Description

Technical Field

[0001] The present invention relates to the field of automatic assembly, and more specifically, to an automatic film wrapping device and a film wrapping method for the outer surface of a columnar component. Background Art

[0002] In the field of large-scale industrial manufacturing and assembly and certain specific fields, especially in cylindrical parts (such as shafts and cylinders) that require electrical action, film winding technology is usually used. During the subsequent processing of the film, it is necessary to react with the cylindrical part so that the film-wrapped part of the cylindrical part can achieve the required physical properties. However, after the existing tape is attached to the film, it is tightly attached. The subsequent removal process is very troublesome. The film needs to be completely removed by destructive means, or part of the tape starting end will remain on the film surface, affecting the subsequent processing of the subsequent cylindrical parts.

[0003] In the existing film wrapping device, after the tape is wrapped, the subsequent unpacking process is very troublesome. The tape is in full contact with the surface of the object, and it is not easy to find the starting position of the tape. It is usually necessary to destroy the film to complete the removal of the tape. At the same time, in the process of taping, the existing device usually uses rollers and swing arms to fix the tape, which causes the tape surface to deflect during the pasting process, affecting the subsequent pasting work. For example, the packaging film fixing device of a wrapping packaging robot disclosed in patent application No. 202110490938.6 is in the process of working, but there are still deficiencies in the tape pasting. During the operation of the device, due to the roller control problem, the adhesive surface of the tape deflects during pasting, thereby affecting the pasting effect and product quality. At the same time, after completing the gluing work, in the subsequent process of removing the tape, since the tape is completely adhered to the film, it is difficult to find the starting point of the tape, and the subsequent unpacking process is very troublesome, and part of the tape will remain on the surface of the film.

[0052] Figure 1 The invention shows an automatic film winding device for the outer surface of a cylindrical member, comprising: a hoisting mechanism 1 for fixing and moving a cylindrical member 4 in space, a film-applying mechanism 2 for wrapping a film around a partial area of ​​the cylindrical member 4 on the hoisting mechanism 1, and a gluing mechanism 3 for fixing the cylindrical body after the film is wrapped with adhesive tape, wherein the gluing mechanism 3 performs a gluing operation on the film on the cylindrical body through a two-degree-of-freedom driving component Ⅰ38, and the gluing mechanism 3 comprises: a mounting member 31 fixedly connected to the Z-axis output end of the driving component Ⅰ38;

[0053] A capstan 32 for placing the tape is provided on an extension portion of one side of the mounting member 31;

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

[0055] An adsorption component 34 is arranged upstream and downstream of the folding component 33 and fixes the adhesive tape before pasting and the adhesive tape during cutting;

[0056] A cutting component 39 is provided between the adsorption components 34 and is used to cut the adhesive tape after being attached.

[0057] Working principle:

[0058] The hoisting mechanism 1 moves the columnar member 4 to the designated position and fixes it. The film-applying mechanism 2 is started to wrap the columnar member 4 with a film. After the film wrapping is completed, the gluing mechanism 3 is started, and the driving component I 38 drives the mounting member 31 to move above the columnar member 4. The capstan 32 releases the tape, and a tape head is formed 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 columnar member 4. The cutting component 39 cuts the tape at an appropriate position to complete a gluing operation. The hoisting mechanism 1 continues to move the columnar member 4 forward, and the film-applying mechanism 2 and the gluing mechanism 3 wrap different parts of the columnar body with film and fix them with glue. In order to achieve film wrapping protection for multiple different parts of the columnar member 4. The present invention forms a tape head before the tape is pasted by setting the folding component 33, which is convenient for the later processing of the tape on the film, avoiding damage to the tape, and then damaging the surface of the columnar member 4. At the same time, the adsorption component 34 adsorbs the tape before pasting and during cutting, thereby preventing the tape from shaking during the pasting process, which causes the adhesive surfaces of the tape to stick together, thereby improving the pasting efficiency of the device.

[0059] In the above technical solution, the adsorption component 34 includes: a suction cup I 341 and a suction cup II 342 respectively arranged upstream and downstream of the folding component 33, and the suction cup I 341 and the suction cup II 342 are connected to the external air source through the air inlet pipeline passing through the side wall of the installation groove. By adopting this technical solution, the suction cup I 341 and the suction cup II 342 have a cavity 343 on the surface of the mounting groove, and a porous plate 344 embedded in the cavity 343 is arranged above each cavity 343, and an air pipe joint connected with the corresponding cavity 343 is arranged on the side wall of the mounting groove, and the cavity 343 is connected with an external air source through the air inlet pipeline on the air pipe joint to form a negative pressure on the suction cup I 341 and the suction cup II 342. When the negative pressure is formed on the suction cup I 341, the non-adhesive surface of the tape fits tightly, ensuring that the tape does not shake in the air when it is not pasted. Once the tape is pasted to the film, the external air source stops working, the suction cup I 341 does not adsorb the tape, and the tape is pasted normally. After the pasting is completed, the external air source is started, and the suction cup I 341 and the suction cup II 342 adsorb the tape, ensuring that the tape is cut and pasted to the film with smoothness.

