Description

Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a cover glass covering device. Background Art

[0002] The main function of the coverslip is to keep solid samples flat and liquid samples formed into a flat layer of uniform thickness. In addition, it holds the sample in place (by the weight of the coverslip, or, in the case of moisture, by surface tension) and protects the sample from evaporation, dust, and accidental contact. Currently, the use of coverslips lacks standardized batch operation tools, and manual operation one by one is cumbersome and prone to accidental contact.

[0003] The utility model patent with application number CN202123305751.9 discloses a cover glass suction device, which includes a frame, a slide seat slidably arranged on the frame, and a carrier box arranged below the slide seat, the carrier box is used to hold the cover glass, the slide seat is provided with a sealing head, and the sealing head is provided with an adsorption device for adsorbing the cover glass. The cover glass suction device adsorbs the cover glass through the suction cups 1 and 2 on the sealing head, so as to automatically adsorb the cover glass and cover it on the slide.

[0004] However, after the cover glass suction device absorbs the cover glass, the staff needs to manually remove the carrier box. Moreover, when cover glass is needed in batches, the staff needs to manually place the slides one by one under the cover glass suction device, which reduces the efficiency of cover glass covering and needs to be improved.

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figures 1 to 6 As shown, a cover glass covering device includes a workbench 1, on which a conveyor belt 2 extending laterally is provided. Specifically, a mounting groove 3 is provided on the top of the workbench 1, and two support rollers arranged in parallel on the left and right are rotatably installed in the mounting groove 3. The support rollers extend forward and backward, and one of the support rollers is driven to rotate by a motor. The conveyor belt 2 is tensioned and sleeved on the two support rollers, and the upper surface of the conveyor belt 2 is arranged flush with the top of the workbench 1.

[0025] like Figure 1 and Figure 2 As shown, a drive box 4 is fixedly installed on the workbench located at the rear side of the conveyor belt 2 by bolts, and a cantilever 5 driven to rise and fall by a power device is installed on the drive box 4. Specifically, the front side of the drive box 4 is open, and the rear end of the cantilever 5 is located in the drive box 4; a vertically extending guide rod 6 is fixedly installed in the drive box 4 by bolts, and the cantilever 5 is vertically slidably installed on the guide rod 6, thereby playing a guiding role in the lifting and lowering of the cantilever 5; a screw rod 8 driven to rotate by a second motor 7 is also provided in the drive box 4, and the screw rod 8 is arranged parallel to the guide rod 6, and the upper end of the screw rod 8 is fixedly connected to the rotating shaft of the second motor 7 through a coupling, and the second motor 7 is installed on the top of the drive box 4 by bolts, and the lower end of the screw rod 8 is rotatably installed on the bottom wall of the drive box 4 through a bearing, and the cantilever 5 is threadedly connected to the screw rod 8, and the screw rod 8 is driven to rotate by the second motor 7, and the cantilever 5 is driven to slide up and down along the guide rod 6 by the rotation of the screw rod 8. The front end of the cantilever 5 extends horizontally to the top of the conveyor belt 2 and is installed with a cover glass suction device 9.

[0026] like Figure 1 and Figure 3 As shown, support plates 10 are fixedly installed on the workbench 1 located on the front and rear sides of the conveyor belt 2 by bolts, and slideways 11 extending left and right along the length direction of the conveyor belt 2 are fixedly installed on the inner sides of the two support plates 10 by bolts, and the two slideways 11 are C-shaped with their mouths arranged opposite to each other. A carrying plate 12 is slidably installed between the two slideways 11, and a mounting groove 13 is provided on the top of the carrying plate 12, and a cover glass placement box 14 is clamped in the mounting groove 13.

[0027] Two parallel support shafts 15 are rotatably installed between the two support plates 10. The support shafts 15 extend forward and backward along the width direction of the conveyor belt 2. The two support shafts 15 are both offset from the bottom of the coverslip suction device 9, and the two support shafts 15 are both located on the same side of the coverslip suction device 9. In this embodiment, the two support shafts 15 are both located on the right side below the coverslip suction device 9, thereby preventing the support shafts 15 from blocking the coverslip suction device 9 from placing the coverslip downward.

