Technical Field

[0001] This application relates to the field of lens processing technology, and in particular to a lens mold making machine. Background Technology

[0002] Before casting the lens, molds A and B are fixed together with tape. During casting, liquid lens material is poured between molds A and B. After casting is completed and the lens material has solidified, the tape is removed. Then, the lens needs to be opened by separating molds A and B to facilitate lens separation.

[0003] In existing technologies, lens mold making is entirely manual: after the worker tears off the tape, they manually place the lens into a lens storage box, place mold A into mold A storage box, and mold B into mold B storage box. This method of lens mold making is inefficient. Summary of the Invention

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, this application provides a lens mold making machine 200, which includes a conveyor belt 21 and a mold making mechanism 22.

[0029] The mold opening mechanism 22 includes a clamping member 221, a circular blade 222, and a circular blade rotation drive component 223. The clamping member 221 and the circular blade 222 are respectively arranged on both sides of the conveyor belt 21 along the width direction.

[0030] A slide rail 224 is fixedly installed on the conveyor belt 21, and a clamping member 221 is slidably connected to the slide rail 224 along the width direction of the conveyor belt 21. In this application, the clamping member 221 is T-shaped, and the clamping member 221 moves away from the circular blade 222 until the end of the clamping member 221 abuts against the slide rail 224, which can play a limiting role for the clamping member 221.

[0031] like Figure 3 and Figure 4 As shown, the circular blade rotation drive component 223 is connected to the circular blade 222 to drive the circular blade 222 to rotate. In this application, the circular blade rotation drive component 223 is a rotary motor or the like. The rotary motor is fixedly mounted on a rotary motor mounting bracket 225, which is fixedly mounted on the conveyor belt 21. The output shaft of the rotary motor is fixedly connected to the circular blade 222.

[0032] The worker removes the cured lens mold from the basket and tears off the tape wrapped around it, placing it on the conveyor belt 21. The worker pushes the clamping component 221, pressing the lens and mold between the circular blade 222 and the clamping component 221. The circular blade rotation drive component 223 drives the circular blade 222 to rotate. The circular blade 222 aligns with the gap between the lens and mold A, opening up mold A and the lens; the circular blade 222 aligns with the gap between the lens and mold B, opening up mold B and the lens, thus separating the lens from molds A and B. The worker places the lens in the lens storage frame 23 and places molds A and B on the conveyor belt 21. Compared to the traditional purely manual lens mold opening method, this application achieves semi-automation of lens mold opening, thus improving the efficiency of lens mold opening.

[0033] like Figure 5 As shown, in one implementation, the lens mold making machine 200 also includes a blanking mechanism 24. The blanking mechanism 24 includes a guide plate 241, a clamping member 242, and a clamping member translation drive component 243. In this application, the clamping member translation drive component 243 is a translation cylinder or the like. The guide plate 241 is mounted on the end of the conveyor belt 21 and is inclined downward relative to the conveyor belt 21. The clamping member translation drive component 243 is mounted on the guide plate 241 and is connected to the clamping member 242 to drive the clamping member 242 to translate along the width direction of the conveyor belt 21, thereby clamping or releasing the mold piece.

[0034] After the mold piece is conveyed from the conveyor belt 21, it enters the guide plate 241 and slides along the guide plate 241. The mold piece is clamped by the clamping member 242, which limits the mold piece and stops it from sliding down. After the clamping member 242 releases the mold piece, the mold piece falls off. Therefore, automatic unloading of the mold piece is realized, which improves the working efficiency of lens mold making.

[0035] As one implementation, the clamping member 242 is wedge-shaped, and a guide strip 244 is fixedly provided on the guide plate 241. The distance between the clamping member 242 and the guide strip 244 gradually narrows from top to bottom. Through the above arrangement, the clamping member 242 can cooperate with the guide strip 244 to clamp mold pieces of different sizes.

