The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problems of large amount of operation, complex mechanical structure, low efficiency and low boxing accuracy in boxing of gun tips in the prior art boxing machines, the present application provides an automatic gun tip boxing machine that can quickly and accurately load scattered pipette gun tips into a gun tip box.

[0032] It should be noted that the automatic tip boxing machine in the present application is mainly used to box the tips of pipettes in the biomedical field.

[0033] like Figures 1 to 7The automatic gun tip cartoning machine in this embodiment comprises a frame 10 on which a feeding device 20, a conveying mechanism 30, a material taking and placing device 40, and a platform mechanism 60 for placing a gun tip box 50 are arranged. One end of the conveying mechanism 30 is connected to the feeding device 20, and the other end is provided with a material picking position 70. The conveying mechanism 30 is used to arrange the gun tips output by the feeding device 20 in order and convey them to the material picking position 70; the picking and discharging device 40 is movably arranged on the frame 10, and the picking and discharging device 40 includes a variable-distance picking mechanism 401. When the picking and discharging device 40 moves to the material picking position 70, a plurality of arranged gun tips are obtained through the variable-distance picking mechanism 401, and the gun tips are separated by a fixed distance, so that the distance between two adjacent gun tips is consistent with the distance between two adjacent sockets of the gun tip box 50; and the picking and discharging device 40 moves the gun tip to the discharging position 601, and releases the gun tip so that the gun tip can be positioned and inserted into the socket of the gun tip box 50.

[0034] Specifically, the frame 10 includes a first frame 10110 and a second frame 10210 , wherein the first frame 10110 is used to carry the feeding device 20 , and the second frame 10210 is used to carry the picking and placing device 40 and the platform mechanism 60 , wherein the conveying mechanism 30 is disposed between the first frame 10110 and the second frame 10210 .

[0035] The feeding device 20 includes at least one vibrating disc, and the conveying mechanism 30 includes at least one linear vibrating conveying track. The present invention does not limit the vibrating disc and the linear vibrating conveying track. Figure 4 As shown, the conveying mechanism 30 in this embodiment includes a linear vibrating conveying track, and two conveying channels 301 are arranged on the linear vibrating conveying track. The gun tips output from the feeding device 20 are suspended in the conveying channels 301 in a linear arrangement at a predetermined distance and are transported to the material taking position 70. Correspondingly, the feeding device 20 includes two vibrating discs, that is, the number of vibrating discs is consistent with the number of conveying channels 301 of the linear vibrating conveying track, so that the gun tip products can be output in two straight rows, and the material taking and discharging device 401 can obtain two rows of gun tip products at one time. According to the material taking amount required, the linear vibrating conveying track can be one, two, three, or even more. Similarly, multiple vibrating discs can also be set according to actual needs, as long as the discharge channel of the vibrating disc corresponds to the conveying channel 301 of the linear vibrating conveying track.

[0036] Specifically, the two vibrating discs in this embodiment are both provided with a surrounding annular conveying track (not shown in the figure), which is used to uniformly output the bulk gun heads to the linear vibrating conveying track at a predetermined distance. The starting end of the conveying channel 301 on each linear vibrating conveying track is connected to the discharge port of a vibrating disc, and the end is provided with a material taking position 70.

[0037] In this embodiment, the material picking and unloading device 40 also includes a vertical transmission rail 4021, a second drive mechanism 402, a horizontal transmission rail 404, and a third drive mechanism 403; the variable-distance material picking mechanism 401 is connected to the vertical transmission rail 4021, and the vertical transmission rail 4021 is connected to the second drive mechanism 402. Driven by the second drive mechanism 402, the variable-distance material picking mechanism 401 can perform lifting and lowering movements along the vertical transmission rail 4021; during specific implementation, according to the material picking needs, the variable-distance material picking mechanism 401 can descend along the vertical transmission rail 4021 to the material picking position 70, obtain a number of gun heads arranged on the linear vibrating conveyor rail, and can rise along the vertical transmission rail 4021 to a predetermined position to bring the gun heads away from the linear vibrating conveyor rail. In addition, the horizontal transmission track 404 is connected to the vertical transmission track 4021 and the third driving mechanism 403 respectively. Driven by the third driving mechanism 403, the variable-distance material-picking mechanism 401 and the vertical transmission track 4021 can perform translational movement along the horizontal transmission track 404. Specifically, when the gun tip needs to be boxed after the material-picking and discharging device 40 picks up the material, the variable-distance material-picking mechanism 401 and the vertical transmission track 4021 move translationally along the horizontal transmission track 404. When the translational movement reaches above the material-discharging position 601, the variable-distance material-picking mechanism 401 descends to the material-discharging position 601 along the vertical transmission track 4021, and releases the gun tip under the action of external force so that the gun tip can be positioned and inserted into the jack of the gun tip box 50. With the above structure, the automatic boxing mechanism for gun tips provided by the present invention ensures that the gun tip can accurately enter the jack in the gun tip box 50 without deviating and falling out, thereby improving the efficiency and accuracy of gun tip boxing.

