[0002] During the production process of smart water meters, multiple parts inside the water meter shell need to be assembled. The assembly of smart water meters is mainly completed through assembly line operations. On the surface of a long assembly table, multiple operators assemble the parts of the smart water meter in turn.

[0003] At present, when assembling and processing the water meter shell, the existing assembly table is not convenient for adjusting the position of the smart water meter, which reduces the flexibility of the operator's work during assembly and affects the assembly efficiency. At the same time, the water meter shell in the existing assembly table is not properly corrected or missing after placement. The water meter shell is usually directly positioned and fixed on the assembly table by fasteners, which is prone to position errors of the water meter shell, affecting the smooth press-fitting of parts in the water meter shell, thereby resulting in poor press-fitting effect and efficiency.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figures 1 to 7 As shown, a production and assembly station for a smart water meter according to the present invention comprises a bracket 1, a conveyor belt 2 is installed on the bracket 1, the conveyor belt 2 is driven by a motor, a driving motor outer casing 11 is installed on the bracket 1, and the motor is located below the driving motor outer casing 11; The bracket 1 is divided into a loading area I, an assembly area II and a unloading area III from left to right. The bracket 1 is also provided with an assembly unit, which includes a press-fitting module 6 and a correction module. The correction modules are evenly arranged on the conveyor belt 2. The press-fitting module 6 presses the components into the water meter housing 5 after correction and positioning by the correction module to complete the assembly. The press-fitting module 6 is located in the assembly area II on the bracket 1; The correction module includes a card block 3, and the card block 3 includes a fixed end 31 and a free end 32. The water meter housing 5 is located in an assembly space formed by the combination of the inner side surfaces of the fixed end 31 and the free end 32. The fixed end 31 is fixedly installed on the conveyor belt 2. A mounting hole 311 is opened on the fixed end 31. A light rod 321 is slidably installed in the mounting hole 311. The other end of the light rod 321 is installed on the free end 32. A spring 312 is installed between the light rod 321 and the bottom surface of the mounting hole 311. A magnet block 4 is installed at the loading area I on the bracket 1, and a magnetic block 322 is installed on the free end 32 of the clamping block 3. The magnet block 4 and the magnetic block 322 are aligned with each other, and the magnetic attraction between the magnet block 4 and the magnetic block 322 is greater than the elastic force of the spring 312; The vertical surface and bottom surface of the inner side surface of the free end 32 are provided with buffer points, which are made of elastic material. The vertical surface of the inner side surface of the fixed end 31 is provided with positioning points, which are made of adhesive silicone. The buffer points and the fixing points are tiny raised dots. The press-fitting module 6 includes a rotating cylinder 61, which is mounted on the bracket 1, and a rotating plate 62 is mounted on the rotating cylinder 61. Both ends of the rotating plate 62 are mounted with lifting cylinders 63, and a grabbing cylinder 64 is mounted on the lifting cylinder 63. The grabbing cylinder 64 is used to grab the moving parts. When assembling the smart water meter, the water meter housing 5 is placed from the loading area I onto the correction module, and the water meter housing 5 is corrected and fixed by the correction module to ensure the accurate position of the water meter housing 5. Then, the water meter housing 5 is driven to the assembly area II by the conveyor belt 2, so that the staff can press the parts into the water meter housing 5. Then, the water meter housing 5 continues to move to the area where the press-fitting module 6 is located, and the remaining parts are press-fitted onto the water meter housing 5 by the press-fitting module 6 to complete the assembly of the smart water meter. Then, the assembled smart water meter moves to the unloading area III and leaves the assembly table from the unloading area III. At the same time, when the water meter housing 5 moves to the area where the press-fitting module 6 is located, the lifting cylinder 63 drives the grabbing cylinder 64 that has been carrying the parts to move downward, so that the parts are pressed downward onto the water meter housing 5 after the correction position, and the assembly of the smart water meter is completed. At the same time, after the press-fitting is completed, the grabbing cylinder 64 releases the grabbed parts, and then the lifting cylinder 63 is retracted upward, driving the grabbing cylinder 64 back to the original position, and