[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0036] The technical solutions disclosed in the embodiments of the present application will be described in detail below with reference to the drawings.
[0037] Please refer to Figures 1 to 12 The sample detection device disclosed in the embodiments of the present application comprises a base 100, a sample pressing mechanism 200, a transmission mechanism 300 and a sample detection main body 400.
[0038] The base 100 can provide a mounting basis for some components of the sample detection device. The base 100 is provided with a first avoiding structure 110, which can be an avoiding through hole or an avoiding gap penetrating through the base 100.
[0039] The sample pressing mechanism 200 comprises a sample box 210, a pressing block 220 and a pressing mechanism 230. The pressing mechanism 230 comprises a top head 231 which is distributed opposite to the first avoiding structure 110 and is movable relative to the base 100. The top head 231 can pass through the first avoiding structure 110 and is lifted between a first position and a second position. The first position is higher than the second position. The power for lifting the top head 231 between the first position and the second position can be provided by a first driving member 232 of the pressing mechanism 230. The first position is above the base 100, and the second position is below the base 100.
[0040] When the top head 231 is lifted to the first position, the top head 231 presses the sample box 210 and the pressing block 220, so that the sample in the sample space surrounded by the sample box 210 and the pressing block 220 is pressed and formed.
[0041] When the top head 231 is lowered to the second position, the sample box 210 is separated from the pressing block 220 by following the top head 231 to be lowered. The sample box 210 is supported on the transmission mechanism 300 and can be conveyed to a detection position by the transmission mechanism 300.
[0042] The sample detection main body 400 is arranged on the base 100 and is used for detecting the sample pressed and formed in the sample box 210 at the detection position.
[0043] In the embodiment of the present application, the sample detection device is provided with the structure including the base 100, the sample pressing mechanism 200, the conveying mechanism 300 and the sample detection main body 400. The base 100 is provided with the first avoiding structure 110. The sample pressing mechanism 200 is provided with the sample box 210, the pressing block 220 and the pressing mechanism 230. The pressing mechanism 230 is provided with the punch 231 which is distributed opposite to the first avoiding structure 110 and is movable relative to the base 100. The punch 231 can pass through the first avoiding structure 110 and is lifted between the first position and the second position. The first position is higher than the second position. When the punch 231 is lifted to the first position, the punch 231 presses the sample box 210 and the pressing block 220, so that the sample in the sample space surrounded by the sample box 210 and the pressing block 220 is pressed and formed. When the punch 231 is lowered to the second position, the sample box 210 is separated from the pressing block 220 by following the punch 231 to be lowered. The sample box 210 is supported on the conveying mechanism 300 and can be conveyed to the detection position by the conveying mechanism 300. Then, the sample in the sample box 210 which is pressed and formed is detected by the sample detection main body 400. Since the sample detection device integrates the functions of sample pressing, sample conveying and sample detection, the conveying device and the sample pressing device do not need to be separately provided, so that the operation of the sample detection device can be simplified.
[0044] The sample box 210 can be placed on the punch 231 by the mechanical hand or directly placed on the punch 231 by the human hand. However, the sample box 210 is prone to deviation during the placement, which is not conducive to the pressing of the sample. In order to accurately place the sample box 210 on the punch 231, an optional embodiment of the sample detection device can further include the sample feeding guiding mechanism 500 which can be arranged on the base 100. The sample feeding guiding mechanism 500 can include the guiding boss 510 which can surround the third avoiding structure 511 with a gap. The third avoiding structure 511 is opposite to the first avoiding structure 110. The punch 231 can have the third position which is between the first position and the second position.
[0045] When the punch 231 is in the third position, the sample box 210 can enter from the gap and move to the position of the punch 231 under the guiding cooperation of the outer wall of the sample box 210 and the inner wall of the third avoiding structure 511 which surrounds the third avoiding structure 511, and can be supported by the punch 231.
[0046] The sample detection device disclosed by the embodiment of the present application sets the sample injection guide mechanism 500, which comprises the guide boss 510, and the guide boss 510 encloses the third avoiding structure 511 with a gap, so that when the punch head 231 is in the third position, the sample box 210 can be used to enter from the gap, and under the guide cooperation of the outer wall of the sample box 210 and the inner wall of the third avoiding structure 511, the sample box 210 is moved to the position of the punch head 231 and can be supported by the punch head 231, so that the sample box 210 can be accurately placed on the punch head 231.
