Description

Technical Field

[0001] The utility model relates to the technical field of sealing detection, in particular to a sealing detection device of a laser profile sensor. Background Art

[0002] Laser profile sensor is a laser profile sensor sealing detection device. It is a sensor that realizes non-contact high-precision measurement of the target's two-dimensional profile based on the principle of laser triangulation. The laser profile sensor uses the characteristics of the laser beam. The line laser emitted by the laser diode is focused and collimated by the transmitting lens group and irradiated onto the target to be measured. The laser beam forms a contour line on the surface of the target to be measured. After the contour line passes through the imaging lens group, it is imaged on the array photoelectric receiver (such as CCD / CMOS, etc.). The laser profile sensor can accurately identify poorly sealed products by acquiring high-quality point cloud images. For example, in the sealing detection of yogurt, the sensor can identify sealing problems that may cause yogurt to overflow, contaminate, and deteriorate. In the auto parts industry, laser profile sensors can be used to detect defects in automotive seals / gaskets, such as excess or lack of meat. These defects will affect the sealing performance of the seal, and then affect the overall sealing of the car.

[0003] In actual use, the laser contour sensor can convey the object to be inspected to the bottom of the laser contour sensor through the assembly line, and directly inspect the appearance of the object to be inspected from top to bottom through the laser contour sensor. However, during the inspection process, one side is still pressed on the conveyor belt, and the laser contour sensor cannot fully inspect the object to be inspected, which greatly reduces the success rate of detection.

[0019] Reference Figure 1-Figure 3 A laser profile sensor sealing detection device includes a box body 1 placed on the ground, a support frame 2 is fixedly connected to the top of the box body 1, evenly distributed columns 3 are arranged at both ends of the box body 1, a conveyor belt 4 is fixedly connected to the top of the column 3, a laser profile sensor 5 is fixedly connected to the top of the inner wall of the support frame 2, symmetrically distributed slide grooves 6 are opened on both sides of the support frame 2, a first motor 7 is fixedly connected to the bottom end of the inner wall of the slide groove 6, and the first motor 7 is connected to a rotating clamping plate 8 through a flip structure.

[0020] It should be noted that the first motor 7, infrared sensor 9, second motor 14, and electric push rod 17 are existing technologies. The specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0021] Furthermore, infrared sensors 9 are arranged on both sides of the inner wall of the support frame 2 , and the infrared sensors 9 are arranged at the entrance of the support frame 2 .

[0022] After the object to be detected passes through the infrared sensor 9, the infrared sensor 9 transmits a signal to the control center, and the control center starts the laser profile sensor 5 and the flip structure to work.

[0023] Furthermore, the flipping structure includes a symmetrically distributed lead screw 10, a slider 11, a connecting block 12, a placement cavity 13, a second motor 14, a first bevel gear 15, a second bevel gear 16, and an electric push rod 17. The lead screw 10 is fixedly connected to the output end of the first motor 7, and the slider 11 is slidably connected to the inner wall of the slide groove 6.

[0024] Among them, the first motor 7, the lead screw 10 and the slider 11 are all symmetrically distributed and both are separately arranged structures and can operate independently. The movement of the left slider 11 does not affect the movement of the right slider 11.

[0025] Furthermore, the connecting block 12 is fixedly connected to the outer wall of the slider 11, the placement cavity 13 is arranged at the top of the connecting block 12, the second motor 14 is fixedly connected to the bottom end of the inner wall of the placement cavity 13, the first bevel gear 15 is fixedly connected to the output end of the second motor 14, and the second bevel gear 16 is rotatably connected to the outer wall of the connecting block 12.

[0026] The above is a rotating component in the flip structure, which drives the first bevel gear 15 to rotate through the second motor 14, the first bevel gear 15 drives the second bevel gear 16 to rotate, the second bevel gear 16 drives the electric push rod 17 to rotate, and then drives the rotating clamping plate 8 to rotate.

[0027] Furthermore, the electric push rod 17 is fixedly connected to the outer wall of the second bevel gear 16 , and the rotating clamping plate 8 is fixedly connected to the telescopic end of the electric push rod 17 .

[0028] The rotating clamping plate 8 can be rotated so that the electric push rods 17 on both sides can move on different horizontal planes, so that the object to be detected can be cut at a certain angle.

[0029] Furthermore, the lead screw 10 is rotatably connected to the inner wall of the slide groove 6 , the slider 11 is threadedly connected to the lead screw 10 , and the first bevel gear 15 and the second bevel gear 16 are meshed with each other.

[0030] The flipping structure is achieved by starting the first motor 7, which drives the lead screw 10 to rotate, and the lead screw 10 drives the slider 11 to move up and down, thereby driving the rotating clamping plate 8 to move up and down.

[0031] Working principle: first, place the object to be detected on the conveyor belt 4, and then drive the object to be detected to move from right to left. Then, when the object to be detected passes through the infrared sensor 9, the infrared sensor 9 transmits a signal to the control center. The control center starts the laser profile sensor 5 and the flipping structure to work. The flipping structure is started by starting the electric push rod 17. The electric push rod 17 extends forward and pushes the rotating clamping plate 8 to clamp the object to be detected. Then, the first motor 7 is started. The first motor 7 drives the lead screw 10 to rotate, and the lead screw 10 drives the slider 11 to move up and down. Then, when it is necessary to flip over for detection, the second motor 14 can be started. The second motor 14 drives the first bevel gear 15 to rotate, and the first bevel gear 15 drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the electric push rod 17 to rotate, and then drives the rotating clamping plate 8 to rotate. The rotating clamping plate 8 drives the object to be detected to flip, so that the laser profile sensor 5 can detect the object to be detected more comprehensively, and the success rate of detection is greatly improved.
