Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In the diagram, units with similar structures are represented by the same labels.

[0053] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0054] The following is a preferred embodiment of a compact faucet assembly and testing line provided by the present invention, which can solve the above-mentioned technical problems.

[0055] A preferred embodiment of the compact faucet assembly and testing line provided by the present invention is as follows: The compact faucet assembly and testing line includes a first processing unit 1 and a second processing unit 2. The faucet includes a sealing ring, a spout, a valve body, a valve core, a handle, and a pressure cap. The first processing unit 1 is used to assemble the sealing ring and spout of the faucet, as well as the spout and valve body. The second processing unit 2 is located on one side of the first processing unit 1 and is used to assemble the valve core and valve body, the handle and valve core, and the handle and pressure cap of the faucet, and to test the quality of the faucet.

[0056] The first processing unit 1 includes: a sealing ring conveying mechanism 11 for conveying sealing rings, a water outlet conveying mechanism 12 for conveying water outlets, a valve body conveying mechanism 13 for conveying valve bodies, and a first assembly mechanism 14 for assembling sealing rings and water outlets, as well as assembling water outlets and valve bodies. The sealing ring conveying mechanism 11, the water outlet conveying mechanism 12, and the valve body conveying mechanism 13 are respectively arranged around the periphery of the first assembly mechanism 14.

[0057] The second processing unit 2 includes: a valve core processing mechanism 21, a handle processing mechanism 22, a faucet testing mechanism 23, a cap processing mechanism 24, and a water conveying mechanism 25. The valve core processing mechanism 21 is located at one end of the handle processing mechanism 22 and is connected to the handle processing mechanism 22 through the water conveying mechanism 25. It is used to assemble the valve core and the valve body together. The other end of the handle processing mechanism 22 is connected to the faucet testing machine through the water conveying mechanism 22. It is used to assemble the valve body and the handle together. The cap processing mechanism 24 is located on one side of the faucet testing mechanism 23 and is connected to the water conveying mechanism 22. It is used to assemble the faucet and the cap together. The water conveying mechanism 25 is used to convey the semi-finished faucet products input from the valve core processing mechanism 21, the handle processing mechanism 22, and the faucet testing mechanism 23 to the cap processing mechanism 24.

[0058] The compact faucet assembly and testing line of the present invention completes the processing of faucets by setting up a first processing unit and a second processing unit to replace manual assembly. It is easy to operate, simple in steps, and highly efficient, and can keep up with market supply demand. It solves the problems of high difficulty, cumbersome steps and low efficiency of manual faucet assembly in the prior art.

[0059] Please combine Figure 1 , Figure 2 The first processing unit 1 of the present invention will be described in detail below:

[0060] Traditional production lines often have devices arranged linearly, one after another, which looks like a long line. However, this invention arranges the devices together, making the processing more compact, the production efficiency higher, and reducing unnecessary transport links.

[0061] Please combine Figure 3 , Figure 4 The sealing ring conveying mechanism 11 of the present invention will be described in detail below:

[0062] Considering that the sealing rings are lightweight and made of soft, easily deformable material, they are prone to flying out during transport on the conveyor belt via vibration. Therefore, the sealing ring conveying mechanism 11 includes: a sealing ring vibratory feeder 111, a sealing ring conveyor belt 112, and a sealing ring robot 113. The sealing ring vibratory feeder 111 is connected to one end of the sealing ring conveyor belt 112, and one end of the sealing ring conveyor belt 112 is located on one side of the first assembly mechanism 14. The sealing ring robot 113 is located on one side of the sealing ring conveyor belt 112. The sealing ring conveyor belt 112 includes a first limiting block 1121, which is located above the sealing ring conveyor belt 112, connected to the side wall of the sealing ring conveyor belt 112, and extends above the conveying surface of the sealing ring conveyor belt 112. The first limiting block 1121 blocks the space above the sealing ring conveyor belt 112, preventing the sealing rings from vibrating out of the sealing ring conveyor belt 112 during vibration, thus improving work efficiency.

