Description

Technical Field

[0001] The present invention relates to the technical field of relay assembly, and particularly relates to a core riveting device for a relay. Background Art

[0002] A relay is an electronic control device that plays roles such as automatic regulation, safety protection, and circuit conversion in a 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, most relays are composed of components such as brackets, housings, coils, cores, and contacts. The assembly production process of the entire relay finished product is relatively complex. In order to improve the production efficiency of relays, relays are often disassembled into several independent unit components. After these independent unit components are produced, they are assembled together.

[0003] The prior art, such as the patent document with the Chinese patent application number 202420096149.3 and the publication date of November 12, 2024, discloses a relay assembly machine, which includes a feeding device, a turntable mechanism, and a height measuring device arranged along the conveying direction of the conveyor line. A plurality of carriers are evenly distributed on the turntable of the turntable mechanism, and a transfer device, an assembly device, a pre-assembly device, and a riveting device are sequentially arranged along the rotation direction of the turntable circumference. The conveyor line conveys the fixture carrying the yoke iron component and the contact component to the transfer device. The transfer device shuttles between the turntable mechanism and the conveyor line and is used to transfer the yoke iron component and the contact part from the fixture to the carrier. The assembly device aligns and assembles the coil provided by the feeding device onto the yoke iron component of the carrier to form an assembly body. The pre-assembly device assembles the contact component onto the assembly body. The riveting device is used to rivet and press the assembly body and the contact part component into a relay main body. The transfer device also takes the relay main body from the turntable mechanism and places it into the fixture on the conveyor line. The conveyor line conveys the relay main body to the height measuring device for detection and then continues to convey it for discharging.

[0004] However, like the prior art in this document, it only detects the height of the relay, and it cannot ensure a reliable inspection of the riveting effect. It does not well detect whether the core riveting meets the preset range. The core of the relay is an important part of the relay, and it usually needs to be riveted to other parts of the relay through a riveting device. Therefore, if the connection position of the 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 with other parts, resulting in the failure of the relay assembly and waste of resources. Summary of the Invention

[0005] The present invention provides a core riveting device for a relay. Through the riveting device of the present invention, the conveyance and riveting of the core are realized, and the riveted parts can be detected after riveting is completed, so as to distinguish defective products and facilitate subsequent assembly.

[0006] To achieve the above object, the technical solution of the present invention is: a core riveting device for a relay, including a riveting machine frame. A feeding turntable is provided at the center of the riveting machine frame, and a jig is provided on the feeding turntable. A moving reed plate feeding mechanism for conveying the moving reed plate to the jig is provided on the riveting machine frame at one end of the feeding turntable. A core feeding module for conveying the core to the moving reed plate is provided on the riveting machine frame on one side of the feeding turntable. A core riveting mechanism for riveting the core on the moving reed plate is provided on the riveting machine frame at the other end of the feeding turntable. A core detection mechanism for detecting the riveting position of the core is provided on the riveting machine frame on the other side of the feeding turntable. A core assembly mechanism is provided on the riveting machine frame on one side of the core detection mechanism close to the feeding turntable side, and the core assembly mechanism is used to transfer the riveted moving reed plate to the core detection mechanism; the core detection mechanism includes a detection component, a detection placement table and a reflection component. The detection component is arranged on the riveting machine frame through a detection bracket. A detection placement table is provided at the front end of the detection component. A reflection component is provided on the side of the detection placement table away from the detection component. The riveted moving reed plate is placed on the detection placement table. The detection component corresponds to the riveting position of the moving reed plate and the core and is used to detect whether the connection position between the core and the moving reed plate is closely attached and whether the inclination deviation between the bottom end of the core and the top end of the moving reed plate is within a preset range.

[0007] In the above structure, by setting a loading turntable on the riveting frame, working mechanisms can be arranged around the loading turntable, making the structure of the riveting frame compact and not prone to wasting space. When riveting, the moving spring plate feeding mechanism transports the moving spring plate to the jig, and then the loading turntable can drive the jig to rotate to the iron core loading module. Thus, the iron core loading module transports the iron core onto the moving spring plate, and then the jig continues to rotate to the iron core riveting mechanism. The iron core is riveted by the iron core riveting mechanism to connect and fix the iron core and the moving spring plate. After the riveting is completed, the moving spring plate continues to rotate through the loading turntable to the iron core assembly mechanism. The iron core assembly mechanism places the moving spring plate on the detection and placement table. Thus, the detection component takes pictures of the moving spring plate to detect the riveting position of the iron core. At the same time, by setting a reflection component, the detection component can more accurately take pictures and detect the riveting position of the iron core. After the detection is completed, the qualified moving spring plates can be grabbed by the iron core assembly mechanism and assembled on the moving spring part of the relay, or the unqualified moving spring plates can be transferred, thus distinguishing the defective products for subsequent assembly. Moreover, the image obtained by the reflection component can be detected through the reflection component arranged on the side, and the reliability of the connection position between the iron core and the moving spring plate can be detected from the side, further ensuring the reliability of the detection.

