Description

Technical Field

[0001] This invention relates to water meter digit assembly technology, and more particularly to an automated assembly device for arranging water meter digits in combination. Background Technology

[0002] The meter display on the water meter head is the component used to display the amount of water used. It includes a digit wheel chamber formed by a housing and a cover. Inside the digit wheel chamber are axles and toothed shafts. Multiple digit wheels are strung together in parallel on the axles. The cooperation of multiple digit wheels forms multiple levels of digit wheels with different bases such as ones, tens, hundreds, thousands, etc., thereby realizing the function of displaying the water usage scale on the meter head.

[0003] Currently, the assembly process of the aforementioned metering displays is still done manually, which is slow and inefficient. The industry naturally hopes to automate the assembly of the metering displays on water meter heads. When assembling the multiple digits into the water meter, a rotating shaft is needed to connect them in series, facilitating assembly between the digits and the digit housing. However, existing technology lacks an automated device for assembling multiple digits with the rotating shaft, requiring manual operation, which is inefficient. When the digits are connected in series with the rotating shaft, a retaining structure is needed to limit their position. Therefore, this application provides a structure that can limit the position of multiple digits to facilitate the insertion of the rotating shaft and achieve the series connection of multiple digits. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes an automated assembly device for arranging water meter dials.

[0005] An automated assembly device for arranging water meter dials, comprising: The workbench is surrounded by a type wheel feeding mechanism and a rotating shaft feeding mechanism. The type wheel feeding mechanism is provided in multiple locations. The workbench is equipped with a rotating disk and a conveying mechanism. Multiple assembly mechanisms are set on the rotating disk. The assembly mechanisms are used to position multiple character wheels so that they are evenly arranged. At the same time, they cooperate with the rotating shaft feeding mechanism to insert into the rotating shaft and connect them in series by inserting the rotating shaft into the middle of the character wheels. The assembly mechanism includes: An assembly base is provided with a accommodating area in the middle of which the character wheels are evenly arranged. The accommodating area is open at one end and has multiple sliding holes around it. The sliding holes are connected to the accommodating area through a connecting port. A spring, a slider, and a plug are provided in the sliding holes. The slider extends into the accommodating area through the connecting port. A mounting base is provided at one end of the assembly base. The mounting base is located at the end away from the opening of the receiving area. The end of the mounting base facing the assembly base forms a mounting area. The mounting area is provided with a rotating rod, symmetrically arranged guide rods, and multiple hinge shafts. A belt is sleeved on the rotating rod, guide rods, and hinge shafts. A motor mounted on a mounting base, the motor having a first gear and the rotating rod having a second gear, the first gear and the second gear being meshed together; A movable component is mounted on the hinge shaft, and the movable components together form a circular area. The rotating shaft passes through the circular area and wipes the surface of the rotating shaft.

[0006] In this invention, the assembly base is provided with a through groove, which is located at the upper end of the receiving area.

[0007] In this invention, the assembly base is provided with a first through hole, and the mounting base is provided with a second through hole in the middle. The inner diameters of the first through hole and the second through hole are equal. The first through hole communicates with the receiving area, and the second through hole communicates with the mounting area.

[0008] In this invention, the movable part consists of a hinge end and a movable end. The hinge end has a hinge hole in the middle that mates with the hinge shaft, and the movable end has a contact arc surface formed on its inner wall.

[0009] In this invention, the inner wall of the belt is provided with a plurality of first teeth, and the outer wall of the hinge end is provided with a plurality of second teeth that cooperate with the first teeth.

[0010] In this invention, the sliding member is composed of a sliding part, a connecting part, and a blocking part. The sliding part is disposed in the sliding hole, the connecting part is disposed in the communication port, and the blocking part is disposed in the receiving area.

[0011] In this invention, the assembly base is provided with symmetrically arranged arc-shaped grooves, and a deformation member is provided in the arc-shaped groove. One end of the deformation member is fixed in the arc-shaped groove by bolts, and the other end extends into the receiving area.

[0012] In this invention, the cross-section of the deformable component is arc-shaped, with an arc-shaped region in the middle.

[0013] In this invention, the outer wall of the deformable member is provided with a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is in contact with the inner wall of the receiving area, and an movable gap is formed between the second reinforcing rib and the first reinforcing rib. The second reinforcing rib is provided with a guide slope.

