Automatic welding line for LED tube

Abstract

An automatic welding line for an LED tube comprises a tube transfer assembly and a laser welding assembly; the tube transfer assembly comprises a chain conveyor mechanism and locating transfer blocksarranged on a conveyor chain in the chain conveyor mechanism, and LED tubes are driven to convey by the conveyor chain through the locating transfer blocks; the laser welding assembly comprises laserwelding mechanisms arranged on one side or the both sides of the chain conveyor mechanism; each laser welding mechanism comprises a laser welding component and a welding locating component; the laserwelding component comprises a laser welding joint; the welding locating component comprises transparent pressing blocks and a pressing locating cylinder, and the LED tubes are located and pressed on the locating transfer blocks by the transparent pressing blocks in the pressed state at least; and in work, laser penetrates the transparent pressing blocks for welding the corresponding LED tubes. Theautomatic welding line has the characteristics of reliable performance, high automation degree, low labor cost, and high welding efficiency and welding quality; and connection of plastic cases of theLED tubes through a laser welding technology is pioneered in the industry.

Description

technical field [0001] The invention relates to an automatic welding line, in particular to an automatic welding line for LED lamp tubes. Background technique [0002] In the prior art, the connection operation of the plastic shell of the LED lamp tube generally adopts the method of pasting and connecting with glue. This connection method has the following disadvantages: 1. The glue used is a chemical substance with a certain volatility, resulting in a pungent smell , working for a long time will cause the operator to feel uncomfortable, affect their health, and easily suffer from occupational diseases; 2. The glue used is a chemical product, which will pollute the ecological environment when it is improperly operated or leaks; 3. Artificial use of glue for LED When the plastic shell of the lamp tube is connected, the glue is easy to seep out of the surface, which directly affects the appearance of the LED lamp tube; 4. If the glue is applied unevenly, it will directly affec...

[0002] In the prior art, the connection operation of the plastic shell of the LED lamp tube generally adopts the method of pasting and connecting with glue. This connection method has the following disadvantages: 1. The glue used is a chemical substance with a certain volatility, resulting in a pungent smell , working for a long time will cause the operator to feel uncomfortable, affect their health, and easily suffer from occupational diseases; 2. The glue used is a chemical product, which will pollute the ecological environment when it is improperly operated or leaks; 3. Artificial use of glue for LED When the plastic shell of the lamp tube is connected, the glue is easy to seep out of the surface, which directly affects the appearance of the LED lamp tube; 4. If the glue is applied unevenly, it will directly affect the connection effect and shorten the service life of the LED lamp tube; 5. Use glue The way of connection, after a long time of use, the glue cured product will have physical changes or chemical changes, which will directly affect the connection effect and shorten the service life of the LED tube

This structural welding system can only be applied to the welding of guide wires and power boards, but not to the connection of plastic shells, and the use of laser welding technology to connect plastic shells of LED lamp tubes is still in a blank stage in this industry
