Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ultrasonic scanning equipment, and in particular to a tool for an ultrasonic scanning water tank of a sheet-shaped base material. BACKGROUND

[0002] SAT (Scanning Acoustic Tomography) detection is a machine table that transmits ultrasonic signals through pure water as a medium and detects the reflection rate and energy of high-frequency ultrasonic waves and different density materials.

[0003] SAT has a wide range of applications and can be used to scan and analyze various materials, such as chips, profiles, plates and the like. Currently, the sample is usually transported by a mechanical hand that clamps the sample. For a sheet-shaped base material with a relatively thin thickness and a relatively large surface area, a clamping jaw and a suction cup are usually used to clamp and transport the sheet-shaped base material. The clamping jaw is clamped on the side of the base material to ensure the gripping accuracy of the base material, and the suction cup is used to adsorb the base material to ensure the gripping stability of the base material.

[0004] When the mechanical jaw takes and places the base material on the jig tool, the clamping jaw will interfere and collide with the jig, and therefore, an avoiding opening for avoiding the clamping jaw is usually formed on the jig. Alternatively, the width of the jig is smaller than the width of the base material to ensure that the edge of the base material exceeds the jig, thereby avoiding the clamping jaw from touching the jig.

[0005] Both of the above methods will cause the edge of the base material to be suspended on the edge of the jig, and the ultrasonic scanning needs to be performed with the help of water as a medium. When the jig with the base material is immersed in the water tank containing water, the air below the part of the base material edge exceeding the jig cannot be discharged in time, and at this time, the air will generate a large upward thrust on the base material, thereby lifting the base material from the jig and causing the position of the base material to be deviated and tilted or even the base material to overlap, which affects the effect of ultrasonic scanning. SUMMARY

[0006] In order to ensure the scanning effect of the base material, the application provides a tool for an ultrasonic scanning water tank of a sheet-shaped base material.

[0007] The tool for an ultrasonic scanning water tank of a sheet-shaped base material provided by the application adopts the following technical scheme:

[0008] The utility model provides a kind of tool for sheet substrate ultrasonic scanning water tank, including box, rack is slidably connected in the box, a plurality of detection grooves for carrying substrate are opened in the rack, the size of detection groove is greater than the size of substrate, the two sides of detection groove are provided with avoiding mouth, the side of avoiding mouth has opening, the inner wall of avoiding mouth includes the bottom edge opposite to opening and the side edge located in the two sides of bottom edge, the bottom edge and side edge are arranged obliquely, the distance between the upper end of bottom edge and opening is less than the distance between the lower end of bottom edge and opening, the length of bottom edge is less than the length of opening.

[0009] By adopting the above technical scheme, the substrate is in the detection groove, and the two sides of the substrate are located at the avoiding mouth, but the avoiding mouth is not completely shielded, and the opening is still exposed to the air. The rack carries the substrate from top to bottom into the water tank, and the air below the two sides of the substrate located at the avoiding mouth is gradually discharged from the opening. With the process of the rack being put into the water tank, the air is squeezed between the water surface and the substrate. The bottom edge is arranged obliquely, and the air is subjected to vertical extrusion force. When the air slides along the bottom edge, the flow direction of the air extrusion is changed to an inclined direction upward and toward the opening. At this time, with the continuous lowering of the rack, the air gradually flows out along the bottom edge toward the opening, so as to guide the vertical pressure of the air to be inclined, so as to facilitate the discharge of the air and reduce the impact force of the air on the substrate upward, thereby ensuring the stability of the substrate.

[0010] Preferably, a plurality of air vents are opened in the rack, one end of the air vent is located in the inner wall of the avoiding mouth, and the other end is located on the upper surface of the rack and is arranged in a staggered manner with the substrate.

[0011] By adopting the above technical scheme, part of the air flows and is discharged in the opening direction along the bottom edge when the air is pressed, and the other part is discharged from the air vent, increasing the air discharge path and improving the air discharge effect.

[0012] Preferably, a ring of communication grooves communicating with the outside is opened in the upper surface of the rack along the bottom edge and the side edge, one end of the communication groove is located at the end of one side edge close to the opening, and the other end is located at the end of the other side edge close to the opening.

