Example (b):
as shown in fig. 1 to 4, the present invention provides a capacitor capacity detection device, which includes a feeding mechanism 1, a detection mechanism and a calibration mechanism. The detection mechanism includes a detection circuit, a fixed portion 2, and a slide portion 3 slidable with respect to the fixed portion 2. The capacitor capacity detection device further comprises a frame body 23. The feeding mechanism 1, the detecting mechanism and the calibrating mechanism are all arranged on the frame body 23, so that all the components are combined into a whole. The detection circuit is a conventional capacitor capacity detection circuit, and the structure and principle of the detection circuit are not described in detail in the specification. The fixing portion 2 is fixedly disposed on the frame 23. Both sides of the sliding part 3 are provided with through holes. Two guide rods 17 and a screw 22 are further arranged between the fixing part 2 and the frame body 23; the two guide rods 17 penetrate through the two through holes of the sliding part 3, so that the sliding part 3 can stably slide along the guide rods 17, and the sliding part 3 can slide relative to the fixing part 2; the screw 22 is threadedly coupled to the threaded hole of the sliding portion 3, so that the screw 22 rotates to drive the sliding portion 3 to slide. The frame body 23 is further provided with a driving motor 21 for driving the screw 22 to rotate in order to drive the screw 22 to rotate. The fixed part 2 and the sliding part 3 are each provided with an electrode 4. The electrode 4 of the fixed part 2 and the electrode 4 of the sliding part 3 are arranged oppositely and both are connected to the detection circuit.
The feeding mechanism 1 is matched with the detection mechanism to be arranged, so that the feeding mechanism 1 conveys materials to the detection mechanism. The feeding mechanism 1 may be a conveyor belt. The conveyor belt passes between the fixed portion 2 and the slide portion 3, and the capacitor element 24 on the conveyor belt passes between the fixed portion 2 and the slide portion 3.
The calibration mechanism includes a movable portion 6 and a thrust sensor 5 provided to the movable portion 6. The movable portion 6 is disposed in cooperation with the detection mechanism so that the movable portion 6 can move the thrust sensor 5 to between the fixed portion 2 and the sliding portion 3. When the thrust sensor 5 is located between the fixed portion 2 and the sliding portion 3, the thrust sensor 5 faces the sliding portion 3. At this time, the surface of the thrust sensor 5 is located at a position just at one end of the core 24 when clamped.
When the capacitor capacity detecting device is used, a capacitor core 24 to be detected is conveyed between the fixed part 2 and the sliding part 3 through the feeding mechanism 1. Subsequently, the sliding portion 3 approaches the fixing portion 2, so that the sliding portion 3 and the fixing portion 2 clamp both ends of the core 24. At this time, the electrodes 4 of the sliding portion 3 and the electrodes 4 of the fixing portion 2 are connected to both ends of the core 24, respectively, and the core 24 is connected to the detection circuit. The detection circuit can detect the capacity of the core 24.
After a long time of testing, the moving distance of the sliding part 3 relative to the fixed part 2 may be changed due to mechanical error, and the clamping force at the two ends of the core 24 is changed, so that the capacity of the core 24 is tested inaccurately. Therefore, after a long time use, the movable portion 6 moves between the fixed portion 2 and the slide portion 3, thereby causing the thrust sensor 5 to enter between the fixed portion 2 and the slide portion 3. Subsequently, the sliding portion 3 gradually approaches the fixed portion 2, thereby pressing the thrust sensor 5. When the reading of the thrust sensor 5 reaches a preset value, the current position of the slide 3 is recorded. The slide portion 3 may be moved to this position in the subsequent test. The clamping force exerted by the movement of the slide 3 during the subsequent test is made the same by the straightening. Thereby ensuring that the core 24 is measured under the same clamping conditions and ensuring the accuracy of the measurement.
