[0064] The terms "first", "second", "third" (if any) in the description, claims and drawings of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data may be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0065] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0066] In the prior art, when assembling a check valve, manual operations such as welding, inspection, and coding are required. However, it is difficult to ensure the quality of the operations during manual work, and the labor intensity of the workers is relatively high, resulting in a low assembly efficiency of the check valve. If separate devices are used to complete the operations of welding, inspection, and coding respectively, manual transfer of the check valve between the devices is still needed, and the labor intensity of the workers remains high and the assembly efficiency is still low.

[0067] After repeated thinking and verification, the inventor of the present application found that if a conveying mechanism is used to drive the check valve to move along a preset path, different processing stations are respectively arranged on the preset path, and a plurality of processing mechanisms are arranged on the edge of the conveying mechanism. When the conveying mechanism drives the check valve to move to different processing stations, the corresponding processing mechanism for the processing station can perform corresponding processing on the check valve. After processing, it is driven by the conveying mechanism to the next processing station, and the subsequent processing of the check valve is performed by the next processing mechanism. A blanking mechanism is provided to blank the processed check valve, and a packing mechanism is provided to pack the check valve blanked by the blanking mechanism. In this way, during the assembly process of the check valve, the operations of welding, inspection, coding, and packing are automatically completed without manual work, and there is no need for manual transfer between adjacent operations.

[0068] In view of this, the inventor of the present application designed a check valve assembly device. The conveying mechanism drives the check valve to move along a preset path, and the preset path movement includes a welding station, an inspection station, a coding station, and a blanking station. The check valve located at the welding station is welded by a welding mechanism, the airtightness of the check valve located at the inspection station is detected by an inspection mechanism, the check valve located at the coding station is coded by a coding mechanism, the check valve on the conveying mechanism is blanked by a blanking mechanism, and the check valve blanked by the blanking mechanism is packed by a packing mechanism. The use of the check valve assembly device automatically completes the operations of welding, inspection, coding, and packing during the assembly process of the check valve, improves the assembly efficiency of the check valve, reduces the labor intensity of the workers, and improves the assembly quality of the check valve.

[0069] Refer to Figure 1 and Figure 2As shown in the figure, the one-way valve assembly device provided by the embodiment of the present application includes a frame 1, a conveying mechanism 2, a welding mechanism 3, an inspection mechanism 4, a coding mechanism 5, a blanking mechanism 6, and a packing mechanism 7. The conveying mechanism 2 is installed on the frame 1, and the conveying mechanism 2 is used to drive the one-way valve 10 to move along a preset path, and the preset path includes a loading station, a welding station, an inspection station, a coding station, and a blanking station. The welding mechanism 3 is installed on the frame 1, and the welding mechanism 3 is configured to weld the one-way valve 10 located at the welding station. The inspection mechanism 4 is installed on the conveying mechanism 2, and the inspection mechanism 4 is configured to perform airtightness inspection on the one-way valve 10 located at the inspection station. The coding mechanism 5 is installed on the frame 1, and the coding mechanism 5 is configured to code the one-way valve 10 located at the coding station. The blanking mechanism 6 is configured to blank the one-way valve 10 located at the blanking station. The packing mechanism 7 is configured to pack the one-way valve 10 after blanking by the blanking mechanism 6.

[0070] Among them, the frame 1 is a frame structure, and a top plate is provided at the top of the frame 1. The conveying mechanism 2, the welding mechanism 3, the inspection mechanism 4, the coding mechanism 5, and the blanking mechanism 6 can be respectively arranged on the top plate. Schematically, the one-way valve 10 can be loaded onto the loading station by a loading device such as a manipulator, and the conveying mechanism 2 drives the one-way valve 10 to sequentially pass through the welding station, the inspection station, and the coding station along the preset path from the loading station and move to the blanking station. Schematically, a plurality of in-place detection sensors are arranged on the conveying mechanism 2. When the one-way valve 10 moves to a specific station, the corresponding in-place detection sensor can output a signal to control the conveying mechanism 2 to stop conveying and control the corresponding processing mechanism to process the one-way valve 10 at this station.

