[0002] Indium is a rare metal widely used in solar photovoltaics, flat panel LCD displays, national defense, nuclear industry, aerospace, modern electronic information industry, and photovoltaic communication industry. These fields have high requirements for the purity of indium. With the development of these fields, the demand for high-purity indium is increasing. Currently, the production method of high-purity indium beads is generally to drip molten indium into a cooling liquid through a funnel for cooling and then take it out. This method is prone to producing high-purity indium beads of uneven size. At the same time, the high-purity indium beads are prone to the adhesion of cooling liquid to the surface, which requires cleaning after removal, which is time-consuming and labor-intensive.

[0012] As a further technical solution, the movable seat described above is equipped with a sealing mechanism that opens when indium liquid is introduced and closes when indium liquid is cooled. The sealing mechanism includes a fourth motor fixed to the machine body and located inside the upper cavity, a torsion spring sleeved on the outside of the movable seat, and a rotating seat sleeved on the outside of the torsion spring. The bottom end of the fourth motor extends through the machine body and into the lower cavity, where a tenth gear is fixedly sleeved. The two ends of the torsion spring are fixedly connected to the outer wall of the movable seat and the inner wall of the rotating seat, respectively. The top end of the rotating seat is fixedly sleeved with a fourth toothed ring that meshes with the tenth gear. The bottom end of the rotating seat is provided with a second communication port directly below the funnel.

[0013] A production method for a high-purity indium bead production apparatus includes the following steps: S1: Place a sufficient amount of indium ingot into the indium ingot melting box through the indium ingot inlet pipe. The electric heating coil is started by the programmable controller. The electric heating coil heats and melts the indium ingot, turning it into liquid indium, which is then discharged through the liquid indium outlet. S2: The third motor is started by controlling the programmable controller. The third motor drives the output shaft to rotate, which in turn drives the second conical wheel to rotate. The second conical wheel drives the first conical wheel to rotate. The first conical wheel drives the second connecting rod to rotate. The second connecting rod drives the first gear, the second gear, and the third gear to rotate. The first gear, the second gear, and the third gear drive the third gear ring, the second gear ring, and the first gear ring to rotate at the same speed. The third gear ring, the second gear ring, and the first gear ring drive the rotating liquid inlet plate, the upper mold, and the lower mold to rotate at the same speed. During the rotation of the rotating liquid inlet plate, the upper mold, and the lower mold at the same speed, the indium liquid outlet, multiple first connecting ports, the funnel, and multiple indium liquid inlets continuously overlap, pouring the indium liquid into the high-purity indium bead mold cavities formed by multiple high-purity indium bead half-cavities at the same position, until the multiple high-purity indium bead mold cavities are filled. The third motor is then stopped by controlling the programmable controller. S3: The fifth motor is started by controlling the programmable controller. The output shaft of the fifth motor rotates in the forward direction, which drives the first screw to rotate in the forward direction. During the forward rotation of the first screw, the movable seat moves downward on the first screw until the driving time of the fifth motor is over. The programmable controller controls the fifth motor to stop driving. At this time, the upper mold and the lower mold are completely immersed in the coolant for cooling until the cooling time is over. The programmable controller controls the fifth motor to drive in the reverse direction to reset the upper mold and the lower mold. S4: The programmable controller controls the first motor to start. The first motor drives the output shaft to rotate in the forward direction, which in turn drives the fourth gear to rotate in the forward direction. The fourth gear drives the meshing sixth gear to rotate in the reverse direction. The meshing sixth gear drives the drive shaft to rotate in the reverse direction. The drive shaft drives the two fifth gears to rotate in the reverse direction. During the reverse rotation of the two fifth gears, the two racks move downward. The lower mold moves downward synchronously under the action of gravity until the first motor drive time is up. The programmable controller controls the first motor to stop driving. At this time, the lower mold moves downward to the distance between it and the upper mold, which is convenient for adsorbing and picking up materials. S5: The drive shaft drives the sixth gear to rotate in the reverse direction, the sixth gear drives the ninth gear to rotate in the forward direction, the ninth gear drives the second screw to rotate in the forward direction. During the forward rotation of the second screw, the movable block moves on the second screw towards the ninth gear. The movable block drives the high-purity indium bead suction tube to move in the same direction until the first motor drive time is up and stops. At this time, the high-purity indium bead suction tube moves between the upper mold and the lower mold. The programmable controller controls the start of the exhaust fan. The exhaust fan suction creates a negative pressure state inside the high-purity indium bead suction tube. The high-purity indium beads in the high-purity indium bead mold cavity are suctioned into the high-purity indium bead suction tube and discharged through the high-purity indium bead outlet tube. At the same time, the programmable controller controls the start of the second motor. The second motor drives the output shaft to rotate, which drives the fourth conical wheel to rotate. The fourth conical wheel drives the third conical wheel to rotate. The third conical wheel drives the third connecting rod to rotate. The third connecting rod drives the seventh gear to rotate. The seventh gear drives the eighth gear to rotate. The eighth gear drives the first gear ring to rotate. The first gear ring drives the lower mold to rotate, realizing the suction and picking of multiple high-purity indium beads.

