Description

Technical Field

[0001] This utility model relates to the field of oil seal inspection technology, and in particular to an oil seal appearance inspection device. Background Technology

[0002] An oil seal is a common term for general sealing components; simply put, it's a seal for lubricating oil. It's a mechanical component used to seal grease, isolating lubricated parts from power-generating parts in transmission systems to prevent lubricating oil leakage.

[0003] To ensure the quality of oil seals before they leave the factory, automated vision inspection equipment is needed to perform visual inspections. Existing automated vision inspection equipment includes a conveyor belt, a rotary table, and a CCD camera assembly. The conveyor belt transports the oil seals to the rotary table, which has multiple stations for loading, trimming, inspection, and unloading. When inspecting the oil seals, it is necessary to wait for the other stations to complete their processes before the rotary table transports the oil seals to the inspection station for the CCD camera to take pictures and inspect them.

[0004] Existing CCD cameras are typically fixed above the inspection station during installation, allowing them to inspect only the fixed positions of the inspection station. Since the inspection stations are all in fixed positions, manual adjustment of the CCD camera's position is required when inspecting different types of oil seals, resulting in long switching times.

[0046] Please see Figures 1 to 4 As shown, this embodiment provides an oil seal appearance inspection device, which includes a conveying mechanism (not shown), a loading mechanism 10, an inspection platform 20, a driving mechanism 30, and a camera assembly 40. The conveying mechanism has a loading station on its conveying path and is configured to convey the oil seal to be inspected to the loading station. The loading mechanism 10 is located on the side of the loading station and is configured to pick up the oil seal to be inspected from the loading station and transport the picked-up oil seal to the inspection platform 20. The camera assembly 40 is located above the inspection platform 20 and is configured to take pictures of the oil seal on the inspection platform 20 and perform appearance inspection on the oil seal based on the acquired images. The driving end of the driving mechanism 30 is connected to the camera assembly 40, and the driving mechanism 30 is at least configured to drive the camera assembly 40 to move laterally and vertically, so as to move the camera assembly 40 closer to or away from the inspection platform 20.

[0047] As can be seen, by linking the conveying mechanism, the feeding mechanism 10 and the camera assembly 40, the entire process of oil seal conveying, feeding and testing is automated. The camera assembly 40, together with the drive mechanism 30, can accurately locate the detection position, reduce the switching time and improve the detection efficiency.

[0048] In one embodiment, the drive mechanism 30 is also configured to drive the camera assembly 40 to rotate. The drive mechanism 30 includes a vertical plate 31, a lifting module 32, a lifting plate 33, a horizontal moving module 34, a horizontal moving plate 35, a rotation module 36, and a rotation frame 37. The lifting module 32 is vertically mounted on the vertical plate 31, and the drive end of the lifting module 32 is connected to the lifting plate 33. The lifting plate 33 is vertically mounted on the vertical plate 31, and the lifting module 32 is configured to drive the lifting plate 33 to move up and down. The horizontal moving module 34 is horizontally mounted on the lifting plate 33, and the drive end of the horizontal moving module 34 is connected to the horizontal moving plate 35. The horizontal moving module 34 is configured to drive the horizontal moving plate 35 to move horizontally. The rotation module 36 is mounted on the horizontal moving plate 35, and the drive end of the rotation module 36 is connected to the rotation frame 37. The camera assembly 40 is mounted on the rotation frame 37, and the rotation module 36 is configured to drive the rotation frame 37 to rotate by a preset angle.

[0049] Specifically, the lifting module 32 and the traversing module 34 are ball screw type linear modules or synchronous belt type 144 linear modules.

[0050] Specifically, the rotating module 36 is a rotary cylinder or a servo motor.

[0051] As can be seen, the combination of the lifting module 32, the horizontal moving module 34 and the rotating module 36 enables the camera assembly 40 to move and rotate in the vertical and horizontal directions, which can adapt to the detection of various types of oil seals and has a wide range of applications.

[0052] In one implementation, the camera assembly 40 includes a camera 41 and a fill light 42. The camera 41 is mounted on the first end of the rotating frame 37 with the shooting end of the camera 41 facing downwards. The fill light 42 is mounted on the rotating frame 37 and is located in the shooting path of the camera 41. The fill light 42 is configured to provide fill light when the camera 41 is shooting.

[0053] Specifically, the fill light 42 is a ring light source.

[0054] As can be seen, the supplementary light 42 provides uniform illumination when the camera 41 takes pictures, eliminating reflections or shadows on the oil seal surface, ensuring image clarity, and improving detection quality.

[0055] In one embodiment, a first guide component 38 is provided between the lifting plate 33 and the upright plate 31. The first guide component 38 includes a first linear guide rail and a first slider. The first linear guide rail is installed on the upright plate 31 in a vertical direction. The first slider is slidably mounted on the first linear guide rail in a vertical direction and is fixedly connected to the lifting plate 33.

[0056] As can be seen, the guiding structure of the first linear guide rail and the slider restricts the swaying and offset of the lifting plate 33, ensures the verticality of the camera 41 when it moves in the vertical direction, and improves the stability of the camera 41 when it moves.

[0057] In one embodiment, the feeding mechanism 10 includes a frame 11, a tilting frame 12, a clamping assembly 13, and a tilting drive assembly 14. The tilting frame 12 is rotatably mounted on the frame 11. The drive end of the tilting drive assembly 14 is connected to the tilting frame 12. The tilting drive assembly 14 is configured to drive the tilting frame 12 to rotate. The clamping assembly 13 is disposed on the tilting frame 12 and is configured to clamp or release the oil seal to be tested.

