Description

Technical Field

[0001] The utility model relates to the technical field of spectrometer structures, in particular to a mounting mechanism for a CCD camera. Background Art

[0002] As the most important core detector of the ICP full-spectrum direct-reading spectrometer, the CCD camera mainly collects the full-spectrum signal and detects the intensity of the sample elements. During the ICP optical path debugging process, the position of the CCD camera will affect the focal length change of the ICP optical path spectrometer. Even slight changes will have a great impact on the detection signal. The existing CCD camera is fixed relative to the ICP light chamber and cannot be adjusted, which will affect the detection signal. Therefore, it is urgent to develop a mounting mechanism with an adjustable distance between the CCD camera and the ICP light chamber. Utility Model Content

[0003] In response to the above problems, the present invention provides a mounting mechanism for a CCD camera, which enables fine adjustment of the distance between the CCD camera and the ICP light chamber, thereby ensuring stable and reliable input of the detection signal.

[0004] A mounting mechanism for a CCD camera, which is mounted on the outside of an ICP light chamber, wherein the ICP light chamber is pre-set with a mounting notch, is characterized in that it comprises:

[0005] The mounting frame includes a vertical connection frame and a horizontal support plate. The vertical connection frame is fixed to the outer periphery of the mounting notch and is provided with a CCD camera mounting port. The horizontal support plate is arranged horizontally.

[0006] CCD camera;

[0007] The sliding seat includes a side convex guide block and a side convex locking guide piece;

[0008] A frame rail comprising a concave track in the center of the upper surface and a locking bolt on one side;

[0009] and a drive rod;

[0010] The bottom of the frame rail is fixed to the upper surface of the horizontal support plate, the base of the CCD camera is fixed to the upper surface of the slide, the bottom slide rail part of the slide is fitted in the recessed track, and the recessed track is arranged in a straight line along the direction approaching or away from the IPC light chamber, and a side convex guide block is provided at one end of the slide away from the IPC light chamber, the driving rod is fixedly inserted in the axial positioning hole of the side convex guide block, and the driving rod drives the slide and the CCD camera to move in a straight line along the recessed track, and the locking guide piece includes a waist-shaped guide hole, and the bolt end of the locking bolt passes through the waist-shaped guide hole and is fixedly inserted in the corresponding locking hole. When the position of the CCD camera relative to the IPC light chamber is not fixed, a distance is left between the bolt head of the locking bolt and the outer surface of the locking guide piece, and the waist-shaped guide hole ensures that the CCD camera can only perform guided movement operations within the guide interval.

[0011] It is further characterized by:

[0012] It also includes a limit stop, which is fixed on one side of the frame track corresponding to the side convex guide block, and is used to limit the innermost end of the driving rod;

[0013] The limit stop includes a mounting seat and a stop rod. The mounting seat is fixed to the side of the frame rail. The stop rod is fixed to the positioning mounting hole of the mounting seat and protrudes toward the end of the driving rod. The stop rod can be adjusted in length as needed to ensure reliable installation of the CCD camera.

[0014] The end of the driving rod away from the IPC light chamber is provided with a grip portion to ensure convenient and quick operation by the operator;

[0015] The bolt head of the locking bolt is a locking gripping structure to ensure reliable locking.

[0016] After adopting the above technical solution, when the position of the CCD camera relative to the IPC light chamber is not fixed, a gap is left between the bolt head of the locking bolt and the outer surface of the locking guide piece. The driving rod drives the CCD camera to move linearly along the concave track to adapt to the optimal focal length of the optical path. When the optimal position is adjusted, the locking screw is tightened so that the bolt head is reliably pressed against the locking guide piece; this allows the distance of the CCD camera relative to the ICP light chamber to be fine-tuned, ensuring stable and reliable input of the detection signal.

DETAILED DESCRIPTION

[0023] See Figure 1-Figure 4 :A mounting mechanism for a CCD camera is mounted on the outside of an ICP light chamber 10, which has a mounting notch.

[0024] A mounting mechanism for a CCD camera, comprising a mounting frame 20, a CCD camera 30, a slide 40, a frame rail 50, and a drive rod 60;

[0025] The mounting frame 20 includes a vertical connection frame 21 and a horizontal support plate 22. The vertical connection frame 21 is fixed to the outer periphery of the mounting notch and is provided with a CCD camera mounting port. The horizontal support plate 22 is arranged horizontally.

[0026] The slide 40 includes a side-convex guide block 41 and a side-convex locking guide piece 42;

[0027] The frame rail 50 includes a concave track 51 in the center of the upper surface and a locking bolt 52 on one side;

[0028] The bottom of the frame rail 50 is fixed to the upper surface of the horizontal support plate 22, the base of the CCD camera 30 is fixed to the upper surface of the slide 40, the bottom rail portion 43 of the slide 40 is fitted into the concave rail 51, and the concave rail 51 is arranged in a straight line in the direction of approaching or moving away from the IPC light chamber 10. A side convex guide block 41 is provided on one end of the slide 40 away from the IPC light chamber 10, and the driving rod 60 is fixedly inserted into the axial positioning hole 411 of the side convex guide block 41. The driving rod 60 drives the slide 4 0. The CCD camera 30 is arranged to move linearly along the concave track 51. The locking guide plate 42 includes a waist-shaped guide hole 421. The bolt end 521 of the locking bolt 52 passes through the waist-shaped guide hole 421 and is fixedly inserted into the corresponding locking hole. When the position of the CCD camera 30 relative to the IPC light chamber 10 is not fixed, a distance is left between the bolt head 522 of the locking bolt 52 and the outer surface of the locking guide plate 42. The waist-shaped guide hole 421 ensures that the CCD camera 30 can only perform guided movement operations within the guiding range.

[0029] During specific implementation, it also includes a limit stop 70. The frame rail 50 is fixed with a limit stop 70 on one side corresponding to the side convex guide block 41. The limit stop 70 is used to limit the innermost end of the drive rod 60; the limit stop 70 includes a mounting seat 71 and a stop rod 72. The mounting seat 71 is fixed on one side of the frame rail 50, and the stop rod 72 is fixed to the positioning mounting hole of the mounting seat 71 and protrudes toward the end of the drive rod 60. The stop rod 72 is adjusted in length as needed to ensure reliable installation of the CCD camera 30.

[0030] In a preferred embodiment, the stop rod 72 is a screw rod, which is threadedly connected to the threaded hole of the mounting base 71. According to the position of the driving rod 60, the end of the stop rod 72 always fits the top of the driving rod 60 to ensure that the position of the CCD camera 30 is stable and reliable.

[0031] In specific implementation, a grip portion 61 is provided at one end of the driving rod 60 away from the IPC light chamber 10 to ensure convenient and quick operation by the operator;

[0032] The bolt head 522 of the locking bolt 52 is a locking gripping structure to ensure reliable locking.

[0033] Its working principle is as follows: When the position of the CCD camera relative to the IPC light chamber is not fixed, a gap is left between the bolt head of the locking bolt and the outer surface of the locking guide piece. The driving rod drives the CCD camera to move linearly along the concave track to adapt to the optimal focal length of the optical path. When the optimal position is adjusted, the locking screw is tightened so that the bolt head is reliably pressed against the locking guide piece; this allows the distance of the CCD camera relative to the ICP light chamber to be fine-tuned, ensuring stable and reliable input of the detection signal.
