Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent welding, more particularly to an intelligent welding robot. BACKGROUND

[0002] With the increasing number of product types and the increasing demand for product quality, people's requirements for welding process are also increasing. Many products originally welded by manual work have gradually developed towards automation. In order to reduce labor costs and greatly improve production efficiency, most of the work of the existing welding production line can be completed by the cooperation of welding robots and positioners. However, problems still occur during the welding process of the welding robot, as follows: 1. When the welding robot performs a task, if the welding parameters are not properly set, such as too low current resulting in insufficient welding pool temperature, the molten metal cannot be completely distributed, thereby producing less slag, or the moving speed is too fast, which can cause the welding pool to be unable to fill up in time, the molten metal cannot completely solidify or cool down too early, affecting the generation of slag. 2. When the wire tension is too loose, the welding wire can not be stably sent to the welding area, which can easily cause uneven wire feeding, burning, unstable molten pool and other problems, which can cause uneven quality of the weld, and can easily form pores, cracks and other defects. Moreover, uneven wire tension can cause unstable load of the wire feeding motor, causing instability or failure of the robot operation system, and affecting the overall welding operation performance.

[0020] Wherein, the inner side of elastic spring 213 is fixedly connected with compression ring 221, the side of moving hammer 22 is fixedly connected with the inner side of compression ring 221, the side of moving hammer 22 is connected with the inner side of elastic spring 213, the top end of moving hammer 22 is fixedly connected with moving shaft 222, the top end of moving shaft 222 is fixedly connected with fixed lug 223, the inner side of fixed lug 223 is connected with work type rod 232, the side of work type rod 232 is connected with moving rod 23, the side of moving rod 23 is provided with rotary groove 231, the side of fixed pipe 21 is fixedly connected with first motor 237.

[0021] The bottom end of the first motor 237 is fixedly connected with the top end of the first rotating rod 236, the side surface of the first rotating rod 236 is connected with the fixed disc 235, the side surface of the fixed disc 235 is fixedly connected with the inner side of the fixed tube 21, the top end of the first rotating rod 236 is fixedly connected with the rotating shaft 233, the side surface of the rotating shaft 233 is provided with the rotating clamping groove 234, and the inner side of the rotating clamping groove 234 is connected with the inner side of the rotating groove 231.

[0022] The welding wire 5 needs to be consumed on the inner side of the installation groove 103, and is changed in direction through the guide pipe 105 and the steering wheel 107. The top end edge of the steering wheel 107 is flush with the center point of the guide pipe 105, and the side surface edge of the steering wheel 107 is flush with the center point of the rotating rod 108. An annular groove is formed in the surface of the steering wheel 107, so that the sliding of the welding wire 5 on the steering wheel 107 can be fixed. The movement of the welding wire 5 is the effect of multiple components acting at the same time, so the connecting plate 109 connected to the side surface of the rotating rod 108 can make the welding wire 5 at the bottom end thereof act synchronously with the de-welding mechanism 2 on the side surface of the connecting plate 109. The welding wire 5 is welded in front, and the de-welding mechanism 2 de-welds the slag behind. When the first motor 237 is started, the first rotating rod 236 is driven to rotate, and the fixed disc 235 is fixed on the inner side of the fixed tube 21. The rotating shaft 233 is driven to rotate around the first rotating rod 236 through the rotation of the fixed disc 235. Therefore, the moving hammer 22 is driven to move in the inner side of the fixed tube 21 through the moving rod 23 during the rotation of the rotating shaft 233. The compression ring 221 fixed on the side surface of the moving hammer 22 is clamped in the middle of the elastic spring 213. The dragging of the moving shaft 222 to the moving hammer 22 changes the elastic effect of the elastic spring 213, so that the effect of the compression ring 221 acting on the moving hammer 22 is more obvious. The hammering of the welding position is more rhythmic, but the striking force on the welding part is not so strong.

