Example two

Further, as shown in fig. 1 and 3, the light foreign object detection structure 3 includes a mounting member 31 and a light sensor 32. The mounting member 31 is provided with two and two mounting members 31 arranged on opposite sides of the wireless device, and the light sensor 32 is arranged on the mounting member 31 on at least one side of the wireless device such that light emitted from the light sensor 32 is directed from one of the mounting members 31 to the other mounting member 31.

It is to be understood that the mounting member 31 in the present embodiment is the mounting structure 31 described above, and the light sensor 32 is the light element 32 described above. As shown in fig. 1, the wireless device has two opposite sides, and two mounting members 31 are respectively mounted on the two opposite sides, the light sensor 32 may be disposed on one of the mounting members 31, or a part of the structure of the light sensor 32 may be disposed on one of the mounting members 31, and a part of the structure of the light sensor 32 may be disposed on the other mounting member 31. Wherein the foreign matter cleaning assembly 5 is connected with the mounting member 31 and is positioned on one side of the mounting member 31 far away from the working surface.

EXAMPLE III

Example four

Further, the light sensor 32 includes an emitting end and a receiving end. In one embodiment, the light sensor 32 is a structure in which the emitting end and the receiving end are integrally disposed, in which case, the light sensor 32 is disposed on one of the mounting members 31, as shown in fig. 1, the light sensor 32 is provided in plural, and the plural light sensors 32 are disposed on one of the mounting members 31 in an array. That is, the plurality of light sensors 32 are arranged along the extending direction of the mounting member 31 and arranged along a straight line.

In another embodiment, the light sensor 32 may also be a structure in which the emitting end and the receiving end are separately disposed, and the emitting end and the receiving end are respectively disposed on the mounting members 31 at two sides of the wireless device. That is, the emitting end of the light sensor 32 is disposed on one of the mounting members 31, the receiving end of the light sensor 32 is disposed on the other mounting member 31, the emitting end and the receiving end are disposed opposite to each other, and when the light sensor 32 is provided in plurality, the emitting end and the receiving end of each light sensor 32 are disposed opposite to each other.

When the foreign matter 10 exists on the working surface, the light emitted from the emitting end is affected by the foreign matter 10, so that the receiving end cannot normally receive the light. Thus, the presence of a foreign object 10 on the work surface is related to whether the receiving end can normally receive light. That is, when the receiving end cannot normally receive the light emitted from the emitting end, the foreign object 10 exists on the working surface, and when the receiving end can normally receive the light emitted from the emitting end, the foreign object 10 does not exist on the working surface. Therefore, whether the foreign matter 10 exists on the working surface can be judged by judging whether the receiving end can normally receive the light, thereby avoiding the use of electric signals.

EXAMPLE five

Further, as shown in fig. 3 and 4, the foreign object cleaning assembly 5 further includes two guide rails 52, two guide members 53, and a guide rod 54, wherein the two guide rails 52 are respectively disposed on the two mounting members 31, the two guide members 53 respectively slide along the two guide rails 52, the guide rod 54 connects the two guide members 53, the extending direction of the guide rails 52 is the same as the extending direction of the mounting members 31, and the cleaning portion 51 is disposed on the side of the guide rod 54 facing the working surface.

When the light foreign matter detection structure 3 detects that foreign matter exists on the working surface, a foreign matter signal is transmitted to the controller, and the controller controls the operation of the driving motor according to the foreign matter signal, so that the driving motor drives the guide piece 53 to drive the cleaning part 51 to move.

EXAMPLE six

Furthermore, in the embodiment of the present invention, the guide rail 52 and the mounting member 31 may be integrally formed, or the guide rail 52 and the mounting member 31 may be separately formed.

Specifically, when the guide rail 52 and the mounting member 31 are integrally formed, the integrity of the guide rail and the mounting member is better, the structure is more stable, and the direct mounting and dismounting are convenient; when the guide rail 52 is formed separately from the mounting member 31, if one of them is damaged, it is convenient to repair or replace it.

