Description

Technical Field

[0001] This application relates to the field of ultrasonic scanning technology, and in particular to a multi-channel water removal device for ultrasonic scanning. Background Technology

[0002] Ultrasonic scanning is an important non-destructive testing technique in the field of process testing instruments. It mainly detects internal structural defects in materials by measuring the difference in acoustic impedance of ultrasonic waves. This technology is widely used in semiconductors, 3D packaging, MEMS wafer inspection, SOI substrate manufacturing, and other fields, and can detect hidden defects such as delamination, cracks, and air pockets.

[0003] To increase the accuracy of ultrasonic scanning, the workpiece is usually placed underwater for scanning. After scanning, the water needs to be removed before proceeding to the next step. Current industrial production lines use robotic arms to move the workpiece and use air blowing to remove water. Although this can remove most of the water from the surface of the workpiece, water is still likely to remain in the corners of the workpiece. Since the bottom of the workpiece is placed on a support plate or conveyor belt, it is also difficult to completely remove water from the bottom surface. Summary of the Invention

[0004] This application provides a multi-channel water removal device for ultrasonic scanning, which can reliably remove moisture from the inside corners and bottom surfaces of workpieces, thereby improving the water removal rate.

[0005] This application provides a multi-duct water removal device for ultrasonic scanning, which adopts the following technical solution:

[0006] An ultrasonic scanning multi-channel dewatering device includes a base shell, a cover shell, and a conveyor belt. The conveyor belt passes between the base shell and the cover shell. Multiple air blowing pipes are provided inside the cover shell. The conveyor belt is a perforated belt. A support plate is fixed to the cover shell and is attached to the top and bottom surfaces of the conveyor belt. The support plate is also a perforated plate. Two cylinders are fixed inside the cover shell. A sponge-material clamping block is fixed to the telescopic end of each cylinder. The clamping direction of the clamping block is the width direction of the workpiece. Two rotary cylinders are fixed inside the cover shell. A sponge-material clamping block is fixed to the movable end of each rotary cylinder. The clamping direction of the clamping block is the front-back direction of the workpiece. The shapes of the clamping blocks are adapted to the outer wall shape of the workpiece.

[0007] By employing the above technical solution, as the workpiece moves with the conveyor belt, cylinder one actuates, and two clamping blocks clamp the workpiece from both sides. The sponge material effectively absorbs water from the corners on both sides of the workpiece. After clamping the workpiece, as the conveyor belt continues to move, the bottom surface of the workpiece moves relative to the conveyor belt, thus misaligning the original draining position of the workpiece. The dry area of ​​the conveyor belt also brushes against the bottom surface of the workpiece, reducing moisture. After a few seconds, clamping blocks one releases the workpiece, and the workpiece continues to move with the conveyor belt. Then, a rotary cylinder actuates, and two clamping blocks two clamp the workpiece from both the front and rear sides, again using the sponge material to absorb water from the corners on both sides of the workpiece. As the rotary cylinder applies force, clamping blocks two are squeezed and deformed, lifting the workpiece off the surface of the conveyor belt, exposing the bottom surface of the workpiece. This allows for efficient water removal from the bottom surface under the action of airflow. After a few seconds, clamping blocks two release the workpiece, rotate back to their original position, and the workpiece continues to move with the conveyor belt.

[0008] Optionally, an air knife is fixed at the inlet end of the cover, the air knife is located above the conveyor belt, and the air outlet of the air knife is set downward.

[0009] By adopting the above technical solution, before the workpiece reaches the position of the air blower, the strong air blown out by the air knife can remove most of the water on the surface of the workpiece.

[0010] Optionally, the movable range of the clamping blocks one and two is located below the blower pipe.

[0011] By adopting the above technical solution, the airflow inside the cover can dry the first and second clamps. The sponge material of the first and second clamps is easy to be dried by the wind due to its porous and loose material. The first and second clamps will not have excessive moisture even after continuous use.

[0012] Optionally, the air blowing pipes are distributed above and below the conveyor belt, with the upper air blowing pipe opening downwards and the lower air blowing pipe opening upwards.

[0013] By adopting the above technical solution, both the top and bottom of the workpiece can be dried by blowing air. The collision point of the upper and lower airflows generates turbulence, which can also dry the workpiece by blowing air.

[0014] Optionally, the blower tube is a tapered diffuser tube.

[0015] By adopting the above technical solution, the diffuser tube has the effect of reducing speed and increasing pressure, and expanding the area of ​​airflow.

[0016] Optionally, two sets of conveyor belts are arranged side by side, with the two sets of conveyor belts having opposite conveying directions.

[0017] By adopting the above technical solution, one conveyor belt is used for the outbound journey, and the other for the return journey. During the return journey, the workpiece passes through the casing again and is blown by the air pipe again, further ensuring that the workpiece is dry. Since the workpiece is input into the device from both the beginning and end positions, it is convenient for the front-end robot to transport the dehydrated workpiece to the next process.

