Description

Technical Field

[0001] The utility model relates to the technical field of laser distance measurement, in particular to an elastic mold frame used for a laser distance measurement sensor. Background Art

[0002] Laser ranging is the process of emitting laser pulses from a laser diode to a target. After being reflected by the target, the laser light scatters in all directions. Part of the scattered light returns to the sensor receiver and is received by the optical system and imaged onto an avalanche photodiode. An avalanche photodiode is an optical sensor with an internal amplification function. Therefore, it can detect extremely weak light signals, record and process the time from the emission of the light pulse to the return and reception, and thus determine the target distance. Lasers are widely used in the field of detection, with rich technical content and obvious impact on social production and life. At present, when a laser ranging device is used with an inkjet printer, the position of the inkjet printer needs to be determined by the size of the material. When measuring the size of the material, if the thickness of the material is too large, it is easy to block the reflector of the laser ranging device, affecting the distance measured by the sensor, reducing the wide application of the container ranging device. At the same time, the vibration generated by the motor and the inkjet printer during operation can easily cause the sensor and the reflector to shake, affecting the measurement results, thereby reducing the effect of laser ranging.

[0003] For example, the utility model patent with the publication number CN218524882U discloses a laser ranging sensor, including a device body and a support base, wherein the upper surface of the support base is fixedly connected to the lower surface of the device body; a bottom column, wherein the bottom column is provided with a plurality of bottom columns and the upper ends of the bottom columns are fixedly connected to the lower surface of the support base; a reflecting mechanism, wherein the reflecting mechanism is arranged on one side of the upper surface of the device body; a ranging base, wherein the ranging base is fixedly connected to one side of the device body; a laser mechanism, wherein the laser mechanism is arranged on the upper surface of the ranging base; and a controller, wherein the controller is fixedly connected to the side of the device body. When the device measures the size of a material, if the thickness of the material is too large, it is easy to block the reflector of the laser ranging device, thereby affecting the distance measured by the sensor and reducing the wide application of the laser ranging device. When determining the width of the material, the reflector collides with the material for a long time, which may cause the surface of the reflector to be damaged, thereby affecting the service life of the equipment. At the same time, vibration is generated during the operation of the motor and the inkjet printer, which is easy to cause the sensor and the reflector to shake, thereby affecting the measurement result and reducing the effect of the laser ranging device.
