Description

Technical Field

[0001] This invention belongs to the field of gas meter component manufacturing, specifically relating to a rapid production method for diaphragm gas meter housings. Background Technology

[0002] The meter housing is a crucial component of diaphragm gas meters, 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 performance of the diaphragm cavity. Traditionally, this involves directly bonding a finished sealing ring or transferring the meter housing to an adhesive applicator for on-site application to form a ring-shaped sealing strip. Both processes increase the need for transporting and independently supplying the meter housing, significantly reducing production efficiency and increasing space requirements, hindering rapid mass production. Furthermore, traditional adhesive application methods also affect the sealing quality of the adhesive ring, especially at the initial and final application points, where cracks are easily formed, severely impacting the quality of the finished meter housing. Summary of the Invention

[0003] In view of this, the present invention provides a rapid production method for diaphragm gas meter housings to solve the problems of low production efficiency and low yield rate of gas meter housings in the prior art.

[0004] The technical solution is as follows:

[0005] A rapid production method for diaphragm gas meter housings, the key of which includes the following steps:

[0006] S1, Metering shell is stamped using a metering shell punch press;

[0007] S2, After the stamped metering shell is flipped over with the concave side facing up, it is placed on the batch gluing device for batch gluing operation.

[0008] S3: The metering shells with the adhesive coating are picked up in batches and placed on a special tray.

[0009] By adopting the above solution, the cycle from blank stamping to glue application can be shortened, which is beneficial to improving the production efficiency of metering shells.

[0010] Preferably, in step S2, a transfer module is used to flip the metering shell and send it into the batch gluing device. Using a transfer module for automatic flipping of the metering shell allows it to quickly enter the gluing device from the punch press, eliminating the need for manual transfer and flipping, which is beneficial for mass production and further improves the production efficiency of the metering shell.

[0011] Preferably, the sealing ring of the metering shell is a rectangular closed loop, including a short side and a long side, where the length of the short side is 'a'. During the adhesive application process, the adhesive is applied starting from a position near the middle of the short side, with the adhesive amount increasing linearly until a stable adhesive amount Q is reached within the stroke L. When the adhesive application reaches the initial spraying position, the adhesive amount decreases linearly in the same way, reducing to zero within the stroke L, where L ≤ a / 2. Using this scheme, the appropriate adhesive amount is ensured while increasing the connection length through linear increases and decreases within the stroke L, which helps improve the connection quality and prevent cracks, thus improving the quality of the sealing ring.

[0012] Preferably, the sealing ring of the metering shell is a rectangular closed loop, including a short side and a long side, with a rounded chamfer section between the short and long sides. During the adhesive application process, adhesive is applied from the middle of the rounded chamfer section with a stable amount of adhesive Q, and application stops when the closed loop returns to the initial spraying position. Using this method, the centripetal force of the rounded chamfer section effectively enhances the contact strength at the contact point, which also helps to improve the quality of the sealing ring.

[0013] Preferably, the metering shell punch has an outlet for the metering shells formed by stamping to be removed, and the batch coating device includes multiple coating conveyor lines and a coating mechanism corresponding to the coating conveyor lines.

[0014] The transfer module is located between the metering shell punching machine and the batch gluing device. It includes transfer conveyor line A, transfer conveyor line B, and a feeding mechanism. A flipping mechanism is provided between transfer conveyor line A and transfer conveyor line B. Transfer conveyor line A receives the metering shells sent from the outlet. After being flipped by the flipping mechanism, the metering shells enter transfer conveyor line B with their concave surface facing upwards. The feeding mechanism automatically delivers the metering shells on transfer conveyor line B to the gluing conveyor line. Using this solution, the transfer module connects the metering shell punching machine and the batch gluing device, directly transferring the stamped metering shells to the gluing device in an orientation conducive to gluing. This achieves rapid stamping and gluing, significantly improving the production efficiency of the finished metering shells, facilitating the rapid assembly of subsequent gas meters, and reducing labor intensity and space occupation.

[0015] As a preferred option, step S3 employs a pallet loading and unloading module for automated pallet supply, transfer, and gripping of the metering shells. This approach enables automated transfer of the metering shells, saving manpower and improving production efficiency.

[0016] Preferably, the pallet loading and unloading module includes a pallet supply unit and a pallet transfer unit. The pallet supply unit includes an empty pallet stacking station, a pallet transfer line and an empty pallet gripper assembly corresponding to the empty pallet stacking station. The pallet transfer line has a pallet placement position and a pallet waiting position. The empty pallet gripper assembly can grab the empty pallet at the empty pallet stacking station and place it in the pallet placement position, and then transport it to the pallet waiting position.

