Description

Technical Field

[0001] This utility model relates to the field of medical logistics automation technology, specifically a transmission mechanism for specimen turning. Background Technology

[0002] In the process of medical / laboratory specimen testing, there is a crucial step – specimen transfer – which requires turning. The main existing technologies for this are as follows:

[0003] Conveyor line turning: This method uses a motor-driven belt conveyor, with the appropriate conveyor belt installed according to the required turning direction. While this method can transport a large number of specimens, it involves many conveyor belt segments, resulting in a complex equipment structure. It also carries a higher risk of jamming, higher equipment costs, and more complex equipment control.

[0004] Baffle rotation and turning: This method uses a motor to rotate a baffle, which moves the specimen base carrying the specimen to the desired position. This method requires controlling the transport speed of the specimen base. The equipment has a complex structure, high control requirements, and occupies a large space.

[0005] The specimen base, carrying the specimen, turns along the friction generated by the tangential rotation of the drive wheel. The method involves placing the specimen on the base, which is tangential to the drive wheel. The base is limited in all directions at the bend, and as the drive wheel rotates, the tangential specimen base turns along the bend due to friction. This method is complex, suffers significant wear, is slow, and has a short service life. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a transmission mechanism for specimen turning, which has the advantages of simple structure, high efficiency, long service life, and reliable and stable operation. It solves the problems of complex structure, complex equipment control, short service life, and unstable operation of three turning methods: conveyor line turning, baffle rotation turning, and turning by friction generated by the tangential rotation of the specimen base along the drive wheel.

[0008] (II) Technical Solution

[0009] To achieve the aforementioned goals of simple structure, high efficiency, long service life, and reliable and stable operation, this utility model provides the following technical solution: A transmission mechanism for specimen turning, comprising an elbow, a transmission belt, a drive wheel, a drive device, and a specimen base. The drive device is installed at the bottom of the elbow, and a drive wheel is provided on the drive device. The elbow has a groove aligned with its trajectory, and the interior of the groove is for the specimen base to pass through. A specimen is placed on the specimen base. An annular transmission belt, located at the bottom of the groove and aligned with its trajectory, is installed inside the elbow. The upper half of the transmission belt contacts the bottom of the specimen base, and the arc segment of the lower half of the transmission belt fits against the drive wheel.

[0010] When the drive wheel is driven to rotate by the drive device, the drive wheel drives the transmission belt to move along its own trajectory. The upper part of the transmission belt drives the specimen base in contact with it to move along the curved trajectory through friction.

[0011] Preferably, a driven wheel is provided at the connection between the vertical and horizontal sections of the conveyor belt, and the driven wheel is used to limit the bending and position of the conveyor belt.

[0012] Preferably, the bottom of the groove is further provided with a plurality of guide wheels located on both sides of the conveyor belt to limit the transmission direction of the conveyor belt.

[0013] Preferably, the conveyor belt is a round belt, and the diameter of the round belt is between 2mm and 5mm.

[0014] Preferably, the bending range of the elbow is 0°-180°.

[0015] Preferably, the elbow is a 90° elbow.

[0016] Preferably, the conveyor belt is a 90° conveyor belt.

[0017] Preferably, the elbow is a 180° elbow.

[0018] Preferably, the conveyor belt is a 180° conveyor belt.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides a transmission mechanism for specimen turning, which has the following beneficial effects:

[0021] This is a transfer mechanism for specimen turning, which utilizes the cooperation of a specimen base, a transfer belt, a drive device, and an elbow. Taking a 90° elbow as an example, the specimen is placed on the specimen base, and the specimen base is transferred to the groove of the 90° elbow by an external transfer device. The drive device at the bottom continuously drives the drive wheel to rotate. During the rotation of the drive wheel, friction propels the 90° transfer belt, which is attached to the drive wheel, along its own trajectory, causing the entire 90° transfer belt to rotate. During the rotation of the 90° transfer belt, the contact point between the upper half of the 90° transfer belt and the specimen base drives the specimen base to move along the direction of the elbow through friction, thus completing the 90° turn of the specimen base. Similarly, a 180° elbow can complete a 180° turn of the specimen base. This achieves the effects of simple structure, high efficiency, long service life, and reliable and stable operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-3A transfer mechanism for specimen turning includes a bend, a conveyor belt, a drive wheel 6, a drive unit 5, and a specimen base 1. The drive unit 5 is mounted at the bottom of the bend, and the drive wheel 6 is mounted on the drive unit 5. The drive unit 5 provides power for the rotation of the drive wheel 6. The drive wheel 6 rotates under the drive of the drive unit 5 and is the direct power source for the movement of the conveyor belt. It is in close contact with the lower arc section of the conveyor belt, and drives the conveyor belt to move through friction, thereby driving the specimen base 1 to move.

