Description

Technical Field

[0002] The PCB manufacturing process involves several key steps, including substrate preparation, pattern transfer, etching, drilling, electroplating, solder mask printing, surface treatment, and shape processing. Among these, the substrate, as the core carrier of the PCB, plays a decisive role in the stability of subsequent processing steps and the quality of the final product.

[0003] During the PCB substrate shaping stage, mechanical processing methods such as cutting and rounding are required to ensure the substrate meets different specifications. However, in actual processing, PCB substrates are affected by various factors such as equipment precision limitations, material defects, and process fluctuations. Some substrates may have defects such as dimensional deviations, edge damage, or surface defects. If these defective products are not detected and rejected in time, but continue to enter subsequent processing stages (such as drilling and electroplating), it will not only affect the overall quality of the PCB board, but also cause unnecessary waste of processing materials, thereby increasing production costs. Therefore, after the substrate processing is completed, quality sorting of the PCB board is required to effectively remove defective products. Utility Model Content

The substrate outline processing stage is located on the left side of the processing table 1, and the pattern transfer stage is located on the right side of the processing table 1; a gripping component 2 located on the right side of the processing table 1, which is used to grip and transfer the PCB substrate. It consists of an electric rail, a cylinder, and a suction cup assembly. The suction cup assembly picks up and puts down the PCB substrate, the cylinder controls the suction cup assembly to move up and down, and the electric rail controls the suction cup assembly to move left and right; a conveying component 3 located on the left side of the processing table 1, which consists of a roller and a motor. The motor drives the roller to rotate and transport the PCB substrate to the left; and a smart control cabinet 4 fixedly installed on the front side of the processing table 1. The gripping component 2 and the conveying component 3 are electrically connected to the smart control cabinet 4 and are uniformly coordinated and controlled by the smart control cabinet 4.

[0018] Combination Figures 1-3 As shown, the device also includes: a first mounting platform 5 fixedly installed on the right side of the processing table 1, the first mounting platform 5 being positioned below the gripping component 2, and the gripping component 2 passing over the first mounting platform 5 when transferring the PCB substrate; a first vision camera 6 fixedly installed on the upper side of the first mounting platform 5, the first vision camera 6 being electrically connected to the intelligent control cabinet 4, the first vision camera 6 being used to acquire the appearance image of the lower surface of the PCB substrate and transmit the data to the intelligent control cabinet 4, where the intelligent control cabinet 4 performs feature extraction and analysis; an electric push rod 7 fixedly installed on the left side of the processing table 1; and a baffle 8 slidably installed on the left side of the processing table 1, the baffle 8 being located on the far left of the conveying component 3, used to restrict the PCB substrate being transported by the conveying component 3, the baffle 8 being connected to the electric push rod 7. The control terminal is fixed, and the baffle 8 moves vertically. A second mounting platform 9 is fixedly installed on the left side of the processing table 1. The first mounting platform 5 is set above the conveying component 3. When the conveying component 3 transfers the PCB substrate, it will pass under the second mounting platform 9. A second vision camera 10 is fixedly installed on the lower side of the second mounting platform 9. The second vision camera 10 is electrically connected to the intelligent control cabinet 4. The second vision camera 10 is used to acquire the appearance image of the upper surface of the PCB substrate and transmit the data to the intelligent control cabinet 4 for feature extraction and analysis. A discharge component is set on the processing table 1. The discharge component is electrically connected to the intelligent control cabinet 4. The discharge component is used to remove the unqualified PCB substrates from the processing table 1 according to the comparison and analysis results of the intelligent control cabinet 4.

[0019] Combination Figure 1 and Figure 3As shown, the discharge assembly includes: a mounting base plate 11 fixedly mounted on the processing table 1, the mounting base plate 11 being positioned below the rollers of the conveying assembly 3; an electric slide rail 12 fixedly mounted on the mounting base plate 11, the electric slide rail 12 being arranged in a front-to-back direction, and an opening for the PCB substrate to pass through being provided at the processing table 1 on the front side of the electric slide rail 12; a pusher 13 slidably mounted on the mounting base plate 11, the pusher 13 being fixed to the control end of the electric slide rail 12, the pusher 13 moving back and forth, and the pusher 13 passing between the rollers; and a collection rack 14 fixedly mounted on the front side of the processing table 1, the collection rack 14 being located at the opening of the processing table 1.

[0020] After the PCB substrate completes its shape processing, it is conveyed to the gripping station below the gripping component 2. The gripping component 2 controls the suction cup assembly on it to move down and until it contacts the PCB substrate. Then, it controls the suction cup assembly to stably adhere the PCB substrate. After completion, the gripping component 2 moves the PCB substrate upward and controls the PCB substrate to move left to the inspection station of the first vision camera 6. The first vision camera 6 will capture an image of the appearance of the lower surface of the PCB substrate and transmit the image data to the intelligent control cabinet 4 for feature extraction and analysis. Afterward, the gripping component 2 moves the PCB substrate above the conveying component 3, moves it down and releases it to transfer it onto the conveying component 3. The conveying component 3 then moves the PCB substrate to the left to the inspection station of the second vision camera 10. In the first stage, the second vision camera 10 captures an image of the surface of the PCB substrate and sends the data to the intelligent control cabinet 4 for feature extraction and analysis. Finally, the intelligent control cabinet 4 compares the input data with preset qualified data to determine the quality of each PCB. When non-conforming features such as dimensional deviation or surface defects are detected, the electric push rod 7 is activated, which moves the baffle 8 upward to block the conveying channel of the PCB substrate, preventing it from entering the next stage. At the same time, the pusher 13 moves forward to push the PCB substrate onto the collection rack 14 for uniform collection, thereby realizing the automatic screening of non-conforming PCB substrates. After completion, the baffle 8 moves downward to reset, and the pusher 13 moves backward to reset, and the device enters the working cycle.

[0021] Combination Figure 1 and Figure 3As shown, the collection rack 14 is provided with a groove 15, which provides space for the PCB substrate to be picked up, so as to prevent the PCB substrate from being too close to the collection rack 14 and causing inconvenience in picking it up; the device also includes: a guide plate 16 fixedly installed on the processing table 1, the guide plate 16 is set in the front-back direction of the right entry end of the conveying component 3, the guide plate 16 is used to guide the PCB substrate to be centered, so that the second vision camera 10 can better capture the appearance image of the PCB substrate; a transparent cover plate 17 fixedly installed on the first processing table 1, the transparent cover plate 17 is used to protect the first vision camera 6 from the safety threat caused by processing debris generated during the PCB substrate processing; a cotton pad 18 fixedly installed on the pusher 13, the cotton pad 18 is set on the side of the pusher 13 that contacts the PCB substrate, so as to reduce the contact force between the pusher 13 and the PCB board and improve the contact safety between the two.
