A partition is fixedly installed inside the bottom of the movable cover, and a glue outlet head is provided on the partition at a position corresponding to the placement slot.

A connecting groove is opened on the top of the side wall of the movable cover, and the position of the connecting groove is higher than the partition, and the tail end of the connecting pipe is fixedly connected to the connecting groove.

[0012] As a further solution of the present invention, a group of guide plates are fixedly installed on the left side of the top of the base, and the guide plates are located on both sides of the conveyor belt.

[0013] A film capacitor epoxy resin primary packaging production device, comprising the following steps:

[0014] S1: First, place the capacitor to be packaged with the opening facing upward into the placement slot, then place the placement tray onto the conveyor belt, then pour the prepared epoxy resin into the storage barrel, and then cover the top of the storage barrel with the barrel lid.

[0015] S2: Start the drive motor, and drive the conveyor belt through the drive motor. The conveyor belt drives the placement plate to the bottom of the movable cover, and the side of the placement plate will be stuck in the groove of the rotating plate. Then start the control motor to control the telescopic rod to move down to cover the movable cover on the placement plate. In the process of the card block on the movable cover being stuck in the card slot, since the tops of both sides are arc-shaped, the card block will push the card slot to rotate automatically and adjust to the locking angle, thereby driving the placement plate to rotate, and aligning the placement slot on the placement plate with the glue discharge head.

[0016] S3: When the movable cover is placed on the placement tray, the vacuum pump will start, and the air between the placement tray and the movable cover will be extracted through the vacuum pipe on the vacuum pump. Since the air pressure between the placement tray and the movable cover drops rapidly, the external atmospheric pressure will press the epoxy resin in the storage barrel to be transported to the inside of the movable cover through the connecting pipe, and then evenly squeezed into the capacitor in the placement slot through the glue outlet head. Then the vacuum pump is turned off, and the air enters the placement tray and the movable cover. After the air pressure is restored, the telescopic rod is started to lift the movable cover from the placement tray.

[0017] S4: When the movable cover moves down, the rack drives the gear ring to rotate clockwise, and the inner and outer sides of the one-way shaft will not get stuck. When the movable cover moves up, the rack drives the gear ring to rotate counterclockwise. At this time, the inner and outer circles of the one-way shaft will get stuck, and the gear ring will drive the one-way shaft to rotate. The one-way shaft will drive the first gear to rotate through the connecting rod, and the engagement of the first gear and the second gear can drive the linkage column to rotate. Since the rotating ring at the bottom of the linkage column is connected to the rotating column by a connecting belt, the linkage column can drive the rotating column to rotate when the rotating ring is driven to rotate. The rotating column will control the rotation of the rotating disk to move the placement disk on the left to the right.

[0018] S5: The placement tray filled with epoxy resin is driven by a conveyor belt to pass through the bottom of the UV lamp cover. When passing under the UV lamp cover, the UV light in the UV lamp cover can quickly solidify the surface of the epoxy resin in the capacitor, and the epoxy resin flows when placed and moved.

[0019] S6: Collect the trays and move them to the curing equipment to completely cure the epoxy resin in the capacitor, saving a lot of time and energy.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the active cover, the rotating disk, the one-way shaft, the gear ring, the rack, the telescopic rod, the vacuum pump, the vacuum pipe, and the glue discharge head cooperate with each other to automatically fill the epoxy resin into the capacitor on the placement disk. After filling, the placement disk will be automatically moved to the other side for the next process, which is very convenient and effectively improves the packaging efficiency.

[0022] 2. In the present invention, the placement tray filled with epoxy resin is driven by a conveyor belt to pass through the bottom of the ultraviolet lamp cover. When passing under the ultraviolet lamp cover, the ultraviolet light in the ultraviolet lamp cover can quickly cure the surface of the epoxy resin in the capacitor. Then the placement trays are collected and moved to the curing equipment to completely cure the epoxy resin in the capacitor, thereby saving a lot of time, improving production efficiency, and saving energy.

[0039] A film capacitor epoxy resin primary packaging production device, comprising the following steps:

[0040] S1: First, place the capacitor to be packaged with its opening facing upward into the placement groove 33, then place the placement plate 6 onto the conveyor belt 3, then pour the prepared epoxy resin into the storage barrel 11, and then cover the top of the storage barrel 11 with the barrel cover 12.

[0041] S2: Start the driving motor 4, and drive the conveyor belt 3 through the driving motor 4. The conveyor belt 3 drives the placement plate 6 to the bottom of the movable cover 9, and the side of the placement plate 6 will be stuck in the groove of the rotating plate 17. Then start the control motor 8 to control the telescopic rod 30 to move down to cover the movable cover 9 on the placement plate 6.

[0042] S3: When the movable cover 9 is placed on the placement tray 6, the vacuum pump 31 will be started, and the air between the placement tray 6 and the movable cover 9 will be extracted through the vacuum pipe 34 on the vacuum pump 31. Since the air pressure between the placement tray 6 and the movable cover 9 drops rapidly, the external atmospheric pressure will press the epoxy resin in the storage barrel 11 to be transported to the inside of the movable cover 9 through the connecting pipe 14, and then evenly squeezed into the capacitor in the placement groove 33 through the glue outlet head 35.

The one-way shaft 20 will drive the first gear 23 to rotate through the connecting rod 22, and the engagement of the first gear 23 and the second gear 25 can drive the linkage column 24 to rotate. Since the rotating ring 26 at the bottom of the linkage column 24 is connected to the rotating column 27 by the connecting belt 28, when the linkage column 24 drives the rotating ring 26 to rotate, it can also drive the rotating column 27 to rotate. The rotating column 27 will control the rotating disk 17 to rotate and move the placement disk 6 on the left to the right.

[0044] S5: The placing tray 6 filled with epoxy resin is driven by the conveyor belt 3 to pass through the bottom of the ultraviolet lamp cover 18. When passing under the ultraviolet lamp cover 18, the ultraviolet light in the ultraviolet lamp cover 18 can quickly solidify the surface of the epoxy resin in the capacitor, and the epoxy resin flows when placed and moved.
