Description

Technical Field

[0001] This utility model relates to the field of detection of a combination of spherical integral and side shadowless light source, and particularly to a detection device for a combination of spherical integral and side shadowless light source. Background Technology

[0002] A sphere integrating light source is a special type of lighting source. Its working principle involves placing multiple light sources inside a closed sphere, causing light to undergo multiple reflections and scatterings within the sphere before exiting uniformly from its surface. This design achieves highly uniform illumination, reducing shadows and light spots. Key features include: Uniform illumination (providing highly uniform lighting, suitable for applications requiring high uniformity, such as optical inspection and photography); Multi-angle illumination (allowing for observation of different sides of objects due to light emanating from the sphere's surface); High stability (the relatively stable structure of the sphere integrating light source makes it less susceptible to external interference, providing stable light output); and Adjustability (some sphere integrating light sources allow for adjustment of light intensity and color temperature to meet diverse application needs).

[0003] During the production process, it is often necessary to inspect products for defects such as cracks. Traditional inspection methods involve manual operation using optical systems such as magnifying glasses and microscopes. This method is extremely inefficient, labor-intensive, and prone to errors. To address this, we propose a combined inspection device using a spherical integral light source and a side shadowless light source. Utility Model Content

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

[0005] A combined detection device for spherical integral and side shadowless light source includes a base, a fixed frame fixedly connected to the top of the base, the fixed frame being n-shaped, a lifting component being provided inside the fixed frame, a motor being provided at the top of the fixed frame, a transmission component being provided at the output end of the motor, a movable plate being provided inside the fixed frame, a support component being provided at the top of the movable plate, and a detection component being provided at the bottom of the movable plate.

[0006] Furthermore, a support frame is fixedly connected to the top of the fixed frame, and the motor is fixedly mounted on the support frame. The support frame ensures that the motor will not idle during operation.

[0007] Furthermore, the lifting assembly includes a threaded sleeve rotatably connected to the top of the fixed frame, the threaded sleeve extending into the interior of the fixed frame, and a threaded rod threadedly connected to the interior of the threaded sleeve. The bottom of the threaded rod is located at the top of the movable plate. The height of the CCD camera can be adjusted by the lifting assembly.

[0008] Furthermore, the transmission assembly includes a rotating shaft fixedly connected to the output end of the motor, a first gear fixedly sleeved on the outside of the rotating shaft, and a second gear fixedly sleeved on the outside of the threaded sleeve. The first gear and the second gear are meshed and connected, and the threaded sleeve can be rotated through the transmission assembly.

[0009] Furthermore, the support assembly includes a telescopic sleeve fixedly connected to the top of the fixed frame, the telescopic sleeve extending into the interior of the fixed frame, and a telescopic rod slidably connected inside the telescopic sleeve. The bottom of the telescopic rod is fixedly connected to the top of the movable plate. By setting the support assembly, the movable plate can be made more stable when moving.

[0010] Furthermore, the detection component includes a CCD camera fixedly installed at the bottom of the movable plate, and a light-emitting block fixedly installed at the top of the base. The internal components of the product can be detected through the detection component.

[0011] Furthermore, a spherical integrating light source is provided on the outside of the light-emitting block, and a side shadowless light source plate is provided on the top of the spherical integrating light source. The spherical integrating light source and the side shadowless light source plate can provide light to the product being tested.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When a product needs to be tested, the product is first placed on the outside of the light-emitting block. The top of the material to be tested and the side to be tested are extended into the sphere integrating light source and the side shadowless light source plate. Then, the CCD camera is moved to the top of the sphere integrating light source. At this time, the CCD camera can test the product. The operating platform of this application is Windows 7X64 with an image acquisition card. The CCD camera model is MER-503-20GM500w black and white global shutter camera. The CCD camera lens model is HL-WT-OUT-D1371 0 million 2 / 3 external 360 side wall lens. The light source model is HL-SPQ11552-W sphere integrating light source and side shadowless light plate.

[0014] 2. This utility model starts the motor, at which point the output end of the motor drives the rotating shaft and the first gear to rotate. Since the first gear and the second gear are meshed, the rotation of the first gear drives the rotation of the second gear, which in turn drives the threaded sleeve to rotate. At this time, the threaded rod, the moving plate, and the CCD camera begin to move, and the height of the CCD camera can be adjusted.

[0015] 3. With the above-mentioned structure, this utility model can inspect products and detect whether there are defects in the internal bends and arcs of the product. The inspection effect is better. At the same time, the height of the CCD camera can be adjusted to adapt to products of different heights. It has strong adaptability and greatly facilitates the use of staff. Attached Figure Description

A first gear 10 is fixedly sleeved on the outside of the rotating shaft 9, and a second gear 12 is fixedly sleeved on the outside of the threaded sleeve 11. The first gear 10 and the second gear 12 are meshed together. Through the transmission assembly, the threaded sleeve 11 can be rotated. A movable plate 14 is provided inside the fixed frame 2, and a support assembly is provided on the top of the movable plate 14. The support assembly includes a telescopic sleeve 15 fixedly connected to the top of the fixed frame 2.
