The linkage between the various moving mechanisms of the equipment and the stamping structure is poor. The processing steps require manual intervention and cannot form a continuous automated processing flow. Summary of the Invention

The frame protection assembly includes a base and a protective cover, the interior of which forms a closed processing cavity for probe processing. The three-axis motion mechanism includes an XY-axis linear motor moving platform and a Z-axis servo module. The XY-axis linear motor moving platform drives the fixture assembly to perform two-dimensional displacement in a plane. The Z-axis servo module is vertically fixed above the base and outputs vertical stamping feed actions. The stamping execution component is located at the lower end of the Z-axis servo module and performs pressure-controllable closing stamping operations on the probe tip. The fixture assembly is mounted on the XY-axis linear motor moving platform and is used for probe positioning. The main control unit is located inside the base and is electrically connected to the human-machine interface component, the three-axis motion mechanism, and the stamping execution component.

[0006] Preferably, the human-machine interface component includes a touch screen and an operation button group; the touch screen is embedded in the outer side panel of the protective cover and is used for parameter input and equipment operation status display; the operation button group is assembled on the base and is used to issue equipment start / stop and emergency stop operation commands.

[0007] Preferably, the XY two-axis linear motor moving platform includes an X-axis sliding module and a Y-axis sliding module, with the Y-axis sliding module slidably stacked on top of the X-axis sliding module.

[0008] Preferably, the Z-axis servo module includes a servo electric cylinder, the output end of which is connected downward to the stamping execution component to drive the stamping execution component to complete the vertical stamping feed action.

[0009] Preferably, the stamping execution component includes a triaxial pressure sensing unit and a closing punch; the triaxial pressure sensing unit and the closing punch are coaxially arranged in the vertical direction, and the triaxial pressure sensing unit is located above the closing punch, and the triaxial pressure sensing unit is used to collect stamping load signals.

[0010] Preferably, the closing punch is made of tungsten steel and can be detachably mounted to the lower end of the triaxial pressure sensing unit.

[0011] Preferably, the fixture assembly includes a tray, which is fixed to the XY two-axis linear motor moving platform, and the tray surface has workpiece placement holes arranged in an array.

[0012] Preferably, the tray has a vacuum adsorption chamber inside, and the workpiece placement hole is connected to the vacuum adsorption chamber; the tray has a vacuum nozzle on its side, and the base has an air path control module, which is connected to the vacuum nozzle to regulate the air pressure in the vacuum adsorption chamber.

[0013] Preferably, the main control unit includes three servo drive modules. The three servo drive modules communicate with the main control unit through a CAN bus and independently drive the X-axis sliding module, the Y-axis sliding module and the Z-axis servo module, respectively, to drive the corresponding modules to complete the displacement action.

[0014] Preferably, the protective cover is provided with a transparent observation window.

[0015] The advantages of this invention compared to the prior art are: 1. This invention comprises a frame protection assembly, a human-machine interface component, a three-axis motion mechanism, a stamping execution component, a fixture assembly, and a main control unit. The operator issues stamping closing operation commands through the human-machine interface component, which are transmitted to the main control unit inside the base. The main control unit controls the operation of the three-axis motion mechanism and the stamping execution component according to the preset processing logic. The XY two-axis linear motor moving platform drives the fixture assembly to complete two-dimensional displacement to achieve workpiece alignment. The Z-axis servo module drives the stamping execution component to vertically feed and complete the probe closing stamping. After stamping is completed, the Z-axis servo module resets. The device sequentially switches workpieces for cyclic operation. All processes are completed within the closed processing cavity enclosed by the base and the protective cover. The operation signal is transmitted back in real time to form a closed-loop control, thereby realizing the automated continuous processing of the tubular probe stamping closing process.

[0016] 2. This invention features a touchscreen and a set of operation buttons. The touchscreen allows operators to input operating parameters such as the feed stroke of the three-axis motion mechanism and the stamping load of the stamping actuator according to the processing specifications of the tubular probe. During operation, the touchscreen can display real-time equipment status data, making it easy for operators to monitor the equipment's operating status. The operation button set can receive start / stop and emergency stop operations from the operator and generate control signals that are transmitted to the main control unit inside the base. After receiving the signals, the main control unit quickly adjusts the operating status of the three-axis motion mechanism and the stamping actuator to achieve equipment status switching and emergency braking. The two types of components work together to construct a complete human-machine control system, taking into account both equipment parameter debugging and operational safety management, thereby helping to improve the safety and control accuracy of the device.

