[0040] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, in which the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.

[0041] The utility model discloses a material pushing device, please refer to Figures 1 to 7 ,include:

[0042] The push plate 10 pushes the glass slide 61 to slide from the first station 31 to the second station 32 on the sliding platform 30, and the push plate 10 is fixedly connected to a correction switch 40 that moves with the push plate 10;

[0043] The correction mechanism 20 has an extended state away from the glass slide 61 and a retracted state close to the glass slide 61 in the width direction of the glass slide 61. When the correction switch 40 triggers the correction mechanism 20, the correction mechanism 20 is converted from the extended state to the retracted state.

[0044] The push plate 10 pushes the glass slide 61 so that the glass slide 61 slides from the first station 31 to the second station 32 on the sliding platform 30. A correction switch 40 is fixedly connected to the push plate 10, and the correction switch 40 can move with the push plate 10. In the process of the push plate 10 pushing the glass slide 61 to slide from the first station 31 to the second station 32, the correction switch 40 will touch the correction mechanism 20. The correction mechanism 20 has an unfolded state away from the glass slide 61 and a folded state close to the glass slide 61. After the correction switch 40 touches the correction mechanism 20, the correction mechanism 20 changes from the unfolded state to the folded state. Since the correction switch 40 is set on the push plate 10, the operator can control the time for the correction mechanism 20 to calibrate the glass slide 61 according to the position of the correction switch 40 on the push plate 10. In addition, in the folded state, the correction mechanism 20 can correct the position of the glass slide 61 in the width direction of the glass slide 61, thereby avoiding the situation where the sealing position is inaccurate when sealing the glass slide, so that the glass slide 61 is in the correct sealing position. Compared with the prior art, the pusher device disclosed in the present application can achieve the purpose of improving the accuracy of sealing.

[0045] Specifically, the push plate 10 often pushes the glass slide 61 in the length direction. Since the push plate 10 is in contact with the glass slide 61 in the length direction, there is no need to limit the glass slide 61 in the length direction. The position of the push end 11 of the push plate 10 is the position of the glass slide 61. Instead, the glass slide 61 can reach the sealing position by only correcting the glass slide 61 in the width direction of the glass slide 61 through the correction mechanism 20.

[0046] It should be noted that the push plate 10 is fixedly connected with the correction switch 40. Since the correction switch 40 moves with the push plate 10, the operator can select the position where the correction switch 40 is fixedly connected to the push plate 10, and control the position at which the correction switch 40 touches the correction mechanism 20, so that the correction mechanism 20 is converted from the expanded state to the retracted state to realize the correction process. For example, the correction switch 40 can be selected to touch the correction mechanism 20 for correction when the slide glass 61 reaches the position between the first station 31 and the second station 32, or the correction switch 40 can be selected to touch the correction mechanism 20 for correction when the slide glass 61 reaches the second station 32.

[0047] The correction mechanism 20 has an extended state and a retracted state. The process of the correction mechanism 20 changing from the extended state to the retracted state is the correction process of the glass slide 61. The correction process of the glass slide 61 ends when the correction mechanism 20 is in the retracted state. For the glass slide 61 that is in a state where it can be sealed after being pushed out by the push plate 10, the correction mechanism 20 may not come into contact with the glass slide 61 during the correction process, that is, the correction mechanism 20 will only come into contact with the glass slide 61 when the glass slide 61 is in a state where it cannot be sealed after being pushed out by the push plate 10. By setting it in this way, the correction mechanism 20 does not need to correct the glass slide 61 to a position parallel to the pushing direction of the push plate 10, but can also allow the glass slide 61 to have a slight angle of inclination, thereby preventing the glass slide 61 from being broken during the correction process due to the excessive size caused by the manufacturing error of the glass slide 61.

[0048] In addition, the correction mechanism 20 changes state after the correction switch 40 is triggered. A button may be provided on the correction mechanism 20, and the button is connected to a mechanism that drives the correction mechanism 20 to move. After the correction switch 40 triggers the button, the correction mechanism 20 changes from the extended state to the retracted state. After the correction switch 40 is triggered, the correction mechanism 20 may continue to be in the retracted state; or it may be immediately reset from the retracted state to the extended state after correction.

[0049] In some embodiments, please refer to Figures 3 to 7 When the correction switch 40 touches the correction mechanism 20, the correction switch 40 drives the correction mechanism 20 to change from the expanded state to the retracted state.

[0050] Specifically, the correction switch 40 drives the correction mechanism 20. After the push plate 10 drives the correction switch 40 to move, the movement of the correction switch 40 will be transmitted to the correction mechanism 20, that is, the correction switch 40 is used as the power source of the correction mechanism 20, so that the correction mechanism 20 does not need to be driven by other power sources to realize the conversion between the expanded state and the folded state.

[0051] In some specific embodiments, please refer to Figures 3 to 7 The correction switch 40 has a correction bevel 41, which is parallel to the plane where the sliding platform 30 is located, and is not parallel to the movement direction of the push plate 10. The correction mechanism 20 moves on the correction bevel 41 as the push plate 10 moves.

