Description

Technical Field

[0001] The present invention mainly relates to the technical field of sample packaging, and in particular to a fully automatic sample packaging device for an intelligent testing system. Background Art

[0002] Carbon and hydrogen are the main components of coal organic matter, and together with oxygen, they account for more than 95% of coal organic matter; and nitrogen is the only element in coal that exists completely in organic form. Therefore, understanding the carbon, hydrogen and nitrogen content in coal is of great significance for understanding the properties of coal, checking the test results of other indicators, and estimating indicators such as heat, materials, and pollutant emissions during the coal application process.

[0003] The existing methods for detecting carbon, hydrogen and nitrogen elements in coal are based on a variety of detection instruments, but these detection instruments can only automatically complete the detection process after the sample to be tested enters the detection instrument. The weighing of the sample to be tested, the preparation of the sample wrapping tin foil, and the placement of the sample to be tested in the specified position of the detection instrument still require manual operation. Not only is the operation cumbersome and labor-intensive, but there is also the risk of introducing human errors, which brings great difficulties to the company's coal management work. With the development of coal production, processing, utilization and trade at home and abroad, coal has become the main cost of each coal-using unit, and coal quality disputes between supply and demand parties occur from time to time. Therefore, automation, intelligence and de-humanization of the detection link will become a new development direction.

[0004] In the intelligent laboratory project, it is required to compress and exhaust the coal sample carrier of the carbon, hydrogen and nitrogen element analyzer, that is, tinfoil. At present, the tinfoil compression and exhaust production is done by manual operation of the staff. Manual operation may affect the results of the tinfoil compression and exhaust production by human factors, such as mood, finger strength control and glove cleanliness. Moreover, when a large amount of tinfoil compression and exhaust needs to be handled, it is also a job that requires a lot of mental and physical labor for the operator.

[0005] In the intelligent testing system for coal quality analysis, the coal sample carriers used in the automatic testing equipment are calorific value crucibles, ash crucibles, volatile matter crucibles and sulfur crucibles, all of which are rigid hard materials. The transfer and placement of these hard material crucibles can be achieved by a universal transfer mechanism. However, the coal sample carrier used by the carbon, hydrogen and nitrogen element analyzer is tinfoil, which is relatively soft and cannot be transferred and placed by a universal transfer mechanism. At the same time, in the intelligent testing system, tinfoil cannot be weighed using a universal weighing module.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 8 As shown, a fully automatic sample packaging device for an intelligent testing system includes a sample packaging mechanism 1, a clamping and transferring mechanism 2, a clamping jaw 3, and an access mechanism 4. The clamping jaw 3 is arranged on the clamping and transferring mechanism 2 to clamp the sample carrier; the clamping and transferring mechanism 2 drives the clamping jaw 3 to transfer between the access mechanism 4 and the sample packaging mechanism 1; the sample packaging mechanism 1 is used to automatically wrap the sample carrier; the access mechanism 4 is used to place the sample carrier tray and cooperate with the clamping and transferring mechanism 2 to complete the separation of the sample carrier and the sample carrier tray.

[0041] The fully automatic sample packaging device of the present invention is designed with a sample packaging mechanism 1, a clamping and transferring mechanism 2, a clamping claw 3, and an access mechanism 4. When the device is used to package a sample carrier, it is only necessary to use a robot or manually to place the sample carrier holder containing the sample carrier on the access mechanism 4. The clamping and transferring mechanism 2 can automatically and reliably drive the clamping claw 3 to transfer the sample carrier from the access mechanism 4 to the sample packaging mechanism 1. The sample packaging mechanism 1 can automatically sense whether the sample carrier is placed and automatically wrap the sample carrier. By using the device, the sample carrier can be reliably transferred, the sample carrier can be automatically wrapped and the sample is not easy to overflow. The whole device has a simple structure and high working efficiency, and can meet the needs of automatic sample packaging of the intelligent testing system. The sample to be tested after being wrapped can automatically fall into the carbon, hydrogen and nitrogen element analyzer for automatic testing.

[0042] In this embodiment, the clamping and transferring mechanism 2 includes a translation assembly 21 and a lifting device 22. The clamping jaw 3 is connected to the translation assembly 21 through the lifting device 22. The lifting device 22 is used to drive the clamping jaw 3 to perform lifting and lowering movements. The translation assembly 21 is used to drive the clamping jaw 3 to perform horizontal movement. The clamping and transferring mechanism 2 also includes a bracket 23, and the translation assembly 21 is installed on the bracket 23. When in use, the sample carrier with the sample carrier (the sample carrier for the carbon, hydrogen and nitrogen tester is tin foil or tin foil cup) is placed on the access mechanism 4 by a manipulator or manually, and the lifting device 22 moves on the translation assembly 21 to the top of the access mechanism 4, and then the lifting device 22 drives the clamping jaw 3 to perform lifting and lowering movements to take the sample carrier from the access mechanism 4 and transfer it to the sample packaging mechanism 1. The clamping and transferring mechanism 2 can reliably transfer the sample carrier from the access mechanism 4 to the sample packaging mechanism 1, thereby realizing the automatic transfer and placement of the sample carrier.