[0017] The pallet transfer unit includes a pallet fixing station and a full-load pallet stacking station, as well as a pallet fixing component and a metering shell gripper assembly corresponding to the pallet fixing station, and a full-load pallet gripper assembly for picking up pallets at the pallet fixing station and placing them on the full-load pallet stacking station. The metering shell gripper assembly is used to pick up metering shells that have been coated with adhesive and place them on the pallets at the pallet fixing station. Using this solution, it is used in conjunction with an adhesive coating device, installed at the discharge end of the adhesive coating device. First, empty pallets are stacked at the empty pallet stacking station. Then, the empty pallet gripper assembly and the pallet transfer line are used to intermittently transport pallets to the pallet fixing station. The metering shell gripper assembly picks up metering shells that have been coated with adhesive from the adhesive coating device and places them on the pallets at the pallet fixing station. When the corresponding pallet is full, it can be picked up and stacked on the full-load pallet stacking station by the full-load pallet gripper assembly, facilitating centralized handling, reducing the impact on the quality of the adhesive rings during the process, improving the loading and unloading efficiency of the metering shells, and benefiting the mass production of the metering shells.

[0018] Preferably, the pallet loading and unloading module includes a rectangular main frame beam structure, and the pallet transfer line is set along the width direction of the main frame beam structure. The empty pallet stacking station and the fully loaded pallet stacking station are located on one side of the pallet transfer line and correspond to the pallet placement position and the pallet fixing position, respectively. The pallet fixing position is located directly above the pallet waiting position.

[0019] As a preferred option, in step S2, after the adhesive is applied, the metering shell is dried. This method accelerates the solidification of the adhesive ring, reduces or avoids deformation caused by shaking during transport, and ensures that the sealing ring has good molding quality.

[0020] As a preferred option, in step S2, the metering shell is positioned and fixed during the adhesive application process. This approach ensures the consistent position of the metering shell, allowing for precise alignment with the adhesive application device, while also reducing the impact of device vibration on the adhesive application quality.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The rapid production method for diaphragm gas meter housings provided by this invention can greatly improve the production efficiency of diaphragm gas meter housings, while ensuring the quality of adhesive coating and reducing the impact of the processing or transportation process, thereby improving the quality of the housings and ensuring a high yield rate.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings.

[0053] refer to Figures 1 to 29 The rapid production method for diaphragm gas meter housing shown mainly includes the following steps: First, the meter housing is stamped and formed using a meter housing punch press 100; second, the stamped meter housing is flipped over and placed with the concave side facing up on a batch gluing device 200 for batch gluing; third, the glued meter housings are batch-grabbed and placed on a special tray.

[0054] To improve overall production efficiency, in the second step of this application, a transfer module 300 is used to flip the metering shell and send it into the batch gluing device 200, which can realize an integrated production mode and save space.

[0055] As shown in the figure, the rapid production method of the diaphragm gas meter housing of this application is mainly completed by a dedicated rapid production line. The dedicated rapid production line includes the aforementioned meter housing punch 100, batch gluing device 200 and transfer module 300. The meter housing punch 100 is mainly used for stamping and forming the meter housing and has a discharge port 110 for removing the stamped meter housing.

[0056] The batch coating device 200 includes multiple coating conveyor lines 210 and coating mechanism 220 corresponding to the coating conveyor lines 210.

[0057] The transfer module 300 is located between the metering shell punching machine 100 and the batch gluing device 200. It 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. The transfer conveyor line A310 is used to receive the metering shells sent from the discharge port 110. After being flipped by the flipping mechanism 340, the metering shells enter the transfer conveyor line B320 with their concave surfaces facing upwards. The feeding mechanism 330 sends the metering shells located on the transfer conveyor line B320 to the gluing conveyor line 210.

[0058] Key reference Figures 1 to 5 The transfer module 300 mainly includes a workbench A350, and transfer conveyor lines A310 and B320 are both horizontally mounted on the workbench A350 via a frame A351. In this embodiment, both are belt conveyors, and transfer conveyor line B320 is located directly below transfer conveyor line A310. One end of transfer conveyor line A310 has a ramp section 311, and a flipping mechanism 340 is provided corresponding to the ramp section 311.

