Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an automatic packing device for indium ingots. Background Art

[0002] Indium metal is a silver-white metal with a slightly pale blue luster. Indium is very soft in texture, and scratches can be easily left on its surface with a fingernail. Indium has good plasticity and ductility and can be pressed into thin sheets. Therefore, indium is mainly used in the production of ITO targets (for liquid crystal displays and flat screens), semiconductor materials and devices, etc. When storing indium ingots, they should be separated from other metals. Non-metallic containers such as plastic or glass can be used for packaging, which can prevent the indium ingots from oxidation or other contamination.

[0003] Currently, most indium ingots on the market are packaged with plastic seal bags during packaging. However, plastic seal bags can only protect indium ingots from oxidation. Since the material of indium ingots is relatively soft, they are prone to deformation due to knocking, bumping, and impact during transportation, thus affecting their appearance. If glass bottles are used for packaging indium, the packaging cost will be increased. Summary of the Invention

[0004] The present invention overcomes the disadvantages in the prior art, and provides a forming component and a covering component. The forming component presses out a placement groove on the PVC hard sheet. The size of the placement groove is larger than that of the indium ingot. Due to the certain hardness of the placement groove, when the packaged indium ingot is impacted or squeezed, the placement groove can protect the indium ingot from deformation or being scratched. The covering component seals the opening of the placement groove, so that the indium ingot is in a sealed space, avoiding oxidation of the indium ingot or reaction with other metals, and ensuring the purity of the indium ingot.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not intended to limit the present invention.

[0021] As shown Figures 1 to 17 is an automatic packing device for indium ingots, which is used for hermetically packaging indium ingots. It includes a forming component 5 and a covering component 8. The forming component 5 includes a bottom die part 503 and an upper die part 505. When the PVC hard sheet passes through the forming component 5, the bottom die part 503 and the upper die part 505 are closed to press a placement groove on the PVC hard sheet. The manipulator places the silver ingot into the placement groove. The PVC hard sheet moves with the indium ingot to the covering component 8. The size of the placement groove is larger than that of the indium ingot. Since the placement groove has a certain hardness, when the packaged indium ingot is impacted or squeezed, the placement groove can protect the indium ingot from deformation or being scratched. The covering component 8 is provided with a covering PVC reel 802, and the PVC soft sheet roll is arranged at the covering PVC reel 802. The covering component 8 is also provided with a covering hot pressing part 806. A pressure-bearing part 808 is arranged directly below the covering hot pressing part 806. After the PVC soft sheet and the PVC hard sheet with the indium ingot overlap, they pass through between the covering hot pressing part 806 and the pressure-bearing part 808. The covering hot pressing part 806 includes a hot pressing plate 8063, and the hot pressing plate 8063 is detachably connected with a hot pressing conversion plate 8064. After the hot pressing plate 8063 is energized, it generates heat and transfers the heat to the hot pressing conversion plate 8064. The hot pressing conversion plate 8064 presses down to press the PVC soft sheet and the PVC hard sheet with the indium ingot together. The covering component 8 seals the opening of the placement groove, so that the indium ingot is in a sealed space, avoiding the indium ingot from being oxidized or reacting with other metals, and ensuring the purity of the indium ingot.

[0022] The bottom die component 503 includes a bottom die base block 5031 and a bottom die conversion block 5032; a bottom die slide rail 503E is provided on the bottom die base block 5031, a limiting strip 503D is provided on one side of the bottom die slide rail 503E, and a first side lock chute 503F is further provided at one end of the bottom die base block 5031 away from the limiting strip 503D; a chute 503B is provided at the lower end of the bottom die conversion block 5032, a limiting groove 503A is provided at one end of the chute 503B, and a second side lock chute 503C is provided at one end of the bottom die conversion block 5032 away from the limiting groove 503A; the chute 503B is slidably connected to the bottom die slide rail 503E; when the bottom die base block 5031 coincides with the bottom die conversion block 5032, the limiting groove 503A is engaged with the limiting strip 503D, so that the limiting groove 503A can prevent misalignment when the bottom die base block 5031 is docked with the bottom die conversion block 5032, enabling quick positioning when the bottom die base block 5031 is combined with the bottom die conversion block 5032, and the first side lock chute 503F coincides with the second side lock chute 503C; both the first side lock chute 503F and the second side lock chute 503C are slidably connected to a side lock block 5033, and the side lock block 5033 is connected to the bottom die base block 5031 and the bottom die conversion block 5032 through side lock bolts 5034. When the size of the indium ingot to be packaged changes, that is, the size of the placement groove needs to change, at this time, it can be achieved by replacing different bottom die conversion blocks 5032. First, remove the side lock bolt 5034 connected to the bottom die conversion block 5032, loosen the side lock bolt 5034 connected to the bottom die base block 5031, and then move the side lock block 5033 towards the bottom die base block 5031. When the side lock block 5033 no longer blocks the side of the bottom die conversion block 5032, the bottom die conversion block 5032 can be slid out from the side away from the limiting strip 503D. Then, insert the chute 503B of the new bottom die conversion block 5032 into the bottom die slide rail 503E, and push the new bottom die conversion block 5032 into the bottom die base block 5031 until the limiting groove 503A is engaged with the limiting strip 503D. Then, push the side lock block 5033 towards the bottom die conversion block 5032 to block the side of the bottom die conversion block 5032, and then pass the side lock bolt 5034 through the side lock block 5033 to connect with the bottom die conversion block 5032, thus completing the process of replacing the bottom die conversion block 5032. The whole process is simple to operate and can be quickly positioned, so it is very convenient for the operator.

