Description

Technical Field

[0001] The utility model relates to the technical field of radiator processing, in particular to a radiator airtightness detection device. Background Art

[0002] Radiator is a general term for a series of devices used to conduct and release heat. Its working principle is to dissipate heat through conduction, convection and radiation. In order to ensure the performance and quality of the radiator, a tightness test will be carried out after processing. This test can ensure that there are no air leaks in the radiator during the production process, discover potential quality problems in advance, and simulate extreme conditions to test the stability of the radiator. Since the heat pipe and the heat fins need to be welded, if there is a weld leak, the water in the water chamber will enter the heat belt from the gap between the heat pipe and the heat fin, which will cause corrosion to the heat belt.

[0003] Currently, during the inspection of the airtightness of the radiator, the staff will sink the radiator into a water tank, and then ventilate the inside of the radiator. After observing the leaking position, the staff can take out the radiator and repair the leaking position. However, with the current inspection method, the staff mostly rely on manual visual inspection and are unable to mark the leaking position of the radiator in time, which results in the staff being unable to accurately find the repairing position during repairing, causing inconvenience to the subsequent repairing work.

[0024] The utility model uses the thermal sensing camera 9 to photograph the radiator body 12, and by passing hot air, the thermal sensing camera 9 can capture the leakage position of the radiator, and the radiator body 12 is sunk into the inside of cold water for detection, thereby increasing the temperature difference, making it easier for the thermal sensing camera 9 to capture the radiator body and display it as a clear image. After the detection is completed, the staff can accurately repair the leaking position of the radiator body 12 according to the displayed image, which provides convenience for the staff.

[0025] Specifically, the horizontal moving structure 5 includes a rack plate 51, a mounting frame 52, a motor 53 and a first gear 54. The rack plate 51 is fixed to the front and rear sides of the top of the detection pool 1, the mounting frame 52 is fixed above the surface of one side of the moving frame 6, the motor 53 is fixed to the surface of the mounting frame 52, and the first gear 54 is fixed to the surface of the output shaft of the motor 53, and the first gear 54 is meshed with the rack plate 51. With the above design, after the staff turns on the motor 53, the output shaft of the motor 53 drives the first gear 54 on one side to rotate. Since the first gear 54 is meshed with the rack plate 51, the mounting frame 52 drives the moving frame 6 to move in the left and right directions, and the shooting detection position is adjusted horizontally.

[0026] The first bevel gear 72 is rotatably connected to the top of the interior of the moving frame 6, and the top of the reciprocating threaded rod 71 is fixedly connected to the first bevel gear 72. The connecting shaft 73 is fixed to the surface of one side of the first gear 54, and one end of the connecting shaft 73 passes through the interior of the moving frame 6. The second bevel gear 74 is fixed to the end of the connecting shaft 73 away from the first gear 54, and the second bevel gear 74 is meshed with the first bevel gear 72. The lifting block 75 is threadedly connected to the top of the surface of the reciprocating threaded rod 71, and the lifting block 75 is fixedly connected to the surface of the mounting platform 8. The surfaces on the left and right sides of the moving frame 6 are provided with guide grooves 13. Guide blocks 14 are fixed to the left and right sides of the lifting block 75, and one side of the guide block 14 extends to the interior of the guide groove 13 and is slidably connected to the inner wall of the guide groove 13.

[0027] In the above design, when the first gear 54 rotates, the connecting shaft 73 drives the second bevel gear 74 to rotate, thereby causing the first bevel gear 72 to rotate as well. The guide blocks 14 on both sides limit the lifting block 75, so that the lifting block 75 can only move up and down, thereby adjusting the shooting detection height of the thermal sensing camera 9.

[0028] Specifically, the shooting angles of the thermal sensing cameras 9 on the front and rear sides of the detection pool 1 are different, and the shooting angle of the thermal sensing camera 9 on the rear side is tilted upward, while the shooting angle of the thermal sensing camera 9 on the front side is tilted downward. With the above design, when the thermal sensing cameras 9 on both sides move up and down, the shooting angles of the thermal sensing cameras 9 on both sides are different, so that different positions of the radiator body 12 can be effectively photographed and detected.

[0029] Specifically, both the front and rear sides of the inner wall of the fixing frame 10 are provided with limit slots 15, and both the front and rear sides of the support platform 11 are fixed with limit blocks 16, and the limit blocks 16 are located inside the limit slots 15 and are slidably connected to the inner wall of the limit slots 15. With the above design, the staff can drag the position of the support platform 11 back and forth according to the size of the radiator to be detected, and the limit blocks 16 slide inside the limit slots 15 to control the range of movement of the support platform 11.

[0030] Working principle: When the staff is testing the airtightness of the radiator, the staff first places the radiator to be tested on the top of the support 11, and then the staff pulls the hot air duct 3 and the exhaust pipe 4 on both sides to connect the hot air duct 3 and the exhaust pipe 4 with the pipes on the surface of the radiator body 12. After the connection is completed, the staff can pour cold water into the interior of the detection pool 1, and then the staff can turn on the thermal sensing cameras 9 on the front and back sides, and pass hot air from the hot air duct 3, so that the hot air enters the interior of the radiator body 12. At this time, the staff turns on the motors 53 on both sides, so that the movable frame 6 moves back and forth left and right, and the thermal sensing cameras 9 on the front and back sides move up and down, and the surface of the radiator body 12 is photographed back and forth by the thermal sensing cameras 9 on both sides, and the photographed image is displayed on the surface of the touch display screen 2. When the shooting is completed, the staff removes the radiator body 12, and then the staff can perform repair welding on the leaking area according to the image display on the top of the touch display screen 2, so as to complete the inspection operation of the radiator.
