[0044] Solenoid valves are a crucial component of washing machine control systems, and their production process directly impacts product yield and stability. Currently, the industry faces challenges such as low assembly precision, inadequate assembly, and unstable water flow, failing to meet the needs of both manufacturers and users.

[0045] The present invention proposes a solenoid valve assembly line. Figures 1 to 10 The following is a specific drawing of an embodiment of the solenoid valve assembly line proposed in this application. The solenoid valve assembly line will be described in detail in conjunction with the specific drawing.

[0046] See also Figures 1 to 10The solenoid valve assembly line 1000 is used to install the plug plate 3000 and the mounting plate 4000 to the valve body 2000. It is characterized in that the solenoid valve assembly line 1000 is provided with a loading station, a plug plate 3000 assembly station, a mounting plate 4000 assembly station and a unloading station. The solenoid valve assembly line 1000 includes a conveying device 1, a plug plate assembly device 2 and a mounting plate assembly device 3. The conveying route of the conveying device 1 is arranged to the loading station, the plug plate 3000 assembly station, The assembly station of the mounting plate 4000 and the unloading station are used to transport the valve body 2000; the plug-in plate assembly device 2 includes a plug-in plate loading device 21, a first transfer device 22 and a first push device 23, the plug-in plate loading device 21 is used to transport the plug-in plate 3000 to the first push device 23, the first transfer device 22 has a movable stroke between the first push device 23 and the plug-in plate 3000 assembly station, so as to transfer the valve body 2000 at the plug-in plate 3000 assembly station to the first push device 23. 00 is transferred to the position corresponding to the plug plate 3000 on the first pushing device 23, and the valve body 2000 after assembly is transferred back to the plug plate 3000 assembly station. The first pushing device 23 is used to push the plug plate 3000 to plug into the valve body 2000; the installation plate assembly device 3 includes an installation plate feeding device 31, a second transfer device 32 and a second pushing device 33. The installation plate feeding device 31 is used to transport the installation plate 4000 with a notch to the second pushing device Device 33, the second transfer device 32 has a movable stroke between the second pushing device 33 and the assembly station of the mounting plate 4000, so as to transfer the valve body 2000 at the assembly station of the mounting plate 4000 to the gap of the mounting plate 4000 on the second pushing device 33, and to transfer the assembled valve body 2000 back to the assembly station of the mounting plate 4000, and the second pushing device 33 is used to push the valve body 2000 to be clamped in the gap of the mounting plate 4000.

[0047] The technical solution of the present invention is mainly used for automatically installing the plug plate 3000 and the mounting plate 4000 on the solenoid valve body 2000. Specifically, the installation steps of the two parts are split, that is, the solenoid valve assembly line 1000 includes the plug plate assembly device 2 and the mounting plate assembly device 3, and then the conveying device 1 is laid through the above two assembly devices between the loading and unloading stations to automatically transport the valve body 2000. In this way, the automated installation of the plug plate 3000 and the mounting plate 4000 is completed. Specifically, regarding the connection structure in which the plug plate 3000 is inserted into the valve body 2000, the present application implements the insertion of the plug plate 3000 into the valve body 2000 through the first resisting device 23. Specifically, the plug plate 3000 is placed on the first resisting device 23, and then the valve body 2000 is transferred to the position on the first resisting device 23 corresponding to the plug plate 3000. The first resisting device 23 then pushes the plug plate 3000 to align and insert it into the valve body 2000, completing the automatic assembly of the plug plate 3000. The assembled valve body 2000 is returned to the conveying device 1 by the first transfer device 22 and transferred to the installation plate assembly device 3. The installation of the mounting plate 4000 is similar to that of the insert plate 3000. The valve body 2000 needs to be clamped in the notch of the mounting plate 4000. The present application uses the second push device 33 to achieve the action of clamping the valve body 2000 in the notch of the mounting plate 4000, that is, the mounting plate 4000 is placed on the second push device 33, and then the valve body 2000 is transferred to the notch where it is initially clamped in the mounting plate 4000. Then, the second push device 33 pushes the valve body 2000, so that the valve body 2000 and the mounting plate 4000 are clamped in place, completing the automatic assembly of the mounting plate 4000. The assembled valve body 2000 is sent back to the conveying device 1 by the second transfer device 32 and transferred to the unloading station to complete the automatic assembly of the solenoid valve and meet the requirements of automated assembly. In addition, it can be understood that the insert plate loading device 21 and the mounting plate loading device 31 are independent of the conveying device 1 and are auxiliary material conveying systems.

