Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, specifically to a tooling and fixture system for an automated gas meter production line that is compatible with various types of civilian gas meters and requires no adjustment. Background Technology

[0002] In the field of residential gas meter manufacturing, gas meters currently on the market are mainly classified into diaphragm gas meters and ultrasonic gas meters according to their metering methods. These two categories differ significantly in appearance and structure, with notable variations between products from different manufacturers. Even within the same manufacturer, the appearance may be adjusted during product iterations. Gas meters are mandatory measuring instruments under national regulations, and their testing and verification requirements strictly adhere to relevant laws and regulations and national metrological verification procedures. The core principle is "mandatory verification upon first use, limited-term use, and replacement upon expiration."

[0003] Currently, domestic gas meter manufacturers generally adopt a "one model, one tooling" model: each gas meter model requires a dedicated tooling, necessitating machine shutdown, manual disassembly of the old tooling, installation of the new tooling, or adjustment of the tooling and recalibration of the vision camera and probe positions during model changeovers. According to the "2025 Gas Metering Equipment White Paper" by the China Urban Gas Association, the average time for a single model changeover on mainstream production lines is 42 to 58 minutes, resulting in a 18%–25% decrease in overall equipment efficiency (OEE), severely restricting the ability to respond to small-batch, multi-variety orders. Existing technology lacks an adjustment-free, compatible gas meter tooling and fixture system that can meet the needs of various residential gas meters in logistics, transportation, assembly, and testing during production. Therefore, we propose an adjustment-free, compatible tooling and fixture system for automated gas meter production lines. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a tooling and fixture system for automated gas meter production lines that is compatible with multiple types of residential gas meters without the need for adjustment. This system offers excellent tooling and fixture compatibility, allowing a single tooling and fixture to support multiple types of meters, significantly reducing equipment and management costs. When changing production orders for different gas meters, it greatly improves production efficiency and reduces production costs. Furthermore, the tooling and fixtures of this invention are suitable for both manual and automated production, reducing the repetitive investment required for gas meter manufacturers and testing institutes to upgrade automation. This effectively solves the problems mentioned in the background art.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The tooling and fixture system in this automatic gas meter production line, which is compatible with various types of residential gas meters and requires no adjustment, has the following advantages:

[0020] 1. Analyzing the commonalities of residential gas meters on the market, we designed a highly compatible adaptive gripper mechanism, along with three types of tooling trays: inclined tooling components, inverted tooling components, and hanging tooling components, as well as an adjustable-spacing test bench connector. This allows a single tooling and fixture to be compatible with multiple types of meters, solving the pain point that gas meter manufacturers and testing institutes need to use a dedicated set of tooling and fixtures for each type or several types of meters, thus greatly reducing equipment and management costs.

[0021] 2. The adaptive gripper mechanism transfers the gas meter by grasping its connector. The inclined, inverted, and hanging tooling components are designed based on the common features of existing gas meters. Meanwhile, the two tooling seats of the battery compartment power supply interface mechanism correspond to the rows and columns of the gas meter battery compartment, respectively. When changing production orders for different gas meters, there is no need to change tooling or fixtures or make manual adjustments, which greatly improves production efficiency and reduces production costs.

[0022] 3. The adaptive gripper mechanism features a floating design and adjustable-spacing gripper cylinders. The integrated testing station adjusts the spacing between the two testing station connectors in the same group through the cooperation of the drive and driven components. The acquisition head mounting bracket can perform XYZ three-axis translation. The inclined, inverted, and hanging tooling components are suitable for different working conditions, making them suitable for both manual and automated production, reducing the repetitive investment of gas meter manufacturers and testing institutes in upgrading automation.

Detailed Implementation

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please see Figure 1-28This embodiment provides a technical solution: a tooling fixture system for automatic gas meter production lines that is compatible with various types of civilian gas meters without adjustment. It includes a container 1, which is stacked. A robot is placed near the container 1 to work with it. The input end of the robot is electrically connected to the output end of the main controller of the tooling fixture system. The robot moves with an adaptive gripper mechanism 2. The movement trajectory is determined by the built-in program of the main controller of the tooling fixture system. The gas meter is moved by gripping the connector of the gas meter 4 placed on the container 1. The gas meter is moved by gripping the connector of the gas meter 4 placed on the container 1. The device utilizes the commonality of various shapes of meters, all of which have connectors and the connectors have standard control. Thus, the adaptive gripper mechanism 2 of this invention can realize the gripping and moving of all current civilian gas meters. The device also includes the adaptive gripper mechanism 2, a conveyor 3, an integrated testing table 10, and a battery compartment power supply interface mechanism 11.

[0054] Adaptive gripper mechanism 2: It includes a connecting flange 21, a gripper frame 22, single gripper assemblies 26, and an opening / closing drive cylinder 27. The connecting flange 21 is fixedly connected to the front end of the robot. The gripper frame 22 is fixedly connected to the lower end of the connecting flange 21. The lower end of the gripper frame 22 is provided with evenly distributed single gripper assemblies 26. The opening / closing drive cylinder 27 is fixedly connected to the right end of the gripper frame 22. The opening / closing drive cylinder 27 works in conjunction with the rightmost single gripper assembly 26 to open / close the gripper. The air inlet of the pneumatic cylinder 27 is connected to an external air pump. The adaptive gripper mechanism 2 also includes a fixed connecting block 23, a connecting rod 24, and a guide rail 25. The fixed connecting block 23 is fixedly connected to the front and rear ends of the left side of the gripper frame 22. The front and rear ends of the right side of the gripper frame 22 are both fixedly connected to the guide rail 25. The lower end of the guide rail 25 is slidably connected to evenly distributed sliders. The single gripper assembly 26 is respectively disposed between the adjacent sliders and between the two fixed connecting blocks 23. Each of the two adjacent single-grip components 26 is connected by a connecting rod 24. The gas meter 4 is close to the container 1 to improve space utilization. After being removed from the container 1, when placed on the tooling tray, the distance between the meters is larger to ensure sufficient space for the robot gripper to pick up the meters from the side in the subsequent process. Therefore, the adaptive gripper mechanism 2 of this invention is used. When the adaptive gripper mechanism 2 picks up the gas meter 4 from the container 1, the opening and closing drive cylinder 27 is in the retracted state, and the single-grip components 26 are close to each other. When the meter is placed on the tooling tray after being picked up, the telescopic end of the opening and closing drive cylinder 27 extends, and the distance between the single-grip components 26 is increased. Then the meter is placed on the tooling tray. When the telescopic end of the opening and closing drive cylinder 27 extends, it is transmitted through the first mounting plate 261 on the right and the connecting rod 24. The first mounting plate 261 slides on the lower end of the guide rail 25 and finally reaches the state of equal distance opening. Conversely, when the telescopic end of the opening and closing drive cylinder 27 retracts, the first mounting plate 261 will close.

