The assembly platform 100 is used to provide a mounting platform for the punching mechanism 200 and the welding mechanism 300, while improving the rationality of the layout of the punching mechanism 200 and the welding mechanism 300. The punching mechanism 200 is used to punch the bumper to be processed, and the welding mechanism 300 is used to weld the radar bracket at the punched holes.

[0026] The punching and welding equipment described in this embodiment integrates the punching mechanism 200 and the welding mechanism 300 on the assembly platform 100, thereby enabling it to be compatible with the punching process and the welding process. The above processes can be highly coordinated and high-precision processing of the same product can be achieved without additional assembly and transportation. This not only improves product quality and yield rate, but also significantly improves production line efficiency. Compared with conventional processing technologies at this stage, this application has significant advantages such as a wide range of applications, simple operation, high degree of integration, good controllability, high processing quality and efficiency, and provides new ideas for punching and welding processing.

[0027] It should be noted that, for ease of expression, this embodiment defines the length direction of the punching and welding equipment as the first direction X, the width direction of the equipment as the second direction Y, and the height direction of the equipment as the third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

[0028] See also Figures 1 to 3As shown, the assembly platform 100 in this embodiment includes a main body 110 and an extension portion 120, wherein the main body 110 is arranged in a horizontal direction, and the extension portion 120 is connected to one end of the main body 110 and extends along the third direction Z. Based on this, the main body 110 and the extension portion 120 together form an "L"-shaped element. Furthermore, the main body 110 is used to assemble the punching knife 230, the punching seat 270 and the welding mechanism 300, and the extension portion 120 is used to assemble the punching mechanism 200, thereby avoiding the problem of mutual interference between the individual structures.

[0029] In this embodiment, the assembly platform 100 is provided with a first sliding module 130 and a first slide 140. The first sliding module 130 extends along a first direction X. The first slide 140 is slidably connected to the first sliding module 130, and the punching blade 230 is connected to the first slide 140. Furthermore, the first sliding module 130 is connected to the main body 110 and is disposed near the extension portion 120. The first slide 140 has a slide groove at the bottom, which enables it to slide along the first module. A frame for assembling the punching blade 230 is mounted on the first slide 140, which is used to connect the punching driver 210 and the punching blade 230. As a result, the extension height of the frame is no less than the extension height of the extension portion 120. Based on the above structural arrangement, the punching blade 230 can stably move along the first direction X under the action of the punching driver 210.

[0030] Furthermore, the assembly platform 100 is further provided with a second sliding module 150 and a second slide 160. The second sliding module 150 extends along the first direction X and is spaced apart from and co-aligned with the first sliding module 130. The second slide 160 is slidably connected to the second sliding module 150, and the punch seat 270 is connected to the second slide 160. The second sliding module 150 is connected to the main body 110 and is disposed away from the extension portion 120.

In this embodiment, the third sliding module 170 and the third slide 180 are used to realize the movement of the welding gun 330. In order to reduce the overall space occupied by the equipment, the third sliding module 170 is set on the second slide 160. The welding gun 330 and the punch seat 270 are set on the same side and can move relative to each other. Based on the above structure, the welding gun 330 can not only realize coarse position adjustment in the first direction X through the second slide 160, but also realize fine position adjustment through the third slide 180 during welding processing, thereby further improving its flexibility of use and welding processing accuracy.

The positioning member is inserted into / disengaged from the positioning holes by the positioning driver 261. During the actual processing, the operator determines the position of the component to be processed and the position of the punch seat 270 through the pre-pressing assembly 240, and then fixes the position of the punch seat 270 through the positioning assembly 260, thereby improving the quality and accuracy of the punching.

[0033] Specifically, the punching mechanism 200 in this embodiment further includes a punching driver 210, a first transmission rod 220, and a punch seat driver 280. The punching driver 210 is fixedly connected to one end of the assembly platform 100, and the two ends of the first transmission rod 220 are respectively connected to the working end of the punching driver 210 and the punching knife 230; the punch seat driver 280 is fixedly connected to the other end of the assembly platform 100, and the punch seat 270 is connected to the working end of the punch seat driver 280.

Furthermore, the welding mechanism 300 in this embodiment also includes a transducer 340 and a cooling assembly 350. The transducer 340 is connected to the welding gun 330 and is disposed around the welding gun 330. The transducer 340 converts electrical energy into high-frequency mechanical vibrations, enabling the welding head to apply pressure to the workpiece and perform vibration welding, thereby ensuring efficient and stable energy transfer during the welding process. The cooling assembly 350 is used to cool the heat generated by the transducer 340 and the welding gun 330 during the welding process, thereby improving welding accuracy and extending the service life of the welding mechanism 300.

[0035] This embodiment also includes a control system and an adjustment unit 250. The adjustment unit 250 is connected to the punching driver 210. The adjustment unit 250, the punching mechanism 200, and the welding mechanism 300 are respectively connected to the control system. During actual production and processing, the operator can use the control system to adjust the above structures in real time, thereby increasing the flexibility of the device. The operator can also use the control system to preset parameters, thereby increasing the automation level of the device.

[0036] In summary, the punching and welding equipment described in the present invention integrates the punching mechanism 200 and the welding mechanism 300 on the assembly platform 100, thereby enabling it to be compatible with the punching process and the welding process. The above processes can be highly coordinated and can achieve high-precision processing of the same product without additional assembly and transportation, which not only improves product quality and yield rate, but also significantly improves production line efficiency.
