[0051] The present application will be further described in detail below with reference to the accompanying drawings.

[0052] Referring to Figure 1 As shown, a film feeding mechanism is shown, which includes a frame 1, on which a feeding assembly 8, a unwinding assembly 2, a receiving assembly 6 and a cutting assembly 3 are respectively arranged.

[0053] In this embodiment, in combination with Figure 2 As shown, the unwinding assembly 2 includes an unwinding shaft 21 rotatably arranged around its own axis, and a first driving module 22 for driving the unwinding shaft 21 to rotate. The unwinding shaft 21 extends along the horizontal direction. The first driving module 22 is a motor. On both sides of the unwinding shaft 21, mounting modules 23 for mounting the unwinding rollers 100 are respectively arranged, and the unwinding rollers 100 are wound with films.

[0054] In this way, the unwinding rollers 100 can be mounted on both mounting modules 23. The two unwinding rollers 100 are in a standby and in-use state and can realize the conversion of position and working state through the rotation of the unwinding shaft 21, greatly improving the film laying efficiency. Specifically, after the film on the working unwinding roller 100 is completely unwound, the first driving module 22 drives the unwinding shaft 21 to rotate and converts the positions of the working unwinding roller 100 and the standby unwinding roller 100. The standby unwinding roller 100 reaches the working position and continues to unwind the film, without stopping the equipment, and the working efficiency is high. At the same time, the working unwinding roller 100 after unwinding reaches the unloading position, and the worker can conveniently unload the working unwinding roller 100 and replace it with a fully loaded unwinding roller 100.

[0055] In this embodiment, the two mounting modules 23 are arranged vertically. The working unwinding roller 100 is mounted on the upper mounting module 23, and the standby unwinding roller 100 is mounted on the lower mounting module 23. Each mounting module 23 includes a first mounting seat 231 and a second mounting seat 232 respectively arranged at both ends of the unwinding shaft 21. On the first mounting seat 231 and the second mounting seat 232, air shafts 233 for docking with the unwinding roller 100 are respectively arranged. The two air shafts 233 can respectively dock with both ends of the unwinding roller 100, greatly facilitating the installation of the unwinding roller 100 by the worker and improving the installation efficiency. A protective shell 24 is also sleeved in the middle of the unwinding shaft 21, and the first driving module 22 is accommodated in the protective shell 24.

[0056] In this embodiment, in combination with Figure 3As shown in the figure, the loading component 8 includes a liftable loading seat 81 and two driving seats 82 respectively located at both ends of the loading seat 81. An eighth driving module 83 is respectively arranged on each driving seat 82. Both ends of the loading seat 81 are movably embedded in the two driving seats 82 respectively, and the output ends of the two eighth driving modules 83 are respectively connected to both ends of the loading seat 81. Among them, the eighth driving module 83 is a cylinder, and the piston rod of the cylinder extends along the vertical direction. During use, the unwinding roller 100 is placed on the loading seat 81, and the two cylinders drive the unwinding roller 100 to rise between the first mounting seat 231 and the second mounting seat 232. Subsequently, the first mounting seat 231 and the second mounting seat 232 are docked with both ends of the unwinding roller 100.

[0057] In this embodiment, referring again to Figure 2 As shown in the figure, a clamping component 4 is arranged at one end of the unwinding shaft 21, and a deviation rectifying component 5 is arranged at the other end.

[0058] The clamping component 4 includes a clamping seat 41 sleeved on the unwinding shaft 21. The two first mounting seats 231 are respectively arranged on both sides of the clamping seat 41 slidably along the length direction of the unwinding shaft 21. The clamping component 4 further includes two third driving modules 42 respectively used for driving the two first mounting seats 231 to slide.

[0059] The deviation rectifying component 5 includes a deviation rectifying seat 51 sleeved on the unwinding shaft 21. The two second mounting seats 232 are respectively arranged on both sides of the deviation rectifying seat 51 slidably along the length direction of the unwinding shaft 21. The deviation rectifying component 5 further includes two gears 52 respectively rotatably arranged on the two second mounting seats 232 around the vertical direction, a fourth driving module 53 for driving the two gears 52 to rotate. Rack bars 54 meshing with the two gears 52 are respectively arranged on both sides of the deviation rectifying seat 51, and the rack bars 54 extend along the sliding direction of the second mounting seat 232.

[0060] When installing the unwinding roller 100, first, the third driving module 42 is used to drive the first mounting seat 231 to slide. The first mounting seat 231 approaches and docks with one end of the unwinding roller 100 during the sliding process. Subsequently, the first mounting seat 231 pushes the unwinding roller 100 to slide and makes its other end dock with the second mounting seat 232. Then, the fourth driving module 53 drives the gear 52 to rotate. The gear 52 cooperates with the rack bar 54 and drives the second mounting seat 232 to move towards or away from the unwinding roller 100, realizing short-distance and high-precision position adjustment of the second mounting seat 232. In this way, the unwinding roller 100 can be tightly installed between the first mounting seat 231 and the second mounting seat 232 under the action of the clamping component 4, and the installation position and angle can be adjusted under the action of the deviation rectifying component 5. The adjustment precision is high, effectively improving the installation strength of the unwinding roller 100.

