Description

Technical Field

[0001] The present disclosure relates to a painting device and a painting method, and more particularly, to a painting device and a painting method capable of improving painting efficiency and painting quality. Background Art

[0002] When maintaining a workpiece having a plurality of holes (for example, a bearing or a flange), it is usually necessary to lubricate the holes, apply an anti-corrosion agent, etc.

[0003] For example, in the field of wind power, the quality of the anti-corrosion coating inside the mounting hole of the variable pitch bearing is the key to whether the variable pitch bearing has good reliability. During the operation of the wind turbine, if the anti-corrosion coating in the mounting hole fails, it may cause rust in the mounting hole and endanger the safe operation of the wind turbine. At present, there are two main types of anti-corrosion coating materials in the mounting hole of the variable pitch bearing: paint and anti-rust oil. For paint, it can be sprayed or brushed. However, for anti-rust oil, brushing is usually used because spraying can easily cause splashing of anti-rust oil. However, when brushing anti-rust oil, it is generally done manually in sequence, brushing only one hole at a time, which has the problem of slow brushing efficiency and difficult to control brushing quality, resulting in poor brushing quality.

[0004] Therefore, it is necessary to provide a painting device that can improve painting efficiency and control painting quality. Summary of the invention

[0041] like Figures 1 to 9 As shown, the painting device 100 may include: a painting portion, including at least one painting brush head 7 and at least one rotating shaft 6 respectively connected to the painting brush head 7; a reciprocating motion mechanism 10; and a driving portion, including a driving motor 14. The driving motor 14 can drive the reciprocating motion mechanism 10 and the painting portion through a first transmission member 21 to make the reciprocating motion mechanism 10 reciprocate and make at least one painting brush head 7 rotate while reciprocating.

[0042] In the present disclosure, the coating device 100 may be a device capable of coating various fluids (e.g., anti-rust oil, adhesive, paint, etc.) to a portion to be coated. In particular, in the present embodiment, the coating device 100 may be a device installed on the end surface of the inner ring or outer ring of the pitch bearing 1 to coat the anti-rust oil in the mounting hole of the pitch bearing 1, but is not limited thereto. For example, the coating device 100 may also be used for a flange assembly including a plurality of periodically arranged holes.

[0043] The painting head 7 can be any component capable of painting, including but not limited to a brush (such as Figure 5 and Figure 6 ), steel wool, etc. The material of the brush head 7 is not particularly limited. For example, the material of the brush head 7 can be at least one of natural hair (for example, wool, horse hair, sisal, pig bristle, plant fiber (wood fiber, bamboo fiber, etc.)) and artificial fiber (nylon, polyethylene terephthalate (PET), polybutylene terephthalate (PBT)). For example, when applying anti-rust oil, the material of the brush head 7 can be plant fiber material, but is not limited thereto.

[0044] The rotating shaft 6 may be connected to the brush head 7. Specifically, the brush head 7 may be formed with a threaded hole for connecting with the rotating shaft 6, and the rotating shaft 6 may be threadedly connected to the threaded hole of the brush head 7, but the present disclosure is not limited thereto. For example, the rotating shaft 6 may also be formed integrally with the brush head 7.

[0045] The reciprocating mechanism 10, as a mechanism for performing reciprocating motion, can adopt a worm gear mechanism, a hydraulic reciprocating mechanism, a rack mechanism, a lead screw, etc. In the above specific structural form, the rotating shaft 6, the rotating motion of the brush head 7 and the reciprocating mechanism 10 can share a driver through a transmission component, or a driver, such as a motor, can be separately provided for the rotating shaft 6 and the brush head 7 to drive the rotating shaft 6 and the brush head 7 to rotate. As a preferred mode, the present embodiment adopts a lead screw as the reciprocating mechanism 10, and is connected to the rotating shaft 6 through a transmission component.

[0046] In this case, since the brush head 7 can rotate while reciprocating, it can be extended into a location such as a hole waiting to be painted to perform a painting operation, and after completing the painting operation of the current painting location, the brush device 100 can be moved to other locations to be painted to continue the painting operation.

[0047] The painting device 100 according to the exemplary embodiment of the present disclosure may also include a fluid supply unit. The fluid supply unit includes a fluid pump 24 and a fluid pump drive wheel 23 connected to the fluid pump 24, and the drive motor 14 drives the fluid pump drive wheel 23 through the second transmission member 22. However, the present disclosure is not limited to this. For example, the fluid to be painted can be applied to the painting head 7 in advance and then the painting operation can be performed.

