Description

Technical Field

[0001] This invention relates to the field of printing and molding equipment technology, specifically a desktop photopolymer printing and molding device. Background Technology

[0002] Energetic materials are a class of special functional materials with chemical reactivity that can release a large amount of energy. Their energy density and reaction stability directly determine the performance limit of downstream equipment. As advanced equipment develops towards "long-range, high precision, and high reliability", it puts forward the core requirements of high specific impulse, high density, adjustable thrust, and complex structure for energetic materials. However, traditional molding technologies (such as compression molding and casting molding) are difficult to achieve precise manufacturing of complex structures, and the stability of materials is easily damaged by external forces during processing. Therefore, it is urgent to innovate manufacturing technologies to break through the bottleneck.

[0003] Printing molding equipment is mainly used for photocuring energetic materials. Due to the special nature of energetic materials, it is necessary to control the extrusion pressure during extrusion to prevent excessive extrusion from causing frictional heat inside the energetic material, which may lead to slow decomposition and affect the overall stability of the energetic material. In addition, during the photocuring process, the ultraviolet light generated may irradiate the output end of the extrusion device, which may cause the material at the output end to solidify, affecting the extrusion speed and material stability. Summary of the Invention

[0004] The purpose of this invention is to provide a desktop photopolymerization printing device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The printing molding equipment includes a base assembly, a housing assembly, and a platform assembly. The housing assembly is located at the top of the base assembly, and the platform assembly is located inside the housing assembly. An extrusion assembly is located at the top of the platform assembly, and illumination assemblies are located on both sides of the platform assembly. An adjustment assembly is located inside the illumination assembly to control the illumination angle of the illumination assembly. A detection assembly is located inside the extrusion assembly to adjust the extrusion pressure of the extrusion assembly.

[0006] Furthermore, the photopolymerization equipment is mainly used for photopolymerization of energetic materials, including semi-solids and liquids. Semi-solid materials require kneading before photopolymerization, followed by placing the kneaded material into an extrusion device for plasticization. Then, ultraviolet light is used to cure the material. Due to the special properties of energetic materials, the extrusion pressure needs to be controlled during extrusion to prevent excessive extrusion from generating frictional heat within the material, which could lead to slow decomposition and affect the overall stability of the energetic material. Additionally, the ultraviolet light generated during photopolymerization illuminates the output end of the extrusion device, accelerating the output process. The solidification rate of the material at the end affects the extrusion speed and material stability. The base assembly supports the device on the table. The shell assembly prevents external particles from affecting the internal energetic material and also prevents the energetic material from exploding and affecting external personnel. The extrusion assembly controls the movement of the extrusion head through a drive, so that the extruded material forms the set shape. The platform assembly controls the rotation of the material, thereby improving the efficiency of photocuring. The illumination assembly is used to irradiate the material with ultraviolet light. The adjustment assembly is used to adjust the intensity of ultraviolet light to adapt to different thicknesses and positions. The detection assembly is used to monitor the pressure on the material at the output end of the extrusion device.

[0007] The base assembly includes a base plate and feet. The feet are located on a horizontal tabletop, and the base plate is located at the top of the feet. The base plate is fixedly connected to the feet, and the upper surface of the base plate has a mounting groove.

[0008] Furthermore, there are four feet located at the four corners of the base plate. The top of the feet is fixedly connected to the bottom of the base plate. The upper surface of the base plate is provided with a mounting groove. The inner wall of the mounting groove is used for the housing assembly to fit together, and the bottom of the inner wall of the mounting groove is used for installing parts.

[0009] The platform components include a rotating motor, a transmission wheel assembly, and a support column. The rotating motor is located at the top of the base plate. The output end of the rotating motor is equipped with a transmission wheel assembly. The top of the transmission wheel assembly is equipped with a support column, which is fixedly connected to the bottom of the support column. The top of the support column is equipped with a worktable, which is fixedly connected to the top of the support column. A placement groove is opened on the upper surface of the worktable. The resistance wire is located at the bottom of the inner wall of the placement groove and is fixedly connected to the inner wall of the placement groove. A tabletop is located at the top of the resistance wire. The top of the tabletop is made of silicone, and the bottom of the tabletop is made of shape memory alloy.

