[0024] like Figure 1 As shown, the present invention provides a perforated plate holder for easy sample counting, comprising a frame 1. The frame 1 can be integrally molded, with a compact structure and improved space utilization.

[0025] The upper surface of the frame 1 is provided with a perforated plate placement slot, which is used to accommodate perforated plates 2 (such as 96-hole plates). In order to improve the stability of perforated plate placement, in a preferred embodiment, the inner wall of the perforated plate placement slot is provided with an elastic buffer layer 21, such as a rubber pad, to prevent the perforated plates from shifting or colliding after being placed in the placement slot, thereby further improving the practicality and reliability of the perforated plate frame.

[0026] Located on the lateral side edge of the perforated plate placement slot, the upper surface of the frame 1 is marked with numbers 3 (e.g., 1 to 12), and each number 3 corresponds to one-to-one with each column of the perforated plate 2. Located on the longitudinal side edge of the perforated plate placement slot, the upper surface of the frame 1 is marked with letters 4 (e.g., A to H), and each letter 4 corresponds to one-to-one with each row of the perforated plate 2.

[0027] Located on the lateral side edge of the perforated plate placement slot, the frame 1 has a first movable block 5 for lateral movement inside. A first infrared lamp 6 is mounted on the first movable block 5, and the light emitted by the first infrared lamp 6 illuminates one column of the perforated plate 2. Specifically, a first threaded rod 9 is threadedly connected internally to the first movable block 5. One end of the first threaded rod 9 is rotatably connected inside the frame 1, and the other end is connected to the output shaft of a first motor 10, which is fixed inside the frame 1. By activating the first motor 10, the first threaded rod 9 is rotated, thereby achieving the lateral movement of the first movable block 5. In a preferred embodiment, a first slider 11 is formed on the side of the first movable block 5 near the inner wall of the frame 1, and the first slider 11 slides within a track on the inner wall of the frame 1. The cooperation between the first slider 11 and the track improves the stability of the first movable block 5 during movement.

[0028] Located on the longitudinal side edge of the perforated plate placement slot, the frame 1 has a longitudinally movable second block 7 inside, on which a second infrared lamp 8 is mounted. The light emitted by the second infrared lamp 8 illuminates one horizontal row of the perforated plate 2. The surface of the frame 1 is provided with control switches for the first infrared lamp 6 and the second infrared lamp 8.

[0029] Specifically, the second movable block 7 is internally threaded with a second threaded rod 12. One end of the second threaded rod 12 is rotatably connected to the inside of the frame 1, and the other end is connected to the output shaft of the second motor 13, which is fixed inside the frame. By activating the second motor 13, the second threaded rod 12 is rotated, thereby achieving the lateral movement of the second movable block 7. In a preferred embodiment, a second slider 14 is formed on the side of the second movable block 7 near the inner wall of the frame 1, and the second slider 14 slides within a track on the inner wall of the frame 1. The cooperation between the second slider 14 and the track improves the stability of the second movable block 7 during movement.

[0030] The first movable block 5 moves horizontally by one number, corresponding to one column movement; the second movable block 7 moves vertically by one letter, corresponding to one row movement. The intersection of the horizontal and vertical infrared lines is the current sample dispensing hole. This allows for precise sample dispensing and avoids incorrect or missed dispensing.

[0031] To facilitate the removal of the perforated plate, in a preferred embodiment, ear grooves 15 are formed on the upper surface of the frame 1 on both sides of the perforated plate placement groove.

[0032] To improve the stability of the frame when placed on the workbench and to prevent it from shifting during sample addition or sliding due to accidental collisions, the bottom of the frame 1 is provided with an anti-slip pad 16, which further ensures the accuracy and safety of sample addition.

