Description

Technical Field

[0001] The utility model belongs to the technical field of gas meter production, in particular to a production device for gluing and assembling a membrane gas meter shell. Background Art

[0002] The statements in this section only provide background information related to the present disclosure, and these statements may constitute prior art. In the process of implementing the present utility model, the inventor found that there are at least the following problems in the prior art.

[0003] As a gas flow meter, gas meter is widely used in life and production. There are different types of gas meters according to different working principles. Among them, the diaphragm gas meter uses the effect of pressure difference to make the gas enter the metering chamber alternately through distribution, and then discharge to the outlet after filling, while pushing the diaphragm in the metering chamber to make reciprocating motion, and convert this cycle process into the corresponding gas flow through the conversion mechanism, thereby completing the metering function.

[0004] In the related technology, the base meter of the diaphragm gas meter mainly includes the upper shell group, the lower shell group, the movement and other components. The base meter of the gas meter is to seal the movement inside the upper and lower shell groups and work independently. As a safety workpiece, the base meter is not allowed to leak to the outside world, so the shell gluing production is particularly important. In the production process, the traditional gluing and assembly method relies on manual control of the batch of gas meter products and the rhythm of the production process, but the production efficiency is low and the yield rate of the products in the production process is low.

[0005] At present, some diaphragm gas meters use automated assembly processes for the gluing and assembly of gas meters (only the assembly of the shell, excluding the assembly of the movement). For example, the patent with application number 202311324080.1 and the name of the patent "Assembly process of diaphragm gas meter" uses an assembly line plus a robotic arm to apply glue and assemble the shell. Although the entire process assembly line is configured in a ring shape, it still occupies a large area. And it mainly uses four-axis and six-axis robotic arms for operations such as gluing and shell grabbing, which requires additional assembly positions for the robotic arms, making the entire process occupy a larger area. In addition, the maintenance of the robotic arm is also more troublesome.

DETAILED DESCRIPTION

[0045] The present invention is further described below in conjunction with the accompanying drawings. The embodiments of the present invention are only used to illustrate the present invention rather than to limit the present invention. Without departing from the technical concept of the present invention, various substitutions and changes can be made based on common technical knowledge and customary means in the field, which should all be included in the scope of the present invention.

[0046] like Figure 1 As shown, a production device for gluing and assembling a membrane gas meter shell includes:

[0047] The glue coating device 2000 comprises a main unit 2001, an adjustment component 2002, a glue gun component 2003 and a forward and backward movable tray 2005; the main unit 2001 is connected to a first end of the adjustment component 2002 through an upper bracket 2006 and a slide rail 2007, and the slide rail 2007 is slidably arranged on the upper bracket 2006; the glue gun component 2003 comprises a glue gun, which is connected to a second end of the adjustment component 2002; the forward and backward movable tray 2005 is arranged above the main unit 2001; the adjustment component is used to adjust the horizontal and vertical distances of the glue gun;

[0048] The frame assembly 1000 includes a frame 1001, and an upper desktop 1002 and a lower desktop 1003 connected to the frame 1001; the upper desktop 1002 is provided with a through slot; the host assembly 2001 is arranged in the gap between the upper desktop 1002 and the lower desktop 1003;

[0049] The housing positioning group 4000 includes a mold base 4005 for placing the upper housing group of the membrane type gas base meter 7000; the mold base 4005 is provided with a limiting cavity for positioning the upper housing group; the lower end of the mold base 4005 is connected to the forward and backward movable tray 2005 through the through slot of the upper table top 1002;

[0050] The material taking mechanism 3000 comprises two symmetrically arranged clamping cylinders 3102, a sliding cylinder 3105 and a grabbing assembly 3200; the fixed ends of the two clamping cylinders 3102 are connected to the upper table 1002, and the telescopic ends thereof are respectively connected to the two ends of the horizontal sliding rod of the sliding cylinder 3105; the lower end of the sliding cylinder 3105 is connected to the grabbing assembly 3200; the grabbing assembly 3200 is used to assemble the lower shell group of the membrane gas base meter 7000 with the glue-coated upper shell group;

[0051] The housing placement platform 5000 includes a positioning plate 5002 with a limiting cavity; the positioning plate 5002 is located directly below the sliding cylinder 3105;

[0052] The control system 6000 is used to control the operation of the glue coating device 2000 and the material taking mechanism 3000.

