Technical Field

[0001] The utility model relates to the technical field of chip cleaning process components, in particular to a chip cleaning and corrosion fixture. Background Art

[0002] In the process of liquid phase horizontal epitaxial growth of mercury cadmium telluride infrared detector materials, mercury telluride material chips of a certain size are required.

[0003] At present, the surface treatment of mercury telluride material chips requires organic cleaning, inorganic cleaning and corrosion processes, and a fixture is needed to clean the mercury telluride material chips. However, during the cleaning and corrosion process, the existing fixture is likely to cause the contact surface of the mercury telluride material chip to be not cleaned and corroded, and the surface flatness and glossiness are poor. At the same time, during the cleaning process, it is easy to cause scratches on the surface of the mercury telluride material chip, reducing the cleaning and corrosion yield. Utility Model Content

At the same time, during the cleaning process, the surface of the mercury telluride material chip is easily scratched, thereby reducing the cleaning and etching yield.

[0005] In view of this, the utility model provides a chip cleaning and corrosion fixture, including a base, the base is provided with a strip slot, the inner walls on both sides of the strip slot are provided with a plurality of limiting slots along the axial direction of the strip slot, and the slot structure formed by the limiting slot and the strip slot is adapted to the structure of the chip to be cleaned.

[0006] Preferably, there are a plurality of strip-shaped slots.

[0007] Preferably, the depth direction of the limiting groove is perpendicular to the axial direction of the strip-shaped slot hole.

[0008] Preferably, the groove body of the limiting groove is an arc-shaped structure.

[0009] Preferably, the chip cleaning and etching fixture further comprises a lifting rod, and the lifting rod is detachably connected to the base.

[0010] Preferably, a threaded column is provided at one end of the lifting rod, and the base is provided with a threaded hole threadably connected to the threaded column.

[0011] Preferably, the lifting rod and the base are perpendicular to each other.

[0012] It can be seen from the above technical solutions that the utility model has the following advantages:

[0013] The utility model cooperates the strip slot holes with the limit slot structure so that the strip slot holes penetrate the bottom of a plurality of limit slots, thereby reducing the inertial resistance generated during cleaning. Thus, when the cleaned chip is clamped for dynamic cleaning and corrosion operations, the cleaned chip is always kept in a suspended state, so that the surface of the cleaned chip material is cleaned, flat and bright, and scratches on the surface of the cleaned chip material are prevented during the corrosion process.

[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] At present, the surface treatment of mercury telluride material chips requires organic cleaning, inorganic cleaning and corrosion processes, and a fixture is needed to clean the mercury telluride material chips. However, during the cleaning and corrosion process, the existing fixture is likely to cause the contact surface of the mercury telluride material chip to be not cleaned and corroded, and the surface flatness and glossiness are poor. At the same time, during the cleaning process, it is easy to cause scratches on the surface of the mercury telluride material chip, reducing the cleaning and corrosion yield.

[0023] In view of this, the utility model provides a chip cleaning and corrosion fixture. For easy understanding, please refer to Figure 1 The utility model provides a chip cleaning and corrosion fixture, including a base 11, the base 11 is provided with a strip slot 12, and the inner walls on both sides of the strip slot 12 are provided with a plurality of limiting slots 13 along the axial direction of the strip slot 12. The slot structure formed by the limiting slots 13 and the strip slot 12 is adapted to the structure of the chip to be cleaned.

[0024] There may be multiple strip-shaped slots 12 , and the base 11 may be defined with multiple corrosion cleaning areas, each of which has a strip-shaped slot 12 . In this embodiment, the base 11 has two corrosion cleaning areas.

[0025] In order to clamp and limit the chip to be cleaned, the slot structure formed by the limiting groove 13 and the strip slot hole 12 is adapted to the structure of the chip to be cleaned. At the same time, the depth direction of the limiting groove 13 is perpendicular to the axial direction of the strip slot hole 12 to meet the cleaning requirements of chips of specific sizes.

[0026] At the same time, by providing a plurality of limiting grooves 13, a plurality of cleaned chips can be cleaned in batches at the same time to meet the production requirements of cleaning and corrosion efficiency.

[0027] The chips used in this embodiment include but are not limited to mercury telluride chips. Figure 2 As shown, Figure 2A circular chip is shown. Since most chips are made into a circular structure, in this embodiment, the groove body of the limiting groove 13 is an arc-shaped structure. At the same time, the strip groove hole 12 cooperates with the limiting groove 13 structure so that the strip groove hole 12 passes through the bottom of multiple limiting grooves 13, reducing the inertial resistance generated during cleaning. Therefore, when the cleaned chip is clamped for dynamic cleaning and corrosion operations, the cleaned chip is always kept in a suspended state, so that the surface of the cleaned chip material is cleaned and corroded, smooth and bright, and the surface of the cleaned chip material is prevented from being scratched during the corrosion process.

[0028] like Figure 3 As shown, Figure 3 The structure of the lifting rod is shown schematically. The clamp further comprises a lifting rod 20 , which is detachably connected to the base 11 .

[0029] A threaded column 21 is disposed at one end of the lifting rod 20 , and a threaded hole 14 threadably connected to the threaded column 21 is disposed at the base 11 .

[0030] The lifting rod 20 and the base 11 are perpendicular to each other.

[0031] In actual application, the threaded column 21 of the lifting rod 20 is connected to the threaded hole on the base 11, and then the base 11 is driven to move and the chip to be cleaned is placed on the limiting groove 13 on the base 11. Due to the provision of the strip groove 12, the base 11 will not generate a large buoyancy when placed in the solution for cleaning and corrosion, thereby facilitating the cleaning and corrosion of the chip to be cleaned; after the cleaning or corrosion is completed, the chip to be cleaned can be removed.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
