Description

Technical Field

[0001] The utility model belongs to the technical field of material storage and feeding machinery, and specifically relates to a filter screen storage device and a filter screen feeding equipment. Background Art

[0002] Filters are used to filter various fluids such as air and water to intercept impurities and purify the fluid; alternatively, filters can also be used to separate materials based on particle size differences, i.e., to filter particles with smaller sizes (smaller than the mesh size of the filter) and retain particles with larger sizes (larger than the mesh size of the filter).

[0003] As we all know, the filter is a soft structure of a thin mesh layer, which must be attached to a filter frame to be used as a filter assembly. When processing the filter assembly, the filter substrate is usually cut into a preset size of filter in advance, and then several stacked filters are stored in a filter storage bin. When processing is required, the filters are picked out one by one, and the filter frame is processed to form a filter assembly.

[0004] Figure 1 The filter screen 91 is cut to a preset size. Figure 2 A filter assembly 90 is provided in which a filter frame 92 is formed on a filter 91 by injection molding. The shape, size and specific structure of the filter frame can be designed with respective injection molds according to different application scenarios or requirements.

[0005] In traditional technology, workers usually manually take out a filter from the filter storage bin and place it on the fixed mold, then close the movable mold to the fixed mold, and finally perform injection molding of the filter frame; repeat the above process over and over again to produce filter components one by one. Later, in order to realize automated production, the industry developed a special filter picking fixture, and used a robotic arm in conjunction with the filter picking fixture to realize operations such as picking up, transferring, and placing the filter.

[0006] However, the existing filter storage bin is a box-shaped structure with a bottom support, four sides limited and an open top. No matter whether the filter is picked up manually or with a filter picking fixture, multiple filters may be taken out in one operation due to the hooking or electrostatic adsorption between the upper and lower layers of the filter. This will cause abnormal conditions in the subsequent filter assembly processing links, making it difficult to achieve efficient, automated and stable production. Moreover, the filters that are taken out in excess due to hooking may also fall during the transfer process, resulting in adverse effects such as material waste and cluttered workstations.

[0034] Embodiment 1

[0035] Combination Figure 3 , Figure 4 and Figure 5 As shown, the first embodiment provides a filter screen storage device, including a bottom support member 10, a circumferential stopper 20 and a flexible stripping member 30. The circumferential stopper 20 is disposed above the bottom support member 10, and a storage cavity 11 is formed between the bottom support member 10 and the circumferential stopper 20. The storage cavity 11 has an opening at the upper end, and a plurality of filter screens 91 are stacked in the storage cavity 11. The opening at the upper end of the storage cavity 11 is used to centrally store a plurality of filter screens 91 and to take out the filter screens 91 one by one.

[0036] The flexible stripping piece 30 is arranged on the inner side of the opening at the upper end of the storage chamber 11. When picking up the upper filter screen 91, the upper filter screen directly affected by the picking force can be picked up normally, while the lower filter screen connected to the upper filter screen or electrostatically adsorbed is peeled off by the flexible stripping piece 30. This greatly reduces the situation of taking out multiple filters in one operation, ensuring production efficiency while saving raw material expenses and labor costs.

[0037] exist Figure 3 , Figure 4 and Figure 5 In the illustrated embodiment, the circumferential limit member 20 includes a left baffle 21, a right baffle 22, a front baffle 23 and a rear baffle 24 that are discretely arranged circumferentially, and the left baffle 21, the right baffle 22, the front baffle 23 and the rear baffle 24 together form a square storage cavity 11.

[0038] In some other embodiments, the left baffle 21, the front baffle 23, the right baffle 22 and the rear baffle 24 are connected end to end to form a closed baffle continuously arranged in the circumferential direction. It can be understood that the circumferential limiter 20 can be a whole baffle continuously arranged in the circumferential direction, such as a closed circular baffle, a square baffle, or a triangular baffle; the circumferential limiter 20 can also be formed by at least two baffles discretely arranged in the circumferential direction, such as a circular limiter formed by two or three discrete arc-shaped baffles, a square limiter formed by four discrete flat baffles, and so on.

[0039] In this embodiment, the flexible stripping member 30 is a brush, which can reduce the resistance of normal material collection and can also strip the excess filter screen at the lower layer. Of course, the brush can also be replaced by a flexible stripping member with similar functions, such as a flexible rubber protrusion structure, etc.