[0014] As a further technical solution, when the movable seat descends as described above, the fourth toothed ring on the rotating seat disengages from the restriction of the tenth gear, and the torsion spring resets, causing the rotating seat to reset. At this time, the second connecting port is offset from the indium liquid inlet, thereby sealing the indium liquid inlet, preventing the coolant from contacting the high-purity indium beads, and improving the purity of the high-purity indium beads when they are discharged.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention introduces molten indium liquid into different high-purity indium bead mold cavities in sequence, cools them, and then removes them in sequence by negative pressure adsorption. Compared with the prior art, the present invention can improve the quality uniformity of the produced high-purity indium beads, and at the same time avoid the situation where the high-purity indium beads come into contact with the coolant during the production process and need to be cleaned when they are removed, thus improving the convenience of subsequent material removal of high-purity indium beads.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0018] Please see Figure 1-10The present invention provides the following technical solution: a high-purity indium bead production apparatus, comprising: a body 1, wherein an upper cavity 2 and a lower cavity 12 containing coolant are respectively opened above and below the body 1; an indium ingot melting mechanism and an indium liquid inlet mechanism are respectively assembled from top to bottom inside the upper cavity 2; the indium liquid inlet mechanism extends into the lower cavity 12 and is equipped with a lifting mechanism that drives the indium liquid inlet mechanism to be immersed in coolant between the body 1 and the lifting mechanism; a support mechanism is assembled between the lifting mechanism and the indium liquid inlet mechanism; and a support mechanism is assembled on the side of the body 1 located inside the lower cavity 12 between the body 1 and the indium liquid inlet mechanism. The machine body 1 has a rotation drive mechanism. A high-purity indium bead feeding mechanism is installed on the other side of the lower cavity 12 inside the machine body 1 between the indium liquid feeding mechanism and the indium liquid feeding mechanism. A coolant inlet pipe 9 with a valve is fixedly connected to the side wall of the machine body 1 above the coolant level of the lower cavity 12. A coolant outlet pipe 10 with a valve is fixedly connected to the side wall of the machine body 1 at the bottom of the coolant level of the lower cavity 12. A programmable controller 11 is fixedly connected to the outer wall of the machine body 1. The indium ingot melting mechanism, indium liquid feeding mechanism, lifting mechanism, support mechanism, rotation drive mechanism and high-purity indium bead feeding mechanism are connected to the programmable controller 11 by wires.

[0019] See appendix Figure 1 Appendix Figure 9 and attached Figure 10 When the device produces high-purity indium beads, the indium ingot is melted by the indium ingot melting mechanism, and the molten indium is introduced into the high-purity indium bead mold cavity by the indium liquid inlet mechanism. The indium liquid inlet mechanism is immersed in the cooling liquid by the lifting mechanism for cooling. The indium liquid inlet mechanism is lifted and lowered by the support mechanism to open the indium liquid inlet mechanism, and the high-purity indium bead picking mechanism picks up the material. The indium liquid inlet mechanism is rotated by the rotation drive mechanism to realize the sequential picking of materials.

[0020] Specifically, the indium ingot melting mechanism includes an indium ingot melting box 3 fixed to the body 1 and located inside the upper cavity 2. An indium ingot inlet pipe 20 extending out of the upper cavity 2 is fixed to the top of the indium ingot melting box 3. An electric heating coil 21 is fixed to the outer wall of the indium ingot melting box 3. An indium liquid outlet 22 is opened at the bottom of the indium ingot melting box 3. The electric heating coil 21 is connected to the programmable controller 11 by wires.

