[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] The electron beam welding method can be used to continuously weld the metal strip resistors in the moving process, thus meeting the requirements for continuous production and manufacturing of the metal strip resistors.

[0031] During the electron beam welding process, it will also produce some unique defects, such as nail tip protrusion defects on the outer surface, cracks and pores inside; these defects seriously affect the quality of metal strip resistors, so it is necessary to perform welding inspection on metal welding strips.

[0032] By installing image detection mechanisms on both sides of the metal strip resistor, continuous image detection can be performed on both sides of the metal strip resistor, and defects on the surface of the metal strip resistor can be discovered and recorded in time.

[0033] The defects inside the metal strip resistor cannot be directly observed through the image detection structure, and ultrasonic detection equipment is needed to detect and analyze the inside of the metal strip resistor. In order to reduce the influence of the coupling agent on image detection, most of the existing ultrasonic detection equipment is installed separately at a position far behind the image detection mechanism, resulting in discontinuous detection and a large footprint. In addition, some top defects or some raised obstacles on the surface of the metal strip resistor will have a certain impact on the surface of the ultrasonic detection equipment during the movement process, affecting the normal detection of the ultrasonic detection equipment.

[0034] For relevant patent literature, please refer to our company’s prior applications: A metal electron beam welding defect detection method and system (CN117576086B), An electron beam welding detection device for metal strip resistors (application number: 202422150011X).

[0035] In order to solve the above problems, refer to the attached Figure 1 -Attached Fig.10 , an electron beam welded parts inspection device, used for inspecting a metal strip resistor 500, the metal strip resistor 500 includes two electrode strips 510 and a resistor unit 520 located between the two electrode strips 510, and the two electrode strips 510 and the resistor unit 520 can be continuously welded by an electron beam welding device to form a strip-shaped metal strip resistor 500; the welding and fixing are completed during the synchronous movement of the two electrode strips 510 and the resistor unit 520.

[0036] The electron beam welded parts inspection device includes a first image detection mechanism 200 for performing image detection on the first side surface of the metal strip resistor 500 and a second image detection mechanism 400 for performing image detection on the second side surface of the metal strip resistor 500. The first image detection mechanism 200 and the second image detection mechanism 400 are located at two intervals and can perform image detection on both sides of the metal strip resistor 500. The above-mentioned image detection mechanism can be selected as an existing image detection device, and technicians in this field can make adaptive selections as needed.

[0037] An ultrasonic detection mechanism 300 is installed between the first image detection mechanism 200 and the second image detection mechanism 400. The ultrasonic detection mechanism 300 performs continuous ultrasonic detection on the metal strip resistor 500. The ultrasonic detection method can detect and record the defects inside the metal strip resistor 500. By combining the ultrasonic detection and image detection methods, the defects on the surface and inside of the metal strip resistor 500 can be efficiently and continuously detected, thereby improving the effect of defect detection of the metal strip resistor 500.

[0038] Specifically, the ultrasonic detection mechanism 300 includes an ultrasonic detection mounting frame 310, inside which are sequentially installed a surface cleaning device 320 and an ultrasonic detection assembly 330 located on the first side of the metal strip resistor 500; the surface cleaning device 320 continuously operates to continuously clean the surface of the first side of the metal strip resistor 500, and can remove some of the sharp spike protrusions on the surface of the first side of the metal strip resistor 500, thereby ensuring the flatness of the surface of the metal strip resistor 500 and ensuring the continuity and stability of the ultrasonic detection of the ultrasonic detection assembly 330.

[0039] The ultrasonic detection component 330 includes an ultrasonic detector 332 located on the first side of the metal strip resistor 500 and a second support roller 331 located on the second side of the metal strip resistor 500. The second support roller 331 can be located on the second side to support and limit the metal strip resistor 500, thereby ensuring that the ultrasonic detector 332 and the surface of the metal strip resistor 500 are tightly and stably attached. The ultrasonic detector 332 is used to continuously apply coupling agent and ultrasonic detection to the first side surface of the metal strip resistor 500. The coupling agent is applied at the detection position, which can reduce the friction between the metal strip resistor 500 and the ultrasonic detector 332 while reducing the air gap between the two, thereby improving the accuracy of ultrasonic detection.

