[0020] Embodiment 1: A detection device for a circuit board for an LED lamp, such as Figure 1-5 As shown, it includes a support block, a shell 2, a motor 3, a rotating frame 4, a fixed frame 5, a sliding frame 6, a cylinder 7, a guide rail 8, a slider 9, an optical lens 10, a display 101, a connecting plate 11 and an aperture 111. The support block 1 is used to support the entire device. The shell 2 is fixedly connected between the support blocks 1. The motor 3 is installed on the right side of the shell 2. The motor 3 is used to provide power for rotation. The right side of the shell 2 is rotatably provided with a rotating frame 4. The output shaft of the motor 3 is fixedly connected to the rotating frame 4. The rotating frame 4 will rotate with the rotation of the motor 3. The left side of the rotating frame 4 is fixedly connected with a fixed frame 5. The right side of the rotating frame 4 is slidably provided with a sliding frame 6. The fixed frame 5 and the sliding frame 6 are both composed of two blocks and a connecting rod, and the two blocks on the fixed frame 5 are symmetrically arranged with the two blocks on the sliding frame 6. The sliding frame 6 and the fixed frame 5 will firmly clamp the circuit board on the rotating frame 4 to prevent the circuit board from rotating. Separated from the rotating frame 4, a cylinder 7 is installed on the upper rear side of the shell body 2, and a guide rail 8 is connected to the upper rear side of the shell body 2. A slider 9 is slidably provided on the inner side of the guide rail 8. The telescopic rod of the cylinder 7 is fixedly connected to the slider 9, and the slider 9 will slide left and right with the movement of the telescopic rod of the cylinder 7. An optical lens 10 is installed at the lower part of the slider 9. The optical lens 10 can clearly collect information about the circuit board. A connecting plate 11 is connected to the slider 9, and an aperture 111 is installed at the lower part of the connecting plate 11. The aperture 111 provides illumination light when the optical lens collects information, so as to facilitate clearer collection of details on the circuit board. A display 101 is fixedly installed on the upper part of the shell body 2. Signals are transmitted between the optical lens 10 and the display 101, and the collected image will be displayed on the display 101. The display 101 stores a database of various parameters of qualified circuit boards, and is also provided with a system for data comparison.

[0021] When it is necessary to inspect the circuit board, first place the circuit board on the rotating frame 4, and insert the left side of the circuit board into the two block grooves on the left fixed frame 5, then slide the sliding frame 6 to the left, and fix the circuit board firmly on the rotating frame 4 through the blocks on the sliding frame 6, then start the optical lens 10 and the cylinder 7, the telescopic rod of the cylinder 7 pushes the slider 9, and the slider 9 drives the optical lens 10 to move left and right, and the optical lens 10 scans the entire upward side of the circuit board, and at the same time opens the aperture 111 to irradiate the circuit board below, so as to increase the light intensity and facilitate the optical lens 10 to clearly collect and magnify the image, and the optical lens 10 is connected to the display 101 through signal transmission, and the collected image will be displayed through the display 101, and the display 101 stores various parameters about the qualified circuit board. The display 101 is used to compare the solder joint and line arrangement information collected by the optical lens 10 on the circuit board with the qualified parameters of the database in the display 101, and the defects are automatically marked and displayed through the display 101, so as to effectively improve the detection efficiency and reduce the occurrence of defective products. When the optical lens 10 completes the collection and detection of the upper side of the circuit board, the motor 3 is started, and the motor 3 rotates 180 degrees, driving the rotating frame 4 and the circuit board to rotate 180 degrees, and the circuit board is turned over, and the other side of the circuit board is detected through the optical lens 10 and the display 101. After the detection is completed, the sliding frame 6 is slid to the right so that the sliding frame 6 is out of contact with the circuit board, and the circuit board is taken away, and then the optical lens 10 and the aperture 111 are closed to complete the detection.

[0022] Embodiment 2: Based on embodiment 1, Figure 1-3 As shown, it also includes a measuring tool 12, a sensor 121 and a sensor 2 (13). The measuring tool 12 is connected between the fixed frame 5 and the sliding frame 6. The measuring tool 12 is provided with scale information of the observation distance. The lower part of the sliding frame 6 is connected to the sensor 121. The sensor 121 is in sliding contact with the measuring tool 12. When the sensor 121 moves on the measuring tool 12, the data information on the measuring tool 12 will be transmitted to the display 101. The right part of the sliding frame 6 is connected to the sensor 2 13. The sensor 2 13 will transmit the data of the circuit board thickness to the display 101.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, spotlights 14 are also included. Spotlights 14 are installed on both the front and rear sides of the lower part of the shell 2. The two spotlights 14 shine toward the rotating frame 4. The purpose is to irradiate stronger light so that people can observe the light transmittance of the circuit board through the spotlights 14 before detecting the soldering points and circuits.

[0024] When the circuit board is placed on the rotating frame 4, by turning on the spotlight 14, the light of the spotlight 14 will shine on the circuit board on the rotating frame 4. The light irradiated by the spotlight 14 is relatively strong. Before detecting the solder joints and circuits, people observe the light transmittance of the circuit board through the spotlight 14, and there is no need to additionally detect the light transmittance of the circuit board. When the sliding frame 6 is moved, the sensor 121 on the sliding frame 6 slides on the measuring tool 12. The sensor 121 is a distance sensor. When it moves on the measuring tool 12, it will transmit the data information on the measuring tool 12 to the display 101. When the sliding frame 6 clamps the circuit board, the sensor 121 will transmit the length information at this time to the display 101. The upper and lower sides of the sensor 2 13 will be respectively located on the upper and lower sides of the circuit board. The sensor 2 13 can transmit the data of the thickness of the circuit board to the display 101. The size information of the circuit board is quickly detected by the sensor 121 and the sensor 2 13, without manual measurement, which is more convenient.

[0025] In a preferred embodiment, the motor 3 rotates at an angle of 180 degrees, so as to quickly turn over the circuit board on the rotating frame 4 .

[0026] In a preferred embodiment: the clamping blocks on the sliding frame 6 and the fixing frame 5 are provided with grooves that can clamp the circuit board to prevent it from falling.
