详述Elaborate

下文中将结合附图对本公开的实施例进行详细说明。Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

实施例一：Embodiment one:

如图1和图2所示，本公开的实施例提供了一种药瓶夹持装置，包括基座1、夹持机构和驱动机构。其中，基座用于安装、支撑夹持机构和驱动机构；夹持机构用于形成夹持药瓶的夹持空间，驱动机构带动夹持机构运动，以夹紧药瓶，以及在夹紧药瓶后继续带动药瓶运动，促进药瓶内的药物溶解、混合等，提高配药效率。As shown in FIGS. 1 and 2, an embodiment of the present disclosure provides a medicine bottle holding device including a base 1, a holding mechanism, and a driving mechanism. The base is used for mounting and supporting the clamping mechanism and the driving mechanism; the clamping mechanism is used to form a clamping space for clamping the medicine bottle; the driving mechanism drives the clamping mechanism to move to clamp the medicine bottle and clamp the medicine After the bottle, the medicine bottle movement is continued to promote the dissolution and mixing of the medicine in the medicine bottle and improve the dispensing efficiency.

具体地，夹持机构包括承接座、多个夹块和夹紧部件。Specifically, the clamping mechanism includes a receiving seat, a plurality of clamping blocks, and a clamping member.

承接座可运动地安装在基座上。The receiving seat is movably mounted on the base.

多个夹块安装在承接座上，并在多个夹块之间形成夹持空间，该夹持空间用于放置药瓶，多个夹块中至少一个为可相对于承接座运动的运动夹块，运动夹块可相对于承接座运动，以使夹持空间能够在夹紧状态和释放状态之间变化，以便夹紧药瓶或松开药瓶。A plurality of clamping blocks are installed on the receiving seat, and a clamping space is formed between the plurality of clamping blocks. The clamping space is used for placing a medicine bottle, and at least one of the plurality of clamping blocks is a moving clamp movable relative to the receiving seat. Block, the moving clamp block can move relative to the receiving seat, so that the clamping space can be changed between the clamped state and the released state, so as to clamp or release the medicine bottle.

夹紧部件的一端与驱动机构连接，另一端与运动夹块传动连接，并且夹紧部件能够相对于承接座运动以带动运动夹块运动，或者夹紧部件能够相对于承接座固定以带动承接座运动。One end of the clamping member is connected to the driving mechanism, and the other end is drivingly connected to the moving clamp block, and the clamping member can move relative to the receiving seat to drive the movement clamping block, or the clamping member can be fixed relative to the receiving seat to drive the receiving seat. motion.

夹紧部件的一端与驱动机构连接，另一端与运动夹块传动连接，且夹紧部件既能够相对于承接座运动，还能够相对于承接座固定，这样，一方面，在夹紧药瓶的过程中，驱动机构带动夹紧部件相对于承接座运动，夹紧部件带动运动夹块运动，使夹持空间变化至夹紧状态，将药瓶夹紧；另一方面，在配药过程中，夹紧部件因已经夹紧药瓶而不能继续相对于承接座运动，继而变为相对于承接座固定，此时夹持空间保持处于夹紧状态，驱动机构继续带动夹紧部件运动，夹紧部件进而带动与其相对固定的承接座运动，进而带动药瓶运动，以促进药瓶内的药物溶解、混合等，提高配药效率。One end of the clamping member is connected to the driving mechanism, and the other end is drivingly connected to the movement clamping block, and the clamping member can move relative to the receiving seat and be fixed relative to the receiving seat. In this way, on the one hand, In the process, the driving mechanism drives the clamping component to move relative to the receiving seat. The clamping component drives the movement clamping block to change the clamping space to the clamping state and clamp the medicine bottle. On the other hand, during the dispensing process, the clamp The tight part cannot continue to move relative to the receiving seat because the medicine bottle has been clamped, and then becomes fixed relative to the receiving seat. At this time, the clamping space remains in a clamped state, and the driving mechanism continues to drive the clamping part to move, and the clamping part further The movement of the receiving seat which is relatively fixed is driven, and then the medicine bottle is moved to promote the dissolution and mixing of the medicine in the medicine bottle and improve the dispensing efficiency.

本实施例的药瓶夹持装置中，运动夹块夹紧药瓶以及带动药瓶运动均是由驱动机构和夹紧部件带动，通过不同的驱动机构分别实现夹紧药瓶和带动药瓶运动的技术方案相比，本公开实施例的药瓶夹持装置通过一套驱动机构和夹紧部件实现了夹紧药瓶和带动药瓶运动的双重功能，且药瓶夹持装置的结构简化，成本低，故障率低。In the medicine bottle clamping device of this embodiment, the movement of the medicine bottle to clamp the medicine bottle and the movement of the medicine bottle are driven by the driving mechanism and the clamping member, and the medicine bottle is clamped and the medicine bottle is moved by different driving mechanisms. Compared with the technical solution, the medicine bottle holding device of the embodiment of the present disclosure realizes the dual functions of clamping the medicine bottle and driving the movement of the medicine bottle through a set of driving mechanisms and clamping members, and the structure of the medicine bottle holding device is simplified. Low cost and low failure rate.

