Description

Technical Field

[0001] Specifically, this invention relates to a flaw detection tooling suitable for bent copper-aluminum composite parts, and pertains to the field of flaw detection technology for copper-aluminum composite parts. Background Technology

[0002] Copper-aluminum composite strips combine the advantages of copper and aluminum materials, featuring high electrical conductivity, thermal conductivity, lightweight, corrosion resistance, and low overall cost. They are widely used in fields such as power, semiconductors, electronic devices, and new energy vehicles.

[0003] Reference Figure 1 Parts made from copper-aluminum composite strips are diverse, such as the lithium battery electrode connection plates used in new energy vehicles. These electrode connection plates are formed by bending copper-aluminum composite strips (forming a "Z" shape, consisting of three horizontal sides and two vertical sides). After bending, the electrode connection plates require flaw detection. The current problem is that existing flaw detection equipment has a row of fixed flaw detectors and a movable work platform. During inspection, the workpiece is placed on the work platform and moves relative to the flaw detectors. This flaw detection equipment is suitable for inspecting sheet-like workpieces with minimal thickness variation, but the electrode connection plate is a bent part, and the height of its vertical sides exceeds the detection range of the flaw detectors, preventing the flaw detectors from detecting the vertical sides of the electrode connection plate.

[0004] Therefore, it is necessary to design a tooling that allows the electrode connecting plate to rotate, so that the flaw detector head can perform flaw detection on the electrode connecting plate comprehensively. Summary of the Invention

[0005] To address the problems in the background art, this invention discloses a flaw detection fixture suitable for bent copper-aluminum composite parts, employing the following technical solution: A flaw detection fixture suitable for bent copper-aluminum composite parts is installed on a flaw detection equipment, which has a base, a flaw detection head, and a working platform. The flaw detection fixture mainly consists of a support, a platform, a rocker arm, and a groove plate. The support is installed on the working platform and can move with the working platform. The platform can rotate horizontally on the support and has a structure for positioning and installing the bent copper-aluminum composite parts. The groove plate is fixed on the base and has a guide groove consisting of two straight grooves and one curved groove. One end of the rocker arm is fixed to the end of the platform, and the other end is equipped with a roller. The roller can slide in the guide groove, so that the bent copper-aluminum composite parts have an inclined state in two directions during inspection.

[0006] Further improvement of the technical solution: The bent copper-aluminum composite part is groove-shaped, which is composed of one horizontal side and two vertical sides.

[0007] Further improved technical solution: The bent copper-aluminum composite part is shaped like a zigzag, consisting of three horizontal sides and two vertical sides.

[0008] Further improve the technical solution: The platform is provided with a plate-shaped body for positioning and installing the bent copper-aluminum composite component. The side of the plate-shaped body is used to position the two vertical edges of the bent copper-aluminum composite component, and the top surface of the plate-shaped body is used to position the horizontal edge of the bent copper-aluminum composite component.

[0009] Further improvement of the technical solution: The plate-shaped body is made of plastic material, and a metal shaft that can rotate horizontally on the support is inserted into the plate-shaped body. One end of the rocker arm is fixed to the end of the metal shaft by a key structure.

[0010] Further improvement of the technical solution: A cantilever is connected to the upper end of the groove plate, and the flaw detection head is installed on the cantilever with the surface facing downward.

[0011] After implementing the above technical solution, compared with the prior art, the present invention can produce the following beneficial effects: 1. Comprehensive inspection range: Guided by the guide groove, the bent copper-aluminum composite part automatically tilts twice in different directions as it moves with the working platform, adjusting its vertical edge to the range that the flaw detector head can detect, thus achieving complete flaw detection of the entire bent copper-aluminum composite part.

[0012] 2. No additional power required: The rotation of the flaw detection fixture relies entirely on the horizontal movement of the original working platform and the geometric constraint of the guide groove on the stage. There is no need to add a power source such as a motor or cylinder, which has the advantages of compact structure and low cost.

