[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like components.

[0059] In the following description, words such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined relative to the structure shown in the drawings. In particular, "height" is equivalent to the dimension from top to bottom, "width" is equivalent to the dimension from left to right, and "depth" is equivalent to the dimension from front to back. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directions should not be interpreted as restrictive terms.

[0060] Terms related to attachment, coupling, and the like (eg, "connected" and "attached") refer to either a fixed or attached relationship between structures, either directly or indirectly, and either movable or rigid attachments or relationships, unless expressly stated otherwise, of the structures to one another through intermediate structures.

[0061] According to one embodiment of the present invention, Figure 1~Figure 4 As shown in FIG. 1 , it can be seen that the self-sustaining film sticking mechanism 3 includes:

[0062] Film supply and stripping assembly 31;

[0063] A translation assembly 32, which is disposed on the film supply and stripping assembly 31 or located beside the film supply and stripping assembly 31;

[0064] A lifting assembly 35, which is in transmission connection with the translation assembly 32;

[0065] A film mounting frame 36 is connected to the lifting assembly 35 in a transmission manner. The film mounting frame 36 is driven by the lifting assembly 35 to reciprocate along the Z axis; and

[0066] The film suction assembly 37 and the side film rolling assembly 33 installed on the film mounting frame 36,

[0067] The film mounting frame 36 can perform translational motion along the X-axis direction and the Y-axis direction in a horizontal plane under the drive of the translational component 32 together with the lifting component 35 .

[0068] Next, refer to Figure 5 and Figure 6 , wherein the specific structure of the film supply and stripping assembly 31 is shown in detail. Specifically, the film supply and stripping assembly 31 includes:

[0069] Mounting base 311; and

[0070] A coil mounting frame 312, which is slidably connected to the mounting base 311;

[0071] A coil material discharge tray 313, which is rotatably connected to the coil material mounting frame 312, and a film coil material is wound on the coil material discharge tray 313;

[0072] A release paper receiving roller 315 rotatably connected to the roll material mounting frame 312 ; and

[0073] The film stripping module 318 is provided with a wedge-shaped film tensioning die head 3181.

[0074] The coil mounting frame 312 is provided with a coil guide rail extending in the Y-axis direction, and the film coil released from the coil discharge tray 313 is gradually laid flat on the coil guide rail, and is wound around the wedge-shaped tip of the film tensioning die 3181 and then wound up by the release paper receiving roller 315. The film coil is made of a flexible material, and after being bent by the wedge-shaped tip of the film tensioning die 3181, the film on it becomes easy to be peeled off, and the coil guide rail can prevent the film coils released from the coil discharge tray 313 from being entangled with each other.

[0075] Next, we will refer to Figure 6 , wherein the specific structure of the film stripping assembly 318 is shown in detail. The film stripping module 318 is also provided with a film stripping driver 3182, and the film tensioning die head 3181 is transmission-connected to the film stripping driver 3182.

[0076] Furthermore, the roll material mounting frame 312 includes a roller mounting plate 3122 and a roll material mounting plate 3121, and the roller mounting plate 3122 and the roll material mounting plate 3121 are integrally combined to form an L-shaped roll material mounting frame 312, wherein the roll material unloading tray 313 is rotatably connected to the roll material mounting plate 3121, and the release paper receiving roller 315 and the film stripping module 318 are arranged on the roller mounting plate 3122.

[0077] Refer again Figure 6The upper surface of the film tensioning die 3181 is flush with the coil guide rail, so that the film roll laid flat on the coil guide rail can be smoothly guided to the film tensioning die 3181. The film tensioning die 3181 is driven by the film peeling driver 3182 and moves horizontally along the unwinding direction of the film roll, so that the unwound film roll is always in a tensioned state, thereby improving the success rate of film peeling.

[0078] In this embodiment, a film pressing plate 3183 is detachably mounted on the upper surface of the film tensioning die 3181, and a film stripping gap is formed between the film pressing plate 3183 and the film tensioning die 3181. The film coil introduced into the upper surface of the film tensioning die 3181 passes through the film stripping gap. Preferably, the film pressing plate 3183 is arranged near the wedge-shaped tip of the film tensioning die 3181, so that the film after stripping can remain flat, and prevent the subsequent film absorption and attachment from becoming difficult due to curling after separation from the release paper. In addition, the detachable installation method can realize the function of quickly replacing the film coil.

[0079] Furthermore, assuming that the thickness of the film roll is h, the thickness of the film after peeling off the release paper is d, and the thickness of the film peeling gap is H, then h≤H≤h+d. Using a film peeling gap of this thickness can prevent the film from curling while ensuring that the film roll can pass through the film peeling gap smoothly.

