When the driving mechanism on the corresponding device body is started, the turntable 3 of the turntable assembly is driven to rotate through the transmission matching structure.

[0055] The turntable assembly provided by the embodiment can be applied to a curing box or any other device main body which needs to install a turntable 3 and drive the turntable 3 to rotate. In use, the turntable assembly is placed so that the transmission matching structure arranged on the turntable assembly is in transmission matching with the driving mechanism of the device main body. In this way, the turntable 3 can be taken out of the device main body to place and take out objects (products / 3D printed parts), the operation process is simple and convenient, and the accurate positioning of the objects (products / 3D printed parts) on the turntable 3 can be ensured, so that the mispositioning of the objects (products / 3D printed parts) on the turntable 3 when being placed does not affect the processing effect of the objects (products / 3D printed parts), for example, the adjacent objects (products / 3D printed parts) are prevented from being too close or partially overlapped to cause mutual shielding and thus reduce the photocuring effect of the objects (products / 3D printed parts), so that a better processing effect of the objects (products / 3D printed parts) can be ensured.

[0056] In the optional embodiment of the turntable assembly provided by the embodiment, the above-mentioned turntable 3 is installed on the support 4 through the transmission shaft 5. Specifically, the transmission shaft 5 is rotatably installed on the support 4, the turntable 3 is fixedly connected with the transmission shaft 5, and the transmission matching structure is fixedly connected with the transmission shaft 5. The more specific installation mode can refer to Figure 1 , and the shaft sleeve 52, the auxiliary bearing 53, the ball bearing seat 54 and the fixed seat 55 are additionally arranged. In installation, the transmission shaft 5 is rotatably installed on the support 4 along the vertical direction, the auxiliary bearing 53 is installed in the shaft sleeve 52 or on the support 4, so that the auxiliary bearing 53 is aligned with the shaft sleeve 52; the transmission shaft 5 passes through the auxiliary bearing 53 and the shaft sleeve 52, and the upper and lower ends of the transmission shaft 5 extend by a proper length; the ball bearing seat 54 and the fixed seat 55 are installed on the lower part of the transmission shaft 5, the transmission shaft 5 is fixed with the fixed seat 55, and the fixed seat 55 is connected to the support 4 through the ball bearing seat 54; the turntable 3 is fixed to the upper end of the transmission shaft 5; and the transmission matching structure is fixed to the lower end of the transmission shaft 5. The above-mentioned installation mode of the transmission shaft 5 combines the shaft sleeve 52, the auxiliary bearing 53, the ball bearing seat 54 and the fixed seat 55 to form a multi-level support and resistance reduction system, so as to ensure the smooth rotation of the transmission shaft 5 and improve the rotation performance of the turntable 3.

[0057] In the optional embodiment of the turntable assembly provided in the present embodiment, in order to improve the operation convenience of the user to place the turntable assembly in the designated position of the device main body or to take out the turntable assembly from the designated position of the device main body, and improve the user experience, a guide assembly that is movably connected with the device main body is further arranged on the bracket 4, and the guide assembly is used to guide the turntable assembly to be placed in the designated position of the device main body or to guide the turntable assembly placed in the designated position of the device main body to be separated from the device main body. The guide assembly can but not limited to include a roller that is rotatably connected with the bracket 4, and the roller is guided with the guide rail 2 arranged on the device main body, so that the bracket 4 can be pushed or pulled along the guide rail 2 on the device main body to quickly push in or take out the turntable assembly. It should be noted that the roller structure is only one optional design structure form of the guide assembly, and in the present embodiment, when the guide assembly is arranged, the guide assembly can also be a slider structure that can be guided with the guide rail 2 arranged on the device main body. However, compared with the slider structure, the friction between the bracket 4 and the guide rail 2 is rolling friction when the roller is used for guiding, and the friction is smaller, which is more conducive to quickly and smoothly placing or taking out the turntable 3 in the designated position of the device main body, improving the operation efficiency, reducing the resistance, making the user feel more convenient during the pushing and pulling process, improving the user experience, and reducing the wear between the guide rail 2 and the bracket 4, improving the durability of the overall structure.

[0058] In addition, in the optional embodiment of the turntable assembly provided in the present embodiment, a limiting structure is arranged on the bracket 4 of the turntable assembly, and the limiting structure is limitedly connected with the device main body when the turntable assembly is placed in the designated position of the device main body. There are various optional structure types for the limiting structure, for example but not limited to, the limiting structure includes a spring pin 43 or other limiting piece movably mounted on the bracket 4, and when the turntable assembly is placed in the designated position of the device main body, the limiting piece is inserted into a locking hole of the device main body to realize the limiting connection between the limiting structure and the device main body, so as to prevent the turntable 3 from being displaced due to vibration or other external force during the operation of the device after the turntable assembly is placed in the designated position of the device main body, and affect the processing effect on the objects (products / 3D printed parts) on the turntable 3, thereby improving the working stability of the turntable assembly after the turntable assembly is placed in the designated position of the device main body.

