[0027] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0028] like Figure 1 and Figure 4 As shown, a glass slide flipping and conveying mechanism of the present invention comprises a carrying component 1 movable along a conveying direction, a shifting component 2 located at one side of the carrying component 1, and a flipping component 3 located at the end of the carrying component 1. The carrying component 1 is used to carry glass slides and convey the glass slides with the cooperation of an external servo component; the shifting component 2 is used to shift and move the glass slide on the carrying component 1 to the flipping component 3; and the flipping component 3 is used to flip the glass slide.

[0029] like Figure 5 The carrying component 1 includes a carrying tray 11, and a carrying groove 12 for accommodating glass slides is provided on the upper end surface of the carrying tray 11. The carrying groove 12 is located at the incoming material end of the conveying direction and is provided with a return stopper 13. The return stopper 13 prevents the glass slides from sliding due to inertia during the movement of the carrying tray 11. The carrying tray 11 drives the glass slides to move to the side of the flipping component 3 along the conveying direction. After the glass slides are transferred to the flipping component 3, the carrying tray 11 moves toward the incoming material side of the conveying direction.

[0030] A fixed side plate 4 extending along the conveying direction is provided on one side of the bearing assembly 1. The toggle assembly 2 is arranged on the upper end of the fixed side plate 4 through a mounting plate 5, and includes a toggle block 21 located above the bearing assembly 1 and an X-axis translation module 22 driving the toggle block 21 to move along the conveying direction. Figure 6The X-axis translation module 22 includes an X-axis driving motor 221, and a synchronous transmission assembly disposed between the toggle block 21 and the X-axis driving motor 221. Specifically, the synchronous transmission assembly includes a driving pulley 222 and a driven pulley 223 disposed on the mounting plate 5 at intervals along the conveying direction, the driving pulley 222 is connected to the motor shaft of the X-axis driving motor 221, the driving pulley 222 and the driven pulley 223 are connected by a synchronous belt, and the toggle block 21 is connected to the synchronous belt transmission through a synchronous belt connection portion. When the X-axis driving motor 221 is started, the synchronous belt is driven to reciprocate and circulate through the driving pulley 222 to drive the toggle block 21 to reciprocate along the conveying direction.

[0031] Furthermore, the X-axis translation module 22 further includes a first linear guide rail 224 extending in the same direction as the conveying direction, and the toggle block 21 is driven by the X-axis driving motor 221 to move along the conveying direction via the first linear guide rail 224 .

[0032] Furthermore, the toggle block 21 is rotatably connected to a connecting arm 23 via a rotating shaft. In this embodiment, the connecting arm 23 extends perpendicular to the conveying direction, one end of the connecting arm 23 is fixedly connected to the synchronous belt connecting portion, and is slidably connected to the mounting plate 5 via the slide rail of the first linear guide rail 224. The connecting arm 23 is provided with a C-shaped notch 231 opening toward the conveying direction, and the connecting end of the toggle block 21 is located in the C-shaped notch 231. The free end of the toggle block 21 hangs down and exceeds the lower end of the connecting arm 23. The free end that exceeds the limit moves the glass slide from the carrying tray 11 to the flip assembly 3 as the connecting arm 23 moves.

[0033] Furthermore, a first torsion spring 212 is coaxially sleeved on the rotating shaft connected to the toggle block 21, and the first torsion arm of the first torsion spring 212 is resting on the connecting arm 23 as a fixed end, and the second torsion arm of the first torsion spring 212 is a moving end abutting against the toggle side of the toggle block 21 when the toggle block 21 toggle the glass slide.

[0034] Further, such as Figure 7 A rotating abutment surface 211 is provided at the connecting end of the toggle block 21. When the toggle block 21 rotates and is in a vertical state and the free end of the toggle block 21 faces downward, the rotating abutment surface 211 contacts the bottom surface of the C-shaped notch 231 and cooperates with the first torsion spring 212 to ensure that the toggle block 21 is in a vertical position, so that the toggle block 21 is more stable when the slide is moved.

[0035] Furthermore, a notch 14 is provided at the incoming end of the carrying tray 11 in the conveying direction. The notch 14 is arranged on the return stop 13 and docked with the carrying groove 12 to cooperate with the shifting block 21 to shift the glass slide.

[0036] Furthermore, the toggle assembly 2 also includes a travel detection assembly for detecting the travel position of the toggle block 21, including proximity switches 24 located at both ends of the travel of the toggle block 21 and a sensor plate 25 moving with the connecting arm 23. When the connecting arm 23 drives the sensor plate 25 to move to the proximity switch 24, the proximity switch 24 promptly issues an electrical command and accurately controls the stopping of the toggle block 21 through the X-axis drive motor 221.

