Abstract

Technical Field
[0001] The utility model belongs to the technical field of robots, in particular to a pneumatic follower device for a coil winding device. Background Art
[0002] In order to improve product production efficiency, reduce possible errors in production and reduce labor costs, more companies and factories are introducing automated assembly lines. Because manual labor cannot control errors in work well, in order to improve production efficiency, quality and production qualification rate, robotic arms are used for winding. When the robotic arm is winding, in order to ensure the accuracy of the robot arm's winding, avoid uneven winding gaps caused by differences in winding speeds, and compensate for uneven pulling force of the robot arm.
[0003] When winding on a winding machine, the winding trajectory is in a spiral form. In order to ensure the same winding gap and consistent slope, the wire must maintain a constant tension during the winding process. In order to solve the problem of maintaining constant tension, a pneumatic follower device for a coil winding device is proposed. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Specific examples are given below.
[0020] See also Figure 1-Figure 4The utility model provides a pneumatic follower for a coil winding device, comprising a pneumatic follower and a winding mold; the pneumatic follower comprises a wire clamping claw 5, a pneumatic slide fixed component 2, a pneumatic slide movable component 3, an upper limit sensor 1 and a lower limit sensor 4, the pneumatic slide fixed component 2 is installed with a pneumatic slide movable component 3 on the side wall; the pneumatic slide fixed component 2 is installed with an upper limit sensor 1 on the side wall; the pneumatic slide fixed component 2 is installed with a lower limit sensor 4 on the side wall; the pneumatic slide movable component 3 is installed with a wire clamping claw 5 on the side wall; the end of the wire clamping claw 5 is installed with a pneumatic scissors 6, when the winding work starts, the robot and the winding machine each operate according to their own programs, when there is a position change due to the speed difference, the movable part of the pneumatic follower can compensate for the distance change, when the compensation position is close to the lower limit sensor 4, it means that the speed of the winding mold is too fast, the lower limit sensor 4 gives a signal to the robot, and the robot speeds up at this time, when the compensation position is close to the upper limit sensor 1, It indicates that the speed of the winding mold is too slow, and the upper limit sensor 1 gives a signal to the robot. At this time, the robot slows down its running speed. During the compensation process, the gas inside the pneumatic slide can stably maintain the pressure of the internal gas constant through the pressure control valve, thereby ensuring that a constant tension can be output continuously and stably during this process, and then the speed of wire release can be kept constant. Because the gap of the coil needs to be consistent during winding, but it is difficult for the robot arm to ensure consistency when controlling the descent speed, a pneumatic follower is required. The pneumatic follower is used for adjustment. When the speed of the robot arm changes, the sensor transmits a signal to the robot, and the robot adjusts the speed. The pneumatic slide makes the tension constant, thereby ensuring the consistency of the gap of the coil. The matching speed of the winding mold remains constant to ensure the same gap of the winding. The pneumatic slide movable component 3 ensures the constant tension of wire release by controlling the constant pressure inside it. The pneumatic follower relies on the slide cylinder buffer to solve the winding asynchronism. The pneumatic follower ensures the accuracy and stability of production, and also ensures the quality of production.
[0021] Working principle: When the winding work starts, the robot and the winding machine run according to their own programs. When the position changes due to the speed difference, the movable part of the pneumatic follower can compensate for the distance change. When the compensation position is close to the lower limit sensor 4, it means that the speed of the winding mold is too fast. The lower limit sensor 4 gives a signal to the robot, and the robot speeds up. When the compensation position is close to the upper limit sensor 1, it means that the speed of the mold is too slow. The upper limit sensor 1 gives a signal to the robot, and the robot slows down. During the compensation process, the gas inside the pneumatic slide passes through the pressure The control valve can stably maintain the constant pressure of the internal gas, thereby ensuring that a constant pulling force can be continuously and stably output during the process, and thus the wire-releasing speed can be kept constant, because the gap between the coils needs to be consistent when winding, but it is difficult for the robot arm to ensure consistency when controlling the descent speed, so a pneumatic follower is required. The pneumatic follower is used for adjustment. When the speed of the robot arm changes, the sensor transmits a signal to the robot, and the robot adjusts the speed. The pneumatic slide makes the pulling force constant, thereby ensuring the consistency of the gap between the coils. The pneumatic follower ensures the accuracy and stability of production, as well as the quality of production.
