TECHNICAL FIELD

[0001] The application relates to the technical field of ultrasonic scanning equipment, in particular to an ultrasonic scanning clamping mechanism capable of automatically removing water. BACKGROUND

[0002] SAT (ultrasonic scanning microscope) detection is a machine table for detecting ultrasonic signals by using pure water as a medium and by detecting the reflection rate and energy difference of high-frequency ultrasonic waves and materials with different densities. The ultrasonic scanning microscope is a general manufacturing equipment.

[0003] The ultrasonic scanning microscope has a wide application range and can be used for scanning and analyzing various materials and is widely applied to various fields, such as food industrialized processing and intelligent manufacturing equipment industry. At present, a manipulator is usually used to clamp and transport a sample.

[0004] During the ultrasonic scanning process, the manipulator clamps and transports a sample to be scanned and places the sample into a water tank, an ultrasonic probe scans the sample by using water as a medium, after the scanning is completed, the manipulator takes out the sample from the water tank, removes water from the sample by using a drying device, finally, the manipulator takes out the dried sample, and finally outputs the sample.

[0005] The sample needs to go through the processes of entering water, exiting water and drying in the air during the scanning process, therefore, the manipulator needs to be in contact with water to take and place the sample by extending into the water tank. The manipulator will inevitably be wet. When the manipulator clamps the sample after drying, the sample will be wetted again by the manipulator, thereby affecting the drying effect of the sample. SUMMARY

[0006] In order to ensure the drying effect of the sample, the application provides an ultrasonic scanning clamping mechanism capable of automatically removing water.

[0007] The ultrasonic scanning clamping mechanism provided by the application adopts the following technical scheme: The ultrasonic scanning clamping mechanism capable of automatically removing water comprises a clamping jaw, the clamping jaw comprises a base plate, a pair of side jaws for clamping two sides of a base material are horizontally and slidably connected to the base plate, a plurality of water absorption holes are formed in the side of each side jaw that faces the other side jaw, a water absorption channel is formed in each side jaw, one end of the water absorption channel is in communication with the water absorption hole, and the other end of the water absorption channel is located at the upper end of the side jaw, a negative pressure pipe is connected to the upper side of the end portion of the base plate, and the negative pressure pipe is in communication with the upper end of the water absorption channel when the pair of side jaws are moved away from each other to the farthest distance.

[0008] By adopting the above technical scheme, the pair of side claws move towards each other, and the two side claws clamp and transport the sample. After the sample is released, the two side claws move away from each other to the farthest end and reset, at this time, the negative pressure pipe is opposite and communicates with the upper end of the water suction channel, the negative pressure generated in the negative pressure pipe sucks the water droplets on the outer wall of the side claw through the water suction hole, thereby ensuring the dryness of the surface of the side claw. When the side claw clamps the sample again next time, the surface of the side claw is relatively dry, thereby avoiding bringing water to the sample again, and affecting the dryness of the sample.

[0011] As a preferred, the lower end of the side plate is fixed with a horizontally arranged side frame, and the contact plate is horizontally slidingly connected in the side frame.

[0012] By adopting the above technical scheme, the contact plate slides in the side frame, the side frame limits and guides the contact plate, and the stability of the movement of the contact plate is improved.

[0013] As a preferred, the side frame and the side plate are hollowly arranged, and the water suction channel is formed in the inside, and a plurality of negative pressure suction holes communicating with the water suction channel are arranged on the inner wall of the side frame.

[0014] By adopting the above technical scheme, when the side claw moves to the end of the substrate, the negative pressure pipe communicates with the water suction channel. When the negative pressure suction force is generated in the water suction channel, on the one hand, the water on the surface of the contact plate is sucked into the water suction channel through the water suction hole, and on the other hand, the contact plate is gradually shrunk in the side frame under the suction force, and the negative pressure suction holes in the inner wall of the side frame also suck the water on the outer wall of the contact plate, thereby improving the water absorption effect of the outer surface of the contact plate and improving the dryness of the surface of the contact plate.

[0015] As a preferred, a support mesh plate opposite to the contact plate is fixed in the side plate, a plurality of anti-blocking rods opposite to the water suction holes are fixed on the support mesh plate, and the diameter of the anti-blocking rod is smaller than the diameter of the water suction hole.

[0016] By adopting the above technical scheme, the contact plate moves to the support mesh plate under the negative pressure suction force until the anti-blocking rod is inserted into the water suction hole, the anti-blocking rod dredges the water suction hole, and prevents the water suction hole from being blocked.

[0017] As a preferred, a plurality of suction nozzles are vertically arranged on the substrate.

[0018] By adopting the technical scheme, the adsorption nozzle and the side claw cooperate with each other to clamp and transport the sample, and the stability of clamping is improved.

[0019] Preferably, the water absorption holes are arranged in the shape of a circular truncated cone, and the diameter of one end of the water absorption holes facing each other is greater than the diameter of the other end.

[0023] In summary, the present application has the following beneficial technical effects: The negative pressure generated in the negative pressure pipe can remove the water droplets on the outer wall of the side claw through the water absorption holes, ensure the dryness of the surface of the side claw, and avoid bringing water to the sample again, thereby affecting the dryness of the sample.

