Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a mechanism for cutting and welding positive and negative power lines. Background Technology

[0002] The production of the handle for the LED glowing ball toy requires manual assembly. Specifically, the positive and negative electrodes are first installed inside the bottom shell, then the button switch and the LED bulb wire are soldered on, and finally the top cover is placed on the bottom shell and locked in place with screws. For example, prior art (publication number: CN306150648S, publication date: 2020.11.03) discloses a toy handle (LED glowing ball), whose structure consists of a bottom shell, top cover, button switch, and LED bulb wire.

[0003] However, the existing assembly methods for the aforementioned products all rely on manual assembly by workers, resulting in low assembly efficiency and poor assembly quality, making it difficult to guarantee the probability of product yield. Therefore, it is necessary to design a special mechanical device for producing light-up bubble ball handles for fully automated production, thereby reducing labor costs. However, in such a mechanical device, since the toy handles need to have button switches, the button switches need to be installed in place before welding operations are performed. There are currently no automated machines on the market for welding button switches, power cords, and positive and negative electrode plates, which means that the welding action must be completed manually, making it impossible to achieve automated assembly and production of this type of toy.

The toy's bottom shell 6 has a negative electrode plate 7 and a positive electrode plate 8 respectively inserted and fitted into its front and rear ends. A button switch 9 is embedded in the toy's bottom shell 6. Two wire stripping and cutting mechanisms 10 are fixedly installed on the workbench 2. One of the wire stripping and cutting mechanisms 10 is fixedly installed with a negative wire conveying and welding device 11, and the other wire stripping and cutting mechanism 10 is fixedly installed with a positive wire conveying and welding device 12. The two wire stripping and cutting mechanisms 10 are respectively provided with a positive power line 13 and a negative power line 14. The negative power line conveying and welding device 11 conveys and welds the negative power line 14 between the negative electrode plate 7 and the push button switch 9, and the positive power line conveying and welding device 12 conveys and welds the positive power line 13 onto the positive electrode plate 8.

[0029] The principle is as follows: Two wire stripping and cutting mechanisms 10 are used to cut the positive power line 13 and the negative power line 14 respectively, and the two ends of the positive power line 13 and the negative power line 14 are stripped. After the negative power line 14 is stripped and cut, it is conveyed to the top of the bottom housing fixture 5 by the negative wire conveying welding device 11. At this time, one end of the negative power line 14 is above the negative electrode plate 7, and the other end of the negative power line 14 is above the negative welding position of the push button switch 9, and then automatic welding is performed. After the positive power line 13 is stripped and cut, it is conveyed to the top of the bottom housing fixture 5 by the positive wire conveying welding device 12. At this time, one end of the positive power line 13 is above the positive electrode plate 8, and then automatic welding is performed. This achieves the effect of automatic wiring and welding, avoids the uncertainty of manual welding, has a higher welding yield, is more efficient, and is beneficial to mass production.

The bottom side of the slide rod 1031 and one end of the pushing cylinder 1033 are both fixedly installed on the wire stripping table 101. The slide table 1032 is slidably fitted on the slide rod 1031. The pushing cylinder 1033 drives the slide rod 1031 to move closer to or away from the wire feeding mechanism. The mechanism 102 is configured such that the wire feeding motor 104 is fixedly mounted on the slide table 1032, and the wire stripping knife assembly 105 is mounted on the wire stripping table 101. The rotor of the wire feeding motor 104 drives the positive power line 13 and the negative power line 14 to be fed into the wire stripping knife assembly 105. The setting of the wire reel 15 facilitates the stable feeding of the positive power line 13 and the negative power line 14. Through the rotation of the wire feeding motor 104, the positive power line 13 and the negative power line 14 can be effectively fed into the wire stripping knife assembly 105. The wire stripping knife cuts the outer sheath at both ends of the power line, and then the movement of the pushing mechanism 103 is used to strip the outer sheath at both ends of the power line, and then the positive power line 13 and the negative power line 14 are cut and separated, which facilitates the subsequent welding operation.

[0031] Furthermore: the wire stripper assembly 105 includes a guide rail 1051, two sliding blade holders 1052, and two wire cutting cylinders 1053.

The rotor of the wire feeding motor 104 drives the positive power line 13 and the negative power line 14 to be input to the two sliding blades. Between the wire stripper 16 and the wire cutter 17 of the frame 1052, the wire cutting cylinder 1053 drives the sliding blade holder 1052 to move. The wire stripper 16 strips the wires on the positive power line 13 and the negative power line 14, and the wire cutter 17 cuts the wires on the positive power line 13 and the negative power line 14. The wire stripper 16 can be used to cut the outer sheath at both ends of the power line, and with the movement of the pushing mechanism 103, the technical effect of stripping the outer sheath can be achieved. Finally, the wire cutter 17 is used to cut and separate the positive power line 13 and the negative power line 14.
