Description

Technical Field

[0001] The present invention relates to the technical field of product defect detection, and in particular to a method and device for detecting defects in irradiation processing. Background Art

[0002] The defect detection on the surface of tungsten copper film is generally carried out by industrial cameras. The industrial cameras can accurately detect the surface defects of tungsten copper film through high-precision image capture and processing capabilities, thereby ensuring product quality and production efficiency. After the defects are detected, the surface of the tungsten copper film must be irradiated. The main purpose of irradiation processing of tungsten copper film is to improve hardness and strength (irradiation processing may cause the atoms in the tungsten copper film to rearrange or produce new phase structures, thereby improving its hardness and strength. The mechanical properties of the material can be optimized through irradiation-induced microstructural changes.) and improve radiation resistance (tungsten copper film may show better radiation resistance after specific irradiation treatment. For example, through neutron irradiation or ion irradiation, the behavior of the material in an irradiated environment can be studied, and its radiation resistance can be optimized accordingly).

[0003] Since the tungsten copper film is rolled up on an I-shaped winding drum, the I-shaped winding drum needs to be clamped and installed during the defect detection process. After clamping, it is also necessary to ensure that the I-shaped winding drum can be easily rotated to release the tungsten copper film thereon (the tungsten copper film needs to be gradually moved backwards for defect detection). After the detection is completed, the I-shaped winding drum needs to be released. However, it is difficult for ordinary clamping devices to quickly install and release the I-shaped winding drum. Once the I-shaped winding drum is installed, it is also difficult to make the I-shaped winding drum easily rotate to release the tungsten copper film thereon. For this reason, we have introduced a method and device for irradiation processing defect detection. Summary of the invention

[0021] The present invention also provides a detection method of the irradiation processing defect detection device, which specifically comprises the following steps:

[0022] S1. Place the front I-shaped take-up drum on two sets of arc seats, pass the tungsten copper film on the front I-shaped take-up drum through the horizontal frame, the detection shell and the irradiation chamber, and then reel it onto the rear I-shaped take-up drum;

[0023] S2. The front I-shaped winding drum is clamped by a clamping and lifting mechanism.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example:

[0046] See also Figure 1-15 , the present invention provides a technical solution:

[0047] A device for detecting defects in irradiation processing, comprising a support 1, wherein an arc-shaped seat 15 for placing a front I-shaped winding drum 35 is provided on the inner side of the front end of the support 1, and a clamping and lifting mechanism, a horizontal frame 9, a detection housing 2, an irradiation chamber 3 and a rear I-shaped winding drum 5 are provided on the upper end of the support 1 in sequence from front to back;

[0048] The clamping and lifting mechanism includes a stand 16 fixed at the top of the front end of the bracket 1, a T-shaped lifting seat 26 slidingly connected in the cross groove 31 inside the stand 16, a rotating frame movably connected to the outside of the lower part of the stand 16 by two sets of connecting plates 17, a supporting wheel 29 movably connected after the inner side end of the rotating frame extends into the cross groove 31, and a sliding shell 21 slidingly connected to the outside of the bracket 1;

[0049] The rotating frame includes a rotating drum 33 movably connected between two sets of connecting plates 17 by a rotating shaft 22 , a U-shaped seat 32 provided inside the rotating drum 33 for movably mounting the abutting wheel 29 , and an abutting plate 23 provided outside the rotating drum 33 .

[0050] A lifting frame 20 is connected to the middle of the sliding shell 21, and a support block 24 is connected to the bottom of the lifting frame 20 through an inclined plate 25 inclined outward;

[0051] The T-shaped lifting seat 26 is located on the top of the abutment wheel 29;

[0052] A moving rod 34 passes through the middle of the T-shaped lifting seat 26, and the inner end of the moving rod 34 is connected to a plug connector 30 for inserting into the central hole 37 in the middle of the front I-shaped winding drum 35. The outer end of the moving rod 34 is sleeved with the spring 27 and fixed with a semicircular abutment head 28.

