Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a capacitor and a method for controlling the capacitor thereto. Background Technology

[0002] Capacitors are core energy storage components in electronic circuits. Their core functions include storing charge, filtering, coupling, and blocking DC. They are typically composed of two electrodes sandwiching an insulating dielectric layer.

[0003] Currently, capacitors are typically fixed by soldering the positive and negative terminals to the live and neutral wires using a soldering iron or hot air gun. Three-phase capacitors, however, have four pins that connect to the three live wires and one neutral wire, and these pins need to be soldered to the corresponding live and neutral wires.

[0004] However, with this installation method, if there is an oxide layer on the contact pin, direct soldering will increase the resistance and thus affect the performance of the capacitor. Summary of the Invention

[0005] To reduce the impact of the oxide layer on the pins, this invention provides a capacitor and a method for controlling the same.

[0006] In a first aspect, the present invention provides a capacitor that adopts the following technical solution: A capacitor includes a capacitor body with pins, wherein the pins are provided with snap-fit ​​grooves for mounting, and further includes a snap-fit ​​structure for fixing the pins, a grinding structure for grinding the outer side of the pins during the pin snap-fit ​​process, and a base plate with connecting terminals. The polishing structure includes: The mounting base is installed on the base plate and has a mounting groove on its inner side for inserting the pins. The pressure plate is slidably mounted inside the snap-fit ​​groove and moves with the pin when it is inserted; A first spring, located inside the mounting groove and between the mounting base and the pressure plate, is used to drive the pressure plate to always tend to move away from the mounting groove; A threaded cylinder is rotatably mounted inside the mounting base and is used to rotate when the pin is inserted; A drive mechanism is disposed between the pressure plate and the threaded cylinder, and is used to move with the pressure plate to drive the threaded cylinder to rotate; Sandpaper is fixedly installed inside the threaded cylinder and is tightly attached to the needle when the needle is inserted. The sandpaper rotates with the threaded cylinder to polish the outside of the needle. The snap-fit ​​structure includes: A snap-fit ​​rod extends through one side of the mounting base and slides to be close to or away from the pin. It is used to insert into the snap-fit ​​groove to snap and fix the pin. At the same time, the snap-fit ​​rod is electrically connected to the pin and to the connection terminal. The mounting plate is fixedly installed on the base plate and located on one side of the snap-fit ​​rod. The mounting plate is used for sliding installation of the snap-fit ​​rod. A second spring is installed between the locking rod and the mounting plate, and always tends to push the locking rod closer to the locking groove.

[0007] By adopting the above technical solution, when the pins of the capacitor body are inserted into the mounting slot of the mounting base, the pressure plate is squeezed and moved by the pins. The drive mechanism drives the threaded cylinder to rotate, so that the sandpaper on the inside of the threaded cylinder polishes the outside of the pins to remove the oxide layer and ensure conductivity. After polishing, the locking rod is inserted into the locking slot of the pin under the action of the second spring to achieve fixed installation and electrical connection.

[0008] Optionally, the pressure plate has a communication port for connecting the lower and upper parts of the pressure plate to allow conductive liquid pre-installed in the mounting groove to pass through. The upper part of the pressure plate has a flow groove communicating with the communication port. The flow groove is used to allow conductive liquid to pass through when the pin abuts against the pressure plate.

[0009] By adopting the above technical solution, the connecting port and flow groove on the pressure plate can allow the conductive liquid in the mounting groove to flow to the surface of the pin when the pin is inserted, forming a conductive dielectric layer at the contact point between the pin and the snap-fit ​​rod, further reducing the contact resistance and improving the stability of the electrical connection.

[0010] Optionally, the mounting base also has a disassembly cover rotatably connected to the threaded cylinder, the disassembly cover being detachably connected to the mounting base and used for replacing the sandpaper inside the threaded cylinder after quick disassembly and assembly.

[0011] By adopting the above technical solution, the detachable connection design between the disassembly cover and the mounting base facilitates quick disassembly and assembly of the threaded cylinder, thereby enabling the replacement and maintenance of sandpaper and solving the problem of inconvenient replacement after sandpaper wear.

