Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to an automatic spraying device. Background Technology

[0002] Traditionally, spray guns are connected to robotic arms, and controllers direct the spray guns to paint the surface along a pre-planned path. However, ship hulls are generally curved structures, with varying curvature across different ship types, and each type has several vessels, making it impossible to complete the painting process using a pre-planned path. When using traditional methods, the distance between the spray gun and the curved surface cannot be kept constant and perpendicular, resulting in uneven paint thickness and poor painting quality.

[0032] like Figures 1 to 4 As shown, this embodiment provides an automatic painting device, including a drive mechanism, a spray gun 100, a gas collection hood 200, a connector 300, a distance measuring mechanism 400, and a controller (not shown in the figure). The gas collection hood 200 includes a hood body 210, an annular enclosure 220, and an end plate 230. The hood body 210 has a mounting hole and a hood opening facing each other. The annular enclosure 220 passes through the mounting hole and includes an inner enclosure 221 located inside the hood body 210 and an outer enclosure 222 connected to the inner enclosure 221 and extending outside the hood body 210. The end plate 230 is located at... The hood 210 is fixed to the outer end of the outer enclosure 222 away from the inner enclosure 221. The drive mechanism is connected to the spray gun 100 and the outer enclosure 222 through the connector 300. The spray gun 100 passes through the end plate 230 and faces the hood opening. The distance measuring mechanism 400 is installed on the outside of the hood 210 and near the hood opening. The drive mechanism can drive the outer enclosure 222 to move the spray gun 100 and the air collection hood 200 synchronously. The air collection hood 200 is connected to an external air extraction device (not shown in the figure). The drive mechanism, spray gun 100, distance measuring mechanism 400 and external air extraction device are all connected to the controller.

[0033] In this embodiment, the annular enclosure 220 extends through the end plate 230 into the cover 210. The inner enclosure 221 of the annular enclosure 220 divides the cover 210 into a receiving groove 2101 and a gas collecting groove 2102. The spray gun 100 extends through the end plate 230 into the receiving groove 2101 and faces the cover opening. When the external air extraction device is connected to the gas collecting cover 200, the gas collecting groove 2102 communicates with the external air extraction device, and the paint mist is collected by the external air extraction device. The outer enclosure 222 of the annular enclosure 220 is connected to the drive mechanism through the connector 300. Under the action of the controller, the drive mechanism drives the connector 300 to move synchronously, ensuring that the relative position between the nozzle of the spray gun 100 and the gas collecting cover 200 remains unchanged. In this embodiment, under the action of the ranging mechanism 400, the controller can control the drive mechanism to move the spray gun 100 and the air collection hood 200 in real time according to the distance parameters fed back by the ranging mechanism 400, so as to ensure that the spray gun 100 is always perpendicular to the ship's outer plate and keep the distance between the spray gun 100 (the nozzle of the spray gun 100) and the ship's outer plate at a preset value, so as to realize the automated and high-quality spraying of the ship's outer plate with curved surface structure.

[0034] This embodiment deeply integrates paint mist collection and spraying functions, solving the problem of poor tracking performance of the air collection hood 200 in mobile spraying. Through the ranging mechanism 400 and controller, the spraying process is made intelligent, ensuring spraying quality on various complex curved surfaces (such as ship hulls). The design of the "annular enclosure 220" and "end plate 230" is the core to achieve rigid connection and synchronous movement between the spray gun 100 and the air collection hood 200, resulting in a simple and reliable structure. This embodiment can significantly reduce paint mist emissions, meeting environmental protection requirements. Simultaneously, it reduces production costs by improving paint adhesion, lowers the skill requirements and labor intensity for operators, and reduces their exposure time to harmful environments.

[0035] In this embodiment, the ranging mechanism 400 includes a plurality of laser rangefinders, which are installed at intervals on the outer periphery of the cover 210 to detect the distance between the spray gun 100 and the surface to be painted (the outer plate of a ship with a curved structure).

