Abstract
Description
Technical Field
[0001] The present application relates to the technical field of globe manufacturing technology, and in particular to a method for manufacturing a three-dimensional globe and related devices. Background Art
[0002] There are several ways to make a three-dimensional globe using printed sheets, such as the in-film pasting method and the coating method. For example, the in-film pasting method is to first place a three-dimensional hemispherical cap of a polyvinyl chloride (PVC) sheet in an injection mold, and then inject acrylonitrile-styrene-butadiene copolymer (ABS) plastic into the injection mold to tightly combine the ABS plastic with the three-dimensional hemispherical cap and achieve a three-dimensional support effect, thereby obtaining a well-fitted three-dimensional globe. However, the in-film pasting method is complicated in process, and many sliders must be made on the injection mold to facilitate the demoulding of the three-dimensional terrain. The yield rate of this method is low and the cost is also high. The coating method is to process the printed PVC sheet into a three-dimensional shape through a process such as vacuum forming, and then coat it on the bladder to form a three-dimensional globe. Compared with the in-film pasting method, this method is simpler in process and has lower cost, but the bonding effect is not as good as the in-film pasting method. Therefore, the existing three-dimensional globe is made by improving the coating method, that is, when the sheet is coated on the bladder, a negative mold heating mold is made to pressurize and fit during the coating. The negative mold heating mold can well assemble the sheet to the bladder, but the production cost of the negative mold heating mold is also relatively high.
[0003] Therefore, when making a three-dimensional globe with a topographic structure, how to make a high-quality three-dimensional globe at a low cost becomes a problem that needs to be solved urgently. Summary of the invention

[0029] In the embodiments of the present application, “millimeter (MM)” and “kilometer (KM)” are mentioned as length units.
[0030] There are several ways to make a printed sheet 3D globe, including the following: in-film pasting and coating. For example, in the in-film pasting method, a 3D hemispherical cap of a PVC sheet is first placed in an injection mold, and ABS plastic is injected into the injection mold to tightly combine the ABS plastic with the 3D hemispherical cap, and achieve a 3D support effect, thereby obtaining a well-fitted 3D globe. However, the in-film pasting method is complex in process, and many sliders must be made on the injection mold to facilitate the demoulding of the 3D terrain. The yield rate of this method is low and the cost is also high. The coating method is to process the printed PVC sheet into a three-dimensional shape through a process such as vacuum forming, and then coat it on the bladder to form a three-dimensional globe. Compared with the in-film pasting method, this method is simpler in process and has lower cost, but the bonding effect is not as good as the in-film pasting method. Therefore, the existing three-dimensional globe is made by improving the coating method, that is, when the sheet is coated on the bladder, a negative mold heating mold is made to pressurize and fit during the coating. The negative mold heating mold can well assemble the sheet to the bladder, but the production cost of the negative mold heating mold is also relatively high.
[0031] In order to solve the above problems, the embodiment of the present application provides a method for making a three-dimensional globe and a related device, wherein the method for making a three-dimensional globe is applied to a three-dimensional globe making device, wherein the three-dimensional globe making device includes a three-dimensional ball cap blister device and a ball cap bladder assembly device, and the ball cap bladder assembly device includes a vacuum negative pressure device and a high-pressure and high-temperature steam device, and the method includes: blistering a target printed sheet into a first hemispherical cap through a blister process, and blistering the first hemispherical cap through the three-dimensional ball cap blister device and a preset blister mold to obtain a second hemispherical cap; the preset blister mold is a blister mold with a topographic structure and blister holes; injecting the target material into the pre-molded material through an injection molding process An injection mold is provided for injection molding to obtain a first hemisphere bladder; the injection mold is preset as an injection mold with a topographic structure; a plurality of vacuum holes are punched on the first hemisphere bladder to obtain a second hemisphere bladder; a target adhesive of a preset thickness is applied on the first side of the second hemisphere cap, and the second hemisphere cap applied with the target adhesive is fitted with the second hemisphere bladder to obtain a first hemisphere; the first hemisphere is placed on a ball cap and bladder assembly device, a vacuum negative pressure device is used to apply negative pressure to the first hemisphere, and a high-pressure and high-temperature steam device is used to heat and pressurize the first hemisphere to obtain a second hemisphere; a third hemisphere is obtained; the third hemisphere is opposite to the second hemisphere; and the second hemisphere and the third hemisphere are combined to obtain a target three-dimensional globe. In this way, when assembling the ball cap and bladder, the first hemisphere is firstly applied negative pressure by the vacuum negative pressure device, and then heated and pressurized by the high-pressure and high-temperature steam device, and the obtained second hemisphere is combined into a three-dimensional globe, so that a high-quality three-dimensional globe can be produced at a low cost.
