A plurality of robotic arm modules 3 are vertically arranged in the space of the profile frame 1 and are arranged above the base plate 2. A plurality of motors 4 cooperate with a plurality of robotic arm modules 3 to form a plurality of driving devices, which drive the pressure plates 5 to move vertically above the loading platform 6.

It is installed at the upper end of the base plate 2, or embedded and restricted between the base plate 2 and the profile frame 1.
[0044] The present invention's human vital sign signal simulation and generation device uses a motor 4 and a robotic arm module 3 to drive a pressure plate 5 to perform regular motions on a sensor 8, thereby simulating human vital sign signals. When the motor and robotic arm module drive the pressure plate 5 to perform regular, up-and-down motions against the sensor 8, it simulates a human breathing signal; when the pressure plate 5 vibrates the sensor 8 with regular, small amplitudes, it simulates a human heart rate signal; and when the pressure plate 5 vibrates the sensor 8 at a specific frequency, it simulates a human snoring signal.

The base frame is used to support and install the base plate 2, which is horizontally laid on the top of the base frame. The shape of the base frame is not limited, such as Figure 2 As shown, in one embodiment, four sections are used to form a rectangular base frame, and the rectangular base frame is fixed into shape by an L-shaped connector 11.

The linear screw module 31 further comprises a housing 3101, a slide 3102, and a limit sensor assembly 3103. A ball screw is mounted within the housing 3101. The motor 4 passes through the housing 3101 and drives the ball screw inside the housing to rotate. The ball screw converts the motor's rotational motion into linear motion, thereby driving the slide 3102 to slide up and down.
[0051] Furthermore, the slide plate 3102 is fixedly connected to the nut of the ball screw, and extends out of the housing 3101 to be fixedly connected to the adapter plate 32, so that the adapter plate is driven by the motor 4 to perform linear motion.

An adapter arm 33 is positioned perpendicular to the adapter plate 32 and fixed to the front end of the adapter plate 32, connecting to the pressure plate 5. The motor 4 drives the slide plate 3102 up and down via the ball screw.

[0055] Furthermore, the angle code limit bar hole 3201 is used for bolts to pass through and cooperate with the second angle code 13 to fix the second angle code 13 above and below the transfer arm 33, thereby supporting the upper and lower parts of the transfer arm 33 through the second angle code 13 to improve the stability of the transfer arm.
[0056] Furthermore, corresponding fixing slots are regularly provided on the upper and lower surfaces of the adapter arm 33 at the positions of the angle code limiting strip holes 3201 .
[0057] The arrangement of the angle code limit barcode 3201 and the transfer arm limit bar hole 3202 can facilitate the installation of the transfer arm and facilitate and quickly adjust the upper and lower positions of the transfer arm.
[0058] like Figure 1 As shown, the pressure plate 5 is fixed to the lower end of the transfer arm 33. The pressure plate 5 is positioned directly above the loading platform 6 via the transfer arm 33. To prevent or reduce damage to the sensor 8 on the loading platform 6 caused by the pressure plate 5, a buffer layer 51 is regularly provided on the lower surface of the pressure plate 5. The material and thickness of the buffer layer are not limited; preferably, a cushion made of an elastic material or a foamed elastic material is used.

To prevent and reduce the impact of vibrations during the movement of the motor 4 and the robotic arm module 3 on the sensor test results, a buffer pad 61 is regularly positioned between the stage 6 and the base plate 2. The material and thickness of the buffer pad 61 are not limited, and the same material as the buffer layer 51 can be used.
[0060] Furthermore, the controller 7 includes a housing, within which are located a PCB motherboard, an MCU, a power interface, a data interface, and a communication interface. The interfaces extend out of the housing for connecting to a power adapter and a data cable. The controller 7 is also provided with a display screen 71 for display and interaction. The display screen can be fixed to the controller or rotatably mounted on the upper end of the controller via a rotating assembly.
[0061] Furthermore, the controller 7 is also provided with a switch button and a control button for interaction.

[0063] The multi-station human body sign signal simulation generating device can be directly and quickly applied to industrialized automatic production, as shown in Figure 1 , a conveying belt is regularly arranged on the left and right directions in the middle area of the bottom plate 2, and the sensor 8 is transmitted through the conveying belt. Then a mechanical hand is regularly arranged on the front and rear sides of the bottom plate 2, and the sensor 8 is sucked or grabbed by the mechanical hand, and the sensor 8 is sucked or grabbed on the object table 6, so as to realize the automatic production test work, and the test efficiency of the sensor is greatly improved.
[0064] As shown in Figure 5 , Figure 6 and Figure 1 , it is the system principle diagram of the multi-station human body sign signal simulation generating device. The power module drives the operation of the breathing controller, the heart rate controller and the snoring controller in the controller 7. When the breathing frequency signal is sent to the motor by the breathing controller, the motor 4 drives the mechanical arm module 3 to drive the pressing plate 5 to do reciprocating motion, so as to simulate the human body breathing signal; when the heart rate frequency signal is sent to the motor 4, the motor 4 drives the mechanical arm module 3 to drive the pressing plate 5 to do small amplitude reciprocating motion, so as to simulate the human body heart rate signal; when the snoring frequency is sent to the motor 4, the motor 4 drives the mechanical arm module 3 to drive the pressing plate 5 to do vibration of a specific frequency, so as to simulate the human body snoring signal. Finally, the data collected by the sensor is displayed through the display screen of the controller.
[0065] Further, as shown in Figure 6 , when simulating the breathing and heart rate signs, the stepping motor and the mechanical arm module can be used for cooperation. When simulating the snoring sign, the eccentric motor and the mechanical arm module can be used for control and driving, and the mechanical arm module is driven by the eccentric motor to vibrate at a specific frequency, so as to simulate the human body snoring signal.
