DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments.

[0017] like Figure 1-3As shown, it is a structural schematic diagram of an embodiment of the present invention, which provides an automatic assembly detection device for a steam generator, including a feeding belt conveyor 1, a feeding robot 2, an 8-dividing turntable 3, a material transfer robot 4, and a leakage detection device 5. The feeding robot 2 includes a set of transverse pneumatic slides 14, a set of lifting pneumatic slides 15 and a set of pneumatic clamps. The transverse pneumatic slide 14 controls the lifting pneumatic slide 15 to move in the horizontal direction, and the lifting pneumatic slide 15 controls the pneumatic clamp to move in the vertical direction. The pneumatic clamp transfers the workpiece on the feeding belt conveyor 1 to the 8-dividing turntable 3. The 8-dividing turntable 3 is sequentially provided with a resistance measuring station 9, a withstand voltage measuring station 10, a visual inspection station 11, a through gauge inspection station 12, and a material unloading station 13 along the circumference. A material transfer robot 4 is provided next to the 8-dividing turntable 3. The material transfer robot 4 transfers the workpiece on the unloading station 13 to the leakage detection device 5. A total of three sets of the leakage detection device 5 are arranged. The leakage detection device 5 adopts a water detection method. The sealing cylinder seals the two outlets of the workpiece, then descends into the water, maintains the pressure for a period of time, and automatically determines whether there are bubbles through visual detection.

[0018] Furthermore, the material transfer robot 4 includes a set of transverse servo slides 16, three sets of lifting servo slides 17 and two sets of material transfer pneumatic clamps. The transverse servo slides 16 control the horizontal movement of the material transfer pneumatic clamps, and the lifting servo slides 17 control the vertical movement of the material transfer pneumatic clamps.

[0019] Furthermore, it also includes an air-blowing stamping device 18 and a material-unloading manipulator 19. The material-unloading manipulator 19 includes a set of material-unloading transverse pneumatic slides, a set of material-unloading lifting pneumatic slides and a set of material-unloading pneumatic clamps. The material-unloading pneumatic clamps move up and down on the material-unloading lifting pneumatic slides, and the material-unloading lifting pneumatic slides move horizontally on the material-unloading transverse pneumatic slides. The air-blowing stamping device 18 includes an exhaust filtration system and a stamping device. The exhaust filtration system automatically extracts and filters the water vapor on the surface of the workpiece, and the stamping device automatically puts the stamp on the workpiece after it is dipped in ink in the ink cartridge.

[0020] Furthermore, the two detection heads of the resistance meter of the resistance measuring station 9 are driven by a cylinder and connected to two terminals on the workpiece.

[0021] Furthermore, the two detection heads of the pressure tester at the pressure test station 10 are driven by a cylinder and connected to two terminals on the workpiece.

[0023] Furthermore, a through gauge is disposed at each end of the through gauge inspection station 12 and is driven by a cylinder to be inserted into the workpiece hole.

[0024] The working principle is as follows: the device uses the loading belt conveyor 1 to load materials. The steam generator is sent to the loading belt conveyor 1 by the previous process. The loading robot 2 automatically grabs the workpiece from the loading belt conveyor 1 and places it on the positioning fixture of the 8-dividing turntable 3. After completing the inspection of all workstations, the material transfer robot 4 grabs it and places it on the leakage detection device 5 for leak detection. Qualified parts are grabbed by the material transfer robot 4 and placed on the air blowing and stamping device 18. Unqualified parts are grabbed by the unloading robot 19 and placed on the unqualified parts conveyor 6. At the air blowing and stamping position, the product is first blown and then stamped. The stamped workpiece is grabbed by the unloading robot 19 and placed on the qualified part unloading belt conveyor 7.
