Abstract

The application discloses a light-weight high-efficiency energy-saving new energy vehicle motor paint dripping system, which comprises a clamping device, a clamping base, a mounting frame, an axis position driving device and a paint dripping execution device. The clamping device is used for clamping the outer side surface of a motor stator. The clamping device is installed on the clamping base. The top of the clamping base is rotatably installed on the mounting frame. The axis position driving device is installed on the mounting frame. The output end of the axis position driving device is connected to the bottom of the clamping base. The axis position driving device is used for turning over the motor stator on the clamping device by driving the clamping base. The motor stator can be turned over to a feeding station and a paint dripping station. The axial center line of the motor stator is parallel to the horizontal direction when the motor stator is at the feeding station. The light-weight high-efficiency energy-saving new energy vehicle motor paint dripping system solves the problem that the axial center line of the motor stator cannot be rotated relative to the horizontal direction due to the fact that the fixed frame can be relatively rotated around the axial center line of the mounting frame in the vertical direction in the prior art.

Description

Technical Field

[0001] This invention relates to a motor stator coating equipment, specifically to a lightweight, high-efficiency, and energy-saving new energy vehicle motor coating system. Background Technology

[0002] Chinese patent discloses a new energy motor stator paint dripping execution device with application number CN202423322339.1. This device includes: a fixed frame, a paint dripping mechanism, a clamping and positioning mechanism, a rotary drive mechanism, and an angle adjustment mechanism. The fixed frame is rotatably mounted on an external mounting frame, and the fixed frame is vertically positioned relative to the external mounting frame around its rotational axis. The clamping and positioning mechanism is mounted on the fixed frame for clamping the motor stator. The rotary drive mechanism is mounted on the fixed frame for driving the clamping and positioning mechanism and the motor stator to rotate. The paint dripping mechanism is mounted on the fixed frame for dripping paint onto the clamping and positioning mechanism from the motor stator.

[0003] Although the aforementioned new energy motor stator paint dripping device can clamp the motor stator and perform paint dripping, it still has the following drawbacks: because the axis of rotation of the fixed frame relative to the external mounting frame is in the vertical direction, the axis of rotation of the motor stator cannot rotate in the horizontal direction. As a result, the inner wall of the motor stator parallel to the axis cannot be dripped with paint, leading to a low degree of completion of the paint dripping work and low product quality. Summary of the Invention

[0004] This invention provides a lightweight, high-efficiency, and energy-saving paint dripping system for new energy vehicle motors, solving the problem in the prior art where the axis of rotation of the fixed frame relative to the external mounting frame is located in the vertical direction, causing the motor stator axis to be unable to rotate relative to the horizontal direction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a lightweight, high-efficiency, and energy-saving new energy vehicle motor paint dripping system, comprising: a clamping device, a clamping base frame, a mounting frame, an axis position driving device, and a paint dripping execution device. The clamping device is used to clamp the outer side of the motor stator. The clamping device is mounted on the clamping base frame, and the top of the clamping base frame is rotatably mounted on the mounting frame. An axis position driving device is mounted on the mounting frame, and the output end of the axis position driving device is connected to the bottom of the clamping base frame. The axis position driving device is used to drive the clamping base frame to rotate the motor stator on the clamping device. The motor stator can be rotated to the loading station and the paint dripping station. In the loading station, the centerline of the motor stator is parallel to the horizontal direction. At the paint dripping station, the angle between the motor stator axis and the horizontal direction is acute. A paint dripping actuator is installed at the mounting frame, and the output end of the paint dripping actuator is located next to the clamping device. The lightweight, high-efficiency, and energy-saving new energy motor paint dripping process is realized based on the aforementioned lightweight, high-efficiency, and energy-saving new energy vehicle motor paint dripping system. The lightweight, high-efficiency, and energy-saving new energy motor paint dripping process includes the following steps: S1, the motor stator is installed on the clamping device located at the loading station, at which time the clamping device can clamp the motor stator located at the loading station; S2, the axis position drive device drives the clamping base frame to rotate, so that the motor stator clamped by the clamping device rotates to the paint dripping station; S3, the paint dripping actuator drips paint onto the motor stator clamped by the clamping device.

[0006] Preferably, the clamping device is rotatably mounted on the clamping base, and the clamping base is equipped with a self-rotation drive device for driving the clamping device to rotate.

[0007] Preferably, the clamping device includes two fixed clamping parts and one elastic clamping part, the two fixed clamping parts and the elastic clamping part cooperating to clamp the outer side wall of the motor positioning.

[0008] Preferably, a pull-out actuator is installed on the mounting bracket, which is used to pull the elastic clamping part away from the two fixed clamping parts.

[0009] Preferably, in step S1, the clamping device needs to maintain the following state: the line connecting the positions of the two fixed clamping parts is parallel to the horizontal plane.

