Description

Technical Field

[0001] This utility model relates to the technical field of light sources, and in particular to a focal length adjustable multi-angle linear light source and a combination of linear light sources. Background Technology

[0002] Currently, linear light sources are widely used in machine vision inspection. The light emitted by the LED beads on the light panel is divergent, leading to energy dispersion when directly illuminating the light source. For high-precision line scan inspection, deep hole / inner wall inspection, and high-speed moving object inspection, a focusing rod is often placed in the direction of illumination from the light panel. The focusing rod uses total internal reflection to convert the divergent light into a linear, high-density light band, increasing the light intensity by 3-5 times. Furthermore, the difference in light intensity between the edge and center of the formed light band is less than 5%, eliminating edge attenuation and meeting the illumination requirements for high-precision, high-speed, or deep hole inspection. However, the relative distance and angle between the light panel and the focusing rod in current linear light sources using focusing rods are not adjustable, resulting in low flexibility and an inability to quickly meet the application requirements of various illumination focal lengths and angles. Therefore, improvements to existing technology are necessary. Utility Model Content

[0003] This invention provides a focal length adjustable multi-angle linear light source and a combination of linear light sources, which mainly solves the technical problem that the existing linear light sources using a focusing rod have poor flexibility and cannot meet the needs of various application scenarios.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A focal length adjustable multi-angle linear light source includes a linear light panel, a spotlight rod, a mounting base, a lifting adjustment device, and a rotating device;

[0006] The linear light panel is fixed on the mounting base, and the focusing rod is fixed in the illumination direction of the linear light panel. The lifting adjustment device is connected to the rotating device, and the mounting base is connected to the lifting adjustment device or the rotating device. The lifting adjustment device is used to adjust the height of the mounting base relative to the focusing rod, and the rotating device is used to adjust the angle of the mounting base relative to the focusing rod. When the mounting base rotates relative to the focusing rod, the length of the linear light panel is always parallel to the axis of the focusing rod.

[0007] In one of the technical solutions, the lifting adjustment device, the rotating device, and the mounting base are connected in sequence, and the lifting adjustment device is used to simultaneously adjust the height of the rotating device and the mounting base relative to the focusing rod.

[0008] In one of the technical solutions, the lifting adjustment device includes a fixed base, a lifting base, and a hand-tightening screw. The fixed base is provided with a dovetail groove, which cooperates with the dovetail block of the lifting base. The dovetail groove extends longitudinally. The hand-tightening screw is connected to the side of the fixed base and is used to lock or unlock the lifting base. The rotating device is fixed on the lifting base.

[0009] In one of the technical solutions, the rotating device includes a base, a rotating seat, and a hand-tightening component; the base is fixed to the lifting seat, the rotating seat is rotatably connected to the base, and the rotation axis of the rotating seat relative to the base is parallel to the axis of the focusing rod; the hand-tightening component is connected to the base and is used to drive the rotating seat to rotate relative to the base; the mounting base is fixedly connected to the rotating seat.

[0010] In one of the technical solutions, the rotating device further includes a locking member, which is connected to the base and used to lock or unlock the rotating seat.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0026] It should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please refer to the following: Figures 1 to 3 This utility model provides a focal length adjustable multi-angle linear light source, including a linear light panel 1, a focusing rod 2, a mounting base 3, a lifting adjustment device 4, and a rotating device 5. The linear light panel 1 is fixed on the mounting base 3, and the focusing rod 2 is fixed in the illumination direction of the linear light panel 1, so that when the linear light panel 1 emits light, it can focus the light through the focusing rod 2 to form a bright light band. The lifting adjustment device 4 is connected to the rotating device 5. The mounting base 3 can be connected to the lifting adjustment device 4 or the rotating device 5. The lifting adjustment device 4 is used to adjust the height of the mounting base 3 relative to the focusing rod 2, thereby adjusting the height of the linear light panel 1 relative to the focusing rod 2, and thus adjusting the focal length of the light focused by the focusing rod 2. The rotating device 5... The 5th setting is used to adjust the angle of the mounting base 3 relative to the focusing rod 2, thereby adjusting the emission angle of the linear light panel 1 after passing through the focusing rod 2. Moreover, when the mounting base 3 rotates relative to the focusing rod 2, the length of the linear light panel 1 is always parallel to the axis of the focusing rod 2. In fact, since the focusing rod 2 is stationary while the position of the linear light panel 1 is movable, the shape of the focusing rod 2 is preferably cylindrical. This ensures that even if the position of the linear light panel 1 changes during the adjustment of the angle of the linear light panel 1, the cylindrical focusing rod 2 can still form a strip of high-brightness light under the illumination of the linear light panel 1. Furthermore, even if the position of the linear light panel 1 changes, the brightness of the light emitted by the linear light panel 1 and focused by the focusing rod 2 remains almost unchanged.

