Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 16, an impregnation device 10 according to the present invention will now be described. The impregnation device 10 provided by the embodiment of the invention is used for impregnating the capacitor core package 20. Specifically, an impregnation device 10 includes: the impregnation cylinder 100, the first conveying mechanism 200, the conveying mechanism 300 and the pressure mechanism 400. The impregnation cylinder 100 has a first cavity and an impregnation chamber 110 received in the first cavity. The impregnation cylinder 100 includes an outer cylinder 120 and a first drive assembly 130. The outer cylinder 120 includes a first casing 121 and a second casing 122 that are opened and closed. The first driving assembly 130 is used for controlling the first casing 121 and the second casing 122 to open and close along a first direction. The first cavity is formed by closing the first case 121 and the second case 122. In this embodiment, the first direction is parallel to the direction indicated by the arrow X in fig. 1.

Further, the first conveying mechanism 200 is used for conveying the capacitor core package 20 between the first casing 121 and the second casing 122 so as to be received by the impregnation chamber 110. The impregnation chamber 110 matches the distribution of the capacitor core package 20 between the first case 121 and the second case 122. The conveying mechanism 300 is used for controlling the electrolyte to enter and exit the impregnation chamber 110. Since the size of the impregnation chamber 110 is related to the distribution of the capacitor core package 20, the space for storing the electrolyte, that is, the volume of the impregnation chamber 110 can be reduced when the impregnation process is satisfied, the utilization rate of the electrolyte is improved, and the time for controlling the electrolyte to enter and exit the impregnation chamber 110 by the conveying mechanism 300 is shortened due to the small volume of the impregnation chamber 110, thereby improving the production efficiency of the capacitor. When the electrolyte needs to be replaced, the electrolyte source connected to the conveying mechanism 300 may be replaced. The pressure mechanism 400 is used to vary the pressure within the impregnation chamber 110. The first transfer mechanism 200 transfers the capacitor core pack 20 between the first case 121 and the second case 122. The first driving assembly 130 controls the first casing 121 and the second casing 122 to close along the first direction, so that the capacitor core package 20 is located in the first cavity to be accommodated in the impregnation chamber 110, and then the conveying mechanism 300 introduces the electrolyte into the impregnation chamber 110, and the pressure mechanism 400 pressurizes the first cavity to perform impregnation. After impregnation is completed, the conveying mechanism 300 withdraws the electrolyte in the impregnation chamber 110, and the first chamber is depressurized by the pressure mechanism 400. The first driving assembly 130 controls the first and

second housings

121 and 122 to be opened in the first direction. The first conveying mechanism 200 removes the capacitor core package 20 and conveys another capacitor core package 20 to a position between the first casing 121 and the second casing 122 for an impregnation process.

So that the clamping process and the unclamping process are smoother. The latch 800 may be driven by the first cylinder 840 or a plurality of first cylinders 840 simultaneously driven by one first cylinder 840 to move in a direction perpendicular to the first direction to clamp the closed first and

second housings

121 and 122. In this embodiment, the lock catch 800 includes eight lock catches, and two lock catches are oppositely disposed above and below the outer cylinder 120.

The output end of the first driving unit 131 is hinged to the first hinge point 1321. The fixing block 135 is hinged to the fourth hinge point 1324. The first driving unit 131 can drive the first driving block 132 to rotate about the fourth hinge point 1324. The two ends of the first link 133 are respectively hinged to the second hinge point 1322 and the first housing 121. The first link 133 can drive the first housing 121 to move in the first direction by rotating with the first driving block 132. Specifically, the first link 133 is hinged to the motor base 550 by a first ear plate 551. The second link 134 is hinged at two ends to the third hinge point 1323 and the second housing 122, respectively.

The counting device is used for recording the number of the capacitor core packages 20 entering the clip group between the first casing 121 and the second casing 122 so as to control the position of the electrolyte level in the impregnation chamber 110 relative to the capacitor core packages 20. This can be achieved by controlling the amount of electrolyte added or by varying the elevation of the inner cylinder 140. In this embodiment, the position of the electrolyte level in the impregnation chamber 110 relative to the capacitor core package 20 is controlled by changing the elevation height of the inner cylinder 140. When the number of the capacitor core packages 20 is less than the set value, the electrolyte level meets the impregnation process by raising the inner cylinder 140, so that the capacitor core packages 20 can be impregnated.
