[0002] Customized insoles are professionally designed and made based on personalized factors such as the user's foot shape, arch height, and gait characteristics. During the production process of customized insoles, plantar scanning technology is used to obtain three-dimensional data of the user's soles. Based on the collected data, an insole model that best suits the user's foot shape is designed, and then the insole model is integrated with a 3D printer and materials for printing.

[0003] The patent with announcement number CN113524681B discloses a rapid prototyping device for customized insoles, including a 3D printer body, and also including: a plurality of insole plates vertically stacked in a stacking rack assembly; a conveying mechanism arranged at the center of the frame; the stacking rack assembly and the 3D printer body are symmetrically installed on the top of the frame along the conveying direction of the conveying mechanism, and the conveying mechanism is equipped to transport the insole plates falling one by one in the stacking rack assembly to the bottom of the printer head of the stacking rack assembly to be detached. The rapid prototyping device for customized insoles provided by the invention is improved by utilizing the transmission principle of the conveying mechanism, and the cooperation among the push plate assembly I, push plate assembly II and the switching assembly added to the conveying mechanism is utilized to realize the purpose of automatic plate filling and plate removal, so that the entire production link greatly reduces the participation of manual labor, so that the technology can be applied to assembly line production, improves the overall production efficiency, and reduces the corresponding labor cost.

[0004] However, the above technical solution still has the following deficiencies in practical application: Since the materials used for 3D printed insoles usually have high adhesion, which helps to ensure the stability and accuracy of the insoles during the printing process, the insoles will adhere to the printing platform after being formed, and need to be manually peeled off from the printing platform using a spatula or scraper, which is more labor-intensive, especially when dealing with a large number of insoles.

[0016] The beneficial effects of the present invention are as follows: 1.

The rapid prototyping device for customized insoles described in the present invention utilizes an insole size-adaptive placement mechanism and an alternating peeling auxiliary mechanism to enable multiple molded insoles to be removed from a printing platform and stacked on a storage plate in sequence, thereby eliminating the need for manually removing the molded insoles and saving effort. In addition, according to the size of the insole, the push plates 1 and 2 can be driven to form barriers on the front and rear sides and the left and right sides of the insole, thereby limiting the insole and preventing the insole placed on the storage plate from collapsing due to external forces and other factors.

Then, the push plates 1 and 2 can be driven away from the insoles, so that the insoles can be stacked and fall into the collection container. In addition, when the scraper strips the insole from the printing platform, the pressure blocks on both sides press the insole alternately, which can ensure that the scraper strips the insole from the printing platform smoothly, and the insole will not bounce up due to the sudden peeling of the position where the insole is most firmly attached to the printing platform, causing the insole to curl or shift, thereby ensuring the normal transfer of the insole, and when the scraper strip returns to the bottom of the insole and lifts it up, the insole can be pressed down by the pressure blocks on one side first, and when the scraper strip is at the bottom of the insole, the pressure blocks are driven to loosen the insole, thereby avoiding the situation where the scraper strip pushes the insole to move instead of moving it under it when the scraper strip contacts the insole again, so that a gap can be smoothly generated between the insole and the printing platform, further ensuring the normal transfer of the insole.

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In this embodiment, Figure 7 As shown, threaded rods 4 34 are rotatably provided at both ends of the slot plate 3 35 , and the threaded rods 4 34 are threadedly connected to one side of the bottom of the scraper strip 33 , and a motor 7 36 is fixedly connected to one end of the slot plate 3 35 , and the output end of the motor 7 36 is fixedly connected to one end of the threaded rod 4 34 .

[0024] Specifically, in the prior art, the material used for 3D printed insoles usually has high adhesion, which helps to ensure the stability and accuracy of the insoles during the printing process. Therefore, after the insoles are formed, they will adhere to the printing platform 3, and it is necessary to manually use a spatula or a scraper to peel the insoles from the printing platform 3, which is relatively labor-intensive. In particular, when a large number of insoles are processed, the efficiency will be significantly affected. In addition, manual peeling may cause damage to the insoles due to improper operation or lack of experience, affecting the quality of the final product. Therefore, in order to solve the above problems, when the present embodiment is used, under the action of the guide rail mechanism 2, the orientation of the print head 40 and the printing platform 3 can be adjusted, and the print head 40 is used for 3D printing, so that the insole is gradually formed on the printing platform 3. This printing process is a prior art and will not be described in detail here. After the insole is formed, the motor seven 36 drives the threaded rod four 34 to rotate, so that the scraper bar 33 moves in the slide groove of the groove plate three 35, and because the upper side of the scraper bar 33 is in contact with the upper surface of the printing platform 3, when the scraper bar 33 passes the bottom of the insole, the insole is gradually peeled off from the printing platform 3 until the scraper bar 33 moves from one side of the insole to the other side, thereby realizing the automatic separation of the formed insole from the printing platform 3, eliminating the process of manually peeling the insole from the printing platform 3 with a spatula or a scraper, saving manpower, and at the same time, avoiding the situation where the insole is damaged due to improper operation or lack of experience when manually peeling the insole, thereby affecting the quality of the final product.

