DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0029] Reference Figure 2 and Figure 3 The present invention is an automatic framing device for plates at the end of a stamping line. The main structure includes a loading area 1 and a mobile vehicle 2 that can enter and exit the loading area 1. A framing manipulator 31 is provided in the loading area 1. For details, refer to Figure 1The loading area 1 is symmetrically arranged on the side of the conveyor belt 29. The plate 27 after the stamping process is completed is placed on the conveyor belt 29. A visual detector 30 is arranged above the end of the conveyor belt 29 to detect the stamping quality of the plate 27. The plate 27 that passes the inspection continues to move along the conveyor belt 29 to the area where the manipulator 31 is located. The manipulator 31 is provided with an end picker used in conjunction with the plate 27 to transfer the plate 27 from the conveyor belt 29 to the loading area 1 for framing operation. The mobile vehicle 2 is an AGV structure in the prior art, which can automatically locate to the loading area 1 and move the loaded plate 27 to the storage area. A plurality of running wheels 3 are arranged at the bottom of the mobile vehicle 2. The running wheels 3 are universal wheels, so that the mobile vehicle 2 The vehicle 2 can move in any direction, and uses its own battery as power to drive the walking wheels 3 to rotate, so that the mobile vehicle 2 can automatically move to the designated area. The loading area 1 is provided with a loading frame 4, and the loading frame 4 is used to load the stamped plates 27. The manipulator loads the stamped plates 27 on the stamping production line into the loading frame 4, which is convenient for transporting the plates 27 in batches. The bottom of the loading frame 4 is welded or bolted with a plurality of legs 5. The arrangement of the legs 5 leaves a gap between the bottom of the loading frame 4 and the ground. The height of the gap is greater than the height of the mobile vehicle 2, which is convenient for the mobile vehicle 2 to move into the bottom of the loading frame 4. The bottom of the legs 5 is rotatably connected to the rollers 6 through bearings. The rollers 6 are also universal wheels, so that the loading frame 4 can be moved to a designated area under the action of the roller 6. A receiving cavity 7 is welded or bolted on the top of the mobile vehicle 2. The receiving cavity 7 is a hollow cavity structure. An inlet and outlet 8 is provided on one side of the receiving cavity 7. An expansion frame 9 is connected to the receiving cavity 7 along a transverse sliding path. The expansion frame 9 moves to the outside of the receiving cavity 7 after passing through the inlet and outlet 8. Such a structure enables the expansion frame 9 to pass through the inlet and outlet 8 by transverse sliding, thereby allowing the expansion frame 9 to be stored in the receiving cavity 7 or extend out of the receiving cavity 7 to form a separate bearing structure. A side frame 10 is welded or bolted on one side of the expansion frame 9. A walking wheel 3 is also provided on the bottom of the side frame 10. After the expansion frame 9 extends out of the receiving cavity 7, the expansion frame 9 can be extended. The frame 9 can move with the mobile vehicle 2 under the action of the bottom rollers 6, thereby temporarily increasing the overall length of the mobile vehicle 2, so that it can simultaneously drive and move the two loading frames 4. The top of the accommodating cavity 7 and the top of the expansion frame 9 are both vertically slidably connected with a plurality of positioning columns 11, and the bottom of the loading frame 4 is provided with a plurality of positioning grooves 12 used in conjunction with the positioning columns 11. With such a structure, after the mobile vehicle 2 or the expansion frame 9 moves to the bottom of the loading frame 4, the plurality of positioning columns 11 move vertically upward into the positioning grooves 12 at the bottom of the loading frame 4. Thereafter, when the mobile vehicle 2 or the expansion frame 9 moves, the loading frame 4 can be driven to move under the cooperation of the positioning columns 11 and the positioning grooves 12, so that when the loading frame 4 filled with plates 27 is replaced,It is only necessary for the expansion frame 9 to slide horizontally to the outside of the accommodating cavity 7, so that one mobile vehicle 2 can move the empty loading frame 4 and the loading frame 4 filled with plates 27 at the same time with the cooperation of the expansion frame 9, so as to realize the rapid replacement and transfer of the loading frame 4, without the need for the cooperation of two AGVs, thus saving the number of AGVs, reducing the automated production cost of the stamping production line, improving the utilization rate of the mobile vehicle 2, and further improving the convenience of replacing the loading frame 4;

