Description

Technical Field

[0001] The utility model relates to the field of thickness measurement scanning frames, in particular to an intelligent O-shaped scanning frame device without sealing film. Background Art

[0002] Laser thickness gauge uses the reflection principle of laser to measure the thickness of products by measuring and observing the microscopic geometric shape of the surface of parts processed in mechanical manufacturing according to the light section method. It is a non-contact dynamic measuring instrument. It combines laser light source, photoelectric detection and computer industrial control technology to achieve online thickness measurement. It can be widely used in real-time measurement of thickness, width and profile of various materials on production lines.

[0003] A representative example is the O-type scanning test, in which the thickness sensor is installed on a moving slide rail for sliding detection. The temperature inside the thickness sensor cannot be effectively released during the back-and-forth movement and operation detection process, which will not only cause a slight deviation in the detection data, but also cause a slight vibration during the movement. The combination of the two will lead to a greater deviation in the detection data, and will also cause the sealing film on the scanning frame to loosen and fall off, resulting in errors in the detection product.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] See also Figure 1-3The utility model provides an embodiment: a sealing film-free intelligent O-type scanning frame device, comprising two control cabinets 10 and a slide rail 12, wherein the bottom of the control cabinet 10 is supported by a base 11, and the slide rail 12 is fixedly installed between the two control cabinets 10, and the control cabinet 10 is used to drive and control the slide rail 12, and an upper sliding plate 13 is slidably installed on the lower end surface of the slide rail 12 located on the upper side, and a signal receiver is fixedly installed on the upper sliding plate 13 A rectangular slip ring block 14 is slidably mounted on the slide rail member 12 at the lower side, and a protrusion 15 is provided on the upper end surface of the rectangular slip ring block 14. A breathable inner cavity 17 is provided inside the protrusion 15. The bottom of the breathable inner cavity 17 is densely provided with breathable holes, and the breathable holes penetrate the rectangular slip ring block 14. The upper end surface of the slide rail member 12 at the lower side is distributed with breathable grooves, so that the breathable holes are connected with the breathable grooves, and there will be a breathable hole in the process of sliding the rectangular slip ring block 14. In order to effectively improve the internal air circulation, an annular cylinder portion 16 is fixedly provided on the upper end surface of the raised portion 15, and a thickness sensor 20 is installed in the annular cylinder portion 16. At the same time, an annular groove 18 is provided on the side wall of the breathable inner cavity 17, and a mesh plate 19 is fixedly embedded and installed in the annular groove 18. A compression spring is connected between the bottom end surface of the thickness sensor 20 and the upper end surface of the mesh plate 19. The bottom breathable part of the breathable inner cavity 17 is spaced a distance by the annular groove 18, thereby leaving a heat dissipation space. At the same time, a compression spring is used to support the bottom of the thickness sensor 20 to maintain stability, and at the same time, the influence of friction vibration during the movement of the rectangular slip ring block 14 is reduced, so that the accuracy of the thickness sensor 20 when detecting the thickness of the object can be effectively guaranteed. At the same time, the heat dissipation space reserved at the bottom can greatly improve the air circulation during the movement of the rectangular slip ring block 14, thereby taking away the heat generated by the thickness sensor 20, and effectively avoiding the influence of high heat on the detection.

[0025] It is worth mentioning that in the present embodiment, a thread is provided on the outer end face of the annular tube portion 16, and a threaded pressing ring 21 is threadedly connected, and the threaded pressing ring 21 is covered on the upper end face of the thickness sensor 20 and abuts against the upper end face of the thickness sensor 20. The threaded pressing ring 21 is tightened and pressed onto the thickness sensor 20 to form an extrusion fixation between the compression spring at the bottom of the thickness sensor 20. At the same time, the degree to which the thickness sensor 20 is pressed downward can be adjusted by rotating the threaded pressing ring 21, thereby making the thickness sensor 20 more stable during the operation detection process.

[0026] It should be noted that in order to further improve the stability of the thickness sensor 20, a latex layer is fixedly installed on the side wall of the center hole of the above-mentioned annular tube part 16, and is abutted against the outer end face of the thickness sensor 20. The latex layer is padded on the outer end face of the thickness sensor 20, which can further isolate the conduction of vibration during the movement of the rectangular slip ring block 14 and further ensure stability.

[0027] In specific implementation, when it is necessary to detect the thickness of an object, the object to be detected is passed through the middle of the two slide rails 12. At this time, the control panel on the surface of the control cabinet 10 is used to control and start, thereby driving the rectangular slip ring block 14 and the upper sliding plate 13 to slide. At the same time, the thickness sensor 20 emits laser detection rays, which penetrate the object to be detected and are received by the signal receiver on the upper sliding plate 13, thereby detecting the thickness of the object. During the sliding process of the rectangular slip ring block 14, the air vents and the air vent grooves are interconnected, thereby effectively improving the air circulation of the air-permeable inner cavity 17. The bottom air-permeable part of the air-permeable inner cavity 17 is separated by a distance by the annular groove 18, thereby leaving a heat dissipation space, so that the air circulation can be greatly improved during the movement of the rectangular slip ring block 14, thereby taking away the heat generated by the thickness sensor 20, effectively avoiding the influence of high heat on the detection.

[0028] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
