The first material transfer device is disposed on one side of the loading and unloading platform along the first horizontal direction, and the material pusher is disposed on one side of the first material transfer device along the second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction; The first material transfer device is used to move the material box on the upper platform to the material box docking position, and the material pusher is used to push the material strip in the material box located at the material box docking position out of the material box along the first horizontal direction. The first material transfer device is also used to move the material box on the middle platform to the material box docking position, and to move the material box located at the material box docking position to the middle platform or the lower platform. The vision inspection system includes a second material transfer device and a vision inspection device; the second material transfer device is used to transfer the strip to be pushed out of the material box to the vision inspection device, and to transfer the inspected strip into the material box located at the docking position.

[0006] As an improvement to the above technical solution, the first material transfer device includes a first driving member, a first support, a second driving member, a third driving member, a first clamping mechanism, and a second clamping mechanism. The second driving member, the third driving member, the first clamping mechanism, and the second clamping mechanism are all disposed on the first bracket. The first driving member is used to drive the first bracket to move closer to and away from the loading and unloading platform along the second horizontal direction. The first clamping mechanism and the second clamping mechanism are spaced apart along the vertical direction. The first driving member is used to drive the first clamping mechanism to move up and down along the vertical direction, and the second driving member is used to drive the second clamping mechanism to move up and down along the vertical direction. The material box docking positions are all spaced apart from the loading and unloading platform along the second horizontal direction.

[0008] As an improvement to the above technical solution, a feeding mechanism is provided on the upper platform, the middle platform and the lower platform. The feeding mechanism is used to drive the material box placed on the feeding mechanism to move along the second horizontal direction.

[0009] As an improvement to the above technical solution, the feeding mechanism has a first conveyor belt and a sixth driving member, the sixth driving member being able to drive the first conveyor belt to move the material box located on the first conveyor belt along a second horizontal direction.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention relates to a visual inspection machine for strips of material with RGV loading and unloading. The RGV automatic loading and unloading device places a box containing strips to be inspected on an upper platform and an empty box on a middle platform. A first driving member drives a first support to move in a second horizontal direction, a second driving member drives a first clamping mechanism to move in a vertical direction, and a third driving member drives a second clamping mechanism to move in a vertical direction. This allows the first clamping mechanism to grip the box containing the strips to be inspected on the upper platform and move it to the box docking position. A pushing device pushes one strip from the box at the docking position for subsequent visual inspection. The first clamping mechanism then moves the gripped box from the docking position... After the first clamping mechanism moves the empty material box located on the middle platform, it is moved to the material box docking position. The inspected material strip is placed back into the empty material box located at the material box docking position by the vision inspection device. The second clamping mechanism moves the clamped material box away from the material box docking position, and the first clamping mechanism moves the clamped material box back to the material box docking position. The above process is repeated until all the material strips in the material box containing the material strips to be inspected have been inspected. The first clamping mechanism places the material box containing all the material strips that have been pushed out onto the middle platform, and the second clamping mechanism places the material box full of inspected material strips onto the lower platform. The RGV automatic loading and unloading equipment continuously places the material box containing the material strips to be inspected onto the upper platform and removes the material box from the lower platform.

[0014] The present invention relates to a visual inspection machine for RGV loading and unloading, which enables loading and unloading (material boxes) of the material into and out of the visual inspection system from the same side of the RGV automatic loading and unloading equipment, and loading and unloading (material strips) of the visual inspection system through the loading and unloading system. This improves the space utilization efficiency of the work area and facilitates centralized loading and unloading operations. Furthermore, the supply of material strips to the visual inspection device and the recycling of material strips after inspection are both automated, which further improves the efficiency of material strip inspection.

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] like Figures 1-6As shown, this embodiment provides a visual inspection machine for RGV (Remote Generation Vehicle) strip loading and unloading, including a loading and unloading system and a visual inspection system. The loading and unloading system includes a loading and unloading platform 1, a first transfer device 2, and a pusher device 3. The loading and unloading platform 1 includes an upper platform 11, a middle platform 12, and a lower platform 13 arranged sequentially from top to bottom along the vertical direction Z. The first transfer device 2 is disposed on one side of the loading and unloading platform 1 along the first horizontal direction X, and the pusher device 3 is disposed on one side of the first transfer device 2 along the second horizontal direction Y, which is perpendicular to the first horizontal direction X. The first transfer device 2 is used to move the cassette on the upper platform 11 to the cassette docking position, and the pusher device 3 is used to push the strip (semiconductor product) in the cassette located at the cassette docking position out of the cassette along the first horizontal direction X. The first transfer device 2 is also used to move the cassette on the middle platform 12 to the cassette docking position, and to move the cassette located at the cassette docking position onto the middle platform 12 or the lower platform 13. The vision inspection system includes a second material transfer device 4 and a vision inspection device 5. The second material transfer device 4 is used to transfer the strip to be ejected from the material box to the vision inspection device 5, and to transfer the inspected strip into the material box located at the docking position.