[0012] Optionally, the latching rod has a boss, and the top of the boss is set as an inclined surface; The snap-fit ​​structure also includes: A limiting plate is connected to the latching rod and driven by the capacitor body to move the latching rod into or away from the latching slot. The limiting plate has a through slot for the latching rod to pass through and a receiving slot for accommodating the boss when the latching rod is inserted into the latching slot. The receiving slot is inclined to fit the inclined surface above the boss and is used to push the boss away from the latching slot when the limiting plate moves down to unlock the latching rod. A third spring is installed between the base plate and the limiting plate, and always has the tendency to push the limiting plate away from the base plate.

[0013] By adopting the above technical solution, the limiting plate is pressed down by the capacitor body. When the receiving groove moves to the position of the locking rod, the second spring pushes the boss on the locking rod to make the locking rod enter the locking groove to complete the locking. If the limiting plate is pressed down further, the inclined surface of the receiving groove pushes the boss of the locking rod, so that the locking rod overcomes the elastic force of the second spring and moves away from the locking groove, thereby unlocking.

[0014] Optionally, a support plate for supporting the capacitor body is fixedly installed on the limiting plate; a housing that is slidably installed in contact with the support plate is fixedly installed on the bottom plate, and a through groove is provided on the housing for the snap-fit ​​rod to pass through for limiting; a pressing plate is fixedly installed below the support plate, and the pressing plate extends to the outside of the housing for manual pressing.

[0015] By adopting the above technical solution, the support plate plays a supporting and positioning role for the capacitor body, improving stability; the pressing plate extends to the outside of the shell, making it easy to manually press and control the downward movement of the limiting plate, simplifying the unlocking operation.

[0016] Optionally, a detection plate is also installed on the pressing plate, the detection plate has a detection port, the detection port is electrically connected to the snap-fit ​​rod, and the outer shell has a through hole for exposing the detection port.

[0017] By adopting the above technical solution, the detection port on the detection board is electrically connected to the snap-fit ​​rod, and external detection equipment can be connected to detect the conduction status or performance parameters of the capacitor in real time, which facilitates detection during the assembly process.

[0018] Secondly, this application provides a method for controlling a capacitor, which adopts the following technical solution: A method for controlling a capacitor, applied to a capacitor, comprising: Step 1: Respond to the trigger information to obtain the capacitor model, reference position range, and detection information at the detection position; Step 2: Determine the emission wavelength and detection path of the pins based on the capacitor model; Step 3: Based on the detection information, emit light at the pin with the emission wavelength and move it along the detection path. During the movement, collect the reflected wavelength and then determine the reflection position range based on the reflected wavelength. Step 4: When the reflection position interval is inconsistent with the reference position interval, the corresponding position of the reflection 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 reflection wavelength. The corrosion types include primary type, secondary type and tertiary type. Step 5: Grind and assemble the pins according to the preset processing method based on the corrosion type.

[0019] By adopting the above technical solution, based on photoelectric detection to identify the abnormal position and degree of corrosion of the pins, the pins are straightened and classified for targeted grinding and assembly, thus realizing automated pin processing.

[0020] Optionally, the processing method includes a polishing method, which includes: Step 50: Based on the primary type, determine the reference dimensions, actuation area, actuation speed, and polishing path according to the capacitor model; Step 51: Move the pin back and forth in the agitation area according to the agitation rate to vibrate the pin and collect the vibration amplitude. Step 520: When the vibration amplitude is 0, remove the capacitor body; Step 521: When the vibration amplitude is not 0, polish the pin according to the polishing path, emit light to the pin with the emission wavelength and move along the detection path, and collect the reflected wavelength during the movement. Step 5210: If the reflected wavelength does not conform to the wavelength range corresponding to the third-level type, it shall be rejected; Step 5211: When the reflected wavelength matches the wavelength range corresponding to the third-level type, it is not rejected.

[0021] By adopting the above technical solution, for the first-level type, a special flicking method is used to vibrate the pins, causing impurities on the outside of the pins to peel off. At the same time, the capacitor body corresponding to the severely corroded and detached pins is removed. Then, the polishing effect is confirmed by light secondary inspection to ensure that it meets the standards of the third-level type and improve product quality.

[0022] Optionally, the processing methods also include: Step 53: Issue a polishing signal based on the secondary type, and determine the pin length and number of insertions according to the capacitor model; Step 54: Determine the grinding depth, assembly depth, and suction force based on the pin length; Step 55: According to the grinding signal, control the pin to move to the top of the mounting base and descend to the grinding depth. At the same time, use suction force to suction the opening above the mounting base. After reaching the grinding depth, reset and repeat insertion, while counting. Step 56: Stop suction when the number of insertions is reached and control the pins to insert into the mounting base at the appropriate depth.