[0048] The fluid pump 24 may be provided with a fluid inlet and a fluid outlet, the fluid inlet may be connected to a container containing a fluid (e.g., rust-proof oil, paint) to be brushed, and the fluid outlet may be connected to the fluid dispenser 20 described below through a delivery pipeline. The delivery pipeline is not particularly limited as long as it can perform fluid delivery. For example, the delivery pipeline may be a metal pipe, a rubber pipe, etc. The fluid pump drive wheel 23 is driven by the drive motor 14 through the second transmission member 22, and the fluid pump 24 is driven by the fluid pump drive wheel 23 to perform the delivery operation of the above-mentioned fluid. Here, the fluid pump drive wheel 23 may be connected to the input shaft of the fluid pump 24 in an interference fit manner, but is not limited thereto. In addition, the fluid pump drive wheel 23 may be provided with a ratchet mechanism to drive the fluid pump 24 in one direction. For example, the ratchet mechanism may be built into the fluid pump drive wheel 23.

[0049] The painting device 100 according to the exemplary embodiment of the present disclosure may further include: a first support portion 3, provided with a first through hole 310 through which at least one rotating shaft 6 passes and a groove portion 320 to which one end of the reciprocating mechanism 10 is connected; a second support portion 8; provided below the first support portion 3 and provided with an opening portion 820, the opening portion 820 being connected to the other end of the reciprocating mechanism 10; and a track portion 11, connected between the first support portion 3 and the second support portion 8 and including a track capable of reciprocating motion. The reciprocating mechanism 10 drives the track and the first support portion 3 to reciprocate together when reciprocating.

[0050] The painting device 100 according to the exemplary embodiment of the present disclosure may further include: a third support portion 9 disposed above the first support portion 3 and connected to the first support portion 3 , and the third support portion 9 is provided with a third through hole 910 for installing at least one rotating shaft 6 .

[0051] The first support part 3, the second support part 8, and the third support part 9 can be components that can play a supporting role, including but not limited to plates and beams. The materials of the first support part 3, the second support part 8, and the third support part 9 can be metal, plastic, etc., as long as they can meet the support requirements. The materials of the first support part 3, the second support part 8, and the third support part 9 can be the same or different from each other.

[0052] The groove portion 320 of the first support portion 3 may be provided with a connection member (eg, a bearing) for connecting to one end of the reciprocating mechanism 10 .

[0053] The first support portion 3 can be connected to the third support portion 9 through a first fastener 16. The first support portion 3 can be connected to the track of the track portion 11 through a second fastener 12, and the track portion 11 can be connected to the second support portion 8 through a third fastener 17 and a fourth fastener 18, and one end of the reciprocating mechanism 10 (for example, a lead screw) can be connected to a connector (for example, a bearing 90) in the groove portion 320 of the first support portion 3, and the other end of the reciprocating mechanism 10 can be connected to the opening portion 820 of the second support portion 8 to form a kinematic pair (for example, a threaded pair). Therefore, the first support portion 3 can reciprocate with the track of the track portion 11 through the drive of the reciprocating mechanism 10. In the case where the reciprocating mechanism 10 is a structure other than a lead screw, the reciprocating mechanism 10 can still be arranged between the first support portion 3 and the second support portion 8, and the connection relationship between them can be set accordingly by a person skilled in the art according to actual conditions. The fifth fastener 15 and the sixth fastener 19 can respectively mount the drive motor 14 and the fluid pump 24 on the lower surface of the first support portion 3 (such as Figure 2Here, the first fastener 16, the second fastener 12, the third fastener 17, the fourth fastener 18, the fifth fastener 15 and the sixth fastener 19 may be components such as bolts, studs, screws, pins, rivets, etc., but are not limited thereto. The number of the first fastener 16, the second fastener 12, the third fastener 17 and the fourth fastener 18 may be determined according to actual needs.