[0017] 3. This invention is equipped with an X-axis sliding module and a Y-axis sliding module. The main control unit outputs displacement control signals based on preset machining coordinates, which drive the X-axis sliding module and the Y-axis sliding module to complete the lateral and longitudinal displacement adjustment respectively. The two modules can operate independently or in synchronous linkage without interfering with each other. This allows the fixture assembly to complete the position adjustment within the closed machining cavity of the frame protection assembly. Each preset stamping point corresponds to a stamping execution component, adapting to the needs of multi-station continuous stamping operations, thereby improving the positioning accuracy and operational adaptability of multi-workpiece continuous stamping processing.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 11As shown: A stamping and closing device for probe processing includes a frame protection assembly 1, a human-machine interface component 2, a three-axis motion mechanism 3, a stamping execution component 4, a fixture assembly 5, and a main control unit 6. The frame protection assembly 1 includes a base 11 and a protective cover 12, the interior of which forms a closed processing cavity for probe processing. The three-axis motion mechanism 3 includes an XY two-axis linear motor moving platform 31 and a Z-axis servo module 32. The XY two-axis linear motor moving platform 31 is used to drive the fixture assembly 5 to perform two-dimensional displacement in a plane, and the Z-axis servo... The module 32 is vertically fixed above the base 11 and is used to output vertical stamping feed action; the stamping execution component 4 is located at the lower end of the Z-axis servo module 32 and is used to perform pressure-controlled closing stamping operation on the probe tip; the fixture assembly 5 is installed on the XY two-axis linear motor moving platform 31 and is used for probe positioning; the main control unit 6 is located inside the base 11 and is electrically connected to the human-machine interface component 2, the three-axis motion mechanism 3 and the stamping execution component 4.

[0032] The operator issues a processing command for stamping and closing the tubular probe through the human-machine interface 2. The command is transmitted to the main control unit 6 inside the base 11. After receiving the command, the main control unit 6 outputs control signals to the three-axis motion mechanism 3 and the stamping execution component 4 according to the preset processing logic. During operation, the XY two-axis linear motor moving platform 31 in the three-axis motion mechanism 3 carries the fixture assembly 5 for two-dimensional planar displacement, adjusting the horizontal position of the fixture assembly 5 and transporting the fixture assembly 5 carrying the tubular probe to be processed to a position directly below the stamping station to complete the alignment of the workpiece. After alignment, the Z-axis servo module 32, vertically arranged inside the three-axis motion mechanism 3, receives the feed signal from the main control unit 6 and executes a vertical downward feed action, synchronously driving the stamping execution component 4, which is mounted at the lower end of the Z-axis servo module 32, to move downward as a whole. During the downward movement, the stamping execution component 4 smoothly contacts the tubular probe placed on the fixture assembly 5 and performs a standard closing stamping operation on the probe end. After a single tubular probe completes its end-forming stamping, the Z-axis servo module 32 drives the stamping execution component 4 to reset and lift upwards. The XY-axis linear motor moving platform 31 then adjusts the position of the fixture assembly 5, switches the workpiece to be processed, and performs the end-forming stamping operation again. The entire processing procedure is completed within the closed processing cavity formed by the base 11 and protective cover 12 of the frame protection assembly 1. The displacement parameters, stamping status, and temperature signals during device operation are transmitted back to the main control unit 6 in real time, forming a closed-loop control. Compared with traditional stamping devices that require manual alignment and segmented processing, this device achieves automated continuous processing of the tubular probe stamping end-forming process through the coordinated operation of various components and the unified scheduling of all processing actions by the main control unit 6. The process is closely connected, and no manual intervention is required throughout the entire process.

[0033] Reference Figure 2 and Figure 3 As shown: The human-machine interaction component 2 includes a touch screen 21 and an operation button group 22; the touch screen 21 is embedded in the outer side panel of the protective cover 12 and is used for parameter input and device operation status display; the operation button group 22 is assembled on the base 11 and is used to issue device start / stop and emergency stop operation commands.

