They are mostly used in automated control circuits and play important roles in automatic regulation, safety protection, and conversion circuits.

[0003] The existing relay production process requires the assembly of components such as the iron core, the movable spring plate and the movable spring member, so that the existing production process cannot be fully automated and still requires multiple workers to perform on-site inspection and installation, resulting in limited production efficiency of the relay.

[0004] Prior art, such as the Chinese patent application No. 201822137474.7, published on October 25, 2019, discloses a relay production line, including a riveting core device, a bottom plate coil assembly device, a compression spring armature riveting device, a bottom plate coil comprehensive assembly device, a welding device, a tunnel oven device, and a vacuum leak detection device, wherein the riveting core device, the bottom plate coil assembly device, the compression spring armature riveting device, the bottom plate coil comprehensive assembly device, the welding device, the tunnel oven device, and the vacuum leak detection device are connected in sequence. The production line of this document can effectively solve the problem that the production process of relays in the prior art cannot be fully automated, realize the automated production of relays, reduce the demand for manpower, and improve production efficiency.

[0005] However, in the prior art of the document, riveting is performed directly on the conveyor line, that is, the conveyor line needs to be stopped during riveting and can only be conveyed forward after the riveting is completed. This causes the entire production process to be paused, thereby reducing production efficiency. Summary of the invention

The core assembly mechanism 5A places the dynamic spring plate 01A on the dynamic spring member on the relay placement jig, and the core assembly moving module drives the core assembly cylinder to move to the jig of the loading turntable, and the core assembly cylinder drives the core assembly suction cup to move downward to adsorb the dynamic spring plate to place the dynamic spring member on the relay placement jig. The structure is simple and effective.

[0060] like Fig. 9 As shown, a working method of a core riveting device comprises the following specific steps: (1) The movable spring plate feeding mechanism 20A conveys the movable spring plate 01A onto the jig 12A of the feeding turntable 11A.

[0061] (2) The loading turntable 11A rotates to drive the fixture 12A to move onto the core loading module 10A.

[0062] (3) The core loading module 10A conveys the core 02A onto the movable spring plate 01A.

[0063] (4) The loading turntable 11A continues to rotate, driving the fixture 12A to move onto the core riveting mechanism 3A.

[0064] (5) The core rivet mechanism 3A rivets the core 02A so that the core 02A and the movable spring plate 01A are connected and fixed.

[0065] (6) The first core grasping member 315A grasps the unriveted movable spring plate 01A on the jig 12A and transfers it to the riveting table 30A.

[0066] (61) After the riveting of the movable spring plate 01A on the riveting workbench 30A is completed, the first iron core grasping component 315A grasps the riveted movable spring plate 01A and places it on the jig 12A.

[0067] (62) The loading turntable 11A rotates so that the next unriveted movable spring plate 01A moves to the position of the core assembly mechanism 3A.

[0068] (63) After the riveting of the movable spring plate 01A on the riveting workbench 30A is completed, the first iron core grasping component 315A and the second iron core grasping component 316A act synchronously to grasp the movable spring plate 01A that has been riveted on the riveting workbench 30A and the movable spring plate 01A that has not been riveted on the jig 12A, respectively.

[0069] (64) The first core grasping member 315A and the second core grasping member 316A synchronously exchange the positions of the riveted movable spring plate 01A and the unriveted movable spring plate 01A.

[0070] (65) Repeat steps (61-64) to achieve an uninterrupted riveting cycle.

[0071] (7) The loading turntable 11A continues to rotate to move the riveted movable spring plate 01A to the core assembly mechanism 5A.

[0072] (8) The core assembly mechanism 5A grabs the riveted movable spring plate 01A and assembles it on the movable spring member of the relay.

[0073] The working principle of the present invention is as follows: by arranging a feeding turntable 11A on the riveting frame 1A, a working mechanism can be arranged around the feeding turntable 11A, thereby making the structure of the riveting frame 1A compact and not prone to wasting space. When riveting, the movable spring plate 01A is transported to the jig 12A through the movable spring plate feeding mechanism 2A, and then the feeding turntable 11A can drive the jig 12A to rotate to the core feeding module 10A, thereby transporting the iron core 02A to the movable spring plate 01A through the iron core feeding module 10A, and then the jig 12A continues to rotate to the core riveting mechanism 3A, and the core 02A is riveted by the core riveting mechanism 3A to achieve the connection and fixation of the iron core 02A and the movable spring plate 01A, and the movable spring plate 01A after riveting is completed continues to The loading turntable 11A is rotated to the core assembly mechanism 5A, and the movable spring plate 01A is assembled on the movable spring part of the relay through the core assembly mechanism, which is convenient for subsequent assembly. By setting the core transfer device, after the movable spring plate on the riveting workbench is riveted, the first core grabbing component and the second core grabbing component act synchronously to grab the riveted movable spring plate on the riveting workbench and the unriveted movable spring plate on the jig, respectively. The first core grabbing component and the second core grabbing component synchronously exchange the positions of the riveted movable spring plate and the unriveted movable spring plate, thus ensuring that the loading turntable does not need to stop and wait for the core riveting to be completed before continuing to rotate, so that the core riveting of the relay can be cyclically uninterrupted, thereby making the assembly production efficiency of the relay higher.
