TECHNICAL FIELD

[0001] The present application relates to the field of automation, in particular to an automatic turnover system of blood collection bags of blood stations and a turnover method thereof. BACKGROUND

[0002] Blood collection bags are used for extracting and storing a certain number of milliliters of human blood and are widely used in medicine. After being collected in scattered manner, the blood collection bags need to be uniformly put into blood stations for storage at a specified temperature, so an automatic turnover mechanism needs to be applied in blood stations to deal with the large amount of blood collection bag carrying work.

[0003] Chinese Patent Specification CN111498355A discloses a turntable type automatic blood storage device and access method. A center rotating shaft perpendicular to the ground is arranged in a refrigeration cabinet, the center rotating shaft is provided with a plurality of partition plates from top to bottom, a plurality of storage positions for placing blood bags are arranged between adjacent two partition plates, and a movable storage box is arranged on each storage position, and the blood bag is placed in the storage box. A set of movable grabbing components are used to realize the access of the blood bag, which occupies small space and has high space utilization. At the same time, the automatic access of the blood bag is realized, the access speed and accuracy of the blood bag are effectively improved, the storage environment of the blood bag is constant humidity, constant temperature and sterile, and the storage safety of the blood is improved.

[0004] The above-mentioned patent mainly solves the storage problem in the blood station, and pursues small volume and high space utilization. However, blood collection bags collected from different blood collection points have different collection times and different blood type attributes. These numerous blood collection bags need to be sorted as much as possible before being put into the warehouse, and this sorting must be completed in a large space laid horizontally. The prior art still lacks such a targeted automatic sorting turnover system. SUMMARY

[0005] The problem to be solved by the present application is to provide an automatic turnover system of blood collection bags of blood stations and a turnover method thereof, which provides a complete solution for the sorting and turnover of blood stations. The overall automation degree is high, the turnover mode at different stages is also suitable for different turned-over objects, and the overall design is reasonable and efficient.

[0006] To solve the above problems, the present application provides an automatic turnover system of blood collection bags of blood stations and a turnover method thereof. To achieve the above-mentioned purpose, the technical scheme adopted by the present application to solve its technical problems is:

[0007] Automatic turnover system of blood station blood collection bag, comprising: suction cup transfer mechanism, comprising a suction cup for adsorbing the top surface of the blood collection bag, the suction cup being connected with a parallel robot; blister tray, comprising a plurality of containing cells for placing the blood collection bag, the side vertical surface of the blister tray being provided with a surrounding beam, the outer wall of the surrounding beam being provided with a first recess; clamping turnover mechanism, comprising a pair of clamping jaws capable of moving towards or away from each other, the clamping jaws being inserted into the first recess, the clamping turnover mechanism being used for turnover and stacking of the blister tray with the blood collection bag; the bottom surface of the containing cell is provided with a hollow hole, the centroid of the bottom surface of the containing cell is not in contact with the hollow hole; the height of the surrounding beam is greater than the vertical thickness of the blood collection bag.

[0008] The beneficial effects of the above technical scheme are: the technical scheme provides a complete solution for sorting and turnover of blood stations in addition to blood collection bag storage. The overall automation degree is high, and the turnover mode at different stages is suitable for different turned-over objects. The overall design is reasonable and efficient.

[0009] Firstly, different specifications of blood collection bags collected from various places are transferred into the blister tray one by one, and the turnover mode of the suction cup is relatively gentle. After being transferred to the blister tray, the same specification is classified, which is convenient for batch turnover in the later stage and stacking. This is the first stage, and the main idea is sorting, followed by turnover.

[0010] Secondly, the clamping turnover mechanism clamps the blister tray by using the physical activity of the chuck, so as to realize batch turnover of the blood collection bag and improve the efficiency. The assembly mode of the clamping jaw and the blister tray is relatively firm, which is equivalent to the second stage, mainly for turnover.

[0011] Thirdly, the hollow hole of the blister tray is equivalent to penetrating the upper and lower surfaces of the blister tray. Under the premise that the blood collection bag will not fall off, it is not easy to be in a small volume sealed area when stacking, and the surfaces are not easy to be adhered to each other due to negative pressure when being split.

[0012] Finally, the thickness of the blister tray ensures that the vertical stacking is concave-convex matched, so as to avoid crushing the blood collection bag.

