Description

Seam welder electrode debugging tool

Technical Field

The utility model relates to the technical field of seam welders, in particular to a seam welder electrode debugging tool.

Background

Seam welder is a device for aligning and packaging a tube shell and a cover plate in the fields of optical communication and the like. As shown in fig. 2, the seam welder is provided with a Y-direction moving table 100, a turntable 200 and two sets of electrodes, the turntable 200 is mounted on the Y-direction moving table 100, the turntable 200 can move in the Y-direction under the driving of the Y-direction table, the turntable 200 is provided with positioning pins 300 for positioning a clamp, wherein the connecting line of the two positioning pins 300 is parallel to the Y-axis of the seam welder and passes through the center of the turntable 200, each set of electrodes comprises an electrode mounting block 400, an electrode shaft 500 and an electrode wheel 600, the electrode mounting block 400 is provided with an electrode hole, the electrode shaft 500 is inserted in the electrode hole, the electrode wheel 600 is fixed on the electrode shaft 500, and the two electrode wheels 600 are used for simultaneously welding products. In the installation, the product fixture is placed on the turntable 200, the fixing is completed by inserting the positioning pins 300 into the positioning pin holes of the fixture, and then the product is placed in the fixture to complete the fixing. During welding, the left and right electrode wheels 600 move towards the center direction according to the length and width dimensions of the tube shell, when the left and right electrode wheels 600 move right and left sides of the tube shell, the electrode wheels 600 move downwards until the electrode wheels 600 contact the cover plate with preset pressure, and then the Y-direction moving workbench 100 drives a product to move in the Y direction, so that welding of the long sides of the tube shell is completed; and then the turntable 200 rotates 90 degrees to enable the short side of the tube shell to be positioned in the Y direction, and welding of the short side of the tube shell is completed. If the electrode wheel 600 is not coaxial in the Y direction, the cover plate is likely to be rubbed when being pressed down, so that deviation occurs after the cover plate tube shell is aligned; if the electrode wheels 600 are not coaxial in the Z direction, the pressure is easy to be high while the pressure is low, so that the seam welding effect of the left electrode wheel 600 and the right electrode wheel 600 is greatly different; only if the axes of the left and right electrode wheels 600 are completely coincident, the quality of the seam welded product after encapsulation can be ensured. In the Z direction, as two Z-direction modules are arranged, the coaxiality of the electrode wheel can be ensured by adjusting the origins of the two Z-direction modules; however, in the Y direction, the coaxiality of the left electrode and the right electrode in the Y direction can be ensured only through a copper pad or other cushion blocks.

In the prior art, the positions of the two electrode wheels in the Y direction and the Z direction are generally adjusted by naked eyes, and then the coaxiality of the left electrode wheel and the right electrode wheel is ensured. This approach is not only time consuming and laborious, but also has low accuracy.