[0022] The strip visual inspection machine for RGV loading and unloading provided in this embodiment places a box containing strips to be inspected on the upper platform 11 using an RGV automatic loading and unloading device, and places an empty box on the middle platform 12. A first driving member 21 drives a first support 22 to move along the second horizontal direction Y, a second driving member 23 drives a first clamping mechanism 25 to move along the vertical direction Z, and a third driving member 24 drives a second clamping mechanism 26 to move along the vertical direction Z. This allows the first clamping mechanism 25 to clamp the box containing the strips to be inspected on the upper platform 11 and move it to the box docking position. A pushing device 3 pushes out one of the strips from the box at the docking position for subsequent inspection by the strip visual inspection equipment. The first clamping mechanism 25 then... The box is displaced from the docking position of the material box. The second clamping mechanism 26 can clamp the empty material box located on the middle platform 12 and move it to the docking position of the material box. The detected material strip is put back into the empty material box located at the docking position by the vision inspection device. The second clamping mechanism 26 displaces the clamped material box from the docking position of the material box. The first clamping mechanism 25 moves the clamped material box back to the docking position of the material box. The above process is repeated until all the material strips in the material box containing the material strips to be tested have been tested. The first clamping mechanism 25 places the material box on the middle platform 12 after all the material strips have been pushed out. The second clamping mechanism 26 places the material box full of the tested material strips on the lower platform 13. The RGV automatic loading and unloading equipment continuously places the material box containing the material strips to be tested on the upper platform 11 and removes the material box on the lower platform 13.

[0023] The present invention provides a visual inspection machine for RGV loading and unloading of material strips. This machine enables loading and unloading (material boxes) of the material strips onto and off the visual inspection system from the same side of the RGV automatic loading and unloading device, and loads and unloads (material strips) the visual inspection system via the loading and unloading system. This improves the space utilization efficiency of the work area and facilitates centralized loading and unloading operations. Furthermore, the supply of material strips to the visual inspection device 5 and the recycling of material strips after inspection are both automated, further improving inspection efficiency. In this embodiment, both the second material transfer device 4 and the visual inspection device 5 utilize existing equipment in the art.

[0024] Optionally, such as Figures 1-4 As shown, the first material transfer device 2 includes a first driving member 21, a first support 22, a second driving member 23, a third driving member 24, a first clamping mechanism 25, and a second clamping mechanism 26. The second driving member 23, the third driving member 24, the first clamping mechanism 25, and the second clamping mechanism 26 are all mounted on the first support 22. The first driving member 21 drives the first support 22 to move the second driving member 23, the third driving member 24, the first clamping mechanism 25, and the second clamping mechanism 26 closer to and further away from the loading / unloading platform 1 along the second horizontal direction Y. The first clamping mechanism 25 and the second clamping mechanism 26 are spaced apart along the vertical direction Z. The first driving member 21 drives the first clamping mechanism 25 to move up and down along the vertical direction Z, and the second driving member 23 drives the second clamping mechanism 26 to move up and down along the vertical direction Z. The material box docking position is spaced apart from the loading / unloading platform 1 along the second horizontal direction Y. The first drive member 21 drives the first bracket 22 to move along the second horizontal direction Y, the second drive member 23 drives the first clamping mechanism 25 to move along the vertical direction Z, and the third drive member 24 drives the second clamping mechanism 26 to move along the vertical direction Z. This allows the first clamping mechanism 25 and the second clamping mechanism 26 to approach the loading / unloading platform 1 to clamp the material box on it, move the material box to the loading position and the material box docking position, and return the material box to the loading / unloading platform 1 after loading and unloading are completed. In this embodiment, the first drive member 21 is a lead screw stepper motor.