[0040] In summary, through the above-mentioned structural design, the ultrasonic detection mechanism 300 can be arranged between the first image detection mechanism 200 and the second image detection mechanism 400. In the process of image detection of the surfaces on both sides of the metal strip resistor 500, the ultrasonic detection of the inside of the metal strip resistor 500 can be performed on the first side of the metal strip resistor 500. The multiple groups of detection mechanisms are compactly arranged to ensure the continuous detection and reduce the space occupied by the equipment; at the same time, by installing a surface cleaning device 320 on the front side of the ultrasonic detection component 330, the defects on the surface of the metal strip resistor 500 can be efficiently processed, ensuring the smoothness and continuity of the surface of the metal strip resistor 500, and ensuring the continuous and stable subsequent ultrasonic detection; through the above-mentioned method, the surface of the metal strip resistor 500 can be continuously and efficiently detected by image and ultrasonic, which greatly improves the efficiency of the surface detection of the metal strip resistor 500.

[0041] Specifically, the first image detection mechanism 200 includes an image detection component 210, a background light source 220 and two conveying roller groups 230, the two conveying roller groups 230 are inclined toward a first direction, thereby controlling the metal strip resistor 500 to be in an inclined posture for continuous conveyance.

[0042] Through the above-mentioned structural design, the metal strip resistor 500 can be controlled to be in a tilted posture for image detection of the first side surface, and at the same time, the metal strip resistor 500 can be controlled to be in a tilted posture for ultrasonic detection. The raised obstacles cleaned by the surface cleaning device 320 can move downward along the tilted surface of the metal strip resistor 500, so as to facilitate the timely removal of the raised obstacles, further ensuring the continuity and stability of the ultrasonic detection process, and also ensuring the smoothness and stability of the metal strip resistor 500 during the subsequent transportation process.

[0043] It should be noted that the structure of the second image detection mechanism 400 here is opposite to the first image detection mechanism 200, except that the positions of the image detection component 210 and the background light source 220 are opposite, so that image detection of different sides of the metal strip resistor 500 can be realized; at the same time, the second image detection mechanism 400 here can also be set to an inclined structure, and the first image detection mechanism 200 and the second image detection mechanism 400 are located on both sides to play a guiding role, ensuring that the metal strip resistor 500 in the middle section between the two is in a continuous and flat state, thereby realizing efficient, stable and continuous ultrasonic detection.

[0044] The conveying roller set 230 here includes a conveying shaft 231 , on the surface of which two conveying roller bodies 232 are installed at intervals. A through notch 233 is formed between the two conveying roller bodies 232 to allow the resistor unit 520 to pass through for normal conveyance.

[0045] The image detection assembly 210 here includes an image detection mounting frame 211 and an image detection element 212. The image detection element 212 can actually detect and record the defects on the surface of the metal strip resistor 500.

[0046] Here, the first image detection mechanism 200, the second image detection mechanism 400 and the ultrasonic detection mechanism 300 are positioned and fixed by the supporting device 100, the first image detection mechanism 200 and the second image detection mechanism 400 on both sides are fixed by the supporting frame 110, and the ultrasonic detection mechanism 300 located in the middle is positioned and fixed by the supporting platform 120.

[0047] A coupling agent collecting device 340 is also provided inside the ultrasonic detection mechanism 300 . The coupling agent collecting device 340 is located on the side of the ultrasonic detection component 330 away from the surface cleaning device 320 . The coupling agent coated on the first side surface of the metal strip resistor 500 is collected by the coupling agent collecting device 340 and pumped to the side of the ultrasonic detection component 330 .

[0048] By setting the above structure, the excess coupling agent on the first side of the surface of the metal strip resistor 500 can be collected and re-pumped to the side of the ultrasonic detection component 330 for recycling; the coupling agent collection device 340 is located behind the metal strip resistor 500 conveying line and will not affect the ultrasonic detection of the ultrasonic detection component 330.

[0049] Specifically, the coupling agent collecting device 340 includes a third supporting roller 341 located on the second side of the metal strip resistor 500 and a coupling agent collecting component 342 located on the first side of the metal strip resistor 500. The coupling agent collecting component 342 collects and pumps the coupling agent to the side of the ultrasonic detection component 330. The third supporting roller 341 can be located on the second side to support the metal strip resistor 500, ensuring that the strip-shaped metal strip resistor 500 is in a relatively stable state. In addition, the coupling agent collecting component 342 can be located on the first side to continuously intercept and collect the coupling agent, ensuring continuous and stable collection of the coupling agent.

[0050] A pumping device 350 is installed on the outside of the third support roller 341. The first end of the pumping device 350 is connected to the coupling agent collecting assembly 342, and the second end of the pumping device 350 is connected to the ultrasonic detector 332. The unidirectional pumping of the coupling agent is completed by the pumping device 350. The pumping device 350 here can be designed to be linked with the third support roller 341. The coupling agent is pumped during the continuous rotation of the third support roller 341, thereby realizing automatic control and reducing the difficulty of control.

