Detailed Implementation

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] Reference Figures 1 to 3 The LED light strip wire welding device provided in this application embodiment is used to weld the wires on two adjacent LED light boards end to end to form an LED light strip. It includes a bracket 10 disposed above the LED light board clamp 1, a translation device 20 disposed on the bracket 10 that can move left and right, and two welding components 30 disposed on the translation device 20 and arranged in front and behind. Each welding component 30 includes a column 31, a solder wire feeding component disposed on the column 31, a vertical moving device 32 disposed inside the column 31, and a soldering iron 33 disposed on the vertical moving device 32.

[0023] In the wire welding device provided in this embodiment, the two welding components 30 arranged at the front and rear can weld the beginning and end of the wires on the LED light board respectively. That is, the welding component 30 on the front side welds the beginning of the wire to the end of the wire of the previous LED light board, and the welding component 30 on the rear side welds the end of the wire to the beginning of the wire of the next LED light board. Moreover, the translation device 20 can drive the two welding components 30 to move left and right, so that multiple light boards placed in parallel on the same fixture 1 can be welded in sequence. In this way, welding can be carried out on both sides at the same time, and multiple light boards can be welded by horizontal movement, which greatly improves efficiency and reduces cost.

[0024] Specifically, refer to Figure 2 , Figure 3 In this embodiment, the solder wire feeding assembly includes a feeding wheel assembly 34 disposed on the outside of the column 31, a solder feeding tube 35 through which the solder wire can pass, and a solder feeding nozzle 37 disposed on the up-down moving device 32 and located next to the soldering iron 33.

[0025] In this embodiment, the feeding roller assembly 34 includes a feeding roller 341 for winding solder wire and a feeding roller 342 disposed beside the feeding roller 341 for feeding the solder wire. The solder wire is located between the feeding roller 341 and the feeding roller 342. When the feeding roller 341 rotates, it uses friction to drive the solder wire to be fed out.

[0026] In addition, the solder wire feeding assembly also includes a roller assembly 36 located beside the solder feeding tube 35 for feeding solder, through which the solder wire passes. Thus, when the roller assembly 36 rotates, the solder wire located between the roller assemblies 36 also moves forward, completing the solder wire feeding.

[0027] In this embodiment, the translation device 20 includes a slide rail 21 mounted on the support 10, a cylinder 22 mounted on the support 10, and a slider 23 driven by the cylinder 22 and slidably mounted on the slide rail 21. Two collection devices 24 are also provided on both sides of the slider 23, each collection device 24 corresponding to a welding assembly 30, for collecting waste solder dross from the welding assembly 30.

[0028] In this embodiment, a drag chain 25 is also provided above the translation device 20 for placing and protecting the wire harness, so that the wire harness can move freely when the translation device 20 moves.

[0029] In this embodiment, a horizontal plate 26 is provided on the slider 23, and the two welding components 30 are symmetrically arranged on the horizontal plate 26. In this way, the horizontal plate 26 ensures that the two welding components 30 move smoothly and synchronously.

[0030] In this embodiment, the up-and-down moving device 32 includes a first rotary cylinder 321 disposed inside the column 31, a second rotary cylinder 322 disposed parallel to the first rotary cylinder 321, and a transmission structure 323 disposed between the first rotary cylinder 321 and the second rotary cylinder 322. The output shaft of the second rotary cylinder 322 is a lead screw, and a lead screw nut 324 is mounted on the lead screw. The soldering iron 33 is fixedly connected to the lead screw nut 324. When the output shaft of the second rotary cylinder 322 rotates, it drives the lead screw nut 324 to move up and down back and forth, completing the soldering and unsoldering actions. Specifically, the transmission structure 323 is a belt pulley transmission structure. The belt pulley transmission structure between the first rotary cylinder 321 and the second rotary cylinder 322 makes the rotation of the two rotary cylinders more stable, thereby ensuring that the soldering iron 33 can solder more accurately.

[0031] In summary, the wire welding device provided in this application embodiment has a simple structure, can weld both ends of the lamp board at the same time, and can achieve welding of multiple lamp boards through the translation device 20, thereby improving production efficiency and reducing labor costs.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
