Description

Technical Field

[0001] This utility model relates to the field of screw fastening machine technology, and in particular to a screw fastening machine with defective product recycling function. Background Technology

[0002] Screw fastening machines are widely used in product assembly requiring precise torque and fastening details. They are primarily used to automatically handle screw loading, unloading, and tightening operations. A screw fastening machine typically consists of a feeding section and an electric screwdriver section. The feeding section is responsible for screening and supplying screws, while the electric screwdriver section is responsible for tightening them. Existing screw fastening machines usually collect defective products by directly piling them into a recycling bin. However, as the number of defective products increases, their sharp edges can rub against and scratch the surfaces of other defective products already in the recycling bin. This can easily cause defective products to become unqualified, increasing the defect rate and production costs. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 2As shown, the present invention discloses a screw fastening machine with a defective product recycling function, characterized in that: it includes a screw fastening device, a feeding device and a discharging device used in conjunction with the screw fastening device, and a defective product recycling device disposed between the feeding device and the discharging device. The feeding device, the discharging device, and the defective product recycling device are arranged around the circumference of the screw fastening device, and the discharging device moves back and forth between the screw fastening device and the defective product recycling device.

[0023] During operation, the feeding and discharging devices are positioned front and back, the defective product recovery device is placed on the right side, and the screw fastening device is located in the middle. This arrangement ensures the feeding, discharging, and defective product recovery devices are positioned around the screw fastening device in the front, back, and right directions, resulting in a compact structure and high degree of coordination between the devices. The feeding device inputs the workpieces to be screwed into the screw fastening device for automated screw fastening. After fastening, the workpieces undergo visual inspection for defects. After comprehensive analysis of the inspection data, each fastened workpiece is effectively classified as either good or defective. The discharging device then rotates forward to move good workpieces to the next station for unified storage. The discharging device rotates backward to move defective workpieces to the defective product recovery device for recycling. An external robotic arm then picks up the defective workpieces from the recovery device and transfers them to an external storage rack, where multiple defective workpieces are spaced apart. The screw fastening device is a conventional screw fastening machine; its specific shape, structure, and working principle will not be detailed here. This utility model has a compact and reasonable structure, high degree of cooperation, facilitates the automatic transfer and recycling of defective products, has a good recycling effect, and reduces production costs.

[0024] In this embodiment, the feeding device 2 and the discharging device 3 have the same structure. The feeding device 2 includes a transfer platform 21, a linear module 22 driven and connected to the transfer platform 21, a conveyor belt 23 disposed on both sides of the transfer platform 21, a transmission wheel 24 rotatably disposed on the transfer platform 21, and a first drive motor 25 disposed on the outside of the transfer platform 21. The output end of the first drive motor 25 is driven and connected to a drive wheel 26. The drive wheel 26 is driven and connected to the transmission wheel 24 through the conveyor belt 23. A first material sensor 27 is disposed on the side of the transfer platform 21 near the conveyor belt 23. Specifically, preferably, there are two screw fastening devices 1. The feeding device 2 and the discharging device 3 have the same structure. The linear module 22 drives the transfer table 21 to move back and forth between the two screw fastening devices 1. The first drive motor 25 drives the drive wheel 26 to rotate. The rotating drive wheel 26 is connected to the transmission wheel 24 through the conveyor belt 23. The workpiece to be fastened is transported to the screw fastening device 1 by the circulating conveyor belt 23, realizing the rapid feeding of the two screw fastening devices 1 with high feeding efficiency. The first material sensor 27 is used to sense and detect the presence of the workpiece to be fastened and feed it back to the control system. The control system further controls the forward rotation, reverse rotation or pause of the first drive motor 25, resulting in a high degree of intelligent control.

[0025] The transfer platform 21 of this embodiment includes two spaced-apart supports 211 and an adjusting rod 212 disposed between the two supports 211. Each support 211 has a clamping groove 213 and an adjusting groove 214 communicating with the clamping groove 213. The adjusting rod 212 is accommodated within the clamping groove 213, allowing the adjusting groove 214 to adjust the clamping tightness of the clamping groove 213 on the adjusting rod 212. Specifically, the two supports 211 are spaced apart and parallel, and the adjusting rod 212 is horizontally disposed between the two supports 211. When the adjusting rod 212 is inserted into the clamping groove 213, an external screw passes through and locks the clamping groove 213, thereby adjusting the clamping tightness of the adjusting rod 212. Furthermore, the distance between the two supports 211 can be adjusted according to the specifications and dimensions of the workpiece to be screwed, resulting in good adjustment effect and high operational compatibility.

The output end of the second drive motor is connected to a drive wheel, which is driven by the conveyor belt. A second material sensor is located on the side of the frame near the conveyor belt. Specifically, the second drive motor drives the drive wheel to rotate, and the rotating drive wheel is driven by the conveyor belt. The circulating conveyor belt transports defective products, facilitating the use of an external robotic arm to pick up defective products from the recycling device and transfer them to an external storage rack. The storage rack then stores multiple defective products in an orderly manner.

[0027] The above description is only a preferred embodiment of this utility model.
