The needle penetration instrument of the invention also comprises a telescopic needle holder with scales for mounting standard needles with different specifications, and simultaneously ensures that the needle tips of the standard needles are level with the detection end of the sensor.
The automatic needle alignment penetrometer and the needle alignment method thereof according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a schematic structural view of an embodiment of the automatic needle penetration machine of the present invention, fig. 2 is a schematic structural view of an embodiment of the standard needle, and referring to fig. 1 and 2 in combination, the automatic needle penetration machine comprises a base 1, a lifting device 2 fixed on the base 1, a needle connecting rod 3 connected with the lifting device 2, a standard needle 4, a needle loader 5 and an inductor 6. The needle holder 51 is arranged at the bottom of the needle holder 5 and is used for fixing the preset position of the standard needle 4 at the bottom of the needle connecting rod 3, namely, the standard needle 4 with the preset specification for detection is installed, and meanwhile, the needle point height of the standard needle 4 is determined in the installation process, so that accurate needle alignment is facilitated. The sensor 6 is fixed at the bottom of the lifting device 2, and the detection end (bottom end) of the sensor 6 is flush with the needle tip of the standard needle 4, so as to detect whether the needle tip of the standard needle 4 reaches the surface of the sample 10 to be detected.
Further, in order to improve the automation degree of the needle process and the detection process, the needle penetration instrument of the invention further comprises a controller 7, wherein the lifting device 2 and the sensor 6 are electrically connected with the controller 7, and the controller is used for controlling the operation and the start and stop of the needle penetration instrument. Specifically, the controller 7 receives the detection result of the sensor 6 in real time, and controls the lifting device 2 to stop running according to the detection result, so as to complete automatic and accurate needle alignment.
In practice, standard needles 4 of different specifications are required for different samples 10. According to the invention, the needle loading devices 5 with corresponding fixed heights are respectively arranged for the standard needles 4 with different specifications, namely, the positions of the needle tips of the standard needles 4 with the specifications after being installed can be directly determined through the heights of the needle loading devices 5, so that the needle tips of the standard needles 4 are ensured to be level with the detection ends of the sensors 6. Under the condition, after the sensor 6 senses the surface signal of the sample 10 to be detected, the point of the standard needle 4 contacts the surface of the sample 10 to be detected, and then the sensor 6 sends a signal to the controller 7, and the controller 7 controls the lifting device 2 to stop running, so that the point of the standard needle 4 is effectively ensured to stay on the surface of the sample 10 to be detected, and the needle alignment is accurate.
In order to facilitate the determination of the distance between the tip of the standard needle 4 and the bottom of the body of the lifting device 2 after installation according to the height of the needle holder 5, in the device of the present invention, the needle holder 5 has an L-shaped structure comprising a vertical rod 52, and one side of the needle holder 51 is fixedly connected to the bottom end of the vertical rod 52.
Specifically, a positioning hole 510 is formed in the middle of the needle holder 51 for placing the standard needle 4 to be mounted, and the central axis of the positioning hole 510 is parallel to the upright 52. Meanwhile, no matter the positioning hole 510 is a counter bore or a through hole, the bottom end of the positioning hole 510 (namely, the needle point of the standard needle 4) is ensured to be flush with the bottom end of the upright 52 or the vertical distance in the height direction is ensured; for example, after standard needle 4 is placed in locating hole 510, its tip is 2mm or 5mm below the bottom end of upright 52; for another example, the depth of the locating hole 510 is less than the thickness of the needle holder 51 by a first predetermined distance, and the bottom end of the needle holder 51 is lower or higher (or may be flush) than the bottom end of the upright 51 by a second predetermined distance. Thus, when the standard needle 4 is installed, the top of the upright 52 is flush with the bottom of the main body of the lifting device 2, and the needle tip of the standard needle 4 can be directly (the bottom end of the positioning hole 510 is flush with the bottom end of the upright 52) or indirectly (the bottom end of the positioning hole 510 is not flush with the bottom end of the upright 52, but the vertical distance between the two is determined) determined to be flush with the detection end (bottom end) of the sensor 6 only by the height of the upright 52.
