Description

TECHNICAL FIELD

[0001] The present application relates to the field of faucet assembly, in particular to a faucet assembly device. BACKGROUND

[0002] In the process of assembling the faucet valve, the sealing performance between the faucet and the valve body directly affects the working reliability and sealing life of the valve. In the prior art, the faucet is inserted into the valve body by manual or semi-automatic equipment, and the sealing effect is achieved by aligning the opening on the sealing sleeve with the valve passage. However, on the one hand, manual assembly is prone to misalignment of the sealing sleeve, resulting in inaccurate alignment of the opening with the valve passage, affecting normal use. On the other hand, the existing semi-automatic assembly equipment lacks precise positioning and automatic correction function, and it is difficult to ensure the coaxiality and sealing surface fitting quality of the faucet and the valve body during assembly.

[0003] The currently disclosed Chinese patent CN118912225B discloses a quick-mount sealing type faucet valve, which comprises a valve body and a valve plug. The valve body comprises a valve cavity for assembling the valve plug and valve pipes located at both ends of the valve cavity. The inner wall of the valve pipe extends towards the end away from the valve cavity to form an assembly ring groove for assembling a pipeline. A quick-mount sealing module is arranged in the assembly ring groove for sealing connection with the pipeline to be connected. The quick-mount sealing module comprises a self-centering guide and clamping assembly, at least three clamping blocks circumferentially distributed on the inner wall of the valve pipe, the clamping blocks having a guide slope for guiding the pipeline to enter and being elastically stretchable along the radial direction of the valve pipe, a sealing pressing assembly, a first annular air bag circumferentially arranged on the outer ring wall of the assembly inner pipe, the first annular air bag being inflatable or contractible and being capable of sealing and pressing on the inner ring wall of the pipeline after inflation, a delayed air supply retaining assembly, a plurality of gas storage components fixed circumferentially on the bottom of the assembly ring groove, a first piston rod sealingly moving in the gas storage component and extending towards the opening direction of the assembly ring groove, and a driving ring fixed with the rod body end of all first piston rods. A gas cavity is arranged in the bottom of the assembly ring groove. A first gas pipeline is connected between the gas cavity and the first annular air bag. A switching assembly is arranged between the piston bottom of the first piston rod and the bottom of the gas storage component, and is in communication or disconnected with the gas cavity. The inner wall of the valve pipe is elastically stretchable along the radial direction of the valve pipe, and the stop block is unidirectionally supplied to the driving ring.

[0004] According to the above-mentioned patent, the pipeline is inserted into the assembly ring groove, and as the pipeline is inserted to the preset depth, the sealing pressing assembly is expanded to seal and press against the inner ring wall of the pipeline, and the adsorption block of the suction assembly is extended to press against the outer ring wall of the pipeline while the outer ring wall of the pipeline is adsorbed by negative pressure. However, the lack of precise guiding or positioning structure for the alignment of the sealing sleeve and the valve body channel may cause the sealing sleeve to deviate or misalign during assembly, affecting the sealing reliability between the plug and the valve body. Therefore, there is currently a need for a plug assembly device with precise centering and positioning function of the sealing sleeve to ensure that the opening position of the sealing sleeve is accurately aligned with the valve body channel, so as to ensure that the sealing sleeve is balanced in the installation process, and to avoid deformation or misalignment caused by uneven compression.

[0016] The beneficial effects of the present application compared with the prior art are:

[0017] 1. The present application realizes accurate positioning and real-time adjustment of the opening direction of the sealing sleeve by matching the two pressure structures of the external alignment assembly with the corresponding pressure sensors. When the sealing sleeve enters the guide gap, the balls in the pressure structure move under pressure and trigger the pressure sensor, thereby judging whether the sealing sleeve is correctly aligned and dynamically correcting it through the clamp to ensure that the opening direction of the sealing sleeve always remains consistent with the valve body passage and coaxial with the valve port.

[0020] The guide column automatically slides into the opening of the sealing sleeve under the elastic action of the rubber pad, and in combination with the ball head structure, it realizes stable clamping and coaxial retention of the sealing sleeve, further improving the stability and sealing performance of the assembly process.