[0047] In a specific embodiment, the pressing block 220 can comprise the pressing ring 221 and the pressing block body 222, the pressing ring 221 can be sleeved at the opening of the sample box 210 and detachably connected with the sample box 210, and the pressing ring 221 can have the lap joint part 2211 which lap-joints with the guide boss 510. When the punch head 231 rises to the first position, the pressing block body 222 can extend into the opening of the pressing ring 221 which is away from the sample box 210, and the punch head 231 can press the sample box 210 and the pressing block body 222 tightly, so that the sample in the sample space enclosed by the sample box 210, the pressing ring 221 and the pressing block body 222 is pressed into shape. When the punch head 231 descends to the second position, the sample box 210 can be separated from the pressing block body 222 by following the punch head 231 to descend, and the pressing ring 221 can lap-joint at the edge of the guide boss 510 through the lap joint part 2211, so that the pressing ring 221 is indirectly lap-jointed at the edge of the first avoiding structure 110, and the sample box 210 can be supported on the transmission mechanism 300, so as to realize the separation of the pressing ring 221 and the sample box 210.
[0048] Of course, in another embodiment, the pressing ring 221 can be separated from the sample box 210 by the mechanical hand, and the present application does not limit the specific structure for realizing the separation of the pressing ring 221 and the sample box 210.
[0049] The sample detection device disclosed by the embodiment of the present application sets the pressing block 220 as the structure comprising the pressing ring 221 and the pressing block body 222, so that the pressing ring 221 can be sleeved at the opening of the sample box 210 and detachably connected with the sample box 210, so as to enclose a larger space by the pressing ring 221 and the sample box 210, so that the pressing ring 221 can assist the sample box 210 to load the sample. When the punch head 231 descends to the second position, the sample box 210 can be separated from the pressing block body 222 by following the punch head 231 to descend, and the pressing ring 221 can lap-joint at the edge of the guide boss 510 through the lap joint part 2211, so that the pressing ring 221 can be avoided to be transported together with the sample box 210 to the detection position by the transmission mechanism 300.
[0050] In order to keep the sample box 210 stable during the lifting process between the base 100 and the top head 231, the sample feeding guide mechanism 500 can further include a guide vertical wall 520, which can be arranged at the edge of the guide boss 510 and extend along the lifting direction of the top head 231. During the switching process of the top head 231 driving the sample box 210 between the first position and the third position, the guide vertical wall 520 can guide the pressing block 220 in the lifting direction of the top head 231, so as to limit the movement of the sample box 210 in the direction perpendicular to the lifting direction, thereby keeping the sample box 210 stable during the lifting process between the base 100 and the top head 231.
[0051] When the top head 231 is in the third position, the sample box 210 can enter from the gap, and the sample box 210 can be moved to the position of the top head 231 under the guide cooperation between the outer wall of the sample box 210 and the inner wall of the guide boss 510 surrounding the third avoiding structure 511, and the guide cooperation between the guide vertical wall 520 and the pressing block 220, and can be supported by the top head 231, so that the guide vertical wall 520 and the pressing block 220 can guide the cooperation during the process that the sample box 210 enters from the gap, so that the sample box 210 can be more accurately moved to the position of the top head 231.
[0052] In order to facilitate the sample box 210 to be placed on the top head 231 more easily, the sample feeding guide mechanism 500 can further include a feeding door plate 530, which can be provided with a sample feeding port 531 opposite to the gap.
[0053] The sample detection device disclosed in the embodiment of the present application can make the feeding door plate 530 provided with the sample feeding port 531 opposite to the gap, so that the sample box 210 can enter from the sample feeding port 531 of the feeding door plate 530, thereby facilitating the sample box 210 to be placed on the top head 231 more easily.
[0054] In an optional embodiment, the sample detection device can further include a sample pressing beam 600 arranged on the base 100. When the top head 231 is in the third position, the pressing block body 222, the pressing ring 221 and the sample box 210 can be sequentially detachably connected, and the pressing block body 222 can extend into the opening of the pressing ring 221 away from the sample box 210. When the top head 231 is lifted to the first position, the pressing block body 222 can abut against the sample pressing beam 600, and the top head 231 can press the sample box 210 and the pressing block body 222 tightly, so that the sample in the sample space surrounded by the sample box 210, the pressing ring 221 and the pressing block body 222 is pressed into a shape.
[0055] It should be noted that, in the case that the punch 231 is in the third position, the pressing block body 222, the pressing ring 221 and the sample box 210 are detachably connected, at this time, the sample space surrounded by the sample box 210, the pressing ring 221 and the pressing block body 222, but no pressure is applied. In the case that the punch 231 is raised to the first position, the pressing block 220 is in contact with the pressing beam 600, and the punch 231 presses the sample box 210 and the pressing block body 222, so that the sample in the sample space surrounded by the sample box 210, the pressing ring 221 and the pressing block body 222 is pressed into shape.
