Abstract
Description
Technical Field
[0001] This invention relates to the field of rare earth metallurgical equipment technology, specifically to a fully automatic rare earth metal cutting device and its control method. Background Technology
[0002] In the production and processing of materials such as rare earth metals, sintered rare earth alloys, and rare earth permanent magnets, it is usually necessary to cut them to a fixed length according to the requirements of subsequent processes to obtain blanks or finished products with the required dimensions. Because rare earth metal materials are usually hard and brittle, easily oxidized, and have high chemical activity under local high temperature conditions, their cutting process has high requirements for feeding stability, positioning accuracy, clamping reliability, and safety protection of the cutting area.
[0003] Existing rare earth metal cutting equipment mostly employs manual feeding, manual positioning, or semi-automatic cutting methods. In these methods, the workpiece typically needs to be manually placed, adjusted, and positioned by the operator. The coordination between the cutting station and the loading, clamping, and unloading processes is insufficient, easily leading to unstable processing cycles. Furthermore, manual positioning is heavily influenced by operator experience, potentially causing deviations in the workpiece's feed depth, thus affecting the consistency of the cutting dimensions.
[0004] Furthermore, during the rare earth metal cutting process, frictional heat and localized extrusion heat are generated between the cutting tool and the workpiece. The fresh cut surface and debris, upon contact with air, may increase safety risks such as oxidation and combustion. Some existing cutting equipment lacks temperature detection for the cutting area, inert gas oxygen isolation, or a sealed protective structure, making it difficult to take effective protective measures in a timely manner based on temperature changes in the cutting area.
[0005] Meanwhile, existing equipment still relies on manual visual inspection for finished product testing after cutting, making it difficult to automatically identify cut defects, dimensional deviations, and batch completion status in a timely manner. Therefore, it is necessary to provide an integrated fully automatic rare earth metal cutting device and its control method that can achieve automatic feeding, precise positioning, stable clamping, safe cutting, argon gas protection to prevent oxidation and fire, and finished product testing. Summary of the Invention
[0006] The purpose of this invention is to provide a fully automatic rare earth metal cutting device and its control method, which aims to improve the lack of coordination in the feeding, positioning, clamping, cutting and detection processes in the existing rare earth metal cutting process, reduce the impact of manual positioning errors on the cutting size, and improve the safety and automation of the cutting process.
[0007] To achieve the above objectives, the present invention provides a fully automatic rare earth metal cutting device, comprising a main frame, a closed processing chamber, a pusher plate feeding mechanism, a positioning and clamping mechanism, a cutting module, a material collection platform, an electrical control cabinet, and a control console. The main frame is a basic support structure and is fixedly connected to the ground. The closed processing chamber is mounted above the main frame. The pusher plate feeding mechanism, the positioning and clamping mechanism, and the cutting module are respectively disposed within the closed processing chamber. The material collection platform is disposed at the end of the main frame and connected to the discharge port of the cutting module. The electrical control cabinet and the control console are disposed on the sides of the main frame and are electrically connected to the electrical components of the fully automatic rare earth metal cutting device.
[0008] The cutting module includes a fixed tool device, a cutting position, a tool, an infrared detection device, a fixed support, and an argon nozzle device. The fixed support is fixedly connected to the main frame. The fixed tool device, the cutting position, the tool, the infrared detection device, and the argon nozzle device are respectively mounted on the fixed support. The tool is fixedly connected to the fixed tool device and is arranged vertically opposite to the cutting position. The tool adopts a beveled blade structure, and its cutting edge is arranged at 30°~60° relative to the cutting direction of the workpiece. The cutting position is provided with a height difference and a beveled structure.
[0009] The enclosed processing chamber covers the cutting and processing area and the loading channel, and a safety light curtain is installed on the entrance and exit side of the chamber.
[0010] The pusher plate feeding mechanism includes a pusher plate, a directional guide rail, a pusher plate motor, and a vision camera. The directional guide rail is arranged along the workpiece feeding direction. The pusher plate is fixedly connected to the pusher plate motor. The pusher plate can move back and forth along the directional guide rail. The field of view of the vision camera is directly facing the moving area of the pusher plate.
[0011] The positioning and clamping mechanism includes a driving pulley, a transmission belt, a driven pulley, a guide slider, a vertical guide rail, a drive screw, and a pressing and fixing device. The driving pulley, transmission belt, and driven pulley form a transmission pair and are located on the side of the positioning and clamping mechanism. The drive screw is coaxially connected to the driven pulley. The vertical guide rail and the pressing and fixing device are arranged parallel to the drive screw. The guide slider is located on both sides of the vertical guide rail.
[0012] The material collection platform is equipped with a collection area, and a detection camera is installed above the collection area.
