Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery and equipment, in particular to an injection pen assembly system. Background Art

[0002] An injection pen is a medical device used to inject medication, usually subcutaneously or intramuscularly. Figure 6 and Figure 7 As shown, the injection pen 1 includes a pen cap assembly 101 (pen holder and pen cap), a pen core 102 and a pen metering assembly 103 (mechanical device). At present, the domestic automatic injector market is mainly completed by manual or semi-automatic equipment, with low assembly efficiency and low yield.

[0003] Chinese patent document CN219617121U discloses an injection pen assembly system, in which a first positioning part for placing a mechanical device, a second positioning part for placing a pen holder and a third positioning part for placing a pen cap are provided on a support seat. This system has some disadvantages:

[0004] 1) The system adopts centralized assembly, which requires first placing the components of the injection pen on the positioning parts corresponding to the bearing seat, and then assembling them based on the pen holder. After the pen holder, the mechanical device and the pen core are assembled, the assembled pen holder, the mechanical device and the pen core are installed in the pen cap. There are many assembly steps and the assembly efficiency is low;

[0005] 2) The system uses a single conveyor line to complete a series of process operations such as loading, transportation, assembly and unloading. When a component on the carrier is not loaded or is in an abnormal position, each carrier still needs to go through a complete cycle of the conveyor line before restarting a new round of operations. The utilization rate of each process equipment is low, and the transportation efficiency is low. In addition, when a single conveyor line is operated, the loading and unloading actions and the assembly and transportation actions cannot be completely consistent during the loading and unloading process of each component. Sometimes there will be no load, which will also lead to low equipment utilization rate and low transportation efficiency;

[0006] 3) Although the system is equipped with a finished product inspection device, when a component on the support seat is not loaded or has an abnormal position, the subsequent operation will not stop and the operation will be repeated until the assembly is completed. The finished product inspection device detects that the assembly is unqualified and then removes it, resulting in low yield rate and low efficiency. Utility Model Content

At the same time, the pen cap assembly positioning carrier on the circulating conveying device and the pen cap assembly conveying carrier on the circular conveying line are both loaded based on the pen cap assembly, which is also convenient for the transportation of the two conveying lines. By setting a buffer section, the pen cap assembly is cached in the buffer section, so that when the pen cap assembly is loaded, even if the feeding is interrupted due to reasons such as changing the feeding tray, the empty load rate in the pen cap assembly positioning carrier will not increase, and the system utilization rate is high. The two conveyor lines, the ring conveyor device and the ring conveyor line, are used to discharge the injection pens discharged by the qualified unloading device into the empty pen cap assembly conveying carrier output by the buffer section. The pen cap assembly conveying carrier has high utilization rate, high system utilization rate, and high conveying efficiency. By setting the first empty carrier recovery channel and the second empty carrier recovery channel, the empty pen cap assembly conveying carrier can be returned to the buffer section for the next transfer without going through a complete cycle of the conveyor line.

[0033] like Figures 1 to 5As shown, the injection pen assembly system of this embodiment includes a circulating conveying device 2 and a pen cap assembly feeding device 3, a pen core feeding assembly device 5, a pen core pressing device 6, a pen metering assembly feeding assembly device 8, a pen metering assembly pressing device 9 and a good product unloading device 11 which are arranged in sequence along the circulating conveying device 2. The circulating conveying device 2 is provided with a pen cap assembly positioning carrier 201, and the good product unloading device 11 is connected to a circular conveying line 13. The good product unloading device 11 is used to unload the good injection pen 1 on the circulating conveying device 2 onto the circular conveying line 13. The circular conveying line 13 is provided with a pen cap assembly conveying carrier 202. The circular conveying line 13 extends to form a buffer section 131 between the pen cap assembly feeding device 3 and the circulating conveying device 2. The interior of the circular conveying line 13 is connected with a first empty carrier recovery channel 134 and The second empty carrier recovery channel 135, the pen cap assembly loading device 3 is used to supply the pen cap assembly 101 to the circulating conveying device 2, the buffer section 131 is used to cache the pen cap assembly 101 between the pen cap assembly loading device 3 and the circulating conveying device 2, the pen refill loading and assembly device 5 is used to load and assemble the pen refill 102 into the pen cap assembly 101 on the pen cap assembly positioning carrier 201, the pen refill pressing device 6 is used to press the pen refill 102 into the pen cap assembly 101 on the pen cap assembly positioning carrier 201, the pen metering assembly loading and assembly device 8 is used to load and assemble the pen metering assembly 103 onto the pen cap assembly 101 on the pen cap assembly positioning carrier 201, and the pen metering assembly pressing device 9 is used to press the pen metering assembly 103 onto the pen cap assembly 101 on the pen cap assembly positioning carrier 201 to form the injection pen 1.

