Description

Technical Field

[0001] The present application relates to the field of mechanical transmission, and in particular to a rack transmission mechanism for a turning device. Background Art

[0002] Cytological preparation and staining are of paramount importance in cytological testing. Only qualified preparation and staining can accurately reflect the pathological status for diagnosis.

[0003] Sedimentation is a commonly used method for preparing cell slides. The method involves first mixing the sample cells, then collecting the cell pellet after two gradient centrifugations. An appropriate amount of buffer is added based on the volume of the cell pellet. After thorough mixing, the diluted cells are transferred using a pipette to a slide containing a sedimentation chamber for natural sedimentation. After sedimentation is complete, the excess liquid in the upper layer is aspirated, and the staining solution is then dripped into the sedimentation chamber for subsequent staining steps.

[0004] The existing preparation and staining process uses vertical pipetting. When aspirating liquid, the liquid level in the sedimentation chamber is high at the side walls and low in the center. If the pipette is too high, it is not easy to aspirate completely; if the pipette is too low, it may touch or aspirate cells. The vertical pipetting method will affect the conventional aspiration and dripping process to a certain extent, reducing the success rate of preparation and staining. Utility Model Content

[0005] Based on this, in order to solve the above technical problems, this patent proposes a rack transmission mechanism for a flipping device. Based on the research and development of a slide preparation and staining machine, this utility model completes the operation of inclined pipetting during the cell slide preparation and staining process.

[0006] The present application provides a rack transmission mechanism for a flipping device, comprising a connecting and fixing base, a flipping motor mounting base provided on the connecting and fixing base, the flipping motor mounting base comprising a left mounting plate, a base, and a right mounting plate connected in sequence, the left mounting plate, the base, and the right mounting plate surrounding a movable space, a slide rail base and a slide rail provided on the base, and a movable rack fixed on the upper portion of the slide rail;

[0007] A flip motor is fixed on the right mounting plate, and the main shaft of the flip motor passes through the right mounting plate. A driving gear is connected to the main shaft, and the driving gear is meshed with a movable rack gear. One end of the movable rack is connected to a ramp push block, and the top of the ramp push block is an inclined surface. The rotation of the flip motor drives the driving gear to make the movable rack and the slide rail move back and forth on the slide rail seat, thereby moving the ramp push block.

[0008] In one embodiment, the slope push block includes a connecting portion and a slope portion, the connecting portion is provided with a connecting socket, and the connecting socket is fixedly connected to the movable rack.

[0009] In one embodiment, a connecting slot is provided on the connecting socket, and one end of the movable rack is engaged in the connecting slot.

[0010] In one embodiment, a connecting hole is provided on the movable rack, and a screw for fixing the connecting bracket is provided in the connecting hole.

[0011] In one embodiment, a photoelectric detection device is provided on the flip motor mounting seat, and the photoelectric detection device is used to detect and control the moving distance of the movable rack.

[0012] In one embodiment, the photoelectric detection device includes a photoelectric detection switch and a blocking trigger, and the photoelectric detection switch is fixed on the left mounting plate.

[0013] In one embodiment, one end of the blocking trigger is fixed on the connecting portion; when the movable rack moves backward, the ramp push block approaches the flip motor mounting seat, and the other end of the blocking trigger is located between the photoelectric detection switches, so that the photoelectric detection switches are triggered, and the flip motor stops rotating through the controller.

[0014] In one embodiment, a receiving groove is formed on the upper surface of the connecting and fixing seat, and the bottom of the flip motor mounting seat is clamped in the receiving groove.

[0017] Technical advantages of this application:

[0018] 1. First, connect the rack transmission mechanism and the corresponding flip assembly to the bottom of the corresponding working area panel. When the slide dyeing machine needs to tilt for aspiration or dripping, the flip motor can be controlled to rotate to lift the working area panel, thereby tilting the liquid level in the sedimentation bin to facilitate aspiration or dripping operations.

[0019] 2. Secondly, by arranging the movable rack and the slide rail to cooperate synchronously, the direct friction of the movable rack is converted into sliding friction between the slide rail and the slide rail seat, which greatly reduces the friction force, thereby reducing the output torque load of the flip motor and improving the overall conveying efficiency;

[0020] 3.

[0032] The present application provides a rack transmission mechanism for a turning device.

[0033] like Figures 1 to 5 As shown, in one embodiment of the present application,

[0034] A rack transmission mechanism for a flipping device includes a connecting and fixing base 1, the upper surface of which is provided with a receiving groove 10, the bottom of the flipping motor mounting base 2 is clamped in the receiving groove 10, and the connecting and fixing base 1 in the rack transmission mechanism is connected and fixed to the corresponding flipping assembly below the corresponding working area panel.

[0035] A flip motor mounting base 2 is provided on the connecting fixing base 1, and the flip motor mounting base 2 includes a left mounting plate 22, a base 21 and a right mounting plate 23 connected in sequence. A flip motor 3 is fixed on the right mounting plate 23. When the film making and dyeing machine needs to be tilted for liquid aspiration or dripping operation, the flip motor 3 can be controlled to rotate to lift the working area panel, thereby tilting the liquid level of the sedimentation bin, which is convenient for liquid aspiration or dripping operation.

