Description

Technical Field

[0001] This utility model relates to the field of dustproof device technology, and in particular to a dustproof device for a fully pneumatically powered robotic arm. Background Technology

[0002] A fully pneumatic assisted manipulator is an automated device that uses compressed air as a power source and pneumatic components to move the manipulator to complete tasks such as material handling and assembly. The compressed air is provided by an air compressor, which compresses the air and then delivers it to the pneumatic components of the manipulator through pipelines.

[0003] In existing technologies, it is not convenient to filter the transported gas, which is not conducive to dust prevention. Dust entering the pneumatic components will affect normal use. Therefore, we have proposed a dust prevention device for a fully pneumatic assisted manipulator to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of inconvenient gas filtration and dust prevention in a fully pneumatically powered manipulator, and to propose a dust prevention device for this device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The dustproof device for the fully pneumatic assisted robotic arm includes:

[0007] Air compressor;

[0008] Mounting bracket, installed at the air inlet of the air compressor;

[0009] U-shaped air passage, located on the mounting base;

[0010] The connection port is located on one side of the mounting base, and the U-shaped air passage is connected to the air inlet of the air compressor through the connection port;

[0011] Two mounting boxes are hinged to the other side of the mounting base. Each mounting box contains a filter screen, which covers the two openings of the U-shaped air passage. Each mounting box has an air inlet on one side.

[0012] The switching plate is slidably installed inside the U-shaped airway;

[0013] A rectangular groove is located on the inner wall of the U-shaped airway;

[0014] A rectangular block is slidably installed in a rectangular groove, and the switching plate is fixedly connected to the rectangular block.

[0015] A vertical moving mechanism, mounted on a mounting base, is used to raise and lower the rectangular block;

[0016] A limiting mechanism, located on the mounting base, is used to limit a mounting box.

[0017] Preferably, the vertical moving mechanism includes a screw, which is rotatably installed in a rectangular groove, and the screw is threadedly connected to the rectangular block. A second bevel gear is fixedly sleeved on the outer side of the screw.

[0018] Preferably, the mounting base has a rectangular cavity, a crossbar is rotatably mounted in the rectangular cavity, one end of the crossbar extends into the rectangular groove and is fixedly mounted with a first bevel gear, the first bevel gear meshing with a second bevel gear.

[0019] Preferably, the limiting mechanism includes a rotating rod rotatably mounted on one side of the mounting base, a limiting block fixedly mounted on the outer side of the rotating rod, and one side of the limiting block contacting one side of the corresponding mounting box.

[0020] Preferably, one end of the rotating rod extends into the rectangular cavity and is fixedly mounted with a driving gear, which meshes with a driven gear, and the driven gear is fixedly sleeved on the outside of the crossbar.

[0021] Preferably, a rotating block is fixedly installed at the other end of the rotating rod, and a locking bolt is threaded onto the rotating block. Two threaded grooves are opened on one side of the mounting base, and one end of the locking bolt is threadedly connected to the corresponding threaded groove.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] The U-shaped air passage is divided into upper and lower air passages. The switching plate closes the upper part of the U-shaped air passage, so that gas can only enter from the lower air passage. The outside gas passes through the lower air inlet, then through the lower filter screen before entering the lower air passage. Then it enters the air compressor through the connection port. The air compressor outlet is connected to the pipeline of the fully pneumatic assisted manipulator to deliver compressed gas into the fully pneumatic assisted manipulator. Through the filter screen, dust and impurities can be filtered out.

[0024] When the filter needs to be replaced, install the new filter into the upper mounting box, then turn the locking bolt to disengage it from the upper threaded groove. Next, turn the rotating block, which drives the rotating rod to rotate, causing the rotating rod to move the limiting block from one side of the lower mounting box to the other side of the upper mounting box, thus releasing the restriction on the lower mounting box and fixing the upper mounting box. Then, turn the locking bolt to connect with the threaded groove below to fix the rotating block.

[0025] When the rotating rod rotates, the rectangular block drives the switching plate downward, closing the lower air passage and opening the upper air passage. At this time, filtration can continue through the upper filter screen. Then, the lower mounting box is flipped open, and the filter screen inside can be removed for cleaning. By switching between the two air passages, the gas filtration work can be interrupted and the machine can be stopped when the filter screen that needs to be cleaned is removed.

[0026] This invention uses a filter screen to filter gas, thus preventing dust. The filter screen is easy to disassemble and clean. When disassembling the filter screen that needs cleaning, the gas filtration process can be interrupted without stopping the machine, thus avoiding disruption to normal operation.

