Description

Technical Field

[0001] This utility model relates to the field of CR detection technology, specifically a pulsed laser device for industrial CR. Background Technology

[0002] With the development of computer technology and digital imaging technology, industrial CR inspection systems gradually emerged and began to be applied in the late 20th century. These systems replace traditional film with imaging plates, which absorb and store X-ray energy. The stored energy is then converted into digital signals by laser scanning and other methods, which are then processed and displayed by a computer, greatly improving inspection efficiency and image quality.

[0003] In industrial CR inspection systems, the CR system mainly uses an imaging plate (IP plate) to receive X-rays and record information about the object being inspected. When the X-rays penetrate the object, they leave a latent image on the IP plate. The main function of the pulsed laser device is to scan and excite the already exposed IP plate. The pulsed laser emits a laser beam of specific wavelength and energy, which shines on the IP plate, causing the energy stored in the IP plate due to X-ray exposure to be released in the form of visible light. This process is called photoexcitation luminescence (PSL). Subsequently, this visible light is collected by a special photodetector and converted into an electrical signal. After a series of processing steps, a digital image is finally formed.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In existing technologies, industrial CR inspection devices are used in various industries (such as aerospace, electronic components, or energy and power industries). When industrial CR inspection is used in the electronic components industry, it can detect the welding quality, packaging defects, and internal circuit connection of electronic components.

[0006] Currently, when pulsed laser devices are used for long-term testing, dust dispersed in the working environment can easily adhere to the surface of the testing lens. As time goes by, the dust continues to accumulate, which can have a significant impact on the testing accuracy. Utility Model Content

[0016] One end of the double-ended connecting pipe passes through the first housing and the third housing in sequence and extends into the interior of the third housing. The end of the double-ended connecting pipe located inside the third housing is connected to a flexible hose. One end of the flexible hose is connected to one side of the hollow rod. A third electric push rod is hinged to one side inside the third housing. The telescopic end of the third electric push rod is hinged to the bottom of one side of the hollow rod.

[0017] Preferably, the adjustment mechanism includes a fixed plate fixedly installed on the top inner side of the two support frames, and a first electric push rod is installed through the surface of the fixed plate, and a mounting bracket is fixedly installed on the telescopic end of the first electric push rod.

[0018] A first servo motor is mounted on one side of the mounting frame. The output end of the first servo motor passes through the mounting frame and extends to the inner side of the mounting frame. A lead screw is fixedly mounted on the output end of the first servo motor. One end of the lead screw is rotatably connected to the inner side wall of the mounting frame.

[0024] 1. Utilizing the detection mechanism, when the laser detector is inspecting electronic components, the air pump can work to inflate the inside of the first housing. When the gas enters the inside of the first housing, it is injected into the inside of the second housing through the connection between the rotating connector and the second housing. The gas is then blown onto the detection lens of the laser detector through the first nozzle. At the same time as the first nozzle blows air, the second servo motor works to drive the gear to rotate. The meshing connection between the gear and the gear ring drives the second housing to rotate, further improving the dustproof effect of the dustproof component. This achieves the advantage of preventing dust from adhering to the detection lens of the laser detector.

[0025] 2. After the laser detector has been used for a period of time, the second electric push rod pushes the first housing and dustproof component, causing the cleaning component to move down to the bottom of the laser detector's detection lens. At the same time, the third electric push rod pushes the hollow rod, making it parallel to the laser detector's detection lens. The double-headed connecting pipe and hose then cause the second nozzle to spray air. As the second housing rotates, it drives the hollow rod to spray air at the laser detector's detection lens. This achieves air cleaning of the laser detector's detection lens, preventing dust from adhering to the lens and affecting the laser detector's detection accuracy. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] Please see Figures 1-6 This utility model provides a technical solution: a pulsed laser device in industrial CR, including a conveyor belt 1, a support frame 2 for detection installed on the top of the conveyor belt 1, an adjustment mechanism 3 for movement installed inside the support frame 2, and a detection mechanism 4 installed inside the adjustment mechanism 3.

[0036] The adjustment mechanism 3 includes a fixed plate 31 fixedly installed on the top inner side of the two support frames 2. A first electric push rod 32 is installed through the surface of the fixed plate 31. A mounting frame 33 is fixedly installed at the telescopic end of the first electric push rod 32. A first servo motor 34 is installed on one side of the mounting frame 33. The output end of the first servo motor 34 passes through the mounting frame 33 and extends to the inner side of the mounting frame 33. A lead screw 35 is fixedly installed at the output end of the first servo motor 34. One end of the lead screw 35 is rotatably connected to the inner side wall of the mounting frame 33. A mounting plate 36 is threadedly connected to the surface of the lead screw 35. A laser detector 41 is installed through the surface of the mounting plate 36, and the fixed end of the second electric push rod 42 is installed through the bottom of the mounting plate 36.

[0037] In this embodiment, when the detection mechanism 4 detects electronic components, the first electric push rod 32 can work to drive the mounting bracket 33 to descend, so as to drive the detection mechanism 4 to descend and detect the electronic components at close range. The first servo motor 34 can drive the lead screw 35 to rotate, and use the threaded connection with the mounting plate 36 to drive the mounting plate 36 and the detection mechanism 4 on its surface to move laterally, so as to avoid the detection mechanism 4 from having dead angles during detection, which would affect the detection accuracy.

[0038] Two support frames 2 are each fixedly mounted with guide rails 37 on one side of each other. The front and rear sides of the mounting frame 33 are provided with sliding grooves that are adapted to the guide rails 37. The mounting frame 33 is slidably connected to the guide rails 37 through the sliding grooves. A strip hole 38 is provided on the surface of one support frame 2. The output end of the first servo motor 34 is slidably connected to the strip hole 38.

