Description

Technical Field

[0001] This application relates to the field of testing technology, and in particular to a vertical testing device. Background Technology

[0002] Currently, in inspection equipment, vision inspection systems using devices such as cameras are commonly used to inspect the workpieces. For sheet metal workpieces, horizontal inspection equipment is typically used for double-sided inspection.

[0003] For example, PCB board inspection items include, but are not limited to, appearance defects (such as scratches, dents, and warping) and circuit pattern defects (open circuits, short circuits, and gaps). In the industry, PCB board inspection equipment is mainly divided into offline single-station double-sided inspection equipment, online double-station double-sided inspection equipment, and online single-station double-sided inspection equipment. All three types of inspection equipment are based on the PCB board being in a horizontal position. Typically, a PCB board has two sides, A and B, requiring double-sided inspection. However, due to the limitations of current horizontal inspection methods, there are still issues such as turnover losses, redundant inspection processes, and the adhesion of foreign matter, leading to problems such as low inspection efficiency and unstable inspection accuracy. Furthermore, horizontal inspection equipment, based on the requirement of double-sided PCB inspection, often suffers from drawbacks such as large size and high maintenance difficulty. For example, offline single-station double-sided inspection equipment requires manual flipping of the board to achieve double-sided inspection. Flipping actions not only easily cause scratches on the PCB surface, increasing the PCB loss rate, but also, being independent of the inspection process, consume extra time and reduce overall inspection efficiency. While online dual-station double-sided inspection equipment uses automated processes to replace manual labor, reducing labor costs, it still suffers from low inspection efficiency and turnover losses due to flipping actions. Furthermore, this type of dual-station double-sided inspection equipment is bulky, has low space utilization, and high equipment costs. Although online single-station double-sided inspection equipment does not require flipping actions, it necessitates setting up a vision module below the PCB inspection station. During long-term inspection, foreign objects can easily remain on both the PCB support platform and the vision module below the PCB inspection station, affecting image quality.

[0004] In summary, traditional testing equipment in the industry suffers from problems such as low testing efficiency, large space occupation, foreign matter residue affecting testing accuracy, and high equipment cost. There is a need for a vertical testing device that can solve these problems. Summary of the Invention Therefore, it is necessary to provide a vertical testing device, the specific technical solution of which is as follows.

[0005] A vertical testing device, comprising: The detection clamping module includes two clamping components arranged opposite each other along a vertical plane and a distance adjustment component; the distance adjustment component is connected to at least one clamping component and is used to adjust the distance between the two clamping components so that the two clamping components respectively abut against the two sides of the workpiece being tested and the workpiece being tested is arranged vertically. The vision module includes a front vision component and a back vision component respectively arranged on both sides of the detection clamping module.

[0006] Furthermore, the clamping assembly includes a frame, a clamping component, and a straightening plate; the clamping component is connected to the frame and is used to clamp the workpiece to be tested; the straightening plate is connected to the frame, the straightening plate is arranged vertically and fits against the surface of the workpiece to be tested, and the straightening plate is transparent.

[0007] Furthermore, the elastic clamping component is located above the straightening plate.

[0008] Furthermore, at least one clamping assembly is provided with an elastic clamping component; the elastic clamping component includes a pressure plate and an elastic element; the elastic element is connected to the pressure plate and the frame respectively; when the test piece is not clamped, the pressure plate extends outward from the surface of the second correction plate.

[0009] Furthermore, one clamping assembly is connected to a plurality of elastic clamping components, and another clamping assembly is connected to a plurality of fixed clamping components; the plurality of elastic clamping components are arranged at intervals, so that a first gap is formed between adjacent elastic clamping components; the plurality of fixed clamping components are respectively arranged opposite to the plurality of elastic clamping components.

[0010] Furthermore, the distance adjustment component is connected to one of the clamping components, so that one set of clamping components remains fixed, while the other set of clamping components moves relative to the first clamping component under the action of the distance adjustment component.

[0011] Furthermore, the front vision component includes a front left detection camera, a front right detection camera, and a positioning camera; the front left detection camera is connected to a first three-axis module, and the front right detection camera is connected to a second three-axis module; the back vision component includes a back left detection camera and a back right detection camera, the back left detection camera is connected to a third three-axis module, and the back right detection camera is connected to a fourth three-axis detection module.

