All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the scope of protection of the present disclosure.

In order to improve the positioning accuracy of the complete mold and further improve the accuracy of the cutting tool in cutting the complete mold, the embodiment of the disclosure provides a mold sorting machine for contact lens manufacturing.

As shown in fig. 1 and 2, some embodiments of the present disclosure provide a mold sorter 1 for use in contact lens manufacturing for cutting complete molds 2, the complete molds 2 including a support bar 21, a plurality of punches 23 distributed on the circumferential side of the support bar 21, and a connecting bar 22 connected between each punch 23 and the support bar 21.

As shown in fig. 1, 2, 3, and 4, the mold sorter 1 includes:

a frame 11.

A positioning and cutting mechanism 12 comprising: the die comprises a spring 121 which is arranged on the rack 11 and stretches out and draws back along the height direction, a bearing panel 122 which is fixed at one end of the spring 121 far away from the rack 11, a plurality of positioning cones 123 which are fixed on the bearing panel 122, and a plurality of cutting tools 124 which are connected with the rack 11 and arranged around the edge of the bearing panel 122, wherein the bearing panel 122 is used for bearing the complete die 2 and is provided with a cutting groove, the positioning cones 123 are circularly arranged around the center of the bearing panel 122 so that each connecting rod 22 is positioned between every two positioning cones 123 to position the complete die, and the cutting tools 124 are used for cutting the complete die through the cutting groove 1221 when the spring 121 is in a compressed state so as to separate the connecting rod 22 from the male dies 23.

A transfer mechanism 13, comprising: a vertical transfer driving device 131 disposed on the frame 11, and a pressing head fixed to the bottom of the vertical transfer driving device 131, wherein the vertical transfer driving device 131 is configured to push the pressing head 132 to move toward the bearing panel 122, so that the bearing panel 122 compresses the spring 121.

The sorting mechanism 14 is fixed to the frame 11 and includes a transfer device 141 and a material receiving device 142, and the transfer device 141 is used for transferring the male mold 23 separated from the connecting rod 22 to the material receiving device 142.

In the embodiments of the present disclosure, the description of "above", "below", "bottom", etc. with respect to the orientation is with respect to the general use state of the mold sorting machine 1. "fixed connection" between two members may be either a direct connection or an indirect connection via other intervening members.

In the embodiment of the present disclosure, as shown in fig. 1 and 2, the frame 11 may be a frame structure, and a specific structure may be formed by connecting a plurality of section steels 112 through bolts, and the cross-sectional area of the section steels 112 may be rectangular or square; and a plurality of rollers 113 and support legs 114 are installed below the bottom section steel 112.

As shown in fig. 5 and 6, the diameter of each positioning cone 123 in the positioning and cutting mechanism 12 gradually increases along the axial direction of the positioning cone 123 from the end far from the bearing panel 122 to the end near the bearing panel 122. In this way, in the process that the complete mold falls onto the bearing panel 122 from above the positioning cone 123, the bus bar in the inclined state on the positioning cone 123 can play a good guiding role for the complete mold 2, so that the connecting rod 22 can accurately fall between the positioning cones 123.

A plurality of location cones 123 are circular setting around the center that bears panel 122, have the clearance between per two location cones 123, this clearance can be the same with the diameter of the connecting rod 22 of complete mould 2, or the diameter of connecting rod 22 is big is compared in this clearance, so that clearance fit between two location cones 123 and the connecting rod 22, like this, not only can play the effect of location to complete mould 2, the activity of connecting rod 22 between two location cones 123 has been restricted simultaneously, and then the positioning accuracy to complete mould 2 is improved.

