Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a back-to-back automatic screw fastening machine. Background Technology

[0002] Back-to-back automatic screw fastening machines are automated devices that integrate screw feeding, fastening, control, and worktable functions. They have two opposing work areas, allowing for simultaneous or alternating screw fastening. There are numerous reasons to use them. In terms of production efficiency, the dual-station design and rapid fastening speed significantly shorten cycle times and increase output. Regarding product quality, high-precision fastening and stable torque control ensure quality. From a labor cost perspective, automated operation replaces manual labor, reducing personnel training costs and significantly improving enterprise production efficiency.

[0003] When faced with product processing tasks requiring the assembly of multiple parts, traditional back-to-back automatic screw fastening machines have significant drawbacks. After each type of screw fastening operation is completed, the machine must return to its original position, and then rely on manual labor to perform a new round of parts assembly before a second fastening operation can be carried out. This process not only significantly lengthens the overall production time, resulting in a substantial reduction in production efficiency, but also puts production workers in a high-intensity working state for extended periods, greatly increasing their fatigue. Therefore, the back-to-back automatic screw fastening machine is proposed to solve the above problems. Utility Model Content

[0025] Reference Figure 1 , Figure 2 and Figure 3 An oil-water separator 5 is fixedly connected to one side of the electrical cabinet 1 to separate oil and water. An adsorption feeder 28 is installed on one side of the lower surface of the support frame 4 to feed the fixture above the Y-axis slide rail 10. An adsorption feeder 29 is installed on the other side of the lower surface of the support frame 4 to feed the fixture above the Y-axis slide rail 11. The touch screen 2 and the control button 3 are electrically connected and are used to control the operation of the components. A linear guide 14 is installed between the Z-axis slide rail 8 and the lowering cylinder 12 to limit the movement of the electric screwdriver locking assembly.

[0026] Specifically, an oil-water separator 5 is fixedly connected to one side of the electrical cabinet 1. The oil-water separator 5 separates the oil and water mixture in the system, ensuring that the pneumatic and hydraulic systems inside the equipment receive clean gas and liquid, thereby improving the stability of the equipment and extending its service life. The use of the oil-water separator 5 effectively prevents moisture and oil stains from corroding or clogging mechanical parts, ensuring the normal operation of the system. An adsorption feeder 28 is installed on one side of the lower surface of the support frame 4. The adsorption feeder 28 automatically adsorbs screws or other components and feeds them to the fixture above the Y-axis slide rail 10 through adsorption. This feeder ensures automated conveying of screws or components during production, reducing manual operation and improving production efficiency. An adsorption feeder 29 is installed on the other side of the lower surface of the support frame 4. Similar to the adsorption feeder 28, the adsorption feeder 29 is specifically used to feed the fixture above the Y-axis slide rail 11. To ensure synchronized operation of the material supply systems on both sides and avoid production bottlenecks caused by uneven material supply, the touch screen 2 and control button 3 are electrically connected. The touch screen 2 interacts with the operator through its intuitive display interface, allowing the operator to view the equipment status in real time, adjust working parameters, and monitor the production process. The touch screen 2 and control button 3 work together to provide comprehensive operation control functions. The control button 3 is used to start, stop, and perform other emergency operations on the equipment, ensuring that the operator can respond quickly and make corresponding adjustments when needed. A linear guide rail 14 is installed between the Z-axis slide rail 8 and the lowering cylinder 12. The linear guide rail 14 precisely limits the movement of the electric screwdriver locking assembly, ensuring that its movement trajectory in the Z-axis direction is accurate. By reducing friction and improving precision, the linear guide rail 14 ensures the stability and accuracy of the electric screwdriver locking assembly when performing screw locking operations, preventing operational errors or quality problems caused by unstable movement.

[0027] Working principle: When the machine is needed, the product 22 is first placed manually into the fixture above the Y-axis slide rail 10 and Y-axis slide rail 21. Then, the pressing cylinder 23 is activated, driving the pressing block 24 to press the product 22. Next, the positioning cylinder 25 is activated, extending the shaft column to position the fixture. This, combined with the activation of the X-axis slide rail 6, Y-axis slide rail 10, and Z-axis slide rail 8, causes the sleeve suction nozzle 19 to pick up the screw from the suction feeder 28, thus achieving the locking effect on the threaded hole on the front of the product 22. After locking the front, the product fixture is moved to the rear end via the Y-axis slide rail 10. Then, the positioning cylinder 25 retracts the shaft column, and simultaneously, the rotating cylinder 26 rotates the product fixture 90 degrees, adjusting the angle of the product 22. Finally, the positioning cylinder 25 extends the shaft column to position the fixture, and then... Through the coordination of X-axis slide rail 27, Y-axis slide rail 10, and Z-axis slide rail 29, the linkage sleeve suction nozzle 19 picks up screws from inside the suction feeder 29, thereby achieving the effect of fastening the threaded holes on the side of product 22. At this time, the positioning cylinder 25 retracts the shaft column, and the rotating cylinder 26 rotates the product fixture back to the origin, thus achieving the effect of returning Y-axis slide rail 10 to the loading position after fastening is completed. Then, by opening the lowering cylinder 23, the manual product 22 is removed and a new product 22 is placed. At the same time, when Y-axis slide rail 10 is loading and unloading, the equipment repeats the above actions to fasten the screws on the products on Y-axis slide rail 21; when Y-axis slide rail 21 is loading and unloading, the equipment fastens the screws on the products on Y-axis slide rail 10. Y-axis slide rail 10 and Y-axis slide rail 211 alternately load and unload, performing uninterrupted screw fastening work.