[0012] Furthermore, it also includes a loading / unloading module, which is located above the detection and clamping module; the loading / unloading module includes a loading component and an unloading component, the loading component is located at one end of the detection and clamping module, and the unloading component is located at the other end of the detection and clamping module.

[0013] Furthermore, the feeding assembly includes a feeding clamp, a feeding X-axis moving module, a feeding Y-axis moving module, and a feeding Z-axis moving module; the feeding clamp is connected to the feeding Z-axis moving module, the feeding Z-axis moving module is connected to the feeding Y-axis moving module, and the feeding Y-axis moving module is connected to the feeding X-axis moving module; the feeding assembly, the detection and clamping module, and the unloading assembly are arranged along the moving direction of the feeding X-axis moving module.

[0014] Furthermore, the feeding clamp is provided with multiple clamping teeth, which are arranged at intervals to form a second gap between adjacent clamping teeth.

[0015] Beneficial effects: 1. The vertical inspection device provided by this invention keeps the workpiece in a vertical position during the inspection process. Front vision components and back vision components are arranged on both sides of the inspection clamping module, respectively, to achieve simultaneous double-sided inspection at a single station. The simultaneous double-sided inspection mode eliminates the flipping action, optimizes the inspection process, improves inspection efficiency, avoids board surface damage caused by flipping, and thus improves inspection accuracy and stability. The single-station inspection mode reduces space occupation, improves space utilization, and reduces equipment costs. Furthermore, foreign objects are less likely to remain on the vertically arranged workpiece, vision module, and clamping components, avoiding the influence of foreign objects on image quality, thereby improving precision measurement accuracy and avoiding false detections.

[0016] 2. The vertical inspection device provided by this invention mainly uses elastic clamping components and fixed clamping components to clamp the edge of the workpiece during loading and unloading. During the inspection process, a straightening plate assists in clamping the workpiece. On the one hand, by clamping the edge of the workpiece for loading and unloading, and only clamping the edge for vertical loading and unloading, friction on the surface of the workpiece can be minimized during the turnover, thereby avoiding wear on the surface of the workpiece. On the other hand, by using the straightening plate to assist in clamping the workpiece, the stability of clamping can be improved, avoiding the workpiece from swaying, shaking, or even falling, thus improving the stability of the inspection. At the same time, the straightening plate can also correct the flatness of the workpiece, improving the accuracy of the inspection.

[0017] 3. The vertical testing device provided by the present invention, when the clamping assembly clamps the workpiece under the action of the distance adjustment assembly, the pressure plate first contacts the workpiece to achieve initial clamping, ensuring the stability of the workpiece; under the action of the elastic member, the workpiece will not shift due to external force, avoiding affecting the testing accuracy; the elastic clamping component and the fixed clamping component are used as the main clamping structure of the workpiece to avoid the straightening plate being subjected to concentrated force, resulting in scratches or even cracks.

[0018] 4. The vertical inspection device provided by the present invention adopts two sets of vision components, one for the front and one for the back. Each set of vision components includes two independent inspection mechanisms for the left and right sides to perform simultaneous inspection of the front and back sides and simultaneous inspection of the left and right sides, which greatly improves the inspection efficiency.

[0028] Example Reference Figure 1 As shown, this embodiment provides a vertical inspection device, including an inspection clamping module 1 and a vision module 2. It should be noted that the vertical inspection device provided in this embodiment is applicable to board-type components to be inspected, including but not limited to PCB boards. In this embodiment, a PCB board is used as the component to be inspected. The inspection clamping module 1 is used to clamp the PCB board during the inspection process, and the vision module 2 is used to inspect the PCB board.

[0029] Specifically, refer to Figure 2 As shown, the detection clamping module 1 includes two clamping components arranged opposite each other along a vertical plane and a distance adjustment component 13. The distance adjustment component 13 is connected to at least one clamping component and is used to adjust the distance between the two clamping components. In this embodiment, the distance adjustment component 13 is connected to only one clamping component, that is, the two clamping components are divided into a fixed clamping component 11 and a movable clamping component 12. During the detection operation, the fixed clamping component 11 remains fixed, and the distance adjustment component 13 is connected to the movable clamping component 12. When clamping or releasing the PCB board, the distance adjustment component 13 drives the movable clamping component 12 to move. In other embodiments, the distance adjustment component 13 can also be connected to each of the two clamping components to drive the two clamping components to move synchronously.

