This device for detecting the withstand voltage of a capacitor metallized film can drive the second driving roller to rotate by using the design of the first driving roller and the first transmission belt. By the rotation of the second driving roller, it is convenient to synchronously drive the bottom screw connected thereto to rotate. Thus, the connecting sleeve plate, the connecting plate and the pushing plate on the outer surface of the bottom screw will move along the transverse direction of the bottom screw, facilitating the pushing of the capacitor to be detected placed inside the loading frame, i.e., on one side of the pushing plate, to the lower part of the placing plate.

[0017] 2. The withstand voltage detection device for the metallized film of the capacitor adopts closed feeding. In the case of closed feeding, it is beneficial to reduce the interference factors during the capacitor detection, and can improve the safety effect and simultaneously improve the accuracy of the capacitor detection. The design of the insulating gloves can place the user's hand in it, facilitating the user to operate the detection head of the withstand voltage tester to connect with the capacitor through the insulating gloves. After connection, the design of the withstand voltage tester applies a DC or AC voltage with a rated voltage to both ends of the capacitor and maintains it for a period of time. If the current flowing through the capacitor exceeds the set value or the capacitor breaks down during the test, it is determined that the withstand voltage is unqualified.

[0018] 3. The withstand voltage detection device for the metallized film of the capacitor can drive the second conveyor belt and the third transmission roller to rotate by the rotation of the drive shaft, thereby synchronously driving the overhead screw to rotate. When the overhead screw rotates, the connecting sleeve plate and the cleaning plate move horizontally along the outer surface of the bottom of the upper viewing window, facilitating the periodic cleaning of the inner surface of the upper viewing window during the loading and unloading of the capacitor, and avoiding the influence on the viewing line of the upper viewing window during the capacitor detection.

[0022] As Figures 1-6As shown in the figure, the present invention provides a technical solution: a withstand voltage detection device for a capacitor metallized film, including an upper frame 1, an upper viewing window 2, insulating gloves 3, a withstand voltage tester 4, a side frame 5, a baffle 6, a lower frame 7, a side viewing window 8, a loading frame 9, a fixing plate 10, an internal groove 11, a cleaning component 12, a top screw 1201, a cleaning plate 1202, a connecting sleeve plate 1203, an auxiliary component 13, a bottom screw 1301, a connecting sleeve plate 1302, a connecting plate 1303, a pushing plate 1304, a limiting component 14, a side plate 1401, a pneumatic rod 1402, a positioning plate 1403, a rubber pad 1404, a placing plate 15, a driving component 16, a servo motor 1601, a driving shaft 1602, an assembly plate 1603, a first driving roller 17, a first transmission belt 18, a second driving roller 19, a loading component 20, a loading auxiliary frame 2001, a loading plate 2002, a threaded rod 2003, an end plate 2004, a second transmission belt 21 and a third driving roller 22. An internal groove 11 is opened at the bottom of the upper frame 1, and a withstand voltage tester 4 is arranged on one side of the outer surface of the internal groove 11. Insulating gloves 3 are installed on both sides inside the upper frame 1, and the insulating gloves 3 are arranged above the withstand voltage tester 4. The placing plate 15 is arranged on one side outside the withstand voltage tester 4, and two groups of placing plates 15 are installed. A driving component 16 for adjusting the position of the placing plate 15 is arranged on one side of the two groups of placing plates 15. The driving component 16 includes a servo motor 1601, a driving shaft 1602 and an assembly plate 1603. The output end of the servo motor 1601 is installed with a driving shaft 1602, and an assembly plate 1603 is arranged at the end of the driving shaft 1602. A first driving roller 17 is arranged on the outer surface of the driving shaft 1602 near one side of the servo motor 1601, and a first transmission belt 18 is installed on the outer surface of the first driving roller 17. A second driving roller 19 is arranged on one side surface at the bottom of the first transmission belt 18, and an auxiliary component 13 for assisting in loading is installed at one end of the second driving roller 19. The auxiliary component 13 includes a bottom screw 1301, a connecting sleeve plate 1302, a connecting plate 1303 and a pushing plate 1304. The connecting sleeve plate 1302 is threadedly installed on the outer surface of the bottom screw 1301. A connecting plate 1303 is installed on one side of the connecting sleeve plate 1302, and a pushing plate 1304 is arranged at the end of the connecting plate 1303. The end of the bottom screw 1301 is provided with a loading frame 9, and a loading component 20 for closing the loading is installed inside the loading frame 9. The loading component 20 includes a loading auxiliary frame 2001, a loading plate 2002, a threaded rod 2003 and an end plate 2004. The loading plate 2002 is slidably installed inside the loading auxiliary frame 2001, and a threaded rod 2003 is rotatably arranged on one side of the loading plate 2002. The end plate 2004 is threadedly installed on the outer surface of one side of the threaded rod 2003. Through the design of the servo motor 1601, the driving shaft 1602 can be driven to rotate. Through the rotation of the servo motor 1601, the assembly plate 1603 and the placing plate 15 can be driven to flip, facilitating the position replacement of the two groups of placing plates 15.It is beneficial to use the limiting component 14 in the placement plate 15 to clamp and load the capacitor to be detected. When the drive shaft 1602 rotates, the design of the first transmission roller 17 and the first transmission belt 18 can drive the second transmission roller 19 to rotate. The rotation of the second transmission roller 19 facilitates synchronously driving the bottom screw 1301 connected thereto to rotate. Thus, the connecting sleeve plate 1302, the connecting plate 1303, and the pushing plate 1304 on the outer surface of the bottom screw 1301 will move along the transverse direction of the bottom screw 1301, which is convenient for pushing the capacitor to be detected placed inside the loading frame 9, i.e., on one side of the pushing plate 1304, to the lower part of the placement plate 15. Additionally, the capacitor to be detected is pre-placed inside the auxiliary loading frame 2001. Due to the visible design of the auxiliary loading frame 2001 and the loading frame 9 for the user, the threaded rod 2003 inside the end plate 2004 can be rotated. By rotating the threaded rod 2003, the loading plate 2002 can be driven to slide inside the auxiliary loading frame 2001, which is convenient for loading the capacitor pre-stored inside the auxiliary loading frame 2001 to one side of the pushing plate 1304 without opening the entire detection device, facilitating the loading and detection of the capacitor when the placement plate 15 is flipped. Secondly, the number of the loading components 20 can be selectively installed with respect to the loading frame 9 according to the usage requirements. In the case of closed loading, it is beneficial to reduce the interference factors during the capacitor detection, and it can improve the safety effect and simultaneously improve the accuracy of the capacitor detection. The insulating gloves 3 can be designed to place the user's hand therein, which is convenient for the user to operate the detection head of the withstand voltage tester 4 to connect with the capacitor through the insulating gloves 3. After connection, through the design of the withstand voltage tester 4, a DC or AC voltage with a rated voltage is applied across the capacitor and maintained for a period of time. If the current flowing through the capacitor exceeds the set value during the test, or the capacitor breaks down, it is determined that the withstand voltage is unqualified.

