[0034] This utility model embodiment provides a protective film application device for MNT products, see reference. Figures 1 to 8 The protective film applicator mainly includes a support frame 1, a flip-up MNT feeding mechanism 2, a protective film feeding mechanism 3, a first visual positioning component 4, and a second visual positioning component 5. The support frame 1 is also covered by an upper housing 8, and the support frame 1, the flip-up MNT feeding mechanism 2, the protective film feeding mechanism 3, the first visual positioning component 4, and the second visual positioning component 5 are housed within the upper housing 8.

[0035] The MNT loading mechanism 2 is connected to the first end of the support frame 1 and is used to carry and hold the MNT product 7. The protective film loading mechanism 3 is connected to the second end of the support frame 1 and is movable to the opposite side of the MNT loading mechanism 2, and is used to carry and hold the protective film 6. The first visual positioning component 4 is connected to the support frame 1 and is used to visually position the protective film 6 loaded on the protective film loading mechanism 3. The second visual positioning component 5 is connected to the protective film loading mechanism 3 and is movable with the protective film loading mechanism 3, and is used to visually position the MNT product 7 loaded on the MNT loading mechanism 2.

[0036] The protective film feeding mechanism 3 includes a displacement drive assembly 31 and a protective film support platform 32 and a roller 33, which are respectively vertically and flexibly connected to the displacement drive assembly 31. The protective film support platform 32 is a vacuum adsorption platform, and the protective film 6 is fed onto the protective film support platform 32 and adsorbed and fixed. After the protective film feeding mechanism 3 loads the protective film 6 and moves to a position relatively below the MNT feeding mechanism 2, the protective film support platform 32 is used to press and attach the protective film 6 onto the MNT product 7, and the roller 33 is used to roll and press the attached protective film 6.

[0037] As a specific solution, in this embodiment, such as Figure 3 The MNT loading mechanism 2 includes a first support 21, a rotating shaft 22, a servo motor 23, and an MNT carrier platform 24. The first support 21 is connected to the support frame 1, the rotating shaft 22 is rotatably connected to the first support 21, one end of the rotating shaft 22 is connected to the output end of the servo motor 23, and the MNT carrier platform 24 is connected to the rotating shaft 22. The MNT carrier platform 24 is a vacuum adsorption platform. The MNT product 7 is loaded onto the MNT carrier platform 24 and adsorbed and fixed. The servo motor 23 drives the rotating shaft 22 to rotate, thereby rotating the MNT carrier platform 24 and enabling the MNT product 7 to be flipped.

[0038] In this embodiment, the displacement drive assembly 31 includes a first linear drive module 31a and a UVW platform 31b. The first linear drive module 31a extends to the lower side of the MNT loading mechanism 2. The UVW platform 31b is movably connected to the first linear drive module 31a. The protective film support platform 32 is connected to the UVW platform 31b via a first lifting mechanism 34, and the roller 33 is connected to the UVW platform 31b via a second lifting mechanism 35. The first linear drive module 31a can drive the UVW platform 31b to move closer to or away from the MNT loading mechanism 2, thereby causing the protective film support platform 32 to move closer to or away from the MNT loading mechanism 2.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the first linear drive module 31a includes a cylinder 311, a lead screw 312, a sliding seat 313, and a guide rail 314. The lead screw 312 is connected to the output end of the cylinder 311, and the sliding seat 313 is connected to the lead screw 312 and slidably connected to the guide rail 314. The guide rail 314 extends to the lower part of the MNT loading mechanism 2. The UVW platform 31b is connected to the sliding seat 313. The cylinder 311 drives the sliding seat 313 to move along the guide rail 314 via the lead screw 312, thereby causing the UVW platform 31b connected to the sliding seat 313 to move closer to or away from the MNT loading mechanism 2.

[0040] In this embodiment, the first end of the protective film support platform 32 is rotatably connected to the UVW platform 31b via a rotating assembly 36, the inner bottom surface of the second end of the protective film support platform 32 is connected to the UVW platform 31b via the first lifting mechanism 34, and the roller 33 is connected to the UVW platform 31b via the second lifting mechanism 35 on the outer side adjacent to the second end of the protective film support platform 32. After the protective film feeding mechanism 3 loads the protective film 6 and moves to a position relatively below the MNT feeding mechanism 2: First, the first lifting mechanism 34 drives the second end of the protective film support platform 32 to rise, pressing the protective film 6 against the MNT product 7; then, the second lifting mechanism 35 drives the roller 33 to rise, pressing against the protective film 6 attached to the MNT product 7; further, the protective film feeding mechanism 3 is driven to move away from the MNT feeding mechanism 2, and the roller 33 rolls and presses against the attached protective film 6 as it moves, making the protective film 6 adhere more tightly to the MNT product 7.