[0030] The two clamping components are arranged opposite each other along the vertical plane, and the two clamping components themselves are also arranged in the vertical direction, so that when the PCB board is clamped, the two clamping components abut against the two sides of the PCB board respectively, and the PCB board is arranged vertically.

[0031] Continue to refer to Figure 1 As shown, the vision module 2 includes a front vision component and a back vision component respectively arranged on both sides of the inspection clamping module 1. Since the PCB board is arranged vertically, when double-sided inspection is required, the front vision component and the back vision component can be arranged on both sides of the inspection clamping module 1 respectively. During double-sided inspection, there is no need to flip the PCB board, optimizing the inspection process, improving inspection efficiency, avoiding board surface damage caused by flipping, and thus improving inspection accuracy and stability. Only the front vision component and the back vision component need to be arranged on both sides of one inspection station, reducing station setup, lowering costs, reducing the space occupied by the inspection equipment, and improving space utilization. Since both the inspection clamping module 1 and the PCB board are arranged vertically, and the front vision component and the back vision component facing the PCB board are arranged facing the inspection clamping module 1, it is difficult for dust and other foreign objects to directly remain on the inspection clamping module 1, the front vision component, and the back vision component, avoiding the impact of residual foreign objects on the image quality, improving inspection accuracy, and avoiding false detections.

[0032] It should be noted that the vertical testing equipment also includes a support platform 4, the fixed clamping component 11 is fixedly installed on the support platform 4, and the movable clamping component 12 is movably installed on the support platform 4; while the distance adjustment component 13 is installed between the movable clamping component 12 and the support platform 4, and is used to drive the movable clamping component 12 to move.

[0033] The vertical inspection device provided in this embodiment keeps the PCB board in a vertical position during the inspection process. Front vision components and back vision components are respectively arranged on both sides of the inspection clamping module 1, realizing simultaneous double-sided inspection at a single station. The simultaneous double-sided inspection mode eliminates the flipping action, optimizes the inspection process, improves inspection efficiency, avoids board surface damage caused by flipping, and thus improves inspection accuracy and stability. The single-station inspection mode reduces space occupation, improves space utilization, and reduces equipment costs. Furthermore, foreign objects are less likely to remain on the vertically arranged PCB board, vision module 2, and clamping components, avoiding the impact of foreign objects on image quality, thereby improving precision measurement accuracy and avoiding false detections.

[0034] Specifically, the clamping assembly includes a frame, clamping components, and a straightening plate. The clamping components are connected to the frame and are used to clamp the PCB board. The straightening plate is connected to the frame, is vertically arranged, and is in contact with the surface of the PCB board; the straightening plate is transparent. The clamping components are located above the straightening plate.

[0035] The clamping components can take many forms; for example, refer to... Figure 2 and Figure 3 As shown, in this embodiment, the clamping components are divided into a fixed clamping component 112 and an elastic clamping component 122. Specifically, the fixed clamping component 11 includes a first frame 111, a fixed clamping component 112, and a first straightening plate 113; the movable clamping component 12 includes a second frame 121, an elastic clamping component 122, and a second straightening plate 123. The fixed clamping component 112 is connected to the first frame 111, and the elastic clamping component 122 is connected to the second frame 121. The fixed clamping component 112 is located above the first straightening plate 113, and the elastic clamping component 122 is located above the second straightening plate 123. The fixed clamping component 112 and the elastic clamping component 122 clamp the edge of the PCB board, where there are no features that need to be detected. During the loading and unloading process, the edges of the PCB board are mainly clamped by the fixed clamping component 112 and the elastic clamping component 122. Only the edges of the PCB board are clamped for vertical loading and unloading. During the turnover process, friction on the PCB board surface can be minimized, thereby avoiding wear on the PCB board surface.