[0013] The electrical control cabinet is equipped with a central control system using a PLC controller, which is used to perform overall process control, signal acquisition, interlock judgment, alarm output and data recording. The corresponding outputs and operations are realized through the console.
[0014] This invention also proposes a control method for a fully automatic rare earth metal cutting device, which includes the following steps:
[0015] Step 1: Place the workpiece on the push plate and close the hatch;
[0016] Step 2: The vision camera detects the workpiece's position and orientation and determines its location;
[0017] Step 3: The push plate drives the workpiece forward, and the infrared detection device detects the feed rate;
[0018] Step 4: After the workpiece reaches the preset position, the positioning mechanism presses down and clamps it;
[0019] Step 5: The blade presses down to complete the cut, while the infrared temperature detection device monitors the temperature of the cut area in real time;
[0020] Step 6: When the temperature in the cut-off zone exceeds the threshold, the argon nozzle will automatically turn on;
[0021] Step 7: The cut workpiece is automatically unloaded, and the detection camera completes the finished product quality inspection, quantity statistics, and batch reminders.

The feeding mechanism is equipped with a vision camera for workpiece position and posture detection and feed correction. The positioning and clamping mechanism achieves adaptive workpiece clamping through belt and screw transmission. The cutting module uses a beveled blade for progressive cutting to reduce cutting heat. An infrared temperature measuring device in the cutting zone is linked to an argon gas nozzle, automatically adjusting the argon gas injection flow rate when a threshold is exceeded to isolate air and prevent oxidation and fire at the rare earth cut. The device relies on a multi-layered safety interlock system consisting of a chamber door, safety light curtain, workpiece arrival, and clamping signals; cutting can only be performed when all safety conditions are met. The material collection platform is equipped with a detection camera to automatically detect finished product appearance defects, count workpieces, and provide batch reminders. This invention achieves fully automated operation of rare earth billets from feeding, positioning, clamping, safe cutting, automatic unloading to finished product inspection, solving the shortcomings of existing equipment such as large errors from manual operation, easy oxidation and spontaneous combustion during cutting, reliance on manual quality inspection, and poor production safety, thus improving processing dimensional accuracy and production safety.

[0045] Please see Figures 1 to 5 The fully automatic rare earth metal cutting device will be further described below with reference to specific embodiments:
[0046] like Figure 1 As shown, the main frame 1 serves as the foundation support structure of the device, fixedly connected to the ground, and is used to bear the dynamic loads and vibrations of various functional modules such as feeding, positioning, cutting, protection, and collection. The enclosed processing chamber 2 is mounted above the main frame, covering the cutting processing area and the feeding channel, forming a relatively enclosed working space. This space is used to prevent debris from splashing, control the risk of personnel contact, and, in conjunction with argon gas protection, create a safe processing environment. Safety light curtains 6 are located on both sides of the enclosed processing chamber, forming an infrared protection zone for real-time detection of personnel entering the hazardous work area. When the safety light curtain detects unauthorized entry, the system immediately stops pushing, clamping, or cutting actions. The central control system is located in the electrical control cabinet 3, preferably using a PLC controller, and is electrically connected to the pusher motor, vision camera, infrared detection device, infrared temperature detection device, positioning mechanism, cutting drive unit, argon gas nozzle device, detection camera, and safety light curtains. It is used to perform overall process control, signal acquisition, interlock judgment, alarm output, and data recording. The unloading and collecting platform 5 is located at the end of the main frame and connects to the inclined discharge port of the cutting station. It is used to receive and collect the cut workpieces. The unloading and collecting platform has a collecting area 25, above which a detection camera 26 is installed to capture the appearance of the finished product, count the number of workpieces, identify the batch completion status, and send the detection results to the control console 4.
[0047] like Figure 2 The diagram shows a pusher plate feeding mechanism, installed at the front end of the main frame. This mechanism is used for the automatic feeding of rare earth metal workpieces and includes a pusher plate 7, a directional guide rail 8, a pusher plate motor 9, and a vision camera 10. The pusher plate 7 is the workpiece pushing execution component, contacting the end of the workpiece and sending it to the cutting station. The directional guide rail 8 is set along the workpiece feeding direction to constrain the linear motion trajectory of the pusher plate. The pusher plate motor 9 is preferably a servo motor, used to drive the pusher plate to reciprocate along the directional guide rail. The vision camera 10 is used to detect whether the workpiece has entered the pushing area and to collect real-time images of the workpiece's position and posture, feeding these images back to the central control system for loading position correction.
