[0018] Example

[0019] like Figure 1-2 As shown, a device for hoisting a silicon wafer turnover basket is mainly composed of a suspension rod 2, a lifting mechanism 3 and a clamping mechanism; wherein the lifting mechanism 3 adopts a conventional cylinder, the clamping mechanism is fixedly connected to the lower end of the lifting mechanism 3, and moves up and down with the lifting mechanism 3. The clamping mechanism includes a fixed seat 21 and a cleaning assembly, and the suspension rod 2 is symmetrically installed on both sides of the fixed seat 21. The top two sides of the fixed seat 21 are fixedly installed with linear slide rails 6, and the linear slide rails 6 are provided with a slide seat 61. The suspension rod 2 is fixedly connected to the slide seat 61, so that the suspension rod 2 can move along the linear slide rail 6 with the slide seat 61. The hanging rod 2 moves left and right, and a pair of slots 26 are provided on the hanging rod 2, which cooperate with the supporting rod on the silicon wafer flower basket 1. When in use, the slide seat 61 is located at the outer edge of the linear slide rail 6. When the lifting mechanism 3 drives the fixed seat 21 to move downward, the hanging rod 2 will not collide with the silicon wafer flower basket 1. When the hanging rod 2 is lowered to the point where its slot 26 is located below the supporting rod, the slide seat 61 moves toward the inside of the linear slide rail 6, so that the slot 26 is located directly below the supporting rod. As the lifting mechanism 3 moves upward, the supporting rod is inserted into the slot 26, so that the silicon wafer flower basket 7 rises to above the liquid medicine pool along with the device.

[0020] The cleaning component is arranged on the fixing seat 21. By arranging the cleaning component, a part of the residual liquid on the silicon wafer 11 is scraped off, so as to avoid the formation of watermarks affecting the product quality and prevent the residual liquid from dripping when the silicon wafer 11 is transferred, causing the ground to be wet. The cleaning component includes a connecting seat 4, a fixing plate 41 connected to the connecting seat 4 through a telescopic structure 5, and a plurality of wiper rubber strips 42 connected to the lower end of the fixing plate 41; wherein the width of the wiper rubber strips 42 matches the spacing between two adjacent silicon wafers 11, and the spacing between two adjacent wiper rubber strips 42 matches the width of the silicon wafer 11; a groove 43 is provided at the bottom end of the connecting seat 4, the telescopic structure 5 is embedded in the inner wall of the groove 43, and the output end of the telescopic structure 5 is connected to the fixing plate 41, and the groove 43 is provided on the inner wall of the groove 43. A guide groove 431 corresponding to the end of the fixing plate 41 is provided on the inner wall of the groove 43, and the lower end of the guide groove 431 passes through the connecting seat 4; an open groove 22 is provided at the bottom end of the fixing seat 21, and a slide groove 23 is provided on the inner wall of the open groove 22, and a cylinder 24 is installed in the slide groove 23, and a slider 25 is connected to the output end of the cylinder 24, one end of the slider 25 is slidably connected with the slide groove 23 through the cylinder 24, and the other end is fixedly connected to the connecting seat 4, so that the connecting seat 4 can move left and right relative to the fixing seat 21. By designing the sliding connection between the connecting seat 4 and the fixing seat 21, the number of wiper rubber strips 42 on a single fixing plate 41 can be reduced, and the stability of the structure of the fixing plate 41 and the wiper rubber strip 42 can be improved.

[0021] When in use, the output end of the telescopic structure 5 is first extended to drive the fixed plate 41 and the wiper strip 42 to move downward, and the wiper strip 42 is inserted between adjacent silicon wafers 11 to scrape off the residual liquid medicine on the silicon wafer 11. Then, the output end of the telescopic structure 5 is contracted to drive the fixed plate 41 to move upward and into the connecting seat 4, and then the connecting seat 4 is driven to move to the right by the cylinder 24, and the above actions are repeated to scrape off the liquid medicine on the remaining silicon wafers 11.
