[0005] The light strip meter detection wheel is used in the light strip meter detection mechanism, and is characterized in that a clamping groove arranged along its circumference is formed on the side wall of the detection wheel, and the clamping groove corresponds to the shape of the LED light strip;

The LED light strip sent from the detection wheel will pass through the sensing position of the running sensor and then enter the receiving roller;

[0024] See also Figure 1 In the embodiment of the utility model, a meter-counting detection wheel for a light strip is provided, which is applied to a meter-counting detection mechanism. A clamping groove 61 arranged along its circumference is formed on the side wall of the detection wheel 6, and the clamping groove 61 corresponds to the shape of the LED light strip A. In the process of tearing the film and feeding the LED light strip A, Figure 4 As shown, the LED light strip A in contact with the detection wheel 6 will be embedded in the card contact and tightly engaged with it, thereby realizing the counting measurement of irregular-shaped light strips (or special-shaped light strips). Regardless of whether the LED light strip A is outputting or reflowing, the detection wheel 6 can keep synchronous rotation with the LED light strip A, thereby ensuring the measurement accuracy of the length of the LED light strip A.

[0025] A group of magnetic sensors 62 are arranged at the end surface of the detection wheel 6. The magnetic sensors 62 are arranged on the circumference of the end surface of the detection wheel 6. The detection equipment can identify the number of rotations of the detection wheel 6 by detecting the magnetic sensors 62, thereby converting the measurement of the number of counting points at a fixed frequency into a length measurement to realize the measurement of the LED light strip A.

[0026] See also Figure 2-3 In order to realize the application of the detection wheel 6, the present embodiment also provides an automatic film tearing meter machine with a detection wheel for use in the film tearing and length measurement of the flexible LED light strip A; it comprises: a mechanism bracket 1 and a feeding roller 2, a meter (not shown) and a receiving roller 3 arranged on the mechanism bracket 1;

[0027] The LED light strip A is pulled out from the feeding roller 2, guided by the guide wheel shaft 4, and rolled up to the receiving roller 3 through the meter counter. During the rolling process, the LED light strip A and the protective film on the light strip are peeled off, and the rolling work is performed separately, thereby realizing the film tearing work of the LED light strip A. The receiving roller 3 is an active roller, which is driven by a motor driving device;

[0028] The meter counter includes: a detection wheel 6 and a detection unit (not shown) for realizing detection, wherein the detection wheel 6 is arranged in the material transfer path between the feeding roller 2 and the receiving roller 3; in the process of the feeding roller 2 tearing the film and transferring the material to the receiving roller 3, the LED light strip A will come into contact with the detection wheel 6 of the meter counter, thereby driving the detection wheel 6 to rotate, and in the process of rotation, each time the detection wheel 6 rotates one circle, the magnetic sensor 62 on the detection wheel 6 will sense the detection position of the detection unit once, and the detection unit converts the measurement of the number of counting points at a fixed frequency into the measurement of the length, thereby measuring the length of the light strip passing through the detection wheel 6;

[0029] The card slot 61 on the detection wheel 6 is used to make the LED light strip A in contact with the detection wheel 6 embedded in the card contact, ensuring that the detection wheel 6 can rotate synchronously with the LED light strip A, thereby ensuring the measurement accuracy of the length of the LED light strip A.

[0030] Furthermore, belt pressure rollers 5 are respectively provided on both sides of the detection wheel 6, and the belt pressure rollers 5 are located at the upper oblique side of the detection wheel 6, and the LED light strip A is sent out through the gap between the belt pressure rollers 5 and the detection wheel 6; during the operation, the LED light strip A is pressed down by the belt pressure rollers 5 to ensure that the LED light strip A can be inserted into the card contact of the detection wheel 6, thereby improving the accuracy of the length measurement and detection of the LED light strip A.

[0031] Furthermore, the meter counter also includes: a set of measuring displays 7 for realizing length measurement display, and the measuring display 7 is installed on the mechanism bracket 1. The staff can intuitively know the length of the LED light strip A fed into the receiving roller 3 in real time from the measuring display 7.

[0032] Furthermore, a set of running sensors 8 are installed on the mechanism bracket 1. The running sensors 8 are arranged between the meter counter and the receiving roller 3. The LED light strip A sent out from the detection wheel 6 will pass through the sensing position of the running sensors 8 and then enter the receiving roller 3.

[0033] The running sensor 8 is connected to the motor drive device of the receiving roller 3 through electrical signals. When the running sensor 8 detects that there is an LED light strip A at its sensing position, the running sensor 8 will send a working signal to the motor drive device of the receiving roller 3, and the controller will continue to work. Similarly, when there is no LED light strip A at its sensing position, the running sensor 8 will control the motor drive device of the receiving roller 3 to stop working to avoid idling.

[0034] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
