DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 7 The embodiment of the present invention provides a flip inkjet device for an industrial robot, comprising a frame 1, wherein two symmetrical supporting legs 2 are fixedly connected to the lower side of the frame 1, a screw rod 3 is rotatably connected inside the frame 1, and a driving member is installed at one end of the screw rod 3; an inkjet assembly is installed on the upper side of the frame 1; a sliding seat 4 is sleeved on the side of the screw rod 3 away from the driving member, and the sliding seat 4 is threadedly connected to the screw rod 3; a component placement assembly is installed on one side of the sliding seat 4.

[0023] The above scheme is adopted: when it is used, when the industrial robot needs to be subjected to inkjet processing, the screw rod 3 is driven to rotate by the driving member, thereby driving the sliding seat 4 and the component placement assembly thereon to move on the screw rod 3. Initially, the sliding seat 4 is close to the driving member. After the driving member is started, the sliding seat 4 will move away from the driving member, and the component placement assembly will be moved to a preset position to install the industrial robot component. After the installation is completed, the driving member drives the screw rod 3 in the reverse direction, so that the sliding seat 4 and the component placement assembly move in the reverse direction, close to the inkjet assembly for inkjet processing, and then away from the inkjet assembly. The industrial robot component after inkjet processing can be taken out. After the inkjet processing of an industrial robot component is completed, the driving member drives the sliding seat 4 again, and the sliding seat 4 drives the component placement assembly to return to the initial installation component position, preparing for the next industrial robot component to be coded, realizing the continuity of the inkjet processing of the industrial robot component, reducing manual intervention, and ensuring the consistency and accuracy of the inkjet coding.

[0024] Furthermore, the inkjet assembly includes a sleeve 5, which is installed on the upper side of the frame 1, and a first cavity 6 is defined in the sleeve 5; an angle rod 7 is threadedly connected to the first cavity 6; and an inkjet head 8 is fixedly connected to the angle rod 7.

[0025] The above scheme is adopted: when it is used, when it is necessary to perform inkjet coding on the parts of the industrial robot, the staff drives the angle rod 7 to rotate the angle rod 7, and uses the threaded connection between the angle rod 7 and the sleeve 5 to make the angle rod 7 realize vertical displacement during the rotation process, that is, gradually descend. At the same time, when the angle rod 7 descends, it will drive the inkjet head 8 to rotate and descend synchronously. When the angle rod 7 descends to the preset position, if it is necessary to further adjust the angle of the inkjet head 8, it only needs to continue to rotate the angle rod 7, and the inkjet head 8 can adjust the required angle according to the needs, thereby improving the adaptability of the inkjet head 8. When the adjustment of the inkjet head 8 is completed, the sliding seat 4 can drive the industrial robot parts to gradually approach the inkjet head 8 to complete the inkjet coding.

[0026] It should be noted that: first, before the inkjet operation, the ink is pre-injected into the inkjet head 8, and the inkjet head 8 directly prints the required characters, patterns or barcodes and other information on the surface of the industrial robot parts by precisely controlling the ejection of ink droplets. Second, a sealing rubber layer can be installed at the bottom end of the angle rod 7. Third, the angle rod 7 can also be rotated by a motor through a transmission mechanism.

[0027] Furthermore, the component placement assembly includes a first mounting seat 9, which is fixedly connected to one side of the sliding seat 4; a first connecting plate 10 is fixedly connected to one side of the first mounting seat 9, and a placement tube 11 is fixedly connected to one side of the first connecting plate 10; a second connecting plate 12 is provided on the lower side of the placement tube 11, and one side of the second connecting plate 12 is fixedly connected to the first connecting plate 10; a first slideway 13 is opened in the second connecting plate 12.

[0028] Furthermore, the component placement assembly also includes a first slider 14 , which is slidably connected to the first slideway 13 ; a placement plate 15 is fixedly connected to the first slider 14 , and the placement plate 15 is aligned with the placement tube 11 .

[0029] Adopting the above scheme: During use, when it is necessary to install the industrial robot parts, the staff will first place the industrial robot parts into the placement tube 11. Since the placement plate 15 is aligned with the placement tube 11, the bottom of the industrial robot parts will naturally contact the upper surface of the placement plate 15 to complete the installation. Subsequently, the sliding seat 4 drives the first mounting seat 9 to move. This action will link the first connecting plate 10 to drive the placement tube 11 to move, and the second connecting plate 12 will also pull the placement plate 15 to move synchronously. When the industrial robot parts move to the position of the inkjet head 8 and the coding area is aligned with the inkjet head 8, the inkjet head 8 can perform coding processing, thereby improving production efficiency and ensuring the accuracy of the coding position.

[0030] It should be noted that a cylindrical industrial robot component can be installed in the placement tube 11 to clamp the industrial robot component.

[0031] Furthermore, a plurality of support rods 16 are installed on the support feet 2, and a straight plate 17 that can be aligned with the moving trajectory of the first connecting plate 10 is installed on the support rods 16, and the straight plate 17 is located on the lower side of the first connecting plate 10; a convex plate 26 is installed on the side of the straight plate 17 away from the sliding seat 4.

[0032] Furthermore, a stopper 18 is fixedly connected to one side of the upper side of the convex plate 26 close to the inkjet head 8; a first airbag 19 capable of contacting the stopper 18 is fixedly connected to the other side of the first connecting plate 10; a second airbag 20 is fixedly connected to the inner wall of the placement tube 11, and a sponge layer is installed on the inner wall of the second airbag 20; the first airbag 19 and the second airbag 20 are connected via a first flexible hose.