[0036] Reference Figure 4The first correction plate 113 is connected to the first frame 111 via the first fine-tuning component 114, and the second correction plate 123 is connected to the second frame 121 via the second fine-tuning component 124. The first correction plate 113 and the second correction plate 123 are respectively attached to the surfaces of both sides of the PCB board. By using the correction plates to assist in clamping the PCB board, the clamping stability can be improved, and the PCB board can be prevented from swaying, shaking, or even falling off, thereby improving the stability of the detection. At the same time, the correction plates correct defects such as warping of the PCB board, improve the flatness of the PCB board, and thus improve the accuracy of the detection.

[0037] The first correction plate 113 and the second correction plate 123 are both transparent. In this embodiment, the first correction plate 113 and the second correction plate 123 are both glass. In other embodiments, other transparent materials can also be selected as correction plates.

[0038] Specifically, refer to Figure 5 As shown, the second fine-tuning component 124 includes a fine-tuning clamp 1241 and an adjusting screw 1242. The fine-tuning clamp 1241 clamps the second straightening plate 123, and the adjusting screw 1242 connects the fine-tuning clamp 1241 and the second frame 121. The second straightening plate 123 is connected to the second frame 121 through multiple second fine-tuning components 124. By adjusting the position of the adjusting screw 1242 and the fine-tuning clamp 1241, the pitch and yaw of the second straightening plate 123 relative to the mounting surface of the second frame 121 can be adjusted, compensating for the flatness defects of the glass itself and facilitating visual image acquisition. The structure of the first fine-tuning component 114 is the same as that of the second fine-tuning component 124, and will not be described in detail in this embodiment.

[0039] Specifically, refer to Figure 3 As shown, the fixing clamping component 112 is a fixed member that remains fixed with the fixing clamping assembly 11. The end face of the fixing clamping component 112 is flush with the surface of the first straightening plate 113, meaning that when the PCB board abuts against the end face of the fixing clamping component 112, the first straightening plate 113 also adheres to the surface of the PCB board. The elastic clamping component 122 includes a pressure plate 1221 and an elastic element 1222. The elastic element 1222 is connected to the pressure plate 1221 and the second frame 121 respectively. The elastic element 1222 has elastic potential energy to drive the pressure plate 1221 to move away from the second frame 121, so that when the PCB board is not clamped, the pressure plate 1221 extends outward from the surface of the second straightening plate 123. In this embodiment, the elastic element 1222 can be a spring.

[0040] Before testing, the PCB board is first transferred between the fixed clamping assembly 11 and the movable clamping assembly 12 by other handling mechanisms. At this time, the PCB board is in contact with the fixed clamping assembly 112 and the first straightening plate 113. The movable clamping assembly 12 is moved by the distance adjustment assembly 13. At this time, since the pressure plate 1221 extends outward from the surface of the second straightening plate 123, the pressure plate 1221 first contacts the surface of the PCB board for initial clamping, so that the PCB board remains stable. Under the action of the elastic element 1222, the PCB board will not shift due to external force, avoiding affecting the testing accuracy. Part of the external force comes from the straightening plate correcting the warping of the PCB board, and part comes from the friction generated when the other handling mechanisms release the PCB board and withdraw upward after the testing clamping module 1 clamps the PCB board. Using the fixed clamping assembly 112 and the elastic clamping assembly 122 as the main clamping structure of the PCB board avoids the glass straightening plate from being subjected to concentrated force, which could cause scratches or even cracks.

[0041] Specifically, refer to Figure 4 As shown, the movable clamping component 12 moves in the direction of moving away from or towards the fixed clamping component 11, i.e., the Y direction. The movable clamping component 12 can be driven to move towards or away from the fixed clamping component 11 via the distance adjustment component 13. In this embodiment, the distance adjustment component 13 can be a linear module as in the prior art, or other structures can be selected.

[0042] Specifically, continue to refer to Figure 2 As shown, the fixed clamping assembly 11 includes multiple fixed clamping components 112, which are arranged at intervals, specifically along the X-axis, forming a first gap 1121 between adjacent fixed clamping components 112. The movable clamping assembly 12 includes multiple elastic clamping components 122, which are arranged in a one-to-one correspondence with the fixed clamping components 112. By reserving the first gap 1121, when other handling structures transfer PCB boards with the detection clamping module 1, the clamping parts of other handling structures can be inserted into the first gap 1121, facilitating the loading and unloading of PCB boards.