As shown in fig. 5, a plurality of cutting tools 124 may be fixed on the frame 11 and arranged around the edge of the bearing panel 122, since the cutting tools 124 are used for cutting the complete die 2 to separate the punch 23 from the connecting rod 22, and the connecting rod 22 is usually arranged at the circumference of the supporting rod 21, therefore, a plurality of cutting tools 124 may also be arranged on one circumference, and the diameter of the circumference formed by each cutting tool 124 may be arranged with reference to the diameter of the circumference formed by the punch 23, so that the cutting tools 124 can cut the complete die 2 through the cutting groove 1221 when the spring 121 is in a compressed state to separate the connecting rod 22 from the punches 23. It should be noted here that, in order to enable the cutting tool 124 to pass through the cutting groove 1221, the cutting groove 1221 and the cutting tool 124 may correspond one to one, that is, the cutting tool 124 is equal in number to the cutting groove 1221, and the cutting tool 124 is aligned with the cutting groove 1221 in the vertical direction.

In addition, as shown in fig. 5, when the spring 121 is in a relaxed state, the top of the plurality of cutters 124 may not expose the carrier panel 122, so that the complete mold 2 can be smoothly dropped into the carrier panel 122, and accidental injury to workers can also be avoided.

The vertical transfer driving device 131 in the transfer mechanism 13 may be an air cylinder, a cylinder of the air cylinder is disposed on the frame 11, and a compression joint 132 is fixedly connected to the bottom of a telescopic rod of the air cylinder. The telescoping rod of the air cylinder can be used to push the crimp head 132 to move the crimp head 132 toward the load panel 122 to cause the load panel 122 to compress the spring 121.

In the embodiment of the present disclosure, the complete mold 2 is generally lowered from above the positioning cone 123, falls on the bearing panel 122 and is positioned by the plurality of positioning cones 123, the driving end of the vertical transfer driving device 131 pushes the crimping head 132 to move towards the bearing panel 122, and after the crimping head 132 contacts the bearing panel 122, the vertical transfer driving device 131 continues to move towards the bearing panel 122, thereby pushing the bearing panel 122 to compress the spring 121, so that the cutting tool 124 passes through the cutting groove 1221 on the bearing panel 122. Since the complete mold 2 is placed on the bearing panel 122, the cutting knife 124 passing through the cutting groove 1221 can cut the complete mold 2, thereby separating the punch 23 and the connecting bar 22.

In the embodiment of the present disclosure, since the positioning cone 123 in the positioning and cutting mechanism 12 can fix the complete mold 2 well, when the vertical transfer driving device 131 in the transfer mechanism 13 drives the pressing head 132 to move toward the fixed panel, an acting force can be applied to the bearing panel 122 and the elastic member is compressed, so that the cutting tool 124 extends out of the bearing panel 122 and accurately cuts the complete mold 2, thereby separating the punch 23 from the connecting rod 22, and therefore, the embodiment of the present disclosure can improve the positioning accuracy of the complete mold 2, thereby improving the accuracy of the cutting tool 124 in cutting the complete mold 2.

As shown in fig. 9, in some embodiments of the present disclosure, a plurality of grooves 1321 are provided on the crimping head 132 of the transfer mechanism 13, and the plurality of grooves 1321 are arranged in a circle around the center of the crimping head 132, so that after the complete mold 2 is positioned in the plurality of positioning cones 123, the plurality of grooves 1321 correspond to the plurality of punches 23 one by one. Since the complete die 2 is placed on the bearing panel 122 when the complete die 2 is cut, the punch 23 is prevented from being damaged due to the pressing force of the crimping head 132 on the punch 23 when the bearing panel 122 is pushed. A plurality of grooves 1321 may be provided on one end surface of the crimping head 132 facing the carrier panel 122, after the complete mold 2 is positioned in the positioning cones 123, the grooves 1321 correspond to the punches 23 one by one, the width of the grooves 1321 is greater than the diameter of the punches 23, and the depth of the grooves 1321 is greater than the height of the punches 23, so that when the crimping head 132 contacts the carrier panel 122, no pressing force is generated between the crimping head 132 and the punches 23, and damage to the punches 23 is reduced.

