Description

Technical Field

[0001] This utility model relates to the technical field of light sources for machine vision inspection, and more particularly to a flexible combination of lighting devices. Background Technology

[0002] With the rapid development of technology, the demand for workpiece inspection using machine vision technology is increasing. Machine vision technology mainly consists of a processor, camera, and light source. During operation, the light source illuminates the workpiece to ensure the camera can capture a bright image. The processor then analyzes the image information and derives the corresponding inspection results. Current surface light sources or ring light sources can meet most lighting needs. However, if the shape or size of the workpiece changes, users usually need to purchase additional lighting devices of different sizes. However, placing multiple sizes of lighting devices occupies a lot of space and cannot meet the need for flexible lighting of workpieces of different sizes in a small space. Therefore, improvements to existing lighting devices are necessary. Utility Model Content

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

[0005] A flexible combination lighting device is used in the field of machine vision inspection to illuminate the object being inspected. The lighting device includes multiple magnetic bases and multiple light sources. The emission angle and emission color of the light sources are selectable. The light sources can be magnetically attached to any one of the magnetic bases.

[0006] Each of the magnetic bases includes a base body and a first track and a second track, both conductive, fixed to the base body. The first track is used to connect to the positive terminal of a power supply, and the second track is used to connect to the negative terminal of a power supply. Each of the light sources includes a light source body and a positive and a negative component, both conductive, fixed to the light source body. The positive component is electrically connected to the positive terminal of the light source body, and the negative component is electrically connected to the negative terminal of the light source body. When the light source is magnetically attracted to one of the magnetic bases, the positive component is magnetically attracted to the first track, and the negative component is magnetically attracted to the second track.

[0007] In one of the technical solutions, at least one of the positive electrode component and the first track is a conductive magnet, and at least one of the negative electrode component and the second track is a conductive magnet.

[0008] In one of the technical solutions, the positive electrode component, the first track, the negative electrode component, and the second track are all carbon steel magnet components.

[0009] In one of the technical solutions, the light source body includes a lower shell, an upper shell, a lamp panel, and a lens;

[0010] The upper shell and the lower shell are joined together to form a receiving cavity. The lamp plate and the lens are housed in the receiving cavity. The side of the lower shell facing away from the upper shell is provided with a first through hole for accommodating the positive electrode component and a second through hole for accommodating the negative electrode component. The positive electrode component is electrically connected to the positive electrode of the lamp plate, and the negative electrode component is electrically connected to the negative electrode of the lamp plate. The side of the upper shell facing away from the lower shell is provided with a light-emitting hole. The light-emitting surface of the lamp plate faces the light-emitting hole, and the lens is disposed between the lamp plate and the light-emitting hole.

[0011] In one of the technical solutions, the upper shell and the lower shell are detachably connected, and the lamp panel and the lens are both detachably connected relative to the upper shell or the lower shell.

[0012] In one of the technical solutions, the upper shell and the lower shell are connected by a snap-fit ​​connection.

[0013] In one of the technical solutions, the lighting device further includes a splicing component, which is used to connect two adjacent magnetic bases in series.

[0015] In one of the technical solutions, a limiting groove for embedding the light source is provided on the surface of the base body. The bottom of the limiting groove is provided with a first groove and a second groove arranged at intervals. The first track is received in the first groove and the second track is received in the second groove.

[0016] In one of the technical solutions, both the bottom of the first groove and the bottom of the second groove are provided with through mounting holes.

[0017] In one of the technical solutions, multiple magnetic bases are arranged along a first direction, and both the first track and the second track extend in a second direction, with the first direction and the second direction being perpendicular to each other.

[0019] In use, this solution allows users to arrange the number and position of magnetic bases according to the shape or size of the workpiece being inspected. For example, for workpieces with a general shape such as square or round, multiple magnetic bases can be arranged in parallel along the Y direction. Then, according to the required lighting range and intensity, the light source is magnetically attached to the appropriate position on each magnetic base. When the magnetic base is connected to an external power source, the first and second tracks on the magnetic base will create a conductive loop for the corresponding light source to illuminate the workpiece. Each light source can be adjusted in the X direction. In other words, this solution allows for flexible adjustment of lighting in both the X and Y directions. Users can quickly illuminate workpieces of various shapes and sizes without needing to purchase lighting devices of different sizes, saving indoor space and improving the user experience.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] 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.

