An automatic capacitor glue filling equipment

Abstract

This application relates to an automated capacitor potting equipment, including a feeding mechanism, a pushing mechanism, a positioning mechanism, and a potting mechanism. The positioning mechanism has multiple positioning grooves extending longitudinally and arranged in parallel laterally. Each positioning groove includes a first groove whose cross-section corresponds to the capacitor's outer casing. A second groove and a third groove are positioned above the first groove, their cross-sections corresponding to the two leads of the capacitor. A fourth groove is positioned between the second and third grooves for the potting mechanism to pass through. By forming the first, second, third, and fourth grooves in the positioning mechanism, the capacitor's outer casing is embedded in the first groove, and the two leads are embedded in the second and third grooves. This ensures that the roots of the two leads are confined by the inner wall of the second groove, preventing them from tipping over due to their own weight and guaranteeing a high processing yield.

Description

Technical Field

[0001] This application relates to the field of capacitor manufacturing technology, and in particular to an automated capacitor potting equipment. Background Technology

[0002] In the manufacturing process of capacitors, the potting process is a crucial step in ensuring their stable performance. Typically, capacitor potting involves first fixing the capacitor core onto a tooling fixture, then using potting equipment to inject potting compound into the capacitor casing. This seals, insulates, and protects the core from moisture, ensuring the capacitor can withstand harsh environments and maintain normal electrical performance during subsequent use. Currently, most capacitor potting processes on the market are completed using automated or semi-automated equipment. The basic process includes feeding, positioning, potting, and curing. The precision and stability of the potting process directly affect the final quality of the capacitor.

[0003] However, existing automated capacitor potting equipment still suffers from poor potting results in practical applications. When the potting compound is injected into the casing, during its solidification process, the capacitor leads are usually quite long and lack effective fixation and support. They are easily misaligned due to their own weight or the flow of the potting compound, resulting in the leads being tilted after the potting compound solidifies. This tilting of the leads not only affects the appearance quality of the capacitor but may also cause the distance between the leads and other components to not meet design requirements, thereby causing potential electrical performance problems, reducing the product qualification rate, and increasing rework costs later. Utility Model Content

[0004] This application provides an automated capacitor potting device with better potting effect.

[0005] The automated capacitor potting equipment provided in this application adopts the following technical solution: An automated capacitor potting device includes a feeding mechanism, a pushing mechanism, a positioning mechanism, and a potting mechanism. The pushing mechanism and the positioning mechanism are located on opposite sides of the feeding mechanism. The pushing mechanism pushes material from the feeding mechanism into the positioning mechanism. The potting mechanism is positioned above the positioning mechanism. The positioning mechanism has multiple longitudinally extending positioning grooves arranged in parallel laterally. Each positioning groove includes a first groove whose cross-section corresponds to the outer casing of the capacitor. A second groove and a third groove are provided above the first groove, whose cross-sections correspond to the two leads of the capacitor. A fourth groove is provided between the second and third grooves for the potting mechanism to pass through.

[0006] Preferably, the feeding mechanism includes a conveyor belt arranged laterally, and the pushing mechanism and the positioning mechanism are arranged longitudinally on both sides of the conveyor belt; a sensing stop plate is provided on the left side of the positioning mechanism, and the sensing stop plate is located above the conveyor belt.

[0007] Preferably, the pushing mechanism includes a pushing motor, which drives multiple mounting plates along the longitudinal direction. The multiple mounting plates are aligned with multiple positioning slots. One end of each mounting plate facing away from the pushing mechanism is provided with a housing pusher and two lead pushers. The housing pusher faces the first slot and is used to abut against the capacitor housing via the pushing motor. The two lead pushers face the second slot and the third slot respectively and are used to abut against the two leads respectively via the pushing motor.

[0008] Preferably, the end of the lead pusher is formed with a groove that matches the lead of the capacitor, the groove being used for embedding the lead.

[0009] Preferably, the dispensing mechanism includes a slide rail and a vertical drive motor that slides longitudinally on the slide rail. The vertical drive motor drives a dispensing kit, which is located above the positioning mechanism. The dispensing kit includes dispensing heads that match the number of positioning slots, and multiple dispensing heads are correspondingly inserted into the fourth slot.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by forming a first groove, a second groove, a third groove, and a fourth groove in the positioning mechanism, ensures that when the capacitor is pushed into the positioning groove by the pushing mechanism, the capacitor's outer casing is correspondingly embedded in the first groove, and the two leads of the capacitor are correspondingly embedded in the second and third grooves. This allows the roots of the two leads to be restricted by the inner wall of the second groove, making them less likely to tilt due to their own weight. This ensures that the roots of the leads can be further fixed in the capacitor's outer casing in a vertical state by potting compound, thus ensuring a high processing yield.