[0033] To facilitate the control of the movement of the first movable block 5 and the second movable block 7, a first self-resetting switch 17 and a second self-resetting switch 18 are provided on the front side of the frame 1. A self-resetting rotary switch is a switch that can automatically return to its initial position, consisting of an operating component, a reset component, a positioning component, and a contact component. The operating component typically consists of a knob cap and a rotating shaft. The knob cap facilitates finger operation, and the rotating shaft connects the knob cap to the internal mechanism, transmitting the rotational action. A common reset component is a torsion spring, which is sleeved on the rotating shaft or rotating base, with its two ends connected to the fixed component and the rotating component respectively, using elastic potential energy to provide the reset force. The positioning component can be a positioning groove, a limit post, a baffle, etc., used to limit the rotation angle of the knob and determine its position in different gears, ensuring the accuracy and stability of operation. The contact component consists of a stationary contact and a moving contact, mounted on a circuit board or base. The rotation of the knob causes the moving contact to contact or separate from the stationary contact, realizing the on / off control of the circuit. The self-resetting rotary switch works as follows: When an external force is applied to the knob cap, causing the knob to rotate around its axis, the rotating base connected to the axis rotates accordingly. The torsion spring is twisted and undergoes elastic deformation, storing elastic potential energy. Simultaneously, the drive pin or positioning pin on the rotating base cooperates with the fixed pin or limit pin fixed to the base to determine the knob's rotation angle and position. When the external force disappears, the torsion spring releases its elastic potential energy, generating a restoring force that pushes the rotating base and knob back to their initial positions. The moving contact also returns to its initial open or closed state, completing the self-resetting process.

[0034] In this embodiment, two self-reset switches are used to control the start and stop of the forward and reverse rotation of the first motor 10 and the second motor 13, respectively. The first motor 10 and the second motor 13 are used to drive the left and right movement of the first movable block 5 and the forward and backward movement of the second movable block 7, respectively. For ease of operation, the knob caps of the first self-reset switches 17 and 18 are connected to levers 19. For example, when the lever of the first self-reset switch 17 is moved forward, the first motor 10 is activated and rotates forward, the first movable block 5 moves one column to the right, the counting module counts once, and when the lever is released, the first self-reset switch 17 resets, the first motor 10 is de-energized, the first movable block 5 stops in this column, the infrared lamp illuminates this column, and the intersection with the horizontal infrared lamp is the current sampling hole, completing the sampling. Similarly, when the first movable block 5 moves to the rightmost column (e.g., number "12"), the sampling for this row is completed. When the lever of the first self-reset switch 17 is moved backward, the first motor 10 is activated and rotates in reverse, returning to the leftmost column (e.g., number "1"). At this point, flicking the lever of the second self-reset switch 18 forward once activates the second motor 13, causing it to rotate forward. The second movable block 7 moves forward one row. Releasing the lever resets the second self-reset switch 18, de-energizes the second motor 13, and illuminates the row with an infrared lamp. The sampling and counting operation from left to right is then performed to complete the sampling for this row. This process is repeated to complete the sampling operation for all sampling holes on all well plates. Simultaneously, flicking the lever of the first self-reset switch 17 forward once counts once, thus completing the counting of all sampling operations. If the initial count of the counting module is "0", the initial position of the first movable block 5 is to the left of the number "1" (equivalent to the "0" position), and the initial position of the second movable block 7 is at the letter "A". Each time the lever of the first self-reset switch 17 is flicked forward, the counting module increments by 1. For example, when the second movable block 7 is located at the letter "A", the first movable block 5 moves from the "0" position to the number "1", and the count is "1". By moving the lever 12 of the first self-reset switch 17 forward, the first movable block 5 is located at the number "12", and the count is "12". Return the first movable block 5 to the initial position, move the second movable block 7 to the letter "B", and move the lever of the first self-reset switch 17 forward once, and the count is "13", and so on.

[0035] In addition, for ease of counting, a display screen 20 is provided on the upper surface of the frame 1. The display screen 20 is electrically connected to the counting module and is used to display the sample quantity. The lever 19 is electrically connected to the counting module. Counting is performed while the lever is being moved, and the result is displayed on the display screen, making experimental operation easier and avoiding errors. For example, if the first movable block 5 is located at the number "1" and the second movable block 7 is located at the letter "A", the display screen 20 will show that the sample quantity is "1". When the first movable block 5 is located at the number "1" and the second movable block 7 is located at the letter "B", the display screen 20 will show that the sample quantity is "13".

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
