Description

Technical Field

[0001] The utility model relates to the field of filter plug production, in particular to a filter mold suction displacement mechanism. Background Art

[0002] The small filter for laboratory use mainly includes a filter lower cover, a filter membrane and a filter upper cover. The filter lower cover and the filter upper cover are both T-shaped cover bodies, and the filter membrane is placed between the filter lower cover and the filter upper cover. The assembly part of the filter is done manually, which is not only inefficient but also prone to secondary pollution; the part is mechanized, which solves the problem of work efficiency and secondary pollution.

[0003] In the current equipment, when the filter membrane passes through the punching station, it will be punched into a filter membrane sample, which will then be sucked by a suction mechanism and translated to the assembly station for assembly. In the assembly station, the filter lower cover needs to be placed, and the filter membrane sample needs to be placed inside the filter lower cover. Since the outer diameter of the filter lower cover is larger than the filter membrane sample, there is a large gap between the stations for placing the filter lower cover. Therefore, when the gap between the stations for punching the filter membrane sample in the punching station is consistent with that of the assembly station, the required filter membrane raw material size is larger, and more waste is generated after punching.

The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0026] Example 1

[0027] like Figure 1-6 As shown, the utility model is a filter mold suction displacement mechanism, which is used to suck the sample from the punching station 100 to the assembly station 200, including: a first Y-axis module 1, a first Z-axis module 2, a variable pitch component 3, and a suction nozzle 4. Specifically:

[0028] The first Y-axis module 1 is mounted on a support frame, such as Figure 5 As shown, the first Y-axis module 1 includes: a first slide rail, a first slider 11 and a first telescopic cylinder 13; there are two first slide rails, which are connected to the support frame along the Y-axis direction, the first slider 11 is slidably connected to the first slide rail, the first slider 11 is connected to the first slide plate 12, the first slide plate 12 is connected to the first Z-axis module 2, the first telescopic cylinder 13 is connected to the support frame, and its telescopic end is connected to the first slide plate 12, and the first telescopic cylinder 13 works to drive the first slide plate 12 and the first Z-axis module 2 to move along the Y-axis direction of the first slide rail.

[0029] The first Z-axis module 2 is connected to the first slide plate 12. Figure 6 As shown, the first Z-axis module 2 includes: a second slide rail, a second slider 21 and a second telescopic cylinder 23; there are two second slide rails, which are connected to the first slide plate 12 along the Z-axis direction, the second slider 21 is slidably connected to the second slide rail, the second slider 21 is connected to the second slide plate 22, the second slide plate 22 is connected to the guide plate 31, the guide plate 31 is connected to the pitch changing component 3, the second telescopic cylinder 23 is connected to the top of the first slide plate 12 through the mounting plate, and the telescopic end thereof is connected to the second slide plate 22; the second telescopic cylinder 23 works to drive the second slide plate 22, the guide plate 31 and the pitch changing component 3 to move along the Z-axis direction of the second slide rail.

[0030] Further, such as Figure 6 As shown, the second slide plate 22 is L-shaped, one side plate of which is connected to the second slider 21, and the other side plate of which is connected to the guide plate 31, and a reinforcing rib plate is also connected between the two side plates; through the modified design, the variable pitch component 3 can be stably supported and connected to ensure the stable movement of the variable pitch component 3.

[0031] The working principle of the first Y-axis module 1 and the first Z-axis module 2 of this embodiment is as follows: the first Y-axis module 1 and the first Z-axis module 2 are used to drive the variable distance component 3 and the suction nozzle 4 to move in the Y-axis and Z-axis directions. When working, the first Z-axis module 2 drives the variable distance component 3 and the suction nozzle 4 to move downward, and sucks the filter membrane sample out from the punching station, and drives the variable distance component 3 and the suction nozzle 4 forward to the assembly work through the first Y-axis module 1, and then drives the variable distance component 3 and the suction nozzle 4 to move downward through the first Z-axis module 2 to place the sample in the filter lower cover of the assembly station.

