Description

Technical Field

[0001] This invention belongs to the field of animation production technology, and in particular relates to an animation copy table with magnetic fixing and rotation functions. Background Technology

[0002] An animation copy table (also known as a light tracer or tracing table) is one of the core tools in animation and comic production, mainly used for tracing, modifying, and layering animation frames. For example, an animation copy table disclosed in announcement number CN222548790U includes a housing with a frosted glass surface and a lightbox located below it within the housing. It also includes a first clamping mechanism and a second clamping mechanism. The second clamping mechanism includes a pressure roller and a sliding assembly. The pressure roller contacts the upper surface of the frosted glass surface. The housing has grooves on both sides for the sliding assembly to slide through. The sliding assembly includes a sliding post, a connecting post, and a spring. A movable cavity for the connecting post to slide in is formed at the top of the sliding post. A sliding shaft that mates with the groove is formed on the side wall of the sliding post. The spring is fixedly installed in the movable cavity, with its top end fixedly connected to the bottom of the connecting post and its bottom end fixedly connected to the bottom of the movable cavity. This solves the problem in existing copy tables where gaps exist between the original and blank paper, affecting the copying effect.

[0003] In 2D animation, keyframes are drawn by animators, while in-between frames are drawn by animators. A light table is often used for drawing because the drawing paper cannot remain stationary on the light table for long, and some lines require the light table to be rotated for smoother and more accurate lines. However, the animation light table described above cannot meet these requirements during the drawing process. Therefore, it is essential to design a system that can fix the paper and positioning ruler on the light table while allowing the light table to rotate. Summary of the Invention

[0004] This invention provides an animation copy table with magnetic fixing and rotation functions, aiming to solve the technical problem that the existing technology can only adjust the drawing position by moving the paper, and cannot adapt to drawing scenarios that require a rotating worktable, such as curved or tilted lines.

[0005] The present invention is implemented as follows: an animation copy table with magnetic fixing and rotation functions includes a copy table body, a first clamping component for fixing one side of the paper, and a second clamping component for fixing the other side of the paper, and also includes a rotating support. The bottom of the copy table body is fixed with a rotating ring that can rotate circumferentially on the rotating support, and the rotating support is provided with a magnetic positioning component for magnetically positioning the rotating ring.

[0006] The second clamping component is provided with sliding brackets on both sides, and the outer side of the copy table body is provided with a strip groove along the length direction of the copy table body, as well as a first limiting groove and a second limiting groove for sliding the sliding bracket along the direction of the strip groove.

[0007] The bottom of the strip groove near the first clamping component has a first toothed segment, and the bottom of the other side of the strip groove has a second toothed segment. The sliding bracket is provided with a transmission component. When the sliding bracket moves toward the first clamping component, it can be driven by the first toothed segment to rotate the second clamping component clockwise and lift the first clamping component upward. When the sliding bracket moves to the other side, it can be driven by the second toothed segment to rotate the second clamping component counterclockwise and press the paper.

[0008] Preferably, the rotating support includes a chassis, on which a magnetic ring and a fixed ring located inside the magnetic ring are fixed. The magnetic ring and the fixed ring are coaxially arranged and a gap is left between them for the insertion of a rotating ring. The rotating ring can rotate within the gap.

[0009] Preferably, the magnetic positioning component includes a magnetic slider, and the fixing ring has a plurality of telescopic grooves distributed at equal angles. The magnetic slider can slide radially within the telescopic grooves of the fixing ring and is elastically connected to the fixing ring by a spring.

[0010] Preferably, the outer end of the magnetic slider is spherical, the rotating ring has several circular holes, the circular part of the magnetic slider can extend outward through the circular holes, and the inner ring wall of the magnetic ring has a groove that matches the extended part of the magnetic slider.

[0011] Preferably, the first clamping component includes a first positioning pressure ruler. Both ends of the first positioning pressure ruler are rotatably connected to a bearing seat via a first rotating shaft. A first torsion spring is engaged at the connection between the first rotating shaft and the bearing seat. The elastic force of the first torsion spring causes the first positioning pressure ruler to rotate clockwise and press against the top surface of the copy table body. The bearing seat is fixed to the top surface of the copy table body. A U-shaped stop bar is fixed at the middle position of the first positioning pressure ruler.

