Description

Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to a capacitor height testing machine. Background Art

[0002] A capacitor is an electronic component capable of storing electrical charge. It consists of two conductors (usually called plates) separated by an insulating medium (such as mica, ceramic, or plastic film). During capacitor production, the height of the capacitor is a critical parameter that requires precise measurement.

[0003] The utility model patent with authorization announcement number CN217083713U discloses a height detection device for aluminum electrolytic capacitors. The device includes a conveying mechanism and a detection mechanism. The conveying mechanism includes a bracket and a conveyor belt. The conveyor belt is arranged at the top of the bracket along the length of the bracket. The bracket is provided with a motor for driving the conveyor belt. A support plate is horizontally extended outward from the outer wall of one side of the bracket. A connecting plate is vertically provided on the support plate. The connecting plate has waist-shaped through-holes along the vertical direction. The detection mechanism includes a sensor and a stud. The stud is fixed to the bottom of the sensor. A nut is sleeved on the stud. The sensor is horizontally sleeved on the waist-shaped through-hole on the connecting plate through the stud, with the head of the sensor facing the bracket. By providing the detection mechanism on the bracket, the height of the aluminum electrolytic capacitor can be detected online during the transmission process, improving detection efficiency.

[0004] Although the height detection device for aluminum electrolytic capacitors is convenient for detecting the height of capacitors, the device still has the following problems during detection: when a capacitor with unqualified height is found during the detection process, in order to avoid mixing the capacitor with other capacitors, the staff needs to manually remove the unqualified capacitor separately. However, this method has the disadvantages of inconvenient operation and labor-intensiveness. In view of this, we propose a capacitor height tester. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 5As shown, a capacitor height tester includes a base 1, two side plates 11 are fixed on the top of the base 1, and a notch 110 is opened on the top of each side plate 11; a bracket 12 is installed at the notch 110 on the front side, and a laser distance sensor 13 is installed on the rear end face of the bracket 12 facing the notch 110; two rollers 15 are rotatably installed between the two side plates 11, and a conveyor belt 16 is sleeved between the two rollers 15. A plurality of support blocks 17 are fixed to the outer wall of the conveyor belt 16, and a bracket groove is opened on the top of each support block 17, and a capacitor 18 is placed in each bracket groove; the side plate on the front side A first motor 19 for driving the roller 15 to rotate is installed on the outer wall of 11; a pushing mechanism 2 is installed at the notch 110 on the rear side, and the pushing mechanism 2 includes a fixing frame 20 fixed to the side plate 11, a cavity 201 is opened on the fixing frame 20, a gear 21 is rotatably installed in the cavity 201, and a second motor 22 for driving the gear 21 to rotate is installed on the outer wall of the fixing frame 20; a rack 23 that can move horizontally is engaged above the gear 21, a connecting seat 24 is fixed to the top of the rack 23, and a pushing block 25 inserted into the notch 110 on the rear side is installed at the front end of the connecting seat 24.

[0030] In this embodiment, the bottom of the push block 25 is curved, and the size of the push block 25 is adapted to the size of the groove. The curved bottom of the push block 25 can make the pushing action smoother and reduce jamming; the adapted size ensures that the push block 25 slides smoothly in the groove.

[0031] In this embodiment, a guide rail 241 is fixed to the top of the connecting base 24, and a guide groove is provided on the top of the cavity 201 to be slidably connected to the guide rail 241. The cooperation between the guide rail 241 and the guide groove provides guidance for the movement of the connecting base 24, ensuring the linearity and stability of the movement.

[0032] In this embodiment, the overall shape of the bracket is arcuate, and the size of the bracket is adapted to the size of capacitor 18. The arcuate bracket can better fit the shape of capacitor 18, providing more stable support; the adapted size prevents capacitor 18 from shaking within the bracket, ensuring its accurate and stable position.

[0033] In this embodiment, the overall shape of the bracket 12 is U-shaped, and the laser ranging sensor 13 is fixedly connected to the bracket 12 by bolts. The bolted connection is convenient for installation and removal, and the connection is firm, which makes it easy to maintain and replace the laser ranging sensor 13.

[0034] In this embodiment, a discharge bin 14 is installed below the bracket 12 and is connected to the notch 110. The discharge bin 14 is inclined and guides the ejected unqualified capacitors 18, ensuring that the capacitors 18 fall smoothly into the collection tank 10.

[0035] In this embodiment, a collecting trough 10 is provided on the top of the base 1 and is connected to the discharge bin 14. The collecting trough 10 is convenient for collecting unqualified capacitors 18.

[0036] It should be added that the rear end of the capacitor 18 in this embodiment is in contact with the push block 25. When the laser ranging sensor 13 performs measurement, the laser beam can directly irradiate the front end of the capacitor 18. By utilizing the time-of-flight principle of the laser beam, that is, by measuring the time from the emission to the reflection of the laser, the distance to the target object can be calculated. The distance between the laser ranging sensor 13 and the push block 25 is fixed, so the height of the capacitor 18 is the difference between the straight-line distance between the laser ranging sensor 13 and the push block 25 and the straight-line distance between the laser ranging sensor 13 and the front end of the capacitor 18.

[0037] When in use, the user first turns on the power of the first motor 19, and the first motor 19 starts to work. The output shaft of the first motor 19 rotates to drive the roller 15 to rotate, and the roller 15 drives the conveyor belt 16 to move. The conveyor belt 16 drives the multiple support blocks 17 to move, and the support blocks 17 drive the multiple capacitors 18 to move. When the capacitor 18 moves to the notch 110, the first motor 19 stops working, and then the power of the laser distance sensor 13 is turned on. The laser distance sensor 13 starts to measure and calculate the height of the capacitor 18. When the capacitor 18 moves to the notch 110, the first motor 19 stops working, and then the power of the laser distance sensor 13 is turned on. The laser distance sensor 13 starts to measure and calculate the height of the capacitor 18. 8 is qualified, the conveyor belt 16 continues to move and drives the continuous measurement of multiple capacitors 18; when the height of the capacitor 18 is unqualified, the user turns on the power of the second motor 22, the second motor 22 starts to work, the output shaft of the second motor 22 rotates to drive the gear 21 to rotate, the gear 21 drives the rack 23 and the connecting seat 24 to move horizontally, the connecting seat 24 drives the push block 25 to move horizontally to the front side, the push block 25 removes the unqualified capacitor 18 from the groove, and the capacitor 18 enters the collecting tank 10 through the discharge bin 14 at the same time.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
