[0002] Turning is a cutting and polishing device, which mainly uses a turning tool to turn the rotating workpiece. It can also use drills, reamer drills, reamers, taps, dies and knurling tools for corresponding cutting and polishing. It is the most widely used type of workpiece processing in machinery manufacturing and repair factories. According to the safety operating regulations: before turning starts, it is necessary to carefully check whether the various parts and protective devices of the machine tool are intact, safe and reliable in accordance with the requirements of safe operation. When the machine tool is running, it is strictly forbidden to wear gloves to operate, it is strictly forbidden to touch the rotating part of the machine tool with your hands, and it is strictly forbidden to transfer objects across the lathe during the operation of the lathe. However, in the actual production operation process, it is found that in order to prevent the burrs on the surface of the workpiece from hurting the hands, the staff chooses to wear gloves when carrying and chuck the workpiece. Due to the staff's weak safety awareness or taking the easy way out, they often turn on the device to cut and polish the workpiece without taking off their gloves.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] This embodiment introduces a safe and reliable cutting and polishing device. This device is mainly aimed at the actual production and processing process of workpieces. For example, when performing cutting and polishing operations on the intermediate rod of a plunger pump, in order to prevent the surface burrs of the intermediate rod of the plunger pump from hurting the hand, the staff chooses to wear gloves when handling and chucking the workpiece. However, when performing cutting and polishing operations, they forget to remove the gloves in time, which poses a great threat to the personal safety of the staff. The safe and reliable cutting and polishing device in this embodiment can automatically determine whether the staff wears gloves before performing cutting and polishing operations.

[0018] Such as Figure 1As shown in the figure, the device mainly includes: a cutting and polishing mechanism, an identity recognition system 1, an image acquisition unit 2, and a central processor. Specifically, The cutting and polishing mechanism is installed in the operation plant area and is used to perform the processing operation of cutting and polishing the workpiece. The identity recognition system 1 is set on one side of the cutting and polishing mechanism, establishes an information transmission connection with the central processor, recognizes the identity information of the staff, and obtains the startup permission of the cutting and polishing mechanism. The image acquisition unit 2 is installed on the upper part of the cutting and polishing mechanism and acquires the image information of the wearing characteristics and operation actions of the staff during the operation of the cutting and polishing mechanism.

[0019] The central processor includes an arithmetic unit and a controller. The central processor is set in the box body of the cutting and polishing mechanism and respectively establishes signal transmission and control connections with the cutting and polishing mechanism and the image acquisition unit 2. It receives the acquisition information from the identity recognition system 1 and the image acquisition unit 2, processes the acquired image information by using the image processing module in the arithmetic unit, finally forms an operation instruction, and transmits the operation instruction to the controller, and controls the startup and shutdown of the cutting and polishing mechanism through the controller.

[0020] In this embodiment, the purpose of setting the identity recognition system 1 is to clarify the identity information of the operators of the cutting and polishing mechanism, facilitate standardized management, and implement the main body of work responsibility.

[0021] The identity recognition system 1 adopts the recognition methods of face scanning recognition and smart card reading recognition of work permits, recognizes the identity information of the staff, and transmits the recognized identity information to the central processor.

[0022] When identifying the identity of the staff, the face scanning recognition uses a multi-camera to obtain the facial morphology information of the staff and recognize the identity information of the staff.

[0023] When reading and recognizing the smart card of the work permit, the smart card of the work permit and the card reader adopt non-contact recognition and reading (such as RFID / NFC), communicate with the card reader through radio waves, without physical contact, and only need to be close to the card reader to complete data exchange. The smart card of the work permit is internally provided with a storage chip to save the identity information of the staff (such as employee name, department, position, photo, permission level, etc.). The card reader is connected to the central processor to establish a database containing all staff information. The card reader reads the unique identifier (UID) of the smart card of the work permit and transmits it to the central processor through the interface. The central processor queries the database according to the received identifier, finds the corresponding staff record, and extracts the required identity information, and compares it with the identity information of the face scanning recognition. When the identity information comparison is consistent, it is determined as the same staff, and the startup operation permission of the cutting and polishing mechanism is obtained.

[0024] It should be noted that with reference to Figure 2, the cutting and polishing mechanism includes a headstock 3, a chuck 4, a tool rest 5, a carriage 6, a tailstock 7, a lead screw 8, a feed rod 9, and a bed 10.

