Detailed Implementation

[0046] The automated detection device and method proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structures. In particular, different proportions may be used in different drawings to illustrate different aspects.

[0047] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish similar objects in order to describe embodiments of the invention, and are not used to describe a specific order or sequence. It should be understood that such uses of terminology are interchangeable where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0048] This embodiment provides an automated detection device, such as... Figure 1The diagram shows an automated inspection device 100 according to one embodiment of the present invention. The automated inspection device 100 includes a conveying mechanism 1 for conveying sheet metal. The conveying mechanism 1 is a conveyor line connected by different areas, including an information confirmation area 10, a buffer area 20, a test area 30, and a convergence area 40. The information confirmation area 10 is used to confirm sheet metal information. When a sheet metal is conveyed to the information confirmation area 10, the sheet metal information is scanned to determine whether the sheet metal needs to be inspected. Sheets requiring inspection are then transported via the conveying mechanism 1 to the test area 30 or the buffer area 20. A handling mechanism 2 transfers the sheet metal to be inspected from the test area 30 to the inspection mechanism 3 for inspection. Based on the inspection results of the inspection mechanism 3, the handling mechanism 2 moves the qualified sheet metal from the inspection mechanism to the convergence area 40, thus returning the qualified sheet metal to the conveying mechanism 1. During this process, sheet metal that does not require inspection continues to be conveyed normally on the conveyor line of the conveying mechanism 1. Without affecting the operation of the sheet metal, the sheet metal detection information is automatically confirmed through the information confirmation area 10. It works in conjunction with the handling mechanism 2 and the detection mechanism 3 to automatically detect the sheet metal. The qualified sheet metal is returned to the conveyor line of the conveyor mechanism 1, and the unqualified sheet metal is automatically screened out of the line. This increases the degree of automation and achieves efficient and rapid sampling tests, effectively improving processing efficiency.

[0049] Furthermore, the detection mechanism 3 and the conveying mechanism 2 are independent of the conveying mechanism 1. The detection mechanism 3 is located on one side of the conveying mechanism 1. In this embodiment, as shown... Figure 1 As shown, the conveying mechanism 2 is located between the conveying mechanism 1 and the detection mechanism 3. The conveying mechanism 2 includes a movable robotic arm 22 and a gripping component 21 at the front end of the robotic arm 22. The gripping component 21 is used to grip the test material in the test area 30 and to grip the tested material to the confluence area 40 or the storage mechanism 4. The fact that the conveying mechanism 2 is located between the conveying mechanism 1 and the detection mechanism 3 is more conducive to the movement of the robotic arm to grip and release materials, and it has more advantages in terms of space. In other embodiments, the conveying mechanism 2 can also be located on the side of the detection mechanism 3 away from the conveying mechanism 1. The positional relationship between the conveying mechanism, the detection mechanism and the conveying mechanism is not specifically limited.

[0050] like Figure 5As shown, the automated inspection device also includes a storage mechanism 4, which stores the boards that fail the inspection by the inspection mechanism 3. The non-conforming boards are placed in storage positions 410, which are inclined in a V-shape on both sides to stably hold them for manual confirmation. In this embodiment, the storage mechanism 4 is located between the inspection mechanism 3 and the conveying mechanism 1, and in front of the robotic arm 22 of the handling mechanism 2. This facilitates the gripping component 21 to directly place the non-conforming boards into the storage mechanism 4, resulting in a more rational spatial layout and a more compact arrangement between the mechanisms, saving space by occupying less usable area. Additionally, a certain amount of space is left on one side of the storage mechanism 4 to facilitate the staff's confirmation and retrieval of the non-conforming boards.