[0059] As shown in the figure, the flipping mechanism 340 includes a stop plate 341 and at least one retaining block 342. The stop plate 341 corresponds to the lower end of the ramp section 311, and the vertical distance between it and the end of the ramp section 311 is less than half the width of the metering shell and greater than the thickness of the metering shell. The at least one retaining block 342 corresponds to the upper end of the ramp section 311 and is rotatably disposed directly above the upper end of the ramp section 311. The vertical distance between the retaining block 342 and the upper end of the ramp section 311 is less than the thickness of the metering shell.

[0060] 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 located above the transfer conveyor line A310. The holding block 342 is suspended on the support frame 352 by a hook 353. The hook 353 can rotate relative to the support frame 352, and the holding 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, there are two holding blocks 342, one of which is set at the upper end of the ramp section 311, and the other is set at the middle of the ramp section 311.

[0061] The stop plate 341 is located directly in front of the lower end of the ramp section 311. The transfer conveyor line B320 is slightly longer at one end of the ramp section 311, ensuring that the metering shell falling from the gap between the stop plate 341 and the ramp section 311 can land on the transfer conveyor line B320. The transfer conveyor line B320 and the transfer conveyor line A310 have opposite conveying directions. Thus, the metering shell (concave side down) conveyed from its horizontal section into the ramp section 311 on the transfer conveyor line A310 is restricted by the holding block 342 and can basically maintain its posture in contact with the conveying surface. Then, under the action of the stop plate 341, its lower side in the length direction contacts the transfer conveyor line B320 at a slightly inclined angle. Due to the inertia of the transfer conveyor line B320, its upper side falls backward. At this time, the concave side of the metering shell faces upward, thus realizing the flipping of the metering shell.

[0062] In this embodiment, the feeding mechanism 330 is located on one side of the width direction of the transfer conveyor line B320. It mainly includes a base plate 331, a mounting frame 332 supported on the base plate 331, a feeding frame 333 movably disposed on the mounting frame 332, and a feeding cylinder 334 connected to the feeding frame 333. The feeding frame 333 has a pusher plate 335 disposed perpendicular to the length direction of the transfer conveyor line B320. The feeding cylinder 334 is used to drive the feeding frame 333 to move closer to or away from the transfer conveyor line B320. During installation, the feeding mechanism 330 is fixed to the workbench A350 by the base plate 331.

[0063] In practice, the mounting bracket 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, with its piston rod facing upward and connected to the mounting bracket 332. In this way, the overall height of the mounting bracket 332 can be adjusted by the height adjustment cylinder 336.

[0064] The feeding rack 333 and the mounting frame have a horizontal guide structure, and the guide direction is perpendicular to the conveying direction of the transfer conveyor line B320. The pusher plates 335 on the feeding rack 333 are distributed at intervals. At the same time, the frame A351 is equipped with a feeding alignment plate 337 and multiple feeding sensor seats 338 corresponding to the transfer conveyor line B320. The feeding alignment plate 337 is mounted on the transfer conveyor line B320 and is relatively far away from the inclined section 311. The feeding sensor seats 338 are set one-to-one with the pusher plates 335. The feeding alignment plate 337 and the multiple feeding sensor seats 338 are equipped with material sensors to detect whether there are metering shells at the corresponding positions on the transfer conveyor line B320. When the metering shells are transferred to the transfer conveyor line B320 in sequence, when the first metering shell abuts against the feeding alignment plate 337, there will basically be one metering shell facing the pusher plate 335. In this way, the pusher plate 335 can push the facing metering shell to the other side of the transfer conveyor line B320.

[0065] Key reference Figures 1 to 17 The batch coating device 200 of this application mainly includes a workbench B270, and a guide rack 280, a coating conveyor line 210 and a coating mechanism 220 disposed on the workbench B270, as shown in the figure. The guide rack 280 has a guide groove 281 that corresponds one-to-one with the coating conveyor line 210. The guide groove 281 has symmetrically arranged steps on the two inner sides facing each other in the length direction, which can allow the metering shell to be suspended and supported in the guide groove 281.

[0066] The guide rack 280 is divided into a preparation station, a waiting station, an adhesive application station, and a material picking station along its length. The adhesive application conveyor line 210 is located below the guide rack 280 and covers the length of the preparation station and the waiting station. The adhesive application mechanism 220 is set corresponding to the adhesive application station. A station switching mechanism 230 is set below the guide rack 280. The station switching mechanism 230 is used to move the metering shells in the waiting station and the adhesive application station forward one station in sequence. That is, the metering shells in the guide trough 281 are moved from the entry end of the preparation station to the waiting station via the adhesive application conveyor line 210. The station switching mechanism 230 can move the metering shells in the waiting station 230 to the adhesive application station and move the metering shells in the adhesive application station to the material picking station.

