[0026] Example

[0027] like Figure 1-4 As shown in the figure, this application provides an automatic pin assembly device, including a base 1. The base 1 is provided with a support 2, a pin feeding mechanism 3, a drive mechanism 4, a pin picking mechanism 5, and a pin assembly mechanism 6. The support 2 is provided with a motor 7 and a positioning mechanism 8. The output end of the motor 7 is provided with a fixture 9. The drive mechanism 4 drives the pin picking mechanism 5 and the pin assembly mechanism 6 to reciprocate synchronously between the pin feeding mechanism 3 and the fixture 9.

[0028] In use, the gear ring and plastic shell are first manually loaded into fixture 9. Then, the start switch is pressed, and the positioning mechanism 8 positions the gear ring and plastic shell. After the pin picking mechanism 5 takes out the material from the pin feeding mechanism 3, the drive mechanism 4 drives the pin picking mechanism 5 and the pin assembly mechanism 6 to move synchronously above fixture 9. The pin assembly mechanism 6 assembles the pin between the gear ring and the plastic shell, completing the first assembly. Subsequently, the drive mechanism 4 drives the pin picking mechanism 5 and the pin assembly mechanism 6 to move synchronously above the pin feeding mechanism 3. The motor 7 drives fixture 9 to rotate at a set angle, and fixture 9 drives the gear ring and plastic shell to rotate synchronously. After the pin picking mechanism 5 takes out the pin again, the drive mechanism 4 drives the pin picking mechanism 5 and the pin assembly mechanism 6 to move synchronously above fixture 9 again. The pin assembly mechanism 6 assembles the pin between the gear ring and the plastic shell again, completing the second assembly. After the assembly is completed, the assembled product is removed manually.

[0029] In this embodiment, the positioning mechanism 8 includes a first cylinder 10 and a pressure block 11. The first cylinder 10 is disposed on the support 2. The first cylinder 10 drives the pressure block 11 to move closer to or away from the support 2. The fixture 9 is located between the support 2 and the pressure block 11.

[0030] In use, after the gear ring and plastic housing are manually installed into the fixture 9, the first cylinder 10 drives the pressure block 11 to move towards the side closer to the support 2. The pressure block 11 is used to position the gear ring and plastic housing. After the pin is assembled, the first cylinder 10 drives the pressure block 11 to move away from the support 2, and the assembled product can be removed.

[0031] In this embodiment, the drive mechanism 4 includes a first bracket 12, a first linear module 13, a second bracket 14, a second linear module 15, and a third bracket 16. The first bracket 12 is mounted on the base 1, the first linear module 13 is mounted on the first bracket 12, the second bracket 14 is mounted on the first linear module 13, the second linear module 15 is mounted on the second bracket 14, and the third bracket 16 is mounted on the second linear module 15. The pin picking mechanism 5 and the pin assembly mechanism 6 are both mounted on the third bracket 16.

[0032] In use, the first linear module 13 drives the second bracket 14 to reciprocate, and the second linear module 15 drives the third bracket 16 to move up and down, so as to realize the synchronous movement of the pin picking mechanism 5 and the pin assembly mechanism 6 in the horizontal and vertical directions.

[0033] In this embodiment, the pin picking mechanism 5 includes a first lifting block 17 and a suction nozzle 18. The first lifting block 17 is mounted on the third bracket 16, and the suction nozzle 18 is mounted on the first lifting block 17. The suction nozzle 18 is a special suction nozzle for automatic screw machines.

[0034] In use, the first linear module 13 drives the second bracket 14 to move above the pin feeding mechanism 3, and the second linear module 15 drives the third bracket 16 to move down, so that the suction nozzle 18 is close to the pin. Under the action of the external air source, the suction nozzle 18 picks up the pin. Then, the second linear module 15 drives the third bracket 16 to move up to the initial position. After the first linear module 13 drives the second bracket 14 to move above the fixture 9, the second linear module 15 drives the third bracket 16 to move down, so that the suction nozzle 18 abuts against the plastic shell and is concentric with the mounting hole on the plastic shell. Finally, the pin assembly mechanism 6 assembles the pin in the suction nozzle 18 between the gear ring and the plastic shell.

[0035] In this embodiment, the pin assembly mechanism 6 includes a second cylinder 19, a first slide rail 20, a first slider 21, a second lifting block 22, and a ejector pin 23. The second cylinder 19 and the first slide rail 20 are both mounted on the third bracket 16. The first slider 21 is mounted on the first slide rail 20. The second lifting block 22 is fixedly connected to the first slider 21. With the cooperation of the first slide rail 20 and the first slider 21, the smoothness of the operation of the second lifting block 22 is ensured. The ejector pin 23 is mounted on the second lifting block 22, and one end of the ejector pin 23 away from the second lifting block 22 extends into the interior of the suction nozzle 18.

[0036] During pin assembly, the second cylinder 19 drives the second lifting block 22 to move down, and the second lifting block 22 drives the ejector pin 23 to move synchronously. The ejector pin 23 presses the pin between the gear ring and the plastic housing. After the pin is installed, the second cylinder 19 drives the second lifting block 22 to move up to the initial position, and the second lifting block 22 drives the ejector pin 23 to move up synchronously.

[0037] In this embodiment, in order to optimize the assembly process, protect the components, and improve the stability and service life of the final product, an oil injection mechanism 24 is provided on the third bracket 16. The oil injection mechanism 24 includes a third cylinder 25, a second slide rail 26, a second slider 27, a third lifting block 28, and an oil reservoir 29. The third cylinder 25 and the second slide rail 26 are both provided on the third bracket 16. The second slider 27 is provided on the second slide rail 26. The third lifting block 28 is fixedly connected to the second slider 27. With the cooperation of the second slide rail 26 and the second slider 27, the smoothness of the operation of the third lifting block 28 is ensured. The oil reservoir 29 is provided on the third lifting block 28. An oil filling head 30 and a metering valve are provided at the bottom of the oil reservoir 29.

[0038] In use, the third cylinder 25 drives the third lifting block 28 to move down, so that the oil filling head 30 moves to the pin position for oil filling. The oil filling amount is set and controlled. After the oil filling is completed, the third cylinder 25 drives the third lifting block 28 to move up to the initial position. The third lifting block 28 drives the oil storage cylinder 29 and the oil filling head 30 to move up synchronously.

[0039] In this embodiment, there are two supports 2, and the pin feeding mechanism 3 is located between the two supports 2. When it is necessary to perform material loading and unloading operations on one of the supports 2, the gear ring and plastic shell on the other support 2 can be assembled with pins, thereby further improving production efficiency.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
