Description

Technical Field

[0001] This application relates to the field of machine tool light sources, and in particular to a Rubik's Cube light source device. Background Technology

[0002] Automated Optical Inspection (AOI) is a widely used inspection technology in industrial production. It is a technique based on optical principles to detect defects. A camera automatically scans the material to be inspected (such as a PCB board), acquires images, and then processes the images to detect defects on the material.

[0003] In related technologies, the camera device's position on the inspection platform is relatively fixed. Even if the lens module can undergo minor posture adjustments, the camera scanning process suffers from uneven light distribution due to limitations imposed by the size of the equipment and the material being inspected. For example, obstructions from parts can cause uneven light distribution, and changes in light intensity can occur due to displacement during line scanning. These factors all affect the image quality of the line scan and subsequent visual inspection. Some equipment typically installs auxiliary light source components, but these components have poor adjustability. Furthermore, the required number of light source components varies depending on the material, and disassembly can severely impact inspection efficiency. Summary of the Invention

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0035] In this article, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0036] like Figure 1 The diagram shown is a structural schematic of the Rubik's Cube light source device provided in this embodiment of the application. The Rubik's Cube light source device includes a light source bracket 10, several sets of light source adjustment seats 30, and a matching light source module 40. The light source module 40 is mainly a linear light source, and both ends need to be fixed, so it is fixed by pairs of light source adjustment seats 30.

[0037] The light source bracket 10 includes a top plate 11 and two supporting side plates 12. A camera through-hole 111 is provided on the top plate 11, and the camera module 20 is located above the top plate 11, with the camera aperture pointing downwards to capture images of the material board. Because the camera needs to be adjustable in height, the camera through-hole 111 is provided on the top plate 11 for adaptive adjustment. The supporting side plates 12 are symmetrically arranged, and a top plate adjustment hole 112 is provided on the top plate 11, corresponding to the two side plates 12. This top plate adjustment hole 112 can be a linear hole or an oblong hole, used for small-range adjustment of the positional relationship between the top plate 11 and the side plates 12. The two side plates 12 are symmetrically arranged, and several vertically distributed mounting holes 121 are provided on their surfaces. The top plate 11 is fixedly mounted above the supporting side plates 12. Optionally, to improve the stability of the bracket, a transverse support rod 13 can be provided between the symmetrically arranged supporting side plates 12 to reinforce the stability of the two side plates.

[0038] Light source adjustment seats 30 are arranged in pairs on the support side plates 12 on both sides. In actual installation, single or multiple sets are set according to requirements. In practical applications, at least one light source module 40 needs to be set on both sides of each support side plate 12, and the light source adjustment seat 30 is perpendicular to the support side plate 12. The light source adjustment seat 30 is composed of two parallel plates, namely the mounting adjustment plate 31. Linear adjustment holes 32 are provided on the mounting adjustment plate 31. The linear adjustment holes 32 match the mounting holes 121, and the mounting adjustment plate 31 is installed on the support side plate 12 by bolts, nuts and other fastening structures. Because the mounting holes 121 are vertically distributed, the height of the light source adjustment seat 30 can be adjusted up and down as needed. The mounting adjustment plate 31 is also provided with a light source adjustment assembly 33, which is used to connect the light source module 40. The light source module 40 is installed between the paired light source adjustment seats 30, and the position of the light source is adjusted by the stacked light source adjustment assembly 33.

[0039] See Figure 1 and Figure 2 A vertically oriented mounting groove 122 is provided on the supporting side plate 12. A sliding component 14 is installed in the mounting groove 122, and the mounting adjustment plate 31 is slidably mounted on the sliding component 14. Since the linear adjustment hole 32 and the mounting hole 121 can be adjusted vertically, disassembly and assembly are time-consuming and laborious when frequently adjusting the height. Therefore, the sliding component 14 provides auxiliary support. For example, by placing the mounting adjustment plate 31 on the sliding component 14, the height of the light source adjustment seat 30 can be adjusted via the sliding component after loosening the screws and nuts, achieving a time-saving and labor-saving effect. Specifically, to precisely control the height of the light source adjustment seat 30, a scale plate 15 can be installed at the mounting groove 122. The scale plate 15 records the height value for height setting. Furthermore, the scale plate 15 is installed on the mounting groove 122, and the sliding component 14 is located within the mounting groove 122 between the supporting side plate 12 and the scale plate 15. That is, the scale plate 15 covers the mounting groove 121 and the sliding component 14 within the groove, achieving both height setting and aesthetic appeal.

[0040] In one possible implementation, the sliding assembly 14 may include several open-type couplings 141 fixed in the mounting slot 122, and shafts 142 fixed by the couplings 141. This application uses the example of supporting the side plate 12 to install two sets of light source modules 40 as an example. The side plate can then symmetrically accommodate up to four light source modules and their corresponding light source adjustment seats 30. The shafts 142 correspond one-to-one with the light source adjustment seats 30, so two shafts 142 can be installed vertically, and two shafts can be symmetrically installed horizontally. Most commonly, three open-type couplings 141 can be vertically installed on the side plate, with both ends of the shafts 142 inserted into the open-type couplings 141. The difference between open-type couplings and ordinary couplings is the presence of slots, which facilitates shaft installation without removing the couplings from the side plate, thus improving installation efficiency. For example, when adding or removing light source components, the screws and nuts on the mounting adjustment plate 31 can be removed, and the connecting shaft can be directly removed from the open coupling, eliminating the hassle of disassembly and assembly. This is especially useful in scenarios where left and right ring light sources need to be adjusted; for instance, if the left light source module is disassembled and installed on the right, at least two coupling disassembly and assembly processes can be avoided. Furthermore, when adjusting the height, the shaft can be directly slid-controlled, and the adjustment accuracy is greatly improved with the help of the scale plate.