在此需要说明的是，本公开中的“连接”可以是指“接触”。It should be noted here that “connected” in the present disclosure may mean “contact”.

在图1和图2所示的具体示例中，承接座为承接盘15，并且可转动地安装在基座1上。承接盘15与基座1之间设有轴承23，轴承23的外圈与基座1固定，轴承23的内圈与承接盘15固定。In the specific example shown in FIGS. 1 and 2, the receiving seat is a receiving tray 15 and is rotatably mounted on the base 1. A bearing 23 is provided between the receiving disk 15 and the base 1. An outer ring of the bearing 23 is fixed to the base 1, and an inner ring of the bearing 23 is fixed to the receiving disk 15.

承接盘15上安装有4个夹块10、11、12、13，且4个夹块10、11、12、13均为运动夹块，4个运动夹块10、11、12、13分别通过4个转轴16、17、18、19可转动地安装在承接盘15上。Four clamping blocks 10, 11, 12, 13 are installed on the receiving tray 15, and the four clamping blocks 10, 11, 12, 13 are all moving clamping blocks, and the four moving clamping blocks 10, 11, 12, and 13 pass through respectively. The four

rotating shafts

16, 17, 18, and 19 are rotatably mounted on the receiving tray 15.

与4个运动夹块10、11、12、13相配合，设置了4个夹紧部件，4个夹紧部件与4个运动夹块10、11、12、13一一对应，用于带动对应的运动夹块转动。承接盘15上设置有与4个运动夹块10、11、12、13相对应的4个圆弧形的限位槽(图中仅示出了其中两个限位槽24和25)，每一个夹紧部件一端与驱动机构连接，另一端穿过相应的限位槽，并与对应的运动夹块传动连接，以带动对应的运动夹块转动。Cooperate with 4 moving clamps 10, 11, 12, 13 and set up 4 clamping parts. The 4 clamping parts correspond to the 4 moving clamps 10, 11, 12, 13 one by one for driving correspondence. The moving clamp block rotates. The receiving tray 15 is provided with four arc-shaped limiting grooves corresponding to the four moving clamp blocks 10, 11, 12, 13 (only two of the limiting

grooves

24 and 25 are shown in the figure). One end of a clamping component is connected with the driving mechanism, and the other end passes through the corresponding limiting slot, and is connected with the corresponding motion clamp block to drive the corresponding motion clamp block to rotate.

驱动机构为旋转驱动机构，旋转驱动机构能够带动夹紧部件在限位槽内滑动，并相对于承接盘15转动，夹紧部件带动运动夹块10、11、12、13绕转轴16、17、18、19转动，使夹持空间28变化至夹紧状态，夹紧药瓶；并且当夹紧药瓶后，运动夹块10、11、12、13无法继续转动，因而夹紧部件无法继续相对于承接盘15转动，使夹紧部件与承接盘15变为相对固定，此时旋转驱动机构可通过夹紧部件带动承接盘15转动，使药瓶转动，以促进药瓶内药物在溶配药过程中的溶解、混合。The driving mechanism is a rotary driving mechanism. The rotary driving mechanism can drive the clamping member to slide in the limit groove and rotate relative to the receiving disk 15. The clamping member drives the moving clamp blocks 10, 11, 12, 13 around the

rotation shafts

16, 17, and

Turning

18 and 19 changes the clamping space 28 to the clamping state and clamps the medicine bottle; and after clamping the medicine bottle, the movement clamp blocks 10, 11, 12, 13 cannot continue to rotate, so the clamping parts cannot continue to face each other When the receiving tray 15 rotates, the clamping member and the receiving tray 15 become relatively fixed. At this time, the rotation driving mechanism can drive the receiving tray 15 to rotate through the clamping member, so that the medicine bottle is rotated to promote the dissolution and dispensing process of the medicine in the medicine bottle. Dissolve and mix in.

每一个夹紧部件都包括1个动力轴(如图中的动力轴4、29和30)和1个挤压轮组(包括挤压轮)，动力轴的一端与驱动机构连接，挤压轮组安装在动力轴的另一端，且与运动夹块的外侧表面相抵压。夹紧部件的具体结构将在下面详细描述，在此不再赘述。Each clamping part includes a power shaft (such as

power shafts

4, 29, and 30 in the figure) and an extrusion wheel set (including extrusion wheels). One end of the power shaft is connected to the driving mechanism. The extrusion wheel The group is installed at the other end of the power shaft and presses against the outer surface of the moving clamp block. The specific structure of the clamping member will be described in detail below, and will not be repeated here.

