Detailed implementation manners
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited. Embodiment 1
[0028] A multi-angle detection device for the production of electrolytic capacitors, as shown in Figures 1-5 and Figure 7As shown in the figure, it includes a machine frame 1, a controller 2 and a multi-channel withstand voltage tester 3; a door 101 is hinged to the machine frame 1; a handle 102 is bolted to the door 101; a controller 2 for controlling all the electric drive parts of this equipment is bolted to the machine frame 1; a multi-channel withstand voltage tester 3 for performing a withstand voltage test on the capacitor body 12 is bolted to the machine frame 1;
[0029] It also includes a disc 4, a connecting rod 5, a first mounting plate 6, a spring member 7, an alligator clip 8, a conductive clamping plate 9, an L-shaped push plate 10, a short rod 11 and a pushing assembly; four discs 4 for placing the capacitor body 12 are rotatably connected to the machine frame 1; two circular holes 401 distributed left and right are provided in each disc 4; four connecting rods 5 distributed in a rectangle are fixedly connected to each disc 4; two connecting rods 5 symmetrically distributed front and back on each disc 4 are commonly connected to a first mounting plate 6; a spring member 7 is sleeved on each connecting rod 5, and each spring member 7 is fixedly connected to the corresponding disc 4 and the first mounting plate 6; an alligator clip 8 is fixedly connected to each first mounting plate 6; a conductive clamping plate 9 is fixedly connected to each of the two clamping arms of each alligator clip 8, and the multi-channel withstand voltage tester 3 is electrically connected to the conductive clamping plate 9 through an electric wire; an L-shaped push plate 10 is slidably connected to each disc 4; two short rods 11 are fixedly connected to each L-shaped push plate 10, and each short rod 11 contacts the clamping arm of the corresponding alligator clip 8; the machine frame 1 is connected with a pushing assembly.
[0030] The pushing assembly includes a first electric push rod 111 and a frame-shaped push plate 112; four first electric push rods 111 distributed in a rectangle are bolted to the machine frame 1; the telescopic parts of all the first electric push rods 111 are commonly fixedly connected to a frame-shaped push plate 112 for pushing the first mounting plate 6 and the parts connected thereto to move, and the frame-shaped push plate 112 contacts all the first mounting plates 6.
[0031] The circular hole 401 is arranged in a frustum shape, and this arrangement is used to make the metal pin 13 better inserted into the circular hole 401.
[0032] The specific working process is as follows: It should be noted in advance that all the electric drive parts of this equipment are controlled by the controller 2. The following descriptions are all based on Figure 1 the perspective reference, Figure 1 with the side where the label of the controller 2 is located as the front and the side where the label of the machine frame 1 is located as the left when looking from left to right. The conductive clamping plates 9 arranged on the odd-numbered first mounting plates 6 are all connected to the negative terminal port of the multi-channel withstand voltage tester 3 through electric wires, and the conductive clamping plates 9 arranged on the even-numbered first mounting plates 6 are all connected to the positive terminal port of the multi-channel withstand voltage tester 3 through electric wires. And before the test, 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 the capacitor body 12 from being damaged due to too high a test voltage.
[0033] 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 support the corresponding crocodile clips 8 and the parts connected thereto to move upward. At the same time, the crocodile clips 8 will push the L-shaped push plate 10 upward through the corresponding short rods 11 until the conductive clamping plate 9 is as shown. Figure 3 The state shown moves to Figure 7 The designated position shown means that the conductive clamp 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 tested.
[0034] After completing the preparations 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 clamps 9 away from each other, so that the gap between the two conductive clamps 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. Then, manually place the capacitor body 12 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 released. 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 voltage withstand 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 sequence.
[0035] After a capacitor body 12 is placed on each disk 4 , the multi-channel voltage tester 3 is started to simultaneously test parameters such as capacitance, equivalent series resistance, and leakage current of all capacitor bodies 12 .
