DETAILED DESCRIPTION

[0035] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0036] Reference Figures 1-3 A contact lens mold material receiving positioning mechanism, comprising: base 1, material receiving positioning assembly 2, driving assembly 4 and limiting assembly 3. The material receiving positioning assembly 2 is movably arranged horizontally on the base 1, and has a plurality of clamping grooves 21 arranged horizontally and spaced apart along the moving direction of the material receiving positioning assembly 2, and the opening of the clamping groove 21 faces outward, and the clamping groove 21 is used for clamping the contact lens mold 7; the driving assembly 4 is arranged on the base 1, and the power output end of the driving assembly 4 is connected with the material receiving positioning assembly 2, and is used for driving the material receiving positioning assembly 2 to move horizontally; the limiting assembly 3 has a limiting plate 31 arranged on the opposite side of the clamping groove 21, and the limiting plate 31 is used for pressing and positioning the contact lens mold 7 in the clamping groove 21.

[0037] Understandably, base 1 is a mounting base component for other structures, such as a plate structure or a frame structure, but not limited to these. Slot 21 is a component that can accommodate and position the contact lens mold. The shape of slot 21 is adapted to the shape of the contact lens mold 7. For example, if the contact lens mold 7 is a cylindrical structure, then slot 21 is a semi-open cylindrical slot, etc. The horizontal movement of the receiving and positioning component 2 can adopt a sliding rail 5 and slider 22 cooperation structure, or a shaft hole guided cooperation structure, etc., but is not limited to these. The drive component 4 can adopt an electric push rod or lead screw drive, etc., but is not limited to these. The lifting and lowering setting of the limiting plate 31 can be achieved by a telescopic drive component 33 such as a cylinder or electric push rod for active lifting and lowering.

[0038] For reference, please refer to this setting. Figures 3-4 This utility model can be used in conjunction with the transmission device 9. The slot 21 can receive the contact lens mold 7 on the transmission device 9. Referring to Figures 5-6, the drive component 4 drives the entire receiving and positioning component 2 to move, so that the contact lens mold 7 on the transmission device 9 is inserted into the slot 21 one by one. The receiving and positioning component 2 moves towards the limiting plate 31, so that the limiting plate 31 presses against the side of the contact lens mold 7 and locks it in the slot 21 for positioning. In this way, it can be used in conjunction with the transmission device 9 and can also position multiple contact lens molds 7 at the same time, ensuring both efficiency and accuracy.

[0039] In some embodiments, reference Figures 1-3 The base 1 is equipped with a slide rail 5, and the receiving and positioning assembly 2 includes a slider 22 and a receiving plate 23. The slider 22 is slidably mounted on the slide rail 5 and connected to the power output end of the drive assembly 4. The receiving plate 23 is mounted on the slider 22, and the slots 21 are located on the side of the receiving plate 23 away from the slider 22. With this configuration, the drive assembly 4 can move the slider 22, which in turn moves the receiving plate 23, thereby moving each slot 21 to receive the contact lens mold 7.

[0040] In some embodiments, the limiting component 3 includes a fixing frame 32 and a telescopic drive member 33. The fixing frame 32 is disposed on the side of the base 1 near the slot 21; the telescopic drive member 33 is disposed on the fixing frame 32; wherein, the limiting plate 31 is disposed at the power output end of the telescopic drive member 33, thereby driving the limiting plate 31 to move down to be opposite the slot 21, and to move up to be above the side of the slot 21 to finish pressing and positioning the mold in the slot 21.

[0041] Understandably, the fixing frame 32 is a component that supports the entire limiting assembly. For example, it can be a structure of crossbeams and support rods, or a single or multiple upright plate structures that cooperate with the vertical movement of the limiting plate 31, etc., but is not limited to these. The telescopic drive component 33 can be a cylinder or an electric push rod, etc., but is not limited to these.

[0042] In this way, when the limiting plate 31 is opposite to the clamping groove 21, the limiting plate 31 can press and clamp the contact lens mold 7 in the clamping groove 21, so as to position the contact lens mold 7 and prevent it from falling off. When the clamp on the swing plate mechanism clamps the contact lens mold 7 in the clamping groove 21, the telescopic driving part 33 drives the limiting plate 31 to move upward, so as to end the positioning of the contact lens mold 7 and prepare for taking out the contact lens mold 7 by the swing plate mechanism.

[0043] In some embodiments, the length of the limiting plate 31 is greater than or equal to the length of the receiving plate 23. In this way, the limiting plate 31 can fully cover the clamping grooves 21 on the receiving plate 23, so as to ensure that the contact lens mold 7 in all clamping grooves 21 can be pressed and clamped.

[0044] In some embodiments, referring to Figures 2-4 , one side of the limiting plate 31 is provided with a sensor 8 located directly above the clamping groove 21, and the sensor 8 is used to detect whether there is a mold in the clamping groove 21. It can be understood that the sensor 8 can be fixed on the transmission device 9 or the fixing frame 32 through a connecting plate or other connecting member. The sensor 8 can be an optical sensor 8, a laser sensor 8 or a visual sensor 8, but is not limited thereto. Here, the sensor 8 needs to be used in cooperation with a control system. Specifically, when the contact lens mold 7 is clamped in the clamping groove 21, the sensor 8 detects and transmits an electrical signal to the control system, and the control system analyzes and controls the driving assembly 4 to drive the receiving and positioning assembly 2 to move, so as to move the next empty clamping groove 21 below the sensor 8, and the clamping groove 21 with the contact lens mold 7 is pressed and positioned by the limiting plate 31.

[0045] In some embodiments, referring to Figure 1 and Figure 6 , the receiving plate 23 on one side of the base plate is provided with a bearing plate 6 below for bearing the mold, and the bearing plate 6 is provided with a plurality of taking grooves 61 corresponding to the clamping grooves 21, and the openings of the taking grooves 61 are also outwardly arranged. Here, since the clamping groove 21 is a structure that penetrates up and down before entering the limiting plate 31, the contact lens mold 7 is easy to fall off from the bottom of the clamping groove 21. The bearing plate 6 can support the bottom of the contact lens mold 7 in the clamping groove 21, so that the limiting plate 31 does not need to press the contact lens mold 7 in the clamping groove 21, but only needs to position the contact lens mold 7. Further, the caliber of the taking groove 61 is smaller than the caliber of the clamping groove 21. Here, the outer diameter of the contact lens mold 7 is substantially the same as the caliber of the clamping groove 21, and the caliber of the taking groove 61 is also smaller than the outer diameter of the contact lens mold 7. In this way, when the contact lens mold 7 moves on the bearing plate 6, the contact lens mold 7 will not fall off from the taking groove 61.

[0046] In some embodiments, referring to Figures 3-4 The receiving and positioning mechanism further comprises a conveying mechanism for conveying the contact lens mold 7, and the conveying mechanism is provided with a limiting channel 91 for limiting and guiding the contact lens mold 7, and the output end of the limiting channel 91 corresponds to the clamping groove 21. In this way, the contact lens mold 7 is placed on the conveying device 9, the conveying device 9 drives the contact lens mold 7 to be guided and conveyed along the limiting channel 91, and finally conveyed to the clamping groove 21 from the end of the limiting channel 91, thereby realizing automatic receiving.

[0047] The above merely describes a preferred embodiment of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical scheme and improvement concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
