DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited. Example 1

[0018] A multi-angle detection device for electrolytic capacitor production, such as Figure 1-Figure 5 and Figure 7 As shown, it includes a frame 1, a controller 2 and a multi-channel withstand voltage tester 3; the frame 1 is hinged with a door 101; the door 101 is bolted with a handle 102; the frame 1 is bolted with a controller 2 for controlling all electric drive parts of the device; the frame 1 is bolted with a multi-channel withstand voltage tester 3 for performing withstand voltage detection on a capacitor body 12; It also includes a disc 4, a connecting rod 5, a mounting plate 6, a spring member 7, an alligator clip 8, a conductive clamp 9, an L-shaped push plate 10, a short rod 11 and a pushing assembly; the frame 1 is rotatably connected to four discs 4 for holding the capacitor body 12; each disc 4 is provided with two circular holes 401 distributed left and right; each disc 4 is fixedly connected to four connecting rods 5 distributed in a rectangular shape; two connecting rods 5 on each disc 4 that are symmetrical in front and back are commonly connected to a mounting plate 6; each connecting rod 5 is sleeved with a spring member 7 , and each spring member 7 is fixedly connected to the corresponding disc 4 and the mounting plate 6; each mounting plate 6 is fixedly connected to an alligator clip 8; the two clamping arms of each alligator clip 8 are fixedly connected to a conductive clamping plate 9, and the multi-channel withstand voltage tester 3 and the conductive clamping plate 9 are electrically connected through wires; each disc 4 is slidably connected to an L-shaped push plate 10; each L-shaped push plate 10 is fixedly connected to two short rods 11, and each short rod 11 is in contact with the clamping arm of the corresponding alligator clip 8; the frame 1 is connected to a pushing assembly.

[0019] The pushing assembly includes an electric push rod 111 and a frame-shaped push plate 112; the frame 1 is bolted with four electric push rods 111 distributed in a rectangular shape; the telescopic parts of all the electric push rods 111 are commonly fixed with a frame-shaped push plate 112 for pushing the installation plate 6 and the parts connected thereto to move, and the frame-shaped push plate 112 is in contact with all the installation plates 6.

[0020] The circular hole 401 is in a truncated cone shape, which is used to better insert the metal pin 13 into the circular hole 401 .

[0021] The specific work is as follows: It should be noted in advance that all the electric drive parts of this equipment are controlled by controller 2. The following description is based on Figure 1 is the viewing angle reference, Figure 1 The side where the controller 2 is marked is the front, and the side where the rack 1 is marked is the left; looking from left to right, the conductive clamps 9 arranged on the odd-numbered mounting plates 6 are all connected to the negative port of the multi-channel withstand voltage tester 3 through wires, and the conductive clamps 9 arranged on the even-numbered mounting plates 6 are all connected to the positive port of the multi-channel withstand voltage tester 3 through wires, and before testing, the multi-channel withstand voltage tester 3 needs to be debugged in advance according to the specification of the capacitor body 12, so that the test voltage generated by the multi-channel withstand voltage tester 3 is 1.2 to 1.5 times the rated voltage of the capacitor body 12 to prevent excessive test voltage from damaging the capacitor body 12.

[0022] When testing the capacitor body 12, first control the telescopic parts of all the electric push rods 111 to jointly drive the frame-shaped push plate 112 to move upward, so that the frame-shaped push plate 112 pushes all the mounting plates 6 to slide upward on the corresponding connecting rods 5, and compresses the spring member 7, so that all the mounting plates 6 move upward with the corresponding alligator clips 8 and the parts connected thereto. At the same time, the alligator clips 8 push the L-shaped push plate 10 upward through the corresponding short rods 11 until the conductive clamping plate 9 is moved upward by the corresponding short rods 11. Figure 3 The state shown moves to Figure 7 The designated position shown means that the conductive clamping plate 9 is moved to a position where it can subsequently clamp the metal pin 13 to complete the preparation work before the capacitor body 12 is inspected.

