Description

Technical Field

[0001] The invention relates to the technical field of signal processing equipment, in particular to a filter pin inspection device. Background Art

[0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out a specific frequency point in the power line or frequencies other than the frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency. The filter pin refers to the metal part of the filter element used to connect the circuit or other components. They play an important role in electrical connection and signal transmission. When producing the filter, it is often necessary to inspect the flatness of the filter pin. The flatness of the filter pin refers to the flatness of the surface or end of the filter pin during the manufacturing and installation process. The flatness index of the filter pin is crucial to the performance and stability of the filter, because it directly affects the connection quality between the pin and the circuit board or other components, so it is necessary to use an inspection device to strictly detect it.

[0003] The existing method for detecting the flatness of filter pins is to take pictures of several pins through a camera and judge the flatness of the pins based on the pictures. However, this method uses a camera and a display screen to take pictures of the pins and analyze and display them. If the camera and the display screen are damaged, it is expensive to replace the equipment. When the camera takes pictures of the filter, it may not be able to fully capture a larger filter. The lack of flexibility reduces the inspection efficiency of the filter pins. When the filter is moved under the camera, it is often impossible to position the filter, which affects the detection accuracy of the pin flatness. In view of the above problems, the inventor proposes a filter pin inspection device to solve the above problems. Summary of the invention

The sixth connecting shaft 812 is provided with a seventh connecting shaft that is rotatably matched with the top of the inner wall of the L-shaped fixing plate through two second bevel gears meshing with each other. The seventh connecting shaft is driven and matched with the sixth rotating shaft 702 through the third synchronous belt and the third synchronous wheel, so that the rotation of the sixth connecting shaft 812 can drive the sixth rotating shaft 702 to rotate. The seventh spur gear 808 opposite to the fourth sleeve is mounted on the eighth connecting shaft. The eighth connecting shaft is rotatably arranged between the two sixth vertical plates 813. The eighth connecting shaft is provided with a ninth connecting shaft that is also rotatably arranged between the two sixth vertical plates 813 through the fourth synchronous belt and the fourth synchronous wheel.The ninth connecting shaft is provided with a tenth connecting shaft 815 which is rotatably matched with one side of the fourth vertical plate 814 through the fifth synchronous belt and the fifth synchronous wheel. One end of the tenth connecting shaft 815 is fixedly matched with the input end of the second conveyor 3, so that the rotation of the eighth connecting shaft can drive the tenth connecting shaft 815 to rotate, thereby driving the second conveyor 3 to rotate.

[0032] Working principle: when it is necessary to inspect the flatness of the pins of the filter, a plurality of filters waiting for inspection are intermittently placed on the first conveyor 2, and the third motor 804 is started to rotate a quarter of a turn (the first quarter of a turn), thereby driving the four first special-shaped gears 805 to rotate a quarter of a turn in the counterclockwise direction with the first connecting shaft 802 as the axis, thereby driving the second special-shaped gear and the sixth spur gear 807 opposite to the first sleeve to rotate half a turn, thereby driving the seventh spur gear 808 opposite to the first sleeve to rotate one circle with the second connecting shaft 803 as the axis, thereby driving the first rotating shaft 401 to rotate one circle, thereby driving the fourth rotating shaft 405 to rotate one circle, thereby driving the swing plate 408 to swing back and forth, thereby driving the second sliding sleeve to reciprocate one circle along the surface of the guide rod 404, thereby driving the transport plate and the transport suction cup 413 to move one circle, so that the filter adsorbed on the bottom of the transport suction cup 413 moves to the top of the rotating plate 707, thereby completing the filter transport process;

[0033] Start the third motor 804 again to rotate a quarter turn (the second quarter turn), thereby driving the four first special-shaped gears 805 to rotate a quarter turn in the counterclockwise direction with the first connecting shaft 802 as the axis, thereby driving the second special-shaped gear and the sixth spur gear 807 opposite to the second sleeve to rotate half a turn, thereby driving the seventh spur gear 808 opposite to the second sleeve to rotate one turn with the third connecting shaft as the axis, thereby driving the fourth connecting shaft and the fifth connecting shaft to rotate, thereby driving the first conveyor 2 to rotate, so that the new filter waiting for inspection moves to a position opposite to the transport suction cup 413;

[0034] When the filter needs to be positioned so that the center position of the filter coincides with the center of the engaging hole, the second motor 504 is started to rotate the set angle, thereby driving the second spur gear 505 to rotate with the third rotating shaft as the axis, thereby driving the third spur gear 507 to rotate, thereby driving the fixing block 508 to slide along the arc-shaped perforation, thereby driving the second slide bar to slide along the second slide groove, thereby driving the second cylinder 510, the third cylinder 512 and the positioning block 513 to move, so that the four positioning blocks 513 contact the filter and push the filter so that the center of the filter coincides with the center of the engaging hole, thereby completing the positioning operation of the filter;

[0035] When it is necessary to inspect the flatness of the filter pin, the first motor 602 is started to rotate a set number of times, thereby driving the first spur gear 603 to rotate, thereby driving the two first racks 605 to move towards each other, thereby driving the two L-shaped movable plates 604 to approach each other, thereby driving the detection blocks 613 on both sides to approach each other, until the detection block 613 contacts the filter pin, so that the detection block 613 and the movable block 614 move, and the movable block 614 exerts a certain force on the pressure sensor 612. The pressure value sensed by the pressure sensor 612 is transmitted to the control terminal for comparison, thereby realizing the detection of the flatness of the filter pin;

[0036] The third motor 804 is started again to rotate a quarter turn (the third quarter turn), thereby driving the sixth connecting shaft 812 and the seventh connecting shaft to rotate one turn, thereby driving the turntable 703 to rotate one turn with the sixth rotating shaft 702 as the axis, thereby driving the moving bar and the second rack 705 to reciprocate one round, thereby driving the fifth spur gear and the rotating plate 707 to reciprocate one round with the eighth rotating shaft 706 as the axis, so that the inspection completion filter located on the rotating plate 707 passes through the engaging hole and falls steadily on the second conveyor 3;

[0037] Start the third motor 804 again to rotate it a quarter turn (the fourth quarter turn), thereby driving the eighth and ninth connecting shafts to rotate, thereby driving the tenth connecting shaft 815 to rotate, and thereby driving the second conveyor 3 to rotate, so that the filter falling on the second conveyor 3 moves a certain distance to make room for the next filter to continue to fall on the second conveyor 3, and repeat the above process to continuously perform flatness inspection operations on the filter pins.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
