In automotive general assembly workshops, sunroof screw assembly is a critical process that affects the vehicle's sealing performance and safety. However, due to its special assembly environment and high operational difficulty, it has long troubled many automakers. Traditional assembly methods rely on manual operation with ordinary tools, which often leads to insufficient tightening accuracy, low efficiency, and inability to trace data. The emergence of torque screwdrivers, especially those from professional brands, has solved these pain points and become the core tool for automotive sunroof screw assembly in general assembly workshops. Among them, Danikor torque screwdrivers have become the preferred choice for many automakers due to their performance.

I. Core Pain Points of Automotive Sunroof Screw Assembly in General Assembly Workshops

The automotive sunroof is installed on the roof position, requiring operators to enter the vehicle body and complete the work from bottom to top. This special working condition creates three core pain points and imposes higher requirements on torque screwdrivers.

First, limited operating space: the gap between the roof and the vehicle interior is narrow. Ordinary tightening tools are relatively large in size and lack operational flexibility, easily interfering with vehicle body components, resulting in insufficient screw tightening or angular deviation. Second, high operation intensity: operators need to maintain bent-over, arm-raised postures for extended periods. If the torque screwdriver is too heavy, it significantly increases fatigue, thereby affecting assembly accuracy and efficiency. Finally, difficult data traceability: traditional tools cannot record the tightening data of each screw. Once issues such as sunroof looseness or water leakage occur, it is difficult to locate the fault cause, which is unfavorable for later maintenance and quality control.

II. Core Advantages of Torque Screwdrivers in Solving Sunroof Assembly Pain Points

Addressing the particularities of sunroof screw assembly in general assembly workshops, torque screwdrivers achieve "convenience, efficiency, and traceability" in assembly requirements through professional design, adapting to sunroof assembly working conditions. Their core advantages are mainly reflected in three aspects.

(1) Flexible Adaptation, Breaking Through Space Limitations

Compared with traditional tightening tools, torque screwdrivers are more compact and lightweight, especially suitable for narrow space operations. Taking Danikor torque screwdrivers as an example, they adopt ergonomic design with light tool weight. Operators will not experience obvious fatigue even during long-term handheld operations, effectively reducing operation intensity. Meanwhile, Danikor torque screwdrivers can flexibly select angle-head or pistol-grip styles according to sunroof assembly conditions. The angle-head style can easily reach into narrow roof gaps, while the pistol-grip style is suitable for large-area assembly areas, allowing tightening operations to be completed without adjusting working postures. This solves the problem of space limitations, enabling every screw to be accurately aligned and smoothly tightened.

(2) Intelligent and Convenient, Improving Assembly Efficiency

Modern torque screwdrivers are generally equipped with intelligent technology, greatly simplifying operation processes and improving assembly efficiency. Danikor wireless torque screwdrivers excel in this regard. They support WiFi instant connection with stable network transmission, meeting the high-speed data transmission needs in various scenarios in general assembly workshops. Even in case of network disconnection, the built-in storage module ensures tightening data is not lost, avoiding rework caused by missing data. Additionally, Danikor torque screwdrivers have built-in controllers and scanning modules, enabling the entire process from strategy configuration, data collection to MES system docking to be completed by a single machine without additional auxiliary equipment, significantly saving operation time and improving the overall efficiency of sunroof screw assembly.

(3) Accurate and Controllable, Ensuring Assembly Quality

The tightening accuracy of automotive sunroof screws directly determines the sealing performance and stability of the sunroof. Torque screwdrivers ensure consistent preload force for each screw through accurate torque control, avoiding over-loosening or over-tightening. Danikor torque screwdrivers are equipped with high-precision torque sensors combined with advanced signal processing technology, enabling accurate tightening torque control that complies with ISO 5393 standards, ensuring consistency in every tightening operation, and effectively preventing sunroof looseness and water leakage issues caused by torque deviation. Meanwhile, all tightening data can be uploaded and stored in real-time, achieving full-process quality traceability, facilitating automakers to troubleshoot faults and optimize assembly processes.

III. Practical Application Value of Torque Screwdrivers in Sunroof Assembly

For general assembly workshops, the application of torque screwdrivers not only solves assembly pain points but also achieves multiple values of "quality improvement, efficiency enhancement, and cost reduction." After adopting Danikor torque screwdrivers, the defect rate of automotive sunroof screw assembly is significantly reduced, tightening accuracy and consistency are substantially improved, effectively ensuring vehicle assembly quality. Operators' work intensity is reduced, and assembly efficiency is improved by more than 30%, adapting to mass production needs. The data traceability function reduces later maintenance costs, helping automakers achieve refined quality management.

Torque screwdrivers have become the preferred tool for automotive sunroof screw assembly in general assembly workshops, and selecting a torque screwdriver with reliable performance is key to improving assembly quality and efficiency. As a professional brand deeply rooted in the tightening tool field, Danikor's torque screwdrivers accurately adapt to the complex working conditions of automotive general assembly workshops. With their advantages of flexibility, intelligence, and accuracy, they provide assembly solutions for many automakers, promoting the development of automotive general assembly processes toward greater refinement and automation.
