Description

Technical Field

[0001] The utility model belongs to the field of gas meter component production, and specifically relates to an integrated gas meter metering shell manufacturing system. Background Art

[0002] The metering shell is one of the important components of the diaphragm gas meter and is usually produced by stamping. The gas meter movement and the metering shell have a sealing surface. After the main body is formed, in order to further improve the sealing of the membrane cavity, a sealing strip will be set on the inside of the metering shell. The traditional method is to directly bond the finished sealing ring, or transfer the metering shell to the gluing equipment for on-site gluing to form an annular sealing strip. The operating procedures of both processes increase the transportation and independent feeding steps of the metering shell, which greatly reduces the production efficiency and increases the site space occupation, which is not conducive to the rapid mass production of the metering shell. Utility Model Content

[0062] The batch glue coating device 200 includes a plurality of glue coating conveying lines 210 and a glue coating mechanism 220 arranged corresponding to the glue coating conveying lines 210 .

[0063] The transfer module 300 is located between the metering shell punching machine 100 and the batch gluing device 200, and includes a transfer conveyor line A310, a transfer conveyor line B320 and a feeding mechanism 330. A flipping mechanism 340 is provided between the transfer conveyor line A310 and the transfer conveyor line B320. Specifically, the transfer conveyor line B320 has a first material receiving end and a first material discharging end, and the transfer conveyor line B320 has a second material receiving end, which protrudes to the outside of the first material discharging end. The flipping mechanism 340 is provided between the first material discharging end and the second material receiving end. The transfer conveyor line A310 is used to receive the metering shells delivered from the discharge port 110. After being flipped by the flipping mechanism 340, the metering shells enter the transfer conveyor line B320 with the concave surface facing upwards. The feeding mechanism 330 delivers the metering shells on the transfer conveyor line B320 to the gluing conveyor line 210.

[0064] Key References Figures 1 to 5 The transfer module 300 mainly includes a workbench A350. The transfer conveyor line A310 and the transfer conveyor line B320 are both horizontally mounted on the workbench A350 through a frame A351. In the present embodiment, both are belt conveyor lines, and the transfer conveyor line B320 is located directly below the transfer conveyor line A310. The first discharge end of the transfer conveyor line A310 is a slope section 311, and the flipping mechanism 340 is arranged corresponding to the slope section 311.

[0065] As shown in the figure, the flipping mechanism 340 includes a stop plate 341 and at least one retaining block 342, wherein the stop plate 341 corresponds to the lower end of the ramp section 311, and the vertical distance between the stop plate 341 and its end is less than half the width of the metering shell and greater than the thickness of the metering shell, at least one retaining block 342 corresponds to the upper end of the ramp section 311, and is rotatably arranged directly above the upper end of the ramp section 311, and the vertical distance between the stop plate 341 and the upper end of the ramp section 311 is less than the thickness of the metering shell.

[0066] Specifically, the top of the frame A351 has a fixed support frame 352, which is arranged along the width direction of the transfer conveyor line A310 and is located above the transfer conveyor line A310. The retaining block 342 is suspended on the support frame 352 by a hook 353. The hook 353 can rotate relative to the support frame 352. At the same time, the retaining block 342 can rotate relative to the hook 352. The two relative rotation planes are parallel to each other, and the rotation planes are perpendicular to the conveying surface of the transfer conveyor line A310. In this embodiment, two retaining blocks 342 are provided, one of which is arranged corresponding to the upper end of the ramp section 311, and the other is arranged corresponding to the middle of the ramp section 311.

[0067] The stop plate 341 is located just in front of the lower end of the slope section 311, and the end of the transfer conveyor line B320 corresponding to the slope section 311 is relatively longer, ensuring that the metering shell falling from the gap between the stop plate 341 and the slope section 311 can fall on the transfer conveyor line B320, and the transfer conveyor line B320 is in opposite conveying directions to the transfer conveyor line A310, so that the metering shell (concave surface facing downward) transported from its horizontal section into the slope section 311 on the transfer conveyor line A310 is restricted by the retaining block 342 and can basically maintain a fit posture with the conveying surface, and then affected by the stop plate 341, its lower side in the length direction first contacts the transfer conveyor line B320 at a slightly inclined angle, and affected by the inertia of the transfer conveyor line B320, its upper side falls backwards, and at this time the concave surface of the metering shell faces upward, that is, the metering shell is flipped.