[0023] By adopting the above technical solution, for the secondary type, the grinding depth and number of insertions are set according to the pin length. The suction function is used to remove the debris generated during grinding. Multiple grinding cycles are performed to ensure that the oxide layer is completely removed, and the installation is finally completed at the assembly depth.

[0024] Optional straightening methods include: Step 40: Determine the tension vector, winding position, and movement vector according to the capacitor model; Step 41: Wrap the needle according to the wrapping position and fix it with the tension vector. Collect the tension at both ends at this time and define it as the reference force. Then move it with the movement vector. Step 42: After the movement stops, collect the tensile force at both ends; Step 430: When the tensile force is 0, complete the straightening process of the needle; Step 4310: When the tensile force is not zero, determine the adjustment vector based on the tensile force; Step 4311: Control the pins at both ends according to the adjustment vector and collect the tensile force in real time; Step 4312: Stop the correction when the tension is equal to the reference tension so that the stitches are restored to the standard straight state.

[0025] By adopting the above technical solution, the tension vector, winding position and movement vector are determined according to the capacitor model. First, the pins are wound and fixed and the reference force is collected. Then, the movement is based on the movement vector. By collecting the tension force at both ends of the winding in real time, dynamic correction is performed according to the adjustment vector according to different situations until the tension force is consistent with the reference force, thus achieving precise correction of the pins.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: When the pins of the capacitor body are inserted into the mounting slot of the mounting base, the pressure plate is squeezed and moved by the pins. The drive mechanism drives the threaded cylinder to rotate, so that the sandpaper on the inside of the threaded cylinder polishes the outside of the pins to remove the oxide layer and ensure conductivity. After polishing, the locking rod is inserted into the locking slot of the pin under the action of the second spring to achieve fixed installation and electrical connection. The limiting plate moves downward under the pressure of the capacitor body. When the receiving groove moves to the position of the locking rod, the second spring pushes the boss on the locking rod to make the locking rod enter the locking groove to complete the locking. If the limiting plate continues to be pressed down, the inclined surface of the receiving groove pushes the boss of the locking rod, so that the locking rod overcomes the elastic force of the second spring and moves away from the locking groove, thereby unlocking. Based on photoelectric detection to identify pin location anomalies and corrosion levels, pins are straightened and classified for targeted grinding and assembly, achieving automated pin processing.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This invention discloses a capacitor.

[0031] Reference Figure 1 and Figure 2A capacitor includes a capacitor body 1, multiple polishing structures 2, multiple snap-fit ​​structures 3, a base plate 4, a shell 5, a support plate 6, a pressing plate 7, and a detection plate 8.

[0032] The lower part of the capacitor body 1 is fixedly connected with multiple pins 11, and the pins 11 are provided with snap-fit ​​grooves 12.

[0033] The base plate 4 has multiple connection terminals 41 corresponding to the pins 11, which are used to connect to the external neutral or live wire.

[0034] Reference Figure 3 and Figure 4 Multiple grinding structures 2 are set one-to-one with pins 11. The grinding structure 2 includes a mounting base 21, a pressure plate 22, a first spring 23, a drive mechanism 24, a threaded cylinder 25, and sandpaper 26.

[0035] Mounting base 21 is fixedly mounted on base plate 4 and has mounting groove 212 on its inner side for inserting pin 11. Sliding grooves 213 are provided on both sides of mounting groove 212 for limiting the pressure plate 22. Removal cover 211 is threadedly connected to the upper part of mounting base 21.

[0036] The pressure plate 22 is located inside the mounting groove 212 and slides up and down along the mounting base 21. The pressure plate 22 has a communication port 221 for connecting the lower and upper parts of the pressure plate 22 to allow the conductive liquid preset inside the mounting groove 212 to pass through. The pressure plate 22 has a flow groove 222 above it that communicates with the communication port 221. The flow groove 222 is composed of an inner ring groove and an outer ring groove. A notch is provided between the inner ring groove and the outer ring groove for communication. The flow groove 222 is used to allow the conductive liquid to pass through when the pin 11 abuts against the pressure plate 22.

