Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a small-sized separated diffuse reflection photoelectric switch, in particular to an improvement of a sensing head of a small-sized separated diffuse reflection photoelectric switch. Background Art
[0002] Diffuse reflection photoelectric switch uses the reflection of light from the detected object to detect the existence of the object. The detected object can be any reflective object. It is widely used in the field of automation for detecting the existence of objects, positioning, counting and other different scenarios. Since the separated diffuse reflection photoelectric switch has a smaller sensor head and a smaller switch body, it has higher flexibility and can be used in more complex and narrow spaces.
[0003] The separate diffuse reflection photoelectric switch sensor heads on the market currently have high material costs, short detection distances, complex manufacturing processes, and long production cycles. Since the several receiving optical fibers surrounding the light-emitting tube are impregnated with resin glue and then dried and polished many times, dust and sewage will be generated, which involves environmental pollution issues. In winter, the temperature is low and the glue does not dry, so the workshop has to be heated, resulting in a long production cycle, which limits production output, increases production costs and difficulty, and also brings about environmental pollution issues. Utility Model Content
[0004] The purpose of the utility model is to overcome the defects and shortcomings of the prior art and to provide a separate diffuse reflection photoelectric switch sensor head, which has the advantages of long sensing distance, pollution-free production, low material cost, short production cycle, and production is not affected by weather temperature, which greatly reduces product cost and shortens production cycle as a whole.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a sensor head tube body 1, an optical fiber 7, an electric wire 8, and a fixed clamp column 9. The sensor head tube body 1 includes: an outer tube 11, a light guide 12, a light-emitting tube 13, an assembly part 14, a convex mirror 15, a connecting part 16, and a fixing hole 161 is provided on the connecting part 16. The outer tube 11 in the tube body is a threaded metal tube on the outside, and a light guide 12 is arranged inside. One end of the light guide 12 is a round tube 121, and the other end is an eccentric inner hollow cone 123. A small hole 124 for the power line to pass through is arranged at the lower part of the cone. The end of the inner hollow cone is a small cylinder 122. Except for the two end faces, the inner and outer surfaces of other parts of the light guide 12 are plated with optical films to reduce light loss. On the right side of the light guide 12 is a connector 16, which is connected to the optical fiber 7 through the connector 16. Compared with the previous complex production process of using a number of small optical fibers to surround the light-emitting tube and then dipping and drying it with resin glue and then grinding and polishing it many times, the material cost is greatly reduced and the production cycle is shortened, and the production is not affected by weather temperature.
[0006] The light guide 12 has an assembly part 14 inside. On the left side of the inner hole of the assembly part 14 are two convex mirrors 15, and on the right side is a light-emitting tube 13. The wire 8 is connected to the light-emitting tube 13 through the small hole of the light guide 12. The first convex mirror close to the light-emitting tube 13 fully receives the light emitted by the light-emitting tube 13 and reduces the divergence of the light beam. The second convex mirror is used to adjust the angle of the light to form parallel light or focal light, thereby improving the utilization rate of light and increasing the sensing distance, solving the defect of using only one convex mirror before: if the convex mirror is close to the light-emitting tube, the light utilization rate is high, but it is too difficult to adjust the light angle, and the performance requirements of the convex mirror are extremely high; if the convex mirror is far away from the light-emitting tube, it is easy to adjust the light angle, but the light utilization rate is too low.
[0007] The optical fiber 7 is inserted into the upper part of the connector 16, and the electric wire 8 is inserted into the lower part. A penetrating fixing hole 161 is provided in the middle. The fixing hole 161 is provided with a fixing clamp 9. One end of the fixing clamp 9 is a conical structure. The fixing clamp 9 is inserted to clamp the outer skin of the optical fiber 7 and the electric wire 8 to fix them, thereby greatly simplifying the production process and shortening the production cycle.
[0008] After adopting the above technical scheme, the beneficial effects of the utility model are: it has a longer detection distance, reduces product material costs, greatly saves labor demand and shortens production cycle, avoids environmental pollution problems, and greatly reduces overall production costs and use costs.

The second convex mirror is used to adjust the angle of the light to form parallel light or focal light, thereby improving the utilization rate of light and increasing the sensing distance, solving the defect of using only one convex mirror before: if the convex mirror is close to the light-emitting tube, the light utilization rate is high, but it is too difficult to adjust the light angle, and the performance requirements of the convex mirror are extremely high; if the convex mirror is far away from the light-emitting tube, it is easy to adjust the light angle, but the light utilization rate is too low.
