They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0023] To address the problems existing in the background art, this application proposes the following technical solution: A tape feeding table 1 is included, with a placement groove 2 on the tape feeding table 1. A first feeding groove 3 and a second feeding groove 4 are provided on one side of the tape feeding table 1. A carrier tape 5 is placed in the first feeding groove 3, and hot melt adhesive is placed on one side of the carrier tape 5. A cover tape 6 is placed in the second feeding groove 4. A tape feeding groove 7 is provided in the tape feeding table 1, and the tape feeding groove 7 is internally connected to the first feeding groove 3 and the second feeding groove 4. A heating box 8 is fixedly installed on the side wall of the tape feeding groove 7, and the carrier tape 5 contacts the box body of the heating box 8. A heating resistance wire 9 is fixedly installed in the heating box 8. A sliding groove 10 is provided on one side of the tape feeding groove 7, and a slider 11 is slidably arranged in the sliding groove 10. A rotating plate 14 is provided on one side of the slider 11. A discharge groove 21 is provided on one side of the tape feeding table 1, and a driving mechanism is provided in the tape feeding table 1.

[0024] Carrier tape 5 and cover tape 6 are rhythmically and intermittently fed into the tape tray 1 by an external stepping feeding device. The aluminum electrolytic capacitor body consists of capacitor 29 and pins 30. Pins 30 are fixedly installed at the bottom of capacitor 29. The aluminum electrolytic capacitor body to be processed is placed into the placement slot 2 by manual operation or an external robot. Pins 30 are located in the tape tray 7. After carrier tape 5 and cover tape 6 are fed into the tape tray 7, pins 30 are located between carrier tape 5 and cover tape 6. The heat generated by the heating resistance wire 9 when it is working raises the temperature of the heating box 8. Since the carrier tape 5 is in contact with the surface of the heating box 8, the hot melt adhesive on the side of the carrier tape 5 near the cover tape 6 is melted through heat transfer. The drive mechanism drives the slider 11 to move in the slide 10. The slider 11 moves the rotating plate 14, which pushes the cover tape 6 to fit against the carrier tape 5. The molten hot melt adhesive bonds the cover tape 6 to one side of the carrier tape 5. The taped aluminum electrolytic capacitor can be pulled by a robot. After the hot melt adhesive is fixed, the pins 30 are firmly fixed between the carrier tape 5 and the cover tape 6, completing the taping of the aluminum electrolytic capacitor. The carrier tape 5 and the cover tape 6 after taping are discharged from the discharge trough 21. The taped carrier tape 5 and the cover tape 6 are pulled by an external stepping traction device. The stepping feeding device and the stepping traction device have the same production rhythm. The two are directly coordinated and linked by a programmable PLC controller. The hot melt adhesive improves the taping firmness of the aluminum electrolytic capacitor, thereby improving product quality.

[0025] To further explain, a roller 15 is rotatably mounted on one end of the rotating plate 14, two sets of mounting seats 12 are fixedly mounted on one side of the slider 11, a rotating shaft 13 is rotatably mounted between the two sets of mounting seats 12, the rotating plate 14 is fixedly connected to the outside of the rotating shaft 13, and torsion springs 16 are fixedly mounted on both sides of the rotating plate 14. One end of the torsion spring 16 is fixedly connected to the mounting seat 12, and the torsion spring 16 is sleeved on the outside of the rotating shaft 13.

[0026] Roller 15 is made of elastic rubber. When slider 11 moves, it drives mounting base 12 to move. Mounting base 12 drives rotating shaft 13, rotating plate 14 and roller 15 to move. As slider 11 moves, when roller 15 moves to pin 30, the rotating plate 14 rotates due to the obstruction of pin 30. The rotating plate 14 causes torsion spring 16 to twist. The torsion spring 16, in order to return to its initial state, drives rotating plate 14 to reverse, so that rotating plate 14 tends to rotate towards pin 30. Thus, roller 15 always keeps in contact with cover tape 6 and always applies pressure to cover tape 6, ensuring that cover tape 6 is stably attached to one side of carrier tape 5 and improving tape weaving quality.

[0027] To further explain, the drive mechanism includes a servo motor 17 fixedly installed in the tape tray 1. A reciprocating lead screw 18 is coaxially fixedly connected to the drive shaft of the servo motor 17. The reciprocating lead screw 18 is rotatably installed in the slide groove 10. The slider 11 is threadedly connected to the reciprocating lead screw 18.

[0028] The servo motor 17 drives the reciprocating screw 18 to rotate, and the reciprocating screw 18 pushes the slider 11 to move back and forth in the slide groove 10. When taping a set of aluminum electrolytic capacitors, the slider 11 moves from the starting position on the left, driving the roller 15 to move from left to right, and attaching the cover tape 6 to one side of the carrier tape 5. After the slider 11 moves to the right side of the slide groove 10, it moves back, driving the roller 15 to press over the cover tape 6 again, improving the bonding quality between the cover tape 6 and the carrier tape 5. The servo motor 17 is electrically connected to the controller, so that the working rhythm of the roller 15 is consistent with the feeding and discharging equipment, so that the device tapers the aluminum electrolytic capacitors according to the predetermined program rhythm, ensuring the production rhythm of the device. The reciprocating screw 18 is equipped with an accordion-style telescopic protective cover. The accordion-style telescopic protective cover is an existing product, made of PVC or rubber folded to adapt to the movement of the slider 11.

