[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0017] like Figure 1 As shown, the present application provides a lens mold-casting integrated machine, which includes: a loading machine 11, a mold-casting machine 12, a casting machine 13 and a blanking machine 14. Figure 1 Up, down, left, right, front and back directions as shown.

[0018] The loader 11 is used to load the lens molds A and B. In the manufacture of optical lenses, the lens molds A and B refer to molds used in pairs, corresponding to the two sides of the lens, respectively. The loader 11 is connected to the mold clamping machine 12 to input the lens molds A and B into the mold clamping machine 12. The mold clamping machine 12 is used to clamp the lens molds A and B. In the manufacture of optical lenses, lens clamping refers to fixing the molds A and B relative to each other to form a cavity for molding the lens. The mold clamping machine 12 is connected to the casting machine 13, which feeds the clamped lens mold into the casting machine 13. The casting machine 13 is used to cast the lens. In the manufacture of optical lenses, lens casting refers to the process of injecting liquid material (such as resin, molten glass, etc.) into the mold cavity and forming the lens after solidification or cooling. The casting machine 13 is connected to the blanking machine 14, which feeds the casted lens into the blanking machine 14. The blanking machine 14 is used for blanking and framing the cast lenses.

[0019] like Figure 2As shown, the loader 11 includes a sheet picking mechanism, an A-mold loading belt 118, and a B-mold loading belt 119. The A-mold loading belt 118 and the B-mold loading belt 119 are arranged one above the other, and the B-mold loading belt 119 at least partially extends relative to the A-mold loading belt 118. The sheet picking mechanism is used to grab the A-mold in the A-mold frame and place it on the A-mold loading belt 118. The sheet picking mechanism is also used to grab the B-mold in the B-mold frame and place it on the B-mold loading belt 119.

[0020] More specifically, the film picking mechanism includes a robot arm 11a, a suction cup frame 11b and a plurality of suction cups 11c.

[0021] The manipulator 11a includes a first swing arm 11a1 and a second swing arm 11a2. The first end of the swing arm 11a1 is fixedly connected to a first rotating shaft, which is connected to a rotation drive mechanism for the first rotating shaft. The second end of the swing arm 11a1 is fixedly connected to a second rotating shaft. The second end of the swing arm 11a2 is fixedly connected to a third end and a fourth end. The second rotating shaft is fixedly connected to the third end of the swing arm 11a2, which is connected to a rotation drive mechanism for the second rotating shaft. The rotation drive mechanisms for the first and second swing arms 11a1 and 11a2 are each a rotary motor, for example. The fourth end of the swing arm 11a2 is rotatably connected to a third rotating shaft. The axial directions of the first, second, and third rotating shafts are all in the vertical direction. The lower end of the third rotating shaft is fixedly connected to a connecting frame 11d. The third rotating shaft is telescopically connected to the second swing arm 11a2 in the up-down direction. As an implementation method, the third rotating shaft is connected to a lifting motor for driving the third rotating shaft to rise and fall.

[0022] Connecting frame 11d is rotatably connected to suction cup frame 11b, which is fixedly mounted on a fourth rotating shaft. The fourth rotating shaft is rotatably connected to connecting frame 11d, with the axial direction of the fourth rotating shaft being horizontal. A rotation drive mechanism for suction cup frame 11b is connected to the fourth rotating shaft, which is used to drive the fourth rotating shaft. The rotation drive mechanism for suction cup frame 11b is, for example, a rotary cylinder. Several suction cups 11c are fixedly mounted side by side on suction cup frame 11b.

[0023] The above-mentioned film picking mechanism adopts a graded transmission system of swing arm 11a1 and swing arm 2 11a2, which improves the flexibility of the film picking mechanism so that the A mold and the B mold can be quickly placed from the A mold frame and the B mold frame to the film feeding mechanism.

[0024] The suction cup holder 11b's rotary drive mechanism drives the suction cup 11c to flip 180 degrees. The lens molding surfaces of lens molds A and B are oriented in different directions, and the suction cup 11c needs to absorb the non-lens molding surfaces of the lens molds A and B. Therefore, the suction cup holder 11b's rotary drive mechanism drives the suction cup 11c to flip 180 degrees to absorb the lens molds A and B, respectively. When the film picking mechanism absorbs the lens molds A and B within the mold frames A and B via the suction cup 11c, the suction cup holder 11b's rotary drive mechanism drives the suction cup 11c to rotate so that the suction cup 11c vertically absorbs the lens molds A and B. When the film picking mechanism moves the lens molds A and B to the mold A loading belt 118 and the mold B loading belt 119 for flat placement, the suction cup holder 11b's rotary drive mechanism drives the suction cup 11c to rotate so that the suction cups horizontally place the lens molds A and B.