应当理解，夹块的数量并不限于附图所示的数量，夹块中可以有一部分固定安装在承接盘上，一部分可运动地安装在承接盘上，以实现药瓶的夹紧和释放。可以根据实际需要，设定夹块的数量。It should be understood that the number of clamping blocks is not limited to the number shown in the drawings, and a part of the clamping blocks may be fixedly mounted on the receiving tray and a part may be movably mounted on the receiving tray to achieve clamping and release of the medicine bottle. The number of clamping blocks can be set according to actual needs.

在附图所示的示例中，通过运动夹块10、11、12、13夹持药瓶、运动夹块10、11、12、13无法继续转动，因而夹紧部件无法继续相对于承接盘15转动，实现了夹紧部件与承接盘15的相对固定。应当理解，还可以通过其他方式实现夹紧部件与承接盘15的相对固定。如：可在承接盘15上设置限位部，当夹紧部件相对于承接盘15运动到某一位置(如夹持空间28处于夹紧状态并夹紧药瓶)后，限位部能够与夹紧部件配合，阻挡夹紧部件相对于承接座继续运动，使夹紧部件与承接盘15相对固定，以便夹紧部件带动承接座运动，进而带动承接座上的药瓶运动，促进药物溶解、混合。设置限位部，可以避免运动夹块10、11、12、13施加给药瓶过大的夹持力。在附图所示的示例中，限位槽一端的槽壁可用作限位部，当夹紧部件转动到与限位槽一端的槽壁相抵接后，阻挡夹紧部件相对于承接座继续转动，使夹紧部件与承接座相对固定，此时夹紧部件带动承接座转动。In the example shown in the drawings, the medicine bottle is held by the moving

clamps

10, 11, 12, 13 and the moving

clamps

10, 11, 12, 13 cannot continue to rotate, so the clamping member cannot continue to be relative to the receiving disk 15 By rotating, the relative fixing of the clamping member and the receiving plate 15 is achieved. It should be understood that the relative fixing of the clamping member to the receiving plate 15 can also be achieved in other ways. For example, a stopper can be provided on the receiving tray 15. When the clamping member moves to a certain position relative to the receiving tray 15 (such as the clamping space 28 is in a clamped state and clamps the medicine bottle), the stopper can communicate with The clamping members cooperate to prevent the clamping member from continuing to move relative to the receiving seat, so that the clamping member is relatively fixed to the receiving tray 15 so that the clamping member drives the receiving seat to move, which in turn drives the medicine bottle on the receiving seat to promote drug dissolution, mixing. Setting the limiting part can prevent the

movement clamping block

10, 11, 12, 13 from applying excessive clamping force to the medicine bottle. In the example shown in the drawing, the groove wall at one end of the limiting groove can be used as a limiting portion. When the clamping member rotates to abut the groove wall at one end of the limiting groove, the clamping member is prevented from continuing with respect to the receiving seat. Rotating makes the clamping member relatively fixed to the receiving seat. At this time, the clamping member drives the receiving seat to rotate.

可选地，药瓶夹持装置还包括阻尼装置，阻尼装置设置在承接座与基座之间。Optionally, the medicine bottle holding device further includes a damping device, and the damping device is disposed between the receiving seat and the base.

承接座与基座之间的阻尼装置可阻碍承接座相对于基座的运动，这样在驱动机构带动夹紧部件运动的过程中，由于阻尼装置的阻尼力阻碍承接座运动，夹紧部件无法起始就带动承接座运动，而是先相对于承接座运动，并带动运动夹块运动，以夹紧药瓶；运动夹块与药瓶接触、夹紧药瓶后，运动夹块无法继续运动，进而使得夹紧部件无法继续相对于承接座运动，即此时夹紧部件与承接座变为相对固定，若驱动机构继续带动夹紧部件运动，则夹紧部件带动承接座运动，并克服承接座与基座之间的阻尼装置的阻尼力，承接座运动能够带动其上的药瓶运动，以促进药瓶内的药物溶解、混合等。The damping device between the receiving seat and the base can hinder the movement of the receiving seat relative to the base. In this process, when the driving mechanism drives the clamping member to move, the clamping member cannot move due to the damping force of the damping device blocking the movement of the receiving seat From the beginning, the socket is moved, but it is moved relative to the socket, and the movement clamp block is moved to clamp the medicine bottle. After the movement clamp block contacts the medicine bottle and clamps the medicine bottle, the movement clamp block cannot continue to move. As a result, the clamping member cannot continue to move relative to the receiving seat, that is, the clamping member and the receiving seat become relatively fixed at this time. If the driving mechanism continues to drive the clamping member to move, the clamping member drives the receiving seat to move and overcomes the receiving seat. With the damping force of the damping device between the base and the base, the movement of the receiving seat can drive the medicine bottle on it to promote the dissolution and mixing of the medicine in the medicine bottle.