[0012] Preferably, the second clamping component includes a second positioning pressure gauge, and a lever corresponding to the U-shaped stop bar is fixed at the middle position of the second positioning pressure gauge.

[0013] Preferably, the sliding bracket includes a side plate, and a bushing is fixed to one side of the top of the side plate. The second positioning pressure ruler is rotatably connected to the bushing via a second rotating shaft, and a second torsion spring is engaged at the connection between the second rotating shaft and the bushing. The elastic force of the second torsion spring causes the second positioning pressure ruler to approach contact with the top surface of the copy table body. A first limiting rod and a second limiting rod are rotatably connected to the side plate below the bushing. The first limiting rod and the second limiting rod are respectively limited within the first limiting groove and the second limiting groove.

[0014] Preferably, the transmission component includes a gear, which can mesh with a first tooth segment and a second tooth segment respectively when moving to both sides. The gear is coaxially fixed outside the first limiting rod, and a sector tooth is coaxially fixed on the outer end face of the gear. An annular tooth surface disposed on the circumferential surface of the bushing meshes above the sector tooth.

[0015] Compared with related technologies, the animation copy table with magnetic fixing and rotation functions provided by the present invention has the following beneficial effects:

[0016] 1. This invention achieves 360° rotation and precise positioning of the copy table body by adding a rotating support and magnetic positioning components, thus solving the problem of adapting the drawing angle. In contrast, the copy table body of the patent is a fixed structure, which can only adjust the drawing position by moving the paper, failing to adapt to the technical problem of drawing scenarios requiring a rotating worktable, such as curved or tilted lines.

[0017] 2. The present invention forms a linkage clamping mechanism by means of a first clamping component, a second clamping component and a transmission assembly, thereby realizing the automation and bidirectional adaptation of paper fixing. In contrast, the existing clamping mechanism, which combines a fixed first clamping mechanism and a sliding pressure roller, still requires manual lifting of the clamping bar to release the paper. The pressure roller can only smooth the paper in one direction, resulting in weak adaptability. Compared with the existing technology, the present invention designs a linkage structure of the first clamping component, the second clamping component and the transmission assembly to realize the automated operation of paper release, pressing, smoothing and bidirectional clamping.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] A preferred embodiment of the animation copy table with magnetic fixing and rotation functions provided by the present invention is as follows: Figures 1 to 10 As shown:

[0032] An animation copy table with magnetic fixing and rotation functions includes a copy table body 1, a first clamping component 5 for fixing one side of the paper, and a second clamping component 6 for fixing the other side of the paper. It also includes a rotating support 2. The bottom of the copy table body 1 is fixed with a rotating ring 3 that can rotate circumferentially on the rotating support 2. The rotating support 2 is provided with a magnetic positioning component 4 for magnetically positioning the rotating ring 3.

[0033] The second clamping component 6 is provided with sliding brackets 7 on both sides. The outer side of the copy table body 1 is provided with a strip groove 11 along the length direction of the copy table body 1, as well as a first limiting groove 12 and a second limiting groove 13 that limit the sliding bracket 7 to slide along the strip groove 11.

[0034] The bottom of the strip groove 11 near the first clamping component 5 is provided with a first tooth segment 9, and the bottom of the other side of the strip groove 11 is provided with a second tooth segment 10. The sliding bracket 7 is provided with a transmission component 8. When the sliding bracket 7 moves toward the first clamping component 5, it can be driven by the first tooth segment 9 to rotate the second clamping component 6 clockwise and lift the first clamping component 5 upward. When the sliding bracket 7 moves to the other side, it can be driven by the second tooth segment 10 to rotate the second clamping component 6 counterclockwise and press the paper.

