Description

Technical Field

[0001] This invention belongs to the field of detection technology, specifically relating to a test tube moving and covering device. Background Technology

[0002] Soil environmental monitoring refers to determining the environmental quality (or pollution level) and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we usually refer to it, generally includes technical aspects such as sampling site selection, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation.

[0003] Atomic flame absorption spectrometry (hereinafter referred to as spectrometer) can detect a variety of elements. It is now used in soil testing. Typically, test tubes in a test tube rack contain the mother liquor or diluted mother liquor to be tested, and then the test tubes are transported to the spectrometer for analysis. However, the analysis time is relatively long, and the untested mother liquor in the test tube rack may become contaminated, affecting the test results.

[0004] For example, the fully automated sample introduction system for an energy dispersive X-ray spectrometer disclosed in patent publication number CN215449066U, and the fully automated sample introduction system for a spectral analysis instrument disclosed in patent publication number CN213689654U, both have no covering device for the sample in the sample tray, which may result in the sample being contaminated by the outside world. Summary of the Invention

[0005] The purpose of this invention is to provide a test tube moving and covering device that can cover the test tubes in the test tube rack to prevent the samples to be tested inside the test tubes from being contaminated.

The test tube rack is located inside the shielding ring belt. The shielding ring belt is provided with a shielding groove. The X-axis connecting bracket is fixed to the shielding ring belt. The first X-axis driving device drives the shielding ring belt to rotate, so that the shielding groove moves above the test tube to be measured, so that the test tube to be measured is in an unshielded state.

[0015] Furthermore, the shielding ring includes a ring body and a fixing buckle, the fixing buckle is fixed to both ends of the ring body, and the shielding through groove is provided on the fixing buckle.

[0016] Furthermore, there are two first X-axis drive devices, and an X-axis connecting crossbar is fixed between the two X-axis connecting brackets. The X-axis connecting crossbar is located above the shielding member, and the first Y-axis drive device is fixed on the X-axis connecting crossbar.

[0017] Furthermore, the first X-axis drive device is fixed below the support plate, and the support plate is provided with an X-axis through slot for the X-axis connecting bracket to pass through.

[0018] Furthermore, the support plate is provided with a support protrusion, the test tube rack is placed on the support protrusion, the support protrusion is provided with a support through groove, and the lower side of the shielding ring passes through the support through groove.

[0019] Furthermore, it also includes a sample delivery and cleaning device, which comprises:

[0020] A rotating device, which is fixed on the supporting plate;

[0021] A rotating support is mounted on the rotating device, which drives the rotating support to rotate. The rotating support is provided with a plurality of lifting grooves, which are evenly distributed around the axis of the rotating support.

[0022] A plurality of mounting supports are provided, each corresponding to a lifting slide. Each mounting support includes a lifting rod and a support body.

[0024] Furthermore, the support lifting device is configured as a lifting cylinder, which is fixed to the lower side of the support plate and positioned below the suction pipe. The piston rod of the lifting cylinder drives the mounting support located below the suction pipe to move up and down.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) When a test tube on the test tube rack needs to be tested, the first X-axis drive device drives the shielding device to move, so that the test tube to be tested is in an unshielded state. At this time, the first Y-axis drive device drives the gripping device to move in the Y-axis direction. Then the first Z-axis drive device drives the gripping device to move along the Z-axis direction, so that the gripping device can grip the test tube to be tested and move it to the testing instrument for testing. After the gripping is completed, the first X-axis drive device drives the shielding device to move and continue to cover the test tube on the test tube rack, so as to avoid the sample to be tested in the test tube being contaminated by the outside when no testing is being performed.

[0027] (2) The first X-axis drive device can move the blocking part and drive the gripping device to move, making the entire device structure simpler and more compact.