[0068] In this embodiment, the feeding mechanism 330 is located on one side of the width direction of the transfer conveyor line B320, and mainly includes a base plate 331, a mounting frame 332 supported on the base plate 331, a feeding frame 333 movably arranged on the mounting frame 332, and a feeding cylinder 334 connected to the feeding frame 333, wherein the feeding frame 333 has a pushing plate 335 arranged perpendicular to the length direction of the transfer conveyor line B320, and the feeding cylinder 334 is used to drive the feeding frame 333 to approach or move away from the transfer conveyor line B320. When installed, the feeding mechanism 330 is fixed on the workbench A350 as a whole through the base plate 331.

[0069] In specific implementation, the mounting frame 332 is movably supported on the base plate 331, and a vertical guide structure is provided between the two. A height adjustment cylinder 336 is provided on the base plate 331, and its piston rod faces upward and is connected to the mounting frame 332, so that the overall height of the mounting frame 332 can be adjusted by the height adjustment cylinder 336.

[0070] There is a horizontal guide structure between the feeding rack 333 and the mounting rack, and the guiding direction is perpendicular to the conveying direction of the transfer conveyor line B320. The push plates 335 on the feeding rack 333 are distributed at intervals. At the same time, a feed alignment plate 337 and a plurality of feed sensing seats 338 are provided on the frame A351 corresponding to the transfer conveyor line B320. The feed alignment plate 337 is mounted on the transfer conveyor line B320 and is relatively far away from the slope section 311. The feed sensing seats 338 and the push plates 335 are arranged one by one in correspondence. The feed alignment plate 337 and the plurality of feed sensing seats 338 are provided with material sensors for detecting whether there is a metering shell at the corresponding position on the transfer conveyor line B320. When the metering shells are transferred to the transfer conveyor line B320 in turn, when the first metering shell is against the feed alignment plate 337, there is basically a metering shell facing the push plate 335, so that the facing metering shell can be pushed to the other side of the transfer conveyor line B320 through the push plate 335.

[0071] Key References Figures 1 to 17 The batch glue coating device 200 of the present application mainly includes a workbench B270, and a material guide rack 280, a glue coating conveyor line 210 and a glue coating mechanism 220 arranged on the workbench B270. As shown in the figure, the material guide rack 280 has a material guide trough 281 arranged one-to-one corresponding to the glue coating conveyor line 210, and the material guide trough 281 has symmetrically arranged steps on both inner sides opposite to the length direction, which can allow the metering shell to be suspended and supported in the material guide trough 281.

[0072] The material guide rack 280 is divided into a material preparation station, a waiting station, a gluing station and a material picking station along its length direction. The gluing conveyor line 210 is located below the material guide rack 280 and covers the length area of ​​the material preparation station and the waiting station. The gluing mechanism 220 is arranged corresponding to the gluing station. A station switching mechanism 230 is arranged below the material guide rack 280. The station switching mechanism 230 is used to move the metering shells at the waiting station and the gluing station forward one station in sequence, that is, the metering shell is in the material guide trough 281, and is moved from the entrance end of the material preparation station to the waiting station through the glue conveyor line 210, and the metering shell at the waiting station 230 can be moved to the gluing station through the station switching mechanism 230, and the metering shell at the gluing station can be moved to the material picking station.

[0073] The batch gluing device 200 includes a positioning mechanism 240 arranged at a corresponding gluing station, and each material guide trough 281 has a corresponding positioning mechanism 240. The positioning mechanism includes a lifting cylinder 241 located below the material guide trough 281. The piston rod of the lifting cylinder 241 faces upward, and its top has a horizontally arranged top plate 242. The width of the top plate 242 is less than or equal to the width of the material guide trough 281. The material guide frame 280 has at least two diagonally distributed positioning pins 243. The distribution position of the positioning pins 243 is adapted to the position of the through holes on the outer edge of the metering shell. When the metering shell is in the gluing station, the lifting cylinder 241 works to lift the metering shell through the top plate 242. At the same time, the positioning pins 243 are inserted into the corresponding through holes of the metering shell to support and position the metering shell, thereby ensuring the stability of the gluing process and improving the gluing quality.

[0074] In this embodiment, the two actions of moving the metering shell of the waiting station 230 to the gluing station and the metering shell of the gluing station to the material taking station are synchronously completed by the station switching mechanism 230, as shown in the figure, including a mounting plate 231 located below the material guide frame 280 and spanning all the material guide grooves 281, and a station switching drive component for driving the mounting plate 231 to slide horizontally and lift vertically along the length direction of the material guide groove 281. The station switching drive component mainly includes a bottom plate 232. When installed, the station switching mechanism 230 is integrally connected to the bottom plate 232. 232 is fixed on the workbench B270, and the two sides of the base plate 232 are provided with symmetrically arranged vertical support plates 233. The vertical support plate 233 is provided with a slide 234 which is vertically slidably matched therewith, and a lifting cylinder 235 for driving the slide 234 to move vertically. At the same time, the left and right sides of the mounting plate 231 are slidably matched with the slide 234 through a horizontal guide structure, and the guide direction is parallel to the material guide groove 281, and a horizontal switching cylinder 236 is configured to drive the mounting plate 231 to slide along the direction of the material guide groove 281.