[0008] Further, the moving spring plate feeding mechanism includes a moving spring plate feeding movement module and a moving spring plate gripping device. A moving spring plate storage area for placing the moving spring plate is provided on the riveting frame. The moving spring plate feeding movement module drives the moving spring plate gripping device to move along the X-axis and Y-axis of the moving spring plate storage area. The moving spring plate gripping device includes a moving spring plate gripping base, a moving spring plate gripping cylinder, and a moving spring plate gripping suction cup. The moving spring plate gripping base is arranged on the moving spring plate feeding movement module. A moving spring plate gripping cylinder is provided on the moving spring plate gripping base. A moving spring plate gripping suction cup is provided on the piston rod of the moving spring plate gripping cylinder. The moving spring plate gripping cylinder drives the moving spring plate gripping suction cup to grip the moving spring plate and transfer it to the jig.

[0009] With the above settings, the moving spring plate feeding movement module drives the moving spring plate gripping cylinder to move on the moving spring plate storage area, and then the moving spring plate gripping cylinder drives the moving spring plate gripping suction cup to grip and transfer the moving spring plate from the moving spring plate storage area to the jig, thus realizing the transportation of the moving spring plate, with a simple and effective structure.

[0010] Further, a turntable driving component is provided on the riveting machine frame below the loading turntable. The turntable driving component drives the loading turntable to rotate. One or more fixtures are provided on the loading turntable. The turntable driving component drives the loading turntable to rotate to transfer the fixture to the position of the moving reed plate loading mechanism. The moving reed plate grabbing cylinder drives the moving reed plate grabbing suction cup to grab the moving reed plate onto the fixture. After the moving reed plate is placed on the fixture, the turntable driving component drives the loading turntable to rotate to transfer the fixture to the iron core loading module, and the iron core loading module conveys the iron core onto the moving reed plate on the fixture.

[0011] With the above settings, by providing the turntable driving component below the loading turntable, the loading turntable can rotate, facilitating the movement of the fixture to different positions.

[0012] Further, after the iron core loading module conveys the iron core onto the moving reed plate on the fixture, the turntable driving component drives the loading turntable to rotate to transfer the fixture to the iron core riveting mechanism. The iron core riveting mechanism includes an iron core transfer device and an iron core riveting device. The iron core riveting device is provided on the riveting machine frame. An iron core transfer device is provided between the iron core riveting device and the fixture. The iron core transfer device grabs and transfers the moving reed plate on the fixture to the iron core riveting device. The iron core riveting device includes a riveting base, a riveting component, a riveting driving motor, and a riveting workbench. The riveting base is provided on the riveting machine frame. A riveting workbench is provided on the riveting base. A riveting driving motor is provided on the riveting base above the riveting workbench. A riveting component is provided on the driving shaft of the riveting driving motor. The iron core transfer device grabs and transfers the moving reed plate on the fixture to the riveting workbench.

[0013] With the above settings, the moving reed plate on the fixture is transferred to the riveting workbench by the iron core transfer device, facilitating the riveting of the iron core. The riveting driving motor drives the riveting component to move downward to rivet the moving reed plate on the riveting workbench. At the same time, a first iron core grabbing device and a second iron core grabbing device are respectively provided on both sides of the iron core transfer device. The first iron core grabbing device and the second iron core grabbing device rotate on the iron core transfer device to respectively transfer the moving reed plate on the loading turntable to the iron core riveting device and transfer the riveted moving reed plate on the iron core riveting device to the loading turntable. In this way, after riveting is completed, the feeding and discharging operations can be synchronously realized by rotating the first iron core grabbing mechanism and the second iron core grabbing mechanism, improving the riveting efficiency.