[0025] In another embodiment, the manipulator 11a can be replaced by a three-axis gantry, which drives the connecting frame 11d to move in the front-to-back direction, the left-to-right direction, and the up-down direction.

[0026] Furthermore, the loader 11 also includes a cleaning mechanism. The sheet picking mechanism first grabs the A mold in the A mold frame and grabs the B mold in the B mold frame and places them on the cleaning mechanism. After the cleaning mechanism performs surface treatment on the A mold and the B mold respectively, the sheet picking mechanism places the A mold and the B mold on the A mold loading belt 118 and the B mold loading belt 119 respectively.

[0027] Furthermore, the loading machine 11 further includes a frame feeding mechanism, which includes an A-frame conveyor belt 111, a B-frame conveyor belt 112, an A-frame placement platform 113, and a B-frame placement platform 114. The A-frame conveyor belt 111 and the B-frame conveyor belt 112 are arranged on the left and right sides.

[0028] The A-frame conveyor belt 111 includes an A-frame infeed conveyor belt 1111 and an A-frame outfeed conveyor belt 1112, which are arranged vertically. The B-frame conveyor belt 112 includes a B-frame infeed conveyor belt 1121 and a B-frame outfeed conveyor belt 1122, which are arranged vertically. The A-frame infeed conveyor belt 1111, the A-frame outfeed conveyor belt 1112, the B-frame infeed conveyor belt 1121, and the B-frame outfeed conveyor belt 1122 are each driven by a separate drive motor.

[0029] The A mold frame placement table 113 and the B mold frame placement table 114 are respectively arranged behind the A mold frame conveyor belt 111 and the B mold frame feed conveyor belt. The A mold frame placement table 113 includes the A mold frame feed conveyor belt 1131, and the B mold frame placement table 114 includes the B mold frame feed conveyor belt 1141.

[0030] The A-frame in-and-out conveyor belts 1131 and 1141 are connected to forward and reverse motors 116. The A-frame placement platforms 113 and 114 are connected to platform lift cylinders 117 at their bottoms. These lift cylinders 117 are used to drive the A-frame placement platforms 113 and 114 upward and downward, allowing the A-frame placement platforms 113 to connect to the A-frame in-feed conveyor belts 1111 and the A-frame out-feed conveyor belts 1112, respectively, while the B-frame placement platforms 114 connect to the B-frame in-feed conveyor belts 1121 and the B-frame out-feed conveyor belts 1122, respectively.

[0031] Furthermore, the loader 11 also includes a B-mold ejection mechanism. A-mold loading belt 118 and B-mold loading belt 119 are arranged one above the other. Both A-mold loading belt 118 and B-mold loading belt 119 comprise two parallel belts. The B-mold ejection mechanism is located at one end of B-mold loading belt 119. The B-mold is placed on B-mold loading belt 119, where it is ejected and then transported by B-mold loading belt 119.

[0032] The B-mold ejection mechanism is set because: since the lens has an arc-shaped surface, the A-mold and the B-mold also have an arc-shaped surface; during transportation, the molding surfaces of the A-mold and the B-mold used for lens molding face upward to avoid damage caused by friction between the molding surfaces of the A-mold and the B-mold and the conveyor belt; the molding surface of the A-mold is concave, and its outer surface is convex, so the A-mold can be in good contact with the A-mold loading belt 118 and transported smoothly during transportation; but the molding surface of the B-mold is convex, and its outer surface is concave, so the B-mold may have a position deviation with the B-mold loading belt 119 during transportation, resulting in the B-mold not being in good contact with the B-mold loading belt 119; the B-mold ejection mechanism is set to eject and position the B-mold to the middle of the B-mold loading belt 119, so that the B-mold can be in good contact with the B-mold loading belt 119 and transported smoothly during transportation.

[0033] The B-mold ejection mechanism includes a B-mold top plate, several top sheet blocks 11e, and a top sheet cylinder. The top sheet cylinder drives the B-mold top plate up and down. The top sheet blocks 11e are fixed to the B-mold top plate and lift the B-mold, positioning it in the center of the B-mold loading belt 119.

