[0003] For example, an electronic component welding device for a circuit board with a Chinese patent publication number of CN209647789U includes a base. A suction fan is fixedly arranged at the top end inside the base. Slide rails are fixedly arranged on both sides of the top end of the base.

[0004] When the circuit board welding device in the above patent is in use, it can only achieve the purpose of absorbing fumes. When the existing circuit board welding device is in use, since the electronic components need to be held by hand and there will be shaking or dropping phenomena when held by hand, the electronic components cannot be welded stably and accurately. Therefore, an improvement is needed for the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electronic component welding device for a circuit board to solve the problems raised in the above background technique.

The L-shaped support plate is fixedly installed at the top end of the displacement bracket. The positioning bolts are threadedly inserted at both ends of the displacement bracket.

[0007] Preferably, the bearing device includes a first hydraulic cylinder, a support bottom plate, a second hydraulic cylinder, a plastic plate, and a support top plate.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present invention: an electronic component welding device for a circuit board, including a support device 3. Symmetrically slidingly inserted at the top of the support device 3 is a positioning device 1. Slidingly sleeved at the bottom end inside the support device 3 is a bearing device 2. A circuit board 4 is placed on the top of the positioning device 1. The positioning device 1 includes a displacement bracket 5, positioning bolts 6, and an L-shaped support plate 7. The L-shaped support plate 7 is fixedly installed at the top of the displacement bracket 5. The positioning bolts 6 are threadedly inserted at both ends of the displacement bracket 5.

[0021] The bearing device 2 includes a first hydraulic cylinder 8, a support bottom plate 9, a second hydraulic cylinder 10, a plastic plate 11, and a support top plate 12. The first hydraulic cylinders 8 are symmetrically and fixedly installed at the top of the support bottom plate 9. The support top plate 12 is fixedly installed on the top of the first hydraulic cylinders 8. The second hydraulic cylinders 10 are fixedly installed at both ends of the support top plate 12. The plastic plate 11 is fixedly installed at the opposite ends of the second hydraulic cylinders 10. Since the material of the plastic plate 11 is plastic, damage to electronic components can be prevented.

[0022] The support device 3 includes a welding torch 13, a support front frame 14, guide rods 15, a driving motor 16, a lead screw 17, and a welding machine 18. The support front frame 14 is fixedly installed at the front end of the welding machine 18. The welding torch 13 is fixedly installed at the top of the welding machine 18. The driving motor 16 is fixedly installed at the side end of the support front frame 14. The lead screw 17 is fixedly installed at the center of the side end of the driving motor 16. The guide rods 15 are symmetrically and fixedly installed inside the support front frame 14, and the guide rods 15 are located on both sides of the lead screw 17. Since a square hole is provided at the center inside the support front frame 14, and the guide rods 15, the driving motor 16, and the lead screw 17 are located inside the square hole, the displacement of the support bottom plate 9 is allowed.

[0023] The support bottom plate 9 is threadedly sleeved on the lead screw 17. The displacement brackets 5 are symmetrically and slidingly inserted at the top of the support front frame 14, allowing the displacement brackets 5 to slide and adjust, facilitating adaptation to circuit boards 4 of different lengths.

[0024] Keys are symmetrically and fixedly installed at the bottom end of the displacement brackets 5, and slots are symmetrically provided at the top of the support front frame 14 to ensure that the displacement brackets 5 move in a straight line.

[0025] A plastic gasket is fixedly installed at the bottom end of the positioning bolt 6 to increase the friction between the positioning bolt 6 and the front support frame 14.

[0026] Working principle: When in use, first place the external electronic components on the top of the support top plate 12, then start the second hydraulic cylinder 10 to drive the plastic plates 11 to move towards each other until the plastic plates 11 contact the electronic components, so that the electronic components can be restricted and fixed. Subsequently, take the circuit board 4 and move it to a position flush with the L-shaped support plate 7, and then move the L-shaped support plate 7 to fit the two ends of the circuit board 4. Thus, the circuit board 4 can be placed on the opposite side ends of the L-shaped support plate 7. At the same time, the key on the bottom end of the displacement bracket 5 slides in the slot on the top of the front support frame 14, so as to ensure that the L-shaped support plate 7 moves in a straight line. Subsequently, when the displacement bracket 5 moves to the specified position, the positioning bolt 6 can be screwed and rotated to fit the top of the front support frame 14, so that the displacement bracket 5 can be restricted and fixed. At the same time, a plastic gasket is fixedly installed at the bottom end of the positioning bolt 6, so as to increase the friction between the positioning bolt 6 and the front support frame 14. Subsequently, the drive motor 16 can be started to drive the lead screw 17 to rotate. Since the inner center of the support bottom plate 9 is threadedly sleeved on the lead screw 17, when the lead screw 17 rotates, it can drive the support bottom plate 9 to move inside the front support frame 14. The two ends of the inner part of the support bottom plate 9 are slidably sleeved on the guide rod 15, so as to ensure that the support bottom plate 9 moves in a straight line. Until the support top plate 12 drives the legs of the electronic components to align with the mounting holes inside the circuit board 4, the first hydraulic cylinder 8 can be started to drive the support top plate 12 to move upward, so that the legs of the electronic components can penetrate the inside of the circuit board 4. Subsequently, the user can hold the welding torch 13 to weld the legs penetrating the circuit board 4, so that the legs can be welded to the circuit board 4, completing the welding work of the electronic components and the circuit board 4. Subsequently, the second hydraulic cylinder 10 can be opened again to release the electronic components, and then the first hydraulic cylinder 8 is opened to drive the support top plate 12 to move downward, so as to be separated from the electronic components. By repeating the above steps, multiple electronic components can be aligned with the bottom end of the circuit board 4, so as to facilitate the docking and welding of the electronic components and the circuit board 4 and complete the work.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
