Description

Technical Field

[0001] This invention relates to the field of automotive parts testing technology, specifically to an automated batch conveying and testing device for automotive parts. Background Technology

[0002] In the current era of rapid development in the automotive intelligent manufacturing industry, auto parts are the core foundation of vehicle performance, safety and service life. Their processing accuracy, appearance quality and dimensional consistency directly determine the quality of the finished vehicle. With the continuous expansion of production capacity of new energy vehicles and high-end passenger vehicles, the industry has put forward stringent requirements for auto parts production, including large-scale production, high precision, zero defects and full traceability. Automated and intelligent online transmission and testing technologies have become the core necessity for upgrading the automotive auto parts production process and a key link to ensure the quality of vehicle production.

[0003] For example, patent CN112403987B, published on October 4, 2022, discloses an automotive parts forging inspection system and method. It includes an operating table with a pneumatic measuring instrument fixedly mounted on it. The pneumatic measuring instrument includes a testing platform and a measuring head fixed to the upper surface of the testing platform. A conveyor belt for transferring shaft parts to the measuring head is provided on one side of the testing platform. The conveyor belt's conveying direction is towards the measuring head. Along the conveyor belt, from the position furthest from the measuring head to the position closest to the measuring head, are sequentially arranged a cleaning mechanism for cleaning dust from the outer wall of the shaft parts, a wiping mechanism for wiping the shaft parts, and a drying mechanism for drying moisture from the outer wall of the shaft parts. A protective device is fixed above the conveyor belt. The protective cover, as described in this patent, involves placing the shaft parts on the feeding end of a conveyor belt. The shaft parts first pass through a cleaning mechanism to remove dust and other stains from their outer walls. Then, a wiping mechanism further cleans the outer walls, removing dust and moisture. Finally, a drying mechanism dries the shaft parts, ensuring their outer walls remain dry and clean. The protective cover provides better sealing throughout the process. The shaft parts are then moved from the discharge end of the conveyor belt to the measuring head for inspection. This reduces the likelihood of inaccurate test results due to foreign matter adhering to the outer walls of the shaft parts, thereby improving the accuracy of the test results.

[0004] Existing camera scanning equipment used for inspecting the appearance of parts has a fixed inspection angle and relatively fixed inspection position, which cannot perform all-round appearance inspection of parts. It requires staff to manually move and flip the parts, which greatly increases the labor intensity of the staff. Furthermore, when adjusting the position of parts, it is easy to create new bumps and knocks on the surface of the parts, affecting the quality of the parts. Summary of the Invention

[0005] The purpose of this invention is to provide an automated batch transfer and inspection device for automotive parts to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated batch conveying and inspection device for automotive parts includes an automatic conveying device for conveying parts, a liftable fixing unit on the automatic conveying device for fixing the parts to be inspected, and an inspection unit above the automatic conveying device. The inspection unit is connected to the automatic conveying device via a drive motor. When the automatic conveying device transports parts to a position directly below the inspection unit, the fixing unit lifts the parts to be inspected and raises them closer to the inspection unit. The drive motor drives the inspection unit to rotate around the parts to be inspected, thus inspecting the surface of the parts.

[0007] The aforementioned automated batch conveying and testing device for automotive parts includes a fixed unit comprising a telescopic part and a fixed part. The telescopic part is fixedly installed on the automatic conveying device, and the telescopic end of the telescopic part is connected to the fixed part. The telescopic part drives the fixed part to carry the parts to be tested to rise or fall vertically.

[0008] The aforementioned automated batch conveying and testing device for automotive parts includes a fixing frame fixedly connected to the telescopic end of the telescopic part, and the upper surface of the fixing frame is provided with a suction cup adsorption mechanism for fixing the parts to be tested.

[0009] The aforementioned automated batch conveying and testing device for automotive parts includes a fixed frame comprising a base plate connected to the telescopic part. The base plate is cross-shaped, and vertical adjusting rods are provided at the ends of the base plate. The suction cup adsorption mechanism is installed at the ends of the adjusting rods away from the base plate.