The shape of the cleaning portion 51 is not particularly limited, and the shape of the cleaning portion 51 may be specifically set on the premise of ensuring effective cleaning of the working surface.

Example eight

Furthermore, as shown in fig. 5 and 6, the gratings 4 are distributed on the working surface in an array, the foreign object detection assembly 30 further includes a grating structure embedded with the gratings 4, the grating structure is attached to the working surface, at least a portion of the gratings 4 are exposed from openings of the grating structure, and the light sensors 32 are disposed in grooves formed on the grating structure by the adjacent gratings 4. At this time, the light foreign object detection structures 3 are disposed on both sides adjacent to the wireless device. That is to say, when light sensor 32 sets up the structure for transmitting end and receiving end are integrative, two sensors set up the adjacent both sides at wireless device respectively, when light sensor 32 sets up the structure for transmitting end and receiving end components of a whole that can function independently, wireless device is the cuboid structure, and the transmitting end of one light sensor 32 sets up with the transmitting end of another light sensor 32 is adjacent, and the receiving end of one light sensor 32 sets up between the receiving end of another light sensor 32 and the transmitting end of another light sensor 32.

It can be understood that when the gratings 4 are distributed in an array on the working surface, the light sensor 32 is disposed between any two adjacent columns of gratings 4, and the light sensor 32 is also disposed between any two adjacent rows of gratings 4. The grooves are formed between any two adjacent columns of gratings 4 or between any two adjacent rows of gratings 4.

Due to the arrangement of the grating structure, light emitted by the emitting end of the light sensor 32 can be blocked by the grating at the corresponding position of the foreign matter 10 with the smaller size on the working surface, so that the receiving end of the light sensor 32 cannot detect the light, and the foreign matter with the smaller size can also be detected, such as paper and the like.

In the embodiment shown in fig. 5 and 6, the light sensor 32 is disposed on the wireless transmission device 1.

In other embodiments, the light sensor 32 may also be disposed on the wireless receiving device 2, or the light sensor 32 may be disposed on both the wireless transmitting device 1 and the wireless receiving device 2.

In other embodiments, the light sensor 32 may be other, and the type of the light sensor 32 is not particularly limited, and may be specifically selected on the premise of ensuring effective detection of the foreign object.

In other embodiments, when the light sensor 32 is flush with the working surface, the grid structure may be omitted to reduce the structural complexity of the foreign object detection device.

Example nine

Furthermore, as shown in fig. 5 and 6, the foreign object cleaning assembly 5 further includes a lifting structure 6, wherein the lifting structure 6 is fixed to the mounting member 31, and drives the light sensor 32 and the foreign object cleaning assembly 5 to lift relative to the wireless device. Specifically, since the guide rail 52 is fixedly connected to the mounting member 31, when the lifting mechanism 6 drives the mounting member 31 to move up and down, the guide rail 52 is also driven to move up and down, and the guide member 53, the guide rod 54, and the cleaning portion 51 provided on the guide rod 54 are driven to move up and down.

In this embodiment, in order to further improve the foreign object detection effect on the wireless device, the light foreign object detection structures 3 may be disposed on two adjacent sides of the wireless device, the light foreign object detection structures 3 on the two adjacent sides respectively correspond to the transverse direction and the longitudinal direction of the wireless device, and the infrared rays emitted from the two directions intersect with each other, so as to fully cover the working surface of the wireless device, and further improve the detection accuracy on the foreign object. It should be noted that the mounting member 31 is installed around the wireless device, so that when a foreign object is detected on the working surface, the foreign object is blocked by the mounting member 31 and cannot be swept out by the foreign object cleaning assembly 5 (cleaning portion 51). Therefore, in the present embodiment, the lifting structure 6 for driving the light foreign object detection structure 3 and the foreign object cleaning assembly 5 (the cleaning portion 51, the guide rail 52, the guide member 53, and the guide rod 54) to lift relative to the wireless device is added to adjust the positions of the light foreign object detection structure 3 and the foreign object cleaning assembly 5 relative to the working surface, so as to ensure that the foreign objects are effectively cleaned.