[0036] It should be noted that before the multi-channel withstand voltage tester 3 detects all the capacitor bodies 12 at the same time, first control the telescopic part of the electric push rod 111 to drive the frame-shaped push plate 112 to reset downward, that is, to separate the frame-shaped push plate 112 from all the first mounting plates 6. The following description is based on the leftmost connecting rod 5, the first mounting plate 6, the spring member 7, the alligator clip 8 and the conductive clamping plate 9. Since the alligator clip 8 mounted on the leftmost first mounting plate 6 sequentially clamps the metal pins 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 first mounting plate 6 will be fixedly connected to the metal pins 13 on the capacitor body 12 through the conductive clamping plate 9 in sequence. When the frame-shaped push plate 112 separates from all the first mounting plates 6, the first 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 compressed spring member 7 will apply a downward force to the metal pins 13 on the capacitor body 12 through the first mounting plate 6, the alligator clip 8 and the conductive clamping plate 9 in sequence. 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 from the capacitor body 12 under the action of the pulling force applied by the compressed spring member 7. After the metal pin 13 is pulled out from the capacitor body 12, the compressed spring member 7 will push the first mounting plate 6, the alligator clip 8, the conductive clamping plate 9 and the metal pin 13 downward to move the metal pin 13 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 from the capacitor body 12 under the action of the pulling force applied by the compressed spring member 7, 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 first mounting plate 6, the spring member 7, the alligator clip 8 and the conductive clamping plate 9 on the remaining discs 4 will cooperate to detect whether the welding between the corresponding metal pins 13 and the capacitor bodies 12 is firm in the same way as above.
[0037] When the multi-channel withstand voltage tester 3 detects all the capacitor bodies 12 at the same time, since the connection between the capacitor body 12 without the metal pin 13 and the multi-channel withstand voltage tester 3 cannot form a closed loop, the multi-channel withstand voltage tester 3 will not be able to detect the capacitor body 12 without the metal pin 13, so as to avoid the problem that when the welding between the metal pin 13 and the capacitor body 12 is not firm, the capacitance value, equivalent series resistance, leakage current and other parameters of the capacitor body 12 with the metal pin 13 welded not firmly detected by the multi-channel withstand voltage tester 3 deviate within the standard range from those of the qualified capacitor body 12, resulting in the situation that the capacitor body 12 with the metal pin 13 welded not firmly is regarded as a qualified product manually.
[0038] When the multi-channel withstand voltage tester 3 finishes detecting all the capacitor bodies 12, turn off the multi-channel withstand voltage tester 3, and then control the telescopic parts of all the electric push rods 111 to drive the frame-shaped push plate 112 to move upward together, so that the frame-shaped push plate 112 contacts all the first mounting plates 6. Then, manually remove the capacitor bodies 12 placed on each disc 4. The specific steps for removing a single capacitor body 12 are as follows: First, manually use one hand to push the corresponding 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 alligator clips 8 to open, so that the two alligator clips 8 drive the corresponding two conductive clamping plates 9 to release the clamping of the metal pins 13. Then, use the other hand to remove the detected capacitor body 12.
[0039] After all the capacitor bodies 12 placed on all the discs 4 are removed, manually drive the door 101 to flip upward through the handle 102 to open the machine chamber on the lower side of the frame 1. Then, manually take out the unplugged metal pins 13 from the machine chamber on the lower side of the frame 1. Then, drive the door 101 to flip downward through the handle 102 to close the machine chamber on the lower side of the frame 1. Embodiment 2
[0040] Based on Embodiment 1, as Figures 1-6 shown, it further includes a temperature detector 121 and a cutting assembly; each disc 4 is provided with a temperature detector 121; each disc 4 is connected with a cutting assembly.
[0041] The cutting assembly includes a substrate 211, a long rod 212, a sealing plate 213, an electric push rod 214 and a cutting knife 215; the disc 4 is fixedly connected with the substrate 211; two long rods 212 are slidably connected to the substrate 211; two sealing plates 213 distributed left and right are slidably connected to the two long rods 212 together; four electric push rods 214 distributed in a rectangle are bolted to the substrate 211, and the telescopic part of each electric push rod 214 is fixedly connected with the corresponding sealing plate 213; each sealing plate 213 is fixedly connected with a cutting knife 215.
[0042] It further includes a cooling assembly; four cooling assemblies are connected to the frame 1; the cooling assembly is composed of an electric push rod 221, a mounting ring 222, a cylindrical cover 223 and a delivery pipe 224; two electric push rods 221 are bolted to the frame 1, and the telescopic parts of all the electric push rods 221 are fixedly connected with the mounting ring 222 together; the mounting ring 222 is connected with the cylindrical cover 223; each disc 4 is fixedly connected with a delivery pipe 224, and all the delivery pipes 224 are connected with the equipment for delivering non-conductive coolant outside.
[0043] Each disc 4 is provided with a circular groove 402, and the diameter of the circular groove 402 is the same as that of the cylindrical cover 223; a sealing ring is provided in each circular groove 402, and the sealing ring is used to prevent the non-conductive coolant from overflowing between the disc 4 and the cylindrical cover 223.
[0044] The cylindrical cover 223 is made of explosion-proof material, such as alloy, etc.; buffer cotton is provided on the inner side of the cylindrical cover 223.
