Description

Technical Field

[0001] This invention relates to a water meter cover assembly device, and more specifically, to an automated meter cover assembly device. Background Technology

[0002] The existing water meter cover assembly process requires assembling the cover with a cover clip and then installing the assembled cover onto the meter. This crucial step often requires manual operation. With a large production volume of meters, manual assembly not only wastes a lot of manpower and financial resources, but also results in inconsistent assembly quality of the meter cover, which cannot guarantee the normal use quality and lifespan of the meter.

[0003] For example, Chinese Patent Publication No. CN 115609264 A, published on October 28, 2022, entitled "Universal Smart Water Meter Cover Rotary Buckle Installation Device and Installation Method Thereof" discloses a water meter cover rotary buckle installation device, including a base and a water meter cover fixing seat. The rear end of the water meter cover fixing seat is provided with a column that is bolted and fixed perpendicularly to the base. This solution has good operational stability and high efficiency. However, it requires manual positioning of the cover before rotating the buckle for installation. The manual positioning of the cover greatly reduces the assembly accuracy of different covers and wastes manpower, making it unsuitable for mass production of cover assembly. Summary of the Invention

[0004] This invention overcomes the problem that meter covers cannot be automatically assembled onto instruments such as water meters, and provides an automated meter cover assembly device. This solution can automatically and accurately install meter covers onto instruments such as water meters, improving the work efficiency and assembly accuracy of the meter cover assembly line.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution: an automated watch cover assembly device, including a watch cover mounting jaw and a watch cover snap-fit ​​mounting mechanism. The watch cover mounting jaw includes two flat jaws for gripping the watch cover and a vertical jaw for engaging the watch cover snap-fit. The vertical jaw is slidably connected to the flat jaws perpendicular to their direction of movement, and the engaging end of the vertical jaw is a U-shaped groove. The two flat jaws of the watch cover mounting jaw can grip the watch cover radially, and the two flat jaws have a certain width of groove to ensure that the watch cover remains horizontal when gripped. The vertical jaw is slidably connected to the connecting arms of the two flat jaws. When the watch cover mounting jaw places the watch cover on the instrument, the two flat jaws remain stationary, and the vertical jaw begins to move toward the watch cover. Then, the U-shaped groove of the vertical jaw engages the watch cover snap-fit, pressing the connector of the watch cover snap-fit ​​into the instrument, thereby completing the installation of the watch cover. The U-shaped groove also has a limiting function for the watch cover snap-fit, preventing the watch cover snap-fit ​​from tilting or falling off during pressing. The flat jaws and the vertical jaw can be driven by a driving device such as a cylinder.

[0006] Preferably, the watch cover latching mechanism includes a first clamping block for clamping the watch cover, a second clamping block for clamping the watch cover latch, and a push rod for rotating the watch cover latch. The pushing end of the push rod is a wedge-shaped block. When the watch cover and watch cover latch are delivered to the position, the first clamping block moves downward first, pressing down on the watch cover to prevent the watch cover from changing position. Then, the second clamping block moves upward, pressing the watch cover latch into the mounting groove of the watch cover. Then, the second clamping block resets, at which point the connector of the watch cover latch is arranged radially along the watch cover. Finally, the push rod begins to move downward, pushing the connector of the watch cover latch to rotate, so that the connector is perpendicular to the watch cover and located at the bottom, preparing for the subsequent installation of the watch cover on the instrument; improving the installation efficiency and assembly accuracy of the watch cover; the wedge-shaped block on the push rod can easily hold the connector of the watch cover latch. The first clamping block, the second clamping block, and the push rod can be driven by a cylinder or other driving device. The position where the watch cover is installed has a connecting rod. The watch cover buckle includes a connector and a snap-fit ​​groove that can engage with the connecting rod.