[0021] Referring to Figure 2, the principle of the indium ingot melting mechanism is to place a sufficient amount of indium ingot into the indium ingot melting box 3 through the indium ingot inlet pipe 20, and to start the electric heating coil 21 by the programmable controller 11. The electric heating coil 21 heats and melts the indium ingot, turning it into liquid indium, which is then discharged through the liquid indium outlet 22.

[0022] Specifically, the indium liquid inlet mechanism includes a first connecting rod 19 fixed to the bottom of the indium ingot melting box 3, a funnel 5 fixed to the machine body 1 and located directly below the indium liquid outlet 22, an upper mold 30 and a lower mold 32 placed sequentially from top to bottom inside the lower cavity 12, a third motor 16 fixed to the outer wall of the machine body 1, and a second connecting rod 27 rotatably connected to the machine body 1 via bearings and extending to the upper cavity 2 and the lower cavity 12 respectively at both ends. A rotating inlet plate 4 is rotatably connected to the outside of the first connecting rod 19 via bearings. Multiple first connecting ports 23 are evenly spaced along the circumference on the rotating inlet plate 4 corresponding to the position of the indium liquid outlet 22. A third toothed ring 37 is fixed to the outer wall of the rotating inlet plate 4. The funnel 5 is located directly below the first connecting ports 23. The upper mold 30 is rotatably connected to the lifting mechanism via bearings. The lower mold 32 is sleeved on the lifting mechanism and movably connected to the lifting mechanism via a support mechanism. The top of the upper mold 30 corresponds to the position of the funnel 5. An indium liquid inlet 36, the same number as the first connecting port 23, is provided at equal intervals along the circumference. Two high-purity indium bead semi-cavities 33, which can form indium beads, are respectively provided below each indium liquid inlet 36 at the bottom of the upper mold 30 and the top of the lower mold 32. A second toothed ring 35 is fixedly connected to the outer wall of the upper mold 30, and a first toothed ring 34 is fixedly connected to the outer wall of the lower mold 32. The output shaft of the third motor 16 extends through the body 1 into the upper cavity 2 and is fixedly sleeved with a second conical wheel 26. From top to bottom, the second connecting rod 27 is sequentially fixedly sleeved with a first gear 24 that meshes with the third toothed ring 37 in the upper cavity 2, a first conical wheel 25 that meshes with the second conical wheel 26 in the upper cavity 2, a second gear 28 that meshes with the second toothed ring 35 in the lower cavity 12, and a third gear 29 that meshes with the first toothed ring 34 in the lower cavity 12. The third motor 16 is connected to the programmable controller 11 by wires.

[0023] See appendix Figure 3 The indium liquid inlet mechanism works by using a programmable controller 11 to control the start of a third motor 16. The third motor 16 drives the output shaft to rotate, which in turn rotates the second conical wheel 26. The second conical wheel 26 then rotates the first conical wheel 25. The first conical wheel 25 rotates the second connecting rod 27. The second connecting rod 27 then rotates the first gear 24, the second gear 28, and the third gear 29. The first gear 24, the second gear 28, and the third gear 29 then rotate the third gear ring 37, the second gear ring 35, and the first gear ring 34 at the same speed. The three-toothed ring 37, the second toothed ring 35, and the first toothed ring 34 drive the rotating liquid inlet plate 4, the upper mold 30, and the lower mold 32 to rotate at the same speed. During the rotation of the rotating liquid inlet plate 4, the upper mold 30, and the lower mold 32 at the same speed, the indium liquid outlet 22, multiple first connecting ports 23, the funnel 5, and multiple indium liquid inlets 36 continuously overlap, pouring the indium liquid into the high-purity indium bead mold cavities formed by multiple high-purity indium bead half-cavities 33 at the same position, until the multiple high-purity indium bead mold cavities are filled. Then, the third motor 16 is stopped by the programmable controller 11.