In addition, when the cutting blade 124 cuts the complete die 2, the cutting blade 124 may exert a force on the complete die 2 to cause a failure in cutting, or the complete die 2 may be displaced to cause an inaccurate cutting of the complete die 2 by the cutting blade 124. Therefore, in a related art, a plurality of crimping rods 1322 may be disposed on an end surface of the crimping head 132 facing the bearing panel 122, and the plurality of crimping rods 1322 are configured to apply an acting force to the connecting rod 22 of the complete mold 2 in a process of acting between the crimping head 132 and the bearing panel 122, so as to limit a displacement of the complete mold 2 in a vertical direction, and further make the complete mold 2 not easily deviate when bearing a cutting force of the cutting tool 124, thereby further improving accuracy of cutting the complete mold 2 by the cutting tool 124.

As shown in fig. 5, in some embodiments of the present disclosure, positioning the cutting mechanism 12 further comprises:

a vertical positioning driving device 125 fixed on the frame 11, and a fixing member 126 arranged at the driving end of the vertical positioning driving device 125, wherein one end of the spring 121 far away from the bearing panel 122 is fixedly connected with the fixing member 126, and one end of the plurality of cutting tools 124 far away from the bearing panel 122 is fixedly connected with the fixing member 126.

The vertical positioning driving device 125 may be an air cylinder, wherein a cylinder of the air cylinder is fixedly connected to the frame 11, an expansion rod of the air cylinder is fixedly connected to the fixing member 126, and an end of the spring 121 far away from the bearing panel 122 is fixedly connected to the fixing member 126. Since the male mold 23 falls onto the bearing panel 122 after the cutting tool 124 cuts the complete mold 2 and separates the male mold 23 from the connecting rod 22, the vertical positioning driving device 125 can extend and retract by driving the telescopic rod, so that the fixing member 126 drives the bearing panel 122 to move in the vertical direction, and the male mold 23 separated from the connecting rod 22 is conveyed to a designated position.

As shown in fig. 8, in some embodiments of the present disclosure, positioning the cutting mechanism 12 further comprises: and the cylinder barrel of the blocking cylinder 127 is fixed on the rack 11, the telescopic rod of the blocking cylinder is rotatably connected with the fixing piece 126, and the fixing piece 126 is rotatably connected with the driving end of the vertical positioning driving device 125. When the telescopic rod of the blocking cylinder stretches, the telescopic rod drives the fixing member 126 to rotate, so as to drive the cutting tool 124 and the bearing panel 122 to rotate, and the bearing panel 122 drives the complete mold 2 placed thereon to rotate. Before the complete die 2 is cut, when the punch 23 does not correspond to the recess 1321 on the crimping head 132, if the cutting process is directly performed, the complete die 2 may not be cut, or the punch 23 may not be separated from the connecting rod 22 although the complete die 2 can be cut. Therefore, the telescopic rod of the blocking cylinder can be used for stretching, so that the bearing panel 122 can be rotated, the position of the male die 23 can be adjusted to be consistent with the position of the groove 1321, and the cutting accuracy of the cutting tool 124 on the complete die 2 can be further ensured.

As shown in fig. 9, 10 and 11, in some embodiments of the present disclosure, the transfer mechanism 13 further includes:

the horizontal transfer cylinder 133 and the clamping cylinder 134 arranged on the press-connection head 132 are arranged, a cylinder barrel of the horizontal transfer cylinder 133 is fixed on the frame 11, an expansion rod of the horizontal transfer cylinder 133 is fixedly connected with the vertical transfer driving device 131, the vertical transfer driving device 131 is slidably connected with the frame 11, and the clamping cylinder 134 is used for clamping the support rod 21 after the complete die 2 is cut.

The cylinder of the horizontal transfer cylinder 133 is fixed on the frame 11, the vertical transfer driving device 131 is slidably connected with the frame 11, and the telescopic rod of the horizontal transfer cylinder 133 can push the vertical transfer driving device 131 to move along the horizontal direction of the frame 11 through extension and retraction.