[0030] A steering wheel 13 and a power assembly for driving the steering wheel 13 to rotate are provided on one side of the loading area 1. The top of the steering wheel 13 is flush with the ground where the tail of the stamping line is located, so that the mobile vehicle 2 or the expansion rack 9 can move smoothly between the ground and the steering wheel 13. The power assembly is used to drive the steering wheel 13 to rotate around the center. The steering wheel 13 is provided with an identification area 14 at a position close to the loading area 1 and a position away from the loading area 1. An identification element, such as an infrared identification element or a pressure identification element, is provided in the identification area 14, so that it can generate an electrical signal when it identifies the mobile vehicle 2 or the expansion rack 9 entering the identification area 14. The area and position of the identification area 14 are adapted to the size of the mobile vehicle 2 or the expansion rack 9. The two identification areas 14 cooperate with the expansion rack 9 and the mobile vehicle 2, respectively. When the moving vehicle 2 is in use, that is, when the moving vehicle 2 enters the steering wheel 13 alone, it can only contact one identification area 14 at the same time. When the expansion frame 9 extends out of the moving vehicle 2 and moves into the steering wheel 13 with it at the same time, the two contact the identification areas 14 at two positions respectively, so that the identification areas 14 at the two positions generate electrical signals at the same time. When the moving vehicle 2 enters the steering wheel 13 alone, due to its size limitation, only one identification area 14 will generate an electrical signal. Both of the identification areas 14 are electrically connected to the power component. When the two identification areas 14 generate electrical signals at the same time, the power component electrically connected to them drives the steering wheel 13 to rotate. Such a structure enables the expansion frame 9 to slide out horizontally after the moving vehicle 2 carrying the empty loading frame 4 passes through the steering wheel 13 and enters the loading area 1. The mobile vehicle 2 enters under the loading frame 4 filled with plates 27, and the multiple positioning columns 11 on the expansion frame 9 move vertically into the positioning grooves 12 so that the expansion frame 9 and the loading frame 4 filled with plates 27 can move synchronously. At this time, the mobile vehicle 2 and the expansion frame 9 simultaneously drive the two loading frames 4 to leave the loading area 1 and enter the steering wheel 13, until the mobile vehicle 2 and the expansion frame 9 respectively enter the two identification areas 14 on the steering wheel 13, the electrical signals generated by the two identification areas 14 are simultaneously transmitted to the power component, and the power component drives the steering wheel 13 to rotate 180 degrees, so that the mobile vehicle 2 and the empty loading frame 4 face the loading area 1, and the expansion frame 9 and the loading frame 4 filled with plates 27 are located away from the loading area 1, and then the mobile vehicle 2 and the expansion frame 9 move toward the loading area 1. The empty loading frame 4 enters the loading area 1, and the positioning column 11 on the top of the mobile vehicle 2 descends and disengages from the positioning groove 12, leaving the empty loading frame 4 in the loading area 1 to realize the replacement of the loading frame 4. Thereafter, the positioning column 11 on the top of the expansion frame 9 descends and disengages from the positioning groove 12, and the expansion frame 9 slides horizontally to be stored in the accommodating chamber 7, and the mobile vehicle 2 moves into the bottom of the loading frame 4 filled with plates 27, and the positioning column 11 thereon rises and cooperates with the positioning groove 12 to drive the loading frame 4 filled with plates 27 to move. Such a structure can realize the transfer and replacement of the loading frame 4 with the cooperation of a mobile vehicle 2 with the expansion frame 9, thereby improving the utilization rate of the mobile vehicle 2, reducing the cost of automation transformation of the stamping production line, and preventing motion interference between multiple stamping lines.The complexity of route planning when replacing the loading frames 4 of multiple punching lines is reduced. There is no need to wait for the loading frames 4 full of plates 27 to be transferred before replacing the empty loading frames 4, so that the transfer and replacement are carried out simultaneously, which reduces the waiting time and the floor space occupied by the replacement area, greatly improves the efficiency and convenience of replacing the loading frames 4, and improves the efficiency and fluency of the automatic frame loading at the end of the punching line.

[0031] Preferably, refer to Figure 5 A plurality of pressure sensors are provided in the identification area 14, and the pressure sensors are electrically connected to the power assembly. Specifically, a floating plate is provided in the identification area 14, and the pressure sensors are distributed at various positions at the bottom of the floating plate, so that after the mobile vehicle 2 or the expansion frame 9 enters the floating plate on the identification area 14, the pressure sensors at one or more positions can generate pressure signals in time to ensure the accuracy of the identification of the mobile vehicle 2 or the expansion frame 9.