[0010] Furthermore, the rotating motor serves as the power source to control the rotation of the transmission wheel assembly. The rotation of the transmission wheel assembly drives the support column to rotate, which in turn drives the worktable to rotate, causing the material on the upper surface of the worktable to rotate accordingly. This increases the angle range of light irradiation that the material can receive. The placement groove on the upper surface of the worktable is used to engage with the table panel. The two ends of the resistance wire are electrically connected to an external power source. Before the extrusion assembly operates, the table panel is in the placement groove, and the extruded material falls onto the table panel. Then, after the photocuring is completed, the resistance wire is energized and generates a small amount of heat. Because the resistance wire is located at the bottom of the table panel, the shape memory alloy surface at the bottom of the table panel comes into contact with the resistance wire first and bends due to the heat. Ultimately, the entire table panel bends slightly. Since the surface of the table panel is made of silicone, it provides a heat insulation effect, significantly reducing the impact of heat on the bottom of the molded material. This makes it easier for workers to pick up the molded material without the need for additional tools.

[0011] The lighting assembly includes a column and UV curing lamps. The bottom of the column is fixedly connected to the base plate. A UV curing lamp is installed on the side of the column close to the workbench. There are several UV curing lamps, which are arranged at equal intervals. An adjustment component is provided on the column.

[0012] Furthermore, there are two columns, located on both sides of the support column. The bottom of the columns is fixedly connected to the upper surface of the base plate. The two columns are equipped with UV curing lamps on the side close to the support column. The UV curing lamps are mainly used to provide ultraviolet light to irradiate the material, thereby curing the material in the irradiated area. The adjustment component is mainly used to adjust the intensity and range of the light.

[0013] The adjustment assembly includes an auxiliary lamp, a connecting base, and a rotating block. The connecting base is located on both sides of the light curing lamp, and the auxiliary lamp is rotatably connected to the connecting base. The rotating block is located at the top of the connecting base and is fixedly connected to the auxiliary lamp. A connecting rod is provided at the top of the rotating block and is fixedly connected to the column. Telescopic components are sleeved at both ends of the connecting rod. One end of the telescopic component is rotatably connected to the rotating block, and the other end of the telescopic component is provided with an electromagnet. The telescopic component is slidably connected to the connecting rod.

[0014] Furthermore, the electromagnets are electrically connected to an external power source. When the electromagnets are energized, the two electromagnets attract each other and generate displacement. By controlling the direction of the current, the attraction or repulsion of the electromagnets can be adjusted. The movement of the electromagnets will drive the telescopic rod to move, which in turn will drive the rotating block to rotate. The rotation of the rotating block will adjust the angle of the two auxiliary lamps. When the angle between the auxiliary lamp and the curing lamp is adjusted to 30°, the curing lamp can focus the light. The auxiliary lamp will reflect the scattered light from the edge of the curing lamp back to the center, reducing the diffusion of light in all directions and improving the curing efficiency for thick-walled materials. Then, when the angle between the auxiliary lamp and the curing lamp is adjusted to 60°, the curing lamp can diffuse the light. The constraint of the auxiliary lamp on the light from the edge of the curing lamp is weakened, and more light can diffuse in all directions, ultimately achieving the adjustment of the intensity and range of the curing lamp.

[0015] The extrusion assembly includes an extrusion head, a frame, and a cover. The frame is located on the upper surface of the base plate and is fixedly connected to the base plate. A drive unit is provided at the top of the frame. The drive unit is used to control the movement of the extrusion head. The fixed end of the drive unit is fixedly connected to the frame. A connector is provided at the output end of the drive unit. The extrusion head is provided at the bottom end of the connector. The cover is fitted onto the extrusion head, and the top of the cover is rotatably connected to the connector.

