Description

Technical Field

[0001] This invention relates to the field of eyeglass manufacturing equipment technology, and in particular to an automatic processing equipment for the temples of acetate eyeglasses. Background Technology

[0002] In the production of acetate eyeglasses, the raw acetate material needs to be cut into blocks of the required size. The basic shapes of the frame and temples are then carved using a CNC machining center. Hinges are then inlaid on the frame and temples respectively, and the frames and temples are hinged together to form the eyeglasses. In the carving process of hanging the temples, since the size of a single piece of acetate is much larger than the material required for a single temple, the existing production process chooses to carve several temples on a single piece of acetate at the same time. However, in order to prevent the carved temple from breaking off from the acetate and affecting the carving of the next temple, a connection point needs to be left during carving. After the temple is removed from the carved acetate, the connection point is then polished. This adds an extra step to the process, reduces the overall production efficiency, and urgently needs improvement. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technologies, this invention provides an automatic processing device for temples in the production of acetate eyeglasses. The device includes a CNC machining unit for engraving the temples and an acetate feeding unit. The CNC machining unit and the acetate feeding unit are connected via a feeding conveyor belt assembly. The acetate feeding unit includes a pair of feeding conveyor belts for placing the adhesive board, a pair of limiting baffles, an automatic unloading mechanism for placing and dropping the acetate blocks onto the adhesive board, and a cutting mechanism. The pair of limiting baffles are symmetrically arranged on the feeding conveyor belts. The automatic unloading mechanism is located on the feeding conveyor belts and above the pair of limiting baffles. The automatic unloading device includes a lifting frame, a feeding limiting rod assembly matching the acetate blocks, a pusher plate, and a pusher cylinder. The lifting frame is located above the pair of limiting baffles, and the feeding limiting rod assembly is located on the lifting frame. The assembly has a passage notch near the connection point with the lifting frame, matching the shape and size of the eyeglass plate block. The passage notch is located between a pair of limiting baffles. The shape and size of the pusher plate match the passage notch. The pusher cylinder is fixedly mounted on the lifting frame and aligned with the passage notch. One end of the pusher plate is connected to the piston rod of the pusher cylinder. The cutting mechanism includes a mounting frame, a drive cylinder, and a cutting blade with a mounting rod. The mounting frame is fixedly mounted on the adjacent end tables of a pair of feeding conveyors. The drive cylinder is fixedly mounted on the top of the mounting frame. The mounting rod of the cutting blade is fixedly connected to the piston rod of the drive cylinder. The position of the cutting blade is aligned with the midpoint of the pair of feeding conveyors, and the blade direction is perpendicular to the running direction of the feeding conveyors. The pair of feeding conveyors, the pusher cylinder, and the drive cylinder are all electrically connected via a PLC controller.

[0004] Using the above technical solution, before the eyeglasses acetate blocks are CNC machined into temples, an adhesive plate is first attached to one side of the plate block. This ensures that even if no connection points are left during temple carving, the adhesive force of the plate prevents the carved temples from falling off the plate block. After carving all the temples on a plate block, the temples are manually removed from the adhesive plate. The system includes a plate feeding device comprising a pair of feeding conveyor belts for placing the adhesive plate, a pair of limit baffles, an automatic unloading mechanism for placing and dropping the eyeglasses acetate blocks onto the adhesive plate, and a cutting mechanism. The eyeglasses acetate blocks are batch-loaded onto the automatic unloading mechanism, and then the adhesive plate is placed on the feeding conveyor belt. The conveyor belt is set to pause after moving a given displacement distance. When the adhesive plate is on the feeding conveyor belt... When the material moves to below the automatic unloading mechanism, the pushing cylinder starts and controls the pushing plate to push the plate blocks stacked on the limit rod group down from the lifting frame one by one and land on the adhesive plate located between a pair of limit baffles. Then the conveyor belt starts again and moves a given displacement distance. This process is repeated, and the plate blocks move on the conveyor belt together with the adhesive plate. When the two eyeglass plate blocks on the adhesive plate move between a pair of feeding conveyor belts, the drive cylinder of the cutting mechanism starts and controls the cutting blade to press down, cutting the adhesive plate between the adjacent pair of eyeglass plate blocks, completing the adhesive plate pasting work on a single eyeglass plate block. After that, the plate block with the adhesive plate pasted on it is conveyed to the CNC machining device along the feeding conveyor belt and the loading conveyor belt, where the temples can be CNC machined, eliminating the grinding process of the temple connection point.