[0030] The 3D printer body 1 is also provided with an insole size-adaptive placement mechanism for placing the molded insole; The insole size adaptive placement mechanism includes a placement plate 21 rotatably arranged on one side of the upper end of the 3D printer body 1, a slide bar 3 24 is fixedly connected to one side of the placement plate 21, a slot plate 1 25 is slidably connected to the slide bar 3 24, a slot plate 26 is fixedly connected to one side of the slot plate 1 25, push plates 1 28 are slidably connected to both sides of the slot of the slot plate 1 25, push plates 2 31 are slidably connected to both sides of the slot of the slot plate 26, and push plates 1 28 and 31 can both pass through the through holes on the placement plate 21 and can move at the through holes.

[0031] A motor 5 22 is fixedly connected to one side of the upper end of the 3D printer body 1, and the output end of the motor 5 22 is fixedly connected to one end of the placement plate 21. A threaded rod 3 32 is threadedly connected to one end of the slot plate 1 25, and the upper end of the threaded rod 3 32 is rotatably set on the placement plate 21. A motor 8 23 is fixedly connected to one side of the upper end surface of the placement plate 21, and the output end of the motor 8 23 is fixedly connected to one end of the threaded rod 3 32.

[0032] Two ends of the slot plate 25 are rotatably provided with two-way threaded rods 27, the lower end of the push plate 28 is threadedly connected to the two-way threaded rod 27, one end of the slot plate 25 is fixedly connected to a motor 9 42, and the output end of the motor 9 42 is fixedly connected to one end of the two-way threaded rod 27, two ends of the slot plate 26 are rotatably provided with two-way threaded rods 30, both sides of the two-way threaded rods 30 are threadedly connected to the lower end of the push plate 2 31, one end of the slot plate 26 is fixedly connected to a motor 6 29, and the output end of the motor 6 29 is fixedly connected to one end of the two-way threaded rod 30.