[0063] During the vibration of the sealing ring vibratory plate 111, the sealing ring conveyor belt 112 is often subjected to certain follow-up movements. In severe cases, the sealing ring conveyor belt 112 may be damaged, resulting in leakage of the sealing ring and affecting the conveying efficiency. Therefore, the sealing ring conveying mechanism 11 also includes a conveyor belt support 114. The conveyor belt support 114 is located below the sealing ring conveyor belt 112 and is used to support the sealing ring conveyor belt 112. Setting the conveyor belt support 114 can greatly improve the stability of the sealing ring conveyor belt 112.

[0064] To further improve the stability of the sealing ring vibratory feeder 111 and enable the sealing ring to be conveyed more stably on the sealing ring conveyor belt 112, the conveying surface of the sealing ring conveyor belt 112 is mountain-shaped, and a protrusion 1123 is provided in the middle of the sealing ring conveyor belt 112. The height of the protrusion 1123 is flush with the surface height of the sealing ring connecting belt. The mountain shape is designed to raise the middle of the sealing ring conveyor belt 112, reducing the contact area between the sealing ring and the sealing ring conveyor belt 112. This allows the abnormal sealing ring, i.e., the twisted sealing ring, to be vibrated into a normal shape by the protrusion 1123. At the same time, raising the bottom surface of the sealing ring conveyor belt 112 further compresses the space in which the sealing ring can vibrate up and down, thereby improving the stability of the sealing ring conveying mechanism 11.

[0065] Considering that installing the first limiting blocks 1121 on the entire top surface of the sealing ring conveyor belt 112 would consume a lot of material, the sealing ring conveyor belt 112 also includes limiting rods 1122. The first limiting blocks 1121 have second connecting grooves, and the limiting rods 1122 are fixed in the second connecting grooves, located above the protrusions 1123. In this way, only two first limiting blocks 1121 are needed, and the limiting rods 1122 are sufficient to limit the vibration space of the sealing ring, resulting in high cost-effectiveness.

[0066] Please combine Figure 5 The structure of the second limiting block of the present invention will be described in detail below:

[0067] To facilitate the unloading of the sealing rings, the sealing ring conveying mechanism 11 also includes a second limiting block. The second limiting block is connected to the other end of the sealing ring conveyor belt 112. The second limiting block is provided with a limiting groove 1151, which is connected to the other end of the sealing ring conveyor belt 112. Under the drive of the sealing ring vibrating plate 111 and the sealing ring conveyor belt 112, the sealing rings come to the second limiting block. The subsequent sealing rings will no longer push the sealing rings located on the second limiting block forward. At the same time, the second limiting block provides a space for the sealing ring robot 113 to unload the sealing rings, which is highly practical.

[0068] When the vibrating disc 111 vibrates too violently, causing the sealing ring to move too fast on the conveyor belt 112, the sealing ring may collide with the second limiting block and fly out. Therefore, the end of the limiting groove 1151 away from the conveyor belt 112 is a circular groove. The circular groove can increase the contact area between the sealing ring and the limiting groove 1151, effectively reducing the impact of the sealing ring on the second limiting block, and avoiding the problem of the sealing ring flying out of the second limiting block when the vibrating disc 111 vibrates too violently and moves too fast on the conveyor belt 112.

[0069] Please combine Figure 3The structure of the sealing ring robot 113 of the present invention will be described in detail below:

[0070] In this invention, the sealing ring robot 113 includes a gripper 1131 and a push-pull member 1132. The push-pull member 1132 is located above the gripper 1131. The bottom diameter of the gripper 1131 is smaller than the top diameter of the gripper 1131. The inner diameter of the sealing ring is between the bottom diameter and the top diameter of the gripper 1131. That is, the gripper 1131 gradually increases in size from the bottom to the top in a bullet shape, so that the sealing ring can be easily inserted into the gripper 1131 to achieve gripping.

