[0039] This embodiment also includes a pushing mechanism 500 and a vibrating conveying device 600. The vibrating conveying device 600 is located above the pushing mechanism 500. The vibrating conveying device 600 is used to drop the filter 7 in front of the pushing mechanism 500. The pushing mechanism 500 is used to push the filter 7 to the bottom of the tubular container 100.

[0040] Refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 7 , Attachment Figure 8 This embodiment also provides a workflow of a tubular filter assembly device, including the following steps:

[0041] S1: The first plugging material sorting mechanism 2 conveys a group of first pluggings 71 to the conveyor belt 1, and the conveyor belt 1 conveys the first pluggings 71 to the diaphragm assembly station 01; wherein, the specific steps of conveying the first pluggings 71 to the diaphragm assembly station 01 are as follows:

[0042] After the first plugging material sorting mechanism 2 conveys a group of first pluggings 71 to the conveyor belt 1, the baffle 04 is moved to block the discharge port of the first plugging material sorting mechanism 2, and the conveyor belt 1 conveys the first pluggings 71 to the diaphragm assembly station 01; then the baffle 04 leaves the discharge port of the first plugging material sorting mechanism 2, and the next round of conveying the first pluggings 71 begins. In this process, after the first plugging in place detection mechanism 8 detects that there are first pluggings 71 in the conveying trough 11 on the conveyor belt 1, the baffle 04 is moved to block the discharge port of the first plugging material sorting mechanism 2.

[0043] S2: The membrane suction assembly mechanism 3 sucks the membrane 72 cut by the filter membrane cutting machine 6 and assembles it in the first plug 71, transports the first plug 71 equipped with the membrane 72 to the filter assembly station 02, and presses the second plug 73 transported to the filter assembly station 02 down onto the first plug 71 to complete the assembly of the filter 7; wherein, when a group of first plugs 71 are transported to the membrane assembly station 01, the filter membrane cutting machine 6 cuts the membrane 72 on the filter membrane 61, and the membrane suction assembly mechanism 3 simultaneously performs the process of sucking the membrane and pressing the membrane into the first plug 71. The suction nozzle 32 of the membrane suction assembly mechanism 3 sucks the membrane 72 by lifting and rotating to the top of the first plug 71, and then puts the membrane 72 into the first plug 71 by lifting and lifting; in this process, the membrane suction assembly mechanism 3 reduces the distance between the suction nozzles 32 through the variable distance component when sucking the membrane, and expands the distance between the suction nozzles 32 when assembling the first plug 71 and the membrane 72.

[0044] The specific steps for assembling the second plug 73 on the first plug 71 are as follows: the second plug material sorting mechanism 4 transports a group of second plugs 73 to the second cache mechanism 05. After the sensor detects that there are second plugs 73 in the second cache mechanism 05, the second cache mechanism 05 opens the channel connected to the conveyor belt 1 by removing the pad 051 under the second plug 73, and the pressing mechanism 5 presses the second plug 73 down onto the first plug 71 equipped with the diaphragm 72.

[0045] S3: The filter 7 is transported to the filter assembly station 03, the positioning clamping mechanism 300 clamps the tubular container 100, and the filter 7 is moved upward to complete the assembly of the filter 7 and the tubular container 100; after the medicine filling process is completed, the cap is moved downward to complete the assembly of the cap and the tubular container 100.

[0046] Among them, the specific steps of conveying the filter 7 to the filter assembly station 03 are as follows: the horizontal pushing mechanism pushes the filter 7 on the conveyor belt 1 onto the horizontal vibrating conveying device 600, the filter 7 comes to the discharge port of the horizontal vibrating conveying device 600 and then falls onto the pushing mechanism 500 along the falling channel, and the pushing mechanism 500 pushes the filter 7 to the filter assembly station 03.

[0047] The specific steps of assembling the filter 7 and the tubular container 100 are as follows: the filter 7 is transported to the filter assembly station 03, the tubular container 100 moves to the filter assembly station 03, the positioning clamping mechanism 300 clamps the upper and lower ends of the tubular container 100, the positioning plate 400 descends to abut against the top of the tubular container 100, and the lifting and pressing mechanism 200 pushes the filter 7 to move upward, so that the filter 7 is sleeved on the tubular container 100.

[0048] An assembly method of the filter 7: the first plug 71 is a bottom cylinder, the second plug 73 is a cylinder body, and in step S2, the membrane 72 is first installed in the bottom cylinder, and then the cylinder body is pressed down on the bottom cylinder.

[0049] Another assembly method of the filter 7: the first plug 71 is the cylinder body, the second plug 73 is the bottom cylinder, and in step S2, the membrane 72 is first installed in the cylinder body, and then the bottom cylinder is pressed down to cover the cylinder body.

[0050] The specific conveying process on the conveyor belt 1 is as follows: the first conveyor belt conveys the first plug 71 to the diaphragm assembly station 01. After the diaphragm 72 is assembled, the first conveyor belt continues to convey, and the horizontal push mechanism pushes a group of first plugs 71 with diaphragms 72 into the horizontal vibration conveying mechanism; the horizontal vibration conveying mechanism conveys a group of first plugs 71 with diaphragms 72 to the second conveyor belt; the second conveyor belt conveys the first plug 71 with diaphragms 72 to the filter assembly station 02, and after the second plug 73 is assembled, the second conveyor belt conveys it to the filter assembly station 03. In this process, the visual inspection device detects whether the first plug 71 is equipped with a diaphragm 72. The first plug 71 equipped with a diaphragm 72 is pushed into the horizontal vibration conveying mechanism by the horizontal push mechanism, and the first plug 71 without a diaphragm 72 is removed from the first conveyor belt. The horizontal vibration conveying mechanism conveys a set of first plugs 71 equipped with diaphragms 72 to the first buffer mechanism above the second conveyor belt. After the sensor detects that there is the first plug 71 in the first buffer mechanism, the first buffer mechanism opens the channel connected to the second conveyor belt. Then the first plug 71 falls from the first buffer mechanism to the second conveyor belt below.

[0051] Refer to the attached Fig. 9 , a corrugated section 061 is provided on the tubular container 06. The tubular container 06 is similar to a straw, and the tube wall is relatively thin and easily deformed. The corrugated section 061 is easily bent, and it is difficult to directly assemble the diaphragm 72 or the filter of the prior art on it. In the utility model, the diaphragm 72 is first fixed between the bottom cylinder and the cylinder body, avoiding the trouble of fixing the diaphragm 72 on the tubular container 06, and then the cylinder body is sleeved on the tubular container 06 to complete the assembly of the two.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
