[0051] The embodiment of the present application provides a switch cover assembly and a switch cover device, which can automatically complete the opening and closing of the target bottle cap.

[0052] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 It is a schematic structural diagram of the switch cover assembly shown in the embodiment of the present application; Figure 2It is a schematic structural diagram of the cover shown in the embodiments of the present application.

[0054] As Figure 1 shown, the embodiments of the present application provide a switch cover assembly, including a base body 1, a bottle cap clamping member 2 and a pressing member 3. Among them, the bottle cap clamping member 2 is arranged on the base body 1. The bottle cap clamping member 2 includes a first clamping jaw 21, and the first clamping jaw 21 is used to clamp the cover body 40 of the target bottle. The pressing member 3 is movably connected to the base body 1, and the pressing member 3 can move relative to the base body 1 in a first direction. The first direction is the direction in which the cover body 40 moves relative to the bottle body of the target bottle when opening and closing the cap. The pressing member 3 is located on the side of the first clamping jaw 21 away from the bottle body and is used to press the cover body 40 when opening and closing the cap.

[0055] The target bottle can be a test tube, a volumetric flask, a centrifuge tube, etc. The target bottle has a bottle body and a cover body 40 at the upper opening of the bottle body, and the bottle body and the cover body 40 are opened and closed by a press-pull method. The first direction is the up-down direction in the figure. When opening the cap, the cover body 40 moves upward relative to the bottle body until it separates from the bottle body. When closing the cap, the cover body 40 moves downward and is inserted into the opening at the upper end of the bottle body. When opening and closing the cap, the bottle body is located below the first clamping jaw 21. The first clamping jaw 21 clamps the cover body 40, and the pressing member 3 is located above the first clamping jaw 21 and presses the cover body 40 downward. The pressing member 3 can move up and down relative to the base body 1.

[0056] When opening the cap, the first clamping jaw 21 clamps the cover body 40, and the cover body 40 can move upward away from the bottle body in the first direction under the action of the first clamping jaw 21 and separate from the bottle body. In addition, the pressing member 3 can press the cover body 40 before or after pulling the cap. Under the action of the pressing member 3, the pulled-out cover body 40 can be blocked from continuing to move upward, so as to prevent the pulled-out cover body 40 from flying out due to inertia, and keep the cover body 40 between the first clamping jaw 21 and the pressing member 3.

[0057] When closing the cap, the first clamping jaw 21 clamps the cover body 40, the pressing member 3 presses the cover body 40 downward, and the cover body 40 can be inserted into the bottle mouth of the bottle body under the pressing of the pressing member 3 to complete the cap closing operation.

[0058] Therefore, the above solution can automatically complete the opening and closing operations of the target bottle, without manually pulling out and closing the cover body 40 by hand, reducing the labor intensity of the operator and improving the efficiency of the experiment.

[0059] In some embodiments, as Figure 1As shown, the first jaw 21 includes two clamping arms 211 arranged oppositely. On the opposite sides of the two clamping arms 211, there are flanges 212. There is a spacing distance between the two flanges 212. The flange 212 and the pressing member 3 form a receiving space 213 in the first direction. The receiving space 213 is used to receive at least part of the cover body 40. The flange 212 is used to abut against the edge of the cover body 40. The abutting force of the flange 212 against the cover body 40 is opposite to the pressing force of the pressing member 3 against the cover body 40.

[0060] Specifically, when the first jaw 21 clamps the cover body 40, the two clamping arms 211 are located on both sides of the cover body 40 relatively. The spacing distance between the two flanges 212 can be used to accommodate the upper end of the bottle body with an opening. At least part of the cover body 40 is located in the receiving space 213 between the flange 212 and the pressing member 3. The flange 212 abuts against the edge of the cover body 40 upward, and the pressing member 3 presses the cover body 40 downward. The two flanges 212 and the pressing member 3 clamp the cover body 40 up and down, preventing the cover body 40 from being pulled out of the bottle body and moving upward continuously, so as to prevent the pulled-out cover body 40 from flying upward due to inertia.

