Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a mechanical hand tire contact feedback device. Background Art

[0002] During the tire production process, a robotic arm is used to grab the initially formed tire blank and place it in the vulcanizer for vulcanization. During this process, the blank can get stuck in the vulcanization bladder or tilt when placed. If the operator fails to detect this in time, the vulcanizer mold may damage the blank or bladder, resulting in product failure or vulcanizer failure. Currently, there is no effective solution in the industry, relying on manual monitoring and immediate shutdown upon detection of any issues, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to solve the above technical problems, the utility model discloses a robot tire touch feedback device, including a connecting seat, a touch rod and a proximity switch. The touch rod is arranged on the front side of the connecting seat and one end of the two is rotatably connected. The other end of the connecting seat is fixedly connected to the robot gripping plate through a connecting assembly. A through hole is provided on the connecting seat. The proximity switch is provided on the connecting seat and corresponds to the position of the through hole. A sensing block is provided on the upper side of the touch rod, and the sensing block rotates correspondingly to the position of the through hole.

[0004] Furthermore, the connecting seat is provided with an arc-shaped limiting groove, and the touch rod is provided with a limiting block, and the limiting block is slidably arranged in the arc-shaped limiting groove.

[0005] Furthermore, the connecting assembly includes a connecting plate and a bolt. The connecting plate is fixedly arranged at the end of the connecting seat, and a bolt is provided on each side of the connecting plate.

[0006] Furthermore, the connecting seat is rotatably connected to one end of the touch rod via a roller bearing.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The connecting seat of the utility model is fixedly installed on the gripping plate of the robot. When grabbing the tire, the touch rod contacts the tire bead. If the bladder has not shrunk completely and the tire embryo is stuck with the bladder, or the tire is not installed correctly and the tire embryo is skewed, the touch rod will be further lifted upward and trigger the proximity switch. At this time, the robot grabs the tire embryo and separates it from the center mechanism, and stops the mold closing action to prevent damage to the bladder, and an alarm is issued to prompt manual intervention.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0018] like Figure 1-2As shown, the manipulator tire touch feedback device in this embodiment includes a connecting base 1, a touch rod 2 and a proximity switch 3. The touch rod 2 is arranged on the front side of the connecting base 1 and one end of the two is rotatably connected through a roller bearing 4. The other end of the connecting base 1 is fixedly connected to the manipulator gripping plate through a connecting assembly; wherein, the connecting assembly includes a connecting plate 5 and a bolt 6. The connecting plate 5 is fixedly arranged at the end of the connecting base 1, and a bolt 6 is provided on each side of the connecting plate 5.

[0019] A through hole 7 is provided on the connecting base 1 , and the proximity switch 3 is arranged on the connecting base 1 and corresponds to the position of the through hole 7 . A sensing block 8 is provided on the upper side of the touch rod 2 , and the sensing block 8 rotates correspondingly to the position of the through hole 7 .

[0020] The connecting seat 1 is further provided with an arc-shaped limiting groove 9 , and the touch rod 2 is provided with a limiting block 10 , which is slidably arranged in the arc-shaped limiting groove 9 .

[0021] like Figure 3 As shown, when the present invention is used, the device is installed and fixed on the robot gripper through the connecting assembly. In the initial state, the touch rod 2 is located at position A, and the sensing block 8 corresponds to the proximity switch 3.

[0022] When the manipulator is gripping the tire, the front end bottom of the feeler rod 2 contacts the tire bead and is lifted upward, and rotated to position B. At this time, the sensing block 8 is disengaged from the proximity switch 3.

[0023] When the vulcanizer's laser ranging system detects the shrinkage of the curing bladder, the robot can transfer the tire blank into the vulcanizer and begin loading. If the bladder has not completely shrunk, causing the tire blank to become stuck, or if the tire is loaded incorrectly, causing the tire blank to tilt, the feeler rod 2 will be further lifted upward and rotated to position C. At this time, the feeler rod 2 will trigger proximity switch 3 again, which transmits an electrical signal to the vulcanizer's main control program, instructing the robot to grab the tire blank and separate it from the center mechanism. At the same time, further mold clamping action will be stopped to prevent damage to the bladder, and an alarm will be triggered to prompt manual intervention.

[0024] The above method can realize automatic feedback and warning of tire blank position during the process of robot grasping and installing tire, which not only reduces the labor intensity of staff, but also can avoid failure in time and ensure product quality.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
