Description

Technical Field

[0001] This utility model generally relates to the field of capacitor technology, and specifically to a feeding device and an aluminum electrolytic capacitor sealing machine having the same. Background Technology

[0002] In the manufacturing process of aluminum electrolytic capacitors, a sealing machine is required to press the open end of the aluminum shell into the end cap. Existing sealing machines include a turntable, a sealing device, and a feeding device. The process is as follows: the capacitor to be sealed is placed on the turntable; the turntable rotates to transport the capacitor to the bottom of the sealing device, where it is sealed; then the turntable rotates again to transport the capacitor to the feeding device, which then removes the capacitor from the turntable. The feeding device typically includes two sets of robotic arms that work together to move the capacitor. However, the aforementioned feeding device suffers from complex structure and high cost. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a feeding device and an aluminum electrolytic capacitor sealing machine having the same.

[0004] In a first aspect, this application provides a feeding device, comprising:

[0005] Linear driver;

[0006] A pusher is connected to the drive end of a linear actuator and is movable in a first direction under the drive of the linear actuator. The pusher forms a limiting cavity. The limiting cavity has an opening on the side away from the linear actuator for the capacitor to enter and exit. The limiting cavity is used to limit the displacement of the capacitor located therein in a second direction. The first direction and the second direction are perpendicular. The size of the limiting cavity is adjustable.

[0007] Furthermore, the pusher includes a plurality of push parts arranged in sequence, and the plurality of push parts surround a limiting cavity. Any two adjacent push parts are connected by a connecting structure. The connecting structure has a locked state and an unlocked state. In the locked state, the two push parts connected by the connecting structure can rotate relative to each other to adjust the size of the limiting cavity. In the unlocked state, the positions of the two push parts connected by the connecting structure are relatively fixed.

[0008] Furthermore, an installation tube assembly is provided between any two adjacent push units. The installation tube assembly includes a first installation tube and a second installation tube respectively disposed in different push units. The first installation tube and the second installation tube are staggered along a third direction and their axes are parallel to the third direction. The third direction, the second direction and the first direction are perpendicular to each other. The connecting structure passes through the first installation tube and the second installation tube.

[0009] Furthermore, the connection structure includes a connecting bolt and a nut, the connecting bolt passing through the first mounting tube and the second mounting tube and screwed onto the nut, wherein at least one of the shank head of the connecting bolt and the nut is located on one side of two adjacent push portions along a third direction.

[0010] Furthermore, the promotion department is the promotion board.

[0011] Furthermore, the driving end of the linear actuator is connected to one of the connection structures.

[0012] Furthermore, the linear actuator can be a pneumatic cylinder, a hydraulic cylinder, or an electric actuator.

[0013] Secondly, this application also provides an aluminum electrolytic capacitor sealing machine, including the above-mentioned feeding device.

[0014] The feeding device and aluminum electrolytic capacitor sealing machine provided in this application are connected to a pusher via a linear actuator, which drives the pusher to move along a first direction. The pusher has a limiting cavity that can accommodate the capacitor and limit the displacement of the capacitor along a second direction, so that the capacitor can reliably complete the feeding process under the drive of the pusher. This not only simplifies the structure of the feeding device and reduces the cost, but also allows the size of the limiting cavity to be adjustable, making the feeding device suitable for capacitors of different diameters and improving the versatility of the feeding device. Attached Figure Description

[0015] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0016] Figure 1 This is a schematic diagram of the structure of the feeding device provided in the embodiments of this application;

[0017] Figure 2 This is a schematic diagram of the structure of the pusher provided in an embodiment of this application. Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] This application provides a feeding device for use in an aluminum electrolytic capacitor sealing machine. Specifically, the feeding device is installed on the turntable of the aluminum electrolytic capacitor sealing machine. When the turntable rotates the sealed aluminum electrolytic capacitor 300, which is in a vertical position, to the feeding position, the feeding device removes the sealed aluminum electrolytic capacitor 300 from the turntable to complete the feeding of the aluminum electrolytic capacitor 300.