[0028] (3) The rotating support integrates a test tube holder and a cleaning water tank. By simply rotating the rotating support, the test tube or cleaning water tank can be moved to the bottom of the spectrometer's suction tube. Then, the support lifting device drives the test tube or cleaning water tank to be inserted into the suction tube. The structure is very compact and saves time and effort.

[0046] Please see Figures 1-13 The present invention provides a test tube moving and covering device.

[0047] like Figures 1-9 As shown, a test tube moving and covering device 100 includes:

[0048] Support tablet 1;

[0049] Test tube rack 4, test tube rack 4 is placed on support plate 1, and test tubes are installed on test tube rack 4;

[0050] A shielding component 102 is disposed above the test tube rack 4;

[0051] The first X-axis drive device 113 is fixed on the support plate 1. An X-axis connecting bracket 114 is installed on the first X-axis drive device 113. A blocking member 102 is connected to the X-axis connecting bracket 114. The first X-axis drive device 113 is used to drive the blocking member 102 to move, so that the blocking member 102 can block or unblock the test tubes on the test tube rack 4.

[0052] The first Y-axis drive device 115 is fixed on the X-axis connecting bracket 114.

[0053] The first Z-axis drive device 116 is mounted on the first Y-axis drive device 115;

[0054] The gripping device 117 is mounted on the first Z-axis drive device 116.

[0055] When a test tube on the test tube rack 4 needs to be tested, the first X-axis drive device 113 drives the shielding member 102 to move, thereby placing the test tube to be tested in an unshielded state. At this time, the first Y-axis drive device 115 drives the gripping device 117 to move along the Y-axis direction, and then the first Z-axis drive device 116 drives the gripping device 117 to move along the Z-axis direction, thereby causing the gripping device 117 to grip the test tube to be tested and move it to the testing instrument 6 for testing. After the gripping is completed, the first X-axis drive device 113 drives the shielding member 102 to move, continuing to cover the test tube on the test tube rack 4, thereby preventing the sample to be tested in the test tube from being contaminated by the outside when no testing is being performed.

[0056] The first X-axis drive device 113 can move the blocking part 102 and drive the gripping device 117 to move, making the entire device structure simpler and more compact.

[0057] The following is one method of using the shielding element 102, such as... Figure 2 and Figure 5 As shown, the shielding component 102 includes a shielding ring belt 103, a first shielding frame, and a second shielding frame. The first shielding frame includes a first shielding support 104, a first support upper rotating roller 105 and a first support lower rotating roller 106 rotatably connected to the first shielding support 104. The second shielding frame includes a second shielding support 107, a second support upper rotating roller 108 and a second support lower rotating roller 109 rotatably connected to the second shielding support 107. The first shielding frame and the second shielding frame are respectively arranged on both sides of the test tube rack 4. The shielding ring belt 103 is sleeved on the outside of the first support upper rotating roller 105, the second support upper rotating roller 108, the second support lower rotating roller 109, and the first support lower rotating roller 106. The test tube rack 4 is located inside the shielding ring belt 103. The shielding ring belt 103 is provided with a shielding through groove 110. The X-axis connecting bracket 114 is fixed to the shielding ring belt 103.

[0058] When a sample in a test tube needs to be tested, the first X-axis drive device 113 drives the shielding ring belt 103 to rotate, causing the shielding slot 110 to move above the test tube to be measured, so that the test tube to be measured is in an unshielded state. After the test tube to be measured is removed, the shielding drive unit drives the shielding member 102 to move, removing the shielding slot 110, and the shielding member 102 continues to cover the test tubes on the test tube rack 4.

[0059] like Figure 7 As shown, the shielding ring 103 includes a ring body 111 and a fixing buckle 112. The fixing buckle 112 is fixed to both ends of the ring body 111, and the shielding through groove 110 is provided on the fixing buckle 112. The fixing buckle 112 serves to fix the two ends of the ring body 111 together, which facilitates the installation of the ring body 111.

