[0036] Embodiment 1
[0037] like Figure 1As shown, this embodiment provides an automatic cover opening assembly 100, comprising:

[0042] The driving module 134 is connected to the actuating connecting member 133 among the connecting members 133 , and the driving module 134 drives the actuating connecting member 133 to rotate relative to the base connecting portion 131 or the closing plate 132 .
[0043] The reagent tray 200 is used to hold reagent bottles for testing. Usually, the reagent tray 200 is set in a disc shape so that when the reagent tray 200 rotates around its axis, it will not affect the equipment or structure outside the reagent tray 200. A plurality of reagent positions are arranged circumferentially on the reagent tray 200, and a reagent bottle can be placed in each reagent position.
[0044] The tray cover 110 is disposed on the reagent tray 200, and forms a closed inner cavity with the reagent tray 200. The reagent bottles are isolated from the outside world in the inner cavity. Since the bottle caps of the reagent bottles in the reagent tray 200 are all in an open state, the arrangement of the tray cover 110 is conducive to preventing the reagents in the reagent bottles from being contaminated by impurities or dirt from the outside. The tray cover 110 is provided with a take-in and put-out port 120, which is used to leave a passage for taking out or putting in the reagent bottles. The take-in and put-out port 120 is provided with an opening and closing mechanism 130 for opening and closing the take-in and put-out port 120.
[0045] The opening and closing mechanism 130 includes: a base, a closing plate 132, a connecting member 133 and a driving module 134. The base is arranged on the disk cover 110, and includes two base connecting parts 131. The two base connecting parts 131 are arranged opposite to each other on both sides of the outer edge of the access port 120 to provide positioning for the opening and closing mechanism 130. The closing plate 132 can cover the access port 120, and the projection of the closing plate 132 at the access port 120 completely covers the access port 120. When the closing plate 132 covers the access port 120, the access port 120 is closed. The connecting member 133 connects the closing plate 132 and the base. At least one connecting member 133 is arranged between the closing plate 132 and each base. The connecting members 133 are arranged parallel to each other to synchronously drive the closing plate 132 to move.
[0046] The two ends of the connecting member 133 are respectively hinged to the closing plate 132 and the base connecting part 131, and the connecting member 133 rotates synchronously, wherein the active rotating one is the executing connecting member 133, and the following rotating one is the driven connecting member 133.

[0047] In the present embodiment, since a disc cover 110 is provided on the reagent disc 200, and a take-in and take-out port 120 is provided on the disc cover 110, an opening and closing mechanism 130 is provided at the take-in and take-out port 120. The disc cover 110 and the reagent disc 200 form a closed inner cavity, so that the reagent contained in the reagent bottle in the inner cavity is not easily contaminated by the outside world. The opening and closing mechanism 130 includes a base, a closing plate 132, a connecting member 133 and a driving module 134, and the base enables the opening and closing mechanism 130 to be connected with the disc cover 110, and the connecting member 133 connects the base and the closing plate 132, and drives the closing plate 132 under the drive of the driving module 134 to realize the opening or closing of the take-in and take-out port 120 for the base movement. The opening and closing mechanism 130 is simple to control, and the structure is stable, and it is convenient to control the opening and closing of the take-in and take-out port 120, further reduce the connection between the inner cavity and the outside world, and avoid the reagent from being contaminated.
[0048] Embodiment 2
[0049] like Figure 2 As shown, based on the first embodiment, the driving module 134 includes a rotating shaft 1341 provided at a hinge point between the execution connection member 133 and the base connection portion 131, and the rotating shaft 1341 is fixedly connected to the execution connection member 133; and
[0050] A rotating motor 1342 is connected to the rotating shaft 1341 .
[0051] The driving module 134 includes a rotating motor 1342 and a rotating shaft 1341 connected to the output end of the rotating motor 1342. The rotating shaft 1341 rotates under the drive of the rotating motor 1342. The execution connecting member 133 is fixedly connected to the rotating shaft 1341 and is hinged to the base connecting portion 131 through the rotating shaft 1341. Under the drive of the rotating shaft 1341, the execution connecting member 133 rotates relative to the base connecting portion 131.
[0052] It can be understood that a fixed connection means that no relative movement can occur between the parts after the connection, including detachable fixed connections, such as screw connections, pin connections, snap connections, etc., and non-detachable fixed connections include welding, riveting, gluing, etc., which are not limited here.
[0053] In one embodiment, an output shaft is provided at the output end of the rotating motor 1342 , and the output shaft may be a rotating shaft 1341 .
[0054] Embodiment 3
[0055] like Figure 3 As shown, on the basis of embodiment one, the rotating motor 1342 is connected to the rotating shaft 1341 through a connecting part 135, and the connecting part 135 includes a driving wheel 1351 arranged at the output end of the rotating motor 1342, a driven wheel 1353 sleeved on the rotating shaft 1341, and a belt 1352 connecting the driving wheel 1351 and the driven wheel 1353.