[0043] In this embodiment, the sample packaging mechanism 1 includes a sample packaging base 11, a clamping assembly 12, a push rod 13, and a driving device 14. The clamping assembly 12 includes more than three triangular clamping blocks 121. The sample packaging base 11 is used to accommodate the clamping assembly 12; one end of the push rod 13 is connected to any one of the triangular clamping blocks 121, and the other end is connected to the driving device 14. The triangular clamping blocks 121 are connected with each other by sliding fit. The driving device 14 is used to drive the push rod 13 to move so as to drive the triangular clamping blocks 121 to move in the opposite direction along the movement direction of the push rod 13, and further drive the triangular clamping blocks 121 to move in a nearly circular shape to achieve tight packaging of the sample carrier.

[0044] When the clamping and transferring mechanism 2 puts the sample carrier (such as tin foil or tin foil cup) into the sample packing mechanism 1, the driving device 14 drives the push rod 13 to move, thereby driving the triangular material clamping block 121 connected to the push rod 13 to move. Since the triangular material clamping blocks 121 are connected by sliding fit, when the triangular material clamping block 121 connected to the push rod 13 moves, the other triangular material clamping blocks 121 move synchronously, and the top angles of the triangular material clamping blocks 121 approach the center of the circle, thus gradually closing in a nearly circular shape to complete the clamping of the sample carrier. The entire mechanism has a simple structure, is easy to operate, and can automatically and efficiently complete the sample packing work of the sample carrier, greatly reducing the labor intensity.

[0045] In this embodiment, the material clamping assembly 12 is composed of 9 triangular material clamping blocks 121 of the same size and specification, and the vertex angle of each triangular material clamping block 121 is 40°. It should be noted that the number of triangular material clamping blocks 121 is not limited to 9, as long as the vertex angles of the multiple triangular material clamping blocks 121 add up to 360°.

[0046] In this embodiment, a cover plate is also included. The cover plate is arranged above the material clamping assembly 12, and a sample placement opening for placing a sample carrier is opened in the center of the cover plate.

[0047] In this embodiment, the push rod 13 includes a first push rod 131 and a second push rod 132 which are arranged in parallel and symmetrically, and the first push rod 131 and the second push rod 132 are respectively connected to the upper top surface and the lower bottom surface of the triangular clamping block 121. The push rod 13 is arranged in parallel and symmetrically, which can ensure that the triangular clamping block 121 is symmetrically stressed from top to bottom, thereby avoiding the jamming phenomenon of multiple triangular clamping blocks 121 moving in the sample packaging base 11.

[0048] In this embodiment, the sample packaging mechanism 1 also includes a boss 15, which is at least arranged on the upper top surface and the lower bottom surface of the triangular clamping block 121 connected to the push rod 13, and the first push rod 131 and the second push rod 132 are connected to the triangular clamping block 121 through the boss 15.

[0049] In the preferred embodiment, the bosses 15 are provided on the upper top and lower bottom of the triangular clamping block 121 connected to the push rod 13, and the upper top and lower bottom of the other two triangular clamping blocks 121 separated by two triangular clamping blocks 121 on both sides of the triangular clamping block 121 are also provided with bosses 15, so as to ensure that the triangular clamping blocks 121 provided with the bosses 15 are evenly arranged and the entire clamping assembly 12 can be balanced in force. The bosses 15 on the upper top and lower bottom of the triangular clamping block 121 are designed as symmetrical structures to ensure uniform force, so that the driving force of the driving device 14 can act evenly on the triangular clamping block 121.

[0050] In this embodiment, the cover plate is provided with through holes whose number matches the number of the bosses 15 and whose structure is coordinated, and the lower bottom surface of the sample packaging base 11 is provided with guide grooves for accommodating the bosses 15, and the number of the guide grooves matches the number of the bosses 15.

[0051] In this embodiment, a triangular material clamping block 121 with a boss 15 is provided every two triangular material clamping blocks 121 among the nine triangular material clamping blocks 121, three matching through holes are provided on the cover plate, and three matching guide grooves are provided on the lower bottom surface of the sample packaging base 11. During installation, the cover plate is first installed on the material clamping assembly 12, the boss 15 passes through the through hole and is connected to the first push rod 131, and then the material clamping assembly 12 is placed in the sample packaging base 11, and the boss 15 on the lower bottom surface of the material clamping assembly 12 passes through the guide groove of the sample packaging base 11 and is connected to the second push rod 132.