[0031] The elbow has a groove that aligns with its trajectory. The elbow is one of the main structural components of the device; its shape determines the specimen's turning path and also connects to the external transport route. The groove on the elbow allows the specimen base 1 to pass through, preventing it from derailing during transport. The specimen base 1 is used to secure the specimen.

[0032] An annular conveyor belt is installed inside the elbow, located at the bottom of the groove and aligned with the groove's trajectory. The upper half of the conveyor belt contacts the bottom of the specimen base 1. When the drive wheel 6 is driven to rotate by the drive device 5, the drive wheel 6 drives the conveyor belt to move along its own trajectory. The upper half of the conveyor belt, through friction, drives the specimen base 1, which is in contact with it, to move along the elbow's trajectory.

[0033] A driven wheel 2 is installed at the connection between the vertical and horizontal sections of the conveyor belt. The driven wheel 2 is used to limit the bending and position of the conveyor belt. The conveyor belt is made of rubber / polyurethane. Since the upper part of the conveyor belt is used to drive the specimen base 1 to turn, and the lower part is used to generate the rotation driving force, the conveyor belt has a vertical connection at one end. This vertical section needs to be limited and tightened. Otherwise, the conveyor belt is prone to disintegration and collapse during the transmission process, thus failing to maintain the correct transmission path.

[0034] The bottom of the groove is also equipped with several guide wheels 4 located on both sides of the conveyor belt to limit the direction of the conveyor belt's transmission. During the process of the specimen base 1 turning along the bend through friction, the direction of the conveyor belt should be consistent with the direction of the bend. Therefore, the guide wheels 4 are needed to restrict the path of the conveyor belt, ensuring it follows the turning direction of the bend.

[0035] The bending range of the elbow is 0°-180°. In this patent, the bending range of the elbow can be set to any angle between 0° and 180°, and a suitable angle can be selected according to the actual situation. At the same time, due to the change in the elbow angle, the shape of the conveyor belt also needs to be changed accordingly to adapt to the turning angle of the elbow.

[0036] In this patent, the elbow is a 90° elbow 7 and the conveyor belt is a 90° conveyor belt 3, which can make a 90° turn on the specimen.

[0037] Example 2:

[0038] Please see Figure 4-5 The elbow is a 180° elbow 8, and the conveyor belt is a 180° conveyor belt 9, which can make 180° turns on the specimen.

[0039] The transmission belt uses round belts, which have advantages such as high transmission efficiency, strong adaptability, simple installation, high precision, low noise, and good bending performance.

[0040] Working Principle: Taking the 90° elbow 7 as an example, the specimen is placed on the specimen base 1. The specimen base 1 is transported to the groove of the 90° elbow 7 via an external transmission device. The drive device 5 at the bottom continuously drives the drive wheel 6 to rotate. During the rotation of the drive wheel 6, friction drives the 90° conveyor belt 3, which is attached to the drive wheel 6, to move along its own trajectory, thus causing the entire 90° conveyor belt 3 to rotate. During the rotation of the 90° conveyor belt 3, the contact point between the upper half of the 90° conveyor belt 3 and the specimen base 1 drives the specimen base 1 to move along the direction of the elbow through friction, thereby completing the 90° turn of the specimen base 1. Similarly, the 180° elbow 8 can complete the 180° turn of the specimen base 1. This achieves the effects of simple structure, high efficiency, long service life, and reliable and stable operation.