[0014] In this invention, the inner wall of the receiving area is provided with symmetrically arranged receiving grooves. When the deformable part is pushed by the character wheel, the deformable part is kept under force and deformed, and bent into the receiving groove to avoid the character wheel.

[0015] The automated assembly device for arranging water meter digits according to this invention has the following advantages: This automated assembly device automates the arrangement and assembly of the digits, achieving not only precise arrangement of multiple digits but also surface cleaning of the shaft inserted between the digits, facilitating assembly. Simultaneously, the assembly base and the limiting mechanism of the deformable components ensure that multiple digits are accurately and stably positioned within the receiving area. This keeps the digits in the same area, allowing the shaft to be directly inserted into the center of the digits, achieving a series connection of multiple digits. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 13 As shown, the automated assembly device for arranging water meter digits according to the present invention includes a workbench 1 and an assembly mechanism 2. A digit feeding mechanism 3 and a rotating shaft feeding mechanism 4 are arranged around the workbench 1. Multiple digit feeding mechanisms 3 are provided. A rotating disk 5 and a conveying mechanism 6 are provided on the workbench 1. The digit feeding mechanism 3 is used to move the water meter digits to be assembled evenly in one direction, ensuring that all digits are positioned in the same location, facilitating consistent assembly of all digits. The rotating shaft feeding mechanism 4 is used for the uniform movement of the rotating shaft. One end of the rotating shaft has a stamped protrusion (not shown in the figure), so that one end of the rotating shaft is no longer circular in cross-section, facilitating the feeding of the rotating shaft and subsequent assembly with the digits.

[0020] One end of the conveying mechanism 6 is provided with a clamping mechanism 7, which is used to clamp the assembled character wheel and shaft.

[0021] The surface of the processed shaft has dust or dust attracted by static electricity. Before assembling it with the type wheels, the surface needs to be wiped off so that the dust on the surface of the shaft can fall off, and then multiple type wheels can be connected in series.

[0022] Assembly mechanism 2 is set on rotating disk 5 and has multiple locations. Assembly mechanism 2 is used to position multiple character wheels so that they are evenly arranged. At the same time, it cooperates with rotating shaft feeding mechanism 4 to insert rotating shaft and connect the character wheels in series by inserting the rotating shaft into the middle of the character wheels.

[0023] The rotation of the rotating disk 5 drives the assembly mechanism 2 on the rotating disk 5 to rotate, causing the assembly mechanism 2 to rotate to different positions. When the character wheel feeding mechanism 3 rotates, the character wheel feeding mechanism 3 pushes the arranged character wheels into the receiving area 8 of the assembly mechanism 2. When the character wheel enters the receiving area 8, the deformable part 9 is pushed by the character wheel, causing the deformable part 9 to deform under force and bend towards the receiving groove 10, so that the deformable part 9 enters the receiving groove 10. Then, the character wheel is kept past the deformable part 9 and pushes the sliding part 11. The sliding part 11 compresses the spring 12. After the character wheel passes the deformable part 9, the deformable part 9 returns to its original position under its own elastic force. After the character wheel enters the receiving area 8, the spring 12 can maintain elastic potential energy and then push the character wheel closer to the deformable part 9, through which the deformable part 9 blocks the elastic force from the spring 12.

[0024] The elastic force of spring 12 is N1, while the external force when the deformable part 9 is pushed and bent by the character wheel is N2. N1 > N2. When spring 12 pushes the character wheel against the deformable part 9, since the outer wall of the deformable part 9 is provided with the first reinforcing rib 13 and the second reinforcing rib 14, the deformation of the deformable part 9 under force can be blocked by the cooperation of the first reinforcing rib 13 and the second reinforcing rib 14, so that the deformable part 9 cannot bend in the opposite direction, thus making the deformable part 9 only bend under force in one direction, preventing the character wheel from being pushed out of the receiving area 8 by spring 12.

