A robot laser automated production equipment

Abstract

The present invention discloses a robot laser automated production equipment, which relates to the field of intelligent manufacturing technology, and includes a base, a first clamping assembly and a laser welding assembly. A box body is arranged on the outer side of the top of the base, and a first motor is arranged on the outside of the box body. A bidirectional lead screw is arranged at the output end of the first motor, and a first clamping assembly is arranged at the outer end of the bidirectional lead screw, and a first docking disk is arranged at the outer end of the first clamping assembly. The bidirectional lead screw of the present invention drives the displacement seat to separate, so that the disk bodies at both ends can pull the workpiece outward through suction force. If the workpiece is firmly welded at this time, the suction force will not be able to pull away the welded workpiece, so that the tension spring will be stretched. On the contrary, if the welding is not firm, the two workpieces will be pulled apart under the action of the tension, so that the staff can judge whether the workpiece is firmly welded by judging the change in the tension value of the tension spring.

Description

Technical Field

[0001] The invention relates to the technical field of robot laser production, and in particular to robot laser automated production equipment. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] During the use of common robot laser automated production equipment on the market, a large number of non-standard parts are welded, which leads to welding dead angles and welding interference points, which can easily cause cold welding or welding leakage, which has a great impact on the welding firmness.

[0016] The present invention provides a robot laser automated production equipment, which has the following beneficial effects:

[0017] 1. The present invention can make the active disk drive the driven disk to rotate through the transmission belt by the second motor. Because the driven disk is connected with the disk body, the disk body can drive the workpiece to rotate and adjust during the welding process. In addition, the first electric push rod can make the second docking disk fit the workpiece. At this time, the first docking disk releases the clamping of the workpiece, and the workpiece can be rotated to the clamping position of the second docking disk. At this time, the third motor drives the rotating disk to rotate, and the second docking disk drives the workpiece to rotate. Because the rotation of the rotating disk and the driven disk is vertically distributed, the steering angle of the workpiece can be further expanded, which can greatly avoid the generation of welding dead angles due to the shape of the workpiece during welding. In addition, During the welding process, the second electric push rod can move the lifting seat downward, which makes the height of the laser welding head flexibly adjustable, and the electric control screw rod can drive the laser welding head to move horizontally, and the fourth motor drives the rotating frame to rotate, so that the laser welding head can be rotated horizontally, and the electric control shaft can drive the laser welding head to rotate longitudinally. Through the above design, the laser welding head can be adjusted with high flexibility, and the workpiece transfer capability of the first docking plate and the second docking plate can be coordinated to greatly avoid position interference and dead angle of the workpiece during welding, which makes the equipment adaptable to the welding of various types of non-standard parts.

[0018] 2. A tension spring is provided at the connection between the disk surface and the disk body of the present invention, so that when the disk surface clamps the workpiece, if the clamping force is too large, the disk surface can rebound through the tension spring, which can effectively prevent the workpiece from being damaged or bent due to excessive clamping force when the disk surface clamps the workpiece. In addition, through the operation of the first suction pump, the suction force can be transmitted to the inside of the disk body through the rotating pipe, the connecting pipe, and the driven disk. The surface of the disk surface is provided with an adsorption groove, so that the suction force can be transmitted from the adsorption groove. At this time, the workpiece fits the disk surface, and is adsorbed with the aid of the adsorption force. The fixing stability between the disk and the workpiece can be improved. Since the workpiece cannot cover all the adsorption slots, the adsorption slots that are not adsorbed can act as vacuum cleaners. During the welding process of the workpiece, the welding slag can be sucked away by the adsorption slots close to the workpiece at the first time, which enables the equipment to automatically process the welding slag. Since the second docking disk has the same structure as the first docking disk and works through the second suction pump, the suction force can be transmitted to the inside of the second docking disk through the docking hose and the ventilation hose. This enables the second docking disk to also process the welding slag and assist in fixation when clamping the workpiece.

[0019] 3. The bottom end of the contact frame of the present invention is at the same height as the bottom end of the laser welding head, and because the coverage area of ​​the bottom end of the contact frame is large, when the workpiece rotates to touch the laser welding head, it will first contact the contact frame. After the contact frame contacts the rotating workpiece, it will be driven upward by the upward force of the workpiece during rotation, which enables the contact frame to squeeze the second reset spring inside the placement frame to move upward, and in the process of moving upward, the contact frame can drive the connecting frame to move upward synchronously, and the engaging tooth block at the outer end of the connecting frame can pass through the through groove and contact the oblique tooth groove on the inner side of the lifting cross frame. When the connecting frame moves upward, the engaging tooth block can drive the lifting cross frame to stretch the first reset spring and move upward inside the docking frame through the mutual engagement with the oblique tooth groove. Because the lifting cross frame is fixed to the second electric push rod, through this design, the contact frame can drive the laser welding head to rise and fall synchronously, thereby avoiding accidental contact between the workpiece and the laser welding head and causing damage to the laser welding head, thereby improving the safety of the equipment.