[0051] Specifically, during the inspection of the sheet metal to be tested by the automated inspection device 100, sheet metal that does not require inspection, as identified by the information confirmation area 10, continues to run on the conveyor mechanism 1. Sampling inspection of the sheet metal to be tested does not affect the conveying of sheet metal that does not require inspection, and does not reduce the conveying efficiency of the conveyor mechanism 1. Figure 2 A schematic diagram of the structure of information confirmation area 10 and cache area 20, as shown below. Figure 2 As shown, the information confirmation area 10 includes a first identification component 101, which is located at the rear end of the information confirmation area 10 and above the conveyor wheel. The first identification component 101 is used to scan and identify the horizontally conveyed sheet material from above. The information confirmation area 10 also includes a first drive component 102 and an information confirmation area conveyor wheel 103. The first drive component 102 is located on the side of the conveyor wheel 103 and can independently control the start and stop of the information confirmation area conveyor wheel 103. When the first identification component 101 detects that the sheet material has reached the information confirmation area 10, it controls the first drive component 102 to stop the information confirmation area conveyor wheel 103 from rotating, pausing the sheet material below the first identification component 101. After the first identification component 101 completes its identification, the first drive component 102 then controls the conveyor wheel 103 to run, moving the sheet material to the next workstation. When the next sheet material is transported to the area below the first identification component 101, the first identification component 101 and the conveyor wheel 103 work together to control each sheet material to pause briefly below the first identification component 101 to identify whether it is a sample sheet material (sheet material to be tested), and so on.

[0052] The control of stopping the sheet metal below the first identification component 101 is not limited to the method of identifying the sheet metal by the first identification component 101. It can also be achieved by controlling the start and stop of the conveyor wheel 103 according to the running speed and running time of each sheet metal. When the conveyor wheel 103 stops, the sheet metal can stop exactly below the first identification component 101. Alternatively, a first stop member can be provided in the information confirmation area 10. The first stop member is detachably mounted on the conveyor support of the conveying mechanism 1. When a sheet metal is detected or calculated by the software to have run to the information confirmation area 10, the first stop member rises and stops the sheet metal below the first identification component 101. At the same time, the operation of the conveyor wheel 103 is paused. The first identification component 101 performs information identification on the sheet metal. After the identification is completed, the first stop member descends below the conveyor wheel, and the conveyor wheel 103 restarts, driving the identified sheet metal into the next work station.

[0053] Furthermore, in order for the first identification component 101 to accurately identify the QR code information of the board material, the information confirmation area also includes a first correction component. The first correction component is used to correct the position of the board material conveyed to the information confirmation area. When the first driving component 102 drives the conveying wheel 103 to stop moving and pauses the board material below the first identification component 101, the first correction component corrects the position of the stopped board material. At this time, the scanning range of the camera of the first identification component 101 can scan the QR code information of the board material. The scanning result shows whether the board material needs to be detected or not, thus quickly and accurately identifying the board material information and improving the overall detection efficiency.

[0054] The information confirmation area 10 also includes an ion air device 104, which is located at the front end of the information confirmation area 10. When the board material passes through the information confirmation area, it first passes through the ion air device 104 to eliminate static electricity. After the static electricity is eliminated, it is conveyed by the conveyor wheel 103 to the bottom of the first identification component 101 to identify the board material information. The first driving component drives the conveyor wheel 103 to stop, the first alignment component aligns the board, the barcode is scanned and the result is displayed. The information confirmation is completed, and the conveyor wheel 103 conveys the board material to the next station.

[0055] After the board material is identified by the information confirmation area 10, it is conveyed to the buffer area 20 via the conveyor wheel 103. The conveyor wheel 203 of the buffer area 20 and the conveyor wheel 103 of the information confirmation area 10 are parallel and abut against each other, which can smoothly convey the board material from the information confirmation area 10 to the buffer area 20. The buffer area 20 is used to buffer multiple sets of boards to be tested. The buffer area 20 includes a buffer rack 201. The buffer rack 201 is a multi-layer board structure that can be raised and lowered on the conveyor support of the buffer area 20. The buffer rack 201 is a multi-layer board structure, and each layer can hold one board material to be tested. Whenever there is a board to be tested in the test area 30 and the information confirmation area 10 identifies that there is a board material to be tested waiting to be tested, multiple sets of boards to be tested are temporarily stored in the buffer rack 201. When there is no board material to be tested in the test area 30, the buffer rack 201 lowers to a set of boards to be tested onto the conveyor wheel 203 of the buffer area 20, and the conveyor wheel 203 conveys the board material to be tested to the test area 30.

