[0021] like Figure 1-2As shown, the present invention discloses an automatic film laminating machine, including a material pulling mechanism 1, an air suction platform mechanism 2, a three-axis film taking / laminating mechanism 3, a coil stripping mechanism 4, and an X-axis translation module 5. The coil stripping mechanisms 4 are respectively installed on both sides of the air suction platform mechanism 2, and the three-axis film taking / laminating mechanism 3 is installed above the air suction platform mechanism 2. The material pulling mechanism 1 is installed at the front end of the air suction platform mechanism 2. The material pulling mechanism 1 is used to complete the pulling of the main material for a set distance, and the air suction platform mechanism 2 is used to suck the main material after the material pulling mechanism 1 completes the set distance pulling (to prevent the main material from moving). The X-axis translation module 5 is respectively connected to the material pulling mechanism 1 and the air suction platform mechanism 2, and the X-axis translation module 5 drives the material pulling mechanism 1 and the air suction platform mechanism 2 to translate to the film laminating position; the coil stripping mechanism 4 is used to separate the coil protective film from the base paper on the coil protective film, and the three-axis film taking / laminating mechanism 3 moves to suck the main material after the material pulling mechanism 1 completes the set distance pulling. After separating the protective film of the roll material from the backing paper, the sucked protective film of the roll material is moved to the film pasting position for laminating with the main material which is moved to the film pasting position at the same time.

[0022] The material pulling mechanism 1 includes a driving device and a material pulling roller. The driving device drives the material pulling roller to rotate, thereby realizing roll-to-roll pulling of the main material.

[0023] like Figure 4-5 As shown, the three-axis film taking / laminating mechanism 3 includes a suction mechanism 30 and a moving mechanism. The moving mechanism is connected to the suction mechanism 30. The moving mechanism drives the suction mechanism 30 to move and absorb the roll material protective film. The suction mechanism 30 is responsible for laminating the sucked roll material protective film with the main material.

[0024] The moving mechanism includes a Y-axis translation module 31 , and the Y-axis translation module 31 is connected to the suction mechanism 30 . The Y-axis translation module 31 includes a first driving device and a first screw rod. The first driving device drives the first screw rod to translate the suction mechanism 30 .

[0025] The moving mechanism includes a Z-axis lifting module 32 , which is connected to the suction mechanism 30 . The Z-axis lifting module 32 includes a second driving device and a second screw rod. The second driving device drives the second screw rod to lift the suction mechanism 30 .

[0026] The moving mechanism includes a C-axis rotating module 33 , and the C-axis rotating module 33 is connected to the suction mechanism 30 . The C-axis rotating module 33 includes a third driving device, and the third driving device drives the suction mechanism 30 to rotate.

[0027] The driving device, the first driving device, the second driving device and the third driving device are servo motors.

[0028] The three-axis film taking / sticking mechanism 3 includes a fixed bracket 34 , on which the suction mechanism 30 and the moving mechanism are respectively mounted, and the suction mechanism 30 is located at both ends of the fixed bracket 34 .

[0029] The suction mechanism 30 includes a vacuum solenoid valve 330, a vacuum suction plate 340, a lifting cylinder 310, and a rubber wheel 320. The rubber wheel 320 is installed on the vacuum suction plate 340. The vacuum suction plate 340 is connected to the vacuum solenoid valve 330. The vacuum solenoid valve 330 controls the vacuum suction plate 340 to suck the roll material protective film separated by the roll material stripping machine 4. The rubber wheel 320 is connected to the lifting cylinder 310. The lifting cylinder 310 pushes the rubber wheel 320 downward to achieve partial bonding between the main material and the roll material protective film, and then moves through the X-axis translation module 5 or the Y-axis translation module 31 to achieve rolling bonding.

[0030] The X-axis translation module 5 includes a fourth driving device and a fourth screw rod. The fourth driving device drives the screw rod to drive the material pulling mechanism 1 and the air suction platform mechanism 2 to translate to the film pasting position; the fourth driving device is a servo motor.

[0031] like Figure 6-7 As shown, the roll material stripping mechanism 4 includes a roll material protective film discharge position 40, a rotating pulling roller 42, and a stripping blade 44. The roll material protective film discharge position 40 is used to place and pull the roll material protective film and provide tension control for the pulled roll material protective film. The rotating pulling roller 42 separates the base paper on the roll material protective film from the roll material protective film by rotating and pulling. After the base paper of the roll material protective film is separated from the roll material protective film by the rotating pulling roller 42, the base paper is recovered by the follow-up rotating air shaft 45. The roll material protective film with the base paper stripped off moves to the stripping blade 44 driven by the rotating pulling roller 42, and the stripping blade 44 cuts the roll material protective film.