[0010] Preferably, the axis of rotation of the top of the clamping base relative to the mounting frame is parallel to the horizontal plane.

[0011] Preferably, step S4 is performed after step S3 is completed. Step S4 includes the following steps: the axis position drive device drives the clamping base frame to return to the loading station.

[0012] Preferably, step S4 also includes the following steps: the self-rotation drive device drives the clamping device to rotate until the clamping device rotates relative to the clamping base to the loading station, and the line connecting the positions of the two fixed clamping parts in the clamping device is parallel to the horizontal plane when the loading station is reached.

[0013] Preferably, there are at least two lightweight, high-efficiency, and energy-saving new energy vehicle motor paint spraying systems, and all lightweight, high-efficiency, and energy-saving new energy vehicle motor paint spraying systems are arranged in a row.

[0014] Compared to existing technologies, this invention has the following advantages: This application breaks away from the existing technology where the axis of rotation of the fixed frame relative to the external mounting frame is vertical. The design of the clamping base with its rotation axis parallel to the horizontal plane relative to the mounting frame makes it impossible to rotate the motor stator axis to an acute angle with the horizontal when the rotation axis is vertical. Furthermore, it makes it impossible to drip vertically onto the inner wall of the motor stator. This invention, by designing the rotation axis of the clamping base parallel to the horizontal plane relative to the mounting frame, enables the rotation of the motor stator axis to an acute angle with the horizontal, thus allowing vertically dripping paint to drip onto the inner wall of the motor stator. This ensures that the inner wall of the motor stator product meets the requirement for paint dripping, improving the quality of the motor stator product.

[0015] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figures 1 to 4 As shown, this invention discloses a lightweight, high-efficiency, and energy-saving new energy vehicle motor paint dripping system, comprising: a clamping device 1, a clamping base frame 2, a mounting frame 3, an axis position driving device 4, and a paint dripping execution device 5. The clamping device 1 is used to clamp the outer side of the motor stator. The clamping device 1 is mounted on the clamping base frame 2. The top of the clamping base frame 2 is rotatably mounted on the mounting frame 3. The axis position driving device 4 is mounted on the mounting frame 3. The output end of the axis position driving device 4 is connected to the bottom of the clamping base frame 2. The axis position driving device 4 is used to drive the clamping base frame 2 to rotate the motor stator on the clamping device 1. The motor stator can be rotated to a loading station and a paint dripping station. In the loading station, the axis of the motor stator is parallel to the horizontal direction. In the paint dripping station, the motor stator is rotated to a loading station and a paint dripping station. The angle between the centerline of the stator and the horizontal direction is acute; a paint dripping device 5 is installed at the mounting frame 3, and the output end of the paint dripping device 5 is located next to the clamping device 1; the lightweight, high-efficiency, and energy-saving new energy motor paint dripping process is realized based on the aforementioned lightweight, high-efficiency, and energy-saving new energy vehicle motor paint dripping system. The lightweight, high-efficiency, and energy-saving new energy motor paint dripping process includes the following steps: S1, the motor stator is installed on the clamping device 1 located at the loading station, at which time the clamping device 1 can clamp the motor stator located at the loading station; S2, the axis position driving device 4 drives the clamping base frame 2 to rotate, so that the motor stator clamped by the clamping device 1 rotates to the paint dripping station; S3, the paint dripping device 5 drips paint onto the motor stator clamped by the clamping device 1.

[0022] In this application, the axial position drive device 4 is a linear drive device. The output end of the axial position drive device 4 is hinged to the clamping base 2 via a hinge shaft. The clamping base 2 has a hinge hole through which the hinge shaft passes, and there is a certain gap between the hinge hole and the hinge shaft to ensure that the clamping base 2 can rotate when the output end of the axial position drive device 4 moves linearly. After the top of the clamping base 2 is hinged to the mounting frame 3, the clamping base 2 is selectively supported.

[0023] In this application, the clamping device 1 is rotatably mounted on the clamping base 2, and a self-rotation drive device 6 is mounted on the clamping base 2. The self-rotation drive device 6 is used to drive the clamping device 1 to rotate. Since it is necessary to drip paint on all parts of the inner wall of the motor stator, the clamping device 1 is designed to rotate relative to the clamping base 2. At the same time, the self-rotation drive device 6 drives the clamping device 1 to rotate, thereby automatically driving different positions of the motor stator clamped by the clamping device 1 to align with the output end of the paint dripping execution device 5, ensuring that paint can be dripped on all positions of the motor stator.

[0024] In this application, the clamping device 1 includes two fixed clamping parts 11 and one elastic clamping part 12, which cooperate to clamp the outer side wall of the motor positioning device. The clamping device 1 provides three clamping points, which are located at the two fixed clamping parts 11 and the elastic clamping part 12 respectively.

