Description

Technical Field

[0001] This invention belongs to the field of capacitor assembly, specifically an automated bushing device for capacitor assembly. Background Technology

[0002] According to the patent document with authorization announcement number "CN212277030U" and invention title "A Sleeving Machine for Aluminum Electrolytic Capacitors", the description states: Unsleeved capacitors are installed on an assembly mold with their bottoms facing upwards; the installation position is also the feeding position. A turntable drives the capacitor to rotate, and a sleeve device, via a sleeve conveying mechanism, installs vertical plastic sleeves around the capacitor and cuts the sleeves at a set height. A diaphragm assembly device then uses a suction cup to remove plastic diaphragms from a diaphragm flat conveyor and inserts them into the bottom of the capacitor. Finally, a laser marking device uses a laser probe to mark the bottom of the plastic diaphragm. Printing batch numbers, production dates, and other production information facilitates traceability of capacitor products. After passing through a preheating and shrinking device, the hot air chamber covers the bottom of the capacitor, performing the first heat shrinking treatment on the bottom of the sleeve to ensure it adheres to the bottom of the plastic film and prevents the film from detaching. Next, a flipping device grips the capacitor, and a turning mechanism flips it to its right side and places it on the conveyor belt of the heat shrink machine. The heat shrink machine body then secures the head of the sleeve and enhances the overall heat shrinking effect. Finally, the finished product is collected at the exit of the heat shrink machine. However, the following defects still exist:

[0003] When installing capacitor sleeves, the sleeve is moved downwards using a sleeve-installing device so that it fits over the outside of the capacitor. However, when pressing down, the sleeve and capacitor may not fit properly, thus affecting the effectiveness of the capacitor sleeve installation. Summary of the Invention

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figures 1-8 The present invention includes a workbench 1, a sleeve device 2 installed on the top of the workbench 1, a contact 4 installed on the top of the workbench 1, the bottom middle of the contact 4 being fixedly connected to the output shaft of a drive motor, the drive motor being installed on the workbench 1, the contact 4 being installed at equal angles on the outer wall of the contact 4, and a capacitor fixing assembly 5 being installed at equal angles on the top of the capacitor placement disk 3, the contact 4 being adapted to the capacitor fixing assembly 5.

[0032] The capacitor fixing assembly 5 includes a support platform 501 positioned at equal angles above the capacitor placement tray 3. A base plate 502 is located below the support platform 501 and is mounted on the top of the capacitor placement tray 3. A support rod 503 is mounted at equal angles on the top of the base plate 502, and its top is fixedly connected to the bottom of the support platform 501. A sliding groove 504 is formed at equal angles inside the support platform 501. A top groove 505 is formed at the top of the sliding groove 504, and a bottom groove 506 is formed at the bottom of the sliding groove 504. The sliding groove 504 is slidably mounted inside... A slider 507 is mounted, with a clamping plate 508 installed at its top. The clamping plate 508 is slidably connected to the top groove 505. A bottom plate 509 is installed at the bottom of the slider 507 and is slidably installed inside the bottom groove 506. A movable groove 512 is opened inside the support platform 501. Each sliding groove 504 is equally angled on the outside of the movable groove 512. The top of the movable groove 512 extends to the top of the support platform 501. The bottom groove 506 is connected to the movable groove 512. A movable plate 5 is movably installed inside the movable groove 512. 13. A capacitor-driven assembly 6 is installed at the top of the movable plate 513. A rotating rod 510 is provided at equal angles on the outer side of the movable groove 512. The rotating rod 510 is located inside the bottom groove 506. Rotary seats 511 are symmetrically installed at both ends of the rotating rod 510. One rotary seat 511 is fixedly installed on the bottom plate 509, and the other rotary seat 511 is fixedly installed on the outer wall of the movable plate 513. A screw 514 is threaded onto the movable plate 513. The bottom end of the screw 514 is fixedly connected to the output shaft of the servo motor 515. 5 is fixedly installed at the bottom of the support platform 501. After the servo motor 515 is turned on, it drives the screw 514 to rotate. The movable plate 513 is threadedly connected to the screw 514, thereby driving the movable plate 513 to move upward along the movable groove 512. Since the movable plate 513 has a rotating rod 510 rotatably installed on its outer side, and the rotating rod 510 is rotatably connected to the bottom plate 509, and the bottom plate 509 can only move laterally, it drives each clamping plate 508 to move towards the capacitor, clamping the capacitor, thereby improving the stability of the capacitor sleeve and improving the sleeve effect.

[0033] The capacitor-driven assembly 6 includes a push plate 602 disposed inside the movable groove 512. The outer wall of the push plate 602 contacts the inner wall of the movable groove 512. The push plate 602 is located above the movable plate 513. A fixed cylinder 605 is symmetrically installed at the top of the movable plate 513. A movable block 606 is movably installed inside the fixed cylinder 605. A push rod 607 is installed at the top of the movable block 606. A limiting rotating ring 610 is installed at the top of the push rod 607. The limiting rotating ring 610 is annular and rotatably installed inside a limiting ring groove 609. The limiting ring groove 609 is formed in the push plate 602. Inside 2, a first spring 608 is installed at the bottom of the movable block 606. The bottom of the first spring 608 is fixedly connected to the inner bottom wall of the fixed cylinder 605. An annular groove 603 is provided on the outer side of the push plate 602. A fixed block 601 is installed at equal angles on the inner wall of the movable groove 512. The upper and lower sides of the fixed block 601 are in contact with the upper top wall and lower bottom wall of the annular groove 603, respectively. A through groove 604 is provided at equal angles at the top and bottom of the annular groove 603. The top wall of the push plate 602 is on the same plane as the top wall of the support platform 501. A push plate rotating assembly 7 is installed at the bottom of the push plate 602.