[0018] Optionally, the housing is fixed with a distributor, which has an air inlet connector and multiple air outlet connectors, and the air outlet connectors correspond one-to-one with the connectors of the blower pipe.

[0019] By adopting the above technical solution, compressed air is evenly distributed to each blower pipe through the distributor.

[0020] Optionally, the housing is equipped with a photoelectric sensor, which is electrically connected to the cylinder via a controller.

[0021] By adopting the above technical solution, photoelectric sensor 1 is used to detect the workpiece passing by, and then the controller controls cylinder 1 to run automatically.

[0022] Optionally, the housing is equipped with a second photoelectric sensor, which is electrically connected to the rotary cylinder via a controller.

[0023] By adopting the above technical solution, the photoelectric sensor 2 is used to detect the workpiece passing by, and then the controller controls the rotary cylinder to run automatically.

[0024] Optionally, the bottom shell is surrounded by a barrier, and a drain pipe is provided at the bottom of the bottom shell.

[0025] By adopting the above technical solution, the bottom shell receives the water above and drains the accumulated water through the downpipe, while the enclosure is used to prevent water from overflowing from the bottom shell.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By using clamping block one and clamping block two together, water is absorbed in all four directions around the rectangular workpiece, so that water can be removed even in the corners where water is easily left behind.

[0028] 2. By wiping the bottom surface of the workpiece with the conveyor belt and lifting the workpiece away from the conveyor belt, water accumulation on the bottom of the workpiece is avoided, resulting in a higher water removal rate.

[0029] 3. The strong air blown by the air knife removes most of the water from the surface of the workpiece, and then the remaining water on the surface of the workpiece is removed through multiple air pipes, resulting in high water removal efficiency. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 and Figure 2 This embodiment discloses a multi-channel water removal device for ultrasonic scanning, including a bottom shell 1, a cover 2, and a conveyor belt 3. The conveyor belt 3 passes through the space between the bottom shell 1 and the cover 2. The conveyor belt 3 is a perforated belt, such as a mesh belt. The cover 2 is fixed with a support plate 31, which is attached to the bottom surface of the upper belt surface of the conveyor belt 3. The support plate 31 is a perforated plate, such as a mesh plate. Two sets of conveyor belts 3 are arranged side by side, with the two sets of conveyor belts 3 arranged in opposite directions. One set is used for the outbound journey, and the other set is used for the return journey.

[0038] The mesh or porous structure of the conveyor belt 3 and the support plate 31 is used to ensure ventilation. The support plate 31 supports the upper surface of the conveyor belt 3 to prevent the upper surface of the conveyor belt 3 from bending downwards.

[0039] An air knife 21 is fixed at the inlet end of the casing 2, located above the conveyor belt 3, with its outlet facing downwards. The air knife 21 blows a strong, narrow airflow from the bottom slit to initially remove water from the workpiece. The strong airflow from the air knife 21 can remove most of the water from the workpiece surface. A baffle 11 is provided around the bottom shell 1, and a drain pipe 12 is located at the bottom inner part of the bottom shell 1. The bottom shell 1 collects water from above and then discharges the accumulated water through the drain pipe 12.

[0040] Reference Figure 2 and Figure 3The housing 2 contains multiple air blowing pipes 22, distributed above and below the conveyor belt 3. The air blowing pipes 22 are fixedly connected to the housing 2 via plates. The upper air blowing pipes 22 have their openings facing downwards, while the lower air blowing pipes 22 have their openings facing upwards, thus achieving the effect of blowing away moisture from both the top and bottom of the workpiece. The air blowing pipes 22 are tapered diffusers, which have the function of reducing speed and increasing pressure, expanding the effective area of ​​the airflow. The collision point of the upper and lower airflows generates turbulence, which also achieves the effect of blowing and drying the workpiece.

[0041] The housing 2 is fixed with a distributor 4, which has an air inlet connector 41 and multiple air outlet connectors 42. The air outlet connectors 42 correspond one-to-one with the connectors of the blower pipes 22. By connecting the air inlet connector 41 to the compressed air source and connecting the multiple air outlet connectors 42 to the inlets of the blower pipes 22 one-to-one with the air pipes, the compressed air can be evenly distributed to each blower pipe 22 and blown out.

[0042] Reference Figure 3 and Figure 4 Inside the housing 2, two cylinders 5 are fixed. The telescopic ends of cylinders 5 are fitted with sponge-material clamping blocks 51. The clamping direction of the clamping blocks 51 is the width direction of the workpiece. The two clamping blocks 51 are symmetrically arranged to clamp the workpiece from both sides. The shape of the clamping blocks 51 is adapted to the shape of the outer wall of the workpiece, allowing them to contact the inner corners on both sides of the workpiece. The sponge material absorbs water from these inner corners. After the clamping blocks 51 clamp the workpiece, as the conveyor belt 3 continues to move, the bottom surface of the workpiece moves relative to the conveyor belt 3, thus misaligning the original draining position of the workpiece. The dry area of ​​the conveyor belt 3 can also wipe over the bottom surface of the workpiece, reducing moisture on the bottom surface.

