The read-write distance can be determined by detecting the height between the reader 12 and the integrated circuit card 13 by means of a detection means such as a scale.

In summary, the detection base 1 is provided, and the first platform 2 and the linear motion follower 4 for placing the card reader 12 are provided on the detection base 1, and the second platform 3 is connected to the linear motion follower 4 and is used for placing the integrated circuit card 13, so that the second platform 3 can be driven by the linear motion follower 4 to ascend and descend, thereby adjusting the distance between the card reader 12 and the integrated circuit card 13, and facilitating the detection of the read-write distance of the integrated circuit card 13.

an output shaft of the stepping motor 403 is coaxially arranged with the ball screw 402, and a nut seat of the ball screw 402 is connected with the second platform 3.

The stepping motor 403 drives the second stage 3 to reciprocate along the screw of the ball screw 402.

In the embodiment of the present invention, the linear motion output device 4 includes a support 401, a ball screw 402 and a stepping motor 403.

In an alternative embodiment, the linear motion output device 4 further comprises a slide rail 404 fixed on the support 401 and a slide block 405 fixed on a nut seat.

The slide rail 404 is arranged parallel to the screw rod and is connected to the slide block 405 in a sliding manner, wherein the second platform 3 is fixed on the slide block 405.

In the embodiment of the present invention, the linear motion output device 4 may further include a slide rail 404 and a slide block 405 slidably connected to the slide rail 404. For example, the number of the sliding rails 404 may be two, and the two sliding rails 404 are respectively located at two ends of the screw and are arranged in parallel with the screw. Wherein the nut seat may be fixedly connected to the slider 405, and the second platform 3 is mounted on the slider 405. When the stepping motor 403 drives the second platform 3 to move up and down, the slider 405 can slide on the slide rail 404. Thereby, the structural stability of the linear motion follower 4 is improved.

In an alternative embodiment, the apparatus further comprises a step motor driver 5, wherein the step motor driver 5 is coupled to the step motor 403 to position the second platform 3 by controlling the rotation angle of the step motor 403.

In the embodiment of the present invention, the device may further include a step motor driver 5, for example, and the step motor driver 5 is an actuator for converting an electric pulse into an angular displacement. Which may be coupled to a stepper motor 403 to form a motor drive system. When the stepping motor driver 5 receives a pulse signal, the stepping motor 403 is driven to rotate by a fixed angle in a set direction. Therefore, the rotation angle of the stepping motor 403 can be controlled by controlling the number of pulses to be fed to the stepping motor driver 5, thereby achieving the purpose of accurately positioning the second stage 3 on the screw.

In one example, the card reader 12 is brought into contact with the second stage 3 to be in an initial state, and pulses are sent to the stepping motor driver 5 so that the second stage 3 vertically rises, and the number of pulses is counted. When the card reader 12 fails to read or write the integrated circuit card 13, the pulse transmission to the stepping motor driver 5 may be stopped, so that the stepping motor 403 stops moving. Therefore, the rising height can be calculated according to the relationship between the total number of pulses and the rotation angle, and the read-write distance to the integrated circuit card 13 can be determined, thereby improving the detection accuracy of the detection device.

In an alternative embodiment, the apparatus further comprises a controller 6, and the stepper motor driver 5 is coupled to the controller 6 and controls the rotation angle of the stepper motor 403 by receiving an electrical pulse from the controller 6.

The embodiment of the utility model provides an in, the device can also include controller 6, is coupled the pulse output of controller 6 with step motor driver 5's pulse input to controller 6 can be to step motor driver 5 input electric pulse, with the rotation angle that adjusts step motor 403 through the number of input electric pulse. Illustratively, the controller 6 may be model CL-01A and the stepper motor driver 5 may be model DM 542. When the controller 6 needs to work by using a dc power supply, a person skilled in the art can select a suitable ac-to-dc power supply module to supply power according to the working voltage of the controller 6.

Referring to fig. 1 and 2, in an alternative embodiment, a sensor group for detecting a position signal of the slider is disposed on the carriage 401, and the sensor group includes a first sensor 7 for detecting an upper limit position and a second sensor 8 for detecting a lower limit position.

The first sensor 7 and the second sensor 8 are each coupled to the controller 6 in order to transmit the slide position signal into the controller 6.

The embodiment of the present invention provides a sensor group for detecting a slider position signal can be disposed on the bracket 401, exemplarily, the first sensor 7 and the second sensor 8 can be disposed on the bracket 401 near to both ends of the screw rod, respectively, and the position of the first sensor 7 can be used for determining the upper limit position of the movement of the slider 405. The position of the second sensor may be used to determine a lower limit position of movement of the slider 405. Therefore, those skilled in the art can match the installation position of the sensor group on the bracket 401 according to the upper and lower limit positions in the actual detection process, and the invention is not limited herein. In one example, the slider 405 is generally made of a metal material, and the first sensor 7 and the second sensor 8 may be metal sensors.