[0031] Please refer to the following: Figure 1 This utility model embodiment provides a flexible combination lighting device for use in the field of machine vision inspection to illuminate the object being inspected. The lighting device mainly includes multiple magnetic bases 1 and multiple light sources 2. The emission angle and emission color of the light sources 2 are selectable. For example, the emission angle of the light sources 2 can be selected as 30°, 60°, 90°, 120°, 150° or 180°, etc., and the emission color of the light sources 2 can be selected as white, warm white, yellow, green, blue and red. In this embodiment, the light sources 2 can be magnetically attached to any one of the magnetic bases 1.

[0032] Specifically, each magnetic base 1 includes a base body 11, a first track 12 and a second track 13. The first track 12 and the second track 13 are both fixed on the base body 11. Moreover, the first track 12 and the second track 13 are both conductive. The first track 12 is used to connect to the positive terminal of an external power source, and the second track 13 is used to connect to the negative terminal of an external power source.

[0033] More specifically, each light source 2 includes a light source body 21, a positive electrode component 22, and a negative electrode component 23. Both the positive electrode component 22 and the negative electrode component 23 are fixed to the bottom of the light source body 21. Both the positive electrode component 22 and the negative electrode component 23 are conductive; the positive electrode component 22 is electrically connected to the positive electrode of the light source body 21, and the negative electrode component 23 is electrically connected to the negative electrode of the light source body 21. When the light source 2 is magnetically attracted to one of the magnetic bases 1, the positive electrode component 22 is actually magnetically attracted to the first track 12, and the negative electrode component 23 is magnetically attracted to the second track 13. Since the positive electrode component 22, the negative electrode component 23, the first track 12, and the second track 13 are all conductive, when the first track 12 and the second track 13 are respectively connected to an external power source, a conductive circuit is formed between the light source body 21 and the external power source, thus illuminating each light source body 21 magnetically attracted to the magnetic base 1.

[0034] In this preferred embodiment, the positive electrode component 22, the first track 12, the negative electrode component 23, and the second track 13 are all carbon steel magnet components. The carbon steel magnet has both magnetic and conductive properties, so that the positive electrode component 22 can be magnetically attracted to the first track 12 and conduct electricity, and the negative electrode component 23 can be magnetically attracted to the second track 13 and conduct electricity.

[0035] In other embodiments, one of the positive electrode component 22 and the first track 12 is a conductive carbon steel magnet, while the other is designed as a metal component. In this case, the positive electrode component 22 and the first track 12 can still achieve the function of magnetic attraction and conduction. Similarly, one of the negative electrode component 23 and the second track 13 is a conductive carbon steel magnet, while the other is designed as a metal component. In this case, the negative electrode component 23 and the second track 13 can also achieve the function of magnetic attraction and conduction.

[0036] Specifically, in use, the user can arrange the number and position of the magnetic bases 1 according to the shape or size of the workpiece being inspected. For example, for workpieces with a conventional shape such as square or round, multiple magnetic bases 1 can be arranged in parallel along the first direction (Y direction). Then, according to the actual required lighting range and intensity, the light source 2 is magnetically attached to the appropriate position of each magnetic base 1. When the magnetic base 1 is connected to an external power source, the first track 12 and the second track 13 on the magnetic base 1 will allow the corresponding light source 2 to form a conductive circuit to illuminate the workpiece being inspected. Both the first track 12 and the second track 13 are directed towards the first... Extending in two directions (X and Y directions perpendicular to each other), each light source 2 can be adjusted in position along the second direction (X direction). In other words, this solution can flexibly adjust the lighting in both the X and Y directions. When using it, even when facing workpieces of various shapes or sizes, users can quickly achieve the function of lighting the workpieces to be inspected. Users no longer need to purchase lighting devices of various sizes, saving indoor space and improving the user experience. Moreover, the light source 2 in this solution can also select different light colors and emission angles to more flexibly meet more inspection needs, thereby further improving the user experience.