[0036] Furthermore, the length of the annular enclosure 220 extends along the first direction, the width of the annular enclosure 220 extends along the second direction, and the depth of the annular enclosure 220 extends along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The connector 300 includes a first connecting plate 310 and a second connecting plate 320. A first connecting plate 310 is installed on each side of the outer enclosure 222 along the second direction. The spray gun 100 is located between the two first connecting plates 310. The spray gun 100 is connected to the first connecting plate 310 through the second connecting plate 320. The drive mechanism is connected to the first connecting plate 310 in a transmission manner.

[0037] In this embodiment, two first connecting plates 310 and one (or more) second connecting plates 320 together constitute a very stable connector 300. The spray gun 100 and the gas collection hood 200 (outer enclosure 222) are firmly fixed to this connector 300, ensuring that no relative displacement or vibration occurs between the spray gun 100 and the gas collection hood 200 during high-speed or complex movements, resulting in excellent synchronization. The spray gun 100 is located between the two first connecting plates 310; its reasonable layout and compact structure place the spray gun 100 at the center of the driving force, resulting in uniform force distribution and smoother movement.

[0038] Furthermore, there are two spray guns 100, which are spaced apart along the first direction. There are also two second connecting plates 320, which correspond one-to-one with the first connecting plate 310. The spray guns 100 are connected one-to-one with the second connecting plates 320.

[0039] By arranging two spray guns 100 at intervals along the first direction and forming independent connection and transmission paths with their respective second connecting plates 320 and first connecting plates 310, the dual spray guns 100 can expand the spraying coverage area and improve work efficiency, while ensuring that each spray gun 100 can be stably integrated with the drive mechanism and the air collection hood 200 through a rigid connection structure. This ensures the posture stability and motion consistency of the two spray guns 100 during synchronous movement with the air collection hood 200, effectively avoiding the problem of uneven spraying caused by the vibration or asynchrony of the spray guns 100, and maintaining the concentrated collection effect of the air collection hood 200 on the paint mist generated by the dual spray guns 100.

[0040] Furthermore, the drive mechanism includes a first drive assembly, a first mounting base 500, and a second drive assembly. The first drive assembly can drive the first mounting base 500 to move along the X, Y, and Z directions, which are perpendicular to each other. The first drive assembly includes a first drive structure 610, a second drive structure 620, and a third drive structure 630 connected in sequence. The third drive structure 630 is connected to the first mounting base 500. The second drive assembly includes a fourth drive structure 640 and a fifth drive structure 650 connected in sequence. The fourth drive structure 640 is mounted on the first mounting base 500, and the fifth drive structure 650 is connected to the first connecting plate 310. The second drive assembly is mounted on the first mounting base 500 and connected to the first connecting plate 310. The second drive assembly can drive the first connecting plate 310 to rotate about a horizontal axis and about a Z-axis. The first drive structure 610, the second drive structure 620, the third drive structure 630, the fourth drive structure 640, and the fifth drive structure 650 are all connected to a controller.

[0041] In this embodiment, the first drive structure 610, the second drive structure 620, and the third drive structure 630 are sequentially connected to drive the first mounting base 500 to move the connector 300, the spray gun 100, and the air collection hood 200 precisely in the X, Y, and Z directions (the movement in the X, Y, and Z directions does not necessarily correspond one-to-one with the first drive structure 610, the second drive structure 620, and the third drive structure 630; please refer to the following embodiment description for details), ensuring a large-scale positioning coverage of a certain area to be sprayed on the ship's outer plating. Simultaneously, the fourth drive structure 640 and the fifth drive structure 650 enable the connector 300 to drive the spray gun 100 and the air collection hood 200 to rotate synchronously around the horizontal axis and synchronously around the Z-axis, allowing the spray gun 100 to actively adjust its angle to always remain perpendicular and aligned with the complex curved surface of the ship's outer plating. This multi-degree-of-freedom composite motion is all controlled by the controller, enabling the automatic painting device to automatically spray the paint onto the complex curved surface of the ship's outer plating. While ensuring the uniform quality of the paint film and the best collection effect, it significantly improves the automation, adaptability, and overall efficiency of the painting operation.

