Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, specifically to an AOI (Optical Inspection Institute) device. Background Technology

[0002] AOI equipment is an automated device that uses optical imaging and image processing technology to perform non-contact inspection of surface defects, soldering quality, and component positions of products such as electronic components and printed circuit boards (PCBs).

[0003] When existing AOI equipment inspects products, the positions of the product and the inspection components are relatively fixed. This may result in blind spots during the inspection process, reducing inspection accuracy. In addition, most of the inspection components are located on top of the product, and the bottom of the product cannot be effectively inspected. This makes it impossible to conduct a comprehensive inspection of the product, further reducing the inspection accuracy and affecting the reliability of subsequent product use.

[0004] Therefore, there is a need to provide an AOI inspection device designed to solve the above problems. Summary of the Invention

[0022] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0023] 1. In this invention, the opening and closing components enable the side opening and closing, facilitating the import and export of products. Simultaneously, they prevent the environment from being affected by external factors. The placement component provides stable support and positioning for the test piece. The moving component, by moving the placement component, synchronously moves the test piece, allowing for position adjustment. The detection component enables comprehensive and efficient testing of the test piece, avoiding blind spots that might occur due to the fixed relative positions of the test piece and the detection component, thus improving detection accuracy and effectiveness. The controller allows operators to control the start and stop of the electrical equipment within the device, achieving intelligent testing of the test piece.

[0024] 2. In this invention, the motor drives the rotating gear to rotate. The rotating gear drives the two rotating rings to rotate by meshing with the toothed ring and by rotating the rotating ring and the placement frame. The rotating ring drives the workpiece to move synchronously by driving the support to move synchronously. This can realize the rotation of the workpiece. When the supplementary light ring is powered on, it can provide supplementary lighting to the surface of the workpiece. The detector one, by cooperating with the detector two and by rotating the workpiece to rotate, can perform comprehensive and efficient detection on the upper and lower sides of the workpiece. This can effectively reduce the problem of blind spots that may occur when the workpiece and the detector one and detector two are relatively fixed in position, and improve the detection accuracy and detection effect.

[0025] 3. In this invention, when it is necessary to open two side openings, motor one drives pulley two and drive gear to rotate in the forward direction. Pulley two pushes lifting plate two upward by meshing with driven gear, transmission gear two meshing with fixed rack two, and lifting plate two slidingly engaging with the inner wall of the outer shell, thereby opening the side opening corresponding to one side of lifting plate two. At the same time, drive gear drives pulley one to rotate synchronously by connecting with transmission belt. Pulley one drives lifting plate one to move upward by meshing with transmission gear one and fixed rack one, and lifting plate one slidingly engaging with the inner wall of the outer shell, thereby opening the side opening corresponding to one side of lifting plate one. Thus, the synchronous opening of two side openings can be achieved.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0046] In one embodiment of the present invention, see Figures 1-2 An AOI (Automated Optical Inspection) device includes a housing 1, a support plate 106 installed inside the housing 1, side openings 102 symmetrically opened on both sides of the housing 1, a controller 104 electrically connected to the electrical equipment inside the device on the housing 1, an opening and closing component 2 corresponding to the side openings 102 inside the housing 1, placement components 4 symmetrically arranged above the support plate 106 for placing the workpiece 7 to be inspected, a moving component 3 connected to the two placement components 4 on the support plate 106, a lifting component 5 between the support plate 106 and the placement components 4, and a detection component 6 located above the placement components 4 inside the housing 1.

[0047] In this embodiment, the opening and closing component 2 enables the side opening 102 to be opened and closed, facilitating the import and export of products and preventing the environment from being affected by external factors. Simultaneously, the placement component 4 provides stable support and positioning for the part to be tested 7. The moving component 3 moves the part to be tested 7 synchronously by moving the placement component 4, enabling position adjustment. The detection component 6 allows for comprehensive and efficient detection of the part to be tested 7, avoiding blind spots that might occur due to the fixed relative positions of the part to be tested 7 and the detection component 6 during the detection process, thus improving detection accuracy and effectiveness. The controller 104 allows operators to control the start and stop of the electrical equipment within the device, enabling intelligent detection of the part to be tested 7. This system offers advantages such as flexible opening and closing, stable support, convenient movement, comprehensive and efficient detection, high detection accuracy, intelligent control, reliable structure, and ease of use.

