The worker needs to place the copper tube 16 on the first conveyor belt 10 according to the requirement that the tube head is on the left, and then the copper tube 16 moves to the right on the first conveyor belt 10. The rightward displacement of the control cylinder 5 can drive the interception plates 9 of the rotating sleeve 8 to rotate counterclockwise one by one and be flush with the first conveyor belt 10, thereby blocking the copper tube 16. After rotating four interception plates 9 one by one, the first conveyor belt 10 stops. At this time, there will be four copper tubes 16 flush on the first conveyor belt 10, and then the first support The frame 13 slides forward on the second slide rail 12 and controls the clamping hand 19 at the bottom to descend and clamp the copper tube 16, and then drives the copper tube 16 to be inserted into the fixed tube 30. After the edge is fixed by the sealing ring 29, air is input into the copper tube 16 by the air pump 31. The internal pressure value is detected by the detection tube 32 to determine whether there is damage. Before transporting the copper tube 16, the adsorption plate 46 will adsorb the fins on the second conveyor belt 35 and follow the first support frame 13 to be transported to the rear third conveyor belt 47. The detection machine 48 is used to detect whether the surface and the back are damaged, so as to achieve the effect of simultaneously detecting two sets of necessary components, improve the detection efficiency, and reduce the damage rate of finished products.

[0030] An extension bracket 2 is fixedly installed above the base 1, a fourth conveyor belt 4 is arranged above the extension bracket 2, a moving block 3 is arranged on the outer side of the fourth conveyor belt 4, a control cylinder 5 is slidably arranged above the extension bracket 2, the moving block 3 and the control cylinder 5 are fixedly connected to each other, a control console 7 is fixedly installed above the base 1, the control console 7 is rotatably connected to the rotating sleeve 8, a track groove 6 is arranged on the outer side of the control cylinder 5, the end of the intercepting plate 9 is slidably connected to the track groove 6, the first conveyor belt 10 is arranged above the base 1, the fourth conveyor belt 4 will rotate when it is started, so as to drive the control cylinder 5 to move to the right through the moving block 3, the rotating sleeve 8 itself can rotate with the intercepting plate 9, because the end of the intercepting plate 9 is inserted in the track groove 6, so when the control cylinder 5 moves to the right, the end of the intercepting plate 9 will be affected by the trajectory of the track groove 6, and the track The groove 6 is composed of two sections. When the end of the interception plate 9 is in the track groove 6 on the side, it will be lowered and flush with the first conveyor belt 10, otherwise it will be in a vertical state. Therefore, after the worker places the copper tube 16 as required, the control cylinder 5 begins to move slowly and continuously, first lowering the rightmost interception plate 9. When the copper tube 16 moves to the inside of the rightmost interception plate 9, it will be blocked. Due to the continuous thrust of the first conveyor belt 10, the copper tube 16 will fit the interception plate 9, thereby achieving the effect of deviation correction. With the continuous displacement of the control cylinder 5, the track groove 6 drives the second interception plate 9 to fall, and the second copper tube 16 can be intercepted at this time. After repeating four times, four copper tubes 16 will be intercepted, and then the first conveyor belt 10 will stop and wait for grabbing and transportation, thereby achieving the effect of automatic deviation correction and intercepting the copper tubes 16 one by one to wait for detection according to the specified position, thereby improving efficiency.

[0031] A heightening rod 11 is fixedly installed above the base 1, and the upper part of the heightening rod 11 is connected to the second slide rail 12, a first transfer frame 14 is arranged on the front side of the first support frame 13, a balance plate 15 is slidably connected in front of the first transfer frame 14, and the bottom of the balance plate 15 is connected to the clamping hand 19, a copper tube 16 is placed above the first conveyor belt 10, a first cylinder 17 is arranged above the base 1, and a push head 18 is arranged at the gas rod end of the first cylinder 17;