[0055] The single-hand gripper assembly 26 includes a first mounting plate 261, a first lifting cylinder 262, a chain 263, a gripper cylinder mounting plate 264, a gripper cylinder 265, a limit plate 266, and a detection photoelectric sensor 267. The first mounting plate 261 is fixedly connected between adjacent front and rear sliders and between two fixed connecting blocks 23. The left ends of the connecting rods 24 are all round holes, and the connecting rods 24 are connected to the adjacent first mounting plate 261 on the left side by threaded pins. The right ends of the connecting rods 24 are all oblong holes, and the right ends of the connecting rods 24 are connected to the adjacent first mounting plate 261 on the right side by threaded pins. There is a reasonable gap between the threaded pins and the round holes and oblong holes of the connecting rods 24. The threaded pins located in the oblong holes of the connecting rods 24 are all close to the adjacent oblong holes. The inner wall slides through the cylinder 27. The right end of the telescopic end of the cylinder 27 is fixedly connected to the upper surface of the rightmost first mounting plate 261 via a connector. A first lifting cylinder 262 is fixedly connected to the upper surface of the first mounting plate 261. A connector 2 is fixedly connected to the upper end of the telescopic end of each first lifting cylinder 262. Chains 263 are fixedly connected to the four corners of the lower surface of the connector 2. The lower ends of the chains 263 pass through adjacent through holes in the first mounting plate 261. A gripper cylinder mounting plate 264 is fixedly connected between the lower ends of the four chains 263 on the same first mounting plate 261. Gripper cylinders 265 are fixedly connected to the middle of the lower surface of the gripper cylinder mounting plate 264. Anti-slip fingers are fixedly connected to the guide rods at both ends of the gripper cylinders 265. Limiting plates 266 are fixedly connected to both ends of the lower surface of mounting plate 261. Each limiting plate 266 is a triangular plate. Limiting grooves are provided at both ends of the gripper cylinder mounting plate 264. Each limiting plate 266 engages with a vertically adjacent limiting groove. A detection photoelectric sensor 267 is fixedly connected to the lower end of each gripper cylinder mounting plate 264. The detection photoelectric sensor 267 is bidirectionally electrically connected to the main controller of the tooling fixture system. The air inlets of each gripper cylinder 265 are connected to an external air pump. When gripping the connector of gas meter 4, as the extension end of the first lifting cylinder 262 retracts, the connecting piece 2 and the chain 263 descend synchronously. The entire assembly of the gripper cylinder mounting plate 264 and the gripper cylinder 265 becomes floating under the constraint of the limiting plates 266. At this point, the assembly consisting of the gripper cylinder mounting plate 264 and the gripper cylinder 265 has six degrees of freedom: X / Y / Z translation and rotation around the X / Y / Z axes. The limiting plate 266 is a triangular plate, and its lower end is inside the limiting groove of the gripper cylinder mounting plate 264, thus ensuring both floating capability and preventing overturning. When the assembly consisting of the gripper cylinder mounting plate 264 and the gripper cylinder 265 is in a floating state, the anti-slip fingers of the gripper cylinder 265 can adaptively adjust according to the attitude of the meter. After the anti-slip fingers are adaptively adjusted to the correct position, the gripper cylinder 265 closes, clamping the gas meter connector. The anti-slip fingers are made of polyurethane or other anti-slip materials. After the gripper cylinder 265 closes, the anti-slip material firmly clamps the connector of the gas meter 4.The photoelectric sensor 267 is a photoelectric switch that detects the presence of a target object by emitting a light beam and detecting changes in the beam. When the gas meter 4 is gripped, the gripper cylinder 265 rises. If no meter is detected, the main controller of the tooling fixture system prompts the robot to pause and sound an alarm. After the gas meter 4's connector is gripped, the telescopic end of the first lifting cylinder 262 extends, the chain 263 rises, and the first mounting plate 261 and the gripper cylinder mounting plate 264 come into contact. At this time, the gripper cylinder mounting plate 264 has no degrees of freedom, so the gas meter 4 will not shake during movement, and adjacent meters will not collide and damage the meters.

[0056] Conveyor 3: Its upper end is provided with a tooling tray mechanism 5, which includes an inclined tooling assembly 51, an inverted tooling assembly 52, and a hanging tooling assembly 53. Gas meters 4 are provided at the upper ends of the inclined tooling assembly 51, the inverted tooling assembly 52, and the hanging tooling assembly 53. A tray blocker 6 is fixedly connected to the end of the conveyor 3. The robot transfers the gas meters 4 to the upper end of the conveyor 3 and places them into the corresponding tooling. Then, the gas meters 4 are transported with the corresponding tooling to the subsequent assembly or inspection process. The conveyor 3 is a commonly used conveying mechanism in the prior art. It can be driven by a conveyor belt or a push rod. The tray blocker 6 can be a baffle, a baffle bar, or a device used to block various tooling. Its function is to block various tooling at the transfer position so that the robot gripper used for transfer can grasp the tooling.

