The visual detection system is a known technology, and the visual detection system can be integrated into the main control system of the machining center as a subsystem.

[0022] As Figures 1 to 4 shown, the cutter recognition assembly 2 further comprises a cover 24, a linear module 25 and a connecting piece 26, the linear module 25 of the embodiment is a ball screw type linear module, and the linear module is a known technology. The cover 24 is a hollow tubular body with a closed top, the cover 24 is placed on the rear side of the tool magazine 11 and is fixed on the rack of the machining center body 1, the linear module 25 is vertically fixed in the upper part of the cover 24, the connecting piece 26 is a strip-shaped plate member, and the upper part of the connecting piece 26 is connected to the sliding block of the linear module 25. The first camera 21 and the second camera 22 are both fixed on the lower part of the connecting piece 26, and the first camera 21 is placed below the second camera 22. The linear module 25 can drive the connecting piece 26 to slide up and down, when the connecting piece 26 slides up, the first camera 21 and the second camera 22 can be moved into the cover 24, when the connecting piece 26 slides down, the first camera 21 and the second camera 22 can be moved out of the cover 24, and the first camera 21 and the second camera 22 can face the blade part of the cutter 900 on the tool magazine 11 reloading clamping position and the cutter code ring 27 on the cutter bar of the cutter 900 respectively. The third camera 23 is fixed on the rack of the machining center body 1 by a support.

[0023] The embodiment assumes that the magazine of the tool magazine 11 of the machining center body 1 has 20 positions, and the codes of the code disks 111 are A1, A2,..., A20 in sequence. The embodiment assumes that the machining plan uses 12 tools 900, and the codes of the 12 tool code rings 27 are B1, B2,..., B12 in sequence. The embodiment assumes that 6 tools 900 in the tool magazine 11 are used as main tools to complete six different machining processes of the whole product, and the other 6 tools 900 are also loaded into the tool magazine 11 as standby tools of the 6 main tools, that is, one main tool is matched with one standby tool, the functional parameters of the main tool are the same as those of the corresponding standby tool, but the code of the main tool is different from that of the standby tool.

[0024] Before loading the tools, the embodiment edits the basic information of the complete shape of the cutting edges of the 12 tools 900, the edge profile parameters, and the codes on the corresponding tool code rings 27 into the main control system of the machining center. The operator randomly loads the 12 tools 900 into any 12 positions of the tool magazine 11, and does not need to manually record the 12 position codes of the tool magazine 11 corresponding to the 12 tools 900. Then, the linear module 25 is instructed to move the connecting member 26 downward to move the first camera 21 and the second camera 22 out of the housing 24 to the working position and start the visual detection system. The position frame and the position code disk 111 of the tool magazine 11 are instructed to rotate intermittently, so that each tool 900 is rotated to the tool magazine 11 reloading position and stopped. At this time, the first camera 21, the second camera 22, and the third camera 23 can respectively collect the cutting edge state information of the tool 900 stopped at the reloading position, the code information of the tool code ring 27 on the tool 900, and the code information of the corresponding position code disk 111 of the tool 900 at the reloading position. When the position frame and the position code disk 111 of the tool magazine 11 rotate one revolution, the information of all the tools 900 in the tool magazine 11 and the corresponding code information on the position code disk 111 are collected. The collected information is fed back to the visual detection system for analysis and identification, so that each tool 900 can be automatically associated with the corresponding position code information. Since the functional parameters of the tools are distinguished by the codes on the tool code rings 27, the machining center can automatically select the required tools 900 for tool changing by using the selected tool program edited in advance and finding the associated position code according to the tool code before tool changing. After tool changing, the linear module 25 is instructed to move the connecting member 26 upward to move the first camera 21 and the second camera 22 into the housing 24.

[0025] If a tool 900 is damaged in use and is returned to the tool magazine 11 by the automatic tool changer, the tool edge damage state information will be collected by the first camera 21. After the visual detection system compares and identifies the abnormal state, the main control system can issue a warning and skip the damaged tool when the tool is needed again. The damaged tool can be replaced when the machine is stopped.

[0026] The three cameras of the tool recognition assembly 2 and the tool code ring 27 are arranged on the side of the machining center body 1 and the tool 900, respectively. The three cameras collect the tool edge state information of the tool 900 on the tool magazine 11, the code information of the tool code ring 27 on the tool 900, and the code information on the corresponding magazine code disc 111 of the tool 900 in the tool magazine 11. The visual detection system analyzes and identifies the information, so that the operator can automatically associate each tool 900 with the corresponding magazine information without recording the corresponding tool magazine 11 magazine code of different tools 900 when randomly loading the tool. The tool edge damage state of the tool 900 returned to the tool magazine by the automatic tool changer can be automatically identified, thereby improving the efficiency of the tool loading and changing of the machining center and avoiding the processing quality risk caused by the tool edge damage not being identified by the operator.

[0027] The above is only one specific embodiment of the present application, but the design concept of the present application is not limited to this. Any non-essential modification of the present application using this concept should be considered as an infringement of the protection scope of the present application.