[0061] In some embodiments, as Figure 2 shown, the cover body 40 has a plug portion 401 and a cap portion 402 located at the upper end of the plug portion 401. The lower end of the plug portion 401 is used to extend into the bottle mouth at the upper end of the bottle body, so that the plug portion 401 seals the bottle mouth. The width of the cap portion 402 is greater than the width of the plug portion 401, and the width of the cap portion 402 is greater than the outer diameter of the upper end of the bottle body. The cap portion 402 and the plug portion 401 are coaxially arranged. When the plug portion 401 blocks the bottle mouth, the cap portion 402 is located outside the bottle mouth. When the first jaw 21 clamps the cover body 40, the two clamping arms 211 are located on both sides of the cap portion 402 relatively. The upper end of the bottle body can be located within the spacing distance between the two flanges 212. The cap portion 402 is located in the receiving space 213 between the flange 212 and the pressing member 3. The flange 212 abuts against the edge of the cap portion 402 upward, and the pressing member 3 presses the cap portion 402 downward. The two flanges 212 and the pressing member 3 clamp the cap portion 402 up and down, and can pull out or insert the plug portion 401 into the bottle mouth through the cap portion 402. In this embodiment, the relative positions of the two clamping arms 211 can be fixed or can move relatively closer or farther away. For example, both of the two clamping arms 211 are fixed; or, one of the clamping arms 211 is movable and the other clamping arm 211 is fixed; or both of the two clamping arms 211 are movable.

[0062] In some embodiments, as Figure 1 shown, the bottle cap clamping member 2 further includes a first driving mechanism 22. The first driving mechanism 22 is arranged on the base body 1. The first driving mechanism 22 is drivingly connected with at least one clamping arm 211. The first driving mechanism 22 is used to drive the two clamping arms 211 to move relatively closer or farther away to clamp or loosen the cover body 40.

[0063] Specifically, the first driving mechanism 22 is a linear driving mechanism, which can specifically adopt a cylinder or a motor for driving, and is used to drive at least one clamping arm 211 to move closer to or away from another clamping arm 211. For example, the first driving mechanism 22 is a pneumatic claw, an electric claw or a combination of a motor and a lead screw. Figure 1 In the illustrated embodiment, the first driving mechanism 22 is a pneumatic claw, which simultaneously drives the two clamping arms 211 to open and close. Wherein, the moving direction of the clamping arm 211 is perpendicular to the first direction, that is, the clamping arm 211 moves in the horizontal direction.

[0064] In some embodiments, as Figure 1 shown, the pressing member 3 includes a pressing plate 31 and a pressing block 32 provided on the pressing plate 31. The pressing plate 31 is movably connected to the base body 1. The pressing block 32 is located on the side of the pressing plate 31 close to the first jaw 21, and the pressing block 32 is used to press the cover body 40.

[0065] Specifically, the pressing plate 31 can move relative to the base body 1 in the first direction (such as the up and down movement shown in Figure 1 ), thereby driving the pressing block 32 to move up and down. The pressing block 32 is located on the lower surface of the pressing plate 31. The upper end of the pressing block 32 is fixedly connected to the pressing plate 31. The lower end of the pressing block 32 is a free end and is used to press the cover body 40. The pressing plate 31 can be slidably connected to the base body 1. The pressing block 32 is arranged in the first direction (such as vertically arranged), and the pressing plate 31 is arranged in the second direction perpendicular to the first direction (such as horizontally arranged).

[0066] In some embodiments, as Figure 1 shown, the base body 1 includes a cross plate 11 arranged in the second direction (such as the horizontal direction) and a vertical plate 12 arranged in the first direction (such as the vertical direction). The cross plate 11 is perpendicular to the vertical plate 12. The cross plate 11 and the vertical plate 12 form an L shape. The first jaw 21 and the first driving mechanism 22 are arranged on the vertical plate 12, and the pressing member 3 is connected to the cross plate 11.

