[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a glass slide scanner with an automatic focus function, including a shell 1, the shell 1 is the main body of the glass slide scanner, and the scanner inside the shell 1 has an automatic focus function to maintain the best focal length during imaging. This is a prior art well known to professionals in the field and will not be repeated here. The outer wall of the shell 1 is provided with a placement opening 5, and the inner wall of the placement opening 5 is provided with a loading mechanism 2. By inserting the loading mechanism 2 into the placement opening 5, the glass slide on the loading mechanism 2 can be scanned. The outer wall of the shell 1 is provided with a supporting mechanism 3, and the supporting mechanism 3 can support the loading mechanism 2 after it is inserted into the placement opening 5, so that the loading mechanism 2 and the glass slide rack 4 are more stable.

[0035] Reference Figure 2-Figure 3 The loading mechanism 2 includes a tray 201, which is detachably mounted inside the placement port 5. The slide rack 4 can be placed on the tray 201, and the tray 201 is inserted into the placement port 5 and moved to the inside of the shell 1 for scanning. The outer wall of the tray 201 is provided with multiple groups of card slots 202. The arrangement of the multiple groups of card slots 202 allows the fixing plate 203 to be moved to multiple positions and fixed, thereby adapting to slide racks 4 of different sizes. The inner wall of the tray 201 is detachably mounted with the slide rack 4. The slide to be scanned can be placed on the slide rack 4 and scanned by a scanner with automatic focus inside the shell 1.

[0036] Reference Figure 2-Figure 3 The inner wall of the tray 201 is slidably connected with a fixing plate 203, and the fixing plate 203 is moved horizontally and fixed on the inner wall of the tray 201, so that the glass slide rack 4 can be fixed, and it can adapt to glass slide racks 4 of different sizes, and has higher adaptability. The inner wall of the fixing plate 203 is slidably connected with a trapezoidal block 204, and the top of the trapezoidal block 204 passes through the top outer wall of the fixing plate 203. The trapezoidal block 204 can be moved downward by pressing the top of the trapezoidal block 204. The inner wall of the fixing plate 203 is slidably connected with two sets of connecting rods 205. When not affected by external force, the wedge block 207 is ejected to both sides by the elastic force of the spring A206 itself, driving the connecting rod 205 to maintain contact with the long side of the trapezoidal block 204. At this time, the top outer wall of the trapezoidal block 204 is flush with the top outer wall of the fixing plate 203.

[0037] Reference Figure 2-Figure 3One end of the connecting rod 205 is fixedly connected to the outer wall of the wedge block 207, and the other end of the connecting rod 205 is slidably connected to the outer wall of the trapezoidal block 204. When the trapezoidal block 204 is pressed downward, the two groups of connecting rods 205 move from the long side of the trapezoidal block 204 to the short side, and move toward the middle under the guidance of the inner wall of the fixed plate 203, thereby driving the two groups of wedge blocks 207 to move toward the middle. A limiting component is set on the inner wall of the fixed plate 203, and the position of the fixed plate 203 can be fixed by the limiting component.

[0038] Reference Figure 3 The limit assembly includes wedge blocks 207. Two groups of wedge blocks 207 are provided and symmetrically distributed in the inner walls of both sides of the fixed plate 203. The wedge blocks 207 are elastically connected to the inner wall of the fixed plate 203 through springs A206. When the fixed plate 203 moves to the left, the arc surface of the wedge blocks 207 is squeezed by the inner wall of the slot 202, so that the wedge blocks 207 move inward along the inner wall of the fixed plate 203, and the fixed plate 203 can be moved. One end of the spring A206 is fixed The spring A206 is fixedly connected to the inner wall of the fixing plate 203, and the other end of the spring A206 is fixedly connected to the outer wall of the wedge block 207. When the fixing plate 203 moves to contact the outer wall of the glass slide rack 4, the wedge block 207 pops outward due to the elastic force of the spring A206 itself, and the straight surface of the wedge block 207 contacts the inner wall of the card slot 202, thereby limiting the fixing plate 203 in one direction, so that the fixing plate 203 will not move away from the glass slide rack 4, and the glass slide rack 4 is fixed.

[0039] Reference Figure 3 The outer wall of the wedge block 207 is slidably connected to the inner wall of the fixed plate 203, and the wedge block 207 is engaged with the card slot 202. When the position of the fixed plate 203 needs to be adjusted to the right to accommodate a larger glass slide rack 4, the trapezoidal block 204 can be pressed downward, and the wedge block 207 can be driven to move to the middle through the connecting rod 205. The wedge block 207 is out of contact with the card slot 202, and the limit of the fixed plate 203 can be released, and the fixed plate 203 can be moved.

[0040] Reference Figure 4-Figure 5 The supporting mechanism 3 includes a supporting rod 303, which is hinged to the outer wall of the shell 1. The supporting rod 303 can be flipped upward and drive the two sets of baffles 304 to flip simultaneously to support the tray 201. The outer wall of the supporting rod 303 is hinged with a slider 302 through a rotating rod 301. The slider 302 is slidably connected to the outer wall of the shell 1. The slider 302 can be moved upward and the supporting rod 303 can be flipped upward by the rotating rod 301. One end of the rotating rod 301 is hinged to the outer wall of the slider 302, and the other end of the rotating rod 301 is hinged to the outer wall of the supporting rod 303. When the sliding rod 302 moves upward, it drives the rotating rod 301 to flip. Since the outer wall of the top end of the supporting rod 303 is hinged to the outer wall of the shell 1, the supporting rod 303 can be flipped upward by the rotating rod 301.

