Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, and specifically, to an automatic laser marking device for blood collection tubes. Background Art

[0002] The workload of hospital blood tests continues to grow, and a large number of blood specimens need to be processed every day. Since most of the management work of blood collection tubes still relies on manual labor, and there are problems such as heavy workload, low efficiency, and easy errors, the traditional manual management method of blood collection tubes can no longer meet the growing demand.

[0003] Medical blood collection tubes usually have marking information printed on the tube body so that medical staff can accurately identify and manage them. Currently, the commonly used marking methods include: manually pasting labels on the outside of blood collection tubes, automatic labeling, and directly printing marking information on blood collection tubes through printing technology.

[0004] First of all, manually pasting labels will greatly increase the workload of medical staff, which not only seriously wastes the already scarce medical resources but also easily leads to the loss and error of information. Although automatic labeling and printing markings reduce the workload of medical staff, they are prone to falling off and are also easily rubbed or contaminated and fall off, resulting in unclear or lost marking information. The most important thing is that the methods of automatic labeling and printing markings may not be clearly visible for a long time and need to be replaced or maintained regularly, increasing the management cost and workload and causing waste of various resources.

[0005] In the field of medical care related to life and health, the requirements for accuracy and safety are naturally extremely high. It is not difficult to see that the above-mentioned marking methods all have their own deficiencies and limitations, which will seriously affect the accuracy and safety of the medical system. In addition, the existing automatic labeling and printing equipment currently available is relatively large in volume, relatively bulky as a whole, and difficult to transport. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is: to provide an automatic laser marking device for blood collection tubes, which can automatically perform laser marking on blood collection tubes, avoid the problems brought by the above-mentioned labeling and printing, and integrate all components into one body, with a small volume and being lightweight, which is conducive to transportation.

[0007] The utility model provides an automatic laser marking device for blood collection tubes, including:

[0008] A support frame, a hopper, a material receiving mechanism, a laser marking mechanism, and a collection mechanism;

[0009] The hopper, the material receiving mechanism and the collecting mechanism are fixedly arranged in the support frame from top to bottom in sequence; the hopper is used for placing round tubes in the front-back direction, and the upper and lower ends of the hopper are respectively provided with a feed inlet and a discharge outlet, and the discharge outlet is in a strip structure matching the shape of the round tube, so that only one round tube can be discharged from the discharge outlet each time;

[0010] The material receiving mechanism includes a first material receiving rack fixed on the support frame, a second material receiving rack fixed on the support frame and arranged at an interval from the first material receiving rack, a driving motor fixed on the first material receiving rack, a rotating shaft fixed at one end of the driving end of the driving motor and arranged in the front-back direction, a first transmission turntable and a second transmission turntable respectively fixed on both axial sides of the rotating shaft; the other end of the rotating shaft is rotatably connected with the second material receiving rack; the rotating shaft, the first transmission turntable and the second transmission turntable are all located directly below the discharge outlet; a plurality of pairs of placement grooves for accommodating round tubes are circumferentially arranged at intervals on the outer edges of the first transmission turntable and the second transmission turntable, and the distance between the first transmission turntable and the second transmission turntable is less than the length of the round tube, so that the round tube can fall into a pair of placement grooves, and both ends of the round tube are outside the placement grooves and are conveyed according to the rotation of the rotating shaft; the distance between the outer edges of the first transmission turntable and the second transmission turntable and the discharge outlet is less than the diameter of the round tube;

[0011] The laser marking mechanism is fixed on the support frame, and the emitting end of the laser marking mechanism is aligned with the tube body of the round tube on the material receiving mechanism to perform laser marking treatment on the round tube on the material receiving mechanism;

[0012] The collecting mechanism is connected to the lower ends of the first transmission turntable and the second transmission turntable and is used for collecting the round tubes that fall out of the placement grooves during the rotation of the rotating shaft.