[0035] Furthermore, the rotating support 2 includes a base 21. The base 21 of the rotating support 2 can be fitted with an anti-slip pad similar to the anti-slip rubber pad in the comparative patent, or it can be fixed with a suction cup to cooperate with the rotation positioning system to ensure overall stability during rotation adjustment. A magnetic ring 22 and a fixing ring 23 located inside the magnetic ring 22 are fixed on the base 21. The magnetic ring 22 and the fixing ring 23 are coaxially arranged and a gap is left between them for the insertion of the rotating ring 3. The rotating ring 3 can rotate within the gap. The rotating support 2 is composed of a base 21, a magnetic ring 22, and a fixing ring 23, which are coaxially arranged. The rotation gap between the magnetic ring 22 and the fixing ring 23 provides a support frame for the rotating ring 3.

[0036] Furthermore, the magnetic positioning component 4 includes a magnetic slider 41. The fixed ring 23 has several equally angled telescopic grooves 231. The magnetic slider 41 can slide radially within the telescopic grooves 231 of the fixed ring 23 and is elastically connected to the fixed ring 23 via a spring 42. The magnetic ring 22 magnetically attracts the magnetic slider 41, achieving the positioning function. The rotating ring 3 is fixed to the bottom of the copy table body 1 and embedded in the gap of the rotating support. The outer end of the magnetic slider 41 is spherical. The rotating ring 3 has several circular holes 31, allowing the spherical part of the magnetic slider 41 to extend outwards through the circular holes 31. The inner ring wall of the magnetic ring 22 extends outward and has a groove 221 that matches the extended part of the magnetic slider 41. When rotating, the rotating ring 3 squeezes the round head of the slider, and the slider compresses the spring 42 and retracts into the telescopic groove 231, releasing the positioning. When positioning, the slider, under the action of the elastic force of the spring 42 and the magnetic force of the magnetic ring 22, is inserted into the groove 221 of the magnetic ring 22 through the round hole 31 to achieve angle locking. This system can meet the angle adjustment needs of animators when drawing smooth curves, and the magnetic positioning method has no mechanical jamming. The positioning accuracy is guaranteed by the equal angular distribution of the round holes 31, such as setting a positioning point every 15° / 30°.

[0037] Furthermore, the first clamping component 5 includes a first positioning pressure ruler 51. Both ends of the first positioning pressure ruler 51 are rotatably connected to a bearing seat 53 via a first rotating shaft 52. A first torsion spring 54 is engaged at the connection between the first rotating shaft 52 and the bearing seat 53. The elastic force of the first torsion spring 54 causes the first positioning pressure ruler 51 to rotate clockwise and press against the top surface of the copy table body 1. The bearing seat 53 is fixed to the top surface of the copy table body 1. A U-shaped stop bar 55 is fixed at the middle position of the first positioning pressure ruler 51. The first clamping component 5 consists of the first positioning pressure ruler 51, the first torsion spring 54, and the U-shaped stop bar 55. The elastic force of the first torsion spring 54 causes the pressure ruler to be normally closed and press the paper tightly.

[0038] Furthermore, the second clamping component 6 includes a second positioning pressure plate 61. A lever 64, corresponding to the U-shaped stop bar 55, is fixed at the middle position of the second positioning pressure plate 61. The second clamping component 6 consists of the second positioning pressure plate 61, a second torsion spring 63, and a lever 64. The lever 64 precisely corresponds to the U-shaped stop bar 55 of the first clamping component 5. When the second clamping component 6 moves toward the first clamping component 5, the lever 64 can move the U-shaped stop bar 55, thereby automatically lifting the first positioning pressure plate 51. When the second clamping component 6 moves away from the first clamping component 5, the first positioning pressure plate 51 automatically resets without manual operation.

[0039] Furthermore, the sliding bracket 7 includes a side plate 71, with a bushing 72 fixed to one side of the top of the side plate 71. A second positioning pressure gauge 61 is rotatably connected to the bushing 72 via a second rotating shaft 62, and a second torsion spring 63 is engaged at the connection between the second rotating shaft 62 and the bushing 72. The elastic force of the second torsion spring 63 causes the second positioning pressure gauge 61 to approach contact with the top surface of the copy table body 1. A first limiting rod 73 and a second limiting rod 74 are rotatably connected to the side plate 71 below the bushing 72. The first limiting rod 73 and the second limiting rod 74 are respectively limited within the first limiting groove 12 and the second limiting groove 13. The first limiting rod 73 and the second limiting rod 74 of the sliding bracket 7 are respectively embedded in the first limiting groove 12 and the second limiting groove 13 of the copy table body 1 to ensure no offset during movement and to avoid misalignment.