[0034] The A mold frame inlet conveyor belt 1111 and the B mold frame inlet conveyor belt 1121 convey the A mold frame and the B mold frame, and the A mold frame inlet and outlet conveyor belt 1131 and the B mold frame inlet and outlet conveyor belt 1141 convey the A mold frame and the B mold frame to the A mold frame placement table 113 and the B mold frame placement table 114; the placement table lifting cylinder 117 drives the A mold frame placement table 113 and the B mold frame placement table 114 to descend and align with the A mold frame outlet conveyor belt 1112 and the B mold frame outlet conveyor belt 1122; the picking mechanism sucks the mold frame by the suction cup The A mold and the B mold in the A mold frame and the B mold frame on the A mold frame placement table 113 and the B mold frame placement table 114 are placed on the A mold loading belt 118 and the B mold loading belt 119 and sent to the subsequent workstation; after the A mold and the B mold in the A mold frame and the B mold frame are taken out, the forward and reverse motor 116 is turned over, and the empty A mold frame is sent out through the A mold frame in-out conveyor belt 1131 and the A mold frame out-of-frame conveyor belt 1112, and the empty B mold frame is sent out through the B mold frame in-out conveyor belt 1141 and the B mold frame out-of-frame conveyor belt 1122.

[0035] like Figure 3 、 Figure 4 and Figure 5 As shown, the mold clamping machine 12 includes an A-mold feed belt 121 , a B-mold feed belt 122 , a positioning mechanism 123 , a mold clamping mechanism 124 and a mold clamping discharge belt 126 .

[0036] The A-mold feed belt 121 is connected to the A-mold loading belt 118, and the B-mold feed belt 122 is connected to the B-mold loading belt 119. In this application, the A-mold loading belt 118 is perpendicular to the A-mold feed belt 121, and the B-mold loading belt 119 is perpendicular to the B-mold feed belt 122.

[0037] The lens mold combining and casting integrated machine also includes an A-mold positioning and placing mechanism and a B-mold positioning and placing mechanism. The A-mold positioning and placing mechanism is used to grab the A-mold of the A-mold loading belt 118 and place it in the middle of the A-mold feeding belt 121. The B-mold positioning and placing mechanism is used to grab the B-mold of the B-mold loading belt 119 and place it in the middle of the B-mold feeding belt 122.

[0038] The A-mold positioning and placing mechanism includes a positioning clamp 127, a positioning clamp 1 opening and closing cylinder 128, a suction cup 2 129, a suction cup 2 translation mechanism 12a, and a suction cup 2 lifting mechanism 12b, which are arranged at the end of the A-mold feeding belt 118. The positioning clamp 1 opening and closing cylinder 128 is connected to the positioning clamp 127 to drive the positioning clamp 127 to open and close along the width direction of the A-mold feeding belt 118 so that the A-mold is positioned. The suction cup 2 translation mechanism 12a is connected to the suction cup 2 129 to drive the suction cup 2 129 to translate along the length direction of the A-mold feeding belt 118, and the suction cup 2 lifting mechanism 12b is connected to the suction cup 2 129 to drive the suction cup 2 129 to lift and lower. In this application, the suction cup 2 translation mechanism 12a is a translation motor, etc., and the suction cup 2 lifting mechanism 12b is a lifting cylinder, etc. The second suction cup 129 descends to absorb mold A, then ascends and translates to above the mold A feed belt 121. The second suction cup 129 then descends to place mold A on the mold A feed belt 121.

[0056] It should be noted that, since the lens casting speed is much slower than the lens mold closing speed, the lens mold after mold closing will stay on the conveyor belt for a long time waiting for casting. Therefore, the present application sets up two sets of casting machines 13 to improve the casting efficiency of the lens, thereby improving the lens production efficiency of the lens mold closing and casting machine. Only the mold picking and placing mechanism is set at the front end of the mold casting feed belt 131 of the first set of casting machines 13, such as Figure 8 As shown, the mold pouring feeding of the second group of pouring machines 13 does not have a mold picking and placing mechanism, and the remaining structures of the second group of pouring machines 13 are the same as those of the first group of pouring machines 13. The mold pouring feeding belts 131 of the two groups of pouring machines 13 are connected, and the mold pouring discharging belts 132 of the two groups of pouring machines 13 are connected.

[0059] Furthermore, the blanking machine 14 further includes an upper and lower frame mechanism, which includes a mold frame placement rack 147, a mold frame support plate 148, a support plate lifting mechanism 149, and a mold frame translation mechanism.

[0060] The mold frames are placed vertically at intervals on the mold frame placement rack 147, and the front and rear sides of the mold frame placement rack 147 are provided with cross bars for supporting the mold frames. The mold frame placement rack 147 is placed on the mold frame support plate 148.

