[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 and Figure 2 As shown, the automatic screw fastening machine for short connectors includes a short connector feeding device 1, a screw feeding device 2, a waiting track 3, a conveying track 4, a screw tightening device 5, a short connector positioning cylinder 6, and a base box 7. All components are installed on the base box 7 and work in coordination through an electrical control system.

[0021] The short connector feeding device 1 adopts a vibratory feeder structure. The vibratory feeder is equipped with a spiral track and an orientation mechanism, such as a baffle based on the shape of the short connector, which is used to orient the short connector in an upward orientation. The discharge port of the short connector feeding device 1 is connected to the waiting track 3 through a guide groove. The short connectors enter the waiting track 3 in sequence under the action of vibration. The waiting track 3 is a straight track with a buffer spring inside, which is used to temporarily store the short connectors and prevent them from accumulating.

[0022] The end of the waiting track 3 is connected to the conveying track 4. The conveying track 4 adopts a belt conveying mechanism driven by a stepper motor to gradually convey the short connector to the screw tightening station. The end of the conveying track 4 is equipped with a short connector positioning cylinder 6. The short connector positioning cylinder 6 is a double-acting cylinder with a V-block installed at the front end of its piston rod. It is used to accurately position and correct the short connector before tightening the screw, so as to ensure that the threaded hole of the short connector is aligned with the screw tightening device 5.

[0023] The screw feeding device 2 also adopts a vibratory feeder structure. The vibratory feeder is equipped with a sorting track and a posture adjustment mechanism to arrange the screws in an orderly manner with the large end facing up and the thread facing down and transport them to the waiting position below the screw tightening device 5. A photoelectric sensor is provided at the end of the conveying device to detect whether the screws are in place.

[0024] The screw tightening device 5 includes a cylinder 51 and an electric screwdriver 52. The cylinder 51 drives the electric screwdriver 52 to move up and down through a vertical slider mechanism. The cylinder 51 is used to press the screw vertically into the threaded hole of the shorting piece. The electric screwdriver 52 is used to tighten the screw. The electric screwdriver 52 has a torque detection function and integrates a torque sensor. It automatically stops when the tightening torque reaches the preset value to ensure that the screw tightening torque is consistent.

[0025] The base box 7 is used to support and accommodate the above-mentioned devices. The side of the base box 7 is provided with a discharge port 71 for outputting the assembled short connector. Below the discharge port 71 is an extension bracket 72. A qualified product collection frame 73 is fixedly installed on the top of the extension bracket 72. The qualified product collection frame 73 is fixed by a buckle and is used to collect the assembled parts.

[0026] The electrical control system uses a PLC, which works in conjunction with various position sensors, photoelectric sensors, and other sensors to control the automated operation of the entire workflow.

[0027] The working principle of this automatic screw-driving machine for shorting connectors will be explained in detail below.

[0028] like Figure 1 , Figure 2 As shown, the short connector feeding device 1 uses vibration to orient the short connectors in an upward-facing position to the waiting track 3. After being temporarily stored in the waiting track 3, the short connectors are pushed one by one to the conveying track 4. The conveying track 4 gradually conveys the short connectors to the screw tightening station. When the short connector reaches the end of the conveying track 4, the position sensor triggers the short connector positioning cylinder 6 to accurately position and correct the short connector. At the same time, the screw feeding device 2 conveys the screw to the waiting position below the screw tightening device 5. The cylinder 51 of the screw tightening device 5 moves downward to press the screw into the threaded hole of the short connector. Then, the electric screwdriver 52 starts to tighten the screw. The torque detection function ensures that the screw tightening torque meets the preset value. The assembled short connector is output through the discharge port 71 of the base box 7 and falls into the qualified product collection box 73 for collection by means of the inclined guide plate. The whole work process is automated and requires no manual intervention.