[0080] Refer again Figure 6 In order to ensure the winding of the release paper after the film is peeled off, an auxiliary winding module 316 is provided between the film peeling module 318 and the release paper receiving roller 315, and the auxiliary winding module 316 includes:

[0081] Lower pressure roller 3162;

[0082] an auxiliary winding roller 3161 , which is opposite to and spaced from the lower pressing roller 3162 ; and

[0083] The auxiliary winding driver 3163 is connected to the auxiliary winding roller 3161 in a transmission manner.

[0084] The film coil released from the coil unwinding tray 313 first passes around the wedge-shaped tip of the film tensioning die 3181, then passes between the lower pressure roller 3162 and the auxiliary winding roller 3161, and is finally wound up by the release paper receiving roller 315. The auxiliary winding module 316 can prevent the release paper from being broken due to the deviation of the winding force caused by the excessive length of the winding path, and can effectively improve the winding efficiency and winding success rate.

[0085] Furthermore, at least one tensioning roller 3132 in rolling contact with the film coil is provided on the conveying path of the film coil.

[0086] Furthermore, a sliding guide rail 3111 is fixedly connected to the mounting base 311, and the coil mounting frame 312 is slidably connected to the sliding guide rail 3111, wherein the coil mounting frame 312 is provided with a horizontal position adjustment structure 319 for adjusting its position on the sliding guide rail 3111. Figure 2 The right end of the mounting base 311 is fixedly connected to a limiting plate 314, and a plurality of snap-in holes are opened on the limiting plate 314. A snap-in terminal corresponding to the snap-in hole is provided at the front end of the coil mounting rack 312. According to actual use needs, the coil mounting rack 312 can reciprocate the left and right positions of the coil mounting rack 312 on the sliding guide rail 3111 through the horizontal position adjustment structure 31, so that the coil mounting rack 312 and the limiting plate 314 are selectively snap-connected, thereby realizing the rapid replacement and installation of different types of coil mounting racks 312 according to actual use needs.

[0087] Refer again Figure 2~Figure 4 , wherein the specific structure of the translation assembly 32 is shown in detail, specifically, the translation assembly 32 includes:

[0088] Translation support 323;

[0089] An X-axis translation module 321, which is disposed on the translation bracket 323;

[0090] The Y-direction translation module 322 is connected to the X-direction translation module 321 in a transmission manner.

[0091] Among them, the X-axis translation module 321 includes an X-axis translation guide rail 3211 extending along the X-axis direction and an X-axis driver 3212 arranged on the X-axis translation guide rail 3211, and the Y-axis translation module 322 includes a Y-axis translation guide rail 3221 extending along the Y-axis direction and a Y-axis driver arranged on the Y-axis translation guide rail 3221. The Y-axis translation guide rail 3221 is transmission-connected to the X-axis driver 3212, so that the Y-axis translation guide rail 3221 reciprocates along the X-axis translation guide rail 3211 under the drive of the X-axis driver 3212.

[0092] Furthermore, the lifting assembly 35 includes:

[0093] A lifting guide rail 351, which is in driving connection with the Y-direction drive; and

[0094] The lifting driver 352 is disposed on the lifting guide rail 351 and is in driving connection with the film mounting frame 36.

[0095] Wherein, the lifting guide rail 351 moves back and forth along the Y-direction translation guide rail 3221 under the drive of the Y-direction driver.

[0096] Furthermore, the film suction assembly 37 comprises:

[0097] Gas source;

[0098] A horizontal rotation module 371, which is disposed on the film mounting frame 36; and

[0099] The film suction nozzle 372 is arranged on the power output end of the flat rotating module 371 and is connected to the air source.

[0100] The film suction nozzle 372 can rotate in a horizontal plane under the drive of the translation module 371 to adjust the posture of the film suction nozzle 372 in the horizontal plane.

[0101] In this embodiment, the end of the coil guide rail is provided with a film detection module 34 located below the plane where the coil guide rail is located. Furthermore, a film recovery bucket 355 is provided next to the film detection module 34. After the film detection module 34 detects that the current film is damaged, the film is put into the film recovery bucket 355 for recovery under the cooperation of the translation component 32 and the lifting component 35; if the current film posture is found to be deviated, the corresponding rotation compensation is performed through the translation module 371.

[0102] Reference Figure 7 and Figure 8 , wherein the specific structure of the side film rolling assembly 33 is shown in detail, and the side film rolling assembly 33 includes:

[0103] A rolling base 331, which is mounted on the film mounting frame 36;

[0104] A left roller 332 and a right roller 333 are arranged opposite to each other, and the left roller 332 and the right roller 333 can rotate in opposite directions relative to the roller base 331 so that the left roller 332 and the right roller 333 can change between a closed state and an open state; and

[0105] A reset component is disposed on the rolling base 331 and acts on the left rolling member 332 and the right rolling member 333 respectively.

