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 chemical laboratories, round-bottomed flasks (whether single-mouth or three-mouth) cannot be placed vertically on the laboratory table because the bottom is not flat. Usually, a ring-shaped flask holder is placed on the table to place the flask on the flask holder. The flask can be tilted at any angle in the vertical direction and can be rotated at will in the horizontal direction.

[0003] However, when the robot performs chemical experiments, if the flask is placed at a non-fixed angle (for example, perpendicular to the table), it will be relatively complicated for the robot to determine the grasping position and it will be difficult to grasp. In addition, since there is no specific place for grasping existing flasks, it is difficult for the robot to directly grasp the existing flasks. Even if the flask is grasped, the stability during the operation cannot be guaranteed, which may cause the flask to slip and the experiment to be interrupted. 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 a chemical experiment operation, so as to enable the robot to grasp or place the round-bottom flask more conveniently and stably, thereby facilitating the operation of the chemical experiment.

[0042] Embodiment 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 through a connecting member, wherein: the first fixing member 1.2 is located on the upper part of 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 connecting member 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 the 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 and forms a fixed angle with the flask bottom clamp 1.1 in the vertical direction. 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 forms the fixed angle with the flask bottom clamp 1.1 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 fixing structure 2.3 and the flask bottom clamp 1.1 (i.e., the length of the line between the flask fixing structure 2.3 and the flask bottom clamp 1.1) is between [ab, a], where: a is the height of the flask, and b is a preset threshold value, which can be set according to actual needs. In this way, when the second fixing member 2.1 is fixed to the first fixing member 1.1 of the flask holder, the flask bottom can just be embedded in the flask bottom clamp 1.1, thereby increasing the stability of the flask.

[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°. Figure 2a to 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 where the flask bottom clamp 1.1 is located (e.g., perpendicular to the desktop).

[0049] Wherein: the flask bottom clamp 1.1 includes: an inner concave portion 1.11 matching the bottom of the round-bottom flask to be placed, and the edge of the inner concave portion 1.11 can be provided with a corresponding inner concave extension portion 1.12 according 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 the three-necked flask includes a round bottom facing the middle mouth, and two side bottoms corresponding to the positions of the other two side mouths on both sides of the round bottom and having a size smaller than the round bottom, two extension portions 1.12 matching the side bottoms can be provided on both sides of the edge of the inner concave portion 1.11, respectively, to ensure that when the flask is placed in the flask bottom clamp 1.1, the flask bottom fits tightly with the flask bottom clamp 1.1, thereby improving the stability of the flask.

[0050] In one example, a mortise and tenon structure may 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 comprises: 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 matching the inclined groove 1.31 and a slot fixing portion 2.12 matching 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 adsorbent can be provided in the slot fixing portion 2.12, so that the round-bottom flask placement bracket can be adsorbed on other experimental devices through the adsorbent during the experiment. The adsorbent can be made of iron sheets, magnets, 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-bottomed flask to be placed. For example, taking the fixing of a three-necked flask as an example, Figure 3a to 3c The flask fixing structure 2.2 comprises: a hollow supporting member 2.21 and open limiting members 2.22 respectively located on both sides of the supporting member 2.21. The shape and size of the hollow part match the middle port of the round-bottom flask to be placed, and the shape and size of the opening match the other two ports of the round-bottom flask to be placed. Further, the limiting member 2.22 is inclined downward relative to the supporting member 2.21 so as to correspond to the positions of the three ports of the flask, and can facilitate the installation of the flask. The supporting member 2.21 is perpendicular to the two ends of the limiting member 2.22 and is respectively connected to the second fixing member 2.1 and the grasping part 2.3; wherein: the grasping part 2.3 comprises: a first grasping part 2.21 and a second grasping part 2.32 which are parallel and connected to the supporting member 2.21. When clamped, the first grasping part 2.31 and the second grasping part 2.32 are in close contact, so that when the robot grasps, the stability of the flask and the flask connector 2 can be further improved.

[0052] Preferably, the first gripping part 2.21 and the second gripping part 2.32 are made of elastic material (such as thermoplastic polyurethane elastomer (TPU)). In a natural state, the first gripping part 2.21 and the second gripping part 2.32 fit together. Under the action of external force, the first gripping part 2.21 and the second gripping part 2.32 can be separated. When installing the flask, place the flask fixing structure 2.2 just above the flask, and then stick the limiting members 2.22 on both sides to the two side openings of the flask, pry open the first gripping part 2.21 and the second gripping part 2.32, clamp the middle opening of the flask in the hollow of the supporting member 2.21, and move downward until the hollow is completely and tightly fitted to the flask mouth. This ensures that when the robot grabs the gripping part, the middle opening of the flask is in a pinched state, 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] Embodiment 2

[0054] Based on the above 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 into any of the above round-bottom flask placement brackets at a fixed angle, 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, before this step, the flask has been fixed in the flask fixing structure 2.2 in advance. Then the robot can be controlled to locate and grab the grabbing part 2.3, and the grabbing part 2.3 is controlled to move together with the flask connector 2 and the flask. At the same time, the robot locates to the position above the first fixing part 1.2 of the flask holder 1, moves the second fixing part 2.1 of the flask connector 2 to the position above the first fixing part 1.2 of the flask holder 1, and then stops moving.

[0057] S2. Move the gripping part downward to fix the second fixing piece of the flask connector on 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] Embodiment 3

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

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

[0063] S102, moving the flask connecting piece upward at a fixed angle until the second fixing piece is separated 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] Embodiment 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.

When the computer program is executed by one or more data processing devices, the readable medium is able to implement the above-mentioned method of the present invention, namely: clamp the gripping part 2.3 of the flask connector 2 and move it so that the second fixing part 2.1 of the flask connector 2 is located above the first fixing part 1.2 of the flask holder 1; move the gripping part 2.3 downward so that the second fixing part 2.1 of the flask connector 2 is fixed on the first fixing part 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 and forming a fixed angle with the flask bottom clamp 1.1 in the vertical direction; and a second fixing member 2.1 detachably connected to the first fixing member 1.2 is provided in the flask connecting member 2, the second fixing member 2.1 is connected to one end of the flask fixing structure 2.2, the flask fixing structure 2.2 and the flask bottom clamp 1.1 form the fixed angle in the vertical direction, and the other end of the flask fixing structure 2.2 is connected to the grabbing part 2.3. When in use, the mouth of the flask is fixed in the flask fixing structure 2.2, and the robot clamps the gripping part 2.3 of the flask connector 2 and moves so that the second fixing part 2.1 of the flask connector 2 is located above the first fixing part 1.2 of the flask holder 1; the gripping part 2.3 is moved downward so that the second fixing part 2.1 of the flask connector 2 is fixed on the first fixing part 1.2 of the flask holder 1, and at the same time, the bottom of the flask is embedded in the flask bottom clamp 1.1, so that the flask can be stably placed in the flask holder at a fixed angle.
