Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluorescence immunoassay equipment technology, specifically to a reaction cup transfer device. Background Technology
[0002] Currently, most automated fluorescence immunoassay analyzers use a rotary disc structure for their reaction devices, with reaction cups arranged on a rotating disc and reagents and samples added in conjunction with a sample dispensing mechanism.
[0003] When reaction cups are of the same shape, the size of the turntable is determined by the number of reaction cups. Clinically, the more samples that can be tested simultaneously, the better, as this can shorten the time to get results per unit. However, too many reaction cups result in an excessively large turntable diameter, which in turn leads to an excessively large analyzer size, affecting the layout of the laboratory.
[0004] Therefore, a common approach is to arrange multiple reaction discs to increase the number of reaction cups, allowing different reaction stages to occur on different discs. To maintain temperature, the reaction cups typically only have a small hole at the top to accommodate a suction needle, making it impossible to remove them from above the disc. This creates a new challenge in transferring these reaction cups between multiple reaction discs. Utility Model Content
[0005] To solve the above problems, this utility model provides a reaction cup transfer device that can stably push and transfer the reaction cup. It has a simple structure, low cost, and convenient operation and control.
[0006] The technical solution adopted by this utility model is to provide a reaction cup transfer device, including a mounting frame, an incubation tray and a cleaning tray rotatably mounted on the mounting frame, an incubation support and a cleaning support arranged in a circular array at the lower ends of the incubation tray and the cleaning tray, respectively, and a finger-shifting mechanism mounted on the mounting frame and located below the incubation tray and the cleaning tray. The finger-shifting mechanism includes a fixed frame, a flip motor mounted on the fixed frame, a flip shaft rotatably mounted on the fixed frame, a flip sleeve fitted on the flip shaft, a finger plate fixed on the flip sleeve, a translation motor mounted on one side of the fixed frame, a driven pulley mounted on the other side of the fixed frame, a translation belt mounted on the drive end of the translation motor and the driven pulley, and a translation seat connected to the translation belt. The flip motor is driven by the flip shaft, and the flip motor drives the flip shaft to rotate, causing the flip sleeve and the finger plate to rotate synchronously. The translation motor is parallel to the flip shaft, and the translation motor drives the translation belt to move in a circular motion and cause the translation seat to translate. The translation seat is provided with a mounting hole, and the flip sleeve is rotatably mounted in the mounting hole. The upper end of the finger plate is provided with a cup groove.
[0007] The flipping shaft has a multi-faceted prism structure, and the flipping sleeve has a cylindrical structure and is adapted to the flipping shaft.
[0008] The incubation tray includes an outer ring rotatably mounted on a mounting frame, external teeth on the outer periphery of the outer ring, an external motor mounted on the mounting frame and located on one side of the outer ring, an external gear on the drive end of the external motor, an inner ring rotatably mounted on the mounting frame and located inside the outer ring, internal teeth on the inner periphery of the inner ring, an inner motor mounted on the mounting frame and located inside the inner ring, and an internal gear on the drive end of the inner motor. The external gear meshes with the external teeth on the outer periphery of the outer ring, and the internal gear meshes with the internal teeth on the inner periphery of the inner ring. The incubation support bases are arranged in a circular array at the lower ends of the outer ring and the inner ring, respectively.
[0009] The incubation tray and the cleaning tray have the same structure, and the incubation support and the cleaning support have the same structure.
[0010] The incubation support includes a connecting block, a guide block fixed to the lower end of the connecting block, and overlapping blocks respectively arranged on both sides of the guide block. The overlapping blocks are symmetrically arranged and extend horizontally to both sides of the guide block.
[0011] The end faces on both sides of the guide block are symmetrical inclined surfaces.
[0012] There are two cup slots.