[0042] Furthermore, such as Figure 2 As shown, the fourth drive structure 640 includes a fourth motor 641, a first drive shaft (not shown in the figure), a drive belt 642, and a mounting bracket 643. The mounting bracket 643 is located on the first mounting base 500 and is fixedly connected to the first drive shaft. The fifth drive structure 650 is mounted on the mounting bracket 643. The drive belt 642 is located below the first mounting base 500. The first drive shaft is connected to the output shaft of the fourth motor 641 via the drive belt 642. The rotation axis of the first drive shaft extends along the Z direction. The fourth motor 641 is connected to the controller.

[0043] In this embodiment, the fourth drive structure 640 transmits the power of the fourth motor 641 to the first drive shaft extending along the Z direction via the transmission belt 642, driving the mounting bracket 643 and the fifth drive structure 650 on it to rotate stably around the Z axis. This layout separates the fixed installation of the fourth motor 641 from the rotating actuator, which optimizes the structural space, reduces the moment of inertia, and ensures smooth and precise rotation around the Z axis through the buffering effect of the belt drive. Thus, in conjunction with the fifth drive structure 650, it enables flexible and stable attitude adjustment of the spray gun 100 and the air collection hood 200 in multiple spatial directions.

[0044] Furthermore, the fifth drive structure 650 includes a fifth motor 651 and a second drive shaft 652. The second drive shaft 652 passes through the mounting bracket 643 and is fixedly connected to the first connecting plate 310. The fifth motor 651 is mounted on the mounting bracket 643. The output shaft of the fifth motor 651 is connected to the second drive shaft 652. The rotation axis of the second drive shaft 652 extends horizontally. The fifth motor 651 can drive the second drive shaft 652 to drive the first connecting plate 310, the second connecting plate 320, the spray gun 100, and the air collection hood 200 to rotate synchronously around the rotation axis of the second drive shaft 652. The fifth motor 651 is connected to the controller.

[0045] The fifth drive structure 650 directly drives the second transmission shaft 652 extending horizontally through the fifth motor 651, thereby driving the first connecting plate 310, spray gun 100 and air collection hood 200 to rotate synchronously around the horizontal axis, realizing the precise and rapid adjustment of the spraying tilt angle of the spray gun 100. This rigid direct transmission method is compact, responsive and has a strong load-bearing capacity, ensuring that the entire end effector can closely adapt to the longitudinal curvature changes of the ship's outer plate, so that the spray gun 100 always maintains the best spraying posture, while ensuring the relative position of the air collection hood 200 and the plate surface, thus achieving both high uniformity of spraying quality and high efficiency of paint mist collection in complex curved surface operations.

[0046] Furthermore, such as Figure 5 and Figure 6 As shown, the first drive structure 610 includes a crossbeam frame 611, a first motor 612, a second mounting base 613, a first transmission part 614, and a first guide part 615 that guides along the X direction. The length of the crossbeam frame 611 extends along the X direction. The second mounting base 613 is slidably connected to the crossbeam frame 611 through the first guide part 615. The first motor 612 and the second drive structure 620 are mounted on the second mounting base 613. The output shaft of the first motor 612 is connected to the crossbeam frame 611 through the first transmission part 614.

[0047] In this embodiment, the first drive structure 610 integrates the first motor 612 and the second drive structure 620 into the second mounting base 613, while the crossbeam frame 611 remains fixed. The second mounting base 613 slides with the crossbeam frame 611 in the X direction via the first guide part 615. The output shaft of the first motor 612 is connected to the first transmission part 614, driving the second mounting base 613 and the first motor 612 itself to move in the X direction. This achieves the unconventional design of "motor moving, beam fixed". Combined with the first guide part 615, it ensures the stability and high precision of the movement of the second mounting base 613 and its entire set of subsequent mechanisms in the X direction, providing a stable and reliable moving foundation for subsequent rotational drives in the Y direction, Z direction, and around the horizontal axis and Z axis.