[0013] By adopting the above technical scheme, with the continuous lowering of the rack, the more air is discharged, and the remaining air is discharged from the communication groove, thereby improving the air discharge rate and reducing air residue.

[0014] Preferably, a floating prevention plate is slidably connected to the rack, and the maximum buoyancy F1 of the floating prevention plate in water is greater than the gravity G1 of the floating prevention plate, the floating prevention plate corresponds to the detection groove one by one, the floating prevention plate is slidably connected to the edge of the detection groove and located above the detection groove, when the floating prevention plate is located at the lowest position, the edge of the floating prevention plate is located in the detection groove, and when the floating prevention plate is located at the uppermost position, the edge of the floating prevention plate is not in the detection groove.

[0015] By adopting the technical scheme, the substrate is placed in the detection groove, the anti-floating plate is pressed on the upper surface of the substrate, the anti-floating plate provides downward pressure on the substrate, and the stability of the substrate is further improved, and the substrate is prevented from floating. When the substrate is completely immersed in the water tank, the anti-floating plate starts to contact the water, and as the frame continues to descend, the buoyancy of the anti-floating plate gradually increases, and when the frame is completely immersed in the water, the buoyancy of the anti-floating plate is the largest. At this time, the anti-floating plate is lifted and separated from the substrate to prevent affecting the scanning of the ultrasonic probe on the substrate.

[0016] As a preferred, the frame is provided with an inclined sliding groove from high to low, the anti-floating plate is fixed with a sliding rod which is slidingly connected in the sliding groove, and the lower end of the sliding groove is close to the detection groove, and the upper end of the sliding groove is away from the detection groove.

[0017] By adopting the technical scheme, when the anti-floating plate is lifted by the buoyancy or is lowered by the gravity, the anti-floating plate is inclined and slides along the sliding groove, which can change the position of the anti-floating plate in the vertical direction and also can change the position of the anti-floating plate in the horizontal direction, so that the surface of the substrate is completely exposed for the scanning of the ultrasonic probe.

[0018] As a preferred, the lower end of the sliding rod is fixedly connected with a buoyancy plate which is located below the frame, and the maximum buoyancy F2 of the buoyancy plate in the water is greater than the sum G3 of the gravity G2 of the buoyancy plate and the gravity G1 of the anti-floating plate.

[0019] By adopting the technical scheme, when the substrate is installed, the buoyancy plate is lifted upward by the buoyancy because the lower surface of the frame is attached to the water surface, the anti-floating plate is lifted by the buoyancy plate through the sliding rod, and at this time, the detection groove is completely exposed to facilitate the installation of the substrate.

[0020] As a preferred, the detection groove is provided with a plurality of vertically arranged abutting holes, an abutting rod is vertically and slidingly connected in the abutting hole, and an abutting spring is arranged between the abutting rod and the abutting hole. When the abutting spring is in a natural state, the upper end of the abutting rod extends out of the abutting hole, the sum F3 of the maximum buoyancy of the anti-floating plate and the buoyancy plate in the water is greater than the sum of the gravity G3 of the anti-floating plate and the buoyancy plate and the elastic force F4 of the abutting spring, and the sum of F3 and F4 is less than the gravity G4 of the substrate.

[0021] By adopting the technical scheme, when the substrate is placed in the detection groove, the substrate extrudes the abutting rod against the elastic force of the abutting spring, the lower end of the abutting rod presses the buoyancy plate against the buoyancy of the buoyancy plate, and simultaneously drives the anti-floating plate to move downward, so that the anti-floating plate is pressed on the upper surface of the substrate to improve the stability of the substrate. After the substrate is installed, the frame is completely immersed in the water, the anti-floating plate and the buoyancy plate are simultaneously lifted against the gravity and the elastic force of the abutting spring, and the anti-floating plate and the buoyancy plate are lifted to expose the substrate.

[0022] Preferably, the lower surface of the anti-floating plate is provided with a plurality of protrusions.

[0023] By using the above technical solution, the protrusions reduce the contact area between the anti-floating plate and the base material, preventing the anti-floating plate from sticking to the base material.

[0024] In summary, the present application has the following beneficial technical effects:

[0025] The bottom edge is inclined, and the air is subjected to vertical extrusion force. When the air slides along the bottom edge, the flow direction of the air extrusion upward and downward changes to an inclined direction upward and toward the opening, so as to discharge the air and reduce the impact force of the air on the upward lifting of the base material, thereby ensuring the stability of the base material.