[0013] As a further improvement of the present application, the blister tray is divided into a plurality of containing cells by a partition rib, and the containing cells are arranged in a rectangular array; the top corner of the surrounding beam is provided with a first convex corner; the top of the surrounding beam is provided with a first convex table; the connecting lines between all the first convex corners of the same blister tray form a rectangle, and the connecting lines between all the first convex tables of the same blister tray form a diamond.

[0014] The beneficial effects of the above technical scheme are: the vertically stacked blister trays are limited by mutual clamping between the vertically adjacent blister trays. The first convex corner is to avoid horizontal displacement between each other, and the clamped first convex table also enhances the limiting effect.

[0015] As a further improvement of the present application, the clamping turnover mechanism comprises a mechanical arm, the mechanical arm is assembled with a horizontal plate through a flange seat, the lower surface of the horizontal plate is fixed with a linear cylinder, and the linear cylinder drives the clamping jaw; each clamping jaw is arranged with a plurality of protruding teeth in the same horizontal direction; each first recess contains a protruding tooth; and the protruding tooth is a cuboid.

[0016] The beneficial effects of the above technical scheme are that the linear cylinder provides opposite linear motion for the clamping jaw. The protruding teeth in the form of a cuboid have better limiting effect than the protruding teeth in the form of a cylinder or a hemisphere, and can limit the degree of freedom of rotation.

[0017] As a further improvement of the present application, the lower surface of the horizontal plate is fixed with a linear guide rail, a sliding block is movably assembled on the linear guide rail, and an extension plate is fixed on the sliding block; limit heads fixed with the horizontal plate are further arranged on both sides of the extension plate; the limit heads on both sides of the extension plate are coaxial and oppositely arranged bolts, the distance between the limit heads on both sides of the extension plate is greater than the thickness of the extension plate, and the axis of the bolt intersects the extension plate.

[0018] The beneficial effects of the above technical scheme are that the linear guide rail provides guidance for the movement of the clamping jaw. The limit heads limit the extreme position, thereby adapting to the clamping and loosening of the blister tray. The bolt can fine-tune the extreme position.

[0019] As a further improvement of the present application, the number of the suction pad transfer mechanism is an integer multiple of the number of the clamping turnover mechanism, a forklift tray is arranged beside the clamping turnover mechanism, and the clamping turnover mechanism stacks the blister tray with the blood collection bag on the forklift tray.

[0020] The beneficial effects of the above technical scheme are that one blister tray can store a plurality of blood collection bags, and one clamping turnover mechanism can turnover one blister tray at a time, so the relative turnover efficiency of one clamping turnover mechanism is several times that of the suction pad transfer mechanism.

[0021] As a further improvement of the present application, a gantry is further arranged between the suction pad transfer mechanism and the clamping turnover mechanism, and a horizontal linear module is arranged on the lower surface of the top of the gantry, and a photoelectric detector is arranged on the sliding seat of the horizontal linear module.

[0022] The beneficial effects of the above technical scheme are that the photoelectric detector moves with the horizontal linear module, can quickly sense the information of the blood collection bag on the blister tray, and detect whether the blood collection bag is loaded according to the requirements.

[0023] As a further improvement of the present application, the suction pad tray with the blood collection bag passes below the gantry, the photoelectric detector faces the blood collection bag in the blister tray, and the number of the photoelectric detectors is equal to the number of rows of the blood collection bags on the blister tray.

[0024] The beneficial effect of the above technical scheme is that the photoelectric detector can quickly sense the condition of a row of blood bags through automatic translation scanning.

[0025] As a further improvement of the application, the clamping turnover mechanism or gantry is further provided with a backing plate, the backing plate has a flat bottom surface in contact with the bottom surface of the blister tray, and the vertical thickness of the backing plate is greater than the thickness of the blister tray.

[0026] The beneficial effect of the above technical scheme is that the backing plate provides an intermediate object and an auxiliary tool. The complete flat bottom surface of the backing plate can be used as the bottom support of the blister tray, which is convenient to use when the strength of the blister tray itself is not enough.

[0027] As a further improvement of the application, the backing plate is made of metal, one edge of the backing plate is provided with a second recess for inserting the protruding teeth, and the top corner of the backing plate is provided with a second convex corner; and one edge of the backing plate is provided with a second convex boss.

