DETAILED DESCRIPTION
[0076] The application will be further described in detail below with reference to the drawings and examples.
[0077] The application discloses a capacitor.
[0078] Referring to Figure 1 and Figure 2 A capacitor comprises a capacitor body 1, a plurality of polishing structures 2, a plurality of clamping structures 3, a bottom plate 4, a shell 5, a supporting plate 6, a pressing plate 7 and a detection plate 8.
[0079] The capacitor body 1 is fixedly connected with a plurality of pins 11 at the lower part, and the pins 11 are provided with clamping grooves 12.
[0080] The bottom plate 4 is provided with a plurality of connecting terminals 41 corresponding to the pins 11, for connecting with an external zero line or live wire.
[0081] Referring to Figure 3 and Figure 4 The plurality of polishing structures 2 are provided in one-to-one correspondence with the pins 11, and the polishing structure 2 comprises a mounting seat 21, a pressure plate 22, a first spring 23, a driving mechanism 24, a threaded cylinder 25 and sandpaper 26.
[0082] The mounting seat 21 is fixedly mounted on the bottom plate 4 and is provided with a mounting groove 212 on the inner side for inserting the pin 11, and the mounting groove 212 is provided with a sliding groove 213 on both sides for limiting the pressure plate 22, and the mounting seat 21 is threadedly connected with a dismounting cover 211 at the upper part.
[0083] The pressure plate 22 is located inside the installation groove 212 and slides up and down along the mounting base 21. A communication port 221 is formed on the pressure plate 22 to communicate the lower side and the upper side of the pressure plate 22 so as to facilitate the passage of the conductive liquid pre-set inside the installation groove 212. A flow-through groove 222 is formed on the upper side of the pressure plate 22 and communicates with the communication port 221. The flow-through groove 222 is composed of an inner ring groove and an outer ring groove, and a gap is formed between the inner ring groove and the outer ring groove for communication. The flow-through groove 222 is used to pass the conductive liquid when the pin 11 abuts against the pressure plate 22.
[0084] The first spring 23 is located inside the installation groove 212 and is fixedly connected to the mounting base 21 and the pressure plate 22 at both ends, respectively. The first spring 23 always has a tendency to drive the pressure plate 22 away from the installation groove 212.
[0085] The driving mechanism 24 is composed of a driving rod 241 symmetrically arranged on the pressure plate 22 and a protrusion 242 located at the end of the driving rod 241. The driving rod 241 is limited to slide in the sliding groove 213.
[0086] The threaded cylinder 25 is located inside the installation groove 212 and is rotationally connected to the dismounting cover 211. A threaded groove is formed on the outer side of the threaded cylinder 25 and is slidably connected to the protrusion 242.
[0087] The sandpaper 26 is fixedly installed inside the threaded cylinder 25 and is used to polish the pin 11.
[0088] In use, the conductive liquid is injected into the installation groove 212, and then the pin 11 of the capacitor body 1 is inserted into the installation groove 212 correspondingly. The pin 11 drives the pressure plate 22 to compress the first spring 23. The pressure plate 22 drives the driving rod 241 to move downward along the sliding groove 213. The driving rod 241 drives the protrusion 242 to move along the threaded groove on the outer side of the threaded cylinder 25 to drive the threaded cylinder 25 to rotate along the dismounting cover 211. The threaded cylinder 25 drives the sandpaper 26 to rotate to polish the outer side of the pin 11 to eliminate the oxidation layer, thereby avoiding the increase of the resistance of the pin 11 to affect the normal use of the capacitor. At the same time, the downward movement of the pressure plate 22 extrudes the conductive liquid to move to the outer side of the pin 11 through the communication port 221 and the flow-through groove 222, thereby further improving the conductivity between the pin 11 and the clamping rod 31.
[0089] The clamping structure 3 includes a clamping rod 31, a mounting plate 32, a second spring 33, a limiting plate 34, and a third spring 35.