[0031] The specific operation is as follows: the staff places the workpiece to be laser welded on the inner side of the box body 2. At this time, the first motor 3 drives the bidirectional lead screw 4 to rotate, so that the displacement seats 501 at both ends can be displaced to the middle position of the box body 2. During the displacement process, the displacement seats 501 can make the disk bodies 601 at both ends close to each other, so that the disk surfaces 603 at both ends can fit and clamp the workpiece. After the workpiece is clamped stably, the second motor 502 works, which can make the active disk 503 drive the driven disk 505 to rotate through the transmission belt 504. Because the driven disk 505 is connected with the disk body 601, the disk body 601 can drive the workpiece to rotate and adjust during the welding process. In addition, the first electric push rod 705 works, which can make the second docking disk 706 fit the workpiece. At this time, the first docking disk 6 releases the clamping of the workpiece, and the workpiece can be transferred to the clamping position of the second docking disk 706. At this time, the rotating disk 704 is driven to rotate by the third motor 703, and the second docking disk 706 can drive the workpiece to rotate. Because the rotation of the rotating disk 704 and the driven disk 505 are vertically distributed, the steering angle of the workpiece can be further expanded, which can greatly avoid the generation of welding dead angles due to the shape of the workpiece during the welding process. In addition, during the welding process, the lifting seat 902 can be moved downward by the operation of the second electric push rod 901, which makes the height of the laser welding head 908 flexibly adjustable, and the operation of the electric control screw rod 905 can drive the laser welding head 908 to move horizontally and adjust the position, and The fourth motor 903 drives the rotating frame 904 to rotate, which can make the laser welding head 908 rotate horizontally and adjust the position, and the electric control shaft 907 can drive the laser welding head 908 to rotate vertically and adjust the position. Through the above design, the laser welding head 908 can be highly flexible in position adjustment. By cooperating with the workpiece transfer capabilities of the first docking plate 6 and the second docking plate 706, the position interference and position blind spots in the workpiece welding process can be greatly avoided, which makes the equipment adaptable to the welding of various types of non-standard parts. During the workpiece welding process, the first suction pump 508 works, and the suction force can be transmitted to the inside of the disk body 601 through the rotating tube 507, the connecting tube 506, and the driven disk 505. The surface of the disk 603 is provided with an adsorption groove 604, which makes the suction force The workpiece is then attached to the disk surface 603, and the fixing stability of the disk surface 603 and the workpiece can be improved through the auxiliary adsorption of the adsorption force. Since the workpiece cannot cover all of the adsorption grooves 604, the adsorption grooves 604 that are not adsorbed can act as vacuum cleaners. During the welding process of the workpiece, the welding slag can be sucked away by the adsorption grooves 604 close to the workpiece at the first time, which enables the equipment to automatically process the welding slag. Since the second docking plate 706 has the same structure as the first docking plate 6 and works through the second suction pump 707, the suction force can be transmitted to the inside of the second docking plate 706 through the docking hose 708 and the ventilation hose 709, which enables the second docking plate 706 to process the welding slag and assist in fixing when clamping the workpiece.The bottom end of the contact frame 1003 is at the same height as the bottom end of the laser welding head 908, and because the bottom end of the contact frame 1003 covers a larger area, when the workpiece rotates and touches the laser welding head 908, it will first contact the contact frame 1003. After the contact frame 1003 contacts the rotating workpiece, it will be driven upward by the upward force of the workpiece during rotation, which enables the contact frame 1003 to squeeze the second return spring 1002 inside the placement frame 1001 to move upward, and in the process of moving upward, the contact frame 1003 can drive the connecting frame 1004 to move upward synchronously, and the engaging tooth block at the outer end of the connecting frame 1004 1006 can pass through the through slot 805 and contact the oblique tooth groove 804 inside the lifting frame 803. When the connecting frame 1004 moves up, the engaging tooth block 1006 can drive the lifting frame 803 to stretch the first return spring 802 and move up inside the docking frame 801 by engaging with the oblique tooth groove 804. Because the lifting frame 803 is fixed to the second electric push rod 901, through this design, the contact frame 1003 can drive the laser welding head 908 to rise and fall synchronously, thereby avoiding accidental contact between the workpiece and the laser welding head 908 and causing damage to the laser welding head 908, which improves the safety of the equipment.

