[0016] The present invention aims to provide a back-end process for relay manufacturing, which belongs to relay automatic assembly equipment. Its function is to realize the automatic assembly of relay core, relay housing and gasket. At the same time, during the assembly process, two markings on the relay housing and automatic code scanning of the relay core are completed, and detection, classification and unloading after assembly are realized.Specifically, the present invention uses a machine table as a bearing structure, and a turntable mechanism is arranged on the machine table. The turntable of the turntable mechanism serves as a rotating platform, and a core loading station, a shell loading station, a gasket assembly station, a code scanning pre-assembly station and a second marking and assembly station are arranged at intervals along the circumferential direction thereof; it should be noted that each of the above-mentioned stations is respectively provided with two discharge positions at intervals, so as to place the relay core and the relay shell before assembly in parallel; a transfer loading platform is arranged on the side of the core loading station and the shell loading station, and a first moving arm and a second moving arm are arranged on the side of the transfer loading platform. After the relay core and the relay shell exported from the previous workstation are transferred to the transfer loading platform by the robot, they are respectively transferred by the first The lifting arm and the second lifting arm are moved to the discharge position at the core loading station and the shell loading station; then they are rotated to the gasket assembly station via the turntable, and while the gasket is automatically assembled at the gasket assembly station, the process of lifting the relay core upwards and placing the gasket by the material taking component during assembly effectively solves the interference problem of the relay core on the first marking of the relay shell, and solves the interference problem of the relay shell marking caused by parallel placement while realizing the gasket assembly; at the same time, after the gasket of the present invention is automatically exported by the gasket loading component, the gasket transfer component arranged between the gasket loading component and the turntable is used to realize cyclic loading and unloading by rotating back and forth, which effectively lifts the gasket The feeding efficiency of the sheet assembly is improved; after the gasket and the first marking are completed, the turntable rotates to the scanning pre-assembly station. At this station, the relay core needs to be scanned, and the relay housings placed in parallel will block the scanning path. Therefore, the pre-assembly and scanning actions are combined together. First, the relay housing is lifted up, and the relay core is scanned. The lifted relay housing avoids blocking the scanning. After the scanning is completed, the relay housing is inserted from above onto the relay core to complete the pre-assembly, which effectively improves the assembly efficiency; after the pre-assembly is completed, the turntable rotates to the second marking and assembly station, and the second marking gun marks the relay housing for the second time. It should be noted that Since the marking content information is different, it is necessary to mark the relay housing twice; at the same time, the pressing assembly outputs power from the upper and lower sides at this workstation to press and fasten the relay housing and the relay core to complete the assembly; since the connection between the relay housing and the relay core needs to be pressed by external pressure to be connected with each other, and the relay housing is a shell-like structure, it is easy to deform when it is under excessive pressure. Therefore, the pressing assembly of the present invention adopts an assembly method that combines lower pushing and upper pressing, and the relay core is pushed up by the upper pushing block below, and the relay housing is pressed down by the upper pressing profiling block to complete the mutual pressing and fastening of the two, which effectively reduces the deformation of the relay housing during the pressing process.

[0052] As an embodiment of the present invention, the present invention discloses an assembly process of a relay automatic assembly machine, comprising the following process steps: S1, loading transfer: the relay core and relay housing exported from the previous workstation are transported to the transfer loading platform; S2, relay core loading: the relay core on the transfer loading platform is moved to a discharge position at the core loading station by the first moving arm; S3, relay housing loading: After the relay core is loaded in step S1, the turntable rotates to the housing loading station, and the relay housing on the transfer loading platform is moved to another unloading position by the second moving arm; S4, gasket assembly and first marking: After the relay housing is loaded in step S3, the turntable rotates to the gasket assembly station, and the material taking component of the turntable mechanism clamps the relay core and lifts it upward; at the same time, the gasket exported by the gasket loading component is transported to the discharge position where the relay core is located by the gasket transfer component in a back-and-forth rotation manner; at the same time, the first marking gun performs the first marking on the relay housing, and then the material taking component places the relay core on the gasket; S5, scanning and pre-assembly of the core: After the gasket is assembled and the first marking is completed in step S4, the turntable rotates to the scanning pre-assembly station, and the material scanning mechanism lifts the relay housing upward, and its scanning gun scans the relay core, and then the lifted relay housing is placed on the relay core from above to complete the pre-assembly; S6, pressing assembly and second marking: After the pre-assembly in step S5 is completed, the turntable rotates to the second marking and assembly station, and the pressing assembly of the marking pressing mechanism pushes up the relay core from below, and then presses down the relay housing from above, so that the connecting buckles of the relay core and the relay housing are buckled and fixed to each other; then, the second marking gun of the marking pressing mechanism performs a second marking on the relay housing; S7, inspection and unloading: After the pressing assembly and the second marking in step S6 are completed, the CCD camera is used for inspection. The good products after inspection are transported to the unloading transfer table for buffering, and the defective products after inspection are transported to the NG platform for buffering.