[0025] Furthermore, such as Figures 1-4As shown, the first material transfer device 2 also includes a first transmission mechanism 201, a first slide 202, a second transmission mechanism 203, and a second slide 204. The first slide 202 and the second slide 204 are both slidably connected to the first bracket 22. The second driving member 23 is connected to the first slide 202 via the first transmission mechanism 201. The first clamping mechanism 25 is disposed on the first slide 202. The second driving member 23 can drive the first slide 202 to move the first clamping mechanism 25 in the vertical direction Z via the first transmission mechanism 201. The third driving member 24 is connected to the second slide 204 via the second transmission mechanism 203. The second clamping mechanism 26 is disposed on the second slide 204. The third driving member 24 can drive the second slide 204 to move in the vertical direction via the second transmission mechanism 203.

[0026] Furthermore, such as Figures 1-4 As shown, the first transmission mechanism 201 includes a first synchronous belt transmission assembly 2011 and a first ball screw 2012. Those skilled in the art will understand that the synchronous belt transmission assembly includes a driving pulley, a driven pulley, and a synchronous belt. Both the driving pulley and the driven pulley of the first synchronous belt transmission assembly 2011 are rotatably mounted on the first bracket 22. The output end of the second driving member 23 is connected to the driving pulley of the first synchronous belt transmission assembly 2011, and the driven pulley of the first synchronous belt transmission assembly 2011 is fixedly connected to the lead screw of the first ball screw 2012. The output end of the first ball screw 2012 is fixedly connected to the first slide block 202. In this embodiment, the second driving member 23 is a motor. The second driving member 23 drives the lead screw of the first ball screw 2012 to rotate through the first synchronous belt transmission assembly 2011, thereby driving the first slide block 202 to move in the vertical direction Z. The second transmission mechanism 203 includes a second synchronous belt transmission assembly 2031 and a second ball screw 2032. The driving and driven pulleys of the second synchronous belt transmission assembly 2031 are rotatably mounted on the first bracket 22. The output end of the third driving member 24 is connected to the driving pulley of the second synchronous belt transmission assembly 2031, and the driven pulley of the second synchronous belt transmission assembly 2031 is fixedly connected to the lead screw of the second ball screw 2032. The output end of the second ball screw 2032 is fixedly connected to the second slide 204. In this embodiment, the third driving member 24 is a motor. The third driving member 24 drives the lead screw of the second ball screw 2032 to rotate via the second synchronous belt transmission assembly 2031, thereby driving the second slide 204 to move in the vertical direction Z.

[0027] Furthermore, such as Figures 1-4As shown, the first clamping mechanism 25 includes a first gripper assembly 251 and a fourth driving member 252. The fourth driving member 252 is used to drive the first gripper assembly 251 to open and close in the vertical direction Z. The second clamping mechanism 26 includes a second gripper assembly 261 and a fifth driving member 262. The fifth driving member 262 is used to drive the second gripper assembly 261 to open and close in the vertical direction Z. The upper platform 11, middle platform 12, and lower platform 13 are all provided with clearance notches 101 at their ends near the first material transfer device 2. The clearance notches 101 are used to avoid the first gripper assembly 251 and / or the second gripper assembly 261. The clearance notches 101 enable the first gripper assembly 251 and the second gripper assembly 261, which open and close in the vertical direction Z, to grip the material box on the loading / unloading platform 1 and to place the material box back onto the loading / unloading platform 1. Those skilled in the art will understand that when the first gripper group 251 and the second gripper group 261 grip the material box located on the loading and unloading platform 1, the first gripper group 251 and the second gripper group 261 grip the part of the bottom surface of the material box located at the avoidance notch 101 and the top surface.

[0028] Furthermore, such as Figures 1-4 As shown, the first gripper group 251 includes a first gripper 2511 and a second gripper 2512 disposed opposite to each other. The first clamping mechanism 25 also includes a first mounting plate 253 fixedly connected to the first slide block 202. The first gripper 2511 and the fourth driving member 252 are both fixedly connected to the first mounting plate 253. The second gripper 2512 is slidably connected to the first mounting plate 253. The output end of the fourth driving member 252 is connected to the second gripper 2512 in a transmission connection. The fourth driving member 252 can drive the second gripper 2512 to move closer to and away from the first gripper 2511. The second gripper assembly 261 includes a third gripper 2611 and a fourth gripper 2612 disposed opposite to each other. The second clamping mechanism 26 also includes a second mounting plate 263 fixedly connected to the second slide block 204. The third gripper 2611 and the fifth drive member 262 are both fixedly connected to the second mounting plate 263. The fourth gripper 2612 is slidably connected to the second mounting plate 263. The output end of the fifth drive member 262 is driveably connected to the fourth gripper 2612. The fifth drive member 262 can drive the fourth gripper 2612 to move closer to and away from the third gripper 2611. In this embodiment, the first clamping mechanism 25 also includes a third ball screw. The fourth drive member 252 is driveably connected to the second gripper 2512 through the third ball screw. The second clamping mechanism 26 also includes a fourth ball screw. The second clamping mechanism 26 is driveably connected to the fourth gripper 2612 through the fourth ball screw. Both the fourth drive member 252 and the fifth drive member 262 are lead screw stepper motors.

