Description

Technical Field

[0001] The present invention belongs to the field of detection technology, and in particular relates to a detection platform of an AOI detection machine. Background Art

[0002] The core technologies of AOI inspection machines lie in optical imaging, machine vision, and image processing algorithms. Through a highly precise optical system, AOI machines capture clear images of objects to be inspected. Then, using machine vision and image processing algorithms, they automatically analyze and identify these images, enabling rapid and accurate detection of defects. This technology is applicable not only to electronics but also to other industries.

[0003] Currently, during the inspection of rectangular devices, generally only one side of the rectangular device can be inspected. After one side is inspected, the other side must be inspected. The side must be manually changed for inspection, which is not efficient and too cumbersome. Therefore, an inspection platform for an AOI inspection machine is developed. Summary of the Invention

[0004] The present invention provides an inspection platform for an AOI inspection machine, which aims to solve the problem that during the inspection of rectangular devices, generally only one side of the rectangular device can be inspected. After one side is inspected, the other side must be inspected, and the side must be manually changed for inspection, which is inefficient and too cumbersome.

[0005] An embodiment of the present invention provides an inspection platform for an AOI inspection machine, comprising a roller assembly line 1, a roller assembly line 2 installed on one side of the roller assembly line 1, and an assembly platform fixedly connected between the roller assembly line 1 and the roller assembly line 2. Inspection units are installed on both the roller assembly line 1 and the roller assembly line 2. The inspection units include an assembly rack installed on the sides of the roller assembly line 1 and the roller assembly line 2. The assembly rack is fixedly connected to a motor 2. The output end of the motor 2 is connected to one end of a threaded rod passing through the assembly rack. The other end of the threaded rod is screwed to the assembly rack. The threaded rod is threadedly connected to a displacement seat. A CCD camera is mounted on the lower side of the displacement seat. The upper wall of the displacement seat fits the assembly frame to ensure smooth movement. The position of the CCD camera can be changed to detect rectangular components.

The face-changing unit includes an assembly disc fixedly connected to the top side of the assembly table. A rotating rod is screwed to the center area of ​​the assembly disc. The end of the rotating rod farther from the assembly disc is connected to the power end of motor 1. Face-changing frames are evenly spaced on the assembly disc. Collaboration modules are mounted inside the face-changing frames for driving the displacement of the rectangular component.

[0006] The constraint unit installed in the area closer to the cooperation module inside the face-changing frame is used to constrain and lock the rectangular device.

The inner wall of the hollow rubber air cushion 1 closer to the connecting platform and away from the open part of the face changing frame is reserved with connecting ports that are passed through and evenly spaced. The end of the connecting port farther from the hollow rubber air cushion 1 extends through the connecting platform and the hollow rubber air cushion 2 in sequence to the inside of the hollow rubber air cushion 2, and a change module is installed in the area inside the connecting platform closer to the connecting port, which is used to change the opening condition of the connecting port.

[0008] Furthermore, the variable module includes an assembly cavity reserved inside the connection platform and closer to the connection port. The connection platform extends to the position of the assembly disc at an end farther from the face-changing frame and is connected to the assembly disc. The wall of the assembly cavity closer to the hollow rubber air cushion 2 is connected to the displacement platform 1 via a spring. A through-hole is reserved on the wall of the displacement platform 1 at the position adapted to the connection port. The area inside the assembly disc closer to the connection platform is reserved with the connection cavity 1. The wall of the connection cavity 1 farther from the connection platform is connected to the displacement platform 2 via a spring. The end of the displacement platform 1 farther from the hollow rubber air cushion 2 extends into the inside of the connection cavity 1 and is fixedly connected to the displacement platform 2.

[0009] Furthermore, the variable module also includes a second connection cavity which is equally spaced and reserved in the assembly disc and is closer to each connection cavity in one direction. The second connection cavity and the first connection cavity are connected to each other. The wall of the second connection cavity farther away from the first connection cavity is connected to the first magnet via a spring. The areas on the upper walls of the roller assembly line 1 and the roller assembly line 2 that are adapted to the first magnet are both connected to the second magnet. The adjacent sides of the first magnet and the second magnet repel each other.

[0010] Furthermore, the constraint unit includes displacement grooves reserved on the upper wall and the lower wall inside the face-changing frame close to the open area of ​​the face-changing frame. The outer shells are installed on both side walls of the face-changing frame. The outer shells and the displacement grooves are installed one-to-one with each other. The inside of the outer shell is connected to the displacement rod via a spring sliding. The end of the displacement rod farther from the outer shell extends to the inside of the face-changing frame through the displacement groove and is connected to the fixed platform.

