Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensors, and in particular to a transparent object recognition and detection device based on photoelectric sensing. Background Technology

[0002] The transparent object recognition and detection device based on photoelectric sensing is a technical device that uses the photoelectric effect to achieve non-contact detection. Its core principle is to identify transparent objects by changes in light signals (such as reflection, refraction, and changes in polarization direction), which effectively solves the problem that traditional sensors are difficult to detect due to the high light transmittance of transparent objects. The transparent object recognition and detection device based on photoelectric sensing generally consists of a photoelectric sensor, a photoelectric sensor fixing device, and a recognition and detection system.

[0003] Existing photoelectric sensors commonly use plate mounting devices. Typically, screw holes are set on the surface of the photoelectric sensor, and screws are used to fix the sensor's position to an L-shaped plate via these screw holes. The L-shaped plate is then fixed to the edge of the conveyor equipment using screws, allowing the photoelectric sensor to identify and detect transparent objects moving inside the conveyor equipment. However, this mounting method requires the photoelectric sensor to be rectangular with screw holes on its surface, limiting the types of photoelectric sensors that can be used. Furthermore, this method is unsuitable for transparent objects with uneven thickness or large transparent objects requiring area-based detection. When detecting transparent objects with uneven thickness or large transparent objects requiring area-based detection, the height of the photoelectric sensor needs to be adjusted according to the object's thickness or area. However, with the above mounting methods, changing the photoelectric sensor height requires replacing the plate, which takes a long time, and the photoelectric sensor may struggle to continuously identify and detect transparent objects during the replacement process.

[0004] In summary, the existing technology of fixing photoelectric sensors by means of surface screw holes and L-shaped plates and screws limits the types of photoelectric sensors that can be used, and makes it difficult to meet the needs of large transparent objects with uneven thickness or requiring regional detection for rapid adjustment of sensor height.

[0044] In some specific implementations, the surface of the fixing plate 1 is provided with a plurality of threaded holes 61;

[0045] In some specific implementations, a support ring 62 for supporting a photoelectric sensor is rotatably connected to the end of the fixing plate 1, and a plurality of fixing straps 63 are slidably connected inside the fixing plate 1.

[0051] When fixing the photoelectric sensor to the fixing plate 1, the photoelectric sensor with the screw hole 63 is directly fixed by the screws corresponding to the threaded holes 61 on the surface of the photoelectric sensor and the fixing plate 1. If fixing a photoelectric sensor without screw holes, first turn out the support ring 62, contact one end of the photoelectric sensor with the support ring 62, then pull the fixing band 63 to make the fixing band 63 contact the surface of the photoelectric sensor, and then slide the locking post 64 into the end of the locking groove 65 to define the fixing position. The fixing band 63 fixes the photoelectric sensor to the surface of the fixing plate 1.

[0052] The base plate 23 is brought into contact with the machine. The base plate 23 and the machine can be directly fixed by screws; or the electric push rod can be controlled to make the clamping plate 24 and the base plate 23 come into contact with the opposite surface of the machine to fix the position of the base plate 23.

[0053] When adjusting the height of the photoelectric sensor, pull the contact ring 33, which drives the shaft 34 and the inclined groove 35 to cause the two positioning rods 31 to disengage from the limiting teeth 51, changing the height of the support plate 21. After the height of the support plate 21 is determined, release the contact ring 33. Under the action of the connecting spring 36, the positioning rods 31 are engaged between the adjacent limiting teeth 51, limiting the height of the support plate 21.

[0054] When changing the positions of the fixed plate 1 and the support plate 21, rotate the pressing rod 53 to disengage the limiting tooth 51 from the connecting tooth 52, allowing the fixed plate 1 to slide. After the fixed position is determined, rotate the pressing rod 53 in the opposite direction to make the limiting tooth 51 contact the connecting tooth 52 to limit the position. Rotate the operating column 43 to disengage the triangular tooth 42 from the protruding tooth 41. Rotate the fixed plate 1 to drive the connecting column 22 to rotate. After the angle of the fixed plate 1 on the surface of the support plate 21 is determined, reverse the operating column 43 to make the triangular tooth 42 and the protruding tooth 41 contact each other, limiting the angle of the fixed plate 1.