[0106] The resetting component can be elastically deformed, and is used to rotate the left roller 332 and the right roller 333 in a direction of closing together to return from the open state to the closed state. Figure 7The cylindrical product 4 to be rolled and pasted is located directly below the side film rolling assembly 33 and is opposite to the left rolling piece 332 and the right rolling piece 333. The cylindrical surface of the product 4 to be rolled and pasted is provided with a film to be rolled and pasted. When the side film rolling assembly 33 descends in the vertical direction, the left rolling piece 332 and the right rolling piece 333 thereon will roll and pasted the cylindrical surface of the product 4 to be rolled and pasted in the left and right areas respectively. After completing one rolling, the preliminarily pasted film can be rolled through multiple lifting and lowering to roll out the residual bubbles in the film, thereby improving the firmness of the film attached to the product 4 to be rolled and pasted, thereby improving the film pasting quality. Figure 8 The rolling base 331 is provided with a first hinge point 3311 and a second hinge point 3312. One end of the left rolling member 332 is rotatably connected to the first hinge point 3311, and one end of the right rolling member 333 is rotatably connected to the second hinge point 3312. The other end of the left rolling member 332 forms a left rolling point, and the other end of the right rolling member 333 forms a right rolling point. During the rolling film laminating process, the left rolling point and the right rolling point are kept in contact with the cylindrical surface of the product 4 to be rolled and laminating under the action of the reset component.

[0107] Furthermore, a left stop column 338 and a right stop column 339 are fixedly provided on the rolling base 331. The left stop column 338 and the right stop column 339 are respectively located on the closing path of the left rolling member 332 and the right rolling member 333, and are used to respectively block the closing force of the left rolling member 332 and the right rolling member 333, so that when the side film rolling assembly is not subjected to other external forces, the left rolling point is at least blocked directly below the first hinge point 3311, and the right rolling point is at least blocked directly below the second hinge point 3312.

[0108] Furthermore, the left roller 332 includes:

[0109] A left roller body 3322; and

[0110] The left detour portion 3323 is fixedly connected to the left rolling body 3322 and forms the left rolling point at its end.

[0111] The left detour portion 3323 is bent toward the right rolling member 333. During the continuous descent of the side film rolling assembly 33, the left detour portion 3323 enables the left rolling point to keep in continuous contact with the left lower cylindrical surface of the product 4 to be rolled without interference after passing over the leftmost end 42 of the cylindrical surface of the product 4 to be rolled, thereby ensuring that the rolling and laminating of the left lower cylindrical surface can proceed smoothly.

[0112] Furthermore, a left bending portion 3321 is provided on the left roller body 3322, and the left bending portion 3321 and the left detour portion 3323 are respectively fixed to the two ends of the left roller body 3322, wherein the left bending portion 3321 is bent toward the right roller member 333, and the left roller member 332 is rotatably connected to the first hinge point 3311 through the left bending portion 3321.

[0113] Furthermore, the right rolling member 333 includes:

[0114] a right rolling body 3332; and

[0115] The right detour portion 3333 is fixedly connected to the right rolling body 3332 and forms the right rolling point at its end.

[0116] The right detour portion 3333 is bent toward the left rolling member 332. During the continuous descent of the side film rolling assembly 33, the right detour portion 3333 enables the right rolling point to keep in continuous contact with the right lower cylindrical surface of the product 4 to be rolled without interference after passing over the rightmost end of the cylindrical surface of the product 4 to be rolled, thereby ensuring that the rolling and laminating of the right lower cylindrical surface can proceed smoothly.

[0117] Furthermore, the right roller body 3332 is provided with a right bending portion 3331, and the right bending portion 3331 and the right detour portion 3333 are respectively fixed to the two ends of the right roller body 3332, wherein the right bending portion 3331 is bent toward the left roller member 332, and the right roller member 333 is rotatably connected to the second hinge point 3312 through the right bending portion 3331. The arrangement of the left bending portion 3321 and the right bending portion 3331 can expand the accommodation space between the left roller member 332 and the right roller member 333, and facilitate the reasonable arrangement of the left blocking column 338 and the right blocking column 339 in the accommodation space.