[0037] The first spring 23 is located inside the mounting groove 212 and its two ends are fixedly connected to the mounting base 21 and the pressure plate 22 respectively. The first spring 23 always has the tendency to drive the pressure plate 22 away from the mounting groove 212.

[0038] The drive mechanism 24 consists of a drive rod 241 symmetrically arranged on the pressure plate 22 and a protrusion 242 located at the end of the drive rod 241. The drive rod 241 is limited to slide in the sliding groove 213.

[0039] The threaded cylinder 25 is located inside the mounting groove 212 and is rotatably connected to the disassembly cover 211. The outer side of the threaded cylinder 25 has a threaded groove that slides and engages with the protrusion 242.

[0040] Sandpaper 26 is fixedly installed inside the threaded cylinder 25 for polishing the pins 11.

[0041] In use, the conductive liquid is injected into the mounting groove 212, and then the pins 11 of the capacitor body 1 are inserted into the mounting groove 212. The pins 11 drive the pressure plate 22 to compress the first spring 23. The pressure plate 22 drives the drive rod 241 to move down along the sliding groove 213. The drive rod 241 drives the protrusion 242 to move along the threaded groove on the outside of the threaded cylinder 25 to drive the threaded cylinder 25 to rotate along the disassembly cover 211. The threaded cylinder 25 drives the sandpaper 26 to rotate, thereby polishing the outside of the pins 11 to remove the oxide layer and avoid increasing the resistance of the pins 11, which would affect the normal use of the capacitor. While the pressure plate 22 moves down, it squeezes the conductive liquid, causing the conductive liquid to move to the outside of the pins 11 through the connecting port 221 and the flow groove 222, which further improves the conductivity between the pins 11 and the snap-fit ​​rod 31.

[0042] The snap-fit ​​structure 3 includes a snap-fit ​​rod 31, a mounting plate 32, a second spring 33, a limiting plate 34, and a third spring 35.

[0043] Reference Figure 3 and Figure 5 The latching rod 31 is slidably mounted on the mounting plate 32, with one end penetrating one side of the mounting base 21. One end of the latching rod 31 is inserted into the latching groove 12 and latches with the pin 11. At the same time, the latching rod 31 abuts against the outside of the pin 11 to achieve electrical connection. Multiple latching rods 31 are electrically connected to a connecting terminal 41, so that when the pin 11 of the capacitor body 1 is connected to the latching rod 31, the capacitor body 1 is electrically connected to the live wire and the neutral wire through the connecting terminal 41. A boss 311 is integrally provided on the latching rod 31, and the top of the boss 311 is set as an inclined surface.

[0044] Mounting plate 32 is fixedly mounted on base plate 4. Second spring 33 is sleeved on the outside of snap-fit ​​rod 31 and its two ends are fixedly connected to boss 311 and mounting plate 32 respectively. Second spring 33 always has the tendency to push snap-fit ​​rod 31 closer to snap-fit ​​groove 12.

[0045] The limiting plate 34 is slidably connected to the locking rod 31. The limiting plate 34 has a through groove 342 for the locking rod 31 to pass through and slide up and down. The limiting plate 34 also has a receiving groove 341 for accommodating the boss 311 when the locking rod 31 is inserted into the locking groove 12. The receiving groove 341 is inclined to fit the inclined surface above the boss 311. When the limiting plate 34 moves down, it pushes the boss 311 away from the locking groove 12 to unlock the locking rod 31 from the pin 11.

[0046] The third spring 35 is fixedly installed between the limiting plate 34 and the base plate 4 and always tends to push the limiting plate 34 away from the base plate 4.

[0047] In use, the capacitor body 1 moves downward, causing the limiting plate 34 to compress the third spring 35. At this time, the boss 311 on the locking rod 31 abuts against the limiting plate 34 under the action of the second spring 33 and slides along the surface of the limiting plate 34. When the pin 11 is fully inserted into the mounting groove 212, the receiving groove 341 on the limiting plate 34 moves to the position of the boss 311. The boss 311 moves into the receiving groove 341 under the action of the second spring 33, and at the same time, the locking rod 31 inserts into the locking groove 12 to complete the locking and fixing. This eliminates the need for fixing with bolts or welding, improving installation speed and reducing installation difficulty.

