Description

Technical Field

[0001] This utility model relates to the field of CCD camera technology, and in particular to a CCD camera mounting bracket. Background Technology

[0002] CCD cameras perform exceptionally well in low-light conditions with a high signal-to-noise ratio, making them ideal for scientific research applications that require capturing weak signals. Consequently, they are widely used in laboratory research and industrial inspection (such as appearance defect detection and dimensional measurement).

[0003] Currently, traditional CCD camera mounts are equipped with a light source mounting section in addition to the camera mounting section to improve contrast during inspection and make the features to be inspected (such as scratches, size edges, and specific organelles) more obvious. However, most of these mounts can only achieve front illumination (the light source is located above the object being measured, on the same side as the camera, with the light shining directly on the object's surface), which is used to detect minor scratches, bumps, burrs, and foreign objects on the surface of the object. But a workpiece may need to be inspected for size, characters, and multiple types of surface defects at the same time. A single light source cannot meet all the needs, especially for the inspection of transparent objects (the transparency of the object and whether there are impurities inside), where the detection effect of front illumination alone is not obvious. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a CCD camera mounting base, which, through the transparent glass plate inside the mounting platform and the light source fixing mechanism located above and below it, can simultaneously provide front and back lighting for the object being inspected, thereby expanding the angle and range of the light source illumination, increasing the scope of object inspection, and improving the inspection effect and accuracy.

[0006] To achieve the above objectives, the first aspect of this utility model provides a CCD camera mounting base, comprising: a base, a first support rod, a placement platform, two light source fixing mechanisms, and a camera fixing mechanism, wherein the first support rod is disposed on the upper part of the base; the placement platform is connected to the first support rod; the two light source fixing mechanisms are respectively connected to the first support rod and are located on the upper and lower parts of the placement platform; the camera fixing mechanism is connected to the first support rod and is located on the upper part of the light source fixing mechanisms.

[0007] In addition, the CCD camera mounting bracket proposed above according to this utility model may also have the following additional technical features: Specifically, the placement platform includes a frame, a first connecting block, a first bolt, a transparent glass plate, and a baffle. The first connecting block is connected to the rear side of the frame and is sleeved on the first support rod. The first bolt is threadedly connected to the first connecting block. The transparent glass plate is disposed inside the frame. The baffle is disposed on the upper part of the transparent glass plate.

[0008] Specifically, the light source fixing mechanism includes a second connecting block, a second bolt, a second support rod, two third connecting blocks, two third bolts, and two first mounting plates. The second connecting block is sleeved on the outside of the first support rod; the second bolt is threadedly connected to the second connecting block; the second support rod passes through the second connecting block; the two third connecting blocks are respectively sleeved on the outside of the second support rod; and the two third bolts respectively pass through the corresponding first mounting plate and are threadedly connected to the corresponding third connecting block.

[0009] Specifically, the camera fixing mechanism includes a fourth connecting block, a fourth bolt, a third support rod, a fifth connecting block, a fifth bolt, a second mounting plate, and a sixth bolt. The fourth connecting block is sleeved outside the first support rod; the fourth bolt is threadedly connected to the fourth connecting block; the third support rod passes through the fourth connecting block; the fifth connecting block is sleeved outside the third support rod; the fifth bolt is threadedly connected to the fifth connecting block; and the second mounting plate is connected to the fifth connecting block via the sixth bolt.

[0010] Specifically, a spirit level is provided on the upper part and one side of the second mounting plate.

[0011] Specifically, the upper part of the baffle is provided with two pull buttons.

[0013] 2. The CCD camera mounting base of this utility model can simultaneously illuminate the front and back of the object being tested by means of a transparent glass plate inside the placement platform and light source fixing mechanisms located above and below it, thereby expanding the angle and range of light source illumination, increasing the scope of object detection, and improving detection effect and accuracy.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes an embodiment of the CCD camera mounting bracket of this utility model with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, the CCD camera mounting base of this utility model embodiment may include: a base 1, a first support rod 2, a placement platform 3, two light source fixing mechanisms 4 and a camera fixing mechanism 5.

[0020] The first support rod 2 is located on the upper part of the base 1.

[0021] Understandably, the first support rod 2 is made of stainless steel tubing, which is high in strength, lightweight, and has good stability.

[0022] The placement platform 3 is connected to the first support rod 2.

[0023] Understandably, the placement platform 3 is used to place the item to be inspected and can be adjusted up and down along the first support rod 2.

[0024] The two light source fixing mechanisms 4 are respectively connected to the first support rod 2 and are located at the upper and lower parts of the placement platform 3.

[0025] It is understandable that the light source fixing mechanism 4 can move up and down along the first support rod 2 and adjust the illumination angle. The upper light source fixing mechanism 4 is used to fix the light source to illuminate the front of the item, and the lower light source fixing mechanism 4 is used to fix the light source to illuminate the back of the item through the placement platform 3.

[0026] The camera fixing mechanism 5 is connected to the first support rod 2 and is located above the light source fixing mechanism 4.

[0027] Understandably, the camera fixing mechanism 5 is used to install and fix the CCD camera, and can be moved up and down along the first support rod 2 for adjustment.

[0028] Specifically, when performing multi-faceted appearance inspections on items, this CCD camera mounting bracket is used to install and fix the CCD camera and light source.

[0029] The relevant personnel first installed and fixed the CCD camera on the camera fixing mechanism 5, and then installed and fixed multiple light sources on the light source fixing mechanism 4 respectively.

[0030] Then, the item is placed on the placement platform 3, the position of the item is observed through the imaging system, and the height of the placement platform 3 is adjusted in sequence as needed. The distance between the CCD camera and the item and the shooting angle of the CCD camera are adjusted through the camera fixing mechanism 5, and the distance between the light source and the item is adjusted through the light source fixing mechanism 4.

