Description

Technical Field

[0001] This invention relates to the field of machine vision inspection technology, and more particularly to an inspection device. Background Technology

[0002] With the continuous development of technology, smart devices have become an indispensable tool in people's lives. While pursuing performance, people are also constantly increasing their requirements for the appearance of smart devices. The phone cover is a key component of smart devices, directly affecting their performance and appearance. Therefore, the appearance inspection of phone cover is a crucial part of the smart device manufacturing process. Before being put into use, the phone cover needs to undergo a coating treatment to ensure that it achieves corresponding scratch resistance, drop resistance, and fingerprint resistance. Therefore, pre-coating inspection can greatly improve the pass rate after coating.

[0003] In the inspection of pre-coated cover plates, existing technologies mainly fall into two categories: manual inspection and machine vision inspection. Manual inspection involves using measuring instruments (such as 2D image measuring instruments, magnifying glasses, and film rulers) to directly read instrument readings or visually inspect the cover plate surface under auxiliary lighting to assess and measure appearance defects. However, manual inspection is susceptible to subjective factors, resulting in high error rates, unstable inspection quality, and low efficiency, making it difficult to guarantee consistent product quality. More importantly, it poses a health risk of vision impairment for inspection workers. Furthermore, manual inspection is labor-intensive and costly in mass production. Machine vision inspection uses robotic arms to pick up and move phone cover plates during transport. Since the pre-coated cover plates do not yet possess the scratch resistance, impact resistance, and high hardness required for coating, they are easily scratched and deformed, leading to a high scrap rate. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a testing device, mainly used to solve the problems of existing mobile phone cover plate testing being labor-intensive or easily scratched and deformed.

[0005] To achieve the above objectives, the present invention mainly provides the following technical solutions:

[0006] This invention provides a detection device, which includes:

[0007] At least one tabletop assembly, the tabletop assembly including at least a transfer power assembly and a conveyor belt, the conveyor belt being connected to the transfer power assembly, the conveyor belt being used to support the object to be inspected, and the transfer power assembly being used to drive the conveyor belt to move and transport the object to be inspected;

[0008] At least one image acquisition component, which is opposite to the table component, is used to acquire an image of the object to be inspected on the conveyor belt.

[0009] This invention proposes a detection device that primarily uses a conveyor belt to support the object to be detected. A transfer power component drives the conveyor belt to move, thereby transporting the object. During transport, image acquisition and other detection processes are performed on the object, enabling automatic detection and avoiding damage caused by clamping and movement. In existing technologies, manual detection methods suffer from drawbacks such as high misjudgment rates, unstable detection quality, and low detection efficiency due to the influence of human subjectivity. Machine vision detection, which uses robotic arms to pick up and move phone covers, is prone to scratches and deformation. Compared to existing technologies, in this application, the object to be detected is placed above the conveyor belt, supported by the conveyor belt below. The transfer power component drives the conveyor belt to transport the object, allowing it to sequentially pass through image acquisition components or other auxiliary detection devices along the transport path. This achieves automatic detection without human intervention, resulting in high accuracy and avoiding damage to the object caused by robotic arm clamping and movement. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the specific implementation, structure, features and effects of the detection device proposed according to the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0029] like Figure 1 As shown, this embodiment of the invention provides a detection device for fixing a mobile phone frame 10. The detection device includes:

[0030] At least one tabletop assembly 01, the tabletop assembly 01 includes at least a transfer power assembly and a conveyor belt, the conveyor belt is connected to the transfer power assembly, the conveyor belt is used to support the object to be tested 03, and the transfer power assembly is used to drive the conveyor belt to move and transfer the object to be tested 03.

[0031] At least one image acquisition component 02, which is opposite to the table component 01, is used to acquire an image of the object to be inspected 03 on the conveyor belt.

[0032] The object to be tested 03 can be of various types, such as the mobile phone cover mentioned above, or other parts of the mobile phone, such as the mid-frame, or it can be a part that is not on the mobile phone, such as a computer casing or any other part that needs to be surface tested.

[0033] The tabletop assembly 01 can be a single unit or multiple units. Different tabletop assemblies 01 can have different structures to perform different detection functions. Alternatively, the tabletop assemblies 01 can have the same structure, enabling simultaneous detection of multiple objects 03 to be detected. For example, at least one tabletop assembly 01 may include at least one of a first tabletop assembly 1 and a second tabletop assembly 6. It may also include only... Figure 2 The multiple first tabletop components 1 shown may also include only those such as Figure 14 The multiple second platform components 6 are shown. Alternatively, in one embodiment, at least one platform component 01 includes both a first platform component 1 and a second platform component 6. The second platform component 6 is located behind the first platform component 1 in the direction of conveying the object to be detected 03. There are multiple image acquisition components 02, and each of the first platform component 1 and the second platform component 6 is associated with an image acquisition component 02, so that different detections can be performed respectively, such as detections under different directions and different lighting conditions.

[0034] In the following embodiments of this application, the following is used as... Figure 1 Taking the detection device shown as an example, in the embodiments below of this application, the direction is defined as: the first direction is as follows Figure 1 The Z direction is the direction in which the conveyor belt supports the object to be tested 03, which is vertical in actual use; the second direction is the X direction, which is perpendicular to the conveying direction of the object to be tested 03 and also perpendicular to the Z direction in which the conveyor belt supports the object to be tested 03; the third direction is the Y direction, which is the conveying direction of the object to be tested 03.

[0035] like Figure 1 As shown, the testing equipment includes two first tabletop components 1 and two second tabletop components 6. The two first tabletop components 1 are arranged side by side in the X direction, and the second tabletop components 6 correspond one-to-one with the first tabletop components 1 and are located behind the first tabletop components 1 in the Y direction. This arrangement allows for the simultaneous transfer and testing of two objects 03. Through the structural design of the first tabletop components 1 and the second tabletop components 6, a single combination of a first tabletop component 1 and a single second tabletop component 6 can simultaneously transfer and test two objects 03. Therefore, the entire equipment can simultaneously transfer and test four objects 03, thereby increasing testing efficiency.

