Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, specifically to a drilling and milling device for eyeglass pads. Background Technology

[0002] The nose pads, also known as nose bridges, are the supporting components of eyeglasses that sit on the bridge of the nose. There are two types of nose pads: fixed (non-metallic, adhesive) and movable. (See also...) Figure 1 As shown, the movable nose pad 10 includes a support portion 101 and a blade portion 102. The support portion 101 is the part that connects to the frame, and the blade portion 102 is the part that contacts the bridge of the nose. To ensure a better connection between the support portion 101 and the frame, the support portion 101 needs to be drilled and milled on both sides; therefore, an automatic nose pad drilling and milling machine is used for processing. Existing automatic nose pad drilling and milling machines use a robotic arm to load the nose pads to the processing station, where a drilling and milling device next to the station performs the drilling and milling. In this loading method, the nose pads must be neatly arranged on a tray, and the tray must be placed within the robotic arm's working area. This results in a large space occupied by tray-loaded nose pads and requires manual placement of the trays, which is not conducive to the miniaturization of the drilling and milling equipment. Summary of the Invention

[0003] The purpose of this utility model is to provide a drilling and milling device for eyeglass pads, so as to solve the problem that the existing drilling and milling devices use robotic arms for loading, resulting in a large space occupation during loading, which is conducive to the miniaturization of the equipment.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a drilling and milling device for eyeglass pads, including a vibratory feeder, a suction cup mechanism, a material transfer mechanism, and a drilling and milling station. The vibratory feeder is used to sequentially transport the pads to a temporary storage position. The temporary storage position is provided with a groove for accommodating the support portion of the pads so that the pads are transported to the temporary storage position with the blade portion facing upwards and the support portion facing downwards. The suction cup mechanism is disposed above the temporary storage position to adsorb the blade portion of the pads and rotate the pads so that their support portion faces upwards. The material transfer mechanism is used to move the pads from the suction cup mechanism to the drilling and milling station to realize the loading of the pads.

[0005] In one embodiment, the suction cup mechanism includes a rotary cylinder, a suction cylinder, and a suction cup. The suction cup is positioned directly above the temporary storage position and has an adsorption groove corresponding to the shape of the blade portion. The suction cup is connected to a negative pressure device to draw the blade portion of the leaf into the adsorption groove using negative pressure. The body of the suction cylinder is connected to the rotary output end of the rotary cylinder, and the telescopic part of the suction cylinder is connected to the suction cup. Thus, the suction cup rises and falls under the driving action of the suction cylinder to draw the leaf. The rotary cylinder drives the suction cylinder and the suction cup to rotate so that the leaf adsorbed on the suction cup is rotated so that the support portion faces upward.

[0006] In one embodiment, the temporary storage position is provided with a channel connected to the output end of the vibratory feeder, and the end of the channel away from the vibratory feeder is a constricted structure, which forms a movement limit for the blade, and the groove of the temporary storage position is disposed in the middle of the bottom surface of the channel.

[0007] In one embodiment, the material transfer mechanism includes a lateral movement component, a loading component, and a unloading component. The lateral movement component includes a lateral movement drive and a connecting plate. The connecting plate is driven to the lateral movement drive and reciprocates laterally in the left-right direction under the driving action of the lateral movement drive. The loading component and the unloading component are spaced apart on the connecting plate in the left-right direction and move laterally left and right synchronously. The loading component is used to move the support leaf from the suction cup mechanism to the drilling and milling station to realize the loading of the support leaf. Along the left-right direction, a unloading channel is provided on one side of the temporary storage position. The unloading component is used to move the support leaf from the drilling and milling station to the unloading channel to realize the unloading of the support leaf.

[0008] In one embodiment, the feeding assembly includes a feeding lifting cylinder, the telescopic part of which is connected to a feeding clamping cylinder in a driving relationship. Two feeding jaws are arranged opposite to each other and are respectively connected to the feeding clamping cylinder. Thus, the feeding lifting cylinder drives the feeding clamping cylinder and the two feeding jaws to rise and fall. Under the action of the feeding clamping cylinder, the two feeding jaws selectively open or close to clamp or release the support pile of the support leaf.