[0038] In this embodiment, preferably, two first sensors 41 for detecting the lifting and lowering into place are provided on the vertical transmission rail 4021 along its rail direction. One of the first sensors 41 is used to detect whether the variable-length material picking mechanism 401 descends to the material picking position 70 or the material discharge position 601 when the variable-length material picking mechanism 401 descends along the vertical transmission rail 4021, and the other first sensor 41 is used to detect whether the variable-length material picking mechanism 401 rises to a predetermined position when the variable-length material picking mechanism 401 rises along the vertical transmission rail 4021, so as to control the start and stop of the second driving mechanism 402 and ensure the accuracy of the control of the movement position of the variable-length material picking mechanism 401. Similarly, the horizontal transmission rail 404 is provided with two second sensors 42 for detecting translation into position along its rail direction. One of the second sensors 42 is used to detect whether the variable-length material picking mechanism 401 and the vertical transmission rail 4021 as a whole translate to above the material discharge position 601 when the variable-length material picking mechanism 401 and the vertical transmission rail 4021 translate along the horizontal transmission rail 404. The other second sensor 42 is used to detect whether the variable-length material picking mechanism 401 and the vertical transmission rail 4021 as a whole translate back to above the material picking position 70 when the variable-length material picking mechanism 401 and the vertical transmission rail 4021 translate along the horizontal transmission rail 404, so as to accurately control the start and stop of the third driving mechanism 403.

[0039] It should be noted that the second drive mechanism 402 and the third drive mechanism 403 can both use a motor and a screw drive connection to provide power drive to the variable distance material taking mechanism 401, or can use a cylinder or other mechanism to provide power drive to the variable distance material taking mechanism 401, which is not limited here.

[0040] Specifically, Figure 3As shown, the variable distance material taking mechanism 401 includes a slide 4011, a plurality of interval blocks 4012 arranged in sequence and arranged on the slide 4011, a first driving mechanism 4014 driving the interval blocks 4012 to be unidirectionally and equidistantly separated, and a suction head structure 4013 arranged on each interval block 4012. The slide 4011 is movably arranged on a vertical transmission track 4021, and the suction head structure 4013 is used to obtain a gun tip located at the material taking position 70. In one embodiment, when the variable distance material taking mechanism 401 is driven by the second driving mechanism 402 to descend to the material taking position 70, the lower end of the suction head structure 4013 extends into the gun tip, and the diameter of the lower end matches the diameter of the gun tip, so that the gun tip can be obtained by a tensioning force; when the gun tip is moved to the material discharge position 601, the gun tip can be released by an external force to be inserted into the jack of the gun tip box 50. Of course, in another preferred embodiment, a negative pressure device can also be used to provide suction power for the suction head structure 4013 to obtain the gun head, which is not limited here. The suction head structure 4013 absorbs the gun head to perform material taking and releasing operations, which is convenient for taking and releasing materials and is not easy to damage the gun head. In addition, multiple suction head structures 4013 can absorb multiple gun heads at the same time, with fast taking and releasing speed and high work efficiency. In addition, it should be noted that the first driving mechanism 4014 can adopt a mechanism such as a cylinder, which is not limited here.

[0041] In this embodiment, Figure 4 As shown, specifically, three slide bars are provided on the slide seat 4011, but are not limited to three slide bars; a plurality of distance blocks 4012 are slidably sleeved on the three slide bars in sequence, wherein the three slide bars are arranged in parallel in a triangle, and such an arrangement is conducive to ensuring the stability and distance accuracy of the distance blocks 4012. Of course, the number of distance blocks 4012 is consistent with the number of jacks in each row of the gun head box 50, and the specific number can be set according to actual needs. Specifically, the number of distance blocks 4012 in this embodiment is twelve, and each distance block 4012 is correspondingly provided with two suction head structures 4013, that is, a total of twenty-four suction head structures 4013, all twenty-four suction head structures 4013 are evenly divided into two rows in sequence for linear arrangement, that is, twelve suction head structures 4013 in each row, so that two rows of gun heads on the material taking position 70 of the two linear vibration conveying tracks can be correspondingly obtained. Driven by the first driving mechanism 4014, the twelve spacing blocks 4012 can be separated linearly at a predetermined distance within the range of the slide bar, so that the distance between two adjacent spacing blocks 4012 is consistent with the distance between two adjacent plug holes of the gun tip box 50. It should be noted that the present invention does not limit the number of spacing blocks 4012 and suction head structures 4013, as long as the number of suction head structures 4013 in each row and the interval after the distance change should match the plug holes in each row on the gun tip box 50.

