Description

Technical Field

[0001] This invention belongs to the field of diaphragm gas meters, specifically relating to a diaphragm gas meter core clip assembly machine. Background Technology

[0002] A diaphragm gas meter is a volumetric metering instrument used to measure the amount of gas used. The working principle of a diaphragm gas meter is as follows:

[0003] The gas volume flow rate is measured by using two flexible diaphragm metering chambers. Under the action of pressure difference, the gas enters the two metering chambers of the mechanism alternately through the distribution valve. After being filled, it is discharged to the outlet. At the same time, it drives the flexible diaphragm in each metering chamber to reciprocate. The conversion mechanism converts this gas filling and exhaust cycle into the corresponding gas volume flow rate, and then transmits it to the counter through the transmission mechanism to complete the gas accumulation metering function.

[0004] Diaphragm gas meters are mainly composed of a casing (including an upper cover, a lower cover, and a sealing ring that presses the upper and lower covers together), a movement, and a counter. Among them, the movement itself has a relatively compact and complex structure, so it is usually assembled on a separate production line (for example, the "Automated Production Line for Diaphragm Gas Meter Movement" disclosed in application number 202111381250.0).

[0005] Before the diaphragm gas meter movement is installed into the housing, a clip needs to be inserted at the gas outlet. The clip not only serves to reliably support the movement by engaging with the housing, but also prevents incorrect installation when the movement is installed into the housing (avoiding incorrect installation of the gas inlet direction; the movement is divided into two types according to the gas inlet direction: forward (left inlet, right outlet) and reverse (right inlet, left outlet)).

[0006] Currently, clamps are generally assembled manually using a combination of manual labor and fixtures. However, manual assembly suffers from low efficiency, poor consistency, and worker fatigue, which is detrimental to ensuring the consistency and reliability of assembly quality.

[0007] Therefore, there is an urgent need to design a diaphragm gas meter movement clip assembly machine that can better ensure the assembly quality and consistency of the clips on the movement. Summary of the Invention

[0008] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a diaphragm gas meter movement clip assembly machine that can better ensure the assembly quality and assembly consistency of the clips assembled on the movement.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] A diaphragm gas meter movement clip assembly machine, characterized in that it includes:

[0011] The clip feeding mechanism is used for batch loading of clips and for continuously outputting clips one by one using electrical energy.

[0012] The clip gripping mechanism uses a controller to grip clips one by one and transfer the gripped clips to a predetermined position;

[0013] The clip alignment and assembly mechanism is used to control the alignment and insertion of individual clips with the clip mounting positions on individual diaphragm gas meter movements.

[0014] Compared with existing technologies, the advantages of the diaphragm gas meter core clip assembly machine in this solution are:

[0015] 1. Utilizing electrical energy for continuous feeding and assembly avoids the fatigue and poor assembly consistency issues that occur with manual assembly of clamps, thus helping to better ensure the quality of clamp assembly.

[0016] 2. By using a controller to control the assembly, it is possible to better realize digital and intelligent production and continuous operation, which can help improve the output and efficiency of movement assembly. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] In practical implementation: such as Figures 1 to 16 As shown;

[0043] A diaphragm gas meter movement clip assembly machine, including:

[0044] The clip feeding mechanism is used for batch loading of clips and for continuously outputting clips one by one using electrical energy.

[0045] The clip gripping mechanism uses a controller to grip clips one by one and transfer the gripped clips to a predetermined position;

[0046] The clip alignment and assembly mechanism is used to control the alignment and insertion of individual clips with the clip mounting positions on individual diaphragm gas meter movements.

[0047] The advantages of the diaphragm gas meter core clip assembly machine in this solution are:

[0048] 1. Utilizing electrical energy for continuous feeding and assembly avoids the fatigue and poor assembly consistency issues that occur with manual assembly of clamps, thus helping to better ensure the quality of clamp assembly.