[0034] The push plate rotating assembly 7 includes an end rod 701 mounted on the top of the screw 514. The end rod 701 has a rod groove 702 inside, with the top of the groove 702 extending through to the top of the end rod 701. Guide grooves 703 are symmetrically formed on both sides of the inner wall of the rod groove 702. A first bottom rod 706 is provided inside the rod groove 702, with its top fixedly connected to the bottom of the push plate 602. The outer wall of the first bottom rod 706 is in close contact with the inner wall of the rod groove 702. A movable sleeve 704 is provided below the first bottom rod 706, with its outer wall in close contact with the inner wall of the rod groove 702. Guide blocks 705 are symmetrically mounted on both sides of the movable sleeve 704, and the guide blocks 705 are slidably connected to the guide grooves 703. A second guide block 705 is mounted at the bottom of the first bottom rod 706. The bottom rod 707 and the second bottom rod 707 are inserted into the interior of the movable sleeve 704. A torsion spring 708 is installed between the inner wall of the movable sleeve 704 and the outer wall of the second bottom rod 707. A push plate snap-fit ​​assembly 8 is installed between the push plate 602 and the movable groove 512. After the screw 514 rotates, it drives the movable sleeve 704 to rotate, while the first bottom rod 706 at the bottom end of the push plate 602 is fixed, so that the movable sleeve 704 and the second bottom rod 707 rotate relative to each other, thereby compressing the torsion spring 708. After the push plate 602 disengages from the snap-fit, the push plate 602 rotates under the elastic force of the torsion spring 708, so that the through groove 604 rotates to the position corresponding to the fixed block 601, so that the push plate 602 has an upward movement margin, which facilitates the upward pushing force on the capacitor and improves the sleeve effect.

[0035] The push plate latching assembly 8 includes a latching groove 801 formed on one side of the push plate 602. A movable groove 802 is formed on the inner wall of the movable groove 512. The axis of the movable groove 802 is on the same plane as the axis of the latching groove 801. A movable block 803 is movably installed inside the movable groove 802. A latching rod 804 is installed on the side of the movable block 803 closest to the interior of the movable groove 512, and the latching rod 804 latches into the interior of the latching groove 801. A second spring 805 is installed on the side of the movable block 803 away from the latching rod 804, and one end of the second spring 805 is fixedly connected to the inner wall of the movable groove 802. A magnetic block 806 is installed on the side of the movable block 803 away from the latching rod 804. An electromagnet 807 is provided on the side of the magnetic block 806 away from the latch 804. The electromagnet 807 is fixedly installed on the inner wall of the movable groove 802 away from the movable groove 512. The electromagnet 807 is electrically connected to the contact 4. After the movable plate 513 moves upward, the push plate 602 is latched, which causes the fixed cylinder 605 to move upward relative to the top rod 607, causing the first spring 608 to be compressed. After the push plate 602 is disengaged from the fixed block 601 and the latch 804, the push plate 602 generates an upward pushing force on the bottom end of the capacitor under the elastic force of the first spring 608, which facilitates the capacitor to fully enter the sleeve, thereby further improving the sleeve effect.

[0036] Working principle: When in use, place the capacitors that need to be sleeved on each support platform 501, turn on the drive motor to make the capacitor placement disk 3 rotate. When one of the support platforms 501 rotates to the bottom of the sleeve device 2, the drive motor is de-energized and the sleeve device 2 starts working to sleeve the capacitor.

[0037] When the support platform 501 moves to the bottom of the sleeve device 2, the servo motor 515 is turned on, causing the screw 514 to rotate. Since the movable plate 513 is threadedly connected to the screw 514, and the movable plate 513 is limited by the rotating rod 510 and the bottom groove 506, the movable plate 513 moves upward. After the movable plate 513 moves upward, under the action of the rotating rod 510, it pulls each clamping plate 508 toward the capacitor, so that each clamping plate 508 clamps and fixes the capacitor, which facilitates the sleeve of the capacitor.

[0038] When the capacitor placement disk 3 rotates, the contact 4 corresponding to the capacitor fixing component 5 that moves to the bottom of the sleeve device 2 is energized. During the sleeve process, the sleeve device 2 drives the sleeve to move downward and fit on the outside of the capacitor. During the upward movement of the movable plate 513, the push plate 602 is locked and fixed, which causes the movable plate 513 to move upward and the distance between the movable plate 513 and the push plate 602 to become closer. This causes the fixed cylinder 605 to move upward relative to the top rod 607, which compresses the first spring 608. At the same time, when the screw 514 rotates, the guide block 705 on the movable sleeve 704 is slidably connected to the rod groove 702, which causes the movable sleeve 704 to rotate with the screw 514. The second bottom rod 707 is fixed, which causes the movable sleeve 704 and the second bottom rod 707 to rotate relative to each other, which compresses the torsion spring 708.

[0039] When the sleeve is installed, the electromagnet 807 is energized and attracts the magnetic block 806, thereby driving the locking rod 804 into the interior of the moving groove 802. This causes the locking rod 804 to disengage from the groove 801, and under the elastic force of the torsion spring 708, the push plate 602 is rotated to the position corresponding to the fixed block 601 and the through groove 604. This allows the push plate 602 to have an upward movement margin, which facilitates the upward pressure on the capacitor.

[0040] At the same time, the push plate 602 disengages from the fixing block 601 and the locking rod 804, allowing the push plate 602 to move upward. Due to the compression of the first spring 608, when the sleeve is in place, the push plate 602 exerts an upward pushing force on the capacitor under the elastic force of the first spring 608, thereby improving the sleeve connection effect between the capacitor and the sleeve.