[0032] See also Figure 1 , Figure 1 1 is a flow chart of a method for making a three-dimensional globe provided in an embodiment of the present application. The method is applied to a three-dimensional globe making device. The three-dimensional globe making device includes a three-dimensional ball cap blister device and a ball cap bladder assembly device. The ball cap bladder assembly device includes a vacuum negative pressure device and a high-pressure and high-temperature steam device. The method includes but is not limited to the following steps:
[0033] S101, forming a target printed sheet into a first hemispherical cap by a blister process, and forming the first hemispherical cap by blister forming the three-dimensional hemispherical cap blister device and a preset blister mold to obtain a second hemispherical cap.
[0034] In the embodiment of the present application, the target printed sheet is a sheet used to make a hemispherical cap, and the surface of the sheet is printed with terrain patterns and graphic information required for making a globe, and the thickness is uniform and the size is appropriate. The material of the target printed sheet may include one of the following: PVC plastic, polyethylene (PE) plastic, ethylene-vinyl acetate copolymer (EVA) plastic, ABS plastic, etc., which are not limited here.
[0035] In a specific embodiment, the target printed sheet can be a PVC sheet with a diameter of 320MM. The target printed sheet can be formed into a hemispherical cap through a blister process to obtain a first hemispherical cap. The first hemispherical cap can be formed into a hemispherical cap with a three-dimensional terrain structure through a three-dimensional cap blister device to obtain a second hemispherical cap.
[0036] It should be noted that the three-dimensional terrain structure indicates that the surface of the hemispherical cap has an undulating shape, and these undulating shapes include terrain features such as mountains, rivers, and plains, and these terrain features can be accurately blistered from the blister mold to the hemispherical cap through the high temperature and negative pressure in the blister process, so that the surface of the hemispherical cap presents a three-dimensional effect corresponding to the terrain. The method for making the three-dimensional globe of the present application can not only be used to make a three-dimensional model of the earth's shape, but also can be used to make three-dimensional models of other celestial bodies such as Mars and Venus. The three-dimensional globe made by the method for making the three-dimensional globe of the present application can show the natural landforms of the celestial body in a three-dimensional form, so that the observer can intuitively feel the ups and downs of the surface of the celestial body, which provides a powerful tool for geography teaching and popularization of geographical knowledge.
[0037] The three-dimensional ball cap blister device refers to a device for blistering a first hemispherical cap in a hemispherical shape into a second hemispherical cap with a three-dimensional topographic structure, see Figure 2 , Figure 2 is a structural schematic diagram of a three-dimensional ball cap blister device provided in an embodiment of the present application, such as Figure 2 As shown, the three-dimensional ball cap blister device 200 includes a steam generating device 201 and a vacuum device 202, wherein the ventilation pipe of the steam generating device 201 is connected to the top of the three-dimensional ball cap blister device 200, the steam generating device 201 is used to generate steam with a moderate temperature to heat and soften the hemispherical cap to be blistered, and the vacuum device 202 is connected to the bottom of the three-dimensional ball cap blister device 200 through a pipe, and the vacuum device 202 is used to form a negative pressure environment during the blister process to enable the softened hemispherical cap to closely fit the topographic structure of the blister mold.
[0038] When the hemispherical cap is formed by the three-dimensional ball cap forming device 200, it is first necessary to put the pre-made forming mold into the interior of the three-dimensional ball cap forming device 200, and then put the hemispherical cap on the forming mold, wherein it is necessary to position the hemispherical cap according to the topographic pattern on the hemispherical cap and the topography on the forming mold so that the hemispherical cap is facing the topography for forming. After starting the three-dimensional ball cap forming device 200, the steam generating device 201 first generates steam at a temperature of 85°C to heat and soften the hemispherical cap to make it plastic, and then the vacuum device 202 is started to form negative pressure through the forming holes on the forming mold, so that a negative pressure environment is generated inside the forming mold, and the softened hemispherical cap gradually adheres to the surface of the forming mold under the action of atmospheric pressure to form a hemispherical cap with a three-dimensional topographic structure.
[0039] In the embodiment of the present application, the first hemispherical cap can be formed by the three-dimensional spherical cap forming device and the preset forming mold to obtain the second hemispherical cap with a three-dimensional topographic structure.
[0040] Among them, the preset blister mold is a blister mold with a terrain structure and blister holes, and its terrain structure is opposite to the terrain structure on the hemispherical cap to be blistered. For example, if the hemispherical cap is to show the effect of a mountain bulge, the corresponding position of the preset blister mold is designed as a groove, and vice versa, to ensure that the hemispherical cap can form a correct three-dimensional terrain during the blister process. The preset blister mold is made of a durable metal material with good thermal conductivity, such as metal copper, etc., which is not limited here. At the same time, a suitable number of blister holes are punched on the preset blister mold. The distribution and size of the blister holes are determined according to the specific design of the blister mold and the requirements of the blister process. These blister holes can be accurately drilled or milled into the mold material through CNC machining technology. These blister holes are used to form negative pressure during the blister process, so that the hemispherical cap can fit closely to the terrain structure of the preset blister mold, ensuring that the hemispherical cap forms a three-dimensional terrain, and can also facilitate demolding and reduce damage to the molded hemispherical cap.
