Description

Technical Field

[0001] The utility model relates to the technical field of electronic component production, in particular to an electronic component welding device. Background Art

[0002] Electronic devices refer to devices made by utilizing and controlling the laws of electron motion in a vacuum, gas or solid. They are divided into electric vacuum devices, gas-filled tube devices and solid-state electronic devices. They perform rectification, amplification, modulation, oscillation, frequency conversion, phase locking, control and correlation functions in analog circuits. When soldering electronic components to printed circuit boards, a soldering device will be required.

[0003] The existing electronic component welding device requires the circuit board to be placed on a workbench and fixed and clamped. When electronic components need to be welded on both sides of the circuit board, the staff needs to take out the circuit board, turn it over, and fix and clamp the circuit board again, which reduces the welding efficiency. In addition, since the circuit board is currently mostly clamped by hard clamping, and the circuit board is overall thin, the hard clamping of the traditional clamp can easily cause damage to the circuit board. Therefore, it is necessary for us to improve the existing equipment to overcome the above defects. Utility Model Content

[0004] The utility model aims to provide an electronic component welding device, which has the advantages of being able to flexibly clamp a circuit board and flip the circuit board, thereby solving the problem that it is difficult to flexibly clamp the circuit board during welding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic component welding device, comprising a welding mechanism, wherein a clamping mechanism is provided on the surface of the welding mechanism;

[0006] The clamping mechanism includes a base plate, two side plates are fixed on the top of the base plate, the surface of the side plate is rotatably connected with positive and negative screw rods, the surface of the positive and negative screw rods is threadedly connected with a sliding plate, a buffer spring is fixed on the surface of the sliding plate, a connecting frame is fixed on the surface of the buffer spring, a combined plate is fixed on the surface of the connecting frame, a clamping shell is provided on one side of the combined plate, a rotating joint is installed on the surface of the clamping shell, a clamping pad is connected to the surface of the clamping shell, an air pump is fixed on the top of the base plate, an air pipe is connected to the surface of the air pump, a corrugated pipe is installed on the surface of the air pipe, the surface of the air pipe passes through the combined plate and is connected to the rotating joint, a limiting rod is fixed on the surface of the clamping shell, and an arc groove is opened on the surface of the combined plate.

[0007] As a preferred electronic component welding device of the utility model, a clamping sleeve is threadedly connected to the surface of the limiting rod.

[0008] As a preferred electronic component welding device of the utility model, the buffer spring is a damping spring.

[0009] As a preferred electronic component welding device of the utility model, a supporting shell is fixed on the top of the base plate.

[0010] As a preferred electronic component welding device of the utility model, a guide rail is fixed on the top of the base plate, and the sliding plate is slidably connected to the surface of the guide rail.

[0011] As a preferred electronic component welding device of the present invention, the clamping pad is made of rubber material.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model enables the circuit board to be flexibly clamped by the clamping mechanism, and can be turned over without releasing the clamping. First, the circuit board is placed between the clamping shells on both sides, and then the positive and negative threaded screws are rotated so that the two sliding plates are affected by the threads on the surface of the positive and negative threaded screws and begin to move toward each other, so that the surface of the clamping pad can contact the surface of the circuit board. At this time, the positive and negative threaded screws are continuously rotated to compress the clamping pad and the buffer spring at the same time, so as to have a buffering effect on the circuit board and avoid damage to the circuit board by hard clamping. Then, the air pump is started to input compressed gas into the clamping shell through the air pipe, and the compressed gas is compressed. The injection of the body will cause the clamping pad to expand, so that the flexible clamping pad can be evenly attached to the surface of the circuit board. Through this design, it can effectively avoid local stress concentration that may be caused by hard clamping, help maintain the overall stability of the circuit board, and prevent damage to the circuit board during the clamping process. After that, the circuit board can be welded through the welding mechanism. When the welding is completed and needs to be turned over, the clamping shell is rotated so that the limit rod can slide on the surface of the arc groove, so that the clamping shells on both sides can drive the circuit board to turn over synchronously, thereby achieving the effect of turning the circuit board without releasing the clamp, thereby improving the circuit board welding efficiency.

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 4 , an electronic component welding device, comprising a welding mechanism 1, a clamping mechanism 2 is arranged on the surface of the welding mechanism 1;

[0020] The welding mechanism 1 is used for welding the circuit board, and the clamping mechanism 2 enables the circuit board to be flexibly clamped and turned over without releasing the clamping.

