Therefore, it should not be construed as a limitation to the present utility model.

[0033] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0034] Referring to Figures 1 to 6 , an embodiment of the present utility model provides a push - plate type upper - cup mechanism, which includes a hopper 100 and a conveying assembly 200. The hopper 100 has an inner cavity for storing a large number of reaction cups 300 in the inner cavity of the hopper 100. The upper end of the hopper 100 is usually open, facilitating the loading of the reaction cups 300 into the inner cavity, and they can be replenished at any time during operation. As Figure 7 shown, the reaction cups 300 used in a chemiluminescence immunoassay analyzer are similar to test tubes. A protruding support ring 310 is provided on the outer wall of the reaction cup 300, and the support ring 310 is located at one end close to the opening of the reaction cup 300. The hopper 100 has a first side wall 110, and an outlet groove 111 and an outlet 112 are provided on the first side wall 110. The outlet groove 111 is vertically arranged, and the outlet 112 is located at the upper end of the outlet groove 111. The width of the outlet groove 111 is slightly larger than the length of the reaction cup 300, so that the horizontally placed reaction cup 300 can move in the outlet groove 111. The conveying assembly 200 is connected to the hopper 100. The conveying assembly 200 includes a cup - pushing block 210 and a power device 220. The cup - pushing block 210 is arranged in the outlet groove 111, and the power device 220 can drive the cup - pushing block 210 to lift and lower. When the cup - pushing block 210 descends to the lowest position, a plurality of reaction cups 300 slide above the cup - pushing block 210, and then the cup - pushing block 210 rises to push a horizontally placed reaction cup 300 upward, and the reaction cup 300 rises to the outlet 112 and is output.

[0035] The push-plate cup loading mechanism proposed in the utility model adopts a conveying component 200 with a simple structure, and adopts a cup pushing block 210 to replace a chain and a cup scooping block, which is convenient for debugging and disassembly and maintenance. In addition, the cup pushing block 210 pushes the reaction cup 300 to rise, eliminating the problems of cup jamming and cup dropping, thereby improving work efficiency.

[0036] Reference Figures 2 to 4 In some embodiments of the first aspect of the utility model, the outer wall of the hopper 100 is connected to a guide member 120, and the upper end surface of the guide member 120 is set to be an inclined surface 121, and the inclined surface 121 is set to be inclined downward in a direction away from the hopper 100, and the inclined surface 121 is adjacent to the discharge port 112. When the cup pushing block 210 rises to the highest position, the upper end of the cup pushing block 210 is higher than the inclined surface 121, and the reaction cup 300 pushed by the cup pushing block 210 is higher than the inclined surface 121, and the reaction cup 300 automatically rolls down from the inclined surface 121 through the discharge port 112, and then is transported to the equipment of the next process.

[0037] Reference Figure 3 and Figure 4 Considering that the reaction cup 300 will contact the hopper 100 during the rising process, if the reaction cup 300 rolls, the friction resistance can be reduced. Therefore, the reaction cup 300 needs to be able to roll relative to the cup pushing block 210. A roller 211 is arranged at the upper end of the cup pushing block 210. The roller 211 is arranged horizontally and can rotate. The roller 211 contacts the reaction cup 300, and the reaction cup 300 can rotate freely. During the rising process, the reaction cup 300 can roll relative to the hopper 100 to reduce friction resistance, which helps to eliminate the problem of cup jamming and improve the conveying efficiency.

[0038] It can be understood that a bracket is provided at the upper end of the cup pushing block 210 to install a horizontal rotating shaft, and the roller 211 is installed on the rotating shaft through a bearing to achieve the free rolling of the roller 211. The two ends of the rotating shaft can be installed on the bracket with screws for easy disassembly and assembly to meet the needs of replacing the roller 211 after wear, which is convenient for operation.

[0039] It can be understood that the cup pushing block 210 pushes one reaction cup 300 upward each time. In order to prevent the reaction cup 300 from falling, the diameter of the roller 211 is designed to be larger than the diameter of the reaction cup 300, and a groove is formed between the roller 211 and the bottom wall of the discharge trough 111, so that the reaction cup 300 falls into the groove. During the rising process, the roller 211 will not fall out of the groove, which helps to eliminate the problem of the cup falling.

