[0022] The following is combined with Figure 1-4 The embodiments of the present utility model are described in detail.

[0023] Example 1

[0024] The utility model relates to a multi-color color-changing valve box, which is located beside a spraying robot and connected to a spraying pipe of the spraying robot, and is used to provide paint for the spraying robot. The utility model is characterized in that it comprises a box body 1, wherein the box body 1 has a top wall, a bottom wall and a side wall, wherein the box body 1 is provided with a first through hole 11 penetrating the top wall, and the box body 1 is provided with a first opening 12 penetrating the bottom wall, and a projection of the first through hole 11 in the axial direction is located within the first opening 12.

[0025] Specifically, as the application of spray robots is becoming more and more extensive and the number of color types is increasing, the number of color types sprayed by spray robots is also increasing. Normally, the spray robot sprays the paint through the color-changing valve block group 3 installed on the robot arm. However, due to the increase in the number of color types, the volume and weight of the color-changing valve block group 3 continue to increase, and the weight load borne by the robot's arm is also increasing, and gradually affecting the flexibility and spraying effect of the robot arm. Therefore, based on this, the applicant has developed a multi-color color-changing valve box, that is, the color-changing valve block group 3 is installed in the color-changing valve box instead of installing the color-changing valve block group 3 on the robot's arm, thereby reducing the weight load of the robot arm, improving its spraying effect and operational flexibility, and the color-changing valve box can be installed closer to the robot and can be used in conjunction with different robots.

[0026] like Figure 1 , 2 As shown in Figure 4, the multi-color color-changing valve box is mainly composed of a box body 1. The shape of the box body 1 is not limited, and it can be a rectangular parallelepiped, a cube or a cylinder, etc. The present application preferably uses a rectangular parallelepiped. When placing the box body 1, the length direction of the box body 1 is placed perpendicular to the ground. Of course, it is not necessarily placed on the ground here, but can be placed on a mounting table, which is specifically placed according to the position and height of the robot arm. However, no matter where it is placed, the length direction of the box body 1 is perpendicular to the ground. All positional relationships below are described based on this placement position.

[0027] For example Figure 1 , 2 As shown in Figure 4, a first through hole 11 is provided on the top wall of the box body 1, and a first opening 12 is provided on the bottom wall of the box body 1, and the projection of the first through hole 11 in the axial direction is located in the first opening 12. The purpose of this design is that the paint input pipe can directly extend into the box body 1 from the first opening 12, and be connected to the color-changing valve block group 3 in the box body 1, and then extend from the first through hole 11 through the paint output pipe connected to the color-changing valve block group 3 and be connected to the arm of the spray robot. Compared with the absence of the box body 1, all the paint input pipes will be scattered on the ground or on the workbench, which will not only cause chaos on site, but also be inconvenient to operate. Moreover, the projection of the first through hole 11 in the axial direction is located in the first opening 12, so that the paint input pipe and the paint output pipe can be guaranteed to be in the same plane in space, making the entire structure more compact.

[0028] During operation, all paint input pipes are first extended into the box body 1 from the first opening 12 at the bottom of the box body 1, and then connected to the color-changing valve block group 3 in the box body 1. The paint output pipe connected to the color-changing valve block group 3 is then extended from the first through hole 11 and connected to the robot arm to complete the spraying operation.

[0029] Example 2

[0030] This embodiment is an improvement on the embodiment 1, the difference being that the axis of the first through hole 11 is perpendicular to the top wall of the box body 1 , and the axis of the first through hole 11 coincides with the center line of the normal direction of the first opening 12 .

[0031] Specifically, in order to make the paint output pipe output in a straight line without other bends and avoid smooth paint output, the first through hole 11 is arranged so that its axis is perpendicular to the top wall of the box body 1, and is further arranged so that the axis of the first through hole 11 coincides with the center line of the normal direction of the first opening 12. This design not only avoids the problem of unstable connection or damage caused by installation deviation, but also provides a strong guarantee for the normal operation and long-term use of the box body 1.

[0032] Example 3

[0033] This embodiment is an improvement on the basis of Embodiment 2, the difference being that a connecting tube 2 is provided in the first through hole 11, the connecting tube 2 is movably connected to the first through hole 11, one end of the connecting tube 2 is a paint input end 21, and the other end of the connecting tube 2 is a paint output end 22; wherein the paint input end 21 is connected to the paint output pipeline, and the paint output end 22 is connected to the spray pipeline of the spray robot.

[0034] Specifically, in order to fix the paint output pipe on the box body 1, as shown in FIG. Figure 2 As shown, a connecting pipe 2 is provided in the first through hole 11, and the connecting pipe 2 and the first through hole 11 can be connected by threading or plugging. The paint enters the connecting pipe 2 through the paint input end 21, and after being transmitted by the connecting pipe 2, it is output from the paint output end 22 and enters the spraying pipe of the spraying robot, which is provided on the arm of the robot. The spraying robot realizes uniform spraying of the workpiece by accurately controlling the motion trajectory and spraying speed of the spraying pipe.

