Description

Technical Field

[0001] This utility model belongs to the field of quick tool replacement for robotic arms, specifically relating to an octagonal tube quick-change connection device. Background Technology

[0002] With the widespread adoption of Industry 4.0, octagonal tube grippers are now widely used in various processes on intelligent production lines for automobile manufacturing, such as gluing, welding, and handling. However, in order to meet market demands and enhance market competitiveness, automakers are constantly launching new models, which requires different octagonal tube grippers.

[0003] Traditional octagonal tube grippers consist of a frame and units. The frame holds the unit components, while the units contain clamping cylinders and other parts for clamping and securing vehicle body components. However, current octagonal tube gripper designs are generally only designed for specific parts of a particular vehicle model, making them unsuitable for other parts of the vehicle or other vehicle models. For example, a gripper designed for the door hood of vehicle model A can only grip the door hood of model A, not the hood of model A, nor the door hood of model B. If these other grippers are required, the entire gripper system needs to be redesigned and replaced. This forces automakers to redesign or modify the entire gripper system when launching new models, resulting in wasted resources, high costs, and lengthy development cycles.

[0004] Therefore, there is an urgent need to develop an octagonal tube quick-change connection device to solve the above problems. Utility Model Content

[0030] Example

[0031] An octagonal tube quick-connect device, such as Figure 1-5 As shown, it includes:

[0032] The gun changing disc mother plate 1 is fixed to the lower end of the octagonal tube 4. The gun changing disc mother plate 1 is provided with an octagonal tube 4 connecting surface 15. The octagonal tube 4 connecting surface 15 is provided with a screw hole and is connected to the octagonal tube 4 by bolts.

[0033] Multiple gun changing discs 2, with different clamping units 5 installed at the bottom to adapt to different vehicle models or parts; the gun changing discs 2 are detachably connected to the bottom of the gun changing disc mother disc 1;

[0034] The sub-panel parking area 6 is used to store the gun-changing pans 2 equipped with different clamping units 5. Centralized management of multiple types of clamping units 5 allows for automatic switching by the robot as needed.

[0035] By fixing the gun changing disc mother plate 1 to the frame of the octagonal tube 4, which is connected to the robot; different clamping units 5 are installed on the gun changing disc plate 2; the gun changing disc mother plate 1 and the gun changing disc plate 2 are detachably connected, so that the clamping units 5 can be quickly replaced to adapt to different vehicle models or parts, without having to replace the entire gripper, which significantly reduces costs and time.

[0036] The shape of the connecting surface 15 of the octagonal tube 4 matches the outer contour of the octagonal tube 4. This is used to improve connection stability and positioning accuracy, avoid installation deviations, and ensure precise alignment between the clamping unit 5 and the vehicle body parts.

[0037] In a preferred embodiment, the interface surface of the gun changing disc mother plate 1 is provided with four air holes 13, divided into a first group of air holes 13 and a second group of air holes 13, each group containing two air holes 13. Each air hole 13 is provided with an air pipe quick connector 3 corresponding to the side position of the gun changing disc mother plate 1. The interface surface of the gun changing disc 2 is provided with four docking air holes 23, divided into a first group of docking air holes 23 and a second group of docking air holes 23, each group containing two docking air holes 23. Each docking air hole 23 is provided with an air pipe quick connector 3 corresponding to the side position of the gun changing disc 2. The first group of air holes 13 and the first group of docking air holes 23 are connected to form a first air passage, and the second group of air holes 13 and the second group of docking air holes 23 are connected to form a second air passage. The first air passage is used for clamping by the clamping cylinder of the clamping unit 5, and the second air passage is used for releasing by the clamping cylinder of the clamping unit 5. The quick-connector 3 is used to connect the air pipe. The air hole 13 of the gun changing plate 1 is connected to the valve island through the air pipe. The docking air hole 23 of the gun changing plate 2 is connected to the clamping cylinder of the clamping unit 5 through the air pipe. The valve island drives the clamping cylinder to perform clamping and releasing actions through the first air passage and the second air passage respectively.

[0038] In a preferred embodiment, the interface surface of the weapon changing disc mother disc 1 is provided with guide pins 12, and the interface surface of the weapon changing disc 2 is provided with matching guide holes 22. There are two guide pins 12, symmetrically distributed on the interface surface of the weapon changing disc mother disc 1. These are used to quickly and accurately locate the docking position between the weapon changing disc mother disc 1 and the weapon changing disc 2, reducing manual adjustment time and improving switching efficiency.

[0039] In a preferred embodiment, the bottom of the gun changing plate 2 is provided with a screw hole, which is connected to the clamping unit 5 by bolts.

[0040] In a preferred embodiment, a mother plate electrical control module 11 is provided on one side of the gun changing disc mother plate 1, and a daughter plate electrical control module is provided at a corresponding position on the gun changing disc 2, which is coupled to the mother plate electrical control module 11 via a pin connector. A cylinder sensor is installed on the clamping cylinder of the clamping unit 5 to monitor the clamping or releasing state of the cylinder in real time. The cylinder sensor is signal-connected to the gun changing disc 2 electrical control module, which transmits status signals to the gun changing disc mother plate 1 electrical control module via a pin connector. The gun changing disc mother plate 1 electrical control module communicates with the PLC control system via an industrial bus. When the gun changing disc mother plate 1 is disengaged from the gun changing disc 2, the pin connector is simultaneously disconnected, and the electrical connection between the gun changing disc 2 electrical control module and the gun changing disc mother plate 1 electrical control interface is terminated. This achieves real-time monitoring of the clamping state and automated control via the PLC system, reducing manual intervention.

[0041] The gun-changing disc 1 has an L-shaped air hole 16 (for locking) and a U-shaped air hole 17 (for releasing) on ​​one side, which are connected to a valve island via air pipes. The valve island controls the air intake and exhaust. When locking, the valve island supplies air to the L-shaped hole, pushing the internal mechanism 14 to lock; when releasing, the valve island supplies air to the U-shaped hole, releasing the locked state, thereby achieving the locking and releasing functions with the gun-changing disc 2. Its working principle is the same as that of gun-changing discs in the prior art.

[0042] like Figure 6 As shown, the working process of this embodiment is as follows:

[0043] First, the gun-changing disc mother plate 1 is fixed to a designated position on the octagonal tube 4 with bolts, and its connecting surface 15 precisely matches the outer contour of the octagonal tube 4. When the production line needs to switch models or parts, the robot carries the gun-changing disc mother plate 1 to the daughter plate parking area 6, and aligns and positions it with the guide pin 12 of the gun-changing disc mother plate 1 and the guide hole 22 of the gun-changing disc plate 2. Through air circuit control, the valve island supplies air to the L-hole, pushing the internal mechanism 14 to lock, thus locking the gun-changing disc mother plate 1 and the gun-changing disc plate 2. At the same time, the valve island supplies air, driving the clamping cylinder to perform clamping and releasing actions through the first air circuit and the second air circuit respectively. The electronic control modules of the gun-changing disc mother plate 1 and the gun-changing disc plate 2 complete signal interaction through the pin connector, monitor the cylinder status of the clamping unit 5 in real time and feed it back to the PLC system. After completing the current task, the robot returns the gun-changing plate 2 to the parking bay and quickly selects the next suitable gun-changing plate 2. The entire process requires no human intervention, enabling production across multiple vehicle models and workstations. This eliminates the need to replace the entire octagonal tube 4 gripper.