[0071] To ensure a high success rate of grasping, the second limiting block also includes a pressing groove 1152. The movement trajectory of the robotic arm includes a loading position. When the robotic arm is in the loading position, it is positioned above the pressing groove 1152. It should be noted that a flexible material, such as sponge, is placed inside the pressing groove 1152. This flexible material deforms under pressure and recovers its elastic deformation when the pressure is released. When no force is applied, the height of this flexible material is flush with the height of the limiting groove 1151. When the gripper 1131 grasps the sealing ring downwards, the bottom end of the gripper 1131 can extend into the pressing groove 1152, ensuring that the sealing ring can fully engage with the gripper 1131, thus guaranteeing a high success rate of grasping.

[0072] In order to ensure that the push-pull component 1132 can be tightly connected with the gripper 1131 and to ensure that the gripper 1131 can perform normal loading and unloading operations, the sealing ring robot 113 also includes a horizontal cylinder 1133. The horizontal cylinder 1133 is connected to the push-pull component 1132 and is used to drive the push-pull component 1132 to move horizontally. The push-pull component 1132 has a T-shaped structure. The top of the gripper 1131 is provided with a push-pull groove that matches the push-pull component 1132. The T-shaped push-pull component 1132 can be well engaged in the push-pull groove, improving the stability of the structure.

[0073] To prevent the sealing ring robot 113 from damaging the second limiting block during the sealing ring feeding process, the second limiting block also includes a pad 1153. The pad 1153 is located above the second limiting block and is detachably connected to the second limiting block. It is understood that the pad 1153 is also made of flexible material.

[0074] Please combine Figure 6 The water outlet conveying mechanism 12 of the present invention will be described in detail below:

[0075] The spout conveying mechanism 12 includes: a spout vibratory plate 121, a spout conveyor belt 122, and a spout robot 123. The spout vibratory plate 121 is connected to one end of the spout conveyor belt 122, one end of the spout conveyor belt 122 is located on one side of the first assembly mechanism 14, and the spout robot 123 is located on one side of the spout conveyor belt 122.

[0076] The water outlet conveyor belt 122 has a limiting shell 1221 on its outer side to limit the position of the water outlet on the conveyor belt 122. The limiting shell 1221 has a T-shaped opening, which matches the shape of the water outlet and prevents the water outlet from tipping over on the conveyor belt 122, thus improving conveying efficiency. In addition, a viewing window is provided above the limiting shell 1221, which allows workers to monitor the conveying status of the water outlet.

[0077] Please combine Figure 7 , Figure 8 , Figure 9 The valve body conveying mechanism 13 of the present invention will be described in detail below:

[0078] The valve body conveying mechanism 13 includes: a valve body vibratory plate 131, a valve body conveyor belt 132, and a valve body manipulator. The valve body vibratory plate 131 is connected to one end of the valve body conveyor belt 132, one end of the valve body conveyor belt 132 is located on one side of the first assembly mechanism 14, and the valve body manipulator is located on one side of the valve body conveyor belt 132.

[0079] Unlike traditional conveyor belts, the valve body conveyor belt 132 includes a vibrating plate 1321, a vibrating support 1322, a vibrating rod 1323, and a vibrating block 1324. The vibrating support 1322 is located on the vibrating plate 1321 and has a first connecting groove. The vibrating rod 1323 is located in the first connecting groove and is used to limit the movement of the valve body. The vibrating block 1324 is located on the vibrating support 1322 and is used to support the valve body. The vibrating support 1322 is a square sheet structure with an opening at one corner and a hollow interior, used to place and vibrate the valve body. The valve body includes an inlet, an outlet, and a valve port. The vibrating rods 1323 include supporting vibrating rods and limiting vibrating rods. The supporting vibrating rods are triangularly distributed to support the outlet, which is located between them. The limiting vibrating rods are positioned above the valve port to limit the valve body's position and prevent it from tipping over during vibration. Vibrating blocks 1324 are located on the vibrating support 1322 and support the inlet. Multiple sets of vibrating supports 1322 are evenly distributed on the valve body conveyor belt 132. The valve body conveyor belt 132 uses the vibrating plate 1321, vibrating supports 1322, vibrating rods 1323, and vibrating blocks 1324 to position and transport the valve body, ensuring it does not tip over.

