[0002] Oil wood pole is a common building material, which has the advantages of light weight, corrosion resistance and processing, so it is widely used in construction projects.

[0003] Since this wood is resistant to decay, higher quality requirements are placed on the wood, so there cannot be wormholes inside the wood. Currently, ultrasonic testing is mostly used to detect wormholes in wood. Since some wood is thicker and heavier, it is difficult to straighten the wood after polishing, which makes it difficult to perform automated ultrasonic testing on the wood. At the same time, during the ultrasonic testing process, the ultrasonic generator needs to be in complete contact with the surface of the wood, so liquid needs to be filled between the wood and the ultrasonic generator. The last step in the production of oiled wood poles requires ensuring that the moisture content of the wood is low, so conventional wood wormhole detection will extend the production time of the wood. Summary of the invention

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] like Figure 1-18 The present invention discloses an ultrasonic detection-based surface defect detection device for anti-corrosion oil rods, comprising a feeding platform, a graphic acquisition device for roughly measuring the feeding state of the rod material, and a work frame 1. A processing platform 2 is arranged on the work frame 1, and a turning platform 4 is arranged at the bottom of the processing platform 2. The turning platform 4 is slidably connected in the work frame 1 and driven by a reciprocating mechanism 3. A feeding pulley 5 is arranged in the middle of the processing platform 2. A rod material clamping and regulating mechanism 6, which is installed at one end of the top of the processing table 2 and is used to clamp the rod material; A grinding device 7, which is installed in the middle of the top surface of the processing table 2, and is used to grind the outer surface of the rod material in multiple specifications; An ultrasonic detector 9, which is installed on the ultrasonic detection device 8 and is used to detect the rod material; An ultrasonic detection device 8, which is mounted on the other end of the top of the processing table 2, and is used to adjust the ultrasonic detector 9 and ensure that the ultrasonic detector 9 fits the outer surface of the rod material; The rod material clamping and regulating mechanism 6 includes an electric screw 601 and a clamping roller 606. The electric screw 601 is used to drive the clamping roller 606 to clamp the surface of the rod material. The top of the clamping roller 606 is rotatably connected to a bogie 607. Both ends of the bogie 607 are provided with steering rollers 603. An angle sensor 608 is provided at the corresponding position of the bogie 607 and the clamping roller 606 axis. When the inclined rod material is clamped by the clamping roller 606, the steering rollers 603 on both sides of the clamping roller 606 are tilted under the support of the inclined surface, and the tilt angle is collected by the angle sensor 608, which facilitates the turning table 4 to adjust the table top of the processing table 2.

[0023] Furthermore, the reciprocating mechanism 3 is composed of a ball screw and a stepping motor, and is used to drag the processing table 2 to slide reciprocally on the workbench 1.

[0024] Furthermore, the turning platform 4 is composed of a gear set and a stepper motor, which is used to drive the processing platform 2 to rotate on the top of the turning platform 4.

[0025] Furthermore, the steering roller 603 is identical to the clamping roller 606 , and the axes of the steering roller 603 and the clamping roller 606 are coplanar.

[0026] Furthermore, since there is an angle between the bogie 607 and the inclined rod material, when the clamping roller 606 clamps the rod material, one of the steering rollers 603 on the bogie 607 will contact the rod material before the clamping roller 606, thereby causing the bogie 607 to rotate as a whole.

[0027] According to the above structure, the clamping rollers 606 are driven to move toward or toward each other by the electric screw 601, so as to clamp the side wall of the wooden pole. When the clamping rollers 606 come into contact with the wood, the steering rollers 603 rotate a certain angle under the support of the end of the wood. When the angle sensor 608 detects the rotation angle, the data is synchronized to the turning platform 4, and through the operation of the turning platform 4, the gap between the two clamping rollers 606 is at a relatively minimum value.

[0028] See attached Figure 5 and attached Figure 6 The top of the electric screw 601 is slidably connected to a screw slider 602, the clamping roller 606 is rotatably connected to the clamping frame 605, a pressure sensor 604 is arranged between the screw slider 602 and the clamping frame 605, the screw slider 602 is fixedly connected to the clamping frame 605, and an elastic support pad is arranged between the screw slider 602 and the clamping frame 605.

[0029] According to the above structure, when the electric screw 601 drives the clamping frame 605 to clamp the wood surface, if the wood input position is not centered, the clamping frame 605 on one side will first contact the outer surface of the wood. At this time, the pressure value measured by the clamping frame 605 on this side is greater than that on the other side, and the moving direction of the reciprocating mechanism 3 is controlled according to the positive and negative values ​​of the difference until the difference is within a suitable range.

