[0050] With reference to the accompanying drawings, the technical solutions in the embodiments will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort are within the protection scope of the present application.

[0051] It should be noted that all the direction indications (such as up, down, left, right, front, back, and the like) in the embodiments are merely used to explain the relative position relationship and movement condition between components in a certain posture (as shown in the drawings), and if the certain posture changes, the direction indications also change accordingly.

[0052] In addition, the descriptions such as “first”, “second” and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as “first” and “second” can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of “plurality” is at least two, for example, two, three, and the like, unless otherwise specifically limited.

[0053] In the present application, unless otherwise specifically defined and limited, the terms “connection”, “fixation” and the like should be understood in a broad sense, for example, “fixation” can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise specifically limited.

[0054] In addition, the technical solutions of the various embodiments of the present application can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the protection scope of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application, and not to limit the present application.

[0055] In the present application, the description of “up”, “down”, “front”, “back”, “left”, “right” and the like is based on the orientation shown in the drawings, and is only used to explain the relative position relationship between components in the posture shown in the drawings, and if the certain posture changes, the direction indications also change accordingly.

[0056] At present, from the development of market situation, the application of power battery is more and more widely. Power battery is not only applied to the energy storage power supply system of water power, fire power, wind power and solar power station, but also widely used in electric bicycle, electric motorcycle, electric vehicle and other electric vehicles, and aerospace and other fields. With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0057] In the process of manufacturing the battery device, a large number of sample containers are involved in the opening and closing operation of the cover in chemical synthesis, drug synthesis and biochemical experiments. The sample tubes commonly involved in the experiment include blue mouth bottles, flasks, syringes and reagent bottles. The sample can be electrolyte, mixed material for making pole piece or other products. The sample is generally placed in the sample tube, which includes a bottle body and a bottle cap arranged on the bottle body. During the experiment, the bottle cap is often opened for extracting the sample inside.

[0058] However, the current automatic opening mechanism generally sets a clamping assembly at the bottom to clamp the bottle body of the sample tube, and then clamps the bottle cap through the upper opening clamp. After clamping the bottle cap, the bottle cap is removed from the bottle body by rotating. Such opening structure can basically meet the requirements in some cases, but in some cases, it is difficult to open the bottle cap or the bottle cap is easily damaged.

[0059] The applicant found through careful research that the current opening mechanism can basically meet the needs when opening the sample tube for the cylindrical bottle cap or the bottle cap with small taper. However, as the types of sample tubes are increasing, some sample tubes with conical bottle caps appear. For the bottle caps of these sample tubes, the clamping area of the opening clamp of the opening mechanism and the bottle cap is small. In order to keep the clamping jaw clamping the bottle cap during the opening process, the clamping force of the clamping jaw needs to be increased. For the bottle cap made of soft material such as wood, rubber or glass with small thickness, there is a risk of damaging the bottle cap due to excessive clamping force. Therefore, due to the small stress area and the fact that the clamping force cannot be designed too large, the clamping jaw cannot clamp the bottle cap, the clamping jaw cannot rotate or stretch the bottle cap together, which makes it difficult to open the bottle cap.

[0060] To this end, the applicant provides a new structure design of the cap opening clamp, which comprises a base, a first driving member, a second driving member and a clamping assembly. The output shaft of the first driving member is connected with the base, and the second driving member is installed on the base. The clamping assembly comprises a plurality of clamping claws, which are arranged to form a clamping space for clamping the bottle cap. Each clamping claw is arranged to be inclined towards the clamping space. The second driving member is connected with each clamping claw to drive the plurality of clamping claws to clamp or loosen the bottle cap. By arranging the clamping assembly to comprise a plurality of clamping claws, the plurality of clamping claws are arranged to form a clamping space for clamping the bottle cap, and each clamping claw is arranged to be inclined towards the clamping space, so that the conical bottle cap is clamped conveniently, and the application range of the cap opening clamp to the shape of the bottle cap is improved.

