The design of the composite suction pen 2211 being provided with a plurality of suction pens 2211 realizes the quick and accurate pick-and-place of a plurality of lenses in the mold 1, effectively improves the production efficiency, and solves the problem that the number of pick-and-place of a single suction pen in the existing traditional lens molding machine is small, resulting in low production efficiency.

[0022] For further information, see Figures 1 to 3 , a quick pick-up and placement structure for multi-hole molded lenses, the pick-up and placement component 22 includes a pick-up and placement bracket 222 connected to the mobile component 21, the composite suction pen 221 includes a suction pen bracket 2212 connected to the pick-up and placement bracket 222, the suction pen 2211 is arranged on the suction pen bracket 2212, and the pick-up and placement bracket 222 and the suction pen bracket 2212 are arranged perpendicular to each other.

At the same time, by setting the suction pen bracket 2212 perpendicular to the pick-up and placement bracket 222, the space utilization rate of the manipulator body 2 is optimized, and the compactness of the structure and the accuracy of operation are effectively improved.

[0023] For further information, see Figures 1 to 3, a quick pick-up and placement structure for multi-hole molded lenses, the pick-up and placement bracket 222 includes a protrusion 2221 connected to the bottom surface of the suction pen bracket 2212, the suction pen bracket 2212 is provided with a plurality of mounting holes 22121, the mounting holes 22121 pass through the suction pen bracket 2212 and the protrusion 2221, and the suction pen 2211 is located in the mounting hole 22121. The design of the protrusion 2221 enhances the connection strength and stability between the protrusion 2221 and the suction pen holder 2212. At the same time, the protrusion 2221 provides a deeper setting space for the mounting hole 22121. When the mounting hole 22121 passes through the suction pen holder 2212 and the protrusion 2221, the contact area between the suction pen 2211 and the mounting hole 22121 is larger, which provides a precise position for fixing the suction pen 2211 and makes the connection between the suction pen 2211 and the suction pen holder more stable. The suction pen 2211 is positioned by the mounting hole 22121, which is convenient for the installation and replacement of the suction pen 2211 and can ensure the precise alignment of the suction pen 2211 with the mold cavity 11, thereby effectively improving the working accuracy of the robot body 2.

[0024] For further information, see Figures 1 to 3 , a quick pick-up and placement structure for multi-cavity molded lenses, the pick-up and placement bracket 222 is provided with a plurality of alignment holes 2222 penetrating the suction pen bracket 2212 and the protrusion 2221, and the mold 1 is provided with alignment posts 12 corresponding to the alignment holes 2222.

[0025] For further information, see Figures 1 to 3, a quick pick-up and placement structure for multi-hole molded lenses, the suction pen 2211 and the suction pen holder 2212 are arranged perpendicular to each other, the suction pen 2211 includes a vacuum suction head 22111, a suction nozzle 22112 and a fastener 22113, the fastener 22113 is located between the suction pen holder 2212 and the suction pen 2211, so that the suction pen 2211 is fixed to the mounting hole 22121, and the vacuum suction head 22111 and the suction nozzle 22112 are connected to each other. The vacuum head 22111 is used to connect with an external vacuum source and is responsible for generating negative air pressure to adsorb the lens, while the suction nozzle 22112 is the part that directly contacts the lens. The connection between the suction nozzle 22112 and the vacuum head 22111 ensures the air path connection of the suction pen 2211, so that the vacuum suction force can be effectively transmitted to the suction nozzle 22112, thereby achieving stable adsorption and release of the lens. In addition, the fastener 22113 is used to fix the suction pen 2211 to the mounting hole 22121 on the suction pen bracket 2212, thereby ensuring the stability and reliability of the suction pen 2211 during operation. When the suction pen 2211 is working, the external vacuum source is connected to the vacuum head 22111, and the negative air pressure generated by the external vacuum source is transmitted to the suction nozzle 22112 through the vacuum head 22111, and the suction nozzle 22112 adsorbs the lens. When the external vacuum source no longer generates negative air pressure, the suction nozzle 22112 releases the lens.