[0048] The outer shell 1 has a symmetrically hinged door 101 in the middle, which corresponds to the support plate 106. The outer shell 1 also has a symmetrically hinged door 105 located below the support plate 106. The top of the outer shell 1 is provided with a signal light 103 that is electrically connected to the controller 104. This light can send a signal when a fault occurs during the intelligent detection of the test piece 7, so that the staff can repair it in time.

[0049] In one embodiment of the present invention, see Figures 1-4The opening and closing assembly 2 includes a lifting plate 201 slidably disposed on the inner wall of one side of the outer casing 1 and a lifting plate 207 slidably disposed on the inner wall of the other side of the outer casing 1. The lifting plate 201 is provided with a fixed rack 202, and the lifting plate 207 is provided with a fixed rack 208. A rotating rod 204 is rotatably disposed on the inner wall of one side of the outer casing 1. One end of the rotating rod 204 is connected to a transmission gear 203 that meshes with the fixed rack 202, and the other end of the rotating rod 204 is connected to a pulley 205. A rotating rod 210 is rotatably mounted on the inner wall of the other side of the shell 1. One end of the rotating rod 210 is connected to a transmission gear 209 that meshes with a fixed rack 208. The other end of the rotating rod 210 is connected to a driven gear 211. A motor 214 is installed inside the shell 1. A driving gear 212 and a pulley 213 are connected to the output shaft of the motor 214. The driving gear 212 meshes with the driven gear 211. The pulley 213 and the pulley 205 are connected by a transmission belt 206.

[0050] In this embodiment, in the initial state, the bottoms of both the first lifting plate 201 and the second lifting plate 207 are in contact with the upper surface of the support plate 106 to be tested 7. At this time, the inside of the outer shell 1 is in a closed state, which facilitates the normal testing of the component to be tested 7.

[0051] When it is necessary to open both side openings 102, the motor 214 drives the pulley 213 and the drive gear 212 to rotate in the forward direction. The pulley 213 pushes the lifting plate 207 upward by meshing with the driven gear 211, the transmission gear 209 and the fixed rack 208, and the lifting plate 207 slidingly engaging with the inner wall of the outer shell 1, thereby opening the side opening 102 corresponding to one side of the lifting plate 207. At the same time, the drive gear 212 drives the pulley 205 to rotate synchronously by connecting with the transmission belt 206. The pulley 205 drives the lifting plate 201 to move upward by meshing with the transmission gear 203 and the fixed rack 202, and the lifting plate 201 slidingly engaging with the inner wall of the outer shell 1, thereby opening the side opening 102 corresponding to one side of the lifting plate 201. Thus, the synchronous opening of both side openings 102 can be achieved.

[0052] When it is necessary to close both side openings 102, the motor 214 drives the pulley 213 and the drive gear 212 to rotate in opposite directions. The pulley 213 pushes the lifting plate 207 downward by meshing with the driven gear 211, the transmission gear 209 and the fixed rack 208, and the lifting plate 207 slidingly engaging with the inner wall of the outer shell 1, thereby closing the side opening 102 corresponding to the side of the lifting plate 207. At the same time, the drive gear 212 drives the pulley 205 to rotate synchronously by connecting with the transmission belt 206. The pulley 205 drives the lifting plate 201 to move downward by meshing with the transmission gear 203 and the fixed rack 202, and the lifting plate 201 slidingly engaging with the inner wall of the outer shell 1, thereby closing the side opening 102 corresponding to the side of the lifting plate 201. Thus, the synchronous closing of the two side openings 102 can be achieved.

[0053] Among them, the fixed rack 1 202 and the fixed rack 208 have the same size, the transmission gear 1 203 and the transmission gear 209 have the same size, the pulley 1 205 and the pulley 213 have the same size, and the driven gear 211 and the driving gear 212 have the same size, which can ensure that the lifting plate 1 201 and the lifting plate 207 can move up or down synchronously.

[0054] In addition, in actual operation, the corresponding dimensions can be adjusted according to the actual opening and closing requirements to meet the different speeds of the lifting plate 201 and the lifting plate 207 moving up and down.