[0053] Furthermore, the present invention also includes a first marking gun 10, a third lifting arm 14 and a material unloading mechanism, wherein the first marking gun 10 is arranged on the outside of the gasket assembly station C so that the first marking can be performed on the relay housing when the gasket is assembled; the material unloading mechanism includes a material unloading turntable 6 and an NG platform 15 arranged on the side of the turntable 71 in a straight direction, and strip storage grooves are respectively provided in the material unloading turntable 6 and the NG platform 15, and the storage grooves of the two are connected to each other, and a material shifting assembly is provided at the connection between the two storage grooves, and the material shifting assembly is driven by a cylinder to extend to the paddle above the storage groove to move back and forth in a straight line, so as to shift the detected relay into the material unloading turntable 6 or the NG platform 15; the third lifting arm 14 is erected between the material unloading mechanism and the turntable 71, and is used to transport the assembled relay to the unloading mechanism.

[0054] It should be particularly noted that each assembly station on the turntable 71 of the present invention adopts a double discharge position setting, that is, it includes two discharge positions arranged in parallel, so that the relay core 01 and the relay housing 02 can be placed separately before assembly. During the marking process, the relay core 01 and the relay housing 02 arranged in parallel will block the marking path. To solve this problem, the present invention sets the first marking process for the relay housing 02 when the gasket is assembled. Since the gasket needs to be assembled to the lower part of the relay core, the relay core 02 is extracted upward by the material taking component of the turntable mechanism 7 to place the gasket 04, and at the same time, the relay core 02 is lifted upward. The relay core 02 leaves space for the first marking gun 10 to mark the relay housing 02; in addition, the relay core 01 needs to be scanned before assembly for information tracing. Based on the same problem, the relay housing 02 will block the scanning path. Therefore, the present invention combines the pre-assembly and scanning processes together. At the scanning pre-assembly station D, the relay housing 02 is first lifted up by the material scanning mechanism 11, and then scanned by the scanning gun 118. After the scanning is completed, the lifted relay housing 02 is placed on the relay core 01 from above, thereby completing the relay pre-assembly while avoiding scanning interference.

[0055] Furthermore, the present invention designs a relay automatic assembly machine and its assembly process that adopts a combination of parallel double discharge positions and multiple assembly stations to realize automatic independent feeding of relay core and housing, marking and gasket installation, code scanning pre-assembly, secondary marking and pressing assembly, and effectively improves assembly efficiency. The present invention aims to provide a back-end process applied to relay manufacturing, which belongs to relay automatic assembly equipment, and its function is to realize the automatic assembly of relay core, relay housing and gasket, and at the same time completes the two markings on the relay housing and the automatic code scanning of the relay core during the assembly process, and realizes the detection and classification of materials after assembly.Specifically, the present invention uses a machine table as a bearing structure, and a turntable mechanism is arranged on the machine table. The turntable of the turntable mechanism serves as a rotating platform, and a core loading station, a shell loading station, a gasket assembly station, a code scanning pre-assembly station and a second marking and assembly station are arranged at intervals along the circumferential direction thereof; it should be noted that each of the above-mentioned stations is respectively provided with two discharge positions at intervals, so as to place the relay core and the relay shell before assembly in parallel; a transfer loading platform is arranged on the side of the core loading station and the shell loading station, and a first moving arm and a second moving arm are arranged on the side of the transfer loading platform. After the relay core and the relay shell exported from the previous workstation are transferred to the transfer loading platform by the robot, they are respectively transferred by the first The lifting arm and the second lifting arm are moved to the discharge position at the core loading station and the shell loading station; then they are rotated to the gasket assembly station via the turntable, and while the gasket is automatically assembled at the gasket assembly station, the process of lifting the relay core upwards and placing the gasket by the material taking component during assembly effectively solves the interference problem of the relay core on the first marking of the relay shell, and solves the interference problem of the relay shell marking caused by parallel placement while realizing the gasket assembly; at the same time, after the gasket of the present invention is automatically exported by the gasket loading component, the gasket transfer component arranged between the gasket loading component and the turntable is used to realize cyclic loading and unloading by rotating back and forth, which effectively lifts the gasket The feeding efficiency of the sheet assembly is improved; after the gasket and the first marking are completed, the turntable rotates to the scanning pre-assembly station. At this station, the relay core needs to be scanned, and the relay housings placed in parallel will block the scanning path. Therefore, the pre-assembly and scanning actions are combined together. First, the relay housing is lifted up, and the relay core is scanned. The lifted relay housing avoids blocking the scanning. After the scanning is completed, the relay housing is inserted from above onto the relay core to complete the pre-assembly, which effectively improves the assembly efficiency; after the pre-assembly is completed, the turntable rotates to the second marking and assembly station, and the second marking gun marks the relay housing for the second time. It should be noted that Since the marking content information is different, it is necessary to mark the relay housing twice; at the same time, the pressing assembly outputs power from the upper and lower sides at this workstation to press and fasten the relay housing and the relay core to complete the assembly; since the connection between the relay housing and the relay core needs to be pressed by external pressure to be connected with each other, and the relay housing is a shell-like structure, it is easy to deform when it is under excessive pressure. Therefore, the pressing assembly of the present invention adopts an assembly method that combines lower pushing and upper pressing, and the relay core is pushed up by the upper pushing block below, and the relay housing is pressed down by the upper pressing profiling block to complete the mutual pressing and fastening of the two, which effectively reduces the deformation of the relay housing during the pressing process.

The technicians in this industry can make some modifications inspired by this embodiment, so any equivalent changes or modifications made according to the scope of the patent of the present invention are within the scope of the patent claims of the present invention.
