Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, and specifically to an automatic winding machine for double-sided metal film used in capacitors. Background Technology

[0002] A capacitor is a fundamental electronic component, one of the three basic passive devices in electronics, used to store electrical charge. It consists of two conductors placed close together but insulated from each other. When a capacitor is connected to a power source, one plate accumulates a positive charge, and the other plate accumulates an equal amount of negative charge. This characteristic of capacitors allows them to store electric field energy and play various roles in circuits. The production process of capacitors requires a winding machine to wind the capacitor film, aluminum foil, and electrodes together in a designed configuration to form the capacitor core. It is one of the key pieces of equipment in capacitor manufacturing and is widely used in electronics, medical, communications, instrumentation, aerospace, and other fields.

[0003] In the operation of existing capacitor winding machines, the double-sided metal film needs to be conveyed to the winding mechanism by multiple conveying rollers. During the long-distance conveying, dust and other undesirable substances will adhere to the surface of the double-sided metal film. However, existing winding machines do not have a mechanism to clean the undesirable substances on the surface of the double-sided metal film. As a result, the subsequent electrical performance and quality of the capacitor component after winding are affected, reducing the service life and reliability of the capacitor. Therefore, existing winding machines still have certain drawbacks in use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an automatic winding machine for double-sided metal film for capacitors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic winding machine for double-sided metal film of capacitors includes a base plate and a vertical plate. The vertical plate is installed on the top of the base plate. A rotating frame is rotatably mounted on the front of the vertical plate. Multiple winding mechanisms for winding and forming capacitors are installed inside the rotating frame. Two fixed frames are installed on the front of the vertical plate. An air cleaning mechanism for cleaning both sides of the double-sided metal film is provided on the outer wall of the side of the two fixed frames that are close to each other. A clamping mechanism for assisting in unloading the wound capacitors is installed on the front of the vertical plate. A fixed plate is installed on the front of the vertical plate and directly below the rotating frame. A guiding mechanism for guiding the unloading of capacitors is provided on the top of the fixed plate. An auxiliary unloading mechanism for continuously unloading qualified capacitors is provided at the end of the fixed plate away from the vertical plate.

[0007] Optionally, a first motor is mounted on the back of the vertical plate, and the output end of the first motor is connected to the rotating part of the rotating frame.

[0008] Optionally, two conveying rollers are rotatably mounted on the front of the vertical plate and above the two fixed frames. A mounting frame is rotatably mounted on the bottom of each of the two fixed frames, and a limiting roller for limiting and supporting the capacitor during the winding process is mounted on the bottom of each mounting frame.

[0009] Optionally, the winding mechanism includes multiple telescopic support rods rotatably mounted on the inner walls of both sides of the rotating frame, and multiple second motors mounted on the outer wall of the rotating frame near the vertical plate, with the output ends of the multiple second motors respectively connected to the support rods adjacent to them.

[0010] Optionally, the air cleaning mechanism includes two connecting rods installed on the outer wall of two fixed frames close to each other. An air outlet is installed at the end of the two connecting rods away from the fixed frames, and both air outlets are connected to a preset air outlet device through pipes provided on the outer wall.

[0011] Optionally, the clamping mechanism includes two first sliding grooves opened on the front of the vertical plate, each of the two first sliding grooves having a first slider installed inside, each of the two first sliders having a movable plate installed at the end away from the first sliding groove, and each of the two movable plates having an arc-shaped plate installed on the outer wall of the side of the movable plates that are close to each other.

[0012] Optionally, an arc-shaped groove is provided on the outer wall of the two arc-shaped plates that are close to each other, and an electric slider is installed inside the two arc-shaped grooves. The outer wall of the two electric sliders that are close to each other is connected to a clamping plate by an electric telescopic rod.

[0013] Optionally, the guiding mechanism includes two vertical rods installed on the top of the fixed plate. A second sliding groove is provided on the outer wall of the side of the two vertical rods that are close to each other. A second slider is installed inside the two second sliding grooves. A guide plate is rotatably installed on the end of the two second sliders that is away from the second sliding groove. A through groove is provided inside the vertical plate for one end of the guide plate to rotate and adjust. An industrial camera is installed on the front of the vertical plate and near the guide plate.