[0040] In the case where the flexible stripping member 30 is in the form of a brush, the brush handle 31 of the brush is fixedly disposed on the circumferential stopper 20, and the brush head 32 of the brush extends into the material storage cavity 11. Figure 3 , Figure 4 and Figure 5 In the illustrated embodiment, two flexible stripping members 30 are symmetrically provided on the left baffle 21 and the right baffle 22; or, flexible stripping members 30 are provided on the left baffle 21 and the right baffle 22 in a front-to-back manner; or, flexible stripping members 30 are provided on the left baffle 21 and the right baffle 22 in a top-to-bottom manner.

[0041] As an alternative or additional solution, the front baffle 23 and the rear baffle 24 are symmetrically provided with flexible stripping members 30; or, the front baffle 23 and the rear baffle 24 are provided with flexible stripping members 30 offset from left to right; or, the front baffle 23 and the rear baffle 24 are provided with flexible stripping members 30 offset from top to bottom. Here, the number of flexible stripping members 30 provided on each baffle can be selected according to the specific use situation and effect.

[0042] Continue to combine Figure 3 , Figure 4 and Figure 5 As shown, the filter storage device provided in the first embodiment further includes an elastic buffer component 40, which is connected to the bottom of the bottom support member 10 and is used to buffer the picking force when picking up the filter 91 from the storage cavity 11, see Figure 8 Specifically, the elastic buffer assembly 40 includes a base 41, a guide column 42 and an elastic member 43. The guide column 42 is longitudinally arranged above the base 41, and the bottom support member 10 is movably arranged on the guide column 42. The elastic member 43 applies an upward force to the bottom support member 10. More specifically, the elastic member 43 is a compression spring, which is sleeved on the guide column 42, and one end of the compression spring abuts against the base 41, and the other end abuts against the bottom support member 10.

[0043] The working principle and use process of the filter storage device provided in the first embodiment are described as follows:

[0044] (1) Put a plurality of stacked filter screens into the storage cavity 11 of the filter screen storage device from the open opening at the upper end of the storage cavity 11 at one time;

[0045] (2) Manually or by means of a mechanical clamp, the filter screens in the storage chamber 11 are removed layer by layer from the filter storage device through the opening at the upper end of the storage chamber 11;

[0046] During the removal process, due to the connection or electrostatic adsorption between the upper and lower filter screens, the lower filter screen will be taken out at the same time as the upper filter screen is taken out; at this time, the flexible peeling member 30 provided in the present embodiment can apply a peeling force to the filter screen brought out, so that the filter screen brought out from the lower layer falls back into the storage chamber 11, thereby ensuring that the materials are taken out layer by layer one by one.

[0047] Embodiment 2

[0048] See also Figure 5 , Figure 6 and Figure 7 As shown, embodiment 2 provides a filter feeding device, including the filter storage device described in embodiment 1, and also includes a mechanical arm (not shown in the figure) and a filter picking clamp 50, the mechanical arm drives the filter picking clamp to pick up the filter through the open mouth of the filter storage device.

[0049] Specifically, the filter screen picking fixture 50 includes a bracket 51, a pneumatic needle suction cup 52 and a balance block 53. The pneumatic needle suction cup 52 is arranged at one end below the bracket 51, and the balance block 53 is arranged at the other end below the bracket 51, and the lower end of the balance block 53 and the pneumatic needle suction cup 52 are flush; the bracket 51 is connected to the free end of the mechanical arm; the mechanical arm is a mechanical arm that is at least two-dimensionally movable. Among them, the filter screen picking fixture 50 adopts the needle suction cup recorded in the patent document of Chinese Patent Announcement No. CN214003316U or a fixture with similar structure and working principle.

[0050] When working, the filter picking fixture 50 is driven by the mechanical arm to extend into the opening of the filter storage device and contact the filter in the filter storage device. When it reaches the designated position, the picking command signal is triggered, and the pneumatic needle suction cup 52 starts to move and picks up the filter 91. When pressing down, the balance block 53 and the end face of the pneumatic needle suction cup 52 are in the same horizontal plane, which plays a role of moment balance, so that the filter storage device always remains horizontal, ensuring the stability of the suction cup. At the same time, when the filter picking fixture 50 contacts the filter in the filter storage device under the drive of the mechanical arm, the elastic buffer component 40 provided under the bottom support member 10 of the filter storage device can play a certain buffering role (see Figure 8 as shown).

[0051] The filter feeding equipment provided in the above-mentioned embodiment 2 greatly improves the efficiency of taking and feeding the filter from the filter storage device by using the filter storage device described in embodiment 1 in combination with an automated robotic arm and a filter picking fixture.

[0052] The above embodiments are only intended to fully disclose but not limit the present invention. Any replacement of equivalent technical features based on the creative purpose of the present invention without creative labor should be regarded as the scope of disclosure of this application.
