The zinc-tin alloy target material can be used to prepare various electronic components such as transparent conductive films, solar cells and display devices, and is widely used in the fields of semiconductors, optoelectronics and information technology. Since the zinc-tin alloy target material has good chemical properties, it is recycled after being used once. The impurities in the zinc-tin alloy target material will affect the performance of the material during recycling. Therefore, the zinc-tin alloy target material needs to be detected for impurities before being recycled.

[0003] The metal zinc-tin target material needs to be pretreated before impurity detection.

[0033] The surface of the moving rod 15 is fixedly connected with a gear four 27, the surface of the disc 28 is fixedly connected with a gear rack one 34 meshing with the gear four 27, the surface of the processing box 1 is fixedly installed with a circular shell 29, and one end of the rotating shaft two 30 extending into the circular shell 29 is provided with a coil spring 32.

[0034] More specifically, in the embodiment, As shown in Figure 1 and Figure 2 , the metal zinc tin target material to be recycled is poured into the processing box 1 through the downcomer 2, and the metal zinc tin target material will enter the crushing box 13 in the processing box 1 along the downcomer 2; As shown in Figure 4 , the motor one 26 is started, and under the meshing action of the gear one 54 and the gear two 55, the rotating rod one 24 and the rotating rod two 56 are driven to rotate, so that the two crushing rollers 25 rotate, and under the action of the crushing rollers 25, the metal zinc tin target material entering the crushing box 13 can be crushed before impurity detection; As shown in Figure 2 , Figure 5 , Figure 6 and Figure 10 , the motor three 40 is started at the same time, the rotating shaft one 36 and the gear three 35 are driven to rotate, under the meshing action of the gear three 35 and the gear teeth 33 on the surface of the disc 28, with the rotation of the gear three 35, the disc 28 and the rotating shaft two 30 will be driven to rotate, at the same time, the coil spring 32 in the circular shell 29 will start to store energy, when the gear three 35 is meshed with the gear teeth 33, under the action of the elastic potential energy of the coil spring 32, the rotating shaft two 30 and the disc 28 will be driven to rotate reversely and reset, that is, after the motor three 40 is started, the disc 28 will reciprocate, since the moving rod 15 is limited by the limiting groove 11 and can only move horizontally, with the reciprocating rotation of the disc 28, the position of the arc-shaped notches 31 will change, and the moving rod 15 will be pushed to move horizontally along the limiting groove 11, so that the two push plates 12 can move towards each other; It is worth noting that, as shown in Figure 5As shown, while the two moving rods 15 drive the two push plates 12 to move in the direction of approaching each other, the gear four 27 on the surface of the moving rod 15 will also mesh with the gear rack row one 34, so that the two push plates 12 are deflected downward while moving towards each other, thereby pushing the zinc-tin target material accumulated on both sides above the crushing roller 25 to the upper part of the crushing roller 25 for crushing, avoiding the problem that part of the zinc-tin target material is accumulated on the left and right sides above the crushing roller, causing blockage, improving the crushing efficiency of the zinc-tin target material, thereby improving the efficiency of the subsequent impurity detection of the zinc-tin target material.

[0035] In summary, after the motor three 40 is turned on, the meshing effect of the gear three 35 and the teeth 33 on the surface of the disc 28 and the energy storage of the coil spring 32 are utilized to realize the reciprocating rotation of the disc 28, so that the two push plates 12 are deflected downward while moving horizontally towards each other, which can accurately and dynamically clean the zinc-tin target material accumulated on both sides above the crushing roller 25. By pushing towards each other, the zinc-tin target material accumulated on both sides can be concentrated to the crushing area of the crushing roller 25, avoiding the blockage problem caused by local accumulation. By deflecting the push plate 12 downward, the zinc-tin target material can be effectively pressed into the crushing gap of the two crushing rollers 25, improving the crushing efficiency and greatly shortening the pretreatment time before the impurity detection of the zinc-tin target material, thereby improving the efficiency of the subsequent impurity detection of the zinc-tin target material.

[0036] The crushed zinc-tin target material will fall onto the screen 22 for screening. Since the screen 22 is inclined, the zinc-tin target material that meets the subsequent acid dissolution size after crushing will fall through the screen 22 into the dissolution cylinder 18 below for subsequent acid dissolution treatment, and the zinc-tin target material that is not completely crushed and has a larger size will move along the screen 22 into the collection box 4 for subsequent secondary crushing.

[0037] The pump body 9 is turned on, the acid solvent in the liquid storage cylinder 7 is input into the dissolution cylinder 18 through the liquid inlet pipe 10, and the subsequent acid dissolution operation can be performed. The liquid outlet pipe 3 is connected in communication with the feed inlet of the spectrometer. After the acid dissolution of the zinc-tin target material in the dissolution cylinder 18 is completed, the sample solution after acid dissolution can be input into the spectrometer for subsequent impurity detection. The impurity detection of metal by the spectrometer is a relatively mature existing technology, which will not be described here.

[0038] In Example Two, based on the above-mentioned embodiments: Further, the moving part in Example One is disclosed. The moving part includes a moving column 52 fixedly connected to the surface of the gear three 35, a moving frame 53 slidingly connected to the surface of the moving column 52, a connecting plate 51 fixedly connected to the surface of the moving frame 53, and the end of the connecting plate 51 is fixedly connected with the screen frame 17. The spring one 16 is arranged between the screen frame 17 and the inner wall of the treatment box 1. The surface of the processing box 1 is fixedly installed with a collecting box 4, the inner wall of the collecting box 4 is fixedly installed with an inclined plate 21, and the surface of the collecting box 4 is provided with a door body 6.