[0025] Assembly mechanism 2 includes an assembly base 15, a mounting base 16, a motor 17, and a movable component 18. The assembly base 15 is mounted on the rotating disk 5 and rotates together with the rotating disk 5. Multiple driving components are located at the lower end of the rotating disk 5, and these driving components, such as the motor 17, are connected to the assembly base 15 on the rotating disk 5. When assembly mechanism 2 is driven by the rotating disk 5 to the position of the rotating shaft feeding mechanism 4, the driving component (not shown in the figure) can be activated, causing the assembly base 15 to rotate 180°. This causes the mounting base 16, which was originally facing the center of the rotating disk 5, to rotate to face the edge of the rotating disk 5, facilitating the insertion of the rotating shaft, which can then pass through the center of the character wheel. When assembly mechanism 2 rotates from the rotating shaft feeding mechanism 4 to the clamping mechanism 7, the rotating disk 5, while driving assembly mechanism 2 to rotate, causes assembly mechanism 2 to reset, rotating it another 180° to maintain the opening end of the receiving area 8 facing the edge of the rotating disk 5.

[0026] The mounting base 16 is located at one end of the assembly base 15. When the mounting base 16 faces the center of the rotating disk 5, it is convenient for the character wheel to be pushed into the receiving area 8. When the mounting base 16 faces the edge of the rotating disk 5, it is convenient for the shaft to be wiped and inserted.

[0027] The middle of the assembly base 15 forms a receiving area 8 with evenly arranged character wheels. The receiving area 8 is open at one end. Multiple sliding holes 20 are provided around the receiving area 8. The sliding holes 20 are connected to the receiving area 8 through the connecting port 21. A spring 12, a slider 11 and a plug 52 are provided in the sliding hole 20. The slider 11 extends into the receiving area 8 through the connecting port 21.

[0028] The assembly base 15 is provided with a through groove 22, which is located at the upper end of the receiving area 8. The through groove 22 is used for the insertion of the gripper 23 in the clamping mechanism 7 and the removal of the character wheel. Figure 12 and 13 As shown, the grippers 23 are inserted at both ends of the through groove 22, and the width of the grippers 23 is smaller than the width of the through groove 22. At the same time, a clearance area 24 is formed in the middle of the grippers 23, which is used to avoid the rotating shaft. The through groove 22 is open at the upper end of the receiving area 8, and the bottom surface of the receiving area 8 is arc-shaped to facilitate the cooperation with the circular character wheel.

[0029] During clamping, the two grippers 23 move closer to the center, thereby clamping the multiple character wheels in the center and removing them from the receiving area 8.

[0030] Mounting base 16 is located at one end of assembly base 15. Mounting base 16 is located at the end away from the opening of receiving area 8. The end of mounting base 16 facing assembly base 15 forms mounting area 25. Mounting area 25 is provided with rotating rod 26, symmetrically arranged guide rods 27 and multiple hinge shafts 28. A belt 29 is sleeved on rotating rod 26, guide rods 27 and hinge shafts 28.

[0031] like Figure 6 As shown, the belt 29 is guided by the rotating rod 26 and the guide rod 27, so that the belt 29 forms a rotating section 30 and a guide section 31. The rotating rod 26 is located in the middle of the rotating section 30, while the hinge shaft 28 is located in the middle of the guide section 31. The hinge shaft 28 makes the belt 29 fit more tightly against the moving part 18, so that when the belt 29 rotates, it can drive the moving part 18 to rotate, change the size of the circular area 32, and adapt to different positions of the rotating shaft.

[0032] The motor 17 is mounted on the mounting base 16. The motor 17 is equipped with a first gear 33, and the rotating rod 26 is equipped with a second gear 34. The first gear 33 and the second gear 34 are meshed together. The motor 17 drives the first gear 33 to rotate, and then the first gear 33 drives the second gear 34 to rotate. The second gear 34 drives the belt 29 to rotate through the rotating rod 26.

[0033] Movable component 18 is mounted on hinge shaft 28, and the movable components 18 together form a circular area 32. The rotating shaft passes through the circular area 32, wiping the surface of the rotating shaft. Belt 29 drives the movable component 18 to rotate, so that the movable component 18 can only rotate within a certain angle range. This causes the contact arc surface 35 on the movable component 18 to open and close, thereby changing the inner diameter of the circular area 32. This ensures that the inner diameter of the circular area 32 is adjustable to fit the diameter of the rotating shaft and the stamped part after stamping. The rotating shaft and the stamped part on the rotating shaft can pass through the circular area 32.

[0034] The movable part 18 consists of a hinge end 55 and a movable end 19. The hinge end 55 has a hinge hole 54 in the middle that mates with the hinge shaft 28. The inner wall of the movable end 19 forms a contact arc surface 35, which can fit against the surface of the rotating shaft to remove dust adhering to the surface of the rotating shaft.

