[0031] When robot spraying is used in the coating industry, the spray gun is installed on the robot wrist. The existing technology is to assemble the spray gun on the robot wrist through an adapter and connect the corresponding feed pipeline to the adapter. However, the adapter cannot accommodate and hide the feed pipeline, and the feed pipeline is directly exposed to the spraying operation environment, which makes the feed pipeline prone to bending, corrosion and other damages, affecting the structural stability of the spray robot.

[0032] The main purpose of the utility model is to provide a spray gun connection seat 100 for installing and connecting a spray gun 200 with a mechanical arm 300 of a spray robot, aiming to solve the technical problem of how to improve the structural stability of a feed pipeline of the spray robot.

[0033] For example, Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the connection state of a spray gun connection base 100 and a spray gun 200 according to an embodiment of the utility model; Figure 2 This is a schematic diagram of the spray gun connection base 100 and the spray gun 200 in a separated state according to an embodiment of the utility model; Figure 3 It is a cross-sectional view of an embodiment of the spray gun connecting seat 100 of the present invention.

[0034] The spray gun connecting seat 100 proposed in the utility model includes: a receiving portion 10, the receiving portion 10 is provided with a receiving cavity 11, and the receiving cavity 11 is used to receive a feed pipeline; a spray gun adapter 20, the spray gun adapter 20 is connected to one end of the receiving portion 10, the spray gun adapter 20 is used for installation of a spray gun 200, the spray gun adapter 20 is provided with a fluid inlet 21, a fluid outlet 22, and a flow channel 23 connecting the fluid inlet 21 with the fluid outlet 22; the fluid inlet 21 is used for communication with the feed pipeline, and the fluid outlet 22 is used for communication with the feed port of the spray gun 200; a connecting piece 30, the connecting piece 30 is connected to one end of the receiving portion 10 away from the spray gun adapter 20, and the connecting piece 30 is used for connection with a mechanical arm 300 of a spraying robot.

[0035] In this embodiment, the receiving portion 10 is provided in a shell shape, which may be a rectangular shell shape, a spherical shell shape, or other special-shaped shell shapes, which are not limited here. The spray gun adapter 20 may directly adopt an existing adapter, or may be independently designed and produced, as long as it can be installed on the spray gun 200. The connecting member 30 may be a flange, or may be a connecting member 30 in other forms such as a sleeve, which are not limited here.

[0036] When the spray gun connection seat 100 is used, the connector 30 is connected to the mechanical arm 300 of the spray robot, and the spray gun 200 is installed on the spray gun adapter 20, so that the mechanical arm 300 can drive the spray gun 200 to move to different positions to spray different positions of the spray object. After the connector 30 is connected to the mechanical arm 300 of the spray robot, the feed pipeline extending from the mechanical arm 300 can enter the receiving chamber 11 and then communicate with the fluid inlet 21 on the spray gun adapter 20. The feed pipeline is mainly used to transport paint for spraying to the spray gun 200. In addition, fluid substances such as spray, gas or flushing liquid can also be transported to the spray gun 200 to achieve different treatment methods for the spray object. After the feed pipeline is connected to the fluid inlet 21, the fluid can flow from the feed pipeline to the flow channel 23, and then flow into the spray gun 200 through the fluid outlet 22 for use by the spray gun 200.

[0037] The accommodating cavity 11 can centrally accommodate the feed pipeline, thereby hiding and protecting the feed pipeline, preventing the feed pipeline from being easily damaged due to bending or corrosion, thereby improving the structural stability of the feed pipeline; in addition, the accommodating cavity 11 can also prevent the feed pipeline from being scattered and exposed, so as to improve the appearance consistency of the spray robot.

[0038] The fluid inlet 21 and the receiving chamber 11 may be spaced apart or close to each other. After the feed pipe is inserted into the receiving chamber 11, the end of the feed pipe may extend out of the receiving chamber 11 and then communicate with the fluid inlet 21, or may communicate with the fluid inlet 21 in the receiving chamber 11.

[0039] Specifically, Figure 3 As shown, both ends of the accommodating portion 10 are respectively provided with openings connected to the accommodating cavity 11, and the spray gun adapter 20 has a first side wall 24 and a second side wall 25, the first side wall 24 covers the opening at one end of the accommodating cavity 11, and the second side wall 25 is used for installing the spray gun 200, the fluid inlet 21 is opened in the first side wall 24, and the fluid outlet 22 is opened in the second side wall 25.