[0067] In some embodiments, the pressing block 32 is made of an elastic material and has a certain elasticity to prevent damage to the cover body 40. The elastic material can be rubber, silica gel, urethane rubber PU, etc. In some embodiments, an elastic material is provided on the surface of the pressing block 32 in contact with the cover body 40.

[0068] In some embodiments, both the first jaw 21 and the pressing block 32 are multiple, and the multiple pressing blocks 32 are arranged in one-to-one correspondence with the multiple first jaws 21. For example, both the first jaw 21 and the pressing block 32 can be two, three, four, or even more. Exemplarily, both the first jaw 21 and the pressing block 32 are three, and the lid opening and closing operations can be performed on three target bottles simultaneously, improving the experimental efficiency. Specifically, as Figure 1As shown, three pressing blocks 32 are provided on the pressing plate 31 , and there are three first clamping jaws 21 . The three pressing blocks 32 are arranged in a one-to-one correspondence with the three first clamping jaws 21 . The pressing plate 31 can drive the three pressing blocks 32 to move at the same time.

[0069] In some embodiments, the switch cover assembly further includes a first lifting mechanism, which is connected to the bottle cap clamp 2 and is used to drive the bottle cap clamp 2 to move along a first direction. Specifically, the first lifting mechanism can be in the form of a lifting cylinder, a combination of a motor and a screw rod, or a combination of a motor and a synchronous belt, thereby driving the bottle cap clamp 2 to move up and down. The upward movement of the bottle cap clamp 2 can separate the cover 40 from the bottle body, or can bring the cover 40 closer to the pressing member 3. When the bottle cap clamp 2 moves downward, the cover 40 can be inserted into the bottle body. The first lifting mechanism can be provided on the base 1 so that the bottle cap clamp 2 is slidably connected to the base 1.

[0070] In some embodiments, the switch cover assembly further includes a first lifting mechanism connected to the pressing member 3 and configured to drive the pressing member 3 to move in a first direction. Specifically, the first lifting mechanism drives the pressing member 3 to move up and down relative to the base 1, so that the pressing member 3 can abut against or separate from the cover 40. The first lifting mechanism can be disposed on the base 1 to provide a sliding connection between the pressing member 3 and the base 1.

[0071] In some embodiments, the switch cover assembly further comprises a first lifting mechanism, the first lifting mechanism being connected to the bottle cap clamp 2 and the pressing member 3, the first lifting mechanism being used to drive the bottle cap clamp 2 and the pressing member 3 to move in a first direction. Optionally, the first lifting mechanism may be provided on the base 1 so that the bottle cap clamp 2 and the pressing member 3 are both slidably connected to the base 1. Optionally, the first lifting mechanism may also be drivably connected to the base 1, the first lifting mechanism driving the base 1 to move in the first direction, thereby driving the bottle cap clamp 2 and the pressing member 3 on the base 1 to move. It is understandable that one first lifting mechanism may be provided, the bottle cap clamp 2 and the pressing member 3 being both connected to the first lifting mechanism, the first lifting mechanism being able to synchronously drive the bottle cap clamp 2 and the pressing member 3 to move up and down. Two first lifting mechanisms may be provided, the bottle cap clamp 2 and the pressing member 3 being respectively connected to the two first lifting mechanisms one-to-one, so as to achieve separate control of the movement of the bottle cap clamp 2 and the pressing member 3.

[0072] In some embodiments, as Figure 1 As shown, the switch cover assembly further includes an elastic member 4, which is disposed between the pressing member 3 and the base 1. Under the force of the elastic member 4, the pressing member 3 can move relative to the base 1 in a first direction and press against the end of the cover 40 facing away from the bottle body. One end of the elastic member 4 can be connected to the base 1, and the other end can be connected to the pressing member 3. The elastic member 4 can be a spring, a spring, a rubber column, a rubber block, etc.