[0034] The operator operates the touchscreen 21 to input core operating parameters such as the feed stroke of the three-axis motion mechanism 3 and the stamping load of the stamping actuator 4 according to the processing specifications of the tubular probe, thus completing the preset configuration of the processing parameters of the device. During the formal operation of the device, the touchscreen 21 continuously displays real-time operating data such as the displacement status of the three-axis motion mechanism 3 and the stamping condition of the stamping actuator 4, enabling the operator to monitor the overall operation of the device in real time and promptly identify whether the device is operating normally or abnormally. During the operation of the device, if it is necessary to start or stop the device normally, or if an emergency shutdown protection is required due to a sudden working condition, the operator can press the operation button group 22 mounted on the base 11. The operation button group 22 immediately generates the corresponding control command and stably transmits the control signal to the main control unit 6 inside the base 11. The main control unit 6 quickly responds to the received control signal and synchronously regulates the operation and stop status of the three-axis motion mechanism 3 and the stamping actuator 4, realizing rapid switching of the device's operating mode and emergency braking in case of failure. The touch screen 21 is responsible for parameter preset and operating condition monitoring, while the operation button group 22 is responsible for routine operation and emergency protection. The two types of components work together to form a complete human-machine operation system, which can meet the dual needs of precise device debugging and safety management, thereby effectively improving the safety and control accuracy of device operation.

[0035] Reference Figure 1 and Figure 4 As shown: The XY two-axis linear motor moving platform 31 includes an X-axis sliding module 311 and a Y-axis sliding module 312, with the Y-axis sliding module 312 slidably stacked on top of the X-axis sliding module 311.

[0036] Among them, the X-axis sliding module 311 and the Y-axis sliding module 312 are both linear motor driven structures.

[0037] During the processing, the main control unit 6 outputs corresponding displacement control signals to the XY-axis linear motor moving platform 31 based on the preset workpiece processing point coordinates. After receiving the signals, the X-axis sliding module 311 inside the XY-axis linear motor moving platform 31 starts first, completing displacement adjustment along the lateral direction of the device. The Y-axis sliding module 312, which is slidably stacked above the X-axis sliding module 311, can move independently along the longitudinal direction of the device synchronously or in stages, carrying the fixture assembly 5 mounted above it to follow the movement, completing the composite position adjustment of the lateral and longitudinal directions. In this structure, the X-axis sliding module 311 and the Y-axis sliding module 312 are independently controlled and their operation does not interfere with each other. This allows for single-axis individual alignment adjustment or coordinated dual-axis synchronous linkage displacement. With the cooperation of the X-axis sliding module 311 and the Y-axis sliding module 312, the fixture assembly 5 can complete the position adjustment inside the closed processing cavity enclosed by the frame protection assembly 1. Each preset stamping point corresponds to the stamping execution component 4, adapting to the needs of multi-station continuous stamping operations, thereby improving the positioning accuracy and operational adaptability of multi-workpiece continuous stamping processing.

[0038] Reference Figure 4 and Figure 5 As shown: The Z-axis servo module 32 includes a servo electric cylinder 321. The output end of the servo electric cylinder 321 is connected downward to the stamping execution component 4, and is used to drive the stamping execution component 4 to complete the vertical stamping feed action.

[0039] During the probe stamping and closing operation, the main control unit 6 outputs a vertical feed control signal to the servo cylinder 321 in the Z-axis servo module 32 according to the preset processing parameters. After receiving the signal, the servo cylinder 321 performs a stable linear extension and retraction motion along the vertical direction of the device, driving the stamping execution component 4, which is assembled at the lower end, to synchronously complete the lifting and lowering action. During the stamping operation, the servo cylinder 321 can adjust its downward speed and downward stroke in real time according to the segmented control signals output by the main control unit 6, so that the stamping execution component 4 smoothly and uniformly approaches the tubular probe to be processed, which is placed on the fixture assembly 5. When the stamping execution component 4 reaches the preset stamping working position, the servo cylinder 321 maintains a stable output state and cooperates with the device to complete the closing stamping operation of the probe end. After the stamping processing of a single workpiece is completed, the servo cylinder 321 automatically moves upward to reset, driving the stamping execution component 4 away from the workpiece processing position, waiting for the next round of processing instructions. The servo electric cylinder 321 can achieve adjustable control of feed speed and stamping stroke. The start and stop of vertical stamping action is controllable and the operation is stable. It can adapt to the stamping processing requirements of probes of different specifications.