[0030] Further, when the corner of the processing table 2 corresponds to the rod material and the rod material is located in the center of the processing table 2, the reciprocating mechanism 3 and the feeding belt pulley 5 cooperate to convey the wood. When the wood completely penetrates the processing table 2, the wooden rod can be adjusted by rotating the processing table 2 to make the wooden rod straight. This method can cooperate with the work of the reciprocating mechanism 3 to stack the rod materials.

[0031] Refer to the appendix Figure 7 and the appendix Figure 8 As shown in the figure, on both sides of the top of the clamping bracket 605, there are sliding-connected reset sliders 610. On one side of the reset slider 610, there is a first spring 609. The two first springs 609 on both sides pull the reset slider 610 to apply force to one side plane of the bogie 607. The sliding surface between the clamping bracket 605 and the reset slider 610 is provided with a limit pin, which is used to block the movement of the reset slider 610 and ensure that the center line of the two alignment rollers 603 on both sides of the bogie 607 in the normal state intersects with the axis of the first electric screw rod 601 and is in a vertical state.

[0032] According to the above structure, when the clamping bracket 605 is dragged by the first electric screw rod 601 and moves away from the wood, the bogie 607 rotates under the pushing of the reset slider 610 until the reset slider 610 contacts the limit pin, ensuring that the position of the bogie 607 in the normal state is constant. When the alignment roller 603 on the bogie 607 contacts the wood and causes the whole bogie 607 to rotate, the bogie 607 will push the reset slider 610 to slide on the clamping bracket 605. At this time, the first spring 609 is further stretched. When it contacts and separates from the rod material, under the pulling of the first spring 609, the reset slider 610 contacts the limit pin.

[0033] Further, in the normal state, the first spring 609 pulls the reset slider 610 and contacts the limit pin.

[0034] Furthermore, a positioning sleeve is rotatably connected to the top of the reset slider 610.

[0035] Refer to the appendix Fig.10 As shown in the figure, the grinding device 7 includes a sanding frame 703. A sanding belt 702 is sleeved outside the sanding frame 703. The sanding frames 703 are arranged in pairs and parallel to each other. A slider 706 is hinged in the middle of the sanding frame 703. A guide rail 707 is fixedly connected to the slider 706. A second screw slider 709 is slidably connected to the guide rail 707. An electric screw rod 708 is fixedly connected to the processing table 2, and the electric screw rod 708 drives the second screw slider 709. Rotating shafts are provided at both ends of the sanding frame 703, and the rotating directions of the sanding belts 702 on the same side are opposite.

[0036] Furthermore, the rotation direction of the sanding frame 703 is controlled by a gear set, the power is output through a pulley, and the power source is output through a stepping motor.

[0037] Furthermore, when the sanding belts 702 on both sides are at the minimum distance, the crossing angle of the sanding frames 703 on both sides is less than one hundred and eighty degrees.

[0038] Furthermore, the swing side of the sanding frame 703 is away from the input end of the wood.

[0039] Furthermore, the transmission part between the electric screw 2 708 and the screw slider 2 709 adopts a ball screw and a ball sleeve. When the wood contacts the surface of the sanding belt 702, it can push the sanding belt 702 to swing, avoiding damage to the sanding belt 702 due to inertia of the heavier wood.

[0040] Furthermore, both ends of the electric screw 708 are provided with threads with different rotation directions.

[0041] According to the above structure, the electric screw 2 708 drives the screw slider 2 709 to slide on the guide rail 707, thereby synchronously driving the sanding frame 703 on the same side to swing in parallel. During the swinging process, the distance between the sanding belts 702 on both sides increases or decreases, thereby achieving sanding of wood surfaces of different sizes.

[0042] See attached Fig.10 To Attachment Fig.12 A stabilizing plate 701 is hinged at the end of the sanding frame 703, an exhaust pipe 710 is fixedly connected to the bottom of the stabilizing plate 701, an air outlet is arranged at one end of the exhaust pipe 710, and the air outlet is connected to an exhaust device, a blocking plate 705 is arranged at the air inlet of the stabilizing plate 701, and an air guide plate 704 is fixedly connected to the other side of the exhaust pipe 710, the end of the air guide plate 704 is located on the plane formed by the axis of the rotating shaft of the end of the sanding frame 703, and there is a gap between the air guide plate 704, the blocking plate 705 and the sanding belt 702.

[0043] Furthermore, an air guide plate is provided between the air guide plate 704 and the blocking plate 705 . The air guide plate and the blocking plate 705 are inclined. The air guide plate 704 and the blocking plate 705 are trumpet-shaped. The constricted openings of the air guide plate 704 and the blocking plate 705 are connected to the exhaust pipe 710 .