the smart water meter that has been pressed and assembled continues to move toward the unloading area III along with the conveyor belt 2. At the same time, the grabbing cylinder After 64 returns to the original position, the rotating cylinder 61 is actuated to rotate the rotating plate 62, thereby causing the lifting cylinders 63 at both ends of the rotating plate 62 to exchange positions with each other, so as to move the other grabbing cylinder 64 carrying the parts to the top of the correction module. At the same time, the lifted cylinder 63 after the exchange of positions will drive the grabbing cylinder 64 that has not grabbed the parts to move downward and grab new parts. After that, the lifted cylinder 63 drives the grabbing cylinder 64 that has grabbed the parts again to return to the original position, waiting to move to the top of the correction module next time. At the same time, when the conveyor belt 2 drives the correction module to move to the loading area I, the card block 3 in the correction module will be attracted by the magnet block 4 installed on the bracket 1, so that the free end 32 and the fixed end 31 in the card block 3 are separated from each other by an end distance, so that the water meter housing 5 is placed in the assembly space on the card block 3. After that, after the correction module drives the water meter housing 5 to move to the assembly area II, the magnet block 4 on the bracket 1 is relatively staggered with the correction module, so that the magnet block 4 and the magnetic block 322 are no longer relative to each other, and the magnetic attraction disappears, thereby Under the action of the spring 312, the light rod 321 is retracted into the mounting hole 311, that is, the separated free end 32 is again fitted toward the fixed end 31, so as to adjust the position and posture of the water meter housing 5 in the assembly space, so that the water meter housing 5 and the inner wall of the assembly space are fitted with each other, thereby correcting the position of the water meter housing 5 to ensure the position accuracy of the water meter housing 5 during assembly, and avoiding the inaccurate position of the water meter housing 5 when the staff and the press-fitting module 6 press-fit the parts into the water meter housing 5, thereby affecting the press-fitting effect and efficiency; At the same time, because the free end 32 and the fixed end 31 on the card block 3 are separated from each other when the water meter housing 5 is placed, there is a relatively small gap between the assembly space on the card block 3 and the water meter housing 5, so that the loading and placement of the water meter housing 5 are convenient. At the same time, the relatively small gap between the water meter housing 5 and the assembly space can reduce the distance or angle of movement of the water meter housing 5 during position correction and fixation, so as to quickly correct the position of the water meter housing, and can also prevent the water meter housing 5 from moving too far and too fast during the correction process, resulting in bumps and scratches on the surface of the water meter housing 5. At the same time, the corrected water meter housing 5 can also avoid the situation where the press-fitting failure caused by the position error and then damage the water meter housing 5, thereby avoiding affecting the appearance quality of the smart water meter after assembly. At the same time, since a buffer point is provided on the free end 32, when placing the water meter housing 5, the water meter housing 5 is placed from a position close to the free end 32, so as to buffer the process of placing the water meter housing 5, thereby avoiding collision during the placement process and damaging the surface of the water meter housing 5. At the same time, when the free end 32 is reattached to the fixed end 31, the water meter housing 5 is slightly pushed, and the correction is completed when the water meter housing 5 contacts the inner wall of the fixed end 31. At this time, the water meter housing 5 contacts the positioning point on the inner wall of the fixed end 31, and the water meter housing 5 is fixed to the fixed end 31 by the viscosity of the positioning point itself. The shell 5 is positioned and corrected to ensure the accurate position of the water meter shell 5, to prevent the transmission belt 2 from vibrating during movement, causing the water meter shell 5 to be displaced and the correction to fail, affecting the subsequent press-fitting of parts. At the same time, due to the setting of buffer points and positioning points, the water meter shell 5 and the card block 3 are isolated to avoid excessive force on the water meter shell 5 during the subsequent press-fitting process, thereby damaging the surface paint layer of the water meter shell 5. At the same time, after the smart water meter is assembled, since the buffer points and positioning points are tiny raised dots, the process of removing the smart water meter from the correction module will not be disturbed.