[0040] Furthermore, the transmission component 8 includes a gear 81, which can mesh with the first tooth segment 9 and the second tooth segment 10 respectively when moving to both sides. The gear 81 is coaxially fixed outside the first limiting rod 73. The outer end face of the gear 81 is coaxially fixed with a sector tooth 82, and the upper part of the sector tooth 82 is meshed with an annular tooth surface 83 provided on the circumferential surface of the bushing 72.

[0041] The paper feeding stage is as follows: the sliding bracket 7 moves toward the first clamping component 5 → the gear 81 meshes with the first tooth segment 9 → the first limiting rod 73 drives the sector tooth 82 to rotate counterclockwise → the sector tooth 82 drives the annular tooth surface 83 of the bushing 72 → the second positioning pressure gauge 61 rotates clockwise → the lever 64 lifts the U-shaped stop bar 55, and the first positioning pressure gauge 51 lifts synchronously to form a paper feeding gap.

[0042] The clamping stage is as follows: the sliding bracket 7 moves in the opposite direction → the gear 81 meshes with the first tooth segment 9, the first positioning pressure ruler 51 and the second positioning pressure ruler 61 are reset → the gear 81 meshes with the second tooth segment 10 → the sector tooth 82 rotates clockwise → the second positioning pressure ruler 61 rotates counterclockwise → the paper is clamped at both ends simultaneously, and the second positioning pressure ruler 61 smooths out the paper wrinkles during the movement.

[0043] In use, the second clamping component 6 is moved to a side close to the first clamping component 5 via the sliding brackets 7 at both ends. During this process, when the gear 81 is about to mesh with the first tooth segment 9, the lever 64 at the middle position of the second positioning pressure ruler 61 extends just below the U-shaped stop bar 55. Then, under the meshing of the gear 81 and the first tooth segment 9, the first limiting rod 73 drives the sector tooth 82 to rotate counterclockwise. Under the meshing of the sector tooth 82 and the annular tooth surface 83, the bushing 72 rotates clockwise. Thus, the lever 64 can move the U-shaped stop bar 55 to make the first positioning pressure ruler 51 overcome the elastic force of the first torsion spring 54 and lift the first positioning pressure ruler 51 upward synchronously with the second positioning pressure ruler 61. Thus, one end of the manuscript paper and the blank paper can be extended from below the second positioning pressure ruler 61 to below the first positioning pressure ruler 51.

[0044] Then the second clamping component 6 is moved to the other side via the sliding brackets 7 at both ends. During this process, the first positioning pressure ruler 51 is reset by the transmission component 8 and the first tooth segment 9, pressing one end of the manuscript paper and the blank paper together. The second positioning pressure ruler 61 moves to the opposite side to lay the manuscript paper and the blank paper flat on the top surface of the copy table body 1. When the gear 81 meshes with the second tooth segment 10, the first limiting rod 73 drives the sector tooth 82 to rotate clockwise. Under the meshing of the sector tooth 82 and the annular tooth surface 83, the bushing 72 rotates counterclockwise, thereby pressing the other end of the manuscript paper and the blank paper together by the lever 64, preventing the upper and lower papers and the positioning ruler from shifting.

[0045] During the drawing process, the copy table body 1 on the rotating support 2 can be rotated relative to each other. The magnetic slider 41 is squeezed by the rotating ring 3, causing it to overcome the elastic force of the spring 42 and the magnetic attraction force of the magnetic ring 22 and retract into the telescopic groove 231. This allows the rotating support 2 to be rotated by a certain angle. When the rotating support 2 is released, the magnetic slider 41 automatically extends out of the telescopic groove 231 under the action of the elastic force of the spring 42 and the magnetic attraction force of the magnetic ring 22. The round end of the magnetic slider 41 can be attracted to the groove 221 of the magnetic ring 22 through the adjacent round hole 31, thereby achieving automatic positioning of the rotating support 2 after rotation.
