[0034] The working principle of the above-mentioned cap beam frame welding positioning system is:

[0035] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0036] Second, when preparing for positioning, the main controller 5 controls the CNC slide 1 and the main robot 2 to drive the end assembly 3 and the visual assembly 4 to move and approach the welding point. During this process, the heat-insulating shell 42 and the industrial camera 45 are driven by the auxiliary robot 41 and the CNC slide 1 to scan the assembly of the skeleton piece along the way and check whether the wedge block used for positioning is missing;

[0037] Third, the main robot arm 2 then drives the end assembly 3 to adjust its position, and drives the bevel gear set 386 to mesh transmission through the servo motor 387, and supplies energy to the first coil ring 36 and the second coil ring 385 through the joint controller 39, so that the bevel gear set 386 is transmitted, and the lower gear of the bevel gear set 386 is meshed with the toothed disc 37 to rotate accordingly, and under the energized adsorption action of the first coil ring 36, the linkage body 34, the screw hole seat 381 and the screw rod 382 are driven to follow the toothed disc 37 on the end fixed seat 31 for angle adjustment, and the angle adjustment data of the linkage body 34 is detected here by the optical sensor between the optical sensor assembly 33 and the detection aperture 35, and then the main robot arm 2 drives the end assembly 3 to the welding point and the appropriate height, and at this time, the end fixed seat 31 and the angle adjustment member 38 are kept vertical to the assembly platform;

[0038] Fourth, the bevel gear on the top side of the bevel gear set 386 rotates under the transmission action of the servo motor 387 and the bevel gear set 386, and drives the limiting sleeve 384 to rotate accordingly under the adsorption of the second coil ring 385.

During the welding process, the spacing between the two layers of the multi-layer filter 46 is adjusted by adjusting the cylinder 44 to reduce the influence of ambient light on the industrial camera 45 and improve the image data acquisition effect of the industrial camera 45.

[0039] The present invention provides an improved cap beam skeleton piece welding positioning system, which can adapt to welding gun heads of different specifications by setting a primary adjustment structure of the main robot arm 2 and a secondary adjustment structure of the terminal component 3. The high-precision adjustment action of the terminal component 3 can also overcome the precision error phenomenon existing in the conventional main robot arm 2. The visual component 4 is set to reduce the influence of ambient light on the industrial camera 45, thereby improving the image data acquisition effect of the industrial camera 45.