[0043] Specifically, refer to Figure 6As shown, the front vision assembly includes a front left detection camera 21, a front right detection camera 22, and a positioning camera 23. The front left detection camera 21 is connected to a first three-axis module 26, and the front right detection camera 22 is connected to a second three-axis module 27. The three-axis modules can move the detection cameras along the X, Y, and Z axes respectively, thereby detecting different areas. Specifically, the three-axis movement module can adopt a linear movement module structure. Correspondingly, the back vision assembly includes a back left detection camera 24 and a back right detection camera 25. The back left detection camera 24 is connected to a third three-axis module, and the back right detection camera 25 is connected to a fourth three-axis detection module. Using two sets of vision assemblies, each set includes two independent detection mechanisms (left and right) to perform simultaneous inspection of both sides of the PCB board and simultaneous inspection of left and right sections, greatly improving inspection efficiency.

[0044] Specifically, refer to Figure 1 As shown, the vertical testing equipment also includes a loading / unloading module 3, which is mounted on a support frame 33, which is mounted on a support platform 4, so that the loading / unloading module 3 is located above the testing clamping module 1. (Refer to...) Figure 7 As shown, the loading / unloading module 3 includes a loading component 31 and an unloading component 32. The loading component 31 is located at one end of the detection and clamping module 1, and the unloading component 32 is located at the other end of the detection and clamping module 1. When the loading component 31 or the unloading component 32 clamps the PCB board, the PCB board is in a vertically downward position. This ensures that the PCB board remains in a vertically downward position during loading / unloading and detection processes.

[0045] Specifically, refer to Figure 7 and 8 As shown, the feeding assembly 31 includes a feeding clamp 311, a feeding X-axis moving module 312, a feeding Y-axis moving module 313, and a feeding Z-axis moving module 314. The feeding clamp 311 is connected to the feeding Z-axis moving module 314, and the feeding Z-axis moving module 314 drives the feeding clamp 311 to move along the Z-axis direction. The feeding Z-axis moving module 314 is connected to the feeding Y-axis moving module 313, and the feeding Y-axis moving module 313 drives the feeding Z-axis moving module 314 to move along the Y-axis direction. The feeding Y-axis moving module 313 is connected to the feeding X-axis moving module 312, and the feeding X-axis moving module 312 drives the feeding Y-axis moving module 313 to move along the X-axis direction. Thus, the feeding clamp 311 can move in three axes.

[0046] Accordingly, the unloading assembly 32 includes an unloading clamp 321, an unloading X-axis moving module 322, an unloading Y-axis moving module 323, and an unloading Z-axis moving module 324; the unloading clamp 321 is connected to the unloading Z-axis moving module 324, the unloading Z-axis moving module 324 is connected to the unloading Y-axis moving module 323, and the unloading Y-axis moving module 323 is connected to the unloading X-axis moving module 322. All of the aforementioned moving modules can be linear moving modules with guide rails, specifically driven by a motor lead screw, or by a cylinder, hydraulic cylinder, electric rod, etc.

[0047] Three-axis moving modules are used to assist in the loading and unloading process, avoiding direct scraping between PCB boards and structural components and preventing turnover losses.

[0048] During the inspection process, the loading clamp 311 holds the PCB board and transfers it from the loading area to between the fixed clamping component 11 and the movable clamping component 12. After the fixed clamping component 11 and the movable clamping component 12 clamp the PCB board, the loading clamp 311 releases the PCB board. The loading clamp 311 then returns to the loading area to await the next loading. After inspection, the unloading clamp 321 holds the PCB board, and the fixed clamping component 11 and the movable clamping component 12 release the PCB board. The unloading clamp 321 then transfers the PCB board to the unloading area. Before inspection is completed, the unloading clamp 321 can be moved to the inspection clamping module 1 in advance. The loading and unloading actions between the loading component 31 and the unloading component 32 are independent of each other, allowing for simultaneous loading and unloading, minimizing time and improving efficiency.

