Abstract
Description
Technical Field
[0001] This utility model relates to a support fixture, specifically to an automatic positioning and welding support fixture for circuit board components. Background Technology
[0002] In the assembly and production of printed circuit boards (PCBs), accurately soldering various electronic components (such as resistors, capacitors, and integrated circuits) onto their corresponding pads on the PCB is a critical process. Traditional methods often rely on operators manually placing components or using simple jigs for positioning. This approach makes it difficult to ensure that each component pin is precisely aligned with the pads on the PCB, easily leading to misalignment and other problems. Especially in mass production, this cannot guarantee product consistency, resulting in a higher soldering defect rate and affecting product quality.
[0003] Existing welding positioning fixtures are typically designed specifically for circuit boards of a particular size and component layout. When a product model changes and requires welding circuit boards of different sizes or different types of components, the entire fixture or positioning module must be replaced. This process is not only time-consuming and labor-intensive, increasing production preparation time, but also significantly reduces the flexibility and efficiency of the production line. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an automatic positioning and welding support fixture for circuit board components, so as to solve the problems existing in the background art.
[0005] This utility model of an automatic positioning and welding support fixture for circuit board components is achieved through the following technical solutions, including a support base plate, a circuit board clamping structure, and a positioning and welding structure. The circuit board clamping structure is disposed on the support base plate, and the positioning welding structure is disposed above the circuit board clamping structure and corresponds to the position of the circuit board body located on the circuit board clamping structure. The bottom of the support base plate is equipped with synchronous electric lifting rods around its perimeter. The output shaft of the synchronous electric lifting rod passes through the support base plate and is connected to the positioning and welding structure. By driving the synchronous electric lifting rods, the positioning and welding structure is pressed onto the circuit board body.
[0006] As a preferred technical solution, the circuit board clamping structure includes a mounting base and a movable clamping base; The mounting base is located at one corner of the support base plate, and an inclined movable groove is provided at the other corner of the support base plate. The movable clamping base is guided and positioned in the movable groove by a movable block. The bottom of the support base plate is equipped with an electric telescopic rod, and the electric telescopic rod and the movable groove are on the same axis. The output shaft of the electric telescopic rod is connected to the push block below the movable block. The extension and retraction of the electric telescopic rod drives the movable clamping seat to move, so that it can adapt to square circuit boards of different sizes.
[0007] As a preferred technical solution, the positioning welding structure includes a lifting top plate and a positioning welding block; The lifting top plate is provided with an installation position. The positioning welding block is magnetically fixed to the installation position by magnets and magnetic components, and the lower end of the positioning welding block is flush with the bottom of the lifting top plate. As a preferred technical solution, the positioning welding block is arrayed with welding holes corresponding to the circuit board body. When the lifting top plate is placed on the circuit board body, the welding positioning between the circuit board components and the circuit board body is achieved through the positioning welding block above.
[0008] As a preferred technical solution, silicone pads are provided on the inner sides of both the mounting base and the movable clamping base, which serve to protect the edges and corners of the circuit board body.
[0009] As a preferred technical solution, the synchronous electric lifting rod is placed around the bottom of the support base plate, thereby forming support feet that support the support base plate.
[0010] The beneficial effects of this utility model are: This invention, by setting a positioning welding block with welding holes, can guide the pins of components to the circuit board; the synchronous electric lifting rod ensures that the lifting top plate and the positioning welding block can be smoothly pressed onto the circuit board, avoiding positioning deviations caused by tilting, thereby ensuring the uniformity of welding position and welding quality.
[0011] The circuit board clamping structure of this utility model uses an electric telescopic rod to drive the movable clamping seat to move, realizing the automatic clamping and fixing of square circuit boards of different sizes, enabling the fixture to adapt to a variety of products and improving the utilization rate of the equipment.

[0015] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.
[0016] like Figures 1-4 As shown, the present invention provides an automatic positioning and welding support fixture for circuit board components, comprising a support base plate 1, a circuit board clamping structure, and a positioning and welding structure. The circuit board clamping structure is disposed on the support base plate 1, and the positioning welding structure is disposed above the circuit board clamping structure and corresponds to the position of the circuit board body located on the circuit board clamping structure. The bottom of the support base plate 1 is provided with synchronous electric lifting rods 2 around its perimeter. The output shaft of the synchronous electric lifting rods 2 passes through the support base plate 1 and is connected to the positioning welding structure. By driving the synchronous electric lifting rods 2, the positioning welding structure is pressed onto the circuit board body.
[0017] The circuit board clamping structure includes a mounting base 3 and a movable clamping base 4. The mounting base 3 is located at the corner of the support base plate 1, and an inclined movable groove 5 is provided at the other corner of the support base plate 1. The movable clamping base 4 is guided and located in the movable groove 5 by the movable block 6. The bottom of the support base plate 1 is provided with an electric telescopic rod 8, and the electric telescopic rod 8 and the movable groove 5 are on the same axis. The output shaft of the electric telescopic rod 8 is connected to the push block 7 below the movable block 6. The extension and retraction of the electric telescopic rod 8 drives the movable clamping seat 4 to move, so that it can adapt to square circuit boards of different sizes.
[0018] The positioning and welding structure includes a lifting top plate 9 and a positioning and welding block 10. The lifting top plate 9 is provided with an installation position 11. The positioning welding block 10 is magnetically fixed to the installation position 11 by a magnet 13 and a magnetic component 14, and the lower end of the positioning welding block 10 is flush with the bottom of the lifting top plate 9. The positioning welding block 10 is provided with welding holes 12 corresponding to the main body of the circuit board. When the lifting top plate 9 is placed on the main body of the circuit board, the welding positioning between the circuit board components and the main body of the circuit board is achieved through the positioning welding block 10 above.
[0019] In addition, silicone pads are provided on the inner sides of the mounting base 3 and the movable clamping base 4, which serve to protect the edges and corners of the circuit board body.
[0020] In addition, the synchronous electric lifting rod 2 is placed around the bottom of the support base plate 1, thereby forming a support foot that supports the support base plate 1.
[0021] This invention, by setting a positioning welding block with welding holes, can guide the pins of components to the circuit board; the synchronous electric lifting rod ensures that the lifting top plate and the positioning welding block can be smoothly pressed onto the circuit board, avoiding positioning deviations caused by tilting, thereby ensuring the uniformity of welding position and welding quality.
