[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See also Figure 3-4A conveyor belt precise positioning structure comprises a conveyor belt 1, a controller electrically connected to the conveyor belt 1, and a rotating shaft 2. An encoder 3 is provided at one end of the rotating shaft 2. A distance detection device is provided on one side of the outlet of the conveyor belt 1. The distance detection device is used to detect the distance between the product 9 on the conveyor belt 1 and the distance detection device. An induction sheet 5 for confirming the stop position is provided on the edge of the conveyor belt 1. An induction switch 4 for sensing the induction sheet 5 is provided on one side of the conveyor belt 1. The encoder 3, the distance detection device, and the induction switch 4 are all electrically connected to the controller. The encoder 3 is installed on the rotating shaft 2 of the conveyor belt 1. According to the position set by the controller, The encoder 3 detects the displacement of the conveyor belt 1. When the displacement of the conveyor belt 1 reaches the displacement set by the controller, the sensor switch 4 is used to confirm whether it is accurate. That is, when the sensor switch 4 detects the sensor sheet 5, it indicates that the conveyor belt 1 has reached its position. At this time, the controller controls the conveyor belt 1 to stop to ensure the accuracy of the stopping position. When the displacement of the conveyor belt 1 reaches the displacement set by the controller, the sensor switch 4 does not detect the sensor sheet 5. The encoder 3 will continue to record the displacement of the conveyor belt 1 until the sensor switch 4 detects the sensor sheet 5. Then the conveyor belt 1 stops. At the same time, the encoder 3 feeds back to the controller and makes adjustments.

[0022] In this embodiment, a second mounting bracket 8 for mounting the induction switch 4 is provided on the bracket of the conveyor belt 1. A rectangular through hole is provided on the second mounting bracket 8. The induction switch 4 is mounted in the rectangular through hole on the second mounting bracket 8. The induction switch 4 can adjust the distance between itself and the induction sheet 5 along the rectangular through hole.

[0023] In this embodiment, the induction switch 4 is a photoelectric sensor. In other embodiments, the induction switch may be an infrared sensor, an electromagnetic sensor, etc.

[0024] In this embodiment, there are multiple sensing sheets 5, and the sensing sheets 5 are evenly spaced and arranged on the edge of the conveyor belt 1. The sensing switch 4 can sense the sensing sheets 5 on the conveyor belt 1, and can perform secondary confirmation on the positioning of the conveyor belt 1, thereby further improving the accuracy of the positioning of the conveyor belt 1. The sensing switch 4 is combined with the sensing sheets 5 to detect the operation process of the conveyor belt 1, thereby ensuring the smooth operation of the conveyor belt 1.

[0025] In this embodiment, the distance detection device includes a first mounting bracket 7 and a rangefinder 6. The rangefinder 6 is detachably connected to the first mounting bracket 7. The rangefinder 6 is connected to the first mounting bracket 7 by bolts, which facilitates the disassembly and installation of the rangefinder 6. Both ends of the first mounting bracket 7 are provided with mounting holes, which can be bolted to other fixing parts.

[0026] In this embodiment, there are two rangefinders 6, which are respectively installed at the two ends of the first mounting bracket 7, and the distance between the two rangefinders 6 is smaller than the width of the conveyor belt 1. The conveyor belt 1 will extend during operation. The distance from the stop position of the conveyor belt 1 to the rangefinder 6 is detected by the rangefinder 6 to further confirm whether the stop position of the conveyor belt is accurate; installing two rangefinders 6 at the two ends of the first mounting bracket 7 can further improve the accuracy of the rangefinder 6.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