[0036] The first table assembly 1 and the second table assembly 6 each include their own transfer power assembly and conveyor belt. The conveyor belt moves in a rolling manner under the action of the transfer power assembly. The object to be tested 03 is placed on the conveyor belt. The movement of the object to be tested 03 is achieved by the rolling of the conveyor belt and the friction between the conveyor belt and the object to be tested 03. It is worth noting that both the first table assembly 1 and the second table assembly 6 include multiple conveyor belts, and there are gaps between adjacent conveyor belts, which can be used to provide light. The following will describe this in detail with reference to specific embodiments.

[0037] The image acquisition component 02 can be a combination of multiple cameras. The image acquisition component 02 can further include an upper image acquisition component and a lower image acquisition component, which are respectively set above and below the conveyor belt. This enables the acquisition of images of the object to be detected 03 on the conveyor belt from a top-to-bottom perspective from the top, and the acquisition of images of the object to be detected 03 on the conveyor belt from a bottom-to-top perspective from the bottom.

[0038] In one embodiment, the detection device further includes a rack assembly 9, to which the table assembly 01 and the image acquisition assembly 02 are connected. The rack assembly 9 may be a frame structure, serving to support and accommodate the structures on the table assembly 01.

[0039] This invention discloses a detection device that primarily uses a conveyor belt to support the object to be detected. A transfer power component drives the conveyor belt to move, thereby transporting the object. During transport, image acquisition and other detection processes are performed on the object, enabling automatic detection and avoiding damage caused by clamping or movement. In existing technologies, manual detection methods suffer from drawbacks such as high misjudgment rates, unstable detection quality, and low efficiency due to the influence of human subjectivity. Machine vision detection, which uses robotic arms to pick up and move phone covers, is prone to scratches and deformation. Compared to existing technologies, in this application, the object to be detected is placed above the conveyor belt, supported by the conveyor belt below. The transfer power component drives the conveyor belt to transport the object, allowing it to sequentially pass through image acquisition components or other auxiliary detection devices along the transport path. This achieves automatic detection without human intervention, resulting in high accuracy and avoiding damage to the object caused by robotic arm clamping or movement.

[0040] In the following embodiments, the implementation methods of the first countertop assembly 1 and the second countertop assembly 6 will be described in detail by way of example.

[0041] At least one tabletop assembly 01 includes at least one first tabletop assembly 1, and at least one image acquisition assembly 02 includes at least one first image acquisition element 3. The first tabletop assembly 1 is at least correspondingly provided with at least one first image acquisition element 3. The detection device includes multiple drive shaft assemblies, multiple conveyor assemblies, and multiple conveyor belts. The first tabletop assembly 1 includes a first drive shaft assembly from the multiple drive shaft assemblies, at least one of the multiple conveyor assemblies, and at least one of the multiple conveyor belts. The first drive shaft assembly is connected to the conveyor assembly, and the conveyor belt is connected to the conveyor assembly. The first drive shaft assembly is used to provide power to the conveyor assembly, and the conveyor assembly is used to drive the conveyor belt to move.

[0042] The first tabletop assembly 1 also includes a first mounting base plate 29, which is connected to the frame assembly 9. The first mounting base plate 29 is used to support and fix the various components included in the first tabletop assembly 1. The first image acquisition element 3 may include two upper image acquisition elements and two lower image acquisition elements, the functions of which are as described above and will not be repeated here.

[0043] like Figure 2 As shown, the first platform assembly 1 includes multiple conveying components and multiple conveyor belts. The multiple conveying components include a first single-axis assembly 13, a three-axis assembly 14, a second single-axis assembly 15, a third single-axis assembly 16, a first double-axis assembly 17, a second double-axis assembly 18, and an extension coupling assembly 19, which are arranged sequentially in the conveying direction of the object to be inspected 03 and are drivenly connected to the first drive shaft assembly. The multiple conveyor belts include a first conveyor belt 20, a second conveyor belt 21, a third conveyor belt 22, a fourth conveyor belt 23, and a fifth conveyor belt 24. The first conveyor belt 20 is wound around the first single-axis assembly 13 and the three-axis assembly 14; the second conveyor belt 21 is wound around the three-axis assembly 14 and the second single-axis assembly 15; the third conveyor belt 22 is wound around the third single-axis assembly 16 and the first double-axis assembly 17; the fourth conveyor belt 23 is wound around the first double-axis assembly 17 and the second single-axis assembly 15; and the fifth conveyor belt 24 is wound around the second single-axis assembly 15 and the extension coupling assembly 19.

[0044] The first conveyor belt 20, the second conveyor belt 21, the third conveyor belt 22, the fourth conveyor belt 23, and the fifth conveyor belt 24 can each be in pairs, arranged side-by-side with intervals in the second direction. This provides more stable support for the object to be tested 03 in the second direction, and the position detection and rotation of the object to be tested 03 can be performed between the two parallel conveyor belts. The first single-axis assembly 13, the three-axis assembly 14, the second single-axis assembly 15, the third single-axis assembly 16, the first double-axis assembly 17, the second double-axis assembly 18, and the extension coupling assembly 19 are all arranged at intervals. The conveyor belts are connected by wrapping around the conveying assembly, and the movement of the conveyor belts is driven by the rotation of a portion of the conveying assembly.

[0045] The following is a detailed description of the conveyor assembly structure, using a specific example of a drive shaft assembly:

[0046] In one embodiment, the first drive shaft assembly includes a first drive shaft assembly 25 and a first driven shaft assembly 26, which extend in the conveying direction of the object to be tested 03. The first drive shaft assembly 25 and the first driven shaft assembly 26 are respectively disposed on both sides of the conveyor belt in a second direction, perpendicular to the conveying direction of the object to be tested 03 and perpendicular to the direction in which the conveyor belt supports the object to be tested 03. Among the plurality of conveying assemblies, some conveying assemblies are connected to the first drive shaft assembly 25, and other conveying assemblies are connected to the first driven shaft assembly 26. The first drive shaft assembly 25 is used to directly or indirectly connect to the drive force assembly 5. The drive shaft assembly also includes a synchronization assembly 27, to which both the first drive shaft assembly 25 and the first driven shaft assembly 26 are connected, so that the first driven shaft assembly 26 rotates synchronously with respect to the first drive shaft assembly 25.

