Description

Technical Field

[0001] This application relates to the technical field of acrylic processing equipment, and specifically relates to a precise film feeding and positioning device. Background Art

[0002] After acrylic is laser cut, it is necessary to assist in laminating the finished product when taking out the finished product. The current laminating operation requires manually attaching a sticky film to the acrylic to stick together the scattered parts for easy overall removal.

[0003] This process is fully manual. Currently, the weight of a complete roll of film is about 5KG, and the speed of the laser cutting machine is about one board every 14 minutes. That is to say, every 14 minutes, the worker has to manually pick up the film roll for laminating and also align it. This greatly increases the working intensity, and the laminating is prone to position deviation, which is not conducive to improving efficiency. Utility Model Content

[0004] Therefore, this application provides a precise film feeding and positioning device to solve the problems in the prior art that manually handling the film roll for laminating affects the laminating effect and has too high labor intensity.

[0005] To achieve the above purpose, this application provides the following technical solutions:

[0006] A precise film feeding and positioning device includes a vertical rod. A rotary cylinder is installed at the top of the vertical rod. The rotating shaft at the driving end of the rotary cylinder is horizontal and perpendicular to the vertical rod. A bracket is installed at the driving end to drive the bracket to rotate. A guide rail is installed on the bracket. A slider is engaged with the guide rail, and the sliding direction of the slider is perpendicular to the vertical rod. A smooth shaft for fixing the film roll is installed on the slider. The film roll can rotate relative to the smooth shaft, and a positioning member for preventing the film roll from falling is also provided on the smooth shaft.

[0007] Optionally, a bearing seat is provided between the slider and the smooth shaft. The bearing seat is fixed on the slider, and the smooth shaft is installed on the bearing seat.

[0008] Optionally, the positioning member includes a first fixing block and a second fixing block. The first fixing block is fixed at one end of the smooth shaft close to the bearing seat. The second fixing block is movably inserted through the smooth shaft and can slide out from the other end of the smooth shaft.

[0009] Optionally, a housing for sleeving outside the film roll is also fixed on the smooth shaft. An opening for the film to pass through is axially formed on the peripheral wall of the housing.

[0010] Optionally, a limit stop block for preventing the slider from sliding out is provided at the end of the guide rail.

[0011] Optionally, the rotary cylinder is mounted on the top of the vertical rod through a mounting base, and an angle code is connected between the mounting base and the vertical rod.

[0012] Optionally, the vertical rod is made of aluminum profile.

[0013] Optionally, a base is provided at the bottom of the vertical rod, and a plurality of feet are provided at the bottom of the base.

[0014] Compared with the prior art, the present application has at least the following beneficial effects:

[0015] 1. The film roll can be rotated above the acrylic material when film coating is required under the drive of the rotary cylinder and the drive of other structures. At this time, the film is pulled out manually for film coating work, which saves manpower, reduces the working intensity, is easier to align, reduces the position deviation, has a good film coating effect, and helps to improve the film coating efficiency. After the film coating is completed, the film roll rotates downward and automatically retracts to a suitable position, which does not affect the subsequent processes, and has simple operation, simplified structure, convenient processing and easy maintenance.

[0016] The cooperation of the guide rail and the slider can facilitate the film roll to be closer to the acrylic material and improve the alignment accuracy.

[0017] 2. The cooperation of the first fixing block and the second fixing block makes the replacement of the film roll more convenient.

[0018] 3. The outer shell helps to protect the film roll and prevent the film roll from being scratched. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following further details the present application through specific embodiments in conjunction with the accompanying drawings.

[0027] In the description of the present application: Unless otherwise specified, "a plurality of" means two or more. Terms such as "first", "second", "third", etc. in the present application are intended to distinguish the objects being referred to, and do not have special significance in terms of technical connotations (for example, it should not be understood as emphasizing the importance level or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0028] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in the present application are usually indications of the general relative position relationship for the convenience of intuitively understanding with reference to the accompanying drawings, and are not absolute limitations on the position relationship in the actual product.

[0029] A precise film placement positioning device, referring to Figures 1-4 , includes a vertical rod 1, and the vertical rod 1 maintains a vertical state. In the embodiment of the present application, the vertical rod 1 is made of aluminum profile. To improve the stability of the vertical rod 1, a horizontal base 16 is fixed at the bottom of the vertical rod 1. The base 16 adopts a square structure, and a plurality of support legs 17 are installed at the bottom of the base 16. In the present application, 4 support legs 17 are provided and are distributed at the four corner positions of the base 16.

[0030] A rotary cylinder 4 is installed at the top of the vertical rod 1. Specifically, the rotary cylinder 4 is fixed on the vertical rod 1 through a mounting seat 3. To improve the reliability of the rotary cylinder 4, an angle code 2 is connected between the mounting seat 3 and the side wall of the vertical rod 1 to achieve a strengthening effect.

