Cognex DataMan 262 barcode readers help you make electronic chips more efficient

With the rapid growth of chips in the electronic semiconductor industry, the requirements for the tracking of chip information are more demanding. The chip sorting equipment of an enterprise company uses a robot to load the material to the sorting equipment, and the chip information in all trays is entered into the database through the code scanning mechanism and then sorted. Because the chip QR code has undergone a number of processes before entering the code scanning process, it is difficult to ensure consistency, so the code reading rate is not high, resulting in a lot of unreadable chips every day, which requires a lot of manual processing. At the same time, because the daily sorting quantity is huge, but the equipment can only read one code at a time, the work efficiency cannot be guaranteed, and if there is a two-dimensional code that cannot be read, the location information also needs to be given, so the function of high-speed group reading needs to be realized. However, high-speed group reading requires multiple barcode readers to realize field of view splicing, because there are too many types of pallets, the script function needs to be edited to realize the output of barcode reading results at the corresponding position, and the installation space is limited, and the external light source cannot be loaded, so the improvement is very difficult.

In order to improve the needs of sorting equipment, a company decided to work together with Cognex products recommended by Xinxiwang to help solve inspection problems. It is required that the supporting barcode reading system on the sorting equipment should meet many requirements: it needs to adapt to the sorting of multiple types of chip trays; The sorting speed and chip information acquisition accuracy are extremely high; If the reading is not successful, the specific location of the chip needs to be fed back in real time for processing, etc.

Faced with the demanding testing requirements of an enterprise company and considering the on-site working conditions, Xinxiwang recommended Cognex's new barcode reading device, the DataMan 262 barcode reader. The superior performance of this barcode reader is as follows:

Achieve high read rates

Combined with patented PowerGrid technology, 2DMax can decode damaged or poorly printed 2D codes, regardless of code quality, printing method, or code surface condition, and can read chip 2D codes with varying consistency after multiple processes.

Simplifies installation in confined spaces

Without a redesign, the 90-degree installation allows four DataMan 262 readers to fit in a small space. The modular lighting and optical path design eliminates the need for additional external light sources, resulting in significant space savings.

Get the best images

The 16mm lens can read small and long working distance chip QR codes. Four high-power red LEDs illuminate the code for better image formation. This feature is particularly useful for long-range code reading and high-speed applications, and the semi-polarized front cover enables more detailed imaging of the QR code outline on shiny surfaces.

Enables quick adjustment of barcode reading parameters

The liquid lens module enables autofocus without moving the sensor position, and the reader automatically optimizes illumination, focus, and illumination scheme for *image formation by pressing the Tune button on the top of the barcode reader.

Flexible scripting capabilities

This enables customers to switch the output format of various pallet reading results, as well as feedback on the reading status of the corresponding position of the chip.

In the actual debug test, the DataMan 262 barcode reader with its powerful PowerGrid decoding algorithm won the trust of an enterprise company with its ultra-high decode rate and compatibility with multiple types of pallets, and only four DataMan 262 barcode readers were used to solve the installation space and high-speed group reading problems.

The optimized workflow is as follows: a stack of trays with chips is placed into the sorting trough by a robot, and the dispatching software switches the output format segments corresponding to the four barcode readers according to the tray type; Four barcode readers on the kinematics receive the trigger signal and simultaneously read the first line of chip code; After the reading is completed, the four readers return the reading results and status of their respective sub-regions; Then the motion device moves the fixed step to read the next line of code; Until the reading of all rows of this tray is completed, the manipulator removes the tray that has been read, and the motion device descends to a fixed height to read the next layer of tray; Repeat until you have read the entire stack of trays.

After using Cognex equipment, it not only promoted the progress of our own production process, but more importantly, greatly increased the output, obtained more orders and customer recognition, which brought great help to our company's new round of production upgrade.