[0045] In Embodiment 1, considering that during the process of the multi-channel withstand voltage tester 3 detecting all the capacitor bodies 12 simultaneously, 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 breaks down, if the multi-channel withstand voltage tester 3 continues to detect the capacitor body 12, since 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, and 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 further increase, forming a vicious cycle, and finally the capacitor body 12 is likely to explode due to overheating.
[0046] Currently, to avoid the explosion of the capacitor body 12 after the internal insulating material is broken down, usually when it is manually found that the capacitor body 12 is abnormal, the connection between the capacitor body 12 and the multi-channel withstand voltage tester 3 will be disconnected. However, manual operation requires a certain reaction time, that is, the connection between the capacitor body 12 and the multi-channel withstand voltage tester 3 is not disconnected in time and it is easy to have an explosion phenomenon, and the method of manually disconnecting the connection between the capacitor body 12 and the multi-channel withstand voltage tester 3 is dangerous.
[0047] Therefore, during the process of the multi-channel withstand voltage tester 3 detecting all the capacitor bodies 12 simultaneously, the temperature detector 121 detects the temperature of the corresponding capacitor body 12. When the temperature detector 121 detects that the temperature of the corresponding capacitor body 12 rises rapidly, the temperature detector 121 will transmit the detected data to the controller 2. After receiving the data, the controller 2 will control the cutting component to cut off the metal pin 13 on the capacitor body 12 with a rapidly rising temperature, so as to prevent the multi-channel withstand voltage tester 3 from continuing to detect the capacitor body 12 with a rapidly rising temperature.
[0048] The following is the specific operation of the cutting component to quickly raise the temperature and cut the metal pins 13 on the capacitor body 12: First, control the four electric push rods two 214 on the substrate 211 below the capacitor body 12 with rapidly rising temperature to work, so that the telescopic parts of the two electric push rods two 214 drive the corresponding sealing plates 213 and the parts connected thereto to move towards the substrate 211. During this process, when the two cutting blades 215 pass through the corresponding metal pins 13 on the capacitor body 12 with rapidly rising temperature, the two metal pins 13 on the capacitor body 12 will be cut off by the corresponding cutting blades 215. During the process of the cutting blade 215 cutting off the metal pin 13, as can be seen from Embodiment 1, the spring member 7 in the compressed state will apply a downward pulling force on the metal pin 13 on the capacitor body 12, that is, the metal pin 13 on the capacitor body 12 will be in a taut state, so that the cutting blade 215 can better cut off the metal pin 13. When the metal pin 13 is cut off, the spring member 7 in the compressed state will drive the cut-off metal pin 13 to move downward through the first mounting plate 6, the alligator clip 8, and the conductive clamping plate 9 in sequence, so that the cut-off metal pin 13 quickly moves away from the capacitor body 12 with rapidly rising temperature, so that the connection between the capacitor body 12 with rapidly rising temperature and the multi-channel withstand voltage tester 3 is quickly disconnected, preventing the multi-channel withstand voltage tester 3 from continuing to detect the capacitor body 12 with rapidly rising temperature, so as to avoid the problem that when the insulating material inside the capacitor body 12 breaks down, if the multi-channel withstand voltage tester 3 continues to detect this capacitor body 12, the capacitor body 12 is likely to explode due to overheating.
[0049] Considering that after the connection between the capacitor body 12 with rapidly rising temperature and the multi-channel withstand voltage tester 3 is quickly disconnected, since the energy stored inside the capacitor body 12 will be quickly released through the short-circuit path, and these energies are 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 outer shell of the capacitor will not be able to withstand this extreme condition, and finally the capacitor body 12 is still likely to explode due to overheating.
[0050] Therefore, after the cutting blade 215 cuts off the metal pins 13, the telescopic parts of the four electric push rods II 214 continue to drive the corresponding sealing plates 213 and the parts connected thereto to move towards the substrate 211 until the two sealing plates 213 block the corresponding round holes 401. At the same time, control the electric push rod III 221 located above the capacitor body 12 with rapidly increasing temperature to work, so that the telescopic part of the electric push rod III 221 pushes the corresponding mounting ring 222 and the parts connected thereto to move downward, making the cylindrical cover 223 contact the corresponding disc 4. At this time, the capacitor body 12 with rapidly increasing temperature will be covered by the cylindrical cover 223. Since the two round holes 401 on the disc 4 are blocked by the corresponding sealing plates 213, the disc 4, the sealing plates 213 and the cylindrical cover 223 cooperate to form a sealed space. Then control the external conveying device to convey non-conductive coolant (such as mineral oil, silicone oil, fluorinated liquid, etc.) into the sealed space through the conveying pipe 224, so that the non-conductive coolant absorbs and takes away the heat in the capacitor body 12 with rapidly increasing temperature, so that the heat in the capacitor body 12 with rapidly increasing temperature is in a heat balance state, preventing the temperature of the capacitor body 12 from continuing to rise, so as to reduce the risk that after the internal insulating material of the capacitor body 12 is broken down, the energy stored in the capacitor body 12 will be quickly released through a short-circuit path, resulting in the continuous rise of the internal temperature of the capacitor body 12, and ultimately leading to the risk that the capacitor body 12 is still prone to explosion due to overheating.