[0014] Optionally, the auxiliary feeding mechanism includes an opening at the end of the fixed plate away from the vertical plate, a rotating block rotatably mounted inside the opening, a rectangular frame rotatably mounted at the end of the rotating block away from the opening, and a drive roller and a cleaning roller rotatably mounted inside the rectangular frame.

[0015] Optionally, two rotating frames are rotatably installed at the end of the rectangular frame away from the rotating block. Each of the two rotating frames has a rectangular plate inside. Two third sliding grooves are opened on the inner walls of both sides of the two rotating frames. A third slider is installed inside each of the two third sliding grooves. The outer walls of both sides of the two rectangular plates are connected to the two adjacent third sliders.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, the air cleaning mechanism can automatically clean the double-sided metal film with high-purity air before it is wound into shape, removing excess material during the winding process, ensuring the quality and pass rate of the double-sided metal film, facilitating better winding of capacitor components, and also ensuring that the service life and reliability of the capacitors produced are improved.

[0018] 2. In this invention, after the capacitor component, which is wound and formed on the outer wall of the telescopic end of a set of support rods, rotates to the bottom of the rotating frame, the two first sliders can be controlled to move the moving plate, the arc plate, and the clamping plate upward together to the same height as the capacitor component waiting to be unloaded. The two electric telescopic rods are controlled to move the two clamping plates to clamp and fix the capacitor component. After the telescopic ends of the set of support rods are all retracted, the capacitor component can be clamped and limited by the two clamping plates. The two first sliders are controlled to move downward and reset, so that the capacitor component located between the two clamping plates falls smoothly onto the top of the guide plate and is flexibly placed, ensuring the safety of the unloading of the wound capacitor component.

[0019] 3. In this invention, before the capacitor component is clamped and dropped to the top of the guide plate by means of two clamping plates and other components, the capacitor component is moved downward to a position on the same straight line as the industrial camera. The industrial camera can identify and detect one end of the capacitor component, and the two electric telescopic rods drive the two clamping plates and the clamped and fixed capacitor component to rotate 180 degrees together, so that the industrial camera can continue to identify and detect the other end of the capacitor component to detect whether the double-sided metal film wound capacitor component is tight.

[0020] 4. In this invention, if the industrial camera detects that the tightness of the capacitor component winding does not meet the requirements, the guide plate can be controlled to rotate counterclockwise downward between the two second sliders. This allows the defective capacitor component placed at the top of the guide plate to fall through the slot from the back of the vertical plate into the preset collection container for collection. If the tightness of the capacitor component winding meets the requirements, the guide plate can be controlled to rotate clockwise downward between the two second sliders. At this time, the qualified capacitor component at the top of the guide plate will slowly slide from the top of the guide plate into the auxiliary unloading mechanism for flexible unloading, thereby further improving the safety of unloading qualified capacitor components.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-12 An automatic winding machine for double-sided metal film for capacitors includes a base plate 1 and a vertical plate 2. The vertical plate 2 is mounted on the top of the base plate 1. A rotating frame 4 is rotatably mounted on the front of the vertical plate 2. Multiple winding mechanisms for winding and forming capacitors are installed inside the rotating frame 4. Two fixed frames 6 are mounted on the front of the vertical plate 2. An air cleaning mechanism for cleaning both sides of the double-sided metal film is provided on the outer wall of the side of the two fixed frames 6 that are close to each other. A clamping mechanism for assisting in unloading the wound capacitors is mounted on the front of the vertical plate 2. A fixed plate 3 is mounted on the front of the vertical plate 2 and directly below the rotating frame 4. A guiding mechanism for guiding the unloading of capacitors is provided on the top of the fixed plate 3. An auxiliary unloading mechanism for continuously unloading qualified capacitors is provided at the end of the fixed plate 3 away from the vertical plate 2.

