Abstract
The invention discloses a thermistor static test sorting machine, comprising a transmission chain, a test piece, a test wheel shaft, a test wheel rotating together with the test wheel shaft and taking a to-be-tested element from the transmission chain to the test piece, and a slicer capable of transferring continuous rotation input into interval rotation and static, wherein the slicer comprises an input wheel and an output wheel which is connected together with the test wheel shaft through a timing belt pulley. The test of the to-be-tested element is changed from a dynamic test into a static test, so that test error produced by relative movement between the to-be-tested element and the test piece is eliminated; and reliability of the test results is increased.
Description
Technical field
The present invention relates to the static testing sorter of a kind of thermistor, belong to field of semiconductor devices.
Background technology
The test of existing thermistor classifier drives testing wheel by main transmission by reductor and realizes.In the existing test structure, because the motion of reductor is continuous, also be continuous by the rotation of the testing wheel of its drive, so the test of detected element is finished, will inevitably cause test error like this under dynamically.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention provides the static testing sorter of a kind of thermistor, and detected element is remained static when test, has increased substantially the reliability of test.
Technical scheme; In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The static testing sorter of a kind of thermistor, comprise: driving chain, test pieces, the test wheel shaft, with test wheel shaft testing wheel that rotate, tested original paper taken to test pieces from driving chain, also comprise and can convert continuous rotation input to rotation at interval and static dispenser, dispenser comprises: power input wheel and go out wheels goes out wheels and is connected as a single entity by synchronous belt and test wheel shaft.
Adopt the said equipment, main transmission is through the power input wheel input of dispenser, and dispenser goes out wheels and drags the test wheel shaft through timing belt pulley, and the testing wheel with the test wheel shaft rotates takes detected element under the test pieces to from driving chain, test when testing wheel is static.
For easy to use, described dispenser is the cam dispenser.
The technology that the present invention does not mention is all with reference to prior art.
Beneficial effect: the present invention is improved to static test with detected element by dynamic test, has eliminated the test error because of detected element and test pieces caused by relative motion, has improved reliability of testing result.Because of control system to the reliability of thermistor and stability requirement very high, manufacturer is in order to reduce test error to the influence of product reliability, often take to same batch the measure of element retest, in actual production, with the method for follow-on test, the erroneous judgement of 1-2 ‰ is often arranged, and after using the method for static test of the present invention instead, repeatedly the element of every batch of 2K-5K is tested repeatedly, all found no erroneous judgement.
Description of drawings
Fig. 1 is the static testing sorter structural representation of thermistor of the present invention;
Among the figure: 1 is the cam dispenser; 2 is power input wheel; 3 for going out wheels; 4 is synchronous belt; 5 is test pieces; 6 is testing wheel; 61 are the test wheel shaft; 7 is driving chain.
The specific embodiment
As shown in Figure 1, the static testing sorter of thermistor, comprise: driving chain 7, test pieces 5, test wheel shaft 61, rotate with test wheel shaft 61, take tested original paper the testing wheel 6 of test pieces 5 to from driving chain 7, also comprise and can continuous rotation input convert the rotation at interval and static cam dispenser 1 to, cam dispenser 1 comprises: power input wheel 2 and go out wheels 3 goes out wheels 3 and is connected as a single entity by synchronous belt 4 and test wheel shaft 61.
Operation principle: adopt the said equipment, main transmission is through power input wheel 2 inputs of dispenser, and dispenser goes out wheels 3 and drags test wheel shaft 61 by synchronous belt 4, with the testing wheel 6 of test wheel shaft 61 rotations, take detected element to test pieces 5 times from driving chain 7, test when testing wheel 6 is static.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
