Description

Technical Field

[0001] The invention relates to the technical field of stator processing, and in particular to a stator paint dripping process. Background Art

[0002] At present, stators are usually processed by dripping paint. During the dripping process, temperature is a key factor affecting the fluidity of the paint and the coating effect. However, maintaining a constant temperature can be a challenge because temperature fluctuations affect the fluidity and curing effect of the paint. If the temperature is not properly controlled, it may cause problems such as uneven paint film, bubble generation or incomplete curing. Summary of the invention

[0003] The object of the present invention is to provide a stator paint dripping process, which can well control the temperature during stator curing and paint dripping.

[0004] A stator paint dripping process provided by the present invention comprises the following steps:

[0005] S1: Provide multiple stators;

[0006] S2: preheating a plurality of stators in a preheating furnace;

[0007] S3: coating the surfaces of the preheated stators with powder;

[0008] S4; curing the coated stators in a curing oven;

[0009] S5: dripping paint on a plurality of cured stators;

[0010] The curing furnace is provided with a feed inlet and a discharge port, and the feed inlet and the discharge port of the curing furnace are respectively equipped with pneumatic lifting and heat-insulating doors.

[0011] In actual operation, before curing the stator, the curing furnace must be preheated so that the temperature of the stator remains more stable during subsequent curing.

[0012] Furthermore, in step S2, the preheating time is greater than 60 minutes, and the hot air of the preheating furnace adopts internal circulation, and the temperature range of the preheating furnace is room temperature-200°C.

[0013] Furthermore, the powder is epoxy powder.

[0014] Furthermore, in step S4, the curing heating time is greater than 30 minutes.

[0015] Furthermore, in step S4, a plurality of stators are placed on a tray and the tray is controlled by PLC to enter and exit the curing furnace.

[0016] Furthermore, in step S5, epoxy resin is used for dripping paint. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 The present invention is a flowchart of a stator paint dripping process according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0019] The present invention provides a stator paint dripping process, comprising the steps of:

[0020] S1: Provide multiple stators;

[0021] S2: preheating a plurality of stators in a preheating furnace;

[0022] S3: coating the surfaces of the preheated stators with powder;

[0023] S4; curing the coated stators in a curing oven;

[0024] S5: dripping paint on a plurality of cured stators;

[0025] The curing furnace is provided with a feeding port and a discharging port, and the feeding port and the discharging port of the curing furnace are respectively equipped with pneumatic lifting and heat-insulating doors.

[0026] In actual operation, before curing the stator, the curing furnace must be preheated so that the temperature of the stator remains more stable during subsequent curing.

[0027] In step S2, the preheating time is greater than 60 minutes, and the hot air of the preheating furnace adopts internal circulation, and the temperature range of the preheating furnace is room temperature-200°C.

[0028] Specifically, when the stator is preheated in the preheating furnace, the temperature control in the preheating furnace is divided into three stages:

[0029] Entering the section, the stator is preheated;

[0030] Aging stage: ensure that the product surface temperature is maintained at 165-180℃;

[0031] In the exit section, the product surface temperature is maintained at 165-180℃.

[0032] The powder is epoxy powder.

[0033] In step S4, the curing heating time is greater than 30 minutes.

[0034] In step S4, a plurality of stators are placed on a tray and the tray is controlled by PLC to enter and exit the curing furnace.

[0035] In step S5, epoxy resin is used for dripping paint.

[0036] It is worth mentioning that an automated production line conveying mode is adopted between each of the above steps. The production line conveying adopts a multiple chain form. The conveying part includes: single-layer wire feeding, lifting mechanism, jacking and transverse movement, pallet positioning mechanism, sensor, etc.

[0037] The conveying control device is the main component of the pallet conveying system. It is used to control the stopping, passing and separation of pallets in the pallet conveying system to achieve automatic and flexible control of the pallet conveying process.

[0038] It is worth mentioning that in order to ensure smooth lifting, the lifting mechanism is equipped with a pneumatically controlled one-way valve as standard.

[0039] At the same time, the stator loading and unloading stations are automatic stations. The stator grabbing adopts a truss manipulator arranged across the line. The gripper adopts a large-stroke pneumatic clamp to be compatible with different types of stator outer diameters. The product contact parts are contoured to prevent bumps and scratches on the copper wire and iron core, and the iron core will not warp.

[0040] In the above steps, the stator is placed on a tray and is grasped and moved by a robot.

[0041] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
