The voice coil motor to be cleaned is placed in the bearing groove 821 matched in shape, and the edges of the bearing plate 820 are limited in the corresponding limiting spaces of the limiting structure. The same support seat 810 can fix a plurality of bearing plates 820 arranged at intervals through the limiting spaces, and the bearing fixture 800 is placed on the transfer trolley 900 from the position of the feeding port 111 of the shell 100 and is pushed into the feeding area 110 corresponding to the position of the feeding port 111.

[0051] Step S2, the transfer mechanism 600 picks up the bearing frame 700 in the feeding area 110 and transfers to above the first cleaning mechanism 200, and then the bearing frame 700 and the bearing fixture 800 loaded with the workpiece in the bearing frame 700 are placed in the first cleaning mechanism 200, and the voice coil motor is cleaned by the vibration bubble method.

[0052] In the above step S2, the transfer mechanism 600 can be moved to the feeding area 110 along the arrangement direction of the upper guide rod 611 and the lower guide rod 612 and located above the bearing frame 700. The pickup part 620 capable of moving along the lifting guide rail 614 can extend into the bearing frame 700. After the driving unit 622 is started, the two supporting plates 623A are horizontally unfolded along the pickup seat 621, so that the pickup hooks 623B extend into the through port 710 and hook the through port 710. The sliding table 613 moves to transfer the bearing frame 700 into the first cleaning tank 230 and prevent it from being on the first hollow support 250. The vibration machine 210 below the first cleaning tank 220 is started to vibrate the first cleaning tank 220 at a fixed frequency. The pure water in the first cleaning tank 230 can be heated by the first heating pipe 260, and the pure water bubbles during the vibration cleaning process. The workpiece in the first cleaning tank 230 achieves the dust removal purpose after experiencing the bubble vibration.

[0053] Step S3, after the cleaning in the first cleaning mechanism 200 is completed, the transfer mechanism 600 picks up the bearing frame 700 above the first cleaning mechanism 200 and transfers to above the second cleaning mechanism 300, and then the bearing frame 700 is placed on the second hollow support 340 in the second cleaning mechanism 300. The lifting driving motor 355 in the lifting mechanism 350 is started, the moving rod 351B can move up and down in the guide block 351A, so that the second hollow support 340 loaded with the bearing frame 700 can move up and down in the pure water in the second cleaning tank 311. In addition to the bubble function described above, the workpiece is further washed by the pure water in a more detailed manner.

[0054] Step S4, after the cleaning in the second cleaning mechanism 300 is completed, the transfer mechanism 600 picks up the material frame 700 above the second cleaning mechanism 300 and transfers to the centrifugal spin-drying mechanism 400, and then places the material frame 700 into the spin-drying frame 420 of the centrifugal spin-drying mechanism 400. The rotation driving motor 432 drives the driving wheel 433 to rotate, and the driven wheel 434 connected with the transmission belt 435 can also rotate horizontally, so that the spin-drying frame 420 can rotate horizontally in the spin-drying inner cavity 411. The water separated by centrifugal force is discharged from the through hole 421, and the water on the voice coil motor is spun off by centrifugal force.

[0055] Step S5, after the centrifugal spin-drying is completed, the transfer mechanism 600 picks up the material frame 700 above the centrifugal spin-drying mechanism 400 and transfers it into the drying cavity 511 in the drying and dehumidifying mechanism 500. The second driving mechanism 540 drives the box cover 530 to close the drying cavity 511, and the heater 560 and the air blower 570 are used to deliver gas to the drying inner cavity to dry the residual water on the workpiece by drying and dehumidifying.

[0056] Step S6, the transfer trolley 900 is pushed into the unloading area 120 from the unloading port 121, and the transfer mechanism 600 picks up the material frame 700 and places it on the transfer trolley 900, so that the cleaned voice coil motor can be transferred out of the shell 100 to complete the unloading.

[0057] The above voice coil motor online cleaning equipment and cleaning process: first, the various functions required for cleaning the voice coil motor are integrated on one device according to the transmission sequence. From the feeding to the unloading process, the workpiece is cleaned by the first cleaning mechanism 200 to remove dust, and then transferred to the second cleaning mechanism 300 on one side for pure water bubble cleaning, which further rinses the workpiece more thoroughly. After completion, the workpiece is transferred to the centrifugal spin-drying mechanism 400 for dehydration treatment, and finally the surface of the workpiece is dried by the drying and dehumidifying mechanism 500. This eliminates the need for multiple single-machine devices to complete the cleaning process, saving manpower and processing time, reducing the occupied area, and making the processing site more clean and orderly. Second, after the voice coil motor is cleaned and placed on the second hollow support 340 in the second cleaning tank 311, the lifting mechanism 350 is started to drive the second hollow support 340 to move back and forth along the height direction of the second cleaning tank 311, which can clean more thoroughly and help improve the cleaning yield of the voice coil motor. Third, in the entire cleaning process, the transfer mechanism 600 transfers the workpiece automatically, and through automatic control, the workpiece can be cleaned twice, centrifugally dehydrated, and the surface is dried, which has high automation. Moreover, in the entire cleaning process, the transmission of the workpiece is always carried out in the shell 100, which greatly reduces the probability of secondary pollution of the workpiece compared with the traditional process of transferring between devices.

[0058] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure, direct or indirect application in other related technical fields, made by using the content of the present application specification and drawings, are also within the patent protection scope of the present application.