[0041] In summary, this structure uses adjustment discs to install the light source module at both ends, which can realize the adjustment of the light source angle. The adjustment discs are connected by adjustment seats and adjustment rods to realize the horizontal displacement of the light source. Multiple open couplings and matching shafts are set on the support side plate, which can facilitate the left and right switching and lifting of the light source adjustment seat, and the light source module can be freely added or removed to achieve more uniform light control.

[0042] Figure 3 The detailed structure of the mounting adjustment plate is shown. The mounting adjustment plate 31 has a protruding bushing 34 at one end near the support side plate 12. The bushing 34 is fitted onto the shaft 142 and can slide up and down along the shaft 142. When the light source modules 40 are installed at the same horizontal height on the left and right sides of the support side plate 12, a maximum of two parallel shafts 142 are required. When not needed, only one shaft needs to be installed.

[0043] See Figure 3 and Figure 4 A horizontal adjustment hole 35 is provided on the mounting adjustment plate 31, and the light source adjustment component 33 is disposed within the horizontal adjustment hole 35, allowing it to move horizontally. Both ends of the light source module 40 are fixed to the light source adjustment component 33, generating horizontal displacement through the horizontal adjustment hole 35. Furthermore, a horizontal fixing hole 36 parallel to the horizontal adjustment hole 35 is also provided on the mounting adjustment plate 31. The light source adjustment component 33 can be securely fastened within the horizontal adjustment hole 35 through the horizontal fixing hole 36, and tightened after adjustment to prevent displacement due to vibration.

[0044] See Figure 4 and Figure 5 The light source adjustment assembly 33 includes an adjustment disc 331, an adjustment base 332, and a displacement adjustment rod 333. The displacement adjustment rod 333 is horizontally positioned in a horizontal adjustment hole 35, and can be configured with two sets, upper and lower, for enhanced fixation. The adjustment base 332 is fitted onto the displacement adjustment rod 333 and slidably connected, allowing for horizontal sliding displacement of the adjustment base 332. A rotary adjustment hole 335 is provided on the adjustment base 332, into which the adjustment disc 331 is inserted and rotatably connected. Several mounting holes can be provided at the bottom of the adjustment disc 331 to fix the two ends of the light source module 40 onto the adjustment disc. When the two ends of the light source module 40 and the symmetrically arranged adjustment disc 331 are connected by fasteners, the adjustment disc 331 can be manually rotated to rotate the light source module 40, achieving angle adjustment. Furthermore, because the adjustment disc 331 is inserted into the rotary adjustment hole 335 on the adjustment base 332, the horizontal displacement of the light source module 40 can be achieved by directly moving the adjustment base 332.

[0045] Furthermore, a horizontal displacement scale can be set on the mounting adjustment plate 31, and a pointer 334 can be set on the adjustment seat 332. When the adjustment seat 332 is moved horizontally, the displacement value can be referenced by the pointer 334 and the horizontal displacement scale. An angle scale around the rotary adjustment hole 335 can be set on the adjustment seat 332, and the rotation angle can be determined when the adjustment disc 331 is rotated.

[0046] See Figure 2 and Figure 5 Considering that the outer scale plate 15 of the mounting groove 122 can perfectly cover the sliding component 14, the adjusting plate 31 can be further optimized. Specifically, the mounting groove 122 is opened at the center of the supporting side plate 12, forming flanges 123 on both sides, with vertically distributed mounting holes 121 located on the flanges 123. In addition, a vertical sliding groove 37 that cooperates with the flanges 123 is also opened on the mounting adjusting plate 31 near the supporting side plate 12, and the vertical sliding groove 37 is interconnected with the linear adjusting hole 32. In this way, when the adjusting plate 31 is fitted onto the shaft 142, the vertical sliding groove 37 can engage with the flanges 123, preventing the shaft from extending outside the mounting groove 122.

[0047] See Figure 6 and Figure 7 When the size of the light source module structure is suitable, it can be fixed by simply using the adjustment plate 331. However, for the coaxial light source module, the volume is relatively larger and it is set horizontally. Therefore, it is necessary to add a connecting plate 336 on the basis of the adjustment plate 331. The size of the connecting plate 336 is larger than that of the adjustment plate 331, and it is installed between the adjustment plate 331 and the coaxial light source module. At the same time, more fixing holes are opened on the adjustment plate 331 to achieve a better installation effect.

[0048] In summary, this application features mounting slots and multiple sets of mounting holes on the support side plate to accommodate the sliding assembly, covered by a scale plate. The mounting adjustment plate, forming the light source adjustment seat, can be fitted onto the sliding assembly, enabling up-and-down sliding adjustment based on the shaft and coupling. On the mounting adjustment plate, the horizontal and angular adjustments of the light source module can be achieved using an adjustment disc, adjustment seat, and displacement adjustment rod, thus realizing multi-angle adjustment of the light source. In particular, the open-type coupling and shaft design allows for quick replacement of the light source adjustment seat, improving equipment assembly and disassembly efficiency while also expanding its application scenarios.
