Description

Technical Field

[0001] This utility model relates to the field of laboratory medicine technology, and more specifically, to a device for loading containers of biological materials in a delivery system. Background Technology

[0002] As medical laboratories become increasingly automated, the requirements for each link in the automated workflow are constantly rising, especially in large analytical laboratories where enormous workloads occur daily. Manual operation would be extremely stressful. In existing technology, devices for loading biological material containers in a transport system include a tube replenishment device for feeding tubes to a positioning device. This positioning device has a channel with two spaced-apart parallel walls, the distance between which is adjustable, allowing the tube to rotate 90° as it descends horizontally from the replenishment device. The tube is then vertically suspended and positioned on a conveyor belt by a protruding cap relative to its transverse body. The conveyor belt transports the tube to a loading area, where it is moved to the working point by a tube handling device. However, this device uses a single-structure drive for the positioning device. In case of problems, tubes of different diameters can interfere with each other. Furthermore, the device lacks an error zone, making it unable to handle faulty tubes and hindering the normal and orderly operation of the system.

[0003] In summary, how to provide a device that can act as a container for loading biological materials in an automated conveying system, and how to effectively avoid manual intervention, improve operational efficiency, and reduce failure rate, is a problem that urgently needs to be solved by those skilled in the art.

[0073] In summary, the device for loading a biological material container in a conveying system can play a role in loading a biological material container in an automatic conveying system, and the device can effectively avoid manual intervention, improve operation efficiency and reduce failure rate.

[0074] In one embodiment, the hopper comprises a first fixed plate 101, a first support plate 102 arranged on one side of the first fixed plate 101, a second fixed plate 113 arranged opposite to the first fixed plate 101, a second support plate 108 arranged on one side of the second fixed plate 113, and a guide rail assembly 112 arranged between the first fixed plate 101 and the second fixed plate 113; the lifting member comprises a lifting assembly 104, a driving motor 110 connected with the control device, a driving wheel 111 sleeved on the outer circumferential portion of the output shaft of the driving motor 110, a driven wheel 105, and a synchronous belt 107 wound around the outer circumferential portions of the driving wheel 111 and the driven wheel 105, the driving motor 110 is arranged on the second support plate 108, and the lifting assembly 104 is arranged on the synchronous belt 107.

[0075] It should be noted that when the driving motor 110 operates, the driving wheel 111 rotates, thereby driving the driven wheel 105 to rotate, and thereby causing the synchronous belt 107 to rotate, and when the synchronous belt 107 rotates, it can drive the lifting assembly 104 to move up and down, and the end surface of the lifting assembly 104 for lifting the test tube 301 can be arranged as a wavy inclined surface, so that the test tube 301 can be horizontally lifted to a preset position, avoiding the test tube 301 from falling easily during lifting.

The lifting connecting sheet 304 can be arranged at the bottom of the first-stage lifting block 302, the lifting connecting block 303, and the second-stage lifting block 305, and the belt metal piece 307 and the sensor sensing sheet 308 can be installed on one side of the second-stage lifting block 305 through the belt connecting block 306.

[0077] Therefore, when the driving motor 110 operates to drive the synchronous belt 107 to operate, the synchronous belt 107 is connected with the belt metal piece 307, so that when the synchronous belt 107 operates, the lifting assembly 104 can move up and down, and the lifting assembly 104 moves up and down through the sliding cooperation of the sliding block 310 and the guide rail assembly 112. The lifting assembly 104 is mainly used for lifting the test tube 301, and can realize the lifting of test tubes 301 of different specifications (such as blood collection tubes with a diameter of 13 mm*height of 75 mm, a diameter of 13 mm*height of 100 mm, and a diameter of 16 mm*height of 100 mm).

When the test tube 301 is in place, the first in-place sensor 103 is triggered, the control device can control the driving motor 110 to run, so that the synchronous belt 107 operates between the driven wheel 105 and the driving wheel 111, and the lifting assembly 104 can lift the test tube 301 of different specifications from the position of the starting point sensor 106 to the position of the second in-place sensor 109 to complete a lifting action. Moreover, through the cooperation of the guide rail assembly 112, the lifting assembly 104 can complete the up-and-down reciprocating action. During the lifting process of the test tube 301, the test tube 301 is transferred from the last lifting block to the next lifting block through the wave slope surface, and the lifting assembly 104 lifts the test tube 301 once, until the top of the test tube 301 reaches the preset position, and the test tube 301 completes the lifting operation.