[0071] Exemplarily, as Figure 3 shown, the coding mechanism 5 includes a coding bracket 52 installed on the top plate of the frame 1 and a coding machine 51 installed on the coding bracket 52. Among them, the coding machine 51 can be a laser coding machine or a spraying coding machine, etc. When the conveying mechanism 2 drives the one-way valve 10 to move to the coding station, the coding machine 51 can code the one-way valve 10 at the coding station.

[0072] In a possible implementation manner, as Figure 4As shown in the figure, the blanking mechanism 6 includes a second lifting cylinder 61, a second translation cylinder 62 mounted on the second lifting cylinder 61, and a second jaw cylinder 63 mounted on the second translation cylinder 62. The second lifting cylinder 61 can adjust the jaw height of the second jaw cylinder 63, and the second translation cylinder 62 can laterally move the second jaw cylinder 63. Exemplarily, the second lifting cylinder 61 can be mounted on the top plate of the frame 1 through a bracket. After the conveying mechanism 2 drives the check valve 10 to move to the blanking station, the check valve 10 is clamped by the second jaw cylinder 63 to complete blanking. Optionally, a conveyor belt can be provided on the frame 1. After the blanking mechanism 6 removes the check valve 10 from the conveying mechanism 2, it can be placed on the conveyor belt, and the conveyor belt transports the check valve 10 to the packing mechanism 7. Exemplarily, the check valve assembly device further includes a cabinet mounted on the frame 1, and the conveying mechanism 2, the welding mechanism 3, the detection mechanism 4, the coding mechanism 5, and the blanking mechanism 6 are all located inside the cabinet.

[0073] In the check valve assembly device provided by the present application, when the feeding device transports the check valve 10 to the feeding station of the conveying mechanism 2, the conveying mechanism 2 can drive the check valve 10 to move along a preset path. When the check valve 10 moves from the feeding station to the welding station on the preset path, the welding mechanism 3 can weld the check valve 10. When the check valve 10 moves from the welding station to the detection station on the preset path, the detection mechanism 4 can perform a airtightness detection on the check valve 10. When the check valve 10 moves from the detection station to the coding station on the preset path, the coding mechanism 5 can code the check valve 10. When the check valve 10 moves from the coding station to the blanking station on the preset path, the blanking mechanism 6 can blank the check valve 10. The packing mechanism 7 packs the check valve 10 blanked by the blanking mechanism 6. In this way, during the assembly process of the check valve 10, the welding, detection, coding, and packing processes are automatically completed, without manual operation, and there is no need for manual transfer between adjacent processes. The assembly efficiency of the check valve 10 is improved, the labor intensity of the staff is reduced, and the assembly quality of the check valve 10 is effectively improved.

[0074] In one embodiment, please refer to Figures 5 - 8, the conveying mechanism 2 includes a first conveying unit 21, a second conveying unit 22 and a transfer unit 23. The first conveying unit 21 includes a first support plate 211 and a first pushing assembly mounted on the frame 1. A first channel 2111 is formed on the first support plate 211, and the feeding station and the welding station are respectively located on the first channel 2111. The second conveying unit 22 includes a second support plate 221 and a second pushing assembly mounted on the frame 1. A second channel 2211 is formed on the second support plate 221, and the detection station, the coding station and the discharging station are respectively located on the second channel 2211. The one-way valve assembly device further includes a first carrier 8 for carrying the one-way valve 10 in the first channel 2111 and a second carrier 9 for carrying the one-way valve 10 in the second channel 2211. The first pushing assembly is used to drive the first carrier 8 to move in the first channel 2111, and the second pushing assembly is used to drive the second carrier 9 to move in the second channel 2211. The transfer unit 23 is used to transfer the one-way valve 10 located downstream of the welding station in the first channel 2111 to a position upstream of the detection station in the second channel 2211.

[0075] Exemplarily, the first pushing assembly includes a first welding pushing member 216, a second welding pushing member 217 and a third welding pushing member 218. Taking the first welding pushing member 216 as an example, it includes a driving cylinder and a pushing member mounted on the driving cylinder. The driving cylinder drives the pushing member to push the first carrier 8 to move in the first channel 2111. The second pushing assembly includes a first detection pushing member 222, a second detection pushing member 223 and a third detection pushing member 224. Each detection pushing member can push the second carrier 9 to move in the second channel 2211.

