[0038] Referring to Figures 1 to 6 As shown, according to the embodiment of the application, a hole plate turnover device is provided, comprising:

[0039] A fixed plate 1, which has a first side upward hole plate placing state and a first side downward hole plate using state, a rectangular placing area (not labeled in the figure) is formed on the first side for placing the hole plate 100;

[0040] A rotating shaft 2, which is connected with the fixed plate 1 to drive the fixed plate 1 to rotate around the rotating axis of the rotating shaft 2 to switch between the hole plate placing state and the hole plate using state, it can be understood that the first end of the fixed plate 1 is connected to the rotating shaft 2, and the second end of the rotating shaft 2 is connected with a rotating drive motor to drive the fixed plate 1 to rotate when the rotating drive motor rotates;

[0041] A right-angle stop structure (not labeled in the figure) is arranged at the outer edges of two mutually adjacent right-angle sides of the rectangular placement area, i.e., is arranged at the outer side area corresponding to the second corner of the hole plate 100;

[0042] The hole plate clamping member 4 is rotationally connected with the fixed plate 1, and has a clamping end 41 at the outer edge of the intersection area of the other two mutually adjacent right-angle sides of the rectangular placement area. During the process of switching the fixed plate 1 from the hole plate taking and placing state to the hole plate using state and in the hole plate using state, the hole plate clamping member 4 can be driven to rotate so that the clamping end 41 approaches the first corner of the hole plate 100 to form a diagonal clamping of the hole plate 100 together with the right-angle stop structure. When the fixed plate 1 is in the hole plate taking and placing state, the hole plate clamping member 4 can be driven to rotate reversely so that the clamping end 41 is away from and disengaged from the first corner.

[0043] In the technical solution, the fixed plate 1 can realize the switching between the hole plate taking and placing state and the hole plate using state in a rotating manner. Meanwhile, the hole plate clamping member 4 on the fixed plate 1 can be released from clamping the hole plate when the fixed plate 1 is in the hole plate taking and placing state, so as to facilitate the operator to take or place the hole plate 100 from or to the rectangular placement area. When the fixed plate 1 is in the hole plate using state and during the state switching process, the hole plate clamping member 4 can clamp the hole plate 100 together with the right-angle stop structure, so as to meet the use purpose of the hole plate 100 after being turned over by 180°. The hole plate clamping member 4 can be clamped or released from clamping the hole plate 100 during the turning over process of the fixed plate 1, and the structure is simple and compact, occupies a smaller space, has a higher space utilization rate, and is beneficial to the compact and small design of the automatic liquid processing workstation to which it is applied.

[0044] In some embodiments, referring to Figure 3As shown, the hole plate clamping piece 4 further comprises a driving end 42, the hole plate clamping piece 4 is rotationally connected with the fixed plate 1 through a first shaft 43, the driving end 42 and the clamping end 41 are respectively located at two sides of the first shaft 43, the fixed plate 1 is provided with a first elastic member 44 (specifically a spring), the first elastic member 44 exerts force on the driving end 42 to make the hole plate clamping piece 4 rotate around the first shaft 43 to approach the hole plate 100 in the hole plate using state, the hole plate turnover device further comprises a first stop block 51 capable of being connected with the support 10, the first stop block 51 is arranged close to the rotating shaft 2 and can exert force on the driving end 42 to drive the hole plate clamping piece 4 to rotate around the first shaft 43 to move away from the hole plate 100 in the hole plate taking and placing state, the foregoing support 10 is a fixed component of the device, the first stop block 51 is fixedly connected with the support 10, that is, the position of the first stop block 51 is fixed, and the rotating shaft 2 can rotate relative to the foregoing support 10.

[0045] In the technical scheme, the elastic force of the first elastic member 44 can make the hole plate clamping piece 4 have a tendency to rotate around the first shaft 43 to approach the hole plate 100, and the first stop block 51 can cooperate with the driving end 42 rotating with the fixed plate 1 to exert force on the hole plate clamping piece 4 to make the hole plate clamping piece 4 have a tendency to rotate around the first shaft 43 in the opposite direction to move away from the hole plate 100, and the final movement of the hole plate clamping piece 4 is finally determined according to the resultant force of the elastic force of the first elastic member 44 on the inner and outer sides of the driving end 42 and the pressing force of the first stop block 51.

[0046] In one specific embodiment, the first stop block 51 has a first protruding arm (not marked in the figure) extending towards one side of the fixed plate 1, the free end face of the first protruding arm is a first inclined surface (not marked in the figure), the first elastic member 44 and the first inclined surface are respectively located at opposite sides of the driving end 42, and in the process of switching the fixed plate 1 from the hole plate using state to the hole plate taking and placing state, the first inclined surface drives the driving end 42 to swing close to the side of the first elastic member 44.