[0041] See also Figure 3 , Figure 3 is a schematic diagram of a second hemispherical cap provided in an embodiment of the present application, such as Figure 3 As shown, the hemispherical cap numbered 31 represents the second hemispherical cap of the northern hemisphere of the earth, and the hemispherical cap numbered 32 represents the second hemispherical cap of the southern hemisphere of the earth. The second hemispherical cap 31 of the northern hemisphere and the second hemispherical cap 32 of the southern hemisphere can accurately correspond to the geographical features of the earth. Among them, each hemispherical cap accurately depicts the terrain structure of corresponding scale, including geographical features such as mountains, rivers, and plains.
[0042] Optionally, the method may further include the following steps:
[0043] Acquire first terrain data; establish a first terrain model based on the first terrain data; enlarge the terrain height of the first terrain model based on a preset enlargement ratio to obtain a second terrain model; make a first blister mold and the preset injection mold based on the second terrain model; punch a plurality of blister holes on the first blister mold to obtain the preset blister mold.
[0044] Among them, the preset magnification ratio refers to the scale used when converting the terrain height of the digital model to the terrain height on the globe model, which determines the degree of magnification or reduction of the terrain height on the globe model relative to the terrain height of the digital model. For example, if the preset magnification ratio is 50, it means that the terrain height of the digital model is magnified 50 times. It should be noted that if a three-dimensional globe corresponding to the earth is made, after the digital model of the earth is established, when the digital model of the earth is scaled according to the size of the globe model, the terrain height on the digital model of the earth will also be scaled proportionally. At this time, because the scaling ratio of the digital model of the earth is too large, the structure of the terrain cannot be well observed after the terrain is scaled. Therefore, the terrain height on the digital model of the earth is enlarged according to the preset magnification ratio, so that the terrain structure can be better observed. Of course, the enlarged terrain is a terrain with special reference significance, such as the highest peak on the earth, Mount Everest. The preset magnification ratio can be set according to the specific situation.
[0045] In a specific embodiment, to make a three-dimensional globe corresponding to the earth, it is necessary to first make a corresponding blister mold and injection mold. Specifically, the first terrain data of the earth can be obtained from a network database or a local database. The first terrain data can be a digital elevation model (DEM) data. These data are represented in the form of a grid, and each grid point includes a height value, which reflects the altitude of the corresponding geographical location. Then, a first terrain model can be established according to the digital elevation model data using Geographic Information System (GIS) software or Computer Aided Design (CAD) software. The first terrain model is a three-dimensional model, which includes all terrain features such as mountains, rivers, and plains on the earth.
[0046] Furthermore, the terrain height of the first terrain model is enlarged based on a preset enlargement ratio to obtain a second terrain model, and the first blister mold and the preset injection mold can be manufactured according to the second terrain model. Specifically, computer-aided manufacturing software (CAM) can be used to generate a processing path for the mold according to the second terrain model, and a CNC machine tool can be used to precisely cut the material for making the mold according to the processing path to manufacture the first blister mold and the preset injection mold. Among them, the first blister mold is usually made of a durable metal material with good thermal conductivity, and the preset injection mold is usually made of a high-temperature resistant material such as an aluminum alloy. Wherein, the mold surfaces of the first blister mold and the preset injection mold both have a three-dimensional terrain structure, but the terrain structure of the first blister mold is opposite to the terrain structure on the globe, that is, the protruding part (such as a mountain range) of the globe is a concave part on the first blister mold, and vice versa, while the terrain structure of the preset injection mold is the same as the terrain structure on the globe, that is, the protruding part of the globe is also a protruding part on the preset injection mold, and the purpose is that the first blister mold is to blister a hemispherical hemispherical cap into a hemispherical cap with the same terrain structure as the globe through a blister process, while the preset injection mold is directly injection molded into a hemispherical gallbladder with the same terrain structure as the globe through an injection molding process, and the processing processes are different. Then, a plurality of blister holes are punched on the first blister mold, and specifically, holes can be punched on the concave position of each area on the first blister mold, and the distribution and size of the blister holes can be set according to the specific situation, so that the preset blister mold can be obtained.
