Description

Technical Field

[0001] The invention relates to the technical field of relay assembly, and in particular to an iron core riveting device for a relay. Background Art

[0002] Relay is an electronic control device that plays the role of automatic adjustment, safety protection, circuit conversion, etc. in the circuit. In recent years, with the rapid development of new energy vehicles, charging piles and energy storage industries, the application of relays has become more and more extensive. Among them, relays are mostly composed of various components such as brackets, shells, coils, iron cores, contacts, etc. The assembly production process of the entire relay finished product is relatively complicated. In order to improve the production efficiency of relays, relays are often split into several independent unit components, and these independent unit components are assembled together after production.

[0003] Prior art, such as the Chinese patent application No. 202420096149.3 and the publication date of November 12, 2024, discloses a relay assembly machine, including a feeding device, a turntable mechanism and a height measuring device arranged along the conveying direction of the conveying line, a plurality of carriers are evenly distributed on the turntable of the turntable mechanism, and a transfer device, a assembling device, a pre-installation device and a riveting device are sequentially arranged on the circumference of the turntable along its rotation direction. The conveying line transfers the jig carrying the yoke assembly and the contact assembly to the transfer device, and the transfer device The device is arranged to move back and forth between the turntable mechanism and the transmission line, and is used to transfer the yoke assembly and the contact part from the jig to the carrier. The assembling device aligns and assembles the coil provided by the feeding device to the yoke assembly of the carrier to form a connected body. The pre-installation device assembles the contact assembly to the connected body. The riveting device is used to rivet the connected body and the contact part assembly into a relay body. The transfer device also takes the relay body from the turntable mechanism and places it in the jig of the transmission line. The transmission line transmits the relay body to the height measuring device for detection and then continues to transmit the next material.

[0004] However, the prior art of the document only detects the height of the relay, which cannot ensure a reliable inspection of the riveting effect, and does not detect whether the riveting of the iron core meets the preset range. The iron core of the relay is an important component of the relay, and it is usually necessary to rivet the iron core to other components of the relay through a riveting device. Therefore, if the connection position of the iron core riveting is incorrect but the height of the relay meets the requirements, or there is a large deviation in the riveting position, it is easy to cause the subsequent assembly to not correspond well to other components, thereby causing the relay assembly to fail and cause waste of resources. Summary of the invention

The core assembly moving module 52A drives the core assembly cylinder 53A to move to the fixture 12A of the feeding turntable 11A, and the core assembly cylinder 53A drives the core assembly suction cup 54A to move downward to absorb the movable spring plate 01A and put the movable spring plate 01A into the core detection mechanism 4A. The core assembly mechanism 5A facilitates the grabbing of the movable spring plate 01A and places it on the core detection mechanism 4A. In this embodiment, the core assembly moving module 52A drives the core assembly cylinder 53A to move by means such as a motor driving the screw rod to rotate or a cylinder driving the piston rod to extend and retract.

[0046] like Figure 1 and Fig. 9As shown, a dynamic spring member conveying component 6A is also provided on the riveting frame 1A below the core assembly mechanism 5A, and the dynamic spring member conveying component 6A includes a first dynamic spring member conveying belt 61A and a second dynamic spring member conveying belt 62A. A relay placement jig (not shown in the figure) is provided on the first dynamic spring member conveying belt 61A. The core assembly mechanism 5A places the dynamic spring plate 01A detected by the core detection mechanism 4A, whose riveting meets the preset range, on the dynamic spring member on the relay placement jig, and the core assembly mechanism 5A places the dynamic spring member 01A detected by the core detection mechanism 4A, whose riveting does not meet the preset range, on the second dynamic spring member conveying belt 62A. In this embodiment, the core detection mechanism 4A is specifically used to detect the riveting position of the core and the dynamic spring plate, specifically whether the connection position between the core and the dynamic spring plate is tightly fitted and whether the inclination deviation between the bottom end of the core and the top end of the dynamic spring plate is within a preset range; if the inclination deviation is within the preset range, the riveting of the dynamic spring plate is qualified, otherwise it is unqualified. The relay placement jig is conveyed to the next assembly device through the first spring conveyor belt 61A, and the unqualified spring plates are conveyed to the unqualified product collection device (not shown in the figure) through the second spring conveyor belt 62A.

[0047] The working principle of the present invention is as follows: by arranging a loading turntable 11A on the riveting frame 1A, a working mechanism can be arranged around the loading 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 loading mechanism 2A, and then the loading turntable 11A can drive the jig 12A to rotate to the core loading module 10A, thereby transporting the iron core 02A to the movable spring plate 01A through the core loading 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, so as to realize the connection and fixation of the iron core 02A and the movable spring plate 01A, and complete the process of riveting the iron core 02A. After riveting, the movable spring plate 01A continues to be rotated to the core assembly mechanism 5A through the loading turntable 11A, and the movable spring plate 01A is placed on the detection placement table 42A through the core assembly mechanism 5A, so that the movable spring plate 01A is photographed and detected by the detection component 41A, so as to detect the riveting position of the core 02A. At the same time, by setting the reflection component 43A, the detection component 41A can detect the riveting position of the core 02A more accurately. After the detection is completed, the qualified movable spring plate 01A can be grabbed by the riveting assembly mechanism 5A and the movable spring plate 01A can be assembled on the movable spring part of the relay or the unqualified movable spring plate 01A can be transferred, so as to distinguish the defective products and facilitate the subsequent assembly.