[0011] Furthermore, the constraint unit also includes a connecting channel that is evenly connected to the wall of the connecting chamber 2 and is closer to the area between the magnet 1 and the magnet 2, and passes through the connecting chamber 2. The end of the connecting channel farther from the connecting chamber 2 extends to the area closer to the outer shell, and is connected to the outer shell. The connecting channel is located in the area farther from the side of the outer shell from the face-changing frame, and a temporary retention unit is installed in the area inside the assembly disc closer to the connecting channel.

[0012] Furthermore, the temporary unit includes an accommodating cavity reserved in the assembly disc and closer to the connecting channel area, and the wall of the accommodating cavity farther from the connecting channel is connected to the force applying plate via a spring sliding.

[0013] Furthermore, a plurality of rollers are arranged at equal intervals inside the roller assembly line 1 and the roller assembly line 2, and the upper walls of the rollers and the lower inner walls of the face-changing frame are in a straight line.

[0014] Furthermore, the wall of the assembly disc farther from the face-changing frame is reserved with slope 1, the area below the inner wall of the face-changing frame farther from the face-changing frame is reserved with slope 1, and the area below the inner wall of the face-changing frame farther from the face-changing frame is provided with slope 2.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention installs a face-changing unit to pull the rectangular component to perform a half-circle rotation face-changing. After the face-changing is completed, the rectangular component is automatically moved toward the direction of the second roller assembly line. The second roller assembly line transports the rectangular component that has completed the face-changing to perform double-sided inspection.

[0017] 2. The present invention uses a constraint unit to constrain half of the bag during the rotation and face-changing action of the rectangular device, so that the rectangular device can be more stable during the face-changing action.

[0018] 3. The present invention has a first slope installed. During the period when the rectangular device is displaced into the face-changing frame and fixed on the platform but has not been displaced into the displacement groove, the rectangular device can press the first slope to help the fixed platform to move into the displacement groove faster, allowing the rectangular device to move into the outer shell more smoothly. By installing a second slope, it is ensured that during the period when there is a deviation between the rectangular device and the area below the inner wall of the face-changing frame, the rectangular device can also be displaced into the inside of the face-changing frame, ensuring the operation of the face-changing action of the rectangular device.

[0032] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1-10An embodiment of the present invention provides an inspection platform for an AOI inspection machine, comprising a roller assembly line 12, a roller assembly line 2 13 installed on one side of the roller assembly line 12, and an assembly platform 14 fixedly connected between the roller assembly line 12 and the roller assembly line 2 13. An inspection unit is installed on both the roller assembly line 12 and the roller assembly line 2 13. The inspection unit comprises an assembly frame 111 installed on the sides of the roller assembly line 12 and the roller assembly line 2 13. The assembly frame 111 is fixedly connected to a motor 2 112. The output end of the motor 2 112 is connected to one end of a threaded rod 113 passing through the assembly frame 111. The other end of the threaded rod 113 is screwed to the assembly frame 111. The threaded rod 113 is threadedly connected to a displacement seat 114. A CCD camera 115 is installed on the lower side of the displacement seat 114. The upper wall of the displacement seat 114 fits with the assembly frame 111 to ensure smooth walking. The orientation of the CCD camera 115 can be changed to detect rectangular devices. It also includes a face-changing unit 15 installed on the top side of the assembly table 14, which is used to change the face of the rectangular device for detection. The face-changing unit 15 includes an assembly disc 152 fixedly connected to the top side of the assembly table 14. The central area of ​​the assembly disc 152 is screwed to a rotating rod 153. The end of the rotating rod 153 farther from the assembly disc 152 is connected to the power end of the motor 1. Face-changing frames 154 are installed at equal intervals on the assembly disc 152. Cooperation modules are installed inside the face-changing frames 154 to drive the displacement action of the rectangular device.

[0034] The constraint unit 16 is installed in the area closer to the cooperation module inside the face-changing frame 154, and is used to constrain and lock the rectangular device;

[0035] The cooperation module includes a hollow rubber air cushion 155 fixedly connected to the face-changing frame 154. A force-applying platform 1527 is installed on the wall of the hollow rubber air cushion 155 closer to the open area of ​​the face-changing frame 154. The force-applying platform 1527 is slidably connected to the face-changing frame 154. A hollow rubber air cushion 2 158 is installed on the wall of one side of the face-changing frame 154 closer to the hollow rubber air cushion 155. A connecting platform 156 is installed on the wall of the hollow rubber air cushion 158 farther from the open area of ​​the face-changing frame 154. The inner wall of the hollow rubber air cushion 155 closer to the connecting platform 156 and away from the opening of the face-changing frame 154 is reserved with connecting ports 157 that are penetrated and evenly spaced. The end of the connecting port 157 farther from the hollow rubber air cushion 155 passes through the connecting platform 156 and the hollow rubber air cushion 2 158 in sequence to the inside of the hollow rubber air cushion 2 158. The area inside the connecting platform 156 closer to the connecting port 157 is provided with a changing module for changing the opening condition of the connecting port 157.

