Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] The present application will now describe a filter unloading device according to an embodiment.

[0044] Example:

[0045] This embodiment provides a filter unloading device, based on Figure 1 , Figure 3 and Figure 7As shown, the system includes a transfer device 1, a carrying device 2, and a non-conforming product unloading device 3. The carrying device 2 is provided with a conforming product channel 201 and a non-conforming product channel 202. The transfer device 1 is arranged with picking units 101 corresponding one-to-one with the filter slots 200 on the fixture 100. In this embodiment, twenty-four filter slots 200 are linearly arranged on the fixture 100, which can simultaneously load twenty-four filters. Correspondingly, the transfer device 1 is linearly arranged with twenty-four sets of picking units 101. Each picking unit 101 is provided with an independent drive device. All independent drive devices are connected to the detection equipment used in the detection process of the filter assembly equipment via signal connection, which can be achieved through automatic electrical signal control or manual control. The picking unit 101 moves back and forth between the fixture 100 and the conforming product channel 201. The non-conforming product unloading device 3 corresponds to the filter slots 200 on the fixture 100 and is positioned facing the non-conforming product channel 202.

[0046] After the filters are assembled and tested on the filter assembly equipment, the turntable of the filter assembly equipment moves the fixture 100 containing the filters to the filter unloading device. Simultaneously, the signal from the pre-testing process is transmitted to the independent drive devices. During operation, the twenty-four independent drive devices selectively operate based on the signals from the pre-testing process; only the drive device corresponding to the qualified product section operates, driving the picking unit 101 to grab qualified filters. The drive device corresponding to the unqualified product section remains inactive, leaving the unqualified filters on the fixture 100. Once all qualified products are removed, the picking unit 101 moves from the fixture 100 to the qualified product channel 201, and the independent drive devices operate again, causing the filters to detach from the picking unit 101 and fall into the qualified product channel 201. For unqualified products remaining on the fixture 100, the unqualified product unloading device 3 moves them to the unqualified product channel 202. After all filters are unloaded, the picking unit 101 moves back above the fixture 100 to receive the next batch of filters. This filter unloading device integrates the separation of defective and qualified products into the unloading device, eliminating the need for a separate separation process, simplifying the process and improving production efficiency.

[0047] Furthermore, based on Figures 1 to 4As shown, the transfer device 1 includes a first frame 102 and a transfer mechanism 103. The first frame 102 is a vertically placed rectangular frame structure, and a transverse transfer slide rail 107 and a transfer cylinder 108 are provided on the top plate of the first frame 102. The extension directions of the transverse transfer slide rail 107 and the transfer cylinder 108 are both perpendicular to the arrangement direction of the material handling units 101. The transfer mechanism 103 includes a mounting base 104, a lifting cylinder 105, and a lifting bracket 106. The lifting cylinder 105 is connected to the mounting base 104, and the lifting bracket 106 is located at the bottom of the mounting base 104 and connected to the output end of the lifting cylinder 105. Twenty-four material handling units 101 are arranged on the lifting bracket 106. The mounting base 104 is slidably mounted on the transverse transfer slide rail 107, and the output end of the transfer cylinder 108 is connected to the mounting base 104.

[0048] After the filter-containing jig 100 is transferred to the filter unloading device, the transfer mechanism 103 is positioned directly above the jig 100. First, the lifting cylinder 105 lowers the lifting bracket 106, bringing all the picking units 101 close to their corresponding filters. Based on the signal from the pre-inspection process, only the independent drive device corresponding to the qualified product section activates, causing the picking unit 101 to grab the qualified filters, while the unqualified filters remain on the jig 100. After the qualified products are grabbed, the lifting cylinder 105 raises the lifting bracket 106, lifting the qualified filters. Subsequently, the transfer cylinder 108 drives the transfer mechanism 103 to slide along the transverse transfer rail 107, moving the picking unit 101 directly above the qualified product channel 201. The lifting cylinder 105 again lowers the lifting bracket 106, and the independent drive device activates the picking unit 101, causing the filters to fall onto the qualified product channel 201. Finally, the lifting cylinder 105 rises and resets, the independent drive device resets, and the transfer cylinder 108 drives the transfer mechanism 103 to slide and reset in the opposite direction along the transverse transfer slide rail 107.

