Description

Technical Field

[0001] This invention relates to the field of bit processing technology, and in particular to an intelligent production line that integrates automatic bit straightening, assembly and testing. Background Technology

[0002] Screwdriver bits are commonly used hardware tools for assembling and disassembling screws. They are widely used in mechanical assembly, home appliance repair, hardware processing and other fields. The market demand is large and they are suitable for mass production processing.

[0003] Traditional bit manufacturing processes often employ a modular approach, where bit feeding, bending detection, pressure straightening, sleeve assembly, and finished product handling and transfer are all independent processes. These processes rely primarily on manual labor and simple equipment to complete the operations step by step. The existing production model suffers from numerous industry-wide shortcomings. Manual material feeding is often disorganized and prone to problems such as jamming, leakage, and excessive material stacking, resulting in poor material supply stability. Detection of bent bits relies heavily on manual visual inspection, leading to low accuracy, numerous missed and false detections, and the inability to identify minute bending defects, resulting in inconsistent straightness of finished products. The manual pressure straightening method for bent bits results in uneven straightening force, poor consistency, and a high scrap rate. Sleeve assembly relies on manual alignment and pressing, leading to large coaxiality deviations, skewing, loosening, and excessive gaps, making it difficult to guarantee product assembly accuracy and consistency. Furthermore, the separate operation of each process and the lack of seamless workstation connections result in significant production waiting time, chaotic production rhythm, low overall production efficiency, high labor intensity, and high labor costs, making it completely unsuitable for the needs of modern mass production of bit manufacturing. Summary of the Invention

[0004] This invention provides an intelligent production line that integrates automatic straightening, assembly, and inspection of bit tools.

After pressing is completed, the cylinder automatically resets, completing a single automated assembly process.

[0039] Please see Figures 1 to 8In one embodiment, the end-feeding structure 5 includes a picking robotic arm 501 and a picking gripper 502. The picking robotic arm 501 is fixedly mounted on one side of the end of the equipment frame 1, and the picking gripper 502 is fixedly assembled at the end of the picking robotic arm 501.

[0040] Working principle and workflow:

[0041] S1. Automatic feeding process: After the equipment starts, the randomly piled bits are collected in the V-shaped hopper 201. The V-shaped structure automatically corrects the posture. The lifting cylinder 202 extends and retracts intermittently. The lifting piston rod 203 drives the lifting plate 204 to rise vertically along the inner wall of the V-shaped hopper 201, pushing the bits out one by one from bottom to top. This achieves automatic feeding and quantitative and orderly feeding. The pneumatic linear drive realizes automated feeding. There is no need for manual sorting and unloading. This effectively avoids the problems of messy feeding, jamming, and leakage. It ensures that the production line feeds continuously, stably, and evenly.

[0042] S2. Automatic workpiece transfer and docking process: After the loading is completed, the three-axis robot 301 drives the robot gripper 302 to move to the loading station through multi-axis linkage servo motion. The gripper uses pneumatic clamping force to stably grasp a single bit. Then the three-axis robot 301 moves to smoothly transfer the bit to the inspection and straightening station and places it in the vertical disc workpiece chuck 304. The three-axis robot 301 achieves automated transfer by moving in space, avoiding collisions and deviations during manual transfer, and providing the basic conditions for subsequent high-precision inspection and straightening.

[0043] S3, Full-range visual bending detection process: After the bit is clamped and fixed, the horizontal moving cylinder 308 drives the sliding base 309 to slide laterally, which drives the vertical disc workpiece chuck 304 and the bit to make fine adjustment and alignment, so that the bit is in the best detection position. Then, the rotary drive motor 303 drives the vertical disc workpiece chuck 304 to rotate the bit 360° in the whole range. The detection sensor 306 and the detection camera 307 synchronously collect the bit rod contour data to identify the bit bending position, bending direction and bending amount in real time.

[0044] S4. Automated pressure straightening process: When the detection system determines that the bit has a bending defect, the equipment automatically enters the straightening process. The limit support block 311 forms a rigid support limit from the underside of the bit bending. The vertical straightening cylinder 312 drives the straightening pressure block 313 to feed vertically downward at a uniform speed, and performs fixed-point pressure correction on the bit bending point, so that the bent rod undergoes a small amount of plastic deformation and returns to a straight state. After the straightening is completed, the straightening pressure block 313 automatically rises back to its original position.

[0045] S5. Multi-station switching and automatic sleeve feeding process: The straightened and qualified bit is transferred by the robot and placed inside the tooling mold 403 of the horizontal rotary assembly turntable 402. The turntable drive motor 401 drives the horizontal rotary assembly turntable 402 to rotate intermittently, driving the tooling mold 403 and bit to the assembly station. At the same time, the vibratory feeder discharge chute 404 realizes automatic sorting and directional conveying of sleeve parts through high-frequency vibration, so that the sleeve slides to the corresponding assembly position of the tooling mold 403, realizing fully automatic sleeve filling.

[0046] S6. Alignment and Press-fitting Process: After the sleeve packing is completed, the angle adjustment cylinder 405 extends and retracts to drive the alignment adjustment rod 406 to push the workpiece, slightly adjusting the assembly angle between the bit and the sleeve to correct coaxiality deviation and ensure coaxial connection. After alignment, the press-fitting cylinder 407 drives the press-fitting head 408 to descend vertically, using constant pressure to complete the press-fitting of the bit and the sleeve, ensuring a tight and secure assembly of the sleeve and the bit. After press-fitting is completed, the press-fitting head 408 automatically resets.

[0047] S7. Finished Product Automatic Picking and Transfer Process: After assembly, the horizontal rotary assembly turntable 402 continues to rotate, transferring the finished workpiece to the end picking station. The picking robot arm 501 moves along the servo, driving the picking gripper 502 to reach the workpiece position, pneumatically clamping the finished product bit, automatically completing the picking, lifting and transfer actions, realizing automatic unloading of finished products, completing a single production closed loop, and a fully automated unloading closed loop, eliminating the need for manual picking and transfer, and reducing labor costs.