[0013] The beneficial effects of this utility model are that it provides a reaction cup transfer device. Both the incubation tray and the cleaning tray adopt a double-ring structure, which can significantly increase the number of reaction cups that can be stored without increasing the volume. The reaction cups on the incubation tray can be quickly and smoothly transferred to the cleaning tray via a finger mechanism. This design has a simple structure, low cost, and convenient operation and control. It can realize the automated transfer of reaction cups, and the finger mechanism transfers the reaction cups quickly, accurately, and smoothly. Attached Figure Description

Detailed Implementation
[0022] like Figure 1-7 As shown, this utility model provides a reaction cup transfer device, including a mounting frame 1, an incubation tray 2 and a cleaning tray 3 rotatably mounted on the mounting frame 1, and incubation support seats 4 and cleaning support seats 5 arranged in a circular array at the lower ends of the incubation tray 2 and the cleaning tray 3, respectively. It also includes a finger-shifting mechanism mounted on the mounting frame 1 and located below the incubation tray 2 and the cleaning tray 3. The finger-shifting mechanism includes a fixed frame 6, a flipping motor 7 mounted on the fixed frame 6, a flipping shaft 8 rotatably mounted on the fixed frame 6, a flipping sleeve 9 fitted onto the flipping shaft 8, a finger plate 10 fixed to the flipping sleeve 9, and a translation motor 11 located on one side of the fixed frame 6. The following components are provided: a driven pulley 12 on the other side of the fixed frame 6; a translation belt 13 on the drive end of the translation motor 11 and the driven pulley 12; and a translation seat 14 connected to the translation belt 13. The flip motor 7 is connected to the flip shaft 8. The flip motor 7 drives the flip shaft 8 to rotate, causing the flip sleeve 9 and the finger plate 10 to rotate synchronously. The translation motor 11 is parallel to the flip shaft 8. The translation motor 11 drives the translation belt 13 to move in a ring and causes the translation seat 14 to move. The translation seat 14 is provided with a mounting hole. The flip sleeve 9 is rotatably installed in the mounting hole. The upper end of the finger plate 10 is provided with a cup groove 15.
[0023] The reaction vessel has an outwardly folded rim at the top. The reaction vessel rests between two adjacent incubation supports 4 or cleaning supports 5, using the rim as a support. Figure 7 The incubation tray 2 and the cleaning tray 3 are rotatable. When the reaction cup placed between the incubation tray 4 corresponds to the position between the adjacent cleaning tray 5, the finger mechanism can push the reaction cup from the incubation tray 4 to the cleaning tray 5, thus completing the transfer of the reaction cup between the incubation tray 2 and the cleaning tray 3.
[0024] In use, the incubation tray 2 and the cleaning tray 3 rotate until the reaction cups placed between the incubation stands 4 align with the positions of the adjacent cleaning stands 5. Then, the rotation motor 7 drives the rotation shaft 8 to rotate, causing the finger plates 10 on the rotation sleeve 9 to flip, placing the finger plates 10 in a flat position to avoid the reaction cups. The finger plates then move horizontally below the incubation tray 2 and the cleaning tray 3. The horizontal movement belt 13 is annular, with one end fitted onto the driven pulley 12, which is located below one end of the rotation shaft 8. The other end of the horizontal movement belt 13 is fitted onto the drive end of the horizontal movement motor 11, which is located on the rotation shaft 8. At the other end below, the translation motor 11 drives the translation belt 13 to move in a ring, which in turn moves the translation seat 14. After the cup groove 15 at the upper end of the finger plate 10 aligns with the reaction cup at the lower end of the incubation tray 2, the finger plate 10 swings upward under the drive of the flip motor 7, changing from a flat state to an upright state. The lower end of the reaction cup then enters the cup groove 15. The cup groove 15 at the upper end of the finger plate 10 is adapted to the middle and lower part of the reaction cup and abuts against the bottom of the cup groove 15, keeping the horizontal height of the reaction cup unchanged. The translation motor 11 drives the finger plate 10 to move horizontally, moving the reaction cup horizontally between the cleaning and placement seats 5, thus completing the transfer of the reaction cup.
[0025] Since the translation seat 14 and the flip sleeve 9 are connected, the flip sleeve 9 and the finger plate 10 translate synchronously. The flip sleeve 9 is fitted on the flip shaft 8 and is circumferentially limited, so the flip sleeve 9 can slide on the flip shaft 8 and rotate synchronously with the flip shaft 8. The flip sleeve 9 and the translation seat 14 are rotatably connected and axially limited, so the translation seat 14 will not hinder the rotation of the flip sleeve 9 and can drive the flip sleeve 9 to translate synchronously.
