[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 In this embodiment of the utility model, the wire box nut assembly machine includes a frame 2. A wire box infeed conveyor mechanism 1 is provided on one side of the top of the frame 2 to transport wire boxes. A nut assembly mechanism 3 is provided on one side of the wire box infeed conveyor mechanism 1 to assemble nuts onto the wire boxes it is transporting. The nut assembly mechanism 3 is mounted on the frame 2. A wire box discharge mechanism 5 is provided on one side of the nut assembly mechanism 3 to transport wire boxes with nuts assembled on them. The wire box discharge mechanism 5 is mounted on the frame 2. A control computer 4 is provided on the outside of the frame 2 to electrically connect and control the wire box infeed conveyor mechanism 1, the nut assembly mechanism 3, and the wire box discharge mechanism 5. When the wire box infeed conveyor mechanism 1 transports wire boxes sequentially to the nut assembly mechanism 3, the nut assembly mechanism 3 assembles nuts onto the wire boxes transported below. The wire boxes with nuts are then pushed to the wire box discharge mechanism 5, which transports the wire boxes with nuts assembled on them so that other components can be installed on the wire boxes subsequently.

[0022] The box-in conveying mechanism 1 includes a conveyor line 6 mounted on a frame 2. A box-in-position sensor 9 is located at the front end of the conveyor line 6 to detect the position of the box. A box-in-direction sensor 10 is located on one side of the box-in-position sensor 9 to detect the direction of the box. Anti-jump plates 11, which limit the pushing of the box and are mounted horizontally on the conveyor line 6, are distributed on the left and right sides of the front end of the conveyor line 6. A box-in-position cylinder 8 pushes the box after it has been detected by the box-in-direction sensor 10 and is in the correct direction. The box-in-position cylinder pushes the box to the nut assembly mechanism 3. The conveyor line 6 also includes a motor 7 for transporting the box on the frame 2. The position sensor 9 is electrically connected to the motor 7. When the wire box is driven by the motor 7 to the front end of the conveyor line 6, the position sensor 9 senses the wire box and drives the motor 7 to stop, causing the conveyor line 6 to stop. At this time, the wire box orientation sensor 10 detects the placement direction of the wire box located on one side of the wire box position sensor 9. The wire box with the correct orientation is pushed to the nut assembly mechanism 3 by the box inlet cylinder 8. If the orientation is incorrect, the equipment will alarm to prevent the nut assembly mechanism 3 from damaging the wire box when assembling the nut. In addition, the anti-jump plate 11 can prevent the wire box from jumping during the pushing process, reducing the failure rate of the equipment.

[0023] The nut assembly mechanism 3 includes a wire box placement platform (not shown in the figure) on one side of the wire box conveyor mechanism 1, which pushes the wire box thereon for placement. The wire box placement platform is mounted on the frame 2. A nut vibratory feeder 14 is provided on one side of the wire box placement platform to vibrate and convey the nut to the area below the wire box placement platform. A nut lifting cylinder 12 is provided below the wire box placement platform to lift the nut into the wire box placed above it. A nut track 13 is provided between the wire box placement platform and the nut lifting cylinder 12. 13 is horizontally mounted below the wire box placement platform. The nut track 13 is interconnected with the wire box placement platform. The nut lifting cylinder 12 is located below the nut track 13. A pin 21 that can penetrate the nut track 13 is provided above the nut lifting cylinder 12. The nut vibrating and transported by the nut vibrating plate 14 can be slid through the nut track 13 to the position above the nut lifting cylinder 12. Then, the pin 21 is driven by the nut lifting cylinder 12 to penetrate the nut track 13 and lift the nut into the wire box placed above the wire box placement platform.

[0024] The bottom of the wire box placement platform is provided with an elastic clamping plate 19 for elastically clamping the wire box. The bottom of the wire box placement platform is formed with a through hole (not shown in the figure) for the nut to pass through and aligned with the mounting hole of the wire box. The top of the wire box placement platform is provided with a pressing cylinder 15 for limiting and pressing the wire box. When the wire box after testing is pushed onto the wire box placement platform, the wire box with the nut installed on it will hold the wire box to be nut installed, and make the wire box to be nut installed located on the side of the elastic clamping plate 19 and below the pressing cylinder 15. The clamping and limiting of the wire box by the elastic clamping plate 19 and the pressing cylinder 15 makes the mounting hole of the wire box aligned with the through hole. This allows the subsequent nut lifting cylinder 12 to drive the ejector pin 21 through the nut track 13 and lift the nut into the mounting hole of the wire box placed above the wire box placement platform.

[0025] A detection cylinder 16 is installed on one side of the top of the outer edge of the wire box placement platform. A detection sensor 17 for detecting the wire box is driven at the bottom of the detection cylinder 16. The detection sensor 17 is parallel to the bottom edge of the outer edge of the wire box placement platform. A positioning plate 18 for limiting and blocking the wire box is installed on one side of the bottom edge of the outer edge of the wire box placement platform. When a wire box with a nut installed is pushed to the positioning plate 18 by the next wire box to be fitted with a nut, the detection cylinder 16 drives the detection sensor 17 to move into the wire box. The detection sensor 17 can then detect the wire box. If the detection sensor 17 detects that nuts are installed at all four corners inside the wire box, the wire box is considered a qualified product. If the detection sensor 17 cannot detect a nut at any of the four corners inside the wire box, the wire box is considered a defective product. The equipment will stop and alarm, and the machine will wait for personnel to handle the situation.

[0026] A discharge cylinder 24 is provided on the other side of the bottom of the wire box placement platform. The discharge cylinder 24 drives a push plate 25 that can push the wire boxes that have been inspected. The push plate 25 is located at the front end of the positioning plate 18. Through the cooperation between the discharge cylinder 24 and the push plate 25, the wire boxes that have passed the inspection and are located at the positioning plate 18 can be pushed to the wire box discharge mechanism 5.

[0027] The wire box unloading mechanism 5 includes a finished product tray 23 located on the other side of the frame 2, which carries and transports qualified wire boxes. The finished product tray 23 is located on one side of the nut assembly mechanism 3, and a full-load sensor 22 is provided at the end of the finished product tray to detect the wire boxes. The qualified finished wire boxes are pushed onto the finished product tray 23 by the push plate 25 driven by the unloading cylinder 24, forming a row of finished products for employees to pick up and pack. When the full-load sensor 22 detects wire boxes, it means that the finished product tray 3 is full of wire boxes. To prevent the wire boxes from falling, the equipment will alarm and temporarily stop production until the employees take away the wire boxes.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
