[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) Improve detection efficiency

[0015] The inspection machine uses a turntable mechanism. After the relay feeding mechanism transports the relay to the turntable mechanism, the guide assembly is used to promote the orderly flow of the relay on the turntable mechanism. Multiple inspection assemblies are arranged in sequence along the turntable mechanism, which can continuously inspect the relay without the need to frequently start and stop the equipment. This greatly reduces the inspection time and significantly improves the inspection efficiency. The guide strips and auxiliary guide wheel elements in the guide assembly cooperate with each other to ensure that the relay enters the inspection station quickly and accurately. The in-place detection assembly can quickly determine whether the relay is in place, paving the way for subsequent inspections, and further enhancing the consistency and efficiency of the inspection process. The material separation assembly adopts an arc-shaped array discharge channel and a high-pressure air nozzle design, which can quickly classify and discharge the inspected relays, avoiding jams and delays in the discharge process and speeding up the overall inspection speed.

[0016] 2) Ensure detection accuracy

[0017] The rear-projection inspection component's inspection camera is mounted at an angle, and combined with the adjustable panel light source at the bottom, it can inspect the relay housing from a unique perspective. The inspection bracket is adjustable, and the ruler on the rear-projection inspection bracket can precisely adjust the position and angle of the inspection camera and light source, ensuring a comprehensive and detailed inspection of the relay housing and accurately detecting appearance defects. The second and third inspection components inspect the relay housing from different angles, complementing the rear-projection inspection component to build a multi-faceted inspection system, effectively avoiding blind spots and improving inspection accuracy and reliability. The adjustable design of the guide component and the rubber sleeve on the output end of the stepper motor can reduce damage and interference to the relay during the guidance process, ensuring the stability of the relay during the inspection process and thereby improving inspection accuracy.

[0018] 3) Effectively clean dust

[0019] The first and second dust-blowing elements in the dust collection assembly are tilted relative to the surface of the turntable mechanism, enabling multi-angle blowing and dust removal of the relay housing. The flat air nozzle features a detachable design, facilitating replacement and maintenance, ensuring effective blowing. The dust collection hopper effectively collects blown dust, maintaining a clean testing environment and preventing dust from interfering with test results. It also helps protect the internal components of the equipment and extends its service life. The unloading assembly's arc-shaped unloading guide plate not only guides the unloading of tested relays but also prevents dust from being raised during the unloading process, ensuring a smooth and clean unloading process.

[0020] 4) Accurate classification of discharge

[0021] The arc-shaped array discharge channel design of the material separation component, combined with the high-pressure air nozzle, can accurately classify relays in different states and convey them to the corresponding discharge channel based on the detection results. This precise classification and discharge method reduces the errors caused by manual sorting and improves the accuracy and efficiency of product classification.

[0022] The high-pressure air nozzle setting can accurately control the force and direction of the air jet, ensuring that the relay enters the designated discharge channel accurately, further improving the accuracy and reliability of material distribution.

[0023] 5) Enhance equipment versatility

[0024] Several components of the inspection machine are adjustable, including the guide bar and first drive source of the guide assembly, the inspection bracket and light source of the rear-projection inspection assembly, and the dust blower and dust collection funnel of the dust collection assembly. This adjustability enables the equipment to adapt to the inspection needs of relay housings of varying specifications and models, eliminating the need for frequent equipment replacement and reducing production costs. The equipment's versatility is also reflected in its ability to be flexibly adjusted to meet diverse inspection requirements and standards. Whether improving inspection accuracy or adding more inspection items, these can be achieved by adjusting equipment components, providing greater flexibility and adaptability for production.