[0090] Referring to Figure 3 and Figure 5The clamping rod 31 is slidably installed on the mounting plate 32 and penetrates one side of the mounting base 21 at one end, the clamping rod 31 is inserted into the clamping groove 12 and clamped with the pin 11 at one end, and the clamping rod 31 is in abutment with the outer side of the pin 11 to achieve electrical connection. A plurality of clamping rods 31 are electrically connected with one connecting terminal 41 respectively, so that when the pin 11 of the capacitor body 1 is connected with the clamping rod 31, the capacitor body 1 is electrically connected with the live wire and the zero line through the connecting terminal 41. The clamping rod 31 is integrally provided with a boss 311, and the upper side of the boss 311 is provided as an inclined surface.
[0091] The mounting plate 32 is fixedly installed on the bottom plate 4. The second spring 33 is sleeved outside the clamping rod 31 and fixedly connected with the boss 311 and the mounting plate 32 at both ends respectively, and the second spring 33 always has a tendency to push the clamping rod 31 close to the clamping groove 12.
[0092] The limiting plate 34 is slidably connected with the clamping rod 31, the limiting plate 34 is provided with a penetrating groove 342 for the clamping rod 31 to pass through and slide up and down, and the limiting plate 34 is also provided with an accommodating groove 341 for accommodating the boss 311 when the clamping rod 31 is inserted into the clamping groove 12. The accommodating groove 341 is provided as an inclined surface in abutment with the upper side of the boss 311, for pushing the boss 311 to move away from the direction of the clamping groove 12 when the limiting plate 34 moves downward to achieve unlocking of the pin 11 to the clamping rod 31.
[0093] The third spring 35 is fixedly installed between the limiting plate 34 and the bottom plate 4 and always has a tendency to push the limiting plate 34 away from the bottom plate 4.
[0094] In use, the capacitor body 1 moves downward to drive the limiting plate 34 to compress the third spring 35, at this time the boss 311 on the clamping rod 31 is in abutment with the limiting plate 34 and slides along the surface of the limiting plate 34 under the action of the second spring 33. When the pin 11 is completely inserted into the mounting groove 212, the accommodating groove 341 on the limiting plate 34 is just moved to the position of the boss 311, the boss 311 is moved into the accommodating groove 341 under the action of the second spring 33, and the clamping rod 31 is inserted into the clamping groove 12 to complete clamping and fixing. Without the need for fixing by bolts or welding, the installation speed is improved and the installation difficulty is reduced.
[0095] Referring to Figures 1 to 5 The shell 5 is fixedly installed on the bottom plate 4 and located outside the plurality of clamping structures 3 for protection. The shell 5 is provided with a through groove for the clamping rod 31 to pass through, an opening for the pressing plate 7 to extend to the outside, and a through hole for cooperation with the detection plate 8. The clamping rod 31 passes through the through groove provided on the shell 5 and is in limiting and sliding connection with the shell 5.
[0096] The supporting plate 6 is fixedly installed above the limiting plate 34 and is in sliding connection with the shell 5.
[0097] The pressing plate 7 is U-shaped and fixedly installed below the supporting plate 6, and one end of the pressing plate 7 extends to the outside through an opening on the shell 5 for manual pressing.
[0098] The detection plate 8 is fixedly installed at the lower end of the pressing plate 7, and a plurality of detection ports 81 are formed on the detection plate 8 and are electrically connected with the clamping rods 31 one by one. The detection ports 81 are exposed through the through holes on the shell 5 when the pins 11 are inserted into the installation grooves 212, so as to facilitate external detection connection.
[0099] In use, when the capacitor body 1 is lowered, the supporting plate 6 supports it, and at the same time, the plurality of limiting plates 34 are simultaneously lowered. When disassembling, the pressing plate 7 is pressed downward, and the supporting plate 6 and the limiting plate 34 are sequentially moved by the pressing plate 7. The convex 311 moves along the inclined surface of the accommodating groove 341 and compresses the second spring 33, so as to drive the clamping rod 31 to slowly separate from the clamping groove 12. When the clamping rod 31 is completely separated from the clamping groove 12, the first spring 23 pushes the stressed plate 22 and the pin 11 to move upward, so as to completely take out the capacitor body 1. The quick disassembly of the capacitor body 1 without the aid of other tools is realized, and the replacement or maintenance of the capacitor body 1 is facilitated. When the capacitor body 1 is installed, the detection plate 8 moves to the through hole of the shell 5 together with the supporting plate 6, and the detection port 81 is exposed for connection of the detection equipment to realize detection, without the need to disassemble the capacitor body 1 or disconnect the connecting terminal 41 for detection, thereby improving the detection convenience. When the capacitor body 1 is disassembled, the detection plate 8 moves upward together with the supporting plate 6 under the action of the third spring 35, so that the detection port 81 is blocked by the shell 5, thereby avoiding accidental damage when not in use.
