Description

Multi-function automatic testing equipment

The utility model is a kind of multifunctional automatic test system, especially refer in particular to a kind of proving installation of simplifying the electrical function check program that has, the negative section electricity consumption rail of the test board of this device is preset with multistage menopause fate and blocks track every it, test unit by gear start revolution is moved to block track, block and then set test event on the track respectively, the top is placed with treat the measured value of the test unit of electricity measurer to be compared with former established standards value, and be shown in respectively on the instrument panel, measure the quality of electric equipment products with check.

For safeguard the consumer safe in utilization with guarantee product quality, when electric product was made, manufacturer must be through a series of characteristic test, temperature when being grill pan as product, withstand voltage, insulation, heater strip power.The test of projects such as insulation power; Its traditional check program must be set the testing station in regular turn, and product is carried to next testing station again after an individual event functional test is qualified, product is after an individual event functional test is qualified, be carried to next testing station again, treat all items all check meet preassigned after, sale begins to dispatch from the factory; Because the device distribution of each Interventions Requested is not existing together, make the product must be through multiple carrying, during the waste worker and cost very high, the efficient of the control that can't improve the quality.

Because above-mentioned conventional electrical product test system is in design, the defective on the manufacturing technology can't realize multifunctional automatic test, when saving the porter, and the requirement of enhancing productivity.Historical facts or anecdotes has a kind of necessity with the multifunctional automatic test system that improves above-mentioned defective of develop and spread, and the present situation of carrying inconvenience is saved man-hour, the purpose that reduces production costs to reach when checking to improve electric product.

Both deposit defective for what improve traditional manual test board, the applicant has gathered the manufacturing experience of being engaged in this industry for many years, breaks through the restriction of conventional art level, to improve electric product test board checking function, is its purpose.

The application's fundamental purpose ties up in a kind of multifunctional automatic test system is provided, and the electric product checker can finish all tests according to the Interventions Requested of setting in fixed point on oval tester table, to reduce product carrying number of times; When product individual event test number is lower than the established standards value, the buzzer message that just gives a warning on the instrument panel.

Another purpose of the application is to provide a kind of multifunctional automatic test system, and its load can detect according to first article and need do the elasticity setting with the test truncation points and the test unit number of track.

Relevant the utility model is for achieving the above object, and technological means that is adopted and body configuration thereof, feature, purpose, content and function then by cooperating illustrating of embodiment, can obtain more detailed understanding.Shown in the existing adjoint, be described in detail as follows:

Now consult Fig. 1 and 2, be furnished with on the oval board 11 of the utility model multifunctional automatic test system 1 load electricity consumption rail 12, with an annular instrument electricity consumption rail 13, each electric rail 12 is for being set as a plurality of truncation points 121 according to electrical equipment 2 check item numbers, 121 of each truncation points, separate (as shown in Figure 3) with the insulator insulation, and have the standard figures setting of Interventions Requested.

The outer test units 3 that are equipped with equidistant separation of load electricity consumption rail 12 are moved by body gear band action revolution, its top and carry treat that electricity measurer 2(sees Fig. 4); Test unit 3 is the box test cell, one load power source voltage input line and control supply voltage output line (the line footpath is thinner) are arranged, when test unit 3 carrying (for example) grill pans 2 by gear driven during to load electricity consumption rail 12 first truncation points 1211, track bottom brush (14) just conducts to test unit 3 with first truncation points, 1211 Interventions Requested established standards values, this established standards value is compared with the meter reading on the instrument panel 16 again, surmount the established standards value as meter reading, buzzer on the instrument panel is the message that gives a warning moment, as the warning of disqualified upon inspection, remind the reviewer to eliminate this electrical equipment; When it meets setting value, test unit 3 just advances to second truncation points 1212 and does his check, as the temperature of the former setting of present embodiment test grill pan, withstand voltage, insulation, heating power and insulation power etc., make the reviewer can carry out five setting tests (test unit moves to the 5th truncation points from first truncation points) of grill pan in fixed position, with avoid over because of the testing tool facility in different places, must treat the inconvenience of carrying continuously, thereby improve makers' production efficiency.

The number and the functional test project of the truncation points 121 of the utility model load electricity consumption rail 12, all can set different Interventions Requested according to product to be measured functional, make between test unit 3 and test board and have good insulation, its temperature test, the control function process flow diagram, with the guidance panel configuration, built-up circuit figure is shown in annex one to four, when test unit control power supply is the ON state, connect temperature sensor, after electricity is sent in load (electric finished product to be measured), begin heating, temperature rises, pilot lamp is bright to be opened, and load current is to carry through PC plate current transformer (CT), and relay is the state by OFF; When the start of electric product temperature switch (being maximum temperature usually), cut off load power source, current transformer this moment (CT) is output as zero current, relay is transmitted trigger the ON state; Another winding point of relay then is connected to temperature controller " HOLD " input end; in time keep the temperature test value; pilot lamp promptly extinguishes;, go out state bright by pilot lamp are to judge the temperature effect (overheating protection trip-point, reliability, sensitivity, degree of stability etc.) of electrical equipment finished product (as various heating electric appliances articles for use such as grill pan, electronic pot, electric iron, motor stove, electric hot water bottle, the machines of beginning to drink).

The utility model multifunctional automatic test system is made as multi-functional, it is intended to have following function converting unit, as voltage, electric current, electric power, temperature, proof voltage, insulation resistance, resistance (interior resistance or contact resistance), pressure (cooperation pneumatics), rotating speed, frequency, power factor, product electrical endurance, mechanical life etc., its every test wiring such as Fig. 5 (5a, 5b, 5c) shown in:

Wiring diagram when Fig. 5 a is proof voltage, megger test.