[0014] Further, the riveting workbench includes a riveting placement table, a riveting fixed seat, a riveting connecting plate, and a riveting buffer spring. The riveting fixed seat is arranged on the riveting base. The riveting connecting plate is sleeved on the side wall of the riveting fixed seat. A riveting buffer spring is provided between the bottom end of the riveting connecting plate and the riveting fixed seat. A riveting placement table is provided at the top end of the riveting connecting plate. A riveting hole is provided at the center of the riveting placement table. A riveting thimble is provided at the top end of the riveting fixed seat. The riveting thimble passes through the riveting hole and abuts against the moving spring plate located on the riveting placement table. The riveting driving motor drives the riveting component to move downward and cooperates with the riveting thimble to clamp the moving spring plate and the iron core to achieve riveting.

[0015] With the above settings, by providing a riveting buffer spring between the riveting connecting plate and the riveting fixed seat, a certain buffering effect can be achieved when the riveting component moves downward. Thus, when the riveting component continues to move downward, the riveting thimble passes through the riveting hole and abuts against the moving spring plate. In this way, the moving spring plate and the iron core can be riveted by the cooperation of the riveting component and the riveting thimble.

[0016] Further, riveting stoppers are provided at the upper and lower ends of the riveting fixed seat, and a riveting limiting block located between the riveting stoppers is provided on the riveting connecting plate.

[0017] With the above settings, the riveting connecting plate is prevented from detaching from the riveting fixed seat by the action of the riveting stoppers.

[0018] Further, riveting guide bars protruding outward are provided on both sides of the riveting fixed seat, and riveting guide grooves corresponding to the riveting guide bars are provided on the riveting connecting plate. The riveting guide bars are slidably arranged up and down in the riveting guide grooves.

[0019] With the above settings, the riveting guide bars facilitate guiding when the riveting connecting plate moves up and down, and prevent the riveting placement table from shifting.

[0020] Furthermore, the iron core transfer device includes an iron core transfer bracket, an iron core lifting motor, an iron core rotating motor, an iron core transfer substrate, a first iron core grasping component, and a second iron core grasping component. The iron core transfer bracket is arranged on the riveting machine frame. An iron core lifting motor is provided on the iron core transfer bracket, and an iron core rotating motor is provided on the driving shaft of the iron core lifting motor. An iron core transfer substrate is provided on the rotating shaft of the iron core rotating motor. The first iron core grasping component is arranged at one end of the iron core transfer substrate, and the second iron core grasping component is arranged at the other end of the iron core transfer substrate. The first iron core grasping component and the second iron core grasping component respectively correspond to the fixture and the riveting workbench. After riveting is completed, the first iron core grasping component grasps the unriveted moving reed plate on the fixture while the second iron core grasping component grasps the riveted moving reed plate on the riveting workbench. The iron core rotating motor rotates to swap the positions of the first iron core grasping component and the second iron core grasping component, puts the riveted moving reed plate into the fixture, and the turntable driving component drives the feeding turntable to rotate to transfer the fixture to the position of the iron core detection mechanism.

[0021] With the above settings, through the arrangement of the first iron core grasping component and the second iron core grasping component, it is possible to simultaneously grasp the riveted moving reed plate and the unriveted moving reed plate. Then, the positions of the two moving reed plates are swapped by the iron core rotating motor, so that riveting does not need to stop and wait for the next moving reed plate, thus improving the riveting efficiency.

[0022] Furthermore, the iron core assembly mechanism grasps the moving reed plate on the fixture and places it on the iron core detection mechanism. The iron core assembly mechanism includes an iron core assembly frame, an iron core assembly moving module, an iron core assembly cylinder, and an iron core assembly suction cup. The iron core assembly frame is arranged on the riveting machine frame. An iron core assembly moving module is provided on the iron core assembly frame. The cylinder body of the iron core assembly cylinder is installed on the iron core assembly moving module through an iron core assembly cylinder plate. An iron core assembly suction cup is provided on the piston rod of the iron core assembly cylinder. The iron core assembly moving module drives the iron core assembly cylinder to move to the fixture on the feeding turntable. The iron core assembly cylinder drives the iron core assembly suction cup to move downward to adsorb the moving reed plate and place the moving reed plate on the iron core detection mechanism.

[0023] With the above settings, the iron core assembly mechanism facilitates grasping the moving reed plate and placing it on the iron core detection mechanism.

[0024] Furthermore, a moving reed component conveying component is also provided on the riveting machine frame below the iron core assembly mechanism. The moving reed component conveying component includes a first moving reed component conveyor belt and a second moving reed component conveyor belt. A relay placement fixture is provided on the first moving reed component conveyor belt. The iron core assembly mechanism places the moving reed plate whose riveting is detected to meet the preset range on the iron core detection mechanism on the moving reed component on the relay placement fixture, and places the moving reed component whose riveting is detected not to meet the preset range on the second moving reed component conveyor belt.

