Description

Technical Field

[0001] This application belongs to the field of testing equipment technology, and in particular relates to a misaligned riveting detection device and a testing and sorting system. Background Technology

[0002] With continuous social progress and rapid technological development, the market demand for many products is increasing, and the requirements are also becoming more stringent. Therefore, it is essential to both ensure product quality and improve production efficiency to meet market demands. Currently, many products use rivets, and during the production process, the misinstallation or omission of rivets can easily occur, necessitating inspection of finished products. Traditional inspection methods generally fall into two categories: visual inspection using the naked eye and light transmission inspection of rivet holes. For visual inspection using the naked eye, the results rely on observing light leakage with the naked eye. Operators need to be in a state of observation for extended periods, which can easily lead to incorrect judgments. This is especially true when other pre-drilled mounting holes are present on the product, which can easily cause visual confusion, affecting inspection efficiency and stability.

[0003] For rivet hole light transmission inspection, it offers higher stability compared to manual visual inspection, but it is also more complex and costly. Light transmission inspection can only detect missing rivets, but it cannot detect incorrect rivet installation (e.g., installing rivets of different specifications).

[0004] Therefore, the existing rivet inspection methods still have many shortcomings and do not meet the inspection requirements of today's production lines. Summary of the Invention

[0005] The purpose of this application is to provide a mis-rivet detection device and a detection and sorting system to solve the technical problem that existing detection equipment cannot detect mis-rivets.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide a misaligned riveting detection device, comprising:

[0008] Base;

[0009] A mounting plate is disposed on the base. The mounting plate is used to mount the workpiece. The mounting plate is provided with light-transmitting holes that mate with the rivet positions on the workpiece.

[0010] A laser plate is disposed within the base and located below the mounting plate; the laser plate is provided with a laser rangefinder that mates with the position of the light-transmitting hole, the laser rangefinder being used to detect the distance between itself and the rivets on the workpiece and to upload the detection data to the host computer.

[0011] In this way, a laser rangefinder is used to detect the distance between itself and the rivets on the workpiece, and the detection data is uploaded to the host computer for data comparison, so as to quickly determine whether the workpiece has missing rivets or incorrect rivets, effectively improving the detection efficiency.

[0012] The overall structure of the misalignment detection device is improved. The base has an upper opening, and the mounting plate covers the upper opening of the base. A step is provided on the inner wall of the base, and the laser plate is placed on the step. This simplifies the mounting structure of the mounting plate and laser plate on the base, facilitating quick replacement of mounting plates and laser plates that fit workpieces of different specifications, and effectively improving the adaptability of the detection device.

[0013] In one embodiment, the base is further provided with positioning posts, and the edge of the mounting plate is provided with positioning holes that mate with the positioning posts. Thus, during the replacement of the mounting plate and the laser plate, the positioning holes on the mounting plate correspond one-to-one with the positioning posts on the base, allowing the light-transmitting holes on the mounting plate to automatically align with the laser rangefinder on the laser plate, effectively preventing installation errors and improving installation efficiency.

[0014] The structure of the mounting plate is improved by incorporating a pressure sensor electrically connected to a laser rangefinder on the laser plate, which controls the start and stop of the laser rangefinder. This allows the pressure sensor to detect whether a workpiece is mounted on the mounting plate, serving as a trigger switch for the laser rangefinder. The laser rangefinder is only activated when a workpiece is mounted, effectively preventing it from operating for extended periods and saving energy.

[0015] In one embodiment, the mounting plate further includes multiple limiting blocks for defining the workpiece mounting position and mounting slots for mounting the limiting blocks. The mounting slots of the mounting plate have adjustment holes, which are elongated holes extending towards the central region of the mounting plate. The limiting blocks are fixed to the adjustment holes by fasteners. This allows for quick fine-tuning by adjusting the proximity of each limiting block to the central region of the mounting plate, facilitating the mounting and fixing of workpieces of different sizes and specifications, thereby improving the adaptability of the workpiece mounting.

[0016] In one embodiment, the limiting block has a chamfer, which is configured as a guide surface on the limiting block. During workpiece installation, the workpiece can be automatically installed into position along the guide surface on the limiting block, effectively improving the installation efficiency of the workpiece.

[0017] Secondly, embodiments of this application also provide an inspection and sorting system, including a first loading tray, a second loading tray, and a third loading tray, a robot, and the aforementioned mis-riveting detection device: the first loading tray, the second loading tray, and the third loading tray are respectively used to place workpieces; the robot is configured to pick up workpieces from the first loading tray and place them on the mis-riveting detection device for inspection, and place qualified workpieces on the second loading tray, or unqualified workpieces on the third loading tray. Thus, by using a robot to replace manual labor for loading and sorting of inspected workpieces, work stability and efficiency are effectively improved.

