Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment, and in particular to a copper wire lamp welding positioning mechanism. 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 yield rate of the products. 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. In such a mechanical device, since the toy handles need to have push-button switches, the push-button switches need to be installed in place before the soldering operation. Specifically, the push-button switches are embedded in the circuit board, and the two ends of the copper wire lamp need to be soldered to the corresponding soldering points on the circuit board. Because the distance between the two soldering points is very close, solder bridging and solder breaks are prone to occur during manual soldering, leading to poor soldering. At the same time, there is no automated equipment on the market for soldering copper wire lamps to the circuit board for this type of toy product, making manual soldering inefficient and seriously affecting the production efficiency of toy light-up bubble ball handles.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical 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.

[0025] like Figure 1-9 As shown, the present invention provides a copper wire lamp welding positioning mechanism, including a frame 1, a workbench 2 fixedly installed on the frame 1, a slide rail 3 fixedly installed on the workbench 2, a slider 4 slidably installed on the slide rail 3, a bottom shell fixture 5 fixedly installed on the slider 4, and a toy bottom shell 6 installed inside the bottom shell fixture 5. The workbench 2 is fixedly equipped with a copper wire lamp conveying mechanism 7, a copper wire lamp moving mechanism 8, and a copper wire lamp welding mechanism 9. The copper wire lamp conveying mechanism 7 drives and connects several copper wire lamp fixtures 10. Double-wire copper wire lamps are installed in the copper wire lamp fixtures 10 with clearance fit. A circuit board 11 is set inside the toy bottom shell 6. A copper wire lamp welding position 12 is set on the circuit board 11. The copper wire lamp moving mechanism 8 picks up the double-wire copper wire lamp and conveys it above the copper wire lamp welding position 12. The copper wire lamp welding mechanism 9 is fixedly installed on the front side of the copper wire lamp moving mechanism 8. The copper wire lamp welding mechanism 9 welds and fixes the two ends of the double-wire copper wire lamp to the copper wire lamp welding position 12 of the circuit board 11 respectively. The principle is as follows: The copper wire lamp conveying mechanism 7 transports and moves several copper wire lamp fixtures 10 equipped with double-wire copper wire lamps. The copper wire lamp fixtures 10 can position the two ends of the double-wire copper wire lamps. Then, the copper wire lamp moving mechanism 8 clamps the two ends of the double-wire copper wire lamps and transports them to the copper wire lamp soldering position 12 on the circuit board 11. Alternatively, the double-wire copper wire lamps can be installed manually. Finally, the copper wire lamp soldering mechanism 9 solders the two ends of the double-wire copper lamps onto the copper wire lamp soldering position 12, realizing automated soldering operation. Compared with the existing manual soldering, the soldering yield is higher and the soldering efficiency is also higher.

[0026] Furthermore: the copper wire lamp conveying mechanism 7 adopts a belt conveyor. The copper wire lamp fixture 10 has two copper wire grooves 13 formed on it. The front side of the copper wire lamp fixture 10 has a rotating groove 14 formed on it. The rotating groove 14 is located in front of the two copper wire grooves 13. A pressure plate 15 is rotatably installed in the rotating groove 14. A spring 16 is installed between the bottom side of the pressure plate 15 and the rotating groove 14. The spring 16 drives the pressure plate 15 to flip backward and press the two ends of the double-wire copper lamp into the rotating groove 14. After the double-wire copper lamp is installed in the copper wire lamp fixture 10, the two ends of the double-wire copper lamp can be positioned in the two copper wire grooves 13 by the spring 16 driving the pressure plate 15 to elastically reset. This facilitates the clamping and positioning of the copper wire lamp transfer mechanism 8 and ensures the conveying accuracy.

[0027] Furthermore: An unlocking bracket 17 is fixedly installed on the workbench 2. The unlocking bracket 17 is located on the rear side of the copper wire lamp moving mechanism 8. An unlocking cylinder 18 is fixedly installed on the unlocking bracket 17. The unlocking cylinder 18 drives the unlocking rod 19, which is connected to the unlocking cylinder 18. The unlocking rod 19 presses against the lower end of the front side of one of the pressure plates 15. When the belt conveyor drives the copper wire lamp fixture 10 to move to the rear of the copper wire lamp moving mechanism 8, the unlocking cylinder 18 drives the unlocking rod 19 to press against the pressure plate 15, causing the pressure plate 15 to flip over and the spring 16 to be in a compressed state. At this time, the two ends of the double-wire copper lamp can be released. Then, the copper wire lamp moving mechanism 8 is used to strengthen the double-wire copper lamp and transport it into the toy bottom shell 6 for welding and fixing. This can effectively prevent the double-wire copper lamp from dislodging in the copper wire lamp fixture 10.

