Description

Technical Field

[0001] This invention relates to the field of automated assembly, and more specifically, to an automated film wrapping device and method for the outer surface of a cylindrical component. Background Technology

[0002] In large-scale industrial manufacturing and assembly, as well as in certain specific fields, particularly for cylindrical components requiring electrical operation (such as shafts and cylindrical parts), thin-film winding technology is commonly used. However, subsequent processing of the film requires a reaction with the cylindrical component to achieve the desired physical properties. Existing adhesive tapes, once bonded to the film, adhere tightly, making subsequent removal extremely difficult. This often necessitates damaging the film for complete removal, or leaving tape residue on the film surface, affecting subsequent processing of the cylindrical component.

[0003] In existing wrapping devices, the subsequent unpacking process is often very troublesome after the tape is wrapped. The tape is in complete contact with the surface of the item, making it difficult to locate the starting point of the tape. Often, the film needs to be damaged to remove the tape. Furthermore, existing devices typically use rollers and swing arms to hold the tape in place during application, which can cause the adhesive side of the tape to deflect during application, affecting subsequent application. For example, the packaging film fixing device for a wrapping robot disclosed in patent application number 202110490938.6 still has shortcomings in tape application. During operation, due to roller control issues, the adhesive side of the tape deflects during application, affecting the bonding effect and product quality. Additionally, after the tape is applied, the subsequent unpacking process is very troublesome because the tape is completely adhered to the film, making it difficult to locate the starting point of the tape, and some tape remains on the film surface.

[0015] A film-pressing assembly that ensures the film adheres tightly to the surface of the cylindrical component during winding;

[0016] A cutter installed on the upper film assembly to cut the film after it has been wrapped.

[0017] Preferably, the film wrapping assembly includes: a mounting plate with an inner annular guide rail, a connector with an arc-shaped structure slidably disposed on the annular guide rail, a film roll disposed on the side wall of the connector, and a drive motor disposed inside the mounting plate;

[0018] The connector has a rack on its outer side wall, the output end of the drive motor meshes with the rack, and the mounting plate and connector have notches with the same size as the connecting arm of the pneumatic gripper.

[0019] Preferably, the upper film assembly includes: an inverted L-shaped structural member, the structural member being in contact with the film of the wrapping assembly via a three-degree-of-freedom driving component II, a film clamping cylinder being provided on the side wall of the structural member, and a pressure block being provided on the output end of the film clamping cylinder that matches the spatial position of the extension of the structural member, the pressure block being driven by the film clamping cylinder to abut against the surface of the structural member to form a clamping station for clamping the film;

[0020] The bottom of the pressure block is connected to the output end of the clamping cylinder via multiple springs. When the springs are not compressed, the height of the cutter is lower than the height of the pressure block. The cutter is located at the output end of the clamping cylinder and on the outside of the structural component.

[0021] Preferably, the pressure film assembly is a pressure film sheet, which, through a two-degree-of-freedom driving component III located at the bottom, ensures that the thin film is in close contact with the outer surface of the cylindrical body.

[0022] Preferably, it further includes: a pressing assembly disposed between the winch and the folding mechanism for rolling the adhesive tape, the pressing assembly including: rolling rollers disposed at both ends of the surface of the mounting groove and cooperating with the adhesive tape;

Driven by the driving component III, the film pressing sheet abuts against the surface of the cylindrical component, the pressure block is released, and the upper film assembly moves to the initial position.

[0028] The film wrapping assembly wraps multiple turns of film around the surface of the cylindrical body. After the film wrapping is completed, the pressure sheet abuts against the surface of the cylindrical body again, and the film loading assembly moves to the film cutting position again. The cutter cuts the wrapped film under the drive of the film clamping cylinder.