[0021] 3. The present application realizes stable clamping and accurate release of the sealing sleeve during assembly through the positioning structure on the clamp, and ensures accurate alignment of the valve seat and valve body connection point through the detection structure. During assembly, the positioning structure remains locked before the sealing sleeve enters the limiting gap to prevent it from shifting, and automatically unlocks after entering the limiting area to ensure the continuity and integrity of the assembly action.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means and specific purposes and functions of the application, the application will be further described in detail below in combination with the drawings and specific embodiments.

[0037] Referring to Figures 1-3 and Figures 7-12 As shown in the figure, the plug assembly device, used to assemble the plug 3 with the opening 21 sealing sleeve 2 on the valve seat 1 and the valve body 4, includes a mold 5 used to keep the passage 12 of the valve body 4 horizontal and the valve port 11 upward, a clamp 6 used to clamp and move the valve seat 1, and a tightening mechanism used to bolt 13 the valve seat 1 of the valve body 4, and further includes a guide alignment mechanism used to guide the sealing sleeve 2 into the valve body 4 and ensure that the opening 21 on the sealing sleeve 2 is aligned with the passage 12 of the valve body 4, the guide alignment mechanism includes an outer alignment assembly 7 provided on the mold 5, the outer alignment assembly 7 is located above the valve body 4, the outer alignment assembly 7 includes pressure structures 71 symmetrically arranged on both sides of the valve port 11 of the valve body 4 and pressure sensors 72 corresponding to each pressure structure 71 respectively, each pressure structure 71 can move horizontally on the mold 5, and a guide gap for the plug 3 to drive the sealing sleeve 2 to pass through can be formed between the two pressure structures 71, when the sealing sleeve 2 passes through the guide gap and the corresponding pressure structure 71 is detected by the two pressure sensors 72 to be clamped into the opening 21 of the sealing sleeve 2, the sealing sleeve 2 is in a pre-holding alignment state before entering the valve body 4, so that the sealing sleeve 2 can be accurately aligned with the passage 12 of the valve body 4 after entering the valve body 4.

[0038] The clamp 6 also has an angle adjustment function, and a driving source for driving the clamp 6 to move and adjust the angle is not shown in the figure.

[0039] The tightening mechanism is not shown in the figure.

[0040] When the assembly starts, first place the valve body 4 to be assembled on the mold 5, and ensure that the passage 12 of the valve body 4 is kept horizontal and the valve port 11 is upward through the positioning of the mold 5, to provide an accurate reference for subsequent assembly.

[0041] Subsequently, the clamp 6 is moved to the storage area of the plug 3 under the drive of the mechanical arm, and the valve seat 1 is clamped by the clamping device, the valve seat 1 has the plug 3 installed thereon and the sealing sleeve 2 pre-assembled on the plug 3 and fixed by the clamp 6. Since the clamp 6 has an angle adjustment function, the valve seat 1 can be rotated or inclined according to actual needs, so that it forms a good butt angle with the valve body 4.

[0042] With the fixture 6 slowly pushing the valve seat 1 towards the valve body 4, the sealing sleeve 2 first enters the guide gap. When the sealing sleeve 2 passes through the guide gap, the opening 21 on the sealing sleeve 2 will be in contact with the pressure structure 71, thereby triggering the corresponding pressure sensor 72. At this time, the signal feedback through the pressure sensor 72 judges whether the sealing sleeve 2 has been correctly clamped into the guide position, that is, whether the pressure structure 71 and the opening 21 on the corresponding side of the sealing sleeve 2 remain in a clamped state, thereby confirming whether the opening 21 direction of the sealing sleeve 2 is in alignment with the channel 12 of the valve body 4.

