Description

Technical Field

[0001] The utility model relates to the field of chip-type aluminum electrolytic capacitors, in particular to an electrolyte impregnation device for producing chip-type aluminum electrolytic capacitors. Background Art

[0002] The general production process for aluminum electrolytic capacitors is cutting → coiling → impregnation → assembly → casing → aging → testing and sorting → visual inspection → packaging → storage. The impregnation process uses physical means (heating, vacuuming, air pressure, or hydraulic pressure) to rapidly permeate the entire core package, allowing the electrolyte to fully absorb onto the surfaces of the anode and cathode foils.

[0003] The Chinese patent with announcement number CN218730459 U provides an electrolyte impregnation device for the production and processing of chip aluminum electrolytic capacitors. The device places the capacitor into the interior of the placement box, connects the two docking brackets to the shaft through a horizontal plate, docks with the positioning rod through the docking groove, and connects the positioning rod to the positioning rod for limit positioning through a limit plate. The limit plate is connected to the connecting hole through a connecting screw. The motor is turned on to drive the shaft to rotate, thereby driving the two docking brackets and the placement box to rotate, so that the electrolyte can be fully immersed in the interior of the capacitor.

[0004] To sum up, after the capacitor is impregnated with the above structure, the internal electrolyte needs to be discharged through the drain port before the impregnated capacitor can be taken out. This process wastes too much electrolyte, and it is too troublesome for the staff to disassemble the placement box, which reduces the overall impregnation efficiency and increases the disassembly and assembly burden of the staff. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an electrolyte impregnation device for the production of chip aluminum electrolytic capacitors, so as to solve the technical problems of excessive waste of electrolyte during the capacitor impregnation process, and the troublesome disassembly of the placement box by the staff, which reduces the overall impregnation efficiency and increases the disassembly and assembly burden of the staff.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an electrolyte impregnation device for the production of chip aluminum electrolytic capacitors, comprising a frame, a drive assembly being provided at one end of the frame, and a bidirectional threaded rod being connected to the output end of the drive assembly passing through the frame, a placement plate being slidably provided on the top of the bidirectional threaded rod in the frame, and a mounting column being provided at the bottom of the frame at the center position of the placement plate, an array placement box being provided on the top of the placement plate, and a T-shaped block being connected to one end of the placement box, and a T-shaped slot being provided on the mounting column for cooperating with the T-shaped block.

[0007] By adopting the above technical solution, the stepper motor is started to drive the placement plate to slide upward, and at the same time, the T-shaped block at one end of the placement box slides in the T-shaped groove, and then the limiting work of the T-shaped block is released. During this process, there is no need to manually discharge the electrolyte in the frame, which effectively prevents a large amount of electrolyte waste. At the same time, the staff can directly disassemble the placement box, which speeds up the overall impregnation efficiency and reduces the disassembly and assembly burden of the staff.

[0008] The utility model is further configured such that the driving component is a stepping motor, and the stepping motor is used to drive the bidirectional threaded rod at the output end to rotate.

[0009] By adopting the above technical solution, it is convenient for workers to control the forward and reverse rotation of the bidirectional threaded rod under the action of the stepping motor.

[0010] The utility model is further configured such that threaded sleeves are symmetrically provided on the outer wall of the bidirectional threaded rod, the top of the threaded sleeve is hinged to a support rod, and the other end of the support rod is hinged to the bottom of the placement plate.

[0011] By adopting the above technical solution, during the rotation of the bidirectional threaded rod, the threaded sleeve on the outer wall will be driven to slide inward. At this time, the support rod will push the placement plate upward. During this process, the placement plate can move upward in the frame, thereby allowing the placement plate to drive the electrolyte level on the placement box to be removed, making it easier to take it out later.

[0012] The utility model is further configured such that a matching limiting mechanism is provided at the bottom of the outer wall of the threaded sleeve located in the frame.

[0013] By adopting the above technical solution, during the rotation of the bidirectional threaded rod, the threaded sleeve will slide inward. In order to ensure the stability of the rotation of the support rod during this process, a limiting mechanism is provided on one side of the threaded sleeve. Under the action of the limiting mechanism, the threaded sleeve slides horizontally on the outer wall of the bidirectional threaded rod to prevent the threaded sleeve from rotating on its own, thereby further improving the overall practicality of the device.

[0014] The present invention is further configured such that the T-shaped block and the T-shaped groove are arranged in a smooth shape.

[0015] By adopting the above technical solution, the smooth setting reduces the sliding friction between the T-shaped block and the T-shaped slot, and prevents the T-shaped block from getting stuck in the T-shaped slot during the subsequent upward sliding of the placement plate, thereby ensuring the sliding stability of the placement plate.

[0016] The present invention is further configured such that an array of through holes is provided through the placement box.

