Specifically, referring to Figures 1 to 4 The turntable assembly includes a bracket 4, a turntable 3 installed on the bracket 4, and a transmission matching structure fixedly connected to the turntable 3. When the turntable assembly is placed at a specified position of the equipment body, the transmission matching structure is matched with the driving mechanism on the corresponding equipment body. When the driving mechanism on the corresponding equipment body is started, the turntable 3 of the turntable assembly is driven to rotate through the above-mentioned transmission matching structure.

[0057] The turntable assembly provided in this embodiment can be applied to a curing box or any other equipment body that needs to install a turntable 3 and drive the turntable 3 to rotate. When in use, the turntable assembly is placed so that the transmission matching structure provided on the turntable assembly is matched with the driving mechanism of the equipment body. In this way, the turntable 3 can be taken out of the equipment body to take and put objects (products). The operation process is simple and convenient, and the precise positioning of the objects (products) on the turntable 3 can be ensured to avoid the misalignment of the objects (products) on the turntable 3 during placement, which affects the processing effect of the objects (products). For example, adjacent objects (products) are prevented from being too close or partially overlapped to cause mutual occlusion, thereby reducing the light curing effect of the objects (products), so as to ensure a better processing effect on the objects (products).

[0058] In an optional implementation of the turntable assembly provided in this embodiment, the turntable 3 is mounted on the bracket 4 via the transmission shaft 5. Specifically, the transmission shaft 5 is rotatably mounted on the bracket 4, the turntable 3 is fixedly connected to the transmission shaft 5, and the transmission matching structure is fixedly connected to the transmission shaft 5. A more specific installation method can be but is not limited to reference Figure 1 , a sleeve 52, an auxiliary bearing 53, a ball bearing 54 and a fixed bearing 55 are provided. During installation, the transmission shaft 5 is passed through the vertical direction and rotated to be installed on the bracket 4. The auxiliary bearing 53 is installed in the sleeve 52 or on the bracket 4 to ensure that the auxiliary bearing 53 is aligned with the sleeve 52; the transmission shaft 5 is passed through the auxiliary bearing 53 and the sleeve 52, and the upper and lower ends thereof are extended to an appropriate length; the ball bearing 54 and the fixed bearing 55 are installed at the lower part of the transmission shaft 5, the transmission shaft 5 is fixed to the fixed bearing 55, and the fixed bearing 55 is connected to the bracket 4 through the ball bearing 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 method of the transmission shaft 5 combines the sleeve 52, the auxiliary bearing 53, the ball bearing 54 and the fixed bearing 55 to form a multi-level support and drag reduction system to ensure that the transmission shaft 5 rotates steadily and smoothly, and improve the rotation performance of the turntable 3.

[0059] In the optional implementation of the turntable assembly provided in this embodiment, in order to improve the convenience of the user to place the turntable assembly at the designated position of the device body or to remove the turntable assembly from the designated position of the device body and to improve the user experience, a guide assembly that flexibly cooperates with the device body is further provided on the bracket 4, through which the turntable assembly is guided to be placed at the designated position of the device body or the turntable assembly placed at the designated position of the device body is guided to be separated from the device body. The guide assembly may include, but is not limited to, a roller rotatably connected to the bracket 4, and the roller cooperates with the guide rail 2 provided on the device body, so that the turntable assembly can be quickly pushed in or taken out by pushing and pulling the bracket 4 along the guide rail 2 on the device body. Among them, it should be noted that the roller structure is only an optional design structure of the guide component. In the present embodiment, when the guide component is set, the guide component can also be a slider structure that can cooperate with the guide rail 2 provided on the device body. However, in comparison, when the roller is used for guiding, the friction between the bracket 4 and the guide rail 2 on the device body is rolling friction, and the friction force is smaller, which is more conducive to the turntable 3 to be quickly and smoothly placed in or taken out of the designated position of the device body, improve the operating efficiency, and reduce the resistance, so that the user can feel a lighter operating feel during the pushing and pulling process, thereby improving the user experience, and can reduce the wear between the guide rail 2 and the bracket 4, thereby improving the durability of the overall structure.

