Description

Technical Field

[0001] The utility model relates to a grating line synchronization structure and belongs to the technical field of gratings. Background Art

[0002] Grating sensor systems are widely used in many fields, such as automated detection, transportation and logistics, and safety protection. In some work sites, there are various interference sources such as electromagnetic, ambient light, and polluted light. If these interference sources are not properly handled, they will often cause the grating to work unstably. When the installation positions are not equal, it is easy to cause the sensitivity of the sensor to decrease. Utility Model Content

[0003] The purpose of the utility model is to provide a grating line synchronization structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a grating line synchronization structure, including a vertical pole, a mounting bracket, a grating, a mounting pipe clamp, an installation station identification line, a laser emission module, a laser calibration module, and a joint. The grating outer shell is sprayed with an installation station identification line, and the laser emission module and the laser calibration module are independently installed at the installation station identification line positions of two groups of gratings, and a joint is installed for electrical connection at the bottom of the grating.

[0005] Preferably, the laser emission module consists of a U-shaped bracket, a tightening screw and a laser emitter. The tightening screw is threadedly installed on the side wall of the U-shaped bracket, and the laser emitter is installed on the front end surface of the U-shaped bracket.

[0006] Preferably, the laser calibration module consists of a U-shaped bracket, a tightening screw and a laser marking lens. The tightening screw is threadedly installed on the side wall of the U-shaped bracket, and the laser marking lens is installed on the front end surface of the U-shaped bracket.

[0007] Preferably, the laser marking lens is composed of a prism, a light-proof sleeve, a reflective lens and a rear light-shielding film. The prism is embedded in the inner diameter of the light-proof sleeve, and the reflective lens and the rear light-shielding film are sequentially installed at the rear end of the prism.

[0008] Preferably, the receiving end and the transmitting end of the grating are built-in with a synchronous decoding module and a synchronous encoding module.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The synchronous decoding and synchronous encoding modules can realize grating light synchronization and line synchronization. After the initial installation of the grating is completed, the laser transmitter of the laser emission module emits a laser beam to illuminate the laser marking lens station of the laser calibration module. If the installation station is synchronized, the laser beam illuminates the prism, the light is dispersed, and the light-proof sleeve and the rear shading film form a dark light environment. The light can only be reflected by the reflective lens, and the light spot reflection formed by the protective glass outside the laser marking lens can be intuitively observed.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-Figure 6 As shown, a grating line synchronization structure includes a vertical pole 1, a mounting bracket 2, a grating 3, a mounting pipe clamp 4, an installation position identification line 5, a laser emission module 6, a laser calibration module 7, and a joint 8. The vertical pole 1 is installed in combination with the mounting bracket 2, the grating 3 is fixedly installed on the pole body of the vertical pole 1 through the mounting pipe clamp 4, the outer shell of the grating 3 is sprayed with an installation position identification line 5, the laser emission module 6 and the laser calibration module 7 are independently installed at the installation position identification line 5 positions of two groups of gratings 3, and the bottom of the grating 3 is electrically connected with a joint 8.

[0020] The laser emission module 6 is composed of a U-shaped bracket 9, a tightening screw 10 and a laser emitter 11. The tightening screw 10 is threadedly installed on the side wall of the U-shaped bracket 9, and the laser emitter 11 is installed on the front end surface of the U-shaped bracket 9. The laser beam of the laser emitter 11 irradiates the laser calibration module 7.

[0021] The laser calibration module 7 is composed of a U-shaped bracket 9, a tightening screw 10 and a laser marking lens 12. The tightening screw 10 is threadedly installed on the side wall of the U-shaped bracket 9, and the laser marking lens 12 is installed on the front end surface of the U-shaped bracket 9. The laser calibration module 7 radiates laser beams.

[0022] The laser marking lens 12 is composed of a prism 13, a light-proof sleeve 14, a reflective lens 15 and a rear light-shielding film 16. The prism 13 is embedded in the inner diameter of the light-proof sleeve 14. The reflective lens 15 and the rear light-shielding film 16 are sequentially installed at the rear end of the prism 13. The laser beam irradiates the prism 13, and the light is dispersed. The light-proof sleeve 14 and the rear light-shielding film 16 form a dark light environment. The light can only be reflected by the reflective lens 15. The light spot reflection formed by the protective glass outside the laser marking lens 12 can be directly observed.

[0023] The receiving end and the transmitting end of the grating 3 are built with a synchronous decoding module and a synchronous encoding module to achieve optical synchronization and line synchronization of the grating 3.

[0024] Specific usage: A grating line synchronization structure, synchronous decoding and synchronous encoding modules can realize grating light synchronization and line synchronization. After the initial installation of the grating is completed, the laser transmitter of the laser emission module emits a laser beam to illuminate the laser marking lens station of the laser calibration module. If the installation station is synchronized, the laser beam illuminates the prism, the light is dispersed, and the light-proof sleeve and the rear shading film form a dark light environment. The light can only be reflected by the reflective lens. The light spot reflection formed by the protective glass outside the laser marking lens can be intuitively observed. Otherwise, it is judged that the installation station is inconsistent.

[0025] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