[0067] The batch coating device 200 includes a positioning mechanism 240 corresponding to the coating station. This allows for the positioning and fixing of the metering shell during the coating process, improving the coating quality. As shown in the figure, each guide trough 281 has a corresponding positioning mechanism 240. The positioning mechanism includes a lifting cylinder 241 located below the 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 guide trough 281. The 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 hole on the outer edge of the metering shell. When the metering shell is in the coating station, the lifting cylinder 241 operates, lifting the metering shell through the top plate 242. At the same time, the positioning pins 243 are inserted into the corresponding through hole of the metering shell, providing support and positioning for the metering shell, ensuring the stability of the coating process, and improving the coating quality.

[0068] In this embodiment, the two actions of moving the metering shell of the waiting station 230 to the glue application station and moving the metering shell of the glue application station to the material picking station are completed simultaneously by the station switching mechanism 230. As shown in the figure, the mechanism 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 of the guide grooves 281. The station switching drive assembly mainly includes a base plate 232. During installation, the entire station switching mechanism 230 passes through the base plate. 232 is fixed on the workbench B270. The base plate 232 has symmetrically arranged vertical support plates 233 on both sides. 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. At the same time, the left and right sides 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.

[0069] The mounting plate 231 has a pusher assembly that corresponds one-to-one with the guide groove 281. The pusher assembly is mainly used to push the metering shell forward. In this embodiment, the pusher assembly includes pusher A2310, pusher B2311 and pusher C2312 arranged sequentially along the direction away from the glue coating conveyor line 210. The horizontal distance between pusher A2310 and pusher B2311 is adapted to the length of the metering shell, so as to better realize the rapid and accurate positioning of the metering shell at the glue coating station.

[0070] It should be noted that in this embodiment, in order to make full use of the height space and improve the compactness and ease of installation of the overall structure, the lifting cylinder 241 is directly supported on the base plate 232 by the support rod 244. The lifting cylinder 241 is located above the base plate 232. Correspondingly, the mounting plate 231 has a strip-shaped clearance hole 2313 corresponding to the support rod. The strip-shaped clearance hole 2313 is set along the length direction of the guide groove 281, so as not to hinder the back and forth sliding of the base plate 232. At the same time, the pusher B2311 adopts a grouped rod-shaped structure or frame structure. During the back and forth sliding process, it is not blocked by the lifting cylinder 241, but its width can be less than or equal to the width of the metering shell.

[0071] refer to Figures 6 to 11 The glue application mechanism 220 mainly includes a glue gun moving unit and a glue quantity control unit. The glue gun moving unit includes a glue gun fixing plate 221 and a three-axis gantry module 222 that controls the movement trajectory of the glue gun fixing plate 221. The three-axis gantry module 222 is fixedly supported on the worktable B270. The glue gun fixing plate 221 has glue guns 2210 that correspond one-to-one with the guide grooves 281. The three-axis gantry module 222 is used to drive the glue guns 2210 to move up, down, translate, and move left and right according to the control, that is, to complete the movement along the preset trajectory. At the same time, the glue guns 2210 spray glue to complete the glue application operation.

[0072] The glue quantity control unit mainly includes a glue dispenser 223, a pressure stabilizing valve 224, and a pressure regulating valve A225. The glue outlet of the glue dispenser 223 is connected to the pressure stabilizing chamber of the pressure stabilizing valve 224 through a pipeline. The air outlet 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. The regulating valve A225 is connected to a 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.

[0073] Based on this, in this embodiment, the glue gun 2210 is connected to a pressure single-control line (not shown in the figure). The pressure single-control line is connected to the air source and usually adopts a stop valve structure. The opening and closing size of the stop valve is controlled by the pressure single-control line, thereby further finely controlling the glue dispensing amount.

[0074] In addition, to further improve the quality of the molded rubber ring, a drying mechanism is also provided on the glue coating device 200. This allows the metering shell to be dried after the glue coating is completed. Specifically, there is at least one empty station between the glue coating station and the material picking station, which is the length of the metering shell. The drying mechanism is set on the workbench B270 and is positioned below the empty station. A conventional hot air drying structure can be used, with hot air blowing horizontally across the empty station. The ambient preheating helps to dry and shape the rubber ring on the metering shell, thus avoiding the impact of shaking during the transfer process and preventing the airflow from directly affecting the sealing rubber ring and thus affecting the shape of the device.

