Description

Technical Field

[0001] This utility model relates to the field of light sources, and in particular to a light source device with an adjustable angle for detection. Background Technology

[0002] When using an industrial camera to photograph and inspect an object, it is necessary to use a light source to illuminate the object. To obtain better imaging results, it is often necessary to adjust the angle of the light to accurately capture the defects of the object.

[0003] Traditional adjustment methods involve rotating the light source around a metal rod. Once the desired angle is reached, the angle is fixed by tightening the handle. This structure, where the light source extends a certain distance beyond the metal rod, makes the light source unstable, causing it to wobble and affecting the accuracy of the light's illumination angle.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a light source device with adjustable angle for detection, so as to solve the problem that the structure of the light source device in the prior art is unstable, which will cause shaking and affect the accuracy of the light illumination angle.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An angle-adjustable light source device for detection;

[0008] Includes: a first mounting plate; a second mounting plate; a fixed gear, respectively fixedly mounted in the first mounting plate and the second mounting plate at close proximity to each other; a mounting block, located between the first mounting plate and the second mounting plate; a movable gear, rotatably mounted on the mounting block; and a light source, respectively mounted on the first mounting plate and the second mounting plate.

[0009] The movable gear meshes with the fixed gear on the first mounting plate and the fixed gear on the second mounting plate respectively; the mounting block rotatably connects the first mounting plate and the second mounting plate respectively, and the first mounting plate and the second mounting plate rotate to form an included angle.

[0010] A further technical solution is that notches are formed in the first mounting plate and the second mounting plate at positions close to each other; a mounting shaft is provided in the notch; and the fixed gear is mounted on the mounting shaft.

[0011] A further technical solution is that the mounting block extends into the first mounting plate and the second mounting plate respectively; the extension is rotatably connected to the mounting shaft.

[0012] A further technical solution is that the movable gear is a helical gear; the fixed gear is a helical gear.

[0013] A further technical solution is that the mounting block is equipped with a power device; the drive end of the power device is connected to the movable gear.

[0014] A further technical solution is that the first mounting plate and the second mounting plate can be straight plates or curved plates.

[0015] A further technical solution is that the light source includes a substrate and LED beads arranged side by side on the substrate; the first mounting plate and the second mounting plate form a mounting groove with their sides close to each other; the substrate is placed in the mounting groove, and the LED beads protrude from the mounting groove.

[0016] A further technical solution includes an elastic device; hooks are formed on the first mounting plate and the second mounting plate; and the two ends of the elastic device are respectively hung on the hooks.

[0017] A further technical solution is that the first mounting plate and the second mounting plate are provided with limiting grooves; the elastic device is placed in the limiting grooves.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (1) By turning the movable gear, the movable gear drives the first mounting plate and the second mounting plate to swing through the meshing between the movable gear and the fixed gear, so that the power transmission between the movable gear and the fixed gear is smooth and the first mounting plate and the second mounting plate will not shake when swinging; the light source is installed on the first mounting plate and the second mounting plate respectively, and the light source shines on the defect position of the object to be inspected, which can be clearer; at the same time, the light source is installed separately on the first mounting plate and the second mounting plate, which shortens the size of the first mounting plate and the second mounting plate and avoids the shaking of the first mounting plate and the second mounting plate.

[0019] (2) Both the fixed gear and the mounting shaft are installed in the notch. When the first mounting plate and the second mounting plate swing, the fixed gear on the first mounting plate and the fixed gear on the second mounting plate will not interfere with each other, and the irradiation angle can be smoothly adjusted.

[0020] (3) The elastic device exerts a continuous pulling force on the first mounting plate and the second mounting plate. When the first mounting plate and the second mounting plate swing, the mounting block and the first mounting plate, as well as the mounting block and the second mounting plate, always fit together to avoid gaps, which would cause the first mounting plate and the second mounting plate to shake and affect the light irradiation effect.

It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model.

[0026] First embodiment:

[0027] Figure 1 A schematic diagram of the structure of the angle-adjustable light source device for detection according to the first embodiment of this utility model is shown. Figure 2 It shows Figure 1 A magnified structural diagram at point A. (Combined with...) Figure 1 and Figure 2 As shown, this utility model discloses a light source device with adjustable angle for detection.

[0028] The detection angle-adjustable light source device includes: a first mounting plate 1, a second mounting plate 2, a fixed gear 3, a mounting block 4, a light source 6, and a movable gear 5 rotatably mounted on the mounting block 4.

[0029] Among them, the fixed gears 3 are in two sets, which are respectively fixedly installed in the first mounting plate 1 and the second mounting plate 2 at close proximity to each other.

[0030] Mounting block 4 is located between the first mounting plate 1 and the second mounting plate 2. Mounting block 4 is rotatably connected to the first mounting plate 1 and the second mounting plate 2 respectively. The first mounting plate 1 and the second mounting plate 2 swing along both ends of mounting block 4 to form an included angle.

[0031] The light source 6 is respectively set on the first mounting plate 1 and the second mounting plate 2. When the first mounting plate 1 and the second mounting plate 2 swing, the illumination angle of the light source 6 is adjusted.