[0082] It needs to be added that the turnover mechanism 2 can include a lead screw motor 201, a sensor fixing plate 202, a proximity switch 203, a first compression spring 204, an L-shaped fixing plate 205, a first guide rail mounting plate 206, an induction fixing shaft 207, a second compression spring 208, a T-shaped fixing plate 209, a turnover plate 211 connected to the turnover motor, a second guide rail mounting plate 212, a motor fixing plate 213, a first guide rail 214, a second guide rail 215, a sensor bracket 216, and an origin sensor 210;

[0083] The lead screw motor 201 is mounted on the motor fixing plate 213, one side of the lead screw motor 201 is provided with the sensor fixing plate 202, the sensor fixing plate 202 is used to mount the origin sensor 210, the guide rail surface of the second guide rail 215 is arranged on the inner side of the motor fixing plate 213, the sliding block surface of the second guide rail 215 is arranged on the front surface of the second guide rail mounting plate 212, the lead screw of the lead screw motor 201 is arranged on the upper end surface of the second guide rail mounting plate 212, one side of the second guide rail mounting plate 212 is provided with the sensor bracket 216, the guide rail surface of the first guide rail 214 is arranged on the back surface of the second guide rail mounting plate 212, the sliding block surface of the first guide rail 214 is arranged on the back surface of the first guide rail mounting plate 206, the second guide rail mounting plate 212 and the first guide rail mounting plate 206 are connected through the first compression spring 204, the L-shaped fixing plate 205 is arranged on the end surface of the second guide rail mounting plate 212, the T-shaped fixing plate 209 is arranged on the front surface of the first guide rail mounting plate 206, the proximity switch 203 is arranged on the end surface of the L-shaped fixing plate 205, one end of the induction fixing shaft 207 penetrates through the lower end surface of the L-shaped fixing plate 205, the other end of the induction fixing shaft 207 is sleeved with the induction fixing shaft 207 and is fixed on the lower end surface of the T-shaped fixing plate 209; the origin sensor 210, the proximity switch 203 (i.e. the detection piece) and the lead screw motor 201 are connected with the control device.

[0084] When the test tube 301 reaches the position of the turnover plate 211, the lead screw motor 201 operates to drive the internal lead screw to run downward, the lead screw of the lead screw motor 201 and the second guide rail mounting plate 212 run together, and at the same time, the second guide rail 215 mounted on the second guide rail mounting plate 212 slides downward, as shown in Figure 8 and Figure 9 the initial state of the discrimination mechanism runs downward:

[0085] When the second guide rail mounting plate 212 runs downward, the first guide rail 214 fixed with the second guide rail mounting plate 212 runs synchronously, and drives the L-shaped fixing plate 205, the proximity switch 203, the inductive fixing shaft 207 and the T-shaped fixing plate 209 to slide downward to a specified position, and then a tube diameter judgment action of the test tube 301 is performed. In the running process, the second compression spring 208 and the first compression spring 204 are compressed, and a reaction force is generated, so that the tube diameter judgment action can be reset as soon as possible after being performed once. After the tube diameter judgment action is completed, the overturning motor is controlled to run according to a logical relationship, so that the overturning plate 211 is turned inward or outward.

[0086] The tube diameter judgment method of the test tube 301 is that there are two sizes φ13 and φ16 in the market, the φ13 sample tube diameter range is 12mm-12.8mm, and the detection range is 12mm-13mm; the φ16 sample tube diameter range is 14.5mm-15.6mm, and the detection range is 14.5mm-16mm. Therefore, the proximity switch 203 in this interval is selected for detection, and the detection range of the proximity switch 203 is 0-2.5mm interval, which can be triggered by metal. The inductive fixing shaft 207 is made of metal material, and the distance between the inductive fixing shaft 207 and the proximity switch 203 is 4mm by default.

[0087] When the test tube 301 is in place, the lead screw motor 201 drives downward, and drives the first guide rail 214 and the second guide rail 215 to run downward. At this time, the T-shaped fixing plate 209 runs downward to a specified position. When the T-shaped fixing plate 209 contacts the tube diameter of the test tube 301, the second compression spring 208 is compressed, and the inductive fixing shaft 207 runs upward. At this time, the detection distance of the proximity switch 203 is shortened. When the proximity switch 203 is not triggered, it is determined that the test tube 301 is of the first diameter (for example, the diameter of the test tube 301 is 13mm), and the overturning motor drives the overturning plate 211 to turn inward (i.e. above the first buffer part 4), as shown in Figure 10 When the proximity switch 203 is triggered, it is determined that the test tube 301 is of the second diameter (for example, the diameter of the test tube 301 is 16mm), and the overturning motor drives the overturning plate 211 to turn inward and outward (i.e. above the second buffer part 5), as shown in Figure 11 When the judgment action is completed, the lead screw motor 201 runs upward while driving the sensor bracket 216 to move upward. When the origin sensor 210 is triggered, the lead screw motor 201 stops running.