[0076] As Figure 8 shown, in a possible implementation manner, the transfer unit 23 includes a first lifting cylinder 231, a first translation cylinder 232 mounted on the first lifting cylinder 231, and a first jaw cylinder 233 mounted on the first translation cylinder 232. The first lifting cylinder 231 can be mounted on the second support plate 221 through a bracket. The first jaw cylinder 233 can pick up the one-way valve 10 located downstream of the welding station in the first channel 2111 and transfer it to a position upstream of the detection station in the second channel 2211.

[0077] As Figure 9 and Figure 10 shown, schematically, the first carrier 8 can press the first shell and the second shell of the one-way valve 10 to prevent the first shell and the second shell of the one-way valve 10 from separating in the first channel 2111 before welding. While fixing the one-way valve 10, the second carrier 9 can ensure that all the interfaces of the one-way valve 10 protrude from the second carrier 9, facilitating the airtightness detection of the welded one-way valve 10 by the detection mechanism 4.

[0078] In this structure, the loading station and the welding station are arranged on the first channel 2111. The first carrier 8 is used to carry the one-way valve 10 in the first channel 2111, which can prevent the first housing and the second housing of the one-way valve 10 from separating in the first channel 2111 before welding, facilitating the welding mechanism 3 to weld the one-way valve 10. The detection station, the coding station and the unloading station are arranged on the second channel 2211. The second carrier 9 is used to carry the one-way valve 10 in the second channel 2211, facilitating the airtightness detection of the one-way valve 10 and subsequent coding and unloading.

[0079] Please continue to refer to Figure 9 and Figure 10 In one embodiment, the first carrier 8 includes a first plate body 81, a first fixture 82 mounted on the first plate body 81, and a pressing member 83 rotatably mounted on the first fixture 82. The first fixture 82 is used to carry the one-way valve 10, and the pressing member 83 is used to press the first housing and the second housing of the one-way valve 10 together. The second carrier 9 includes a second plate body 91 and a second fixture 92 mounted on the second plate body 91. The second fixture 92 is used to carry the one-way valve 10.

[0080] Exemplarily, the first fixture 82 can be fixed to the first plate body 81 by fasteners. A receiving groove matching the shape of the second housing is formed at the top of the first fixture 82. The pressing member 83 has an approximate "L" shape, and this "L" shape can be rotatably mounted on the first fixture 82 through a pin. After the first housing and the second housing of the one-way valve 10 are respectively placed on the first fixture 82, the second end of the "L" shape is used to press the first housing to press the first housing and the second housing together. Among them, a spring 84 is connected between the first end of the pressing member 83 and the first fixture 82, and this spring 84 is used to drive the second end of the pressing member 83 to press the first housing. Optionally, a limit screw 85 is installed at a position near the top of the pressing member 83, and the pressing member 83 can be limited by the limit screw 85 abutting against the first fixture 82.

[0081] A receiving groove matching the shape of the second housing is formed at the top of the second fixture 92. Since the first housing and the second housing are welded, the first housing and the second housing will not separate. It is worth mentioning that both interfaces of the second housing extend out of the second fixture 92, facilitating the detection mechanism 4 to perform airtightness detection on the one-way valve 10 and subsequent coding and unloading.

[0082] In this structure, the first carrier 8 can press the first housing and the second housing together, facilitating the movement of the one-way valve 10 in the first channel 2111 and the welding of the one-way valve 10. The second carrier 9 can ensure that there is no interference with the detection mechanism 4 during the airtightness detection of the one-way valve 10 and is convenient for subsequent coding and unloading.

[0083] In one embodiment, Figure 6 , Figure 11 and Figure 12 As shown, the welding mechanism 3 includes a first positioning component 31, a welding machine 32 installed on the frame 1, a welding head 33 installed on the welding machine 32, and a position sensor for detecting whether the first carrier 8 has reached the welding station. The first positioning component 31 includes a first positioning member 311 that can move relative to the first support plate 211, and the first carrier 8 is provided with a first positioning groove 811 for the end of the first positioning member 311 to extend into.

