[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example:

[0026] As attached Figure 1 To the attached Figure 4 As shown:

[0027] The utility model provides a camera module welding appearance inspection device, which includes a base frame 10, and two sets of baffles 11 are arranged on the top of the base frame 10. These baffles 11 can effectively prevent the camera module being inspected on the crawler 14 from sliding out of the crawler 14, ensuring that the camera module is always on the crawler 14. Multiple sets of transmission rods 13 are arranged between the two sets of baffles 11. The surfaces of the multiple sets of transmission rods 13 are surrounded by the same set of crawlers 14. The user can install the crawlers 14 on the surfaces of the multiple sets of transmission rods 13, so that when the transmission rods 13 rotate, the crawlers 14 can normally transmit the camera module. One set of baffles 11 is connected to the mounting plate 15 by screws, and the rotating motor 1 6 is installed on the top of the mounting plate 15. Before installing the crawler 14 and the transmission rod 13, the user can pass the screw through one side of one group of baffles 11, and then align the threaded hole on the mounting plate 15 with the screw, and screw the screw to fix the mounting plate 15 on one side of one group of baffles 11, so as to install the rotary motor 16. One side of one group of transmission rods 13 is connected to the rotary motor 16, which serves as the power source of the transmission rods 13. When the rotary motor 16 is working, the main shaft rotates, thereby driving one group of transmission rods 13 to rotate, and the crawler 14 drives the other groups of transmission rods 13 to rotate in the same direction, so that the crawler 14 can work normally.

[0028] Among them, see Figure 2 As shown, a control module 203, an A / D converter 205 and a laser radar lens 201 are arranged above the crawler 14. The control module 203 can be the MYC-YA15XC-T model of Mil Electronics, which has strong processing capabilities and short processing time; the A / D converter 205 can be the ADC128D818CIMTX / NOPB model of Shenzhen Maixinda Electronic Technology Co., Ltd., which has a small specification and is easy to install; the laser radar lens 201 can be the Zenmuse L2 model of DJI, which has high resolution and can scan and image objects with high precision; an inkjet component is arranged above the crawler 14, and the inkjet component can mark unqualified camera modules with inkjet.

[0029] Both sides of the two groups of baffles 11 are provided with multiple groups of groove clamps 12 arranged in sequence. The user can insert the first mounting bracket 18 and the second mounting bracket 20 into the groove clamps 12 to install the first mounting bracket 18 and the second mounting bracket 20. A mounting groove is provided at the bottom of the second mounting bracket 20, and the laser radar lens 201 is clamped in the mounting groove. The user can directly insert the laser radar lens 201 into the mounting groove to complete the installation of the laser radar lens 201. The A / D converter 205 is arranged on the top of the second mounting bracket 20. A protective box 202 is fixedly connected to the top of the second mounting bracket 20. The control module 203 is installed in the protective box 202. A protective cover 204 is provided on the top of the protective box 202. Through the cooperation of the protective box 202 and the protective cover 204, the control module 203 installed inside is protected, thereby extending the service life of the control module 203.

[0030] The inkjet assembly includes an ink cartridge 181. The user can inject wipeable ink into the ink cartridge 181. After marking the unqualified camera module, the user can wipe the ink on the camera module to eliminate the ink on the surface of the unqualified camera mold, thereby avoiding the ink remaining on the surface of the camera module and causing damage to the camera module. The ink cartridge 181 is installed on the top of the first mounting bracket 18. The top of the first mounting bracket 18 is provided with a cylinder 182. The cylinder 182 is electrically connected to the control module 203. The inkjet assembly also includes an electric nozzle 183. The electric nozzle 183 is electrically connected to the control module 203. The user can connect the electric nozzle 183 to the ink cartridge 181 through an external catheter, so that The erasable ink in the ink cartridge 181 can be sprayed out by the electric nozzle 183 to mark the unqualified camera mold. The electric nozzle 183 is provided at the bottom of the cylinder 182. The pneumatic rod of the cylinder 182 passes through the first mounting frame 18 and is connected to the electric nozzle 183. When the cylinder 182 is working, the pneumatic rod can drive the electric nozzle 183 to move in the same direction. When the cylinder 182 is working, the pneumatic rod of the cylinder 182 moves toward the direction of the track 14 to ensure that when the electric nozzle 183 is marking the camera mold with ink, the electric nozzle 183 is close to the camera mold, so that the ink sprayed by the electric nozzle 183 is directly sprayed onto the unqualified camera mold, avoiding the erasable ink sprayed by the electric nozzle 183 from being sprayed onto the track 14.

[0031] Two groups of conduits 17 are provided on the top of the crawler 14, and one side of the two groups of conduits 17 is respectively connected to the two groups of baffles 11. The conduit 17 can make the camera mold transported by the crawler 14 pass directly under the electric nozzle 183, preventing the camera mold from not passing directly under the electric nozzle 183 when being transported on the crawler 14. One side of the two groups of baffles 11 is respectively connected to the base frame 10 by screws. The user can remove the screws by screwing them. When the screws are removed, the base frame 10 and the two groups of baffles 11 are released, and the user can remove the baffles 11 and the base frame 10.

[0032] Among them, see Figure 2 、 Figure 3 and Figure 4 As shown, the cylinder 182 and the electric nozzle 183 are connected to the control module 203, and the control module 203 can control the cylinder 182 and the electric nozzle 183 to start or shut down. The laser radar lens 201 is connected to the A / D converter 205, and the laser radar lens 201 can transmit the image analog signal to the A / D converter 205 in one direction. The A / D converter 205 is connected to the control module 203, and the A / D converter 205 can convert the image analog signal output by the laser radar lens 201 into an image digital signal, and transmit it in one direction to the control module 203. The user can connect an external server to the device, compare and judge the image digital signal through the external server, and feed back the result to the control module 203.

[0033] The user can connect the device to an external power supply, and the device can start working. Then the user can place the camera module to be inspected on the crawler 14, and transport the camera module to the bottom of the laser radar lens 201 through the crawler 14. The laser radar lens 201 scans and images the camera module passing below, and outputs the image analog model to the A / D converter 205. The A / D converter 205 can convert the analog signal into a digital signal, convert the image analog signal of the laser radar lens 201, convert it into a picture digital signal and transmit it to the control module 203. After the control module 203 receives the picture digital signal transmitted by the A / D converter 205, it transmits it to the external service. The external server compares and judges it, and then feeds back the result to the control module 203. If the result is qualified, the control module 203 does not take any action, and the qualified camera mold continues to move forward with the crawler 14. If the result is unqualified, the control module 203 controls the cylinder 182 and the electric nozzle 183 to start after a delay, and inkjet marks the unqualified camera mold. The user can set the delay time for starting the cylinder 182 and the electric nozzle 183 for the control module 203 according to the transmission speed of the crawler 14 to avoid the electric nozzle 183 starting to perform inkjet marking when the unqualified camera mold has not yet been transmitted to the bottom of the electric nozzle 183, causing ink to be sprayed onto the crawler 14.
