Description

Technical Field

[0001] This utility model relates to the field of grating equipment technology, specifically an anti-interference grating. Background Technology

[0002] Optical gratings are commonly used in industrial automation inspection, security protection, and logistics sorting as core components for detecting object occlusion and identifying positions, triggering signals and providing feedback through light occlusion sensing. However, existing anti-interference optical gratings suffer from the following problems: First, their protective performance is inadequate; external dust can easily enter through gaps in the housing and the insertion point of the detector rod, moisture can cause short circuits in the internal circuitry, and electromagnetic interference can disrupt signal transmission, reducing detection accuracy. Second, their installation adaptability is poor; the mounting brackets are mostly integrated designs, unable to be flexibly adjusted to the installation dimensions and angles of different equipment racks, limiting their applicability. Third, their internal structure is unreasonable; circuit board assembly is difficult to position, wiring is cumbersome, and subsequent maintenance and disassembly are time-consuming. Furthermore, the stability and sealing of the connection between the grating detector rod and the main body are insufficient, affecting long-term reliability. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an anti-interference grating, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference grating, comprising a grating main body assembly and an installation adapter assembly.

[0007] The grating main body assembly includes a signal connector and a grating main body shell. The signal connector has end sealing caps and signal connection structures at both ends. The end sealing caps are made of rubber sealing material and are interference-fitted with the ends of the signal connector, acting as a "protective barrier" to effectively block the intrusion of external dust and moisture. At the same time, the electromagnetic shielding properties of rubber reduce the entry of electromagnetic interference. The signal connector has an internal circuit board mounting position for signal processing. This mounting position has positioning buckles and conductive contact points. The positioning buckles can quickly "lock" the circuit board for precise assembly. The conductive contact points replace traditional wiring, making signal transmission more direct and stable. In addition, multiple grating detection rods are arrayed at the bottom of the signal connector. These detection rods are made of high light transmittance and anti-interference material and have their own anti-interference ability to ensure the accuracy of light sensing and detection.

[0008] The installation adapter component includes side mounting brackets located on both sides of the bottom end of the signal connector. The side mounting brackets are detachably connected to the signal connector, like "replaceable building blocks". Different specifications of brackets can be flexibly replaced according to installation requirements. The brackets are provided with bracket fixing holes for fixing with external installation structures. With screws and other fasteners, they can be securely connected to equipment racks, etc.

[0009] The grating main body housing is composed of an upper housing and a lower housing located outside the signal connector. The upper and lower housings are spliced ​​and fixed by snaps or screws. A sealing strip is provided at the splice to further enhance the sealing performance of the grating main body housing, acting like a "protective cover" for the internal components. The lower housing has an internal slot and internal reinforcing ribs. The internal slot can assist in the quick mounting of components such as circuit boards, while the internal reinforcing ribs enhance the structural strength of the lower housing and prevent external forces from deforming and squeezing the internal components. A probe hole is provided for the grating probe rod to pass through. A sealing rubber ring is provided between the grating probe rod and the probe hole to seal the gap between them and reduce the entry of external dust and moisture into the grating main body housing.

[0010] As a further improvement of this utility model: the signal connection structure is an aviation plug interface, which has the characteristics of quick plugging and unplugging and anti-interference connection, and is suitable for the cable connection needs of industrial scenarios. Its internal structure design can effectively shield external electromagnetic interference, so that the signal transmission is "smooth all the way".

[0011] As a further improvement of this utility model, the rubber material of the end sealing cap has good elasticity and wear resistance, and is not easily deformed or aged after long-term use, thus continuously ensuring the sealing and protection effect.

[0012] As a further improvement of this utility model: the high-transmittance optical glass of the grating detection rod can accurately sense changes in light, while the anti-interference material can resist external interference such as static electricity and electromagnetic radiation, ensuring accurate detection signals.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a "multi-layer sealing protection system" is constructed by the rubber seal of the end sealing cover, the sealing rubber ring between the grating detection rod and the through hole, and the sealing strip at the splice of the upper and lower shells. This system comprehensively blocks the intrusion of dust and moisture. Combined with the aviation plug interface and the anti-interference design of the detection rod itself, it strongly resists electromagnetic interference, greatly improves the stability and detection accuracy of the grating in complex environments, and extends the service life of the equipment.

[0015] 2. In this utility model, the detachable and replaceable side mounting bracket, along with the bracket fixing holes, is like giving the grating "flexible limbs," which can adapt to different sizes and angles of installation scenarios and easily fix it to various equipment racks; the positioning buckles and conductive contact points of the internal circuit board mounting position make the circuit board assembly "plug and hold," which is convenient for later maintenance, optimizes the installation adaptability and internal structure rationality of the grating, and improves the overall practicality.