As shown in fig. 9, the clamping cylinder 134 is fixed on the pressing joint 132, the clamping cylinder 134 includes two clamping connection plates 1341 which are oppositely arranged and can be close to and away from each other, and the two clamping connection plates 1341 can be close to each other to clamp the supporting rod 21; the two clamping webs may also be spaced apart from each other so that the support bar 21 is not subjected to a clamping force. Therefore, after the cutting tool 124 finishes cutting the complete mold 2, the supporting rod 21 is placed on the bearing panel 122, the supporting rod 21 can be clamped by the clamping cylinder 134, the vertical transfer driving device 131 is pushed by the telescopic rod of the horizontal transfer cylinder 133, the clamping cylinder 134 and the supporting rod 21 are driven to move along the horizontal direction, and the supporting rod 21 is conveyed to the position above the designated position; then the two clamping connecting rods of the clamping cylinder 134 are separated from each other, and the supporting rod 21 loses the clamping force and falls into a designated position. Therefore, in the embodiment of the present disclosure, the supporting rod 21 can be conveyed to a designated position after the male die 23 is separated from the supporting rod 21, so that the manual collecting operation of the supporting rod 21 is avoided, the degree of automation can be improved, and the working strength of workers can be reduced.

As shown in fig. 9, in some embodiments of the present disclosure, the vertical transfer drive 131 is slidably coupled to the frame 11 by a linear bearing 15. The linear bearing 15 generally comprises: a rail 151, and a slider 152 slidably coupled to the rail 151, wherein the rail 151 is fixed to the frame 11, and the slider 152 is fixedly coupled to the vertical transfer driving device 131 through the coupling bracket 135. The sliding connection between the vertical transfer driving device 131 and the frame 11 is realized by the linear bearing 15, so that the whole structure is simple and the sliding friction force is small.

As shown in fig. 5 and 7, in some embodiments of the present disclosure, the transfer device 141, includes: a vertical sorting driving device 1411 fixed on the frame 11, a connecting plate 1412 fixed at a driving end of the vertical sorting driving device 1411, a horizontal sorting driving device 1413 fixed on the connecting plate 1412, and sorting columns 1414 arranged at a driving end of the horizontal sorting driving device 1413, wherein the vertical sorting driving device 1411 is used for pushing the connecting plate 1412 to move so that the connecting plate 1412 pushes the sorting columns 1414 to move in a vertical direction; the horizontal sorting drive 1413 is used to push the sorting cylinders 1414 towards the collector 142.

The vertical sorting driving device 1411 may be an air cylinder, a cylinder barrel of the air cylinder is fixed on the frame 11, and a telescopic rod of the air cylinder is fixedly connected with the connecting plate 1412. The horizontal sorting driving device 1413 can also be an air cylinder, the cylinder barrel of the horizontal sorting driving device is fixed on the connecting plate 1412, and the telescopic rod of the horizontal sorting driving device is fixedly connected with the sorting cylinder 1414. The vertical sorting drive 1411 may push the connecting plate 1412 to move in a vertical direction, and the horizontal sorting drive 1413 may push the sorting columns 1414 to move in a horizontal direction, i.e., toward the material collector 142.

A plurality of sorting columns 1414 are fixedly connected to the connecting plate 1412, and the number of the sorting columns 1414 is the same as that of the cutting grooves 1221 of the bearing panel 122, that is, the number of the sorting columns 1414 is the same as that of the upper molds 23 of the complete mold 2. The end of the sorting cylinder 1414 facing the bearing panel 122 of the positioning and cutting mechanism 12 may be provided with a bearing surface corresponding to the cutting groove 1221 of the bearing panel 122, and the width of the bearing surface is smaller than the width of the cutting groove 1221. When the cutting knife 124 has finished cutting the complete mold 2, the male mold 23 falls on the carrier plate 122, and the vertical positioning drive 125 drives the fixing member 126 to move downward, i.e. toward the sorting cylinder 1414, and when the sorting cylinder 1414 passes through the cutting slot 1221 of the carrier plate 122, the male mold 23 falls on the sorting cylinder 1414. The sorting cylinder 1414 can then be pushed by the horizontal sorting drive 1413 towards the material receiving device 142, thereby transporting the punch 23 onto the material receiving device 142.

