Device and method for detecting welding of automobile accessories

Abstract

The invention discloses a device and a method for detecting welding of automobile accessories. The device comprises a welding structure, a jig structure, a jacking structure, a fixing frame, fixing blocks and a cooling structure; the jig structure is arranged at the lower end position of the welding structure; the jacking structure is arranged at the lower end position of the jig structure; the fixing frame is arranged on the outer side position of the jacking structure; the fixing blocks are arranged on the inner side position of the fixing frame, one ends of the fixing blocks are fixed to the fixing frame, and the other ends of the fixing blocks are fixed to the jacking structure; and the cooling structure is arranged at the lower end of the jig structure and the inner position of the jacking structure. According to the device and the method, a temperature sensor is arranged between the welding structure and the jig structure, a pressure sensor and the temperature sensor are arrangedon cooling tongs, so that the situation that product welding is poor or the welding position is shifted due to the fact that the welding temperature is too high and the pressure of the cooling tongsis too large in the welding combination technology process is effectively avoided.

Description

Technical field [0001] The invention relates to a detection device and method, in particular to a welding detection device and method for automobile parts. Background technique [0002] The welding bonding process has been widely used in industries such as electronics, automobiles, and household appliances. Welding can combine two pieces of the same material, such as metal or plastic, or combine different materials, such as metal and plastic. The welding process can include many forms, including arc welding, oxygen fuel welding, resistance welding, electroslag welding, laser beam welding, etc. Its resistance welding has the advantages of simple operation, easy mechanization and automation, and high productivity. It is widely used in automobile parts. Manufacturing Industry. [0003] In the process of welding different materials, part of the material is metal and part of the plastic is plastic. If the temperature cannot be effectively controlled during the resistance welding proce...

AI Technical Summary

Problems solved by technology

[0003] In the process of welding different materials, because part of the material is metal and part is plastic, if the temperature cannot be effectively controlled during the resistance welding process, it is easy to soften the plastic product material, and the softened plastic product is grasped by the cooling gripper. Excessive grasping pressure during the process will cause deformation of the plastic material product, resulting in defective welded products after welding and cannot be used
