Description

Technical Field

[0001] The present invention relates to the technical field of target material quality detection, and in particular to a planar target material density measurement system and a measurement method. Background Art

[0002] It is one of the basic experimental tools for material research. The planar target is connected to the sputtering equipment by means of threads, etc., and the film layer is attached to the substrate by sputtering under vacuum conditions. Then the film is processed by various means (such as etching) to meet different needs. The density of the target is an important parameter in the target quality detection.

[0003] At present, the density of flat targets after sintering needs to be measured manually by placing them in a water tank, using a scale to measure the wet weight and dry weight, and then manually recording the relevant data to convert it into the final density value. This is time-consuming, labor-intensive and inaccurate. In addition, the newly calcined products are rectangular plate-shaped blanks that need to be tested for density. The product characteristics are large flatness ratio, high brittleness, large size and heavy weight.

[0044] In an optional embodiment, the storage rack 1 needs to be fed into the feeding device 3 through the loading seat 2 to realize automatic loading of the planar target material. In this embodiment, the storage rack 1 is provided with a plurality of placement slots for storing the planar target materials, and the lower part of the placement slot is provided with a through hole for driving the transportation of the planar target materials.

[0045] For details, please refer to Figure 3 and Figure 4As shown, the loading seat 2 includes a loading frame 21, on which a plurality of screw lifts 22 are fixedly mounted, and the plurality of screw lifts 22 are connected to each other by a screw drive shaft 23, and a driving hand wheel 24 is fixedly mounted at one end of the screw drive shaft 23, and the driving hand wheel 24 is used to drive the screw drive shaft 23 to rotate, thereby driving the screw in the screw lift 22 to move up and down, so as to realize the lifting and lowering adjustment; at the same time, a loading support 27 is arranged above the loading frame 21, and the lower end of the loading support 27 is connected to the screw lift 2 2 is connected to the lifting screw rod, and a plurality of feeding rollers 28 are rotatably installed on the feeding support 27.

The upper end of the feeding guide rod 26 is fixedly connected to the lower end of the feeding support 27. The guiding cooperation of the feeding guide sleeve 25 and the feeding guide rod 26 is used to guide the lifting and lowering movement of the feeding support 27, so as to ensure that the lifting and lowering of the feeding support 27 remains stable.

[0046] In addition, the planar target material needs to be pushed in and out of the storage rack 1. During the process of the target material being pushed in and out, the target material needs to be supported. Therefore, a supporting side plate 29 is fixedly provided on one side of the loading rack 21, and a supporting roller 291 is rotatably installed on the supporting side plate 29 to support the target material being pushed in and out by the supporting roller 291.

[0047] At the same time, it is also necessary to push the storage rack 1 into the feeding device 3, so a plurality of loading guide rails 213 for supporting the sliding of the storage rack 1 are fixedly provided at the upper end of the loading rack 21, and a loading side plate 212 for limiting the storage rack 1 is fixedly provided on the side of the loading guide rail 213 away from the feeding device 3 to ensure the accuracy of the placement of the storage rack 1 on the loading seat 2.

[0048] In an optional embodiment, the feeding device 3 needs to receive the storage rack 1 pushed by the loading seat 2, and at the same time feed the planar target material stored in the storage rack 1 into the measuring rack 4 for density measurement.

[0049] For details, please refer to Figure 5 and Figure 6As shown, the feeding device 3 includes a feeding frame 31, on which a plurality of shift guide rails 32 are fixedly arranged, and a feeding slide 33 is slidably connected to the shift guide rails 32, wherein the feeding slide 33 is used to receive the storage frame 1, and a feeding guide rail 34 is arranged on the feeding slide 33 to cooperate with the loading guide rail 213, and the loading guide rail 213 and the feeding guide rail 34 are connected to form a straight guide rail to guide the translational sliding of the storage frame 1. At the same time, in order to drive the feeding slide 33 to move, a feeding screw module 35 is fixedly installed on the feeding frame 31, and a screw connecting plate 36 is fixedly connected to the movable end of the feeding screw module 35, which is fixedly connected to the feeding slide 33 through the screw connecting plate 36 to drive the movement of the feeding slide 33, thereby adjusting the position of the storage frame 1, so that different planar targets are aligned with the measuring frame 4 for loading and transportation.