[0028] The beneficial effect of the above technical scheme is that the backing plate is in close contact with the concave-convex of the blister tray, so the clamping effect is good.

[0029] The turnover method comprises the automatic turnover system of the blood station blood collection bag as above, and the method steps are as follows.

[0030] Step one, a plurality of suction cup transfer mechanisms are commonly arranged on the same conveying belt, and the conveying belt conveys a plurality of specifications of blood collection bags;

[0031] Step two, each suction cup transfer mechanism uses its own suction cup to adsorb and transfer the same specification of blood collection bag to the blister tray;

[0032] Step three, when the blister tray is filled with blood collection bags, the blister tray is horizontally conveyed and passes under the gantry, and the photoelectric detector of the gantry detects the number and specification of the blood collection bags on the blister tray;

[0033] Step four, the clamping turnover mechanism clamps the two side edges of the blister tray after passing out from the gantry, and stacks the blister tray on the forklift tray;

[0034] Step five, the empty blister tray is provided with a backing plate below, and the blister tray provided with the backing plate below is sequentially subjected to steps one, two, three and four;

[0035] Step six, the backing plates on the forklift tray are vertically and spacedly arranged, and the number of the blister trays on the forklift tray is greater than the number of the backing plates.

[0036] The beneficial effects of the above technical scheme are: the present turnover method is targeted for sorting and turnover, and sorting and turnover are carried out synchronously and have different focuses, and after grading processing, the same specification blood collection bags can be finally realized in group stacking, the occupied space is greatly reduced, and the uniformity is improved. The freedom degree of the gasket plate is high, and the relatively weak blister tray can be assisted, and the height of the stacking can be raised by improving the structural strength.

DETAILED DESCRIPTION

[0054] The content of the present application will be further described in detail below in combination with specific embodiments:

[0055] In order to achieve the purpose of the present application, the automatic turnover system of the blood collection bag of the blood station comprises: a suction pad transfer mechanism, which comprises a suction pad 2 for adsorbing and contacting the top surface of the blood collection bag 1, and the suction pad 2 is connected with a parallel robot 7; a suction plastic tray 11, which comprises a plurality of containing cells for placing the blood collection bags 1, and the side vertical surface of the suction plastic tray 11 has a surrounding beam, and the outer wall of the surrounding beam has a first recessed pit 11b; a clamping turnover mechanism, which comprises a pair of clamping jaws 12 capable of moving towards or away from each other, the clamping jaws 12 are inserted into the first recessed pit 11b, and the clamping turnover mechanism turns and stacks the suction plastic tray 11 with the blood collection bags 1;

[0056] As shown in Figure 9 , the bottom surface of the containing cell has a hollow hole 11a, and the centroid of the bottom surface of the containing cell is not in contact with the hollow hole 11a; the height of the surrounding beam is greater than the vertical thickness of the blood collection bag 1.

[0057] The beneficial effects of the above technical scheme are: the technical scheme provides a complete solution for sorting and turnover of blood bags other than storage of the blood bags by the blood collection bag storage device. The overall automation degree is high, and the turnover mode in different stages is suitable for different objects to be turned over, and the overall design is reasonable and efficient. First, different specifications of blood collection bags collected from various places are transferred to the suction tray one by one, and the turnover mode of the suction tray is relatively gentle. After being transferred to the suction tray, the blood collection bags are classified by the same specification, which is convenient for group turnover in the later stage and stacking. This is the first stage, and the main idea is sorting, and the second is turnover. Second, the clamping turnover mechanism clamps the suction tray by using a physical movable clamp, so that the batch turnover of the blood collection bags is realized, and the efficiency is improved. The assembly mode of the clamping jaw and the suction tray is relatively firm, which is equivalent to the second stage, and the main purpose is turnover. Third, the hollow hole shape of the suction tray is equivalent to penetrating the upper and lower surfaces of the suction tray. Under the premise that the blood collection bags will not fall off, the suction tray is not easy to be in a small volume sealed area when stacking, and the surfaces are not easy to be adhered to each other due to negative pressure when being split. Finally, the thickness of the suction tray ensures that the vertical stacking of the suction tray is concave-convex matched, so as to avoid crushing the blood collection bags.