[0056] The sample detection device disclosed in the embodiments of the present application is provided with the pressing beam 600, so that in the case that the punch 231 is raised to the first position, the pressing block body 222 can be in contact with the pressing beam 600, so that the punch 231 can press the sample box 210 and the pressing block body 222, so that the sample in the sample space surrounded by the sample box 210, the pressing ring 221 and the pressing block body 222 can be pressed into shape.
[0057] The pressing of the sample can be according to a certain volume ratio, or can be according to a specific pressure value. In the case of pressing according to a specific pressure value, the sample detection device can further include a pressure sensor 700, which can be arranged on the pressing beam 600, and in the case that the punch 231 is raised to the first position, the pressure sensor 700 can be pressed between the pressing block body 222 and the pressing beam 600. The pressure sensor 700 can be used to detect the pressing force between the sample box 210 and the pressing block body 222, so that when the pressing force between the sample box 210 and the pressing block body 222 reaches a preset pressure, the sample pressing is completed, and the punch 231 can drive the sample box 210 to descend.
[0058] The sample detection device disclosed in the embodiments of the present application is provided with the pressure sensor 700 on the pressing beam 600, so that in the case that the punch 231 is raised to the first position, the pressure sensor 700 can be arranged between the pressing block body 222 and the pressing beam 600 to detect the pressing force between the sample box 210 and the pressing block body 222, so that the sample can be pressed according to a specific pressure value.
[0059] In order to avoid excessive pressing force, optionally, when the pressing force is greater than a first threshold value, the sample detection device can throw an alarm information, so as to facilitate the operator to intervene in time.
[0060] When the powder sample or the granular sample is pressed, if the sample is only filled in the sample accommodating groove 211 of the sample box 210, the thickness or the volume of the sample after being pressed may be small due to the small amount of the sample, which is not conducive to the detection of the sample. In order to obtain a sample with a large thickness or a large volume after being pressed, optionally, the sample box 210 can be provided with the sample accommodating groove 211, the pressing block 220 can include the pressing ring 221 and the pressing block body 222, and the pressing ring 221 can include the pressing ring body 2212. The pressing ring body 2212 can have a first hole section a and a second hole section b, the inner diameter of the first hole section a can be smaller than the inner diameter of the second hole section b, and the connection between the first hole section a and the second hole section b forms a first limiting mesa c. When the first hole section a and the second hole section b are circular holes, the inner diameter of the first hole section a and the inner diameter of the second hole section b can be the diameter of the hole of the first hole section a and the second hole section b. The inner diameter of the first hole section a can be equal to the inner diameter of the sample accommodating groove 211, and the pressing ring body 2212 can be used to be sleeved on the sample box 210 through the second hole section b, and the slot end surface of the sample accommodating groove 211 is in limiting contact with the first limiting mesa c, so that the pressing ring body 2212 is sleeved on the sample box 210.
[0061] The inner diameter of the first hole section a is equal to the inner diameter of the sample accommodating groove 211, and the first hole section a is equivalent to an extension of the side wall of the sample accommodating groove 211, so that the first hole section a and the sample accommodating groove 211 jointly form a deeper groove, which can accommodate more samples. The pressing block body 222 is used to extend into the opening of the first hole section a, so that the pressing block body 222, the first hole section a and the sample accommodating groove 211 form a sample accommodating space.
[0062] Specifically, when the punch 231 rises to the first position, the pressing block body 222 can extend into the opening of the first hole section a, the pressing block body 222, the first hole section a and the sample accommodating groove 211 can form a sample accommodating space, and the punch 231 can press the sample box 210 and the pressing block body 222 tightly, so that the sample in the sample space is pressed and formed. When the punch 231 descends to the second position, the sample box 210 can be separated from the pressing block body 222 and the pressing ring 221 by following the punch 231 to descend, the sample box 210 can be supported on the transmission mechanism 300 and can be conveyed to the detection position by the transmission mechanism 300.
[0063] The sample detection device disclosed in the embodiments of the present application can obtain a sample with a large thickness or a large volume after being pressed by setting the pressing block 220 to include the pressing ring 221 and the pressing block body 222, and the pressing ring 221 includes the pressing ring body 2212, so that the pressing ring body 2212 can be sleeved on the sample box 210 through the second hole section b, and the first hole section a and the sample accommodating groove 211 can jointly form a deeper groove, which can accommodate more samples.
