[0040] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.
[0041] Please refer to Figure 1 and Figure 2 As shown, this embodiment discloses a transmission oil filter inspection device, including a rotating mechanism 100, a supplementary lighting mechanism 200, and a vision inspection module 300. The rotating mechanism 100 includes a rotating part 110 and a limiting part 120. The limiting part 120 is adapted to limit the housing so that the housing and the rotating part 110 are dynamically coupled. The supplementary lighting mechanism 200 includes a supplementary light 210, which is coaxially arranged with the rotating shaft of the rotating part 110 and can be inserted into the housing. The vision inspection module 300 is located on one side of the axis of the rotating part 110, and the detection field of the vision inspection module 300 faces the housing.
[0042] According to the transmission oil filter inspection device of this utility model embodiment, the transmission oil filter is sleeved on the outside of the supplementary light 210. The limiting part 120 dynamically couples the transmission oil filter with the rotating part 110, so that the transmission oil filter rotates under the drive of the rotating part 110. The vision inspection module 300 acquires the surface information of the transmission oil filter during the rotation of the transmission oil filter to determine whether the transmission oil filter is qualified.
[0043] It should be noted that transmission oil filters typically have a barrel-shaped housing with filter holes. The inner wall of the housing and the filter holes are covered with a filter screen. Defects in the transmission oil filter (insufficient material, shrinkage, leaks, cracks, etc.) affect its performance and usually require manual visual inspection, which is inefficient. While automated inspection solutions using vision cameras to capture images of the transmission oil filter typically use supplementary lighting rings on the inspection field of view of the vision inspection camera, this solution does not effectively help the vision inspection camera obtain the internal detailed structure of the filter screen.
[0044] According to the transmission oil filter inspection device of this utility model embodiment, the transmission oil filter is driven to rotate by the rotating part 110, and the automatic inspection of 360-degree appearance is achieved by combining the vision inspection module 300. Furthermore, during the inspection process, the supplementary light 210 inserted into the housing is used to supplement the filter screen to display the detailed structure of the filter screen, which effectively avoids the problem of poor supplementary lighting effect when using an external supplementary light ring and improves the inspection accuracy.
[0045] In this embodiment, the rotating part 110 may be in the form of a stepper motor or a servo motor.
[0046] In this embodiment, the supplementary light 210 can be fixed to the rotating part 110. That is, when the gearbox oil filter is installed to the rotating part 110, it needs to be first fitted to the supplementary light 210. Of course, the supplementary light 210 can also be independent of the rotating part 110, as will be explained in detail later.
[0047] In some embodiments, combined with Figure 1 and Figure 2 As shown, the supplementary lighting mechanism 200 also includes a supplementary lighting drive 220. The supplementary light 210 can extend and retract along the axis of the rotating part 110 under the drive of the supplementary lighting drive 220 to be inserted into the housing. The rotating part 110 is provided with a clearance hole, which is suitable for the supplementary light 210 to pass through.
[0048] In this embodiment, after the transmission oil filter is dynamically coupled to the rotating part 110, the auxiliary light drive 220 drives the auxiliary light 210 to move along the axis of the rotating part 110 and pass through the clearance hole into the housing of the transmission oil filter. By providing a retractable auxiliary light 210, the transmission oil filter will not collide with the auxiliary light 210 during the process of being fed to the rotating part 110, effectively protecting the auxiliary light 210.
[0049] In this embodiment, the supplementary lighting drive 220 is a cylinder; in other embodiments, it can also be a lead screw module, a slide module, etc.
[0050] In some embodiments, combined with Figure 1 and Figure 2As shown, the limiting part 120 includes a limiting pressure head 121 and a limiting drive member 122. The limiting pressure head 121 can move along the axial direction of the rotating part 110 under the drive of the limiting drive member 122. The limiting part 120 is adapted to press against the first end of the housing, and the rotating part 110 is adapted to be dynamically coupled to the second end of the housing.
[0051] In this embodiment, the limiting pressure head 121 first moves away from the rotating part 110 under the drive of the limiting drive member 122, so that there is enough space for the transmission oil filter element to pass through between the limiting pressure head 121 and the rotating part 110. After the second end of the housing of the transmission oil filter element is aligned with the rotation center of the rotating part 110, the limiting drive member 122 drives the limiting pressure head 121 to approach the rotating part 110 until it presses against the first end of the housing, so that the transmission oil filter element and the rotating part 110 are dynamically coupled.
[0052] In this embodiment, the limiting pressure head 121 and the rotating part 110 are located at both ends of the housing to support both ends of the housing, ensuring the rotational stability of the housing during rotation.
[0053] In this embodiment, the limiting drive component 122 is a cylinder; in other embodiments, it can also be a lead screw module, a slide module, etc.
