[0037] It should be noted that the filter element assembly machine in the present invention is mainly used for assembling filter elements in pipette tips in the biomedical field.

[0038] like Figure 1The figure is a schematic diagram of the structure of an embodiment of the present invention. The filter element assembly machine in this embodiment includes a frame 10, a feeding device 20, a material dividing device 30, a material receiving device 40 and a material pressing device 50 arranged on the frame 10; wherein the feeding device 20, the material dividing device 30 and the material receiving device 40 are arranged in order from top to bottom on the frame 10, and the material pressing device 50 is arranged in parallel with the material dividing device 30. The feeding device 20 is used to sort the filter elements and transport them to the material dividing device 30 for material dividing. The filter elements after being divided by the material dividing device 30 enter the material receiving device 40. After the material receiving device 40 receives a predetermined number of filter elements, the material receiving device 40 moves to the pressing position. At the pressing position, the gun head box of the filter element to be assembled is located directly below the material pressing device 50, and the filter elements in the material receiving device 40 are assembled into the gun head hole of the gun head box at one time through the material pressing device 50.

[0039] like Figure 2 As shown, the feeding device 20 is provided with a group of discharge ports 201. Specifically, in this embodiment, the number of a group of discharge ports 201 includes 4 but is not limited to 4. The feeding device 20 includes a vibrating disc 200. The 4 discharge ports 201 are arranged on the vibrating disc 200. That is, the feeding device 20 in this embodiment can output 4 filter elements to the dividing device 30 at a time through the vibrating disc 200.

[0040] like Figures 3 to 5 As shown, in this embodiment, specifically, the material distribution device 30 includes a first bracket 300, a material distribution component 310 and a material discharge component 320 arranged on the first bracket 300; the first bracket 300 is fixed to the frame 10, and the material discharge component 320 is arranged below the material distribution component 310. The material discharge component 320 includes two groups of material discharge ports 323, and the number of each group of material discharge ports 323 is the same as that of all the material discharge ports 201; that is, in this embodiment, when the number of material discharge ports 201 is 4, the number of each group of material discharge ports 323 is also 4, and the number of the two groups of material discharge ports 323 is 8. Specifically, the material distribution component 310 is connected to the material discharge port 201 of the feeding device 20 and the material discharge port 323 of the material discharge component 320 respectively. Specifically, the material distribution component 310 includes a material distribution mechanism, which is used to deliver the filter elements output from the material outlet 201 of the feeding device 20 at least twice to all the material outlets 323 of the material discharge component 320 in batches; in this embodiment, the material distribution mechanism is configured to deliver the filter elements output from the material outlet 201 of the feeding device 20 twice to all the material outlets 323 of the material discharge component 320 in batches. That is, in this embodiment, the material distribution mechanism can receive the filter elements (a total of 8 filter elements) output from the material outlet 201 of the feeding device 20 twice and deliver them to the material discharge port 323 in two batches. Since there are 8 material discharge ports 323, the material distribution device 30 distributes 4 filter elements each time, and each 4 filter elements fall into the corresponding 4 material discharge ports 323, wherein the 4 material discharge ports 201 are arranged in a straight line, and the 8 material discharge ports 323 are also arranged in a straight line.

[0041] like Figure 1 , Fig. 9 , Fig.10 , Fig.11 As shown, in this embodiment, the material receiving device 40 is movably located below the material discharge assembly 320 and the material pressing device 50, wherein the material receiving device 40 is provided with a plurality of groups of material receiving holes 4041 for receiving the filter element, and each group of material receiving holes 4041 corresponds to all the material discharge ports 323 of the material discharge assembly 320; all material receiving holes 4041 correspond to all the gun head holes on the gun head box 80. That is, when there are 8 material discharge ports 323, correspondingly, the number of each group of material receiving holes 4041 is also 8, and the 8 material receiving holes 4041 in each group are also arranged in a straight line. In this embodiment, a total of 12 groups of parallel arranged material receiving holes 4041 are provided, that is, a total of 96 material receiving holes 4041. It should be noted that in the present invention, there is no restriction on the number of material receiving holes 4041, which can be set according to actual needs, as long as the number and hole spacing of the material receiving holes 4041 correspond to all the gun heads 90 of the gun head box 80.

[0042] See also Figures 3 to 8 Specifically, the material dividing assembly 310 also includes a lower material dividing plate 312 fixed on the first bracket 300 and an upper material dividing plate 311 arranged above the lower material dividing plate 312; the upper material dividing plate 311 is provided with a plurality of upper material dividing holes 3111 corresponding one-to-one to the discharge port 201 of the feeding device 20, that is, the number of the upper material dividing holes 3111 in this embodiment is also 4, and they are also arranged in a straight line; the lower material dividing plate 312 is provided with a plurality of lower material dividing holes 3120 corresponding one-to-one to the discharge port 323 of the discharge assembly 320, that is, the number of the lower material dividing holes 3120 in this embodiment is 8, and the 8 lower material dividing holes 3120 are evenly divided into two groups of parallel straight line arrangements, and each group has 4 lower material dividing holes 3120. It should be noted that since there is a certain distance between the feeding device and the dividing device, in order to ensure the accuracy of the material dropping, a discharge pipe (not shown in the drawings) is correspondingly connected between each discharge port on the feeding device and each upper dividing hole on the dividing device. After the filter element 70 comes out of the discharge port 201, it accurately falls into the upper dividing hole 3111 through the pipe; similarly, a discharge pipe (not shown in the drawings) is correspondingly connected between each upper dividing hole 3111 on the dividing device 30 and each discharge port 323 on the discharge assembly 320, ensuring that the filter element 70 can be accurately distributed to each discharge port 323.