运动夹块对药瓶的夹持力的大小与阻尼装置施加于承接盘的阻尼力有关，阻尼力越大，夹持力越大。The magnitude of the clamping force of the movement clamping block on the medicine bottle is related to the damping force applied by the damping device to the receiving plate. The larger the damping force, the greater the clamping force.

具体地，在附图所示的具体示例中，阻尼装置包括摩擦块14，摩擦块固定在基座1上，承接盘15与摩擦块14接触，可以如图中所示的侧面接触。摩擦块14可提供摩擦阻力，以阻碍承接盘15相对于基座1转动，使夹紧部件能够先带动运动夹块10、11、12、13转动，以夹紧药瓶。Specifically, in the specific example shown in the drawings, the damping device includes a friction block 14 which is fixed on the base 1 and the receiving plate 15 is in contact with the friction block 14 and may be in contact with the side as shown in the figure. The friction block 14 can provide frictional resistance to prevent the receiving tray 15 from rotating relative to the base 1, so that the clamping component can first drive the moving clamping

block

10, 11, 12, 13 to rotate to clamp the medicine bottle.

在另一种具体示例中，阻尼装置可以包括阻尼轴承，阻尼轴承包括轴承外圈和轴承内圈，轴承外圈固定在基座和承接座中的一个上，轴承内圈固定在基座和承接座中的另一个上。如：可以用阻尼轴承代替普通的轴承23，利用阻尼轴承的阻尼对承接盘15转动施加阻力。In another specific example, the damping device may include a damping bearing. The damping bearing includes a bearing outer ring and a bearing inner ring. The bearing outer ring is fixed on one of the base and the bearing seat. The bearing inner ring is fixed on the base and the bearing. On the other seat. For example, a damping bearing may be used instead of the ordinary bearing 23, and the damping of the damping bearing may be used to apply resistance to the rotation of the receiving plate 15.

在又一种具体示例中，阻尼装置包括阻尼器，阻尼器包括可伸缩的阻尼杆，阻尼器安装在基座和承接座中的一个上，阻尼杆连接至基座和承接座中的另一个上。阻尼杆伸缩时会对承接座施加阻尼力，以阻碍承接座相对于基座运转动。In yet another specific example, the damping device includes a damper, the damper includes a retractable damping rod, the damper is mounted on one of the base and the socket, and the damping rod is connected to the other of the base and the socket on. When the damping rod is retracted, a damping force is applied to the receiving seat to prevent the receiving seat from moving relative to the base.

应当理解，阻尼装置并不限于上述三种结构，还可以为其他形式，在此不再赘述。It should be understood that the damping device is not limited to the three structures described above, and may also be in other forms, which is not repeated here.

可选地，夹紧部件与运动夹块之间为单向传动连接，即夹紧部件朝向一个方向运动时可带动运动夹块运动，以使夹持空间变化至夹紧状态(或释放状态)，当夹紧部件朝向相反方向运动时，夹紧部件不带动运动夹块运动，无法使夹持空间由夹紧状态变化至释放状态(或由释放状态变化至夹紧状态)，因此，夹持机构还包括复位弹性件，复位弹性件设置在承接座与运动夹块之间，运动夹块在复位弹性件的作用下运动，使夹持空间能够由夹紧状态变化至释放状态(或由释放状态变化至夹紧状态)。这样通过夹紧部件和复位弹性件配合，使运动夹块能够往复运动，进而使夹持空间能够在夹紧状态和释放状态之间变化，达到夹紧药瓶或松开药瓶的目的。Optionally, the clamping member and the moving clamp block are connected in a one-way transmission, that is, when the clamping member moves in one direction, the moving clamp block can be driven to move the clamping space to a clamping state (or a releasing state). When the clamping member moves in the opposite direction, the clamping member does not drive the moving clamping block to change the clamping space from the clamping state to the releasing state (or from the releasing state to the clamping state). Therefore, the clamping The mechanism also includes a reset elastic member, which is disposed between the receiving seat and the movement clamping block, and the movement clamping block moves under the action of the reset elastic member, so that the clamping space can be changed from the clamped state to the released state (or released by State changes to the clamped state). In this way, by cooperating with the clamping member and the reset elastic member, the moving clamping block can reciprocate, so that the clamping space can be changed between the clamped state and the released state, thereby achieving the purpose of clamping the medicine bottle or releasing the medicine bottle.

