[0016] Figure 3 for Figure 2 Sectional view in . DETAILED DESCRIPTION

[0017] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Figure 1-3 The invention comprises 1-roller, 2-buffer wheel, 3-swing arm, 4-handle, 5-magnet, 6-suction plate, 7-first cover plate, 8-first limit rod, 9-second limit rod, 10-spring, 11-cylinder, 12-fixing ring, 13-origin trigger plate, 14-limit position trigger plate, 15-origin position photoelectric switch, 16-limit position photoelectric switch, 17-bottom plate, 18-rotating sleeve, 19-rotating shaft, 20-second cover plate, 21-bearing, 22-vertical plate, 23-magnet bracket and the like.

[0019] like Figure 1-3 As shown, the present invention is a structure of a silicon wafer detection device, including an execution drive device, the execution drive device is vertically arranged, the moving end of the execution drive device is connected to the upper end of the vertical plate 22, the lower end of the vertical plate 22 is connected to the bottom plate 17, the middle of the bottom plate 17 is provided with a mounting boss, the rotating sleeve 18 is rotatably installed in the mounting boss, the upper and lower ends of the mounting boss are respectively provided with a first cover plate 7 and a second cover plate 20, the first cover plate 7 and the second cover plate 20 are respectively connected to the upper and lower ends of the rotating sleeve 18 by bolts, the rotating shaft 19 is rotatably installed in the rotating sleeve 18 through a bearing 21, the upper and lower parts of the rotating shaft 19 are extended out of the rotating sleeve 18, the upper part of the rotating sleeve 18 is installed with a fixed ring 12 and an origin trigger plate 13, and the side of the fixed ring 12 is horizontally installed with a second limit rod 9. The first limit rod 8 is vertically arranged on the top of the first cover plate 7, the first limit rod 8 is connected to one end of the spring 10, and the other end of the spring 10 is connected to the origin trigger plate 13. The lower end of the rotating shaft 19 is fixedly connected to the swing arm 3, and the roller 1 is installed at the lower part of the swing arm 3. A suction plate 6 is installed below the first cover plate 7 , and a magnet 5 is installed on the bottom plate 17 .

[0020] An origin detection switch is provided on the side of the mounting boss.

[0021] In this embodiment, the execution driving device is a cylinder 11 , the limit position detection switch is a limit position photoelectric switch 16 , and the origin position detection switch is an origin position photoelectric switch 15 .

[0022] In order to enable the structure to sound an alarm in the event of failure, a limit position triggering piece 14 is provided below the origin triggering piece 13, and a limit position detection switch is provided below the origin position detection switch.

When the silicon wafer contacts the buffer wheel 2 during the forward movement, it drives the swing arm 3 to swing clockwise, and the swing arm 3 drives the rotating shaft 19 and the origin trigger plate 13 to rotate clockwise at the same time. When the origin trigger plate 13 blocks the origin position photoelectric switch 15, the photoelectric signal is fed back to the PLC to notify the cylinder 11 to lift and separate the detection mechanism from the silicon wafer. The origin trigger plate 13 rotates counterclockwise under the contraction of the spring 10 until the second limit rod 9 presses against the first limit rod 8, and the swing arm 3 is reset.

[0028] As shown in the figure: if the origin position photoelectric switch 15 is damaged, the swing arm 3 continues to swing clockwise, and when the limit position trigger sheet 14 blocks the limit position photoelectric switch 16, the machine alarms and stops.

[0029] When maintenance is needed, manually pull 4 to drive the rotating sleeve 18, the first cover plate 7, and the suction plate 6 to rotate counterclockwise to disengage the magnet 5.