[0042] In this embodiment, specifically, each distance block 4012 is provided with a pair of limit blocks 80, and each pair of limit blocks 80 is connected between two adjacent distance blocks 4012. Each limit block 80 has a fixed end 81 and a limit end 82, and the limit end 82 is provided with a limit hole 83. The two limit blocks 80 on each distance block 4012 are respectively fixed to the two sides of the distance block 4012 through the fixed end 81, and are slidably connected with the adjacent distance block 4012 through the limit hole 83 on the limit end 82, and so on. That is, in such a configuration, two adjacent distance blocks 4012 are separated and limited at equal distances under the limiting action of the limit blocks 80, so as to ensure that the distances between the multiple distance blocks 4012 when being spaced are kept consistent.

[0043] like Figure 5 and Figure 6 As shown, in this embodiment, the platform mechanism 60 includes a round table 602 and a fourth driving mechanism 603, and the fourth driving mechanism 603 is connected to the round table 602 for driving the round table 602 to rotate. Specifically, the round table 602 is provided with two positions for placing the gun tip box 50. In specific implementation, one of the positions corresponds to the discharge position 601, and the other position is used to place the spare empty gun tip box 50. The two positions can be switched to the position corresponding to the discharge position 601 in turn. When the gun tip box 50 on the position corresponding to the discharge position 601 is fully loaded, the fourth driving mechanism 603 drives the round table 602 to rotate, so that the fully loaded gun tip box 50 exits the discharge position 601, so as to take away the fully loaded gun tip box 50, and the gun tip box 50 on the other position enters the discharge position 601. The fourth driving mechanism 603 can provide rotational power to the round table 602 by connecting the motor to the round table 602, which is not limited here.

[0044] The working principle of the automatic gun tip cartoning machine provided by the present invention is further described below:

[0045] First, the messy gun heads are divided into two rows by two vibrating discs and output to each linear vibration conveying track respectively. The gun heads are arranged in order on each linear vibration conveying track.

[0046] When the linear vibrating conveyor track conveys two rows of gun heads to the end, i.e., the material taking position 70, driven by the second driving mechanism 402, the variable distance material taking mechanism 401 descends to the material taking position 70 along the vertical transmission track 4021, and the lower end of the suction head structure 4013 on the distance block 4012 extends into the gun head, so that two rows of gun heads are obtained, with 12 gun heads in each row, and a total of 24 gun heads;

[0047] After the lower end of the suction head structure 4013 on the distance block 4012 extends into the gun head, the first driving device drives the distance block 4012 to separate and change the distance, so that the distance between two adjacent gun heads is consistent with the distance between two adjacent sockets of the gun head box 50;

[0048] At this time, driven by the second driving mechanism 402, the variable distance material taking mechanism 401 rises along the vertical transmission track 4021 to a predetermined position above the material taking position 70;

[0049] Then, driven by the third driving mechanism 403, the variable-distance material picking mechanism 401 and the vertical transmission rail 4021 are translated to above the material discharge position 601; at this time, driven by the second driving mechanism 402, the variable-distance material picking mechanism 401 moves again along the vertical transmission rail 4021 and descends to the material discharge position 601, accurately releasing the two rows of gun tips and inserting them into the sockets of the gun tip box 50.

[0050] After the above steps are completed, the variable-distance material-retrieving mechanism 401 and the vertical transmission track 4021 are translated back to above the material-retrieving position 70 again, and then the above steps are repeated until the entire gun tip box 50 is filled.

[0051] When the gun tip box 50 on the card position corresponding to the discharge position 601 is full, the fourth driving mechanism drives the round table 602 to rotate, so that the fully loaded gun tip box 50 exits the discharge position 601, so as to take away the fully loaded gun tip box 50 or replace the empty gun tip box 50, and the gun tip box 50 on the other card position enters the discharge position 601, and the cycle is repeated.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0053] 1. Effectively solve the problems of large amount of operation, complex mechanical structure, low efficiency and low accuracy of boxing for gun tips in the boxing machine of the prior art;

[0054] 2. The material taking and discharging device can batch-acquire multiple arranged output gun tip products and put them into the gun tip box, with fast material taking and discharging operation speed and high work efficiency;

[0055] 3. After the material picking and discharging device picks up the material, it can separate and distance multiple arranged output gun tips through the variable distance picking mechanism, so that the distance between two adjacent gun tips is consistent with the distance between two adjacent sockets of the gun tip box, ensuring that the gun tips obtained by the material picking and discharging device are accurately placed in the gun tip box, thereby improving the efficiency and accuracy of gun tip boxing.
