[0029] When electronic components are stacked together, electrolyte cannot uniformly penetrate the surface of each component, which can cause some components to be insufficiently soaked, affecting their electrochemical performance, to solve the above problems, transmission mechanism 200 includes a sliding sleeve 204 rotatably mounted on the cover plate 103 by a bearing, a connecting shaft 201 is slidably connected to the sliding sleeve 204, a plurality of push strips 202 are fixedly connected to the connecting shaft 201, after the filter cage 102 is sent into the jar 101, the push strips 202 on the connecting shaft 201 are inserted into the filter cage 102, so that the push strips 202 push the electronic components when the electrolyte and the electronic components do not contact sufficiently or uniformly, which helps to improve the contact between the electronic components and the electrolyte.

[0030] Stacked components can cause bubbles to form, which can hinder the uniform penetration of electrolyte and form bubbles on the surface of the components, affecting their performance, to solve the above problems, a motor 203 is fixedly connected to the cover plate 103, a straight gear 205 is fixedly connected to the end faces of the sliding sleeve 204 and the motor 203, the motor 203 drives the output shaft to rotate, which can drive the sliding sleeve 204 to rotate through the straight gear 205, the connecting shaft 201 is driven to rotate by the sliding sleeve 204, and the push strips 202 are driven to rotate to push the electronic components, reducing the number of times workers manually handle electrolyte, reducing the risk of chemical contact and improving safety.

[0031] Further, a limiting groove 207 is formed in the connecting shaft 201, a limiting strip 206 is fixedly connected to the inside of the sliding sleeve 204 and slidably connected to the limiting groove 207, a baffle 208 is movably connected to the top end of the connecting shaft 201, a slot 209 corresponding to the baffle 208 is formed in the rack 100, the baffle 208 can be moved into the slot 209, the limiting strip 206 and the limiting groove 207 can make the connecting shaft 201 move, and the sliding sleeve 204 can always drive the connecting shaft 201 to rotate, the baffle 208 can be positioned when stirring is not needed, so that the push strips 202 do not contact the electronic components.

[0032] According to the embodiment, by pushing the electronic components into contact with the electrolyte, a rapid and automatic impregnation process can be achieved, thereby improving production efficiency.

[0033] Embodiment two:

[0034] Due to the inconsistent immersion depth of different components, capacitors with different capacities and performances may be produced, reducing the consistency and reliability of the products. To solve the above problems, in combination with Figure 4 and Figure 5 As shown in the embodiment one, the cover plate 103 is provided with a weight sensor 210 on both sides, and the cover plate 103 is slidably connected with a connecting rod 211 connected with the weight sensor 210. The connecting plates are fixedly connected with a bearing plate 212, and the filter cage 102 is placed on the bearing plate 212. The weight sensor 210 can detect the amount of electrical components placed, thereby controlling the depth of the filter cage 102 placed in the electrolyte, and ensuring the consistency of the immersion depth of the electrical components in each soaking process, thereby reducing the performance fluctuations of the products caused by the depth difference and improving the consistency of the products.

[0035] Many electrolytes may volatilize during processing. If the sealing performance is poor, the electrolyte will be lost, resulting in reduced operation efficiency, increased production cost and material waste. To ensure the sealing effect during processing, a motor two is fixedly arranged on the rack 100, the output end of the motor two is fixedly connected with a screw rod, the screw rod is threadedly connected with a connecting block 104 slidably connected with the rack 100, and the cover plate 103 is fixedly connected with the connecting block 104.

Due to the different amounts of electronic components, the gap between the cover plate 103 and the filter cage 102 is also different, and the transmission ring 301 can block the gap. When the air pump 304 is started to inject gas into the cavities, the flexible sheet 303 expands to effectively block the gap between the cover plate 103 and the filter cage 102, preventing the electrolyte from leaking or the gas from escaping, and improving the sealing performance of the system.