[0023] After completing the preparation work before testing the capacitor body 12, first manually place a capacitor body 12 on each disc 4 in turn. The specific steps for placing a single capacitor body 12 are as follows: manually push the two short rods 11 downward through the L-shaped push plate 10, so that the short rods 11 push the two clamping arms of the two crocodile clips 8 to open, so that the two crocodile clips 8 drive the corresponding two conductive clamping plates 9 away from each other, so that the gap between the two conductive clamping plates 9 set on the mounting plate 16 can be inserted into the metal pin 13. At this time, the torsion spring of the crocodile clip 8 is in a compressed state, and then, the capacitor body 12 is manually placed as shown in the figure. Figure 7 The state shown is placed on the disc 4. At this time, the positive and negative metal pins 13 of the capacitor body 12 will be inserted into the corresponding circular holes 401 respectively and be located between the corresponding two conductive clamps 9, that is, the positive metal pin 13 is connected to the conductive clamp 9 set on the odd-numbered mounting plate 6, and the negative metal pin 13 is connected to the conductive clamp 9 set on the even-numbered mounting plate 6. Then, the L-shaped push plate 10 is manually loosened. At this time, the torsion springs on the two crocodile clips 8 will drive the two clamping arms thereon to close, so that the two crocodile clips 8 drive the corresponding two conductive clamps 9 to approach each other and clamp the corresponding metal pins 13. At this time, the positive and negative ports of the multi-channel withstand voltage tester 3 will be electrically connected to the positive and negative ports of the capacitor body 12 through the corresponding conductive clamps 9 and the corresponding metal pins 13 in turn.

[0024] After a capacitor body 12 is placed on each disk 4 , the multi-channel withstand voltage tester 3 is started to simultaneously detect parameters such as capacitance values, equivalent series resistance, leakage current, etc. of all capacitor bodies 12 .

[0025] It should be noted that before the multi-channel withstand voltage tester 3 simultaneously detects all capacitor bodies 12, the telescopic part of the electric push rod 111 is first controlled to drive the frame-shaped push plate 112 to reset downward, even if the frame-shaped push plate 112 is separated from all mounting plates 6. The following description is based on the leftmost connecting rod 5, mounting plate 6, spring member 7, crocodile clip 8 and conductive clamping plate 9. Since the crocodile clip 8 installed on the leftmost mounting plate 6 sequentially clamps the metal pin 13 on the corresponding capacitor body 12 through the conductive clamping plate 9, and the capacitor body 12 is restricted by the disc 4 and cannot move downward, that is, the mounting plate 6 will be fixedly connected to the metal pin 13 on the capacitor body 12 through the conductive clamping plate 9 in turn, then when the frame-shaped push plate 112 is separated from all mounting plates 6, the mounting plate 6 will not slide downward on the connecting rod 5, so that the spring member 7 remains in a compressed state. At the same time, the spring member 7 in a compressed state will sequentially apply a downward force to the metal pin 13 on the capacitor body 12 through the mounting plate 6, the crocodile clip 8 and the conductive clamping plate 9. force. At this time, if the welding between the metal pin 13 and the capacitor body 12 is not firm, the metal pin 13 will be pulled out of the capacitor body 12 under the action of the tension applied by the spring member 7 in a compressed state. After the metal pin 13 is pulled out of the capacitor body 12, the spring member 7 in a compressed state will push the mounting plate 16, the crocodile clip 8, the conductive clamping plate 9 and the metal pin 13 to move downward, so that the metal pin 13 is away from the capacitor body 12. On the contrary, if the welding between the metal pin 13 and the capacitor body 12 is firm, the metal pin 13 will not be pulled out of the capacitor body 12 under the action of the tension applied by the spring member 7 in a compressed state, so as to detect whether the welding between the metal pin 13 and the capacitor body 12 is firm. At the same time, the connecting rod 5, the mounting plate 16, the spring member 7, the crocodile clip 8 and the conductive clamping plate 9 on the remaining disc 4 will cooperate in the same way as above to detect whether the welding between the corresponding metal pin 13 and the capacitor body 12 is firm.

[0026] When the multi-channel voltage withstand tester 3 detects all the capacitor bodies 12 at the same time, the multi-channel voltage withstand tester 3 will not be able to detect the capacitor body 12 that has lost the metal pin 13 because the connection between the capacitor body 12 that has lost the metal pin 13 and the multi-channel voltage withstand tester 3 cannot form a closed loop. This avoids the problem of artificially treating the capacitor body 12 with the metal pin 13 not being firmly welded as a qualified product because the capacitance value, equivalent series resistance, leakage current and other parameters of the capacitor body 12 with the metal pin 13 not being firmly welded detected by the multi-channel voltage withstand tester 3 are within the standard range compared with the parameters of the qualified capacitor body 12.