[0061] With reference to Figure 1 According to some embodiments of the present application, the present application provides a cap opening clamp 100, which comprises a base 10, a first driving member 20, a second driving member 30 and a clamping assembly. The output shaft of the first driving member 20 is connected with the base 10, and the second driving member 30 is installed on the base 10. The clamping assembly comprises a plurality of clamping claws 40, which are arranged to form a clamping space 50 for clamping the bottle cap 2100. Each clamping claw 40 is arranged to be inclined towards the clamping space 50. The second driving member 30 is connected with each clamping claw 40 to drive the plurality of clamping claws 40 to clamp or loosen the bottle cap 2100.

[0062] It should be noted that the cap opening clamp 100 of the embodiments of the present application is applied to a cap opening mechanism 1000, which is applied to the cap opening operation of the sample tube 2000, and of course can also be the cap closing operation. With reference to Figure 7 The cap opening mechanism 1000 further comprises a clamping assembly 200 and a bracket 500. The bracket 500 is installed on the platform surface, and the cap opening clamp 100 is installed on the bracket 500. The cap opening clamp 100 can be movably installed on the bracket 500, so as to facilitate the adjustment of the position of the cap opening clamp 100. The clamping assembly 200 is arranged below the cap opening clamp 100, and is used to clamp the bottle body 2200 of the sample tube 2000. The cap opening clamp 100 is used to clamp the bottle cap 2100 of the sample tube 2000, and can provide a rotating torque or a stretching force to take out the bottle cap 2100 from the bottle body 2200.

[0063] In the above embodiments of the present application, the clamping assembly includes a plurality of clamping jaws 40, which are arranged to form a clamping space 50 for clamping the bottle cap 2100, and are respectively connected with the second driving member 30 to be capable of moving towards the bottle cap 2100 while approaching or separating from each other under the driving action of the second driving member 30, so as to clamp the bottle cap when approaching each other, and to prepare for uncapping. After uncapping is completed, the second driving member 30 can drive each clamping jaw 40 to rise and move away from each other to release the removed bottle cap 2100. The plurality of clamping jaws 40 are arranged to form the clamping space 50 in the middle, and the bottle cap 2100 is located in the clamping space 50. After the second driving member 30 drives the clamping jaws 40 to clamp the bottle cap 2100, the first driving member 20 starts to work, and the first driving member 20 transmits torque to the clamping jaws 40 by driving the base 10 to move. For example, the first driving member 20 can rotate to drive the base 10 to rotate, so as to rotate the clamping jaws 40 to unscrew the bottle cap 2100. The second driving member 30 can also drive the base 10 to move by stretching and contracting, and then make the clamping jaws 40 retract towards the base 10 to remove the bottle cap 2100. By arranging the clamping jaws 40 to be inclined towards the clamping space 50, that is, the plurality of clamping jaws 40 are arranged to be inclined relative to the vertical direction and have a certain angle with the vertical direction, so that the plurality of clamping jaws 40 form a conical clamping space 50 to adapt to the clamping of the conical bottle cap 2100, so that each clamping jaw 40 has a larger contact area with the outer periphery of the conical bottle cap 2100, and the bottle cap 2100 can be clamped more stably, which is convenient for the second driving member 30 to remove the bottle cap 2100. In some possible embodiments, the angle of the clamping jaw 40 relative to the vertical direction can be 10°-20°, for example, it can be 10°, 12°, 14°, 15°, 16°, 18° or 20°, and the like. Of course, those skilled in the art can understand that the above examples are only to illustrate an optional embodiment of the present application, and the range of the angle value is not limited.

[0064] By arranging the clamping assembly to include a plurality of clamping jaws 40, which are arranged to form a clamping space 50 for clamping the bottle cap 2100, and each clamping jaw 40 is arranged to be inclined towards the clamping space 50, the conical bottle cap 2100 is clamped, and the application range of the uncapping clamp 100 to the shape of the bottle cap 2100 is improved.

[0065] Referring to Figure 2 and Figure 3 In some embodiments, the second driving member 30 includes a telescopic motor 31 and a plurality of movable rods 32, the telescopic motor 31 includes a body 311 and a telescopic part 312 connected with the body 311 in a telescopic manner, the body 311 is installed on the base 10, the two ends of each movable rod 32 are respectively connected with the telescopic part 312 and the base 10, and the plurality of clamping jaws 40 are connected with the plurality of movable rods 32 in a one-to-one correspondence.

