DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figure 1-6 ;

[0029] The pressing mechanism described in the utility model is suitable for the production of different types of sperm slides, which effectively reduces the production cost; it specifically comprises a base 1, on which a bearing seat 2 and a lifting pressing device 3 are respectively installed; wherein the bearing seat 2 is used to place the processed slide, and the lifting pressing device 3 is used to press and shape the slide; before explaining the working principle, the structure of the slide is first introduced, whether it is a slide for detecting human sperm or a slide for detecting animal sperm, the structure is the same, and the specific reference can be made to the Chinese public patent document "CN206990424U, sperm counting plate", or the Chinese public patent document "CN207703569U, a pig sperm analysis slide", which is specifically composed of two upper and lower slides, wherein the cover has a plurality of openings for dripping sperm so that the sperm is placed on the surface of the film, and the difference between the slides used by humans and animals is the thickness of the space used to place sperm;

[0030] Further, the lifting and pressing device 3 includes a controller, the controller is electrically connected to a servo motor 31, the servo motor 31 is transmission-connected to a screw pair 32, a fixed seat 33 is installed at the movable end of the screw pair 32, at least one micrometer 34 is installed on the fixed seat 33, the end of the micrometer 34 is connected to a pressing seat 35, a corresponding curing lamp 36 and a light-transmitting pressing block 37 are installed on the pressing seat 35, and the light-transmitting pressing block 37 corresponds to the bearing seat 2; based on the above structure, there are multiple implementation methods for slides of different thicknesses:

[0031] In the first embodiment, according to the size of sperm of humans or different animals, cover sheets of different thicknesses are selected, and then glue is applied on the surface of the bottom sheet, and then the cover sheet is placed on the surface of the bottom sheet, and then placed on the supporting seat 2 to wait for pressing. Of course, the space enclosed by different cover sheets and bottom sheets is different to avoid sperm stacking. How to form the enclosed space is different and will not be discussed here;

[0032] Prior to this, by determining the descending stroke of the fixing seat 33 and the pressing seat 35, and then finely adjusting the position of the pressing seat 35 through the micrometer 34, the pressing seat 35 is raised or lowered relative to the fixing seat 33, that is, when pressing a thicker glass slide, the pressing seat 35 is raised through the micrometer 34, and when pressing a thinner glass slide, the pressing seat 35 is lowered through one thousandth. Although the glass slides are thin and thick, they are only a few microns apart, and the micrometer 34 can achieve fine adjustment. After that, the servo motor 31 and the screw pair 32 only need to move according to the fixed stroke. Of course, the servo motor 31 and the screw pair 32 can achieve fine movement to ensure that the stroke is fixed and accurate.

[0033] In the second embodiment, according to the size of sperm of humans or different animals, cover sheets of different thicknesses are selected, and then glue is applied on the surface of the bottom sheet, and then the cover sheet is placed on the surface of the bottom sheet, and then placed on the supporting seat 2 to wait for pressing. Of course, the space enclosed by different cover sheets and bottom sheets is different to avoid sperm stacking. How to form the enclosed space is different and will not be discussed here;

[0034] In this embodiment, the positions of the fixing seat 33 and the pressing seat 35 are not adjusted by the micrometer 34. Of course, the micrometer 34 needs to be used for debugging before leaving the factory, and then it is fixed. At this time, the thickness information of the glass slide is obtained in advance. Of course, the corresponding information of the glass slide and the corresponding movement stroke are recorded in the system. You only need to select it. Select the corresponding pressing stroke according to the actual situation. Through the cooperation of the servo motor 31 and the screw pair 32, high-precision movement and descent can be achieved, so that the transparent pressing block 37 is pressed on the surface of the glass slide.

[0035] The third embodiment is based on one of the first and second embodiments, and does not distinguish thickness. The surface of the bottom film is glued and then the cover film is placed on the surface. At this time, the two are not pressed together, and there is a movable distance between the cover film and the bottom film. By controlling the pressing distance of the light-transmitting pressing block 37 with high precision, that is, controlling the pressing distance of the cover film to the bottom film, chambers of different heights are formed to meet the detection of sperm of humans or different animals; refer to Figure 7 When the cover is pressed down a long distance, the gap between the cover and the bottom film will be very small, that is, the height of the chamber is small, and the internal space of the chamber is small. This type of slide is suitable for detecting human sperm; when the cover is pressed down a short distance, the gap between the cover and the bottom film will be large, that is, the height of the chamber is large, and the internal space of the chamber is large. It is suitable for detecting sperm with larger volume and avoiding sperm stacking.

[0036] It should be noted that the volume of pig sperm is larger than that of human sperm. Therefore, when testing human sperm, a slide with a smaller chamber may be required, while when testing pig sperm, a slide with a larger chamber may be used.

[0037] Regardless of which of the above methods is used, the light-transmitting pressing block 37 will eventually be pressed onto the upper surface of the glass slide and apply a certain pressure. At the same time, the curing lamp 36 shines on the glass slide through the light-transmitting pressing block 37 to fix the glue and achieve a tight connection between the two glass slides. In this embodiment, the light-transmitting pressing block 37 is made of quartz glass to increase wear resistance and light transmittance.

[0038] The utility model can realize the production of slides with different chamber heights according to needs through the adjustment of the high-precision servo motor 31, the screw pair 32 and the micrometer 34, has strong applicability and effectively improves production efficiency.