在附图所示的实施例中，夹紧部件与运动夹块10、11、12、13之间的单向传动连接，使夹持空间28仅能够由释放状态变化至夹紧状态。复位弹性件为弹簧，4个弹簧(图中仅示出了其中的2个弹簧8和9)分别套在转轴16、17、18、19上，且弹簧的一个端部与运动夹块抵接固定。承接盘15上设有4个固定柱(图中仅示出了其中的2个固定柱26和27)，固定柱上设有安装孔，弹簧的另一端伸入该安装孔内。在弹簧的作用下，使夹持空间28默认处于释放状态。其中，所述弹簧可以是扭簧。In the embodiment shown in the drawings, the one-way transmission connection between the clamping member and the moving clamping blocks 10, 11, 12, 13 enables the clamping space 28 to be changed from the released state to the clamped state only. The resetting elastic member is a spring, and 4 springs (only 2 of which are shown in the figure 8 and 9) are sleeved on the

rotating shafts

16, 17, 18, and 19, respectively, and one end of the spring is in contact with the movement clamping block fixed. The receiving tray 15 is provided with 4 fixing posts (only two of the fixing posts 26 and 27 are shown in the figure). The fixing posts are provided with mounting holes, and the other end of the spring projects into the mounting holes. Under the action of the spring, the clamping space 28 is in a released state by default. The spring may be a torsion spring.

可选地，运动夹块的内侧表面为夹持表面，运动夹块的外侧表面与夹紧部件传动连接，且沿夹持空间变化至夹紧状态的过程中夹紧部件的运动方向，运动夹块的内侧表面和外侧表面彼此逐渐远离，也即夹块逐渐加厚。也可以这样理解，运动夹块的内侧表面为夹持表面，运动夹块的外侧表面与夹紧部件，例如与动力轴及挤压轮以滚动贴压方式连接，由释放至夹紧状态的运动过程中，夹紧部件保持围绕承接盘圆心以不变的半径转动，这时运动夹块的外侧表面因倾斜凸起并被夹紧部件的挤压轮滚动挤压而迫使运动夹块绕着转轴16，17，18，19向承接盘的圆心方向转动。当所有夹块内侧表面碰上药瓶时，药瓶即被夹紧。Optionally, the inner surface of the moving clamp block is a clamping surface, and the outer surface of the moving clamp block is drivingly connected to the clamping member, and along the moving direction of the clamping member during the change from the clamping space to the clamping state, the moving clamp The inner surface and the outer surface of the block are gradually separated from each other, that is, the clamping block is gradually thickened. It can also be understood that the inner surface of the movement clamp block is a clamping surface, and the outer surface of the movement clamp block is connected to the clamping member, such as the power shaft and the pressing wheel in a rolling and pressing manner, and the movement from the released to the clamped state During the process, the clamping member keeps rotating around the center of the receiving disk with a constant radius. At this time, the outer surface of the moving clamp block is inclined and protruded by the pressing wheel of the clamping member to force the moving clamp block around the rotation axis. 16, 17, 18, 19 Turn in the direction of the center of the receiving plate. When the inside surface of all the clamps touches the medicine bottle, the medicine bottle is clamped.

在附图所示的示例中，运动夹块10、11、12、13呈楔形，其内侧表面22为用于夹持药瓶的夹持表面，外侧表面21与夹紧部件传动连接，这样夹紧部件通过对外侧表面21施加力使运动夹块10、11、12、13转动，以便通过内侧表面22夹紧药瓶。此外，沿夹持空间28变化至夹紧状态的过程中夹紧部件的运动方向(如图中箭头所示的方向)，运动夹块10、11、12、13的内侧表面22和外侧表面21彼此逐渐远离，使得内侧表面22和外侧表面21之间的距离从一端(转轴16、17、18、19所在的一端)到另一端(远离转轴16、17、18、19的一端)逐渐增大，以便运动夹块10、11、12、13夹紧药瓶。在两端处外侧表面21与内侧表面22之间的距离的差值决定了可夹持药瓶的外径的范围，差值越大，可夹持药瓶的外径范围越大，差值越小，可夹持药瓶的外径范围越小。通过设置运动夹块10、11、12、13的内侧表面22和外侧表面21之间的距离变化，使得夹持空间28可用于夹持不同尺寸规格的药瓶，扩大了药瓶夹持装置的使用范围。In the example shown in the drawings, the movement clamping blocks 10, 11, 12, 13 are wedge-shaped, and the inner surface 22 is a clamping surface for holding a medicine bottle, and the outer surface 21 is drivingly connected to the clamping member, so that the clamp The tightening member rotates the moving

clamps

10, 11, 12, 13 by applying a force to the outer surface 21 so as to clamp the medicine bottle through the inner surface 22. In addition, along the movement direction of the clamping member during the change from the clamping space 28 to the clamping state (the direction shown by the arrow in the figure), the inner surface 22 and the outer surface 21 of the moving

clamps

10, 11, 12, and 13 Gradually move away from each other, so that the distance between the inner surface 22 and the outer surface 21 gradually increases from one end (the end where the

rotating shafts

16, 17, 18, 19 are located) to the other end (the end away from the rotating

shafts

16, 17, 18, 19). So that the movement clamp blocks 10, 11, 12, 13 clamp the medicine bottle. The difference between the distance between the outer surface 21 and the inner surface 22 at both ends determines the range of the outer diameter of the medicine bottle that can be clamped. The larger the difference, the larger the outer diameter range of the medicine bottle that can be clamped. The smaller the smaller the outer diameter range of the bottle that can be held. By setting the distance between the inner surface 22 and the outer surface 21 of the moving clamp blocks 10, 11, 12, and 13 to change, the clamping space 28 can be used to clamp medicine bottles of different sizes and specifications, and the size of the medicine bottle clamping device is enlarged. Use range.