[0025] The headstock 3 is arranged on one side of the bed 10. An image acquisition unit 2 is installed on the top of the headstock 3. A chuck 4 for fixing the workpiece is installed on the side of the headstock 3. An identity recognition system 1 is arranged on the other side of the headstock 3 adjacent to the chuck 4. The tool rest 5 for installing the turning tool is installed on the upper part of the carriage 6. The carriage 6 is slidably arranged on the lead screw 8 and the feed rod 9. One end of the lead screw 8 is power-transmission connected to the driving mechanism in the headstock 3, and the other end is rotatably installed on the bracket on one side of the bed 10. There are two feed rods 9, which are symmetrically arranged on both sides of the lead screw 8. The specific installation method is that one end of the feed rod 9 is fixedly installed on the headstock 3, and the other end is installed on the bracket on one side of the bed 10. A tailstock 7 is installed on the bed 10 at the end far from the headstock 3, and the tailstock 7 is located between the bracket of the bed 10 and the carriage 6. The driving mechanism in the headstock 3 is start-stop control connected to the controller of the central processor. Mainly by controlling the start and stop of the driving mechanism in the headstock 3, that is, controlling the rotation of the chuck 4, the rotation start and stop of the workpiece are controlled, and the cutting and polishing operation of the workpiece is stopped.

[0026] The image acquisition unit 2 uses a high-definition camera that can achieve 360-degree rotation shooting based on a pan-tilt head, shoots and acquires the image information of the wearing characteristics and operation actions of the staff, and transmits the image information to the central processor for arithmetic processing.

[0027] It is worth mentioning that in the arithmetic unit of the central processor in this embodiment, an image processing module is set up to preprocess the received image information, convert the color image into a grayscale image, use filters (such as Gaussian filtering, median filtering) to remove the noise in the image, and improve the edge detection accuracy. Then, the hand region image is segmented, the Canny edge detection algorithm is used to identify the edge of the region image, small noise points are removed, the larger contours are retained, the connected regions in the edge of the region image are marked, the part belonging to the hand is selected according to the area size, the geometric shape of the hand (such as the number of fingers, the width of the palm, etc.) is analyzed, a basic template is established for preliminary classification, the hand texture information including nails and joints is extracted, the local binary pattern is used to capture the texture change of the region image, a hand discrimination model is constructed based on the random forest learning algorithm, according to the difference between the texture of the glove and the hand skin, the two situations of wearing gloves and not wearing gloves on the hand are distinguished, a feedback mechanism is established, based on the operation image collected by the image acquisition unit 2, the hand discrimination model is used to judge whether the staff wears gloves. When it is detected that the staff wears gloves, the central processor triggers an alarm operation instruction to the controller, and the controller immediately shuts down the driving mechanism that provides power to the cutting and polishing mechanism.

[0028] In another application scenario of this embodiment, such asFigure 3 As shown, the application method of the automatic cutting and polishing device for workpieces is introduced. This application method includes the following steps: Identity recognition: Before the device is started, the staff holds the work permit smart card and swipes the card reader located on one side of the cutting and polishing mechanism. The identity recognition system 1 simultaneously performs a facial scan of the staff's facial morphological information to identify the staff's identity information. If it is consistent with the identity information of the work permit smart card read by the card reader, the start-up permission of the cutting and polishing mechanism is obtained.

[0029] Workpiece installation and image acquisition: The staff installs the workpiece on the chuck 4 of the cutting and polishing mechanism. Before the staff starts the cutting and polishing mechanism, the image acquisition unit 2 acquires the image information of the staff's wearing characteristics and operation actions, and transmits the image information to the central processor for arithmetic processing.

[0030] Safety recognition: The image processing module set in the arithmetic unit of the central processor preprocesses the image information, segments the hand area image, identifies the edge of the area image, marks the connected areas in the edge of the area image, selects the part belonging to the hand according to the area size, analyzes the geometric shape of the hand, extracts the hand texture information including nails and joints, uses the local binary pattern (LBP) to capture the texture change of the area image, calculates the LBP feature. For example, if the value of some bins in the LBP histogram exceeds the threshold (the threshold can be adjusted according to the actual situation), it is considered a glove; based on the random forest learning algorithm, the LBP feature vector is trained to construct a hand discrimination model, and according to the difference between the glove and the hand skin texture, the two situations of wearing gloves and not wearing gloves on the hand are distinguished.

[0031] Feedback mechanism: Based on the operation image collected by the image acquisition unit 2, the hand discrimination model is used to judge whether the staff wears gloves. When it is detected that the staff wears gloves, the feedback mechanism intervenes, and the central processor triggers an alarm operation instruction to the controller. The controller immediately shuts down the drive mechanism that provides power to the cutting and polishing mechanism, that is, terminates the operation action of the cutting and polishing mechanism; if it is detected that the staff does not wear gloves, the control feedback mechanism does not intervene, and the operator directly starts the cutting and polishing mechanism.

[0032] Factors such as the material, size, and tightness of the gloves may cause the gloves to be caught in parts such as the headstock, carriage, and chuck of the lathe, resulting in serious injuries to the arms, fingers, etc. The technical solution of the present invention can automatically determine the wearing characteristics of the operator and timely prevent the operation of wearing gloves when using the cutting and polishing device to perform cutting and polishing operations on workpieces. On the one hand, it standardizes the operation process of the operator, and on the other hand, it improves the safety awareness of the operator and ensures personal safety.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
