Description

Technical Field

[0001] The present invention relates to the technical field of single-chip computer detection equipment, in particular to a single-chip computer detection device with automatic plugging and unplugging. Background Art

[0002] Before a single-chip microcomputer leaves the factory, it needs to be tested to determine whether the correct program has been written into it. The traditional testing method is to manually pick up the single-chip microcomputer from the conveyor line next to the single-chip microcomputer, and then plug and unplug the single-chip microcomputer on the testing circuit board. The testing circuit board is used to test the single-chip microcomputer during the plug-in and pull-out intervals. This testing method is labor-intensive and prone to problems such as pin bending due to pin misalignment with the insertion hole, and even pin damage or pin scratches. In addition, in order to ensure the conductivity between the pin and the testing circuit board, the friction between the pin and the testing circuit board is constant and large during the pin plug-in and pull-out process. As a result, during the process of multiple pin plugging and unplugging, the friction loss at the connection between the testing circuit board and the pin is large, reducing the service life of the testing circuit board and the long-term testing effect.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 A single-chip microcomputer detection device with automatic plug-in and pull-out includes a carrier 1, an experimental board pad 2 and a workbench 12 arranged in parallel, and the carrier 1 is arranged between the experimental board pad 2 and the workbench 12.

[0023] The workbench 12 is fixedly connected to a column 21 at one end facing the carrier 1, and a mounting platform 22 is sleeved on the outer surface of the column 21. The mounting platform 22 is fixedly mounted on the column 21 by bolts, and the experimental board pad 2 is fixedly mounted on the mounting platform 22 at one end facing the carrier 1, and the experimental board pad 2 is connected to a wire and is connected to the main control circuit board through the wire.

[0024] It should be noted that the mounting platform 22 has a first mounting position and a second mounting position on the column 21. The distance from the first mounting position to the workbench 12 is greater than the distance from the second mounting position to the workbench 12, and when the experimental board pad 2 is needed for detecting the microcontroller, the mounting platform 22 is installed at the second mounting position.

[0025] The main control circuit board is connected to a display, which displays the microcontroller's test results. Specifically, when the microcontroller is correctly programmed, the speaker in the display emits a beeping sound and the screen displays a regular indicator wave. When the microcontroller is incorrectly programmed, the display does not emit a beeping sound and displays an incorrect result.

[0026] A slot 101 for accommodating a microcontroller is provided on one end of the carrier 1, facing the pad 2 of the experimental board. The microcontroller slides in and out of the slot 101. It should be noted that when sliding multiple microcontrollers into the slot 101 in succession, the multiple microcontrollers should slide into the slot 101 in the same direction, with all pins of the microcontrollers vertically facing the pad 2 of the experimental board.

[0027] A plurality of tube legs 3 are inserted and fixedly connected on the experimental board pad 2, and the plurality of tube legs 3 correspond one-to-one to the plurality of pins of the single chip computer in the card slot 101, and the tube legs 3 are used to accommodate the pins; both ends of the tube legs 3 are exposed from the experimental board pad 2, and a trumpet tube 4 is formed on the end of the tube leg 3 facing the carrier 1 for the pins to enter and exit, and the opening with a larger diameter on the trumpet tube 4 is used as the entrance and exit for the pins to enter and exit the trumpet tube 4, and the opening with a smaller diameter on the trumpet tube 4 is used as the entrance and exit for the pins to enter and exit the tube legs 3, so that in the process of the pin entering the tube legs 3 from the trumpet tube 4, the diameter of the space around the pin is gradually reduced, which can facilitate the pin to enter the tube legs 3 while effectively ensuring the straightness of the pin.

[0028] A through slot 301 is formed on both sides of the tube leg 3 located between the experimental board pad 2 and the speaker tube 4. The through slot 301 is arranged along the axial direction of the tube leg 3. A spring 5 is formed on the groove wall surface of each through slot 301 near the speaker tube 4. The spring 5 is "V" shaped, and the V-shaped angle points outward from the tube leg 3. The two springs 5 ​​located on the same tube leg 3 are used to press against the two sides in the thickness direction of the pin, and the side of the spring 5 used to press against the pin is set as a plane. The maximum distance between the two planes used to press against the same pin is greater than the thickness of the pin. During the process of inserting the pin into the tube leg 3, at least one of the two planes is spaced from the pin, allowing the pin to move between the two planes or move in a manner that fits a plane with low friction loss, reducing the friction loss of the spring 5 during multiple insertions and removals, thereby ensuring good conductivity during multiple tests.

