Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0030] Please see Figures 1-5 The present invention provides a technical solution: a pneumatic-electro-hydraulic floating pod, comprising a main-side pod 1 and a tool-side pod 2, wherein the main-side pod 1 is connected to the main control end that does not need to be replaced, and the tool-side pod 2 is connected to the clamp end.

[0032] The main side connector 1 is provided with a gas path self-sealing port 102 on its docking surface, and a self-sealing structure 4 is provided inside the gas path self-sealing port 102.
[0033] like Figure 3 As shown, in some embodiments, the self-sealing structure 4 includes a fixing rod 401, a force-bearing rod 402, and a spring 403. A limiting hole 1021 is provided at the bottom center of the air passage self-sealing port 102. The fixing rod 401 is installed at the bottom of the air passage self-sealing port 102, and its end extends into the limiting hole 1021.
[0034] A limiting block 4011 is provided above the limiting hole 1021. The limiting block 4011 is fixed on the outer diameter of the fixing rod 401. The diameter of the limiting block 4011 is larger than that of the limiting hole 1021, and it is used to restrict the movement of the fixing rod 401.
[0035] The diameter of the end of the fixing rod 401 away from the limiting hole 1021 gradually increases to form a "cone" shape, and it is engaged with the force rod 402. The force rod 402 is clearance-fitted with the air passage self-sealing port 102. The force rod 402 contacts the bottom of the air passage self-sealing port 102 through the spring 403.

[0036] When the main side connector 1 and the tool side connector 2 are not connected, the sealing material seals the gas port under its own elasticity to prevent gas leakage.
[0037] During the docking process, as the main side connector 1 and the tool side connector 2 approach each other, the sealing structure gradually opens under the action of external pressure, allowing the gas to be transmitted smoothly.
[0038] like Figure 1 and Figure 2 As shown, in some embodiments, a multi-core wire 103 is provided on the adjacent surface of the main side connector 1.

[0040] During docking, the connecting pin 104 is accurately inserted into the connecting hole 204 of the tool-side connector, realizing the mechanical positioning and connection between the main-side connector 1 and the tool-side connector 2, and ensuring the accuracy of the electrical connection and pneumatic connection.