[0047] For example, in the process of making a globe of the earth, it is known that the actual diameter of the earth is about 12742 km, and the height of Mount Everest is about 8.848 km. If the diameter of the earth is scaled to 320 MM and a digital model of the earth is established, the terrain height of Mount Everest in the digital model is about 0.222 MM. At this time, the recognizability of the terrain structure on the digital model is low, and Mount Everest is a landmark terrain on the earth. When making a globe, the terrain can be enlarged based on a preset magnification ratio to enhance the intuitiveness of the terrain features of Mount Everest. For example, the terrain height of Mount Everest can be enlarged to 8.48 MM. At this time, the preset magnification ratio can be obtained to be about 38. By enlarging the terrain according to the preset magnification ratio, the terrain structure can be better observed on the globe.
[0048] S102, injecting the target material into a preset injection mold through an injection molding process to obtain a first hemispherical bladder.
[0049] Among them, the preset injection mold is an injection mold with a topographic structure, and its topographic structure is the same as the topographic structure on the globe. By injecting the material used for injection molding into the preset injection mold, a hemispherical bladder with a topographic structure can be obtained.
[0050] In the embodiment of the present application, a target material for injection molding is selected, and the target material can be ABS plastic, resin, etc. The target material is injected into a preset injection mold for injection molding through an injection molding process to obtain a first hemisphere bladder. In a specific embodiment, ABS plastic is selected for injection molding, and ABS plastic pellets can be added to the hopper of an injection molding machine, and the pellets can be heated to a molten state by the heating system of the injection molding machine, wherein the injection molding machine refers to an important industrial equipment for the production of plastic products, which injects plastic materials into the cavity of a closed mold by heating and pressure, and forms a plastic product of a desired shape and size after cooling. When the pellets are heated to a molten state, the injection molding machine is started, and the molten ABS plastic is injected into the cavity of a preset injection mold under high pressure, wherein, in order to ensure that the ABS plastic can be evenly filled into the preset injection mold and reduce the internal stress after molding, the preset injection mold can be preheated to an appropriate temperature, which can generally be 80 to 100 ° C. The pressure and speed of the injection molding machine can be adjusted accordingly according to the characteristics of the target material and the design of the preset injection mold, so that the target material can be evenly filled into each angle of the preset injection mold and form the desired three-dimensional terrain structure. After the injection molding is completed, the molten plastic is cooled and solidified to obtain a first hemispherical bladder, which is used to support the second hemispherical cap.
[0051] S103, punching a plurality of vacuum holes on the first hemispherical bladder to obtain a second hemispherical bladder.
[0052] In a specific embodiment, the first hemispherical bladder can be fixed on a workbench of a CNC machine tool, and the position where the vacuum hole is to be punched is determined. For example, a vacuum hole can be punched in the depression in each area of the first hemispherical bladder. These vacuum holes are used to ensure that a negative pressure environment is formed between the hemispherical cap and the hemispherical bladder when the hemispherical cap and the hemispherical bladder are assembled, so that the hemispherical cap can fit tightly on the hemispherical bladder to form a globe with a precise three-dimensional terrain structure. After determining the position where the vacuum hole needs to be punched, the CNC machine tool is started to punch the vacuum hole according to the punching position, and finally the second hemispherical bladder can be obtained.
[0053] See also Figure 4 , Figure 4 Schematic diagram of the second hemisphere bladder provided in the embodiment of the present application, Figure 4As shown, the hemispherical bladder numbered 41 represents the second hemispherical bladder of the northern hemisphere of the earth, and the hemispherical bladder numbered 42 represents the second hemispherical bladder of the southern hemisphere of the earth. Each hemispherical bladder accurately depicts a terrain structure of a corresponding scale, including mountains, rivers, plains and other geographical features. The second hemispherical bladder 41 of the northern hemisphere and the second hemispherical bladder 42 of the southern hemisphere are both provided with vacuum holes, which are used to remove the air between the hemispherical cap and the hemispherical bladder in the subsequent bonding process to ensure a tight fit between the hemispherical cap and the hemispherical bladder.
[0054] S104, applying a target adhesive of a preset thickness on the first side of the second hemispherical cap, and fitting the second hemispherical cap coated with the target adhesive with the second hemispherical bladder to obtain a first hemispherical body.
[0055] The first side is the inner surface of the second hemispherical cap. The target adhesive includes one of the following: hot melt adhesive, self-adhesive adhesive, which is not limited here. The preset thickness is the preset thickness of the target adhesive coating, and good bonding strength can be achieved under the preset thickness.
[0056] In a specific embodiment, the preset thickness can be 0.02MM, the target adhesive can be self-adhesive, and 0.02MM of self-adhesive is applied to the inner surface of the second hemispherical cap, and then the second hemispherical cap coated with self-adhesive is put on the second hemispherical bladder, so that the second hemispherical cap and the second hemispherical body are preliminarily bonded, and then the first hemispherical body can be obtained.