[0051] The pumping device 350 here can be selected as a combination structure of a cam and an elastic airbag. The cam here is fixed to the third support roller 341. When the third support roller 341 drives the cam to rotate continuously, the elastic airbag can be squeezed periodically. The elastic airbag here is connected to a pipeline with two built-in one-way valves. Under the action of the two sets of one-way valves, one-way pumping control of the coupling agent is achieved; and as the delivery rate of the metal strip resistor 500 increases, the amount of pumped coupling agent increases accordingly, thereby achieving adaptive adjustment.

[0052] The pumping device 350 can also be selected as an existing flow pump, which is electrically connected to the third support roller 341 for control, so as to realize unidirectional quantitative pumping control of the coupling agent.

[0053] Please refer to the attached Fig.10 Specifically, the coupling agent collecting assembly 342 includes a collecting plate 3422 with a bending design, the upper end of the collecting plate 3422 is fixedly connected to the ultrasonic detection mounting frame 310 through a mounting rod 3421, the bending part of the collecting plate 3422 is opposite to the resistor unit 520, and the first joint 3423 connected to the pumping device 350 is installed at the bending part of the collecting plate 3422. During the directional movement of the metal strip resistor 500, the coupling agent on the first side surface of the metal strip resistor 500 can continue to flow to the bending part of the collecting plate 3422 to complete centralized collection, and finally realize unidirectional pumping from the outside of the first joint 3423; the collecting plate 3422 with a bending design can collect the coupling agent in a centralized manner, thereby improving the efficiency of coupling agent collection.

[0054] For the inclined metal strip resistor 500, the collecting plate 3422 can be selected as an additional Fig.10 In the L-shaped collecting structure shown, the longer inclined side of the collecting plate 3422 can be installed at the lower position; for the horizontally arranged metal strip resistor 500, the collecting plate 3422 here can be designed as a bent V-shape, which can efficiently and centrally guide the collection of the coupling agents on both sides.

[0055] Specifically, the ultrasonic detector 332 includes an ultrasonic detection probe 3322, and a control shaft 3321 is installed between the ultrasonic detection probe 3322 and the ultrasonic detection mounting frame 310, and the deflection angle of the ultrasonic detection probe 3322 can be adjusted by the control shaft 3321; a coupling agent coating end 3323 is installed on the outer side of the ultrasonic detection probe 3322, and a second connector connected to the pumping device 350 is installed on the surface of the coupling agent coating end 3323.

[0056] The second joint here is located on the front side of the conveying direction of the metal strip resistor 500, and the coupling agent can be applied to the predetermined position in front of the ultrasonic detection probe 3322; the overall deflection angle of the ultrasonic detection probe 3322 and the coupling agent filling end 3323 can be adjusted by controlling the rotating shaft 3321, and the position where the coupling agent is sprayed can be adjusted to increase the range of the coupling agent filling; for larger welding areas, the deflection and swing range of the ultrasonic detection probe 3322 can be expanded to meet the needs of ultrasonic detection of metal strip resistors 500 of different sizes.

[0057] Specifically, the surface cleaning device 320 includes a surface cleaning component 322 located on the first side of the metal strip resistor 500 and a first support roller 321 located on the second side of the metal strip resistor 500. The first support roller 321 can support the metal strip resistor 500 from the second side to prevent the metal strip resistor 500 from deforming during the cleaning process, thereby ensuring the stability of the metal strip resistor 500 during the cleaning process.

[0058] The surface cleaning component 322 here extends in a direction perpendicular to the conveying direction of the metal strip resistor 500. The surface cleaning component 322 is arranged parallel to the surface of the metal strip resistor 500. The surface cleaning component 322 can fit the surface of the metal strip resistor 500. During the continuous operation of the surface cleaning component 322, the surface of the metal strip resistor 500 is continuously cleaned in a direction perpendicular to the conveying direction of the metal strip resistor 500. The metal strip resistor 500 can be conveyed in a first direction. The surface cleaning component 322 can continuously clean the raised obstacles on the surface of the metal strip resistor 500 in a second direction perpendicular to the first direction.

[0059] Through the above-mentioned cleaning method, there will be no pressure on the surface of the metal strip resistor 500, thereby avoiding damage to the metal strip resistor 500 during the cleaning process; at the same time, the raised obstacles cleaned along the second direction can move along the composite direction of the second direction and the first direction, and can be quickly discharged from the surface of the metal strip resistor 500, thereby avoiding the residue of the raised obstacles.