[0048] Specifically, the insert plate loading device 21 includes a vibrating disk assembly 211 and a third transfer device 212 provided at the discharge end of the vibrating disk assembly 211. The third transfer device 212 is used to transfer the insert plates 3000 located at the discharge end of the vibrating disk assembly 211 to the first push device 23. The insert plate loading device 21 is an auxiliary material conveying system independent of the conveying device 1 as described above. Therefore, the insert plate loading device 21 is an independent conveying line, and its silo conveys the insert plates 3000 to the first push device 23. It can be understood that the above-mentioned silo can be a silo that places the insert plates 3000 in a certain pattern and is transferred by a transfer mechanism; it can also be a silo that places the insert plates 3000 in a disorderly manner, which is automatically arranged after screening by a similar screening mechanism and then transferred by a transfer mechanism; it can also be a silo that places the insert plates 3000 in a disorderly manner and is automatically identified, grasped and transferred by a grasping robot. Specifically, the present application selects a combination of the vibration plate assembly 211 and the third transfer device 212. The vibration plate assembly 211 can vibrate and screen the disorderly placed plug plates 3000 and then output them according to a certain placement pattern, and then be transferred by the third transfer device 212. In this way, there is no need to prepare regularly placed material plates in advance. It is only necessary to place the plug plates 3000 materials into the vibration plate assembly 211, which is convenient for loading operations. The vibration plate assembly 211 outputs regularly arranged plug plates 3000, and the third transfer device 212 does not need to be set as a more expensive grasping robot.

[0049] Specifically, the third transfer device 212 includes a first movable component 2121 that can move between the discharge end of the vibration disk assembly 211 and the first push device 23, and a first pickup component 2122 installed on the first movable component 2121. The first pickup component 2122 can be rotated along the upper and lower axes. The third transfer device 212 only needs to transfer the neatly arranged plugboards 3000 output from the vibration disk assembly 211, so the third transfer device 212 does not require a large degree of freedom. Therefore, the present application sets the third shipping device as the first movable component 2121 and the first pickup component 2122 located on the first movable component 2121. The first movable component 2121 is used to move between the discharge end of the vibration disk assembly 211 and the first push device 23, and the first pickup component 2122 is used to pick up the plugboards 3000 for transfer. In addition, the vibration disk assembly 211 is configured to be a structure independent of the conveying device 1, so the vibration disk assembly 211 is arranged on one side of the conveying device 1, and its conveying direction is toward the conveying device 1, and the plug plate 3000 is a long structure. Generally, the conveying direction is set to be consistent with the length direction of the plug plate 3000 to reduce the volume of the conveying structure. Therefore, at this time, there is a certain angle between the plug plate 3000 and the conveying direction of the conveying device 1. In order to enable the plug plate 3000 to be normally assembled on the valve body 2000 conveyed by the conveying device 1, the present application sets the first picking component 2122 to a rotatable structure, which can adjust the angle relationship of the plug plate 3000 relative to the valve body 2000 in the horizontal direction, so that the two are corresponding to each other and then the plug plate 3000 is placed on the first pushing device 23 to meet the structural requirements.

[0050] Specifically, the first pickup assembly 2122 includes a first vacuum adsorption assembly. The primary function of the first pickup assembly 2122 is to pick up the insert plate 3000. Therefore, the first pickup assembly 2122 can be configured in a variety of ways, including but not limited to a gripper structure, an air suction structure, or the like, as long as it can achieve the pickup function. In this application, the first pickup assembly 2122 is configured as the first vacuum adsorption assembly, which is applicable to a wide range of pickup applications and facilitates debugging and use.

[0051] In addition, a first visual inspection device 2111 is provided at the discharge end of the vibration disk assembly 211. The first visual inspection device 2111 performs visual inspection on the plugboards 3000 at the discharge end of the vibration disk assembly 211 to prevent abnormal plugboards 3000 from flowing into subsequent processes, thereby ensuring the automation of the plugboard 3000 on-line process.

