DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] like Figure 1-3 As shown, one embodiment of the present invention discloses an automatic lens film and lens separation device, comprising two symmetrically arranged support plates 10, an intermediate support plate 11 is arranged between the two support plates 10, and both ends of the intermediate support plate 11 are rotatably connected to one side of the two support plates 10 respectively;

[0042] The lenses 7 are placed on the upper surfaces of the two support plates 10, the length direction of the lenses 7 is parallel to the width direction of the support plates 10, and the length of a single lens 7 is greater than the width of the support plates 10; a lens film 8 is attached to the side of the lens close to the support plates 10; and a suction mechanism for sucking the lenses 7 is provided at the bottom of the two support plates 10;

[0043] The structure of the lens for separating the lens and the lens film by the automatic separation device provided by the embodiment of the present invention can also be that the same side of the two lenses is covered with the same lens film so that the two lenses form a lens group, and the structure of the lens group is as follows: Figure 4 As shown in FIG. 1 , when separating the lens and the lens film of the lens group, the lenses on both sides of a single lens group are placed on two support plates respectively, and the two ends of the lens film under the lens group are respectively arranged on the two support plates and the middle part of the lens film is covered on the middle support plate, that is, Figure 5 As shown, the embodiment of the present invention separates the lens and the lens film of the lens in the form of a lens group structure.

[0044] It is further explained that the two support plates 10 of this embodiment are provided with a clamping mechanism 2, a flipping mechanism 3 and a separation mechanism 4 on one side away from the middle support plate 11, and the clamping mechanism 2 and the support plates 10 clamp the lens 7 in the middle;

[0045] After the lens is clamped, the flipping mechanism 3 is rotated to make part of the lens film 8 detach from the lens 7 along the length direction of the lens 7, and then the separation mechanism 4 is used to suck the uncoated side of the lens and rotate the separation mechanism 4 to completely separate the lens 7 from the lens film 8.

[0046] The embodiment of the present invention separates a part of the lens film from the lens through the flipping mechanism, and then separates the other part of the lens film through the separation mechanism, thereby realizing automatic separation of the lens film from the lens, and then realizing the separation of the lenses.

[0047] In this embodiment, the suction mechanism includes a vacuum plate 50, which is fixedly arranged below the support plate 50. A hole is arranged at the lower end of the vacuum plate 50, and the hole is connected to a negative pressure device. The support plate 10 is provided with a plurality of suction holes that penetrate the support plate 10 in the vertical direction, and the suction holes are connected to the holes.

[0048] In the embodiment of the present invention, the hole is connected to the negative pressure device through a pipeline, and the negative pressure device is started. Since the support plate is provided with adsorption holes connected to the hole, the lens is adsorbed on the upper surface of the support plate by negative pressure.

[0049] In this embodiment, each clamping mechanism 2 includes a pressing plate 20, which is rotatably connected to the rotating mechanism through a rotating shaft. The rotating mechanism includes a driving cylinder 21 and a connecting block 22. The movable end of the driving cylinder 21 is fixedly connected to one end of the connecting block 22, and the connecting block 22 is hinged to one side of the support plate through a hinge block.

[0050] A rack 220 is disposed at the upper end of the connecting block 22 , and the rack 220 is meshed with a gear 23 located above the rack 220 , and the gear 23 is sleeved on the rotating shaft.

[0051] The embodiment of the present invention can start the driving cylinder and shrink the movable end of the driving cylinder. The shrinkage of the movable end of the cylinder drives the connecting block to move horizontally. The movable block moves so that the rack on the upper end of the movable block moves horizontally with the movable block, and then the gear meshing with the rack rotates. The rotation of the gear rotates the rotating shaft, and then the pressure plate rotates around the rotating shaft and contacts the side of the lens not covered with the lens film, thereby achieving the support plate and the pressure block sandwiching the lens in the middle to avoid deviation of the lens position when flipping.

[0052] In this embodiment, a plurality of pressing blocks 200 are fixedly disposed on the pressing plate 20 , and the plurality of pressing blocks 200 are distributed at equal intervals along the length direction of the pressing plate 20 .

[0053] The above arrangement of the embodiment of the present invention can realize that when multiple lenses are placed on the support plate, the lens films and lenses of the multiple lenses can be separated at the same time.

[0054] In this embodiment, if Figure 6-7 As shown, the flipping mechanism includes a pen-shaped cylinder 30, a swivel fork 31 and a support seat 32, one end of the swivel fork 31 is connected to the support seat 32, the other end of the swivel fork 31 is connected to the movable end of the pen-shaped cylinder 30, and the support seat 32 is fixedly connected to the bottom of the support plate 10.

