Description

Technical Field

[0001] The utility model relates to the technical field of liquid transfer equipment, in particular to an automatic cartoning machine for pipette tips. Background Art

[0002] Automatic boxing of pipette tips is a common and important operation in fields such as laboratories, medicine, and biotechnology. However, existing methods for boxing pipette tips mostly rely on manual operation, which has problems such as low efficiency, high cost, and easy contamination. Specifically, the traditional manual boxing method requires operators to insert the tips one by one into the tip storage box, which is not only time-consuming and labor-intensive, but also easily causes surface contamination of the tips due to human contact, thus reducing product quality.

[0003] Furthermore, while some automated cartoning equipment already exists on the market, these devices often suffer from complex structures, high maintenance costs, and poor adaptability. For example, some devices fail to effectively secure pipette tips, causing them to fall off or shift during the cartoning process; others lack quick-release features, making replacing tips of different specifications cumbersome and time-consuming. To address this, we offer an automated pipette tip cartoning machine. Utility Model Content

[0027] Mounting plate 2: fixed on the three-axis slide 1, with a clamping structure on its surface for stably fixing subsequent components;

[0028] Fixed sleeve 5: connected to the mounting plate 2 via a clamping structure, serving as a carrier for the tip body 6, providing positioning and support during the cartoning process; Tip body 6: sleeved on the lower end of the fixed sleeve 5, is the component actually required for cartoning; Push-off mechanism: connected between the fixed sleeve 5 and the tip body 6, used to automatically remove the tip body 6 at the later stage of cartoning.

[0029] Specifically, the ejection mechanism includes an iron annular ridge 7, which is fixedly connected to the upper end of the nozzle body 6 and serves as a component that interacts with the annular magnet 12; a first connecting block 8, which is fixedly connected to the periphery of the fixed sleeve 5 and has a plug-in rod 9 inserted thereon; the plug-in rod 9, which serves as a connecting component between the first connecting block 8 and the second connecting block 11, is provided with a spring 10 around its periphery to provide the necessary elastic force; the second connecting block 11, which is slidably connected to the periphery of the plug-in rod 9, with an annular magnet 12 fixedly connected between the two second connecting blocks 11. The annular magnet 12 is connected to the periphery of the fixed sleeve 5 and interacts with the iron annular ridge 7 to achieve the fixation and release of the nozzle body 6; and a contact rod 13, which is connected to the lower end surface of the second connecting block 11 and is used to contact the nozzle storage box during the boxing process, thereby triggering the ejection mechanism to cause the nozzle body 6 to fall off.

[0030] like Figure 1-4 As shown, the fixing structure specifically includes: an arc-shaped clamping plate 1 3: fixedly installed on the surface of the mounting plate 2, used for fixing half of the range of the fixed sleeve 5; an arc-shaped clamping plate 2 4: buckled with the arc-shaped clamping plate 1 3, used for fixing the other half of the range of the fixed sleeve 5; a quick disassembly assembly: connected between the arc-shaped clamping plate 1 3 and the arc-shaped clamping plate 2 4, used for realizing quick disassembly and assembly of the two; the fixing structure can firmly fix the fixed sleeve 5 through the cooperation of the arc-shaped clamping plate 1 3 and the arc-shaped clamping plate 2 4, and at the same time, the design of the quick disassembly assembly makes the disassembly and assembly of the fixed sleeve 5 convenient and quick.

[0031] like Figure 1-4As shown, the quick disassembly and assembly component specifically includes: docking block 14: fixedly connected to the periphery of the arc-shaped clamping plate 3; docking block 2 15: fixedly connected to the periphery of the arc-shaped clamping plate 2 4; plug-in block 16: fixedly connected to the surface of docking block 14 opposite to docking block 2 15, and a limited position plug hole 17 is provided from top to bottom; plug-in groove 18 and rectangular groove 19: respectively provided on the side of docking block 2 15; limiting plug rod 20: inserted on docking block 2 15, and passes through the rectangular groove 19, and its periphery is fixedly connected to the limiting ring plate 21; spring 22: sleeved on the periphery of the rectangular groove 19; the quick disassembly and assembly component realizes the quick disassembly and assembly function of the arc-shaped clamping plate 3 and the arc-shaped clamping plate 2 4 through the plug-in cooperation of the plug-in block 16 and the plug-in groove 18, and the limiting cooperation of the limiting plug rod 20 and the limiting plug hole 17.

[0032] The working principle of the present invention is as follows: when the automatic cartoning machine for pipette tips is in operation, the tip body 6 is first moved to the predetermined cartoning position via the three-axis slide 1. During the movement, the tip body 6 is firmly fixed to the fixed sleeve 5 through the interaction between the annular magnet 12 in the push-off mechanism and the iron annular ridge 7. When the abutment rod 13 abuts against the tip storage box, it pushes the connecting block 2 11 upward, causing the annular magnet 12 to move upward and disengage from the iron annular ridge 7. In this way, the tip body 6 will automatically fall off from the fixed sleeve 5 due to the loss of the adsorption force of the annular magnet 12, and be accurately placed in the tip storage box, completing the automatic cartoning process.
