Why use automatic screw tightening machine?
I. Improving Factory Production Efficiency
1. High-speed Screw Fastening
The working speed of automatic screw tightening machines is much higher than that of manual operations. Generally speaking, a skilled worker using an electric screwdriver may only be able to complete the tightening of 10 to 20 screws per minute, while a well-functioning automatic screw tightening machine can achieve a tightening speed of 40 to 60 screws per minute or even more. In large-scale production, this can greatly shorten the product assembly time. For example, in the assembly lines of electronic device manufacturing factories, such as those for mobile phones and tablet computers, a large number of screws need to be tightened quickly, and automatic screwdriver machines can multiply the production efficiency.
2. Continuous Working Capacity
Automatic screw tightening machines can work continuously for a long time and will not be affected by factors such as the need for rest, meals, or fatigue like human workers. As long as proper maintenance is carried and an adequate supply of screws is provided, they can operate continuously for 24 hours, thus realizing efficient mass production. For factories with large order volumes and tight delivery deadlines, this continuous working ability can ensure that production tasks are completed on time.
II. Improving Product Quality
1. High Precision
Automatic screw fastening machines can ensure that parameters such as the tightening depth and torque of screws are highly consistent through precise program control and mechanical structures. For example, in the assembly process of automobile engines, the tightening torque requirements for screws are very strict. It is difficult to ensure that each screw meets the precise torque standard through manual operation, while automatic screw tightening machines can control the torque error within a very small range, thus ensuring the stability of product quality and reducing product failures or safety hazards caused by improper screw tightening.
2. Reducing Human Errors
During the process of manual screw tightening, problems such as missing screws, stripped screws, and oblique screw tightening are prone to occur. However, automatic screw tightening machines can work under preset programs and strictly follow the specified steps and requirements, avoiding these human errors. This is particularly important for industries with extremely high quality requirements, such as precision instrument manufacturing and medical device manufacturing, and can effectively reduce the defective product rate.
III. Reducing Production Costs
1. Saving Labor Costs
In the long run, the use of automatic screw tightening machines can reduce the reliance on a large number of manual screw tightening workers. Although purchasing automatic screw tightening machines requires a certain amount of equipment investment, as the production scale expands, the savings in labor costs will gradually become apparent. For example, on a production line that originally required 10 workers to perform screw tightening, after using automatic screw tightening machines, only 2 to 3 workers may be needed to operate and monitor the equipment, greatly reducing labor cost expenditures.
2. Saving Material Costs
During the tightening process, automatic screw tightening machines can precisely control the use of screws, avoiding the screw waste that may occur in manual operations. Meanwhile, since they can ensure good tightening quality, they can reduce product damage and rework caused by screw tightening problems, indirectly reducing the waste of raw materials and costs.
