The length of the rotor shaft body is less than the length of the rotor shaft rod, and the rotor shaft rod extends from both ends of the rotor shaft body; the painting unit is used to paint the rotor shaft body.

[0011] In one embodiment, the moving mechanism is located above the moving part, and the moving mechanism includes a hand support part and an up-and-down moving part connected to the hand support part, wherein:

[0012] The hand support component is used to support the rotor shaft rods at both ends of the rotor.

[0013] The up-and-down moving component is used to: drive the hand support component to move downward before painting, and move the rotor downward to the position where the rotor shaft body contacts the moving component through the hand support component; drive the hand support component to move upward after painting, and move the rotor upward to the position where the rotor shaft body does not contact the moving component through the hand support component.

[0014] In one embodiment, the moving component includes two rolling rollers arranged side by side, and the rotation directions of the two rolling rollers are the same. During painting, the rotor is moved between the two rolling rollers and the rotor shaft body contacts the two rolling rollers, and the two rolling rollers are used to drive the rotor shaft body to rotate when rotating.

[0015] In one embodiment, the moving component further includes a plurality of evenly distributed rollers sleeved on each rolling roller.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0033] An embodiment of the present utility model provides a rotor painting device. Refer to Figure 1 and Figure 2 . The rotor painting device 10 includes at least one painting unit, and each painting unit includes:

[0034] A box body 11;

[0035] A movable hatch 12, arranged on the box body 11. By moving the movable hatch 12, the box body 11 can be brought into an open state or a closed state. In the open state, the rotor can be placed in the box body 11 or taken out from the box body 11, and in the closed state, the rotor is painted;

[0036] A moving mechanism, arranged in the box body 11, for driving the rotor to move to a position in contact with the moving part before painting and driving the rotor to move to a position not in contact with the moving part after painting;

[0037] A paint tank 16, arranged in the box body 11, and paint is provided in the paint tank 16;

[0038] A moving part, arranged in the paint tank 16, for driving the rotor in contact with the moving part to rotate and bringing the paint in the paint tank 16 to the rotor when the rotor rotates, so as to paint the rotor.

[0039] It can be understood that the box body 11 has an opening, and the movable hatch 12 is arranged on the box body 11. By moving the movable hatch 12, the movable hatch 12 can form a closed space with the box body 11, so that the box body 11 enters the closed state; by moving the movable hatch 12, the opening of the box body 11 can also be exposed, so that the box body 11 enters the open state.

[0040] Specifically, move the movable hatch 12 to make the box body 11 in the open state. At this time, place the rotor in the box body 11. Then move the movable hatch 12 to make the box body 11 enter the closed state, and then paint the rotor. After painting is completed, move the movable hatch 12 to make the box body 11 change to the open state, and take out the painted rotor from the box body 11. Thus, the painting work is completed.

[0041] Among them, the rotor is specifically placed on a moving mechanism inside the box body 11, so that the moving mechanism can drive the rotor to move. When the rotor moves to a position in contact with the moving part, the moving mechanism stays for a period of time, that is, it does not drive the rotor to move its position within a period of time. During this period of time, the moving part drives the rotor to rotate through the frictional force between the moving part and the rotor. During the rotation of the rotor, the moving part brings the paint in the paint tank 16 onto the rotor, thereby realizing painting the rotor. After the painting is completed, the moving mechanism drives the rotor to move to a position where it cannot be contacted by the moving part, and specifically, it can return to the original initial position, and the rotor waits to be taken out.

[0042] Among them, paint is provided in the paint tank 16, and the moving part is arranged in the paint tank 16. Therefore, the moving part will also be immersed in the paint. Therefore, when the rotor is in contact with the moving part and rotates driven by the moving part, the paint will be brought onto the surface of the rotor.

[0043] Among them, the movement of the moving part and the moving mechanism inside the box body 11 can be driven and controlled by a controller, or manually driven and controlled by a person located outside the box body 11 through a transmission mechanism. Therefore, there are various ways to realize the movement of the moving part and the moving mechanism inside the box body 11, and it is not necessarily necessary to rely on the control program of the controller to achieve it.