[0053] like Figure 3 , 4 In the initial state shown in FIGS. 6, 8, 9 and 10, under the elastic force of the spring 27 on the semicircular abutment head 28, the moving rod 34 moves toward the outside of the T-shaped lifting seat 26, so that the semicircular abutment head 28 is located on the inner side of the corresponding abutment block 24, and the plug connector 30 is close to the inner wall of the T-shaped lifting seat 26;

[0054] At the same time, the abutment block 24 is located directly above the corresponding abutment plate 23, and the two are not in contact yet.

[0055] A horizontal plate 19 is provided in the center of the rear end of the top of the lifting frame 20 , and an electric cylinder 8 is installed in the center of the top of the cross frame 9 . The piston rod at the output end of the electric cylinder 8 passes through the cross frame 9 and is connected to the top of the horizontal plate 19 .

[0056] The electric cylinder 8 is controlled by PLC. The electric cylinder 8 adopts Festo small slide cylinder: model 170500SLS-16-20-PA or British Kennetrol vane rotary cylinder: model 094-100 or German AVENTICS diaphragm and piston cylinder: model 5218555110 or other models that meet the use requirements.

[0057] The piston rod of the electric cylinder 8 extends, so that the horizontal plate 19 drives the lifting frame 20 to move downward. At this time, the inclined plate 25 and the abutment block 24 also move downward synchronously, and the semicircular abutment head 28 moves upward relative to the inclined plate 25. The inner wall of the inclined plate 25 abuts against the semicircular abutment head 28. The semicircular abutment head 28 squeezes the spring 27 in a compressed state, so that the semicircular abutment head 28 pushes the moving rod 34 to move toward the inside of the T-shaped lifting seat 26 until the plug connector 30 is pushed into the center hole 37 in the middle of the front I-shaped winding drum 35 (as shown in FIG. Fig.11 and 12 shown);

[0058] At this time, the abutment block 24 just moves to the upper end surface of the abutment plate 23;

[0059] The piston rod of the electric cylinder 8 continues to extend, and the semicircular abutment head 28 moves to the inner wall of the bottom of the lifting frame 20, so that the plug connector 30 is further inserted into the central hole 37. At the same time, the abutment block 24 presses down the abutment plate 23, so that the abutment plate 23, the rotating cylinder 33 and the U-shaped seat 32 rotate as a whole with the rotating shaft 22 as the center, so that the abutment wheel 29 moves upward;

[0060] At this time, the abutment wheel 29 pushes the T-shaped lifting seat 26 upward along the cross groove 31, so that the T-shaped lifting seat 26 drives the semicircular abutment head 28, the spring 27, the moving rod 34 and the plug connector 30 to move upward as a whole. Since the plug connector 30 has been inserted into the center hole 37, when the semicircular abutment head 28, the spring 27, the moving rod 34 and the plug connector 30 move upward as a whole, the front I-shaped winding drum 35 is lifted until the bottom of the front I-shaped winding drum 35 leaves the arc seat 15 (such as Fig.13 and 14 shown);

[0061] Since the bottom of the front I-shaped winding drum 35 leaves the arc seat 15, the two are no longer in contact and no friction is generated, so that the rear I-shaped winding drum 5 can smoothly wind up the tungsten copper film 36, and when the rear I-shaped winding drum 5 is winding up the tungsten copper film 36, the front I-shaped winding drum 35 rotates to release the tungsten copper film 36, so that the tungsten copper film 36 passes backward through the cross frame 9, the detection shell 2 and the irradiation chamber 3 in sequence.

[0062] The tungsten copper film 36 on the front I-shaped winding drum 35 passes through the cross frame 9, the detection housing 2 and the irradiation chamber 3 and is then wound up on the rear I-shaped winding drum 5;

[0063] The front and rear ends of the irradiation chamber 3 are both provided with upper and lower sets of support guide wheels 6, and the tungsten copper film 36 passes between the upper and lower sets of support guide wheels 6. Such an arrangement can ensure that the tungsten copper film 36 passes through the irradiation chamber 3 horizontally.