[0049] Preferably, since the arrangement length of the twenty-four sets of material picking units 101 is relatively long, to ensure the stability of the transfer mechanism 103, two sets of transfer mechanisms 103 can be provided, with each set of transfer mechanisms 103 having twelve sets of material picking units 101. Correspondingly, a transfer slide plate 127 is slidably mounted on the transverse transfer slide rail 107, and the mounting seats 104 of both sets of transfer mechanisms 103 are mounted on the transfer slide plate 127. The output end of the transfer cylinder 108 is connected to the transfer slide plate 127, thereby indirectly connecting to the mounting seat 104. The output end of the transfer cylinder 108 drives the transfer mechanism 103 to move by driving the transfer slide plate 127 to slide along the transverse transfer slide rail 107. Of course, in other embodiments, the number of transfer mechanisms 103 can be adjusted according to actual conditions. Meanwhile, to ensure the accuracy of the position when the output end of the transfer cylinder 108 extends to the far end, a second limiting member 126 opposite to the transfer slide plate 127 is provided on the top of the top plate of the first frame 102. The second limiting member 126 can be a limiting block or an adjustable limiting screw, etc. When the output end of the transfer cylinder 108 extends to the far end, the transfer slide plate 127 abuts against the second limiting member 126 to ensure the accuracy of the extension distance.

[0050] Preferably, based on Figure 3 and Figure 4 As shown, the mounting base 104 is vertically provided with a first linear bearing 121, and the top of the lifting bracket 106 is provided with a first lifting shaft 122 that slides through the first linear bearing 121. When the lifting cylinder 105 drives the lifting bracket 106 to rise or fall, the first lifting shaft 122 slides along the first linear bearing 121. The first linear bearing 121 and the first lifting shaft 122 serve as guides. Simultaneously, to increase the stability of the lifting, four first linear bearings 121 are arranged around the lifting cylinder 105, and four first lifting shafts 122 are respectively slidably disposed on the top of the lifting bracket 106. In other embodiments, the number of first linear bearings 121 and first lifting shafts 122 can be adjusted according to actual conditions.

[0051] Preferably, a material-receiving limiting plate 123 is installed on the top of the first lifting shaft 122, and a first limiting member 124 is provided on the material-receiving limiting plate 123 located on the top of the lifting cylinder 105. The first limiting member 124 can be a limiting block or an adjustable limiting screw, etc. When the output end of the lifting cylinder 105 extends downward and the material-receiving unit 101 moves to a suitable position above the material, the first limiting member 124 abuts against the top of the lifting cylinder 105, thereby ensuring the accuracy of the extension distance of the output end of the lifting cylinder 105.

[0052] Furthermore, based on Figures 3 to 5As shown, the lifting bracket 106 is equipped with a mounting plate 109 and a material ejection plate 110 located at the bottom of the mounting plate 109. The mounting plate 109 and the material ejection plate 110 are connected to each other via a vertical plate 125. The independent driving device is a vertical cylinder 111, which is mounted on the top of the mounting plate 109 and extends to the bottom of the mounting plate 109. The material handling unit 101 includes a material handling rod 112 and a vertical material ejection cylinder 113. The vertical material ejection cylinder 113 is mounted on the bottom end of the material ejection plate 110, and the material handling rod 112 slides vertically through the vertical material ejection cylinder 113. The top end of the material handling rod 112 is connected to the output end of the vertical cylinder 111. The bottom end of the material handling rod 112 is provided with a locking part 114. The vertical cylinder 111 drives the material-taking rod 112 to slide along the vertical ejector cylinder 113, so that the locking part 114 can extend out or retract to the bottom end of the vertical ejector cylinder 113. The locking part 114 is located above the fixture 100 and the qualified product channel 201.

