[0001] The present invention relates to the technical field of quick-change discs, in particular to an automatically assembled and disassembled quick-change disc with stable connection. Background Art

[0002] With the development of science and technology, the efficiency of industrial production has been increasingly valued. Production efficiency plays a great role in profitability. Industrial robots are widely used and can effectively replace manual labor, improve work efficiency and reduce costs. However, existing industrial robots require manual replacement of different types of operating tools to adapt to the handling and processing of different types of objects.

[0003] Authorization announcement number CN217362023U discloses a ball-type electric quick-change connector. The connector comprises a first connecting portion with a groove and a second connecting portion. The first connecting portion comprises a main body, a motor disposed therein, a linkage assembly, a tapered piston, and a plurality of balls. The main body comprises a protrusion that fits within the groove. The tapered piston is movably disposed within the protrusion and tightly connected to the inner wall of the protrusion. The motor drives the tapered piston via the linkage assembly. The sidewall of the protrusion has a plurality of through-holes, and the balls are movably disposed in the through-holes in a one-to-one correspondence. This invention provides a ball-type electric quick-change connector that addresses the problem of the prior art, which suffers from a complicated connector structure and inability to achieve quick changes.

[0004] Authorization announcement number CN218313578U discloses an electric quick-change clamp. This utility model uses an electric push rod to drive a pressing sleeve to act on a steel ball, which is then used to achieve a snap-on connection with the tool end assembly. A positioning pin is inserted into the tool end assembly to secure the assembly. This allows for quick clamping without the need for rotation, resulting in simple and easy operation. The communication line connector uses a multi-core probe connector, making power and communication wiring simple and reliable. The entire device is simple in structure, easy to operate, and features a stable structural connection, making it highly safe to use.

[0005] Authorization announcement number CN221985149U discloses an automatic quick-disc changer with dual detection and feedback, featuring a stable connection at the end of a robot. The device comprises a disc change assembly, comprising a main disc housing, a guide sleeve, a guide hole, a locking steel ball, a piston, a secondary disc inner core, a limit groove, a secondary disc housing, a first mounting hole, a proximity sensor, a second mounting hole, and a magnetic sensor. The guide sleeve is fixedly connected to the front of the inner side wall of the main disc housing. The utility model detects whether the piston is extended or retracted by a magnetic sensor, and simultaneously detects whether the secondary disc is fitted by a proximity sensor. The dual detection and feedback signals from the magnetic and proximity sensors are used to monitor whether the clamping action is complete. The dual detection and feedback mechanism of the magnetic and proximity sensors enables reliable monitoring of the locking and fitting process of the stable connection automatic quick-disc changer, preventing the tool from falling off, shifting, or failing to perform its task correctly, thereby improving the robot's safe and stable operation performance and production efficiency.

[0006] As mentioned above, the connection between existing robots and tools usually adopts a stable connection automatic assembly and disassembly quick-change plate structure. The stable connection automatic assembly and disassembly quick-change plate adopts an electric or pneumatic structure to achieve the action of the stable connection automatic assembly and disassembly quick-change plate. However, when the robot is in a mobile state, there may be power outages or inconveniences in connecting the air source.

[0056] When the locking post 234 is inserted into the locking sleeve 25, the locking cylinder 26 is locked, causing the locking ball 252 to disengage from the receiving groove 261. Under the squeezing action of the inner wall of the locking cylinder 26, the locking ball 252 is driven into the locking groove 235, thereby achieving relative fixation between the locking post 234 and the locking sleeve 25. When the locking cylinder 26 continues to rotate, the receiving groove 261 corresponds to the position of the locking ball 252, and the locking ball 252 can enter the receiving groove 261, thereby achieving relative unlocking between the locking post 234 and the locking sleeve 25.

[0072] Referring to Figure 3The connecting seat 11 comprises a connecting ring 111 bolted with the storage beam 1, a support table 112 is arranged on the upper side of the connecting ring 111, and a guide column 113 is arranged on the upper end of the support table 112.