[0027] When the multi-channel withstand voltage tester 3 has completed the detection of all capacitor bodies 12, the multi-channel withstand voltage tester 3 is turned off, and then the telescopic parts of all the electric push rods 111 are controlled to jointly drive the frame-shaped push plate 112 to move upward, so that the frame-shaped push plate 112 contacts all the mounting plates 6, and then the capacitor body 12 placed on each disc 4 is manually removed. The specific steps for removing a single capacitor body 12 are as follows: first, a person manually pushes the corresponding two short rods 11 downward through the L-shaped push plate 10 with one hand, so that the short rods 11 push the two clamping arms of the two crocodile clips 8 to open, so that the two crocodile clips 8 drive the corresponding two conductive clamping plates 9 to release the clamping of the metal pin 13, and then the capacitor body 12 that has been tested is removed with the other hand.

[0028] After all the capacitor bodies 12 placed on the discs 4 are removed, the door 101 is manually flipped upward by the handle 102 to open the machine room at the lower side of the rack 1, and then the unplugged metal pins 13 are manually taken out from the machine room at the lower side of the rack 1, and then the door 101 is manually flipped downward by the handle 102 to close the machine room at the lower side of the rack 1. Example 2

[0029] On the basis of Example 1, Figure 1-Figure 6 As shown, a temperature detector 121 and a cutting assembly are also included; each disk 4 is provided with a temperature detector 121; and each disk 4 is connected to a cutting assembly.

[0030] The cutting assembly includes a base plate 211, a long rod 212, a blocking plate 213, an electric push rod 214 and a cutting knife 215; the disc 4 is fixedly connected to the base plate 211; the base plate 211 is slidably connected to two long rods 212; the two long rods 212 are slidably connected to two blocking plates 213 distributed on the left and right; the base plate 211 is bolted to four electric push rods 214 distributed in a rectangular shape, and the telescopic part of each electric push rod 214 is fixedly connected to the corresponding blocking plate 213; each blocking plate 213 is fixedly connected to a cutting knife 215.

[0031] It also includes a cooling component; the frame 1 is connected to four cooling components; the cooling component consists of an electric push rod 3 221, a mounting ring 222, a cylindrical cover 223 and a delivery pipe 224; the frame 1 is bolted to two electric push rods 3 221, and the telescopic parts of all the electric push rods 3 221 are fixedly connected to the mounting ring 222; the mounting ring 222 is connected to the cylindrical cover 223; each disc 4 is fixedly connected to a delivery pipe 224, and all the delivery pipes 224 are connected to an external device for transporting non-conductive coolant.

[0032] Each disc 4 is provided with a circular groove 402 , and the diameter of the circular groove 402 is the same as the diameter of the cylindrical cover 223 ; each circular groove 402 is provided with a sealing ring, which is used to prevent the non-conductive coolant from overflowing from between the disc 4 and the cylindrical cover 223 .

[0033] The cylindrical cover 223 is made of explosion-proof material, such as alloy, etc. Buffer cotton is arranged inside the cylindrical cover 223 .

[0034] In Example 1, it is taken into account that during the process of the multi-channel voltage withstand tester 3 simultaneously testing all the capacitor bodies 12, the internal insulating material of the capacitor body 12 may be broken down due to quality problems. When the internal insulating material of the capacitor body 12 is broken down, if the multi-channel voltage withstand tester 3 continues to test the capacitor body 12, a short-circuit path will be formed inside the capacitor body 12. The short-circuit path will cause the current of the capacitor body 12 to increase sharply and generate a large amount of heat. The temperature of the capacitor body 12 will rise rapidly. As the temperature of the capacitor body 12 continues to rise, the current of the capacitor body 12 will be further increased, forming a vicious circle, which will eventually cause the capacitor body 12 to easily explode due to overheating.

[0035] In order to avoid the explosion of the insulating material inside the capacitor body 12 after being punctured, the capacitor body 12 is usually disconnected from the multi-channel withstand voltage tester 3 when an abnormality is manually discovered in the capacitor body 12. However, manual operation requires a certain reaction time, that is, the capacitor body 12 is prone to explosion if the connection between the multi-channel withstand voltage tester 3 is not disconnected in time, and there is a danger in manually disconnecting the capacitor body 12 from the multi-channel withstand voltage tester 3.

