Description

Technical Field

[0001] The invention relates to the technical field of taking and placing materials of injection molded products, and in particular to a conveying structure and a product grabbing device. Background Art

[0002] Rubber injection molding is a manufacturing process widely used in industrial production to produce various rubber products. In the traditional rubber injection molding process, after injection molding, the mold needs to be opened and the molded product needs to be taken out manually, but this process requires manual labor to overcome a high temperature environment of at least 200°C, which poses a safety hazard.

[0003] With the rapid development of modern industry, workers began to use automatic material handling devices to take out the formed products. Most of the existing automatic material handling devices include a mobile module and a gripper cylinder. The mobile module is used to move the gripper cylinder between the movable mold and the fixed mold, and the gripper cylinder is used to grab the product. After grabbing, the product is moved to the outside of the mold under the action of the mobile module.

[0004] Traditional gripper cylinders are equipped with fluid channel joints on the cylinder body, which are connected to the external air source through hoses. The fluid channel joints themselves and the corresponding hoses will occupy the mold opening space, resulting in an increase in the lifting height of the movable mold when the mold is opened, which is easy to cause safety accidents. In addition, since the hoses are easy to soften and sag in high-temperature working environments, they may even stick to the mold, which is more likely to cause safety accidents.

[0005] Therefore, the above problems need to be solved urgently. Summary of the invention

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] See also Figures 1 to 7 In this embodiment, a conveying structure is proposed, which can convey fluid in a high temperature environment, and by changing the fluid conveying method, it can reduce the space occupied by the hose, thereby reducing the mold opening height of the mold, and can convey the fluid in a high temperature environment.

[0043] Specifically, the conveying structure includes a bracket 1, a fluid channel 13 is opened inside the bracket 1, a fluid outlet 12 connected to the fluid channel 13 is opened on the bracket 1, and the fluid outlet 12 can be sealed and docked with the fluid inlet 110 of the working component to receive the fluid conveyed by the fluid channel 13.

[0044] It is understandable that a fluid channel 13 for conveying fluid is provided inside the bracket 1, and the fluid outlet 12 of the fluid channel 13 is directly connected to the fluid inlet 110 of the working component, thereby saving space for arranging the hose, reducing the mold opening height of the mold, and having aesthetics. In addition, the fluid channel 13 can be prevented from becoming soft and sagging in a high temperature environment, thereby avoiding safety accidents.

[0045] Preferably, the working component is fixed to the bracket 1 by screws, and the fluid inlet 110 of the working component can be docked with the fluid outlet 12. In addition, in order to ensure the sealing of the fluid inlet 110 and the fluid outlet 12 when docking, a sealing ring is provided between the fluid inlet 110 and the fluid outlet 12 to ensure the sealing of the fluid during the transportation process.

[0046] It should be noted that the types of the above-mentioned working components are selected according to actual working conditions and are not specifically limited here.

[0047] In this embodiment, the gripper cylinder 100 is used as an example for explanation. The fluid channel 13 is configured to deliver gas to the gripper cylinder 100 to control the opening and closing of the gripper cylinder 100. It can be understood that the gripper cylinder 100 has a normal open state and a closed state for grasping the product. When grasping the product, the fluid channel 13 delivers gas to the gripper cylinder 100 to move the piston, thereby enabling the gripper cylinder 100 to grasp the product. Subsequently, the gas inside the gripper cylinder 100 is discharged to reset the piston, thereby enabling the gripper cylinder 100 to place the product.

[0048] In addition, the operating component can also be an atomizer 200; the fluid channel 13 includes a gas delivery path 15 and a liquid delivery path 16, the liquid delivery path 16 is configured to deliver liquid to the atomizer 200, and the gas delivery path 15 is configured to deliver gas for atomizing liquid to the atomizer 200.

[0049] When the working parts include both the gripper cylinder 100 and the atomizer 200, the fluid channel 13 is provided with four paths, three of which are used for conveying gas, and the remaining one is used for conveying gas.