[0043] Specifically, the material removal assembly 320 includes a connecting plate 321 fixed to the first bracket 300, a material removal plate fixed to the connecting plate 321, and all material removal ports 323 are arranged in a straight line on the material removal plate. Preferably, the material removal plate includes two combined plates 322, each of which is provided with a plurality of semicircular notches, and the plurality of semicircular notches on each combined plate 322 are connected to form the material removal port 323. The use of two combined plates 322 facilitates the installation of the material removal pipe, and the two combined plates 322 are used to clamp and fix the end of the material removal pipe.

[0044] Specifically, the material distribution mechanism includes a transfer plate 313 slidably disposed between the upper material distribution plate 311 and the lower material distribution plate 312, and a first driving device 314 drivingly connected to the transfer plate 313; the first driving device 314 can be fixed on the lower material distribution plate 312, wherein the first driving device 314 is a prior art, and in this embodiment, a cylinder can be used to provide a driving force for the movement of the transfer plate 313, which is not limited here. Specifically, the transfer plate 313 is provided with transfer holes 3130 that are consistent with the number of the lower material distribution holes 3120, that is, when the lower material distribution holes 3120 are 8, correspondingly, the transfer holes 3130 on the transfer plate 313 are also 8. Among them, the transfer holes 3130 can be staggered or overlapped with the upper material distribution holes 3111 and the lower material distribution holes 3120, respectively. Specifically, the 8 transfer holes 3130 are evenly divided into two groups and arranged in a straight line, and each group has 4 transfer holes 3130.

[0045] See Figures 6 to 8 , the transfer plate 313 has a first position and a second position relative to the lower material distribution plate 312. In the first position, the first group of transfer holes 3131 overlap with the upper material distribution holes 3111, and are staggered with the first group of lower material distribution holes 3121, while the second group of transfer holes 3132 overlap with the second group of lower material distribution holes 3122; when in the second position, the second group of transfer holes 3132 overlap with the upper material distribution holes 3111, and are staggered with the second group of lower material distribution holes 3122, and the first group of transfer holes 3131 overlap with the first group of lower material distribution holes 3121. With such an arrangement, relative to the initial state of operation, such as Figure 6 As shown, the transfer plate 313 is located at the first position, the feeding device 20 starts feeding, and the four filter elements 70 sequentially pass through the discharge port 201, the upper distribution holes 3111 of the upper distribution plate 311 and fall into the first group of transfer holes 3131; Figure 7As shown, when the transfer plate 313 moves to the second position, since the first group of transfer holes 3131 and the first group of lower material distribution holes 3121 are arranged in a coincident manner, the filter element 70 in the first group of transfer holes 3131 can pass through the first group of lower material distribution holes 3121 and fall into the corresponding material discharge port 323 in the material discharge assembly 320, that is, one material distribution is completed; when in the second position, since the second group of transfer holes 3132 and the upper material distribution holes 3111 are arranged in a coincident manner, the feeding device 20 provides 4 filter elements 70 again, and the 4 filter elements 70 pass through the discharge port 201 and the upper material distribution holes 3111 of the upper material distribution plate 311 in turn and fall into the second group of transfer holes 3132; as shown Figure 8 As shown, when the transfer plate 313 returns from the second position to the first position, since the second group of transfer holes 3132 and the second group of lower material distribution holes 3122 are arranged to overlap, the filter element 70 in the second group of transfer holes 3132 can pass through the second group of lower material distribution holes 3122 and fall into the corresponding material discharge port 323 in the material discharge assembly 320. Through the above arrangement, the transfer plate 313 moves back and forth once driven by the first driving device 314, that is, it can complete two material distributions, that is, after every two material distributions, 8 filter elements can be distributed to each group of material receiving holes 4041 of the material receiving device 40 through the material discharge port 323. After receiving 8 filter elements, the material receiving device 40 can automatically move so that the next group of material receiving holes 4041 can correspond to the material discharge port 323 to receive the next batch of filter elements 70.