[0029] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, feeding mechanisms 102 are provided on the upper platform 11, middle platform 12, and lower platform 13. The feeding mechanisms 102 drive the material boxes placed on them to move along the second horizontal direction Y. By providing feeding mechanisms 102 on the upper platform 11 and middle platform 12, when placing material boxes on the upper platform 11 and middle platform 12, the material boxes can be placed at the end of the platforms and middle platform 12 away from the first material transfer device 2, and then the feeding mechanisms 102 move the material boxes to the end of the upper platform 11 and middle platform 12 closer to the first material transfer device 2. Similarly, by providing a feeding mechanism 102 on the lower platform 13, after the first material transfer device 2 has collected the material boxes at the docking position and placed them on the lower platform 13, the feeding mechanisms 102 on the lower platform 13 transport the material boxes to the end of the lower platform 13 away from the first material transfer device 2. In summary, by setting up feeding mechanisms 102 on the upper platform 11, the middle platform 12, and the lower platform 13, the loading (placing material boxes on the upper and lower platforms 1) and unloading (collecting material boxes from the upper and lower platforms 1) of the loading and unloading platform 1 can be carried out at the end of the loading and unloading platform 1 away from the first material transfer device 2 and the pushing device 3, thereby avoiding mutual interference between the loading and unloading of the loading and unloading platform 1 and the operation of the first material transfer device 2 and the pushing device 3, thus facilitating the loading and unloading of the loading and unloading platform 1.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the feeding mechanism 102 has a first conveyor belt and a sixth driving member 1021. The sixth driving member 1021 can drive the first conveyor belt to move the material box located on the first conveyor belt along the second horizontal direction Y. Specifically, in this embodiment, the feeding mechanism 102 includes a sixth driving member 1021, a third synchronous belt drive assembly 1022, and a fourth synchronous belt drive assembly 1023. The sixth driving member 1021 is connected to the driving wheel of the third synchronous belt drive assembly 1022, and the sixth driving member 1021 can drive the driving wheel of the third synchronous belt drive assembly 1022 to rotate. The driven wheel of the third synchronous belt drive assembly 1022 is connected to the driving wheel of the fourth synchronous belt drive assembly 1023, so that the driven wheel of the third synchronous belt drive assembly 1022 can drive the driving wheel of the fourth synchronous belt drive assembly 1023 to rotate. The first conveyor belt is the synchronous belt of the fourth synchronous belt drive assembly 1023. In this embodiment, the sixth driving member 1021 is a motor.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, multiple first conveyor belts of the same feeding mechanism 102 are spaced apart along a first horizontal direction X. That is, in this embodiment, the feeding mechanism 102 has multiple fourth synchronous belt drive assemblies 1023. The feeding mechanism 102 also includes a transmission rod 1024, through which the driven wheel of the third synchronous belt drive assembly 1022 is connected to the driving wheel of each fourth synchronous belt drive assembly 1023, so that the driven wheel of the third synchronous belt drive assembly 1022 can drive multiple fourth synchronous belt drive assemblies 1023.

[0032] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, both the upper platform 11 and the middle platform 12 are equipped with fixed baffles 103. The upper platform 11 is also equipped with a first movable baffle 104, and the middle platform 12 is equipped with a second movable baffle 105. The fixed baffles 103 and the first movable baffles 104 on the upper platform 11 are spaced apart along the first horizontal direction X, and the fixed baffles 103 and the second movable baffles 105 on the middle platform 12 are spaced apart along the first horizontal direction. The fixed baffles 103, the first movable baffles 104, and the second movable baffles 105 are all provided with guide slopes at the ends near the first material transfer device 2. The guide slope of the first movable baffle 104 and the guide slope of the fixed baffle 103 on the upper platform 11 form a flared opening, which facilitates the accurate placement of the material box onto the upper platform 11 and the middle platform 12.