[0053] The present application firstly uses the forward and backward moving tray 2005 and the adjustment component 2002 to adjust the position of the upper shell group and the glue gun of the membrane gas base meter respectively, so that the glue gun can accurately apply glue to the upper shell group; then the lower shell group is grasped by the grasping component 3200, and it is accurately assembled with the upper shell group by the sliding cylinder 3105 and the pressing cylinder 3102, so as to complete the assembly of the gas base meter. With the above structure, the upper shell group, the lower shell group, and the movement of the membrane gas base meter 7000 can be automatically assembled into one by the dispersed components. The present application does not use a mechanical arm, and the glue coating equipment 2000, the material taking mechanism 3000 and other devices are cleverly arranged in the two-layer frame group 1000. The entire process equipment only needs the space occupied by the frame group, which not only reduces the floor space, but also makes maintenance very convenient.

[0054] In the frame assembly 1000, the frame 1001 is provided with a plurality of columns, such as Figure 1 2. The upper desktop 1002 is connected to the frame 1001 up and down. The upper desktop 1002 is provided with a positioning hole, and the frame 1001 is correspondingly provided with a positioning hole. The positioning hole of the upper desktop 1002 and the positioning hole of the frame 1001 are connected and positioned by a positioning pin.

[0055] The upper table 1002 is connected to the material taking mechanism, specifically, the upper table 1002 is connected to the pressing cylinder 3102 of the material taking mechanism. The fixed end of the pressing cylinder 3102 can also be connected to the upper table 1002 through a fixing block 3101. The fixing block 3101 and the pressing cylinder 3102 are provided with positioning holes, which are fastened by screws.

[0056] The lower desktop 1003 is connected to the frame 1001 inside and outside. The lower desktop 1003 and the frame 1001 have shape limits, and positioning pins are set on the lower desktop 1003 and the frame 1001. The lower desktop 1003 has a shape groove, which is connected and positioned with the column of the frame 1001.

[0057] The main unit 2001 includes a driving device and an upper bracket 2006, which is arranged at the bottom of the glue coating device 2000 and connected to the lower table 1003. Figure 3 As shown, the main unit 2001 is connected to the lower desktop 1003 through the horizontal adjustment pad 2004, so that the angle of the gluing equipment on it can be adjusted through the horizontal adjustment pad 2004 to avoid the uneven ground. And the horizontal adjustment pad 2004 can also play a good shock-absorbing role, avoiding the accuracy of the shell gluing and assembly being affected by the movement and compression of the components on it. The horizontal adjustment pad 2004 is provided with a positioning hole, and the positioning hole of the main unit 2001 and the positioning hole of the horizontal adjustment pad 2004 are positioned and connected by a positioning pin. The driving device of the main unit 2001 is connected to the forward and backward moving tray 2005 to drive it to move forward and backward.

[0058] The control system 6000 is a conventional device, including a control panel, a key combination, etc. The control system 6000 is connected to the main unit 2001, the slide rail 2007, the adjustment component 2002, the glue gun component 2003, the clamping cylinder 3102, the sliding cylinder 3105, the grabbing component 3200, the rotating cylinder 4002, etc. to control the operation of the above components. In order to achieve automation, the control system also includes a communication module and multiple sensors; the multiple sensors are used to monitor the state of the membrane gas base meter 7000 in the gluing and assembly process, and send them to the control system 6000, so that the control system 6000 can control the shell gluing and installation process, and perform abnormal alarms, etc. For example, a workpiece sensor can be set at the shell positioning group 4000, and when it is detected that the upper shell group is located in the limit cavity of the shell positioning group 4000, the gluing device is started. Alternatively, a displacement sensor is set, and when it is detected that the glue gun is located at a predetermined position above the shell positioning group 4000, the gluing operation is performed on the upper shell group, and so on. Thus, the gluing and assembly of the shell are automated. The control system 6000 is a prior art and does not fall within the protection scope of this patent.

