Detailed implementation manners

[0023] This application is made based on the inventor's discovery and recognition of the following facts and problems:

[0024] In the plasma bag conveying method in the related art, manual placement is adopted, which not only requires a large amount of labor costs, but also has low placement efficiency, affecting the overall production efficiency.

[0025] In some plasma bag conveying methods in the related art, a grasping device with suction cups is used to simultaneously adsorb multiple plasma bags for transfer and conveyance. However, due to the structural limitations of the grasping device and the limitations of the plasma bag placement method, only a small number of plasma bags can be grasped each time, resulting in low plasma bag transfer efficiency.

[0026] The spacing between plasma bags is different in different processes. Some grasping devices in the related art can adjust the spacing between plasma bags after adsorbing multiple plasma bags, but a large number of driving devices are required, the structure is complex, the control difficulty is high, and the grasping efficiency is low.

[0030] The plasma bag grasping device 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0031] As Figure 1 and Figure 2 shown, the plasma bag grasping device 1 according to an embodiment of the present utility model includes a bracket 10 and a plurality of grasping components 20.

[0032] Each grasping component 20 includes a limiting plate 21, a guide rail 22, a lifting driving device 23, a plurality of sliders 24, and a plurality of grasping devices 25. The limiting plate 21 is provided on the bracket 10, and a plurality of guide grooves 211 are provided on each limiting plate 21. The guide grooves 211 extend obliquely upward from the outside to the inside in the length direction of the guide rail 22. The guide rail 22 is vertically movably provided on the bracket 10 (the up-down, left-right, and front-back directions are as shown by the arrows in the figure and are only for convenience of description, not for the limitation of the actual setting direction). The lifting driving device 23 is in transmission connection with the guide rail 22. A plurality of sliders 24 are slidably provided on the guide rail 22 and are spaced apart in the length direction of the guide rail 22. At least a part of each slider 24 is slidably engaged in the guide groove 211. A plurality of grasping devices 25 are respectively connected to the plurality of sliders 24, and each grasping device 25 is adapted to grasp a plasma bag.

[0033] Specifically, the bracket 10 has an adapter post 11, and the bracket 10 can be installed on other mobile devices through the adapter post 11 to realize the overall movement of the plasma bag grasping device 1, such as a robotic arm, a truss, etc.

[0034] For example, when it is necessary to transfer the plasma bag, the bracket 10 first moves above the plasma bag to be grasped, so that the grasping device 25 contacts the plasma bag. The grasping device 25 grasps the plasma bag, and the lifting driving device 23 drives the guide rail 22 to rise. At the same time, the plurality of sliders 24 on the guide rail 22 move upward and approach each other under the cooperation with the guide groove 211, driving the plurality of grasping devices 25 and the plurality of plasma bags to move upward and approach each other. The bracket 10 moves to the release position, and the grasping device 25 releases the plasma bag, completing the transfer of the plurality of plasma bags.

[0035] According to the plasma bag grasping device 1 of the embodiment of the present utility model, by providing a plurality of grasping components 20, and each grasping component 20 includes a plurality of grasping devices 25, the grasping of a plurality of plasma bags can be achieved simultaneously. Compared with the method of manual transfer, the labor cost can be reduced, the automation degree of plasma bag transfer can be improved, and the transfer efficiency of plasma bags can be increased.

[0036] Moreover, by providing a limiting plate 21, a guide rail 22, a lifting driving device 23 and a plurality of sliders 24, at least a part of the sliders 24 is cooperated with the guiding grooves 211 on the limiting plate 21. When the lifting driving device 23 drives the guide rail 22 to lift or lower, the sliders 24 will approach or move away from each other accordingly, so as to adjust the distance between the grasping device 25 and the plasma bag. Thereby, the plasma bag grasping device 1 can adapt to different placement intervals of plasma bags in different processes, further facilitating the transfer of plasma bags between different processes by the plasma bag grasping device 1 and improving the applicability of the plasma bag grasping device 1.

[0037] In addition, by adopting the cooperation mode of the inclined guiding grooves 211 and at least a part of the sliders 24, not only can a lifting driving device 23 drive a plurality of grasping devices 25 to lift or lower, but also the distance between a plurality of grasping devices 25 can be adjusted during the lifting process. Compared with the related art in which a plurality of driving devices are provided, only one lifting driving device 23 needs to be provided for each grasping component 20. The number of driving devices can be reduced, the cost of additionally providing driving devices can be saved, the overall structure of the plasma bag grasping device 1 can be simplified, the control difficulty of the plasma bag grasping device 1 can be reduced, and the distance between the grasping devices 25 can be changed while lifting, so that the lifting and distance adjustment are carried out synchronously, and the transfer efficiency of plasma bags can be increased.

[0038] Therefore, the plasma bag grasping device 1 according to the embodiment of the present utility model has the advantages of saving manpower, high plasma bag transfer efficiency, strong applicability, low cost, etc.