[0016] Furthermore, the frame is located on the upper surface of the base plate, and the bottom end of the frame is fixedly connected to the upper surface of the base plate. The frame is used to support the drive unit, which is existing technology and is mainly used to control the movement of the extrusion head. Then, when the drive unit works, it controls the movement of the connecting parts, and the movement of the connecting parts drives the extrusion head to move. The bottom end of the extrusion head is provided with an output end, which is mainly used to squeeze the material onto the worktable. The cover serves as a second protective device to prevent the material from reacting violently and affecting other components.

[0017] The detection assembly includes a sleeve, a spring, and a scraper. The sleeve is fitted onto the output end of the extruder head, and a spring is provided between the sleeve and the extruder head. A blocking block is provided at the bottom end of the sleeve and is fixedly connected to the bottom end of the sleeve. The scraper is located on the outer wall of the sleeve and is fixedly connected to the sleeve.

[0018] Furthermore, when the extruder is working, the material is discharged through the output end. Since the material is in a semi-solid state, its movement will squeeze the blocking block at the bottom of the sleeve. The movement of the blocking block will drive the sleeve to move, and the movement of the sleeve will stretch the spring. The two ends of the spring are electrically connected to an external power source. When the spring is stretched, its overall length increases and its cross-sectional area decreases, resulting in increased resistance. The higher the resistance, the greater the squeezing pressure on the material. Then, when the curing lamp is in diffused light mode, because the curing lamp has a large irradiation range, it can easily cover the output end of the extruder, causing the material to harden. However, due to the protection of the sleeve, the material hardening is prevented. Finally, after the extruder finishes working, the sleeve is pulled by the spring and moves towards the extruder. As a result, the inner wall of the sleeve will come into contact with the scraper, and the residue will be scraped off without affecting subsequent use.

[0019] The housing assembly includes an outer shell and an observation window. The bottom end of the outer shell is fixedly connected to the base plate. The outer shell has a groove, and the observation window mates with the groove.

[0020] Furthermore, the bottom of the outer shell is fixedly connected to the upper surface of the base plate. The outer shell is used to protect external operators. The outer shell has a groove for observing the materials on the table. The observation window is a transparent plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. During extrusion, the material movement of this invention will squeeze the barrier block at the bottom of the sleeve. The movement of the barrier block will drive the sleeve to move, which will lead to an increase in the overall length of the spring, a decrease in the cross-sectional area, and an increase in resistance. The extrusion pressure is determined based on the resistance value. The sleeve has extensibility while protecting the internal material, preventing the material from being exposed to ultraviolet light, and improving the material flowability.

[0022] 2. In the photocuring process, this invention controls the energization of the electromagnet to rotate the block, thereby adjusting the angle of the two auxiliary lamps. When the angle between the auxiliary lamp and the photocuring lamp is adjusted to 30°, the auxiliary lamp reflects the scattered light from the edge of the photocuring lamp back to the center, achieving focused light from the photocuring lamp. Then, when the angle between the auxiliary lamp and the photocuring lamp is adjusted to 60°, the constraint of the auxiliary lamp on the light from the edge of the photocuring lamp is weakened, achieving diffused light from the photocuring lamp, thus adjusting the irradiation intensity and range.

[0023] 3. After the photocuring process is completed, the resistance wire in the workbench generates a small amount of heat, which causes the shape memory alloy surface at the bottom of the workbench to bend upon contact with the resistance wire. Then, the entire workbench bends slightly, separating the material from the workbench. Furthermore, the silicone material on the surface of the workbench provides insulation, significantly reducing the impact of heat on the bottom of the molded material. This makes it easier for workers to pick up the molded material without the need for additional tools. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figures 1-9 As shown, the present invention provides a technical solution for a desktop photopolymerization printing and molding device. The printing and molding device includes a base assembly 1, a housing assembly 2, and a platform assembly 3. The housing assembly 2 is located at the top of the base assembly 1, and the platform assembly 3 is located inside the housing assembly 2. An extrusion assembly 4 is located at the top of the platform assembly 3, and light-illuminating components 5 are located on both sides of the platform assembly 3. An adjustment component 6 is located inside the light-illuminating component 5. The adjustment component 6 is used to control the irradiation angle of the light-illuminating component 5. A detection component 7 is located inside the extrusion assembly 4. The detection component 7 is used to adjust the extrusion pressure of the extrusion assembly 4.