[0039] In this embodiment, the mounting bracket 33 can maintain its stability during the up-and-down movement, avoiding the situation where the mounting bracket 33 deviates when moving down, which would affect the detection accuracy of the detection mechanism 4.

[0040] A slide rod 39 is fixedly installed on one side inside the mounting bracket 33. One end of the slide rod 39 passes through the mounting plate 36 and is slidably connected to the mounting plate 36.

[0041] In this embodiment, the stability of the mounting plate 36 can be maintained when it moves laterally, avoiding the situation where the mounting plate 36 rotates as the lead screw 35 rotates, which would affect the detection of the detection mechanism 4.

[0042] Example 2:

[0043] Based on Embodiment 1, this embodiment takes into account that although the electronic components can be detected by the detection mechanism 4 through Embodiment 1 alone, in actual use, dust dispersed in the working environment is easy to adhere to the surface of the detection lens, which affects the detection accuracy. Therefore, this embodiment uses the following structure to prevent and remove dust from the detection lens of the laser detector 41.

[0044] The testing mechanism 4 includes a laser detector 41 disposed inside the adjustment mechanism 3 for testing electronic components. A second electric push rod 42 is disposed on both sides of the bottom of the laser detector 41. A first housing 43 is fixedly mounted on the telescopic end of the second electric push rod 42. The first housing 43 is sleeved on the surface of the laser detector 41 and slidably connected to it. A dustproof component 44 is installed at the bottom of the first housing 43. A cleaning component 45 is installed inside the first housing 43. The dustproof component 44 includes components disposed at the bottom of the first housing 43. The second housing 441 has a rotating connector 442 connected to the bottom of the first housing 43. The rotating connector 442 passes through the second housing 441 and extends into the interior of the second housing 441. The second housing 441 and the rotating connector 442 are rotatably connected. Several first nozzles 443 are installed through the bottom of the second housing 441. An air pump 444 is installed on one side of the first housing 43. The air outlet of the air pump 444 is connected to a double-ended connecting pipe 445. One end of the double-ended connecting pipe 445 passes through the first housing 43 and extends into the interior of the first housing 43.

[0045] In this embodiment, the air pump 444 can work to inflate the interior of the first housing 43. When the gas enters the interior of the first housing 43, it is injected into the interior of the second housing 441 through the connection between the rotating connector 442 and the second housing 441. The gas is then blown onto the detection lens of the laser detector 41 through the first nozzle 443 to prevent dust from adhering to the detection lens of the laser detector 41.

[0046] A gear ring 446 is mounted on the surface of the second housing 441, and a second servo motor 447 is mounted on one side of the first housing 43. A gear 448 is fixedly mounted on the output end of the second servo motor 447, and the gear 448 and the gear ring 446 are meshed.

[0047] In this embodiment, while the first nozzle 443 blows air, the second servo motor 447 drives the gear 448 to rotate, and the meshing connection between the gear 448 and the gear ring 446 drives the second housing 441 to rotate, further improving the dustproof effect of the dustproof component 44.

[0048] The cleaning component 45 includes a third housing 451 that is installed through the first housing 43. A hollow rod 452 is hinged to one side of the third housing 451. A second nozzle 453 is connected to one side of the hollow rod 452. One end of a double-ended connecting pipe 445 passes through the first housing 43 and the third housing 451 in sequence and extends into the interior of the third housing 451. A hose 454 is connected to one end of the double-ended connecting pipe 445 inside the third housing 451. One end of the hose 454 is connected to one side of the hollow rod 452. A third electric push rod 455 is hinged to one side of the third housing 451. The telescopic end of the third electric push rod 455 is hinged to the bottom of one side of the hollow rod 452.

[0049] In this embodiment, the second electric push rod 42 pushes the first housing 43 and the dustproof component 44, causing the cleaning component 45 to move down to the bottom of the laser detector 41's detection lens. At the same time, the third electric push rod 455 pushes the hollow rod 452, making the hollow rod 452 parallel to the laser detector 41's detection lens. The double-ended connecting pipe 445 and the flexible hose 454 cause the second nozzle 453 to spray air. As the second housing 441 rotates, it drives the hollow rod 452 to spray air at the laser detector 41's detection lens, thereby cleaning the laser detector 41's detection lens with air.

[0050] Working principle: When the laser detector 41 is inspecting electronic components, the air pump 444 can work to inflate the inside of the first housing 43. When the gas enters the inside of the first housing 43, it is injected into the inside of the second housing 441 through the connection between the rotating connector 442 and the second housing 441. The gas is then blown onto the detection lens of the laser detector 41 through the first nozzle 443. At the same time as the first nozzle 443 blows air, the second servo motor 447 works to drive the gear 448 to rotate. The meshing connection between the gear 448 and the gear ring 446 drives the second housing 441 to rotate, further improving the dustproof effect of the dustproof component 44.

[0051] After the laser detector 41 has been in use for a period of time, the second electric push rod 42 pushes the first housing 43 and the dustproof component 44, causing the cleaning component 45 to move down to the bottom of the laser detector 41's detection lens. At the same time, the third electric push rod 455 pushes the hollow rod 452, making the hollow rod 452 parallel to the laser detector 41's detection lens. The double-headed connecting pipe 445 and the hose 454 cause the second nozzle 453 to spray air. As the second housing 441 rotates, it drives the hollow rod 452 to spray air at the laser detector 41's detection lens, thus cleaning the laser detector 41's detection lens.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