[0075] The mounting plate 231 has a pushing assembly corresponding to the material guide groove 281, and the pushing assembly is mainly used to push the metering shell forward. In this embodiment, the pushing assembly includes a pushing piece A2310, a pushing piece B2311 and a pushing piece C2312 which are sequentially arranged in the direction away from the gluing conveyor line 210, wherein the horizontal distance between the pushing piece A2310 and the pushing piece B2311 is adapted to the length of the metering shell, thereby enabling better rapid and accurate positioning of the metering shell at the gluing station.

[0076] It should be noted that, in the present embodiment, in order to make full use of the height space and improve the compactness and installation convenience of the overall structure, the lifting cylinder 241 is directly supported on the base plate 232 through the support rod 244, and the lifting cylinder 241 is located above the base plate 232. Correspondingly, there are strip avoidance holes 2313 corresponding to the support rods on the mounting plate 231, and the strip avoidance holes 2313 are arranged along the length direction of the material guide groove 281, so as not to hinder the forward and backward sliding of the base plate 232. At the same time, the pushing piece B2311 adopts a rod-like structure or a frame structure arranged in groups. During the forward and backward sliding process, it is not blocked by the lifting cylinder 241, but the width is less than or equal to the width of the metering shell.

[0077] refer to Figures 6 to 11 The glue coating mechanism 220 mainly includes a glue gun moving unit and a glue quantity control unit, wherein the glue gun moving unit includes a glue gun fixing plate 221, and a three-axis gantry module 222 for controlling the moving trajectory of the glue gun fixing plate 221, the three-axis gantry module 222 is fixedly supported on the workbench B270, and the glue gun fixing plate 221 has a glue gun 2210 arranged one-to-one corresponding to the material guide groove 281, and the three-axis gantry module 222 is used to control and drive the glue gun 2210 to perform lifting, translation and left and right movement, that is, to complete the movement of the preset trajectory, and at the same time, the glue gun 2210 sprays glue to complete the gluing operation.

[0078] The glue quantity control unit mainly includes a glue supply machine 223, a pressure stabilizing valve 224 and a pressure regulating valve A225. The glue outlet of the glue supply machine 223 is connected to the pressure stabilizing chamber of the pressure stabilizing valve 224 through a pipeline, the air outlet end of the pressure regulating valve A225 is connected to the air inlet of the pressure stabilizing valve 224 through a pipeline, the glue outlet of the pressure stabilizing valve 224 is connected to the chamber of the glue gun 2210 through a pipeline, and the regulating valve A225 is connected to the high-pressure air source. By adjusting the pressure of the regulating valve A225, the amount of glue entering the chamber of the glue gun 2210 can be controlled.

[0079] On this basis, in this embodiment, the glue gun 2210 is connected to a single pressure control pipeline (not shown in the figure), which is connected to the air source. A glue stop valve structure is usually adopted to control the opening and closing size of the glue stop valve through the single pressure control pipeline, thereby further finely controlling the glue output.

[0080] Combination Figures 12 to 17 The glue coating device 200 further includes a stop mechanism A250 corresponding to the end of the material preparation station, and a stop mechanism B260 corresponding to the end of the waiting station. As shown in the figure, the stop mechanism A250 includes a gantry A251 supported on a workbench B270, the gantry A251 is arranged across the top of the material guide frame 280, and has a stop cylinder A252 arranged one-to-one with the material guide groove 281, and the piston rod of the stop cylinder A252 faces downward and is connected to a stopper A253.

