Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple detection equipment, in particular to a thermocouple detection equipment capable of batch detection. Background Technique

[0002] Before leaving the factory, thermocouples need to be subjected to centralized product detection, generally including thermoelectric effect detection, appearance detection, cable detection, nitrogen filling detection, etc. When inspecting the appearance, not only is it necessary to check whether its outer surface is complete, whether the surface is flat and smooth, without damage such as cracks, notches, and deformations, but also the steel protective sleeve of the thermocouple needs to be inspected;

[0003] Since the protective sleeve plays a protective role for the thermocouple, its integrity is crucial for the long-term use of the thermocouple. Therefore, it is necessary to check the installation condition and the shape of the protective sleeve to prevent cracks in the protective sleeve from causing the inability to provide protection for internal components during later use. Generally, before assembling the existing thermocouple protective sleeve, a pressure test for leak detection or direct observation is used to detect whether there are cracks in the protective sleeve. However, during the overall assembly of the thermocouple later, both the protective sleeve and the assembled thermocouple will be transferred through a conveying device to the subsequent processing process. During this process, some thermocouples or protective sleeves will collide with each other during transportation and transfer, which may cause deformation or even cracks in the protective sleeves of some thermocouples. During this process and the detection process of the thermocouple finished product, due to the different sizes of the ends of the thermocouple and the protective sleeve, it is impossible to centrally provide a rapid appearance detection for the protective sleeve of the thermocouple.

[0025] like Figure 1 As shown, two material discharge buffer rods 13 are also provided on one side of the detection frame 2, one end of the two material discharge buffer rods 13 are respectively fixedly installed on the ground, and the other ends of the two material discharge buffer rods 13 are respectively extended to one side of two guide rods 10;

[0026] like Figure 1 , Figures 3 - 4As shown, the L-shaped mounting plate 7 is fixedly mounted on the detection frame 2, two fixing blocks 14 are fixedly mounted on one side of the L-shaped mounting plate 7, and one of the fixing blocks 14 is wider than the other fixing block 14, first slots 15 are provided on both sides of the fixing seat 9, the fixing seat 9 is inserted and installed between the two fixing blocks 14 through the first slots 15 on both sides, and the first slots 15 are inserted and installed on the corresponding fixing blocks 14, the fixing seat 9 is inserted and installed between the two fixing blocks 14 through the first slots 15 on both sides, and the fixing block 14 with a larger width is also inserted and installed in the first slots 15 on one side of the adjacent fixing seat 9, which can improve the connection stability between multiple L-shaped mounting plates 7;

[0027] like Figure 1 , Figure 3 , Figures 5 - 7 As shown, second slots 17 are provided on both sides of the guide rod 10, a guide slot 18 is provided on the guide rod 10 located above one of the second slots 17, a limiting slot 19 is provided on one side of the guide slot 18, and a mounting slot 20 is provided on the guide rod 10 located above the other second slot 17. Both sides of the C-shaped mounting rod 11 are respectively inserted and installed in the corresponding second slots 17 and fixed by screws, and the center position of the side of the C-shaped mounting rod 11 away from the guide rod 10 is fixedly installed on the output end side of the corresponding cylinder 8. With the cooperation of the cylinder 8, the cylinder 8 can pull the guide rod 10 to the side of the L-shaped mounting plate 7 through the C-shaped mounting rod 11, thereby Unqualified thermocouples are excluded. A side rib 21 is fixedly installed on one side of the limit block 12. A vertical mounting hole 22 is opened in the side rib 21. A mounting screw 23 is inserted and installed in the mounting hole 22. The bottom of the mounting screw 23 passes through the mounting hole 22 and is threadedly connected to the top side of the C-shaped mounting rod 11. The mounting screw 23 between the C-shaped mounting rod 11 and the limit block 12 is sleeved with a compression spring 24. The limit block 12 can automatically eject the limit block 12 when the limit groove 19 does not limit the side rib 21 with the help of the force of the compression spring 24, so that when the corresponding two guide rods 10 discharge the unqualified thermocouples, the subsequent thermocouples are prevented from sliding and falling.

[0028] like Figure 2 As shown, the output ends of the cylinders 8 at two side positions are respectively fixedly installed with arc-shaped limit blocks 16, and the arc-shaped limit blocks 16 are inserted and installed on one side of the corresponding unloading buffer rod 13. With the help of the cooperation between two of the cylinders 8 and the arc-shaped limit blocks 16, the thermocouples sliding onto the multiple guide rods 10 can be limited in downward movement, which is convenient for detection by the visual inspection camera 5.

[0029] It should be noted that the present utility model is a thermocouple detection device capable of batch detection. When performing an appearance inspection on the assembled thermocouple protective sleeve, the thermocouple can be conveyed towards the detection frame 2 through the conveyor 1. Since the thermocouple on the conveyor 1 is restricted by the width of the conveyor 1, the placement direction of the thermocouple moves along with the conveying direction of the conveyor 1. When the thermocouple is conveyed through the conveyor 1 to between multiple guide rods 10 on both sides of the top of the detection frame 2, due to the relatively large size of the end of the thermocouple, the end of the thermocouple will slide on the tops of the two guide rods 10, while the protective sleeve part of the thermocouple will freely droop by gravity and be located between the two guide rods 10. Then, the thermocouple slides to one side between the multiple guide rods 10, and the first thermocouple is limited by the two arc-shaped limit blocks 16. Subsequently, subsequent thermocouples slide between the multiple guide rods 10 in the same manner as described above. Then, the control computer 3 synchronously detects the appearance of the protective sleeves of multiple thermocouples through multiple vision detection cameras 5, and preprocesses the collected images, including denoising, enhancing contrast, adjusting gray levels, etc. Then, an image processing algorithm such as a crack extraction method based on morphology is used to analyze the preprocessed images to extract the characteristics of the cracks. When it is detected that the outer sheath of one of the thermocouples is deformed or cracked, the control computer 3 controls the corresponding two cylinders 8 to start. Then, the output ends of the two cylinders 8 respectively pull the corresponding C-shaped mounting rods 11 to one side, thereby causing the C-shaped mounting rods 11 to drive the guide rods 10 on one side to move. When the current guide rod 10 moves, the limit groove 19 on one side thereof disengages from the side stop 21 of the mounting hole 22 on one side of the adjacent guide rod 10. As a result, the mounting hole 22 on one side of the adjacent guide rod 10 is jacked up by the action of the compression spring 24. Then, after the two guide rods 10 move in opposite directions, the distance between the two guide rods 10 is greater than the diameter of the end of the thermocouple, so that the current unqualified thermocouple can be excluded, and the limit block 12 can limit the adjacent thermocouple to prevent it from sliding between the two moved guide rods 10 and falling. Subsequently, the two cylinders 8 synchronously drive the two guide rods 10 to move relatively, thereby causing the guide rods 10 to reset. Moreover, the guide groove 18 on one side of the guide rod 10 squeezes the side stop 21 of the limit block 12 on one side of the adjacent guide rod 10 downward, and finally causes the side stop 21 to move downward and penetrate into the limit groove 19, so that the limit block 12 can be received. Then, the subsequent thermocouples slide to one side. Finally, by starting two of the cylinders 8 through the control computer 3, the output ends of the two cylinders 8 respectively control the corresponding arc-shaped limit blocks 16 to move to one side, thereby causing the multiple detected thermocouples to slide and discharge through the two blanking buffer rods 13. Subsequent detections can be quantitatively conveyed in the same manner as described above.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
