Description

Technical Field

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules.

[0003] Pressure sensors are usually composed of pressure sensitive elements, devices that convert the force or motion generated by the pressure sensitive elements into electrical parameters, and devices that display or record the electrical parameters. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. They are widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemicals, oil wells, electric power, ships, machine tools, pipelines and many other industries.

[0004] In order to ensure reliable sealing under various working conditions and prevent media leakage while maintaining cost-effectiveness and easy maintenance, O-rings are commonly installed in pressure sensors.

[0005] At the same time, in order to form an effective seal between the screw and the housing to prevent liquid or gas leakage, an O-ring will be put on the screw first, and then the screw will be riveted to the housing. When the screw is riveted to the housing, the O-ring is compressed, generating sufficient sealing force to prevent medium leakage.

The workpiece enters the small turntable component 2 from the feeding component 3, and is sequentially subjected to laser coding, resistance testing, a first test, a second test, a third test, O-ring loading, a fourth test and a fifth test on the small turntable component 2. Subsequently, the workpiece is unloaded onto the flip component 9, and the flip component 9 flips the workpiece to the back side, and at the same time, the workpiece is fed into the large turntable component 4. The workpiece is sequentially subjected to a sixth test, a seventh test, an eighth test, a ninth test, screw and O-ring loading, a tenth test, an eleventh test, a twelfth test, a thirteenth test, a fourteenth test, a fifteenth test and a sixteenth test. Finally, the workpiece is unloaded by the blanking component 5, and at the same time, the manipulator 10 moves the workpiece to the stacking component 6 for stacking.

[0077] Please focus on Figure 3 , wherein the small turntable assembly 2 includes a small indexing plate 208, on which laser coding and resistance value testing stations 201, a first detection station 202, a second detection station 203, a third detection station 204, an O-ring loading station 205, a fourth detection station 206, a fifth detection station 210 and a material unloading station 207 are evenly distributed, and each station is equipped with a tool 209, corresponding to the laser coding and resistance value testing station 201 and the laser coding and resistance value testing assembly installed on the workbench 1, corresponding to the first detection station The camera component one corresponds to the second inspection station 202 and is installed on the workbench 1, the camera component two corresponds to the second inspection station 203 and is installed on the workbench 1, the third inspection component corresponds to the third inspection station 204 and is installed on the workbench 1, the O-ring loading component corresponds to the O-ring loading station 205 and is installed on the workbench 1, the camera component three corresponds to the fourth inspection station 206 and is installed on the workbench 1, the camera component four corresponds to the fifth inspection station 210 and is installed on the workbench 1, and the flip component 9 corresponds to the position of the unloading station 207.

[0078] The workpiece is fed into the laser coding and resistance testing assembly through the feeding assembly 3 for laser coding and resistance testing. The workpiece is then sent to the first inspection station 202, where the camera assembly 1 is used to photograph the positive end surface of the workpiece to detect whether there are traces and dents. Please refer to Figure 2, then the workpiece is sent to the second inspection station 203, and the blue rivets 11 on the workpiece are inspected by camera component 2. For qualified workpieces, there are four blue rivets 11, and they are located at the four corners of the end face of the workpiece. The camera component 2 takes pictures to detect whether there are four blue rivets 11, whether the position is correct, whether the condition is good, and whether there are scratches and burrs; then the workpiece is sent to the third inspection station 204, and the black rivets 12 on the workpiece are inspected by camera component 2. For qualified workpieces, there are two black rivets 12, and they are located on both sides of the middle position of the workpiece. The camera component 2 takes pictures to detect whether there are two black rivets 12, whether the position is correct, whether the condition is good, and whether there are scratches and burrs; then the workpiece is sent to the O-ring loading station 205, and the O-ring loading assembly places the O-ring into the O-ring placement hole 7 of the workpiece.

[0079] The workpiece is sent to the fourth inspection station 206, and the camera component three is used to detect whether the workpiece has a QR code; then the workpiece is sent to the fifth inspection station 210, and the camera component four is used to detect whether the O-ring exists in the workpiece. If it exists in the workpiece, the O-ring will protrude from the end face of the workpiece. The camera component four shoots from the side and can observe whether the O-ring exists; then the workpiece is sent to the unloading station 207, and the flipping component 9 moves the workpiece out.

[0080] Please focus on Figure 5 and 6 The feeding component 3 includes a single-axis robot 305, on which a tooling 209 is installed, and one end of the single-axis robot 305 is surrounded by a limit frame 301, and a safety grating 302 and a photoelectric sensor 1 303 are installed on the inner wall of the limit frame 301. The safety grating 302 is used to detect the staff's insertion action, and the photoelectric sensor 1 303 is used to detect whether the workpiece is in place. Alarm lights 306 and buttons 304 are respectively installed on both sides of the limit frame 301, and a photoelectric sensor 2 307 is provided at the other end of the single-axis robot 305.