[0061] In this embodiment, referring toFigure 4 As shown in the figure, the material receiving assembly 6 is located above the unwinding assembly 2. It includes a material receiving base 61, a heating block 62 provided on the material receiving base 61, a clamping frame 63 rotatably provided on the material receiving base 61, and a fifth driving module 64 for driving the clamping frame 63 to rotate. The material receiving base 61 is parallel to the unwinding shaft 21. The adhesive films output by the two unwinding rollers 100 can respectively pass around the material receiving base 61. The clamping frame 63 is used to clamp the two groups of adhesive films onto the heating block 62.

[0062] Among them, an electric heating rod is accommodated in the heating block 62. The fifth driving module 64 is a motor. A second rotating shaft 65 is provided in parallel on the side of the material receiving base 61. L-shaped connecting frames 66 are respectively provided at both ends of the second rotating shaft 65. The two connecting frames 66 are connected to both ends of the clamping frame 63. By driving the second rotating shaft 65 to rotate through the motor, the second rotating shaft 65 drives the clamping frame 63 to rotate through the two connecting frames 66. A plurality of air holes (not shown in the figure) are also provided on the clamping frame 63. The air holes are communicated with an air extractor. When the air extractor operates, the air holes can have a negative pressure adsorption effect.

[0063] In this way, before the adhesive film on the unwinding roller 100 in the working state is about to be completely unwound, the worker can pull the adhesive film on the spare unwinding roller 100 onto the material receiving base 61. The clamping frame 63 can suck the spare adhesive film and clamp it together with the adhesive film unwound from the working unwinding roller 100 onto the heating block 62. The two groups of adhesive films are joined together under the action of the heating block 62. After joining, the new adhesive film can be fed together with the tail end of the adhesive film on the working unwinding roller 100, realizing seamless connection of the adhesive film and greatly improving the feeding efficiency.

[0064] In this embodiment, as shown in combination with Figure 5-6 the figure, the cutting assembly 3 includes two conveying rollers 31 arranged vertically and rotatably provided around their own axis directions respectively, and a second driving module 32 for driving one of the conveying rollers 31 to rotate. The two conveying rollers 31 are respectively parallel to the unwinding shaft 21. A conveying gap for the adhesive film to pass through is formed between the two conveying rollers 31. A cross-cutting unit 33 for cutting the adhesive film is provided on the side of the conveying gap away from the unwinding assembly 2.

[0065] The cross-cutting unit 33 includes a lower knife seat 331, a lower cutting knife 332 provided on the lower knife seat 331, an upper knife seat 333 that can be lifted and lowered above the lower knife seat 331, an upper cutting knife 334 provided on the upper knife seat 333, and a sixth driving module 335 for driving the upper knife seat 333 to lift and lower;

[0066] A pressure material module 336 is further provided on the upper tool holder 333. The pressure material module 336 includes a pressure material seat 3361, a guide rod 3362 slidably disposed in the pressure material seat 3361 along the vertical direction at the upper end, and a pressure material block 3363 disposed at the lower end of the guide rod 3362. A spring 3364 is sleeved on the guide rod 3362, and both ends of the spring 3364 are respectively connected to the pressure material seat 3361 and the pressure material block 3363. Among them, there are two pressure material seats 3361 and they are located at both ends of the upper tool holder 333. Correspondingly, there are also two guide rods 3362 and springs 3364 respectively. The lower ends of the two guide rods 3362 are respectively connected to both ends of the pressure material block 3363.

[0067] During cross-cutting, the sixth driving module 335 drives the upper tool holder 333 to descend. The pressure material block 3363 contacts the adhesive film and continuously presses against the adhesive film under the action of the spring 3364. During the descending process, the upper cutting knife 334 cooperates with the lower cutting knife 332 to realize cross-cutting of the adhesive film, effectively improving the cross-cutting quality.

[0068] In this embodiment, the sixth driving module 335 includes two rotating seats 3351 disposed on the frame 1 and located at both ends of the upper tool holder 333 respectively, a first rotating shaft 3352 with both ends rotatably connected to the two rotating seats 3351 respectively, and a driving member 3353 for driving the first rotating shaft 3352 to rotate.

Both ends of the first rotating shaft 3352 are respectively connected to the output ends of the two cams 3355. Among them, the driving member 3353 is a motor. The motor drives the first rotating shaft 3352 to rotate, and the first rotating shaft 3352 drives the two cams 3355 to rotate. The cam seats 3354 realize reciprocating lifting during the rotation of the cams 3355, so that the upper tool holder 333 can realize reciprocating lifting under the cooperation of the cams 3355 and the cam seats 3354, effectively improving the lifting stability of the upper tool holder 333.