[0013] Compared with the prior art, the present application has the following advantages: when placing the round tubes to be processed in the hopper, since only one round tube can be discharged from the discharge outlet each time, each round tube can fall into the placement groove to form a placement. As the rotating shaft rotates, the round tube can be conveyed along the rotation of the rotating shaft. During the conveying process, the laser marking mechanism performs laser marking treatment on the round tube and then the round tube falls into the collecting mechanism for collection, avoiding the problems brought by the above-mentioned labeling and printing. Moreover, the components such as the hopper, the material receiving mechanism, the laser marking mechanism and the collecting mechanism are integrated into one body, with a small volume, which is beneficial to light weight and transportation.

[0014] In a possible implementation manner, the material receiving mechanism further includes a round tube turntable coaxially fixed on the rotating shaft. The round tube turntable is located between the first material receiving rack and the first transmission turntable. A plurality of elastic turntables corresponding to each pair of placement grooves in position are evenly distributed along the circumferential direction on the inner surface of the round tube turntable. Each elastic turntable is rotatably connected to the inner circumferential surface of the round tube turntable, and a clamping groove for the end of the round tube to be clamped into is formed on each elastic turntable;

[0015] A motor is fixed on the second material receiving rack, and a spring pressing piece is fixed on the driving end of the motor. When the material receiving mechanism rotates, the other end of the round tube located on the material receiving mechanism can move to the position of the spring pressing piece;

[0016] A section of pressing track protruding is fixed on the inner side wall of the second material receiving rack. The pressing track extends along the running track of the other end of the round tube, and the protruding length of the pressing track gradually increases along the running track of the other end of the round tube; the spring pressing piece is located at the end of the pressing track;

[0017] When the material receiving mechanism rotates, the other end of the round tube located on the material receiving mechanism abuts against the pressing track, and as the protruding length of the pressing track changes, one end of the round tube is clamped into the card slot; when one end of the round tube rotates out of the pressing track along with the material receiving mechanism, the other end of the round tube abuts against the spring pressing piece, so that the rotation of the driving end of the motor can drive the spring pressing piece, the round tube and the elastic turntable to rotate in sequence.

[0018] Compared with the prior art, adopting the above technical solution can, when the round tube falls into the placement groove, the pressing track can push one end of the round tube into the card slot, and the rotation of the driving end of the motor can drive the spring pressing piece, the round tube and the elastic turntable to rotate in sequence, that is, the round tube can rotate circumferentially while being transported, which is convenient for laser marking processing.

[0019] In a possible implementation manner, the laser marking mechanism includes a pair of lifting devices, a lifting rod with a U-shaped structure, a horizontal movement driving device and a laser marking device; both lifting devices are fixed on the support frame on one side of the material receiving mechanism and are arranged at intervals; both ends of the open side of the lifting rod are respectively arranged on the two lifting devices in a liftable manner to realize vertical lifting; the cross bar on the closed side of the lifting rod is arranged parallel to the rotating shaft, the horizontal movement driving device is movably arranged on the cross bar to realize horizontal movement back and forth, and the laser marking device is fixed on the horizontal movement driving device and the emitting end is aligned with the round tube on the material receiving mechanism.

[0020] Compared with the prior art, adopting the above technical solution can make the laser marking device move up and down and back and forth to perform laser marking on the body of the round tube, and effectively perform laser marking processing.

[0021] In a possible implementation, the collection mechanism includes a storage box and a storage frame; openings and an outlet are respectively provided at the upper and lower ends of the storage box. The openings are connected to the lower ends of the first transfer turntable and the second transfer turntable, and the outlet is connected to the storage frame; the openings are in a strip structure matching the shape of the circular tube, and the outlet is in a circular structure matching the shape of the end of the circular tube; the openings are inclined towards the outlet to form an arc-shaped guiding surface; a plurality of limiting plates parallel to each other and equidistantly arranged in the left-right direction are fixed in the storage frame, and a receiving channel for connecting with the outlet and placing the circular tube is formed between adjacent limiting plates, and the distance between adjacent limiting plates is smaller than the diameter of the circular tube; during the rotation of the rotating shaft, the other end of the circular tube comes out, thereby driving one end of the circular tube out of the card slot, so that the circular tube falls into the storage box through the opening, and slides towards the outlet through the arc-shaped guiding surface and lands on the receiving channel and abuts against the upper ends of two adjacent limiting plates.

