[0002] In different detection scenarios, it is necessary to irradiate the workpiece to be measured with light of different colors. Currently, the color is mainly switched by replacing the filter. For example, when it is necessary to irradiate the workpiece to be measured with green light, a green filter is fixed at the light-emitting surface of the light source device; when it is necessary to irradiate the workpiece to be measured with red light, the original green filter needs to be removed first, and then a red filter is reinstalled at the light-emitting surface of the light source device. Workshop workers often need to install and remove the filter, which is very inconvenient and the production efficiency is low.

[0003] Therefore, it is necessary to improve the existing light source device to solve the problem of low production efficiency caused by inconvenient filter switching.

[0047] The present invention provides a switchable light source device, which is applicable to the application scenario of irradiating a workpiece to complete visual inspection, and can effectively solve the problem of low production efficiency caused by inconvenient filter switching of the existing light source device.

[0048] See Figure 1 , the switchable light source device provided in this embodiment includes a light source body 1, a filter plate 2, and a light shielding plate 3.

[0049] The filter plate 2 is fixedly arranged relative to the light source body 1; see Figure 2 , wherein, at least two groups of filter components are provided on the filter plate 2; optionally, each group of filter components is provided with a number of filter plates with different filter parameters such as filter wavelengths, and the filter parameters of the filter plates in different groups are different, so as to meet different lighting requirements;

[0050] See Figure 3 , the light shielding plate 3 includes a light-transmitting area 301 and a light-shielding area 302; correspondingly, the light-transmitting area 301 is a number of light-transmitting holes.

[0051] The light shielding plate 3 is movably installed on the light source body 1, and there are at least two different installation states on the light source body 1 so that the light-transmitting area 301 is aligned with different filter components. When the light-transmitting area 301 of the light shielding plate 3 faces any group of the filter components, all the remaining filter components of the filter plate 2 face the light-shielding area 302 of the light shielding plate 3, so the light source body 1 can only emit light outward through the filter components facing the light-transmitting area 301 and irradiate the workpiece to be measured.

[0052] In the switchable light source device provided in this embodiment, the shading plate 3 is movably mounted on the light source body 1. When it is necessary to use light of different colors to illuminate the workpiece to be measured, it is not necessary to remove the entire filter plate 2. It is only necessary to switch the shading plate 3 to different positions so that the light-transmitting area 301 is aligned with different filter components. For example, when the shading plate 3 is installed to the left of the light source body 1, the light-transmitting area 301 is aligned with the green filter component, and the green light can be used to illuminate the workpiece; when the shading plate 3 is installed to the right of the light source body 1, the light-transmitting area 301 is aligned with the red filter component, and the red light can be used to illuminate the workpiece.

[0053] The switchable light source device provided by the utility model does not need to disassemble and reassemble the filter assembly when the light color needs to be changed. It only needs to switch the shading plate 3 to a different position. The operation is simple and convenient, so it can effectively solve the problem of low production efficiency caused by the inconvenience of switching the filter of the existing light source device.

[0054] In this embodiment, the light source body 1 includes a light source housing 101, a lamp board 102, and a diffuser plate 103. The light source housing 101 is provided with a receiving cavity with an opening facing upward; the lamp board 102 and the diffuser plate 103 are both located in the receiving cavity, and the lamp board 102 is located on the side of the diffuser plate 103 away from the filter assembly. The light emitted by the lamp board 102 is diffused by the diffuser plate 103, passes through the light-transmitting area 301 and the filter assembly aligned with the light-transmitting area 301, and then emits light outward to illuminate the workpiece to be measured.

[0055] In this embodiment, the filter plate 2 is fastened to the light source housing 101 by means of a locking bolt 6. The filter plate 2 is provided with a long hole 303 for the locking bolt 6 to pass through. By loosening the locking bolt 6, the filter plate 2 can be moved left and right, thereby aligning the light-transmitting area 301 with different filter components.

[0056] In this embodiment, there are two groups of the filter components (hereinafter referred to as “the first filter component 201 ” and the “second filter component 202 ”), and the filters of the two groups of the filter components are arranged at intervals along the length direction of the long hole 303 .

[0057] When the locking bolt 6 abuts against the inner wall of one end of the long hole 303, each of the light-transmitting holes is aligned with each of the filters of the first filter assembly 201, and green light can be used to illuminate the workpiece at this time;

[0058] When the locking bolt 6 abuts against the inner wall of the other end of the long hole 303, each of the light-transmitting holes is aligned with each of the filters of the second filter assembly 202, and red light can be used to illuminate the workpiece at this time.

[0059] In some other embodiments, two fixed magnetic members 4 (for example, both of the two fixed magnetic members 4 are magnets) may be provided on the light source housing 101 at intervals, and a movable magnetic member 5 (for example, the movable magnetic member 5 is a magnet or an iron block) may be provided on the light shielding plate 3;

[0060] When the movable magnetic member 5 is magnetically positioned with one of the fixed magnetic members 4, each of the light-transmitting holes is aligned with each of the filter sheets of the first filter assembly 201; when the movable magnetic member 5 is magnetically positioned with the other fixed magnetic member 4, each of the light-transmitting holes is aligned with each of the filter sheets of the second filter assembly 202. The alignment operation of the light-transmitting holes and the filter sheets is achieved by magnetic positioning, which is simple and convenient, and is beneficial to further improving the operation convenience and reducing the time required for switching the filter sheets.

[0061] In summary, the switchable light source device provided in this embodiment has the following advantages: The light shielding plate 3 is movably installed on the light source body 1. When it is necessary to irradiate a workpiece to be measured with light of different colors, it is not necessary to disassemble the entire filter plate 2. It is only necessary to switch the light shielding plate 3 to different positions so that the light-transmitting area 301 is aligned with different filter assemblies. When it is necessary to change the light output color, it is not necessary to disassemble and reassemble the filter assembly. It is only necessary to switch the light shielding plate 3 to different positions, and the operation is simple and convenient. Therefore, the problem that the existing light source device has low production efficiency due to inconvenient switching of the filter sheets can be effectively solved.

[0062] Finally, it should be noted that although the above embodiments have been described in the text of the specification and drawings of the present application, the patent protection scope of the present application cannot be limited thereby.
