Abstract

An automatic film-applying and film-removing mechanism for a coil includes a film storage mechanism, a material suction and clamping mechanism, a winding mechanism, and a pressure roller mechanism. The film storage mechanism has multiple films for attaching to the coil, each film including a base film and an outer film. The material suction and clamping mechanism picks up and moves the film, attaching the outer film to the coil. The winding mechanism sets the coil and drives it to rotate. The pressure roller mechanism includes a two-axis moving assembly and a pressure roller assembly. The pressure roller presses the film onto the coil, while the winding mechanism drives the coil to rotate, wrapping the film around the coil, thus achieving film application. During film removal, after the material suction and clamping mechanism clamps the base film, the winding mechanism drives the coil to rotate in the opposite direction of the film winding direction, thereby tearing off the coiled base film while the outer film remains attached to the coil, achieving automatic film removal.

Description

Technical Field

[0001] This invention relates to the field of coil film application and removal devices, and particularly to an automatic film application and removal mechanism for coils. Background Technology

[0002] A coil typically refers to a loop of wire winding. Common applications include motors, inductors, transformers, and loop antennas. It is generally made by winding individual wires together, with the wires insulated from each other. Some coils require a film to be wrapped around them after winding to secure the wires, necessitating an automatic film-applying device. Existing automatic film-applying devices include the automatic coil film-applying equipment disclosed in patent number CN201921610786.3. This equipment includes a machine base 1, a film-applying gripping mechanism 2, a film waste removal mechanism 3, an automatic film-applying mechanism 4, a film-pressing mechanism 5, a coding mechanism 6, a qualified product discharge mechanism 7, a fixture rotation mechanism 8, and a fixture 9. During film application, the automatic film-applying mechanism 4 raises the film to the top opening of the storage bin, and then the three-axis robotic arm 21 of the film-applying gripping mechanism 2 drives the film-applying suction cup 22 to pick up the film. Then, the rotary cylinder 31 of the film-applying waste stripping mechanism 3 drives the waste suction cup 32 to rotate above the film-applying waste, sucking up the waste film. The film-applying suction cup 22 can then tear and peel the film off from the waste film. Finally, the three-axis robot 21 attaches the film to the coil.

[0003] Existing film-applying devices typically peel off the film first and then apply it to the coil. This is because the film wraps around the coil in layers, making it difficult to peel off directly. However, this adds an extra step and device specifically for peeling off the film. Furthermore, due to the adhesive nature of the film, peeling off the base film first makes it difficult for the three-axis robotic arm to grasp the film. Summary of the Invention

[0004] In view of this, the present invention provides an automatic film application and removal mechanism for coils to solve the above-mentioned technical problems.

[0005] An automatic film-applying and film-removing mechanism for a coil. The mechanism includes a film storage mechanism, a material suction and clamping mechanism, a winding mechanism, and a pressure roller mechanism. The film storage mechanism has multiple films for attaching to the coil. Each film includes a base film and an adhesive film disposed on the base film. The material suction and clamping mechanism picks up and moves the film, attaching the film to the coil. The winding mechanism sets the coil and rotates it. The pressure roller mechanism includes a two-axis moving assembly and at least one pressure roller assembly disposed on the two-axis moving assembly. Each pressure roller assembly includes a mounting plate disposed on the two-axis moving assembly, a second slide rail disposed on the mounting plate, an L-shaped mounting plate slidably disposed on the second slide rail, a film-pressing roller rotatably disposed on the L-shaped mounting plate, and two second springs disposed between the L-shaped mounting plate and the mounting plate. The central axis of the film-pressing roller is parallel to the central axis of the rotating assembly. The pressure roller presses the film onto the coil, while the winding mechanism drives the coil to rotate so that the film wraps around the coil, thus achieving film application. During film removal, the material suction and clamping mechanism holds the base film, and the winding mechanism drives the coil to rotate in the opposite direction to the film winding direction, thus achieving film removal.

[0006] Furthermore, the size of the bottom film is larger than the size of the adhesive film, and the bottom film will have a section without the adhesive film for the material suction and clamping mechanism to hold.

[0007] Furthermore, the material suction and clamping mechanism includes a three-axis moving device, a rotating device disposed on the three-axis moving device, a rotating plate disposed on the rotating device, at least one suction nozzle assembly disposed on the rotating plate, and at least one gripper cylinder disposed on the three-axis moving device. One end of the rotating plate is disposed on the rotating device, and the other end is disposed on the suction nozzle assembly.

[0008] Furthermore, the suction nozzle assembly includes a first slide rail disposed on the rotating plate, a suction nozzle slidably disposed on the first slide rail, a limiting plate disposed on the rotating plate, and a first spring disposed between the limiting plate and the suction nozzle. The limiting plate is located at one end of the first slide rail, and the first spring pushes the suction nozzle to slide on the first slide rail by its own elastic force.

[0009] Furthermore, the detection and correction mechanism includes a pneumatic gripper cylinder, two correction blocks disposed in the pneumatic gripper cylinder, and a camera detection device.

