Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, specifically to a perforated plate loading structure suitable for robotic arms. Background Technology

[0002] In high-throughput biomedical experiments, 96-well plates, as standardized carriers, are widely used in drug screening, immunoassay, and cell analysis. In molecular biology experiments, to increase throughput, 96-well plates are frequently used for experimental procedures. To fix the 96-well plates, they must be placed on a plate holder. However, existing plate holders lack vertical fixation capabilities. For example, the utility model patent with authorization number CN 221182842 U discloses a 96-well plate holder with a sample loading indicator and a slot for placing the plate, but it lacks vertical fixation. During use, the plate is prone to tipping over, making it inconvenient. Other existing technologies use locking plates, which are complex and require complex locking and unlocking actions, further complicating operation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a perforated plate loading structure suitable for robotic arms, which realizes multi-directional fixation of the perforated plate, has a simple structure, is suitable for robotic arms to pick up, simplifies operation, and avoids the perforated plate tipping over.

[0004] Specifically, this utility model discloses a perforated plate loading structure suitable for robotic arms, comprising:

[0005] The base plate is provided with a receiving surface for receiving the perforated plate;

[0006] Elastic fixing blocks are disposed around the receiving surface to fix the perforated plate;

[0007] A front baffle is fixedly installed on the receiving base plate to limit the perforated plate;

[0008] The rear baffle is fixedly installed on the receiving base plate and is arranged opposite to the front baffle to fix the perforated plate.

[0009] The advantage of adopting the above technical solution is that by setting an elastic fixing block to fix the perforated plate, the perforated plate can be fixed in the vertical direction. When picking up and putting down, there is no need to perform complicated locking and unlocking actions, which ensures that the perforated plate is fixed stably and is easy to pick up.

[0010] Furthermore, the elastic fixing block includes a middle fixing block and a side fixing block. The middle fixing block includes a main body with two side-by-side spring pieces facing opposite directions.

[0011] The advantage of adopting the above technical solution is that the middle fixing block has spring pieces facing two directions, which can fix the perforated plates on both sides, reduce the installation of elastic fixing blocks, and reduce costs.

[0012] Furthermore, the edge fixing block includes a clamping spring sheet disposed on both sides of the perforated plate and facing the perforated plate.

[0013] The advantage of adopting the above technical solution is that by setting a clamping spring facing the perforated plate, the edge of the perforated plate is clamped to ensure that the perforated plate is fixed and stable.

[0014] Furthermore, the perforated plate has a main body, and a fixing part is located at the bottom of the main body. The fixing part protrudes outward, and the spring and the clamping spring press the fixing part together.

[0015] The advantage of adopting the above technical solution is that the fixing part is set to fix it with the clamping spring, so as to ensure that the position of the perforated plate does not move.

[0016] Furthermore, the rear baffle has a guide ramp and a vertical positioning surface, the guide ramp being located above the vertical positioning surface, and the vertical positioning surface being used to position the perforated plate.

[0017] The advantage of adopting the above technical solution is that the setting of the rear baffle guide slope plays a guiding role, allowing for slight errors in the perforated plate during the gripping process. After passing through the guide slope, it reaches the vertical positioning surface, and is positioned by the vertical positioning surface to ensure the position of the perforated plate.

[0018] Furthermore, it also includes a robotic arm for transferring the perforated plate, comprising: a connecting rod and a gripping head, the gripping head being fixedly connected to the connecting rod, the gripping heads being symmetrically arranged for gripping both sides of the perforated plate.

[0019] The advantage of adopting the above technical solution is that the robotic arm is used to grip the perforated plate, realize the picking and placing of the perforated plate, and ensure that the perforated plate is gripped stably.

[0020] Furthermore, the gripping head has protruding ends at both ends. When gripping, the protruding ends squeeze the spring sheet and the clamping spring sheet outward, causing the spring sheet and the clamping spring sheet to deform, so as to remove the perforated plate.

[0021] The advantage of adopting the above technical solution is that during the gripping process, the spring sheet is deformed and retracted by the extended end of the gripping head, and the spring sheet and the clamping spring sheet no longer press against the perforated plate, making it convenient to remove the perforated plate.

[0022] Furthermore, the intermediate fixing block is provided with two connecting parts, and the bottom of the connecting parts is provided with threaded holes for connecting with the receiving base plate. The top of the spring sheet is connected to the main body, and the lower side is bent in two opposite directions.

[0023] The advantage of adopting the above technical solution is that the connecting part is designed to connect with the receiving base plate, and the two spring pieces are bent to both sides, which makes processing convenient and reduces costs. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] like Figure 1-3 As shown, a perforated plate loading structure suitable for robotic arms is disclosed, comprising:

[0036] The base plate 1 is provided with a receiving surface for receiving the perforated plate 2;

[0037] Elastic fixing blocks are disposed around the receiving surface to fix the perforated plate 2;

[0038] The front baffle 3 is fixedly installed on the receiving base plate 1 and is used to limit the perforated plate 2;

[0039] The rear baffle 4 is fixedly installed on the receiving base plate 1 and is arranged opposite to the front baffle 3 to fix the perforated plate 2.

[0040] The advantage of adopting the above technical solution is that by setting an elastic fixing block to fix the hole plate 2, the hole plate 2 is fixed in the vertical direction. By setting it so that no complicated locking and unlocking actions are required when picking it up or putting it down, the hole plate 2 is fixed stably and is easy to pick up.