[0056] The connecting part 135 includes a driving wheel 1351, a driven wheel 1353 and a belt 1352. The belt 1352 is sleeved on the driving wheel 1351 and the driven wheel 1353. Under the action of the belt 1352, the driving wheel 1351 drives the driven wheel 1353 to rotate synchronously. The driving wheel 1351 is arranged at the output end of the rotating motor 1342 and is driven to rotate by the rotating motor 1342. The driven wheel 1353 is sleeved on the rotating shaft 1341. The driven wheel 1353 rotates synchronously with the main transmission wheel, and the rotating shaft 1341 rotates synchronously with the driven wheel 1353 sleeved thereon, thereby linking the connecting member 133 to rotate, so as to realize the closing or opening of the access opening 120 by the closing plate 132.
[0057] The setting of the connecting portion 135 can make the connection between the rotating motor 1342 and the rotating shaft 1341 more flexible, and the setting position of the rotating motor 1342 is also more flexible, and can be placed in a suitable position according to specific needs.
[0058] Embodiment 4
[0059] like Figure 2 and Figure 4As shown, based on the first embodiment, a circle of sealed edge 137 is set along the access opening 120, and a sealing step 138 is set on the side of the closing plate 132 facing the access opening 120, and the sealing step 138 is matched with the inner edge of the sealed edge 137.
[0060] The sealing step 138 is matched with the inner edge of the sealed edge 137. When the closing plate 132 covers the access port 120, under the action of the sealing step 138 and the sealed edge 137, the closing plate 132 can better isolate the inner cavity formed by the reagent disk and the disk cover 110 from the outside world, thereby preventing external dirt from contaminating the reagent in the reagent bottle.
[0061] In one embodiment, the sealing edge 137 is connected to the base connection portion 131 as a whole.
[0062] Embodiment 5
[0063] On the basis of the first embodiment, a position sensing device is provided on the edge where the closing plate 132 contacts the access opening 120 .
[0064] The position sensing device is used to sense the closing status of the closing plate 132 and the access port 120. When the closing plate 132 completely closes the access port 120, the position sensing device is triggered and sends a control signal to stop the driving module 134 from working, thereby preventing the closing plate 132 from excessive movement, crushing the disk cover 110 or causing damage to the components of the driving module 134.
[0065] The position sensing device can be a contact sensing device, which is touched when the closing plate 132 is closed in place at the access port 120; the position sensing device can also be a light sensing device, which is blocked when the closing plate 132 is closed in place at the access port 120.
[0066] The specific installation position of the position sensing device needs to be determined according to the closed state of the closing plate 132 and the access port 120. If the closing plate 132 covers the access port 120, the position sensing device is arranged on the side of the closing plate 132 facing the access port 120; if the closing plate 132 is embedded in the access port 120, the position sensing device is arranged on the side of the closing plate 132.
[0067] Embodiment 6
[0068] On the basis of the first embodiment, a position sensing device is provided at the position where the edge of the access opening 120 contacts the closing plate 132 .
[0069] The position sensing device in this embodiment is equivalent to the implementation method and beneficial effects of the position sensing device in Implementation 5, and will not be described in detail here.
[0070] Embodiment 7
[0071] like Figure 2 and Figure 3 As shown, on the basis of the first embodiment, at least one position sensing device 136 is provided on the movement path of the connecting member 133 .
[0072] Since the closing plate 132 is driven to move by the connecting member 133, the moving position of the connecting member 133 determines the moving position of the closing plate 132. At least the position sensing device 136 is arranged on the moving path of the connecting member 133. When the connecting member 133 reaches the position where the position sensing device 136 is located, the position sensing device 136 is triggered, and the position of the connecting member 133 is determined, that is, the position of the closing plate 132 is determined.
[0073] In one embodiment, two position sensing devices 136 are provided, and the two position sensing devices 136 are respectively provided at two ends of the movement path of the connecting member 133 .
[0074] The two position sensing devices 136 are respectively arranged at the two ends of the movement path of the connecting member 133. When the connecting member 133 moves to one end of the movement path, the closing plate 132 closes the access opening 120. When the connecting member 133 moves to the other end of the movement path, the access opening 120 is opened. When the two position sensing devices 136 are triggered, the driving module 134 stops working to prevent the closing plate 132 from excessively moving and crushing the disk cover 110 or causing damage to the components of the driving module 134.
[0075] The position sensing device 136 may be a contact sensing device or a light sensing device, which is not limited here.
[0076] In one embodiment, the position sensing device 136 includes a blocking piece disposed on any connecting member 133 and an optical coupler disposed on the moving path of the connecting member 133 .
[0077] Since the connecting member 133 moves synchronously, the baffle is set on any connecting member 133, and the optical coupler is set on the movement path of the connecting member 133. When the baffle follows the movement of the connecting member 133 to block the optical coupler, the optical coupler sends a trigger signal.
