Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, specifically to a rotary spray head and a spray painting robot having the same. Background Technology

[0002] Paint spraying robots are industrial robots that can automatically spray paint or other coatings. They mainly consist of a robot body, a computer, and a corresponding control system. They can move flexibly and effectively reduce labor costs. Paint spraying robots can replace manual spraying and reduce the harm of toxic gases generated during the spraying process to the human body.

[0003] Chinese Patent CN221086043U discloses a reciprocating rotary painting device for automotive parts, including a base plate and a rotating assembly comprising two placement plates for holding automotive parts. The bottom of the top plate has two movable connecting plates, with paint supply pipes symmetrically and fixedly connected to both sides of the connecting plates. A spray nozzle is detachably connected to the bottom of each paint supply pipe. This invention enables rapid installation and removal of the spray nozzle, allowing for quick replacement after damage due to blockage or high-pressure impact. It is convenient to operate, requires no auxiliary tools for disassembly, and is highly efficient.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the nozzle can only move and adjust horizontally along the top plate under the drive of the threaded seat. When the size of the parts is large, even if the placement plate is rotated, it cannot be fully sprayed. It is necessary to stop the painting and adjust the position of the parts on the placement plate relative to the nozzle in order to complete the uniform spraying, which reduces the painting efficiency.

Detailed Implementation

[0015] Example 1, as Figures 1 to 4 As shown, the rotary nozzle proposed in this utility model includes a mounting box, a T-tube, a feeding mechanism, and a nozzle. A driving component 202 is installed inside the mounting box. The T-tube is driven to rotate and connected to the bottom of the mounting box via the driving component 202. The driving component 202 consists of a motor, two sets of synchronous pulleys, and a synchronous belt installed outside the two sets of synchronous pulleys. The motor drives one set of synchronous pulleys, and the other set of synchronous pulleys is installed on the outer circumference of the transfer tube 2 in the T-tube. The feeding mechanism consists of a limiting tube 3 installed at the top of the mounting box, two sets of paint inlet pipes 302 symmetrically installed on the limiting tube 3, an air inlet pipe 303 installed in the middle of the limiting tube 3, and a first connecting pipe 20 installed at the bottom of the T-tube. The device consists of four components: the bottom end of the limiting tube 3 extends into the feed chamber 203 of the T-shaped tube, and the limiting tube 3 is rotatably connected to the T-shaped tube; the bottom end of the paint inlet tube 302 is connected to the bottom end of the limiting tube 3, and the outlet end of the paint inlet tube 302 extends into the feed chamber 203; the upper end of the first connecting tube 204 is rotatably connected to the bottom end of the limiting tube 3; and the bottom end of the air inlet tube 303 is rotatably connected to the inner wall of the first connecting tube 204. Two sets of nozzles are provided, and the two sets of nozzles are symmetrically and obliquely installed on the T-shaped tube through a bracket. The outlet end of the T-shaped tube is connected to the second connecting tube 404 on the two sets of nozzles through a hose, and the output end of the first connecting tube 204 is connected to the air jet pipe 405 on the two sets of nozzles through a hose.

[0016] Furthermore, the mounting box consists of a base 1 and a housing 101 that is detachably mounted to the base 1 by bolts. A mounting plate 301 is provided on the outer circumference of the limiting tube 3. The mounting plate 301 is connected to the inner wall of the top of the housing 101 by bolts. A door is hinged to the side wall of the housing 101. The other end of the door is detachably connected to the housing 101 by a latch, which facilitates opening the door to inspect the internal components of the housing 101. The entire mounting box is detachable, which facilitates disassembly and maintenance.

[0017] Furthermore, the T-shaped tube consists of a rotating tube 2 connected to the rotating base 1 and two sets of extension tubes 201 symmetrically installed on the rotating tube 2. The extension tubes 201 are connected to the feed chamber 203 at the bottom of the rotating tube 2.

[0018] Furthermore, the nozzle includes a paint spray base 4 and a mounting cavity 402; the paint spray base 4 is provided with a paint cavity 401 inside, and the paint spray base 4 is installed at an angle at the bottom end of the extension tube 201 by a bracket, so that the paint sprayed from the output ends of the two sets of nozzles converges from different directions; the mounting cavity 402 is located in the middle of the paint spray base 4, and the paint cavities 401 are distributed around the periphery of the mounting cavity 402. Multiple sets of paint spray holes 403 are evenly opened at the connection between the paint cavity 401 and the mounting cavity 402. The second connecting tube 404 is installed at the top of the paint spray base 4, and the input end of the second connecting tube 404 is connected to the paint cavity 401. The output end of the air jet tube 405 extends into the interior of the mounting cavity 402.

[0019] Furthermore, the bottom of the paint spraying station 4 is equipped with a gathering cover connected to the mounting cavity 402, which facilitates the gathering of scattered paint particles and avoids them being too dispersed and affecting the painting effect. The output end of the air jet pipe 405 is equipped with an air diffuser, which corresponds to multiple sets of paint spraying holes 403, so as to quickly blow the sprayed paint particles into fine particles and make them evenly contact the workpiece.

[0020] In this embodiment, the external paint supply mechanism and the air pump are connected to the paint inlet pipe 302 and the air inlet pipe 303, respectively. The paint spraying system controls the drive unit 202 to start the drive tube 2 to rotate along the base 1. When the tube 2 rotates, it drives the two sets of extension tubes 201 to rotate. At the same time, the first connecting pipe 204 installed at the bottom of the tube 2 rotates along the limiting pipe 3 and the air inlet pipe 303. The paint enters the feed chamber 203 from the paint inlet pipe 302, and then quickly enters the extension tubes 201 under the action of centrifugal force. Finally, it is delivered to the oil pump by the hose and the second connecting pipe 404. In the paint chamber 401, the paint is sprayed out from multiple sets of spray holes 403. At the same time, high-pressure gas enters the first connecting pipe 204 along the air inlet pipe 303 and is then transported to the jet pipe 405 through the hose. It is then sprayed out by the air diffuser. The high-pressure gas can quickly blow the paint into fine particles and spray them toward the workpiece. Since the two sets of paint spray seats 4 are symmetrically inclined relative to the T-shaped tube, the paint sprayed from the converging hoods at the output ends of the two sets of nozzles converges from different directions. With the rotation of the T-shaped tube, the sprayed paint can fully contact the workpiece, improve the painting efficiency, and avoid the formation of painting dead angles.

[0021] Example 2, as Figure 1 As shown, the painting robot proposed in this utility model includes a robot body, a computer, a painting control system, a placement platform, and a rotating spray head as shown in Embodiment 1. The top of the housing 101 is provided with multiple sets of mounting legs 102, and multiple sets of mounting holes are opened on the mounting legs 102. The mounting holes are connected to the output end of the robot body by fastening bolts. The robot body, computer, placement platform, and painting control system are all existing technologies. The robot body can be a six-axis robotic arm. Those skilled in the art can clearly understand the working principle and structure.

[0022] In this embodiment, the workpiece is placed on the placement table, and the robot body is controlled by the paint spraying control system in the computer to drive the rotating spray head to adjust the spraying angle and position, so that the workpiece can be sprayed from all directions, thus improving the painting efficiency.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