[0023] Referring to Figures 6 to 10 The side surface of the U-shaped plate 31 is provided with the fixed sliding groove 311, the inner side of the fixed sliding groove 311 is connected with the side surface of the U-shaped sliding plate 33, the inner side of the U-shaped plate 31 is provided with the T-shaped sliding groove 312, the inner side of the rotating disc 313 is provided with the rotating groove 314, the side surface of the connecting rod 343 is fixedly connected with the driving disc 34, the side surface of the driving disc 34 is fixedly connected with the second rotating rod 341, the top end of the second rotating rod 341 is fixedly connected with the third motor 342, and the bottom end of the third motor 342 is fixedly connected with the side surface of the installation groove 103.

[0024] The top end of the U-shaped sliding plate 33 is fixedly connected with the pressing plate 331, the top end of the pressing plate 331 is fixedly connected with the T-shaped guide rod 332, the top end of the pressing plate 331 is fixedly connected with the compression spring 333, the side surface of the T-shaped guide rod 332 is connected with the inner side of the compression spring 333, and the top end of the compression spring 333 is fixedly connected with the bearing plate 323.

[0025] The side of the bearing plate 323 is fixedly connected with a T-shaped sliding plate 324, the side of the T-shaped sliding plate 324 is connected with the inner side of the T-shaped sliding groove 312, the side of the bearing plate 323 is connected with the side of the T-shaped guide rod 332, the side of the bearing plate 323 is connected with a I-shaped auxiliary rod 32, the side of the I-shaped auxiliary rod 32 is connected with the inner side of the U-shaped plate 31, the top end of the U-shaped plate 31 is fixedly connected with a second motor 322, the bottom end of the second motor 322 is fixedly connected with a screw rod 321, and the side of the screw rod 321 is threadedly connected with the inner side of the bearing plate 323.

[0026] The tightening mechanism 4 comprises a first fixed bolt 41 and a linkage disc 42, the side of the linkage disc 42 is provided with a fixed through groove 422, the side of the first fixed bolt 41 is connected with the inner side of the fixed through groove 422, the inner side of the fixed through groove 422 is connected with the side of a second fixed bolt 411, the side of the first fixed bolt 41 is fixedly connected with a Z-shaped fixed rod 412, the side of the linkage disc 42 is fixedly connected with a fixed tooth 421, the side of the fixed tooth 421 is connected with the bottom end of the U-shaped plate 33, and the side of the first fixed bolt 41 is connected with the inner side of the accommodating groove 103.

[0027] The movement of the driving mechanism 3 is realized through the action effect between the welding wire 5 and the conduit 105. The welding wire 5 is in close contact with the inner side of the conduit 105, which means that the welding wire 5 is loose in the inner side of the conduit 105. The tension of the welding wire 5 will affect the welding process of the bottom end of the rotating rod 108. Therefore, the tension of the welding wire 5 needs to be kept at the same level. When the two are in contact, the third motor 342 is started. The third motor 342 drives the U-shaped plate 31 to rotate around the center point of the rotating disc 313. At the same time, the second motor 322 at the top end of the U-shaped plate 31 is also started to compress the U-shaped plate 33 on the side of the fixed tooth 421. The welding wire 5 wound around the side of the first fixed bolt 41 is tightened in the opposite direction, so that the tension reaches the required vertical position. Then, the rotation of the third motor 342 is stopped. The second motor 322 needs to move the bearing plate 323 to the top end of the T-shaped sliding groove 312, so that the U-shaped plate 33 is away from the fixed tooth 421, and the rotation of the welding wire 5 is continued to be released; The compression spring 333 is fixed between the load plate 323 and the pressing plate 331, when the load plate 323 is at the top end of the T-shaped sliding groove 312, the top end of the T-shaped guide rod 332 drives the pressing plate 331 to move upwards, so that the bottom end of the U-shaped sliding plate 33 is not in contact with the top end of the fixed tooth 421, at this time, the compression spring 333 is in a non-acting state, and the original length of the compression spring 333 is the length of the T-shaped guide rod 332, the load plate 323 is moved through the screw action of the screw rod 321, and the rotating force of the screw rod 321 is converted into the upward and downward movement by the work-type auxiliary rod 32; when the load plate 323 is at the bottom end of the T-shaped sliding groove 312, the bottom end of the U-shaped sliding plate 33 is connected with the side of the fixed tooth 421, at this time, the compression spring 333 is in a compressed state, and the U-shaped sliding plate 33 is pressed on the side of the fixed tooth 421 by the force applied to the pressing plate 331 by the compression spring 333, but when the U-shaped sliding plate 33 rotates with the rotation of the U-shaped plate 31, the U-shaped sliding plate 33 moves between different fixed teeth 421, and the connecting disc 42 is reversely rotated by the force between the U-shaped sliding plate 33 and the fixed tooth 421, so that the welding wire 5 is tightened.

