[0005] By adopting the above technical solution, the end face of the rotary worktable can rotate to drive each assembly station on the end face to assemble the conductive terminals by the terminal assembly mechanism and then rotate to the shell assembly mechanism and the first welding piece assembly mechanism to assemble the insulating shell and the left and right welding pieces. It is then rotated to the detection mechanism to detect whether the connector welding pieces on the assembly station are placed correctly after the preliminary assembly, and then rotated to the stamping mechanism to fix the welding pieces and the conductive terminals, and finally rotated to the unloading mechanism to transfer the assembled connector.

[0006] Furthermore, the end face of the rotating worktable is a disc-shaped structure, and there are multiple assembly stations evenly distributed on the end face of the rotating worktable. Each assembly station includes a base fixedly mounted to the end face of the rotating worktable, a fixing protrusion protruding from the base for fixing the insulating shell, and two sockets provided on the top of the fixing protrusion for inserting conductive terminals.

[0011] By adopting the above technical solution, the insulating shell can be smoothly transported from the second feeding vibration plate along the first feeding guide rail to the tail end of the guide rail, and then the robotic arm and cylinder clamp grasp and transfer the insulating shell to the fixed protrusion on the end surface of the rotating worktable.

[0012] Furthermore, the first solder piece assembly mechanism includes two third loading vibration plates arranged on the periphery of the rotary workbench for respectively storing and automatically conveying the left and right solder pieces, and a second feeding guide connected to the third loading vibration plate.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0032] like Figures 1 to 6As shown, an automatic assembly device for connector 9 can automatically assemble and inspect connector 9; wherein this embodiment includes a rotating worktable 1, and a terminal assembly mechanism 2, a shell assembly mechanism 3, a first welding piece assembly mechanism 4, a detection mechanism 6 for confirming that the welding piece 93 is correctly placed, a stamping mechanism 7 for fixing the welding piece 93 and a blanking mechanism 8 for transferring the assembled connector 9 to the next process are sequentially arranged on the side of the rotating worktable 1. A number of assembly stations 11 for fixing the various components of the connector 9 are arranged on the end face of the rotating worktable 1, and the rotating worktable 1 can drive the assembly stations 11 to rotate in sequence for assembly.

[0033] This embodiment is composed of a frame and a disc-shaped rotating worktable 1 mounted on the top end face of the frame. Other mechanisms are distributed around the rotating worktable 1, making the overall structure of the device compact and greatly reducing the floor space. An operating table with a screen installed on the worktable can be used by workers to operate and monitor the equipment, allowing one person to complete the work, saving human resource costs. There are also footrests under the frame for adjusting balance and preventing slipping. Multiple assembly stations 11 are evenly distributed on the edge of the end face of the rotating worktable 1, such as Figure 6 As shown, the assembly station 11 includes a base 111 fixedly mounted to the end surface of the rotary table 1, a fixing protrusion 112 protruding from the base 111 for fixing the insulating housing 91, and two insertion holes 113 provided on top of the fixing protrusion 112 for inserting the conductive terminals 92. When the device is activated, the terminal assembly mechanism 2 first places the two conductive terminals 92 into the insertion holes 113 of the assembly station 11. The rotary table 1 rotates, and the assembly station 11, which has been assembled with the conductive terminals 92, is transferred to the housing assembly mechanism 3. The housing assembly mechanism 3 automatically fits the insulating housing into the fixing protrusion 112 of the assembly station 11, and the conductive terminals 92 are inserted into the reserved holes in the insulating housing 91. At the same time, the empty assembly station 11 is also rotated to the terminal assembly mechanism 2 for assembly of the conductive terminals 92. After the insulating housing is assembled, the rotary table 1 rotates again, and the assembly station 11, which has been assembled with the conductive terminals 92 and the insulating housing, is rotated to the first soldering lug assembly mechanism 4 for assembly of the left and right soldering lugs 93. In order to ensure the quality of assembly, the connector 9 after preliminary assembly will then be transferred to the inspection mechanism 6, where the inspection mechanism 6 will check whether the position of the welding piece 93 is correctly placed. It will then be rotated to the stamping mechanism 7 to fix the welding piece 93 and the conductive terminal 92 to form a finished connector 9. Finally, it will be rotated to the unloading mechanism 8 to transfer the assembled connector 9, and the automatic assembly of the connector 9 will be realized in this cycle.

[0034] like Figure 2As shown, the terminal assembly mechanism 2 of this embodiment includes a first vibrating loading tray 21, located around the periphery of the rotating worktable 1, for storing and automatically transporting conductive terminals 92; two air guide tubes 22 connected to the first vibrating loading tray 21; a nozzle 23 at the end of the air guide tubes 22; and a first robotic arm 24 fixedly connected to the nozzle 23 for driving the nozzle 23 to align with the receptacle 113. The first vibrating loading tray 21, located around the periphery of the rotating worktable 1, is responsible for storing a large number of conductive terminals 92 to be assembled and automatically sorting and transporting them to the receptacle through a vibration mechanism. The two air guide tubes 22 seamlessly connect to the first vibrating loading tray 21. Using compressed air or vacuum, they smoothly and quickly transport the conductive terminals 92 from the vibrating tray to the end of the air guide tubes 22 through internal pipes. The nozzles 23 at the end of the air guide tubes 22 precisely control the discharge of the conductive terminals 92, ensuring that the conductive terminals 92 are accurately aligned with the receptacles 113 of the assembly station 11 on the end surface of the rotating worktable 1. In conjunction with the precise motion control of the first robotic arm 24 , the nozzle 23 can move to the correct position according to a preset program, align and gently push the conductive terminal 92 into the socket 113 .