[0041] Furthermore, the elastic fixing block includes a middle fixing block 5 and an edge fixing block 6, such as... Figure 4 As shown, the intermediate fixing block 5 includes: a main body 51, with two parallel spring pieces 52 arranged in opposite directions; the intermediate fixing block 5 has two connecting parts 53, which are integrally formed with the main body 51 and made of elastic plastic material, which is easy to process and avoids corrosion by solution, and is easy to clean. The bottom of the connecting part 53 has a threaded hole for connecting with the receiving base plate 1. The top of the spring piece 52 is connected to the main body 51 and the lower side is bent in two opposite directions. The intermediate fixing block 5 is fixed in the middle of the receiving base plate 1. During installation, the perforated plate 2 is located on both sides of the receiving base plate 1. The receiving base plate 1 is fixed to the test equipment for receiving reagents and conducting various tests, detections and analyses.

[0042] The middle fixing block 5 has spring pieces 52 facing two directions, which can fix the hole plates 2 on both sides, reducing the installation of elastic fixing blocks and lowering costs.

[0043] Furthermore, the edge fixing block 6 includes those disposed on both sides of the perforated plate 2, such as... Figure 5 As shown, a clamping spring 61 facing the perforated plate 2 is included. The side fixing blocks 6 are also made of plastic and are located on both sides of the perforated plate 2, pressing the sides of the perforated plate 2 together. The side fixing blocks 6 are fixedly installed on the perforated plate 2. The clamping spring 61 faces the perforated plate 2, pressing it firmly. Simultaneously, the clamping spring 61 is elastic and can move towards the side fixing blocks 6, avoiding the perforated plate 2, facilitating its removal. After removal, the spring automatically returns to its original position. The clamping spring 61 facing the perforated plate 2 presses against the edge of the perforated plate 2, ensuring its stable fixation.

[0044] Furthermore, the perforated plate 2 has a main body 21, and a fixing part 22 is located at the bottom of the main body 21. The fixing part 22 protrudes outward, and a spring and a clamping spring 61 press the fixing part 22 together. The upper surface of the main body 21 is provided with a series of receiving holes, and the fixing part 22 is integrally formed with the main body 21. The fixing part 22 is provided to fix the perforated plate 2 to the clamping spring 61, ensuring that the position of the perforated plate 2 does not move.

[0045] Furthermore, the rear baffle 4 has a guide slope 41 and a vertical positioning surface 42. The guide slope 41 is located on the upper side of the vertical positioning surface 42. The vertical positioning surface 42 is used to position the perforated plate 2. The rear baffle 4 is fixedly installed on the receiving base plate 1. It, together with the front baffle 3 and the elastic fixing block, forms a space for placing the perforated plate 2. The perforated plate 2 is pressed by the elastic fixing block to achieve fixation in all directions and in the upper and lower positions, ensuring that the perforated plate 2 will not tip over.

[0046] The rear baffle 4 guide slope 41 serves as a guide, allowing for slight errors in the gripping process of the perforated plate 2. After passing through the guide slope 41, it reaches the vertical positioning surface 42, and is positioned by the vertical positioning surface 42 to ensure the position of the perforated plate 2.

[0047] In some implementations, a robotic arm for transferring the orifice plate 2 is also included, such as Figure 6 As shown, the device includes: a connecting rod 7 and gripping heads 8. The gripping heads 8 are fixedly connected to the connecting rod 7 and are symmetrically arranged for gripping both sides of the perforated plate 2. The robotic arm is connected to the testing equipment and can be driven by a moving module. The moving module can be a lead screw motor module with a cylinder connected to the connecting rod 7, enabling the robotic arm to move up and down and grip, thus transferring the perforated plate 2 and ensuring stable gripping of the perforated plate 2. Other installation methods are also possible. The driving and installation method of the robotic arm is existing technology. Figure 7 The diagram in the middle is a simplified installation diagram and will not be described further here.

[0048] Furthermore, the gripping head 8 has protruding ends 81 at both ends. When gripping, the protruding ends 81 squeeze the spring sheet and the clamping spring sheet 61 outward, causing the spring sheet and the clamping spring sheet 61 to deform and remove the perforated plate 2. The two gripping heads 8 are arranged in parallel. When it is necessary to grip the perforated plate 2, the gripping head 8 moves downward along both sides of the perforated plate 2. At this time, the protruding ends 81 move downward, squeezing the spring sheet and the clamping spring sheet 61 outward, so that the spring sheet no longer presses the perforated plate 2. When the gripping head 8 moves into position, it grips the perforated plate 2 and moves upward to remove the perforated plate 2.

[0049] During the gripping process, the spring sheet is deformed and retracted by the extended end 81 of the gripping head 8, and the spring sheet and the clamping spring sheet 61 no longer press against the perforated plate 2, making it easy to remove the perforated plate 2.

[0050] In operation, the robotic arm first grips the perforated plate 2 and slowly descends from above the base plate 1. The gripping head 8 opens the spring pieces 52 and pressing spring pieces 61 of the middle fixing block 5 and the side fixing block 6. After it is in place, the perforated plate 2 is placed on the base plate 1. During the placement process, it is positioned by the front baffle 3 and the rear baffle 4. After it is in place, the gripping head 8 is released and moves upward. The middle fixing block 5 and the side fixing block 6 press the perforated plate 2 tightly. The perforated plate 2 will not move during use.

[0051] When gripping is required, the gripping head 8 descends along both sides of the perforated plate 2, and again opens the spring pieces and pressing spring pieces 61 of the middle fixing block 5 and the side fixing block 6 to grip the perforated plate 2 and remove the perforated plate 2, thus realizing the automatic picking action of the perforated plate 2. This application restricts the perforated plate 2 in the vertical direction to ensure that the perforated plate 2 will not tip over during use. At the same time, it is suitable for robotic arm gripping, making it easy to pick up without the need for additional disassembly operations.

[0052] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
