Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0018] In the engine block assembly process, a final assembly is required, which involves merging and securing the two side panels or upper and lower side panels together to form a complete engine block. This process requires applying adhesive to the connecting surfaces and using fasteners for securing them. Because engine block specifications vary, different types of fasteners are used, and due to limitations in installation location, each type of engine block requires multiple sizes of fasteners for fixation. Currently, fasteners for engine blocks are typically installed manually. This requires not only sorting the fasteners but also installing them to their designated positions on the engine block, resulting in high labor intensity and low efficiency.

[0019] Based on this, an exemplary embodiment of this application provides an automatic sorting and installation device for engine housing fasteners based on a five-star gripper. By combining a vibration sorting device with a vision guidance unit, fasteners of different specifications and lengths can be quickly identified and separated. By setting a five-star gripper assembly, the radially arranged gripper assembly can simultaneously clamp multiple fasteners and accurately locate the mounting holes of the engine housing under visual guidance, thereby shortening the installation time and improving the installation efficiency.

[0020] An exemplary embodiment of this application provides an automatic sorting and installation device for engine housing fasteners based on a five-star gripper, such as... Figure 1 As shown, the equipment includes a vibration sorting device, a robotic gripper, and a vision guidance unit 30. A conveyor line (not shown) is provided on one side of the robotic gripper, on which an engine housing is transported. Preferably, the engine housing is placed in a tray for securing it. A lifting mechanism is provided on the conveyor line; when the tray moves above the lifting mechanism, the lifting mechanism can lift the tray for positioning. A vibration sorting device is provided on the other side of the robotic gripper. Vision guidance units 30 are provided above both the conveyor line and the vibration sorting device; the vision guidance units 30 are used to guide the robotic gripper in clamping and installing fasteners. The robotic gripper includes a robotic arm 21 and a five-star gripper assembly 22 disposed at the end of the robotic arm 21. The robotic arm 21 is preferably a multi-axis robotic arm capable of performing multiple degrees of freedom of motion. The five-star gripper assembly 22 is used to grip or release fasteners. Guided by a vision guidance unit 30, the robotic gripper can grip fasteners from a vibration sorting device and install them into pre-set mounting holes on the engine housing. By combining the vibration sorting device with the vision guidance unit, fasteners of different specifications and lengths can be quickly identified and separated. The five-star gripper assembly, with its radially arranged grippers, can simultaneously grip multiple fasteners and accurately locate the mounting holes on the engine housing under visual guidance, shortening installation time and improving installation efficiency.

[0021] Preferred, such as Figure 2 As shown, the five-star gripper assembly 22 includes a five-star chuck 221 and gripper assemblies 222 disposed on the five-star chuck 221. The five-star chuck 221 includes a central portion 2211 and gripper mounting portions 2212 arranged radially around the central portion 2211. The central portion 2211 is connected to the end of the robot arm 21. Preferably, there are five gripper mounting portions 2212, distributed at equal angles, and each gripper mounting portion 2212 has a gripper assembly 222 at its end. When clamping fasteners, multiple fasteners can be clamped at once to improve the installation efficiency of fasteners.

[0022] like Figure 3 and 4As shown, the gripper assembly 222 includes a gripper drive unit 2221 and grippers disposed opposite to each other at the execution end of the gripper drive unit 2221; preferably, the gripper drive unit 2221 is a gripper cylinder, and the grippers are disposed at the end of its execution end. The two grippers enclose to form a clamping space for the fastener; the gripper drive unit 2221 can drive the grippers to open and close, realizing the clamping and releasing of the fastener.

[0023] Preferably, the gripper includes a mounting and fixing portion 2222, a connecting portion 2223, and a clamping portion 2224 connected in sequence. Both the mounting and fixing portion 2222 and the clamping portion 2224 extend along a first direction, while the connecting portion 2223 extends along a second direction, forming a bent gripper shape. The end of the clamping portion 2224 tapers inward to more securely clamp the fastener. To facilitate installation with the gripper drive unit 2221, a mounting groove 2225 is formed on the outer side of the mounting and fixing portion 2222. The actuating end of the gripper drive unit 2221 can be installed in the mounting groove 2225. A through mounting hole is also formed on the mounting and fixing portion 2222 to secure it to the gripper drive unit 2221 using fasteners. A clamping groove 2226 is formed on the inner side of the clamping portion 2224; preferably, the clamping groove 2226 is an arc-shaped groove.

[0024] like Figure 5 As shown, the vibration sorting device includes a mounting platform 11 and multiple sets of fastener sorting components 12 disposed on the mounting platform 11. The multiple sets of fastener sorting components 12 can sort fasteners of the same or different specifications. For example, the fastener sorting component 12 includes a fastener storage component 121 and a fastener orientation adjustment component 122. The fastener storage component 121 is disposed on one side of the fastener orientation adjustment component 122 and is used to store fasteners, and can cause the stored fasteners to fall into the fastener orientation adjustment component 122 by vibration. The fastener storage component 121 includes a vibration unit 1211 and a storage box 1212 disposed on the vibration unit 1211. One end of the storage box 1212 extends above the sorting disk 1221, and the storage box 1212 includes a baffle 1213. The baffle 1213 is disposed near the sorting disk 1221 in a way that allows it to be pulled up and down.

[0025] The fastener orientation adjustment assembly 122 is used to adjust the position and orientation of fasteners through vibration, so as to facilitate clamping by the five-star gripper assembly 22. The fastener orientation adjustment assembly 122 includes a vibration unit 1211 and a sorting disk 1221 disposed on the vibration unit 1211. When fasteners are poured into the storage box 1212 and the baffle 1213 is pulled up, the fasteners in the storage box 1212 can fall into the sorting disk 1221 under the vibration of the vibration unit 1211. The fasteners falling into the sorting disk 1221 are positioned and oriented in a manner conducive to clamping under the action of the vibration unit 1211, such as preventing fasteners from overlapping.

[0026] Between the fasteners held by the gripper assembly 222, the vision guidance unit 30 located above the vibration sorting device takes pictures to identify the positions of the fasteners that are easy to grip. The robot arm 21 drives the five-star gripper assembly 22 to move above the vibration sorting device. The robot arm 21 drives the gripper to move to a position that is easy to grip the fastener. The gripper drive unit 2221 drives the gripper to retract and grip the fastener. After that, the robot arm 21 drives the five-star gripper assembly 22 to rotate and use other grippers to grip the fastener. When all grippers have gripped the fastener or the number of gripped fasteners reaches the requirement, the robot arm 21 drives the five-star gripper assembly 22 to move above the conveyor line. Under the guidance of the vision guidance unit 30 located above the conveyor line, the robot arm 21 drives the five-star gripper assembly 22 to install the gripped fasteners sequentially into the preset mounting holes.
