PURPOSE:To improve yield rate and work efficiency in a glass tube supply jig for glass sealed diode assembly by disposing a storing hole group on the main surface of a loader corresponding to a supply portion in such a manner that the countersink of the storing hole is brought into contact with an adjacent counter sink with a small expansion angle. CONSTITUTION:The main surface of a glass loader 9 is provided with the first group A of storing holes 12 arranged in zigzags and the second group B of storing holes 12 arranged in such a manner as to supply a glass tube to a support hole which is not supplied by the first group A. The opening angle theta2 of the countersink 18 of the storing hole 12 is 40 degrees to be in contact with the edge of an adjacent countersink 12. In this arrangement, the diameter of the countersink 18 is larger than conventional one and the grade is severe, so that at the time of supplying a glass tube to a support hole from the group A and the group B, the glass tube is easy to go into the countersink 18. Accordingly, the charge time is shortened, and damages of parts can be reduced so as to improve work efficiency and yield rate. |