可选地，在附图所示的示例中，包括4个夹紧部件，每一个夹紧部件包括1个动力轴和1个挤压轮组，动力轴的一端与驱动机构连接，挤压轮组安装在动力轴的另一端，且与运动夹块的外侧表面相抵压。每个挤压轮组包括2个挤压轮(图中只示出了3个动力轴4、29和30，另外一个因遮挡未示出，及安装在3个动力轴4、29和30上的3个挤压轮组的挤压轮5、6和7)。应当理解，每个挤压轮组包括的挤压轮的数量并不限于2个，可以根据需要，设计为包括1个，或3个以上的挤压轮。Optionally, in the example shown in the drawings, including four clamping members, each clamping member includes a power shaft and an extrusion wheel set, one end of the power shaft is connected to the driving mechanism, and the extrusion wheel The group is installed at the other end of the power shaft and presses against the outer surface of the moving clamp block. Each squeeze wheel set includes 2 squeeze wheels (only three

In the clamped state, clamp the vial.

具体地，电机2可具有上电自锁功能，当电机2停机时，电机2的驱动电路继续输出一个恒定电流使电机2抱轴而使电机输出轴刹车锁定，进而使夹紧部件保持在固定位置；或者，电机2可具有断电自锁功能，在电机2尾部加装一个抱闸装置(刹车装置)，并且在电机2上电时，抱闸装置也上电，抱闸装置脱离电机的输出轴，电机2正常运转，当断电时，刹车释放紧紧抱住电机输出轴，将电机输出轴锁定；或者，电机2的输出轴端设置有齿轮箱之类的可锁止的动力机构，当电机2断电后，利用齿轮箱内的齿轮之间的摩擦力使电机2的输出轴锁定。Specifically, the motor 2 may have a power-on self-locking function. When the motor 2 is stopped, the driving circuit of the motor 2 continues to output a constant current so that the motor 2 holds the shaft and locks the output shaft of the motor, thereby keeping the clamping component fixed. Position; or, the motor 2 may have a power-off self-locking function. A brake device (brake device) is installed at the end of the motor 2, and when the motor 2 is powered on, the brake device is also powered on, and the brake device is separated from the motor.

旋转驱动机构还可包括动力盘3，电机2通过电机轴20带动动力盘3转动，4个夹紧部件的动力轴均与动力盘3固定连接，这样可通过一个电机2同时带动4个运动夹块10、11、12、13转动，一方面减少了电机的数量，另一方面使4个运动夹块10、11、12、13同步转动，有利于保持药瓶夹紧后其中心位置保持不变。The rotary driving mechanism may further include a power disc 3, and the motor 2 drives the power disc 3 to rotate through the motor shaft 20. The power shafts of the four clamping components are fixedly connected to the power disc 3, so that one motor 2 can simultaneously drive four motion clamps.

Blocks

10, 11, 12, and 13 rotate, on the one hand, reducing the number of motors, and on the other hand, the four movement clamp blocks 10, 11, 12, 13, and 13 are rotated synchronously, which is beneficial to keeping the center position of the medicine bottle clamped. change.

可选地，4个动力轴与动力盘3连接的部位可以处于同一个圆上，4个运动夹块10、11、12、13的转轴16、17、18、19处于同一个圆上，该两个圆的圆心均位于动力盘3的转动轴线上，且4个运动夹块10、11、12、13的结构可以相同(包括形状和尺寸相同)，使得4个运动夹块10、11、12、13形成的夹持空间28的中心位置也位于动力盘3的转动轴线上，这样，药瓶被夹紧固定在夹持空间28内后，药瓶的中心位置固定，使药瓶装夹到准确位置，极大地提高了后续自动化配制药品时药液的抽吸等操作效率。Optionally, the positions where the four power shafts and the power disc 3 are connected may be on the same circle, and the

clamps

clamps

可选地，药瓶夹持装置包括多个驱动机构和多个夹持机构，多个驱动机构和多个夹持机构一一对应，每一驱动机构驱动对应的一个夹持机构运动，且多个夹持机构在基座1上线性排列或呈圆周阵列排布。多个夹持机构可夹持多个药瓶，便于溶配药时一次性对多个药瓶进行溶配药操作，提高溶配药效率。Optionally, the medicine bottle clamping device includes a plurality of driving mechanisms and a plurality of clamping mechanisms. The plurality of driving mechanisms correspond to the plurality of clamping mechanisms one by one. Each driving mechanism drives a corresponding one of the clamping mechanisms to move. The clamping mechanisms are linearly arranged on the base 1 or arranged in a circular array. Multiple clamping mechanisms can hold multiple medicine bottles, which is convenient for dissolving and dispensing multiple medicine bottles at one time when dissolving and dissolving medicines, and improving the efficiency of dissolving and dispensing medicines.