[0061] Exemplarily, the mold frame fixing mechanism 14a includes a hook and a hook opening and closing cylinder. The hook opening and closing cylinder is connected to the hook to drive the hook to rotate and thus open and close. When the hook is open, the mold frame fixing mechanism 14a is relatively separated from the mold frame. When the hook is closed, the mold frame fixing mechanism 14a is relatively fixed to the mold frame.

[0062] The mold frame translation cylinder 14f drives the mold frame fixing mechanism 14a to move to the bottom of a mold frame on the mold frame placement rack 147; the hook opening and closing cylinder drives the hook to close, so that the mold frame and the mold frame fixing mechanism 14a are relatively fixed; the mold frame translation cylinder 14f drives the mold frame fixing mechanism 14a to translate to the left, so that the mold frame fixing mechanism 14a drives the mold frame to translate to the left, thereby making the mold frame detach from the mold frame placement rack 147; the mold picking mechanism picks up the mold The mold is placed horizontally on the blanking belt 141. After the mold is turned over to a certain angle, it is placed tilted or vertically in the mold frame; the mold frame fixing mechanism 14a drives the mold frame to move horizontally to the right, and then the hook opening and closing cylinder drives the hook to open, so that the mold frame filled with molds is placed back on the mold frame placement rack 147; the support plate lifting mechanism 149 drives the mold frame support plate 148 to rise or fall, and repeat the above actions to install the mold on the next mold frame until the mold frame on the mold frame placement rack 147 is full of molds.

[0063] A plurality of roller shafts 14b are respectively provided on the front and rear sides of the mold frame fixing mechanism 14a. The plurality of roller shafts 14b are used to guide the mold frame during translation.

[0064] Furthermore, the blanking machine 14 further includes a mold storage belt 14d, which is docked with the mold blanking belt 141 and has a stopper component at its end. The mold storage belt 14d is used to store molds that are not placed in the mold frame when the mold frame is replaced.

[0065] Furthermore, the blanking machine 14 includes two pivot cylinders 14e, each fixedly mounted on opposite sides of a mold frame support 147. These cylinders 14e comprise a cylinder body and a pivot arm, which drives the pivot arm 90°. When the pivot arm is rotated to a horizontal position, the mold frame support 147 is locked and cannot be removed. When the pivot arm is rotated to a vertical position, the mold frame support 147 can be removed and replaced.

[0066] The lens mold-casting machine of this application has the following working process: 1. Loading machine 11: 1.1. Use the A-frame infeed conveyor 1111 and the B-frame infeed conveyor 1121 to transport the A-frame and the B-frame. Then, use the A-frame inlet and outlet conveyor 1131 and the B-frame inlet and outlet conveyor 1141 to transport the A-frame and the B-frame to the A-frame placement table 113 and the B-frame placement table 114. 1.2. The placement platform lifting cylinder 117 drives the A mold frame placement platform 113 and the B mold frame placement platform 114 to descend, aligning with the A mold frame outgoing conveyor belt 1112 and the B mold frame outgoing conveyor belt 1122; 1.3, the picking mechanism uses the suction cup 11c to pick up the A mold and B mold from the A mold frame and B mold frame on the A mold frame placement table 113 and the B mold frame placement table 114, and places them on the A mold conveyor belt 1 and the B mold conveyor belt 1 to be sent to the subsequent station; 1.4. After the A and B molds in the A and B mold frames are taken out, the forward and reverse motors 116 are reversed, and the empty A mold frame is sent out through the A mold frame in-out conveyor belt 1131 and the A mold frame out-of-frame conveyor belt 1112, and the empty B mold frame is sent out through the B mold frame in-out conveyor belt 1141 and the B mold frame out-of-frame conveyor belt 1122.

