The support and limit assembly is movably connected in the limit grooves and is symmetrically arranged.

[0006] The support and limit assembly includes limit columns, adjusting rods, and support columns. The limit columns are rotatably connected between the inner upper wall and the inner bottom wall of the limit grooves. The adjusting rods penetrate through the side walls of the limit columns and are slidably arranged inside the limit columns. The support columns are rotatably connected to both ends of the adjusting rods, and the support columns are symmetrically arranged in pairs.

[0007] Further, a clamping groove is formed on the side wall of the support column.

[0008] Further, a limit airbag is fixedly connected to the inner side wall of the positioning opening, and the middle of the inner wall of the limit airbag is concave.

[0009] Further, support bars are fixedly connected to the upper and lower end faces of the connection frame, and the support bars are symmetrically distributed with the positioning opening as the center.

[0010] After adopting the above structure, the beneficial effects of the present utility model are as follows: For the limitation during the soldering of electronic components, one side of the circuit board is clamped through the symmetric clamping grooves, and the sliding connection frame supports the circuit board, improving the placement stability of the circuit board and making the connection frame correspond to the insertion position of the electronic components. The electronic components are inserted into the limiting airbag, and the pins are inserted into the circuit board. The limiting airbag positions the electronic components, and there is a certain distance between the bottom of the electronic components and the circuit board, improving the heat dissipation of the electronic components.

[0018] As Figures 1-5As shown in the figure, an electronic component connection and positioning device includes a connection frame 1 and a support and limit assembly 2. A positioning opening 3 is provided at the center of the end face of the connection frame 1. The positioning opening 3 is arranged in a long strip shape. Limit grooves 4 are provided on both sides of the connection frame 1. The limit grooves 4 are symmetrically distributed with the positioning opening 3 as the center. The support and limit assembly 2 is movably connected in the limit grooves 4. The support and limit assembly 2 is symmetrically arranged. Support strips 10 are fixedly connected to the upper and lower end faces of the connection frame 1. The support strips 10 are symmetrically distributed with the positioning opening 3 as the center. The connection frame 1 slides relative to the support and limit assembly 2 in the limit grooves 4 on both sides. The circuit board can be limited by the support and limit assembly 2. The connection frame 1 is slidably adjusted to support the bottom of the circuit board, so that the connection position between the connection frame 1 and the electronic component corresponds. The electronic component is clamped and positioned through the connection frame 1.

[0019] As Figure 2 , Figure 4 and Figure 5 shown in the figure, in order to achieve stable support for the circuit board and enable the position of the connection frame 1 to be slidably adjusted, the support and limit assembly 2 includes a limit post 5, an adjustment rod 6 and a support post 7. The limit post 5 is rotatably connected between the inner upper wall and the inner bottom wall of the limit groove 4. The adjustment rod 6 passes through the side wall of the limit post 5 and is slidably arranged inside the limit post 5. The support posts 7 are rotatably connected to both ends of the adjustment rod 6. The support posts 7 are arranged in pairs symmetrically. Clamping grooves 8 are provided on the side walls of the support posts 7. One side of the circuit board is clamped in the symmetric clamping grooves 8. The connection frame 1 can slide on the adjustment rod 6 through the limit post 5 to realize the movement adjustment of the connection frame 1 for supporting the circuit board at different positions. After flipping, the electronic component is limited through the connection frame 1.

[0020] As Figure 4 and Figure 5 shown in the figure, in order to achieve the positioning of the electronic component, a limit airbag 9 is fixedly connected to the inner side wall of the positioning opening 3. The middle part of the inner wall of the limit airbag 9 is concave. Support strips 10 are fixedly connected to the upper and lower end faces of the connection frame 1. The support strips 10 are symmetrically distributed with the positioning opening 3 as the center. Using the concave part on the inner side wall of the airbag, when the electronic component passes through the connection frame 1 and inserts its pins into the circuit board through the limit airbag 9, the electronic component is clamped in the limit airbag 9 to realize the clamping of the outer side walls of the electronic components with arc-shaped sides and straight sides. The circuit board is flexibly supported by the support strips 10, and the distance between the support strips 10 and the connection frame 1 is increased, so that the electronic component and the circuit board are kept at a certain distance to improve the welding quality.

[0021] During specific use, in the initial state, the adjusting rod 6 is in a symmetric and parallel state, and the connecting frame 1 is located in the middle of the adjusting rod 6. The operator clamps the circuit board through the clamping grooves 8 of the symmetric support columns 7 on the same side, supports the circuit board by using the connecting frame 1, and at the same time, the connecting frame 1 can be slidably adjusted relative to the circuit board. The flipping device flips the circuit board at the same time. Through the end face supporting device of the support column 7, the connecting frame 1 is slidably adjusted to make the connecting frame 1 correspond to the position where the electronic component is to be soldered. The electronic component is inserted into the positioning port 3, the pins pass through the circuit board, and the outer side wall of the electronic component is clamped and limited by the limiting airbag 9 to realize the positioning of the electronic component. The circuit board is supported by the support bar 10, so that a certain distance is left between the electronic component and the circuit board. The flipping device is used again to solder the pins on the circuit board, so as to realize the soldering of the electronic component on the circuit board while maintaining a certain height.