下面具体说明本实施所述的药瓶夹持装置的使用过程。The use process of the vial holding device according to this embodiment will be specifically described below.

当夹持空间28足以容纳药瓶时，将药瓶置于承接盘15上，或者将承接盘15置于药瓶上，并将药瓶放置在夹持空间28内，通电使电机2旋转，电机2带动动力盘3旋转，动力盘3带动固定其上的4个动力轴转动，电机2旋转初期，由于运动夹块10、11、12、13上有弹簧的弹性力，承接盘15被摩擦块14施加了阻尼力，且摩擦块14对承接盘15施加的转动阻力大于4个弹簧的总弹力，且小于电机2的驱动力，使承接盘15不能被立刻带动旋转，因此，4个动力轴在承接盘15上的限位槽内运动，使固定在动力轴上的挤压5、6和7轮挤压推动运动夹块10、11、12、13向夹持空间28内部转动，直至运动夹块10、11、12、13触碰到药瓶的外壁，这时运动夹块10、11、12、13不能继续向内转动。当动力轴的转动推动力大于摩擦块14施加于承接盘15上的阻力时，承接盘15开始转动，这样在药瓶被夹持的同时，药瓶夹持装置还能带动药瓶旋转。When the clamping space 28 is sufficient to accommodate the medicine bottle, place the medicine bottle on the receiving tray 15 or place the receiving plate 15 on the medicine bottle and place the medicine bottle in the clamping space 28. The electric motor 2 is rotated by being energized, The motor 2 drives the power disc 3 to rotate, and the power disc 3 drives the 4 power shafts fixed thereon to rotate. At the beginning of the rotation of the motor 2, due to the elastic force of the spring on the movement clamp blocks 10, 11, 12, 13, the receiving disc 15 is rubbed. The block 14 exerts a damping force, and the rotational resistance exerted by the friction block 14 on the receiving plate 15 is greater than the total elastic force of the four springs and is less than the driving force of the motor 2 so that the receiving plate 15 cannot be immediately driven to rotate. Therefore, 4 powers The shaft moves in the limiting groove on the receiving disk 15 so that the pressing 5, 6, and 7 wheels fixed on the power shaft push the moving clamp blocks 10, 11, 12, and 13 to rotate inside the clamping space 28 until The movement clamps 10, 11, 12, 13 touch the outer wall of the medicine bottle. At this time, the movement clamps 10, 11, 12, 13 cannot continue to rotate inward. When the driving force of the rotation of the power shaft is greater than the resistance exerted by the friction block 14 on the receiving plate 15, the receiving plate 15 starts to rotate, so that while the medicine bottle is being clamped, the medicine bottle clamping device can also drive the medicine bottle to rotate.

当电机2断电时，承接盘15停止转动，电机2的锁止功能使运动夹块10、11、12、13继续保持原有夹持位置及状态。When the motor 2 is powered off, the receiving tray 15 stops rotating, and the locking function of the motor 2 keeps the moving clamp blocks 10, 11, 12, and 13 to maintain the original clamping position and state.

当电机2反向旋转时，带动动力盘3反向旋转，动力盘3带动动力轴反向沿承接盘15上的限位槽运动，释放运动块10、11、12、13，运动夹块10、11、12、13在弹簧的弹力作用下向外运动，从而释放被夹持的药瓶。When the motor 2 rotates in the reverse direction, it drives the power plate 3 to rotate in the reverse direction. The power plate 3 drives the power shaft to move backward along the limit groove on the receiving plate 15, and releases the movement blocks 10, 11, 12, 13, and the movement clamping block 10. 11, 11, 12 and 13 move outward under the elastic force of the spring, thereby releasing the clamped medicine bottle.

实施例二：Embodiment two:

本实施例提供了一种药瓶夹持装置，其与实施例一所述的药瓶夹持装置的主要不同之处在于，夹紧部件与运动夹块之间为双向传动连接。This embodiment provides a medicine bottle holding device. The main difference between the medicine bottle holding device and the medicine bottle holding device described in the first embodiment is that the clamping component and the moving clamping block are connected in a bidirectional transmission.

