Description

Technical Field

[0001] This utility model belongs to the field of gas meter component manufacturing, specifically relating to a station switching mechanism for a meter housing adhesive coating device. Background Technology

[0002] The meter housing is a crucial component of a diaphragm gas meter, typically manufactured using a stamping process. Both the gas meter movement and the meter housing have sealing surfaces. After the main body is formed, a sealing strip is installed on the inner side of the meter housing to further improve the sealing of the diaphragm cavity. Traditionally, this involves directly bonding a finished sealing ring or transferring the meter housing to an adhesive coating device for on-site adhesive application to form a ring-shaped sealing strip. However, traditional adhesive coating equipment is unsuitable for batch application of meter housings, severely impacting production efficiency. Furthermore, it is difficult to integrate with stamping dies, hindering automated integrated production of the meter housing and limiting production quality and efficiency. This application proposes a station switching mechanism to improve the efficiency of the adhesive coating device, significantly enhancing the flow efficiency and positional accuracy of the meter housing. Utility Model Content

[0003] In view of this, the present invention provides a station switching mechanism for a metering shell gluing device to solve the problems of poor metering shell turnover efficiency and inaccurate positioning in the prior art.

[0004] The technical solution is as follows:

[0005] A station switching mechanism for a metering shell gluing device, wherein the metering shell gluing device includes a guide frame, the guide frame having a guide trough arranged along its length, one end of the guide trough being a feeding end and the other end being a discharging end, the guide frame being sequentially divided into a material preparation station, a waiting station, a gluing station, and a material picking station along its length, wherein the material picking station is close to the discharging end; the key feature is:

[0006] The station switching mechanism is used to move the metering shell in the waiting station and the glue application station forward by one station. It includes a mounting plate located below the guide frame and spanning all guide grooves, and a station switching drive assembly for driving the mounting plate to slide horizontally and rise vertically along the length of the guide groove.

[0007] The mounting plate has a pusher assembly that corresponds to the guide groove. The pusher assembly includes pusher A, pusher B and pusher C arranged sequentially in the direction away from the feed end, wherein the horizontal distance between pusher A and pusher B is adapted to the length of the metering shell.

[0008] By adopting the above scheme, setting up multiple workstations and using them in conjunction with the workstation switching mechanism, it is beneficial to ensure the orderly progress of the glue application operation and avoid interference between the front and back. On the other hand, the workstation switching mechanism with fixed action adopted in this application for the waiting workstation and the glue application workstation can better ensure the consistency of the position and posture of the metering shell and improve the glue application quality compared with the traditional synchronous belt conveyor positioning.

[0009] Preferably, the workstation switching mechanism further includes a base plate, with a mounting plate located directly above it. The base plate has symmetrically arranged vertical support plates at both ends, each with a slide block that slides vertically against it, and a lifting cylinder for driving the slide block to move vertically. The left and right ends of the mounting plate slide against the slide block via a horizontal guide structure, with the guide direction parallel to the guide chute, and are equipped with horizontal switching cylinders to drive the mounting plate to slide along the guide chute. This design facilitates modular assembly and disassembly, improves assembly and disassembly efficiency, and results in a compact overall structure.

[0010] Preferably, a lifting cylinder is provided above the mounting plate, and the lifting cylinder is supported on the base plate by a support rod. The mounting plate has strip-shaped clearance holes corresponding to the support rod. With this design, the lifting cylinder is used to lift and position the metering shell, further improving the consistency of the adhesive application position and posture. Simultaneously, being supported on the base plate facilitates modular design and saves space.

[0011] Preferably, the piston rod of the lifting cylinder faces upward and has a horizontally arranged top plate, the width of which is less than or equal to the width of the guide trough. This design helps ensure the stability of the metering shell when it is lifted and prevents tilting.