[0044] Furthermore, the air guide plate 704 and the sanding belt 702 are horn-shaped, and the wind direction flows from the opening of the air guide plate 704 to the shrinkage.

[0045] Furthermore, the blocking plate 705 is used to block and guide the wood powder adhered to the outer surface of the sanding belt 702 blown by the wind.

[0046] Furthermore, the stabilizing plate 701, the upper surface of the processing table 2, the exhaust pipe 710, and the air guide plate 704 form a working chamber, which can prevent the wood powder from being scattered.

[0047] According to the above structure, by exhausting air at one end of the exhaust pipe 710, the air pressure in the working chamber is reduced. At this time, the outside air is blown at high speed to the wood powder adhered to the outer surface of the sanding belt 702 under the guidance of the air guide plate 704, so that the wood powder is separated from the outer surface of the sanding belt 702, and the sanding belt 702 is cooled at the same time. The blown wood powder is discharged from the air outlet of the exhaust pipe 710 under the blocking and guidance of the blocking plate 705.

[0048] Refer to the attached Fig.13 and attached Fig.14 The ultrasonic detection device 8 includes an electric screw rod 3 801, a clamping plate 802 is fixedly connected to the movable slider of the electric screw rod 3 801, an electric screw rod 4 803 is arranged on one side of the clamping plate 802, an ultrasonic detector 9 is fixedly connected to the movable slider of the electric screw rod 4 803, and the ultrasonic detector 9 is slidably connected to the clamping plate 802.

[0049] A cylinder 804 is provided on one side of the electric screw rod 803, and a blocking angle plate 805 is slidably connected to one side of the clamping plate 802. A spring 2 807 is provided in the clamping plate 802, and the spring 2 807 applies an upward force to the blocking angle plate 805. The blocking angle plate 805 is normally located at the top of the clamping plate 802. The blocking angle plate 805 protrudes from one side of the processing table 2 and is rotatably connected to a rotating wheel 806 and a grinding shaft 808. The rotating wheel 806 and the grinding shaft 808 are connected through a gear set 2 809. A spring 3 810 is provided on one side of the grinding shaft 808, and the spring 3 810 applies a force toward the rotating wheel 806 to the grinding shaft 808.

[0050] According to the above structure, the clamping plate 802 is driven by the electric screw rod 3 801 to clamp the wood surface to ensure that the ultrasonic detector 9 is in contact with the wood surface. Then, under the operation of the cylinder 804, the blocking angle plate 805 is squeezed to contact the top of the wood. At this time, the rotating wheel 806 is in contact with the top of the wood. When the wood moves, it drives the gear set 2 809 to rotate, and finally drives the grinding shaft 808 to grind the top corners of the wood, so as to remove the wood splinters at the top corners of the wood.

[0051] Furthermore, the blocking angle plate 805 is provided with a water retaining plate to prevent the water input by the ultrasonic detector 9 from flowing to the top of the wood, and at the same time to prevent the loss of water flow, which would cause the problem that the ultrasonic wave cannot be transmitted.

[0052] Furthermore, the grinding shaft 808 is ground into a cylindrical frustum, and a scraping blade or scraping particles are provided on the inclined surface.

[0053] Refer to the attached Fig.15 To Attachment Fig.17 The ultrasonic detector 9 includes an ultrasonic detector 901. A liquid outlet 902 and a liquid inlet 903 are provided at the top and bottom of the ultrasonic detector 901. Water flows from the liquid inlet 903 to the liquid outlet 902, and the water flows from bottom to top. Air cleaning parts 908 are provided on both sides of the ultrasonic detector 901, a cavity is provided in the air cleaning part 908, and a partition plate 905 is provided in the cavity, the partition plate 905 divides the cavity into an air inlet channel 906 and a return air channel 907, and one end of the return air channel 907 is connected to the exhaust pipe 904.

[0054] Furthermore, a plurality of water-permeable holes are provided at the cavity position of the ultrasonic sound-emitting part of the ultrasonic detector 901 to avoid the existence of a cavity inside and affect the ultrasonic detection.

[0055] Furthermore, the liquid inlet 903 faces downwards, so as to disperse the impact force of the water flow and prevent the bubbles generated by the water flow from adhering to the wood surface, thereby affecting the detection effect.

[0056] Furthermore, the water outlet of the liquid outlet 902 faces upward, the water flows from bottom to top, and the gas is discharged from the top to avoid gas accumulation.

