A rotating pattern disc for precisely positioning the pattern location

Abstract

A rotating pattern disc for precisely positioning the position of a pattern. The position and orientation of the pattern installation are precisely positioned through the first positioning mark on the pattern piece, the second positioning mark on the pattern self-rotating gear disc, and the third positioning mark on the central gear disc. At the same time, the tooth number ratio of the central gear disc and the pattern self-rotating gear disc is limited to avoid the cumulative error caused by the long-term rotation of the pattern self-rotating gear disc, so that after the long-term operation of the pattern rotating disc, the effect of multiple lamps projecting the same pattern piece is still precisely consistent.

Description

Technical Field

[0001] The present invention belongs to the field of stage lights, and particularly relates to a rotating pattern disc for precisely positioning the positions of patterns. Background Art

[0002] For the existing rotating pattern discs used in stage lights, in order to pursue rich lighting colors and stage effects, a plurality of pattern inserts are required. The pattern inserts are used to fix the pattern pieces, and various pattern pieces are snapped into the pattern inserts. By rotating the rotating pattern disc, various pattern pieces can be switched, so as to project different patterns to meet the stage effects.

[0003] Among them, the rotating pattern disc for stage lights further includes a central gear disc. Each pattern insert is provided with a pattern gear disc. Each pattern gear disc is arranged around the central gear disc and meshes with the central gear disc for transmission. Thus, the central gear disc drives the pattern gear disc to realize the self-rotation of the pattern pieces in the pattern insert. Moreover, the self-rotation of the central gear disc can drive each pattern gear disc to revolve around the central gear disc.

[0004] It should be particularly noted that the rotating pattern discs for stage lights are generally mass-produced, that is, the rotating pattern discs of these stage lights produced in batches correspond to the same set of pattern pieces. However, the patterns of the individual pattern pieces in a set of pattern pieces are generally different. During mass production, although the arrangement order of the pattern pieces of the rotating pattern discs for stage lights of the same specification around the central gear disc can be controlled.

[0005] In the prior art, the general order of installing the pattern pieces onto the rotating pattern disc for stage lights is as follows: First, install each pattern piece onto the pattern self-rotation gear disc, and then snap the pattern self-rotation insert onto the central gear disc of the revolving turntable according to the arrangement order of the pattern pieces. When installing the pattern pieces of the next rotating pattern disc for stage lights, it is roughly judged by the human eye to roughly ensure that the orientation (orientation means the direction of facing) of each pattern piece is consistent with the orientation of the corresponding pattern piece in the previous rotating pattern disc for stage lights. After accumulating and installing the pattern pieces of multiple rotating pattern discs for stage lights, it is easy to occur that the orientations (orientations mean the directions of facing) of the same pattern piece at the same position of each rotating pattern disc for stage lights are inconsistent. For example, in the patent application documents with the patent application numbers CN201810188197.4 and CN201820220480.6, similar problems still occur in their rotating pattern discs, which urgently need to be improved.

[0006] In addition, with the development of society, the content of the patterns on stage lights is no longer limited to relatively symmetrical images in the past, but characters, flowers and plants, human figures, animals, etc. have begun to appear. In this case, when multiple stage lights of the same specification perform together, the precision requirements for the direction and angle consistency of the images on the pattern pieces are much higher than the past traditional standards, and the simple pattern piece positioning structure can no longer meet the requirements. As can be seen from the patent application document with the patent number CN209325641U through its patent literature and drawings, "Preferably, a magnet is installed in the first positioning hole 32 of the pattern gear disk 31 on one side of the white light hole 11, that is, a magnet is installed in the first positioning hole 32 of the pattern gear disk 31 closest to the white light hole 11 on one side of the white light hole 11. The Hall sensor installed on the stage light itself can identify the magnet, so as to initially determine the position of the pattern piece installed on the turntable 1, so as to facilitate accurately determining the position of each pattern piece during work." It only solves the installation and positioning problem of the pattern gear disk where the magnet is located, and does not solve the installation and positioning of the pattern pieces on the other pattern gear disks, nor can it achieve precise positioning of each pattern piece.