[0046] Specific as Figure 10-11As shown, the material receiving device 40 in this embodiment includes a first slide rail 402 fixed on the frame 10, a second bracket 400 that can horizontally move the first slide rail 402, a second driving device 401 that is drivingly connected to the second bracket 400, and a material receiving assembly arranged on the second bracket 400. The second driving device 401 is a prior art, and in this embodiment, a motor and a screw rod are used to provide a driving force to the second bracket 400, which is not limited here. Specifically, the material receiving assembly includes a material passing plate 403 and a material receiving plate 404 arranged below the material passing plate 403, a plurality of groups of material receiving holes 4041 are arranged in parallel on the material receiving plate 404 in sequence, the material passing plate 403 is provided with a plurality of groups of material passing holes 4031 corresponding to the plurality of groups of material receiving holes 4041, and all the material passing holes 4031 on the material passing plate 403 correspond to all the material receiving holes 4041 on the material receiving plate 404. In addition, each group of feed holes 4031 corresponds to all the feed ports 323 of the feed assembly 320. The function of the feed plate 403 is to ensure the accuracy of the filter element falling into the receiving hole 4041 of the receiving plate 404. In this embodiment, the feed holes 4031 and the receiving holes 4041 each have 12 groups, with 8 holes in each group. In specific implementation, in order to allow the filter element to pass through the feed holes 4031 smoothly, the size of the feed holes 4031 should be slightly larger than the size of the filter element; in order to achieve the bearing effect on the filter element, the size of the receiving hole 4041 should be slightly smaller than the size of the filter element. In the material receiving step, the material receiving device 40 is located below the material distributing device 30, and a group of feed holes 4031 and a group of receiving holes 4041 are aligned with the feed port 323 correspondingly, and the filter elements passing through the feed port 323 pass through the corresponding feed holes 4031 one by one and enter the corresponding receiving holes 404. When one group of receiving holes 4041 is fully connected with 8 filter elements, driven by the second driving device 401, the second bracket 400 drives the receiving assembly to move to the next position, so that the next group of material passing holes 4031 and the next group of receiving holes 4041 are aligned with the discharge port 323, and so on. After all 12 groups of receiving holes 4041 are connected with filter elements, the second driving device 401 drives the second bracket 400 and the receiving assembly on the second bracket 400 to move to the pressing position 505 (i.e., directly below the pressing device), so that the receiving assembly is directly opposite the pressing device 50.

[0047] like Figure 12 to Figure 14As shown, the material pressing device 50 in this embodiment includes a third bracket 500 fixedly arranged on the frame 10, a third driving device 501 arranged on the third bracket 500, and a material pressing part drivingly connected to the third driving device 501, and the material pressing part can move vertically relative to the third bracket 500 under the drive of the third driving device 501. Specifically, the material pressing part includes a seat body 502 drivingly connected to the third driving device 501, a guide rod 504 arranged on the seat body 502, and a plurality of punches 503, the guide rod 504 can vertically slide through the third bracket 500, and the punches 503 correspond to the material receiving hole 4041 and the gun head 90 of the gun head box 80 respectively; specifically, there are 4 guide rods 504, which function to ensure the stability of the seat body 502 in the vertical direction. In this embodiment, there are 96 punches 503. In the material pressing step, driven by the third driving device 501, the seat body 502 and the punch needle 503 move downward, wherein each punch needle 503 correspondingly passes through each material passing hole 4031 on the material passing plate 403 and each material receiving hole 4041 on the material receiving plate 404, so as to respectively load 96 filter elements 70 into the gun head 90 holes on the gun head box 80, that is, the assembly of 96 filter elements is completed at one time, which effectively improves the work efficiency. In this embodiment, the third driving device 501 can adopt a power mechanism such as an electric steel, and the vertical lifting and lowering movement of the material pressing part is controlled by the electric steel with high precision.

[0048] like Fig.10 , or 13 to Fig.14 As shown, specifically, the filter element assembly machine provided by the present invention also includes a gun tip box placement mechanism 60, which includes a second slide rail 602 fixed to the frame 10, a fourth drive device 601, and a rack 600 horizontally movably arranged on the second slide rail 602, the rack 600 is drivingly connected to the fourth drive device 601, and can switch between the box body pick-up and placement position and the pressing position 505 directly below the pressing device 50. Among them, the fourth drive device 601 is a prior art, and in this embodiment, a mechanism such as a cylinder is used to provide power for the horizontal movement of the rack 600, which is not limited here.

[0049] In this embodiment, preferably, along the horizontal moving direction of the rack 600, an in-position sensor 603 is provided on one side of the pressing position 505. Before the pressing action is required, driven by the fourth driving device 601, the rack 600 moves horizontally from the box body pick-up position to the pressing position 505 directly below the pressing device 50 along the second slide rail 602, so that the gun tip box 80 of the rack 600 can be aligned with the pressing part. When the in-position sensor 603 detects that the rack 600 has moved to the position, the rack stops moving. The function of the in-position sensor 603 is to ensure the position accuracy of the gun tip box 80 on the rack 600 moving to the pressing position 505, and to accurately control the start and stop action of the fourth driving device 601. In this embodiment, preferably, a limit block 604 is provided on one side of the box body pick-up position, and the limit block 604 is an L-shaped block. The vertical edge of the L-shaped block is used to limit the rack 600 to prevent it from sliding beyond the second slide rail 602.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] 1.
