Description

Technical Field

[0001] The invention belongs to the field of ultrasonic detection, and in particular relates to a tellurium copper ingot casting internal defect detection device. Background Art

[0002] Tellurium copper ingot is an alloy material composed of tellurium and copper. According to the different tellurium contents, tellurium copper alloys can be divided into many types. For example, tellurium copper containing 0.4% to 0.7% tellurium has good cutting performance, while copper telluride containing 50% tellurium and 50% copper is used as an intermediate alloy. Tellurium copper alloy has high thermal conductivity and electrical conductivity, and its excellent physical properties make it widely used in the fields of high electrical conductivity and high thermal conductivity.

[0003] The casting process of tellurium copper ingots includes the steps of preparing raw materials, mixed smelting, copper-tellurium separation and refining. Through reasonable smelting process and refining treatment, high-purity tellurium copper alloy products can be obtained. In the casting process of tellurium copper ingots, due to factors such as the purity of raw materials and the uniformity of mixed smelting, the produced tellurium copper ingots may have internal defects such as bubbles and impurities, which will affect the performance of tellurium copper ingots. Therefore, after the tellurium copper ingots are produced, they need to be tested to determine whether they are qualified.

[0004] Existing detection equipment is usually a flaw detector, which transmits ultrasonic waves to the tellurium copper ingot and receives ultrasonic waves reflected from the inside of the tellurium copper ingot. By judging the frequency and time of the reflected ultrasonic waves, the position and shape of the defects in the tellurium copper ingot can be obtained. The existing detection method is that the staff puts the tellurium copper ingot on the detection bed, and then uses the probe of the flaw detector to detect the end of the tellurium copper ingot. However, since the diameter of the tellurium copper ingot is usually larger than the diameter of the probe, the staff needs to repeatedly move the position of the probe to conduct a comprehensive inspection of the tellurium copper ingot. Since the staff's arm holding the probe will be suspended in the air, after working for a long time, the staff's arm will become tired and stiff, which is not conducive to long-term work. In addition, since the staff cannot accurately control the moving distance of the probe, the overlapping area of ​​the probe's moving trajectory will increase, which will extend the detection time and reduce the detection efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a detection driving mechanism. After the probe is installed on the detection driving mechanism, the detection driving mechanism can drive the probe to move in the horizontal direction and the vertical direction, so that the motion trajectory of the probe can cover the entire end surface of the tellurium copper ingot.

Therefore, the detection drive mechanism 8 also includes a horizontal drive component and a vertical drive component, and the horizontal drive component and the vertical drive component are both installed on the installation box 810. The output end of the horizontal drive component is transmission-connected to the sliding sleeve 85, and the output end of the vertical drive component is transmission-connected to the lifting block 84.

[0036] like Figure 1-Figure 2 and Figure 5-Figure 7 As shown, a tellurium copper ingot casting internal defect detection device provided by the present invention is provided. When the tellurium copper ingot is detected by the device disclosed in the above embodiment, the staff is still required to load and unload the tellurium copper ingot, and the workload of the staff is still very large.

Under the action of the hypotenuse of the movable support block 422, the movable support block 422 squeezes the tellurium copper ingot to the top of the fixed support block 421, and is blocked by the semi-enclosing plate 6, thereby preventing the tellurium copper ingot from falling; During the inspection, the tellurium copper ingot can be driven to rise to any position below the center plane of the discharge port 12 by the support plate 3, and the detection drive mechanism 8 can drive the probe 16 to inspect the tellurium copper ingot; after the inspection is completed, the first telescopic rod 11 continues to drive the support plate 3 to rise, and the pin 427 moves to the top of the turntable 426, then the distance between the movable support block 422 and the top of the support plate 3 reaches the maximum, at this time, the tellurium copper ingot just moves to the side of the discharge port 12, such as Figure 7 As shown, under the action of the inclined edge of the movable support block 422 , the tellurium copper ingot rolls down from the discharge port 12 .

[0040] like Figure 1-Figure 2 and Figure 5-Figure 9As shown in the figure, a tellurium copper ingot casting internal defect detection device provided by the present invention is provided. When the support plate 3 drives the tellurium copper ingot to rise, the movable support block 422 can lift the tellurium copper ingot, and the movable support block 422 will squeeze the tellurium copper ingot onto the semi-enclosing plate 6. Since the central axis of the tellurium copper ingot deviates from the vertical central plane of the support plate 3, the tellurium copper ingot is not easy to be positioned by the probe 16. Moreover, since the tellurium copper ingot contacts the semi-enclosing plate 6, the semi-enclosing plate 6 will block the probe 16, so that the detection of the tellurium copper ingot by the probe 16 may be incomplete, reducing The detection effect of the flaw detector 9 on the tellurium copper ingot is reduced. Therefore, in this embodiment, a material blocking assembly 7 is installed on the limit plate 14, and the material blocking assembly 7 includes a third slide groove 73 opened on the limit plate 14, one end of the third slide groove 73 passes through the detection bed 2 and is connected with the discharge port 12, and a material blocking plate 71 is slidably installed inside the third slide groove 73, and a first compression spring 72 is connected between the material blocking plate 71 and the limit plate 14. Initially, the material blocking plate 71 closes the discharge port 12.