[0057] The inclined fixture assembly 51 includes an inclined fixture 511, a gripper opening 512, a central recess 513, and two side limiting bosses 514. The inclined fixture 511 is placed between the rollers of the conveyor 3. The gas meter 4 is placed inside the inclined fixture 511. The lower surface of the gas meter 4 is in contact with the adjacent coplanar plane α of the inclined fixture 511. The angle between the coplanar plane α and the lower surface of the inclined fixture 511 is 45°. The angle between the coplanar plane α and the bottom support surface of the inclined fixture 511 where the gas meter 4 is placed is 90°. A central recess 513 is provided in the middle of the coplanar plane α. Two side limiting bosses 514 are provided on the left and right sides of the coplanar plane α. The gas meter 4 is located between the two side limiting bosses 514. The lower left and right sides of the bottom support surface of the inclined fixture 511 are... Both sides are equipped with gripper openings 512. The gas meters 4 produced by domestic manufacturers are either diaphragm gas meters or ultrasonic gas meters. The rotary volume of diaphragm gas meters varies; the standard is 1.2L, but there are also 0.8L and 0.9L models. The size of the meters differs depending on the rotary volume, but all meters share a common characteristic: the bottom is either flat or can form a flat surface, and the back is either flat or a large-angle curved surface. The bottom and back surfaces generally form a 90° angle. Utilizing this common feature, the angle between the coplanar plane α of the inclined fixture 511 and the bottom support surface of the inclined fixture 511 is 90°; the angle between the coplanar plane α and the lower surface of the inclined fixture 511 is 45° for optimal effect. Thus, under the influence of gravity, the gas meter 4 can be positioned by contacting the fixture through its bottom and back. The purpose is to ensure that the center of gravity of various meters is on the tray and will not tip over, and also to facilitate manual inspection of the front of the meter or operation from the front of the meter. The back of most gas meters 4 is large-format, so a concave design 513 is incorporated into the support section of the inclined fixture 511 to prevent the back from tilting. This ensures that when the large curved back contacts the back of the fixture, theoretically, only the two lines on either side will contact, resulting in stability and no shaking. After the gas meter 4 is placed on the inclined fixture 511, 5 out of its 6 spatial degrees of freedom are constrained, leaving only its position along the width of the tray undefined. There are two reasons for this: first, the left and right positions may exceed tolerances when the meter is placed by a robot or manually; second, the meter may move back and forth during transport due to stops, inertia, etc., thus affecting the position of the meter on either side of the fixture. The design incorporates two side limiting bosses 514, ensuring that the meter will not slide out of the side limiting bosses 514 during normal transport. Simultaneously, the design incorporates a gripper cylinder 265 that grips the meter from the tray; when opened, its width exceeds the inner dimensions of the adjacent side limiting bosses 514. During the gripping process, the gripper cylinder 265 also determines the previously undefined sixth degree of freedom, thus ensuring high consistency in spatial positioning of the gas meter gripped by the robot from the inclined fixture 511, meeting the accuracy requirements of subsequent assembly / inspection processes. On both sides of the inclined fixture 511, gripper openings 512 are designed to facilitate manual or robotic gripping of the inclined fixture 511 when they are placed side-by-side on the conveyor 3.

[0058] The reversing fixture assembly 52 includes a fixture base plate 521, a connector limiting sleeve 522, and holes 523. The fixture base plate 521 is placed between the rollers of the conveyor 3. Holes 523 are provided on both the left and right sides of the fixture base plate 521. The connector limiting sleeves 522, which are symmetrically distributed front and back, are fixedly connected to the middle of the fixture base plate 521. The distance between the two connector limiting sleeves 522 located on the same fixture base plate 521 is 130mm. The inner hole of the connector limiting sleeve 522 is designed to be φ30mm. When using the reversing fixture assembly 52, the connector of the gas meter 4 is inserted between the two connector limiting sleeves 522 located on the same fixture base plate 521. The upper end of the inner hole of the connector limiting sleeve 522 is designed with a chamfer to facilitate the insertion of the connector of the gas meter 4. The material of the connector limiting sleeve 522 is selected as nylon, bakelite, or other plastics with good mechanical properties, which will not scratch the connector of the gas meter 4. The connector limiting sleeve 522 can be replaced after wear.

[0059] The hanging fixture assembly 53 includes a bottom cover plate 531, springs 532, engagement joint threaded pressure plates 533, and a fixture pallet base plate 534. The fixture pallet base plate 534 is placed between the rollers of the conveyor 3. The bottom cover plate 531 is fixedly connected to the center of the lower surface of the fixture pallet base plate 534. Pressure plate holes are opened on both the left and right sides of the fixture pallet base plate 534. Springs 532 are symmetrically distributed front and back between the left and right side walls of the pressure plate holes. Engagement joint threaded pressure plates 533 are provided between two springs 532 located on the same side of the same pressure plate hole. The left and right side wings of the engagement joint threaded pressure plates 533 are slidably connected to the lower surface of the fixture pallet base plate 534. M30×2 threads are opened in the middle of the two engagement joint threaded pressure plates 533 located in the same pressure plate hole. Fixed grooves are opened between the front and rear ends of the engagement joint threaded pressure plates 533. The through holes and the threaded pressure plates 533 of the engagement joint are used in conjunction with the vertically adjacent bottom cover plates 531. When using the hanging tooling assembly 53, the inner side of the threaded pressure plate 533 of the engagement joint is threaded with the gas meter 4 connector. The two threaded pressure plates 533 of the engagement joint are installed symmetrically and closed by the elastic force of the spring 532. When closed, they do not form a complete circle, but are designed to clamp the connector. The engagement joint threaded pressure plates 533 of the engagement joint are provided with positioning through holes between the front and rear ends. The external power mechanism can open the two threaded pressure plates 533 of the engagement joint located in the same pressure plate hole by inserting into the positioning through holes, that is, to allow the two threaded pressure plates 533 of the engagement joint from closed to open, so that the gas meter 4 connector can be inserted. The tooling tray base plate 534 has a hole in the middle through which the gas meter 4 connector can pass. The tooling tray base plate 534 is fixed to the lower end of the bottom cover plate 531. There is a 1mm gap between the upper surface of the tooling tray base plate 534 and the vertically adjacent meshing joint threaded pressure plate 533, so that the meshing joint threaded pressure plate 533 can float up and down inside the pressure plate hole of the tooling tray base plate 534. Because the thread starting point of each gas meter 4 connector will be different, but the thread starting point on the meshing joint threaded pressure plate 533 is fixed, and the thread pitch is 2mm, half a turn is 1mm. Without this 1mm floating gap, the thread of the meshing joint threaded pressure plate 533 cannot guarantee that it will mesh with the thread of the gas meter 4 connector every time.

[0060] Integrated testing station 10: It is equipped with a front information acquisition mechanism 7, a joint spacing automatic adjustment mechanism 8 and a lifting tooling mechanism 9 from top to bottom;

