Description

Technical Field

[0001] The utility model relates to the technical field of magnet production, and particularly relates to a cleaning machine for removing glue from neodymium iron boron magnets. Background Art

[0002] Neodymium iron boron, also known as "rare earth neodymium iron boron", is a permanent magnet material with high energy density and one of the permanent magnets with the strongest magnetic properties at present. Its chemical formula is usually expressed as Nd2Fe14B, which is a complex intermetallic compound composed of rare earth element neodymium, iron and boron. Due to its unique high magnetic properties, it is widely used in many fields such as electronics, medical treatment, automobiles, aerospace, etc., such as hard disk drives, power tools, motors, speakers, magnetic sensors, etc.

[0003] During the processing of neodymium iron boron magnetic sheets, wire cutting operation is often required. Wire cutting is a precision machining technology that can cut materials through electric spark discharge and can achieve high-precision and complex shape cutting. For neodymium iron boron with such high magnetic properties, wire cutting can effectively cut large pieces of raw materials into required sizes and shapes to meet the needs of different applications. During the process of wire cutting neodymium iron boron magnetic sheets, it is indeed a common practice to fix large pieces of neodymium iron boron magnetic sheets with glue, especially when the magnetic sheets are thin or small. Glue can help fix the magnetic sheets and ensure that they do not displace or deform during the cutting process, thus improving the machining accuracy. Removing glue and cleaning the cut neodymium iron boron magnetic sheets is an important step to ensure the surface cleanliness of the magnetic sheets and restore their magnetic properties. However, the current common cleaning machines are of pipeline type structure, which occupies a relatively large space, and manual participation is required to transfer the carriers of the cleaning objects during the process, resulting in relatively low efficiency. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a cleaning machine for removing glue from neodymium iron boron magnets, solve the problems of large space occupation and low automation degree of the current cleaning machine, so as to reduce the workload of employees and improve the production efficiency of the cleaning machine.

[0005] The technical solution adopted by the utility model to solve the above problems is: a cleaning machine for removing glue from neodymium iron boron magnets includes an overall machine frame, a controller, a carrier, a transmission mechanism, and a circulation system. A draining station is arranged in the middle of the front of the overall machine frame. The circulation system includes a glue removing liquid cleaning tank and a clean water cleaning tank arranged on both sides of the draining station, and a glue removing liquid circulation tank and a clean water circulation tank arranged on both sides of the back of the overall machine frame. The controller controls the movement of the transmission mechanism. The transmission mechanism drives the carrier to sequentially pass through the glue removing liquid cleaning tank, the clean water cleaning tank and return to the draining station. The glue removing liquid circulation tank is communicated with the glue removing liquid cleaning tank, the clean water cleaning tank is communicated with the clean water circulation tank, and exhaust mechanisms for air extraction are arranged above both the glue removing liquid cleaning tank and the clean water cleaning tank.

[0006] Compared with the prior art, this cleaning machine for degumming NdFeB magnets includes a whole machine frame, a controller, a carrier, a conveying mechanism, and a circulation system.