[0052] In addition, the first push device 23 includes a lifting device, and the lifting device is used to carry the plug plate 3000. The pushing direction of the first push device 23 can be set to any direction, and the plug plate 3000 can be pushed and inserted into the valve body 2000. There is no limitation here, and it is mainly based on actual production needs. In this application, the pushing direction of the first push device 23 is set to the up and down direction, that is, the first push device 23 is set to the lifting device. In this way, the lifting device can carry the plug plate 3000 and wait during the period of waiting for the valve body 2000 to be in place, so that the production rhythm of the solenoid valve assembly line 1000 can be arranged more freely.

[0053] Furthermore, the first transfer device 22 includes a second movable assembly 221 and a second pickup assembly 222 that is swiveled horizontally on the second movable assembly 221. The second movable assembly 221 is primarily configured to move within a three-dimensional coordinate system to move the valve body 2000 from the insert plate 3000 assembly station to a position corresponding to the first resisting device 23, and to retract the valve body 2000 from the position corresponding to the first resisting device 23 to the insert plate 3000 assembly station. On this basis, in this application, the valve body 2000 is placed horizontally on the conveying device 1, and the plug plate 3000 needs to be plugged into one side of the valve body 2000, and the valve body 2000 is directly moved above the first pushing device 23, that is, moved above the lifting device. The valve body 2000 and the plug plate 3000 below it are not aligned, so the picking device on the second movable component 221 is set to a swingable second picking component 222, so that after the second picking component 222 picks up the valve body 2000, it can swing along the horizontal axis to adjust the valve body 2000 to its side facing downward, so as to align with the plug plate 3000 below it, to achieve plug-in assembly, and then the second picking component 222 is swung back to the angle at which the valve body 2000 is placed on the conveying device 1, and the assembled valve body 2000 is placed back on the conveying device 1 to flow into the next process. It can be understood here that the swing angle of the second picking component 222 is not specifically limited, and is mainly determined by the pushing direction of the first pushing device 23 and the docking orientation of the valve body 2000 and the plug plate 3000, to ensure that the valve body 2000 can be aligned with the plug plate 3000, and the first pushing device 23 can push the plug plate 3000 to be plugged into the valve body 2000.

[0054] Specifically, the second pickup assembly 222 includes claws for clamping at both ends of the valve body 2000. The second pickup assembly 222 needs to bear the force of the first pushing device 23 pushing the insert plate 3000 until it is inserted into the valve body 2000. Therefore, the second pickup assembly 222 needs to lock the valve body 2000. Therefore, the present application configures the second pickup assembly 222 as the claw structure. To prevent the claw from interfering with the insertion of the insert plate 3000 and the valve body 2000, the claw avoids the side of the valve body 2000 and is clamped at both ends of the valve body 2000 to achieve the function of picking up the valve body 2000, thus meeting the functional requirements.

[0055] In addition, a pressure test station is provided between the loading station and the plugboard 3000 assembly station. A pressure test device 4 is installed at the pressure test station to perform a high-voltage resistance test on the valve body 2000. The automated assembly of the valve body 2000 requires automated testing, including a high-voltage resistance test on the valve body 2000 to ensure its electrical safety. Therefore, the solenoid valve assembly line 1000 is also equipped with the pressure test device 4. Specifically, the pressure test device 4 is provided between the loading station and the plugboard 3000 assembly station to complete the high-voltage resistance test on the valve body 2000 before the plugboard 3000 is assembled.

[0056] In addition, a continuity test station is provided between the plug board 3000 assembly station and the mounting board 4000 assembly station, and the continuity test station is provided with a continuity test device 5, and the continuity test device 5 includes a test probe 51 for extending into the plug board 3000; and / or, a visual inspection station is provided between the plug board 3000 assembly station and the mounting board 4000 assembly station, and the visual inspection station is provided with a second visual inspection device 6. After completing the assembly of the plug board 3000, it is understandable that it is necessary to judge the quality of the plug board 3000 after assembly to ensure the accuracy of the automated assembly and to ensure the stability of the automated assembly alignment. To this end, the present application proposes to set the conductivity test device 5 and the second visual inspection device 6 after the assembly station of the plug board 3000, and the test probe 51 of the conductivity test device 5 is extended into the plug board 3000 to perform a conductivity test. At the same time, the second visual inspection device 6 performs an appearance inspection on the assembly structure of the plug board 3000 inserted on the valve body 2000 to detect the accuracy of the plug-in alignment.