[0056] In this embodiment, the buffer rack 201 is used to stack the boards to be tested. Initially, the top layer of the buffer rack 201 is flush with the conveyor wheel 203 of the buffer area 20. When the information confirmation area 10 identifies that there are boards to be tested, it controls the board to be tested to stop running at the top layer position of the buffer rack 201. After it is in place, it controls the buffer rack 201 to rise one layer, so that the next empty layer is flush with the conveyor wheel 203 to facilitate the conveying of normal boards (non-boards to be tested). If there are multiple boards to be tested, it controls each board to be tested to pause at the position of the buffer rack 201. After a group of boards to be tested is stored on the buffer rack 201, it controls the buffer rack to rise one layer until all boards to be tested are stored on the buffer rack 201. During this period, if the test board material on the test area 20 is transferred to the testing mechanism 3 by the handling mechanism 2, there will be no test board material in the test area 20. The buffer rack 201 will then descend one position and transfer the bottom layer of test board material to the test area to wait for the handling mechanism 2 to transfer it to the testing mechanism 3 for testing, thereby moving the buffered test board material to the testing area 30.

[0057] Specifically, the buffer area 20 also includes a second stop 202 and a second drive 204. The second stop 202 is retractably mounted on one side of the buffer rack 201, and the second drive 204 controls the start and stop of the conveyor wheel 203 of the buffer area 20. The second stop 202 and the second drive 204 can cooperate to pause the board to be tested above the shelf of the buffer rack 201. In order to stop the board to be tested precisely on the buffer rack 201, a liftable second stop 202 is provided on the outer side of the conveying direction side of the buffer rack 201. If the board is a continuously sampled board, it is necessary to buffer the board to be tested. The second stop 202 is raised to stop the board to be tested on the buffer rack 201, and the second drive 204 controls the conveyor wheel 203 of the buffer area 20 to stop transmission, pausing the board to be tested on the shelf of the buffer rack 201. When the buffer rack 201 is raised, the board is temporarily buffered on the buffer rack 201. After the board to be tested is buffered on the buffer rack 201, the second stop 202 descends below the conveyor wheel 203. The conveyor wheel 203 continues to rotate, without affecting the normal flow of boards. Boards that do not need to be tested will be normally conveyed to the next station from below the boards buffered on the buffer rack 201, that is, on the conveyor wheel 203. When there are no boards to be tested in the testing area 30, the buffer rack moves to the next layer, places the board to be tested on the conveyor wheel 203, and moves it to the next station with the conveyor wheel 203.

[0058] When the board to be tested is the first board to be tested, it does not need to be stored in the buffer area 20. It is directly conveyed to the testing area 30 via the conveyor wheel 203. The testing area 30 includes a lifting platform 301 with a horizontal bearing surface for supporting the board to be tested. The bearing surface has an opening corresponding to the conveyor wheel 303, through which the conveyor wheel 303 can pass. The lifting platform 301 is vertically adjustable within the testing area 30. When there is no board to be tested, the lifting platform 301 lowers until the bearing surface is below the conveyor wheel 303, allowing normal boards to be conveyed normally on the conveyor wheel 303 above the bearing surface. When a board to be tested needs to be tested, the lifting platform 301 rises to support it, and the conveyor wheel 303 is below the bearing surface, allowing normal boards that do not require testing to be conveyed normally.

[0059] To ensure that the sheet material to be tested stops precisely above the lifting platform 301, the testing area 30 also includes a third stop 304 and a third drive 305. The third stop 304 is vertically mounted on the support of the testing area 30 and located on one side of the conveying direction of the lifting platform 301. The third drive 305 is used to control the start and stop of the conveying wheel 303 of the testing area. The third stop 304 and the third drive 305 can cooperate to pause the sheet material to be tested above the bearing surface of the lifting platform 301. When a piece of material to be tested moves to the lifting platform 301, the third stop 304 rises to stop the material above the lifting platform 301. The third drive 305 controls the conveyor wheel 303 of the test area 30 to stop running. At this time, the material to be tested is paused on the lifting platform 301. The lifting platform 301 rises to lift the material to be tested. The third stop 304 descends to below the conveyor wheel 303. The conveyor wheel 303 resumes operation and continues to run to the normal material in the test area 30.

[0060] After the board to be tested is lifted by the lifting platform 301, the conveying mechanism 2, located on one side of the conveying mechanism 1, picks up the board to be tested from the lifting platform 301 using the suction component 21. The board to be tested is then placed on the testing mechanism 3 for testing. After the testing is completed, the tested board is picked up and placed in the corresponding position. To ensure that the suction component 21 can just grab the board to be tested after the conveying mechanism 2 moves to the conveying area, the testing area 30 also includes a second alignment component. The second alignment component is used to align the position of the board on the lifting platform 301, so that the conveying mechanism 2 can just pick up the aligned board. This prevents the board from being poorly positioned, which could lead to insecure gripping and the risk of the board falling and being damaged.