[0018] The structure of the material carriers is improved so that the first, second, and third material carriers each include a loading box, and the loading box contains a grid for placing workpieces. The material carriers also have multiple dividing slots for placing the loading boxes, and these slots are arranged in an orderly manner along the length of the material carrier. This facilitates the operator in quickly counting the number of workpieces, thereby improving work efficiency.

[0019] In one embodiment, sensors are diagonally arranged on both sides of the loading bin, and sensing parts are located on the side walls of each of the partition slots on the material tray. These sensing parts are used to engage with the sensors on the loading bin. Thus, the diagonally arranged sensors on the loading bin allow the loading bin to operate regardless of orientation, enabling automatic alignment between the chips on the loading bin and the sensing parts on the material tray, thereby improving positional adaptability.

[0020] The robot's structure is improved by including a first robotic arm and a second robotic arm. The first robotic arm is configured to transfer workpieces from the first loading tray to the mounting plate of the misalignment detection device; the second robotic arm is configured to transfer the detected workpieces from the mounting plate to the second or third loading tray. Thus, by utilizing two robotic arms to perform feeding and sorting operations on the workpieces respectively, operational efficiency and accuracy are effectively improved.

[0021] The beneficial effects of the mis-riveting detection device and detection sorting system provided in this application are as follows: Compared with the prior art, the detection sorting system of this application uses robots to replace human hands for feeding and sorting of the detected workpieces, which effectively improves work stability and work efficiency.

[0022] The misfit detection device of this application includes a base, a mounting plate, and a laser plate. The laser plate is disposed within the base and located below the mounting plate. The laser plate is equipped with a laser rangefinder that mates with the rivet positions on the workpiece. The workpiece is mounted on the mounting plate such that the rivet positions on the workpiece correspond to the positions of the light-transmitting holes on the mounting plate. The laser rangefinder detects the distance between itself and the rivets on the workpiece, and the detection data is uploaded to a host computer for data comparison. This allows for rapid determination of whether there are missing or incorrectly installed rivets on the workpiece, effectively improving detection efficiency. Attached Figure Description

[0044] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0045] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] In practical applications, rivets need to be installed on workpieces to meet production requirements. During the production inspection process, it is necessary to check whether there are any missing or incorrect rivets on the workpieces.

[0049] Traditional rivet inspection equipment can only detect missing rivets. A light-transmitting inspection device, however, can address this by using a different approach. This device features a detection auxiliary plate with light-transmitting holes, each corresponding to a specific location on the workpiece where a rivet is to be installed. During inspection, the workpiece is placed on the detection auxiliary plate, and a light source illuminates the area to determine if the light-transmitting holes are blocked. If a rivet is installed at the designated location on the workpiece, it will block the corresponding light-transmitting hole on the detection auxiliary plate; conversely, if a rivet is missing from the designated location, it will not block the corresponding light-transmitting hole. This allows for rapid inspection and improves the efficiency of missing rivet detection.

[0050] However, due to varying production requirements, the specifications of rivets on workpieces differ. Some workpieces have uniform rivet specifications, while other workpieces require different rivet specifications for different locations. This leads to frequent instances during production where rivets of different specifications (mainly referring to rivets of different lengths) are mistakenly installed in their designated positions on the workpieces. Current inspection equipment cannot detect misinstalled rivets and relies solely on visual inspection, which is prone to errors and results in very low inspection efficiency.

[0051] Therefore, this application provides a novel misfit detection device and detection and sorting system, which can detect whether there are misfit rivets on the workpiece and automatically realize the sorting operation, effectively improving the detection efficiency and solving the problem that traditional detection equipment cannot detect misfits. It will now be described in detail.

[0052] Please refer to the following: Figure 1 and Figure 2The inspection and sorting system includes a first loading tray 11, a second loading tray 12, a third loading tray 13, a robot 2, and a mis-rivet detection device 100 provided in the embodiments of this application.

[0053] The first loading tray 11, the second loading tray 12, and the third loading tray 13 are used to place the workpiece 200. The first loading tray 11 is located on one side of the mis-riveting detection device 100, and the second loading tray 12 and the third loading tray 13 are located on the other side of the mis-riveting detection device 100, so that each loading tray is within the range of motion of the robot 2.

