Description

Technical Field

[0001] This utility model relates to the technical field of reagent bottle processing equipment, and in particular to a reagent bottle stoppering device compatible with multiple specifications. Background Technology

[0002] In fields such as biopharmaceuticals, in vitro diagnostics, and chemical experiments, automated stoppering of reagent bottles is a crucial step in ensuring production efficiency and sealing quality. Existing automated stoppering devices are typically designed for large-scale, single-specification production lines, using sophisticated mechanical structures to achieve high-speed, continuous stoppering of reagent bottles of specific sizes.

[0003] However, with the diversification of scientific research activities and market demands, laboratories or manufacturers often need to handle small-batch, multi-batch production tasks. These tasks involve reagent bottles with very different specifications, such as bottle diameter, bottle height, and bottle shape.

[0004] Faced with such diverse production demands, the limitations of existing stoppering devices become apparent. These devices typically have fixed or very limited adjustable clamping and positioning structures. Changing to a different size reagent bottle requires significant time for equipment downtime, replacement of the entire fixture module, or complex recalibration of the clamping mechanism. This rigid design results in poor equipment compatibility, an inability to quickly respond to different production tasks, severely impacting overall work efficiency and increasing production costs.

[0005] Therefore, this utility model proposes a reagent bottle stopper device compatible with multiple specifications to overcome the shortcomings of the prior art. Utility Model Content

The trapezoidal lead screw is vertically arranged on the fixed frame, the lifting seat is threadedly connected to the trapezoidal lead screw, and the bottle fixing pad is detachably connected to the lifting seat. The bottle fixing pad can reciprocate horizontally through the clamping hole to extend into or leave the fixture groove.

[0008] Preferably, an elastic guide ring is provided on the inner wall of the fixture groove, and a second spring is connected between the elastic guide ring and the groove wall of the fixture groove.

[0009] Preferably, the bottom of the fixture groove is provided with a drainage hole.

[0019] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0020] A multi-size compatible reagent bottle stopper device, as described in the reference. Figures 1-6 The device includes a base 1, a fixture assembly 2 mounted on the base 1, and a bottle fixing assembly 3 mounted on the base 1. The device also includes a bracket 4, a two-axis linear motion module 5, and a rotating gripper 6. The bracket 4 is fixed on the base 1, the two-axis linear motion module 5 is fixed on the bracket 4, and the rotating gripper 6 is connected to the moving end of the two-axis linear motion module 5. The bottle-holding assembly 3 is used to precisely and adjustablely clamp reagent bottles placed within the fixture assembly 2. Specifically, the bottle-holding assembly 3 includes a fixing base 301, which is fixed to the base 1. A lead screw motor 302 is fixed to the fixing base 301. The output end of the lead screw motor 302 is threadedly connected to a slider 303, which is fixedly connected to a fixing frame 304. By rotating the lead screw motor 302, the slider 303 and the fixing frame 304 can be driven to achieve horizontal positioning. The reciprocating linear motion is as follows: A trapezoidal lead screw 305 is vertically arranged on the fixed frame 304, and a lifting seat 307 is threadedly connected to the trapezoidal lead screw 305. A bottle-fixing pad 310 is detachably connected to the lifting seat 307. A clamping hole 203 is opened on the fixture assembly 2 at the position corresponding to the bottle-fixing pad 310. The bottle-fixing pad 310 can reciprocate horizontally through the clamping hole 203 to extend into or leave the fixture groove 211 in the fixture assembly 2, thereby clamping or releasing the reagent bottle. To achieve compatibility with reagent bottles of different heights, a rotating handle 306 is fixedly connected to the top of the trapezoidal lead screw 305. By manually rotating the rotating handle 306, the trapezoidal lead screw 305 can be rotated. Since the lifting seat 307 and the trapezoidal lead screw 305 are connected by threads, the lifting seat 307 will move up and down along the axis of the trapezoidal lead screw 305, thereby driving the bottle holder 310 to rise and fall as a whole to adapt to the clamping requirements of different heights. To achieve compatibility with reagent bottles of different shapes, the connection structure of the bottle holder 310 is as follows: a mounting sleeve 308 is fixed on the lifting seat 307, and a T-shaped groove 309 is provided on the mounting sleeve 308; a T-shaped block 311 is fixed on the side wall of the bottle holder 310, and the T-shaped block 311 is slidably connected to the T-shaped groove 309. When replacement is required, the bottle holder 310 can be slid out along the length of the T-shaped groove 309, and then another bottle holder 310 matching the new specification reagent bottle can be installed. An elastic guide ring 213 is provided on the inner wall of the fixture groove 211 of the fixture assembly 2. A second spring 214 is connected between the elastic guide ring 213 and the groove wall of the fixture groove 211. When the reagent bottle is placed into the fixture groove 211, the second spring 214 can provide radial elastic force to drive the elastic guide ring 213 to adaptively conform to the bottle body of different diameters, thereby achieving preliminary centering and flexible clamping of the bottle body. In addition, a drain hole 212 is provided at the bottom of the fixture groove 211 to facilitate the discharge of residual liquid during equipment cleaning.

