Description

Technical Field

[0001] The present invention relates to the technical field of X-ray detection, and in particular to a product internal defect detection device based on an X-ray imaging analysis system. Background Art

[0002] During the manufacturing process of products, such as the manufacturing of 3C products (a collective term for computer, communication, and consumer electronic products), various factors in each process may cause defects such as scratches, pits, and bubbles on the products. Therefore, it is necessary to perform corresponding inspections on the products to ensure product quality.

[0003] The existing detection methods usually use machine vision detection to collect images of products, and then use algorithms to analyze the images and measure defects, which can achieve non-contact long-term online defect detection. However, the machine vision detection method can only detect surface defects of products and cannot detect internal defects of products. In addition, the machine vision detection method can only identify one side surface of the product, and the product needs to be turned over to identify the other side surface. During the turning process, it is easy to cause deviation in the placement position of the product, resulting in inaccurate defect detection results for the product. Summary of the Invention

[0004] In order to achieve the detection of internal defects of products and improve the detection accuracy of internal and surface defects of products, the present application provides a product internal defect detection device based on an X-ray imaging analysis system.

[0005] The present application provides a product internal defect detection device based on an X-ray imaging analysis system, adopting the following technical solutions: A product internal defect detection device based on an X-ray imaging analysis system includes a detection chassis. A detection platform and a rotary feeding component for conveying the product above the detection platform are arranged in the detection chassis. An X-ray generating device is arranged below the detection platform in the detection chassis, and an X-ray detector is arranged above the detection platform in the detection chassis. A horizontal adjustment mechanism and a vertical adjustment component acting on the X-ray generating device and the X-ray detector are arranged in the detection chassis, and the vertical adjustment component is arranged on the horizontal adjustment mechanism.

[0006] By adopting the above technical solution, the rotating feeding component helps to sequentially convey multiple products above the detection platform; the X-ray generating device helps to emit an X-ray beam with uniform intensity and penetrate the products, and the X-ray detector helps to receive the X-ray beam that penetrates the products, thereby helping to detect whether there is a change in the intensity of the X-ray beam, and further helping to detect the defects inside and on the surface of the products, and at the same time helping to improve the detection accuracy of detecting the defects inside and on the surface of the products. The horizontal adjustment mechanism helps to adjust the positions of the X-ray generating device and the X-ray detector in the horizontal direction at the same time, and the two sets of vertical adjustment components help to adjust the positions of the X-ray generating device and the X-ray detector in the vertical direction respectively, thereby helping to further improve the detection accuracy of detecting the defects inside and on the surface of the products.

[0007] In a specific feasible implementation, the rotating feeding component includes a rotating motor, a rotating shaft, a connecting seat, and a plurality of material placing plates. The rotating motor is arranged on the top wall of the detection chassis, the rotating shaft is coaxially arranged on the output shaft of the rotating motor, the connecting seat is sleeved on the rotating shaft, and the plurality of material placing plates are arranged at intervals on the outer periphery of the connecting seat. Each material placing plate is provided with a material placing groove.

[0008] By adopting the above technical solution, the rotating motor helps to drive the rotating shaft to rotate intermittently, thereby helping to drive the connecting seat and the plurality of material placing plates to rotate intermittently, and further helping to move the plurality of material placing plates above the detection platform in sequence, facilitating the detection of defects of the products placed in the material placing grooves.

[0009] In a specific feasible implementation, a clamping track is axially arranged on the circumferential side wall of the rotating shaft, a clamping block that is clamped into the clamping track is arranged on the connecting seat, a fixed baffle is arranged at one end of the rotating shaft away from the rotating motor, a top support spring is arranged on the fixed baffle, the top support spring is sleeved on the rotating shaft, and one end of the top support spring away from the fixed baffle is connected to the connecting seat. A pressing component for making the material placing plate fit and place on the detection platform is arranged on the rotating shaft, and a positioning detection component is jointly arranged on the detection platform and the material placing plate.