[0029] The adhesive applicator's suction cup I adsorbs the tape before it is pasted, and forms a tape head on the tape through the folding component. Driven by the drive component I, it moves to the joint of the film break. With the cooperation of the drive component I and the roller, the outer adhesive side of the tape adheres to the film. At the same time, suction cup I stops adsorbing, and the tape is stretched and pasted. After the pasting is completed, suction cups I and II adsorb the tape. Finally, the cutting component cuts the adsorbed and fixed tape to complete the pasting.

[0030] The present invention has at least the following beneficial effects: by setting the folding component, the tape head is formed before the tape is pasted, which facilitates the subsequent processing of the tape on the film and avoids damage to the tape, thereby avoiding damage to the surface of the cylindrical part. At the same time, the adsorption component ensures that the tape does not shake during the initial pasting and cutting, thus ensuring the efficiency of the tape pasting work.

[0052] Figure 1 An automatic film-wrapping device for the outer surface of a cylindrical component according to the present invention is shown, comprising: a hoisting mechanism 1 for fixing and moving the cylindrical component 4 in space; a film-applying mechanism 2 for wrapping a film around a portion of the cylindrical component 4 on the hoisting mechanism 1; and an adhesive-applying mechanism 3 for fixing adhesive tape onto the cylindrical body after the film is wrapped. The adhesive-applying mechanism 3 performs adhesive application on the film on the cylindrical body through a two-degree-of-freedom driving component I 38. The adhesive-applying mechanism 3 includes: a mounting component 31 fixedly connected to the Z-axis output end of the driving component I 38.

[0053] A winch 32 for holding tape is provided on one side extension of the mounting component 31;

[0054] The other side of the mounting component 31 has a mounting groove in space, and a folding component 33 is arranged between the mounting grooves. The folding component 33 folds the starting end of the tape under the drive of the folding motor to obtain a tape head that is easy to tear.

[0055] An adsorption assembly 34 is set upstream and downstream of the folding assembly 33 to fix the tape before pasting and during cutting.

[0056] A cutting component 39 is placed between the adsorption components 34 and cuts the pasted tape.

[0057] Working principle:

[0058] The hoisting mechanism 1 moves the cylindrical component 4 to the designated position and fixes it. The film-applying mechanism 2 is activated to wrap the cylindrical component 4 with film. After the film is wrapped, the adhesive-applying mechanism 3 is activated, and the driving component I 38 moves the mounting component 31 above the cylindrical component 4. The winch 32 releases the tape, which forms a tape head after passing through the folding component 33. The adsorption component 34 fixes the starting end of the tape, and the folding component 33 and the adsorption component 34 work together to attach the tape to the cylindrical component 4. The cutting component 39 cuts the tape at an appropriate position, completing one adhesive application operation. The hoisting mechanism 1 continues to move the cylindrical component 4 forward, and the film-applying mechanism 2 and the adhesive-applying mechanism 3 wrap and glue different parts of the cylindrical component. This achieves film protection for multiple different parts of the cylindrical component 4. The present invention, through the folding component 33, forms a tape head before the tape is applied, which facilitates the subsequent processing of the tape on the film and avoids damage to the tape, thereby preventing damage to the surface of the cylindrical component 4. Meanwhile, the adsorption component 34 adsorbs the tape before pasting and during cutting, preventing the tape from shaking during the pasting process and causing the adhesive surfaces of the tape to stick together, thus improving the pasting efficiency of the device.

[0059] In the above technical solution, the adsorption component 34 includes: a suction cup I 341 disposed upstream of the folding component 33 and a suction cup II 342 disposed downstream of the folding component 33, wherein the suction cup I 341 and the suction cup II 342 are connected to an external air source through an air inlet pipe passing through the side wall of the mounting groove. In this technical solution, suction cups I 341 and II 342 have cavities 343 on the surface of the mounting groove. A perforated plate 344 embedded within each cavity 343 is provided above it. An air pipe connector communicating with the corresponding cavity 343 is provided on the side wall of the mounting groove. The cavity 343 is connected to an external air source through an air inlet pipe on the air pipe connector, so that a negative pressure is formed between suction cups I 341 and II 342. When the negative pressure is formed by suction cups I 341, the non-adhesive side of the tape adheres tightly, ensuring that the tape does not sway in the air when not being pasted. Once the tape is pasted with the film, the external air source stops working, suction cups I 341 do not adsorb the tape, and the tape is pasted normally. After pasting is completed, the external air source is activated, and suction cups I 341 and II 342 adsorb the tape, ensuring that the tape is cut and pasted flatly with the film.