[0081] In the initial state, the tooling 209 is located in the limit frame 301, and the workpiece is placed on the tooling 209 manually. At this time, the safety grating 302 senses the insertion action, and the photoelectric sensor 303 senses the workpiece, transmits a signal, and turns on the single-axis robot 305, and the single-axis robot 305 sends the workpiece to the other end; if only the safety grating 202 senses the insertion action, but the photoelectric sensor 303 does not detect the workpiece, the alarm light 306 starts to sound an alarm to notify the staff to check; if an accident occurs during transportation, the staff can press the button 304 to stop the single-axis robot 305 from continuing to transport.

[0083] When the photoelectric sensor 2 307 senses the workpiece, the three-axis module 1 2013 drives the finger clamp cylinder 4 2014 to move to the workpiece, and the finger clamp cylinder 4 2014 clamps the workpiece, and then drives the workpiece to move to the laser coding and resistance testing machine 2011 for laser coding and resistance testing.

[0084] Please focus on Figure 7 The camera assembly 1 includes a bracket 2021 installed on the workbench 1, an aperture 2022 and a camera 2023 installed on the bracket 2021.

[0085] Please focus on Figure 8 The camera assembly 2 includes a support frame 2032 mounted on the workbench 1, a condenser 2031 and a second camera 2034 are movably mounted on the support frame 2032 through a slide rail 2033, and an aperture 2035 is installed at the bottom of the condenser 2031. The use of the condenser 2031 can focus the light to a smaller area, improve the brightness of a specific area, and thus facilitate the detection of the conditions of the blue rivet 11 and the black rivet 12.

[0086] Please focus on Figure 9-11 The O-ring feeding assembly includes an O-ring discharging component and a transfer component mounted on the workbench 1, and a limiter component mounted on the small indexing plate 208. The O-ring discharging component discharges the O-ring, and then the transfer component grabs the O-ring and places the O-ring through the limiter component to the O-ring placement hole 7 of the workpiece.

[0087] The O-ring discharging component includes a vibrating material plate 2051, a feeding channel 2052 connected to the discharging port of the vibrating material plate 2051, a fixed column 2056 located at the other end of the feeding channel 2052 and installed on the workbench 1, and a shelf plate 2058 movably installed on the fixed column 2056 by a sliding cylinder 2057. The shelf plate 2058 is provided with a groove 2059, and the groove 2059 is used to place the O-ring.

[0088] The O-ring is output from the feed channel 2052 to the groove 2059, and then the slide cylinder 2057 is turned on, so that the slide cylinder 2057 drives the shelf plate 2058 to move to the side. At this time, the outer wall surface of the shelf plate 2058 presses against the O-ring on the rear side to prevent the subsequent O-ring from being driven out of the feed channel 2052. At the same time, the transfer component sucks away the O-ring placed in the groove 2059 and transfers it to the workpiece through the limit assembly.

[0089] The transfer assembly includes a rack 2053 mounted on the workbench 1, and the suction head 2055 is mounted on the rack 2053 through a three-axis module 2054.

[0090] When the slide cylinder 2057 drives the shelf plate 2058 to move sideways, the suction head 2055 sucks the O-ring in the groove 2059.

[0091] The limiting assembly includes a limiting tube 20511 installed on the small dividing plate 208 through the three-axis module 20510.

[0092] The three-axis module 20510 drives the limiting tube 20511 to move to the top of the O-ring placement hole 7. The limiting tube 20511 is used to limit the movement of the O-ring, so as to ensure that the O-ring falls into the O-ring placement hole 7. When the suction head 2055 sucks the O-ring, the suction head 2055 drives the O-ring to pass through the limiting tube 20511 and put it into the O-ring placement hole 7. Then the suction head 2055 is closed, and the three-axis module 2 2054 drives the suction head 2055 to press the O-ring into the O-ring placement hole 7, so as to prevent the O-ring from falling out.

[0093] Please focus on Fig.12 The camera assembly three includes a camera bracket 2064 mounted on the workbench 1, a camera three 2065 and an aperture three 2063 mounted on the camera bracket 2064, and a cylinder one 2062 mounted on the small dividing plate 208 through a cylinder mounting seat 2061.

[0094] After the O-ring is placed, the cylinder 1 2062 presses the workpiece, and then the camera 3 2065 takes a picture of the QR code on the side of the workpiece to detect whether the QR code exists.
