Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnostic equipment, in particular to a novel sample rack transmission device. Background Art

[0002] In vitro diagnostic equipment is generally equipped with a conveying device for transporting sample racks, which are loaded with sample tubes to be tested. There are generally two technical solutions for transporting sample racks. One is to use a small belt conveyor to push the sample rack from the sample inlet area to the conveyor belt. Through the friction between the conveyor belt and the sample rack, the object is transported and then pushed back from the conveyor belt to the sample outlet area. However, it is necessary to accurately align the bottom plates of the sample inlet and sample outlet areas with the conveyor belt, and the processing and assembly accuracy requirements are high. The second is to use a motor to drive the synchronous belt to move, load the sample rack with a carrier, and connect the carrier to the synchronous belt with a connecting arm. However, the travel of the synchronous belt is limited by the connecting arm and cannot achieve a rotation cycle. If the travel is long, a long-distance reset movement is required, which is time-consuming. Therefore, it is necessary to design a sample rack transmission method that solves the above two problems. Utility Model Content

[0003] Aiming at the problems in the two existing technical solutions of high precision requirements for conveyor belt processing and assembly, and long reset time of the synchronous belt driving the carrier to move, the utility model provides a novel sample rack transmission device.

The conveyor belt is provided with a pushing member, which passes through the slit and extends above the transmission plane plate.

[0007] Preferably, it further comprises a bottom plate, a bracket is provided between the transmission plane plate and the bottom plate, and the driving unit is provided on the bottom plate.

[0008] Preferably, the conveyor belt is provided with a plurality of pairs of pushing members that are centrally symmetrical about the geometric center of the conveyor belt.

[0009] Preferably, the distance between each pair of pushing members is greater than or equal to the length of the sample rack.

DETAILED DESCRIPTION

[0017] The following is a more detailed description of the embodiments of the present invention with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the invention after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The utility model provides a novel sample rack transmission device, comprising a transmission plane plate 10, a bottom plate 30 and a driving unit 20 arranged at the bottom of the transmission plane plate 10, which is suitable for in vitro detection equipment such as coagulation analyzers.

[0019] The transport plane 10 is a flat plate that supports the sample rack 40. The sample rack is placed on the upper surface of the transport plane 10 and moves relative to the transport plane 10 under the push of the drive unit 20. Specifically, the transport plane 10 is provided with a linearly extending slit 11. When the sample rack 40 is placed above the slit 11, its two sides are supported by the transport plane 10 on either side of the slit 11. It is then pushed by the pushers 25 extending from the bottom of the slit 11 and moves along the direction of the slit 11. Furthermore, the sample rack 40 is pushed from one side of the slit 11 to the top of the slit 11 by other pusher components of the coagulation analyzer until both sides of the sample rack are supported by the transport plane 10 on either side of the slit 11. The width of the slit 11 needs to be less than or equal to the width of the sample holder 40. The sample rack is prevented from being trapped in the slit 11 and falling or deflecting during the pushing process.

[0020] Please refer to Figure 2 、 4 In the coagulation analyzer, the transmission plane 10 includes a sample inlet area 12, a buffer area 13, and a sample outlet area 14, located on one side of the slit 11. A support area 15 is located on the other side of the slit 11. The buffer area 13 is connected to the sample outlet area 14, and a connection area 16 is provided between the buffer area 13 and the sample inlet area 12. During testing, a sample rack enters the sample inlet area 12, is pushed above the slit 11, and then is pushed along the slit 11 to the vicinity of the sample outlet area 14.

[0021] Please refer to Figure 3 The drive unit 20 includes a driving wheel 21, a driven wheel 22, a conveyor belt 23 connected between the driving wheel 21 and the driven wheel 22, and a drive motor 24 connected to the driving wheel 21. The conveyor belt 23 is generally parallel to the direction of extension of the slit 11 and can be a synchronous belt or a belt. It does not contact the sample rack 40 and is not directly involved in the transmission.

[0022] The conveyor belt 23 is equipped with pushers 25. These pushers 25 extend through the slits 11 and above the conveyor plane 10, making physical contact with the sample racks and thereby pushing them forward. The pushers 25 are compact and do not affect the movement of the conveyor belt 23. Their number can be adjusted based on actual needs. In one embodiment, the conveyor belt 23 is equipped with multiple pairs of pushers 25, symmetrical about the geometric center of the conveyor belt 23, to improve transport efficiency, reduce waiting time, and enable rapid arrival at the target location from any starting position. The spacing between each pair of pushers 25 should be greater than or equal to the length of the sample rack 40, with the sample rack 40 positioned between a pair of pushers 25 to ensure reciprocating movement.

[0023] The bottom plate 30 is located at the bottom of the transmission plane 10 , and the two are connected to each other by a bracket 31 . The driving unit 20 can be mounted on the bottom plate 30 by bolts.

[0024] Compared with the existing technology, the utility model simplifies the structure of the sample rack conveying equipment. The conveyor belt is placed at the bottom of the transmission plane plate and does not contact the sample rack. The components are relatively independent, which greatly reduces the processing and assembly precision requirements, simplifies the assembly process, and facilitates disassembly and maintenance; the conveyor belt and pusher can be rotated and recycled without having to be reset, and multiple pairs of pushers are used to improve the transmission efficiency.

[0025] The above is a description of one or more embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