[0060] In the above technical solution, the hoisting mechanism 1 comprises: a fixing plate 11, on which pneumatic clamps 12 for grabbing the columnar member 4 are arranged in pairs, and a height adjustment component is arranged between the fixing plate 11 and the pneumatic clamps 12;

[0061] The height adjustment assembly is slidably arranged on the slide rail of the fixed plate 11, and the pneumatic clamp 12 is arranged on the height adjustment assembly. With this technical solution, the height adjustment assembly includes: a connecting plate 13 for mounting the pneumatic clamp 12, a support frame 14 slidably connected to the fixed plate 11, a lifting bracket 15 arranged between the connecting plate 13 and the support frame 14, and a driving cylinder 17 arranged on the support frame 14 and connected to the free end of the lifting bracket 15. The lifting bracket 15 is composed of two connecting rods hinged in the middle to form an X-shaped lifting bracket 15. 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 the 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 the slider II 16 sliding on the connecting plate 13. The output end of the driving cylinder 17 is fixedly connected to the slider I, and the fixed plate 11 is provided with a driving component IV for moving the support frame 14 forward and backward along the fixed plate 11.

[0062] In the above technical solution, the film-applying mechanism includes: a film-wrapping assembly 21 for wrapping the outer surface of the columnar member 4 with multiple turns of film; an upper film assembly 22 for moving the film on the film-wrapping assembly 21 from the starting position to the working position; a film-pressing assembly 23 for making the film fit tightly against the surface of the columnar member 4 during wrapping; and a cutter 227 provided on the upper film assembly 22 for cutting the film after wrapping. With this technical solution, before film wrapping begins, the starting end of the film is inserted into the clamping station formed by the structural member 221 and the pressing block 224 for clamping, and driven by the driving component II 222, the starting end of the film is moved to the working position, and the film-pressing sheet 231 is driven by the driving component III 232 to make the film fit tightly against the surface of the columnar member 4, and at the same time, the film-clamping cylinder 223 releases the pressing block 224, and the starting end of the film is released, but under the action of the film-pressing sheet 231, the rear end of the film continues to keep in contact with the columnar member 4. The drive motor 214 drives the rack 215 on the lower connecting member 212, and the connecting member 212 makes a circular motion around the annular guide rail of the mounting plate 211. The film roll 213 on the connecting member 212 wraps the cylindrical member 4. After wrapping two circles, the film pressing sheet 231 moves backward and is pulled out from the wrapped film to avoid subsequent over-tightening of the film pressing sheet, which makes it difficult to pull out the film pressing sheet. The connecting member 212 is also provided with a tensioning rod 216 that forms a certain pre-tightening force during the film pulling process, ensuring that the film is wrapped. , and can be wrapped tightly enough with the cylindrical member 4. After the wrapping is completed, the film pressing sheet 231 is again pressed against the outer surface of the film wrapping area of ​​the cylindrical member 4. At the same time, the clamping station formed by the structural member 221 and the pressing block 224 is pressed tightly against the film to be cut. At the same time, the film clamping cylinder 223 acts for the second time, so that the spring 225 between the film clamping cylinder 223 and the pressing block 224 is compressed, and the height of the cutter 227 is higher than the surface of the structural member 221 to cut the film. After the cutting is completed, the folding motor 332 on the mounting member 31 drives The folding piece 331 forms a tape head at the suction cup I 341. The suction cup I 341 is connected to the external air source through the air inlet pipeline on the air pipe joint to form a negative pressure to adsorb the tape head. The mounting part 31 is driven by the driving component I 38 to make a small arc movement around the film seam on the surface of the cylindrical part 4. After the adhesive surface at the tape head contacts the film, the suction cup I 341 stops adsorption, and with the cooperation of the driving component I 38 and the rubber roller 35, the tape is stretched while the rubber roller 35 makes the tape and the film fit tightly. After the pasting is completed, the suction cup I 341 and the suction cup II 342 form a negative pressure to adsorb the tape, and the rubber cutting knife of the cutting component 39 cuts the tape to complete the film pasting and fixing.The film pressing sheet 231, the mounting member 31 and the structural member 221 all return to their initial positions to prepare for the next film wrapping. At the same time, the driving component IV drives the support frame 14 to move on the fixed plate 11, and the columnar member 4 moves back and forth in space driven by the pneumatic clamp 12. The notches on the mounting plate 211 and the connecting member 212 enable the connecting arm of the pneumatic clamp 12 to pass through the mounting plate 211 and the connecting member 212 to move multiple parts to be wrapped on the columnar member 4 to the film wrapping station of the wrapping assembly.