[0026] For further information, see Figures 1 to 3 , a quick pick-and-place structure for multi-cavity molded lenses, the moving assembly 21 comprises a lifting cylinder 211, a lifting bracket 212 connected to the lifting cylinder 211, and a buffer cylinder 213 connected to the lifting bracket 212, and the buffer cylinder 213 is connected to the suction pen bracket 2212. With such a design, the lifting cylinder 211 enables the manipulator body 2 to obtain a driving force in the vertical direction, controls the rising and falling movements of the pick-and-place assembly 22 above the mold 1, and enables the manipulator body 2 to flexibly use different heights of the mold 1 for precise pick-and-place operations, the lifting bracket 212 is designed to transfer the linear motion of the lifting cylinder 211 to the lower structure, and the buffer cylinder 213 is used to provide a buffering effect at the end of the lifting action, by controlling the gas flow in the cylinder, absorbing the impact and vibration during the movement, so that the suction pen 2211 moves more gently when contacting the lens or leaving the mold, reducing damage to the lens or mold, and improving the stability and accuracy of the overall operation of the manipulator body 2.

[0027] For further information, see Figures 1 to 3, a quick pick-and-place structure for multi-cavity molded lenses, wherein the mold cavities 11 are evenly distributed along the circumference of the center of the mold 1. With such a design, the mold cavities 11 occupy the same angular position on the mold 1, ensuring that the thermoplastic material can be evenly filled into each mold cavity 11 during each molding, and can produce multiple identical lenses in a single molding cycle while ensuring the quality of the lenses, effectively improving production efficiency and maintaining production consistency.

[0028] For further information, see Figures 1 to 3 , a quick pick-and-place structure for multi-cavity molded lenses, further comprising a material tray 3, wherein the material tray 3 is provided with material tray cavities 31 corresponding one-to-one with the mold cavities 11. The one-to-one correspondence between the material tray cavities and the mold cavities can greatly improve the efficiency of subsequent processing steps, such as cooling, inspection and packaging, and can reduce the need for manual intervention, making the production process more automated and continuous. At the same time, the material tray cavities 31 are provided with labels, and in the later quality inspection stage, the quality can be traced according to the labels on the material tray cavities 31, and the corresponding mold cavities 11 can be found, which effectively optimizes the lens quality inspection system.

[0029] For further information, see Figures 1 to 3 , a quick pick-and-place structure for multi-cavity molded lenses, the suction nozzle 22112 is made of silicone and its diameter is less than or equal to the diameter of the mold cavity 11. The suction nozzle 22112 is made of silicone to obtain the characteristics of softness and high elasticity, which can ensure that the suction nozzle 22112 will not cause damage to the lens when contacting and sucking it, and silicone can withstand repeated bending and extrusion, has a long service life and is low in price. At the same time, silicone has a wide operating temperature range and good chemical stability, and can be used in more production environments. The diameter of the suction nozzle 22112 is less than or equal to the diameter of the mold cavity 11, which ensures that the suction nozzle 22112 can match the size of the lens, so that it is more stable and accurate during the suction process, avoiding the inability to effectively suck the lens due to the excessive size of the suction nozzle 22112, thereby causing the lens to fall off.

[0030] For further information, see Figures 1 to 3, a quick pick-and-place structure for multi-hole molded lenses, the diameter of the mounting hole 22121 is greater than or equal to the diameter of the suction pen 2211 and the number of the mounting holes 22121 is 16, and the alignment posts 12 are provided with 4 and symmetrically arranged along the circumference of the center of the mold 1. With such a design, the diameter of the mounting hole 22121 is greater than or equal to the diameter of the suction pen 2211, which can ensure that the suction pen 2211 can be firmly inserted into the mounting hole 22121 and fixed in the corresponding position, avoiding the difficulty of assembly caused by over-tightening, and the alignment posts 12 are provided with 4 and symmetrically arranged along the circumference of the center of the mold 1. The design is used to ensure the rapid and accurate alignment between the mold 1 and the pick-and-place assembly 22, providing accurate and efficient positioning for the suction pen 2211 to grab the lens, avoiding the failure of the suction pen 2211 to grab the lens due to inaccurate alignment, thereby causing damage to the lens.

[0031] Working principle: When the robot body 2 is working, the lifting cylinder 211 and the buffer cylinder 212 cooperate to move the suction pen holder 2212 to the top of the mold 1 and slowly downward. At this time, the alignment hole 2222 is aligned with the alignment column 12. When the suction nozzle 22112 contacts the lens, the negative air pressure generated by the external vacuum source is transmitted to the suction nozzle 22112 through the vacuum head 22111, and the suction nozzle 22112 adsorbs the lens. Further, the suction pen holder 2212 moves to the top of the material tray and the suction pen 2211 corresponds to the material tray hole 31 one by one. The external vacuum source no longer generates negative air pressure, and the suction nozzle 22112 releases the lens into the material tray hole 31.