[0033] Specifically, in the above embodiment, although the scraper 33 can be used to peel the insole from the printing platform 3, the peeled insole still needs to be manually removed from the printing platform 3 before the subsequent printing work can be carried out, which is labor-intensive. In addition, in some cases, the same customer will customize multiple insoles of the same size to ensure that each pair of shoes has a suitable insole. Therefore, multiple insoles need to be printed one by one. When the peeled insole is pushed into a collection container for collection, the insole will be messy in the collection container, which is not conducive to the subsequent storage and further processing of the insole. Therefore, in order to avoid this problem, the present embodiment is used for the same batch of insoles of the same size; when the insoles are peeled off from the printing platform 3, the motor 2 12 is used to drive the threaded rod 2 13 to rotate according to the length of the insoles, and the spacing between the front and rear sliders 10 can be adjusted so that the pressure blocks 18 on the front and rear sides are located at both ends of the insoles, and when the spacing between the front and rear sliders 10 is adjusted, the telescopic rod 15 will also be telescoped, and then according to the width of the insoles, the motor 3 17 is used to drive the bidirectional threaded rod 1 16 to rotate so that the sliders 10 on both sides slide in different directions at the same time until the pressure blocks 18 are aligned with the edges of the insoles, and then the telescopic rod 15 is driven to rotate. The scraper strip 33 is moved to the middle position below the insole, and the electric push rod 4 38 is used to drive the groove plate 3 35 and the scraper strip 33 to rise, and the insole is lifted up. When the insole contacts the pressing block 18, the motors 4 20 on both sides are started to drive the fastening rod 19 to rotate, so that the end of the fastening rod 19 fits with the bottom of the insole. The insole can be clamped under the cooperation of the pressing block 18 and the fastening rod 19, and then the motor 6 drives the threaded rod 5 to rotate, so that the frame 9 is moved away from the top of the printing platform 3 until the insole is above the placement plate 21, and then the electric push rod 7 drives the insole to descend until the insole is close to the placement plate 21, and then the fastening rod 19 is driven to rotate. The fixing rod 19 is away from the insole, and the insole is placed on the storage plate 21. Then, the above operation is repeated to stack multiple shaped insoles on the storage plate 21 in sequence, thereby eliminating the need to manually remove the shaped insoles, which is more labor-saving. In addition, the distance between the two push plates 1 28 and the two push plates 2 31 can be adjusted according to the size of the insole by driving the two-way threaded rod 3 30 to rotate through the motor 6 29 and driving the two-way threaded rod 2 27 to rotate through the motor 9 42. Moreover, whenever an insole is placed on the storage plate 21, the motor 8 23 will drive the threaded rod 3 32 to rotate, and make the groove plate 1 25 and the groove plate 2 26 rise at the same time, so that The push plate 1 28 and the push plate 2 31 form a barrier on the front and back sides and the left and right sides of the insole, so as to limit the insole and prevent the insole placed on the storage board 21 from collapsing due to external forces and other factors. When all the insoles are placed on the storage board 21, the push plate 1 28 and the push plate 2 31 can be used again to clamp the insole, and then the motor 5 22 drives the storage board 21 to flip 180 degrees, and the collection container is placed under the storage board 21. Then, the push plate 1 28 and the push plate 2 31 are driven away from the insole, so that the insole can fall into the collection container in a stacked manner, which is convenient for the subsequent storage and further processing of the insole. Although the above method can realize the neat placement of multiple molded insoles, during the insole printing and molding process, some parts of the bottom of the insole may not be fully in contact with the printing platform 3 due to uneven material flow, resulting in the insole only partially firmly adhering to the printing platform 3. This is a common situation in the 3D printing process. When the scraper 33 contacts the insole, the insole will be pushed by the scraper 33. Therefore, when the position where the insole is most firmly adhered to the printing platform 3 is peeled off by the scraper 33, the insole will bounce up due to the sudden loss of adhesion, resulting in curling or offset of the insole. , resulting in the insole being unable to be smoothly transferred to the storage plate 21, and before the scraper 33 lifts the insole, because the insole and the printing platform 3 have been peeled off, when the scraper 33 contacts the insole again, it may push the insole to move instead of moving it underneath, resulting in no gap between the insole and the printing platform 3, and still causing the inability to transfer. Therefore, in order to avoid the above problems, before the scraper 33 peels the insole from the printing platform 3, multiple pressing blocks 18 can be driven to align with the four corners of the insole, and when the scraper 33 starts to contact one side of the insole, the electric push rod 11 is used to drive it away The two pressing blocks 18 on one side of the scraper 33 descend and press one side of the insole, and the scraper 33 can start to peel the insole. When the scraper 33 approaches the pressing block 18 pressing the insole, the two pressing blocks 18 on the other side will descend again under the action of the electric push rod 11 to press the insole tightly, and the pressing block 18 close to the scraper 33 will loosen the insole without affecting the passage of the scraper 33 until the scraper 33 passes the bottom of the insole. During the whole peeling process, the pressing blocks 18 on both sides alternately press the insole, which can ensure that the scraper 33 can smoothly peel the insole from the printing platform 3, and will not be caused by the insole and the printing platform 3. The position where the adhesion is most firmly maintained is suddenly peeled off, causing the insole to bounce up, resulting in curling or displacement of the insole, thereby ensuring the normal transfer of the insole. In addition, when the scraper strip 33 returns to the bottom of the insole and lifts it up, the insole can be pressed down by the pressure block 18 on one side. When the scraper strip 33 is at the bottom of the insole, the pressure block 18 is driven to loosen the insole, thereby avoiding the situation where the scraper strip 33 pushes the insole to move instead of moving it underneath when the scraper strip 33 contacts the insole again, so that a gap can be smoothly created between the insole and the printing platform 3, further ensuring the normal transfer of the insole.

