Description

Technical Field

[0001] This utility model relates to the field of spray gun nozzle switching technology, and in particular to an automatic spraying robot spray gun nozzle switching device. Background Technology

[0002] Currently, in the field of automated spraying, spraying robots are widely used due to their efficient and precise spraying performance. During the spraying process, the switching of spray nozzles is a key step to achieve spraying of different colors or materials. However, traditional spray nozzle switching methods often have many inconveniences and problems.

[0003] Traditional spray gun nozzle switching relies heavily on manual operation, which not only increases the labor intensity of workers but also results in low switching efficiency, making it difficult to meet the needs of large-scale, high-efficiency production. In addition, errors are prone to occur during manual switching, leading to unstable spraying quality and affecting the appearance and quality of products.

[0004] To address these issues, we propose an automatic spraying robot nozzle switching device. This device can automatically, quickly, and stably switch spraying nozzles, while also reducing the labor intensity of workers. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic spraying robot spray gun nozzle switching device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic spraying robot nozzle switching device includes: a spray gun, a tube connected to the other side of the bottom of the spray gun, a limiting mechanism installed inside the tube, a limiting frame inserted into the bottom of the tube, a lifting and separating component fixedly installed on the top of the limiting frame, a pressing component installed inside the lifting and separating component, and the bottom of the limiting frame fixedly installed to the top of the workbench.

[0008] Preferably, the limiting mechanism includes limiting grooves opened on both sides of the inner cavity of the insert, limiting blocks slidably installed in both sets of limiting grooves, wedge blocks fixedly installed on the inner sides of both sets of limiting blocks, piston holes opened in the middle of the other side of the two sets of limiting grooves, piston rods movably installed in the two sets of piston holes, and first springs sleeved in both sets of piston rods. The first springs in each set are fixedly installed on the inner wall of the limiting groove and the side wall of the wedge block on both sides, which can fix the spray gun.

[0009] Preferably, the lifting and separating assembly includes a support column fixedly installed on the top of the limiting frame, an upper hemispherical cover fixedly installed on the top of the support column, and a lower hemispherical cover slidably installed on the bottom of the support column. The upper and lower hemispherical covers are respectively connected to the inclined sides of two sets of wedge blocks, which can separate the wedge blocks from the lower and upper hemispherical covers.

[0010] Preferably, a connector is fixedly installed on the top of the spray gun, and the connector is detachably installed with the drive end of the spraying robot. A nozzle is installed in communication with one side of the bottom of the spray gun, and a spray pipe is installed in communication with the side wall of the spray gun. The spray pipe and the nozzle are interconnected, which facilitates the installation of the spray gun.

[0011] Preferably, the extrusion assembly includes a groove in the middle of the bottom of the upper hemisphere, a second spring fixedly installed on the inner wall of the groove, and a retaining ring fixedly installed on the other end of the second spring, which can support the lower hemisphere.

[0012] Preferably, the abutment ring is slidably connected to the support column, the abutment ring fits into the groove, and the bottom of the abutment ring corresponds to the top of the lower hemisphere cover, so that the abutment ring can be stored.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention combines a limiting mechanism with a lifting and separating component. When the two sets of wedge blocks move to the bottom of the upper hemisphere, the wedge blocks will be limited between the lower and upper hemispheres, thus limiting the spray gun and ensuring its firmness and stability on the limiting frame. At the same time, when the painting robot uses the spray gun, it will push the lower hemisphere to the bottom of the upper hemisphere, so that the lower and upper hemispheres combine to form a spherical cover with the side walls forming an arc shape. This ensures that as the two sets of wedge blocks move upward, they will detach from the lower and upper hemispheres, allowing the painting robot to quickly remove the spray gun for use.