[0024] Specifically, the lifting mechanism includes a fifth motor 18 fixed to the body 1 and located inside the upper cavity 2. The output shaft of the fifth motor 18 extends through the body 1 into the lower cavity 12 and is fixed to a first screw 38 via a coupling. The bottom end of the first screw 38 is connected to the bottom end of the body 1 via a bearing. A movable seat 31 is connected to the outside of the first screw 38 via a transmission nut. The upper mold 30 is rotatably connected to the movable seat 31 via a bearing. The lower mold 32 is sleeved on the movable seat 31 and is movably connected to the movable seat 31 via a support mechanism. The fifth motor 18 is connected to the programmable controller 11 via wires.

[0025] See appendix Figure 4 The lifting mechanism works by controlling the fifth motor 18 to start via the programmable controller 11. The fifth motor 18 drives the output shaft to rotate in the forward direction, which in turn drives the first screw 38 to rotate in the forward direction. During the forward rotation of the first screw 38, the movable seat 31 moves downward on the first screw 38 until the driving time of the fifth motor 18 is up. At this time, the programmable controller 11 controls the fifth motor 18 to stop driving. The upper mold 30 and the lower mold 32 are completely immersed in the coolant for cooling until the cooling time is up. Then, the programmable controller 11 controls the fifth motor 18 to drive in the reverse direction to reset the upper mold 30 and the lower mold 32.

[0026] Specifically, the support mechanism includes two racks 49 symmetrically placed on both sides of the movable seat 31, two side limiting grooves 41 symmetrically opened on the lower part of the movable seat 31, two bottom limiting plates 45 symmetrically fixed to the bottom end of the movable seat 31, a drive shaft 47 rotatably connected to the movable seat 31 and perpendicular to the two racks 49 via bearing seats, and a first motor 13 fixed to the outer wall of the body 1. A rolling groove is opened at the top of the racks 49, and a roller 39 is fixedly connected inside the rolling groove. Ball bearings 50 are rotatably connected to the outside of the roller 39 via a perforated sleeve. Side limiting plates 40 are fixedly connected to the upper part of the side walls of the two racks 49 close to each other. The side limiting grooves 41 are fixed inside... A side limiting rod 44 is connected, and a side limiting plate 40 is movably connected to the side limiting rod 44 through an opening sleeve. Two limiting holes 46 are symmetrically opened on the bottom limiting plate 45. The bottom ends of two racks 49 pass through the limiting holes 46 on the same side respectively. A fifth gear 43 is fixedly sleeved on the drive shaft 47 corresponding to the positions of the two racks 49 and meshes with the racks 49 at the same positions. A sixth gear 48 is fixedly sleeved at both ends of the drive shaft 47. The output shaft of the first motor 13 extends through the body 1 to the lower cavity 12 and is fixedly sleeved with a fourth gear 42 that meshes with the sixth gear 48 on the same side. The first motor 13 is connected to the programmable controller 11 by wires.

[0027] See appendix Figure 5The support mechanism works by controlling the first motor 13 to start via the programmable controller 11. The first motor 13 drives the output shaft to rotate forward, which in turn drives the fourth gear 42 to rotate forward. The fourth gear 42 drives the meshing sixth gear 48 to rotate in the opposite direction. The meshing sixth gear 48 drives the drive shaft 47 to rotate in the opposite direction. The drive shaft 47 drives the two fifth gears 43 to rotate in the opposite direction. During the reverse rotation of the two fifth gears 43, the two racks 49 move downward. The lower mold 32 moves downward synchronously under the action of gravity until the driving time of the first motor 13 is up. The programmable controller 11 then controls the first motor 13 to stop driving. At this time, the lower mold 32 moves downward to the distance between itself and the upper mold 30, which is convenient for adsorbing and picking up materials.

[0028] Specifically, the rotation drive mechanism includes a second motor 15 fixed to the side wall of the body 1 and a fixed plate 14 fixed to the inner wall of the lower cavity 12. The output shaft of the second motor 15 extends through the body 1 into the lower cavity 12 and is fixedly sleeved with a fourth conical wheel 53. The fixed plate 14 is rotatably connected to a third connecting rod 54 near the second motor 15 and a fourth connecting rod 55 away from the second motor 15 through two bearings. The top end of the third connecting rod 54 is fixedly sleeved with a third conical wheel 52 that meshes with the fourth conical wheel 53. The bottom end of the third connecting rod 54 is fixedly sleeved with a seventh gear 51. The bottom end of the fourth connecting rod 55 is fixedly sleeved with an eighth gear 56 that meshes with the seventh gear 51 and the first gear ring 34. The second motor 15 is connected to the programmable controller 11 by wires.

