Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and more specifically, to an X-ray secondary testing device. Background Technology

[0002] During the manufacturing process of electronic devices, it is essential to ensure that all internal components are present and free of foreign objects. Currently, X-ray detectors are generally used to scan the internal components and obtain images to determine the device's quality. However, when an X-ray detector scans an electronic device from only one angle, internal components may obstruct each other, preventing the acquisition of accurate image information regarding the actual number of components. Therefore, two common inspection methods are employed: first, using a single X-ray detector to scan the internal components in a 3-way rotation to determine quality; second, using two sets of X-ray detectors to scan the device from two mutually perpendicular angles. Both of these inspection methods are relatively expensive. Utility Model Content

[0022] Please refer to Figures 1 to 6 The present invention, the X-ray secondary detection device 100, includes a frame 10, two conveyor belt assemblies 20, an X-ray source 30, an X-ray detector 40, and a control system (not shown).

[0023] The conveyor belt assembly 20 includes a pulley bracket 21 horizontally fixed to the frame 10, two pulleys 22 rotatably connected to the front and rear ends of the pulley bracket 21, a conveyor belt 23 wound around the two pulleys 22, and a pulley drive module 24 for driving the pulleys 22 to rotate.

The first pusher is located in front of the detection port 41. A second pusher 70 is mounted on the pulley brackets 21 of the first conveyor belt assembly 201 to push the test piece to the side of the output end of the second conveyor belt assembly 202 away from the first conveyor belt assembly 201. The second pusher 70 is located behind the detection port 41. The X-ray source 30, the X-ray detector 40, the first pusher, and the second pusher 70 are all electrically connected to the control system.

[0024] Specifically, a mounting cover 11 is fixedly mounted on the upper part of the frame 10. The mounting cover 11 covers the two conveyor belt assemblies 20. The front and rear ends of the mounting cover 11 are provided with a front cover opening 111 and a rear cover opening 112 above the conveyor belts 23 of the two conveyor belt assemblies 20, respectively, to allow the test object to pass through. A top opening 113 is provided on the top of the mounting cover 11. The X-ray source 30 is fixedly mounted on the outer side of the top of the mounting cover 11, and the X-ray emission port 31 is directly opposite the top opening 113. A first mounting hole 114 is provided on the side wall of the mounting cover 11 away from the second conveyor belt assembly 202 in front of the detection port 41. The first pusher is fixedly mounted on the outer side wall of the mounting cover 11, and the output end of the first pusher extends through the first mounting hole 114 to the top of the conveyor belt 23 of the first conveyor belt assembly 201. The outer wall of the mounting cover 11 is provided with a mounting step 115, and an electrical control box 90 is mounted on the mounting step 115.

In this embodiment, the first pusher is an air nozzle. The second pusher 70 is an air nozzle.

[0025] When using this utility model X-ray secondary detection device, the test piece is placed at the rear of the conveyor belt 23 of the first conveyor belt assembly 201. The conveyor belt 23 of the first conveyor belt assembly 201 drives the test piece from back to front under the drive of the pulley drive module 24. When the test piece passes the first photoelectric switch 80, the control system controls the X-ray source 30 to emit X-rays from the X-ray emission port 31. When the test piece passes the detection port 41, the X-ray detector 40 scans the image signal of the device inside the test piece. When the test piece passes the second photoelectric switch 85, the image signal scanned by the X-ray detector 40 is processed by the image processing module and software processing module of the control system and then transmitted to the display 97 to form an image. When the displayed image meets the requirements, the object under test slides down from the front end of the conveyor belt 23 of the first conveyor belt assembly 201 for collection. When the displayed image does not meet the requirements, the first pusher pushes the object under test onto the conveyor belt 23 of the second conveyor belt assembly 202 and rolls it at an angle (e.g., 90 degrees). The object under test is then conveyed from front to back by the conveyor belt 23 of the second conveyor belt assembly 202. When it passes through the detection port 41 again, the X-ray detector 40 scans the image signal of the device inside the object under test. When the object under test passes through the first photoelectric switch 80 again, the X-ray detector 40 processes the scanned image signal through the image processing module and software processing module of the control system and transmits it to the display 97 to form an image. When the displayed image meets the requirements, the object under test slides down from the rear end of the conveyor belt 23 of the second conveyor belt assembly 202 for collection. When the displayed image does not meet the requirements, the second pusher 70 pushes the object under test out of the conveyor belt 23 of the second conveyor belt assembly 202 for collection. The detection port 41 of the X-ray detector 40 covers the conveyor belt 23 of the two conveyor belt assemblies 20. After the test piece rolls and slides onto the conveyor belt 23 of the second conveyor belt assembly 202, it flips at a certain angle and passes through the detection port 41 again. The X-ray detector 40 can scan the image signals of different angles inside the test piece and obtain different imaging images, thereby making a secondary judgment on whether the test piece is qualified.

[0026] This utility model X-ray secondary inspection device completes the inspection of the test piece from two different angles using a single X-ray inspection device, which greatly improves the inspection efficiency and saves inspection costs.

[0027] It should be noted that the second pusher 70 can also be installed at a corresponding position on the frame 10. The first pusher and the second pusher 70 can also be cylinders or other driving components. An additional set of conveyor belt assemblies, namely a third conveyor belt assembly, can also be provided. The third conveyor belt assembly is located on the opposite side of the second conveyor belt assembly 202 and the first conveyor belt assembly 201. The conveyor belt of the third conveyor belt assembly is located below the conveyor belt 23 of the second conveyor belt assembly 202. The detection port 41 simultaneously covers the conveyor belts 23 of all three sets of conveyor belt assemblies 20. The second pusher 70 pushes the defective test piece to the rear end of the conveyor belt of the third conveyor belt assembly. The conveyor belt of the third conveyor belt assembly transports the test piece from back to front. The frame or the pulley bracket 21 of the second conveyor belt assembly 202 is equipped with a third pusher at the output end of the conveyor belt of the third conveyor belt assembly for pushing the defective test piece out of the conveyor belt of the third conveyor belt assembly. Similarly, a fourth conveyor belt assembly and a fifth conveyor belt assembly can also be provided.
