Description

Technical Field

[0001] The present application relates to the technical field of germanium ingot cutting devices, and in particular to a fully automatic cutting device and method for zone melting germanium ingots. Background Art

[0002] In the related art, the general size specifications of zone melting germanium ingots are approximately: upper width: 33.5mm, lower width: 30mm, height: 35.6mm, length 500mm. The production process is: the whole germanium ingot needs to undergo resistivity testing (including weighing, cross-sectional dimension measurement, temperature monitoring, and resistivity testing), and the resistivity unqualified position is determined through the resistivity test, and the unqualified position is marked. After the test, the zone melting germanium ingot is transferred from the test room to the cutting station. The worker first uses a desktop sawing machine to cut off the unqualified resistivity section from the calibrated position, and then cuts off the designated resection section at the tail. The whole germanium ingot is divided into: a resistivity test qualified section, a resistivity unqualified section, and a designated resection section through two cuts. At present, the entire cutting process is completed on a simple cutting device, and the handling, cutting, and partitioning of the zone melting germanium ingot are basically completed by pure manual operation.

[0003] Disadvantages and shortcomings of existing technologies:

[0004] The cutting equipment lacks a precise positioning device for the melting zone germanium ingot, and the cutting position is achieved by manual judgment and adjustment, which is inefficient and of average accuracy.

[0005] The cutting fixture of the cutting equipment is simple and requires manual assistance and tightening during cutting, which has certain safety risks;

[0006] There is no cleaning and drying function after cutting, which may cause waste during transportation;

[0007] The dust collection device generated after cutting is simple, and it is not easy to keep the cutting environment clean and collect dust;

[0059] The fully automatic cutting device for zone melting germanium ingots is a core process in the automatic equipment line for zone melting germanium ingots. A water trough 2 is designed on the lower frame of the device, and a fixed bracket is installed directly above the water trough 2. The fixed bracket is connected to the frame 1. The fixed bracket is equipped with a cutting fixture 10, a cutting protective cover 11, an air knife 12, a cutting support 13, a right end facing knife sensor 14, a left end facing knife sensor 15, and a control motor 16, forming a set of fully automatic cutting fixtures for zone melting germanium ingots that integrate positioning, clamping, cleaning, and drying for cutting zone melting germanium ingots.

[0060] A drainage pipe is installed under the water tank 2 and is connected to the secondary sedimentation tank 3. The wastewater and dust generated by cutting are concentrated in the secondary sedimentation tank 3 for sedimentation and filtration. The filtered water is transported to the water supply component 6 through a water pump for cooling during cutting of zone melting germanium ingots and for cleaning after cutting.

[0061] Directly above the fully automatic cutting fixture for zone melting germanium ingots is the cutting spindle assembly 5, which is mounted on the frame 1. The cutting spindle assembly 5 is composed of a cutting mounting support 51, a servo module 52, a servo motor 53, a water-cooled cutting spindle 55, a saw blade 57, etc. The rear side of the cutting spindle assembly 5 is a synchronous belt conveyor 7, which is mounted on the frame 1 and is mainly used for conveying between the resistivity detection station and the cutting station.

The above components are all installed in the upper frame protection cover, and the upper frame protection cover is installed on the lower frame 1 and the desktop board, forming a complete set of body zone melting germanium ingot automatic cutting device.

[0063] After the resistivity test of the zone-melting germanium ingot, it is transported to the material taking position of the cutting loading and unloading robot 9 through the synchronous belt conveyor 7. The cutting loading and unloading robot 9 grabs the zone-melting germanium ingot to be tested and moves it to and places the zone-melting germanium ingot on the cutting support 13. The cutting fixture 10 clamps the zone-melting germanium ingot and moves it to the left end to face the knife sensor 15.

Before cutting, the water supply assembly 6 is started to flush the cutting position with water and stop after the cutting is completed.

[0064] After cutting, the cutting fixture 10 shifts the cut germanium ingot to the unloading position of the cutting loading and unloading robot 9, and starts the water supply component 6 at the same time to rinse the surface of the germanium ingot. The rinsing is controlled by timing. After the rinsing is completed, the wind knife 12 is turned on to blow dry the cleaned surface of the germanium ingot. The whole process continues until the cutting loading and unloading robot 9 takes away the germanium ingot and stops. The cutting loading and unloading robot 9 transports the dried germanium ingot to the chain conveyor 8, and then resets to the waiting position. Repeat the above actions to complete the unloading of the resistivity qualified section, the resistivity unqualified section and the specified resection section to the chain conveyor 8 in turn, and transport it to the subsequent process through the chain conveyor 8. At this point, the fully automatic cutting of a single germanium ingot is completed.

[0065] A method for fully automatic cutting of zone melting germanium ingots based on a fully automatic cutting device for zone melting germanium ingots comprises the following steps:

[0066] After the resistivity test of the zone melting germanium ingot, the zone melting germanium ingot is transported to the material taking position of the cutting loading and unloading manipulator 9 by the synchronous belt conveyor 7. The cutting loading and unloading manipulator 9 grabs the zone melting germanium ingot to be tested, moves to and places the zone melting germanium ingot on the zone melting germanium ingot automatic cutting jig;

[0067] The fully automatic cutting jig for zone melting germanium ingots is used to position, clamp, clean and dry the zone melting germanium ingots;

[0068] The cutting spindle assembly 5 completes the cutting of the zone melt germanium ingot;

[0069] The zone melting germanium ingot fully automatic cutting fixture moves the cut germanium ingot to the unloading position of the cutting unloading manipulator 9, and starts the water supply component 6 to rinse the surface of the germanium ingot. After the rinsing is completed, the air knife 12 is used to blow dry the cleaned germanium ingot surface;

[0070] The cutting loading and unloading robot 9 transports the dried germanium ingot to the chain conveyor 8, and then resets to the waiting position, repeating the above actions to complete the unloading of the resistivity qualified section, the resistivity unqualified section and the designated cutting section to the chain conveyor 8 in sequence.

[0071] In some embodiments, the rinse water used to rinse the surface of the germanium ingot flows into the water tank 2 and is collected in the secondary sedimentation tank 3. The wastewater and dust generated by cutting are concentrated in the secondary sedimentation tank 3 for sedimentation and filtration. The filtered water is transported to the water supply component 6 by a water pump for cooling during cutting of the zone melting germanium ingot and for cleaning after cutting.

[0072] In some embodiments, the cutting loading and unloading robot 9 grabs the zone-molten germanium ingot to be tested and moves it to and places the zone-molten germanium ingot on the cutting support 13, and the cutting fixture 10 clamps the zone-molten germanium ingot and moves it to the left end facing the knife sensor 15 or the right end facing the knife sensor 14. The cutting fixture 10 is controlled by the PLC electrical control system to clamp the zone-molten germanium ingot for cutting position calibration, and then the cutting fixture 10 completes the clamping of the zone-molten germanium ingot.

[0073] In some embodiments, the cutting position coordinates of the zone melting germanium ingot cutting position calibration are provided by a resistivity measurement platform servo module.