[0037] like Figure 8 The flip assembly 3 includes a flip bracket 31 and a glass slide box 32 rotatably connected to the flip bracket 31 through a rotating shaft. The rotating shaft is arranged near the feeding port of the glass slide box 32. When no external force is applied, the glass slide box 32 is in a vertical state and the feeding port faces upward. When glass slides need to be fed, the glass slide box 32 is pushed to rotate along the rotating shaft so that the glass slide box 32 changes from a vertical state to a horizontal state. At this time, the feeding port faces the incoming side of the glass slides to ensure that the glass slides can enter the glass slide box 32 smoothly and accurately, thereby realizing efficient and orderly glass slide feeding.

[0038] In this embodiment, the lower end of the carrying component 1 is provided with a flip support plate 6 extending toward the flip component 3. When the carrying component 1 drives the glass slide to gradually approach the flip component 3, the flip support plate 6 pushes the glass slide box 32 to rotate along the rotating shaft until the feed port is docked with the carrying groove 12. At this time, the flip support plate 6 supports the glass slide box 32, and the glass slide box 32 is in a horizontal state. Figure 2 ; When the toggle block 21 completes pushing the glass slide from the carrying slot 12 into the glass slide box 32, the carrying assembly 1 drives the flip support plate 6 to move away from the flip assembly 3, and the glass slide box 32 is reset and in a vertical state after losing support, so as to achieve a 90° flip of the glass slide; at the same time, the toggle block 21 is reset to the incoming end of the toggle assembly 2 under the drive of the X-axis drive motor 221, such as Figure 3 .

[0039] Furthermore, a second torsion spring 321 is sleeved on the rotating shaft connected to the slide box 32. When the slide box 32 is in a horizontal state and a vertical state, two torsion arms of the second torsion spring 321 respectively abut against the lower part and the upper part of the flip bracket 31. The second torsion spring 321 ensures that the slide box 32 is flipped accurately.

[0040] Furthermore, a guide slope 322 is provided at the lower end of the glass slide box 32, and the flip support plate 6 pushes the glass slide box 32 to rotate along the guide slope 322 until the feed port is docked with the supporting groove 12. The guide slope 322 guides the thrust of the flip support plate 6, so that the glass slide box 32 rotates or slides more smoothly, thereby improving the smoothness and accuracy of the operation.

[0041] The glass slide upper material level of the carrying component 1 is located upstream of the toggle component 2. When the carrying tray 11 drives the glass slide to move below the toggle block 21, the toggle block 21 is prevented from being in a vertical state under the torsion of the first torsion spring 212. The toggle block 21 forms an obstacle to the movement of the glass slide along the conveying direction on the side opposite to the toggle side. In this embodiment, a support block 26 is provided at the incoming end of the toggle component 2. When the connecting arm 23 reciprocates along the conveying direction, it passes above the support block 26. When the toggle block 21 reciprocates, the connecting arm 23 passes above the support block 26. When the toggle block 21 is in position and passes over the support block 26, the support block 26 pushes, rotates and lifts the toggle block 21. The kinetic energy provided during the rotation of the toggle block 21 is gradually converted into the elastic potential energy of the first torsion spring 212 and stored in the first torsion spring 212. When the toggle block 21 moves away from the support block 26 along the conveying direction, the elastic potential energy of the first torsion spring 212 is converted into the kinetic energy of the second torsion arm, and pushes the toggle side of the toggle block 21 so that the toggle block 21 is in a vertical state and the free end of the toggle block 21 faces downward.

[0042] Furthermore, a transfer assembly 7 is provided at the end of the fixed side plate 4, including a connecting side plate 8 fixedly arranged at the end of the fixed side plate 4, and a Y-axis translation module 71 for driving the flip bracket 31 to move along the extension direction of the connecting side plate 8. In this embodiment, the fixed side plate 4 and the connecting side plate 8 are in planes perpendicular to each other.

[0043] The Y-axis translation module 71 includes a Y-axis driving motor 711 for driving the flip bracket 31 to move. The Y-axis translation module 71 also drives the glass slide box 32 to reciprocate with the flip bracket 31 through a synchronous transmission component. The synchronous transmission component is not described again here; the Y-axis translation module 71 also includes a second linear guide rail 712 extending in the same direction as the connecting side plate 8. The flip bracket 31 is slidably connected to the connecting side plate 8 through the second linear guide rail 712 under the drive of the Y-axis driving motor 711.

[0044] In this embodiment, the X-axis drive motor 221 adopts a stepper motor to cooperate with the stroke detection component to achieve higher positioning accuracy; the Y-axis drive motor 711 adopts a DC reduction motor to operate the slide box 32 and the slide more smoothly.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