夹紧部件与运动夹块之间为双向传动连接，即夹紧部件朝向一个方向及反向运动时均可带动运动夹块运动，以使夹持空间在夹紧状态和释放状态之间变化，达到夹紧药瓶或松开药瓶的目的。The clamping component and the moving clamp block are connected in a bidirectional transmission, that is, the clamping block can be driven to move in one direction and in the reverse direction, so that the clamping space changes between the clamped state and the released state. To achieve the purpose of clamping the bottle or loosening the bottle.

具体地，为实现夹紧部件与运动夹块之间的双向传动连接，可在运动夹块上开设滑槽，夹紧部件穿过滑槽或伸入滑槽内，这样当夹紧部件往复运动时均可带动运动夹块运动，以使夹持空间在夹紧状态和释放状态之间变化，达到夹紧药瓶或松开药瓶的目的。在该双向传动连接的结构中，可选择不使用弹性件。Specifically, in order to realize a bidirectional transmission connection between the clamping member and the moving clamping block, a sliding groove may be provided on the moving clamping block, and the clamping member passes through the sliding groove or extends into the sliding groove, so that when the clamping member reciprocates At any time, the movement clamping block can be driven to make the clamping space change between the clamping state and the releasing state, so as to achieve the purpose of clamping the medicine bottle or releasing the medicine bottle. In the structure of the bidirectional transmission connection, it is optional not to use an elastic member.

实施例三：Example three:

本实施例提供了一种药瓶夹持装置，其与实施例一所述的药瓶夹持装置的主要不同之处在于，运动夹块可移动地安装在承接座上。This embodiment provides a medicine bottle holding device, which is mainly different from the medicine bottle holding device described in the first embodiment in that a moving clamp block is movably mounted on the receiving seat.

为了实现运动夹块可移动地安装在承接座上，可在承接座和运动夹块之间设置直线型的滑轨和滑块，将滑轨固定在承接座上，将滑块固定在运动夹块上，以实现运动夹块与承接座的移动配合。In order to realize that the moving clamp block is movably installed on the receiving seat, a linear slide rail and a slider can be provided between the receiving seat and the moving clamp block. The slide rail is fixed on the receiving seat, and the slider is fixed on the moving clamp. On the block to achieve the movement cooperation of the moving clamp block and the receiving seat.

为了使带动药瓶运动过程中，药瓶的中心保持不动，故驱动机构和夹紧部件仍需进行旋转运动。这样，当驱动机构带动夹紧部件转动时，夹紧部件挤压运动夹块，使运动夹块沿滑轨移动，使夹持空间变化至夹紧状态，将药瓶夹紧；夹紧药瓶后，夹紧部件无法相对于承接座运动，并继续带动运动夹块转动，因此，夹紧部件相对于承接座固定，夹紧部件进而带动承接座转动，进而带动药瓶运动，以促进药瓶内的药物溶解、混合等，提高配药效率。In order to keep the center of the medicine bottle stationary during the process of driving the medicine bottle, the driving mechanism and the clamping member still need to perform a rotary movement. In this way, when the driving mechanism drives the clamping member to rotate, the clamping member squeezes the moving clamping block, moves the moving clamping block along the slide rail, changes the clamping space to the clamping state, and clamps the medicine bottle; clamping the medicine bottle Later, the clamping member cannot move relative to the receiving seat, and continues to drive the movement clamping block to rotate. Therefore, the clamping member is fixed relative to the receiving seat, and the clamping member further drives the receiving seat to rotate, thereby driving the medicine bottle to promote the medicine bottle Dissolve, mix, etc. the medicine inside, improve the dispensing efficiency.

需要说明的是，当药瓶夹持装置包括多个夹持机构和多个驱动机构时，多个夹持机构的结构可以相同，也可以不同，多个驱动机构的结构可以相同，也可以不同。如驱动机构和夹持机构可以采用上述三个实施例中任一个实施例中所述的夹持机构和驱动机构，或者可以采用不同实施例所述的夹持机构和驱动机构。It should be noted that when the medicine bottle clamping device includes multiple clamping mechanisms and multiple driving mechanisms, the structures of the multiple clamping mechanisms may be the same or different, and the structures of the multiple driving mechanisms may be the same or different. . For example, the driving mechanism and the clamping mechanism may adopt the clamping mechanism and the driving mechanism described in any one of the three embodiments described above, or may use the clamping mechanism and the driving mechanism described in different embodiments.

在本申请中，术语“传动连接”指两个部件之间能够传递运动的连接方式，但两个部件之间不一定存在连接关系，如两个部件之间可以仅通过相抵压、推挤来传递运动，或者，两个部件之间可以存在连接关系，从而进行同步运动。In the present application, the term "drive connection" refers to a connection mode capable of transmitting motion between two components, but there is not necessarily a connection relationship between the two components. For example, the two components can only be pressed or pushed against each other. Transfer motion, or there may be a connection relationship between the two parts to perform synchronized motion.