[0067] 2. Clamping machine 12 clamping: 2.1. The A-mold positioning and placement mechanism places the A-mold on the A-mold feeding belt 121. The A-mold feeding belt 121 transports the A-mold to its rear end where it is positioned by the positioning cylinder. The A-mold suction cylinder then drives the A-mold suction cup to descend and hold the A-mold. The A-mold feeding cylinder then operates to deliver the A-mold to the A-mold positioning arm. 2.2. The B-mold positioning and placement mechanism places the B-mold on the B-mold feeding belt 122. The B-mold is transported by the B-mold feeding belt 122 to the rear end positioning cylinder for positioning. The B-mold loading cylinder loads the B-mold in two stages. The first stage is to rise and drive the B-mold to rotate through the B-mold rotating device. The visual positioning camera finds the scale line on the B-mold lens to perform position correction. After that, the second stage is to rise and place the B-mold in the B-mold positioning arm. 2.3. The A mold positioning arm and the A mold center positioning cylinder clamp the A mold. After the B mold center positioning cylinder and the B mold positioning arm clamp the B mold, the B mold center positioning cylinder is emptied and the locking cylinder is locked and positioned. After that, the B mold loading cylinder loads the B mold for the second time. 2.4. The B-mold is provided with positioning scale lines on its circumference. The image of the object captured by the visual positioning camera is transmitted to the CPU image processing system. The image processing positioning software calculates the B-mold offset position based on the positioning scale lines. This is then fed back to the motion control circuit via the interface circuit. The B-mold rotation device drives the B-mold to rotate and complete the deviation correction function. 2.5, the positioning mechanism 123 moves as a whole to the position of the mold clamping mechanism 124 on the left or right side; 2.6. The upper spindle 12m and the lower spindle 12o move relative to each other driven by the servo motor. The upper suction wheel 12n and the lower suction wheel 12p on the upper spindle 12m and the lower spindle 12o suck the mold A and mold B. At this time, the mold A positioning arm and the mold B positioning arm and the center positioning cylinder of the positioning mechanism 123 are released. The upper spindle 12m and the lower spindle 12o move in opposite directions. According to the set center thickness, when the upper spindle 12m and the lower spindle 12o move into place, they stop. 2.7, the tape cutting and sucking mechanism reaches the working position, and tape is applied to molds A and B. Then the upper spindle 12m and the lower spindle 12o rotate synchronously through the stepper motor to complete the tape wrapping, and the tape cutting blade cuts the tape. At the same time, the tape folding cylinder is actuated to complete the mold closing work; 2.8. Return of the positioning mechanism 123 during the mold closing process. When the upper spindle 12m and the lower spindle 12o adsorb the A and B molds on the positioning mechanism 123, the A and B molds return, and the positioning mechanism 123 returns to carry out the next step of the film feeding and positioning process, and transports the A and B molds positioned in the next step to the mold closing mechanism 124 position on the other side.

[0068] 2.9, the lower spindle 12° is retracted, and the manufactured resin lens together with the mold is placed on the mold closing and discharging belt 126 and then output.

[0069] 3. Pouring by pouring machine 13: 3.1, the mold pick-up and placement mechanism places the mold after mold closing on the mold casting feed belt 131, and the mold casting feed belt 131 transports the mold; 3.2, the suction cup 3 138 of the mold lifting mechanism descends, sucking the mold from the mold casting feed belt 131, and the clamping claws of the mold rotation and translation mechanism grab the mold and rotate the mold from a horizontal state 90° to a vertical state for pouring; 3.2. The mold rotation and translation mechanism delivers the mold to the tooling suction cup 13e. The tooling suction cup 13e absorbs the mold on the mold rotation and translation mechanism. The divider drives the tooling suction cup 13e to rotate so that the pouring gate of the mold faces upward. 3.3, the tape tearing mechanism 13f tears the tape head to expose the pouring port; 3.4, the casting mechanism performs lens casting; 3.5, after pouring is completed, the tape head mechanism 13h makes the tape head seal the pouring port; 3.6. The clamping claws of the mold rotation and translation mechanism grab the mold and rotate the mold from a vertical state 90° to a horizontal state. The suction cup 3 138 of the mold lifting mechanism sucks the mold and places it on the mold casting discharge belt 132.

[0070] 4. Blanking machine 14 blanking: 4.1. The mold frame translation cylinder 14f drives the mold frame fixing mechanism 14a to move to the bottom of a mold frame on the mold frame placement rack 147; the hook opening and closing cylinder drives the hook to close, so that the mold frame and the mold frame fixing mechanism 14a are relatively fixed; 4.2, the mold frame translation cylinder 14f drives the mold frame fixing mechanism 14a to translate to the left, so that the mold frame fixing mechanism 14a drives the mold frame to translate to the left, thereby making the mold frame separate from the mold frame placement rack 147; 4.3. The mold picking mechanism picks up the mold placed horizontally on the mold unloading belt 141, flips the mold to a certain angle, and then places the mold in a tilted or vertical position in the mold frame; 4.4, the mold frame fixing mechanism 14a drives the mold frame to move horizontally to the right, and then the hook opening and closing cylinder drives the hook to open, so that the mold frame filled with molds is returned to the mold frame placement rack 147; 4.5.