[0040] The first side wall 24 and the second side wall 25 can be arranged opposite to each other, and the flow passage 23 passes through the first side wall 24 and the second side wall 25. The first side wall 24 of the spray gun adapter 20 is covered on one end opening of the receiving cavity 11, so that the connection between the spray gun adapter 20 and the receiving portion 10 can be more compact, so as to improve the compactness of the structure of the spray gun connection seat 100; and the end of the supply pipeline does not need to extend out of the receiving cavity 11 when communicating with the fluid inlet 21, so as to further avoid the supply pipeline from being exposed, so as to improve the hiding and protection effect of the supply pipeline.

[0041] The feeding pipeline may pass through the connecting piece 30 or may pass through the connecting piece 30 when extending from the robot arm 300 into the receiving chamber 11 .

[0042] In practical applications, such as Figure 3 As shown, the connector 30 is covered at the other end opening of the receiving chamber 11, and the connector 30 is provided with a pipe opening 31, and the pipe opening 31 is connected to the receiving chamber 11, so that the feed pipeline can enter the receiving chamber 11. The connector 30 is annular, for example, it can be a flange, and the receiving part 10 and the mechanical arm 300 are respectively connected to the opposite sides of the connector 30, so that the connection area with the mechanical arm 300 can be increased and the connection stability can be improved; the annular connector 30 can also fully cover the end opening of the receiving chamber 11, reducing the influence of the external environment on the feed pipeline in the receiving chamber 11. In this way, the feed pipeline can be further prevented from being exposed, so as to further improve the hiding and protection effect of the feed pipeline.

[0043] The receiving chamber 11 can be kept closed or opened, which is not limited here.

[0044] For example, Figure 4 As shown, Figure 4 The disassembly diagram of an embodiment of the spray gun connection seat 100 of the utility model is shown in FIG. The receiving portion 10 includes a connecting plate 12 and a cover 13 detachably connected to the connecting plate 12 , the connecting plate 12 and the cover 13 are arranged to form the receiving cavity 11 , and one of the connecting plate 12 and the cover 13 is connected to the spray gun adapter 20 and the connector 30 .

[0045] The cover shell 13 may include three shell plates connected in a U shape. When the feed pipeline in the accommodating cavity 11 needs to be inspected and maintained, the cover shell 13 and the connecting plate 12 can be detached, so that the feed pipeline can be exposed to facilitate maintenance personnel to inspect and maintain the feed pipeline, thereby improving the convenience of inspecting the feed pipeline.

[0046] One of the cover 13 and the connecting plate 12 is connected to the spray gun adapter 20 and the connecting piece 30, and the other is not connected to the spray gun adapter 20 and the connecting piece 30, so that when the receiving chamber 11 is opened, it is only necessary to detach the cover 13 and the connecting plate 12, and no additional disassembly operation is required, thereby further simplifying the disassembly and repair process of the feed pipeline. For example, the cover 13 may be connected to the spray gun adapter 20 and the connecting piece 30, and the connecting plate 12 may be not connected to the spray gun adapter 20 and the connecting piece 30, so that when the receiving chamber 11 needs to be opened, it is only necessary to detach the connecting plate 12 from the cover 13, and the cover 13 may still remain connected to the spray gun adapter 20 and the connecting piece 30.

[0047] Specifically, Figure 4 As shown, one end of the connecting plate 12 is connected to the first side wall 24, and the other end is connected to the connecting piece 30. It can be understood that when the receiving chamber 11 needs to be opened, the cover 13 is detached from the connecting plate 12, the spray gun adapter 20 and the connecting piece 30, and the connecting plate 12, the spray gun adapter 20 and the connecting piece 30 are still connected; in this way, compared with the method of detaching the connecting plate 12 alone, the detachment of the cover 13 alone can make the receiving chamber 11 more fully open, so as to facilitate maintenance personnel to inspect the feed pipeline.

[0048] The connection method of the connecting plate 12 and the spray gun adapter 20 can be adhesive fixing, or integrally formed, or other methods. For example, a connecting protrusion can be convexly provided on the connecting plate 12, and the spray gun adapter 20 can be provided with a connecting hole, and the connecting protrusion is fixedly matched with the connecting hole to achieve a fixed connection between the connecting plate 12 and the spray gun adapter 20. The connection method of the connecting plate 12 and the connecting member 30 can be adhesive fixing, or integrally formed, and can also refer to the connection method of the connecting plate 12 and the spray gun adapter 20, which will not be repeated here.

[0049] For example, Figure 4 As shown, the cover 13 is provided with a gripping notch 131 at the top corner of the side close to the connecting plate 12. The gripping notch 131 is used for maintenance personnel to release the connection between the cover 13 and the connecting plate 12, and then pick up the cover 13 from the gripping notch 131 with a tool or a finger, thereby further simplifying the removal process of the cover 13 to improve the removal efficiency. The gripping notch 131 can be provided at the four top corners of the side close to the connecting plate 12 of the cover 13, so that it is convenient for maintenance personnel to pick up the cover 13 from multiple positions, thereby further improving the removal efficiency of the cover 13.