[0007] At the same time, because its "first positioning holes (32) are respectively located on the end faces of the respective pattern gear disks", and those skilled in the art know that when the pattern piece is installed on the pattern self-rotating gear disk, it is actually installed from the reverse side of the end face of the pattern self-rotating gear disk. At this time, the "first positioning holes (32)" cannot be seen, that is, when installing, it is still necessary to rely on the naked eye and feeling to correct the position of the pattern piece with the "first positioning holes (32)". Therefore, the main function of the "first positioning holes (32)" is actually to correspond to the "second positioning holes (21)", that is, it still cannot achieve very precise installation and positioning of the pattern piece on the pattern gear disk where the magnet is located.

[0008] Therefore, how to design a rotating pattern disk that can accurately position the pattern so that the pattern pieces can be accurately and uniformly installed, so that when multiple stage lights of the same model project the same pattern piece on the rotating pattern disk, the angles and orientations of the patterns can be almost exactly the same is the problem to be solved by this patent. Summary of the Invention

[0009] The purpose of the present invention is to provide a rotating pattern disk that can accurately position the pattern, and the purpose of the present invention is achieved through the following technical solutions:

[0010] A rotating pattern disc for precisely positioning the position of a pattern, comprising a revolving turntable, a central gear disc installed at the center of the revolving turntable, and a number of pattern self-rotating inserts installed on the revolving turntable. Each of the pattern self-rotating inserts is provided with a pattern self-rotating gear disc. Each of the pattern self-rotating gear discs is arranged around the central gear disc and meshes with the central gear disc. Each of the pattern self-rotating gear discs is provided with a pattern installation hole for accommodating a pattern piece. It is characterized in that each of the pattern pieces is provided with a first positioning mark, each of the pattern self-rotating gear discs is provided with a second positioning mark, and the central gear disc is provided with a third positioning mark having the same number as the number of pattern self-rotating inserts.

[0011] Further, the number of teeth of the central gear disc is divisible by the number of teeth of the pattern self-rotating gear disc.

[0012] Further, the tooth number ratio of the central gear disc to the pattern self-rotating gear disc is 2:1.

[0013] Further, the first positioning mark is located at the edge of the pattern piece.

[0014] Further, an annular silk-screening circle is provided at the edge of the pattern piece, and the first positioning mark is a circular small hole pattern located within the annular silk-screening circle.

[0015] Further, the second positioning mark is close to the outer periphery of the pattern self-rotating gear disc.

[0016] Further, the second positioning mark includes a positioning hole on the end face of the pattern self-rotating gear disc and a positioning groove on the back face of the pattern self-rotating gear disc.

[0017] Further, the axes of the positioning hole and the positioning groove are collinear at two points along the radial direction of the pattern self-rotating gear disc.

[0020] Compared with the prior art, the present technical solution has the following obvious advantages:

DETAILED DESCRIPTION OF THE INVENTION

[0028] The innovative points of the present invention will be further described below with reference to the accompanying drawings.

[0029] As shown in the Figures 1-3 accompanying drawings, a rotating pattern disk for accurately positioning the pattern includes a revolving turntable (1), a central gear disk (2) installed at the center of the revolving turntable (1), and a plurality of pattern self-rotating plugins (3) installed on the revolving turntable (1). Each of the plurality of pattern self-rotating plugins (3) is provided with a pattern self-rotating gear disk (31). Each pattern self-rotating gear disk (31) is arranged around the central gear disk (2), and each pattern self-rotating gear disk (31) meshes with the central gear disk (2). Each pattern self-rotating gear disk (31) is provided with a pattern installation hole (313) for accommodating the pattern piece (4); each pattern piece (4) is provided with a first positioning mark (41), each pattern self-rotating gear disk (31) is provided with a second positioning mark, and the central gear disk (2) is provided with third positioning marks (21) having the same number as the plurality of pattern self-rotating plugins (3).

