For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Such as Figure 1-2The robot tool quick-change device for stamping working conditions shown in the figure includes an upper connection plate 1 and a lower connection plate 2 that are respectively detachably fixed to the robotic arm and the end effector by bolts, so that the detachable connection between the robotic arm and the end effector is realized through the snap connection between the upper connection plate 1 and the lower connection plate 2, and then the end effector is controlled to work by the robotic arm. A locking assembly is detachably fixed to the upper connection plate 1 by bolts, and a locking ring plate 21 is detachably fixed to the lower connection plate 2 by bolts, forming a structure in which the locking assembly is inserted into the locking ring plate 21 and locked, realizing the locking connection between the upper connection plate 1 and the lower connection plate 2, so that the locking assembly and the locking ring plate 21 are respectively connected to the upper connection plate 1 and the lower connection plate 2 to form a whole. Furthermore, by inserting the locking assembly into the locking ring plate 21, the locking assembly is snap-locked with the locking ring plate 21, realizing the snap-locking connection between the upper connection plate 1 and the lower connection plate 2.

[0020] As Figure 1-2The robot tool quick-change device for stamping working conditions shown in the figure, the locking assembly includes a locking head 5, a piston disk 4, a locking cam 4A and locking balls 7. An upper fixing groove 3 is formed on the upper connecting disk 1. The vertical section of the locking head 5 is T-shaped. The locking head 5 is partially inserted into the fixing groove and is detachably fixed in the upper fixing groove 3 by bolts, so that the locking head 5 is limited by the upper fixing groove 3 to prevent the locking head 5 from moving relative to the upper connecting disk 1, thereby realizing the stable and firm connection between the locking head 5 and the upper connecting disk 1. A first clamping ring groove is formed on the end face of the locking head 5 in the upper fixing groove 3, and a first sealing ring is clamped and fixed in the first clamping ring groove, which is convenient for clamping and limiting the first sealing ring through the first clamping ring groove to prevent the first sealing ring from detaching from the locking head 5. Then, the gap between the locking head 5 and the upper fixing groove 3 is sealed by the first sealing ring to prevent air leakage from the gap between the locking head 5 and the upper fixing groove 3 in the air cylinder 3A, which affects the sliding of the piston disk 4 in the air cylinder 3A. An air cylinder 3A is formed in the upper fixing groove 3, and the piston disk 4 is movably connected in the air cylinder 3A, which is convenient for the piston disk 4 to slide in the air cylinder 3A, and then drives other components connected to the piston disk 4 to move simultaneously. A second clamping ring groove is formed on the side end face of the piston disk 4, and a second sealing ring is clamped in the second clamping ring groove, which is convenient for clamping and limiting the second sealing ring through the second clamping ring groove to prevent the second sealing ring from detaching from the side end face of the piston disk 4. Then, the gap between the piston disk 4 and the air cylinder 3A is sealed by the second sealing ring, so that the piston disk 4 divides the air cylinder 3A into two independent air chambers. Then, by inflating the two air chambers respectively, the piston disk 4 slides in the air cylinder 3A. Upper air inlets 8 and lower air inlets 9 communicating with the upper and lower ends of the air cylinder 3A are formed on the outer side wall of the upper connecting disk 1, so that the two independent air chambers divided by the piston disk 4 in the air cylinder 3A are inflated through the upper air inlets 8 and the lower air inlets 9 respectively, and the piston disk 4 moves in the air cylinder 3A. A telescopic groove 6 is formed at one end of the locking head 5 away from the air cylinder 3A. The vertical section of the piston disk 4 is T-shaped. The piston disk 4 partially penetrates through the locking head 5 and extends into the telescopic groove 6, so that the part of the piston disk 4 in the telescopic groove moves simultaneously by the sliding of the piston disk 4 in the air cylinder 3A. A third clamping ring groove is formed on the inner side wall of the locking head 5 at the position where the piston disk 4 penetrates through the locking head 5, and a third sealing ring is clamped and fixed in the third clamping ring groove, which is convenient for clamping and limiting the third sealing ring through the third clamping ring groove to prevent the third sealing ring from detaching from the locking head 5. At the same time, the gap between the piston disk 4 and the locking head 5 is sealed by the third sealing ring to prevent air leakage from the gap between the piston disk 4 and the locking head 5, which affects the sliding of the piston disk 4 in the air cylinder 3A. The piston disk 4 and the locking cam 4A are detachably and fixedly connected by a connecting bolt in the telescopic groove 6, so that the locking cam 4A is connected to one end of the piston disk 4, and then the simultaneous movement is realized.The end face of the piston disk 4 close to the locking cam 4A is provided with a fourth clamping ring groove, and a fourth sealing ring is clamped and fixed in the fourth clamping ring groove, which is convenient for clamping and limiting the fourth sealing ring through the fourth clamping ring groove, avoiding the detachment of the fourth sealing ring from the piston disk 4. At the same time, the fourth sealing ring is used to block the gap between the piston disk 4 and the locking projection, preventing air leakage from the gap between the piston disk 4 and the locking projection and affecting the sliding of the piston disk 4 in the cylinder 3A.

