With the introduction of new products and special process requirements, LED lamp pins and wires also need to use heat shrink tubing. In the early stages of the product, we used hot air guns manually, but as the order volume increased, the efficiency of manual hot air gun operations was too low and the order volume could not be completed.

[0010] As a further improvement of the above technical solution, the first carrier includes a first fixed plate, which is rotatably connected to a pressure plate, and a receiving groove is provided on the fixed plate. When the pressure plate rotates to the top of the first fixed plate, it covers the receiving groove.

[0011] As a further improvement of the above technical solution, the second carrier includes a second fixing plate, a plurality of support blocks are arranged on the second fixing plate, and each support block is provided with a slot for placing the wire.

[0012] As a further improvement of the above technical solution, the air outlet of the hot air gun is a strip-shaped air outlet, and the length of the strip-shaped air outlet is greater than the distance between two adjacent first carriers or second carriers.

[0027] In this embodiment, the LED lamp pins 001 and wires 002 equipped with sleeves are manually loaded onto multiple carriers one after another, and the conveying and loading are carried out through the conveying mechanism 2. After the carrier moves to the bottom of the hot air gun 9, the hot air blown out of the air outlet of the hot air gun 9 heats the position (heat shrinkage position) on the LED lamp pins 001 and the wires 002 where the sleeves are installed, so that the sleeves are heat-shrunk on the LED lamp pins 001 and the wires 002, wherein the hot air blows through the sleeves and is sucked away by the exhaust fan 10. Then, after the sleeves are heat-shrunk, the LED lamp pins 001 and the wires 002 are moved to the bottom of the cooling fan for cooling, and then move to the lower side of the conveyor belt with the conveyor belt, and fall downward into the feeding trough 6 under the action of gravity for easy collection. Compared with the manual operation of heat shrinking the sleeves with the hot air gun 9, the utility model realizes automatic sleeve heat shrinkage through the conveying mechanism 2, which greatly improves the work efficiency and product quality, and also reduces the labor intensity.

[0028] In this embodiment, refer to Figure 3 and Figure 4The conveyor belt includes a chain assembly 21 and a motor 22. The chain assembly 21 includes a chain 211, a driving sprocket 215 and a driven sprocket 212. The driving sprocket 215 is connected to a driving sprocket center shaft 216. The two ends of the driving sprocket center shaft 216 are respectively installed on the frame 1 through a bearing seat 214. Similarly, the driven sprocket 212 is connected to a driven sprocket center shaft 213. The two ends of the driven sprocket center shaft 213 are also respectively installed through a bearing seat 214 is installed on the frame 1, so that the installation of the driving sprocket 215 and the driven sprocket 212 is realized, and the rotation of the driving sprocket 215 and the driven sprocket 212 is realized based on the bearing seat 214, the chain 211 is connected between the driving sprocket 215 and the driven sprocket 212, and the motor 22 is connected to the driving sprocket center shaft 216. The motor 22 drives the driving sprocket center shaft 216 to rotate, thereby driving the driving sprocket 215 to rotate, that is, realizing the conveying function of the chain 211.

[0029] Furthermore, the motor 22 is installed on the frame 1, and a belt drive, a chain drive or a gear drive is adopted between the output shaft of the motor 22 and the central axis of the driving sprocket 215. In this embodiment, a chain drive is selected, that is, a driving sprocket 23 is arranged on the main shaft of the motor 22, and a transmission sprocket 217 is arranged on the central axis 216 of the driving sprocket. A transmission chain is connected between the driving sprocket 23 and the transmission sprocket 217, and power is transmitted through the chain drive, thereby driving the conveyor belt to run to realize the conveying function.

[0030] In this embodiment, refer to Figure 4 The carrier includes a first carrier 218 and a second carrier 219. The first carrier 218 is used to load the LED lamp pin 001, and the second carrier 219 is used to load the wire 002. A plurality of the first carriers 218 and the second carriers 219 are alternately arranged on the chain 211 at the same intervals.

