[0017] Beneficial effects

[0018] Compared with the prior art, the present invention provides a stator paint dripping machine and a paint dripping method for a multi-angle inclined hub motor stator, having the following beneficial effects:

[0019] 1. A stator paint dripping machine and a paint dripping method for a multi-angle inclined hub motor stator. Through the arrangement of the driving member, when the support plate drives the stator body to rotate upward, the gear contacts the driving member, resulting in the folding of the movable joint rod and the upward inclination of the movable rod, and further making the stator body in an inclined state, so that the paint in the paint dripper can drip onto the coil inside the stator body, solving the problem that the copper coil of the hub motor stator is very few outside the iron core and it is difficult to drip onto the coil after the traditional paint dripping method, resulting in the coil on the outer periphery of the stator not being completely wrapped by the dripping paint;

[0020] 2. A stator paint dripping machine and a paint dripping method for a multi-angle inclined hub motor stator. Through the meshing connection between the tooth blocks on the outer periphery of the frustum in the driving member and the gear, after the stator body is positioned directly below the paint dripper, the driving member operates to drive the gear to rotate, thereby driving the movable rod, the bearing member on one side of the movable rod, and the stator body on the bearing member to rotate, so that the paint in the paint dripper can be evenly dripped onto the coil inside the stator body, ensuring uniform wrapping of the paint on the surface of the coil inside the stator body;

[0021] 3. A stator paint dripping machine and a paint dripping method for a multi-angle inclined hub motor stator. Through the arrangement of the pushing member, after the stator body finishes dripping paint, the support plate rotates downward, so that the stator body is located above the transport bed. The pushing member operates and drives the round roller to move downward. The round roller contacts the connecting plate and applies a downward pressure to the connecting plate. Through the movable hinge between the connecting plate and the movable rod, the connecting plate rotates downward, so that the bearing member and the stator body mounted on the bearing member change from a horizontal state to a vertical state. At the same time, the round roller continues to move downward, causing the push plate to move towards the sleeve plate direction, making the sleeve plate move downward and separate from the inner plate, so that the stator body and the bearing rod carrying the stator body fall onto the transport bed. At the same time, through the socket connection between the sleeve plate and the inner plate and the snap connection between the block and the slot, a new stator body and bearing rod are assembled onto the connecting plate, facilitating the quick disassembly and assembly of the stator body in this device.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a stator paint dripping machine and a paint dripping method for a hub motor stator with multi-angle inclination.

[0033] Embodiment 1

[0034] Please refer to Figures 1-6 , a stator paint dripping machine, including a paint dripping device 1, on which a stator body 2 is installed. A transport bed 3 for transporting the stator body 2 is provided at the bottom of the paint dripping device 1. Paint drippers 4 are installed on both sides of the top of the paint dripping device 1. The paint dripping device 1 includes a support plate 11, brackets 12 provided on both sides of the top of the support plate 11, and a driving source 13 for controlling the rotation of the support plate 11;

[0035] A bearing plate 14 is provided on the top of the support plate 11. Movable joint rods 15 are provided on both sides of the top of the bearing plate 14. One end of the movable joint rod 15 is hinged with a movable rod 16. A gear 17 is fixedly installed on the movable rod 16. A bearing member 18 is provided at one end of the movable rod 16. The stator body 2 is installed on the bearing member 18;

[0036] A driving member 5 is provided on the bracket 12. The driving member 5 is power-transmitted with the gear 17. When the support plate 11 drives the movable rod 16 to rotate upward and the gear 17 contacts the driving member 5, the movable joint rod 15 is bent, and the movable rod 16 and the stator body 2 at one end of the movable rod 16 are in an inclined state. The operation of the driving member 5 drives the movable rod 16 and the stator body 2 at one end of the movable rod 16 to be in a rotating state.

[0037] Specifically, a plurality of stator bodies 2 are installed on the bearing member 18. Then, the driving source 13 drives the support plate 11 to rotate. During the process that the support plate 11 drives the stator body 2 to rotate to the top of the bracket 12, when the gear 17 on the movable rod 16 contacts the driving member 5, due to the setting of the movable joint rod 15, the movable rod 16 is inclined, and the gear 17 is closely attached to the surface of the driving member 5. At this time, the movable rod 16, the bearing member 18 at one end of the movable rod 16, and the stator body 2 on the bearing member 18 are all in an inclined state. Then, the driving member 5 is started. The driving member 5 operates to drive the gear 17 to rotate, thereby driving the movable rod 16, the bearing member 18 at one end of the movable rod 16, and the stator body 2 on the bearing member 18 to rotate while being in an inclined state. Then, through the paint dripper 4, paint is dripped onto the stator body;

[0038] With the setting of the driving member 5, when the supporting plate 11 drives the stator body 2 to rotate upward, the gear 17 contacts the driving member 5, which causes the movable joint rod 15 to fold, and makes the movable rod 16 in an upward inclined state. Furthermore, the stator body 2 is in an inclined state, so that the paint dripping in the paint dripper 4 can drip onto the coil in the stator body 2, solving the problem that the copper coil of the in-wheel motor stator is very few outside the iron core, and it is difficult to drip onto the coil after the traditional paint dripping method, resulting in the coil on the outer periphery of the stator not being completely wrapped by the dripping paint.