[0041] After the tellurium copper ingot is raised to the discharge port 12, the tellurium copper ingot will not fall due to the blocking of the material blocking plate 71, and then the support plate 3 continues to drive the tellurium copper ingot to rise until the movable support block 422 returns to the initial position. At this time, the tellurium copper ingot is located between the movable support block 422 and the fixed support block 421, and the central axis of the tellurium copper ingot coincides with the vertical central plane of the support plate 3, so that a gap is left between the tellurium copper ingot and the side of the semi-enclosing plate 6, which is convenient for the probe 16 to detect the tellurium copper ingot; After the inspection is completed, the first telescopic rod 11 drives the supporting plate 3 to descend, and the supporting plate 3 drives the tellurium copper ingot to descend. When the tellurium copper ingot descends to the discharge port 12, the baffle plate 71 is pulled downward, and then the discharge port 12 is opened. Then, the tellurium copper ingot is discharged from the discharge port 12, and then the supporting plate 3 continues to descend and returns to its original position. The tellurium copper ingot on the upper hopper 1 will automatically roll down to between the fixed support block 421 and the movable support block 422, and the baffle plate 71 is released at the same time. Under the action of the first compression spring 72, the baffle plate 71 closes the discharge port 12 again for the next operation.

[0042] like Figure 1-Figure 2 and Figure 5-Figure 9 As shown, a tellurium copper ingot casting internal defect detection device provided by the present invention is provided. In order to realize the automation of the device and reduce manual participation, in this embodiment, the blocking assembly 7 also includes a release mechanism 13, and the release mechanism 13 includes a first fixed box 132, and the first fixed box 132 is fixedly connected to the bottom of the blocking plate 71 through a connecting rod 131. A pull tab 134 is slidably connected inside the first fixed box 132, and a first inclined surface is provided at the bottom of one end of the pull tab 134 extending out of the first fixed box 132, and a second compression spring 133 is connected between the pull tab 134 and the first fixed box 132; The unlocking mechanism 13 also includes a second fixed box 139 fixedly mounted on the side of the supporting plate 3, a slider 137 is slidably connected inside the second fixed box 139, a third compression spring 138 is connected between the slider 137 and the second fixed box 139, a tongue 136 and a pressure block 1310 are fixedly connected to the side of the slider 137 close to the pull tongue 134, a second inclined surface is provided on the top of one end of the tongue 136, the tongue 136 and the pull tongue 134 are staggered in the vertical plane, a third inclined surface is provided on the bottom of one end of the pressure block 1310, a release block 135 is fixedly connected to the side of the limiting plate 14 close to the second fixed box 139, and fourth inclined surfaces are provided at both ends of the release block 135; In order to prevent the pressure block 1310 from squeezing the pull tab 134, causing the pull tab 136 and the pull tab 134 to fail to engage, the distance between the bottom of the pull tab 136 and the top of the pressure block 1310 is greater than the thickness of the pull tab 134; Initially, the distance from the top of the limit release block 135 to the bottom of the pull tongue 134 is greater than the width of the feed opening 12, and smaller than the distance from the bottom of the baffle plate 71 to the bottom of the third slide groove 73, so that the support plate 3 can smoothly open the feed opening 12 through the release mechanism 13 and restore the baffle plate 71 again.

[0043] When the support plate 3 drives the tellurium copper ingot to rise, the support plate 3 also drives the second fixed box 139 to rise. When the second fixed box 139 drives the push tongue 136 to meet the pull tongue 134, under the action of the first inclined surface and the second inclined surface, the push tongue 136 and the pull tongue 134 are squeezed and staggered against each other, so that the second fixed box 139 can drive the push tongue 136 to continue to rise, and the pull tongue 134 is prevented from affecting the movement of the support plate 3. When the support plate 3 descends, the support plate 3 drives the second fixed box 139 and the tongue 136 to descend. When the bottom of the tongue 136 contacts the top of the pull tongue 134, the support plate 3 drives the pull tongue 134 to descend through the tongue 136. The pull tongue 134 drives the baffle plate 71 to descend through the first fixed box 132 and the connecting rod 131, thereby opening the discharge port 12 so that the tellurium copper ingot on the support plate 3 can be discharged through the discharge port 12. As the supporting plate 3 drives the tongue 136 to continue to descend, the pressure block 1310 will encounter the limit release block 135, and the limit release block 135 will squeeze the pressure block 1310 to retract into the second fixed box 139. The pressure block 1310 drives the slider 137 and the tongue 136 to retract into the second fixed box 139, and the tongue 136 and the pull tongue 134 are disengaged. Under the action of the first compression spring 72, the baffle plate 71 rebounds and closes the discharge port 12 again, and the pressure block 1310 and the tongue 136 will pass the limit release block 135 and continue to move downward until the supporting plate 3 returns to its original position.