[0013] 3. High degree of automation: Operators only need to arrange the bent copper-aluminum composite parts on the platform to automatically complete the flaw detection, without manual intervention, and the detection efficiency is high. Attached Figure Description

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that in the description of the present invention, terms such as "front," "rear," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation and positional relationship, and therefore should not be construed as a limitation of the present invention. It should also be noted that in the description of the present invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0022] Reference Figure 2-3 The flaw detection fixture of the present invention is installed on existing flaw detection equipment, which has a base, a flaw detection head 8, and a working platform 2. The working platform 2 can move horizontally on the base under the drive of a lead screw, guide rail, and motor. The flaw detection fixture mainly consists of a support 3, a platform 4, a rocker arm 5, and a slotted plate 7. The support 3 is installed on the working platform 2 and can move with the working platform 2. It is worth noting that this flaw detection equipment can be an eddy current flaw detection device or an ultrasonic flaw detection device. For ultrasonic flaw detection devices, a water tank can be set on the working platform, and the flaw detection fixture can be placed in the water tank, using water as a coupling agent for ultrasonic flaw detection.

[0023] Reference Figure 4The platform 4 can rotate horizontally on the bracket 3. The platform 4 has a structure for positioning and mounting the bent copper-aluminum composite component. In this embodiment, the bent copper-aluminum composite component 1 is shaped like a triangle, consisting of three horizontal sides and two vertical sides. To position the bent copper-aluminum composite component, the main body of the platform 4 is a plate-like body 4.1. The sides of the plate-like body 4.1 are used to position the two vertical sides of the bent copper-aluminum composite component 1, and two protruding strips are provided on the top surface of the plate-like body 4.1 for positioning the horizontal sides of the bent copper-aluminum composite component 1. To reduce the interference of the plate-like body on flaw detection, the plate-like body 4.1 is made of plastic material. A metal shaft 4.2 is inserted into the plate-like body 4.1. The metal shaft 4.2 engages with a hinge hole on the bracket 3, allowing the platform 4 to rotate horizontally on the bracket 3.

[0024] The upper end of the rocker arm 5 is fixed to the end of the metal shaft 4.2 by a key structure, and a roller 6 is provided at the lower end of the rocker arm 5, which is arranged in a horizontal direction. When the rocker arm 5 swings under the action of external force, the platform 4 swings synchronously.

[0025] Reference Figure 5 The groove plate 7 is fixed to the base. A guide groove, consisting of two straight grooves 7.1 and one curved groove 7.2, is provided on the groove plate 7. The curved groove 7.2 is smoothly connected between the two straight grooves 7.1. Rollers 6 are inserted into the guide groove and can slide within it. A cantilever 7.3 is integrally connected to the upper end of the groove plate 7. A row of flaw detectors 8 is mounted on the cantilever 7.3, with the flaw detectors 8 facing downwards.

[0026] Reference Figure 6 Before flaw detection, the bent copper-aluminum composite part 1 is arranged and placed on the stage 4, and positioned by the plate 4.1. During flaw detection, the working platform 2 moves the support 3, the stage 4, and the bent copper-aluminum composite part 1 horizontally to the right. At this time, the roller 6 is located in the straight groove 7.1 on the left side of the guide groove, and the stage 4 tilts to the left, so that the vertical and horizontal edges of the right half of the bent copper-aluminum composite part 1 are displayed in an inclined state within the detection range of the flaw detection head 8. During the movement of the working platform 2, the flaw detection head 8 on the cantilever 7.3 performs flaw detection on the right half of the bent copper-aluminum composite part 1.

[0027] Reference Figure 7 As the working platform 2 moves, the roller 6 enters the curved groove 7.2 in the middle of the guide groove. At this time, the platform 4 rotates to the right to a horizontal position, and the flaw detector 8 performs flaw detection on the middle part of the bent copper-aluminum composite part 1.

[0028] Reference Figure 8As the work platform 2 continues to move, the roller 6 enters the straight groove 7.1 on the right side of the guide groove. At this time, the platform 4 tilts to the left, so that the vertical and horizontal edges of the left half of the bent copper-aluminum composite part 1 are displayed in an inclined state within the detection range of the flaw detector 8. During the movement of the work platform 2, the flaw detector 8 on the cantilever 7.3 performs flaw detection on the left half of the bent copper-aluminum composite part 1.

[0029] In this way, guided by the guide groove, the bent copper-aluminum composite 1 automatically tilts twice in different directions as it moves with the working platform 2, adjusting its vertical edge to the range that the flaw detector head 8 can detect, thus achieving complete flaw detection of the entire bent copper-aluminum composite 1.

[0030] It should be understood that the bent copper-aluminum composite is not limited to the above shape. The bent copper-aluminum composite can also be in the form of a groove, which consists of one horizontal side and two vertical sides.

[0031] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this invention should be included within the scope of protection of this invention.
