Description

TECHNICAL FIELD

[0001] The application relates to the technical field of vehicle-mounted choke assembly, and discloses an automatic assembly equipment for vehicle-mounted choke production. BACKGROUND

[0002] The vehicle-mounted choke is a key element for inhibiting high-frequency electromagnetic interference in automobile electronics, and mainly comprises a choke coil, a magnetic core, an insulating framework, a pin and a packaging shell. The vehicle-mounted choke allows smooth passage of direct current required by a vehicle, and can efficiently block and absorb high-frequency noise generated by various electronic devices, so as to prevent mutual interference of in-vehicle systems, guarantee external electromagnetic compatibility and improve the anti-interference ability of the whole vehicle.

[0003] At present, in the assembly process of the vehicle-mounted choke, various assembly processes need to wind and assemble the copper wire of the choke coil. At present, many production lines still rely on manual or semi-automatic equipment, which is low in efficiency and difficult to adapt to flexible production of multiple varieties. Manual operation cannot accurately ensure the accuracy of the number of turns, the winding tension and the neatness of the wire arrangement, so that the vehicle-mounted choke has a great safety risk. Moreover, some semi-automatic equipment needs to be matched with multiple motors to adjust the rotating speed of the choke coil and the winding speed of the copper wire. Even if the main shaft motor and the wire arrangement servo motor are made to move synchronously through the controller instruction, the load change of each motor, the mechanical transmission gap and the response time of the respective servo drivers will all be different, which will cause slight asynchronization. The asynchronization will directly lead to uneven wire arrangement, wire stacking or tension fluctuation of the copper wire, and it is difficult to meet the production standard of ultra-high reliability of the vehicle-mounted choke.

[0039] The working principle of the present application is as follows:

[0040] The copper wire roller 20 is installed on the inner side of the ring 4, and the choke coil 19 without copper wire is inserted into the ring 4 through the opening 28, and the opening of the ring 4 is closed by the fixedly installed connecting plate 29.

[0041] The operator can wind the copper wire on the copper wire roller 20 into the choke coil 19, and the number of turns can be controlled to 3-5 turns; the transmission belt 25 is rotated by starting the servo motor 3, so that the ring 4 rotates on the side of the stand 2.
