Description

Technical Field

[0001] This utility model relates to the field of photovoltaic production technology, and in particular to a tooling for cleaning flux crystallization in a guide groove. Background Technology

[0002] Photovoltaic modules, also known as solar cell modules, are used to directly convert sunlight into electrical energy. Ground-mounted photovoltaic systems extensively use silicon solar cells with a silicon substrate. Photovoltaic cells have many advantages, and with the rapid development of the photovoltaic field, they are widely used.

[0003] In the production of photovoltaic modules using automated stringing machines, stringing the solar cells is a crucial step. Before stringing, the solder ribbon needs to be pulled out and laid on the main busbars of the solar cells. During production, the solder ribbon is pulled out rapidly; however, this rapid pulling can cause the ribbon to vibrate and fail to accurately cover the main busbars. Therefore, to prevent ribbon vibration and misalignment, a solder ribbon guide groove is typically added after the ribbon is pulled out.

[0004] However, after a period of use, flux crystals may form inside the welding strip guide groove, affecting production and making cleaning difficult. Utility Model Content

[0033] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0034] The specific structure is as follows: Figure 1 and Figure 2 As shown.

[0035] This embodiment provides a tooling for cleaning flux crystals in a guide groove, including: a handle 1, a scraper 2, and a substrate 3; both the handle 1 and the scraper 2 are connected to the substrate 3; the handle 1 is located on the back of the substrate 3 and is used for holding, while the scraper 2 is located on the front of the substrate 3 and is used to scrape off flux crystals in the guide groove.

[0036] In this embodiment, after the scraper 2 is inserted into the guide groove by grasping the handle 1, the handle 1 is pulled along the extension direction of the guide groove to scrape off the flux crystals in the guide groove. The tooling for cleaning flux crystals in the guide groove has a simple structure and is easy to operate. It is convenient and quick to clean the flux crystals in the guide groove, thereby improving production efficiency.

[0037] In the optional technical solution of this embodiment, the thickness of the front end of the scraper 2 is less than the thickness of the rear end along the direction from the back side to the front side of the substrate 3. This facilitates the insertion of the scraper 2 into the guide groove.

[0038] In the optional technical solution of this embodiment, the scraper 2 is made of non-metallic material. This avoids reaction with flux and improves service life.

[0039] In the optional technical solution of this embodiment, multiple scraper blades 2 are arranged side by side with intervals. This allows for the simultaneous removal of flux crystals in multiple guide grooves, improving cleaning efficiency.

[0040] In the optional technical solution of this embodiment, the scraper 2 is arranged in two rows, and the two rows of scraper 2 correspond one to one. Along the extension direction of the guide groove, the flux crystals in each guide groove are cleaned by two scraper 2 one in front and one behind, ensuring that the cleaning is thorough.

[0041] In the optional technical solution of this embodiment, the substrate 3 is I-shaped, and the two rows of scrapers 2 are located at opposite ends of the substrate 3.

[0042] In this embodiment, the substrate 3 has a simple structure, high structural stability, and is lightweight, making it easy to use. In addition, the two rows of scrapers 2 are located at opposite ends of the substrate 3, maximizing the use of space on the substrate 3 and improving the effective utilization rate of the substrate 3.

[0043] In the optional technical solution of this embodiment, a baffle 4 is also included; a slot is provided on the side of the substrate 3, and the slot passes through the front of the substrate 3; the scraper is fixed to the slot and partially extends out of the front of the substrate 3; the baffle 4 is connected to the substrate 3 and covers the slot opening.

[0044] In this embodiment, the scraper 2 is inserted into the slot from the side of the substrate 3, making installation convenient. The scraper 2 extends beyond the front of the substrate 3. This can be achieved by either fixing the scraper 2 to the substrate 3 to ensure stability, or by making the rear end of the scraper 2 thicker and the front end thinner, allowing the front end to pass through the slot and through the opening on the front of the substrate 3, while preventing the rear end from exiting the opening, thus ensuring stability. After the scraper 2 is installed, a baffle 4 seals the slot to prevent the scraper from falling off the side of the substrate 3, i.e., from the slot opening. This effectively ensures the stability of the scraper 2 and facilitates installation.

[0045] In the optional technical solution of this embodiment, the baffle 4 includes a connecting part 5 and a sealing part 6, and the connecting part 5 and the sealing part 6 form an L-shaped structure; the connecting part 5 is connected to the back side of the substrate 3, and the sealing part 6 is located on the side of the substrate 3 and covers the slot opening. The baffle 4 is connected to the back side of the substrate 3 through the connecting part 5, which facilitates installation. At the same time, the sealing part 6 can cover the slot opening. The sealing part 6 abuts against the side wall of the substrate 3 without damaging the structure of the side wall of the substrate 3, making it easy to manufacture and more durable.

[0046] In the optional technical solution of this embodiment, the connecting part 5 is provided with multiple notches 7 at intervals. This reduces the weight of the connecting part 5, thereby making the whole unit lighter and easier to use.

[0047] In the optional technical solution of this embodiment, the handle 1 is U-shaped, and both ends of the handle 1 are provided with flanged portions 8, which are connected to the back of the substrate 3.

[0048] In this embodiment, the handle 1 has a simple structure, is easy to hold, and is easy to connect and stable through the flange 8.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
