[0023] Please continue reading. Figure 1 In this embodiment, the first lifting mechanism 12 is located on the conveyor belt directly below the working range of the oiling robotic arm 11. When the carrier is driven to the working area of ​​the oiling robotic arm, the first lifting mechanism acts on the support plate 122 through the drive mechanism 123. The support plate 122 can smoothly lift the object to be oiled from the flow position of the conveyor belt to the first predetermined position, so that the oiling nozzle 161 can inject oil into the object. The second lifting mechanism 13 is located on the conveyor belt directly below the working range of the oiling detection platform 14 and has the same structure as the first lifting mechanism 12. When the carrier 15 is driven to the working area of ​​the oiling detection platform 14, the second lifting mechanism acts on the support plate 122 through the drive mechanism 123. The support plate 122 can lift the carrier 15 containing the oiled object to the second predetermined position, so that the oiling detection platform 14 can identify and detect the oiling status inside the object.

[0024] Please see Figure 4aIn this embodiment, the first lifting mechanism 12 and the second lifting mechanism 13 have the same structure, both including a support plate 122 and a drive mechanism 123. At least one positioning pin 126 is provided on the upper surface of the support plate 122 of the lifting mechanism for positioning and fixing the transported vehicle 15, ensuring that the vehicle 15 will not shift or fall off during the lifting process. The lifting mechanism can control the rise or fall of the support plate 122 at the upper end of the lifting mechanism via the drive mechanism 123. The bottom of the lifting mechanism is a base plate 121. Four support columns 124 are provided at the four corners of the upper surface of the base plate 121. The upper ends of the support columns 124 are connected to a cylinder mounting plate 127. The cylinder mounting plate 127 has a groove on the side facing the same direction of travel as the vehicle 15, and at least one through hole is provided at each of its four corners connected to the support columns 124. The drive mechanism 123 is installed inside the lifting mechanism, located between the support plate 122 and the base plate 121. It includes a cylinder 1231 and a piston rod 1232. The cylinder 1231 is embedded below the cylinder mounting plate 127, and the piston rod 1232 passes through the central through hole of the cylinder mounting plate and is fixedly connected to the support plate 122. The support plate 122 has grooves on both sides, and its lower surface is connected to multiple guide posts 128. The guide posts 128 pass through the cylinder mounting plate 127 via straight bearings, and their lower ends are connected in pairs via a connecting block 120. The connecting block 120 is equipped with a buffer assembly 129 for buffering and protection during the lifting process.

[0025] Please see Figure 4b In this embodiment, the buffer assembly 129 includes a first buffer element 1291 and a second buffer element 1292. The first buffer element 1291 is disposed on a connecting block inside the lifting mechanism. A through hole is opened in the center of the connecting block, through which the first buffer element 1291 passes and is fixed to the connecting block. A corresponding through hole is also opened on the base plate 121, through which the lower end of the first buffer element 1291 can pass. The second buffer element 1292 is disposed on the lower surface of the cylinder mounting plate 127, and its position corresponds to that of the first buffer element 1291. When the lifting mechanism is in the lifting state, the first buffer element 1291 rises along with it, and its upper end can contact the second buffer element 1292, thus playing a buffering role, preventing excessive impact force from damaging the mechanical components, reducing wear and extending service life.

[0026] Please see Figure 5a and 5b In this embodiment, the oil filling detection platform 14 is located on the same side as the oil filling robotic arm 11. An imager 142 is mounted on the upper end of the oil filling detection platform 14, capable of capturing images of the interior of the object being oiled and identifying the captured images to check the oil filling status inside the object. The imager 142 is connected to the bracket 141 via a multi-dimensional adjustment mechanism 145, which allows for capturing images from different positions, adapting to the needs of identifying and detecting products of different shapes and specifications.

The light source plate 143 is fixedly connected to the rectangular frame through a light source connecting plate 144, which is used to provide a uniform and bright lighting environment for image acquisition, so as to ensure shadow-free illumination of the interior of the object being oiled. A viewing hole is provided at the center of the light source plate 143, which is the viewing channel of the imager 142. The imager 142 can take pictures of the object being oiled below the light source plate 143 through the viewing hole to identify its internal oil filling status. The imager 142 includes an optical lens 1421 and an image acquisition module 1422. The optical lens 1421 is mounted at the lower end of the image acquisition module 1422 and faces the viewing hole at the center of the light source plate 143. The image acquisition module 1422 is fixedly connected to the bracket 141 through a multi-dimensional adjustment mechanism 145. The camera 142 can move horizontally and vertically via the multi-dimensional adjustment mechanism 145, making it easy to change lenses and adjust the shooting position, and is suitable for inspecting products of different shapes and specifications.

[0028] Please continue reading. Figure 5a and 5b In this embodiment, the bracket 141 includes a vertical bracket 141, a horizontal bracket 141, and a rectangular frame. The horizontal bracket 141 is disposed on the upper end of the vertical bracket 141. A first triangular fixing block is provided at the lower end of the horizontal bracket 141, with one corner connected to the surface of the horizontal bracket 141 and the other corner connected to the surface of the vertical bracket 141, for supporting and fixing the horizontal bracket 141. The rectangular frame is fixed to the side of the horizontal bracket 141 by two second triangular blocks, allowing the end of the horizontal bracket 141 to be located directly above the center of the rectangular frame, facilitating the installation of the camera 142 at the end.