[0031] The rotating shaft of the driving end of the rotary cylinder 4 is horizontal and perpendicular to the vertical rod 1, and a bracket 6 is installed at the driving end to drive the bracket 6 to rotate. The rotary cylinder 4 works to drive the bracket 6 to rotate in the vertical plane.

[0032] A guide rail 7 is installed on the bracket 6, and a slider 9 is matched on the guide rail 7. The sliding direction of the slider 9 is perpendicular to the vertical rod 1, so that the slider 9 can move away from or close to the laser cutting equipment during the sliding process.

[0033] Furthermore, an optical axis 11 for fixing the film roll is installed on the slider 9. Specifically, a connecting transition block 8 and a bearing seat 10 are also arranged between the slider 9 and the optical axis 11. The connecting transition block 8 is fixed on the side of the slider 9 away from the guide rail 7 to provide an installation position for other structures; the bearing seat 10 is fixed on the connecting transition block 8, and the optical axis 11 is installed on the bearing seat 10. Through the arrangement of the bearing seat 10, the optical axis 11 can also rotate freely to reduce the resistance of the film roll to rotate during the lamination process.

[0034] In order to limit the film roll and ensure the stability of the film roll position during the lamination process, a positioning member for preventing the film roll from falling is also provided on the optical axis 11. In this embodiment, the positioning member is selected from a first fixed block 12 and a second fixed block 14. The first fixed block 12 and the second fixed block 14 are the same components, both of which are fixed by two coaxial conical blocks, and the ends of the conical blocks with smaller radii are both facing one side of the film roll. In addition, the two conical blocks are of different sizes, the conical block away from the film roll is smaller, and the conical block close to the film roll is larger, and the maximum radius of the larger conical block is larger than the aperture in the center of the film roll, so that the hole in the center of the film roll can be stuck on the side of the conical block, and the conical block is used to limit the film roll.

[0035] The first fixing block 12 is fixed to one end of the optical axis 11 near the bearing seat 10, and is used to locate the installation position of the film roll. The second fixing block 14 is movably arranged on the optical axis 11 and can slide out from the other end of the optical axis 11. The second fixing block 14 is removed to facilitate the replacement of the film roll. After the replacement is completed, the second fixing block 14 is arranged on the optical axis 11 to press against the film roll to locate the film roll.

[0036] Regarding the fixing method of the second fixing block 14, bolt fixing can be used, or a thread of a certain length can be opened on the side wall at the corresponding position of the optical axis 11, and the second fixing block 14 can be threadedly matched with the optical axis 11. In the specific implementation process, the method can be selected according to the actual working conditions, as long as the second fixing block 14 can be freely taken out and fixed on the optical axis 11.

[0037] In order to protect the film roll and prevent it from being damaged, a housing 13 for sleeved outside the film roll is fixed on the optical axis 11. A bottom plate is provided at one end of the housing 13 close to the bearing seat 10, and a through hole corresponding to the first fixing block 12 is opened on the bottom plate so as not to affect the positioning of the film roll by the first fixing block 12. The other end of the housing 13 is not provided with a bottom plate so that the film roll can be replaced normally, and the second fixing block 14 can also enter and exit at this end.

[0038] Correspondingly, an opening 15 for the film to pass through is axially formed in the peripheral wall of the outer shell 13 to ensure the normal progress of film covering.

[0039] To reduce the resistance during film covering, the aperture at the center of the film roll is set to be slightly larger than the diameter of the optical axis 11, so that the film roll can rotate relative to the optical axis 11 after being sleeved on the optical axis 11.

[0040] To prevent the slider 9 from sliding out of the guide rail 7, at least one limit stop 5 is provided at the end of the guide rail 7. The limit stop 5 protrudes from the surface of the guide rail 7 to block the slider 9.

[0041] The implementation principle of the embodiment of the present application is as follows: The vertical rod 1 is arranged at one end of the laser cutting device. When film covering is not required, the rotating cylinder 4 drives the bracket 6 to rotate until the film roll is in a vertical state and is located at the end of the guide rail 7 away from the laser cutting device.

[0042] When film covering is required, the rotating cylinder 4 first drives the bracket 6 to rotate upward, driving the film covering to rotate to a horizontal state. Subsequently, manually drive the slider 9 to move the film covering on the guide rail 7 towards the side close to the laser cutting device to facilitate the alignment work. Finally, the worker pulls out the film from the opening 15 and covers the film on the acrylic, and the film covering operation can be completed.

[0043] After the film covering is completed, drive the film roll to return to its original position.

[0044] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered to be within the scope described in this specification.