[0021] As Figure 1-2 shown in the robot tool quick-change device for stamping working conditions, a plurality of expansion holes 6A are provided on the inner side wall of the expansion groove 6, and the locking balls 7 are movably arranged in the expansion holes 6A, forming a structure in which the movement of the locking cam 4A in the expansion groove 6 drives the locking balls 7 to move in the expansion holes 6A. When the locking cam 4A moves away from the cylinder 3A under the drive of the piston disk 4, the locking balls 7 are pressed to move in the expansion holes 6A until the locking balls 7 partially protrude from the expansion holes 6A when the locking cam 4A stops moving, thereby realizing the clamping and locking with the locking ring plate 21; when the locking cam 4A moves towards the cylinder 3A under the drive of the piston disk 4, the pressure of the locking cam 4A on the locking balls 7 is released, enabling the locking balls 7 to retract into the expansion holes 6A under the action of other external forces and releasing the clamping state with the locking ring plate 21. The diameter of the expansion holes 6A on the outer end face is smaller than the diameter of the locking balls 7, preventing the locking balls 7 from detaching from the outer end face of the expansion holes 6A and affecting the subsequent clamping and locking of the locking assembly with the locking ring plate 21. The outer end face of the locking cam 4A away from the piston disk 4 is a multi-segment inclined surface, and the inclination angle increases from top to bottom, so that when the locking cam 4A moves away from the cylinder 3A, the lowermost inclined surface first contacts the locking balls 7. As the locking cam 4A continues to move, the inclined surface gradually presses the locking balls 7 to move into the expansion holes 6A until the last inclined surface presses the locking balls 7, causing the locking balls 7 to move to the farthest moving distance in the expansion holes 6A. At this time, the locking balls 7 partially protrude from the outer end face of the expansion holes 6A, and at the same time, the inclined surface is used to limit the locking balls 7 to prevent them from detaching from the expansion holes 6A. One end of the locking cam 4A away from the piston disk 4 is located below the uppermost end of the limiting hole 23, and the distance between the outer end face of the end of the locking cam 4A away from the piston disk 4 and the limiting hole 23 is smaller than the diameter of the locking balls 7, so that after the locking cam 4A moves towards the cylinder 3A, it is prevented that the locking balls 7 detach from the inner end face opening of the expansion holes 6A and affect the subsequent clamping and locking of the locking assembly with the locking ring plate 21.