[0064] The rear I-shaped take-up drum 5 is movably connected between the vertical plates 4 at the upper end of the rear part of the bracket 1, and a first motor 18 for driving the rear I-shaped take-up drum 5 to rotate is also installed on the vertical plate 4 on one side.

[0065] The first motor 18 is controlled by PLC, and the model of the first motor 18 is Mitsubishi HC-SF202B motor, Mitsubishi HG-SR702B motor, Mitsubishi HK-KT7M3UWBJ or other models that meet the use requirements.

[0066] The first motor 18 works to drive the rear I-shaped winding drum 5 to rotate, so that the rear I-shaped winding drum 5 can wind up the tungsten copper film 36 .

[0067] The clamping and lifting mechanism clamps the front I-shaped winding drum 35 and lifts the front I-shaped winding drum 35 away from the arc seat 15. As the rear I-shaped winding drum 5 winds up the tungsten copper film 36, the front I-shaped winding drum 35 rotates to release the tungsten copper film 36.

[0068] A cleaning mechanism is provided at the front end of the horizontal frame 9 for cleaning the upper and lower end surfaces of the tungsten copper film 36;

[0069] The cleaning mechanism includes two sets of upper and lower U-shaped frames 38 provided at the front end of the horizontal frame 9, an upper cleaning roller 12 movably connected in the upper U-shaped frame 38, and a lower cleaning roller 13 movably connected in the lower U-shaped frame 38;

[0070] A second motor 14 for driving the upper cleaning roller 12 is also provided on the side of the upper U-shaped frame 38;

[0071] One end of the upper cleaning roller 12 and the lower cleaning roller 13 extend out of the corresponding U-shaped frame 38 and are respectively connected to the upper gear 10 and the lower gear 11, and the upper gear 10 and the lower gear 11 are meshed with each other;

[0072] The upper cleaning roller 12 and the lower cleaning roller 13 are respectively in close contact with the upper and lower end surfaces of the tungsten copper film 36 .

[0073] The second motor 14 is controlled by PLC, and the model of the second motor 14 is Mitsubishi HC-SF202B motor, Mitsubishi HG-SR702B motor, Mitsubishi HK-KT7M3UWBJ or other models that meet the use requirements.

[0074] The second motor 14 works to drive the upper cleaning roller 12 to rotate. Since the upper gear 10 and the lower gear 11 are meshed with each other, the lower cleaning roller 13 is also rotated. The upper cleaning roller 12 and the lower cleaning roller 13 clean the upper and lower end surfaces of the tungsten copper film 36 respectively to remove dust particles or water stains and other debris on the upper and lower end surfaces of the tungsten copper film 36, so that the subsequent industrial camera 7 can clearly take pictures of the upper and lower end surfaces of the tungsten copper film 36;

[0075] After the tungsten copper film 36 is moved backward (eg Fig.15 When the upper cleaning roller 12 and the lower cleaning roller 13 rotate simultaneously, the cleaning effect on the upper and lower end surfaces of the tungsten copper film 36 can be improved.

[0076] An industrial camera 7 for photographing the upper and lower surfaces of the tungsten copper film 36 is provided inside the detection shell 2. The industrial camera 7 is controlled by PLC and is a Fangte Technology FT-U3630C USB3.0 industrial camera, A30 Series smart camera or other models that meet the usage requirements.

[0077] The irradiation chamber 3 is provided with an irradiation device for irradiating the upper and lower end surfaces of the tungsten copper film 36;

[0078] After taking the photos, use a computer to compare the photos to find out the defects in the photos;

[0079] The irradiation device irradiates the upper and lower end surfaces of the tungsten copper film 36;

[0080] The irradiation device is a γ irradiation device (such as the RP6000 nuclear radiation detector, the JB4040 intelligent β, γ surface contamination detector) or an electron beam irradiation device or an X-ray irradiation device (such as the X-RAD225 X-ray irradiator, the JUNCE JV6000 radiation survey instrument) or other irradiation devices that meet the use requirements.