[0029] A pressure plate 6 is sleeved on the outer circumference of the tube leg 3 located between the spring piece 5 and the speaker tube 4; two pressure plates 6 are provided, and multiple tube legs 3 located on the same side pass through the same pressure plate 6; a spring 7 is provided between each pressure plate 6 and the experimental board pad 2; the pressure plate 6 can move back and forth relative to the experimental board pad 2, and when the pressure plate 6 moves toward the side close to the experimental board pad 2 under the action of external force, the pressure plate 6 compresses the spring 7 and can press the spring 5 toward the pin, so that the spring 5 is in close contact with the pin; when the external force that makes the pressure plate 6 close to the experimental board pad 2 disappears, the spring 7 resets, pushing the pressure plate 6 to move toward the side of the speaker tube 4, and the spring 5 rebounds and detaches from the pin.

[0030] A push rod 8 is installed at the other end of the carrier 1, and the push rod 8 can move back and forth along the line connecting the carrier 1 and the experimental board pad 2; the end of the pressure plate 6 away from the experimental board pad 2 can cooperate with the carrier 1.

[0031] After being positioned in the single-chip computer slot 101, the push rod 8 is moved toward the side close to the experimental board pad 2, pushing the carrier 1 close to the experimental board pad 2, and inserting multiple pins into multiple speaker tubes 4 respectively. Then, the carrier 1 continues to approach the experimental board pad 2 and contacts the pressure plate 6, pushing the pressure plate 6 toward the experimental board pad 2, compressing the spring, so that the pin extends into the tube leg 3, and the spring 5 presses against the pin. During this process, the friction between the spring 5 and the pin increases from small to large, and the minimum value of the friction can be zero. The maximum friction occurs when the pin enters the tube leg 3 and is in place. After the friction is at its maximum, there is no relative displacement between the spring 5 and the pin, which greatly reduces the friction loss of the spring 5.

[0032] After completing the single-chip microcomputer test, the push rod 8 is moved away from the pad 2 of the experiment board, driving the carrier 1 away from the pad 2 of the experiment board. The spring 1 7 pushes the pressure plate 6 away from the pad 2 of the experiment board, and the spring 5 rebounds, reducing the friction between the spring 5 and the pin, and the pin moves toward the outside of the tube leg 3 until it moves outside the tube leg 3. During this process, the friction between the spring 5 and the pin decreases, and the maximum friction state lasts for a short time, resulting in less friction loss caused by the maximum friction state, further reducing the friction loss of the spring 5.

[0033] The line connecting the carrier 1 and the pad 2 of the experimental board is perpendicular to the opposite surfaces of the carrier 1 and the pad 2 of the experimental board.

[0034] As a further explanation of the above technical solution, the present invention also includes a turntable 9 parallel to the experimental board pad 2, and a rotating shaft 91 is fixedly connected to the center position of the end of the turntable 9 away from the experimental board pad 2. The end of the rotating shaft 91 away from the turntable 9 passes through and is rotatably connected to the workbench 12, and the end of the push rod 8 away from the carrier 1 passes through and is slidably connected to the workbench 12.

[0035] A motor 13 is fixedly installed at one end of the workbench 12 away from the turntable 9, and the output end of the motor 13 and the rotating shaft 91 are connected together by a pair of bevel gears, and the bevel gear installed on the motor 13 is an incomplete gear, so that the two bevel gears are connected through a gap transmission, so that the bevel gear installed on the motor 13 has a transmission state and an idling state, and the transmission state and the idling state appear alternately; when the bevel gear installed on the motor 13 is in the transmission state, the turntable 9 is driven by the motor 13 and rotates around the rotating shaft 91, and when the bevel gear installed on the motor 13 is in the idling state, the turntable 9 is stationary; it should be noted that, in order to ensure that the turntable 9 has a stationary state and a rotating state, a spring column is provided between the turntable 9 and the workbench 12, and the movable end of the spring column can be pluggably inserted into a plurality of jacks on the rotating shaft 91 in sequence.

[0036] A drive wheel 14 is coaxially fixedly mounted on the output end of motor 13. Drive wheel 14 is provided with a cam-shaped drive slot, into which push rod 8 extends. When the bevel gear mounted on motor 13 is in the transmission state, drive wheel 14 rotates, and push rod 8 remains stationary relative to workbench 12. When the bevel gear mounted on motor 13 is in the idle state, drive wheel 14 rotates and pushes push rod 8 toward the side closer to the experiment board pad 2, and then moves push rod 8 away from the experiment board pad 2, moving platform 1 toward and away from the experiment board pad 2, enabling the insertion and removal of the microcontroller and tube leg 3. By alternating between the transmission state and the idle state, push rod 8 slides back and forth on workbench 12 multiple times.