[0050] The connection between the cover 13 and the connecting plate 12 can be fixed by snapping or by fasteners, which is not limited here, as long as the connection is detachable.

[0051] Specifically, Figure 4 As shown, the side of the cover 13 close to the connecting plate 12 is provided with a through hole 132, and the connecting plate 12 is provided with a fixing hole 121, and the fixing hole 121 is connected to the through hole 132 by a fastener. The fixing hole 121 can be a screw hole, and the fastener can be a screw. The fastener and the fixing hole 121 are threadedly matched, which can simplify the disassembly and assembly process of the fastener and the fixing hole 121. The cover 13 has through holes 132 on both sides close to the connecting plate 12, and the number of through holes 132 on each side is at least two. The number and position of the fixing holes 121 on the connecting plate 12 correspond to the through holes 132, and each fixing hole 121 is connected to each through hole 132 by a fastener, so that the connection position between the cover 13 and the connecting plate 12 can be increased to improve the connection stability.

[0052] A pipe joint may be installed at the fluid inlet 21 to connect the feed pipeline, so as to simplify the connection between the feed pipeline and the fluid inlet 21. The pipe joint may be a fixed joint or a rotatable joint.

[0053] For example, Figure 3 and Figure 4 As shown, the number of the fluid inlets 21 is at least two, and the number of the fluid outlets 22 and the flow channels 23 corresponds to the number of the fluid inlets 21; at least two of the fluid inlets 21 include a paint inlet, and the spray gun connection seat 100 also includes a rotary joint 40, which is installed at the paint inlet for connecting the feed pipeline.

[0054] The rotary joint 40 allows the feed pipeline and the spray gun 200 adapter to rotate relative to each other, so that when the robot arm 300 moves and causes the feed pipeline to rotate, the connection state between the feed pipeline and the fluid inlet 21 is not affected, thereby improving the working stability of the spray gun connector 100.

[0055] Specifically, Figure 5 As shown, Figure 5 The cross-sectional schematic diagram of an embodiment of the adapter in the utility model. The flow passage 23 includes an inflow section 231 and an outflow section 232 connected to each other, the inflow section 231 is connected to the fluid inlet 21, the outflow section 232 is connected to the fluid outlet 22, and the angle between the inflow section 231 and the outflow section 232 is set to be greater than 90° and less than 180°, for example, it can be 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°, etc.

[0056] In the prior art, the angle between the inflow section 231 and the outflow section 232 is usually a right angle, which causes the paint and other fluids to experience a right-angle turn in the flow channel 23 before flowing into the spray gun 200, affecting the flow speed and flow smoothness of the fluid, and easily leading to unstable continuous supply of paint and uneven spraying. In this embodiment, the angle between the inflow section 231 and the outflow section 232 is set to be greater than 90° and less than 180°, which can reduce the flow of paint and other fluids in the flow channel 23 to be more unobstructed, thereby ensuring the stability of continuous supply of paint and uniform spraying.

[0057] For example, Figure 6 As shown, Figure 6 The schematic diagram of the structure of an embodiment of the spraying robot of the utility model. The utility model also proposes a spraying robot, which includes a mechanical arm 300, a spray gun 200 and a spray gun connecting seat 100. The specific structure of the spray gun connecting seat 100 refers to the above embodiment. Since the present spraying robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the mechanical arm 300 is connected to the connecting piece 30 of the spray gun connecting seat 100, and the spray gun 200 is detachably mounted on the spray gun adapter 20 of the spray gun connecting seat 100.

[0058] In the technical solution of the spray gun connection seat 100 of the utility model, the spray gun adapter 20 and the connector 30 are respectively connected to the two ends of the receiving part 10, the spray gun adapter 20 can be installed for the spray gun 200, and the connector 30 can be connected to the mechanical arm 300 of the spray robot, so that the spray gun 200 can be assembled on the spray robot. The flow passage 23 on the spray gun adapter 20 can be connected to the feed pipeline, so that the feed pipeline can provide fluids such as paint to the spray gun 200. The receiving cavity 11 set in the receiving part 10 can centrally receive the feed pipeline, so as to hide and protect the feed pipeline, avoid the feed pipeline from being easily damaged due to bending or corrosion, etc., so as to improve the structural stability of the feed pipeline; in addition, the receiving cavity 11 can also prevent the feed pipeline from being scattered and exposed, so as to improve the appearance consistency of the spray robot.

[0059] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