[0025] Optionally, the clamping device 1 further includes a clamping ring 13, which is rotatably mounted on the clamping base 2, and two fixed clamping parts 11 and an elastic clamping part 12 are installed at equal intervals on the clamping ring 13.

[0026] Optionally, the self-rotation drive device 6 includes: a gear ring 61, a drive gear, a gear set (not shown in the figure), and a self-rotation drive motor. The self-rotation drive motor is mounted on the mounting bracket 3. The output end of the self-rotation drive motor is connected to the input end of the gear set, and the output end of the gear set is connected to the drive gear. The drive gear meshes with the gear ring 61. The gear ring 61 is mounted on the clamping ring 13, and the outer wall of the gear ring 61 meshes with the drive gear. This realizes that the self-rotation drive motor drives the gear set to rotate, and the gear set drives the gear ring 61 to rotate through the drive gear.

[0027] To reduce the probability of paint dripping onto the gear ring 61 and to prevent the paint from affecting the smooth rotation of the gear ring 61 and the clamping ring 13, the surface of the fixed clamping part 11 that clamps the motor stator is the first clamping surface, and the surface of the elastic clamping part 12 that clamps the motor stator is the second clamping surface. There is an annular gap between the first clamping surface and the second clamping surface and the inner wall of the clamping ring 13, and the annular gap allows paint to drip.

[0028] In this application, in order to fully catch the paint and prevent it from dripping onto the ground, the bottom of the mounting frame 3 is equipped with a receiving groove 7. The mounting frame 3 has a window, and a guide structure 20 is provided on the inner wall of the window. The guide structure 20 guides the clamping ring 13 to rotate. When paint drips, it passes through the above-mentioned annular gap and the window and drips into the receiving groove 7, which can achieve the effect of 100% no paint on the working environment floor and ensure the cleanliness of the working environment.

[0029] To prevent the movement of the elastic clamping part 12 from being obstructed by paint, the elastic clamping part 12 includes: a fixing block 121, a first elastic element 122, and a clamping cover 123. The fixing block 121 is fixed on the clamping ring 13. The end of the fixing block 121 away from the clamping ring 13 is fitted with a clamping cover 123 that can move radially upwards from the clamping ring 13. The first elastic element 122 is connected between the clamping cover 123 and the fixing block 121. The first elastic element 122 is covered by the clamping cover 123 and the fixing block 121, thereby preventing the first elastic element 122 from being exposed and affecting its movement, and preventing paint from affecting the movement of the clamping cover 123 in the movement gap between the fixing block 121 and the clamping cover 123. The elastic force of the first elastic element 122 is used to keep the clamping cover 123 pressed against the motor stator.

[0030] To enable the elastic clamping part 12 to automatically release the motor stator, a pull-out actuator 9 is installed on the mounting bracket 3. The pull-out actuator 9 is used to pull the elastic clamping part 12 away from the two fixed clamping parts 11. A second clamping surface is provided at the end of the clamping cover 123 away from the clamping ring 13. The outer wall of the end of the clamping cover 123 near the clamping ring 13 protrudes to form a protruding ring 124. The protruding ring 124 is pulled by the pull-out actuator 9. The protruding ring 124 can not only be pulled by the pull-out actuator 9, but when the paint drips vertically, the elastic clamping part 12 will only catch the paint when it is located below the motor stator. The protruding ring 124 can also catch the dripping paint, preventing the paint from entering the moving gap between the clamping cover 123 and the fixed block 121, so that the possibility of the paint entering the moving gap between the clamping cover 123 and the fixed block 121 is almost zero.

[0031] In this application, to prevent the motor stator from falling when the elastic clamping part 12 automatically releases the motor stator, and also to prevent the motor stator from falling when it is initially placed on the fixed clamping part 11, the following design is made: In step S1, the clamping device 1 needs to maintain the following state: the line connecting the positions of the two fixed clamping parts 11 is parallel to the horizontal plane. When the line connecting the positions of the two fixed clamping parts 11 is parallel to the horizontal plane, the fixed clamping parts 11 can stably support the motor stator when the robot or operator places the motor stator on the two fixed clamping parts 11, preventing the motor stator from falling and causing damage to the motor stator product, and also preventing the motor stator from dripping and injuring the operator, thus improving production safety.

[0032] The rotation axis around the top of the clamping base 2 relative to the mounting bracket 3 is parallel to the horizontal plane. This ensures that the angle between the motor stator axis and the horizontal plane is acute after the clamping device 1 is flipped.

[0033] To facilitate the subsequent installation of the next motor stator and to facilitate the support of the motor stator released by the elastic clamping part 12, step S4 is executed after step S3. Step S4 includes the following steps: the axis position drive device 4 drives the clamping base 2 to return to the loading station.

