[0039] A finished product unloading and drying device for a liquid medicine filter provided in an embodiment of the present application is now described.

[0040] Example:

[0041] This embodiment provides a finished product unloading and drying device for a liquid medicine filter, based on Figures 1 to 3 As shown, the apparatus comprises a transfer device 1 and a drying device 2. The transfer device 1 comprises a first frame 101 and a transfer mechanism 102 slidably mounted on the first frame 101. A material removal unit 103 is disposed at the bottom of the transfer mechanism 102. The material removal unit 103 removes the assembled liquid medicine filter from the turntable of the filter assembly equipment and transports it through the transfer mechanism 102. The drying device 2 is used to dry the glue that bonds the upper and lower shells of the liquid medicine filter.

[0042] On the basis of the above structure, it also includes a chain conveyor 3, which includes chain jigs 301 arranged in sequence along the conveying direction. One end of the chain conveyor 3 is located at the bottom of the material picking unit 103, and each chain jig 301 is provided with a loading trough 302 corresponding to the material picking unit 103. The transfer mechanism 102 moves back and forth between the turntable and the chain conveyor 3 to transfer the assembled liquid medicine filter from the turntable to the loading trough 302 corresponding to the chain jig 301. The chain jig 301 is transferred through the drying device 2. The chain jig 301 is transferred into the drying device 2, and the drying device 2 dries the liquid medicine filter on the chain jig 301. The dried liquid medicine filter follows the chain jig 301 out of the other end of the drying device 2 for recovery.

[0043] Compared to the transfer device 1, which unloads the liquid medicine filters from the turntable and stacks them before manually transferring them to the drying device 2, the solution of the present application can directly transfer the liquid medicine filters from the turntable to the drying process without manual intervention, thereby improving efficiency. Furthermore, because the liquid medicine filters are directly placed in the corresponding loading trough 302, they are not piled up on each other, which reduces the possibility of liquid medicine filters sticking to each other due to wet glue.

[0044] Preferably, based on Figure 3As shown, any two adjacent loading troughs 302 on each chain jig 301 are arranged in a staggered arrangement. In actual production, to improve space utilization, the gaps between the retrieving units 103 are kept small, resulting in a smaller spacing between adjacent liquid medicine filters on the chain jig 301. Vibration from undried glue during transport can cause adjacent liquid medicine filters to adhere. Therefore, staggering the heights of adjacent loading troughs 302 increases the distance between adjacent liquid medicine filters, reducing the risk of adhesion.

[0045] Preferably, based on Figure 3 As shown, the loading trough 302 is in an oblong shape, so as to leave a margin for the liquid medicine filter when it falls from the material taking unit 103 , thereby preventing the liquid medicine filter from failing to fall into the loading trough 302 due to errors.

[0046] Further, based on Figures 4 to 6 As shown, the chain conveyor 3 further includes a second frame 303, rotating shafts 304 located at both ends of the second frame 303, and sprockets 305 arranged at both ends of each rotating shaft 304. Figure 4 To illustrate the structure of the rotating shafts 304, sprockets 305, and chains 306, a portion of the chain jig 301 is concealed. Chains 306 are mounted on the sprockets 305 at corresponding ends of the two rotating shafts 304. A drive motor 307 is mounted on the second frame 303, which is in transmission connection with either rotating shaft 304. The drive motor 307 can be connected to the rotating shaft 304 using a conventional transmission method, such as a belt drive or a gear drive. Fixed chain plates 308 are mounted on the opposite sidewalls of the two chains 306, extending along the direction of the chains 306. The fixed chain plates 308 can be attached to the chains 306 by welding, bolting, or directly integrated. The fixed chain plates 308 on the two chains 306 are positioned opposite each other, and the ends of the chain jig 301 are connected to the opposite fixed chain plates 308 on the two chains 306 by bolting or welding. The driving motor 307 drives the rotating shaft 304 , the sprocket 305 and the chain 306 to rotate synchronously, thereby driving the chain jig 301 to move.