[0010] By adopting the above technical solution, the use of the clamping block in cooperation with the clamping track helps to limit the rotation of the connecting seat on the rotating shaft; the use of the pressing assembly helps to press the connecting seat, thereby helping to drive the feeding plate to move downward until it fits against the top surface of the detection platform; the use of the alignment detection assembly helps to detect the position of the feeding plate on the detection platform, thereby helping to improve the accuracy of the position where the feeding plate is placed in contact with the detection platform, and further helping to improve the detection accuracy of detecting defects inside and on the surface of the product. The use of the top support spring helps to support the connecting seat, thereby helping to drive the connecting seat and several feeding plates to reset.

[0011] In a specific feasible implementation, the pressing assembly includes a movable sleeve, a pressing frame, a return spring, and a fixed insertion rod. The pressing frame is sleeved on the rotating shaft. The pressing frame is located above the connecting seat and abuts against the connecting seat. A fixed plate is fixedly sleeved on the rotating shaft inside the pressing frame. The return spring is sleeved on the rotating shaft. The bottom end of the return spring is connected to the fixed plate, and the top end of the return spring is connected to the pressing frame. The movable sleeve is sleeved on the rotating shaft and abuts against the top of the pressing frame. A sliding track is axially arranged on the circumferential side wall of the rotating shaft. A slider that is inserted into the sliding track is arranged on the circumferential inner wall of the movable sleeve. Several groups of interconnected guiding tracks are arranged on the circumferential outer wall of the movable sleeve. The fixed insertion rod is arranged on the inner wall of the detection chassis, and the end of the fixed insertion rod is inserted into the guiding track.

[0012] By adopting the above technical solution, while the rotating shaft rotates, the cooperation of the slider and the sliding track helps to make the movable sleeve rotate synchronously. At the same time, under the combined action of the fixed insertion rod and the guiding track, it helps to make the movable sleeve move downward while rotating, thereby helping to drive the pressing frame to press the connecting seat, and further helping to drive the feeding plate to move downward until it fits against the top surface of the detection platform.

[0013] In a specific feasible implementation, each group of the guiding tracks includes an arc track, a horizontal track, and a vertical track. The arc track, the horizontal track, and the vertical track are all arranged on the circumferential outer wall of the movable sleeve. The horizontal track is fixedly connected to the top end of the arc track. The top end of the vertical track is connected to the end of the horizontal track away from the arc track. The bottom end of the vertical track is connected to the bottom end of another arc track.

[0014] By adopting the above technical solution, the relative movement of the fixed insertion rod in the arc-shaped track helps drive the movable sleeve to move vertically while rotating; the relative movement of the fixed insertion rod in the horizontal track helps keep the movable sleeve stationary in the vertical direction while rotating; the elastic force of the return spring helps make the fixed insertion rod move downward relatively in the vertical track, thereby helping the movable sleeve to reset.

[0015] In a specific feasible implementation, the alignment detection component includes a pressure sensor and an alignment insertion rod. There are mounting blind holes provided on the detection platform. The pressure sensor is arranged in the mounting blind holes. The alignment insertion rod is arranged on the surface of the material placing plate facing the detection platform. A conical inclined surface for guiding the alignment insertion rod to insert is arranged at the opening of the mounting blind hole.

[0016] By adopting the above technical solution, the insertion of the alignment insertion rod into the mounting blind hole helps press against the pressure sensor, thereby helping to indirectly detect the position of the material placing plate on the detection platform by using the pressure sensor, and further helping to improve the accuracy of the position where the material placing plate is placed in a fitting manner on the detection platform, and helping to further improve the detection accuracy of detecting defects inside and on the surface of the product. The conical inclined surface helps guide the alignment insertion rod into the interior of the mounting blind hole.

[0017] In a specific feasible implementation, a positioning magnet is arranged at one end of the clamping track far away from the fixed baffle, and the clamping block is made of a magnetic adsorption material.

[0018] By adopting the above technical solution, the positioning magnet helps adsorb and fix the clamping block, thereby helping to position the connecting seat on the rotating shaft, and further helping to improve the stability during the process of the material placing plate driving the product to move.

