[0001] The utility model relates to the technical field of optical detection, in particular to an optical detection device with automatic focusing. Background Technique
[0002] An optical detection device is a device that detects common defects encountered in welding production based on optical principles. AOI is a newly emerging new testing technology, but it has developed rapidly, and many manufacturers have launched AOI testing equipment. When automatically detecting, the machine automatically scans the PCB through a camera, collects images, compares the tested solder joints with the qualified parameters in the database, and through image processing, checks for defects on the PCB and displays / marks the defects through a display or an automatic marker for maintenance personnel to repair.
[0003] Existing optical detection devices have certain problems when detecting cultural relics. They often directly place the cultural relics on the detection board and cannot clamp and fix them. When staff use the eyepiece for focusing and observation, they cannot detect them well, which affects the detection accuracy of cultural relics, easily leads to data deviation, and affects the results. In view of the above problems, we propose an optical detection device with automatic focusing for improvement and upgrading. Content of the Utility Model
[0004] The purpose of the utility model is to provide an optical detection device with automatic focusing to solve the problems raised in the above background technique.
[0005] To solve the above problems, the following technical solutions are provided:
[0006] Design an optical detection device with automatic focusing, including a detection machine table. In the middle of the upper end face of the detection machine table, there is an installation seat, and a rotating disk is arranged outside the installation seat. A fixing rod is fixedly connected to the outer wall of the rotating disk, and a worm is arranged at one end of the fixing rod. A worm gear is meshed with the outer wall of the worm, and a threaded rod is arranged in the middle of the worm gear. A side rod is threadedly connected to the outer wall of the threaded rod, and a detection placement plate is fixedly arranged on the upper end face of the side rod. A support frame is arranged behind the installation seat. An installation buckle is sleeved on the outer wall of the support frame, and a fixing frame is fixedly arranged on the outer wall of the installation buckle. A bidirectional lead screw is rotatably installed inside the fixing frame, and two clamping plates are symmetrically arranged on the outer wall of the bidirectional lead screw.
[0007] Furthermore, an electric telescopic frame is arranged on the outer wall of the support frame above the fixing frame. A detection eyepiece is arranged on the lower end face of the electric telescopic frame, and a display screen is fixedly installed on the outer wall of the support frame.
[0008] Furthermore, both the worm and the worm gear are rotatably installed inside the installation seat. One end of the threaded rod is fixedly connected to the worm gear, and the rotating disk is rotatably connected to the outer wall of the installation seat.

[0010] Further, a limiting groove is formed inside the fixing frame, one end of the bidirectional lead screw is fixedly connected with a threaded knob, and the inner parts of the two clamping plates are in threaded connection with the bidirectional lead screw.
[0011] Further, limiting blocks are arranged on both the upper and lower sides of the clamping plate and the limiting blocks are slidably connected inside the limiting groove, and protective pads are fixedly arranged on the outer walls of the two clamping plates.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. Components such as a threaded knob, a fixing frame, a bidirectional lead screw, clamping plates, protective pads, and limiting blocks are arranged inside the device of the present utility model. By rotating the threaded knob, the bidirectional lead screw inside the fixing frame rotates, so that the two clamping plates on the outer wall drive relative movement to clamp and fix the cultural relic.

A support frame 2 is arranged behind the mounting seat 3. An installation buckle 10 is sleeved on the outer wall of the support frame 2, and a fixed frame 6 is fixedly arranged on the outer wall of the installation buckle 10. A bidirectional lead screw 20 is rotatably installed inside the fixed frame 6, and two clamping plates 11 are symmetrically arranged on the outer wall of the bidirectional lead screw 20.
[0025] Preferably, an electric telescopic frame 8 is arranged on the outer wall of the support frame 2 above the fixed frame 6. A detection eyepiece 7 is arranged on the lower end surface of the electric telescopic frame 8. A display screen 9 is fixedly installed on the outer wall of the support frame 2, which is convenient for stable focusing of the movement of the eyepiece and convenient for detecting cultural relics. The worm 14 and the worm gear 15 are both rotatably installed inside the mounting seat 3. One end of the threaded rod 17 is fixedly connected to the worm gear 15. The rotating disc 12 is rotatably connected to the outer wall of the mounting seat 3, which is convenient for the worm gear 15 to stably drive the threaded rod 17 to rotate. A fixed cylinder 16 is fixedly arranged on the upper end surface of the mounting seat 3. Two sliders 19 are fixedly arranged on the outer wall of the side rod 18 and the sliders 19 are slidably connected to the inner wall of the fixed cylinder 16, which is convenient for limiting when the side rod 18 drives the detection placement plate 4 to lift and lower.
[0026] Preferably, a limiting groove 21 is opened inside the fixed frame 6. One end of the bidirectional lead screw 20 is fixedly connected to a threaded knob 5. The two clamping plates 11 are internally threaded with the bidirectional lead screw 20, which is convenient for the two clamping plates 11 to move relatively to clamp and fix the cultural relics.