[0036] During operation, the motor 1 pulls the assembly disc 152 to rotate until the lower wall of one of the face-changing frames 154 and the upper wall of the roller on the roller assembly line 12 are in a straight line. At this time, the motor 1 stops running. The selected motor 1 control must be accurate to ensure that the lowest point of the inner wall of one of the face-changing frames 154 and the upper wall of the roller in the roller assembly line 12 are in a straight line. At this time, the roller assembly line 12 pulls the rectangular device toward the direction closer to the inside of the face-changing frame 154. Due to the traction generated during the transportation of the roller assembly line 12 One end of the rectangular component on the roller assembly line 12 slowly contacts and presses against the force-applying platform 1527. The external force causes the force-applying platform 1527 to press against the hollow rubber air cushion 155. The pressure causes the air inside the hollow rubber air cushion 155 to flow into the hollow rubber air cushion 2 158 through the connection port 157. During this period, the rectangular component slowly moves into the face-changing frame 154. When the end of the rectangular component that is away from the face-changing frame 154 slowly escapes from the roller in the roller assembly line 12, the motor 1 is started, and the rotating rod 153 pulls the assembly disc 152 and the face-changing frame 154 to rotate in the forward direction.

[0037] The variable module further includes two connection cavities 1524 that are equally spaced and reserved in the assembly disc 152 and are closer to each connection cavity 1 1522. The connection cavities 1524 and 1522 are connected to each other. The wall of the connection cavity 1524 farther from the connection cavity 1522 is connected to the magnet 1 1525 via a spring. The areas on the upper walls of the roller assembly line 12 and the roller assembly line 2 13 that accommodate the magnet 1 1525 are connected to the magnet 2 1526. The adjacent sides of the magnet 1 1525 and the magnet 2 1526 repel each other.

[0038] The shift module includes an assembly cavity 159 reserved within the coupling platform 156 and located closer to the coupling port 157. The end of the coupling platform 156 farther from the face-changing frame 154 extends to the position of the assembly disc 152 and is connected to the assembly disc 152. The wall of the assembly cavity 159 closer to the hollow rubber air cushion 158 is connected to the first displacement platform 1510 via a spring. The wall of the first displacement platform 1510 is provided with a through hole 1521 at the position where the coupling port 157 is adapted. The inner area of ​​the assembly disc 152 closer to the coupling platform 156 is provided with a first coupling cavity 1522. The wall of the first coupling cavity 1522 farther from the coupling platform 156 is connected to the second displacement platform 1523 via a spring. The end of the first displacement platform 1510 farther from the hollow rubber air cushion 158 extends into the interior of the first coupling cavity 1522 and is fixedly connected to the second displacement platform 1523.

[0039] When the inner lower wall of one of the face-changing frames 154 and the upper wall of the roller in the roller assembly line 12 are in a straight line, the areas of magnet 2 1526 and magnet 1 1525 are adapted to each other. Because the sides of magnet 2 1526 and magnet 1 1525 that are close to each other repel each other, while the areas of magnet 2 1526 and magnet 1 1525 are adapted to each other, there is mutual repulsion between magnet 2 1526 and magnet 1 1525. The repulsion causes magnet 1 1525 to suppress the spring rebound between connecting chamber 2 1524 and move toward connecting chamber 1 1522 inside connecting chamber 2 1524, slowly compressing the air inside connecting chamber 2 1524, and compressing the air inside connecting chamber 2 1524 to move to The coupling chamber 1522 compresses the second displacement stage 1523, which compresses the second displacement stage 1523 and the spring rebound displacement stage 1510 between the coupling chamber 1522 and the spring rebound between the assembly chamber 159, pulling the first displacement stage 1510 toward a direction farther from the coupling chamber 1522, that is, pulling the through-port 1521 toward a direction closer to the coupling port 157. When the through-port 1521 and the force-applying platform 1527 are in a state of mutual connection, that is, the lower side of the inner wall of one of the face-changing frames 154 and the upper wall of the roller in the roller assembly line 12 are in a straight line, the coupling port 157 of the face-changing frame 154 that is adapted to each other is in an open stage, that is, it is convenient for the rectangular component to be displaced into the face-changing frame 154 for operation.