[0034] Working principle: Under the action of the guide mechanism 2, the orientation of the print head 40 and the printing platform 3 can be adjusted, and the print head 40 is used for 3D printing, so that the insole is gradually formed on the printing platform 3. When the insole is formed, the motor 7 36 drives the threaded rod 4 34 to rotate, so that the scraper 33 moves in the slide groove of the groove plate 3 35. In addition, since the upper side of the scraper 33 is in contact with the upper surface of the printing platform 3, when the scraper 33 passes the bottom of the insole, the insole will be gradually peeled off from the printing platform 3 until the scraper 33 moves from one side of the insole to the other side, thereby realizing the automatic separation of the formed insole from the printing platform 3, eliminating the process of manually peeling the insole from the printing platform 3 using a spatula or a scraper, saving manpower, and at the same time, avoiding manual When peeling the insole, the insole is damaged due to improper operation or lack of experience, which affects the quality of the final product. After the insole is peeled off from the printing platform 3, the motor 2 12 is used to drive the threaded rod 2 13 to rotate according to the length of the insole, and the spacing between the front and rear sliders 10 can be adjusted so that the pressure blocks 18 on the front and rear sides are at both ends of the insole. Moreover, when the spacing between the front and rear sliders 10 is adjusted, the telescopic rod 15 will also be telescoped. Then, according to the width of the insole, the motor 3 17 is used to drive the bidirectional threaded rod 1 16 to rotate so that the sliders 10 on both sides slide in different directions at the same time until the pressure block 18 is aligned with the edge of the insole. Then, the scraper 33 is driven to move to the middle position below the insole, and the electric push rod 4 38 is used to drive the slot plate 3 35 and the scraper 33 to rise, and the insole is moved upward. When the insole contacts the pressing block 18, the motors 20 on both sides are started to drive the fastening rods 19 to rotate, so that the ends of the fastening rods 19 fit with the bottom of the insole, and the insole can be clamped under the cooperation of the pressing block 18 and the fastening rods 19. Then, the motor 6 drives the threaded rod 5 to rotate, so that the frame 9 is moved away from the top of the printing platform 3 until the insole is above the placement board 21, and then the electric push rod 7 drives the insole to descend until the insole is close to the placement board 21, and then the fastening rods 19 are driven away from the insole, and the insole is placed on the placement board 21. Then, the above operation is repeated, so that multiple molded insoles can be stacked on the placement board 21 in sequence, thereby eliminating the process of manually removing the molded insoles, which is more labor-saving, and can be adjusted according to the size of the insole. The motor 6 29 drives the two-way threaded rod 3 30 to rotate, and the motor 9 42 drives the two-way threaded rod 27 to rotate, so as to adjust the distance between the two push plates 1 28 and the two push plates 2 31. Moreover, whenever an insole is placed on the storage board 21, the motor 8 23 drives the threaded rod 3 32 to rotate, and makes the groove plate 1 25 and the groove plate 2 26 rise at the same time, so that the push plates 1 28 and the push plates 2 31 form a barrier on the front and back sides and the left and right sides of the insole, thereby limiting the insole and preventing the insole placed on the storage board 21 from collapsing due to external forces and other factors. When all the insoles are placed on the storage board 21, the push plates 1 28 and the push plates 2 31 can be used again to clamp the insoles, and then the storage board 21 can be turned 180 degrees by the motor 5 22.By placing the collection container under the storage plate 21 and driving the push plate 1 28 and the push plate 2 31 away from the insole, the insole can be stacked and dropped into the collection container, which is convenient for the subsequent storage and further processing of the insole. Although the above method can realize the neat placement of multiple molded insoles, during the insole printing and molding process, some parts of the bottom of the insole may not be fully in contact with the printing platform 3 due to uneven material flow, resulting in the insole only partially firmly adhering to the printing platform 3. This is a common situation in the 3D printing process. When the scraper 33 contacts the insole, the insole will be pushed by the scraper 33. Therefore, When the position where the insole is most firmly adhered to the printing platform 3 is peeled off by the scraper 33, the insole will bounce up due to the sudden loss of adhesion, resulting in curling or deviation of the insole, which makes it impossible to smoothly transfer the insole to the storage plate 21. In addition, before the scraper 33 lifts the insole, because the insole and the printing platform 3 have been peeled off, when the scraper 33 contacts the insole again, it may push the insole to move instead of moving it under it, resulting in no gap between the insole and the printing platform 3, and still causing the inability to transfer. Therefore, in order to avoid the above problems, multiple pressing blocks can be driven before the scraper 33 peels the insole from the printing platform 3. 18 is aimed at the four corners of the insole. When the scraper 33 begins to contact one side of the insole, the electric push rod 11 is used to drive the two pressing blocks 18 away from the scraper 33 to descend and press one side of the insole. The scraper 33 can then start to peel the insole. When the scraper 33 approaches the pressing block 18 pressing the insole, the two pressing blocks 18 on the other side will descend under the action of the electric push rod 11 to press the insole tightly, and the pressing block 18 close to the scraper 33 will loosen the insole without affecting the passage of the scraper 33 until the scraper 33 passes through the bottom of the insole. During the entire peeling process, the pressing blocks 18 on both sides alternately press the insole, which can ensure that the scraper 33 can smoothly remove the insole from the printing The insole will not be peeled off from the platform 3, and the insole will not bounce up due to the sudden peeling of the position where the insole is most firmly attached to the printing platform 3, causing the insole to curl or deviate, thereby ensuring the normal transfer of the insole. Moreover, when the scraper 33 returns to the bottom of the insole and lifts it up, the insole can be pressed down by the pressing block 18 on one side. When the scraper 33 is at the bottom of the insole, the pressing block 18 is driven to loosen the insole, thereby avoiding the situation that when the scraper 33 contacts the insole again, the scraper 33 pushes the insole to move instead of moving it under it, so that a gap can be smoothly generated between the insole and the printing platform 3, further ensuring the normal transfer of the insole.