[0048] Figure 3The diagram illustrates the positioning and clamping mechanism, which is positioned between the push plate feeding mechanism and the cutting module. It is used for clamping and monitoring the workpiece after it enters the preset cutting position. The mechanism includes a drive pulley 11, a transmission belt 12, a driven pulley 13, a guide slider 14, a vertical guide rail 15, a drive screw 16, a pressing and fixing device 17, and an infrared temperature detection device 18. Specifically: the drive pulley 11, transmission belt 12, and driven pulley 13 form a transmission pair, providing rotational power for the clamping action; the drive screw 16 is coaxially connected to the driven pulley, converting the rotational motion into linear feed; the guide slider 14 and vertical guide rail 15 form a linear guide pair, constraining the vertical movement of the pressing and fixing device 17; the pressing and fixing device 17 clamps and fixes the workpiece; and the infrared temperature detection device 18 is positioned towards the cutting area to collect real-time temperature data of the cutting area during the cutting process.
[0049] Figure 4 This is a schematic diagram of the cutting module. The cutting module is located in the middle of the main frame, aligned with the pusher plate feeding mechanism and the positioning and clamping mechanism. It is used to achieve safe and efficient cutting of rare earth metal workpieces. It includes a fixed tool device 19, a cutting position 20, a tool 21, an infrared detection device 22, a fixed support 23, and an argon gas nozzle device 24. Specifically: the fixed support 23 is mounted on the main frame, providing rigid support for the cutting position; the fixed tool device 19 is used to install and drive the tool 21.
[0050] The cutting tool 21 preferably adopts a beveled blade structure, with its cutting edge arranged at 30° to 60° relative to the workpiece cutting direction, preferably 45°, to achieve a gradual cutting in. The infrared detection device 22 is set on the entrance side of the cutting station to detect the workpiece cutting depth. The argon gas nozzle device 24 is arranged directly opposite the cutting contact area and is linked with the infrared temperature detection device 18. The cutting position 20 is provided with a height difference and a beveled structure so that the cut workpiece can automatically slide into the unloading collection table.
[0051] Figure 5 This is a schematic diagram of the unloading and collecting platform 5. The unloading and collecting platform 5 is located at the end of the main frame and connects to the inclined discharge port of the cutting station. It is used to receive and collect the cut workpieces. The unloading and collecting platform has a collecting area 25, above which a detection camera 26 is installed to capture the appearance of the finished product, count the number of workpieces, identify the batch completion status, and send the detection results to the control console 4.
[0052] The central control system is located in electrical control cabinet 3, preferably using a PLC controller, and is electrically connected to the push plate motor, vision camera, infrared detection device, infrared temperature detection device, positioning mechanism, cut-off drive unit, argon nozzle device, detection camera and safety light curtain, and is used to perform overall process control, signal acquisition, interlock judgment, alarm output and data recording.
[0053] During the control and cutting of the workpiece, the device follows the following control logic:
[0054] (1) Correction of workpiece position deviation
[0055] The visual camera detects the actual center coordinates and attitude angles of the workpiece as Xc, Yc, and θc, respectively, and the preset target position and attitude angles are Xr, Yr, and θr, respectively. The workpiece deviation can then be expressed as:
[0056]
[0057] When the following formula is satisfied, the workpiece posture is determined to meet the loading requirements:
[0058]
[0059] Where εx, εy, and εθ represent the permissible errors for position and attitude, respectively.
[0060] (2) Judgment of cutting amount
[0061] Let the current displacement of the pusher be xp, and the reference starting position be x0, then the infeed amount L of the workpiece entering the cutting zone in It can be represented as:
[0062]
[0063] When the following conditions are met: When the workpiece reaches the preset cutting position, the clamping action is allowed to start. Here, Lset is the preset infeed threshold.
[0064] (3) Clamping stability relationship
[0065] To prevent the workpiece from shifting or slipping during the cutting process, the clamping force Fc applied by the pressing and fixing device preferably satisfies the following:
[0066]
[0067] in:
[0068] The disturbance force experienced by the workpiece during the cutting process; This represents the coefficient of friction of the clamping contact surface. When the clamping force satisfies the above relationship, the stability of the workpiece cutting process can be improved.
[0069] (4) Explanation of the formula for frictional heating in the cutting zone
[0070] The frictional heat generation power per unit time in the cut-off contact area can be approximately expressed as:
[0071]
[0072] in:
[0073] This refers to the power generated by frictional heating. The coefficient of friction; Normal contact force; This refers to the relative cutting speed.
[0074] Because the present invention uses a beveled blade for progressive entry, it can reduce the instantaneous contact area and make the normal load distribution more gradual, thereby reducing the peak contact stress and local heat accumulation, which helps to reduce the risk of oxidation and fire.
[0075] (5) Temperature-triggered argon gas protection status
[0076] Let the real-time temperature of the cut-off zone be... The preset temperature threshold is Then, if the following conditions are met: The central control system activates the argon nozzle device 24, injecting argon gas into the cut-off area. The argon gas injection flow rate can be adjusted according to the following relationship:
[0077] in: This refers to the argon gas injection flow rate; This is the temperature regulation coefficient. For real-time temperature monitoring, Tmax is a preset temperature threshold. The basic argon gas protection flow rate.