[0058] In some other embodiments of the present application, the suction tray 11 is divided into a plurality of accommodation cells by the partition ribs 11e, and the accommodation cells are arranged in a rectangular array; the top corners of the surrounding beams are provided with first convex corners 11c; the top of the surrounding beam is provided with a first convex table 11d; the connecting lines between all the first convex corners 11c of the same suction tray 11 form a rectangle, and the connecting lines between all the first convex tables 11d of the same suction tray 11 form a diamond.

[0059] The beneficial effects of the above technical scheme are: the vertically stacked suction trays are limited by each other through clamping. The first convex corner is to avoid horizontal displacement between each other, and the clamped first convex table also enhances the limiting effect.

[0060] In some other embodiments of the present application, the clamping turnover mechanism includes a mechanical arm 9, the mechanical arm 9 is assembled with a horizontal plate 14 through a flange seat 13, the lower surface of the horizontal plate 14 is fixed with a linear cylinder 15, and the linear cylinder 15 drives the clamping jaw 12; a plurality of convex teeth 12a are arranged in the same horizontal direction for each clamping jaw 12; each first recess 11b accommodates a convex tooth 12a; as shown in Figure 11 The convex tooth 12a is a cuboid.

[0061] The beneficial effects of the above technical scheme are: the linear cylinder provides opposite linear motion for the clamping jaw. Compared with the cylindrical and hemispherical convex teeth, the limiting effect of the cuboid convex tooth is better, and the degree of freedom of rotation can be limited.

[0062] As shown in Figure 10As shown, in some other embodiments of the present invention, a linear guide rail 17 is fixed on the lower surface of the horizontal plate 14, a slider 16 is movably mounted on the linear guide rail 17, and an extension plate 19 is fixed on the slider 16; limiting heads 18 fixed to the horizontal plate 14 are also provided on both sides of the extension plate 19; the limiting heads 18 on both sides of the extension plate 19 are coaxial and oppositely arranged bolts, the distance between the limiting heads 18 on both sides of the extension plate 19 is greater than the thickness of the extension plate 19, and the extension line of the bolt's own axis intersects with the extension plate 19.

[0063] The beneficial effects of adopting the above technical solution are: the linear guide rail provides guidance for the movement of the gripper; the limiting head effectively restricts the extreme positions, thus adapting to the clamping and loosening of the blister tray; and the bolts allow for fine adjustment of these extreme positions.

[0064] like Figure 12 As shown, in some other embodiments of the present invention, the number of suction cup transfer mechanisms is an integer multiple of the number of clamping and turnover mechanisms, such as... Figure 7 As shown, a forklift pallet 10 is provided next to the clamping and turnover mechanism. The clamping and turnover mechanism stacks the blister pallet 11 with blood collection bags 1 on the forklift pallet 10.

[0065] The beneficial effects of adopting the above technical solution are: because a blister tray can store multiple blood collection bags, and the clamping and turnover mechanism can turn over a blister tray at a time, the relative turnover efficiency of a clamping and turnover mechanism is several times that of the suction cup transfer mechanism.

[0066] In some other embodiments of the present invention, a gantry 20 is provided between the suction cup transfer mechanism and the clamping and turnover mechanism. A horizontal linear module 22 is provided on the lower surface of the top of the gantry 20, and a photodetector 21 is provided on the slide of the horizontal linear module 22.

[0067] The beneficial effects of adopting the above technical solution are: the photoelectric detector moves with the horizontal linear module, which can quickly sense the information of the blood collection bags on the blister tray and detect whether the blood collection bags are loaded as required.

[0068] like Figure 13 As shown, in some other embodiments of the present invention, a blister tray 11 containing blood collection bags 1 passes under the gantry 20, and a photodetector 21 faces the blood collection bags 1 in the blister tray 11. The number of photodetectors 21 is equal to the number of rows of blood collection bags 1 on the blister tray 11.

[0069] The beneficial effect of adopting the above technical solution is that, as the photoelectric detector automatically moves and scans, each photoelectric detector can quickly sense the condition of a row of blood bags.

[0070] like Figure 12 , Figure 13As shown in the drawings, in some embodiments of the present application, the clamping turnover mechanism or gantry is further provided with a backing plate 23, which has a flat bottom surface 23a in contact with the bottom surface of the blister tray 11, and the vertical thickness of the backing plate 23 is greater than the thickness of the blister tray 11.

