Background technology
At present, in the production run of electric core, impermeability to electric core detects the step that is absolutely necessary, existing electric core impermeability detects general mode by negative pressure and detects, its test structure comprises a test bottle, liquid is housed in the test bottle, test bottle connects a vacuum-pumping tube, and its inside is vacuumized, and is inserted with a testing tube in the liquid in the test bottle, the testing tube other end connects electric core, because the negative pressure state in the test bottle, so, can suck air in the testing tube if the impermeability of electric core is bad, inhaled air can produce bubble in liquid, thereby detects the impermeability of electric core intuitively.
But, but the weak point of this device has:
1. the judgement time of low each the electric core of efficient is: 6-10 second, everyone only produces 3600-6000 daily, as in day output 40,000, then needs 6-7 people to finish.
2. labour intensity comparison main point guarantees the accuracy of electric core result of determination, and the employee must firmly compress electric core; Repeat a certain action for a long time and also can make the people feel tired and bored, thereby further reduce work usefulness.
3. the de-stabilising effect of the irrationality vacuum source of control procedure is judged time and result of determination.
Summary of the invention
One of the purpose of this utility model provides a kind of efficient height, little, the rational electric core leak-checking apparatus of control procedure of labour intensity.
To achieve these goals, the utility model adopts following technical scheme:
It comprises one or more test containers, receptacle stand, vacuum solenoid, electric core location-plate, described test container is as on the receptacle stand, the corresponding vacuum solenoid of each test container, each vacuum solenoid one end connection one is used to connect the testing tube of electric core, the other end stretches in the test container, and tested electric core is installed on the electric core location-plate.
Preferably, described electric core location-plate is provided with electric core positioning element, and described electric core positioning element connects a location cylinder, described testing tube connects electric core by sucker, described sucker is located in the push pedal, and described push pedal connects one and drives cylinder, and described driving cylinder is by a frock clamp solenoid control.
Preferably, described vacuum solenoid, frock clamp solenoid valve, location cylinder and driving cylinder connect controller and receive control.
Preferably, described test container is a test tube.
Of the present utility model owing to adopted said structure, can realize detection in batches, realized that electric efficiently core impermeability detects, and after cooperating rational electrical control process, whole location, step such as vacuumize and to carry out automatically, not only further accelerate detection speed, and reduced tester's labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the electric control structure synoptic diagram of the utility model embodiment.
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As shown in Figure 1, embodiment of the present utility model comprises that it comprises one or more test containers 1 that are used to adorn liquid, is used to place the receptacle stand 2 of test container 1, the vacuum solenoid 3 that is used for electric core is vacuumized, electric core location-plate 4 that electric core is laid, described test container 1 is as on the receptacle stand 2, each test container 1 corresponding vacuum solenoid 3, each vacuum solenoid 3 one ends connection one is used to connect the testing tube 5 of electric core, the other end stretches in the test container 1, and tested electric core is installed on the electric core location-plate 4.During use, vacuum solenoid 3 is opened, and extracts the gas of electric in-core to judge the impermeability of electric core in test container 1 by testing tube 5.
Described electric core location-plate 4 is provided with electric core positioning element 41, described electric core positioning element 41 connects a location cylinder 42, described testing tube 5 connects electric core by sucker 51, described sucker 51 is located in the push pedal 6, described push pedal 6 connections one drive cylinder 61, and described driving cylinder 61 is by a frock clamp solenoid valve 62 controls (frock clamp solenoid valve 62, location cylinder 41 and driving cylinder 61 are shown in Figure 2).
As shown in Figure 2, described vacuum solenoid 3, frock clamp solenoid valve 62, location cylinder 41 and drive the control that cylinder 61 connects controllers 7 and receives controller 7.
In use, location cylinder 42 drives electric core positioning element 41 and makes electric core location, drive cylinder 61 and drive the liquid injection port that sucker 51 holds out against electric core, opened 3 pairs of electric wicking vacuum of vacuum solenoid 3 seconds, close frock clamp solenoid valve 62 and stablized vacuum 6 seconds, whether produce bubble in the observation test this moment container 1, judge the impermeability of electric core with this, after detection finishes, close vacuum solenoid 3 backs earlier and open frock clamp solenoid valve 62 reset drives cylinders and location cylinder.
The theoretical production capacity of this electricity core leak-checking apparatus: circulation in 12 seconds, once can detect 5 electric cores, produce 30,000 daily; Ten thousand of actual production capacities=3 * 80%=2.4; By 40,000 electric cores of daily output, then need only 2 people operate two these leak-checking apparatus and can finish; The employee need only upper and lower material, can reduce personnel labor; Process rationally is divided into two stages: inhale vacuum and steady vacuum, can shorten the judgement time like this, also help the consistance of result of determination.
The test container 1 that present embodiment adopted is test tube.
Can realize detection in batches by present embodiment, realized that electric efficiently core impermeability detects, and after cooperating rational electrical control process, whole location, step such as vacuumized and to carry out automatically, not only further accelerate detection speed, and reduced tester's labour intensity.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
