Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of die casting, and particularly relates to a spraying robot and a die casting machine. BACKGROUND
[0002] A die casting machine using molten aluminum as a forming raw material needs to spray a mold surface with a mold release agent after each time the mold is opened to form a mold release layer on the mold surface, so that a metal casting can be more smoothly taken out of the mold. Each mold release agent needs to form an effective mold release layer at a certain temperature range, but since the mold shape is complex, the mold internal cooling cannot make the mold surface temperature consistent. Therefore, the spraying also needs to play a role in cooling and balancing the mold temperature. In order to unify the mold surface of different temperatures to the temperature range, we need to divide the nozzles on the spray head into multiple groups, and the opening time and flow of each group are different according to the needs of the mold. The spray head usually needs three kinds of pipelines (respectively for compressed air, mold release agent and control gas) to realize spraying.
[0003] However, the more the number of nozzles, the more the number of pipelines, and the larger the action range of the robot, which will cause friction between the pipelines. The pipelines are prone to slight or large area damage. After the pipeline is damaged, it will seriously affect the production qualification rate, machine operation rate and product delivery of the customer, increase the maintenance cost and time, and air leakage will increase the operation cost of the machine.

Therefore, the statements "in some embodiments", "in some embodiments", "in other some embodiments", "in other some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiments, but mean "one or more but not all embodiments", unless otherwise specifically emphasized.

[0049] The first aspect of the embodiments of the present application provides a spraying robot, such as Figure 1 and Figure 2 As shown, the spraying robot includes a platform 10, a mechanical arm 20, a spray head 30, a control assembly 40 and a centralized pipeline 50;
[0050] The platform 10 is used to carry a mold;
[0051] The mechanical arm 20 has a fixed end 21 and a moving end 22, the fixed end 21 is rotatably arranged on the platform 10, and the moving end 22 is located above the platform 10 or the moving end 22 is located in the mold;
[0052] The spray head 30 is connected with the moving end 22, and a plurality of nozzles are arranged on the spray head 30, which are used for spraying operation on the mold located on the platform 10;
[0053] The control assembly 40 is used to control the spray head 30 and the nozzles to perform spraying operation;
[0054] One end of the centralized pipeline 50 is connected with the control assembly 40, the other end of the centralized pipeline 50 is connected with the spray head 30 and the nozzles, and the middle part of the centralized pipeline 50 is arranged on the platform 10 and the mechanical arm 20;
[0055] Among them, the centralized pipeline 50 includes a release agent pipe, a spraying gas pipe and a plurality of control gas pipes.
[0056] The spraying robot provided by the embodiments of the present application can realize centralized pipeline of the release agent pipe, the spraying gas pipe and the control gas pipe through the centralized pipeline 50, which greatly reduces the number of pipelines, and the whole pipeline is more simple and beautiful, and is not easy to cause friction loss.
[0057] In application, the platform is used to support the mechanical arm of the spraying robot and provide maintenance space for the equipment in addition to being used to carry the mold. The platform can be a die casting machine template or a separately arranged support platform.
[0058] In application, the release agent pipe, the spraying gas pipe and the control gas pipe are enclosed together by the enclosing member to prevent friction between the connected pipes and effectively reduce the number of pipes and improve the neatness and beauty of the spraying robot. The enclosing member includes but is not limited to a tie, a bandage or a hollow pipe. The release agent pipe, the spraying gas pipe and the control gas pipe are arranged in the hollow pipe, and the inner wall of the hollow pipe is further provided with a buffer member including but not limited to plastic and foam. In this way, various pipes can be concentrated and the friction between the pipes can be effectively reduced to prevent damage to the pipes.
[0059] In application, due to too many pipes, the adjacent pipes can only be bundled together to prevent disorder during the movement of the robot. However, the adjacent pipes are bundled together, but the robot has a large action range, which can cause friction between the pipes and easily damage the pipes. Due to the complexity of the robot movement, the pipes can only adopt soft pipes with small bending radii to prevent serious twisting and generate a large reaction force on the robot during movement. However, such flexible pipes will be drooping and will rub against the robot during complex movement of the robot, which can easily cause damage to the pipes.
[0060] In some embodiments, as shown in Figure 1 and Figure 2 , the concentrated pipes 50 are arranged in sections, wherein the concentrated pipes 50 connecting the control assembly 40 and the platform 10 are the first section 51, the concentrated pipes 50 connecting the platform 10 and the mechanical arm 20 are the second section 52, and the concentrated pipes 50 connecting the mechanical arm 20 and the spray head 30 are the third section 53. The first section 51 is rotationally connected to the second section 52, and the second section 52 is rotationally connected to the third section 53. The concentrated pipes 50 are arranged in sections and rotationally connected between each section, which is beneficial to avoid excessive bending of the concentrated pipes 50 or wear between the pipes caused by the mechanical arm 20 during rotation, and facilitates the rotation of the mechanical arm 20.
[0061] In application, the existing multi-path 3 / 4" gas pipe is changed to a concentrated pipe mode (1 root 2" or other required caliber), which greatly reduces the number of hoses and moves the grouping of the pipes to the rear of the robot arm for control through a φ6 small gas pipe. In this way, the pipes can be simplified to 1 release agent pipe + 1 spraying gas pipe + several control gas pipes, which are simple and beautiful.
