Description

Technical Field

[0001] The invention relates to the technical field of movement installation, and in particular to a movement free positioning device for water meter installation. Background Art

[0002] The water meter movement installation structure is a series of mechanical structure combinations used to firmly install the water meter movement in the water meter housing and ensure its normal operation. The main structural parts are: the meter housing connection structure, which usually adopts threaded connection, flange connection or clamp connection to tightly connect the movement with the water meter housing to ensure sealing performance and prevent water leakage; the positioning device, which is generally composed of positioning grooves, positioning protrusions or positioning pins, can accurately determine the position of the movement in the meter housing, ensure the relative position accuracy between various components, and enable the water flow to flow through various measuring components of the movement according to the designed path; the fixing device, which is commonly screws, buckles or elastic clips, firmly fixes the movement in the meter housing to avoid displacement or shaking under the impact of water flow, vibration or external environment; the sealing structure, which mostly adopts rubber sealing rings, sealing pads and other components, is installed at the connection between the movement and the meter housing to prevent water from seeping out from the gap between the movement and the meter housing, and at the same time prevents external dust, debris, etc. from entering the movement and affecting the normal operation of the water meter.

[0003] The horizontal angle of the movement installation determines the consistency and stability of the water meter's measurement performance. If the installation horizontal angle is too different, the overall measurement performance of the water meter will not meet national standards. The consistency and stability of the movement installation horizontal angle control determines the consistency of the water meter's product performance and the product's qualification rate.

[0004] The current installation method in the domestic industry is to install the movement into the water meter housing by naked eyes and manual operation, which has the following disadvantages:

[0005] The movement installation angle deviation range is large (within ±3° of the center line angle of the water meter housing), resulting in poor stability and consistency of the water meter measurement performance;

[0006] The installation efficiency is low and the installation time of a single water meter is long;

[0007] It is impossible to achieve continuous, stable and automatic movement installation;

[0008] During operation, employees rely on their naked eyes to inspect the appearance quality of the movement, which cannot avoid interference from human factors in movement inspection;

[0009] Lack of data records of real-time water meter movement installation;

[0010] It is not possible to quickly achieve movement installation at any movement installation angle;

[0011] Therefore, we make improvements on this and propose a movement free positioning device for water meter installation. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0059] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the invention claimed for protection, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0060] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0061] like Figure 1 As shown, this embodiment proposes a free positioning device for the movement of the water meter installation, including a movement positioning support frame 1, the rear end of the movement positioning support frame 1 is provided with a loading assembly 11 and a unloading assembly 12, the loading assembly 11 and the unloading assembly 12 are respectively provided with a collection tray 4, the collection tray 4 in the loading assembly 11 is provided with a movement 3 to be absorbed, the front end of the movement positioning support frame 1 is provided with a production line 10, and the upper end of the production line 10 is provided with a carrier assembly 8 and a meter body 14.

[0062] like Figure 5-Figure 10 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the watch mouth leveling assembly 7 is used for stable placement between the movement 3 to be absorbed and the watch case 14, and the watch mouth leveling assembly 7 includes a carrier lifting plate 71, a horizontal fixing plate 73 and a shift limiting wheel 75. The lower end of the carrier lifting plate 71 is provided with a lifting cylinder 72 and a telescopic support 74, the upper end of the horizontal fixing plate 73 is provided with a leveling block 79, the outer end of the shift limiting wheel 75 contacts the outer side of the carrier assembly 8, the outer end of the shift limiting wheel 75 is provided with a shift limiting seat 76, the lower end of the shift limiting seat 76 is provided with a shift limiting shaft 77, and the lower end of the shift limiting shaft 77 is provided with a shift limiting cylinder 78.

[0063] The lower end of the carrier lifting plate 71 is movably connected through the lifting cylinder 72 and the telescopic support member 74. A fixed plate is fixed to the lower end of the lifting cylinder 72, and the fixed plate is fixed on the movement positioning support frame 1. An L-shaped piece is fixed to one end of the fixed plate. The upper end of the L-shaped piece is movably connected to the shift limiting cylinder 78. The movable end of the shift limiting cylinder 78 moves on the lower end inner surface of the shift limiting seat 76. The lower end of the shift limiting seat 76 rotates along the shift limiting shaft 77. The upper end of the shift limiting seat 76 is movably connected to the shift limiting wheel 75.

[0064] The carrier assembly 8 includes a carrier body 81, the upper end of which is provided with two groups of carrier hanging ears 82 and two groups of carrier sliding blocks 83, the outer ends of the two groups of carrier sliding blocks 83 are respectively connected with elastic structures 84, the water inlet and outlet ends of the watch shell 14 are respectively movably engaged with the two groups of carrier hanging ears 82, and the front and rear ends of the watch shell 14 are respectively movably connected with the two groups of carrier sliding blocks 83.