[0075] Combination Figures 12 to 17 The adhesive application device 200 also 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 frame A251 supported on the workbench B270. The gantry frame A251 is horizontally arranged above the guide frame 280, and has a stop cylinder A252 corresponding to the guide groove 281. The piston rod of the stop cylinder A252 faces downward and is connected to a baffle plate A253.

[0076] The structure of the stop mechanism B260 is similar to that of the stop mechanism A250, mainly including the gantry frame B261. The difference is that the gantry frame B261 adopts an integral lifting structure, as shown in the figure. Its horizontal plate has sliding cooperation with the vertical plate at both ends and is 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 downwardly extending baffle plate B263. Meanwhile, a detection sensor 265 is set on the gantry frame B261. The detection sensor 265 is set one-to-one with the guide chute 281, that is, one-to-one with the baffle plate B263, and is located upstream of the material receiving baffle plate B263 to detect whether there is a metering shell at the corresponding waiting station. In this embodiment, there is a gap between the waiting station and the material preparation station, which is at least enough for the pusher A2310 to extend. The feed pushes the metering shells waiting at the workstation forward. During operation, when a metering shell is being coated at the glue application station, the piston rod of the stop cylinder B262 retracts, and the baffle B263 descends, blocking the metering shell at the waiting workstation. Simultaneously, when the detection sensor detects that there is a metering shell at the workstation, the piston rod of the stop cylinder A252 corresponding to the same guide trough 281 extends, and the baffle A253 descends to block the metering shell sent by the glue application conveyor line 210. This ensures that there are metering shells at the waiting workstations in each guide trough 281, and that the metering shells are horizontally aligned. Then, they are transferred to the glue application station through the workstation switching mechanism 230. This helps to further improve work efficiency and avoid the occurrence of empty workstations, greatly improving overall reliability.

[0077] In this 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 glue application device and help improve the overall operational reliability of the equipment.

[0078] In the third step of this application, a pallet loading and unloading module is used for automated pallet supply, transfer, and metering shell gripping. For details, please refer to [link / reference needed]. Figures 18 to 29In order to quickly store the metering shells after gluing for subsequent processes in gas meter assembly, a pallet loading and unloading module is provided at the discharge end of the batch gluing device 200. A special pallet 600 for holding the metering shells is also provided. The pallet loading and unloading module mainly includes a pallet supply unit 400 and a pallet transfer unit 500.

[0079] As shown in the figure, the tray 600 includes a plate-shaped body 610. The outer edge of the plate-shaped body 610 has an upwardly bent flange 620 along its thickness direction. The plate-shaped body 610 has a plurality of spaced placement holes 611, which allow the metering shell to be placed with its concave surface facing upward. The outer edge of the metering shell is supported on the plate-shaped body 610. The bottom of the plate-shaped body 610 has at least three evenly distributed support columns 612. The height of the support columns 612 is greater than the depth of the metering shell. This ensures that when the two trays 600 are stacked, the metering shell in the upper tray will not contact the metering shell in the lower tray.

[0080] In this embodiment, the plate-shaped main body 610 is generally rectangular plate-shaped structure, with hand grips 613 at both ends in the length direction, and at least two sets of clamping openings 621 symmetrically arranged in the width direction on the flange 620.

[0081] The pallet 600 has a positioning boss 630 symmetrically arranged along its length near the center. The bottom of the pallet has a positioning groove 640 corresponding to the positioning boss 630. When the two pallets 600 are stacked, the positioning boss 630 of the lower pallet can be inserted into the positioning groove 640 of the upper pallet.

[0082] Furthermore, to further improve the stability of pallet stacking, an inwardly recessed ridge 650 is provided along the outer edge of the bottom of the plate-shaped body 610. The inwardly recessed ridge 650 and the plate-shaped body 610 form a first positioning step. At the same time, the four corners of the plate-shaped body 610 have generally L-shaped positioning pieces 614. The positioning pieces 614 are located inside the inwardly recessed ridge 650 and form a second positioning step with the inwardly recessed ridge 650. The two positioning steps work together to fully ensure the stability of pallet stacking. In addition, the corners of the plate-shaped body 610, the flange 620, the inwardly recessed ridge 650 and the positioning pieces 614 are all rounded. The stepped positioning structure also facilitates the quick alignment and stacking of pallets, as well as the removal of the upper pallet, improving ease of use.