[0028] Furthermore, the lower end of the rotating groove 14 and the lower end of the inner side of the pressure plate 15 are both formed with recessed grooves 20, and the spring 16 is installed in the recessed grooves 20 on both sides; this ensures the stable assembly of the spring 16.

[0029] Furthermore: the copper wire lamp moving mechanism 8 includes a positioning machine platform 81, a lead screw conveyor 82, a sliding assembly 83, a first lifting cylinder 84, and a pneumatic finger 85. The positioning machine platform 81 is fixedly installed on the workbench 2, and the lead screw conveyor 82 is fixedly installed on the positioning machine platform 81. The lead screw conveyor 82 drives the sliding assembly 83 to slide back and forth. The first lifting cylinder 84 is fixedly installed on the upper end of the sliding assembly 83. The first lifting cylinder 84 drives the pneumatic finger 85 to move up and down. Both ends of the bottom side of the pneumatic finger 85 are fixedly installed with grippers 21, and a middle rod 22 is fixedly installed in the middle of the bottom side of the pneumatic finger 85. There are clamping gaps 23 between the grippers 21 on both sides and the middle rod 22. The two ends of the double-wire copper lamp are respectively installed between the left and right sides of the middle rod 22 and the grippers 21 with gap fit. By utilizing the cooperation between the middle rod 22 and the grippers 21 on both sides, two symmetrical clamping gaps 23 are formed, which can clamp the two ends of the double-wire copper lamp respectively, so as to realize the stable clamping and conveying of the double-wire copper lamp.

[0030] Furthermore: a first vertical guide rail 24 is fixedly installed on the sliding component 83, and a first vertical sliding block 25 is slidably installed on the first vertical guide rail 24. The pneumatic finger 85 is fixedly installed on the first vertical slider 4; the copper wire lamp welding position 12, which allows the middle rod 22 and the grippers 21 on both sides to descend, can be used for welding operations with higher positioning accuracy.

[0031] Furthermore, the copper wire lamp welding mechanism 9 includes a positioning plate 91, a second lifting cylinder 92, a lifting block 93, and a welding head 94. The positioning plate 91 is fixedly installed at the front end of the copper wire lamp moving mechanism 8. The second lifting cylinder 92 is fixedly installed at the upper end of the positioning plate 91. The second lifting cylinder 92 drives the lifting block 93 to move up and down. The welding head 94 is fixedly installed on the bottom side of the lifting block 93. When the welding head 94 descends, it is aligned with the copper wire lamp welding position 12 of the circuit board 11 to perform welding operations. This allows the welding head 94 to descend to the copper wire lamp welding position 12 to perform welding operations, achieving automated and stable welding.

[0032] Furthermore, a second vertical guide rail 26 is fixedly installed on the side of the positioning plate 91, and a second vertical sliding block 27 is slidably installed on the second vertical guide rail 26. The lifting block 93 is fixedly installed on the second vertical sliding block 27; this ensures the stable lifting and lowering movement of the welding head 94 and guarantees the welding effect.

[0033] Furthermore, a soldering mechanism 28 is fixedly installed on the workbench 2. The soldering mechanism 28 includes a right-angle frame 281, a third lifting cylinder 282, a horizontal rod 283, and a soldering tube 284. The right-angle frame 281 is fixedly installed on the workbench 2, and the third lifting cylinder 282 is fixedly installed on the right-angle frame 281. The third lifting cylinder 282 drives the horizontal rod 283 to move up and down. The soldering tube 284 is fixedly installed on the horizontal rod 283. Soldering holes are formed inside the soldering tube 284. The lower end of the soldering tube 284 is set on the upper side of the copper wire lamp welding position 12. The solder bar is inserted into the soldering hole of the soldering tube 284. The soldering tube 284 is moved up and down by the third lifting cylinder 282, so that the end of the solder bar moves to the copper wire lamp welding position 12. This achieves precise positioning and soldering operation, ensuring that the welding head 94 stably welds both ends of the double-wire copper lamp to the copper wire lamp welding position 12.

[0034] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model.