[0057] In addition, the mounting plate loading device 31 includes a feeding device 311 and a picking robot 312 arranged between the feeding device 311 and the second pushing device 33. Similar to the inserting plate loading device 21, the mounting plate loading device 31 is also set independently of the conveying device 1 to form an auxiliary material line to convey the mounting plate 4000 to the main line of the conveying device 1. It can be understood that the specific structure of the mounting plate loading device 31 can also be various, for example, it can be set to a vibration disk structure similar to the inserting plate loading device 21, based on the actual loading needs of the mounting plate 4000. In this application, the mounting plate 4000 has completed the surface coating process. If a vibration disk structure is used to vibrate and screen the mounting plate 4000, there will be collision and friction between the mounting plates 4000, which may affect the appearance of the mounting plate 4000 and lead to a problem of reduced yield. Therefore, this application does not screen the mounting plates 4000, that is, the disordered material bin described above is used, and the grasping robot automatically identifies, grasps and transports the mounting plates 4000.

[0058] Specifically, the feeding device 311 includes a material tray 3111, a third picking component 3112 and a feeding component 3113. The third picking component 3112 is used to pick up the installation plate 4000 in the material tray 3111 to the feeding component 3113, and the feeding component 3113 is used to transport the installation plate 4000 to the picking robot 312. It is understandable that the picking robot 312 can directly identify and pick up the mounting plates 4000 in the tray 3111. However, it is obvious that on the one hand, the number of mounting plates 4000 in the tray 3111 is too large, which increases the difficulty of identification. On the other hand, considering the space occupation problem, they cannot be freely arranged, which causes space occupation and waste. On the other hand, it is necessary to set the tray 3111 away from the main production device so that employees can replenish the mounting plates 4000 materials to the tray 3111 without stopping the production line during the production process. Therefore, the present application also proposes the third picking component 3112 and the feeding component 3113, and the third picking component 3112 picks up the mounting plates 4000 in the tray 3111 and sends them to the feeding component 3113. The feeding component 3113 then transports the mounting plates 4000 to the picking area of ​​the picking robot 312 for identification and picking by the picking robot 312, so as to solve the above problems.

[0059] Specifically, the third pickup component 3112 includes a magnetic component. The coating process on the surface of the mounting plate 4000 has been described above. If a rigid contact member is used to pick up the mounting plate 4000, the appearance of the mounting plate 4000 may be damaged. Therefore, this application sets the third pickup component 3112 to magnetic pickup, that is, the magnetic component is set on the third pickup component 3112 to utilize the ferromagnetism of the mounting plate 4000. The mounting plate 4000 can be picked up without rigid contact, thereby avoiding damage to the appearance of the mounting plate 4000 and improving the yield. Similarly, the method used by the picking robot 312 to pick up the mounting plate 4000 is also set to a magnetic method to obtain the same appearance protection effect.

[0060] In addition, the feeding assembly 3113 includes a vibration plate and / or a conveyor belt. The structure of the feeding assembly 3113 can be various, including a movable bearing structure, a conveyor belt, a vibration plate, etc., as long as it can realize the movement of the bearing mounting plate 4000. In the present application, the feeding assembly 3113 is segmented into the vibration plate and the transmission belt. On the one hand, the vibration plate vibrates slightly, and on the basis of ensuring the appearance of the mounting plate 4000, the overlapping mounting plates 4000 are separated, so that the mounting plates 4000 delivered to the conveyor belt are all in a dispersed independent state, further facilitating the picking robot 312 to identify and pick up.

[0061] In addition, the feeding device 311 also includes a return component 3114, and the return component 3114 is arranged between the discharge end of the feeding component 3113 and the material tray 3111, and is used to return the excess mounting plate 4000 to the material tray 3111. It can be understood that the feeding action of the feeding device 311 can be linked with the picking action of the picking robot 312, that is, after the picking robot 312 completes picking up the mounting plate 4000, the feeding device 311 moves again to transport the next batch of materials, thereby avoiding the situation where the picking robot 312 does not have time to pick up the mounting plate 4000 on the feeding device 311. However, this obviously increases the control cost and is unstable. In this application, the return component 314 is also provided in the feeding device 311. The material component 3114 does not require additional control, and the feeding device 311 can work continuously to ensure that the feeding component 3113 feeds the picking robot 312. At the same time, the mounting plate 4000 that is not picked up by the picking robot 312 in the future will also be returned to the material tray 3111 by the return component 3114, so as to be fed to the picking robot 312 again later. The control logic is simple and the cost is low, and the feeding device 311 only needs to be kept open, and the stability is strong.

