Description

Technical Field

[0001] The invention relates to the technical field of automatic control chemical experimental instruments, in particular to a round-bottom flask placement support and a method. Background Art

[0002] In traditional chemistry labs, round-bottom flasks (whether single-necked or triple-necked) cannot be placed vertically on the bench due to their uneven bottoms. Instead, they are typically placed on a circular flask holder. This allows the flask to be tilted vertically at any angle and rotated horizontally.

[0003] However, when performing chemical experiments, if the flask is placed at an angle other than a fixed one (for example, perpendicular to the table), the robot's grasping position becomes complex and difficult to determine. Furthermore, since existing flasks lack a specific gripping area, it's difficult for the robot to directly grasp them. Even if it does manage to grasp the flask, it can't be held securely during operation, potentially causing it to slip and interrupt the experiment. Summary of the Invention

[0041] The round-bottom flask placement bracket and method provided by the present invention can be applied to the process of a robot performing chemical experiment operations, so as to enable the robot to grasp or place the round-bottom flask more conveniently and stably, thereby facilitating the operation of chemical experiments.

[0042] Example 1

[0043] refer to Figure 1a and 1b , Embodiment 1 of the present invention provides a round-bottom flask placement bracket, comprising: a flask holder 1 and a flask connector 2;

[0044] The flask holder 1 comprises: a flask bottom clamp 1.1 and a first fixing member 1.2 connected to the flask bottom clamp 1.1 via a connecting member, wherein the first fixing member 1.2 is located above the flask bottom clamp 1.1 and forms a fixed angle with the flask bottom clamp 1.1 in the vertical direction;

[0045] The flask connector 2 includes: a second fixing member 2.1 located above the first fixing member 1.2 and detachably connected to the first fixing member 1.2, the second fixing member 2.1 is connected to one end of a flask fixing structure 2.2, the flask fixing structure 2.2 and the flask bottom clamp 1.1 form a fixed angle in the vertical direction, and the other end of the flask fixing structure 2.2 is connected to a gripping portion 2.3.

[0046] The present invention provides a first fixing member 1.2 on the upper part of the flask bottom clamp 1.1, which is fixed at a vertical angle to the flask bottom clamp 1.1. Since the second fixing member 2.1 is located above the first fixing member 1.1 and is detachably connected to the first fixing member 1.1, and at the same time, the second fixing member 2.1 is connected to one end of a flask fixing structure 2.3, and the flask fixing structure 2.3 and the flask bottom clamp 1.1 form the fixed angle in the vertical direction, it is ensured that the flask can be placed in the flask bottom clamp 1.1 at a fixed angle.

[0047] Furthermore, the distance between the flask-securing structure 2.3 and the flask bottom clamp 1.1 (i.e., the length of the line connecting the flask-securing structure 2.3 and the flask bottom clamp 1.1) is between [ab, a], where a is the flask height and b is a preset threshold value, which can be set according to actual needs. Thus, when the second fixing member 2.1 is secured to the first fixing member 1.1 of the flask holder, the flask bottom fits neatly into the flask bottom clamp 1.1, enhancing the flask's stability.

[0048] In this embodiment, the fixed angle can be set to any angle according to actual needs. In a preferred example, the fixed angle is 90°. Figures 2a-2c The flask bottom clamp 1.1 is connected to the first fixing member 1.2 via a vertical connecting member 1.3, and the flask fixing structure 2.2 is located directly above the flask bottom clamp 1.1 (i.e., the flask fixing structure 2.2 forms a 90° angle with the flask bottom clamp 1.1 in the vertical direction). This ensures that the flask is placed in the flask bottom clamp 1.1 at an angle perpendicular to the horizontal plane of the flask bottom clamp 1.1 (e.g., perpendicular to the tabletop).

[0049] The flask bottom fixture 1.1 includes an inner recess 1.11 that matches the bottom of the round-bottom flask to be placed. The edge of the inner recess 1.11 can be provided with an inner recess extension 1.12 corresponding to the shape and size of the bottom of the round-bottom flask to be placed. Taking a three-necked flask as an example, since the bottom of a three-necked flask includes a round bottom directly opposite the center opening and two side bottoms smaller than the round bottom located on either side of the round bottom, corresponding to the other two side openings, two extensions 1.12 matching the side bottoms can be provided on either side of the edge of the inner recess 1.11 to ensure that when the flask is placed in the flask bottom fixture 1.1, the flask bottom and the flask bottom fixture 1.1 are tightly fitted, thereby improving the stability of the flask.