[0069] In this embodiment, the cutting assembly 3 further includes a longitudinal cutting unit 34 disposed on one side of the conveying gap close to the unwinding assembly 2. The longitudinal cutting unit 34 includes a longitudinal cutting roller 341 and two longitudinal cutting modules 342 respectively disposed at both ends of the longitudinal cutting roller 341 and movably disposed along the length direction of the longitudinal cutting roller 341. A scale plate 343 is disposed on the side of the longitudinal cutting roller 341. The longitudinal cutting roller 341 and the scale plate 343 are both parallel to the conveying roller 31. Scales are respectively disposed at both ends of the scale plate 343, and the two groups of scales correspond to the two longitudinal cutting modules 342 one by one. Among them, the scale plate 343 is horizontally disposed and partially extends into the conveying gap, and it can assist in carrying the adhesive film to facilitate the smooth passage of the adhesive film through the conveying gap.

[0070] Each longitudinal cutting module 342 respectively includes a first longitudinal cutting base 3421, a longitudinal cutting groove 3422 circumferentially formed on the first longitudinal cutting base 3421, and a longitudinal cutting knife 3423. The cutting edge of the longitudinal cutting knife 3423 is embedded in the longitudinal cutting groove 3422.

[0071] When the adhesive film passes through the longitudinal cutting roller 341, the excess waste materials on both sides of it can be accurately cut off under the cooperation of the longitudinal cutting knife 3423 and the longitudinal cutting groove 3422, and the scale can indicate the cutting length of the waste materials. The position of the longitudinal cutting module 342 is adjusted according to different cutting lengths. Among them, the first longitudinal cutting base 3421 can slide on the longitudinal cutting roller 341 and is locked by bolts, while the longitudinal cutting knife 3423 is slidably sleeved on the mounting rod 344 through a second longitudinal cutting base 3424 and is locked by bolts. The mounting rod 344 is parallel to the longitudinal cutting roller 341.

[0072] In this embodiment, the adhesive film feeding mechanism further includes a buffer assembly 7 disposed between the unwinding assembly 2 and the cutting assembly 3. The buffer assembly 7 includes a buffer roller 71 that can be lifted and rotated about its own axis, and a seventh driving module 72 for driving the lifting of the buffer roller 71. The buffer roller 71 is parallel to the conveying roller 31. Among them, there are two seventh driving modules 72. Both of these two seventh driving modules 72 are structures of a motor and a belt and are respectively located at both ends of the buffer roller 71. The two ends of the buffer roller 71 are respectively connected to the belts of the two seventh driving modules 72. The belt pulley is driven by the motor to rotate, thereby driving the movement of the belt. The two belts drive the two ends of the buffer roller 71 to lift. A guide rail 73 extending in the vertical direction is further provided on the side of the belt. The two ends of the buffer roller 71 are slidably connected to the guide rail 73.

[0073] After the adhesive film is output from the feeding assembly 8, it first passes around the buffer roller 71 and then reaches the cutting assembly 3. The buffer roller 71 can cache and release the adhesive film passing around it through its own lifting, so as to provide sufficient working time for other processes under the continuous unwinding state of the unwinding roller 100, effectively improving the overall laying efficiency of the adhesive film.

[0074] In this embodiment, the adhesive film feeding mechanism further includes a plurality of guide rollers 9, and the plurality of guide rollers 9 are respectively disposed on the sides of the material receiving assembly 6 and the cutting assembly 3 for guiding the adhesive film during transportation.

[0075] The implementation principle of an adhesive film feeding mechanism according to an embodiment of the present application is as follows:

[0076] Place the working unwinding roller 100 on the feeding base 81, and then the eighth driving module 83 drives the feeding base 81 to rise. Then, the working unwinding roller 100 is installed on one of the mounting modules 23 through the clamping assembly 4 and the deviation rectifying assembly 5;

[0077] Place the spare unwind roller 100 on the loading seat 81. Subsequently, the eighth driving module 83 drives the loading seat 81 to rise. Then, install the spare unwind roller 100 on another installation module 23 through the clamping assembly 4 and the deviation rectifying assembly 5.

[0078] Unwind the adhesive film on the working unwind roller 100 outward. The unwound adhesive film is cut by the longitudinal cutting unit 34 and the transverse cutting unit 33 and then output outward.

[0079] Before the adhesive film on the working unwind roller 100 is about to be completely unwound, pull the adhesive film on the spare unwind roller 100 onto the receiving seat 61. The clamping frame 63 sucks the spare adhesive film and presses it together with the adhesive film unwound from the working unwind roller 100 onto the heating block 62. The two groups of adhesive films are joined together under the action of the heating block, and the spare adhesive film is unwound outward along with the tail end of the working adhesive film.

[0080] During the process of unwinding the adhesive film, the unwind shaft 21 rotates to realize the position conversion between the working unwind roller 100 and the spare unwind roller 100. When the adhesive film on the working unwind roller 100 is completely unwound, remove the working unwind roller 100. Then, replace the fully loaded unwind roller 100 and use it as the new spare unwind roller 100.

[0081] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