[0050] The feeding slide 33 is used to receive the storage rack 1, and a mechanism for conveying the planar target material is also required. Specifically, a plurality of feeding brackets 39 are arranged above the feeding rack 31, a feeding shaft 310 is rotatably mounted on the feeding bracket 39, a feeding roller 311 is fixedly mounted on the feeding shaft 310, and a plurality of push cylinders 37 for driving the feeding bracket 39 to move up and down are fixedly mounted on the feeding rack 31. The output end of the push cylinder 37 is fixedly connected to the feeding bracket 39, and the feeding rack 31 slides through the feeding bracket 39. It is connected with a plurality of pushing guide rods 38, the upper ends of which are fixedly connected to the feeding bracket 39, and the feeding bracket 39 is driven to move up and down by the pushing cylinder 37. When it is necessary to drive the storage rack 1 to move, the pushing cylinder 37 drives the feeding bracket 39 to move downward, so that the storage rack 1 can move normally. After aligning the planar target material on the storage rack 1 with the feeding roller 311, the pushing cylinder 37 drives the feeding bracket 39 to move upward, and the planar target material is lifted up by the feeding roller 311 and then sent into the measuring rack 4.

[0051] Since the material storage rack 1 needs to be fed into the feeding device 3 through the loading seat 2, it is necessary to ensure that the loading seat 2 and the feeding device 3 remain relatively stable and accurately positioned, thereby ensuring the accurate docking between the feeding guide rail 34 and the loading guide rail 213. Specifically, a plurality of positioning slots 316 are provided on the side of the feeding rack 31 close to the loading rack 21, and a connecting sleeve 211 that matches the positioning slot 316 is provided on the side of the loading rack 21 close to the feeding rack 31. The connecting sleeve 211 is fixedly mounted on the loading rack 21 through the positioning side plate 210, thereby achieving the accuracy of the docking between the loading seat 2 and the feeding device 3.

[0052] Furthermore, the loading seat 2 and the feeding device 3 are positioned and connected by the cooperation of the positioning groove seat 316 and the connecting sleeve 211. A positioning cylinder 312 is fixedly installed on the feeding frame 31. The output end of the positioning cylinder 312 is fixedly connected to a rotating seat 313. A limiting connecting rod 314 is connected to the rotating seat 313. A limiting pressure block 315 is fixedly connected to the limiting connecting rod 314. The limiting connecting rod 314 drives the limiting connecting rod 314 and the limiting pressure block 315 to move horizontally through the positioning cylinder 312. The supporting legs of the loading frame 21 are fixedly clamped by the limiting pressure block 315 to ensure the stability of the alignment connection between the loading seat 2 and the feeding device 3.

[0053] In an alternative embodiment, see Figure 8 and Fig.16 As shown, a conveying roller structure 8 is provided in the measuring frame 4, and the conveying roller structure 8 is used to horizontally convey the planar target material;

[0054] The conveying roller structure 8 includes a conveying guide rail 81 and a conveying cylinder 83 fixedly mounted on the measuring frame 4, a conveying slide 82 being slidably connected to the conveying guide rail 81, an output end of the conveying cylinder 83 being fixedly connected to the conveying slide 82 via a conveying connecting plate 84, a plurality of roller shafts 89 being rotatably mounted on the conveying slide 82, a conveying roller 811 being fixedly mounted on the roller shaft 89, and a conveying motor 85 for driving the roller shaft 89 to rotate being fixedly mounted on the conveying slide 82.

[0055] It should be noted that, since there are several groups of roller shafts 89, in order to ensure the synchronous driving of several groups of roller shafts 89, a driving mechanism is required to realize the synchronous driving, which is specifically that a transmission support 86 is fixedly arranged on the transmission slide 82, a transmission shaft 87 is rotatably mounted on the transmission support 86, and several driving gears 88 are fixedly mounted on the transmission shaft 87. The number and position of the several driving gears 88 correspond to the roller shaft 89. At the same time, a driven gear 810 meshing and transmission-connected with the driving gear 88 is fixedly mounted on the roller shaft 89, and the transmission shaft 87 is fixedly mounted on the output end of the transmission motor 85, so that one transmission motor 85 synchronously drives several roller shafts 89 to rotate;

[0056] In addition, the conveying roller 811 is used to transmit and transport the planar target material, and the transmission and transport position of the planar target material needs to be guaranteed so that the planar target material is above the immersion water tank 5 and the weighing and measuring device 6 to ensure that the planar target material can be stably weighed and measured. Therefore, a limiting baffle 812 is fixedly provided on the conveying slide 82, and the transmission and transport of the planar target material is limited by the limiting baffle 812 to ensure the accuracy of the target material transport position.

[0057] The feeding device 3 is used to transport the planar target material in and out. After the planar target material enters the measuring frame 4, it needs to be translated and transported by the conveying roller structure 8. In the process of entering and exiting the measuring frame 4, the planar target material needs to be positioned to ensure the accuracy of the target material's entry and exit position. Therefore, a limit mechanism needs to be set to realize the positioning of the target material in and out.