[0009] In one embodiment, the drilling and milling station is connected to a station adjustment structure, which is used to move the drilling and milling station in the front-back direction. A feeding adjustment structure is also provided between the telescopic part of the feeding lifting cylinder and the feeding clamping cylinder. The feeding adjustment structure is used to adjust the position of the feeding jaw on the plane formed in the up-down and left-right directions. The feeding adjustment structure and the station adjustment structure cooperate to make the feeding jaw correspond to the drilling and milling station.

[0010] In one embodiment, the feeding adjustment structure includes a feeding adjustment motor connected to the telescopic part of the feeding lifting cylinder. The output end of the feeding adjustment motor is connected to a belt pulley transmission mechanism. The output end of the belt pulley transmission mechanism is connected to the feeding clamping cylinder. The feeding adjustment motor is used to drive the feeding jaw to rotate, thereby the feeding adjustment motor and the transverse drive component cooperate to adjust the position of the feeding jaw on the plane formed in the up, down, left, and right directions.

[0011] In one embodiment, a buffer and shock-absorbing structure is provided between the output end of the belt pulley transmission mechanism and the loading clamping cylinder. The buffer and shock-absorbing structure includes springs extending vertically to buffer the vibration caused to the loading clamping claw during the movement of the material transfer mechanism.

[0012] In one embodiment, the feeding assembly includes a feeding lifting cylinder, the telescopic part of which is connected to a feeding clamping cylinder, and two feeding jaws are arranged opposite to each other and respectively connected to the feeding clamping cylinder. Thus, the feeding lifting cylinder drives the feeding clamping cylinder and the two feeding jaws to rise and fall. Under the action of the feeding clamping cylinder, the two feeding jaws selectively open or close to clamp or release the support pile of the support leaf.

[0013] The beneficial effects of this utility model are: This utility model uses a vibratory plate, a suction cup and a material transfer mechanism to transport the trays to the drilling and milling station in sequence to realize the feeding of the trays. The vibratory plate feeding method can put a large number of trays into the vibratory plate at one time, without the need to place the trays side by side, reducing the space occupied by the trays when preparing for feeding. In addition, the vibratory plate has a small footprint, further reducing the space occupied by feeding. Attached Figure Description

Detailed Implementation

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] See Figures 2 to 4 As shown, this utility model discloses a drilling and milling device for eyeglass pads, including a vibratory feeder 1, a suction cup mechanism 2, a material transfer mechanism Y, and a drilling and milling station 3. The structure of the pad 10 is shown in the attached diagram. Figure 1 As shown, the nose pad 10 includes a support portion 101 and a blade portion 102. The support portion 101 is the part that connects to the frame, and the blade portion 102 is the part that contacts the bridge of the nose. This drilling and milling equipment is used to drill holes in the support portion 101 and mill grooves on both sides of the support portion 101 to facilitate the connection of the nose pad to the frame.

[0028] See Figures 2 to 5As shown, the vibratory feeder 1, suction cup mechanism 2, and drilling and milling station 3 are arranged sequentially from right to left. The vibratory feeder 1 is used to transport the leaf 10 sequentially to the temporary storage station 4. The temporary storage station 4 is provided with a groove 41 for accommodating the support portion 101 of the leaf so that the leaf is transported to the temporary storage station 4 with the blade portion 102 facing up and the support portion 101 facing down. The suction cup mechanism 2 is set above the temporary storage station 5 to adsorb the blade portion 102 of the leaf 10 and rotate the leaf 10 so that its support portion 101 faces up. The material transfer mechanism Y is used to move the leaf 10 from the suction cup mechanism 2 to the drilling and milling station 3 to realize the loading of the leaf 10.

[0029] This invention utilizes a vibratory feeder 1 for feeding, requiring only a large number of trays 10 to be placed inside the vibratory feeder 1 at once. Compared to the prior art that uses a robotic arm to grip the trays from the pallet, the vibratory feeder 1 eliminates the need to place the trays and pallets side by side, simplifying the manual feeding operation and reducing the space occupied before feeding the trays. Furthermore, through the cooperation of the vibratory feeder 1, the suction cup mechanism 2, and the material transfer mechanism Y, the trays are sequentially transported to the drilling and milling station, thus achieving the feeding of the trays.

