1. Product introduction

   The automatic CNC synchronous electronic scale calibration platform is made of metal brackets, fixed It is composed of table top, rotating table top, thrust bearing, universal roller, standard weight, cylinder, geared motor, intermittent control mechanism, electric/pneumatic control system and built-in automatic calibration program and automatic calibration program. The semi-automatic CNC synchronous electronic scale calibration platform has no geared motor and intermittent control mechanism.

   Automatic electronic scale calibration platform, scientifically design and In the production of electronic scales, the processes required for "calibration" and "verification" are integrated. It adopts advanced programmable controller control system and high-speed and reliable electric and pneumatic actuators to complete three-stage calibration and three-stage inspection simultaneously. The operator only needs to put in and take out the electronic scale, and do the corresponding treatment according to the qualified or unqualified directly displayed on the LCD, which greatly improves the production efficiency and product quality. It is very suitable for the needs of enterprises for periodic, large-volume, repetitive electronic scale calibration and metrological verification. Scientific automatic control reduces labor intensity and improves work efficiency. Intelligent measurement technology eliminates human error and greatly improves product quality. The automatic electronic scale calibration platform is a solution for mass production of electronic scales “calibration” and “check”. The automatic electronic scale calibration platform is the result of years of research, design and manufacture of digital electronic scales by Shenzhen Jianda Industrial Co., Ltd. It fully adopts the suggestions of designers and production personnel accumulated in the actual operation process, and uses automatic control technology, measurement technology and software technology reasonably and flexibly to ensure the accuracy and long-term stability of the equipment.

Two, product features  

   1, the operation is simple, the operator only needs to put the electronic scale to be checked Putting in and taking out, the calibration and inspection of an electronic scale is completed.

   2, synchronization processing, the use of synchronization processing technology is an important feature of the device one. Taking the electronic human body scale as an example, there are 6 processes (standard 50KG, standard 100KG, standard 150KG, 40KG inspection, 80KG inspection, 120KG inspection) completed simultaneously.

   3, intelligent diagnosis, automatically determine whether the displayed value of the electronic scale is accurate, and eliminate Manual misjudgment ensures the quality of the product.

   4, flexible and multi-purpose, CNC synchronous electronic scale calibration platform with manual Function. In manual mode, it can be used independently as 6 weighing machines to meet special needs.

   5, digital control, industrial control programmable logic controller (PLC ) And high-speed and reliable electric and pneumatic actuators to replace manual calibration and inspection work.

   6, single operation, 8 procedures (including putting and taking procedures) Only one person can do it independently. It is equivalent to one person operating 6 traditional “weighing machines” at the same time. The significance is especially important in the case of labor shortage.

four, efficacy analysis

    Take a human body scale as an example, use a general electronic scale calibration platform for calibration The process of verifying an electronic human body scale is as follows:

　　一: Calibration

　　Put the electronic scale to be calibrated on the work surface of the electronic scale calibration platform for 3 seconds ;

　　Press the “Start” button for 2 seconds;

　　 automatically load 50.0KG weights, 2 seconds;

　　 after the weight data is stable, complete a period of calibration, 5 seconds;

　　 automatically load 100.0KG weight, 2 seconds;

　　 after the weight data is stable, complete the second stage calibration, 5 seconds;

　　 automatically load 150.0KG weights, 2 seconds;

　　After the weight data is stable, complete the third stage of calibration, 5 seconds;

　　The operator takes out the calibrated electronic scale and puts it on the assembly line for 4 seconds;< /p>

    Two: Check

    Place the electronic scale to be calibrated on the electronic scale calibration platform Work surface, 3 seconds;

    Press the “Start” button for 2 seconds;

    automatically load 40.0KG weight, 2 seconds;

    After the weight data is stable, record the displayed value to determine whether it is out of tolerance, 5 Seconds;

   Load 80.0KG weight automatically, 2 seconds;

    After the weight data is stable, record the displayed value to determine whether it is out of tolerance, 5 Seconds;

    automatically load 120.0KG weight, 2 seconds;

    After the weight data is stable, record the displayed value to determine whether it is out of tolerance, 5 Seconds;

    The operator completes the calibration of the electronic scale, and removes the qualified/unqualified Classified placement, 4 seconds;

From the above process, we can know that the use of a general electronic scale calibration platform can greatly reduce the number of workers Labor intensity. But there are still the following shortcomings:

l  The weights cannot be loaded synchronously and the production efficiency is low. According to the theoretical time, it takes 30 seconds to calibrate an electronic human body scale; it takes 30 seconds to test an electronic human body scale.

l  Calibration and inspection cannot use the same specification equipment, resulting in redundant handling. According to the calibration and inspection process of a typical electronic human body scale, a 3X50.0KG electronic scale calibration platform, a 3X40.0KG electronic scale calibration platform and an assembly line for product delivery are required. Manual handling is required for switching between processes.

l  The product verification results cannot be traced, which may easily lead to wrong judgments and affect product quality.

    The CNC synchronous electronic scale calibration platform adopts synchronous processing technology, and the operator Take the product and load the weight simultaneously. The design can complete the calibration and inspection of a scale in 8 seconds. Thereby greatly improving work efficiency and reducing production costs. The patented technology of inspection data traceability is more effective in product quality control.