[0005] A further feature of the present invention is that an auxiliary cutting module is provided on the mounting rod of the cutting blade. The auxiliary cutting module includes a pressing cylinder, a connecting block, and a pair of tension springs. The pressing cylinder has a through hole that matches the mounting rod. Mounting cylinders for mounting tension springs are provided on both sides of the through hole. A pair of auxiliary pressure plates are symmetrically provided at the bottom of the pressing cylinder. The connecting block is fixedly mounted on the mounting rod. The pressing cylinder is sleeved on the mounting rod through the through hole. The two ends of the pair of tension springs are respectively connected to the pair of mounting cylinders and the connecting block.

[0006] Using the above technical solution, since the mounting rod of the cutting blade is equipped with an auxiliary cutting module, the auxiliary cutting module includes a pressing cylinder, a connecting block, and a pair of tension springs. The pressing cylinder has a through hole that matches the mounting rod, and mounting cylinders for mounting the tension springs are provided on both sides of the through hole. A pair of auxiliary pressure plates are symmetrically provided at the bottom of the pressing cylinder. The connecting block is fixedly set on the mounting rod. The pressing cylinder is sleeved on the mounting rod through the through hole. The two ends of the pair of tension springs are respectively connected to the pair of mounting cylinders and the connecting block. When the cutting blade is pressed down by the driving cylinder to cut, the pressing cylinder first contacts and presses down the surfaces of the two eyeglasses sheet blocks located on the pair of conveyor belts. Then the cutting blade falls. During the period when the pressing cylinder presses down on the falling cutting blade, the downward pressure of the pressing cylinder increases due to the action of the tension springs, ensuring that the two eyeglasses sheet blocks located on the pair of conveyor belts will not move when the cutting blade cuts the adhesive board, further ensuring the smooth progress of the cutting work.

[0007] A further feature of the present invention: The CNC machining device includes a CNC milling mechanism, a mounting base, a feeding plate, a feeding mechanism, and an automatic feeding and clamping mechanism for feeding the assembly of eyeglasses sheet and adhesive plate. The CNC milling mechanism, the automatic feeding and clamping mechanism, the feeding mechanism, and the feeding plate are all mounted on the mounting base. The automatic feeding and clamping mechanism includes a two-stage lifting frame, a two-stage feed limit rod group, a movable fixture table, a pusher fixture plate, several fixture table drive cylinders, and several fixture plate drive cylinders. The several fixture table drive cylinders are mounted on the mounting base. One end of the movable fixture table is connected to the piston rod of the several fixture table drive cylinders. The pusher fixture plate and the several fixture plate drive cylinders... All cylinders are mounted on the movable fixture platform. One end of the pusher fixture plate is connected to the piston rod of several fixture plate drive cylinders. The secondary lifting frame is mounted on the mounting base and located above the movable fixture platform and the pusher fixture plate. The secondary feeding limit rod group is fixedly connected to the secondary lifting frame. The end of the feeding conveyor belt group is aligned with the opening of the secondary feeding limit rod group. The end of the movable fixture platform is fixedly provided with a clamping stop. The discharge mechanism includes a discharge drive cylinder and a discharge push block. The discharge push block is connected to the piston rod of the discharge drive cylinder. The CNC milling mechanism, several fixture platform drive cylinders, discharge drive cylinders, and several fixture plate drive cylinders are all electrically connected through a PLC controller.