[0055] In one embodiment of the present invention, see Figures 1-2 , Figures 6-10 The placement assembly 4 includes a placement frame 401 movably disposed above the support plate 106. A rotating ring 402 is rotatably disposed on the placement frame 401. Several brackets 403 for supporting the test piece 7 are distributed circumferentially on the upper part of the rotating ring 402. Several brackets 403 are distributed circumferentially on the rotating ring 402. The tops of the brackets 403 are connected by a top ring 407. A lifting ring 405 is slidably disposed on the brackets 403. Several brackets 406 corresponding to the brackets 403 are distributed circumferentially on the bottom of the lifting ring 405. An electric cylinder 408 is connected between the top ring 407 and the lifting ring 405.

[0056] The movable component 3 includes upright plates 301 symmetrically arranged at the bottom of the support plate 106. Screws 303 are rotatably connected between the symmetrically arranged upright plates 301. One end of the screw 303 is connected to a motor 302 mounted on the upright plate 301. Two sets of guide rails 309 are symmetrically arranged on the support plate 106. A sliding frame 310 is slidably arranged on the guide rails 309. An upright 307 connected to the bottom of the corresponding placement frame 401 is slidably arranged through the sliding frame 310. Several slots 308 are opened on the support plate 106 to movably cooperate with the upright 307. The ends of the several uprights 307 away from the placement frame 401 are connected by a lifting frame 306. A limiting slide plate 305 is symmetrically arranged on the side of the lifting frame 306 away from the support plate 106. A threaded plate 304 is threadedly connected to the screw 303 to slide in cooperation with the two limiting slide plates 305.

[0057] In this embodiment, in the initial state, the placement frame 401 and the threaded plate 304 are located at one end of the sliding frame 310, the lifting ring 405 is at the highest point, and the electric cylinder 408 is at its original length. The test piece 7 is placed on several supports 403 by a robotic arm or a handling module (not shown in the figure). The electric cylinder 408 extends downward and pushes the lifting ring 405 down along the column 404. The column 404 drives the support 406 to move down synchronously. The support 406 positions the upper and lower sides of the test piece 7 by cooperating with the support 403, so as to facilitate the synchronous movement of the test piece 7.

[0058] Motor 302 drives screw 303 to rotate in the forward direction. Screw 303 drives screw plate 304 to move to the other end of sliding frame 310 through threaded connection with screw plate 304 and sliding engagement between screw plate 304 and limiting slide plate 305. Screw plate 304 drives placement frame 401 to move synchronously through sliding engagement with limiting slide plate 305, connection between lifting frame 306 and upright 307, movable engagement between upright 307 and slot 308, and connection between upright 307 and placement frame 401. At the same time, upright 307 drives sliding frame 310 to move synchronously through sliding engagement with sliding frame 310, so that placement frame 401 is always above sliding frame 310. Placement frame 401 drives rotating ring 402 to move synchronously, thereby enabling adjustment of the position of the part to be tested 7.

[0059] The guide rails 309 are provided in at least four parts. The brackets 403 and 406 are both set as tripods, which facilitates stable support of the corners of the part to be tested 7. At the same time, the support area is reduced, which facilitates comprehensive testing of the part to be tested 7 and improves the testing range and testing effect.

[0060] In one embodiment of the present invention, see Figures 1-2 , Figures 8-9 The lifting component 5 includes several guide plates 501 disposed on the support plate 106, and the two ends of the placement frame 401 are respectively provided with rollers 502 that are rotatably in contact with the upper edge of the guide plates 501.

[0061] In this embodiment, in the initial state, the roller 502 is in contact with the lower part of one end of the guide plate 501. The motor 302 drives the screw 303 to rotate in the forward direction. The screw 303 drives the threaded plate 304 to move to the other end of the sliding frame 310 by means of threaded connection with the threaded plate 304 and sliding engagement between the threaded plate 304 and the limiting slide plate 305. The threaded plate 304 drives the placement frame 401 to move synchronously by means of sliding engagement with the limiting slide plate 305, connection between the lifting frame 306 and the upright 307, movable engagement between the upright 307 and the slot 308, and connection between the upright 307 and the placement frame 401. At the same time, the upright 307 drives the sliding frame 310 to move synchronously by means of sliding engagement with the sliding frame 310, so that the placement frame 401 is always above the sliding frame 310. The placement frame 401 drives the test piece 7 to move synchronously by means of driving the rotating ring 402 to move synchronously.