[0019] In a specific feasible implementation, the horizontal adjustment mechanism includes two fixed frames respectively arranged on the inner top and inner bottom of the detection chassis. An active block is slidably clamped in each fixed frame. There are two groups of vertical adjustment components, and each group of vertical adjustment components is arranged on an active block. The horizontal adjustment mechanism further includes a driving component for driving the active block to slide inside the fixed frame.

[0020] By adopting the above technical solution, the driving component helps drive two active blocks to slide inside the fixed frames simultaneously, thereby helping to adjust the positions of the X-ray generating device and the X-ray detector in the horizontal direction simultaneously through the two groups of vertical adjustment components, helping to keep the X-ray generating device and the X-ray detector always aligned, and further helping to improve the detection accuracy of detecting defects inside and on the surface of the product.

[0021] In a specific feasible implementation, the driving assembly includes a double-headed motor, a connecting rod, a threaded rod, a first bevel gear, and a second bevel gear. The double-headed motor is arranged on the inner side wall of the detection chassis. The connecting rod is coaxially arranged on the output shaft of the double-headed motor. The threaded rod is rotatably arranged in the fixed frame and is threadedly connected to the movable block. The first bevel gear is sleeved on the connecting rod, the second bevel gear is sleeved on the threaded rod, and the first bevel gear meshes with the second bevel gear.

[0022] By adopting the above technical solution, the double-headed motor helps to drive the two connecting rods to rotate simultaneously. The first bevel gear and the second bevel gear help to drive the two threaded rods to rotate synchronously while the connecting rods rotate, thereby helping to drive the two movable blocks to slide in the fixed frame, helping to adjust the positions of the X-ray generating device and the X-ray detector in the horizontal direction simultaneously through the two sets of vertical adjustment components, helping to keep the X-ray generating device and the X-ray detector always aligned, and further improving the detection accuracy of defect detection for the interior and surface of the product.

[0023] In a specific feasible implementation, each set of the vertical adjustment components includes an electric slide table and a slide seat. The electric slide table is vertically arranged on the side wall of the movable block, and the slide seat is slidably arranged on the electric slide table.

[0024] By adopting the above technical solution, the electric slide table helps to drive the slide seat to move in the vertical direction, thereby helping to drive the X-ray generating device or the X-ray detector to move in the vertical direction, helping to adjust the distance between the X-ray generating device or the X-ray detector and the product, thereby helping to improve the defect detection effect for the interior and surface of the product, and further helping to improve the detection accuracy of defect detection for the interior and surface of the product.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the rotary feeding assembly, the X-ray generating device, and the X-ray detector, the rotary feeding assembly helps to sequentially convey a plurality of products above the detection platform.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] An embodiment of the present application discloses a product internal defect detection device based on an X-ray imaging analysis system.

A clamping track 6 is axially formed on the circumferential side wall of the rotary shaft 32. A clamping block 7 is integrally formed on the connecting seat 33, and the clamping block 7 is slidably clamped inside the clamping track 6. A positioning magnet 18 is fixed at the top end of the clamping track 6, and in this embodiment, the clamping block 7 is made of magnetic material. The bottom end of the rotary shaft 32 is provided with a fixed baffle 8. A top support spring 9 sleeved on the outer periphery of the rotary shaft 32 is installed on the fixed baffle 8, and the top end of the top support spring 9 is fixedly connected to the bottom surface of the connecting seat 33. The three feeding plates 34 are installed at intervals on the circumferential side wall of the connecting seat 33, and a feeding groove 341 is formed on the top surface of each feeding plate 34.