[0083] Key reference Figures 18 to 24In this embodiment, the pallet supply unit 400 mainly includes an empty pallet stacking station 410, a pallet transfer line 420 and an empty pallet gripper assembly 430 corresponding to the empty pallet stacking station. The pallet transfer line 420 includes at least a pallet placement position and a pallet waiting position. The empty pallet gripper assembly 430 can grab the empty pallets in the empty pallet stacking station 410, place them in the pallet placement position, and transport them to the pallet waiting position.

[0084] The pallet transfer unit 500 mainly includes a pallet fixing station and a full-load pallet stacking station 540, as well as a pallet fixing component 510 and a metering shell gripper assembly 520 corresponding to the pallet fixing station, and a full-load pallet gripper assembly 530 for gripping and placing the pallet at the pallet fixing station to the full-load pallet stacking station. The metering shell gripper assembly 520 is used to grip and place the metering shell at the material picking station on the batch gluing device 200 into the pallet at the pallet fixing station.

[0085] Specifically, the pallet supply unit 400 and the pallet transfer unit 500 share a main frame beam structure, which is mainly composed of columns, beams and protective grilles. The pallet supply unit 400 includes a frame B440 fixed on the main frame. The frame B440 includes two horizontally aligned main beams 441 and multiple secondary beams 442 connecting the two main beams 441. The pallet transfer line 420 is fixed on the frame B440 and located between the two main beams 441. It includes two horizontally parallel straight belts. The main beams 441 have guide beams 444. The inner side of the guide beams 444 has vertically arranged rollers 443. The vertical distance between the two horizontally aligned rollers 443 is adapted to the width of the pallet.

[0086] The empty pallet stacking station 410 is located at one end of the pallet transfer line 420 (i.e., the pallet placement position). The empty pallet gripper assembly 430 mainly includes a gripper base A431 for driving the gripper base A431 to rise and fall, and a gripper drive mechanism A432 for horizontal movement between the empty pallet stacking station 410 and the pallet placement position, as shown in the figure. The gripper drive mechanism A432 mainly includes two horizontally arranged X-direction gripper guide rails A4320 and a Y-direction base A4321 that slides with the X-direction gripper guide rails A4320. The X-direction gripper guide rails A4320 cover the empty pallet stacking station 410 and the pallet placement position. In implementation, the X-direction gripper guide rails A4320 are fixed to the top of the main frame beam structure, and the Y-direction base A4321 has... The system includes a Z-axis base A4322 that slides with the gripper base A431. The lower end of the Z-axis base A4322 is fixedly connected to the gripper base A431. Meanwhile, the X-axis gripper guide rail A4320 has an X-axis rack A4323 arranged parallel to it, and an X-axis gear A4324 that meshes with the X-axis rack A4323. The Y-axis base A4321 has an X-axis motor A4325 for driving the X-axis gear A4324 to rotate. The Z-axis base A4322 is vertically arranged, and one side of it has a Z-axis rack A4326 that is fixed and parallel to it. The Z-axis rack A4326 is equipped with a Z-axis gear A4327 that meshes with it. The Y-axis base A4321 has a Z-axis motor A4328 for driving the Z-axis gear A4327 to rotate.

[0087] The gripper base A431 mainly includes a connecting beam A4310 arranged along the length of the pallet transfer line 420. The connecting beam A4310 has at least two horizontally arranged gripper mounting beams A4311. Each gripper mounting beam A4311 has a gripper assembly A installed at its end. The distance between adjacent gripper mounting beams A4311 is an integer multiple of the placement holes 611 on the pallet. In this embodiment, only two gripper mounting beams A4311 are provided, corresponding to the positions of the placement holes at both ends of the pallet. The gripper assembly A mainly includes a horizontally positioned clamping cylinder 4312. The clamping cylinder 4312 is horizontally positioned with its piston rod facing outwards and connected to a pressing cylinder 4313. The pressing cylinder 4313 has its piston rod facing downwards and is equipped with a clamping block 4314, as shown in the figure. The clamping block 4314 is L-shaped, with a bottom contact surface 43140 and a side contact surface 43141. Its slot extends outwards. Pressing blocks 4315 are connected to both lateral ends of the clamping block 4314. There is a gap between the pressing surface of the pressing block 4315 and the bottom contact surface 43140. This gap is typically adapted to the thickness of the object being gripped. In this embodiment, the gap is adapted to the thickness of the pallet. During operation, the gripper drive mechanism A drives the gripper seat A431 to its approximate position, with the gripper assembly A aligned with the placement hole 611. Then, the clamping cylinder 4313 drives the abutment block 4314 downwards until the clamping block 4315 contacts the upper surface of the pallet. Next, the abutment cylinder 4312 drives the abutment block 4314 to move horizontally outwards, so that the bottom contact surface 43140 of the abutment block 4314 contacts the bottom surface of the pallet near the placement hole, while the side contact surface 43141 abuts against the side of the placement hole 611, thereby achieving the gripping of the pallet. This ensures sufficient gripping balance and prevents tilting that could make it difficult to separate the upper and lower pallets.

