Abstract
The invention discloses an automatic testing device and method of a power module. The automatic testing device is provided with a clamp used for fixing the power module to be tested, wherein the clamp is connected with a relay, the relay is respectively connected with different testing devices and is connected with a controller through a serial port or in other modes, and the controller is connected with all the different testing devices. The automatic testing method is characterized in that the relay is jointed, and the controller reads the practical measurement voltage value of a testing point of the power module to be tested and measured by a universal meter; the controller compares the practical measurement value and the allowed range measurement value of the power module to be tested and stored in the controller; and the testing result of the testing point of the power module to be tested is correct if the practical measurement value is within the allowed range measurement value, otherwise the resting result is wrong. According to the automatic testing device and method of the power module, manual wiring and conversion of various states of products to be tested are not needed, work load is reduced, and testing efficiency is improved.
Description
Technical field
The present invention relates to the technical field of measurement and test of circuit board, especially relate to automatic testing equipment and the method for power module.
Background technology
Power module usually makes a mistake when factory testing and actual motion, because components and parts are more in the circuit board of power module, circuit is complicated, searches mistake very difficult.In the prior art, searching by the people is manual of power module mistake tested: the place that contrast may make a mistake, use the testing tool testing power supply modules such as multimeter, oscillograph, test value is analyzed, judged to be within normal scope, thereby find problematic place, the various states that need artificial wiring and conversion tested product during this method of testing test, increased the T.T. of test, test workman's workload strengthens, and production efficiency reduces.
Summary of the invention
In view of the above problems, the invention provides a kind of simple in structure, can reduce cost, automatic test device and the method for testing of the power module of enhancing productivity.
The technical scheme that the automatic test device of power module of the present invention adopts is: the anchor clamps with a fixing tested power module, anchor clamps are connected with relay, relay connects from different testing apparatus respectively, relay connects controller by serial ports or other modes, and controller also connects each different testing apparatus.
Described different testing apparatus is multimeter, oscillograph, programmable power supply and waveform generator.
The technical scheme that the automated testing method of power module of the present invention adopts is: 1) engage relay, controller reads the actual measurement magnitude of voltage of the tested power module test point of multimeter measurement; The size of the allowed band measured value of the tested power module that 2) stores in controller comparison actual measured value and the controller 7; 3) if actual measured value in the allowed band measured value, then the test result of this tested power module test point is " correctly ", otherwise is " mistake ".
The present invention need not the various states of artificial wiring and conversion tested product when test, reduced workload, has improved testing efficiency.Method of testing is simple and reliable, reduces input cost.
Description of drawings
Fig. 1 is the automatic test device schematic diagram of power module of the present invention.
Embodiment
Referring to Fig. 1, the present invention has the anchor clamps 1 of a fixing tested power module, and the power supply that tested power module work is provided is arranged in the anchor clamps 1.Anchor clamps 1 are connected with relay 2, and the relay 2 respectively testing apparatus different from multimeter 3, oscillograph 4, programmable power supply 5, waveform generator 6 etc. connects.Relay 2 connects controller 7 by serial ports or other modes, and controller 7 also connects each different testing apparatus.For common power module, the test point that relates generally to has the parameters such as the frequency, peak-to-peak value of magnitude of voltage, current value, waveform, and these parameters can obtain by controller 7 read test equipment.
By the necessary operating voltage of testing apparatus output, the test of first test point in the beginning power module.For example, adopt multimeter 3 tests, in controller 7, store the allowed band measured value of tested power module, according to the specific requirement of the different test points of power module, the allowed band of measured value is stored in the controller 7 in advance, has for example stored voltage 10V-13V.Engage relay 2, read the actual measurement magnitude of voltage of the tested power module of multimeter 3 measurements by controller 7, and storage, for example the actual measurement magnitude of voltage is 12V.By controller 7 relatively actual measured value (12V) and allowed band measured values (10V-13V), if actual measured value in the allowed band measured value, then the test result of this test point is " correctly ", otherwise is " mistake ".And then carrying out the test of second test point, the test process of concrete test process and first test point is identical, until all test point tests finish.
The testing apparatuss such as 7 pairs of relays 2 of controller, multimeter 3, oscillograph 4, programmable power supply 5, waveform generator 6 read-write control is packaged into and drives layer, the row that drives into that provides according to equipment producer further encapsulates, and has the functions such as normal read-write, mistake processing.To be packaged into the test service layer to the method for testing of all test points of power module, mainly be that needed test point is listed as into inventory sequentially, by the control to relay 2, switch to different test points, finish the test of all test points.The demonstration of test result is packaged into contact bed, test name, test specification, actual test value, the test result of each test point of testing are presented in the interface, like this, for different tested objects (such as 2.4kw power module and 6kw power module), do not need to change all codes, after only the test service layer need to being modified as suitable test point, drive layer and contact bed and need not to change, just can proper testing.The utilization factor of this kind method of testing is very high, and input cost is reduced.