[0041] The first lifting mechanism 34 and the second lifting mechanism 35 are preferably lifting cylinders.

[0042] Since the first end of the protective film carrier platform 32 is rotatably connected to the UVW platform 31b via the rotating assembly 36, when the first lifting mechanism 34 drives the second end of the protective film carrier platform 32 to rise, the protective film carrier platform 32 is tilted, which makes it easier to press and attach the protective film 6. Furthermore, since the second end of the protective film carrier platform 32 is higher than the first end, it can prevent the first end of the protective film carrier platform 32 from scraping the MNT product 7 connected to the MNT feeding mechanism 2 when the protective film feeding mechanism 3 exits from below the MNT feeding mechanism 2.

[0043] Furthermore, a buffer structure 37 is connected to the UVW platform 31b corresponding to the middle of the protective film support platform 32, and the buffer structure 37 abuts against the bottom surface of the protective film support platform 32. The buffer structure 37 is used to buffer the descent process of the protective film support platform 32 to avoid damage from excessively violent descent.

[0044] As a preferred embodiment, see [reference]. Figure 5 and Figure 6 An auxiliary platform 38, which is flush with the protective film support platform 32, is provided on the outer side of the second end of the protective film support platform 32. The auxiliary platform 38 is connected to the UVW platform 31b through a second linear drive module 39. The auxiliary platform 38 can slide above the roller 33 and abut against the second end of the protective film support platform 32 through the second linear drive module 39. When the protective film 6 is loaded on the protective film support platform 32, one end of the protective film 6 extends from the second end of the protective film support platform 32 and is connected to the auxiliary platform 38.

[0045] After the protective film loading mechanism 3 loads the protective film 6 and moves to a position relatively below the MNT loading mechanism 2: First, the second linear drive module 39 drives the auxiliary platform 38 to move toward the second end away from the protective film support platform 32, exposing the roller 33 below it, and the portion of the protective film 6 originally connected to the auxiliary platform 38 is located directly above the roller 33; then, the first lifting mechanism 34 drives the second end of the protective film support platform 32 to rise, pressing the protective film 6 against the MNT product 7; further, the second lifting mechanism 35 drives the roller 33 to rise and press against the protective film 6.

[0046] In the specific embodiment, the output end of the second lifting mechanism 35 is connected to a roller fixing seat 33a, and the roller 33 is rotatably connected in the roller fixing seat 33a. The second lifting mechanism 35 drives the roller fixing seat 33a to rise and fall, thereby causing the roller 33 to rise or fall.

[0047] As a specific solution, in this embodiment, combined with Figure 3 and Figure 7 As shown, the first visual positioning component 4 includes a second bracket 41, a third linear drive module 42, a first CCD camera 43, and a second CCD camera 44. The second bracket 41 is connected to the support frame 1 and located between the MNT loading mechanism 2 and the protective film loading mechanism 3. The third linear drive module 42 is connected to the second bracket 41. The first CCD camera 43 is connected to the second bracket 41 at a first end adjacent to the third linear drive module 42. The second CCD camera 44 is movably connected to the third linear drive module 42. The lenses of the first CCD camera 43 and the second CCD camera 44 face downwards and are higher than the upper surface of the protective film loading mechanism 3.

[0048] The third linear drive module 42 is arranged in a direction perpendicular to the first linear drive module 31a. When the protective film loading mechanism 3 loads the protective film 6 and moves towards the MNT loading mechanism 2 to below the first visual positioning component 4, the first visual positioning component 4 positions the protective film 6 on the protective film loading mechanism 3 using image information acquired by the first CCD camera 43 and the second CCD camera 44.

[0049] As a specific solution, in this embodiment, combined with Figure 3 and Figure 8 As shown, the second visual positioning component 5 includes a third bracket 51, a fourth linear drive module 52, a third CCD camera 53, and a fourth CCD camera 54. The third bracket 51 is connected to the end of the protective film feeding mechanism 3 facing the MNT feeding mechanism 2, specifically to the sliding seat 313 in the protective film feeding mechanism 3. The fourth linear drive module 52 is connected to the third bracket 51. The third CCD camera 53 is connected to the third bracket 51 at its first end adjacent to the fourth linear drive module 52, and the fourth CCD camera 54 is movably connected to the fourth linear drive module 52. The lenses of the third CCD camera 53 and the fourth CCD camera 54 face upwards and are below the lower surface of the MNT feeding mechanism 2.