[0007] Preferably, the present invention further includes a first rotating disk and a second rotating disk. The first rotating disk has four cover platforms evenly distributed for holding the cover; the second rotating disk has four instrument platforms evenly distributed for holding instruments. Each cover platform has a through hole near the cover latch position and corresponding to the first rotating disk. The cover platforms and instrument platforms are used to hold the cover and the instrument, respectively. The four cover platforms are used to simultaneously complete four processes when the first rotating disk rotates: cover input, cover latch assembly, cover labeling, and cover output to the second rotating disk. This greatly improves the efficiency of cover assembly and makes the structure between each workstation compact and space-saving. Similarly, the four instrument platforms are used to simultaneously complete four processes: instrument input, instrument positioning, instrument latch assembly, and output of the assembled instrument. This improves the efficiency of instrument and cover assembly, makes the structure between each workstation compact, and saves production space. The cover platforms have through holes, and corresponding through holes are also provided on the first rotating disk, facilitating the smooth engagement of the cover latch with the cover's connecting rod.

[0008] Preferably, a watch cover feeding device, a watch cover clip feeding device, a labeling device, and a watch cover mounting gripper are sequentially arranged along the rotation direction of the first rotating disk and corresponding to the four watch cover platforms. The watch cover feeding device includes a watch cover gripper for transporting the watch cover to the watch cover platform. The watch cover feeding device transports the watch cover to its output end via a vibrating plate and conveyor belt. Then, the watch cover gripper can grab the watch cover onto the watch cover platform of the first rotating disk. Similarly, the watch cover clip feeding device transports the watch cover clips into the workstation of the first rotating disk. The labeling device can perform the labeling process on the watch cover. The watch cover mounting gripper completes the grabbing and installation of the watch cover. Arranging these four workstations along the rotation direction of the first rotating disk and corresponding to the four watch cover platforms allows for a compact structure at each workstation, enabling four processes to be performed simultaneously, improving the working efficiency of the equipment, making the equipment more compact, and saving space.

[0009] Preferably, the watch cover buckle feeding device includes a conveying trough for conveying watch cover buckles. The output end of the conveying trough is provided with a first clamping block and a push rod, a first rotating disk, and a second clamping block, arranged sequentially from top to bottom. The watch cover buckle feeding device transports the watch cover buckles to its output end via a vibrating plate and the conveying trough, which can hold watch cover buckles with their snap-fit ​​grooves facing upwards. The output end of the watch cover buckle feeding device is located below the first rotating disk where the watch cover platform is located, and the through holes on the watch cover platform and the first rotating disk are directly opposite the output end of the conveying trough. The snap-fit ​​grooves of the watch cover buckles correspond to the connecting rod positions of the watch cover. After the watch cover buckles and the watch cover are transported to their positions, the structure at this location, from top to bottom, is: first clamping block and push rod, watch cover, watch cover platform through hole, first rotating disk through hole, watch cover buckle, and second clamping block. When the watch cover and cover clips are delivered to their positions, the first clamping block moves downwards first, pressing down on the watch cover to prevent its position from changing. Then, the second clamping block moves upwards, pressing the cover clips through the through holes on the first rotating disk and the watch cover platform into the mounting groove of the watch cover. Then, the second clamping block resets, at which point the connector of the cover clips is arranged radially along the watch cover. Then, the push rod begins to move downwards, pushing the connector of the cover clips to rotate, so that the connector is perpendicular to the watch cover and located at the bottom. Finally, the first clamping block resets, and the first rotating disk rotates to proceed to the next process, thus ensuring the smooth installation of the watch cover clips.

[0010] Preferably, the watch cover mounting jaws are vertically slidably connected to a slider seat that can move from the first rotating disc watch cover platform to the second rotating disc instrument platform, and the slider seat is horizontally slidably connected to a support frame. The vertical slidable connection between the watch cover mounting jaws and a slider seat allows the jaws to grip the watch cover and move it vertically. The slider seat is slidably connected to a horizontal guide rail, which is fixed to the support frame, allowing the watch cover to be horizontally transported from the first rotating disc to the instrument platform of the second rotating disc.