[0054] The number of the first through hole 310 provided on the first support portion 3, the second through hole 810 (fluid outlet) provided on the second support portion 8 to be described later, the third through hole 910 provided on the third support portion 9, and the rotating shaft 6 may be equal to the number of the brush heads 7, and may be determined according to the number of the brush heads 7. In the coating device 100 according to the exemplary embodiment of the present disclosure, the number of the brush heads 7 is 5, but is not limited thereto. For example, the number of the brush heads 7 may be one or more (for example, at least three). In the case where the number of the brush heads 7 is 5, the number of the first through hole 310 provided on the first support portion 3, the second through hole 810 provided on the second support portion 8, the third through hole 910 provided on the third support portion 9, and the rotating shaft 6 may all be 5. The number of the brush heads 7 may be determined according to actual needs.

[0055] In the case of multiple brush heads 7, multiple parts to be painted can be painted at the same time, so as to avoid painting only one part to be painted at one time, so as to improve the painting efficiency. Moreover, since the brush head 7 can reciprocate, the painting process can be repeated, so as to improve the painting quality. In addition, for the part to be painted such as a hole, the brush head 7 can reciprocate and extend into the inside of the part to be painted for painting, so as to avoid splashing of the painting fluid, so as to improve the painting quality.

[0056] In the case of at least three coating heads 7, the arrangement of the coating heads 7 can be set accordingly according to the form of the part to be coated. For example, the coating heads 7 can be arranged in a straight line form, a broken line form or a curved line form. For a pitch bearing, they can be arranged in an arc form.

[0057] The first through hole 310 may be provided with a bearing 5, and the third through hole 910 may be provided with a bearing 4. At least one rotating shaft 6 may be connected to the bearing 5 provided in the first through hole 310, and may be connected to the bearing 4 provided in the third through hole 910, respectively.

[0058] However, the present disclosure is not limited to the above-mentioned connection method. For example, the rotating shaft 6 can also be connected to the first through hole 310 of the first support part 3 and the third through hole 910 of the third support part 9 respectively by a threaded connection. Alternatively, the first through hole 310 of the first support part 3 and the third through hole 910 of the third support part 9 can be a light hole, and the rotating shaft 6 can pass through the first through hole 310 of the first support part 3 and the third through hole 910 of the third support part 9 in a transition fit manner, and in this case, the rotating shaft 6 can be connected to the first support part 3 while rotating so as to reciprocate with the first support part 3 under the drive of the reciprocating motion mechanism 10.

[0059] As an example, the reciprocating mechanism 10 may be a lead screw. In this case, one end of the lead screw may be connected to a bearing 90 disposed in a groove portion 320 of the first support portion 3, and the other end of the lead screw may be threadedly connected to an opening portion 820 disposed in the second support portion 8 to form a rotation pair, and the rotating shaft 6 of the brushing portion may be connected to a bearing 5 disposed in a first through hole 310 of the first support portion 3 and a bearing 4 disposed in a third through hole 910 of the third support portion 9. In this case, the brushing head 7 of the brushing portion may be located above the second support portion 8 when the drive motor 14 is not working.

[0060] The reciprocating mechanism 10 can reciprocate through the first transmission member 21 under the drive of the driving motor 14, thereby driving the first support part 3 to reciprocate along the path defined by the track part 11. The first transmission member 21 is also in contact with the rotating shaft 6 to drive the rotating shaft 6 to rotate. Since the rotating shaft 6 is connected with the brush head 7, the brush head 7 also rotates with the rotating shaft 6, and since the rotating shaft 6 is connected with the bearing 5 provided in the first through hole 310 of the first support part 3 and the bearing 4 provided in the third through hole 910 of the third support part 9, while the first support part 3 reciprocates, the rotating shaft 6 and the brush head 7 also reciprocate along the path defined by the track part 11 following the first support part 3. Here, since the first support part 3 and the third support part 9 are connected to each other, the third support part 9 can also reciprocate following the first support part 3. However, according to an exemplary embodiment of the present disclosure, the third support part 9 may not be provided. In this case, the bearing 4 and the third through hole 910 can be omitted, thereby simplifying the structure of the brushing device 100 and reducing the cost.

[0061] The first transmission member 21 and the second transmission member 22 may be any one of a belt, a gear and a chain, and the first transmission member 21 contacts one end of the reciprocating mechanism 10 and at least one rotating shaft 6, and the second transmission member 22 contacts the fluid pump driving wheel 23. The fluid pump driving wheel 23 may be connected to the input shaft of the fluid pump 24 by interference fit, thereby driving the fluid pump 24 to work.