[0040] After the rectangular device is displaced into the face-changing frame 154, the rotating rod 153 pulls the assembly disc 152 to rotate, and the magnet 1 1525 rotates toward a direction farther from the magnet 2 1526. The area of ​​the magnet 1 1525 and the magnet 2 1526 gradually becomes farther away, and the repulsion between the magnet 2 1526 and the magnet 1 1525 gradually weakens. After the repulsion between the magnet 1 1525 and the magnet 2 1526 disappears, due to the spring rebound between the displacement stage 1 1510 and the assembly cavity 159 The first displacement stage 1510 is displaced in the assembly chamber 159 toward the first connection chamber 1522, and the through opening 1521 and the connection opening 157 gradually deviate from each other. In other words, the open area of ​​the connection opening 157 is blocked. In other words, during the rotation to change the face of the rectangular device, the opening of the connection opening 157 is completely blocked, preventing the air in the second hollow rubber air cushion 158 from circulating back and forcing the rectangular device to fall out of the face-changing frame 154, thereby hindering the face-changing operation of the rectangular device.

[0041] During the half-circle rotation of the face-changing frame 154, the lower inner wall of the face-changing frame 154 and the upper wall of the roller in the roller assembly line 2 13 are in a straight line. At this time, the motor 1 is not in operation, and the rectangular device achieves the purpose of half-circle rotation, that is, the purpose of face-changing. At this time, the areas of the magnet 1 1525 and the magnet 2 1526 in the roller assembly line 2 13 are adapted to each other, and repulsion occurs between the magnet 1 1525 and the magnet 2 1526. Therefore, the connection port 157 is in an open state. At this time, due to the spring rebound of the hollow rubber air cushion 2 158 and the hollow rubber air cushion 1 155, the air in the hollow rubber air cushion 2 158 flows back to the inside of the connection platform 156 through the connection port 157, allowing the hollow rubber air cushion 1 155 to slowly recover to its original shape. That is, the hollow rubber air cushion 155 slowly applies pressure on the force-applying platform 1527, and the connecting port 157 presses the rectangular device, and the pressure makes the rectangular device move toward a direction closer to the roller assembly line 2 13, and the rectangular device slowly moves to the roller assembly line 2 13. During the period when one end of the rectangular device moves to the roller assembly line 2 13, the roller assembly line 2 13 will also have a traction force, and the rectangular device moves toward a direction farther away from the face-changing frame 154, that is, it helps the rectangular device to escape from the face-changing frame 154 faster. During the period when the rectangular device moves to the roller assembly line 2 13, the roller assembly line 2 13 transports the rectangular device that has achieved face-changing to the position where the rectangular device is detected, that is, the face-changing and transporting action of the rectangular device is achieved; this is repeated to achieve the continuous face-changing action of the rectangular device.

[0042] The restraining unit 16 includes displacement channels 1610 reserved in the upper and lower walls of the face-changing frame 154 near the open area of ​​the face-changing frame 154. An outer shell 164 is mounted on both sides of the face-changing frame 154. The outer shell 164 and the displacement channels 1610 are arranged one-to-one. The inner side of the outer shell 164 is connected to a displacement rod 163 via a spring. The end of the displacement rod 163, which is farther from the outer shell 164, extends through the displacement channel 1610 into the face-changing frame 154 and is connected to the fixed platform 162.

[0043] The constraint unit 16 further includes connection channels 165 connected at equal intervals to the wall of the second connection chamber 1524 and closer to the area between the first magnet 1525 and the second magnet 1526. The connection channels 165 extend through the second connection chamber 1524 from one end farther from the second connection chamber 1524 to an area closer to the outer shell 164, and are connected to the outer shell 164. The connection channels 165 are located in an area farther from the side of the outer shell 164 than the face-changing frame 154. A temporary retention unit is installed in an area closer to the connection channels 165 on the inside of the assembly disc 152.