[0011] 2. By setting a housing pusher and a lead pusher, and setting a groove at the end of the lead pusher, the housing and lead of the capacitor can be pushed in a targeted manner, ensuring that the lead can enter the second and third grooves. At the same time, the groove increases the fit between the lead and the lead pusher, further optimizing the pushing effect of the pushing mechanism.

[0012] 3. By setting up slide rails and a vertical drive motor, the dispensing kit can move longitudinally and vertically, improving the flexibility of dispensing. Attached Figure Description

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides an automated capacitor potting device, such as... Figures 1 to 7 As shown, it includes a feeding mechanism 1, a pushing mechanism 2, a positioning mechanism 3, and a dispensing mechanism 4. The pushing mechanism 2 and the positioning mechanism 3 are located on both sides of the feeding mechanism 1. The pushing mechanism 2 is used to push the material from the feeding mechanism 1 into the positioning mechanism 3. The dispensing mechanism 4 is located above the positioning mechanism 3.

[0023] like Figure 1 and Figure 2 As shown, the feeding mechanism 1 includes a conveyor belt 11, which is arranged laterally. The pushing mechanism 2 and the positioning mechanism 3 are arranged longitudinally on both sides of the conveyor belt 11. A sensing stop plate 32 is provided on the left side of the positioning mechanism 3. The sensing stop plate 32 is located above the conveyor belt 11. When multiple capacitors to be potted are transported between the pushing mechanism 2 and the positioning mechanism 3, and the leftmost capacitor touches the sensing stop plate 32, the conveyor belt 11 stops conveying. At this time, the pushing mechanism 2 pushes multiple capacitors into the positioning mechanism 3.

[0024] like Figure 3 and Figure 4 As shown, the feeding mechanism 2 includes a feeding motor 21, which drives multiple mounting plates 22 longitudinally. The mounting plates 22 are aligned with multiple positioning slots 31. One end of each mounting plate 22 facing away from the feeding mechanism 2 is provided with a housing pusher 23 and two lead pushers 24. The housing pusher 23 faces the first slot 311 and is used to abut against the capacitor housing via the feeding motor 21. The lead pushers 24 face the second slot 312 and the third slot 313 respectively. The ends of the lead pushers 24 have grooves 241 that match the capacitor leads. The grooves 241 are used for lead embedding and for abutting against two leads via the feeding motor 21. Conveyor belt 11 conveys multiple capacitors to be potted to the space between pusher mechanism 2 and positioning mechanism 3. When the leftmost capacitor contacts the induction stop plate 32, the capacitor, mounting plate 22 and positioning groove 31 are aligned. Pusher motor 21 drives mounting plate 22 to move closer to positioning groove 31. Housing pusher head 23 abuts against the housing of the capacitor. Two lead pushers 24 abut against the roots of the two leads respectively. The leads can be embedded in the groove 241, so that the leads fit the lead pusher head 24 better. Housing pusher head 23 and lead pusher head 24 cooperate to push the housing of the capacitor into the first groove 311 and push the two leads into the second groove 312 and the third groove 313 respectively.

[0025] like Figure 5 and Figure 6 As shown, the positioning mechanism 3 has multiple longitudinally extending positioning grooves 31. Multiple capacitors can be longitudinally positioned within each positioning groove 31. The multiple positioning grooves 31 are arranged in parallel laterally. Each positioning groove 31 includes a first groove body 311, the cross-section of which corresponds to the outer shell of the capacitor. A second groove body 312 and a third groove body 313 are respectively positioned above the first groove body 311, the cross-sections of which correspond to the two leads of the capacitor. The capacitor is pushed in by the pushing mechanism 2. After the positioning groove 31, the capacitor shell is embedded in the first groove 311, and the roots of the two leads of the capacitor are respectively embedded in the second groove 312 and the third groove 313. A fourth groove 314 is provided between the second groove 312 and the third groove 313. After the capacitor enters the positioning groove 31, the capacitor's potting port is aligned with the fourth groove 314. The fourth groove 314 is used for the potting mechanism 4 to pass through. The potting mechanism 4 aligns with the fourth groove 314 and pours potting compound into the capacitor's potting port.

[0026] like Figure 7As shown, the dispensing mechanism 4 includes a slide rail 41 and a vertical drive motor 42 that slides longitudinally on the slide rail 41. The slide rail 41 is located on both sides of the positioning mechanism 3 and its top is higher than the positioning mechanism 3. The vertical drive motor 42 drives the dispensing kit 43, which is located above the positioning mechanism 3. The dispensing kit 43 includes dispensing heads 431 that match the number of positioning slots 31. Multiple dispensing heads 431 are inserted one-to-one into the fourth slot 314. During dispensing, the dispensing kit 43 is driven by the slide rail 41 and the vertical drive motor 42, so that multiple dispensing heads 431 are inserted into the fourth slot 314 and move longitudinally to inject potting glue into the capacitor.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
