Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-9, an embodiment of the present invention provides a push plate assembly including: the push piece seat 8, the push piece component 3 which is rotatably arranged on the push piece seat 8, and the avoidance component; wherein the slide pushing member 3 can push out the slide 18 in the slide cassette 17; the avoidance assembly enables the blade pushing member 3 to rotate after pushing out the slide 18 to avoid the bottom slide in the cassette 17.
Specifically, the pushing piece member 3 has a pushing piece portion 2 for pushing the slide glass 18 to move, and the number of the pushing piece portions 2 may be one, or may be two or more, which is not limited in this embodiment. During the slide pushing process, the slide pushing portion 2 contacts the slide 18 at the bottom inside the slide cassette 17 and pushes the slide 18 to move, thereby pushing the slide 18 out of the slide cassette 17.
The above-described blade pushing member 3 pushes out the slide 18 inside the slide cassette 17 with its own linear movement, and specifically, the blade pushing base 8 is linearly movable.
In the slide pushing assembly provided by the embodiment of the invention, the slide pushing component 3 is rotatably arranged on the slide pushing seat 8, and the slide pushing component 3 rotates after pushing out the slide 18 to avoid the bottom slide in the slide box 17 through the avoiding component, so that the slide pushing component 3 cannot be contacted with the bottom slide in the slide box 17 in the return process of the slide pushing component 3, the slide 18 is prevented from being worn by the slide pushing component 3 in the return process, the waste amount of the slide 18 is reduced, and the probability of damaging an instrument due to the fact that the slide 18 is worn is reduced; the amount of abraded and crushed slides is also reduced, thereby reducing the time required to process the abraded and crushed slides 18, reducing the amount of work and wasted time.
In the above described slide pusher assembly, the escape assembly enables the slide pusher member 3 to rotate to avoid the bottom slide in the cassette 17 after pushing out the slide 18, it being understood that the slide pusher member 3 rotates to avoid the bottom slide in the cassette 17 before returning to the cassette 17. Then, the blade pushing member 3 can be rotated to avoid the bottom slide inside the cassette 17 before the return and can also be rotated to avoid the bottom slide inside the cassette 17 during the return. To improve reliability and facilitate rotation of the blade pushing member 3, the above-described avoidance assembly preferably enables the blade pushing member 3 to rotate during the return process to avoid the underlying slide in the cassette 17.
The slide pushing member 3 is rotated to avoid the bottom slide in the slide cassette 17, and the slide pushing portion 2 of the slide pushing member 3 is rotatable either toward the side away from the slide cassette 17 or toward the side close to the slide cassette 17. Since the rotation of the blade pushing member 3 requires a rotation space, in order to shorten the stroke of the blade pushing member 13, it is preferable that the blade pushing portion 2 of the blade pushing member 3 is rotated to a side away from the slide cassette 17, that is, the escape assembly can rotate the blade pushing portion 2 of the blade pushing member 3 to a side away from the slide cassette 17 to avoid the bottom slide in the slide cassette 17.
And selecting the specific structure of the avoidance assembly according to actual needs. For example, the blade pushing component 3 is rotatably arranged on the blade pushing seat 8 through a rotating shaft, and the avoiding component can directly drive the rotating shaft to rotate so as to realize the rotation of the blade pushing component 3. However, this requires a large number of parts and has a complicated structure.
In order to simplify the structure, the avoidance assembly comprises: a working part 4 fixed on the blade-pushing component 3, and a driving component 12 arranged at the pushing position of the blade-pushing component 3.
The push-out position of the slide pushing member 3 is a position where the slide pushing member 3 completely pushes out the slide 18 and then moves away from the slide cassette 17. There is a gap between the push-out position and the cassette 17.
Specifically, in the sheet pushing direction of the sheet pushing component 3, the acting part 4 is located at the rear side of the rotation axis of the sheet pushing component 3, the sheet pushing part 2 of the sheet pushing component 3 is located at the front side of the rotation axis of the sheet pushing component 3, and the driving component 12 can push the acting part 4 to move towards the side far away from the sheet pushing seat 8, so that the whole sheet pushing component 3 is driven to rotate, and the sheet pushing part 2 is rotated towards the side far away from the glass sheet box 17; or, in the sheet pushing direction of the sheet pushing component 3, the acting part 4 and the sheet pushing part 2 are both located at the front side of the rotation axis of the sheet pushing component 3, and the driving component 12 can push the acting part 4 to move to the side close to the sheet pushing seat 8, so as to drive the whole sheet pushing component 3 to rotate, and realize that the sheet pushing part 2 rotates to the side far away from the slide box 17.
The driving member 12 can push the acting portion 4 to approach or depart from the blade pushing seat 8, and specifically, the driving member 12 can be a cylinder or a motor or the like which directly applies acting force to the acting portion 4 so as to push the acting portion 4 to approach or depart from the blade pushing seat 8. Thus, the structure is complicated and the cost is high.