[0034] In order to support the motor stator that is not clamped by the elastic clamping part 12, step S4 also performs the following steps: the self-rotation drive device 6 drives the clamping device 1 to rotate until the clamping device 1 rotates relative to the clamping base 2 to the loading station. At the loading station, the line connecting the positions of the two fixed clamping parts 11 in the clamping device 1 is parallel to the horizontal plane.

[0035] To improve the overall neatness of the production layout, at least two lightweight, high-efficiency, and energy-saving new energy vehicle motor paint spraying systems are installed, and all lightweight, high-efficiency, and energy-saving new energy vehicle motor paint spraying systems are arranged in rows.

[0036] In this application, by setting "the top of the clamping base 2 can be rotatably mounted on the mounting frame 3, and an axis position drive device 4 is mounted on the mounting frame 3. The output end of the axis position drive device 4 is connected to the bottom of the clamping base 2, and the rotation axis of the top of the clamping base 2 relative to the mounting frame 3 is parallel to the horizontal plane", the following functions are achieved: After the center line of the motor stator is flipped, the inner holes at both ends of the motor stator can be flipped to the upward position. The paint dripping execution device 5 is provided with two output ends, which are respectively aligned with the two sides of the clamping device 1, so that paint can be dripped onto the inner holes at both ends of the motor stator. After clamping the motor stator at one time, paint can be dripped onto the inner holes at both ends of the motor stator, ensuring the paint dripping efficiency, avoiding the need for robot transfer, and achieving energy saving effect.

[0037] The mounting bracket, clamping base, and clamping ring are all frame-type structures, thus achieving a lightweight effect.

[0038] To position the end face of the motor stator, a driving mechanism 81 and an end positioning mechanism 82 are installed at the elastic clamping part 12. The movable part in the elastic clamping part 12 acts on the first end of the driving mechanism 81, and the second end of the driving mechanism 81 acts on the first end of the end positioning mechanism 82. The end positioning mechanism 82 can move radially relative to the motor stator. A second elastic member 83 is connected between the end positioning mechanism 82 and the clamping ring 13. The driving mechanism 81 is used to allow the second end of the end positioning mechanism 82 to extend into a position that is in close contact with the end face of the motor stator when the movable part in the elastic clamping part 12 (i.e., the clamping cover 123) is pulled away from the motor stator by the pull-out actuator 9.

[0039] The driving mechanism 81 is a rod-type structure, and its middle part is rotatably connected to the clamping ring 13. The end positioning mechanism 82 is a block-shaped structure. Under the elastic force of the second elastic member 83, the end positioning mechanism 82 is kept away from the elastic clamping part 12. When the movable part in the elastic clamping part 12 is pulled away from the motor stator by the pull-away actuator 9, the driving mechanism 81 causes the end positioning mechanism 82 to extend across the elastic clamping part 12. This achieves the following: when the motor stator is placed, the pull-away actuator pulls the elastic clamping part 12 to keep it close to the clamping ring 13. At the same time, the clamping cover 123 pushes the driving mechanism 81 to rotate, and the second end of the driving mechanism 81 pushes the end positioning mechanism 82 out. The end positioning mechanism 82 can be tightly attached to the end face of the motor stator located on the fixed clamping part 11. When the pull-out actuator releases the elastic clamping part 12, the elastic clamping part 12 remains in cooperation with the fixed clamping part 11 to clamp the motor stator under the elastic force of the first elastic member 122. At this time, the drive mechanism 81 loses its thrust on the end positioning mechanism 82, and the end positioning mechanism 82 retracts to the direction close to the clamping ring 13 under the elastic force of the second elastic member 83.

[0040] In this application, firstly, it breaks away from the existing technology where the axis of rotation of the fixed frame relative to the external mounting frame 3 is located in the vertical direction. Instead, it designs the rotation axis of the top of the clamping base frame 2 relative to the mounting frame 3 to be parallel to the horizontal plane. This allows the motor stator held by the clamping device 1 to change from the loading station to the paint dripping station. In the loading station, the axis of the motor stator is parallel to the horizontal plane. In the paint dripping station, the angle between the axis of the motor stator and the horizontal plane is acute. This causes the inner wall of the motor stator's inner hole to tend upwards, ensuring that the vertically dripping paint can drip into the inner wall of the motor stator's inner hole, thus guaranteeing the quality of the product after paint dripping. Then, in order to ensure that when the elastic clamping part 12 is not clamping the motor stator during loading or unloading, the two fixed clamping parts 11 are in the same horizontal position, and the two fixed clamping parts 11 can stably support the bottom of the motor stator. This allows time to wait for the elastic clamping part 12 to clamp the motor stator after it is placed on the fixed clamping part 11, and also ensures time to wait for the motor stator to be transferred after it is released by the elastic clamping part 12.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