[0118] In a preferred embodiment, the left roller pressing point and the right roller pressing point are rotatably connected to the left roller pressing wheel 334 and the right roller pressing wheel 335 respectively. Figure 2, which shows in detail the initial state of the side film rolling assembly 33 when no other external force is applied. Specifically, the left rolling member 332 is rotatably connected to the first hinge point 3311 and hangs downward from the first hinge point 3311, so that the left roller 334 rotatably connected thereto is located directly above the highest point 41 of the cylindrical surface of the film-applying product 4 to be rolled in this initial state; the right rolling member 333 is rotatably connected to the second hinge point 3312 and hangs downward from the second hinge point 3311. 12 is suspended downwardly, so that the right roller pressing wheel 335 rotatably connected thereto is located above the left roller pressing wheel 334 in the initial state; wherein, the projections of the left roller pressing wheel 334 and the right roller pressing wheel 335 on the horizontal plane at least partially overlap, and when the side film rolling assembly 33 descends to roll and apply film, the left roller pressing wheel 334 first contacts the highest point 41 of the cylindrical surface of the product 4 to be rolled and applied with film, and as the side film rolling assembly 33 continues to descend, the left roller pressing member 332 contacts the highest point 41 of the cylindrical surface of the product 4 to be rolled and applied with film, and as the side film rolling assembly 33 continues to descend, the left roller pressing member 332 contacts the highest point 41 of the cylindrical surface of the product 4 to be rolled and applied with film, and The left roller 334 starts to rotate clockwise under the reaction force of the film-applied product 4, thereby pulling the left roller 334 to roll from the highest point 41 along the cylindrical surface of the film-applied product 4 to be rolled to the lower left. After the left roller 334 rolls for a distance, the right roller 335 starts to contact the cylindrical surface of the film-applied product 4 to be rolled. As the side film rolling assembly 33 continues to descend, the right roller 333 starts to rotate counterclockwise under the reaction force of the film-applied product 4 to be rolled, thereby pulling the right roller 334 to roll along the cylindrical surface of the film-applied product 4 to be rolled. 35 starts from the vicinity of the highest point 41 and rolls along the cylindrical surface of the film-applying product 4 to be rolled to the lower right, and under the action of the restoring force of the reset component, the left roller 334 and the right roller 335 can always keep in contact with the cylindrical surface of the film-applying product 4 to be rolled during the rolling process, and can even keep in contact with the cylindrical surface of the film-applying product 4 after passing the leftmost end 42 of the cylindrical surface and the rightmost end 43 of the cylindrical surface, and finally reach the lowest end 44 of the cylindrical surface, thereby completing one rolling film application.

[0119] Refer again Figure 8 , which further shows other improved structures, specifically, the left roller 332 and the right roller 333 are respectively fixed with a left limiter 3324 and a right limiter 3334, and the roller base 331 is fixed with a left guide 336 and a right guide 337, so that when the left roller 332 and the right roller 333 are opened to their respective maximum opening angles, the left limiter 3324 is at least partially inserted into the left guide 336, and the right limiter 3334 is at least partially inserted into the right guide 337. This structural design can prevent the left roller 332 and the right roller 333 from rotating unsteadily when the opening angle is too large, thereby improving the structural stability.

[0120] Further, assuming that the maximum opening angle of the left roller 332 is α, and the maximum opening angle of the right roller 333 is β, then 15°≤α≤75°, 15°≤β≤75°. In this embodiment, α=β=65°.

[0121] In one embodiment, the axial lengths of the left roller 334 and the right roller 335 are slightly larger than the axial size of the film-applying product 4 to be rolled, and the wheel surfaces of the left roller 334 and the right roller 335 are provided with rolling grooves recessed along their respective radial directions. The setting of the rolling grooves can prevent the film from shifting during the rolling process and other inaccurate positioning problems.

[0122] Now refer to Figure 9~Figure 11 , which shows another embodiment of the film supply and stripping assembly 31. It can be seen that in this embodiment, the film supply and stripping assembly 31 includes:

[0123] A mounting base 311 on which a sliding guide rail 3111 is fixedly connected; and

[0124] A coil mounting frame 312, which is slidably connected to the mounting base 311 via the sliding guide rail 3111;

[0125] A coil material discharge tray 313, which is rotatably connected to the coil material mounting frame 312, and a film coil material is wound on the coil material discharge tray 313;

[0126] Wherein, the horizontal position adjustment structure 319 includes:

[0127] A push rod 3191, which is rotatably connected to the coil mounting frame 312 near the middle section to form a push end and a transmission end located at both ends thereof, the push end is used to receive the thrust, and the transmission end is used to transmit the thrust;

[0128] The actuating rod 3194 is rotatably connected to the coil mounting frame 312 near the middle section to form a receiving end and an actuating end located at both ends thereof, the receiving end is used to receive the thrust from the transmission end, and the actuating end extends between the coil mounting frame 312 and the mounting base 311 and acts on the mounting base 311, so that the actuating rod 3194 can reciprocately adjust the relative position of the coil mounting frame 312 on the sliding guide rail 3111 by acting on the actuating end of the mounting base 311 under the push of the pushing rod 3191. Figure 2 The rotation fulcrum on the push rod 3191 is the first rotation point 31911, and the rotation fulcrum on the actuating rod 3194 is the second rotation point 31941.