[0023] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a fixed plate 10 is installed on the outer side of one side of the loading frame 9, and a loading auxiliary frame 2001 is snap-fitted on one side of the loading frame 9. A top view window 2 is provided on the top of the upper frame 1. A cleaning component 12 for assisting in cleaning the top view window 2 is provided on the outer surface of the bottom of the top view window 2. The cleaning component 12 includes a top screw 1201, a cleaning plate 1202, and a connecting sleeve plate 1203. A connecting sleeve plate 1203 is threadedly installed on the outer surface of the top screw 1201, and a cleaning plate 1202 is provided on one side of the connecting sleeve plate 1203. The cleaning plate 1202 is slidably arranged on the outer surface of the bottom of the top view window 2. One end of the top screw 1201 is installed with a third driving roller 22, and a second transmission belt 21 is provided on the outer surface of the third driving roller 22. By rotating the driving shaft 1602, the second transmission belt 21 and the third driving roller 22 can be driven to rotate, so that the top screw 1201 can be synchronously driven to rotate. When the top screw 1201 rotates, the connecting sleeve plate 1203 and the cleaning plate 1202 move horizontally along the outer surface of the bottom of the top view window 2, which is convenient for periodically cleaning the inner surface of the top view window 2 during the process of loading and unloading capacitors, and avoiding the influence on the observation line of the top view window 2 when detecting the capacitors. The length of the cleaning plate 1202 coincides with the width of the upper frame 1. Side view windows 8 are installed on both sides of the lower frame 7. Side frames 5 are provided on both sides of the upper frame 1, and a baffle 6 is snap-fitted on one side of the side frame 5. Through the design of the top view window 2, the effect of protecting the eyes is achieved, and it is also convenient for the user to observe the detection situation of the capacitors. Through the design of the withstand voltage tester 4, a DC or AC voltage with a rated voltage is applied to both ends of the capacitor and maintained for a period of time. If the current flowing through the capacitor exceeds the set value during the test, or the capacitor breaks down, it is determined that the withstand voltage is unqualified. The unqualified capacitors can be driven by the rotation of the servo motor 1601 to drive the assembly plate 1603 and the placement plate 15 to flip, which is beneficial to transfer the capacitors after detection in the placement plate 15 to the inside of the side frame 5. And there are two groups of side frames 5, which is convenient for classifying and storing qualified capacitors or unqualified capacitors.

