[0002] In the field of modern precision manufacturing, the dimensional accuracy, appearance quality and assembly performance of parts directly affect the performance and reliability of the final product. Therefore, efficient and accurate automated inspection of parts has become a key link in industrial production.

[0003] The existing methods for inspecting parts still have problems: part inspection, dispensing and curing rely heavily on manual operation, which is not only inefficient, but also easily affected by human factors, resulting in poor inspection consistency and high false detection rate, and it is also difficult to meet the needs of mass production and high precision.

[0004] Therefore, there is an urgent need for a testing station for parts to solve the above problems. Utility Model Content

[0048] In one embodiment of this utility model, such as Figure 1-5 As shown, a part inspection station is provided, including: a worktable 1, a rotating mechanism 2, an inspection unit group 3, and a positioning seat 4. The worktable 1; the rotating mechanism 2, rotatably mounted on the top surface of the worktable 1; the inspection unit group 3, distributed circumferentially along the rotating mechanism 2 on the worktable 1, includes a dispensing device 7, a vision inspection unit 8, a curing unit 11, a dimensional inspection unit 14, and a feeding unit 16; the positioning seat 4, mounted on the edge of the rotating mechanism 2, is used to carry the part to be inspected; the rotating mechanism 2 drives the positioning seat 4 to rotate through the inspection unit group 3 to execute an automated part inspection process; when the positioning seat 4 carries the part and rotates to the dispensing device 7, the dispensing nozzle of the dispensing device 7 is aligned with the dispensing position on the part and applies adhesive to the part surface.

[0049] The parts inspection station provided by this utility model, through the rotating mechanism 2 driving the positioning seat 4 to rotate, enables automated flow of parts between various inspection units, effectively improving inspection efficiency. The dispensing device 7 dispenses adhesive, avoiding manual dispensing. The vision inspection unit 8 utilizes machine vision technology to effectively identify surface defects in parts, unaffected by fatigue or other factors, ensuring the reliability of inspection results. The curing unit 11 rapidly cures the adhesive, ensuring stable product quality. The dimensional inspection unit 14 accurately measures part dimensions, achieving high-precision inspection. The unloading unit 16 automatically unloads materials, reducing manual intervention. The entire inspection process is seamless, effectively reducing labor costs, lowering the defect rate, and increasing the efficient speed of product production for enterprises.

[0050] Preferably, the rotating mechanism 2 can be a turntable, and the turntable has a simple structure, precise positioning, and can stably drive the parts to rotate.

[0051] Preferably, a positioning plate 19 can be rotatably mounted on the top surface of the turntable. The positioning plate 19 is stationary relative to the worktable 1. A clamping block 21, which uses a cylinder to clamp or release parts on the positioning seat 4, can be installed on the positioning plate 19. The stationary position of the positioning plate 19 relative to the worktable 1 facilitates stable clamping of parts by the clamping block 21, improves clamping accuracy and reliability, and helps to improve detection stability and automation.

[0052] In this embodiment, a three-axis robot 17 can be installed on the workbench 1 to control the movement path of the dispensing device 7, thereby achieving high precision and flexible control of the dispensing process and improving dispensing quality and work efficiency.

[0053] Preferably, the visual inspection unit 8 includes a camera 9 and a light source 10, both mounted on the worktable 1, and located circumferentially outside the rotating mechanism 2. The camera 9 is positioned directly above the rotating mechanism 2, and the light source 10 is arranged around the lens of the camera 9 and illuminates downwards. When the positioning seat 4 rotates the part to the visual inspection unit 8, the surface of the part to be inspected is perpendicular to the optical axis of the camera 9, and the camera 9 is used to acquire an image of the top of the part. The camera 9 and the light source 10 of the visual inspection unit 8 work together to ensure that the surface of the part to be inspected is perpendicular to the optical axis, enabling accurate acquisition of top images, improving inspection accuracy and stability, and facilitating efficient and reliable identification of appearance defects.

[0054] Preferably, the curing unit 11 includes a curing lamp 12 and a protective cover 13, both mounted on the worktable 1, and is located circumferentially outside the rotating mechanism 2. The protective cover 13 covers the outer periphery of the curing lamp 12. When the positioning seat 4 rotates to the curing unit 11 carrying the part, the light emitted by the curing lamp 12 is focused onto the surface of the part to achieve curing of the dispensing area. The curing unit 11 protects the curing lamp 12 through the protective cover 13, ensuring that the focused light efficiently irradiates the surface of the part, achieving rapid and uniform curing of the dispensing area, improving product curing quality and production efficiency, while reducing ambient light interference and enhancing process stability.

[0055] Preferably, the top surface of the positioning base 4 is provided with a protrusion 5 for accommodating parts and an opening 6 for measuring the concentricity of the parts. The protrusion 5 and the opening 6 ensure accurate positioning and stable placement of the parts, while the opening 6 facilitates the measurement of the concentricity of the parts, effectively ensuring product quality and consistency during testing.

[0056] Preferably, the dimension detection unit 14 includes a sliding measuring block 20, which can be driven to slide by a mounting cylinder. The sliding measuring block 20 is slidably mounted on the worktable 1, and the sliding direction of the sliding measuring block 20 is perpendicular to the circumferential path of the positioning seat 4. The front of the sliding measuring block 20 has a mating surface that matches the profile of the part to be measured. When the part arrives at the dimension detection unit 14 along with the positioning seat 4, the sliding measuring block 20 slides along the part, so that the mating surface fits against the profile of the part. The dimension detection unit 14 drives the sliding measuring block 20 to fit against the profile of the part by a cylinder, realizing fast and stable contact contour detection, improving detection accuracy and automation, and ensuring part dimensional consistency and detection efficiency.