[0010] The aforementioned automated batch conveying and testing device for automotive parts includes an electrically controlled telescopic rod that can perform independent telescopic movements based on the testing requirements of the parts to be tested.

[0011] The aforementioned automated batch conveying and inspection device for automotive parts includes an inspection unit comprising a mounting side plate, a drive motor connected to the side wall of the mounting side plate, a horizontal connecting rod mounted on the mounting side plate, an inspection ring mounted on the connecting rod, and an avoidance notch provided on the inspection ring.

[0012] The aforementioned automated batch conveying and inspection device for automotive parts includes a detection ring arranged coaxially with the mounting side plate, and a detection probe is provided on the detection ring.

[0013] In the aforementioned automated batch conveying and inspection device for automotive parts, at least two inspection rings are provided, both of which are arranged side by side on the connecting rod, and the plurality of inspection rings are slidably connected to the connecting rod.

[0014] In the aforementioned automated batch conveying and inspection device for automotive parts, a bidirectional telescopic rod is also provided on the connecting rod. As the mounting side plate rotates, the bidirectional telescopic rod drives the two inspection rings to move closer to or further away from each other.

[0015] The aforementioned automated batch conveying and testing device for automotive parts includes a blower on the connecting rod. As the mounting side plate rotates, the blower synchronously blows air onto the surface of the parts to be tested, removing dirt from the surface of the parts.

[0016] The beneficial effects of the present invention are as follows: In the above technical solution, the present invention provides a batch automated conveying and testing device for automotive parts. By setting a rotatable testing unit, when the automatic conveying device transports the parts to be tested to a position directly below the testing unit, the fixing unit lifts the parts to be tested and raises them close to the testing unit. The drive motor drives the testing unit to rotate around the parts to be tested, which can inspect the appearance of the parts from all directions. It eliminates the need for workers to manually move or flip the parts, greatly reducing the workload of workers and improving the testing efficiency. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-5 The present invention will be described in further detail below.

[0021] This invention provides an automated batch conveying and inspection device for automotive parts, including an automatic conveying device 1 for conveying parts. The automatic conveying device 1 is equipped with a liftable fixing unit 2 for fixing the parts to be inspected. An inspection unit 3 is also provided above the automatic conveying device 1. The inspection unit 3 is connected to the automatic conveying device 1 via a drive motor 4. When the automatic conveying device 1 transports parts to a position directly below the inspection unit 3, the fixing unit 2 lifts the parts to be inspected and raises them closer to the inspection unit 3. The drive motor 4 drives the inspection unit 3 to rotate around the parts to be inspected, thus inspecting the surface of the parts.

[0022] Specifically, the automatic conveying device 1 is a common belt conveyor mechanism. The workers place the produced parts onto the belt conveyor mechanism, which then transports the parts to the next process for inspection (in this embodiment, the next process is the appearance inspection process), thereby completing the appearance inspection of the parts.

[0023] The shortcomings of existing technologies are that the existing camera scanning equipment used for inspecting the appearance of parts has a fixed inspection angle and a relatively fixed inspection position, which cannot perform all-round appearance inspection of parts. It requires staff to manually move and flip the parts, which greatly increases the labor intensity of the staff. Furthermore, when adjusting the position of parts, it is easy to create new bumps and knocks on the surface of the parts, affecting the quality of the parts.

[0024] To address the aforementioned issues, in this embodiment, the automatic conveying device 1 is equipped with a liftable fixing unit 2, which is used to fix the parts to be inspected. A detection unit 3 is also provided above the automatic conveying device 1. The detection unit 3 is connected to the automatic conveying device 1 via a drive motor 4. When the automatic conveying device 1 transports the parts to a position directly below the detection unit 3, the fixing unit 2 lifts the parts to be inspected and moves them closer to the detection unit 3. The drive motor 4 drives the detection unit 3 to rotate around the parts to be inspected. The detection unit 3 can inspect the appearance of the parts from all angles, eliminating the need for manual relocation or flipping operations by staff, greatly reducing workload and improving inspection efficiency.