[0036] As an embodiment of the present utility model, the main shaft 31 of the flipping motor 3 passes through the right mounting plate 23. The flipping motor 3 can be a servo motor. The main shaft 31 of the servo motor is connected to a driving gear 32. The driving gear 32 and the movable rack 213 are gear-engaged. One end of the movable rack 213 is connected to a ramp push block 4. The top of the ramp push block 4 is an inclined surface. The rotation of the flipping motor 3 drives the driving gear 32, so that the movable rack 213 and the slide rail 212 move back and forth on the slide rail seat 211, thereby moving the ramp push block 4.

[0037] The left mounting plate 22 , the base 21 and the right mounting plate 23 of the flip motor mounting seat 2 form an activity space 200 , and the specific transmission and sliding of the entire device are all within the activity space 200 .

[0038] At the same time, a slide rail seat 211 and a slide rail 212 are set on the base 21. The slide rail seat 211 and the bottom base 21 are also clamped and fixed by screws. The slide rail 212 can slide relatively on the slide rail seat 211, and a movable rack 213 is fixed on the upper part of the slide rail 212; therefore, through the synchronous movement and cooperation of the movable rack 213 and the slide rail 212, the direct friction of the movable rack 231 is converted into the sliding friction between the slide rail 212 and the slide rail seat 211, which greatly reduces the friction force, thereby reducing the output torque load of the flip motor 3. The flip motor only needs a smaller force to drive the entire movable rack 231 to move, thereby improving the overall transportation efficiency.

[0039] The utility model relates to a slope push block 4, which is a specific external implementation mechanism. Since the end of the slope push block is an inclined surface, the tilt angle of the flip mechanism and the liquid level of the sedimentation bin can be adjusted by simply controlling the extended length of the slope push block 4.

[0040] The specific slope push block 4 includes a connecting part 41 and a slope part 42. The connecting part 41 is provided with a connecting socket 43, and the connecting socket 43 is fixedly connected to the movable rack 213. Further, the movable rack 213 is provided with a connecting hole 2130, and the connecting hole 2130 is provided with a screw for fixing it to the connecting socket 43.

[0041] A connecting slot 430 is provided on the connecting seat 43 , and one end of the slope push block 4 is clamped in the connecting slot 430 .

[0042] A photoelectric detection device 6 is provided on the flip motor mounting base 2. The photoelectric detection device 6 is used to detect and control the movable distance of the movable rack 213. Specifically, the photoelectric detection device 6 includes a photoelectric detection switch 61 and a blocking trigger 62. The photoelectric detection switch 61 is fixed on the left mounting plate 22. The photoelectric detection switch 61 is connected to an electric wire and is connected to the controller of the entire device. After the blocking trigger 62 partially blocks the light path between the photoelectric detection switch 61, the photoelectric detection switch 61 sends an electrical signal to the controller, so that the controller controls the flip motor 3 to stop or reverse rotation.

[0043] One end of the blocking trigger 62 is fixed on the connecting portion 41; during the backward retraction movement of the movable rack 213, the slope push block 4 approaches the flip motor mounting seat 2, and the other end of the blocking trigger 62 is between the photoelectric detection switch 61, so that the photoelectric detection switch 61 is triggered, and the flip motor 3 is stopped from rotating through the controller. When the photoelectric detection switch 61 detects the blocking trigger 62, the backward retraction distance of the movable rack 213 has reached the limit, and the liquid level flip angle of the sedimentation bin has become horizontal. The flip motor 3 no longer needs to rotate, and the controller controls the flip motor 3 to stop rotating through the signal transmitted by the photoelectric detection switch 61, thereby achieving the limit effect.

[0044] A limit block 5 is provided at one end of the movable rack 213 away from the ramp push block 4. The upper part of the limit block 5 is connected to the movable rack 213, and the lower part of the limit block 5 is fixedly connected to the slide rail 212. The limit block 5 can move synchronously with the movable rack 213 and the slide rail 212. During the outward movement, it can abut against the slide rail seat 211 at the bottom to prevent the movable rack 213 from extending too long.

[0045] By setting the photoelectric detection device 6 and the limit block 5, the forward and backward movement distance of the movable rack 213 and the slope push block 4 can be limited to prevent the liquid level of the sedimentation bin in the working area from being flipped at too large an angle or directly pipetting horizontally.

[0046] In summary, the rack transmission mechanism is connected to the corresponding flipping assembly and fixed under the corresponding working area panel. When the slide making and staining machine needs to tilt to aspirate or drip liquid, the flipping motor can be controlled to rotate to lift the working area panel, thereby tilting the liquid level in the sedimentation bin, which is convenient for aspirating or dripping liquid; by setting the movable rack and the slide rail to cooperate synchronously, the direct friction of the movable rack is converted into the sliding friction of the slide rail and the slide rail seat, which greatly reduces the friction force, thereby reducing the output torque load of the flipping motor and improving the overall conveying efficiency; by setting the photoelectric detection device and the limit block, the forward and backward moving distance of the movable rack and the slope push block can be limited to prevent the liquid level in the sedimentation bin in the working area from being flipped at too large an angle, or directly pipetting liquid horizontally.

[0047] The various technical features of the above-described embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. In order to make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
