Technical Field

[0001] This utility model relates to the field of glue-potting equipment technology, specifically to a splash-proof film capacitor glue-potting equipment. Background Technology

[0002] Film capacitors are electronic components that use a thin film as the dielectric. They are commonly used in electronic circuits for functions such as filtering, coupling, and insulation. The main purpose of the potting compound for film capacitors is to protect them from external environmental influences, preventing them from getting damp, oxidized, or mechanically damaged.

[0003] Most film capacitor potting equipment currently on the market are similar in overall structure. They mainly use a screw pump to deliver adhesive to the potting head, and the potting head is positioned by two sets of single-axis servo drive units to pot the capacitor below. In actual use, there are some functional deficiencies and room for improvement. For example, the height of the potting head is fixed, and during the potting process, the adhesive is prone to splashing when it first drips, which affects the appearance of the product. It does not have the function of preventing adhesive splashing.

[0004] Now, a novel anti-splashing film capacitor potting device is proposed to solve the above problems. Utility Model Content

A miniature electric cylinder is fixedly connected inside the electric cylinder mounting groove, and a traction plate is fixedly connected to the outside of the glue injection head.

[0008] As a further technical solution of this utility model, the outer diameter of the dispensing head is adapted to the inner diameter of the pre-opened movable groove, and the dispensing head can slide up and down along the inside of the pre-opened movable groove.

[0009] As a further technical solution of this utility model, the top of the dispensing head is connected to the glue delivery pipe, and the glue delivery pipe, the dispensing head, and the dropper are internally connected.

[0010] As a further technical solution of this utility model, the inner diameter of the pipeline through the groove is larger than the outer diameter of the adhesive delivery pipe, the output end of the micro electric cylinder is fixedly connected to the bottom end of the traction plate, and the PLC controller and the micro electric cylinder are electrically connected.

[0025] The outer diameter of the dispensing head 13 is matched with the inner diameter of the pre-opened movable groove 11. The dispensing head 13 can slide up and down along the inside of the pre-opened movable groove 11. The top of the dispensing head 13 is connected to the glue delivery pipe 3. The glue delivery pipe 3, the dispensing head 13, and the nozzle 14 are connected internally. The inner diameter of the pipe through groove 10 is larger than the outer diameter of the glue delivery pipe 3.

With the help of the fixture, batch dispensing can be achieved. When dispensing, the micro electric cylinder 15 retracts, and the dispensing head 13 is pressed down along the pre-opened movable groove 11 by the traction plate 16, so that its position is lowered, thereby reducing the distance between the glue and the capacitor and making it less likely to splash.

The positions and dimensions of the positioning grooves 18 and the positioning blocks 21 correspond one-to-one. The positioning blocks 21 can move back and forth along the inside of the positioning grooves 18 to facilitate the positioning of the fixture.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, the fixture frame 19 is placed horizontally on the workbench 1. The fixture frame 19 is pushed toward the positioning plate 17, the positioning block 21 is inserted into the positioning groove 18, and the handle 22 is pressed against the positioning plate 17 to complete the positioning, which facilitates the precise positioning of the dispensing head 13.

[0031] Working Principle: In use, the screw pump 2 first pumps the adhesive through the adhesive delivery pipe 3 to the dispensing head 13, where it is dispensed through the nozzle 14. Two servo drive units, the longitudinal single-axis servo drive unit 5 and the transverse single-axis servo drive unit 7, control the position of the dispensing head 13. With the help of the fixture, batch dispensing can be achieved. When dispensing, the micro-cylinder 15 retracts, and the traction plate 16 presses the dispensing head 13 down along the pre-opened movable groove 11, lowering its position and reducing the distance between the adhesive and the capacitor, thus preventing splashing. Multiple fixture frames 19 are prepared for dispensing. The capacitor to be dispensed is placed in the capacitor placement groove 20 with the opening facing upwards. The handle 22 facilitates gripping and transferring the fixture frame 19. The fixture frame 19 is placed horizontally on the worktable 1. Pushing the fixture frame 19 towards the positioning plate 17, the positioning block 21 engages with the positioning groove 18, and the handle 22 presses against the positioning plate 17, completing the positioning and facilitating precise positioning of the dispensing head 13.