[0047] Setting up a first drive shaft assembly 25 and a first driven shaft assembly 26 allows multiple conveying components to be arranged in different directions, reducing space occupation. The first drive shaft assembly 25 can be integrated or separate in three directions. More specifically, the first drive shaft assembly 25 further includes a first sub-drive shaft assembly and a second sub-drive shaft assembly, such as... Figure 3 The diagram illustrates one implementation of the first sub-drive shaft assembly. The first sub-drive shaft assembly includes a first sub-drive shaft 251, two first mounted bearings 252, a first magnetic coupling 253, and two first bearing retaining rings 254. The two first mounted bearings 252 are spaced apart in a third direction and connected to a first mounting base plate 29. The first sub-drive shaft 251 passes through the two first mounted bearings 252. The first magnetic coupling 253 is located at the tail end of the first sub-drive shaft 251 in the direction of conveying the object to be tested 03. The first bearing retaining rings 254 are fitted onto the first sub-drive shaft 251 and are used to limit the position of the first mounted bearings 252. Figure 4As shown, the second sub-drive shaft assembly includes a second sub-drive shaft 255, two second mounted bearings 256, two second magnetic couplings 257, and two second bearing retaining rings 258. The two second mounted bearings 256 are spaced apart in a third direction and connected to the first mounting base plate 29. The second sub-drive shaft 255 passes through the two second mounted bearings 256. The second magnetic couplings 257 are located at the beginning and end of the second sub-drive shaft 255 in the direction of conveying the object to be tested 03. The second bearing retaining rings 258 are sleeved on the second sub-drive shaft 255 and are used to limit the position of the second mounted bearings 256. The second magnetic coupling 257 at the beginning of the second sub-drive shaft 255 in the direction of conveying the object to be tested 03 is used to connect with the first magnetic coupling 253 at the end of the first sub-drive shaft 251 in the direction of conveying the object to be tested 03. This enables mating and conveying. The main drive assembly 5 can be directly connected to the first sub-drive shaft assembly and the second sub-drive shaft assembly, or it can be set in the second platform assembly 6, which will be described in detail below with reference to the second platform assembly 6.

[0048] The first driven shaft assembly 26 further includes a first sub-driven shaft assembly and a second sub-driven shaft assembly, such as Figure 5 The diagram illustrates one implementation of the first driven shaft assembly. The first driven shaft assembly includes a first driven shaft 261, two third bearings 262, a third magnetic coupling 263, and two third bearing retaining rings 264. The two third bearings 262 are spaced apart in a third direction and connected to a first mounting base plate 29. The third driven shaft 261 passes through the two third bearings 262. The third magnetic coupling 263 is located at the beginning of the third driven shaft 261 in the direction of conveying the object 03 to be tested. The third bearing retaining rings 264 are fitted onto the third driven shaft 261 and are used to limit the position of the third bearings 262. Figure 6 As shown, the second driven shaft assembly includes a second driven shaft 265, a fourth bearing 266, and a fourth magnetic coupling 267. The fourth bearing 266 is connected to an additional mounting plate 291 mounted on the first mounting base plate 29. The second driven shaft 265 passes through the fourth bearing 266. The fourth magnetic coupling 267 is located at the end of the second driven shaft 265 in the direction of conveying the object to be tested 03, and is connected to a third magnetic coupling 263.

[0049] The first drive shaft assembly 25 and the first driven shaft assembly 26 rotate synchronously through the transmission of the synchronization assembly 27. The synchronization assembly 27 can be implemented in the following ways:

[0050] like Figure 10As shown, the synchronization assembly 27 includes a timing belt 271, a tensioning wheel shaft 272, a tensioning wheel 273, a tensioning wheel bracket 274, and two timing pulleys 275. The two timing pulleys 275 are respectively connected to the first drive shaft assembly 25 and the first driven shaft assembly 26. The timing belt 271 is wound around the two timing pulleys 275. The tensioning wheel shaft 272 is connected to the tensioning wheel bracket 274. The tensioning wheel 273 is rotatably connected to the tensioning wheel shaft 272 and rolls against the timing belt 271 to adjust the tension of the timing belt 271.

[0051] Two synchronous pulleys 275 can be connected to the first sub-drive shaft 251 and the first sub-driven shaft 261 respectively, driving the first drive shaft assembly 25 and the first driven shaft assembly 26 to rotate synchronously via the synchronous pulleys 275 and the synchronous belt 271. The number of tension wheel shafts 272, tension wheels 273, and tension wheel brackets 274 can all be two. The two tension wheel brackets 274 are spaced apart in the second direction and connected to the first mounting base plate 29. The two tension wheels 273 are respectively mounted on the two tension wheel brackets 274 via the tension wheel shafts 272, thereby achieving spaced compression of the synchronous belt 271 in the second direction, allowing for a wide range of adjustment of the tension of the synchronous belt 271.

[0052] In one embodiment, the synchronization component 27 further includes at least one tensioning pulley adjustment mechanism 276. The tensioning pulley shaft 272 is connected to the tensioning pulley bracket 274 via the tensioning pulley adjustment mechanism 276. The tensioning pulley adjustment mechanism 276 is used to adjust the position of the tensioning pulley shaft 272 in the direction in which the conveyor belt supports the object to be tested 03. This allows for adjustment of the tension of the synchronous belt 271. Specifically, the tensioning pulley adjustment mechanism 276 may include an adjusting block and an adjusting bolt. The adjusting block is connected to the tensioning pulley shaft 272, and a slot extending in a first direction is provided on the adjusting block. The adjusting bolt fixes the adjusting block to the tensioning pulley bracket 274 through the slot. By adjusting the position of the adjusting bolt in the slot, the height of the adjusting block can be changed, thereby changing the height of the tensioning pulley 273, i.e., changing the degree of compression of the synchronous belt 271 by the tensioning pulley 273, and thus changing the tension of the synchronous belt 271.

[0053] In some embodiments, the synchronization component 27 may also include a belt guard 276, which covers the timing belt 271 between the two tensioning wheel shafts 272 and is connected to the first mounting base plate 29, serving to include the timing belt 271.

[0054] The aforementioned first single-axis assembly 13 is driven and connected to the second sub-driven shaft assembly; the triple-axis assembly 14 is driven and connected to the first sub-drive shaft assembly; the second single-axis assembly 15 is driven and connected to the first sub-driven shaft assembly; the third single-axis assembly 16 is driven and connected to the first sub-drive shaft assembly; and the first double-axis assembly 17, the second double-axis assembly 18, and the extension coupling assembly 19 are all driven and connected to the second sub-drive shaft assembly. The aforementioned first drive shaft assembly 25 and first driven shaft assembly 26 are separately configured to avoid the inconvenience of long shaft installation and to make equipment maintenance and disassembly more convenient.

