With the development of fine operations, the quality requirements for cameras on mobile phones, automobiles, computers, etc. are getting higher and higher. When the camera leaves the factory, a protective film needs to be pasted on the camera for protection. As the processing requirements for cameras are getting higher and higher, the requirements for some die-cutting protection materials by major camera manufacturers are also getting higher and higher. For example, the concentricity needs to be guaranteed within 0.1 mm after the lens protection cover and the plastic film are laminated; there should be no appearance defects such as scratches, dirt, foreign objects, and poor lamination on the product surface. Moreover, the camera protective film is a one-time consumable with a very large usage volume. It is very difficult to meet the customer's requirements without a complete and high-quality lamination process. The lamination of the lens protection cover and the plastic film mostly uses a manual lamination method. In the prior art, the problem of the unguaranteed quality of manual lamination products is solved by setting up a lamination device. However, the lamination device in the prior art has the following problems. After the protection cover and the plastic film are fixed by the lamination device in the prior art and then laminated, the plastic film is prone to dislocation or deviation during the lamination process, resulting in inaccurate lamination on the protection cover and usually not meeting the 0.1 mm accuracy requirement.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] As Figure 1 shown, the present invention provides a plastic film laminating device for a mobile phone lens protection cover, which respectively fixes the protection cover and the plastic film, and fixes the protection cover in a specific orientation, adjusts the position and angle of the plastic film according to the position of the protection cover to be adapted to the protection cover, and ensures the accuracy of the lamination of the protection cover and the plastic film.

[0045] The present invention includes a fixed base 1, a bracket 2, a mounting top frame 3, a fixing mechanism 4, and an adjusting mechanism 5. The fixing mechanism 4 is arranged on the fixed base 1, and the adjusting mechanism 5 is arranged on the mounting top frame 3. The fixed base 1 is connected to the mounting top frame 3 through the bracket 2. The fixing mechanism 4 fixes the protective cover in a specific orientation and adjusts the protective cover to be horizontal. The adjusting mechanism 5 transports and clamps the plastic film and adjusts the position of the plastic film according to the position of the protective cover to align with the protective cover.

[0046] The fixing mechanism 4 in the present invention includes a translational clamping assembly 41 and a pressing-down assembly 42 arranged on the fixed base 1. The translational clamping assembly 41 pushes the protective cover to a fixed position, and the pressing-down assembly 42 presses down the protective cover to be horizontally placed inside the translational clamping assembly 41 under the action of the translational clamping assembly 41. At first, the protective cover is placed on the translational clamping assembly 41 in a general situation of the standard position, and then it is gradually adjusted to the specified position state under the push of the translational clamping assembly 41. During the pushing process, the protective cover may tilt. Therefore, in this embodiment, the pressing-down assembly 42 is designed to press down the protective cover to a horizontal state.

[0047] An installation groove 6 for installing the translational clamping assembly 41 is arranged on the fixed base 1. The translational clamping assembly 41 mainly adopts the following preferred embodiment. The translational clamping assembly 41 includes a fixed groove seat 411 arranged in the installation groove 6, two pairs of relatively sliding sliding side plates 412 arranged in the fixed groove seat 411, a threaded driving rod 413 threadedly connected to the sliding side plates 412, and a first driving motor 414 connected to the threaded driving rod 413. The sliding side plates 412 are parallel to the side of the fixed groove seat 411. The first driving motor 414 drives the threaded driving rod 413 to rotate, and a sliding groove 415 for the sliding side plates 412 to slide is arranged on the fixed groove seat 411.

[0048] The rotation of the first driving motor 414 drives the threaded driving rod 413 to rotate. The sliding side plates 412 slide inwards or outwards under the rotation of the threaded driving rod 413, and the protective cover is pushed to a specific position. In this embodiment, a driving cylinder can also be used to drive the sliding side plates to displace.

[0049] During the process of pushing the protective cover to a specific position, the pressing-down assembly 42 is used to press the protective cover to a horizontal position. The pressing-down assembly 42 mainly adopts the following preferred embodiment. The pressing-down assembly 42 includes a worm 421 rotatably arranged in the sliding side plate 412 and a worm gear 422 meshed with the worm 421. One end of the worm 421 away from the sliding side plate 412 penetrates into the fixed groove seat 411 and is connected with a second driving motor 423. A rotating shaft column 424 is connected to the worm gear 422, and an L-shaped pressing plate 425 is connected to the rotating shaft column 424. The worm gear 422 drives the L-shaped pressing plate 425 through the rotating shaft column 424 to press down the protective cover to a horizontal state.