[0020] As an embodiment of the present invention, the magnet block 4 is composed of a plurality of magnet blocks, and the magnetic magnitude of the magnet blocks gradually decreases along the forward direction of the conveyor belt 2; The free end 32 is composed of multiple parts, and the parts of the free end 32 slide relative to each other; After the water meter housing 5 is placed in the correction module, as the correction module gradually moves from the loading area I to the assembly area II, the various parts of the free end 32 in the correction module also pass through the area where the magnet block 4 is located in sequence. At the same time, since the magnet block 4 is also composed of multiple parts and the magnetic magnitude gradually decreases along the forward direction of the conveyor belt 2, during the movement of the free end 32, the magnetic attraction of the various parts of the free end 32 will gradually decrease, and the various parts of the free end 32 will slowly approach the fixed end 31 under the action of the corresponding spring 312, so that the card block 3 in the correction module can gradually, It closes slowly, and then relatively slowly pushes the water meter housing 5 to move in the block, completes the position correction of the water meter housing 5 in the block 3, and facilitates the smooth progress of subsequent pressing, thereby avoiding the conveyor belt 2 driving the correction module to quickly leave the loading area I, causing the free end 32 to relatively suddenly lose the attraction of the magnet block 4, causing the free end 32 to hit the water meter housing 5, and relatively quickly pushes the water meter housing 5 to move and correct, causing the position of the water meter housing 5 to shift and tilt, affecting the correction effect of the water meter housing 5, or causing the surface of the water meter housing 5 to be damaged, affecting the assembly accuracy and assembly effect of the smart water meter.

[0021] As an embodiment of the present invention, a shielding layer 41 is installed outside the magnet block 4, the opening of the shielding layer 41 is aligned with the magnetic block 322, and a blocking block 42 is movably installed on the shielding layer 41, and the blocking block 42 is located between the magnet block 4 and the magnetic block 322; By installing a shielding layer 41 on the outside of the magnet block 4, the magnetic force of the magnet block 4 when aligning with the magnetic block 322 on the free end 32 is maximized, thereby avoiding or reducing the influence of the magnet block 4 on the free end 32 after the correction module enters the assembly area II. At the same time, by installing the blocking block 42, when the magnet block 4 attracts the magnetic block 322 on the free end 32, the moving distance of the free end 32 is limited, and the free end 32 is prevented from being completely attached to the magnet block 4 and affecting the driving of the correction module by the conveyor belt 2. At the same time, by replacing different blocking blocks 42, the moving distance of the free end 32 toward the magnet block 4 is increased, and the size of the water meter housing 5 on which the correction module can be placed is increased, thereby improving the application range of the assembly table.

[0022] As an embodiment of the present invention, a placement groove 21 is provided on the conveyor belt 2, and the placement groove 21 is open toward the side of the assembler, and the card block 3 is installed in the placement groove 21, and the card block 3 and the bottom surface of the placement groove 21 are installed with magnetic strips 22 that attract each other; Since the upper surface of the bracket 1 is flush with the bottom of the placement groove 21, when the position of the smart water meter needs to be adjusted during the assembly process of the smart water meter, the assembler pushes the correction module along the opening direction of the placement groove 21, so that the correction module smoothly leaves the conveyor belt 2 and slides onto the surface of the bracket 1, so that the smart water meter can be easily assembled or the parts in the water meter housing 5 can be adjusted and replaced, and the conveyor belt 2 is prevented from continuously driving the correction module to move, which affects the assembly process of the smart water meter by the assembler. At the same time, after the adjustment is completed, the assembler pushes the correction module to slide back into the vacant placement groove 21 on the conveyor belt 2, so that the correction module re-enters the subsequent assembly work; At the same time, after the correction module returns to the placement slot 21, the card block 3 in the correction module and the magnetic strip 22 on the bottom surface of the placement slot 21 will attract each other, thereby fixing the correction module on the conveyor belt 2, avoiding shaking, displacement or even falling off of the correction module when it moves synchronously with the conveyor belt 2, and ensuring the smooth assembly of the smart water meter.

