Description

Technical Field

[0001] The present invention relates to the technical field of pressure gauge verification, and specifically to an automatic sorting and verification device and system for pressure gauges. Background Art

[0002] A pressure gauge refers to an instrument that uses an elastic element as a sensitive element to measure and indicate a pressure higher or lower than the ambient pressure. It is mainly used for safety protection: 1. Measurement of the main steam drum and feed water pressure of power station boilers; 2. Measurement of the pressure in the air receiver and main pipe of fixed air compressors; 3. Measurement of the oil pressure of generators and steam turbines and the pressure of locomotives; 4. Measurement of pressure with an alarm device; 5. Measurement of the pressure in a sealed pressurized container; 6. Measurement of the pressure of harmful, toxic, and severely corrosive media, etc. It is extremely widely used, almost covering all industrial processes and scientific research fields. Especially in the industrial process control and technical measurement processes, due to the high mechanical strength and convenient production of the elastic sensitive element of the mechanical pressure gauge, the mechanical pressure gauge has been more and more widely used.

[0003] Among them, the "pressure gauge verification system and its detection method" disclosed in the Chinese patent with the application number "CN202311410394.3" is also an increasingly mature technology, which records that "the present invention discloses a pressure gauge verification system and its detection method, which effectively combines the verification operation system with mechanical testing through a camera component to realize directly printing and outputting a two-dimensional code certificate from pressure gauge verification, improving the convenience of operation; a pressure gauge verification system includes a computer control terminal, a pressure gauge verification table, a camera component, and a printer; the computer control terminal is communicatively connected to the camera component and the printer, the computer control terminal is provided with a verification operation system, and the verification operation system includes a business management interface and a system management interface, wherein the business management interface includes a real-time verification interface and a verification record interface; the pressure gauge verification table includes a pressure inlet device, an output port, and a pressure regulating device, the pressure inlet device provides the medium required for pressure calibration, the output port 2 is used to install the pressure gauge to be tested, and the output port 2 is used to install the standard device; In addition, it also has the following disadvantages: 1) When traditional pressure gauges are automatically verified, they cannot automatically perform batch verification and transmission of the gauge bodies, and cannot achieve unified filing after the batch release of the gauge bodies. Moreover, during the process of automatically verifying the gauge bodies of pressure gauges, the same pressure gauge standard device cannot be used to verify various models of pressure gauges, and automatic sorting cannot be achieved to screen out a batch of qualified and unqualified products.

[0004] 2) In addition, the writing of certificates is also of paramount importance. Traditional pressure gauge inspection devices cannot grant certificates to qualified and unqualified pressure gauges based on the gauge bodies inspected by the machine. Instead, manual calculation is required to write the unqualified gap threshold, and then the certificate can be manually granted. This makes it difficult and inconvenient to grant certificates for pressure gauges. At the system level, this type of pressure gauge inspection scheme usually cannot be combined with the system to jointly realize the inspection of pressure gauges and grant corresponding certificates.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1) By adopting a rotating disk and an air inflation seat for gas inflation, combined with the elastic buffer state of a buffer spring to control the contraction seat to achieve tightening, and fixing the pressure gauge body to the clamping of the pressure gauge on the contraction seat. The positions on the inflating valve and the pipe body connecting the air pipe are matched, and the stepping motor changes the rotation of the rotating disk surface to ensure the fastening and limiting of each pressure gauge. It solves the problem that the installation of pressure gauges with different calibers is limited; 2) By adopting a pneumatic cylinder and the rotation of the upper feeding disk surface, it gradually realizes the batch discharging of the U-shaped dialing frame. After the upper feeding motor is powered on, the rotation of the upper feeding disk surface is completed. Through the tightening of the elastic torsion spring and the connecting base, the pressure gauge is automatically wrapped and fixed, which is convenient for discharging and matching the pressure gauge to be placed into the pressure gauge verification mechanism. Automatic feeding, automatic sorting and discharging save time and manpower and improve the verification efficiency; 3) By adopting the verification cabinet to automatically classify and label the pressure gauges, according to the qualified characteristics of the pressure gauges, the computer automatically awards the verification records and verification certificates for printing. The qualified products are labeled with green two-dimensional codes, and the unqualified products are labeled with red two-dimensional codes. It is easy for people to distinguish between qualified products and unqualified products, and the corresponding verification certificate information can also be queried by scanning the two-dimensional code. It solves the problem of manually reading the verification data and then calculating the error and manually issuing the verification certificate.

[0017] 4) By adopting a pressure gauge downward sliding channel to convey it onto a conveying track, the classification transmission improves the conveying efficiency. By adopting the conveying track and the arc-shaped bearing pieces for classification, the pressure gauges are gradually unified archived. The classification and unified archiving of qualified products and unqualified products have better limitations for the archiving and screening of pressure gauges; 5) Adopt the system authorization solution. When calibrating the pressure gauges that have been authorized as qualified products, promptly issue the qualified certificates for the pressure gauges. The certificates use the two-dimensional codes carried by the server to write information, recording the qualified air pressure calibration data of the pressure gauges. In addition, the certificates granted by the two-dimensional codes can be changed to the desired styles according to subsequent calibration standards, and various information of the pressure gauge certificates can be edited. In addition, each system controls and respectively achieves the mutual structure with the hardware. The labeling solution uses the labels with writeable two-dimensional code information possessed by the labeling machine itself, plus direct downward pressure to directly complete the automatic pressure labeling of the labels on the production line, eliminating the irreversible situation of traditional laser labeling. 6) Through the adoption of the pressure gauge calibration institution, the rotating mechanism and the system, the three cooperate with each other in terms of hardware and software. The pressure gauge calibration institution can automatically calibrate the qualified or unqualified products of various models of pressure gauges. The rotating mechanism can batch-automatically calibrate the pressure gauges. The number of pressure gauges on the conveying and calibrating production line can be freely added as needed, and can automatically feed materials, separate inspections, and sort and unload materials; the calibration system can automatically generate two-dimensional codes, calibration records and calibration certificates and print them, realizing the full-automatic calibration of pressure gauges.