[0039] The lower surface of the processing box 1 is fixedly installed with a motor two 20, the output shaft of the motor two 20 is fixedly connected with a rotating shaft two 19, and the surface of the rotating shaft two 19 is fixedly connected with a plurality of arc-shaped protrusions 39 arranged in a circumferential array; Further comprising a sleeve 37, the surface of the sleeve 37 is provided with a slot into which the rotating shaft two 19 and the plurality of arc-shaped protrusions 39 are inserted and adapted, the surface of the sleeve 37 is fixedly connected with a plurality of stirring rods 38, the end portion of the sleeve 37 is rotationally connected with an arc-shaped block 41, the upper surface of the arc-shaped block 41 is arc-shaped, the surface of the arc-shaped block 41 is fixedly connected with a connecting rod one 42, the end portion of the connecting rod one 42 is fixedly connected with a rack two 46, the surface of the dissolving cylinder 18 is fixedly installed with a fixed block 49, the surface of the fixed block 49 is fixedly connected with a limiting rod two 47, the limiting rod two 47 extends into the rack two 46 and is slidably connected therewith, and the fixed block 49 and the rack two 46 are jointly provided with a spring two 48.

[0040] The inner wall of the processing box 1 is rotationally connected with a rotating shaft three 45, the surface of the rotating shaft three 45 is fixedly connected with a gear five 43 engaged with the rack two 46, the surface of the connecting plate 51 is fixedly connected with a connecting rod two 50, and the end portion of the connecting rod two 50 is fixedly connected with a rack three 44 engaged with the gear five 43.

[0041] More specifically, in the present embodiment: As shown in Figure 8 and Figure 9 When the motor three 40 is turned on, the rotation of the gear three 35 will drive the moving column 52 to move in a circular motion, and since the moving frame 53 slidably connected to the outer surface of the moving column 52 is fixedly connected to the screen frame 17 through the connecting plate 51, the circular motion of the moving column 52 will drive the moving frame 53, the connecting plate 51, the screen frame 17 and the screen 22 inside to move back and forth along the limiting rod one 23, compared with the stationary screen 22, it can avoid the crushed metal zinc tin target material from falling onto the fixed area of the screen 22 and causing accumulation, so that the metal zinc tin target material can be evenly distributed on the surface of the screen 22 when falling onto the screen 22 for screening, improving the screening quality and efficiency.

[0042] As shown in Figure 3 When the metal zinc tin target material in the dissolving cylinder 18 is acid-dissolved, the motor two 20 is turned on to drive the rotating shaft two 19 to rotate, and since the surface of the sleeve 37 is provided with a slot into which the rotating shaft two 19 and the plurality of arc-shaped protrusions 39 are inserted and adapted, the rotation of the rotating shaft two 19 will drive the sleeve 37 and the plurality of stirring rods 38 to rotate synchronously; It is worth noting that,Figure 7 and Figure 8 As shown, after the motor three 40 is turned on, with the reciprocating movement of the moving frame 53, under the connecting action of the connecting rod two 50, the rack row three 44 will be driven to reciprocate synchronously, and the gear five 43 will be driven to rotate reciprocally. Under the meshing action of the gear five 43 and the rack row two 46, the rack row two 46 will drive the arc block 41 to reciprocate in the vertical direction, so that the sleeve 37 can drive the multiple stirring rods 38 to reciprocate in the vertical direction while rotating, so as to better disturb the acid solvent in the dissolution cylinder 18 to acid-dissolve the metal zinc-tin target, and at the same time, it can avoid the accumulation of part of the metal zinc-tin target at the bottom of the dissolution cylinder 18, thereby improving the acid dissolution efficiency, thereby improving the subsequent impurity detection efficiency of the metal zinc-tin target.

[0043] In summary, through the highly integrated mechanical structure linkage design, the crushing and acid dissolution processes in the pretreatment process of the metal zinc-tin target before impurity detection are carried out simultaneously, and the single drive source motor 340 is used to achieve multi-link collaborative optimization, which significantly improves the pretreatment efficiency and quality. Specifically: When motor three 40 drives gear three 35 to rotate, it synchronously drives the push plate 12 to move toward each other and deflect downward, solving the problem of material accumulation above the crushing roller. At the same time, the screen 22 is reciprocated through the linkage of the moving column 52 and the moving frame 53, ensuring that the crushed material is evenly distributed and quickly screened; the qualified material after screening directly enters the dissolution cylinder 18. At this time, motor three 40 drives the stirring rod 38 through rack row three 44, gear five 43 and rack row two 46, so that the stirring rod 38 is superimposed with vertical reciprocating motion on the basis of the rotation driven by motor two 20, forming a three-dimensional stirring effect, greatly improving the acid dissolution efficiency, and integrating the original pretreatment process before the detection of discrete metal zinc and tin targets into a continuous operation, avoiding material transfer loss and waiting time. At the same time, the complexity of the transmission system is simplified through mechanical linkage, reducing energy consumption and failure points. More importantly, the efficient coordination of each link (uniform crushing to provide homogeneous raw materials for screening, thorough screening to provide materials with controllable particle size for acid dissolution, and sufficient acid dissolution to ensure the purity of the sample solution) has improved the accuracy of impurity detection in metal zinc-tin targets from the source, and is worthy of promotion and use.