[0061] Specifically, after the sheet material to be tested on the lifting platform 301 is picked up by the conveying mechanism 2, the lifting platform 301 descends to its initial position, below the conveyor wheel 303. When the next sheet material to be tested reaches the lifting platform 301, the third stop 304 and the third drive 305 work together to stop the sheet material to be tested again on the bearing surface of the lifting platform 301. The lifting platform 301 rises, the third stop 304 retracts, and the conveyor wheel 303 runs, and this process continues. When the lifting platform 301 descends to its initial position, the buffer area 20 receives a signal and lowers the buffer rack 201 by one level to release a sheet material to be tested. The conveyor wheel transports the sheet material to be tested to the bearing surface of the lifting platform 301, which then rises to await the robotic arm 22 to grab it, forming a complete inspection and transport chain. Without affecting the normal sheet material transportation, the sheet materials to be tested are randomly inspected, and the inspected sheet materials are classified according to the inspection results. According to the test results of the testing agency 3, the boards are classified as qualified boards and unqualified boards. The handling agency 2 puts the qualified boards back into the conveying agency 1, while the unqualified boards are placed in the storage agency 4 for staff to confirm. After the classification and placement are completed, the robotic arm of the handling agency 2 picks up and tests the next board.

[0062] Specifically, the handling mechanism 2 returns the qualified sheet metal to the confluence area 40 of the conveying mechanism 1. The confluence area 40 is located at the rear end of the testing area 30. The confluence area 40 includes a confluence conveyor wheel 403, a second identification component 401, and a confluence conveyor position 402. The confluence conveyor position 402 is adjacent to the conveyor wheel 303 and is located at the rear end of the lifting platform 301. The conveyor wheel 403 is located below the confluence conveyor position 402. The second identification component 401 is located at the rear end of the confluence conveyor position 402 and is used to identify and confirm all the sheet metal running on the conveying mechanism 1 after confluence, including the qualified sheet metal. In this embodiment, the second identification component 401 is mounted above the conveying mechanism 1 by a bracket. When the sheet metal is conveyed to the area below the second identification component 401 by the conveyor wheel 403, the barcode information of the conveyed sheet metal is scanned and identified. The identification information is transmitted to the system so that the operator can know the information of all the sheet metals finally conveyed. The boards conveyed through the confluence area 40 will continue to be conveyed to the next station, where they will be sampled and inspected in the automated inspection device. The qualified boards will then be automatically re-converged to the conveying mechanism, which greatly improves inspection efficiency, inspection accuracy and product qualification rate. It also improves factory efficiency and solves the problem of low efficiency caused by the difference in the number of boards sampled from different batches.

[0063] In this embodiment, the inspection mechanism 3 is a visual inspection device, which includes a support platform, support beams, crossbeams, and an inspection platform. Support beams are provided on opposite sides of the support platform along a first direction, and the crossbeams are mounted on the support beams along a second direction. The visual inspection device includes an image acquisition mechanism positioned opposite each other along a third direction. The image acquisition mechanism can acquire images of the sheet material to be inspected on the inspection platform, check and analyze product quality, and output inspection results. Based on the inspection results, a handling mechanism identifies and selectively transports the sheet material to the corresponding position.

[0064] In this embodiment, the information confirmation area 10, buffer area 20, detection area 30, and convergence area 40 are arranged sequentially on the transmission path. It should be noted that the relative positions of the information confirmation area 10, buffer area 20, detection area 30, and convergence area 40 can be changed according to different device structures and different transmission methods, and no specific restrictions are imposed here.

[0065] This invention also provides a detection method for an automated detection device. The automated detection device includes a conveying mechanism 1, a detection mechanism 3, a handling mechanism 2, and a storage mechanism 4. The conveying mechanism 1 includes an information confirmation area 10, a buffer area 20, a test area 30, and a convergence area 40 arranged sequentially along the conveying path. The detection method involves sampling inspection of the entire batch of boards in the conveying mechanism 1. It can efficiently remove the boards that need to be randomly sampled from the production line without affecting normal board processing, conduct inspection, and then return them to the production line for the next process. This achieves fully automated detection, eliminating the need for manual sampling inspection after the entire batch of boards has been processed from the production line, thus improving operational efficiency.