[0060] An air blowing device may be installed outside the metal strip resistor 500, which can further increase the rate of removing raised obstacles after cleaning and improve the cleaning effect.

[0061] Please refer to the attached Figure 8 As Example 1 of the surface cleaning component 322, the surface cleaning component 322 here includes a first cleaning rod 3221, a first mounting sleeve 3222 is fixed on the surface of the first cleaning rod 3221, a serpentine cleaning strip 3223 is fixed on the surface of the first mounting sleeve 3222, the cleaning strip 3223 extends along the axial direction of the first cleaning rod 3221, and also includes a first driving component for controlling the directional rotation of the first cleaning rod 3221.

[0062] While controlling the first cleaning rod 3221 to continuously rotate, the cleaning bar 3223 can be driven to rotate synchronously. Since the cleaning bar 3223 is a serpentine structure, during the continuous rotation of the cleaning bar 3223, the raised obstacles on the surface of the metal strip resistor 500 can be continuously cleaned through the side wall of the cleaning bar 3223, thereby achieving efficient and continuous cleaning.

[0063] Please refer to the attached Fig. 9 As embodiment 2 of the surface cleaning component 322, the surface cleaning component 322 includes a second cleaning rod 3224, a second mounting sleeve 3225 is fixed on the surface of the second cleaning rod 3224, a plurality of cleaning discs 3226 arranged at intervals are fixed on the surface of the second mounting sleeve 3225, and also includes a second driving component for controlling the reciprocating movement of the second cleaning rod 3224.

[0064] In the process of controlling the reciprocating movement of the second cleaning rod 3224, the cleaning disk 3226 can also be driven to continuously reciprocate at a high frequency. In the process of the high-frequency reciprocating movement of the cleaning disk 3226, the raised obstacles can be continuously and efficiently cleaned through the side wall of the cleaning disk 3226.

[0065] Finally, it should be noted that the distance between the two cleaning disks 3226 and the frequency of the reciprocating movement of the cleaning disk 3226 are determined comprehensively based on the distribution and number of raised obstacles on the surface of the metal strip resistor 500. The minimum reciprocating frequency can be guaranteed while ensuring efficient cleaning of the surface of the metal strip resistor 500.

[0066] The present invention is further described below in conjunction with the detection process.

[0067] An electron beam welded component inspection process, using the electron beam welded component inspection device, comprises the following steps: S1. Control the metal strip resistor 500 to move in a directional manner along a predetermined track. The metal strip resistor 500 first passes through the first image detection mechanism 200. The first image detection mechanism 200 performs image detection on the first side surface of the metal strip resistor 500. Image detection of surface defects on the first side of the metal strip resistor 500 is achieved.

[0068] S2. The metal strip resistor 500 passes through the ultrasonic detection mechanism 300 again, and the ultrasonic detection mechanism 300 performs continuous ultrasonic detection on the metal strip resistor 500; the ultrasonic detection mechanism 300 is located on the first side to perform ultrasonic detection on the surface of the metal strip resistor 500, and at the same time, the coupling agent is filled on the first side of the surface of the metal strip resistor 500. Since the first side of the metal strip resistor 500 has been image-detected, it will not have any impact.

[0069] By locating the ultrasonic detection mechanism 300 on the first side, ultrasonic detection can be performed on the inside of the metal strip resistor 500, and partial defects existing inside the metal strip resistor 500 can be detected in real time. Image detection and ultrasonic detection can be recorded and retained at the same time, leaving a basis for subsequent detection and maintenance of the metal strip resistor 500.

[0070] S3. The metal strip resistor 500 finally passes through the second image detection mechanism 400, and the second image detection mechanism 400 performs image detection on the second side surface of the metal strip resistor 500.

[0071] Among them, the ultrasonic detection mechanism 300 includes a surface cleaning device 320 and an ultrasonic detection component 330. The surface cleaning device 320 continuously operates to continuously clean the first side surface of the metal strip resistor 500. By continuously cleaning the surface of the metal strip resistor 500, the continuity and stability of the ultrasonic detection can be guaranteed.

[0072] The ultrasonic detection component 330 includes an ultrasonic detector 332 located on the first side of the metal strip resistor 500 and a second supporting roller 331 located on the second side of the metal strip resistor 500. The ultrasonic detector 332 is used to continuously perform ultrasonic detection on the coupling agent applied to the surface of the first side of the metal strip resistor 500. Through the above structure, the smoothness of the ultrasonic detection can be guaranteed, and all-round detection of the surface and interior of the metal strip resistor 500 can be achieved.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
