Description

Technical Field

[0001] This invention relates to the field of capacitor magnetic sheet production equipment technology, and in particular to a fully automatic magnetic sheet roller coating and drying integrated machine and a magnetic sheet coating method. Background Technology

[0002] A magnetic sheet is a square magnetic conductor, a common electronic component in electronic capacitors, and typically requires multiple layers of magnetic sheets stacked together. During the production process, a layer of paste is applied to the outer side surface of the magnetic sheet. The top and bottom surfaces do not require dipping. After coating the outer side surface, it needs to be dried to fully evaporate the moisture from the outer layer of paste, forming a paste layer on the side of the magnetic sheet. Traditional magnetic sheet processing involves manually brushing the paste onto the outer side surface of the magnetic sheet, followed by placing it in a dry environment or drying equipment for drying. Manual application of paste during production can easily lead to uneven coating. Transferring the coated magnetic sheet to the dry environment or drying equipment takes time, affecting production efficiency. Furthermore, during the drying process, undried paste will sink downwards due to gravity, resulting in uneven paste layer thickness in the final product, severely impacting the quality of the finished product.

[0012] This invention also discloses a magnetic sheet coating method using the aforementioned integrated machine, which includes the following steps:

[0013] S1. Place the receiving tray containing the magnetic sheet on the storage rack. The lifting mechanism raises the receiving tray to the height corresponding to the translation mechanism. The receiving tray is hooked into the translation mechanism by the hooking component and then conveyed to the end of the translation mechanism near the vibrating feeding mechanism.

[0014] S2. The loading robot moves to the top of the corresponding receiving tray, the electric gripper starts and picks up a certain number of magnetic sheets. At this time, the rotary motor starts and drives the electric gripper to rotate until the tilt angle of the magnetic sheet is consistent with the tilt angle of the loading groove. Then the magnetic sheet is placed into the loading groove. The pushing motor drives the pushing block to push the magnetic sheet to the highest position of the loading groove. During the process, the vibration motor vibrates continuously to make the magnetic sheet fit the loading groove.

[0015] S3. When the position sensor detects that the magnetic sheet is in place, the transfer robot moves the magnetic sheet to the coating device. The locking motor pushes the locking slider to move, so that the second rotary suction head separates from the rotary suction head. The rotary cylinder then drives the locking swing arm to rotate upward to make room for the magnetic sheet. After the transfer robot moves the magnetic sheet into place, the locking component resets. The rotary suction head and the second rotary suction head are vacuumed to attract the magnetic sheet, and the magnetic sheet is rotated under the drive of the second motor.

[0016] S4. The circulation pump starts and pumps the slurry stored in the mixing tank into the impregnation box. At this time, the first motor drives the auxiliary coating wheel to rotate. At the same time, the coating roller moves downward under the drive of the coating cylinder to the position tangent to the auxiliary coating wheel. The auxiliary coating wheel rolls the slurry onto the coating roller and fills the oblique groove. Then, the coating cylinder drives the coating roller to move upward to the position in contact with the magnetic sheet and coats the outer surface of the side of the magnetic sheet.

[0017] S5. The material transfer robot transfers the coated magnetic sheet to the rotating suction head. At this time, the feeding drive cylinder starts and presses the trigger valve corresponding to the rotating suction head. The rotating suction head is vacuumed to attract the magnetic sheet. The revolution motor drives the rotating disk to rotate and enters the rotating suction head with the attracted magnetic sheet into the drying chamber from the feed port. The dryer starts and injects hot air into the drying chamber. During the process, the rotating motor starts and drives the rotating suction head to rotate through the synchronous belt to prevent the slurry from settling on the magnetic sheet.

[0018] S6. After the rotating suction head with the magnetic sheet adsorbed revolves once under the drive of the rotating disk, it leaves the drying chamber from the discharge port. The rotating guide wheel on the rotating suction head disengages from the synchronous belt, the rotating suction head stops rotating, and the rotating disk also stops revolving. The unloading robot arm adsorbs the magnetic sheet, and at the same time, the unloading drive cylinder starts, presses the trigger air valve corresponding to the rotating suction head, releases the vacuum, and the magnetic sheet is detached from the rotating suction head under the drive of the unloading robot arm.

[0019] S7. The suction robot transfers the dried magnetic sheet to the industrial camera, which takes pictures and compares information such as the appearance, coating, and rotation angle of the magnetic sheet. Finally, the magnetic sheet with the coating dried is rotated to the angle that meets the storage requirements of the receiving tray and then placed into the receiving tray to complete the magnetic sheet processing.

