[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figure 1 , Figure 1 This is a schematic diagram of installing a support ring into a groove of a guide sleeve shaft hole in the prior art.

[0031] See also Figure 2-10 The present invention provides an automatic assembly device for a support ring in a hydraulic cylinder guide sleeve shaft hole, comprising a feeding device 1, a loading device 2, a transmission device 3, an assembly device 4 and a controller.

[0032] The feeding device 1 has the functions of storing materials, switching the support ring model at any time, discharging materials in sequence and positioning and docking with the feeding device 2. The function of the feeding device 2 is to identify the opening direction of the support ring provided by the feeding device 1, and place it at the end of the guide sleeve hole in a specific posture. The function of the transmission device 3 is to accurately position the guide sleeve on the tray 32 at the loading position and the assembly position respectively, and cooperate to complete the loading and assembly actions of the support ring. In order to ensure the precise positioning of the guide sleeve, the transmission system should have the dual guarantees of drive control and mechanical positioning. The function of the assembly device 4 is to press the support ring placed on the guide sleeve in a specific posture into the groove, and then detect and feedback whether the support ring is assembled in place.

[0033] The feeding device 1 includes a turntable 11, a material rack 12, a loading platform 13, an ejection mechanism 14 and a table 15. The material rack 12 is fixed on the turntable 11. The turntable 11 is rotated by a motor and is set on the table 15. The loading platform 13 is set at the bottom of the material rack 12. The ejection mechanism 14 is set at the bottom of the loading platform 13. The ejection mechanism 14 includes a third cylinder 141 and a push plate 142. The third cylinder 141 is fixed to the bottom of the loading platform 13, and the push plate 142 is fixed to the output end of the third cylinder 141.

[0034] See also Figure 2 and 3 The motor can drive the turntable 11 to rotate, and then the turntable 11 drives the material rack 12 to rotate. In this embodiment, each turntable 11 is provided with eight material racks 12 with different diameters to store support rings of different sizes. When a certain specification of support rings needs to be assembled, the turntable 11 rotates the set material rack 12 to the discharge port of the loading platform 13. In this process, the snap ring at the bottom of the material rack 12 falls off through the tripping mechanism, and the snap ring is reinstalled on the rotating material rack 12 through the buckling mechanism to prevent the unused support ring from falling. Then the third cylinder 141 is actuated to drive the push plate 142 to push the fallen support ring out of the loading platform 13, which is convenient for the loading device 24 to clamp it.

[0035] It should be noted that the snap ring, the release mechanism and the buckle mechanism in this embodiment are technical means well known to those skilled in the art, and the specific structure and working principle of the release mechanism and the buckle mechanism will not be described in detail here.

[0036] The loading device 2 includes a collaborative robot 21 , a visual camera 22 and an electric gripper 23 . The electric gripper 23 is disposed at the end of the collaborative robot 21 , and the visual camera 22 is installed at one end of the collaborative robot 21 .

[0037] See also Figure 2 and 4When the end of the collaborative robot 21 drives the electric gripper 23 to move to the material picking position of the feeding device 1, the visual camera 22 first takes a picture to identify the opening position on the support ring, and then the shaft at the end of the collaborative robot 21 rotates according to the calculated value, and aligns the fingertips of the electric gripper 23 with the specific position of the support ring to clamp it, and then takes the support ring 1 to the loading position and presses the support ring into the guide sleeve hole in the set posture.

[0038] The transmission device 3 includes a transmission line 31 and a tray 32. The tray 32 is placed on the transmission line 31. The transmission device 3 also includes a positioning mechanism 33. The positioning mechanism 33 includes a second cylinder 331 and a guide rod 332. The second cylinder 331 is fixed to the inside of the transmission line 31. The guide rod 332 is fixed to the output end of the second cylinder 331. A positioning hole matching the guide rod 332 is provided at the bottom of the tray 32. The transmission line 31 is composed of two symmetrical belt conveyors 311. The tray 32 is placed on the conveyor belt surface of the two belt conveyors 311.

[0039] See also Figure 2 and 5 The conveyor belt 311 carries the pallet 32 to the loading position, and the second cylinder 331 under the pallet 32 at the loading position is actuated, driving the guide rod 332 to move upward and extend into the positioning hole to realize the positioning of the pallet 32, thereby accurately positioning the position of the guide sleeve. Then the collaborative robot 21 accurately places the clamped support ring into the axial hole of the guide sleeve, and the lower guide rod 332 retracts at this time. The conveyor belt 311 continues to transport the pallet 32 forward to the assembly position, and the second cylinder 331 under the pallet 32 at the assembly position is actuated. At this time, the pallet 32 is positioned again. After the assembly device 4 assembles the support ring into place, the second cylinder 331 under the assembly position drives the guide rod 332 to retract, and the transmission device 3 continues to transport the pallet 32 to the next workstation.

[0040] The assembly device 4 includes a bracket 41, a first cylinder 42, an adapter plate 43 and a tooling 44. The bracket 41 is fixed on the transmission line 31, the first cylinder 42 is installed on the surface of the bracket 41, the adapter plate 43 is fixed to the output end of the first cylinder 42, and the tooling 44 is arranged on the surface of the adapter plate 43. The tooling 44 is arranged in a pagoda-shaped structure.

[0041] See also Figure 2 、 5 And 6, when the tray 32 reaches the assembly position, the first cylinder 42 drives the adapter plate 43 to move downward, and the adapter plate 43 drives the tooling 44 to move downward. When the tooling 44 moves downward, its bottom squeezes the support ring in the axial hole of the guide sleeve, thereby pressing the support ring into the internal groove of the guide sleeve. Since the tooling 44 is set to a pagoda-shaped structure, the tooling 44 can adapt to guide sleeves of different sizes by controlling the pressing depth during the pressing process.

[0042] The turntable 11 , the third cylinder 141 , the second cylinder 331 , the collaborative robot 21 , the visual camera 22 , the electric gripper 23 , the belt conveyor 311 and the first cylinder 42 are all electrically connected to the controller.

[0043] It should be noted that, in this embodiment, please refer to Figure 7 、 8 , 9 and 10, the controller is a PLC, which is used to control the automatic movement of the turntable 11, the third cylinder 141, the second cylinder 331, the collaborative robot 21, the visual camera 22, the electric gripper 23, the belt conveyor 311 and the first cylinder 42, and is also used to cooperate with the feedback of the visual camera 22 so that the support ring can be accurately placed in the axial hole of the guide sleeve in a specific posture, and in order to input parameters and obtain specific data, a touch screen can be connected to the device and connected to the controller to play the role of issuing instructions and obtaining feedback.

[0044] Example 2

[0045] In this embodiment, the assembly device 4 can be integrated into the loading station of the transmission line 31. After the collaborative robot 21 places the support ring into the guide sleeve, it switches to the assembly device 4. Then, the collaborative robot 21 moves to press the support ring into the installation groove of the guide sleeve shaft hole to complete the automatic assembly of the support ring.
