Description

Technical Field

[0001] This utility model relates to the field of photovoltaic ribbon processing equipment, and in particular to a solder ball blocking device. Background Technology

[0002] Photovoltaic solder ribbon is an important component of solar photovoltaic modules. During the production of photovoltaic solder ribbon, a layer of tin needs to be plated on the surface of the pre-stretched copper ribbon. In the tin plating process, the copper ribbon first enters the tin bath, and after passing through a certain path, it vertically exits the liquid surface of the tin bath. In order to prevent uneven tin layer on the surface of the copper ribbon, a special tin bead blocking mechanism is required to scrape off the excess tin plating on the surface of the copper ribbon. At present, commonly used tin bead blocking devices have several different scraping ports according to the specifications of commonly used copper ribbons. However, over time, the number of solder ribbon models has increased, and the settings on the existing blocking devices cannot meet the actual requirements. If only one setting is set for each specification, some specifications are rarely used in actual production and also require a special matching tin bead blocking device. Therefore, it is necessary to redesign a tin bead blocking device that can be quickly and steplessly adjusted according to actual needs. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a solder ball blocking device that can steplessly adjust the distance between the scrapers according to the processing requirements of various specifications of solder strips, thereby improving the solder ball blocking effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A steplessly adjustable solder ball blocker is provided. The steplessly adjustable solder ball blocker is installed on a support structure above the solder pool. The steplessly adjustable solder ball blocker includes: a base, a fixed scraper, a movable scraper, a fixed scraper fixing mechanism, and a movable scraper driving mechanism. The fixed scraper is installed on the fixed scraper fixing mechanism, which is installed on one side of the upper surface of the base. The movable scraper is installed on the movable scraper driving mechanism, which is installed on the other side of the upper surface of the base. The fixed scraper and the movable scraper have the same shape, the same installation height, and opposite blades. After installation, the projected positions directly below the ends of the fixed scraper and the movable scraper on the same side partially exceed the range of the base. The movable scraper driving mechanism can drive the blade of the movable scraper to horizontally approach or move away from the blade of the fixed scraper.

[0005] In a preferred embodiment of this utility model, the fixed scraper fixing mechanism includes a fixed scraper fixing seat and a fixed scraper pressing block. The fixed scraper fixing seat has a fixed scraper mounting position on its top. The fixed scraper is placed in the fixed scraper mounting position, and one end of the fixed scraper extends out of the fixed scraper mounting position. The fixed scraper pressing block has a U-shaped structure, and one side of the U-shaped structure presses against the scraper body in the fixed scraper mounting position. The fixed scraper pressing block and the fixed scraper fixing seat are connected by bolts.

[0006] In a preferred embodiment of this utility model, the moving scraper drive mechanism includes a micrometer push rod, a bottom rail, a slider, a moving scraper fixing seat, and a moving scraper pressure block. The bottom rail is mounted on the base, and a push rod seat is provided inside the base. The micrometer push rod is fixedly mounted on the push rod seat. The slider is mounted on the bottom rail, and an L-shaped connecting push plate is provided inside the slider. The push head of the micrometer push rod is connected to the L-shaped connecting push plate, which can drive the slider to move horizontally reciprocally along the bottom rail. The moving scraper fixing seat is fixed to the slider by bolts. The top of the moving scraper fixing seat is provided with a moving scraper mounting position. The moving scraper is placed in the moving scraper mounting position, and one end of the moving scraper extends out of the moving scraper mounting position. The moving scraper pressure block has a U-shaped structure, and one side of the U-shaped structure presses against the scraper body in the moving scraper mounting position. The moving scraper pressure block is connected to the moving scraper fixing seat by bolts. Symmetrical slider limiting plates are provided on both sides of the bottom rail. Each slider limiting plate has a horizontal limiting groove. Limiting posts, matching the positions of the horizontal limiting grooves on the two slider limiting plates, are symmetrically installed on both sides of the slider. The micrometer push rod on the push rod seat is installed at the same height as the slider. In a preferred embodiment of this utility model, the length of the portion of the projection position directly below the end of the fixed scraper and the moving scraper on the same side that extends beyond the range of the base is not less than 3cm.

[0007] The beneficial effects of this utility model are as follows: This utility model is a further optimization of the structure of the existing solder ball blocking device. By installing a set of moving and fixed scrapers that can cooperate and adjust their distance from each other, the relative distance between the moving and fixed scrapers can be manually and steplessly adjusted precisely to meet the processing requirements of copper strips of various specifications, so as to achieve the best solder ball blocking effect. Moreover, the whole device has a simple structure and strong operational reliability. It is no longer necessary to remake a special matching solder ball blocking device because of changes in the specifications of the processed products, which effectively reduces the waste of production resources.

