Abstract
The utility model discloses a detecting system, and particularly relates to a system for detecting tightness of bases of hard disks, which comprises a worktable. A fixture is arranged at the upper end of the worktable, and a PLC (programmable logic controller) control device is arranged on a side surface of the worktable. The system for detecting tightness of bases of hard disks is simple in operation, can improve detecting efficiency and detecting quality.
Description
Technical field
The utility model relate to a kind of can detection system, particularly relate to a kind of system that hard disk base sealing detects that is used for.
Background technology
We know; It all is between test article and standard items that general gas leakage detects; Charge into the pressure gas of predetermined pressure simultaneously, it is poor to sense the internal pressure that causes because of leakage through differential pressure pick-up, thereby detects the workpiece leakage rate; This operation of equipment is got up cumbersome, and precision also this is lower.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple to operate that the utility model provides, and high-level efficiency, high-qualityly be used for the system that hard disk base sealing detects.
The system that is used for the detection of hard disk base sealing of the utility model comprises worktable, and the upper end of said worktable is provided with anchor clamps, and the side of said worktable is provided with the PLC control device.
The system that is used for the detection of hard disk base sealing of the utility model, the front end of said PLC control device is provided with counter, and said counter top is provided with pressure display unit, and the upper end of said PLC control device is provided with variable valve.
The system that is used for the detection of hard disk base sealing of the utility model, said worktable is provided with two anchor clamps, and said each anchor clamps are to there being starting switch.
Compared with prior art the beneficial effect of the utility model is: owing to comprise worktable, the upper end of worktable is provided with anchor clamps, and the side of worktable is provided with the PLC control device, like this; Through the setting of PLC control device controlled pressure, when filling into pressure and reach setting value, cut off source of the gas, keep the interior force value of read test article after a period of time; Judge leakage rate through pressure differential, the front end of PLC control device is provided with counter, and the counter top is provided with pressure display unit, and the upper end of PLC control device is provided with variable valve; Reasonable in design, worktable is provided with two anchor clamps, and each anchor clamps is to there being starting switch; Like this, outage rate reduces, and can enhance productivity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail, following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Referring to Fig. 1, a kind of system that is used for the detection of hard disk base sealing comprises worktable; The upper end of worktable is provided with two anchor clamps 4, and 4 pairs of each anchor clamps should have starting switch 2, and the outside of anchor clamps 4 is provided with protective device 5; The upper end of worktable also is provided with emergency stop switch 1 and the reset switch 3 that anchor clamps are resetted; The side of worktable is provided with PLC control device 7, and the front end of PLC control device 7 is provided with counter 9, and counter 9 tops are provided with pressure display unit 8; The upper end of PLC control device 7 is provided with variable valve 6, and the model that PLC control device 7 adopts is NAIS [FPO-21A/FPO-C14CRS/FPO-E16RS].
From the above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