[0043] If deviation is detected, the overall valve seat 1 is rotated and corrected through the angle adjustment function of the fixture 6 until complete alignment is achieved. Once it is confirmed that the sealing sleeve 2 is in a pre-kept alignment state, at this time the two pressure structures 71 are respectively away from the valve seat 1, the fixture 6 will continue to push the valve seat 1 close to the valve body 4, so that the plug 3 gradually combines with the internal structure of the valve body 4. As the valve body 4 is about to be attached to the valve body 4, the fixture 6 releases the fixing state of the sealing sleeve 2, so that the valve seat 1 can be attached to the valve body 4.

[0044] When the valve seat 1 is completely attached to the valve body 4, the sealing sleeve 2 has completely entered the valve body 4 and is pressed on the valve body 4 by the valve seat 1, the tightening mechanism is started, and the bolt 13 for fixing is automatically sent to the specified position and is tightened in turn and symmetrically to ensure that the valve seat 1 is uniformly stressed and firmly connected. During the entire process, the guide alignment mechanism effectively solves the problem of inaccurate assembly caused by misalignment of the opening 21 of the sealing sleeve 2 and the channel 12 of the valve body 4 in the traditional assembly method, so as to facilitate the adjustment of the assembly process and improve the assembly efficiency and precision.

[0045] Referring to Figure 2 , Figure 3 and Figures 8-10 , the pressure structure 71 has a guide block 711 and a ball 712 arranged thereon to adapt to the opening 21 on the corresponding side of the sealing sleeve 2, the guide block 711 has a guide groove capable of allowing the ball 712 to move horizontally due to the downward pressure of the plug 3, the guide block 711 is provided with the pressure sensor 72 opposite the movement direction of the ball 712, and the ball 712 and the pressure sensor 72 are provided with a compression spring 721.

[0046] The mold 5 is provided with a sliding table 51 at a position corresponding to each guide block 711, and each sliding table 51 is slidingly provided with a sliding block 511 connected with the corresponding guide block 711.

[0047] The driving source for driving each sliding block 511 to move is not shown in the figure.

[0048] When the clamp 6 drives the valve seat 1 to move downward, the outer wall of the sealing sleeve 2 will contact the rolling ball 712 on the guide block 711, so that the rolling ball 712 moves horizontally along the guide groove under the downward pressure of the sealing sleeve 2. At the same time, the pressure applied by the sealing sleeve 2 can be effectively transmitted to the pressure sensor 72.

[0049] When the rolling ball 712 moves outward due to the extrusion of the sealing sleeve 2, it pushes the pressure sensor 72 through the compression spring 721, so that the sensor can detect the pressure change signal reflected by the displacement of the rolling ball 712, and judge whether the sealing sleeve 2 has correctly entered the guide position, that is, whether the rolling ball 712 is clamped into the corresponding side opening 21 of the sealing sleeve 2. In order to adjust the position of the faucet 3 together with the sealing sleeve 2 by the clamp 6, ensure that the opening 21 of the sealing sleeve 2 is adjusted in advance before entering the valve body 4, and provide reliable guarantee for the accurate assembly of the faucet 3 and the valve body 4.

[0050] Referring to Figure 2 , Figure 3 and Figures 8-10 , the guide block 711 has a guide surface that can closely fit the outer side of the sealing sleeve 2, and the guide gap is formed between the two guide surfaces. When the two guide blocks 711 are close to each other to form the guide gap, the sealing sleeve 2 is in the coaxial alignment state with the valve port 11 of the valve body 4, and when the two guide blocks 711 are away from each other, the sealing sleeve 2 can gradually move downward with the faucet 3 until the valve seat 1 contacts the valve body 4.

[0051] When the clamp 6 drives the valve seat 1 to move downward, the two guide blocks 711 are driven by the sliding block 511 to approach each other, and the guide gap suitable for the size of the sealing sleeve 2 is formed in advance. Through the position adjustment of the clamp 6, the sealing sleeve 2 can enter the guide gap, so as to ensure that the faucet 3 together with the sealing sleeve 2 is coaxial with the valve port 11 of the valve body 4.