[0062] When the first transmission member 21 and the second transmission member 22 are belts, the belts may be flat belts, V-belts, multi-V belts, synchronous belts, etc. known to those skilled in the art, but are not limited thereto, and a pulley 61 matching the above-mentioned belts may be provided on the rotating shaft 6.

[0063] like Figure 6 As shown in , the first transmission member 21 may contact one end of the reciprocating mechanism 10 and the pulley 61 disposed on the rotating shaft 6 in sequence. The first transmission member 21 may contact the first portion and the second portion of the pulley 61 alternately in a bent form. Here, as shown in Figure 6 As shown in , the first part and the second part of the pulley 61 are divided by a virtual plane passing through the axis of the rotating shaft 6. The part of the pulley 61 on one side of the virtual plane can be called the first part, and the part of the pulley 61 on the other side of the virtual plane can be called the second part. In this case, since the first transmission member 21 contacts different parts of the pulley 61, slippage and the like are avoided, force and torque can be better transmitted, thereby improving transmission efficiency.

[0064] As an example, the bearings 90 may be arranged in pairs, wherein one of the pair of bearings 90 may be arranged in the groove portion 320 of the first support portion 3, and the other of the pair of bearings 90 may be arranged above the one of the bearings 90 and symmetrically arranged relative to the one end of the reciprocating mechanism 10. Here, the one end of the reciprocating mechanism 10 may be a rotating wheel arranged on the end of the reciprocating mechanism 10 to be connected to the first support portion 3, and the first transmission member 21 may contact and cooperate with the rotating wheel to drive the reciprocating mechanism 10.

[0065] The painting device 100 according to the exemplary embodiment of the present disclosure also includes a fluid dispenser 20. The fluid dispenser 20 is disposed on the second support portion 8, and one end of the fluid dispenser 20 can be connected to the fluid pump 24, and the other end of the fluid dispenser 20 can be connected to a second through hole 810 (fluid discharge port) disposed on the second support portion 8 through a delivery pipe, and the portion to be painted (for example, the mounting hole of the pitch bearing 1) and the second through hole 810 are aligned with each other in a first direction (based on the downward direction of the drawing). Here, the fluid delivered from the fluid dispenser 20 can be delivered to the vicinity of the second through hole 810 of the second support portion 8 (for example, above a side edge of the second through hole 810) through a delivery pipe, as shown in FIG. Figure 8 Although Figure 8Only the delivery pipeline near the second through hole 810 is shown, but this is only for illustration. Those skilled in the art know that a delivery pipeline is provided between the fluid distributor 20 and the second through hole 810 to deliver the fluid to the vicinity of the second through hole 810, and those skilled in the art can design the delivery pipeline according to actual conditions. For example, the delivery pipeline can be connected to the fluid distributor 20 and can extend directly to the vicinity of the second through hole 810.

[0066] When the brushing device 100 is used for painting, the driving motor 14 can be started to rotate forward, and the brush head 7 can be driven by the reciprocating mechanism 10 and the first transmission member 21 to rotate while moving along the first direction to the part to be painted. Then, after the brush head 7 completes the painting operation, the driving motor 14 can be started to rotate backward, so that the brush head 7 leaves the part to be painted along the second direction. Here, before the driving motor 14 is driven to rotate forward, the brushing device 100 can be installed to the part to be painted. In addition, the first direction and the second direction can be opposite to each other.

[0067] In this case, the fluid to be applied (e.g., rust-proof oil, paint, etc.) can be applied to the brush head 7 in advance, and then the brush head 7 is rotated while moving to the part to be applied to perform the application. After the application is completed, the drive motor 14 can be started to reverse, so that the brush head 7 leaves the part to be applied.

[0068] The coating method of the coating device 100 according to the present disclosure will be described below by taking the coating device 100 being installed on the pitch bearing 1 to apply anti-rust oil to the mounting hole of the pitch bearing 1 as an example.

[0069] First, the second support portion 8 of the brushing device 100 is placed and fixed on the end face of the inner ring or outer ring of the pitch bearing 1, and the brush head 7, the second through hole 810 of the second support portion 8 and the mounting hole to be brushed with anti-rust oil are aligned with each other in the first direction. Here, the number of the second through holes 810 can be determined according to the number of mounting holes to be brushed with anti-rust oil, and can be changed according to design requirements. At this time, the drive motor 14 is not started, and the brush head 7 of the brushing part can be located above the second support portion 8.