[0022] Compared with the prior art, adopting the above technical solution enables the storage box to collect the circular tubes that come out of the placement groove through the opening, and enables the circular tubes to fall into the storage frame through the outlet, which is convenient for collection after laser marking and finally for the staff to take. Moreover, the arc-shaped guiding surface can guide the circular tubes to the outlet and vertically fall into the storage frame, which is not easy to cause blockage and is not easy to break the circular tubes.

[0023] In a possible implementation, there is a height difference between the front and rear ends of the storage frame, so that one end of all the receiving channels in the length direction faces downward and the other end faces upward; when the other end of the circular tube falls out of the opening, it lands on the receiving channel and slides towards the lower end of the receiving channel, thereby driving one end of the circular tube to fall out of the opening and land on the upper side of the receiving channel.

[0024] Compared with the prior art, adopting the above technical solution enables the other end of the circular tube to first land on the receiving channel, then vertically fall and the other end slide towards the lower end of the receiving channel for placement, and one end of the circular tube falls out of the opening and lands on the upper side of the receiving channel. It is equivalent to that when the whole circular tube falls on the receiving channel, the two ends change directions. This can prevent the circular tubes from being broken and is also convenient for the staff to take. The receiving channels are formed by the spaced limiting plates, reducing the material used for the storage frame and making the entire collection mechanism lighter.

[0025] In a possible implementation, the collection mechanism further includes a slide rail, a screw motor, a screw rod and a threaded block; the slide rail is fixed on the support frame and arranged in the left-right direction, the screw motor is fixed at one end of the slide rail and the driving end of the screw motor faces the slide rail, the screw rod is fixed on the driving end of the screw motor, the threaded block is threadedly connected to the screw rod and the threaded block is slidably connected in the slide rail, and the threaded block is also fixed to the front end of the storage frame; when the screw motor operates, it drives the screw rod and the storage frame to reciprocate along the slide rail in sequence.

[0026] Compared with the prior art, adopting the above technical solution can make the storage box reciprocate along the slide rail. In this way, when a certain accommodation channel is full, the empty accommodation channel can be moved to connect with the outlet, so that the accommodation channels can be filled in sequence.

[0027] In a possible implementation manner, a support rod is fixed to the lower end of the storage box, and a universal wheel is arranged at the lower end of the support rod.

[0028] Compared with the prior art, the support rod adopting the above technical solution can effectively provide a supporting force for the storage box, making it more stable, and the universal wheel can enable the storage box to effectively move along with the movement of the lead screw.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It is easy to understand that the circular tube 100 in the present application, that is, the blood collection tube mentioned in the background art. It should also be noted that the present application needs to be externally connected to a control terminal, such as a computer. That is, the feeding mechanism 3, the laser marking mechanism 4, and the collection mechanism 5 all need to be communicatively connected to the control terminal to realize the control of the feeding mechanism 3, the laser marking mechanism 4, and the collection mechanism 5 through the control terminal. This belongs to the prior art and will not be elaborated in the present application; one end of the following circular tube 100 all refers to the end close to the first transfer turntable 35, and the other end of the circular tube 100 all refers to the end close to the second transfer turntable 36.

[0042] As shown in Figure 1 FIG., Figure 2 FIG., Figure 3 and FIG.

[0043] The embodiments of the present application disclose an automatic device for laser marking of blood collection tubes, including:

[0044] The hopper 2, the material receiving mechanism 3 and the collecting mechanism 5 are fixedly arranged in the support frame 1 from top to bottom in sequence; the hopper 2 is used for placing the round tubes 100 in the front-back direction. The upper and lower ends of the hopper 2 are respectively provided with a feed inlet 21 and a discharge outlet 22. The discharge outlet 22 is in a strip structure matching the shape of the round tube 100, so that only one round tube 100 can be discharged from the discharge outlet 22 each time.

