[0037] To make the objectives, technical solutions, and advantages of 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 not intended to limit the scope of this application.

[0038] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0039] This application discloses a product full-size and thread inspection device. (Refer to...) Figure 1 The product's full-size and thread inspection equipment includes a displacement mechanism 1, a full-size inspection mechanism 2, a thread inspection mechanism, and a transfer mechanism 3. The displacement mechanism 1 is used to support and move the product; the full-size inspection mechanism 2 is used to inspect the full size of the product on the displacement mechanism 1; the thread inspection mechanism is used to support the product and inspect its threads; the transfer mechanism 3 is mounted above the displacement mechanism 1, the full-size inspection mechanism 2, and the thread inspection mechanism, and is used to transfer the product, allowing it to flow between the displacement mechanism 1 and the thread inspection mechanism.

[0040] With this design, the equipment is equipped with a displacement mechanism 1, a full-size inspection mechanism 2, a thread inspection mechanism, and a transfer mechanism 3. It can flexibly transfer the product to be tested and perform automated full-size and thread inspection of the product through the full-size inspection mechanism 2 and the thread inspection mechanism. This inspection process has a high degree of automation and high efficiency, greatly reducing the intensity of manual labor. Furthermore, the displacement mechanism 1 can adjust the inspection position of the product for the full-size inspection mechanism 2, making the inspection process extremely flexible and convenient.

[0041] In actual use of this equipment, the product to be inspected is transferred by the transfer mechanism 3 to the displacement mechanism 1. The displacement mechanism 1 then moves the product to a suitable inspection position. The full-size inspection mechanism 2 then performs full-size inspection on the product at the displacement mechanism 1. Subsequently, the transfer mechanism 3 transfers the product to the thread inspection mechanism, where the thread is inspected. This achieves automated full-size and thread inspection of the product.

[0042] Preferably, the testing equipment includes multiple substrates 9, and the equipment base is assembled by multiple substrates 9 to form equipment area division, and each mechanism is set on the corresponding substrate 9.

[0043] Furthermore, such as Figure 2As shown, in some embodiments, the displacement mechanism 1 includes a linear motion component 1-1 and a support platform 1-2. The support platform 1-2 is disposed at the movable end of the linear motion component 1-1 and is used to support the product. The linear motion component 1-1 includes, but is not limited to, using a linear module. Of course, in some embodiments, the linear motion component 1-1 can also be replaced by a multi-degree-of-freedom motion module.

[0044] Preferably, in some embodiments, when the displacement mechanism 1 includes a linear power member 1-1 and a support platform 1-2, the displacement mechanism 1 further includes a guide structure 1-3 for guiding the displacement direction of the support platform 1-2. The guide structure 1-3 includes, but is not limited to, using a linear guide rail.

[0045] In some embodiments, the guide structure 1-3 includes two sets of linear guides. The two sets of linear guides and the linear power component 1-1 are mounted in parallel on the base plate 9. The guide body of the linear guide is fixed on the base plate 9. The slider in the linear guide is connected to the movable end of the linear power component 1-1 or the support platform 1-2, and the sliding direction of the slider is consistent with the moving direction of the movable end of the linear power component 1-1.

[0046] Furthermore, such as Figure 2 As shown, in some embodiments, the full-size inspection mechanism 2 includes a multi-degree-of-freedom (DOF) power assembly 2-1 and a full-size camera 2-2. The multi-DOF power assembly 2-1 includes, but is not limited to, a multi-DOF robot (such as a six-axis robot). The full-size camera 2-2 is mounted on the movable end of the multi-DOF power assembly 2-1 and is used for the full-size inspection of the product. Its output is preferably a specific size value. The inspection principle of the full-size camera 2-2 is existing technology and will not be elaborated further here.

[0047] Furthermore, such as Figure 1 As shown, in some embodiments, the thread inspection mechanism includes: a go gauge inspection component 4 for inspecting the minimum permissible size of the thread pitch diameter of the product, and a no-go gauge inspection component 5 for inspecting the maximum permissible size of the thread pitch diameter of the product.

[0048] The go gauge inspection component 4 is positioned between the no-go gauge inspection component 5 and the displacement mechanism 1, while the displacement mechanism 1 is positioned between the full-size inspection mechanism 2 and the go gauge inspection component 4. Generally, the go gauge inspection component 4 is first used to determine the minimum permissible thread pitch diameter of the product, and then the no-go gauge inspection component 5 is used to determine the maximum permissible thread pitch diameter of the product.

[0049] Furthermore, such as Figure 3As shown, in some embodiments, the go gauge inspection component 4 includes a go gauge 4-1, a go gauge support 4-2, a product support 4-3, and a multi-degree-of-freedom robot. The go gauge 4-1 is used to inspect the threads of the product; the go gauge support 4-2 is used to support the go gauge 4-1; the product support 4-3 is used to support the product; and the multi-degree-of-freedom robot is used to pick up, place, and move the go gauge 4-1, and to use the go gauge 4-1 to inspect the threads of the product.

[0050] Preferably, the multi-degree-of-freedom (DOF) manipulator includes a multi-degree-of-freedom (DFS) drive component and a servo-electric gripper 4-5 mounted on the movable end of the DFS drive component. The DFS drive component includes, but is not limited to, a three-axis module 4-4 or a multi-degree-of-freedom robotic arm. When the DFS drive component is a three-axis module 4-4, the product support 4-3 is placed below the three-axis module 4-4, and the go gauge support 4-2 is placed below the three-axis module 4-4 and adjacent to the product support 4-3. The servo-electric gripper 4-5 is a dual-servo gripper integrating clamping and rotation. When the servo-electric gripper 4-5 does not have a rotation function, the DFS drive component should be equipped with a rotation module for driving the rotation of the servo-electric gripper 4-5. Preferably, the output of the thread detection is the torque value generated during the detection process.