For the sake of simplifying the structure, it is preferable that the driving member 12 is moved by the driving plate 14 while the pushing piece member 3 is returned, to push the acting portion 4. Specifically, the driving member 12 has a driving plate 14, and the operating portion 4 can be moved along the driving plate 14 while being in contact with the driving plate 14 during the return of the push piece member 3, and the driving plate 14 has two ends having different heights in the push piece direction. It will be appreciated that the blade member 3 moves linearly toward the initial position during the return process, and the direction of movement of the blade member 3 during the return process is opposite to the blade direction. To ensure the pushing action portion 4, the height of the driving plate 14 is gradually changed in the push piece direction.
If the acting portion 4 is located on the rear side of the rotation axis of the blade pushing member 3 and the blade pushing portion 2 of the blade pushing member 3 is located on the front side of the rotation axis of the blade pushing member 3 in the blade pushing direction of the blade pushing member 3, the height of the front end of the driving plate 14 in the blade pushing direction is smaller than the height of the rear end of the driving plate 14, that is, the vertical distance between the front end of the driving plate 14 and the blade pushing seat 8 is smaller than the vertical distance between the rear end of the driving plate 14 and the blade pushing seat 8. At this time, the height of the driving plate 14 is gradually reduced in the push piece direction.
If the acting portion 4 and the push piece portion 2 are located on the front side of the rotation axis of the push piece member 3 in the push piece direction of the push piece member 3, the height of the front end of the drive plate 14 in the push piece direction is larger than the height of the rear end of the drive plate 14, that is, the vertical distance between the front end of the drive plate 14 and the push piece seat 8 is larger than the vertical distance between the rear end of the drive plate 14 and the push piece seat 8. At this time, the height of the driving plate 14 gradually increases in the push piece direction.
The driving plate 14 may be an arc-shaped plate, a flat plate, or a plate having a shape of the arc-shaped plate, and it is preferable that the driving plate 14 is a flat plate in order to facilitate pushing the operating portion 4. It will be appreciated that the flat plate is inclined relative to the vertical.
In the blade pushing process, the driving plate 14 needs to be retracted from the action part 4 to ensure normal blade pushing. Specifically, the driving member 12 is movably disposed on the supporting base 9 in the vertical direction, and the blade pushing base 8 is movably disposed on the supporting base 9. It will be appreciated that the drive plate 14 slides with the drive member 12 in a vertical direction.
In the sheet pushing process, the driving plate 14 moves along the vertical direction, so that the avoidance action part 4 is realized, and normal sheet pushing is ensured.
The drive plate 14 needs to be reset after the drive plate 14 is retracted from the operation portion 4, that is, the drive member 12 needs to be reset. Specifically, the push plate assembly further includes: a first elastic return assembly capable of returning the driving part 12, and a first limit assembly limiting the driving part 12 from moving in a vertical direction during the driving plate 14 pushes the action part 4.
If the height of the front end of the driving plate 14 in the blade pushing direction is smaller than the height of the rear end of the driving plate 14, in the blade pushing process, after the application part 4 contacts the bottom side of the driving plate 14, the driving plate 14 moves upwards in the vertical direction, that is, the driving part 12 moves upwards in the vertical direction, because the height of the front end of the driving plate 14 is smaller than the height of the rear end of the driving plate 14; when the acting part 4 is separated from the driving plate 14, the driving part 12 moves downwards in the vertical direction under the action of the first elastic resetting component, namely, the driving plate 14 moves downwards in the vertical direction under the action of the first elastic resetting component, so that resetting is realized. During the return of the blade pushing member 3, the acting portion 4 can be in contact with the top side of the driving plate 14, and in order to ensure that the driving plate 14 drives the acting portion 4, the first stopper assembly restricts the driving member 12 from moving downward in the vertical direction, that is, restricts the driving plate 14 from moving downward in the vertical direction.
If the height of the front end of the driving plate 14 is greater than the height of the rear end of the driving plate 14 in the blade pushing direction, after the application part 4 contacts the top side of the driving plate 14 in the blade pushing process, the driving plate 14 moves downward in the vertical direction, that is, the driving part 12 moves downward in the vertical direction, because the height of the front end of the driving plate 14 is greater than the height of the rear end of the driving plate 14; when the acting part 4 is separated from the driving plate 14, the driving part 12 moves upwards in the vertical direction under the action of the first elastic resetting component, namely, the driving plate 14 moves upwards in the vertical direction under the action of the first elastic resetting component, so that resetting is realized. During the return of the blade pushing member 3, the acting portion 4 is in contact with the bottom side of the driving plate 14, and in order to ensure that the driving plate 14 drives the acting portion 4, the first limiting assembly limits the driving member 12 from moving upward in the vertical direction, i.e., limits the driving plate 14 from moving upward in the vertical direction.
In order to facilitate the resetting of the driving part 12, the first elastic resetting assembly comprises a first resetting spring 16 capable of deforming in the vertical direction, and two ends of the first resetting spring 16 are respectively connected with the driving part 12 and the supporting seat 9.
In the above-mentioned pushing assembly, the first elastic restoring assembly may further include: the rotating arm can rotate in the vertical surface, and the first elastic component can enable the rotating arm to reset; wherein the drive member 12 is fixed to the rotary arm. At this time, the movement of the driving part 12 in the vertical direction is achieved by the rotation of the rotating arm.