[0030] The structure of the support leaf 10 is such that the support portion 101 is located in the middle of one side surface of the blade portion 102. The height and thickness of the support portion 101 are both greater than the thickness of the blade portion 102, especially the height of the support portion 101 is much greater than the thickness of the blade portion 102, while the length and width of the blade portion 102 are much greater than the support portion 101. The center of gravity of the support leaf 10 is located near the blade portion 102 on the support portion 101. When using a vibratory feeder 1 for feeding, the support leaf 10 experiences slight vibration. If a clamp is used to pick up the support portion 101 of the support leaf 10, it will be difficult to accurately pick up the support leaf 10 due to the vibration, which is not conducive to smooth feeding. This utility model sets up a suction cup mechanism 2 to pick up the support leaf. Since the suction cup mechanism 2 adsorbs the support leaf through a large-area suction, it has a large tolerance, and the slight vibration of the support leaf 10 will not affect the reliability of its adsorption. In addition, the support leaf 10 after being adsorbed by the suction cup mechanism 2 is more stable, which is beneficial for the clamp to pick up the support portion 101. In this embodiment, the vibratory feeder 1 transports the leaf 10 with the blade portion 102 facing upwards and the support portion 101 facing downwards to the temporary storage position 4. Therefore, the vibratory feeder 1 involves a screening process during the vibratory feeding process. The screening process of the vibratory feeder 1 is not the subject of this utility model. It is only required that the vibratory feeder 1 can output the leaf 10 with the blade portion 102 facing upwards and the support portion 101 facing downwards. However, it is foreseeable that the output end of the vibratory feeder 1 is also provided with a groove to accommodate the support portion 101, and this groove corresponds to the groove 41 on the temporary storage position 4. The groove 41 on the temporary storage position 4 can provide a receiving space for the support portion 101 so that the blade portion 102 faces directly upwards, which is beneficial for the suction cup mechanism 2 to pick up the leaf 10. It can also make the support portion 101 face upwards after the suction cup mechanism 2 rotates the leaf 10, so that the material transfer mechanism Y can clamp the support portion 101 to move the leaf 10.

[0031] See Figures 6 to 7 As shown, the suction cup mechanism 2 includes a rotary cylinder 21, a suction cylinder 22, and a suction cup 23. The suction cup 23 is positioned directly above the temporary storage position 4. The suction cup 23 has an adsorption groove 231 corresponding to the shape of the blade portion 102. The suction cup 23 is connected to a negative pressure device to use negative pressure to suck the blade portion 102 of the support leaf 10 into the adsorption groove 231. Because the suction cup 23 has a large adsorption surface and a large tolerance space, its limiting function for the support leaf 10 is relatively poor. The presence of the adsorption groove 231 can limit the blade portion 102, so that the material transfer mechanism Y can more accurately clamp the support portion 101. The body of the suction cylinder 22 is connected to the rotary output end of the rotary cylinder 21. The telescopic part of the suction cylinder 22 is connected to the suction cup 23. Thus, the suction cup 23 rises and falls under the driving action of the suction cylinder 22 to pick up the leaf 10. The rotary cylinder 21 is used to drive the suction cylinder 22 and the suction cup 23 to rotate so that the leaf adsorbed on the suction cup 23 is rotated to the upward position of the support pile 101, so that the material transfer mechanism Y can clamp the support pile 101.

[0032] See Figure 5 As shown, the temporary storage position 4 is provided with a channel 42 connected to the output end 11 of the vibratory plate 1, and the end of the channel 42 away from the vibratory plate 1 is a constricted structure. The constricted structure forms a movement limit for the leaf 10, preventing the leaf 10 from moving forward continuously under the action of the vibratory plate 1 until it exceeds the position that the suction cup 23 can pick up. It can also prevent the suction cup 23 from picking up too many leaves 10 at once. The groove 41 of the temporary storage position 4 is provided in the middle of the bottom surface of the channel 42.

[0033] See Figures 2 to 4 , Figure 8 As shown, the material transfer mechanism Y includes a transverse component 5, a loading component 6, and a unloading component 7. The transverse component 5 includes a transverse drive component 51 and a connecting plate 52. In this embodiment, the transverse drive component 51 is a linear motor module, but in other embodiments, it can also be a cylinder. The connecting plate 52 is driven and connected to the linear motor module, and reciprocates transversely in the left-right direction under the driving action of the linear motor module. The loading component 6 and the unloading component 7 are spaced apart on the connecting plate 52 in the left-right direction, so that the loading component 6 and the unloading component 7 move synchronously left and right with the connecting plate 52 under the driving action of the linear motor module. The loading component 6 is used to move the tray 10 from the suction cup mechanism 2 to the drilling and milling station 3 to realize the loading of the tray 10. Along the left-right direction, a unloading channel 8 is provided on one side of the temporary storage position 4. The unloading component 7 is used to move the tray 10 from the drilling and milling station 3 to the unloading channel 8 to realize the unloading of the tray 10. A receiving box 80 is provided below the unloading channel 8 to receive and collect the drilled and milled support leaf 10 that falls from the unloading channel 8.