[0062] Specifically, the return assembly 3114 includes a vibrating plate and / or a conveyor belt. Similar to the feed assembly 3113, the return assembly 3114 also utilizes the vibrating plate and the conveyor belt structure. However, the difference is that the feed assembly 3113 uses the vibrating plate to spread out the mounting plates 4000, making it easier for the picking robot 312 to identify and pick them up. The return assembly 3114 uses the vibrating plate simply because it requires less space than the conveyor belt and can be deployed in a smaller space, thus meeting the structural requirements of the solenoid valve assembly line 1000.

[0063] In addition, the second pushing device 33 includes a carrying fixture 331 that can be movably arranged between the picking robot 312 and the conveying device 1, and a pressing structure 332 that can be movably arranged above the carrying fixture 331. In order to allow the mounting plate loading device 31 to avoid the second transfer device 32 and the pressing structure 332 when loading the mounting plate 4000, the carrying fixture 331 is configured to be movable between the picking robot 312 and the conveying device 1. When the mounting plate 4000 is loaded, the carrying fixture 331 moves to a position corresponding to the picking robot 312 and away from the second transfer device 32 and the low-pressure structure, facilitating normal loading of the mounting plate 4000. After the mounting plate 4000 is loaded, the carrying fixture 331 moves to a position corresponding to the pressing structure 332 to be used for pressing and clamping the mounting plate 4000 and the valve body 2000 in the subsequent process. It can be understood that the carrying tooling 331 carries the mounting plate 4000. Therefore, in order to facilitate the valve body 2000 to be clamped on the mounting plate 4000, the picking robot 312 needs to adjust the mounting plate 4000 so that its notch is facing upward and then place it on the carrying tooling 331, so that the valve body 2000 can be placed in the notch of the mounting plate 4000 from top to bottom, and finally the pressing structure 332 presses to complete the clamping of the valve body 2000 and the mounting plate 4000, thereby completing the assembly process of the valve body 2000 and the mounting plate 4000.

[0064] Specifically, a detachable pressing member 3321 is provided at the lower end of the pressing structure 332. The clamping angles between different valve bodies 2000 and different mounting plates 4000 may vary, resulting in different pressing positions of the pressing structure 332. Therefore, to ensure the versatility of the pressing structure 332, a detachable pressing member 3321 is provided at the lower end of the pressing structure 332. This allows for quick replacement of the corresponding pressing member 3321 during assembly of each valve body 2000 and mounting plate 4000 combination, thus satisfying universal usage requirements.

[0065] In addition, the second transfer device 32 includes a third movable component 321 that can be movably set and a fourth picking component 322 that is rotatably set on the third movable component 321 along the horizontal axis. The fourth picking component 322 is used to rotate and adjust the assembly angle between the valve body 2000 and the mounting plate 4000. The clamping angles between different valve bodies 2000 and different mounting plates 4000 may be different, as described above, and the horizontal placement of the valve body 2000 on the conveying device 1 has also been described above. Therefore, the angle between the horizontally placed valve body 2000 and the mounting plate 4000 with the notch facing upward placed on the second push device 33 is a fixed value. In order to meet the different installation angles, the second transfer device 32 has, in addition to the third movable component 321 that can move in three-dimensional space, the fourth picking component 322 that can be rotatably arranged on the third movable component 321. The third movable component 321 can transfer the valve body 2000 from the assembly station of the mounting plate 4000 to the corresponding second push device 33. The fourth picking component 322 is used to pick up the valve body 2000, and after picking up the valve body 2000, it rotates around the axis of the pipe mouth of the clamping mounting plate 4000 to adjust the installation angle of the valve body 2000 relative to the mounting plate 4000 to meet functional requirements.