[0048] Furthermore, there are two sets of first guide parts 615, one set of first guide parts 615 located above the crossbeam frame 611, and the other set of first guide parts 615 located on one side of the crossbeam frame 611 along the Y direction. The first transmission part 614 is located on one side of the crossbeam frame 611 along the Y direction, and the first transmission part 614 is located between the two sets of first guide parts 615. The second mounting base 613 includes a transverse mounting plate 6131 and a longitudinal mounting plate 6132 connected vertically. The transverse mounting plate 6131 is located above the crossbeam frame 611 and passes through... A set of first guide parts 615 slides with the crossbeam frame 611. The longitudinal seat plate 6132 is located on one side of the crossbeam frame 611 along the Y direction. The longitudinal seat plate 6132 slides with the crossbeam frame 611 through another set of first guide parts 615. The first transmission part 614 is located between the longitudinal seat plate 6132 and the crossbeam frame 611. The first motor 612 is installed on the side of the longitudinal seat plate 6132 away from the crossbeam frame 611. The output shaft of the first motor 612 passes through the longitudinal seat plate 6132 and is connected to the first transmission part 614 for transmission.

[0049] In this embodiment, one set of first guide parts 615 is placed above the crossbeam frame 611. The first guide parts 615 bear the main vertical load. The first transmission part 614 is arranged on the Y-direction side of the crossbeam frame 611 and located between the two sets of first guide parts 615. Combined with the L-shaped transverse seat plate 6131 and longitudinal seat plate 6132 design of the second mounting base 613, the overturning moment resistance and overall rigidity of the second mounting base 613 during X-direction movement are improved, ensuring smooth transmission without slippage. At the same time, the structural layout is optimized, making installation and maintenance easier.

[0050] Specifically, the first transmission unit 614 includes a first transmission gear 6141 and a first transmission rack 6142. The first transmission rack 6142 is mounted on the crossbeam frame 611. The lengths of the crossbeam frame 611 and the first transmission rack 6142 extend along the X direction. The output shaft of the first motor 612 is fixedly connected to the first transmission gear 6141. The rotation axis of the first transmission gear 6141 extends along the Y direction. The first transmission gear 6141 meshes with the first transmission rack 6142. The output shaft of the first motor 612 passes through the longitudinal seat plate 6132 and is fixedly connected to the first transmission gear 6141. The first transmission gear 6141 meshes with the first transmission rack 6142. Therefore, the controller can control the first motor 612 to drive the first transmission gear 6141 to rotate. While the first transmission gear 6141 rotates, it moves along the length direction of the first transmission rack 6142 and always maintains meshing with the first transmission rack 6142. This realizes the movement control of the second mounting base 613 driving the first motor 612 and the second drive structure 620 in the X direction.

[0051] Specifically, the two sets of first guide portions 615 have the same structure, each including a first slide rail 6151 and a first slider 6152. Taking the first guide portion 615 placed above the crossbeam frame 611 as an example, the length of the first slide rail 6151 of the first guide portion 615 extends along the X direction. The first slide rail 6151 is installed above the crossbeam frame 611, and the first slider 6152 is fixed below the transverse seat plate 6131, with the first slider 6152 slidingly engaging with the first slide rail 6151. In other embodiments, the first guide portion 615 can also be designed as a guide rod structure. The guide rod is fixed on the crossbeam frame 611, and the transverse seat plate 6131 is provided with a guide hole that slides with the guide rod. The guide rod passes through the guide hole to guide the movement of the second fixed seat along the X direction.

[0052] Furthermore, such as Figures 6 to 8 As shown, the second drive structure 620 includes a longitudinal beam frame 621, a second motor 622, a third mounting base 623, a second transmission part 624, and a second guide part 625 that guides along the Z direction. The longitudinal beam frame 621 is located on one side of the transverse beam frame 611 along the Y direction. The longitudinal beam frame 621 is slidably engaged with the second mounting base 613 through the second guide part 625. The third mounting base 623 is fixed on the second mounting base 613. The second motor 622 is mounted on the third mounting base 623. The output shaft of the second motor 622 is connected to the longitudinal beam frame 621 through the second transmission part 624. The second motor 622 can drive the second transmission part 624 to move the longitudinal beam frame 621 along the Z direction. The third drive structure 630 is mounted on the top of the longitudinal beam frame 621.