[0032] A second transfer frame 36 is provided at the rear side of the first support frame 13, a sliding groove 37 is provided at the rear side of the second transfer frame 36, a guide rail 38 is provided on the inner side of the sliding groove 37, a threaded shaft 39 is provided inside the sliding groove 37, a slider 40 is slidably connected to the outer side of the guide rail 38, the slider 40 and the threaded shaft 39 are slidably connected to each other, a first bevel gear 41 is connected to the left bearing of the slider 40, the first bevel gear 41 and the threaded shaft 39 are threadedly meshed with each other, a second bevel gear 42 is connected to the left bearing of the slider 40, the second bevel gear 42 and the first bevel gear 41 are meshed with each other, and the rear of the second bevel gear 42 is connected to the left bearing of the slider 40. A rotating plate 43 is arranged on the side, and a lifter 44 is arranged on the rear side of the rotating plate 43. A lifter 45 is slidably connected inside the lifter 44. The bottom of the lifter 45 is connected to the adsorption plate 46. When the inspection of the copper tube 16 is completed, the first cylinder 17 pushes the internal gas rod to drive the push head 18 to push the copper tube 16 forward, so that it leaves the inspection area and is pushed back onto the first conveyor belt 10. After the inspection is completed, the first support frame 13 moves forward on the second slide rail 12, driving the first transfer frame 14 to arrive on the first conveyor belt 10, and then the balance plate 15 descends, and the four groups of copper tubes 16 are clamped by the clamping hand 19. After that, the first support frame 13 starts to move backward, driving the copper tube 16 to move into the detection area. When the first support frame 13 moves forward on the second slide rail 12, the second transfer frame 36 will also move with it and reach above the second conveyor belt 35. Then the lifter 44 controls the lifting rod 45 to lower the adsorption plate 46 to adsorb the fins on the second conveyor belt 35, and then continues to move backward with the first support frame 13, driving the fins to reach above the third conveyor belt 47, and then waits for it to be detected. Since the fins have both front and back sides to be detected, when the single-sided detection of the fins is completed, the lifter 44 controls the lifting rod 45 to lower the adsorption plate The adsorption fin 46 then rises and returns to its original position, and then the slider 40 moves to the right on the sliding groove 37. During the displacement process, the middle first bevel gear 41 will be driven to rotate due to the position restriction of the bearing connection and the meshing connection relationship with the threaded shaft 39, thereby driving the second bevel gear 42 to rotate, so that the rotating plate 43 rotates, thereby driving the fin to flip through the adsorption plate 46, achieving the effect of flipping by backward displacement. The overall device realizes the transportation of the two components to be detected and the flipping operation of the fin through the displacement of the first support frame 13 on the second slide rail 12, which has good practicality and high efficiency.

[0033] A test platform 20 is arranged above the base 1, a pad 21 is arranged above the test platform 20, a support plate 22 is arranged above the test platform 20, a second cylinder 23 is arranged above the support plate 22, a fixed plate 24 is arranged at the gas rod end of the second cylinder 23, a buffer cylinder 25 is arranged above the fixed plate 24, a fixed head 26 is arranged at the buffer rod end of the buffer cylinder 25, a third cylinder 27 is arranged above the support plate 22, and the gas rod end of the third cylinder 27 is connected to the sealing ring 29.

After the copper tube 16 is driven into the detection area, it will be inserted into the fixed tube 30 through the auxiliary ends of the guide groove 28, and then the second cylinder 23 is started to drive the fixed plate 24 to descend through the gas rod, and the fixed plate 24 is driven to move downward. The bottom fixed head 26 presses the copper tube 16 on the pad 21 to fix it, preventing displacement during confidential detection, resulting in detection failure and inaccuracy. At the same time, when pressing the copper tube 16, prevent the fixed head 26 from crushing the copper tube 16. When the pressing force is too large, the fixed head 26 will shrink in the buffer cylinder 25 to reduce the pressure. Then the third cylinder 27 starts to drive the downward pressure sealing ring 29 through the gas rod to seal the connection between the copper tube 16 and the fixed tube 30 to prevent leakage during detection. Then the air pump 31 starts to input a certain amount of gas into the tube, and the internal air pressure of the copper tube 16 slowly increases. At this time, the internal pressure of the detection tube 32 increases accordingly and pushes the detection head 34 outward. At this time, the detection head 34 contacts the sensor 33, indicating that the internal air pressure is at a specified value at this time. Then the air pump 31 is locked. After waiting for a period of time, if the detection head 34 is separated from the sensor 33, it means that the copper tube 16 is damaged and leaking, and it is necessary to inform the staff to handle it, so as to achieve the effect of using the air pump 31 to increase the internal air pressure to achieve airtight detection, which is simple and fast.

[0034] The third conveyor belt 47 is fixedly installed above the base 1, and a second support frame 49 is arranged above the detection machine 48.