[0037] As a technical optimization of the present invention, a first motor 15 is installed on the back of the vertical plate 2, and the output end of the first motor 15 is connected to the rotating part of the rotating frame 4. By starting the first motor 15, the rotating frame 4 and its internal multiple winding mechanisms can be driven to rotate and adjust.

[0038] As a technical optimization of the present invention, two conveying rollers 5 are rotatably mounted on the front of the vertical plate 2 and above the two fixed frames 6. Mounting frames 7 are rotatably mounted on the bottom of each of the two fixed frames 6, and limiting rollers 8 for limiting and supporting the capacitors during the winding process are mounted on the bottom of each mounting frame 7. The two conveying rollers 5 can guide and convey the double-sided metal film, preventing deviations in the double-sided metal film when it is conveyed into the rotating frame 4. A first driving device is preset on one outer wall of each of the two fixed frames 6. The output ends of the two first driving devices are respectively connected to the rotating parts of one end of each of the two mounting frames 7, thereby driving the two mounting frames 7 to rotate and adjust the limiting rollers 8 inside the corresponding fixed frames 6.

[0039] As a technical optimization of the present invention, the winding mechanism includes multiple telescopic support rods 20 rotatably mounted on the inner walls of both sides of the rotating frame 4. Multiple second motors 19 are mounted on the outer wall of the rotating frame 4 near the vertical plate 2, and the output ends of the multiple second motors 19 are respectively connected to the support rods 20 adjacent to them. When the telescopic ends of two support rods 20 in the same straight line position are extended, they can be in a tight abutment state. This allows one end of the double-sided metal film to be guided into the interior of the rotating frame 4 and contact the outer walls of the telescopic ends of two of the support rods 20. As the second motor 19 drives the corresponding support rod 20 to rotate, it can also drive the other support rod 20, which is in close abutment with its telescopic end, to rotate synchronously. During this rotation, the two support rods 20 can wind the double-sided metal film until it is wound to a specified size. Then, the rotating frame 4 is controlled to rotate 90 degrees clockwise downwards, causing the two support rods 20 of the other winding mechanism to rotate directly below the double-sided metal film, thus achieving continuous winding and forming of the capacitor.

[0040] As a technical optimization of the present invention, the air cleaning mechanism includes two connecting rods 21 installed on the outer wall of two fixed frames 6 on one side close to each other. An air outlet 22 is installed at the end of each connecting rod 21 away from the fixed frame 6. Both air outlets 22 are connected to a pre-set air outlet device through pipes 23 provided on the outer wall. An air outlet device is pre-set inside the machine body. After the air outlet device is activated, the high-purity air generated inside is discharged through the two pipes 23 to both sides of the double-sided metal film via the two air outlets 22, automatically cleaning both sides of the double-sided metal film to be wound, removing excess material during the winding process, and ensuring the quality and pass rate of the double-sided metal film.

[0041] As a technical optimization of the present invention, the clamping mechanism includes two first sliding grooves 16 opened on the front of the vertical plate 2. A first slider 24 is installed inside each of the two first sliding grooves 16. A movable plate 9 is installed at the end of each first slider 24 away from the first sliding groove 16. An arc-shaped plate 25 is installed on the outer wall of the side of the two movable plates 9 that are close to each other. A first linear motor is preset inside each of the two first sliding grooves 16. The two first linear motors can drive the two first sliders 24 to move up and down inside the corresponding first sliding grooves 16, thereby causing the two movable plates 9 and the arc-shaped plates 25 to move up and down together on the front of the vertical plate 2.

[0042] As a technical optimization of the present invention, arc-shaped grooves 26 are formed on the outer walls of the two arc-shaped plates 25 that are close to each other. Electric sliders 27 are installed inside the two arc-shaped grooves 26. The outer walls of the two electric sliders 27 that are close to each other are connected to clamping plates 29 through electric telescopic rods 28. The two electric sliders 27 can move inside the corresponding arc-shaped grooves 26, thereby driving the two electric telescopic rods 28 and clamping plates 29 to move and adjust synchronously.