[0025] With the above settings, by setting the first moving spring piece conveyor belt and the second moving spring piece conveyor belt, it is convenient to distinguish the unqualified moving spring plates, and thus assemble the qualified moving spring plates on the moving spring pieces, which facilitates the subsequent relay assembly.

The moving spring plate grasping cylinder 23A drives the moving spring plate grasping suction cup 24A to grasp the moving spring plate 01A onto the fixture 12A. After the moving spring plate 01A is placed on the fixture 12A, the turntable driving component 13A drives the loading turntable 11A to rotate and transfer the fixture 12A to a position corresponding to the iron core loading module 10A. The iron core loading module 10A conveys the iron core 02A onto the moving spring plate 01A on the fixture 12A. By providing the turntable driving component 13A below the loading turntable 11A, the loading turntable 11A can be rotated, facilitating the movement of the fixture 12A to different positions. In this embodiment, the turntable driving component 13A is a prior art that drives the loading turntable to rotate through a conveyor belt driven by a motor, and will not be elaborated here.

[0041] As Figure 1 , Figures 4-7 shown in the figure, after the iron core loading module 10A conveys the iron core 02A onto the moving spring plate 01A on the fixture 12A, the turntable driving component 13A drives the loading turntable 11A to rotate and transfer the fixture 12A to the iron core riveting mechanism 3A. The iron core riveting mechanism 3A includes an iron core transfer device 31A and an iron core riveting device 32A. The iron core riveting device 32A is provided on the riveting machine frame 1A. An iron core transfer device 31A is provided between the iron core riveting device 32A and the fixture 12A.

By providing the riveting buffer spring 304A between the riveting connecting plate 303A and the riveting fixing seat 302A, a certain buffering effect can be achieved when the riveting component 322A moves downward. Thus, when the riveting component 322A continues to move downward, the riveting ejector pin 306A passes through the riveting hole 305A and abuts against the moving spring plate 01A. In this way, the moving spring plate 01A and the iron core 02A can be riveted by the cooperation of the riveting component 322A and the riveting ejector pin 306A, as Figure 6 shown, notch portions 010A are provided on four sides of the moving spring plate 01A, and mounting notches 3010A are provided at positions corresponding to the notch portions 010A on the riveting placement table 301A, so that it is convenient to place the moving spring plate 01A on the riveting placement table 301A and also convenient to remove it from the riveting placement table 301A.

The iron core transfer bracket 311A is arranged on the riveting machine frame 1A. An iron core lifting motor 312A is provided on the iron core transfer bracket 311A, and an iron core rotating motor 313A is provided on the drive shaft of the iron core lifting motor 312A.

The turntable driving component 13A drives the feeding turntable 11A to rotate to transfer the fixture 12A to the position of the iron core detection mechanism 4A. Through the arrangement of the first iron core grasping component 315A and the second iron core grasping component 316A, the riveted moving reed plate 01A and the unriveted moving reed plate 01A can be grasped simultaneously, and the positions of the two moving reed plates 01A are swapped by the iron core rotating motor 313A, so that riveting does not need to stop and wait for the next moving reed plate, thereby improving the riveting efficiency. In this embodiment, the first iron core grasping component 315A and the second iron core grasping component 316A are devices that grasp the moving reed plate 01A by opening and closing pneumatic fingers.

The riveted moving contact plate 01A is placed on the detection placement table 42A. The detection component 41A corresponds to the riveting position of the moving contact plate 01A and the iron core 02A. In this embodiment, the detection component is a device that emits a detection light beam by laser and then realizes detection through reflection by the reflection component. The reflection component 43A is a laser reflector. The reflection component 43A is vertically arranged and located on the opposite side of the detection component. If the connection between the iron core and the moving contact plate is unreliable and there is a gap, the detection component emits a laser beam, and the emitted light beam is reflected back after passing through the reflection component, thereby determining the position where the connection is unreliable. If the iron core and the moving contact plate are inclined, the light beam emitted from the upper end of the iron core is reflected back by the reflection component to form a reflected image, and then compared with a preset reliable image to determine whether it is within the qualified range, thereby determining the reliability of the connection between the iron core and the moving contact plate.

