DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Refer to the attached specification Figure 1-3 The utility model is a laser weld nondestructive testing device, comprising a support rod 1, see Figure 1 , a detection piece 2 is fixedly installed on the top of the support rod 1. The setting of the detection piece 2 is improved. The detection piece 2 can detect the length and width of the weld, and establish big data association with the welding penetration and width. The detection piece 2 can detect the length and width of the weld through 3D vision to determine the welding quality. The detection method does not damage the product. If the welding process is abnormal, the length and width of the weld do not meet the product specifications, the weld will be abnormally protruding. The laser reflection angle of 3D vision can detect the abnormally protruding weld. Through 3D detection of the module weld, the welding quality can be quickly determined. A control panel 3 is fixedly installed on one side of the detection piece 2. A support plate 4 is provided on one side of the support rod 1. A fixing plate 5 is fixedly installed on one side of the support plate 4. A motor 6 is fixedly installed on the top of the fixing plate 5. The output shaft of the motor 6 is fixedly connected to a rotating rod 7. The rotating rod 7 is rotatably connected to the inside of the support plate 4. A guide plate 8 is fixedly installed on the top of the support plate 4. A conveyor belt 9 is sleeved on the outer wall of the rotating rod 7. A toothed belt 10 is fixedly installed on the outer wall of the conveyor belt 9. See Figure 3 A gear 11 is provided on the top of the conveyor belt 9 , the gear 11 is meshed with one side of the toothed belt 10 , and a placement plate 12 is fixedly installed on the top of the gear 11 .

[0021] It should be noted that, when the staff needs to inspect the weld of the product, the staff can start the detection device to start the detection member 2 and the motor 6 to work, and then the motor 6 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the conveyor belt 9 to rotate. The rotation of the conveyor belt 9 will drive the toothed belt 10 to move together. At this time, the staff can place the product on the placement plate 12 and place the placement plate 12 on the top of the conveyor belt 9 through the gear 11, so that the conveyor belt 9 drives the gear 11 to move together, and then the gear 11 is driven by the conveyor belt 9 to be relatively pushed by the guide plate 8, so that the gear 11 is limited between the guide plates 8 and meshes with the toothed belt 10. When the gear 11 is driven by the conveyor belt 9 to enter the bottom of the detection member 2 After the blocking member 13 is blocked by the placement plate 12, the conveyor belt 9 cannot drive the gear 11 to continue moving, so that the toothed belt 10 on the conveyor belt 9 will drive the stopped gear 11 to rotate, and the rotation of the gear 11 will drive the product to rotate through the placement plate 12, so that the weld on the product can be fully inspected by the detection member 2, and then the detection member 2 can detect the weld on the product in different directions, allowing the detection member 2 to more comprehensively detect the shape, width and length of the weld, so as to determine whether the weld on the product meets the product regulations, so as to improve the detection effect of the product weld and prevent errors in the detection. Finally, the detection member 2 displays the results through the control panel 3, which is convenient for the staff to determine.

[0022] Embodiment 2: The top of the guide plate 8 is rotatably connected to two stops 13, one of which is arranged on the outer wall of the placing plate 12, and a half gear 14 is fixedly connected to the bottom of the stopper 13, and the half gear 14 is rotatably connected to the inside of the support plate 4, and a rack 15 is arranged on the outer wall of the half gear 14, and the rack 15 is slidably connected to the inside of the support plate 4, and two limit rods 16 are fixedly connected to the outer wall of the rack 15, and the two limit rods 16 are inserted into the inside of the corresponding stops 13, and a spring 17 is fixedly installed on one side of one of the limit rods 16, and the spring 17 is fixedly installed in the inside of the support plate 4, and a guide rod 18 is fixedly connected to the inside of the support plate 4, and the guide rod 18 is inserted in the inside of the spring 17, and the guide rod 18 is inserted in the inside of one of the limit rods 16, and a handle 20 is fixedly connected to the top of one of the limit rods 16, and the handle 20 is slidably connected to the top of the guide plate 8.

[0023] It should be noted that when the gear 11 is driven by the toothed belt 10 to rotate, the gear 11 will drive the double-layer gear 19 to rotate together, so that the double-layer gear 19 drives the rack 15 to slide along the inside of the support plate 4, and then the rack 15 drives the limiting rod 16 to gradually disengage from the inside of the stopper 13. When the gear 11 is driven by the toothed belt 10 to rotate one circle, the double-layer gear 19 will pull the limiting rod 16 out of the inside of the stopper 13 through the rack 15. At this time, the stopper 13 loses its limit, allowing the conveyor belt 9 to drive the gear 11 to continue moving, and the placement plate 12 pushes the stopper 13 away, so that the product that has been inspected can be driven away from the bottom of the inspection piece 2, and then the product that has not been inspected can push another stopper 13 to enter the bottom of the inspection piece 2 for inspection, so as to achieve the effect of automatically changing the inspection product and improve the inspection efficiency of the product weld. At the same time, when the stopper 13 is pushed by the placement plate 12 to rotate, the stopper 13 will drive the semi- The gear 14 meshes with the rack 15 and drives the rack 15 to continue to slide along the inside of the support plate 4. It should be noted that when the rack 15 slides along the inside of the support plate 4, the rack 15 will drive a limit rod 16 to squeeze the spring 17 to contract. When the product that has been tested is driven by the gear 11 and the placement plate 12 to separate from the bottom of the detection member 2, and the new product is driven to the bottom of the detection member 2, the stopper 13 will lose the squeezing of the placement plate 12, so that the spring 17 can push the rack 15 to reset through the limit rod 16, and then the rack 15 drives the half gear 14 to rotate and reset, and the half gear 14 drives the stopper 13 to reset. At this time, the card slot on the stopper 13 will be realigned with the limit rod 16, so that the limit rod 16 can be pushed by the spring 17 and finally reinserted into the inside of the stopper 13, and the rotation of the stopper 13 is limited, and the product that has newly entered the bottom of the detection member 2 is tested, and then it loses the limit again and can be opened;

[0024] When the detection device is just started, the staff can pull the handle 20 so that the handle 20 pulls the rack 15 to move along the inside of the support plate 4 through the limit rod 16 connected thereto, and finally the blocker 13 loses the limit of the limit rod 16, so that the gear 11 and the placement plate 12 that drive the first product can push the blocker 13 to enter the bottom of the detection part 2. When the gear 11 and the placement plate 12 drive the product into the interior of the detection part 2, the staff can release the handle 20 to allow the spring 17 to drive the rack 15 to reset, and finally the blocker 13 blocks the subsequent gears 11 and the placement plate 12 again, and prevents the gear 11 and the placement plate 12 that enter the bottom of the detection part 2 from driving the product to be driven by the conveyor belt 9 directly out of the bottom of the detection part 2, causing the product to leave the bottom of the detection part 2 before the detection is completed.
