Description

Technical Field

[0001] The present invention relates to the technical field of detection light sources, and particularly to a combined programmable light source with adjustable color temperature. Background Art

[0002] Traditional light sources with high color temperature requirements can only customize light sources with high-precision color temperature requirements by subdividing and controlling the color temperature of lamp beads. For different color temperature requirements, only lamp bead replacement can be used. The same light source cannot be adjusted for color temperature arbitrarily. Moreover, the cost of lamp beads with subdivided color temperature is extremely high, and the customized color temperature is extremely single. Therefore, the cost of traditional light source lamp beads with color temperature requirements is extremely high, and when adjusting the color temperature of the finished light source, it is greatly affected by the external factors such as the surface treatment of parts. The human and material resources for debugging the finished lamp beads are huge, and the waste of lamp beads is also extremely serious. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a combined programmable light source with adjustable color temperature. The present invention can arbitrarily adjust the desired color temperature, and the application scenarios are more flexible and extensive. Moreover, when designing this light source, a reserved external light source port is added, and various light sources can be combined at will.

[0004] To achieve the above purpose, the present invention provides a device for automatically polishing special-shaped plates, including:

[0005] A bottom plate and a housing connected to the bottom plate. An light outlet is provided on the bottom plate, and a detection inlet is provided on the housing;

[0006] On the bottom plate, a first annular light source, a shadowless light source, a second annular light source, and a coaxial light source that are coaxially arranged with the light outlet and the detection inlet are detachably connected in sequence from bottom to top. The first annular light source, the shadowless light source, the second annular light source, and the coaxial light source all adopt two-color temperature controllable lamp beads;

[0007] A first control circuit board and a second control circuit board electrically connected to the first control circuit board are further provided inside the housing. The second control circuit board is used to control the on and off of different color temperatures of the two-color temperature controllable lamp beads of the first annular light source, the shadowless light source, the second annular light source, and the coaxial light source.

[0008] Further, the two-color temperature controllable lamp bead includes a lamp bead body, a first lamp bead and a second lamp bead arranged on the lamp bead body, and a first chip and a second chip for controlling the first lamp bead and the second lamp bead. A first pin and a second pin that are electrically connected to the first lamp bead and the second lamp bead are arranged on the lamp bead body, and there are two groups of first pins and second pins respectively. The two-color temperature controllable lamp bead with two chips and four pins of high and low two-color temperatures is adopted. The two-color temperature controllable lamp bead is composed of a high and a low white lamp beads. In the finished combined light source, the second control circuit board is used to separately control the current of the two light-emitting chips of the lamp bead to adjust the light-emitting brightness of the two chips of the lamp bead, so as to achieve the adjustment of the color temperature.

[0009] Further, the first control circuit board is connected to an external panel. A number of reserved external power plugs electrically connected to the first control circuit board are arranged on the external panel. The external panel is fixedly connected to the end of the housing, and a first opening matching the detection inlet is arranged on the external panel. A number of first connection holes are arranged on the external panel. Through the reserved external power plugs, more different light source modules can be connected as needed to meet the requirements of various functions, thereby improving the expandability of the present invention.

[0010] Further, second connection holes are arranged on the side edge of the external panel, and third connection holes matching the second connection holes are arranged on the top side wing of the housing. Through the cooperation of the second connection holes and the third connection holes with connectors such as screws, the detachable connection between the external panel and the housing can be realized, improving the installation and disassembly and repair efficiency.

[0011] Further, a second opening and a third opening are respectively arranged in the middle of the first control circuit board and the second control circuit board. The first control circuit board and the second control circuit board are hung on the outside of the coaxial light source through the second opening and the third opening. The shapes and diameters of the second opening and the third opening match the shape and outer diameter of the coaxial light source, so that the first control circuit board and the second control circuit board can be directly passed through the outer surface of the coaxial light source, and bonding or detachable fixation can be realized through glue or other connectors. This setting can effectively improve the space utilization rate and reduce the production cost.