[0035] like Figure 2 As shown, the shell assembly mechanism 3 of this embodiment includes a second loading vibration plate 31 arranged on the side of the rotating workbench 1 for storing and automatically conveying the insulating shell 91, a first feeding guide rail 32 connected to the second loading vibration plate 31, and a second robotic arm 33 arranged at the tail end of the first feeding guide rail 32. The second robotic arm 33 is provided with a cylinder clamp 34 for clamping and transferring the insulating shell 91 conveyed to the tail end of the first feeding guide rail 32 to the fixed protrusion 112. The second loading vibration plate 31 is located on the side of the rotary worktable 1 and has a larger volume than the first loading vibration plate 21. It is specially used to store a large number of insulating shells 91. The first feeding guide rail 32 connected to the second loading vibration plate 31 plays a role of precise guidance. Through the guide rail structure, the insulating shell 91 can be smoothly transported to the end of the guide rail along a predetermined path. The second robotic arm 33 can enhance the flexibility of assembly and is equipped with a cylinder clamp 34 at the end, which enables the robotic arm to accurately grasp and transfer the insulating shell 91 to the fixed protrusion 112 on the end face of the rotary worktable 1 to complete the assembly of the insulating shell.

[0036] like Figure 1 and Figure 3As shown, the first solder tab assembly mechanism 4 of this embodiment includes two third loading vibration trays 41 disposed on the periphery of the rotary worktable 1 for respectively storing and automatically conveying left and right solder tabs 93, and second feeding rails 42 connected to the third loading vibration trays 41. A third robotic arm 43 is disposed at the tail end of each second feeding rail 42. The third robotic arm 43 is equipped with a vacuum suction nozzle 44 for suction-transferring the left and right solder tabs 93 conveyed to the tail end of the second feeding rails 42 to the top of the conductive terminal 92. The two third loading vibration trays 41 and the second feeding rails 42 respectively store and automatically convey the left and right solder tabs 93. The third robotic arm 43 and the vacuum suction nozzle 44 then sequentially assemble the left and right solder tabs 93 onto the assembly station 11.

[0037] like Figure 1 As shown, in this embodiment, a second solder tab assembly mechanism 5 is further provided between the first solder tab assembly mechanism 4 and the detection mechanism 6. The second solder tab assembly mechanism 5 has the same structure as the first solder tab assembly mechanism 4 and is used to store and assemble solder tabs 93 of connectors 9 of other specifications. When solder tabs 93 of other specifications are needed, the first solder tab assembly mechanism 4 can be closed and the second solder tab assembly mechanism 5 can be activated.

[0038] like Figure 4 As shown, the detection mechanism 6 of this embodiment includes a lifting frame 61 disposed on the side of the rotating worktable 1, a detection pressure block 62 disposed on top of the lifting frame 61 and driven by the lifting frame 61 to be pressed down to the assembly station 11, and a sensor 63 disposed above the detection pressure block 62 for identifying the flatness of the detection pressure block 62 to determine whether a welding piece 93 is placed on the assembly station 11. Driven by the lifting frame 61, the detection pressure block 62 can be pressed down smoothly and accurately onto the assembly station 11, directly contacting the welding piece 93 or the surface of the connector 9. The sensor 63 located above the detection pressure block 62, such as a photoelectric sensor or a pressure sensor, can monitor in real time the changes in the flatness of the detection pressure block 62 during the downward pressing process. If it is found that the pressure block is unevenly pressed due to the missing or improperly positioned welding piece 93, the sensor 63 immediately feeds this information back to the control system, realizing instant recognition and judgment of the assembly status of the welding piece 93.

[0039] like Figure 2 As shown, the unloading mechanism 8 of this embodiment includes an unloading robot 81 for removing the assembled connector 9 from the assembly station 11 and a discharge chute 82 provided below the unloading robot 81. The unloading robot 81 can clamp the stamped finished connector 9 from the assembly station 11 and transfer it to the discharge chute 82 for transfer.

[0040] In summary, the beneficial effects of this embodiment are as follows: This embodiment sets up a rotating workbench 1, and sequentially sets up a terminal assembly mechanism 2, a shell assembly mechanism 3, a first welding piece assembly mechanism 4, a detection mechanism 6, a stamping mechanism 7 and a blanking mechanism 8 on the side of the rotating workbench 1, thereby forming equipment for automatic assembly of a connector 9. The realization of fully automated assembly line operations from raw materials to finished products greatly improves production efficiency, reduces dependence on manual operations, and reduces labor costs. The use of precise robotic arms, pneumatic systems, vacuum nozzles 44 and detection mechanisms 6 ensures high precision and reliability during the assembly process. Each connector 9 undergoes strict testing after assembly, effectively eliminating defective products and ensuring product quality consistency. Two sets of welding piece 93 assembly mechanisms can quickly switch between welding piece 93 assemblies of different specifications according to production needs, thereby enhancing the adaptability and flexibility of the production line and meeting the diversified production needs of products.

[0041] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
