Description

Technical Field

[0001] The present invention relates to the technical field of superhard materials, and particularly to a device for leveling and capping the raw materials of a diamond composite sheet. Background Art

[0002] With the development of industry and the improvement of residents' living standards, superhard composite sheets synthesized by diamond presses have been widely used in many fields. The superhard composite sheet is first filled with raw materials in a raw material cup, leveled, then covered with a raw material cover, and then subjected to the next processing steps (such as pressure sintering, etc.).

[0003] The existing raw material filling generally uses a fixture to fix the raw material cup, and then manually fills and levels the material; since the raw material is a mixed material of various particle sizes and materials, manual leveling may cause the raw material to be stratified and have a low density, unable to ensure the standardization and uniformity of the filling effect, and thus resulting in unstable quality of the composite sheet after synthesis; in addition, when manually filling with a standard fixture, it is easy to cause the raw material cup to shake, which will also cause the raw material to spill out, resulting in raw material waste and deformation of the raw material cup.

[0004] In the capping process, manual capping is also used. Since the horizontal state of the raw material cup cannot be guaranteed, it is easy to cause uneven stress on the raw material, resulting in different densities in the raw material cup and affecting the quality of the composite sheet after synthesis.

[0005] Therefore, a device that can replace manual labor in the important processes during the filling of the raw materials of the diamond composite sheet is needed. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems and provide a device for leveling and capping the raw materials of a diamond composite sheet.

[0007] The technical solution of the present invention is: a device for leveling and capping the raw materials of a diamond composite sheet, including an operating table, a leveling and capping mechanism, and a pushing mechanism; the pushing mechanism is installed on the operating table, and the leveling and capping mechanism is vertically arranged with the operating table; a leveling station and a capping station are arranged on the operating table; a circular raw material cup is correspondingly placed on the operating table, and a raw material cover is correspondingly arranged on the leveling and capping mechanism; a lifting slide is arranged on the leveling and capping mechanism, and the lifting slide is vertically installed on the operating table; the pushing mechanism includes a telescopic push rod and an arc-shaped positioning plate; the stroke of the telescopic push rod covers the leveling station and the capping station; the arc-shaped positioning plate is fixed at the telescopic end of the telescopic push rod; the arc-shaped positioning plate cooperates with the raw material cup. The raw material cup is placed on the operating table. After filling and leveling, the pushing mechanism pushes it to the next position and then performs the capping operation on it.

[0008] Preferably, the lifting slide table comprises a fixed frame, a driving motor, a transmission belt, a lead screw and a slider; the lead screw is vertically arranged inside the fixed frame and is rotatably connected to the fixed frame at both ends; the bottom of the lead screw is connected to the output shaft of the driving motor through the transmission belt; the slider is arranged inside the fixed frame, the lead screw penetrates through the slider, and the slider is matched with the lead screw through threads; The flattening and capping mechanism comprises a frame, a right-angle reduction motor installed on the frame, a flattening device and a capping device, and the flattening device and the capping device are arranged in parallel in sequence along the extending direction of the telescopic push rod; the frame is fixedly connected to the slider; the flattening device comprises a spinning head and a flattening extension rod, the flattening extension rod is vertically arranged, the top of the flattening extension rod is fixedly connected to the output end of the right-angle reduction motor; the spinning head is fixed at the bottom of the flattening extension rod; the flattening device is correspondingly arranged directly above the flattening station; the rotation diameter of the spinning head at the bottom of the flattening device matches the inner diameter of the raw material cup; the flattening device and the capping device are arranged in parallel, and can push the raw material cup from the position where the flattening device is located to the position where the capping device is located through the action of the telescopic push rod, improving the automation degree of the device and making the capping operation more accurate.

The negative pressure suction cup sucks up the raw material cover, and the upper surface of the sucked raw material cover abuts against the lower surface of the capping sleeve, which can keep the stability and concentricity of the raw material cover.

The push mechanism pushes the raw material cup from the flattening process position to the capping process position, ensuring that the position of the raw material cup is accurate and uniform during capping.

[0013] Furthermore, a guide bearing is provided at the lower part of the fixing frame, and the flattening extension rod passes through the guide bearing, so as to ensure that the flattening extension rod will not have radial runout, thereby ensuring the stability of the rotation of the flattening extension rod.

[0017] Preferably, the edge of the arc-shaped positioning plate is provided with an arc-shaped depression, which matches the outer contour of the raw material cup.