[0033] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the feeding device 3 includes a second bracket 31, a seventh driving member 32, and a feeding plate 33. Both the seventh driving member 32 and the feeding plate 33 are mounted on the second bracket 31, and the seventh driving member 32 is connected to the second bracket 31. The seventh driving member 32 drives the feeding plate 33 to extend and retract along a first horizontal direction X. The extension of the feeding plate 33 pushes the material strip in the material box located at the material box docking position out of the material box. Specifically, in this embodiment, the feeding device 3 also includes a fifth synchronous belt drive assembly 35. The seventh driving member 32 drives the drive wheel of the fifth synchronous belt drive assembly 35, and the feeding plate 33 is connected to the synchronous belt of the fifth synchronous belt drive assembly 35, causing the feeding plate 33 to reciprocate. In this embodiment, the seventh driving member 32 is a motor.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the pushing device 3 also includes an eighth driving member 34, which is connected to the pushing device 3 and is used to drive the pushing device 3 to move closer to and further away from the first material transfer device 2 along the first horizontal direction X. By changing the relative position of the pushing device 3 and the first material transfer device 2 along the first direction X, the pushing device 3 in this embodiment can adapt to material strips of different lengths, that is, it can push material strips of different lengths out of the material box. Specifically, in this embodiment, the pushing device 3 also includes a sixth synchronous belt drive assembly 36. The second bracket 31 is connected to the synchronous belt of the sixth synchronous belt drive assembly 36. The eighth driving member 34 drives the drive wheel of the sixth synchronous belt drive assembly 36, and the synchronous belt of the sixth synchronous belt drive assembly 36 drives the second bracket 31 to move along the first direction X. In this embodiment, the eighth driving member 34 is a motor.

[0035] Optionally, such as Figure 1 As shown, the visual inspection machine for RGV loading and unloading also includes a frame 6, a loading and unloading platform 1, a first material transfer device 2 and a pushing device 3 are all mounted on the frame 6, wherein the second bracket 31 of the pushing device 3 is slidably connected to the frame 6.

[0036] The working principle of the visual inspection machine for RGV loading and unloading provided in this embodiment is as follows: An empty material box is placed on the middle platform 12 of the loading and unloading platform 1 for turnover and the QR code of the material box is read manually; The RGV (Rail Guided Vehicle) automatic loading and unloading equipment places the box containing the strip to be tested on the upper platform 11 at the end away from the first support 22. The feeding mechanism 102 on the upper platform 11 moves the box containing the strip to be tested to the end of the upper platform 11 closer to the first support 22. The barcode reader set above the loading and unloading platform 1 reads the QR code of the box containing the strip to be tested. The first clamping mechanism 25 picks up the box containing the strip to be tested on the upper platform 11, and the second clamping mechanism 26 picks up the empty box on the middle platform 12. The RGV automatic loading and unloading equipment places a new box containing the strip to be tested on the upper platform 11.

[0037] The first clamping mechanism 25 and the second clamping mechanism 26 operate independently. The first clamping mechanism 25 moves the cassette containing the strip to be tested to the cassette docking position, and the pushing device 3 pushes one of the strips to be tested out of the cassette. The second transfer device 4 clamps the strip to be tested that has been pushed out of the cassette, pulls the strip to be tested completely out of the cassette, and conveys it to the vision inspection device 5 for inspection. Before inspection, the strip's QR code is read. The first clamping mechanism 25 moves the cassette containing the strip to be tested away from the cassette docking position, and the second clamping mechanism 26 moves the turnover cassette to the cassette docking position. After the strip to be tested is inspected on the strip vision inspection device, the second transfer device 4 pushes the inspected strip into the cassette on the second clamping mechanism 26; the second clamping mechanism 26 moves the cassette away from the cassette docking position, and the first clamping mechanism 25 moves the cassette to be tested back to the cassette docking position. The pushing device 3 then pushes the cassette to be tested back into the cassette. One of the strips to be tested is ejected from the box, and the above process is repeated until all the strips to be tested in the box held by the first clamping mechanism 25 are ejected for testing. The first clamping mechanism 25 places the empty box on the middle platform 12 for turnover, and grabs a new box containing strips to be tested from the upper platform 11. After the box held by the second clamping mechanism 26 is filled with the tested strips, it is placed on the lower platform 13, and an empty box is grabbed from the middle platform 12.

[0038] The RGV automatic loading and unloading equipment removes the material box filled with the tested material strips from the lower platform 13.

[0039] The system runs in a loop, binding the detection information of the completed material strips with the material strip's QR code information, and binding the material strip's QR code information with the QR code information of the material box into which it was placed after detection, so as to facilitate subsequent traceability.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