[0058] In an alternative embodiment, see Fig.14 and Fig.15 As shown, an inlet double-sided limiting mechanism 7 is provided at the feeding port of the measuring frame 4 on one side of the measuring frame 4 close to the feeding device 3, and the inlet double-sided limiting mechanism 7 is used to limit the inlet and outlet of the planar target material on both sides. Specifically, the inlet double-sided limiting mechanism 7 includes a fixing seat 1 71 and a fixing seat 2 74 fixedly mounted on the measuring frame 4, and side adjustment cylinders 72 are fixedly mounted on opposite surfaces of the fixing seat 1 71 and the fixing seat 2 74, and the output end of the side adjustment cylinder 72 of the fixing seat 1 71 is fixedly connected to a limiting frame 1 73, and the output end of the side adjustment cylinder 72 of the fixing seat 2 74 is fixedly connected to a limiting frame 2 75, and a plurality of limiting support plates 76 are fixedly mounted on opposite surfaces of the limiting support plates 76, and a plurality of limiting pulleys 77 are rotatably mounted on the limiting support plates 76.

[0059] When feeding a planar target material, it is necessary to calibrate the height of the target material so as to adjust the height of the target material during the subsequent measurement process. Specifically, a height measuring mechanism 79 is fixedly arranged on one side of the fixed seat 74. The height measuring mechanism 79 includes a height lifting module 791 fixedly mounted on the fixed seat 74. The output end of the height lifting module 791 is fixedly connected to a height lifting slide 792. A height measuring support plate 793 is fixedly mounted on the height lifting slide 792. A height sensor 794 for measuring the height of the planar target material is fixedly mounted on the height measuring support plate 793.

[0060] Since the planar target material needs to be transported back to the storage rack 1 after density measurement, and the plate needs to be soaked during density measurement, the target material needs to be air-dried to prevent dripping of the soaking liquid. A plurality of air blowing nozzles 78 are installed on the limit frame 1 73 and the limit frame 2 75. The air blowing nozzles 78 are connected to an external air supply system to achieve air drying of the planar target material.

[0061] In an alternative embodiment, see Fig. 9 and Fig.10As shown, the lifting mechanism 9 includes a fixed seat plate 91 fixedly mounted on the rear support box 10, a lifting guide rail 92 and a lifting screw module 93 are fixedly mounted on the fixed seat plate 91, a lifting support 94 is slidably connected to the lifting guide rail 92, and the lifting support 94 is fixedly connected to the sliding output end of the lifting screw module 93. The lifting mechanism 9 is used to realize the lifting and lowering adjustment of the weighing and measuring device 6, which is convenient for lifting and lowering the planar target material and immersing it in the soaking water tank 5 and removing it, and conveniently and quickly measuring the density of the planar target material.

[0062] In an alternative embodiment, see Figure 11-13 As shown, the weighing and measuring device 6 includes a weighing platform 61 and a bottom supporting mechanism 64 fixedly mounted on a lifting support 94, the upper end of the weighing platform 61 is fixedly connected to a weighing hanger 62 for hanging a planar target, and the bottom supporting mechanism 64 is used to drive the planar target to move up and down.

[0063] In an optional embodiment, the weighing sling 62 includes a sling upper frame 621 fixedly mounted on the weighing platform 61, a plurality of sling upper support rods 622 are fixedly connected to the sling upper frame 621, a weighing connecting frame 623 is fixedly connected to the lower end of the sling upper support rod 622, a plurality of sling lower support rods 626 are fixedly connected to the weighing connecting frame 623, two groups of sling lower plates 627 are fixedly connected to the lower ends of the sling lower support rods 626, and a plurality of U-shaped hangers 628 are fixedly connected between the two groups of sling lower plates 627.

[0064] Since the specifications of the flat targets are different, it is necessary to adjust the distance between the two sets of sling lower plates 627 to ensure stable weighing of targets of different specifications. Therefore, a sling adjustment rod 624 is fixedly connected to the lower end of the weighing connecting frame 623, and an adjustment support rod 625 is installed on the sling adjustment rod 624, and the sling lower support rod 626 is connected to the adjustment support rod 625 to adjust the position of the sling lower plates 627 on both sides to ensure that the weighing of targets of different specifications can be adapted.