[0009] Please see Figure 1 The embodiments of this utility model include: A steplessly adjustable solder ball stopper is installed on a support structure above a solder bath. The steplessly adjustable solder ball stopper includes: a base 2, a fixed scraper 13, a movable scraper 12, a fixed scraper fixing mechanism, and a movable scraper driving mechanism. The fixed scraper 13 is installed on the fixed scraper fixing mechanism, which is installed on one side of the upper surface of the base 2. The movable scraper 12 is installed on the movable scraper driving mechanism, which is installed on the other side of the upper surface of the base 2. The fixed scraper 13 and the movable scraper 12 have the same shape, the same installation height, and opposite blades. After installation, the projected positions directly below the ends of the fixed scraper 13 and the movable scraper 12 on the same side partially extend beyond the range of the base 2. The movable scraper driving mechanism can drive the blade of the movable scraper 12 to horizontally approach or move away from the blade of the fixed scraper 13. In actual production, the solder strip 1 passes through the gap between the portion of the moving scraper 12 and the fixed scraper 13 that extends beyond the base 2. The size of the gap can be controlled by adjusting the distance between the moving scraper drive mechanism and the fixed scraper fixing mechanism. In this way, the solder balls scraped off during actual use can fall directly into the solder pool below and will not fall onto the base 2.

[0010] The fixed scraper fixing mechanism includes a fixed scraper fixing seat 4 and a fixed scraper pressing block 9. The fixed scraper fixing seat 4 has a fixed scraper mounting position on its top, and the fixed scraper 13 is placed in the fixed scraper mounting position. One end of the fixed scraper 13 extends out of the fixed scraper mounting position. The fixed scraper pressing block 9 has a U-shaped structure, and one side of the U-shaped structure presses against the scraper body in the fixed scraper mounting position. The fixed scraper pressing block 9 and the fixed scraper fixing seat 4 are connected by bolts 16. By using the U-shaped fixed scraper pressing block 9, the fixed scraper 13 can be pressed tightly onto the fixed scraper mounting position. The end extending out of the fixed scraper mounting position is used to scrape off the solder balls on the solder ribbon 1. In this way, the solder ribbon 1 will not hit the base 2 when passing through the scraping position, and the solder balls can fall directly into the solder pool when scraped off.

[0011] The moving scraper drive mechanism includes a micrometer push rod 3, a base rail 5, a slider 6, a moving scraper fixing seat 8, and a moving scraper pressure block 10. The base rail 5 is mounted on the base 2. A push rod seat 14 is provided on the inner side of the base. The micrometer push rod 3 on the push rod seat 14 is mounted at the same height as the slider 6. The micrometer push rod 3 is fixedly mounted on the push rod seat 14. The slider 6 is mounted on the base rail 5. An L-shaped connecting push plate 15 is provided on the inner side of the slider 6. The push head of the micrometer push rod 3 is connected to the L-shaped connecting push plate 15. The slider 6 can be driven to reciprocate horizontally along the bottom rail 5. The movable scraper fixing seat 8 is fixed to the slider 6 by bolts 16. The top of the movable scraper fixing seat 8 is provided with a movable scraper mounting position. The movable scraper 12 is placed in the movable scraper mounting position, with one end of the movable scraper 12 extending out of the movable scraper mounting position. The movable scraper pressure block 10 has a U-shaped structure, with one side of the U-shaped structure pressing against the scraper body in the movable scraper mounting position. The movable scraper pressure block 10 and the movable scraper fixing seat 8 are connected by bolts 16. In this way, by using the micrometer push rod 3, the movement distance of the movable scraper 12 can be finely adjusted when pushed to adapt to the size requirements of different specifications of welding strips 1.

[0012] Symmetrical slider limiting plates 11 are provided on both sides of the bottom rail 5. The slider limiting plates 11 are provided with horizontal limiting grooves. Limiting posts 7 are symmetrically installed on both sides of the slider 6, which match the positions of the horizontal limiting grooves on the two slider limiting plates 11. By installing the slider limiting plates 11, the sliding distance of the slider 6 can be limited, preventing the moving scraper 12 from colliding with the blade edge of the fixed scraper 13.

[0013] The length of the portion of the projection of the fixed scraper 13 and the movable scraper 12 directly below the end on the same side that extends beyond the base 1 is not less than 3cm. In actual implementation, the distance is generally about 5cm. In this way, the solder strip 1 passes through the middle position, about 2.5cm, so that when the solder balls are scraped off by the force and scattered around, they will not fall onto the base 2.

[0014] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
