[0001] This utility model relates to the technical field of automated devices for eyeglass manufacturing, and more particularly to a casting mechanism for a lens casting device. Background Technology
[0002] In the manufacturing process of optical lenses, the casting process is a crucial step that directly affects the optical performance and appearance quality of the final lens. Traditional lens casting processes typically involve precisely injecting materials such as liquid resin into a mold and then curing it under specific conditions. However, with the ever-increasing demands on lens performance, traditional casting mechanisms are no longer sufficient to meet the needs of modern production.

This can easily lead to problems such as air bubbles and uneven material distribution during the casting process. Furthermore, these devices often lack the ability to monitor and adjust casting parameters in real time, resulting in fluctuations in product quality and affecting the optical performance and consistency of the lenses.

[0035] In a further embodiment of this invention, the lateral movement module 54 first moves the pouring head 51 to a designated position. The side detection camera 521 and the front detection camera 522 monitor the mold opening position and liquid level in real time to ensure the pouring head 51 is in the correct working state.

[0037] In a further embodiment of this utility model, the pouring head 51 is a KGN-ATV232 spray head. A hose is connected to the top of the pouring head 51, and external liquid is supplied to the pouring head 51 through the hose. The external liquid supply box is placed on a rack, which is not shown in the figure. The liquid suction component 59 is connected to the pouring head 51 but not in communication. There is an opening at the bottom of the liquid suction component 59, which is used to prevent the liquid from overflowing when the pouring is too full and to suck up the excess liquid at the mold opening.
[0038] In a further embodiment of this utility model, the flow rate regulating motor 551 drives the flow rate regulating column 552 to extend and retract, thereby squeezing the pouring pipe and changing the flow rate.
[0039] In a further embodiment of this utility model, the side detection camera 521 detects the position of the mold opening, the lateral movement module 54 and the lifting module 53 drive the pouring head 51 to move directly above the mold opening and start pouring liquid into the mold. The front detection camera 522 detects the liquid level height in the mold in real time. When the mold is full, the pouring head 51 stops pouring.
[0040] In a further embodiment of this utility model, by setting a side detection camera 521 and a front detection camera 522 to detect the mold opening position, the pouring position can be precisely controlled, effectively avoiding the generation of air bubbles during the pouring process.
[0041] In a further embodiment of this utility model, by setting the pouring flow rate adjustment module 55, the flow rate of the pouring liquid can be controlled, which is compatible with a variety of different formulas and effectively avoids the generation of product defects.
[0042] In a further embodiment of this utility model, by providing a liquid suction member 59, excess liquid can be absorbed by the pouring head 51 during the injection process into the mold, thus preventing residual liquid from dripping from the pouring head 51 and causing product defects.
[0043] In a further embodiment of this utility model, the position of the pouring liquid surface is detected by setting a side detection camera 521 and a front detection camera 522, thereby improving the pouring quality and the stability of product quality.
[0044] In a further embodiment of this utility model, the liquid suction component 59 is connected to the negative pressure suction device through the pouring pipe to realize the function of the liquid suction component 59 to suck the liquid poured inside the mold. The negative pressure suction device can be a negative pressure suction vacuum pump or other high-precision negative pressure suction device. The liquid sucked by the liquid suction component 59 can be directly returned to the external liquid supply tank, or it can be temporarily stored and processed before being transferred to the external liquid supply tank.
[0045] In a further embodiment of this utility model, the pouring head 51 is connected to the external liquid supply tank through a pouring pipe. A pump body is installed on the pouring pipe to draw liquid from the external liquid supply tank and then inject it into the mold through the pouring head 51. The pouring pipe is also equipped with a pouring flow rate adjustment module 55 for adjusting the cross-sectional area inside the pouring pipe, thereby adjusting the pouring speed of the pouring head 51 into the mold, which serves to change the flow rate inside the pouring pipe.
[0046] In a further embodiment of this utility model, a side detection camera 521 and a front detection camera 522 are respectively set on the side and front of the mold, and a light source 523 is set on the rear side of the mold. Even in a relatively dark environment, the side detection camera 521 and the front detection camera 522 can still detect the liquid level in the mold in real time. Setting the detection cameras in two directions can avoid the problem of unilateral obstruction during operation. At the same time, it can clearly know the positional relationship between the pouring head 51, the liquid suction component 59 and the mold opening in the horizontal direction, and avoid the situation where the pouring head 51 is difficult to adjust to the correct position to pour into the mold, or the liquid suction component 59 is difficult to adjust to the correct position to suck up the liquid in the mold.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