[0041] Reference Figure 4-Figure 5 The outer wall of the support rod 303 is fixedly connected with a baffle 304, and two groups of baffles 304 are provided. The two groups of baffles 304 are symmetrically distributed on the outer walls of both sides of the support rod 303. The inner wall of the slider 302 is elastically connected with a block 306 through a spring B305. The block 306 is cylindrical, and the front end outer wall of the block 306 is provided with a square protrusion. The position of the block 306 can be adjusted by turning the protrusion. One end of the spring B305 is fixedly connected to the outer wall of the block 306, and the other end of the spring B305 is fixedly connected to the inner wall of the slider 302. When not affected by external force, the spring B305 drives the block 306 to remain in a pop-up state due to its own elastic force, and is engaged with the groove 307, so that the position of the slider 302 can be fixed.

[0042] Reference Figure 4-Figure 6 The outer wall of the card block 306 is slidably connected with the inner wall of the slider 302. When the slider 302 needs to be moved, the protrusion set on the outer wall of the card block 306 can be moved to make the card block 306 move inward along the inner wall of the slider 302, so that the card block 306 and the groove 307 are out of contact. The slider 302 is moved up and down, and the card block 306 is engaged with the groove 307. When the slider 302 moves to the position where the card block 306 corresponds to the groove 307, the elastic force of the spring B305 drives the card block 306 to pop outward. , and engaged with the groove 307, the position of the slider 302 can be fixed, the outer wall of the shell 1 is provided with two groups of grooves 307, and the grooves 307 are provided with upper and lower groups. When the block 306 is engaged with the upper group of grooves 307, the support rod 303 and the baffle 304 can be flipped upward to support the tray 201. The outer wall of the shell 1 is provided with a slide groove 308. When the protrusion provided on the outer wall of the block 306 is moved to move the protrusion to the inner wall of the slide groove 308, the slider 302 can be moved up and down.

[0043] Working principle: the operator can first place the glass slide rack 4 on the tray 201 and adjust the position of the fixing plate 203 to fix the glass slide rack 4. When the fixing plate 203 needs to be adjusted to the left, the fixing plate 203 can be directly moved to the left. The arc surface of the wedge block 207 is squeezed by the force of the card slot 202, so that the wedge block 207 moves inward along the inner wall of the fixing plate 203, and the fixing plate 203 can be moved to the left. When the fixing plate 203 needs to be moved to the right, the trapezoidal block 204 can be pressed downward to move the two groups of connecting rods 205 along the long side of the trapezoidal block 204 to the short side, and drive the two groups of wedge blocks 207 to move toward the middle, so that the wedge block 207 can be disengaged from the card slot 202, thereby releasing the limit of the fixing plate 203 and moving the fixing plate 203 to the right. The position of the fixing plate 203 can be adjusted to adapt to glass slide racks 4 of different sizes.

[0044] When the fixing plate 203 moves to fit the outer wall of the glass slide rack 4, the spring A206 drives the wedge block 207 to pop outward due to its own elastic force, so that the wedge block 207 is engaged with the card slot 202, and the fixing plate 203 is limited in one direction, so that the fixing plate 203 cannot move away from the glass slide rack 4, thereby fixing the position of the fixing plate 203 and fixing the glass slide rack 4. When multiple groups of glass slide racks 4 are installed on the tray 201 and fixed, the tray 201 can be inserted into the shell 1 along the placement opening 5, so that the shell 1 has a The scanner with autofocus function scans the glass slide, and because the placement opening 5 penetrates the outer wall of the shell 1, the glass slide rack 4 after scanning is moved outward from the placement opening 5 on the other side of the shell 1, and the operator can unload the glass slide rack 4 of this part, and place the glass slide rack 4 to be scanned on the tray 201 to repeat the above steps for installation, and move the tray 201 in the opposite direction to scan again, so that loading and unloading can be carried out during the scanning process, and multiple groups of glass slide racks can be scanned one by one continuously, saving time and improving work efficiency.

[0045] When the tray 201 is inserted into the shell 1, the operator can move the protrusion provided on the outer wall of the block 306 to make the block 306 move inward along the inner wall of the slider 302 and disengage from the groove 307, thereby releasing the limit of the slider 302, moving the slider 302 upward, and driving the support rod 303 and the baffle 304 to flip upward by the rotating rod 301. When the slider 302 moves to the position where the block 306 corresponds to the position of the upper group of grooves 307, the block 306 pops outward due to the elastic force of the spring B305 and engages with the groove 307, thereby fixing the slider 302, fixing the support rod 303 and the baffle 304, and supporting the tray 201, so that the glass slide rack 4 is more stable during the scanning process. When not in use, the protrusion provided on the outer wall of the block 306 can be moved, and the slider 302 can be moved downward, so that the support rod 303, the rotating rod 301 and the baffle 304 can be folded up, saving space and facilitating operation.