[0059] In addition, when the device main body is provided with the guide rail 2, a limiting protrusion 44 can be fixedly connected or integrally connected to the bottom surface of the bracket 4, and when the bracket 4 moves along the guide rail 2, the limiting protrusion 44 is blocked at the rear side of the limiting bracket 11 arranged on the device main body, so as to prevent the bracket 4 from slipping off the guide rail 2.

[0060] Furthermore, in an optional embodiment of the turntable assembly provided in this example, the turntable 3 includes a turntable retaining ring 33, a glass plate 32, and a turntable pad 31. The glass plate 32 is disposed inside the turntable retaining ring 33 and fixedly connected to it. The turntable pad 31 is disposed inside the turntable retaining ring 33 in the space above the glass plate 32. Glass (especially ultra-clear glass) has higher transmittance to ultraviolet light and better heat resistance than PMMA (polymethyl methacrylate). When the main body of the equipment used in the turntable assembly provided in this example is a curing chamber, the use of a glass plate to modify the structure of the turntable 3 can improve the curing effect. The turntable pad 31 is disposed above the glass plate 32, which facilitates the replacement of the turntable pad 31 when the light transmittance of the turntable pad 31 decreases due to material residue after multiple curing cycles. It is worth noting that in this optional embodiment, the turntable pad 31 can be made of transparent or opaque materials. This example does not limit its transparency (light transmittance), as long as it can transmit light, it is acceptable. Higher transparency (light transmittance) and better heat resistance are the best material selection. The specific fixing method for "the glass plate 32 is disposed inside the turntable retaining ring 33 and fixedly connected to the turntable retaining ring 33" includes, but is not limited to, a fixing method in which a groove is provided on the inner wall of the turntable retaining ring 33, and the glass plate 32 is snapped into the groove, or as... Figure 1 As shown, the bottom of the turntable retaining ring 33 is provided with an annular protrusion extending inward therein. The glass plate 32 is placed inside the turntable retaining ring 33 and fixed to the upper surface of the annular protrusion by screws; or, other methods are used to place the glass plate 32 inside the turntable retaining ring 33 and fix it to the turntable retaining ring 33.

[0061] Second aspect

[0062] The second aspect of this embodiment provides a stage, which is installed inside a curing chamber or other device body that requires a turntable 3 to be installed and driven to rotate. It can be used in conjunction with the turntable assembly provided in the first aspect and any of its optional embodiments. Specifically, the stage includes a fixed base 1 and a drive mechanism installed on the fixed base 1. The drive mechanism engages with the transmission structure provided on the turntable assembly when the turntable assembly is placed at a designated position on the device body.

[0063] Furthermore, the platform also includes a guide rail 2 fixed relative to the fixed base 1. Pushing the bracket 4 backward along the guide rail 2 positions the turntable assembly at a designated location on the main body of the device, and pulling the bracket 4 forward along the guide rail 2 removes the turntable assembly from the main body. When the turntable assembly moves along the guide rail 2, the bracket 4 or rollers mounted on the bracket 4 contact the surface of the guide rail 2. The guide rail 2 can be fixedly connected to the fixed base 1 of the platform, or fixed to the inner wall of the main body of the device on which the platform is mounted, as long as it is fixed relative to the platform. To increase the smoothness of the push-pull motion of the turntable assembly along the guide rail 2, preferably, rollers are rotatably connected to the bracket 4 of the turntable assembly as a guide component. The specific installation method can be as follows: Figure 1 As shown, a roller bracket 411 is provided at the edge of the bracket 4, and a roller shaft 41 is fixed on the roller bracket 411. Rollers are rotatably mounted on the roller shaft 41. When the turntable assembly moves along the guide rail 2, each roller provided on the bracket 4 contacts the rail surface of the guide rail 2.

[0064] Alternatively, to further enhance the smoothness of the turntable assembly's movement along the guide rail 2, a roller is provided on the front side of the guide rail 2. Figure 4 As shown in the figure, when the turntable assembly moves along the guide rail 2, the bracket 4 contacts the roller (roller 25) located on the front side of the guide rail 2.

[0065] Alternatively, the guide rail 2 may include a left guide rail and a right guide rail.

[0066] Specifically: Each guide rail 2 has a front stop for limiting the support 4 or the rollers on the support 4. The front stop can be the aforementioned roller 25, or a front guard 23 connected to the front of each guide rail 2, which to a certain extent prevents the support 4 from slipping off the guide rail 2 when it is pulled out. Optionally, the left and right guide rails each have a side stop for limiting the corresponding side area of ​​the turntable assembly or the rollers on the corresponding side area on their respective length directions. The side stop can be a side guard 24 connected to the right side of the left guide rail and the left side of the right guide rail, or when the guide rail 2 is installed on the inner wall of the equipment body, the inner wall of the equipment body can be used as the side stop.

