Description

Technical Field

[0001] This utility model relates to an automatic detection device for electrical components. Background Technology

[0002] Existing relay testing methods generally employ manual and semi-automatic approaches. Semi-automatic testing involves manually loading the relay into a designated position for testing. However, these methods have limitations. Manual testing relies heavily on the operator's experience and skill level, resulting in low efficiency and susceptibility to human error. For instance, manually reading voltmeter or ammeter readings when testing the contact status of relay contacts is time-consuming and prone to misjudgment due to improper operation. Furthermore, manual testing cannot achieve high-precision continuous monitoring, failing to meet the high performance requirements of modern industry. While semi-automatic testing improves efficiency to some extent, it still requires manual intervention, such as manual loading and unloading. This method typically involves manually placing the relay into the designated position before starting the testing equipment for performance testing. Moreover, existing methods use two screwdrivers to tighten the relay, which becomes unusable when there is a significant error between the two holes of the relay. Therefore, designing an automated testing device that is adaptable to various specifications and facilitates tightening is the research direction of this invention. Utility Model Content

[0033] A fastening assembly 50 is provided on one side of the opening end of the workbench 301 for fastening the relay.

[0070] Operation procedures for Example 1 and Example 2:

[0071] The relays are sequentially conveyed to the clamping mechanism 20 via the conveying mechanism 10. The clamping mechanism 20 clamps the relays and performs preliminary testing. The relays are then conveyed to the fastening pin detection and fixing mechanism 30, triggering the position sensor. The first cylinder 3032 starts to operate, pushing the sliding base 303 to move on the first guide rail 304, which in turn moves the fastening pin assembly 50 to a predetermined position. The second cylinder 502 is activated, pushing the second connecting plate 503 towards the relay to perform the fastening operation. The relay moves to the outer side of the opening end of the workbench 301 and enters the operating range of the circuit connection test assembly 70. The third cylinder 701 starts to operate, pushing the moving plate 702 to move upward along the third guide rail 704 on the vertical frame 703. The second motor 707 is activated, driving the test connector 710 downward via the shaft 708 to perform circuit testing on the relay. Relays that pass the circuit testing are conveyed to the storage mechanism 40 for storage, while defective relays are recycled through the recycling channel on one side of the storage mechanism 40.

[0072] The above examples demonstrate the application of automated equipment in the production of relays of different models and sizes, showcasing the significant effects of automation technology in improving production efficiency, ensuring product quality, reducing costs, and enhancing operational safety. Automated equipment can continuously and accurately perform operations such as relay feeding, clamping detection, fastening detection, and storage, significantly reducing manual intervention and thus lowering labor costs and operational error rates. Simultaneously, by precisely controlling the movements of key components such as cylinders, sliders, and guide rails, high precision and consistency in fastening operations are ensured, improving the quality of the final product. Furthermore, the design of automated equipment considers adaptability to different environmental conditions, enhancing the stability and reliability of the production line. The equipment may also be equipped with a fault diagnosis system to facilitate timely detection and resolution of potential problems, reducing equipment downtime and further improving production continuity. In summary, these two examples demonstrate that the application of automation technology in the relay manufacturing process can effectively optimize production processes, improve economic efficiency, and provide operators with a safer and more efficient working environment.

[0073] Working principle:

[0074] This embodiment achieves a fully automated process for relays from delivery to final storage through the coordinated operation of a series of precisely designed mechanisms. First, the delivery mechanism 10 sequentially delivers the relays into the equipment. The relays move along the delivery track and enter the subsequent clamping and testing stage. In this stage, the clamping mechanism 20 clamps and performs preliminary testing on the relays, using a robotic arm or fixture to secure them and ensure their stable position during subsequent testing. Basic checks, such as visual inspection and dimensional measurements, may also be performed to ensure the relays meet basic requirements. The relays are then delivered from the clamping mechanism 20 to the fastening and fixing mechanism 30, which includes a support frame 300 and a worktable 301. Inside the open end of the worktable 301, the fastening assembly 50 performs the first fastening operation on the relays. When the relays reach the designated point on the worktable 301... When the device is positioned, the first cylinder 3032 starts working, and its extension and retraction movement drives the sliding base 303 to move along the first guide rail 304 to the predetermined fastening position. The positioning angle plate 3036 ensures that the fastening assembly 50 is accurately aligned with the fastening point of the relay. The fastening assembly 50 includes a vertical base plate 500, a first connecting plate 501 and a fourth connecting plate 512. A second cylinder 502 is provided on the first connecting plate 501. The output end of the second cylinder 502 is connected to the second connecting plate 503. When the second cylinder 502 is activated, it pushes the second connecting plate 503 to move towards the relay to perform the fastening operation. The first guide limit rod 504 ensures the stability and accuracy of the fastening action. The second slider 506 and the third slider 507 are on the second guide rail 505. The sliding mechanism, with the second slider 506 connected to the connecting seat 508-0 and the third slider 507 connected to the third connecting plate 508 working together, further ensures the accuracy of the fastening position. The first motor 600 on the clamping seat 60 is activated, driving the fastening knife 601 to fasten the relay. The fastening knife 601, through the mechanical structure on the clamping seat 60, precisely fastens the relay's pins. On the outer side of the open end of the workbench 301, immediately after the relay moves to the position of the circuit connection test assembly 70, the third cylinder 701 extends after receiving the control signal, pushing the moving plate 702 upward along the third guide rail 704 on the vertical frame 703, causing the test connector 710 connected to the bracket 706 to approach the relay under test. In the electrical system, the third slider 705 ensures that the moving plate 702 moves smoothly and accurately to the predetermined position. Simultaneously, the second motor 707 is activated, driving the test connector 710 to further approach the relay's circuit contact point via the shaft 708. The second spring 709 provides the necessary contact force to ensure a good electrical connection between the test connector and the circuit contact point, achieving circuit continuity testing. The test result is fed back to the control system through the test connector 710. The control system determines whether the relay circuit is normally connected based on the feedback information. After the test is completed, the third cylinder 701 retracts, and the moving plate 702 descends along the third guide rail 704 under the guidance of the third slider 705. The test connector 710 resets under the action of the second spring 709.In preparation for the next test, the circuit continuity testing component 70 automates, efficiently, and accurately tests the continuity of the relay circuit, improving production efficiency and testing reliability, reducing the need for manual operation, and ensuring product quality. After the clamping component 50 and the circuit continuity testing component 70, the relay is conveyed to the storage mechanism 40, which is responsible for neatly storing the relays after clamping testing, completing the entire automated process. In summary, throughout the process, each mechanism, through precise mechanical design and pneumatic control, achieves automated relay conveying, clamping detection, clamping detection, circuit testing, and storage, improving production efficiency and testing accuracy, reducing the need for manual operation, and ensuring consistent product quality.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