[0049] 2. By using a controller to control the assembly, it is possible to better realize digital and intelligent production and continuous operation, which can help improve the output and efficiency of movement assembly.

[0050] The clip feeding mechanism is an automatic discharging vibratory feeder.

[0051] Vibratory feeders are a mature and widely used feeding device with good continuous feeding performance. They can also be configured with single-rail or multi-rail clinker guides for discharge according to actual needs, making them quite flexible in configuration.

[0052] The clamp gripping mechanism and the clamp alignment and assembly mechanism both employ a six-axis robotic arm, and the working hand of the six-axis robotic arm is equipped with a pneumatic clamping cylinder or a vacuum suction cup.

[0053] The six-axis robotic arm, also known as a "six-axis robot" (not shown in the figure), is a mature industrial product. It is controlled by a control system, has flexible movements, and high repeatability (displacement error within ±1mm).

[0054] The clamping mechanism includes an actuator and a controller;

[0055] The controller is used to store and execute preset instructions, and to drive and control the action actuator to complete the preset action according to the preset instructions;

[0056] The actuator includes a mounting bracket, a lifting cylinder, a lateral cylinder, and a clamp gripper; wherein, the lateral cylinder is fixedly mounted on the top of the mounting bracket, and the lateral cylinder is used to realize reciprocating lateral movement between the clamp gripping position and the pre-installation position before clamp assembly;

[0057] The lifting cylinder is vertically downward and is fixedly connected to the push rod of the horizontal moving cylinder.

[0058] The clamp gripper is fixedly mounted on the push rod of the lifting cylinder, and the clamp gripper is used to grip the clamp.

[0059] The advantages of the clamp-grabbing mechanism in this technical solution are:

[0060] 1. Lower cost, easier control of repeatability and achievement of high precision.

[0061] This technical solution employs a structural design consisting of a mounting bracket (within RMB 1000), a lifting cylinder (within RMB 1000), a lateral cylinder (within RMB 2000), and a clamping gripper (within RMB 500). (As is known to those skilled in the art, the cylinder must be used in conjunction with a pneumatic control valve (within RMB 500) and a controller (within RMB 500). This allows the hardware cost to be controlled within RMB 7000. Compared to using a six-axis robotic arm, this solution offers greater hardware savings.

[0062] At the same time, those skilled in the art will know that the cylinder is simpler to control, and the starting and ending positions of the cylinder push rod are easy to control precisely using limit blocks, thereby enabling high-precision reciprocating motion to be achieved continuously, and better ensuring that the clamp gripping and transfer operation can be reliable and durable.

[0063] 2. The overall size is more compact and occupies less space.

[0064] Compared to a six-axis robotic arm, the cylinder structure in the actuator of this technical solution is more compact, requiring less installation and operating space, and is easier to deploy and use in narrow spaces.

[0065] Example 1 of the clamp gripper (not shown in the figure): The clamp gripper is a pneumatic clamping cylinder or a vacuum suction cup.

[0066] If a pneumatic clamping cylinder is used, the pneumatic clamping cylinder is used to cooperate with the upper convex reinforcing block in the middle of the insertion direction on the clamp structure to achieve clamping;

[0067] If a vacuum suction cup is used, the vacuum suction cup is used to cooperate with the upper plane of the outer side of the clip structure in the insertion direction (with the side where the clip is assembled and connected to the movement as the inner side) to achieve suction.

[0068] Example 2 of the clamp gripper, such as Figures 5 to 7 As shown:

[0069] A clip gripper, characterized in that, from bottom to top, it comprises a plug-in part for tight fitting and a mounting part;

[0070] The overall structure of the tight-fitting plug-in part is a vertical flat plate. The bottom of the vertical flat plate structure of the tight-fitting plug-in part has a guide surface that is low in the middle and gradually rises towards the outer side in the width direction and is symmetrical from left to right. The end faces at both ends of the tight-fitting plug-in part in the width direction are vertical planes and form a pair of tight-fitting surfaces. The distance between the pair of tight-fitting surfaces matches the distance between the opposite sides of the pair of protruding pillars on the upper inner side of the clip. The tight-fitting plug-in part is inserted from top to bottom between the pair of protruding pillars on the upper inner side of the clip to form a tight-fitting connection.

