Abstract
Description
Technical Field
[0001] The present application relates to the technical field of infrared detectors, and in particular to a mercury cadmium telluride mother liquor polishing device. Background Art
[0002] Mercury cadmium telluride is a ternary solid solution composed of tellurium, cadmium and mercury. Its band gap can be adjusted by controlling the elemental cadmium component. It is an infrared photosensitivity semiconductor material.
[0003] During the preparation of HgCdTe materials, the mother liquor serves as the foundation for the subsequent growth of HgCdTe crystals or thin films. For example, HgCdTe epitaxial thin films are grown from this mother liquor on a suitable substrate. The HgCdTe mother liquor is reused, so its purity directly affects the cleanliness of the resulting HgCdTe epitaxial thin films. During the HgCdTe growth process, impurities inevitably fall into the mother liquor. For example, graphite components used in liquid phase epitaxy (LPE) drop carbon powder onto the surface of the HgCdTe mother liquor during movement. To address this, the HgCdTe mother liquor ingots must be polished. These impurities are generally less dense than the HgCdTe mother liquor and therefore float to the surface of the liquor, forming a waste layer on the surface.
[0004] The existing polishing method generally involves a worker fixing the mother liquid crystal ingot and then manually rotating a polishing rod to polish its outer surface, which is a relatively low efficiency method. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a mercury cadmium telluride mother liquor polishing device to solve the problem of low efficiency of existing polishing methods.

For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0039] See also Figures 1 to 4 A mercury cadmium telluride mother liquor polishing device provided in an embodiment of the present application includes: a mother liquor fixing component 10 and a polishing component 20; the mother liquor fixing component 10 includes a fixed container 11; the fixed container 11 is used for fixing the mother liquor inside it; the polishing component 20 includes: an end cover 21, a polishing motor 22 and a polishing rod 23; the end cover 21 can movably cover the opening of the fixed container 11, and is used to control the opening of the fixed container 11; the polishing rod 23 can be rotatably set on the end cover 21, and pass through the opening of the fixed container 11 to enter the interior of the fixed container 11; the polishing motor 22 is set on the end cover 21, and the output end of the polishing motor 22 is transmission-connected to the polishing rod 23.
[0040] In this embodiment, the fixed container 11 is a container with an opening, so that the mother liquid can be placed in the fixed container 11; wherein, the fixed container 11 can fix the mother liquid by, for example, snapping, clamping, etc.
[0041] When adding the mother liquid, the end cover 21 can be opened to allow the mother liquid to enter; during polishing, the fixed container 11 can be closed by the end cover 21 to avoid dust diffusion during the polishing process and improve the safety of the polishing process.
[0042] The grinding motor 22 can be a rotary motor, specifically, the grinding motor 22 can drive the grinding rod 23 to rotate to grind the mother liquid. By driving the motor, the grinding efficiency can be effectively improved.
[0043] As an embodiment, the end cover 21 can be slidably matched with the fixed container 11, that is, the end cover 21 can control the opening and closing of the opening of the fixed container 11 by sliding.
[0044] As an embodiment, the end cap 21 is detachably engaged with the fixed container 11. The end cap 21 may be provided with a buckle; the fixed container 11 may be provided with a slot; when the end cap 21 and the fixed container 11 are engaged, the buckle engages with the slot.
[0045] As an implementation, see Figures 1 to 3 , the end cover 21 is hinged to the fixed container 11.
[0046] Specifically, a hinge buckle 28 may be provided on the end cover 21; a hinge ring 14 may be provided on the fixed container 11; during assembly, the hinge buckle 28 is inserted into the hinge ring 14 and passes through the fixing pin, so that the end cover 21 and the fixed container 11 are hinged in a flip-top manner.
[0047] In one embodiment, the polishing rod 23 is arbitrarily mounted on the end cap 21. In this embodiment, the end cap 21 is positioned above the fixed container 11. The arbitrariness of the polishing rod 23 means that when the end cap 21 seals the fixed container 11, the height of the polishing rod 23 can be adjusted vertically. This allows the depth of the polishing rod 23 within the fixed container 11 to be adjusted, thereby accommodating mother liquors of varying sizes and ensuring that the surface of the mother liquor is fully polished.
[0048] In a more specific embodiment, the grinding assembly 20 further includes: a lifting rod 24; the grinding rod 23 is disposed at the bottom end of the end cover 21; the lifting rod 24 can be lifted and lowered at the top end of the end cover 21 and abuts against the grinding rod 23 to drive the grinding rod 23 to lift and lower.
[0049] The lifting rod 24 is used to move the grinding rod 23 up and down, making it easier for the operator to control the height of the grinding rod 23. The top end of the lifting rod 24 extends outside the end cover 21, that is, the top end of the lifting rod 24 serves as its outer end; the outer end of the lifting rod 24 is provided with an operating handle, for example, the lifting rod 24 can be T-shaped, which is convenient for the operator to rotate.
[0050] In use, the grinding rod 23 can rotate relative to the end cap 21 and can also be raised and lowered relative to the end cap 21. The method of arranging the grinding rod 23 to be rotatable and simultaneously raise and lowered relative to the end cap 21 belongs to the prior art. For example, a linear bearing can be sleeved on the outer end of the grinding rod 23, and a rotating bearing can be sleeved on the outer end of the linear bearing to achieve the aforementioned rotatable and simultaneously raise and lower settings.
[0051] In one embodiment, the polishing assembly 20 further includes: a first bearing 25 and an elastic member 26 ; the first bearing 25 is rotatably sleeved on the outside of the polishing rod 23 ; and both ends of the elastic member 26 are respectively connected to the first bearing 25 and the end cover 21 .
[0052] When the polishing rod 23 is pressed down, the polishing rod 23 drives the first bearing 25 to be pressed down, so that the elastic member 26 contracts and stores force. When the lifting rod 24 rises, the elastic member 26 can push the polishing rod 23 to rise.
[0053] It should be noted that the first bearing 25 enables the grinding rod 23 and the elastic member 26 to slide relative to each other, thereby preventing the grinding rod 23 from rotating and driving the elastic member 26 to rotate.
[0054] In one embodiment, a second bearing 28 can be provided in the end cover 21, and the grinding rod 23 is inserted into the second bearing 28 and there is a gap between the second bearing 28, so that the grinding rod 23 can be raised and lowered relative to the second bearing 28. At the same time, when the grinding rod 23 is slightly offset and abuts the second bearing 28 during the grinding process, the end cover 21 can generate relative rotation through the second bearing 28, thereby improving the smoothness of the grinding process of the grinding rod 23.
[0055] In one embodiment, the lifting rod 24 is threadedly connected to the end cover 21 , that is, the relative position of the lifting rod 24 and the end cover 21 is adjusted by rotating.
[0056] In one embodiment, a gear 27 is provided at the output end of the grinding motor 22 ; the gear 27 is meshedly connected with the grinding rod 23 .
[0057] In one embodiment, the mother liquor fixing assembly 10 also includes a plurality of fixing bolts 12; a plurality of bolt holes 13 are provided on the periphery of the fixing container 11; the fixing bolts 12 are passed through the bolt holes 13 and are threadedly connected to the fixing container 11 for fixing the mother liquor in the fixing container 11.
[0058] By adjusting the fixing bolt 12 , the depth of the fixing bolt 12 extending into the fixing container 11 can be controlled to adapt to mother liquors of different sizes.
[0059] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