[0061] The front information acquisition mechanism 7 includes a Z-axis lifting assembly 71, a front-to-back displacement electric cylinder 72, and an X-axis translation assembly 73. The Z-axis lifting assembly 71 includes a second mounting plate 711, a linear guide rail 712, a transmission rod 713, a Z-axis crossbeam 714, and a second guide rail 715. The second mounting plate 711 is fixedly connected to the upper front side of the integrated testing table 10 bracket. The linear guide rail 712 is fixedly connected to the front side of the second mounting plate 711. The transmission rod 713 is fixedly connected to the front side of the slide of the linear guide rail 712. The lower end of the transmission rod 713 is rotatably connected to the Z-axis crossbeam 714 through a fisheye joint. The left and right ends of the integrated testing table 10 bracket are both fixedly connected to the second guide rail 715. The left and right ends of the Z-axis crossbeam 714 are slidably connected to the adjacent second guide rail 715 through a second slider. The upper end of the Z-axis crossbeam 714 is fixedly connected to the front-to-back displacement electric cylinder 72. The X-axis translation assembly 73 includes a left-to-right displacement electric cylinder 731 and a third guide rail 732. The X-axis beam 733 and the acquisition head mounting bracket 734 are connected together. The middle of the X-axis beam 733 is fixedly connected to the left and right symmetrically distributed sliders. The rear end of the telescopic end of the front and rear displacement electric cylinder 72 is fixedly connected to the guide rail 732. The sliders are all slidably connected to the rear end of the guide rail 732. The left and right displacement electric cylinders 731 are fixedly connected to the left side of the X-axis beam 733. The right side of the telescopic end of the left and right displacement electric cylinders 731 is fixedly connected to the left end of the guide rail 732. The upper surface of the X-axis beam 733 is fixedly connected with evenly distributed acquisition head mounting brackets 734. The air inlets of the left and right displacement electric cylinders 731 and the front and rear displacement electric cylinders 72 are both connected to an external air pump. The input end of the linear guide 712 is electrically connected to the output end of the main controller of the tooling fixture system. When acquiring the front information of the gas meter 4, the slide of the linear guide 712 drives the transmission rod 713 and the Z-axis beam 714 to move up and down as a whole. The Z-axis beam 714 slides up and down between the two guide rails 715 to limit the movement of the Z-axis beam 714. The front and rear displacement electric cylinders 72 drive the X-axis translation component 73 to move back and forth. Limiting post components can be set at the left and right ends of the front and rear displacement electric cylinders 72. The limiting posts move back and forth synchronously with the guide rails 732 to control the movement of the front and rear displacement electric cylinders 72. Radial protection is achieved by extending the telescopic end of the left-right displacement electric cylinder 731, allowing the X-axis beam 733 and slider three to slide to the right at the rear end of guide rail three 732, thus shifting the entire acquisition head mounting bracket 734 to the right. Simultaneously, the telescopic end of the left-right displacement electric cylinder 731 retracts, shifting the entire acquisition head mounting bracket 734 to the left. Radial protection for the left-right displacement electric cylinder 731 is achieved through the limiting action of slider three and guide rail three 732. The number of acquisition head mounting brackets 734 can be set according to requirements. Visual cameras, near-photoelectric acquisition heads, and other signal acquisition devices required for gas meter detection can be mounted on the brackets. In summary, the Z-axis can move the X and Y axes vertically, the Y-axis can move the X-axis forward and backward, and the X-axis can move the signal acquisition device in front of each detection position horizontally.This allows the signal collector to move along the ZYZ three axes in front of each gas meter, eliminating the need for manual adjustment of the signal collector's position when switching between different meters.

[0062] The automatic joint spacing adjustment mechanism 8 includes a frame 81, a drive assembly 82, a detection table joint 83, a guide rail 84, a slider 85, a connecting rod 86, and a driven assembly 87. The frame 81 is fixedly connected to the upper part of the integrated detection table 10 bracket. The drive assembly 82 is located on the lower left side of the frame 81, and the driven assembly 87 is located on the lower right side of the frame 81. The guide rail 84 is fixedly connected to the middle of the lower end of the frame 81. Twelve evenly distributed sliders 85 are slidably connected to the lower end of the guide rail 84. The front side of each slider 85 is fixedly connected to a detection table joint 83. The upper surfaces of two even-numbered adjacent detection table joints 83 from left to right and the upper surfaces of two odd-numbered adjacent detection table joints 83 from left to right are connected to each other. The lower surfaces of the test joints 83 are connected to connecting rods 86 via threaded pins. There are appropriate gaps between the threaded pins and the round holes at both ends of the connecting rods 86. The two leftmost test joints 83 are used in conjunction with the drive assembly 82, and the two rightmost test joints 83 are used in conjunction with the driven assembly 87. The drive assembly 82 is used in conjunction with an external power supply. When the gas meter 4 is being tested, the two joints are aligned with a set of test joints 83 on the test platform. The drive assembly 82 consists of a motor, a reducer, a synchronous belt, two synchronous pulleys, and its control system. The driven assembly 87 consists of a synchronous belt and two synchronous pulleys. The test joints 83 at even-numbered positions from left to right and those at odd-numbered positions from left to right... All the test bench joints 83 are connected as a whole by connecting rod 86. The upper surface of the second test bench joint 83 from left to right is fixedly connected to the upper end of the synchronous belt of the drive assembly 82, and the lower surface of the first test bench joint 83 from left to right is fixedly connected to the lower end of the synchronous belt of the drive assembly 82. The upper surface of the first test bench joint 83 from right to left is fixedly connected to the upper end of the synchronous belt of the driven assembly 87, and the lower surface of the second test bench joint 83 from right to left is fixedly connected to the lower end of the synchronous belt of the driven assembly 87. Every two test bench joints 83 from left to right form a group. The synchronous belt of the drive assembly 82, the synchronous belt of the driven assembly 87, and all the test bench joints 83 form a whole transmission system. When the drive... When the output shaft of the motor of component 82 rotates counterclockwise from the front view, the even-numbered detection platform connectors 83 from left to right slide to the left at the lower end of guide rail 4 84. The upper end of the synchronous belt of driven component 87 moves to the left synchronously, and the lower end of the synchronous belt of driven component 87 moves to the right synchronously. This causes the odd-numbered detection platform connectors 83 from left to right to slide to the right at the lower end of guide rail 4 84. The two detection platform connectors 83 in the same group move closer to each other. When the output shaft of the motor of drive component 82 rotates clockwise from the front view, the two detection platform connectors 83 in the same group move away from each other. This enables the automatic and precise adjustment of the spacing of the detection platform connectors 83 to match the spacing of the gas meter 4 connectors when testing gas meters 4 with different spacing connectors.