[0057] Optionally, the method may further include the following steps:
[0058] The target adhesive of the preset thickness is applied to the second side of the second hemispherical bladder, and the second hemispherical cap is fitted onto the second hemispherical bladder coated with the target adhesive to obtain the first hemispherical body.
[0059] The second side is the outer surface of the second hemispherical bladder.
[0060] In a specific embodiment, the preset thickness can be 0.02MM, the target adhesive can be a self-adhesive sticker, and 0.02MM of self-adhesive sticker is applied on the outer surface of the second hemispherical bladder, and then the second hemispherical cap is put on the second hemispherical bladder coated with self-adhesive sticker, so that the second hemispherical cap and the second hemispherical body are preliminarily bonded, and then the first hemispherical body can be obtained.
[0061] S105, placing the first hemisphere on the ball cap and bladder assembly device, applying negative pressure to the first hemisphere by the vacuum negative pressure device, and heating and pressurizing the first hemisphere by the high-pressure and high-temperature steam device to obtain a second hemisphere.
[0062] Among them, the ball cap and bladder assembly device refers to a device for tightly combining the first hemispherical body, which first uses a vacuum negative pressure device to apply negative pressure to the vacuum hole on the second hemispherical bladder, and then heats and pressurizes the second hemispherical cap through a high-pressure and high-temperature steam device to soften the second hemispherical cap. At the same time, the second hemispherical cap and the second hemispherical bladder form a tight bond under the combined action of negative pressure and the target adhesive. Specifically, the vacuum negative pressure effect and the viscosity of the target adhesive jointly promote the tight fit between the second hemispherical cap and the second hemispherical bladder, thereby obtaining a tightly combined second hemispherical body.
[0063] See also Figure 5 , Figure 5 is a structural schematic diagram of a ball cap and bladder assembly device provided in an embodiment of the present application, such as Figure 5 As shown, the ball cap and bladder assembly device 500 includes a high-pressure and high-temperature steam device 501 and a vacuum negative pressure device 502, wherein the high-pressure and high-temperature steam device 501 is used to heat the hemispherical cap, and can generate steam with a temperature of 85 to 130°C, and the steam pressure is 1 to 2 standard atmospheres, and the vacuum negative pressure device 502 is used to apply negative pressure to the vacuum holes on the hemispherical bladder to form a tight fit between the hemispherical cap and the hemispherical bladder.
[0064] When assembling the hemispherical cap and the hemispherical bladder through the cap and bladder assembly device 500, the hemispherical body composed of the hemispherical cap and the hemispherical bladder is placed on the cap and bladder assembly device 500, and the vacuum negative pressure device 502 is first started to apply negative pressure to the vacuum hole on the hemispherical bladder to make the hemispherical cap and the hemispherical bladder fit preliminarily. At the same time, the terrain structure on the hemispherical cap is prevented from being deformed when the hemispherical cap is heated and pressurized. Then, the high-pressure and high-temperature steam device 501 is started to generate steam of set temperature and pressure, and the steam is introduced into the cap and bladder assembly device 500 through the ventilation pipe. The steam can be evenly distributed on the surface of the cap to achieve comprehensive and uniform heating and pressurization. When the hemispherical cap reaches a softened state, the hemispherical cap and the hemispherical bladder can fit tightly due to the negative pressure effect between the hemispherical cap and the hemispherical bladder and the bonding effect of the target adhesive. When assembling the hemispherical cap and the hemispherical bladder, the ball cap and bladder assembly device 500 first performs vacuum negative pressure, and then introduces steam under negative pressure conditions to heat and pressurize, which can improve production efficiency and ensure the quality and result stability of the three-dimensional globe.
[0065] In a specific embodiment, the first hemisphere is placed on a ball cap and bladder assembly device, and the first hemisphere is first subjected to negative pressure by a vacuum negative pressure device, and then heated and pressurized by a high-pressure and high-temperature steam device. In the steam environment, the hemisphere cap gradually reaches the glass transition temperature and enters a softened state. Due to the negative pressure between the hemisphere cap and the hemisphere bladder, the hemisphere cap is always attached to the hemisphere bladder. Finally, the topographic structure on the hemisphere cap and the hemisphere bladder fits tightly, and then the second hemisphere can be obtained.
