The power-on detection information can be detected by external equipment. The appearance detection information can be scanned by a visual recognition device and compared with the standard scanned copy.

[0056] S400: If yes, start the conveyor and mark the circuit board as normal.

[0061] In the optional solution provided by the present invention, the intelligent detection device also includes a correction mechanism, which is installed on the lifting assembly and connected to the control chip; based on this, after the position measuring device recognizes that the circuit board enters the preset area, the position measuring device generates a detection instruction, including the following steps: after the correction mechanism corrects the position of the circuit board, the position measuring device generates a detection instruction. The correction mechanism corrects the position of the circuit board so that the position of the circuit board meets the requirements and avoids detection errors.

[0062] The advantages of the testing equipment are described in detail below: 1. The present invention sets a mechanical arm assembly so that when the conveyor 1 transports the circuit board, the circuit board can be stopped at the position where the detection mechanical arm 5 is located, and then the detection mechanical arms 5 on both sides drive the detection probe 6 to contact the interface or terminal on the circuit board, so that the detection equipment such as the multimeter is connected to the circuit board, so as to perform power-on detection on the circuit board. After the detection of a single interface or terminal is completed, the detection electric slider 3 will drive the detection probe 6 to move horizontally along the detection linear guide rail 2 through the lateral movement base 4, and change the position of the detection probe 6 to connect other interfaces and terminals, so as to detect whether the circuit connection of the circuit board is normal, whether the circuit board can operate normally, and at the same time test the stability of the circuit board operation; 2. The present invention sets a visual recognition device 10, so that before the detection robot 5 drives the detection probe 6 to contact the circuit board for power-on test, the conveyor 1 will first transport the circuit board to the bottom of the visual recognition device 10, so that the visual recognition device 10 can take a picture and scan the circuit board to detect whether the appearance and size of the circuit board meet the requirements, whether there are any missing components or broken or lifted solder feet; 3. The present invention realizes automatic power-on detection and appearance detection of circuit boards by cooperating with the mechanical arm assembly and the visual recognition device 10, greatly improving the automation and intelligence of circuit board detection, reducing the detection time of circuit boards, and greatly reducing the dependence of circuit board detection work on the proficiency of workers; 4. In the present invention, by setting the positioning plate 12 and the guide plate 13, during the process of the conveyor 1 transporting the circuit board, the circuit board will slide in along the inclined surfaces of the guide plates 13 on both sides in sequence, and maintain a state parallel to the guide plates 13 at the narrowest spacing of the guide plates 13, so as to guide and position the circuit board, so that the circuit board is oriented, and then the conveyor 1 stops the transmission, the lifting frame 7 starts to descend, and the suspension frame 8 is driven to descend through the horizontal frame 9, so that the positioning electric push rod 11 falls on the top of the conveyor 1, and the two positioning plates 12 are respectively inserted into the narrowest spacing of the guide plates 13, and are respectively located on both sides of the circuit board, so that the two positioning plates 12 and the two guide plates 13 form a surrounding plate to surround the circuit board inside, and then the two positioning electric push rods 11 drive the positioning plate 12 to move toward the circuit board until the circuit board is clamped. In this process, the circuit board will be pushed by the positioning plate 12 and gradually move to the specified position to realize the positioning of the circuit board, thereby ensuring that the circuit board will be in the same position each time it is detected, which is convenient for the robot arm assembly to detect along the established route, greatly optimizing the positioning process of the robot arm assembly, and reducing the overall detection time; 5. Two upper pressing plates 14 are installed on the side of the two positioning plates 12 facing the circuit board through bolts. The positioning plates 12 on both sides fix the circuit board, and the upper pressing plates 14 press on the side of the circuit board to lock the circuit board, which can prevent the circuit board from shaking or deflecting during the detection process, affecting the detection accuracy; 6. In the present invention, the positioning plate 12, the guide plate 13 and the upper pressing plate 14 are assembled with other components by fastening bolts. Therefore, different positioning plates 12, guide plates 13 and upper pressing plates 14 can be replaced according to the specifications of the circuit board and the distribution of components, and the running route of the robot arm assembly can be re-formulated, so that the detection circuit can be adapted to different types of circuit boards, realizing one machine with multiple uses; 7. The present invention sets a recycling box 15, so that when a multimeter or other detection equipment or a visual recognition instrument 10 detects that the current circuit board has defects or manufacturing problems, the system will mark it according to the different problems, and then the circuit board is released by the positioning plate 12, the lifting frame 7 rises and resets, and the conveyor 1 continues to transport the circuit board. Different recycling boxes 15 are used to recycle circuit boards with different problems. The system transports the problematic circuit board to one side of the designated recycling box 15 according to the type of problem, and then the system controls the recycling electric slider 18 to drive the push rod bracket 19 and the recycling electric push rod 20 to move to the designated position along the recycling linear guide 17. At this time, the recycling electric push rod 20 drives the recycling push plate 21 to move toward the problematic circuit board, so that the circuit board is pushed into the recycling tube 16, and then slides along the recycling tube 16 into the recycling box 15 for storage, thereby realizing the discharge and recycling of the problematic circuit board, eliminating the operation of subsequent identification and screening, and protective structures such as protective pads and buffer plates can be set inside the recycling tube 16 and the recycling box 15 to protect the problematic circuit board to avoid secondary damage and facilitate subsequent recycling.