[0078] (6) Safety interlock logic
[0079] To ensure that the cut-off action is performed only under safe conditions, the cut-off permission signal can be represented as:
[0080]
[0081] in:
[0082] D is the door closing signal; G is the safety light curtain signal indicating no personnel have entered; P is the workpiece positioning signal; C is the clamping positioning signal. The tool is allowed to perform the downward cutting action only when S=1.
[0083] In conjunction with the control method of the present invention, the fully automatic rare earth metal cutting device described in this embodiment includes four stages: feeding and positioning, adaptive clamping, precise cutting and fire prevention control, and unloading collection and finished product inspection, as detailed below:
[0084] (1) Material feeding and positioning stage
[0085] The operator places the rare earth metal workpiece on the pusher plate 7 and closes the sealed processing door. The central control system first checks the door status and the safety light curtain status. After confirming that the safety conditions are met, the vision camera 10 acquires an image of the workpiece position, identifies whether the workpiece has entered the pushing zone, and judges the workpiece posture. Subsequently, the pusher plate motor 9 drives the pusher plate 7 to advance along the directional guide rail 8, conveying the workpiece to the vicinity of the cutting position 20. When the infrared detection device 22 detects that the workpiece infeed amount has reached the preset value, it outputs a workpiece arrival signal to the control system.
[0086] (2) Adaptive clamping stage
[0087] After the workpiece is in place, the driving pulley 11 drives the driven pulley 13 to rotate via the transmission belt 12, which in turn drives the screw 16 to rotate. The pressing and fixing device 17 moves downward in the vertical direction under the constraint of the guide slider 14 and the vertical guide rail 15, clamping and fixing the workpiece, thereby completing the adaptive positioning and clamping.
[0088] (3) Precise cut-off and fire prevention control stage
[0089] After clamping, the fixed tool device 19 drives the inclined blade 21 downward to cut the workpiece in a progressive cutting manner. During the cutting process, the infrared temperature detection device 18 monitors the temperature of the cutting area in real time; when the temperature exceeds the preset threshold, the central control system automatically activates the argon gas nozzle device 24 to spray argon gas into the cutting contact area, achieving local cooling and oxygen isolation protection. After cutting, the workpiece automatically slides to the material collection table 5 under the guidance of the inclined surface at the cutting position 20.
[0090] (4) Material collection and finished product inspection stage
[0091] After the workpieces slide into the unloading and collecting table 5 and gather in the collecting area 25, the detection camera 26 captures real-time images of the finished product's appearance and quantity. The system automatically identifies cutting defects, dimensional deviations, and quantity information using an image recognition algorithm. Once a batch of workpieces has been completely cut, the system sends an audible and visual alert to the control console 4, prompting the operator to remove the workpieces and proceed with further processing.
[0092] In summary, the present invention has the following beneficial effects:
[0093] Compared to existing rare earth metal cutting methods that rely on manual feeding, positioning, and unloading, this invention, through the coordinated operation of an automatic pusher feeding mechanism, an infrared detection device, a positioning and clamping mechanism, and a precision cutting module, enables rare earth metal workpieces to sequentially complete automatic feeding, infeed detection, clamping and positioning, and cutting actions, reducing positional errors caused by manual adjustments. Because the infrared detection device detects the workpiece infeed before cutting, the central control system only allows clamping and cutting actions to be executed when the actual infeed meets the preset range, thus improving the consistency of cutting dimensions.
[0094] Meanwhile, this invention employs a beveled blade for progressive cutting of rare earth metal workpieces. Compared to the flat-blade, full-contact cutting method, the beveled blade structure reduces the instantaneous contact area between the blade and the workpiece in the initial stage of cutting, minimizing localized frictional heat concentration and improving issues such as burrs, chipping, and localized temperature rise. An infrared temperature detection device and an argon gas nozzle are linked for control. When the temperature in the cutting area exceeds a preset threshold, the system automatically injects argon gas into the cutting contact area, thereby reducing the oxygen concentration in the cutting area and carrying away some heat. This mitigates the risk of oxidation and fire caused by fresh cut surfaces and debris being exposed to air during rare earth metal cutting.
[0095] Furthermore, the enclosed processing chamber, safety light curtain, and infrared tool entry detection device work together to form a safety interlock logic, ensuring that the cutting action is only performed after the chamber door is closed, personnel have left the danger zone, and the workpiece is in place, thereby improving the safety of the equipment during operation. After cutting, the workpiece can automatically enter the unloading collection table through the inclined discharge surface, and the detection camera identifies the cutting status and batch quantity, reducing the workload of manual visual inspection and counting, and facilitating the formation of an automated closed loop from loading, positioning, cutting, protection to quality inspection.
[0096] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
