In today's automotive market, many brands compete to advertise the weight and sturdiness of the body, but the quality of the "weld points" of the body rarely receives attention. Just imagine, no matter how hard a car is, if it lacks good solder joint connection quality, once it encounters an accident, the body may be as vulnerable as "loose sand". So, for the "extremely safe" ARCFOX car, how to ensure the quality of the body connection?
Diversified technology to create quality welding joints
First, let's take a look at the concept of "equivalent solder joints". It does not simply refer to the actual number of solder joints, but is a comprehensive value after comprehensive consideration of the strength and effect of different joining processes (such as solder joints, SPR self-piercing riveting, FDS flow drilling screws, glue connections, etc.).
Take the "indestructible" ARCFOX Alpha T5 as an example, it uses more than 5,200 solder joints on the body, but thanks to the SPR and FDS connection technology specially developed by ARCFOX for the aluminum body, as well as about 125 meters of structural adhesive connection, the ARCFOX Alpha T5 achieves 8,000 equivalent solder joints. In addition, the structural adhesive used in ARCFOX Alpha T5 can reach 25 megapascals, which gives a strong "cohesion" to the body structure of Alpha T5. In addition, ARCFOX Motors has cleverly incorporated a large number of screw joint technologies to add further guarantee to the stability of the body.
Quality assurance: strict monitoring and testing
With so many connection points, how does ARCFOX ensure the quality of each one? The answer is rigorous monitoring and detection. ARCFOX Motors has adopted the triple measure of 100% online monitoring, manual sampling inspection and comprehensive inspection to ensure the foolproof quality of the body connection.
In terms of 100% online monitoring, JiHu Motors is equipped with corresponding testing equipment for each process to monitor each connection point in real time. For example, the spot welding process uses spot welding adaptive technology to monitor each solder joint online; For FDS and SPR processes, each connection point is inspected online through a curve monitoring chart; The gluing equipment uses visual inspection technology to detect the gluing quality in real time. The screwing part uploads torque data through QCOS, and if there is a deviation between the torque and the specified value, an alarm will be issued immediately.
In addition to 100% online monitoring, ARCFOX Motors also conducted manual spot checks. For example, spot welding is manually inspected using ultrasound; The SPR part uses a head hypermeter to check the rivet point; The FDS section is inspected using a sieve ruler; The gluing quality is measured by manually using a steel ruler to measure the length and width of the gluing. The torque of the screw is measured by a staff using a torque wrench. These manual sampling measures further ensure the reliability and accuracy of the connection quality of ARCFOX Automobile's body.
Efficient and intelligent, quality and quantity
Seeing this, we can't help but have another question: there are so many connection points in the car, and so many bodies have to be produced every day, how does Jihu Motors achieve the dual guarantee of quality and output?
In this regard, Jihu said don't worry, let's speak with strength! In terms of hardware investment, ARCFOX has 137 adaptive welding guns, 108 SPR riveting equipment and 22 FDS equipment, and is equipped with 57 automatic gluing machines. These state-of-the-art devices support the precise connection of the car body.
In addition to the hardware equipment, the degree of automation is also the key to the success of JiHu Motors. JiHu has introduced 309 KUKA robots, combined with AGV (Automated Guided Vehicle), APC (Automatic Pallet Change System) and automatic vision guidance technology, to increase the automation rate to 97%.
Despite the high level of automation, ARCFOX Motors has never blindly relied on machines. In order to ensure that the clearance error of ARCFOX does not exceed 1 mm, and the asymmetry error does not exceed 0.5 mm. JiHu has taken multiple safeguard measures. For example, the robot equipment in the ARCFOX Automotive factory has a repeatability of less than 0.1 mm. At the same time, ARCFOX has also implemented three 100% quality control strategies: 100% online measurement of the body-in-white at three key stations; 100% in-line measurement of each cycle of the body-in-white trolley; 100% manual measurement of clearance surface difference at the mass gate. In addition, the staff of ARCFOX Motors will also conduct a random inspection of a full-size body-in-white every day to ensure that the product quality is consistent.
From the carefully selected diversified processes, to the meticulous monitoring and testing process, to the efficient and orderly production process, every link reflects JiHu's determination to pursue the ultimate quality and deep concern for users. ARCFOX Motors is well aware that the safety and luxury of the body are not only reflected in the hardware of the vehicle, but also in the control of every process detail. Therefore, ARCFOX Motors is committed to creating an indestructible protection for the body through exquisite welding technology, and protecting the safety and comfort of every passenger.