[0008] Using the above technical solution, the CNC machining device includes a CNC milling mechanism, a mounting base, a feeding plate, a feeding mechanism, and an automatic feeding and clamping mechanism for feeding the assembly of eyeglasses sheet and adhesive plate. The CNC milling mechanism, automatic feeding and clamping mechanism, feeding mechanism, and feeding plate are all mounted on the mounting base. The automatic feeding and clamping mechanism includes a two-stage lifting frame, a two-stage feed limit rod group, a movable fixture table, a pushing fixture plate, several fixture table drive cylinders, and several fixture plate drive cylinders. The several fixture table drive cylinders are mounted on the mounting base. One end of the movable fixture platform is connected to the piston rods of several fixture platform drive cylinders. The pushing fixture plate and several fixture plate drive cylinders are all mounted on the movable fixture platform. One end of the pushing fixture plate is connected to the piston rods of several fixture plate drive cylinders. The secondary lifting frame is mounted on the mounting base and located above the movable fixture platform and the pushing fixture plate. The secondary feeding limit rod group is fixedly connected to the secondary lifting frame. The end of the feeding conveyor belt group is aligned with the opening of the secondary feeding limit rod group. The end of the movable fixture platform is fixedly provided with a clamping stop. The discharge mechanism includes an outlet... The system includes a material-driven cylinder and a discharge pusher. The discharge pusher is connected to the piston rod of the discharge-driven cylinder. The CNC milling mechanism, several fixture table drive cylinders, the discharge-driven cylinder, and several fixture plate drive cylinders are all electrically connected via a PLC controller. After the eyeglasses sheet material is bonded to the adhesive board and cut, it is placed along the feeding conveyor belt onto the secondary feeding limit rod group and falls onto the pusher fixture plate. At this time, the fixture plate drive cylinder starts to move the pusher fixture plate away, and the eyeglasses sheet material falls onto the movable fixture table. Then, the fixture plate drive cylinder starts again. The pusher clamp plate is reset, during which the plate block is disengaged from the bottom of the secondary feed limit rod group and moves forward along the movable clamping table until one end of the plate block contacts the clamping stop, thus clamping the plate block. Then, the clamping table drive cylinder is activated to move the clamped plate block to the bottom of the CNC milling mechanism for engraving the temple. After the temple is engraved, the pusher clamp plate is released, and the discharge drive cylinder is activated to control the discharge pusher block to push the plate block off the movable clamping table and onto the discharge plate, thus completing the process of engraving the temple from the eyeglass plate block.

[0009] A further feature of the present invention is that the ends of both the pusher plate and the pusher clamp plate are provided with chamfered edges to facilitate pushing.

[0010] By adopting the above technical solution, since the ends of the pusher plate and the pusher clamp plate are both provided with chamfered corners to facilitate pushing, collisions between the pusher plate and the pusher clamp plate and the plate above the bottommost plate can be avoided, ensuring that the plate can be pushed out smoothly.

[0011] A further feature of the present invention is that a lifting block is provided at the bottom of the movable fixture table, the lifting block is connected to the piston rods of several fixture table drive cylinders, and several chip removal grooves are formed on the table surface near the clamping edge of the movable fixture table. By adopting the above technical solution, since a lifting block is provided at the bottom of the movable fixture table, the lifting block is connected to the piston rods of several fixture table drive cylinders, and several chip removal grooves are formed on the table surface near the clamping edge of the movable fixture table, the accumulation of milling chips on the fixture table can be avoided, which would affect the clamping firmness.

The lifting frame is arranged above the pair of limiting baffles, and the feeding limiting rod group is arranged on the lifting frame. The feeding limiting rod group is positioned above the pair of limiting baffles. A through-hole 14, matching the shape and size of the eyeglass plate block, is provided near the connection point with the lifting frame. The through-hole is located between a pair of limiting baffles. The shape and size of the pusher plate match the through-hole. The pusher cylinder is fixedly mounted on the lifting frame and aligned with the through-hole. One end of the pusher plate is connected to the piston rod of the pusher cylinder. The cutting mechanism includes a mounting frame 15, a drive cylinder 16, and a cutting blade 17 with a mounting rod. The mounting frame is fixedly mounted on the adjacent end tables of a pair of feeding conveyors. The drive cylinder is fixedly mounted on the top of the mounting frame. The mounting rod of the cutting blade is fixedly connected to the piston rod of the drive cylinder. The position of the cutting blade is aligned with the midpoint of the pair of feeding conveyors, and the blade direction is perpendicular to the running direction of the feeding conveyors. The pair of feeding conveyors, the pusher cylinder, and the drive cylinder are all electrically connected via a PLC controller.

[0020] Before the eyeglasses acetate blocks are CNC machined into temples, an adhesive plate is first attached to one side of the block. This ensures that even if no connection points are left during temple carving, the adhesive plate will prevent the carved temples from falling off. After carving all the temples on a block, the temples are manually removed from the adhesive plate. The system includes a feeding device with a pair of feed conveyors for placing the adhesive plate, a pair of limit baffles, an automatic unloading mechanism for placing and dropping the eyeglasses acetate blocks onto the adhesive plate, and a cutting mechanism. The eyeglasses acetate blocks are batch-loaded onto the automatic unloading mechanism, and then the adhesive plate is placed on the feed conveyors. The conveyors are set to pause after moving a given displacement distance. When the adhesive plate moves on the feed conveyor to… When the automatic unloading mechanism is in operation, the pusher cylinder starts to control the pusher plate to push the plate blocks stacked on the limit rod group down from the lifting frame one by one and land on the adhesive plate located between a pair of limit baffles. Then the conveyor belt starts again and moves a given displacement distance. This process is repeated, and the plate blocks move on the conveyor belt together with the adhesive plate. When the two eyeglass plate blocks on the adhesive plate move between a pair of feeding conveyor belts, the drive cylinder of the cutting mechanism starts to control the cutting blade to press down and cut the adhesive plate between the adjacent pair of eyeglass plate blocks, completing the adhesive plate pasting work on a single eyeglass plate block. Afterwards, the plate block with the adhesive plate is conveyed to the CNC machining device along the feeding conveyor belt and the loading conveyor belt, where the temples can be CNC machined, eliminating the grinding process of the temple connection point.