[0052] Among them, the correction switch 40 has a correction bevel 41, the correction bevel 41 is in contact with the correction mechanism 20, and the correction mechanism 20 can move on the correction bevel 41, and at the same time, the correction bevel 41 is parallel to the plane where the sliding platform 30 is located, and the correction bevel 41 is not parallel to the movement direction of the push plate 10, so that when the correction bevel 41 moves, the movement direction of the correction mechanism 20 will change, so that the correction mechanism 20 will not move in the direction of pushing the material of the push plate 10, thereby achieving approaching and moving away from the slide 61 in the width direction, and realizing the unfolding action and the folded state.

[0053] For more specific embodiments, please refer to Figures 3 to 7 The correction mechanism 20 has a bearing 23 , and the bearing 23 is in contact with the correction bevel 41 .

[0054] It should be noted that, in order to make the transition from the unfolded state to the folded state smoother, a bearing 23 is provided on the correction mechanism 20 , and the correction bevel 41 is in contact with the correction mechanism 20 via the bearing 23 .

[0055] In some embodiments, please refer to Figures 1 to 7 The correction mechanism 20 includes a first correction plate 21 and a second correction plate 22, which are arranged opposite to each other and move in a width direction perpendicular to the slide 61, and the correction switch 40 drives and connects the first correction plate 21 and / or the second correction plate 22.

[0056] Specifically, the correction mechanism 20 includes a first correction plate 21 and a second correction plate 22. At least one of the first correction plate 21 and the second correction plate 22 moves toward the opposite side under the drive of the correction switch 40. The correction effect is better when the first correction plate 21 and the second correction plate 22 move relative to each other. The correction switch 40 can selectively connect the first correction plate 21 and the second correction plate 22. The number of correction switches 40 can be two and drive the first correction plate 21 and the second correction plate 22 to be connected respectively. The first correction plate 21 and the second correction plate 22 can also be driven by one correction switch 40.

[0057] In addition, the shapes of the first correction plate 21 and the second correction plate 22 can be the same or different. In this embodiment, the first correction plate 21 has one extension, and the second correction plate 22 has two extensions, and the line connecting the two extensions is parallel to the length direction of the slide 61. The first correction plate 21 and the second correction plate 22 of this shape can effectively avoid the slide 61 from getting stuck during the correction process. Preferably, the height of the extension is equal to the height of the slide 61 placed on the sliding platform 30, so as to obtain a better clamping effect.

[0058] In some specific embodiments, please refer to Figures 3 to 7The correction switch 40 drives the first correction plate 21 and drives the second correction plate 22 through the first correction plate 21 via the transmission component 50 .

[0059] It should be noted that in order to achieve a better correction effect, simplify the pushing device and avoid the use of other driving components, a transmission component 50 is provided. The correction switch 40 drives the first correction plate 21 to be connected. The first correction plate 21 drives the second correction plate 22 to move through the transmission component 50, so that the first correction plates 21 are closer to or farther away from each other.

[0060] For more specific embodiments, please refer to Figures 3 to 7 The transmission component 50 includes a first transmission rod 51, a second transmission rod 52, a first fixing pin 53, a second fixing pin 54, a third fixing pin 55 and a sliding seat 56;

[0061] The first transmission rod 51 has a first spherical connection structure and a first annular structure 511 respectively arranged at both ends, and a first through hole is opened in the middle thereof, the first spherical connection structure is rotatably connected to the first correction plate 21, and the first through hole is sleeved outside the first fixing pin 53 and rotatably connected thereto;

[0062] The second transmission rod 52 has a second spherical connection structure 521 and a second annular structure 522 respectively disposed at both ends, and a second through hole 523 is opened in the middle thereof. The second spherical connection structure 521 is rotatably connected to the second correction plate 22, and the second through hole 523 is sleeved outside the second fixing pin 54 and rotatably connected thereto.

[0063] The first annular structure 511 and the second annular structure 522 are both sleeved outside the third fixing pin 55 and are rotatably connected to the third fixing pin 55. The first fixing pin 53 and the second fixing pin 54 are both fixedly connected to the sliding seat 56. The third fixing pin 55 is slidably connected to the sliding seat 56 in the length direction of the slide 61.

[0064] Specifically, the first correction plate 21 is rotatably connected to one end of the first transmission rod 51 through the first spherical connection structure, the middle part of the first transmission rod 51 is rotatably connected through the first fixing pin 53, the other end of the first transmission rod 51 is rotatably connected to the third fixing pin 55 through the first annular structure 511, and the third fixing pin 55 is also rotatably connected to one end of the second transmission rod 52 through the second annular structure 522, the middle part of the second transmission rod 52 is rotatably connected with the second fixing pin 54, and the other end of the second transmission rod 52 is rotatably connected to the second correction plate 22 through the second spherical connection structure 521.