[0011] Preferably, the second rotating disk also includes an instrument loading mechanism and an instrument unloading mechanism. The instrument loading mechanism is equipped with instrument grippers that transport the instruments to the instrument table on the second rotating disk, and the instrument unloading mechanism is equipped with instrument rotating grippers that output the instruments from the second rotating disk. The instrument grippers can pick up the instruments and place them on the instrument table of the second rotating disk. Since the instruments are arranged neatly and orderly, their placement position changes at a certain angle after moving from the second rotating disk to the instrument unloading mechanism. Therefore, the grippers on the instrument unloading mechanism are rotatable to recalibrate the angle of the instruments. Both the instrument grippers and the instrument rotating grippers are driven by mechanisms such as cylinders, and both use a slider-rail structure to complete the input and output of the instruments.

[0012] Preferably, the first rotating disk further includes a first adjustment mechanism. This mechanism includes a retractable calibration rod that can engage with the bottom of the first rotating disk. The calibration rod has a buffer block along its vertical direction and is slidably connected to the adjustment seat of the first adjustment mechanism via a slider. The calibration rod engages with the bottom of the first rotating disk. After the first rotating disk stops rotating once, to prevent incomplete rotation and slight errors, the calibration rod on the adjustment mechanism calibrates the position of the first rotating disk, ensuring accurate positioning at all workstations. The calibration rod can be slidably connected to a guide rail for telescopic movement, or it can be installed in a hole and driven by a cylinder for telescopic movement. The guide rail or base on which the calibration rod is mounted slides along the direction perpendicular to the telescopic movement of the calibration rod via a slider, which is mounted on the adjustment seat. A buffer block is also provided in the direction of slider movement to limit and buffer the calibration rod.

[0013] Preferably, a second adjustment mechanism is provided between the instrument loading mechanism and the instrument cover mounting gripper. This second adjustment mechanism includes an adjustment gripper that is radially slidably connected to the adjustment frame of the second adjustment mechanism along the second rotating disk. The adjustment gripper is used to calibrate the position of the instrument, preventing changes in its position due to inertia when the second rotating disk rotates. When the instrument is delivered to its position, the adjustment gripper slides radially along the second rotating disk to the instrument's position, then gently clamps the instrument to calibrate its position. Afterward, the adjustment gripper resets, and the instrument, under the action of the second rotating disk, enters the next workstation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) It can automatically complete the installation of the meter cover on water meters and other instruments; (2) It can automatically complete the assembly process of the meter cover of water meters; greatly improving the assembly efficiency of the meter cover; (3) The assembly precision of the meter cover is high and the overall assembly quality is consistent; (4) The structure between each process is compact, saving space; (5) It saves manpower and material resources and facilitates enterprise production management.

[0025] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] Example: Figures 1 to 9The illustrated automated watch cover assembly equipment includes a watch cover mounting jaw 1, which is vertically slidably connected to a slider seat 20, and the slider seat 20 is horizontally connected to a support frame 21. Under the action of the slider seat 20, the watch cover mounting jaw 1 can move from above the watch cover platform 12 of the first rotating disk 10 to above the instrument panel 13 of the second rotating disk 11. The watch cover mounting jaw 1 includes two flat jaws 2 and one longitudinal jaw 3. The longitudinal jaw 3 has a U-shaped groove 4 at its engagement end and can slide vertically relative to the direction of movement of the flat jaws 2. The two flat jaws 2 of the watch cover mounting jaw 1 can radially grip the watch cover 35, and the two flat jaws 2 have grooves 34 of a certain width to ensure that the watch cover 35... 5. When being gripped, the cover 35 remains horizontal. The longitudinal claw 3 is slidably connected to the connecting arms of the two flat claws 2. When the cover mounting claw 1 places the cover 35 from the first rotating disk 10 onto the instrument on the second rotating disk 11, the two flat claws 2 remain stationary, and the longitudinal claw 3 begins to move downward toward the cover 35. Then, the U-shaped groove 4 of the longitudinal claw 3 engages with the cover buckle 37, pressing the connector 38 of the cover buckle 37 into the instrument, thus completing the installation of the cover 35. The U-shaped groove 4 also has a limiting function for the cover buckle 37, preventing the cover buckle 37 from tilting or falling off during pressing. The flat claws 2 and the longitudinal claw 3 can be driven by a cylinder or other driving device. This scheme can complete the installation of the cover 35 onto the instrument.

