Description

Technical Field

[0001] The present application relates to the technical field of workpiece quality detection, and in particular to a fully automatic eddy current flaw detection hardness detection device. Background Art

[0002] Eddy current flaw detection is a detection device that does not require direct contact with the workpiece. The product to be inspected enters the flaw detection station along a linear guide rail, and a current is applied to the excitation coil to form an eddy current magnetic field. The excitation coil establishes an alternating magnetic field. The alternating magnetic field passes through the product to be inspected and has electromagnetic induction with it, establishing eddy currents inside the product to be inspected. The eddy currents in the product to be inspected will also generate their own magnetic fields. The effect of the eddy current magnetic field changes the strength of the original magnetic field, which in turn causes changes in the coil voltage and impedance. When defects appear on the surface or near the surface of the conductor, it will affect the intensity and distribution of the eddy current. The change in the eddy current will cause changes in the voltage and impedance of the detection coil. Based on this change, it can be indirectly known whether the workpiece has defects such as cracks and sand spots.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0036] The inventor of the present application has found that the eddy current flaw detection and hardness testing device in the prior art can collect defective products but cannot classify different defective products. Secondary sorting is required when the defective products are subsequently processed. Therefore, the present application mainly adopts the following scheme: Reference Figure 1The fully automatic eddy current flaw detection hardness detection device provided in the embodiment of the present application includes a detection frame 1. The detection frame 1 is a rectangular frame structure, made of high-strength aluminum alloy material, and has good corrosion resistance and stability. On this basis, the detection frame 1 in this embodiment is also added with reinforcing ribs, which are L-shaped steels welded at the four corners of the detection frame 1, thereby enhancing the overall rigidity and stability of the detection frame 1. A workpiece conveyor belt 11 and a recovery conveyor belt 12 are arranged on the top of the detection frame 1, and a hardness detector 13 and an eddy current flaw detection detector 14 are arranged in sequence along the workpiece conveyor belt 11. The hardness detector 13 and the eddy current flaw detection detector 14 are both arranged above the workpiece conveyor belt 11 through a bracket to successively detect the workpiece. In addition, the detection frame 1 is also provided with a defective product sorting machine 2 between the workpiece conveyor belt 11 and the recovery conveyor belt 12. In this embodiment, the defective product sorting machine 2 is set as two, which are respectively located on the sides of the hardness detector 13 and the eddy current flaw detection detector 14 to transport two different defective products to the recovery conveyor belt 12 respectively.

[0037] Reference Figure 1 The workpiece conveyor belt 11 is a belt conveyor belt, and the belt surface is provided with anti-skid patterns to ensure that the workpiece does not slip during the conveying process. The hardness detector 13 is an ultrasonic hardness tester, which measures the hardness value of the workpiece by emitting ultrasonic signals and receiving reflected signals. The eddy current flaw detector 14 is an eddy current sensor, which generates an alternating magnetic field and generates eddy currents in the workpiece to detect surface defects of the workpiece.

[0038] Reference Figure 1 and Figure 2 The recycling conveyor belt 12 is a chain conveyor belt, which is composed of a plurality of chain links. Each chain link is provided with a support block 3. The support block 3 is made of wear-resistant plastic and has good self-lubrication and low friction coefficient. The support block 3 is provided with a lower conveying trough 31 and an upper conveying trough 32. The lower conveying trough 31 is located above the lower conveying trough 31 and is connected. From the cross-section, the lower conveying trough 31 and the upper conveying trough 32 form a stepped trough. The width of the upper conveying trough 32 is greater than that of the lower conveying trough 31. In actual practical use, the upper conveying trough 32 and the lower conveying trough 31 are respectively used to place different types of defective products. This embodiment takes a square workpiece as an example. For example, when the hardness detector 13 detects that the workpiece below it is a defective product, the defective product can be used. The sorting machine 2 places the workpiece in a horizontal state in the lower conveying trough 31. When the eddy current flaw detector 14 detects that the workpiece below it is a defective product, the defective product sorting machine 2 can be used to place the workpiece in a vertical state in the upper conveying trough 32. By placing the square workpiece in different ways to stably place it in the lower conveying trough 31 and the upper conveying trough 32, different types of defective products can be placed together on the recovery conveyor belt 12, and finally various types of defective products can be transported backward along the recovery conveyor belt 12, which has higher production efficiency.

