Description

Technical Field

[0001] The present invention specifically relates to a cache release device for an intelligent receipt system of vacuum test tube specimens. Background Art

[0002] At present, the automation of the specimen testing and inspection process has become a trend in medical institutions. Test tubes are essential containers for specimen inspection. Nowadays, most hospitals and various inspection institutions have established a hospital information system (HIS) and a laboratory information system (LIS). When medical staff collect blood or other fluid samples, they need to paste labels with patient information on vacuum blood collection tubes or other fluid sample test tubes so that the samples can be effectively identified during the laboratory inspection process.

[0003] Existing test tube cache release devices have two technical drawbacks: 1) A platform step + a flat surface of a synchronous belt are used to support the tube cap edge. The motor drives the synchronous belt to move. When the flat surface of the flat belt moves, it will drive the specimen tube to move. This method has many parts and a high manufacturing cost; 2) The interception mechanism drives a gear through a small reduction motor. There are two micro racks on both sides of the gear. The forward and reverse rotation of the motor drives a telescopic movement to control the release of the specimen. The stroke of this micro telescopic structure is limited by the structure to forcibly stop the motor, which will cause damage to the motor and a short service life. Summary of the Invention

[0004] In view of the above defects, the present invention provides a cache release device for an intelligent receipt system of vacuum test tube specimens, which can automatically extract test tubes and make the test tubes queue up and be cached in an orderly manner.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A cache release device for an intelligent receipt system of vacuum test tube specimens includes a base. A spare tube bin, a lifting mechanism, a chute mechanism, an interception mechanism, a launching pipe, and a tube pressing mechanism are arranged on the base. The spare tube bin is arranged on one side of the base and is used for placing vacuum test tubes. The lifting mechanism is arranged on the base and extends into the spare tube bin, and is used for extracting the vacuum test tubes in the spare tube bin. The chute mechanism is arranged on the top of the base and on one side of the lifting mechanism, and is used for receiving the vacuum test tubes extracted by the lifting mechanism and transporting and caching the vacuum test tubes. The interception mechanism is arranged on the chute mechanism and is used for intercepting the vacuum test tubes transported by the chute mechanism at multiple levels, so that the vacuum test tubes slide down one by one. The launching pipe is arranged on the side of the base and corresponds to the chute mechanism, and is used for receiving the vacuum test tubes that slide down one by one in the chute mechanism. The tube pressing mechanism is arranged at the lower end of the launching pipe and is used for preventing or releasing the vacuum test tubes in the launching pipe from falling and for pressing and fitting the labels on the vacuum test tubes again.

[0007] Preferably, the lifting mechanism includes a lifting motor, a connecting rod swing arm, a slide rail assembly, a tube lifting plate, a baffle plate, and a transition plate. The lifting motor is arranged at the lower part of the base, the transition plate is arranged on the base, the slide rail assemblies are symmetrically arranged on the base, the tube lifting plate is arranged on the slide rail assemblies and can move along the slide rail assemblies to extract the vacuum test tubes in the tube storage bin. The baffle plate is movably arranged on the base and abuts against the connecting rod swing arm. When the connecting rod swing arm rises, it abuts against the baffle plate and pushes the baffle plate upward to intercept the test tubes. When the connecting rod swing arm descends, it disconnects from the baffle plate and the baffle plate will naturally descend to release the test tubes extracted onto the transition plate one by one into the chute mechanism. One end of the connecting rod swing arm is connected to the lifting motor, and the other end is connected to the tube lifting plate. The lifting motor drives the connecting rod swing arm to drive the tube lifting plate to move up and down.

[0008] Preferably, there are at least two tube lifting plates, and the heights of the tube lifting plates are distributed in a stepped manner. The tops of the tube lifting plates close to the transition plate and the top of the transition plate are both inclined surfaces.

[0009] Preferably, the chute mechanism includes a chute bin and an inclined chute plate. The chute bin is arranged on the base, and the inclined chute plate is arranged in the chute bin. The width of the slot on the inclined chute plate is greater than the body diameter of the vacuum test tube and less than the diameter of the test tube cap.