[0053] In this embodiment, the second motor 622 is fixed to the third mounting base 623. The second motor 622 drives the second transmission part 624 to move the longitudinal beam frame 621 along the Z direction, thereby realizing the movement of the spray gun 100 and the air collection hood 200 along the Z direction. At the same time, the longitudinal beam frame 621 slides with the second mounting base 613 through the second guide part 625, ensuring the stability of the longitudinal beam frame 621 in the Z direction.

[0054] Specifically, the second transmission unit 624 includes a second transmission gear 6241 and a second transmission rack 6242.

The output shaft of the second motor 622 passes through the third mounting base 623 and is fixedly connected to the second transmission gear 6241. The second transmission gear 6241 meshes with the second transmission rack 6242. The second motor 622 can drive the second transmission gear 6241 to drive the second transmission rack 6242 and the longitudinal beam frame 621 to move up and down under the action of the second guide part 625. The second guide part 625 can provide stability for the up and down movement of the longitudinal beam frame 621.

[0055] Specifically, the second guide portion 625 includes a second slide rail 6251 and a second slider 6252. The second slide rail 6251 is installed on the Y-direction side of the longitudinal beam frame 621 (the side of the longitudinal beam frame 621 facing the transverse beam frame 611), and the length of the second slide rail 6251 extends along the Z-direction. The second slider 6252 is installed on the side of the second mounting base 613 facing the longitudinal beam frame 621 and slides in cooperation with the second slide rail 6251. In other embodiments, the second guide portion 625 can also be designed in a manner where a guide rod and a guide hole cooperate with each other. For example, the guide rod can be set on the side of the longitudinal beam frame 621 near the transverse beam frame 611, and the length of the guide rod can extend along the Z-direction. The second mounting base 613 is provided with a guide hole that cooperates with the guide rod. Further details will not be elaborated further.

The fourth mounting base 632 is fixed to the top of the longitudinal beam frame 621. The fourth mounting base 632 is slidably engaged with the first mounting base 500 through the third guide part 634. The third motor 631 is mounted on the fourth mounting base 632. The output shaft of the third motor 631 is connected to the first mounting base 500 through the third transmission part 633. The third motor 631 can drive the third transmission part 633 to move the first mounting base 500 along the Y direction.

[0057] Specifically, the third transmission unit 633 includes a third transmission gear 6331 and a third transmission rack 6332. The length of the third transmission rack 6332 extends along the Y direction. The third transmission rack 6332 is fixed on the first mounting base 500 and located on the X-direction side of the first mounting base 500. The third transmission gear 6331 is located between the first mounting base 500 and the fourth mounting base 632. The output shaft of the third motor 631 passes through the fourth mounting base 632 and is fixedly connected to the third transmission gear 6331. The third transmission gear 6331 meshes with the third transmission rack 6332. The third motor 631 can drive the third transmission gear 6331 to drive the third transmission rack 6332 and the first mounting base 500 to move along the Y direction. The third guide unit 634 ensures the stability of the movement of the first mounting base 500 along the Y direction.

[0058] The third guide portion 634 includes two third slide rails 6341 and two third sliders 6342. The third slide rails 6341 are installed below the first mounting base 500, and the two third slide rails 6341 are spaced apart along the X direction. The length of the third slide rails 6341 extends along the Y direction. The two third sliders 6342 are installed on the side of the fourth mounting base 632 facing the first mounting base 500 and slide in cooperation with the third slide rails 6341. In other embodiments, the second guide portion 625 can also be designed with two guide rods and two guide holes cooperating with each other. For example, the guide rods can be set on the side of the first mounting base 500 near the fourth mounting base 632, with the length of the guide rods extending along the Y direction. The fourth mounting base 632 is provided with guide holes that cooperate with the guide rods. Further details will not be elaborated further.

[0059] This embodiment also includes a filter box 700 and a connecting pipe (not shown in the figure). The filter box 700 is connected to the gas collection hood 200 through the connecting pipe, and the paint mist is filtered through the filter box 700. In other embodiments, a filter screen can also be installed at the position where the opening of the gas collection hood 200 is directly opposite the gas collection groove 2102 to collect and filter the paint mist.