[0043] As a technical optimization of the present invention, the guiding mechanism includes two vertical rods 10 mounted on the top of the fixed plate 3. A second sliding groove 30 is formed on the outer wall of the two vertical rods 10 on their adjacent sides. A second slider 31 is installed inside each of the two second sliding grooves 30. A guide plate 32 is rotatably mounted on the ends of the two second sliders 31 away from the second sliding grooves 30. A through groove 14 is formed inside the vertical plate 2 for adjusting the rotation of one end of the guide plate 32. An industrial camera 17 is mounted on the front of the vertical plate 2 near the guide plate 32. A second linear motor is pre-installed inside each of the two second sliding grooves 30. The two second linear motors can drive the two second sliders 31 to move up and down inside the corresponding second sliding grooves 30, thereby driving the guide plate 32 to move up and down between the two vertical rods 10. A second driving device is pre-installed inside one of the second sliders 31. The output end of the second driving device is connected to the rotating part at the bottom end of the guide plate 32, thereby enabling the guide plate 32 to rotate between the two second sliders 31.

[0044] As a technical optimization of the present invention, the auxiliary feeding mechanism includes an opening 18 at the end of the fixed plate 3 away from the vertical plate 2. A rotating block 33 is rotatably mounted inside the opening 18. A rectangular frame 11 is rotatably mounted at the end of the rotating block 33 away from the opening 18. A drive roller 34 and a cleaning roller 35 are rotatably mounted inside the rectangular frame 11. A third driving device is preset inside the fixed plate 3. The output end of the third driving device is connected to the rotating part at one end of the rotating block 33, thereby driving the rotating block 33 to rotate and adjust inside the opening 18. A fourth driving device is preset inside the rotating block 33. The output end of the fourth driving device is connected to the rotating part at one end of the rectangular frame 11, thereby driving the rectangular frame 11 to rotate and adjust. A fifth driving device is preset inside the rectangular frame 11. The output end of the fifth driving device is connected to the rotating part at one end of the drive roller 34, thereby driving the drive roller 34 to rotate and adjust inside the rectangular frame 11.

[0045] As a technical optimization of the present invention, two rotating frames 12 are rotatably installed at the end of the rectangular frame 11 away from the rotating block 33. Each of the two rotating frames 12 has a rectangular plate 13 inside. Two third sliding grooves 36 are formed on the inner walls of both sides of each rotating frame 12. A third slider 37 is installed inside each of the two third sliding grooves 36. The outer walls of both sides of the two rectangular plates 13 are connected to the two adjacent third sliders 37. Two driving devices are preset on one outer wall of the rectangular frame 11. The output ends of the two driving devices are respectively connected to the rotating parts at one end of the corresponding rotating frame 12, thereby enabling the two rotating frames 12 to rotate and adjust on the upper and lower sides of one end of the rectangular frame 11. A third linear motor is preset inside the third sliding groove 36. The third linear motor can drive the third slider 37 to move and adjust within the corresponding third sliding groove 36, thereby synchronously moving and adjusting the corresponding rectangular plate 13 within the rotating frame 12.

[0046] In this invention, when the user uses the device, one end of the double-sided metal film is guided and transported between two conveying rollers 5 by multiple guide rollers on the winding machine. The film continues to be transported towards the rotating frame 4 below by the rotation of the two conveying rollers 5. When one end of the double-sided metal film is about to move close to one of the support rods 20, the telescopic ends of the two support rods 20 are extended together. After one end of the double-sided metal film abuts against the outer wall of the telescopic ends of the two support rods 20, the corresponding second motor 19 drives one support rod 20 to rotate, simultaneously driving the other support rod 20 that abuts against the telescopic end of one of the support rods 20 to rotate synchronously. The double-sided metal film automatically winds up as the two support rods 20 rotate. A cylindrical capacitor component, after being wound into shape, can be controlled by the first motor 15 to drive the rotating frame 4 to rotate 90 degrees clockwise. The double-sided metal film is cut by the cutting device preset on the right side of the rotating frame 4. At this time, the second set of support rods 20 rotates to be close to the two conveying rollers 5 directly below, and continues to carry out the relevant winding work. After the capacitor component at the telescopic end of the second set of support rods 20 is wound into shape, the rotating frame 4 is controlled to rotate 90 degrees clockwise downward. At this time, the first wound capacitor component rotates to the bottom end, and as the telescopic end of the first set of support rods 20 contracts, the capacitor loses its internal support and falls downward to the top of the guide plate 32, thus completing the entire capacitor winding and forming process.