[0028] The working principle of the present application is that the welding wire 5 at the bottom end of the rotating rod 108 is moved to the corresponding position for welding through the cooperation of the installation groove 103 and the cross rod 104, the welding wire 5 required is installed on the inner side of the installation groove 103, is passed out through the conduit 105, is turned through the steering wheel 107, and is then passed out from the rotating rod 108, since the welding process needs to consume the welding wire 5, the welding wire 5 is uniformly sent to the bottom end of the rotating rod 108 inside the supporting mechanism 1.

[0029] The top end of the connecting plate 109 fixedly connected to the side of the rotating rod 108 is provided with the removing welding mechanism 2, when welding is performed at the bottom end of the rotating rod 108, the moving hammer 22 connected to the other end of the connecting plate 109 can clean the welding slag at the welded place, the first rotating rod 236 is driven to rotate by starting the first motor 237, the rotating shaft 233 at the top end of the first rotating rod 236 rotates, the inner side of the rotating groove 231 is clamped by the rotating clamping groove 234 at the other end of the rotating shaft 233, and the two can rotate relative to each other, the fixed lug 223 is connected by the work-type rod 232 at the bottom end of the moving rod 23, so that the fixed lug 223 moves with the moving rod 23 in the rotating process of the first rotating rod 236, since the side of the moving hammer 22 is limited by the side of the elastic spring 213, the movement of the moving hammer 22 is in the vertical direction, meanwhile, the compression ring 221 fixed to the side of the moving hammer 22 is limited by the elastic spring 213, so that the compression ring 221 can only move inside the fixed baffle 211, and the side of the compression ring 221 is fixed in the middle of the elastic spring 213, and the force of the moving hammer 22 in the downward hitting is enhanced by the action of the elastic spring 213.

[0030] When the welding wire 5 is over-extended inside the conduit 105, the welding wire 5 needs to be tightened to make the welding material at the bottom end of the rotating rod 108 more uniform, so the welding wire 5 can be connected to the third motor 342 for starting after being in contact with the inside of the conduit 105, and the connecting rod 343 at the edge of the disc 34 drives the rotating disc 313 to rotate, in the normal operation process, the U-shaped plate 31 is in a horizontal position and does not interfere with the rotation of the first fixed bolt 41, when the U-shaped plate 31 rotates, the second motor 322 is started, and the bearing plate 323 is moved from the top end of the T-shaped sliding groove 312 to the bottom end of the T-shaped sliding groove 312, at this time, the compression spring 333 at the top end of the pressing plate 331 is in a compressed state, so the elastic potential energy accumulated inside the compression spring 333 acts between the pressing plate 331 and the bearing plate 323, and the bottom end of the U-shaped sliding plate 33 is clamped in the gap of the fixed tooth 421, which releases the welding wire 5 and blocks the welding wire 5; When the third motor 342 drives the rotating disc 313 to rotate, the first fixed bolt 41 rotates in the opposite direction to tighten the relaxed welding wire 5, when the welding wire 5 is not in contact with the inside of the conduit 105, the power supply of the third motor 342 is disconnected, the U-shaped plate 31 is stopped, and the bearing plate 323 is moved to the top end of the T-shaped sliding groove 312, so that the bottom end of the U-shaped sliding plate 33 moves away from the side of the fixed tooth 421, and the rotation of the first fixed bolt 41 and the second fixed bolt 411 continues, and the welding wire 5 on the side continues to weld at a uniform speed.

[0031] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