The multi-position cylinder can comprise a plurality of cylinder barrels and telescopic rods, and the telescopic rods can have different stroke ranges by enabling liquid in different cylinder barrels to exert pressure. When the male dies 23 need to be placed in the lower layer of the receiving tray 1421, the horizontal sorting driving device 1413 can be used for pushing the sorting cylinder 1414, and the pressure is applied to the cylinder with the smaller diameter in the multi-position air cylinder, so that the sorting cylinder 1414 moves downwards to place the male dies 23 in the layer of the receiving tray 1421; when it is desired to place the punches 23 in the upper tray 1421, pressure is applied to the larger diameter cylinder of the multi-position cylinder to move the sorting cylinder 1414 and the connecting plate 1412 to a position slightly higher than the height of the upper tray 1421, and then the horizontal sorting drive 1413 pushes the sorting cylinder 1414 and applies pressure to the smaller diameter cylinder of the multi-position cylinder to move the sorting cylinder 1414 downward to place the punches 23 in the upper tray 1421. Therefore, by providing the vertical sorting drive device 1411 as a multi-position cylinder, it is possible to place the male molds 23 in the receiving tray 1421 on different heights.

In addition, the controller is also electrically connected with the blocking cylinder and can send a starting signal for the blocking cylinder.

Since the complete mold 2 needs to be dropped on the carrier panel 122 from above the positioning and cutting mechanism 12, the transfer mechanism 13 is not above the positioning and cutting mechanism 12 until the complete mold 2 is dropped on the carrier panel 122. Therefore, when the complete mold 2 passes the sensor, the complete mold 2 falls on the carrier panel 122, the sensor sends a signal to the controller, the controller sends a signal to activate the horizontal transfer cylinder 133 and the blocking cylinder, and when the horizontal transfer cylinder 133 and the blocking cylinder receive the activated signal. The horizontal transfer cylinder 133 pushes the vertical transfer driving device 131 to move towards the positioning cutting mechanism 12 until the press joint 132 is positioned right above the positioning cone 123; meanwhile, the blocking cylinder pushes the fixing plate to rotate, so that the male die 23 corresponds to the position of the groove 1321 on the crimping head 132. Then, the vertical transfer driving means 131 pushes the crimping head 132 to move toward the bearing panel 122, the bearing panel 122 compresses the spring 121, the cutting tool 124 passes through the cutting groove 1221, the complete die 2 is cut, and the punch 23 and the connecting bar 22 are separated.

Then the clamping cylinder 134 clamps the support rod 21, the vertical transfer driving device 131 pushes the press head 132 to move upwards, the horizontal transfer cylinder 133 pushes the vertical transfer driving device 131 to move away from the bearing panel 122, when the vertical transfer driving device moves above the designated position, the horizontal transfer driving device stops moving, and the clamping cylinder 134 releases the clamping force applied to the support rod 21, so that the support rod 21 falls into the designated position.

The vertical positioning driving device 125 pushes the fixed plate to move downwards, when the sorting cylinder 1414 passes through the cutting slot 1221 on the bearing panel 122, the male mold 23 falls on the sorting cylinder 1414, at this time, the horizontal sorting driving device 1413 of the transfer device 141 pushes the sorting cylinder 1414 to move towards the receiving tray 1421, when the sorting cylinder 1414 moves to the discharging groove 1422 on the receiving tray 1421, the vertical sorting driving device 1411 pushes the connecting plate 1412 to move downwards, and the male mold 23 falls on the receiving tray 1421.

The vertical positioning drive 125 of the positioning and cutting mechanism 12 pushes the fixed plate to move upward to its initial position, and the horizontal sorting drive 1413 pushes the sorting cylinder 1414 to move to its initial position.