[0036] As one implementation, two clamping members 242 and two guide bars 244 are provided. The two guide bars 244 are installed in the middle of the guide plate 241 and arranged in a figure-eight shape. The two clamping members 242 are installed on both sides of the guide plate 241 along the width direction. When mold A and mold B are placed on the conveyor belt 21 along the width direction of the conveyor belt 21, mold A and mold B will fall between the two sets of clamping members 242 and guide bars 244 respectively, thereby realizing the classified storage of mold A and mold B.

[0037] As one implementation, the feeding mechanism 24 also includes an angle adjustment mechanism for the guide plate 241. The angle adjustment mechanism includes a fixed seat 245 and a rotating seat 246. The fixed seat 245 is fixedly mounted on the conveyor belt 21. The rotating seat 246 has an angle adjustment groove, which is fan-shaped. The fixed seat 245 has bolt holes. Bolts passing through the angle adjustment groove and bolt holes are used to fix the rotating seat 246 and the fixed seat 245 together. The guide plate 241 is fixedly mounted on the rotating seat 246. By fixing the bolts at different positions in the angle adjustment groove, the angle of the rotating seat 246 relative to the fixed seat 245 can be adjusted, thereby adjusting the tilt angle of the guide plate 241.

[0038] As one implementation, the lens mold-making machine 200 also includes a mold-parting plate 25, which is installed at the rear of the conveyor belt 21. The mold-parting plate 25 forms an A-mold conveying channel and a B-mold conveying channel on both sides, and its front end is a pointed tip. The mold-parting plate 25 guides the A-mold and B-mold on the conveyor belt 21, allowing the A-mold to enter the A-mold conveying channel and the B-mold to enter the B-mold conveying channel, thus causing the A-mold and B-mold to fall between two sets of clamping members 242 and guide bars 244 respectively.

[0039] In one implementation, a proximity switch 26 is provided at the rear of the conveyor belt 21. The proximity switch 26 is connected to a controller, which is connected to a clamping member translation drive component 243. The proximity switch 26 is used to detect the position of the mold piece. When the proximity switch 26 detects the mold piece, the clamping member translation drive component 243 drives the clamping member 242 to move towards the guide bar 244. When the mold piece is between the clamping member 242 and the guide bar 244, the mold piece will be limited and will not fall off.

[0040] As one implementation, the rear of the conveyor belt 21 is also provided with a mold piece limiting member 27 and a mold piece limiting member translation drive component 271. The mold piece limiting member translation drive component 271 is connected to the mold piece limiting member 27 to drive the mold piece limiting member 27 to translate along the width direction of the conveyor belt 21. In this application, the mold piece limiting member translation drive component 271 is a translation cylinder or the like. When the proximity switch 26 detects the mold piece, the mold piece limiting member translation drive component 271 drives the mold piece limiting member 27 to move towards the mold piece separating plate 25, so that the mold piece limiting member 27 blocks the mold piece; after the clamping member 242 releases the mold piece on the guide plate 241 and the mold piece falls, the mold piece limiting member 27 resets, so that the mold piece on the conveyor belt 21 falls onto the guide plate 241.

[0041] like Figure 6 and Figure 7 As shown, in one implementation, the lens mold-making machine also includes a framing mechanism 100, which includes: a storage frame 11, a storage frame placement platform 12, a first translation module 13 of the placement platform, and a second translation module 14 of the placement platform. The first translation module 13 and the second translation module 14 of the placement platform are ball screw linear modules, etc.

[0042] The storage frame 11 includes a plurality of storage position units 111, which are arranged in rows along a first direction and columns along a second direction. The storage frame 11 is placed on a storage frame placement platform 12. A first translation module 13 of the placement platform is connected to the storage frame placement platform 12 and drives the storage frame placement platform 12 to move along the first direction. A second translation module 14 of the placement platform is connected to the storage frame placement platform 12 and drives the storage frame placement platform 12 to move along the second direction. Specifically, the second translation module 14 of the placement platform is connected to the first translation module 13 of the placement platform to drive the first translation module 13 of the placement platform to move along the second direction, and then the first translation module 13 of the placement platform drives the storage frame placement platform 12 to move along the second direction.

