Claims (10)

1. A cover glass sucking and sealing pressing device is characterized by comprising a first sucking head, a second sucking head, a sucking head platform and a reciprocating transfer mechanism, wherein the first sucking head and the second sucking head are fixed at different positions at the bottom of the sucking head platform, the reciprocating transfer mechanism is coupled to the sucking head platform so as to transfer the sucking head platform between a cover glass sucking station and a sealing pressing station in a reciprocating manner, the first sucking head and the second sucking head are triggered to open and suck air to suck a cover glass or close and suck air to release the cover glass on corresponding stations, wherein when the cover glass sucking device is in an intermediate state between sucking action and sealing pressing action, the sucking head platform keeps an inclined state so that the first sucking head is lower than the second sucking head, and when the cover glass sucking device is in an operating state of downward sucking action or sealing pressing action, the first sucking head is firstly jacked up, gradually leveling the tip platform, thereby causing the second tip to participate in a suction action or a flap pressing action with respect to the first tip with a delay; wherein the first suction head and the second suction head have flat suction cups.

2. The cover glass sucking and sealing device according to claim 1, further comprising a movable tip carrier plate, a movable link, a longitudinal support plate, an upper limit block, a lower limit block, and a trigger switch, wherein one end of the tip platform is hinged to a lower end of the movable tip carrier plate, the movable link is obliquely hinged between the other end of the tip platform and the longitudinal support plate, the upper limit block and the lower limit block are fixed to the longitudinal support plate, the movable tip carrier plate is slidably disposed on the longitudinal support plate between the upper limit block and the lower limit block, the shuttle mechanism is coupled to the longitudinal support plate to shuttle the longitudinal support plate between a cover glass sucking station and a sealing plate pressing station, and the trigger switch is disposed on the longitudinal support plate, when the first suction head is in an operation state of downward suction action or pressing the sealing sheet action, the suction head platform gradually tends to be horizontal by means of upward sliding of the movable suction head bearing plate and outward rotation of the movable connecting rod in the process that the first suction head is jacked upwards.

3. The cover glass sucking and sealing device as claimed in claim 2, wherein the longitudinal support plate is provided with a sensing piece, the cover glass sucking station and the sealing piece pressing station are respectively provided with a sensor, and the sensor triggers the reciprocating transfer mechanism to transfer the longitudinal support plate from the current station to the opposite station when sensing the sensing piece.

4. The cover glass sucking and pressing sealing device as claimed in any one of claims 2 to 3, wherein a reciprocating limiting block is arranged on the longitudinal supporting plate, a set of spring ejector pins and a stopping bolt are respectively arranged on the cover glass sucking station and the pressing sealing station, and the position of the spring ejector pins is higher than that of the stopping bolt, so that the reciprocating limiting block firstly touches the spring ejector pins and then touches the stopping bolt on the station, and the unloading force of the longitudinal supporting plate is slowly reduced.

5. The cover glass sucking and pressing mounting device as claimed in claim 4, wherein the reciprocating stopper is a beam structure vertically fixed on the upper end of the longitudinal support plate, and two ends of the beam structure are respectively provided with a sensing piece.

6. The cover glass suction and pressing coverslipping apparatus of any one of claims 2 to 3, wherein the shuttle mechanism comprises a drive unit and an upright carrier plate, the drive unit being coupled to the longitudinal support plate, the longitudinal support plate being movably disposed on the upright carrier plate, the cover glass suction station and the pressing coverslipping station being disposed at a first region and a second region of the upright carrier plate, respectively, a path of the shuttle of the longitudinal support plate being formed between the first region and the second region of the upright carrier plate.

7. The cover glass sucking and sealing device according to claim 6, wherein the driving unit is a stepping motor, the reciprocating transfer mechanism further comprises a rotating cantilever between the vertical bearing plate and the longitudinal support plate, the rotating cantilever is provided with a hollow slide, the stepping motor is connected with the rotating cantilever through a through hole on the vertical bearing plate, the vertical bearing plate is provided with a roller slide defining a reciprocating transfer path, a roller rod is fixed on the longitudinal support plate, the roller rod is provided with a roller wheel rolling along the roller slide, the roller rod passes through the hollow slide on the rotating cantilever, the stepping motor drives the rotating cantilever and simultaneously drives the longitudinal support plate to move along the roller slide, and the hollow slide ensures the degree of freedom provided by the roller rod to ensure that the longitudinal support plate is moved during the rotation of the rotating cantilever The supporting plate can follow up.

8. The cover glass pick and press slide apparatus of claim 7, wherein the roller slide is a rounded-off U-shaped slide.

9. The cover glass suction and pressing mounting device according to claim 6, wherein the shuttle mechanism further comprises a longitudinal moving guide rail on which the longitudinal support plate is slidably disposed, a lateral slider fixed to the lateral slider, and a lateral moving guide rail slidably disposed on the lateral moving guide rail fixed to the upright carrier plate, thereby keeping the longitudinal support plate in a vertical state at all times during the shuttle.

10. An automatic mounting apparatus for a section of a biological tissue sample, comprising the cover glass sucking and pressing mounting device according to any one of claims 1 to 9.