[0040] Reference Figure 2 and Figure 5, in some embodiments of the first aspect of the present utility model, the discharge chute 111 penetrates from the first side wall 110 to the outer wall of the hopper 100, and the guiding member 120 closes the lower part of the discharge chute 111. The unclosed part of the upper part of the discharge chute 111 is the discharge port 112. That is, the guiding member 120 serves as the bottom wall of the discharge chute 111, and the pushing cup block 210 is adjacent to the guiding member 120. The pushing cup block 210 can be in contact with the guiding member 120, or there can be a tiny gap between the pushing cup block 210 and the guiding member 120. The pushing cup block 210 pushes the reaction cup 300 to a position higher than the guiding member 120, and then the guiding member 120 rolls down to the inclined surface 121.

[0041] In addition, it can also be that the discharge chute 111 is a groove on the first side wall 110. The thickness between the bottom wall of the discharge chute 111 and the outer wall of the hopper 100 is relatively small, for example, the set thickness is 1 mm. The bottom wall of the discharge chute 111 is set as a smooth plane, which is beneficial for the pushing cup block 210 to push the reaction cup 300 to rise with less frictional resistance.

[0042] Referring to Figures 1 to 3 , in some embodiments of the first aspect of the present utility model, the push plate type cup loading mechanism further includes an alignment component 400. The alignment component 400 is connected to the hopper 100 and / or the guiding member 120. The function of the alignment component 400 is to change the reaction cup 300 from a horizontal state to a vertical state for use in the next process. Therefore, the alignment component 400 is provided with an alignment groove. The alignment groove is located at the lower edge of the inclined surface 121. The width of the alignment groove is greater than the diameter of the reaction cup 300 and less than the diameter of the support ring 310 on the outer wall of the reaction cup 300. When the reaction cup 300 rolls down from the inclined surface 121 to the alignment groove, under the action of gravity, the reaction cup 300 will fall into the alignment groove, and the support ring 310 will rest on the side wall of the alignment groove, making the reaction cup 300 become a vertical state.

[0043] It can be understood that the alignment component 400 is further provided with a cup pushing block 410. The cup pushing block 410 is located above the alignment groove and can move along the length direction of the alignment groove to push the reaction cup 300 in the alignment groove. The cup pushing block 410 is connected to a power source, which can be a belt driven by a motor or an electric push rod, as long as it can drive the cup pushing block 410 to move. The cup pushing block 410 is used to push the reaction cup 300 to move in the alignment groove. Finally, the reaction cup 300 enters the cup guiding tube 420 at the outlet of the alignment groove. A turntable 430 is arranged below the cup guiding tube 420. The turntable 430 has a plurality of through holes evenly distributed in the circumferential direction. The diameter of the through hole is larger than the diameter of the reaction cup 300 and smaller than the diameter of the support ring 310. The vertical reaction cup 300 can fall into the through hole of the turntable 430 and be carried on the turntable 430. The alignment component 400 is further provided with two first sensors 440. The two first sensors 440 are located on one side of the outlet of the alignment groove and are arranged above and below the alignment groove. The two first sensors 440 are used to detect whether there is a reaction cup 300 in the alignment groove. If not, the conveying component 200 is started to convey a reaction cup 300 to the alignment groove. Then the turntable 430 rotates once to move a through hole without a loaded reaction cup 300 directly below the cup guiding tube 420. Then the reaction cup 300 in the alignment groove is sent into the cup guiding tube 420 through the cup pushing block 410, and the reaction cup 300 falls along the cup guiding tube 420 into the through hole of the reaction cup 300. The two first sensors 440 respectively detect both ends of the reaction cup 300, and the detection result is more accurate, avoiding affecting the detection accuracy due to the reaction cup 300 being stuck when rolling down from the inclined surface 121.

[0044] It can be understood that a second sensor 450 and a third sensor 460 are further arranged on one side of the turntable 430. The second sensor 450 and the third sensor 460 respectively detect the cup body and the cup mouth of the reaction cup 300 loaded on the turntable 430 to confirm whether there is a reaction cup 300 on the turntable 430 before proceeding to the next process, such as other mechanisms transferring the reaction cup 300 on the turntable 430 away.

[0045] Refer to Figures 3 to 5, in some embodiments of the first aspect of the present utility model, the power device 220 includes a first motor 221, a driving wheel 222, a driven wheel 223 and a belt 224. An installation plate 130 is provided at the lower end of the hopper 100. The first motor 221 is fixed to the installation plate 130. The driving wheel 222 is installed on the output shaft of the first motor 221. The driven wheel 223 is rotatably connected to the installation plate 130. The belt 224 is connected between the driving wheel 222 and the driven wheel 223. A belt seat 212 is connected to the lower end of the pushing cup block 210, and the belt seat 212 is fixedly connected to the belt 224. When the motor 221 drives the driving wheel 222 to rotate, the belt 224 can be driven to move. The driven wheel 223 is located below the driving wheel 221, so that two sections of the belt 224 are in a vertical state. The belt 224 drives the belt seat 212 and the pushing cup block 210 to rise or fall. By the forward rotation and reverse rotation of the first motor 221, the pushing cup block 210 can be made to repeatedly lift and lower.