[0052] At the same time, the rolling ball 712 triggers the pressure sensor 72 to complete the position confirmation of the opening 21 of the sealing sleeve 2. If the rolling ball 712 cannot be clamped into the corresponding side opening 21 of the sealing sleeve 2, the angle of the sealing sleeve 2 is adjusted by adjusting the angle of the valve seat 1 through the clamp 6, so that the rolling ball 712 is clamped into the corresponding side opening 21 of the sealing sleeve 2.

[0053] When the assembly enters the next stage, the two guide blocks 711 move reversely on the sliding table 51 to move away from each other, and the guide surface exits the limiting of the sealing sleeve 2, so that the sealing sleeve 2 can continue to move downward with the plug 3, smoothly pass through the valve port 11 and embed in the valve body 4, until the valve seat 1 and the valve body 4 are attached to complete the assembly action. During the whole process, the guide blocks 711 realize the efficient guiding and releasing of the sealing sleeve 2 through the precise closing and separating actions, which guarantees the continuity and accuracy of the assembly process.

[0054] Referring to Figure 2 , Figure 3 and Figures 8-10 , the upper edge of the guide surface of the guide block 711 is a chamfered edge for smoothly guiding the sealing sleeve 2 into the guide gap.

[0055] When the clamp 6 drives the valve seat 1 to move downward, so that the sealing sleeve 2 approaches the guide gap formed by the guide block 711, the chamfered edge of the upper edge of the guide surface can guide the sealing sleeve 2 during the process of entering the guide gap, so that the outer side wall of the sealing sleeve 2 can smoothly fit the guide surface and slide into the gap along the guide direction, avoiding the jamming or deviation caused by the abrupt edge.

[0056] With the sealing sleeve 2 stably entering the guide gap under the guidance of the chamfered edge, its posture is gradually corrected and accurately centered, ensuring that the subsequent ball 712 can be accurately clamped into the opening 21 of the sealing sleeve 2 and complete the orientation positioning of the opening 21 of the sealing sleeve 2.

[0057] Referring to Figure 2 , Figure 3 and Figures 8-10 , the guide alignment mechanism further includes an inner alignment assembly 8 arranged on the mold 5, the inner alignment assembly 8 is located inside the valve body 4, and the inner alignment assembly 8 includes guide structures 81 symmetrically arranged on both sides of the valve port 11 of the valve body 4. Each guide structure 81 can horizontally enter and exit the channel 12 of the valve body 4, and the two guide structures 81 can form a limiting gap for keeping the opening 21 of the sealing sleeve 2 from deviating after the sealing sleeve 2 leaves the guide gap and enters the valve body 4.

[0058] When the sealing sleeve 2 completes the preliminary alignment in the guide gap and is confirmed to be in the correct posture, the clamp 6 continues to drive the valve seat 1 to move downward, so that the sealing sleeve 2 leaves the guide gap and begins to enter the valve body 4. At this time, the inner alignment assembly 8 located inside the valve body 4 begins to play a role, and the guide structures 81 on both sides of the inner alignment assembly 8 enter the channel 12 of the valve body 4 horizontally under the drive, and form a limiting gap in the valve body 4 which is suitable for the size of the sealing sleeve 2.

[0059] When the sealing sleeve 2 passes through the valve port 11 into the limiting gap, the guide structure 81 restricts the outer side thereof, preventing the sealing sleeve 2 from being offset or rotated due to gravity or assembly force after entering the valve body 4, thereby ensuring that the opening 21 direction of the sealing sleeve 2 always remains consistent with the passage 12 of the valve body 4. As the plug 3 continues to be pressed down, the sealing sleeve 2 is stably embedded into the inside of the valve body 4 under the protection of the limiting gap, until the valve seat 1 is attached to the valve body 4 to complete the final assembly. Throughout the process, the inner alignment assembly 8 further guarantees the stability and centering accuracy of the plug 3 and the sealing sleeve 2 during the assembly process through precise limiting control.

[0060] Referring to Figure 2 , Figure 3 and Figures 8-10 , the mold 5 is provided with a sliding seat 52 connected to each guide structure 81 at a position corresponding thereto, the guide structure 81 has a guide column 811 slidingly arranged on the sliding seat 52 in the direction of the passage 12 of the valve body 4, and a rubber pad 812 connected between the guide column 811 and the sliding seat 52, when the sealing sleeve 2 enters the valve body 4, the guide column 811 is in a limiting state of being able to slide into the opening 21 on the corresponding side of the sealing sleeve 2 under the elastic action of the rubber pad 812.