[0039] Reference Figure 1 and Figure 3 The defective product sorting machine 2 includes a rotating base 21, a lifting drive 22, a telescopic drive 23 and a clamp 25. The rotating base 21 is rotatably connected to the detection frame 1 through a bearing and can rotate freely in a horizontal plane. The lifting drive 22 is a cylinder and is connected to the top of the rotating base 21. It is driven by air pressure to achieve lifting in the vertical direction. The telescopic drive 23 is an electric push rod and is connected to the top of the lifting drive 22. The clamp 25 is rotatably connected to the end of the telescopic drive 23 through an angle adjustment drive 24. The angle adjustment drive 24 is a motor, which has achieved the rotation of the clamp 25.

[0040] Reference Figure 3 Specifically, the clamping jaw 25 includes a mounting plate 251, a clamping plate 252, a clamping driver 253 and a clamping elastic member 254. The mounting plate 251 is rotatably connected to the end of the telescopic driver 23 and the angle adjustment driver 24 actually controls the rotation of the mounting plate 251. There are two clamping plates 252 and they are respectively located on both sides of the mounting plate 251. The clamping driver 253 is a pneumatic cylinder, which drives the two clamping plates 252 to open and close by air pressure. The clamping elastic member 254 is a spring and is arranged between the mounting plate 251 and the clamping plate 252 to increase the clamping force. On this basis, the clamping jaw 25 in this embodiment is also added with a clamping feedback device, which includes a pressure sensor and a controller arranged on the clamping plate 252. The pressure sensor is used to monitor the clamping force of the clamping plate 252 on the workpiece in real time and transmit the data to the controller. The controller automatically adjusts the air pressure of the pneumatic cylinder according to the data of the pressure sensor to ensure that the clamping force is always in the best state, and avoids the damage or falling off of defective products due to excessive or insufficient clamping force.

[0041] In addition, the gripper 25 is also equipped with a visual positioning system, which includes a camera and an image processing module. The camera is installed at the front end of the gripper 25 to capture images of defective products, and the image processing module is used to analyze image data and determine the precise position of defective products. According to the results of the image processing module, the controller controls the telescopic drive 23 and the angle adjustment drive 24 to enable the gripper 25 to accurately clamp defective products. With the assistance of the visual positioning system, the accuracy and efficiency of defective product sorting can be improved. The gripper 25 of the defective product sorting machine 2 determines the precise position of defective products through the visual positioning system, and ensures the appropriateness of the clamping force through the clamping feedback device, thereby ensuring the safe and reliable transfer of defective products. In this way, not only the instant classification of defective products is achieved, but also the accuracy and reliability of defective product sorting are improved, further improving production efficiency and product quality control capabilities.

[0042] Reference Figure 4 and Figure 5A material box 4 is provided at the bottom of the detection rack 1. The material box 4 is a rectangular box-shaped structure with an opening at the top. It is made of stainless steel and has good corrosion resistance and sealing properties. An upper recycling area 41, a lower recycling area 42 and a good product recycling area 43 are provided inside the material box 4. The upper recycling area 41 and the lower recycling area 42 are respectively used to store different types of defective products, and the good product recycling area 43 is used to store qualified products. An upper recycling port 410 is provided on the side wall of the upper recycling area 41. An inner slide 411 is provided at the upper recycling port 410. The top of the inner slide 411 is located between the lower conveying trough 31 and the upper conveying trough 32, and is used to guide the defective products in the lower conveying trough 31 into the upper recycling port 410. The lower recycling area 42 is provided with a lower recycling port 420, and an outer slide plate 421 is provided at the lower recycling port 420. The top of the outer slide plate 421 is located above the upper conveying trough 32, and is used to guide the defective products in the upper conveying trough 32 into the lower recycling port 420. The side wall of the good product recycling area 43 is provided with a good product recycling port 430, and a good product slide plate 431 is provided at the good product recycling port 430. The top of the good product slide plate 431 is located above the workpiece conveyor belt 11, and is used to guide the good products into the good product recycling port 430.

