Description

Technical Field

[0001] This utility model belongs to the field of circuit board defect detection technology, specifically relating to a fully automatic flexible circuit board detection device. Background Technology

[0002] Since its development in the 1950s, flexible circuit boards (PCBs) have been widely used in various fields such as consumer electronics, new energy vehicles, and medical devices due to their advantages of flexibility, high integration, and lightweight design. However, the manufacturing process of flexible circuit boards is relatively complex and may result in various defects, thus necessitating defect detection.

[0003] Currently, in existing flexible circuit board defect detection systems, visual inspection devices are used to inspect flexible circuit boards. However, the position of the visual inspection component and the circuit board to be inspected in existing visual inspection devices is relatively fixed, resulting in a single inspection angle. There are many circuit boards that are judged as good but are actually defective. Therefore, it is usually necessary to manually visually re-inspect the entire flexible circuit board that has been judged as defective. The accuracy of the inspection cannot be improved, and the pressure of manual re-inspection is increased. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a fully automatic flexible circuit board testing equipment.

[0005] The technical solution adopted in this utility model is as follows: A fully automatic flexible printed circuit board (FPCB) inspection device includes a worktable, which comprises a frame, a gantry, and a product carrier. The gantry is fixedly mounted on the frame, and the product carrier is mounted on the frame. A moving component includes a connecting frame and a first linear module, which is mounted on the gantry and the connecting frame is fixedly mounted on a slide of the first linear module. An adjusting component includes a first rotary drive module and a second rotary drive module. The first rotary drive module includes a first drive unit fixedly mounted on the connecting frame and a first mounting bracket fixedly connected to the output end of the first drive unit. The second rotary drive module includes a second drive unit fixedly mounted on the first mounting bracket and a second mounting bracket fixedly connected to the output end of the second drive unit. A vision inspection component is fixedly mounted on the second mounting bracket.

[0006] For example, the moving component also includes a second linear module, which is mounted on the frame, and the product carrier is fixedly mounted on the slide of the second linear module.

[0007] For example, the product carrier includes a support frame and two symmetrically arranged product clamps. Each product clamp is provided with a third rotary drive module between itself and the support frame. The product clamps are fixedly connected to the output end of the third rotary drive module.

[0008] For example, the support frame is fixedly mounted on the slide of the second linear module.

[0009] For example, the product fixture includes a first action block, a second action block, and a driving member. The first action block and the second action block are connected by a pair of parallel connecting rods, and the two ends of the driving member are rotatably connected to the first action block and the second action block, respectively.

[0010] For example, the driving component is a cylinder, and the driving component and the connecting rod have an angle at any time.

[0011] For example, the visual inspection component includes a smart camera and a ring light source, both of which are mounted on a second mounting bracket, with the ring light source positioned on one side of the smart camera lens.

[0012] For example, the extension of the smart camera lens passes through the center of the ring light source.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional circuit board visual inspection devices, this device adds an adjustment component. By driving the first and second rotary drive modules in the adjustment component, the spatial position of the second mounting bracket can be adjusted. In turn, during the inspection process, the adjustment visual inspection component fixed on the second mounting bracket continuously adjusts its angle. This allows the visual inspection component to inspect the same point at different angles, increasing the flexibility of the visual inspection component. By combining multiple angles, the device can determine whether the product under test is good or defective, thereby increasing the accuracy of the inspection results and reducing the pressure of subsequent manual review.

Detailed Implementation

[0017] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application, and that the application can be implemented without one or more of these details. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0018] To fully understand the embodiments of this application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other embodiments.

[0019] Currently, in existing flexible circuit board defect detection systems, visual inspection devices are used to inspect flexible circuit boards. However, the positions of the visual inspection components and the circuit board to be inspected (hereinafter referred to as the product to be inspected) in existing visual inspection devices are relatively fixed, resulting in a single inspection angle. There are many circuit boards that are judged as good but are actually defective. Therefore, it is usually necessary to manually visually re-inspect the entire flexible circuit board that has been judged as defective. The accuracy of the inspection cannot be improved, and the pressure of manual re-inspection is increased.

[0020] See also Figures 1 to 3This application provides a fully automatic flexible circuit board testing device, including a workbench 100, which includes a frame 110, a gantry 120, and a product carrier 200. The gantry 120 is fixedly mounted on the frame 110, and the product carrier 200 is mounted on the frame 110. A moving component 300 includes a connecting frame 310 and a first linear module 320, which is mounted on the gantry 120 and the connecting frame 310 is fixedly mounted on the slide of the first linear module 320. An adjusting component 400 is also included. The adjustment assembly 400 includes a first rotary drive module 410 and a second rotary drive module 420. The first rotary drive module 410 includes a first drive part 411 fixedly mounted on the connecting frame 310 and a first mounting bracket 412 fixedly connected to the output end of the first drive part 411. The second rotary drive module 420 includes a second drive part 421 fixedly mounted on the first mounting bracket 412 and a second mounting bracket 422 fixedly connected to the output end of the second fixed part. A vision inspection assembly 500 is fixedly mounted on the second mounting bracket 422.

[0021] Compared with traditional circuit board visual inspection devices, this device adds an adjustment component 400. By driving the first rotary drive module 410 and the second rotary drive module 420 in the adjustment component 400, the spatial position of the second mounting bracket 422 can be adjusted. In turn, during the inspection process, the adjustment visual inspection component 500 fixed on the second mounting bracket 422 is continuously adjusted in angle. This allows the visual inspection component 500 to perform angle inspection on the same point, increasing the flexibility of the visual inspection component 500. By combining multiple angles, the device can determine whether the product under test is good or defective, thereby increasing the accuracy of the inspection effect and reducing the pressure of subsequent manual review.