[0060] In the above technical solution, the hoisting mechanism 1 includes: a fixed plate 11, on which a pair of pneumatic grippers 12 for gripping the cylindrical part 4 are provided, and a height adjustment component is provided between the fixed plate 11 and the pneumatic grippers 12.

[0061] The height adjustment component is slidably mounted on the slide rail of the fixed plate 11, and the pneumatic gripper 12 is mounted on the height adjustment component. In this technical solution, the height adjustment component includes: a connecting plate 13 for mounting the pneumatic gripper 12; a support frame 14 slidably connected to the fixed plate 11; a lifting bracket 15 disposed between the connecting plate 13 and the support frame 14; and a drive cylinder 17 disposed on the support frame 14 and connected to the free end of the lifting bracket 15. The lifting bracket 15 is an X-shaped lifting bracket formed by two connecting rods hinged in the middle. One end of the upper end of the lifting bracket 15 is hinged to the support frame 14, and the other end is hinged to a slider I sliding on the support frame 14. One end of the lower end of the lifting bracket 15 is hinged to the connecting plate 13, and the other end is hinged to a slider II 16 sliding on the connecting plate 13. The output end of the drive cylinder 17 is fixedly connected to slider I. The fixed plate 11 is provided with a drive component IV that moves the support frame 14 back and forth along the fixed plate 11.

[0062] In the above technical solution, the film-coating mechanism includes: a film-coating assembly 21 for wrapping the outer surface of the cylindrical member 4 with multiple turns of film; a film-coating assembly 22 for moving the film on the film-coating assembly 21 from the starting position to the working position; a film-pressing assembly 23 for tightly adhering the film to the surface of the cylindrical member 4 during wrapping; and a cutter 227 disposed on the film-coating assembly 22 for cutting the film after wrapping. Using this technical solution, before wrapping begins, the starting end of the film is inserted into the clamping position formed by the structural member 221 and the pressure block 224. Driven by the driving component II 222, the starting end of the film is moved to the working position. The film-pressing sheet 231, driven by the driving component III 232, tightly adheres the film to the surface of the cylindrical member 4. Simultaneously, the clamping cylinder 223 releases the pressure block 224, releasing the starting end of the film. However, under the action of the film-pressing sheet 231, the rear end of the film continues to adhere to the cylindrical member 4. Driven by the drive motor 214, the rack 215 on the connector 212 causes the connector 212 to move in a circular motion around the annular guide rail of the mounting plate 211. The film roll 213 on the connector 212 wraps the cylindrical part 4 with film. After wrapping two more times, the pressure film sheet 231 moves backward and is pulled out from the wrapped film to prevent the subsequent wrapping from being too tight and making it difficult to pull out the pressure film sheet. The connector 212 is also provided with a tensioning rod 216 that forms a certain pre-tightening force during the film pulling process to ensure that the film is wrapped. The film can be wound tightly enough around the cylindrical member 4. After winding, the pressure sheet 231 abuts against the outer surface of the film-wrapping area of ​​the cylindrical member 4 again. At the same time, the clamping position formed by the structural member 221 and the pressure block 224 presses the film to be cut. Simultaneously, the clamping cylinder 223 acts a second time, compressing the spring 225 between the clamping cylinder 223 and the pressure block 224. The cutter 227 is higher than the surface of the structural member 221, cutting the film. After cutting, the folding motor 332 on the mounting member 31 drives... Folding tab 331 forms a tape tip at suction cup I 341. Suction cup I 341, connected to an external air source via an air inlet pipe on the air connector, creates negative pressure to adsorb the tape tip. Mounting component 31, driven by driving component I 38, makes a small arc-shaped movement around the film seam on the surface of cylindrical component 4. After the adhesive surface of the tape tip contacts the film, suction cup I 341 stops adsorbing. With the cooperation of driving component I 38 and roller 35, the tape is stretched while roller 35 ensures the tape adheres tightly to the film. After pasting, negative pressure is formed at suction cup I 341 and suction cup II 342 to adsorb the tape. Simultaneously, the cutting blade of cutting component 39 cuts the tape, completing the film pasting and fixing.The pressure film 231, mounting component 31, and structural component 221 all return to their initial positions to prepare for the next wrapping. At the same time, the drive component IV drives the support frame 14 to move on the fixed plate 11, and the cylindrical component 4 moves back and forth in space under the drive of the pneumatic gripper 12. The notches on the mounting plate 211 and the connector 212 allow the connecting arm of the pneumatic gripper 12 to move multiple parts to be wrapped on the cylindrical component 4 to the wrapping station of the wrapping assembly through the mounting plate 211 and the connector 212.