[0028] Specifically, photopolymerization equipment is mainly used for photocuring energetic materials. Energetic materials include semi-solids and liquids. Before photocuring, the semi-solid materials need to be kneaded and placed in an extrusion device for plasticization. Then, ultraviolet light is used to cure the material. Due to the special properties of energetic materials, the extrusion pressure needs to be controlled during extrusion to prevent excessive extrusion from generating frictional heat inside the material, which could lead to slow decomposition and affect the overall stability of the energetic material. Furthermore, during photocuring, the generated ultraviolet light shines on the output end of the extrusion device, accelerating the curing process at the output end. The solidification speed of the material affects the extrusion speed and material stability. The base assembly 1 is used to support the device to stand on the table. The shell assembly 2 is used to prevent external particles from affecting the internal energetic material and to prevent the energetic material from exploding and affecting external personnel. The extrusion assembly 4 drives the extrusion head 41 to move, so that the extruded material forms the set shape. The platform assembly 3 is used to control the rotation of the material, thereby improving the efficiency of photocuring. The light irradiation assembly 5 is used to irradiate the material with ultraviolet light. The adjustment assembly 6 is used to adjust the intensity of ultraviolet light to adapt to different thicknesses and positions. The detection assembly 7 is used to monitor the pressure on the material at the output end of the extrusion device.

[0029] like Figure 1 , Figure 9 As shown, the base assembly 1 includes a base plate 11 and a foot 12. The foot 12 is located on a horizontal tabletop. The base plate 11 is provided at the top of the foot 12. The base plate 11 and the foot 12 are fixedly connected. An installation groove is provided on the upper surface of the base plate 11.

[0030] Specifically, there are four feet 12 located at the four corners of the base plate 11. The top of the feet 12 is fixedly connected to the bottom of the base plate 11. The upper surface of the base plate 11 is provided with a mounting groove. The inner wall of the mounting groove is used to cooperate with the housing assembly 2, and the bottom of the inner wall of the mounting groove is used to install parts.

[0031] like Figure 2 , Figure 3 , Figure 9 As shown, platform component 3 includes a rotating motor 31, a transmission wheel set 32, and a support column 33. The rotating motor 31 is located at the top of the base plate 11. The output end of the rotating motor 31 is provided with the transmission wheel set 32. The top of the transmission wheel set 32 ​​is provided with the support column 33. The transmission wheel set 32 ​​is fixedly connected to the bottom of the support column 33. The top of the support column 33 is provided with a worktable 34. The top of the support column 33 is fixedly connected to the worktable 34. A placement groove is opened on the upper surface of the worktable 34. The resistance wire 35 is located at the bottom of the inner wall of the placement groove. The resistance wire 35 is fixedly connected to the inner wall of the placement groove. The top of the resistance wire 35 is provided with a table panel 36. The top of the table panel 36 is made of silicone material, and the bottom of the table panel 36 is made of shape memory alloy material.

[0032] Specifically, the rotating motor 31 serves as the power source to control the rotation of the transmission wheel assembly 32. The rotation of the transmission wheel assembly 32 drives the support column 33 to rotate, which in turn drives the worktable 34 to rotate. Consequently, the material on the upper surface of the worktable 34 rotates accordingly, increasing the angle range of light irradiation on the material. The placement groove on the upper surface of the worktable 34 is used to engage with the table panel 36. The two ends of the resistance wire 35 are electrically connected to an external power source. Before the extrusion assembly operates, the table panel 36 is in the placement groove, and the extruded material falls onto the table panel 36. After the photocuring is completed, the resistance wire 35 is energized, generating a small amount of heat. Since the resistance wire 35 is located at the bottom of the table panel 36, the shape memory alloy surface at the bottom of the table panel 36 comes into contact with the resistance wire 35 first, causing it to bend due to heat. Ultimately, the entire table panel 36 bends slightly. Because the surface of the table panel 36 is made of silicone, it provides heat insulation, significantly reducing the impact of heat on the bottom of the molded material. This makes it easier for workers to pick up the molded material without the need for additional tools.

