[0021] 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.

[0022] like Figures 1 to 5 As shown, this embodiment proposes a novel glue application and screw fastening device, which includes a welding frame 1, a three-axis servo module 2, a rotary indexing plate 3, an electrical control cabinet 4, a three-axis glue dispensing machine 5, a barcode scanner 6, a weighing unit 9, and a vision inspection instrument 10, wherein the vision inspection instrument 10 is a Cognex camera.

[0023] The three-axis servo module 2 is fixedly installed on the rear inner wall of the welding frame 1. The rotary indexing plate 3 is located below the three-axis servo module 2 and is fixedly installed on the bottom inner wall of the welding frame 1. The electrical control cabinet 4 is fixedly installed on the rear side of the welding frame 1. The three-axis glue dispensing machine 5 is fixedly installed on the top rear side of the welding frame 1 and is located behind the rotary indexing plate 3. The barcode scanner 6 is fixedly installed inside the welding frame 1. The weighing unit 9 is fixedly installed on the top rear side of the welding frame 1. The vision inspection instrument 10 is fixedly installed on the top inner wall of the welding frame 1 and is located above the three-axis glue dispensing machine 5. An electric nut wrench 201 is fixedly installed at the bottom of the moving end of the three-axis servo module 2. A human-machine interface 11 is fixedly installed on the front side of the welding frame 1. A cycle start button is provided on the front side of the human-machine interface 11. The device includes a PLC controller electrically connected to the electrical control cabinet 4, a three-axis servo module 2, a rotary indexing plate 3, a three-axis dispensing machine 5, a barcode scanner 6, a weighing unit 9, and a vision inspection instrument 10, all of which are electrically connected to the PLC controller and the electrical control cabinet 4. There are multiple barcode scanners 6 arranged around the rotary indexing plate 3. The rotary indexing plate 3 is equipped with clamps. A fan 12, which is tilted forward and downward, is fixedly installed on the top front side of the welding frame 1 to assist in cooling personnel when the ambient temperature is high. A multi-color warning light 13, which is electrically connected to the PLC controller, is fixedly installed on the top of the welding frame 1 to provide warnings under the control of the PLC controller when a fault occurs. The bottom of the welding frame 1 is rectangular and has six lockable casters that are rotatably installed to facilitate the movement of the entire device by personnel.

[0024] The rear side of the welding frame 1 is equipped with a screw feeder 8 and an oil pump 7 for injecting oil into the screws;

[0025] The three-axis servo module 2, rotary indexing plate 3, three-axis glue dispensing machine 5, barcode scanner 6, and weighing unit 9 are all controlled by a PLC controller. The rotary indexing plate 3 is used to drive the motor product to rotate to other workstations after it is placed and fixed. The barcode scanner 6 is used to scan the product code on the outer surface of the frame housing product of the motor product and transmit it to the human-machine interface 11 for display and recording when the frame housing product of the motor product is placed. The three-axis servo module 2 is used to drive the electric nut wrench 201 to perform XYZ three-axis motion adjustment. The three-axis glue dispensing machine 5 is used to apply glue to the screw mounting holes of the motor product.

[0026] The usage method of this embodiment is as follows: During use, the worker first places a motor product in the rotating indexing plate 3 and manually operates the clamp to clamp and lock the motor product. Then, the worker presses the cycle start button on the human-machine interface 11. At this time, the barcode scanner 6 first scans the barcode on the outside of the motor product and transmits it to the human-machine interface 11 for display and recording. The PLC controller of the human-machine interface 11 controls the rotating indexing plate 3 to rotate the motor product to the workstation where the three-axis glue dispensing machine 5 is located. The three-axis glue dispensing machine 5, controlled by the PLC controller, applies glue to the multi-hole positions of the motor product. The vision inspection instrument 10 checks the glue application effect. After glue application is completed, the PLC controller controls the rotating indexing plate 3 to rotate the motor product to the tightening workstation where the electric nut wrench 201 is located. The worker pre-screws the required screws slightly into the corresponding holes on the frame housing product, and then places the frame housing product of the motor product on its corresponding outer side. The barcode scanner 6 scans the product code on the surface of the frame housing product and transmits it to the human-machine interface 11 for further processing. The system displays and records data. Then, the three-axis servo module 2, controlled by the PLC controller, drives the electric nut wrench 201 to move and adjust to the screw position. The electric nut wrench 201, controlled by the PLC controller, tightens the first screw. Then, the three-axis servo module 2, controlled by the PLC controller, drives the electric nut wrench 201 to move and adjust to the second screw position to tighten it. This process is repeated to achieve automatic tightening of multiple screws. After the tightening cycle is completed, the three-axis servo module 2, controlled by the PLC controller, drives the electric nut wrench 201 to return to its original position. The worker can then remove the motor product with the frame housing installed. By automatically applying glue to the holes on the motor product for screw installation and automatically tightening multiple screws after fitting the frame housing, the glue application and screw tightening stations can be integrated into one unit. This eliminates the need for separate operation of multiple devices, simplifying the back-and-forth clamping and moving operation process. Furthermore, by integrating the two stations into one unit, the overall size of the equipment is small and more flexible.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