[0058] As can be seen, through the cooperation of the flipping frame 12, the clamping assembly 13 and the flipping drive assembly 14, the oil seal is picked up from the conveying mechanism and directly transported to the inspection platform 20 for appearance inspection. The appearance inspection of the oil seal can be carried out without waiting for the subsequent process to be completed, which improves the loading efficiency of the oil seal and thus improves the inspection efficiency.

[0059] In one embodiment, the clamping assembly 13 includes a drive member 130, a first gripper 131, and a second gripper 132, wherein:

[0060] The fixed end of the drive member 130 is disposed on the flipping frame 12, and the drive end of the drive member 130 is connected to the first gripper 131 and / or the second gripper 132. The drive member 130 is configured to drive the first gripper 131 and the second gripper 132 to move closer or further away from each other in a first direction to clamp or release the oil seal to be tested.

[0061] As can be seen, by controlling the opening and closing of the two grippers through the drive component 130, the clamping force can be precisely adjusted, which can ensure that the oil seal does not fall off during transportation and avoid deformation and damage to the oil seal due to excessive clamping force.

[0062] In one embodiment, the drive component 130 includes a cylinder and a guide assembly. The cylinder body is fixedly mounted on the tilting frame 12, and the drive end of the cylinder is connected to the first gripper 131 and the second gripper 132. Guide assemblies are provided between the first gripper 131 and the tilting frame 12 and between the second gripper 132 and the tilting frame 12. The guide assemblies are configured to guide the movement of the first gripper 131 and the second gripper 132 in a first direction.

[0063] It can be seen that by setting the guide component, the smooth movement of the first gripper 131 and the second gripper 132 is achieved, thereby improving the stability and reliability of the gripping of the first gripper 131 and the second gripper 132.

[0064] In one embodiment, the flipping drive assembly 14 includes a first motor 140 and a transmission assembly 141. Both ends of the flipping frame 12 along a first direction are rotatably mounted on the frame 11 via rotating shafts. The fixed end of the first motor 140 is mounted on the frame 11. The drive end of the first motor 140 is connected to the first end of the transmission assembly 141, and the second end of the transmission assembly 141 is connected to the rotating shaft at one end of the flipping frame 12. The transmission assembly 141 includes a first synchronous pulley 142, a second synchronous pulley 143, and a synchronous belt 144. The first synchronous pulley 142 is coaxially connected to the rotating shaft at one end of the flipping frame 12. The second synchronous pulley 143 is rotatably mounted on the frame 11 and located below the first synchronous pulley 142. The drive shaft of the first motor 140 is coaxially connected to the second synchronous pulley 143, and the synchronous belt 144 is sleeved on the first synchronous pulley 142 and the second synchronous pulley 143.

[0065] As can be seen, through the cooperation of the first synchronous pulley 142, the second synchronous pulley 143, the synchronous belt 144, and the first motor 140, a transmission component 141 with simple structure, high conveying efficiency, and high conveying accuracy is provided.

[0066] In one implementation, the testing platform 20 includes a platform 21 and a lifting assembly 22. The lifting assembly 22 includes a frame 11, a second motor, a ball screw, and a screw nut. The ball screw is vertically mounted on the frame 11 and can rotate along its own axis. The screw nut is sleeved on the ball screw and is fixedly connected to the platform 21. The shaft of the second motor is connected to the ball screw for transmission. The second motor is configured to drive the ball screw to rotate along its own axis. The second motor drives the ball screw to rotate, thereby driving the screw nut to rise and fall, and thus driving the platform 21 to rise and fall.

[0067] As can be seen, the lifting function can adjust the height of the testing platform 20 to accommodate different types of oil seals, thereby enabling testing with testing equipment and improving the adaptability of the testing platform 20.

[0068] As one implementation method, the detection platform 20 is provided with a sensing component 50, which is used to detect whether there is an oil seal on the detection platform 20, and then control the lifting component 22 to work.

[0069] Specifically, the sensing component 50 includes a transmitter and a receiver, which are symmetrically arranged on both sides of the detection platform 20. The transmitter is used to emit a light beam, and the receiver is used to receive the light beam emitted by the transmitter. When there is an oil seal on the detection platform 20, the oil seal will block the light beam emitted by the transmitter; otherwise, the receiver will receive the light beam emitted by the transmitter.

[0070] As can be seen, the sensing component 50 monitors the platform for oil seals in real time, and the lifting component 22 is triggered only when an oil seal is detected, thus avoiding the platform from lifting or lowering without a load or malfunctioning, and improving the intelligence and efficiency of the process.

[0071] The working principle of the above-mentioned oil seal appearance inspection device is as follows:

[0072] S1, the flip drive assembly 14 drives the clamping assembly 13 to rotate to the first position so as to clamp the oil seal to be tested on the conveying mechanism through the clamping assembly 13;

[0073] S2, the flipping drive assembly 14 drives the clamping assembly 13 and the oil seal to be tested held by the clamping assembly 13 to move to the second position, so as to release the oil seal to be tested onto the testing platform 20 located at the receiving station through the clamping assembly 13;

[0074] S3, the lifting assembly 22 drives the testing platform 20 to rise or fall, so as to move the oil seal from the receiving station to the testing station;

[0075] S4, the drive mechanism 30 drives the camera 41 to a suitable shooting position, and takes pictures of the oil seal on the inspection station through the camera 41 to carry out appearance inspection of the oil seal.

[0076] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0077] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples.