[0012] Further, the first annular light source is a low-angle annular light source, and the second annular light source is a high-angle annular light source. The low-angle annular light source (usually <45°) projects the surface texture and edge contour of the object through lateral illumination, while the high-angle annular light (usually ≥45°) is close to vertical illumination and is more suitable for planar detection and reducing texture interference.

[0013] Further, the shadowless light source is a ring-shaped shadowless light source. A connecting ring body is arranged on the lower side of the shadowless light source, and a fourth connecting hole is arranged on the connecting ring body. A fifth connecting hole matching the fourth connecting hole is arranged at the upper end of the first ring-shaped light source. An L-shaped first connecting piece is connected to the upper end of the shadowless light source, and the other end of the first connecting piece is connected to the second ring-shaped light source. The first ring-shaped light source and the shadowless light source are connected through the fourth connecting hole and the fifth connecting hole by means of connecting pieces such as screws. Moreover, the first connecting piece enables the rapid connection between the shadowless light source and the second ring-shaped light source, thereby realizing a smooth transition from a small diameter to a large diameter, making the overall arrangement more reasonable, enabling each group of light sources not to interfere with each other, and realizing combined and independent operations.

[0014] Further, the coaxial light source is arranged at the upper end of the second ring-shaped light source, and is connected between the coaxial light source and the second ring-shaped light source through a second connecting piece provided. The second connecting piece can realize the rapid installation and disassembly of the coaxial light source and the second ring-shaped light source, improving efficiency.

[0015] Further, heat dissipation through holes and a heat dissipation fan are arranged on the side edge of the housing. Heat can be effectively dissipated through the heat dissipation through holes and the heat dissipation fan, ensuring the stable operation of each light source inside.

[0016] Further, a dust-proof glass is arranged at the light outlet. This prevents dust from entering the interior of the housing and interfering with the operation of the internal light sources, effectively improving the working stability of each component.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention adopts a two-color temperature controllable lamp bead with high and low two-color temperatures, two chips, and four pins. The two-color temperature controllable lamp bead is composed of a high and a low white lamp bead. In the finished combined light source, an internal control board is used to separately control the current of the two light-emitting chips of the lamp bead to adjust the light-emitting brightness of the two chips of the lamp bead, thereby achieving the adjustment of the color temperature. Thus, each individual light source in the combined light source of the present invention can arbitrarily adjust the desired color temperature, and the application scenarios are more flexible and extensive. Moreover, a reserved external light source port is added, and various light sources can be arbitrarily combined.

[0019] The present invention combines different-sized and different-angled ring lights, shadowless lights, coaxial lights, etc. in the combined light source to achieve the integration of different color temperature light sources required for different parts of the same product onto a single combined light source, completing the detection in one step, avoiding the waste of cost and time in the detection of multiple light sources and multiple processes, and greatly reducing the waste of cost and time in this high-precision multi-station color temperature detection scenario.

[0028] Next, the technology 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 one embodiment of the present invention, rather than all embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as described in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0031] Please refer to Figures 1 to 5 , the embodiments of the present invention provide an adjustable color temperature combined programmable light source, including:

[0032] A bottom plate 1 and a housing 2 connected to the bottom plate 1. An light outlet 11 is provided on the bottom plate 1, and a dust-proof glass 12 is provided on the light outlet 11, thereby preventing dust from entering the interior of the housing 2 and interfering with the operation of the internal light source, effectively improving the working stability of each component; A detection inlet 21 is provided at the upper end of the housing 2. As Figure 1 shown, the housing 2 of this embodiment is a tubular structure with openings at both the upper and lower ends. A fifth connection hole 13 is provided on the bottom plate 1, and a sixth connection hole 22 matching the fifth connection hole 13 is provided at the lower end of the housing 2. During assembly, the fifth connection hole 13 and the sixth connection hole 22 are aligned and then locked through connecting pieces such as screws to achieve detachable connection between the two. To increase the heat dissipation effect inside the housing 2, heat dissipation through holes 23 and a heat dissipation fan 24 are also provided on the housing 2. As shown in the figure, two groups of heat dissipation through holes 23 and two heat dissipation fans 24 are provided on the housing 2. The two groups of heat dissipation through holes 23 and the two heat dissipation fans 24 are evenly distributed on the housing 2 respectively to improve the overall heat dissipation uniformity, and the effect is better;