[0063] The lifting fixture mechanism 9 includes a lifting fixture mounting plate 91, a second lifting cylinder 92, a fixture plate 93, corrugated suction cups 94, and air pipe connectors 95. The lifting fixture mounting plates 91 are uniformly fixedly connected to the lower part of the integrated testing table 10 bracket. Two adjacent lifting fixture mounting plates 91 form a group. A cylinder seat is fixedly connected between the upper ends of two lifting fixture mounting plates 91 in the same group. A second lifting cylinder 92 is fixedly connected to the middle of the lower surface of each cylinder seat. A fixture plate 93 is fixedly connected between the upper ends of the telescopic ends of the second lifting cylinder 92. Corrugated suction cups 94 are symmetrically distributed on the upper surface of each fixture plate 93. Two air pipe connectors 95 are fixedly connected to the front side of each fixture plate 93. The air pipe connectors 94 are respectively connected to the adjacent corrugated suction cups 94 on the rear side. The suction cup 94 is connected, and the air inlet of the air pipe connector 95 is connected to the air port of the external vacuum generator. The air inlet of the second lifting cylinder 92 is connected to the air outlet of the external air pump. The working process of the lifting fixture mechanism 9 is as follows: the external vacuum generator is started, and the vacuum adsorption is opened → the gas meter 4 is placed on the fixture plate 93 by the automatic gripper, and the gripper leaves → the extension end of the second lifting cylinder 92 pushes out, and the gas meter 4 rises with the fixture plate 93 until the connector of the gas meter 4 contacts and is tightly pressed against the connector 83 of the test bench, and the vacuum is closed → the test bench performs the test → after the test is completed, the vacuum is opened and the corrugated suction cup 94 sucks the meter again → the extension end of the second lifting cylinder 92 descends → the automatic gripper grabs the gas meter 4 on the fixture plate 93 → the vacuum adsorption is closed → the automatic gripper moves the meter away.

[0064] Battery compartment power supply interface mechanism 11: It includes a 4-row, 1-column fixture base 111 and a 2-row, 2-column fixture base 114, which are respectively disposed inside the battery compartment of the gas meter 4. The battery compartment power supply interface mechanism 11 also includes a first elastic electrode sheet 112, an first electrode lead 113, a second elastic electrode sheet 115, and a second electrode lead 116. The 4-row, 1-column fixture base 111 and the 2-row, 2-column fixture base 114 are both nylon fixture bases. The side of the 4-row, 1-column fixture base 111 away from the gas meter 4 is connected by screws to the upper and lower distributed elastic electrode sheets 112. The first elastic electrode sheet 112 is "U" shaped. Electrode leads 113 are fixedly connected to the middle of each of the 12. On the left and right sides of the 2-row, 2-column fixture 114 away from the gas meter 4, elastic electrode plates 115 are connected by screws. The elastic electrode plates 112 are "B"-shaped. Electrode leads 116 are fixedly connected to the ends of the elastic electrode plates 112 away from the gas meter 4. Electrode leads 113 and 116 are used with an external power source. When testing a gas meter 4 with a 4-row, 1-column battery compartment, the elastic electrode plate 112 is "U"-shaped. When inserted, the lower end of the elastic electrode plate 112 is subjected to an inward force, allowing it to deform inward, facilitating the insertion of the 4-row, 1-column battery compartment. The fixture 111 is placed into the battery compartment. After placement, the external force is removed, and the elastic electrode sheet 112 recovers its deformation under its own elasticity, thus locking itself in the battery compartment. This achieves both the fixation of the 4-row, 1-column fixture 111 in the battery compartment and the connection of the positive and negative contacts of the gas meter 4. One end of each of the two electrode leads 113 is connected to one of the two elastic electrode sheets 112, and the other end is connected to a 6V DC programmable switching power supply. Whether each lead is positive or negative can be controlled by the system. When installing the gas meter 4 into the 2-row, 2-column battery compartment, the four elastic electrode sheets 115 are fixed to the 2-row, 2-column fixture 114 with screws. The lower end of 114 is narrow, and the lower end of the elastic electrode sheet 115 is subjected to an inward force, which allows it to deform inward, making it easy to place the 2-row 2-column fixture 114 into the battery compartment. After placement, the external force is removed, and the elastic electrode sheet 115 recovers its deformation under its own elasticity, thus locking itself in the battery compartment. This not only fixes the 2-row 2-column fixture 114 in the battery compartment but also connects the positive and negative contacts of the gas meter 4. One end of the four electrode leads 116 is connected to the four elastic electrode sheets 115 respectively, and the other end is connected to a 6V DC programmable switching power supply. The two leads on the left are connected to one circuit, and the two leads on the right are connected to the other circuit. Whether each lead is connected to the positive or negative terminal can be controlled by the system.

[0065] The working principle of the tooling fixture system for automatic gas meter production line provided by the present invention, which is compatible with various types of civilian gas meters without adjustment, is as follows: The robot moves with the adaptive gripper mechanism 2. The movement trajectory is determined by the built-in program of the main controller of the tooling fixture system. By gripping the connector of the gas meter 4 placed on the container 1, the gas meter is transported. It utilizes the commonality of various shapes of meters, all of which have connectors and the connectors have standard control. In this way, the adaptive gripper mechanism 2 of the present invention can realize the gripping and transport of all current civilian gas meters.

[0066] The rear end of the assembly consisting of the connecting flange 21 and the gripper frame 22 is equipped with a gripper for gripping the container 1. This allows the automatic gripper to grab the container 1 after grabbing the gas meters 4 of one layer during the automated production process, and then grab the meters of the next layer. The gripper consists of a telescopic column with a compression spring and a gripper. The two ends of the gripper are driven by the robot to insert into the adjacent clearance groove in the middle of the container 1. The lower end of the gripper is equipped with a barb that is locked into the lower end of the container 1 to grip the container 1. At this time, the gripping position is biased to one side of the container 1. The telescopic column with the compression spring presses down on the side of the container 1 that has a tendency to tilt due to the elastic potential energy of the compression spring, so that the container 1 is kept balanced. The compression spring can be regularly maintained and replaced by unscrewing the nut at the lower end of the telescopic column.

[0067] When gripping the connector of gas meter 4, as the telescopic end of the first lifting cylinder 262 retracts, the connecting piece 2 and the chain 263 descend synchronously. The whole assembly consisting of the gripper cylinder mounting plate 264 and the gripper cylinder 265 becomes floating under the constraint of the limiting plate 266. At this time, the whole assembly consisting of the gripper cylinder mounting plate 264 and the gripper cylinder 265 has 6 degrees of freedom, including X / Y / Z translation and rotation around the X / Y / Z axes. The limiting plate 266 is a triangular plate, and the lower part of the limiting plate 266 is still inside the limiting groove of the gripper cylinder mounting plate 264, thus ensuring both floating capability and preventing overturning.