[0063] It also includes a traveling roller 36 and an anti-detachment roller 37 disposed between the mounting slots to generate a certain preload on the tape during transport. The anti-detachment roller 37 is located between the two traveling rollers 36. With this technical solution, the traveling rollers 36 and the anti-detachment roller 37 are positioned inside the mounting slots, spatially forming the direction of tape movement. Simultaneously, the anti-detachment roller 37 contacts the adhesive surface of the tape, preventing the tape from detaching during application.

[0064] In the above technical solution, the upper film assembly 22 includes: an inverted L-shaped structural member 221, the structural member 221 being in contact with the film of the wrapping assembly 21 via a three-degree-of-freedom driving component II 222, a film clamping cylinder 223 being provided on the side wall of the structural member 221, and a pressure block 224 matching the size and position of the extension of the structural member 221 being provided on the output end of the film clamping cylinder 223, the pressure block 224 being driven by the film clamping cylinder 223 to abut against the surface of the structural member 221 to form a clamping station for clamping the film;

[0065] The bottom of the pressure block 224 is connected to the output end of the clamping cylinder 223 via multiple springs 225. When the springs 225 are not compressed, the height of the cutter 227 is lower than the height of the pressure block 224. The cutter 227 is located at the output end of the clamping cylinder 223 and is located outside the structural component 221. In this technical solution, the output end of the clamping cylinder 223 is provided with a guide post 226 that passes through the spring 225. The pressure block 224 has a through hole for the guide post 226 to extend into. The extension of the structural component 221 and the pressure block 224 are driven by the clamping cylinder 223 to achieve a clamping position for clamping the film. After clamping, the starting end of the film is moved to the film winding position by the drive component II 222. At the same time, the cutter 227 is located at the output end of the clamping cylinder 223 and outside the structural component 221. When the spring 225 is not compressed, the cutter 227, which is lower than the pressure block 224, will not contact the film. The film moves under the drive of the pressure block 224 and the structural component 221. When the clamping cylinder acts a second time, it compresses the spring 225, and the cutter 227 cuts the film clamped by the pressure block 224 and the structural component 221. By placing the cutter 227 and the pressure block 224 together, the film clamping and cutting are accomplished through a single structure. This significantly improves the equipment's efficiency by controlling the sequential movement of the film clamping cylinder 223.

[0066] It should be noted that in this device, the degrees of freedom of drive component I 38, drive component II 222, and drive component III 232 are all achieved by cylinder assemblies, and the applicant will not elaborate further here.