[0055] The driving connection between the conveying assembly and the first drive shaft assembly 25 and the first driven shaft assembly 26 can be various, such as gear meshing drive or magnetic drive. In one embodiment, the first sub-drive shaft 251, the second sub-drive shaft 255, the first sub-driven shaft 261, and the second sub-driven shaft 265 are each equipped with a second transmission member 258 corresponding to each conveying assembly. The second transmission member 258 can drive the conveying assembly through magnetism. Using magnetic drive offers high accuracy, low wear, and high transmission efficiency. The following detailed description, in conjunction with the specific structure of the conveying assembly, provides further details:

[0056] Each conveying assembly includes a bearing housing 131 and at least one shaft assembly 132. The bearing housing 131 is connected to the first mounting base plate 29, the shaft assembly 132 is connected to the bearing housing 131, and the shaft assembly 132 is drive-connected to the first drive shaft assembly.

[0057] The first single-axis assembly 13, the second single-axis assembly 15, and the third single-axis assembly 16 each include only a single axis assembly 132, while the triple-axis assembly 14 includes two axis assemblies 132 and an auxiliary axis located between the two axis assemblies 132. The auxiliary axis may have the same structure as the axis assembly 132 or a different structure. The auxiliary axis is used to cooperate with the positioning assembly 10 (described later) to position the object to be tested 03. The first double-axis assembly 17 and the second double-axis assembly 18 each include two axis assemblies 132. The extension coupling assembly 19 may include only a single axis assembly 132 if the second platform assembly 6 is not provided, or it may include two axis assemblies 132 if the second platform assembly 6 is provided. The axis assembly 132 located on the rear side of the transmission direction of the object to be tested 03 is used to connect with the second platform assembly 6.

[0058] In the following embodiments, the structure is further described using the first single-axis assembly 13 as an example:

[0059] like Figure 6-8As shown, the shaft assembly 132 includes an end cap 1321, a spacer 1322, a conveyor shaft 1323, a round nut 1324, a bearing 1325, and a first transmission member 1326. The spacer 1322 is rotatably connected to the end cap 1321. The conveyor shaft 1323 is connected to the end cap 1321 and the spacer 1322. The round nut 1324 is disposed on the conveyor shaft 1323 and located on one side of the spacer 1322. The bearing 1325 is sleeved on the conveyor shaft 1323 and located on the other side of the spacer 1322. The round nut 1324 is used to fix the inner ring of the bearing 1325. The end cap 1321 is connected to the bearing seat 131 and cooperates with the bearing seat 131 to fix the outer ring of the bearing 1325. The first transmission member 1326 is disposed on the conveyor shaft 1323 and is located at the end of the spacer 1322 opposite to the round nut 1324. Among them, the first transmission component 1326 is the driven magnetic wheel, and the second transmission component 258 is the driving magnetic wheel.

[0060] During driving, the first active shaft assembly 25 and the first driven shaft assembly 26 rotate synchronously through the synchronization assembly 27. The active magnetic wheel magnetically drives the driven magnetic wheel, causing all shaft assemblies 132 to rotate synchronously. Then, through friction with the conveyor belt, the conveyor belt is driven to roll, thereby conveying the object to be tested 03.

[0061] In one implementation, such as Figure 9 As shown, encoder couplings 1510 are respectively provided on the second single-axis assembly 15 and the second double-axis assembly 18. An encoder 1520 is connected to the encoder coupling 1510, which can detect the actual rotation of the conveyor shaft 1323 of the second single-axis assembly 15 and the conveyor shaft 1323 of the second double-axis assembly 18. In case of abnormal rotation, such as step loss, the machine can be stopped and adjusted in real time.

[0062] In one embodiment, the detection device further includes a plurality of positioning components 10. The first image acquisition component 3 is positioned at a first shooting position corresponding to the first table component 1 in the support direction of the object to be detected 03. The positioning component 10 is disposed in front of the first shooting position in the conveying direction of the object to be detected 03. The positioning component 10 is used to move the object to be detected 03 to a preset direction.

[0063] Before the object to be tested 03 enters the first table assembly 1 and before the first image acquisition unit 3 captures an image of the object to be tested 03, the position of the object to be tested 03 is adjusted so that the object to be tested 03 is aligned. Specifically, the positioning assembly 10 is located below the three-axis assembly 14, and the first image acquisition unit 3 is located between the second single-axis assembly 15 and the third single-axis assembly 16.

[0064] In one implementation, such as Figure 11As shown, the positioning assembly 10 includes a positioning mechanism base plate 101, a positioning drive, a transmission assembly, a first positioning part, and a second positioning part. Both the positioning drive and the transmission assembly are connected to the positioning mechanism base plate 101. The positioning mechanism base plate 101 includes a linear guide 10101 extending in a second direction. The first and second positioning parts are slidably connected to the linear guide 10101 and to the transmission assembly. The first and second positioning parts are arranged on both sides of the object to be tested 03 in the second direction. The positioning drive is used to drive the first and second positioning parts closer together via the transmission assembly to adjust the position of the object to be tested 03; alternatively, the positioning drive is used to drive the first and second positioning parts further apart via the transmission assembly to release the object to be tested 03.

[0065] The positioning mechanism base plate 101 is fixed to the first mounting base plate 29. The linear guide 10101 may further include a guide rail fixed to the positioning mechanism base plate 101 and extending in a second direction, and a slider slidably connected to the guide rail. Linear guides 10101 may be respectively provided on both sides of the positioning mechanism base plate 101 in a third direction, with the first positioning part and the second positioning part connected to the slider. A transmission assembly is used to drive the first positioning part and the second positioning part to move closer to each other, thereby clamping the object to be tested 03 from both sides to adjust the position of the object to be tested 03.

[0066] The transmission assembly is designed to drive the first positioning part and the second positioning part to move in the same or opposite directions. It includes a first synchronous pulley 102, a second synchronous pulley 103, and a synchronous belt 104. The first synchronous pulley 102 is connected to the output end of the positioning drive member, and the second synchronous pulley 103 is spaced apart from the positioning drive member in a second direction. The synchronous belt 104 is wound around the first synchronous pulley 102 and the positioning drive member, and the first and second positioning parts are respectively connected to the synchronous belt 104 located on different sides of the first synchronous pulley 102.