[0015] A second spring is fixedly installed on the inner wall of the groove, and a stop ring is fixedly installed on the other end of the second spring. After the lower hemisphere and the upper hemisphere are combined to form a spherical cover, and the two sets of wedge blocks are separated from the side walls of the lower hemisphere and the upper hemisphere, the stop ring is squeezed by the second spring in the groove, which can separate the lower hemisphere and the upper hemisphere that are attached to each other. This makes it easier for the spraying robot to fix the spray frame again when it inserts the spray gun into the limit frame. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An automatic spraying robot spray gun nozzle switching device includes: a spray gun 1, a tube 11 connected to the other side of the bottom of the spray gun 1, a limiting mechanism installed inside the tube 11, a limiting frame 12 inserted into the bottom of the tube 11, a lifting and separating component fixedly installed on the top of the limiting frame 12, a squeezing component installed inside the lifting and separating component, and the bottom of the limiting frame 12 fixedly installed on the top of the workbench 13.

[0023] Furthermore, the extrusion assembly includes a groove 33 in the middle of the bottom of the upper hemisphere 32, a second spring 34 fixedly installed on the inner wall of the groove 33, and a retaining ring 35 fixedly installed on the other end of the second spring 34. This assembly supports the lower hemisphere 31. When the lower hemisphere 31 and the upper hemisphere 32 are combined to form a spherical cover, and the two sets of wedge blocks 22 are disengaged from the side walls of the lower hemisphere 31 and the upper hemisphere 32, the retaining ring 35 is extruded by the second spring 34 in the groove 33. This separates the lower hemisphere 31 and the upper hemisphere 32, making it easier for the spraying robot to re-insert the spray gun 1 onto the limiting frame 12 and then re-fix the spray frame. By combining the limiting mechanism with the lifting and separating component, when the two sets of wedge blocks 22 move to the bottom of the upper hemisphere 32, the wedge blocks 22 will be limited between the lower hemisphere 31 and the upper hemisphere 32, limiting the spray gun 1 and ensuring that the spray gun 1 is firm and stable on the limiting frame 12. At the same time, when the painting robot uses the spray gun 1, it will push the lower hemisphere 31 to the bottom of the upper hemisphere 32, so that the lower hemisphere 31 and the upper hemisphere 32 are combined into a spherical cover, and the side wall is arc-shaped. This ensures that after the two sets of wedge blocks 22 move upward, they will separate from the lower hemisphere 31 and the upper hemisphere 32, so that the painting robot can quickly take out the spray gun 1 for use.

[0024] Furthermore, the abutment ring 35 is slidably connected to the support column 3, and the abutment ring 35 fits into the groove 33. The bottom of the abutment ring 35 corresponds to the top of the lower hemisphere cover 31, which can store the abutment ring 35. After the lower hemisphere cover 31 and the upper hemisphere cover 32 are combined into a spherical cover, the lower hemisphere cover 31 can press the abutment ring 35 into the groove 33 at the bottom of the upper hemisphere cover 32, storing the abutment ring 35 inside the upper hemisphere cover 32, so that the lower hemisphere cover 31 and the upper hemisphere cover 32 are completely closed.

[0025] Furthermore, the limiting mechanism includes limiting grooves 2 opened on both sides of the inner cavity of the insert 11, limiting blocks 21 slidably installed in both sets of limiting grooves 2, wedge blocks 22 fixedly installed on the inner side of both sets of limiting blocks 21, piston holes 23 opened in the middle of the other side of the two sets of limiting grooves 2, piston rods 24 movably installed in the two sets of piston holes 23, and first springs 25 sleeved in both sets of piston rods 24. Each set of first springs 25 is fixedly installed on the inner wall of the limiting groove 2 and the side wall of the wedge block 22 on both sides, which can fix the spray gun 1. A connector is fixedly installed on the top of the spray gun 1. The connector is detachably installed with the drive end of the spraying robot. A nozzle 14 is installed on one side of the bottom of the spray gun 1. A spray pipe is installed on the side wall of the spray gun 1. The spray pipe is connected to... The nozzles 14 are interconnected, facilitating the installation of the spray gun 1. After the spraying robot completes the spraying, the spray gun 1 is moved to the top of the workbench 13, and the insert 11 on one side of the bottom of the spray gun 1 is inserted into the top of the limiting frame 12. After the two sets of wedge blocks 22 inside the insert 11 are in contact with the top sides of the upper hemisphere cover 32, as the insert 11 moves down, the side wall of the upper hemisphere cover 32 will press against the inclined side of the wedge block 22, compressing the first spring 25 installed on the outside of the piston rod 24, causing the wedge block 22 to move horizontally along the direction of the limiting groove 2. When the two sets of wedge blocks 22 move to the bottom of the upper hemisphere cover 32, the wedge block 22 will be limited between the lower hemisphere cover 31 and the upper hemisphere cover 32, limiting the spray gun 1 and ensuring that the spray gun 1 is firm and stable on the limiting frame 12.