[0071] The mounting part is used to fix it on the push rod of the lifting cylinder.

[0072] The advantages of the clamp gripper in this technical solution are:

[0073] 1. Simpler structure and lower cost

[0074] The gripping part of the clamping hand is a tight-fitting plug-in part. The overall structure of the tight-fitting plug-in part is a vertical and flat plate structure. There are no additional complex actuation mechanisms, the structure is very simple, the cost is lower, and it can better achieve cost reduction and efficiency improvement.

[0075] 2. The gripping process adaptively adjusts the posture, better ensuring the correctness and consistency of the gripping hand's posture after being grasped by the clamp, resulting in better gripping performance.

[0076] When gripping, simply move from top to bottom directly above the clamp. Once the bottom guide surface of the tight-fitting connector contacts the clamp, the clamp at the end of the vibratory feeder's discharge guide rail will gradually adjust its posture along with the guide surface. This will allow the pair of tight-fitting surfaces of the tight-fitting connector to fit tightly into the opposite sides of the pair of protruding pillars on the upper inner side of the clamp, thus gripping the clamp and ensuring the correctness and consistency of the clamp's posture. This lays a good foundation for the precise insertion of the clamp in the future.

[0077] The guide surface is a circular arc surface.

[0078] In practice, it is preferable that the curvature of the guide surface is consistent with the curvature of the inner bottom surface of the clip (the curvature is 21).

[0079] Compared to the inclined guide surface, the arc surface has no sharp point at the bottom, which provides better protection. In addition, the angle between the arc surface and the tight-fitting surface is smaller, which makes the arc surface more continuous for adjusting the clamp's posture and better ensures the smooth transition and continuity of the clamp from posture adjustment to final contact and connection with the tight-fitting surface.

[0080] The vertical plate-shaped structure of the tight-fitting insertion part is perpendicular to the direction of movement of the clip alignment insertion. The vertical plate-shaped structure of the tight-fitting insertion part has a front plate and a rear plate in the forward and backward direction of movement along the clip alignment insertion.

[0081] The mounting part is a rectangular column structure that protrudes upward from the top surface of the tight-fitting plug-in part; the rectangular column structure has an overlapping area on its vertical rear side surface that coincides with the vertical flat plate structure of the tight-fitting plug-in part in the vertical direction and on the rear side plate surface.

[0082] The top surface of the rectangular column structure, located outside the overlapping area, is provided with a vertically penetrating rectangular hole for assembly. The front surface of the rectangular column structure, in the forward and backward direction of the clamp alignment and insertion movement, is also provided with a locking hole that communicates with the rectangular hole for assembly.

[0083] The mounting part of the above-mentioned clamp gripper has the advantage of high structural strength. It can be precisely installed by fitting the rectangular hole for assembly with the matching insertion mounting block, and finally by the screw installed in the locking hole to achieve precise and reliable installation.

[0084] In addition, the above-mentioned clamp gripper is a one-piece molded structure, which is relatively regular and easy to process and shape.

[0085] The clamp gripper mounting structure includes an insertion mounting block and a rear abutment block that are fixedly mounted on the downward-facing push plate of the lifting cylinder;

[0086] The insertion mounting block is used to fill the rectangular hole for assembly, and the insertion mounting block has threaded holes that correspond one-to-one with the locking holes and is fixedly connected by screws;

[0087] The upper section of the rear abutment block is connected to the rear side of the mounting part, the lower section of the rear abutment block extends downward and contacts the rear side plate of the vertical plate structure of the tight-fitting insertion part, and the lower end of the rear abutment block is located within the rear side plate of the vertical plate structure of the tight-fitting insertion part.