[0044] like Figure 1 and Figure 7 As shown, a tellurium copper ingot casting internal defect detection device provided by the present invention, after the tellurium copper ingot is inspected, the flaw detector 9 generally displays the shape and position of the bubbles and impurities inside the tellurium copper ingot, so that the staff can perform post-processing on the tellurium copper ingot, but the shape and position are relative to the overall length of the tellurium copper ingot. After the inspection is completed, the staff is required to measure the length of the tellurium copper ingot again and mark the positions of the bubbles and impurities, which is a cumbersome operation. In this embodiment, a positioning scale line 10 is provided on the side of the semi-enclosure 6, and the length of the tellurium copper ingot can be intuitively measured through the positioning scale line 10, and the positions of the bubbles and impurities can be marked on the tellurium copper ingot according to the data displayed on the flaw detector 9, which is convenient for post-processing without the need for the staff to measure it manually.

[0045] like Figure 1-Figure 2 , Figure 5 and Figure 10-11 As shown, it is a tellurium copper ingot casting internal defect detection device provided by the present invention. When loading, when the end of the tellurium copper ingot is not aligned with the zero scale line of the positioning scale line 10, the staff is often required to calculate the relative position of the tellurium copper ingot according to the positioning scale line 10, and then mark it, which wastes a lot of time. Therefore, in this embodiment, the zero scale line of the positioning scale line 10 is aligned with the corner of the side of the semi-enclosure plate 6 opposite to the detection drive mechanism 8, and a driving positioning mechanism 5 is installed on the supporting plate 3, and the driving positioning mechanism 5 includes a plurality of transmission components, and the transmission component includes a mounting groove 52 opened on the top of the supporting plate 3, and the two inner side walls of the mounting groove 52 are each provided with a second slide groove 56, and a mounting seat 54 is slidably connected between the two second slide grooves 56, and a transmission wheel 53 is rotatably connected to the mounting seat 54, and a second telescopic rod 55 is fixedly installed inside the mounting groove 52, and the movable end of the second telescopic rod 55 is fixedly connected to the bottom of the mounting seat 54; In order to drive the transmission wheel 53 to rotate, the driving positioning mechanism 5 also includes a second installation cavity 58 opened inside the support plate 3, the second installation cavity 58 and the plurality of installation seats 54 are all connected, a first motor 51 is fixedly installed on the support plate 3, one end of the first motor 51 extending into the second installation cavity 58 is fixedly connected to a driving sprocket 511, and one end of the plurality of transmission wheels 53 extending into the second installation cavity 58 is fixedly connected to a driven sprocket 57, and a chain 512 is transmission-connected between the plurality of driven sprockets 57 and the driving sprocket 511; In order not to affect the lifting and lowering of the transmission wheel 53, the driving positioning mechanism 5 also includes a tensioning assembly, which includes an elastic tensioning rod 59 and a tensioning sprocket 510. The elastic tensioning rod 59 is installed in the second installation cavity 58, and the tensioning sprocket 510 is rotatably installed on the movable end of the elastic tensioning rod 59. The middle part of the chain 512 is transmission-connected to the tensioning sprocket 510.

[0046] After the tellurium copper ingot is raised to be level with the axis of the probe 16 through the supporting plate 3, the second telescopic rod 55 is started, and the second telescopic rod 55 drives the transmission wheel 53 to rise through the mounting seat 54, and the transmission wheel 53 lifts the tellurium copper ingot and makes the tellurium copper ingot separate from the unloading mechanism 4. At the same time, the chain 512 squeezes the elastic tensioning rod 59 through the tensioning sprocket 510, thereby avoiding affecting the lifting and lowering of the transmission wheel 53. Then, the first motor 51 is started, and the first motor 51 drives the driving sprocket 511 to rotate. The driving sprocket 511 drives multiple driven sprockets 57 to rotate through the chain 512. The driven sprocket 57 drives the transmission wheel 53 to rotate. The transmission wheel 53 drives the tellurium copper ingot to move horizontally, so that the end of the tellurium copper ingot abuts against the side of the semi-enclosure 6 opposite to the probe 16, so as to quickly locate the defect of the tellurium copper ingot. Then, the second telescopic rod 55 drives the transmission wheel 53 and the tellurium copper ingot to descend, and makes the tellurium copper ingot fall onto the unloading mechanism 4 again, so as to facilitate the detection of it by the probe 16.

