Abstract
The utility model discloses an automatic feeding vacuumizing encapsulation structure. The automatic feeding vacuumizing encapsulation structure includes an upper mold (6) and a lower mold (7); the upper mold (7) is connected with the lower end of an upper electrode rod (2) through a nut; the upper electrode rod (2) is sleeved with a vacuumizing cover (4); the vacuumizing cover (4) is connected with driving devices (1) through a fixing plate (3); and the driving devices (1) can drive the vacuumizing cover (4) to move up and down. With the automatic feeding vacuumizing encapsulation structure of the utility model adopted, the resistance of a quartz crystal resonator after encapsulation can be decreased, and therefore, the DLD2 of the quartz crystal resonator can be effectively improved, and the qualified rate of finished products can be increased significantly, and at the same time, nitrogen can be saved.
Description
Technical field
The utility model relates to a kind of automatic charging and vacuumizes encapsulation.
Background technology
The conventional package form of quartz-crystal resonator is that thousand devices are placed in magazine and vacuumize together, is then filled with nitrogen, and another welds encapsulation, resistance, DLD2 after wayward like this encapsulation, and the nitrogen amount of expending is large.
Utility model content
The purpose of this utility model is to solve the problem that resistance is bad, DLD2 is bad causing in encapsulation process.
The technical solution adopted in the utility model is: automatic charging vacuumizes encapsulation, comprise mold and bed die, mold is connected to top electrode bar lower end by top nut, top electrode bar overcoat evacuated housing, evacuated housing is connected with drive unit by fixed head, can drive evacuated housing to move up and down.
As further improvement of the utility model, the limit that evacuated housing moves down is and lower nut contact-making surface place.
As further improvement of the utility model, drive unit is oil cylinder or cylinder.
The beneficial effects of the utility model are: the utility model has reduced the resistance of quartz-crystal resonator after encapsulation, has effectively improved DLD2, and finished product qualification rate obviously rises, and saves nitrogen simultaneously.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 drive unit, 2 top electrode bars, 3 fixed heads, 4 evacuated housings, 5 top nuts, 6 molds, 7 bed dies, 8 lower nuts.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.
As shown in Figure 1, the present embodiment comprises mold 6 and bed die 7, and mold 7 is connected to top electrode bar 2 lower ends by top nut 5, top electrode bar 2 overcoat evacuated housings 4, evacuated housing 4 is connected with drive unit 1 by fixed head 3, can drive evacuated housing 4 to move up and down.
The limit that evacuated housing 4 moves down is and lower nut 8 contact-making surface places.
Drive unit 1 is oil cylinder or cylinder.
The vacuum chamber of folding up and down of the utility model design specialized, utilizes vacuum pump to vacuumize the vacuum chamber that has a crystal resonator in closing, and exhausts directly encapsulation after vacuum, no longer carries out inflated with nitrogen.
Below by reference to the accompanying drawings execution mode of the present utility model is described, but the utility model is not limited to above-mentioned execution mode, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
Claims (3)
1. automatic charging vacuumizes encapsulation, it is characterized in that comprising mold (6) and bed die (7), mold (7) is connected to top electrode bar (2) lower end by top nut (5), top electrode bar (2) overcoat evacuated housing (4), evacuated housing (4) is connected with drive unit (1) by fixed head (3), can drive evacuated housing (4) to move up and down.
2. automatic charging according to claim 1 vacuumizes encapsulation, it is characterized in that the limit that described evacuated housing (4) moves down is and lower nut (8) contact-making surface place.