[0066] The telescopic motor 31 refers to a motor that can be driven to linearly extend and retract. Of course, the telescopic motor 31 can also be replaced by a pneumatic cylinder. The body 311 refers to the cylinder body of the telescopic motor 31. The body 311 is mounted on the base 10. The telescopic part 312 can move linearly relative to the body 311. The two ends of the movable rod 32 are connected to the telescopic part 312 and the base 10, respectively. The movable rod 32 can be driven to extend and retract or rotate by the telescopic part 312. The number of movable rods 32 is multiple, and the number of clamping jaws 40 is also multiple. The movable rod 32 is connected to the clamping jaw 40 one by one. Thus, the movable rod 32 moves under the drive of the telescopic part 312, which can drive the clamping jaw 40 connected thereto to move. When the bottle cap 2100 needs to be clamped, the telescopic part 312 is extended to indirectly drive the clamping jaw 40 to move towards the sample tube 2000 to clamp the bottle cap 2100. After clamping is completed, the telescopic part 312 can also be retracted to retract the clamping jaw 40.

[0067] By providing the second driving member 30 including the telescopic motor 31 and the movable rod 32, the telescopic part 312 is used to drive the movable rod 32 to move, and the movable rod 32 is used to drive the clamping jaw 40 to move. Thus, the multiple clamping jaws 40 can clamp or release the bottle cap 2100 of the sample tube 2000.

[0068] With reference to Figure 2 and Figure 3 In some embodiments, each movable rod 32 includes a first sub-rod 321 and a second sub-rod 322 that are hingedly connected to each other. The first sub-rod 321 is hingedly connected to the base 10 at an end away from the second sub-rod 322. The second sub-rod 322 is hingedly connected to the telescopic part 312 at an end away from the first sub-rod 321. The clamping jaw 40 is connected to the second sub-rod 322.

[0069] At this time, the movable rod 32 is connected by the two hingedly connected first sub-rod 321 and second sub-rod 322. The first sub-rod 321 and the second sub-rod 322 are arranged at an angle. The second sub-rod 322 can rotate relative to the first sub-rod 321. Meanwhile, the first sub-rod 321 is hingedly connected to the base 10 and can rotate relative to the base 10. The second sub-rod 322 is also hingedly connected to the telescopic part 312. When the telescopic part 312 extends towards the sample tube 2000, the telescopic part 312 drives the second sub-rod 322 to move, so that the second sub-rod 322 rotates relative to the first sub-rod 321. The first sub-rod 321 and the second sub-rod 322 are relatively straightened, so that the clamping jaw 40 moves towards the bottle cap 2100. At this time, since the second sub-rod 322 is rotating, the movement of the clamping jaw 40 mounted on the second sub-rod 322 is not vertical downward, but has an inclination towards the clamping space 50. Therefore, the spacing between the clamping jaws 40 is reduced. Thus, after the bottle cap 2100 is located in the clamping space 50, the movement of the telescopic part 312 can make the multiple clamping jaws 40 closer, which is conducive to clamping the bottle cap 2100.

[0070] By setting the active rod 32 to include the hingedly connected first sub-rod 321 and the second sub-rod 322, the first sub-rod 321 is hingedly connected with the base 10, and the second sub-rod 322 is hingedly connected with the telescopic part 312, which can drive the second sub-rod 322 to rotate relative to the first sub-rod 321 while the second sub-rod 322 moves downward during the linear telescoping of the telescopic part 312, and further make the clamping jaw 40 move downward to clamp the bottle cap 2100.

[0071] Referring to Figure 2 and Figure 3 In some embodiments, the telescopic part 312 includes a telescopic shaft 3121 telescopically connected with the body 311 and a disc 3122 mounted on the telescopic shaft 3121, a plurality of second sub-rods 322 are spaced apart around the disc 3122 and are hingedly connected with the disc 3122, and the number of the second sub-rods 322 and the clamping jaws 40 is equal and one-to-one correspondence.