[0037] In one embodiment, the lighting device may further include a splicing element (not shown in the figure) that connects two adjacent magnetic bases 1 in series. In this case, only one magnetic base 1 needs to be connected to an external power source, and all magnetic bases 1 can then be connected to the power source, thus simplifying wiring and improving tidiness. Specifically, the splicing element can be used to extend the length of the magnetic base 1 in the second direction (i.e., the X-direction), thereby meeting the lighting requirements for visual inspection of larger objects. When two adjacent magnetic bases 1 are connected in series using a splicing element, the first tracks 12 on the two adjacent magnetic bases 1 are actually connected through one splicing element, and the second tracks 13 on the two adjacent magnetic bases 1 are connected through another splicing element.

[0038] Please refer to it again. Figure 1A limiting groove 111 is provided on the surface of the base body 11. The width of the limiting groove 111 in the second direction (Y direction) is adapted to the external dimensions of the light source 2, so that the light source 2 can be embedded in the limiting groove 111. In addition, the bottom of the limiting groove 111 has a first groove 112 and a second groove 113 arranged at intervals. The first track 12 is received in the first groove 112, and the second track 13 is received in the second groove 113. This design can play a role in preventing foolproof installation, preventing the light source 2 from being magnetically attracted to the first track 12 of one of the magnetic bases 1 and then mistakenly attracted to the first track 12 of the adjacent magnetic base 1 (which would cause a short circuit), thereby preventing short circuits and improving the safety of the user assembling the light source 2. In addition, by providing the limiting groove 111, the position of the light source 2 can also be restricted, so that the position of the light source 2 can be adjusted more precisely along the second direction (Y direction). Preferably, the bottom of the first groove 112 and the bottom of the second groove 113 are provided with through mounting holes 114, so that the user can fix the magnetic base 1 in a designated position by passing screws through the mounting holes 114.

[0039] Please refer to the following: Figure 1 and Figure 2 The light source body 21 specifically includes a lower shell 211, an upper shell 212, a lamp plate 213, and a lens 214. The upper shell 212 and lower shell 211 are joined together to form a receiving cavity, within which the lamp plate 213 and lens 214 are housed. The lower shell 211 has a first through hole 2111 and a second through hole 2112 on the side facing away from the upper shell 212 (which can be understood as the bottom surface of the lower shell 211). The positive electrode component 22 is housed within the first through hole 2111, and the negative electrode component 23 is housed within the second through hole 2112. In fact, the positive electrode component 22 and... The positive terminal of the lamp board 213 is electrically connected, and the negative terminal component 23 is electrically connected to the negative terminal of the lamp board 213. The lamp board 213 can be understood as a circuit board with LED beads. The side of the upper shell 212 facing away from the lower shell 211 (which can be understood as the top surface of the upper shell 212) is provided with a through light-emitting hole 2121. The light-emitting surface of the lamp board 213 faces the light-emitting hole 2121 so that it can emit light to the outside. The lens 214 is disposed between the lamp board 213 and the light-emitting hole 2121. The lens 214 is used to change the light-emitting angle of the lamp board 213 so that the lamp board 213 emits light to the outside at a specified angle. Preferably, the upper shell 212 and the lower shell 211 are designed to be detachably connected, and the lamp panel 213 and the lens 214 are also designed to be detachably connected relative to the upper shell 212 or the lower shell 211. With this design, the manufacturer can quickly install the lamp panel 213 with the required light color and the lens 214 with the required light emission angle into the lower shell 211. Of course, the user can also replace the internal lamp panel 213 and lens 214, thereby quickly meeting the user's needs for the light source 2 with a specified light color and a specified light emission angle.

[0040] 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.
