Description

Technical Field

[0001] The utility model relates to the technical field of the production of horn-shaped aluminum electrolytic capacitors, in particular to a device for detecting capacitor short circuits. Background Technique

[0002] The horn-shaped aluminum electrolytic capacitor mainly consists of three parts: electrolyte, positive and negative electrode plates, and an aluminum shell. Its design enables space savings during installation and is suitable for use in environments with limited space. The capacitance detection of the horn-shaped aluminum electrolytic capacitor is an important link, which involves multiple aspects of testing to ensure the quality and performance of the capacitor. During the production of horn-shaped aluminum electrolytic capacitors, after inserting the rows, the row rack is placed in the charging position inside the aging oven, and charging and aging can only start after all the products in this batch are inserted. During this period, the equipment is in a standby state for a long time, resulting in a large time cost and affecting the capacitance detection efficiency of the horn-shaped aluminum electrolytic capacitor. Some devices for detecting capacitor short circuits use a specific diameter of the clamping unit to clamp horn-shaped aluminum electrolytic capacitors with a specific diameter, which limits the applicable clamping range of the horn-shaped aluminum electrolytic capacitors for the device for detecting capacitor short circuits and restricts the capacitance detection efficiency of the horn-shaped aluminum electrolytic capacitor. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a device for detecting capacitor short circuits, which can realize the adaptive and stable clamping of horn-shaped aluminum electrolytic capacitors with different diameters. At the same time, through the plug-in row mode composed of a DC power switch, the capacitance short circuit detection of the horn-shaped aluminum electrolytic capacitor after plugging in the row is realized, greatly saving the working time of capacitance short circuit detection, and effectively solving the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A device for detecting capacitor short circuits, including an aging oven;

[0005] Aging oven: Three fixed frames are fixedly connected inside it. The upper surfaces of the fixed frames are all provided with evenly distributed contact circuits. The upper ends of the fixed frames are all provided with plug-in row racks. The inside of the plug-in row racks is provided with evenly distributed plug-in row holes. The plug-in row holes are vertically corresponding to the contact heads of the vertically adjacent contact circuits. A working chamber is arranged at the left end of the aging oven. A DC power switch is arranged inside the working chamber. The input ends of the contact circuits are all electrically connected to the output end of the DC power switch. A controller is arranged in the middle of the left side surface of the aging oven. The input end of the DC power switch is electrically connected to the output end of the controller. The input end of the controller is electrically connected to an external power supply, which can realize the adaptive and stable clamping of horn-shaped aluminum electrolytic capacitors with different diameters. At the same time, through the plug-in row mode composed of a DC power switch, the capacitance short circuit detection of the horn-shaped aluminum electrolytic capacitor after plugging in the row is realized, greatly saving the working time of capacitance short circuit detection.

[0006] Furthermore, it further includes an adaptive clamping mechanism. The adaptive clamping mechanism includes telescopic columns, clamping plates, and springs. The telescopic columns are fixedly connected to the front ends of the socket holes. The telescopic ends of the telescopic columns are fixedly connected with clamping plates. Springs are fixedly connected between the clamping plates and the corresponding front ends of the socket holes. The springs are movably sleeved on the outer surfaces of the telescopic columns, realizing the adaptive and stable clamping of horn-shaped aluminum electrolytic capacitors with different diameters.

[0007] Furthermore, sliding rails are arranged at both the left and right ends of the fixing frame. Positioning holes are arranged at both the front and rear ends of the sliding rails. The lower end of the socket rack is fixedly connected with symmetrically distributed insertion posts. The insertion posts are all slidably connected with the vertically adjacent sliding rails, and the insertion posts are all inserted into the vertically corresponding positioning holes, facilitating the installation and fixation of the socket rack.

[0008] Furthermore, a heating chamber is arranged at the rear end of the aging oven. Three installation slots are arranged between the heating chamber and the aging oven. Uniformly distributed heating pipes are arranged inside the installation slots. Three fan slots are arranged at the rear end of the heating chamber. Fans are arranged inside the fan slots. The input ends of the heating pipes and the fans are electrically connected to the output end of the controller, providing a heat source for the aging of horn-shaped aluminum electrolytic capacitors.

[0009] Furthermore, a display screen is arranged at the upper end of the left surface of the aging oven. The input end of the display screen is electrically connected to the output end of the controller, displaying the capacitance detection status of the horn-shaped aluminum electrolytic capacitors in the socket.

[0010] Furthermore, symmetrically distributed handles are fixedly connected to the upper end of the socket rack. The handles are all rubber handles, facilitating personnel to move the socket rack.