[0084] The first positioning assembly 31 further includes a first positioning cylinder 312 mounted on the first support plate 211, and the first positioning member 311 is mounted on the output end of the first positioning cylinder 312. The end of the first positioning member 311 has a guide surface. A positioning groove can be provided on the first plate body 81, and the shape of the positioning groove matches the shape of the end of the first positioning member 311. When the end of the first positioning member 311 extends into the first positioning groove 811, the position of the first carrier 8 can be fine-tuned to ensure that the welding mechanism 3 can accurately weld the one-way valve 10.

[0085] The position sensor can be fixed on the first support plate 211 through the sensor bracket 34. The position sensor is electrically connected to the first positioning assembly 31. When the first carrier 8 carrying the one-way valve 10 moves to the welding station, the position sensor outputs a signal to control the first positioning assembly 31 to accurately position the first carrier 8. Exemplarily, the welder 32 can be an ultrasonic welder 32, which can drive the welding head 33 to rise and fall. When the welding head 33 contacts the one-way valve 10, the first shell and the second shell are welded and fixed by vibration.

[0086] In this structure, the position sensor can control the operation of the first positioning component 31 , and the first positioning component 31 can accurately position the first carrier 8 in the welding station to ensure the welding quality of the one-way valve 10 .

[0087] In one possible implementation, the one-way valve assembly device also includes an unlocking drive installed on the first support plate 211 and a first unlocking member installed on the unlocking drive, the first unlocking member is used to push the first end of the clamping member 83 to make the second end of the clamping member 83 disengage from the one-way valve 10, wherein the clamping member 83 is located in the welding station.

[0088] Exemplarily, the unlocking drive and the first unlocking member are arranged on the side of the welding station away from the first positioning assembly 31. A cylinder can be used as the unlocking drive. The first unlocking member has a pushing portion for pushing the first end of the clamping member 83. After the first positioning assembly 31 positions the first carrier 8, the unlocking drive drives the first unlocking member to move to push the first end of the clamping member 83.

[0089] In this embodiment, by providing an unlocking driving member and a first unlocking member, before welding the one-way valve 10, the first end of the pressing member 83 is pushed against by the first unlocking member so that the second end of the pressing member 83 is separated from the one-way valve 10, avoiding interference between the pressing member 83 and the welding head 33 during the welding of the one-way valve 10.

[0090] Please refer to Figure 6 and Figure 13 , in one embodiment, the first pushing assembly includes a feeding driving member 214 mounted on the first support plate 211 and a second unlocking member 215 mounted on the feeding driving member 214. The second unlocking member 215 is used to push the first carrier 8 located at the feeding station. An extension section 2151 is provided at the end of the second unlocking member 215, and the extension section 2151 is used to push the first end of the pressing member 83 so that the second end of the pressing member 83 is separated from the first jig 82.

[0091] Exemplarily, a cylinder can be used as the feeding driving member 214, which can be fixed on the top plate of the frame 1 through a bracket. The second unlocking member 215 can be fixed to the output end of the feeding driving member 214 through a fastener. Figure 13 It is shown that a stepped portion is provided at the end of the second unlocking member 215. When the feeding driving member 214 drives the second unlocking member 215 to move, the stepped portion can push against the end of the first plate body 81 to move the first carrier 8 in the first channel 2111. When the first carrier 8 is located at the feeding station, the extension section 2151 of the second unlocking member 215 can push against the first end of the pressing member 83 so that the second end of the pressing member 83 is separated from the first jig 82.

[0092] With this structure, the feeding driving member 214 and the second unlocking member 215 can push the first carrier 8 to move in the first channel 2111. In addition, by pushing against the first end of the pressing member 83 with the extension section 2151, the second end of the pressing member 83 is separated from the first jig 82, facilitating the feeding device to place the one-way valve 10 on the first jig 82.

