[0002] After the motor stator is wound, it is dipped in varnish and dried, and all air gaps are filled with insulating varnish. This can not only improve the insulation strength and moisture resistance of the winding, but also improve the heat resistance and heat dissipation of the winding. It can also improve the mechanical properties, chemical stability, thermal conductivity and heat dissipation effect of the winding insulation and delay aging. The quality of the varnish directly affects the temperature rise and service life of the motor.

[0003] The traditional way of dipping paint, as shown in the patent "Suspended basket for dipping paint of motor stators" with announcement number CN206911665U, is to place the motor stators one by one into the suspended basket, and then immerse the suspended basket into the insulating paint. The problem is that the motor stators are heavy, and it is time-consuming and laborious to manually carry them one by one into the suspended basket; secondly, each stator needs to be placed in the position corresponding to the positioning column, but the motor manufacturers produce many types of motors, and the sizes of stators are different. Each type of stator needs to be equipped with a different suspended basket, which has poor versatility and increases production costs. Summary of the invention

[0024] The working principle includes: the base frame 1 is used as the base of the tray, and multiple stators 3 with windings are mounted through the round rods 2; the positioning position is fixed by the positioning block 4 and the dividing frame 5. Due to the dense insertion holes 21 on the round rods 2, the axial spacing of the stators 3 can be adjusted to accommodate stators 3 of different lengths; and due to a row of dense threaded holes 13, the spacing between two adjacent round rods 2 can be adjusted to accommodate stators 3 of different diameters. For example, when mounting a stator 3 with a larger diameter, Figure 1On the basis of the base 1, a round rod 2 is removed, so that a stator 3 with a larger diameter can be accommodated, which improves versatility and can still ensure that the stators 3 are densely arranged on the base frame 1 to ensure space utilization efficiency. At the same time, a round rod 2 is mounted with a string of stators 3. The round rod 2 can be hooked by a lifting device, so that a string of stators 3 can be transferred at a time, which is labor-saving and convenient, and improves efficiency. For example, through manual operation, the round rod 2 is passed through a string of stators 3 placed on the shelf, and then hoisted by a crane. As a lifting component, the round rod 2 can be directly placed on the base frame 1, and the weight is much lighter than a string of stators 3. People carry and transfer the round rod 2 to reduce labor intensity. Among them, the lifting lug 12 is connected to the lifting device to transfer the base frame 1 equipped with the stator 3 for paint dipping operation.

[0025] When in use, firstly, the round rod 2 is passed through a plurality of stators 3, and the dividing frame 5 is installed on both sides of each stator 3, and the latch 53 is inserted. Then, by lifting the two ends of the round rod 2, a string of stators 3 is transferred from the shelf to the upper surface of a pair of beams 11. Repeat the above steps to place multiple strings of stators 3 on the base frame 1. Then, a positioning block 4 is respectively installed on both ends of the round rod 2; the round rod 2 is slid until the positioning hole 41 and the threaded hole 13 are aligned and overlapped, and the positioning block 4 is fixed by inserting a bolt. Then, the lifting equipment is connected through the lifting ear 12, and the base frame 1 equipped with the stator 3 is transferred for paint dipping operation, or into the drying box for drying operation.

[0026] Exemplarily, the positioning block 4 includes a block body 42; a lower edge of one side of the block body 42 extends downward to form an extension portion 43; the positioning hole 41 is provided in the extension portion 43; the block body 42 is provided with a fitting hole 44 for fitting onto the round rod 2. It can be seen that the block body 42 can be fitted onto the two ends of the round rod 2 respectively. After the block body 42 is fitted onto the round rod 2, the round rod 2 can still slide on the crossbeam 11 until the positioning hole 41 and the threaded hole 13 are aligned and overlapped, so as to facilitate the installation of the bolt.

[0027] For ease of operation, the bolt is a butterfly bolt 45. No wrench tool is needed, and it is convenient to screw.

[0028] Exemplarily, the split frame 5 includes a sleeve portion 54 having the through hole 51 at the center; a plurality of circumferentially spaced and evenly distributed support rods 55 are fixedly connected to the outer surface of the sleeve portion 54; and the connecting hole 52 passes through the sleeve portion 54. The split frame 5 prevents two adjacent stators 3 from colliding during the transfer of the base frame 1. Preferably, the split frame 5 is made of hard plastic material to reduce the damage to the stator 3 caused by collision.

[0029] Preferably, the round rod 2 is provided with a pair of shaft shoulders 22, so that when the round rod 2 is mounted on the upper surface of the pair of beams 11, the pair of shaft shoulders 22 are respectively supported on the inner side of the pair of beams 11. The round rod 2 is more firmly fixed to avoid the round rod 2 from moving during the transfer process.

[0030] The advantages of this embodiment are as follows:

[0031] (1) A string of stators 3 can be stored and retrieved at one time, which is labor-saving and convenient, and improves efficiency.

[0032] (2) The axial spacing of the stators 3 and the spacing between each string of stators 3 can be adjusted to accommodate stators 3 of different sizes, thereby improving versatility.

[0033] (3) Except for the base frame 1, all other parts can be disassembled and replaced and maintained easily.

[0034] (4) The device has a simple structure and low manufacturing cost.

[0035] In summary, this embodiment can accommodate stators 3 of different sizes, thereby improving versatility, reducing production costs, facilitating storage and access to the stators 3, and improving efficiency.