[0048] Reference Figures 1 to 5 The outer casing 5 is fixedly installed on the base plate 4 and located outside the multiple snap-fit ​​structures 3 for protection. The outer casing 5 has a through groove for the snap-fit ​​rod 31 to pass through, an opening for the pressing plate 7 to extend to the outside, and a through hole for use with the detection plate 8. The snap-fit ​​rod 31 passes through the through groove on the outer casing 5 and is slidably connected to the outer casing 5.

[0049] The support plate 6 is fixedly installed above the limiting plate 34 and is slidably connected to the outer shell 5.

[0050] The pressing plate 7 is U-shaped and fixedly installed below the support plate 6. One end of the pressing plate 7 extends to the outside through the opening on the outer shell 5 for easy manual pressing.

[0051] The detection plate 8 is fixedly installed at the lower end of the pressing plate 7. The detection plate 8 has multiple detection ports 81. The detection ports 81 correspond one-to-one with the snap rods 31 and are electrically connected. When the pins 11 are inserted into the mounting slots 212, the detection ports 81 are exposed through the through holes on the outer shell 5 to facilitate external detection and connection.

[0052] During use, the support plate 6 supports the capacitor body 1 as it moves downwards, simultaneously causing multiple limiting plates 34 to move downwards synchronously. During disassembly, the pressing plate 7 is pressed downwards, causing the support plate 6 and limiting plates 34 to move sequentially. The boss 311 moves along the inclined surface of the receiving groove 341 and compresses the second spring 33, thereby causing the locking rod 31 to slowly disengage from the locking groove 12. When the locking rod 31 is completely disengaged from the locking groove 12, the first spring 23 pushes the pressure plate 22 and pin 11 upwards, allowing the capacitor body 1 to be completely removed. This achieves rapid disassembly of the capacitor body 1 without the need for other tools, facilitating replacement or repair of the capacitor body 1. When the capacitor body 1 is installed, the detection plate 8 moves with the support plate 6 to the through hole of the housing 5, and the detection port 81 is exposed for the testing equipment to connect for testing. There is no need to disassemble the capacitor body 1 or disconnect the connection terminal 41 for testing, which improves the convenience of testing. When the capacitor body 1 is disassembled, the detection plate 8 moves upward with the support plate 6 under the action of the third spring 35, so that the detection port 81 is blocked by the housing 5, avoiding accidental damage when not in use.

[0053] Based on the same inventive concept, embodiments of the present invention provide a method for controlling a capacitor.

[0054] refer to Figure 6 A method for controlling a capacitor includes the following steps: Step 1: Respond to the trigger information to obtain the capacitor model, reference position range, and detection information in the detection position.

[0055] Trigger information refers to the trigger signal that starts the capacitor detection and processing process. It can be output through equipment operation instructions or manual operation instructions. Specifically, it can refer to the start switch of the entire process when the operator clicks the start button on the operation panel.

[0056] The capacitor model number is a specific number or code that identifies the capacitor's specifications and parameters, including information such as product size, number of pins, and characteristics. It is obtained by scanning the QR code on the capacitor body 1 and matching it with the database. The QR code is affixed to the capacitor body 1 when it is manufactured.

[0057] The reference position range is the standard position range that pointer pin 11 should be in. It is determined based on the design specifications and production standards of this type of capacitor and is pre-entered into the database by the staff.

[0058] The detection position refers to the specific location where the capacitor body 1 should be when it is being tested. This is determined by the staff entering the pre-set position information into the database and then having the system read it.

[0059] The detection information refers to the signal emitted when the capacitor body 1 to be detected is identified at the detection location. The signal can be determined by obtaining the pressure at the detection location through a pressure sensor.

[0060] When the system senses the trigger information, it reads the capacitor model and reference position range from the database, and at the same time senses the detection information to ensure that the capacitor body 1 to be detected exists at the detection position, so as to carry out subsequent processing steps.

[0061] Step 2: Determine the emission wavelength and detection path of pin 11 based on the capacitor model.

[0062] The emission wavelength is the wavelength parameter of the light emitted by the laser emitter during detection. It is obtained by reading the material of pin 11 from the capacitor model and looking up the corresponding wavelength parameter from the wavelength correspondence table based on the material of pin 11. The wavelength correspondence table is a data table that records different pin materials and their corresponding wavelength parameters. It is obtained by technicians through prior testing and will not be elaborated here.

[0063] The wavelength of light emitted after reflection when it hits the surface of pin 11 will be attenuated. The degree of attenuation varies depending on the material of the pin 11, so the emission wavelength needs to be matched according to the pin material.

