Description

Technical Field

[0001] The present application is used in the technical field of sieve plate filling, and in particular relates to a filling device. Background Art

[0002] The 96-well extraction plate used in the biomass spectrometry industry has deep holes and a large number of holes, while the sieve plates that need to be filled into the 96-well extraction plate are small in size (about 7 mm in diameter and 1.5 mm in thickness), and the price of the sieve plates is relatively high. When the sieve plates need to be placed in each hole of the 96-well extraction plate, the sieve plates are small and the holes on the 96-well extraction plate are also small, so manual installation of each one takes a long time. In addition, tools are used to push the sieve plates into the 96-well extraction plate. Due to the different manual pushing forces, the sieve plates are often damaged or folded, and the sieve plates cannot be evenly distributed in the holes. At the same time, the efficiency of repeated filling of the 96 holes is low, and the actual effects vary greatly in subsequent use. Utility Model Content

[0003] The purpose of the present application is to solve at least one of the technical problems existing in the prior art and to provide a sieve plate filling device which can quickly fill the sieve plate into the hole of the extraction plate.

The sieve plate 500 of the storage tank 300 is convenient to install and can be installed in the storage tank 300 of the storage tank 300.

[0026] See also Figure 2 In some embodiments, the pushing component 100 includes a horizontally arranged pushing plate, and the pushing component 100 is fixedly connected to the end of the support rod 200.

[0027] See also Figure 2, a mounting hole 110 is provided at the bottom of the push component 100, and an internal thread is provided at the end of the support rod 200. The bolt is inserted into the mounting hole 110 from the bottom of the push component 100 and is threadedly connected to the bottom end of the support rod 200. The threaded connection can provide a high connection strength through the bite of the thread, and can withstand a large tensile force or torque; the threaded connection has good anti-loosening performance, and the connecting parts will be tightened due to the force. This allows the connection to remain stable for a long time and is not easy to loosen or fail; the threaded connection can be disassembled and assembled by rotation, without the need for additional tools or special equipment. This makes it convenient and quick to repair, replace parts or make adjustments; the threaded connection can be applied to various materials and shapes, such as metal, plastic, wood, etc. Whether it is coarse thread or fine thread, it can be selected according to needs; the manufacturing cost of the threaded connection is relatively low, and it does not require the use of expensive special tools or equipment.

[0028] See also Figure 2 The top of the pushing component 100 is provided with a socket 120 that matches the bottom end of the support rod 200. The bottom end of the support rod 200 extends into the socket 120 and is connected to the pushing component 100, thereby increasing the stability of the connection between the pushing component 100 and the support rod 200.

[0029] As a preferred embodiment of the present application, a containment member 400 is provided between the tray 300 and the extraction plate 600 to be filled. The containment member 400 is located at the periphery of the plurality of countersunk holes 310 , and the containment member 400 is a frame structure provided along the periphery of the tray 300 .

[0030] In certain embodiments, see Figure 2 The enclosure component 400 is detachably connected to the tray 300, a first boss 330 is provided on the tray 300, and a first fixing groove matched with the first boss 330 is provided on the enclosure component 400, that is, the enclosure component 400 and the tray 300 are installed by positioning the fixed window. The boss and fixed window structure can provide good fixation and support, making the installed object more stable. This structure can prevent the object from moving or shaking under vibration or external force, increasing safety and reliability; the boss and fixed window design can ensure that the installed object is aligned in the correct position to avoid deviation or misalignment. This is very important for parts and equipment that need to be installed precisely, and can ensure their normal operation and functional integrity; the boss and fixed window design makes it easier to remove and replace the installed object, and the installation or maintenance operation can be completed by simply plugging and unplugging the object.

