Description

Technical Field

[0001] This utility model relates to the field of spliced ​​backlight technology for visual inspection, and more particularly to a spliced ​​backlight for visual inspection. Background Technology

[0002] A backlight for visual inspection is a lighting device used in machine vision inspection systems. By placing the light source behind the object to be inspected, it provides uniform background light, thereby helping the vision system to more clearly identify the outline, defects, or features of the object. The design of the modular backlight allows users to flexibly adjust the size and shape of the light source according to their inspection needs.

[0003] A typical spliced ​​backlight for visual inspection consists of a light source assembly, a support mechanism, and a light guide plate. Therefore, the light source assembly is the core part of the backlight when in use. It is usually composed of multiple light-emitting diodes (LEDs). These point light sources are converted into uniform surface light sources through the action of the light guide plate. The support mechanism is used to fix and support the light source assembly, and the light guide plate is used to distribute the light emitted by the light source evenly on the entire light-emitting surface of the backlight.

[0004] However, some existing devices cannot provide good stability and connectivity when spliced ​​together. This not only affects the overall performance of the backlight, but also leads to loosening and insecure splicing during use, resulting in inaccurate detection. Therefore, a spliced ​​backlight for visual inspection is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a spliced ​​backlight for visual inspection, which aims to improve the problem that some existing devices cannot provide good stability when spliced ​​together.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A splicing backlight for visual inspection includes a support plate, an assembly mechanism is provided on the outside of the support plate, a placement slot is provided on the outside of the assembly mechanism, and a rotation mechanism is provided inside the placement slot.

[0008] The combined mechanism includes multiple connecting rods, the external parts of which are slidably connected to the inside of the support plate. A sliding plate is fixedly connected to the bottom of the support plate. Two combined plates are fixedly connected to the external parts of the connecting rods and the sliding plate. Two connecting plates are fixedly connected to the external parts of the connecting rods and the sliding plate. A sliding groove is provided at the bottom of the support plate. A locking component for locking is fixedly connected inside the combined plate.

[0011] As a further description of the above technical solution:

[0012] The locking assembly includes two support columns, the outer sides of which are fixedly connected to the interior of the combined plate. The outer sides of the support columns are respectively fixedly connected to the front and rear sides of the interior of the combined plate. A locking plate is rotatably connected to the outer sides of the two support columns. A guide column is fixedly connected to the bottom of the locking plate. A spring is sleeved on the outer side of the guide column. The bottom of the spring is fixedly connected to the inner wall of the combined plate. A toggle lever is fixedly connected to one side of the locking plate. Two locking blocks are fixedly connected to the outer side of the connecting plate. The outer sides of the locking blocks are slidably connected to the interior of the combined plate.

[0013] As a further description of the above technical solution:

[0014] The rotating mechanism includes an alignment block, the outside of which is slidably connected to the inside of the placement groove, and a connecting column is fixedly connected to the outside of the alignment block, i.e., the side away from the placement groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the design of the sliding plate and the connecting rod, the combined plate and the connecting plate can be quickly slid into the support plate to realize the rapid splicing of the backlight. The sliding of the sliding plate in the sliding groove can effectively prevent the offset during the splicing process, ensuring the accuracy and stability of the splicing, thereby improving the splicing efficiency and the flexibility of operation.

[0023] 2. In this utility model, the angle adjustment of the backlight becomes simple and efficient through the linkage design of the rotating shaft and the connecting column. When the support plate is pressed, the rotating shaft rotates smoothly under the support of the support plate, thereby driving the connecting column and the alignment block to slide and rotate in the placement groove, so as to realize the angle adjustment of the backlight. This design is not only convenient to operate, but also ensures the accuracy of the angle adjustment, meeting the needs of different visual inspection scenarios. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7 The present invention provides an embodiment of a splicing backlight for visual inspection, including a support plate 1, which is designed to provide good support capabilities. The support plate 1 is provided with a combination mechanism 2 on its exterior, and the combination mechanism 2 is provided with a placement groove 3 on its exterior. The placement groove 3 is provided with a rotating mechanism 4 inside its interior.