[0065] Among them, when the correction switch 40 drives the first correction plate 21 to move, the first correction plate 21 will drive the first transmission rod 51 to rotate around the first fixed pin 53, the first transmission rod 51 will drive the third fixed pin 55 to move in the length direction of the slide 61, the third fixed pin 55 will drive the second transmission rod 52 to rotate around the second fixed pin 54, and the second transmission rod 52 will drive the second correction plate 22 to move.

[0066] It should be noted that the first spherical connection structure and the second spherical connection structure 521 can be rotatably connected relative to the first correction plate 21 and the second correction plate 22, respectively. The rotatable connection referred to here refers to a spherical rotational connection. The first annular structure 511 and the second annular structure 522 are both rotatably connected relative to the third fixing pin 55. The rotatable connection referred to here refers to being able to rotate around the third fixing pin 55.

[0067] Preferably, the first annular structure 511 and the second annular structure 522 are both annular with notches, so that they can be more easily disassembled than the third fixing pin 55 .

[0068] Preferably, the sliding seat 56 is connected to a translation block 58, and a slot 59 is provided on the translation block 58. The opening direction of the slot 59 is the same as the width direction of the slide 61. The first correction plate 21 and the second correction plate 22 are both slidably connected to the slot 59. The setting of the translation block 58 can achieve a better correction effect.

[0069] In some more specific embodiments, please refer to Figures 3 to 7 The transmission component 50 also includes a guide rod 57, which is arranged along the length direction of the slide glass 61 and is slidably connected to the sliding seat 56 in the axial direction. The guide rod 57 is fixedly connected to the third fixing pin 55.

[0070] It should be noted that the transmission component 50 further includes a guide rod 57, which is arranged along the length direction of the glass slide 61 and is slidably connected relative to the sliding seat 56. The guide rod 57 is fixedly connected to the third fixing pin 55, and the third fixing pin 55 is slidably connected to the sliding seat 56 in the length direction of the glass slide 61 through the guide rod 57. The guide rod 57 can slide on the sliding seat 56 along its axial direction, which has more stable performance than directly sliding the third fixing pin 55 on the sliding seat 56.

[0071] In some particularly specific embodiments, the transmission component 50 further comprises a spring, which is arranged along the axial direction of the guide rod 57 , with one end of the spring abutting against the sliding seat 56 and the other end abutting against the guide rod 57 .

[0072] The transmission component 50 further includes a spring, the two ends of which are respectively in contact with the sliding seat 56 and the guide rod 57. When the correction switch 40 is not in contact with the correction mechanism 20, the correction mechanism 20 will be restored to the unfolded state, thereby achieving reset for the next correction process. In other embodiments, the reset can also be performed manually.

[0073] Preferably, the spring is sleeved outside the guide rod 57 and loaded in the sliding seat 56. The sliding seat 56 is provided with a stepped through hole, which has coaxial through holes but different diameters, wherein the guide rod 57 is placed in the hole with a smaller diameter, and the spring is placed in the hole with a larger diameter, and a protruding circle 571 for the spring to abut is provided on the guide rod, thereby realizing the installation of the spring, avoiding exposing the spring to the outside, and making the overall structure more stable.

In the length direction of the slide 61, one end of the slide 61 abuts against the film bin 60, and the other end abuts against the limit plate 70.

[0075] Specifically, a film bin 60 is provided at the first work station 31. The film bin 60 is used to load glass slides 61 and can be raised and lowered. In order to solve the problem that multiple glass slides 61 cannot be aligned at the exit of the film bin 60, a limiting plate 70 is provided perpendicular to the glass slide 61. When the glass slide 61 is sealed and pushed back to the film bin 60, the film bin 60 will be raised and lowered so that the next unsealed glass slide 61 can be pushed out, and the glass slide 61 that has been sealed and pushed back to the film bin 60 will be abutted by the film bin 60 and the limiting plate 70, thereby achieving alignment at the exit of the film bin 60.

[0076] In some specific embodiments, please refer to Figure 2 The cross section of one end of the limiting plate 70 is wedge-shaped and is arranged close to the sliding platform 30. The wedge-shaped arrangement will not cause the limiting plate 70 to damage the slide glass 61, and can allow the slide glass 61 to move slowly into the film bin 60.

[0077] In some embodiments, the push plate 10 is driven by a driving mechanism 80. In other embodiments, the push plate 10 may be manually pushed by an operator.

[0078] In some specific embodiments, the driving mechanism 80 includes a motor 81 and a belt 82, and the belt 82 is respectively connected to the motor 81 and the push plate 10. Preferably, the push plate 10 moves through the slide rail 83, so as to obtain a more stable operation.

[0079] In some specific embodiments, please refer to Figures 1 to 4 The push plate 10 is connected with a sensor 84, and the sensor 84 can detect the position reached by the push plate 10, thereby realizing more precise control and adjustment, making the push device more intelligent.

[0080] In some embodiments, please refer to Figures 1 to 4 The push plate 10 has a push-out end 11 and a push-in end 12 . The push-out end 11 is used to push the slide glass 61 from the first station 31 to the second station 32 , while the push-in end 12 is used to push the slide glass 61 from the second station 32 to the first station 31 .
