In the initial state, the vacuum suction cup 62 is located directly above the discharge end of the injection molding equipment.

Then the lifting member 7 drives the adsorption mechanism 6 to move upward, and then the first driving mechanism 3 is used to drive the optical lens to move from the injection molding equipment to the cutting equipment. After moving to the specified position, the optical lens is driven to move along the width direction of the frame 1 by the second driving mechanism 5 to move the optical lens to the installation station of the cutting equipment. Then the lifting member 7 is started to drive the optical lens to move downward until it is placed on the installation station, thereby completing the transfer process of the optical lens.

[0024] Reference Figure 2 As shown, the first driving mechanism 3 includes a driving motor 31, a lead screw 32 and a driving block 33.

The driving block 33 is fixedly arranged on the top of the first support plate 2 and is threadedly matched with the lead screw 32. The driving motor 31 drives the lead screw 32 to rotate, that is, the driving block 33 can be driven to drive the first support plate 2 to move along the length direction of the frame 1, thereby moving the optical lens from the injection molding device to the cutting device.

[0025] Reference Figure 1 , Figure 2 As shown, a slide groove 11 is provided on the frame 1 and on both sides of the top of the first support plate 2, and a slide bar 22 is provided on both sides of the top of the first support plate 2. A plurality of slide rollers 221 are distributed on the slide bar 22 along its length direction, and the slide rollers 221 are rollingly connected in the slide groove 11 to reduce the friction between the slide bar 22 and the slide groove 11, so as to make the driving process smoother.

[0026] Reference Figure 2 , Figure 3As shown, the second driving mechanism 5 includes a driving seat 51, which is slidably arranged at the bottom of the base 21, and is provided with a gear 52 and a rotating motor 53 for driving the gear 52 to rotate.

The gear 52 is located in the mounting groove 211 and meshes with the rack 212. The rotating motor 53 is started to drive the driving gear 52 to rotate. Under the meshing action of the rack 212, the driving gear 52 can drive the driving seat 51 to move along the length direction of the base 21 as a whole, so as to drive the optical lens to move along the width direction of the frame 1, so that the optical lens is moved to the installation position of the cutting equipment.

[0027] Reference Figure 2 As shown, the lifting member 7 includes a lifting electric cylinder 71, the cylinder barrel of the lifting electric cylinder 71 is fixedly mounted on the bottom of the second support plate 4, and a U-shaped seat 72 is provided on the piston rod of the lifting electric cylinder 71, and the U-shaped seat 72 is fixedly connected to the adsorption mechanism 6. When the lifting electric cylinder 71 is started and the piston rod of the lifting electric cylinder 71 moves out of or into the cylinder barrel, the adsorption mechanism 6 can be driven to move downward or upward through the U-shaped seat 72.

[0028] Reference Figure 2 , Figure 4 As shown, the adsorption mechanism 6 includes an adsorption seat 61 and a plurality of vacuum suction cups 62 arranged at the bottom of the adsorption seat 61, and a suction pump 63 for sucking the vacuum suction cups 62 to a negative pressure state is arranged on the adsorption seat 61.

An adsorption column 64 with a hollow interior is installed in the adsorption seat 61, and a plurality of vacuum suction cups 62 are distributed at the bottom of the adsorption column 64 along the circumferential direction of the adsorption column 64, and are connected to the adsorption column 64 through an adsorption branch pipe 65. The suction pump 63 is arranged on one side of the adsorption column 64 and is connected to the adsorption column 64 through an adsorption main pipe 66. The adsorption column 64 is sucked by the suction pump 63, that is, multiple vacuum suction cups 62 can be sucked to a negative pressure state at the same time through the adsorption column 64, so as to facilitate the adsorption of multiple optical lenses at the same time.

[0029] Reference Figure 4 As shown, the adsorption main pipe 66 and the adsorption branch pipe 65 are both threadedly connected to the adsorption column 64, and are both sealed with the adsorption column 64. The adsorption column 64 is provided with a bolt 641 and is detachably connected to the adsorption seat 61 through the bolt 641. Different specifications of optical lenses have different numbers of one-time molding during injection molding, so the vacuum suction cup 62 and the adsorption column 64 also need to be adjusted. For different numbers of optical lenses, replace the adsorption column 64 with a different number of connection ports, and then increase or decrease the number of vacuum suction cups 62 so that the number of vacuum suction cups 62 is consistent with the number of optical lenses that need to be adsorbed at one time.
