[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The energy-dispersive X-ray fluorescence spectroscopy detection device capable of intelligently switching between automatic and manual modes according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] like Figures 1 to 6 As shown, the energy dispersive X-ray fluorescence spectrometer with intelligent switching between automatic and manual modes according to an embodiment of the present invention includes a main unit 10, an automatic sample feeding box 20, and a manual sample feeding box 30.

[0045] The main unit 10 includes a body 11, a controller located within the body 11, and an operation screen 12 connected to the controller. A sample carrier is located at the top of the body 11. An automatic sample dispenser 20 is used to load samples and is installed on the sample carrier. A manual sample dispenser 30 is used to load samples and is installed on the sample carrier. The controller identifies whether the automatic sample dispenser 20 or the manual sample dispenser 30 is installed on the carrier, and based on the identification result, determines the automatic or manual sample dispensing mode, and displays the corresponding mode's operation interface on the operation screen 12.

[0046] In other words, for small, regular samples requiring batch testing, the automatic sample testing mode can be selected. For example... Figure 3As shown, the automatic sample dispenser 20 is placed on the body 11 of the main unit 10, the sample injection system 40 is positioned in the corresponding position, and sample injection is performed. The controller can recognize the automatic sample dispenser 20 and determine that it is in automatic sampling mode, then adjusts the operation screen 12 to automatic sampling mode for user convenience. For some irregularly shaped or single-variety samples, a manual sampling mode can be selected. For example, using... Figure 5 and 6 The manual sample feeding box 30 is loaded with samples. If the controller recognizes that it is the manual sample feeding box 30, then the control panel 12 is set to manual sample measurement mode.

[0047] In one embodiment of the present invention, the controller can communicate with the automatic sample feeding box 20 and the manual sample feeding box 30. The automatic and manual sample feeding boxes 20 and 30 can actively inform the controller which mode to use. Alternatively, the controller can communicate with an identification module, which can identify whether it is a manual or automatic mode based on the box's external structure. Alternatively, it can determine whether the automatic or manual sample feeding box 20 is being used based on changes in the resistance of the connected interface. This application does not limit the identification method.

[0048] Therefore, the energy-dispersive X-ray fluorescence spectrometer with intelligent switching between automatic and manual modes according to embodiments of the present invention integrates two operating modes into one, allowing users to select the appropriate operating mode as needed. Furthermore, the device can automatically identify the sample measurement mode and display the corresponding mode's operating interface on the screen, making sample measurement simpler and more convenient for users. Compared to non-integrated devices, this reduces costs, improves operation, and increases testing efficiency.

[0049] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the automatic sample dispenser 20 includes a housing 21, a base plate 22, and a door cover 24. The top of the housing 21 has a through-hole 211 for conveying samples, and a receiving cavity is formed within the housing 21. The base plate 22 is fixed within the receiving cavity and has a cavity 23 with one open end. The opening of the cavity 23 is aligned with the through-hole 211, and the cavity 23 is used to install a sample cup 50 and can shield X-ray radiation. The door cover 24 is located within the receiving cavity, with one end rotatably connected to the base plate 22 and the other end facing the through-hole 211. When the door cover 24 rotates, it either seals or opens the through-hole 211. This structure facilitates the opening and closing of the door cover 24, making sample feeding convenient.

[0050] In one embodiment of the present invention, the cavity 23 may also be provided with an identification switch 231 for identifying whether there is a sample in the sample cup 50 and communicating with the controller so that the controller can execute the detection mode.

[0051] In one embodiment of the present invention, the automatic sample dispenser 20 further includes a mounting base 25, a drive mechanism 26 (e.g., a stepper motor), and a photoelectric switch 27. The mounting base 25 is disposed on a base plate 22. The drive mechanism 26 is mounted on the mounting base 25 and connected to a door cover 24, used to drive the door cover 24 to rotate. The photoelectric switch 27 is mounted on the mounting base 25 and connected to the drive mechanism 26. The photoelectric switch can be triggered by a photoelectric switch trigger piece 29 and used to provide a switching signal. The photoelectric switch 27 is electrically connected to a controller, which controls the drive mechanism 26 to operate, causing the door cover 24 to either seal or open the through hole 211.

[0052] In other words, the automatic control of the door cover 24 is achieved by communicating between the controller and the photoelectric switch 27, and the photoelectric switch 27 and the drive mechanism 26, which saves time and effort in operation.

[0053] In one embodiment of the present invention, a guide rail 251 and a rotating shaft 252 may also be provided on the mounting base 25. The guide rail 251 serves to provide a moving carrier. The rotating shaft 252 is connected to one end of the door cover plate 24 and serves a guiding function.

[0054] In one embodiment of the present invention, the automatic sample box 20 further includes a signal transceiver 28, which is electrically connected to the photoelectric switch 27 and the controller, for receiving or sending signals.

[0055] In one embodiment of the present invention, a positioning collar 212 is provided on the outer periphery of the through hole 211 for positioning the sample injection system 40, so as to facilitate the precise injection of the sample injection system 40.

[0056] In one embodiment of the present invention, a handle 213 is provided on the housing 21. For example... Figure 1 As shown, there can be two handles 213, which makes it easy to take the entire box out.

[0057] In one embodiment of the present invention, the manual sample box 30 is provided with a serial port signal interface 31 for connection with the controller. Communication with the controller of the host 10 is realized through the serial port signal interface 31.

[0058] In one embodiment of the present invention, the manual sample feeding box 30 includes an upper box body 32 and a lower box body 33. The upper box body 32 has a first chamber, and its bottom is recessed inwards to form a groove. The lower box body 33 is connected to the upper box body 32, and has a second chamber, a portion of the top of which is located within the groove. This structure effectively prevents X-ray radiation from escaping from the side gap at the top of the second chamber.

[0059] In the embodiment of the invention, the upper housing 32 and the lower housing 33 can be stably connected by hinge 38.

[0060] In one embodiment of the present invention, the four side walls and top wall of the first chamber, as well as the four side walls of the second chamber, are all provided with a protective material layer 34 for shielding X-ray radiation. This can effectively shield X-ray radiation.

[0061] In one embodiment of the present invention, a light source 35 and an air support 36 are provided inside the second chamber. One end of the air support 36 is connected to the bottom of the second chamber, and the other end extends into the second chamber and is connected to the cover of the top wall of the second chamber to provide force support when the cover is opened.

[0062] In one embodiment of the present invention, the bottom of the manual sample box 30 may be provided with feet 39 for supporting the box body. A handle 37 may be provided on the top of the box body for lifting the entire manual sample box 30.

[0063] The energy dispersive X-ray fluorescence spectrometer detection device with intelligent switching between automatic and manual modes according to embodiments of the present invention can realize unattended automatic testing of up to 85 samples, greatly improving manual efficiency; while for some irregularly shaped or single-variety samples, a manual testing mode can be selected, and the manual and automatic modes are integrated into one, and the modes can be automatically switched, realizing intelligent automatic detection and improving detection efficiency.

[0064] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
