Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a fully automatic welding equipment suitable for welding fixed frames such as LED lighting lamps, liquid crystal television displays, solar silicon wafers or doors and windows. Background technique [0002] At present, most of the external fixing frames used in equipment such as LED lighting, LCD TV monitors, solar silicon wafers or doors and windows are aluminum frames, and the aluminum frames are generally processed by manual welding or automatic welding. [0003] When manually welding the aluminum frame, the operator usually needs to complete the splicing of the adjacent aluminum strips first, and then weld the joint of the aluminum strips with a welding torch. The operator will damage the aluminum strips if he is not careful during the welding process. Therefore, the manual welding frame technology The skill requirements are relatively high. Generally, s...

Problems solved by technology

[0003] When manually welding the aluminum frame, the operator usually needs to complete the splicing of the adjacent aluminum strips first, and then weld the joint of the aluminum strips with a welding torch. The operator will damage the aluminum strips if he is not careful during the welding process. Therefore, the manual welding frame technology The skill requirements are relatively high. Generally, skilled masters are required to train new operators for a period of time before they can take up the job. The long training time cannot meet the company's needs for the candidates to take up the job immediately; moreover, some toxic Substances, such as: acetaldehyde, rosin acid, sulfide, isocyanate, nitrogen oxides, etc., and fly in the air, these toxic substances are easy to invade the human liver, lungs, cardiovascular and blood through the respiratory tract, welding process α, β, and γ rays will also be produced in the welding process, and these radioactive substances will accumulate in the body in a small amount. Therefore, the toxic and radioactive substances produced during the manual welding process may endanger the health of the operators and cause some occupational diseases of the operators. occur

The above situation usually leads to a shortage of operators in this position of the enterprise, and the production capacity of the enterprise is tight

At the same time, the manual welding operation is cumbersome, the work efficiency is low, and it cannot meet the batch development trend of related products of the enterprise; the error caused by manual welding is also large, which will cause unstable product quality

[0004] Therefore, the inventors of this case and other companies have invented some automatic welding equipment, which generally realize the welding of multiple points of the aluminum frame by controlling the movement of the welding torch by the manipulator or track. This way of switching welding points not only makes the manipulator or The structure of the track is complex and takes up a lot of space, which makes the volume and cost of the equipment high, and the efficiency is low; moreover, the welding torch on this type of automatic welding machine can only weld in the plane direction during welding, which is not suitable for the needs. The workpieces welded by the circular seam are welded; moreover, due to the limitation of the fixture structure, it is not suitable for workpieces of different shapes or sizes. Generally, it is a special welding machine for a certain type of product, and different welding equipment needs to be used for welding different workpieces. Replacing the fixture that matches the workpiece has poor versatility, resulting in reduced welding efficiency and increased production costs
