Description

Technical Field

[0001] This utility model relates to a glass slide transport device, and more particularly to a glass slide self-rotating transport device. Background Technology

[0002] Glass slides are transparent media that carry samples and are commonly used experimental tools in medical, biological, and other fields. Slides are typically transported via a transfer container, which is open at one end, through which the slide is inserted. Slide transport involves two actions: flipping and translation. Existing automated transport devices require separate drive components for each of these actions. One drive component rotates the transfer container horizontally and vertically, while the other controls the translation of the slide relative to the container for removal. These two drive components result in a complex transport device structure, large space occupation, and are not conducive to the automated operation of medical devices. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a slide self-rotating transfer device, including a support plate; a transfer box rotatably connected to the upper part of the support plate, wherein a tension spring is installed between the transfer box and the support plate to cause the transfer box to rotate from a horizontal position to a vertical position; a loading groove extending along the length direction is opened on the upper surface of the transfer box, one end of the loading groove being open for accommodating a slide; a push rod assembly, which moves linearly along the slide ejection direction under the drive of a linear servo mechanism, includes a pushing part and a pressing part, wherein the pressing part contacts the edge of the loading groove to push the transfer box to rotate to a horizontal position, and the pushing part is located in the loading groove and contacts the rear end of the slide to push the slide horizontally out along the loading groove.

[0004] Furthermore, a pair of opposing support blocks are fixed to the upper part of the support plate, and a rotating shaft is fixedly connected to the opposing surfaces of the pair of support blocks by a first screw threaded onto the rotating shaft. The transfer box is hinged to the rotating shaft.

[0005] Furthermore, one end of the tension spring is wound around the rotating shaft, and the other end of the tension spring is fixedly connected to the bottom of the transfer box.

[0006] Furthermore, the two sides of the loading groove are provided with inwardly recessed grooves, which extend along the two sides of the loading groove, and the two sides of the glass slide are each engaged in one of the grooves.

[0007] Furthermore, the loading groove is provided with a stepped surface at an angle on the side near the opening.

[0009] Furthermore, the pressure-applying part includes a roller and a fixed seat. The roller contacts the edge of the loading groove, and the roller and the fixed seat are connected to the sheet metal plate by a second screw.

[0010] Furthermore, the rollers are in two sets, arranged back and forth along the horizontal direction of the sheet metal plate.

[0011] Furthermore, the linear servo mechanism includes a guide rail, a driving wheel, a driven wheel, and a transmission belt wound between the driving wheel and the driven wheel.

Detailed Implementation

[0021] like Figures 1 to 3 The slide self-rotating transfer device shown includes a support plate 1 and a transfer box 2 connected to the upper part of the support plate 1, a push rod assembly 3 that applies rotational force to the transfer box 2, and a linear servo mechanism 4 that drives the push rod assembly 3 to move linearly. One end of the transfer box 2 has a rotation center and can rotate relative to the support plate 1 along the rotation center. The support plate 1 is the mounting base of the entire transfer device, supporting the entire transfer device; the transfer box 2 is the bearing component of the slide 5 and is responsible for rotating the slide 5 from the vertical direction to the horizontal direction.

[0022] Specifically, a pair of opposing support blocks 11 are fixed to the upper part of the support plate 1. A rotating shaft 13 is fixedly connected to the opposing surfaces of the pair of support blocks 11 via a first screw 12. This rotating shaft 13 serves as the rotation center of the transfer box 2. A hinge sleeve 21 is fixed to the bottom of the transfer box 2. The hinge sleeve 21 is coaxially connected to the outside of the rotating shaft 13, and a bearing 14 is provided between the hinge sleeve 21 and the rotating shaft 13. When the transfer box 2 is subjected to force, it will rotate around the rotating shaft 13, thereby achieving the rotation of the transfer box 2. A tension spring 15 is connected between the rotating shaft 13 and the transfer box 2. One end of the tension spring 15 is wound around the circumference of the rotating shaft 13, and the other end is fixedly connected to the bottom of the transfer box 2. The tension spring 15 has an elastic force that causes the transfer box 2 to move away from the rotating shaft 13. When an external force is applied along the flipping direction of the transfer box 2, the transfer box 2 flips to a horizontal position, and the tension spring 15 is in a compressed state; when the external force is removed, the transfer box 2 returns to a vertical position due to the deformation recovery of the tension spring 15. Through the application of external force and the deformation recovery of the tension spring 15, the transfer box 2 is driven to switch back and forth between the vertical and horizontal states.

[0023] like Figure 5As shown, the transfer box 2 is a square frame structure. A loading groove 22 extends along the length of the transfer box 2. One end of the loading groove 22 extends out of the end of the transfer box 2. The glass slide 5 is loaded or removed from the opening of the transfer box 2. The loading groove 22 is a U-shaped recessed structure. The two sides of the loading groove 22 are provided with inwardly recessed grooves 23. The grooves 23 extend along the two sides of the loading groove 22. The two sides of the glass slide 5 are each engaged in one groove 23 to ensure the stability of the glass slide 5 during movement.