[0045] The material receiving mechanism 3 includes a first material receiving rack 31 fixedly arranged on the support frame 1, a second material receiving rack 32 fixedly arranged on the support frame 1 and spaced from the first material receiving rack 31, a driving motor 33 fixedly arranged on the first material receiving rack 31, a rotating shaft 34 with one end fixedly arranged on the driving end of the driving motor 33 and arranged in the front-back direction, a first transmission turntable 35 and a second transmission turntable 36 respectively fixedly arranged on both axial sides of the rotating shaft 34; the other end of the rotating shaft 34 is rotatably connected to the second material receiving rack 32; the rotating shaft 34, the first transmission turntable 35 and the second transmission turntable 36 are all located directly below the discharge outlet 22; a plurality of pairs of placing grooves 30 for accommodating the round tubes 100 are circumferentially arranged at intervals on the outer edges of the first transmission turntable 35 and the second transmission turntable 36, and the distance between the first transmission turntable 35 and the second transmission turntable 36 is less than the length of the round tube 100, so that the round tube 100 can fall into a pair of placing grooves 30, and both ends of the round tube 100 are outside the placing grooves 30 and are conveyed according to the rotation of the rotating shaft 34; the distance between the outer edges of the first transmission turntable 35 and the second transmission turntable 36 and the discharge outlet 22 is less than the diameter of the round tube 100.

[0046] The laser marking mechanism 4 is fixedly arranged on the support frame 1, and the emitting end of the laser marking mechanism 4 is aligned with the tube body of the round tube 100 on the material receiving mechanism 3 to perform laser marking treatment on the round tube 100 on the material receiving mechanism 3.

[0047] The collecting mechanism 5 is connected to the lower ends of the first transmission turntable 35 and the second transmission turntable 36, and is used for collecting the round tubes 100 that fall out of the placing grooves 30 during the rotation of the rotating shaft 34.

[0048] In this embodiment, the support frame 1 is a vertically arranged cuboid frame structure. Those skilled in the art can flexibly adjust the structure of the support frame 1 according to actual situations. In order to make the support frame 1 have higher strength, a metal support frame 1, such as stainless steel, can be used. The discharge outlet 22 of the hopper 2 is in a rectangular structure consistent with the shape of the round tube 100, and the diameter of the discharge outlet 22 is slightly larger than the diameter of the round tube 100, so that only one round tube 100 can be discharged horizontally from the discharge outlet 22 each time. As shown in the attached Figure 2 As shown, the driving motor 33 is fixed on the outer side wall of the first material receiving rack 31 through a fixed piece structure, and the driving end passes through the first material receiving rack 31. As shown in the attached Figure 2 , attached Figure 3 , attached Figure 4 and attachedFigure 5 As shown, the first transfer turntable 35 and the second transfer turntable 36 are circular, and C-shaped placement grooves 30 are evenly opened in the circumferential direction. As shown in the appendix Figure 3 As shown, when the placement groove 30 is aligned with the discharge port 22, the round tube 100 discharges from the discharge port 22, and both sides in the length direction of the round tube 100 fall into two placement grooves 30 respectively. When the placement groove 30 is not aligned with the discharge port 22, the round tube 100 at the discharge port 22 abuts against the outer peripheral edges of the first transfer turntable 35 and the second transfer turntable 36; during use, the round tube 100 to be processed is placed in the hopper 2. Since the discharge port 22 only discharges one round tube 100 each time, each round tube 100 can fall into the placement groove 30 to form a placement. As the rotating shaft 34 rotates, the round tube 100 can be conveyed along the rotation of the rotating shaft 34. During the conveying process, the laser marking mechanism 4 performs laser marking treatment on the round tube 100, avoiding the problems brought by the above-mentioned labeling and printing. Moreover, each component of the hopper 2, the material receiving mechanism 3, the laser marking mechanism 4, and the collection mechanism 5 is integrated into one body, with a small volume, which is beneficial to lightweight and transportation.