[0035] The combined mechanism 2 includes multiple connecting rods 21, designed to provide good sliding ability, allowing them to slide inside the support plate 1. The connecting rods 21 are externally slidably connected to the inside of the support plate 1. A sliding groove 25 is provided at the bottom of the support plate 1, designed to provide good sliding space. A sliding plate 22 is fixedly connected to the bottom of the support plate 1, designed to provide good sliding ability, allowing it to slide inside the sliding groove 25. Two combined plates 23 are fixedly connected externally to the connecting rods 21 and the sliding plate 22, designed to provide good extension capacity. The sliding of the connecting rods 21 and the sliding plate 22 can drive the combined plates 23 to move relative to the support plate 1. The connecting rod 21 and the sliding plate 22 are externally fixedly connected to two connecting plates 24. These plates are designed to allow the adjacent side of the combined plate 23 to fit against the support plate 1, providing good flexibility. The combined plate 23 is internally fixedly connected to a locking assembly, which includes two support columns 29. These support columns 29 are designed to provide good support. The outer sides of the two support columns 29 are fixedly connected to the interior of the combined plate 23, and the outer sides of the support columns 29 are respectively fixedly connected to the front and rear sides of the interior of the combined plate 23. A locking plate 28 is rotatably connected to the outer sides of the two support columns 29. The support provided by the support columns 29 allows the locking plate 28 to provide good support. The card plate 28 has good rotational capability. A guide post 26 is fixedly connected to the bottom of the card plate 28, providing excellent guiding ability. A spring 27 is sleeved on the outside of the guide post 26, providing good elasticity. The downward pressure of the spring 27 allows the card plate 28 to be pressed down and lifted. Simultaneously, the spring 27 prevents displacement during compression and reset. The bottom of the spring 27 is fixedly connected to the inner wall of the combination plate 23. A lever 210 is fixedly connected to the outer side of the card plate 28, providing good pressing capability. Pressing the lever 210 causes the card plate 28 to apply pressure to the spring 27, compressing and releasing it. After the lever 210 is activated, the spring 27 can drive the clamping plate 28 to reset. The connecting plate 24 is fixedly connected to two clamping blocks 211, which are designed to provide good clamping ability. When the connecting plate 24 and the combined plate 23 move to the outside of the support plate 1, the outside of the clamping blocks 211 can be engaged with the top of the clamping plate 28. During the engagement process, the spring 27 will be compressed, so that the adjacent combined plates 23 and the connecting plate 24 on both sides are fixed to prevent displacement during processing. The outside of the clamping blocks 211 is slidably connected to the inside of the combined plate 23. The outside of the two connecting plates 24 is on the adjacent side of the two combined plates 23, so that the connecting plate 24 and the combined plate 23 are combined to form an extended rectangle.

[0036] Reference Figure 1 , Figure 2 and Figure 6The rotating mechanism 4 includes an alignment block 41, which is designed to provide good alignment capability. The alignment block 41 is externally slidably connected to the inside of the placement groove 3. A connecting column 42 is fixedly connected to the outside of the alignment block 41, i.e., the side away from the placement groove 3, which is designed to provide good support capability. A rotating shaft 43 is fixedly connected to the outside of the connecting column 42, which is designed to provide good rotation capability. The rotation of the rotating shaft 43 can drive the connecting column 42 to rotate, causing the alignment block 41 to rotate. When the alignment block 41 slides inside the placement groove 3, the rotation of the rotating shaft 43 can drive the support plate 1 to adjust its angle. A support plate 44 is fixedly connected to the outside of the rotating shaft 43, which is designed to provide good support capability for the rotating shaft 43. The rotating shaft 43, supported by the support plate 44, can drive the connecting column 42 and the alignment block 41 to rotate. The outside of the placement groove 3 is respectively opened on the outside of the combination plate 23 and the connecting plate 24, and the outside of the placement groove 3 is opened around the support plate 1.

[0037] Working principle: When splicing is required, the combination plate 23 and connecting plate 24 are first slid into the support plate 1 via the sliding plate 22 and connecting rod 21. As the connecting rod 21 slides, the sliding plate 22 slides within the sliding groove 25, preventing displacement during further processing and ensuring a close fit with the support plate 1. Then, by pressing the actuating rod 210, the locking plate 28 moves downwards against the spring force of the spring 27, locking the locking plate 28 and the locking block 211. This secures the combination plate 23 and connecting plate 24 around the support plate 1, preventing displacement during processing. The design ensures that the combination plate 23 fits snugly against the support plate 1, and that the side of the connecting plate 24 adjacent to the combination plate 23 also fits snugly against the support plate 1, thus achieving the splicing and extension of the backlight to form a larger rectangular structure. In summary, by releasing the lever 210, the spring force of the spring 27 will cause the clamping plate 28 to return to its original position. The top of the clamping plate 28 engages with the outside of the clamping block 211, thereby fixing the adjacent combination plates 23 and connecting plates 24 together to prevent displacement during processing and to stabilize the splicing structure of the backlight.

[0038] When the angle of the backlight needs to be adjusted, press the support plate 1. The rotating shaft 43, supported by the support plate 44, begins to rotate. Since the rotating shaft 43 is fixedly connected to the connecting column 42, the rotation of the rotating shaft 43 will cause the connecting column 42 to rotate as well. Therefore, the rotation of the connecting column 42 will further drive the alignment block 41 to rotate. After sliding within the placement slot 3, the alignment block 41 rotates via the rotating shaft 43, thereby achieving angle adjustment of the backlight on the support plate 1. The design of the placement slot 3 allows the alignment block 41 to be placed stably within it, ensuring its fixation when connected to the placement slot 3. Simultaneously, the placement slot 3 is formed around the combination plate 23, the connecting plate 24, and the support plate 1. This structural design provides sufficient space for the sliding of the alignment block 41 while also ensuring the overall stability of the backlight structure. Through the rotation of the rotating shaft 43, the angle of the backlight can be flexibly adjusted according to the needs of visual inspection, thereby changing the direction of light illumination and improving the flexibility and accuracy of the inspection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