[0047] Because an air cleaning mechanism is installed below the two conveying rollers 5, and an air outlet device is pre-installed inside the machine body, after the air outlet device is started, the high-purity air generated inside is discharged to both sides of the double-sided metal film through two air outlets 22 via two pipes 23, automatically cleaning both sides of the double-sided metal film to be wound, removing excess material during the winding process of the double-sided metal film, ensuring the quality and pass rate of the double-sided metal film, and facilitating better subsequent winding and forming of capacitor components.

[0048] Furthermore, clamping mechanisms are provided on both sides of the rotating frame 4. To prevent the wound capacitor component from directly contacting the top of the guide plate 32 rigidly when it is automatically dropped downwards, which could cause damage to the surface of the capacitor component, the capacitor component wound on the outer wall of the telescopic end of a set of support rods 20 can be rotated to the bottom of the rotating frame 4. At this time, the two first sliders 24 can be controlled to move the moving plate 9, the arc plate 25 and the clamping plate 29 upwards together to the same height as the capacitor component waiting to be dropped, inside the corresponding first slide groove 16. The telescopic ends of the two electric telescopic rods 28 can be extended together, so that the two clamping plates 29 can clamp and fix the capacitor component. After the telescopic ends of the set of support rods 20 are retracted, the capacitor component can be clamped and limited by the two clamping plates 29. The two first sliders 24 can be controlled to move downwards and reset inside the corresponding first slide groove 16, so that the capacitor component located between the two clamping plates 29 can be flexibly placed on the top of the guide plate 32, ensuring the safety of the wound capacitor component dropping.

[0049] Meanwhile, before the capacitor component is clamped and dropped to the top of the guide plate 32 using the two clamping plates 29 and other components, the capacitor component moves downward to a position on the same straight line as the industrial camera 17 (e.g., Figure 2 and Figure 12 As shown, with the help of an industrial camera 17, one end of the capacitor component can be identified and detected. With the help of two electric telescopic rods 28, the two clamping plates 29 and the capacitor component that is clamped and fixed can be rotated 180 degrees together, so that the industrial camera 17 can continue to identify and detect the other end of the capacitor component to detect whether the capacitor component formed by the double-sided metal film is tight.

[0050] If the industrial camera 17 detects that the tightness of the capacitor component winding does not meet the requirements, the two second sliders 31 can be controlled to move downward to a specified height inside the corresponding second slide grooves 30. Then, the guide plate 32 can be controlled to rotate counterclockwise downward between the two second sliders 31, so that the defective capacitor component placed on top of the guide plate 32 will fall through the through groove 14 from the back of the vertical plate 2 into the preset collection container for collection. If the tightness of the capacitor component winding meets the requirements, the rotating block 33 can be controlled to slowly rotate downward inside the opening 18. At the same time, the rotating frame 12 at the bottom of the rectangular frame 11 can be controlled to rotate adaptively towards the rotating block 33 to ensure that the bottom end of the lower rotating frame 12 can always be in contact with the ground when the rectangular frame 11 is rotated downward, providing auxiliary support for the rectangular frame 11. Then, the two second sliders 31 can be controlled to move downward to a suitable height inside the corresponding second slide groove 30. The guide plate 32 is then controlled to rotate clockwise downward between the two second sliders 31. At this time, the qualified capacitor components located at the top of the guide plate 32 will slowly slide from the top of the guide plate 32 to the top of the drive roller 34 and the cleaning roller 35. After a sufficient number of qualified capacitor components are placed on the top of the drive roller 34 and the cleaning roller 35, the drive roller 34 can be controlled to rotate slowly inside the rectangular frame 11, thereby driving multiple capacitor components located at the top of the drive roller 34 to rotate together. At this time, multiple capacitor components will rub against the outer wall of the cleaning roller 35 during the rotation, so that a small amount of impurities attached to the surface of the capacitor components can be automatically removed, which is convenient for further processing of qualified capacitor components.

