Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a bottle breaking mechanism for an ampoule bottle. Background Art

[0002] An ampoule is a small glass container used to hold liquid medicine, often for injections. To access the liquid inside an ampoule, pressure is applied to the neck of the ampoule to break it.

[0003] At present, the common method for medical staff to break ampoules is to first grind the neck of the ampoule with a grinding wheel and then break it by hand. This method is inconvenient and will cause the neck of the bottle to break unevenly, which can easily injure the operator during the manual breaking process.

[0004] To address the aforementioned safety issues, existing technologies have devised mechanical devices for opening ampoules to replace manual operation, such as the automatic ampoule opening device disclosed in CN219526206U. This prior art utilizes a cylinder-driven hammer to horizontally strike the bottle head to break it. However, the horizontal lateral displacement of the bottle head relative to the bottle body can easily result in an uneven neck cut and generate a large number of glass fragments.

[0005] Therefore, there is still a need to improve the existing automatic opening device and method of ampoule bottles. Summary of the Invention

[0006] 1. Technical problem to be solved by the invention The purpose of the present invention is to solve the technical problems existing in the prior art and provide a bottle breaking mechanism, which can simulate the operation of manually breaking an ampoule bottle, and can better ensure that the bottle head is broken along the cut mark and the broken part is smoother.

[0007] 2. Technical solution In order to solve the above problems, the technical solution provided by the present invention is: A bottle breaking mechanism includes a driving mechanism and a turntable, wherein the driving mechanism is used to drive the turntable to rotate with point a as the center. A positioning rod and at least one breaking rod are vertically arranged on the same side of the turntable, the positioning rod is set at point a, and the breaking rod deviates from point a.

[0008] Preferably, the turntable is provided with two or more breaking rods, and the length of the breaking rods increases as the distance from the positioning rod increases.

[0009] Preferably, at least part of the outer ends of the breaking rods are provided with enlarged sleeves.

[0010] Preferably, 4. A bottle breaking mechanism according to claim 3, characterized in that: the enlarged sleeve is detachably connected to the breaking rod.

[0011] Preferably, the driving mechanism includes a servo motor and a reduction mechanism, and the servo motor is connected to the turntable through the reduction mechanism.

[0012] Preferably, the output end of the driving mechanism is connected to a connecting seat, and the turntable is detachably connected to the connecting seat.

[0013] Preferably, the turntable and the connecting seat are connected after matching through a positioning structure.

[0014] Preferably, it also includes an angle sensing mechanism for sensing the rotation angle of the turntable.

[0015] Preferably, a protective cover is provided on the turntable.

[0016] Preferably, a recycling box is provided below the turntable.

[0017] 3. Beneficial effects Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: As the turntable rotates, the breaking rod of this bottle-breaking mechanism applies an oblique force to the upper end of the ampoule tip, breaking it. This simulates the manual breaking of an ampoule. Compared to manual operation, the force applied by the breaking rod remains consistent during the breaking process, better ensuring that the tip of the ampoule breaks along the cut and the break is smoother. Furthermore, multiple ampoules can be broken simultaneously, greatly improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0020] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected" to another element, the two may be fixed in a detachable manner or in a non-detachable manner, such as socketing, snap-fitting, integrally molded fixing, welding, etc., which can be achieved in the prior art and will not be described in detail here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0023] Example 1 Combined with attachment Figure 1-4 , a bottle breaking mechanism of this embodiment includes a driving mechanism 10 and a turntable 20, the turntable 20 is arranged with a vertical plane as a reference plane, the driving mechanism 10 is used to drive the turntable 20 to rotate with point a as the center, in this embodiment, in order to maintain the stability of the turntable 20 during rotation, the turntable 20 is disc-shaped and the center of the circle coincides with point a; a positioning rod 30 and at least one breaking rod 40 are vertically arranged on the same side of the turntable 20, the positioning rod 30 and the breaking rod 40 are both arranged in the horizontal direction and the positioning rod 30 and the breaking rod 40 are arranged in parallel, the positioning rod 30 is set at point a, and the breaking rod 40 deviates from point a. When the turntable 20 rotates, since the positioning rod 30 is located at the rotation center of the turntable 20, no displacement will occur, and the breaking rod 40 will make a circular motion with point a as the center.

[0024] The working principle of the bottle breaking mechanism is as follows: after the ampoule is cut by the bottle cutting mechanism, the ampoule is moved to the bottle breaking mechanism by the robot. The neck of the ampoule is located between the positioning rod 30 and the breaking rod 40. The robot clamps the middle and lower part of the ampoule, and the positioning rod 30 is against one side of the bottle mouth of the ampoule (the positioning rod 30 and the breaking rod 40 are respectively located on both sides of the ampoule). Figure 2 As shown, when the turntable 20 rotates, the breaking rod 40 applies an oblique force to the upper end of the bottle head of the ampoule bottle to break it off. This method simulates the operation of manually breaking the ampoule bottle. Compared with manual operation, the force applied by the breaking rod 40 during the breaking process is always consistent, which can better ensure that the bottle head is broken along the cut mark, and the break is smoother. If the positioning rod 30 is not provided, the force on the ampoule bottle body is more serious when breaking, and the bottle body is very easy to break when the bottle head is broken off. When the robot clamps multiple ampoules, multiple ampoules can be broken at the same time, which greatly improves efficiency.

