Danikor Smart Electric Screwdriver Anti-Missing Screw Solution

In the manufacturing assembly process, screw tightening is one of the most fundamental and critical procedures. Seemingly simple, if screws are missed, the consequences can range from product function failure and skyrocketing rework costs to equipment malfunctions, safety accidents, and even damage to the company's brand reputation. Especially in precision manufacturing fields like 3C electronics, automotive parts, and medical devices, a single missed screw can cause irreversible losses – for example, a missing screw in medical equipment could affect surgical safety, a missed screw in high-voltage components of new energy vehicles could lead to electric shock risks, and a missed screw in electronic devices could cause component loosening and functional failure. Traditional manual assembly relies on operator experience and attention. Faced with high-intensity, high-frequency tightening tasks, issues like missed or incorrect screws are hard to avoid. Danikor's smart electric screwdriver, with its intelligent control and full-process error-proofing design, has become a core solution to the pain point of missed screws.

Scenario 1: Assembling Multiple Screw Specifications – Job Function Precisely Controls Each Screw

Many product assembly processes require tightening screws of various specifications. Different positions demand different tightening torque and speed requirements. Traditional manual operations can easily confuse specifications and miss screws. The Job function of Danikor's smart electric screwdriver enables precise control of "one parameter per screw", eliminating misses at the source.

The operation method is very convenient: Without complex debugging, simply use the Job function of the smart electric screwdriver to configure independent Pset parameters (covering core tightening parameters like torque and speed) for each screw. Configure the same number of Pset parameters as the number of screws to be tightened.

On the Job operation screen, operators can view the number of screws tightened and the progress in real time. Each time a screw is successfully tightened, the system automatically records it. If the specified number of screws is not completed, the next process cannot be started, preventing misses through workflow control. After all specified screws are successfully tightened, the system will automatically loop the Job, seamlessly connecting to the assembly of the next workpiece, significantly improving production efficiency without needing manual program restart.

For product rework scenarios, the flexible configuration of the smart electric screwdriver effectively addresses pain points. During rework, some screws may already be tightened and do not need repetition. By configuring the button permissions on the Job result screen, operators can directly perform an "increment" operation for already tightened screws, quickly adding the remaining untightened screws. This avoids redundant work while ensuring no screws are missed after rework, balancing rework efficiency and assembly quality.

Scenario 2: Manual Assisted Assembly – Paired with Graphical Guidance Software for Zero-Defect Screw Assembly

The biggest pain points of manual assembly are the susceptibility to errors and difficulty in control. Even when using a smart electric screwdriver, without auxiliary guidance, issues like missed screws, incorrect screws, or wrong bit selection can still occur. To address this, Danikor's intelligent guidance software and supporting equipment form a dual error-proofing system of "electric screwdriver + guidance system + positioning arm", comprehensively preventing assembly errors, especially suitable for flexible production scenarios with small batches and many varieties.

The core advantage of this error-proofing system is "full-process guidance, mandatory verification". Each step has clear prompts to avoid human error:

Material Guidance: Pick-and-place box indicator lights precisely guide the employee to pick up the material of the correct specification. Only by picking the correct material will the system allow the next step, preventing misses or errors caused by picking the wrong material at the source.

Bit Guidance: If the workpiece requires multiple screw specifications, the socket selector will prompt in real-time which bit model to change to next. Only after changing to the correct bit can the smart electric screwdriver start the tightening operation, preventing tightening failure or misses due to mismatched bits.

Screw Inspection: When picking screws, the screw feeder automatically checks the screw length and specification, providing qualified screws in fixed quantities. This prevents unqualified screws from entering the assembly stage and avoids misses due to an insufficient number of screws.

Hole Positioning: During tightening, the positioning arm detects the position coordinates of the current operation in real-time. The tightening tool can only be activated when the screwdriver is aligned with the correct screw hole, preventing misses or errors due to hole position deviation.

Exception Handling: If an NG (e.g., unqualified torque, thread stripping) occurs during tightening, the system immediately issues an audible and visual alarm, prompts the operator to remove the NG screw and place it in a waste collection box, and then automatically provides a new qualified screw, ensuring retightening and preventing misses due to improper NG handling.

Whether for assembling multiple screw specifications or for manual assisted assembly, Danikor's smart electric screwdriver, through flexible program settings and supporting guidance, achieves comprehensive prevention of missed screws. This helps enterprises solve the pain points of manual assembly, fortifies product quality and safety, and seizes a competitive advantage in the wave of smart manufacturing upgrades.