[0073] Working principle: as Figure 7 shown, the quick-change disc assembly 2 is in a state of not being connected with the upper disc 23 and not being connected with the connecting seat 11.

[0074] Before work, the quick-change disc assembly 2 is sleeved on the connecting seat 11, that is, placed on the storage beam 1. During the process of sleeving the quick-change disc assembly 2 on the connecting seat 11, the guide column 113 of the connecting seat 11 guides the connecting seat 11 to enter the protection ring 211 on the lower side of the shell 21, the support table 112 of the connecting seat 11 abuts against the second disc 271, the connecting seat 11 drives the second disc 271 and the lower driving column 27 to move upward until the connecting seat 11 is completely inserted into the protection ring 211, at this time, the slide column 272 is located at the lower end of the first vertical groove 262, at this time, the containing groove 261 of the driving rotating drum 26 is located outside the locking ball 252 of the locking sleeve 25, at this time, the locking ball 252 can be retracted into the containing groove 261, and at this time, the locking column 234 can be normally inserted into the locking sleeve 25.

[0075] When the robot drives the upper disc 23 and the lower disc 22 to be connected, the upper disc 23 is close to the lower disc 22, at this time, the upper disc 23 first contacts and presses the first disc 246, the first disc 246 drives the upper driving column 24 to move downward, the clamping plate 241 at the lower end of the upper driving column 24 drives the locking rotating drum 26 to move downward, at this time, the slide column 272 moves upward in the first vertical groove 262, at this time, the locking rotating drum 26 is in a non-rotating state, at this time, the locking column 234 on the lower side of the upper disc 23 can smoothly enter the locking sleeve 25.

[0076] When the upper disc 23 and the lower disc 22 are in contact, at this time, the clamping plate 241 is driven by the driving ring 212 to retract and separate from the locking rotating drum 26, the locking rotating drum 26 is driven by the second spring 253 to move upward, at this time, the slide column 272 passes through the first short groove 263 and enters the first inclined groove 264, and moves downward along the first inclined groove 264, at this time, the slide column 272 drives the locking rotating drum 26 to rotate, the locking rotating drum 26 presses the locking ball 252 to enter the locking groove 235 of the locking column 234, the relative locking between the locking column 234 and the locking sleeve 25 is realized, that is, the relative locking between the upper disc 23 and the lower disc 22 is realized.

[0077] When the robot drives the quick-change disc assembly 2 out of the connecting base 11, the connecting base 11 no longer compresses the second disc 271. Driven downward by the second spring 253, the lower drive post 27 moves downward, and the slide post 272 moves downward along the second vertical slot 265, ultimately resting at the opposite lower end of the second vertical slot 265. The slide post 272 then locks the locking cylinder 26, which remains stationary. The upper and lower discs 23 and 22 remain locked. The protective ring 211 prevents the second disc 271 from being squeezed and moved during robot operation.

[0078] When the robot finishes its work, it needs to replace the tool, that is, replace the quick-change disc assembly 2. The robot installs the quick-change disc assembly 2 on the connecting seat 11. During this process, the support platform 112 of the connecting seat 11 squeezes the second disc 271, and the second disc 271 drives the lower driving column 27 to move upward. The sliding column 272 moves upward along the second inclined groove 267 and drives the locking cylinder 26 to rotate. The receiving groove 261 of the locking cylinder 26 rotates to the outside of the locking ball 252. At this time, the locking ball 252 can be retracted into the receiving groove 261. At this time, the locking column 234 and the locking sleeve 25 are unlocked, that is, the upper plate 23 and the lower plate 22 are unlocked, and the robot can drive the upper plate 23 away from the lower plate 22.

[0079] As the upper disc 23 moves away from the lower disc 22, the first disc 246 is no longer under pressure from the upper disc 23, and the first spring 242 drives the upper drive column 24 to move upward until the clamping plate 241 moves to the upper side of the locking cylinder 26, completing the reset and preparing for the next connection.