[0027] A support frame 21 with a cover mounting claw 1 is located between the first rotating disk 10 and the second rotating disk 11. The first rotating disk 10 and the second rotating disk 11 are respectively provided with four cover platforms 12 and instrument platforms 13 for holding the cover 35 and the instrument, respectively. The cover platforms 12 and instrument platforms 13 are evenly distributed on the outer edges of the first rotating disk 10 and the second rotating disk 11. Figure 1 As shown, the first rotating disk 10 moves clockwise. The four watch cover platforms 12 along the clockwise direction of the first rotating disk 10 are provided with a watch cover feeding device 15, a watch cover buckle feeding device 16, a labeling device 17, and a watch cover mounting claw 1 in sequence. Since four processes need to be completed on the first rotating disk 10, the first rotating disk 10 rotates four times as one cycle.

[0028] like Figure 1 and Figure 6As shown, the watch cover feeding device 15 includes a watch cover gripper 18 and a conveyor belt 40. At the output end of the conveyor belt 40, there is also a pusher 41 and a partition plate 42. The watch cover 35 is transferred to the conveyor belt 40 via a vibrating plate (not shown in the figure) and then to the output end of the conveyor belt 40. The partition plate 42 moves away from the first rotating disk 10, so that the watch cover 35 enters the pusher 41 from the conveyor belt 40. A detection sensor is provided above the pusher 41. After the sensor detects that there is a watch cover 35 on the pusher 41, the partition plate 42 moves towards the first rotating disk 10 to prevent subsequent watch covers 35 from entering the pusher 41. After the first rotating disk 10 rotates once, the watch cover gripper 18 transports the watch cover 35 from the pusher 41 to the watch cover platform 12. After the sensor detects that the watch cover 35 on the pusher 41 has been transferred, the partition plate 42 continues the above action to allow the watch cover 35 to enter the pusher 41.

[0029] like Figure 1 and Figure 4 As shown, the watch cover buckle feeding device 16 includes a vibratory plate 9 and a conveying trough 19. A watch cover buckle mounting mechanism 5 is provided at the output end of the conveying trough 19. The watch cover buckle mounting mechanism 5 includes a first clamping block 6, a second clamping block 7 and a push rod 8. When the watch cover 35 is transported to the second station, namely the watch cover latch feeding device 16, and the watch cover latch 37 is also transported to the output end of the conveyor trough 19, the structure at the output end of the conveyor trough 19, from top to bottom, is: the first pressing block 6 and the push rod 8, the watch cover 35, the through hole 14 of the watch cover platform, the through hole 14 of the first rotating disk, the watch cover latch 37, and the second pressing block 7. Then, the first pressing block 6 moves downward first, pressing down on the watch cover 35 to prevent the watch cover 35 from changing position. Then, the second pressing block 7 moves upward, pressing the watch cover latch 37 into the mounting groove of the watch cover 35 through the through hole 14 on the first rotating disk 10 and the watch cover platform 12. Then, the second pressing block 7 resets, and the watch cover latch 37 is connected. The head 38 is arranged radially along the cover 35. Then, the push rod 8 begins to move downward, pushing the connecting head 38 of the cover latch 37 to rotate, so that the connecting head 38 is perpendicular to the cover 35 and located at the bottom. Finally, the first clamping block 6 is reset, and the first rotating disk 10 rotates once to continue to the next process. When the cover latch 37 is transported to the transport trough 19 under the action of the vibrating disk 9, the snap-fit ​​groove 39 of the cover latch 37 is arranged upward and corresponds to the connecting rod 36 of the cover 35, and the connecting head 38 of the cover latch 37 is arranged radially along the first rotating disk 10 and outward from the first rotating disk 10. The cover 35 is transported to the labeling device 17, and the labeling process of the cover 35 is completed by the telescopic movement of a labeling rod. After the labeling process is completed, the cover 35 moves to the position of the cover mounting claw 1, and the cover mounting claw 1 transports the cover 35 to the instrument, completing the installation of the cover 35.