[0047] Preferably, based on Figure 3 As shown, each fixed chain plate 308 is provided with a protrusion 309 protruding from the top of the chain jig 301. The second frame 303 is equipped with a detection photoelectric switch 310 positioned toward any of the protrusions 309. Each time the chain jig 301 passes a detection photoelectric switch 310, it is blocked by the protrusion 309. After the detection photoelectric switch 310 transmits a signal, it can be compared with the movement of the transfer mechanism 102 to monitor whether there is any deviation in the movement between the chain jig 301 and the transfer device 1. If there is any deviation, the drive motor 307 can be controlled by the PLC controller to synchronize the two.

[0048] Preferably, based on Figure 5 、 Figure 7 and Figure 8 As shown, both sides of the second frame 303 are provided with chutes 311 extending along the direction of the chain 306. The chain 306 extends into the chutes 311 and slides therein. The portion of the chain 306 within the chutes 311 is supported by the bottom wall of the chutes 311. The chutes 311 support the chain 306, preventing the middle portion of the chain 306 from sagging and the chain jig 301 from tilting and causing the liquid medicine filter to slip. To ensure the stability of the chain 306 during transmission, the second frame 303 is equipped with chutes 311 corresponding to both the chain 306 that rotates to the top and the chain 306 that rotates to the bottom, thereby supporting both the top and bottom chains 306. Of course, supporting only the top portion of the chain 306 carrying the liquid medicine filter can also meet transmission requirements.

[0049] Further, based on Figure 5 and Figure 9 As shown, the drying device 2 includes a drying box 201 positioned over the middle of the chain conveyor 3. The walls of the drying box 201 are equipped with heating pipes 202. A power distribution box 203 and a fan 204 connected to the interior of the drying box 201 are located on the top of the drying box 201. The power distribution box 203 controls the heating pipes 202 to heat the interior of the drying box 201. A thermocouple 206 is also located within the drying box 201 to monitor the temperature. The fan 204 increases the fluidity of the gas within the drying box 201 and improves temperature uniformity throughout the drying box 201. The drying box 201 heats the liquid medicine filter to dry the glue that bonds the upper and lower shells.

[0050] Preferably, based on Figure 9 As shown, the side wall of the drying box 201 is provided with an interlayer 205, and the interlayer 205 is filled with heat-insulating materials such as asbestos or glass fiber to reduce heat loss and improve heat utilization.

[0051] Furthermore, buckles 312 are located on both sides of the second frame 303, allowing the drying box 201 to be detachably connected to the second frame 303 via the buckles 312. This arrangement facilitates maintenance and cleaning of the drying box 201 and the continuous plate conveyor. The drying box 201 is shaped like a cover. When installing the drying box 201, it is placed over the center of the continuous plate conveyor and then secured to the second frame 303 using the buckles 312.

[0052] Further, based on Figure 2 、 Figure 5 and Figure 6As shown, a finished product receiving assembly 4 is located at the bottom of the chain conveyor 3, away from the transfer device 1, to receive the dried liquid medicine filters. Specifically, the finished product receiving assembly 4 includes a finished product channel 401, a waste bin 402, and a scraper rod 403 mounted on top of the waste bin 402. The finished product channel 401 is located at the bottom of the chain conveyor 3, away from the transfer device 1. When the chain jig 301 moves to the end of the chain conveyor 3 and flips from upward to downward, the liquid medicine filters on the chain jig 301 fall into the finished product channel 401, where they are collected. Because some of the liquid medicine filters may become stuck to the chain jig 301 due to overflowing glue, preventing them from falling, the scraper rod 403 and waste bin 402 are also provided. The sidewall of the scraper rod 403 faces any chain jig 301 that is conveyed to the bottom, and the scraper rod 403 extends through all the loading troughs 302 on the chain jig 301. When the liquid filter that has not fallen off moves to the scraper rod 403, the scraper rod 403 will scrape the liquid filter off and drop it into the waste box 402. Since the quality of the liquid filter is affected after the glue overflows, the scraped liquid filter will be collected separately in the waste box 402 for subsequent processing.