[0066] The detection method includes: identifying sheet material information;

[0067] According to the sheet material information, the sheet material to be inspected is transferred to the inspection mechanism 3, while the sheet material that does not need to be inspected is continuously conveyed on the conveying mechanism.

[0068] Based on the test results from the testing organization, the tested sheet material is transferred to the confluence area 40 or the storage organization 4.

[0069] Specifically, when the sheet material is conveyed on the automated inspection device 100, it first passes through the information confirmation area 10 of the conveying mechanism 1. The information confirmation area 10 includes an ion air device 104 and a first identification component 101. Whenever a sheet material runs to the information confirmation area 10 during the conveying operation of the conveyor wheel, the ion air device 104 is first controlled to eliminate static electricity from the sheet material. The sheet material is then transported by the conveyor wheel 103 to below the first identification component 101. After the system recognizes the arrival signal of the sheet material, it controls the sheet material to pause and return to the identification area below the first identification component 101. The first identification component 101 scans and identifies the QR code information of the drilled holes in the sheet material. The scanning result is confirmed, and a buffer mechanism or a detection mechanism is selected based on the scanning result. After the information confirmation is completed, the conveyor wheel 103 in the information confirmation area 10 is controlled to resume operation and transport the sheet material to the next workstation.

[0070] Furthermore, the arrival signal of the sheet material can be identified by the first identification component 101, or the start and stop of the conveyor wheel 103 can be controlled by image capture or calculation of the running speed and time of each sheet material to pause the sheet material below the first identification component 101.

[0071] In this embodiment, the process of pausing and correcting the sheet material within the recognition area below the first recognition component 101 includes: the control information confirmation area conveyor wheel 103 stopping rotation, and the first correction component correcting the sheet material position; after the first recognition component 101 recognizes the sheet material information, the information confirmation area conveyor wheel 103 resumes rotation, transporting the sheet material to the next workstation, and similarly driving the next sheet material to the recognition area below the first recognition component 101.

[0072] Specifically, the scanning result shows whether the board needs to be inspected or not. Regardless of the inspection result, after the information is confirmed, the first drive unit 102 controls the conveyor wheel 103 to run and transport the board to the next station.

[0073] In this embodiment, the first identification component 101 is located at the rear end of the information confirmation area 10, but is not limited to the rear end of the information confirmation area 10. If the first identification component 101 is located at any position in the information confirmation area 10, and there is sufficient space for the board to run at the rear end of the information confirmation area 10, without controlling the board to pause in the information confirmation area 10, after the first identification component 101 scans and identifies the board information, it can obtain the scanning result during the subsequent operation and run the board to the next station according to the scanning result, which can save the step of pausing at the information confirmation mechanism 10.

[0074] If the board being tested is the first board to be tested, it is not necessary to store the board in the buffer area 20. The conveyor wheel will directly transport the board to be tested to the testing area 30. If the board being tested is not the first board to be tested, it will be moved to the buffer area 20 of the next station for buffering and will be arranged in sequence to wait for transfer and testing.

[0075] When continuous sheet metal is detected and needs to be sampled, and when sheet metal to be tested is detected passing through the test area 30, the second stop 202 of the buffer area 20 is raised to stop the sheet metal at the position of the buffer frame 201. The second drive unit 204 controls the conveyor wheel 203 in the buffer area 20 to stop, and after the sheet metal to be tested is paused on the buffer frame 201, the buffer frame 201 of the buffer area 20 is raised by one layer, and the sheet metal to be tested is raised together with the buffer frame 201. The second stop 202 is lowered and retracted below the conveyor wheel 203, and the conveyor wheel 203 resumes operation below the buffer frame 201 to convey normal sheet metal. If a previous board to be tested is not detected and there are still boards to be tested in the information confirmation area 10 of the production line that need to be sampled, the above method is repeated to control each subsequent board to be tested to be stored separately in each layer of buffer rack 201. That is, after multiple boards to be tested are conveyed and paused above the layers of the buffer rack 201 in the buffer area, the buffer rack 201 is controlled to rise one layer in turn to lift all the boards to be tested separately in each layer of the buffer rack 201. After the previous board to be tested is detected and detected, that is, when there are no boards to be tested in the testing area 30, the buffer rack 201 is controlled to descend one layer to put one group of boards to be tested back to the buffer area conveyor wheel 203 and send them to the next testing area 30. The boards to be tested are then paused above the lifting platform 301, and the lifting platform 301 is controlled to rise. The conveying mechanism 2 picks up the boards to be tested and transfers them to the testing mechanism 3 for testing.