[0031] See also Figure 1, a second boss 610 is provided on the extraction plate 600 to be filled, and a second fixing groove matched with the second boss 610 is provided on the enclosure component 400, and the first fixing groove and the second fixing groove are respectively located on the upper and lower sides of the enclosure component 400, that is, the extraction plate 600 and the enclosure component 400 are connected through the snap-fit ​​feature of the boss and the fixing groove, which makes the operation convenient. The boss and the fixing groove connection has high strength and can withstand large loads and torques. This connection method is usually used for mechanical parts that need to bear heavy loads or vibrations frequently; the boss and the fixing groove connection can provide good positioning performance to ensure that the position of the connected parts is accurate. This is especially important for parts that require precise matching, which can prevent poor assembly and offset problems during operation; the boss and the fixing groove connection is usually easier to disassemble and repair than other forms of connection. The connection can be released by simply lifting or pushing the boss out of the fixing groove, making maintenance and replacement of parts more convenient; since the connection between the boss and the fixing groove is achieved by mutual interlocking, the contact area between them is large, the friction force is evenly distributed, and relative sliding is not easy to occur during operation. Therefore, compared with friction connection, the boss and fixing groove connection is less prone to loss and wear problems.

[0032] As a preferred embodiment of the present application, the through hole 320 on the tray 300 is provided with a chamfer at the opening facing the push component 100, and the chamfer can improve the assembly performance of the parts. During the assembly process, the chamfer can make the alignment of the parts easier, reduce the resistance to insertion and removal, simplify the operation process, and facilitate the insertion of the support rod 200; the chamfer provided at the opening of the through hole 320 on the tray 300 can effectively reduce stress concentration and avoid cracks and fractures caused by stress concentration. When an external load is applied to the opening, the chamfer can disperse the stress to a larger area and reduce the stress peak; it can also prevent the edge of the opening from being easily damaged by wear or collision due to sharp angles, and the chamfer can provide a smooth transition area to reduce the friction and impact when the edge of the opening contacts with other parts; the chamfer can improve the appearance of the tray 300, remove the sharp edge of the opening, make it look smoother and more delicate, and increase the overall texture of the product.

[0033] See also Figure 1 The number of support rods 200 is equal to the number of holes on the extraction plate 600 to be filled. Specifically, the extraction plate 600 to be filled is a 96-hole plate, and the support rods 200 are provided with 96 roots, so that 96 sieve plates 500 can be filled into the holes of the extraction plate 600 at one time.

[0034] In some embodiments, the diameter of the screen plate 500 is 7-7.6 mm, the diameter of the counterbore 310 is 7-8 mm, the diameter of the support rod 200 is 4.5-5 mm, and the length of the support rod 200 is 70-80 mm.

[0035] exist Figure 1 In the state, the tray 300 is installed with the support rod 200 through clearance fit, and the friction between the tray 300 and the support rod 200 is greater than the gravity of the tray 300, and the tray 300 will not fall under the action of gravity. Figure 2 In this state, a certain force is applied to the pushing component 100 to overcome the friction between the tray 300 and the support rod 200, and the support rod 200 is pushed to move the sieve plate 500 into the extraction plate 600.

[0036] The method of using the sieve plate filling device is as follows:

[0037] 1. First, pour the sieve plate 500 into the interior of the enclosure component 400. The tray 300 is provided with a plurality of countersunk holes 310 for placing the sieve plate. After shaking in various directions, the sieve plate 500 will automatically enter each slot in the tray 300. The size of the countersunk holes 310 of the tray 300 can only accommodate one sieve plate 500. Pour the sieve plate 500 into the tray 300 and shake it left and right manually so that the sieve plate 500 gradually enters the 96 countersunk holes. When all the sieve plates 500 enter, remove the enclosure component 400 and scrape off the excess sieve plates 500.

[0038] 2. Remove the enclosure component 400 and clean out the excess screen plate 500;

[0039] 3. Reposition the enclosure component 400 into the tray 300;

[0040] 4. Connect the extraction plate 600 and the enclosure component 400 through the snap-fit ​​feature;

[0041] 5. Press the extraction plate 600 until the top surface of the extraction plate contacts the tray 300. At this time, the sieve plate will first enter the extraction plate. At the same time, push the tray 300 and the support rod 200 into the extraction plate at the same time;

[0042] 6. Then turn over the entire sieve plate filling device, add uniform vertical downward pressure on the pushing component 100, and completely press each sieve plate 500 into the bottom of the extraction plate 600, so that 96 sieve plates 500 are perfectly filled into the holes of the extraction plate 600.
