[0028] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0030] Based on this situation, the embodiment of the present application provides a flexible cutting device for an ampoule bottle. Figures 1 to 4 , the flexible cutting device for ampoule provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0031] See Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application discloses a flexible ampoule cutting device, which includes an electric clamp 100, a bracket 200, an elastic floating mechanism 300 and a cutting blade 400, wherein two brackets 200 are connected to the electric clamp 100, and the two brackets 200 are arranged opposite to each other to define an accommodating space therebetween, and the ampoule 700 can be accommodated in the accommodating space. The electric clamp 100 has an open state and a clamping state. In the open state, the ampoule 700 can be extended into the accommodating space. In the clamping state, the electric clamp 100 can clamp the ampoule 700 through the two brackets 200.

[0032] In an embodiment of the present application, the bracket 200 is connected to the cutting blade 400 through an elastic floating mechanism 300. The elastic floating mechanism 300 applies an elastic force to the cutting blade 400, so that the cutting blade 400 abuts against the outer wall of the ampoule bottle 700 to clamp the ampoule bottle 700. When cutting, the electric clamp 100 drives the bracket 200 to rotate, so that the cutting blade 400 rotates around the circumference of the ampoule bottle 700 while abutting against the outer wall of the ampoule bottle 700 to cut the ampoule bottle 700. For example, the cutting blade 400 can abut against the bottleneck of the ampoule bottle 700 to cut the ampoule bottle 700 at the bottleneck.

[0033] Based on the above technical solution, the cutting blade 400 is abutted against the outer wall of the ampoule bottle 700 through the elastic floating mechanism 300, and the electric clamp 100 can drive the bracket 200 to rotate to achieve cutting of the ampoule bottle 700. Based on the elastic force applied to the cutting blade 400 by the elastic floating mechanism 300, flexible contact between the cutting blade 400 and the ampoule bottle 700 can be achieved, and the abutment force can be controlled more accurately, effectively reducing the cutting error, ensuring the consistency and accuracy of the cutting of the ampoule bottle 700, thereby reducing the breakage rate of the ampoule bottle 700, and improving the efficiency of opening the bottle and dispensing medicine while ensuring the safety of the operator.

[0034] At the same time, based on the floating characteristics of the elastic floating mechanism 300 in the direction of its force application, when the electric clamp 100 is in a clamped state, the accommodating space can also accommodate ampoules 700 of different sizes, that is, the flexible cutting device for ampoule bottles of the embodiment of the present application can realize the cutting of ampoules 700 of different sizes, thereby improving the versatility of the flexible cutting device for ampoule bottles.

[0035] In the examples of this application, see Figure 2 and Figure 3 The two brackets 200 are arranged opposite to each other, so that the two cutting blades 400 are symmetrically distributed on both sides of the ampoule bottle 700. The symmetrically distributed cutting blades 400 can ensure that the ampoule bottle 700 is subjected to uniform cutting force during the cutting process, thereby reducing the problem of bottle mouth breakage or uneven cutting caused by uneven force.

[0036] In the examples of this application, see Figure 3 The elastic floating mechanism 300 includes an elastic member 310 and a slider 320, wherein the slider 320 slides along a first direction to fit with the bracket 200, and the cutting piece 400 is provided on the slider 320. For example, the cutting piece 400 can be connected and fixed to the slider 320 by a threaded connection. The first direction is the relative direction of the two brackets 200, that is, when each bracket 200 is facing the ampoule bottle 700. The elastic member 310 can be a compression spring, one end of the elastic member 310 is against the bracket 200, and the other end of the elastic member 310 is against the slider 320.

[0037] Based on the above technical solution, when the electric clamp 100 is in the open state, the elastic member 310 is in the natural state. At this time, there is a large gap between the two cutting blades 400 for the ampoule bottle 700 to penetrate into the accommodating space. In the process of the electric clamp 100 switching from the open state to the clamped state, the two cutting blades 400 approach each other and abut against the outer wall of the ampoule bottle 700. At this time, the slider 320 slides relative to the bracket 200 and compresses the elastic member 310. It can be understood that when the sizes of the ampoule bottles 700 are different, the compression deformation of the elastic member 310 is not the same, that is, the elastic member 310 has a certain deformation range in the first direction so as to be able to adapt to ampoules 700 of different sizes.

[0038] In the examples of this application, see Figure 1 and Figure 3 The bracket 200 includes a bracket base 210, which is connected to the electric gripper 100 and serves as a mounting base for the elastic floating mechanism 300 and the cutting blade 400. Specifically, the bracket base 210 is provided with a slide groove 2131 extending along a first direction. The slider 320 slidably fits within the slide groove 2131. The central axis of the cutting blade 400 is connected to the slider 320, and the cutting blade 400 can slide along the slider 320.