[0050] During the operation of the translation clamping assembly 41, the second drive motor 423 rotates to drive the worm 421 to rotate, thereby driving the worm gear 422 to rotate. The worm gear 422 drives the L-shaped lower pressing plate 425 to rotate counterclockwise through the rotating shaft column 424 to exert a downward pressing force on the protective cover. In this embodiment, the left end of the worm 421 is always clamped and rotatably arranged in the sliding side plate 412. That is to say, when the sliding side plate 412 displaces, it drives the second drive motor 423 on the right side to displace together. Therefore, sliding grooves for the worm 421 and the second drive motor 423 are provided on both the fixed base 1 and the fixed groove seat 411.

[0051] The present invention uses the position adjustment mechanism 5 to adjust the angular position of the plastic film. The position adjustment mechanism 5 includes a clamping adjustment component 51, a conveying component 52, a transfer printing component 53, and a monitoring component 54 arranged on the installation top frame 3. The conveying component 52 conveys the plastic film directly above the fixing mechanism 4. The transfer printing component 53 prints cross positioning marks on the plastic film during the conveying process of the conveying component 52 for the plastic film. The monitoring component 54 is used to monitor the cross positioning marks on the plastic film in the length and width directions of the protective cover. The clamping adjustment component 51 continuously adjusts the angle and position of the plastic film according to the real-time monitoring results of the monitoring component 54.

[0052] In this embodiment, the conveying component 52 adopts the conveying method of the prior art, and only fixes the plastic film during the conveying process so that the transfer printing component 53 transfers to a specific position on the plastic film. The conveying component 52 includes conveying rollers 521 arranged at both ends of the installation top frame 3 and a conveying belt 522 arranged on the conveying rollers 521. Positioning blocks 523 for temporarily fixing the plastic film are arranged on the conveying belt 522. The positioning blocks 523 are in contact with the four side edges of the plastic film. Perforations 524 for the clamping adjustment component 51 to drive the plastic film to press through are equidistantly arranged on the conveying belt 522. And the conveying component 52 in this embodiment is periodically and regularly conveyed, and is conveyed every once in a while to facilitate the transfer printing and fitting.

[0053] The transfer printing component 53 in the present invention also uses a printing device of the prior art to print. The transfer printing component 53 prints cross positioning marks and a center mark on the plastic film. The center mark is arranged at the center position of the cross positioning marks. The transfer printing component 53 of the present invention mainly uses an ink that is easy to clean for printing to facilitate the later cleaning of the added cross positioning marks and center marks, or directly uses an ink that will volatilize within a certain period of time for printing. However, this design requires strict control of the volatilization time of the ink and monitoring to avoid the situation that the monitoring component 54 cannot monitor the cross positioning marks and center marks due to the volatilization of the ink during the monitoring process.

[0054] The monitoring component 54 in this embodiment mainly adopts the following preferred embodiments. The monitoring component 54 includes a central monitoring sensor 541, a lateral monitoring sensor 542, a longitudinal monitoring sensor 543, and a data processing unit 544 arranged on the installation top frame 3. The lateral monitoring sensor 542 is correspondingly arranged at one end in the length direction of the central position of the protective cover, and the longitudinal monitoring sensor 543 is correspondingly arranged at one end in the width direction of the central position of the protective cover. The central monitoring sensor 541 monitors the central mark in the same vertical direction, the lateral monitoring sensor 542 monitors the lateral end of the cross positioning mark in the vertical direction, and the longitudinal monitoring sensor 543 monitors the longitudinal end of the cross positioning mark in the vertical direction. In this embodiment, the central monitoring sensor 541 monitors whether the position of the plastic film deviates and continuously monitors during the process of adjusting the deviation until the adjustment is completed. The lateral monitoring sensor 542 and the longitudinal monitoring sensor 543 monitor whether the plastic film has an angular deviation and continuously monitor in real time during the process of adjusting the angle until the adjustment is completed.

[0055] The central monitoring sensor 541, the lateral monitoring sensor 542, and the longitudinal monitoring sensor 543 proposed in this embodiment are used to monitor the cross positioning mark and the central mark. Therefore, sensors for detecting colors can be used to detect the cross positioning mark and the central mark.

[0056] The data processing unit 544 in this embodiment is communicatively connected to the central monitoring sensor 541, the lateral monitoring sensor 542, and the longitudinal monitoring sensor 543. That is to say, the data processing unit 544 receives the real-time monitoring data of the central monitoring sensor 541, the lateral monitoring sensor 542, and the longitudinal monitoring sensor 543.

[0057] The data processing unit 544 stores standard data corresponding to the central monitoring sensor 541, the lateral monitoring sensor 542, and the longitudinal monitoring sensor 543 when the plastic film is arranged at the specified position below the monitoring component 54. The data processing unit 544 receives the real-time monitoring data of the central monitoring sensor 541 and compares it with the standard data. The clamping adjustment component 51 translates according to the comparison result. The data processing unit 544 receives the real-time monitoring value of the lateral monitoring sensor 542 and conducts a first comparison with the standard data. When the comparison is consistent, the real-time monitoring data of the longitudinal monitoring sensor 543 is compared with the standard data for the second time. The clamping adjustment component 51 adjusts the angle of the plastic film according to the result of the first comparison.