In one example, the first sensor 7 and the second sensor 8 may be respectively coupled to the controller 6, so that when the slider 405 is detected to be at the upper limit position or the lower limit position, the controller 6 can receive the corresponding slider position signal, and can adjust the on/off of a switch such as a relay to control the stop of the stepping motor 403. Therefore, by detecting the upper limit position and the lower limit position of the slider 405, the device can be stopped in time after the slider 405 exceeds the movement range, thereby protecting the device from being damaged.

In an alternative embodiment, a zero sensor 9 for detecting a reader position signal is arranged on the slide 405, wherein the zero sensor 9 is coupled to the controller 6 for transmitting the reader position signal into the controller 6.

In the embodiment of the present invention, the zero point sensor 9 is coupled to the controller 6. Illustratively, the zero point sensor 9 may be an optical fiber sensor, and the zero point sensor 9 is used for detecting the position signal of the card reader and transmitting the signal to the controller 6. For example, the zero point sensor 9 may be mounted on the slider 405, and the zero point sensor 9 may just detect the card reader 12 when the slider 405 is at a certain position. Therefore, when the slider 405 descends to the position after the read-write distance is tested, and the zero point sensor 9 detects the card reader 12, the controller 6 can adjust the on-off of a switch such as a relay to control the stepping motor 403 to stop working.

Illustratively, the height of the integrated circuit card 13 from the reader 12 may be determined to be an initial distance when the slider 405 is in a certain position. Therefore, the rising height can be calculated by combining the relationship between the total number of pulses and the rotating angle, so that the corresponding actual reading and writing distance can be determined, and the detection precision of the device can be improved.

In an optional embodiment, a cavity 10 is disposed on the detection base 1, and the stepping motor 403, the stepping motor driver 5 and the controller 6 are disposed in the cavity 10.

The detection base 1 is provided with a heat dissipation hole 11 communicated with the cavity 10.

The embodiment of the utility model provides an in, in order to facilitate the installation of the part component in the device, improve the structural stability and the clean and tidy of device, can set up a cavity 10 on detecting base 1, supply the component to install. Illustratively, the stepper motor 403, the stepper motor driver 5, and the controller 6 may all be mounted within the chamber 10. Wherein, the output shaft of the stepping motor 403 penetrates the detection base 1 to provide a rotational force to the ball screw 402.

Because the stepping motor 403, the stepping motor driver 5 and the controller 6 all belong to electric elements, heat can be generated in the working process, the running performance of the device can be poor due to the fact that the heat cannot be dissipated, and elements are easily damaged. Therefore, the detection base 1 may be provided with a plurality of heat dissipation holes 11 communicating with the cavity 10.

In an alternative embodiment, the detection base 1, the first platform 2 and the second platform 3 are made of acrylic materials or wood.

In the embodiment of the present invention, it is considered that the ic card 13 may receive metal interference during the reading and writing process. In order to improve the detection precision of the device, for example, the detection base 1, the first platform 2 and the second platform 3 may be made of acrylic material or wood.

The working principle is as follows: the reader 12 is placed on the first platform 2 and the integrated circuit card 13 is placed on the second platform 3, and the distance between the integrated circuit card 13 and the reader 12 is determined as the initial distance. When the stepping motor driver 5 receives a pulse, the stepping motor 403 is controlled to drive the second platform 3 to vertically ascend, and meanwhile, the number of pulses is counted. When the card reader 12 fails to read or write the integrated card, the second platform 3 may be caused to stop rising. The actual rising height is calculated by combining the relationship between the number of pulses and the rotation angle of the stepping motor 403, and the actual rising distance is determined, so that the reading and writing distance is the sum of the initial distance and the actual rising distance. After the second stage 3 stops ascending, the stepping motor 403 drives the second stage 3 to descend, and when the optical fiber sensor detects the card reader 12, the second stage 3 may stop descending.

Therefore, the rotation angle of the stepping motor 403 can be controlled by controlling the number of pulses to be fed to the stepping motor driver 5, thereby achieving the purpose of accurately positioning the second stage 3 on the screw.

In summary, the detection base 1 is provided, and the first platform 2 and the linear motion follower 4 for placing the card reader 12 are provided on the detection base 1, and the second platform 3 is connected with the linear motion follower 4 and is used for placing the integrated circuit card 13. Therefore, the second platform 3 can be driven to lift by the linear motion follower 4, so as to adjust the distance between the card reader 12 and the integrated circuit card 13, and facilitate the detection of the reading and writing distance of the integrated circuit card 13. The manual stacking of the cushion blocks for measurement is avoided, and the detection efficiency is improved.
