Description

Technical Field

[0001] The utility model belongs to the technical field of biological storage equipment, and in particular relates to a grabbing mechanism for ultra-low temperature biological storage equipment. Background Art

[0002] Ultra-low temperature biological storage equipment needs to store biological organisms including human organ tissues, whole blood, plasma, serum, biological fluids or processed biological samples under ultra-low temperature conditions, and has stringent requirements on the conditions of low-temperature insulated storage tanks. Therefore, it is required that a low-temperature insulated storage tank of an ultra-low temperature biological storage equipment store as many biological samples as possible in order to save storage costs. Therefore, the vacuum insulated storage tank will be equipped with more storage units, and each storage unit will be equipped with many layers of sub-storage units, so that each storage unit will have a higher height. When the grabbing mechanism intelligently grabs the storage unit and puts it into the low-temperature insulated storage tank or takes out the storage unit and transfers it to the material collection window, the storage unit is prone to shaking and instability, which is not conducive to the access and transfer of the storage unit.

[0014] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the present invention, but the description is for the purpose of illustrating the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined as defined by the attached claims.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings, but the accompanying drawings are not intended to limit the present invention.

[0016] Example

[0017] like Figure 1-6 As shown, a gripping mechanism for ultra-low temperature biological storage equipment includes a gripping mechanism body 1, which includes a mounting bracket 1a, a driving electromagnet 1b, a plurality of gripping claws 1c and a center positioning shaft 1d. The driving electromagnet 1b, the plurality of gripping claws 1c and the center positioning shaft 1d are all arranged on the mounting bracket 1a. The driving electromagnet 1b drives the center positioning shaft 1d to dock and position with the storage unit. At the same time, the driving electromagnet 1b also drives the plurality of gripping claws 1c to grip, thereby preventing the storage unit from shaking during access or transportation.

[0018] Preferably, the grabbing claw 1c includes a grabbing head 1c1 and a driving seat 1c3, the grabbing head 1c1 is pivotally set on the mounting bracket 1a, and the grabbing head 1c1 and the driving seat 1c3 are connected by a driving rod 1c2; the center positioning shaft 1d is set at the output end of the driving electromagnet 1b, and the driving seat 1c3 is slidably sleeved on the center positioning shaft 1d, and the center positioning shaft 1d is provided with a locking part 1b1 at one end close to the driving electromagnet 1b, and a driving spring 1e is provided between the locking part 1b1 and the driving seat 1c3.

[0019] During the storage unit grabbing process, the driving electromagnet 1b drives the central positioning shaft 1d to move and secure the storage unit. During this process, the driving spring 1e drives the driving seat 1c3 to move synchronously, which in turn causes the driving seat 1c3, via the driving rod 1c2, to drive the gripping head 1c1 outward to grab the storage unit. This method of using the driving spring 1e to drive the gripping head 1c1 outward to grab the storage unit not only ensures stable grabbing, but also acts as a buffer, preventing the gripping head 1c1 from impacting the grabbing opening 2a1 of the storage unit 2a during the grabbing process, thereby improving performance.

[0020] More preferably, the gripping head 1c1 is further provided with a movable clamping head 1c4 via a rotating shaft 1c5, and a plurality of compression springs 1c6 are interposed between the movable clamping head 1c4 and the gripping head 1c1. The clamping head 1c4 is movably disposed on the gripping head 1c1, and the compression springs 1c6 interposed between the clamping head 1c4 and the gripping head 1c1 effectively adjust the contact surface between the clamping head 1c4 and the wall of the gripping opening 2a, thereby enhancing the gripping adaptability of the gripping head 1c1.

[0021] More preferably, the grabbing claws 1c are provided in three groups, and the three groups of grabbing claws 1c are evenly distributed radially along the central positioning axis 1d.

[0022] More preferably, a limiting step 1d1 is further provided on the central positioning shaft 1d, and the driving seat 1c3 is limited by the limiting step 1d1 to prevent the grasping claw 1c from having an excessive stroke and the grasping head 1c1 from grasping too tightly when grasping the storage unit 2.

[0023] like Figure 6 As shown, the biological storage unit 2a has a gripping opening 2a1 at its top, with a positioning hole 2a2 at its center. The lower end of the storage unit 2a is equipped with several layers of sub-storage units 2a3, each of which houses a biological storage box 2a4. This gives the entire storage unit 2a a relatively high height. To retrieve a storage unit 2a, the entire gripping mechanism moves downward, inserting its multiple gripping heads 1c1 into the gripping opening 2a1. The driving electromagnet 1b also drives the central positioning shaft 1d into the positioning hole 2a2, docking and positioning the storage unit 2a. Simultaneously, the driving electromagnet 1b drives the gripping heads 1c1 of the gripping claw 1c to expand outward, grasping the gripping opening 2a1 and completing the capture of the storage unit 2a. Therefore, the storage unit 2a is positioned and fixed by the central positioning axis 1d in the grasping mechanism, and the storage unit 2a is grasped by a plurality of card grasping heads 1c1, thereby solving the problem of easy shaking of the storage unit 2a during access or transportation, and improving the stability of the grasping and transportation process of the storage unit 2a.

[0024] The utility model relates to a gripping mechanism for ultra-low temperature biological storage equipment, comprising a gripping mechanism body, the gripping mechanism body comprising a mounting bracket, a driving electromagnet, a plurality of gripping claws, and a center positioning shaft, the driving electromagnet, the plurality of gripping claws, and the center positioning shaft all being arranged on the mounting bracket, the driving electromagnet driving the center positioning shaft to dock and position the storage unit, and the driving electromagnet also driving the plurality of gripping claws to grip the storage unit, thereby preventing the storage unit from shaking during access or transport. The gripping mechanism positions and fixes the storage unit via the center positioning shaft, while simultaneously gripping the storage unit via a plurality of gripping heads, thereby resolving the problem of the storage unit easily shaking during access or transport, and improving the stability of the storage unit gripping and transporting process, with a simple structure and good practicality.