[0063] It also includes: a traveling roller 36 and an anti-slip roller 37 arranged between the installation grooves to form a certain pre-tightening force on the tape during the transmission process, and the anti-slip roller 37 is located between the two traveling rollers 36. With this technical solution, the traveling roller 36 and the anti-slip roller 37 are arranged inside the installation groove to form the movement direction of the tape in space. At the same time, the anti-slip roller 37 contacts the adhesive surface of the tape to prevent the tape from falling off during the tape application process.

[0064] In the above technical solution, the upper film assembly 22 comprises: an inverted L-shaped structural member 221, the structural member 221 contacts the film of the film wrapping assembly 21 through a three-degree-of-freedom driving component II 222, a film clamping cylinder 223 is arranged on the side wall of the structural member 221, and a pressing block 224 matching the size and position of the extension part of the structural member 221 is arranged on the output end of the film clamping cylinder 223, and the pressing block 224 is 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 pressing block 224 is connected to the output end of the film clamping cylinder 223 through a plurality of springs 225. When the springs 225 are not compressed, the height of the cutter 227 is lower than the height of the pressing block 224. The cutter 227 is arranged at the output end of the film clamping cylinder 223 and is located on the outside of the structural member 221. By adopting this technical solution, a guide column 226 penetrating a spring 225 is provided at the output end of the film clamping cylinder 223, and a through hole for the guide column 226 to extend into is opened on the pressure block 224. The extension portion of the structural member 221 and the pressure block 224 realize a clamping station for clamping the film under the drive of the film clamping cylinder 223. After clamping, the starting end of the film is moved to the film wrapping working position under the drive of the driving component II 222. At the same time, the cutter 227 is located at the output end of the film clamping cylinder 223 and at the outside of the structural member 221. When the spring 225 is not compressed, the cutter 227 below the pressure block 224 will not contact the film. The film moves under the drive of the pressure block 224 and the structural member 221. When the clamping cylinder acts for the second time to compress the spring 225, the cutter 227 cuts off the film clamped by the pressure block 224 and the structural member 221. The cutter 227 and the pressing block 224 are arranged together, so that the film clamping and the film cutting are completed by one structure, and it is only necessary to control the sequential actions of the film clamping cylinder 223, which greatly improves the working efficiency of the equipment.

[0066] It should be noted that, in the present device, the degrees of freedom of the driving component I38, the driving component II222, and the driving component III232 are all realized by using cylinder assemblies, and the applicant will not elaborate on them in detail.

[0069] The pressing block 224 of the upper film assembly 22 is driven by the film clamping cylinder 223 to clamp the film at the clamping position formed between the structural member 221, and the starting end of the film is moved to the working position under the drive of the driving member II 222. The film pressing sheet 231 is driven by the driving member III 232 to abut against the surface of the columnar member 4, the pressing block 224 is released, and the upper film assembly 22 moves to the initial position.

[0070] The film wrapping assembly 21 wraps the surface of the cylindrical body with two circles of film, and the film pressing sheet 231 is pulled out by the driving component III 232, and the connecting member 212 of the film wrapping assembly 21 continues to wrap the cylindrical member 4. After the film wrapping is completed, the film pressing sheet 231 is again pressed against the surface of the cylindrical body, and the clamping station of the upper film assembly clamps the film. At the same time, the cutter 227 is driven by the film clamping cylinder 223 to cut the film after winding.

[0071] The suction cup Ⅰ341 of the gluing mechanism 3 absorbs the tape before it is pasted, and forms a tape head on the tape through the folding component 33, and is driven by the driving component Ⅰ38 to move to the joint of the film fracture, and with the cooperation of the driving component Ⅰ38 and the rubber roller 35, the outer adhesive surface of the tape is bonded to the film, and the suction cup Ⅰ341 stops adsorbing at the same time. The tape is stretched and adhered to the film under the action of the driving component Ⅰ38, and the rubber roller 35 adheres the tape to the film tightly. After the pasting is completed, the suction cup Ⅰ341 and the suction cup Ⅱ342 absorb the tape, and the glue cutting knife of the cutting component 39 cuts the adsorbed and fixed tape to complete the pasting.
