Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically to an automatic opening and closing lid mechanism for laboratory use. Background Technology

[0002] In laboratory sample preparation, various bottles and containers require opening and closing caps. Conventional opening and closing operations are manual, resulting in uncontrollable tightening force and inconsistent capping quality. This poses a risk of spillage during the transfer of hazardous liquids, impacting operator health and the surrounding environment. Currently, to protect operator safety, prevent sample contamination, and maintain a stable experimental environment, automated laboratory capping mechanisms are typically used to automatically open and close bottles.

[0003] Automatic cap opening and closing mechanisms for laboratory use on the market usually do not have multiple limiting mechanisms and typically use a single clamping method, which makes it difficult to adapt to bottles of different diameters and materials, and can easily lead to problems such as unstable clamping, bottle damage or slippage. Therefore, we propose an automatic cap opening and closing mechanism for laboratory use. Utility Model Content

[0004] The purpose of this invention is to provide an automatic opening and closing lid mechanism for laboratory use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic opening and closing cover mechanism for laboratory use, comprising a support plate and a limiting component. The support plate is an integrated structure, and a fixed plate is installed on the top of the support plate. The support plate is symmetrically arranged at both ends of the lower surface of the fixed plate. The limiting component is disposed on the surface of the fixed plate and includes a three-jaw clamping cylinder, a three-jaw gripper, a placement carrier, a two-jaw clamping cylinder, a two-jaw gripper, a fixed sheet metal part, and a pressure regulating valve. The three-jaw clamping cylinder is disposed on the upper side of the fixed plate, and a three-jaw gripper is installed on the upper side of the three-jaw clamping cylinder. A placement carrier is installed on the front right side of the upper right end of the fixed plate, and a two-jaw clamping cylinder is disposed on the right side of the placement carrier. A two-jaw gripper is installed on the left side of the two-jaw clamping cylinder.

[0006] Furthermore, the support plate and the fixing plate are an integrated structure that is tightly connected, and a fixing sheet metal part is provided behind the support plate.

[0007] Furthermore, the fixed sheet metal part is an integrated structure, and a pressure regulating valve is provided on the surface of the fixed sheet metal part.

[0008] Furthermore, a protective plate is installed on the left side of the fixing plate, and a supporting upright plate is provided on the right side of the fixing plate.

[0009] Furthermore, the surface of the support plate is provided with movable components for assisting opening and closing, and the movable components include a hydraulic push rod, a support frame, a servo motor, a threaded screw, and a movable block.

[0010] Furthermore, the hydraulic push rod is located on the upper right surface of the support plate, and a support frame is installed on the left end of the hydraulic push rod, with a servo motor located on the rear side of the support frame.

[0011] Furthermore, the output end of the servo motor is connected to a threaded screw via a coupling, and a movable block is threadedly connected to the surface of the threaded screw. The outer surface of the movable block is slidably connected to the inner surface of the support frame.

[0012] Furthermore, the movable component also includes a protective cover, a rotating motor, and a movable gripper. The protective cover is installed at the bottom of the movable block, and the rotating motor is installed inside the protective cover. The output end of the rotating motor is connected to the movable gripper via a coupling.

[0013] This utility model provides an automatic opening and closing lid mechanism for laboratory use, which has the following advantages: 1. This utility model incorporates a limiting component, which includes a three-jaw clamping cylinder, a three-jaw gripper, a placement carrier, a two-jaw clamping cylinder, a two-jaw gripper, a fixed sheet metal part, and a pressure regulating valve. In use, a larger-diameter bottle is placed on the three-jaw gripper, and the three-jaw clamping cylinder drives the three-jaw gripper to clamp and limit the larger-diameter bottle. A smaller-diameter bottle is placed on the placement carrier, and the two-jaw clamping cylinder drives the two-jaw gripper to fix and limit the smaller-diameter bottle. By adjusting the pressure regulating valve, the pressure of the three-jaw gripper and the two-jaw gripper reaches the corresponding clamping force to accommodate bottles of different soft and hard materials. Thus, this device uses three-jaw / two-jaw cylinders for type-specific clamping and the pressure regulating valve for pressure adjustment, stably adapting to bottles of different diameters and soft / hard materials, avoiding slippage or bottle damage problems caused by traditional single-clamping methods.

[0014] 2. This utility model incorporates a movable component, including a hydraulic push rod, a support frame, a servo motor, a threaded screw, and a movable block. The movable component also includes a protective cover, a rotary motor, and a movable gripper. In use, activating the hydraulic push rod moves the support frame left and right to adjust the left-right position of the bottle cap. Activating the servo motor rotates the threaded screw, which in turn drives the movable block to slide along the inner side of the support frame, adjusting the front-back position of the bottle cap. The movable gripper secures the bottle cap. Activating the rotary motor rotates the movable gripper, opening or closing the bottle cap. This allows the device to automatically open and close bottle caps, improving laboratory safety. Attached Figure Description
