Each rotating installation site is rotationally provided with one rotating seat 102, each rotating seat 102 is fixedly provided with one rotating idler 103, a plurality of rotating idlers 103 are connected in sequence, and after series connection, a rotating motor 104 and any one rotating idler 103 are driven to realize the synchronous transmission of a plurality of rotating idlers 103.

[0042] The clamping jaw module 200 is arranged in one-to-one correspondence with the rotating installation position, and the clamping jaw module 200 is arranged on the bottom of the rotating module 100. Each clamping jaw module 200 comprises a clamping jaw seat 201, a clamping jaw assembly 202 and a control rod 203. The clamping jaw seat 201 is arranged coaxially with the rotating idler 103, and the clamping jaw seat 201 is fixedly connected with the rotating seat 102. Only one rotating motor 104 can realize the synchronous rotation of the plurality of clamping jaw modules 200.

[0043] In order to control the opening and closing of the clamping jaw assembly 202, the opening and closing module 300 is further arranged on the clamping jaw module 200. The opening and closing module 300 comprises a second linkage block 301, an opening and closing transmission member 302 and an opening and closing motor 303.

The opening and closing transmission member 302 is in transmission connection with the second linkage block 301. The driving end of the opening and closing motor 303 is fixedly connected with the opening and closing transmission member 302, so as to drive the opening and closing transmission member 302 to rotate, so that the second linkage block 301 reciprocates in the vertical direction, thereby controlling the relative sliding of the plurality of control rods 203 and the corresponding clamping jaw seats 201, changing the opening state or the closing state of the clamping jaw assembly 202. The opening and closing of the plurality of clamping jaw modules 200 can be realized by one opening and closing motor 303.

[0044] In the embodiment, the rotating motor 104 and the opening and closing motor 303 of the multi-station switch cover device are fixedly arranged on the linkage fixing plate 105, and the overall rotation movement of the clamping jaw module 200 and the opening and closing movement of the clamping jaw module 200 do not affect each other. Only two power sources of the rotating motor 104 and the opening and closing motor 303 are needed on the overall mechanical structure of the multi-station switch cover device, so as to respectively realize the overall rotation movement and the opening and closing movement of the plurality of clamping jaw modules 200. When the plurality of test tubes are opened and closed, the multi-station switch cover device does not need to move in the horizontal direction, effectively reducing the movement mechanism, further improving the work efficiency, and at the same time, the structure is simple and compact, the overall volume is small, and the manufacturing cost is low.

[0045] Specifically, Figure 3As shown in FIG. 1, the jaw module 200 and the rotating idler 103 are fixed on the rotating seat 102, the jaw module 200 can rotate with the rotating idler 103, and the rotating seat 102 has a through hole in the middle, and the control rod 203 can pass through the middle of the rotating seat 102. The jaw assembly 202 includes two sets of connecting rods 2020 arranged oppositely, each set of connecting rods 2020 includes a first driven rod 2021, a second driven rod 2022 and a third driven rod 2023, the jaw seat 201, the third driven rod 2023, the second driven rod 2022 and the first driven rod 2021 are sequentially rotationally connected, and the first driven rod 2021, the second driven rod 2022 and the third driven rod 2023 of the connecting rod 2020 form a four-bar linkage structure with the control rod 203, the first driven rod 2021 is provided with a gear at an end away from the second driven rod 2022, and the control rod 203 is provided with two symmetrical racks at an end away from the second linkage block 301 on opposite sides, and the racks and the gear are one-to-one corresponding and meshing transmission.

[0046] The third driven rod 2023 and the first driven rod 2021 are the same length and relatively parallel, the second driven rod 2022 is always vertically arranged and kept parallel to the control rod 203 during movement, and the second driven rod 2022 is provided with a jaw head 2024 at an end away from the third driven rod 2023. As shown in Figure 4 and Figure 5 As shown in FIG. 1, when the control rod 203 moves vertically downward, the first driven rod 2021 swings upward at an end away from the gear until the first driven rod 2021 is in a horizontal state, the second driven rod 2022 and the third driven rod 2023 rotate, and the two jaw heads 2024 relatively move away to be parallel and open; when the second linkage block 301 moves upward to drive the control rod 203 to move vertically upward, the meshing gear is also driven to rotate by the rack, the first driven rod 2021 swings downward at an end away from the gear, and the two jaw heads 2024 relatively move close to gradually close. The opening and closing of the jaw assembly 202 in the jaw module 200 are parallel movements, the jaw assembly 202 is parallel and opened and closed, so that it can be suitable for clamping test tube covers of different diameters, and for some sample tubes or reagent tubes which are generally general consumables, the multi-station cover switching device can be used without special customization of sample tubes or reagent tubes and other consumables, and has strong universality and adaptability, further saving the working cost and expanding the application range of the multi-station cover switching device.

[0047] In the embodiment, the opening and closing module 300 further comprises bearings 304, which are arranged between the control rods 203 and the second linkage blocks 301, and the bearings 304 are arranged one-to-one with the control rods 203. The outer rings of the bearings 304 are embedded in the second linkage blocks 301, and the inner rings of the bearings 304 are sleeved on the control rods 203. The inner and outer rings of the bearings 304 are coaxial and are connected in relative rotation, so that the rotating movement of the jaw modules 200 and the opening and closing movement of the jaw modules 200 are independent of each other and do not affect each other.

[0048] Further, the opening and closing module 300 further comprises elastic members 305, which are arranged in the vertical direction. One end of each elastic member 305 is connected with the inner ring of a bearing 304, and the other end of the elastic member 305 is connected with a control rod 203. The control rod 203 of the jaw module 200 is connected with the second linkage block 301 through the elastic member 305, so that the jaw module 200 and the second linkage block 301 can move up and down relative to each other.

