This structure requires a large space, resulting in reduced operating efficiency in a limited space, and the suction cup structure also makes a lot of noise. Therefore, an improved technology is urgently needed to solve the above problems existing in the existing technology. Utility Model Content

[0023] See also Figure 1-3 , the utility model provides a technical solution: a push-pull structure suitable for moving slices in a small space, including a push-pull mechanism, a moving platform 4, a pneumatic clamp and a scanning platform 7;

[0024] The push-pull mechanism includes a guide rail 1, a stepper motor 2, a lead screw 3 and a guide block 5. A stepper motor 2 is provided at one end of the guide rail 1. The output shaft of the stepper motor 2 is connected to one end of the lead screw 3 through a coupling. The lead screw 3 is provided on the inner side of the guide rail 1. One end of the mobile platform 4 is connected to the guide block 5 through a bolt. The guide block 5 slides with the guide rail 1. The guide block 5 cooperates with the lead screw 3 through a lead screw pair nut 6. A first limit sensor 14 and a second limit sensor 15 are provided on the side of the guide rail 1 away from the scanning platform 7. A positioning plate 16 is provided on the side of the guide block 5 away from the scanning platform 7. The positioning plate 16 has a positioning groove 17. The positioning plate 16 is provided with a positioning groove 17. The positioning groove 17 cooperates with the first limit sensor 14 and the second limit sensor 15 respectively. The positioning plate 16 cooperates with the first limit sensor 14 and the second limit sensor 15 to limit the stroke of the positioning plate 16, thereby realizing the positioning of the safety position and the clamping position of the pneumatic clamp. A fixing plate 19 is provided at the bottom of the guide rail 1. The fixing plate 19 cooperates with the bolt to realize the fixation of the guide rail 1. The guide rail 1 is also provided with a guide plate 20. The guide block 5 also slides with the guide plate 20. The guide plate 20 realizes the cooperation and guidance of the guide block 5 on the one hand and hides the screw 3 on the other hand to ensure safety.

[0025] The scanning platform 7 has a chute 8 on its upper surface, and a guide groove 9 is provided inside the chute 8. The outer ends of the chute 8 and the guide groove 9 extend to the outside of the scanning platform 7. The scanning platform 7 has a scanning slot 18 at the chute 8. The slice is placed in the scanning slot 18 to achieve slice scanning.

[0026] One side of the pneumatic clamp is connected to the side of the mobile platform 4 away from the guide rail 1. The pneumatic clamp includes a clamp body 10, a movable block 11, a fixed clamp 12 and a movable clamp 13. The clamp body 10 is slidably arranged on the upper surface of the scanning platform 7. A fixed clamp 12 is provided at one end of the bottom of the clamp body 10. A movable block 11 is provided inside the clamp body 10. A movable clamp 13 is provided at one end of the movable block 11 close to the fixed clamp 12. The movable clamp 13 cooperates with the fixed clamp 12. The fixed clamp 12 is slidably arranged in the guide groove. 9, the thickness of the fixed clamping jaw 12 is less than the height of the guide groove 9 to ensure that when the slice is pulled into the slide groove 8, when the slice reaches the scanning area, the end of the slice is against the inner end of the slide groove 8, so that the slice falls off in the slide groove 8, and the slice is just located at the scanning groove 18. A cylinder 21 is provided on the upper surface of the clamping jaw body 10, and the piston rod of the cylinder 21 passes through the top of the clamping jaw body 10 and is connected to the upper surface of the movable block 11. The movable block 11 is driven to rise and fall by the cylinder 21, thereby realizing the lifting and lowering of the movable clamping jaw 13.

[0027] Installation method and operating principle: First, connect the guide block 5 to the guide rail 1. Then, pass the lead screw 3, which is connected to the stepper motor 2 via a coupling, through the lead screw nut 6 of the guide block 5 and install it on the inside of the guide rail 1. Install the stepper motor 2 at one end of the guide rail 1. Next, install the guide plate 20 on the guide rail 1 and engage it with the guide block 5. Connect one end of the movable platform 4 to the guide block 5 with bolts. Then, bolt the positioning plate 16 to the outside of the guide block 5. Install the first limit sensor 14 and the second limit sensor 15 on the outside of the guide rail 1 and engage with the positioning plate 16. Finally, connect the pneumatic gripper to the movable platform 4 and place the fixed jaw 12 of the pneumatic gripper in the guide groove 9 of the scanning platform 7 to complete the installation. During operation, the stepper motor 2 drives the lead screw 3 to rotate. The lead screw 3 engages with the guide block 5 via the lead screw nut 6. The guide block 5 slides along the guide rail 1 and the guide plate 20. During this process, the first limit sensor 14 and the second limit sensor 15 are positioned by the positioning slots 17 of the positioning plate 16. The guide block 5 slides along the guide rail 1 through the cooperation of the lead screw 3 and the lead screw nut 6, thereby driving the pneumatic clamp to move through the mobile platform 4. The fixed clamp 12 of the pneumatic clamp slides along the guide groove 9 and moves to the slice holder. The corresponding slice front end is clamped by the cooperation of the movable clamp 13 and the fixed clamp 12 of the pneumatic clamp. Then the stepper motor 2 reverses, and the mobile platform 4 and the pneumatic clamp are driven to retreat through the cooperation of the lead screw 3 and the lead screw nut 6. The slice moves along the slide groove 8 of the scanning platform 7 until the slice moves to the scanning slot 18. The movable jaw 13 is lifted up, and the end of the slice is against the inner end of the slide 8, just falling into the scanning groove 18. When the slice scanning is completed, the stepping motor 2, the screw 3 and the screw nut 6 cooperate to make the movable platform 4 and the pneumatic clamp push outward until the fixed jaw 12 is inserted under the slice. Then the movable jaw 13 descends and clamps the slice, and at the same time drives the slice back into the slice rack to realize the extraction and replacement of the slice (the slice rack can be raised and lowered by an external lifting mechanism to correspond to different slices, which will not be described here). The utility model has a reasonable structure. It adopts the guide rail 1 and the movable platform 4 to drive the pneumatic clamp to move along the scanning platform 7. Compared with the traditional suction cup or mechanical arm structure, the structure is more compact and suitable for installation in a small space. At the same time, compared with the suction cup structure, there is no air suction sound during use, the noise is smaller, and there is no need to improve or modify the slice rack, which greatly improves the convenience. At the same time, the fixed jaw 12 of the pneumatic clamp slides with the guide groove 9 of the scanning platform 7 to ensure that the pneumatic clamp will not deviate, thereby improving the stability of the pneumatic clamp.

[0028] Anything not described in detail in the present invention is well known to those skilled in the art.

[0029] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