[0093] In one embodiment, as Figure 6 、 Figure 11 and Figure 14 shown, the first conveying unit 21 further includes a plurality of first edge guards 212 mounted on the first support plate 211. The plurality of first edge guards 212 form a first channel 2111 on the first support plate 211. A transfer station is provided at a position downstream of the welding station in the first channel 2111. The one-way valve assembly device further includes a third unlocking member 213 mounted on the edge guard. The third unlocking member 213 is used to push the first end of the pressing member 83 when the first carrier 8 passes through the transfer station so that the second end of the pressing member 83 is separated from the one-way valve 10.

[0094] Schematically, each first edge stop 212 is a strip structure. The first edge stop 212 can be fixed to the first support plate 211 by fasteners. The boundary of the first channel 2111 can be defined by the first edge stop 212. Further, a first pressing piece 219 can be provided on the first edge stop 212, and the edge of the first pressing piece 219 extends beyond the first edge stop 212. When the first carrier 8 moves in the first channel 2111, the part of the first pressing piece 219 that extends beyond the first edge stop 212 abuts against the edge of the first plate body 81. The first pressing piece 219 can prevent the first carrier 8 from bouncing when moving in the first channel 2111.

[0095] In other embodiments, a groove can also be opened on the first support plate 211 as the first channel 2111, which is not limited uniquely here.

[0096] It can be understood that the third unlocking member 213 is located at the transfer station, and the third unlocking member 213 is installed on the top of the first edge stop 212. Wherein, the edge of the third unlocking member 213 extends beyond the first edge stop 212. Figure 14 It is shown that an arc-shaped block is provided on the top of the third unlocking member 213. When the first carrier 8 approaches the transfer station, the first end of the pressing member 83 is located above the part of the third unlocking member 213 that extends beyond the first edge stop 212. As the first carrier 8 continues to move, the arc-shaped block on the third unlocking member 213 pushes against the first end of the pressing member 83 so that the second end of the pressing member 83 disengages from the one-way valve 10.

[0097] With this structure, the first carrier 8 in the first channel 2111 can be limited by the first edge stop 212. The third unlocking member 213 is provided on the first edge stop 212, so that when the first carrier 8 is at the transfer station, the second end of the pressing member 83 disengages from the one-way valve 10, facilitating the transfer unit 23 to remove the one-way valve 10 from the first carrier 8.

[0098] In other embodiments, a plurality of second edge stops can be provided on the second support plate 221, and the second channel 2211 is defined by the plurality of second edge stops. A second pressing piece can be provided on the top of the second edge stop, and the edge of the second pressing piece extends beyond the second edge stop. The part of the second pressing piece that extends beyond the second edge stop is used to abut against the edge of the second plate body 91 to prevent the second carrier 9 from bouncing when moving in the second channel 2211.

[0099] Such as Figure 1 、 Figure 7 and Figure 15As shown, in a possible implementation, the detection mechanism 4 includes a plurality of detection units 41 arranged side by side. Each detection unit 41 includes three plugging members 411, and each plugging member 411 is respectively arranged in one-to-one correspondence with the interfaces of the one-way valve 10 for plugging the interfaces. One of the plugging members 411 is provided with a pipeline communicating with the corresponding interface, and leak detectors communicating with the corresponding interfaces are respectively provided on the other two plugging members 411.

[0100] Schematically, the detection unit 41 further includes detection cylinders 412 respectively used to drive the three plugging members 411 to move, and each detection cylinder 412 can be installed on the second support plate 221 through a bracket. In this embodiment, the number of detection units 41 is not limited, and those skilled in the art can set it according to actual needs. After the second carrier 9 drives the one-way valve 10 to move to the detection station, the three plugging members 411 of the detection unit 41 respectively plug the three interfaces of the one-way valve 10. During the detection process, gas is introduced into the one-way valve 10 and the gas in the one-way valve 10 is extracted through the pipeline on one of the plugging members 411, and it is determined whether the welded one-way valve 10 is qualified according to the leak detectors on the other two plugging members 411.

[0101] Through the above settings, automatic detection of the airtightness of the one-way valve 10 can be realized. The detection mechanism 4 can simultaneously detect the airtightness of multiple one-way valves 10 through multiple detection units 41, which is beneficial to improving the assembly efficiency of the one-way valve 10.