[0081] The structure of the stop mechanism B260 is similar to that of the stop mechanism A250, and mainly includes a gantry B261. The difference is that the gantry B261 adopts an integral lifting structure. As shown in the figure, the two ends of its horizontal plate are slidably matched with the vertical plate, and are equipped with a stop cylinder B262. The stop cylinder B262 can drive the horizontal plate 264 to rise and fall. At the same time, the horizontal plate has a baffle B263 extending downward. At the same time, a detection sensor 265 is arranged on the gantry B261. The detection sensor 265 is arranged in a one-to-one correspondence with the material guide trough 281, that is, it is arranged in a one-to-one correspondence with the baffle B263, and is located upstream of the incoming material of the baffle B263, so as to detect whether there is a metering shell at the corresponding waiting station. In this embodiment, a gap is left between the waiting station and the material preparation station, which can at least allow the pushing piece A2310 to extend. The metering shell in the waiting position is pushed forward. During the working process, when a metering shell is being glued at the gluing position, the piston rod of the stop cylinder B262 is retracted, and the baffle B263 descends to block the metering shell in the waiting position. At the same time, when the detection sensor detects that there is a metering shell at the position, the piston rod of the stop cylinder A252 corresponding to the same material guide trough 281 is extended, and the baffle A253 descends to block the metering shell sent by the glue conveyor line 210, so as to ensure that there is a metering shell at the waiting position in each material guide trough 281, and each metering shell can be aligned horizontally, and then transferred to the gluing position through the position switching mechanism 230, which is conducive to further improving work efficiency, and can avoid the occurrence of empty position operation, thereby greatly improving the overall reliability.

[0082] In the present application, the stop mechanism A250, the stop mechanism B260, the positioning mechanism 240 and the station switching mechanism 230 together constitute the station positioning structure of the metering shell, which can ensure the accuracy of the metering shell at each station on the gluing device, and is conducive to improving the overall operation reliability of the equipment.

At the same time, a special pallet 600 for holding the metering shells is provided, wherein the pallet loading and unloading module mainly includes a pallet supply unit 400 and a pallet transfer unit 500.

[0084] As shown in the figure, the tray 600 includes a plate-like main body 610, and the outer edge of the plate-like main body 610 has a flange 620 bent upward along its thickness direction. The plate-like main body 610 has a plurality of spaced placement holes 611, and the placement holes 611 can allow the metering shell to be placed therein with the concave surface facing upward, while the outer edge of the metering shell is supported on the plate-like main body 610. The bottom of the plate-like main body 610 has at least three evenly distributed support columns 612, and the height of the support columns 612 is greater than the depth of the metering shell. This ensures that when the upper and lower trays 600 are stacked, the metering shell in the upper tray will not contact the metering shell in the lower tray.

[0085] In this embodiment, the plate-like body 610 is generally a rectangular plate-like structure, with grips 613 at both ends in the length direction, and at least two groups of clamping openings 621 symmetrically arranged in pairs in the width direction are provided on the flange 620 .

[0099] refer to Figures 1 to 29 As shown, the integrated gas meter metering shell manufacturing system, when the equipment is assembled, the end of the transfer conveyor line A310 away from the slope section 311 is connected to the discharge port 110, the transfer conveyor line B320 is flush with the gluing conveyor line 210, or slightly higher than the gluing conveyor line 210, the gluing conveyor line 210 and the feeding mechanism 330 are respectively located on both sides of the width direction of the transfer conveyor line B320, the position and number of the pushing plates 335 correspond one by one to the gluing conveyor line 210, the material preparation station, waiting station, gluing station and material picking station are distributed in sequence along the direction away from the transfer module 300, the empty pallet stacking station and the fully loaded pallet stacking station are arranged in parallel, but the station entrance openings are oriented perpendicular to each other to avoid operational interference.

[0100] During the specific implementation process, the metering shell punched by the metering shell punch 100 is sent out with the concave surface facing downward, and after passing through the transfer module 300, it enters the glue conveying line 210 with the concave surface facing upward, and arrives at the glue coating station after passing through the material preparation station and the waiting station in sequence. The glue coating mechanism 220 works to perform the glue coating operation. The sealing rubber ring on the metering shell is generally a rectangular closed loop structure. In this embodiment, in order to improve the quality of the formed rubber ring, during the gluing process, the glue gun 2210 first starts to glue from the middle of the narrow side, and the glue output is controlled by the glue amount control unit. The glue output initially changes linearly and gradually increases, and reaches a stable amount Q within the stroke L. When the glue gun 2210 moves to the initial point, the glue amount changes linearly and gradually decreases, and the glue amount is reduced to zero within the stroke L. This gluing method can greatly reduce the amount of glue being too little or too much at the initial and end moments, thereby preventing the quality of the sealing rubber ring from being reduced, thereby affecting the sealing of the gas meter.

[0101] After the gluing is completed, the metering shell moves to the material picking station, and the metering shell gripper assembly 520 grabs the metering shell at the material picking station and places it on the pallet at the pallet fixed position. When the pallet at the pallet fixed position is full of metering shells, the full-load pallet gripper assembly 530 starts working to grab the pallet and place it at the full-load pallet stacking station.