[0049] When the jaw assembly 202 closes and clamps the cap of the test tube, the second linkage block 301 continues to move upward, and the control rod 203 can only slightly move to clamp the cap of the test tube by the jaw assembly 202, and at the same time, the elastic member 305 is compressed. By controlling the degree of upward movement of the second linkage block 301, the size of parallel closing and the clamping force of the jaw assembly 202 can be controlled, so that the caps of test tubes with different diameters can be clamped. Due to the existence of the elastic member 305, a plurality of same jaw modules 200 can compensate for the differences in clamping different test tube caps by the elastic member 305, and there is no unified requirement for the test tube specifications for simultaneous opening and closing operations. The multi-station cap opening and closing device has strong compatibility and adaptability, and further expands the application range. The elastic member 305 can be a compression spring or other elastic body.

[0050] As shown in detail in Figure 2 The opening and closing module 300 further comprises first linear guides 306, which are fixed on the linkage fixed plate 105 in the vertical direction. The second linkage blocks 301 are slidably arranged in the first linear guides 306, and the auxiliary opening and closing transmission members 302 jointly limit the movement of the second linkage blocks 301, thereby prolonging the service life of the multi-station cap opening and closing device.

[0051] Exemplarily, the rotating module 100 further comprises a plurality of synchronous belts 106, each of the rotating idlers 103 is sleeved in one of the synchronous belts 106 in pairs with the adjacent rotating idlers 103 to drive, that is, each of the rotating idlers 103 has one rotating idler 103 on each of the adjacent sides, the rotating idler 103 has two synchronous belts 106 arranged alternately thereon, and the two synchronous belts 106 are further sleeved in the two rotating idlers 103 adjacent to the rotating idler 103. Alternatively, only one large synchronous belt can be used to drive all the rotating idlers 103 together, and simultaneously rotate the plurality of jaw modules 200.

[0052] In the embodiment, the driving end of the rotating motor 104 is driven by the synchronous belt 106 to drive any one of the rotating idlers 103, so that the rotating seat 102 and the jaw module 200 rotate; the driving end of the opening and closing motor 303 can also be driven by the synchronous belt 106 to drive the opening and closing transmission member 302, so as to control the up-down movement of the second linkage block 301. The installation position of the rotating motor 104 or the opening and closing motor 303 can be reasonably changed by the synchronous belt, so as to avoid interference with other structures and save the occupied space of the multi-station switch cover device.

[0053] Specifically, as shown in Figure 6 The multi-station switch cover device further comprises a lifting module 400, the lifting module 400 comprises a mounting plate 401, a lifting motor 403 and a lifting transmission member 402, the mounting plate 401 is used for fixing the multi-station switch cover device to the in-vitro diagnostic equipment; the lifting motor 403 is fixed on the mounting plate 401, the lifting transmission member 402 is in transmission connection with the linkage fixing plate 105, the driving end of the lifting motor 403 is fixedly connected with the lifting transmission member 402, and the lifting motor 403 can drive the lifting transmission member 402 to rotate to make the linkage fixing plate 105 reciprocate in the vertical direction, so as to realize the up-down movement of the jaw module 200. The linkage fixing plate 105 is installed on the mounting plate 401 through an adapter block, the lifting motor 403 controls the lifting transmission member 402 to rotate through the synchronous belt, and then controls the adapter block and the linkage fixing plate 105 to move up and down, so as to realize the up-down movement of the jaw module 200.

[0054] Exemplarily, the lifting transmission member 402 and the opening and closing transmission member 302 can be screw rod assemblies or other transmission assemblies.

[0055] Similarly, the lifting module 400 also comprises a second linear guide rail fixed on the mounting plate 401 along the vertical direction, and the linkage fixed plate 105 is slidably arranged on the second linear guide rail, and the auxiliary lifting transmission member 402 jointly limits the movement of the linkage fixed plate 105, thereby prolonging the service life of the multi-station switch cover device. Alternatively, guide shafts 404 are arranged on both sides of the lifting transmission rod, and three adapter blocks are arranged on the linkage fixed plate 105 and correspond to the lifting transmission rod and the guide shafts 404, so that the linkage fixed plate 105 can be slidably limited along the vertical direction, and the movement of the multi-station switch cover device is more stable.

[0056] The utility model discloses still a kind of multi-station switch cover device's use method, applied to above-mentioned multi-station switch cover device, the use method of multi-station switch cover device includes:

[0057] Step one, start opening and closing motor 303, so that opening and closing transmission member 302 drives second linkage block 301 vertically downward movement, while control rod 203 drives jaw assembly 202 to open;

[0058] Step two, jaw assembly 202 is one-to-one corresponding with test tube cover, and jaw assembly 202 is moved from initial height to the same height with test tube cover;Control opening and closing motor 303 reverses so that opening and closing transmission member 302 drives second linkage block 301 vertically upward movement, control rod 203 drives jaw assembly 202 to close until jaw assembly 202 clamps test tube cover, and opening and closing motor 303 is closed;

[0059] Step three, start rotating motor 104, drive rotary idler 103 rotates along the direction of opening cover and drives rotary seat 102 and jaw module 200 to rotate, while first linkage block 101 is moved upwards until test tube cover and test tube are separated, and rotating motor 104 is closed;

[0062] Step six, continue to move first linkage block 101 downwards, while starting rotating motor 104, drive rotary idler 103 rotates along the direction of closing cover and drives rotary seat 102 and jaw module 200 to rotate until test tube cover and test tube are screwed tightly, and rotating motor 104 is closed;

In order to clamp the test tube cover more stably, continue to drive the second linkage block 301 to move vertically upward by a certain distance until the jaw assembly 202 clamps the test tube cover, and turn off the opening and closing motor 303.