[0032] Preferably, the power assembly includes a steering motor 15 and a gear 16. There are two gears 16 that are respectively fixed to the side of the steering wheel 13 and the output shaft of the steering motor 15 by welding or bolts. The two gears 16 are meshingly connected. The pressure sensor is electrically connected to the steering motor 15. After the steering motor 15 receives the electrical signal from the pressure sensor, the steering motor 15 drives the steering wheel 13 to rotate under the meshing of the gears 16, thereby realizing the switching operation of the empty loading frame 4 and the loading frame 4 full of plates 27, making the switching operation smoother and more efficient.

[0033] Preferably, a plurality of partition plates 17 are fixed in the positioning groove 12 by welding or bolts, and the positioning column 11 is used in conjunction with the area between adjacent partition plates 17. Such a structure allows the area between adjacent partition plates 17 and the side walls of the positioning groove 12 to form a relatively closed space. After the positioning column 11 enters this space, its various positions are effectively restricted, so that the positioning column 11 and the positioning groove 12 are more closely matched, so that the mobile vehicle 2 or the expansion frame 9 can more accurately drive the loading frame 4 to move. The mobile vehicle 2 and the expansion frame 9 do not need to bear weight, but only need to push the loading frame 4 to move, thereby reducing the load-bearing pressure of the mobile vehicle 2 and improving the efficiency and convenience of driving the loading frame 4 to move.

[0034] Preferably, refer to Figure 4 A magnetic plate 18 is provided in the area between the adjacent partition plates 17 in the positioning groove 12. The magnetic plate 18 is made of an electromagnet or a permanent magnet. The magnetic plate 18 is magnetically attracted to the positioning column 11. After the positioning column 11 is extended into the positioning groove 12, it is magnetically attracted to the magnetic plate 18, so that the cooperation between the positioning column 11 and the positioning groove 12 is more secure. During the movement, the positioning column 11 is not easy to separate from the positioning groove 12, which further improves the stability of the moving drive of the loading frame 4.

[0035] Preferably, refer to Figure 8 The top of the accommodating cavity 7 and the top of the expansion frame 9 are both fixed with a lifting column 19 by welding or bolts. Specifically, an electric cylinder or a cylinder structure can be adopted. A bracket 20 is welded or bolted on the lifting column 19, and multiple positioning columns 11 are all located on the bracket 20. When the lifting column 19 is raised and lowered, such a structure can drive the bracket 20 and the multiple positioning columns 11 thereon to move up and down synchronously, so that the positioning columns 11 at multiple positions are matched with the multiple positioning grooves 12 at the same time, further improving the convenience and firmness of the plug-in matching of the positioning columns 11 and the positioning grooves 12.

[0036] Preferably, sliders 21 are symmetrically fixed on both sides of the expansion frame 9 by welding or integral molding, and a power rod 22 for driving the slider 21 to slide is provided in the accommodating cavity 7. The power rod 22 is used to drive the slider 21 and the expansion frame 9 to slide laterally in the accommodating cavity 7, so that the sliding structure of the expansion frame 9 relative to the moving vehicle 2 is more stable, less prone to up and down bumps or dislocation, and the firmness of the mobile drive of the loading frame 4 is improved.

[0037] Preferably, refer to Figure 6 and Figure 7 A telescopic motor 23 is fixed to the accommodating cavity 7 by welding or bolts, and the power rod 22 is fixed to the output shaft of the telescopic motor 23 by welding or a coupling. The telescopic motor 23 is used to drive the power rod 22 to rotate, and the power rod 22 passes through one of the sliders 21 and is threadedly connected thereto. When the power rod 22 rotates, the slider 21 and the expansion frame 9 slide in the accommodating cavity 7 under the action of the threaded connection, and the control of the sliding is more stable and accurate. A guide column 24 is fixed in the accommodating cavity 7 by welding or bolts, and the guide column 24 passes through another slider 21 and is slidably connected thereto. The setting of the guide column 24 provides guidance for the sliding movement of the slider 21 and the expansion frame 9, thereby avoiding misalignment or shaking of the expansion frame 9 relative to the accommodating cavity 7, and further improving the stability of the structure of the expansion frame 9.

