Description

Technical Field

[0001] This utility model relates to the field of screw processing, and in particular to a screw blowing and suction combined feeding and locking mechanism. Background Technology

[0002] Screw feeders are common components of automatic screw machines, playing a crucial role in the automatic tightening process. They efficiently, quickly, and reliably deliver screws to designated positions to meet production demands. Screw feeders come in various types, such as vibratory feeders, linear vibratory feeders, and screw feeders.

[0003] Screw feeding requires a locking mechanism. Existing locking mechanisms are generally of two types: suction locking (good stability, but slow efficiency) and air-blowing locking (fast efficiency, but unable to lock deep holes). If the product has deep holes or is thick, previous technologies are inefficient and cannot achieve stability.

[0004] To address this issue, a screw-blowing and suction combined feeding and locking mechanism is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a screw blowing and suction combined feeding and locking mechanism, which aims to improve the existing technology. The existing mechanisms are generally suction locking (good stability, slow efficiency) and air blowing locking (fast efficiency, but unable to lock deep holes). When encountering deep holes or large products, the previous technology is inefficient and cannot achieve stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A screw blowing and suction combined feeding and locking mechanism includes: a blow-type screw feeder, a sliding table provided on the front of the blow-type screw feeder, an electric screwdriver fixedly installed on the front of the sliding table, a suction nozzle fixedly connected to the bottom of the electric screwdriver, a dispensing cylinder fixedly installed at the bottom of the front of the sliding table, and a horizontal plate fixedly connected to the output end of the dispensing cylinder.

[0008] Through the above technical solution, the mechanism adopts an air-blowing screw feeder, combined with an electric screwdriver and a suction nozzle on the sliding table, to achieve rapid and accurate screw feeding and fastening. The air-blowing feeder ensures that the screw is stably and continuously delivered to the designated position, improving the reliability of the feeding. The design of the suction nozzle allows the screw to be firmly attracted during the fastening process, avoiding the problem of screw falling or positional deviation. At the same time, the presence of the sliding table allows the electric screwdriver to be flexibly adjusted to adapt to the fastening requirements of different workpieces. This air-blowing and suction combination not only improves the efficiency of screw fastening but also greatly enhances the accuracy and stability of fastening. In addition, the mechanism has a compact structure, is easy to operate, and is easy to maintain and repair, reducing production costs and manual intervention.

[0009] As a further description of the above technical solution: a special-shaped plate is fixedly connected to the left side of the sliding table, and a screw guide tube is fixedly connected to the top of the special-shaped plate.

[0010] Through the above technical solution, a special-shaped plate is cleverly fixedly connected to the left side of the sliding table. This design not only enhances the structural stability of the mechanism, but also provides strong support for the precise guidance of the screw. A screw guide tube is fixedly connected to the top of the special-shaped plate. This guide tube serves as a transition channel for the screw from the feeder to the fastening position, ensuring the smoothness and accuracy of the screw during the transmission process. The design of the screw guide tube takes into account the size and shape of the screw, which can effectively prevent the screw from jamming or deviating during the transmission process, thereby improving the efficiency and accuracy of screw fastening.

[0011] As a further description of the above technical solution: both sides of the top of the horizontal plate are fixedly connected to beam detectors.

[0012] Through the above technical solution, two through-beam detectors are fixedly connected to both sides of the top of the horizontal plate. This design cleverly utilizes optical principles. By emitting and receiving light through the through-beam detectors, the presence of screws above the horizontal plate can be monitored in real time. When the screws are correctly delivered to the top of the horizontal plate, the through-beam detectors can quickly sense and send a signal to ensure that the subsequent electric screwdriver operation can be carried out on time and accurately. This feature greatly improves the automation level of screw fastening and avoids fastening failure caused by screws not being in place or misaligned, thereby ensuring the continuity and stability of the production line.

[0013] As a further description of the above technical solution: the bottom of the screw guide tube is provided with a screw outlet.