[0059] The upper desktop may be provided with a gap for the upper bracket 2006 of the host assembly 2001 to pass through, such as Figure 1Or as shown in 2, so that the main unit 2001 can well support the upper slide rail 2007, adjustment assembly 2002 and glue gun assembly 2003, etc., and is conducive to the effective stacking of various devices.

[0060] The upper and lower desktops can be shielded by a cover plate 1004 and a decorative cover 1005, leaving only a space for the control panel of the control system 6000. Figure 1 As shown, the control system 6000 and the host assembly 2001 are not affected by dust or debris, and are more beautiful. The frame 1001 is connected to the cover plate 1004 and the decorative cover 1005 up and down.

[0061] The adjustment assembly 2002 and the glue gun assembly 2003 are assembled with each other, and their function is to adjust the position of the glue gun when applying glue, so as to cooperate with the forward and backward moving tray 2005 that adjusts the position of the upper shell assembly. Figure 3 As shown, the adjustment assembly 2002 includes a horizontal adjustment block and a vertical adjustment block; one end of the vertical adjustment block is connected to the slide rail 2007, and the other end is connected to the side end of the glue gun through the horizontal adjustment block. The vertical adjustment block and the horizontal adjustment block are used to adjust the vertical and horizontal positions of the glue gun respectively, and cooperate with the forward and backward moving tray 2005 so that the glue gun can accurately apply glue according to the edge track of the upper shell assembly. Other existing technologies can also be used to achieve the adjustment of the glue gun position.

[0062] The slide rail 2007 is provided with a positioning hole, which is positioned and connected with the positioning hole of the vertical adjustment block through a positioning pin. The horizontal adjustment block is provided with a shape groove, which is connected with the shape boss of the vertical adjustment block.

[0063] In order to apply glue more accurately, Figure 6 As shown, the shell positioning group further includes a rotating cylinder 4002 and a base 4001 disposed below the jig base 4005; the jig base 4005 is connected to the forward and backward moving tray 2005 through the rotating cylinder 4002 and the base 4001. Since the rotating cylinder 4002 can rotate in the base 4001, the jig base 4005 thereon can be driven to rotate accordingly, so that the angle of the upper shell group can be adjusted in coordination with the forward and backward moving tray 2005 during gluing, so that the gluing accuracy is higher.

[0064] like Figure 6 As shown, the lower end of the jig seat 4005 can also be connected to the upper end of the rotary cylinder 4002 through the turntable 4003, so that the rotary cylinder 4002 drives the upper jig seat 4005 to rotate through the turntable 4003, so that the angle of the shell can be adjusted during glue coating.

[0065] The base 4001 is provided with a first positioning hole, which is connected and fastened with the first positioning hole of the rotary cylinder 4002 by screws. The second positioning hole of the rotary cylinder 4002 is connected and fastened with the first positioning hole of the rotary disk 4003 by screws. The rotary disk 4003 is provided with a second positioning hole, which is connected and fastened with the first positioning hole of the jig base 4005 by screws.

[0066] like Figure 6 As shown, the limiting cavity of the jig seat 4005 is used to position the upper shell assembly at a predetermined position before gluing. The jig seat (4005) is provided with a through slot for placing the inlet and outlet ends of the upper shell assembly; a spring screw (4006) is provided in the through slot of the jig seat (4005) to support the inlet and outlet ends to ensure that the position of the upper shell assembly does not shift, and there is no need to worry about the displacement of the upper shell assembly when the tray 2005 is moved forward and backward or the cylinder 4002 is rotated to adjust the position of the upper shell assembly, which affects the accurate gluing. The spring screw 4006 is installed in the threaded hole provided in the jig seat 4005.

