Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte injection devices, and in particular to an electrolyte injection device for capacitor processing. Background Technology

[0002] Electrolyte injection devices in capacitor manufacturing are highly precise and automated equipment specifically designed to inject and fill precisely metered electrolyte during the production of electrolytic capacitors. Their core components typically include a supply system (for storing and transporting electrolyte), a precision metering system (such as a plunger pump, peristaltic pump, or precision valve), and injection needles or nozzles.

[0003] However, in existing electrolyte injection devices, capacitors are typically placed on a mounting base during use, allowing for the injection of electrolyte into multiple capacitors at once. However, mounting bases of different sizes are not easy to place and position quickly. If the capacitor mounting base is not stable enough, the injection needle may scrape against the casing, or even fail to fully insert into the injection port or deviate from the intended position, leading to leakage or contamination. Therefore, those skilled in the art have provided an electrolyte injection device for capacitor processing to solve the problems mentioned in the background art. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1-4 This utility model provides an electrolyte injection device for capacitor processing, including a fixed bracket 1, an installation housing 2 installed at the bottom of the fixed bracket 1, and an electrolyte injection mechanism body 3 installed inside the fixed bracket 1. The electrolyte injection mechanism body 3 is mainly used for the quantitative supply of chemical liquid in the capacitor production process. The specific structure can be referred to a capacitor quantitative liquid injection machine (authorization announcement number CN 203367028 U). The bottom of the installation housing 2 is equipped with self-locking casters 4. The inner bottom wall of the fixed bracket 1 is provided with a worktable 5. The top of the worktable 5 is equipped with an adjustable positioning mechanism 6 and a stabilizing mechanism 7.

[0034] The adjustable positioning mechanism 6 includes a servo motor 61. A ball screw 62 is fixed to one end of the output shaft of the servo motor 61. A first ball nut 63 is threaded to the outer side of the ball screw 62, and a second ball nut 64 is threaded to the outer side of the ball screw 62. A limit frame 65 is fixed to one side of both the first ball nut 63 and the second ball nut 64. A mounting bracket 66 is installed on the top of the worktable 5. A through groove is opened inside the limit frame 65. A guide sliding block 67 is slidably connected to the limit frame 65 through the through groove. A limit connecting sleeve 68 is fixed to the top of the guide sliding block 67. A metal nut 69 is installed on the top of the limit connecting sleeve 68. A metal threaded rod 610 is threaded to the top of the metal nut 69. An auxiliary positioning plate 611 is fixed to one side of the guide sliding block 67. The limit frame 65... Multiple positioning holes 612 are provided on the top of the device. The size of the positioning holes 612 is adapted to the size of the metal threaded rod 610. When one end of the metal threaded rod 610 is movably inserted into the corresponding positioning hole 612, the position of the limiting connecting sleeve 68 and the guide sliding block 67 can be easily fixed. The servo motor 61 and the worktable 5 are fixedly connected. The limiting frame 65 is movably sleeved on the outside of the ball screw 62. The threads inside the first ball nut 63 and the second ball nut 64 are opposite in direction. The limiting connecting sleeve 68 is movably sleeved on the outside of the limiting frame 65. When the ball screw 62 rotates, the first ball nut 63 and the second ball nut 64 move in opposite directions. The auxiliary positioning plate 611 and the guide sliding block 67 are welded and fixed together. The bottom surface of the limiting frame 65 is in contact with the top surface of the worktable 5.

[0035] The stabilizing mechanism 7 includes an L-shaped bracket 71, with a connecting threaded post 72 fixed to the top of the L-shaped bracket 71. A positioning nut 73 is threadedly connected to the outer side of the connecting threaded post 72. A limit sleeve 74 is installed on the top of the worktable 5. An anti-detachment slider 75 is slidably connected to the limit sleeve 74 through a slide groove. A reinforcing plate 76 is fixed to the top of the anti-detachment slider 75. The reinforcing plate 76 is movably sleeved on the outer side of the connecting threaded post 72. The L-shaped bracket 71 and the servo motor 61 are fixedly connected.

[0036] Working principle: With an adjustable positioning mechanism 6, when injecting electrolyte for capacitor processing, multiple capacitors are placed on corresponding placement seats. The placement seats are then placed on the worktable 5. After starting the servo motor 61, the ball screw 62 rotates. Because the internal threads of the first ball nut 63 and the second ball nut 64 are opposite, the two limit frames 65 can move in opposite directions. After the two limit frames 65 are clamped on the outside of the placement seats, the guide sliding block 67 and the limit connecting sleeve 68 can be moved horizontally, allowing the corresponding surfaces of the auxiliary positioning plate 611 to simultaneously contact the placement seats. Then, the electrolyte injection mechanism body 3 can be started to perform the electrolyte injection process for capacitor processing, which can be completed quickly. The positioning of the same-sized placement base facilitates the injection of electrolyte for capacitor processing, avoiding situations where the injection needle scratches the outer shell, cannot be fully inserted into the injection port, or is misaligned, thus reducing the risk of leakage or contamination. With the stabilizing mechanism 7, after the servo motor 61 is fixed on the top of the worktable 5, the bottom surface of the L-shaped bracket 71 on the outside of the servo motor 61 is attached to the worktable 5. Pushing the anti-detachment slider 75 moves the reinforcing plate 76, allowing the reinforcing plate 76 to be movably sleeved on the outside of the connecting threaded post 72. Finally, the positioning nut 73 and the connecting threaded post 72 are threaded together, conveniently completing the connection and reinforcement of the servo motor 61 and the worktable 5, and improving the assembly stability of the servo motor 61.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