[0065] Features: By utilizing the fact that the water meter openings are at the same level, a horizontal fixing plate 73 (different fixing plates can be adjusted according to different diameters) is installed on the upper part of the water meter opening as a horizontal standard for the opening positioning. The water meter housing 14 is lifted from bottom to top as a whole through the lower lifting plate to achieve the accumulation and compaction of the water meter opening and the top of the horizontal fixing plate 73, thereby achieving the consistency of the water meter opening and the horizontal fixing plate 73.

[0066] Advantage 1: Through simple components, the water meter mouth and the Z-axis of the movement suction device are perpendicular, which avoids the non-perpendicular state of the mouth and the movement installation direction caused by the tilt of the meter case 14 (because the difference between the outer diameter of the movement and the inner diameter of the mouth is ≤1mm, the tilt of the mouth will cause the movement to collide with the inner wall of the case 14 or the movement to collide with the mouth during installation, which will lead to the failure of movement installation. The difficulty of whether the movement can be installed normally lies here), ensuring that the movement can be accurately installed in the case 14.

[0067] Advantage 2: It replaces the process of manually sensing and adjusting the watch case 14 through the naked eye and manual operation;

[0068] Advantage 3: The assembly can adapt to watch housings 14 of different calibers by adjusting the size of the middle opening of the horizontal fixing plate 73. The structure is simple and easy to adjust and adapt to different watch housings 14.

[0069] like Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, it further includes a core suction component 2, which is used for sucking and moving the core 3 to be sucked, and the core suction component 2 includes a core suction z-axis servo module 23, a core suction x-axis motion module 27 and a core suction Y-axis motion module 28. The lower end of the core suction z-axis servo module 23 is provided with a core suction camera 21, a suction plate 25 and a core suction light source 24, the inner end of the suction plate 25 is provided with a suction telescopic member 26, and the lower end of the suction telescopic member 26 is provided with a vacuum suction head 22.

[0070] An R-axis servo motor for rotation is provided on the suction core z-axis servo module 23 for rotating the suction plate 25 , and the R-axis servo motor and the suction plate 25 are connected to each other.

[0071] The image information taken by the suction core camera 21 is converted into the plane coordinates (X / Y) of the set direction (usually the horizontal line of the carrier streamline direction) and the plane coordinate distance of the set center point (usually the center point of the suction cup) through its own camera recognition software;

[0072] For example, find two circles on the movement, connect the centers of the two circles with a virtual straight line, and there is an angle between the line connecting the two centers and the set center line, so as to calibrate the angle information of the movement relative to the set direction. Similarly, the relative position of the center point of the line connecting the two centers of the circle and the set center point will also be obtained.

[0073] The software outputs the acquired angle and relative distance information to the PLC (built-in device driver). The PLC (built-in device driver) controls the servo driver, which controls the servo motor to drive the motion module to move to the corresponding plane coordinate position. Synchronously, the PLC (built-in device driver) controls the servo driver to adjust the suction direction of the suction cup through the servo motor to suck the movement according to the freely set angle.

[0074] The core Y-axis motion module 28 is fixed on the upper end of the core positioning support frame 1 , the core X-axis motion module 27 slides on the upper end of the core Y-axis motion module 28 , and the core Z-axis servo module 23 slides on the upper end of the core X-axis motion module 27 .

[0075] The wick camera 21 is fixed to the lower end of the wick z-axis servo module 23 , the outer end of the wick camera 21 is fixedly connected to the wick light source 24 , and the suction plate 25 is fixed to the other end of the wick z-axis servo module 23 .

[0076] Two groups of dial positioning columns are fixed to the lower end of the suction plate 25 , a suction groove is provided at the inner end of the suction plate 25 , a suction telescopic member 26 is provided at the inner end of the suction groove, and a vacuum suction head 22 is provided at the lower end of the suction telescopic member 26 .

[0077] First: the movement suction component 2 can absorb various types of movements within the caliber of DN15-DN100;

[0078] Advantage 1: The movement suction component 2 has a wide range of applicability and can complete suction for movements of different sizes, types and functions;

[0079] Advantage 2: It replaces the process of manual identification by naked eyes and grabbing the movement by hand;

[0080] Second: the movement suction component 2 can absorb the movement placed arbitrarily in the horizontal direction in the extraction tray 4;

[0081] Advantages: No need to place the movements in a uniform direction, which greatly reduces the intensity and difficulty of employees loading the movements into the tray 4, and greatly increases the speed of loading the movements into the tray 4;

[0082] Thirdly, the core suction assembly 2 is adjustable up and down in the Z-axis direction, and the core vacuum suction head 22 has a suction margin in the Z-axis direction, which can adapt to the height difference of the core at different positions on the same extraction plate 4;

[0083] Advantages: It greatly reduces the requirements for assembling the plate 4 of the movement, reduces the investment cost of the plate 4, and also reduces the labor intensity of employees. To ensure that the movements at different positions in the plate 4 are at the same level, the plate 4 must be made of high-strength metal.

