Technical Field

[0001] The invention relates to the technical field of circuit board welding, and in particular to a pin welding device for electronic component production which is easy to position. Background Art

[0002] Electronic components are basic units that have independent circuit functions and constitute circuits. With the development of electronic technology, the variety of components is increasing, the functions are becoming stronger, and the scope of involvement is also expanding. With the advancement of science, the size of electronic components is getting smaller and smaller, and the integration of electronic equipment is getting higher and higher. The difficulty of welding and processing electronic components such as chips is also increasing;

[0003] Currently, when workers are welding chips and other components, they need to weld the circuit board substrate to the pins of the electronic components. A slight shake during welding may cause problems such as misalignment of the component pins or cold soldering. At the same time, the substrate used for welding is light in weight and is easy to move during the welding process, affecting the welding effect. Therefore, we proposed a pin welding equipment for electronic component production that is easy to position. Summary of the invention

[0013] The bottom of the circular plate is rotatably connected to the top of the base plate, and the bottom of the base plate is rotatably connected to the transmission assembly. The output end of the transmission assembly passes through the base plate and is fixedly connected to the bottom center of the circular plate. The surface of the output end of the transmission assembly is rotatably connected to the inner side surface of the base plate. The positioning assembly is slidably limited to the side of the circular plate away from the base plate, and the positioning assembly is arranged directly above the V-shaped groove. The welding assembly is fixedly connected to the outer side surface of the base plate. The substrate of the circuit board is inserted into the V-shaped groove of the circular plate to fix the substrate, and then the electronic component is fixed to the center position of the substrate through the positioning assembly. Then, the welding assembly is used to weld the pins of the electronic component, and then the transmission assembly is started. The transmission assembly drives the circular plate to rotate, and the step is repeated to weld the next group of substrates and the pins of the electronic components, thereby realizing continuous processing. The V-groove with a V-shaped structure can fix substrates of different sizes and realize the welding of electronic components on substrates of various sizes. The movable positioning assembly can adjust the welding position according to the size of the substrate, and position the electronic component to the center of the substrate for welding the pins.

[0014] Furthermore, a plurality of V-shaped grooves are provided, and the plurality of V-shaped grooves are evenly distributed along the circumference of the circular plate. A plurality of positioning assemblies are provided, and the plurality of positioning assemblies are evenly distributed along the circumference of the circular plate. A plurality of V-shaped grooves are provided, and a plurality of substrates can be fixed at one time. When welding a substrate, the welded substrate can be unloaded and installed again.

[0015] Furthermore, limiting grooves are symmetrically provided on both sides of the V-shaped groove, and a spring plate is fixedly connected to the inner wall of the limiting groove, and the limiting groove is arranged in a parabolic shape. When a thinner substrate is processed, the substrate is inserted into the V-shaped groove to squeeze the spring plate, and the spring plate enters the limiting groove.

The positioning block slides inside the positioning groove to adjust the position of the electronic component, so that after substrates of different sizes are inserted into the V-shaped groove at different depths, the suction cup can still press the electronic component in the center of the substrate, and uniform deformation occurs on both sides of the bent plate. Under the action of elastic force, the telescopic rod is driven to move to both sides of the bent plate, thereby driving the positioning block to abut against the inner side of the positioning groove to reach a balanced state, so that the bent plate will not move at will after deformation, thereby ensuring the positioning effect.

The electric soldering iron 347 works to generate heat. The worker holds the sleeve 346 to drive the wire 343 and the electric soldering iron 347 to move. The electric soldering iron 347 leaves the placement tube 348 and solders the pins to the top of the substrate. After the soldering is completed, the electric soldering iron 347 is put back, and then the motor 351 is started. The output end of the motor 351 drives the shaft 352 to rotate. The rotation of the shaft 352 drives the circular plate 31 to rotate, and drives the parts on the top of the circular plate 31 to rotate. The circular plate 31 rotates, driving the protrusion 39 to rotate, and the protrusion 39 slides inside the annular groove 310. When the next V-shaped groove 32 is in front of the worker, the above steps are repeated to weld the next group of substrates and electronic component pins, thereby achieving continuous processing.