[0066] Optionally, the above step S105, placing the first hemisphere on the ball cap and bladder assembly device, applying negative pressure to the first hemisphere by the vacuum negative pressure device, and heating and pressurizing the first hemisphere by the high-pressure and high-temperature steam device to obtain the second hemisphere, may include the following steps:
[0067] S51, determining a first negative pressure value for negative pressure and a first steam parameter of steam passed into the ball cap and bladder assembly device;

[0076] The preset first vacuum degree threshold refers to a preset minimum value or critical value of the vacuum degree, which is used to determine whether the vacuum chamber in the ball cap and bladder assembly device has reached a sufficient vacuum condition, under which the second hemispherical cap and the second hemispherical bladder on the first hemispherical body are preliminarily fitted to prevent the second hemispherical cap from deforming due to loose fitting. The vacuum degree indicates the negative pressure level in the container, which can also indicate the vacuum degree in the vacuum container, usually in Pascal (Pa), millibar (mbar) or Torr. When measuring, a McLaren vacuum gauge, a thermocouple vacuum gauge, a Pirani vacuum gauge or a cold cathode ionization vacuum gauge can be used for measurement, and the measured value is displayed on a vacuum meter.
[0077] In the embodiment of the present application, the steam parameters set in the high-temperature and high-pressure steam device may include at least one of the following: steam temperature, steam pressure, steam flow rate, steam humidity, steam distribution uniformity, etc., which are not limited here.
[0078] In the embodiment of the present application, the target state information may include at least one of the following: temperature, pressure, humidity, shape, degree of completion, etc., which are not limited here.
[0079] In a specific embodiment, a first negative pressure value for negative pressure and a first steam parameter of steam passed into a ball cap and bladder assembly device are determined, and a vacuum negative pressure device is used to apply negative pressure to the first hemisphere according to the first negative pressure value, so that the second hemisphere cap and the second hemisphere bladder can be preliminarily fitted, so as to promote the contact between the second hemisphere cap and the second hemisphere bladder, and prevent the second hemisphere cap from deforming during heating and pressurization. The current target vacuum degree can be obtained through the vacuum gauge on the vacuum negative pressure device. When the target vacuum degree is greater than or equal to the preset first vacuum degree threshold, it can be determined that the second hemisphere cap and the second hemisphere bladder have been fitted together, and then steam can be generated through a high-pressure and high-temperature steam device, and the first hemisphere can be heated and pressurized by steam to soften the second hemisphere cap, so that the second hemisphere cap is completely fitted on the second hemisphere bladder.
[0080] Specifically, a high-pressure and high-temperature steam device generates first steam according to a first steam parameter, and the first steam is passed into a ball cap and bladder assembly device, wherein the first steam is used to heat and pressurize the first hemisphere. When the first hemisphere is in a first preset condition, that is, the temperature of the first hemisphere rises, the second hemisphere cap reaches the glass transition temperature of the material, the second hemisphere cap begins to glass transition and gradually softens, and under the continuous vacuum negative pressure, the softened second hemisphere cap is bonded to the second hemisphere bladder. At this time, it can be determined that the bonding state of the first hemisphere is good. Since the second hemisphere cap and the second hemisphere bladder are in close contact and there is no obvious gap or misalignment, the subsequent bonding firmness and overall performance improvement are ensured.
[0081] Furthermore, after the first hemisphere reaches a preliminary fitting state, its target state information can be obtained through a sensor, and the first steam parameter can be adjusted according to the target state information to obtain a second steam parameter. A second steam is generated according to the second steam parameter through a high-pressure and high-temperature steam device, and the second steam is introduced into the ball cap bladder assembly device. When the first hemisphere is in a second preset condition, that is, when the second hemisphere cap reaches the final fitting temperature and becomes completely softened, the introduction of the second steam is stopped until the first hemisphere is cooled, and the second hemisphere can be obtained.
[0082] It should be noted that in the embodiment of the present application, the first hemisphere is firstly continuously subjected to negative pressure by a vacuum negative pressure device to ensure that under the action of the vacuum negative pressure, the second hemisphere cap and the second hemisphere bladder are initially fitted together and the second hemisphere cap does not deform during the softening process. Then, steam is introduced into the ball cap and bladder assembly device through a high-pressure and high-temperature steam device to gradually soften the second hemisphere cap, and the topographic structure on the second hemisphere cap and the topographic structure on the second hemisphere bladder are closely fitted until the fit reaches an ideal state, and then the high-pressure and high-temperature steam device is turned off and the steam is stopped. In order to prevent the topographic structure on the second hemisphere cap from deforming during the cooling period when the first hemisphere is cooled, the first hemisphere can also continue to be subjected to negative pressure until the first hemisphere is completely cooled, and then a second hemisphere with a stable structure can be obtained.