[0039] The cam 325 is provided with a plurality of support members 322, each of which is provided with a plurality of guide grooves 323. The guide grooves 323 are provided on the inner sides of the support members 322, and the guide grooves 323 extend along the direction of the cam 321. The cam 325 is provided with at least one protrusion 324 on both sides of the cam 325 and is slidably connected with the guide grooves 323. The cam 326 is provided on both sides of the cam 325, and the cam 326 abuts against the surface of the support members. The support members 322 can protect the cam 325 and reduce the interference caused by the external environment. In addition, the position of the cam 325 can be limited by the setting of the protrusions 324 and the guide grooves 323. At the same time, the end of the arc limiting plate 326 has a pressing effect on the surface of the support member 322, and cooperates with the protrusions 324 to further limit the position of the cam 325 to avoid displacement and make its operation more stable.

[0040] The utility model is described with respect to an implementation method of a micrometer 34;

[0041] When the number of micrometer 1 34 is one, it should be installed in the middle of the fixing seat 33. Of course, a plurality of guide posts can be arranged between the fixing seat 33 and the pressing seat 35 to prevent the pressing seat 35 from shifting left and right.

[0042] When there are four micrometers 34, they are respectively connected to the four corner positions of the pressing seat 35. The four micrometers 34 can not only adjust the distance between the fixing seat 33 and the pressing seat 35, but also the pressing seat 35 is not parallel to the supporting seat 2 due to the error between the components. Therefore, the balance of the pressing seat 35 can be finely adjusted by the four micrometers 34 to meet the pressing processing requirements.

[0043] Based on the above two embodiments, a locking structure can also be set between the fixing seat 33 and the pressing seat 35 to limit the relative position of the two. When adjustment is required, the locking structure can be unlocked and the position can be adjusted by a micrometer 34. After the adjustment is completed, the two can be locked by the locking structure.

[0044] One of the embodiments of the support seat 2 of the utility model specifically includes an adjustment component and a base plate 22, the base plate 22 is slidably connected to a middle plate 23 along the Y-axis, the middle plate 23 is slidably connected to an upper plate 24 along the X-axis, and the upper plate 24 is rotatably connected to a turntable 25, the adjustment component is used to adjust the position between the above two adjacent components, the X-axis and Y-axis referred to in this embodiment are used to distinguish the movement directions of the two, and the specific direction depends on the actual situation, the plane adjustment of the middle plate 23 and the upper plate 24 can be achieved through the adjustment component, and the turntable 25 is cooperated to achieve the adjustment of the plane angle, wherein a position for placing a slide is provided on the turntable 25, corresponding to the light-transmitting pressing block 37.

[0045] Further, the adjustment assembly includes a micrometer 2111 fixed on one side of the bottom plate 22, a micrometer 3 2121 fixed on the middle plate 23, and a micrometer 4 2131 and an elastic member 2132 fixed on the upper plate 24 and arranged opposite to each other;

The bottom plate 22 and the middle plate 23 are locked by the fixing sheet 2113 and the screw 2114. When adjustment is required, the screw 2114 is unscrewed, and then the fixing block 2112 is driven to move by the second micrometer 2111, so that the middle plate 23 and the bottom plate 22 can slide relative to each other, and then the screw 2114 is passed through the fixing sheet 2113 and connected to the middle plate 23 to achieve fixation.

[0047] A second fixing block 2122 is provided on one side of the upper plate 24, and the second fixing block 2122 is connected to the end of the third micrometer 2121. A second fixing sheet 2123 is provided on one side of the middle plate 23, and a second screw 2124 passes through the second fixing sheet 2123, and the second screw 2124 is connected to the upper plate 24; when adjustment is required, the second screw 2124 is unscrewed, and then the second fixing block 2122 is driven to move by the third micrometer 2121, so as to realize the relative sliding of the upper plate 24 and the middle plate 23, and then the second screw 2124 is passed through the second fixing sheet 2123 and connected to the upper plate 24 to realize fixation;

[0048] A lever is extended transversely on one side of the turntable 25, and the lever is placed between the ends of the micrometer 2131 and the elastic member 2132. The upper plate 24 is provided with a movable screw 2133, and the screw 2133 is connected to the lever. A slot 261 rotatably connected to the turntable 25 is provided on the middle plate 23, and an arc groove 263 is provided at the position corresponding to the lever. The lever passes through the arc groove 263 and extends to the position of the micrometer 2131 and the elastic member 2132. In addition, a strip hole 262 is provided corresponding to the screw 2133, and one end of the screw 2133 passes through the strip hole 262. The hole 262 is connected to the end of the lever, and the nut at the other end abuts against the outer periphery of the strip hole 262; the screw three 2133 abuts against the upper plate 24 when the lever is tightened, thereby fixing the position of the turntable 25 and the upper plate 24; when adjustment is required, the screw three 2133 is loosened, and then the lever is pushed by the micrometer four 2131, and at the same time, the elastic member 2132 will be compressed. Conversely, the thousandth retraction of the elastic member 2132 will push the lever to move in the opposite direction, thereby realizing the angle adjustment of the turntable 25, and finally the screw three 2133 can be re-tightened.

[0049] Of course, the position adjustment mentioned above belongs to fine-tuning, and the precise adjustment of the supporting seat 2 is achieved through the mutual cooperation of micrometer 2 2111, micrometer 3 2121 and micrometer 4 2131.