[0035] By rotating the motor 17 in both directions, the belt 29 can rotate in both directions, thereby driving the moving part 18 to rotate in both directions, keeping the contact arc surface 35 on the moving part 18 open or close.

[0036] The assembly base 15 is provided with a first through hole 36, and the mounting base 16 is provided with a second through hole 37 in the middle. The inner diameters of the first through hole 36 and the second through hole 37 are equal. The first through hole 36 is connected to the receiving area 8, and the second through hole 37 is connected to the mounting area 25.

[0037] The inner wall of the belt 29 is provided with multiple first teeth (not shown in the figure), the outer wall of the hinge end 55 is provided with multiple second teeth (not shown in the figure) that cooperate with the first teeth, and the rotating rod 26 is provided with third teeth (not shown in the figure) that cooperate with the belt.

[0038] The slider 11 consists of a sliding part 38, a connecting part 39, and a blocking part 40. The sliding part 38 is disposed in the sliding hole 20, the connecting part 39 is disposed in the connecting opening 21, and the blocking part 40 is disposed in the receiving area 8. The thickness of the slider 11 is greater than the thickness of the gripper 23, so that the gripper 23 can be inserted between the symmetrically arranged sliders 11.

[0039] The assembly base 15 has symmetrically arranged arc-shaped grooves 41, and a deformable element 9 is placed in the arc-shaped groove 41. One end of the deformable element 9 is fixed in the arc-shaped groove 41 by a bolt 42, and the other end extends into the receiving area 8. The deformable element 9 has a positioning hole 46. The bolt 42 is composed of a hexagonal part 43, a threaded part 44, and a positioning pin 45, which is inserted into the positioning hole 46. The assembly base 15 has a threaded hole 47 that mates with the threaded part 44. Mounting plates 48 are provided on both sides of the assembly base 15, and the drive component is connected through the mounting plates 48.

[0040] The deformable component 9 has an arc-shaped cross-section, forming an arc-shaped region 49 in the middle. When subjected to force, the deformable component 9 bends towards the arc-shaped region 49. The outer wall of the deformable component 9 is provided with a first reinforcing rib 13 and a second reinforcing rib 14. The blocking surface 53 on the first reinforcing rib 13 contacts the inner wall of the receiving area 8. A movable gap 50 is formed between the second reinforcing rib 14 and the first reinforcing rib 13. The second reinforcing rib 14 is provided with a guiding inclined surface 51. Because the first reinforcing rib 13 and the second reinforcing rib 14 are located on the outer wall of the deformable component 9, deformation of the deformable component 9 can be avoided when it is pushed by force in the direction of the arc-shaped region 49.

[0041] like Figure 10 As shown, when the deformable part 9 is subjected to an external force in the direction of F1, the deformable part 9 deforms and rotates in the direction of F2.

[0042] A symmetrically arranged receiving groove 10 is provided on the inner wall of the receiving area 8. When the deformable part 9 is pushed by the character wheel, the deformable part 9 is kept deformed by force and bent into the receiving groove 10 to avoid the character wheel.

[0043] During operation, the character wheel feeding mechanism 3 first pushes the character wheels one by one into the receiving area 8. Then, as the rotating disk 5 rotates, when they reach the designated position, the driving component drives the assembly mechanism 2 to rotate 180°. The rotating shaft feeding mechanism 4 pushes in the rotating shaft, allowing it to reach the second through hole 37, then into the circular area 32, and finally into the first through hole 36. This allows the motor 17 to drive the movable part 18 to adjust the inner diameter of the circular area 32 to fit the rotating shaft. After the rotating shaft is pushed to the middle of the character wheel by the cylinder, it is positioned in the center of the character wheel. When the rotating shaft is inserted into the middle of the character wheel, the deformable part 9 will not deform under the action of the first reinforcing rib 13 and the second reinforcing rib 14. Finally, the rotating disk 5 drives the assembly mechanism 2 to rotate to the clamping mechanism 7. During the rotation, the driving component drives the assembly mechanism 2 to reset. When it reaches the lower end of the clamping mechanism 7, the clamping mechanism 7 can clamp the assembled character wheel and rotating shaft and transfer them to the conveying mechanism 6.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
