The present utility model will be described in detail below by taking a vision device as an example.

As shown in fig. 1 to 5, the first shielding structure 100 includes a main body, an opening and closing device 120, and a driving device 130. The body has a vision inspection channel 110 disposed therein, the vision inspection channel 110 being disposed below a lens 321 of the vision apparatus 300 (as shown in fig. 5).

More specifically, the cylinder 132 is a rodless cylinder. The rodless cylinder can avoid faults caused by damage of the piston rod and the sealing ring, and has the same thrust force because the compression areas of the two sides of the piston are equal, thereby being beneficial to improving the positioning precision. In addition, the stroke of the rodless cylinder is longer.

The sliding block 133 thereon is driven to move along the X-axis direction by the driving of the air cylinder 132, so that the moving riser 121 and the opening and closing plate 122 at the bottom side of the moving riser 121 move along the X-axis direction to open or close the visual inspection channel 110.

The moving riser 121 is disposed substantially vertically on the opening and closing plate 122, so that a side portion of the moving riser 121 may be coupled with the slider 133, thereby being driven from a side wall of the opening and closing plate 122, and thus interference with the vision apparatus 300 above the opening and closing plate 122 may be prevented.

As shown in fig. 1 and 3, the opening plate 122 and the moving riser 121 are also connected by a connection plate 123. Specifically, the opening plate 122 is provided with a first connection groove 124 and a positioning groove 125 extending in a moving direction (X direction) thereof, respectively, the moving plate 121 is provided with a second connection groove 126, and when the moving plate 121 is disposed in the positioning groove 125, the first connection groove 124 and the second connection groove 126 are aligned with each other, so that both sides of the connection plate 123 are disposed in the first connection groove 124 and the second connection groove 126, respectively.

The movable vertical plate 121 can be stably mounted on the opening plate 122 through the positioning groove 125, so that the movable vertical plate 121 is prevented from being inclined, and when the second connecting groove 126 on the movable vertical plate 121 is aligned with the first connecting groove 124 on the opening plate 122, both sides of the connecting plate 123 can be respectively placed into the second connecting groove 126 and the first connecting groove 124, so that the connection between the movable vertical plate 121 and the opening plate 122 can be enhanced.

As shown in fig. 1 and 2, the main body includes first and second guide plates 111 and 112 disposed opposite to each other, the first and second guide plates 111 and 112 extending parallel to each other in the X direction, and a space between the first and second guide plates 111 and 112 forms a visual inspection channel 110. And the first guide plate 111 and the second guide plate 112 are respectively provided with a guide groove 116 (as shown in fig. 3), and both sides of the opening plate 122 are respectively movably arranged in the guide grooves 116 so as to ensure the moving stability of the opening plate 122.

The sealing plate 113 may define a limit position of the opening plate 122, and when the opening plate 122 abuts against the sealing plate 113, the visual inspection channel 110 is closed, so as to form a sealed environment, so as to protect the lens 321 above the sealing plate. The sealing plate 113 may be made of polyurethane material, so that when it abuts against the opening and closing plate 122, a sealing structure can be formed, and functions of dust prevention and water prevention. In addition, the sealing plate 113 made of polyurethane material can also play a role of buffering, and can absorb a part of impact force of the movement of the opening plate 122, so as to avoid the influence on the vision device 300 caused by the transmission of the impact force.

As shown in fig. 3, sealing structures are disposed on the first guide plate 111, the second guide plate 112, and a side of the opening and closing plate 122 away from the sealing plate 113. In some embodiments, the sealing structure is configured as a sealing plate 127, and the sealing plate 127 is made of silica gel, so that the opening and closing plate 122 forms a sealing moving mechanism with the first guide plate 111 and the second guide plate 112 to secure a protective effect.

As shown in fig. 3, the other side end (right side end) of the first guide plate 111 and the other side end (right side end) of the second guide plate 112 are further connected to a base plate 114, and the base plate 114 is further connected to a vision device 300; the bottom plate 114 is also provided with a sump 115. Since the cutting machine sprays liquid such as cooling water or the like onto the workpiece 500 (e.g., silicon rod) during operation, the liquid may splash onto the first guard structure 100, and thus it is required to collect the liquid through the liquid collecting tank 115 and drain the liquid outward so as not to affect the vision apparatus 300.

As shown in fig. 6 to 9, the second protective structure includes a protective cover 210, the protective cover 210 accommodates the first protective structure 100 and the vision device 300 (as shown in fig. 9), and a photographing hole 211 (as shown in fig. 6) is provided at a position of the bottom of the protective cover 210 corresponding to the vision inspection channel 110.

When the opening plate 122 is moved in the X-axis direction to open the visual inspection passage 110, the lens 321 may perform photographing through the visual inspection passage 110 and the photographing hole 211.

As shown in fig. 6, the bottom of the protection cover 210 is respectively provided with a bracket 230 connected with the lifting mechanism, the bracket 230 includes a support plate 231 connected with the bottom end of the protection cover 210 and a fixing frame 232 connected with the support plate 231, and the support plate 231 is provided with a avoiding groove 233 corresponding to the photographing hole 211. The supporting plate 231 is coupled to the shield 210 to support the shield 210, and the fixing frame 232 is coupled to the cutting device 400 described below to fixedly couple the shield 210 to the cutting device 400. The fixing frame 232 may be a tripod structure to improve the stability of connection.

Since the protection cover 210 is mounted on the cutting device 400, the cutting device 400 may collide with the adjacent cutting device 400 during movement, collision between the adjacent cutting devices 400 can be avoided through the contact limit switch 242, and when the contact limit switch 242 is touched, the contact limit switch 242 sends out a signal, so that the cutting device 400 (or the cutting device 400 adjacent thereto) can be controlled to stop moving.

As shown in fig. 7, the protective cover 210 is further provided with a waterproof connector 250 for connecting cables and an air inlet connector 260 for introducing air into the protective cover 210, respectively. The air inlet connector 260 can continuously introduce air into the protective cover 210, so that liquid, dust and the like in the protective cover 210 can be blown out of the protective cover 210, and the influence on the vision device 300 is avoided.

As described in fig. 7 and with reference to fig. 3, a drain hole 270 for draining the liquid accumulation in the shield 210 is further formed at the bottom of the shield 210.

As shown in fig. 7, the second protective structure 200 further includes a protective door plate 220 provided at one side of the protective cover 210, and a gasket is provided at an inner side of the protective door plate 220. The shield door 220 and the shield 210 may be formed in a sealing structure by a gasket.

It is conceivable that a link plate, which links with the above-described shutter plate 122, may also be covered on the photographing hole 211. That is, when the opening plate 122 moves along the positive direction of the X-axis, the linkage plate can be driven to move synchronously, so that the opening plate 122 opens the visual detection channel 110 and the linkage plate also opens the shooting hole 211, and the lens 321 can shoot through the visual detection channel 110 and the shooting hole 211; on the contrary, when the opening and closing plate 122 moves along the negative direction of the X-axis, the linkage plate can be driven to move synchronously, so that the opening and closing plate 122 closes the visual detection channel 110, and the linkage plate also closes the shooting hole 211, so that the visual detection channel 110 and the shooting hole 211 are both closed, and the lens 321 is protected.

Therefore, the linkage plate functions such that when the lens 321 is closed, the vision detecting passage 110 is closed and the photographing hole 211 is also closed, so that the second protective structure 200 forms a completely sealed integral structure accommodating the vision device 300 therein, thereby improving the protective effect thereof.