[0100] Based on the same inventive concept, the embodiment of the present application provides a capacitor control method.
[0101] Reference Figure 6 A capacitor control method comprises the following steps:
[0102] Step 1: responding to trigger information to obtain capacitor model, reference position interval and detection information in detection position.
[0103] The trigger information refers to a trigger signal for starting the capacitor detection and processing process, which can be output by device running instructions or manual operation instructions, and specifically, a worker can click a start button on an operation panel, which is a starting switch of the whole process.
[0104] The capacitor model is a specific number or code for identifying the specifications and parameters of the capacitor, which contains information such as product size, pin 11 quantity and characteristics, and is obtained by scanning a two-dimensional code on the capacitor body 1 and matching from a database. The two-dimensional code is pasted on the capacitor body 1 when the capacitor body 1 is produced and factory.
[0105] The reference position interval refers to the standard position range where the pin 11 should be, which is determined based on the design specifications and production standards of the capacitor model and is pre-recorded in the database by the staff.
[0106] The detection position refers to the specific position where the capacitor body 1 should be when detecting the capacitor body 1, which is pre-set by the staff and then read by the system after being recorded in the database.
[0107] The detection information refers to the signal sent when the detection position is identified to have a capacitor body 1 to be detected, which can be obtained by a pressure sensor to determine the presence of the signal.
[0108] When the system senses the trigger information, it reads the capacitor model and the reference position interval from the database, and also senses the detection information to ensure that the detection position has a capacitor body 1 to be detected, so as to proceed to the subsequent processing steps.
[0109] Step 2: Determine the emission wavelength and detection path of the pin 11 according to the capacitor model.
[0110] The emission wavelength is the wavelength parameter of the light emitted by the laser emitter during detection, which is read from the capacitor model based on the material of the pin 11, and the corresponding wavelength parameter is obtained from the wavelength correspondence table according to the material of the pin 11. The wavelength correspondence table refers to a data table that records different pin materials and their corresponding wavelength parameters, which is pre-recorded by technical personnel through experiments and will not be described here.
[0111] The wavelength of the light reflected after the light shines on the surface of the pin 11 will attenuate, and the attenuation degree affected by pins of different materials is different, so the emission wavelength needs to be matched according to the pin material.
[0112] The detection path is the trajectory of the light during detection, which is pre-planned and set based on the pin shape, distribution and detection range read from the capacitor model.
[0113] Step 3: Emit light to the pin 11 with the emission wavelength and move along the detection path according to the detection information, collect the reflection wavelength during the movement, and then determine the reflection position interval according to the reflection wavelength.
[0114] The reflection wavelength refers to the wavelength of the light reflected back by the surface of the pin 11 after the light shines on the pin 11, which is obtained by the detection device in real time during the movement of the light along the detection path.
[0115] The reflection position interval refers to the position range of the pin 11 actually reflecting the light during detection, which is determined by collecting the reflection wavelength in real time and calculating the corresponding position coordinates.
[0116] After the system senses the detection information, the laser emitter preset on the side of the detection position is controlled to emit light of a wavelength and move along the detection path, and the detection device is controlled to collect the reflected light.
[0117] During the movement of the light, no reflected light is generated when the light is irradiated on the position without the pin 11, and the reflected wavelength cannot be obtained at this time. The reflected light is collected when the light is irradiated on the position with the pin to determine the reflected wavelength and the reflected position interval.