[0033] On the bottom plate 1, a first annular light source 3, a shadowless light source 4, a second annular light source 5, and a coaxial light source 6, which are coaxially arranged with the light outlet 11 and the detection inlet 21, are detachably connected in sequence from bottom to top. Among them, the first annular light source 3 is a low-angle annular light source, and the second annular light source 5 is a high-angle annular light source. The low-angle annular light source (usually the angle between the lamp beads and the horizontal plane is less than 45°) laterally irradiates to highlight the surface texture and edge contour of the object, while the high-angle annular light (the angle between the lamp beads and the horizontal plane ≥ 45°) irradiates nearly vertically, which is more suitable for planar detection and reducing texture interference.

[0034] The connection relationship of each of the above light sources is that a seventh connection hole 14 is provided on the bottom plate 1, and an eighth connection hole 31 matching the seventh connection hole 14 is provided at the bottom of the first annular light source 3. During assembly, the seventh connection hole 14 and the eighth connection hole 31 are connected by a connecting piece such as a screw to realize the detachable connection between the first annular light source 3 and the bottom plate 1. The shadowless light source 4 is an annular shadowless light source 4. A connecting ring body 41 is provided on the lower side of the shadowless light source 4, and a fourth connection hole 42 is provided on the connecting ring body 41. A fifth connection hole 13 matching the fourth connection hole 42 is provided at the upper end of the first annular light source 3. During assembly, the fourth connection hole 42 and the fifth connection hole 13 are aligned and locked by a connection such as a screw, thereby realizing the detachable setting of the shadowless light source 4 above the first annular light source 3.

[0035] An L-shaped first connecting piece 43 is connected to the upper end of the shadowless light source 4, and the other end of the first connecting piece 43 is connected to the second annular light source 5. Specifically, in this embodiment, a total of four first connecting pieces 43 are provided. The four first connecting pieces 43 are evenly distributed on the upper end of the shadowless light source 4 and are locked to the upper end of the shadowless light source 4 by a connecting piece such as a screw. The other ends of the first connecting pieces 43 are uniformly locked to the side edge of the second annular light source 5 by a connecting piece such as a screw. The coaxial light source 6 is arranged at the upper end of the second annular light source 5, and a second connecting piece 51 is provided between the coaxial light source 6 and the second annular light source 5. Since the coaxial light source 6 is square, when the coaxial light source 6 is installed at the upper end of the second annular light source 5, there is a space on the upper end of the second annular light source 5 that is not covered by the coaxial light source 6. The second connecting piece 51 has the same structure as the first connecting piece 43, and is integrally in an "L" shape. During assembly, one end of the second connecting piece 51 is locked to the upper end of the second annular light source 5 by a connecting piece such as a screw, and the other end is locked to the side wall of the coaxial light source 6.

[0036] Through the above connections, the first annular light source 3, the shadowless light source 4, the second annular light source 5, and the coaxial light source 6 are stacked and arranged from bottom to top, as Figure 2As shown in the figure, to ensure that each light source can operate normally and accurately without interfering with each other, the first annular light source 3 is provided with a first annular light outlet 32 and a first annular light inlet 33, the shadowless light source 4 is provided with a shadowless light outlet 44 and a shadowless light inlet 45, the second annular light source 5 is provided with a second annular light inlet 52 and a second annular light outlet 53, and the coaxial light source 6 is provided with a coaxial light outlet 61 and a coaxial light inlet 62. The first annular light outlet 32 of the first annular light source 3 is adjacent to the light outlet 11 of the bottom plate 1, and the diameter of the first annular light outlet 32 can be less than or equal to the diameter of the light outlet 11, so as to ensure the stability of the overall light output. The diameter of the first annular light inlet 33 is less than the diameter of the first annular light outlet 32, and the diameter of the first annular light inlet 33 is greater than the diameter of the shadowless light outlet 44. The diameters of the shadowless light outlet 44, the shadowless light inlet 45, and the second annular light outlet 53 are the same, and the diameters of the second annular light inlet 52, the coaxial light outlet 61, the coaxial light inlet 62, and the detection inlet 21 are consistent.