[0043] It should be noted that both the first and second directions are horizontal and perpendicular to each other. Since several storage position units 111 are arranged, the first translation module 13 and the second translation module 14 of the placement platform can make any one of the storage position units 111 in the storage frame 11 reach directly below the lower end of the guide plate 22.

[0044] With the above settings, the framed storage of the templates can be achieved: the templates fall from the guide plate 22 into the storage position unit 111 in the storage frame 11. Each time a template falls, the second translation module 14 of the placement platform drives the storage frame placement platform 12 to move the storage frame 11 in the second direction, so that the next empty storage position unit 111 is located directly below the lower end of the guide plate 22, thereby allowing the next template to fall into the next empty storage position unit 111; when a row of storage position units 111 is full of templates, the first translation module 13 of the placement platform drives the storage frame placement platform 12 to move the storage frame 11 in the first direction, so that the next row of empty storage position units 111 is located directly below the lower end of the guide plate 22, thereby allowing the next template to fall into the next empty storage position unit 111.

[0045] Therefore, this application does not require a gripping mechanism to grip the template, which can avoid misalignment or collision of the template in the storage frame 11.

[0046] In one implementation, the storage frame 11 includes several support members 112. Each support member 112 is elongated and spaced apart along a first direction, and parallel to each other. Several storage slots 1111 are formed on one side of each support member 112 near an adjacent support member 112. These storage slots are spaced apart along a second direction, and storage position units 111 are formed between two opposite storage slots on adjacent support members 112, allowing the several storage position units 111 to be arranged in a specific configuration. Furthermore, different support members 112 can be replaced or the spacing between the support members 112 can be adjusted according to the size and thickness of different mold pieces, thereby enabling the storage frame 11 to adapt to different types of mold pieces and reducing the cost of the framing mechanism 100.

[0047] Specifically, the storage frame 11 also includes a frame 113, which surrounds several support components 112 and is used to install and fix the support components 112.

[0048] It should be noted that the storage frame 11 can also be constructed by welding and fixing a frame 113 and several supporting components 112.

[0049] As one implementation, the framing mechanism 100 further includes a plurality of limiting components 15, which are installed at the bottom of the storage frame placement platform 12. The limiting components 15 are at least located at one end of the storage frame 11 along a first direction, and at least at one end of the storage frame 11 along a second direction. When the first translation module 13 of the placement platform drives the storage frame placement platform 12 to move the storage frame 11 in the first direction, the limiting components 15 at one end of the storage frame 11 along the first direction abut against the storage frame 11 to prevent relative slippage between the storage frame 11 and the storage frame placement platform 12; when the second translation module 14 of the placement platform drives the storage frame placement platform 12 to move the storage frame 11 in the second direction, the limiting components 15 at one end of the storage frame 11 along the second direction abut against the storage frame 11 to prevent relative slippage between the storage frame 11 and the storage frame placement platform 12.

[0050] Specifically, the limiting component 15 is a corner cylinder, etc. For example, the corner cylinder model is ACKL / ACKR25 / 32 / 40 / 50 / 63X90X180, etc. The corner cylinder includes a rotary cylinder 151 and a limiting rod 152. The rotary cylinder 151 is fixedly installed at the bottom of the storage frame placement platform 12, and the output shaft of the rotary cylinder 151 is fixedly connected to the limiting rod 152. When the rotary cylinder 151 drives the limiting rod 152 to rotate below the upper surface of the storage frame placement platform 12, the limiting component 15 no longer limits the storage frame 11, allowing the storage frame 11 to be pushed into or pushed out of the storage frame placement platform 12 along the first or second direction; when the rotary cylinder 151 drives the limiting rod 152 to rotate above the upper surface of the storage frame placement platform 12, the limiting component 15 limits the storage frame 11.
