[0069] The following is a further description of the specific implementation of the three-hole socket automatic assembly system of the present invention in conjunction with the embodiments given in the accompanying drawings. The three-hole socket automatic assembly system of the present invention is not limited to the description of the following embodiments.

[0070] The socket includes a base, a mounting frame, a mounting plate, a pressure plate, a protective door, a spring, a cover, a panel and copper parts. Different sockets contain different parts. The same parts may require different models and different assembly methods. For example:

[0071] For example, the NEW7-D10800 / NEW7-D10810A socket does not include a cover plate and a mounting plate. During assembly, you need to assemble the base with the copper sheet, then install the pressure plate, install the protective door and spring on the mounting frame, and cover the panel to complete the assembly.

[0072] For example, the NEW7-N10800 / NEW7-N10810 socket does not include a base and a mounting plate. The function of the base is replaced by the mounting frame. During assembly, the mounting frame needs to be assembled with the copper parts, and then the pressure plate, the protective door and spring, the cover plate, and the panel are installed to complete the assembly.

[0073] For example, for the NEW2-C10810 socket, when assembling, you need to assemble the mounting frame and the mounting plate, then install the base, install the copper parts, then install the pressure plate, install the protective door and spring, install the cover plate, cover the panel, and complete the assembly.

[0074] For example, for the NEW2-S10810 socket, when assembling, you need to assemble the mounting frame and the mounting plate, then install the base, install the copper parts, then install the pressure plate, install the protective door and spring, install the cover plate, cover the panel and the decorative frame, and complete the assembly.

[0075] The assembly of the top NEW7-D10800 / NEW7-D10810A socket is set as the first assembly method, and the others are the second, third, and fourth assembly methods from top to bottom. It should be noted that the same assembly method includes but is not limited to the socket of this model.

[0076] Since different types of sockets require different parts, models, and assembly sequences, if each socket requires a set of assembly systems for assembly, it will not only take up a lot of space but also be expensive. Therefore, putting these different types of sockets into a system for assembly can effectively reduce the floor space, reduce costs, and improve efficiency.

[0077] A three-hole socket assembly method of the present invention divides the parts of the socket into two parts, namely a connecting element part and a protecting element part. The connecting element part includes a copper part for connecting with a plug and components for effectively supporting the copper part, wherein the copper part includes an L / N / E pole copper sheet; the protecting element part includes components for protecting the plug. The types and models of the parts included in the connecting element part and the protecting element part in different sockets are different, which will be described in detail later.

[0078] like Figure 1 and Fig.10 As shown, the automatic assembly system of three-hole sockets includes a connection element assembly system 5, a protection element assembly system 6, an overall assembly system and a PLC controller, and the PLC controller is connected to the connection element assembly system 5, the protection element assembly system 6 and the overall assembly system. It also includes a carrier 59 arranged on the conveyor line, and the carrier 59 is provided with a first mounting groove 591 for assembling the connection element part of the socket and a second mounting groove 592 for assembling the protection element part of the socket.

[0079] The connection element assembly system 5 includes a mounting frame assembly unit, a base assembly unit and a first pressing plate assembly unit. The mounting frame assembly unit is used for loading and assembling the mounting frame and the mounting plate, the base assembly unit is used for loading and assembling the base and the copper parts, and the first pressing plate assembly unit is used to assemble the pressing plate onto the base in the carrier 59 to form the connection element part of the socket.

[0080] The protection element assembly system 6 includes a cover assembly unit 61, a door spring assembly unit and a second pressure plate assembly unit 63. The cover assembly unit 61 is used to assemble the cover onto the carrier 59, the door spring assembly unit is used to assemble the protection door and the spring together and then assemble them onto the cover in the carrier 59, and the second pressure plate assembly unit 63 is used to assemble the pressure plate onto the cover of the carrier 59 to form the protection element part of the socket.

[0081] The overall assembly system includes a semi-finished product loading unit 64, a complete assembly unit and a panel assembly unit 67. The semi-finished product loading unit 64 is used to install the assembled connection element part in the connection element assembly system 5 into the first installation groove 591, the complete assembly unit is used to assemble the protection element part in the first installation groove 591 and the protection element part in the second installation groove 592 to form a complete assembly product, and the panel assembly unit 67 is used to assemble the panel to the complete assembly product to form a final product and realize complete assembly.

[0082] The connecting element assembly system 5 and the protection element assembly system 6 are arranged in parallel, run separately, and then transported to the overall assembly system together. The connecting element assembly system 5 and the protection element assembly system 6 both adopt an annular conveyor line, respectively forming an annular annular assembly system, and a plurality of carriers 59 are arranged on the annular conveyor line. The overall assembly system can be arranged in the annular assembly system of the connecting element assembly system 5 or in the annular assembly system of the protection element assembly system 6. The connecting element assembly system 5 and the protection element assembly system 6 can both be combined with the overall assembly system to form an annular assembly system. Of course, the overall assembly system may not be arranged in the annular assembly system of the connecting element assembly system 5 and the protection element assembly system 6. In this embodiment, it is preferred that the protection element assembly system 6 is combined with the overall assembly system to form an annular protection element and overall assembly system, and the two annular assembly systems of the protection element and the overall assembly system and the connecting element assembly system 5 intersect and cooperate at the semi-finished product loading unit 64. The protective element and overall assembly system of the present invention are used to realize the assembly of the cover plate, spring, protective door, and pressure plate of the socket to form the protective element part of the socket, which is convenient for subsequent assembly; and can realize the automatic assembly of the connection element part and the protection element part of the socket, with high assembly efficiency. When the connection element assembly system 5 is combined with the overall assembly system, a ring-shaped connection element and overall assembly system is formed.