[0025] As a preferred embodiment of the present invention, Figure 1 As shown, the driving mechanism 10 includes a servo motor 101 and a reduction mechanism 102. The servo motor 101 is connected to the turntable 20 through the reduction mechanism 102. In this embodiment, the reduction mechanism 102 is composed of two bevel gears. Its main function is to reduce the rotation speed of the turntable 20 and increase the torque so that the ampoule bottle can be broken under low speed and high torque conditions.

[0026] As a preferred embodiment of the present invention, Figure 4 As shown, the output end of the driving mechanism 10 is connected to the connecting seat 60, and the turntable 20 is detachably connected to the connecting seat 60. The connecting seat 60 can be quickly disassembled from the turntable 20 to facilitate the cleaning of the bottle-breaking part. At the same time, in order to facilitate the precise docking of the connecting seat 60 and the turntable 20 and ensure that the position of point a remains unchanged, the turntable 20 and the connecting seat 60 are connected after matching through the positioning structure 70. In this embodiment, the positioning structure 70 includes a protrusion provided on the turntable 20 and a positioning groove provided on the connecting seat 60. Of course, the positions of the protrusion and the positioning groove can be interchanged. After the positioning structure 70 is matched, the turntable 20 and the connecting seat 60 are locked by bolts or the like.

[0027] As a preferred embodiment of the present invention, Figure 1As shown, it also includes an angle sensing mechanism 80 for sensing the rotation angle of the turntable 20, ensuring that the ampoule can be accurately broken every time the turntable 20 rotates. The interference between the breaking mechanism and the manipulator can be avoided by linkage with the manipulator. Specifically, there are many ways to implement the angle sensing mechanism 80. In this embodiment, a slot switch and a sensor sheet are selected for implementation. For example, the sensor sheet is fixed on the turntable 20, and the slot switch is set on a fixed structure such as a frame. When the sensor sheet rotates with the turntable 20, it can be sensed every time it passes the slot switch. Of course, the sensor sheet can be fixed on a structure that is coaxial with the turntable 20 and rotates synchronously, such as a transmission shaft.

[0028] As a preferred embodiment of the present invention, Figure 3 As shown, a protective cover 90 is provided on the turntable 20 to prevent debris from splashing. The protective cover 90 covers the breaking rod 40 and has an opening on one side for allowing the ampoule bottle to enter.

[0029] As a preferred embodiment of the present invention, Figure 3 As shown, a recovery box 100 is provided below the turntable 20 , and the recovery box 100 below collects the broken parts and debris of the ampoule bottle.

[0030] Example 2 Combined with attachment Figure 5 In this embodiment, the difference from the embodiment 1 is that two or more breaking rods 40 are provided on the turntable 2, and the multiple breaking rods 40 are arranged along the same radial direction. The length of the breaking rod 40 increases as the distance from the positioning rod 30 increases. Figure 5 As shown, this embodiment includes a first bend lever 401 that is longer and farther from point a, and a second bend lever 402 that is shorter and closer to point a. The first bend lever 401 and the second bend lever 402 are designed to accommodate ampoules of different specifications (including long and short designs). When encountering an ampoule with a shorter neck, the second bend lever 402 can be used, but the ampoule needs to be placed closer to the turntable to contact the second bend lever 402. When encountering an ampoule with a longer neck and a larger size, the first bend lever 401 is used to bend it, but it needs to be placed relatively far away from the turntable 20. It should be noted that when there are multiple bend levers 40 of different lengths, it is necessary to first determine the length of the ampoule. This length value can be measured and obtained by a measuring mechanism or manually input, so as to ultimately determine which bend lever 40 to use for operation. For different ampoules, the relative distance between the manipulator and the turntable 20 needs to be controlled. Through the above structural design, the same mechanism can simultaneously adapt to the opening operation of ampoules of different specifications, and the opening effect of ampoules of different specifications can be guaranteed. The structure of this embodiment can not only break multiple ampoules at the same time, but also break multiple ampoules of different specifications at the same time.

[0031] As a preferred embodiment of the present invention, an enlarged sleeve 50 is provided on the outer end of at least some of the break rods 40. When the enlarged sleeve 50 is installed on the break rod 40, its center coincides with the center of the break rod 40. The enlarged sleeve 50 is made of the same material as the break rod 40, and preferably, a detachable connection is achieved through a threaded connection or the like. Generally speaking, only the longest break rod 40 is considered for installation of the enlarged sleeve 50, because the bottle head of a large-sized ampoule is also relatively large. The provision of the enlarged sleeve 50 can increase the contact area between the break rod 40 and the bottle head, making the force on the bottle head more uniform and improving the breaking effect.

[0032] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