[0061] The driving source for driving each of the sliding seats 52 is not shown in the figure.

[0062] When the sealing sleeve 2 enters the passage 12 of the valve body 4, the guide column 811 automatically slides into the opening 21 on the corresponding side of the sealing sleeve 2 under the elastic driving of the rubber pad 812, forming a limiting action on the sealing sleeve 2 to prevent it from being offset or rotated during subsequent assembly process. It is ensured that the opening 21 of the sealing sleeve 2 always remains aligned with the passage 12 of the valve body 4 until the valve seat 1 is completely attached and compressed against the sealing sleeve 2 to complete the final assembly. Throughout the process, the guide column 811 realizes reliable positioning and protection of the opening 21 of the sealing sleeve 2 through the elastic self-adaptive adjustment of the rubber pad 812.

[0063] Referring to Figure 2 , Figure 3 and Figures 8-10 , the two guide columns 811 each have a ball head structure 8111 at the end close to each other, which is adapted to the opening 21 on the corresponding side of the sealing sleeve 2, and the limiting gap is formed between the two ball head structures 8111.

[0064] When the sealing sleeve 2 enters the passage 12 of the valve body 4 and approaches the limiting area of the inner alignment assembly 8, the two guide columns 811 move towards the center of the valve body 4 under the elastic action of the rubber pad 812, and the end close to each other respectively contacts the edge of the opening 21 on the corresponding side of the sealing sleeve 2 with the ball head structure 8111.

[0065] Due to the shape of the ball head structure 8111 and the opening 21 of the sealing sleeve 2, the ball head structure 8111 can smoothly slide into the opening 21 during the movement of the guide column 811 and form a stable limiting gap between them. At this time, the two ball head structures 8111 work together to accurately position and clamp the opening 21 of the sealing sleeve 2 from both sides, preventing it from shifting or rotating in the valve body 4, thereby ensuring that the sealing sleeve 2 always maintains a coaxial state with the passage 12 of the valve body 4. As the assembly process continues, this limiting action continues until the valve seat 1 is fully compressed against the sealing sleeve 2, providing strong protection for the sealing performance and structural stability of the final assembly.

[0066] Referring to Figure 2 , Figures 4-6 , Figure 11 and Figure 12 , the fixture 6 is provided with a positioning structure 61 capable of fixing the sealing sleeve 2. Before the sealing sleeve 2 enters the limiting gap, the positioning structure 61 is in a locked state to keep the sealing sleeve 2 stable, and after the sealing sleeve 2 enters the limiting gap, the positioning structure 61 is in an unlocked state to keep the sealing sleeve 2 fully assembled into the valve body 4.

[0067] Before the fixture 6 moves downward with the valve seat 1 to make the sealing sleeve 2 enter the limiting gap, the positioning structure 61 on the fixture 6 is in a locked state to exert a stable clamping force on the sealing sleeve 2, ensuring that it maintains a fixed posture during the assembly process and does not shift or rotate due to external forces. At this time, the sealing sleeve 2 accurately passes through the guide gap under the cooperation of the guide positioning mechanism and gradually approaches the limiting area inside the valve body 4.

[0068] Once the sealing sleeve 2 enters the limiting gap and is stably positioned by the inner positioning assembly 8, the positioning structure 61 on the fixture 6 is immediately switched to an unlocked state, releasing the clamping constraint on the sealing sleeve 2, so that it can continue to move downward with the faucet 3 and smoothly embed into the valve body 4 until the valve seat 1 is in contact with the valve body 4. During the entire process, the positioning structure 61 effectively guarantees the stability and assembly integrity of the sealing sleeve 2 during the key assembly stage through precise locking and releasing control.

