DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0027] refer to Figure 1 , Figure 2 and Figure 3 As shown, a HJT silicon wafer compatible material box includes a base plate 1, a fixed support seat 2, an adjustable support seat 3 and a hollow structure 4. The compatible material box is used for the placement of silicon wafers 5.

[0028] The bottom plate 1 is provided with a plurality of placement positions for silicon wafers. Preferably, the bottom plate 1 is provided with two rows (in the length direction) and three columns (in the width direction) of placement positions, which can simultaneously hold six silicon wafers. Similarly, the number and arrangement of the placement positions can also be flexibly adjusted as required.

[0029] A silicon wafer support seat is erected on the bottom plate 1 and is located at the side of the placement position. The silicon wafer support seat is used to support and limit the side position of the silicon wafer to ensure the stable placement of the silicon wafer. Specifically, the silicon wafer support seat includes a fixed support seat 2 located on the left and right sides of the placement position and an adjustable support seat 3 located on the front and back sides of the placement position. The bottom plate 1, the fixed support seat 2 and the adjustable support seat 3 form a placement space of a rectangular structure, which is the placement position.

[0030] Both the fixed support seat 2 and the adjustable support seat 3 are plate-like structures, and the vertical surfaces on their inner sides are used to limit and block the silicon wafer. However, the upper parts of the fixed support seat 2 and the adjustable support seat 3 are provided with guide slopes, and the overall guide slopes are trumpet-shaped to facilitate the insertion of the silicon wafer.

[0031] Preferably, the fixed support seat 2 includes a left fixed seat 21 and a right fixed seat 22, the left fixed seat 21 is provided with two spaced apart, and the right fixed seat 22 is provided with two spaced apart, the adjustable support seat 3 includes a front adjustable seat 31 and a rear adjustable seat 32, the front adjustable seat 31 is provided with two spaced apart, and the rear adjustable seat 32 is provided with two spaced apart, the two seats on one side are convenient to arrange, and have a reliable supporting and blocking effect.

[0032] The right fixing seat 22 of the left placement position and the left fixing seat 21 of the right placement position of the two adjacent placement positions on the left and right are of the same structure. The use of this structure can achieve dual-purpose use of one seat, reduce the arrangement of one fixing seat, and thus save overall cost investment.

[0033] The adjustable support seat 3 is arranged on the bottom plate 1 so as to be adjustable in sliding along the front-back horizontal direction. The front-back direction is the length direction. The adjustable support seat 3 can accommodate the placement of silicon wafers of different specifications (mainly different lengths) by adjusting the front-back position.

[0034] The bottom plate 1 is provided with a slide groove 33 arranged along the front-to-back horizontal direction. The slide groove 33 is a rectangular structure. The bottom of the adjustable support seat 3 is integrally provided with a slider 34. The slider 34 is also a rectangular structure. The slider 34 is slidably arranged in the slide groove 33, thereby realizing the sliding adjustment of the adjustable support seat 3.

[0035] There are many ways to temporarily lock the adjustable support seat 3. Figure 4 As shown, the slide groove 33 and the slider 34 are interference-fitted, and the seat body is fixed by the friction force generated by the extrusion between the slide groove 33 and the slider 34. When adjusting the seat body, it is necessary to overcome the friction force. For another example, a locking screw is threadedly connected to the slider 34, and the locking screw is in contact with the bottom plate 1. By tightening the locking screw and pressing the bottom plate 1, the seat body is fixed by the friction force between the locking screw and the bottom plate 1. When adjusting, the locking screw can be loosened.

[0036] The bottom plate 1 is provided with a hollow structure 4 located at the side of the placement position. The hollow structure 4 facilitates the placement and operation of the silicon wafer by passing the fingers through the hollow structure 4 instead of against the bottom plate 1. The hollow structure 4 includes a left hollow 41, a right hollow 42, a front hollow 43 and a rear hollow 44 located in the four directions of the placement position, so that the silicon wafer can be easily placed and taken in four directions without being restricted by the direction.

[0037] The hollow structure 4 is located at the interval between the fixed support seat 2 and the adjustable support seat 3 to prevent the upright seat from blocking the hollow structure 4 and affecting the normal placement. The right hollow 42 of the left placement seat and the left hollow 41 of the right placement seat in the two adjacent placement positions are through structures, and the rear hollow 44 of the front placement seat and the front hollow 43 of the rear placement seat in the two adjacent placement positions are through structures, which are convenient for overall processing and manufacturing.

[0038] The compatible material box adopts a simple design principle to solve the problems of personnel waste and object damage. The simple design does not require changes to the equipment structure, is easy to install, and solves work difficulties with low investment cost.

[0039] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
