[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a CCD quality inspection device, including a frame 1. A first conveyor belt 2, a second conveyor belt 3, and a third conveyor belt 4 are installed sequentially from top to bottom on one side of the frame 1. A first CCD 5 is arranged above the first conveyor belt 2, a second CCD 6 is arranged above the second conveyor belt 3, and a third CCD 7 is arranged above the third conveyor belt 4. A hopper 8 is installed on one side of the frame 1, with the bottom of the hopper 8 corresponding to the first conveyor belt 2. A first transfer belt 11 is arranged at the bottom right of the first conveyor belt 2, with the bottom end of the first transfer belt 11 facing the top end of the second conveyor belt 3. A second transfer belt 12 is arranged at the bottom left of the second conveyor belt 3, with the bottom end of the second transfer belt 12 facing the top end of the third conveyor belt 4. Defective product collection boxes 15 are arranged opposite each other on one side of the first transfer belt 11 and the second transfer belt 12. A product collection box 16 is arranged at the bottom right of the third conveyor belt 4.

[0026] Among them, baffles 14 are installed on both sides of the first conveyor belt 2, the second conveyor belt 3 and the third conveyor belt 4. A connecting rod 9 is installed at the bottom of the right baffle 14. A cleaning roller 10 is rotatably installed at one end of the connecting rod 9. The surfaces of multiple sets of cleaning rollers 10 are in contact with the surfaces of the corresponding conveyor belts. The baffles 14 can prevent objects from falling or deviating from the track during the conveying process and ensure the stability of the conveying. The cleaning rollers 10 can clean the debris and debris on the surface of the conveyor belt in a timely manner, keep the conveyor belt clean, and avoid interference with product inspection.

[0027] The first conveyor belt 11 and the second conveyor belt 12 are both fixedly connected to one side of the frame 1 by a bracket. Multiple sets of placement blocks 13 are installed at equal intervals on the outer walls of the first conveyor belt 11 and the second conveyor belt 12. The top of each set of placement blocks 13 is provided with a placement groove. By setting the placement groove, the product can be better restricted and prevented from moving or falling during the transfer process.

[0028] In this configuration, a first pulley 142 is rotatably mounted at one end of the first conveyor belt 2 and the second transfer belt 12, and a first belt 141 is connected between the two sets of first pulleys 142. A third pulley 161 is rotatably mounted at one end of the second transfer belt 12 and the third conveyor belt 4, and a third belt 162 is connected between the two sets of third pulleys 161. A second pulley 151 is rotatably mounted at one end of the first transfer belt 11 and the second conveyor belt 3, and a second belt 152 is connected between the two sets of second pulleys 151.

[0029] The hopper 8 is equipped with a solenoid valve at the bottom outlet, and the cleaning roller 10 is covered with cleaning materials such as brush bristles or sponges. The solenoid valve at the bottom outlet of the hopper 8 can control the falling of the product, which facilitates automated control. The cleaning material on the surface of the cleaning roller 10 can effectively clean the debris and debris on the surface of the conveyor belt, further improving the accuracy of detection.

[0030] The first conveyor belt 2, the second conveyor belt 3, the third conveyor belt 4, the first CCD 5, the second CCD 6, the third CCD 7, the first transfer belt 11, the second transfer belt 12, and the solenoid valve are all electrically connected to an external control system. The first CCD 5 enables preliminary product inspection, promptly identifying products with potential defects, thus improving the efficiency of subsequent inspections and avoiding wasted time and resources. The second CCD 6 allows for more in-depth inspection of minor surface defects, scratches, stains, and other issues, further improving the precision and accuracy of the inspection and more effectively ensuring product quality. The third CCD 7 provides final quality confirmation, ensuring the product meets quality standards and preventing defective products from entering the market. It can also detect issues that might be overlooked in the first two inspections, further enhancing product reliability.

[0031] The defective product collection box 15 is equipped with a connecting frame 17 on one side. A T-shaped slider is provided at one end of the connecting frame 17. The frame 1 has a matching T-shaped groove at the position opposite to the T-shaped slider. The T-shaped slider is slidably connected to the T-shaped slider, and the product collection box 16 is placed on the frame 1.

[0032] The working principle of this embodiment is as follows: First, the product to be tested is placed into the hopper 8. The solenoid valve at the bottom outlet of the hopper 8 is controlled by an external control system to make the product fall onto the first conveyor belt 2 in an orderly manner.

[0033] On the first conveyor belt 2, the baffles 14 on both sides ensure that the product will not fall or deviate from the track during the conveying process, thus ensuring the stability of the conveying. At this time, the first CCD 5 performs a preliminary inspection of the product. When a defective product is detected, the external control system will control the solenoid valve to close, stopping the product from falling further. At the same time, the defective product will be conveyed to the bottom right end of the first conveyor belt 2 and fall onto the placement block 13 on the first transfer belt 11. When the defective product falls onto the placement block 13, the first transfer belt 11 will reverse and convey the defective product into the corresponding defective product collection box 15.

[0034] After the product is transferred to the second conveyor belt 3, the baffle 14 and the cleaning roller 10 begin to function. The cleaning material on the surface of the cleaning roller 10 will clean the debris and shavings on the surface of the conveyor belt in a timely manner, keeping the conveyor belt clean and avoiding interference with product detection. At the same time, the second CCD 6 detects the product. When a defective product is detected, similar to the operation when the first CCD 5 detects a defective product, the external control system will control the relevant components to perform corresponding actions. Specifically, the solenoid valve closes, stopping the subsequent products from falling. The defective product falls onto the placement block 13 on the second conveyor belt 12. Then the second conveyor belt 12 reverses, transporting the defective product to the corresponding defective product collection box 15.

[0035] Next, the product enters the second transfer belt 12 through the bottom left end of the second conveyor belt 3 and is transferred to the third conveyor belt 4. On the third conveyor belt 4, the third CCD 7 performs a final quality check on the product to ensure that the product meets the quality standards.

[0036] Finally, based on the test results, defective products will be pushed into the defective product collection box 15 on one side of the first conveyor belt 11 and the second conveyor belt 12, while qualified products will enter the product collection box 16 at the bottom right of the third conveyor belt 4.

[0037] Throughout the entire operation, the power transmission between each conveyor belt and the transfer belt is achieved through the connection of pulleys and belts. Furthermore, the first conveyor belt 2, the second conveyor belt 3, the third conveyor belt 4, the first CCD 5, the second CCD 6, the third CCD 7, the first transfer belt 11, the second transfer belt 12, and the solenoid valve are all electrically connected to an external control system. The operation of the entire equipment is controlled and monitored by the external control system.

[0038] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