In the practical application process, the selection is performed according to the requirement, and the specific structure of the first elastic resetting component is not limited in this embodiment.
The specific structure of the first limiting component is also selected according to actual needs. For example, as shown in fig. 6 and 7, the first limiting component includes a first limiting member 15 fixed on the supporting seat 9, the driving member 12 is provided with a limiting portion 19, and the first limiting member 15 abuts against the limiting portion 19 to limit the driving member 12 from moving in the vertical direction in the process of pushing the acting portion 4 by the driving plate.
If the height of the front end of the driving plate 14 in the pushing direction is smaller than the height of the rear end of the driving plate 14 and the first limiting member limits the downward movement of the driving member 12 in the vertical direction, it is preferable that the first limiting member 15 can abut against the bottom side of the limiting portion 19 to limit the downward movement of the driving member 12 in the vertical direction during the pushing of the action portion 4 by the driving plate 14.
If the height of the front end of the driving plate 14 is greater than the height of the rear end of the driving plate 14 in the push-piece direction and the first stopper assembly restricts the driving member 12 from moving upward in the vertical direction, it is preferable that the first stopper 15 be capable of abutting against the top side of the stopper portion 19 to restrict the driving member 12 from moving upward in the vertical direction during the pushing of the action portion 4 by the driving plate 14.
The first limiting member 15 may be a limiting screw, a limiting plate, a limiting protrusion or a limiting post, and the limiting portion 19 may also be a limiting plate or a limiting protrusion, which is not limited in this embodiment.
In the above blade pushing assembly, the driving member 12 may be rotatably disposed on the supporting base 9 in a vertical plane, and the blade pushing base 8 may be movably disposed on the supporting base 9. In this way, the drive plate 14 is also rotatable, and the drive plate 14 is rotated to avoid the action portion 4 in the blade pushing process.
At this time, the above-mentioned push jack assembly still includes: a second elastic return assembly capable of returning the driving part 12, and a second limit assembly limiting the driving part 12 to rotate in a vertical plane during the driving plate 14 pushes the action part 4.
In the practical application process, the limiting direction of the second limiting component to the driving part 12 and the resetting direction of the second elastic resetting component need to be set according to the change of the height of the driving plate 14 in the push sheet direction, which is specifically referred to above and will not be described herein again.
In the above-described push plate assembly, the operation portion 4 can be attached to the drive plate 14 and can move along the drive plate 14, and for the convenience of moving the operation portion 4, the operation portion 4 is preferably a bearing or a roller. Of course, the drive plate 14 may be provided with a guide rail that engages with the operating portion 4, but this embodiment is not limited thereto.
During the return process of the blade pushing component 3, the blade pushing component 3 rotates, and in order to ensure the blade pushing again, the blade pushing component 3 needs to be reset. It will be appreciated that during the return of the blade pushing assembly 3, the blade pushing assembly 3 is repositioned after it has passed the bottom slide in the cassette 17. In order to facilitate the resetting of the blade pushing component 3, the blade pushing component also comprises a third elastic resetting component which can reset the rotated blade pushing component 3.
Specifically, the third elastic return assembly includes a third return spring 7, and two ends of the third return spring 7 are respectively connected to the push sheet component 3 and the push sheet seat 8. In order to install the third return spring 7 conveniently, the pushing piece seat 8 is fixed with a bottom block 11, the pushing piece component 3 is abutted against the top side of the bottom block 11, namely, the pushing piece component 3 is arranged on the top side of the bottom block 11, so that the top end of the pushing piece part 2 of the pushing piece component 3 is parallel to the glass slide in the pushing piece process. Wherein, the two ends of the third return spring 7 are respectively connected with the push piece component 3 and the bottom block 11.
In practical applications, the third elastic resetting component may also be selected to have other structures, and is not limited to the above embodiments.
In the above-mentioned slide pushing assembly, since the slide pushing assembly 3 is rotatably disposed on the slide pushing seat 8, during the slide pushing process, the slide 18 located above the slide 18 moves downward along with the pushing of the slide 18, specifically, when the slide 18 just leaves the slide box 17, the penultimate slide in the slide box 17 falls down and presses on the slide pushing portion 2 of the slide pushing assembly 3, at this time, the slide pushing portion 2 is pressed counterclockwise, that is, the slide pushing portion 2 has a tendency to rotate toward the slide pushing seat 8, in order to ensure the completion of the slide pushing, it is preferable that the above-mentioned slide pushing assembly further includes a third limiting assembly, and during the slide pushing process, the third limiting assembly can limit the rotation of the slide pushing assembly 3 contacting with the slide 18.
The specific structure of the third limiting component is selected according to actual needs, and this embodiment does not limit this.
Specifically, when the driving part 12 pushes the acting part 4 to move during the return process of the blade pushing part 3 through the driving plate 14, the third limiting component includes a third limiting part 6, the third limiting part 6 can cooperate with the acting part 4 to limit the rotation of the blade pushing part 3 contacting with the slide 18 during the blade pushing process, and the third limiting part 6 is a limiting plate.
