[0023] The following is combined with Figure 1-5 The embodiments of the present utility model are described in detail.

[0024] Example 1

[0025] The utility model relates to a bracket for an automatic powder spray gun 100, which is used to connect a spraying robot 200 and the automatic powder spray gun 100, and comprises a mounting seat 1, a connecting piece 2, a support rod 3 and an angle adjustment mechanism 6, wherein the mounting seat 1 is used to connect with the automatic powder spray gun 100, the connecting piece 2 is used to connect with the spraying robot 200, one end of the support rod 3 is connected with the mounting seat 1, and the connecting piece 2 at the other end of the support rod 3 is connected; the angle adjustment mechanism 6 comprises a slide groove 61 provided on the side wall of the support rod 3 and a connecting rod 62 hinged to the mounting seat 1; a positioning groove 63 is provided at the bottom of the slide groove 61, a slider 64 is provided in the slide groove 61, the slider 64 is located above the positioning groove 63, and one end of the slider 64 is connected to the connecting rod 62; in the working state, the connecting rod 62 drives the slider 64 to slide in the slide groove 61, so that different sizes of angles are formed between the mounting seat 1 and the support rod 3. Here, the mounting seat 1 and the support rod 3 are hinged together by fixing plates provided on both sides of the support rod 3.

[0026] Since the automatic powder spray gun 100 needs to be maintained after being used for a period of time, or it may fail during use, it needs to be removed and reinstalled on the manipulator for spraying after the inspection is completed. However, when a failure occurs during the spraying process, it may be installed again. The installation angle may be inconsistent with the previous one, which is easy to cause inconsistent spraying effects, or in order to make the spraying effect consistent, it is necessary to manually adjust the installation angle with the spraying end of the spraying robot 200 repeatedly. Based on this, the applicant designed the automatic powder spray gun 100 bracket in this application, connected the automatic powder spray gun 100 and the spraying robot 200 through the bracket, and set the angle adjustment structure 6 on the bracket, and set the angle between the mounting seat 1 and the support rod 3 to be variable, which can not only be applied to different workpieces, but also can be removed midway. After that, the connecting rod 62 is fixed in the slide 61 by bolts, that is, the angle between the mounting seat 1 and the support rod 3 is fixed, and then when the automatic powder spray gun 100 is installed again, the angle is consistent with the previous one, ensuring that the installation angle is fixed each time.

[0027] Specifically, Figure 1 , 2 As shown in Figure 5, the bracket of the automatic powder spray gun 100 includes a mounting seat 1, a connecting piece 2, a support rod 3 and an angle adjustment structure 6, wherein the mounting seat 1 is used to mount the automatic powder spray gun 100, the support rod 3 is used to support the mounting seat 1, one end of which is connected to the mounting seat 1 and the other end is connected to the connecting piece 2, the connecting piece 2 is used to connect the manipulator, and the angle adjustment structure 6 is used to adjust the angle between the mounting seat 1 and the support rod 3. The mounting seat 1 is perpendicular to the support rod 3, and the support rod 3 is arranged parallel to the manipulator. Figure 4As shown, the angle adjustment mechanism includes a slide groove 61 provided on the side wall of the support rod 3 and a connecting rod 62 hinged to the mounting seat 1; in order to enable the connecting rod 62 to slide freely on the support rod 3, a positioning groove 63 is provided at the bottom of the slide groove 61, and a slider 64 is provided in the slide groove 61, the slider 64 is located above the positioning groove 63, and one end of the slider 64 is connected to the connecting rod 62; when spraying, first adjust the angle between the mounting seat 1 and the support rod 3, and then extend the bolt into the positioning groove 63 to fix the connecting rod 62 in the slide groove 61. Similarly, when the automatic powder spray gun 100 is removed, the fixed angle remains unchanged, so that the spraying trajectory of the automatic powder spray gun 100 is consistent after the automatic powder spray gun 100 is installed again.

[0028] Example 2

[0029] In order to further improve the stability of the operation of the spraying robot 200, and to enable the spraying robot 200 to adapt to workpieces of more specifications and improve its scope of use, the angle formed between the mounting seat 1 and the support rod 3 is θ in this application, 100°<θ<150°. In addition, the angle is set to 100°<θ<150°, because the angle range formed after the mounting seat 1 and the support rod 3 are hinged, when the angle is greater than 150°, the mounting seat 1 is easy to affect the stability of the hinge under the action of its own gravity, and when the angle is less than 100°, the mounting seat 1 will block the support rod 3 from moving to the side close to the manipulator. Therefore, considering the above, the angle θ is set to 100°<θ<150°.

[0030] Example 3

[0031] This embodiment is an improvement on the embodiment 1, the difference being that limiting grooves 4 are symmetrically provided on both sides of the mounting seat 1, and limiting holes 5 are provided through the two limiting grooves 4 for corresponding to the mounting holes 101 on the automatic powder spray gun 100.