[0065] In an optional embodiment, the bottom supporting mechanism 64 includes a supporting cylinder 641 and a supporting slide 643 fixedly mounted on a lifting support 94, a supporting slide 644 being slidably connected to the supporting slide 643, an output end of the supporting cylinder 641 being fixedly connected to the supporting slide 644 via a cylinder connecting plate 642, a supporting bottom plate 645 being fixedly mounted at the lower end of the supporting slide 644, and a plurality of supporting plates 646 being fixedly arranged on the supporting bottom plate 645.

[0066] Specifically, the cylinder connecting plate 642 is driven to move up and down by the extension and retraction of the support cylinder 641, and the support slide 643 plays a guiding and limiting role in the lifting and lowering movement of the support slide 644, ensuring that the lifting and lowering movement of the support slide 644 remains stable. When the target material needs to be measured, the support slide 644 moves downward, so that the target material falls completely onto the U-shaped hanger 628 for weighing. After the target material is weighed, the support slide 644 moves upward to lift the target material.

[0067] In an optional embodiment, since the target material needs to be removed from the conveying roller structure 8 and fed onto the conveying roller structure 8, a clamping mechanism needs to be provided on the bottom supporting mechanism 64 to clamp the target material and lift and transport it. Specifically, a side clamping mechanism 63 is installed on the bottom supporting mechanism 64 to clamp the upper part of the target material.

[0068] Specifically, the side clamping mechanism 63 includes a side clamping guide rail 631 and a side clamping motor seat 632 fixedly mounted on a supporting slide 644, wherein a side clamping slider 635 is slidably connected to the side clamping guide rail 631, and a side clamping assembly 636 for clamping the target material is fixedly mounted on the side clamping slider 635; two groups of sprocket assemblies 634 are installed on the supporting slide 644, and a driving chain 633 is transmission-connected between the two groups of sprocket assemblies 634, wherein the motor output end of the side clamping motor seat 632 is drivingly connected to the upper sprocket assembly 634, and the driving chain 633 is fixedly connected to the side clamping assembly 636, so as to realize the lifting and lowering drive of the side clamping assembly 636.

[0069] See also Fig.13 As shown, the side clamp assembly 636 is used to clamp the upper part of the target material. After the target material is clamped, the rotation of the drive chain 633 drives the side clamp assembly 636 to move up and down to adjust the height of the target material. Specifically, the side clamp assembly 636 includes a side clamp seat plate 6361 fixedly connected to the side clamp slider 635, and a plurality of groups of cylinder connecting plates 6362 and guide connecting plates 6363 are fixedly connected to the side clamp seat plate 6361. Side clamp cylinders 6362 are fixedly connected to both sides of the cylinder connecting plate 6362. 364, and the two groups of side clamping cylinders 6364 are oriented in opposite directions, the output ends of the two groups of side clamping cylinders 6364 are fixedly connected with clamping side plates 6366, and the guide connecting plate 6363 is fixedly connected with a clamping plate guide rod 6365, the two groups of clamping side plates 6366 are slidably connected to the clamping plate guide rod 6365, the clamping plate guide rod 6365 is used to guide the sliding of the clamping side plates 6366, and a plurality of side clamping wheels 6368 for clamping the target material are rotatably installed at the lower part of the clamping side plates 6366.

[0070] Since the flat target material needs to be transported back to the storage rack 1 after the density measurement, and the plate needs to be soaked during the density measurement, the target material needs to be air-dried to prevent the dripping of the soaking liquid. A plurality of air-drying air nozzles 6367 are installed on the clamping side plate 6366. The air-drying air nozzles 6367 are connected to the external air supply system to achieve air drying of the flat target material and blow away the water droplets on the target material and the suspension rod.

[0071] In an optional embodiment, a measurement method of a planar target density measurement system is specifically as follows: a planar target to be measured is placed in a storage rack 1, and then the storage rack 1 is sent to a feeding device 3 through a loading seat 2, and the planar target stored in the storage rack 1 is sent to a measuring rack 4 through the feeding device 3. When the target is sent to the measuring rack 4, the horizontal module 11 drives the laser rangefinder 15 to slide horizontally, and the vertical module 13 drives the laser rangefinder 15 to rise and fall, so as to use the laser rangefinder 15 to measure the planar target density. The size of the surface target is measured. After the size of the plane target is determined, the weighing and measuring device 6 first measures the dry weight of the plane target, and then completely immerses the plane target into the liquid in the immersion water tank 5. The weighing and measuring device 6 measures the wet weight of the plane target, and calculates the density of the plane target according to the dry weight, wet weight and size of the target. After the wet weight measurement of the target is completed, the plane target is returned to the storage rack 1, and the feeding device 3 adjusts the position of the storage rack 1 so that the density measurement of other plane targets is repeated.

[0072] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