[0084] like Fig.11 As shown, as a preferred embodiment, on the basis of the above-mentioned method, it further includes: a movement side view detection component 5, the movement side view detection component 5 includes a side view camera 51 and a side view support frame 52, the side view support frame 52 is fixed on the movement positioning support frame 1, the side view camera 51 is fixed on the upper end of the side view support frame 52, and the camera mouth end of the side view camera 51 is provided with a light source.

[0085] In production and assembly, the main types of movement defects are: movement component detachment and component missing. The device includes a side-view camera 51 and a side-view support frame 52 through a movement detection component. The component is connected to a camera recognition software known to those skilled in the art. Standard reference templates are made by taking photos of qualified movements and stored in the system. In the production process, different types of movement standard reference templates are selected by the program to identify the defects of different types of movements.

[0086] In one embodiment, the filter at the bottom of the movement falls off due to the phenomenon of transportation. The device uses the side-view camera 51 to take pictures to obtain the image information of the movement. By comparing with the standard reference template of the movement stored in the system, the phenomenon of the filter falling off can be found, and the movement will be judged as a defective product and placed in the defective product area to prevent the unqualified movement from being installed in the watch case;

[0087] Another embodiment: if there is a hole on the movement housing, the device uses the side-view camera 51 to take a picture to obtain the movement image information, and by comparing it with the movement standard reference template stored in the system, it can be found that there is a hole in the housing, so that it will be judged as a defective product and put into the defective product area to prevent the unqualified movement from being installed in the watch case;

[0088] Feature 1: The movement side view detection component 5 uses the side view camera 51 to shoot the side of the movement sucked by the movement suction component 2 at a set angle of 0-360°, and can complete the detection and judgment of whether there are missing components in the movement, whether there are structural defects in the movement, etc.;

[0089] Advantages: Shooting at a set angle can significantly reduce the number of movements with missing components or obvious defects flowing into the next assembly link, replacing the manual identification process with the naked eye;

[0090] Feature 2: If the visual system detects that the movement does not meet the set requirements, the movement is judged as unqualified and placed in a defective product recycling box.

[0091] Advantages: The camera recognition software and the movement suction component 2 are used together to complete the detection of the movement quality, which avoids the error of manual visual judgment on the one hand, and avoids the situation where a defective movement is artificially installed into the watch case 14 on the other hand.

[0092] like Fig.12 As shown, as a preferred embodiment, on the basis of the above-mentioned method, it further includes: a downward-looking coordinate acquisition component 6 for the case, the downward-looking coordinate acquisition component 6 for the case includes a downward-looking camera 61 and a downward-looking X-axis servo module 62, the downward-looking X-axis servo module 62 is fixed on the movement positioning support frame 1, the upper end of the downward-looking X-axis servo module 62 is slidably provided with a downward-looking support frame, the upper end of the downward-looking support frame is provided with a downward-looking camera 61, and the camera mouth end of the downward-looking camera 61 is provided with a light source.

[0093] Feature 1: The downward-looking camera 61 and the downward-looking X-axis servo module 62 are used to take a picture of the surface of the meter housing 14 after the surface surface leveling has been completed and obtain the X-axis and Y-axis coordinates, which can adapt to the problem of poor X-axis and Y-axis repeatability of the surface of the water meter caused by the large size difference of the water meter housing 14.

[0094] Advantage 1: Taking photos through the X-axis and Y-axis to obtain the X-axis and Y-axis coordinates is not affected by the size difference of the water meter shell, and can also meet the coordinate acquisition requirements of water meters of different sizes, greatly improving the adaptability of this component to water meter types;

[0095] Advantage 2: It replaces the process of manually perceiving the opening of the watch case 14 with the naked eye;

[0096] Feature 2: The process of taking photos of the component to obtain the X-axis and Y-axis coordinates of the watch case 14 is synchronized with the movement suction and side view photo detection;

[0097] Advantages: Parallel actions significantly shorten the inspection of the entire movement installation.

[0098] like Fig.13 As shown, as a preferred embodiment, based on the above method, it further includes: a movement photographing detection component 9 and a material transfer component 13, the movement photographing detection component 9 is used for detection after the movement is assembled, and the material transfer component 13 is used for moving the extraction plate 4.

