[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. With the development of technology, welding robots have been widely used to improve production efficiency.

[0003] At present, during the welding process, workers are still required to manually load the materials, clamp and position them, and then the welding robot will automatically weld according to the set processing procedures. In addition, most of the production workshops are single-station operations. After the workers complete the clamping of the materials, they need to wait for the welding robot to complete welding, then remove the finished product, and complete the clamping of new materials. During the loading process of the workers, the welding robot is in a stagnant state, and the overall work efficiency is low. Summary of the invention

[0050] The implementation principle of a double-station high-efficiency welding equipment in an embodiment of the present application is as follows: the staff places the workpiece on any clamping assembly 51 and completes the clamping, slides the sliding door 3 to that side, and the sliding door 3 slides, driving the first gear 621 and the first rack 622 to slide, and the first gear 621 rotates, driving the screw rod 623 to rotate, and the screw rod 623 and the protective cover 61 are threadedly connected. The screw rod 623 is a reciprocating screw rod 623. During the sliding process of the sliding door 3, the protective cover 61 first rises and then falls, so as to avoid the clamping assembly 51 during the movement, and after the movement stops, the lower end of the protective cover 61 is attached to the upper surface of the workbench 4.

[0051] During the sliding process, the second gear 632 meshes with the second rack 64, and the second gear 632 rotates, driving the protective plate 631 to rotate, so that the protective plate 631 that was originally parallel to the sliding door 3 rotates in a direction away from the sliding door 3, so that the protective plate 631 is perpendicular to the sliding door 3, and the protective plate 631 that was originally perpendicular to the sliding door 3 rotates in a direction away from the other protective plate 631, so that the protective plate 631 is parallel to the sliding door 3.

[0052] The staff places the workpiece on another clamping assembly 51 and completes the clamping. The welding robot 2 extends from the opening 611 to weld the workpiece. The welding robot 2 blocks the infrared rays emitted by the infrared grating 71. The infrared grating 71 sends a signal to the processor. The processor processes the signal and sends the signal to the drive cylinder 73. The piston rod of the drive cylinder 73 extends, pushes the fixed block 72 to be embedded in the fixed groove 13, pushes the slider 74 to overcome the elastic force of the reset member 75 and be embedded in the slide groove 14. The upper end of the slider 74 abuts against the contact switch 76, so that the contact switch 76 is closed. The indicator light 77 lights up, and the fan 812 works to discharge the gas in the working chamber 11 through the exhaust pipe 811.

[0053] After the welding robot 2 finishes welding, the welding robot 2 detaches from the protective cover 61, and the infrared rays emitted by the infrared grating 71 are blocked. The infrared grating 71 sends a signal to the processor, and the processor processes the signal and sends the signal to the drive cylinder 73. The piston rod of the drive cylinder 73 contracts, driving the fixed block 72 to detach from the fixed groove 13. The slider 74 moves away from the contact switch 76 under the action of the elastic force of the reset member 75, and the contact switch 76 is disconnected, the indicator light 77 goes out, the fan 812 stops running, and the staff moves the sliding door 3, removes the welded workpiece, and clamps the next workpiece.

[0054] The present application also discloses an application method of a dual-station high-efficiency welding device, comprising the following steps: S1: Place the workpiece on any clamping assembly 51 to complete the clamping. S2: Move the sliding door 3 to one side of the clamping assembly 51 that has completed the clamping, and place the workpiece on another clamping assembly 51 to complete the clamping. The welding robot 2 extends into the protective cover 61 to weld the workpiece. The infrared grating 71 detects the welding robot 2 and transmits the signal to the processor. The processor controls the piston rod of the drive cylinder 73 to extend, driving the fixing block 72 to embed into the fixing groove 13, so as to achieve the relative fixation of the sliding door 3 and the welding room 1; the fixing block 72 abuts against the slider 74, the slider 74 abuts against the contact switch 76, the contact switch 76 is closed, the indicator light 77 is on, and the fan 812 is running.

[0055] S3: When the indicator light 77 goes out, move the sliding door 3 to the side of the clamping assembly 51 that has completed the clamping, remove the welded workpiece, and repeat steps S1-S2.

[0056] The implementation principle of the application method of a dual-station high-efficiency welding device in the embodiment of the present application is: to enable the welding robot 2 to weld and the staff to clamp at the same time, thereby improving work efficiency.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