[0064] The detection path is the trajectory of light during the detection process. It is pre-planned and set by reading the pin shape, distribution, and detection range from the capacitor model.

[0065] Step 3: Based on the detection information, emit light at the emission wavelength toward pin 11 and move along the detection path. During the movement, collect the reflected wavelength and then determine the reflection position range based on the reflected wavelength.

[0066] The reflected wavelength refers to the wavelength of the light reflected back from the surface of pin 11 after the light shines on pin 11. It is obtained in real time by the detection device as the light moves along the detection path.

[0067] The reflection position range refers to the actual position range of the reflected light from pin 11 during light detection, which is determined by real-time acquisition of the reflected wavelength and calculation of the corresponding position coordinates.

[0068] After the system senses the detection information, it controls the laser emitter preset on one side of the detection position to emit light at the emitted wavelength and move along the detection path, while controlling the detection equipment to collect the reflected light.

[0069] As the light moves, it will not be reflected when it shines on a position without pin 11, so the reflected wavelength cannot be obtained. When it shines on a position with pins, the reflected light will be collected to determine the reflected wavelength and the range of the reflected position.

[0070] Step 4: When the reflection position interval is inconsistent with the reference position interval, the corresponding position of the reflection 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 reflection wavelength. The corrosion types include primary type, secondary type and tertiary type.

[0071] The inconsistency between the reflection position range and the reference position range indicates that the pin 11 corresponding to the reference position range is tilted, thus changing its original position.

[0072] An abnormal position refers to the position of pin 11 where the reflection position interval does not coincide with the reference position interval. This is determined by comparing the two.

[0073] The preset straightening method is a standardized operating procedure for correcting pins 11 in abnormal positions, which is compiled and stored in the system according to different capacitor models.

[0074] The corrosion type is classified according to the degree of corrosion on the surface of pin 11. It is divided into three types: primary, secondary and tertiary. The type is determined by detecting the reflected wavelength and comparing it with the wavelength range corresponding to each level.

[0075] In this embodiment, the first-level type represents pin 11 that is severely corroded, prone to bending and irreversible damage, or easily falls off. Its metallic luster is usually below 40 GU, and the oxidation percentage is above 30%. The second-level type represents pin 11 that is slightly corroded, with an oxide layer on its surface that affects normal use. Its metallic luster is usually between 40 and 80 GU, and the oxidation percentage is between 5% and 30%. The third-level type represents pin 11 that is almost uncorroded and can be used directly. Its metallic luster is usually between 80 and 100 GU, and the oxidation percentage is less than 5%.

[0076] The processing method includes a polishing method, which includes the following steps: Step 50: Based on the primary type, determine the actuation area, actuation rate, and polishing path according to the capacitor model.

[0077] The actuation area is the operating range when the pin 11 is vibrated. It is set according to the capacitor model and the structure of the pin 11. In this embodiment, it is the area from the connection between the pin 11 and the capacitor body 1 to the end of the pin 11 and the side near the snap-fit ​​groove 12.

[0078] The agitation rate refers to the speed parameter of the reciprocating movement of the pin 11 within the agitation area. It is determined according to the material of the pin 11 to ensure that the cleaning effect is achieved without damaging the pin 11.

[0079] The polishing path refers to the movement trajectory of the polishing wheel when polishing the pin 11, and it is set according to the shape and position of the pin 11. In this embodiment, the polishing path is a route that polishes around a standard pin 11.

[0080] Step 51: Move the pin 11 back and forth in the agitation area according to the agitation rate to vibrate it, and collect the vibration amplitude.

[0081] The vibration amplitude is the maximum displacement of pointer foot 11 from its original static position during the vibration process, which is acquired in real time by a vibration sensor preset on the toggle bar.

[0082] The control lever, which is preset on one side of the pin 11, moves back and forth in the toggle area after it comes into contact with the pin 11. When the lever passes the position of the snap-fit ​​groove 12, it vibrates with the pin 11 to produce a knocking effect on the pin 11.

[0083] The lever is a rod-shaped structure pre-installed on one side of pin 11. It can be driven by a robotic arm to move in multiple axes and is rigid in itself.

[0084] Step 520: When the vibration amplitude is 0, remove the capacitor body 1.