[0058] In the present invention, the clamping adjustment component 51 is usually used to adsorb and move the plastic film upward to monitor it through the monitoring component 54. The completion of the upward movement of the clamping adjustment component 51 can be used as the monitoring start signal of the detection component 54.

[0059] The specific operation of the monitoring component 54 is as follows. First, the central monitoring sensor 541 monitors whether the central mark is in the specified position, and transmits the real-time monitoring data to the data processing unit 544 for data comparison. Through continuous adjustment of the clamping and adjusting component 51 and continuous comparison of the real-time monitoring data, the central mark is shifted to a specific position. Then, the lateral monitoring sensor 542 monitors whether the cross positioning mark is in the specified position, and transmits the real-time monitoring data to the data processing unit 544 for data comparison. Through continuous adjustment of the angle of the clamping and adjusting component 51 and continuous comparison of the real-time monitoring data, the plastic film is adjusted to a specific position, and the longitudinal monitoring sensor 543 is used for secondary comparison to verify that the plastic film has indeed been moved to the specific position. When the comparison results of the real-time monitoring data of the lateral monitoring sensor 542 and the longitudinal monitoring sensor 543 are different, it is necessary to check the internal structure of the detection component 54 and the cross positioning mark and the central mark on the plastic film, and replace the corresponding device in case of a detected fault.

[0060] The present invention mainly uses the clamping and adjusting component 51 to adjust the position and angle of the plastic film. The clamping and adjusting component 51 includes a translation frame base 511 provided on the installation top frame 3, a rotating disk 512 provided in the translation frame base 511, a translation member 513 provided on the side of the translation frame base 511, and a rotating member 514 connected to the side of the rotating disk 512. A pushing cylinder 515 is connected below the rotating disk 512, a suction cup 516 is connected below the pushing cylinder 515, and the upper end of the suction cup 516 is connected to an air extraction pump 518 through an air extraction pipe 517. The suction cup 516 adsorbs the four corners of the plastic film and controls the displacement of the plastic film. The clamping and adjusting component 51 also fixes the plastic film. The air extraction pump 518 extracts the gas inside the suction cup 516 to make the suction cup 516 adsorb on the plastic film.

[0061] In this embodiment, the translation member 513 drives the translation frame base 511 to translate to adjust the horizontal position of the translation frame base 511, and the rotating member 514 drives the rotating disk 512 to rotate to adjust the angle of the rotating disk 512.

[0062] The translation member 513 mainly uses an adjusting cylinder 5131 provided on the installation top frame 3. The adjusting cylinders 5131 are respectively connected to the four sides of the translation frame base 511. The adjusting cylinder 5131 drives the translation frame base 511 to move to adjust the horizontal position of the translation frame base 511. By adjusting the adjusting cylinders 5131 on the adjacent sides, the position of the translation frame base 511 can be adjusted.

[0063] In this embodiment, a rotating member 514 is used to adjust the angle of the plastic film. The rotating member 514 includes a connecting bolt 5141 connected to a rotating disk 512, a gear arc plate 5142 connected to the connecting bolt 5141, and an adjusting gear 5143 meshing with the outer side of the gear arc plate 5142. An arc-shaped hole for the connecting bolt 5141 to pass through is provided on a translation frame base 511, and a sliding ring groove 5144 for the gear arc plate 5142 and the adjusting gear 5143 to slide and be placed is provided on the translation frame base 511. A third driving motor is connected to the adjusting gear 5143, and the third driving motor drives the adjusting gear 5143 to rotate.

[0064] The third driving motor drives the adjusting gear 5143 to rotate, thereby driving the gear arc plate 5142 to rotate. The gear arc plate 5142 drives the rotating disk 512 to rotate through the connecting bolt 5141, thereby driving the plastic film at the lower end to rotate.

[0065] In summary, the main implementation manners of the present invention are as follows. The protective cover is fixed at a specific position through a fixing mechanism 4. A conveying assembly 52 is used to transport the plastic film, and it is transported to the lower part of a transfer assembly 53 for printing a cross positioning mark and a center mark. When it is transported to the lower part of a clamping and adjusting assembly 51, the clamping and adjusting assembly 51 adsorbs the plastic film and moves it for a certain distance. The center mark is monitored through a monitoring assembly 54. According to the monitoring result, the translation member 513 is controlled to drive the plastic film to move to a specific position, and then the cross positioning mark is monitored. According to the monitoring result, the rotating member 514 is controlled to adjust the plastic film to rotate by a certain angle to a specific angle. After the adjustment is completed, the plastic film is driven to move down and fit on the protective cover and left standing for a period of time. Then, the plastic film is driven to the conveying assembly 52 by the clamping and adjusting assembly 51 and conveyed out.