[0046] Of course, the power device 220 can also be of other structures, such as an electric push rod, a motor cooperating with a lead screw nut pair, etc., all of which can achieve the purpose of driving the pushing cup block 210.

[0047] It can be understood that a slide rail 131 is provided on the side of the installation plate 130. The slide rail 131 is vertically arranged. The pushing cup block 210 is slidably connected to the slide rail 131. It can be that the pushing cup block 210 is connected to a slider 213, and the slider 213 is slidably connected to the slide rail 131, or it can be that the pushing cup block 210 is provided with a sliding portion cooperating with the slide rail 131 and is directly installed on the slide rail 131. The slide rail 131 is used to guide the movement of the pushing cup block 210, so as to prompt the pushing cup block 210 to accurately push the reaction cup 300 to the discharge port 112, and can also prevent the pushing cup block 210 from shifting, improving the use stability. Positioning blocks are arranged at both ends of the slide rail 131 to limit the stroke of the pushing cup block 210 and prevent the pushing cup block 210 from coming out.

[0048] Refer to 3 to Figure 6, in some embodiments of the first aspect of the present utility model, a stirring cup plate 230 is provided on the side surface of the cup pushing block 210. The stirring cup plate 230 is arranged vertically and perpendicular to the cup pushing block 210. The stirring cup plate 230 rises and falls with the cup pushing block 210, and uses the stirring cup plate 230 to stir a plurality of reaction cups 300 in the inner cavity of the hopper 100, preventing problems such as bridging and jamming of the reaction cups 300, and helping the cup pushing block 210 to push one reaction cup 300 each time. The upper end of the stirring cup plate 230 is inclined, which helps the stirring cup plate 230 to push away a plurality of reaction cups 300. The height of the stirring cup plate 230 is lower than that of the cup pushing block 210. After the cup pushing block 210 pushes away one reaction cup 300, it stirs a plurality of reaction cups 300. A through groove is provided at the lower end of the hopper 100 to cooperate with the stirring cup plate 230 and the cup pushing block 210, so that the stirring cup plate 230 and the cup pushing block 210 can enter the inner cavity of the hopper 100. To facilitate the installation of the stirring cup plate 230, a support 214 is installed on the side surface of the cup pushing block 210. The support 214 is provided with a slot, and the stirring cup plate 230 is inserted into the slot. The stirring cup plate 230 can be fixed by an interference fit method, which simplifies the structure and is convenient for disassembly and assembly.

[0049] An embodiment of the second aspect of the present utility model provides a chemiluminescence immunoassay analyzer, which includes a push plate type cup loading mechanism of the first aspect embodiment. The push plate type cup loading mechanism includes a hopper 100 and a conveying assembly 200. The hopper 100 has a first side wall 110, and a discharge slot 111 and a discharge port 112 are provided on the first side wall 110. The discharge slot 111 is arranged vertically, and the discharge port 112 is located at the upper end of the discharge slot 111. The width of the discharge slot 111 is slightly larger than the length of the reaction cup 300, so that the horizontally placed reaction cup 300 can move in the discharge slot 111; the conveying assembly 200 is connected to the hopper 100. The conveying assembly 200 includes a cup pushing block 210 and a power device 220. The cup pushing block 210 is arranged in the discharge slot 111, and the power device 220 can drive the cup pushing block 210 to rise and fall. When the cup pushing block 210 descends to the lowest position, a plurality of reaction cups 300 slide above the cup pushing block 210, and then the cup pushing block 210 rises to push a horizontally placed reaction cup 300 upward, and the reaction cup 300 rises to the discharge port 112 and is output. The structure of the conveying assembly 200 is simple. The cup pushing block 210 is used instead of a chain and a cup fishing block, which is convenient for debugging and disassembly and maintenance. Moreover, the cup pushing block 210 pushes the reaction cup 300 to rise, eliminating problems such as cup jamming and cup dropping, and improving work efficiency.

[0050] In addition, the chemiluminescence immunoassay analyzer includes all the technical solutions of the push plate type cup loading mechanism and has all the technical effects of the push plate type cup loading mechanism, which will not be elaborated here.