[0070] Then, the drive motor 14 is started to rotate forward, and the drive motor 14 drives the drive wheel 13 and the first transmission member 21 to rotate, and then drives the reciprocating mechanism 10 and the rotating shaft 6 through the first transmission member 21. Driven by the drive motor 14, the rotating shaft 6 can rotate, and the movement of the reciprocating mechanism 10 in the first direction (downward movement) drives the first support part 3 and the rotating shaft 6 connected to the first support part 3 to move in the first direction along the path defined by the track part 11 at the same time, thereby driving the brush head 7 to move in the first direction to the mounting hole of the pitch bearing 1. In other words, the brush head 7 can move in the first direction to the mounting hole of the pitch bearing 1 while rotating. In the case where the reciprocating mechanism 10 is a lead screw, one end of the lead screw can be connected to the bearing 90 in the groove 320 of the first support part 3, and the other end of the lead screw is threadedly connected to the opening 820 of the second support part 8 to form a rotation pair, so that the first support part 3 and the rotating shaft 6 connected to the first support part 3 can move along the track in the track part 11 in the first direction at the same time, thereby driving the brush head 7 to move in the first direction. In other words, the brush head 7 can move in the first direction to the mounting hole of the pitch bearing 1 while rotating.

[0071] When the driving motor 14 rotates forward to drive the driving wheel 13, the second transmission member 22 can be driven to rotate, thereby driving the fluid pump driving wheel 23 to drive the fluid pump 24 to work. The fluid pump 24 can be provided with a fluid inlet and a fluid outlet, the fluid inlet can be connected to a container containing the fluid to be brushed (for example, anti-rust oil, paint), and the fluid outlet can be connected to the fluid distributor 20 through a delivery pipe, so when the fluid pump 24 is working, the fluid is transported from the container containing the fluid to be brushed (for example, anti-rust oil, paint) to the fluid pump 24, from the fluid pump 24 to the fluid distributor 20 through the delivery pipe, and then from the fluid distributor 20 to the second through hole 810 of the second support part 8 through the delivery pipe. The fluid flows out from the end of the delivery pipe (or the oil nozzle provided on the end of the delivery pipe) and is then applied to the rotating brush head 7. In this case, the brush head 7 moves along the first direction into the mounting hole of the pitch bearing 1 and brushes the fluid on the wall surface of the mounting hole of the pitch bearing 1.

[0072] After the coating head 7 completes the coating operation, the driving motor 14 is reversed, so that the reciprocating mechanism 10 drives the first support part 3 and the rotating shaft 6 connected to the first support part 3 to move (upward) along the path defined by the track part 11 in the second direction through the kinematic pair formed by the reciprocating mechanism 10 and the second support part 8 (for example, when the reciprocating mechanism 10 is a lead screw, the lead screw and the second support part 8 form a spiral pair), and the coating head 7 is moved out of the mounting hole of the pitch bearing 1. In the process of the coating head 7 moving along the first direction into the mounting hole of the pitch bearing 1, the fluid can be evenly coated on the wall surface of the mounting hole of the pitch bearing 1 through the rotational movement of the coating head 7, and in the process of the coating head 7 moving out of the mounting hole of the pitch bearing 1 in the second direction, the coating head 7 can further coat the wall surface of the mounting hole to improve the coating quality.

[0073] Optionally, in the process of the brush head 7 moving out of the mounting hole of the pitch bearing 1 along the second direction, the brush head 7 may be set not to brush the wall surface of the mounting hole. Here, since the fluid pump driving wheel 23 is provided with a ratchet mechanism, when the driving motor 14 is reversed, the fluid pump 24 does not work, and the brush head 7 does not perform the brushing operation. After the brush head 7 is completely moved out of the mounting hole of the pitch bearing 1, the brushing device 100 can be removed and installed at the mounting hole of the next set of pitch bearings 1, and the above operation can be repeated.

[0074] Here, the operation method of the brushing device 100 according to the present disclosure is described by taking the example of the brushing device 100 being installed on the pitch bearing 1 to apply anti-rust oil to the mounting hole of the pitch bearing. However, those skilled in the art will know that the brushing device 100 according to the present disclosure can also be applied to other application scenarios, for example, brushing components with multiple holes such as flanges.

[0075] As described above, the painting device according to the exemplary embodiment of the present disclosure may improve painting efficiency and may improve painting quality at the same time.

[0076] While the present disclosure has been described in detail with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the claims.