[0049] Specifically, refer to Figure 9 and Figure 11 As shown, the loading clamp 311 includes a fixed clamp 3111, a movable clamp 3112, and a driving member 3113. The movable clamp 3112 is hinged to the loading clamp 311 via a pin 3114. The driving member 3113 connects the movable clamp 3112 and the fixed clamp 3111. The driving member 3113 drives the movable clamp 3112 to rotate around the axis of the pin 3114, thereby allowing the loading clamp 311 to release or clamp the PCB board. (Refer to...) Figure 10As shown, the fixed clamp 3111 is provided with a plurality of first clamping teeth 3115, which are spaced apart and spaced apart along the X-axis, forming a second gap 3117 between adjacent first clamping teeth 3115; the movable clamp 3112 is provided with a plurality of second clamping teeth 3116, which correspond one-to-one with the first clamping teeth 3115; when transferring the PCB board between the fixed clamp 3111 and the detection clamping module 1, the first clamping teeth 3115 engage with the first gap 1121, and the fixed clamping component 112 engages with the second gap 3117. This ensures that the clamping parts of the loading clamp 311, unloading clamp 321, and clamping component are all at the edge of the PCB board, avoiding interference with the features to be detected. It should be noted that the structure of the unloading clamp 321 is the same as that of the loading clamp 311, and will not be described again in this embodiment.

[0050] Reference Figure 12 As shown, the vertical inspection equipment also includes a lower frame 5, an upper frame 6, an external loading rack 7, and an external unloading rack 8. The support platform 4 is disposed on the lower frame 5, and the upper frame 6 is disposed on the support platform 4 and surrounds the inspection clamping module 1 and the vision module 2, providing protection for the inspection clamping module 1 and the vision module 2; the external loading rack 7 surrounds the loading assembly 31, and the external unloading rack 8 surrounds the unloading assembly 32, supporting the loading and unloading modules 3 and improving the stability of the equipment during operation.

[0051] Specifically, the vertical inspection equipment also includes a control module, which is used to control the actions of the inspection clamping module 1, the vision module 2, and the loading and unloading module 3.

[0052] Homework process: The loading clamp 311 moves along the Y-axis direction to the initial loading position via the loading Y-axis moving module 313, so that the loading clamp 311 clamps the PCB board for material removal; the loading clamp 311 moves along the X-axis direction via the loading X-axis moving module 312 to the space between the fixed clamping component 11 and the movable clamping component 12, so that the PCB is in the initial detection position, and then moves downward via the loading Z-axis moving module 314 and moves towards the fixed clamping component 11 via the loading Y-axis moving module 313, so that the clamping teeth are inserted into the first gap 1121 and the clamping component is inserted into the second gap 3117. At this time, the PCB board is in contact with the fixed clamping component 112 and the first correction plate 113.

[0053] The distance adjustment component 13 drives the movable clamping component 12 to move towards the fixed clamping component 11, so that the pressure plate 1221 first contacts the PCB board and performs initial clamping. The movable clamping component 12 continues to move, so that the second straightening plate 123 adheres to the PCB board and flattens the PCB board, completing the warping correction of the PCB board. At this time, the PCB board is clamped by the fixed clamping component 11 and the movable clamping component 12.

[0054] The loading clamp 311 releases the PCB board, and the loading clamp 311 moves upward and detaches from the PCB board by the loading Z-axis moving module 314; then the loading clamp 311 is returned to the loading position by the loading X-axis moving module 312.

[0055] The positioning camera 23 first takes a picture of the upper right corner of the PCB board to confirm the board surface information. The front left inspection camera 21 and the front right inspection camera 22 perform zone inspection of the PCB board under the action of the first three-axis module 26 and the second three-axis module 27, respectively. The reverse vision component performs the same operation to achieve dual-sided dual-camera joint inspection.

[0056] During the camera's inspection of the PCB board, the unloading clamp 321 is moved in advance by the unloading X-axis moving module 322 to the top of the inspection clamping module 1, i.e., above the PCB board. After the inspection, the unloading Z-axis moving module 324 drives the unloading clamp 321 to move downward along the Z-axis to the PCB board clamping position and clamp the PCB board. The distance adjustment component 13 drives the movable clamping component 12 to move away from the fixed clamping component 11, releasing the PCB board. The unloading clamp 321, driven by the unloading Z-axis moving module 324 and the unloading Y-axis moving module 323, moves the PCB board to the initial inspection position. Finally, the unloading clamp 321, driven by the unloading X-axis moving module 322, retracts to the unloading position, and the unloading clamp 321 releases the PCB board to complete the unloading.