[0020] Please refer to the attached document. Figure 1-2 The feeding device includes a linear driver 100 and a pusher 200. The pusher 200 is connected to the drive end of the linear driver 100 and is movable along a first direction under the drive of the linear driver 100. The first direction is the feeding movement direction of the capacitor 300. The pusher 200 forms a limiting cavity 201. The limiting cavity 201 has an opening on the side away from the linear driver 100 for the capacitor 300 to enter and exit the limiting cavity 201. The limiting cavity 201 is used to limit the displacement of the capacitor 300 located therein along a second direction. The first direction and the second direction are perpendicular to each other to prevent the capacitor 300 from deviating from the feeding path due to friction between it and the turntable when pushed by the pusher 200. This allows the capacitor 300 to reliably complete the feeding process under the drive of the pusher 200. The above-mentioned feeding device has a simple structure and low cost, which helps to reduce the cost of aluminum electrolytic capacitor sealing machines.

[0021] The size of the limiting cavity 201 can be adjusted, that is, the limiting cavity 201 can accommodate capacitors 300 of different diameters, so that the feeding device can be used for capacitors 300 of different diameters, thus improving the versatility of the feeding device.

[0022] Optionally, the linear actuator 100 is a cylinder, a hydraulic cylinder, or an electric push rod, and the driving end is the end of the drive shaft in the above structure.

[0023] In some embodiments of this application, the pusher 200 includes a plurality of push portions 210 arranged in sequence. Any two adjacent push portions 210 are connected by a connecting structure, and the plurality of push portions 210 surround a limiting cavity 201. The connecting structure has a locked state and an unlocked state, and can switch between the locked and unlocked states. In the locked state, the two push portions 210 connected by the connecting structure can rotate relative to each other. At this time, the size of the limiting cavity 201 can be adjusted by rotating the push portions 210 so that the size of the limiting cavity 201 is adapted to the size of the capacitor 300 to be driven. In the unlocked state, the positions of the two push portions 210 connected by the connecting structure are relatively fixed. At this time, the pusher 200 is a stable integral structure so that the push portions 210 will not rotate during the pushing of the capacitor 300, ensuring a reliable pushing action on the capacitor 300.

[0024] In this embodiment, the pusher 200 is formed by connecting multiple push parts 210, which not only facilitates the partial replacement of the pusher 200 and reduces maintenance costs, but also makes the size adjustment operation of the limiting cavity 201 more convenient.

[0025] Optionally, the pushing part 210 can be a pushing plate to simplify the structure of the pushing member 200.

[0026] In some embodiments of this application, an mounting tube assembly is provided between any two adjacent pushing parts 210. The mounting tube assembly includes a first mounting tube 211 and a second mounting tube 212, and the first mounting tube 211 and the second mounting tube 212 are respectively disposed on different pushing parts 210. The first mounting tube 211 and the second mounting tube 212 are staggered along a third direction, and their axes are both parallel to the third direction. The third direction, the second direction, and the first direction are perpendicular to each other. The connecting structure passes through the first mounting tube 211 and the second mounting tube 212 to serve as a pivot structure between two adjacent pushing parts 210, which helps to simplify the structure of the pushing member 200.

[0027] When the feeding device is installed on the turntable, its third direction is parallel to the axial direction of the capacitor 300.

[0028] In some embodiments of this application, the connection structure includes a connecting bolt and a nut 230. The connecting bolt passes through the first mounting tube 211 and the second mounting tube 212 and is screwed onto the nut 230. At least one of the bolt head 221 and the nut 230 is located on one side of two adjacent push portions 210 along a third direction. In the above-described connection structure, the bolt portion 222 of the connecting screw 220 forms a pivot between two adjacent push portions 210, allowing the push portions 210 to rotate around the bolt portion 222. The connecting screw 220, bolt head 221, and nut 230 cooperate to achieve state switching of the connection structure. Specifically, in the locked state, the bolt head 221 and nut 230 jointly clamp the two adjacent push portions 210; in the unlocked state, the distance between the bolt head 221 and nut 230 increases to release the clamping effect of the bolt head 221 and nut 230 on the push portions 210.

[0029] Optionally, the screw head 221 and nut 230 are located on both sides of the adjacent two push parts 210 along the third direction, and in the locked state, the screw head 221 and nut 230 respectively abut against the two sides of the push part 210 along the third direction.

[0030] In some embodiments of this application, the driving end of the linear actuator 100 is connected to one of the connection structures to avoid the driving end interfering with the rotation of the pusher 210.

[0031] Optionally, the drive end of the linear driver 100 is connected to the connecting screw 220 in the centrally located connecting structure.

[0032] This application also provides an aluminum electrolytic capacitor sealing machine, including the above-mentioned feeding device.
