[0019] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] like Figures 1-3 As shown, this utility model discloses a glass slide suction device. The device is provided with a support 1, and a first bracket 10 and a second bracket 11 are respectively provided at both ends of the support 1. A guide rail 12 is provided between the first bracket 10 and the second bracket 11. The two ends of the lead screw 13 are respectively rotatably installed on the first and second brackets. A motor 2 is connected to the lead screw 13 and drives it to rotate.
[0021] The lead screw 13 drives the platform 3 to move along the guide rail 12. A long rod 4 is installed at one end of the platform 3. The long rod 4 is provided with a through hole 41 along the axial direction. A flexible suction member 40 is installed at the free end of the long rod 4.
[0022] The stage 3 is equipped with a pressure sensor 5 and a suction device 6. The stage 3 has a first connecting hole 31 and a second connecting hole 32. The first connecting hole 31 connects the suction device 6 to the through hole 41. One end of the second connecting hole 32 communicates with the first connecting hole 31, and the other end of the second connecting hole 32 is connected to the pressure sensor 5. The pressure sensor 5 is used to detect changes in air pressure within the orifice, and the suction device 6 is used to control the gas flow within the orifice.
[0023] like Figure 1 , Figure 2 As shown, the suction device 6 is located at the end of the platform 3 facing the first support 10, the long rod 4 is located at the end of the platform 3 facing the second support 11, and the pressure sensor 5 is located at the end of the platform 3 away from the guide rail 12.
[0024] Combination Figure 1 , Figure 2 As shown, the bottom surface of the platform 3 is a slide 14, the slide 14 is rotatably connected to the lead screw 13, the slide 14 moves along the guide rail 12, and the platform 3 is detached and installed on the slide 14.
[0025] Specifically, in combination Figure 1 , Figure 2As shown, the motor 2 is located on one side of the first bracket 10, and a limit switch 7 is installed on the first bracket 10. The platform 3 is provided with a trigger end 30 on the side facing the first bracket 10. The trigger end 30 extends toward the first bracket 10 and is used to trigger the limit switch 7. The limit switch 7 is a photoelectric switch.
[0026] Specifically, in combination Figure 3 As shown, the connection between the long rod 4 and the platform 3 is sealed by a sealing ring 8, the connection between the suction device 6 and the platform 3 is sealed by a sealing ring 8, and the connection between the pressure sensor 5 and the platform 3 is sealed by a sealing ring 8; the first connecting hole 31 and the second connecting hole 32 are vertically connected.
[0027] It should be noted that the flexible suction member 40 is provided with air holes, which connect its side facing the glass slide and the through hole 41. The suction device 6 can be an air suction device. In the initial state, the air suction device is in the closed state, and one end of the first connecting hole 31 is blocked. The operator controls the long rod 4 to move down to perform slide suction. When the flexible suction member 40 contacts the slide, the operator starts the air suction device to suction inward. Or, when the flexible suction member 40 contacts the slide and is compressed to a certain extent, the volume of the aperture space formed by the air hole, the through hole 41, the first connecting hole 31 and the second connecting hole 32 shrinks, and the air pressure increases. The pressure sensor 5 detects the increase in air pressure and determines that slide suction is to be performed. At this time, the air suction device sucks inward to create negative pressure, so that the slide is adsorbed on the suction surface of the flexible suction member 40. Then the operator controls the long rod 4 to move up and remove the slide. When it is necessary to put the slide down, the operator controls the long rod 4 to move down. When it reaches the required placement position, the air suction device will balance the internal and external air pressure and blow air into the aperture space, so that the slide on the flexible suction member 40 falls to the required position. Furthermore, in some embodiments, the suction device 6 may also be a solenoid valve.
[0028] In summary, this application enables convenient and quick upward and downward movement of glass slides without damaging the surface of the slides, reducing the workload of staff when handling slides; its structure is simple and does not occupy too much space on the operating table.
[0029] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
