Description

Technical Field

[0001] The present invention relates to the technical field of medical logistics automation, and in particular to a device for specimen turning transmission. Background Art

[0002] In the process of medical / laboratory specimen testing, there is a crucial process - specimen transmission requires turning. The main methods of existing technologies are as follows: Conveyor line turning: This method uses a motor to drive a belt conveyor, and the corresponding conveyor belt is installed according to the required turning direction. Although this method can transport a large number of specimens, the conveyor belt has many sections and the equipment structure is complex. This increases the risk of jamming, the equipment cost is high, and the equipment control is complex.

[0003] Baffle rotation and turning: This method uses a motor to rotate the baffle, which moves the specimen base to the desired position. This method requires controlling the specimen base's conveying speed. The equipment is complex in structure, requires high control requirements, and occupies a large space.

[0004] The specimen base, which carries the specimen, turns due to the friction generated by the tangential rotation of the driving wheel. The method involves placing the specimen on the base, which is tangential to the driving wheel and positioned in all directions on the elbow. As the driving wheel rotates, the tangential specimen base is forced to turn along the elbow due to friction. This equipment is complex, subject to significant wear, slow speed, and a short service life. Summary of the Invention

[0005] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a specimen turning and transmission device with the advantages of simple structure, high efficiency, long service life, and reliable and stable operation. It solves the problems of complex equipment structure, complex equipment control, short service life, and unstable operation in three turning methods: conveyor line conveying turning, baffle rotation and toggle turning, and turning by friction generated by the tangential rotation of the specimen base with the specimen along the driving wheel.

[0006] (2) Technical solution In order to achieve the above-mentioned purpose of simple structure, high efficiency, long service life, and reliable and stable operation, the present invention provides the following technical solutions: a specimen turning transmission device, comprising an elbow, a conveyor belt, a driving wheel, a driving device and a specimen base, wherein the driving device is installed at the bottom of the elbow, a driving wheel is provided on the driving device, a groove is provided on the elbow that is consistent with the track of the elbow, and the interior of the groove is used for the specimen base to pass through, a specimen is placed on the specimen base, an annular conveyor belt is installed inside the elbow that is located at the bottom of the groove and is consistent with the track of the groove, the upper half of the conveyor belt is in contact with the bottom of the specimen base, and the arc section of the lower half of the conveyor belt is fitted on the driving wheel, When the driving wheel is driven to rotate by the driving device, the driving wheel drives the conveyor belt to transmit along its own track, and the upper part of the conveyor belt drives the specimen base in contact with it to move along the elbow track through friction.

[0007] Preferably, a driven wheel is provided at the connection between the vertical section and the horizontal section of the conveyor belt, and the driven wheel is used to limit the bending and position of the conveyor belt.

[0008] Preferably, the bottom of the groove is further provided with a plurality of guide wheels located on both sides of the conveyor belt for limiting the transmission direction of the conveyor belt.

[0015] (3) Beneficial effects Compared with the prior art, the present invention provides a device for specimen turning and transmission, which has the following beneficial effects: This is a device for transporting specimen turns, which is used through the mutual cooperation of a specimen base, a conveyor belt, a driving device, and an elbow. Taking a 90° elbow as an example, the specimen is placed on the specimen base, and the specimen base is transmitted to the inside of the groove of the 90° elbow through an external transmission device. The driving device at the bottom constantly drives the driving wheel to rotate. During the rotation of the driving wheel, the 90° conveyor belt attached to the driving wheel is transmitted along the direction of its own trajectory through friction, so that the entire 90° conveyor belt starts to rotate. During the rotation of the 90° conveyor belt, the contact between the upper half of the 90° conveyor belt and the specimen base drives the specimen base to move along the direction of the elbow through friction, thereby completing a 90° turn of the specimen base. Similarly, a 180° elbow can complete a 180° turn of the specimen base. Thus, the effect of simple structure, high efficiency, long service life, and reliable and stable operation is achieved.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: See also Figure 1-3A device for transporting specimens through a curved path includes an elbow, a conveyor belt, a driving pulley 6, a drive device 5, and a specimen base 1. The drive device 5 is mounted at the bottom of the elbow and is equipped with a driving pulley 6, which provides power for its rotation. The driving pulley 6 rotates under the drive device 5 and is the direct power source for the conveyor belt. It fits tightly against the lower arc section of the conveyor belt, driving the conveyor belt through friction, which in turn drives the specimen base 1.

[0020] The elbow is designed with a groove that aligns with its trajectory. The elbow is a key component of the device, its shape determining the specimen's path and connecting it 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.

[0021] An annular conveyor belt is installed inside the elbow, which is located at the bottom of the groove and has the same groove trajectory. The upper half of the conveyor belt is in contact with the bottom of the specimen base 1. When the driving wheel 6 is driven to rotate by the driving device 5, the driving wheel 6 drives the conveyor belt along its own trajectory. The upper half of the conveyor belt drives the specimen base 1 in contact with it to move along the elbow trajectory through friction.

[0022] A driven pulley 2 is installed at the junction of the vertical and horizontal sections of the conveyor belt to limit its bending and position. The conveyor belt is made of rubber / polyurethane. Because the upper half of the belt is used to drive the specimen base 1 in turns, and the lower half is used to generate the driving force for self-rotation, 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 transmission, making it impossible to maintain the correct transmission path.

[0023] The bottom of the groove is also equipped with several guide wheels 4 on both sides of the conveyor belt to control its transmission direction. As the specimen base 1 is forced to turn around the bend by friction, the direction of the conveyor belt should be consistent with the direction of the bend. Therefore, the guide wheels 4 are required to limit the path of the conveyor belt so that it follows the direction of the bend.

[0024] 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°-180°, and the appropriate angle can be selected according to the actual situation. At the same time, due to the change of the elbow angle, the shape of the conveyor belt also needs to be changed accordingly to adapt to the turning angle of the elbow.

[0025] 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.

[0026] Example 2: See also Figure 4-5 The elbow is a 180° elbow 8, and the conveyor belt is a 180° conveyor belt 9, which can make a 180° turn on the specimen.

[0027] The round belt used for transmission has the advantages of high transmission efficiency, strong adaptability, easy installation, high precision, low noise and good bending performance.

[0028] Working principle: Taking the 90° elbow 7 as an example, the specimen is placed on the specimen base 1, and the specimen base 1 is transmitted to the inside of the groove of the 90° elbow 7 through an external transmission device. The driving device 5 at the bottom constantly drives the active wheel 6 to rotate. During the rotation, the active wheel 6 transmits the 90° conveyor belt 3 attached to the active wheel 6 along the direction of its own trajectory through friction, so that the entire 90° conveyor belt 3 starts to rotate. During the rotation of the 90° conveyor belt 3, the contact between the upper half of the 90° conveyor belt 3 and the specimen base 1 drives the specimen base 1 along the direction of the elbow through friction, thereby completing a 90° turn of the specimen base 1. Similarly, the 180° elbow 8 can complete a 180° turn of the specimen base 1. Thus, the effect of simple structure, high efficiency, long service life, and reliable and stable operation is achieved.