In this embodiment, the calibration mechanism further includes a base 7 and a lifting device 8 connected to the base 7. The lifting device 8 may be an air cylinder, which can drive the base body 7 to lift. The movable part 6 is slidably disposed on the seat body 7 so as to move the thrust sensor 5 away from or close to the fixed part 2. Specifically, the movable part 6 is provided with a guide rod 17 and a screw 22 in cooperation with the seat body 7; the guide rod 17 is used for guiding the movable part 6, and the screw 22 is connected with the movable part 6 in a threaded manner; the screw 22 is also provided with a drive motor 21 for driving the rotation thereof; the driving motor 21 rotates to drive the movable part 6 to move away from or close to the fixed part 2 through the screw 22. The lifting device 8 is arranged in a way of being matched with the detection mechanism, so that the thrust sensor 5 is driven to enter between the fixed part 2 and the sliding part 3 when the lifting device 8 descends; when the lifting device 8 is lifted, the thrust sensor 5 is driven to be separated from the space between the fixed part 2 and the sliding part 3.
In actual production, the product models are various, and the sizes of the cores 24 are different. When a product is replaced, the distance that the sliding portion 3 needs to slide changes. At this time, it is necessary to calibrate the sliding distance of the sliding portion 3 again to ensure that the clamping force of the core 24 is an appropriate value. In the calibration process, the thrust sensor 5 is firstly lowered between the fixed part 2 and the sliding part 3 through the lifting device 8; subsequently, the driving motor 21 of the movable portion 6 drives the movable portion 6 to move so that the distance between the end surface of the thrust sensor 5 and the electrode 4 of the fixed portion 2 is the same as the length of the core 24 at present. Finally, the sliding part 3 slides and records the current position of the sliding plate when the thrust force from the sliding part 3 received by the thrust sensor 5 is the clamping force of the core 24. This position is the slide position of the slide 3 at the time of the subsequent measurement. Thereby completing the calibration. After the calibration is completed, the lifting device 8 is lifted up so that the thrust sensor 5 is withdrawn between the fixed part 2 and the sliding part 3.
The movable portion 6 is provided to simulate the position state of the core 24 between the fixed portion 2 and the slide portion 3. The cooperation of the lifting device 8 and the movable part 6 can conveniently and quickly adjust the sliding distance of the sliding part 3 after the product is replaced.
In this embodiment, the fixed portion 2 is provided with a plurality of electrodes 4. A plurality of electrodes 4 are distributed along the conveying direction of the feeding mechanism 1. The sliding part 3 is provided with a group of clamping components respectively facing the electrodes 4 of the fixed part 2. The clamping assembly comprises a push rod 9, a push spring 10 and a sliding sleeve 11. The push rod 9 is slidably inserted into the sliding sleeve 11. The pushing spring 10 is disposed between the push rod 9 and the sliding sleeve 11, so that the pushing spring 10 is gradually compressed when the push rod 9 extends into the sliding sleeve 11. The sliding sleeve 11 is slidably disposed on the sliding portion 3 and a sliding direction of the sliding sleeve 11 relative to the sliding portion 3 is parallel to a connecting line of the fixing portion 2 and the sliding portion 3. The sliding portion 3 is provided with one electrode 4 for each electrode 4 of the fixed portion 2. Each electrode 4 of the slide 3 is provided at the front end of one push rod 9.
The plurality of electrodes 4 of the fixed part 2 correspond to the plurality of electrodes 4 of the sliding part 3, and a plurality of groups of clamping components are arranged, so that the capacities of the plurality of cores 24 can be tested simultaneously. In practice the same wick 24 may be measured separately as it passes over the sets of electrodes 4. The system can more accurately obtain the capacity of the core 24 by algorithms such as averaging according to the results of multiple measurements. It is also possible to put a plurality of wicks 24 at once and make each wick 24 correspond to a set of electrodes 4. This makes the sliding part 3 act once to measure a plurality of cores 24, improves efficiency, and is more suitable for mass production in factories.