[0050] In one example, a mortise and tenon structure can be used between the first fixing member 1.2 and the second fixing member 2.1 to achieve a detachable connection between the two and ensure the stability of the connection between the two. Figure 2a The first fixing member 1.2 includes: a concave slot 1.21, and the top of the vertical connecting member 1.3 is provided with an inclined slot 1.31, and the inclined slot 1.31 is connected with the slot 1.21 to form a mortise and tenon structure composed of straight edges and oblique edges. Figure 3a The second fixing member 2.1 includes: an inclined fixing portion 2.11 that matches the inclined groove 1.31 and a slot fixing portion 2.12 that matches the slot 1.21, so that the inclined fixing portion 2.11 and the slot fixing portion 2.12 are tightly embedded in the inclined groove 1.31 and the slot 1.21, respectively. Furthermore, an adsorption member can be provided within the slot fixing portion 2.12 to facilitate adsorption of the round-bottom flask placement bracket to other experimental devices during the experiment. The adsorption member can be made of an iron sheet, a magnet, etc., and corresponding magnets or iron sheets can be provided on other experimental devices.

[0051] In this embodiment, the flask fixing structure 2.2 is used to fix the flask mouth, and can be designed according to the number and structure of the mouths of the round bottom flask to be placed. For example, taking the fixing of a three-necked flask as an example, Figures 3a-3c The flask-fixing structure 2.2 comprises a hollow supporting member 2.21 and two open stoppers 2.22 located on either side of the supporting member 2.21. The hollow shape and size match the center opening of the round-bottom flask to be placed, while the shape and size of the open opening match the other two openings of the round-bottom flask to be placed. Furthermore, the stoppers 2.22 are tilted downward relative to the supporting member 2.21 to align with the three openings of the flask, facilitating flask installation. The supporting member 2.21, perpendicular to the stoppers 2.22, is connected to the second fixing member 2.1 and the gripping portion 2.3 at both ends, respectively. The gripping portion 2.3 comprises a first gripping portion 2.21 and a second gripping portion 2.32, which are parallel and connected to the supporting member 2.21. When clamped, the first gripping portion 2.31 and the second gripping portion 2.32 are in close contact, thereby further enhancing the stability of the flask and the flask connector 2 during robot grasping.

[0052] Preferably, the first gripping portion 2.21 and the second gripping portion 2.32 are made of an elastic material (such as thermoplastic polyurethane (TPU)). In their natural state, the first gripping portion 2.21 and the second gripping portion 2.32 fit together. Under the action of an external force, the first gripping portion 2.21 and the second gripping portion 2.32 can be separated. When installing the flask, the flask fixing structure 2.2 is placed directly above the flask, and then the limiting members 2.22 on both sides are placed against the two side openings of the flask. The first gripping portion 2.21 and the second gripping portion 2.32 are pried apart, and the middle opening of the flask is clamped in the hollow of the supporting member 2.21, and moved downward until the hollow is completely and tightly fitted with the flask opening. This ensures that when the robot grasps the gripping portion, the middle opening of the flask is pinched, and the two side openings of the flask cannot rotate because they are completely supported by the limiting members 2.22 on both sides.

[0053] Example 2

[0054] Based on the above-mentioned round-bottom flask placement bracket, the second embodiment of the present invention further provides a round-bottom flask placement method, which is used to control the experimental robot to place the round-bottom flask at a fixed angle into any one of the above-mentioned round-bottom flask placement brackets, such as Figure 4 Said method comprises:

[0055] S1. Clamp the gripping portion of the flask connector and move it so that the second fixing piece of the flask connector is located above the first fixing piece of the flask holder.

[0056] Preferably, the flask has already been secured in the flask securing structure 2.2 prior to this step. The robot can then be controlled to locate and grasp the grasping portion 2.3. By controlling the robot to move the grasping portion 2.3, the flask connector 2 and the flask are moved together. Simultaneously, the robot locates itself above the first securing member 1.2 of the flask holder 1, moves the second securing member 2.1 of the flask connector 2 to a position above the first securing member 1.2 of the flask holder 1, and then stops.

[0057] S2. Move the gripping portion downward to fix the second fixing piece of the flask connector to the first fixing piece of the flask holder.