[0055] In the embodiment of the present invention, the pen-shaped cylinder is activated and the movable end of the pen-shaped cylinder is retracted to drive the support plate, the lens adsorbed on the support plate, and the clamping mechanism pressing the other side of the lens to flip clockwise and stop flipping when the lens is in a vertical state. After flipping, the lens film that is not in contact with the surface of the support plate is separated from the lens. At this time, the state of the lens and the lens film is as follows: Figure 8 It should be noted that the lens film of this embodiment is an elastic film, and when the flipping mechanisms on both sides are simultaneously actuated to drive the lens to flip, the lens film will not be broken from the middle due to the flipping.

[0056] like Figure 9-12 As shown, the separation mechanism 4 in this embodiment includes two vacuum suction cups 40 that can vacuum suction the lens 7. The vacuum suction cups 40 are fixed on a bracket 41, and the bracket 41 is fixedly connected to the rotating arm.

[0057] The embodiment of the present invention sets a separation mechanism and rotates the rotating arm to make two vacuum suction cups suck the uncoated side of the lens, and then rotates the rotating arm to separate the part of the lens film that is not separated from the lens from the lens, thereby achieving complete separation of the lens film from the lens.

[0058] In this embodiment, a lens film and lens automatic separation device of this embodiment also includes a base 6, which is arranged below the middle support plate 11, and support vertical plates 60 are symmetrically arranged on both sides of the upper surface of the base 6, the bottoms of the two support vertical plates 60 are fixedly connected to the base 6, and the tops of the two support vertical plates 60 are respectively fixedly connected to the two sides of the middle support plate 11.

[0059] The embodiment of the present invention can support the separation device above by providing a base, so that the base and the separation device above the base form a structural whole.

[0060] In order to fix the pen-shaped cylinder, the two pen-shaped cylinders 30 of this embodiment are fixed on the upper surface of the base 6 through a connecting seat.

[0061] The embodiment of the present invention further discloses a separation method based on the above-mentioned lens film and lens automatic separation device, comprising the following steps:

[0062] S1: Place a plurality of lenses with the lens film facing downward on the support plate along the length direction of the support plate, as shown in Figure 1-3 and Figure 4-5 As shown, after the lens is placed, the lens is sucked onto the support plate through the suction mechanism;

[0063] S2: Start the driving cylinder and contract the movable end of the driving cylinder. The contraction of the movable end of the cylinder drives the connecting block to move horizontally. The movable block moves, causing the rack on the upper end of the movable block to move horizontally with the movable block, thereby causing the gear meshing with the rack to rotate. The rotation of the gear causes the rotating shaft to rotate, thereby causing the pressure plate to rotate around the rotating shaft, thereby causing the pressure plate to contact the side of the lens not covered with the lens film.

[0064] The clamping mechanism is rotated to make the pressing block press the side of the lens not covered with the lens film;

[0065] S3: Start the pen-shaped cylinder and retract the movable end of the pen-shaped cylinder to drive the support plate, the lens adsorbed on the support plate, and the clamping mechanism pressing the other side of the lens to flip together and stop flipping when the lens is in a vertical state. After flipping, the lens film on the part of the lens not covering the support plate is separated from the lens, that is, Figure 8-10 As shown;

[0066] S4: The clamping mechanism is rotated to separate the pressure plate from the lens;

[0067] S5: Figure 9-10 As shown, the rotating arm is rotated to allow two vacuum suction cups to suck the uncoated side of the lens;

[0068] S6: Figure 11-12 As shown, rotate the rotating arm to completely separate the lens from the lens film.

[0069] The embodiment of the present invention first sucks the side of the lens covered with the lens film through the suction mechanism, and then clamps the lens between the support plate and the clamping mechanism through the clamping mechanism, and then partially separates the lens film from the lens by rotating the flipping mechanism, and then sucks the side of the lens film not covered with the lens film through the vacuum suction cup of the separation mechanism and rotates the separation mechanism to completely separate the lens film from the lens, thereby realizing automatic separation of the lens, reducing labor intensity compared to the existing manual separation method, and improving separation efficiency and accuracy.

[0070] Finally, it should be noted that the above only describes in detail the specific embodiments of the present invention. However, the present invention is not limited to the specific embodiments described above. Equivalent modifications and substitutions made by those skilled in the art to the present invention are also within the scope of the present invention. Therefore, equal changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of the present invention.