[0032] Specifically, Figure 1 and 2 As shown, the mounting seat 1 is perpendicular to the support rod 3, and the support rod 3 is arranged parallel to the manipulator. The mounting seat 1 is preferably a rectangular block, and a limiting groove 4 is provided on both sides of the rectangular block, and a limiting hole 5 is provided in the center of the limiting groove 4, so that the mounting end of the automatic powder spraying gun 100 can be inserted into the limiting groove 4. The structural schematic diagram of the automatic powder spraying gun 100 is shown in FIG. Figure 3 As shown, the automatic powder spray gun 100 is fixed on the mounting seat 1 by docking the mounting hole on the mounting end with the limiting hole 5. It should be noted that the shape of the limiting groove 4 is consistent with the shape of the mounting end of the automatic powder spray gun 100. When the mounting end is matched with the limiting groove 4, the mounting end is actually embedded in the limiting groove 4, so that the automatic powder spray gun 100 cannot be rotated at will, and the angle is always only one, thereby ensuring that the spraying trajectory of the automatic powder spray gun 100 is consistent.

[0033] Example 4

[0034] This embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that a first auxiliary hole 31 is formed through the support rod 3 at one end away from the mounting seat 1 , and the first auxiliary hole 31 is formed along the length direction of the support rod 3 .

[0035] Specifically, since the powder coating of the automatic powder spraying gun 100 passes through the robot through the coating tube and is connected to the automatic powder spraying gun 100, and in order to protect the coating tube, a bellows is also provided outside the coating tube. Therefore, when the coating tube with the bellows passes through the robot, it is necessary to manually pull the bellows and the coating tube. In order to facilitate the smooth passing of the bellows from the robot, Figure 1 and 2 As shown, at one end of the support rod 3 away from the mounting seat 1, i.e., the end connected to the manipulator, a first auxiliary hole 31 is formed through the support rod 3, so that when the bellows is passed out of the manipulator, a hand can be inserted through the first auxiliary hole 31 to assist the bellows to pass out. The first auxiliary hole 31 can be oval or circular, as long as a hand can be inserted into the hole to assist the bellows to pass out.

[0036] Example 5

[0037] This embodiment is an improvement on the basis of the embodiment 4, and the difference lies in that the first auxiliary hole 31 is U-shaped with an opening, and positioning holes 32 are symmetrically arranged on both sides of the opening on the support rod 3, and a combining hole matching the positioning hole 32 is provided on the connecting member 2, and the positioning hole 32 and the combining hole connect the support rod 3 and the connecting member 2.

[0038] Specifically, in order to further facilitate the passing of the bellows from the robot, as Figure 1 and 2 As shown, the first auxiliary hole 31 is in a U-shape with an opening, and the opening direction is opposite to the manipulator, so that when the bellows passes through the manipulator, the operator's hand can directly extend into the U-shaped opening. In order to connect the support rod 3 and the connecting member 2, positioning holes 32 are symmetrically arranged on both sides of the U-shaped opening on the support rod 3, and a coupling hole matching the positioning holes 32 is opened on the connecting member 2, so that the two can be fixed by bolts.

[0039] Example 6

[0040] This embodiment is an improvement made on the basis of Embodiment 5, and the difference lies in that a plurality of through holes 33 are further penetrated through the support rod 3 , and the centers of the plurality of through holes 33 and the first auxiliary hole 31 are located on the center line of the support rod 3 .

[0041] Specifically, in order to make the robot have a smaller weight load during the spraying process and make it flexible in spraying, Figure 1 and 2 As shown, a plurality of through holes 33 are also formed on the support rod 3 to reduce the weight of the support rod 3, thereby reducing the weight load of the manipulator. Furthermore, in order to stabilize the center of gravity of the support rod 3, the centers of the plurality of through holes 33 and the first auxiliary hole 31 are all set on the center line of the support rod 3, so that during the rotation of the manipulator, the forces in all directions are equal and the center of gravity is unique.

[0042] Example 7

[0043] This embodiment is an improvement made on the basis of the embodiment 1, and the difference is that the connecting member 2 is a flange.

[0044] Specifically, in order to connect the support rod 3 with the spraying robot 200, the connecting piece 2 provided between the support rod 3 and the spraying robot 200 is a flange, more specifically, a circular flange. The flange connection is selected because it has a simple structure, is easy to install and is flexible to disassemble. At the same time, since the flange is connected by bolts that are easy to disassemble and repair, it is also easy to disassemble the entire automatic powder spray gun 100 bracket from the manipulator of the spraying robot 200.

[0045] Example 8

[0046] This embodiment is an improvement made on the basis of the embodiment 1, and the difference lies in that the bracket of the automatic powder spray gun 100 is made of aluminum alloy.

[0047] Specifically, since the automatic powder spray gun bracket is set at the end of the manipulator of the spray robot, if it is too heavy, the spray robot will bear a large weight load, affecting its flexibility. Therefore, the automatic powder spray gun bracket in this application is made of a lightweight and durable aluminum alloy material, which not only reduces the overall weight but also ensures the stability of the bracket. In addition, the thermal conductivity of aluminum alloy is good, which means that the automatic powder spray gun bracket is not prone to overheating after long-term use, thereby ensuring the stable operation of the automatic powder spray gun.

[0048] 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.