[0071] The beneficial effect of the above technical solution is that the backing plate provides an intermediate object and an auxiliary tool. The complete flat bottom surface of the backing plate can be used as the bottom support of the blister tray. It is convenient to use in the case where the strength of the blister tray itself is not enough.

[0072] As shown in the drawings, Figure 13 , Figure 14 As shown in the drawings, in some embodiments of the present application, the backing plate 23 is made of metal, one edge of the backing plate 23 is provided with a second recess 23b for inserting the protruding teeth 12a, and the top corner of the backing plate 23 is provided with a second convex corner 23c; one edge of the backing plate 23 is provided with a second convex boss 23d.

[0073] The beneficial effect of the above technical solution is that the backing plate is in close contact with the concave-convex of the blister tray, so the clamping effect is good.

[0074] In some embodiments of the present application, the turnover method includes the automatic turnover system of the blood station blood collection bag as above, and the method steps are as follows: step one, a plurality of suction cup transfer mechanisms are commonly arranged on the same conveying belt, and the conveying belt conveys a plurality of specifications of blood collection bags 1; step two, each suction cup transfer mechanism uses its own suction cup 2 to adsorb and transfer the same specification of blood collection bags 1 to the blister tray 11; step three, when the blister tray 11 is full of blood collection bags 1, the blister tray 11 is horizontally conveyed and passes through the gantry 20, and the photoelectric detector 21 of the gantry 20 detects the number and specification of the blood collection bags 1 on the blister tray; step four, the clamping turnover mechanism clamps the two side edges of the blister tray 11 after passing through the gantry 20, and stacks the blister tray 11 on the forklift tray 10; step five, the empty blister tray 11 is buckled with a backing plate 23 below, and the blister tray 11 buckled with the backing plate 23 below is sequentially subjected to steps one, two, three, and four; step six, the backing plates 23 on the forklift tray 10 are vertically and spaced apart, and the number of blister trays 11 on the forklift tray 10 is greater than the number of backing plates 23.

[0075] The beneficial effect of the above technical solution is that the turnover method is targeted for sorting and turnover, and sorting and turnover are performed synchronously and have different focuses. After grading, the same specification of blood collection bags can be finally stacked in groups, greatly reducing the space occupied and improving the uniformity. The backing plate has high degree of freedom, can assist the relatively weak blister tray, and can also increase the stacking height by improving the structural strength.

[0076] The suction cup transfer mechanism comprises: a suction cup 2, a top plate 3 is fixed with a plurality of downwardly open suction cups 2, the suction cup 2 is in suction contact with a blood collection bag 1, the top surface and the bottom surface of the blood collection bag 1 comprise an outer arch piece 1a; a downward needle 5 penetrates the centroid of the top plate 3, the downward needle 5 has a lifting degree of freedom along the axis thereof, the downward needle 5 pierces the blood collection bag 1 when it is extended forward, and the downward needle 5 itself has a hollow suction pipe; the number of the suction cups 2 is six, and the two suction cups 2 on the two sides of the downward needle 5 are arranged in mirror symmetry; the axes of the two suction cups 2 on the two adjacent sides of the downward needle 5 are parallel to the axis of the downward needle 5, and are coincided on a same spatial longitudinal section; in addition to the two suction cups 2 on the two adjacent sides of the downward needle 5, the other four suction cups 2 are arranged in mirror symmetry on the two sides of the spatial longitudinal section, and the distance between the suction cup 2 and the spatial longitudinal section gradually decreases from the root to the opening.

[0077] The beneficial effects of the above technical solution are: the suction cup structure of the blood collection bag is designed, and the suction cup is more suitable for the shape and hardness of the blood collection bag. It also has a sampling detection function. First, part of the suction cup is vertical, and part of it is appropriately tilted, which adapts to the slightly convex shape of the blood collection bag after it is filled with blood, so that the blood collection bag is not easy to wrinkle and deform when it is suctioned and circulated. Second, the downward needle has a telescopic degree of freedom, when it is normally circulated, the downward needle is retracted and does not interfere with the blood collection bag; when temporary sampling is needed, the downward needle is extended forward to sample the blood in the blood collection bag. The sampling mechanism and the suction cup circulation mechanism are integrated, which greatly improves the sampling efficiency and reduces the size of the equipment.