[0073] Specifically, when the cover is opened or closed, the acting force of the elastic member 4 on the pressing member 3 is directed towards the cover body 40. The elastic member 4 can undergo elastic deformation in the first direction, and the pressing member 3 is movably connected to the base body 1 through the elastic member 4. As Figure 1 and Figure 2 shown, the acting force of the elastic member 4 on the pressing member 3 is downward, and the pressing member 3 presses downward on the upper surface of the cap portion 402. When opening the cover, the pressing member 3 presses downward on the cap portion 402 to prevent the cover body 40 from flying upward continuously after being pulled out of the bottle body. When closing the cover, the pressing member 3 presses downward on the cap portion 402 to press the plug portion 401 into the bottle body.

[0074] In some embodiments, as Figure 1 shown, the switch cover assembly further includes a guide post 5. The guide post 5 is arranged along the first direction. One of the base body 1 and the pressing member 3 is fixedly connected to one end of the guide post 5, and the other of the base body 1 and the pressing member 3 is movably connected to the other end of the guide post 5.

[0075] Specifically, the guide post 5 is used to guide the pressing member 3 when the pressing member 3 moves relative to the base body 1. The guide post 5 is arranged along the first direction, so as to guide the pressing member 3 to move relative to the base body 1 in the first direction. If the base body 1 is fixedly connected to one end of the guide post 5, the pressing member 3 is slidably connected to the other end of the guide post 5 in the first direction; if the pressing member 3 is fixedly connected to one end of the guide post 5, the base body 1 is slidably connected to the other end of the guide post 5 in the first direction. As Figure 1 shown, in the illustrated embodiment, the upper end of the guide post 5 is fixedly connected to the cross plate 11 of the base body 1, and the lower end of the guide post 5 is slidably connected to the pressing plate 31 of the pressing member 3. The pressing plate 31 can slide up and down along the guide post 5. There are four guide posts 5, which are respectively connected to the four corners of the pressing plate 31. The pressing plate 31 can be provided with linear bearings 33. The linear bearings 33 are sleeved on the guide posts 5, and the pressing plate 31 is slidably connected to the guide posts 5 through the linear bearings 33.

[0076] In some embodiments, as Figure 1 shown, the elastic member 4 is sleeved on the guide post 5. One end of the elastic member 4 abuts against the pressing member 3, and the other end of the elastic member 4 abuts against the base body 1. Specifically, the lower end of the elastic member 4 abuts against the pressing plate 31 of the pressing member 3, and the upper end of the elastic member 4 abuts against the cross plate 11 of the base body 1. The elastic member 4 is in a compressed state between the cross plate 11 and the pressing plate 31. Optionally, the elastic member 4 is a compression spring or a rubber sleeve, etc.

[0077] In some embodiments, as Figure 1 shown, the switch cover assembly further includes a position detection mechanism 6. The position detection mechanism 6 is arranged on the base body 1 and / or the pressing member 3. The position detection mechanism 6 is used to detect the position of the pressing member 3 relative to the base body 1.

[0078] Specifically, when the pressing member 3 moves to a predetermined position relative to the base 1, the position detection mechanism 6 is triggered, thereby controlling the pressing member 3 to continue or stop moving relative to the base 1 according to the detection signal of the position detection mechanism 6. For example, when the pressing member 3 presses down on the cover 40, the pressing member 3 moves upward relative to the base 1 and compresses the elastic member 4 until the pressing member 3 moves upward to trigger the position detection mechanism 6, at which point the pressing member 3 and the base 1 stop moving relative to each other. This allows the compression amount of the elastic member 4 to be controlled according to the position detection mechanism 6, thereby controlling the pressure exerted by the pressing member 3 on the cover 40 and ensuring that the cover 40 is pressed tightly against the bottle body. By jointly controlling the closing force of the cover by the pressing member 3 and the position detection mechanism 6, the cover 40 will not be loosely closed due to insufficient force, nor will the cover 40 be damaged or the connection between the cover 40 and the bottle body be too tight due to excessive force, making it difficult to open the bottle the next time. The position detection mechanism 6 includes a photoelectric sensor and a sensing sheet, one of which is disposed on the base 1 and the other on the pressing member 3, thereby detecting the position of the pressing member 3 relative to the base 1. It is understood that the position detection mechanism 6 may also be other structures, such as a distance sensor, which is not limited here.