[0020] S8. After the receiving tray is full, the double-layer conveyor will transport the controlled receiving tray to the recycling position, and at the same time return the full receiving tray to the corresponding position in the receiving tray storage area, where the magnetic sheets on the receiving tray will be removed manually.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a rotary drying device to convey the magnetic sheet after slurry coating to the drying chamber, simultaneously performing both rotary and eccentric movements at a uniform speed. This ensures that the slurry coated on the outer surface of the magnetic sheet does not settle due to gravity during the high-temperature drying process, preventing uneven coating on the magnetic sheet surface and ensuring the production quality of the magnetic sheet. Furthermore, the proportional valve adjusts the output of the coating cylinder and the second motor in real time, thereby controlling the rotation speed of the rotating suction head and the contact pressure between the coating roller and the magnetic sheet. This ensures that the square-structured magnetic sheet makes hard contact with the coating roller at its four corners during rotation, preventing damage to the coating roller. Therefore, the present invention achieves high slurry coating quality, high production efficiency, and uniform slurry layer thickness. Attached Figure Description

[0042] This invention also discloses a magnetic sheet coating method for the above-mentioned all-in-one machine, comprising the following steps:

[0043] S1. Place the receiving tray containing the magnetic sheet on the storage rack 124. The lifting mechanism 12 lifts the receiving tray to the height corresponding to the translation mechanism 13. The receiving tray is hooked into the translation mechanism 13 by the hooking component and then conveyed to one end of the translation mechanism 13 near the vibrating feeding mechanism 14.

[0044] S2. The loading robot 15 moves to the top of the corresponding receiving tray, the electric gripper 155 starts and picks up a certain number of magnetic sheets. At this time, the rotary motor 154 starts and drives the electric gripper 155 to rotate until the tilt angle of the magnetic sheet is consistent with the tilt angle of the loading groove 144. Then, the magnetic sheet is placed into the loading groove 144. The pushing motor 145 drives the pushing block 146 to push the magnetic sheet to the highest position of the loading groove 144. During the process, the vibration motor 143 continuously vibrates to make the magnetic sheet fit the loading groove 144.

[0045] S3. When the position sensor 147 detects that the magnetic sheet is in place, the transfer robot 5 transfers the magnetic sheet to the coating device 2. The locking motor pushes the locking slider 26 to move, causing the second rotary suction head 29 to separate from the rotary suction head 244. The rotary cylinder 27 then drives the locking swing arm 28 to rotate upward to make room for the magnetic sheet. After the transfer robot 5 moves the magnetic sheet into place, the locking component is reset. The rotary suction head 244 and the second rotary suction head 29 are vacuumed to attract the magnetic sheet, and the magnetic sheet is rotated under the drive of the second motor 243.

[0046] S4. The circulating pump 21 is started, pumping the slurry stored in the mixing tank 22 into the impregnation box 23. At this time, the first motor 241 drives the auxiliary coating wheel 242 to rotate. At the same time, the coating roller 247 moves downward under the drive of the coating cylinder 246 to the position tangent to the auxiliary coating wheel 242. The auxiliary coating wheel 242 rolls the slurry onto the coating roller 247 and fills the oblique cut groove 200. Then, the coating cylinder 246 drives the coating roller 247 to move upward to the position in contact with the magnetic sheet, and coats the outer surface of the side of the magnetic sheet.

[0047] S5. The material transfer robot 5 transfers the coated magnetic sheet to the rotating suction head. At this time, the feeding drive cylinder 303 starts and presses the trigger valve 302 corresponding to the rotating suction head. The rotating suction head draws a vacuum to attract the magnetic sheet. The revolution motor 30 drives the rotating disk 31 to rotate and enters the drying chamber from the feed port 305 with the magnetic sheet attracted. The dryer 301 starts and injects hot air into the drying chamber. During the process, the rotating motor 36 starts and drives the rotating suction head to rotate through the synchronous belt 38 to prevent the slurry from settling on the magnetic sheet.

[0048] S6. After the rotating suction head with the magnetic sheet adsorbed revolves once under the drive of the rotating disk 31, it leaves the drying chamber from the discharge port 306. The rotating guide wheel 34 on the rotating suction head disengages from the synchronous belt 38, the rotating suction head stops rotating, and the rotating disk 31 also stops revolving.