[0054] Robot 2 is configured to pick up workpiece 200 from the first loading tray 11 and place it on the mis-riveting detection device 100 for inspection. It then places the qualified workpiece 200 on the second loading tray 12 or the unqualified workpiece 200 on the third loading tray 13, thereby realizing the inspection and automatic sorting of workpiece 200, effectively replacing manual inspection and improving inspection efficiency.

[0055] "Workpieces that pass inspection" can be understood as workpieces 200 that have been confirmed by the device to have no mis-riveted parts; "workpieces that fail inspection" can be understood as workpieces 200 that have been confirmed by the device to have mis-riveted parts.

[0056] Please refer to the following: Figure 3 , Figure 4 and Figure 5 The mis-riveting detection device 100 on the detection and sorting system includes a base 3, a mounting plate 4, and a laser plate 5.

[0057] The base 3 has a box-like structure, which houses the laser plate 5. The mounting plate 4 is placed on the base 3 and located above the laser plate 5.

[0058] Mounting plate 4 is used to mount workpiece 200. Mounting plate 4 is provided with light-transmitting holes 41. The number of light-transmitting holes 41 on mounting plate 4 is the same as the number of rivet positions on workpiece 200, and their positions correspond one-to-one.

[0059] Please refer to the following: Figure 4 and Figure 5 The laser plate 5 is located below the mounting plate 4. The laser plate 5 is equipped with laser rangefinders 51. The number of laser rangefinders 51 on the laser plate 5 is the same as the number of light-transmitting holes 41 on the mounting plate 4, and their positions correspond one-to-one. For example... Figure 6As shown, the laser rangefinder 51 is used to detect the distance L between itself and the rivet 201 on the workpiece 200, and uploads the detection data to the host computer (not shown). In this embodiment, the laser plate 5 has multiple receiving slots 50 for mounting the laser rangefinder 51, and the opening of each receiving slot 50 is located on the surface of the laser plate 5. A smaller model of laser rangefinder 51 can be preferably used so that it can be housed within the receiving slot 50 and output detection light towards the opening of the receiving slot 50, effectively saving space.

[0060] Therefore, data comparison is performed using a host computer. Specifically, the host computer stores distance data that meets the requirements, and compares the stored distance data with the uploaded distance data to quickly determine whether there are missing or incorrectly installed rivets on the corresponding parts of the workpiece 200. Based on the detection results, robot 2 transfers the workpiece 200 to the second loading tray 12 or the third loading tray 13, thereby completing the detection and sorting operation.

[0061] It should be noted that the robot 2, laser rangefinder 51, and host computer mentioned above all utilize their inherent functions. For example, robot 2 can be a parallel robot or a robotic arm, capable of transferring objects to designated locations according to instructions. Laser rangefinder 51 has an automatic ranging function, such as a commonly used laser rangefinder. The host computer can preferably be a control host, such as a computer, which has internal storage and comparison computing capabilities. These devices can be linked and controlled, specifically using existing common linkage control methods to achieve the corresponding operations, such as using collected data for comparison and identification, allowing the parallel robot to perform corresponding operations based on the identified information. This application does not involve improvements to their functions or control methods.

[0062] Compared with the prior art, the mis-riveting detection device 100 and detection and sorting system provided in this application use a robot 2 to replace human hands for feeding and sorting the detected workpieces 200, which effectively improves work stability and work efficiency.

[0063] For detecting missing or incorrect rivets, the incorrect rivet detection device 100 of this application includes a base 3, a mounting plate 4, and a laser plate 5. The laser plate 5 is disposed within the base 3 and located below the mounting plate 4. The laser plate 5 is equipped with a laser rangefinder 51 that mates with the rivet positions on the workpiece 200. The workpiece 200 is mounted on the mounting plate 4 such that the rivet positions on the workpiece 200 correspond to the positions of the light-transmitting holes 41 on the mounting plate 4. The laser rangefinder 51 detects the distance between itself and the rivets on the workpiece 200, and uploads the detection data to a host computer for data comparison, thereby quickly determining whether there are missing or incorrectly installed rivets on the workpiece 200, effectively improving detection efficiency.

[0064] In practical applications, the rivet locations on workpieces of different specifications 200 vary, requiring adaptive adjustments to the mounting plate 4 and laser plate 5 on the mis-rivet detection device 100. In one embodiment of this application, please refer to... Figure 7 The base 3 has an upper opening 31, and the mounting plate 4 covers the upper opening 31 of the base 3. The inner wall of the base 3 is provided with a step 32, and the laser plate 5 is placed on the step 32 so that the laser plate 5 is housed inside the base 3.

