Description

Seal ring feeding mechanism

Technical Field

The invention belongs to the field of film type gas meter assembly lines, and particularly relates to a seal ring feeding mechanism in a film type gas meter assembly line.

Background

The diaphragm gas meter is a volumetric metering device for metering the usage of gas. The working principle of the diaphragm gas meter is as follows:

the gas volume flow is measured by adopting two flexible diaphragm measuring chambers, under the action of pressure difference, fuel gas alternately enters the two measuring chambers of the movement through the distributing valve, is fully filled and discharged to the gas outlet, meanwhile, the flexible diaphragms in each measuring chamber are pushed to do reciprocating motion, the circulation process of the inflation and the exhaust is converted into corresponding gas volume flow through the conversion mechanism, and then the corresponding gas volume flow is transmitted to the counter through the transmission mechanism, so that the fuel gas accumulation and measurement function is completed.

The membrane type gas meter mainly comprises a shell (comprising an upper cover, a lower cover and a sealing ring for pressing the upper cover and the lower cover), a movement, a counter and other parts. Among them, the movement itself is relatively compact and complex in structure, so that it is generally assembled by a separate production line (for example, application No. 202111381250.0, published as "film gas meter movement automation line").

Film gas meter assembly refers to the assembly of an assembled movement (also referred to as a "movement assembly") into an upper and lower cover and the press sealing achieved by a seal between the upper and lower covers.

Currently, the prior art discloses membrane gas meter assembly lines, for example, in the prior literature, "design and implementation of gas meter assembly lines" (Xu Peng et al, "design and implementation of gas meter assembly lines" mechanical engineering and automation 6 (2017): 3. "mechanical engineering and automation", 2017, 12 months: 185-186 pages).

The sealing ring in the membrane type gas meter is large in size (in terms of external magnetic steel) due to the fact that the structure is relatively large in size, and continuous feeding is difficult to achieve by adopting a vibrating disc; therefore, how to effectively discharge and feed the sealing ring is a technical difficulty which the industry has not solved.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to solve the technical problems that: how to provide a seal ring feeding mechanism capable of effectively discharging and feeding the seal ring.

In order to solve the technical problems, the invention adopts the following technical scheme:

the seal ring feeding mechanism is characterized by comprising a cantilever, a cantilever supporting structure and an upper wire seal ring in-place detection module;

the rear end of the cantilever is fixedly arranged on the cantilever supporting structure; the front section of the cantilever is provided with a hanging seal ring conveying belt assembly, a plurality of seal rings can be sleeved on a conveying belt of the seal ring conveying belt assembly in parallel, and the seal rings can be output one by one to the front end direction of the conveying belt under the drive of a synchronous belt driving motor;

the upper coil seal ring in-place detection module is used for detecting whether a seal ring exists at a front end to-be-extracted position of the conveying belt or not and outputting a detection signal.

The theory of operation of this scheme seal feeding mechanism is:

the upper coil seal ring in-place detection module is used: when the position of the sealing ring conveying belt to be taken is detected to be provided with the sealing ring, the driving motor of the synchronous belt is stopped, and the sealing ring at the position is in the following state: can be clamped and transferred by the seal ring transferring structure;

when the in-place detection module of the upper coil sealing ring does not detect the sealing ring in less than the preset time, the synchronous belt driving motor drives the conveying belt to continuously convey forwards and supplement materials to the front end to-be-taken material position;

When the coil feeding in-place detection module does not detect the coil at a time which is more than or equal to the preset time, a material shortage signal is output to remind workers of timely material supplementing.

Compared with the prior art, the seal ring feeding mechanism of this scheme has the advantage that:

the conveyer belt of the sealing ring conveyer belt assembly on the cantilever can hang and store a plurality of sealing rings through the length of the conveyer belt, and can send out the sealing rings one by one to the front end to-be-taken material position. Therefore, the scheme can realize batch discharging and feeding of the sealing rings, and well solves the problem of difficulty existing in the industry.

Detailed Description

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

The specific implementation method comprises the following steps: as shown in figures 1 to 3 of the drawings,

I. film type gas meter assembly process

The film type gas meter assembly process comprises the following steps:

firstly, setting an assembly quality detection sensor at least one assembly position on a membrane gas meter assembly production line, wherein the assembly quality detection sensor is used for detecting whether an NG state occurs at the assembly position; in addition, NG article placing positions are arranged near the offline position of the film type gas meter assembly production line;

secondly, when the assembly quality detection sensor detects the NG state, the assembly part on the loading seat of the assembly station is marked as an NG article, and the assembly station is started to the offline position: the guide rail conveying mechanism of the film type gas meter surface assembly production line keeps normal conveying beats to convey the loading seat carrying the NG, and the loading seat carrying the NG is not assembled by the subsequent stations any more to be finished parts;

finally, when the loading seat carrying the NG is conveyed to the offline station: and transferring the NG to the NG placing position by using a mechanical arm when the film type gas meter goes off the production line.