It should be noted that the bottom end of the positioning hole 510 has a tapered structure, which is adapted to the shape of the tip end of the standard needle 4, so as to ensure that the standard needle 4 is installed upright, and the accurate tip is flush with the detection end (i.e., bottom end) of the sensor 6.
In another exemplary embodiment, the upright 52 of the needle holder 5 can also be designed as a telescopic structure, and graduations are provided on the upright 52. In the installation and use, aiming at standard needles with different specifications, only the upright rod 52 of the needle loader 5 is required to stretch to the corresponding scale position; then, the standard needle 4 is held to a height capable of being fixedly installed and fixed with the bottom end of the needle connecting rod 3 only by the needle holder 51, and the tip of the standard needle 4 is flush with the detection end of the sensor 6.
It should be noted that in the penetrometer of the present invention, the sensor 6 is selected as a proximity sensor. When the detection end of the proximity sensor contacts the surface of the sample 10 to be detected, a confirmation signal is sent to the controller 7, the controller 7 controls the lifting device 2 to stop running, and the needle tip of the standard needle 4 which is flush with the detection end of the proximity sensor stays on the surface of the sample 10 to be detected, so that accurate needle alignment is completed.
In the invention, a top suction type connecting structure is arranged between the top end of the needle connecting rod 3 and the bottom end of the lifting device 2. In the existing automatic needle penetration instrument, the connection mode of the needle connecting rod is mainly that an electromagnet is adopted to clamp from the side face, so that the needle connecting rod can vibrate to some extent in the clamping process, and the equipment precision is affected. In the invention, the electromagnet is arranged at the top of the device, so that the accuracy of the needle connecting rod in the installation and use processes is effectively ensured.
In addition, the penetrometer of the invention further comprises a water tank 8 positioned on the base 1, wherein a temperature sensor 81 is arranged in the water tank 8, and the temperature sensor 81 is in signal connection with the controller 7. The temperature sensor 81 is used for detecting the temperature in the water tank 8 and sending the detection result to the controller 7 so as to detect and ensure the temperature of the environment (water tank) where the sample 10 to be tested is located during the test, and meanwhile, the measurement and the detection result are beneficial to the subsequent statistics and research.
Specifically, the controller 7 is provided with a signal receiving module for receiving the signal or the detection result of the sensor 6 and/or the temperature sensor 81, and a signal transmitting module for transmitting a stop signal to the lifting device 2. In addition, for convenience of study and statistics, a storage module may be further provided in the controller 7 for storing the detection result of the temperature sensor 81 and the final penetration detection result of the sample corresponding to the detection result in real time.
The invention also provides a needle alignment method of the needle alignment instrument, wherein the needle alignment method is shown in a flow chart of FIG. 3, and the needle alignment method comprises the following steps with reference to FIG. 3:
The standard needle 4 with the preset specification is arranged at the bottom end of the needle connecting rod 3 through the needle arranging device 5, so that the needle point of the standard needle 4 is ensured to be level with the detection end of the sensor 6;
Starting the lifting device 2 and the sensor 6, detecting signals of the to-be-detected sample 10 by the sensor 6 in real time, and sending detection results to the controller 7;
after receiving the signal sent by the sensor 6, the controller 7 controls the lifting device 2 to stop running, and the needle alignment is completed.
In the needle alignment method of the needle penetrometer of the present invention, ensuring that the tip of the standard needle 4 is flush with the detection end of the sensor 6 is an important precondition for accurate needle alignment, and therefore, accurate installation of the standard needle 4 is extremely important.
Specifically, loading the standard needle 4 of a predetermined specification into the bottom end of the needle link 3 by the needle loader 5 includes the steps of:
Selecting a needle loader 5 matched with a standard needle 4 with a preset specification;
placing the needle tip of the standard needle 4 of a predetermined specification into the positioning hole 510 of the needle loader 5;
The top end of a standard needle 4 with a preset specification is placed into a mounting hole at the bottom end of a needle connecting rod 3 by moving a needle loading device 5;