When the plunger 9 pushes the core 24, the push spring 10 is compressed. Due to the differences in mechanical properties of each set of clamping assemblies, the clamping force applied uniformly through the slipper 3 may result in non-uniform clamping force per core 24. The push rod 9 and the push-up spring 10 are provided and the push rod 9 and the push-up spring 10 are engaged with the slide sleeve 11. The clamping force of the push rod 9 on the core 24 when the sliding part 3 stops pushing can be adjusted by adjusting the position of the sliding sleeve 11 relative to the sliding part 3. Thereby ensuring that the thrust output by each group of clamping components can not fluctuate due to the difference of the mechanical properties when the sliding part 3 advances.
In this embodiment, the sliding portion 3 is provided with a plurality of sliding holes. A plurality of sliding sleeves 11 are respectively arranged in one sliding hole in a penetrating way, so that the sliding sleeves 11 can slide in the sliding holes. The sliding portion 3 is also provided with a transmission gear 12 in cooperation with each sliding sleeve 11. The transmission gear 12 is rotatably provided in the sliding portion 3. The transmission gear 12 is provided with an internal thread. The sliding sleeve 11 is provided with an external thread matching with the transmission gear 12.
The calibration mechanism is also provided with an adjustment motor 13. The adjusting motor 13 is arranged on the seat body 7. The adjustment motor 13 is also provided with a drive gear 14 in cooperation with the transmission gear 12, so that the drive gear 14 is engaged with the transmission gear 12 when the thrust sensor 5 is located between the fixed portion 2 and the sliding portion 3. The base 7 is further provided with a drive means 15 for driving the base to move along the length of the fixing part 2.
When calibration is performed, the movable part 6 is adjusted in position by the corresponding driving motor 21; at the same time, the lifting device 8 is lowered so that the transmission gear 12 and the drive gear 14 are engaged. The adjustment motor 13 rotates to drive the transmission gear 12 to rotate, so that the sliding sleeve 11 moves relative to the sliding part 3. Meanwhile, the driving device 15 drives the seat body 7 to move, so that the movable part 6 and the driving gear 14 correspond to different groups of clamping assemblies and driving gears 14, and each group of clamping assemblies is calibrated one by one. This also makes the product change back, and the calibration of a plurality of centre gripping subassemblies can automatic go on, avoids the trouble that manual adjustment brought.
In order to prevent the sliding sleeve 11 from rotating along with the rotation of the transmission gear 12, a plurality of limiting grooves 111 are formed in the outer wall of the sliding sleeve 11 along the length direction of the sliding sleeve. The hole wall of the sliding hole is provided with a limiting block in cooperation with the limiting groove 111, so that the limiting block is accommodated in the limiting groove 111 when the sliding sleeve 11 is inserted into the sliding hole.
In this embodiment, the alignment mechanism further includes a mounting plate 16. The mounting plate 16 is connected to the frame body 23 by a rail so that the mounting plate 16 can slide along the rail. The lifting device 8 is a cylinder. The cylinder is provided to the mounting plate 16. The telescopic rod of the cylinder is connected with the seat body 7. The seat body 7 is provided with a guide rod 17 in cooperation with the mounting plate 16. The driving device 15 is in transmission connection with the mounting plate 16. The driving device 15 may employ a conventional lead screw pair and motor to enable the driving device 15 to drive the mounting plate 16 to slide along the rail.
In this embodiment, the end of the feeding mechanism 1 is further provided with a pushing rod 19. The material returning rod can adopt an air cylinder, and the front end of the telescopic rod is provided with a push plate. The pushing direction of the pushing rod 19 is along the horizontal direction and perpendicular to the feeding direction of the feeding mechanism 1. When the capacity of the core 24 is unqualified through detection, the core 24 is pushed by the material returning rod to leave the feeding mechanism 1 when passing through the material pushing rod 19, so that unqualified products are separated, and the subsequent processing aiming at the unqualified core 24 is avoided.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