[0025] Preferably, the fixing unit 2 includes a telescopic part 21 and a fixing part 22. The telescopic part 21 is fixedly installed on the automatic conveying device 1. The telescopic end of the telescopic part 21 is connected to the fixing part 22. The telescopic part 21 drives the fixing part 22 to carry the part to be tested to rise or fall vertically. The fixing part 22 includes a fixing frame 221 fixedly connected to the telescopic end of the telescopic part 21. The upper surface of the fixing frame 221 is provided with a suction cup adsorption mechanism 222 for fixing the part to be tested.

[0026] Specifically, in this embodiment, the telescopic part 21 is a linear telescopic rod or telescopic cylinder, etc., capable of linear extension and retraction. The suction cup adsorption mechanism 222 mainly consists of six parts: a vacuum suction cup, a vacuum generator, an air pipe, a control valve, a negative pressure detection element, and a mounting bracket. The vacuum suction cup is the actuator that directly contacts the workpiece, and is mostly made of rubber or silicone, suitable for flat and slightly curved workpieces, ensuring a sealing effect. The vacuum generator is the core device for generating negative pressure, relying on compressed air to create an airflow pressure difference. The air pipe is responsible for transporting airflow and connecting various components. The control valve is used to switch the airflow on and off, controlling the adsorption and release actions. The negative pressure detection element can monitor the vacuum level in real time to determine whether the adsorption is firm. The mounting bracket is used to fix the suction cup assembly. During operation, compressed air is introduced into the vacuum generator, utilizing the Venturi effect to form a high-speed airflow within the cavity, causing the air inside the suction cup cavity to be quickly extracted, resulting in an internal air pressure lower than [the pressure inside the suction cup]. External atmospheric pressure creates a negative pressure, which presses the workpiece tightly against the suction cup surface, achieving stable adsorption. When it is necessary to release the workpiece, the control valve switches the air path, introducing normal pressure air into the suction cup. The negative pressure inside the cavity disappears, and the internal and external air pressures return to balance, allowing the workpiece to separate from the suction cup. This suction cup adsorption mechanism 222 is existing technology, and its principle will not be elaborated upon. When the operator places the component to be tested onto the fixing frame 221, the suction cup adsorption mechanism 222 on the fixing frame 221 adsorbs the surface of the component to be tested, completing the fixation of the component. As the automatic conveying device 1 conveys the component to be tested to the position of the detection unit 3, the telescopic part 21 begins to extend. The telescopic part 21 drives the fixing frame 221, carrying the workpiece to be tested, to move towards the detection unit 3, bringing the detection unit 3 closer to the surface of the workpiece to be tested, thus improving the detection accuracy.

[0027] Obviously, since the component to be tested is fixed on the mounting bracket 221 by the suction cup adsorption mechanism 222, at least one part of the surface of the component to be tested is blocked by the suction cup adsorption mechanism 222 when it is fixed. When the detection unit 3 passes through this part, the detection unit 3 cannot detect the area blocked by the suction cup adsorption mechanism 222. As a result, there are undetected areas on the surface of the component, which require secondary inspection by the staff, increasing the workload of the staff and affecting the detection efficiency.

[0028] To solve the above problems, preferably, the fixing frame 221 includes a base plate 223 connected to the telescopic part 21. The base plate 223 is cross-shaped, and each end of the base plate 223 is provided with a vertical adjusting rod 224. The suction cup adsorption mechanism 222 is installed at the end of the adjusting rod 224 away from the base plate 223. The adjusting rod 224 is an electrically controlled telescopic rod, which can perform independent telescopic movements based on the detection requirements of the component to be tested.

