Description

Technical Field

[0001] This utility model relates to the field of three-axis motion control and detection technology, and in particular to a detection device based on three-axis motion control. Background Technology

[0002] A three-axis motion mechanism includes three linear axes: X, Y, and Z. These axes can move individually or in conjunction, enabling cameras or other measuring devices to be precisely positioned at any location in three-dimensional space. Monitoring components based on the three-axis motion mechanism offers extremely high detection speed while reducing labor costs.

[0003] A search revealed Chinese patent application number 201721543474.6, which discloses a vision inspection system based on three-axis motion control. It includes: a placement cabinet, a first support, a second support, a pickup module, a first vision module, a conveyor line, a second vision module, and an information platform module. The first vision module acquires product images, and the pickup module uses a three-axis robotic arm and pickup mechanism to pick up products with defects and transport them to the conveyor line. The second vision module then accurately judges the defects to identify them. This invention can inspect parameters such as size, color, shape, and flatness of electronic chips and similar products, eliminating manual inspection and saving time and labor costs. Limit switches are installed on the robotic arm; when the movement reaches a limit switch or a stop limit switch, the platform system issues a stop signal, ensuring safety during the movement process.

[0004] Although the aforementioned patent can detect components and pick up defective components, its picking mechanism uses the suction force of a vacuum suction cup to pick up the components. In use, if the picking surface of the component is relatively rough, there will be problems such as picking failure on the production line and dropping during the picking process. For such rough surfaces, the single vacuum suction cup is not ideal.

[0005] Therefore, there is an urgent need for a detection device based on three-axis motion control to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the gripping effect of a single vacuum suction cup is not ideal when the gripping surface is relatively rough in the prior art, and to propose a detection device based on three-axis motion control.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A detection device based on three-axis motion control includes a housing and a carrier plate mounted on the top of the housing. Support plates are symmetrically mounted on the top of the carrier plate. A first slide rail is mounted on one of the support plates. A slider on the first slide rail is connected to one end of a second slide rail. A third slide rail is slidably mounted on the second slide rail. A mounting base is slidably connected to the third slide rail. A vision detection device is connected to one side of the top of the mounting base via a connecting plate. A mounting plate is located on one side of the mounting base below the connecting plate. A gripping mechanism is mounted on the third slide rail. The gripping mechanism includes a motor mounted on the bottom of the mounting plate. The output end of the motor is connected to a rotating plate. A first support plate and a second support plate are located on the outer side of the rotating plate. A first gripping component is mounted on the first support plate, and a second gripping component is mounted on the second support plate. A detection carrier plate is located between the two support plates.

[0009] As a preferred technical solution of this application, the first slide rail is perpendicularly connected to the second slide rail, and the second slide rail is perpendicularly connected to the third slide rail.

[0010] As a preferred technical solution of this application, the other end of the second slide rail is connected to a support plate mounted on the top of a support plate away from the first slide rail.

[0011] As a preferred technical solution of this application, the top of the carrier plate is provided with a conveyor that penetrates the support plate on one side of the detection carrier plate.

[0012] As a preferred technical solution of this application, the first gripping component includes a telescopic component and a vacuum suction cup connected to the telescopic component, and the second gripping component includes a telescopic component and a gripper connected to the telescopic component. The gripper includes a housing, a motor, an output shaft, a fastening device, and a clamping plate.

[0013] As a preferred technical solution of this application, the telescopic component includes a cylinder, one end of which is equipped with a first partition plate, and the first partition plate is connected to a second partition plate via a connecting rod.

[0015] As a preferred technical solution of this application, the conveyor is provided with multiple conveying routes.

[0016] Compared with the prior art, this utility model provides a detection device based on three-axis motion control, which has the following beneficial effects:

[0017] 1. The detection device based on three-axis motion control, through the setting of a first gripping component and a second gripping component, realizes the switching between the first gripping component and the second gripping component under the drive of the motor according to the gripping needs, which facilitates the gripping of items with poor surface flatness and solves the problem that the gripping effect of a single vacuum suction cup is not ideal when the gripping surface is relatively rough in the prior art.

