[0023] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0024] Embodiment 1: The present application provides a motor stator vacuum dipping device, comprising a dipping box 1; a vacuum pump 2 is installed on the side of the dipping box 1, a dipping chamber 101 is provided inside the dipping box 1, and two sets of processing mechanisms 6 are installed on the top of the dipping box 1;

[0025] The processing mechanism 6 includes a heating box 601, a heating plate 602, a fan 603 and an air induction plate 604. Two sets of heating boxes 601 are installed on the top of the paint dipping box 1. The inner top of the heating box 601 is installed with a heating plate 602. The inner wall of the heating plate 602 is provided with an air induction plate 604. The top of the heating box 601 is installed with a fan 603;

[0026] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the processing mechanism 6 is arranged on the top of the paint dipping box 1, and is used for pre-treating the motor stator before paint dipping. The heating box 601 is composed of a box body and a box door. The air induced plate 604 is n-shaped and is connected to the inside of the heating plate 602. A plurality of through holes are provided on a side close to the air induced plate 604. The heating plate 602 works to convert electrical energy into thermal energy, and then the gas is blown into the inside of the heating box 601 through the work of the fan 603. The heated gas will be blown toward the motor stator inside the heating box 601 along the air induced plate 604, so that the temperature of the motor stator can be increased, and then the motor stator is transported to the inside of the paint dipping chamber 101. The vacuum pump 2 works to make the inside of the paint dipping chamber 101 vacuum, and then the paint body is transported to the inside of the paint dipping chamber 101, and the motor stator is treated with paint dipping. When the temperature of the motor stator is increased, the paint body will be better and faster attached to the outer surface of the motor stator. At the same time, when the motor stator after paint dipping moves to the inside of the heating box 601, the drying of the gas on the outer surface of the motor stator can be accelerated.

[0027] Furthermore, a rotating roller 7 is rotatably installed on the inner top of the heating box 601, a connecting rope 701 is wound around the outer side of the rotating roller 7, a placing frame 702 is installed at the bottom of the connecting rope 701, and a placing roller 703 is placed inside the placing frame 702;

[0028] Specifically, Figure 3 As shown, in order to realize the conveying and varnishing treatment of the motor stator, the motor stator is passed through the outside of the placement roller 703, and the placement roller 703 is then clamped inside the placement rack 702. At this time, the connecting rope 701 is driven to be retracted and released by the rotating roller 7, so that the connecting rope 701 drives the placement rack 702 at the bottom to move to the inside of the varnishing box 1, so that the motor stator can be dipped in paint inside the varnishing box 1.

[0029] Further, a limit plate 704 is rotatably mounted on the top of the placement rack 702;

[0030] Specifically, Figure 3 As shown, in order to fix the placement roller 703 with the motor stator, the limit plate 704 is rotatably installed on the top of the placement rack 702. When the worker places the two ends of the placement roller 703 with the motor stator in the fixed groove inside the placement rack 702, and then rotates the limit plate 704, when the limit plate 704 is located at the top of the placement rack 702, the placement roller 703 can be limited and fixed inside the placement rack 702, avoiding the placement roller 703 from falling off during the movement, and at the same time facilitating the worker to quickly remove the placement roller 703.

[0031] Furthermore, a through opening 104 is provided inside the paint dipping box 1 near the heating box 601, a driving device 8 is installed on the inner top of the paint dipping box 1 near the through opening 104, and a baffle 801 is movably installed outside the driving device 8;

[0032] Specifically, Figure 1 As shown, in order to achieve closed heating of the motor stator inside the heating box 601, the driving device 8 is an existing electromagnetic slide rail structure, and the baffle 801 is driven to move by the driving device 8. When the baffle 801 is located at the bottom of the through opening 104, the heating box 601 can be closed, thereby accelerating the drying speed of the motor stator and preventing the temperature inside the heating box 601 from being transferred to the inside of the paint dipping box 1, causing the paint body inside the paint dipping box 1 to solidify.

[0033] Furthermore, a discharge pipe 3 is installed at the bottom of the varnish dipping chamber 101, and a separation chamber 102 is provided near the bottom of the varnish dipping chamber 101 in the varnish dipping box 1, and a filter plate 4 is installed inside the separation chamber 102;

[0034] Specifically, Figure 1 As shown, in order to separate the paint body, the paint body in the paint immersion chamber 101 is transported to the separation chamber 102 by opening the outer valve of the discharge pipe 3. At this time, the paint body and the impurities mixed therein can be separated by the filter plate 4, and then the separated paint body can be transported and used again.

[0035] Furthermore, the lacquer dipping box 1 is provided with a cavity 103 on the side close to the lacquer dipping chamber 101 and the separation chamber 102, and a delivery pump 5 is installed inside the cavity 103;

[0036] Specifically, Figure 1 As shown, in order to realize the recycling of the paint body, the delivery pump 5 is arranged inside the cavity 103, the input end of the delivery pump 5 is connected to the separation chamber 102, and the output end is connected to the paint immersion chamber 101. Through the operation of the delivery pump 5, the paint body filtered inside the separation chamber 102 can be transported to the paint immersion chamber 101 again for use, thereby realizing the recycling of the paint body.

[0037] Working principle: The motor stator is passed through the outside of the placement roller 703, and the placement roller 703 is clamped inside the placement frame 702. Then, the gas is blown into the interior of the heating box 601 through the operation of the fan 603. The heated gas will be blown toward the motor stator inside the heating box 601 along the air duct plate 604. At this time, the connecting rope 701 is driven to be retracted and released through the rotating roller 7, so that the connecting rope 701 drives the motor stator to move to the interior of the paint dipping box 1. The vacuum pump 2 is operated to make the interior of the paint dipping chamber 101 evacuated, and then the paint body is transported to the interior of the paint dipping chamber 101 for paint dipping treatment of the motor stator.

[0038] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