[0051] Furthermore, such as Figure 3 As shown, the go gauge support 4-2 includes a base 4-2a, on which multiple bearing holes 4-2b are provided for supporting and positioning the go gauges 4-1. Generally, multiple go gauges 4-1 are provided, and each go gauge 4-1 has a different specification and model to facilitate the inspection of different thread specifications. For example, when the product has four thread specifications: M4, M6, M8, and M10, the go gauge inspection assembly 4 is equipped with at least multiple go gauges 4-1 for inspecting these four thread specifications.

[0052] Preferably, the no-go gauge inspection component 5 has a basically the same structure as the go gauge inspection component 4, except that the go gauge 4-1 is replaced with the no-go gauge.

[0053] Furthermore, the product support base 4-3 includes a base plate 4-3a and multiple support columns 4-3b, wherein the multiple support columns 4-3b are fixed at intervals to the outer periphery of the base plate 4-3a. In actual use, the user can place the product on the surface of the base plate 4-3a or on the multiple support columns 4-3b through the transfer mechanism 3, so that the product is suspended in the air, according to the user's needs.

[0054] Furthermore, such as Figure 4As shown, the transfer mechanism 3 includes a gripper 3-1, a three-axis gantry 3-2, and a mounting bracket 3-3. The gripper 3-1 is mounted on the three-axis gantry 3-2, and the mounting bracket 3-3 is used to support the three-axis gantry 3-2. The three-axis gantry 3-2 can drive the gripper 3-1 to adjust its position in space along the X-axis, Y-axis, and Z-axis directions. The gripper 3-1 is preferably a servo-electric gripper.

[0055] During operation, the three-axis gantry 3-2 moves the gripper 3-1 to a suitable position to pick up or place the workpiece, enabling the product to move within the full-size and thread inspection equipment. In some other embodiments, the three-axis gantry 3-2 can also be replaced by a multi-degree-of-freedom robotic arm, etc.

[0056] Furthermore, such as Figure 1 As shown, in some embodiments, the testing equipment is further configured with an incoming material station 6, an NG station 7 (i.e., a non-conforming product station), and an unloading station 8 (i.e., a conforming product station). A transfer mechanism 3 is located above the incoming material station 6, NG station 7, and unloading station 8. The transfer mechanism 3 can transfer products from the incoming material station 6 to the NG station 7 and the unloading station 8. Preferably, the incoming material station 6 is equipped with an inlet for receiving incoming products; the unloading station 8 is equipped with an outlet for discharging conforming products. Conveyor belts are preferably installed at the incoming material station 6 and the unloading station 8, and a receiving platform is preferably installed at the NG station 7.

[0057] Preferred, such as Figure 1 As shown, the displacement mechanism 1 and the go gauge detection component 4 are arranged diagonally, and the go gauge detection component 4 and the no-go gauge detection component 5 are arranged side by side; the NG station 7 and the unloading station 8 are arranged side by side and are located on the same side of the go gauge detection component 4 and the no-go gauge detection component 5. The NG station 7 is located in the diagonal empty area between the displacement mechanism 1 and the go gauge detection component 4, while the material receiving station 6 is located in the other diagonal empty area between the displacement mechanism 1 and the go gauge detection component 4.

[0058] By configuring the go gauge inspection component 4 and the no-go gauge inspection component 5, and by arranging each component, mechanism and workstation in a specific position, the transfer mechanism 3 can smoothly and with a short stroke transfer the product to various places, thereby achieving effective utilization of equipment space, which is conducive to the miniaturization of the equipment.

[0059] Furthermore, this equipment also includes a control module (not shown in the figure), which is electrically connected to the displacement mechanism 1, the full-size detection mechanism 2, the thread detection mechanism, and the transfer mechanism 3, and is used to control the operation of each mechanism. The control principle of the control module is existing technology and will not be elaborated here.

[0060] In actual use, the control module controls the transfer mechanism 3 to pick up and transfer the product to be tested from the incoming material station 6 to the displacement mechanism 1. The displacement mechanism 1 adjusts the product to a suitable displacement (or does not adjust it), and then the six-axis robot drives the full-size camera 2-2 to inspect the product's dimensions. The inspection data is sent to the control module in real time, which processes and analyzes the data to determine whether the product's full dimensions are qualified. If the product's full dimensions are qualified, the control module controls the transfer mechanism 3 to transfer the product to the thread inspection mechanism's go gauge inspection component 4 for thread inspection. If the product's full dimensions are unqualified, the product is transferred to the NG station 7.

[0061] During thread inspection, the three-axis module 4-4 drives the servo electric gripper 4-5 to clamp the go gauge 4-1 and perform rotation inspection on the thread at a specific position on the product. The servo electric gripper 4-5 provides real-time feedback on the torque of the go gauge 4-1 in the thread and sends the real-time inspection data to the control module for further judgment and control. The control module then determines whether the thread of the product is qualified based on the data.

[0062] If the thread inspection component 4 passes the test, the control module controls the transfer mechanism 3 to transfer the product to the no-go gauge inspection component 5 for inspection. If the thread inspection component 4 fails the test, the product is transferred to the NG station 7. Subsequently, if the thread inspection component 5 fails the test, the control transfer mechanism 3 transfers the product to the NG station 7 for centralized placement of non-conforming products. If the thread inspection component 5 passes the test, the control transfer mechanism 3 transfers the product to the unloading station 8.