[0043] like Figure 4As shown, in some embodiments, a second air passage self-sealing port 202 is provided on the mating surface of the tool-side air-insertion 2. A countersunk hole 2021 is provided at the second air passage self-sealing port 202. A second fixing rod 206 is rotatably connected to the opening of the countersunk hole 2021. One end of the second fixing rod 206 extends into the countersunk hole 2021 and is sealed to the countersunk hole 2021 by a bearing. The other end is fixed with a second limiting block 2061. The second limiting block 2061 fits against the mating surface of the tool-side air-insertion 2. The second fixing rod 206 is hollow inside and extends into the countersunk hole 2021. The aperture inside 021 gradually increases. A force-bearing rod 207 is provided inside the second fixed rod 206. A limit rod 208 is fixed on the outer diameter of the second force-bearing rod 207. The limit rod 208 is supported on the inner wall of the second fixed rod 206 to limit the movement of the second force-bearing rod 207. The second force-bearing rod 207 and the bottom of the second air passage self-sealing port 202 are connected by a second spring 209. The second spring sleeve 207 is sleeved on the outer diameter of the second force-bearing rod 207. One end of the second spring 209 is fixed on the limit rod 208, and the other end is in contact with the bottom of the second air passage self-sealing port 202.
[0044] When not connected, the second self-sealing port 202 of the gas passage automatically seals to prevent gas leakage; when connected, it opens under external pressure, allowing gas to be transmitted from the main side connector 1 to the pneumatic components of the tool side connector 2.
[0045] Multi-core wire 203 is provided on the adjacent surfaces of the docking surface of the tool-side connector 2. The position of multi-core wire 203 corresponds to that of multi-core wire 103, and the structure of multi-core wire 203 is the same as that of multi-core wire 103. One end of multi-core wire 203 is connected to the tool-side connector 2, and the other end is connected to the clamp end to realize electrical communication between the main-side connector 1 and the tool-side connector 2.
[0046] A connecting hole 204 is provided on the mating surface of the tool-side connector 2. The size and shape of the connecting hole 204 are adapted to the connecting pin 104 of the main-side connector. The connecting hole 204 is used to ensure that the main-side connector 1 and the tool-side connector 2 can be accurately mated. The inner wall of the connecting hole 204 is smooth to reduce the resistance when the connecting pin 201 is inserted.
[0047] A second air pipe connector 205 is fixed to the air pipe of the tool-side insert 2. The size of the second air pipe connector 205 matches the air pipe interface of the pneumatic component of the clamp. The second air pipe connector 205 is used to ensure effective gas transmission and has good sealing performance to prevent gas leakage.
[0048] like Figure 5As shown, in some embodiments, two mounting holes 106 are provided on the side of the main side connector 1 away from the docking surface. The mounting holes 106 are countersunk holes. A floating base 3 is mounted on the main side connector 1 through the mounting holes 106. The floating base 3 includes a pin 301, a spring 302, a limiting piece 303, a V-shaped piece 1 304, and a V-shaped piece 2 305, wherein:
[0049] The pin 301 passes through the floating base 3 and is inserted into the mounting hole 106. A spring 302 is sleeved on the outer diameter of the pin 301. One end of the spring 302 is fixed to the bottom of the mounting hole 106, and the other end is connected to a limiting piece 303. The limiting piece 303 is fixedly connected to the inner wall of the mounting hole 106. A V-shaped piece 304 is engaged at the end of the limiting piece 303 away from the spring 302. The V-shaped piece 304 is interference-fitted with the mounting hole 106. A V-shaped piece 305 is loosely fitted below the V-shaped piece 304. The V-shaped piece 305 is sleeved on the outer diameter of the pin 301. The V-shaped piece 305 is conical. The V-shaped piece 304 and the V-shaped piece 305 fit together. The opening of the V-shaped piece 304 is larger than the diameter of the pin 301.
[0050] The fitting design of the V-shaped piece 304 and the V-shaped piece 305 allows the pin 301 to float within a certain radial range to compensate for manufacturing errors or slight offsets during docking, ensuring precise docking of the main side connector 1 and the tool side connector 2.
[0051] Working principle:
[0052] When the robotic arm needs to change to a different gripper, the robotic arm connects the main-side connector 1 to the tool-side connector 2, which is connected to the required gripper. During this process:
[0053] The connecting pin 401 is inserted into the connecting hole 204, so that the spring probe access end 201 and the spring probe 101 of the tool-side insertion 2 are on the same vertical plane. When the main-side insertion 1 and the tool-side insertion 2 are closed, the air passage self-sealing port 102 and the air passage sealing port 203 fit together to form a sealing channel. The fixing rod 401 applies force to the force-receiving rod 207, and the force-receiving rod 207 compresses the spring 209 to contract inward. A certain gap is generated between the force-receiving rod 207 and the fixing rod 206, and the air passage self-sealing port 202 opens.
[0054] The fixing rod 206 applies force to the force-receiving rod 402, which compresses the spring 403, causing it to contract inward. A certain gap is created between the force-receiving rod 402 and the fixing rod 401, opening the air passage self-sealing port 102.
[0055] When the main side connector 1 separates from the tool side connector 2, the first force rod 402 and the second force rod 207 are restored under the action of the first spring 403 and the second spring 209, cutting off the fluid flow.
[0056] When the positions of the main-side connector 1 and the tool-side connector 2 deviate, the mating closure of the main-side connector 1 and the tool-side connector 2 will cause the connecting pin 104 to be stressed. The V-shaped plate 305 will then shift under the force, and the spring 302 will be compressed. Since the floating base 3 is fixed to the robotic arm and moves relative to it, the main-side connector 1 will float due to its connection with the V-shaped plate 305, with a floating range of 2.5mm.
