[0001] This invention relates to the field of industrial robots, and in particular to a clamping device for industrial robots. Background Technology

[0002] Industrial robots are automated, programmable, multi-jointed mechanical devices designed for the industrial sector. They perform production tasks such as material handling, processing, and assembly through power systems and control technologies, and are core equipment for the intelligent transformation of the manufacturing industry. The gripping device of an industrial robot is the core component that connects the robot arm to the workpiece.

[0003] Traditional clamping devices use their grippers to hold workpieces. However, in working environments with poor air quality, dust, dirt, or oil easily adhere to the surface of the grippers, requiring regular manual cleaning. Furthermore, the grippers are continuously exposed to the external environment whether in working or non-working states, making it impossible to store and protect them. After prolonged periods of inactivity, a large amount of dust and grime accumulates on the gripper surface, necessitating manual cleaning before the next use, causing inconvenience.

[0035] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0036] like Figure 1-10 As shown, a gripping device for an industrial robot includes a housing 1; and further includes: The clamping jaws 4 are two in number and are symmetrically installed inside the housing 1. The housing 1 is equipped with a drive mechanism 6 for moving the two clamping jaws 4 closer to or further away from each other. Under the drive of the drive mechanism 6, the two clamping jaws 4 clamp or release the workpiece. The gripper 4 includes a fixed sleeve 402 and a movable sleeve 401 movably fitted onto the fixed sleeve; the gripper 4 specifically clamps the workpiece through the movable sleeve 401, and the movable sleeve 401 moves up and down to be stored inside the outer shell 1 or extend out from the outer shell 1.

[0037] The rinsing mechanism 5 is mounted on the movable sleeve 401. The rinsing mechanism 5 is used to rinse and clean the area around the movable sleeve 401. In conjunction with the up and down movement of the movable sleeve 401, it can rinse all parts along the length direction to ensure the cleaning effect.

[0038] The sealing component 7 is installed at the bottom opening of the housing 1, and there are two sealing components 7. The sealing component 7 is used for the opening and closing control of the bottom port of the housing 1. In the storage state, it can keep the gripper 4 in a closed protective environment.

[0039] The filter blowing assembly 3 comprises two components, which are respectively installed on the front and back of the housing 1. The air outlet of the filter blowing assembly 3 is connected to the housing 1. The filter blowing assembly 3 is used to blow clean air into the housing 1. The clean air is blown out from the bottom of the housing 1, so that the inside and bottom of the housing 1 are in a clean environment during operation.

[0040] like Figure 1 As shown, as a specific technical solution, a mounting base 2 is fixedly installed on the top of the outer shell 1, and the mounting base 2 is provided with multiple mounting holes 201. The mounting base 2 is used to fix the entire clamping device to the industrial robot.

[0041] like Figure 3 and Figure 7 As shown, as a specific technical solution, the drive mechanism 6 includes a third gear 601 and a motor 605; the motor 605 is fixedly installed inside the housing 1, and the output shaft end of the motor 605 is fixedly sleeved with the third gear 601. The top and bottom of the third gear 601 are respectively meshed with a third rack 602 and a fourth rack 603; both the third rack 602 and the fourth rack 603 have guide grooves opened in the transverse direction, and the guide grooves are connected with guide posts 604 with clearance fit. The guide posts 604 are fixedly installed inside the housing 1; the third rack 602 and the fourth rack 603 are respectively fixedly connected to the top ends of the fixing sleeves 402 of the two grippers 4.

[0042] like Figure 7 As shown, the third rack 602 is fixedly mounted with the first connecting frame 606, and the fourth rack 603 is fixedly connected with the second connecting frame 607. The first connecting frame 606 and the second connecting frame 607 are fixedly connected to the fixing sleeves 402 of the two grippers 4.

[0043] The motor 605 drives the third gear 601 to rotate. The meshing transmission between the third gear 601 and the third rack 602, and the meshing transmission between the third gear 601 and the fourth rack 603, combined with the guiding effect provided by the guide groove and the guide post 604, causes the third rack 602 and the fourth rack 603 to drive the two grippers 4 to move in opposite directions, thereby clamping or releasing the workpiece.

[0044] like Figure 8As shown, as a specific technical solution, the movable sleeve 401 is slidably sleeved onto the outer wall of the fixed sleeve 402. A transmission assembly is provided between the movable sleeve 401 and the fixed sleeve 402. The input end of the transmission assembly is connected to a pressure rod 403. The pressure rod 403 passes through a guide hole 405 opened at the top of the fixed sleeve 402, and the top end of the pressure rod 403 abuts against the top inner wall of the outer shell 1.

[0045] like Figure 4 As shown, as a specific technical solution, the top two sides of the outer shell 1 are provided with downwardly inclined walking ramps 101; the top of the pressure rod 403 is spherical.