[0057] Furthermore, one of the ultrasonic detectors 901 is a generator and the other is a receiver, with one end transmitting a signal and the other end receiving a signal, thereby completing the detection of wood.

[0058] Furthermore, the air inlet channel 906 is connected to the air return channel 907, and the connecting end is close to the side of the wood, and there is a constriction in the connecting part to increase the flow rate of the wind.

[0059] According to the above structure, water is delivered through the liquid inlet 903, and the water flows from bottom to top through the liquid outlet 902. At this time, the water is completely filled between the ultrasonic detector 901 and the wood, so that the ultrasonic detector 901 can emit ultrasonic waves to detect the wood. At the same time, under the exhaust of the exhaust pipe 904, the wood powder adhering to the wood surface on the input side can be blown away for the second time, and the water droplets adhering to the wood surface can be blown away at the same time.

[0060] See attached Figure 1 and attached Fig.14 The output end of the processing table 2 is slidably connected with a cutting frame 12, one end of the cutting frame 12 is provided with an inclined surface, and a planing blade is fixedly connected to the inclined surface of the cutting frame 12.

[0061] Furthermore, the cutting frame 12 can be automatically controlled by an electric screw.

[0062] According to the above structure, by manually adjusting the position of the cutting frame 12 and aligning it with the bottom corner of the wood, the wood thorns that are difficult to clean at the corner of the wood can be removed by moving the wood.

[0063] An anti-corrosion oil rod surface detection method based on ultrasonic detection, comprising: S1: Get the position status of the wood on the feeding platform; S2: According to the inclination angle of the wood, adjust the wood clamping part to align with the inclination angle of the wood; S3: According to the inclination angle of the wood and the conveying speed of the wood, the wood clamping parts are controlled to move synchronously to ensure that the wood moves smoothly between the wood clamping parts, and the wood is clamped and guided by the wood clamping parts; S4: The wood is polished on the longitudinal plane of the polished wood under the guidance of the clamping part; S5: Use an ultrasonic detector to fit the polished surface, with one side transmitting and the other side receiving, and at the same time, move the ultrasonic detector up and down periodically; S6: As the wood moves, it is determined whether there are holes inside the wood based on the processing of the signal from the receiving end of the ultrasonic detector; S7: When the geometric center of the wood coincides with the wood clamping part, the wood clamping part is adjusted to rotate, and the wood is rotated to a position flush with the conveying square of the feeding platform; S7: The inspected wood is transported to the discharging table.

[0064] According to the above method, the wood clamping part corresponds to the above clamping and regulating mechanism 6, which adopts linear clamping, and the clamping surface is in rolling contact, which can facilitate the transportation of wood and guide the wood at the same time; The wood clamping part in the method moves synchronously, and the reciprocating mechanism 3 drives the clamping and regulating mechanism 6 to slide on the working frame 1 to avoid collision between the wood and the clamping and regulating mechanism 6 when they come into contact; The ultrasonic detector is fitted with the polished surface of the wood through the electric screw three 801 on the ultrasonic detection device 8, and the electric screw three 801 drives the ultrasonic detector to move periodically.

[0065] The working principle of the present invention is as follows: the end position of the wood is collected by the graphic acquisition device, and the position of the processing table 2 is adjusted by the reciprocating mechanism 3. When the position detector 10 detects the wood, the electric screw 601 drives the clamping frame 605 and the clamping roller 606 to clamp the two sides of the wood. When the clamping roller 606 contacts the wood, the steering roller 603 rotates a certain angle under the support of the end of the wood. When the angle sensor 608 detects the rotation angle, the data is synchronized to the turning table 4, and through the operation of the turning table 4, the gap between the two clamping rollers 606 is at a relatively minimum value. At this time, the center line of the rod material and the processing table 2 is horizontal. At the same time, if the clamping frame 605 on one side contacts the outer surface of the wood first, the pressure value measured by the clamping frame 605 on this side is greater than that on the other side. According to the positive and negative values ​​of the difference, the moving direction of the reciprocating mechanism 3 is controlled until the difference is within a suitable range, so that the grinding device 7 can clamp the two sides of the wood. The electric screw rod 708 drives the screw rod slider 709 to slide on the guide rail 707, thereby synchronously driving the sanding frame 703 on the same side to swing in parallel. When the sanding frame 703 comes into contact with the surface of the wood, both sides of the wood are sanded as the wood is transported; When the position detector 2 11 detects wood, the electric screw 3 801 drives the clamping plate 802 to clamp the wood surface, and makes the ultrasonic detector 9 fit the wood surface. Under the reciprocating rotation of the electric screw 4 803 and the transportation of the wood, the wormholes inside and outside the wood are detected.

[0066] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