[0014] Through the above technical solution, the screw guide tube serves as the channel for screw transmission. The screw outlet at its bottom ensures that the screw can be accurately delivered to the working position according to the predetermined path and sequence. The size and shape of the screw outlet are usually customized according to the specifications and type of the screw to ensure that the screw can pass through smoothly without jamming or falling off. At the same time, the position of the outlet is also matched with the position of the electric screwdriver or locking head, so that the screw can be immediately grabbed by the locking head and locked after being delivered.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a blow-type screw feeder is used to supply screws, and an electric screwdriver on a sliding table performs the fastening operation. When a screw needs to be fastened, the sliding table moves the electric screwdriver to the appropriate position. The suction nozzle at the bottom of the electric screwdriver, under the action of the dispensing cylinder, picks up the screw through the screw outlet at the bottom of the screw guide tube. At the same time, the through-beam detector at the top of the horizontal plate ensures the accurate position and presence of the screw, avoiding empty suction or mis-suction. Once the suction nozzle successfully picks up the screw, the sliding table moves again, bringing the electric screwdriver and screw to the fastening position. At this time, the electric screwdriver starts and fastens the screw to the designated position. Throughout the process, the screw guide tube ensures the smooth flow of the screw, the screw outlet precisely controls the screw discharge, and the through-beam detector provides necessary feedback and detection, ensuring the accuracy and efficiency of the fastening process. This mechanism realizes automated screw feeding and fastening, greatly improving production efficiency and quality.

[0017] 2. In this utility model, the guide tube serves as a transition channel for the screw from the feeder to the fastening position, ensuring the smooth and accurate transmission of the screw. The design of the screw guide tube takes into account the size and shape of the screw, effectively preventing the screw from jamming or shifting during transmission, thereby improving the efficiency and accuracy of screw fastening.

In addition, the mechanism has a compact structure, is easy to operate, and is easy to maintain and repair, reducing production costs and manual intervention.

[0024] Reference Figure 1-2 A shaped plate 7 is fixedly connected to the left side of the sliding table 2, and a screw guide tube 8 is fixedly connected to the top of the shaped plate 7. The shaped plate 7 is cleverly fixedly connected to the left side of the sliding table 2. This design not only enhances the structural stability of the mechanism, but also provides strong support for the precise guidance of the screw. The screw guide tube 8 is fixedly connected to the top of the shaped plate 7. This guide tube serves as a transition channel for the screw from the feeder to the fastening position, ensuring the smoothness and accuracy of the screw during the transmission process. The design of the screw guide tube 8 takes into account the size and shape of the screw, which can effectively prevent the screw from jamming or deviating during the transmission process, thereby improving the efficiency and accuracy of screw fastening.

[0025] Reference Figure 1-2Both sides of the top of the horizontal plate 6 are fixedly connected to through-beam detectors 9. This design cleverly utilizes optical principles. By emitting and receiving light through the through-beam detectors 9, the presence of screws above the horizontal plate 6 is monitored in real time. When a screw is correctly delivered above the horizontal plate 6, the through-beam detectors 9 can quickly sense it and send a signal, ensuring that the subsequent operation of the electric screwdriver 3 can be carried out on time and accurately. This feature greatly improves the automation level of screw fastening and avoids fastening failure caused by screws not being in place or misaligned. This ensures the continuity and stability of the production line. The bottom of the screw guide tube 8 is provided with a screw outlet 10. The screw guide tube 8 serves as a channel for screw transmission, and the screw outlet 10 at its bottom ensures that the screw can be accurately delivered to the working position according to the predetermined path and sequence.

At the same time, the position of the outlet is also matched with the position of the electric screwdriver 3 or the locking head, so that the screw can be immediately grabbed by the locking head and locked after being delivered.

[0026] Working Principle: The air-blowing screw feeder 1 provides screws, which are then fastened via an electric screwdriver 3 on the sliding table 2. When a screw needs to be fastened, the sliding table 2 moves the electric screwdriver 3 to the appropriate position. The suction nozzle 4 at the bottom of the electric screwdriver 3, under the action of the dispensing cylinder 5, picks up the screw through the screw outlet 10 at the bottom of the screw guide tube 8. At the same time, the through-beam detector 9 at the top of the horizontal plate 6 ensures the accurate position and presence of the screw, avoiding empty suction or mis-suction. Once the suction nozzle 4 successfully picks up the screw, the sliding table 2 moves again, bringing the electric screwdriver 3 and the screw to the fastening position. At this time, the electric screwdriver 3 starts and fastens the screw to the designated position. Throughout the process, the screw guide tube 8 ensures the smooth flow of the screw, the screw outlet 10 precisely controls the screw discharge, and the through-beam detector 9 provides necessary feedback and detection, ensuring the accuracy and efficiency of the fastening process. This mechanism realizes automated screw feeding and fastening, greatly improving production efficiency and quality.