[0083] The automatic assembly system for three-hole sockets of the present invention divides the parts of the socket into a connecting element part and a protecting element part. After the connecting element part and the protecting element part of the socket are assembled separately, they are assembled into a final product. Such a division is convenient for assembling sockets of different models and specifications. Different connecting element parts and protecting element parts can be assembled in combination. In the case of occupying a relatively small volume, the combination is used to realize the assembly of various three-hole sockets.

[0084] The assembly methods of different types of sockets are as follows:

[0085] For example, the NEW7-D10800A / NEW7-D10810A socket does not include a mounting plate and a cover plate. During assembly, the base, copper parts, and pressure plate need to be assembled separately to form a connecting element part, which is assembled into the first mounting groove 591; then the mounting frame, protective door, and spring are assembled separately. The mounting frame of this type of socket is similar to the cover plate of other sockets, and plays two roles as the cover plate and the mounting frame. The cover plate and the mounting frame are integrated, and can also be called a cover plate. It is installed using the cover plate assembly unit 61 to form a protective element part, which is assembled into the second mounting groove 592; then the connecting element part and the protective element part are assembled, and the panel is covered to complete the overall assembly.

[0086] For example, the NEW7-N10800 / NEW7-N10810 socket does not include a base and a mounting plate. The function of the base is replaced by the mounting frame. The mounting frame of this type of socket includes the functions of the base and the mounting frame, which is similar to the base and the mounting frame being integrated, and can also be called a base. During assembly, the mounting frame and the copper parts need to be assembled separately, and the copper parts are installed on the mounting frame to form a connecting element part, which is assembled into the first mounting groove 591; then the protective door, spring, pressure plate, and cover plate are assembled separately to form a protecting element part, which is assembled into the second mounting groove 592; then the connecting element part and the protecting element part are assembled, and the panel is covered to complete the overall assembly.

[0087] For example, for a NEW2-C10810 socket, during assembly, the mounting frame and the mounting plate need to be assembled separately, the base and the copper sheet need to be assembled separately, and the base and the mounting frame need to be assembled to form a connecting element part, which is assembled into the first mounting groove 591; the protective door, spring, pressure plate, and cover plate need to be assembled separately to form a protecting element part, which is assembled into the second mounting groove 592; and then the connecting element part and the protecting element part need to be assembled, and the panel needs to be covered to complete the overall assembly.

[0088] For example, for a NEW2-S10810 socket, during assembly, the mounting frame and the mounting plate need to be assembled separately, the base and the copper sheet need to be assembled separately, and the base and the mounting frame need to be assembled to form a connecting element part, which is assembled into the first mounting groove 591; the protective door, spring, pressure plate, and cover plate need to be assembled separately to form a protecting element part, which is assembled into the second mounting groove 592; and then the connecting element part and the protecting element part need to be assembled, and the panel and the decorative frame need to be covered to complete the overall assembly.

[0089] It should be noted here that the same assembly method includes but is not limited to this type of socket.

[0090] By dividing the parts of the socket into two parts for separate assembly and then for common assembly, when the two parts are assembling different types of sockets, only the device related to a certain socket will be operated, and the assembly unrelated to the certain socket will be stopped, so that different types of sockets can be assembled in one system, and because the connecting element assembly system 5 and the protection element assembly system 6 can be operated separately, the time required for assembly is greatly reduced, thereby effectively improving the efficiency of assembly.

[0091] like Figure 1As shown, the connection element assembly system includes a mounting frame assembly unit, a base assembly unit and a first pressing plate assembly unit, and the carrier 59 arranged on the circular conveyor line is sequentially transmitted to the mounting frame assembly unit, the base assembly unit and the first pressing plate assembly unit. The connection element assembly system of the present invention includes a mounting frame assembly unit, a base assembly unit and a first pressing plate assembly unit, which are used to realize the assembly of the mounting frame, the base, the copper sheet and the pressing plate of the socket, forming the connection element part of the socket, which is convenient for subsequent assembly and has high assembly efficiency.

[0092] The mounting frame assembly unit includes a mounting frame assembly device 51, a first mounting plate assembly device 52 and a second mounting plate assembly device 53, and are arranged in sequence along the transmission direction of the annular conveyor line. The mounting frame assembly device 51 is used to assemble the mounting frame into the first mounting groove 591 of the carrier 59, the first mounting plate assembly device 52 is used to assemble the first mounting plate to the left side of the mounting frame, and the second mounting plate assembly device 53 is used to assemble the second mounting plate to the right side of the mounting frame.

