Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, and in particular to an automated assembly line for dry powder cartridges. Background Technology

[0002] In industrial production, each step of the dry powder cartridge assembly process is completed manually. This includes: pressing and assembling the dry powder cartridge body and the large filter screen, pressing and assembling the dry powder cartridge cover and the small filter screen, manual filling of sodium bicarbonate powder, ultrasonic welding of the dry powder cartridge body and the dry powder cartridge cover, and the assembly and transfer of various components during production. Existing dry powder cartridge assembly lines mostly rely on manual operation to complete the splicing, fixing, and subsequent testing of various components. For example, in the assembly of the cartridge body and the cover, workers need to manually align the connection points and then weld them using a welding gun to ensure a strong connection. Furthermore, in the dry powder filling step, the filling equipment is operated based on manual experience, making it difficult to accurately control the filling amount. This not only easily leads to material waste but may also affect the product's efficacy due to insufficient filling. Summary of the Invention

[0003] The purpose of this invention is to provide an automated assembly line for dry powder cartridges, which realizes full automation of the dry powder cartridge assembly process. The assembly, fixing and subsequent testing of various parts are completed by machinery, which accurately controls the filling amount of dry powder, reduces material waste, ensures product efficacy, improves product quality, and also greatly reduces labor costs.

[0042] like Figure 2 As shown, in some embodiments of the present invention, the first gripping device 22 is disposed on the top of the first conveyor belt 21. The first gripping device 22 includes a clamping member 221, a clamping cylinder 222, and a flipping mechanism 223. The first conveyor belt 21 conveys the entire group of horizontally stacked dry powder cylinders to the area below the first gripping device 22. The flipping mechanism 223 rotates the entire group of dry powder cylinders to be arranged in a vertical direction. After the clamping cylinder 222 drives the clamping member 221 to clamp the dry powder cylinders, a first translation mechanism 23 is also disposed above the clamping member 221. The first translation mechanism 23 spans across the top of the first turntable 1 to grip and flip a single dry powder cylinder and move it to the first turntable 1. After moving it above the first turntable 1, the clamping member 221 releases to place the dry powder cylinder in the fixed position 11, thereby realizing the full automation of dry powder cylinder feeding.

After the second turntable 41 rotates, it rotates the unfilled dry powder cartridge to below the powder filling position 411, waiting for the powder filling device 43 to fill the dry powder cartridge with powder. After the powder filling is completed, the second turntable 41 rotates again to send the filled dry powder cartridge back below the third gripping device 42, and the third gripping device 42 sends the filled dry powder cartridge back to the first turntable 1. Furthermore, the second turntable 41 is provided with at least two powder filling positions 411, so that the third gripping device 42 can perform feeding or unloading operations while the powder filling device 43 is filling powder, thereby improving the powder filling efficiency.

The lifting cylinder 422 is used to drive the grippers to move up and down to lift the dry powder cylinders. The rotary cylinder 421 is used to exchange the positions of the dry powder cylinders that are not filled with powder and those that are filled with powder on both sides.

[0048] like Figure 5 As shown, in some embodiments of the present invention, the end cap assembly mechanism 5 includes a small filter screen feeding device 51, an end cap feeding device 52, and an end cap assembly device 53. A small filter screen is provided inside the end cap installed on the dry powder cylinder, so the small filter screen needs to be integrated and installed inside the end cap before the end cap is installed. The end cap assembly device 53 includes a third turntable 54, on which the small filter screen feeding device 51 and the end cap feeding device 52 are respectively arranged. A pressing position is opened on the third turntable 54.

The third turntable 54 rotates the end cap to the third pressing mechanism. A third pressing mechanism is arranged above and below the pressing position to press the small filter screen and the end cap together. The pressed end cap is sent to the first turntable 1 by the fourth gripping device 55, realizing the automated assembly of the end cap.