[0040] Reference Figure 4 , Figure 5 and Figure 6As shown: The stamping execution component 4 includes a triaxial pressure sensing unit 41 and a closing punch 42; the triaxial pressure sensing unit 41 and the closing punch 42 are coaxially arranged in the vertical direction, and the triaxial pressure sensing unit 41 is located on the upper side of the closing punch 42. The triaxial pressure sensing unit 41 is used to collect stamping load signals.

[0041] The triaxial pressure sensing unit 41 is composed of three independent unidirectional pressure sensors: an X-axis pressure sensor, a Y-axis pressure sensor, and a Z-axis pressure sensor. The three sensors respectively collect the force loads in the transverse X, transverse Y, and vertical Z directions during the stamping process. The signal output terminals of the three sensors are electrically connected to the main control unit 6, which can synchronously collect the three-dimensional load data and transmit it to the main control unit 6.

[0042] The Z-axis servo module 32 drives the stamping execution assembly 4 to move downward as a whole. The triaxial pressure sensing unit 41 and the closing punch 42, which are arranged coaxially in the vertical direction, move downward synchronously. The closing punch 42 first contacts the tubular probe on the fixture assembly 5 and applies extrusion pressure. The load generated by stamping is transmitted to the triaxial pressure sensing unit 41 on the upper side of the closing punch 42 in real time. The triaxial pressure sensing unit 41 continuously collects the real-time stamping load signal and transmits the collected signal back to the main control unit 6 inside the base 11. The main control unit 6 adjusts the output thrust of the Z-axis servo module 32 in real time according to the feedback load signal to avoid the stamping pressure from exceeding the probe's bearing range, thereby avoiding the problem of workpiece breakage caused by excessive stamping pressure.

[0043] Reference Figure 6 As shown: The closing punch 42 is made of tungsten steel and can be detachably assembled to the lower end of the triaxial pressure sensing unit 41.

[0044] When different specifications of tubular probes need to be replaced with a suitable forming structure, the operator opens the protective cover 12, disassembles the tungsten carbide closing punch 42 assembled at the lower end of the triaxial pressure sensing unit 41, replaces it with a brand new tungsten carbide closing punch 42 suitable for the workpiece specifications, and then reassembles and fixes it. The tungsten carbide closing punch 42 has high hardness and is not prone to deformation or wear from long-term repeated stamping. The disassembly and assembly operation does not require disassembling the triaxial pressure sensing unit 41, Z-axis servo module and other components. Only the punch needs to be replaced to adapt to different processing requirements, thereby improving the service life of the closing punch 42 and adapting it to the processing of various specifications of probes.

[0045] Reference Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown: The fixture assembly 5 includes a tray 51, which is fixed to the XY two-axis linear motor moving platform 31. The tray 51 has workpiece placement holes 511 arranged in an array on its surface.

[0046] When the device performs the tubular probe stamping and closing operation, the main control unit 6 outputs a preset displacement command to the XY-axis linear motor moving platform 31, and the tray 51 completes two-dimensional planar displacement movement. Each workpiece placement hole 511 can independently place a single tubular probe to be processed, enabling the orderly placement and fixed support of multiple sets of workpieces at one time. During device operation, the tray 51, following the X-axis sliding module 311 and the Y-axis sliding module 312, synchronously completes the lateral and longitudinal position adjustment, transferring the batch of workpieces carried on the tray 51 to the stamping operation area inside the closed processing cavity. In batch processing mode, the XY-axis linear motor moving platform 31 finely adjusts the position of the tray 51 step by step according to the processing logic, sequentially aligning each arrayed workpiece placement hole 511 directly below the closing punch 42 of the stamping execution component 4, cooperating with the device to complete the closing stamping operation of each tubular probe. Compared to the traditional single-station, single-piece processing method, this 51-pallet array structure can realize batch clamping and continuous alignment conveying of workpieces, eliminating the need for operators to frequently load and unload materials. The device can continuously complete the stamping process of multiple sets of workpieces, thereby effectively improving the overall operation efficiency of probe stamping and finishing processing.