[0118] Step 4: When the reflected position interval is inconsistent with the reference position interval, the position corresponding to the reflected position interval is defined as an abnormal position. The abnormal position is processed by a preset straightening method, and the corrosion type is determined according to the reflected wavelength. The corrosion type includes a first type, a second type, and a third type.
[0119] The inconsistency between the reflected position interval and the reference position interval represents that the pin 11 corresponding to the reference position interval is inclined and thus changes the original position.
[0120] The abnormal position refers to the position of the pin 11 whose reflected position interval is inconsistent with the reference position interval, which is determined by comparing the two.
[0121] The preset straightening method is a standardized operation process for correcting the pin 11 in the abnormal position, which is prepared according to different capacitor models and stored in the system.
[0122] The corrosion type is a category divided according to the corrosion degree of the surface of the pin 11, which includes a first type, a second type, and a third type, which is determined by detecting the reflected wavelength and comparing it with the wavelength interval corresponding to each level.
[0123] In this embodiment, the first type represents that the pin 11 is severely corroded, which is prone to bending and cannot be restored or is prone to falling off, and its metal glossiness is usually lower than 40GU, and the oxidation ratio is higher than 30%; the second type represents that the pin 11 is slightly corroded, and its surface has an oxidation layer that affects normal use, and its metal glossiness is usually between 40GU and 80GU, and the oxidation ratio is between 5% and 30%; the third type represents that the pin 11 almost does not have corrosion and can be directly used, and its metal glossiness is usually between 80GU and 100GU, and the oxidation ratio is lower than 5%.
[0124] The processing method includes a polishing method, which includes the following steps:
[0125] Step 50: Based on the first type, the poking area, the poking rate, and the polishing path are determined according to the capacitor model.
[0126] The poking area is the operating range when the pin 11 is vibrated. According to the capacitor model and the pin 11 structure, it is set from the connection between the pin 11 and the capacitor body 1 to the end of the pin 11 and the side close to the clamping groove 12 in this embodiment.
[0127] The poking rate refers to the speed parameter of the reciprocating movement of the pin 11 in the poking area. According to the material of the pin 11, it is determined to ensure that the cleaning effect can be achieved without damaging the pin 11.
[0128] The polishing path refers to the moving track of the polishing wheel when the pin 11 is polished. According to the shape and position of the pin 11, it is set. The polishing path in this embodiment is a route that polishes a circle around the standard pin 11.
[0129] Step 51: According to the poking rate, the pin 11 is vibrated by reciprocating movement in the poking area, and the vibration amplitude is collected.
[0130] The vibration amplitude refers to the maximum displacement of the pin 11 from the original static position during the vibration process, which is obtained by the vibration sensor preset on the poking rod.
[0131] The poking rod is preset on one side of the pin 11 and is in contact with the pin 11, and then reciprocates in the poking area. When the poking rod passes through the clamping groove 12 position, vibration is generated between the poking rod and the pin 11 to produce a knocking effect on the pin 11.
[0132] The poking rod is a rod-shaped structure preset on one side of the pin 11, which can be driven by a mechanical hand to move in multiple axes, and has rigidity itself.
[0133] Step 520: When the vibration amplitude is 0, the capacitor body 1 is rejected.
[0134] The vibration amplitude of 0 represents that the poking rod has no effect on the pin 11, that is, it is determined that the pin 11 is seriously corroded and separated at this time. The corresponding capacitor body 1 is unqualified product, and the mechanical hand is controlled to grab and transport it to the recycling equipment for rejection.
[0135] Step 521: When the vibration amplitude is not 0, the pin 11 is polished according to the polishing path, and light is emitted to the pin 11 at the emission wavelength and moved along the detection path. The reflected wavelength is collected during the movement.
[0136] The vibration amplitude not being 0 represents that the pin 11 is not separated. The system controls the preset polishing wheel to approach the pin 11 and polish along the polishing path. After polishing, light is emitted again and the reflected wavelength is collected.
[0137] Step 5210: When the reflected wavelength does not conform to the wavelength interval corresponding to the third type, it is rejected.
