Description

Technical Field

[0001] The utility model relates to the technical field of wafer transport box positioning, in particular to a wafer transport box with a detachable positioning reference. Background Art

[0002] At present, a positioning reference platform (operating platform) is usually set up on the wafer processing production line. A positioning column structure is set on the positioning reference platform, and a positioning reference is set correspondingly on the bottom of the wafer transport box. During processing, the wafer transport box needs to be placed on the positioning reference platform, and the positioning column is inserted into the positioning reference to realize the positioning operation of the wafer transport box. At this time, the distance between the wafer in the wafer transport box and the positioning reference platform is the wafer height. Generally, the wafer height of the first wafer is 44mm (industry standard). Only at this height can the robot arm grab and place the wafer normally. It can be understood that the role of the positioning reference is positioning, that is, to ensure that the wafer height is within the industry standard and its error range.

[0003] The current positioning reference and shell on the wafer transport box are integrated. Due to the large thickness of the positioning reference, shrinkage problems will occur during injection molding, so it cannot be molded in one time. The positioning reference needs to be divided into two parts for secondary injection molding into the positioning reference, and then the molded positioning reference is secondary injection molded into the shell. The process involves two secondary injection moldings, and the position of the positioning reference finally molded in the shell is unstable, which affects the precise position of the box body. Specifically, if one of the multiple positioning references is deformed, the entire box body will be tilted, which has a great impact on the height size of the wafer. In addition, the production process of the above-mentioned positioning reference is complicated and the production efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to address the technical problems existing in the background technology and to propose a wafer transport box with a detachable positioning reference, comprising a box body, a positioning reference is provided on the outer wall of the shell, the positioning reference includes a positioning groove and a guide device, the positioning groove is provided on the box body, and the guide device is detachably connected to the positioning groove.

[0005] Furthermore, the positioning groove is arranged at the bottom of the box body and is integrally formed with the box body.

[0006] Furthermore, the positioning groove includes a first clamping portion, the guiding device includes a second clamping portion, and the first clamping portion is snap-connected with the second clamping portion to achieve a detachable connection between the guiding device and the positioning groove.

[0007] Furthermore, the first clamping portion is a buckle or a slot, and the second clamping portion is a slot or a buckle matching the first clamping portion.

[0008] Furthermore, the positioning groove also includes a positioning body protruding from the box body, and the positioning body is provided with an insertion port at the top.

[0009] Furthermore, the guiding device comprises a mounting port, and the mounting port is used to be connected with the positioning body.

[0010] Furthermore, a guide surface is obliquely arranged at the top of the installation port.

[0011] Furthermore, the positioning body is provided with positioning ribs on the outer side wall, and when the mounting port is connected to the positioning body, the positioning ribs are connected to the inner side wall of the mounting port.

Through the above-mentioned structural arrangement, the present invention reduces the volume and thickness of the positioning reference in disguised form. Specifically, the present invention does not need to injection mold the entire positioning reference and the box body, but only needs to injection mold the positioning groove and the box body as one body, so that the box body can be molded at one time during injection molding. The positioning reference produced in this way has stronger stability and is not easy to deform, which solves the technical problem that "the traditional positioning reference requires the entire positioning reference to be injection molded into the box body, and the thickness of the positioning reference is often large, and it will shrink during injection molding, so it cannot be molded at one time. It is necessary to divide the positioning reference into two parts for secondary injection molding, and then the molded positioning reference is secondary injection molded into a shell, which involves two secondary injection moldings. The position of the positioning reference finally molded in the shell is prone to instability, which has a great impact on the height size of the wafer, and the process is complicated and the production efficiency is low."

Furthermore, the positioning reference of the utility model does not require secondary injection molding during molding, and the positioning reference is less likely to deform, making the positioning of the box body more accurate, thereby ensuring that the wafer can be maintained at a relatively stable height size, while also improving production efficiency.