[0080] like Figures 3 to 5 As shown, the embodiment of the present application further provides a cover opening and closing device, including the cover opening and closing assembly as described in the above embodiment. Here, the target bottle is a volumetric flask as an example for description, and the volumetric flask has a bottle body 30 and a cover body 40.

[0081] In some embodiments, as Figures 3 to 5 As shown, the cover opening and closing device further includes a bottle clamp 7, which is located on the side of the first clamping jaw 21 facing away from the pressing member 3. The bottle clamp 7 is used to secure the bottle 30. The structure of the bottle clamp 7 is not limited and can be a holder mechanism for securing the bottle 30, or a clamp mechanism for clamping the bottle 30.

[0082] In some embodiments, the bottle body clamping member 7 includes a second clamping jaw 71 and a second driving mechanism 72 drivingly connected to the second clamping jaw 71 . The second driving mechanism 72 is used to drive the second clamping jaw 71 to open and close to clamp or release the bottle body 30 of the target bottle.

[0083] Specifically, the bottle clamping member 7 is located below the switch cover assembly. The second clamping jaw 71 can clamp the bottleneck part of the bottle 30 when opening and closing the cover, maintaining the stability of the bottle 30, thereby preventing the bottle 30 from being lifted when opening the cover and preventing the bottle 30 from shaking when closing the cover. The second driving mechanism 72 can be a pneumatic claw or an electric claw. Figures 3 to 5 In the illustrated embodiment, the second driving mechanism 72 is a pneumatic claw.

[0084] In some embodiments, both the first clamping jaw 21 and the second clamping jaw 71 are multiple. The multiple first clamping jaws 21 and the multiple second clamping jaws 71 are arranged in one-to-one correspondence, enabling the cover opening and closing device to perform cover opening and closing operations on multiple target bottles simultaneously, thereby improving the cover opening and closing efficiency. It can be understood that when multiple first clamping jaws 21 are provided, multiple first driving mechanisms 22 are also provided. The multiple first driving mechanisms 22 are connected to the multiple first clamping jaws 21 in one-to-one correspondence, and each first clamping jaw 21 can be independently controlled to open and close; alternatively, only one first driving mechanism 22 is provided, and the multiple first clamping jaws 21 are all connected to the first driving mechanism 22, such that the multiple first clamping jaws 21 are synchronously controlled to open and close by the first driving mechanism 22. Similarly, when multiple second clamping jaws 71 are provided, multiple second driving mechanisms 72 are also provided. The multiple second driving mechanisms 72 are connected to the multiple second clamping jaws 71 in one-to-one correspondence, and each second clamping jaw 71 can be independently controlled to open and close; alternatively, only one second driving mechanism 72 is provided, and the multiple second clamping jaws 71 are connected to the second driving mechanism 72, such that the multiple second clamping jaws 71 are synchronously controlled to open and close by the second driving mechanism 72.

[0085] In some embodiments, as Figures 3 to 5 shown, the cover opening and closing device further includes a bracket 8. The bottle clamping member 7 and the switch cover assembly are both slidably connected to the bracket 8. Specifically, the bottle clamping member 7 and the switch cover assembly are both slidably connected to the bracket 8 in a first direction. When opening the cover, the switch cover assembly can move upward relative to the bracket 8 to pull out the cover body 40 from the bottle 30; when closing the cover, the switch cover assembly can move downward relative to the bracket 8 to press the cover body 40 into the bottle 30. The bottle clamping member 7 can make the second clamping jaw 71 clamp different parts of the bottle 30 through the sliding connection with the bracket 8. For target bottles of different models, the bottle clamping member 7 can move up and down relative to the bracket 8 to adapt to the height of the corresponding target bottle. Therefore, the bottle clamping member 7 and the switch cover assembly are both slidably connected to the bracket 8 in the first direction, enabling the cover opening and closing device to perform cover opening and closing on multiple target bottles of different models, improving the versatility of the device. Among them, a guide rail can be arranged on the bracket 8 along the first direction, and the bottle clamping member 7 and the switch cover assembly can slide along the guide rail.