[0050] In this embodiment, the bracket 1 is composed of a plurality of profiles 11, the fluid channel 13 is composed of a plurality of branch channels sealed and assembled, and the plurality of branch channels are respectively arranged in a one-to-one correspondence on the plurality of profiles 11. By adjusting the position of the profile 11, the position of the operating component can be adjusted according to different working conditions, so as to improve the applicability of the conveying structure.

[0051] Furthermore, the bracket 1 also includes an adapter 14, which is arranged between the connected profiles 11. The adapter 14 is provided with a transfer channel, and the transfer channel is sealed and connected to multiple branch channels in the profile 11 connected to the adapter 14. Under the action of the adapter 14, the profiles 11 can be docked, and the fluid channels 13 can be spliced ​​after the profiles 11 are spliced. Among them, the adapter 14 is preferably a two-way joint, a three-way joint or a four-way joint, so as to connect different numbers of profiles 11, so as to arrange the positions of the working parts according to different working conditions, thereby further improving the applicability of the conveying structure.

[0052] In this embodiment, under the action of the switching flow channel, one fluid channel 13 can be divided into multiple fluid channels 13 to meet the needs of conveying fluid to multiple working parts.

[0053] Exemplarily, the transfer channel has an inlet and multiple outlets, and the multiple outlets can be sealed and connected to multiple branch channels respectively. When multiple fluid channels 13 are not needed, the outlet of the transfer channel can be selectively sealed by a seal to further improve the applicability of the conveying structure.

[0054] The conveying structure includes a quick-change joint 2, which is arranged on the bracket 1 and is configured to set the bracket 1 on an external mobile structure. The quick-change joint 2 can connect the conveying structure with different mobile structures according to different needs, so as to further improve the applicability of the conveying structure. For example, the mobile structure is a lateral moving module, under the action of which the bracket 1 can be controlled to move laterally to move the bracket 1 to a working position. Of course, the mobile structure can also be a six-axis manipulator, under the action of which the bracket 1 can be controlled to move laterally or flip, etc., to move the bracket 1 to different working positions.

[0055] Specifically, the quick-change connector 2 includes a first connection end 21 and a second connection end 22. The first connection end 21 is arranged on the bracket 1; the second connection end 22 is arranged on the mobile end of the external mobile structure and is adapted to the first connection end 21. When the conveying structure is installed on the mobile structure, the first connection end 21 needs to be fixed on the bracket 1, and the second connection end 22 needs to be fixed on the mobile end of the mobile structure, and then the first connection end 21 and the second connection end 22 are fixed.

[0056] Exemplarily, the quick-change connector 2 is preferably an electrical connector, wherein the first connection end 21 is one of the male end and the female end of the electrical connector, and the second connection end 22 is the other of the male end and the female end.

[0057] In order to facilitate the delivery of gas from an external gas source to the fluid channel 13 inside the bracket 1, in this embodiment, a fluid channel connector 4 connected to the fluid channel 13 is provided on the bracket 1, and the fluid channel connector 4 is connected to the fluid source through a hose. In some working conditions where the bracket 1 needs to rotate, the bracket 1 can rotate under the action of the mobile structure. During the rotation, the hose will rotate with it, causing the hose to be entangled or to be pulled due to the rotation, causing the hose to fall off from the fluid source, thereby causing a safety accident.

[0058] To this end, in this embodiment, a feed pipeline is provided in the first connection end 21 and the second connection end 22, respectively, and the two feed pipelines are sealed and connected, the feed pipeline located at the first connection end 21 is sealed and connected to the fluid channel 13, and the feed pipeline located at the second connection end 22 is sealed and connected to the external gas source. The first connection end 21 and the fluid channel connector 4 are both provided on the bracket 1, so that when the bracket 1 moves, the first control end and the fluid channel connector 4 remain relatively still, thereby preventing the bracket 1 from being entangled during rotation.

