Description
Technical Field
The utility model relates to the field of fingerprint module testing, in particular to a multifunctional rapid fingerprint module testing intelligent product.
Background
The fingerprint module develops present capacitanc from optics collection module and gathers the module, and the demand volume in market is very big always, and this is also very high to optics and semiconductor module's the foundry output requirement. However, from the mounting of electronic components of products to the gluing assembly, full-automatic or semi-automatic operation is performed, the daily output can reach tens of thousands, but to software burning and function testing, a testing tool is still operated in a manual mode, an operator can perform testing by clicking a mouse operating and controlling a computer step by step, and the daily output is about 1 thousand or even less.
The original method of the existing product burning software is as follows: firstly, connecting a test tool with a computer through a USB, then placing a product module on the tool by an operator, using a thimble to push a test PAD reserved on a product PCB, and then clicking an upper computer of the computer to burn software. After the burning software is finished, the functional test of the product is very troublesome in a factory, time and labor are wasted, the efficiency is low, a large number of testers are arranged to operate each time in order to meet the delivery requirements of customers, and test tools and computers with corresponding quantities are prepared.
SUMMERY OF THE UTILITY MODEL
In view of the defects of the background art, the utility model provides a multifunctional rapid testing intelligent product for a fingerprint module, which can solve the technical problems of manual burning and low testing efficiency of the fingerprint module.
In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a multi-functional quick test intelligence product of fingerprint module, includes MCU, MCU is connected with output interface, communication interface, electric current monitoring circuit, and communication interface is connected with the external computer, and MCU burns record mode or test mode through the instruction of external computer.
Specifically, the MCU is connected with a buzzer, an indicator light and a display screen.
Specifically, the communication interface is a USB interface, and the output interface is a flat cable interface.
Compared with the prior art, the utility model has the following beneficial effects:
1. through the mode of outside computer and MCU intelligence allies oneself with accuse operation, can burn automatically, the automatic test is surveyed the fingerprint module, no longer need artifical click operation according to the step on the computer during burning, no longer need the artifical test fixture that uses step by step operation test of having saved the step of operation computer during the test, save time has improved production efficiency, has solved the artifical technical problem that burns, efficiency of software testing is low of fingerprint module.
2. Mode through the winding displacement interface and the interface high-speed joint of fingerprint module have solved original thimble test fixture contact insecure, complex operation, and the operation is wasted time and energy the scheduling problem.
3. Static power consumption and dynamic power consumption through current monitoring circuit test fingerprint module have saved the step of the operator visual test instrument, and save time has eliminated the possibility of operator reading error.

The utility model has the following drawings:
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
As shown in fig. 1, in the present embodiment:
the utility model provides a multi-functional quick test intelligence product of fingerprint module, including MCU, MCU is used for storing the procedure and burns record through the serial ports, test fingerprint module, MCU is connected with output interface, a display screen, communication interface, output interface is used for connecting the fingerprint module of being surveyed, the display screen is used for showing the project of burning record result and test, the process, the conclusion, communication interface is connected with the external computer and is used for communicating with the external computer, realize alling oneself with accuse operation debugging and test with the external computer intelligence, MCU passes through the external computer instruction and gets into burning record mode or test mode.
MCU is connected with current monitoring circuit for static consumption and the dynamic consumption of test fingerprint module.
The MCU is connected with a buzzer and an indicator light, and the burning result is prompted by using sound and light.
In this embodiment, the communication interface is the USB interface, and the display screen is the LCD display screen, and the output interface is the winding displacement interface, and the winding displacement interface is connected with the fingerprint module that is surveyed and compares thimble test fixture more firm, and the operation is simpler.
In the embodiment, the LCD display screen displays the tested items, the test progress and the conclusion, displays the test step progress in real time, and displays the warning of bad problems.
The working principle and the using process of the utility model are as follows:
the multifunctional rapid testing intelligent product of the fingerprint module is connected with an external computer by using a communication interface;
when in burning, the burning upper computer firstly burns a program into a memory of the MCU, an external computer is operated to instruct the MCU to enter a burning mode, the fingerprint module is connected with the output interface, a serial port of the MCU automatically identifies whether the connection of the fingerprint module is completed, if so, the automatic burning program is started, when the burning is successful, the indicator lamp is bright green or the LCD display screen displays that the burning is successful, the buzzer sounds a sound in a 'dripping' manner, if the burning is unsuccessful, the indicator lamp is bright red or the LCD display screen displays that the burning is unsuccessful, the buzzer sounds a sound in a 'dripping' manner;
during testing, an external computer is operated to indicate the MCU to enter a testing mode, the fingerprint module is connected with an output interface, the output interface supplies power to the fingerprint module, a current monitoring circuit respectively tests static power consumption and dynamic power consumption of the fingerprint module, an ADC (analog to digital converter) functional pin of the MCU detects a monitored current value, a test result is fed back to an LCD (liquid crystal display), the next item is tested continuously after the testing is finished, the MCU continuously tests each function of the fingerprint module through a serial port, if the testing is finished, the testing is fed back to the LCD for displaying, if the testing fails, the testing is stopped, and the LCD displays the reason of the failure;
personnel operation in the burning and testing processes is greatly reduced and simplified, the production efficiency is improved, and the technical problem of low manual burning and testing efficiency of the fingerprint module is solved.
In light of the above, it is clear that many changes and modifications can be made by the workers in the field without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
