Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, specifically to an automated assembly method and automated assembly line for high shear-resistant rivets. Background Technology

[0002] Rivets are parts that are joined by means of their own deformation or interference fit during riveting. Rivets used in the aerospace field typically employ high shear strength, and their product structure is as follows: Figures 1 to 4 As shown, the components of the high-shear rivet product assembly mainly consist of a mandrel, a ring, and a rivet body. The assembly process relies heavily on manual operation. However, the existing manual assembly method presents the following problems: During assembly, the ring is manually fitted onto the mandrel, the rivet body is screwed into the mandrel, and finally tightened on a drilling machine. The entire assembly process is entirely manual. Due to the uncertainty of operator factors, the actual processing efficiency is very low. Although the assembly action is simple, the tightening process easily leads to the rivet body being tightened too much or too little, resulting in poor product quality consistency and reliability. Furthermore, the assembly process requires multiple operators to work collaboratively according to the assembly steps, resulting in significant manpower consumption and high labor costs. Since this assembly process is labor-intensive, it is difficult to guarantee the high-quality and timely delivery requirements of the product.

[0003] With the development of automation technology, there is an urgent need for an automated assembly line to perform automatic assembly. This can not only improve assembly quality and efficiency and reduce assembly costs, but also reduce the drawbacks caused by human error, greatly reduce the labor intensity of workers, improve assembly efficiency and product quality, thereby improving product production efficiency and meeting the requirements for high-quality product delivery. Summary of the Invention

[0004] The technical problem to be solved by this invention is to address the problems existing in the background technology, thereby providing an automated assembly line with automated loading and unloading. By using automation technology, the assembly of high shear rivets is automated. Automated equipment replaces manual production, shortens the product processing cycle, standardizes standard operations, improves the consistency and stability of product assembly and processing quality, increases product production efficiency, and meets the requirements for high-quality product delivery. Specifically, it is an automated assembly method and automated assembly line for high shear rivets.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automated assembly method for high shear resistance rivets, the automated assembly method comprising the following steps: S1. Start the core rod feeding unit, manually put the core rod into the core rod vibratory feeder feeding device. After vibrating feeding, the core rod feeding robot will clamp the core rod to the assembly unit and place it in the cable nozzle device on the cam divider. The cam divider will drive the cable nozzle device to move to the next processing position and wait for the ring assembly. S2. Start the ring feeding unit. Manually put the ring into the ring vibratory plate. After vibrating and feeding, the ring is pushed to the feeding point by the ring feeding device. Then the ring feeding robot picks up the ring and puts it into the assembly unit. It is placed in the cable nozzle device on the cam divider and assembled with the core rod. After the assembly is completed, the cam divider drives the cable nozzle device to move to the next processing position, waiting for the rivet body to be assembled. S3. Start the rivet body feeding and tightening unit. Manually feed the rivet body into the rivet vibratory feeder. After vibratory feeding, the rivet feeding and tightening robot will clamp the rivet body into the assembly unit and place it in the cable nozzle device on the cam divider. Then, it will be screwed into the mandrel for assembly. The rivet feeding and tightening robot will rotate to tighten and fix the rivet body and the mandrel. During the tightening process, the torque sensor will monitor the torque in real time. Based on the tightening torque, the unqualified products will be screened. Afterward, the cam divider will drive the cable nozzle device to move to the unloading station. S4. Product inspection: The rivet feeding and tightening robot in the rivet body feeding and tightening unit picks up the defective products and places them on the conveyor line in the defective rivet body unloading unit. The defective products are then transported to the defective product box through the conveyor line to complete the rejection of defective products. S5. Start the finished product unloading unit, use the unloading robot to clamp the qualified high shear rivet products and place them in the collection box. After the collection box is full, the products are manually removed, and the automatic assembly of the high shear rivet products is completed.

Firstly, the configuration of a core rod feeding unit, a ring feeding unit, a rivet body feeding and tightening unit, a defective rivet body unloading unit, an assembly unit, and a finished product unloading unit, under the control of a PLC programming control system, utilizes a torque tightening device to effectively solve the problem of core rod wear during product tightening. Secondly, the use of a torque sensor enables adjustable tightening torque and tightening speed, allowing for the adjustment of optimal production parameters based on the product's surface condition. Thirdly, real-time monitoring of the assembly tightening torque replaces manual screening. This system enables the screening of defective products; it utilizes a rivet-loading and screwing robot and a conveyor line to automatically remove defective products, replacing manual selection; it employs a touchscreen in a PLC programming control system to directly retrieve product models, specifications, and lengths through an automated control interface, enabling automatic switching of production programs and significantly shortening product changeover and line changeover times; and it uses servo robots to achieve automatic loading, unloading, and assembly of products. By replacing manual operation with machinery, it achieves automated, unmanned, and manual product assembly, greatly improving working conditions, reducing labor intensity, lowering labor costs, and increasing product production efficiency.

[0016] Therefore, by adopting the automated assembly method and automated assembly line described in this invention, and applying intelligent assembly technology, automated design technology, and PLC automated control technology, the assembly of high shear rivet products can be automated. By replacing manual production with automated equipment, the capacity utilization rate of existing equipment can be effectively improved. This not only improves working conditions and reduces labor intensity, but also enhances the stability and consistency of product assembly quality, increases product production efficiency, and meets the requirements for high-quality product delivery.
