Description

Technical Field

[0001] This utility model relates to the field of automated instrument technology, and more specifically, to an automated instrument adapter for a skirtless PCR plate. Background Technology

[0002] Skirtless PCR plates are devices used in PCR preparation to achieve temperature conduction, high-temperature sterilization, and prevent contamination. They are also common consumables in molecular experiments. While skirtless PCR plates are compatible with all PCR instruments, they cannot provide stability during the pipetting process of automated instruments when constructing reaction systems. Furthermore, they lack sufficient mechanical strength to securely hold the plates in place during automated instrument operations, particularly during liquid aspiration, dispensing, and movement. This displacement can lead to aspiration / dispensing failures and experimental termination. Utility Model Content

[0003] The purpose of this invention is to provide an automated instrument adapter for skirtless PCR plates, which can securely and stably fix the skirtless PCR plates onto automated instruments and is compatible with various brands and models of automated instruments to meet experimental needs.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An automated instrument adapter for a skirtless PCR plate includes a base, edge panels, a cover plate, slots, and limiters. The base has slots with guide grooves inside, which facilitate precise docking and positioning of the PCR plate by the automated instrument, ensuring accurate positioning and reducing errors during automated operation. The edge panels are fixedly connected to the base, and there are four edge panels forming a rectangular frame around the base. The cover plate is located above the edge panels, and has through holes corresponding to the slots on the base. Limiters are provided around the slots.

[0006] As an improvement of this utility model, the inner side of the through hole of the cover plate is a conical or stepped structure for precise docking with the PCR plate and enhancing the fixation effect; the limiter is a symmetrical semi-circular structure with a nylon material covering the surface to enhance friction and ensure that the PCR plate is stably positioned in the adapter.

[0007] As an improvement of this utility model, the length of the long side of the edge panel is 129mm and the height is 12mm; the length of the wide side is 84mm and the height is 12mm; the length of the cover plate is 129mm, the width is 84mm and the height is 1mm, and the upper left corner has the letter A1 to facilitate the robot to identify the position of the PCR plate.

[0008] As an improvement of this utility model, the number of holes and slots is 96, the diameter of the holes and slots is 6.5mm, the distance between the holes and slots is 3mm, the lateral distance between the edge holes and slots and the edge panel is 10mm, and the longitudinal distance is 6mm.

[0009] As an improvement of this utility model, the outer side of the hole groove is provided with threads, and the limiter is fixed around the hole groove by the threads, which can be finely adjusted according to the PCR plate of different thicknesses to ensure that the plate is always in a stable position and adapt to the needs of different automated equipment.

[0010] As an improvement of this utility model, anti-slip mechanisms are provided on both sides of the edge panel. The anti-slip mechanisms are made of rubber pads or suede material and are fixed to the edge panel by means of buckles or bolts. They are used to increase the friction when the robot gripper contacts the PCR plate and prevent shaking during automated operation.

[0011] The skirtless PCR plate automated instrument adapter of this utility model has the following beneficial effects:

[0012] (1) The adapter provided in this application includes a base, four edge panels, a cover plate, slots, and a limiter. The base has multiple slots, and the slots have guide grooves inside, which enable the PCR plate to be precisely aligned in automated equipment. The guide grooves are designed so that the PCR plate can enter the slot position under the precise control of the automated equipment, reducing errors.

[0013] (2) The four edge panels of this application form a rectangular frame around the base. These edge panels are fixed to the base by snaps or bolts and connected to the limiters by fixing threads. The design of the edge panels provides good structural strength and provides suitable support so that the PCR plate will not shake during operation, thus enhancing stability.

[0014] (3) The cover plate of this application is located above the edge panel, and the cover plate is provided with through holes corresponding to the base slots to ensure the placement and positioning of the PCR plate. At the same time, the inner side of the cover plate is designed with a conical or stepped structure to further improve the precise docking capability of the PCR plate and ensure that the plate does not shift.

[0015] (4) The limiter of this application has a semi-circular structure and the surface is covered with a wear-resistant material (such as nylon or suede), and is fixed around the slot by threads. This design allows for fine adjustment according to PCR plates of different thicknesses, thereby ensuring that PCR plates of different sizes can be stably placed in the adapter.

[0016] (5) The edge panel of this application is also provided with anti-slip mechanism on both sides, which enhances the friction between the gripper of the automated equipment and prevents slippage or displacement during gripping and operation. Attached Figure Description

[0031] First, align the upper left corner A of the skirtless PCR plate with position A1 on the adapter. Ensure that each well 7 of the PCR plate is precisely aligned with the well 7 on the adapter base 1. Place the skirtless PCR plate into the well 7 of the adapter, ensuring that the well 7 corresponds one-to-one with the well position of the PCR plate.
