And bottom plate 51 and mounting panel 52 are in the gliding in-process, and bottom plate 51 is followed to baffle 8 and is slided in step, and bottom plate 51, baffle 8 and chamber door 3 enclose jointly and establish and form the closed side, and the gliding in-process of baffle 8, box 1 and external intercommunication's bore increase gradually, and in this process, the interior high temperature gas of box 1 slowly shifts out through the bore of increase gradually, and operating personnel can be located closed side one side to avoid being scalded by high temperature gas. When the bottom plate 51 is completely slipped out, after the high-temperature gas overflows, the movable rod 93 is driven by the first motor 42 to continue sliding, the box door 3 continues to rotate in the same direction, and the box door 3 rotates 180 degrees, so that the box door 3 is far away from the base 5, at this time, a space is formed between the box door 3 and the base 5 and the baffle plate 8, and an operator can take out the semiconductor chip on the test board 6. The cooperation of all the components in the process does not need to manually open the box door 3 by an operator, the base 5, the baffle 8 and the box door 3 are arranged together to form a closed side, so that the operator can be protected, and the condition that high-temperature gas overflows rapidly through the opening 2 to scald the operator is avoided; in addition, after the base 5 drives the test board 6 to slide out of the box body 1, an operator can take down the semiconductor chip from the test board 6, so that the operator is prevented from being injured by contacting the inner wall of the box body 1 when the semiconductor chip is taken out, and potential safety hazards are reduced.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