[0080] In this invention, the vibrating block 1324 includes a connecting part 1324a and a supporting part 1324b. The connecting part 1324a is provided with a first connecting hole, and the vibrating bracket 1322 is provided with a second connecting hole corresponding to the first connecting hole. The vibrating block 1324 and the vibrating bracket 1322 are detachably connected through the first connecting hole and the second connecting hole. Different models of vibrating blocks 1324 can be replaced according to different models of valve bodies, which improves applicability.

[0081] Because the valve body has a rigid structure and a large mass, the vibrating block 1324 also includes a reinforcing part 1324c. One end of the reinforcing part 1324c is connected to the connecting part 1324a, and the other side is connected to the bearing part 1324b. The reinforcing part 1324c is perpendicular to the bearing part 1324b, which makes the structure of the vibrating block 1324 more stable.

[0082] In addition, the valve body conveyor belt 132 also includes a stop block located at one end of the valve body conveyor belt 132 away from the valve body vibrating plate 131, which is used to limit the valve body from continuing to move so that the valve body robot can perform the unloading operation of the valve body.

[0083] In order to enable the valve body robot to grasp more accurately, the valve body conveyor belt 132 also includes a limiting rod 1122. The limiting rod 1122 is located at the end of the valve body conveyor belt 132 away from the vibratory plate, and is used to limit the valve body to ensure that the valve body is in a vertical state, so as to facilitate the valve body robot to unload it.

[0084] Considering the rigid structure and large mass of the valve body, which would generate significant noise during transport on the valve body vibratory plate 131, the valve body input device also includes a soundproof housing. This housing is located on the outside of the valve body vibratory plate 131 and features a sliding door and an opening through which the conveyor belt passes. Utilizing the principle of gradually varying acoustic impedance, the inner wall of the soundproof housing has conical blocks, further reducing the noise generated during the valve body's transport on the valve body vibratory plate 131.

[0085] Please combine Figure 10 The first assembly mechanism 14 of the present invention will be described in detail below:

[0086] The first assembly mechanism 14 includes: a first assembly frame 141, a first tray 142, a second tray 143, a first clamping member 144, a rotating member 145, and a first assembly conveyor belt 146. The first tray 142 is connected to the first assembly frame 141, and the second tray 143 is also connected to the first assembly frame 141. The first tray 142 is located above the second tray 143, and the diameter of the first tray 142 is smaller than the diameter of the second tray 143. The first clamping member 144 is located on and connected to the first tray 142. The rotating member 145 passes around the second tray 143 in a circular array. The first assembly conveyor belt 146 is located on one side of the first tray 142 and connected to the first assembly frame 141, used to transport the faucets processed by the first processing unit 1. The rotation of the first tray 142 and the second tray 143 drives the movement of the water spout, replacing some of the functions of the robotic arm and making the entire mechanism structure more compact.

[0087] In addition, the first assembly mechanism 14 also includes a first rotating shaft, a second rotating shaft, and two drive devices 214. One end of the first rotating shaft is connected to the first disc 142, and the other end is connected to the first assembly frame 141. One end of the second rotating shaft is connected to the second disc 143, and the other end is connected to the first assembly frame 141. Both drive devices 214 are connected to the first assembly frame 141 and are used to drive the first disc 142 and the second disc 143 to rotate. The first clamping member 144 on the first disc 142 holds the water outlet and, in conjunction with the valve body manipulator, aligns the water outlet with the valve body. The rotating member 145 on the second disc 143 drives the water outlet to rotate, completing the assembly of the water outlet and the valve body. The use of drive devices 214 makes the entire mechanism more automated and improves production efficiency.

