AI Technical Summary
The independent flow cell setting of traditional fiber optic online concentration analyzers causes fiber displacement, resulting in fluctuations in measurement data. Furthermore, the fiber optic cable is susceptible to human operation, leading to measurement anomalies.
Design a flow cell built-in cabinet that integrates the flow cell, fan and electric heating plate into the cabinet body, and installs the optical fiber on the outside of the cabinet. The temperature is controlled by internal heating to avoid the optical fiber being affected by the outside.
It improves the stability of spectral acquisition, prevents leakage in the flow cell from corroding internal components, and avoids measurement anomalies caused by touching the optical fiber.

Description
TECHNICAL FIELD
[0001] The utility model relates to a flow cell built-in type cabinet matched with near-infrared concentration online analysis. BACKGROUND
[0002] The online concentration analyzer in semiconductor wet process is used for accurately measuring cleaning liquid concentration. The online concentration analyzer of optical fiber type is usually composed of four structures of optical fiber, flow cell, near-infrared box and computer. The traditional online concentration analyzer of optical fiber type is placed beside the main equipment as an accessory equipment, and the flow cell is independent outside, so that when moving, the optical fiber is displaced to cause light transmission fluctuation, thereby causing measurement data fluctuation. Therefore, there is the problem of abnormal concentration measurement caused by personnel operation touching the optical fiber. SUMMARY
[0003] The utility model discloses a flow cell built-in type cabinet matched with near-infrared concentration online analysis.
[0004] The utility model discloses the technical scheme has:
[0005] A flow cell built-in type cabinet matched with near-infrared concentration online analysis, including flow cell and cabinet, be equipped with fan, electric heating plate and independent installation room in the cabinet, the flow cell is placed in the installation room, and the fan and electric heating plate are placed outside the installation room.
[0006] Further, the installation room is fixed by profile board.
[0007] Further, the outer wall of the cabinet is equipped with a heat dissipation window.
[0008] The utility model has the advantages of:
[0009] The utility model integrates the flow cell in the inside of cabinet, places the cabinet in the inside of matched main equipment when using, controls constant temperature through internal heating, improves the stability of collected spectrum, places the optical fiber in the cabinet and outside the installation room (that is, the online concentration analyzer of optical fiber type is all installed in the cabinet and is placed outside the installation room), is not exposed to the external environment, avoids the spectrum collection anomaly caused by personnel operation touching the optical fiber. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is the internal structure diagram of cabinet.
[0011] Figure 2 It is the external structure diagram of cabinet. DETAILED DESCRIPTION
[0012] The utility model will be further explained in connection with the drawings.
[0013] As Figure 1 And Figure 2 The utility model discloses a flow cell built-in type cabinet matched with near-infrared concentration online analysis, including the cabinet body 1, is equipped with fan 2, electric heating plate 3 and independent installation room in the cabinet body 1, and the flow cell 4 is placed in the installation room. When using, light source, optical path switcher and spectrometer are all installed in the cabinet body 1 and are placed outside the installation room, and the flow cell unit is placed in a space alone, which prevents the flow cell cavity from leaking and corroding the optical and circuit elements inside the box.
[0014] The utility model discloses a fan 2 and electric heating plate 3 are equipped in the cabinet body 1, is equipped with the heat dissipation window 11 on the outer wall of the cabinet body 1, can make the inside temperature of the box reach constant, places two heating plates as heating source, and the fan makes internal air circulation, and the temperature in the cabinet is monitored through the circuit mainboard with temperature sensor to control the heating plate and heat, makes the inside control of the box in 0.1 DEG C's deviation.
[0015] The installation room is fixed by sectional material board, and the installation room can use modular design, which is convenient to assemble.
[0016] The above only is the preferred implementation of the utility model, should point out, for the ordinary skill in the art of the present technology, on the premise of not departing from the principle of the utility model, still can make a number of improvements, these improvements also should be regarded as the protection range of the utility model.
