DETAILED DESCRIPTION

The loading area 110 is connected to the loading port 111, and the unloading area 120 is connected to the unloading port 121. In the housing 100, the workpiece to be cleaned (i.e., the voice coil motor) can be loaded, cleaned twice, centrifugally dehydrated, and dried in sequence, and finally unloaded to the unloading area 120. The various processes required in the workpiece cleaning process are all integrated into one device, and the various processes can be processed in sequence and orderly, and the number of single machines is reduced, thereby saving labor and cleaning time; multiple devices are no longer needed, so the floor space can be reduced, making the production and assembly site tidier, and the transmission of the voice coil motor to each process is completed by the transfer mechanism 600 in the shell 100, which can also reduce the secondary contamination of the workpiece during the transmission process.

[0041] The voice coil motor online cleaning equipment also includes a material receiving frame 700 and at least one supporting fixture 800 that can be accommodated in the material receiving frame 700 for supporting the voice coil motor. The side walls of the material receiving frame 700 are all distributed with a through opening 710, wherein two through openings 710 arranged opposite to each other can cooperate with the transfer mechanism 600, and the transfer mechanism 600 is used to realize the transfer of the material receiving frame 700. In addition, the side walls of the material receiving frame 700 are distributed with a plurality of side wall through holes 720 located below the through openings 710. When the supporting fixture 800 carrying the workpiece is placed in the material receiving frame 700 and enters each process for processing, the side wall openings and the through openings 710 are connected to the inside to avoid interference with the processing of each process.

[0042] See also Figure 4 The supporting fixture 800 includes a supporting seat 810 and a plurality of supporting plates 820 detachably connected to the supporting seat 810 for supporting the voice coil motor. Figure 6The first end surface of the carrier plate 820 is provided with a plurality of bearing grooves 821 arranged at intervals and adapted to the shape of the voice coil motor and used to bear the voice coil motor, and each bearing groove 821 is provided with a through hole 8210 penetrating in a direction away from the first end surface. After the voice coil motor is loaded in the loading groove, the through hole 8210 increases the exposed area of ​​the voice coil motor, which is convenient for each process to handle the workpiece accordingly.

[0043] See also Figure 4 and Figure 5 The support seat 810 includes two support plates 811 arranged at intervals, and a limiting structure connected to the support plates 811 and provided with a limiting structure for limiting the bearing plate 820.

The positions of the limiting rod 812A in the first limiting assembly 812 and the limiting rod 812A in the second limiting assembly 813 correspond one to one, and the outer diameter of the limiting protrusion 812B is larger than the outer diameter of the limiting rod 812A. Therefore, the limiting structure will form four limiting spaces, and the corners of the supporting plate 820 are inserted into the limiting spaces. Multiple supporting plates 820 carrying voice coil motors can be limited at the same horizontal position. Multiple workpieces can be processed at the same time in one batch, and cleaning is more efficient.

[0044] A through channel 830 is provided at the end position of each limiting rod 812A on the support plate 811 for the limiting rod 812A to pass through. The through channel 830 includes a horizontal cavity and a vertical cavity connected to the horizontal cavity. The horizontal cavity and the vertical cavity are connected to form an L-shaped through channel 830. Since the horizontal cavity is arranged along the width direction of the support plate 811, and the vertical cavity is arranged along the height direction of the support plate 811, and the vertical cavity is connected to the side of the horizontal cavity close to the outside of the support plate 811, the vertical cavity is closer to the outer wall of the support plate 811. When the limiting rod 812A is fixed to the support plate 811, the vertical cavity is connected to the side of the horizontal cavity close to the outside of the support plate 811. When the support plate 820 is raised, the two ends of the limit rod 812A are extended from the horizontal cavity, and each end of the limit rod 812A is screwed with a locking nut 840 for locking the position of the limit rod 812A passing through the through channel 830. The locking nut 840 is screwed to the part of the limit rod 812A extending out of the horizontal cavity and locks the position of the limit rod 812A. When the support plate 820 needs to be taken out, the locking nut 840 is loosened and the limit rod 812A is moved into the vertical cavity, which is equivalent to moving the limit rod 812A toward the outside of the support plate 811, so that the support plate 820 limited in the limiting space can be separated from the limiting structure.

The same support seat 810 can fix several spaced bearing plates 820 through the limiting space, and the carrying jig 800 is placed on the transfer cart 900, and pushed into the loading area 110 corresponding to the position of the loading port 111 of the housing 100.

[0054] Step S2, the transfer mechanism 600 picks up the material frame 700 in the loading area 110 and transfers it to the top of the first cleaning mechanism 200, and then puts the material frame 700 and the supporting fixture 800 carrying the workpiece in the material frame 700 into the first cleaning mechanism 200, and performs dust removal and cleaning on the voice coil motor by vibration bubbling.