[0031] Specifically, refer to Figure 5The first carrier 218 includes a first fixing plate 2181, and a pressing plate 2183 is rotatably connected to the first fixing plate 2181. Furthermore, a hinge groove 2182 is provided on the first fixing plate 2181, and a hinge block 2184 is provided on the pressing plate 2183. The hinge block 2184 is rotatably connected in the hinge groove 2182 through a hinge shaft 2185. A receiving groove is provided on the fixing plate, and the pressing plate 2183 covers the receiving groove when it rotates to the top of the first fixing plate 2181. That is, the worker puts the head of the LED lamp in the receiving groove, and then turns over the pressing plate 2183 to press the head of the LED lamp, which can not only fix the head of the LED lamp, but also protect it. After the head of the LED lamp is fixed, it is equivalent to fixing the LED lamp pin 001, and the loading work of the LED pin 001 is completed. The part of the LED lamp pin 001 with the sleeve is located outside the first fixing plate 2181, which is convenient for the operation of hot air heat shrink sleeve. When the first carrier 218 moves to the lower side of the chain 211, that is, the first fixed plate 2181 is in an inverted state, the pressing plate 2183 rotates to a vertical state under the action of gravity, and the LED lamp breaks away from the receiving groove and falls downward, thereby realizing the unloading of the LED pins. The first carrier 218 continues to move to the loading position to load new LED pins, thereby realizing the continuous sleeve heat shrinking operation of the LED pins.

[0032] Specifically, refer to Figure 6 The second carrier 219 includes a second fixed plate 2191, on which three support blocks 2192 are arranged, and each support block 2192 is provided with a slot 2193 for placing the wire 002, wherein a heat shrinking station is formed between two adjacent support blocks 2192, and the portion of the wire 002 equipped with the sleeve is in the heat shrinking station, and a notch 2194 is arranged on the second fixed plate 2191 below the heat shrinking station, and hot air blows the wire 002 to achieve the sleeve heat shrinking operation and then flows out from the notch 2194. When the second carrier 219 moves to the lower side of the chain 211, that is, the second fixed plate 2191 is in an inverted state, the wire 002 will fall downward under the action of gravity, and the unloading work of the wire 002 is realized, and the second carrier 219 continues to move to the loading position to load new wire 002, and the continuous sleeve heat shrinking operation of the wire 002 is realized.

[0033] In this embodiment, the air outlet of the hot air gun 9 is a strip-shaped air outlet, and the length of the strip-shaped air outlet is greater than the spacing between two adjacent first carriers 218 or second carriers 219, that is, when the rear first carrier 218 enters under the hot air gun 9 to perform sleeve heat shrinkage, the front first carrier 218 is still under the hot air gun 9 to perform sleeve heat shrinkage, and the sleeve heat shrinkage of the wire 002 is the same as above. In this way, in the process of transporting the LED pins and the wire 002 on the conveyor belt, the sleeve heat shrinkage time is increased, thereby improving the quality of the sleeve heat shrinkage.

[0034] In this embodiment, refer to Figure 3 The exhaust fan 10 includes an exhaust opening 101 and an exhaust pipe connection port 102. The exhaust pipe connection port 102 is connected to the exhaust pipe. The exhaust opening 101 is located directly below the hot air gun 9, so as to extract the hot air after the sleeve is heat-shrunk to prevent the hot air from flowing randomly and affecting the sleeve heat shrinkage operation. The extracted hot air is discharged from the exhaust pipe.

[0035] In a preferred embodiment, reference Figure 1 and Figure 2 The frame 1 is provided with a first protective cover 3 and a second protective cover 4. The first protective cover 3 can cover the conveying mechanism 2, and the second protective cover 4 can cover the hot air gun 9, thereby playing a protective role and improving the safety during the heat shrinking operation of the sleeve.

[0036] In a preferred embodiment, reference Figure 1 and Figure 2 The bottom of the frame 1 is provided with self-locking casters 7 and foot cups 8. The self-locking casters 7 facilitate the movement and transportation of the equipment, and the foot cups 8 improve the stability of the equipment after being placed.
