Description

Technical Field

[0001] This utility model relates to the field of robotic spraying, specifically to a spraying water and air pipeline system. Background Technology

[0002] Release agent spraying is a crucial step in injection molding, ensuring that molded parts can be smoothly separated from the mold and preventing sticking and damage. Traditional spraying methods typically rely on manual operation, resulting in uneven spraying and low efficiency. With the development of industrial automation, more and more companies are adopting robots for release agent spraying to improve spraying quality and production efficiency. Robotic release agent spraying offers advantages such as uniform spraying, increased efficiency, reduced waste, and improved quality, ensuring consistent spraying results across each batch and enhancing product quality.

[0003] To achieve efficient and precise mold release agent spraying, robots need to be connected to various pipelines and lines, including atomizing gas lines, mold release agent lines, and control gas lines. While these lines ensure the robot can successfully complete the mold release agent spraying task, they also present challenges in pipeline management. Because robots need to rotate in multiple directions during operation, workshops typically allow for a significant amount of pipeline slack to ensure the robot's mobility. However, this leads to repeated friction between the pipelines and equipment, the robot, and the ground during operation, easily causing pipeline wear and even breakage. While fixing the pipelines directly along the outside of the robot reduces friction between the pipelines and the ground, equipment, and the robot, it also affects the robot's mobility, limiting its flexibility and work efficiency. Therefore, there is an urgent need for a pipeline system that can reduce pipeline slack, minimize pipeline pulling, tangling, and wear without affecting the robot's mobility, thereby improving production efficiency and product quality. Utility Model Content

[0004] The present invention aims to provide a spraying water and air pipeline system to reduce pipeline excess and reduce problems of pipeline pulling, tangling and wear without affecting the robot's mobility.

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

[0006] The spraying water and air pipeline system includes a first pipeline, a second pipeline, a third pipeline, and a fourth pipeline, which are sequentially connected. The second, third, and fourth pipelines are arranged along the outer side of the robot. It also includes a one-axis assembly, a two-axis assembly, and a three-axis assembly. The one-axis assembly is connected to the robot's rotating base and includes a first mounting plate with a first rotary joint mounted on it. The first pipeline and the second pipeline are rotatably connected via the first rotary joint. The two-axis assembly includes a rotary mounting seat fixed to the outer side of the robot's upper arm near the lower arm. The second pipeline connects between the first rotary joint and the rotary mounting seat. The three-axis assembly is fixed to the robot's lower arm near the upper arm. The three-axis assembly includes a mounting seat with a connected fixed joint and a second rotary joint mounted on it. The third pipeline connects between the fixed joint and the rotary mounting seat, and the fourth pipeline connects to the second rotary joint.

[0007] Preferably, as an improvement, the one-axis assembly includes an L-shaped base plate, one end of which is fixedly connected to the robot's rotating base, and the other end of which is vertically fixed with two reinforcing support plates, and a first mounting plate is fixed on the two reinforcing support plates.

[0008] Preferably, as an improvement, the first mounting plate has a weight-reduction spare hole.

[0009] Preferably, as an improvement, two reinforcing support plates are disposed on a set of adjacent sides of the base plate and are perpendicularly connected to each other.

[0010] Preferably, as an improvement, the base plate includes an L-shaped first base plate and two strip-shaped second base plates. The two second base plates are connected in parallel to the end of the first base plate away from the first mounting plate. A connecting plate is fixed to the other end of the two second base plates. The connecting plate is fixedly connected to the robot's rotating base. A second pipeline limiting bracket is fixed on the connecting plate. The second pipeline limiting bracket and the first mounting plate are located on both sides of the rotating base, and the second pipeline limiting bracket is on the same side as the two-axis assembly.

[0011] Preferably, as an improvement, the two-axis assembly includes a fixed front plate and a fixed back strip. A rotary mounting base is fixed to the fixed front plate and is detachably fixed to the robot arm via the fixed front plate and the fixed back strip. The rotary mounting base includes a rotating shaft and a rotating base plate fixed to the rotating shaft. A rotating shaft mounting plate is fixed to the fixed front plate, and the rotating shaft is rotatably connected to the rotating shaft mounting plate. Support columns are connected between the four corners of the rotating shaft mounting plate and the fixed front plate. A second mounting plate is vertically fixed to the rotating base plate, and a second pipe connector for communicating with a second pipeline is installed on the second mounting plate.

[0012] Preferably, as an improvement, an L-shaped reinforcing rib is provided between the rotating base plate and the second mounting plate.

[0013] Preferably, as an improvement, a washer ring is fixed to the back of one end of the fixed front plate.