[0085] A vibration amplitude of 0 indicates that the actuating bar has no effect on pin 11. This means that pin 11 is detached due to severe corrosion, and the corresponding capacitor body 1 is a defective product. The robotic arm is then controlled to grab it and transport it to the recycling equipment for rejection.

[0086] Step 521: When the vibration amplitude is not 0, polish the pin 11 according to the polishing path, emit light to the pin 11 with the emission wavelength and move along the detection path, and collect the reflected wavelength during the movement.

[0087] If the vibration amplitude is not 0, it means that pin 11 has not fallen off. The system controls the preset polishing wheel to approach pin 11 and polish along the polishing path. After polishing, light is emitted again and the reflected wavelength is collected.

[0088] Step 5210: If the reflected wavelength does not conform to the wavelength range corresponding to the third-level type, it shall be rejected.

[0089] If the reflected wavelength does not conform to the wavelength range corresponding to the third type, it means that the surface of the polished pin 11 is still in a corroded state and cannot meet the standard for direct use. Even if the surface is polished again, the diameter of the polished pin 11 is reduced and cannot be effectively used in subsequent steps. Therefore, the robotic arm is controlled to grab it and transport it to the recycling equipment for rejection.

[0090] Step 5211: When the reflected wavelength matches the wavelength range corresponding to the third-level type, it is not rejected.

[0091] If the reflected wavelength matches the wavelength range corresponding to the third-level type, it means that the polished pin 11 has reached the standard for direct use, so there is no need to remove it, and subsequent steps can be carried out.

[0092] Reference Figure 7 The processing method also includes the following steps: Step 53: Issue a polishing signal based on the secondary type, and determine the pin length and number of insertions according to the capacitor model.

[0093] The pin length refers to the actual length of pin 11, which can be directly read from the capacitor model number.

[0094] The number of insertions refers to the number of times that pin 11 needs to be repeatedly inserted and polished. The corresponding number of insertions can be found in the number of insertions correspondence table according to the capacitor model. The number of insertions correspondence table is a data table that records different capacitor models and their corresponding number of insertions. It is obtained by technicians through prior testing and will not be described in detail here.

[0095] Step 54: Determine the grinding depth, assembly depth, and suction force based on the pin length.

[0096] The grinding depth is the depth parameter by which the grinding tool grinds the pin 11. It is determined based on the length from the connection point of the pin 11 and the capacitor body 1 to the position of the snap-fit ​​groove 12, ensuring that when the pin 11 is inserted into the mounting base 21 at the grinding depth, the snap-fit ​​rod 31 will not be directly inserted into the snap-fit ​​groove 12.

[0097] The assembly depth is the depth to which the pointer pin 11 is fully inserted into the mounting base 21 after the grinding depth is reached. It is obtained by calculating the difference between the pin length and the grinding depth.

[0098] Suction strength refers to the intensity parameter of suctioning the debris produced during the grinding process. The longer the pin length, the greater the suction strength. The corresponding suction strength can be found in the suction correspondence table according to the pin length. The suction correspondence table is a data table that records different pin lengths and their corresponding suction strengths. It is obtained by technicians through prior testing and will not be elaborated here.

[0099] Step 55: According to the grinding signal, control the pin 11 to move above the mounting base 21 and descend to the grinding depth. At the same time, use suction force to suck up the opening above the mounting base 21. After reaching the grinding depth, reset and repeat insertion, while counting.

[0100] After the system senses the grinding signal, it controls the mechanical claw to grip the capacitor body 1 to drive the pin 11 to move above the mounting base 21. Then, it lowers the grinding depth to insert the pin 11 into the mounting groove 212. At the same time, it controls the suction port of the vacuum pump to move to the opening above the mounting base 21 for suction. The pin 11 is ground by the sandpaper 26. The debris generated by grinding is removed by the vacuum pump. Then, the pin 11 is reset and pulled out. The insertion and extraction are repeated based on the number of insertions.

[0101] Step 56: Stop suction when the number of insertions is reached and control pin 11 to insert into mounting base 21 at the assembly depth.

[0102] After the pin 11 is inserted into the mounting base 21 and reaches the required number of insertions, it is inserted again to the assembly depth to complete the assembly.

[0103] The straightening method includes the following steps: Step 40: Determine the tension vector, winding position, and movement vector according to the capacitor model.

[0104] The tension vector includes the tension force and the tension direction.