[0064] In order to separate the pressing ring 221 from the sample box 210 during the process that the punch 231 is lowered from the first position to the second position, the pressing ring 221 can further comprise a lap portion 2211, which can be arranged on the outer wall of the pressing ring body 2212 and extend away from the pressing ring body 2212. The lap portion 2211 can be used to lap with the edge of the first avoiding structure 110 during the process that the punch 231 is lowered from the first position to the second position, so as to separate the pressing ring 221 from the sample box 210. It should be noted that the sample box 210 can be separated from the pressing ring body 2212 under the action of gravity when the pressing ring body 2212 is sleeved on the sample box 210. Specifically, the lap portion 2211 can be a continuous annular structure, or a protruding structure arranged at intervals, or other structures, and the specific structure of the lap portion 2211 is not limited in the embodiment of the present application.
[0065] The sample detection device disclosed in the embodiment of the present application can separate the sample box 210 from the pressing ring 221 more conveniently by arranging the lap portion 2211 on the outer wall of the pressing ring body 2212, so that the lap portion 2211 can lap with the edge of the first avoiding structure 110 during the process that the punch 231 is lowered from the first position to the second position, and the sample box 210 is separated from the pressing ring 221 by following the punch 231 to continue to descend.
[0066] In an optional embodiment, when the pressing ring body 2212 is sleeved on the sample box 210 and contains a sample, the pressing block body 222 can be inserted into the opening of the first hole section a, so that the pressing block body 222, the pressing ring 221 and the sample box 210 move to the first position together, and the pressing block body 222 can be pressed tightly with a component (for example, the pressing sample beam 600 described below) of the sample detection device for abutting against the pressing block body 222, so that the sample in the sample space is pressed and formed. In order to facilitate the separation of the pressing block body 222 from the sample box 210, the first end portion of the pressing block body 222 can have a flange 2221, and the second end portion of the pressing block body 222 can be used to insert into the opening of the first hole section a. The first end portion of the pressing block body 222 is opposite to the second end portion of the pressing block body 222, and the flange 2221 can be used to lap with the edge of the opening of the first hole section a during the process that the punch 231 is lowered from the first position to the second position, so as to separate the pressing block body 222 from the sample box 210.
[0067] The sample detection device disclosed by the embodiment of the present application sets the flange 2221 on the sample box 210, so that in the process of the top head 231 from the first position to the second position, the flange 2221 can be lapped with the orifice edge of the first hole section a, so that the pressing block body 222 is lapped at the orifice edge of the first hole section a, and the sample box 210 is separated from the pressing ring 221 by following the top head 231 to continue to drop, so that the separation of the sample box 210 and the pressing block body 222 is more convenient.
[0068] Specifically, the sample detection device includes the sample feeding guide mechanism 500, the sample feeding guide mechanism 500 is arranged on the base 100, and the sample feeding guide mechanism 500 includes the guide boss 510, the guide boss 510 surrounds the third avoiding structure 511 with a gap, and in the case that the third avoiding structure 511 is opposite to the first avoiding structure 110, the lapping part 2211 can be used to lap with the edge of the guide boss 510 in the process of the top head 231 from the first position to the second position, so that the lapping part 2211 is indirectly lapped at the edge of the first avoiding structure 110 through the guide boss 510.
[0069] An optional embodiment, the transmission mechanism 300 can include the transmission body 310, the transmission body 310 can be provided with the second avoiding structure 311, in the case that the first avoiding structure 110 and the second avoiding structure 311 are opposite, the top head 231 can pass through the first avoiding structure 110 and the second avoiding structure 311 to rise and fall between the first position and the second position. In the case that the top head 231 drops to the second position, the sample box 210 can follow the top head 231 to drop and separate from the pressing block 220, the sample box 210 can be lapped at the edge of the second avoiding structure 311, and can be transported to the detection position by the transmission body 310.
[0070] The sample detection device disclosed by the embodiment of the present application sets the second avoiding structure 311 on the transmission body 310, so that in the case that the top head 231 drops to the second position, the sample box 210 can follow the top head 231 to drop and separate from the pressing block 220, the sample box 210 can be lapped at the edge of the second avoiding structure 311, so that the sample box 210 is supported on the transmission body, so that the structure of supporting the sample box 210 on the transmission mechanism 300 is simple.
[0071] It should be noted that the second avoiding structure 311 can be an avoiding through hole or an avoiding gap penetrating through the transmission body 310, and the embodiment of the present application does not limit the specific structure of the second avoiding structure 311.
[0072] In an embodiment, the sample box 210 can also be placed on the transmission body 310 by the mechanical hand.