[0035] Example 4

[0036] This embodiment is an improvement made on the basis of the embodiment 3, and the difference lies in that a plurality of second through holes 211 are provided on the paint input end 21 of the connecting tube 2, and the plurality of second through holes 211 are respectively connected to a plurality of paint output pipelines one by one.

[0037] Specifically, due to the large variety of paints, when one color-changing valve block cannot carry all colors of paint, multiple color-changing valve blocks can be set, and one color-changing valve block has an output pipeline of paint, so that one output pipeline of paint corresponds to one second through hole 211 on the connecting pipe 2. Therefore, in order to enable the color-changing valve box to accommodate more color-changing valve blocks, such as Figure 3As shown, a plurality of second through holes 211 are provided on the paint input end 21 of the connecting pipe 2, and each second through hole 211 corresponds to a paint output pipeline of a color-changing valve block group 3. Of course, three or even more second through holes 211 can be provided as required, and correspondingly, more color-changing valve blocks 3 are provided in the box body 1.

[0038] Example 5

[0039] This embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that the box body 1 is provided with a plurality of mounting holes 13 penetrating through the side wall, and the mounting holes 13 are used for mounting the color-changing valve block set 3 .

[0040] Specifically, in order to fix the color-changing valve block group 3 in the box body 1, as shown in FIG. Figure 1 and 2 As shown, a plurality of mounting holes 13 are provided on the side wall of the housing 1. Since these mounting holes 13 penetrate the side wall of the housing 1, it is more convenient to install the color-changing valve block assembly 3. The mounting holes 13 can be provided on any side wall as long as the color-changing valve block assembly 3 can be installed on the side wall.

[0041] When installing the color-changing valve block assembly 3, the operator only needs to align the color-changing valve block assembly 3 with the corresponding mounting hole 13, and then use appropriate tools such as a wrench used for bolt fixing to fix it. This installation method is not only quick and simple, but also convenient for later disassembly and maintenance.

[0042] In addition, the number of the mounting holes 13 on the side wall of the box body 1 can be adjusted as needed to accommodate color-changing valve block groups 3 of different models and specifications.

[0043] Example 6

[0044] This embodiment is an improvement made on the basis of Embodiment 5, the difference being that a plurality of the mounting holes 13 are arranged in at least one row, and the mounting holes 13 are arranged along the side wall of the box body 1 from an end close to the first through hole 11 to an end away from the first through hole 11 .

[0045] Specifically, because usually, such as Figure 4 As shown, the color-changing valve block group 3 is rectangular, therefore, in the present application, the mounting holes 13 are arranged in a row, also to match the color-changing valve block group 3, and since multiple colors may be required, multiple color-changing valve block groups 3 are required, therefore, the color-changing valve block groups 3 are arranged in at least one row, and can also be set to two rows, three rows or even more rows according to the number of colors required. When installing the color-changing valve block group 3, it only needs to be installed through the mounting holes 13.

[0046] Example 7

[0047] This embodiment is an improvement made on the basis of Embodiment 6, and the difference lies in that the box body 1 is further provided with a second opening 14 penetrating through the side wall, and the second opening 14 is located on the side wall of the box body 1 opposite to the mounting hole 13 .

[0048] Specifically, Figure 1 , 2 As shown in FIG. 4 , a second opening 14 is also provided through the side wall of the housing 1. The second opening 14 is located on the side wall of the housing 1 opposite to the mounting hole 13. That is, the inner wall of the housing 1 with the mounting hole 13 can be directly seen through the second opening 14. The mounting hole 13 is where the color-changing valve block group 3 is installed. Therefore, the color-changing valve block group 3 and the paint pipeline on the color-changing valve block group 3 can be directly seen through the second opening 14, so that problems can be discovered in time. In practical applications, the second opening 14 can also be used as an auxiliary inlet and outlet for maintenance or observation of the paint input pipe on the color-changing valve block group 3.

[0049] Example 8

[0050] This embodiment is an improvement made on the basis of the embodiment 7, and the difference lies in that an observation window 4 matching with the second opening 14 is further provided on the side wall of the box body 1, and the observation window 4 is made of transparent glass.

[0051] Specifically, in order to facilitate observation of the situation inside the box 1, Figure 1 As shown, an observation window 4 matching the second opening 14 is also provided on the side wall of the box body 1. More specifically, the observation window 4 is made of transparent glass, and the transparent glass observation window 4 can be bonded to the side wall of the second opening 14. In addition, in order to further improve the practicality and safety of the box body 1, a sealing strip can be provided around the observation window 4 to ensure that the connection between the observation window 4 and the box body 1 is tight.

[0052] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