[0043] Reference Figure 6 , a vertical plate 44 is arranged inside the material box 4, one side of the vertical plate 44 forms a good product recovery area 43, and the other side is separated by a horizontal plate 45 connected to the vertical plate 44 to form an upper recovery area 41 and a lower recovery area 42. The vertical plate 44 and the inner wall of the material box 4 are slidably connected by a slider slot, and the volume of each recovery area can be changed by manually adjusting the position of the vertical plate 44. In addition, a locking assembly 441 for locking the position of the vertical plate 44 is arranged inside the material box 4, and the locking assembly 441 uses a bolt to tighten the vertical plate 44 to achieve the locking of the vertical plate 44 at any position. In actual application scenarios, a scale ruler can also be set on the top of the side wall of the material box 4 to indicate the position of the vertical plate 44, so that the operator can adjust the volume of each recovery area more intuitively and quickly. The side wall of the material box 4 is provided with a clearance hole 450 for the horizontal plate 45 to pass through and slide. When the vertical plate 44 is adjusted, the horizontal plate 45 can go deep into or out of the material box 4 to make adaptive changes.

[0044] Reference Figure 6The horizontal plate 45 includes a plurality of horizontal bars 451 and connecting ropes 452 are arranged between adjacent horizontal bars 451, so that the horizontal plate 45 can be bent, so that the part of the horizontal plate 45 located outside the material box 4 can naturally droop and fit the outer wall of the material box 4, so as to reduce the excessive occupation of the horizontal space outside the material box 4. In addition, the inner wall of the material box 4 is also provided with a support groove 453 for the end of the horizontal bar 451 to enter and slide freely. The two ends of the horizontal bar 451 slide stably in the corresponding support groove 453 and are stably supported. The plurality of horizontal bars 451 located in the material box 4 can achieve stable support for defective products under the stable support of the support groove 453, so that the overall stability of the device is higher.

[0045] Reference Figure 7 A limit assembly 454 is also provided on the outside of the material box 4 for limiting any cross bar 451 from entering the interior of the material box 4. The limit assembly 454 includes a lever slidably connected to the material box 4. The lever is located above the clearance hole 450 and is slidably connected to the outer wall of the material box 4 through a slide groove. Under normal conditions, the lever can slide downward under the action of its own gravity and be inserted between the two cross bars 451, and the bottom of the lever is against the inner wall of the clearance hole 450. In this state, the cross bars 451 outside the material box 4 can be limited from continuing to enter the interior of the material box 4, thereby maintaining the stability of the relative position relationship between the cross bars 451.

[0046] The implementation principle of this embodiment is as follows: the workpiece is transported to the inspection station through the workpiece conveyor belt 11, and is inspected by the hardness detector 13 and the eddy current flaw detector 14 in turn. If the workpiece passes both inspection results, it will eventually enter the good product recovery area 43 through the good product slide 431; if the workpiece inspection result is unqualified, it will be transferred to the corresponding lower conveying trough 31 or upper conveying trough 32 through the defective product sorting machine 2 at the corresponding position. Finally, the defective products in the lower conveying trough 31 enter the upper recovery area 41 through the inner slide 411, and the defective products in the upper conveying trough 32 enter the lower recovery area 42 through the outer slide 421. In addition, through the design of reinforcing ribs and shock-absorbing feet, the overall rigidity and stability of the inspection frame 1 can be effectively enhanced, the noise and vibration during the operation of the equipment can be reduced, and the stability and durability of the entire device can be improved. In summary, the present application not only realizes the instant classification of defective products, but also improves the stability and durability of the entire device, and further improves production efficiency.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