[0046] like Figure 8-10 As shown, as a specific technical solution, the transmission assembly includes a first rack 404 and a second rack 409; the bottom end of the first rack 404 is fixedly connected to the inner wall of the bottom end of the movable sleeve 401, the top end of the first rack 404 extends into the bottom port of the fixed sleeve 402, the first rack 404 is meshed with a first gear 410, the first gear 410 is rotatably installed into the bottom port of the fixed sleeve 402, the first gear 410 is coaxially fixedly installed with a second gear 411, the side of the second gear 411 away from the first rack 404 is meshed with a second rack 409, the top end of the second rack 409 is fixedly connected to the bottom end of the pressure rod 403; the diameter of the first gear 410 is larger than the diameter of the second gear 411.

[0047] like Figure 9 As shown, as a specific technical solution, a fixing block 406 is fixedly installed on the pressure rod 403, and the fixing block 406 is slidably installed inside the fixing sleeve 402. The top of the fixing block 406 is elastically connected to the inner wall of the top of the fixing sleeve 402 by a spring 407. A stop post 408 is provided on the top of the fixing block 406, and the top of the stop post 408 is fixedly connected to the inner wall of the top of the fixing sleeve 402.

[0048] like Figure 3-4 As shown, the two grippers 4 are in the open state at this time. When gripping the workpiece, the workpiece is placed between the two grippers 4. The drive mechanism 6 drives the two grippers 4 to move closer to each other, and the movable sleeve 401 of the two grippers 4 clamps the workpiece. After gripping the workpiece, the industrial robot moves the workpiece to the desired position, and the drive mechanism 6 drives the two grippers 4 to move away from each other to release the workpiece. After the workpiece is released, the two grippers 4 return to their open state. Figure 3-4 The open state is shown; in this state, the movable sleeve 401 of the gripper 4 is located below the outer shell 1, and the pressure rod 403 on the gripper 4 is located on one side of the travel slope 101. There is a gap between the gripper 4 and the inner wall of the outer shell 1, so that the two grippers 4 have the activity space to continue to open and move away.

[0049] When the gripper 4 is in the position as Figure 3-4 In the open state shown, the drive mechanism 6 drives the gripper 4 to continue opening, and the gripper 4 moves closer to the inner wall of the outer shell 1. Meanwhile, the pressure rod 403 moves from the top inner wall of the outer shell 1 to the traveling ramp 101. The traveling ramp 101 presses the pressure rod 403 into the fixed sleeve 402 until the annular shell 505 on the movable sleeve 401 fits against the inner wall of the outer shell 1. During the above process, the pressure rod 403 drives the second rack 409 to move downward. Through the meshing transmission between the second rack 409 and the second gear 411, the second gear 411 and the first gear 410 rotate together. Then, through the meshing transmission between the first gear 410 and the first rack 404, the movable sleeve 401 moves upward. Since the diameter of the first gear 410 is larger than the diameter of the second gear 411, the movable sleeve 401 is ensured to be stored inside the outer shell 1. This achieves the retractable design of the movable sleeve 401, which can be stored and protected when not in operation.

[0050] Simultaneously, during the retraction of the aforementioned movable sleeve 401, the pressure rod 403 drives the fixing block 406 to move downwards together, while simultaneously stretching the spring 407; when the entire clamping device resumes operation, the drive mechanism 6 drives the gripper 4 to return to its original position. Figure 3-4 In the indicated state, the pressure rod 403 separates from the traveling ramp 101, and the top of the pressure rod 403 re-abuts against the inner wall of the top of the outer casing 1. Through the elastic force of the spring 407, the fixed block 406 and the pressure rod 403 move upward together. The pressure rod 403 drives the second rack 409 to move upward. Through the meshing transmission between the second rack 409 and the second gear 411, the second gear 411 and the first gear 410 rotate together. Through the meshing transmission between the first gear 410 and the first rack 404, the first rack 404 and the movable sleeve 401 move downward together, so that the movable sleeve 401 extends out from the bottom of the outer casing 1, and the fixed block 406 is in contact with the stop post 408, which blocks the movement.

[0051] like Figure 2 and Figure 5 As shown, as a specific technical solution, the sealing assembly 7 includes a sleeve plate 701 fixedly installed on the bottom port of the outer casing 1; a sliding groove 702 is provided on the sleeve plate 701, a movable plate 703 is slidably installed in the sliding groove 702, and a telescopic rod 704 is fixedly installed inside the sliding groove 702, the telescopic rod 704 being fixedly connected to the movable plate 703. The telescopic rod 704 is an electric push rod.