[0105] The tension refers to the amount of force applied to both sides after the flexible rope is wrapped around the needle 11. It is determined by reading the needle hardness from the capacitor model. The greater the needle hardness, the greater the tension.

[0106] The tensioning direction refers to the direction of the tension applied to both sides after the flexible rope is wrapped around the needle 11. In this embodiment, it refers to two directions that are set opposite to each other and perpendicular to the extension direction of the needle 11.

[0107] The winding position refers to the position where the flexible rope is wound around the surface of the pin 11. In this embodiment, it is the connection point between the pin 11 and the capacitor body 1.

[0108] The movement vector includes the movement length and the movement direction.

[0109] The moving length refers to the length by which the flexible rope after winding moves along the pin 11. In this embodiment, it refers to the distance from the connection between the pin 11 and the capacitor body 1 to the position of the snap-fit ​​groove 12, which is numerically the same as the grinding depth.

[0110] The direction of movement refers to the direction in which the wound flexible rope moves along the pin 11. In this embodiment, it refers to the direction that extends along the pin 11 away from the capacitor body 1 and is perpendicular to the surface of the capacitor body 1.

[0111] Step 41: Wrap the needle 11 according to the winding position and fix it with the tension vector. Collect the tension at both ends at this time and define it as the reference force, and then move it with the movement vector.

[0112] The reference force refers to the force value collected from both ends of the flexible rope when it is wound around the needle 11. It is obtained by detecting the force through tension sensors 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 tilting, and the force value at this time is used as the reference value.

[0113] Control the middle of the flexible rope near the winding position of the needle 11, then wind one end of the flexible rope around the needle 11. Tighten both ends of the flexible rope in the tension direction with tension force, and then control both ends of the flexible rope to move in the moving direction and moving length. At this time, the flexible rope drives the needle 11 to be corrected and moved to the snap-fit ​​groove 12. The diameter of the snap-fit ​​groove 12 is small, so that the flexible rope no longer restricts the needle 11.

[0114] In this embodiment, after the first flexible rope is wound, another flexible rope is wound at the winding position, and the two flexible ropes are perpendicular to each other and set horizontally.

[0115] Step 42: After the movement stops, collect the tensile force at both ends.

[0116] Tensile force refers to the force value collected from both ends of the flexible rope, which is obtained by the tension sensors preset at both ends of the flexible rope.

[0117] Step 430: When the tensile force is 0, complete the straightening process of the needle 11.

[0118] A tensile force of 0 indicates that after the flexible rope moves to the locking groove 12, due to the small diameter of the locking groove 12, the flexible rope is no longer tightly attached to the needle 11, and the needle 11 does not spring back, thus completing the straightening process of the needle 11.

[0119] Step 4310: When the tensile force is not 0, determine the adjustment vector based on the tensile force.

[0120] A non-zero tensile force indicates that after the flexible rope moves to the locking groove, the pin 11 returns to its bent state under its own elastic force, thus applying force to the flexible rope.

[0121] The adjustment vector refers to the control data required to straighten pin 11 to the standard straight state. The greater the tension, the more pin 11 deviates in the opposite direction, and the greater the adjustment force in the corresponding direction of the adjustment vector.

[0122] If the tensile forces at both ends of a flexible rope are set as a1 and a2 respectively, and the tensile forces at both ends of another flexible rope are set as b1 and b2 respectively, when a1 is greater than a2, a1 needs to be adjusted by pulling. The greater the difference between a1 and a2, the greater the force applied. The adjustment method for b1 and b2 can be obtained in the same way. The numerical set of the forces applied by a1, a2, b1 and b2 respectively is the adjustment vector.

[0123] Step 4311: According to the adjustment vector, control both ends to correct the pin 11 and collect the tensile force in real time.

[0124] The two ends of the two flexible ropes are controlled by adjusting the vector to drive the needle 11 to be corrected. The flexible ropes move against the elastic force of the needle 11, so that the tensile force collected at both ends of the flexible ropes changes continuously.

[0125] Step 4312: Stop the correction when the tension is equal to the reference tension so that the pin 11 returns to the standard straight state.

[0126] When the tension is equal to the reference tension, it means that the needle 11 is bent in the opposite direction under the action of the flexible rope, so that the tension on the flexible rope is equal to the reference tension. When the flexible rope is released from its restriction on the needle 11, the needle 11 will just return to the standard straight state under the action of the elasticity.