[0052] In this embodiment, a first opening and closing mechanism 16 is provided below the sample packaging base 11, and a first sample carrier fixing part 17 and a second sample carrier fixing part 18 are arranged opposite to each other. The first sample carrier fixing part 17 and the second sample carrier fixing part 18 are arranged on the first opening and closing mechanism 16. The first opening and closing mechanism 16 drives the first sample carrier fixing part 17 and the second sample carrier fixing part 18 to move closer to and separate from each other along a straight line. When the clamping claw 3 of the clamping transfer mechanism 2 sends the sample carrier into the sample packaging mechanism, the first sample carrier fixing part 17 and the second sample carrier fixing part 18 move closer to each other under the action of the first opening and closing mechanism 16, and can clamp the sample carrier to prevent the sample carrier from falling; when the sample carrier is wrapped, the first sample carrier fixing part 17 and the second sample carrier fixing part 18 are separated from each other under the action of the first opening and closing mechanism 16, and the wrapped sample falls from the injection channel 19 below the first sample carrier fixing part 17 and the second sample carrier fixing part 18 into the analysis instrument for automatic testing.

[0053] In this embodiment, the storage and retrieval mechanism 4 includes a sample carrier support rack 41, a sample carrier positioning mechanism 42, and a second opening and closing mechanism 43. The sample carrier positioning mechanism 42 is arranged above the sample carrier support rack 41. The sample carrier support rack 41 is provided with a through hole for accommodating the sample carrier support. The sample carrier positioning mechanism 42 includes two relatively arranged positioning jaws 421. The positioning jaws 421 are parallel and symmetrically installed on the second opening and closing mechanism 43. The second opening and closing mechanism 43 drives the relatively arranged positioning jaws 421 to move closer to and apart from each other along a straight line. The second opening and closing mechanism 43 is provided with a second position sensing mechanism 44. The second position sensing mechanism 44 is used to detect the opening and closing distance of the relatively parallel positioning jaws 421. The storage and retrieval mechanism 4 also includes a base 45, and the sample carrier support rack 41 is arranged on the base 45. During specific use, the sample carrier tray containing the sample carrier is placed into the through hole of the sample carrier tray placement rack 41 by a robot or manually, and the two oppositely arranged positioning claws 421 are moved closer to each other under the action of the second opening and closing mechanism 43 to clamp the sample carrier tray and correct the direction of the sample carrier tray.

[0054] In this embodiment, two positioning jaws 421 are symmetrically provided with grooves 4211. When the positioning jaws 421 are brought close to each other, the grooves 4211 clamp and correct the direction of the sample carrier. The specific structure of the grooves 4211 is designed according to the sample carrier and matches the sample carrier.

[0055] In this embodiment, the clamping jaw 3 includes a third opening and closing mechanism 31 and a fourth opening and closing mechanism 32, which are arranged in an up-and-down cross pattern through a fixed bracket 33, and clamping rods 34 are symmetrically provided on the third opening and closing mechanism 31 and the fourth opening and closing mechanism 32, respectively, and a protective cover 341 is provided on the clamping rod 34. In a preferred embodiment, the protective cover 341 is made of a soft material, because the tin foil or tin foil cup used for sample loading in carbon, hydrogen and nitrogen analysis is light in weight and has a smooth surface, and the protective cover 341 made of a soft material can provide sufficient friction, and the tin foil or tin foil cup is not easily misaligned or damaged during the clamping process.

[0056] In this embodiment, the third opening and closing mechanism 31 and the fourth opening and closing mechanism 32 are provided with a first position sensing mechanism 36, which is used to detect the opening and closing distance of the clamping rods 34 arranged opposite to each other, and whether the sample carrier is clamped by mistake can be judged by detecting the opening and closing distance between the clamping rods 34. The clamping jaws 3 are provided with a sample carrier detection device 35, which is used to detect whether the sample carrier is clamped on the clamping jaws 3, thereby improving the reliability of automatic sample transfer.

[0057] The overall operation process of the sample packaging device is as follows:

[0058] Step 1: A robot or a human places the sample carrier tray with the sample carrier on the storage and access mechanism 4;

[0059] Step 2: The sample carrier positioning mechanism 42 on the access mechanism 4 corrects and clamps the sample carrier tray;

[0060] Step 3: The clamping transfer mechanism 2 drives the clamping claw 3 to move to the top of the access mechanism 4, and clamps the sample carrier to separate it from the sample carrier tray;

[0061] Step 4: The clamping and transferring mechanism 2 moves the clamping claw 3 holding the sample carrier to the top of the sample packaging mechanism 1.

[0062] Step 5: The clamping and transferring mechanism 2 extends the clamping claw 3 with the sample carrier into the inlet of the sample packaging mechanism 1, and then the first sample carrier fixing member 17 and the second sample carrier fixing member 18 under the sample packaging base 11 close together to clamp the lower part of the sample carrier, and then the clamping claw 3 is released, and the clamping and transferring mechanism 2 drives the clamping claw to move away. Then the top corner of the triangular clamping block 121 of the clamping assembly 12 of the sample packaging mechanism 1 approaches the center of the circle, and gradually closes in a nearly circular shape to complete the clamping of the sample carrier. At this time, the first sample carrier fixing member 17 and the second sample carrier fixing member 18 are released, and finally the clamping assembly 12 is released, and the wrapped sample falls into the test equipment below (such as a carbon, hydrogen and nitrogen element analyzer) through the injection channel 19.

[0063] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
