Description

Technical Field

[0001] The utility model relates to the technical field of sample collection, and in particular to a sample tube batch conveying device. Background Art

[0002] When various substances such as blood and saliva are tested, they need to be placed in a sample tube, and then placed in a conveying mechanism, and transported to the test sampling location by the conveying mechanism, and the sample liquid in the sample tube is extracted by the sampling device.

[0003] The existing conveying mechanism is generally a conveyor belt, and the sample tubes are conveyed one by one. There is no limiting mechanism in the conveying process. When the sample liquid in the previous sample tube has not been extracted, the next sample tube has been conveyed, which makes it easy for the sample tubes to pile up and get out of order, resulting in poor sampling effect and high error rate. Moreover, after the sample tubes are sampled, they need to be manually taken one by one and placed on a placement plate or a placement rack, which has a low degree of automation and is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a sample tube batch conveying device, which solves the problems of poor stability and reliability and low degree of automation of the existing sample tube conveying mechanism.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A sample tube batch conveying device is provided, which includes a sample plate for placing a plurality of sample tubes and a transverse movement mechanism, the transverse movement mechanism includes a transverse movement conveyor belt transmission connected to a transverse movement motor, a transverse movement seat for limiting the placement of the sample plate is arranged on the transverse movement conveyor belt, the transverse movement seat is slidably matched with a horizontal guide rail, a push platform and a push-out platform are respectively arranged on one side of the front and rear ends of the transverse movement conveyor belt, a push plate for pushing the sample plate into the transverse movement seat is movably arranged on the end of the push platform away from the transverse movement conveyor belt, and a push-out plate for pushing the sample plate from the transverse movement seat is movably arranged on the end of the push platform close to the transverse movement conveyor belt.

[0007] Furthermore, two mutually parallel avoidance grooves are arranged on the propulsion platform, a first connecting member is arranged at the bottom of the propulsion platform, vertical plates are arranged on both sides of the first connecting member, the two vertical plates respectively pass through the two avoidance grooves and are connected to the two sides of the propulsion plate, the two sides of the bottom of the first connecting member are respectively slidably matched with two parallel first slide rails, the first connecting member is fixedly connected to the propulsion conveyor belt, and the propulsion conveyor belt is transmission connected to the propulsion motor.

[0008] Furthermore, guide pillars are arranged on the vertical plate, the push plate is slidably sleeved on the two guide pillars at the same time, and a reset spring is arranged between the push plate and the vertical plate.

[0009] Further, the pushing plate is fixedly connected to the second connecting member. The bottom of the second connecting member is slidably engaged with the second slide rail, and the second connecting member is fixedly connected to the telescopic end of the telescopic cylinder.

[0010] Further, the transverse moving base includes a placing platform. Limit posts are provided at both ends of the placing platform. Smooth inclined surfaces and limit blocks are respectively provided on the front and rear sides of the limit posts. A limit bar is provided at the rear side of the placing platform.

[0011] Further, a number of vertical circular placing grooves are provided on the sample plate, and the number of circular placing grooves are arranged in a line in the horizontal direction.

[0012] Further, a strip-shaped sliding groove is provided at one end of the sample plate, and strip-shaped sliding blocks slidably engaged with the strip-shaped sliding groove are provided on one side of the pushing platform and the pushing-out platform.

[0014] 1. In this solution, a number of sample tubes can be sequentially placed in a number of circular placing grooves on the sample plate, and then the sample plate can be placed on the pushing platform. The sample plate is pushed onto the transverse moving base by the pushing plate. The transverse moving base can drive a number of batches of sample tubes on the sample plate for synchronous transportation, so that the sample tubes will not be stacked or misaligned, facilitating the external collection device to sequentially collect the sample liquid in the sample tubes. At the same time, after the collection is completed, the sample plate can be pushed onto the pushing-out platform by the pushing plate, without the need to individually take and place the sample tubes.

[0015] 2. In this solution, through the sliding cooperation between the strip-shaped sliding block and the strip-shaped sliding groove, the sample plate is effectively prevented from tipping over when being pushed. Through the cooperation of the guide post and the return spring, the elastic connection between the pushing plate and the vertical plate is realized. Compared with the rigid connection, the elastic connection provides a certain error margin for the stroke of the pushing plate and the vertical plate, which is beneficial to the stable pushing of the sample plate.

A pushing plate 7 for pushing the sample plate 1 into the transverse seat 4 is movably provided on the end of the pushing platform 5 away from the transverse conveyor belt 3, and a pushing plate 8 for pushing the sample plate 1 out of the transverse seat 4 is movably provided on the end of the pushing platform 5 close to the transverse conveyor belt 3; a strip slide 26 is provided at one end of the sample plate 1, and a strip slider 27 slidably matched with the strip slide 26 is provided on one side of the pushing platform 5 and the pushing platform 6 to prevent the sample plate 1 from tipping over when being pushed.

[0024] like Figure 3As shown in the figure, two mutually parallel avoidance grooves 9 are provided on the propulsion platform 5. A first connecting member 10 is provided at the bottom of the propulsion platform 5. Vertical plates 11 are provided on both sides of the first connecting member 10. The two vertical plates 11 respectively pass through the two avoidance grooves 9 and are connected to both sides of the propulsion plate 7. The two sides at the bottom of the first connecting member 10 are respectively in sliding fit with two parallel first slide rails 12. The first connecting member 10 is fixedly connected to the propulsion conveyor belt 13. The propulsion conveyor belt 13 is in transmission connection with the propulsion motor 14. In this solution, the reciprocating motion of the propulsion conveyor belt 13 is driven by the propulsion motor 14, so as to realize the stable linear reciprocating motion of the propulsion plate 7.

[0025] As Figure 4 shown in the figure, guide posts 15 are provided on the vertical plates 11. The propulsion plate 7 is simultaneously sleeved on the two guide posts 15 in a sliding manner. The end of the guide post 15 is provided with an abutting block. The abutting block is located in the counterbore of the propulsion plate 7 and abuts against the propulsion plate 7 to prevent the propulsion plate 7 from slipping off the guide post 15. At the same time, the setting of the counterbore prevents the front end of the guide post 15 from protruding from the front end of the propulsion plate 7. A return spring 16 is provided between the propulsion plate 7 and the vertical plate 11. In this solution, through the cooperation of the guide post 15 and the return spring 16, the elastic connection between the propulsion plate 7 and the vertical plate 11 is realized.

[0026] The ejecting plate 8 of this solution is fixedly connected to the second connecting member 17. The bottom of the second connecting member 17 is in sliding fit with the second slide rail 18. The second connecting member 17 is fixedly connected to the telescopic end of the telescopic cylinder 19.

Smooth inclined surfaces 22 and limit blocks 23 are respectively provided on the front and rear sides of the limit posts 21. A limit retaining strip 24 is provided at the rear side of the placement platform 20. The limit block 23 and the limit retaining strip 24 can be used to realize the limit abutment of the sample plate 1.

[0028] In this solution, a number of sample tubes 29 can be sequentially placed in a number of circular placement grooves 25 on the sample plate 1, and then the sample plate 1 is placed on the propulsion platform 5. The sample plate 1 is pushed to the transverse movement base 4 by the propulsion plate 7. The transverse movement base 4 can drive a number of batches of sample tubes 29 on the sample plate 1 to be synchronously conveyed, so that the sample tubes 29 will not be stacked and misaligned, which is convenient for external collection equipment to sequentially collect the sample liquid in the sample tubes 29. At the same time, after the collection is completed, the sample plate 1 can be pushed to the ejection platform 6 by the ejecting plate 8, and there is no need to take and place the sample tubes 29 one by one.
