Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an automated CCD inspection device, including an inspection stage 6. An X-axis moving module 2 is fixedly mounted on the upper surface of the inspection stage 6. A Y-axis moving module 3 is fixedly connected to the X-axis moving part 201 of the X-axis moving module 2. A mounting plate 4 is fixedly connected to the bottom end of the Y-axis moving part 301 of the Y-axis moving module 3. An inspection camera 5 is detachably connected to the bottom surface of the mounting plate 4. A dust removal component 1 is also provided on the mounting plate 4, and the dust removal component 1 includes an L-shaped connecting plate 101. A U-shaped mounting bracket 104 is slidably connected to one side of the L-shaped connecting plate 101. A brush roller 105 is rotatably connected between the inner walls of both sides of the U-shaped mounting bracket 104. A first dust suction hood 107 is provided on one side of the brush roller 105. The first dust suction hood 107 is connected to the exhaust end of the fan 109 through the first dust suction pipe 108. The fan 109 is fixedly installed on the upper surface of the dust collection box 110. The dust collection box 110 is fixedly installed on the upper surface of the mounting plate 4. The exhaust end of the fan 109 is connected to the inside of the dust collection box 110.

[0022] Please see Figure 3 and Figure 4The L-shaped connecting plate 101 is fixedly connected to one side surface of the mounting plate 4. A slide rail 102 is fixedly installed on one side surface of the L-shaped connecting plate 101. One end of the connecting rod 103 is slidably installed on the slide rail 102. The other end of the connecting rod 103 is fixedly connected to the upper surface of the U-shaped mounting bracket 104. A cylinder 116 is fixedly installed on one side surface of the L-shaped connecting plate 101. One end of the piston rod of the cylinder 116 is fixedly connected to one side surface of the connecting rod 103. A drive motor 106 is fixedly installed on one end surface of the U-shaped mounting bracket 104. One end of the output shaft of the drive motor 106 is fixedly connected to one end of the brush roller 105 through a through hole opened on one end surface of the U-shaped mounting bracket 104.

[0023] When the mounting plate 4 and the detection camera 5 move independently relative to the detection stage 6 along the X-axis moving module 2 and the Y-axis moving module 3, the position of the brush roller 105 also moves synchronously. At the same time, driven by the cylinder 116, the connecting rod 103 can drive the U-shaped mounting frame 104 and the brush roller 105 to adjust their height along the Z-axis, so that the brush roller 105 is close to the item to be detected. The drive motor 106 drives the brush roller 105 to rotate inside the U-shaped mounting frame 104 to actively clean the dust accumulated on the surface of the item to be detected. The dust that falls off is sucked into the first dust suction hood 107 by the airflow generated by the fan 109 and transported to the air outlet of the fan 109 through the first dust suction pipe 108 and collected in the dust collection box 110. After cleaning the dust on the surface of the item to be detected, the cylinder 116 drives the U-shaped mounting frame 104 and the brush roller 105 to rise and reset to avoid affecting the imaging effect of the detection camera 5. Actively removing the dust from the surface of the item to be detected can ensure the accuracy of CCD automatic detection.

[0024] Furthermore, a three-way connector 112 is connected to the exhaust end of the fan 109, and is connected to one end of the first suction pipe 108 through the three-way connector 112. One end of the second suction pipe 113 is connected to the other end of the three-way connector 112, and the other end of the second suction pipe 113 is connected to the second suction hood 114. The second suction hood 114 is located on the bottom surface of the mounting plate 4 on the side of the detection camera 5, and is movably connected to the U-shaped mounting bracket 104.

[0025] The blower 109 is simultaneously connected to the second dust hood 114 via the three-way connector 112 and the second suction pipe 113. The second dust hood 114 is movably connected to the bottom surface of the mounting plate 4 on one side of the detection camera 5. This can further reduce the dust that is stirred up when cleaning the surface of the item to be tested, which adheres to the lens of the detection camera 5 and affects the imaging, thereby improving and reducing the impact of dust on the detection accuracy during the cleaning process.

[0026] Furthermore, the height of the second dust hood 114 is higher than the bottom of the detection camera 5.

