Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and specifically to a cleaning device for grinding workpieces. Background Technology

[0002] Grinding is a common manufacturing process for metal workpieces. It primarily uses grinding machines to shape the workpieces into the desired form. To ensure the cleanliness of the workpiece surface after grinding, the workpiece usually needs to be cleaned and inspected. For example, magnets are generally manufactured using powder metallurgy, and after production, they are ground. During grinding, magnets generate debris, so they need to be rinsed after grinding. However, water stains remain on the surface of the magnets after rinsing. If the workpiece is inspected by the inspection agency while still wet, it will affect the inspection accuracy. Therefore, a drying mechanism is needed to ensure that the workpiece is dried before being inspected, thus guaranteeing the accuracy of the dimensional inspection and ensuring a high pass rate for finished products.

[0003] In the prior art, a drying device is usually set directly after the rinsing module (e.g., Chinese Utility Model Patent "A Grinding Machine Discharge Drying Device", Authorization Announcement No.: CN219890109 U). The workpieces after rinsing are directly put into the drying oven with a lot of water stains, which leads to a long drying time and low production and testing efficiency. Therefore, it is necessary to design a device to achieve efficient cleaning and drying of workpieces after grinding. Summary of the Invention

[0004] The purpose of this invention is to develop a cleaning device for workpieces after grinding, so as to solve the problem of low drying efficiency of workpieces after grinding and cleaning in the prior art, thereby improving the overall production efficiency.

[0005] This utility model is achieved through the following technical solution: A cleaning device for grinding workpieces includes a frame, a rinsing module mounted on the frame, and an oven. The rinsing module includes rinsing nozzles, and a first blowing module is provided between the rinsing module and the inlet of the oven. The first blowing module includes a conveyor belt for transporting the workpiece from the rinsing module to the oven inlet, and a first blowing track that cooperates with the conveyor belt to limit and guide the workpiece. The first air blowing module also includes a first air outlet facing the first air blowing track, and the first air outlet is connected to an air source (including directly installing a fan or blower at the first air outlet, or connecting a fan or blower through an air supply duct).

[0006] The beneficial effects of the above technical solution are as follows: A first blowing module is set between the rinsing module and the drying oven. During the process of the cleaned workpiece being conveyed to the drying oven by the conveyor belt, the first air outlet blows air to remove most of the moisture from the rinsed workpiece. The workpiece after preliminary drying is sent into the drying oven for drying, which can improve the drying efficiency, reduce the drying time, and thus improve the overall production efficiency. The first blowing track is used to determine the transport path of the workpiece and facilitates the setting of the air outlet. The first blowing track also limits and guides the workpiece, so that the workpiece is transported stably under the action of wind.

[0007] In one possible implementation, the first air blowing module includes a first air supply duct connected to a fan, the first air supply duct having a first air outlet facing the first air blowing track, and at least one first air outlet corresponding to both sides of the first air blowing track.

[0008] In one possible implementation, the first air-blowing track includes a first limiting baffle that limits both sides of the workpiece, and a first track air port is provided on the first limiting baffle. The first air outlet faces the first track air port. The airflow blown out of the first air outlet passes through the first track air port and sweeps onto the workpiece to remove moisture from the workpiece.

[0009] In one possible implementation, a second air blowing module is provided at the outlet of the oven. The second air blowing module includes a second air outlet facing the outlet of the oven, and the second air outlet is connected to an air source. The workpiece dried in the oven is cooled by air blowing through the second air blowing module, which can also remove residual moisture, so that the workpiece can quickly enter the next processing step, such as quality inspection.

[0010] Specifically, the second air blowing module includes a second air supply duct connected to a fan, and the second air supply duct has a second air outlet facing the oven outlet.

[0011] In one possible implementation, the frame includes a mounting platform, with the first and second air blowing modules positioned above the mounting platform. A fan is located below the mounting platform, and the first and second air outlets are connected to the same fan via pipes. This structural layout is reasonable and can save space occupied by the equipment.

[0012] In one possible implementation, the rinsing module includes a rinsing track, which includes rinsing limiting baffles that limit the workpiece on both sides. The rinsing limiting baffles have rinsing slots, and the rinsing nozzles face the rinsing slots. When the rinsing nozzles spray water, the water flows through the rinsing slots to clean the workpiece. The rinsing track is connected to a first blowing track.

[0013] In one possible implementation, a material feeding module is provided between the first blowing module and the drying oven. The material feeding module includes a material feeding track connected to the first blowing track and a synchronous wheel assembly located above the material feeding track. The synchronous wheel assembly is driven by a material feeding belt, and the material feeding belt and the material feeding track form a transport space that limits the movement of the workpiece. The material feeding module is used to ensure that the rinsed and preliminarily dried workpiece is stably transported into the drying oven. Especially for workpieces with large weight or volume, it is difficult to ensure the stable movement of the workpiece by simply transporting it by the material feeding track (the conveyor belt of the material feeding track contacts the bottom surface of the workpiece, and the friction force of single-sided contact is small). The material feeding belt also provides a friction force to the upper surface of the workpiece, so that the upper and lower surfaces of the workpiece are subjected to force and can move stably.

[0014] In one possible implementation, the oven outlet is provided with a discharge platform, and the oven further includes a drying track extending from the oven inlet to the discharge platform. The drying track is directly or indirectly connected to the first air blowing track. The drying track limits and guides the workpiece. The drying track sends the workpiece into and out of the oven. After being cooled by air blowing through the second air outlet at the oven outlet, the workpiece enters the discharge platform to wait for the next operation. Attached Figure Description