[0067] like Figure 11 As shown in the figure, the first positioning part is located on the front area of ​​the timing belt 104, and the second positioning part is located on the rear area of ​​the timing belt 104. When the timing belt 104 rolls, the front and rear areas of the timing belt 104 will move in opposite directions, thereby driving the first and second positioning parts to move in opposite directions.

[0068] There are various ways to fix the first and second positioning parts to the synchronous belt 104. For example, the first and second positioning parts may have the same structure. The first positioning part includes a guide rail pad 105, a positioning plate 106, a synchronous belt pressure plate 109, and a synchronous belt pressure plate 1010. The guide rail pad 105 is slidably connected to the linear guide 10101, such as to the slider. The positioning plate 106 is connected to the guide rail pad 105. The synchronous belt pressure plate 1010 is connected to the positioning plate 106. The synchronous belt pressure plate 109 is connected to the synchronous belt pressure plate 1010. The synchronous belt pressure plate 109 and the synchronous belt pressure plate 1010 clamp the synchronous belt 104 between their opposite sides. The positioning assembly 10 also includes a guide plate mounting plate 107 and a guide plate 108. The guide plates 108 on the first and second positioning parts are respectively provided with guide plate mounting plates 107. The two guide plates 108 are respectively connected to the two guide plate mounting plates 107. The guide plates 108 are used to contact the object to be tested 03.

[0069] The guide plate 108 is a plate-like structure extending in a vertical plane formed by a first direction and a third direction, thereby enabling it to contact the side wall of the object to be tested 03 and adjust the position of the object to be tested 03. In one embodiment, the guide plate 108 is provided with a clearance notch, and the guide plate 108 is used to nest the outer side of a portion of the conveying component through the guide notch, such as nesting it outside the aforementioned auxiliary shaft, to make way for the auxiliary shaft.

[0070] In one embodiment, the positioning assembly 10 further includes a positioning sensor 1011 and a sensing plate 1012. The sensing plate 1012 is fixed on the first positioning part and / or the second positioning part, and the positioning sensor 1011 is fixed on the base plate 101 of the positioning mechanism. The sensing plate 1012 is used to follow the movement of the first positioning part and / or the second positioning part. When the positioning sensor 1011 is triggered, the first positioning part and the second positioning part adjust the object to be detected 03 into position.

[0071] The positioning sensor 1011 can be a photoelectric switch, and the sensing plate 1012 can be a blocking plate. When the position of the object to be detected 03 needs to be adjusted, the first positioning part and the second positioning part are driven to move relative to each other until the sensing plate 1012 enters the light range of the positioning sensor 1011, blocking the light and triggering the positioning sensor 1011 to send a positioning signal. At this time, the guide plates 108 of the first and second positioning parts are pressed and corrected by the sides of the object to be detected 03. Then, the first positioning part and the second positioning part can be driven to move away from each other and move away from the object to be detected 03.

[0072] In one implementation, such as Figure 12 As shown, the first platform assembly 1 also includes a first light assembly 11, which is located at the same position as the first image acquisition unit 3 in the direction of conveying the object to be tested 03. The light from the first light assembly 11 is used to project onto the object to be tested 03 between the conveying components.

[0073] The first optical component 11 and the first image acquisition unit 3 are both located between the second single-axis component 15 and the third single-axis component 16. By setting the first optical component 11 to correspond with the first image acquisition unit 3, when the first image acquisition unit 3 acquires an image, supplementary lighting is provided by the first optical component 11, which can realize the acquisition of defects under illumination conditions. Through other optical devices in the following embodiments, it is possible to acquire images of the object to be inspected 03 under different illumination conditions.

[0074] The first optical component 11 includes two first light source modules, which are arranged opposite each other on both sides of the object to be detected 03 in a second direction. This achieves symmetrical light supply to the object to be detected 03.

[0075] The first light source module includes at least two first light sources, and different first light sources are used to project different light onto the object to be detected 03, which can increase the diversity of illumination.

[0076] The specific form of the first light source can be set as needed. For example, at least two first light sources can be used, including a first strip light source 111 and an arc light source 112. On the first side of the object to be tested 03 in the second direction, the first strip light source 111 is located behind the arc light source 112 in the conveying direction of the object to be tested 03. On the second side of the object to be tested 03 in the second direction, the first strip light source 111 is located in front of the arc light source 112 in the conveying direction of the object to be tested 03. The first strip light source 111 is used to project a first strip light onto the object to be tested 03, and the arc light source 112 is used to project an arc light onto the object to be tested 03.

[0077] In one embodiment, the first light component 11 further includes a first support frame assembly, to which the first light source is connected. The first support frame assembly is used to adjust the position of the first light source in at least three mutually perpendicular directions.

[0078] like Figure 12As shown, two first strip light sources 111 and two arc light sources 112 are each provided with a first support frame assembly. The first support frame assembly includes a first light source connector 113, a first adapter 114, a second adapter 115, and a third adapter 116. The first light source connector 113 is connected to the first light source, and the first light source connector 113 is connected to the first adapter 114. The first adapter 114 can be adjusted in position in the first direction. For example, the first adapter 114 may have a strip-shaped hole extending vertically. A bolt passes through the strip-shaped hole to fix the first light source connector 113. The height of the first light source connector 113 can be adjusted by adjusting the position of the bolt in the strip-shaped hole, thereby achieving position adjustment in the first direction. The first adapter 114 is connected to the second adapter 115, and the second adapter 115 is connected to the third adapter 116. The second adapter 115 can also be adjusted in position in the second direction. For example, the second adapter 115 may have a strip-shaped hole extending in the second direction. The specific adjustment method is similar to that described above and will not be repeated here. The third adapter 116 is fixed to the first mounting base plate 29, or to the bearing seat 131 of the conveying assembly, as required for fixing. The third adapter 116 is used to adjust the position in the third direction, such as by providing a slot extending in the third direction on the third adapter 116.

[0079] In one implementation, such as Figure 13 As shown, the first platform assembly 1 further includes a second light assembly 12, and at least one image acquisition assembly 02 includes a second image acquisition element 4. The second light assembly 12 and the second image acquisition element 4 are located at the same position in the corresponding conveying direction of the object to be detected 03. The light from the second light assembly 12 is used to project onto the object to be detected 03. The second light assembly 12 and the first light assembly 11 are arranged at intervals in the conveying direction of the object to be detected 03, and the second light assembly 12 is used to provide light different from that of the first light assembly 11.

