[0016] Working principle: When performing welding operations, the operator stands in front of the operating table and controls the operation of the equipment through the operating lever and operating buttons. After the equipment is started, the motorcycle speed change pedal is first sprayed and washed by the water sprayer, and then dried and clamped by the clamping arm into the sandblasting tank for sandblasting. The sand particles are pushed by the air pump through the sand outlet pipe and sprayed on the surface of the object by the sandblaster. After completion, it is clamped by the clamping arm to the conveyor belt, clamped by the clamping plate 1 and the clamping plate 2, and conveyed by the conveyor belt to the designated position for welding. During welding, the welding gun changes its position under the drive of the welding arm, and the wire feeding mechanism sends the welding wire from the wire collecting drum 2, passes through the limit tube 2 and the wire feeding wheel, and is sent to the wire feeding tube of the welding gun by the wire feeding tube. The laser beam emitted by the welding gun contacts the welding wire, generating high-temperature melting, and welding the two parts of the motorcycle speed change pedal together. At the same time, water pump 1 pumps out water from water tank 1 and sends it to the cooling pipe of the welding gun through water outlet pipe 1 to cool the welding gun and prevent it from overheating. Air pump 3 pumps out the protective gas from the gas tank and sends it to the air inlet pipe of the welding gun through the air outlet pipe to provide protective gas for welding. The excess welding wire generated during welding is concentrated in the recovery cylinder under the action of the scraper. After receiving the hot water from the water outlet pipe of the welding gun, the hot water flows into the evaporator to generate water vapor. The water vapor flows through the generator through the evaporation pipe and then enters the condenser to form two nodes, one hot and one cold. Based on the Seebeck effect, when the connection point of two different metals or semiconductors is at different temperatures, an electromotive force will be generated at the connection point, thereby forming an electric current. The heating pipe outside the recovery cylinder generates a turbine effect under the action of the current of the power generation device, which will heat the welding wire in the recovery cylinder to soften it for easy recycling. The softened welding wire will flow into the molding tube under the action of gravity. After the welding wire in the plastic tube enters the small hole opened on the wire collecting drum one, the motor one drives the wire collecting drum one to rotate, and the welding wire is wound on the wire collecting drum one to complete the recycling of the welding wire. The excess sand particles generated when the motorcycle speed change pedal is sandblasted enter the collecting box one through the holes of the sandblasting slot, and then the sand particles flow through the magnetic pipe under the action of gravity. The magnetic pipe will adsorb the iron-containing sand particles in the sand particles on the inner wall of the pipe. After the remaining sand particles enter the cyclone separator one, the magnetism is released, and the iron-containing sand particles enter the collecting box two through the discharge pipe one. The sand particles entering the cyclone separator one, the cyclone separator one separates the sand particles with a diameter of 300mm through wind force, and enters the collecting box two through the discharge pipe two, and the remaining sand particles enter the cyclone separator two. The cyclone separator two separates the sand particles with a diameter of 200mm through wind force, and enters the collecting box two through the discharge pipe three, and the remaining fine sand enters the collecting box two through the discharge pipe four. Air pump 2 in collection box 2 will send the sand back to the sand storage tank through the sand return pipe to complete the recycling of the sand. During the welding process, the operating table will display the operating status, various parameters and related information of the equipment. The operator can control the equipment through the operating lever and operating button. The operating button can immediately stop the equipment operation in case of emergency to ensure safety.

[0017] The present invention provides a laser welding device for a motorcycle speed change pedal. It has the following beneficial effects: 1. The present invention can re-melt and cool the discarded welding wire into new welding wire through the joint action of the recycling mechanism and the power generation device, thereby reducing the waste of welding wire. In addition, the recycling of welding wire can reduce the demand for raw materials and alleviate resource pressure.

[0018] 2. The present invention, through the joint action of the cooling mechanism, the recovery mechanism and the power generation device, can convert the waste heat generated during welding into electrical energy through the power generation device, thereby realizing the recovery and utilization of redundant heat, improving energy utilization efficiency and reducing energy waste.

[0019] 3. The present invention can separate and recycle commonly used sand particles through the action of the separation mechanism, magnetic force and wind force. With the assistance of the air pump and the pipeline, the sand particles can be reused, reducing the demand for new sand particles, promoting the recycling of sand particle resources, and forming a virtuous circle.