[0021] The fixture assembly 2 includes a mounting plate 201 and a fixture plate 202. The mounting plate 201 is fixed to the base 1 by bolts. The fixture plate 202 has the aforementioned fixture groove 211 and clamping hole 203. The fixture plate 202 is slidably positioned with the mounting plate 201 by a positioning pin 204. In order to lock the fixture plate 202 on the mounting plate 201, the fixture assembly 2 is also provided with a pin 205, which can be inserted into the mounting plate 201. A knob 206 is rotatably connected to the pin 205, and a threaded block 207 is fixedly connected to the knob 206. When the operator rotates the knob 206, the threaded block 207 slides spirally inside the pin 205 and compresses the first spring 208 fixed at one end. The other end of the first spring 208 is connected to a push block 209. The compressed first spring 208 pushes the push block 209, which in turn drives the ball 210 to extend out of the side wall hole of the pin 205 and lock into the preset groove inside the mounting plate 201. Through the locking action of the ball 210, the jig plate 202 is firmly fixed on the mounting plate 201. When it is necessary to disassemble and replace the jig plate 202, the knob 206 is rotated in the opposite direction or the pin 205 is pulled out directly. The ball 210 retracts into the pin 205 under external constraint. At this time, the compressed first spring 208 rebounds and generates an auxiliary thrust, which helps the operator to easily separate the jig plate 202 from the mounting plate 201. The motion and actuation mechanism of this multi-size compatible reagent bottle stoppering device includes a bracket 4, a two-axis linear motion module 5, and a rotating gripper 6. The bracket 4 is fixed on the base 1, providing a stable mounting platform for the two-axis linear motion module 5. The two-axis linear motion module 5 is fixed on the bracket 4 and can drive its moving end to perform precise linear motion in both horizontal and vertical dimensions. The rotating gripper 6, as an end effector, is connected to the moving end of the two-axis linear motion module 5 and is used to perform subsequent stopper gripping and stoppering actions. To enable rapid switching between clamping reagent bottles of different shapes, a mounting sleeve 308 is fixed on the lifting seat 307, and a T-slot 309 is formed on the mounting sleeve 308. A T-block 311 matching the T-slot 309 is fixed on the side wall of the bottle-fixing pad 310. The T-block 311 and the T-slot 309 form a sliding connection, allowing the bottle-fixing pad 310 to be easily removed from or installed on the mounting sleeve 308. To facilitate manual adjustment of the clamping height by the operator, a rotating handle 306 is fixedly connected to the top of the trapezoidal screw 305. The lifting seat 307 can be moved up and down by rotating the handle 306. In order to better accommodate reagent bottles of different diameters, an annular elastic guide ring 213 is provided on the inner wall of the fixture trough 211. The elastic guide ring 213 is connected to the trough wall of the fixture trough 211 by multiple circumferentially distributed second springs 214 to ensure that the elastic guide ring 213 can provide uniform radial support force when the bottle is placed in. A drain hole 212 is provided at the lowest point of the bottom of the fixture trough 211 to ensure that liquid does not accumulate in the fixture trough 211 when cleaning the equipment.

[0022] Working principle: When performing the stoppering operation, the reagent bottle to be processed is first placed in the fixture groove 211 of the fixture assembly 2. The elastic guide ring 213 in the fixture groove 211 will adaptively and flexibly pre-position the bottle body of different diameters under the action of the second spring 214. Then, the bottle fixing assembly 3 is started, and the lead screw motor 302 drives the slider 303 and the fixing frame 304 to move horizontally, thereby driving the bottle fixing pad 310 on the lifting seat 307 to enter the fixture groove 211 through the clamping hole 203, applying clamping force to the bottle body of the reagent bottle to achieve a stable rigid fixation. When it is necessary to change reagent bottles of different heights, the operator can turn the rotating handle 306 to drive the trapezoidal screw 305 to rotate, thereby causing the lifting seat 307 threaded on the trapezoidal screw 305 to move up and down, adjusting the bottle fixing pad 310 to a suitable clamping height. When it is necessary to change reagent bottles of different shapes, the bottle fixing pad 310 can be removed from the mounting sleeve 308 through the sliding engagement of the T-block 311 and the T-slot 309, and replaced with a new bottle fixing pad 310. After the reagent bottle is clamped and fixed, the two-axis linear motion module 5 is started. The two-axis linear motion module 5 drives the rotating gripper 6 to move horizontally and vertically to directly above the reagent bottle. Then the rotating gripper 6 performs the stoppering action. After the stoppering is completed, the screw motor 302 of the bottle fixing assembly 3 rotates in the opposite direction, causing the bottle fixing pad 310 to release the reagent bottle. The two-axis linear motion module 5 drives the rotating gripper 6 to reset. When it is necessary to replace the entire batch of fixture plates 202, the operator turns the knob 206, and through the linkage of the threaded block 207, the first spring 208 and the push block 209, the ball 210 retracts from the locking position of the mounting plate 201. Then, with the assistance of the rebound force of the first spring 208, the fixture plate 202 can be quickly removed along the positioning post 204, realizing the rapid replacement of the entire plate.