[0062] During the movement of the placement frame 401 and the rotating ring 402, the roller 502 moves along the upper edge of the guide plate 501 towards the middle of the guide plate 501. Since the guide plate 501 is an isosceles trapezoid, the roller 502 pushes the placement frame 401 upward by contacting the guide plate 501. The placement frame 401 drives the rotating ring 402 upward synchronously. The rotating ring 402 drives the workpiece 7 to be tested to be moved upward synchronously by driving the support 403 upward. This can achieve the height increase of the workpiece 7 to be tested, which is convenient for comprehensive inspection of the bottom of the workpiece 7.

[0063] After the placement frame 401 moves past the middle of the guide rail 309, the roller 502 at the front end of the placement frame 401 stops contacting the guide plate 501, while the roller 502 at the rear end of the placement frame 401 contacts the guide plate 501. As the placement frame 401 continues to move, the roller 502 drives the placement component 4 to move downward by contacting the guide plate 501 and by the gravity of the placement component 4 itself, which can realize the lowering of the height of the test piece 7, thereby realizing the height adjustment of the test piece 7.

[0064] The length of the middle part of the guide plate 501 is not less than the distance between the front roller 502 and the rear roller 502 of the placement frame 401.

[0065] In one embodiment of the present invention, see Figures 1-2 , Figures 6-9The detection component 6 includes a fixing frame 601 mounted on the inner wall of the outer casing 1, the fixing frame 601 being located above the placement component 4, the fixing frame 601 having symmetrically arranged side plates 602 in the middle, the two sides of the side plates 602 being connected to the connecting ring frame 603 via connecting plates 606, the bottom of the connecting ring frame 603 having a supplementary light ring 604, the bottom of the side plates 602 having a detector 605 located inside the connecting ring frame 603, the side wall of the rotating ring 402 having a toothed ring 607, an electric cylinder 408 connecting the two placement frames 401, the electric cylinder 408 having a motor 610 mounted on it, the output shaft of the motor 610 being connected to a rotating gear 609 meshing with the two toothed rings 607, the bottom of the rotating gear 609 having a laser sensor, the middle of the support plate 106 having a laser emitter 611 corresponding to the movement of the laser sensor, and a detector 612 being mounted at the upper center of the placement frame 401.

[0066] In this embodiment, initially, the placement frame 401 corresponds to one end of the guide rail 309, and the component to be tested 7 is placed on the placement assembly 4. The moving assembly 3 drives the component to be tested 7 to move synchronously by moving the placement assembly 4 to the other end of the guide rail 309. When the placement assembly 4 moves to the middle of the guide rail 309, the placement assembly 4 is at its highest point, that is, the component to be tested 7 is at its highest point, and the distance between the component to be tested 7 and the detector 612 reaches its maximum value. The laser sensor moves to directly above the laser emitter 611, receives the signal, and transmits the data to the controller 104. The controller 104 controls the motor 610 to work and controls the motor 302 to stop working. At this time, the component to be tested 7 stops moving, and the motor 610 drives the rotating gear. Rotating gear 609, through meshing with toothed ring 607 and the rotational cooperation of rotating ring 402 and placement bracket 401, drives two rotating rings 402 to rotate. The rotating rings 402 drive the synchronous movement of bracket 1 403, thereby enabling the rotation of the workpiece 7. When the supplementary light ring 604 is powered on, it can provide supplementary lighting to the surface of the workpiece 7. Detector 1 605, through cooperation with detector 2 612 and the rotation of the workpiece 7 driven by rotating ring 402, can perform comprehensive and efficient detection on the upper and lower sides of the workpiece 7. This effectively reduces the problem of blind spots that may occur when the workpiece 7 is relatively fixed in position with detector 1 605 and detector 2 612, thus improving detection accuracy and effect.

[0067] After the test is completed, the controller 104 controls the motor 610 to stop working and controls the motor 302 to continue working, which can realize the continued adjustment of the position of the test piece 7. When the placement rack 401 corresponds to the other end of the guide rail 309, the electric cylinder 408 retracts upward and drives the lifting ring 405 to move upward. The lifting ring 405 releases the restriction on the top of the test piece 7 by driving the bracket 406 to move upward synchronously, which facilitates the removal of the test piece 7.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