[0069] Referring to Figure 2 , Figures 4-6 , Figure 11 and Figure 12 , the positioning structure 61 has two clamping blocks 611 symmetrically arranged on both sides of the faucet 3. The clamping blocks 611 are made of rubber, and the fixture 6 is provided with a support plate 612 corresponding to each clamping block 611. Each clamping block 611 can move on the corresponding support plate 612 towards the faucet 3, and when the valve seat 1 is about to contact the valve body 4, the two clamping blocks 611 gradually move away from the valve seat 1 area.

[0070] The driving source for driving the movement of the clamping blocks 611 is not shown in the figure.

[0071] When the valve seat 1 gradually approaches the valve body 4 under the action of the clamp 6, and the sealing sleeve 2 has completed the alignment and entered the limiting gap, the two rubber clamping blocks 611 on the clamp 6 still maintain the clamping state of the sealing sleeve 2, ensuring that it is stable and does not deviate during assembly.

[0072] When the valve seat 1 continues to descend and is about to contact the valve body 4, the two clamping blocks 611 act synchronously and drive the two clamping blocks 611 to gradually move away from the faucet 3 on their corresponding support plates 612, thereby withdrawing from the valve seat 1 region. Ensure that the sealing sleeve 2 can be completely and smoothly assembled into the valve body 4, while ensuring that the fit of the valve seat 1 and the valve body 4 is not hindered.

[0073] Referring to Figure 4 and Figure 6 , the mold 5 and the support plate 612 are cooperatively provided with a detection structure capable of sensing whether the connection point between the valve seat 1 and the valve body 4 is aligned after the sealing sleeve 2 is assembled, the detection structure has a photoelectric sensor 62 provided on the mold 5 and a sensing point 621 provided on the support plate 612.

[0074] When the sealing sleeve 2 is assembled, the connection point between the valve seat 1 and the valve body 4 is aligned and confirmed by the detection structure between the mold 5 and the support plate 612 of the clamp 6 at this time. In this process, the photoelectric sensor 62 and the sensing point 621 cooperate with each other, when the support plate 612 moves to the predetermined position with the clamp 6, the sensing point 621 enters the detection area of the photoelectric sensor 62 and triggers a signal feedback.

[0075] According to the response of the photoelectric sensor 62, it is judged whether the bolt 13 hole position of the valve seat 1 and the valve body 4 is in accurate alignment state, if the signal is normal, it indicates that the alignment is accurate, and the subsequent tightening of the bolt 13 operation can continue.

[0076] If the signal is abnormal or not triggered, it means that there is deviation, the assembly process will be paused and the clamp 6 position will be adjusted to correct the angle of the valve seat 1, so as to ensure that the valve seat 1 and the valve body 4 can be connected accurately. The whole process realizes non-contact and high-precision alignment detection through photoelectric sensing method, which improves the assembly reliability and automation level.

[0077] The present application realizes real-time detection and dynamic adjustment of the opening 21 direction of the sealing sleeve 2 through the cooperation of the pressure structure 71 of the outer alignment assembly 7 and the sensor, ensuring that it is always aligned with the channel 12 of the valve body 4. At the same time, the guide gap is formed between the guide blocks 711, which ensures that the sealing sleeve 2 enters the valve body 4 smoothly.

[0078] The guide column 811 of the inner alignment assembly 8 combines the elasticity of the rubber pad 812 and the ball head structure 8111, and after the sealing sleeve 2 enters the valve body 4, the sealing sleeve 2 is secondarily limited and stably clamped to prevent deviation or rotation, and the assembly precision and sealing performance are further improved.

[0079] In the process, the positioning structure 61 on the clamp 6 reliably clamps the sealing sleeve 2 and accurately releases at the appropriate time, and the detection structure composed of the photoelectric sensor 62 and the sensing point 621 realizes high-precision identification and alignment confirmation of the connection point of the valve seat 1 and the valve body 4, effectively ensuring accurate matching of the bolt 13 hole position. Not only solves the problems of easy deviation and difficult alignment of the sealing sleeve 2 in traditional assembly, but also significantly improves the assembly efficiency, automation level and product qualification rate.

[0080] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