[0039] Next, the plasma bag grasping device 1 according to the specific embodiment of the present utility model will be described with reference to the accompanying drawings.

[0040] In some specific embodiments of the present utility model, as Figure 1 and Figure 2 shown, the plasma bag grasping device 1 according to the embodiment of the present utility model includes a bracket 10 and a plurality of grasping components 20.

[0041] Specifically, as Figure 1 and Figure 2 shown, a plurality of grasping components 20 are arranged at intervals along a first horizontal direction on the bracket 10, the guide rail 22 is oriented along a second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction. Specifically, the first horizontal direction is Figure 1The left - right direction indicated by the arrow in the figure, and the second horizontal direction is Figure 2 the front - back direction indicated by the arrow in the figure. This facilitates the grasping of multiple plasma bags arranged in an array.

[0042] More specifically, as Figure 1 and Figure 2 shown, each grasping device 25 includes a grasping frame 251 and a plurality of suction cups 252. The grasping frame 251 is connected to the slider 24. The plurality of suction cups 252 are arranged in an array on the grasping frame 251. Specifically, the number of suction cups 252 is 6 or 8 and they are arranged in two rows along the left - right direction on the grasping frame 251. In this way, the plurality of suction cups 252 can be used to adsorb the plasma bags, realizing the grasping of the plasma bags, ensuring the stability of the grasped plasma bags, and preventing the plasma bags from falling off during the transfer process.

[0043] Advantageously, as Figure 1 and Figure 2 shown, the plasma - bag grasping device 1 further includes a plurality of suction - cup control devices 30. The suction - cup control devices 30 are arranged on the bracket 10 and are respectively connected to the plurality of suction cups 252 through air circuits. In this way, the suction - cup control devices 30 can be used to control the suction or deflation of the suction cups 252, realizing the adsorption or release of the plasma bags.

[0044] More advantageously, a check valve is provided inside each suction cup 252. This can prevent the plasma bags from detaching from the suction cups 252 or the failure of adsorbing the plasma bags due to air leakage, thus ensuring the reliability of the adsorption.

[0045] Optionally, a plasma - bag grasping - state monitoring device is provided on each grasping device 25. Specifically, the plasma - bag grasping - state monitoring device can be a photoelectric sensor, and the plasma - bag grasping - state monitoring device is also electrically connected to an alarm device to issue a prompt alarm when the grasping fails. Thus, the plasma - bag grasping - state monitoring device can be used to detect whether the corresponding grasping device 25 has grasped the plasma bag.

[0046] Figure 2 shows the plasma - bag grasping device 1 according to some examples of the present invention. As Figure 2As shown, the angle formed by the guiding groove 211 relatively closer to the inner side in the length direction of the guiding rail 22 and the horizontal direction is greater than the angle formed by the guiding groove 211 relatively closer to the outer side in the length direction of the guiding rail 22 and the horizontal direction. It should be understood here that "closer" is relative and not a limitation on the actual set distance. For example, there may be four guiding grooves 211 on each limiting plate 21. The angles formed by the two guiding grooves 211 relatively closer to the center of the guiding rail 22 and the horizontal direction are equal, the angles formed by the two guiding grooves 211 relatively closer to both ends of the guiding rail 22 and the horizontal direction are equal, and the angle formed by the guiding groove 211 relatively closer to the center of the guiding rail 22 and the horizontal direction is greater than the angles formed by the two guiding grooves 211 relatively closer to both ends of the guiding rail 22 and the horizontal direction. Thus, the greater the distance from the center of the guiding rail 22, the greater the horizontal displacement of the gripping device 25 during the lifting process, which facilitates the adjustment of the spacing of the gripping device 25 during the lifting process and helps to keep the spacing of the gripping device 25 uniform during the lifting process.

[0047] Optionally, the bracket 10 is adapted to be connected to a robotic arm. Specifically, the bracket 10 has an adapter post 11, and the bracket 10 is connected to the robotic arm through the adapter post 11. This facilitates the overall movement of the plasma bag gripping device 1 by using the robotic arm and improves the freedom of movement of the plasma bag gripping device 1.

[0048] Advantageously, each slider 24 has a guiding member, and a plurality of the guiding members are respectively fitted in a plurality of guiding grooves 211. In this way, the cooperation between the guiding member and the guiding groove 211 can enable the slider 24 to adjust the horizontal spacing while lifting.

[0049] Furthermore, the guiding member is a bearing. This facilitates the sliding of the guiding member in the guiding groove 211, reduces the resistance when the guiding member slides in the guiding groove 211, and makes the movement of the gripping device 25 smoother.

[0050] Specifically, as Figure 1 and Figure 2 shown, there are four gripping assemblies 20, and each gripping assembly 20 has four gripping devices 25. In this way, the gripping of 16 plasma bags can be achieved simultaneously, improving the transfer efficiency of the plasma bags.

[0051] Other configurations and operations of the plasma bag gripping device 1 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0052] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0053] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