[0044] Among them, referring to Figure 3 , the rotor may include a rotor shaft rod 21 and a rotor shaft body 22 sleeved on the rotor shaft rod 21. The length of the rotor shaft body 22 is less than the length of the rotor shaft rod 21, and the rotor shaft rod 21 extends from both ends of the rotor shaft body 22; the painting unit is used to paint the rotor shaft body 22.

[0045] Among them, the rotor shaft body 22 is usually pressed from silicon steel sheets, and the silicon steel sheets need to be protected by paint.

[0046] That is to say, the rotor may include a rotor shaft rod 21 and a rotor shaft body 22. The rotor shaft rod 21 and the rotor shaft body 22 are processed separately and then assembled together. Specifically, the length of the rotor shaft body 22 is smaller than the length of the rotor shaft rod 21, but the thickness of the rotor shaft body 22 is larger than the thickness of the rotor shaft rod 21. The rotor shaft body 22 is sleeved on the rotor shaft rod 21, and the rotor shaft rod 21 extends from both ends of the rotor shaft body 22.

[0047] It can be seen that the box body 11 is enclosed during painting, which can effectively prevent the diffusion of pungent odors. Before painting, the moving mechanism drives the rotor to move to a position in contact with the moving part. At this time, the moving part drives the rotor to rotate, so that the paint in the paint pool 16 is brought onto the rotor to achieve painting. After painting, the moving mechanism drives the rotor to move to a position not in contact with the moving part before painting, which can improve the automation degree of painting, reduce personnel participation, and further reduce the impact of pungent odors on personnel. Since the moving part drives the rotor to rotate, as long as the moving part drives the rotor to rotate smoothly, problems such as paint leakage and unevenness can be reduced, that is, the utility model can ensure that the rotor can evenly apply the paint film and ensure the product quality.

[0048] In one embodiment, the moving mechanism is located above the moving part. The moving mechanism includes a hand - holding part 13 and a vertical moving part 14 connected to the hand - holding part 13, where:

[0049] The hand - holding part 13 is used to hold the rotor shaft rods 21 at both ends of the rotor;

[0050] The vertical moving part 14 is used to: drive the hand - holding part 13 to move downward before painting, and through the hand - holding part 13, move the rotor downward to a position where the rotor shaft body 22 contacts the moving part; drive the hand - holding part 13 to move upward after painting, and through the hand - holding part 13, move the rotor upward to a position where the rotor shaft body 22 is not in contact with the moving part.

[0051] That is to say, the moving mechanism is above the moving part. The moving part can drive the rotor to move downward, so that the rotor contacts the moving part. The moving part can drive the rotor to move upward, so that the rotor changes from a contact state with the moving part to a non - contact state.

[0052] Among them, the moving mechanism includes a hand - holding part 13 and a vertical moving part 14. As the name implies, the hand - holding part 13 is similar to a person's hands and can hold the objects placed on it. The function of the hand - holding part 13 is to hold the rotor shaft rods 21 extending from both ends of the rotor shaft body 22. Specifically, at the beginning, the rotor is placed on the moving mechanism in the box body 11. In fact, the rotor shaft rods 21 extending from both ends of the rotor shaft body 22 are placed on the hand - holding part 13, which can not only hold the rotor shaft rods 21 but also does not affect the rotation of the rotor shaft body 22. Whether the rotor is moving up and down or the rotor shaft body 22 of the rotor is rotating for painting, both ends of the rotor shaft rod 21 are always held on the hand - holding part 13. During painting, the rotor shaft rod 21 is held by the hand - holding part 13, and the rotor shaft body 22 contacts the moving part. Therefore, the moving part can drive the rotor shaft body 22 to rotate, and the rotor shaft rod 21 will not move or rotate.

[0053] Among them, the up-and-down moving component 14 can be implemented by a cylinder. The hand-supporting component 13 is fixedly connected to the moving end of the cylinder. In this way, when the cylinder is working, the moving end moves up and down, thereby driving the hand-supporting component 13 to move up and down.

[0054] Specifically, after the rotor is placed on the hand-supporting component 13 in the box body 11, before formal painting, the up-and-down moving component 14 drives the hand-supporting component 13 to move downward. When the rotor shaft body 22 touches the moving component, the up-and-down moving component 14 stops driving the hand-supporting component 13 to move, that is, it stays for a period of time. During this period of time, the rotor shaft body 22 rotates along with the moving component, and the moving component brings the paint in the paint pool 16 to the rotor shaft body 22 to achieve painting. After painting is completed, the up-and-down moving component 14 drives the hand-supporting component 13 to move upward, and the rotor shaft body 22 moves upward along with it and cannot touch the moving component. When the up-and-down moving component 14 drives the hand-supporting component 13 back to the initial position, wait for the rotor to be taken out.