[0099] The core suction camera 21, side view camera 51 and downward view camera 61 in the device are all connected to camera recognition software known to those skilled in the art, which respectively detect the movement before, during and after installation to ensure that there will be no defects or unstable installation during the installation of the movement.

[0100] When using this application:

[0101] First, the suction core camera 21 takes a picture and transmits the data coordinates to the servo motor, which drives the servo motor to rotate and adjust the horizontal angle of the suction plate 25. The suction core Z-axis servo module drops to a certain height, and drives the vacuum suction head 22 in the suction core to start vacuum suction, thereby sucking the core 3 to be sucked in the extraction plate 4;

[0102] Secondly, the movement suction component 2 transports the sucked movement to the shooting position of the side-view camera 51, transmits a shooting signal to the side-view camera 51, and starts shooting at the same time. The servo motor of the movement suction component 2 rotates to a set angle, and the side-view camera 51 completes the shooting and outputs the detection result. This step can detect whether the movement is fully assembled, and rotate the horizontal rotation distance of the movement to facilitate mutual installation with the watch case 14;

[0103] Furthermore, the carrier body 81 moves to the carrier lifting plate 71 through the production line 10, and gives the lifting cylinder 72 a signal of being in place. The lifting cylinder 72 lifts the carrier lifting plate 71, driving the carrier lifting plate 71 to move upward, and the surface opening of the watch shell 14 fits with the horizontal fixing plate 73; (before this, the leveling block 79 on the horizontal fixing plate 73 moves inward to the size of the diameter of the currently assembled watch shell 14, so that the upper end of the watch shell 14 can be stuck, to prevent the change in the distance of the watch shell 14 moving upward when the carrier lifting plate 71 is lifted; secondly, before this, the shift limiting wheel 75 located at the outer end of the carrier lifting plate 71 adjusts the angle of the shift limiting seat 76 through the shift limiting cylinder 78, so that the shift limiting wheel 75 fits the outer end of the carrier body 81, so that the up and down movement of the carrier body 81 is stable).

[0104] Finally, the downward-looking coordinate acquisition component 6 of the watch case transmits a movement signal to the downward-looking X-axis servo module 62 - the downward-looking X-axis servo module 62 moves to the downward-looking photo-taking position and gives an in-position signal, the downward-looking camera 61 takes a photo and outputs the coordinate information of the surface opening of the watch case 14, and the movement suction component 2 obtains the coordinate information of the surface opening of the watch case 14, and according to the suction core z-axis servo module 23, the suction core x-axis motion module 27 and the suction core Y-axis motion module 28, the sucked movement is loaded into the water meter case 14.

[0105] Step 1: The core suction component 2 uses the core suction camera 21 to photograph the core in the extraction tray 4 to obtain the plane X-axis and Y-axis coordinates of the core setting mark;

[0106] Step 2: The core suction component 2 controls the X-axis, Y-axis, Z-axis and R-axis through the servo motor to adjust to the X-axis and Y-axis coordinate positions given by the core suction camera 21, and sucks the core downward;

[0107] Step 3: The movement suction component 2 moves to the movement side view detection component 5 to take pictures at any set rotation angle and determine whether the movement meets the set quality requirements (the rotation angle can be adjusted from 0 to 360 degrees to complete the complete appearance inspection of the movement side, and the quality requirements can be set in advance);

[0108] Step 4: The water meter shell is input into the water meter shell surface leveling assembly 7 through the carrier for leveling (leveling principle: by installing a horizontal fixing plate 73 on the upper part, the entire water meter shell is lifted by a cylinder at the lower part, and the surface of the water meter shell is in the same horizontal plane, and the surface of the water meter shell is parallel to the horizontal fixing plate 73 through the upper and lower squeezing forces);

[0109] Step 5: The housing bottom-view coordinate acquisition component 6 takes a photo of the leveled water meter housing through the bottom-view camera 61 to acquire the X-axis and Y-axis coordinates and synchronously transmits them to the movement absorption component 22;

[0110] Step 6: The movement suction component 2 adjusts the X-axis and Y-axis coordinates of the water meter housing obtained by the lower-view coordinate acquisition component 6 according to the housing, and adjusts the X-axis and Y-axis installation coordinates of the movement through the R-axis servo to meet the set movement installation water meter angle (the movement installation angle can be set arbitrarily within 360° according to needs);

[0111] Step 7: The movement suction component 2 controls the X-axis, Y-axis and Z-axis of the movement with adjusted installation coordinates into the water meter case through the servo motor and returns to the safe waiting position.