Compared with the prior art, the film type gas meter assembly process in the scheme has the advantages that:

1. Even when the NG state is detected by any assembly quality detection sensor, the guide rail conveying mechanism of the whole film type gas meter assembly production line can not stop, and still keeps the normal conveying beat, so that the whole film type gas meter assembly production line can not stop, and the production efficiency can be effectively ensured.

2. The NG is not assembled by the subsequent stations from the assembly station when the NG state is detected to the offline position, so that the NG is in the initial NG state, the subsequent workers can conveniently check the manual state of the NG in the NG position, and the parts which can be online are online again for the assembly of the gas meter; therefore, the production beat of the film type gas meter assembly production line is not affected, and meanwhile, the subsequent processing of the NG can be conveniently carried out.

The NG article placement position comprises a NG article placement bracket;

the NG article placing bracket is integrally arranged independently of a film type gas meter assembly production line;

the NG article placing bracket is arranged on the ground outside the offline position of the guide rail conveying mechanism of the film type gas meter assembly production line;

the NG article placing support is provided with a placing plane for placing a plurality of NG articles.

The NG article placing bracket is arranged in a structure independent of a film type gas meter assembly production line; therefore, the method can flexibly expand and reform the cloth of the existing film type gas meter assembly production line, and has more practicability.

The NG article placing support comprises a supporting frame, a driving wheel, a driven wheel and a conveying belt, wherein the driving wheel and the driven wheel are arranged at the top of the supporting frame; the driving wheel is driven by a driving motor, and the driving motor is electrically connected with a motor controller.

The advantage of adopting above structure is: the coordinate of the XYZ axis of the initial position of the upper surface movement of the conveyor belt can be used as the placement coordinate of the NG article placed on the conveyor belt by the offline manipulator, so that the control of the placement action of the offline manipulator is facilitated to be simplified, and the reliability of the offline manipulator for placing the NG article is improved.

Meanwhile, due to the NG article placing support with the structure, after the NG article is placed by the offline manipulator, the conveyor belt acts and the unique placing coordinates are vacated again to allow the offline manipulator to place the NG article again.

In practice, the drive control for the drive belt can be preferably achieved in two ways:

1. The motor controller is connected with a control system signal of a film type gas meter assembly production line:

thus, the action of the transmission belt can be controlled through time sequence: the NG is firstly placed on the placement coordinates on the conveyor belt by the mechanical arm after the feeding is performed according to the time sequence, and then the motor controller controls the action of the conveyor belt.

2. The motor controller is not connected with a control system of the film type gas meter assembly production line:

in this way, a detection sensor can be arranged on the NG article placement bracket to detect whether the placement coordinates on the conveying belt are empty, if not, the detection sensor is delayed for a plurality of seconds to act after obtaining the detection signal (the plurality of seconds is shorter than the time required by a single beat of the film type gas meter assembly production line).

The assembly station for setting the assembly quality detection sensor is as follows: one or more of an upper cover feeding station, an outer magnetic steel assembling station, an upper cover gluing station, a core assembling station, a sealing ring assembling station and a lower cover assembling station.

Above set up the assembly quality detection sensor at single assembly station or a plurality of assembly stations, can detect the assembly quality of each station to can guarantee the assembly quality of diaphragm type gas table assembly line better.

The assembly quality detection sensor is a photoelectric sensor, the photoelectric sensor is arranged at a station to be detected, and a detection head of the photoelectric sensor faces to an assembly part to be detected on the assembly station.

After the photoelectric sensor is arranged at the corresponding assembly station, the photoelectric sensor can obtain two corresponding different detection signals when the corresponding assembly part is installed or not installed, so that whether the assembly part is installed or not can be judged through the two different detection signals, and whether the NG state occurs or not can be judged according to the judgment.

In implementation, the photoelectric sensor is preferably a laser photoelectric sensor or an optical fiber sensor with stronger anti-interference performance. In this way, a more reliable assembly quality detection signal can be permanently obtained.