[0011] Furthermore, a chamber door is hinged to the front end of the aging oven. An observation window is arranged at the upper end of the chamber door, closing the aging oven.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: This device for detecting capacitor short circuits has the following advantages:

[0013] 1. Personnel move the socket strip rack through the handle and place the socket strip rack on the upper end of the corresponding fixed rack in sequence, so that the insertion posts all slide backward inside the corresponding slide rails. When the insertion posts all move to the upper end of the corresponding positioning holes, personnel plug the insertion posts into the corresponding positioning holes through the handle, thereby realizing the position locking between the socket strip rack and the vertically adjacent fixed rack. Then, personnel plug the horn-shaped aluminum electrolytic capacitors to be detected into the socket holes in sequence. When the horn-shaped aluminum electrolytic capacitors enter the socket holes, the horn-shaped aluminum electrolytic capacitors push the longitudinally adjacent clamping plates to move forward. The forward movement of the clamping plates causes the telescopic ends of the longitudinally adjacent telescopic columns to contract, and at the same time causes the longitudinally adjacent springs to be elastically compressed. The elastic force of the springs reacts on the longitudinally adjacent clamping plates, thereby realizing the stable clamping of the horn-shaped aluminum electrolytic capacitors through the clamping plates. Through the cooperation of the spring elastic force and the telescopic columns, the adaptive stable clamping of the horn-shaped aluminum electrolytic capacitors with different diameters is realized, greatly expanding the applicable range of the capacitance short-circuit detection of the horn-shaped aluminum electrolytic capacitors.

[0014] 2. During the process of personnel inserting the horn-shaped aluminum electrolytic capacitors into the socket, the horn-shaped aluminum electrolytic capacitors are all in contact with the contact heads of the vertically adjacent contact circuits. At the same time, the controller realizes the operation of the DC power switch. The DC power switch supplies power to the contact circuit, and starts to charge the product with low voltage and large current. At the same time, the controller realizes the operation of the display screen. Normal products will display green at the corresponding workstations, and short-circuited products will display yellow for easy distinction, thereby realizing the rapid capacitance detection of the horn-shaped aluminum electrolytic capacitors. At the same time, through the socket mode formed by the DC power switch, the capacitance short-circuit detection of the horn-shaped aluminum electrolytic capacitors after socketing is realized. When the horn-shaped aluminum electrolytic capacitors are short-circuited, they can be discovered and corrected in time, greatly saving the working time of the capacitance short-circuit detection.

[0020] Please refer to Figures 1 - 3 , this embodiment provides a technical solution: a device for detecting capacitor short circuits, including an aging oven 1;

[0021] Aging oven 1: Three fixed frames 3 are fixedly connected inside it. The upper surfaces of the fixed frames 3 are all provided with evenly distributed contact circuits 9. The upper ends of the fixed frames 3 are all provided with socket racks 4. The inside of the socket racks 4 is provided with evenly distributed socket holes 6. The socket holes 6 are vertically corresponding to the contact heads of the vertically adjacent contact circuits 9. A working chamber 10 is provided at the left end of the aging oven 1. A DC power switch 11 is provided inside the working chamber 10. The DC power switch 11 is a 24V 15A DC power switch. The input ends of the contact circuits 9 are all electrically connected to the output end of the DC power switch 11. A controller 17 is provided in the middle of the left side surface of the aging oven 1. The input end of the DC power switch 11 is electrically connected to the output end of the controller 17. The input end of the controller 17 is electrically connected to an external power supply. A chamber door 12 is hinged to the front end of the aging oven 1. An observation window is provided at the upper end of the chamber door 12. During the process of inserting the horn-type aluminum electrolytic capacitor into the socket, the horn-type aluminum electrolytic capacitors are all in contact with the contact heads of the vertically adjacent contact circuits 9. At the same time, the DC power switch 11 is operated through the controller 17. The DC power switch 11 supplies power to the contact circuits 9, and starts to charge the product with low voltage and large current. At the same time, the controller 17 enables the display screen 14 to operate. Normal products will display green at the corresponding workstations, and short-circuited products will display yellow for easy distinction, thereby realizing the rapid capacitance detection of the horn-type aluminum electrolytic capacitor. At the same time, through the socket mode constituted by the DC power switch, the capacitance short-circuit detection of the horn-type aluminum electrolytic capacitor after inserting the socket is realized;

