Thus, when two material pipes 90 are inserted into the docking chamber 11 at the same time, the two material pipes 90 are biased by the first pushing assembly 20 and the second pushing assembly 30 and are positioned on the positioning corner structure, so that the two material pipes 90 are stably positioned. Because two material pipes 90 are positioned on the positioning corner structure, the two material pipes 90 are aligned, and therefore when the interfaces of the two material pipes 90 are butted with each other, accurate butt joint of the two material pipes 90 is realized. Because only two material pipes 90 need be inserted into the butt joint cavity 11 of the butt joint body 10, the accurate butt joint of the two material pipes 90 can be realized, the method and the balance capability of the pipe reversing operation are not required, the operation efficiency is effectively improved, the material scattering of the two material pipes 90 is avoided during the pipe reversing operation, and the quality of an IC chip is guaranteed.

The material tube 90 suitable for the auxiliary tool 100 for chip gravity test tube pouring of the present invention is a square tube, but is not limited thereto. Preferably, the positioning corner structure is arranged at a right angle to facilitate the positioning of the material tube 90. For example, the docking body 10 is a square metal tube, but is not limited thereto. The docking chamber in the square metal tube is a square through hole to facilitate the arrangement, but is not limited thereto. The chip gravity test pour tube aid 100 is further described below with reference to fig. 1 to 4.
As shown in fig. 1 to 4, a first inner side surface structure 12 and a second inner side surface structure 13 are disposed in the docking chamber 11, the first inner side surface structure 12 and the second inner side surface structure 13 are perpendicular to each other, and the first inner side surface structure 12 and the second inner side surface structure 13 enclose a positioning corner structure. Therefore, the positioning corner structure is simple in structure and convenient to install and arrange. Specifically, the first pushing assembly 20 is installed on the first inner side surface structure 12, the second pushing assembly 30 is installed on the second inner side surface structure 13, the output end of the first pushing assembly 20 is over against the positioning corner structure, and the output end of the second pushing assembly 30 is over against the positioning corner structure. When the material pipe 90 is close to the positioning corner structure, two adjacent side surfaces of the material pipe 90 are close to the positioning corner structure, and the other two adjacent side surfaces of the material pipe 90 face the first pushing assembly 20 and the second pushing assembly 30 respectively. Thereby facilitating the first pushing assembly 20 and the second pushing assembly 30 to directly push the material pipe 90 to realize the positioning of the material pipe 90. More specifically, the output ends of the first pushing assembly 20 and the second pushing assembly 30 are arranged close to each other, so that the first pushing assembly 20 and the second pushing assembly 30 can act on the butt joint of the two material pipes 90 more powerfully, and the stable butt joint of the two material pipes 90 is facilitated.