[0030] As a preferred embodiment, the number of teeth of the central gear disk (2) is divisible by the number of teeth of the pattern self-rotating gear disk (31). At this tooth ratio, when the central gear disk (2) rotates one circle, the pattern self-rotating gear disk (31) rotates an integer number of circles. The advantage of this is that it avoids the mechanical error problem of tooth number remainder caused by the central gear disk (2) rotating one circle while the pattern self-rotating gear disk (31) rotates a non-integer number of circles, such as 1 / 3 circle. As a person skilled in the art, it can be understood that if there is a problem of tooth number remainder error, it will generate a cumulative error after the central gear disk (2) rotates multiple circles, which will lead to the failure of the positioning marks of each pattern self-rotating gear disk (31) and the central gear disk (2), resulting in deviations or even differences in the specific projection directions of the same pattern projected by multiple lamps in the same batch.

[0031] Specifically, in this embodiment, the tooth ratio of the central gear disk (2) to the pattern self-rotating gear disk (31) is 2:1, that is, when the central gear disk rotates one circle, the self-rotating gear disk rotates two circles. This tooth ratio is more suitable for the actual use of the pattern disk.

[0032] As a preferred embodiment, the first positioning mark (41) is located at the edge of the pattern piece (4).

[0033] Specifically, an annular silk-screening circle (42) is provided at the edge of the pattern piece (4), and the first positioning mark (41) is a circular small hole pattern (41) located within the annular silk-screening circle (42).

[0034] As a preferred embodiment, the second positioning mark is close to the outer circumference of the pattern self-rotating gear disk (31), which is convenient for the second positioning mark to be respectively positioned with the first positioning mark (41) and the third positioning mark (21).

[0035] Specifically, the second positioning mark includes a positioning hole (311) located on the end face of the pattern self-rotating gear disk (31) and a positioning groove (312) located on the back of the pattern self-rotating gear disk (31); when the pattern self-rotating plug hole (311) is installed on the revolving turntable (1), and in the meshing state of each pattern self-rotating gear disk (31) and the central gear disk (2), the positioning holes (311) on each pattern self-rotating gear disk (31) are aligned with the respective third positioning marks (21) on the central gear disk (2). At this time, the installation direction of each pattern self-rotating gear disk (31) is precise and unique; when the pattern piece (4) is installed into the pattern installation hole (313) on the pattern self-rotating gear disk (31), the first positioning mark (41) on the pattern piece (4) is aligned with the positioning groove (312) on the pattern self-rotating gear disk (31). At this time, the installation direction of each pattern piece (4) is also precise and unique.

[0036] Further, the axes of the positioning holes (311) and the positioning grooves (312) are collinear at two points along the radial direction of the pattern rotating gear disc (31). The first positioning mark (41) is aligned with the positioning groove (312), and the third positioning mark (21) is aligned with the positioning hole (311). Therefore, the axes of the first positioning mark (41), the positioning groove (312), the positioning hole (311), and the third positioning mark (21) are collinear at four points along the radial direction of the pattern rotating gear disc (31).

[0037] As a preferred embodiment, the third positioning mark (21) is a silk-screen line (21). One end of the silk-screen line (21) points to the center of the center gear disc (2), and the other end points to the outer circumference of the center gear disc (2).

[0038] Specifically, several silk-screen lines (21) evenly divide the center gear disc (2) at equal angles. Each silk-screen line (21) corresponds to one pattern rotating gear disc (31). More specifically, one silk-screen line (21) corresponds to the positioning hole (311) on one pattern rotating gear disc (31).

[0039] During the actual assembly of the rotating pattern disc, as those skilled in the art can understand, the forms of the first positioning mark, the second positioning mark, and the third positioning mark can be changed, but their functions are all to accurately position the assembly position and direction.