The base material is placed in the detection grooves 21 for ultrasonic detection. Avoidance openings 22 are formed on both sides of the detection grooves 21, which are mainly used for avoiding the clamping jaw.

[0035] Referring toFigs. 1-3 The avoiding opening 22 is in the shape of a "C". The outer side of the avoiding opening 22 is in the shape of an opening 221, and the inner wall of the avoiding opening 22 comprises a bottom edge 222 opposite the opening 221 and side edges 223 on both sides of the bottom edge 222.

The bottom edge 222 is arranged obliquely, and the air is subjected to a vertical extrusion force. When the air slides along the bottom edge 222, the flow direction of the air extruded upward and downward changes to an oblique direction upward and toward the opening 221, so as to discharge the air and reduce the impact force of the air on the substrate to be lifted upward, thereby ensuring the stability of the substrate.

[0036] Referring to Figs. 1-3 A plurality of exhaust holes 23 are formed on the rack 2, one end of the exhaust hole 23 is located in the inner wall of the avoiding opening 22, and the other end is located on the upper surface of the rack 2 and is arranged in a staggered manner with the substrate. A communication groove 24 is formed on the upper surface of the rack 2 along the bottom edge 222 and the side edge 223, and one end of the communication groove 24 is located at the end of one side edge 223 close to the opening 221, and the other end is located at the end of the other side edge 223 close to the opening 221. The exhaust hole 23 and the communication groove 24 cooperate to increase the air discharge path and increase the air discharge flow, thereby improving the air discharge effect and ensuring the stability of the substrate.

[0037] Referring to Figs. 1-3 The anti-floating plate 3 corresponding to the detection groove 21 is slidably connected to the upper surface of the rack 2, and the anti-floating plate 3 is slidably connected to the edge of the detection groove 21 and located above the detection groove 21. A plurality of protrusions 32 are arranged on the lower surface of the anti-floating plate 3. The anti-floating plate 3 is used to press on the upper surface of the substrate, thereby further improving the stability of the substrate.

[0038] Referring to Figs. 1-3 An inclined sliding groove 25 is formed on the rack 2 from top to bottom, and the lower end of the sliding groove 25 is close to the detection groove 21, and the upper end of the sliding groove 25 is away from the detection groove 21. A sliding rod 31 is slidably connected in the sliding groove 25, the upper end of the sliding rod 31 is fixedly connected with the anti-floating plate 3, and the lower end of the sliding rod 31 is fixedly connected with the floating plate 4. When the anti-floating plate 3 is located at the lowermost position, the edge of the anti-floating plate 3 is located in the detection groove 21, and when the anti-floating plate 3 is located at the uppermost position, the edge of the anti-floating plate 3 is not in the detection groove 21.

The maximum buoyancy that the buoyancy plate 4 receives in water is F2, and the sum of the buoyancies of F1 and F2 is F3. The gravity of the buoyancy plate 4 is G2, and the sum of the gravities of G1 and G2 is G3. The elastic force of the abutting spring 6 is F4, and the gravity of the base material is G4. The following conditions are satisfied: F1>G1; F2>G3; F3>G3+F4; and F3+F4

[0041] The implementation principle of the work tool for the ultrasonic scanning water tank of the sheet base material is as follows: the base material is installed in front of the rack 2, the rack 2 is located above the water surface, but the buoyancy plate 4 is completely immersed in water, and the upper end of the abutting rod 5 extends out of the abutting hole 26 under the action of the abutting spring 6. Since F2>G3, the buoyancy plate 4 and the anti-floating plate 3 are affected by the buoyancy and move upward, and the anti-floating plate 3 completely releases the detection groove 21 to facilitate the installation of the base material.

[0042] The base material is installed in the detection groove 21, and since F3+F4

[0043] The base material is immersed in water, and after the rack 2 drives the base material to be immersed in water, since F3>G3+F4, at this time, the buoyancy plate 4 and the anti-floating plate 3 are simultaneously subjected to the maximum buoyancy to overcome the spring elastic force to slide upward, so that the anti-floating plate 3 is separated from the base material, and the surface of the base material is completely exposed to facilitate the scanning of the ultrasonic probe.
