Abstract
The utility model discloses an online test appearance for detecting opto -coupler, including online test appearance body, the luminous control end of the opto -coupler waiting to detect and photic controlled terminal all pass test the appearance body and put through power supply circuit, the photic controlled terminal be connected with the second measuring mechanism that is used for measuring voltage. The utility model discloses the online test appearance has improved the in -house testing of mill effect, improves product quality's reliability and uniformity, and in the testing process, people's variable factor is too many, and product quality can change because of the change of people's variable factor, and this problem has effectively been solved to ICT equipment, makes product quality's reliability uniformity stronger.
Description
Technical field
The utility model relates to air-conditioning production testing instrument field, particularly relates to and can detect the ICT equipment that optocoupler light-receiving end skims pin.
Background technology
ICT (In-CircuitTest) is also known as In-circiut tester, multimeter as powerful in same, open lines, the short circuit of PCB is mainly detected by the test point on test probe contact PCB, the welding situation of all parts, its effect detects the assembly failure occurred when producing PCB, comprise the misloading of components and parts, anti-dress, neglected loading etc. and solder failure, as open circuit, short circuit, account for whole board failure 85%.Can also increase apolegamy configuration, the functional fault of testing circuit plate, such as, detect input, and export, frequency, waveform, logic etc., account for 15% of whole board failure.
ICT testing apparatus is a blind spot for the light-receiving end slash pin of optocoupler all the time, and the optocoupler do not detected rolls off the production line after the load of general assembly complete machine, can affect the first-pass yield of general assembly, and the index of quality of electronics.To analyze the reason that cannot measure of optocoupler be ICT uses the PN junction of test optocoupler luminous end to judge the neglected loading of optocoupler and anti-dress for the test of optocoupler.But optocoupler light-receiving end is without PN junction, so just there will be and skim pin or rosin joint ICT when light-receiving end and judge not situation out, cause general assembly to be rolled off the production line.
Utility model content
Technical problem to be solved in the utility model realizes a kind ofly the light-receiving end of on-line checkingi optocoupler whether to skim the line tester of pin or rosin joint.
To achieve these goals, the technical solution adopted in the utility model is: a kind of In-circiut tester for detecting optocoupler, comprise In-circiut tester body, the light emitting control end of optocoupler to be detected and light controlled terminal all to be switched on power circuit by tester body, and described light controlled terminal is connected with the second measuring mechanism for measuring voltage.
Described light emitting control end is connected with the first measuring mechanism for measuring electric current.
The first described measuring mechanism and the second measuring mechanism are the measuring mechanism of In-circiut tester body.
The first described measuring mechanism contacts two pins of light emitting control end respectively by two thimbles; The second described measuring mechanism is by two pins of two thimble contact light controlled terminals.
The utility model In-circiut tester, improve inside plants test effect, the reliability of improving the quality of products and consistance, in testing process, the variable factor of people is too many, product quality can change because of the change of the variable factor of people, and ICT equipment efficiently solves this problem, makes the reliability consistance of product quality stronger.ICT test is skimmed pin test 100% to optocoupler light-receiving end (3,4 end) and is measured, and compensate for comprehensive spreadability that ICT detects optocoupler components and parts, thoroughly stops to flow into lower operation from mistake.Optocoupler rosin joint, skim pin, leakage, anti-, all can detect, general assembly, without rolling off the production line, reduces manufacturing technology difficulty, promotes manufacturing capacity.The test report of ICT, specific to each bad components and parts, does not need to carry out technician by the bad process of dysfunction analysis device again, greatly reduces the technology needs in production run, promote manufacturing capacity.
Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in the utility model instructions below and figure is briefly described:
Fig. 1 is for detecting the In-circiut tester structural representation of optocoupler;
Fig. 2 is optocoupler Cleaning Principle figure;
Mark in above-mentioned figure is: 1, optocoupler; 2, light emitting control end; 3, light controlled terminal; 4, the first measuring mechanism; 5, the second measuring mechanism.
Embodiment
As Fig. 1, shown in 2, the utility model is the improvement using structure for In-circiut tester (ICT equipment), when detecting optocoupler 1, utilize the power circuit of In-circiut tester body, connect light emitting control end 2 and the light controlled terminal 3 of optocoupler 1 respectively, realize conducting of light emitting control end 2 and light controlled terminal 3, light controlled terminal 3 is connected with the second measuring mechanism 5 for measuring voltage simultaneously, the change in voltage of the second measuring mechanism 5 is observed by the curent change of light emitting control end 2 power circuit, then can detect the light emitting control end 2 of optocoupler 1 and the quality of light controlled terminal 3, effectively the rate that rolls off the production line is reduced like this in quality, improve ICT and try coverage rate, reduce market to roll off the production line.
In addition, the first measuring mechanism 4 for measuring electric current can also be connected with at light emitting control end 2, the convenient curent change observing light emitting control end 2 power circuit, may be used for the data variation comparison with the second measuring mechanism 5, obtains the quality good or not of optocoupler 1 more accurately.First measuring mechanism 4 and the second measuring mechanism 5 are the measuring mechanism of In-circiut tester body, first measuring mechanism 4 contacts two pins of light emitting control end 2 respectively by two thimbles simultaneously, second measuring mechanism 5 is by two pins of two thimble contact light controlled terminals 3, facilitate connection and dismounting, improve detection efficiency.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