[0065] Therefore, the mounting structure of the mounting plate 4 and laser plate 5 on the base 3 is very simple, which facilitates the quick replacement of mounting plates 4 and laser plates 5 to fit different specifications of workpieces. In practical applications, different mounting plates 4 and laser plates 5 can be set according to the different rivet positions on different specifications of workpieces 200. Specifically, the number and position of the light-transmitting holes 41 on the mounting plate 4 and the laser rangefinders 51 on the laser plate 5 are set according to the rivet positions on different specifications of workpieces 200, so that the light-transmitting holes 41 on the mounting plate 4 and the laser rangefinders 51 on the laser plate 5 can fit with the workpiece 200. Before using the detection device, a suitable mounting plate 4 and laser plate 5 can be selected and installed on the base 3 before detection, effectively improving the adaptability of the detection device.

[0066] For the aforementioned paired mounting plate 4 and laser plate 5, the light-transmitting hole 41 on the mounting plate 4 and the laser rangefinder 51 on the laser plate 5 need to be positioned one-to-one after being installed on the base 3 so that each laser rangefinder 51 can be accurately aligned with the rivet part on the workpiece 200; otherwise, detection will be impossible.

[0067] To improve the alignment accuracy between the mounting plate 4 and the laser plate 5, in another embodiment of this application, please refer to... Figure 8 The base 3 is provided with a plurality of positioning posts 33, which are arranged around the upper opening 31 of the base 3. Correspondingly, the mounting plate 4 has the same number of positioning holes 42 as the positioning posts 33 on its edge, and the positions of these positioning holes 42 correspond one-to-one with the positions of the positioning posts 33.

[0068] Thus, during the replacement of laser plate 5 and mounting plate 4, laser plate 5 is first embedded into the step 32 of base 3 for automatic positioning, and mounting plate 4 covers the upper opening 31 of base 3, so that the positioning holes 42 on mounting plate 4 correspond one-to-one with the positioning posts 33 on base 3. This allows the light-transmitting holes 41 on mounting plate 4 to automatically align with the laser rangefinder 51 on laser plate 5, effectively preventing installation errors and improving installation efficiency and convenience.

[0069] Regarding the structure on mounting plate 4, please refer to one embodiment of this application. Figure 9The mounting plate 4 is equipped with a pressure sensor 43, which is used to contact the workpiece 200 mounted on the mounting plate 4 to detect whether the workpiece 200 is mounted on the mounting plate 4.

[0070] The pressure sensor 43 is electrically connected to the laser rangefinder 51 on the laser plate 5 and controls the start and stop of the laser rangefinder 51. The electrical connection between the pressure sensor 43 and the laser rangefinder 51 can be understood as an indirect connection, which is achieved by a controller or host computer to control the start and stop of the laser rangefinder 51.

[0071] When the workpiece 200 is placed on the mounting plate 4, the pressure sensor 43 is triggered, causing the pressure sensor 43 to send a detection signal. The laser rangefinder 51 on the laser plate 5 then turns on to perform distance measurement based on the detection signal.

[0072] In this way, the pressure sensor 43 is used to detect whether the workpiece 200 is installed on the mounting plate 4, and serves as the start trigger switch for the laser rangefinder 51. The laser rangefinder 51 is only started when the workpiece 200 is installed, which effectively avoids the laser rangefinder 51 from being turned on for a long time and saves energy.

[0073] For the structure on mounting plate 4, please refer to another embodiment of this application. Figure 9 and Figure 10 The mounting plate 4 is also provided with a limiting block 44 and a mounting groove 45 for mounting the limiting block 44. Multiple limiting blocks 44 are provided and are used to limit the mounting position of the workpiece 200 on the mounting plate 4.

[0074] In this embodiment, as Figure 9 As shown, the central region M on the mounting plate 4 is used to mount the workpiece 200. The aforementioned limiting block 44 is provided along the edge of the mounting plate 4 and moves toward the central region M of the mounting plate 4, thereby limiting the mounting position of the workpiece 200.

[0075] The mounting plate 4 has an adjustment hole 46 in its mounting groove 45, which is preferably an elongated hole extending toward the central region M of the mounting plate 4. The limiting block 44 is fixed to the adjustment hole 46 by fasteners such as screws.

[0076] In this way, by using the adjustment hole 46 to adjust the proximity of each limit block 44 to the middle area M of the mounting plate 4, a rapid fine adjustment can be achieved, which is beneficial for the installation and fixing of workpieces 200 of different sizes and specifications, thereby improving the installation adaptability of workpieces 200.