[0034] The injection pen assembly system of the present embodiment is assembled based on the pen cap assembly 101. The pen cap assembly positioning carrier 201 is circulated and transported on the circulating conveyor 2, and the pen cap assembly conveying carrier 202 is circulated and transported on the circular conveyor line 13. When assembling the injection pen 1, the pen cap assembly loading device 3 loads the pen cap assembly 101 buffered on the pen cap assembly conveying carrier 202 on the buffer section 131 of the circular conveyor line 13 onto the pen cap assembly positioning carrier 201 on the circulating conveyor 2. On the circulating conveyor 2, the circulating conveyor 2 sequentially transports the pen cap assembly positioning carrier 201 loaded with the pen cap assembly 101 to the pen core loading assembly device 5, the pen core pressing device 6, the pen metering assembly loading assembly device 8, the pen metering assembly pressing device 9 and the good product unloading device 11. The pen core loading assembly device 5 loads and assembles the pen core 102 into the pen cap assembly 101 on the pen cap assembly positioning carrier 201, and the pen core pressing device 6 presses the pen core 102 to the pen cap assembly. In the pen cap assembly 101 on the positioning carrier 201, the pen metering assembly loading and assembly device 8 loads the pen metering assembly 103 and assembles it onto the pen cap assembly 101 on the pen cap assembly positioning carrier 201, the pen metering assembly pressing device 9 presses the pen metering assembly 103 onto the pen cap assembly 101 on the pen cap assembly positioning carrier 201 to form the injection pen 1, and the good product unloading device 11 unloads the assembled injection pen 1 onto the pen cap assembly conveying carrier 202 on the circular conveyor line 13. On the circular conveyor line 13, the empty pen cap assembly conveying carrier 202 passes through the buffer section 131 to cache the pen cap assembly 101. During the caching, the pen cap assembly loading device 3 first loads the pen cap assembly 101 onto the pen cap assembly conveying carrier 202 of the buffer section 131 for caching, and then loads the pen cap assembly 101 on the pen cap assembly conveying carrier 202 onto the pen cap assembly positioning carrier 201 on the circulating conveyor device 2. The empty pen cap assembly conveying carrier 202 continues to be conveyed on the circular conveyor line 13, and the good product unloading device 11 unloads the assembled injection pen 1 onto the empty pen cap assembly conveying carrier 202. Since the good product unloading step rate and the pen cap assembly conveying carrier 202 conveying step rate are not synchronized, and some non-good products cannot be unloaded, a part of the empty pen cap assembly is unloaded. The conveying carrier 202 flows back to the buffer section 131 through the first empty carrier recovery channel 134 for the next transfer, and the other part of the pen cap assembly conveying carrier 202 loaded with the injection pen 1 continues to be conveyed to the next processing device, such as the labeling device 132 (the labeling device 132 is arranged between the feed end of the second empty carrier recovery channel 135 and the feed end of the first empty carrier recovery channel 134), for corresponding processing, and the injection pens 1 that fail the processing are discarded. After being discarded, the empty pen cap assembly conveying carrier 202 flows back to the buffer section 131 through the second empty carrier recovery channel 135 for the next transfer, and the qualified injection pens 1 are discharged again. After being discharged, the empty pen cap assembly conveying carrier 202 flows back to the buffer section 131 through the circular conveyor line 13 for the next transfer.

[0035] The injection pen assembly system of the present embodiment is assembled based on the pen cap assembly 101. The circulating conveying device 2 only needs to assemble the pen core 102 and the pen metering assembly 103 on the pen cap assembly positioning carrier 201 to complete the entire assembly of the injection pen 1. The assembly steps are few and the assembly efficiency is high. At the same time, the pen cap assembly positioning carrier 201 on the circulating conveying device 2 and the pen cap assembly conveying carrier 202 on the circular conveying line 13 are both loaded based on the pen cap assembly 101, which is also convenient for the transportation of the two conveying lines. By setting the buffer section 131, the pen cap assembly 101 is buffered in the buffer section 131, so that when the pen cap assembly 101 is loaded, even if the feeding is interrupted due to reasons such as changing the feeding tray, the empty load rate in the pen cap assembly positioning carrier 201 will not increase, and the system is High mobility; by setting two conveying lines, the circulating conveying device 2 and the annular conveying line 13, the injection pen 1 unloaded by the good unloading device 11 is unloaded into the empty pen cap assembly conveying carrier 202 output by the buffer section 131, and the pen cap assembly conveying carrier 202 has a high utilization rate, a high system utilization rate, and a high conveying efficiency; by setting the first empty carrier recovery channel 134 and the second empty carrier recovery channel 135, the empty pen cap assembly conveying carrier 202 can be returned to the buffer section 131 for the next transfer without going through a complete cycle of the conveying line, and the system utilization rate is high, and the conveying efficiency is high. At the same time, it prevents the empty pen cap assembly conveying carrier 202 from being transported to the labeling device 132 and other processing devices, reduces the empty rate of the processing device transported to the labeling device 132, reduces secondary intervention, and has high efficiency. The injection pen assembly system of this embodiment has the advantages of fewer assembly steps, high system utilization rate, and high efficiency.