[0037] As a further illustration of the above technical solution, multiple carriers 1 are mounted circumferentially on a turntable 9, each extending through and slidably connected to the turntable 9. The carriers 9 slide back and forth axially along the turntable 1. A push rod 8, with one end spherical and removably connected to the carriers 1, is inserted and removed. The rotation of the turntable 9 sequentially moves the multiple carriers 1 between the experimental board pads 2 and the push rod 8. This arrangement improves the continuity and efficiency of microcontroller testing.

[0038] As a further illustration of the above technical solution, a through slot 901 is respectively provided on the turntable 9 at positions corresponding to the multiple carriers 1. The through slots 901 are arranged along the radial direction of the turntable 9. A driving rod 10 is provided in each through slot 901. The driving rod 10 is arranged along the axial direction of the turntable 9.

[0039] A push plate 11 is slidably mounted on the outer circumference of one end of each driving rod 10. One end of each of the push plates 11 faces the multiple carriers 1, and the push plates 11 penetrate into the carriers 1 along the length direction of the slots 101 and extend into the slots 101. When the carriers 1 slide, the push plates 11 slide on the driving rods 10 along with the carriers 1.

[0040] The other ends of the multiple driving rods 10 are respectively slidably connected to the end of the turntable 9 away from the experimental board pad 2, and the sliding directions of the multiple driving rods 10 are respectively parallel to the length directions of the multiple card slots 101, and when the driving rods 10 slide toward the side close to the carrier 1, the push plate 11 is pushed deep into the card slot 101 to push the microcontroller out of the card slot 101. When the driving rods 10 slide toward the side away from the carrier 1, the card slot 101 is restored to a state that can accommodate the microcontroller.

[0041] Furthermore, a pusher block 16 is slidably installed in the workbench 12, and the pusher block 16 slides radially along the turntable 9, and the workbench 12 is exposed on the pusher block 16 at one end facing the turntable 9 and a pusher groove is provided. A pusher plate 17 that cooperates with the pusher groove is fixedly connected to the end of the drive rod 10 facing the workbench 12; through the rotation of the turntable 9, multiple pusher plates 17 enter and exit the pusher groove in turn, and when the pusher plate 17 is located in the pusher groove, the pusher block 16 first slides to the side away from the rotating shaft 91, driving the drive rod 10 to slide toward the carrier 1, pushing the microcontroller out of the slot 101, and then the pusher block 16 slides to the side close to the rotating shaft 91, restoring the slot 101 to a state that can accommodate the microcontroller.

[0042] It should be noted that a second spring 20 is fixed to the other end of the driving rod 10, and the second spring 20 is fixedly connected to the turntable 9. When the pusher block 16 is outside the pusher trough, the second spring 20 keeps the driving rod 10 at a minimum distance from the rotating shaft 91, so that the pusher block 16 can move back into the pusher trough after moving out of the pusher trough.

[0043] The other end of the pushing block 16 is exposed from the workbench 12 and is fixedly connected to a transmission plate 18. A transmission groove 181 is provided at one end of the transmission plate 18, and the transmission groove 181 is inclined. The output end of the motor 13 is also coaxially fixedly connected to a second drive wheel 15, and a cam-shaped drive groove is provided on the second drive wheel 15. A transmission rod 19 is commonly connected between the transmission groove 181 and the drive groove on the second drive wheel 15, and the transmission rod 19 passes through and is slidably connected to the workbench 12. The motor 13 drives the driving wheel 2 15 to rotate, pushing the transmission rod 19 to slide back and forth on the workbench 12, and when the transmission rod 19 slides toward the side close to the turntable 9, the transmission rod 19 pushes the pusher block 16 to slide toward the side away from the rotating shaft 91 through the transmission groove 181. When the transmission rod 19 slides toward the side away from the turntable 9, the transmission rod 19 pushes the pusher block 16 to slide toward the side close to the rotating shaft 91 through the transmission groove 181, thereby realizing the reciprocating sliding of the pusher block 16 relative to the rotating shaft 91, and then realizing the single-chip microcomputer being pushed out of the card slot 101 and restoring the card slot 101 to a state that can accommodate the single-chip microcomputer.

[0044] It should be noted that the driving wheel 14 and the driving wheel 2 15 respectively drive the push rod 8 and the transmission rod 19 to slide back and forth on the workbench 12. The reciprocating sliding of the push rod 8 and the reciprocating sliding of the transmission rod 19 can be carried out simultaneously or staggered, but both must be carried out when the bevel gear installed on the motor 13 is in an idling state.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