[0088] In addition, to further improve the adaptability of the gripper base A431, a locking groove 43100 is provided on the connecting beam A4310 along its length. The gripper mounting beam A4311 is fixed to the connecting beam A4310 by locking screws, with the locking screws corresponding to the locking groove 43100. This allows the spacing of the gripper mounting beam A4311 to be adjusted as needed.

[0089] In this embodiment, the other end of the pallet transfer line 420 is a pallet fixing station. The pallet fixing assembly 510 mainly includes two positioning cylinders 511 arranged opposite each other around the pallet fixing station, and a lifting cylinder 512 arranged below the pallet transfer line 420. As shown in the figure, the piston rods of the positioning cylinders 511 are all horizontally inward, and their ends are provided with abutment plates 513. The lifting cylinder 512 is fixed on the sub-beam 442, its piston rod is upward, and it has a horizontally arranged lifting positioning plate 514. Usually, the bottom of the pallet has reinforcing ribs, and the lifting positioning plate 514 has positioning grooves 5130 that are adapted to the position of the reinforcing ribs, ensuring that the position of the pallet in the width direction is not affected by the horizontal force after the pallet is lifted. The lifting positioning plate 514 is located between two straight conveyor belts. During operation, when the pallet reaches this position (i.e., the pallet waiting position, usually detected by a position sensor), the pallet transfer line 420 stops working. The lifting positioning plate 514 is lifted by the lifting cylinder 512, simultaneously lifting the pallet on the straight conveyor belt until it aligns with the position of the clamping plate 513. At this point, the positioning cylinder 511 activates, fixing the pallet in place (in the pallet fixed position) via the clamping plate 513. In this embodiment, the end face of the clamping plate 513 abuts against the side of the pallet's inward-facing protrusion 650, while its upper surface contacts the plate-shaped body 610, providing support and ensuring the stability of the pallet's posture. Then, the lifting cylinder 512 resets, the lifting positioning plate 514 falls, and the pallet transfer line 420 resumes operation, transporting the pallet from the pallet placement position to the pallet waiting position, keeping one pallet in a waiting state, which helps improve production efficiency.

[0090] The metering shell gripper assembly 520 mainly includes a gripper base B521 and a gripper drive mechanism B for driving the gripper base B521 to move up and down and horizontally. The full-load pallet gripper assembly 530 mainly includes a gripper base C531 and a gripper drive mechanism C for driving the gripper base C531 to move up and down and horizontally. In this application, the gripper drive mechanism B and the gripper drive mechanism C are similar in structure to the gripper drive mechanism A. The gripper base B521 has a suction cup gripper 522 that corresponds to the material picking station. The suction cup gripper 522 can move horizontally to the top of the material picking station under the drive of the gripper drive mechanism B, then descend and extend into the groove of the metering shell to pick it up by negative pressure, and then move horizontally to the pallet fixing station. After descending, the metering shell is placed on the pallet of the station.

[0091] The gripper base C531 includes a connecting beam C5310 and multiple gripper mounting beams C5311, as shown in the figure. The gripper mounting beams C5311 and the connecting beams C5310 are both horizontally arranged and perpendicular to each other. Both ends of the gripper mounting beams C5311 are equipped with gripper assemblies C. The gripper assembly C mainly includes a clamping cylinder 5312. The piston rod of the clamping cylinder 5312 faces outward and is connected to a clamping plate 5313, as shown in the figure. In this embodiment, the position of the gripper mounting beam C5311 is adapted to the position of the positioning groove 640 and the clamping opening 621 on the tray. It should be noted that the inner side of the clamping plate 5313 corresponding to the clamping opening 621 has a clamping groove 5314, while the clamping plate 5313 corresponding to the positioning groove 640 only has an inwardly horizontally bent part at the bottom.