[0049] In some embodiments of the present invention, the fourth gripping device 55 is arranged across the top of the third turntable 54 and the first turntable 1 to transport the end cap containing the small filter screen from the third turntable 54 to the dry powder cylinder of the first turntable 1; the second pressing mechanism includes a second pressing component and a second lifting component. The second pressing component is located above the second turntable 41, and the second lifting component is located below the second turntable 41 and is arranged opposite to the second pressing component. When assembling the end cap and the dry powder cylinder, the end cap is placed on the top of the dry powder cylinder body by the fourth gripping device 55, and then the second pressing component descends while the second lifting component rises, fixing and pressing the end cap and the dry powder cylinder body together in the vertical direction, thereby realizing the automatic assembly of the end cap and the dry powder cylinder body.

[0050] In some embodiments of the present invention, after the end cap and the cylinder are pressed together, the end cap and the cylinder are completely fixed by the welding mechanism 6. The welding mechanism 6 includes a clamping mechanism and a welding machine. The clamping mechanism is located above the first turntable 1. The clamping mechanism includes a clamping fixture and a clamping cylinder 222 that drives the clamping fixture. When the first turntable 1 rotates and sends the dry powder cylinder to the welding machine, the clamping fixture clamps the dry powder cylinder and sends it to a position close to the welding machine. The welding machine is located above the clamping mechanism. After the dry powder cylinder is sent to the bottom of the welding machine, the dry powder cylinder and the end cap are welded together to complete the final welding and fixing of the end cap and the dry powder cylinder.

[0051] like Figure 6 As shown, in some embodiments of the present invention, the sorting device 71 includes a fifth gripping device 73, which is arranged across the first turntable 1, the second conveyor belt 72, and the third conveyor belt 73 via a sorting translation device 74. The inlets of the second conveyor belt and the third conveyor belt 73 are arranged sequentially below the sorting translation device 74. When the fifth gripping device 73 carries the good-quality dry powder cylinders along the sorting translation device 74 to above the second conveyor belt 72, the fifth gripping device 73 places the good-quality dry powder cylinders on the second conveyor belt 72; when the fifth gripping device 73 carries the inferior dry powder cylinders to above the third conveyor belt 73, the fifth gripping device 73 places the good-quality dry powder cylinders on the third conveyor belt 73. Specifically, full-load detectors are also provided on the second conveyor belt 72 and the third conveyor belt 73 to prevent excessive dry powder cylinders from accumulating on the conveyor belts.

[0052] In some embodiments of the present invention, a controller is also included, which may include a PLC or a microcontroller, etc. The controller is electrically connected to the detection device and the sorting device 71. The controller determines good products and bad products based on the detection results of the detection device and sends the determination results to the sorting device 71, so that the fifth gripping device 73 sorts the dry powder cylinders according to the determination results, so that the dry powder cylinders reach the appropriate conveyor belt.

[0053] The working process of this invention is as follows: The cylinder feeding mechanism 2 transports the dry powder cylinder to a position close to the first turntable 1 via the first conveyor belt 21; the first gripping device 22 grips the dry powder cylinder and places it in the fixed position 11; the first turntable 1 rotates to transport the dry powder cylinder to the large filter assembly mechanism 3; the second gripping device 33 grips the large filter to be assembled and places it on top of the dry powder cylinder; then the large filter is pressed into the dry powder cylinder by the first pressing device; the first turntable 1 rotates again to send the dry powder cylinder to the powder filling mechanism 4; the third gripping device 42 grips the dry powder cylinder from the first turntable 1 to the powder filling position 411 of the second turntable 41; the second turntable 41 rotates to send the dry powder cylinder to the powder filling device 43 for filling. After powder filling, the second turntable 41 rotates the dry powder cylinder back to the third gripping device 42, which then returns the filled dry powder cylinder to the first turntable 1. The first turntable 1 rotates to send the filled dry powder cylinder to the end cap assembly mechanism 5. The fourth gripping device places the end cap containing the small filter screen onto the dry powder cylinder, and the second pressing mechanism presses and fixes the end cap to the dry powder cylinder. The first turntable 1 then rotates to send the dry powder cylinder to the welding mechanism 6 for welding. Then, it is inspected by the inspection and unloading mechanism 7. Good products are sent to the second conveyor belt 72 for unloading through the sorting device 71, while inferior products are sent to the third conveyor belt 73 for unloading through the sorting device 71.
