DETAILED DESCRIPTION

[0028] The present invention discloses an adapter device for assembling and testing electrical components with a micro plug. The adapter device can achieve the following functions:

[0029] 1) Automated assembly and testing of small-sized electrical components;

[0030] 2) Short circuit during product circulation;

[0031] 3) Connectivity with testing equipment during product testing.

[0032] The present invention provides an adapter device for assembling and testing electronic components with miniature plugs, comprising a socket fixing cover plate, an adapter socket, a wire carrier assembly, an adapter connector (male and female), a connector fixing shell (male and female), a transfer support (for assembly and transfer), and a detection equipment adapter seat (for testing). The adapter socket shell is designed as a step surface, which is fixed on the adapter socket fixing seat on the plane of the wire carrier. The cover plate is screwed onto the wire carrier assembly, and the wires pass through the wire groove of the wire carrier assembly and extend from the bottom. The two wires are respectively connected to the two poles of the adapter connector (female). The adapter connector (female) is inserted into the connector fixing shell (female), and the fixing shell (female) is screwed into the wire carrier. When the product needs to be short-circuited, the two poles of the output end of the adapter connector (male) are welded. The adapter connector (male) is inserted into the connector fixing shell (male) and screwed onto the transfer support or the detection equipment interface.

[0033] After the transfer socket wire is connected to the transfer connector, the wire connector is connected to the wire carrier assembly, thus forming an open-circuit transfer structure, which expands the docking area and improves the docking reliability.

[0034] This device is suitable for electrical components with miniature plugs that contain leads of varying lengths. The plug size is generally less than 5mm×3mm. The adapter socket housing is stepped, and its overall size is smaller than the diameter of the fixed end face of the wire carrier. The socket can be inserted from the top and then fixed horizontally in the groove of the wire carrier. The cover is screwed onto the wire carrier body to fix the adapter socket. The wire carrier body is made of insulating material, with a fixing groove for the adapter socket on the top, a wire hole in the middle, and a threaded hole at the bottom. The leads of the adapter socket pass through the wire carrier body and are welded to the two poles of the adapter connector (female). The adapter connectors (male and female) are interference fit with the connector fixing housing (male) and the connector fixing housing (female) respectively. The connector fixing housing is made of insulating material. The outer diameter of the connector fixing housing (female) is machined with a threaded surface, which mates with the thread at the bottom of the wire carrier body. The outer diameter of the connector fixing housing (male) is machined with a threaded surface, which mates with the thread of the flow support or the interface of the detection equipment. The adapter connector consists of two male and female parts, using either magnetic attraction or plug-in connection to ensure clear position limits and force feedback when connected. When used in automated assembly processes, the two poles of the male adapter connector are welded together to short-circuit the electrical components. When used in automated testing, the male adapter connector is connected to the interface of the testing equipment to complete the electrical performance test of the electrical components.

[0035] An embodiment of the present invention provides a method for automatically assembling and testing an explosive device with a lead and a miniature plug, comprising:

[0036] 1. Realize the short circuit of connectors of micro plug electrical components during automatic assembly;

[0037] 2. Realize the connection between micro plug electrical components and detection equipment during automatic detection.

[0038] The technical solution provided by the present invention, through the design of an adapter, transforms the short-circuiting requirements and docking accuracy requirements for miniature plugs in automated assembly and testing production lines into those for the adapter. This ensures short-circuiting safety during assembly of small-scale explosive devices while also meeting the docking requirements for automated testing.

[0039] The above is the core idea of ​​the present application. The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented using other embodiments different from those described herein. Those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Figure 1 This is a schematic diagram of the structure of an automatic assembly / testing device for explosive devices with leads and micro-plugs, provided by an embodiment of the present invention. The device comprises a support assembly 2, a wire carrier assembly 4, and an adapter socket cover 3. The leaded explosive device 1 comprises a main body 101, leads 102, and a connector 103. The wire carrier assembly 4 includes an adapter socket 401, a wire carrier body 402, and an adapter electrical connector II 403 (i.e., a female adapter connector).

[0041] A QR code is engraved on the adapter socket fixing cover 3. By binding it with the QR code information of the igniter through the control system, the quality data recording and traceability of the igniter assembly process can be realized.

[0042] The support assembly 2 consists of a guide fixing end 201, a fixed end 207, and a main support 205. Both the guide fixing end and the fixed end have connection interfaces that connect directly to the conveyor platform of the product assembly line. The main support 205 is used to accommodate explosive devices and transfer carriers. Once the guide fixing end 201 is connected to the production line conveyor platform, it limits the main support's Z-axis movement. After the guide fixing end is installed, the main support 205 is slid into place from the side.

[0043] After connecting to the production line conveyor platform, the fixed end 205 is connected to the main support, limiting the support's displacement in the X and Y directions. The main support structure consists of two parts: one end is the fixed end 202 of the pyrotechnic device, and the other end is the adapter carrier placement end 206, which is used to fix the short-circuit connector or the detection device adapter connector. In addition to the connection interface, the fixed end of the pyrotechnic device also has an exhaust port 204 to facilitate the smooth placement of the pyrotechnic device.

[0044] A rubber or other soft sealing ring 203 is embedded inside the fixed end of the main body of the pyrotechnic device to ensure that the igniter remains fixed under normal vibration conditions after being placed. The adapter carrier can be a magnetic connector or other connector with stable resistance. When the adapter electrical connector I (i.e., the adapter connector (male) mentioned above) 208 is welded at two levels, the adapter electrical connector II 4031 in the wire carrier assembly is connected to the adapter electrical connector I (magnetic connection or plug-in structure) at the placement end of the main support adapter carrier, the short-circuit function of the pyrotechnic device circuit can be met, and the fixing function of the adapter carrier can be met at the same time. When it is necessary to be conductive during testing, the two poles of the adapter electrical connector I 208 remain in their original state.

[0045] The adapter socket leads pass through the wire carrier body and are connected to the insulated outer cover 4031 of the adapter electrical connector II via two-stage welding. The adapter connector has an interference fit with the connector fixed housing 2 and connector fixed housing 1, respectively. The connector fixed housings are made of insulating material. The outer diameter of connector fixed housing 1 is machined with a threaded surface to mate with the threads at the bottom of the wire carrier. The outer diameter of connector fixed housing 2 is machined with a threaded surface to mate with the threaded interface of the flow support or testing equipment. The adapter connector is a male and female component, and can be magnetically connected or plugged in, ensuring clear limit stops and force feedback when connected.

[0046] It should be noted that the wire carrier body 402 is a non-metallic injection molded part, ensuring that it does not interfere with the electrical performance of the internal leads. The outer surface can be used to secure the pyrotechnic lead 102. The test terminal uses a magnetic connector or other type of connector (male and female), which can achieve conductivity when connected and open circuit when disconnected, while also meeting the carrier's fixed requirements.

[0047] During loading, the pyrotechnic lead connector is plugged into the adapter plug on the wire carrier assembly. During assembly, a gripper robot removes both the pyrotechnic and the adapter carrier (with a cover), scans the code, and records the connection before transporting them to the assembly station to ensure the lead's shape is stable on the carrier. During testing, the gripper robot removes both the assembled product and the carrier simultaneously. At this point, the pyrotechnic is in an open-circuit state and is transported to the test station where it is placed into a test holder with the same structure for a continuity test.
