[0033] The present application embodiment discloses a nine-axis spraying workstation, referring to Figure 1 , including a nine-axis spraying device 1 and a protective device 2. The nine-axis spraying device 1 is used to spray the product, and the protective device 2 is used to isolate and protect the product to be sprayed to prevent the gas and powder generated by the spraying operation from scattering in the air and affecting the health of the workers.

[0034] Reference Figure 1 and Figure 2, the nine-axis spraying device 1 is located on one side of the protective device 2, the protective device 2 has a spraying point 3, and the nine-axis spraying device 1 extends into the spraying point 3 to perform a spraying operation. Specifically, the nine-axis spraying device 1 includes a support seat 11, a six-axis manipulator 12, a nozzle 13, and a multi-station stage 14. The support seat 11 is located on one side of the spraying point 3 to support the six-axis manipulator 12, the nozzle 13, and the multi-station stage 14. The six-axis manipulator 12 is a conventional automation equipment and will not be described in detail here. The six-axis manipulator 12 is installed on the upper surface of the support seat 11, and the nozzle 13 is installed at the end of the six-axis manipulator 12. The action of the six-axis manipulator 12 controls the nozzle 13 to extend into the spraying point 3 to perform a spraying operation. The multi-station stage 14 supports and fixes the product to be sprayed to improve the stability of the spraying operation of the nozzle 13. At the same time, the multi-station stage 14 is rotatably connected to the support seat 11. The multi-station stage 14 has multiple loading stations for carrying the products to be sprayed, and the multiple loading stations can all be rotated to the spraying point 3, so that the six-axis manipulator 12 controls the nozzle 13 to spray the product on the loading station located at the spraying point 3.

[0035] Reference Figure 1 and Figure 2 The multi-station stage 14 includes a rotating frame 141, a first stage 142 and a second stage 143. The rotating frame 141 is horizontally arranged, and the rotating frame 141 is horizontally rotatably connected to the support seat 11, and the rotation position of the rotating frame 141 and the support seat 11 is the middle position of the rotating frame 141. The first stage 142 and the second stage 143 are respectively arranged at both ends of the rotating frame 141, and the first stage 142 and the second stage 143 are symmetrically arranged relative to the support seat 11. At the same time, the first stage 142 and the second stage 143 are both rotatably connected to the rotating frame 141. It should be noted that the first stage 142 is rotatably connected to one end of the rotating frame 141 to form the seventh axis of the nine-axis spraying device 1, the second stage 143 is rotatably connected to the other end of the rotating frame 141 to form the eighth axis of the nine-axis spraying device 1, and the rotating frame 141 is rotatably connected to the support seat 11 to form the ninth axis of the nine-axis spraying device 1. When the product on the first stage 142 is undergoing a spraying operation, the product on the second stage 143 can undergo a material change operation. When the product on the second stage 143 is undergoing a spraying operation, the product on the first stage 142 can undergo a material change operation, thereby saving material change time and thus being beneficial to improving spraying efficiency.

[0036] Reference Figure 1 and Figure 2The first stage 142 includes a first rotating seat 1421 and a first fixing member 1422. The first rotating seat 1421 is horizontally rotatably connected to one end of the rotating frame 141. The first fixing member 1422 is detachably connected to the first rotating seat 1421 for fixing the product to be sprayed. The first rotating seat 1421 drives the product fixed by the first fixing member 1422 to rotate, thereby adjusting the orientation of the product during the spraying process to improve the comprehensiveness and convenience of the spraying operation. In this embodiment, the first fixing member 1422 fixes the product by clamping, and the first fixing member 1422 is detachably connected to the first rotating seat 1421 by bolts.

[0037] Similar to the first loading platform 142, the second loading platform 143 includes a second rotating seat 1431 and a second fixing member 1432. The second rotating seat 1431 is rotatably connected to the other end of the rotating frame 141. The second fixing member 1432 is detachably connected to the second rotating seat 1431 for fixing the product to be sprayed. The second rotating seat 1431 drives the product fixed by the second fixing member 1432 to rotate, thereby adjusting the orientation of the product during the spraying process to improve the comprehensiveness and convenience of the spraying operation. In this embodiment, the second fixing member 1432 also fixes the product by clamping, and the second fixing member 1432 is also detachably connected to the second rotating seat 1431 by bolts.