[0023] The forming assembly 5 further includes a forming base 501. A support column 5011 is provided on the forming base 501. A forming upper plate 504 and an adjusting gasket 507 are inserted on the support column 5011. The top end of the support column 5011 is connected to a top nut 508. When the thickness of the indium ingot changes, the depth of the placing groove changes. At this time, the thickness of the bottom die replacement block 5032 also changes. Therefore, when the bottom die replacement block 5032 is lifted by the forming lifting cylinder 502, its highest height will also change accordingly. At this time, by adjusting the positions of the forming upper plate 504 and the adjusting gasket 507, the height of the forming upper plate 504 can be set, so that the forming assembly 5 can adapt to the packaging of indium ingots of different sizes.

[0024] The forming base 501 is connected to the forming lifting cylinder 502. A bottom die lifting rail 503G is provided at the lower end of the bottom die base block 5031. The output end of the forming lifting cylinder 502 is connected to the bottom die base block 5031. The bottom die lifting rail 503G is movably inserted into the forming base 501. The forming lifting cylinder 502 pushes the bottom die component 503 upward, so that the bottom die component 503 is engaged with the upper die component 505, and thus the heated and softened PVC hard sheet can be pressed out to form the placing groove.

[0025] The upper die component 505 and the forming upper plate 504 are connected by die locking bolts 506; a upper plate slide rail 5041 is provided at the lower end of the forming upper plate 504. The upper die component 505 includes an upper die base block 5051, and an upper die chute 505A is provided on the upper die base block 5051. The upper plate slide rail 5041 is inserted into the upper die chute 505A; a punch positioning groove 505C is provided on the forming upper plate 504, and a punch insertion hole 505D is provided in the punch positioning groove 505C. The punch positioning groove 505C is detachably connected with a punch 5052. The punch 5052 includes a punch insertion post 505E, and the punch insertion post 505E is inserted into the punch insertion hole 505D; a die locking strip 5054 is inserted into the upper die base block 5051. The die locking strip 5054 penetrates into the upper die base block 5051 from one side, and the die locking strip 5054 is inserted together with the punch insertion post 505E, and finally the die locking strip 5054 penetrates out from the other side of the upper die base block 5051; one end of the die locking strip 5054 penetrating out of the upper die base block 5051 is connected with a die locking nut 5053. When replacing the punch 5052, it is necessary to first remove the upper die base block 5051. Just loosen the die locking bolts 506, and the upper die component 505 can be pulled out along the upper plate slide rail 5041. Then remove the die locking nut 5053 and pull out the die locking strip 5054, and the punch 5052 can be taken out from the upper die base block 5051. After replacing with a new punch 5052, insert the die locking strip 5054 into the upper die base block 5051 again, so that the die locking strip 5054 can insert the punch 5052 and the upper die base block 5051 together. In this way, when replacing the punch 5052, it is very fast and one upper die base block 5051 can adapt to a variety of different punches 5052, making the upper die component 505 more adaptable and more flexible in use.

[0026] The cover assembly 8 includes a cover base 801; a cover roll transition shaft 804 is provided on one side of the cover base 801. The cover hot pressing component 806 further includes a hot pressing cylinder 8061. The hot pressing plate 8063 is connected to the output end of the hot pressing cylinder 8061. The hot pressing plate 8063 is also connected with a first spring 8062, and the other end of the first spring 8062 is connected with the cover base 801; the first spring 8062 also plays a role of pulling and limiting the hot pressing plate 8063. When the hot pressing cylinder 8061 pulls up the hot pressing plate 8063, the first spring 8062 can play an auxiliary role.

[0027] The pressure-bearing component 808 includes a pressure-bearing base 8081. The pressure-bearing base 8081 is connected to a second spring 8082. The other end of the second spring 8082 is connected to a pressure-bearing bottom plate 8084. The lower end of the pressure-bearing bottom plate 8084 is connected to a pressure-bearing guide post 8083. The pressure-bearing guide post 8083 is movably inserted into the pressure-bearing base 8081. When the hot-pressing conversion plate 8064 hot-presses the PVC hard sheet and the PVC soft sheet with indium ingots, causing the contact areas between the two to fuse together, the second spring 8082 is compressed downward. At this time, the second spring 8082 can exert an upward thrust on the PVC hard sheet, making the PVC hard sheet and the PVC soft sheet fit more closely, resulting in a better bonding effect between the two.

[0028] On both sides of the pressure-bearing base 8081, there are hot-pressing side limiting components 807 connected. The hot-pressing side limiting component 807 includes a hot-pressing limiting block 8071. On one side of the hot-pressing limiting block 8071, there is a hot-pressing limiting slide rod 8072.