[0044] When the lower inner wall of one of the face-changing frames 154 and the upper wall of the roller on the roller assembly line 12 are in a straight line, that is, the magnet 1525 is displaced in the direction farther from the magnet 2 1526 in the connection chamber 2 1524. At this time, the air in the outer shell 164 is displaced into the connection chamber 2 1524 through the connection channel 165. At this time, due to the spring rebound between the displacement rod 163 and the outer shell 164, the displacement rod 163 pulls the fixed connection platform 162 to displace in the direction farther from the inside of the face-changing frame 154. When the assembly wafer 152 is displaced into the inside of the displacement platform 1510, As the rectangular device moves into the face-changing frame 154, the magnet 1 1525 rotates toward a direction farther from the magnet 2 1526, and the area of ​​the magnet 1 1525 and the magnet 2 1526 gradually becomes farther away. The repulsion between the magnet 2 1526 and the magnet 1 1525 gradually weakens. After the repulsion between the magnet 1 1525 and the magnet 2 1526 disappears, due to the spring rebound between the magnet 1 1525 and the connecting chamber 2 1524, the magnet 1 1525 moves toward a direction closer to the magnet 2 1526, compressing the air in the connecting chamber 2 1524, and the air is forced to pass through the connecting passage. The displacement rod 163 inside the outer shell 164 is pressed by the displacement rod 163, and the spring between the displacement rod 163 and the outer shell 164 rebounds and pulls the fixed connection platform 162 toward the direction closer to the rectangular device. When the fixed connection platform 162 and the rectangular device touch each other, the purpose of restraining half side is achieved, thereby preventing the rectangular device from escaping from the inside of the face changing frame 154 due to the rotation during the face changing action of the face changing frame 154 pulling the rectangular device to rotate and change the face, thereby making the rectangular device more stable during the rotation and face changing action. During the half-circle rotation of the face changing frame 154, the inner wall of the face changing frame 154 and the roller assembly line 11 are pressed against each other. 3. The upper wall of the roller is in a straight line, and the magnet 1525 is displaced in the direction farther from the magnet 2 1526 inside the connecting chamber 2 1524. At this time, the air inside the outer shell 164 is displaced to the inside of the connecting chamber 2 1524 through the connecting channel 165. At this time, due to the spring rebound between the displacement rod 163 and the outer shell 164, the displacement rod 163 pulls the fixed platform 162 to displace farther from the inside of the face-changing frame 154. When the assembly disc 152 is displaced to the inside of the displacement groove 1610, the constraint on the rectangular device is released, which facilitates the rectangular device to escape from the face-changing frame 154 and run.

[0045] The temporary retention unit includes a accommodating cavity 166 reserved inside the assembly disc 152 and closer to the connecting channel 165 area. The wall of the accommodating cavity 166 farther from the connecting channel 165 is connected to the force-applying plate 167 via a spring sliding. After the fixing platform 162 and the rectangular device touch each other, the magnet 1 1525 presses the excess air toward the magnet 2 1526 during the displacement to the inside of the accommodating cavity 166 to press the force-applying plate 167, so that the force-applying plate 167 is displaced toward a direction farther from the connecting channel 165, thereby achieving the goal of temporarily retaining the air and ensuring that the compressed air can be temporarily retained during the change in the distance between the upper and lower sides of the rectangular device, thereby ensuring the operation of the various upper and lower side distance constraint actions of the rectangular device.

[0046] Several rollers are arranged at equal intervals inside roller assembly line 12 and roller assembly line 2 13. The upper wall of the roller and the lower inner wall of the face changing frame 154 are in a straight line to ensure the operation of the rectangular component when it is moved into the face changing frame 154.

[0047] The wall surface of the assembly disc 152 that is farther away from the face-changing frame 154 is reserved with a slope 168, and the area below the inner wall of the face-changing frame 154 that is farther away from the face-changing frame 154 is reserved with a slope 168. By installing the slope 168, when the rectangular device moves into the face-changing frame 154 but the fixed connection platform 162 has not moved into the displacement groove 1610, the rectangular device can press the slope 168 to help the fixed connection platform 162 move into the displacement groove 1610 faster, ensuring that the rectangular device moves into the outer shell 164 normally. By installing the slope 2 169, when the rectangular device moves to an area closer to the slope 2 169, it can move into the outer shell 164 through the slope 2 169, ensuring that when there is a deviation between the area of ​​the rectangular device and the area below the inner wall of the face-changing frame 154, the rectangular device can also move into the inside of the face-changing frame 154, ensuring the operation of the face-changing action of the rectangular device.

[0048] The specific implementation method is as follows: during operation, the rectangular device is placed on the roller assembly line 12. After being placed on the roller assembly line 12, the roller assembly line 12 is operated to slowly move the rectangular device to a position closer to the face-changing frame 154. The rectangular device slowly moves to the inside of the face-changing frame 154. During this period, the rectangular device is detected by the detection part installed on the roller assembly line 12.