[0080] The second optical component 12 and the first optical component 11 provide different light sources to the object to be detected 03, thereby enabling the second image acquisition unit 4 and the first image acquisition unit 3 to acquire images of the object to be detected 03 under different lighting conditions. The second optical component 12 can correspond to the two axis components 132 of the second dual-axis assembly 18. The second image acquisition unit 4 can include two upper image acquisition units and two lower image acquisition units, and its function is the same as that in the aforementioned embodiment, which will not be repeated here.

[0081] The second light component 12 includes two second light sources, which are arranged opposite each other on both sides of the object to be detected 03 in a second direction, so as to provide a symmetrical lighting environment for the object to be detected 03 in the second direction.

[0082] In one embodiment, the second light source includes a second strip light source 121, which is used to project a second strip light onto the object to be detected 03.

[0083] The second light component 12 also includes a universal support frame assembly, to which the second strip light source 121 is connected. The universal support frame assembly is used to adjust the position of the second strip light source 121 in at least three mutually perpendicular directions.

[0084] like Figure 13 As shown, the universal support frame assembly includes a second light source connector 122, a fifth adapter 124, and a sixth adapter 125. The second light source connector 122 is connected to the second strip light source 121. The second light source connector 122 is connected to the fifth adapter 124 and its position is adjustable in the first direction. The fifth adapter 124 is connected to the sixth adapter 125 and its position is adjustable in the third direction. The sixth adapter 125 is fixed to the first mounting base plate 29 and is used for adjusting its position in the second direction. The position adjustment in the first, second, and third directions is described above using the method of engaging the strip holes and adjusting bolts, and will not be detailed here.

[0085] In one embodiment, the first tabletop assembly 1 further includes at least one first detection element 28, which is disposed between multiple conveying assemblies and is used to detect the position of the object to be detected 03.

[0086] The first detection element 28 can be of various types, such as an infrared sensor. The position of the object to be detected 03 can be determined through the first detection element 28, thereby determining whether to activate the second image acquisition element 4 and the first image acquisition element 3 for imaging, and whether to activate the positioning component 10 for positioning. For example, multiple first detection elements 28 can be respectively positioned between the first single-axis component 13 and the triple-axis component 14 to provide a reference signal for the activation of the positioning component 10; positioned between the triple-axis component 14 and the second single-axis component 15 to provide a reference signal for the activation of the first image acquisition element 3 and the first optical component 11; and positioned in front of the second dual-axis component 18 to provide a reference signal for the activation of the second image acquisition element 4 and the second optical component 12.

[0087] In one embodiment, at least one platform assembly 01 includes at least one second platform assembly 6, and at least one image acquisition assembly 02 includes a third image acquisition element 7, with the second platform assembly 6 corresponding to the third image acquisition element 7. The detection device includes multiple drive shaft assemblies, multiple conveyor assemblies, and multiple conveyor belts. The second platform assembly 6 includes a second drive shaft assembly from the multiple drive shaft assemblies, at least one of the multiple conveyor assemblies, and at least one of the multiple conveyor belts. The second drive shaft assembly is connected to the conveyor assembly, and the conveyor belt is connected to the conveyor assembly. The second drive shaft assembly provides power to the conveyor assembly, and the conveyor assembly drives the conveyor belt to move.

[0088] The following embodiments describe various embodiments of the second tabletop assembly 6, wherein some embodiments include components that are the same as those of the first tabletop assembly 1 and have the same names. However, it is understood that this refers to the detection device including multiple of the components, the first tabletop assembly 1 including a portion of the multiple components, and the second tabletop assembly 6 including another portion of the multiple components.

[0089] The second tabletop assembly 6 also includes a second mounting base plate 75, which is connected to the frame assembly 9. The second mounting base plate 75 is used to support and fix the various components included in the second tabletop assembly 6. The third image acquisition unit 7 may include two upper image acquisition units and two lower image acquisition units, the functions of which are as described above and will not be repeated here.

[0090] like Figure 2 As shown, the second platform assembly 6 includes multiple conveying components and multiple conveyor belts. The multiple conveying components include a fourth single-axis assembly 63, a fifth single-axis assembly 64, a third double-axis assembly 65, a sixth single-axis assembly 66, and a seventh single-axis assembly 67, which are arranged sequentially in the conveying direction of the object to be inspected 03 and are driven and connected to the second drive shaft assembly. The second conveyor belts include a sixth conveyor belt 68, a seventh conveyor belt 69, and a ninth conveyor belt 70. The sixth conveyor belt 68 is wound around the fourth single-axis assembly 63 and the aforementioned extension coupling assembly 19. The seventh conveyor belt 69 is wound around the fifth single-axis assembly 64 and the third double-axis assembly 65. The ninth conveyor belt 70 is wound around the sixth single-axis assembly 66 and the seventh single-axis assembly 67.

[0091] The sixth conveyor belt 68, the seventh conveyor belt 69, and the ninth conveyor belt 70 can each be in pairs, arranged side-by-side with intervals in the second direction. This provides more stable support for the object to be tested 03 in the second direction, and the position detection and rotation of the object to be tested 03 can be performed between the two parallel conveyor belts. The fourth single-axis assembly 63, the fifth single-axis assembly 64, the third double-axis assembly 65, the sixth single-axis assembly 66, and the seventh single-axis assembly 67 are all arranged at intervals. The conveyor belts are connected by wrapping around the conveying assembly, and the movement of the conveyor belts is driven by the rotation of a portion of the conveying assembly's structure.

[0092] In one embodiment, the second drive shaft assembly includes a second drive shaft assembly 73 and a second driven shaft assembly 74. The second drive shaft assembly 73 and the second driven shaft assembly 74 extend in the conveying direction of the object to be tested 03. The second drive shaft assembly 73 and the second driven shaft assembly 74 are respectively disposed on both sides of the second conveyor belt in a second direction perpendicular to the conveying direction of the object to be tested 03 and perpendicular to the direction in which the conveyor belt supports the object to be tested 03. Among the plurality of second conveying assemblies, some are connected to the second drive shaft assembly 73, and others are connected to the second driven shaft assembly 74. The second drive shaft assembly 73 is used to directly or indirectly connect to the drive force assembly 5. The second drive shaft assembly also includes a synchronization assembly 27. Both the second drive shaft assembly 73 and the second driven shaft assembly 74 are connected to the synchronization assembly 27 so that the second driven shaft assembly 74 rotates synchronously with the second drive shaft assembly 73.