[0022] Among them: It further includes an adaptive clamping mechanism 5. The adaptive clamping mechanism 5 includes telescopic columns 51, clamping plates 52 and springs 53. The telescopic columns 51 are all fixedly connected to the front ends of the socket holes 6. The telescopic ends of the telescopic columns 51 are all fixedly connected with clamping plates 52. Springs 53 are fixedly connected between the clamping plates 52 and the front ends of the corresponding socket holes 6. The springs 53 are all movably sleeved on the outer surfaces of the telescopic columns 51;

[0023] Wherein: Slide rails 7 are provided at both the left and right ends of the fixing frame 3. Positioning holes are provided at both the front and rear ends of the slide rails 7. Symmetrically distributed insertion posts 8 are fixedly connected to the lower end of the socket row frame 4. The insertion posts 8 are all slidably connected to the vertically adjacent slide rails 7, and the insertion posts 8 are all inserted into the vertically corresponding positioning holes. Symmetrically distributed handles 13 are fixedly connected to the upper end of the socket row frame 4. The handles 13 are all rubber handles. The socket row frame 4 is moved through the handles 13, and the socket row frame 4 is successively placed on the upper end of the corresponding fixing frame 3, so that the insertion posts 8 all slide backward inside the corresponding slide rails 7. When the insertion posts 8 all move to the upper end of the corresponding positioning holes, the insertion posts 8 are all inserted into the corresponding positioning holes through the handles 13, thereby realizing the position locking between the socket row frame 4 and the vertically adjacent fixing frame 3. Then, the horn-shaped aluminum electrolytic capacitors to be detected are successively inserted into the socket holes 6. When the horn-shaped aluminum electrolytic capacitors enter the socket holes 6, the horn-shaped aluminum electrolytic capacitors push the longitudinally adjacent clamping plates 52 to move forward. The forward movement of the clamping plates 52 causes the telescopic ends of the longitudinally adjacent telescopic columns 51 to converge, and at the same time causes the longitudinally adjacent springs 53 to be elastically compressed. The elastic force of the springs 53 reacts on the longitudinally adjacent clamping plates 52, thereby realizing the stable clamping of the horn-shaped aluminum electrolytic capacitors through the clamping plates 52;

[0024] Wherein: A heating chamber 2 is provided at the rear end of the aging oven 1. Three installation grooves are provided between the heating chamber 2 and the aging oven 1.

[0025] Wherein: A display screen 14 is provided at the upper end of the left surface of the aging oven 1. The input end of the display screen 14 is electrically connected to the output end of the controller 17.

[0026] The working principle of a device for detecting capacitor short - circuit provided by the utility model is as follows: During operation, first, the operator stably places the aging oven 1, the heating chamber 2 and other mechanisms on the horizontal working area. After the placement is stable, the operator moves the socket rack 4 through the handle 13 and places the socket rack 4 on the upper end of the corresponding fixed rack 3 in sequence, so that the insertion posts 8 all slide backward inside the corresponding slide rails 7. When the insertion posts 8 all move to the upper end of the corresponding positioning holes, the operator inserts the insertion posts 8 into the corresponding positioning holes through the handle 13, thereby realizing the position locking between the socket rack 4 and the vertically adjacent fixed rack 3. Then, the operator inserts the to - be - detected horn - type aluminum electrolytic capacitors into the socket holes 6 in sequence. When the horn - type aluminum electrolytic capacitors enter the socket holes 6, the horn - type aluminum electrolytic capacitors push the longitudinally adjacent clamping plates 52 to move forward. The forward movement of the clamping plates 52 causes the telescopic ends of the longitudinally adjacent telescopic columns 51 to contract, and at the same time causes the longitudinally adjacent springs 53 to be elastically compressed. The elastic force of the springs 53 acts on the longitudinally adjacent clamping plates 52 in the reverse direction, thereby realizing the stable clamping of the horn - type aluminum electrolytic capacitors through the clamping plates 52. At the same time, the horn - type aluminum electrolytic capacitors are all in contact with the contact heads of the vertically adjacent contact circuits 9. At the same time, the controller 17 enables the DC power switch 11 to operate. The DC power switch 11 supplies power to the contact circuit 9, and starts to charge the product with low voltage and large current. At the same time, the controller 17 enables the display screen 14 to operate. Normal products will display green at the corresponding workstations, and short - circuited products will display yellow for easy distinction, thereby realizing the rapid capacitance detection of the horn - type aluminum electrolytic capacitors. Then, the operator enables the fan 16 and the heating tube 15 to operate through the controller 17 to provide heat for the aging of the horn - type aluminum electrolytic capacitors.

[0027] It should be noted that the methods for the controller 17 to control the DC power switch 11, the display screen 14, the heating tube 15 and the fan 16 to work in the above - mentioned embodiments are all commonly used methods in the prior art.