[0032] In summary, when this kind of robot laser automated production equipment is used, the staff first places the workpiece to be laser welded inside the box body 2, and at this time, the first motor 3 drives the bidirectional lead screw 4 to rotate, so that the displacement seats 501 at both ends can be displaced to the middle position of the box body 2, and the displacement seats 501 can make the disc bodies 601 at both ends approach each other during the displacement process, so that the disc surfaces 603 at both ends can fit with the workpiece and clamp it, because the connection between the disc surface 603 and the disc body 601 is provided with a tension spring 602, so that when the disc surface 603 clamps the workpiece, if the clamping force is too large, the disc surface 603 can rebound through the tension spring 602, which can effectively prevent the workpiece from being damaged or bent due to excessive clamping force when the disc surface 603 clamps the workpiece;

[0033] Then, after the workpiece is clamped and stabilized, the second motor 502 works, so that the active disk 503 can drive the driven disk 505 to rotate through the transmission belt 504. Because the driven disk 505 is connected with the disk body 601, the disk body 601 can drive the workpiece to rotate and adjust during the welding process. In addition, the first electric push rod 705 works, so that the second docking disk 706 can fit with the workpiece. At this time, the first docking disk 6 releases the clamping of the workpiece, and the workpiece can be transferred to the clamping position of the second docking disk 706. At this time, the third motor 703 drives the rotating disk 704 to rotate, so that the second docking disk 706 can drive the workpiece to rotate. Because the rotation of the rotating disk 704 and the driven disk 505 is vertically distributed, the steering angle of the workpiece can be further expanded, which can greatly avoid the generation of welding dead angles due to the shape of the workpiece during welding.

[0034] Then, during the welding process, the lifting seat 902 can be moved downward by the operation of the second electric push rod 901, so that the height of the laser welding head 908 can be flexibly adjusted, and the operation of the electric control screw rod 905 can drive the laser welding head 908 to perform lateral movement adjustment by the transverse seat 906, and the rotation of the rotating frame 904 driven by the fourth motor 903 can make the laser welding head 908 perform lateral rotation adjustment, and the electric control shaft 907 can drive the laser welding head 908 to perform longitudinal rotation adjustment. Through the above design, the laser welding head 908 can be highly flexible in position adjustment, and through the workpiece transfer capability of the first docking plate 6 and the second docking plate 706, the position interference and position dead angle during the workpiece welding process can be greatly avoided, which makes the equipment adapt to the welding of various types of non-standard parts;

[0035] In the subsequent welding process of the workpiece, the suction force can be transmitted to the inside of the disc body 601 through the operation of the first suction pump 508 through the rotating tube 507, the connecting tube 506, and the driven disc 505. The surface of the disc surface 603 is provided with an adsorption groove 604, which allows the suction force to be transmitted from the adsorption groove 604. At this time, the workpiece is fitted with the disc surface 603, and the auxiliary adsorption of the adsorption force can improve the fixing stability of the disc surface 603 and the workpiece. Because the workpiece cannot cover all the adsorption grooves 604, the adsorption grooves 604 that are not adsorbed can act as a vacuum cleaner. During the welding process of the workpiece, the welding slag can be sucked away by the adsorption grooves 604 close to the workpiece at the first time, which enables the equipment to automatically handle the welding slag. Because the second docking disc 706 has the same structure as the first docking disc 6, and the second suction pump 707 works, the suction force can be transmitted to the inside of the second docking disc 706 through the docking hose 708 and the ventilation hose 709, which enables the second docking disc 706 to handle the welding slag and assist in fixing when clamping the workpiece;

[0036] Because the bottom end of the contact frame 1003 is at the same height as the bottom end of the laser welding head 908, and because the bottom end of the contact frame 1003 covers a larger area, when the workpiece rotates and touches the laser welding head 908, it will first contact the contact frame 1003. After the contact frame 1003 contacts the rotating workpiece, it will be driven upward by the upward force of the workpiece during rotation. This allows the contact frame 1003 to squeeze the second return spring 1002 inside the placement frame 1001 to move upward, and in the process of moving upward, the contact frame 1003 can drive the connecting frame 1004 to move upward synchronously, and the engaging tooth block at the outer end of the connecting frame 1004 1006 can pass through the through slot 805 and contact the oblique tooth groove 804 on the inner side of the lifting cross frame 803. When the connecting frame 1004 moves upward, the engaging tooth block 1006 can drive the lifting cross frame 803 to stretch the first return spring 802 and move upward inside the docking frame 801 by engaging with the oblique tooth groove 804. Since the lifting cross frame 803 is fixed to the second electric push rod 901, through this design, the contact frame 1003 can drive the laser welding head 908 to be lifted and lowered synchronously, thereby avoiding accidental contact between the workpiece and the laser welding head 908 and causing damage to the laser welding head 908, which improves the safety of the equipment.

[0037] After the welding of the final workpiece is completed, the electromagnet 1007 adsorbs the engaging tooth block 1006, which can make the engaging tooth block 1006 squeeze the third reset spring 1005 and retract inside the connecting frame 1004, thereby releasing the lock between the engaging tooth block 1006 and the bevel tooth groove 804. At this time, the lifting cross frame 803 can return to its original position due to the reset of the first reset spring 802, thereby facilitating the passive giving way of the laser welding head 908 during the next round of welding.

[0038] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