[0023] As an embodiment of the present invention, the magnetic strips 22 are distributed in multiple groups in an array, the magnetic directions of the magnetic strips 22 in the placement slots 21 are inconsistent, and the magnetic strips 22 are only located in the area where the fixed end 31 is located; The magnetic strips 22 arranged in an array and the magnetic pole directions of the magnetic strips 22 in the placement slot 21 are inconsistent, so that after the correction module enters the placement slot 21, the magnetic poles and positions between the clamping block 3 and the magnetic strips 22 in the placement slot 21 are matched with each other, so that the correction module is stably fixed in the placement slot 21, and the position accuracy and position repeatability of the correction module in the placement slot 21 are high, thereby ensuring the assembly accuracy and assembly effect; At the same time, since the magnetic strip 22 is only located in the area where the fixed end 31 is located, when the correction module is in the loading area I, the free end 32 can be easily displaced when it is affected by the magnetic attraction of the magnet block 4. After the correction module enters the assembly area II, the free end 32 can be easily re-adapted to the fixed end 31 under the action of the spring 312, thereby correcting the position of the water meter housing 5 and ensuring the smooth press-fitting of subsequent components.

[0024] As an embodiment of the present invention, a baffle 23 is installed on the bracket 1, and the baffle 23 is located below the conveyor belt 2; Since the correction module and the water meter housing 5 are relatively heavy, the baffle 23 under the conveyor belt 2 is used to support the conveyor belt 2 to ensure the stable operation of the conveyor belt 2 and prevent the conveyor belt 2 from shaking or deforming during the movement of the correction module, thereby ensuring the assembly accuracy and assembly effect of the smart water meter.

[0025] As an embodiment of the present invention, a positioning groove is provided on the baffle 23, the conveyor belt 2 is located in the positioning groove, and the width of the positioning groove is the same as the width of the conveyor belt 2; A connecting cavity 231 is provided in the baffle plate 23, and a suction hole 232 is provided on the baffle plate 23. The suction holes 232 are close to the edges of both sides of the conveyor belt 2. The suction holes 232 are connected to each other through the connecting cavity 231, and the connecting cavity 231 is connected to an external negative pressure gas source. By providing a positioning groove on the baffle 23, and the width of the positioning groove is the same as the width of the conveyor belt 2, the conveyor belt 2 is fully limited to prevent the conveyor belt 2 from being skewed or offset due to the gravity of the correction module and the water meter housing 5 during operation, thereby ensuring smooth assembly of the smart water meter. At the same time, during the operation of the conveyor belt 2, the external negative pressure air source transmits the negative pressure to the suction hole 232, so that the suction hole 232 adsorbs and fixes the conveyor belt 2 running in the positioning groove, ensuring that the conveyor belt 2 is always attached to the positioning groove, further reducing the running of the conveyor belt 2. The possibility of skewness and deviation during operation is eliminated, so that the conveyor belt 2 drives the correction module and the water meter housing 5 to move stably, which is convenient for the assembly of the smart water meter and improves the assembly effect and assembly efficiency. At the same time, the suction holes 232 are close to the edges on both sides of the conveyor belt 2 to ensure that the edges of the conveyor belt 2 will not easily jump out of the positioning groove, thereby ensuring that the position of the water meter housing 5 after correction is accurate, and there will be no deviation or skew, etc., to ensure that the subsequent assembly of the smart water meter is smooth, and to avoid too many suction holes 232, which will cause excessive adsorption force on the conveyor belt 2 and affect the normal operation of the conveyor belt 2.

[0026] As an embodiment of the present invention, a contact sheet 323 is installed at the opening of the free end 32, and the contact sheet 323 is a fluff layer; Since the water meter housing 5 will be placed in the loading area I at a position close to the free end 32, a contact piece 323 made of a fluff layer is installed at the opening of the free end 32, which further reduces the possibility of bumps and scratches on the water meter housing 5 during placement, ensuring the good appearance quality of the assembled smart water meter.

