[0074] Example

[0075] This embodiment provides a robot tool quick-connect connector device, such as Figure 1 As shown, including:

[0076] Bracket 1, tool connector 2 and manipulator end connector 3;

[0077] The bracket 1 is a frame structure, including a top plate 11, a bottom plate 12 and a side plate 13 connecting the top plate 11 and the bottom plate 12. The top plate 11 is provided with a semicircular first mounting hole 111. The top plate 11 is also provided with a first positioning component 14 and two second positioning components 15 located next to the first mounting hole 111. The first positioning component 14 and the second positioning component 15 include a first positioning block 141 and a second positioning block 151, and a first fixing bead 142 and a second fixing bead 152 respectively arranged on the first positioning block 141 and the second positioning block 151. The first fixing bead 142 and the second fixing bead 152 are respectively fixed by elastic members and protrude from the first positioning block 141 and the second positioning block 151. Figure 4 As shown, the first positioning block 141 has an installation cavity, and a spring 143 is arranged in the installation cavity. The spring 143 abuts against the fixing bead. The structure of the second positioning component 15 is similar to that of the first positioning component 14. The fixing bead can be partially retracted to exert a certain clamping force. The diameter portion of the first mounting hole 111 is open and located at the edge opening of the top plate 11, so that the tool connector 2 can be installed from the side.

[0078] The tool connector 2 is cylindrical and is clamped in the semicircular second mounting hole 211. It includes a columnar body 21 with an open top. A mounting through hole 26 (usually a screw hole) connected to the tool is provided at the bottom of the body 21. A positioning pin 24 is provided on the inner surface of the bottom of the body 21. A PIN needle 25 is provided in the body 21 to realize power supply to the tool (the power supply method is that the external wire connects the quick-connect connector at the robot arm end to the power supply PIN needle 25 on the tool. If the tool end does not need to be powered, the PIN needle 25 does not need to be provided. It should be noted that the power supply of the PIN needle 25 here does not provide electricity or power for the action of the quick-connect connector itself. The PIN needle 25 is set on a PCB board, and a connector for connecting to the tool is provided at the bottom of the tool connector 2). Two oppositely arranged long strip connecting grooves 22 are provided on the side wall of the body 21, and a first inclined surface 221 is provided above the connecting groove 22. A fixing through hole 23 cooperating with the second fixing bead 152 is provided on the side wall of the body 21.

[0079] The manipulator end connector 3 includes an outer shell 31 that can be inserted into the body 21, and a mounting block 36 fixed in the outer shell 31. A positioning column 35 and a connecting stud 34 are arranged on the top of the outer shell 31. A quick-connect linkage component is arranged in the outer shell 31. The quick-connect linkage component includes a rotating block 321 arranged on the mounting block 36 through a rotating shaft, two clamping blocks 32 that can protrude from the side opening of the outer shell 31, a connecting rod 322 connecting the rotating block 321 and the clamping block 32, and a straight rod 324 connecting the two clamping blocks 32, which is sleeved on the straight rod 3 The elastic member 325 on 24 is restricted by the straight rod 324, and the two blocks 32 can only move along the straight rod 324. When one or both of the blocks 32 are subjected to an axial external force (a force or a component of a force along the straight rod 324), the block 32 can retract into the side opening of the outer shell 31. It should be noted here that the rotating block 321 and the connecting rod 322 in the quick-connect linkage component ensure that one block 32 moves and the other block 32 can be linked. The elastic member 325 enables the block 32 to rebound to the initial position without the action of an external force.

[0080] The bottom of the outer shell 31 has a positioning hole 311 that cooperates with the positioning pin 24, and a third mounting hole 312 that is coaxially arranged with the mounting through hole 26 (that is, the mounting column on the tool can extend into the mounting through hole 26 and the third mounting hole 312). The bottom of the block 32 is a second inclined surface 323 to facilitate cooperation with the first inclined surface 221. The first inclined surface 221 and the second inclined surface 323 together play a guiding role, making it easier for the block 32 to enter the connecting groove.

[0081] A PIN pin interface 313 that cooperates with the PIN pin 25 is also provided at the bottom of the manipulator end connector 3 .

[0082] A groove 27 is provided on the side wall of the body 21 to form a certain space for the power supply line of the manipulator end connector 3 to pass through.

[0083] Furthermore, the second positioning blocks 151 are arranged opposite to each other, and the first positioning block 141 and the two second positioning blocks 151 are arranged in an isosceles triangle. The first positioning block 141 is arranged opposite to the side opening of the semicircular first mounting hole 111 .

[0084] It is worth noting that the tool-end quick-connect connector device of this embodiment is arranged in a row when in use, and a tool is connected to the bottom of the tool connector 2 and the inside of the bracket 1 (each device is connected to a different device). After the quick-connect connector connection end of the robotic arm is matched with the tool connector 2, the robotic arm drives the tool connector 2 and the tool to move out from the side of the semicircular first mounting hole 111 to separate the tool connector 2 from the bracket 1, and then the corresponding tool can be used. After the tool is used, the tool connector 2 is placed back in the bracket 1, and the robotic arm drives the tool connector 2 to separate from the tool connector 2, and the robotic arm drives the tool connector 2 to connect to the new tool connector 2. The connection between the tool connector 2 driven by the robot arm and the tool connector 2 is achieved by extending the card block 32 into the connecting groove 22. When the tool connector 2 is still on the bracket 1, the first fixing bead 142 abuts against the card block 32, causing the card block 32 to retract. When the tool connector 2 is separated from the bracket 1, the first fixing bead 142 loses its abutment against the card block 32, and the card block 32 is completely extended into the connecting groove 22 to fix the tool connector 2 and the connecting end of the quick-connect joint at the robot arm end.

[0085] The first fixing bead 142 may be a protrusion with a spherical front end. The first positioning assembly 14 and the second positioning assembly 15 are fixed to the top of the bracket 1 by screws for easy installation.

[0086] If the tool does not need to be powered but needs to be ventilated, such as if the tool end contains a cylinder, electrical components such as PIN needles can be replaced with air circuit interfaces.

[0087] The robot tool quick-connect connector device of this embodiment has a separate design of the bracket 1, the tool connector 2 and the manipulator end connector 3. Different tools can be pre-installed on the bottom of the tool connector 2. The manipulator end connector 3 is connected to the manipulator. A semicircular mounting hole is provided on the bracket 1. The diameter portion of the mounting hole is an opening and is located at the edge opening of the top plate. The tool connector 2 can be easily loaded into the bracket or removed from the bracket from the edge opening. And the triangle fixation of a positioning component and two second positioning components is used to make the connection between the tool connector and the bracket more stable. At the same time, as a universal component, the tool connector 2 can be connected to different tools through its bottom, which can facilitate the standardization of the joint. The manipulator with the manipulator end connector 3 can directly cooperate with the tool connector 2 equipped with different tools to achieve the switching of different tools.

[0088] A wire protector 33 (a spring through which the wire passes) is also provided on one side of the outer shell 31 , and the wire is connected to the PIN needle interface 313 .

[0089] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