[0036] Therefore, in the process of the multi-channel voltage withstand tester 3 simultaneously testing all the capacitor bodies 12, the temperature condition of the corresponding capacitor body 12 is detected by the temperature detector 121. When the temperature detector 121 detects that the temperature of the corresponding capacitor body 12 rises rapidly, the temperature detector 121 transmits the detected data to the controller 2. After the controller 2 receives the data, the controller 2 controls the cutting component to cut off the metal pins 13 on the capacitor body 12 whose temperature rises rapidly, so as to prevent the multi-channel voltage withstand tester 3 from continuing to test the capacitor body 12 whose temperature rises rapidly.

[0037] The following is the specific operation of the cutting assembly to cut off the metal pins 13 on the capacitor body 12 whose temperature is rapidly increased: first, the four electric push rods 214 located on the substrate 211 below the capacitor body 12 whose temperature is rapidly increased are controlled to work, so that the telescopic parts of the two electric push rods 214 drive the corresponding blocking plates 213 and the parts connected thereto to move toward the substrate 211. In this process, when the two cutting knives 215 pass through the corresponding metal pins 13 on the capacitor body 12 whose temperature is rapidly increased, the two metal pins 13 on the capacitor body 12 will be cut off by the corresponding cutting knives 215. In the process of the cutting knives 215 cutting off the metal pins 13, it can be known from the description of Example 1 that the spring member 7 in a compressed state will apply a downward pulling force to the metal pins 13 on the capacitor body 12, that is, the metal pins 13 on the capacitor body 12 are pulled downward. The metal pin 13 will be in a taut state, so that the cutting knife 215 can better cut off the metal pin 13. When the metal pin 13 is cut off, the spring member 7 in a compressed state will drive the cut metal pin 13 to move downward through the mounting plate 6, the crocodile clip 8, and the conductive clamping plate 9 in sequence, so that the cut metal pin 13 quickly moves away from the capacitor body 12 whose temperature rises rapidly, so that the connection between the capacitor body 12 whose temperature rises rapidly and the multi-channel withstand voltage tester 3 is quickly disconnected, so as to prevent the multi-channel withstand voltage tester 3 from continuing to detect the capacitor body 12 whose temperature rises rapidly, so as to avoid the problem that the capacitor body 12 is prone to bursting due to overheating if the multi-channel withstand voltage tester 3 continues to detect the capacitor body 12 when the insulating material inside the capacitor body 12 breaks down.

[0038] Considering that after the capacitor body 12 whose temperature rises rapidly is quickly disconnected from the multi-channel withstand voltage tester 3, the energy stored inside the capacitor body 12 will be quickly released through the short-circuit path. This energy is released in the form of Joule heat, continuing to generate heat, causing the internal temperature of the capacitor body 12 to continue to rise. As the internal temperature of the capacitor body 12 continues to rise, the capacitor casing will not be able to withstand such extreme conditions, and will eventually cause the capacitor body 12 to still be prone to explosion due to overheating.

[0039] Therefore, after the cutting knife 215 cuts off the metal pin 13, the telescopic parts of the four electric push rods 214 continue to drive the corresponding blocking plates 213 and the parts connected thereto to move toward the substrate 211 until the two blocking plates 213 block the corresponding circular holes 401. At the same time, the electric push rod 3 221 located above the capacitor body 12 whose temperature rises rapidly is controlled to work, so that the telescopic part of the electric push rod 3 221 pushes the corresponding mounting ring 222 and the parts connected thereto to move downward, so that the cylindrical cover 223 contacts the corresponding disc 4. At this time, the capacitor body 12 whose temperature rises rapidly will be covered by the cylindrical cover 223. Since the two circular holes 401 on the disc 4 are blocked by the corresponding blocking plates 213, the disc 4 and the blocking plates will be blocked. The plate 213 and the cylindrical cover 223 cooperate to form a closed space, and then the external conveying equipment is controlled to convey the non-conductive coolant (such as mineral oil, silicone oil and fluorinated liquid, etc.) into the closed space through the conveying pipe 224, so that the non-conductive coolant absorbs and takes away the heat in the capacitor body 12 whose temperature rises rapidly, so that the heat in the capacitor body 12 whose temperature rises rapidly is in a thermal equilibrium state, preventing the temperature of the capacitor body 12 from continuing to rise, so as to reduce the risk that after the insulating material inside the capacitor body 12 is broken down, the energy stored in the capacitor body 12 will be rapidly released through the short-circuit path, causing the internal temperature of the capacitor body 12 to continue to rise, and eventually causing the capacitor body 12 to still be prone to the risk of bursting due to overheating.