[0088] Please combine Figure 1 , Figure 11 The second processing unit 2 of the present invention will be described in detail below:

[0089] The second processing unit 2 of the present invention inspects the quality of the faucet before it is largely assembled, and classifies and processes unqualified faucets. This reduces the use of materials and avoids discovering that the faucet is unqualified only after it is fully assembled. Compared with the traditional method of assembling first and then inspecting, the second processing unit 2 of the present invention saves more materials.

[0090] Please combine Figure 12 , Figure 13 The valve core processing mechanism 21 of the present invention will be described in detail below:

[0091] The valve core processing mechanism 21 includes a machine frame 211 and a conveying device. The machine frame 211 has protruding ribs. The conveying device is located inside the machine frame 211 and is slidably connected to it. The conveying device includes a slider, a support plate, and a tray. The slider has grooves corresponding to the protruding ribs, and the slider is slidably connected to the machine frame 211. The support plate is located on the slider and is detachably connected to it, used to support the tray. The tray is located on the support plate and is detachably connected to it. The conveying device includes a first conveying device 212 and a second conveying device 213, with the first conveying device 212 located above the second conveying device 213. The first conveying device 212 includes a first tray 2121, and the second conveying device 213 includes a second tray 2131 and a lifting assembly 2132. The lifting assembly 2132 is used to lift the second pallet 2131. The movement trajectory of the first pallet 2121 includes a first loading position and a first unloading position, and the movement trajectory of the second pallet 2131 includes a second loading position and a second unloading position. The first loading position is located above the second loading position, and the first unloading position is located above the second unloading position. When the first pallet 2121 is at the first loading position, the second pallet 2131 is at the second unloading position; when the first pallet 2121 is at the first unloading position, the second pallet 2131 is at the second loading position.

[0092] Since it is difficult to fix the tray containing the valve core on the slider, the tray is used as a support surface. In order to ensure the normal operation of the equipment, the tray needs to be firmly connected to the tray. Therefore, the tray includes mounting posts, and the tray has mounting holes corresponding to the support posts. The tray and the tray are detachably connected through the mounting posts and mounting holes. This method is not only firm, but also easy to disassemble and assemble. For packing operations, changing the tray is simple.

[0093] Considering that the valve core processing mechanism 21 needs to move the transport device back and forth at a high frequency, while setting a single-sided slide rail can meet the requirements, it may pose a risk of structural loosening. Therefore, the equipment frame 211 includes a first wall and a second wall, and the protrusion includes a first protrusion and a second protrusion. The first protrusion is located on the first wall, and the second protrusion is located on the second wall. Protrusions are set on both inner walls of the equipment frame 211 to make the structure more stable.

[0094] To further automate the process, the valve core machining mechanism 21 also includes a drive unit 214, which comprises a transmission wheel 2141, a follower wheel 2142, a conveyor belt 2141, and a drive motor. The transmission wheel 2141 is located inside the equipment frame 211 and connected to the drive motor. The follower wheel 2142 is located inside the equipment frame 211 and connected to it. The conveyor belt 2141 is fitted over the transmission wheel 2141 and the follower wheel 2142. The drive motor is located outside the equipment frame 211 and connected to the transmission wheel 2141, driving its rotation. The introduction of the drive unit 214 further reduces the workload of workers while improving production efficiency.

[0095] Since mechanical transmission cannot be stopped and started as quickly as manual transmission, the conveying device also includes a stop block. The stop block is located on one side of the convex strip and is connected to the equipment frame 211. The stop block is set on one side of the convex strip to limit the slider and prevent the slider from rushing out of the convex strip. It is understood that the stop block is made of flexible material, which can reduce the impact when the slider collides with the stop block and protect the normal operation of the overall structure.