[0010] Furthermore, the two output ends of the pneumatic gripper cylinder are respectively provided with the correction blocks and used to drive them to move closer or further apart. The opposing side of the correction blocks is provided with a correction groove. The pneumatic gripper cylinder drives the two correction blocks to move closer to each other and clamp the diaphragm to adjust and correct its direction.

[0011] Furthermore, the winding mechanism includes a winding bracket and a rotating assembly disposed on the winding bracket, the winding bracket having a U-shaped structure.

[0012] Furthermore, the L-shaped mounting plate can slide along the second slide rail and the sliding direction is close to or away from the winding mechanism. The second spring will push the L-shaped mounting plate to slide on the second slide rail by its own elastic force. When the pressure roller mechanism presses the diaphragm on the coil, the second spring is compressed.

[0013] Furthermore, the edge of the pressing wheel is provided with a rubber edging.

[0014] Compared with existing technologies, the automatic film application and removal mechanism for coils provided by this invention allows the winding mechanism to drive the coil to rotate forward or backward. The pressure roller presses the film onto the coil, while the winding mechanism drives the coil to rotate, cooperating with the pressure roller to wrap the film around the coil, thus achieving automatic film application. When film removal is required, because the size of the base film is larger than the size of the film, a section of the base film without the film is left for the gripper cylinder to hold. After the gripper cylinder holds the film, the winding mechanism drives the coil to rotate in the opposite direction to the film winding direction, thereby tearing off the base film that was originally wrapped around the coil, while the film remains attached to the coil, achieving automatic film removal.

[0021] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0022] like Figures 1 to 6 The diagram shown is a structural schematic of the automatic film application and removal mechanism for the coil provided by the present invention. The automatic film application and removal mechanism for the coil includes a film storage mechanism 10, a material suction and clamping mechanism 20, a detection and correction mechanism 30, a winding mechanism 40, and a pressure roller mechanism 50. It is conceivable that the automatic film application and removal mechanism for the coil also includes other functional modules, such as connecting components, sensors, and mounting components, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0023] The diaphragm storage mechanism 10 is located below the suction and clamping mechanism 20. The diaphragm storage mechanism 10 is provided with multiple diaphragms 11 for attaching to the coil 100. The diaphragm storage mechanism 10 is used to feed the diaphragms 11; this is prior art and will not be described in detail here. Each diaphragm 11 includes a base film 12 and an adhesive film 13 disposed on the base film 12. The base film 12 is a transparent plastic base film used to support the adhesive adhesive film 13. The size of the base film 12 is larger than the size of the adhesive film 13. The adhesive film 13 is adhesive and is used to attach to the coil 100. The diaphragm 11 is prior art and will not be described in detail here.

[0024] The material suction and clamping mechanism 20 includes a three-axis moving device 21, a rotating device 22 disposed on the three-axis moving device 21, a rotating plate 23 disposed on the rotating device 22, at least one suction nozzle assembly 24 disposed on the rotating plate 23, and at least one gripper cylinder 25 disposed on the three-axis moving device 21.

[0025] The three-axis moving device 21 is used to drive the suction nozzle assembly 24 and the gripper cylinder 25 to move along three axes, so that they can be moved to different workstations to perform suction or gripping operations. The three-axis moving device 21 should be existing technology and will not be described in detail.

[0026] The rotating device 22 is a rotary motor or similar device. One end of the rotating plate 23 is mounted on the rotating device 22, and the other end is equipped with the suction nozzle assembly 24. The rotating device 22 can drive the rotating plate 23 to rotate, thereby driving the suction nozzle assembly 24 at the other end of the rotating plate 23 to rotate, thus changing the orientation of the suction nozzle assembly 24 so that it faces the membrane storage mechanism 10 to pick up the membrane 11. After passing through the detection and correction mechanism 30, it rotates again to face the winding mechanism 40 to attach the membrane 11 to the coil 100. The suction nozzle assembly 24 includes a first slide rail 241 mounted on the rotating plate 23, a suction nozzle 242 slidably mounted on the first slide rail 241, a limiting plate 243 mounted on the rotating plate 23, and a first spring 244 mounted between the limiting plate 243 and the suction nozzle 242.

[0027] The suction nozzle 242 is slidably mounted on the first slide rail 241 via sliding support components such as a slider. The suction nozzle 242 is connected to an external air pump via an air tube, enabling it to suction air to hold the diaphragm 11. The limiting plate 243 is located at one end of the first slide rail 241. The first spring 244, through its own elasticity, pushes the suction nozzle 242 to slide on the first slide rail 241. When the three-axis moving device 21 drives the suction nozzle 242 to press down and suck up the diaphragm 11, the first spring 244 is compressed, and the suction nozzle 242 retracts, thus providing a buffering effect. The gripper cylinder 25 faces the winding mechanism 40 and is used to grip and peel off the base film 12 after the film application is completed. A detailed explanation will follow in conjunction with the pressure roller mechanism 50.