[0102] As Figure 7 、 Figure 15 and Figure 16 As shown, in a specific embodiment, the detection mechanism 4 further includes a plurality of positioning units 42 respectively corresponding to the positions of the detection units 41. The positioning unit 42 includes a second positioning member 421 capable of moving relative to the second support plate 221, and a second positioning groove for the end of the second positioning member 421 to extend into is provided on the second carrier 9.

[0103] Exemplarily, the positioning unit 42 further includes a second positioning cylinder 422, which can be installed on the top plate of the frame 1 through a bracket, and the second positioning member 421 is installed on the output end of the second positioning cylinder 422. Among them, a guiding surface is provided at the top end of the second positioning member 421, and the second positioning groove is opened on the bottom surface of the second plate body 91 and the shape of the second positioning groove matches the shape of the top end of the second positioning member 421. When the top end of the second positioning member 421 extends into the second positioning groove, the position of the second carrier 9 can be finely adjusted to ensure that each detection unit 41 can stably detect the airtightness of the corresponding one-way valve 10.

[0104] As Figure 7 and Figure 17As shown, in a possible implementation, the second pushing component includes two electric lateral driving members 225 respectively located on opposite sides of the detection mechanism 4. An elevating driving member 226 is respectively installed on each electric lateral driving member 225, and the output end of the elevating driving member 226 is used to drive the second carrier 9 to move.

[0105] Among them, the electric lateral driving member 225 can use an electric cylinder, and the stroke of the electric lateral driving member 225 can be accurately controlled through programming. A cylinder can be used as the elevating driving member 226, and the elevating driving member 226 is installed on the output end of the electric lateral driving member 225. Schematically, the second pushing component further includes a limiting bracket installed on the electric lateral driving member 225 and a positioning pin slidably installed on the limiting bracket. The bottom end of the positioning pin is fixedly connected to the output end of the elevating driving member 226. Optionally, a slot cooperating with the positioning pin can be provided at the side end of the second plate body 91.

[0106] When detecting the one-way valve 10, the electric lateral driving member 225 and the elevating driving member 226 on one side of the detection mechanism 4 can drive multiple second carriers 9 into the detection station. After multiple one-way valves 10 in the detection station are detected, the electric lateral driving member 225 and the elevating driving member 226 on one side of the detection mechanism 4 drive multiple second carriers 9 into the detection station again and push out the multiple second carriers 9 originally in the detection station. The electric lateral driving member 225 and the elevating driving member 226 on the other side of the detection mechanism 4 can drive the multiple second carriers 9 pushed out from the detection station away from the detection station.

[0107] With this structure, by setting the electric lateral driving member 225 and the elevating driving member 226, multiple second carriers 9 can be driven to accurately enter the detection station, facilitating the detection mechanism 4 to detect multiple one-way valves 10.

[0108] Please refer to Figure 1 、 Figure 2 and Figure 18 , in a possible implementation, the packing mechanism 7 includes a turntable 71, a plurality of cartridges 72 annularly arranged on the turntable 71, and a rotary driving member connected to the turntable 71 for driving the turntable 71 to rotate. The cartridges 72 are used to accommodate the one-way valves 10 after the feeding mechanism 6 feeds. A full-material detection sensor is installed on each cartridge 72, and each full-material detection sensor is electrically connected to the rotary driving member.

[0109] Exemplarily, the packing mechanism 7 further includes a packing bracket 73, and the turntable 71, the cartridge 72 and the rotary driving member are all installed in the packing bracket 73. Among them, a servo motor can be used as the rotary driving member, and the output shaft of the rotary driving member is fixedly connected to the turntable 71. The number of the cartridges 72 in this embodiment is not restrictive, and those skilled in the art can set it according to actual needs. During the process of packing the one-way valve 10, the cartridge 72 is used to accommodate the one-way valve 10 after being discharged by the feeding mechanism 6. When the full material detection sensor detects that the cartridge 72 is full, it outputs a signal to the rotary driving member to drive the turntable 71 to rotate, so that another cartridge 72 can accommodate the one-way valve 10 after being discharged by the feeding mechanism 6.

[0110] Through the above settings, the packing mechanism 7 can automatically pack the one-way valve 10 discharged by the feeding mechanism 6.

[0111] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