[0040] When the temperature detector 121 detects that the internal heat of the capacitor body 12 with a rapidly rising temperature has been absorbed by the non-conductive coolant, and the internal heat of the capacitor body 12 with a rapidly rising temperature will not continue to rise, the controller 2 controls the external conveying equipment to draw the non-conductive coolant in the enclosed space back into the interior through the conveying pipe 224, and then controls the telescopic part of the electric push rod 3 221 to drive the mounting ring 222 and the parts connected thereto to move upward and restore the initial position, so that the capacitor body 12 with a rapidly rising temperature can be manually removed from the disk 4.

[0041] Furthermore, although the heat in the rapidly heated capacitor body 12 can be absorbed and carried away by the non-conductive coolant, when the heat in the rapidly heated capacitor body 12 is already very high, it is difficult for the non-conductive coolant to quickly bring the heat in the rapidly heated capacitor body 12 into a thermal equilibrium state, and the rapidly heated capacitor body 12 is still prone to the risk of bursting. The energy and fragments generated when the rapidly heated capacitor body 12 bursts propagate outward, threatening the safety of surrounding humans.

[0042] Therefore, by setting the cylindrical cover 223 to an explosion-proof material and arranging buffer cotton on the inner side of the cylindrical cover 223, the cylindrical cover 223 can block the energy and fragments generated when the temperature rises rapidly and the capacitor body 12 explodes from propagating outward, so as to protect human safety and prevent the energy and fragments generated when the temperature rises rapidly and the capacitor body 12 explodes from propagating outward, causing the problem that the safety of surrounding humans will be threatened. Example 3

[0043] On the basis of Example 2, Figure 3 and Figure 4 As shown, it also includes an observation component; the frame 1 is connected to the observation component, and the observation component is connected to all the disks 4; the observation component consists of an electric slider 411, a mounting plate 412, a camera 413 and a power unit; the frame 1 is slidably connected to the electric slider 411; the electric slider 411 is bolted to the mounting plate 412; the mounting plate 412 is bolted to the camera 413 for photographing the surface condition of the capacitor body 12; the frame 1 is connected to the power unit, and the power unit is connected to all the disks 4.

[0044] The power unit includes an electric slider 2 421, a long plate 422, a rack 423 and a gear ring 424; the frame 1 is slidably connected to the two electric sliders 2 421; the two electric sliders 2 421 are bolted together with the long plate 422; the long plate 422 is fixedly connected with the rack 423; each disc 4 is fixedly connected with a gear ring 424, the rack 423 is meshed with the gear ring 424, and the gear ring 424 cooperates with the rack 423 to drive the disc 4 and the parts connected thereto to rotate.

[0045] The specific work of the above-mentioned embodiment 4 is as follows: Considering that after the capacitor body 12 is inspected, the side of the unqualified capacitor body 12 may have signs of burning, electrolyte leakage, cracks, stains or cracks, etc., it is easy to detect leaks by manually observing whether each capacitor body 12 has the above-mentioned conditions.

[0046] Therefore, after the capacitor body 12 is detected, the electric slider 1 411 is first controlled to drive the camera 413 to move to the right through the mounting plate 2 412, so that the camera 413 is at the rear side of the leftmost disc 4, and then the electric slider 2 421 is controlled to drive the rack 423 to move to the right through the long plate 422, until the rack 423 passes through the leftmost gear ring 424. When the rack 423 passes through the leftmost gear ring 424, the rack 423 drives the leftmost disc 4 and its connected parts to rotate one circle through the leftmost gear ring 424, so that the capacitor body 12 on the leftmost disc 4 rotates one circle. In this process, The condition of the side surface of the capacitor body 12 on the leftmost circular disk 4 is photographed by the camera 413, and the photographed condition is transmitted to the controller 2, so that the controller 2 analyzes whether there are any signs of burnt marks, electrolyte leakage, cracks, contamination or cracks on the side surface of the capacitor body 12 on the leftmost circular disk 4 according to the condition of the side surface of the capacitor body 12 on the leftmost circular disk 4 photographed by the camera 413, and displays the analyzed condition on its display screen, so that a human can intuitively know whether there are any signs of burnt marks, electrolyte leakage, cracks, contamination or cracks on the side surface of the capacitor body 12 on the leftmost circular disk 4.

[0047] Then, the above steps are repeated until the camera 413 completes photographing the side surfaces of the capacitor bodies 12 on all the disks 4 .

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
