[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] In order to enable those skilled in the art to better understand the solution of the utility model, 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 should fall within the scope of protection of the utility model.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed can also be "included" and "having"; for example, a process, method, system, product or device that can include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0018] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0019] like Figure 1 As shown, the utility model is a device for measuring the length of a magnetic ring soft lead, comprising a frame, a magnetic ring positioning mechanism is installed in the middle of the frame, and a magnetic ring pressing mechanism and a measuring mechanism are respectively arranged on both sides of the magnetic ring positioning mechanism.

[0020] The magnetic ring positioning mechanism comprises a magnetic ring positioning seat 3, on which a semicircular groove is provided for placing the magnetic ring. A magnetic ring baffle 4 is provided on the side of the magnetic ring positioning seat 3, on which a soft rope avoidance groove is provided.

[0021] The magnetic ring pressing mechanism comprises a cylinder 1, a cylinder body of the cylinder 1 is mounted on a frame, a piston end of the cylinder 1 faces a magnetic ring positioning seat 3 and a pressing plate 2 is mounted thereon.

[0022] Since the specifications and sizes of the magnetic rings are different, in order to better improve the clamping force, the magnetic ring is close to the magnetic ring baffle 4 to reduce the positioning error. The piston end of the cylinder 1 is connected to the mounting plate 2 through a transition rod group. By replacing the transition rod group, the height of the plate 2 can be easily increased to adapt to magnetic rings of different specifications.

[0023] The measuring mechanism includes a linear encoder 6, the fixed end of the linear encoder 6 is mounted on the frame, the test end of the linear encoder 6 slides on the fixed end of the linear encoder 6, a hook 5 is mounted on the test end of the linear encoder 6, and an elastic reset member is provided between the rear of the hook 5 and the frame. In this embodiment, the elastic reset member is a spring, the two ends of the spring connect the rear of the hook 5 and the frame, and the spring provides a reset elastic force for the hook 5. The spring is parallel to the axis of the linear encoder 6 to prevent the hook from getting stuck during movement.

[0024] A positioning support rod is provided in the middle of the frame, which is used to lift the magnetic ring positioning seat 3 to make room for installing the linear encoder 6, and the zero point of the linear encoder 6 is located below the magnetic ring positioning seat 3.

[0025] A cylinder mounting plate is provided on the left side of the frame to raise the cylinder 1. The piston rod of the cylinder 1 is placed at the same level as the magnetic ring 1 as much as possible to enhance the rigidity of the pressure plate 2.

[0026] The working process of the utility model is as follows:

[0027] Place the magnetic ring upright on the magnetic ring positioning seat 3, and pull the lead out horizontally through the grooved baffle on the right. Then use the cylinder to drive the pressure plate 2 to press the magnetic ring tightly, and the right end face of the magnetic ring is close to the grooved baffle 4. Then use the hook 5 to hook the terminals at the end of the lead one by one. The right side of the hook is equipped with a spring to provide tension, so that the lead is straightened. A linear encoder 6 is connected under the hook, and the length of each lead can be read by the matching industrial computer. The zero position of the encoder is calibrated regularly to achieve stable measurement. After the measurement is completed, the cylinder 1 automatically retracts, the terminal is manually lifted, and the product is unloaded. At this point, the complete measurement of the lead of a magnetic ring is completed.

[0028] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
