Description

Technical Field

[0001] The utility model relates to the technical field of high-speed biochemical analyzers, and particularly relates to a reaction cup recycling device for a chemiluminescence analyzer. Background Art

[0002] A chemiluminescence analyzer is an instrument used to detect the chemiluminescence phenomenon in chemical reactions. It quantitatively analyzes the content of substances based on the principle of photon release in chemical reactions. This analysis technology is widely used in the detection and analysis of various antigens, haptens, antibodies, hormones, enzymes, etc. in biomedicine, and also has extensive applications in environmental monitoring and food safety.

[0003] Reaction cups are indispensable consumables when using a chemiluminescence analyzer, and all chemical reactions require the use of reaction cups. Reaction cups are used to hold reagents, magnetic particles, etc. During the operation of the instrument, the reaction cups are grabbed by the reagent arm and moved between various modules. After the sample detection is completed, they are clamped by the robotic arm and placed into a waste bucket for recycling and unified treatment to prevent contamination.

[0004] In current instruments, after the reaction cup recycling waste bucket is full, the waste bucket needs to be taken out, the reaction cups inside are emptied, and then it is put back into the instrument. During this process, the instrument equipment needs to be repeatedly started and stopped. Therefore, in the prior art, taking out the waste bucket will delay the operation of the instrument. Since the interval for the robotic arm to discard reaction cups is short, only a few seconds, but the time to empty the waste bucket far exceeds the time for the robotic arm to discard reaction cups. Therefore, there is an urgent need for a device that can replace the waste bucket without stopping the instrument and without affecting the recycling of reaction cups.

[0005] Therefore, the prior art urgently needs to be solved. Content of the Utility Model

[0030] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0031] Please refer to Figures 1-3, a reaction cup recycling device for a chemiluminescence analyzer, comprising a lower tube 1, a first fixing block 2, a second fixing block 3, a first coupling shaft 4, a second coupling shaft 5, a first waste bucket 7 and a second waste bucket 9. The lower tube 1 has a hollow through-hole for the reaction cup to pass through. The first fixing block 2 is fixedly connected to one side of the bottom of the lower tube 1, and the second fixing block 3 is fixedly connected to the other side of the bottom of the lower tube 1. The first fixing block 2 and the second fixing block 3 are preferably welded. The lower surfaces of the first fixing block 2 and the second fixing block 3 are flush with the lower outlet surface of the lower tube 1. The first coupling shaft 4 passes through the center of the first fixing block 2 and is fixedly connected to the first fixing block 2. Springs 6 are respectively arranged at the two ends of the first coupling shaft 4. One end of the spring 6 is fixedly connected to the end of the first coupling shaft 4, and the other end of the spring 6 is fixedly connected to the side surface of the first waste bucket 7. The second coupling shaft 5 passes through the center of the second fixing block 3 and is fixedly connected to the second fixing block 3. The end of the second coupling shaft 5 is rotatably connected to the first waste bucket 7. The second waste bucket 9 is arranged below the first waste bucket 7. In this embodiment, the lower tube 1 is connected to the bottom plate of the chemiluminescence analyzer. The volume of the second waste bucket 9 is larger than that of the first waste bucket 7.

[0032] Preferably, it further comprises a bending plate 8. One end of the bending plate 8 is fixedly connected to the bottom of the first waste bucket 7, and the other end of the bending plate 8 is a free end for abutting against the second waste bucket 9. During use, under the thrust of the second waste bucket 9, the bending plate 8 causes the first waste bucket 7 to be in an inclined state.

[0033] Preferably, it further comprises a slide rail piece 10 and a slide rail 11. The slide rail piece 10 is fixedly arranged on both sides below the second waste bucket 9 and is located near the first waste bucket 7. The slide rail 11 is arranged on both sides below the second waste bucket 9. A chute 1101 is formed on the side surface of the slide rail 11. The slide rail piece 10 is adapted to and slidably connected with the chute 1101. The chute 1101 plays a role of limiting and guiding the slide rail piece 10. The slide rail piece 10 slides in the chute 1101 to limit the second waste liquid bucket 9 to move along a horizontal straight line and ensure that it will not move obliquely.