[0068] Due to various factors, the position of the meter on the container, or the position of the entire stack during automatic unstacking in the next section, will have errors. For example, when palletizing via AGV, the position error is about ±10mm. In some cases, the meter is not within the limit frame on the container, but part of the meter is on the step of the limit frame, so the meter is tilted. When the whole assembly of the gripper cylinder mounting plate 264 and the gripper cylinder 265 is in a floating state, the anti-slip fingers of the gripper cylinder 265 can adaptively adjust according to the posture of the meter. After the anti-slip fingers are adaptively adjusted to the correct position, the gripper cylinder 265 closes and clamps the gas meter connector. The anti-slip fingers are made of anti-slip materials such as polyurethane. After the gripper cylinder 265 closes, the anti-slip material can firmly clamp the connector of the gas meter 4. The photoelectric sensor 267 is a photoelectric switch that senses the presence of the target object by emitting a beam and detecting changes in the beam. After the gas meter 4 is clamped, the gripper cylinder 265 rises. If no meter is detected, the main controller of the tooling fixture system will control the robot to pause and sound an alarm.

[0069] After clamping the connector of gas meter 4, the telescopic end of the first lifting cylinder 262 extends, the chain 263 rises, and the first mounting plate 261 and the clamping cylinder mounting plate 264 are in contact. At this time, the clamping cylinder mounting plate 264 has no degree of freedom, so the gas meter 4 will not shake during the movement, and there will be no collision or damage between adjacent meters.

[0070] The gas meters 4 are close together on the container 1 to improve space utilization. After being removed from the container 1, the distance between the meters is larger when they are placed on the tooling tray. This is to ensure that the robot gripper has enough space to grip the meters from the side in the subsequent process. For this purpose, the adaptive gripper mechanism 2 of the present invention is used. When the adaptive gripper mechanism 2 removes the gas meter 4 from the container 1, the opening and closing drive cylinder 27 is in the retracted state and the single gripper components 26 are close together. When the meter is placed on the tooling tray after being removed, the telescopic end of the opening and closing drive cylinder 27 extends, and the distance between the single gripper components 26 is increased. Then the meter is placed on the tooling tray. When the telescopic end of the opening and closing drive cylinder 27 extends, it is transmitted through the first mounting plate 261 on the right and the connecting rod 24. The first mounting plate 261 slides on the lower end of the guide rail 25 and finally reaches the state of equal distance opening. Conversely, when the telescopic end of the opening and closing drive cylinder 27 retracts, the first mounting plate 261 will close.

[0071] The robot transfers the gas meter 4 to the upper end of the conveyor 3 and places it inside the corresponding tooling. Then, the gas meter 4 is transported to the next process for assembly or testing along with the corresponding tooling. The conveyor 3 is a commonly used conveying mechanism in the prior art, which can be driven by a conveyor belt or push rod. The input end of the motor or electric push rod used by the conveyor 3 is electrically connected to the output end of the main controller of the tooling fixture system. The main controller of the tooling fixture system controls the start and stop of the conveyor 3.

[0072] The domestic metrology verification institute only inspects meters that meet domestic standards. That is, the joint spacing of the inspected civilian gas meters is 130mm and the joint thread specification is M30×2. Gas meters 4 produced by domestic meter manufacturers are diaphragm gas meters and ultrasonic gas meters. The rotation volume of diaphragm civilian meters is different. The standard is 1.2L, there are 0.8L and 0.9L. The size of meters with different rotation volumes will vary, but all kinds of meters have a common feature, that is, the bottom is flat or can form a flat surface, the back is flat or a large-angle arc surface, and the bottom and back surfaces are generally at a 90° angle. Utilizing this common feature, the angle between the coplanar α of the inclined fixture 511 and the bottom support surface of the inclined fixture 511 is 90°.

[0073] The optimal effect is achieved when the angle between the coplanar α-fit and the lower surface of the inclined fixture 511 is 45°. This allows the gas meter 4 to be positioned by contacting the fixture with its bottom and back under gravity, ensuring that the center of gravity of all meters will not tip over on the tray. It also facilitates manual inspection of the front of the meter or operation on the front of the meter.

[0074] The back of different types of gas meters is mostly large-format. Therefore, a concave design is made in the middle of the back of the meter in the inclined tooling 511 support part. In this way, when the large arc back contacts the back of the tooling, theoretically, the two lines on both sides will contact each other, which is stable and does not shake.

[0075] After the gas meter 4 is placed in the inclined fixture 511, five of its six spatial degrees of freedom are already constrained. Only its position along the width of the tray remains undefined. There are two reasons for this: first, the left and right positions of the meter may exceed tolerances when placed by a robot or manually; second, the meter may move back and forth during transport due to stops, inertia, etc. Therefore, two limiting bosses 514 are designed on both sides of the fixture. During normal transport, the meter will not slide out of the two limiting bosses 514. At the same time, the gripper cylinder 265 designed to pick up the meter from the tray is wider than the inner dimensions of the adjacent two limiting bosses 514 when it opens. During the process of gripping the gas meter 4, the gripper cylinder 265 also determines the undefined sixth degree of freedom, thereby ensuring that the gas meter picked up by the robot from the inclined fixture 511 has a high degree of spatial consistency and meets the accuracy requirements of subsequent assembly / inspection processes.

[0076] On both sides of the inclined tooling 511, gripper openings 512 are designed to grip the inclined tooling 511, so that when the inclined tooling 511 is placed one after another on the conveyor 3, manual or robotic grippers can grip the inclined tooling 511. The tray blocker 6 can be a baffle, a baffle bar, or a device used to block various tooling. Its function is to block various tooling at the transfer position, so that the robotic gripper used for transfer can grip the tooling.

[0077] The 511 inclined fixture is recommended for use in the following situations: gas meter manufacturers, as it is compatible with various models of meters. It can be used in the assembly process, the testing process, on manual lines, on automatic lines, and in gas meter calibration institutes.

[0078] The advantages of the 511 inclined fixture are: the fixture has no moving mechanism, is low in cost and durable, and can self-position itself by combining the common structure of the table itself and the effect of gravity.

[0079] When using the inverted fixture assembly 52, the connector of the gas meter 4 is inserted between two connector limiting sleeves 522 located on the same fixture base plate 521. The upper end of the inner hole of the connector limiting sleeve 522 is designed with a chamfer to facilitate the insertion of the connector of the gas meter 4. The material of the connector limiting sleeve 522 is selected as nylon, bakelite and other plastics with good mechanical properties, which will not scratch the connector of the gas meter 4. The connector limiting sleeve 522 can be replaced after wear.

[0080] After the gas meter 4 is placed upside down through the connector into the connector limiting sleeve 522 of the hanging tooling assembly 53, all 6 degrees of freedom are determined. Therefore, the position of the meter that the robot picks up from the hanging tooling assembly 53 is the same, which makes it easier for the robot to put the meter on the testing table or place it on the tooling for assembly.