[0031] Finally, different light sources are turned on and the angle of light is adjusted according to the items to be tested. The CCD camera takes pictures of the items according to the different light illumination and transmits the images to the computer for analysis (for example, using backlit images to measure the outline, size and transparency of the items, and using front-lit images to identify surface defects of the items).

[0032] In one embodiment of this utility model, such as Figure 2 As shown, the placement platform 3 includes a frame 301, a first connecting block 302, a first bolt 303, a transparent glass plate 304, and a baffle 305.

[0033] The first connecting block 302 is connected to the rear side of the frame 301. The first connecting block 302 is sleeved on the first support rod 2. The first bolt 303 is threadedly connected to the first connecting block 302. The transparent glass plate 304 is set inside the frame 301. The baffle 305 is set on the upper part of the transparent glass plate 304.

[0034] Two pull buttons 3051 are provided on the upper part of the baffle 305.

[0035] It should be noted that the thickness of the frame 301 is greater than the thickness of the transparent glass plate 304, so that a groove is formed between the frame 301 and the transparent glass plate 304 to accommodate the baffle 305. When the equipment is not in use or the item does not need to be backlit, the baffle 305 covers the transparent glass plate 304 to protect the transparent glass plate 304 and prevent its surface from being scratched by external factors. The baffle 305 can be removed from the frame 301 by using the pull button 3051.

[0036] It is understandable that by tightening the first bolt 303, the clamping or loosening of the first connecting block 302 on the first support rod 2 can be adjusted, thereby adjusting the installation height of the frame 301.

[0037] In one embodiment of this utility model, such as Figure 3 As shown, the light source fixing mechanism 4 includes a second connecting block 401, a second bolt 402, a second support rod 403, two third connecting blocks 404, two third bolts 405, and two first mounting plates 406.

[0038] The second connecting block 401 is sleeved on the outside of the first support rod 2, the second bolt 402 is threadedly connected to the second connecting block 401, the second support rod 403 passes through the second connecting block 401, the two third connecting blocks 404 are respectively sleeved on the outside of the second support rod 403, and the two third bolts 405 respectively pass through the corresponding first mounting plate 406 and are threadedly connected to the corresponding third connecting block 404.

[0039] It should be noted that the first mounting plate 406 described in this embodiment has a strip-shaped first mounting hole in the middle for mounting the light source with screws.

[0040] Specifically, during the testing, multiple strip light sources are installed on the side of the first mounting plate 406 near the frame 301. Then, as needed, the second bolt 402 is rotated to adjust the distance between the light source and the object through the second connecting block 401. The third bolt 405 is rotated to adjust the distance between the two horizontal light sources through the third connecting block 404. The illumination angle of the light source is adjusted through the first mounting plate 406.

[0041] The upper light source can illuminate the object from the front to detect surface defects (such as scratches, dents, etc.). When it is necessary to detect the size and outline of the object, the baffle 305 can be removed by pulling the button 3051, and the object can be placed on the transparent glass plate 304. The lower light source forms a uniform surface light source through the transparent glass plate 304, showing the outline shadow. Thus, the CCD camera can take a high-contrast black and white silhouette image to accurately measure the size and outline of the object. When detecting transparent objects such as glass and plastic, the light source passes through the transparent object to detect its transparency or whether there are impurities inside.

[0042] As a possible alternative, a ring light source can also be installed between the two first mounting plates 406 to adapt to different detection lighting scenarios.

[0043] In one embodiment of this utility model, such as Figure 4 As shown, the camera fixing mechanism 5 includes a fourth connecting block 501, a fourth bolt 502, a third support rod 503, a fifth connecting block 504, a fifth bolt 505, a second mounting plate 506, and a sixth bolt 507.

[0044] The fourth connecting block 501 is sleeved on the outside of the first support rod 2, the fourth bolt 502 is threadedly connected to the fourth connecting block 501, the third support rod 503 passes through the fourth connecting block 501, the fifth connecting block 504 is sleeved on the outside of the third support rod 503, the fifth bolt 505 is threadedly connected to the fifth connecting block 504, and the second mounting plate 506 is connected to the fifth connecting block 504 by the sixth bolt 507.

[0045] It should be noted that the second mounting plate 506 described in this embodiment has multiple second mounting holes, which can be adapted to CCD cameras of different models and specifications.

[0046] Specifically, during testing, the CCD camera is mounted on the second mounting plate 506. The fourth bolt 502 is rotated, and the distance between the CCD camera and the object is adjusted as needed via the fourth connecting block 501. The fifth bolt 505 is rotated, and the position of the CCD camera on the third support rod 503 is adjusted via the fifth connecting block 504, so that the camera can be accurately aligned with the object. The second mounting plate 506 can be loosened or clamped by rotating the sixth bolt 507, thereby adjusting the shooting angle of the CCD camera by rotating the second mounting plate 506.

[0047] In one embodiment of this utility model, such as Figure 4 As shown, a spirit level 5061 is provided on the upper part and one side of the second mounting plate 506.

[0048] Understandably, when the CCD camera needs to be kept at a horizontal angle for shooting, the relevant personnel can adjust the angle of the second mounting plate 506 by observing the bubble level 5061 to keep the camera horizontal.

[0049] In summary, the CCD camera mounting base of this utility model, through the transparent glass plate inside the placement platform and the light source fixing mechanism located above and below it, can simultaneously provide front and back lighting for the object being inspected, thereby expanding the angle and range of the light source illumination, increasing the scope of object inspection, and improving the inspection effect and accuracy.