[0053] Further, based on Figure 1 、 Figure 10 and Figure 11 As shown, the transfer device 1 also includes a reject unloading device. The transfer mechanism 102 is equipped with vertical cylinders 110 corresponding to the retrieving units 103. The retrieving units 103 are connected to the output terminals of the corresponding vertical cylinders 110. All vertical cylinders 110 are signal-connected to the inspection equipment used in the filter assembly process. This can be achieved through automatic control via electrical signals or manual control. The reject unloading device includes a support frame 104, a lift plate 105, and an air blowing device. The support frame 104 can be fixed to the first frame 101. A lift cylinder 106 is mounted on the support frame 104. The lift plate 105 is mounted on top of the support frame 104 and connected to the output terminals of the lift cylinder 106. A lift rod 107 is positioned on top of the lift plate 105, corresponding to the bottom of the filter troughs on the turntable. The air blowing device includes an air outlet pipe 108, with an air outlet terminal 109 corresponding to the top of the filter troughs on the turntable. The air outlet pipe 108 is used to connect to an external air source. The air blown out of the external air source flows along the air outlet pipe 108 and is blown out from the air outlet end 109.

[0054] During use, the liquid medicine filter is assembled on the filter assembly equipment and after the pre-inspection process is completed, the turntable of the filter assembly equipment transfers the liquid medicine filter to the transfer device 1. At the same time, the signal of the pre-inspection process is transmitted to the vertical cylinder 110. First, the vertical cylinder 110 corresponding to the qualified product is actuated, driving the material picking unit 103 to grab the qualified liquid medicine filter. The vertical cylinder 110 corresponding to the unqualified product does not actuate, and the unqualified liquid medicine filter remains on the turntable. Subsequently, the air source blows air, and the gas is blown out from the air outlet 109, blowing the unqualified products into the unqualified product channel 113, and finally falling into the storage box 117 at the bottom. The entire transfer device 1 integrates the separation of unqualified products from qualified products, and there is no need to set up a separate separation process, which simplifies the process and improves production efficiency.

[0055] In this embodiment, the structures of the transfer device 1, the transfer mechanism 102 in the transfer device 1, and the material-taking unit 103 can adopt the corresponding transfer device 1, transfer mechanism 102 and material-taking unit 103 in the Chinese invention patent with application number 202310302119.3, entitled "A Filter Unloading Device", applied for by the same applicant, or the structure of the corresponding components of a medical liquid filter unloading and transferring device disclosed in the Chinese invention patent with publication number CN216004380U (publication date: 2022-03-11) can also be adopted.

[0056] Among them, based on Figure 10 and Figure 11 As shown, the transfer mechanism 102 includes a mounting seat 114, a lifting cylinder 115 and a lifting bracket 116. The lifting cylinder 115 is mounted on the top of the mounting seat 114, and its output end extends to the bottom end of the mounting seat 114. The lifting bracket 116 is connected to the output end of the lifting cylinder 115. The vertical cylinder 110 is arranged on the lifting bracket 116, and the material picking unit 103 is connected to the output end of the vertical cylinder 110. A slide rail 111 and a horizontal transfer cylinder 112 are provided on the top of the first frame 101 of the transfer device 1. The mounting seat 114 is slidably mounted on the slide rail 111, and the output end of the horizontal transfer cylinder 112 is connected to the mounting seat 114.

[0057] When in use, the transfer mechanism 102 is located directly above the turntable. The lifting cylinder 115 drives the lifting bracket 116 to descend, so that all the material picking units 103 are close to the corresponding liquid medicine filters. According to the signal of the pre-inspection process, only the vertical cylinder 110 corresponding to the qualified products is actuated, driving the material picking unit 103 to grab the qualified liquid medicine filters, and the unqualified liquid medicine filters are left on the turntable. After the qualified products are grabbed, the lifting cylinder 115 drives the lifting bracket 116 to rise and lift the qualified liquid medicine filters. Subsequently, the horizontal transfer cylinder 112 drives the transfer mechanism 102 to slide along the slide rail 111, so that the material picking unit 103 moves to the top of the chain mold 301. The lifting bracket 116 is driven down again by the lifting cylinder 115, and the material picking unit 103 is driven to move by the vertical cylinder 110, and the liquid medicine filter is placed in the loading trough 302.

[0058] Further, based on Figure 2 As shown, the bottom of the second frame 303 is provided with a lifting foot 313 and a universal wheel 314. The setting of the universal wheel 314 facilitates the movement of the entire chain conveyor 3. When the position of the chain conveyor 3 is determined, the lifting foot 313 is extended and the universal wheel 314 is suspended in the air to prevent the chain conveyor 3 from moving.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
