Description

Technical Field

[0001] This utility model relates to the field of UV energy measurement equipment technology, specifically to a sensing probe structure applied to a UV energy meter. Background Technology

[0002] A UV energy meter is a device used to measure the light intensity and energy during the ultraviolet curing process, and it is widely used in industries such as UV-cured coatings. Due to its small size, the UV energy meter can be placed on a production line for real-time measurement.

[0003] like Figure 1 As shown, the housing 1 of the existing UV energy meter is equipped with: an operation button 10, a charging interface 20, and a sensing probe 2. The sensing probe 2 is located on the front of the housing 1, with its optical axis perpendicular to the front of the housing, and is used to receive ultraviolet light incident from the front.

[0004] For example, prior art 1 (CN 214748442 U) provides an ultraviolet energy meter, the outer casing 1 including a first shell 11 and a second shell 12 that are interlocked, the second shell 12 is provided with a light sensing window 122 and a temperature sensing window 123 (see Appendix of this utility model). Figure 1 ).

[0005] However, in actual production applications, ultraviolet light sources often irradiate the object to be cured from multiple directions. For example, UV curing ovens typically contain multiple ultraviolet lamps that irradiate the workpiece from different angles, such as the front and sides. Therefore, the front sensing probe of existing UV energy meters cannot accurately reflect the light intensity and energy inside the curing oven.

[0006] In summary, existing UV energy meters have the following shortcomings.

[0007] 1. Simple probe arrangement: Existing UV energy meters only have one sensing probe on the front of the casing. The optical axis of the probe is fixed and cannot receive ultraviolet light from the side incident direction.

[0008] 2. Single optical axis direction of the probe: The optical axis direction of a single probe is only perpendicular to the front of the housing. When the ultraviolet light source shines from the side, the probe cannot effectively receive the ultraviolet light incident from the side.

[0009] Therefore, there is an urgent need for a UV energy meter that can achieve simultaneous acquisition of ultraviolet light from multiple directions, in order to solve the problems of the existing UV energy meter probes having a single arrangement and a single optical axis direction. Utility Model Content

[0010] (a) Technical problems to be solved This invention aims to solve the problems of the single orientation of the existing UV energy meter probe and the single orientation of the probe optical axis.

[0011] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides a multi-directional sensing probe structure for a UV energy meter. The UV energy meter includes a housing and an internal circuit board disposed within the housing, wherein: The outer casing has a front light-transmitting window and a side light-transmitting window. The front sensing probe is located on the front of the housing, facing outward through the front light-transmitting window, and the optical axis of the front sensing probe intersects with the front of the housing. The side sensor is located on the side of the housing and faces the outside of the housing through a side light-transmitting window. The optical axis of the side sensor intersects with the side of the housing. The front sensing probe and the side sensing probe are electrically connected to the internal circuit board through independent signal channels.

[0012] This invention proposes a novel solution different from existing technologies. It incorporates sensing probes oriented in different directions within the UV energy meter: one is a front sensing probe, positioned on the front of the casing with its optical axis intersecting the front of the casing, used to receive UV light incident from the front; the other is a side sensing probe, positioned on the side of the casing (e.g., left, right, front, or rear), with its optical axis intersecting the side of the casing, used to receive UV light incident from the side. Therefore, compared to existing technologies, this invention can simultaneously collect and measure UV energy from different directions, thus accurately reflecting the light intensity and energy within the curing oven.

[0013] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the side sensing probe is disposed at at least one side position among the left, right, front or rear sides of the housing.

[0014] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the number of side sensing probes is one or more, and the multiple side sensing probes are respectively arranged at different side positions of the outer shell.

[0015] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the angle between the optical axis direction of the front sensing probe and the optical axis direction of the side sensing probe is 60° to 180°.

[0017] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, both the front sensing probe and the side sensing probe are ultraviolet photoelectric sensors, and the sensing wavelength range of the ultraviolet photoelectric sensors is 200nm~400nm.

[0018] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, a protective sheet is provided on the outside of the front and side light-transmitting windows, and the protective sheet is made of ultraviolet-transmitting optical material.

[0019] Preferably, in the UV energy meter multi-directional sensing probe structure of this utility model, the ultraviolet-transmitting optical material is quartz glass, sapphire, or ultraviolet-transmitting plastic.

[0020] On the casing of the UV energy meter, the sensing probe receives UV energy through a light-transmitting window. A protective sheet, made of quartz glass, sapphire, or UV-transmitting plastic, is positioned outside the sensing probe at this window. This ensures efficient UV light transmission while protecting the sensing probe.

[0021] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the internal circuit board is provided with a front signal processing channel and a side signal processing channel, the front sensing probe is connected to the front signal processing channel, and the side sensing probe is connected to the side signal processing channel.

[0022] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the front signal processing channel and the side signal processing channel are independent of each other.

[0023] Preferably, according to the multi-directional sensing probe structure of the UV energy meter of this utility model, the internal circuit board is equipped with a microprocessor, which is connected to the front signal processing channel and the side signal processing channel respectively.