[0096] To save the height occupied by the valve core input device and to enable the first conveying device 212 to move synchronously with the second conveying device 213, the second conveying device 213 includes a first support plate 2133, a second support plate 2134, and a second slider. The first support plate 2133 is located between the second support plate 2134 and the second tray 2131 to support the second tray 2131. The second support plate 2134 is connected to the second slider. The top end of the second slider is connected to the conveyor belt 2141, and the bottom end of the first slider is connected to the conveyor belt 2141. The two sliders are connected to the same conveyor belt 2141, which can save the space of a conveyor belt 2141 and a synchronization device.

[0097] Since the second conveying device 213 is located below the first conveying device 212, and the second unloading position is located below the first unloading position, the lifting assembly 2132 is required to lift the second pallet 2131 from the second unloading position to the first unloading position for unloading operation. If the pallet is lifted directly, it will be difficult to fix the pallet. If the pallet is to be fixed, it must be connected to the lifting assembly 2132, which makes it inconvenient to disassemble and assemble the pallet, thus affecting the filling efficiency. Therefore, the first pallet 2133 of the second conveying device 213 plays such a connecting role, supporting the second pallet 2131 for placing the valve core above and the second pallet 2134 for connecting the second slider below. The lifting assembly 2132 is located between the second pallet 2134 and the first pallet 2133.

[0098] Please combine Figure 14 The lifting device structure of the present invention will be described in detail below:

[0099] Considering that the lifting assembly 2132 is installed on the second support plate 2134 to support the first support plate 2133, wear is inevitable at the connection between the first support plate 2133 and the lifting assembly 2132. Therefore, in addition to the lifting rod 2132c, the lifting assembly 2132 also includes a protective sleeve 2132a and a buffer block 2132b. The protective sleeve 2132a is located outside the lifting rod 2132c and is connected to the second support plate 2134. The buffer block 2132b is located above the protective sleeve 2132a, near one end of the first support plate 2133, and is connected to the first support plate 2133. The protective sleeve 2132a and the buffer block 2132b effectively reduce the impact between the lifting assembly 2132 and the first support plate 2133, and can protect the lifting assembly 2132 and the first support plate 2133.

[0100] In order to ensure that the slider can be stably driven by the conveyor belt 2141, the slider is provided with a groove, and the conveyor belt 2141 is located in the groove, which increases the contact area between the conveyor belt 2141 and the slider, increases the friction, and enables the slider to be driven by the conveyor belt 2141. At the same time, the slider and the conveyor belt 2141 can be easily disassembled, and it is very convenient to replace the conveyor belt 2141 if it is damaged.

[0101] In addition, the conveying device also includes a trough cover, which is located above the belt trough and is detachably connected to the belt trough. Covering the belt trough with the trough cover further increases the contact area between the conveyor belt 2141 and the slider, ensuring that the conveyor belt 2141 can stably drive the slider to move.

[0102] Please combine Figure 15 , Figure 16 , Figure 17 , Figure 18 The handle processing mechanism 22 of the present invention will be described in detail below:

[0103] The handle processing mechanism 22 includes a handle conveying device 221, a screw conveying device 222, and a handle assembly device 223. The handle conveying device 221 is located at one end of the handle assembly device 223, and the screw conveying device 222 is located at the other end of the handle assembly device 223.

[0104] Unlike traditional conveying devices, the handle conveying device 221 includes a handle vibratory plate 2211, a handle conveyor belt 2212, and a handle manipulator 2213. The handle vibratory plate 2211 is connected to one end of the handle conveyor belt 2212, and the handle manipulator 2213 is located on one side of the handle conveyor belt 2212. The handle conveyor belt 2212 includes a handle vibrating plate 2212a, a handle vibrating bracket 2212b, and a handle vibrating rod 2212c. The handle vibrating bracket 2212b is located on the handle vibrating plate 2212a and has a first groove. The handle vibrating rod 2212c is located in the first groove and is used to limit and support the handle. The handle conveyor belt 2212 uses the handle vibrating plate 2212a, the handle vibrating bracket 2212b, and the handle vibrating rod 2212c to position and convey the handle, while ensuring that the handle does not tip over.