[0014] The principles and beneficial effects of this solution are as follows:

[0015] 1. This solution divides the pipeline into a first pipeline, a second pipeline, a third pipeline, and a fourth pipeline. The second, third, and fourth pipelines are set along the outside of the robot, which effectively reduces the pipeline excess and prevents the pipeline from being dragged on the ground, avoiding friction between the pipeline and the ground, and greatly reducing friction between the pipeline and the robot and other equipment.

[0016] Based on this, the solution connects the first and second pipes via a first rotary joint, and the connection between the third and fourth pipes is connected to the robot via a rotary mounting base. The advantages of this design are: (1) Since the connection between the first and second pipes is rotatably connected, when the robot rotates based on the rotary base, the first pipe and the connection between the first and second pipes can be effectively prevented from twisting, thus effectively protecting the first pipe and the connection, and also preventing the robot's movement from being affected by the pulling and twisting of the first pipe. (2) Since the connection between the third and second pipes is rotatably connected to the robot's upper arm via a rotary mounting base, when the robot's lower arm swings up and down, the rotary mounting base can be rotated through the third pipe, thus preventing the third pipe from being pulled and causing damage to the third pipe and restricting the robot's movement, and also preventing the twisting and damage of the connection between the third and second pipes. (3) If the pipeline is only set along the outside of the robot, in order not to affect the robot's movement, the pipeline still needs to have a certain margin. The design of this application allows the pipeline to be fixed on the robot and the margin of the pipeline can be further reduced, thereby further avoiding pipeline wear.

[0017] In summary, this solution fixes the pipeline along the outside of the robot and allows for movement of the pipeline at key rotational nodes of the robot. This not only reduces the pipeline's excess length and avoids pipeline wear, but also does not restrict the robot's range of motion.

[0018] 2. An L-shaped base plate is adopted for easy installation of the first mounting plate and the second pipeline limiting bracket. The base plate adopts a split structure with the first and second base plates connected together. The second base plate is composed of two strip-shaped plates, which can reduce weight compared to a one-piece plate. In addition, the weight-reduction spare holes on the first mounting plate can further reduce weight and can also be used as spares for installing subsequent pipe fittings.

[0019] 3. The first mounting plate and the base plate are supported by two reinforcing support plates, which make the structure stable. The two reinforcing support plates are set on a set of adjacent sides of the base plate and are perpendicular to each other, which can further improve the support stability.

[0020] 4. The second pipeline limiting bracket is used to support the middle part of the second pipeline, so that it is better fixed on the robot, improving the installation stability of the second pipeline and avoiding the risk of wear caused by the second pipeline hanging.

[0021] 5. The fixed front plate and fixed back strip are used to hold the rotating mount onto the robot from both sides, allowing for easy installation without damaging the robot's structure. Connecting support columns between the fixed front plate and the pivot mounting plate increases the height, providing sufficient installation space for the pivot. Adding L-shaped reinforcing ribs between the rotating base plate and the second mounting plate improves structural strength. Adding spacers to the back of the fixed front plate allows it to be supported on a lower plane on the robot's upper arm, resulting in a more stable installation of the fixed front plate onto the robot.

[0030] The basic implementation examples are as follows: Figure 1 As shown:

[0031] like Figure 1 As shown, the spraying water and air pipeline system includes a first pipeline 1, a second pipeline 2, a third pipeline 3, a fourth pipeline 4, a one-axis assembly 6, a two-axis assembly 7, and a three-axis assembly 8. The first pipeline 1, the second pipeline 2, the third pipeline 3, and the fourth pipeline 4 are connected in sequence, and the second pipeline 2, the third pipeline 3, and the fourth pipeline 4 are arranged along the outside of the robot.

[0032] Combination Figure 2 and Figure 3 As shown, the one-axis assembly 6 includes an L-shaped base plate, comprising an L-shaped first base plate 62 and two strip-shaped second base plates 63. The two second base plates 63 are bolted parallel to one end of the first base plate 62, and a connecting plate 64 is bolted to the other end of the two second base plates 63. The connecting plate 64 is bolted to the rotating base 5 of the robot, and a second pipeline limiting bracket 65 is bolted to the connecting plate 64. Two reinforcing support plates 60 are vertically welded to a set of adjacent sides at the other end of the first base plate 62. The two reinforcing support plates 60 are welded perpendicularly to each other, and a first mounting plate is welded to the top of the two reinforcing support plates 60. Two first rotary joints 61 are mounted on the first mounting plate. Two weight-reduction spare holes 67 are opened on the first mounting plate. The weight-reduction spare holes 67 are used for the installation of other pipe fittings and also serve to reduce weight.