[0018] 2. This detection device based on three-axis motion control, through the telescopic component, enables the gripping component that is not performing gripping work to be raised when switching between the first gripping component and the second gripping component, thereby reducing the impact on the gripping component that is performing gripping work. This solves the problem in the prior art where the two gripping components are located in the same plane, and the gripping component that is not performing gripping work is prone to accidentally touching the components or the table during gripping.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Reference Figures 1-4A detection device based on three-axis motion control includes a housing 1 and a carrier plate 2 mounted on the top of the housing 1. Support plates 3 are symmetrically mounted on the top of the carrier plate 2. A first slide rail 4 is mounted on one of the support plates 3. A slider on the first slide rail 4 is connected to one end of a second slide rail 5. A third slide rail 6 is slidably mounted on the second slide rail 5. The first slide rail 4 is perpendicularly connected to the second slide rail 5, and the second slide rail 5 and the third slide rail 6 are perpendicularly connected. The first slide rail 4, the second slide rail 5, and the third slide rail 6 drive a gripping mechanism mounted on the third slide rail 6 to move, thereby moving the gripper located between the two support plates 3. The items on the detection carrier plate 20 are inspected. The detection carrier plate 20 is used to carry the items to be inspected. The other end of the second slide rail 5 is connected to the support plate 21 installed on the top of the support plate 3 away from the first slide rail 4. The support plate 21 supports the second slide rail 5 and keeps it stable during operation. The top of the carrier plate 2 is provided with a conveyor 22 on one side of the detection carrier plate 20. The conveyor 22 passes through the symmetrical support plates 3 on the carrier plate 2 and is used to transport the unqualified components. The conveyor 22 has multiple conveying routes to facilitate the classification and transportation of components with different defects.

[0028] A mounting base 7 is slidably connected to the third slide rail 6. A visual inspection device 10 is connected to the top side of the mounting base 7 via a connecting plate 9. The visual inspection device 10 includes optical devices such as a high-resolution camera and a laser displacement sensor, which are used to capture and analyze the three-dimensional data of the object. A mounting plate 11 is provided on one side of the mounting base 7 below the connecting plate 9.

[0029] Reference Figure 3 and Figure 4 Furthermore, the gripping mechanism includes a motor 8 mounted on the bottom of the mounting plate 11. The output end of the motor 8 is connected to a rotating plate 12. A first support plate 18 and a second support plate 19 are provided on the outer side of the rotating plate 12. The included angle between the first support plate 18 and the second support plate 19 is 90°, which facilitates switching the positions of the first support plate 18 and the second support plate 19 by means of the motor 8. The switching is done by means of forward and reverse rotation, which prevents interference with the third slide rail 6 during rotation, making it more stable and convenient to use. A first gripping component is provided on the first support plate 18, and a second gripping component is provided on the second support plate 19. By using different gripping components, various types of items can be gripped, improving the convenience of use.

[0030] The first gripping component includes a telescopic component and a vacuum suction cup 16 connected to the telescopic component. The vacuum suction cup 16 generates suction by connecting to a vacuum generator to grip items on smooth surfaces. The second gripping component includes a telescopic component and a gripper 17 connected to the telescopic component. The gripper 17 includes a housing, a motor, an output shaft, a fastening device, and a clamping plate. After receiving a control signal, the motor starts to rotate and converts the rotational motion into linear motion of the gripper component through a transmission mechanism, thereby realizing the opening and closing action of the gripper. The gripper 17 is convenient for gripping items with rough surfaces that are not suitable for vacuum suction cups.

[0031] The telescopic assembly includes a cylinder 13. A first partition 14 is installed at one end of the cylinder 13. The first partition 14 is connected to a second partition 15 via a connecting rod. When the cylinder 13 is activated, a portion of the vacuum suction cup 16 or the gripper 17 can be retracted between the first partition 14 and the second partition 15, reducing the telescopic distance of the bottom end of the vacuum suction cup 16 or the gripper 17. Thus, when the vacuum suction cup 16 is used alone, the gripper 17 is retracted under the action of the cylinder 13, reducing the impact on the vacuum suction cup 16 and making the vacuum suction cup 16 more stable during use. Similarly, when the gripper 17 is used alone, the vacuum suction cup 16 is retracted.

[0032] Specifically, when this three-axis motion control-based detection device is in operation / use: the component to be detected is placed on the detection carrier plate 20 for detection. The vision detection device 10 and the gripping mechanism are moved by the first slide rail 4, the second slide rail 5 and the third slide rail 6. After the detection is completed, the gripping mechanism picks up the unqualified components and moves them to the conveyor 22, and the conveyor 22 transports the components.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