[0105] The handle manipulator 2213 includes a handle gripper 2213a, a rotating shaft 2213c, a vibrating element 2213b, and a driver. The handle gripper 2213a is located below the vibrating element 2213b and is used to grip the handle. The rotating shaft 2213c passes through the vibrating element 2213b and is connected to the vibrating element 2213b. The driver is located above the rotating shaft and includes a rotating shaft 2213da, a connecting member 2213db, a drive gear 2213dc, and a drive member 2213dd. The drive member 2213dd is connected to the rotating shaft 2213da. The rotating shaft 2213da is connected to the drive gear 2213dc through the connecting member 2213db. The rotating gear 2213dc is connected to the rotating shaft 2213c and is used to drive the rotating shaft 2213c to rotate. The drive component 2213dd drives the rotating shaft 2213da to rotate. The rotating shaft 2213da drives the drive gear 2213dc to reciprocate. The drive gear 2213dc drives the rotating shaft 2213c to move radially around the rotating shaft 2213c. When the operating frequency of the drive component 2213dc increases, a visual effect of vibration of the vibrating component 2213b is generated, which helps to connect the valve core and the handle. Since the connection between the valve core and the handle is toothed, the teeth need to mesh to complete the installation. Therefore, in order to avoid the misalignment between the teeth of the handle and the teeth of the valve core, making it difficult to mesh, the vibrating component 2213b of the handle manipulator 2213 can easily mesh the handle gripper 2213a with the valve core through slight vibration, thereby improving the accuracy and efficiency of production.

[0106] Please combine Figure 19 The faucet testing mechanism 23 of the present invention will be described in detail below:

[0107] The pre-processed faucet is transported to the faucet testing mechanism 23 via the water conveyor mechanism 25 for testing. The faucet testing mechanism 23 includes a quality testing mechanism 231, an airtightness testing mechanism 232, and a first testing robot 233. The quality testing mechanism 231 is located at one end of the airtightness testing mechanism 232, and the first testing robot 233 is located on one side of the quality testing mechanism 231 and the airtightness testing mechanism 232, and is used to grab the faucet to be tested.

[0108] In this invention, the faucet testing mechanism 23 includes two main testing mechanisms, each corresponding to different tests. First, a quality test is performed to ensure the faucet meets quality standards. Qualified faucets are picked up by the first testing robot 233 and transferred to the airtightness testing mechanism 232 for further airtightness testing. Unqualified faucets are placed in the defective product hopper 2311 located in the quality testing mechanism 231. Next, an airtightness test is performed. Qualified faucets can proceed to subsequent processing, ensuring that their airtightness also meets standards. The quality testing mechanism 231 includes four detection slots 2321, which perform tests simultaneously, greatly increasing testing efficiency. After a series of tests, situations where only the quality is qualified but the airtightness is unqualified, or vice versa, are avoided, thus improving the quality of the faucets.

[0109] Please combine Figure 20 The capping mechanism 24 of the present invention will be described in detail below:

[0110] The capping processing mechanism 24 includes: a capping vibratory feeder 241, a capping conveyor belt 242, a capping robot 243, and an assembly tray 244. The capping vibratory feeder 241 is connected to one end of the capping conveyor belt 242, the capping robot 243 is located on one side of the capping conveyor belt 242, and the assembly tray 244 is connected to the other end of the capping conveyor belt 242. The capping conveyor belt 242 includes a capping limiting block 2421, which is located above the capping conveyor belt 242, connected to the side wall of the capping conveyor belt 242, and extends above the conveying surface of the capping conveyor belt 242. Using the capping limiting block 2421 effectively ensures that the caps will not be vibrated off the conveyor belt during transmission, improving transmission efficiency.