[0050] The fourth linear drive module 52 is arranged in a direction perpendicular to the first linear drive module 31a. When the protective film loading mechanism 3 loads the protective film 6 and moves to a position relatively below the MNT loading mechanism 2, the second visual positioning component 5 moves accordingly to a position relatively below the MNT loading mechanism 2. The second visual positioning component 5 uses image information acquired by the third CCD camera 53 and the fourth CCD camera 54 to position the MNT product 7 on the MNT loading mechanism 2.

[0051] The protective film application device provided in the above embodiment includes the following steps in its application operation of applying the protective film to the MNT product:

[0052] S1. The MNT product 7 is fed onto the MNT carrier platform 24 of the MNT feeding mechanism 2 with the film surface facing upward and is fixed by adsorption. The MNT carrier platform 24 is driven to rotate by the servo motor 23, so that the MNT product 7 is flipped so that the film surface faces downward.

[0053] S2. The protective film 6 is fed onto the protective film support platform 32 of the protective film feeding mechanism 3 with the adhesive side facing upward and is adsorbed and fixed. The first linear drive module 31a drives the protective film feeding mechanism 3 to move toward the MNT feeding mechanism 2.

[0054] S3. When the protective film feeding mechanism 3 moves below the first visual positioning component 4, the first visual positioning component 4 positions the protective film 6 on the protective film carrier platform 32 using the image information obtained by the first CCD camera 43 and the second CCD camera 44.

[0055] S4. The protective film feeding mechanism 3 continues to move toward the MNT feeding mechanism 2. When the second visual positioning component 5 connected to the protective film feeding mechanism 3 moves below the MNT feeding mechanism 2, the second visual positioning component 5 positions the MNT product 7 on the MNT carrier platform 24 using the image information obtained by the third CCD camera 53 and the fourth CCD camera 54.

[0056] S5. Based on the positioning information obtained in steps S3 and S4, the specific position of the protective film carrier platform 32 is adjusted by the UVW platform 31b so that the MNT product 7 on the MNT carrier platform 24 and the protective film 6 on the protective film carrier platform 32 are precisely aligned.

[0057] S6. The second linear drive module 39 drives the auxiliary platform 38 to move toward the second end away from the protective film support platform 32, exposing the roller 33 below it, so that the part of the protective film 6 originally connected to the auxiliary platform 38 is directly above the roller 33.

[0058] S7. The second end of the protective film support platform 32 is raised by the first lifting mechanism 34, and one end of the protective film 6 is pressed and attached to the MNT product 7.

[0059] S8. The roller 33 is driven to rise by the second lifting mechanism 35 and presses against the protective film 6 attached to the MNT product 7.

[0060] S9. Drive the protective film feeding mechanism 3 to move away from the MNT feeding mechanism 2. The roller 33 rolls and presses against the attached protective film 6 as it moves, so that the protective film 6 is tightly attached to the MNT product 7.

[0061] S10. When the protective film carrier platform 32 retracts to the second end of the support frame 1, the second lifting mechanism 35 drives the roller 33 to descend, the first lifting mechanism 34 drives the second end of the protective film carrier platform 32 to descend, the second linear drive module 39 drives the auxiliary carrier platform 38 to abut against the second end of the protective film carrier platform 32, and the servo motor 23 drives the MNT carrier platform 24 to rotate so that the MNT product 7 after film application flips to have the film surface facing upward, thereby completing this round of film application and waiting for the next round of film application.

[0062] In summary, the protective film applicator for MNT products provided in this embodiment of the present invention, by setting up a corresponding MNT feeding mechanism and a protective film feeding mechanism and configuring a corresponding visual positioning component, allows the visual positioning component to accurately visually position the protective film loaded on the protective film feeding mechanism and the MNT product loaded on the MNT feeding mechanism. Then, the protective film feeding mechanism presses and applies the protective film onto the MNT product. Through automated equipment, the protective film is applied to the MNT product quickly, accurately, and stably, improving work efficiency and saving labor costs.

[0063] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