[0035] Referring to Figure 1 and Figure 4, a pressing component 10 is arranged above the connecting seat 33 on the rotary shaft 32. The pressing component 10 includes a movable sleeve 101, a pressing frame 102, a return spring 103 and a fixed plug 104. The pressing frame 102 is sleeved on the circumference of the rotary shaft 32 in a liftable manner. The pressing frame 102 is located above the connecting seat 33 and abuts against the connecting seat 33. A fixing plate 11 is fixedly sleeved on the rotary shaft 32 inside the pressing frame 102. The return spring 103 is sleeved on the rotary shaft 32, and the bottom end of the return spring 103 is fixedly connected to the top surface of the fixing plate 11. The top end of the return spring 103 is fixedly connected to the inner top wall of the pressing frame 102. The movable sleeve 101 is slidably sleeved on the circumference of the rotary shaft 32. The sliding sleeve is located above the pressing frame 102 and abuts against the pressing frame 102. A sliding track 12 is axially formed on the circumferential side wall of the rotary shaft 32. A slider 13 is integrally formed on the circumferential inner wall of the movable sleeve 101, and the slider 13 is slidably clamped in the sliding track 12. Three groups of mutually connected guiding tracks 14 are formed on the circumferential side wall of the movable sleeve 101. The fixed plug 104 is installed on the inner side wall of the detection chassis 1, and one end of the fixed plug 104 is inserted into the guiding track 14.

[0036] Referring to Figure 1 and Figure 4, each set of guiding tracks 14 includes an arc track 141, a horizontal track 142, and a vertical track 143. The arc track 141, the horizontal track 142, and the vertical track 143 are sequentially formed on the circumferential side wall of the movable sleeve 101. The horizontal track 142 is horizontally formed on the top side wall of the movable sleeve 101. The top end of the arc track 141 is fixedly communicated with one end of the horizontal track 142. The bottom end of the arc track 141 is fixedly communicated with the bottom end of the vertical track 143 in the second set of guiding tracks 14. The top end of the vertical track 143 is fixedly communicated with the other end of the horizontal track 142. The bottom end of the vertical track 143 is fixedly communicated with the bottom end of the arc track 141 in the third set of guiding tracks 14. In the initial state, the fixed plug 104 is inserted at the bottom position of one of the vertical tracks 143.

[0037] Refer to Figure 2 and Figure 3 , during the process of defect detection of the product, the product is placed into the feeding groove 341 on the feeding plate 34 by the manipulator. After the feeding is completed, the rotating motor 31 runs intermittently, driving the rotating shaft 32 to rotate intermittently, so as to drive the connecting seat 33 and the three feeding plates 34 to rotate synchronously under the limiting action of the clamping block 7. Furthermore, after each rotation of the rotating shaft 32, one of the feeding plates 34 will rotate to the position directly above the detection platform 2.

[0038] Refer to Figure 2 and Figure 4 , during each rotation of the rotating shaft 32, the movable sleeve 101 is driven to rotate synchronously under the limiting action of the slider 13, so that the fixed plug 104 relatively moves from the bottom of the arc track 141 to the top of the arc track 141, causing the movable sleeve 101 to move downward while rotating under the limiting and guiding actions of the slider 13, thereby pressing the connecting seat 33 through the pressing frame 102, and further driving the feeding plate 34 to move downward while rotating. When the feeding plate 34 moves to the position directly above the detection platform 2, the feeding plate 34 will simultaneously move downward to a position where it fits against the top surface of the detection platform 2. At the same time, the fixed plug 104 relatively moves into the horizontal track 142, so that the movable sleeve 101 remains stationary in the vertical direction, and further enables the positions of the pressing frame 102, the connecting seat 33, and the feeding plate 34 to remain stable in the vertical direction, which helps the feeding plate 34 to stably fit on the top surface of the detection platform 2.

[0039] Refer to Figure 2 and Figure 5, a plurality of alignment detection components 15 are jointly arranged on the detection platform 2 and the material placing plate 34. Each group of alignment detection components 15 includes a pressure sensor 151 and an alignment insertion rod 152. Installation blind holes 16 are formed at the four corner positions on the top surface of the detection platform 2. The pressure sensor 151 is fixedly installed on the inner bottom wall of the installation blind hole 16, and a conical inclined surface 17 is formed at the top opening of the installation blind hole 16. The alignment insertion rod 152 is fixedly installed at the four corner positions on the bottom surface of the material placing plate 34.

