Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection of mobile phone frames, and more specifically, the utility model relates to an ultrasonic detection mechanism for mobile phone frame strips. Background Art

[0002] Flaw detection of mobile phone frame strips usually refers to non-destructive testing of the frame strips of mobile phone cases to ensure the integrity and safety of their welded parts. The common shapes of mobile phone frames are L-shaped or U-shaped. When performing flaw detection, it is necessary to perform flaw detection on the entire mobile phone frame along the shape of the mobile phone frame. Currently, there are two optional flaw detection methods: magnetic particle flaw detection and ultrasonic flaw detection. When using ultrasonic flaw detection, due to the complex shape of the mobile phone frame strip, the general flaw detection method is a handheld flaw detector, and manual contact is used to detect the middle frame of the mobile phone, resulting in low efficiency.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] As Figures 1 to 3 A specific embodiment of the present invention, its structure includes a flaw detection tank 1, and its structure also includes a probe 11. A workbench 12 is provided at the bottom of the flaw detection tank 1. A number of placement stations 13 for placing mobile phone frames are provided on the surface of the workbench 12. An adjusting member 2 is provided outside the flaw detection tank 1.

[0017] In the present invention, the mobile phone frame to be detected is placed on the placement station 13. According to the shape of the mobile phone frame, the adjusting member 2 adjusts the movement of the probe 11 on the X, Y, and Z axes, and can automatically realize the all-round detection of the mobile phone frame. At the same time, by rotating the probe 11 on the W axis, the probe 11 can always be perpendicular to the detection position of the mobile phone frame, ensuring the accuracy of the detection by the probe 11.

[0018] In the present invention, as a preferred solution, a number of fixing blocks 3 are provided on the workbench 12. A placement station 13 is formed between two adjacent fixing blocks 3.

When the mobile phone frame is placed on the placement station 13, the mobile phone frame is elastically pressed against the fixing blocks 3 by the clamping blocks 35.

[0019] In the present invention, the placement principle of the mobile phone frame is as follows: First, use an external force to push one end of the substrate 34, so that the substrate 34 moves elastically in the direction of the fixing column 33. At this time, the distance between the clamping blocks 35 and the fixing blocks 3 increases, and the mobile phone frame is stuck on the placement station 13. Remove the external force. Under the elastic recovery action of the substrate 34, the substrate 34 moves away from the fixing column 33, so that the clamping blocks 35 elastically press the mobile phone frame against the fixing blocks 3.

[0020] In the present utility model, as a preferred solution, two protruding blocks 4 are provided on the side surface of the above-mentioned fixing block 3, and the two protruding blocks 4 are symmetrically located on both sides of the through groove 32.

[0021] In the present utility model, when the clamping block 35 presses the mobile phone frame against the fixing block 3, the mobile phone frame abuts against the two protruding blocks 4, ensuring the stability of the mobile phone frame being pressed tightly on the fixing block 3.

[0022] In the present utility model, as a preferred solution, a sleeve 41 is provided at the end of the substrate 34, a buffer spring 42 is provided inside the sleeve 41, and the sleeve 41 is slidably arranged on the fixed column 33 and fixedly connected to the buffer spring 42.

[0025] In the present utility model, the working principle of the adjusting member 2 is as follows: the position of the horizontal slider 61 is adjusted by the horizontal driving member 62, thereby adjusting the position of the support seat 63 in the X-axis direction. Subsequently, the position of the vertical slider 66 is adjusted by the vertical driving member 67, thereby adjusting the position of the vertical plate 68 in the Y-axis direction. Finally, the position of the vertical slider 7 is adjusted by the vertical driving member 71, thereby adjusting the position of the flaw detection plate 73 in the Z-axis direction. During specific flaw detection, the probe 11 is driven to rotate by the rotary driving member 5, ensuring that the probe 11 is always perpendicular to the mobile phone frame and ensuring the accuracy of flaw detection by the probe 11.

[0026] In the present utility model, as a preferred solution, the above-mentioned lateral driving member 62, longitudinal driving member 67 or vertical driving member 71 all use a driving motor as the power source, a lead screw as the transmission mechanism, and drive the lateral slider 61, longitudinal slider 66 or vertical slider 7 to move through screw transmission.