[0043] Reference Figure 4 and Figure 5 Inside the housing 2, two rotary cylinders 6 are fixed. The movable ends of the rotary cylinders 6 are fixed with sponge-material clamping blocks 61. The clamping direction of the clamping blocks 61 is the front-to-back direction of the workpiece. The two clamping blocks 61 are symmetrically arranged front and back, used to clamp the workpiece from both the front and back sides. The shape of the clamping blocks 61 is adapted to the shape of the outer wall of the workpiece, allowing them to contact the internal corners on both the front and back sides of the workpiece. The sponge material absorbs water from these corners. When the clamping blocks 61 rotate upwards, they move away from the conveyor belt 3, not affecting the movement of the workpiece along the conveyor belt 3. When the clamping blocks 61 rotate downwards, they clamp the workpiece. Due to the elasticity of the sponge material, the clamping blocks 61 are compressed and deformed by the force applied by the rotary cylinders 6, lifting the workpiece off the surface of the conveyor belt 3, exposing the bottom surface of the workpiece. This allows for efficient water removal from the bottom surface under the action of airflow.

[0044] Reference Figure 3The movement range of clamping blocks 51 and 61 is located below the air blowing pipe 22. With this setting, after clamping blocks 51 and 61 are separated from the workpiece, the airflow inside the cover 2 can dry clamping blocks 51 and 61. Due to their porous and loose material, clamping blocks 51 and 61 made of sponge are easily dried by the wind.

[0045] Reference Figure 1 and Figure 3 The housing 2 is equipped with a photoelectric sensor 23, which is electrically connected to the cylinder 5 via a controller. The photoelectric sensor 23 detects the passing of a workpiece, and then the controller automatically operates the cylinder 5. The photoelectric sensor 23 is installed in a strip groove and secured with a nut. The position of the photoelectric sensor 23 relative to the conveyor belt 3 can be adjusted, thereby regulating the timing of the cylinder 5's start.

[0046] The housing 2 is equipped with a second photoelectric sensor 24, which is electrically connected to the rotary cylinder 6 via a controller. The second photoelectric sensor 24 detects the passing of a workpiece, and then the controller controls the rotary cylinder 6 to operate automatically. The position of the second photoelectric sensor 24 is also adjustable, in the same way as the first photoelectric sensor 23.

[0047] The implementation principle of the ultrasonic scanning multi-duct dewatering device according to an embodiment of this application is as follows: This dewatering device is suitable for rectangular workpieces. After the workpiece completes ultrasonic scanning, it is transported to the front end of the conveyor belt 3 by a robotic arm. Since the workpiece is transported by a robotic arm, the position of the workpiece relative to the width of the conveyor belt 3 is the same, and the angle after placement is also the same, ensuring that the subsequent clamping blocks 51 and 61 clamp the workpiece.

[0048] Conveyor belt 3 runs continuously. The workpiece first passes through air knife 21 to remove most of the moisture. When photoelectric sensor 23 detects the workpiece, the controller controls cylinder 5 to actuate. Two clamping blocks 51 clamp the workpiece from the left and right sides, and the sponge material absorbs water from the corners on both sides of the workpiece. After clamping the workpiece, as conveyor belt 3 continues to move, the bottom surface of the workpiece moves relative to conveyor belt 3, thus misaligning the original draining position of the workpiece with the workpiece. The dry area of ​​conveyor belt 3 can also wipe the bottom surface of the workpiece, reducing the moisture on the bottom surface. After a few seconds, the controller controls clamping blocks 51 to release the workpiece, and the workpiece continues to move with conveyor belt 3.

[0049] When photoelectric sensor 24 detects the workpiece, the controller activates rotary cylinder 6. Two clamping blocks 61 clamp the workpiece from both the front and rear sides, using a sponge material to absorb water from the inner corners. As the rotary cylinder 6 applies force, clamping blocks 61 are deformed, lifting the workpiece off the surface of conveyor belt 3, exposing its bottom surface for efficient water removal under airflow. After a few seconds, clamping blocks 61 release the workpiece, rotate back to their original position, and the workpiece continues to move with conveyor belt 3.

[0050] After the workpiece reaches the end of conveyor belt 3, it is transferred by another robotic arm to an adjacent conveyor belt 3. During the return journey, the workpiece passes through the cover 2 again and is blown by the air pipe 22 again to further ensure that the workpiece is dry. Since the workpiece is input into the device at both the beginning and end positions, it is convenient for the robotic arm at the front to transfer the dehydrated workpiece to the next process.

[0051] In summary, by using clamping block 51 and clamping block 61 together, water can be absorbed from all four circumferential directions of the rectangular workpiece, so that water can be removed from the corners where water is easily retained, while avoiding water accumulation on the bottom of the workpiece, resulting in a higher water removal rate.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
