Can follow steel removal's seal molding robot
Technical Field
The invention relates to the field of steel plate processing equipment, in particular to a steel seal forming robot capable of moving along with steel.
Background
Most of the steel plates are required to be stamped with steel marks after being processed and molded, and relevant information of the steel plates is printed on the steel plates to be used as marks of the steel plates. In the process of stamping the steel seal, the steel seal forming device and the steel plate are required to be kept fixed, the steel plate is transmitted through the transmission line after being processed and formed, in order to reduce the frequency of steel plate transfer, the steel plate is subjected to steel seal forming in the transmission process of the steel plate on the transmission line, and the steel seal forming device is required to synchronously move for a certain distance along with the steel plate on the transmission line. At present, a multi-axis robot is mostly adopted to drive a steel seal forming device to move along with a steel plate to form a steel seal, and in order to enable the multi-axis robot to drive the steel seal forming device to move along with the steel plate, the moving speed of the steel plate is generally detected by collecting the transmission speed of a transmission line or by an image recognition mode; the steel seal forming device is absolutely fixed with the steel plate in a manner of sucking discs or electromagnets and the like when the steel plate is subjected to steel seal forming, so that the moving speed of the multi-axis robot driving steel seal forming device needs to be kept in accurate synchronism with the moving speed of the steel plate, and otherwise, the multi-axis robot is easy to damage. The steel plate is always in slipping with the transmission line in the transmission process of the transmission line, so that the actual moving speed of the steel plate is different from the transmission speed of the transmission line, and the actual transmission speed of the transmission line is always in error with the theoretical speed calculated by the driving motor of the transmission line, so that the synchronism is poor; the moving speed of the steel plate is detected by adopting an image recognition mode, so that the steel plate recognition error is easy to occur, the detection delay of the image processing on the steel plate speed is large, and the camera is polluted or damaged in a severe environment of a processing workshop.

In this embodiment, the multi-axis robot 1 drives the steel plate forming device 3 and the steel plate in the transmission process to move synchronously through the driving frame 2, so that the steel plate forming device 3 can be fixed on the steel plate to form a steel plate, and the tail end of the multi-axis robot 1 moves synchronously along with the steel plate forming device 3 in the steel plate forming process, wherein the fixing frame 21 of the driving frame 2 is fixedly connected with the mounting flange at the tail end of the multi-axis robot 1, the connecting frame 22 is fixedly connected with the steel plate forming device 3, the fixing frame 21 and the connecting frame 22 are movably connected through the movable chuck 23, the movable chuck 23 is in a reversed bell mouth shape and is movably clamped with the bayonet 24 on the connecting frame 22, so that the displacement generated between the steel plate forming device 3 and the tail end of the multi-axis robot 1 can be effectively buffered when the steel plate forming device 3 falls on the steel plate, and the impact on the multi-axis robot 1 is avoided when the steel plate forming device 3 contacts with the moving steel plate. In addition, the pressing push rod 4 provided on the fixing frame 21 is used for pressing and fixing the connecting frame 22 by continuously driving the end flange to move downwards through the driving of the multi-axis robot 1 after the steel seal forming device 3 is dropped on the steel plate and fixed. The synchronous detection device 5 arranged on the fixing frame 21 is used for contacting with a steel plate and detecting the relative displacement between the fixing frame 21 fixedly connected with the mounting flange at the tail end of the multi-axis robot 1 and the steel plate, when displacement exists between the fixing frame 21 and the steel plate, the detection roller 51 on the synchronous detection device 5 can rotate and is detected by the rotary encoder 52 and then transmitted to the controller of the multi-axis robot 1, and the detection roller is used as feedback quantity for controlling the horizontal moving speed of the tail end flange by the multi-axis robot 1, so that the speed of controlling the tail end flange by the multi-axis robot 1 is synchronous with the moving speed of the steel plate, and damage to the multi-axis robot 1 caused by the asynchronous moving speed is avoided.
The fixing frame 21 is in driving connection with the synchronous detection device 5 through the telescopic driving cylinder 6. The telescopic driving cylinder 6 can vertically and telescopically drive the synchronous detection device 5, when the multi-axis robot 1 prepares to place the embossed seal forming device 3 on a steel plate, the synchronous detection device 5 is firstly driven downwards through the telescopic driving cylinder 6 to be in contact with the steel plate, so that synchronous detection of the speed of the steel plate is realized, the tail end mounting flange is controlled to synchronously move at the speed of the steel plate, then the telescopic driving cylinder is continuously driven downwards to enable the embossed seal forming device 3 to fall on the steel plate, displacement caused between the embossed seal forming device 3 and the fixing frame 21 is reduced, the multi-axis robot 1 is driven downwards to fall on the steel plate, the telescopic driving cylinder 6 is continuously driven downwards to enable the pressing push rod 4 to be pressed on the connecting frame 22, and meanwhile, the synchronous detection device 5 is retracted upwards to be kept in contact with the steel plate, so that the relative displacement between the steel plate and the fixing frame 21 is continuously detected.
In addition, in order to avoid damage to the synchronous detection device 5 when the fixing frame 21 continues to move downward after the synchronous detection device 5 contacts with the steel plate, the driving rod of the telescopic driving cylinder 6 is connected with the synchronous detection device 5 through the elastic member 7, and a pressure sensor 71 is arranged at a position where the elastic member 7 abuts against the driving rod. The elastic component 7 can avoid the synchronous detection device 5 to suffer rigid collision, and simultaneously, the pressure sensor 71 can detect the pressure that the synchronous detection device 5 receives, so that when receiving great pressure, the multiaxis robot 1 can make timely adjustment to avoid the synchronous detection device 5 and the telescopic driving cylinder 6 to be damaged. The elastic component 7 may be a sliding cylinder with a buffer spring inside, the sliding cylinder is fixed at the tail end of a driving rod of the telescopic driving cylinder 6, and the synchronous detection device 5 is slidably arranged in the sliding cylinder and is in abutting connection with the buffer spring.