[0033] Combination Figure 4 and Figure 5As shown, the two-axis assembly 7 includes a fixed front plate 71 and a fixed back strip 72. During installation, the fixed front plate 71 and the fixed back strip 72 are placed on both sides of the robot arm 51, and are fixed to the robot arm 51 by tightening the fixed front plate 71 and the fixed back strip 72 with bolts. Two washers 70 are bolted to the back of one end of the fixed front plate 71 to support it on the recessed surface of the robot arm 51, ensuring that the fixed front plate 71 is installed stably. A rotary mounting base is installed on the fixed front plate 71. The rotary mounting base includes a rotating shaft 76 and a rotating base plate 74. The fixed front plate 71 is bolted to the rotating shaft mounting plate 73 by four support columns 75. The rotating shaft 76 is installed on the rotating shaft mounting plate 73. The four support columns 75 can raise the rotating shaft mounting plate 73 to provide sufficient installation space for the rotating shaft 76. One end of the support column 75 is integrally formed with a screw that is directly threaded to the fixed front plate 71. The other end of the support column 75 has a threaded hole. The rotating shaft mounting plate 73 is connected to the support column 75 by bolts. The rotating base plate 74 is bolted to the rotating shaft 76. A second mounting plate 78 is vertically fixed to the rotating base plate 74 by bolts, and a second pipe connector 79 is installed on the second mounting plate 78. An L-shaped reinforcing rib 77 is bolted between the rotating base plate 74 and the second mounting plate 78 to improve the stability of the second mounting plate 78.

[0034] The first pipeline 1, the second pipeline 2, and the third pipeline 3 each include an atomizing gas pipeline 22 and a release agent pipeline 21. The two pipelines of the first pipeline 1 and the second pipeline 2 are rotatably connected through two first rotary joints 61 on the first mounting plate. The other ends of the two pipelines of the second pipeline 2 are fixed on the second mounting plate 78 and are correspondingly connected to the two pipelines of the third pipeline 3. In this embodiment, the second pipeline 2 runs from one side of the rotating base 5 along the outside of the robot to the other side and connects to the rotary mounting seat 80 on the upper arm 51. Therefore, the second pipeline 2 is supported in the middle by the second pipeline limiting bracket 65, which prevents the second pipeline 2 from drooping in the middle and improves the installation stability of the second pipeline 2. It should be noted that the second pipeline 2 has a certain amount of movement in the second pipeline limiting bracket 65 to avoid interfering with the rotation of the rotary mounting seat 80.

[0035] Combination Figure 6As shown, the fourth pipeline 4 includes three pipelines: an atomizing gas pipeline 22, a drying gas pipeline 41, and a mold release agent pipeline 21. The three-axis assembly 8 includes a mounting base 80, on which two fixed connectors 81 and three second rotary connectors 82 are mounted. The two fixed connectors 81 are connected to the atomizing gas pipeline 22 and the mold release agent pipeline 21 of the third pipeline 3, respectively. The atomizing gas pipeline 22 of the third pipeline 3 is split into atomizing gas and drying gas after connection and is connected to the two second rotary connectors 82, respectively. The mold release agent pipeline 21 in the fourth pipeline 4 is connected to another second rotary connector 82 on the mounting base 80. The first mounting plate, the second mounting plate 78, and the mounting base 80 are also equipped with a control gas connector 68 and an electrical control circuit bracket 66. The control gas pipeline and the electrical control circuit are also integrated along the outside of the robot along with the second pipeline 2, the third pipeline 3, and the fourth pipeline 4.

[0036] The working principle of the spraying water and air pipeline system is as follows:

[0037] The pipeline is divided into a first pipeline 1, a second pipeline 2, a third pipeline 3, and a fourth pipeline 4. The second pipeline 2, the third pipeline 3, and the fourth pipeline 4 are set along the outside of the robot, which effectively reduces the pipeline excess and prevents the pipeline from being dragged on the ground, avoiding friction between the pipeline and the ground, and reducing friction between the pipeline and the robot and other equipment.

[0038] When the robot rotates based on the rotating base 5, the first pipe 1 and the second pipe 2 are connected by the first rotary joint 61, which effectively prevents the first pipe 1 and the connection between the first pipe 1 and the second pipe 2 from twisting. This effectively protects the first pipe 1 and the connection, and also prevents the robot's movement from being affected by the pulling or twisting of the first pipe 1. Furthermore, since the connection between the third pipe 3 and the second pipe 2 is rotatably connected to the robot's upper arm 51 through a rotary mounting seat, when the robot's lower arm 52 swings up and down, the rotary mounting seat can be rotated through the third pipe 3, thereby preventing the third pipe 3 from being pulled and damaged, thus avoiding the problem of limiting the robot's movement. It also prevents the connection between the third pipe 3 and the second pipe 2 from twisting and being damaged.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
