[0023] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Please see Figure 1-6 This application provides a multi-station parallel soldering device: including a device body 1, a clamping mechanism for clamping a circuit board to be soldered; a soldering mechanism for realizing multi-point soldering operation; and a driving mechanism for driving the soldering mechanism to move in position.

[0026] The clamping mechanism includes a placement tray 12, three electric actuators 18, and a clamping block 19. The placement tray 12 is provided on the main body 1 of the device. A set of three electric actuators 18 are provided on the inner wall of the placement tray 12. The three electric actuators 18 are symmetrically distributed in a circle. The output end of each electric actuator 18 is connected to a clamping block 19. The circuit board is placed on the placement tray 12, and the circuit board is clamped and fixed by the cooperation of the electric actuators 18 and the clamping block 19.

[0027] To rapidly cool the solder joint, a miniature diaphragm pump 14 is installed on the main body 1 of the device. The miniature diaphragm pump 14 is connected to an air guide chamber 15, which is connected to several sets of air blowing pipes 13. In this embodiment, three sets are used, but this can be adjusted as needed in actual use. Through the cooperation of the miniature diaphragm pump 14 and the air blowing pipes 13, the solder joint can be rapidly cooled. Several control valves 16 are connected to the air guide chamber 15, each corresponding to one of the air blowing pipes 13, controlling the opening and closing of the air blowing pipes 13 and the airflow speed. A controller 4 is installed on the main body 1, and a display panel 5 is installed on the controller 4. The display panel 5 can display the real-time operating status of the control valves 16.

[0028] The soldering mechanism includes a mounting block 6 and several connectors 27. Two slots 7 are symmetrically distributed on the mounting block 6. Connectors 27 are engaged with the inner walls of the slots 7 via locking blocks. The engagement of the slots 7 and locking blocks initially fixes the connectors 27 in place. A turntable 25 is mounted on the connector 27, and a rotating rod 26 is mounted on the turntable 25. One end of the turntable 25 passes through the connector 27 and is connected to a screw 28. A slider 29 is threaded onto the outer wall of the screw 28, and the sidewall of the slider 29 abuts against the connector 27. A locking sleeve 30 is connected to the 7. The rotation rod 26 and the turntable 25 can drive the first screw 28 to rotate, which in turn can drive the slider 29 to slide inside the connector 27. The locking sleeve 30 can seal the junction between the slot 7 and the block. A locking rod 32 is inserted into the inner wall of the locking sleeve 30. A stop bar 34 is connected to the locking rod 32. A return spring 33 is installed on the locking rod 32. A pull rod 31 is connected to one end of the locking rod 32. The connector 27 can be further fixed to the mounting block 6 by the locking rod 32.

[0029] The drive mechanism includes a moving cavity 9, a motor 11, a second screw 22, a sliding block 23, and a first electric actuator 10. A support column 8 is threaded onto the main body 1, and the moving cavity 9 is threaded onto the support column 8. The support column 8 supports and fixes the moving cavity 9. The motor 11 is mounted on the moving cavity 9, and its output end passes through the outer wall of the moving cavity 9 and is connected to the second screw 22. The sliding block 23 is threaded onto the outer wall of the second screw 22. The motor 11 drives the second screw 22 to rotate, which in turn causes the sliding block 23 to slide horizontally inside the moving cavity 9.

[0030] A first electric push rod 10 is connected to the sliding block 23. The output end of the first electric push rod 10 is connected to the outside of the mounting block 6. Soldering tips 24 are connected to both the mounting block 6 and the slider 29. The first electric push rod 10 drives the mounting block 6 to perform soldering operation on the circuit board using the soldering tips 24, thereby realizing a dual-station soldering operation.

[0031] A partition plate 20 is connected to the inner wall of the main body 1 of the device. A temporary storage box 21 is set inside the main body 1 of the device. The temporary storage box 21 can be used for circuit boards that are temporarily waiting to be processed and circuit boards that have been processed, so that they can be easily retrieved or stored at one time later. Two boxes 2 are hinged to the main body 1 of the device. Each box 2 is connected to a handle 3. The boxes 3 can reduce dust from sticking to the circuit boards.

[0032] The working principle of this utility model is as follows: First, the operator installs a certain number of connectors 27 according to work requirements. First, the locking block is inserted into the slot 7 on the mounting block 6. Simultaneously, the locking sleeve 30 covers the connection between the locking block and the slot 7. Then, by rotating the pull rod 31 installed inside the locking sleeve 30, its stop rod 34 is aligned with the slot. Then, the return spring 33 causes the locking rod 32 to quickly spring back and insert into the mounting block 6, further securing the connector 27. Finally, according to work requirements, the rotating rod 26 and the turntable 25 work together to drive the first screw 28 to rotate, adjusting the slider 29 to a specific position. Then, the circuit board is placed on the placement tray. The circuit board is clamped and fixed by the cooperation of the second electric push rod 18 and the clamping block 19. Then, the second screw 22 is rotated by the motor 11, so that the sliding block 23 slides horizontally. Then, the first electric push rod 10 drives the mounting block 6 to move up and down, so that it can be soldered more flexibly. The soldering head 24 on the mounting block 6 and the slider 29 is used to solder the circuit board. Since the slider 29 can slide on the first screw 28, the distance between the two soldering heads 24 can be adjusted to meet the soldering needs of different positions. Finally, the soldering head on the circuit board is quickly cooled by the cooperation of the micro diaphragm pump 14 and the blower 13.