[0036] Furthermore, in this embodiment, if Figure 3 As shown, the pen cap assembly positioning carrier 201 is provided with a positioning groove 2011 for positioning the pen cap of the pen cap assembly 101. The positioning groove 2011 matches the shape of the pen cap assembly 101 (the pen cap assembly 101 includes a pen holder and a pen cap that are connected to each other, and the positioning groove 2011 specifically matches the shape of the pen cap of the pen cap assembly 101, wherein the pen cap is also called a pen cover), which is conducive to accurate positioning and stable structure of the pen cap assembly 101 on the pen cap assembly positioning carrier 201 during subsequent assembly.

[0037] Furthermore, in this embodiment, if Figure 2 As shown, the pen metering component loading and assembling device 8 comprises a pen metering component feeding mechanism 81 and a pen metering component loading mechanism 82. The pen metering component loading mechanism 82 is used to load and assemble the pen metering component 103 on the pen metering component feeding mechanism 81 onto the pen cap component 101 on the pen cap component positioning carrier 201. By separating the feeding and loading of the pen metering component 103, it is beneficial to the uninterrupted loading process of the pen metering component 103, thereby improving the device utilization rate.

By setting the pen metering component buffering circulation conveyor line 83 to cache the pen metering component 103, even if the feeding is interrupted due to reasons such as replacement of the feeding tray, the empty load rate in the pen metering component positioning carrier 203 will not increase, thereby improving the device utilization rate.

[0039] Preferably, the pen metering component feeding mechanism 81 includes a pen metering pallet station 811, a pen metering pallet disassembling station 812, a pen metering loading station 813, a pen metering empty pallet stacking station 814 and a pen metering empty pallet recovery station 815, which are arranged in sequence. The whole stack of pen metering component pallets is manually transported or automatically transported by AGV to the pen metering pallet station 811, and then transported to the pen metering pallet disassembling station 812 to disassemble the multi-layer pallets into single-layer pallets. The single-layer pallets are transported to the pen metering loading station 813, and the first transfer mechanism 301 transfers the pen metering component 103 on the pen metering loading station 813 to the pen metering component positioning carrier 203 on the pen metering component buffer circulation conveyor line 83. After the transfer is completed, the empty pallet is transported to the pen metering empty pallet stacking station 814 for empty pallet stacking, and then transported to the pen metering empty pallet recovery station 815 for manual transport or automatic transport by AGV to the empty pallet temporary storage area.

If the pen cap assembly 101 is not carried, the pen refill 102 is not assembled; the pen cap assembly position detection device 7 detects whether the pen cap assembly 101 on the pen cap assembly positioning carrier 201 is accurately positioned, and then assembles the pen metering assembly 103. If the pen cap assembly 101 is not accurately positioned, the pen metering assembly 103 is not assembled, thereby improving the yield rate and assembly efficiency.

[0041] Furthermore, in this embodiment, if Figure 1As shown, the circulating conveying device 2 is provided with a rejecting device 12 between the good product unloading device 11 and the pen cap assembly loading device 3.

The fourth transfer mechanism 304 is used to load the cap assembly 101 on the cap assembly conveying carrier 202 of the buffer section 131 to the cap assembly positioning carrier 201 of the circulating conveying device 2. By providing the buffer section 131 to cache the cap assembly 101, even if the feeding is interrupted due to reasons such as replacement of the feeding tray, the empty load rate in the cap assembly positioning carrier 201 will not increase, thereby improving the device utilization rate.

The single-layer trays are transported to the cap assembly loading station 313, where the third transport mechanism 303 transports the cap assembly 101 on the cap assembly loading station 313 to the cap assembly transport carrier 202 of the buffer section 131. After the transport is completed, the empty tray is transported to the cap assembly empty tray stacking station 314 for empty tray stacking, and then transported to the cap assembly empty tray recovery station 315 to be manually transported or automatically transported by AGV to the empty tray temporary storage area.