[0047] like Figure 1-Figure 2 , Figure 5 and Figure 10-11 As shown, a tellurium copper ingot casting internal defect detection device provided by the present invention, in this embodiment, the elastic tensioning rod 59 includes a fixed sleeve 591 fixedly connected to the inside of the second mounting cavity 58, one end of the fixed sleeve 591 is slidably connected to a movable rod 592, a fifth compression spring is connected between the movable rod 592 and the fixed sleeve 591, one end of the movable rod 592 is fixedly connected to a mounting bracket 593, and the tensioning sprocket 510 is rotatably mounted on the mounting bracket 593.

[0048] Directions: Place multiple tellurium copper ingots on the upper hopper 1, the tellurium copper ingots will roll onto the detection bed 2 and be blocked by the half-enclosing plate 6, and then the last tellurium copper ingot will fall between the movable support block 422 and the fixed support block 421 on the support plate 3, and then the first telescopic rod 11 drives the support plate 3 to rise, and the support plate 3 drives the tellurium copper ingot to rise through the unloading mechanism 4, and moves the tellurium copper ingot to a position where its axis coincides with the axis of the probe 16; Then, the first motor 51 is started, and the first motor 51 drives the driving sprocket 511 to rotate. The driving sprocket 511 drives a plurality of driven sprockets 57 to rotate through the chain 512. The driven sprocket 57 drives the transmission wheel 53 to rotate. The transmission wheel 53 drives the tellurium copper ingot to move horizontally, so that the end of the tellurium copper ingot abuts against the side of the semi-enclosure plate 6 opposite to the probe 16, so as to facilitate the rapid positioning of the tellurium copper ingot. Then, the second telescopic rod 55 drives the transmission wheel 53 and the tellurium copper ingot to descend, and makes the tellurium copper ingot fall onto the unloading mechanism 4 again. The third telescopic rod 82 is started, and the third telescopic rod 82 drives the probe 16 to approach the end of the tellurium copper ingot through the mounting block 83, and the probe 16 contacts the end of the tellurium copper ingot. Then the second motor 88 drives the screw 87 to rotate, and the screw 87 drives the sliding sleeve 85 and the lifting block 84 to move horizontally. The lifting block 84 drives the third telescopic rod 82, the mounting block 83 and the probe 16 to move horizontally, so that the probe 16 covers the end of the tellurium copper ingot laterally. At the same time, the fourth telescopic rod 89 drives the lifting block 84 to move up and down through the sliding plate 86, and the lifting block 84 drives the third telescopic rod 82, the mounting block 83 and the probe 16 to move up and down, so that the probe 16 covers the end of the tellurium copper ingot vertically, so that the probe 16 can detect the entire end of the tellurium copper ingot. By observing the data on the flaw detector 9 and cooperating with the positioning scale line 10, the positions of bubbles and impurities in the tellurium copper ingot can be quickly marked; Then the first telescopic rod 11 drives the supporting plate 3 to descend, and under the action of the supporting rack 41, the movable supporting block 422 drives the tellurium copper ingot to rise, and under the action of the hypotenuse of the movable supporting block 422, the movable supporting block 422 squeezes the tellurium copper ingot to the side of the semi-enclosing plate 6, and at the same time, the supporting plate 3 drives the pull tongue 134 to descend through the push tongue 136, and the pull tongue 134 drives the baffle plate 71 to descend through the first fixing box 132 and the connecting rod 131, so as to open the discharge port 12. When the discharge port 12 is fully opened, the movable supporting block 422 drives the tellurium copper ingot to move to the discharge port 12, and the tellurium copper ingot rolls from the discharge port 12 to the discharge hopper 15 for discharge; Then the first telescopic rod 11 drives the supporting plate 3 to continue to descend, and under the action of the supporting rack 41, the movable supporting block 422 retracts into the first mounting cavity 44 again. At the same time, when the pressure block 1310 encounters the limit release block 135, the limit release block 135 will squeeze the pressure block 1310 and the tongue 136 to retract into the second fixed box 139, and the tongue 136 and the pull tongue 134 will disengage. Under the action of the first compression spring 72, the baffle plate 71 rebounds and closes the feed opening 12 again. Then the supporting plate 3 descends to the position where the movable supporting block 422 is flush with the surface of the detection bed 2, and the tellurium copper ingot on the detection bed 2 will roll between the movable supporting block 422 and the fixed supporting block 421, so that the tellurium copper ingot can be detected again. Such a cycle can realize continuous detection of tellurium copper ingots, which is simpler and more labor-saving to use.