[0010] Preferably, the interception mechanism includes a fixing plate, an electromagnet, and a sub - tube gate. The fixing plate is arranged on the chute bin, the electromagnet is arranged on the fixing plate, and the sub - tube gate is connected to the electromagnet and can move along with the electromagnet to perform multi - level interception, caching or releasing of the vacuum test tubes on the inclined chute plate.

[0011] Preferably, there are at least two gate pieces arranged on the sub - tube gate. The gate pieces are staggered on both sides of the sub - tube gate. Driven by the electromagnet, the sub - tube gate can intercept and cache the vacuum test tubes on the inclined chute plate or release them one by one into the launch pipeline.

[0012] Preferably, the launch pipeline is provided with a drop port and a pressure port. The drop port corresponds to the lower end of the inclined chute plate and is used to drop the vacuum test tubes in the inclined chute plate into the launch pipeline. The pressure port is arranged at the lower part of the launch pipeline and is used to correspond to the pressure tube mechanism.

[0013] Preferably, the tube pressing mechanism includes a mounting plate, a lead screw motor, a lead screw base, a tube pressing motor, a tube pressing shaft, and an intercepting component. The mounting plate is arranged at the lower part of the launching pipe. The lead screw base and the lead screw motor are arranged side by side on the mounting plate, and the output end of the lead screw motor passes through the lead screw base. The tube pressing shaft is arranged at the output end of the lead screw motor and can be driven by the lead screw motor to move to the tube pressing port to compact and fit the label of the vacuum test tube. The tube pressing motor is arranged on the mounting plate and drives the tube pressing shaft to rotate through a belt. The intercepting component is arranged on the mounting plate and can block the lower port of the launching pipe to stop the vacuum test tube in the launching pipe or open the lower port of the launching pipe to make the vacuum test tube fall into the next process position.

[0014] Preferably, the intercepting component includes a rotating motor and an intercepting piece. The rotating motor is arranged on the mounting plate, and the intercepting piece is arranged at the output end of the rotating motor. By driving the intercepting piece with the rotating motor, the lower port of the launching pipe can be intercepted transversely.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the lifting mechanism, the test tubes in the tube storage bin can be automatically extracted one by one and cached one at the top of the lifting mechanism, and then dropped into the chute mechanism one by one for adjusting the posture and conveying of the test tubes. The structure is simple and ingenious in design, and the manufacturing cost is also relatively low. The chute mechanism and the intercepting mechanism cooperate to intercept and cache the test tubes in the chute mechanism and release them into the launching pipe one by one in a graded manner. During this process, the situation of mutual interference between the test tubes can be avoided, enabling the test tubes to queue up and cache orderly waiting for release without damaging the structure. In addition, after the test tubes enter the launching pipe, the tube pressing mechanism intercepts the test tubes again and strengthens and fits the label information on the tube body of the test tubes, and then releases the test tubes into the launching equipment in the next process for launching.

The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Please refer to Figures 1 to 6 As shown, a cache release device of a vacuum test tube specimen intelligent receipt system includes a base 1. A standby tube bin 2, a lifting mechanism 3, a chute mechanism 4, an interception mechanism 5, a launch pipe 6 and a tube pressing mechanism 7 are arranged on the base 1. The standby tube bin 2 is arranged on one side of the base 1 and is used for placing vacuum test tubes. The lifting mechanism 3 is arranged on the base 1 and extends into the standby tube bin 2 and is used for extracting the vacuum test tubes in the standby tube bin 2. The chute mechanism 4 is arranged on the top of the base 1 and on one side of the lifting mechanism 3 and is used for receiving the vacuum test tubes extracted by the lifting mechanism 3 and conveying and caching the vacuum test tubes. The interception mechanism 5 is arranged on the chute mechanism 4 and is used for intercepting the vacuum test tubes conveyed by the chute mechanism 4 at multiple levels to make the vacuum test tubes slide down one by one. The launch pipe 6 is arranged on the side of the base 1 and corresponds to the chute mechanism 4 and is used for receiving the vacuum test tubes that slide down one by one in the chute mechanism 4. The tube pressing mechanism 7 is arranged at the lower end of the launch pipe 6 and is used for preventing or allowing the vacuum test tubes in the launch pipe 6 to fall and for pressing and fitting the labels on the vacuum test tubes again.