[0083] For example, the first hemisphere is placed on the ball cap and bladder assembly device, and then the first negative pressure value of the vacuum negative pressure device is set to 0.9 standard atmospheric pressure, and the first steam parameters of the high-pressure and high-temperature steam device are set to 90°C and 1.1 standard atmospheric pressure. The first hemisphere is subjected to negative pressure operation through the vacuum negative pressure device. Since the second hemisphere bladder has a vacuum hole, a vacuum negative pressure environment is formed between the second hemisphere cap and the second hemisphere bladder, so that the second hemisphere cap and the second hemisphere bladder are preliminarily fitted. After it is determined that the second hemisphere cap and the second hemisphere bladder are well fitted, steam is introduced through the high-pressure and high-temperature steam device to heat the second hemisphere cap. Pressurize until the first hemisphere reaches a good fit state. At this time, the second hemisphere cap undergoes a glass transition, and the topographic structure on the second hemisphere cap begins to align with the topographic structure on the second hemisphere bladder. However, because the second hemisphere cap has not completely softened, the first steam parameter of the high-pressure and high-temperature steam device is adjusted to obtain the second steam parameter. The second steam parameter is 100°C and 1.3 standard atmospheric pressures. The steam generated based on the second steam parameter can completely soften the second hemisphere cap, thereby making the topographic structure on the second hemisphere cap completely fit with the topographic structure on the second hemisphere bladder, that is, the first hemisphere is tightly fitted. In this way, a high-quality fitted and cured second hemisphere can be obtained for making an accurate three-dimensional globe.
[0084] Optionally, the first preset condition includes: the temperature of the first hemisphere is within a first preset temperature range; the first preset temperature range is 75-80°C; the second preset condition includes: the temperature of the first hemisphere is within a second preset temperature range; the second preset temperature range is 80-85°C.
[0085] In a specific embodiment, when the first hemisphere is in a first preset condition, that is, the temperature of the first hemisphere is in a first preset temperature range, which may be 75-80°C, it indicates that the first hemisphere has reached the temperature required for the vitrified state. At this temperature, it indicates that the second hemisphere cap and the second hemisphere bladder on the first hemisphere have been bonded under negative pressure and heating and pressurization. However, in this case, the bonding effect fails to achieve the expected effect. Therefore, the steam parameters of the high-pressure and high-temperature steam device may be changed to generate steam that can soften the second hemisphere cap. Under the action of this steam, until the first hemisphere is in a second preset condition, that is, the temperature of the first hemisphere is in a second preset temperature range, which may be 80-85°C, it indicates that the first hemisphere has reached the temperature required for the softened state. At this temperature, the second hemisphere cap softens and fits tightly with the second hemisphere bladder.
[0086] Optionally, the target state information includes temperature. The above step S57, adjusting the first steam parameter according to the target state information to obtain the second steam parameter, may include the following steps:
[0087] Acquire a first temperature of the first hemisphere; determine a target temperature of the first hemisphere; determine a target adjustment coefficient according to a difference between the first temperature and the target temperature; and adjust the first steam parameter according to the target adjustment coefficient to obtain a second steam parameter.
[0088] In a specific embodiment, the target state information may be temperature, and the first steam parameter may be adjusted according to the temperature information of the first hemisphere, thereby obtaining the second steam parameter. Specifically, the surface temperature of the first hemisphere may be measured by a temperature measuring device to obtain the first temperature, and the target temperature of the first hemisphere may be determined, wherein the target temperature may be a temperature set according to the material of the second hemisphere cap, and when the second hemisphere cap reaches the target temperature, the second hemisphere cap may soften, and then the fitting operation may be performed. The target adjustment coefficient may be determined according to the difference between the first temperature and the target temperature, and the difference is proportional to the target adjustment coefficient, and the larger the difference, the larger the target adjustment coefficient. The second steam parameter may be obtained by adjusting the first steam parameter according to the target adjustment coefficient, and the high-pressure and high-temperature steam device generates steam based on the second steam parameter, and the steam generated by the high-pressure and high-temperature steam device may soften the second hemisphere cap on the first hemisphere, so that the second hemisphere cap may be closely fitted to the second hemisphere bladder.
[0089] S106: Obtain a third hemisphere.
[0090] In a specific embodiment, the third hemisphere can be manufactured through the above steps, wherein the third hemisphere is opposite to the second hemisphere, and both the second hemisphere and the third hemisphere are manufactured through the above process steps. For example, when manufacturing a three-dimensional globe of the earth, the second hemisphere can represent the northern hemisphere of the earth, which is manufactured by a preset blister mold and a preset injection mold designed specifically for the terrain of the northern hemisphere. The mold is processed based on the terrain data of the northern hemisphere, and it can highly restore various terrain and geomorphic features of the northern hemisphere. Similarly, the third hemisphere can represent the southern hemisphere of the earth, which is manufactured by a preset blister mold and a preset injection mold designed specifically for the terrain of the southern hemisphere. The mold is processed based on the terrain data of the southern hemisphere, and it can highly restore various terrain and geomorphic features of the southern hemisphere.
