Description

Technical Field

[0001] This utility model relates to the technical field of string light welding machines, and specifically to a hot air welding device for string light welding machines. Background Technology

[0002] Existing string light welding machines, used for producing string lights, first cut the plastic coating around copper wires, then apply solder paste to the copper wires, place the LED beads on the solder paste, and finally cure the solder paste to fix the beads in place. These machines use a soldering iron, which requires the iron to contact the copper wires. The iron is used to push the wires upwards to bring the copper wires, solder paste, and LED beads into contact. However, the soldering iron easily becomes covered in solder paste, affecting its usability. Furthermore, the solder paste used for soldering the copper wires and LED beads may be pulled out, resulting in incomplete or excessive soldering, leading to poor welding quality and impacting product quality.

[0003] Therefore, based on the aforementioned shortcomings of existing string light welding machines, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a string light welding machine that addresses the shortcomings of existing technologies. The hot air welding device of this string light welding machine solves the defects of existing string light welding machines, such as poor welding effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A hot air welding device for a string light welding machine includes a base, on which a hot air gun and a lifting plate are mounted. The hot air gun has a hot air nozzle with its opening facing upwards. A lifting cylinder is fixed to the base, and the lifting cylinder drives the lifting plate to rise and fall. An air blowing pipe is vertically fixed on the lifting plate, and the air blowing pipe is located directly above the hot air nozzle of the hot air gun.

[0007] Furthermore, a fixing groove is provided on the base, a slide rail is installed in the fixing groove, a fixing seat is slidably mounted on the slide rail, the hot air gun is mounted on the fixing seat, and the fixing seat drives the hot air gun to move in the Y direction.

[0008] Furthermore, a mounting plate is fixed to the side of the base, and a lifting cylinder is vertically fixed on the mounting plate. The lifting cylinder drives the lifting plate to move up and down in the vertical direction, so that the air blowing pipe moves downward toward the hot air nozzle or upward away from the hot air nozzle.

[0009] Furthermore, a fixing block is fixed to the side of the fixed base, and a horizontal cylinder is installed on the base. The horizontal cylinder drives the fixing block to move the fixed base horizontally.

[0010] Furthermore, the horizontal mounting of the hot air gun reduces the overall height.

[0011] Furthermore, the air blowing pipe is a ceramic pipe, which has the effects of high temperature resistance and wear resistance.

[0012] Furthermore, an upper baffle is installed above the horizontal cylinder, and the upper baffle is fixedly connected to the mounting plate, with the cable passing over the upper baffle.

[0013] Furthermore, a front baffle is installed above the hot air gun, the top surface of the front baffle is lower than the top surface of the hot air nozzle, and the cable passes over the front baffle.

[0014] Furthermore, a slide block is fixed to the bottom of the base, and the slide block has a mounting groove that is perpendicular to the fixing groove of the base, enabling the base to move in the X direction.

[0015] The beneficial effects of this utility model are as follows: by blowing air downward through the air tube, the LED beads are made to make stable contact with the solder paste downward, and the hot air nozzle of the hot air gun blows hot air upward, so that the solder paste and the LED beads are stably soldered together, ensuring the integrity of the solder paste soldering and improving the soldering effect.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] See Figure 1 —— Figure 4 The present invention relates to a hot air welding device for a string light welding machine, comprising: a base 1, on which a hot air gun 2 is installed. The hot air gun 2 is installed horizontally to reduce the height of the entire device. The hot air gun 2 has a hot air nozzle 3 with the opening of the hot air nozzle 3 facing upward, and hot air is blown vertically upward.

[0024] The base 1 of this utility model has a mounting plate 7 fixed on its side. A lifting cylinder 4 is fixed on the mounting plate 7. The lifting cylinder 4 is installed vertically and drives the lifting plate 5 upward. An air blowing pipe 6 is fixed on the lifting plate 5. The air blowing pipe 6 is installed vertically at the bottom of the lifting plate 5. An air supply pipe is connected to the outside of the air blowing pipe 6. The air blowing pipe 6 is located directly above the hot air nozzle 3 of the hot air gun 2.

[0025] The air blowing tube 6 of this utility model is a ceramic tube made of ceramic material, which can withstand high temperature and wear. The hot air blown out by the hot air nozzle 3 will not affect the air blowing tube 6.

[0026] The base 1 of this invention has a fixing groove 9, and a slide rail 10 is installed in the fixing groove 9. A fixing seat 8 slides on the slide rail 10, and the hot air gun 2 is installed on the fixing seat 8. A fixing block 11 is fixed to the side of the fixing seat 8, and a horizontal cylinder 12 is installed on the base 1. The horizontal cylinder 12 drives the fixing block 11 to move horizontally, which in turn causes the fixing seat 8 to move the slide rail 10 of the hot air gun 2, thereby adjusting the relative position of the hot air nozzle 3 of the hot air gun 2 on the string welding machine, and better matching the production of the wire 16.

[0027] An upper baffle 13 is installed above the horizontal cylinder 12 of this utility model. The leather cable 16 passes through the upper baffle 13, and the upper baffle is fixedly connected to the mounting plate 7.

[0028] The hot air gun 2 of this utility model has a front baffle 14 installed on top, and the cable 16 passes over the front baffle 14. The top surface of the front baffle 14 is lower than the top surface of the hot air nozzle 3.

[0029] The base 1 of this utility model has a slide 15 fixed at its bottom. The slide 15 is installed on the movable slide rail of the string light welding machine, which can adjust the position of the hot air gun 2 on the string light welding machine. The mounting groove of the slide 15 is perpendicular to the fixing groove 9 of the base 1. The slide 15 can move in the X direction, and the hot air gun 2 can move in the Y direction.

[0030] like Figure 3 , Figure 4 As shown, when this utility model is working, the wire 16 moves from above the front baffle 14, above the hot air nozzle 3 of the hot air gun 2, below the air blowing pipe 6, and above the upper baffle 13. The lifting cylinder 4 drives the lifting plate 5 to move up and down, causing the air blowing pipe 6 to slightly contact and press down on the lamp bead 18. The downward blowing of air by the air blowing pipe 6 can make the lamp bead 18 press down, making the contact between the lamp bead 18 and the solder paste on the copper wire 17 more stable. The hot air nozzle 3 blows hot air upward to solidify the solder paste, thereby fixing the lamp bead 18.

[0031] This invention uses an air blower 6 to blow the LED bead 18 downwards. The ceramic material air blower 6 prevents the LED bead 18 from sticking. The air blower 18 can move downwards to make slight contact with the LED bead 18 and then move upwards to detach from the contact. When contacting the LED bead 18, it will slightly press down on the LED bead 18, allowing the LED bead 18 to make better contact with the solder paste. Because the air blower 18 blows air downwards, an air film is formed between the bottom of the air blower 18 and the LED bead 18, making it easier for the air blower 18 to detach from the LED bead. The air blower 6 will not stick to the solder paste, resulting in a better soldering effect between the solder paste and the LED bead 18. The LED bead 18 and the solder paste are more stably fixed together, and the soldering is stronger. If the air blower 6 is worn, it can be directly replaced, which is very convenient.

[0032] Of course, the above-described embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of the claims of this utility model.
