Description

Technical Field

[0003] For example, Chinese Patent (Publication No.: CN217011306U) discloses an auxiliary positioning device for circuit board assembly. This auxiliary positioning device for circuit board assembly includes a box, a positioning mechanism, and a clamping mechanism. A motor is installed in the inner cavity of the box, and a first bevel gear is installed at the output end of the motor. The positioning mechanism includes a turntable, which is installed at the front end of a rotating shaft. Connecting rods are installed at both the upper and lower ends of the turntable. The clamping mechanism includes a first rotating wheel, which is installed on the rotating shaft. A transmission belt is sleeved on the outer side of the first rotating wheel. A first rotating rod and a second rotating rod are evenly arranged in the inner cavity of the box. This utility model achieves the positioning effect of the circuit board by using a rotating shaft to drive the turntable to rotate. The turntable pulls the two limiting plates on both sides towards the center of the box through the connecting rods. Compared with the manual positioning method, it greatly improves work efficiency and reduces errors in the assembly process. However, the circuit board assembly process requires processes such as welding. During the welding process, sparks and impurities such as solder slag are easily generated and enter the bevel gear, affecting the use of the equipment. Therefore, an efficient assembly auxiliary positioning device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an efficient assembly auxiliary positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] like Figures 1-4As shown, this utility model embodiment provides an efficient assembly auxiliary positioning device, including an assembly table 1, a positioning component 2 connected inside the assembly table 1, a placement platform 3 provided in the middle of the top of the assembly table 1, a vacuum cleaner 4 connected to the bottom of the assembly table 1, and a cold air blower 5 connected to one side of the assembly table 1.

[0025] The positioning component 2 includes a motor 201. The output end of the motor 201 is connected to a drive gear 202. A driven gear 203 meshes with one side of the drive gear 202. A bidirectional threaded rod 204 is welded to the inner side of the driven gear 203. A movable block 205 is threadedly connected to the outer side of the bidirectional threaded rod 204. A connecting block 206 is connected to the top of the movable block 205. A push rod 207 is connected to one side of the connecting block 206. A clamping plate 208 is connected to one end of the push rod 207. A rubber plate 209 is connected to one side of the clamping plate 208.

[0026] In this embodiment, the circuit board to be processed is placed on the placement platform 3, and the motor 201 is started. The motor 201 drives the drive gear 202 to rotate. The drive gear 202 meshes with the driven gear 203, driving the bidirectional threaded rod 204 to rotate. The reverse threads at both ends cause the movable block 205 to move synchronously towards each other, pushing the clamping plate 208 to clamp the circuit board, thus achieving automated positioning. The vacuum cleaner 4 can adsorb the solder slag and debris generated during the circuit board processing. The air cooler 5 blows air into the area of ​​the placement platform 3 through the filter screen 9. With the temperature sensor 15 monitoring the ambient temperature in real time, the heat generated by welding and other processes can be quickly reduced to prevent the circuit board components from being damaged by high temperature.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, specifically, the two ends of the bidirectional threaded rod 204 have opposite thread directions, there are two movable blocks 205, and a pressure sensor 16 is connected between the clamping plate 208 and the rubber plate 209.

[0028] A partition 13 is connected to the inner side of the assembly table 1. The top of the partition 13 is connected to the bottom of the motor 201. A limit rod 12 is connected to one side of the drive gear 202. One end of the limit rod 12 is rotatably connected to the inner side of the assembly table 1.

[0029] A dust suction port 10 is provided on one side of the top of the assembly table 1. A dust suction pipe 14 is connected to one side of the dust suction port 10. The other side of the dust suction port 10 is connected to the placement table 3. A waste box 11 is connected to the bottom of the inner side of the assembly table 1. One end of the dust suction pipe 14 is located above the waste box 11. The dust suction port 10, the dust suction pipe 14 and the vacuum cleaner 4 are interconnected. The waste box 11 and the bottom of the assembly table 1 are both mesh structures.

[0030] A filter 9 is provided on the other side of the top of the assembly table 1. The filter 9 is connected to the air cooler 5 and is located on one side of the placement table 3.

[0031] Temperature sensors 15 are provided on both sides of the inside of the assembly table 1. The temperature sensors 15 are located on both sides of the placement table 3. Limiting grooves 6 are opened on both sides of the inside of the assembly table 1. Springs 7 are connected inside the limiting grooves 6. One end of the springs 7 is connected to a connecting rod 8. There are four connecting rods 8. Both ends of each clamp 208 are connected to a connecting rod 8.

[0032] In this embodiment, the threaded transmission of the bidirectional threaded rod 204 and the movable block 205, along with the guiding structure of the limiting groove 6, spring 7, and connecting rod 8, ensures the precise movement trajectory of the clamping plate 208, reduces circuit board positioning deviation, and improves assembly accuracy. A pressure sensor 16 is installed between the clamping plate 208 and the rubber plate 209 to monitor the clamping force in real time and provide feedback to the control system, preventing circuit board deformation due to excessive tightness or displacement due to excessive looseness. The vacuum cleaner 4 at the bottom of the assembly table 1 uses the suction port 10 and suction pipe 14 to absorb welding slag generated during welding in real time. The waste box 11 can be easily disassembled. To prevent welding slag buildup from affecting mechanical transmission, the control system is connected to temperature sensor 15, pressure sensor 16, motor 201, and air cooler 5 via signals. When temperature sensor 15 detects that the temperature is too high, it sends a signal to air cooler 5 to control air cooler 5 to cool the placement platform 3. When pressure sensor 16 detects that the pressure is too high, it also sends a signal to control system to control motor 201 to reverse and drive the two movable blocks 205 to separate to both sides, preventing the circuit board from being deformed and causing certain economic losses.

[0033] The working principle of this utility model is as follows: First, the circuit board to be processed is placed on the placement platform 3. The motor 201 is started, which drives the drive gear 202 to rotate. The drive gear 202 meshes with the driven gear 203, which drives the bidirectional threaded rod 204 to rotate. The reverse threads at both ends cause the movable block 205 to move synchronously towards each other, pushing the clamping plate 208 to clamp the circuit board, thus achieving automated positioning. Then, the temperature on the placement platform 3 is detected in real time by the temperature sensor 15. When the temperature is too high, the air cooler 5 blows air into the area of ​​the placement platform 3 through the filter screen 9. With the temperature sensor 15 monitoring the ambient temperature in real time, the heat generated by welding and other processes can be quickly reduced to prevent the circuit board components from being damaged by high temperature. Finally, the vacuum cleaner 4 is started. The vacuum cleaner 4 uses the suction port 10 and the suction pipe 14 to absorb the welding slag generated by welding in real time. The waste box 11 can be easily disassembled and cleaned to avoid the accumulation of welding slag affecting the mechanical transmission.