[0088] The above-described clamp gripper mounting structure can securely and accurately assemble the clamp by inserting the mounting block; the rear abutment block can form a close-fitting support for the vertical plate structure of the clamping insertion part from back to front in the forward and backward direction of the clamp alignment and insertion movement, preventing the vertical plate structure of the clamping insertion part from deforming under the pushing force of the push block of the clamp alignment and assembly mechanism, and ensuring the reliability of the vertical plate structure of the clamping insertion part for a long time.

[0089] The clamp alignment assembly mechanism includes a mounting plate, an alignment guide groove, a push block, and a push cylinder;

[0090] The alignment guide groove is horizontal in shape and fixedly installed on the mounting plate. The left side wall, right side wall and bottom wall of the alignment guide groove all have grooves and together form an inverted "U" shaped guide positioning groove. The grooves on the left side wall and right side wall are slidably connected to the corresponding surfaces of the protrusions on both sides of the width direction of the clip and form an alignment guide for the clip.

[0091] The alignment guide groove has a pre-installation position for inserting the clip. The top of the grooves on the left and right sides of the alignment guide groove at the pre-installation position has an entry notch for the clip to protrude from both sides in the width direction. The end of the alignment guide groove away from the pre-installation position is an open end and forms an assembly end for alignment and pressing with the clip mounting position on the movement.

[0092] The push cylinder is fixedly installed on the end of the alignment guide groove that is opposite to the assembly end and the insertion end along the length direction of the alignment guide groove, and the push cylinder is arranged along the length direction of the alignment guide groove with the push rod facing the pre-insertion position.

[0093] The push block is fixedly mounted on the push rod and has a push head that extends into the alignment guide groove. The push head is used to push the clip that has been inserted through the pre-installation position.

[0094] The advantages of the clamp alignment and assembly mechanism in this solution are:

[0095] 1. To enable its use in conjunction with the clamp gripper of the vertical and horizontal plate structure during assembly and use:

[0096] First, the clamp gripper with its vertical and horizontal plate structure can grip the clamp to the ready-to-install position through a tight fit with the clamp;

[0097] Secondly, after the clamp gripper grabs the clamp into the pre-installation position, the push cylinder is activated. When the push block pushes against the clamp, it is positioned by the limiting action of the inverted "U"-shaped guide positioning groove. The clamp gripper can then be lifted out to perform the next gripping operation.

[0098] As can be seen from the above, this technical solution can be used smoothly in conjunction with the clamp gripper of the vertical and horizontal plate structure.

[0099] 2. Good guidance and alignment effect

[0100] Once the clip has been inserted into its pre-installed position, it can achieve precise positioning and alignment by sliding and engaging with the inverted "U"-shaped guide positioning groove, thereby effectively ensuring the accurate pressing of the clip onto the movement.

[0101] The overall structure of the push block is an L-shaped block structure. The vertical side of the L-shaped block structure is used for fixed connection with the push rod, and the horizontal side of the L-shaped block structure forms the push top.

[0102] The push block has an overall L-shaped block structure, which has the advantage of high structural strength; and the L-shaped structure is also relatively convenient to install.

[0103] The push-top has a laterally extended push-top and a downwardly protruding push-top. The laterally extended outer end face of the downwardly protruding push-top is used as the outer end face of the push-top clip, and the laterally extended push-top is used as the outer end face of the upwardly protruding reinforcing block in the middle of the insertion direction on the push-top clip structure.

[0104] The above description of the outer and inner sides is based on the outer and inner sides of the clips mounted on the movement.

[0105] With the push-top structure described above, not only can the horizontally extended push-top be used to form a vertical limit, making it easy for the clamp gripper to move upward and release the material smoothly; it can also push the two sides of the clamp simultaneously through the horizontally extended push-top and the downward convex push-top, making the push force distribution more uniform and the force more reasonable, thus better ensuring the pushing and pressing assembly quality of the clamp on the mechanism.