[0055] In one embodiment, the moving component may include two rollers 15 arranged side by side. The two rollers 15 rotate in the same direction. When painting, the rotor is moved between the two rollers 15 and the rotor shaft body 22 contacts the two rollers 15. The two rollers 15 are used to drive the rotor shaft body 22 to rotate when rotating.

[0056] That is to say, the moving component includes two rollers 15. The two rollers 15 are arranged side by side and rotate in the same direction. After the rotor is moved between the two rollers 15, the rotor shaft body 22 contacts the surfaces of the two rollers 15. During the rotation of the two rollers 15, the rotor shaft body 22 is driven to rotate by friction, thereby achieving painting.

[0057] Furthermore, the moving component may further include a plurality of evenly distributed rollers sleeved on each roller 15. When painting, the rotor shaft body 22 contacts the rollers of the two rollers 15; the rollers are used to rotate under the drive of the roller 15 to which they belong to drive the rotor shaft body 22 to rotate.

[0058] For example, 4 rollers are sleeved on each roller 15, and there are a total of 8 rollers on the two rollers 15. The rotor shaft body 22 specifically contacts these rollers on the two rollers 15. Each roller 15 drives its own roller to rotate, and the rollers of the two rollers 15 drive the rotor shaft body 22 to rotate. Since the moving component is immersed in the paint pool 16 and a part of the rotor shaft body 22 is also immersed in the paint pool 16, the entire rotor shaft body 22 will be painted as the rotor shaft body 22 rotates.

[0059] In one embodiment, each painting unit may further include:

[0060] A heating component for heating the paint tank 16 so that the temperature of the paint in the paint tank 16 is maintained within a preset range, and the paint does not solidify within the preset range.

[0061] That is to say, the paint tank 16 is heated by the heating component, so that the temperature of the paint in the paint tank 16 is maintained within a certain range, so that the paint will not solidify, and thus the rotors can be painted one by one continuously.

[0062] Wherein, the preset range is a temperature range that is low temperature but ensures that the paint does not solidify.

[0063] In one embodiment, each painting unit may further include:

[0064] A controller for controlling the movement of the movable hatch 12 after the rotor is placed in the box body 11 to make the box body 11 enter a closed state; controlling the movement of the moving component; controlling the moving mechanism to move the rotor downward to a position in contact with the moving component, and after staying for a first period of time, controlling the moving mechanism to move the rotor upward to a position not in contact with the moving component.

[0065] That is to say, after the rotor is placed in the box body 11, the movement of the movable hatch 12 is controlled by the controller to close the box body 11, then the movement of the moving component is controlled, and the moving mechanism is controlled to drive the rotor to move downward so that the rotor contacts the moving component, and then the moving mechanism is controlled to stay for a certain time. During this period, the moving component will drive the rotor to rotate, so that the rotor is painted. Then the controller controls the moving mechanism to drive the rotor to move upward and return to the initial position. The above process is the control process of the controller, which makes the automation degree of rotor painting higher. This control process is actually very simple and can be achieved only with a few common control instructions, without the need for professional developers to develop a control program.

[0066] Furthermore, in an actual scenario, the control of each component may also be realized without a controller. For example, the movable hatch 12 can be manually moved by a person to close and open. The person outside the box body 11 manually drives the movement of the moving component through a transmission mechanism, and can also manually drive the up and down movement of the rotor by the moving mechanism through the transmission mechanism. Therefore, the controller is not an essential component of the rotor painting device 10.

[0067] In one embodiment, each painting unit may further include:

[0068] The sensor is disposed inside the box body 11 and is configured to sense whether the rotor is placed on the hand support member 13, and notify the controller to perform control work when it senses that the rotor is placed on the hand support member 13.

[0069] That is to say, a sensor is disposed inside the box body 11 to sense whether the rotor is placed on the hand support member 13 and whether the rotor on the hand support member 13 is taken away. When it senses that the rotor is placed on the hand support member 13, it notifies the controller, thereby triggering the control work of the controller, which makes the automation degree of rotor painting higher.