[0040] Optionally, the third positioning mark (21) is a silk-screen line (21). Several silk-screen lines (21) can be directly silk-screened on the surface of the center gear disc (2), or as shown in the appendix Figure 2 Several silk-screen lines (21) are silk-screened on a silk-screen sticker (24), and then the silk-screen sticker (24) is pasted on the surface of the center gear disc (2). At this time, there is a reference hole a (22) on the silk-screen sticker (24), and a reference hole A (23) on the center gear disc (2). By the coincidence of the reference hole a (22) and the reference hole A (23), the same pasting position and direction of the silk-screen stickers (24) of different lamps can be ensured.

[0041] Optionally, the pattern piece (4) can be a glass pattern piece or a metal pattern piece, as long as it has a circular pattern small hole as the first positioning mark (41). Its function is to ensure that the installation direction of the pattern piece is unique. As shown in the appendix Figure 3 The state diagram of the pattern rotating gear disc (31) with the pattern piece installed, and the pattern piece is a transparent glass pattern piece.

[0042] In the actual manufacturing process, when assembling the rotating pattern disc, it includes two steps. One is to install the pattern piece (4) into the pattern mounting hole (313) on the pattern self-rotating gear disc (31), and the other is to install the pattern self-rotating plug-in (3) onto the revolving turntable (1) and engage it with the central gear disc (2). To ensure that the positions and directions of the pattern pieces are exactly the same when a batch of the same type of lamps are performing, it is necessary to ensure that the positions and directions of the pattern pieces (4) on each pattern self-rotating gear disc (31) are exactly the same, that is, precise positioning for installing the pattern piece (4) and the pattern self-rotating gear disc (31) is required.

[0043] In the present invention, as shown in the appendix Figure 3 Each pattern self-rotating gear disc (31) includes a positioning hole (311) located on the end face and a positioning groove (312) located on the back face. In the lighting industry, the pattern piece (4) is generally installed from the back face of the pattern self-rotating gear disc (31). When installing, align the first positioning mark (41) on the pattern piece (4) with the positioning groove (312), and the pattern piece (4) can be precisely positioned for installation. The installation of several pattern pieces (4) on one revolving turntable (1) onto the corresponding pattern self-rotating gear discs (31) all adopts the same method, thus ensuring the precise relative position between each pattern piece (4) and the pattern self-rotating gear disc (31).

[0044] When installing the pattern self-rotating plug-in (3) onto the revolving turntable (1), the end face of the pattern self-rotating gear disc (31) in the pattern self-rotating plug-in (3) has a positioning hole (311). When installing, align the positioning hole (311) with the third positioning mark (21) of the central gear disc, and the position of the pattern self-rotating gear disc (31) can be precisely positioned, thereby precisely positioning the position of the pattern self-rotating plug-in (3). The installation of several pattern self-rotating plug-ins (3) on one revolving turntable (1) is aligned one by one with the corresponding several third positioning marks (21), thus ensuring the precise relative position between each pattern self-rotating plug-in (3) and the central gear disc (2), and thereby ensuring the precise relative position between each pattern self-rotating gear disc (31) and the central gear disc (2).

[0045] At the same time, because the axes of the positioning hole (311) and the positioning groove (312) are collinear at two points along the radial direction of the pattern self-rotating gear disc (31), therefore, actually after installation, the axes of the first positioning mark (41), the positioning groove (312), the positioning hole (311), and the third positioning mark (21) involved in the final positioning of each pattern are collinear at four points along the radial direction of the pattern self-rotating gear disc (31). Finally, as long as the arrangement order of several pattern pieces in a rotating pattern disc along the circumference is specified, it can be achieved that the position of each specific pattern piece is precisely positioned relative to the entire rotating pattern disc.

[0046] The above embodiments are only further descriptions of the technical solutions of the present invention, rather than limiting the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