[0059] In particular, the fluid channel connector 4 and the first connection end 21 are on the same side of the bracket 1, so the mold opening height of the mold will not be affected. In addition, the distance between the fluid channel connector 4 and the feed pipeline in the first connection end 21 can be reduced, thereby shortening the length of the hose. In addition, when the bracket 1 moves to the working position under the action of the moving structure, the hose is at a position away from the working position, thereby reducing the impact of high temperature on the hose. If the hose still becomes soft and droops, it is also convenient to replace the hose.

[0060] In addition, in order to ensure the strength of the connection between the first connecting end 21 and the bracket 1, an adapter plate 3 is integrally formed on the bracket 1. The area of ​​the adapter plate 3 is larger than the width of the profile 11 and is adapted to the area of ​​the first connecting end 21, thereby increasing the contact area between the first connecting end 21 and the bracket 1.

[0061] Based on the above, a product grabbing device is also proposed in this embodiment, which includes a mobile structure, a clamping cylinder 100 and a conveying structure as described above, the conveying structure can convey gas to the clamping cylinder 100, the bracket 1 is arranged at the mobile end of the mobile structure, and the mobile structure is configured to move the clamping cylinder 100 arranged on the bracket 1 to between the fixed mold and the movable mold, and the clamping cylinder 100 is used to grab the product. Under the action of the conveying structure, the mold opening height can be reduced, and it has aesthetics. In addition, it can also avoid the phenomenon of the control gas path becoming soft and sagging due to the high temperature environment, thereby improving the safety performance.

[0062] Before the product is injected, it is necessary to spray the release agent on the cavity surface of the fixed mold and the movable mold. Usually, it is applied by a spraying device after the product is taken out, or it is applied by a spraying device after the rubber-coated parts are placed in the fixed mold. This process is time-consuming, resulting in reduced production efficiency.

[0063] To this end, in this embodiment, the product grasping device also includes an atomizer 200 for spraying a release agent onto the cavity surfaces of the fixed mold and the movable mold. The atomizer 200 is arranged on one side of the clamping cylinder 100, and along the direction of moving the product out of the fixed mold and the movable mold, the clamping cylinder 100 and the atomizer 200 are moved out of the fixed mold and the movable mold in sequence.

[0064] Specifically, two second output holes for docking the atomizer 200 are provided on the top wall and the bottom wall of the profile 11 of the bracket 1, that is, the atomizer 200 is provided on the top wall and the bottom wall of the profile 11, and the two atomizers 200 are respectively opposite to the cavity surfaces of the fixed mold and the movable mold, so that the release agent can be sprayed on the cavity surfaces of the fixed mold and the movable mold at the same time.

[0065] For example, after the product is captured, the atomizer 200 can spray a mold release agent onto the cavity surface while the mobile structure is moving the product out of the mold, so as to facilitate the subsequent injection molding of the product. Alternatively, before the injection molding, when the part to be coated is placed in the cavity of the fixed mold, the sprayer passes through the cavity before the part to be coated and can spray a mold release agent onto the cavity surface.

[0066] In order to prevent the rubber hose for conveying the release agent and gas to the atomizer 200 from becoming soft and sagging in a high temperature environment, in this embodiment, the fluid channel 13 also includes a conveying gas path 15 and a conveying liquid path 16, and two fluid outlets 12 are provided, and are sealed and connected to the conveying gas path 15 and the conveying liquid path 16 respectively, and the conveying liquid path 16 is configured to convey liquid to the atomizer 200, and the conveying gas path 15 is configured to convey gas for atomizing liquid to the atomizer 200. The conveying gas path 15 and the conveying liquid path 16 are arranged inside the bracket 1, which can further reduce the mold opening height of the mold and have aesthetics. In addition, it can also prevent the conveying gas path 15 and the conveying liquid path 16 from becoming soft and sagging due to the high temperature environment, thereby further improving the safety performance.
