AI Technical Summary
Existing silicon core taper testing tools suffer wear due to frequent contact with the conical surface and edges of round silicon cores, resulting in reduced testing accuracy and impacting production quality.
Design a tool for silicon core taper testing. It adopts a structure with a tapered through hole and a rectangular through groove inside the cylinder. The tapered through hole and the rectangular through groove form a base plane and a testing plane, enabling rapid determination of silicon core taper.
This improves the accuracy and stability of silicon core taper detection, reduces tool wear, and ensures production quality.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to detection equipment technical field, concretely for a kind of for silicon core taper detection tool. BACKGROUND
[0002] Round silicon core is the core material for producing high-purity crystalline silicon in photovoltaic and semiconductor industry, and the taper of round silicon core is one of the core parameters of its structural design, which directly affects its assembly accuracy, conductivity and process stability in photovoltaic and semiconductor production.
[0003] The taper C is equal to the ratio of the diameter D of the base circle of the cone and the height L.
[0004] The existing tool for detecting the taper of round silicon core is mainly by sequentially opening the first cylindrical groove 1.1 and the second cylindrical groove 1.2 in the column 1, the diameter of the first cylindrical groove 1.1 is larger than that of the second cylindrical groove 1.2, by inserting the round silicon core into the first cylindrical groove 1.1 and the second cylindrical groove 1.2, by making the taper surface of the round silicon core contact with the two edge edges 1.3 of the first cylindrical groove 1.1 and the second cylindrical groove 1.2, to determine whether the taper of the round silicon core meets the production requirements.
[0005] The problem is that the two edge edges 1.3 are constantly worn out due to the frequent contact of the taper surface of the round silicon core with the two edge edges 1.3, which causes the diameter of the two edge edges 1.3 to increase constantly, reducing the detection accuracy of the taper of the round silicon core and affecting the production quality. UTILITY MODEL CONTENTS
[0006] The utility model aims to provide a kind of for silicon core taper detection tool to solve the problems raised in the above background.
[0007] The utility model is implemented by the following technical solutions:
[0008] A kind of for silicon core taper detection tool, including column, the tapered hole is opened in the column, the bottom opening of the tapered hole is large and the top opening is small, the first rectangular through slot is opened in the bottom of the tapered hole, the second rectangular through slot is opened in the top of the tapered hole, the first rectangular through slot, second rectangular through slot make the column form basis plane and detection plane in turn from bottom to top, and the top surface of the column and the detection plane are silicon core taper qualified area.
[0009] Preferably, the taper of the tapered hole is 1.83 °.
[0010] The utility model has the advantages of simple structure, convenient operation, only need to insert the round silicon core into the tapered hole, and whether the top end of the round silicon core is in the range of silicon core taper qualified area is observed, so that whether the taper of the round silicon core meets the qualified standard of production requirements is quickly judged.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0017] Please refer to Figures 1-4 , the present application provides a kind of for silicon core taper detection tool technical solutions:
[0018] A kind of for silicon core taper detection tool, including cylinder 1, tapered through hole 2 is set in cylinder 1, tapered through hole 2 bottom opening is large top opening small, first rectangular through slot 3 is set in the bottom of tapered through hole 2, second rectangular through slot 4 is set in the top of tapered through hole 2, by first rectangular through slot 3, second rectangular through slot 4 makes that cylinder 1 is formed from below to above in turn base plane 5 and detection plane 6, the top surface of cylinder 1 and detection plane 6 are silicon core taper qualified area between.
[0019] As Figure 4 shown, to meet production needs, it is usually required that the tolerance range of round silicon core taper is 0-0.1mm qualified standard.
[0020] When round silicon core is inserted in tapered surface and just stuck, the diameter of round silicon core, tapered through hole 2 and base plane 5 is D at this time, the distance between base plane 5 and detection plane 6 is L1, and the distance between base plane 5 and the top surface of cylinder 1 is L2.
[0021] Since the taper C = diameter D ÷ height L; if the tolerance range of the taper C is kept within 0-0.1mm, the value of D / L1-D / L2 should be less than 0.1.
[0022] For the present application, D = 16.65mm, L1 = 38.34mm, L2 = 39.9mm, the taper of the tapered through hole 2 is 1.83°
[0023] The working principle is: through the contact of surface to surface, the abrasion of the inner wall of the bottom of the tapered through hole 2 is reduced, so when the round silicon core is inserted in the tapered surface and is just stuck and cannot be loosened, if the taper is small, the length of the round silicon core will exceed the range of the silicon core taper qualified area, if the taper is large, the length of the round silicon core will not enter the range of the silicon core taper qualified area, only when the taper satisfies 0-0.1mm, the length of the silicon core will be in the silicon core taper qualified area, so the rapid detection of the taper of the round silicon core is realized, and the measurement accuracy is stable.
[0024] The above only describes the preferred embodiments of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