[0038] Step 1: Verify the pressure gauge. Automate the pressure gauges to be verified (the overhead suspension chain conveyor line of the orbital conveyor ensures automated loading), and uniformly stack and bundle them on the surface of each U-shaped toggling frame 35. Through the surface of the specific U-shaped toggling frame 35, bundling is achieved. After positioning, it is ensured that the pressure gauge body can be better grasped. The triggering of the grasping action is based on the telescopic movement of the cylinder body of the pneumatic cylinder 33. The corresponding loading motor 37 is powered on to drive the rotation on the disk surface of the loading tray 34. Through the disk surface structure of the specific loading tray 34, rotation is achieved, promoting batch automated loading during the verification of the pressure gauge. As the corresponding structure of the pressure gauge approaches the disk surface of the rotating disk 11 for correspondence, the stepping motor 21 is powered on to drive the rotating mechanism 2 of the rotating disk 11 to rotate. At this time, it is combined with the induction structure of the automatic loading mechanism 3. When the top of the vertically corresponding retraction seat 14 is connected, the corresponding U-shaped toggling frame 35 needs to be released. By starting the telescopic movement of the cylinder body structure of the pneumatic cylinder 33, after triggering, one end of the bottom U-shaped toggling frame 35 is driven to be lifted. At this time, the telescopic state of the cylinder body structure of the pneumatic cylinder 33 changes to release the surface of the U-shaped toggling frame 35. After release, it is directly connected to the top of the inflation seat 12. According to the elastic telescopic movement of the buffer spring 13, it further triggers the tightening of one end of the specific retraction seat 14, ensuring that the pressure gauge induction seat 15 enters the tightening and clamping stage, and the bottom of the pressure gauge conduit 16 is connected through the connection of one end of the detection base 17. Step 2: Inflate the gas. At this time, the user turns on the pump body structure of the air pump 42 to achieve power-on. One end of the specific guiding air pipe 41 is connected by the user, and then one end of the guiding air pipe 41 is connected. After the gas is transferred and separated at one end of the pipe-connected air pipe 193, it is introduced into the code dial 18. According to the information of the pointer of the air pressure verification gauge body and the timing pressure difference, based on the analysis of the buffer spring 13 and the contraction seat 14, the bottom of the placed pressure gauge is grasped and sealed and fixed, and gas is injected to calculate the data difference (the qualified pressure difference calculated by the computer 102 itself and the pressure difference sensed by the actual receiving pointer); This information is obtained by simple system operations of addition and subtraction to obtain the difference data (both qualified and unqualified products are calculated uniformly and presented on the computer 102, which is the basis for generating two-dimensional codes or numbered certificates). The two-dimensional code certificates generated from these data information are set with corresponding automatic certificates according to the operation keyboard 103. With different changes in air pressure, matching is achieved. The situation of the qualified products on one side of the verified label is automatically transferred to the position of the qualified product conveying mechanism 7; The adjustment block controlled by the PLC realizes forward and backward displacement. According to the tightening of the surface edge of the gripper 86, the folding change of the gripper 86 is controlled, and the gauge body is held and taken out (the contraction seat 14 is automatically loosened). After taking out, it is placed on the surface of the transmission track 711 and finally extended and conveyed; For automatic two-dimensional code labeling, the qualified product two-dimensional code labeling machine 87 is used to engrave the certificate two-dimensional code on the surface of the gauge body in the form of labeling by the labeling machine. The ccd camera corresponds to the searchlight (repeated operations for batch transportation of qualified pressure gauges). The qualified pressure gauges are transferred to the conveying conduit 57 and guided to slide onto the surface of the insertion slot 58 and are gradually shunted and conveyed down by the transmission roller 65 and the baffle 66; Unqualified products: Similarly, unqualified products will be screened into the area of the defective product selection mechanism 9. The electric push rod 92 is started to control the rod body of the second telescopic strut 93 to extend and move. The defective product two-dimensional code labeling machine 94 is used to label the unqualified products. The operator ejects them according to the second U-shaped bracket 95. When the rotating disk 11 rotates, until it slides down to the buffer piece 96 and directly slides onto the surface of the pressure gauge sliding channel 97 until it moves onto the surface of the conveying track 99 and moves back and forth. After moving at one end of the arc-shaped bearing piece 991, it directly moves to one end of the arc-shaped bearing piece 991 to achieve forward and backward movement. One end of the arc-shaped bearing piece 991 moves back and forth, and finally it is stored; Embodiment 2: Please refer to the attached instructions Figures 18 - 19 The distinguishing features of this solution compared with Embodiment 1 are: It is equipped with a verification system 20: This verification system 20 includes: an authorized certificate writing module 211, an unqualified certificate writing module 22, a laser printing module 23, a certificate information editing module 24, and a pressure gauge pressure measurement verification module 25; Among them, the pressure measurement and verification module 25 of the pressure gauge also covers: a qualified range data setting module 251, a non-qualified range data setting module 252, and a pressure difference data writing module 253; The pressure measurement and verification module 25 of the pressure gauge is composed of a pressure detector.
