[0075] Working principle and process:

[0076] When this solution is in use, a manual position can be set between each device to load each material onto the tray 3, or to load each component of the coil assembly onto the tray 3, and then mark and scan the product at the marking and scanning location. The product that fails the scanning is unloaded by the unqualified product unloading component 1, and then the tray 3 is transported to the coil winding machine through the material transport component, and the wire rack 105 is placed into the coil winding machine manually or by a robot for winding, and after winding, it is taken out manually or by a robot and placed back on the corresponding tooling on the tray 3.

[0077] Afterwards, the material transport component drives the tray 3 to the coil welding detection equipment, the loading component controls the first clamping component 14 to be placed between the two detection cameras 16, and the horizontal rotation component 78 drives the first clamping component 14 to control the wire rack 105 to rotate in the vertical direction to realize the detection of the two detection cameras. Subsequently, the loading component places the wire rack 105 on the workpiece positioning tool on the rotating disk, and the rotating disk rotates to transport the wire rack 105 to the clamping component 25 for clamping. Then, the first welding component performs welding between the winding and the wire rack 105 terminal. Then, the rotating disk drives the workpiece positioning tool to move to the pole tube transfer component, and the clamping component 23 fixes the wire rack 105. The pole tube transfer component The parts combine the pole tubes at the pole tube transfer station onto the wire rack 105 on the workpiece positioning fixture, and then the rotating disk drives the workpiece positioning fixture to move to the clamping component three 37 to be clamped, and the second welding assembly performs welding between the pole tube and the wire rack 105. Then, the rotating disk drives the workpiece positioning fixture to the clamping component four 46 to be clamped, and the electrical performance detection component 40 and the detection camera two 45 perform detection of relevant parameters. Finally, the wire rack 105 is placed on the transfer unloading station through the unloading transfer component 49. The unloading component moves the qualified products to the unloading station, and moves the unqualified products (unqualified workpieces if any of the above processes do not meet the requirements) to the unqualified product unloading conveyor belt 53.

[0078] When using the equipment of this solution, place the housing 106 and the wire rack 105 on the wire rack 105 placement tooling and the housing 106 placement tooling on the tray 3 respectively. At the same time, place the cover plate 103 and the iron core 104 on the combined positioning tooling 56 successively. Start the equipment. The first press descends to combine the cover plate 103 and the iron core 104 on the combined positioning tooling 56. Subsequently, the first press resets, and the moving component 13-1 takes out the cover plate 103 and the iron core 104. At the same time, the upper turning component 60 on it turns 180° in the vertical direction, so that the iron core 104 and the cover plate 103 are in a "丄" shape and then placed at the processing positioning tooling 62 on the tray 3. Subsequently, the double-speed chain drives the tray 3 to move to the housing 106 assembly component 63. The housing 106 assembly component 63 drives the first clamping part 66 and the second clamping part 67 to move above the housing 106 simultaneously and then descend to clamp the outer shell. Subsequently, the outer shell is moved to the wire rack 105 and sleeved on the wire rack 105. At this time, the second clamping part 67 extends into the tubular structure of the wire rack 105 and expands radially to complete the tightening of the wire rack 105. Subsequently, the first clamping part 66 and the second clamping part 67 jointly drive the housing 106 and the wire rack 105 to move to the processing positioning tooling 62, so that the housing 106, the wire rack 105, the cover plate 103 and the iron core 104 are combined together (at this time, they are not tightened and are in a loose state). Subsequently, the sixth clamping jaw 73 on the transfer component 29-2 inserts under the cover plate 103 and moves the whole to the processing positioning tooling two 94 on the turntable; Then, the vibrating disk feeds the magnetic circuit bottom plate 102 to the magnetic circuit bottom plate 102 feeding positioning tooling 76. The positioning component makes the rotating support shaft 79 support the magnetic circuit bottom plate 102 and带动其旋转至需求位置,随后,磁路底板102组装组件带动磁路底板102安装至工件定位工装上的线架105上,接着,压装组件二83对自上至下对工件整体进行压紧,然后,通过焊接组件进行焊接,激光打码机进行打码,扫码机扫码,对于无法扫码的由不合格下料组件运至下料输送带53上运走,而产品下料组件则将合格产品取出放置托盘3上加工定位工装一62上,至此完成产品的组装成型,而在转动盘的作用下,根据产线设定匹配的运行参数,即使得整个生产线能够让每个产品按工序依次进行批量的生产。
