[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1 to 4 As shown in this embodiment, a 180° rotating positioning soldering fixture includes a working platform 1 and a rotating cylinder 2. A product positioning base 3 is installed on the upper end of the working platform 1, and guide blocks 4 are provided on both sides of the product positioning base 3. The rotating cylinder 2 is located at the lower end of the working platform 1, and a circular turntable 5 is connected to the driving end of the rotating cylinder 2. A swing arm 6 is provided on the outer side of the circular turntable 5, and the circular turntable 5 is connected to the lower end of the working platform 1.
[0020] The product 15 is placed on the product positioning base 3 of the working platform 1, the two ends of the fin are outward, the tin injection hole of the fin is aligned with the guide block 4, the tin injection needle 11 on the outside is adjusted in position left and right under the action of the clamp along the installation plate, the height is controlled by rotating the lower end bolt 13, and then the tin injection needle 11 is inserted into the guide block 4 after alignment, the tin injection hole is formed by tin injection, then the tin injection needle 11 is moved out, the rotating cylinder 2 controls the swing arm 6 to rotate 180° through the circular turntable 5, the whole working platform 1 rotates 180°, the product 15 on the product positioning base 3 also rotates 180°, the tin injection hole on the other side of the fin is aligned with the guide block 4, and the tin injection needle 11 is convenient for the tin injection process on this side, the time cost of taking and placing materials is saved, and a second tin injection machine is no longer needed.
[0021] Specifically, the guide block 4 is provided with a horn mouth 7, the opening of the horn mouth 7 is outward, the center of the circular turntable 5 is aligned with the center of the product positioning base 3, the swing arm 6 is perpendicular to the length direction of the product 15, the product positioning base 3 is provided with three-section fin profiling grooves 8, the cylinder body of the rotating cylinder 2 is fixedly provided with a limiting block 9, the two ends of the limiting block 9 are provided with buffer needles 10, and the swing arm 6 swings between the buffer needles 10.
