Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor production, and particularly relates to a motor production equipment. BACKGROUND

[0002] In the production process of small motors (such as a scooter driving motor, a motor for electric tools, etc.), the insulating varnishing treatment of the stator winding (after the wire is wound into a coil according to a specific number of turns and pitch, the coil is embedded into the slot of the stator core to form a combination) is a core link to ensure the reliability of the motor. At present, the commonly used varnishing operation mode in the industry is to place the stator winding on a rack, and then immerse the entire rack into the paint for a certain period of time. On the one hand, since the rack and the stator winding are in a static state during the varnishing process, the paint only slowly infiltrates into the stator winding by its own gravity and capillary action, which is difficult to quickly and fully infiltrate into the stator winding in a short time, resulting in a long time required for varnishing, greatly reducing the varnishing efficiency of the stator winding, and further affecting the production rhythm and capacity of the entire motor production. On the other hand, the part of the stator winding in contact with the rack cannot be directly contacted by the paint due to the shielding of the rack, which makes it difficult to effectively varnish the contact part, and further affects the overall varnishing effect of the stator winding.

[0003] Therefore, the present application provides a motor production equipment to solve the above problems. SUMMARY

[0024] The stator winding to be painted is placed in the placement area 4, one placement area 4 corresponds to one stator winding, the stator winding is continuously poured with paint by the pouring assembly 2, during which the stator winding is driven to reciprocatingly and suspendedly lift by the lifting assembly 5, the stator winding produces vibration when suspendedly descending and contacting the bottom side of the painting cavity 101, which can promote the infiltration of the paint, and the bottom side of the stator winding is exposed (not in contact with the bottom side of the painting cavity 101) when suspendedly lifting, so as to be able to contact and adhere to the paint, avoiding the constant contact between the bottom side of the stator winding and the bottom side of the painting cavity 101, so that the stator winding is fully painted, effectively improving the painting efficiency and effect of the stator winding, and further improving the motor production efficiency and the quality of the motor product obtained in subsequent production; the stator winding is limited by the limiting assembly 3, so as to always be suspendedly lifted within the range of the placement area 7, avoiding the damage caused by the collision between the stator windings.

[0025] Please refer to Figures 1 to 4 In an embodiment of the present application, the box 1 further comprises a paint containing cavity 102 for containing paint, one side of the paint containing cavity 102 is provided with a material opening for adding paint and a transparent window arranged upward and downward, the transparent window is provided with a capacity scale line for reading the amount of paint in the paint containing cavity 102 (the material opening, the transparent window and the capacity scale line are not shown in the drawing), the paint containing cavity 102 is located below the painting cavity 101, and the upper side of the painting cavity 101 is open, the pouring assembly 2 comprises a cover piece 202 which is opened and closed on the box 1 and is matched with the painting cavity 101, the inside of the cover piece 202 is hollow, and the cover piece 202 is uniformly provided with pouring holes 203 towards the inside, the placement area 4 is provided with a discharging hole 204 which is communicated with the paint containing cavity 102, and the pouring assembly 2 further comprises a circulating pump 201 for pumping paint into the cover piece 202 (the output end of the circulating pump 201 is communicated with the cover piece 202 through a paint guide hose, and the paint enters the cover piece 202 through the paint guide hose).

[0026] In the embodiment, after the stator winding is placed, the cover piece 202 is closed on the upper side of the paint cavity 101, the paint in the paint containing cavity 102 is pumped into the cover piece 202 by the circulating pump 201, and then poured on the stator winding through the pouring holes 203, the paint not adhered to the stator winding returns to the paint containing cavity 102 through the discharging hole 204, and the process is repeated and continued for a certain period of time, so as to paint the stator winding.

[0027] Further, in the embodiment, the cover 202 is hinged to one side of the box 1, and the pouring assembly 2 further comprises a driving component (not shown in the figure) for driving the cover 202 to open and close. The driving component can be a gear, a rack, and an additional electric push rod structure.

[0029] In the embodiment, when the stator winding is placed before painting and the stator winding is taken after painting, the telescopic member 303 is in an extended state (illustrated at an angle shown in Figure 1 ), so that the part of the rod segment of the blocking rod 302 protruding from the bottom side of the painting cavity 101 is short, and does not affect the placement and taking of the stator winding. During painting, the telescopic member 303 is in a contracted state, so that the part of the rod segment of the blocking rod 302 protruding from the bottom side of the painting cavity 101 reaches a certain length, and plays a role of separating the placement areas 4, so as to avoid the stator windings from being damaged by knocking each other when being lifted.

[0030] Further, in the embodiment, the carrier 301 and the blocking rods 302 are hollow, the upper end of the blocking rod 302 is closed, the lower end is open and communicates with the interior of the carrier 301, when the carrier 301 is in the upper position, the blocking rods 302 are located on the rod segments in the upper lacquering cavity 101, the through holes 304 are uniformly arranged on the rod segments, the circulating pump 201 also pumps the paint into the carrier 301 (the output end of the circulating pump 201 also communicates with the carrier 301 through the paint guide hose, and the paint enters the carrier 301 through the paint guide hose), the paint pumped into the carrier 301 is distributed into each blocking rod 302, and then is sprayed out through the through holes 304, so that the paint is sprayed from the direction of the stator winding to the stator winding, and the lacquering efficiency of the stator winding is further improved.

[0031] Further, in the embodiment, the blocking rod 302 is sleeved with a protective rubber sleeve (not shown in the figure), and the placing area 4 is provided with a protective rubber pad (not shown in the figure), so that the stator winding is prevented from being touched by the blocking rod 302 when being lifted and from being damaged by touching the bottom side of the upper lacquering cavity 101 when falling.

[0032] Please refer to Figure 1 and Figure 3 In an embodiment of the present application, the lifting assembly 5 comprises the inner recessed areas 501 corresponding to the placing areas 4 on the cover 202, and the electromagnets 502 for magnetically attracting the stator windings to make them be lifted in the air are arranged in the inner recessed areas 501.

[0033] In the embodiment, the electromagnets 502 are intermittently powered on during the paint pouring, the corresponding stator windings (acting on the stator core) are magnetically attracted and lifted in the air by the electromagnets 502 when the electromagnets 502 are powered on to generate magnetism, the bottom side of the stator winding is exposed so as to be able to contact and adhere to the paint, the stator winding is lowered by its own gravity to touch the bottom side of the upper lacquering cavity 101 to generate vibration when the electromagnets 502 are powered off to generate demagnetism, and the paint infiltration is promoted; it should be noted that the electromagnets 502 are powered on for a short time, and the stator winding will not be lifted to contact the electromagnets 502 during this period.