[0053] The locking part 114 is used to engage with the filter. When the filter needs to be picked up, the vertical cylinder 111 is activated, its output shaft extends and drives the locking part 114 at the bottom of the picking rod 112 to extend out of the bottom end of the vertical discharge cylinder 113, where the locking part 114 engages with the filter. At this time, the lifting cylinder 105 drives the lifting bracket 106 to rise, and the filter can rise along with the locking part 114. When the filter needs to be lowered, the vertical cylinder 111 is activated, its output shaft retracts and drives the locking part 114 at the bottom of the picking rod 112 to retract back into the vertical discharge cylinder 113, whereby the filter can be detached under the misaligned contact between the vertical discharge cylinder 113 and the locking part 114.

[0054] Furthermore, based on Figure 5 As shown, a first groove 115 is formed on the top of the ejector plate 110, and a vertical ejector cylinder 113 passes through the bottom wall of the first groove 115 through the ejector plate 110. A clamping plate 117 is connected to the top of the ejector plate 110, and a second groove 118 is formed on the side wall of the clamping plate 117 facing the first groove 115. The picking rod 112 passes through the clamping plate 117 and the second groove 118 from the top, and finally passes into the vertical ejector cylinder 113. A first retaining edge 116 is provided on the outer side wall of the top of the vertical ejector cylinder 113, which rests on the bottom wall of the first groove 115. The ejector plate 110 is bolted or riveted to the clamping plate 117. An elastic element 119 is held between the bottom wall of the first retaining edge 116 and the second groove 118. The elastic element 119 is preferably a spring, which is sleeved on the outside of the picking rod 112. The spring presses the first retaining edge 116 against the bottom wall of the first groove 115 to maintain the stability of the vertical ejector cylinder 113. In other embodiments, the elastic element 119 may also be an elastic sleeve or a spring sheet, etc.

[0055] During use, the height of the filters on the fixture 100 may fluctuate. When the vertical cylinder 111 moves the lifting bracket 106 downward, the bottom end of the vertical feed cylinder 113 may come into contact with part of the filter. The elastic element 119 can provide a certain buffering effect and allow the vertical feed cylinder 113 to have a certain vertical movement margin, ensuring that the vertical feed cylinder 113 will not crush the filter.

[0056] Preferably, based on Figure 5 As shown, the outermost top wall of the picking rod 112 is provided with a second retaining edge 128 that movably abuts against the top of the clamping plate 117. When the vertical cylinder 111 drives the picking rod 112 down to the engaging part 114 and engage with the filter, the second retaining edge 128 abuts against the top of the clamping plate 117 to limit the picking rod 112 from moving further down, thus ensuring the accuracy of the moving distance of the picking rod 112.

[0057] In this embodiment, the filter is a liquid medicine filter. Based on Figure 4 , Figure 6 and Figure 8 As shown, the top of the liquid filter has a columnar protrusion, and the locking part 114 is a hollow retaining ring. The inner side of the hollow retaining ring is interference-fitted with the outer wall of the columnar protrusion on the top of the liquid filter. Two elastic notches 120 are formed around the bottom of the hollow retaining ring to clamp the liquid filter elastically. Of course, in other embodiments, three or four elastic notches 120 can also be provided around the bottom of the hollow retaining ring.

[0058] In other embodiments, the filter may also be an air filter. Based on Figure 4 , Figure 6 and Figure 9 As shown, the top of the air filter has a groove structure, and the snap-fit ​​part 114 is a hollow snap ring. The outer side of the hollow snap ring is interference-fitted with the inner sidewall of the groove structure on the top of the air filter.