[0081] On both sides of the tooling base plate 521, holes 523 for gripping tooling pallets are designed to facilitate manual or robotic gripping of pallets when they are placed side by side on the conveyor line.

[0082] The recommended applications for the inverted tooling component 52 are: gas meter manufacturers that produce meters with the same connector spacing and specifications, where assembly and testing are basically automated processes, and domestic gas meter calibration institutes.

[0083] The advantages of the inverted tooling component 52 are: the tooling has no moving mechanism, it is low in cost and durable, the limit sleeve is easy to replace when worn, and it can self-position itself by combining the common structure of the table itself and the effect of gravity.

[0084] When using the hanging fixture assembly 53, the inner side of the meshing joint threaded pressure plate 533 has the same thread as the gas meter 4 connector. The two meshing joint threaded pressure plates 533 are installed symmetrically and closed by the elastic force of the spring 532. When closed, they do not form a complete circle, but are designed to clamp the connector. Positioning through holes are provided between the front and rear ends of the meshing joint threaded pressure plate 533. The external power mechanism can open the two meshing joint threaded pressure plates 533 located in the same pressure plate hole by inserting into the positioning through hole, that is, to allow the two meshing joint threaded pressure plates 533 to go from closed to open, so that the gas meter 4 connector can be fitted in.

[0085] Replace spring 532 periodically or when spring 532 malfunctions. Remove bottom cover 531 and directly remove engagement joint threaded pressure plate 533 from the bottom.

[0086] The tooling tray base plate 534 has a hole in the middle through which the gas meter 4 connector can pass. The tooling tray base plate 534 is fixed to the lower end of the bottom cover plate 531. There is a 1mm gap between the upper surface of the tooling tray base plate 534 and the vertically adjacent engagement connector threaded pressure plate 533, so that the engagement connector threaded pressure plate 533 can float up and down inside the pressure plate hole of the tooling tray base plate 534. Because the thread starting point of each gas meter 4 connector will be different, but the thread starting point on the engagement connector threaded pressure plate 533 is fixed, and the thread pitch is 2mm, half a turn is 1mm. Without this 1mm floating gap, the thread of the engagement connector threaded pressure plate 533 cannot guarantee that it will engage with the gas meter 4 connector thread every time.

[0087] After the gas meter 4 is fitted with the hanging fixture component 53, all 6 degrees of freedom are determined. In the subsequent production process, the hanging fixture component 53 and the gas meter 4 are integrated. The robot's gripping is directly on the hanging fixture, regardless of the meter's shape.

[0088] Notches for gripping the tooling pallet base plate 534 are designed on both sides of the tooling pallet base plate 534, so that when the tooling pallets are one after another on the conveyor line, the pallets can be gripped by manual or robotic grippers.

[0089] The hanging tooling component 53 is recommended for use in the following situations: gas meter manufacturers that produce meters with the same connector spacing and specifications, where all testing processes are automated; and domestic gas meter calibration institutes, where all testing processes are automated.

[0090] The advantages of the hanging fixture component 53 are as follows: After the gas meter 4 is mounted on the hanging fixture component 53, the gripping and positioning in each testing process are all performed on the hanging fixture component 53, regardless of the shape of the gas meter 4. The automated gripper design is simple and does not need to consider compatibility with gripping of various shapes. The positioning of the testing table does not need to be performed on the meter, but is also performed on the hanging fixture component 53, which is simple and reliable. Therefore, the hanging fixture component 53 is particularly suitable for automated meter testing by domestic testing institutes, because testing institutes may test meters from various meter manufacturers in China. The products of each meter manufacturer are constantly being iterated. Basically, the only thing that can be determined is the connector specifications and spacing.

[0091] During gas meter 4 testing, the two connectors are aligned with a set of test platform connectors 83 on the testing platform. The drive assembly 82 consists of a motor, reducer, synchronous belt, two synchronous pulleys, and its control system. The driven assembly 87 consists of a synchronous belt and two synchronous pulleys. The even-numbered test platform connectors 83 from left to right and the odd-numbered test platform connectors 83 from left to right are all connected as a whole by connecting rod 86. The upper surface of the second test platform connector 83 from left to right is fixedly connected to the upper end of the synchronous belt of the drive assembly 82, and the lower surface of the first test platform connector 83 from left to right is fixedly connected to the lower end of the synchronous belt of the drive assembly 82. The upper surface of the first test platform connector 83 from right to left is fixedly connected to the upper end of the synchronous belt of the driven assembly 87, and the lower surface of the second test platform connector 83 from right to left is fixedly connected to the lower end of the synchronous belt of the driven assembly 87. Every two test platform connectors from left to right... The test joints 83 form a group. The synchronous belt of the drive component 82, the synchronous belt of the driven component 87, and all the test joints 83 form a transmission system. When the output shaft of the motor of the drive component 82 rotates counterclockwise from the front view, the test joints 83 at the even-numbered positions from left to right slide to the left at the lower end of the guide rail 4 84. The upper end of the synchronous belt of the driven component 87 moves to the left synchronously, and the lower end of the synchronous belt of the driven component 87 moves to the right synchronously, causing the test joints 83 at the odd-numbered positions from left to right to slide to the right at the lower end of the guide rail 4 84. The two test joints 83 in the same group move closer to each other. When the output shaft of the motor of the drive component 82 rotates clockwise from the front view, the two test joints 83 in the same group move away from each other. This realizes that when gas meters 4 with different spacing joints are tested, the spacing of the test joints 83 can be automatically and accurately adjusted to be consistent with the spacing of the gas meter 4 joints.

[0092] The input terminal of the motor of the drive assembly 82 is electrically connected to the output terminal of its control system, and the input terminal of the control system of the drive assembly 82 is electrically connected to an external power supply. The control system can be a PLC controller or an industrial computer, etc.

[0093] The distance between the two test bench joints 83 in the same group can be determined by visual inspection and actual comparison with the gas meter 4 installed, or by using sensors such as grating rulers or distance sensors for detection. The detection data is fed back to the main controller of the tooling fixture system to achieve precise control of the displacement of the test bench joint 83.