[0086] In some embodiments, the bottle clamping member 7 or the switch cover assembly is slidably connected to the bracket 8, that is, one of the bottle clamping member 7 and the switch cover assembly is slidably connected to the bracket 8, and the other may be fixedly connected to the bracket 8. In this way, only one of the bottle clamping member 7 and the switch cover assembly needs to be moved up and down relative to the bracket 8.

[0087] In some embodiments, as Figures 3 to 5 shown, the bracket 8 includes a first bracket 81 and a second bracket 82. The first bracket 81 is perpendicular to the second bracket 82. The first bracket 81 extends along the first direction, and the second bracket 82 extends along a second direction perpendicular to the first direction, that is, the first bracket 81 is vertically arranged and the second bracket 82 is horizontally arranged. The bottle clamping member 7 and the switch cover assembly are both arranged on the first bracket 81, and both the bottle clamping member 7 and the switch cover assembly can move relative to the first bracket 81 in the first direction. The second bracket 82 is provided with a placement table 9 for placing the target bottle. The placement table 9 is located on the side of the second jaw 71 away from the first jaw 21, that is, the placement table 9 is located below the second jaw 71 and is used to support the bottom of the bottle body 30, so as to reduce the load of the bottle clamping member 7. Among them, the number of the placement tables 9 may be the same as the number of the second jaws 71.

[0088] Specifically, as Figures 3 to 5 shown, the switch cover device has three placement tables 9. Correspondingly, the bottle clamping member 7 has three second jaws 71, and the bottle cap clamping member 2 has three first jaws 21. The switch cover device can perform the switch cover operation on three target bottles at the same time, thereby improving the experimental efficiency.

[0089] In some embodiments, one of the bottle clamping member 7 or the switch cover assembly can move relative to the first bracket 81 in the first direction, and the other is fixed relative to the first bracket 81, and the switch cover operation can also be realized.

[0090] In some embodiments, as Figures 3 to 5 shown, the switch cover device further includes a second lifting mechanism 10. The second lifting mechanism 10 is arranged on the bracket 8 and is drivingly connected to the bottle clamping member 7. The second lifting mechanism 10 is used to drive the bottle clamping member 7 to move along the first direction. Specifically, the second lifting mechanism 10 may be a combination of a motor and a lead screw. The motor is connected to the bottle clamping member 7 through the lead screw, so as to drive the bottle clamping member 7 to move up and down. It can be understood that the second lifting mechanism 10 can also be driven by a cylinder, which is not limited herein.

[0091] In some embodiments, as Figures 3 to 5 shown, the switch cover assembly further includes a third lifting mechanism 20. The third lifting mechanism 20 is arranged on the bracket 8 and is drivingly connected to the base body 1. The third lifting mechanism 20 is used to drive the base body 1 to move along the first direction to drive the bottle cap clamping member 2 and the pressing member 3 to move along the first direction.

[0092] Specifically, the third lifting mechanism 20 can be a combination of a motor and a lead screw. The motor is connected to the base body 1 through the lead screw, so as to drive the bottle cap clamping member 2 and the pressing member 3 to move up and down. Similarly, the third lifting mechanism 20 can also be driven by a cylinder, which is not limited herein.

[0093] In some embodiments, as Figures 3 to 5 shown, the switch cap device further includes a solenoid valve assembly 50. When both the first driving mechanism 22 and the second driving mechanism 72 are air grippers, the solenoid valve assembly 50 is respectively communicated with the first driving mechanism 22 and the second driving mechanism 72 through air pipes, and controls the on-off of the gas input to the first driving mechanism 22 and the second driving mechanism 72, so as to control the opening and closing of the first jaw 21 and the second jaw 71.