[0030] like Figure 1As shown, the second rotating disk 11 moves clockwise. The two symmetrical instrument platforms 13 on the second rotating disk 11 are equipped with an instrument loading mechanism 22 and an instrument unloading mechanism 23 at corresponding positions. The instrument platform 13 between the instrument loading mechanism 22 and the instrument unloading mechanism 23 corresponds to the cover platform 12 on the first rotating disk 10 at the position of the cover mounting claw 1. A second adjustment mechanism 27 is provided between the position of this instrument platform 13 and the instrument loading mechanism 22. The second adjustment mechanism 27 includes an adjustment frame and an adjustment claw that is slidably connected to the adjustment frame along the radial direction of the second rotating disk 11. As shown in the figure, the second adjustment mechanism 27 is located between the instrument loading mechanism 22 and the instrument platform 13 and the instrument cover mounting jaw 1, corresponding to the instrument table 13 and the instrument cover platform 12. Thus, the second rotating disk 11 rotates eight times in one cycle, and the rotation speed is relatively slow. On the one hand, because the instrument has a large mass, the position of the instrument may change due to inertia when the second rotating disk 11 rotates. The slower rotation speed of the second rotating disk 11 helps to prevent the instrument position from changing and improves the assembly accuracy. On the other hand, it makes the structure between each station compact and saves space. When the instrument is delivered to the position, the adjustment jaw slides radially along the second rotating disk 11 to the position of the instrument. Then, the adjustment jaw gently clamps the instrument to calibrate its position. Then, the adjustment jaw resets, and the instrument enters the next station under the action of the second rotating disk 11. The instrument loading mechanism 22 is equipped with an instrument gripper 24, and the instrument unloading mechanism 23 is equipped with an instrument rotating gripper 25. The instrument gripper 24 can pick up the instrument and place it onto the instrument table 13 of the second rotating disk 11. Since the instruments are arranged neatly, their position changes at a certain angle after moving from the second rotating disk 11 to the instrument unloading mechanism 23. Therefore, the gripper on the instrument unloading mechanism 23 is rotatable to recalibrate the angle of the instrument. Both the instrument gripper 24 and the instrument rotating gripper 25 are driven by cylinders or other mechanisms, and both use a slider and slide rail structure to complete the input and output of the instrument.

[0031] A position calibration mechanism also needs to be installed at the first rotating disk position, such as... Figure 1 As shown, a first adjustment mechanism 26 is provided between the watch cover clip feeding device 16 and the labeling device 17. The first adjustment mechanism 26 includes a calibration rod 28 and an adjustment seat 30. The calibration rod 28 is located at the bottom of the first rotating disk 10 and can extend and retract along the vertical direction of the first rotating disk 10. After the calibration rod 28 abuts against the first rotating disk 10, it is engaged at the bottom of the first rotating disk 10 to adjust the position of the first rotating disk 10 and ensure that the watch cover 35 is in the correct position. The calibration rod 28 can be mounted on a slider 33 for extension and retraction, and the slider 33 is mounted on the adjustment seat 30. A buffer block 29 is also provided in the direction of slider movement to limit and buffer the calibration rod 28.