[0047] Reference Figure 8 and Figure 9 As shown: The tray 51 is provided with a vacuum adsorption chamber 512 inside, and the workpiece placement hole 511 is connected to the vacuum adsorption chamber 512; the tray 51 is provided with a vacuum nozzle 52 on the side, and the base 11 is provided with an air path control module 53, which is connected to the vacuum nozzle 52 to regulate the air pressure in the vacuum adsorption chamber 512.

[0048] Before the tubular probe stamping and closing operation begins, the tubular probes to be processed are placed one by one into the workpiece placement holes 511 of the tray 51. During device operation, the air path control module 53 installed inside the base 11 starts working. The air path control module 53 consists of a vacuum pump, a pressure regulating solenoid valve group, and a negative pressure regulating controller. The vacuum pump generates a negative pressure air source, the pressure regulating solenoid valve group controls the air path opening and closing, and the negative pressure regulating controller is electrically connected to the main control unit 6, receiving signals from the main control unit 6 to adjust the output negative pressure, thereby regulating and controlling the air pressure in the air path. The negative pressure airflow passes through the vacuum nozzle 52 provided on the side of the tray 51 and is introduced into the vacuum adsorption chamber 512 inside the tray 51, creating a stable negative pressure environment inside the vacuum adsorption chamber 512. Since the vacuum adsorption chamber 512 is interconnected with each workpiece placement hole 511, the negative pressure force can be evenly applied to the tubular probes inside the workpiece placement holes 511, firmly adsorbing and positioning the tubular probes at the preset processing position on the tray 51 surface. Throughout the entire process of the XY two-axis linear motor moving platform 31 shifting and positioning and the stamping execution component 4 stamping and closing, the air circuit control module 53 continuously maintains the negative pressure state inside the cavity, maintains the positioning stability of the tubular probe, effectively avoids workpiece offset and loosening caused by platform displacement and stamping impact vibration, thereby effectively improving the positioning accuracy and finished product qualification rate of batch probe stamping processing.

[0049] Reference Figure 2 and Figure 10 As shown: The main control unit 6 includes three servo drive modules 61. The three servo drive modules 61 communicate with the main control unit 6 via a CAN bus and independently drive the X-axis sliding module 311, the Y-axis sliding module 312 and the Z-axis servo module 32, respectively, to drive the corresponding modules to complete the displacement action.

[0050] The main control unit 6 contains three servo drive modules 61, each receiving independent control signals from the main control unit. The first servo drive module 61 transmits drive current to the X-axis sliding module 311 to control the X-axis lateral displacement. The second servo drive module 61 drives the Y-axis sliding module 312 to complete the longitudinal displacement. The third servo drive module 61 outputs power signals to the Z-axis servo module 32 to control the vertical stamping feed action. The three drive modules operate independently and can control a single moving part individually or output signals synchronously to achieve three-axis linkage displacement. The power supply of each module does not interfere with each other, and the motion parameters can be adjusted individually. The three-axis motion power is controlled separately, thereby realizing independent or linkage control of the three-axis motion mechanism 3.

[0051] Reference Figure 11 As shown: The protective cover 12 is provided with a transparent observation window 121. The transparent observation window 121 can be made of any one of acrylic, PC endurance board or tempered glass, and has the characteristics of light transmission and impact resistance.

[0052] The entire processing operation is carried out inside the processing cavity. The transparent observation window 121 of the protective cover 12 is connected to the internal space of the processing cavity. Operators can observe the workpiece movement of the internal pallet 51, the pressing and closing of the stamping actuator 4, and the movement of the three-axis motion mechanism 3 in real time through the transparent observation window 121 without opening the protective cover 12. The observation window 121 completely isolates the external environment from the processing cavity without damaging the closed protective structure. The operating status of the device can be observed in real time without stopping the machine or opening the door. The observation operation does not interrupt the processing flow, thus realizing convenient real-time observation of the device's operating status.

[0053] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