[0032] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments. Example

[0033] Reference Figures 1-4 The dustproof device for the fully pneumatic assisted robotic arm includes:

[0034] Air compressor 1;

[0035] Mounting bracket 2 is installed at the air inlet of air compressor 1;

[0036] U-shaped airway 4 is provided on mounting base 2;

[0037] Connection port 3 is located on one side of mounting base 2, and U-shaped air passage 4 is connected to the air inlet of air compressor 1 through connection port 3;

[0038] Two mounting boxes 5 are hinged to the other side of the mounting base 2. Each mounting box 5 contains a filter screen 6, which covers the two openings of the U-shaped air passage 4. Each mounting box 5 has an air inlet 7 on one side.

[0039] The switching plate 8 is slidably installed inside the U-shaped airway 4;

[0040] A rectangular groove 9 is located on the inner wall of the U-shaped air passage 4;

[0041] A rectangular block 10 is slidably installed in a rectangular groove 9, and a switching plate 8 is fixedly connected to the rectangular block 10.

[0042] A vertical moving mechanism, mounted on the mounting base 2, is used to raise and lower the rectangular block 10;

[0043] A limiting mechanism, located on the mounting base 2, is used to limit a mounting box 5.

[0044] In this embodiment, the vertical moving mechanism includes a screw 11, which is rotatably installed in a rectangular groove 9. The screw 11 is threadedly connected to a rectangular block 10, and a second bevel gear 16 is fixedly sleeved on the outer side of the screw 11.

[0045] In this embodiment, a rectangular cavity 13 is provided on the mounting base 2, and a crossbar 14 is rotatably installed in the rectangular cavity 13. One end of the crossbar 14 extends into the rectangular groove 9 and is fixedly installed with a first bevel gear 15. The first bevel gear 15 meshes with a second bevel gear 16.

[0046] In this embodiment, the limiting mechanism includes a rotating rod 12 rotatably mounted on one side of the mounting base 2, and a limiting block 20 is fixedly mounted on the outer side of the rotating rod 12. One side of the limiting block 20 is in contact with one side of the corresponding mounting box 5.

[0047] In this embodiment, one end of the rotating rod 12 extends into the rectangular cavity 13 and is fixedly mounted with a driving gear 17. A driven gear 18 meshes with the driving gear 17, and the driven gear 18 is fixedly sleeved on the outside of the crossbar 14.

[0048] In this embodiment, a rotating block 19 is fixedly installed on the other end of the rotating rod 12. A locking bolt 21 is threaded on the rotating block 19. Two threaded grooves 22 are opened on one side of the mounting base 2. One end of the locking bolt 21 is threadedly connected to the corresponding threaded groove 22.

[0049] In this embodiment, when used, as follows: Figure 1 As shown, the U-shaped air passage 4 is divided into upper and lower air passages. The switching plate 8 closes the upper part of the U-shaped air passage 4, allowing gas to enter only from the lower air passage. External gas passes through the lower air inlet 7, then through the lower filter screen 6 before entering the lower air passage. It then enters the air compressor through the connection port 3. The air compressor's outlet is connected to the piping of the fully pneumatic assisted manipulator, used to deliver compressed gas into the fully pneumatic assisted manipulator. The filter screen 6 filters out dust and impurities. When the filter screen 6 needs replacement, a new filter screen 6 is installed in the upper mounting box 5. Then, the locking bolt 21 is rotated to disengage from the upper threaded groove 22. Subsequently, the rotating block 19 is rotated, causing the rotating rod 12 to rotate, which in turn causes the limiting block 20 to rotate from one side of the lower mounting box 5 to the other side of the upper mounting box 5, releasing the restriction on the lower mounting box 5. 5 is fixed, and then the locking bolt 21 is rotated to connect with the threaded groove 22 below, fixing the rotating block 19. At the same time, when the rotating rod 12 rotates, it will drive the driving gear 17 to rotate, the driving gear 17 will drive the driven gear 18 to rotate, the driven gear 18 will drive the crossbar 14 to rotate, the crossbar 14 will drive the first bevel gear 15 to rotate, the first bevel gear 15 will drive the second bevel gear 16 to rotate, and the second bevel gear 16 will drive the screw 11 to rotate, causing the rectangular block 10 threadedly connected to the screw 11 to move downward. The rectangular block 10 will drive the switching plate 8 to move downward, closing the lower air passage and opening the upper air passage. At this time, filtration can continue through the upper filter screen 6. Then, the lower mounting box 5 is flipped open, and the filter screen 6 inside can be removed for cleaning. By switching between the two air passages, the gas filtration work can be interrupted and the machine can be stopped when the filter screen 6 that needs to be cleaned is removed. Example

[0050] The difference from Example 1 is as follows:

[0051] Each of the two mounting boxes 5 has a handle fixedly installed on one side, which makes it easy to flip the mounting box 5.

[0052] The rest is the same as in Example 1.

[0053] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