[0033] like Figure 3 , Figure 6 As shown, the lighting component 5 includes a column 51 and a light curing lamp 52. The bottom end of the column 51 is fixedly connected to the base plate 11. A light curing lamp 52 is provided on the side of the column 51 close to the workbench 34. There are several light curing lamps 52, which are arranged at equal intervals. An adjustment component 6 is provided on the column 51.

[0034] Specifically, there are two columns 51, which are located on both sides of the support column 33. The bottom end of the column 51 is fixedly connected to the upper surface of the base plate 11. The two columns 51 are equipped with a light curing lamp 52 on the side close to the support column 33. The light curing lamp 52 is mainly used to provide ultraviolet light and irradiate the material, thereby curing the material in the irradiated area. The adjustment component 6 is mainly used to adjust the light intensity and range.

[0035] like Figure 6 , Figure 7 As shown, the adjustment component 6 includes an auxiliary lamp 61, a connecting seat 62, and a rotating block 63. The connecting seat 62 is located on both sides of the light curing lamp 52. The auxiliary lamp 61 is rotatably connected to the connecting seat 62. The rotating block 63 is located at the top of the connecting seat 62 and is fixedly connected to the auxiliary lamp 61. A connecting rod 64 is provided at the top of the rotating block 63. The connecting rod 64 is fixedly connected to the column 51. Telescopic members 65 are sleeved at both ends of the connecting rod 64. One end of the telescopic member 65 is rotatably connected to the rotating block 63, and the other end of the telescopic member 65 is provided with an electromagnet 66. The telescopic member 65 is slidably connected to the connecting rod 64.

[0036] Specifically, electromagnet 66 is electrically connected to an external power source. When electromagnet 66 is energized, the two electromagnets 66 attract each other and generate displacement. By controlling the direction of the current, the attraction or repulsion of electromagnets 66 is adjusted. The movement of electromagnet 66 drives the telescopic rod to move, which in turn drives the rotating block 63 to rotate. The rotation of the rotating block 63 adjusts the angle of the two auxiliary lamps 61. When the angle between the auxiliary lamp 61 and the curing lamp 52 is adjusted to 30°, the curing lamp 52 focuses the light. The auxiliary lamp 61 reflects the scattered light from the edge of the curing lamp 52 back to the center, reducing the diffusion of light in all directions and improving the curing efficiency for thick-walled materials. Then, when the angle between the auxiliary lamp 61 and the curing lamp 52 is adjusted to 60°, the curing lamp 52 diffuses the light. The constraint of the auxiliary lamp 61 on the light from the edge of the curing lamp 52 is weakened, and more light can diffuse in all directions, ultimately achieving adjustment of the intensity and range of the curing lamp 52.

[0037] like Figure 3 , Figure 4 As shown, the extrusion assembly 4 includes an extrusion head 41, a frame 42, and a cover 43. The frame 42 is located on the upper surface of the base plate 11 and is fixedly connected to the base plate 11. A drive unit 44 is provided at the top of the frame 42. The drive unit 44 is used to control the movement of the extrusion head 41. The fixed end of the drive unit 44 is fixedly connected to the frame 42. A connector 45 is provided at the output end of the drive unit 44. The extrusion head 41 is provided at the bottom end of the connector 45. The cover 43 is fitted over the extrusion head 41, and the top of the cover 43 is rotatably connected to the connector 45.

[0038] Specifically, the frame 42 is located on the upper surface of the base plate 11, and the bottom end of the frame 42 is fixedly connected to the upper surface of the base plate 11. The frame 42 is used to support the drive unit 44. The drive unit 44 is existing technology and is mainly used to control the movement of the extrusion head 41. Then, when the drive unit 44 works, it controls the movement of the connecting piece 45. The movement of the connecting piece 45 drives the extrusion head 41 to move. The bottom end of the extrusion head 41 is provided with an output end, which is mainly used to squeeze the material onto the worktable 34. The cover 43 serves as a second protective device to prevent the material from reacting violently and affecting other components.