[0028] The detection and correction mechanism 30 includes a pneumatic gripper cylinder 31, two correction blocks 32 disposed on the pneumatic gripper cylinder 31, and a camera detection device 33.

[0029] The two output ends of the pneumatic gripper cylinder 31 are respectively provided with the correction blocks 32, which are used to move them closer or further apart. A correction groove 34 is provided on the opposite side of each correction block 32. After the suction nozzle 242 picks up the diaphragm 11 on the diaphragm storage mechanism 10, it moves between the two correction blocks 32. The pneumatic gripper cylinder 31 drives the two correction blocks 32 to move closer together, thereby clamping the diaphragm 11 and adjusting its orientation. Then it moves above the camera detection device 33, which is used to photograph and detect the corrected diaphragm 11 to check its position. It is also used to identify the position of the film 13 so that the film 13 can be attached to the coil 100. The camera detection device 33 is existing technology and will not be described in detail here.

[0030] The winding mechanism 40 is used to set the coil 100 and cooperate with the external guide pin to wind the wire onto the coil 100. The winding mechanism 40 includes a winding support 41 and a rotating component 42 disposed on the winding support 41. The winding support 41 has a U-shaped structure, and the winding component 42 is used to set the coil 100 and drive it to rotate. In this embodiment, the coil 100 has a strip-shaped structure and the wire is wound onto the coil 100 by the winding mechanism 40. The winding mechanism 40 should be prior art and will not be described in detail here.

[0031] The pressure roller mechanism 50 includes a two-axis moving assembly 51 and at least one pressure roller assembly 52 disposed on the two-axis moving assembly 51.

[0032] The two-axis moving assembly 51 is used to drive the pressure roller assembly 52 to move, so that the pressure roller assembly 53 is in contact with or away from the coil 100. The pressure roller assembly 52 includes a mounting plate 521 disposed on the two-axis moving assembly 51, a second slide rail 522 disposed on the mounting plate 521, an L-shaped mounting plate 523 slidably disposed on the second slide rail 522, a pressing roller 524 rotatably disposed on the L-shaped mounting plate 523, and two second springs 525 disposed between the L-shaped mounting plate 523 and the mounting plate 521.

[0033] The mounting plate 521 has an L-shaped structure. The L-shaped mounting plate 523 can slide along the second slide rail 522, with the sliding direction approaching or moving away from the winding mechanism 40, thereby causing the pressure roller 524 to adhere to or move away from the coil 100. The edge of the pressure roller 524 is provided with a rubber edging to prevent damage to the coil 100. The central axis of the pressure roller 524 is parallel to the central axis of the rotating assembly 42, so that the pressure roller 524 can press against the side of the coil 100. The second spring 525 pushes the L-shaped mounting plate 523 to slide on the second slide rail 522 by its own elastic force. Therefore, when the pressure roller mechanism 50 presses against the diaphragm 11 on the coil 100 under the drive of the two-axis moving assembly 51, the second spring 525 will be compressed, and the pressure roller 524 will retract, thereby providing a cushioning effect.

[0034] When film application is required after the winding mechanism 40 has completed winding, the rotating device 22 drives the rotating plate 23 to rotate, causing the suction nozzle assembly 24 to face the film storage mechanism 10 to pick up the film 11. After being corrected and detected by the detection and correction mechanism 30, it rotates again to face the winding mechanism 40 to adhere the film 11 to the coil 100. Then, the two-axis moving assembly 51 drives the pressure roller assembly 52 to move, and the pressure roller 524 presses the film 11 to adhere the film 13 to the coil 100. At the same time, the winding mechanism 40 drives the coil 100 to rotate and, in conjunction with the pressure of the pressure roller 524, wraps the film 11 around the coil 100, thereby achieving automatic film application. When it is necessary to peel off the film, since the size of the bottom film 12 is larger than the size of the adhesive film 13, a section of the bottom film 12 without the adhesive film 13 will be left for the gripper cylinder 25 to hold. After the gripper cylinder 25 holds the film, the winding mechanism 40 drives the coil 100 to rotate in the opposite direction to the winding direction of the film 11, thereby peeling off the bottom film 12 that was originally wrapped around the coil 100, while the adhesive film 13 remains stuck to the coil 100, thus realizing automatic film peeling.

[0035] Compared with the prior art, the winding mechanism 40 of the automatic film application and removal mechanism for coils provided by the present invention can drive the coil 100 to rotate forward or backward. The pressure roller 524 presses the film 11 to adhere the film 13 to the coil. At the same time, the winding mechanism 40 drives the coil to rotate and, in conjunction with the pressure roller 524, wraps the film 11 around the coil, thereby achieving automatic film application. When film removal is required, since the size of the bottom film 12 is larger than the size of the film 13, a section of the bottom film 12 without the film 13 is left for the gripper cylinder 25 to hold. After the gripper cylinder 25 holds the film, the winding mechanism 40 drives the coil to rotate in the opposite direction to the winding direction of the film 11, thereby tearing off the bottom film 12 that was originally wrapped around the coil, while the film 13 remains adhered to the coil, achieving automatic film removal.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