[0032] The movable gear 5 meshes with the fixed gear 3 on the first mounting plate 1 and the fixed gear 3 on the second mounting plate 2. Turning the movable gear 5 causes it to rotate, and through the meshing of the movable gear 5 and the fixed gear 3, the movable gear 5 drives the first mounting plate 1 and the second mounting plate 2 to swing, ensuring smooth power transmission between the movable gear 5 and the fixed gear 3, and preventing any wobbling when the first mounting plate 1 and the second mounting plate 2 swing. The light source 6 is mounted on the oppositely positioned first mounting plate 1 and the second mounting plate 2, illuminating the defect location of the object to be inspected more clearly. Simultaneously, the separate mounting of the light source 6 on the first mounting plate 1 and the second mounting plate 2 shortens the size of the first mounting plate 1 and the second mounting plate 2, preventing wobbling.

[0033] Notches 7 are formed in close proximity within the first mounting plate 1 and the second mounting plate 2. A mounting shaft 71 is disposed within the notch 7. A fixed gear 3 is mounted on the mounting shaft 71.

[0034] Both the fixed gear 3 and the mounting shaft 71 are installed in the notch 7. When the first mounting plate 1 and the second mounting plate 2 swing, the fixed gear 3 on the first mounting plate 1 and the fixed gear 3 on the second mounting plate 2 will not interfere with each other, and the irradiation angle can be smoothly adjusted.

[0035] Mounting block 4 extends 41 to the first mounting plate 1 and the second mounting plate 2 respectively. Extension 41 is located at both ends of fixed gear 3. Extension 41 is rotatably connected to mounting shaft 71, mounting shaft 71 passes through extension 41, and extension 41 provides support for mounting shaft 71.

[0036] When the first mounting plate 1 and the second mounting plate 2 swing, the mounting shaft 71 rotates within the extension 41, so that the first mounting plate 1 and the second mounting plate 2 can swing smoothly.

[0037] For example, the movable gear 5 is a helical gear. For example, the fixed gear 3 is a helical gear.

[0038] The movable gear 5 is mounted on the mounting block 4 in the up-down direction, and the fixed gear 3 is mounted on the first mounting plate 1 in the front-back direction. The fixed gear 3 is also mounted on the second mounting plate 2 in the front-back direction. The driving force of the movable gear 5 needs to be changed to transmit to the fixed gear 3 to realize the swing of the first mounting plate 1 and the second mounting plate 2. The direction of the driving force transmission can be changed by the helical gear.

[0039] For example, the power unit 42 is an electric motor. The power unit 42 is mounted on the mounting block 4, and the drive end of the power unit 42 is connected to the movable gear 5. Power is provided by the power unit 42 driving the movable gear 5 to complete the automatic adjustment of the illumination angle of the angle-adjustable light source device for detection.

[0040] Depending on the application scenario, the first mounting plate 1 and the second mounting plate 2 can be straight plates or curved plates.

[0041] The light source 6 includes a substrate 61 connected to a power source and LED beads 62 arranged side-by-side on the substrate 61. A mounting groove 72 is formed on one side of a first mounting plate 1 and a second mounting plate 2 that are close to each other. The substrate 61 is placed in the mounting groove 72, such that the LED beads 62 are arranged on the first mounting plate 1 and the second mounting plate 2 respectively.

[0042] If the LED 62 is placed inside the mounting slot 72, the irradiated light will be a straight line after being restricted by the mounting slot 72, resulting in blind spots. Because the LED 62 protrudes from the mounting slot 72, the light produced by the LED 62 is diffused, and there are no blind spots between adjacent LEDs 62, resulting in uniform light distribution.

[0043] Second embodiment:

[0044] Figure 3 A schematic diagram of the structure of the angle-adjustable light source device for detection according to the second embodiment of this utility model is shown. (Combined with...) Figures 1-3 As shown, the angle-adjustable light source device for detection also includes an elastic device 8. For example, the elastic device 8 is a spring. Hooks 73 are formed on the side of the first mounting plate 1 and the second mounting plate 2 away from the light source 6. Both ends of the elastic device 8 are respectively hung on the hooks 73. The elastic device 8 exerts a continuous pulling force on the first mounting plate 1 and the second mounting plate 2. When the first mounting plate 1 and the second mounting plate 2 swing, the mounting block 4 and the first mounting plate 1, and the mounting block 4 and the second mounting plate 2, remain in contact, preventing gaps that could cause the first mounting plate 1 and the second mounting plate 2 to wobble and affect the light illumination effect.

[0045] A limiting groove 74 is provided on the side of the first mounting plate 1 and the second mounting plate 2 away from the light source 6. The end of the limiting groove 74 near the hook 73 transitions into the surface of the first mounting plate 1. The elastic device 8 is placed in the limiting groove 74, which restricts the position of the elastic device 8 and prevents it from detaching from the first mounting plate 1 and the second mounting plate 2, so that the elastic device 8 can continuously generate tension.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