[0039] like Figure 5 As shown, the detection component 7 includes a sleeve 71, a spring 72, and a scraper 73. The sleeve 71 is fitted onto the output end of the extruder head 41. The spring 72 is provided between the sleeve 71 and the extruder head 41. A blocking block 74 is provided at the bottom end of the sleeve 71 and is fixedly connected to the bottom end of the sleeve 71. The scraper 73 is located on the outer wall of the sleeve 71 and is fixedly connected to the sleeve 71.

[0040] Specifically, when the extruder 41 is working, the material is discharged through the output end. Since the material is in a semi-solid state, the movement of the material will squeeze the blocking block 74 at the bottom of the sleeve 71. The movement of the blocking block 74 will drive the sleeve 71 to move. The movement of the sleeve 71 will stretch the spring 72. The two ends of the spring 72 are electrically connected to the external power supply. When the spring 72 is stretched, the overall length increases and the cross-sectional area decreases, resulting in an increase in resistance. The higher the resistance value, the greater the squeezing pressure on the material. Then, when the curing lamp 52 is in a diffused light state, because the curing lamp 52 has a large irradiation range, it is easy to cover the output end of the extruder 41, causing the material to harden. However, due to the protection of the sleeve 71, the material is prevented from hardening. Finally, after the extruder 41 finishes working, the sleeve 71 is pulled by the spring 72 and moves towards the extruder 41. Then, the inner wall of the sleeve 71 will come into contact with the scraper 73, and the residue will be scraped off without affecting subsequent use.

[0041] like Figure 1 , Figure 9 As shown, the housing assembly 2 includes an outer shell 21 and an observation window 22. The bottom end of the outer shell 21 is fixedly connected to the base plate 11. The outer shell 21 has a groove, and the observation window 22 cooperates with the groove.

[0042] Specifically, the bottom of the outer shell 21 is fixedly connected to the upper surface of the base plate 11. The outer shell 21 is used to protect external operators. The outer shell 21 has a groove for observing the materials on the table. The observation window 22 is a transparent plate.

[0043] Working principle: During device operation, energetic material is discharged through extruder 41. As the material is discharged, its movement compresses the baffle block 74 at the bottom of sleeve 71. The movement of baffle block 74 causes sleeve 71 to move, which in turn stretches spring 72, increasing its overall length, decreasing its cross-sectional area, and increasing its resistance. The extrusion pressure is determined based on the resistance value. The material is then extruded onto worktable 34 and irradiated by light-curing lamp 52. At this point, by adjusting the angle of auxiliary lamp 61, when the angle between auxiliary lamp 61 and light-curing lamp 52 reaches 30°, auxiliary lamp 61 reflects the scattered light from the edge of light-curing lamp 52 back to the center, reducing light diffusion and improving the light-curing efficiency for thick-walled materials. This concentrates the light from light-curing lamp 52. When the angle between the two lights is adjusted to 60°, the constraint of the auxiliary light 61 on the edge light of the curing lamp 52 is reduced, and more light can diffuse in all directions, achieving diffused light from the curing lamp 52. During this process, because the curing lamp 52 has a large irradiation range, it can easily cover the output end of the extruder head 41, causing the material to harden. However, due to the protection of the sleeve 71, the material hardening is prevented. Finally, when the curing ends, the resistance wire 35 generates a small amount of heat when energized. Since the resistance wire 35 is located at the bottom of the table panel 36, the shape memory alloy surface at the bottom of the table panel 36 is the first to come into contact with the resistance wire 35 and bends due to heat. Ultimately, the table panel 36 bends slightly as a whole. Because the surface of the table panel 36 is made of silicone, it has a heat insulation effect, greatly reducing the impact of heat on the bottom of the molded material, making it convenient for workers to pick up the molded material without the need for additional tools.
