[0002] Automated equipment is gradually being widely used in pathology laboratories to complete the complex tasks of pathology film preparation and reading. The staining, sealing, and scanning steps require the manipulation of large numbers of slides by slide holders. Now, the automated operation of individual devices is possible, and the automatic connection between staining and sealing devices is also possible.

[0003] However, the existing clamping device still has the following technical problems when used:

[0004] The automated connection between the sealing equipment and the scanning equipment has not yet been effectively realized. One of the reasons is that the equipment of different manufacturers has not adopted unified standards, such as the size of the slide rack. The slide rack of the sealing equipment cannot be adapted to the scanning equipment, resulting in poor applicability of the clamping device and inability to meet various models; another reason is that when the slide rack is transferred, the slices are easily fallen off the slide rack, and the control of the movement position needs to be accurate. The current clamping device is not stable enough and the positioning is not accurate enough.

[0005] For this reason, a sheet rack clamping device is now proposed to solve the above-mentioned problems. Utility Model Content

[0021] Example:

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] A film rack clamping device includes a guide rail 1, a slide groove is opened inside the guide rail 1, and a moving mechanism is arranged inside the slide groove. The moving mechanism includes a screw rod 2, which is rotatably arranged inside the slide groove through a bearing. A motor 3 is fixed to the left side wall of the guide rail 1, and the left end of the screw rod 2 is connected and fixed to the output end of the motor 3. The rod wall of the screw rod 2 is threaded with a slider 4, and a limit frame 5 is fixedly connected to the rear side wall of the slider 4. The side wall of the moving mechanism is fixed with a limit frame 5, and a clamping jaw 6 is fixed to the rear end of the upper side wall of the limit frame 5. A film rack sensor 7 is fixed to the right side wall of the clamping jaw 6, and a symmetrical clamping jaw extension block 8 is fixed to the right side wall of the clamping jaw 6. A special-shaped sensing sheet 9 is fixed to the front side wall of the limit frame 5, a first sensor 10 is fixed to the left end of the front side wall of the guide rail 1, and a second sensor 11 is fixed to the right end of the front side wall of the guide rail 1.

[0024] The first sensor 10 and the second sensor 11 are electrically connected to the special-shaped sensing piece 9, the special-shaped sensing piece 9 is electrically connected to the moving mechanism, the clamping jaw 6 is electrically connected to the sheet rack sensor 7, and the special-shaped sensing piece 9 can be detected by the first sensor 10 and the second sensor 11. The first sensor 10 and the second sensor 11 are respectively located at the left limit point and the right limit point. The first sensor 10 and the second sensor 11 can convey different position information through different state combinations.

[0025] The right side wall of the clamp 6 is located between the two clamp extension blocks 8 and a baffle 13 is fixed. When the clamp 6 clamps the film rack, the clamp extension block 8 elastically clamps the film rack to increase friction and clamping force; the baffle 13 can prevent the film rack from falling off; the film rack sensor 7 reads the signal.

[0026] A mounting plate 12 is fixed to the lower side wall of the guide rail 1 , and a mounting adjustment hole is provided on the side wall of the mounting plate 12 .

[0027] The motor 3 is a forward and reverse motor, which can drive the clamping jaw 6 to move left or right.

[0028] The limiting frame 5 is slidably connected to the outer wall of the guide rail 1 .

[0029] The motion state of this device can be divided into four positions: left limit, left working point, right working point, and working area; which correspond to different sensor signal combinations:

[0030] Left operating point: sensor signal: 1 1; that is, a=1 b=1

[0031] At this point, the clamping jaws should be released, that is, the film holder should be released;

[0032] Right operating point: sensor signal: 0 0; that is, a=0 b=0

[0033] At this point, the clamping jaws should be clamped, that is, the film frame is clamped;

[0034] Working area: Sensor signal: 0 1; that is, a=0 b=1

[0035] At this point, the jaws should remain in their current position;

[0036] Left limit: sensor signal: 1 0; that is, a=1 b=0

[0037] At this point, the clamping jaws should be in a loose state;

[0038] As above: When writing the control program, the state of the gripper can be controlled through simple sensor status, and the current device status can also be identified through the sensor status when the device is turned on.

[0039] Working principle:

[0040] During operation, the motor 3 controls the rotation of the screw rod 2, and the screw rod 2 drives the slider 4 threadedly connected to the rod wall to move, and the slider 4 drives the limit frame 5 of the side wall to move. Through the cooperation of the special-shaped sensor 9 and the first sensor 10 and the second sensor 11, the limit detection information is fed back to the motor 3, and the motor 3 controls the rotation of the screw rod 2, thereby controlling the position of the clamping jaw 6, and detecting whether there is a film rack through the special-shaped sensor 7. When the presence of a film rack is detected, the clamping jaw 6 works and cooperates with the clamping jaw extension block 8 and the baffle 13 to clamp and fix the film rack and move it to the corresponding position. The clamping jaw 6 controls the clamping jaw extension block 8 to separate, releases the clamping effect, and causes the film rack to fall.