[0066] Specifically, the rotation angle of the fourth pickup assembly 322 is adjustable. In conjunction with the switching function of the pressing member 3321, the rotation angle of the fourth pickup assembly 322 is adjustable, allowing for rapid switching between different valve bodies 2000 and mounting plate 4000 assemblies during production, thereby meeting the need for rapid product switching on the solenoid valve assembly line 1000.

[0067] In addition, a labeling station is provided between the assembly station of the mounting plate 4000 and the blanking station. A labeling device 7 is provided at the labeling station. The labeling device 7 includes a label feeding device 71 and a labeling assembly 72. The labeling assembly 72 is used to pick up the label at the label feeding device 71 and attach it to the surface of the valve body 2000. When the plug-in plate assembly device 2 and the mounting plate assembly device 3 complete the assembly of the valve body 2000, the plug-in plate 3000 and the mounting plate 4000 to form the required solenoid valve product, it is generally necessary to attach a product label or a certificate of conformity to the surface of the product. Therefore, the present application also provides the labeling station between the assembly station of the mounting plate 4000 and the blanking station, and provides the labeling device 7 at the labeling station, so that the automatic labeling of the solenoid valve product can be completed by the labeling device 7, thereby further improving the degree of automation of the solenoid valve assembly line 1000. Specifically, the labeling equipment 7 includes the label delivery device 71 and the labeling component 72. The label delivery device 71 is similar to the insert plate loading device 21 and the installation plate loading device 31. They are all auxiliary material conveying structures independent of the conveying device 1. The specific structure is not limited in this application. It can deliver product labels to the labeling station, and the labeling component 72 can pick them up and attach them to the solenoid valve product.

[0068] Specifically, the labeling assembly 72 includes a turntable 721 and a material picking rod 722 extending radially along the turntable 721 . In this application, the product label is mainly attached to the side of the horizontally placed valve body 2000, so the labeling component 72 needs to pick up the product label, rotate the label to the side corresponding to the valve body 2000, and attach it close to the valve body 2000. Therefore, this application proposes that the labeling component 72 includes the turntable 721 and the material picking rod 722. The material picking rod 722 extends in the horizontal direction when picking up the material, and its lower end can approach and pick up the horizontally unfolded label delivered by the label feeding device 71. Then the turntable 721 rotates, driving the material picking rod 722 to rotate, so that the material picking rod 722 rotates to extend in the up and down direction. At this time, the label picked up by the material picking rod 722 completes a certain angle rotation, and then approaches the label attachment surface of the valve body 2000. During the rotation of the turntable 721, the material picking rod 722 attaches the label to the valve body 2000, completing the label attachment action and meeting the functional requirements.

[0069] Specifically, a second vacuum adsorption assembly is provided at the end of the picking rod 722. There are various ways for the end of the picking rod 722 to pick up labels, including a pasting structure, a clamping structure, a vacuum adsorption structure, etc. This application mainly uses the second vacuum adsorption assembly for vacuum adsorption, which is convenient, fast, and will not damage the label.

[0070] In addition, the turntable 721 is further provided with a pressure rod 723 extending along its radial direction, and the pressure rod 723 is arranged at a certain angle to the picking rod 722. The label attached to the surface of the valve body 2000 by the picking rod 722 may not be firmly adhered and may fall off. Therefore, the present application further provides the pressure rod 723 on the turntable 721, and the pressure rod 723 is arranged at a certain angle to the picking rod 722. In this way, when the picking rod 722 is picking up the label, the pressure rod 723 corresponds to the label attached to the side of the valve body 2000. At this time, the labeling assembly 72 moves downward as a whole, that is, the turntable 721 drives the picking rod 722 to move down close to the label for picking up, and the turntable 721 drives the pressure rod 723 to move downward. The pressure rod 723 can abut against the label on the side of the valve body 2000 and compact the label from top to bottom, thus avoiding the above-mentioned problem of weak adhesion. Here, the pressure rod 723 and the material picking rod 722 are driven by the movement of the turntable 721 to move synchronously to synchronously realize two actions, namely, label picking and label compacting. Compared with setting the pressure rod 723 independently from the turntable 721 to independently control the label compacting action, the linkage action adopted in this application is more ingenious, with a simple structure and good effect. After the label is attached to the label holder 2000, the rotating disk 721 moves upward and rotates until the picking rod 722 extends horizontally, and the pressure rod 723 rotates to the label-sticking surface corresponding to the valve body 2000. Then the rotating disk 721 moves downward to make the picking rod 722 pick up the label, and the pressure rod 723 completes the compaction of the label. After the action is completed, the rotating disk 721 moves upward again, driving the pressure rod 723 to separate from the valve body 2000 and driving the picking rod 722 to remove the label. At this time, the valve body 2000 completes the labeling, and the conveying device 1 conveys the upstream valve body 2000 without a label to the labeling component 72. The rotating disk 721 rotates again to drive the picking rod 722 to attach the label to the side of the valve body 2000. This is repeated to achieve a stable labeling action of the valve body 2000. It should be noted here that the distance between the end of the material picking rod 722 and the rotation center of the turntable 721 is greater than the distance between the end of the pressure rod 723 and the rotation center of the turntable 721. On the one hand, the label delivery device 71 can be set away from the conveying device 1 to avoid interference. On the other hand, when the turntable 721 rotates so that the material picking rod 722 drives the label to be attached to the valve body 2000, the pressure rod 723 will not contact the valve body 2000, thereby avoiding conflicts between the pressure rod 723 driven to rotate synchronously by the turntable 721 and the material picking rod 722 when performing their own functions, thereby meeting structural and functional requirements.