[0033] Furthermore, a plurality of top blocks 21 are fixedly connected to one side of the upper side of the straight plate 17 close to the convex plate 26 , and each top block 21 is evenly arranged on the straight plate 17 .

[0034] Furthermore, a connecting frame is fixedly connected to the bottom of the placement plate 15 , and a driving wheel 25 capable of contacting the straight plate 17 is rotatably connected to the outer surface of the connecting frame.

[0035] The above scheme is adopted: when in use, the industrial robot component is installed on the placement tube 11, and the bottom is placed on the placement plate 15, the screw rod 3 drives the sliding seat 4 to move in the opposite direction, and the sliding seat 4 drives the industrial robot component to move synchronously. The driving wheel 25 rotates through the connecting frame and moves on the straight plate 17. As the sliding seat 4 continues to move, the driving wheel 25 will gradually contact multiple top blocks 21. Each time it contacts the top block 21, the placement plate 15 will rise in the first slideway 13 through the first slider 14, pushing the industrial robot component to rise a certain distance relative to the placement tube 11, and when the driving wheel 25 passes the top block 21 and falls into the gap, the placement plate 15 will drive the component to descend. In this way, the industrial robot component is repeatedly lifted and lowered. By installing a sponge layer on the surface of the second airbag 20, when the industrial robot component is repeatedly lifted and lowered and contacts the sponge layer, the dust on the surface of the industrial robot component can be effectively removed, the cleanliness of the component is ensured, and the quality and reliability of the inkjet coding are further improved.

[0036] When the sliding seat 4 drives the placement plate 15 and the industrial robot parts to continuously move in the opposite direction, the driving wheel 25 contacts the convex plate 26 and lifts the placement plate 15, so that the cleaned part of the industrial robot parts is highly aligned with the inkjet head 8. Subsequently, as the sliding seat 4 continues to move, the first airbag 19 contacts the block 18 and is compressed, and the gas inside it enters the second airbag 20 through the first flexible hose, so that the second airbag 20 expands and clamps the industrial robot parts, ensuring the stability of the parts during the coding process, effectively preventing the shaking of the parts during the coding process, and improving the accuracy and efficiency of coding.

[0037] When the coding is completed, the screw 3 drives the sliding seat 4, driving the placement plate 15 and the industrial robot component to move to the initial installation component position, the first airbag 19 no longer contacts the block 18, and the gas in the second airbag 20 will be transmitted back to the first airbag 19, so that the second airbag 20 no longer clamps the industrial robot component. At this time, the industrial robot component can be removed from the placement tube 11, and then the placement plate 15 is driven back to the initial installation component position to install the next industrial robot component.

[0038] It should be noted that: first, the placement plate 15 is double-layered, and the upper layer is a third airbag that can contact the bottom of the industrial robot component, and is connected to the first airbag 19 through a second flexible hose. When the first airbag 19 is compressed, the internal gas will be transported to the third airbag through the second flexible hose, so that the third airbag expands, further raising the height of the industrial robot component, so that the cleaned part is aligned with the inkjet head 8 (the inkjet head 8 can also move downward so that the cleaned part can be aligned with the inkjet head 8), and then the coding process is performed. Second, the second airbag 20 is an annular airbag. Third, when the industrial robot component moves to the initial installation component position, before the driving wheel 25 has not yet contacted the top block 21, the first airbag 19 gradually disengages from the block 18, so that the second airbag 20 no longer clamps the industrial robot component. At this time, the industrial robot component can be removed from the placement plate 15, and the first airbag 19 is an elastic airbag. Fourth, the spacing between the two top blocks 21 allows the driving wheel 25 to fall into the spacing to achieve repeated lifting and lowering of the placement plate 15. Fifth, the top block 21 is made of rubber.

[0039] Furthermore, the driving member includes a first rotating shaft, one end of which is fixedly connected to the screw rod 3, and the other end of the first rotating shaft is provided with a motor 27, and the output end of the motor 27 is fixedly connected to the first rotating shaft.

[0040] With the above solution, when the screw rod 3 needs to be rotated, the output end of the motor 27 drives the first rotating shaft to rotate, and while the first rotating shaft rotates, it drives the screw rod 3 to rotate synchronously.

[0041] Furthermore, a scale line is provided on the upper end of the angle rod 7.

[0042] The above scheme is adopted: when in use, when the angle of the inkjet head 8 is to be adjusted, the angle of the inkjet head 8 can be adjusted by rotating the angle rod 7 to the desired position according to the degree of the scale line thereon.

[0043] Working principle of the present invention: When performing inkjet printing of industrial robot components, the drive is started to cause the screw 3 to rotate, thereby guiding the sliding seat 4 and the component placement assembly carried by it to move along the axis of the screw 3. At first, the sliding seat 4 is close to the drive. Once the drive is working, the sliding seat 4 moves outward and pushes the component placement assembly to the predetermined installation point to facilitate the installation of the industrial robot components. After the installation operation is completed, the drive is reversed so that the screw 3 drives the sliding seat 4 and the component placement assembly to approach the inkjet assembly for inkjet printing. After the inkjet printing is completed, the assembly moves away from the inkjet assembly again to remove the coded industrial robot components. After a round of inkjet printing, the drive is started again, and the sliding seat 4 returns to the initial position with the component placement assembly to prepare for the installation of the next component to be coded, thereby realizing an automated inkjet printing process, reducing the need for manual operation, and ensuring the uniformity and accuracy of the inkjet printing operation.