[0032] The coil protective film discharge place 40 includes a rotating air shaft and a tension motor. The tension motor is connected to the rotating air shaft. The coil protective film is installed on the rotating air shaft. The tension motor provides a certain tension when controlling the coil protective film to be pulled.

[0033] The web stripping mechanism 4 comprises a threading follower roller 41, and the threading follower roller 41 is used to ensure that the tension of the web protective film is constant when being pulled.

[0034] The web stripping mechanism 4 includes a follower rotating air shaft 45, and the follower rotating air shaft 45 is used to recycle the base paper.

[0035] The web stripping mechanism 4 includes an optical fiber sensor 43 . The optical fiber sensor 43 is installed below the stripping blade 44 . The optical fiber sensor 43 is used to sense the initial position of the web protective film after being cut by the stripping blade 44 .

[0036] The coil stripping mechanism 4 is provided with a first positioning mechanism, and the first positioning mechanism is used to obtain the position coordinates of the coil protective film.

[0037] The first positioning mechanism includes a first camera 8 , and the first cameras 8 are respectively installed near the left and right sides of the stripping edge 44 .

[0038] The automatic film laminating machine further comprises a second positioning mechanism, which is connected to the X-axis translation module 5 and is used to obtain the position of the main material positioning hole.

[0039] like Figure 3 As shown, the second positioning mechanism includes a second camera 6. The second camera 6 is installed below the suction platform mechanism 2. There are two second cameras 6, and the position of the second camera 6 is adjustable. The second camera 6 is used to photograph the main material positioning hole, accurately confirm the position of the printed content on the main material (Note: the position of the second camera is adjustable according to the different positions of the main material positioning holes), and obtain the film-sticking coordinates.

[0040] The working process of an automatic film laminating machine of the present invention is as follows:

[0041] Step 1: The main material is pulled at a set distance; the main material is pulled at a set distance through the pulling mechanism 1.

[0042] Step 2: The suction platform mechanism 2 sucks the main material after the pulling mechanism 1 completes pulling for a set distance.

[0043] Step 3: The two second cameras 6 installed below the air suction platform mechanism 2 take photos of the main material positioning holes respectively to obtain the main material film pasting coordinates.

[0044] Step 4: The X-axis translation module 5 drives the material pulling mechanism 1, the air suction platform mechanism 2, and the second positioning mechanism to translate to the film pasting position. At this time, the roll material protective film after the base paper is separated by the roll material peeling mechanism 4 is also moved to the film pasting position (the three-axis taking / film pasting mechanism 3 drives the suction mechanisms 7 at both ends to move and absorb the roll material protective film after the base paper is separated by the roll material peeling mechanism 4), and then the lifting cylinder 310 on the roll material peeling mechanism 4 pushes the rubber wheel 320 downward to realize partial bonding of the main material and the roll material protective film.

[0045] In step 4, the web peeling mechanism 4 is used to separate the web protective film from the backing paper on the web protective film. The specific process is as follows:

[0046] The roll material protective film is controlled by the tension of the tension motor on the roll material stripping mechanism 4 and is pulled by the rotating pulling roller 42. The base paper on the roll material protective film is pulled by rotation to separate it from the roll material protective film. The roll material protective film with the base paper stripped off is driven by the rotating pulling roller 42 and moves to the stripping edge 44 through the feeding follower roller 41. The stripping edge 44 cuts the roll material protective film (separating the base paper and the roll material protective film in the stripping edge). The optical fiber sensor 43 senses the initial position of the roll material protective film after being cut by the stripping edge 44.

[0047] Step 5: Move the X-axis translation module 5 or the Y-axis translation module 31 to achieve rolling of the coiled material protective film and the main material.

[0048] The automatic laminating machine workflow also includes the bottom paper recycling step:

[0049] The bottom paper is recovered by the follow-up rotating air shaft 45 through rotation. (Note: After the roll material protective film is sucked by the suction mechanism 7, the bottom paper needs to be discarded)

[0050] The automatic film sticking machine of the present invention refers to the film material with adhesiveness, including but not limited to the protective film with adhesiveness, double-sided self-adhesive film, single-sided self-adhesive film and the like.

[0051] The beneficial effects of the present invention are: 1. The automatic film laminating machine of the present invention can accurately locate the position coordinates of the main material and the roll material protective film, so that the main material and the roll material protective film can be more accurately laminated; 2. The automatic film laminating machine of the present invention can automatically separate the roll material protective film and the base paper; 3. The positioning mechanism of the automatic film laminating machine of the present invention can be adjusted according to the different positions of the positioning holes, and the flexibility is stronger; 4. The automatic film laminating machine of the present invention can drive the mold suction mechanism to perform translation, lifting and rotation movements, and the operation is more convenient.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