[0028] like Figure 3 and Figure 4 As shown, the two support plates 10 are respectively the driven shaft on the left and the driving shaft on the right, the front and rear ends of the driven shaft are rotatably mounted on the corresponding support plates 10 through bearings, the rear end of the driving shaft is fixedly connected to the rotating shaft of the first motor 16 through a coupling, the first motor 16 is mounted on the rear support plate 10 through bolts, and the front end of the driving shaft is rotatably mounted on the front support plate 10 through a bearing; support rollers 17 are coaxially fixedly mounted in the middle of the two support shafts 15, a drive belt 18 is tensioned between the two support rollers 17, an extension plate 19 extending to the right is fixedly mounted on the top of the load-bearing plate 12 by bolts, a connecting block 20 is fixedly mounted on the bottom of the extension plate 19 by bolts, and the connecting block is fixedly connected to the top of the drive belt 18 by bolts.

[0029] When in use, the staff first stacks the multiple cover glasses to be used vertically in the cover glass placement box 14, and first drives the driving belt 18 to rotate counterclockwise through the first motor 16, and then the driving belt 18 drives the carrying plate 12 to slide to the left through the extension plate 19, and drives the cover glass placement box 14 to move to the left to just below the cover glass suction device 9 through the carrying plate 12; then, the second motor 7 drives the screw rod 8 to rotate in a specific direction to drive the cantilever 5 to lower, and the cantilever 5 drives the cover glass suction device 9 to enter the cover glass placement box 14 downward and adsorb the position at the top cover glass; after the cover glass suction device 9 absorbs the cover glass, the second motor 7 drives the screw rod 8 to rotate in the opposite direction, thereby driving the cantilever 5 to rise and return to its original position, and the cantilever 5 drives the cover glass suction device 9 and the cover glass at the bottom of the cover glass suction device 9 to move upward and out of the cover glass placement box 14; after completing the above actions, the first motor 16 drives the driving belt 18 to rotate clockwise, and then the driving belt 18 drives the supporting plate 12 to slide to the right through the extension plate 19, so that the supporting plate 12 and the cover glass placement box 14 deviate to the right from the bottom of the cover glass suction device 9.

[0030] While the cover glass suction device 9 absorbs the cover glass, the staff can place the slide glass to be placed on the conveyor belt 2 upstream of the cover glass suction device 9, and convey the slide glass to the bottom of the cover glass suction device 9 through the conveyor belt 2. When the cover glass suction device 9 absorbs the cover glass and the carrier plate 12 and the cover glass placement box 14 deviate to the right from the bottom of the cover glass suction device 9, the second motor 7 drives the cantilever 5 to lower, and the cantilever 5 drives the cover glass suction device 9 to lower and approach the slide glass on the conveyor belt 2 below it, and the cover glass suction device 9 stops absorbing the cover glass, so that the cover glass is automatically covered on the slide glass.

[0031] While the coverslip suction device 9 is adding the coverslip onto the glass slide, the staff can place the next glass slide on the conveyor belt 2 located upstream of the coverslip suction device 9; after the coverslip suction device 9 adds the coverslip onto the glass slide below it, the second motor 7 drives the cantilever 5 and the coverslip suction device 9 to rise and return to their original positions, and then the next glass slide is conveyed to the bottom of the coverslip suction device 9 by the conveyor belt 2 for standby use, thereby improving the efficiency of coverslip covering.

[0032] like Figure 5As shown, the cover glass suction device 9 includes an adsorption head 21, and two suction cups 22 are installed at the bottom of the adsorption head 21. The suction cups 22 are accordion-type suction cups, and the two suction cups 22 are arranged front and back along the length direction of the cantilever 5. The adsorption head 21 is provided with an air suction component for forming a negative pressure in the suction cup 22. The air suction component is connected to the two suction cups 22 through pipelines, and solenoid valves are respectively provided on the two pipelines to control the opening and closing of the two suction cups 22 separately. A connecting seat 23 is integrally formed at the rear end of the adsorption head 21, and two ear plates 31 are arranged opposite to each other at the bottom of the cantilever 5. The connecting seat 23 is rotatably installed between the two ear plates 31 through a laterally extending hinge shaft 32, and an adjustment mechanism for adjusting the angle of the adsorption head 21 is provided on the cantilever 5.