[0093] The device includes two synchronization components 27, one belonging to the first drive shaft assembly and the other to the second drive shaft assembly. The second drive shaft assembly 73 and the second driven shaft assembly 74 allow multiple conveying components to be arranged in different directions, reducing space requirements.

[0094] The second drive shaft assembly 73 includes a drive shaft, two fifth bearing housings, a single fifth magnetic coupling, and two fourth bearing retaining rings. The two fifth bearing housings are spaced apart in a third-direction upward direction and connected to the second mounting base plate 75. The drive shaft passes through the two fifth bearing housings, and the fifth magnetic coupling is located at the beginning of the drive shaft in the direction of conveying the object to be tested 03. The fourth bearing retaining rings are fitted on the drive shaft and are used to limit the position of the fifth bearing housings. The second driven shaft assembly 74 includes a third sub-driven shaft assembly and a fourth sub-driven shaft assembly. The third sub-driven shaft assembly includes a third sub-driven shaft, two sixth bearing housings, a sixth magnetic coupling, and two fifth bearing retaining rings. The two sixth bearing housings are spaced apart in a third-direction upward direction and connected to the second mounting base plate 75. The third sub-driven shaft passes through the two sixth bearing housings, and the sixth magnetic coupling is located at the end of the driven shaft in the direction of conveying the object to be tested 03. The fifth bearing retaining rings are fitted on the third sub-driven shaft and are used to limit the position of the sixth bearing housings. The fourth driven shaft assembly includes a fourth driven shaft, a seventh mounted bearing, and a seventh magnetic coupling. The seventh mounted bearing is connected to an additional mounting plate provided on the second mounting base plate 75. The fourth driven shaft passes through the seventh mounted bearing, and the seventh magnetic coupling is located at the first end of the fourth driven shaft in the direction of conveying the object to be tested. The seventh magnetic coupling is connected to the sixth magnetic coupling.

[0095] There are two synchronization components 27. The first drive shaft assembly 25 and the first driven shaft assembly 26 rotate synchronously through the transmission of one of the two synchronization components 27. The second drive shaft assembly 73 and the second driven shaft assembly 74 rotate synchronously through the transmission of the other of the two synchronization components 27. The structure of the synchronization component 27 of the second drive shaft assembly is the same as described above, and will not be repeated here. The difference is that the tension wheel bracket 274 of the synchronization component 27 of the second drive shaft assembly is connected to the second mounting base plate 75.

[0096] The aforementioned fourth single-axis assembly 63 is driven to the second drive axis assembly 73, the fifth single-axis assembly 64 is driven to the third sub-driven axis assembly, the third double-axis assembly 65 is driven to the third sub-driven axis assembly, the sixth single-axis assembly 66 is driven to the second drive axis assembly 73, and the seventh single-axis assembly 67 is driven to the fourth sub-driven axis assembly.

[0097] The driving connection between the conveying assembly and the second drive shaft assembly 73 and the second driven shaft assembly 74 can be varied, such as gear meshing drive or magnetic drive. In one embodiment, the second drive shaft assembly, the third sub-driven shaft, and the fourth sub-driven shaft are each equipped with a second transmission member 258 corresponding to a specific conveying assembly. The second transmission member 258 can drive the conveying assembly via magnetism. Using magnetic drive offers high accuracy, low wear, and high transmission efficiency.

[0098] The specific structures of the fourth single-axis assembly 63, the fifth single-axis assembly 64, the sixth single-axis assembly 66, and the seventh single-axis assembly 67 are similar to those of the first single-axis assembly 13, and the specific structure of the third double-axis assembly 65 is similar to that of the first double-axis assembly 17, which will not be described again here. The difference is that the bearing housing 131 of the fourth single-axis assembly 63, the fifth single-axis assembly 64, the sixth single-axis assembly 66, the seventh single-axis assembly 67, and the third double-axis assembly 65 is connected to the second mounting base plate 75.

[0099] In one embodiment, an encoder coupling 1510 is provided on the fourth single-axis assembly 63, and an encoder 1520 is connected to the encoder coupling 1510. This enables the detection of the actual rotation of the conveyor shaft 1323 of the fourth single-axis assembly 63, and allows for real-time adjustments such as stopping the machine in case of abnormal rotation, such as step loss.

[0100] During operation, the second active shaft assembly 73 and the second driven shaft assembly 74 rotate synchronously through the synchronization assembly 27. The active magnetic wheel magnetically drives the driven magnetic wheel, causing all shaft assemblies 132 to rotate synchronously. Then, through friction with the conveyor belt, the conveyor belt is driven to roll, thereby conveying the object to be tested 03.

[0101] In one embodiment, the third image acquisition component 7 is positioned at a second shooting position corresponding to the second platform component 6 in the support direction of the object to be tested 03. The second shooting position is in front of the object to be tested 03 in the conveying direction. The first platform component 1 is provided with a positioning component 10 behind the object to be tested 03 in the conveying direction. The positioning component 10 is used to move the object to be tested 03 to a preset direction.

[0102] There are two positioning components 10, one belonging to the first table assembly 1 and the other to the second table assembly 6. The positioning component 10 is used to reposition the object to be inspected 03 after it enters the second table assembly 6 from the first table assembly 1, particularly after rotation by the rotating component 62 (described below). The positioning component 10 can be positioned in front of the fourth single-axis assembly 63 in the conveying direction of the object to be inspected 03. The structure of the positioning component 10 of the second table assembly 6 is as described in the previous embodiment and will not be repeated here. The difference is that the positioning mechanism base plate 101 of the positioning component 10 of the second table assembly 6 is fixed to the second mounting base plate 75.

[0103] In one embodiment, the second platform assembly 6 further includes a third light assembly 61. The conveyor belt is used to support the object to be tested 03 in the first direction. The third light assembly 61 and the third image acquisition unit 7 are correspondingly arranged in the first direction. The light from the third light assembly 61 is used to project onto the object to be tested 03 between two adjacent second conveyor assemblies.