[0037] In this embodiment, the first annular light source 3, the shadowless light source 4, the second annular light source 5, and the coaxial light source 6 all adopt two-color temperature controllable lamp beads 9. A first control circuit board 7 and a second control circuit board 8 electrically connected to the first control circuit board 7 are further provided inside the housing 2. The second control circuit board 8 is used to control the on and off of different color temperatures of the two-color temperature controllable lamp beads 9 of the first annular light source 3, the shadowless light source 4, the second annular light source 5, and the coaxial light source 6.

[0038] To improve the space utilization rate inside the housing 2, preferably, a second opening 71 and a third opening 81 are respectively provided in the middle of the first control circuit board 7 and the second control circuit board 8. The first control circuit board 7 and the second control circuit board 8 are hung on the outside of the coaxial light source 6 through the second opening 71 and the third opening 81. The shapes and calibers of the second opening 71 and the third opening 81 match the shape and outer diameter of the coaxial light source 6, so that the first control circuit board 7 and the second control circuit board 8 can be directly threaded through the outer surface of the coaxial light source 6, and bonding or detachable fixation can be achieved through glue or other connectors. This setting can effectively improve the space utilization rate and reduce the production cost.

[0039] As Figure 5 shown, the two-color temperature controllable lamp bead 9 of this embodiment includes a lamp bead body 91, a first lamp bead 92 and a second lamp bead 93 provided on the lamp bead body 91, and a first chip and a second chip (not shown in the figure) for controlling the first lamp bead 92 and the second lamp bead 93. A first lead 94 and a second lead 95 electrically connected to the first lamp bead 92 and the second lamp bead 93 are provided on the lamp bead body 91. The above-mentioned first lamp bead 92 and second lamp bead 93 are white lamp beads with one high color temperature and one low color temperature, that is, one of the first lamp bead 92 and the second lamp bead 93 is a high color temperature lamp bead with a color temperature above 5000K, and the other is a low color temperature lamp bead with a color temperature below 3500K.

[0040] In addition, preferably, the present application also reserves a structure for expanding other light sources. Specifically, the first control circuit board 7 is connected to an external panel 72. A number of reserved external power plugs 721 electrically connected to the first control circuit board 7 are provided on the external panel 72. A communication network port 73 is provided on the first control circuit board 7. The external panel 72 is fixedly connected to the end of the housing 2, and a first opening 722 matching the detection inlet 21 is provided on the external panel 72. A number of first connection holes 723 are provided on the external panel 72 for connection and cooperation with the subsequently added light sources. Furthermore, a second connection hole 724 is provided on the side edge of the external panel 72, and a third connection hole 25 matching the second connection hole 724 is provided on the top flank of the housing 2. By arranging the external panel 72 at the uppermost end of the housing 2 and cooperating with the reserved external power plugs 721 and the communication network port 73, more different light source modules can be connected as needed to meet the requirements of various functions, thereby improving the expandability of the present invention.

[0041] The present invention controls the start and stop of each component through the first control circuit board 7, and controls the current of the first chip and the second chip to adjust the light emission brightness of the two chips through the second control circuit board 8, so as to achieve the adjustment of the color temperature. Moreover, the light source modules of the present invention all use the above-mentioned two-color temperature controllable lamp beads 9 as light sources. In this way, each individual light source can be arbitrarily adjusted to the desired color temperature through the second control circuit board 8, and the application scenarios are more flexible and extensive. In addition, a reserved external light source port is added, and various light sources can be combined at will.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