[0027] The specific workflow is as follows: When assembling the smart water meter, the water meter housing 5 is placed from the loading area I onto the correction module, and the water meter housing 5 is corrected and fixed by the correction module. Then, the water meter housing 5 is driven to the assembly area II by the conveyor belt 2, so that the staff can press the parts into the water meter housing 5. Then, the water meter housing 5 continues to move to the area where the press-fitting module 6 is located, and the remaining parts are press-fitted onto the water meter housing 5 by the press-fitting module 6, so that the assembly of the smart water meter is completed. Then, the assembled smart water meter moves to the unloading area III and leaves the assembly table from the unloading area III. At the same time, when the water meter housing 5 moves to the area where the press-fitting module 6 is located, the lifting cylinder 63 drives the grabbing cylinder 64 that has been carrying the parts to move downward, and presses the parts downward onto the water meter housing 5 after the correction position, completing the assembly of the smart water meter. At the same time, after the press-fitting is completed, the grabbing cylinder 64 releases the grabbed parts, and then the lifting cylinder 63 is retracted upward, driving the grabbing cylinder 64 back to the original position, and the smart water meter that has been press-fitted continues to move toward the unloading area III along with the conveyor belt 2. At the same time, the grabbing cylinder After 64 returns to the original position, the rotating cylinder 61 is actuated to rotate the rotating plate 62, thereby causing the lifting cylinders 63 at both ends of the rotating plate 62 to exchange positions with each other, and the other grabbing cylinder 64 carrying the parts is moved to the top of the correction module. At the same time, the lifted cylinder 63 after the exchange of positions will drive the grabbing cylinder 64 that has not grabbed the parts to move downward and grab new parts. After that, the lifted cylinder 63 drives the grabbing cylinder 64 that has grabbed the parts again to return to the original position, waiting to move to the top of the correction module next time; At the same time, when the conveyor belt 2 drives the correction module to move to the loading area I, the card block 3 in the correction module will be attracted by the magnet block 4 installed on the bracket 1, so that the free end 32 and the fixed end 31 in the card block 3 are separated from each other by an end distance, and the water meter housing 5 is placed in the assembly space on the card block 3. After that, after the correction module drives the water meter housing 5 to move to the assembly area II, the magnet block 4 on the bracket 1 and the correction module are relatively staggered, so that the magnet block 4 and the magnetic block 322 are no longer relative to each other, and the magnetic attraction disappears, so that under the action of the spring 312, the light rod 321 is retracted into the installation hole 311, that is, the separated free end 32 is re-fitted toward the fixed end 31, and the position and posture of the water meter housing 5 in the assembly space are adjusted, so that the water meter housing 5 and the inner wall of the assembly space are fit to each other, and the position of the water meter housing 5 is corrected; At the same time, because the free end 32 and the fixed end 31 on the clamp 3 are separated from each other when the water meter housing 5 is placed, there is a relatively small gap between the assembly space on the clamp 3 and the water meter housing 5, which is convenient for loading and placing the water meter housing 5. At the same time, the relatively small gap between the water meter housing 5 and the assembly space reduces the moving distance or angle of the water meter housing 5 during position correction and fixation, and the position of the water meter housing is quickly corrected. It can also prevent the water meter housing 5 from moving too far and too fast during the correction process, resulting in bumps and scratches on the surface of the water meter housing 5. At the same time, since the buffer point is provided on the free end 32, when the water meter housing 5 is placed, the water meter housing 5 is placed from a position close to the free end 32, so that the process of placing the water meter housing 5 is buffered. At the same time, when the free end 32 is re-attached to the fixed end 31, the water meter housing 5 is slightly pushed, and the correction is completed when the water meter housing 5 contacts the inner wall of the fixed end 31. At this time, the water meter housing 5 will contact the positioning point on the inner wall of the fixed end 31, and the water meter housing 5 is positioned and corrected by the viscosity of the positioning point itself. At the same time, since the buffer point and the positioning point are provided, the water meter housing 5 is isolated from the card block 3, so as to avoid excessive force on the water meter housing 5 during the