[0104] The third optical component 61 and the third image acquisition unit 7 are both located between the fourth single-axis component 63 and the fifth single-axis component 64. By setting the third optical component 61 to correspond with the third image acquisition unit 7, when the third image acquisition unit 7 acquires an image, the third optical component 61 provides supplementary lighting, which can realize the acquisition of defects under illumination conditions. Through other optical devices in the following embodiments, it is possible to acquire images of the object to be inspected 03 under different illumination conditions.

[0105] like Figure 15 As shown, the third light component 61 includes two third light source modules, which are arranged opposite each other on both sides of the object to be detected 03 in the second direction. This achieves symmetrical light supply to the object to be detected 03.

[0106] The third light source module includes at least two third light sources. Different third light sources are used to project light at different angles onto the object to be detected 03, which can increase the diversity of illumination.

[0107] The specific form of the first light source can be set as needed, such as at least two third light sources including a third strip light source 611 and a fourth strip light source 612. The third strip light source 611 is perpendicular to the transmission direction of the object to be detected 03, and the light from the fourth strip light source 612 is set at a preset angle to the light from the third strip light source 611. The third strip light source 611 and the fourth strip light source 612 are used to project third strip light onto the object to be detected 03.

[0108] In one embodiment, the third light component 61 further includes a universal support frame assembly and a third support frame assembly. The third strip light source 611 is connected to the universal support frame assembly, and the fourth strip light source 612 is connected to the third support frame assembly. The universal support frame assembly is used to adjust the position of the third strip light source 611 in at least three mutually perpendicular directions, and the third support frame assembly is used to adjust the angle of the fourth strip light source 612 at least.

[0109] The structure of the universal support frame assembly is as described above. Figure 15 As shown, the third support frame assembly includes a third light source connector 613, a seventh adapter 614, and an eighth adapter 615. A fourth strip light source 612 is connected to the third light source connector 613. The third light source connector 613 is connected to the seventh adapter 614 and its position is adjustable in the horizontal direction. The seventh adapter 614 is connected to the eighth adapter 615 and its position is adjustable in the second direction. The ninth adapter 616 is used to adjust the position in the third direction.

[0110] In one embodiment, the second platform assembly 6 further includes two rotating components 62. The third image acquisition unit 7 has a second imaging position corresponding to the second platform assembly 6 in the support direction of the object to be inspected 03. This second imaging position is in front of the object to be inspected 03 in the conveying direction. One of the two rotating components 62 is disposed behind the object to be inspected 03 in the conveying direction, and the other of the two rotating components 62 is disposed behind the object to be inspected 03 in the conveying direction. The rotating component 62 is used to contact and rotate the object to be inspected 03.

[0111] One of the two rotating components 62 is located before the fourth single-axis component 63 in the conveying direction of the object to be tested 03, and the first platform component 1 is located behind the object to be tested 03 in the conveying direction. The other of the two rotating components 62 corresponds to the fifth single-axis component 64 and the third dual-axis component 65 in the conveying direction of the object to be tested 03.

[0112] After the object to be tested 03 enters the second platform component 6, it is rotated 90 degrees by the rotating component 62, and then the third image acquisition component 7 acquires an image of the rotated object to be tested 03. Then the object to be tested 03 moves backward, is rotated 90 degrees by another rotating component 62 and returns to its original position, and then proceeds to the next operation.

[0113] In one implementation, such as Figure 16 As shown, the rotating assembly 62 includes a suction cup 621, a suction cup support, a lifting block 625, a rotating power component 626, a lifting power component 628, a lifting bracket, and a positioning detection component. The suction cup 621 is connected to the suction cup support and is positioned relative to the object to be tested 03. The rotating power component 626 is connected to the lifting block 625, and its output end is connected to the suction cup support, driving the suction cup support to rotate. The lifting block 625 is connected to the lifting power component 628, which is connected to the lifting bracket. The lifting power component 628 drives the lifting block 625 to rise and fall. A positioning detection component is connected to the lifting bracket to detect the rising and falling position of the lifting block 625. When the lifting block 625 rises to the point where the positioning detection component sends a signal, it indicates that the suction cup 621 has attracted the object to be tested 03, and then the rising can stop. The rotating power component 626 is then controlled to drive the suction cup support to rotate, thus rotating the object to be tested 03.

[0114] In a more specific embodiment, the suction cup support includes a suction cup connecting plate 622, a first suction cup fixing block 623, and a second suction cup fixing block 624. The suction cup connecting plate 622 fixes the suction cup 621. The first suction cup fixing block 623 is connected to the suction cup connecting plate 622, and the second suction cup fixing block 624 is connected to the first suction cup fixing block 623 and passes through the lifting block 625, and is connected to the rotating power component 626. The rotating power component 626 can be a motor. A rotary joint 627 is connected to the rotating power component 626 for connecting to an external control terminal. The lifting power component 628 can be a cylinder, and an air pipe connector 629 is connected to the cylinder for connecting to an external air supply device. The lifting support includes a rotating support plate 6210, a mounting plate 6212, and a limiting block 6211. The rotating support plate 6210 and the mounting plate 6212 are vertically arranged and connected to the lifting power component 628. The mounting plate 6212 is horizontally arranged and connected to the second mounting base plate 75. The limiting block 6211 is located between the rotating support plate 6210 and the lifting block 625. The limiting block 6211 is connected to the rotating support plate 6210 and slidably connected to the lifting block 625 to make the movement of the lifting block 625 more stable. The positioning detection component includes a contact 6214 and a positioning trigger 6215. The contact 6214 is fixed on the lifting block 625, and the positioning trigger 6215 is fixed on the mounting plate 6212. The positioning trigger 6215 can be a photoelectric sensor, and the contact 6214 can be a light-shielding plate. In some embodiments, the rotating component 62 includes a buffer 6213, which is used to buffer the rotating component 62.

[0115] In one embodiment, the second table assembly 6 further includes at least one second detection element 71, which is disposed between multiple conveying assemblies and is used to detect the position of the object to be tested 03.

[0116] The first detection element 28 can be of various types, such as a flat switch assembly. The position of the object to be detected 03 can be determined by the second detection element 71, thereby determining whether to activate the third image acquisition element 7 for capturing images, whether to activate the positioning component 10 for positioning, and whether to activate the rotating component 62.