[0062] In some embodiments, as shown in Figure 1 and Figure 2As shown, the mechanical arm 20 is a multi-axis mechanical arm 20, and a rotating pipe joint 60 is arranged at a joint of the multi-axis mechanical arm 20. A plurality of concentrated pipes 50 arranged along the mechanical arm 20 are connected to the rotating pipe joint 60.
[0063] Specifically, the mechanical arm 20 is a three-axis mechanical arm 20. The three-axis mechanical arm is composed of three mutually perpendicular linear axes, each axis responsible for movement in one direction. Through servo motors and precision guide rail systems, the three-axis mechanical arm can achieve high-precision positioning and repeat positioning in X, Y, Z three directions, ensuring the consistency and accuracy of each operation. The three-axis mechanical arm can be easily integrated into existing production lines, working with other equipment (such as die casting machines, conveyors, sensors, etc.), forming an efficient automated production system. The three-axis mechanical arm in die casting application, release agent spraying: the three-axis mechanical arm can accurately control the position and angle of the spray head 30, ensuring that the release agent evenly covers the mold surface, improving the release effect and the quality of the castings. Through the injection of cooling medium (such as air or water), the three-axis mechanical arm can help regulate the mold temperature, keeping it within the optimal working range.
[0064] In some embodiments, as shown in Figure 3 The rotating pipe joint 60 includes a support plate 61, a pipe bracket 62, and a rotating direct head 63. The support plate 61 is arranged on the mechanical arm 20. In other embodiments, the support plate 61 can also be arranged on the platform 10.
[0065] The pipe bracket 62 is connected to the support plate 61, and the pipe bracket 62 is used to support the concentrated pipe 50. The concentrated pipe 50 is fixed to improve its connection stability.
[0066] The rotating direct head 63 is arranged on the support plate 61 and is used to connect with the concentrated pipe 50. By connecting the concentrated pipe 50 through the rotating direct head 63, the rotation of each concentrated pipe 50 is realized, so as to adapt to the complex movement of the mechanical arm 20 and avoid friction and damage between the pipes.
[0067] In some embodiments, as shown in Figure 4 The rotating pipe joint 60 further includes a mounting seat 64, the mounting seat 64 is connected with the support plate 61, and the rotating direct head 63 is arranged on the mounting seat 64, which is conducive to improving the installation stability of the rotating direct head 63, so as to improve the stability of the concentrated pipe 50.
[0068] In application, when the spraying robot sprays, the mechanical arm 20 will move, causing the pipe to have a twisted position. The rotating pipe joint 60 is used to connect and manage the concentrated pipe, ensuring the service life of the pipe, and the mechanical arm will not be affected by the reaction force from the pipe to generate an alarm signal.
[0069] In some embodiments, as shown in Figure 4As shown, the control assembly 40 comprises a control valve plate 41 and a control electric box 42,
[0070] The first pipeline 400 is arranged on the control valve plate 41 for filtering and stabilizing the compressed air, and the second pipeline is arranged on the control valve plate 41 for filtering and stabilizing the release agent. In this way, the pipeline layout is neat and reasonable, and the pipelines do not cross each other, avoiding friction damage.
[0071] The control electric box 42 is arranged on the control valve plate 41, and the control electric box 42 is internally provided with a control valve (not shown in the figure), which controls the nozzle to spray. Because the number of control valves is large, if directly exposed to the outside, water can easily enter to cause short circuit, so the control valve is arranged in the control electric box 42 to avoid water entering and short circuit.
[0072] In some embodiments, as shown in Figure 5 The second pipeline comprises a first interface 411 for inputting clean water, a second interface 412 for inputting release agent, and a third interface 413 for discharging sewage, and the first interface 411, the second interface 412 and the third interface 413 are arranged side by side and spaced apart. In this way, the pipeline layout is neat and reasonable and does not affect each other.
[0073] In some embodiments, as shown in Figure 1 The platform 10 is provided with a surrounding frame 11 on the side, and the surrounding frame 11 is used to provide physical protection for the mechanical arm 20. In this way, the objects outside the platform 10 can be prevented from colliding with the mechanical arm 20 or the pipeline and the casting, effectively providing physical protection. In some embodiments, as shown in Figure 6 The platform 10 is further provided with a protective cover 12 for protecting the centralized pipeline 50. Further physical protection is provided for the pipeline to prevent damage.
[0074] In some embodiments, the outer layer of the release agent pipe and the spray gas pipe is provided with a steel wire layer, and the bending radius of the release agent pipe and the spray gas pipe is greater than that of the control gas pipe. In application, the release agent pipe and the spray gas pipe are rubber pipes, and the control gas pipe is a nylon pipe. The release agent pipe and the spray gas pipe use a pipe with a steel wire layer and a larger bending radius. No matter what the posture of the mechanical arm is, the pipeline will not be pulled down and rubbed against the mechanical arm. The steel wire layer ensures the durability of the pipeline. There is no contact between the pipelines, that is, no friction. The wear resistance of the nylon pipe is excellent and it will not be worn out.
[0075] The application also provides a die casting machine, as shown in Figure 1 The head plate 70 is provided with an interface, and is connected to the spraying robot described above through the interface.
[0076] The die casting machine cooperates with the spraying robot, after the die casting machine completes one time of casting and opens the mold, the spraying robot immediately intervenes to execute the spraying and cooling tasks, and a high-efficiency die casting production line is constituted.
[0077] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described or recorded in a certain embodiment can be referred to the related description of other embodiments.
[0078] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the foregoing embodiments of the present application are described in detail, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the embodiments of the present application.