[0060] like Figure 8As shown, two first X-axis drive devices 113 are provided. An X-axis connecting crossbar 101 is fixed between the two X-axis connecting brackets 114. The X-axis connecting crossbar 101 is located above the shielding member 102. The fixing buckle 112 is fixed together with the X-axis connecting crossbar 101. The first Y-axis drive device 115 is fixed on the X-axis connecting crossbar 101. The first X-axis drive device 113 is fixed below the support plate 1. The support plate 1 is provided with an X-axis through slot 5 for the X-axis connecting brackets 114 to pass through. Using two first X-axis drive devices 113 can increase the stability of movement.

[0061] like Figure 5 As shown, the support plate 1 is provided with a support protrusion 2, the test tube rack 4 is placed on the support protrusion 2, the support protrusion 2 is provided with a support through groove 3, the lower side of the shielding ring 103 passes through the support through groove 3, so that the shielding ring 103 can pass under the test tube rack 4 without being affected.

[0062] like Figures 10-13 As shown, the test tube moving and covering device also includes a sample delivery and cleaning device 200, which includes:

[0063] Rotating device 201, which is fixed on the supporting plate 1;

[0064] Rotary support 202 is mounted on rotating device 201. Rotating device 201 is used to drive rotating support 202 to rotate. Rotary support 202 is provided with a plurality of lifting slide grooves 203. The plurality of lifting slide grooves 203 are evenly distributed around the axis of rotating support 202.

[0065] Several mounting supports 204 are provided, each corresponding to a lifting slide 203. Each mounting support 204 includes a lifting rod 205 and a support body 206. The support body 206 is fixedly connected to one end of the lifting rod 205 that passes through the lifting slide 203. A cleaning water tank 207 is installed on one of the support bodies 206, and test tube holders 208 are installed on the other support bodies 206. Test tubes to be tested are installed on the test tube holders 208.

[0066] The support lifting device 209 is used to drive the mounting support 204 to move up and down. After the mounting support 204 is raised by the support lifting device 209, the liquid suction tube 7 of the testing instrument 6 is inserted into the test tube to be tested or the cleaning water tank 207.

[0067] The support lifting device 209 is configured as a lifting cylinder, which is fixed on the lower side of the support plate 1. The lifting cylinder is located below the suction pipe 7. The piston rod of the lifting cylinder drives the mounting support 204 located below the suction pipe 7 to move up and down.

[0068] The rotating device 201 is a hollow rotating platform. Since the hollow rotating platform is an existing device, its specific structure will not be described in detail.

[0069] The gripping device 117 places the test tube to be tested on the test tube holder 208. The rotating device 201 drives the rotating support 202 to rotate, so that the test tube to be tested moves below the liquid suction tube 7 of the spectrometer. The support lifting device 209 drives the mounting support 204 to move upward, so that the liquid suction tube 7 of the spectrometer is connected to the test tube to be tested. The detection instrument 6 (spectrometer) detects the liquid to be tested in the test tube. After the detection is completed, the support lifting device 209 drives the mounting support 204 to move downward, and the test tube to be tested leaves the liquid suction tube 7 of the spectrometer.

[0070] When it is necessary to clean the testing instrument 6 (spectrometer), rotate the rotating support 202 to move the cleaning water tank 207 below the liquid suction tube 7 of the spectrometer. The support lifting device 209 drives the mounting support 204 to move upward, so that the liquid suction tube 7 of the testing instrument 6 (spectrometer) can be inserted into the cleaning water tank 207 for cleaning. After cleaning, the support lifting device 209 drives the cleaning water tank 207 away from the liquid suction tube 7.

[0071] The rotating support 202 integrates a test tube holder 208 and a cleaning water tank 207. By simply rotating the rotating support 202, the test tube holder 208 or the cleaning water tank 207 can be moved to the bottom of the spectrometer's suction tube 7. Then, the support lifting device 209 drives the test tube or the cleaning water tank 207 to be inserted into the suction tube 7. The structure is very compact and saves time and effort.