[0060] In addition, in an optional implementation of the turntable assembly provided in the present embodiment, a limiting structure is provided on the bracket 4 of the turntable assembly, and the limiting structure cooperates with the equipment body when the turntable assembly is placed at a designated position of the equipment body. There are a variety of optional structural types for the limiting structure, such as but not limited to, the limiting structure includes a spring pin 43 or other limiting member movably mounted on the bracket 4, and when the turntable assembly is placed at a designated position of the equipment body, the limiting member is inserted into the lock hole of the equipment body to achieve the limiting cooperation between the limiting structure and the equipment body, so as to prevent the turntable 3 from shifting due to vibration or other external forces when the turntable assembly is placed at the designated position of the equipment body and the equipment is working, thereby affecting the processing effect of the object (product) on the turntable 3, and improving the working stability of the turntable assembly after the turntable assembly is placed at the designated position of the equipment body.

[0061] In addition, when the device body is provided with a guide rail 2, a limiting protrusion 44 can also be fixedly connected or integrally connected to the bottom surface of the bracket 4. When the bracket 4 moves along the guide rail 2, the limiting protrusion 44 is blocked on the rear side of the limiting bracket 11 provided on the device body to prevent the bracket 4 from slipping off the guide rail 2.

[0062] In addition, in the optional implementation of the turntable assembly provided in this embodiment, the turntable 3 includes a turntable retaining ring 33, a glass plate 32 and a turntable pad 31; the glass plate 32 is arranged inside the turntable retaining ring 33 and fixedly connected to the turntable retaining ring 33; the turntable pad 31 is arranged in the space above the glass plate 32 inside the turntable retaining ring 33. Glass (especially ultra-white glass) has a higher transmittance to ultraviolet rays and better heat resistance than PMMA (polymethyl methacrylate) material. When the main body of the equipment used in the turntable assembly provided in this embodiment is a curing box, the turntable 3 is improved by using a glass plate to improve the structure, which can improve the curing effect. The turntable pad 31 is arranged above the glass plate 32, so that the turntable pad 31 can be replaced when the transmittance of the turntable pad 31 decreases due to material residue after multiple curing. It is worth noting that in this optional implementation, the turntable pad 31 can be made of transparent or opaque materials. This embodiment does not limit its transparency (transmittance), as long as it can transmit light, and the best material is the one with higher transparency (transmittance) and better heat resistance. The specific fixing method of "the glass plate 32 is arranged 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 clamped inside the groove, or Figure 1 As shown, an annular convex edge extending inwardly is provided at the bottom of the turntable retaining ring 33, and the glass plate 32 is arranged inside the turntable retaining ring 33 and fixed to the upper surface of the annular convex edge by screws; or, the glass plate 32 is arranged inside the turntable retaining ring 33 and fixedly connected to the turntable retaining ring 33 by other means.

[0063] Second aspect

[0064] The second aspect of this embodiment provides a loading platform, which is installed inside a curing box or any other equipment body that needs to install a turntable 3 and drive the turntable 3 to rotate, and can be used in conjunction with the turntable assembly provided by the first aspect and any optional embodiment thereof. Specifically, the loading platform includes a fixed seat 1 and a driving mechanism installed on the fixed seat 1, and the driving mechanism cooperates with the transmission cooperation structure provided on the turntable assembly when the turntable assembly is placed at a specified position of the equipment body.

[0065] Furthermore, the stage also includes a guide rail 2 fixed in position relative to the fixed seat 1, and the turntable assembly is placed at a specified position of the device body by pushing the bracket 4 backward along the guide rail 2, and the turntable assembly placed at the specified position of the device body is removed from the device body by pulling the bracket 4 forward along the guide rail 2; when the turntable assembly moves along the guide rail 2, the bracket 4 or the roller provided on the bracket 4 contacts the rail surface of the guide rail 2. Among them, the specific installation position of the guide rail 2 can be fixedly connected to the fixed seat 1 of the stage, or fixed to the inner side wall of the device body on which the stage is installed, as long as it is fixed relative to the stage. In order to increase the push-pull smoothness of the turntable assembly when it moves along the guide rail 2, preferably, a roller is rotatably connected to the bracket 4 of the turntable assembly as a guide assembly, and 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, a roller shaft 41 is fixed on the roller bracket 411, and rollers are rotatably installed 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.

[0066] Further optionally, in order to further increase the smoothness of the movement of the turntable assembly along the guide rail 2, a roller ( Figure 4 As shown in the roller 25 , when the turntable assembly moves along the guide rail 2 , the bracket 4 contacts the roller (roller 25 ) disposed on the front side of the guide rail 2 .

[0067] In addition, optionally, the guide rail 2 includes a left guide rail and a right guide rail.