[0040] Refer to Figure 2 and Figure 5 , during the process that the material placing plate 34 gradually moves to directly above the detection platform 2 and moves downward to a position where it fits against the top surface of the detection platform 2, the alignment insertion rod 152 will gradually be inserted into the installation blind hole 16 under the drive of the material placing plate 34; when the material placing plate 34 is placed and fitted on the top surface of the detection platform 2, the alignment insertion rod 152 will press against the pressure sensor 151, so that the pressure sensor 151 detects a pressure signal, which helps to indirectly detect whether the position of the material placing plate 34 placed on the detection platform 2 is accurate through the pressure sensor 151, and helps to improve the accuracy of subsequent defect detection of the product. The setting of the conical inclined surface 17 helps to guide the alignment insertion rod 152 to insert into the installation blind hole 16.

[0041] Refer to Figure 2 , a horizontal adjustment mechanism is arranged inside the detection chassis 1. The horizontal adjustment mechanism includes two horizontally arranged fixed frames 19 respectively fixedly installed on the inner side walls of the top and bottom of the detection chassis 1. An active block 20 is slidably clamped inside each fixed frame 19. The horizontal adjustment mechanism further includes a driving component 21. The driving component 21 includes a double-headed motor 211, a connecting rod 212, a threaded rod 213, a first bevel gear 214 and a second bevel gear 215. In this embodiment, the number of the connecting rod 212, the threaded rod 213, the first bevel gear 214 and the second bevel gear 215 is two. The double-headed motor 211 is fixedly installed on the inner side wall of the detection chassis 1, and the output shaft of the double-headed motor 211 is arranged in the vertical direction. Each connecting rod 212 is coaxially fixedly connected to an output shaft of the double-headed motor 211. Each threaded rod 213 is rotatably installed inside a fixed frame 19. The threaded rod 213 penetrates through the active block 20 and is threadedly connected to the active block 20. The first bevel gear 214 is fixedly sleeved on the end of the connecting rod 212 far from the double-headed motor 211. One end of the threaded rod 213 close to the connecting rod 212 extends out of the fixed frame 19. The second bevel gear 215 is fixedly sleeved on the end of the threaded rod 213 extending out of the fixed frame 19, and the first bevel gear 214 meshes with the second bevel gear 215.

[0042] Refer to Figure 2, a vertical adjustment component 22 is provided on each movable block 20. Each group of vertical adjustment components 22 includes an electric slide table 221 and a slide seat 222. The electric slide table 221 is vertically and fixedly installed on the side wall of the movable block 20, and the slide seat 222 is slidably installed on the electric slide table 221. An X-ray generating device 4 is connected and installed on the lower slide seat 222, and an X-ray detector 5 is connected and installed on the upper slide seat 222. The X-ray generating device 4 and the X-ray detector 5 are located on both sides of the detection platform 2.

[0043] Referring to Figure 2 , after the feeding plate 34 is placed on the detection platform 2, start the X-ray generating device 4, so that the X-ray generating device 4 emits an X-ray beam with uniform intensity upward and penetrates the product placed on the feeding plate 34. At the same time, the X-ray detector 5 receives and processes the X-ray beam penetrating the product, which helps to detect whether the intensity of the X-ray beam penetrating the product changes, and further helps to detect the defects inside and on the surface of the product, and also helps to improve the detection accuracy of detecting the defects inside and on the surface of the product.

[0044] Referring to Figure 2 , when the positions of the X-ray generating device 4 and the X-ray detector 5 need to be adjusted, start the double-headed motor 211 to drive the two connecting rods 212 to rotate synchronously. Thus, under the transmission of the first bevel gear 214 and the second bevel gear 215, drive the two threaded rods 213 to rotate synchronously. Furthermore, it helps to make the two movable blocks 20 move synchronously in the horizontal direction under the limiting action of the fixed frame 19, helps to drive the X-ray generating device 4 and the X-ray detector 5 to move synchronously in the horizontal direction, and helps to keep the X-ray generating device 4 and the X-ray detector 5 always aligned, improving the detection accuracy of detecting the defects inside and on the surface of the product. At the same time, the electric slide table 221 makes the slide seat 222 move in the vertical direction, thereby driving the X-ray generating device 4 or the X-ray detector 5 to move in the vertical direction, which helps to adjust the distance between the X-ray generating device 4 or the X-ray detector 5 and the product, thus helping to improve the defect detection effect of the product inside and on the surface, and further helping to further improve the detection accuracy of detecting the defects inside and on the surface of the product.