[0071] Specifically, the end of the pressure rod 723 is provided with a roller 7231. The end of the pressure rod 723 can be configured as an elastic member to prevent the pressure rod 723 from rigidly contacting the label on the valve body 2000, which could damage the label. However, during the downward movement of the pressure rod 723, there is still sliding friction between the pressure rod 723 and the label, which may cause the label to become dirty and damaged during long-term use. Therefore, in this application, the roller 7231 is also provided at the end of the pressure rod 723. The roller 7231 is held against the surface of the label, and during the downward movement of the pressure rod 723, the roller 7231 rolls along the surface of the label to compact the label, thereby avoiding the above-mentioned problem and meeting the requirements.

[0072] In addition, a color detection station is provided between the labeling station and the blanking station. A color detection device 8 is provided at the color detection station to detect the color of the label. The solenoid valve assembly line 1000 can be used to assemble a variety of valve bodies 2000, corresponding to different types of labels. Therefore, the present application also provides the color detection station between the labeling station and the blanking station to detect the label attached to the valve body 2000, ensuring accuracy and preventing incorrect label types from being posted.

[0073] In addition, a fourth transfer device 9 is provided at the loading station, and is used to transfer the valve body 2000 from the preceding process to the conveying device 1. The conveying device 1 on the solenoid valve assembly line 1000 is independent of the preceding process. On the one hand, this shortens the conveying device 1, facilitating low maintenance costs. On the other hand, considering that the valve body 2000 circulating in the preceding process and the valve body 2000 of the solenoid valve assembly line 1000 have different orientations, when the fourth transfer device 9 transfers the valve body 2000 from the preceding process to the conveying device 1, it simultaneously adjusts the valve body 2000 circulating in the preceding process to the required orientation of the valve body 2000 at the loading station to meet the requirements of subsequent assembly steps.

[0074] In addition, the unloading station is provided with a waste recovery device 10 and an output device 11. The above describes a variety of devices for detecting the valve body 2000 and the valve body 2000 assembly, including the pressure test device 4, the first visual inspection device 2111, the second visual inspection device 6, the conduction test device 5, and the color detection device 8. In the automated production process, it is possible that any of the above detection devices fails to meet the inspection requirements. It is cumbersome to set up an independent recovery device downstream of each detection device. Therefore, in this application, the waste recovery device 10 is provided at the unloading station. The valve body 2000 detected to have abnormalities at the above detection devices is normally transferred by the conveying device 1 to the unloading station for waste recovery processing, thereby simplifying the setting of the waste recovery device 10.

[0075] Specifically, the waste recycling device 10 includes a waste recycling conveyor belt 101. To avoid affecting the normal operation of the solenoid valve assembly line 1000, the waste recycling device 10 includes the waste recycling conveyor belt 101 to transport the waste to a portion away from the main body of the solenoid valve assembly line 1000. This prevents employees from affecting the continuous production of the solenoid valve assembly line 1000 when removing the waste, thereby ensuring the automated production efficiency of the solenoid valve assembly line 1000.

[0076] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