[0022] The first linear module 320 can be a combination of motor, differential, and lead screw module. This structure is commonly used, and technicians can adjust the fixed installation positions of the motor, differential, and lead screw module according to the site conditions.

[0023] The first rotary drive module 410 can be a combination of a first motor, a first reducer and a first rotating platform. The first motor is connected to the first rotating platform through the first reducer. The fixed end of the first rotating platform is fixedly set in the connecting frame 310, and the output rotating end is fixedly connected to the first mounting bracket 412. The angle of the first mounting bracket 412 can be adjusted by driving the first motor.

[0024] The second rotary drive module 420 can be a combination of a second motor, a second reducer, and a second rotating platform. The second motor is connected to the second rotating platform through the second reducer. The fixed end of the second rotating platform is fixedly mounted on the first mounting bracket 412, and the output rotating end is fixedly connected to the second mounting bracket 422. The angle of the second mounting bracket 422 can be adjusted by driving the second motor.

[0025] See also Figure 1 The moving component 300 also includes a second linear module 330, which is mounted on the frame 110, and the product carrier 200 is fixedly mounted on the slide of the second linear module 330.

[0026] The second linear module 330 can be used to move the product carrier 200 along the second direction, thereby adjusting the position of the product under test fixed on the product carrier 200. Together with the adjustment component 400 and the first linear module 320, the product under test can be inspected from all angles.

[0027] The second linear module 330 is the same as the first linear module 320 and can also be a combination of a motor, differential, and lead screw module. This structure is commonly used, and technicians can adjust the fixed installation positions of the motor, differential, and lead screw module according to the site conditions.

[0028] See also Figure 1 and Figure 3 The product carrier 200 includes a support frame 210 and two symmetrically arranged product clamps 220. Each product clamp 220 is provided with a third rotary drive module 230 between it and the support frame 210. The product clamp 220 is fixedly connected to the output end of the third rotary drive module 230.

[0029] When fixing the product under test, the product clamps 220 set on both sides of the support frame 210 clamp the product under test on both sides, thereby fixing the product under test. After one side of the product under test is inspected, the third rotating module can be driven to rotate the product clamps 220 to flip the product under test, so that the vision inspection component 500 can inspect the other side of the product under test.

[0030] The third rotary drive module 230 can be a combination of a third motor, a third reducer and a third rotating platform. The third motor is connected to the third rotating platform through the third reducer. The fixed end of the rotating platform is fixedly set on the bearing frame 210, and the output rotating end is fixedly connected to the product fixture 220, thereby driving the third motor to flip the product to be tested.

[0031] The third rotary drive component can also be a third rotary cylinder. The fixed end of the third rotary cylinder is fixedly installed on the bearing frame 210, and the output rotary end is fixedly connected to the product fixture 220.

[0032] See also Figure 1 The supporting frame 210 is fixedly mounted on the slide of the second linear module 330.

[0033] The support frame 210 is fixedly mounted on the slide of the second linear module 330. The support frame 210, which is slidably connected to the frame 110, can be moved along the second direction by driving the second linear module 330. With the help of the adjustment component 400 and the first linear module 320, the product under test can be inspected in all directions.

[0034] See also Figure 3 The product fixture 220 includes a first action block 221, a second action block 222 and a drive member 223. The first action block 221 and the second action block 222 are connected by a pair of parallel connecting rods 224, and the two ends of the drive member 223 are respectively rotatably connected to the first action block 221 and the second action block 222.

[0035] By using two parallel connecting rods 224 to connect the first action block 221 and the second action block 222, the contact surfaces of the first action block 221 and the second action block 222 in contact with the product under test can always remain parallel. In the unclamped state, the first action block 221 and the second action block 222 are staggered, and the space provided can facilitate the prevention or removal of the product under test.

[0036] See also Figure 3 The driving component 223 is a cylinder, and the driving component 223 and the connecting rod 224 have an angle at any time.

[0037] During the installation of the selected drive cylinder, the cylinder and the connecting rod 224 need to maintain a certain angle at all times to prevent the cylinder from self-locking when driving the first action block 221 and the second action block 222 to move relative to each other. The above situation can be avoided by setting the included angle, so that the first action block 221 and the second action block 222 can achieve the clamping effect.

[0038] See also Figure 2 The visual inspection component 500 includes a smart camera 510 and a ring light source 520. Both the smart camera 510 and the ring light source 520 are mounted on the second mounting bracket 422, and the ring light source 520 is located on one side of the lens of the smart camera 510.

[0039] The ring light source 520 can illuminate the product to be tested from various angles. By placing the ring light source 520 on one side of the lens of the smart camera 510, the light source can be better utilized, preventing the smart camera 510 from blocking the light source itself and minimizing the impact of the light on the shooting effect of the smart camera 510.

[0040] See also Figure 2 The extension line of the lens of the smart camera 510 passes through the center of the ring light source 520.

[0041] The device's design, which directs the lens of the smart camera 510 towards the center of the ring light source 520, prevents the ring light source 520 from obstructing the lens of the smart camera 510 during use. The distance between the ring light source 520 and the smart camera 510 can be set according to the site conditions, ensuring that the smart camera 510 can capture the entire product under test.

[0042] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