[0055] In the above step S2, the transfer mechanism 600 can be moved to the loading area 110 along the arrangement direction of the upper guide rod 611 and the lower guide rod 612 through automatic control, and is located above the material receiving frame 700. The picking part 620 that can move along the lifting guide rail 614 can extend into the material receiving frame 700. After starting the driving unit 622, the two support plates 623A are horizontally unfolded along the picking seat 621, so that the picking hook 623B extends into the through opening 710 and hooks the through opening 710. The movement of the sliding table 613 can transfer the material receiving frame 700 to the first cleaning tank 230 and prevent it from being on the first hollow bracket 250. The vibrator 210 under the first cleaning box 220 is started to vibrate the first cleaning box 220 at a fixed frequency. The pure water in the first cleaning tank 230 can be heated by the first heating tube 260, and during the vibration cleaning process, the first air hole 240 allows air to flow into the first cleaning tank 230 to make the pure water bubble. The workpiece in the first cleaning tank 230 is subjected to bubbling and vibration to achieve the purpose of dust removal.

[0056] Step S3, after the cleaning in the first cleaning mechanism 200 is completed, the transfer mechanism 600 picks up the material frame 700 above the first cleaning mechanism 200 and transfers it to the second cleaning mechanism 300, and then puts the material frame 700 into the second hollow bracket 340 in the second cleaning mechanism 300, and the lifting drive motor 355 in the lifting mechanism 350 is started, and the moving rod 351B can move up and down in the guide block 351A, so that the second hollow bracket 340 carrying the material frame 700 can be lifted and moved in the pure water of the second cleaning tank 311, and the same bubbling function as mentioned above is added to further perform a more detailed pure water rinse on the workpiece.

[0057] Step S4, after the cleaning in the second cleaning mechanism 300 is completed, the transfer mechanism 600 picks up the material receiving frame 700 above the second cleaning mechanism 300 and transfers it to the top of the centrifugal drying mechanism 400, and then puts the material receiving frame 700 into the drying rack 420 of the centrifugal drying mechanism 400, and the rotating drive motor 432 drives the active wheel 433 to rotate, and the driven wheel 434 connected to the transmission belt 435 can also rotate horizontally, so that the drying rack 420 can rotate horizontally in the drying inner cavity 411, and the water separated by centrifugation is discharged from the through hole 421, and the water on the voice coil motor is dried by centrifugation.

[0058] Step S5, after the centrifugal drying is completed, the transfer mechanism 600 picks up the material receiving frame 700 above the centrifugal drying mechanism 400 and transfers it to the drying chamber 511 in the drying and dehumidification mechanism 500, and the second driving mechanism 540 drives the box cover 530 to close the drying chamber 511, and transports gas to the drying inner cavity through the heater 560 and the blower 570, and the moisture remaining after the workpiece is dried is dried by drying and dehumidification.

[0059] Step S6, push the transfer cart 900 into the unloading area 120 from the unloading port 121, and the transfer mechanism 600 picks up the receiving frame 700 and places it on the transfer cart 900, so that the cleaned voice coil motor can be transferred out of the housing 100 to complete the unloading.

[0060] The above-mentioned online cleaning equipment and cleaning process of the voice coil motor: First, various functions required for cleaning the voice coil motor are integrated into one device according to the transmission sequence. During the process of loading and unloading the workpiece, the workpiece is cleaned by the first cleaning mechanism 200 through vibration bubbling to remove dust from the workpiece, and then transferred to the second cleaning mechanism 300 on one side for pure water bubbling cleaning, and further rinsed more thoroughly. After completion, the workpiece is transferred to the centrifugal drying mechanism 400 for dehydration by rotating centrifugal method, and finally the surface of the workpiece is dried by the drying and dehumidification mechanism 500. It is no longer necessary to use multiple stand-alone equipment to complete the cleaning process, saving manpower and processing time, and reducing the floor space, making the processing site more tidy and orderly. Second, after the voice coil motor has been cleaned by dust removal, it is placed on the second hollow bracket 340 in the second cleaning tank 311, and the lifting mechanism 350 is started to drive the second hollow bracket 340 to move back and forth along the height direction of the second cleaning tank 311, so that the cleaning is more thorough, which helps to improve the cleaning yield of the voice coil motor. 3. In the whole cleaning process, the transfer mechanism 600 transfers the workpiece using automatic control, and can perform two cleanings, centrifugal dehydration and surface drying on the workpiece through automatic control, with a high degree of automation. In addition, during the whole cleaning process, the workpiece is always transferred within the housing 100, which greatly reduces the probability of secondary contamination of the workpiece compared to the traditional method of transferring between various devices.

Any equivalent structure made using the contents of the present invention's specification and drawings, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present invention.