[0038] Reference Figure 1 and Figure 3 , the protective device 2 covers the spraying point 3 and isolates the loading station located at the spraying point 3 from other loading stations to achieve a protective effect. Specifically, the protective device 2 includes a protective cover 21, and the protective cover 21 covers the spraying point 3. At the same time, the protective cover 21 is provided with an opening 4 for the first loading platform 142 or the second loading platform 143 to enter and exit the side wall facing the nine-axis spraying device 1. In addition, an air suction system (not shown in the figure) is arranged in the protective cover 21. The air suction system is located on the inner side wall of the protective cover 21 away from the opening 4, and the air suction port of the air suction system faces the opening 4 to suck away the gas and powder generated in the protective cover 21, which is beneficial to prevent the gas and powder from scattering, thereby further protecting the health of the staff.

[0039] Reference Figure 3 and Figure 4 The protective device 2 also includes a door mechanism 22 for opening and closing the opening 4. When the nozzle 13 performs a spraying operation, the door mechanism 22 reduces the width of the opening 4 to reduce the gas and powder generated by the spraying operation from floating out of the protective cover 21. When the multi-station stage 14 performs a rotating operation, the door mechanism 22 increases the width of the opening 4 to avoid the rotation operation of the multi-station stage 14.

[0040] Reference Figure 3 and Figure 4 The door mechanism 22 includes door blades 221 and a driving assembly 222. The number of the door blades 221 is set to two. The two door blades 221 are located at the position of the opening 4. The two door blades 221 are vertically oppositely arranged and are horizontally slidably connected to the protective cover 21. The driving assembly 222 is arranged on the protective cover 21 to drive the two door blades 221 to move toward or away from each other, so as to change the width of the opening 4.

[0041] Specifically, the driving assembly 222 includes a driving motor 2221, a bidirectional screw rod 2222, and two connecting blocks 2223. The driving motor 2221 is horizontally fixedly arranged at one side of the bottom of the protective cover 21, the bidirectional screw rod 2222 is coaxially fixedly connected to the output shaft of the driving motor 2221, the two connecting blocks 2223 are respectively threadedly sleeved on both ends of the bidirectional screw rod 2222, and the two door leaves 221 are respectively vertically fixedly connected to the two connecting blocks 2223. When the driving motor 2221 is started, the output shaft of the driving motor 2221 drives the bidirectional screw rod 2222 to rotate, and the rotation of the bidirectional screw rod 2222 drives the two connecting blocks 2223 to move in a direction of approaching or moving away from each other, and the two connecting blocks 2223 drive the two door leaves 221 to move in a direction of approaching or moving away from each other, thereby changing the width of the opening 4. It should be noted that the driving assembly 222 also includes a limit plate 2224, which is horizontally fixedly connected to the protective cover 21, and the plate surface of the limit plate 2224 abuts against the side walls of the two connecting blocks 2223 to prevent the connecting blocks 2223 from rotating during movement, thereby helping to improve the stability of the connecting blocks 2223 during movement.

[0042] The implementation principle of a nine-axis spraying workstation in the embodiment of the present application is as follows: when spraying operation is required, the staff fixes the product to be sprayed on the first stage 142 and the second stage 143, and then the rotating frame 141 rotates to allow the first stage 142 to drive the product to be sprayed to move to the spraying point 3, and the six-axis manipulator 12 drives the nozzle 13 to spray the product located at the spraying point 3. After the spraying operation of the product on the first stage 142 is completed, the rotating frame 141 rotates to allow the second stage 143 to drive the product to be sprayed to move to the spraying point 3, and the six-axis manipulator 12 drives the nozzle 13 to continue the spraying operation. During the spraying process, the staff performs a material change operation on the product on the first stage 142, which saves the material change time, thereby helping to improve the spraying efficiency. During the spraying operation, the protective cover 21 covers the spraying point 3, and the suction system sucks away the gas and powder generated in the protective cover 21, which helps to prevent the gas and powder generated by the spraying operation from scattering, thereby protecting the health of the staff.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
