It is suitable for welding irregularly shaped surfaces with small welding surfaces on automotive upper frame trim strips.

[0032] This application uses the welding of automotive upper frame trim strips as an example to introduce the structure and usage of the welding equipment described herein. The welding equipment provided in this application is not only suitable for welding automotive upper frame trim strips, but also for welding applications of other products, specifically:

[0033] Please refer to Figure 1-6A welding device includes a worktable 1, and an accessory fixing component 2, an accessory placement component 3, a gripping mechanism 4, and a welding component 5 disposed on the worktable 1. The worktable 1 has a welding area; the accessory placement component 3 is disposed on one side of the welding area; the fixing end of the accessory fixing component 2 is disposed opposite to the welding area for contact with the accessory; the gripping end of the gripping mechanism 4 is movably disposed above the accessory fixing component 2 and the accessory placement component 3; the welding component 5 is vertically and vertically disposed opposite to the welding area. By setting the accessory fixing component 2, accessory placement component 3, gripping mechanism 4, and welding component 5 on the worktable 1, the gripping mechanism 4 can automatically grip the accessory placed on the accessory placement component 3, place the accessory in a predetermined welding position where it is fixed by the accessory fixing component 2, and then lower the welding component 5 to the predetermined welding position to weld the workpiece and the accessory. This replaces manual attachment and welding, thereby improving the welding quality of the product.

[0034] In some embodiments, the accessory placement assembly 3 includes a support base 31 and an abutment piece 32; the support base 31 has a placement groove on the side away from the worktable 1; one end of the abutment piece 32 is connected to the support base 31, and the other end of the abutment piece 32 is used to abut against the lower surface of the accessory. By providing a placement groove on the support base 31, and after the accessory is placed in the placement groove, the bottom of the accessory is abutted by the abutment piece 32, that is, the bottom of the accessory is not completely in contact with the placement groove, leaving a gripping space for the gripping mechanism 4, thereby enabling the accessory to be gripped effectively.

[0035] In some embodiments, the accessory placement assembly 3 includes at least two sets of support bases 31; the gripping mechanism 4 includes at least two grippers 41; the grippers 41 are movably disposed above the support bases 31.

Furthermore, by cooperating with multiple welding electrodes, multiple accessories can be welded simultaneously, thereby improving welding efficiency.

[0036] In some embodiments, the accessory fixing assembly 2 includes at least two opposing fixing seats 21; each fixing seat 21 is provided with a fixing piece 22, and there is a gap between the opposing fixing pieces 22; the welding assembly 5 is vertically movable and positioned opposite the gap. By providing opposing fixing pieces 22 on the two fixing seats 21, that is, the two fixing pieces 22 can respectively press and fix the two ends of the accessory, thereby improving the fixing effect of the accessory; at the same time, the gap between the fixing pieces 22 allows the welding electrode of the welding assembly 5 to contact the accessory through the gap, thereby realizing the welding of the accessory and the workpiece.

[0037] In some embodiments, the welding assembly 5 includes a lifting member 51 and an electrode member 52; the movable end of the lifting member 51 is kinetically connected to the electrode member 52; the welding end of the electrode member 52 faces the welding area.

[0038] In some embodiments, the electrode 52 includes an upper electrode 521 and a lower electrode 522 disposed opposite to each other, and the upper electrode 521 and the lower electrode 522 are respectively disposed on both sides of the welding area in the vertical direction. By disposing the upper electrode 521 and the lower electrode 522 on the upper and lower sides of the welding area respectively, when the upper electrode 521 and the lower electrode 522 are connected to the workpiece through an accessory, the heat generated by the current will melt and bond the accessory and the workpiece at the connection point, thereby achieving a welding effect.

[0039] In some embodiments, a workpiece fixing assembly 6 is further provided on the worktable 1; the side of the workpiece fixing assembly 6 away from the worktable 1 forms a contour support surface; the fixing end of the accessory fixing assembly 2 is movably disposed above the contour support surface. By providing the workpiece fixing assembly 6 and forming the contour support surface, the workpiece to be welded can be effectively supported and fixed.

[0040] In some embodiments, the workpiece fixing assembly 6 includes at least two sets of contouring supports 61; all contouring supports 61 are spaced apart, and the supporting surfaces of all contouring supports 61 form contouring support surfaces. By providing multiple sets of contouring supports 61, different contouring supports 61 can be used according to different workpiece shapes, so that the formed contouring support surfaces can more effectively fit the workpiece and play a more effective supporting and fixing role.

[0041] In some embodiments, at least two contouring supports 61 have different heights. By using contouring supports 61 of different heights, multiple contouring supports 61 can form an arc-shaped contouring support surface, making it suitable for workpieces of more shapes.

[0042] In some embodiments, the support surface of the contour support 61 is provided with a fixing block 62. By providing the fixing block 62 on the support surface, the fixing block 62 fixes the workpiece on the support surface, thereby improving the stability of the workpiece on the contour support 61.