[0057] Specifically, the dimension inspection unit 14 also includes a lifting measuring column 15, which can be vertically mounted on the worktable 1 by installing a cylinder. When the positioning seat 4 rotates with the rotating mechanism 2 past the dimension inspection unit 14, the lifting measuring column 15 passes through the opening 6 into the inner hole of the part. Measuring by inserting the lifting measuring column 15 into the inner hole of the part is simple in structure and precise in positioning, which can effectively improve the accuracy and efficiency of the concentricity of the inner hole being inspected, and further ensure the consistency of product quality.

[0058] Preferably, the unloading unit 16 includes a robot arm 17 and an unloading tray 18 both mounted on the worktable 1. The output end of the robot arm 17 moves back and forth between the unloading tray 18 and the parts on the positioning seat 4. Through the cooperation of the robot arm 17 and the unloading tray 18, the unloading unit 16 realizes automatic sorting and collection of parts, improves unloading efficiency and automation level, reduces manual intervention, and improves the overall production continuity and intelligence level.

[0059] In this invention, the robotic arm 17 can be composed of a cylinder and / or a slide, which drives the robotic arm 17 to move back and forth between the unloading tray 18 and the positioning seat 4.

[0060] The inspection station for this part also includes a transfer assembly 22, which is set on the workbench 1 and is used to transport the part.

[0061] Specifically, the transfer assembly 22 includes a connecting plate 23, a gripper 24, and a mounting base 25. The connecting plate 23 is movable and mounted on the worktable 1, allowing it to be moved via a mounting slide or cylinder. The gripper 24, located at the lower end of the connecting plate 23, has an openable and closable clamping portion. In practical applications, a cylinder can be used to drive the gripper 24 to open and close. The mounting base 25, located on the worktable 1 and on the outer circumferential side of the rotating mechanism 2, is used to support the parts. The gripper 24 moves with the connecting plate 23 and transfers the workpiece between the mounting base 25 and the positioning seat 4.

[0062] In this embodiment, the transfer component 22 drives the gripper 24 to move through the connecting plate 23, thereby realizing the automatic transfer of parts between the mounting base 25 and the positioning base 4, improving the workpiece flow efficiency and automation level, reducing manual operation, and enhancing the continuity and stability of the overall inspection process.

[0063] The inspection station for this part also includes a limiting seat 26 and a straightening fixture 27. The limiting seat 26 is mounted on the workbench 1, and its top has a limiting groove for adapting to the shape of the part. The straightening fixture 27 is swayably mounted on the side of the limiting seat 26. The output end of the straightening fixture 27 clamps the part in the limiting groove and straightens it to the corresponding position. The limiting seat 26 positions the part by adapting to the groove, and the straightening fixture 27 swings to fix the part in the groove and straightens the part's position, ensuring that the part is clamped in the next process.

[0064] In this embodiment, the alignment fixture 27 is composed of a suction cup 28, a rotary cylinder 29 and a drive plate 30. The drive plate 30 is mounted on the worktable 1 via a cylinder or a slide, the rotary cylinder 29 is mounted on the drive plate 30, and the suction cup 28 is mounted on the output end of the rotary cylinder 29.

[0065] The inspection station for parts provided by this utility model operates as follows: The part is placed in the limiting groove at the top of the limiting seat 26. The drive plate 30 moves towards the limiting seat 26 via a cylinder, causing the rotary cylinder 29 and the suction cup 28 at its end to approach the side of the part. The suction cup 28 picks up and removes the part, and the rotary cylinder 29 drives the suction cup 28 to rotate, aligning the part to a preset angle.

[0066] The connecting plate 23 is driven to move laterally by a slide cylinder, which moves the gripper 24 (driven to open and close by a cylinder) at one end of the connecting plate 23 to above the suction cup 28. The gripping part of the gripper 24 opens and clamps the workpiece, and then picks the part from the suction cup 28 to above the mounting base 25.

[0067] The connecting plate 23 is driven to move laterally by a slide cylinder, which moves the gripper 24 at the other end to above the mounting base 25. The gripping part of the gripper 24 opens to clamp the workpiece, and then picks the part from the mounting base 25 to above the positioning base 4.

[0068] At this point, the protrusion 5 on the top surface of the positioning seat 4 is embedded into the bottom slot of the part to achieve initial positioning. Then, the clamp 24 releases the part, and the connecting plate 23 returns to its original position to complete the loading.

[0069] Subsequently, the rotating mechanism 2 drives the positioning seat 4 to pass through each detection unit in the circumferential direction.

[0070] When the part reaches the dispensing device 7, the three-axis robot 17 drives the dispensing device 7 to precisely dispense adhesive onto the part along a preset path. Subsequently, the part enters the vision inspection unit 8. At this point, the camera 9 is positioned directly above the top of the part, and the light sources 10 are arranged around it and provide uniform illumination, ensuring that the surface to be inspected is perpendicular to the optical axis, thereby achieving high-precision image acquisition and accurately identifying appearance defects. Next, it enters the curing unit 11, where the light emitted by the curing lamp 12 is focused onto the surface of the part, causing the adhesive to cure quickly. The protective cover 13 effectively prevents external light interference and improves curing stability. Following this, the dimension inspection unit 14, through the sliding measuring block 20, fits against the surface of the part, and the lifting measuring column 15 penetrates the inner hole of the part to complete the inspection of the part's internal and external dimensions.

[0071] After the inspection is completed, the robotic arm 17 of the unloading unit 16 picks up the parts from the positioning seat 4 and places them in the unloading tray 18, realizing automatic sorting and collection.

[0072] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