[0078] Finally, the suction cups on the two adjacent sides of the downward needle are vertically downward, and the suction force of the suction cups can resist the force when the downward needle is pierced downward to avoid the blood collection bag from loosening.

[0079] In other embodiments of the present application, the two ends of the blood collection bag 1 comprise olive-shaped pieces 1b, which are integrally connected with the outer arch pieces 1a of the top surface and the bottom surface of the blood collection bag 1; the outer walls of the blood collection bag 1 at the outer arch pieces 1a are all convex curved surfaces; the highest limit position of the bottom of the downward needle 5 is higher than the outer arch piece 1a of the top surface of the blood collection bag 1, and the lowest limit position of the bottom of the downward needle 5 is lower than the outer arch piece 1a of the top surface of the blood collection bag 1 and higher than the outer arch piece 1a of the bottom surface of the blood collection bag 1.

[0080] The beneficial effects of the above technical solution are: the overall shape of the blood collection bag is close to a rectangle from the top view, and the top surface and the bottom surface are both convex curved surfaces. The action range of the blood collection bag ensures that it only samples a small amount of milliliter, does not pierce the entire blood collection bag, and does not contaminate the work station.

[0081] In other embodiments of the present application, the bottom of the downward needle 5 has a conical part 5a, and the side surface of the downward needle 5 has a side hole 5b in communication with the suction pipe thereof.

[0082] The beneficial effect of the above technical scheme is that the conical part ensures the sharpness of the downward needle, and the side hole is not easily blocked by the thin film shell of the blood collection bag.

[0083] In some other embodiments of the present application, the top plate 3 is composed of three straight strips 3a connected at obtuse angles, and each straight strip 3a is equipped with two suction cups 2.

[0084] The beneficial effect of the above technical scheme is that the shape of the top plate itself reduces the difficulty of assembling the suction cup, and the suction cup only needs to ensure the vertical assembly of the root part to ensure the different angles of different suction cups with the plumb line.

[0085] In some other embodiments of the present application, the top plate 3 is composed of three straight strips 3a connected at obtuse angles, and each straight strip 3a is equipped with two suction cups 2.

[0086] The beneficial effect of the above technical scheme is that the direction of the photoelectric sensor is oblique, and this oblique sensing path can sense whether the suction cup is attached to the blood collection bag at this moment, and can also sense whether the downward needle is extended.

[0087] In some other embodiments of the present application, the upper surface of the top plate 3 is assembled with a parallel robot 7 through a flange seat, the top plate 3 is provided with a hose 4, the hose 4 is connected with a vacuum generator, and the hose 4 is in air communication with the suction cup 2.

[0088] The beneficial effect of the above technical scheme is that the suction cup uses negative pressure to adsorb or relax the blood collection bag.

[0089] In some other embodiments of the present application, the suction cup 2 is made of silica gel, and the outer wall of the suction cup 2 is arranged with a plurality of annular ribs 2a along the axial direction.

[0090] The beneficial effect of the above technical scheme is that the part between adjacent annular ribs is relatively weak in structural strength and can be compressed, so the suction cup has a compression buffering effect.

[0091] In some other embodiments of the present application, the length direction of the straight strip 3a is parallel to the length direction of the blood collection bag 1, and the height of the bottom opening of the suction cup 2 of the two straight strips 3a on both sides is lower than the height of the bottom opening of the suction cup 2 of the straight strip 3a in the middle.

[0092] The beneficial effect of the above technical scheme is that the bottom opening of the suction cup can adapt to the convex surface of the top surface of the blood collection bag.

[0093] In some other embodiments of the present application, a metal sheet cover is arranged on the top plate 3, and the metal sheet cover is used for the hose 4 to pass through.

[0094] The beneficial effect of the above technical scheme is that the metal sheet cover can make the upper surface of the whole suction cup group more smooth, and avoid dirt.

[0095] Figure 9 The blister tray 11 in the blood collection bag 1 is not fully filled with the plasma bag 1, so that the hollow hole 11a can be clearly displayed.

[0096] The outer arch piece 1a and the olive-shaped piece 1b of the blood collection bag 1 are made of PVC material.

[0097] The space longitudinal section is a virtual space plane, which is set for the convenience of expressing the relative position relationship of each component.