[0026] This design has a simple structure and low cost. It can stably and accurately push the reaction cup to transfer it between the incubation tray and the washing tray. The operation and control are simple and convenient.
[0027] like Figure 2-3 As shown, the flip shaft 8 has a polygonal prism structure, and the flip sleeve 9 has a cylindrical structure and is adapted to the flip shaft 8. This allows the flip shaft 8 to drive the flip sleeve 9 more stably and synchronously, without hindering the sliding of the flip sleeve 9 on the flip shaft 8.
[0028] like Figure 1 and Figure 6As shown, the incubation tray 2 includes an outer ring 16 rotatably mounted on the mounting frame 1, an outer tooth 17 disposed on the outer periphery of the outer ring 16, an outer motor 18 disposed on the mounting frame 1 and located on one side of the outer ring 16, an outer gear 19 disposed on the drive end of the outer motor 18, an inner ring 20 rotatably mounted on the mounting frame 1 and located inside the outer ring 16, an inner tooth 21 disposed on the inner periphery of the inner ring 20, an inner motor 22 disposed on the mounting frame 1 and located inside the inner ring 20, and an inner gear 23 disposed on the drive end of the inner motor 22. The outer gear 19 meshes with the outer tooth 17 on the outer periphery of the outer ring 16, and the inner gear 23 meshes with the inner tooth 21 on the inner periphery of the inner ring 20. The incubation support 4 is arranged in a circular array at the lower ends of the outer ring 16 and the inner ring 20, respectively.
[0029] An external motor 18 drives an external gear 19 to rotate. The external teeth 21 on the outer ring 16 mesh with the external gear. The rotation of the external gear 19 drives the outer ring 16 to rotate. An internal motor 22 drives an internal gear 23 to rotate. The internal teeth 21 on the inner circumference of the inner ring 20 mesh with the internal gear 23. The rotation of the internal gear 23 drives the inner ring 20 to rotate. This allows the outer ring 16 and the inner ring 20 to rotate independently without interfering with each other.
[0030] In this design, the incubation tray 2 adopts a double-ring structure with an outer ring 16 and an inner ring 20, which can rotate independently. The lower ends of both the outer ring 16 and the inner ring 20 can be used to place reaction cups, which can greatly increase the number of reaction cups that can be stored without increasing the volume. It has the characteristics of compact structure and high space utilization.
[0031] like Figure 1 and Figure 6 As shown, the incubation tray 2 and the cleaning tray 3 have the same structure, and the incubation support 4 and the cleaning support 5 have the same structure. Using the same structure makes production assembly more convenient and reduces production costs.
[0032] like Figure 5 As shown, the incubation support 4 includes a connecting block 24, a guide block 25 fixed to the lower end of the connecting block 24, and overlapping blocks 26 respectively arranged on both sides of the guide block 25. The overlapping blocks 26 are symmetrically arranged and extend horizontally to both sides of the guide block 25.
[0033] The upper end of the connecting block 24 is fixed to the lower end of the incubation tray 2, that is, the lower end of the outer ring 16 or the inner ring 20. The cup edges on both sides of the reaction cup are respectively placed on the overlapping blocks 26 of the two adjacent incubation support seats 4. This design has a simplified structure, low production cost, and high strength.
[0034] like Figure 5 As shown, the end faces on both sides of the guide block 25 are symmetrical inclined surfaces 27.
[0035] The inclined surfaces 27 on both sides of the guide block 25 make the guide block 25 thinner at the front and thicker at the back. The thinner end of the guide block 25 faces the direction of the reaction cup, making it easier for the reaction cup to enter. The inclined surfaces 27 can guide the entering reaction cup, allowing the reaction cup to enter the precise position.
[0036] like Figure 4 As shown, two cups are provided in the cup trough 15. The cup trough 15 can move the reaction cups at the lower ends of the outer ring 16 and the inner ring 20 simultaneously. The reaction cup at the lower end of the outer ring 16 of the incubation tray 2 enters the cleaning tray, while the reaction cup at the lower end of the inner ring 20 enters the outer ring 16. The transfer of the two reaction cups can be completed with a single translation of the finger plate 10, which is very efficient.