[0034] Preferably, it further comprises a limit baffle 12 for restricting the movement of the second waste bucket 9. The limit baffle 12 is arranged at the front end of the second waste bucket 9, and the limit baffle 12 is detachably connected to the second waste bucket 9. The limit baffle 12 cooperates with the bending plate 8 to further restrict the movement of the second waste bucket 9.

[0035] Please refer to Figure 6, preferably, the limit baffle 12 includes a first inclined support plate 122, a main support plate 121, and a second inclined support plate 123. The first inclined support plate 122, the main support plate 121, and the second inclined support plate 123 are integrally formed. The first inclined support plate 122 and the main support plate 121 are arranged at an obtuse angle, and the second inclined support plate 123 and the main support plate 121 are arranged at an obtuse angle. When the second waste bin 9 is fixed by the limit baffle 12, the main support plate 121 is in fit connection with the front end face of the second waste bin 9. The first inclined support plate 122 facilitates pushing up the limit baffle 12 by hand.

[0036] Please refer to Figure 4 , preferably, a clamping groove 1102 is provided at the end of the slide rail 11, and the shape of the clamping groove 1102 is adapted to the second inclined support plate 123. The clamping groove 1102 and the second inclined support plate 123 make the second waste bin 9 firmly fixed.

[0037] Please refer to Figure 5 , preferably, a first positioning hole 901 is provided on the front end face of the second waste bin 9, and a second positioning hole 1201 corresponding to the first positioning hole 901 is provided on the main support plate 121. The first positioning hole 901 and the second positioning hole 1201 are positioned by a positioning pin (not shown in the figure). Preferably, the first positioning hole 901 is a round hole, and the second positioning hole 1201 is an oval long hole. The second positioning hole 1201 can facilitate the adjustment and positioning between the first positioning hole 901 and the second positioning hole 1201.

[0038] Preferably, the first waste bin 7 is in a bucket-shaped structure, and the front end face of the first waste bin 7 and its bottom surface are arranged at an obtuse angle. With such a setting, when the second waste bin 9 is installed in place, the first waste bin 7 remains in an inclined state, facilitating the reaction cup to fall into the second waste bin 9.

[0039] Preferably, the first waste bin 7 and the second waste bin 9 are respectively made of sheet metal or aluminum alloy. This greatly reduces the manufacturing cost of the device and also makes the device more reliable and convenient for popularization and use.

[0040] When the reaction cup recycling device for the chemiluminescence analyzer is in use, the spring 6 is in a stretched state. At this time, after the robotic arm of the chemiluminescence analyzer grabs the reaction cup, it is dropped into the through hole of the lower tube 1 and falls into the first waste bin 7 below. At this time, the first waste bin 7 is in an inclined state. Since the first waste bin 7 is in a bucket-shaped structure, in the inclined state, the first waste bin 7 plays a guiding role. The reaction cups falling into the first waste bin 7 automatically slide down to the second waste bin 9 below due to their own gravity and will not accumulate in the first waste bin 7. After the reaction cups in the second waste bin 9 are full, the staff lifts the first inclined support plate 122 upward, and the second waste bin 9 is pulled out along the slide rail 11. At this time, after the second waste bin 9 is pulled out, the spring 6 resets, and the upper first waste bin 7 automatically moves upward under the reset action of the spring 6 and returns to the horizontal position, facing the through hole outlet of the lower tube 1. After this, the reaction cups will fall into the first waste bin 7 below. At this time, the first waste bin 7 is a bucket-shaped waste bin, which functions as a temporary storage for reaction cups. The reaction cups will be stored in the first waste bin 7 until the second waste bin 9 returns. Such a design enables, on the one hand, not to stop the instrument after taking out the second waste bin 9, without delaying the operation of the instrument, and on the other hand, to continue to recycle and collect reaction cups through the first waste bin 7, overall improving the working continuity and efficiency of the instrument equipment.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