[0051] When the temperature detector 121 detects that the heat inside the capacitor body 12 with rapidly increasing temperature has been absorbed by the non-conductive coolant and the internal heat of the capacitor body 12 with rapidly increasing temperature will not continue to rise, the controller 2 controls the external conveying device to pump the non-conductive coolant in the sealed space back into its interior through the conveying pipe 224, and then controls the telescopic part of the electric push rod III 221 to drive the mounting ring 222 and the parts connected thereto to move upward to restore the initial position, so that the operator can take away the capacitor body 12 with rapidly increasing temperature from the disc 4.
[0052] Furthermore, considering that although the non-conductive coolant can absorb and take away the heat in the capacitor body 12 with rapidly increasing temperature, when the heat in the capacitor body 12 with rapidly increasing temperature is already very high, it is difficult for the non-conductive coolant to quickly bring the heat in the capacitor body 12 with rapidly increasing temperature into a heat balance state, so the capacitor body 12 with rapidly increasing temperature is still prone to the risk of explosion. When the capacitor body 12 with rapidly increasing temperature explodes, the energy and fragments generated spread outward, threatening the safety of the surrounding personnel.
[0053] Therefore, by setting the cylindrical cover 223 to be made of explosion-proof material and providing buffer cotton inside the cylindrical cover 223, the cylindrical cover 223 can block the energy and debris generated when the capacitor body 12 explodes due to a rapid temperature increase from spreading outward, protecting the safety of personnel and preventing the energy and debris generated when the capacitor body 12 explodes due to a rapid temperature increase from spreading outward, which may pose a threat to the safety of surrounding personnel. Embodiment 3
[0054] Based on Embodiment 2, as Figure 3 and Figure 4 shown, it further includes an observation component; the frame 1 is connected to the observation component, and the observation component is connected to all the discs 4; the observation component is composed 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 discs 4.
[0055] The power unit includes an electric slider 421, a long plate 422, a rack 423 and a toothed ring 424; two electric sliders 421 are slidably connected to the frame 1; the two electric sliders 421 are jointly bolted to the long plate 422; the long plate 422 is fixedly connected to the rack 423; each disc 4 is fixedly connected to a toothed ring 424, and the rack 423 meshes with the toothed ring 424. The cooperation between the toothed ring 424 and the rack 423 is used to drive the disc 4 and its connected parts to rotate.
[0056] The specific operation of the above Embodiment 4 is as follows: Considering that after the capacitor body 12 is detected, there may be situations such as charred marks, electrolyte leakage, cracks, dirt or cracks on the side of the unqualified capacitor body 12. It is easy to miss inspections when manually observing whether each capacitor body 12 has the above situations.
[0057] Therefore, after the detection of the capacitor body 12 is completed, first control the electric slider 411 to drive the camera 413 to move to the right through the second mounting plate 412, so that the camera 413 is located behind the leftmost disk 4. Then control the electric slider 421 to drive the rack 423 to move to the right through the long plate 422 until the rack 423 passes through the leftmost toothed ring 424. When the rack 423 passes through the leftmost toothed ring 424, the rack 423 will drive the leftmost disk 4 and its connected parts to rotate one circle through the leftmost toothed ring 424, so that the capacitor body 12 on the leftmost disk 4 rotates one circle. During this process, the camera 413 takes pictures of the side of the capacitor body 12 on the leftmost disk 4 and transmits the taken pictures to the controller 2, so that the controller 2 analyzes whether there are burnt marks, electrolyte leakage, cracks, dirt or cracks on the side of the capacitor body 12 on the leftmost disk 4 according to the pictures taken by the camera 413, and displays the analyzed situation through its display screen, so that the operator can intuitively know whether there are burnt marks, electrolyte leakage, cracks, dirt or cracks on the side of the capacitor body 12 on the leftmost disk 4.
[0058] Then repeat the above working steps until the camera 413 has taken pictures of the sides of all the capacitor bodies 12 on the disks 4.

Those skilled in 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 by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