[0022] As Figure 1-2The robot tool quick-change device for stamping working conditions shown in the figure. A lower fixing groove 20 is formed on the lower connecting plate 2. The locking ring plate 21 is detachably fixed in the lower fixing groove 20 through bolts, so that the locking ring plate 21 is limited by the lower fixing groove 20 to prevent the locking ring plate 21 from moving relative to the upper connecting plate 1, thereby realizing the stable and firm connection between the locking ring plate 21 and the upper connecting plate 1. A locking ring groove 22 is formed on the inner end face of the locking ring plate 21. After the locking head 5 is inserted into the locking ring plate 21, the locking cam 4A presses the locking ball 7 to partially protrude from the limiting hole 23 and is clamped in the locking ring groove 22, so that the part of the locking ball 7 protruding from the telescopic hole 6A moves into the locking ring groove 22, realizing the clamping and locking between the locking assembly and the clamping ring plate, and further realizing the clamping and locking between the upper connecting plate 1 and the lower connecting plate 2. The end face of the locking ring groove 22 close to the upper connecting plate 1 is an inclined end face, so that after the locking cam 4A moves in the direction close to the cylinder 3A, the inclined end face arranged obliquely can press the locking ball 7 to retract into the telescopic hole 6A, so that the locking assembly is disengaged from the clamping and locking state with the locking ring plate 21, and further realizing the convenient separation of the upper connecting plate 1 and the lower connecting plate 2.

[0023] As Figure 1-2 For the robot tool quick-change device for stamping working conditions shown in the figure, a limiting post 15 is detachably fixed on the upper connecting plate 1 through bolts. A limiting hole 23 is formed on the lower connecting plate 2, and there are at least two limiting posts 15 and limiting holes 23, constituting a structure for positioning when the upper connecting plate 1 and the lower connecting plate 2 are connected by inserting the limiting post 15 into the limiting hole 23. It is convenient to limit the docking of the upper connecting plate 1 and the lower connecting plate 2 by inserting the limiting post 15 into the limiting hole 23, so that the upper connecting plate 1 and the lower connecting plate 2 can be accurately docked to avoid misalignment and affect the connection between the upper connecting plate 1 and the lower connecting plate 2. Identifiers are provided on the outer end faces of the upper connecting plate 1 and the lower connecting plate 2 to facilitate the accurate docking when the upper connecting plate 1 and the lower connecting plate 2 are connected, avoid misalignment, and prevent damage to other components loaded on the upper connecting plate 1 and the lower connecting plate 2 when the upper connecting plate 1 and the lower connecting plate 2 are locked and connected. A plurality of upper fixing holes are formed on the outer end face of the upper connecting plate 1, and a plurality of lower fixing holes are formed on the outer end face of the lower connecting plate 2, so that the upper connecting plate 1 and the lower connecting plate 2 can be respectively fixed on the robot and the end effector through the upper fixing holes and the lower fixing holes, and at the same time, electrical modules are loaded on the side end faces of the upper connecting plate 1 and the lower connecting plate 2 by using the upper fixing holes and the lower fixing holes.

[0024] As Figure 1-2The robot tool quick-change device for stamping working conditions shown in the figure has a number of upper loading grooves and lower loading grooves respectively formed on the edges of the upper connecting disc 1 and the lower connecting disc 2, which facilitates loading and installing electrical modules on the upper connecting disc 1 and the lower connecting disc 2 through the upper loading grooves and the lower loading grooves. Furthermore, through the electrical modules, the robotic arm and the end effector can work better. At the same time, the upper loading grooves and the lower loading grooves are used to limit the loaded electrical modules, preventing the electrical modules from moving randomly on the upper connecting disc 1 and the lower connecting disc 2, and increasing the connection stability between the electrical modules and the upper connecting disc 1 and the lower connecting disc 2. Upper connecting screw holes and lower connecting screw holes are respectively formed in the upper loading grooves and the lower loading grooves, which facilitates screwing the loaded electrical modules to the upper connecting disc 1 and the lower connecting disc 2 through the upper connecting screw holes and the lower connecting screw holes. Upper reinforcing screw holes and lower reinforcing screw holes corresponding to the upper loading grooves and the lower loading grooves are respectively formed on the side end faces of the upper connecting disc 1 and the lower connecting disc 2, enabling the electrical modules to be more stably and firmly connected to the upper connecting disc 1 and the lower connecting disc 2 respectively through the upper reinforcing screw holes and the lower reinforcing screw holes. At the same time, the flexibility of the connection between the electrical modules and the upper connecting disc 1 and the lower connecting disc 2 is increased. The upper air inlet 8 and the lower air inlet 9 are formed on the side end face of the upper connecting disc 1 between two adjacent upper loading grooves, so that the upper air inlet 8 and the lower air inlet 9 do not occupy more loading space of the upper connecting disc 1 and prevent affecting the connection between the upper connecting disc 1 and the electrical module.