[0026] During specific operations, the vacuum test tubes are placed into the standby tube bin 2, and then the lifting mechanism 3 extracts the vacuum test tubes to the top of the base 1 and releases them one by one into the chute mechanism 4. The vacuum test tubes slide in the chute mechanism 4, and the interception mechanism 5 performs multi-stage interception on the vacuum test tubes in the chute mechanism 4 according to the received system signals, so that they are cached in the chute mechanism 4 and the vacuum test tubes are released into the launch pipe 6 in an orderly manner. The vacuum test tubes in the launch pipe 6 will be stopped by the pipe pressing mechanism 7. Subsequently, the pipe pressing mechanism 7 compacts and fits the labels of the vacuum test tubes in the launch pipe. Finally, according to the system signals, the vacuum test tubes are released and transported along the launch pipe 6 to the next process.

[0027] Please refer to Figure 2 As shown, the lifting mechanism 3 includes a lifting motor 32, a connecting rod swing arm 33, a slide rail assembly 31, a tube lifting plate 34, a baffle 36 and a transition plate 35. The lifting motor 32 is arranged at the lower part of the base 1, the transition plate 35 is arranged on the base 1, the slide rail assembly 31 is symmetrically arranged on the base 1, the tube lifting plate 34 is arranged on the slide rail assembly 31 and can move along the slide rail assembly 31 to extract the vacuum test tubes in the standby tube bin 2. The baffle 36 is movably arranged on the base 1 and abuts against the connecting rod swing arm 33. When the connecting rod swing arm 33 rises, it abuts against the baffle 36 and pushes the baffle 36 to rise to intercept the test tubes. When the connecting rod swing arm 33 descends, it will disconnect the abutting relationship with the baffle 36, and the baffle 36 will naturally descend due to its own gravity, and release the test tubes extracted onto the transition plate 35 one by one into the chute mechanism 4. One end of the connecting rod swing arm 33 is connected to the lifting motor 32, and the other end is connected to the tube lifting plate 34. The lifting motor 32 drives the connecting rod swing arm 33 to drive the tube lifting plate 34 to lift and lower.

[0028] There are at least two tube lifting plates 34, and the heights of the tube lifting plates 34 are distributed in a stepped manner. The tops of the tube lifting plates 34 close to the transition plate 35 and the top of the transition plate 35 are both inclined surfaces.

[0029] During operation, the lifting motor 32 drives the connecting rod swing arm 33 to drive the tube lifting plate 34 to reciprocate up and down to extract the vacuum test tubes in the standby tube bin 2. During the process of extracting the test tubes, the multi-stage tube lifting plates 34 continuously lift the test tubes upward, and the tops of the transition plate 35 and the tube lifting plate 34 are designed with inclined surfaces, which can prevent the test tubes from slipping backward and falling, increasing the success rate of extraction. The baffle 36 at the top of the transition plate 35 can intercept and cache the test tubes, so that the vacuum test tubes are released into the chute mechanism 4 one by one in an orderly manner.

[0030] Please refer to Figure 3As shown, the chute mechanism 4 includes a chute bin 41 and an inclined slot plate 42. The chute bin 41 is arranged on the base 1, and the inclined slot plate 42 is arranged in the chute bin 41. The width of the slot on the inclined slot plate 42 is greater than the diameter of the vacuum tube body and smaller than the diameter of the tube cap. During operation, the vacuum tube body will pass through the inclined slot plate 42 under its own gravity, and the tube cap will be stuck on the inclined slot plate 42 and continue to slide down along the inclined slot plate 42. This process also completes the posture adjustment of the vacuum tube, so that the originally horizontal vacuum tube is adjusted to a vertical position.

[0031] See also Figure 4 As shown, the interception mechanism 5 includes a fixed plate 51, an electromagnet 52 and a branch gate 53. The fixed plate 51 is arranged on the chute bin 41, the electromagnet 52 is arranged on the fixed plate 51, and the branch gate 53 is connected to the electromagnet 52. It can follow the movement of the electromagnet 52 to perform multi-level interception, caching or release of the vacuum test tube on the chute plate 42.