[0033] Specifically, when the carrier plate 12 drives the cover glass placement box 14 to move to the left to just below the cover glass suction device 9, the angle adjustment mechanism drives the suction head 21 to rotate to a horizontal state so that the heights of the two suction cups 22 remain consistent. When the cantilever 5 drives the suction head 21 downward into the cover glass placement box 14, the cover glass at the top is simultaneously sucked by the two suction cups 22. In addition, a contact switch 33 is also installed at the bottom of the suction head 21 between the two suction cups 22. The bottom surface of the contact switch 33 is not lower than the bottom of the suction cup 22. When the contact switch 33 contacts the cover glass at the top, it means that the two suction cups 22 have stably contacted the cover glass.

[0034] After the cantilever 5 drives the adsorption head 21 and the cover glass at the bottom of the adsorption head 21 to move upward and out of the cover glass placement box 14, the angle adjustment mechanism drives the adsorption head 21 to rotate to an inclined state, so that the cover glass at the bottom of the adsorption head 21 is in an inclined state; when the cover glass placement box 14 deviates to the right from the bottom of the cover glass suction device 9, the second motor 7 drives the cantilever 5 to be lowered to a preset height, and the cantilever 5 drives the adsorption head 21 and the cover glass to be lowered, so that the lower end of the cover glass first contacts the slide glass, and first the higher suction cup 22 stops adsorbing the cover glass, and then the lower suction cup 22 stops adsorbing the cover glass, so that the cover glass is slowly covered on the slide glass in an inclined state, thereby avoiding the generation of bubbles between the slide glass and the cover glass.

[0035] like Figure 6As shown, the adjustment mechanism includes a lever 24 fixedly mounted on the top of the connecting seat 23, the lever 24 extends vertically, and the lower end of the lever 24 is provided with an external thread and screwed on the connecting seat 23; a through slot 25 is vertically penetrated on the cantilever 5, one end of the through slot 25 is connected to the front end of the cantilever 5, and the left and right side walls of the through slot 25 are respectively provided with slide grooves 26 extending forward and backward along the length direction of the cantilever 5, and a push plate 27 driven by a driving device to move forward and backward is slidably installed between the two slide grooves 26, and the driving device is an electric push rod 28. The front end of the cantilever 5 is fixedly installed with a mounting frame 29 by bolts, and the body of the electric push rod 28 is fixedly installed on the mounting frame 29 by bolts. The push rod of the electric push rod 28 extends backward, and the front end of the push plate 27 is fixedly installed on the push rod of the electric push rod 28 by bolts.

[0036] The lever 24 passes through the through slot 25 upwards. Since the connecting seat 23 is arranged at the rear end of the adsorption head 21, the lever 24 is pressed forward against the rear side of the push plate 27 under the action of the gravity of the adsorption head 21. The rear side of the push plate 27 is provided with an arc groove matching the lever 24, so that the two can contact stably.

[0037] Specifically, the push plate 27 is moved backward by extending the electric push rod 28, and then the push plate 27 pushes the lever 24 to rotate backward, and the lever 24 drives the front end of the adsorption head 21 to rotate upward to a horizontal state; or the push plate 27 is moved forward by contracting the electric push rod 28, and then the lever 24 rotates forward following the push plate 27, and the front end of the adsorption head 21 rotates downward under the action of gravity, thereby rotating the adsorption head 21 to an inclined state.

[0038] The outer surface of the conveyor belt 2 is marked with positioning frames 30 for placing glass slides, and a plurality of positioning frames 30 are evenly spaced along the length direction of the conveyor belt 2. Specifically, the distance that the conveyor belt 2 moves the glass slide each time is the distance between two adjacent positioning frames 30, so that the conveyor belt 2 can accurately convey the glass slide to the position directly below the adsorption head 21.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