Specifically, taking the wireless receiving device 2 shown in fig. 5 and 6 as an example for explanation, when a foreign object appears on the receiving surface 21, the whole lifting structure 6 drives the light foreign object detection structure 3 and the foreign object cleaning assembly 5 (the cleaning part 51, the guide rail 52, the guide member 53, and the guide rod 54) to descend by a certain height relative to the wireless device until the light foreign object detection structure 3 (the mounting part 31 and the light sensor 32) is submerged below the receiving surface 21, the cleaning part 51 can just clean the receiving surface 21, and the periphery of the receiving surface is not shielded by the mounting part 31, so that the cleaning part 51 can sweep the foreign object out of the receiving surface 21, and the feasibility of the scheme is ensured. It can be understood that when the wireless transmitter 1 is also installed with the lifting device 6, and the lifting structure 6 drives the light foreign object detecting structure 3 and the foreign object cleaning assembly 5 to move, the light foreign object detecting structure rises relative to the transmitting surface 11.

More, the lifting structure 6 may be a cylinder structure, a hydraulic structure, a linear motor or a motor transmission structure, etc. The lifting structure 6 comprises a fixed end connected to the wireless device and a movable end connected to at least one of the grid structure and the guide rail 52. The connection mode between the fixed end and the wireless device and the connection mode between the movable end and at least one of the grid structure and the guide rail 52 are not particularly limited, and may be, for example, a bolt connection, an adhesive connection, or the like.

Example ten

Furthermore, in this embodiment, the lifting structure 6 includes a working state and a non-working state, and when the lifting structure 6 is in the working state, the lifting structure 6 drives the guide rail 52 to move away from the wireless device, so that the working surface and the cleaning portion 51 are disposed at an interval. When the lifting structure 6 is in a non-operating state, the lifting structure 6 drives the guide rail 52 to move close to the wireless device, so that the working surface is in contact with the cleaning part 51.

As shown in fig. 5 and 6, when the guide rail 52 and the lifting structure 6 are disposed on the wireless transmitter 1, the lifting structure 6 drives the mounting member 31 and the guide rail 52 to move toward the wireless receiver 2 in the operating state, and the lifting structure 6 drives the mounting member 31 and the guide rail 52 to move away from the wireless receiver 2 in the non-operating state, so that the grating structure contacts the cleaning portion 51.

When the working state, clearance portion 51 is located light sensor 32's top, light sensor 32 can carry out the foreign matter to the working face and detect, and clearance portion 51 can not influence light sensor 32's work, and when the non-working state, clearance portion 51 and working face contact to the foreign matter on the clearance working face, light sensor 32 was located the below of working face this moment, and clearance portion 51 can not cause the influence to light sensor 32 on the installed part 31 when moving on following the working face.

It can be understood that, in the two mounting members 31, a side surface of one of the mounting members 31 facing the other mounting member 31 is flush with one end of the working surface, so that the detection range of the optical sensor 32 disposed on the mounting member 31 can cover the working surface, and the mounting member 31 can be lifted and lowered along the outer surface of the wireless device, at this time, the mounting groove 311 is disposed on the mounting member 31, and the optical sensor 32 is disposed in the mounting groove 311, so that in the process of lifting and lowering the mounting member 31 along the outer surface of the wireless device, friction between the optical sensor 32 and the outer surface of the wireless device is avoided, and the optical sensor 32 is protected.

In other embodiments, when the guide rail 52 and the lifting structure 6 are disposed on the wireless receiving device 2, in an operating state, the lifting structure 6 drives the mounting member 31 and the guide rail 52 to move toward the direction of the wireless transmitting device 1, and in a non-operating state, the lifting structure 6 drives the mounting member 31 and the guide rail 52 to move away from the transmitting device, so that the grating structure contacts the cleaning portion 51.