[0032] At least two gates 54 are arranged on the branch gate 53, preferably three, two on one side and one on the other side, and the gates 54 are staggered and arranged on both sides of the branch gate 53. The vacuum tubes on the chute 42 can be intercepted and cached or released one by one into the launch pipe 6 by the drive of the electromagnet 52. During the specific operation, the rear end tube pressing mechanism 7 gives a signal to the electromagnet 52, and the vacuum tubes are intercepted by the branch gate 53. After the electromagnet 52 is powered on, the branch gate 53 moves to the right to open and release the vacuum tubes in the current position (i.e., one end of the two gates 54 is away from the chute bin 41), and also intercepts the vacuum tubes queued behind (i.e., one end of the single gate 54 enters the chute bin 41 for interception). When the electromagnet 52 is powered off, the spring of the electromagnet 52 itself automatically resets, and the vacuum behind moves forward one and is intercepted. In this way, the vacuum tubes slide down into the launch pipe 6 one by one.

[0033] See also Figure 5 As shown, the launch pipe 6 is provided with a drop pipe opening 61 and a pressure pipe opening 62. The drop pipe opening 61 corresponds to the lower end of the chute plate 42 and is used to drop the vacuum test tube in the chute plate 42 into the launch pipe 6. The pressure pipe opening 62 is arranged at the lower part of the launch pipe 6 and is used to correspond to the pressure pipe mechanism 7.

[0034] See also Figure 6As shown in the figure, the tube pressing mechanism 7 includes a mounting plate 71, a lead screw motor 72, a lead screw base 73, a tube pressing motor 74, a tube pressing shaft 75 and an interception assembly 76. The mounting plate 71 is arranged at the lower part of the emission pipeline 6. The lead screw base 73 and the lead screw motor 72 are arranged side by side on the mounting plate 71, and the output end of the lead screw motor 72 passes through the lead screw base 73. The tube pressing shaft 75 is arranged on the output end of the lead screw motor 72 and can drive the tube pressing shaft 75 to move to the tube pressing port 62 through the lead screw motor 72 to compact and fit the label of the vacuum test tube. The tube pressing motor 74 is arranged on the mounting plate 71 and drives the tube pressing shaft 775 to rotate through a belt. The interception assembly 76 is arranged on the mounting plate 71 and can block the lower port of the emission pipeline 6 to stop the vacuum test tube in the emission pipeline 6 or open the lower port of the emission pipeline 6 to make the vacuum test tube fall into the next process position. During specific work, the lead screw motor 72 drives the tube pressing shaft 75 to approach the vacuum test tube, and the tube pressing motor 74 drives the tube pressing shaft 75 to rotate. When the tube pressing shaft 75 abuts against the vacuum test tube, the label information on the vacuum test tube will be compacted and fitted.

[0035] The interception assembly 776 includes a rotating motor 761 and an interception piece 762. The rotating motor 761 is arranged on the mounting plate 71, and the interception piece 762 is arranged on the output end of the rotating motor 761. By driving the interception piece 762 through the rotating motor 761, the lower port of the emission pipeline 6 can be intercepted transversely. Before the vacuum test tube falls from the emission pipeline 6, the rotating motor 761 drives the interception piece 762 to block the lower port of the emission pipeline 6 so that the vacuum test tube can contact the tube pressing shaft 75. When the tube pressing shaft 75 completes the operation on the vacuum test tube, the rotating motor 761 drives the interception piece 762 to release the lower port of the emission pipeline 6 so that the vacuum test tube falls into the emission equipment in the next process for emission.

[0036] Through the lifting mechanism 3 of the present invention, the test tubes in the tube storage bin 2 can be automatically extracted one by one and cached one on the top of the lifting mechanism 3, and then dropped one by one into the chute mechanism 4 for adjustment and transportation of the test tube posture. The chute mechanism 4 cooperates with the interception mechanism 5 to intercept and cache the test tubes in the chute mechanism 4 and release them into the emission pipeline 6 one by one in a graded manner. During this process, the situation of mutual interference between the test tubes can be avoided. In addition, after the test tube enters the emission pipeline 6, the tube pressing mechanism 7 intercepts the test tube again and reinforces and fits the label information on the test tube body, and then releases the test tube into the emission equipment in the next process for emission.

[0037] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