[0067] Similarly, the positioning plate 5002 of the housing placement table 5000 is also provided with a limiting cavity so that the lower housing assembly is located at a predetermined position before being grabbed by the grabbing assembly 3200, thereby ensuring that the lower housing assembly and the upper housing assembly can be accurately assembled. Since the grabbing assembly 3200 needs to grab the lower housing assembly to a height exceeding the upper housing assembly and the movement, the positioning plate 5002 is connected to the upper table 1002 through the equal height column 5001, such as Figure 1 Or as shown in 7, to reduce the up and down moving distance of the clamping cylinder 3102, to avoid vibration caused by long-distance movement and displacement of the grasped lower shell group.

[0068] The first positioning hole of the height-equalizing column 5001 and the positioning hole of the positioning plate 5002 are connected and fastened by screws. The height-equalizing column is provided with a second positioning hole, which is fixedly connected to the upper desktop 1002.

[0069] At the same time, damper assemblies 3104 are provided at both ends of the horizontal sliding rod of the sliding cylinder 3105. Figure 4 As shown, the impact force of the sliding cylinder 3105 when it moves can be reduced, thereby preventing the lower housing assembly being grasped from shifting due to vibration. At the same time, the noise in the tooling state can be reduced, and the designated position can be reached accurately. The damper assembly 3104 is a conventional component, which itself does not belong to the protection scope of this patent.

[0070] The damper assembly may use a damper of model ACA0810-2. Fig.15 As shown, the body 3104-1 is assembled with the nut group 3104-2 and the hydraulic rod 3104-3 respectively, the hydraulic rod 3104-3 is connected with the protective cover 3104-4, and the body 3104-1 is assembled with the end of the horizontal sliding rod of the sliding cylinder 3105.

[0071] The pressing cylinder 3102 is connected to one end of the horizontal slide rail of the sliding cylinder 3105 through the connecting block 3103. Figure 4 As shown. The connecting block 3103 is provided with positioning holes at the ends of the horizontal slide rods of the pressing cylinder 3102 and the sliding cylinder 3105, respectively, and is fixed by screws. The end of the horizontal slide rod of the sliding cylinder 3105 is provided with a positioning hole, and the damper assembly 3104 is connected to the end of the horizontal slide rod through the positioning hole.

[0072] The grabbing assembly 3200 and the sliding cylinder 3105 are provided with positioning holes and fastened by screws. The grabbing assembly 3200 can be used in a variety of ways to grab the lower shell assembly of the gas base meter. Figure 5 As shown, the grasping assembly 3200 includes a pressure plate 3202, a cavity 3201, an air inlet nozzle 3203, a suction cup 3204 and a vacuum valve; the cavity 3201 is connected to the sliding cylinder 3105 through the pressure plate 3202; the control system 6000 is provided with a vacuum valve, the pressure plate 3202 and the cavity 3201 are provided with a through hole connected to the air inlet nozzle 3203 and interconnected, and the vacuum valve is connected to the suction cup 3204 through a pipeline, the air inlet nozzle 3203 and the through hole.

[0073] The vacuum valve can be arranged in the control box of the control system 6000, the suction cup 3204 is fixed in the through hole of the cavity 3201, the pressing plate 3202 is connected to the through hole of the cavity 3201, and the air inlet nozzle 3203 is arranged at the upper end of the through hole of the pressing plate 3202, so that the vacuum valve can be connected to the suction cup 3204 in the through hole of the cavity 3201 through the pipeline and the air inlet nozzle 3203. When it is necessary to grab the lower shell group, first control the clamping cylinder 3102 to move downward so that the lower shell group is sucked into the cavity 3201 by the suction cup 3204; then, the lower shell group is moved to the top of the upper shell group that has been glued by the clamping cylinder 3102 and the sliding cylinder 3105, and the clamping cylinder 3102 is controlled to move the lower shell group downward to complete the assembly with the upper shell group; the vacuum valve is exhausted so that the suction cup 3204 no longer adsorbs the lower shell group, ensuring that the lower shell assembly is smoothly removed from the cavity; after the assembly is completed, the clamping cylinder 3102 rises and the sliding cylinder 3105 returns to its initial state.

