Description

Technical Field

[0001] This invention relates to the field of laser planar measurement, specifically to a laser measurement device for planar detection of touch components. Background Technology

[0002] Laser planar inspection is a precision measurement method that uses laser technology to inspect flatness, smoothness, and surface shape. It is mainly used in machining, manufacturing, and engineering construction to check whether products or structural components meet design requirements for flatness and surface finish. Laser planar inspection offers advantages such as high precision, high efficiency, non-contact operation, and non-destructive testing, and is widely used in various high-precision measurements and surface morphology analyses.

[0003] The basic principle of laser plane detection is to obtain the geometric information of the plane by measuring the degree of reflection or deflection of the laser beam relative to the plane being measured. This is typically done using laser displacement sensors or laser scanners, including but not limited to...

[0004] Laser displacement sensor: This device emits a laser beam that shines onto the plane to be measured, and the laser beam is reflected by the plane surface. The sensor calculates the change in distance between the laser and the surface based on the time or phase difference of the reflected laser, thereby achieving accurate measurement of the plane shape.

[0005] Laser scanners: Laser scanners scan the plane to be measured by rotating a laser beam or using an array of multiple sensors to acquire distance data at multiple points, and then construct a planar or three-dimensional surface model. This method is particularly suitable for large-area planar inspection.

[0006] However, existing laser planar inspection technologies mostly use a single laser device to emit laser light and detect the planarity of a single point on the device. Then, as the laser device moves, it collects several convergence points to complete the laser planarity inspection. However, the device is prone to errors in planar data detection due to vibration during movement, so there is room for improvement. Summary of the Invention

[0020] 2. Since the touch base is connected to the filter box, specifically the filter box including a filter chamber and a frame, the frame is fixedly connected to the filter box, the filter chamber is opened inside the filter box, the touch base is connected to the filter chamber, and the touch base includes a non-rotating touch base and a rotating touch base. Both the non-rotating touch base and the rotating touch base have drainage holes inside, which are connected to the filter chamber. Therefore, before the touch device is placed on the non-rotating touch base or the rotating touch base, cleaning fluid can be sprayed onto the non-rotating touch base or the rotating touch base through the spray pipe to clean the bottom wall of the non-rotating touch base or the rotating touch base and keep the bottom wall clean, thereby avoiding the problem of impurities in the container affecting the flatness test.

[0021] 2. Since the servo motor is fixedly installed on one side of the mounting base, the output end of the servo motor is fixedly connected to the first lead screw. The first lead screw nut is sleeved on the outside of the first lead screw and movably connected to the first lead screw. A mounting bracket is fixedly connected to one side of the first lead screw nut. The laser detection sensor is movably connected to the mounting bracket, and a second lead screw is rotatably connected inside the mounting bracket.

At the same time, a transmission bevel gear is fixedly connected to the end of the first lead screw away from the servo motor. The two sets of transmission bevel gears mesh with each other. Therefore, by swinging the rotating component, the individual rotation or coordinated rotation of multiple first lead screws can be controlled, thereby reducing the energy consumption of the equipment modulation during measurement and saving energy.