[0024] In this utility model, the front signal processing channel and the side signal processing channel are independent of each other. The microprocessor is connected to the front signal processing channel and the side signal processing channel respectively, so that the measurement data of the two channels can be read synchronously and the signal processing of each channel can be performed independently to ensure that the signals do not interfere with each other.

[0025] (III) Beneficial Effects The technical solution of this utility model can achieve the following beneficial effects.

[0026] First, multi-directional probe arrangement. The front sensing probe and the side sensing probe are respectively set on the front and side of the shell, and the optical axis direction intersects the front and side of the shell, thereby realizing the synchronous acquisition of ultraviolet light from multiple directions.

[0027] Second, the optical axis orientation is differentiated. The optical axes of the front sensing probe and the side sensing probe are set at an angle, allowing the two probes to receive ultraviolet light from different incident directions, thus expanding the ultraviolet light reception range.

[0028] Third, signal processing is independent. The front and side sensors are connected to independent signal processing channels, and each channel processes signals independently to ensure that the signals do not interfere with each other. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 3 To be continued Figure 8 The implementation of this utility model will be described in conjunction with specific embodiments.

[0039] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a front light-transmitting window 4 is provided on the front of the housing 1, and the front sensing probe 2 is disposed on the front of the housing 1, facing outward through the front light-transmitting window 4. The optical axis A of the front sensing probe 2 is perpendicular to the front of the housing 1, and is used to receive ultraviolet light incident from the front. In the front light-transmitting window 4, a protective sheet 5 made of quartz glass is provided on the outside of the front sensing probe 2 to ensure efficient transmission of ultraviolet light.

[0040] A side-transmitting window is provided on the side of the housing 1, and a side-sensing probe 3 is disposed on the side of the housing 1, facing outward through the side-transmitting window. The optical axis B of the side-sensing probe 3 is perpendicular to the side of the housing 1, and is used to receive ultraviolet light incident from the side. A protective sheet made of quartz glass is provided on the outside of the side-transmitting window to ensure efficient transmission of ultraviolet light. The structure of the side-transmitting window and the protective sheet are the same as those of the front-transmitting window.

[0041] In this embodiment, the optical axis direction A of the front sensing probe 2 is perpendicular to the front of the housing 1, and the optical axis direction B of the side sensing probe 3 is perpendicular to the side of the housing 1. The angle between the optical axis direction A of the front sensing probe 2 and the optical axis direction B of the side sensing probe 3 is 90°, that is, the optical axis directions of the two probes are perpendicular to each other.

[0042] In other embodiments, the optical axis direction of the sensing probe does not necessarily have to be perpendicular to the surface (front or side) of the housing; it can intersect with it. For example, the optical axis direction A of the front sensing probe 2 intersects with the front of the housing 1, and the optical axis direction B of the side sensing probe 3 intersects with the side of the housing 1. Furthermore, the angle between the optical axis direction A of the front sensing probe 2 and the optical axis direction B of the side sensing probe 3 can also be other angles. Preferably, this included angle can be adjusted within the range of 60° to 180° to accommodate different light source arrangements.

[0043] Both the front sensing probe 2 and the side sensing probe 3 are ultraviolet photoelectric sensors with a sensing wavelength range of 200nm to 400nm, capable of receiving ultraviolet light in the UV-A, UV-B, and UV-C bands.

[0044] The internal circuit board 6 is housed within the outer casing 1. For example... Figure 7 As shown, the internal circuit board 6 is equipped with a front signal processing channel 7, a side signal processing channel 8, and a microprocessor 9.

[0045] The front sensing probe 2 is connected to the front signal processing channel 7, and the side sensing probe 3 is connected to the side signal processing channel 8. The front signal processing channel 7 and the side signal processing channel 8 are independent of each other.

[0046] The microprocessor 9 on the internal circuit board 6 is connected to the front signal processing channel 7 and the side signal processing channel 8, respectively. The microprocessor 9 synchronously reads the digital signals output from the front signal processing channel 7 and the side signal processing channel 8, and calculates the cumulative ultraviolet energy and light intensity values ​​in the front and side directions, respectively.

[0047] This embodiment of the invention achieves simultaneous acquisition of multi-directional ultraviolet light by setting sensing probes on the front and side of the housing, respectively. The optical axes of the two types of probes are perpendicular to the front and side of the housing, respectively. The front and side sensing probes are connected to independent signal processing channels and store independent calibration parameters, ensuring independent signal processing and accurate measurement data.

[0048] This invention can also be implemented in other ways, for example, by providing multiple side sensing probes, each positioned on a different side of the housing. Figure 8 As shown, side sensing probes 31 and 32 are respectively set on two adjacent sides.

[0049] In addition, the sensor structure of this invention can also be equipped with a shield to protect the sensor and the protective sheet when not in use, and to prevent dust, oil and other contaminants from polluting the protective sheet.