[0076] In this station, the boards to be tested do not affect the normal flow of boards in the buffer area 20, and boards that do not need to be tested flow from below the buffer rack 201 to the next station.

[0077] Furthermore, based on the confirmation of whether the first identification component 101 is the sampled board material information, it is determined whether the board material flowing to the test area 30 is the board material to be tested. If it is the board material to be tested and the board material to be tested is detected passing through the test area 30, the third stop 304 in the test area 30 is controlled to rise, stopping the board material to be tested above the bearing platform of the lifting platform 301. The third drive component 305 drives the conveyor wheel 303 in the test area 30 to stop rotating, stopping the board material to be tested above the bearing surface of the lifting platform 301. Then, the lifting platform 301 is controlled to rise, lifting the board material to be tested. After the board material to be tested is lifted, the third stop 304 is controlled to descend and return to below the conveyor wheel 303, and the conveyor wheel 303 is controlled to resume operation. The resumption of operation of the conveyor wheel 303 will allow the board material that does not need to be tested to flow through the test area 30 to the next station.

[0078] After the sheet material to be tested is lifted from the platform 301, the second alignment component is controlled to align the sheet material, awaiting the gripper 22 to pick it up. If the sheet material does not require sampling inspection, no action is performed at this station, and the sheet material flows to the next station via the running conveyor wheel 303. When the conveying mechanism 2 receives the signal that the platform 301 has been lifted, it is controlled to move to the conveying area. The gripper 22 moves above the platform 301, picks up the sheet material to be tested from above the platform 301, and moves it to the testing mechanism 3 for testing and outputting the test results.

[0079] If the test result is qualified, the handling mechanism 2 moves to the handling area, the robot arm 22 moves to the testing mechanism 3, picks up the qualified sheet material after testing and puts it into the confluence area 40 according to the signal, and then the robot arm 22 performs the next sheet material picking and testing step.

[0080] If the test result is unqualified, the handling mechanism 2 moves to the handling area, and the robot arm 22 moves to the testing mechanism 3. It picks up the unqualified board material after the test is completed and puts it into the storage mechanism 4 according to the signal, waiting for manual confirmation. The robot arm then performs the same picking and testing steps for one board material.

[0081] After the robotic arm 22 picks up qualified sheet metal and flows it into the confluence area 40, all sheet metal flowing through the confluence area 40 at this time are either qualified or do not require inspection. The second identification component 401 then scans and confirms the QR code information of all sheet metal in the confluence area and transports the sheet metal to the next workstation. Without affecting the normal conveying of sheet metal, the automated inspection device filters out unqualified sheet metal, achieving highly efficient automated operation, improving inspection efficiency, and saving labor costs.

[0082] The automated inspection equipment of the present invention, by adding inspection equipment to the conveyor belt of the conveyor mechanism 1 and cooperating with the automated inspection control terminals of each area, automatically and accurately completes the inspection of the sheet metal during the sheet metal operation. Specifically, it is manifested as follows:

[0083] 1. Visual inspection is added during the material conveying process. The material to be inspected is completed during the normal operation of each workstation without affecting the normal operation of other materials. This achieves fully automated identification, inspection and handling, and improves the degree of automation and inspection efficiency.

[0084] 2. A cache area is set up in the back end of the information confirmation area to realize the pre-inspection material change cache during the normal transfer of sheet materials. The batch of sheet materials that need to be inspected and the sampling boards that cannot be immediately sampled are cached. Similarly, the diversion is realized without affecting the normal transfer of the production line, and the inspection of each sampling board is automatically completed by releasing the sampling boards one by one.

[0085] 3. A liftable detection position is set up. The first identification component identifies whether it is a board material to be inspected. If it is a sampled board material, when the sampled board material is conveyed to the top of the lifting platform, the lifting platform will lift the sampled board material and grab it by the robotic arm without affecting the normal operation of the production line. The material is diverted at the grabbing platform, which efficiently processes the board material that needs to be sampled without affecting the operation of the overall production line.