[0091] Of course, the second hemisphere can also represent the Eastern Hemisphere, and correspondingly, the third hemisphere represents the Western Hemisphere, which are all made through the above process steps. By seamlessly combining the second hemisphere and the third hemisphere into one, a complete and high-precision three-dimensional globe can be constructed, whose surface topography structure is complete and continuous, and whose geographical features are clearly identifiable, and can be used for geography teaching, scientific research display and professional analysis.
[0092] S107, combining the second hemisphere and the third hemisphere to obtain a target three-dimensional globe.
[0093] In a specific embodiment, the joint surfaces of the second hemisphere and the third hemisphere are ensured to be precisely matched so that the second hemisphere and the third hemisphere can be seamlessly connected. Then, an adhesive can be evenly applied to the joint edges of the two hemispheres. By aligning and combining the two hemispheres, a target three-dimensional globe can be obtained.
[0094] The adhesive may be epoxy resin or other industrial adhesives with strong weather resistance and high temperature resistance. The adhesive is evenly applied to the joint edge of the second hemisphere and the third hemisphere. During the curing period of the adhesive, the two hemispheres are kept fixed. After sufficient curing, the second hemisphere and the third hemisphere are tightly combined together to form a high-quality target three-dimensional globe with a topographic structure.
[0095] Optionally, the above step S107, combining the second hemisphere and the third hemisphere to obtain the target three-dimensional globe, may include the following steps:
[0096] The second hemisphere and the third hemisphere are trimmed and arranged respectively to obtain the fourth hemisphere and the fifth hemisphere; multiple first pairing points on the fourth hemisphere are determined; multiple second pairing points on the fifth hemisphere are determined; the second pairing points correspond to the first pairing points one by one; the fourth hemisphere and the fifth hemisphere are combined according to the alignment of the multiple first pairing points and the multiple second pairing points to obtain the target three-dimensional globe.
[0097] In a specific embodiment, the second hemisphere and the third hemisphere need to be trimmed after forming to ensure the accuracy and smoothness of the edges of the hemispheres. When trimming, a cutting device such as a water jet or a laser cutter can be used to cut along the edge of each hemisphere to remove excess material and burrs, and obtain a fourth hemisphere and a fifth hemisphere with precise and smooth edges. By trimming the second hemisphere and the third hemisphere, the sealing and aesthetics of the target globe obtained by combining the two hemispheres can be ensured.
[0098] Furthermore, in order to ensure that the fourth hemisphere and the fifth hemisphere can be precisely aligned and combined, multiple first alignment points on the fourth hemisphere can be determined, and multiple second alignment points on the fifth hemisphere can be determined, wherein the second alignment points correspond one-to-one to the first alignment points. It should be noted that these alignment points are marks set on the combined edges of the hemispheres, which can be grooves, convex points or marks of special shapes. These alignment points are optimized according to the geometric features of the hemispheres and the shape of the combined surfaces, so that when the two hemispheres are combined, the hemispheres are aligned according to these precisely corresponding alignment points to improve stability and accuracy during the combination process.
[0099] Next, the fourth hemisphere and the fifth hemisphere are aligned and combined according to the multiple first pairs of points on the fourth hemisphere and the multiple second pairs of points on the fifth hemisphere. After the alignment is completed, the selected adhesive (such as epoxy resin) is evenly applied along the combined edge, and then the two hemispheres are fixed together. When the adhesive is cured, the joints of the globe can be polished and modified to achieve a smooth and beautiful appearance. Finally, a target three-dimensional globe with precise combination and stable structure can be obtained. The surface of the target three-dimensional globe has three-dimensional terrain structure features and can be used for geography teaching and display functions.
[0100] Among them, the manufacturing method of the target three-dimensional globe in the embodiment of the present application is simple to implement, effective and has a low scrap rate, especially the close connection between the ball cap and the ball bladder without any gaps, so that the three-dimensional effect of the target three-dimensional globe is accurate and clear, and the delicate texture of the mountains can be seen, providing a useful teaching aid for middle school geography teaching.
[0101] In summary, by implementing the embodiments of the present application, the printed sheet is made into a hemispherical cap by the blister process, and is formed by a blister mold to obtain a hemispherical cap with a topographic structure; then a hemispherical bladder with a topographic structure is produced by the injection molding process, and a vacuum hole is punched on it; an adhesive is applied to the hemispherical cap and it is fitted with the hemispherical bladder to form a hemispherical body; then a vacuum negative pressure device is used to apply negative pressure, and then a high-pressure and high-temperature steam device is used to heat and pressurize, so that a tightly fitting hemispherical body can be obtained; according to this method, two opposite hemispherical bodies can be produced, and the two hemispherical bodies can be combined to form a complete three-dimensional globe. In this way, a high-quality three-dimensional globe can be produced at a low cost.