[0072] The telescopic shaft 3121 is the output shaft of the telescopic motor 31, which is generally rod-shaped, and the disc 3122 is sleeved on the telescopic shaft 3121, which is generally fixedly mounted. The telescopic shaft 3121 can move along the central axis of the telescopic shaft 3121 under the drive of the body 311. A plurality of second sub-rods 322 are hingedly connected with the outer periphery of the disc 3122. Specifically, the plurality of second sub-rods 322 can be uniformly distributed around the outer periphery of the disc 3122, which is uniformly distributed around the central axis of the telescopic shaft 3121. Each second sub-rod 322 is provided with a clamping jaw 40, so that each clamping jaw 40 is also uniformly distributed around the central axis of the telescopic shaft 3121. This can make the clamping jaw 40 uniformly clamp the bottle cap 2100 from each position in the clamping space 50, so that the bottle cap 2100 is uniformly stressed, facilitating clamping of the bottle cap 2100.

[0073] By setting a plurality of second sub-rods 322 to be spaced apart around the disc 3122, the second sub-rods 322 and the clamping jaws 40 are one-to-one correspondence, and a plurality of clamping jaws 40 are uniformly distributed around the central axis of the telescopic shaft 3121. When the bottle cap 2100 is arranged in the clamping space 50, the positions of the clamping jaws 40 clamping the bottle cap 2100 are also uniformly distributed, which is beneficial to the uniform stress of the bottle cap 2100, facilitating clamping of the bottle cap 2100.

[0074] Referring to Figure 2 and Figure 3 In some embodiments, the plurality of clamping jaws 40 are inclined from the second sub-rod 322 to the direction close to the central axis of the telescopic shaft 3121, so that the plurality of clamping jaws 40 surround the clamping space 50 which is tapered in the direction away from the second sub-rod 322.

[0075] After the uncapping clamp 100 is installed on the uncapping mechanism 1000, the central axis of the telescopic shaft 3121 is actually vertical, and the plurality of clamping jaws 40 are arranged downwardly and obliquely toward the central axis from the second sub-shaft 322, forming a clamping space 50 which is a conical space with a small lower bottom circle and a large upper bottom circle, and most of the conical bottle caps 2100 are also conical caps with a small lower bottom circle and a large upper bottom circle, so that the clamping of the conical bottle cap 2100 can be more suitable.

[0076] With reference to Figure 2 and Figure 4 In some embodiments, the clamping jaw 40 comprises a first clamping block 41 and a second clamping block 42 which are hingedly connected to each other, the first clamping block 41 is connected to the corresponding second sub-shaft 322, and each second clamping block 42 is arranged obliquely toward the clamping space 50.

[0077] The hingedly connected first clamping block 41 and the second clamping block 42 means that the second clamping block 42 can rotate around the first clamping block 41, the first clamping block 41 is installed on the corresponding second sub-shaft 322, and the connection here can be a fixed connection, the second clamping block 42 is arranged at one end of the first clamping block 41 away from the second clamping block 42, and the second clamping block 42 is arranged obliquely toward the clamping space 50, and specifically, the second clamping block 42 is used to clamp the bottle cap 2100. Because the tapers of different bottle caps 2100 are not exactly the same, and even the same type of bottle cap 2100 has a production tolerance, or may have wear during use, resulting in a size difference, the actual bottle cap 2100 may not be as ideal as the bottle cap 2100 that meets the standard, which may cause the second clamping block 42 to not be able to clamp the bottle cap 2100 well. Therefore, the second clamping block 42 is arranged to be rotatable relative to the first clamping block 41, so that when there is a small size deviation, the size of the clamping space 50 can be adjusted by rotating the second clamping block 42 to clamp the bottle cap 2100. At the same time, the second clamping block 42 can also be used for different taper conical bottle caps 2100 by rotating the second clamping block 42.

[0078] By arranging the clamping jaw 40 to comprise a first clamping block 41 and a second clamping block 42 which are hingedly connected to each other, the first clamping block 41 is installed on the second sub-shaft 322, and the second clamping block 42 is used to clamp the bottle cap 2100, and the second clamping block 42 is arranged to be rotatable relative to the first clamping block 41, so that it can be used for bottle caps 2100 with size deviations, and at the same time, by adjusting the position of the second clamping block 42, it can also be used for bottle caps 2100 with different tapers, greatly improving the range of application of the uncapping clamp 100 to bottle caps 2100 with different tapers.

