(2). [Clear Record] Clear all existing records.
During the query, the statistics display three statuses: "OK", "NG" and "Incomplete"; The total number of statistics is the sum of the three;
(3). Each piece product code will generate a record file, which records the screw tightening results of this work.
Please refer to the record file under the record saving path for relevant tightening results.
(9) Waveform comparison
Up to ten waveforms can be selected for comparison, and the waveform type must be the same.
(10) . System Additions
During networking of multiple controllers, different device numbers must be set for different controllers. When changing the device number, the software will automatically prompt whether to continue. It also prompts whether the modification of the equipment number is successful or not.
The saving time and path of work records can be set according to actual needs.
The number and saving path of waveform records can be set.
Note: The waveform record file can only be generated after switching to the waveform display page for waveform record saving; The save path of waveform record file cannot be the same as the save path of work record, so as to prevent the system from deleting the record file by mistake when managing the file.
(11) Task chain management
Task chain management can set one task or multiple tasks in a task chain according to the requirements of the types of screws on the workpiece. Set the number of screws to be tightened for the workpiece. The system will judge whether the workpiece is completed or not according to the set number of screws when working.
Manage task chain related information through "New", "Add", "Delete", and "Modify".
Each task chain can set 8 different or the same execution tasks. The task chain composed of multiple tasks is mainly used in situations where there are multiple screws to be tightened in a workpiece, and the feeder that needs to supply multiple different screws synchronously can give full play to its best performance. Usually, a screw is operated. One task chain only needs to set one task.
(12) . Product Management
Set the corresponding relationship between the product type code and the product, and select the corresponding task chain for work according to different products.
4、 Quick Use Guide
Step 1: Connect the components according to the diagram. The product is designed to be foolproof, and each interface is different, so it will not be inserted incorrectly. Pay attention to the connection between the serial port line and the industrial tablet computer; Remember the serial port number connected to the scanning gun and the serial port number connected to the control cabinet; And the control chassis end shall be switched to PC communication.
Step 2: Open the tightening system software and power on the intelligent electric screwdriver. Select different ports for communication according to the serial port number just connected between the scanning gun and the chassis. The communication baud rate of the scanning gun and the control cabinet is 115200. Click Connect to check whether the communication in the lower left corner is connected normally. If it is abnormal, please check whether the power is on, whether the serial port number is set correctly, and whether the control chassis is switched to PC communication mode. Check whether the products can be scanned correctly.
Step 3: Switch to the "Task Management" module, and set relevant parameters according to the number of screw turns, speed, target torque, etc.
Step 4: Switch to the "Task Chain" module and set the task chain according to the number and type of product screws. Generally, one task chain corresponds to one task.
Step 5: Switch to the "Product Management" module, take one of the products of a certain type and scan the code to register and manage the product QR code. Associate a product type with a task chain. When a product of this type is scanned, the related task chain is automatically executed.
Step 6: Switch to the "Record Display" module, and you can work
The above steps can be fine tuned according to various problems in the tightening process.