[0029] Please see Figure 6aIn embodiments 6b and 6c, the multi-dimensional adjustment mechanism 145 includes a first mounting block 1451. The side of the camera 142 is fixedly connected to the first mounting block 1451. The first mounting block 1451 is fixedly connected to the side of the second mounting block 1453 via a horizontally arranged first adjusting bolt 1452 and a first fixing block 1455. By adjusting the first adjusting bolt 1452, the first mounting block 1451 can be moved horizontally, thereby moving the camera 1421 horizontally. The second mounting block 1453 is fixedly connected to the upper end of the bracket 141 via a vertically arranged second adjusting bolt 1454 and a second fixing block 1456. By adjusting the second adjusting bolt 1454, the second mounting block 1453 can be moved vertically, thereby moving the camera 1421 vertically. The first fixing block 1455 and the second fixing block 1456 have U-shaped slots, which are used to clamp the first adjusting bolt 1452 and the second adjusting bolt 1454, respectively.

[0030] Please combine Figure 7 See Figure 1 In this embodiment, the automatic oiling device 10 also includes a carrier 15 and a transmission belt for transporting the carrier 15. When oiling, the object to be oiled is placed in the receiving fixture 153 on the carrier 15, and the carrier 15 is placed on the transmission belt. When the carrier 15 is transported to the area of ​​the first lifting mechanism, the carrier 15 is lifted to the first predetermined position by the first lifting mechanism, and the oiling nozzle 161 injects oil into the interior of the object to be oiled. When the carrier 15 is transported to the area of ​​the second lifting mechanism 13, the carrier 15 is lifted to the second predetermined position by the second lifting mechanism 13, and the camera 142 photographs and identifies the oiling situation inside the object to be oiled.

[0031] Please continue reading. Figure 7 In this embodiment, the carrier 15 includes a first carrier 151, the upper surface of which is provided with at least one receiving fixture 153. A clamping mechanism 154 is provided adjacent to the receiving fixture 153 for clamping and fixing the oil-filled object within the receiving fixture 153. During production, the carrier 15 can be equipped with one or more receiving fixtures 153 as needed to accommodate multiple objects, or an object comprising multiple components, to meet the production requirements of different objects. The carrier 15 also includes a second carrier 152. The first carrier 151 and the second carrier 152 are stacked vertically and attracted to each other by magnets. The lower surface of the first carrier 151 and the upper surface of the second carrier 152 are provided with multiple corresponding magnets. The magnetic attraction ensures a tight bond between the first carrier 151 and the second carrier 152, providing stability during transport. When the carrier 15 needs to be replaced due to production requirements or the assembly process needs to be adjusted according to different product specifications, the magnetic attraction allows for convenient disassembly of the first carrier 151 and the second carrier 152.

[0032] Please continue reading. Figure 7 The upper surface of the carrier 15 shown is provided with a clamping mechanism 154 and a limiting mechanism 155. The clamping mechanism 154 uses an elastic element to clamp the assembled object, and the limiting mechanism 155 includes a limiting elastic element to elastically limit the cable. Therefore, when the object to be oiled is finished being oiled, it can be pulled upwards by the gripper of the robotic arm to break free from the elastic fixation of the clamping mechanism 154 and the limiting mechanism 155.

[0033] Please see Figure 8a In this embodiment, the oil injection mechanism 16 includes a base plate 162 for supporting other components of the oil injection mechanism 16. An oil reservoir 160 is mounted on the bottom support plate 162, with its bottom fixedly connected to the bottom support plate 162. The upper end of the oil reservoir 160 has an opening flush with the side wall of the oil reservoir 160 for storing injected oil. Telescopic rod assemblies are located on both sides of the oil reservoir 160. Each telescopic rod assembly includes a telescopic rod 163 and a cylinder 164. The lower end of the cylinder 164 is fixedly connected to the bottom support plate 162, and the telescopic rod 163 is capable of lifting and lowering. A support plate 165 is mounted on the upper end of the telescopic rod 163, and the two telescopic rod assemblies are fixedly connected to the support plate 165 by bolts. An oil injection regulator 166 is mounted on one end of the support plate 165 for adjusting the amount of oil injected into the object being oiled. The other end of the support plate 165 is provided with a first sensing plate 167, and a second sensing plate 168 is provided on the side of the cylinder 164 on the same side as the first sensing plate 167. The first sensing plate 167 can work in conjunction with the second sensing plate 168 to detect the working status of the oil injection device 10. The middle end of the support plate 165 has a through hole, the shape and size of which correspond to the oil suction pipe at the lower end of the oil suction device 169. The lower end of the oil suction device passes through this through hole and connects to the oil reservoir cover. The other end of the oil suction device 169 is connected to the oil injection nozzle 161 through an oil delivery pipe to form an oil passage.

[0034] Please see Figure 8b In this embodiment, the oil injection mechanism 16 can check the working status of the oil injection device 10 and detect the amount of oil stored in the oil reservoir 160 through the first sensor 167 and the second sensor 168. The first sensor 167 is disposed at one end of the support plate 165, and the second sensor 168 is disposed at one end of the telescopic rod assembly on the same side. When the support plate 165 moves up and down with the telescopic rod 163, the oil extraction device 169 and the first sensor on the support plate 165 move up and down. The lower end of the oil extraction device 169 contacts the liquid surface of the oil stored in the oil reservoir 160 and descends with the liquid level. When the oil stored in the oil reservoir 160 is exhausted, the first sensor 167 and the second sensor 168 contact each other to detect the oil, thereby reminding that it needs to be replenished.