[0067] When the rollers are rotatably installed on the support 4 of the turntable assembly, optionally, the left and right guide rails each include an upper guide rail 21 and a lower guide rail 22, and when the turntable assembly moves along the guide rail 2, the corresponding side edge region of the support 4 or at least one roller arranged at the corresponding side edge region of the support 4 is limited between the upper guide rail 21 and the lower guide rail 22. For example, but not limited to, the support 4 of the turntable assembly is provided with an upper roller 421 matched with the upper guide rail 21 and a lower roller 422 matched with the lower guide rail 22, and when the turntable assembly moves along the guide rail 2, the lower roller 422 is supported on the rail surface of the lower guide rail 22. That is, when the turntable assembly moves along the guide rail 2, the upper roller 421 and the lower roller 422 are limited between the upper guide rail 21 and the lower guide rail 22. By arranging the upper guide rail 21, the height of the support 4 when the turntable assembly is placed or separated from the specified position of the device main body is limited, the stability of the turntable 3 when moving is increased, and the objects on the turntable 3 are prevented from being overturned.

[0068] In addition, optionally, a limiting support 11 is arranged on the front side of the fixed seat 1 of the object table, and the limiting support 11 is matched with the limiting structure arranged on the turntable assembly when the turntable assembly is placed at the specified position of the device main body. The limiting structure arranged on the turntable assembly includes a limiting piece movably installed on the support 4, and the top of the limiting support 11 is provided with a downwardly extending locking hole, and the limiting piece is inserted into the locking hole to lock the turntable assembly when the turntable assembly is placed at the specified position of the device main body. In an optional embodiment, the limiting piece is a spring pin 43, and the spring pin 43 is automatically locked when the turntable 3 is placed at the specified position, preventing the turntable 3 from being displaced. In addition, optionally, the limiting convex portion 44 can be fixedly connected or integrally connected to the bottom surface of the support 4, and the limiting convex portion 44 is blocked at the rear side of the limiting support 11 when the support 4 moves along the guide rail 2, so as to prevent the turntable assembly from slipping off the guide rail 2.

[0069] Further, an extension guide portion 111 can be arranged on the front side of the limiting support 11, the upper surface of the extension guide portion 111 is a guide inclined surface with gradually increasing height from front to rear, the design of the extension guide portion 111 can guide the turntable assembly to be smoothly pushed in, avoid the design of the limiting support 11 causing the process of sliding the turntable assembly along the guide rail 2 to be stuck, and the limiting piece can be guided to slide along the guide inclined surface to the top surface of the limiting support 11 and enter the locking hole, so as to realize the quick locking of the support 4 of the turntable assembly when the turntable assembly is pushed in, further improve the positioning efficiency and positioning accuracy.

[0070] The specific structure of the driving mechanism of the object table is as follows. In the optional embodiment of the present embodiment, the driving mechanism comprises a driving part, a main shaft 6, a driving gear 61, a driven shaft 7 and a driven gear 71. Specifically, the main shaft 6 is rotatably installed on the fixed base 1 and is in transmission connection with the driving part. The driving gear 61 is sleeved and fixed on the main shaft 6, and an open retainer 62 is assembled at the position of the main shaft 6 above the driving gear 61 to limit the driving gear 61. The driven gear 71 is in meshing connection with the driving gear 61. The driven shaft 7 is rotatably installed on the fixed base 1, and the driven gear 71 is fixed on the driven shaft 7. Alternatively, the driven shaft 7 is fixedly installed on the fixed base 1, and the driven gear 71 is rotatably installed on the driven shaft 7. The transmission matching structure of the turntable assembly comprises a transmission shaft 5 fixedly connected to the turntable 3 and a transmission gear 51 fixed to the transmission shaft 5. When the turntable assembly (the support 4) is pushed or pulled along the guide rail 2, the transmission gear 51 can be in meshing connection or disconnection with the driven gear 71. During the process of pushing or pulling the turntable assembly (the support 4) along the guide rail 2, the transmission gear 51 can be automatically meshed or disconnected with the driven gear 71 without additional operation, which simplifies the use process and makes the use more convenient.

[0071] In the above structure, the driving gear 61, the driven gear 71 and the transmission gear 51 can be selected as straight gears or bevel gears. The driven gear 71 is used as an intermediate gear to change the extension directions of the wheel shafts corresponding to the gears other than the transmission gear 51, reasonably utilize the internal space of the equipment body, and adjust the gear parameters according to actual needs to adapt to different application occasions.

[0072] Since the torque is transmitted between the gears between the object table and the turntable assembly, the positioning accuracy between the turntable 3 and the transmission gear 51 can be ensured, and the running stability and reliability during the rotation of the turntable can be ensured.

[0073] In the structure, in order to further optimize the space layout, make the entire driving mechanism more compact, reduce the deviation on the power transmission path, and improve the smoothness and precision of transmission, in the optional embodiment, the main shaft 6 and the driven shaft 7 are designed to extend in the vertical direction. In the meshing state of the transmission gear 51 and the driven gear 71, the main shaft 6 corresponds to the transmission shaft 5 in an up-down manner. Further optionally, the driving gear 61 is meshed with the lower half of the driven gear 71. In the meshing state, the transmission gear 51 is meshed with the upper half of the driven gear 71. The up-down distance between the driving gear 61 and the transmission gear 51 is further reduced, and the structural compactness of the object table is further improved to release more internal space of the equipment body.
