Description

Technical Field

[0001] The present invention is applied to the technical field of ultrasonic testing, and particularly relates to a semi-automatic ultrasonic testing machine. Background Art

[0002] In the modern 3C industry, there are defects such as air bubbles, cracks, and sand holes inside metal products. Therefore, defect detection is a very common and necessary process to pick out defective products. During the production and manufacturing process of these products, defect inspection has become a most basic operation. The traditional detection process uses manual ultrasonic detectors held by workers to detect single products. This primitive manual operation method requires a large number of assembly workers, with low labor efficiency, low product output value, and the stability of product detection cannot be guaranteed. For example, in the existing process for detecting defects in the material bonding surface of mobile phone middle frame raw material products, ultrasonic detection is carried out on single products by manually holding an ultrasonic detector or a semi-automatic tooling. Therefore, there are often disadvantages such as uneven testing speed, image changes caused by jitter, inaccurate control of detection distance, low efficiency, and difficulty in tool change. If a semi-automatic ultrasonic testing machine with a simple structure, capable of dual-station operation, high detection efficiency, high compatibility, and capable of meeting products with various model shapes can be designed, the above problems can be solved. Summary of the Invention

[0006] Further, the U-axis module for detection includes a U-axis bracket, a U-axis motor, and a bubble removal device. The upper end of the U-axis bracket is connected to the movable end of the Z-axis linear module.

The movable end of the U-axis motor is rotationally matched with the bubble removal device. The bubble removal device is matched with a plurality of the products on the fixture lifting assembly.

[0007] Further, a detection probe is arranged at the upper end of the bubble removal device. The detection probe is connected and conducted with the ultrasonic detection module. The detection probe is inductively matched with a plurality of products on the fixture lifting assembly.

[0008] Further, the fixture lifting assembly includes a fixture support plate, a product fixture, and a fixture lifting module. A lifting through hole is arranged in the middle of the support table. Both ends of the fixture support plate are connected to both sides of the lifting through hole through the fixture lifting module.

The fixture lifting module drives the product fixture to cooperate with the water tank assembly. An anti-fooling optical fiber is arranged at one end of the fixture support plate.

[0009] Further, the product fixture includes a fixture base, a product support plate, and product pressing blocks. The product support plate is arranged on the upper end surface of the fixture base. A plurality of the product pressing blocks are floatingly connected to one side of a plurality of product placement positions on the product support plate through floating springs. The floating springs drive the product pressing blocks to make a plurality of the products cooperate with the plurality of product placement positions on the product support plate.

[0010] Further, the water tank assembly includes a box body, a drain pipe, a water inlet pipe, and a water pump. The box body is arranged at the lower end of the support table. The drain pipe and the water inlet pipe are respectively connected to the drainage end and the water inlet end of the box body. The water pump is matched with the water inlet pipe.

Through several sensing modules, the position of the product and the water surface height can be effectively identified and fed back to the next component for timely adjustment. When implementing ultrasonic detection, the defoaming device is used to perform defoaming operation on the product surface, with simple structure and better detection effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] As Figures 1 to 7 shown, in this embodiment, the present invention includes a support platform 1, an ultrasonic detection component 2, a fixture lifting component 3, and a water tank component 4. The ultrasonic detection component 2 and the water tank component 4 are respectively arranged at the upper and lower ends of the support platform 1. The ultrasonic detection component 2 includes a detection bracket 5, a detection three-axis module 6, an ultrasonic detection module 7, and a detection U-axis module 8. The detection bracket 5 is arranged on the upper end surface of the support platform 1. The detection end of the detection U-axis module 8 is connected and conducted with the ultrasonic detection module 7. The detection three-axis module 6 drives the detection end of the detection U-axis module 8 to cooperate with a plurality of products 9 on a plurality of fixture lifting components 3 in the water tank component 4. Thus, it can be seen that the detection three-axis module 6 and the detection U-axis module 8 cooperate to realize the adjustment in the three-axis and rotation axis directions, and the detection end on the detection U-axis module 8 is matched with the products on the fixture lifting component 3 to realize ultrasonic detection at multiple angles.

[0017] As Figure 2As shown in the figure, in this embodiment, the detection three-axis module 6 includes an X-axis linear module 61, a Y-axis linear module 62, and a Z-axis linear module 63. The X-axis linear module 61 is disposed at the upper end of the detection bracket 5. The Y-axis linear module 62 is connected to the movable end of the X-axis linear module 61. The ultrasonic detection module 7 is connected to the movable end of the Y-axis linear module 62 through a connection plate 10. The Z-axis linear module 63 is connected to the connection plate 10. The detection U-axis module 8 is connected to the movable end of the Z-axis linear module 63. It can be seen that the X-axis linear module 61, the Y-axis linear module 62, and the Z-axis linear module 63 can be adjusted in the X, Y, and Z axis directions, and cooperate with the detection U-axis module 8 to achieve four-axis adjustment, so that the detection module can perform ultrasonic detection on multiple directions of the product 9, and the detection range is wider.