[0024] As Figure 4 and Figure 5 shown in the figure, a limiting component 14 for limiting the capacitors is provided on the outer surface of the placement plate 15, and two groups of limiting components 14 are installed. The limiting component 14 includes a side plate 1401, a pneumatic rod 1402, a positioning plate 1403, and a rubber pad 1404. A pneumatic rod 1402 is installed on the outer surface of the side plate 1401, a positioning plate 1403 is installed at the output end of the pneumatic rod 1402, and a rubber pad 1404 is provided on the outer surface of the positioning plate 1403. Through the design of the side plate 1401 and the pneumatic rod 1402, the position of the positioning plate 1403 can be driven to move. By moving the position of the positioning plate 1403, it is convenient to limit the capacitors pushed into the lower frame 7, which is beneficial to automatically and stably load the capacitors to be detected.

[0025] In summary, as Figures 1-6As shown, for this capacitor metallized film withstand voltage detection device, during use, the design of the servo motor 1601 can drive the drive shaft 1602 to rotate. Through the rotation of the servo motor 1601, the assembly plate 1603 and the placement plate 15 can be driven to flip, facilitating the replacement of the positions of the two placement plates 15. This is beneficial for using the limiting component 14 in the placement plate 15 to clamp and load the capacitors to be detected. Moreover, when the drive shaft 1602 rotates, the design of the first transmission roller 17 and the first transmission belt 18 can be used to drive the second transmission roller 19 to rotate. Through the rotation of the second transmission roller 19, it is convenient to synchronously drive the bottom-mounted screw rod 1301 connected thereto to rotate. As a result, the connecting sleeve plate 1302, the connecting plate 1303, and the pushing plate 1304 on the outer surface of the bottom-mounted screw rod 1301 will move along the horizontal direction of the bottom-mounted screw rod 1301, facilitating the pushing of the capacitors to be detected placed inside the loading frame 9, i.e., on one side of the pushing plate 1304, to the lower part of the placement plate 15. Additionally, the capacitors to be detected are pre-placed inside the auxiliary loading frame 2001. With the visible design of the auxiliary loading frame 2001 and the loading frame 9 for the user, the threaded rod 2003 inside the end plate 2004 can be rotated. Through the rotation of the threaded rod 2003, the loading plate 2002 can be driven to slide inside the auxiliary loading frame 2001, facilitating the loading of the capacitors pre-stored inside the auxiliary loading frame 2001 to one side of the pushing plate 1304 without opening the entire detection device, facilitating the loading and detection of the capacitors when the placement plate 15 is flipped. Secondly, the number of the loading components 20 can be selectively installed on the loading frame 9 according to the usage requirements. In the case of closed loading, it is beneficial to reduce the interference factors during the capacitor detection, and can improve the safety effect while simultaneously improving the accuracy of the capacitor detection. The design of the insulating gloves 3 can be used to place the user's hand therein, facilitating the user to operate the detection head of the withstand voltage tester 4 to connect with the capacitor through the insulating gloves 3. After connection, through the design of the withstand voltage tester 4, a DC or AC voltage of the rated voltage is applied to both ends of the capacitor and maintained for a period of time. If the current flowing through the capacitor exceeds the set value during the test, or the capacitor breaks down, it is determined that the withstand voltage is unqualified. The fixation of the capacitor by the placement plate 15 is that through the design of the side plate 1401 and the air rod 1402, the position of the positioning plate 1403 can be driven to move. Through the position movement of the positioning plate 1403, it is convenient to limit the capacitors pushed into the lower frame 7. During the detection process, the rotation of the drive shaft 1602 can drive the second transmission belt 21 and the third transmission roller 22 to rotate, thereby synchronously driving the top-mounted screw rod 1201 to rotate. When the top-mounted screw rod 1201 rotates, the connecting sleeve plate 1203 and the cleaning plate 1202 move horizontally along the outer surface of the bottom of the upper viewing window 2, facilitating the periodic cleaning of the inner surface of the upper viewing window 2 during the process of loading and unloading the capacitors, avoiding the influence on the observation line of sight of the upper viewing window 2 when detecting the capacitors. After detection, through the design of the upper viewing window 2, it plays a protective role, and is also convenient for the user to observe the detection situation of the capacitors.Through the design of the withstand voltage tester 4, a DC or AC voltage of the rated voltage is applied across the capacitor and maintained for a period of time. If during the test, the current flowing through the capacitor exceeds the set value, or the capacitor breaks down, it is determined that the withstand voltage is unqualified. The unqualified capacitor can drive the assembly plate 1603 and the placement plate 15 to flip through the rotation of the servo motor 1601, which is beneficial to transfer the capacitor after detection in the placement plate 15 to the inside of the side frame 5. And there are two groups of side frames 5, which is convenient for classifying and storing qualified capacitors or unqualified capacitors.
