism 3 includes a heating tube 301 fixedly mounted on the base 1, and a cover 302 sleeved on the outside of the heating tube 301, and the photovoltaic welding strip is inserted inside the cover 302. A strip groove 303 is provided on the cover 302, and the heating tube 301 is coiled, and the photovoltaic welding strip passes through the heating tube 301 and the strip groove 303. It should be noted that the cover 302 is fixedly mounted on the top of the base 1 by screws, and the strip groove 303 provided on the cover 302 is for the welding strip to pass through. The heating of the heating tube 301 can detect the temperature of the welding strip. The heating tube 301 is coiled at least once, and is coiled around the welding strip to ensure that the welding strip can be heated in all aspects, thereby improving the detection quality.

[0043] As a preferred embodiment, Figure 5 As shown, the pressing mechanism 4 includes a frame 401 fixedly arranged on the housing, a driving cylinder 402 fixedly arranged on the frame 401, and a pressing plate 403 fixedly arranged on the driving cylinder 402, and the pressing plate 403 is in contact with the photovoltaic welding strip. Round rollers 5 are rotatably arranged on both sides of the frame 401 in the length direction, and the photovoltaic welding strip is wrapped around the round rollers 5.

[0044] It should be noted that the frame 401 spans across the base 1 and is fixed by screws. The driving cylinder can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, which can be selected according to actual conditions. The cylinder body of the driving cylinder 402 is fixed on the frame 401, and the driving rod of the driving cylinder 402 extends downward. The pressure plate 403 is fixed to the bottom of the driving rod. The welding strip passes through the bottom of the frame 401, and the pull rod is pressed down to contact the base 1, so as to detect the strength of the welding strip. The round rollers 5 are located on both sides of the frame 401. When detecting the pulling force, the friction between the frame 401 and the welding strip can be reduced.

[0045] The photovoltaic welding tape multi-inspection equipment in this embodiment can detect the pulling strength of the welding tape through the setting of the pulling mechanism 2, and can detect whether the welding tape is qualified to adapt to the temperature of the electric soldering iron through the setting of the heating mechanism 3, so as to ensure the quality of the welding tape. The pressure resistance of the welding tape can be detected through the setting of the pressing mechanism 4. The whole equipment can be detected at the same time, so as to improve work efficiency.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