[0012] Preferably, the pusher component B is a grouped rod-shaped structure or a frame structure. This design is simple in structure, easy to implement, and has extremely low implementation costs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The station switching mechanism for the metering shell gluing device provided by this utility model is mainly designed for the waiting station and the gluing station. It fully ensures the consistency of the gluing position and posture, improves the gluing efficiency and quality, and the modular design is conducive to improving the ease of disassembly and assembly and the overall structural compactness.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] refer to Figures 1 to 4 The station switching mechanism shown is for a metering shell gluing device, wherein the metering shell gluing device includes a guide frame 280, the guide frame 280 has a guide groove 281 arranged along its length direction, one end of the guide groove 281 is the feeding end, the other end is the discharging end, the guide frame 280 is divided into a material preparation station, a waiting station, a gluing station and a material picking station along its length direction, wherein the material picking station is close to the discharging end.

[0021] The station switching mechanism in this application is mainly used to move the metering shell in the waiting station and the gluing station forward by one station. It includes a mounting plate 231 located below the guide frame 280 and spanning all guide grooves 281, and a station switching drive assembly for driving the mounting plate 231 to slide horizontally and rise vertically along the length direction of the guide groove 281. As shown in the figure, the mounting plate 231 is arranged along the width direction of the guide frame 280.

[0022] The mounting plate 231 has pusher components that correspond one-to-one with the guide grooves 281. The pusher components include those that extend away from the feed end ( Figure 4 Pusher components A2310, B2311, and C2312 are arranged sequentially in the direction of the middle right end. The horizontal distance between pusher components A2310 and B2311 is adapted to the length of the metering shell. In specific implementation, pusher component B2311 is a group of rod-shaped structures or frame structures.

[0023] The workstation switching mechanism also includes a base plate 232, a mounting plate 231 located directly above the base plate 232, and vertical support plates 233 symmetrically arranged at both ends of the base plate 232. The vertical support plates 233 have slide blocks 234 that slide vertically with them, and lifting cylinders 235 for driving the slide blocks 234 to move vertically. The left and right ends of the mounting plate 231 slide with the slide blocks 234 through horizontal guide structures, and the guide direction is parallel to the guide groove 281. A horizontal switching cylinder 236 is configured to drive the mounting plate 231 to slide along the direction of the guide groove 281. The lifting cylinder 235, the horizontal switching cylinder 236, and the corresponding guide structures constitute the workstation switching drive assembly.

[0024] A lifting cylinder 241 is provided above the mounting plate 231. The lifting cylinder 241 is supported on the base plate 232 by a support rod 244. The mounting plate 231 has a strip-shaped clearance hole 2313 corresponding to the support rod 244.

[0025] The piston rod of the lifting cylinder 241 faces upward and has a horizontally arranged top plate 242, the width of which is less than or equal to the width of the guide chute 281.

[0026] refer to Figures 1 to 4 The station switching mechanism shown for the metering shell gluing device includes, in a specific implementation, a workbench B270 and a gluing conveyor line 210 corresponding to the guide chute 281. The conveying length covers the length of the material preparation station and the waiting station. In addition, a gluing mechanism 220 is provided for the corresponding gluing station. The gluing mechanism 220 is used to perform gluing operation on the metering shells in the gluing station. The station switching mechanism 230 mainly moves the metering shells in the waiting station to the gluing station and moves the metering shells in the gluing station to the material picking station.

[0027] In addition, the guide frame 280 has at least two diagonally distributed positioning pins 243 at the position corresponding to the glue application station. The positioning pins 243 are distributed in a position that corresponds to the position of the through hole on the outer edge of the metering shell. When the metering shell is in the glue application station, the top plate 242 lifts the metering shell, and at the same time, the positioning pins 243 are inserted into the corresponding through hole of the metering shell to support and position the metering shell, ensuring the stability of the glue application process and improving the glue application quality.

[0028] During operation, the metering shell is pushed onto the corresponding glue-applying conveyor line 210 with its concave surface facing upwards, and then sent to the waiting station by the glue-applying conveyor line 210. The two actions of the metering shell moving from the waiting station to the glue-applying station and the metering shell moving from the glue-applying station to the material-picking station are completed simultaneously by the station switching mechanism 230, which quickly realizes station flow and improves production efficiency. At the same time, because the pusher component B2311 adopts a grouped rod-shaped structure or frame structure, it is not blocked by the lifting cylinder 241 during the forward and backward sliding process, which can well realize the glue-applying operation after the metering shell is accurately positioned. The whole has excellent compactness and convenient disassembly and assembly.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
