Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, specifically a screw machine. Background Technology

[0002] Currently, in manufacturing industries such as component connection, electromechanical, and toy furniture, there are high requirements for structural robustness. Therefore, screw assembly is widely used. In the past, screw assembly was mostly done manually, with screws placed into screw holes by hand. However, some parts have complex internal structures with limited space and deep locking positions. When manually tightening screws, it is difficult to distinguish the screw hole positions and the tightening effect, resulting in low work efficiency. This is not conducive to the expansion of enterprise production scale and the improvement of production efficiency.

[0003] To improve efficiency, existing production lines mostly use screw machines for screw assembly. Screw machines can automatically pick up materials from the hopper and tighten the screws in the required position using an electric screwdriver. Although they can efficiently complete the picking and tightening work, they still have many shortcomings in workpiece loading and unloading. Although existing screw machines have conveyor belts to assist in material handling, considering material blockage and unstable supply demand, manual intervention is still required for material supply. The material supply efficiency is low and the material buffering function cannot be achieved, resulting in poor work stability. Therefore, a screw machine is proposed. Utility Model Content

[0043] Working principle or structural principle: During operation, the material in the carrier is fed into the device through the feed port of the frame box 1. After being fed in, the carrier is supported by the conveyor belt and installed on the upper part of the streamline conveyor seat 17. After being conveyed by the streamline conveyor seat 17, the carrier flows into the buffer station on the left. According to the supply demand, it can be buffered offline or directly flow into the working station at the rear. When buffering the carrier, the stop plate 21 moves up under the drive of the stop drive cylinder 20 to stop and limit the carrier. Then, under the drive of the carrier lifting cylinder 18, the carrier lifting plate 19 lifts the carrier and presses it under the dust cover plate 22. Then, the first carrier support block 24 is laterally slid driven by the first support block drive cylinder 23. The first carrier support block 24 supports and limits the end side of the carrier. After completion, the stop plate 21 and the carrier lifting plate 19 move down to reset, which will not obstruct the subsequent conveying of the carrier, thus completing the offline buffering of the carrier.

[0044] The subsequent carrier is conveyed into the working station via the streamlined conveyor 17. To improve processing efficiency, the carrier prioritizes entering the right-side working station during supply, enabling simultaneous processing by two sets of intelligent electric screwdrivers 9. When the carrier arrives at the working station, the support plate 27 is in a forward-moving state. Then, the stop drive cylinder 20 at the bottom of the carrier pressure plate 26 operates. Driven by the stop drive cylinder 20, the stop plate 21 moves upward to stop and limit the carrier. Then, driven by the carrier lifting cylinder 18, the carrier lifting plate 19 moves upward to lift the carrier and press it against the bottom of the carrier pressure plate 26. Then, driven by the second support block drive cylinder 30, the second carrier support blocks 31 on both sides extend to support and limit the ends of the carrier. After completion, the carrier lifting plate... 19 and stop plate 21 move down and reset. Then, under the drive of the pallet lateral movement drive cylinder 28, the support plate 27 moves backward to the bottom of the carrier. Then, the support plate 27 is driven to move up by the pallet lifting drive cylinder 29 to lift and press the lower part of the carrier. After the screw feeder 36 picks up the material, the intelligent electric screwdriver 9, driven by the servo module, cooperates with the visual scanning of the CCD camera 10 to upload the code to the MES positioning carrier and automatically tightens the screws in a specific order to complete the tightening process. Similarly, the intelligent electric screwdriver 9 on the other side completes the tightening process of the screws on the upper part of another set of carriers. After the left and right stations complete the tightening process, the lifting and positioning components are reset. The carrier is conveyed by the streamline conveyor seat 17 and flows out by itself. The screw disassembly operation is the same as above, and the processing process is completed.

[0045] In summary, this screw-making machine adopts an automated working method. Through the cooperation of the electric screwdriver mechanism and the material conveying mechanism, it can realize the automatic supply, conveying, positioning, screw-on / screw-off processing, and material discharge. The entire operation is automated without human intervention, exhibiting a high degree of automation. It can be perfectly integrated with the production line, which is conducive to the expansion of enterprise production scale and the improvement of production efficiency. It adopts a dual-head station setting, with two sets of intelligent electric screwdrivers 9 installed on the upper part of the gantry support 4. The intelligent electric screwdrivers 9 use vision positioning for precise and fast positioning, and with an independent servo drive structure, they can simultaneously complete the screw-on / screw-off processing on the upper part of the two carriers. This design effectively improves the processing efficiency of the equipment. It adopts a buffered feeding mechanism, in which the streamlined conveyor seat 17 supplies and transports the carrier material. During operation, the material can be placed offline by blocking, lifting, and supporting the carrier material at the buffer station. The lifted material is stored on the upper layer of the buffer station and will not affect the material supply below. Through material buffering, the problems of blockage and unstable supply demand in the material supply can be effectively solved, improving the stability and reliability of the supply. Combined with the rapid processing capability of the dual-head, it can achieve stable material supply and efficient processing.