[0017] By adopting the above technical solution, the electrolyte in the placement box can be easily drained downwards through the through hole, thereby preventing part of the electrolyte from accumulating in the placement box during the upward movement of the placement plate.

[0018] The utility model is further configured such that the connection between the bidirectional threaded rod and the frame is sealed.

[0019] By adopting the above technical solution, the sealed arrangement prevents leakage of the electrolyte in the frame at its connection points.

[0020] The present invention is further configured such that a liquid drain port is provided on one side of the frame.

[0021] By adopting the above technical solution, the internal electrolyte can be easily discharged and replaced through the drain port, thereby accelerating the overall work efficiency.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The utility model is provided with a placement plate which is slidably arranged in the frame. After the capacitor is impregnated, the placement plate is driven to slide upward by starting the stepping motor, and the T-shaped block at one end of the placement box slides in the T-shaped groove, and then the limiting work of the T-shaped block is released. In this process, there is no need to manually discharge the electrolyte in the frame, which effectively prevents the waste of a large amount of electrolyte. At the same time, the staff can directly disassemble the placement box, which speeds up the overall impregnation efficiency and reduces the disassembly and assembly burden of the staff.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] Example 1

[0033] An electrolyte impregnation device for producing chip aluminum electrolytic capacitors, such as Figure 1-Figure 5 As shown, it includes a frame 1, a stepper motor 2, a placement plate 8, a sliding mechanism, an adjustment mechanism and a limit mechanism. The staff puts electrolyte into the frame 1, and then places the capacitor to be impregnated in the placement box 3, and impregnates the capacitor in the placement box with the electrolyte. Since a stepper motor 2 is provided at one end of the frame 1, and the output end of the stepper motor 2 passes through the frame 1 and is connected to a bidirectional threaded rod 6, at the same time, a threaded sleeve 5 is symmetrically provided on the outer wall of the bidirectional threaded rod 6, wherein the top of the threaded sleeve 5 is hinged with a support rod 7, and the other end of the support rod 7 is hinged with the bottom of the placement plate 8. During the rotation of the bidirectional threaded rod 6, the threaded sleeve 5 on the outer wall will be driven to slide inward, and at this time the support rod 7 will cause the placement plate 8 to push upward. The t-shaped block 10 is convenient for operators to install and disassemble the capacitor, and it is easy to install and disassemble the capacitor.

[0034] See also Figure 2 and Figure 4 The T-shaped block 10 and the T-shaped slot 9 are arranged in a smooth shape. The smooth shape reduces the sliding friction between the T-shaped block 10 and the T-shaped slot 9. In the subsequent process of the placement plate 8 sliding upward, the T-shaped block 10 is prevented from being stuck in the T-shaped slot 9, thereby ensuring the sliding stability of the placement plate 8.

[0035] See also Figure 1 and Figure 2An array of through holes is provided in the placement box 3, which facilitates the downward discharge of the electrolyte in the placement box 3, preventing the accumulation of part of the electrolyte in the placement box 3 during the upward movement of the placement plate 8, and the connection between the bidirectional threaded rod 6 and the frame 1 is sealed, which prevents the electrolyte in the frame 1 from leaking at its connection.

[0036] Example 2

[0037] like Figure 2 The electrolyte impregnation device for the production of chip aluminum electrolytic capacitors shown in the figure has an overall structure similar to that of Example 1, wherein the outer wall of the threaded sleeve 5 is located at the bottom of the frame 1 and is provided with a matching limiting mechanism. During the rotation of the bidirectional threaded rod 6, the threaded sleeve 5 will slide inward. In this process, in order to ensure the stability of the rotation of the support rod 7, a limiting mechanism is provided on one side of the threaded sleeve 5. Under the action of the limiting mechanism, the threaded sleeve 5 slides horizontally on the outer wall of the bidirectional threaded rod 6 to prevent the threaded sleeve 5 from rotating on its own, thereby further improving the overall practicality of the device.

[0038] The working principle of the present invention is as follows: when in use, a large amount of electrolyte is added into the frame 1, and then the capacitor is placed in the placement box 3 for impregnation. After the capacitor is impregnated, the stepper motor 2 at one end of the frame 1 is started, and the cooperation of the bidirectional threaded rod 6 and the threaded sleeve 5 is realized to drive the placement plate 8 to slide upward in the frame 1. Since a mounting column 4 is also provided in the frame 1, the mounting column 4 can ensure that the placement plate 8 slides in the vertical direction in the frame 1. At the same time, a T-shaped block 10 is provided at one end of the placement box 3 to cooperate with the mounting column 4. In the process of the placement plate 8 sliding upward, the T-shaped block 10 will slide out of the T-shaped slot 9 on the mounting column 4. At this time, the staff can directly take out the placement box 3. In this process, the overall disassembly and assembly efficiency is accelerated. At the same time, there is no need to discharge the electrolyte in the frame 1, saving the overall impregnation cost.

[0039] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
