Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a fixed platform for circuit board soldering. Background Technology

[0002] Circuit board soldering technology mainly uses tin-lead solder for welding, or simply tin soldering. The mechanism is as follows: during the tin soldering process, the solder, the workpiece, and the copper foil are heated together. The workpiece and the copper foil do not melt, which causes diffusion between the metals to form a metal alloy layer between the copper foil and the workpiece, thus connecting the copper foil and the workpiece together to obtain a strong and reliable solder joint.

[0003] Patent document CN109834359A discloses a welding platform for circuit board soldering, including a base. Two mounting plates are longitudinally symmetrically arranged on the left and right sides of the base, and two support plates are laterally symmetrically arranged on the two mounting plates. A mounting sleeve is fixedly sleeved on the outer side of the support plate and on the mounting plate. A telescopic rod is fixedly arranged on the mounting sleeve. Three support legs are connected by a connecting collar at equal angles, and the bottom of the three support legs is provided with support feet. A welding table is fixedly arranged on the top of the lifting sleeve. This welding platform is easy to disassemble and adjust.

[0004] In actual operation, the fixed platform for circuit board welding proposed in the above patent documents has several drawbacks. During the welding process, the welding torch head generates high temperature and heat on the surface of the circuit board, while the back of the circuit board is in close contact with the platform surface. This results in slow heat dissipation and cooling of the circuit board surface, and the waste fumes generated during the welding process cannot be treated in a timely manner, affecting the working environment.

A U-shaped rubber plate is fixed to the surface of the second locking block.

[0008] The surface of the rotating platform is provided with a heat dissipation mechanism, and the surface of the operating table is provided with a smoke removal mechanism.

[0009] In a preferred embodiment, the heat dissipation mechanism includes a distribution shell fixedly connected to the center of the upper surface of the rotating platform, an intake fan fixedly disposed on the upper surface of the distribution shell, and the air outlet of the intake fan extending into the interior of the distribution shell.

The height of the first locking block corresponds to that of the second locking block.

[0013] In a preferred embodiment, the smoke removal mechanism includes a mounting bracket fixed to the surface of the operating table. The front of the mounting bracket has a rectangular smoke extraction hole, and a filter screen is fixed to the inner wall of the smoke extraction hole. A smoke collection hood is fixed to the back of the mounting bracket, and an air suction pump is fixedly installed on the back of the mounting bracket. The input end of the air suction pump extends into the interior of the smoke collection hood. A smoke baffle is fixedly connected to the front of the mounting bracket, and the position of the smoke baffle corresponds to the smoke extraction hole.

[0014] In a preferred embodiment, the upper surface of the operating table is provided with a mounting groove, the inner wall of the mounting groove is rotatably connected to a support column, the top end of the support column is fixedly connected to the center of the lower surface of the rotating platform, and a drive motor is fixedly installed on the inner wall of the mounting groove.

Furthermore, by utilizing the stepped limiting groove on the surface of the second clamping block, circuit boards of different thicknesses can be limited, improving the stability of the circuit board during the welding process.

[0018] Secondly, by setting a heat dissipation mechanism on the surface of the rotating platform, air can be introduced into the split housing by the intake fan and into the clamping bottom housing by the air guide pipe. Then, the strip-shaped air outlet on the surface of the clamping bottom housing can be used to blow air to dissipate heat on the back of the circuit board, reducing the heat generated by the high temperature of the soldering gun head on the surface of the circuit board. It can also make the solder wire at the solder joint on the back of the circuit board cool and solidify quickly, which helps to improve the efficiency of the soldering process.

[0019] Thirdly, by setting up a smoke removal mechanism, an air pump can be used to draw air into the inside of the fume hood during the circuit board welding process, thereby creating a negative pressure inside the fume hood. The welding fumes above the circuit board are then drawn in and collected through the smoke extraction holes, while the filter screen filters the particles in the fumes, achieving the effect of collecting and filtering welding fumes.

Then, slide the first adjusting sleeve 304 and the second adjusting sleeve 308 on the surface of the first adjusting square rod 303, thereby adjusting the distance between the two first locking blocks 305. Then, place one end of the circuit board inside the limiting slot 306, and then release the handle 314. Under the reset action of the compression spring 313, the rubber plate 310 on the surface of the second locking block 309 clamps and limits the other end of the circuit board, thereby achieving clamping and fixing of the circuit board.

The rotating worm gear 9 drives the support column 6 and the rotating platform 2 to rotate, which can rotate the circuit board to the position of the fume removal mechanism 5. Then, the welding torch is used to perform spot welding on the surface of the circuit board. At the same time as welding, the intake fan 402 can be used to supply air to the inside of the diversion shell 401, and the air can be input into the inside of the clamping bottom shell 301 through the air guide duct 403. The strip-shaped air outlet 404 is used to dissipate heat on the back of the circuit board, so that the solder joints on the back of the circuit board can be cooled quickly. At the same time as welding, the suction pump 505 can be used to suck air into the inside of the fume hood 504, and the fume generated by welding can be removed by the smoke extraction hole 502 on the surface of the mounting bracket 501. The filter screen 503 is used to filter the fume before it is discharged, thus achieving the purpose of welding fume treatment.