[0030] Specifically, this solution allows adjustment of the angle between the linear light panel 1 and the focusing rod 2 by operating the rotating device 5, and adjustment of the height of the linear light panel 1 relative to the focusing rod 2 by operating the lifting adjustment device 4. In other words, this solution allows for adjustment of the relative position and rotation angle between a single linear light panel 1 and the focusing rod 2, thereby achieving different illumination angles and focal lengths. This provides high flexibility and helps meet the needs of various application scenarios. Especially for example... Figure 4 As shown, when multiple linear light sources 10 are used in combination, different effects with multiple angles, focal lengths, and colors can be flexibly achieved, making it more flexible to use and suitable for a wider range of application scenarios.

[0031] Please refer to them again. Figures 1 to 3The lifting adjustment device 4, the rotating device 5, and the mounting base 3 are connected in sequence. That is, when the lifting adjustment device 4 is operated, the lifting adjustment device 4 simultaneously adjusts the height of the rotating device 5, the mounting base 3, and the linear lamp plate 1 relative to the focusing rod 2. In other embodiments, the rotating device 5, the lifting adjustment device 4, and the mounting base 3 can also be designed to be connected in sequence. In this embodiment, when the rotating device 5 is operated, the lifting adjustment device 4, the mounting base 3, and the linear lamp plate 1 will rotate synchronously together.

[0032] Please refer to them again. Figures 1 to 3 The lifting adjustment device 4 preferably includes a fixed base 41, a lifting base 42, and a hand-tightening screw 43. The fixed base 41 and the focusing rod 2 are fixed relative to each other. One of the fixed base 41 and the lifting base 42 is provided with a dovetail groove 411, and the other is provided with a dovetail block 421 that cooperates with the dovetail groove 411. The dovetail cooperation method has the advantage of low cost. The dovetail groove 411 extends longitudinally, so that the lifting base 42 can be adjusted in the longitudinal direction relative to the fixed base 41. The hand-tightening screw 43 is connected to the side of the fixed base 41. When the hand-tightening screw 43 abuts against the outer wall of the lifting base 42, the hand-tightening screw 43 can lock the position of the lifting base 42 to prevent the lifting base 42 from sliding down automatically. When the hand-tightening screw 43 is turned outward, the lifting base 42 can be unlocked. At this time, the lifting base 42 can be adjusted in the longitudinal direction relative to the fixed base 41. The aforementioned rotating device 5 is fixed on the lifting base 42 to enable the joint adjustment of the height of the rotating device 5, the mounting base 3 and the linear lamp plate 1, thereby adjusting the focal length of the light emitted by the linear lamp plate 1 after being focused by the focusing rod 2.

[0033] Please refer to them again. Figures 1 to 3 The rotating device 5 specifically includes a base 51, a rotating seat 52, and a hand-tightening component 53. The base 51 is fixed to the aforementioned lifting seat 42, and the rotating seat 52 is rotatably connected to the base 51. The rotation axis of the rotating seat 52 relative to the base 51 is parallel to the axis of the focusing rod 2. Figure 1 or Figure 3Taking the perspective of the rotating base 52 as an example, the rotation axis of the rotating base 52 relative to the base 51 and the axis of the focusing rod 2 both point in the horizontal direction. The hand-tightening component 53 is connected to the base 51 and is used to drive the rotating base 52 to rotate relative to the base 51. The aforementioned mounting base 3 is fixedly connected to the rotating base 52. When the hand-tightening component 53 is operated to drive the rotating base 52 to rotate, the mounting base 3 and the linear light panel 1 can be driven to rotate together to achieve the function of adjusting the angle of the linear light panel 1 relative to the focusing rod 2. In addition, the rotating device 5 also includes a locking component 54, which is preferably a screw. When the locking component 54 abuts against the outer wall of the rotating base 52, the locking component 54 can lock the position of the rotating base 52 to prevent the rotating base 52 from rotating automatically. When the locking component 54 is screwed outward, the rotating base 52 can be unlocked, and at this time the rotating base 52 can rotate relative to the base 51.

[0034] Please refer to them again. Figures 1 to 3 The mounting base 3 has an arc surface 31 on the side facing away from the linear lamp panel 1. The arc of the arc surface 31 is a superior arc. The arc surface 31 has multiple heat dissipation parts 32 protruding upward. By setting the arc surface 31, it is beneficial to increase the number of heat dissipation parts 32, thereby increasing the contact area between the mounting base 3 and the outside air, and thus improving the heat dissipation performance of the mounting base 3 and the linear lamp panel 1.

[0035] Please see Figure 4 This application also provides a linear light source combination, which includes multiple of the above-mentioned focal length adjustable multi-angle linear light sources 10. When multiple linear light sources 10 are used in combination, the illumination angle and illumination focal length of each linear light source 10 can be flexibly adjusted to achieve different effects with multiple angles, multiple focal lengths, and multiple colors. This makes it more flexible to use and more suitable for various application scenarios.

[0036] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