[0029] Specifically, in this embodiment, because the base plate 223 is cross-shaped, the adjusting rods 224 installed at the ends of the base plate 223 are also arranged in a cross shape. When the suction cup adsorption mechanism 222 on the adjusting rod 224 adsorbs and fixes the component to be tested, the four adjusting rods 224 can ensure the stability of the component when it is fixed. When it is necessary to test the area covered by the suction cup adsorption mechanism 222, the suction cup adsorption mechanism 222 in the area to be tested is disconnected from the component, and the adjusting rod 224 on which the suction cup adsorption mechanism 222 is placed retracts downward, so that the area originally covered by the suction cup adsorption mechanism 222 is completely exposed, facilitating the testing. The detection unit 3 performs the detection. After the detection is completed, the previously retracted adjustment rod 224 extends, causing the suction cup adsorption mechanism 222 on it to re-adhere to the surface of the component and continue to adsorb the component. At the same time, the suction cup adsorption mechanism 222 on another adjustment rod 224 disconnects from the component and repeats the retraction step, exposing new areas. Multiple adjustment rods 224 and suction cup adsorption mechanisms 222 repeat the above actions until every area covered by the suction cup adsorption mechanism 222 is exposed to the detection lens of the detection unit 3, eliminating blind spots in the detection of components. This eliminates the need for secondary inspection by personnel, thereby improving detection efficiency.

[0030] Furthermore, since the adjusting rod 224 can extend and retract, when the extension heights of different adjusting rods 224 are inconsistent, the component to be inspected can be tilted, which facilitates the inspection of the back surface and gap position of the component, makes up for the limited viewing angle of the ring-shaped inspection, thoroughly eliminates defects such as minor scratches, cracks, and burrs, and improves the inspection accuracy.

[0031] Preferably, the detection unit 3 includes a mounting side plate 31, the drive motor 4 and the side wall of the mounting side plate 31, a horizontal connecting rod 32 is mounted on the mounting side plate 31, a detection ring 33 is mounted on the connecting rod 32, an avoidance notch 34 is provided on the detection ring 33, the detection ring 33 and the mounting side plate 31 are arranged coaxially, and a detection probe 35 is provided on the detection ring 33.

[0032] Specifically, when the detection unit 3 has not started detection, the clearance notch 34 is arranged downwards. When the automatic conveying device 1 transports the component to the area directly below the detection unit 3, the fixing unit 2 lifts the component to be detected and moves it closer to the detection unit 3, so that the fixing part 22 carries the component through the clearance notch 34 and moves it to the center position of the detection ring 33. Subsequently, the drive motor 4 drives the mounting side plate 31 to rotate. The mounting side plate 31 drives the detection ring 33 to rotate synchronously around the component through the connecting rod 32. During rotation, the detection probe 35 on the inner wall of the detection ring 33 detects the surface of the component and identifies the condition of the component surface, thereby completing the appearance inspection process of the component.

[0033] Obviously, some automotive parts are quite long, exceeding the shooting range of the detection probe 35. As the detection ring 33 rotates around the part, some blind spots may appear that cannot be captured by the detection probe 35, affecting the accuracy of the detection results. Therefore, at least two detection rings 33 are provided, both arranged side by side on the connecting rod 32, and multiple detection rings 33 are slidably connected to the connecting rod 32. The connecting rod 32 is also provided with a bidirectional telescopic rod 5. As the mounting side plate 31 rotates, the bidirectional telescopic rod 5 drives the two detection rings 33 to move closer or further apart.

[0034] Specifically, when inspecting long components, the two detection rings 33 rotate around the component under the drive of the drive motor 4. While rotating, the bidirectional telescopic rod 5 drives the two detection rings 33 to move away from each other. As the two detection rings 33 move away from each other, the detection range of the detection probe 35 is expanded. This avoids the generation of blind spots when inspecting long components and improves detection efficiency.

[0035] Preferably, the connecting rod 32 is also provided with a blower device, which can be a combination of a small fan and a guide pipe. The guide pipe is made of a flexible material and is used to guide the airflow from the small fan to blow onto the surface of the part to be tested (the blower device is not shown in the figure). As the mounting side plate 31 rotates, the blower device blows air onto the surface of the part to be tested to remove dirt from the surface of the part to be tested.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