[0018] As Figure 3 shown in the figure, in this embodiment, the detection U-axis module 8 includes a detection U-axis bracket 81, a U-axis motor 82, and a degassing device 83. The upper end of the U-axis bracket 81 is connected to the movable end of the Z-axis linear module 63. The U-axis motor 82 and the degassing device 83 are respectively disposed in the middle and lower ends of the U-axis bracket 81. The movable end of the U-axis motor 82 is rotationally matched with the degassing device 83. The degassing device 83 is matched with a plurality of the products 9 on the fixture lifting assembly 3. It can be seen that the degassing device 83 performs a defoaming operation on the surface of the product 9 to avoid the influence of bubbles on ultrasonic detection.

[0019] As Figure 3 shown in the figure, in this embodiment, a detection probe 84 is disposed at the upper end of the degassing device 83. The detection probe 84 is connected and conducted with the ultrasonic detection module 7. The detection probe 84 is inductively matched with a plurality of products 9 on the fixture lifting assembly 3. It can be seen that the detection probe 84 performs a scanning detection on multiple directions of the product 9 through four-axis control.

[0020] As Figure 1 and Figure 4As shown, in this embodiment, the jig lifting assembly 3 includes a jig support plate 31, a product jig 32 and a jig lifting module 33. A lifting port 13 is provided in the middle of the support platform 1. The two ends of the jig support plate 31 are connected to the two sides of the lifting port 13 through the jig lifting module 33. The product jig 32 is connected to the middle of the jig support plate 31 through the jig positioning plate 34. The jig lifting module 33 drives the product jig 32 to cooperate with the water tank assembly 4. An anti-fool optical fiber 35 is provided at one end of the jig support plate 31. It can be seen that the jig lifting module 33 drives the product jig 32 to descend so that a number of the products 9 are immersed in the water of the water tank assembly 4 to cooperate with the detection probe 84 for ultrasonic detection.

[0021] like Figure 5 As shown, in this embodiment, the product jig 32 includes a jig base 321, a product support plate 322 and a product pressing block 323. The product support plate 322 is arranged on the upper end surface of the jig base 321. Several product pressing blocks 323 are floatingly connected to one side of several product placement positions on the product support plate 322 through floating springs 324. The floating springs 324 drive the product pressing blocks 323 to make several products 9 match with several product placement positions of the product support plate 322. It can be seen that a group of product support plates 322 can realize the positioning and fixation of 12 products 9 of different specifications, such as U-shaped products and L-shaped products. Different product shapes can be matched with four-axis adjustment to perform ultrasonic detection at different angles, and the applicability is strong.

[0022] like Figure 6 As shown, in this embodiment, the water tank assembly 4 includes a box body 41, a drain pipe 42, a water inlet pipe 43 and a water pump 44. The box body 41 is arranged at the lower end of the support platform 1. The drain pipe 42 and the water inlet pipe 43 are respectively connected to the drain end and the water inlet end of the box body 41. The water pump 44 cooperates with the water inlet pipe 43. The detection three-axis module 6 drives the fixture lifting assembly 3 to cooperate with the inside of the box body 41. It can be seen that the water level raised when the product fixture 32 falls into the box body 41 is discharged through the drain pipe 42 to prevent water from overflowing. After completing the single group detection, it is replenished through the water pump 44 and the water inlet pipe 43.

[0023] like Figure 6 As shown, in this embodiment, a liquid level sensor 11 is provided on one side of the box body, and the liquid level sensor 11 cooperates with the liquid induction in the box body 41. It can be seen that the liquid level sensor 11 can sense the page height in the box body 41 and control the water inlet pipe 43 or the drain pipe 42 to adjust.

[0024] like Figure 1 andFigure 7 As shown in the figure, in this embodiment, operation table components 12 are provided on both sides of the support table 1. The operation table component 12 includes an operation support plate 121, a two-hand start button 122, an emergency stop button 123, and an indicator light module 124. It can be seen that the operation table component 12 can be used for storing the product fixture 32 and starting and stopping the machine.

[0025] As Figure 7 shown in the figure, in this embodiment, the product fixture 32 is matched with the buffer position in the middle of the upper end surface of the operation support plate 121. It can be seen that the limit cooperation between the product fixture 32 and the buffer position in the middle of the upper end surface of the operation support plate 121 can prevent the product fixture 32 from colliding and falling off.

[0026] Working principle of the present invention: Before the equipment is started, the operator places 12 groups of the products 9 into the product fixtures 32 at the buffer position in the middle of the upper end surface of the operation support plate 121. The product fixtures 32 after loading are placed on the fixture positioning plate 34 on the fixture support plate 31. The anti-fooling optical fiber 35 detects whether the products 9 are placed properly. The fixture lifting module 33 drives the product fixture 32 into the water surface. The X-axis linear module 61, the Y-axis linear module 62, the Z-axis linear module 63, and the U-axis motor 82 drive the bubble removal device 83 to perform bubble removal operation on the products 9. After the bubble removal operation is completed, the detection probe 84 performs ultrasonic detection on the products 9 and feeds the detection results back to the external data analysis component. After a group of product fixtures 32 complete the detection, they float out of the water surface. The operator at another operation station repeats the above steps, and multi-station multi-product bubble removal and ultrasonic inspection can be achieved.

[0027] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation to the meaning of the present invention. For those skilled in the art, the modifications to its implementation solutions according to this specification and the combinations with other solutions are obvious.