[0025] As Figure 1-2The robot tool quick-change device for stamping working conditions shown has an upper negative-pressure air hole group including a first upper negative-pressure air hole 16 and a plurality of second upper negative-pressure air holes 18, and a lower negative-pressure air hole group including a first lower negative-pressure air hole 25 and a plurality of second lower negative-pressure air holes 27. The diameter of the first upper negative-pressure air hole 16 is smaller than that of the second upper negative-pressure air hole 18, and the diameter of the first lower negative-pressure air hole 25 is smaller than that of the second lower negative-pressure air hole 27, which facilitates the realization of the negative-pressure connection between the air source and the end effector through the upper negative-pressure air hole group and the lower negative-pressure air hole group, and then controls the suction cup to position the workpiece. Moreover, through the large-diameter second upper negative-pressure air hole 18 and second lower negative-pressure air hole 27, it is ensured that a large flow of negative pressure can pass through, and thus sufficient negative-pressure suction force is guaranteed for the suction cup on the end effector. A plurality of first sealing connectors 17 and second sealing connectors 19 that connect the first upper negative-pressure air hole 16 and the plurality of second upper negative-pressure air holes 18 are fixedly clamped on the end face of the upper connecting plate 1 close to the lower connecting plate 2. The first sealing connectors 17 and second sealing connectors 19 are made of rubber. A plurality of first connecting grooves and second connecting grooves that connect the first sealing connectors 17 and second sealing connectors 19 are formed on the end face of the lower connecting plate 2 close to the upper connecting plate 1. After the upper connecting plate 1 and the lower connecting plate 2 are connected, the first sealing connectors and the second sealing connectors 19 are respectively inserted into the first connecting grooves and second connecting grooves, realizing a structure in which the upper negative-pressure air hole group and the lower negative-pressure air hole group are hermetically connected. When the upper connecting plate 1 and the lower connecting plate 2 are locked and connected, the first sealing connectors 17 and second sealing connectors 19 are respectively inserted into the first connecting grooves and second connecting grooves, realizing the hermetic connection between the first upper negative-pressure air hole 16 and the first lower negative-pressure air hole 25, and between the second upper negative-pressure air hole 18 and the second lower negative-pressure air hole 27.

[0026] As Figure 1-2The robot tool quick-change device for stamping working conditions shown in the figure. An installation groove 10 is formed on the side end face of the upper connecting plate 1. An upper proximity sensor 11 and a lower proximity sensor 12 are detachably fixed in the installation groove 10 by bolts. An upper communication hole 13 and a lower communication hole 14 communicating with the cylinder 3A are formed in the installation groove 10. The upper proximity sensor 11 and the lower proximity sensor 12 partially extend into the upper communication hole 13 and the lower communication hole 14 respectively, so as to monitor the movement of the piston disk 4 in the cylinder 3A through the upper proximity sensor 11 and the lower proximity sensor 12. Furthermore, signals are transmitted to the control module through the upper proximity sensor 11 and the lower proximity sensor 12, and the control module controls whether air is pumped into the upper air inlet hole 8 and the lower air inlet hole 9. Sealing gaskets are arranged at the gaps between the upper proximity sensor 11 and the lower proximity sensor 12 and the installation groove 10, which is convenient for blocking the gaps between the upper proximity sensor 11 and the lower proximity sensor 12 and the installation groove 10 through the sealing gaskets, and avoiding the leakage of gas in the cylinder 3A from the communication holes, which affects the sliding of the piston in the cylinder 3A. A transmitter of a magnetic proximity sensor is fixedly embedded on the piston disk 4. A pair of receivers of the magnetic proximity sensor are detachably fixed on the outer side end face of the upper connecting plate 1 by bolts, so as to receive the signals emitted by the transmitter of the magnetic proximity sensor on the piston disk 4 through the receivers of the magnetic proximity sensor, and further detect the movement of the piston disk 4 in the cylinder 3A, and the control module controls whether air is pumped into the upper air inlet hole 8 and the lower air inlet hole 9.