[0067] A film wrapping method, applied in the automatic film wrapping device for the outer surface of the cylindrical part, the film wrapping method comprising the following steps:

[0068] The cylindrical part 4 is gripped by the pneumatic gripper 12 of the hoisting fixture, and the area to be wrapped of the cylindrical part 4 is moved to the working position of the wrapping assembly 21 by adjusting the movement of the assembly.

[0069] Driven by the film clamping cylinder 223, the pressure block 224 of the upper film assembly 22 clamps the film at the clamping station formed between it and the structural component 221. Driven by the driving component II 222, the starting end of the film is moved to the working position. Driven by the driving component III 232, the film pressing sheet 231 abuts against the surface of the cylindrical component 4. The pressure block 224 is released, and the upper film assembly 22 moves to the initial position.

[0070] The film wrapping assembly 21 wraps two layers of film around the surface of the cylindrical body. The pressure film sheet 231 is pulled out by the drive component Ⅲ 232. The connector 212 of the film wrapping assembly 21 continues to wrap the cylindrical body 4. After the film wrapping is completed, the pressure film sheet 231 abuts against the surface of the cylindrical body again. The clamping station of the upper film assembly clamps the film. At the same time, the cutter 227 cuts the wrapped film under the drive of the clamping cylinder 223.

[0071] The suction cup I 341 of the gluing mechanism 3 adsorbs the tape before it is pasted, and forms a tape head on the tape through the folding component 33. Driven by the driving component I 38, it moves to the joint of the film break. With the cooperation of the driving component I 38 and the roller 35, the outer adhesive surface of the tape adheres to the film. At the same time, the suction cup I 341 stops adsorbing. The tape is stretched and pasted to the film under the action of the driving component I 38. The roller 35 firmly sticks the tape to the film. After the pasting is completed, the suction cup I 341 and suction cup II 342 adsorb the tape. The cutting blade of the cutting component 39 cuts the adsorbed and fixed tape to complete the pasting.

[0072] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made.

The bottom of the pressure block is connected to the output end of the clamping cylinder via multiple springs. When the springs are not compressed, the height of the cutter is lower than the height of the pressure block. The cutter is located at the output end of the clamping cylinder and on the outside of the structural component.

6. The automatic film wrapping device for the outer surface of a cylindrical part according to claim 3, characterized in that, The pressure film assembly includes a pressure film sheet, which, through a two-degree-of-freedom driving component III located at the bottom, makes the thin film in close contact with the outer surface of the cylindrical component.

7. A wrapping method, characterized in that, The automatic film wrapping device for the outer surface of a cylindrical part, as described in any one of claims 1-6, comprises the following steps: The cylindrical component is gripped by the pneumatic grippers of the hoisting mechanism, and the area to be wrapped on the cylindrical component is moved to the working position of the wrapping assembly by the movement of the height adjustment component. Driven by the clamping cylinder, the pressure block of the upper film assembly clamps the film at the clamping station formed between itself and the structural component. Driven by the driving component II, the starting end of the film is moved to the working position. Driven by the driving component III, the film pressing sheet abuts against the surface of the cylindrical component, the pressure block is released, and the upper film assembly moves to the initial position. The film wrapping assembly wraps multiple turns of film around the surface of the cylindrical part. After the film wrapping is completed, the pressure sheet abuts against the surface of the cylindrical part again, and the film loading assembly moves to the film cutting position again. The cutter cuts the wrapped film under the drive of the film clamping cylinder. The adhesive applicator's suction cup I adsorbs the tape before it is pasted, and forms a tape head on the tape through the folding component. Driven by the drive component I, it moves to the joint of the film break. With the cooperation of the drive component I and the roller, the outer adhesive side of the tape adheres to the film. At the same time, suction cup I stops adsorbing, and the tape is stretched and pasted. After the pasting is completed, suction cups I and II adsorb the tape. Finally, the cutting component cuts the adsorbed and fixed tape to complete the pasting.