[0081] After irradiation treatment:

[0082] 1. Improve the hardness and strength of tungsten copper film 36:

[0083] The irradiation process may cause the atoms in the tungsten copper film 36 to rearrange or generate a new phase structure, thereby improving its hardness and strength.

[0084] The mechanical properties of materials can be optimized through irradiation-induced microstructural changes.

[0085] 2. Improve radiation resistance:

[0086] The tungsten copper film 36 may exhibit better radiation resistance after being subjected to specific radiation treatment.

[0087] For example, through neutron irradiation or ion irradiation, the behavior of materials in irradiation environments can be studied and their radiation resistance can be optimized accordingly.

[0088] After the rear I-shaped winding drum 5 has finished winding up the tungsten copper film 36 , the clamping and lifting mechanism places the front I-shaped winding drum 35 on the arc seat 15 , and releases the clamping of the front I-shaped winding drum 35 at the same time.

[0089] That is, the piston rod of the electric cylinder 8 retracts, so that the horizontal plate 19 drives the lifting frame 20 to move upward. At this time, the inclined plate 25 and the abutting block 24 also move upward synchronously, and the semicircular abutting head 28 moves downward relative to the inclined plate 25. After the semicircular abutting head 28 gradually moves upward, under the pressure of the T-shaped lifting seat 26 on the abutting wheel 29, the abutting plate 23, the rotating drum 33 and the U-shaped seat 32 rotate as a whole with the rotating shaft 22 as the center, until the abutting wheel 29 moves down to the bottom of the cross groove 31 to form a reset;

[0090] At this time, the T-shaped lifting seat 26 will move down along the cross groove 31 to reset;

[0091] Under the elastic force of the spring 27 on the semicircular abutment head 28, the semicircular abutment head 28 moves along the inner wall of the inclined plate 25 to the inner wall position of the abutment block 24, so that the semicircular abutment head 28 pulls the plug connector 30 out of the center hole 37 through the moving rod 34;

[0092] Finally, after the T-shaped lifting seat 26 drives the semicircular abutment head 28, the spring 27, the moving rod 34 and the plug connector 30 to move downward and reset as a whole, the bottom of the front I-shaped winding drum 35 is seated on the arc seat 15, thereby releasing the front I-shaped winding drum 35.

[0093] The present invention also provides a detection method of the irradiation processing defect detection device, which specifically comprises the following steps:

[0094] S1, placing the front I-shaped take-up drum 35 on the two sets of arc seats 15, passing the tungsten copper film 36 on the front I-shaped take-up drum 35 through the cross frame 9, the detection housing 2 and the irradiation chamber 3, and then reeling it onto the rear I-shaped take-up drum 5;

[0095] S2, the front I-shaped winding drum 35 is clamped by a clamping and lifting mechanism. At the same time, the clamping and lifting mechanism lifts the front I-shaped winding drum 35 away from the arc seat 15, and the rear I-shaped winding drum 5 winds up the tungsten copper film 36, and the front I-shaped winding drum 35 rotates to release the tungsten copper film 36;

[0096] S3, the cleaning mechanism cleans the upper and lower end surfaces of the tungsten copper film 36, the industrial camera 7 takes pictures of the upper and lower end surfaces of the tungsten copper film 36, and the irradiation device irradiates the upper and lower end surfaces of the tungsten copper film 36;

[0097] S4, after the rear I-shaped winding drum 5 has finished winding up the tungsten copper film 36, the clamping and lifting mechanism places the front I-shaped winding drum 35 on the arc seat 15, and releases the clamping of the front I-shaped winding drum 35 at the same time.

[0098] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