[0027] The height of the second dust cover 114 is higher than the lens height of the detection camera 5, so as to avoid obstruction when the detection camera 5 is taking pictures of the object to be tested, and improve the practicality during use.

[0028] Furthermore, the first dust hood 107 and the second dust hood 114 are movably connected to one side surface of the U-shaped mounting bracket 104 and the bottom surface of the mounting plate 4 via the first connecting bracket group 111 and the second connecting bracket group 115, respectively. The first connecting bracket group 111 and the second connecting bracket group 115 each include two oppositely arranged connecting brackets. One end of a damping shaft is rotatably connected to one side surface of each of the two connecting brackets. The first dust hood 107 and the second dust hood 114 are respectively fixedly connected between the corresponding two damping shafts.

[0029] The first dust hood 107 and the second dust hood 114 are rotatably connected to the U-shaped mounting bracket 104 and the mounting plate 4 through the first connecting bracket group 111 and the second connecting bracket group 115, respectively. Both are connected by a damping shaft. During use, the angles of the first dust hood 107 and the second dust hood 114 can be adjusted according to the specific testing conditions, and the damping shaft is used for stable positioning, thereby reducing the limitations during use.

[0030] Furthermore, there are two sets of dust removal components 1, which are symmetrically arranged with the center point of the mounting plate 4 as the axis.

[0031] By setting dust removal components 1 on both sides of the mounting plate 4, the efficiency of dust removal on the surface of the test item can be further improved. When the mounting plate 4 moves with the X-axis moving module 2 and the Y-axis moving module 3, the positions of the two dust removal components 1 are synchronously displaced, which can achieve a large-scale coverage of the surface of the test table 6. No matter how the test item is placed, the efficiency of dust removal is achieved through the coordinated driving of the X-axis moving module 2 and the Y-axis moving module 3 and the large-scale coverage of the two dust removal components 1.

[0032] Furthermore, a dust removal operation door is provided on one side surface of the dust collection box 110.

[0033] After the two sets of dust removal components 1 perform dust removal and suction, the dust is collected in the dust collection box 110. The dust inside can be cleaned out through the dust removal operation door (not shown in the figure), improving the convenience of use. At the same time, the surface of the dust collection box 110 has an air outlet, and a filter screen is installed at the air outlet. The air carrying dust enters the dust collection box 110 and is then discharged from the air outlet. The filter screen filters out the dust and collects it inside the dust collection box 110.

[0034] Working principle: The new energy vehicle battery box is placed on the surface of the testing platform 6. The X-axis moving module 2 and the Y-axis moving module 3 work together to drive the mounting plate 4 and the testing camera 5 to perform dual-axis planar displacement above the testing platform 6. Before testing, the two sets of symmetrically distributed dust removal components 1 move synchronously. The cylinder 116 drives the U-shaped mounting bracket 104 and the brush roller 105 to adjust the Z-axis height, so that the brush roller 105 is close to the surface of the object to be tested. The drive motor 106 drives the brush roller 105 to rotate and sweep away the accumulated dust. The fan 109 provides negative pressure to the first dust suction hood 107 and the second dust suction hood 114 synchronously through the three-way connector 112. The first and second dust collection hoods collect the dust raised by the sweeping and transport it to the dust collection box 110. The second dust collection hood forms an airflow barrier on the side of the detection camera 5 to prevent dust from contaminating the lens. The first and second dust collection hoods are connected by a damping pivot shaft to adjust the angle of the first and second connecting frame group to improve dust collection efficiency. The two dust collection components work together to move along the XY axis to achieve full coverage of the detection area. During detection, the cylinder 116 retracts to raise the brush roller 105 to avoid obstructing the camera imaging. After the dust is collected in the dust collection box 110, it can be cleaned through the side dust cleaning operation door, which improves the dust cleaning efficiency, reduces the probability of lens contamination, and improves the CCD detection accuracy of components such as new energy vehicle battery boxes.

[0035] It should be noted that the specific models and specifications of the X-axis moving module 2, Y-axis moving module 3, detection camera 5 drive motor 106, fan 109 and cylinder 116 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and operating principles of the X-axis moving module 2, Y-axis moving module 3, detection camera 5 drive motor 106, fan 109 and cylinder 116 are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