[0029] To further explain, the upper and lower ends of the slide 10 are fixedly connected with limit strips 19, and the upper and lower ends of the slider 11 are provided with limit grooves 20, and the limit strips 19 and the limit grooves 20 are slidably connected.

[0030] The limiting strip 19, together with the limiting groove 20, guides and limits the movement of the slide 10, preventing the slide 10 from flipping over when the reciprocating screw 18 rotates, improving the stability of the slider 11 when it moves, and thus improving the stability of the roller 15 when it moves, ensuring the quality of tape feeding.

[0031] To further explain, two sets of cooling boxes 22 are fixedly installed in the tape groove 7. A heat-conducting plate 23 is fixedly connected to the opposite side of the two sets of cooling boxes 22. Several sets of heat dissipation fins 24 are fixedly installed on one side of the heat-conducting plate 23. Several sets of heat dissipation fins 24 are arranged in the cooling box 22. A heat dissipation groove 27 is opened on the outer surface of the cooling box 22.

[0032] Two sets of heat-conducting plates 23 are respectively in contact with the braided carrier tape 5 and cover tape 6. The braided carrier tape 5 and cover tape 6 are moved to the position of the cooling box 22 and are in contact with the heat-conducting plates 23. The heat-conducting plates 23 absorb the temperature of the carrier tape 5 and cover tape 6, causing the molten hot melt adhesive to solidify quickly, firmly bonding the carrier tape 5 and cover tape 6 together, ensuring the fixing effect of the braided tape on the pin 30, and improving product quality. The setting of heat dissipation fins 24 increases the heat dissipation area of ​​the heat-conducting plates 23, improves the heat exchange efficiency between the heat-conducting plates 23 and the carrier tape 5 and cover tape 6, and improves the cooling effect on the carrier tape 5 and cover tape 6. The heat in the cooling box 22 is discharged through the heat dissipation groove 27, ensuring the cooling effect of the heat-conducting plates 23.

[0033] Furthermore, the bottom of the tape tray 1 is fixedly connected to a support base 28, and the bottom of the tape tray 1 is provided with two sets of air inlets 25. A cooling fan 26 is fixedly installed in each of the two sets of air inlets 25, and the air inlets 25 are connected to the inside of the cooling box 22.

[0034] The support base 28 suspends the bottom of the tape tray 1. The cooling fan 26 accelerates the airflow in the air inlet 25, drawing in external air. The rapidly flowing air enters the cooling chamber 22 through the air inlet 25, carrying away the heat from the surface of the heat-conducting plate 23 and the heat dissipation fins 24. The air carrying heat is discharged from the heat dissipation slot 27, further improving the cooling effect of the heat-conducting plate 23 on the carrier tape 5 and the cover tape 6, allowing the molten hot melt adhesive to cool and solidify quickly. A dust filter is installed at the entrance of the air inlet 25 to prevent external air from carrying dust into the cooling chamber 22.

[0035] The external stepping feeding device, stepping traction device, controller, heating resistance wire 9, servo motor 17, and cooling fan 26 of the tape and reel machine for aluminum electrolytic capacitor production of this utility model are all purchased from the market and are existing technologies. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art. The electrical connections between the electrical components and the controller programming all adopt conventional technologies. This utility model does not involve improvements to the circuit connection and control program.

[0036] For specific operation, please refer to the following: The carrier tape 5 and cover tape 6 are fed into the tape tray 1 via an external stepper feeder. The aluminum electrolytic capacitor body to be processed is placed into the placement slot 2 manually or by an external robotic arm, with the leads 30 located in the tape tray 7. After the carrier tape 5 and cover tape 6 are fed into the tape tray 7, the stepper feeder stops working, and the leads 30 are located between the carrier tape 5 and the cover tape 6. The heating resistance wire 9 operates, raising the temperature of the heating box 8, melting the hot melt adhesive on the side of the carrier tape 5 closest to the cover tape 6. The servo motor 17 operates, driving the reciprocating screw 18 to rotate, and the reciprocating screw 18 pushes the slider 1. 1. The slide 11 moves back and forth once in the chute 10. When the slide 11 moves, it drives the mounting base 12 to move. The mounting base 12 drives the rotating shaft 13, rotating plate 14 and roller 15 to move. The roller 15 applies pressure to the cover strip 6, so that the cover strip 6 adheres to one side of the carrier belt 5. The molten hot melt adhesive makes the cover strip 6 stick to one side of the carrier belt 5. The stepping feeding device and the stepping traction device work together to drive the carrier belt 5 and the cover strip 6 to continue to move between the two sets of cooling boxes 22, so that the molten hot melt adhesive cools and solidifies quickly. The carrier belt 5 and the cover strip 6 are tightly and firmly bonded together, fixing the lead 39 of the aluminum electrolytic capacitor between the two.
