Description

Technical Field

[0001] The invention relates to the field of welding robots, in particular to a precise guided real-time automatic deviation correction intelligent welding robot workstation. Background Art

[0002] Welding is also called fusion or melting. Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. Welding robots are industrial robots engaged in welding. Welding robots are currently widely used in various manufacturing industries, such as welding of automobile chassis, seat frames, guide rails, mufflers and torque converters, especially in the welding production of automobile chassis.

[0003] Current welding robots are generally composed of welding brackets, welding equipment and control systems.

[0013] Working principle: When the welding workstation is in use, the workpiece to be welded is first placed on the upper end of the clamping table of the auxiliary fixing mechanism. At this time, the lower pressing block on the upper end of the clamping table is squeezed by gravity to cause it to move downward. During the downward pressing process, the lower pressing block will generate a thrust on the pull rod at the lower end, causing the pull rod to move downward into the inflatable tube to form a downward push-pull. At this time, the internal air pressure changes, and the gas inside the inflatable tube is filled into the connecting tubes on both sides to make it merge into the outer rods on both sides. The air pressure inside the outer rod changes, causing it to push the inner rod outward, thereby changing the spacing between the clamps on both sides to achieve a quick clamping and fixing effect on the workpiece to be welded; After the auxiliary clamping and fixing of the workpiece to be welded is completed, the second connecting block with the outer thread sleeve can be driven to move horizontally, thereby changing the horizontal position of the upper back plate, the guide plate and the welding assembly on the back plate, and then the vertical screw on the back plate can be driven to complete the vertical movement of the first connecting block with the outer thread sleeve, thereby realizing the vertical height adjustment of the welding assembly installed at the front end of the first connecting block, and at the same time, the electric push rod can be used to push the slider at the extension end to drive the upper back plate to adjust the position in the front and rear directions, thereby realizing the front and rear position adjustment of the welding assembly; After completing the adjustment of the overall position of the welding assembly, the welding head is used to perform welding operations on the workpiece to be welded. Since the welding head adopts a control chip based on the synchronous dual-rotating laser arc sensor current tracking and real-time correction method to control the welding, when the welding head is found to be offset, it can quickly perform automatic correction processing, that is, the control chip controls the No. 1 rotating motor, the No. 2 rotating motor and the No. 3 rotating motor to realize multi-directional rotation fine-tuning of the welding head.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

At this time, the rotation of the transverse screw 7 drives the No. 2 connecting block 11 with the outer threaded sleeve to undergo lateral displacement. Since the No. 2 connecting block 11 is slidably set in the transverse groove 8 and the transverse groove 8 restricts it from rotating, the lateral displacement is achieved; and the No. 2 servo motor drives the vertical screw 1 on the back plate 2 to complete the vertical movement of the No. 1 connecting block 10 with the outer threaded sleeve, thereby achieving the vertical height adjustment of the welding assembly 3 installed at the front end of the No. 1 connecting block 10.

At this time, the No. 1 gear 3013 on the outer side of the No. 2 rotating shaft 3012 rotates and drives the meshing connected No. 2 gear 3014 to rotate, and the No. 2 gear 3014 is fixed on the No. 1 rotating shaft 3011. After the No. 1 rotating shaft 3011 rotates, it will drive the toggle plate 306 fixed on the outer side to flip, thereby completing the flip adjustment use of the welding head 309 at the lower end.

[0020] Reference Figure 8 The diameter of the first gear 3013 is one third of the diameter of the second gear 3014; when the first gear 3013 rotates, it can drive the second gear 3014 to rotate. At the same time, since the first gear 3013 with a smaller diameter drives the second gear 3014, the adjustment drive will not cause excessive false touches due to synchronous rotation.

The lower pressure block 501 will generate a thrust on the pull rod at the lower end during the downward pressing process, causing the pull rod to move downward into the inflation tube 509 to form a downward pressure push-pull. At this time, the internal air pressure changes, and the gas inside the inflation tube 509 is filled into the connecting tubes 504 on both sides to make it merge into the outer rods 503 on both sides. The air pressure inside the outer rod 503 changes, causing it to push the inner rod 508 to move outward, thereby changing the spacing between the clamps 502 on both sides to achieve a quick clamping and fixing effect on the workpiece to be welded.
