Plastic oil tank internal welding device

Abstract

The invention relates to the technical field of plastic oil tank manufacturing equipment, in particular to a plastic oil tank internal welding device. The welding device includes a supporting platform, mechanical hands arranged on the supporting platform and a 6-axis linkage supporting arm. The 6-axis linkage supporting arm is connected to the supporting platform. The mechanical hands include a heating head equipped first mechanical hand and a clamp equipped second mechanical hand. The first mechanical hand and the second mechanical hand are in slip connection with the supporting platform. The orientation of the first mechanical hand and the orientation of the second mechanical hand are both parallel to the plane where the supporting platform is located. The first mechanical hand and the second mechanical hand have the same orientation, which is clockwise or counterclockwise along the rotation direction of the supporting platform. The supporting platform is also provided with a heating unit for heating weldments. The welding device provided by the invention has small space occupation, is flexible and convenient to process, and also can guarantee the welding efficiency at the same time.

Description

technical field [0001] The present application relates to the technical field of plastic fuel tank manufacturing equipment, in particular to a plastic fuel tank internal welding device. Background technique [0002] Most of the early automobile fuel tanks were metal fuel tanks. Due to the many defects of metal fuel tanks in terms of environmental protection and safety performance, this led to the birth of plastic fuel tanks. Plastic fuel tanks are light in weight, strong in anti-corrosion, will not explode due to thermal expansion, and have high safety. Plastic fuel tanks are usually blow-molded at one time, and the shape is random. It can be formed into a suitable shape according to actual needs, and the production cost is low and the processing technology is simple. , no matter how complicated the product shape is, it can be formed at one time, and the scrapped products can be recycled after being crushed. These advantages are incomparable to metal fuel tanks. It is precis...

AI Technical Summary

Problems solved by technology

It can be seen that when welding a plastic fuel tank, it needs to be heated first and then placed for welding, and the general equipment can only be equipped with a single welding head, so the welding head needs to be replaced. When the welding head needs to be replaced, it is often necessary to manually replace the welding head to continue the welding work. The replacement operation process is complicated and cumbersome, and needs to be replaced every time welding, resulting in low processing efficiency. In order to avoid frequent replacement of welding heads, it is necessary to equip two 3D robot arms at the same time. Because the 3D robot arms themselves are powerful and complex in structure The characteristics of the equipment lead to high cost. Equipping two such equipment at the same time not only costs a lot, but also takes up a lot of space, which brings inconvenience to production management and maintenance.