[0047] The first inclined surface is specifically adjusted according to the functional requirements, and the first inclined surface is adopted to form a height difference of the first block 51 in the axial direction of the rotating shaft 2. Since the axial positions of the fixed plate 1 and the first block 51 are fixed, when the driving end 42 of the hole plate clamping piece 4 contacts the first block 51, the driving end 42 will follow the different contact positions of the first inclined surface to overcome the elastic force of the first elastic piece 44 to change the position of the driving end 42, and then change the position of the clamping end 41, that is, switch between clamping and contact clamping of the hole plate 100. It should be particularly pointed out that, as can be seen from the foregoing description, the clamping of the hole plate clamping piece 4 in the present application does not need to separately provide a corresponding power device, but only relies on the relative position change of the first elastic piece 44 and the driving end 42 and the first block 51 to achieve, which is particularly simple and novel in structure.

[0048] Specifically referring to Figure 1 As shown in the drawings, in some embodiments, the right-angle stop structure includes positioning columns 31 arranged at intervals along adjacent right-angle edges of the rectangular placement area. In a specific embodiment, two spaced positioning columns 31 are arranged along the extension direction of each right-angle edge, which can reliably position the opposite-angle area, i.e., the second corner, of the hole plate 100 when the hole plate clamping piece 4 clamps the first corner of the hole plate 100.

[0049] Specifically referring to Figure 4 As shown in the drawings, in some embodiments, the center axis of each positioning column 31 is inclined toward one side of the rectangular placement area, so as to downwardly press the two edges corresponding to the second corner of the hole plate 100 toward the side of the fixed plate 1, thereby preventing the hole plate 100 from being separated from the rectangular placement area due to stress during clamping of the first corner of the hole plate 100. It can be understood that the inclination angles of the positioning columns 31 should be consistent to ensure that the inner sides of the positioning columns 31 can simultaneously contact the corresponding edges of the hole plate 100. Continuing to refer to Figure 1 As shown in the drawings, the outer sides of the lower right-angle edge and the right-angle edge of the rectangular placement area in the illustrated orientation, i.e., the two right-angle edge regions of the first corner of the hole plate 100, are also provided with positioning columns 31 at intervals. The positioning columns 31 in these regions do not need to be inclined, and their main purpose is to form a range area for placing the hole plate 100 together with the aforementioned positioning columns 31 of the second corner. In use, the positioning columns 31 in the two right-angle edge regions of the first corner do not form positioning contact with the hole plate 100.

[0050] In some embodiments, the well plate overturning device further comprises a well plate loosening mechanism (not shown in the figure), which comprises a push plate 61 arranged slidingly on the first side, and a sliding groove (not shown in the figure) is formed on the fixed plate 1 corresponding to the push plate 61, and the push plate 61 is located at the second corner of the well plate 100, and the second corner is located at the diagonal position of the rectangular placement area with respect to the first corner, the push plate 61 has a proximal end position in contact with the second corner and a distal end position not in contact with the second corner, the push plate 61 can be driven to switch between the proximal end position and the distal end position, and when the push plate 61 is at the proximal end position, the push plate 61 exerts a force on the second corner to make the well plate 100 move away from the right-angle stop structure.

[0051] In the technical solution, the push plate 61 can exert a force on the second corner of the well plate 100 when the fixed plate 1 is in the well plate taking and placing state, preventing the phenomenon that the well plate 100 is difficult to be smoothly taken out from the rectangular placement area due to the long-time clamping of the well plate 100 by the right-angle stop structure and the well plate clamping piece 4, that is, the force exerted by the push plate 61 can facilitate the operator to take out the well plate 100.

[0052] Specifically referring to Figure 3 As shown in the figure, the push plate 61 has a swing arm 611, and the swing arm 611 is rotatably connected to the fixed plate 1 through a second shaft 63, the well plate loosening mechanism further comprises a second elastic member 62 (which can also be a spring), the second elastic member 62 is arranged in the fixed plate 1 and exerts a force on the first side of the swing arm 611 to make the push plate 61 rotate away from the well plate 100 around the second shaft 63 to the distal end position in the well plate using state, and the well plate overturning device further comprises a second stop block 52 capable of being connected to the support 10, the second stop block 52 is arranged adjacent to the rotating shaft 2 and can exert a force on the swing arm 611 to drive the push plate 61 to rotate around the second shaft 63 to the proximal end position to overcome the elastic force of the second elastic member 62 in the well plate taking and placing state.