DETAILED DESCRIPTION

[0026] The present application will be further described in detail below in combination with all the drawings.

[0027] EMBODIMENT The embodiment of the present application discloses an automatic water removal clamping mechanism for ultrasonic scanning, which refers to Figures 1 to 4, including gantry 5 and installed on the gantry 5 jaw 1. Jaw 1 includes a base plate 2, a pair of base plate 2 on the horizontal sliding connection for clamping both sides of the side claw 3, two side claws 3 when the sample is clamped, two side claws 3 or back movement when the sample is released. The lower surface of the base plate 2 is vertically provided with a plurality of suction nozzles 37. Suction nozzle 37 and side claw 3 cooperate to clamp the sample, improve the stability of clamping.

[0028] Referring to Figures 1 to 4 , side claw 3 includes a vertically arranged side plate 32 connected to the base plate 2 horizontally sliding and a contact plate 34 horizontally slidingly connected below the side plate 32. The side plate 32 is fixed to the side frame 33 on the side facing each other at the lower end, and the contact plate 34 is horizontally slidingly connected in the side frame 33. The side plate 32 and the side frame 33 are hollowly provided with a water suction channel 31, and the upper end of the side claw 3 is provided with a suction port connected with the water suction channel 31.

[0029] Referring to Figures 1 to 4 , a plurality of circular truncated cone-shaped water suction holes 341 are formed on the contact plate 34, and the diameter of the end facing each other of the water suction hole 341 is larger than the diameter of the other end. The water suction hole 341 is in communication with the water suction channel 31. After the contact plate 34 is in contact with the sample with water, water droplets are easily left on the surface of the contact plate 34. In order to prevent the contact plate 34 from being secondarily contaminated by the dried sample, a negative pressure suction force is generated in the water suction channel 31, and the water droplets on the surface of the contact plate 34 are sucked into the water suction channel 31 through the water suction hole 341, thereby ensuring the dryness of the surface of the contact plate 34.

[0030] Referring to Figures 1 to 4 , a plurality of drainage grooves 342 are formed on the surface of the contact plate 34, and the water suction hole 341 is in communication with the drainage groove 342. The drainage groove 342 covers the surface of the contact plate 34, and the water suction hole 341 can absorb and remove the water on the entire surface of the contact plate 34 through the drainage groove 342, which has a larger removal range and better water removal effect.

[0031] Referring to Figures 1 to 4 , a plurality of negative pressure suction holes 331 are formed on the inner wall of the side frame 33 and are in communication with the water suction channel 31. When the negative pressure suction force is generated in the water suction channel 31, on the one hand, the water on the surface of the contact plate 34 is sucked into the water suction channel 31 through the water suction hole 341, and on the other hand, the contact plate 34 is gradually shrunk in the side frame 33 due to the suction force, and the negative pressure suction hole 331 on the inner wall of the side frame 33 also absorbs the water on the outer wall of the contact plate 34, thereby improving the absorption effect of the water on the outer surface of the contact plate 34 and improving the dryness of the surface of the contact plate 34.

[0032] Referring to Figures 1 to 4The support net plate 36 is fixed in the side plate 32 and opposite to the contact plate 34, the anti-blocking rod 361 is fixed on the support net plate 36 and opposite to the water suction hole 341, and the diameter of the anti-blocking rod 361 is smaller than that of the water suction hole 341. The contact plate 34 is moved to the support net plate 36 direction by the negative pressure suction force until the anti-blocking rod 361 is inserted into the water suction hole 341, the anti-blocking rod 361 dredges the water suction hole 341 and prevents the water suction hole 341 from being blocked.

[0033] With reference to Figures 1 to 4 The buffer spring 35 is connected between the contact plate 34 and the side plate 32 and fixed on the inner wall of the side claw 3 through the support net plate 36. When the side plate 32 clamps the sample, the contact plate 34 contacts the sample and buffers and protects the sample.

[0034] With reference to Figures 1 to 4 The negative pressure pipe 4 is connected to the upper end of the water suction channel 31 when the pair of side claws 3 are moved away from each other to the farthest distance. The pair of side claws 3 are moved towards each other to clamp and transport the sample. After the sample is released, the pair of side claws 3 are moved away from each other to the farthest end to reset, at this time, the negative pressure pipe 4 is opposite to and communicated with the upper end of the water suction channel 31, the negative pressure pipe 4 generates negative pressure to suck the water droplets on the outer wall of the side claw 3 through the water suction hole 341, so as to ensure the dryness of the surface of the side claw 3.

[0035] The implementation principle of the automatic water removal ultrasonic scanning clamping mechanism is that the pair of side claws 3 are moved towards each other to clamp and fix the sample, the side claws 3 are moved away from each other after the sample is released, the side claws 3 are moved to the end of the base plate 2, and the negative pressure pipe 4 sucks the water on the surface of the contact plate 34 to ensure the dryness of the surface of the contact plate 34.

[0036] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the structure, shape and principle of the present application should be covered in the protection scope of the present application.