[0049] As shown in the appendix Figure 4 and the appendix Figure 5 as well as the appendix Figure 6 As shown, in some embodiments, the material receiving mechanism 3 further includes a round tube turntable 37 coaxially fixed on the rotating shaft 34. The round tube turntable 37 is located between the first material receiving frame 31 and the first transfer turntable 35. A plurality of elastic turntables 371 corresponding to the positions of each pair of placement grooves 30 are evenly distributed on the inner surface of the round tube turntable 37 in the circumferential direction. Each elastic turntable 371 is rotatably connected to the inner circumferential surface of the round tube turntable 37, and a clamping groove 3711 for one end of the round tube 100 to be inserted is opened on each elastic turntable 371;

[0050] A motor 38 is fixed on the second material receiving frame 32, and a spring pressing piece 381 is fixed at the driving end of the motor 38. When the material receiving mechanism 3 rotates, the other end of the round tube 100 located on the material receiving mechanism 3 can move to the position of the spring pressing piece 381;

[0051] A section of protruding pressing track 321 is fixed on the inner side wall of the second material receiving frame 32. The pressing track 321 extends along the running track of the other end of the round tube 100, and the protruding length of the pressing track 321 gradually increases along the running track of the other end of the round tube 100; the spring pressing piece 381 is located at the end of the pressing track 321;

[0052] When the material receiving mechanism 3 rotates, the other end of the circular tube 100 located on the material receiving mechanism 3 abuts against the pressing track 321, and as the protruding length of the pressing track 321 changes, one end of the circular tube 100 is snapped into the card slot 3711; when one end of the circular tube 100 rotates out of the pressing track 321 along with the material receiving mechanism 3, the other end of the circular tube 100 abuts against the spring pressing piece 381, so that the rotation of the driving end of the motor 38 can drive the spring pressing piece 381, the circular tube 100 and the elastic turntable 371 to rotate in sequence.

[0053] In this embodiment, the pressing track 321 is located on the inner side wall of the second material receiving frame 32, on the side close to the laser marking mechanism 4, and is located at the position where the circular tube 100 moves from the highest section to the middle section of the material receiving mechanism 3. Because if the circular tube 100 is disengaged in the lower section, it is not conducive to laser marking. The motor 38 is fixed to the outer side wall of the second material receiving frame 32 through a fixing piece structure, and the driving end passes through the second material receiving frame 32. The elastic turntable 371 is made of elastic rubber and is rotatably connected to the inner peripheral surface of the circular tube turntable 37 through a bearing structure. The pressing track 321 has an arc-shaped structure as shown in the appendix Figure 6 The arc-shaped structure matches the movement path of the other end of the circular tube 100 from the highest section to the middle section of the material receiving mechanism 3, which can ensure that one end of the circular tube 100 is pushed into the card slot 3711. The depth of the card slot 3711 is relatively shallow and can be set in millimeters. In this way, only a small part of one end of the circular tube 100 can be snapped into the card slot 3711 and tightly fit with its slot wall. At the same time, it can also effectively disengage along with the disengagement of the other end; when the driving end of the motor 38 rotates, the circular tube 100 itself also makes a circumferential rotation, which is convenient for laser marking processing.

[0054] As shown in the appendix Figure 2As shown, in some embodiments, the laser marking mechanism 4 includes a pair of lifting devices 41, a lifting rod 42 with a U-shaped structure, a horizontal movement driving device 43, and a laser marking device 44; both of the two lifting devices 41 are fixed on the support frame 1 on one side of the material receiving mechanism 3 and are arranged at intervals; both ends of the open side of the lifting rod 42 are respectively arranged on the two lifting devices 41 in a liftable manner to achieve vertical lifting; the cross bar 421 on the closed side of the lifting rod 42 is arranged parallel to the rotating shaft 34, the horizontal movement driving device 43 is movably arranged on the cross bar 421 to achieve horizontal movement in the front-rear direction, and the laser marking device 44 is fixed on the horizontal movement driving device 43 and the emitting end is aligned with the circular tube 100 on the material receiving mechanism 3. The laser marking device 44 can perform laser marking on the body of the circular tube 100 through the up-and-down movement of the lifting rod 42 and the movement in the front-rear direction through the horizontal movement driving device 43, and the emitting end of the laser marking device 44 is aligned with the upper half of the material receiving mechanism 3. Since the circular tube 100 in the lower half of the material receiving mechanism 3 is likely to come out, the laser marking work must be completed in the upper half. Of course, those skilled in the art can flexibly adjust the emitting end according to the actual situation so that the emitting end effectively performs laser marking treatment on the body of the circular tube 100; since the laser marking device 44 is a prior art, it will not be elaborated in this application.