[0129] Furthermore, a transmission groove 3112 is provided on the surface of the mounting base 311 opposite to the coil mounting frame 312, and the actuating end is inserted into the transmission groove 3112; wherein, a roller 3196 is rotatably connected to the actuating end, and the dimension of the transmission groove 3112 in the sliding direction of the coil mounting frame 312 is larger than the diameter of the roller 3196, so that the roller 3196 has sufficient actuating space in the transmission groove 3112. In a preferred embodiment, assuming that the dimension of the transmission groove 3112 in the sliding direction of the coil mounting frame 312 is L, and the diameter of the roller 3196 is D, then L:D=1.3~2. The provision of the roller 3196 can prevent the actuating end of the actuating rod 3194 from being worn or even damaged due to stress concentration during long-term rotation, and also improves the transmission smoothness.

[0130] Reference Fig. 9 and Fig.11 , which shows in detail a further improved implementation of the horizontal position adjustment structure 319, specifically, a transmission assembly for indirectly transmitting thrust is connected between the push rod 3191 and the actuating rod 3194, and the transmission assembly includes:

[0131] A substantially L-shaped bending member 3193, which is rotatably connected to the coil mounting frame 312 at a bending portion 31931 to form a left hinged end and a right hinged end located at two ends thereof respectively;

[0132] A first connecting rod 3192, which is rotatably connected between the transmission end of the push rod 3191 and the right hinge end; and

[0133] The second connecting rod 3199 is rotatably connected between the receiving end and the left hinge end of the actuating rod 3194. The transmission assembly can make the thrust transmission process smooth, and can prevent the roll material mounting frame 312 from sliding too fast on the mounting base 311 due to the excessive rotation angular velocity of the pushing rod 3191 and the actuating rod 3194 when the pushing end of the pushing rod 3191 is pulled, thereby preventing the problem that the sliding distance of the roll material mounting frame 312 on the mounting base 311 is difficult to control.

[0134] Refer again Fig.11 The bending piece 3193 is formed with a convex side and a concave side, and the coil mounting frame 312 is fixedly connected with a first rotation stabilizing piece 3195 opposite to the concave side. The bending piece 3193 can always maintain contact with the first rotation stabilizing piece 3195 on the concave side of the bending piece 3193 during its rotation.

[0135] Furthermore, an arc-shaped first stabilizing surface is formed on the first rotation stabilizing member 3195, and an arc-shaped first contact surface 31932 is formed on the concave side of the bending member 3193. The first rotation stabilizing member 3195 maintains smooth contact with the first contact surface 31932 through the first stabilizing surface. This structure can ensure that the bending member 3193 remains stable during rotation, preventing rotation instability caused by loose connection between the bending part 31931 and the coil mounting frame 312 after long-term transmission.

[0136] Furthermore, a limiter is connected near the actuating end of the actuating rod 3194, the limiter is slidably coupled with the first rotation stabilizing member 3195, and a limiter end 31951 protruding from its surface is formed at the end of the limiter. The limiter limits the maximum rotation angle of the actuating rod 3194.

[0137] Refer again Fig.11 A second rotation stabilizing member 3198 opposite to the receiving end of the actuating rod 3194 is fixedly provided on the coil mounting frame 312, and the actuating rod 3194 always keeps in contact with the second rotation stabilizing member 3198 during its rotation.

[0138] Furthermore, an arc-shaped second contact surface 31981 is formed on the side surface of the second rotation stabilizing member 3198 opposite to the receiving end of the actuating rod 3194, and the actuating rod 3194 always maintains smooth contact with the second contact surface 31981 through its receiving end during its rotation. With this structure, the actuating rod 3194 can be kept stable during the rotation process, and the rotation instability problem caused by the loose connection between the second rotation point 31941 on the actuating rod 3194 and the coil mounting frame 312 after long-term transmission can be prevented.

[0139] Furthermore, the coil mounting frame 312 is provided with an elastic return member 3197 acting on the actuating end of the actuating rod 3194. The elastic return member 3197 can exert elastic restoring force so that the actuating rod 3194 returns to the initial position after completing an actuating action on the mounting base 311.