[0039] Embodiment 2

[0040] The difference from the above Embodiment 1 is that, referring to Figures 4-6 , for the above driving member 5, the paint dripping device 1 further includes a frame 19. A plurality of paint drippers 4 are fixedly installed on both sides of the top of the frame 19. Both ends of the supporting plate 11 are rotatably arranged on both sides of the inner cavity of the frame 19 through bearings. The driving source 13 includes a first motor 131. The first motor 131 is fixedly installed outside the frame 19 and its output end is fixedly connected to one end of the supporting plate 11. Two brackets 12 are respectively fixedly installed on both side walls of the inner cavity of the frame 19 and are located above the supporting plate 11. The transport bed 3 is arranged at the bottom of the inner cavity of the frame 19;

[0041] The movable joint rod 15 includes a fixed plate 151 and a movable plate 152. One end of the movable plate 152 is hinged with a main hinge plate 153. One end of the fixed plate 151 is hinged with a secondary hinge plate 154. A first torsion spring 155 is installed at the hinge between the main hinge plate 153 and the movable plate 152. A second torsion spring 156 is installed at the hinge between the secondary hinge plate 154 and the fixed plate 151. One end of the main hinge plate 153 is fixedly connected with a main right-angle plate 157. A guide rod is fixedly connected between the horizontal part of the main right-angle plate 157 and the main hinge plate 153. One end of the secondary hinge plate 154 is fixedly connected with a secondary right-angle plate 158. The horizontal part of the secondary right-angle plate 158 is slidably arranged on the guide rod. A first spring 159 is installed between the horizontal part of the secondary right-angle plate 158 and the horizontal part of the main right-angle plate 157. The first spring 159 is sleeved on the guide rod;

[0042] Vertical plates 110 are fixedly connected to both sides of the supporting plate 11. A bearing plate 14 is fixedly installed on the vertical plates 110. Two fixed seats 111 are installed in the middle part of the bearing plate 14. The fixed plate 151 is fixedly installed on the two fixed seats 111. Hinge seats 112 are fixedly installed on both sides of the top of the bearing plate 14. The movable plate 152 is arranged on the hinge seats 112 and is movably hinged with the hinge seats 112. One end of the movable rod 16 is rotatably arranged at one end of the movable plate 152 through a bearing;

[0043] The driving member 5 includes a circular plate 51. The side surface of the circular plate 51 is set as an inclined surface. One side at the top of the bracket 12 is fixedly installed with a base 52. The top of the base 52 is fixedly installed with a support 53. The circular plate 51 is in a vertical state and is rotationally connected to the support 53 through a bearing at the axis. A support plate 54 is fixedly installed on the base 52. Both ends on one side of the support plate 54 are rotationally connected with pulleys 55 through bearings. A transmission belt 56 is sleeved on the pulleys 55. A second motor 57 is fixedly installed on the base 52. The output end of the second motor 57 is fixedly connected to one of the pulleys 55. A plurality of tooth blocks 58 are fixedly installed on the inclined surface outside the circular plate 51. The tooth blocks 58 are meshed and connected with the gear 17.

[0044] Specifically, the first motor 131 drives the support plate 11 to rotate, so that the stator body 2 on the support plate 11 rotates from bottom to top. When the movable joint rod 15, the movable rod 16 and the connecting plate 181 are in a collinear state, the height of the frustum in the vertical direction is higher than the height of the whole formed by the movable joint rod 15, the movable rod 16 and the connecting plate 181 in the vertical state. Thus, after the gear 17 on the movable rod 16 contacts the frustum, rotation occurs between the movable plate 152 and the main hinge plate 153, and rotation occurs between the fixed plate 151 and the secondary hinge plate 154. As a result, the first torsion spring 155 and the second torsion spring 156 are in a compressed state. At the same time, the distance between the main right-angle plate 157 and the secondary right-angle plate 158 increases, so that the first spring 159 is in a compressed state. When the whole formed by the movable joint rod 15, the movable rod 16 and the connecting plate 181 is in the vertical state, the movable rod 16 is in an inclined state, and through the elastic forces provided by the first torsion spring 155, the second torsion spring 156 and the first spring 159, the gear 17 is attached to the frustum. At the same time, the second motor 57 operates. Through the setting of the transmission belt 56, the two pulleys 55 are driven to rotate, thereby driving the frustum to rotate. Through the meshing connection between the tooth blocks 58 on the frustum and the gear 17, the gear 17 is driven to rotate, thereby driving the movable rod 16 to rotate, and further driving the carrier 18 connected to the movable rod 16 and the stator body 2 installed on the carrier 18 to rotate, so that the paint in the paint dripping device 4 drips evenly onto the coil in the stator body 2, ensuring that the paint on the surface of the coil in the stator body 2 is evenly wrapped.