[0054] In other embodiments, the limiting part 120 can also be in the form of a gripper, such as a gripper provided on the rotating part 110, the gripper fastening to the outside of the housing to fix it to the rotating part 110; it can also be in the form of a vacuum hole, such as a vacuum hole provided on the surface of the rotating part 110 that fits against the housing to adsorb the housing and fix the housing to the rotating part 110.
[0055] In some embodiments, combined with Figures 1 to 4 As shown, the transmission oil filter inspection equipment also includes a loading mechanism 400 and a conveying mechanism 500, with the conveying mechanism 500 connected to the loading mechanism 400 and the rotating mechanism 100. The entire loading and inspection process requires no manual operation, effectively improving the inspection efficiency of the transmission oil filter.
[0056] In this embodiment, the handling mechanism 500 includes a robotic arm to achieve flexible handling in three-dimensional space. In other embodiments, the handling mechanism 500 may also be a combination of several linear motion modules.
[0057] In some embodiments, combined with Figures 1 to 4 As shown, the conveying mechanism 500 includes a first conveying gripper 510, which is movable relative to the rotating mechanism 100 and is suitable for gripping and conveying the transmission oil filter element; the transmission oil filter element inspection device also includes a vision positioning module 600, which is suitable for obtaining the position information of the transmission oil filter element gripped by the first conveying gripper 510, so that the first conveying gripper 510 can adjust the position of the transmission oil filter element.
[0058] In this embodiment, the first transport gripper 510 picks up the transmission oil filter element from the loading mechanism 400 and moves it to the vision positioning module 600. The vision positioning module 600 acquires the position information of the transmission oil filter element relative to the first transport gripper 510, and adjusts the movement trajectory of the first transport gripper 510 based on the position information, so that the transmission oil filter element can be stably fed to the rotating mechanism 100. By setting the vision positioning module 600, the movement path of the first transport gripper 510 can be dynamically planned for the position of each transmission oil filter element, effectively improving the feeding stability of the transmission oil filter element.
[0059] In some embodiments, combined with Figures 1 to 4 As shown, the transmission oil filter element inspection device also includes an OK unloading frame 710, and an opening of the OK unloading frame 710 is provided below the end of the rotating part 110 that cooperates with the housing.
[0060] In this embodiment, the qualified transmission oil filter element detected in the rotating mechanism 100 automatically falls into the OK unloading frame 710 after the limiting part 120 is released, thereby improving the detection efficiency.
[0061] In some embodiments, combined with Figures 1 to 4 As shown, the transmission oil filter element inspection equipment also includes an NG unloading frame 720, the opening of which is located below the detection field of view of the vision positioning module 600; the conveying mechanism 500 includes a second conveying gripper 520, which is adapted to hold transmission oil filters that fail the inspection.
[0062] In this embodiment, after the second transport gripper 520 clamps the defective transmission oil filter element, it does not move above the NG unloading frame 720, but moves to the loading mechanism 400, where the first transport gripper 510 grabs the next transmission oil filter element to be inspected. The first transport gripper 510 and the second transport gripper 520 move synchronously to the vision positioning module 600. While the position information of the transmission oil filter element to be inspected on the first transport gripper 510 is acquired, the second transport gripper 520 releases, and the defective transmission oil filter element falls into the NG unloading frame 720.
[0063] In this embodiment, by using the second transport gripper 520 to transport the unqualified transmission oil filter element, and in conjunction with the position of the NG unloading frame 720, the acquisition of the position information of the transmission oil filter element to be tested and the collection of the unqualified transmission oil filter element are carried out simultaneously, effectively reducing the running trajectory length of the transport mechanism 500 and improving the testing efficiency.
[0064] In some embodiments, combined with Figure 1 and Figure 3As shown, the loading mechanism 400 includes a loading tray 410 and a feeding vision module 420. The feeding vision module 420 is located above the loading tray 410 and is suitable for detecting the position information of the transmission oil filter element in the loading tray 410. This ensures that the conveying mechanism 500 can accurately pick up the transmission oil filter element in the loading tray 410.
[0065] In other embodiments, the feeding method of the material loading mechanism 400 can also be in the form of a vibrating feeding plate combined with a feeding track, with the gearbox oil filter moving sequentially along the feeding track.
[0066] In some embodiments, the loading tray 410 is a flexible vibrating tray. The vibration of the flexible vibrating tray avoids the stacking of transmission oil filter elements in the loading tray 410, which helps the feeding vision module 420 to determine the position of each transmission oil filter element. Furthermore, the flexible vibration will not affect the structure of the transmission oil filter element, especially the filter screen.
[0067] On the other hand, this utility model embodiment also provides a transmission oil filter production line, including the transmission oil filter inspection equipment as described in the above embodiment.
[0068] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