[0079] With reference to Figure 4 and Figure 5In some embodiments, the first clamping block 41 and the second clamping block 42 are hinged by a hinge shaft 43, the hinge shaft 43 is sleeved with a torsion spring 44, and the two torsion arms of the torsion spring 44 are respectively connected with the first clamping block 41 and the second clamping block 42.

[0080] The torsion spring 44 can include a spring body 441 and two torsion arms, which can be a first torsion arm 442 and a second torsion arm 443 respectively, the first torsion arm 442 is connected with the first clamping block 41, and the second torsion arm 443 is connected with the second clamping block 42. The torsion spring 44 can be used to provide a restoring force and limit the rotation angle of the second clamping block 42. Specifically, when the second clamping block 42 approaches the tapered bottle cap 2100, the second clamping block 42 will rotate due to the size of the tapered bottle cap 2100 being larger at the top and smaller at the bottom. When rotating, the second torsion arm 443 deforms to store energy, and there is an elastic restoring force. When the second clamping block 42 moves to the lower part of the bottle cap 2100 with smaller size, it will move towards the bottle cap 2100 under the drive of the elastic restoring force to clamp the tapered surface. In this way, the stability of the clamping jaw 40 clamping the bottle cap 2100 can be improved. At the same time, the deformation of the torsion spring 44 has a certain range, which can reduce the risk of damage to the hinge shaft 43 and the second clamping block 42 due to the rotation of the second clamping block 42 exceeding the preset limit.

[0081] By sleeving the torsion spring 44 on the hinge shaft 43, and connecting the two torsion arms of the torsion spring 44 with the first clamping block 41 and the second clamping block 42 respectively, the tapered bottle cap 2100 can be clamped stably, and the risk of damage to the second clamping block 42 due to excessive rotation can be reduced.

[0082] Referring to Figure 4 and Figure 5 In some embodiments, the first clamping block 41 is spaced apart from two hinge ears, a gap 411 is arranged between the two hinge ears, the second clamping block 42 partially extends into the gap 411 and is installed on the hinge shaft 43, both ends of the hinge shaft 43 extend out of the two hinge ears, and the two ends of the hinge shaft 43 extending out of the hinge ears are respectively provided with a limiting piece 45.

[0083] The two hinge ears can be two protruding plate bodies, the plate bodies are provided with through holes for the hinge shaft 43 to pass through, the hinge shaft 43 enters from one through hole, passes through the gap 411 and extends out from the other through hole, the second clamping block 42 partially extends into the gap 411 and is installed on the part of the hinge shaft 43 in the gap 411, both ends of the hinge shaft 43 are arranged outside the two hinge ears, and the hinge shaft 43 is provided with a clamping groove at the part outside the hinge ears, the limiting piece 45 can be a clamping ring, the limiting piece 45 is arranged in the clamping groove, and the limiting piece 45 can be used to abut against the hinge ear to reduce the risk of the first clamping block 41 and the second clamping block 42 falling off.

[0084] By setting the hinge shaft 43 to pass through the two hinge ears, and setting the limiting piece 45 at both ends of the hinge shaft 43, the risk of the first clamp block 41 and the second clamp block 42 falling off can be reduced.

[0085] With reference to Figure 6 In some embodiments, the second clamp block 42 is provided with a buffer pad 46 on one side facing the clamping space 50, and the buffer pad 46 is provided with anti-skid marks 461.

[0086] The second clamp block 42 has a clamping surface, which is a surface on one side facing the clamping space 50 for clamping the bottle cap 2100. The buffer pad 46 provided on the clamping surface plays a buffering role, reducing the risk of damage to the bottle cap 2100 due to excessive instantaneous pressure. The buffer pad 46 is generally made of rubber pad or foam pad, and the anti-skid marks 461 in the form of protrusions or recesses can be provided on the buffer pad 46 to reduce the risk of slipping of the bottle cap 2100 relative to the second clamp block 42.

[0087] By providing the buffer pad 46 on the second clamp block 42, the risk of damage to the bottle cap 2100 due to excessive instantaneous pressure can be reduced, and by providing the anti-skid marks 461 on the buffer pad 46, the risk of unstable clamping due to relative sliding of the bottle cap 2100 relative to the second clamp block 42 can be reduced.