[0047] A rectangular groove 188 is formed in the connecting plate 181. A guide shaft is fixedly connected in the rectangular groove 188. A rectangular block 189 is slidably arranged in the rectangular groove 188. The rectangular block 189 is sleeved outside the guide shaft and a second spring 1810 is fixedly connected to the side close to the paint shielding plate 184. The second spring 1810 is sleeved on the guide shaft. One side of the rectangular block 189 is fixedly connected with a baffle 1811. A push plate 1812 is fixedly connected to the side of the baffle 1811 close to the paint shielding plate 184. The push plate 1812 passes through the paint shielding plate 184 and one end thereof contacts with one side of the sleeve plate 186. The sleeve plate 186 includes a main board 1861 and side plates 1862 arranged at both ends on one side of the main board 1861. The inner plate 185 is arranged between the two side plates 1862. A groove 1863 is formed in one side of the side plate 1862. A clamping plate 1864 is slidably arranged in the groove 1863. A third spring 1865 is fixedly connected to one side of the clamping plate 1864. The third spring 1865 is arranged in the groove 1863. A clamping block 1866 is fixedly connected to the other side of the clamping plate 1864. Card slots 1867 are formed on both sides of the inner plate 185. The clamping block 1866 is in conformity with the card slots 1867. Arcs are formed at the side edges of the clamping block 1866 close to the card slots 1867;

[0048] Pushing members 6 are arranged on both sides of the bottom of the support plate 11. The pushing member 6 includes a round roller 61. A suspension plate 62 is fixedly connected to the bottom of the support plate 11. A sliding groove 63 is formed in one side of the suspension plate 62.

Sliding seats 66 are fixedly connected to both sides of the moving plate 64. The sliding seats 66 and the reciprocating lead screws 65 are assembled by threads. A rotating rod 67 is rotatably connected in the suspension plate 62 through a bearing. Bevel gear sets are fixedly connected to both sides of the rotating rod 67 and one end of each of the reciprocating lead screws 65. A third motor 68 is fixedly connected to one side of the suspension plate 62. The output end of the third motor 68 is fixedly connected to one end of the rotating rod 67. A round shaft is fixedly connected to one side of the moving plate 64. The round roller 61 is sleeved outside the round shaft;

[0049] A cooling fan 7 is installed at the top end inside the frame 19. A fourth motor 8 is fixedly installed at the top end outside the frame 19. The output end of the fourth motor 8 is fixedly connected to the input end of the cooling fan 7. A paint receiving tray 9 is fixedly installed on the support 12;

[0050] Specifically, after the stator body 2 is finished with drip painting, the support plate 11 rotates again, causing the whole formed by the movable joint rod 15, the movable rod 16, and the connecting plate 181 to rotate from top to bottom. When the gear 17 disengages from the frustum, the elastic forces provided by the first torsion spring 155, the second torsion spring 156, and the first spring 159 cause the folded movable joint rod 15 and the inclined movable rod 16 to return to their original positions, so that the movable joint rod 15, the movable rod 16, and the connecting plate 181 are collinear again. When the movable rod 16 is at the bottom of the support plate 11, the third motor 68 drives the rotating rod 67 to rotate. Through the arrangement of the bevel gear set, the two reciprocating lead screws 65 are driven to rotate. Through the threaded connection between the reciprocating lead screw 65 and the sliding seat 66, the moving plate 64 is driven to move downward, so that the round roller 61 contacts the connecting plate 181. Through the movable hinge between the connecting plate 181 and the secondary hinge plate 182, the connecting plate 181 rotates from the horizontal state, causing the connecting plate 181 to rotate from the horizontal state to the vertical state. The moving plate 64 continues to move downward, driving the baffle 1811 and the push plate 1812 on one side of the baffle 1811 to move downward. Through the arrangement that the side edge of the block 1866 is circular, the block 1866 disengages from the card slot 1867, so that the sleeve plate 186 disengages from the inner plate 185, and further enables the bearing rod 187 and the stator body 2 on the bearing rod 187 to move onto the transport bed 3. At the same time, the new bearing rod 187 and the stator body 2 move to one side of the inner plate 185. Through the arrangement that the side edge of one side of the block 1866 is circular, the block 1866 coincides with the card slot 1867.
