DETAILED DESCRIPTION

[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 in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. 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 1-10The embodiment of the present invention provides an inspection platform of 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. The roller assembly line 12 and the roller assembly line 2 13 are both installed with an inspection unit. 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 with 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 position 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 assembly disc 152 is screwed to a rotating rod 153 in the central area. 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 evenly spaced 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 restraint unit 16 installed in the area closer to the cooperation module in the face-changing frame 154 is used to restrain 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 application 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 application platform 1527 and the face changing frame 154 are slidably connected, 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 1 155, and a connecting platform 156 is installed on the wall of the hollow rubber air cushion 2 158 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 arranged at equal intervals. The end of the connecting port 157 farther from the hollow rubber air cushion 155 extends to the inside of the hollow rubber air cushion 2 158 through the connecting platform 156 and the hollow rubber air cushion 2 158 in sequence. 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 assembled disc 152 to rotate until the lower wall of the face-changing frame 154 in the plurality of layers 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, and the motor 1 is controlled accurately to ensure that the lowest point of the inner wall of the face-changing frame 154 in the plurality of layers and the upper wall of the roller in the roller assembly line 12 are in a straight line accurately. At this time, the roller assembly line 12 pulls the rectangular device to move closer to the inside of the face-changing frame 154. Under the traction force generated during the transportation of the roller assembly line 12 One end of the rectangular device on the roller assembly line 12 slowly contacts and presses the force application platform 1527. The external force causes the force application platform 1527 to press the hollow rubber air cushion 155. The pressure causes the air in 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 device slowly moves to the inside of the face-changing frame 154. When the end of the rectangular device that is away from the face-changing frame 154 slowly escapes from the roller in the roller assembly line 12, the motor 1 is operated to pull the assembly disc 152 and the face-changing frame 154 to rotate in the positive direction through the rotating rod 153.

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

[0038] The change module includes an assembly cavity 159 reserved inside the connection platform 156 and closer to the connection port 157. The end of the connection 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 displacement platform 1 1510 via a spring. The wall of the displacement platform 1 1510 is adapted to the position of the connection port 157 and a through hole 1521 is reserved. The area inside the assembly disc 152 closer to the connection platform 156 is reserved with the connection cavity 1522. The wall of the connection cavity 1522 farther from the connection platform 156 is connected to the displacement platform 2 1523 via a spring. The end of the displacement platform 1 1510 farther from the hollow rubber air cushion 158 extends to the inside of the connection cavity 1522 and is fixedly connected to the displacement platform 2 1523.

[0039] When the lower wall inside one of the face-changing frames 154 and the upper wall surface 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, and the repulsion causes magnet 1 1525 to suppress and cause the spring rebound between connecting chamber 2 1524 to move in the direction of connecting chamber 1 1522 near connecting chamber 1524, and slowly compress the air inside connecting chamber 2 1524, causing the air inside connecting chamber 2 1524 to move to The coupling chamber 1522 compresses the displacement stage 2 1523, and the displacement stage 2 1523 compresses and the spring rebound displacement stage 1510 between the coupling chamber 1522 and the spring rebound between the assembly chamber 159 to pull the displacement stage 1510 to move in a direction farther from the coupling chamber 1522, that is, to pull the through port 1521 to move in a direction closer to the coupling port 157, until the through port 1521 and the force application stage 1527 are in a state of mutual connection, that is, the lower inner wall of one of the face-changing frames 154 in the plurality of layers and the upper wall of the roller in the roller assembly line 12 are in a straight line, and the coupling ports 157 of the face-changing frames 154 that are adapted to each other are in an open stage, that is, it is convenient for the rectangular device to move 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 moves farther away, and the repulsion between the magnet 2 1526 and the magnet 1 1525 gradually decays. 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 displacement stage 1510 is displaced in the assembly cavity 159 toward the direction closer to the connection cavity 1522, and the through port 1521 and the connection port 157 are gradually deviated, that is, the open area of ​​the connection port 157 is blocked, that is, during the rotation to change the face of the rectangular device, the opening of the connection port 157 is blocked, preventing the air in the hollow rubber air cushion 2 158 from circulating back and causing the rectangular device to be forced to escape from the face-changing frame 154, resulting in obstacles to the face-changing action 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 running, 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 initial shape. That is, the hollow rubber air cushion 155 slowly applies pressure on the force application platform 1527, and the connection port 157 compresses the rectangular device, which 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 traction, and the rectangular device moves toward a direction farther 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 constraint unit 16 includes a displacement platform 1510 reserved on the upper wall and the lower wall of the face-changing frame 154 near the open area of ​​the face-changing frame 154. The outer shell 164 is installed on both sides of the face-changing frame 154. The outer shell 164 and the displacement channel 1610 are installed one-to-one with each other. The inner side of the outer shell 164 is connected to the displacement rod 163 through a spring sliding. The end of the displacement rod 163 farther from the outer shell 164 extends to the inner side of the face-changing frame 154 through the displacement channel 1610 and is connected to the fixed connection platform 162.

[0043] The constraint unit 16 further includes a connection channel 165 which is connected to the wall of the connection chamber 1524 at equal intervals and is closer to the area between the magnet 1525 and the magnet 1526, and extends through the connection chamber 1524, and the end of the connection channel 165 which is farther from the connection chamber 1524 extends to the area closer to the outer shell 164, and is connected to the outer shell 164 through the connection channel 165. The connection channel 165 is located in the area farther from the side of the outer shell 164 from the face-changing frame 154, and a temporary retention unit is installed in the area closer to the connection channel 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, and 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, and when the assembly wafer 152 is displaced to 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 moves farther away, and the repulsion between the magnet 2 1526 and the magnet 1 1525 gradually decays. 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 connection chamber 2 1524, the magnet 1 1525 moves toward a direction closer to the magnet 2 1526, compressing the air in the connection chamber 2 1524, and the air is forced to pass through the connection passage The displacement rod 163 inside the outer shell 164 is pressed by the displacement rod 163, and the spring rebound between the displacement rod 163 and the outer shell 164 pulls the fixed connection platform 162 to move closer to the rectangular device, until the fixed connection platform 162 and the rectangular device touch each other, thereby achieving the purpose of restraining half side, 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 1 The upper wall of the roller 3 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 connection platform 162 to displace toward a direction farther from the inside of the face changing frame 154, and waits until the assembly disc 152 is displaced to the inside of the displacement groove 1610, the constraint on the rectangular device is released, so that the rectangular device can escape from the face changing frame 154 for operation.

[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 to the inside of the accommodating cavity 166 during the displacement toward the magnet 2 1526 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 upper and lower side distance of the rectangular device, thereby ensuring the operation of the various upper and lower side distance constraint actions of the rectangular device.

[0046] A number of rollers are evenly spaced inside roller assembly line 12 and roller assembly line 2 13, and the upper wall of the roller and the lower inner wall of the face changing frame 154 are in a straight line, ensuring the operation of the rectangular component displacement 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 is displaced into the face changing frame 154 but the fixed connection platform 162 has not been displaced into the displacement groove 1610, the rectangular device can press the slope 168 to help the fixed connection platform 162 to move faster into the displacement groove 1610, thereby ensuring that the rectangular device moves into the outer shell 164 normally. By installing the slope 2 169, when the rectangular device is displaced to an area closer to the slope 2 169, it can be displaced into the outer shell 164 through the slope 2 169, thereby 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 be displaced into the face changing frame 154, thereby 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 is slowly moved 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.