subsequent press-fitting process, thereby damaging the surface paint layer of the water meter housing 5; Since the magnet block 4 is also composed of multiple parts and the magnetic magnitude gradually decreases along the forward direction of the conveyor belt 2, during the movement of the free end 32, the magnetic attraction of each part of the free end 32 will gradually decrease, and each part of the free end 32 will slowly approach the fixed end 31 under the action of the corresponding spring 312, so that the block 3 in the correction module can be gradually and slowly closed, and then the water meter housing 5 is relatively slowly pushed to move in the block, and the position correction of the water meter housing 5 in the block 3 is completed, so as to avoid the conveyor belt 2 driving the correction module to quickly leave the feeding area I, resulting in the free end 32 relatively suddenly losing the attraction of the magnet block 4, causing the free end 32 to hit the water meter housing 5, and relatively quickly pushing the water meter housing 5 to move and correct, so that the position of the water meter housing 5 is offset, skewed, or the surface of the water meter housing 5 is damaged; By installing a shielding layer 41 on the outside of the magnet block 4, the magnetic force of the magnet block 4 when aligning with the magnetic block 322 on the free end 32 is maximized, thereby avoiding or reducing the influence of the magnet block 4 on the free end 32 after the correction module enters the assembly area II. At the same time, the installed blocking block 42 limits the moving distance of the free end 32 and prevents the free end 32 from being completely attached to the magnet block 4. During the assembly process of the smart water meter, when the position of the smart water meter needs to be adjusted, the assembler pushes the correction module along the opening direction of the placement slot 21, so that the correction module smoothly leaves the conveyor belt 2 and slides onto the surface of the bracket 1, which is convenient for assembling the smart water meter or adjusting and replacing the parts in the water meter housing 5. At the same time, after the adjustment is completed, the assembler pushes the correction module to slide back into the vacant placement slot 21 on the conveyor belt 2, so that the correction module re-enters the subsequent assembly work; At the same time, after the correction module returns to the placement slot 21, the block 3 in the correction module and the magnetic strip 22 on the bottom surface of the placement slot 21 will attract each other, fixing the correction module on the conveyor belt 2; The magnetic strips 22 arranged in an array and the magnetic pole directions of the magnetic strips 22 in the placement slot 21 are inconsistent, so that after the correction module enters the placement slot 21, the magnetic poles and positions between the clamping block 3 and the magnetic strips 22 in the placement slot 21 are matched with each other, so that the correction module is stably fixed in the placement slot 21, and the position accuracy and position repeatability of the correction module in the placement slot 21 are high; At the same time, since the magnetic strip 22 is only located in the area where the fixed end 31 is located, when the correction module is in the loading area I, the free end 32 is affected by the magnetic attraction of the magnet block 4, and the free end 32 can be easily displaced. After the correction module enters the assembly area II, the free end 32 can be easily re-attached to the fixed end 31 under the action of the spring 312, so as to correct the position of the water meter housing 5. Since the weight of the calibration module and the water meter housing 5 is relatively large, the baffle 23 under the conveyor belt 2 is used to support the conveyor belt 2 to ensure the stable operation of the conveyor belt 2; By opening a positioning groove on the baffle 23, and the width of the positioning groove is the same as the width of the conveyor belt 2, the conveyor belt 2 is fully limited. At the same time, during the operation of the conveyor belt 2, the external negative pressure gas source transmits the negative pressure to the suction hole 232, so that the suction hole 232 adsorbs and fixes the conveyor belt 2 running in the positioning groove, ensuring that the conveyor belt 2 is always attached to the positioning groove. At the same time, the suction holes 232 are close to the edges of both sides of the conveyor belt 2, ensuring that the edges of the conveyor belt 2 will not easily jump out of the positioning groove, and avoiding too many suction holes 232, which will cause excessive adsorption force on the conveyor belt 2. Since the water meter housing 5 will be placed in the loading area I at a position close to the free end 32, a contact piece 323 made of a fluff layer is installed at the opening of the free end 32, which further reduces the possibility of bumps and scratches on the water meter housing 5 during placement, ensuring the good appearance quality of the assembled smart water meter.