[0055] As shown in the attached Figure 2 and the attached Figure 7As shown, in some embodiments, the collection mechanism 5 includes a storage box 51 and a storage frame 52; openings 511 and an outlet 512 are respectively provided at the upper and lower ends of the storage box 51. The opening 511 is connected to the lower ends of the first transfer turntable 35 and the second transfer turntable 36, and the outlet 512 is connected to the storage frame 52. The opening 511 has a strip-shaped structure matching the shape of the circular tube 100, and the outlet 512 has a circular structure matching the shape of the end of the circular tube 100. The opening 511 is inclined towards the outlet 512 to form an arc-shaped guiding surface 513. A plurality of limiting plates 521 that are parallel to each other and equally spaced in the left-right direction are fixed in the storage frame 52. A receiving channel 5211 for connecting with the outlet 512 and placing the circular tube 100 is formed between adjacent limiting plates 521, and the distance between adjacent limiting plates 521 is smaller than the outer diameter of the circular tube 100. During the rotation of the rotating shaft 34, the other end of the circular tube 100 comes out, thereby driving one end of the circular tube 100 out of the card slot 3711, so that the circular tube 100 falls into the storage box 51 through the opening 511, and slides towards the outlet 512 through the arc-shaped guiding surface 513 and lands on the receiving channel 5211 and abuts against the upper ends of two adjacent limiting plates 521. In this embodiment, the storage box 51 collects the circular tubes 100 that come out of the placement groove 30 through the opening 511, and allows the circular tubes 100 to fall into the storage frame 52 through the opening 511, which is convenient for collection after laser marking and finally for the staff to take. Moreover, the arc-shaped guiding surface 513 can guide the circular tubes 100 to the outlet 512 and vertically fall into the storage frame 52, which is not easy to cause blockage and not easy to break the circular tubes 100. And the receiving channel 5211 is formed by the spaced limiting plates 521, reducing the material used for the storage frame 52, and making the entire collection mechanism 5 lightweight.

[0056] A height difference is provided between the front and rear ends of the storage frame 52, so that one end in the length direction of all the receiving channels 5211 faces downward and the other end faces upward. When the other end of the circular tube 100 falls out of the opening 511, it lands on the receiving channel 5211 and slides towards the lower end of the receiving channel 5211, thereby driving one end of the circular tube 100 to fall out of the opening 511 and land on the upper side of the receiving channel 5211. In this embodiment, the storage frame 52 is arranged at an inclination of about 45° relative to the horizontal plane. The other end of the circular tube 100 first lands on the receiving channel 5211, then vertically falls and the other end slides towards the lower end of the receiving channel 5211 for placement, and one end of the circular tube 100 falls out of the opening 511 and lands on the upper side of the receiving channel 5211. It is equivalent to that when the whole circular tube 100 falls on the receiving channel 5211, the two ends change directions. This can prevent the circular tubes 100 from being broken and is also convenient for the staff to take.

[0057] Compared with the prior art, adopting the above technical solution enables the other end of the round tube 100 to first fall on the receiving channel 5211, and then slide to the lower end of the receiving channel 5211 after vertically dropping, and one end of the round tube 100 falls out from the opening 511 and lands on the upper side of the receiving channel 5211. It is equivalent to changing the directions of both ends when the whole round tube 100 falls on the receiving channel 5211. This can prevent the round tube 100 from being damaged and is also convenient for the staff to pick up. The receiving channel 5211 is formed by the spaced limiting plates 521, reducing the material used for the storage frame 52, and making the entire collection mechanism 5 lightweight.
