[0002] New energy vehicle batteries need to be cooled. Water cooling is the current mainstream cooling solution. Square battery cells need to use coolant cold plates for cooling. For the production of some coolant cold plates, continuous gas shielded brazing of the plate body and the end is required. Brazing has the advantages of high production efficiency and good product consistency. However, the welding joint rate inside the welded cold plate cannot be judged manually.

And there may be residual flux crystallization in the internal flow channels of the product, resulting in flow channel blockage and affecting the use of the product. Content of the Utility Model

[0018] A preferred embodiment of the present utility model will be described in detail below with reference to the drawings.

[0019] To achieve the above object, the embodiments of the present utility model adopt the following technical solutions: Refer to Figure 1, An ultrasonic detection device for the welding joint rate of a water-cooled plate, including a base 10, further including a manipulator 20, a positioning tooling, and a detection device. The manipulator is arranged on the side of the base, and two manipulators can be arranged opposite to each other along both sides of the base, so that the manipulators on both sides can cooperate with each other to pick and place workpieces. The positioning tooling is arranged on the top of the base and is used to fix the workpiece to be ultrasonically detected. The detection device is arranged above the positioning tooling. Further, the detection device includes a displacement mechanism capable of moving along the long side and / or short side of the positioning tooling and an ultrasonic scanner 50 arranged at the mobile end of the displacement mechanism. Specifically, the displacement mechanism includes a first moving component and a second moving component. The first moving component is arranged along the long side of the positioning tooling, and the second moving component is arranged along the short side of the positioning tooling. In this embodiment, the workpiece to be detected is a water-cooled plate. During detection, the water-cooled plate is placed in the positioning tooling and fixed. The displacement mechanism drives the ultrasonic scanner to move along the long side and / or short side of the positioning tooling, so as to move the ultrasonic scanner to a suitable position of the water-cooled plate, and uses ultrasonic waves to detect whether there are virtual welds inside the product and whether there is flux residue in the flow channel, so that the joint rate inside the product can be detected without damaging the product.

[0020] As a preferred technical solution of this embodiment, the positioning tooling includes a positioning frame 310 and a fixing member 320. The number of fixing frames is two. The positioning frame 310 is U-shaped, and the two fixing frames are arranged opposite to each other on the top of the base 10. The two fixing frames form a space for accommodating the workpiece. During use, the two positioning frames can be used in cooperation to clamp the workpiece. The fixing member 320 can be a fastener such as a bolt or a screw. The fixing member is arranged on the side wall of the positioning frame, so as to fix the water-cooled plate placed in the positioning frame laterally.

[0021] As a preferred technical solution of this embodiment, a suction cup 210 for adsorbing the workpiece is provided at the free moving end of the manipulator 20. During use, the suction cup can move freely under the control of the free end, so as to pick and place the workpiece.

[0022] As a preferred technical solution of this embodiment, the first moving component includes a first linear motor module 411 and a first sliding seat 412. The first linear motor module 411 is arranged on the top of the base 10 parallel to the long side of the positioning tooling. The first sliding seat 412 is arranged on the moving end of the first linear motor module and can move along the length direction of the first linear motor module. And the second moving component is arranged on the first sliding seat. Further, the second moving component includes a second linear motor module 421 and a second sliding seat 422. The second linear motor module 421 is arranged parallel to the short side of the positioning tooling. The second sliding seat 422 is arranged on the moving end of the second linear motor module and can move along the length direction of the second linear motor module. Further, the ultrasonic scanner is arranged on the second sliding seat. During use, the first linear motor module can be used to drive the first sliding seat to move along the long side of the positioning tooling, and the second linear motor module can be used to drive the second sliding seat to move along the short side of the positioning tooling, so as to realize the position movement of the ultrasonic scanner, so as to facilitate the detection of the internal situation of the water-cooled plate by the ultrasonic scanner.

[0023] It should be noted that the first moving component is not limited to being arranged on the long side of the positioning tooling, and the second moving component is not limited to being arranged on the short side of the positioning tooling. Their positions can be swapped, as long as it can be realized that the ultrasonic scanner moves along the long side and / or short side of the positioning tooling under the combined action of the two.

[0024] In addition, the process of the ultrasonic scanner moving along the long side and short side of the positioning tooling can be independent or the two can be synchronized. That is, the ultrasonic scanner can move alone along the long side of the positioning tooling, can move alone along the short side of the positioning tooling, and can also move synchronously along the long side and short side of the positioning tooling. There is no limitation here.

[0025] Further, the ultrasonic scanner 50 in this embodiment is an ultrasonic scanning lens.

[0026] During use, the water-cooled plate to be detected is placed in the positioning tooling by the manipulator 20, and the water-cooled plate is fixed by the positioning frame 310 and the fixing member 320. After the water-cooled plate is fixed, the first linear motor module 411 is used to drive the first sliding seat 412 to move along the long side of the positioning tooling, and the second linear motor module 421 is used to drive the second sliding seat 422 to move along the short side of the positioning tooling, so as to move the ultrasonic scanner 50 to the position to be detected of the water-cooled plate, so as to detect whether there is false soldering and whether there is residual soldering flux inside the product by the ultrasonic scanner.