[0024] Furthermore, the loading groove 22 is provided with a stepped surface 24 at an angle near the opening, forming a progressive guide surface from the outside to the inside. When the glass slide 5 enters or leaves the loading groove 22, it can move along a preset path to avoid deviation or jamming.

[0025] like Figure 5 As shown, the push rod assembly 3 includes a pushing part and a pressing part. The pushing part and the pressing part move synchronously in the horizontal direction under the drive of the linear servo mechanism 4. During the movement, the pressing part applies an external force to the transfer box 2, causing the transfer box 2 to flip to a horizontal position. The pushing part continues to move, driving the glass slide 5 to move horizontally and move out of the transfer box 2.

[0026] The push rod assembly 3 includes a sheet metal plate 31, which serves as a support component for the pushing part and the pressing part. One end of the sheet metal plate 31 is fixedly connected to the output end of the linear servo mechanism 4, and the pushing part is formed by bending the other end of the sheet metal plate 31 to form a push plate 32. The push plate 32 is located in the middle of the loading groove 22. When the transfer box 2 is flipped to a horizontal position, the push plate 32 contacts the rear end of the glass slide 5, and the glass slide 5 moves horizontally along the extension direction of the loading groove 22 until it is removed from the loading box.

[0027] The pressure-applying part includes a roller 33 and a fixed base 34. A connecting hole is coaxially provided on the roller 33 and the fixed base 34, and a second threaded screw 35 passes through the connecting hole, positioning the roller 33 and the fixed base 34 on the side of the sheet metal plate 31. The outer periphery of the roller 33 rolls in contact with the edge of the loading groove 22, reducing frictional loss. During the flipping phase, the contact between the roller 33 and the edge of the loading groove 22 is a line contact or point contact. Compared to the surface contact of sliding friction, this accurately transmits the direction of thrust, dynamically adapts to the flipping trajectory of the transfer box 2, and avoids interference from the lateral component force generated by sliding friction on the transfer box 2. During the translation phase, the roller 33 continuously applies pressure to the transfer box 2 from above, forming a dynamic balance with the deformation recovery of the torsion spring, allowing the transfer box 2 to remain horizontal.

[0028] Furthermore, the rollers 33 are in two sets, arranged horizontally along the sheet metal plate 31 to form two independent contact points. During the translation process, they synchronously press against the edge of the loading groove 22 to ensure the horizontal movement trajectory of the transfer box 2.

[0029] like Figure 4 As shown, in this embodiment, the linear servo mechanism 4 is a synchronous belt drive structure, including a guide rail 41, a driving wheel 43, a driven wheel 44, and a transmission belt 45 wound between the driving wheel 43 and the driven wheel 44. The guide rail 41 is arranged along the translational direction of the glass slide 5, and the sheet metal plate 31 is fixedly connected to the slider 42 of the guide rail 41 by a fixing block 37, and slides with the guide rail 41. The driving wheel 43 and the driven wheel 44 are respectively located at both ends of the stroke of the push rod assembly 3. The driving wheel 43 is connected to the output end of a drive motor 49, and the drive motor 49 provides rotational power. The transmission belt 45 is in contact with the surface of the fixing block 37. A pressure block 36 is provided on the outer side of the fixing block 37. The pressure block 36 presses against the outer side of the transmission belt 45, and the transmission belt 45 is restricted between the fixing block 37 and the pressure block 36. The friction between the transmission belt 45 and the fixing block 37 drives the fixing block 37 to move.

[0030] Furthermore, at least one set of idler pulleys 46 is provided, which are staggered with the driving pulley 43 and the driven pulley 44, and connected to the surface of the support plate 1 by a third locking screw 47. The transmission belt 45 is wound around each set of idler pulleys 46 to change the transmission direction of the transmission belt 45, enabling the driving pulley 43 to drive the driven pulley 44 in a directional manner; at the same time, it can extend the transmission distance and adjust the tension of the transmission belt 45 to ensure efficient transmission. The synchronous belt drive structure adopted in this utility model has the advantage of optimized space. The rotational power of the drive motor 49 is transmitted to the push rod assembly 3 by multiple guide pulleys, realizing flexible adjustment of the power transmission path. Compared with conventional cylinder linear drive, the synchronous belt drive structure is better suited for medical devices, making full use of the space on the support plate 1, with a compact structure and convenient maintenance.

[0031] Furthermore, a photoelectric sensor 48 is fixedly installed on the support plate 1. The photoelectric sensor 48 can detect the stroke position of the push rod assembly 3 on the support plate 1, thereby controlling the timing of the push rod assembly 3 flipping the transfer box 2 and pushing out the glass slide 5.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