The hot-pressing limiting slide rod 8072 is slidably inserted into the pressure-bearing base 8081, and the hot-pressing limiting adjusting screw 8073 is threadedly connected to the pressure-bearing base 8081. By rotating the hot-pressing limiting adjusting screw 8073, the position between the two hot-pressing limiting blocks 8071 can be adjusted, so as to limit all the PVC hard sheets and PVC soft sheets with indium ingots in the middle, facilitating the alignment of the acting directions of the two, and making the final sealing effect better.

[0029] A power component 6 and an indium ingot loading platform 7 are arranged between the forming component 5 and the cover component 8. On the side of the forming component 5 away from the cover component 8, there are a film roll component 1, a transition shaft component 2, a tensioning component 3, and a preheating component 4 arranged from far to near. On the side of the cover component 8 away from the forming component 5, there are a power component 6 and a receiving conveyor belt 9 arranged from near to far. The roll-shaped PVC hard sheet is installed on the film roll component 1. After the PVC hard sheet is pulled out, it passes through the transition shaft component 2 and the tensioning component 3 and is sent into the preheating component 4. The preheating component 4 heats the PVC hard sheet to make it soft. The softened PVC hard sheet then passes through the forming component 5 to press out a placement groove. Driven by the power component 6, the PVC hard sheet with the placement groove passes through the indium ingot loading platform 7. A manipulator is arranged on the side of the indium ingot loading platform 7. The manipulator grabs the indium ingot from an external positioning platform and places it into the placement groove. The cover hot-pressing component 806 presses a layer of PVC soft sheet at the opening of the placement groove. The encapsulated indium ingot is pushed onto the receiving conveyor belt 9 driven by the second group of power components 6.

[0030] The indium ingot loading platform 7 includes a platform base 701. On both sides above the platform base 701, there are width adjustment blocks 702, and the width adjustment blocks 702 are connected to the platform base 701 through fixing bolts 703. When the PVC hard sheet for pressing out the placement groove comes to the indium ingot loading platform 7, the width adjustment blocks 702 can limit its left and right positions, making the positioning more accurate when the manipulator places the indium ingot into it.

[0031] The film roll assembly 1 includes a lever 102. The middle of the lever 102 is rotatably connected to a lever bracket 101. One end of the lever 102 is provided with a film roll placement groove 1021. A locking block 1022 is hinged to the side of the film roll placement groove 1021, and the locking block 1022 is connected to a locking bolt 1023; the end of the lever 102 away from the film roll placement groove 1021 is provided with a force application rod 1024; above the force application rod 1024, there is a lever lifting cylinder 103. On both sides of the lever lifting cylinder 103, there are lifting positioning rods 104, and the output end of the lever lifting cylinder 103 is connected to a push plate 105; since the rolled PVC hard sheet is relatively heavy, during installation, the lever lifting cylinder 103 can be retracted first. At this time, the end of the lever 102 provided with the film roll placement groove 1021 can be easily pressed down by the operator. Then, the rolled PVC hard sheet is pushed above the film roll placement groove 1021, and then the output end of the lever lifting cylinder 103 is pushed out. The push plate 105 presses the force application rod 1024 downward, and the film roll placement groove 1021 at the other end of the lever 102 rises; the rolled PVC hard sheet at the other end of the lever will be lifted, facilitating the subsequent pulling out of the PVC hard sheet during the use of the equipment. The setting of the film roll assembly 1 makes it more labor-saving for the operator to replace the rolled PVC hard sheet.

[0032] The tensioning assembly 3 includes a tensioning cylinder 301. The output end of the tensioning cylinder 301 is connected to a tensioning shaft 302. After the PVC hard sheet is pulled out and wound around the equipment, the tensioning cylinder 301 pushes out the tensioning shaft 302 to tension the PVC hard sheet, making the positioning of the PVC hard sheet more accurate during processing.

[0033] The preheating assembly 4 includes a preheating frame body 401. The preheating frame body 401 is connected to a first preheating belt 402. On both sides of the preheating frame body 401, there are preheating lifting frame bodies 403. The preheating lifting frame bodies 403 are connected to preheating lifting cylinders 404. The output end of the preheating lifting cylinder 404 is connected to a second preheating belt 405. Heating components are arranged in the first preheating belt 402 and the second preheating belt 405, such as an electric heating plate that generates heat when powered on. Therefore, the belt surfaces of the first preheating belt 402 and the second preheating belt 405 have a certain amount of heat. When the PVC hard sheet passes between the first preheating belt 402 and the second preheating belt 405, it is quickly softened, so that when it reaches the forming assembly 5, the PVC hard sheet can be pressurized and shaped. Moreover, after being shaped by the forming assembly 5, the temperature of the PVC hard sheet can also be quickly reduced. Therefore, when the shaped PVC hard sheet is transferred to the indium ingot, its temperature will not affect the stability of the silver ingot.

[0034] The power assembly 6 includes a power shaft 604. Both ends of the power shaft 604 are connected to power lifting seats 603. The power lifting seats 603 are slidably connected to a power base 601. The power base 601 is connected to a power lifting cylinder 602.