[0032] like Figure 2-4 As shown, the pitch-changing assembly 3 includes: a guide rail plate 31, a second X-axis module 32, a second Z-axis module 33, a pitch-changing guide plate 34 and a pitch-changing slider 35; Figure 3 As shown in FIG. 4 , the guide plate 31 is a convex structure, the second X-axis module 32 is connected to the horizontal plate of the guide plate 31 , and the second Z-axis module 33 is connected to the vertical plate of the guide plate 31 . Specifically:

[0033] There are four variable pitch sliders 35 in this embodiment, and the second X-axis module 32 includes: a third slide rail and a third slider 321; there are two third slide rails, which are connected to the horizontal plate of the guide rail plate 31 along the X-axis direction, and two third sliders 321 are connected to each of the third slide rails, and the third sliders 321 are respectively connected to a variable pitch slider 35;

[0034] The second Z-axis module 33 includes: a fourth slide rail, a fourth slider 331 and a third telescopic cylinder 332. The fourth slide rail has one and is connected to the vertical plate of the guide rail plate 31 along the Z-axis direction. The fourth slider 331 is slidably connected to the fourth slide rail. The fourth slider 331 is connected to the variable pitch guide plate 34. The third telescopic cylinder 332 is at the top of the vertical plate of the guide rail plate 31. The telescopic end of the third telescopic cylinder 332 is connected to the variable pitch guide plate 34. The variable pitch guide plate 34 is driven to move along the Z-axis on the fourth slide rail through the third telescopic cylinder 332.

[0035] like Figure 2 As shown in or 3, four inclined slide grooves 341 are provided on the variable pitch guide plate 34, and the slide grooves 341 are inclined inwardly from top to bottom; the variable pitch slider 35 includes: a sliding portion 352, and a clamping head 353 connected to one end of the sliding portion 352, the upper surface of the sliding portion 352 is connected to a limiting rod 351, the clamping head 353 is connected to a suction nozzle 4, and the limiting rod 351 slides in the slide groove 341; when the third telescopic cylinder 332 drives the variable pitch guide plate 34 to move downward along the Z axis, under the limitation of the limiting rod 351 and the slide groove 341, the variable pitch slider 35 is displaced along the second X-axis module 32, and the spacing between the variable pitch sliders 35 becomes smaller accordingly; when the third telescopic cylinder 332 drives the variable pitch guide plate 34 to move upward along the Z axis, under the limitation of the limiting rod 351 and the slide groove 341, the variable pitch slider 35 is displaced along the second X-axis module 32, and the spacing between the variable pitch sliders 35 becomes larger accordingly.

[0036] like Figure 7 As shown, A is a conventional design. In order to ensure that the filter membrane sample can be sucked onto the assembly station 200 after punching, the spacing between the punching holes of the filter membrane is consistent with the spacing on the assembly station 200, so there is relatively more waste after the filter membrane is punched; B is the design of this embodiment. Through the variable pitch component 3 of this embodiment, the spacing between the punching holes of the filter membrane is reduced, and the filter sample after punching can still be sucked onto the assembly station 200. Therefore, the suction displacement mechanism of the utility model, by setting the variable pitch component 3, adopts the third telescopic cylinder 332 to drive the variable pitch guide plate 34 to move up and down to change the spacing between each variable pitch slider 35, so as to achieve the purpose of the suction nozzle 4 sucking the sample from the small pitch punching station 100 and moving it to the large pitch assembly station 200, thereby achieving the technical effect of adapting to different pitch stations, reducing the punching size of the filter membrane raw material, improving the utilization rate of the raw material, and greatly reducing the production cost.

[0037] The suction nozzle 4 is connected to a vacuum pump. When the vacuum pump works, the sample is sucked through the suction nozzle 4. When the vacuum pump stops working, the suction nozzle 4 releases the sample.

[0038] The working principle of 1 of this embodiment: when sampling, the third telescopic cylinder 332 drives the variable distance guide plate 34 to move downward along the Z axis. Under the limitation of the limit rod 351 and the slide groove 341, the variable distance slider 35 is displaced along the second X-axis module 32, and the distance between the variable distance sliders 35 becomes smaller accordingly. Each suction nozzle 4 corresponds to each punching station 100; the first Z-axis module 2 drives the variable distance assembly 3 and the suction nozzle 4 to move downward to suck the filter membrane sample out from the punching station. During layout, the third telescopic cylinder 332 drives the variable pitch guide plate 34 to move upward along the Z axis. Under the limit of the limit rod 351 and the slide groove 341, the variable pitch slider 35 is displaced along the second X-axis module 32, and the distance between the variable pitch sliders 35 increases accordingly. Each suction nozzle 4 corresponds to each assembly station 200; the first Y-axis module 1 drives the variable pitch component 3 and the suction nozzle 4 to move forward to the assembly work 200, and then drives the variable pitch component 3 and the suction nozzle 4 to move downward through the first Z-axis module 2 to place the sample in the filter lower cover of the assembly station 200.

[0039] Example 2

[0040] like Figure 2 As shown in or 3, this embodiment 2 is formed on the basis of embodiment 1. The sliding portion 352 of the variable-distance slider 35 is designed to be bent inward from top to bottom, which further reduces the gap after each variable-distance slider 35 is closed, thereby further reducing the size of the filter membrane raw material and improving the utilization rate of the raw material.