[0111] To further improve the stability of the capping vibratory feeder 241 and enable more stable capping conveyor belt 242, a second groove is provided in the middle of the capping conveyor belt 242. Considering that installing capping limiting blocks 2421 on the entire top surface of the conveyor belt would consume a large amount of material, the capping conveyor belt 242 also includes a capping limiting rod 1122. A third groove is provided on the capping limiting block 2421, and the capping limiting rod 1122 is fixed in the third groove, located above the capping conveyor belt 242. In this way, only two capping limiting blocks 2421 are needed, and the capping limiting rod 1122 can effectively limit the vibration space of the capping, resulting in high cost-effectiveness.

[0112] Furthermore, the assembly tray 244 includes a first assembly tray 2441 and a second assembly tray 2442. The first assembly tray 2441 is located above the second assembly tray 2442. The first assembly tray 2441 is provided with a second clamping member for clamping the faucet. The second assembly tray 2442 includes a rotating member for driving the second assembly tray 2442 to rotate. The second assembly tray 2442, carrying the faucet without a cap, rotates to the side of the second clamping member on the first assembly tray 2441. The second clamping member clamps the faucet without a cap. The capping robot 243 installs a cap on the faucet without a cap. After installation, the second assembly tray 2442 rotates, and the capping robot 243 installs caps on subsequent faucets without caps.

[0113] To facilitate the unloading of the installed faucets, the assembly tray 244 also includes a unloading robot 2443. The unloading robot 2443 is located above the first assembly tray 2441 and is used to grab the installed faucets and unload them. The capping robot 243 and the unloading robot 2443 are only set on one side, which makes it easier for workers to store the faucets.

[0114] Please combine Figure 21 The following is a detailed description of the flow conveyor mechanism 25 of the present invention:

[0115] Compared to traditional conveying mechanisms, the continuous conveying mechanism 25 includes a continuous conveyor belt 251 and a faucet holder 252. The faucet holder 252 is located on the continuous conveyor belt 251 and is used to fix the faucet, ensuring the stability of the faucet on the conveyor belt during each processing step. The continuous conveying mechanism 25 includes a first continuous conveying mechanism and a second continuous conveying mechanism, separated by a quality testing mechanism. The first continuous conveying mechanism is used to convey faucets with valve cores installed and faucets with handles installed. The second continuous conveying mechanism is used to convey faucets that have passed the quality testing mechanism 231 and the airtightness testing mechanism 232. Faucets that pass the quality test will be picked up from the first continuous conveying mechanism and transferred to the second continuous conveying mechanism. Faucets that fail the quality test will be picked up from the first continuous conveying mechanism and transferred to the defective product hopper 2311. Faucets that have completed the airtightness test will be conveyed to the capping processing mechanism 24 through the second continuous conveying mechanism for capping installation.

[0116] The working principle of this invention is as follows: The sealing ring, the water outlet, and the valve body are respectively placed in the sealing ring vibrating plate 111, the water outlet vibrating plate 121, and the valve body vibrating plate 131. Driven by the sealing ring vibrating plate 111, the water outlet vibrating plate 121, and the valve body vibrating plate 131, the sealing ring, the water outlet, and the valve body are brought to the first assembly mechanism 14 for assembly. After the assembly is completed, the semi-finished product is transported to the second processing unit 2 via the first assembly conveyor belt 146. In the second processing unit 2, manual operation is performed to load the valve core, handle, and cap. The valve core processing mechanism 21 installs the valve core and valve body together, and then the handle processing mechanism 22 installs the handle on the valve body. Then, the quality inspection begins in the faucet testing mechanism 23. Qualified faucets enter the airtightness test, and unqualified faucets fall into the defective product hopper 2311. Faucets that pass the airtightness test have their caps installed in the cap processing mechanism 24. Unqualified ones also enter the defective product hopper 2311. After the cap installation is completed by the cap processing mechanism 24, the assembly and testing of the entire faucet is completed.

[0117] This completes the assembly and testing process of the compact faucet assembly and testing line of this preferred embodiment.

[0118] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