[0068] Among them: a front stopper is provided on the front side of each guide rail 2 for limiting the bracket 4 or the roller arranged on the bracket 4, and the front stopper can be the above-mentioned roller 25, or a front stopper 23 connected to the front side of each guide rail 2, to a certain extent, prevent the bracket 4 from slipping off the guide rail 2 when the bracket 4 is pulled out. Optionally, side stops for limiting the corresponding side edge area of ​​the turntable assembly or the roller arranged on the corresponding side edge area are respectively provided on the side areas in the length direction of the left guide rail and the right guide rail, and the side stops can be side stops 24 respectively 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 side wall of the equipment body, the inner side wall of the equipment body serves as the side stopper.

[0069] When the bracket 4 of the turntable assembly is rotatably mounted with rollers, optionally, the left guide rail and the right guide rail respectively include respective upper guide rails 21 and lower guide rails 22. When the turntable assembly moves along the guide rail 2, the corresponding side edge area of ​​the bracket 4 or at least one roller provided in the corresponding side edge area of ​​the bracket 4 is limited between the upper guide rail 21 and the lower guide rail 22. For example, but not limited to, the bracket 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. 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 lower roller 422 is limited between the upper guide rail 21 and the lower guide rail 22. By providing the upper guide rail 21, the height of the bracket 4 being lifted is limited when the turntable assembly is placed in or separated from the designated position of the device body, thereby increasing the stability of the turntable 3 during movement and avoiding overturning objects on the turntable 3.

[0070] In addition, optionally, a limiting bracket 11 is provided on the front side of the fixed seat 1 of the stage, and when the turntable assembly is placed at the designated position of the device body, the limiting bracket 11 cooperates with the limiting structure provided on the turntable assembly. The limiting structure provided on the turntable assembly includes a limiting member movably mounted on the bracket 4, and a locking hole extending downward is provided on the top of the limiting bracket 11. When the turntable assembly is placed at the designated position of the device body, the limiting member is inserted downward into the locking hole to lock the turntable assembly. Among them, in an optional embodiment, the limiting member adopts a spring pin 43, and the spring pin 43 of the lifting and unlocking type is used. When the turntable 3 is placed at the designated position, the spring pin 43 is automatically locked to prevent the turntable 3 from shifting. In addition, optionally, a limiting protrusion 44 can also 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 to prevent the turntable assembly from slipping off the guide rail 2.

[0071] Furthermore, an extension guide portion 111 can be provided on the front side of the limit bracket 11, and the upper surface of the extension guide portion 111 is a guide slope whose height gradually increases from front to back. The design of the extension guide portion 111 can guide the turntable assembly to be pushed in smoothly, thereby avoiding the design of the limit bracket 11 causing the turntable assembly to get stuck during the sliding process along the guide rail 2, and the above-mentioned limit member can be guided to slide smoothly along its guide slope to the top surface of the limit bracket 11 and enter the lock hole, so as to achieve rapid locking of the bracket 4 when the turntable assembly is pushed into place, thereby further improving the positioning efficiency and positioning accuracy.

[0072] As for the specific structural form of the driving mechanism provided on the stage, in an optional implementation of the present embodiment, the driving mechanism includes 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 mounted on the fixed seat 1 and is in transmission connection with the driving part, the driving gear 61 is fitted and fixed on the main shaft 6, and an open retaining ring 62 can be assembled at the part of the main shaft 6 located above the driving gear 61 to limit the driving gear 61. The driven gear 71 is meshed with the driving gear 61, wherein the driven shaft 7 is rotatably mounted on the fixed seat 1, and the driven gear 71 is fixed to the driven gear 71; or, the driven shaft 7 is fixedly mounted on the fixed seat 1, and the driven gear 71 is rotatably mounted on the driven shaft 7. The transmission matching structure of the turntable assembly includes 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 (bracket 4) is pushed or pulled along the guide rail 2, the transmission gear 51 can be engaged with or disengaged from the driven gear 71. During the process of pushing and pulling the turntable assembly (bracket 4) along the guide rail 2, the transmission gear 51 can automatically engage or disengage with the driven gear 71 without additional operation, thereby simplifying the use process and making it more convenient to use.

[0073] In the above structure, the driving gear 61, the driven gear 71 and the transmission gear 51 can be selected as spur gears or bevel gears, and the driven gear 71 is used as an intermediate gear to change the extension direction of the wheel axles corresponding to each gear except the transmission gear 51, so as to reasonably utilize the internal space of the equipment body, and the gear parameters can be adjusted according to actual needs to adapt to different application scenarios.