[0106] The clamp is aligned with the assembly mechanism, and the mechanism also includes a core facing the assembly mechanism; the core facing the assembly mechanism includes a conveyor belt, a movement-to-position detection sensor, and a lifting cylinder;

[0107] The conveyor belt consists of two conveyor belts arranged side by side with a gap between them; the conveyor belts are provided with clamp pressing positions along their length; and the lifting cylinder is fixedly installed at the clamp pressing positions along the length of the gap between the two conveyor belts.

[0108] The push rod of the lifting cylinder faces upward and is fixedly installed with a core tooling. The core tooling is lower than the conveying support surface of the conveyor belt at the push rod retraction stop point, and can push the lower side of the core loaded on the core tooling to disengage from the conveyor belt after the push rod is pushed out.

[0109] The movement positioning detection sensor is used to send a trigger signal to the controller when the mechanism on the conveyor belt moves to the clamp pressing position, so that the controller controls the conveyor belt to stop and drives the push rod of the lifting cylinder to rise and complete the pre-assembly positioning.

[0110] The operating principle of the movement facing the assembly mechanism in this design is as follows:

[0111] First, the mechanism to be assembled is continuously fed in via a conveyor belt;

[0112] Next, when the mechanism reaches the clamping position on the conveyor belt, the movement detection sensor detects that the mechanism sends a trigger signal, the controller controls the conveyor belt to stop and drives the lifting cylinder to lift the push rod of the lifting cylinder and complete the pre-assembly positioning.

[0113] The advantage of having the movement directly aligned with the assembly mechanism in this design is:

[0114] When the movement reaches the clamping position on the conveyor belt, it lifts the movement and its fixture off the conveyor belt and into the assembly position. This mechanism has few control components, automatically detects the movement's position signal using sensors, and boasts high repeatability, ensuring consistently accurate positioning of the movement during clamping.

[0115] The movement to position detection sensor is a distance sensor, and the distance sensor's measuring head is directly facing the assembly end of the alignment guide rail groove.

[0116] The advantages of using the above distance sensors are:

[0117] When an object or a directly opposite part of an object appears in the distance sensor's ranging head, precise distance measurement can be achieved. This allows for accurate determination of whether the movement has reached the latching position, thus ensuring more precise positioning of the movement.

[0118] In practice, the distance sensor is preferably a laser distance sensor with stronger anti-interference capabilities (such as the LR-X series small laser sensor manufactured by Keyence).

[0119] Enclosures are fixedly installed on the left and right outer sides along the length of the two conveyor belts. The enclosures are used to slide and engage with the end sides of the core conveyed on the two conveyor belts.

[0120] In practice, it is preferable to use guardrails as the fencing. Guardrails have a simpler structure and are easier to deploy.

[0121] By using the above-mentioned barriers, the movement of the machine parts conveyed on the conveyor belt can be limited, which can not only effectively prevent the machine parts from falling off the conveyor belt, but also better ensure the conveying posture of the machine parts, and better ensure that the machine parts reach the clamp pressing position in an accurate posture.

[0122] The movement is facing the assembly mechanism and also includes a push positioning structure. The push positioning structure includes a push cylinder, which is fixedly installed by a bracket. A push plate is fixedly installed on the outside of the push rod of the push cylinder.

[0123] The push plate is used to push the end side of the movement on the movement tooling on the movement tooling that has been lifted to the highest point by the lifting cylinder, so that the clip mounting position of the movement can be tightly abutted against the position of the end output clip aligned with the guide rail groove.

[0124] The above-mentioned push-positioning structure can use a push rod cylinder to apply lateral pressure to the movement. This lateral pressure can overcome the pressure that gets stuck during the press-fitting process, ensuring the stability and reliability of the press-fitting assembly process and ensuring assembly quality.

[0125] The above are merely preferred embodiments of the present invention. It should be noted that any modifications and improvements made by those skilled in the art without departing from the present technical solution should also be considered to fall within the scope of protection claimed in this claim.