[0138] The reflected wavelength not meeting the wavelength interval corresponding to the third type represents that the surface of the pin 11 after polishing is still in an etched state and cannot meet the direct use standard. Even if the surface is polished again, the diameter of the pin 11 after polishing is reduced and cannot effectively cooperate with the subsequent steps. Therefore, the mechanical hand is controlled to grab and transport the pin 11 to the recycling equipment for rejection.
[0139] Step 5211: When the reflected wavelength meets the wavelength interval corresponding to the third type, no rejection is performed.
[0140] The reflected wavelength meeting the wavelength interval corresponding to the third type represents that the pin 11 after polishing has met the direct use standard, and no rejection is required, and the subsequent steps can be performed.
[0141] Reference Figure 7 The processing method further includes the following steps:
[0142] Step 53: Based on the second type, a polishing signal is sent, and the pin length and insertion times are determined according to the capacitor model.
[0143] The pin length refers to the actual length size of the pin 11, which can be directly read from the capacitor model.
[0144] The insertion times refer to the number of times the pin 11 needs to be repeatedly inserted for polishing. The corresponding insertion times are queried from the number corresponding table according to the capacitor model. The number corresponding table refers to a data table recording different capacitor models and their corresponding insertion times, which is obtained by technicians through pre-experiment and will not be described here.
[0145] Step 54: The polishing depth, assembly depth, and suction degree are determined according to the pin length.
[0146] The polishing depth is a depth parameter of the polishing tool for polishing the pin 11, which is determined according to the length from the connection of the pin 11 and the capacitor body 1 to the position of the clamping groove 12, so as to ensure that the clamping rod 31 will not be directly inserted into the clamping groove 12 when the pin 11 is inserted into the mounting seat 21 at the polishing depth.
[0147] The assembly depth refers to the depth size of the pin 11 after being inserted into the mounting seat 21 at the polishing depth, which is obtained by subtracting the polishing depth from the pin length.
[0148] The suction degree refers to the strength parameter of the suction of the debris generated during polishing. The longer the pin length, the greater the suction degree. The corresponding suction degree is queried from the suction corresponding table according to the pin length. The suction corresponding table refers to a data table recording different pin lengths and their corresponding suction degrees, which is obtained by technicians through pre-experiment and will not be described here.
[0149] Step 55: According to the polishing signal, control the needle 11 to move above the mounting seat 21 and descend to the polishing depth, and at the same time, control the suction port of the air extractor to move to the opening of the mounting seat 21 to perform suction, and the needle 11 is polished under the action of the sandpaper 26, and the debris generated by polishing is extracted by the air extractor, and then the needle 11 is reset and extracted, and the insertion and extraction are repeated based on the number of insertions.
[0150] After the system senses the polishing signal, the mechanical claw is controlled to clamp the capacitor body 1 to drive the needle 11 to move above the mounting seat 21, and then the needle 11 is inserted into the mounting groove 212 by descending to the polishing depth, and the suction port of the air extractor is controlled to move to the opening of the mounting seat 21 to perform suction, and the needle 11 is polished under the action of the sandpaper 26, and the debris generated by polishing is extracted by the air extractor, and then the needle 11 is reset and extracted, and the insertion and extraction are repeated based on the number of insertions.
[0151] Step 56: Stop suction when the number of insertions is reached, and control the needle 11 to insert the mounting seat 21 to the assembly depth.
[0152] After the needle 11 is inserted into the mounting seat 21 and reaches the number of insertions, it is inserted again to the assembly depth to complete the assembly.
[0153] The straightening method includes the following steps:
[0154] Step 40: Determine the tensioning vector, winding position, and movement vector according to the capacitor model.
[0155] The tensioning vector includes tensioning strength and tensioning direction.
[0156] The tensioning strength refers to the magnitude of the tension applied to the flexible rope after winding around the needle 11, which is determined by reading the needle hardness from the capacitor model. The greater the needle hardness, the greater the tensioning strength.
[0157] The tensioning direction refers to the direction of the tension applied to the flexible rope after winding around the needle 11. In this embodiment, it is two directions that are oppositely arranged and perpendicular to the extension direction of the needle 11.