[0093] Preferably, different types of three-pin sockets require different types of E-pole copper sheets, so different devices are used to install the required E-pole copper sheets according to different types of three-pin sockets. Figure 1 As shown, the base assembly unit includes a base assembly device 54, an E-pole copper sheet assembly device 55 and an L / N / E-pole copper sheet assembly device 56, and they are arranged in sequence along the transmission direction of the circular conveyor line. The base assembly device 54 is used to install the base on the mounting frame, the E-pole copper sheet assembly device 55 is used to assemble the E-pole copper sheet into the base, and the L / N / E-pole copper sheet assembly device 56 is used to assemble the L / N / E-pole copper sheet into the base, that is, the L-pole, N-pole and E-pole copper sheets can be installed. The E-pole copper sheet assembly device 55 is used to supplement the other types of E-pole copper sheets that are missing in the L / N / E-pole copper sheet assembly device 56. In this embodiment, the E-pole copper sheet assembly device 55 and the L / N / E-pole copper sheet assembly device 56 do not work at the same time. When the E-pole copper sheet assembly device 55 is working, the assembly mechanism of the E-pole copper sheet in the L / N / E-pole copper sheet assembly device 56 does not work; when the E-pole assembly mechanism in the L / N / E-pole copper sheet assembly device 56 is working, the E-pole copper sheet assembly device 55 does not work.

[0094] like Figure 1 As shown, preferably, the first pressing plate assembly unit includes a first pressing plate assembly device 57 and a pressing plate riveting device 58 and is sequentially arranged along the transmission direction of the annular conveyor line. The first pressing plate assembly device 57 is used to move the pressing plate into a base of a desired type, and the pressing plate riveting device 58 is used to assemble the pressing plate into a base of a desired type.

[0172] like Fig.23 , 24 As shown, the two types of E-pole copper sheets are first assembled with wiring terminals in the E-pole assembly unit, and then fed into the E-pole copper sheet assembly device 55. The E-pole assembly unit is used to assemble the E-pole copper sheets with the wiring terminals, that is, the E-pole copper sheets assembled in the E-pole copper sheet assembly device 55 are installed with wiring terminals, which further improves the efficiency of automated assembly. The E-pole assembly unit includes a loading device, a conveying mechanism and an assembly device. The loading device is divided into a copper sheet loading device for loading the E-pole copper sheets and a terminal loading device for loading the wiring terminals.

According to different situations, after determining which E-pole copper sheet and terminal block to assemble, the corresponding mechanism is controlled by PLC to accurately assemble the required E-pole copper sheet and terminal block. In this way, multiple E-pole copper sheets and terminal blocks can be assembled in one set of equipment, which greatly reduces the space occupied and has high compatibility compared to using one set of equipment for each E-pole copper sheet and terminal block.

[0176] When the protection element assembly system 6 is assembled, the cover plate of the appropriate type is first selected and assembled on the carrier 59 in its ring; then the carrier 59 moves to the door spring assembly unit 62, and the corresponding type of protection door and spring are assembled on the cover plate; the carrier 59 moves to the second pressure plate assembly unit 63, and the second pressure plate assembly unit 63 assembles the pressure plate on the cover plate to form the protection element part; the semi-finished product feeding unit 64 assembles the connection element part assembled by the connection element assembly system 5 into the first installation groove 591 of the carrier 59 in the protection element assembly system 6, and the protection element part is in the second installation groove 591 of the carrier 59. 2; the carrier 59 moves to the assembly unit, and one of the first pressing and capping device 65 or the second pressing and capping device 66 of the assembly unit works to assemble the protection element part and the connecting element part to form an assembled product.

The E-pole copper sheet assembly device 55 and the L / N / E-pole copper sheet assembly device 56 may both work, or only the L / N / E-pole copper sheet assembly device 56 may work; and a pressure plate is loaded into the first pressure plate assembly unit to form a connecting element part, which is sent to the protection element assembly system 6; the cover plate assembly unit 61 in the protection element assembly system 6 installs the mounting frame of this type of socket onto the carrier 59 (the mounting frame of this type of socket is similar to the cover plate of other sockets, and plays a role It has two functions, namely, a cover plate and a mounting frame, and is similar to a cover plate and a mounting frame that are integrated, and can also be called a cover plate), and assembles the protective door and the spring at the door spring assembly unit. One of the first door spring assembly mechanism 621 and the second door spring assembly mechanism 622 works to grab and assemble different protective doors with springs respectively, and installs them on the mounting frame to form a protective element. The second pressure plate assembly unit 63 does not work. The protective element part is assembled into the second mounting groove 592 of the carrier 59. The semi-finished product loading unit 64 assembles the connecting element part into the first mounting groove 591 of the carrier 59, and then the carrier 59 is transported to the first pressing and capping device 65 of the assembly unit to assemble the protective element part and the connecting element part to form a product.
