Description

Technical Field

[0001] The invention relates to an automatic material pushing and heat preservation furnace, belonging to the technical field of heat preservation furnaces for stator production conveyor lines. Background Art

[0002] The transmission power of the existing line insulation furnace is generally achieved by driving the chain with power, and the chain moves along the guide rail through the rollers set on the chain. This kind of chain transmission, due to the heavy weight to be transmitted, the sprocket driving the chain transmission is also relatively large, and the chain needs to run along a circular track in order to obtain the support of the track and run smoothly. The existing chain transmission conveying device often cannot meet the requirements by only installing the workpiece on the chain to realize the function of conveying the workpiece.

[0003] With the vigorous development of the automobile industry in recent years, various line insulation furnaces for conveying workpieces have required a major upgrade. According to research, the existing chain conveying devices can only drive the chain to move the workpieces in parallel. It is not possible to stably convey and position larger and heavier workpieces, and the insulation and curing of the workpieces are not heated evenly. Therefore, it is particularly important to design and manufacture an automatic loading and unloading line insulation furnace that is convenient for feeding and unloading materials in the conveying line and has a separate control setting, and can realize automatic loading and unloading. Summary of the invention

[0004] The object of the present invention is to address the deficiencies in the prior art and to provide an automatic pushing material insulation furnace, in which the stator and the tray clamp are automatically transported to the conveying line body through a feeding table at one end, the stopper is positioned and blocked, and the tray clamp and the stator are pushed into the line body insulation furnace body in sequence by the pushing mechanism. After the stator and the tray clamp are positioned and arranged by the limiting mechanism in the line body insulation furnace body, the discharge door and the feed door are closed, and an array of insulation and air supply devices are evenly arranged on the top of the line body insulation furnace body, which can evenly insulate the stator in the furnace body, which is helpful to increase the temperature in the furnace and keep it warm. An exhaust gas collector is also provided on the top of the insulation furnace body, so as to collect and discharge the exhaust gas in the insulation furnace body, thereby ensuring stable transportation and uniform insulation of the line body. At the same time, automatic loading and unloading can also be realized, and the front and rear process conveying lines can be connected. The line body insulation furnace can realize fully automated production with precise control of the conveying tray clamp and the stator, so it has high production efficiency, uniform and long-lasting insulation in a closed environment, and has the characteristics of good product quality, safety and stability.

[0005] The objective of the present invention is achieved through the following technical scheme: an automatic pushing insulation furnace comprises an insulation furnace body and a conveying line body passing through the insulation furnace body and a feeding table and a discharging table at both ends; an insulation air supply device and an exhaust gas collector are arranged on the top of the insulation furnace body; a feeding door is arranged at the feeding end of the insulation furnace body and a discharging door is arranged at the discharging end; a limiting mechanism 1 and a limiting mechanism 2 are arranged on the conveying line body inside the insulation furnace body; a stopper and a pushing mechanism are arranged at the front of the feeding end of the insulation furnace body; a pallet clamp and a stator are transported on the conveying line body. The front and rear parts of the line insulation furnace are equipped with automatic doors, and the front and rear parts of the conveyor line are respectively equipped with a feeding table and a discharging table. A tray roller support frame is arranged inside the furnace body. Combined with some detection components and with the help of the control of the program controller PLC, the preheated stator can be automatically transferred to the next process, and the stator dripped with epoxy resin can be automatically sent back to the curing conveyor line in the line insulation furnace, realizing the fully automated production process of preheating and heat preservation, coating and curing, and dripping and curing to form an insulating layer of the stator, with high production efficiency, good product quality and stable performance.

[0006] Furthermore, in an automatic pushing insulation furnace, both ends of the insulation furnace body are provided with a feed door and a discharge door which are automatically controlled to open. The tray clamp and the stator are automatically positioned and sent into the wire insulation furnace through the limit mechanism 1 and the limit mechanism 2 which are arranged at the predetermined position in the insulation furnace body. The feed door and the discharge door are closed, and a closed space is formed in the wire insulation furnace to insulate and solidify the stator insulation layer. After the insulation and curing are completed, the tray clamp and the stator are automatically output from the wire insulation furnace, completing the fully automated production process with high production efficiency.

[0007] Furthermore, a pallet roller support frame is installed on the conveyor line body inside the insulation furnace body 5 in an automatic pushing insulation furnace. The pallet roller support frame includes a support plate and a rolling bearing. The rolling bearing is attached to the bottom of the pallet clamp to support the pallet clamp and facilitate the movement of the pallet clamp and the stator.

[0008] The effects and benefits of the present invention are as follows: (1) The present invention is an automatic pusher insulation furnace, which preheats stator materials, drips or coats epoxy resin, and then heats and cures them, completing the drip coating and insulation treatment process of the two end faces of the stator. The wire insulation furnace is provided with a feed port and a discharge port at both ends, and is respectively provided with an automatic feed door and a discharge door. Then the conveyor wire carrying the pallet clamp and the stator are transported to the front of the feed port of the insulation furnace through the track, and then the pallet clamp and the stator are sent into the insulation furnace through the pusher mechanism, thereby reducing the workload and working time of the staff in transporting the stator to the insulation furnace, improving the transportation efficiency, and effectively reducing the loss of stator temperature. Moreover, the stator is automatically transferred to the insulation furnace without human intervention, and is automatically output after the insulation and curing is completed, reducing the risk of safety problems. (2) The front and rear ends of the line insulation furnace are equipped with automatic doors, the front of the conveyor line is equipped with a feeding platform and the rear is equipped with a discharging platform. The furnace body of the line insulation furnace is equipped with a tray roller support frame. Combined with some detection components, stoppers and limit mechanisms, and with the help of the control of the program controller PLC, the preheated stator can be automatically transferred to the next process, realizing the fully automated production process of preheating, coating, dripping paint, insulation and curing of the stator to form an insulation layer, with high production efficiency and good product quality.