[0029] See appendix Figure 6 The principle of the rotation drive mechanism is that the programmable controller 11 controls the second motor 15 to start, the second motor 15 drives the output shaft to rotate, which drives the fourth conical wheel 53 to rotate, the fourth conical wheel 53 drives the third conical wheel 52 to rotate, the third conical wheel 52 drives the third connecting rod 54 to rotate, the third connecting rod 54 drives the seventh gear 51 to rotate, the seventh gear 51 drives the eighth gear 56 to rotate, the eighth gear 56 drives the first gear ring 34 to rotate, and the first gear ring 34 drives the lower mold 32 to rotate, thereby realizing the adsorption and picking of multiple high-purity indium beads.

[0030] Specifically, the high-purity indium bead feeding mechanism includes a movable opening 7 on the body 1 and a second screw 58 located below the movable opening 7 and rotatably connected to the body 1 via a bearing. A high-purity indium bead suction pipe 8 is placed inside the movable opening 7. A fan with a filter screen is fixedly connected to the suction end of the high-purity indium bead suction pipe 8, and a high-purity indium bead outlet pipe 57 is fixedly connected to the discharge end of the high-purity indium bead suction pipe 8. A movable block 59, located outside the body 1, is connected to the bottom end of the high-purity indium bead suction pipe 8 via a transmission nut on the second screw 58. A ninth gear 60, which meshes with the sixth gear 48 on the side away from the first motor 13, is fixedly sleeved at the end of the second screw 58 away from the movable block 59. The fan is connected to the programmable controller 11 via a wire.

[0031] See appendix Figure 7 The principle of the high-purity indium bead feeding mechanism is as follows: the drive shaft 47 drives the sixth gear 48 to rotate in the opposite direction, the sixth gear 48 drives the ninth gear 60 to rotate in the forward direction, the ninth gear 60 drives the second screw 58 to rotate in the forward direction, and during the forward rotation of the second screw 58, the movable block 59 moves on the second screw 58 towards the direction of the ninth gear 60. The movable block 59 drives the high-purity indium bead suction tube 8 to move in the same direction until the first motor 13 stops driving. At this time, the high-purity indium bead suction tube 8 moves between the upper mold 30 and the lower mold 32. The programmable controller 11 controls the start of the exhaust fan. The exhaust fan suction creates a negative pressure state inside the high-purity indium bead suction tube 8, and the high-purity indium beads in the high-purity indium bead mold cavity are sucked into the high-purity indium bead suction tube 8 and discharged through the high-purity indium bead outlet tube 57.

