In practical application, the automatic identification mechanism may use a PC as a carrier, and install special software to implement the functions of the processing unit and the control unit, i.e. to control the motion of the transmission rail mechanism and the XY-axis motion mechanism. Specifically, an XY two-axis motion platform is adopted, and a servo motor and a ball screw are adopted to execute motion.

The dotting mechanism comprises a seal type pen point, and the pen point is a seal type pen point customized according to the characteristics of a product position, the size of a blank area and the like, and can be used for regularly adding fast dryable red ink into the pen point. The nib passes through the retractable cylinder and connects, when receiving the mark command of dotting, through the flexible execution action of dotting repeatedly, realizes the accurate sign to NG product.

In addition, the dotting mechanism can further comprise a positioning device, wherein the positioning device is arranged near the stamp head and is mainly used for realizing startup calibration and determining the current position of the dotting mechanism in the subsequent process. Specifically, the positioning device is used for calibrating the target substrate according to a reference point preset on the target substrate when the mobile phone is started for the first time in class (day); the positioning device is further used for determining the current position of the dotting mechanism in real time and sending the current position to the control unit, so that the control unit can judge whether the XY-axis movement mechanism needs to be controlled to move continuously or not according to the current position of the dotting mechanism, when the current position of the dotting mechanism corresponds to the position coordinates of the NG product element in the local coordinate system, the XY-axis movement mechanism does not need to be controlled to move, and then the dotting mechanism is further controlled to perform marking action.

In practical application, the laser guide device can be selected as the positioning device, and the CCD visual positioning mechanism can also be used as the positioning device, so that the accuracy of the NG product element position identification is further improved.

In addition, the automatic identification mechanism further comprises an underframe mechanism, and the underframe mechanism is located below the transmission track mechanism and used for fixing the transmission track mechanism. The chassis mechanism is shown in fig. 9, and the correspondence between the reference numbers and the parts in fig. 9 is shown in table 5:

The upper surface of the chassis mechanism is provided with a first in-place sensor and a first lifting cylinder, and the upper surface of the first lifting cylinder is further provided with a blocking and stopping module.

In practical application, after the first in-place sensor detects that the transmission track mechanism basically conveys the target to the target position through the workbench, a first lifting command is generated and sent to a first lifting cylinder, and then the first lifting cylinder controls the gear stopping module to lift according to the first lifting command.

The stop module is mainly used for ensuring that the position of the substrate to be detected is fixed every time. The stop module is arranged on one side of the underframe mechanism, which is far away from the AOI equipment, namely right in front of the transmission direction of the workbench. The stop module is located below the horizontal plane of the transfer rail when descending and above the horizontal plane of the transfer rail when ascending, so that the target substrate is stopped. In fact, the stop module is formed by connecting a first lifting cylinder with a sheet metal part, and the first lifting cylinder is fixed on the chassis mechanism. The lifting of the gear stopping module is controlled by a first lifting cylinder, and the first lifting cylinder is mainly controlled by signals of a first in-place sensor.

The upper surface of the chassis mechanism is also provided with a second lifting cylinder and a second in-place sensor.

In practical application, after the second in-place sensor detects that the gear stop module rises, a second rising instruction is generated, and the second rising instruction is sent to a second rising cylinder, and the second rising cylinder controls the workbench to rise according to the second rising instruction. The lifting of the working platform is controlled by a second lifting cylinder which is mainly controlled by the signal of a second in-place sensor.

It will be appreciated that the automatic identification mechanism may also include a network transceiver module. The processing unit may obtain a high-definition thumbnail, i.e. a substrate image, from the database of the AOI device by using the network transceiver module, and determine the position coordinates of the NG product component on the target substrate in the AOI device coordinate system according to the high-definition thumbnail.

The operation of the automatic identification mechanism will be described below.

Assuming that 400 test strips are arranged on each substrate, items to be detected and threshold values are set during programming, the AOI equipment detects whether each product component is NG or not according to the setting, and if the threshold values are exceeded, the AOI equipment is NG (unqualified), and the AOI equipment outputs the detection result.