[0053] In the technical solution, the elastic force of the second elastic member 62 can make the push plate 61 have a tendency to rotate away from the well plate 100 around the second shaft 63, and the second stop block 52 can cooperate with the swing arm 611 rotating with the fixed plate 1 to exert a force on the push plate 61 to make the push plate 61 have a tendency to rotate in the opposite direction around the second shaft 63 to approach the well plate 100, and the final movement of the push plate 61 is finally determined by the resultant force of the elastic force of the second elastic member 62 on the inner and outer sides of the swing arm 611 and the pressing force of the second stop block 52.

[0054] In some embodiments, similar to the structure and principle of the first stopper 51, the second stopper 52 has a second protruding arm (not labeled in the figure) extending towards one side of the fixed plate 1, the free end of the second protruding arm has a second inclined surface (not labeled in the figure), and the second elastic member 62 and the second inclined surface are respectively located on opposite sides of the swing arm 611. During the process of switching the fixed plate 1 from the hole plate use state to the hole plate taking and placing state, the second inclined surface drives the driving end 42 to swing towards the side of the second elastic member 62.

[0055] In the technical solution, the direction of the second inclined surface can be reasonably adjusted according to functional requirements. The use of the second inclined surface design can form a height difference in the axial direction of the rotating shaft 2. Since the axial positions of the fixed plate 1 and the second stopper 52 are fixed, when the swing arm 611 contacts the second inclined surface, the swing arm 611 will follow the different contact positions of the second inclined surface to overcome the elastic force of the second elastic member 62 and force the position of the swing arm 611 to change, thereby causing the position of the push plate 61 to change, i.e., switching between pushing the hole plate 100 away or contacting the hole plate 100. It should be particularly noted that, as described above, the sliding of the push plate 61 in the application does not require a separate power device, but only relies on the relative position change between the second elastic member 62 and the second stopper 52 and the swing arm 611, which is particularly simple and novel in structure.

[0056] In some embodiments, when the first stopper 51 has a first protruding arm, a first rolling bearing 421 is connected to the driving end 42, and the first rolling bearing 421 can be in rolling contact with the first inclined surface; and / or a second rolling bearing 612 is connected to the swing arm 611, and the second rolling bearing 612 can be in rolling contact with the second inclined surface. In the technical solution, by providing the first rolling bearing 421 and the second rolling bearing 612, the contact friction between the first inclined surface and the second inclined surface and the corresponding driving end 42 or swing arm 611 can be reduced, and the smoothness of the position switching can be improved.

[0057] The fixed plate 1 described above is specifically assembled by an upper plate 11 and a lower plate 12, and the hole plate clamping member 4 and the push plate 61 and the corresponding first elastic member 44 and the second elastic member 62 are arranged between the upper plate 11 and the lower plate 12.

[0058] Figure 5As shown in the figure, the fixed plate 1 is in the hole plate taking and placing state, the first side of the fixed plate 1 faces upward and is in the horizontal state, the driving end 42 of the hole plate clamping piece 4 is in contact with the highest point of the first inclined surface of the first stopper 51, therefore, the first stopper 51 can overcome the elastic force of the first elastic piece 44 and swing the driving end 42 to the side close to the first elastic piece 44, meanwhile, the clamping end 41 moves away from the first corner of the hole plate 100 to release the clamping of the hole plate 100, meanwhile, the highest point of the second inclined surface of the second stopper 52 is in contact with the swing arm 611, which can overcome the elastic force of the second elastic piece 62 and swing the swing arm 611 to the side close to the second elastic piece 62, meanwhile, the push plate 61 is close to the second corner of the hole plate 100 and exerts force to make the second corner away from the right-angle positioning structure, therefore, the operator can easily take and place the hole plate 100 in this state;

[0059] When the hole plate 100 is placed in the rectangular placing area, the control shaft 2 is rotated by 180° along the first rotation direction, so that the first side of the fixed plate 1 is turned from upward to downward, in the process, the first inclined surface and the second inclined surface are gradually separated from the driving end 42 and the swing arm 611, and under the elastic force of the first elastic piece 44 and the second elastic piece 62, the clamping end 41 of the hole plate clamping piece 4 is close to the first corner of the hole plate 100 to clamp the hole plate 100, and the second elastic piece 62 drives the push plate 61 to be away from the second corner of the hole plate 100; at this time, the hole plate 100 is reliably fixed and positioned in this state, and after the use is completed, the control shaft 2 is rotated by 180° along the second rotation direction, that is, the direction opposite to the first rotation direction, in the process, the first inclined surface and the second inclined surface are gradually in contact with the driving end 42 and the swing arm 611 and finally overcome the elastic force of the first elastic piece 44 and the second elastic piece 62 respectively to make the clamping end 41 away from the first corner of the hole plate 100 and the push plate 61 close to the second corner of the hole plate 100.