[0021] The clamping mechanism 2 includes a bottom plate 201, two side plates 202 are fixed on the top of the bottom plate 201, the surface of the side plate 202 is rotatably connected with a positive and negative threaded rod 203, one end of the positive and negative threaded rod 203 passes through one side of the side plate 202 and is fixed with a handle, the surface of the positive and negative threaded rod 203 is threadedly connected with a sliding plate 204, the surface of the sliding plate 204 is fixed with a buffer spring 205, the surface of the buffer spring 205 is fixed with a connecting frame 206, the surface of the connecting frame 206 is fixed with a combination plate 207, and one side of the combination plate 207 is provided with a clamping shell 209 A rotating joint 208 is installed on the surface of the clamping shell 209, and a clamping pad 210 is connected to the surface of the clamping shell 209. An air pump 211 is fixed on the top of the bottom plate 201. The surface of the air pump 211 is connected to an air pipe 212. A bellows 213 is installed on the surface of the air pipe 212. The surface of the air pipe 212 passes through the combined plate 207 and is connected to the rotating joint 208. A limiting rod 214 is fixed on the surface of the clamping shell 209, and an arc groove 218 is opened on the surface of the combined plate 207. The limiting rod 214 is slidably connected to the surface of the arc groove 218;

[0022] First, place the circuit board between the clamping shells 209 on both sides, then rotate the positive and negative threaded rods 203, so that the two sliding plates 204 are affected by the surface threads of the positive and negative threaded rods 203 and begin to move toward each other, so that the surface of the clamping pad 210 can contact the surface of the circuit board. At this time, continue to rotate the positive and negative threaded rods 203 to compress the clamping pad 210 and the buffer spring 205 at the same time, so as to have a buffer effect on the circuit board and avoid hard clamping to damage the circuit board. Then start the air pump 211 to input compressed gas into the clamping shell 209 through the air pipe 212. The injection of compressed gas will cause the clamping pad 210 to The expansion allows the flexible clamping pad 210 to evenly fit on the surface of the circuit board. This design can effectively avoid local stress concentration that may be caused by hard clamping, help maintain the overall stability of the circuit board, and prevent damage to the circuit board during the clamping process. The circuit board can then be welded through the welding mechanism 1. When the welding is completed and needs to be turned over, the clamping shell 209 is rotated so that the limit rod 214 can slide on the surface of the arc groove 218, so that the clamping shells 209 on both sides can drive the circuit board to turn over synchronously, thereby achieving the effect of turning over the circuit board without releasing the clamp, thereby improving the circuit board welding efficiency.

[0023] Furthermore, a clamping sleeve 215 is threadedly connected to the surface of the limiting rod 214;

[0024] After the clamping shell 209 drives the limiting rod 214 to slide inside the arc groove 218, the clamping sleeve 215 can be twisted into the surface of the limiting rod 214 and the clamping sleeve 215 can be continuously rotated so that the surface of the clamping sleeve 215 fits with the combination plate 207, so that the limiting rod 214 can be affected by the friction force to obtain a limiting effect, thereby preventing the clamping shell 209 from rotating during the welding process.

[0025] Further, the buffer spring 205 is a damping spring;

[0026] The damping spring can absorb the impact and vibration during the movement, making the movement of the connecting frame 206 smoother and more stable, which can reduce the dislocation or damage caused by vibration during the positioning and welding of electronic components.

[0027] Furthermore, a support shell 216 is fixed on the top of the bottom plate 201;

[0028] The limiting rod 214 can protect the positive and negative threaded rods 203 to prevent the circuit components from colliding with the surface of the positive and negative threaded rods 203 when they fall, so that the circuit components and the positive and negative threaded rods 203 are not easily damaged.

[0029] Furthermore, a guide rail 217 is fixed on the top of the bottom plate 201, and the sliding plate 204 is slidably connected to the surface of the guide rail 217;

[0030] The sliding plate 204 can move on the surface of the guide rail 217, so that the sliding plate 204 can obtain a guiding effect and avoid the sliding plate 204 from rotating itself when moving.

[0031] Further, the clamping pad 210 is made of rubber;

[0032] The rubber material has excellent flexibility and elasticity, and can closely conform to the contours of circuit boards and components when pressure is applied by expansion, ensuring uniform force, while quickly returning to its original shape after the pressure is released, making it easy to reuse and not prone to damage.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