[0074] In order to keep the lower shell group horizontally and uniformly pressed down during the assembly process, the control system 6000 is also provided with an air intake valve, and the pressing plate 3202 and the cavity 3201 are provided with mutually communicating vents, and the air intake valve is connected to the vents through a pipeline, and is used to inflate the cavity 3201. When the vacuum valve exhausts air so that the suction cup 3204 no longer adsorbs the lower shell group, the air intake valve opens at the same time, thereby inflating the cavity 3201, so that the lower shell group is kept horizontally and uniformly pressed down during the assembly process, ensuring that the lower shell group can be smoothly removed from the cavity 3201. At this time, after being pressed down, the lower shell group maintains a certain gap with the rubber surface of the upper shell group, thereby also ensuring that the rubber surface is uniform and does not overflow.

[0075] An air inlet nozzle 3203 may also be provided above the vent hole of the pressing plate 3202, so that the pipeline of the air inlet valve is connected to the vent hole through the air inlet nozzle 3203. The air inlet nozzle 3203 may also be provided in the through hole and the vent hole.

[0076] The structure of the grabbing assembly 3200 is simple, and it is easier to maintain than a mechanical arm. Of course, other existing grabbing assemblies 3200 may also be used.

[0077] The pressing plate 3202 and the cavity 3201 are provided with a first positioning hole, and screws are used to fasten them.

[0078] The process flow of this application is as follows:

[0079] In the first step, the upper shell assembly is placed in the limiting cavity of the mold base 4005 of the shell positioning assembly 4000, and the workpiece sensor intervenes and sends a signal to the control system 6000; the control system 6000 starts the glue coating device 2000, such as Figure 8 As shown;

[0080] In the second step, the glue coating device 2000 controls the glue gun to move to the glue coating position, and at the same time, the main unit 2001 controls the front and rear moving tray 2005 to transport the upper shell assembly located at the upper end of the shell positioning unit 4000 to the bottom of the glue gun; the glue gun moves downward, and starts to coat the glue with the cooperation of the front and rear moving tray 2005, the adjustment assembly 2002 and the rotating cylinder 4002, as shown in FIG. Fig. 9 As shown; after gluing is completed, it returns to the initial position, where there is a displacement sensor;

[0081] The third step is to place the lower housing assembly into the limiting cavity of the positioning plate 5002 of the housing placement table 5000 and enter a waiting state. Fig.10 As shown;

[0082] Step 4: After the third step is completed, the grabbing assembly 3200 moves downward to allow the lower shell assembly to enter the material-taking cavity 3201. At the same time, the vacuum valve sucks air and the suction cup 3204 works to complete the grabbing of the lower shell assembly. Fig.11After the grab assembly 3200 moves upward, it moves to the top of the housing positioning group 4000 on the right, as shown Fig.12 As shown, then go down to assemble the lower shell assembly with the upper shell assembly, as shown Fig.13 As shown;

[0083] The fourth step is to identify the product. If there is no abnormality, the vacuum valve of the grabbing assembly 3200 is controlled to exhaust, and the air inlet valve is opened to inflate, so that the suction cup 3204 no longer adsorbs the lower shell assembly, and the grabbing assembly 3200 is moved to the initial position. Thus, the upper and lower shells are assembled. Fig.14 As shown;

[0084] Step 5: Take out the assembly tool and transfer it to the assembly line for curing. The equipment enters the standby state. Figure 1 shown.

[0085] The present application adopts a two-layer design of upper and lower tables to reasonably stack the gluing and assembly equipment, and does not require a robotic arm. Instead, a forward and backward moving tray 2005, an adjustment component 2002 and a rotating cylinder 4002 are used to perform the gluing process, and a sliding cylinder 3105 and a grabbing component 3200 are used to perform the assembly process. It has a simple structure, occupies a small area, and is very convenient to maintain.

[0086] The fixed connection not specifically mentioned above may be a connection method such as riveting, welding, bolt connection, etc., and the movable connection may be a connection method such as hinged connection.
