Description

Technical Field

[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, a sealing strip will be set on the inside of the metering shell to further improve the sealing of the diaphragm cavity. The traditional practice 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 traditional gluing equipment is not conducive to the gluing operation of batch metering shells, which seriously affects the production efficiency. It is also difficult to cooperate with the stamping die, and the integrated automated production of the metering shell cannot be realized, which also limits the production quality and efficiency of the metering shell.

As shown in the figure, the material guide rack 280 has a material guide trough 281 arranged one-to-one corresponding to the gluing conveyor line 210, one end of the material guide trough 281 is a feed end, and the other end is a discharge end, wherein the end of the feed end is open, and the material guide trough 281 has symmetrically arranged support steps 282 on both inner sides in the length direction, which can support the metering shell in the air in the material guide trough 281.

[0033] The material guide rack 280 is divided into a material preparation station, a waiting station, a gluing station and a material picking station in sequence along the direction away from the feed end. The gluing conveyor line 210 is located below the material guide rack 280, and its conveying length covers the length area of ​​the material preparation station and the waiting station. The gluing mechanism 220 is set corresponding to the gluing station. A station switching mechanism 230 is set 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.

[0034] In this embodiment, a positioning mechanism 240 is further provided at the corresponding gluing station, and each material guide trough 281 has a corresponding positioning mechanism 240. The positioning mechanism 240 includes a lifting cylinder 241 located below the material guide trough 281. The piston rod of the lifting cylinder 241 faces upward, and a horizontally arranged top plate 242 is provided on its top. 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 positions of the positioning pins 243 are adapted to the positions 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.

[0035] 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, the station switching mechanism 230 includes 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, that is, the mounting plate 231 is arranged along the width direction of the material guide frame 280, and the station switching drive component mainly includes a bottom plate 232. When installed, The workstation switching mechanism 230 is fixed on the workbench B270 as a whole through the base plate 232. The base plate 232 has symmetrically arranged vertical support plates 233 on both sides. The vertical support plate 233 has a slide 234 that is vertically slidably matched with it, 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.

[0036] The mounting plate 231 has a pushing assembly arranged one-to-one 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 arranged in sequence along the direction of the far feed end, wherein the horizontal distance between the pushing piece A2310 and the pushing piece B2311 is adapted to the length of the metering shell, thereby better realizing the rapid and accurate positioning of the metering shell at the gluing station.

[0037] 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.

[0038] In this embodiment, 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 drive the glue gun 2210 to lift, translate, and move left and right, that is, to complete the movement of the preset trajectory through control, and at the same time the glue gun 2210 sprays glue to complete the gluing operation.

[0039] 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.

[0040] 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.

[0041] Combination Figures 7 to 9 , a stop mechanism A250 is arranged on the workbench B 270 corresponding to the end of the material preparation station, and a stop mechanism B260 is arranged corresponding to the end position of the waiting station. As shown in the figure, the stop mechanism A250 includes a gantry A251 supported on the workbench B270, and the gantry A251 is arranged across the top of the material guide frame 280, and has a stop cylinder A252 arranged one-to-one corresponding to the material guide groove 281, and the piston rod of the stop cylinder A252 faces downward and is connected to a stopper A253.

[0042] 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.

[0043] 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.

[0044] refer to Figures 1 to 13 The gas meter metering shell batch gluing device shown can be directly connected with the metering shell punch 100 through the transfer module 300. As shown in the figure, the metering shell coming out of the discharge port 110 of the metering shell punch 100 can be pushed into the corresponding gluing conveyor line 210 with the concave surface facing up after passing through the transfer module 30, and then sent to the waiting station by the gluing conveyor line 210, and pushed to the gluing station through the station switching mechanism 230. After completing the gluing operation, it is moved to the material taking station to wait for taking away.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