[0059] Furthermore, based on Figure 1 , Figure 7 , Figure 10 and Figure 11As shown, the non-conforming product unloading device 3 includes a second frame 301, a top-loading assembly, and an air blowing device. The second frame 301 is also a vertically placed rectangular frame structure. A lifting cylinder 302 is installed on the second frame 301, and the top-loading assembly is located on the top of the second frame 301 and connected to the output end of the lifting cylinder 302. The lifting cylinder 302 can drive the lifting assembly to move up and down. Twenty-four top-loading rods 303 are arranged on the top of the top-loading assembly, each corresponding to the bottom of one of the twenty-four filter slots 200 on the fixture 100. The air blowing device includes an air outlet pipe 305, which is connected to an external air source. The air outlet pipe 305 has twenty-four air outlets 304, each corresponding to the top of one of the filter slots 200 on the fixture 100, and the air outlets 304 are oriented towards the non-conforming product channel 202. The gas blown out by the external air source flows along the air outlet pipe 305 and is blown from the air outlet end 304 toward the top of the filter tank 200.

[0060] In operation, after the qualified products are removed by the transfer device 1, the lifting cylinder 302 drives the lifting assembly upward, and the lifting rod 303 lifts the unqualified products remaining on the fixture 100 from the bottom, causing the unqualified products to detach from the filter tank 200. At this time, the external air source is activated, and gas is blown out from the air outlet 304, blowing the unqualified products down into the unqualified product channel 202. Since the filter tank 200 where the qualified products were located on the fixture 100 is now empty, all twenty-four lifting rods 303 can rise simultaneously without affecting the separate transfer of qualified and unqualified products.

[0061] Preferably, to ensure that defective products fall precisely into the defective product channel 202 when blown down, the entrance to the defective product channel 202 is located at the bottom edge of the fixture 100. Simultaneously, fixing both ends of the air outlet pipe 305 to the supporting device 2, rather than directly connecting it to the second frame 301 or the lifting assembly, ensures the relative position between the air outlet pipe 305 and the defective product channel 202. The air outlet pipe 305 will not move with the lifting assembly, ensuring stability when connected to an external air source.

[0062] Furthermore, based on Figure 7 , Figure 11 and Figure 12 As shown, the top-feeding assembly includes a support plate 306 and a fixing plate 307 connected to the top of the support plate 306. The bottom of the support plate 306 is connected to the output end of the lifting cylinder 302. A slot 308 is formed on the side wall of the fixing plate 307 facing the support plate 306. The top-feeding rod 303 is inverted "T" shape, with a third retaining edge 309 on its bottom outer side wall. The top-feeding rod 303 passes through the top wall of the slot 308 and exits the top of the fixing plate 307, with the third retaining edge 309 clamping between the support plate 306 and the top wall of the slot 308. The support plate 306 and the fixing plate 307 are bolted or riveted together to clamp and fix the top-feeding rod 303.

[0063] Preferably, based on Figure 7 and Figure 11 As shown, a second linear bearing 310 is vertically mounted on the top of the second frame 301, and a second lifting shaft 311 is slidably mounted on the bottom of the support plate 306, passing through the second linear bearing 310. The second linear bearing 310 and the second lifting shaft 311 can increase the stability of the lifting assembly during lifting. Furthermore, two or more sets of the second linear bearing 310 and the second lifting shaft 311 can be provided, with multiple sets of the second linear bearing 310 and the second lifting shaft 311 symmetrically arranged on both sides of the output end of the lifting cylinder 302 to ensure the balance of the lifting assembly.

[0064] Furthermore, based on Figure 1 and Figure 10 As shown, the carrying device 2 includes a guide box 203 and a collection box 204 located at the bottom of the guide box 203. Both the qualified product channel 201 and the unqualified product channel 202 are located within the guide box 203. The guide box 203 has a double-layer structure, with the qualified product channel 201 located at the top of the unqualified product channel 202. The guide box 203 is equipped with a collection trough 205, which is connected to the end of the qualified product channel 201 furthest from the transfer device 1. The qualified product channel 201 is inclined towards the collection trough 205. When a qualified filter is transferred to the qualified product channel 201, it rolls down the inclined qualified product channel 201 under gravity into the collection trough 205 for collection. The collection box 204 is located directly below the end of the unqualified product channel 202 furthest from the unqualified product unloading device 3, and the unqualified product channel 202 is inclined towards the collection box 204. When a defective filter is transferred to the defective product channel 202, it rolls down along the inclined defective product channel 201 under the action of gravity and falls into the collection box 204 for recycling.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