The automatic identification mechanism is used as downstream equipment of the AOI equipment, and the automatic identification mechanism and the AOI equipment communicate with each other through an international general SMEMA protocol. After AOI equipment detects and finishes, automatic identification equipment can send the board signal to AOI equipment under idle state, then the base plate passes through the gyro wheel belt and is conveyed automatic identification equipment by AOI equipment, rises to keep off and stops module and workstation. It is worth mentioning that only when the automatic marking device is idle, the target substrate on one side of the AOI device can flow into the automatic marking mechanism, and if the substrate on one side of the automatic marking mechanism has incomplete marks, even if the front-end AOI device has already been detected, the target substrate can only be in standby, otherwise, the stacking is caused.

Because the automatic identification mechanism is not provided with a vision-free mechanism, the automatic identification mechanism and the AOI equipment share one database entity (Mysql database), a high-definition thumbnail output by the AOI equipment is read in a network communication mode, the position coordinate of the product element under the AOI equipment coordinate system can be determined according to the high-definition thumbnail, and the position coordinate of the product element under the local coordinate system is obtained.

The high-definition thumbnail refers to that the AOI equipment mainly uses the substrate image as a basis when judging whether a product element is NG or not for the collected substrate image. During the operation of the AOI equipment, the AOI equipment can self-name each product component, and a coordinate system is established by using a fixed reference point on the substrate, so that all the product components on the substrate have independent position coordinates. After the base plate is detected by the AOI equipment to finish the output result, the base plate is transmitted to the automatic identification equipment locally, and the stop module is jacked up with the workbench, so that the position to be detected where the base plate stays every time is fixed. And then, calibrating the automatic identification mechanism by using the same reference point, establishing a local coordinate system of the automatic identification mechanism, and determining the corresponding relation between the coordinate system of the AOI equipment and the local coordinate system through software to obtain the position coordinates of all product elements on the substrate under the local coordinate system.

After receiving the detection result of the AOI device through software, the worker at one side of the automatic identification device may further check the detection result, for example, display a local enlarged detail drawing at the PC end, directly confirm whether each product component is an NG product component or confirm an NG type through the PC end, and issue a dotting request to the automatic identification mechanism after confirming that it is an NG product component. Then, the controller generates a moving instruction according to the position coordinates of the product element in the local coordinate system and sends the moving instruction to the XY-axis motion mechanism; meanwhile, the controller generates a dotting instruction and sends the dotting instruction to the dotting mechanism. The dotting mechanism is carried by a gantry type cantilever mechanism driven by double motors to move left and right, and a steel seal type dotting head and a weak current driven laser positioning head are designed at the top end of the dotting mechanism and used for NG identification and positioning.

It is understood that the dotting operation may also be performed directly according to the detection result of the AOI device without manual confirmation.

To sum up, the overall work flow of the automatic identification mechanism is as follows: when the automatic identification equipment is idle, a plate-requiring signal is sent to the AOI equipment, the AOI equipment automatically scans and calculates and outputs a high-definition thumbnail, the automatic identification equipment reads the high-definition thumbnail in a network sharing mode, then, according to the detection result of the AOI equipment, a dotting action is carried out on NG product elements, subsequent procedures are conveniently screened, and the identification is automatically transferred to the next procedure (such as a fitting procedure) through a track after being completed. And then, sending a plate requiring signal to the AOI equipment to realize automatic streamlined operation.

It can be seen that the automatic identification equipment that this application provided has realized replacing artifical manual sign to the automatic sign of NG product component, has realized following technological effect:

production efficiency is improved, the front-end AOI equipment is butted, NG product point positions are automatically read to realize automatic identification, positions do not need to be checked manually one by one, and manual identification is not needed;

quality of guarantee is controlled, and product NG sign position is less, and personnel's manual red pen sign is unstable, thereby easily draw the normal product in next door of polluting, and manual sign elbow and clothing contact other positions of base plate easily and cause secondary damage. The automatic identification equipment accurately marks according to the position coordinates of the NG product elements, is high in operation accuracy, improves the marking accuracy, and avoids interference with other product elements;

the working strength of the staff is reduced, the staff does not need to carefully check under a bright fluorescent lamp for a long time by adopting an automatic identification mechanism, and the fatigue degree of the eyes of the staff is reduced.