[0039] In a further technical solution, the slide groove 2131 is set to penetrate along the longitudinal direction, the bracket base 210 is provided with a step 2132 in the slide groove 2131, the slider 320 slides in the slide groove 2131, and the slider 320 is supported on the step 2132, and the cutting blade 400 is connected to the bottom of the slider 320.

[0040] In an embodiment of the present application, the slide groove 2131 can penetrate the bracket base 210 in the first direction to facilitate the processing and forming of the slide groove 2131 on the bracket base 210. Based on this situation, the bracket 200 can also include a first baffle 220, and the first baffle 220 is connected and fixed to the bracket base 210. For example, the first baffle 220 can be connected and fixed to the bracket base 210 using a threaded connector. The first baffle 220 is located at one end of the slide groove 2131 close to the ampoule bottle 700. Along the first direction, the first baffle 220 is limited by the slider 320. The first baffle 220 can prevent the slider 320 from sliding away from the bracket base 210 along the first direction.

[0041] In a further technical solution, the first baffle 220 includes a mounting portion 221 and a limiting portion 222, and the mounting portion 221 and the limiting portion 222 are connected to make the first baffle 220 L-shaped. For example, the first baffle 220 can be integrally stamped from a plate-like structure to form the aforementioned mounting portion 221 and limiting portion 222. The mounting portion 221 is located above the limiting portion 222, and the threaded connector passes through the mounting portion 221 and is connected and fixed to the bracket base 210. The limiting portion 222 is limitedly cooperated with the slider 320 to prevent the slider 320 from sliding away from the bracket base 210 along the first direction. The mounting portion 221 is arranged above the limiting portion 222 to realize the connection and fixation of the first baffle 220 with the bracket base 210, which can avoid the threaded connector interfering with the contact with the cutting blade 400 or the ampoule bottle 700, so that the cutting blade 400 can stably contact the ampoule bottle 700 and play a cutting role.

[0042] In some embodiments of the present application, the bracket 200 may also include a second baffle 230, which is fixedly connected to the bracket base 210. Along the second direction, the second baffle 230 is limitedly engaged with the slider 320 to prevent the slider 320 from sliding away from the bracket base 210 along the second direction. The second direction is the direction in which the two brackets 200 are opposite to each other, that is, when each bracket 200 is facing the ampoule bottle 700.

[0043] In a further technical solution, a first cavity is provided on the slider 320, and a second cavity is provided on the second baffle 230. The two ends of the elastic member 310 are respectively accommodated in the first cavity and the second cavity. The first cavity and the second cavity can play a positioning role for the elastic member 310 to prevent the elastic member 310 from being offset or misplaced.

[0044] In the aforementioned embodiment, the slide groove 2131 penetrates the support base 210 in the first direction and the second direction, so it is necessary to respectively provide a first stopper 220 and a second stopper 230 at both ends of the slide groove 2131 to prevent the slider 320 from sliding off the support base 210. In some embodiments of the present application, the slide groove 2131 may also be provided on the support base 210 in a non-throughgoing manner. In this case, the slider 320 can be limited by the inner wall of the slide groove 2131 to prevent it from sliding off the slide groove 2131.

[0045] In the examples of this application, see Figure 2 、 Figure 3 and Figure 4The bracket base 210 includes a first connecting section 211, an extension section 212 and a second connecting section 213. The first connecting section 211, the extension section 212 and the second connecting section 213 are connected in sequence to make the bracket base 210 in a U shape, wherein the first connecting section 211 is connected to the electric clamp 100, the extension section 212 is extended in the longitudinal direction, and the elastic floating mechanism 300 is provided on the second connecting section 213. Based on the extension effect of the extension section 212 in the longitudinal direction, the bracket 200 can form the aforementioned accommodating space. The bracket base 210 adopts this design method, which has the characteristics of clever structure and convenient production and assembly.

[0046] During the research process, the inventors also found that the heights of ampoules 700 of different sizes are not the same, and the cutting position of the ampoule 700 is usually at its bottleneck. Based on this situation, in a further technical solution, the flexible ampoule cutting device of the embodiment of the present application can also include a base 500 and a lifting mechanism 600. The base 500 is connected to the electric clamp 100 through the lifting mechanism 600. The lifting mechanism 600 can drive the cutting blade 400 to move up and down relative to the ampoule 700. Even if the size of the ampoule 700 being cut changes, the cutting blade 400 can be moved to the cutting position at the bottleneck of the ampoule 700, thereby increasing the versatility of the flexible ampoule cutting device.

[0047] In the embodiment of the present application, the lifting mechanism 600 can be one of a screw-slide lifting mechanism, a gear rack lifting mechanism, and a chain lifting mechanism. In a preferred embodiment, the lifting mechanism 600 can be a screw-slide lifting mechanism. The screw-slide lifting mechanism has the characteristics of high precision, which enables the cutting blade 400 to accurately move to the cutting position of the ampoule 700.

[0048] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