[0038] Preferably, a retaining frame 25 for use with the loading frame 4 is provided in the loading area 1. Since the bottom of the loading frame 4 is provided with rollers 6 through the legs 5, the loading frame 4 is prone to move when the manipulator loads the plate 27 into the loading frame 4. The setting of the retaining frame 25 can fix the position of the loading frame 4 during loading to avoid the movement of the loading frame 4, thereby ensuring the firmness and accuracy of the loading operation. The retaining frame 25 is magnetically attracted to the side of the loading frame 4 near the bottom. Specifically, an electromagnet or a permanent magnet can be provided on the retaining frame 25, which will be magnetically attracted to the electromagnet or the permanent magnet when the loading frame 4 is close, thereby further improving the stability of the loading frame 4 during the loading operation.

[0039] Preferably, the loading frame 4 is provided with a loading port 26, that is, one side of the loading frame 4 is open, so that the robot can load the plate 27 into the loading frame 4 through the loading port 26. The loading frame 4 has a plurality of hanging rods 28 for hanging the plate 27 welded or bolted inside. For the plate 27 with a through hole in the middle, the through hole can be hung on the hanging rod 28, so that the plate 27 is more firmly placed in the loading frame 4.

[0040] Working principle: The structure of the present invention is provided with a accommodating chamber 7 on the top of the mobile vehicle 2, and an expansion frame 9 is connected to the accommodating chamber 7 along the horizontal sliding direction. A side frame 10 with a walking wheel 3 is provided on one side of the expansion frame 9. The expansion frame 9 passes through the inlet and outlet 8 on one side of the accommodating chamber 7 and moves to the outside of the accommodating chamber 7. The top of the expansion frame 9 and the top of the accommodating chamber 7 are both provided with a plurality of vertically sliding positioning columns 11, and the positioning columns 11 are used in conjunction with the positioning grooves 12 at the bottom of the loading frame 4. Such a structure enables the mobile vehicle 2 to move to the bottom of the empty loading frame 4, and the plurality of positioning columns 11 rise and cooperate with the positioning grooves 12, so that the mobile vehicle 2 can drive the empty loading frame 4 to move to the loading area 1. At this time, After the expansion rack 9 slides horizontally, it moves to the outside of the accommodating cavity 7, and the positioning column 11 on the top of the expansion rack 9 rises and cooperates with the positioning groove 12 at the bottom of the loading frame 4 filled with plates 27, so that the expansion rack 9 can transfer the loading frame 4 filled with plates 27 out of the loading area 1, and the mobile vehicle 2 places the empty loading frame 4 in the loading area 1. Only one AGV mobile vehicle 2 is needed to realize the synchronous transfer and replacement of the loading frame 4, which greatly improves the utilization rate of the AGV mobile vehicle 2, reduces the cost of replacing the loading frame 4, simplifies the operation steps of replacing the loading frame 4, and makes it less likely for motion interference to occur between multiple stamping lines, reducing the route of the loading frames 4 of multiple stamping lines when replacing The complexity of the planning further improves the convenience of replacing the loading frame 4; a steering wheel 13 and a power assembly for driving the steering wheel 13 to rotate are provided on one side of the loading area 1, and identification areas 14 are provided on the steering wheel 13 near the loading area 1 and far away from the loading area 1. The two identification areas 14 are used in conjunction with the expansion frame 9 and the mobile vehicle 2 respectively, and the two identification areas 14 are electrically connected to the power assembly. Such a structure enables the expansion frame 9 to extend out of the mobile vehicle 2 and transfer the loading frame 4 filled with the plate 27, and the mobile vehicle 2 and the expansion frame 9 move to the two identification areas 14 of the steering wheel 13 at the same time, so that the electrical signals generated by the two identification areas 14 at the same time are transmitted to the power assembly, and the power assembly The force assembly drives the steering wheel 13 to rotate 180 degrees, so that the loading frame 4 full of plates 27 and the empty loading frame 4 exchange positions, so that the empty loading frame 4 faces the loading area 1, and the steering wheel 13 will not rotate at other times, and will not interfere with the normal movement of the loading frame 4. Thereafter, the mobile vehicle 2 drives the empty loading frame 4 into the loading area 1 and puts it down, thereby realizing the rapid replacement of the loading frame 4. There is no need to wait for the loading frame 4 full of plates 27 to be transferred away before replacing it, which simplifies the replacement steps, makes the replacement operation of the loading frame 4 faster and smoother, and occupies a smaller area at the end of the stamping line, further improving the efficiency of replacing the loading frame 4.