[0021] An auxiliary cutting module 18 is provided on the mounting rod of the cutting blade. The auxiliary cutting module includes a pressing cylinder 19, a connecting block 20, and a pair of tension springs 21. The pressing cylinder has a through hole that matches the mounting rod. On both sides of the through hole, there are mounting cylinders 22 for mounting the tension springs.

The pressing cylinder is sleeved on the mounting rod through the through hole. The two ends of the pair of tension springs are respectively connected to the pair of mounting cylinders and the connecting block.

[0022] Because the cutting blade mounting rod is equipped with an auxiliary cutting module, the auxiliary cutting module includes a pressing cylinder, a connecting block, and a pair of tension springs. The pressing cylinder has a through hole that matches the mounting rod, and mounting cylinders for mounting the tension springs are provided on both sides of the through hole. A pair of auxiliary pressure plates are symmetrically provided at the bottom of the pressing cylinder. The connecting block is fixedly set on the mounting rod. The pressing cylinder is sleeved on the mounting rod through the through hole. The two ends of the pair of tension springs are respectively connected to the pair of mounting cylinders and the connecting block. When the driving cylinder controls the cutting blade to press down for cutting, the pressing cylinder first contacts and presses down the surfaces of the two eyeglasses sheet blocks located on the pair of conveyor belts. Then the cutting blade falls. During the period when the pressing cylinder presses down on the falling cutting blade, the downward pressure of the pressing cylinder increases due to the action of the tension springs, ensuring that the two eyeglasses sheet blocks located on the pair of conveyor belts will not move when the cutting blade cuts the adhesive board, further ensuring the smooth progress of the cutting work.

[0023] The CNC machining device includes a CNC milling mechanism 24, a mounting base 25, a feeding plate 26, a feeding mechanism 27, and an automatic feeding and clamping mechanism 28 for feeding the assembly of eyeglass plates and adhesive plates.

The material pusher clamp plate and several clamping table drive cylinders are all mounted on the movable clamping table. One end of the material pusher clamp plate is connected to the piston rod of several clamping table drive cylinders. The secondary lifting frame is mounted on the mounting base and located above the movable clamping table and the material pusher clamp plate.

The CNC milling mechanism, several fixture table drive cylinders, the discharge drive cylinder, and several fixture plate drive cylinders are all electrically connected via a PLC controller. After the eyeglasses plate material is bonded to the adhesive board and cut, it is placed along the feeding conveyor belt onto the secondary feeding limit rod group and falls onto the pusher fixture plate along the secondary feeding limit rod group. At this time, the fixture plate drive cylinder starts to move the pusher fixture plate away, and the eyeglasses plate material falls onto the movable fixture table. Then, the fixture plate drive cylinder starts again to... The pusher clamp plate resets, during which the plate block is disengaged from the bottom of the secondary feed limit rod group and moves forward along the movable clamping table until one end of the plate block contacts the clamping stop, thus clamping the plate block. Then, the clamping table drive cylinder is activated to move the clamped plate block to the bottom of the CNC milling mechanism for engraving the temple. After the temple is engraved, the pusher clamp plate is released, and the discharge drive cylinder is activated to control the discharge pusher block to push the plate block off the movable clamping table and onto the discharge plate, completing the process of engraving the temple from the eyeglass plate block.

[0025] Both the pusher plate and the pusher clamp plate have beveled edges at their ends to facilitate pushing.

[0026] Since the ends of the pusher plate and the pusher clamp plate are chamfered to facilitate pushing, collisions between the pusher plate and the pusher clamp plate and the plate above the bottommost plate can be avoided, ensuring that the plate can be pushed out smoothly.

[0027] The bottom of the movable fixture table is provided with a lifting block 38, which is connected to the piston rods of several fixture table drive cylinders.