[0092] In addition, to further improve the working stability and reliability of the full-load pallet gripper assembly 530, elastic clamping plates 5315 are provided on the gripper mounting beams C5311 at both ends. In this embodiment, there are at least two elastic clamping plates 5315, which are diagonally distributed. The elastic clamping plates 5315 are fixed to the gripper mounting beams C5311 by elastic connectors 5316. The elastic clamping plates 5315 are three-sided and have outwardly sloping flanges at the bottom. When the pallet in the pallet fixing position is filled with the metering shell, the full-load pallet gripper assembly 530 starts to work. The gripper seat C531 descends facing the full-load pallet and first contacts and presses against the upper surface of the pallet. Then, the gripper assembly C clamps the two sides of the pallet. Then, the gripper drive mechanism C rises and moves horizontally to the full-load pallet stacking station. Multiple full-load pallets are stacked up and down in sequence to facilitate subsequent rapid transfer.

[0093] As shown in the figure, the gripper drive mechanism C532 has a similar structure to the gripper drive mechanism C532. The gripper drive mechanism C532 mainly includes two horizontally arranged X-direction gripper guide rails C5320 and a Y-direction base C5321 that slides with the X-direction gripper guide rails C5320. The X-direction gripper guide rails C5320 cover the pallet fixing station and the full-load pallet stacking station 540. The Y-direction base C5321 has a Z-direction base C5322 that slides with it. The lower end of the Z-direction base C5322 is fixedly connected to the gripper base C531. In implementation, the X-direction gripper guide rails C5320 are fixed to the top of the main frame beam structure. Simultaneously, the X-direction gripper guide rails... The rail C5320 has an X-axis rack C5323 arranged parallel to it, and an X-axis gear C5324 meshing with the X-axis rack C5323. The Y-axis base C5321 has an X-axis motor C5325 for driving the X-axis gear C5324 to rotate. The Z-axis base C5322 is arranged vertically, and its lower end is fixedly connected to the connecting beam C5310. On one side of the Z-axis base C5322, there is a Z-axis rack C5326 fixed to and parallel to it. The Z-axis rack C5326 is equipped with a Z-axis gear C5327 meshing with it. The Y-axis base C5321 has a Z-axis motor C5328 for driving the Z-axis gear C5327 to rotate.

[0094] refer to Figures 1 to 29 As shown, in the rapid production method of diaphragm gas meter casing, during equipment assembly, the end of transfer conveyor line A310 away from the ramp section 311 is connected to the discharge port 110. Transfer conveyor line B320 is flush with or slightly higher than the glue coating conveyor line 210. The glue coating conveyor line 210 and the feeding mechanism 330 are located on both sides of the width direction of transfer conveyor line B320, respectively. The position and number of pusher plates 335 correspond one-to-one with the glue coating conveyor line 210. The material preparation station, waiting station, glue coating station and material picking station are distributed sequentially along the direction away from the transfer module 300. The empty pallet stacking station and the full-load pallet stacking station are set in parallel, but the entrance openings of the stations are perpendicular to each other to avoid operational interference.

[0095] In the specific implementation process, the metering shell formed by the metering shell punch press 100 is sent out with the concave side facing down. After passing through the transfer module 300, it enters the glue coating conveyor line 210 with the concave side facing up. After passing through the material preparation station and the waiting station in sequence, it arrives at the glue coating station. The glue coating mechanism 220 works to perform the glue coating operation. In order to improve the glue coating quality, two glue coating methods are given. Usually, the sealing ring of the metering shell is a rectangular closed loop, including a short side and a long side, where the length of the short side is a. During the glue coating process, the glue coating starts from the position near the middle of the short side. The glue output increases linearly and reaches a stable glue output Q within the stroke L. When the glue coating reaches the initial spraying position, the glue output decreases linearly in the same way and decreases to zero within the stroke L, where L≤a / 2.

[0096] Because there is usually a rounded chamfer section between the short and long sides, in another embodiment, during the adhesive application process, the adhesive is applied from the middle position of the rounded chamfer section with a stable amount of adhesive Q. The adhesive application is stopped when the trajectory returns to the initial spraying position. In short, the joint point is placed on the rounded chamfer section, which can increase the adhesion effect of the joint point and thus improve the shaping quality of the adhesive ring.

[0097] After the glue application is completed, the metering shell moves to the picking station and is picked up by the metering shell gripper assembly 520 and placed on the pallet in the pallet fixing position. When the pallet in the pallet fixing position is full of metering shells, the full-load pallet gripper assembly 530 starts to work and picks up the pallet and places it in the full-load pallet stacking position.

[0098] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