[0047] As Figure 1 and Figure 9 As shown, the iron core assembly mechanism 5A grabs the moving contact plate 01A on the fixture 12A and places it on the iron core detection mechanism 4A. The iron core assembly mechanism 5A includes an iron core assembly machine frame 51A, an iron core assembly moving module 52A, an iron core assembly cylinder 53A, and an iron core assembly suction cup 54A. The iron core assembly machine frame 51A is arranged on the riveting machine frame 1A. An iron core assembly moving module 52A is provided on the iron core assembly machine frame 51A. The cylinder body of the iron core assembly cylinder 53A is installed on the iron core assembly moving module 52A through an iron core assembly cylinder plate 55A. An iron core assembly suction cup 54A is provided on the piston rod of the iron core assembly cylinder 53A. The iron core assembly moving module 52A drives the iron core assembly cylinder 53A to move to the fixture 12A on the feeding turntable 11A. The iron core assembly cylinder 53A drives the iron core assembly suction cup 54A to move downward to adsorb the moving contact plate 01A and place the moving contact plate 01A on the iron core detection mechanism 4A. The iron core assembly mechanism 5A facilitates grabbing the moving contact plate 01A and placing it on the iron core detection mechanism 4A. In this embodiment, the iron core assembly moving module 52A is a device that drives the iron core assembly cylinder 53A to move by driving a lead screw to rotate by a motor or by driving a piston rod to extend and retract by a cylinder.

[0048] As Figure 1 and Figure 9As shown in the figure, a moving spring piece conveying component 6A is further provided on the riveting machine frame 1A below the iron core assembling mechanism 5A. The moving spring piece conveying component 6A includes a first moving spring piece conveyor belt 61A and a second moving spring piece conveyor belt 62A. A relay placing fixture (not shown in the figure) is provided on the first moving spring piece conveyor belt 61A. The iron core assembling mechanism 5A places the moving spring plate 01A that has been detected and riveted within a preset range on the iron core detecting mechanism 4A onto the moving spring piece on the relay placing fixture. The iron core assembling mechanism 5A places the moving spring piece 01A that has been detected and riveted outside the preset range on the iron core detecting mechanism 4A onto the second moving spring piece conveyor belt 62A. In this embodiment, the iron core detecting mechanism 4A is specifically used to detect the riveting position of the iron core and the moving spring plate, specifically to detect whether the connection position between the iron core and the moving spring plate is tightly fitted and whether the inclination deviation between the bottom end of the iron core and the top end of the moving spring plate is within the preset range. If the inclination deviation is within the preset range, the riveting of the moving spring plate is qualified; otherwise, it is unqualified. The relay placing fixture is conveyed to the next assembling device through the first moving spring piece conveyor belt 61A, and the unqualified moving spring plate is conveyed to the collecting device for unqualified products (not shown in the figure) through the second moving spring piece conveyor belt 62A. By setting the first moving spring piece conveyor belt 61A and the second moving spring piece conveyor belt 62A, it is convenient to distinguish the unqualified moving spring plate 01A, and thus assemble the qualified moving spring plate 01A onto the moving spring piece, facilitating subsequent relay assembly.

[0049] Working principle of the present invention: By setting a loading turntable 11A on the riveting machine frame 1A, working mechanisms can be arranged around the loading turntable 11A, making the structure of the riveting machine frame 1A compact and not easily wasting space. During riveting, the moving spring plate 01A is conveyed to the fixture 12A through the moving spring plate loading mechanism 2A, and then the loading turntable 11A can drive the fixture 12A to rotate to the iron core loading module 10A. Thus, the iron core 02A is conveyed to the moving spring plate 01A through the iron core loading module 10A. Then, the fixture 12A continues to rotate to the iron core riveting mechanism 3A, and the iron core 02A is riveted by the iron core riveting mechanism 3A to achieve the connection and fixation of the iron core 02A and the moving spring plate 01A. After riveting, the moving spring plate 01A continues to rotate through the loading turntable 11A to the iron core assembling mechanism 5A. The moving spring plate 01A is placed on the detection placing table 42A through the iron core assembling mechanism 5A. Thus, the moving spring plate 01A is photographed and detected by the detection component 41A to detect the riveting position of the iron core 02A. At the same time, by setting the reflection component 43A, the detection component 41A can more accurately detect the riveting position of the iron core 02A. After the detection is completed, the qualified moving spring plate 01A can be grabbed by the iron core assembling mechanism 5A and the moving spring plate 01A is assembled onto the moving spring piece of the relay or the unqualified moving spring plate 01A is transferred, so as to distinguish the defective products and facilitate subsequent assembly.