[0077] Preferably, such as Figure 9 and Figure 10As shown, each limiting block 44 is provided with a chamfer 441. Specifically, it is preferred that the chamfer 441 is provided on the side of the limiting block 44 near the middle region M of the mounting plate 4. The chamfer 441 is constructed as a guide surface on the limiting block 44.

[0078] Thus, when robot 2 places workpiece 200 on mounting plate 4, workpiece 200 can slide into the middle area M of mounting plate 4 along the guide surface on limit block 44, achieving automatic installation and effectively improving the installation efficiency of workpiece 200.

[0079] For the structure of the loading tray, please refer to one embodiment of this application. Figure 11 and Figure 12 The first loading tray 11, the second loading tray 12 and the third loading tray 13 have the same structure. Each loading tray includes a loading box 14. The loading box 14 is provided with a grid 141 for placing workpieces 200 respectively. Each grid 141 is configured to accommodate a vertically placed workpiece 200.

[0080] Workpieces 200 can be placed in each grid 141, which facilitates quick counting of the number of workpieces 200. For example, ... Figure 11 As shown, each loading box 14 preferably has 10 grid positions, so that a loading box 14 filled with workpieces 200 can quickly count 10 workpieces 200.

[0081] like Figure 11 As shown, the loading tray is also provided with multiple partition slots 15 for placing the loading boxes 14 respectively. The multiple partition slots 15 are arranged in an orderly manner on the loading tray along the length direction of the loading tray.

[0082] The dividing groove 15 is preferably a rectangular groove that matches the shape of the loading box 14, so that the loading box 14 can be automatically positioned after being placed in the dividing groove 15 of each loading tray.

[0083] Therefore, the structure on the first loading tray 11, the second loading tray 12 and the third loading tray 13 is conducive to the operator quickly counting the number of workpieces 200, thereby improving the work efficiency.

[0084] Preferably, please refer to Figure 11 The material tray is provided with multiple partition plates 16, and the partition groove 15 is formed between adjacent partition plates 16. Among them, there is a baffle 17 on one side of the material tray connecting the adjacent partition plates 16, and there is a slot 151 on the other side of the material tray between the adjacent partition plates 16, so that the loading box 14 can slide into the partition groove 15 from one side slot 151; or, when unloading materials, the loading box 14 can be removed from the slot 151 of the partition groove 15.

[0085] Therefore, in practical applications, as an example, when robot 2 is performing a part-removal operation on the last loading box 14 with workpiece 200 on the loading tray, it can quickly replace the empty loading box 14 using the slot 151 of the partition 15, so that robot 2 can work continuously.

[0086] Further improvements to the structure of the loading tray are described in one embodiment of this application; please refer to that embodiment as well. Figure 11 and Figure 12 The material box 14 is equipped with a sensor 142, which can preferably be a data chip with storage and memory functions.

[0087] The material tray is provided with a sensing part 18 located on the side wall of each partition groove 15. The sensing part 18 is used to cooperate with the sensing element 142 on the loading box 14 to identify the sensing element 142 and upload it to the host computer for further application.

[0088] Preferably, such as Figure 12 As shown, the sensors 142 on the loading box 14 are arranged diagonally on both sides of the loading box 14 and are set in conjunction with the rectangular dividing slots 15 on the loading tray, so that the loading box 14 can be placed in the dividing slots 15 of the loading tray without being affected by the direction, so that the chip and the sensing part 18 can be automatically aligned, thereby improving the positional adaptability of the sensors 142 on the loading box 14 and the sensing part 18 on the loading tray.

[0089] Regarding the specific structure of robot 2, in one embodiment of this application, please refer to... Figure 1 and Figure 2 The robot 2 includes at least a first robotic arm (not shown) and a second robotic arm (not shown). The first robotic arm can preferably be disposed between the mis-riveting detection device 100 and the first material tray 11. The first robotic arm is configured to transfer the workpiece 200 on the first material tray 11 to the mounting plate 4 of the mis-riveting detection device 100.

[0090] The second robotic arm can preferably be positioned between the misalignment detection device 100, the second loading tray 12, and the third loading tray 13. The second robotic arm is configured to transfer the detected workpiece 200 from the mounting plate 4 to the second loading tray 12 or the third loading tray 13.

[0091] In this way, two robotic arms are used to feed and sort workpieces 200 respectively, which effectively improves the efficiency and accuracy of operation.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
