Description

Technical Field

[0001] The utility model relates to the technical field of radar housing testing, in particular to a radar housing conductive testing mechanism. Background Art

[0002] Radar metal housings play a crucial role in radar systems. They are not only the first line of defense to protect sensitive internal electronic components of the radar from external environmental factors, but also need to meet specific electrical and mechanical performance requirements. Radar housings are widely used in multiple fields such as military, civil aviation, meteorological monitoring, traffic monitoring, security systems, industrial automation, etc. Their design and manufacturing need to strictly comply with relevant industry standards and specifications.

[0003] Conductive testing is a test method for evaluating the conductive ability of materials or structures. It is usually used to determine electrical characteristics such as the resistivity, conductivity, and dielectric properties of materials. Such tests are applied in many industries and fields, including but not limited to electronics, semiconductors, aerospace, automotive, materials science, etc.

[0004] The main reason for conducting conductive testing on radar housings is to evaluate and ensure their electromagnetic compatibility (EMC) and electromagnetic interference protection. At the same time, it is also a test to check whether the use of the radar housing is affected after painting, ensuring the stable use of the radar housing.

[0005] When conducting conductive testing on existing radar metal housings, it is usually necessary for workers to hold a conductivity meter and a test rod with both hands to test the metal radar housings one by one. This not only has a high degree of work repetition, but also a large work intensity, and at the same time, the manual efficiency is relatively low. Therefore, a radar housing conductive testing mechanism is proposed to solve the above problems. Content of the Utility Model

The conductivity meter is connected to the lifting component. The lifting component is arranged above the conveying component and is connected to the conveying component. Installation frames are provided on both sides of the conductivity meter. The lifting component includes a movable frame, a rotating member, and a connecting rod. The movable frame and the rotating member are both arranged on the installation frames. The connecting rod is arranged between the installation frames and both ends of the connecting rod are connected to the movable frame.

[0008] In the above description, for a further solution, rotating shafts are provided at both ends of the conveyor belt. A driven pulley is provided at one end of the rotating shaft close to the stepping motor. A driving pulley is provided at a position of the drive shaft flush with the driven pulley. The driving pulley and the driven pulley are connected to each other. One end of the stepping motor away from the drive shaft is fixedly connected to the support platform through a connecting plate; the rotating shaft is used to drive the conveyor belt and the rotating part to rotate, achieving the effect of synchronous linkage.

[0009] In the above description, for a further solution, linkage wheels are provided at both ends of the drive shaft. A linkage shaft is provided on one side of the mounting frame away from the rotating part. The linkage shaft passes through the mounting frame and is connected to the rotating part.

[0011] In the above description, for a further solution, the rotating part has a triangular structure. The three sides of the rotating part all adopt an inward concave structure. The three corners of the rotating part are all rounded corner structures. The inward concave structure of the rotating part abuts against the rotating wheel at the upper end of the bent part, and the rounded corner structure of the rotating part abuts against the rotating wheel at the lower end of the bent part; when the rotating part rotates, the inward concave structure and the rounded corner structure provide the effect of the movable frame moving up and down when active.

The movable frame drives the testing rod to move vertically back and forth through the connecting rod. When the metal shell enters the processing area through the conveying component, the adjusted testing rod will contact and test the upper surface of the metal shell when moving downward. The conveying component continues to drive the metal shell to move, thereby realizing the uniform detection effect in the conveying direction on the top surface of the metal shell, eliminating the need for staff to manually hold the testing rod to test the metal shell and reducing the work intensity of the staff.

[0024] The conveying component includes a conveyor belt 12, a stepping motor 13, and a driving shaft 14. The conveyor belt 12 is arranged below the connecting rod 5. A support platform 15 is filled in the middle of the conveyor belt 12. The stepping motor 13 is arranged on one side of the support platform 15. The driving shaft 14 is rotatably installed in the middle of the support platform 15, and both ends of the driving shaft 14 extend in a direction away from the support platform 15. Positioning protrusions 16 for positioning are distributed on the surface of the conveyor belt 12.

[0025] Rotating shafts 17 are provided at both ends of the conveyor belt 12. A driven pulley 18 is provided at one end of the rotating shaft 17 close to the stepping motor 13. A driving pulley 19 is provided at a position on the driving shaft 14 flush with the driven pulley 18. The driving pulley 19 and the driven pulley 18 are connected to each other.

[0028] The rotating member 4 has a triangular structure. All three sides of the rotating member 4 adopt a concave structure, and all three corners of the rotating member 4 are rounded structures. The concave structure of the rotating member 4 abuts against the rotating wheel 7 at the upper end of the bent portion 6, and the rounded structure of the rotating member 4 abuts against the rotating wheel 7 at the lower end of the bent portion 6.

[0029] The working process of the present utility model: After placing the sample of the metal shell directly below the test rod 11, manually rotate the rotating member 4 to fit the concave structure of the rotating member 4 with the rotating wheel 7 at the upper end of the bent portion 6 to ensure that the test rod 11 is at the lowest position. The staff adjusts the adjusting bolts 9 and nuts 25 at both ends of the connecting rod 5 to determine whether the test rod 11 can contact the sample. After determining that contact can be made, start the stepping motor 13. The stepping motor 13 drives the driven pulley 18 to rotate synchronously through the driving shaft 14 and the driving pulley 19. At the same time, the passive pulley 23 of the linkage wheel 21 belt rotates. The passive pulley 23 drives the rotating member 4 to rotate through the linkage shaft 22. When the rotating member 4 rotates, it contacts the rotating wheel 7. Due to the rotation of the rotating member 4, under the driving of the concave structure of the rotating member 4 and the acting force of rotation, the rotating wheel 7 will move towards the rounded structure of the rotating member 4, thereby driving the movable frame 3 to reciprocate up and down. When the staff places the sample on the conveyor belt 12, the conveyor belt 12 moves the sample towards the direction of the test rod 11. When it enters the working area of the test rod 11, the reciprocatingly lifting and lowering test rod 11 will uniformly detect the top surface of the metal shell in the conveying direction.