[0026] Furthermore, the lifting separation assembly includes a support column 3 fixedly installed on the top of the limiting frame 12, an upper hemispherical cover 32 fixedly installed on the top of the support column 3, and a lower hemispherical cover 31 slidably installed on the bottom of the support column 3. The upper hemispherical cover 32 and the lower hemispherical cover 31 correspond to the inclined sides of two sets of wedge blocks 22 on both sides, which can separate the wedge blocks 22 from the lower hemispherical cover 31 and the upper hemispherical cover 32. When the spraying robot uses the spray gun 1, the drive end of the spraying robot connects to the upper connector of the spray gun 1. The robot connects and continuously presses down on the insert 11, causing the two sets of wedge-shaped blocks 22 inside the insert 11 to be squeezed to the bottom of the lower hemispherical cover 31. As the spraying robot moves the spray gun 1 upward again, it will push the lower hemispherical cover 31 to the bottom of the upper hemispherical cover 32, so that the lower hemispherical cover 31 and the upper hemispherical cover 32 are combined into a spherical cover, and the side wall is arc-shaped. This ensures that the two sets of wedge-shaped blocks 22 will separate from the lower hemispherical cover 31 and the upper hemispherical cover 32 as they move upward, allowing the spraying robot to quickly take out the spray gun 1 for use.

[0027] In use, the limiting mechanism first engages with the lifting and separating components. After the painting robot completes the painting, it moves the spray gun 1 to the top of the workbench 13 and inserts the insert 11 on one side of the bottom of the spray gun 1 into the top of the limiting frame 12. After the two sets of wedge blocks 22 inside the insert 11 come into contact with the top sides of the upper hemisphere cover 32, as the insert 11 moves downward, the side wall of the upper hemisphere cover 32 will press against the inclined side of the wedge block 22, compressing the first spring 25 installed on the outside of the piston rod 24, causing the wedge block 22 to move horizontally along the direction of the limiting groove 2. When the two sets of wedge blocks 22 move to the bottom of the upper hemisphere cover 32, the wedge block 22 will be limited between the lower hemisphere cover 31 and the upper hemisphere cover 32, limiting the spray gun 1 and ensuring that the spray gun 1 is firm and stable on the limiting frame 12. At the same time, when the painting robot uses the spray gun 1, the drive end of the painting robot connects with the upper connector of the spray gun 1 and continuously presses down the insert 11, causing the two wedge blocks 22 inside the insert 11 to come into contact with the top sides of the upper hemisphere cover 32. The wedge blocks 22 are pressed against the bottom of the lower hemispherical cover 31. As the painting robot moves the spray gun 1 upward again, it pushes the lower hemispherical cover 31 to the bottom of the upper hemispherical cover 32, so that the lower hemispherical cover 31 and the upper hemispherical cover 32 combine to form a spherical cover, and the side wall is rounded. This ensures that the two sets of wedge blocks 22 will separate from the lower hemispherical cover 31 and the upper hemispherical cover 32 as they move upward, allowing the painting robot to quickly remove the spray gun 1 for use. At the same time, the second set of wedge blocks 22 is fixedly installed through the inner wall of the groove 33. Spring 34, and the other end of the second spring 34 is fixedly installed with a stop ring 35. After the lower hemisphere cover 31 and the upper hemisphere cover 32 are combined to form a spherical cover, and the two sets of wedge blocks 22 are separated from the side walls of the lower hemisphere cover 31 and the upper hemisphere cover 32, the stop ring 35 is squeezed by the second spring 34 in the groove 33, which can separate the lower hemisphere cover 31 and the upper hemisphere cover 32 that are attached to each other, so that when the spraying robot inserts the spray gun 1 into the limiting frame 12 again, the spray frame can be fixed again.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