[0070] In one embodiment, each painting unit may further include:

[0071] The robotic arm is configured to place the rotor on the hand support member 13 inside the box body 11 before painting or take out the rotor from the hand support member 13 inside the box body 11 after painting.

[0072] That is to say, the robotic arm is used to place the rotor on the hand support member 13 inside the box body 11 before painting, and after painting, the robotic arm is used to take out the rotor from the hand support member 13 and place it at a predetermined position outside the box body 11.

[0073] It can be seen that by using the robotic arm to pick up and place the rotor, not only the mechanization degree is improved, but also the safety of manual picking and placing is improved.

[0074] In the prior art, after the truss line processes the rotor, the rotors need to be centrally collected and then transported to the manual station for shaft surface painting, which wastes production efficiency and increases the labor cost of transportation. During the centralized transportation of the rotor shafts, it is extremely easy to cause bumps and scratches, thereby generating quality problems. Repairing the shaft surfaces of the rotors with quality problems wastes labor costs. In the present utility model, the rotor painting device 10 can be disposed on the side of the rotor processing unit. In this way, after the rotor is processed, the processed rotor can be directly placed inside the box body 11 by using the robotic arm. This not only reduces the labor cost of transportation, but also improves production efficiency, and avoids bumps and scratches caused by transportation, that is, avoids quality problems caused by transportation, and there is no need to repair because of this problem, thus saving labor costs.

[0075] In one embodiment, referring to Figure 1 and Figure 2 , the number of the painting units is 2, and the paint colors in the paint pools 16 of the two painting units are different.

[0076] For example, the paint in the paint tank 16 of a painting unit is red, and the rotor shaft body 22 can be painted red through this painting unit. The paint in the paint tank 16 of another painting unit is cyan, and the rotor shaft body 22 can be painted cyan through this painting unit.

[0077] It can be seen that by setting up two painting units, different needs of users can be met.

[0078] It is understandable that manual painting is affected by factors such as the environment and experience, resulting in missed painting or uneven paint film on the rotor shaft body 22, thus forming a quality risk for the product. Moreover, the paint has a pungent smell, posing a potential personal safety risk to the operators. To solve the above problems, in the prior art, in the quality inspection link, the painted rotor shaft body 22 is inspected for quality, the paint nodules are polished, and the missed painting parts are repainted. This method increases the production cost. The operators wear protective masks to prevent inhalation of irritating gases.

[0079] In the present utility model, the rotor painting device 10 is used to paint the rotor shaft body 22. Since it is a mechanized operation, it can avoid the influence of human factors, reduce problems such as missed painting and uneven painting, improve the product quality, and does not require additional personnel to polish the paint nodules and repaint the missed painting parts, thus reducing the production cost. Moreover, since the painting operation is carried out inside the box body 11 and the box body 11 is in a closed state, the safety of the operators outside the box body 11 can be improved compared with the method of wearing masks.

[0080] The rotor painting device provided by the present utility model has the following beneficial effects:

[0081] (1) The rotor painting device can be arranged at the end of the rotor truss line. After the rotor is processed, it is grabbed by the robotic arm and placed inside the box body, reducing the transfer time and labor cost and improving the production efficiency.

[0082] (2) The rotor painting device adopts the double-roller oil immersion rolling paint technology to ensure the stable rotation of the rotor on the double rollers, so as to ensure that the rotor shaft body 22 can be evenly coated with the paint film and ensure the product quality.

[0083] (3) The paint tank is heated to ensure that the paint does not solidify, and at the same time, the viscosity of the paint during painting can be controlled, so as to achieve the effect of controlling the paint film thickness.

[0084] (4) When painting, the box body is in a closed state, effectively preventing the diffusion of pungent smell. Since the automatic degree of painting is improved by the rotor painting device and the personnel participation is reduced, the influence of the pungent smell on the personnel is further reduced.

[0085] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the key point of each embodiment is to illustrate the differences from other embodiments. In particular, for the apparatus embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and for the relevant parts, reference can be made to the corresponding descriptions in the method embodiments.

[0086] The specific implementation manners described above further elaborate on the purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above description is only the specific implementation manners of the present utility model and is not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solution of the present utility model shall be included in the protection scope of the present utility model.
