[0014] Please refer to Figure 1 and Figure 2 The utility model embodiment comprises:

[0015] A positioning and welding tool for semiconductor sealing tube, the tube body of the semiconductor sealing tube 1 is provided with 5 pipe interfaces 101, one of which is close to the pipe end, and one type of connecting sub-piece 102 and two types of connecting sub-piece 103 are alternately arranged on both sides of the tube body, there are 2 one type of connecting sub-piece 102 and 3 two types of connecting sub-piece 103, the connecting surfaces of all one type of connecting sub-piece 102 are flush, and the connecting surfaces of all two types of connecting sub-piece 103 are flush, the positioning and welding tool for semiconductor sealing tube comprises a bottom plate 2, an end positioning mechanism and a tube body positioning mechanism, the end positioning mechanism comprises an end baffle 3 and an end bracket 4, the top of the end bracket 4 is provided with a placement groove matched with the shape of the tube body, the tube body positioning mechanism comprises 4 longitudinal clamping pieces and 5 horizontal clamping pieces, and a longitudinal clamping piece is arranged between any two adjacent pipe interfaces 101. The two outermost longitudinal clamping pieces are arranged close to the pipe interface positions at both ends of the semiconductor sealing tube. In this way, multi-point positioning support is achieved, and the whole tube body is clamped more stably.

[0016] Each longitudinal clamping piece comprises a bottom support 9 and a longitudinal quick press 10, the bottom support 9 is provided with a groove matched with the shape of the tube body, and the longitudinal quick press 10 is provided with an upper pressing plate matched with the bottom support 9, the horizontal clamping piece comprises a left quick press 14 and a right quick press 12, the left quick press 14 is installed behind the two types of connecting sub-piece 103, the left quick press 14 is provided with a left pressing plate 13, and the shape of the left pressing plate 13 is matched with the connecting surface of the two types of connecting sub-piece 103, the right quick press 12 is installed behind the one type of connecting sub-piece 102, the right quick press 11 is provided with a right pressing plate 11, and the plate surface of the right pressing plate 11 is matched with the connecting surface of the one type of connecting sub-piece 102.

[0017] The bottom plate 1 is also provided with 5 righting structures, the number of the righting structures is the same as and one-to-one corresponds to the number of the pipe interfaces 101,

[0018] The righting structure has two types, one is a pipe body righting structure, and the other is an end head righting structure. The pipe body righting structure comprises a pipe body righting seat 7 and a pipe body righting block 8. The pipe body righting block 8 is fixed on the top of the pipe body righting seat 7. One side of the pipe body righting block 7 facing the pipe interface 101 is provided with a righting groove matching the shape of the corresponding pipe interface. The end head righting structure corresponds to the pipe interface 101 near the end head of the semiconductor sealing pipe 1.

The end head righting seat 6 is arranged on the long edge of the L-shaped end head righting block 5 near the tail part. The righting structure can position the posture of the sealing pipe 1 when the sealing pipe 1 is placed on the tooling, so as to prevent the sealing pipe 1 from being misaligned due to the placing action, thereby affecting the welding precision. Moreover, the righting structure also has a calibration function for the sealing pipe 1 during use. If the sealing pipe 1 placed on the tooling has a size problem, the sealing pipe 1 cannot be completely aligned with all the righting structures. In this way, the unqualified sealing pipe 1 can be quickly screened out before welding. The space between the righting structure near the end head and the end head positioning structure is small. Therefore, the L-shaped end head righting block 5 is designed to meet the righting requirement and eliminate the space contradiction and avoid the end head bracket 4.

The pipe body righting block 7 and the end head righting block 6 are used to correct the placing posture, so that the pipe interface 101 is kept in a slightly leftward inclined state. Then, the handle of the longitudinal fast presser 10 is first lifted, and then the handles of the rightward fast presser 12 and the leftward fast presser 14 are alternately lifted to fix the pipe body in this action state, so as to complete the positioning.