[0051] After the drive roller 34 and cleaning roller 35 automatically clean the surfaces of multiple capacitor components, the rotating frame 12 located at the top of the rectangular frame 11 can be controlled to rotate downwards by 90 degrees to a horizontal position. Simultaneously with the downward rotation of the rotating frame 12, multiple third sliders 37 inside it are controlled to move and adjust within their corresponding third grooves 36, causing the rectangular plate 13 to move and adjust synchronously. After the rotating frame 12 reaches a horizontal position, the multiple third sliders 37 are then controlled to slowly move the rectangular plate 13 downwards, ensuring that the bottom of the rectangular plate 13 can clean the capacitors placed on top of the drive roller 34 and cleaning roller 35. The component is pressed to the limit position, and then the rectangular frame 11 can rotate 180 degrees to adjust, driving the multiple capacitor components on the top of the drive roller 34 and cleaning roller 35 to rotate to the bottom of the rectangular frame 11. At this time, the rotating frame 12, which has rotated to the bottom, is controlled to slowly rotate downwards at a certain angle. The multiple capacitor components can then slide outwards from the top of the rectangular plate 13 and be fed into the preset collection container in sequence, completing the classification and feeding of qualified and unqualified capacitor components, as well as the further flexible feeding of qualified capacitor components, thereby further improving the safety of the feeding process of qualified capacitor components.

[0052] Moreover, after the rectangular frame 11 is rotated 180 degrees, it rotates multiple capacitor components that were originally located at the top of the drive roller 34 and the cleaning roller 35 to the bottom. While the multiple capacitor components are being slowly fed, the top of the drive roller 34 and the cleaning roller 35 can continue to perform related cleaning and temporary storage work on the capacitor components, so that the feeding of qualified capacitor components is continuous, thereby improving the feeding efficiency of qualified capacitor components.

[0053] While using the industrial camera 17 to inspect the tightness of the capacitor component, before the two clamping plates 29 assist in the flexible unloading of the capacitor component, the telescopic ends of the two electric telescopic rods 28 extend together, causing the two clamping plates 29 to clamp and fix the capacitor component. Then, one electric slider 27 is controlled to move upward inside the corresponding arc groove 26, and the other electric slider 27 is controlled to move downward inside the corresponding arc groove 26. This allows the two clamping plates 29 to twist the wound capacitor component through mechanical inspection, thereby further inspecting the tightness of the capacitor component and improving the accuracy of the tightness inspection. Moreover, this method of inspecting the tightness of the capacitor component can be a sampling inspection, avoiding the impact on the overall winding efficiency of the capacitor component.

[0054] If some capacitor components need to be directly extruded into a flat shape after being wound, they can be rotated to the bottom of the rotating frame 4. The telescopic ends of the two electric telescopic rods 28 can then extend together, driving the two clamping plates 29 to directly extrude the hollow capacitor components. Then, with the cooperation of the two clamping plates 29 and other components, they can be flexibly placed on top of the guide plate 32. At this point, they can be... Figure 2 As shown, the two rectangular plates 13 are controlled to move and adjust inside the corresponding rotating frame 12, ensuring that both rectangular plates 13 move to a position close to the rectangular frame 11. Then, with the help of the rotating block 33, the rectangular frame 11 is rotated downward together. After the capacitor component is flattened and inspected at the top of the guide plate 32, the qualified capacitor component can fall into the rotating frame 12 located above. With the help of the rectangular plate 13 inside, it is guided outward and discharged into the preset collection container. This allows the auxiliary feeding mechanism to guide and flexibly feed the flattened capacitor component, improving the applicability of the auxiliary feeding mechanism in actual use.

[0055] This automatic winding machine is highly integrated and can perform thorough cleaning, adjustment, and inspection of capacitor components before and after winding, making it highly practical and efficient in application.