[0058] Specifically, this step can control the robot to move the grasping part 2.3 downward until the inclined fixing part 2.11 and the slot fixing part 2.12 of the second fixing part 2.1 are respectively embedded in the inclined groove 1.31 of the vertical connecting part 1.3 and the slot 1.21 of the first fixing part 1.2, so that the second fixing part 2.1 of the flask connecting part 2 is fixed on the first fixing part 1.2 of the flask holder 1. At the same time, since the flask fixing structure 2.2 and the flask bottom clamp 1.1 form a fixed angle in the vertical direction, when the second fixing part 2.1 is fixed on the first fixing part 1.2 of the flask holder 1, the flask bottom can just be embedded in the flask bottom clamp 1.1, thereby ensuring that the flask is placed in the flask bottom clamp 1.1 at a fixed angle.

[0059] Example 3

[0060] Based on the above-mentioned round-bottom flask placement bracket, the third embodiment of the present invention further provides a round-bottom flask removal method, which is used to control the experimental robot to remove the round-bottom flask from any of the above-mentioned round-bottom flask placement brackets at a fixed angle, such as Figure 5 As shown, the method includes:

[0061] S101, clamping the gripping portion of the flask connector;

[0062] This step can control the robot to position and clamp the gripping part 2.3.

[0063] S102, moving the flask connecting piece upward at a fixed angle until the second fixing piece is disengaged from the first fixing piece of the flask holder.

[0064] By controlling the robot to move the grabbing part 2.3, the flask connector 2 and the flask are moved together. When the second fixing part 2.1 is disengaged from the first fixing part 1.2 of the flask holder 1, the flask bottom is also disengaged from the flask bottom clamp 1.1, and the flask is taken out from the round-bottom flask placement bracket.

[0065] Example 4

[0066] Based on the method provided in the second embodiment, the fourth embodiment of the present invention provides a readable storage medium, such as Figure 6As shown, the computer program for executing the above method can be stored on one or more readable media. The readable medium can be a readable signal medium or a readable storage medium. The readable storage medium can be, for example, but not limited to, an electronic device, device or component of electricity, magnetism, light, electromagnetic, infrared, or semiconductor, or any combination thereof. More specific examples (non-exhaustive list) of readable storage media include: an electrical connection with one or more wires, a portable disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disk read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination thereof. When the computer program is executed by one or more data processing devices, the readable medium is enabled to implement the above-mentioned method of the present invention, namely: clamping the gripping portion 2.3 of the flask connector 2 and moving it so that the second fixing member 2.1 of the flask connector 2 is located above the first fixing member 1.2 of the flask holder 1; moving the gripping portion 2.3 downward so that the second fixing member 2.1 of the flask connector 2 is fixed on the first fixing member 1.2 of the flask holder 1.

[0067] In summary, the round-bottom flask placement bracket and method provided by the present invention are provided with a first fixing member 1.2 on the upper part of the flask bottom clamp 1.1, which is fixed at a vertical angle to the flask bottom clamp 1.1; and a second fixing member 2.1 detachably connected to the first fixing member 1.2 is provided in the flask connector 2, and the second fixing member 2.1 is connected to one end of the flask fixing structure 2.2, and the flask fixing structure 2.2 forms the fixed angle with the flask bottom clamp 1.1 in the vertical direction, and the other end of the flask fixing structure 2.2 is connected to the gripping part 2.3. During use, the flask mouth is fixed to the flask fixing structure 2.2. The robot clamps the gripping portion 2.3 of the flask connector 2 and moves it so that the second fixing member 2.1 of the flask connector 2 is located above the first fixing member 1.2 of the flask holder 1. The gripping portion 2.3 is moved downward to fix the second fixing member 2.1 of the flask connector 2 to the first fixing member 1.2 of the flask holder 1. At the same time, the bottom of the flask is embedded in the flask bottom clamp 1.1, and the flask can be stably placed in the flask holder at a fixed angle. Compared with the existing technology, the present invention has at least the following beneficial effects:

[0068] 1. A first fixing member 1.2 is provided on the upper portion of the flask bottom clamp 1.1 at a fixed angle to the flask bottom clamp 1.1 in the vertical direction.

[0069] 2. A gripping portion 2.3 connected to the flask fixing structure 2.2 is provided to facilitate the experimental robot to locate the gripping position and to firmly grip the flask to prevent the flask from falling.