[0052] The sealing assembly 7 is used for opening and closing control of the bottom port of the housing 1; in the working state, the bottom port of the housing 1 is in the open state, that is, a gap is formed between the two movable plates 703, such as... Figure 5As shown; in the non-working state, the movable sleeve 401 is retracted into the outer shell 1. After retraction, the telescopic rod 704 extends, causing the movable plate 703 to slide against the slide groove 702, so that the movable plate 703 extends out of the slide groove 702 until the movable plates 703 of the two sealing components 7 are in contact with each other, thus achieving sealing; before the movable sleeve 401 extends out from the bottom of the outer shell 1 again, the telescopic rod 704 retracts, causing the movable plate 703 to be retracted into the slide groove 702, returning to the original position. Figure 5 As shown, after the two movable plates 703 form a gap, the movable sleeve 401 extends and can be restored to the working state.

[0053] Through the above design, the entire clamping device can switch between working and non-working states. In the working state, it can clamp the workpiece normally. In the non-working state, the gripper 4 can be stored, and the bottom port of the outer shell 1 is sealed to provide closed protection for the gripper 4, so as to prevent dust and dirt from adhering to the gripper 4 in the non-working state, and to prevent dust and dirt from entering the outer shell 1.

[0054] like Figure 2 As shown, as a specific technical solution, the filter blowing assembly 3 includes a frame 301; one side of the frame 301 is connected to the outer shell 1, and multiple fans 303 are fixedly installed inside the frame 301. A filter screen 302 is provided on the side of the frame 301 away from the outer shell 1, and a filter 304 is provided on the side of the frame 301 connected to the outer shell 1. The filter 304 is a high-efficiency filter 304.

[0055] When the entire clamping device is in operation, the filter blowing assembly 3 can blow clean air into the housing 1, creating positive pressure at the bottom port of the housing 1. This prevents dust and dirt from entering the housing 1 through the bottom port, thus avoiding any impact on the internal components and ensuring internal cleanliness.

[0056] The specific operation of the filter blowing assembly 3 is as follows: the blower 303 generates a blowing airflow, which causes the outside air to be filtered by the filter screen 302 and then filtered again by the filter 304 before entering the housing 1, thereby ensuring that clean airflow is blown into the housing 1.

[0057] like Figure 10 As shown, as a specific technical solution, the flushing mechanism 5 includes an annular shell 505; the annular shell 505 is sleeved on the movable sleeve 401, and a collar 508 is fixedly installed on the top of the annular shell 505. The inner ring of the collar 508 is connected to the outer wall of the movable sleeve 401 with a clearance fit. Several flushing nozzles 509 are evenly installed around the inner ring of the annular shell 505, and an infusion tubing is connected to the annular shell 505.

[0058] like Figure 3 and Figure 6 As shown, as a specific technical solution, the infusion fitting includes a connecting pipe 501 fixedly installed on the outer wall of the outer casing 1. One end of the connecting pipe 501 is fixedly connected to a tee pipe 503, and the other end of the connecting pipe 501 is fixedly connected to a spiral flexible tube 504. One end of the spiral flexible tube 504 is fixedly connected to an annular shell 505, and the spiral flexible tube 504 communicates with the annular shell 505. A storage cylinder 502 is fixedly installed on both sides of the outer casing 1, and one side of the spiral flexible tube 504 is embedded in the storage cylinder 502. The connection point between the spiral flexible tube 504 and the connecting pipe 501 is fixedly connected to the storage cylinder 502. The tee pipe 503 is connected to an external infusion supply device.

[0059] like Figure 3 , Figure 4 and Figure 6 As shown, as a specific technical solution, a guide sleeve 506 is fixedly installed on the back of the annular shell 505; a horizontally arranged guide rod 507 is fixedly installed inside the outer shell 1, and the guide rod 507 is slidably sleeved with the guide sleeve 506.

[0060] When the clamping device switches from the working state to the non-working state, the movable sleeve 401 moves into the outer shell 1 for storage. The movable sleeve 401 moves upward about the annular shell 505 and moves closer to the inner side wall of the outer shell 1. The movable sleeve 401 drives the annular shell 505 to move laterally together, and is guided by the guide rod 507 and the guide sleeve 506, so that the movable sleeve 401 moves upward only about the annular shell 505. When dirt adheres to the surface of the movable sleeve 401 and needs to be cleaned, the liquid supply device injects cleaning liquid into the three-way pipe 503. The cleaning liquid is delivered into the annular shell 505 through the three-way pipe 503, the connecting pipe 501, and the spiral hose 504, and then sprayed out from the rinsing nozzle 509 to rinse and clean the circumference of the movable sleeve 401 to ensure the cleanliness of the surface.

[0061] Through the above, the entire device has the function of cleaning the gripper 4, and after cleaning the gripper 4, it is dried by blowing air through the filter blowing assembly 3. After drying, the bottom port of the outer shell 1 is sealed.

[0062] The spiral hose 504 is designed to allow for the left and right movement of the gripper 4, ensuring that the rinsing mechanism 5 continues to perform rinsing operations while the gripper 4 moves left and right.

[0063] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