[0032] A production method for a high-purity indium bead production apparatus includes the following steps: S1: Place a sufficient amount of indium ingot into the indium ingot melting box 3 through the indium ingot inlet pipe 20. The electric heating coil 21 is started by the programmable controller 11. The electric heating coil 21 heats and melts the indium ingot, turning it into liquid indium, which is then discharged through the liquid indium outlet 22. S2: The programmable controller 11 controls the start of the third motor 16. The third motor 16 drives the output shaft to rotate, which in turn drives the second conical wheel 26 to rotate. The second conical wheel 26 drives the first conical wheel 25 to rotate. The first conical wheel 25 drives the second connecting rod 27 to rotate. The second connecting rod 27 drives the first gear 24, the second gear 28, and the third gear 29 to rotate. The first gear 24, the second gear 28, and the third gear 29 drive the third gear ring 37, the second gear ring 35, and the first gear ring 34 to rotate at the same speed. 37. The second toothed ring 35 and the first toothed ring 34 drive the rotating liquid inlet plate 4, the upper mold 30 and the lower mold 32 to rotate at the same speed. During the rotation of the rotating liquid inlet plate 4, the upper mold 30 and the lower mold 32 at the same speed, the indium liquid outlet 22, multiple first connecting ports 23, the funnel 5 and multiple indium liquid inlets 36 continuously overlap, pouring the indium liquid into the high-purity indium bead mold cavity formed by multiple high-purity indium bead half-cavities 33 at the same position, until the multiple high-purity indium bead mold cavities are filled. The third motor 16 is stopped by the programmable controller 11. S3: The programmable controller 11 controls the fifth motor 18 to start. The fifth motor 18 drives the output shaft to rotate in the forward direction, which in turn drives the first screw 38 to rotate in the forward direction. During the forward rotation of the first screw 38, the movable seat 31 moves downward on the first screw 38 until the driving time of the fifth motor 18 is over. The programmable controller 11 controls the fifth motor 18 to stop driving. At this time, the upper mold 30 and the lower mold 32 are completely immersed in the coolant for cooling until the cooling time is over. The programmable controller 11 controls the fifth motor 18 to drive in the reverse direction to reset the upper mold 30 and the lower mold 32. S4: The programmable controller 11 controls the first motor 13 to start. The first motor 13 drives the output shaft to rotate in the forward direction, which in turn drives the fourth gear 42 to rotate in the forward direction. The fourth gear 42 drives the meshing sixth gear 48 to rotate in the reverse direction. The meshing sixth gear 48 drives the drive shaft 47 to rotate in the reverse direction. The drive shaft 47 drives the two fifth gears 43 to rotate in the reverse direction. During the reverse rotation of the two fifth gears 43, the two racks 49 are driven to move downward. The lower mold 32 moves downward synchronously under the action of gravity until the driving time of the first motor 13 is up. The programmable controller 11 controls the first motor 13 to stop driving. At this time, the lower mold 32 moves downward to the distance between it and the upper mold 30, which can be used to easily pick up the material. S5: Drive shaft 47 drives sixth gear 48 to rotate in the reverse direction, sixth gear 48 drives ninth gear 60 to rotate in the forward direction, ninth gear 60 drives second screw 58 to rotate in the forward direction. During the forward rotation of second screw 58, movable block 59 moves on second screw 58 towards the direction of ninth gear 60. Movable block 59 drives high-purity indium bead suction tube 8 to move in the same direction until the first motor 13 stops driving after its designated time. At this time, high-purity indium bead suction tube 8 moves between upper mold 30 and lower mold 32. The programmable controller 11 controls the start of the exhaust fan, and the exhaust fan suction creates a negative pressure state inside high-purity indium bead suction tube 8. High-purity indium beads inside the high-purity indium bead mold cavity are adsorbed into the high-purity indium bead suction tube 8 and discharged through the high-purity indium bead outlet tube 57. At the same time, the programmable controller 11 controls the second motor 15 to start. The second motor 15 drives the output shaft to rotate, which in turn drives the fourth conical wheel 53 to rotate. The fourth conical wheel 53 drives the third conical wheel 52 to rotate. The third conical wheel 52 drives the third connecting rod 54 to rotate. The third connecting rod 54 drives the seventh gear 51 to rotate. The seventh gear 51 drives the eighth gear 56 to rotate. The eighth gear 56 drives the first gear ring 34 to rotate. The first gear ring 34 drives the lower mold 32 to rotate, thereby realizing the adsorption and extraction of multiple high-purity indium beads. Example 2:

[0033] The difference between this embodiment and Embodiment 1 is that: Specifically, the movable seat 31 is equipped with a sealing mechanism that opens when indium liquid is introduced and closes when indium liquid is cooled. The sealing mechanism includes a fourth motor 17 fixed to the body 1 and located inside the upper cavity 2, a torsion spring 62 sleeved on the outside of the movable seat 31, and a rotating seat 6 sleeved on the outside of the torsion spring 62. The bottom end of the fourth motor 17 extends through the body 1 and into the lower cavity 12, where a tenth gear 61 is fixedly sleeved. The two ends of the torsion spring 62 are fixedly connected to the outer wall of the movable seat 31 and the inner wall of the rotating seat 6, respectively. The top end of the rotating seat 6 is fixedly sleeved with a fourth toothed ring 63 that meshes with the tenth gear 61. The bottom end of the rotating seat 6 is provided with a second communication port 64 directly below the funnel 5.

[0034] A production method for a high-purity indium bead production apparatus further includes the following steps: When the movable seat 31 descends, the fourth toothed ring 63 on the rotating seat 6 disengages from the restriction of the tenth gear 61, and the torsion spring 62 resets, causing the rotating seat 6 to reset. At this time, the second connecting port 64 is offset from the indium liquid inlet 36, thereby closing the indium liquid inlet 36, preventing the coolant from contacting the high-purity indium beads, and improving the purity of the high-purity indium beads when they are discharged.