[0045] Referring to Figure 2 and Figure 4When the product on a feeding plate 34 has completed defect detection, the rotating motor 31 drives the rotating shaft 32 to make the next rotation, causing the fixed insertion rod 104 to relatively move from within the horizontal track 142 to the top of the vertical track 143, and under the propping action of the reset spring 103 and the pressing frame 102, the movable sleeve 101 moves upward, so that the fixed insertion rod 104 relatively moves from the top of the vertical track 143 to the bottom of the vertical track 143, and further separates the feeding plate 34 from the detection platform 2, which helps the next feeding plate 34 to be placed again on the top surface of the detection platform 2 in accordance with the same steps, thus helping to perform defect detection on the product placed on the next feeding plate 34.

[0046] The implementation principle of the embodiment of the present application is as follows: During the process of defect detection of the product, the product is placed into the feeding groove 341 on the feeding plate 34 by the manipulator. After the feeding is completed, the rotating motor 31 runs intermittently, driving the rotating shaft 32 to rotate intermittently, so as to drive the connecting seat 33 and the three feeding plates 34 to rotate synchronously under the limiting action of the clamping block 7, and then each time the rotating shaft 32 rotates, a feeding plate 34 will rotate to directly above the detection platform 2.

[0047] Each time the rotating shaft 32 rotates, the movable sleeve 101 is driven to rotate synchronously under the limiting action of the slider 13, so that the fixed insertion rod 104 relatively moves from the bottom of the arc track 141 to the top of the arc track 141, and the movable sleeve 101 moves downward while rotating under the limiting and guiding action of the slider 13, so as to press the connecting seat 33 through the pressing frame 102, and then drive the feeding plate 34 to move downward while rotating. When the feeding plate 34 moves to directly above the detection platform 2, the feeding plate 34 will simultaneously move downward to a position where it fits against the top surface of the detection platform 2. At the same time, the fixed insertion rod 104 relatively moves into the horizontal track 142, so that the movable sleeve 101 remains stationary in the vertical direction, and further makes the positions of the pressing frame 102, the connecting seat 33 and the feeding plate 34 stable in the vertical direction, which helps the feeding plate 34 to be stably placed against the top surface of the detection platform 2.

[0048] During the process that the feeding plate 34 gradually moves to directly above the detection platform 2 and moves downward to a position where it fits against the top surface of the detection platform 2, the alignment insertion rod 152 will gradually be inserted into the installation blind hole 16 under the drive of the feeding plate 34; when the feeding plate 34 is placed against the top surface of the detection platform 2, the alignment insertion rod 152 will press against the pressure sensor 151, so that the pressure sensor 151 detects a pressure signal, and further helps to indirectly detect whether the position of the feeding plate 34 placed on the detection platform 2 is accurate through the pressure sensor 151, which helps to improve the accuracy of subsequent defect detection of the product.

[0049] After the feeding plate 34 is placed on the detection platform 2, the X-ray generating device 4 is started, so that the X-ray generating device 4 emits an X-ray beam with uniform intensity upward and penetrates the product placed on the feeding plate 34. At the same time, the X-ray detector 5 receives and processes the X-ray beam penetrating the product, which helps to detect whether the intensity of the X-ray beam penetrating the product changes, and further helps to detect the defects inside and on the surface of the product, and also helps to improve the detection accuracy of detecting the defects inside and on the surface of the product.

[0050] When the defect detection of the product on one feeding plate 34 is completed, the rotating motor 31 drives the rotating shaft 32 to rotate next time, so that the fixed insertion rod 104 relatively moves from the horizontal track 142 to the top of the vertical track 143, and under the top support of the return spring 103 and the pressing frame 102, the movable sleeve 101 moves upward, so that the fixed insertion rod 104 relatively moves from the top of the vertical track 143 to the bottom of the vertical track 143, and then the alignment insertion rod 152 is disengaged from the installation blind hole 16, which helps to place the next feeding plate 34 on the top surface of the detection platform 2 again according to the same steps, so as to help detect the defects of the product placed on the next feeding plate 34.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