[0158] The winding position refers to the position of the flexible rope winding on the surface of the needle 11, which is the connection between the needle 11 and the capacitor body 1 in this embodiment.
[0159] The movement vector includes movement length and movement direction.
[0160] The movement length refers to the length of the movement of the wound flexible rope along the needle 11, which in this embodiment refers to the distance from the connection between the needle 11 and the capacitor body 1 to the clamping groove 12, i.e. the same value as the polishing depth.
[0161] The movement direction refers to the direction of the movement of the wound flexible rope along the needle 11, which in this embodiment refers to the direction of extending along the needle 11 to move away from the capacitor body 1, which is perpendicular to the surface of the capacitor body 1.
[0162] Step 41: winding the needle 11 according to the winding position and fixing it with the tension vector, collecting the tension of both ends at this time and defining it as the reference force, and then moving with the movement vector.
[0163] The reference force refers to the force value collected from both ends of the flexible rope when the flexible rope is wound on the needle 11 at the winding position, which is detected by the tension sensor preset at both ends of the flexible rope. Since the winding position is located at the connection between the needle 11 and the capacitor body 1, there is no inclination, and the force value at this time is taken as the reference value.
[0164] The winding position of the middle part of the flexible rope close to the needle 11 is controlled, and then one end of the flexible rope is wound around the needle 11. The two ends of the flexible rope are straightened along the tension direction with a tension force, and then the two ends of the flexible rope are moved along the movement direction and the movement length. At this time, the flexible rope drives the needle 11 to correct and move to the clamping groove 12, and the diameter of the clamping groove 12 is smaller, so that the flexible rope no longer restricts the needle 11.
[0165] In this embodiment, after the winding of the first flexible rope is completed, another flexible rope is wound at the winding position, and the two flexible ropes are perpendicular to each other and arranged horizontally.
[0166] Step 42: After the movement stops, the tension of both ends is collected.
[0167] The tension refers to the force value collected from both ends of the flexible rope, which is detected by the tension sensor preset at both ends of the flexible rope.
[0168] Step 430: when the tension is 0, the straightening process of the needle 11 is completed.
[0169] The tension of 0 represents that after the flexible rope moves to the clamping groove 12, the flexible rope no longer closely adheres to the needle 11 due to the smaller diameter of the clamping groove 12, and the needle 11 does not rebound, completing the straightening process of the needle 11.
[0170] Step 4310: when the tension is not 0, the adjustment vector is determined according to the tension.
[0171] The tension not being 0 represents that after the flexible rope moves to the clamping groove, the needle 11 recovers the bending state under the action of its own elastic force, thereby exerting force on the flexible rope.
[0172] The adjustment vector refers to the control data required to correct the needle 11 to the standard straightening state. The greater the tension, the more the needle 11 deviates in the opposite direction, and the greater the adjustment force in the corresponding direction in the adjustment vector.
[0173] As the tension of the two ends of a flexible rope is set as a1 and a2 respectively, and the tension of the two ends of another flexible rope is set as b1 and b2 respectively, when a1 is greater than a2, a1 needs to be pulled to adjust, the greater the difference between a1 and a2, the greater the force applied, and the adjustment method of b1 and b2 is the same, and the value set of a1, a2, b1 and b2 is the adjustment vector.
[0174] Step 4311: According to the adjustment vector, the two ends of the pin 11 are controlled to correct and collect the tension in real time.
[0175] The two ends of the two flexible ropes are controlled by the adjustment vector to drive the pin 11 to correct, and the flexible rope moves to overcome the elastic force of the pin 11, so that the tension collected at the two ends of the flexible rope changes continuously.
[0176] Step 4312: Stop correcting when the tension is equal to the reference tension to make the pin 11 restore to the standard straight state.
[0177] The tension equal to the reference tension represents that the pin 11 reverses the bending under the action of the flexible rope, so that the pulling tension of the flexible rope is equal to the reference tension, and at this time, the flexible rope is released to limit the pin 11, and the pin 11 will restore to the standard straight state under the action of the elastic force.

It should be pointed out that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