[0094] When collecting front information from gas meter 4, the slide of linear guide rail 712 drives the transmission rod 713 and the Z-axis crossbeam 714 to move up and down as a whole. The Z-axis crossbeam 714 slides up and down between the two guide rails 715, thus limiting the Z-axis crossbeam 714. The front and rear displacement electric cylinder 72 drives the X-axis translation component 73 to move back and forth. Limiting post components can be set at the left and right ends of the front and rear displacement electric cylinder 72. The limiting posts move back and forth synchronously with the guide rail 732, thus providing radial protection for the front and rear displacement electric cylinder 72. The telescopic ends of the left and right displacement electric cylinders 731... The X-axis beam 733 and the slider three together slide to the right at the rear end of the guide rail three 732, realizing the overall rightward movement of the acquisition head mounting bracket 734. The telescopic end of the left and right displacement electric cylinder 731 retracts, realizing the overall leftward movement of the acquisition head mounting bracket 734. At the same time, the slider three and the guide rail three 732 limit the radial protection of the left and right displacement electric cylinder 731. The acquisition head mounting bracket 734 can be set in different quantities according to requirements. Visual cameras, near photoelectric acquisition heads and other signal acquisition devices required for gas meter detection can be installed on the bracket.

[0095] The movement of the three axes can be detected by adding sensors such as distance measuring sensors or grating rulers. The detection data is fed back to the main controller of the tooling fixture system to achieve closed-loop control.

[0096] In summary, the Z-axis can move the X and Y axes up and down as a whole, the Y-axis can move the X-axis forward and backward as a whole, and the X-axis can move the signal collector in front of each detection position left and right as a whole. This allows the signal collector to move along the Z, Y, and Z axes in front of each gas meter. This way, when switching between different meters for detection, there is no need to manually adjust the position of the signal collector.

[0097] Gas meters used in the market for civilian purposes 4 all have a common feature: their bottoms are either flat or can form a flat surface. Taking advantage of this common feature, the two corrugated suction cups 94 of the fixture plate 93 are raised above the upper surface of the fixture plate 93 when they are not in contact with the gas meter. Before placing the meter, a vacuum is opened in advance. When the gas meter 4 comes into contact with the corrugated suction cups 94, the corrugated suction cups 94 will retract, making the upper surface of the fixture plate 93 at the bottom of the gas meter 4 fit tightly together. At the same time, with two corrugated suction cups 94, the meter will not rotate on the fixture plate 93. All six degrees of freedom of this meter are fixed.

[0098] The working process of the lifting fixture mechanism 9 is as follows: the external vacuum generator is started, the vacuum adsorption is opened → the gas meter 4 is placed on the fixture plate 93 by the automated gripper, and the gripper leaves → the extension end of the second lifting cylinder 92 pushes out, the gas meter 4 rises with the fixture plate 93 until the gas meter 4's connector contacts and is tightly pressed against the test table connector 83, the vacuum is closed → the test table performs the test → after the test is completed, the vacuum is opened and the corrugated suction cup 94 sucks the meter again → the extension end of the second lifting cylinder 92 descends → the automated gripper grabs the gas meter 4 on the fixture plate 93 → the vacuum adsorption is closed → the automated gripper moves the meter away;

[0099] When detecting gas meters 4 at different heights, the second lifting cylinder 92 has a margin of error in its stroke. The cylinder stroke is compatible with the height difference of the meter. The second lifting cylinder 92 is a double-rod cylinder or a triple-rod cylinder, which has its own radial protection capability. The rising height of the tooling plate 93 can be controlled by a magnetic position switch fixed on the surface of the second lifting cylinder 92. The position detection of the rising height of the tooling plate 93 is achieved by detecting the piston position of the second lifting cylinder 92 through the magnetic position switch and feeding back to the main controller of the tooling fixture system.

[0100] Most residential gas meters require four AA batteries connected in series. During some testing procedures, the gas meter 4 needs power. When testing a gas meter with a 4x1 battery compartment, the elastic electrode plate 112, which is U-shaped, deforms inward at its lower end during insertion, facilitating the placement of the 4x1 fixture 111 into the battery compartment. After insertion, the external force is removed, and the elastic electrode plate 112 returns to its original shape under its own elasticity, thus securing itself in the battery compartment. This achieves the 4x1 fixture... The mounting base 111 is fixed in the battery compartment and connects the positive and negative contacts of the gas meter 4; one end of each of the two electrode leads 113 is connected to two elastic electrode plates 112, and the other end is connected to a 6V DC programmable switching power supply. Whether each lead is positive or negative can be controlled by the system; the 4-row 1-column tooling base 111 is made of insulating materials such as nylon. The 4-row 1-column tooling base 111 is wider at the top and narrower at the bottom, with a gap in the middle.

[0101] The 2-row, 2-column fixture 114 is also made of insulating materials such as nylon. The 2-row, 2-column fixture 114 is wider at the top and narrower at the bottom, with a gap in the middle. The second elastic electrode sheet 115 is made of a conductive elastic material. The second elastic electrode sheet 115 can be made by combining a styrene block copolymer substrate that provides elasticity with a graphene filler that provides conductivity; its shape is like the letter "Z". When installed in the gas meter 4 of the 2-row, 2-column battery compartment, the four second elastic electrode sheets 115 are fixed to the 2-row, 2-column fixture 114 with screws. The lower end of the 2-row, 2-column fixture 114 is narrow, and the lower end of the second elastic electrode sheet 115 is subjected to... When an inward force is applied, the fixture 114 can deform inward, making it easy to place the 2-row, 2-column fixture 114 into the battery compartment. After placement, the external force is removed, and the elastic electrode 115 recovers its deformation under its own elasticity, thus locking it in the battery compartment. This not only fixes the 2-row, 2-column fixture 114 in the battery compartment but also connects the positive and negative contacts of the gas meter 4. One end of the four electrode leads 116 is connected to the four elastic electrode 115 respectively, and the other end is connected to a 6V DC programmable switching power supply. The two leads on the left are connected to one circuit, and the two leads on the right are connected to the other circuit. Whether each lead is connected to the positive or negative terminal can be controlled by the system.

[0102] It is worth noting that the photoelectric sensor 267 disclosed in the above embodiments can be an HSE-R3B0D3N3R photoelectric switch, the front-to-back displacement electric cylinder 72 and the left-to-right displacement electric cylinder 731 can both be SFA50 servo electric cylinders, the linear guide rail 712 can be an ETH13 series servo linear module, and the motor and control system of the conveyor 3, robot, opening and closing drive cylinder 27, first lifting cylinder 262, gripper cylinder 265, drive assembly 82, and second lifting cylinder 92 can be freely configured according to the actual application scenario. The main controller of the tooling fixture system controls the operation of the photoelectric sensor 267, linear guide rail 712, conveyor 3, robot, front-to-back displacement electric cylinder 72 and left-to-right displacement electric cylinder 731 using methods commonly used in the prior art.