[0034] The feeding assembly 6 includes a feeding lifting cylinder 61. The telescopic part of the feeding lifting cylinder 61 is connected to a feeding clamping cylinder 62. Two feeding claws 63 are arranged opposite to each other and are respectively connected to the feeding clamping cylinder 62. Thus, the feeding lifting cylinder 61 drives the feeding clamping cylinder 62 and the two feeding claws 63 to rise and fall. Under the action of the feeding clamping cylinder 62, the two feeding claws 63 selectively open or close to clamp or release the support pile part 101 of the support leaf.

[0035] See Figures 2 to 3 , Figures 8 to 10 As shown, the milling station 3 is connected to a station adjustment mechanism 9, which is used to move the milling station 3 in the front-to-back direction. A feeding adjustment structure is also provided between the telescopic part of the feeding lifting cylinder 61 and the feeding clamping cylinder 62. The feeding adjustment structure includes a feeding adjustment motor 64 connected to the telescopic part of the feeding lifting cylinder 61. The output end of the feeding adjustment motor 64 is connected to a belt pulley transmission mechanism 65. The output end of the belt pulley transmission mechanism 65 is connected to the feeding clamping cylinder 65. The feeding adjustment motor 64 is used to drive the feeding gripper 63 to rotate. Thus, the feeding adjustment motor 64 and the transverse drive component 51 cooperate to adjust the position of the feeding gripper 63 on the plane formed in the up-down and left-right directions. The feeding adjustment structure and the station adjustment mechanism 9 cooperate to make the feeding gripper 63 correspond to the milling station 4, thereby improving the accuracy of feeding.

[0036] The station adjustment mechanism 9 is a linear motor module. The linear motor module drives the drilling and milling station 3 to move back and forth.

[0037] A buffer and shock-absorbing structure is provided between the output end of the belt pulley drive mechanism 65 and the loading clamping cylinder 62. The buffer and shock-absorbing structure includes a spring 66 extending vertically to buffer the vibration caused to the loading clamp 63 during the movement of the transfer mechanism Y. The loading clamping cylinder 62 is connected to the output end of the belt pulley drive mechanism 65 through a connecting block 67 and a lifting slide rail slider assembly 68. The output end of the belt pulley drive mechanism 65 is connected to a fixed block 69. The spring 66 is disposed between the connecting block 67 and the fixed block 69. As the spring 66 extends and retracts, the slide rail and slider of the lifting slide rail slider assembly 68 slide relative to each other, thereby driving the loading clamping cylinder 62 and the loading clamp 63 to rise and fall, thus playing a shock-absorbing role and preventing the loading clamp 63 from vibrating undesirably due to the movement of the transfer mechanism Y.

[0038] The unloading assembly 7 includes an unloading lifting cylinder 71. The telescopic part of the unloading lifting cylinder 71 is connected to an unloading clamping cylinder 72. Two unloading claws 73 are arranged opposite to each other and are respectively connected to the unloading clamping cylinder 72. Thus, the unloading lifting cylinder 71 drives the unloading clamping cylinder 72 and the two unloading claws 73 to rise and fall. Under the action of the unloading clamping cylinder 73, the two unloading claws 73 selectively open or close to clamp or release the support pile part 101 of the support leaf 10.

[0039] The loading clamping cylinder 62 and the unloading clamping cylinder 72 are finger cylinders. The loading claw 63 and the unloading claw 73 correspond to one finger of the corresponding finger cylinder. The opening and closing of the loading claw 63 and the unloading claw 73 are achieved by opening and closing the two fingers of the finger cylinder.

[0040] In this embodiment, the unloading component 7 is located on the right side of the loading component 6, and the unloading channel 8 is located on the right side of the temporary storage position 4. The distance between the loading gripper 63 and the unloading gripper 73 is equal to the distance between the temporary storage position 4 and the unloading channel 8, so that the loading component 6 and the unloading component 6 can operate simultaneously to perform loading and unloading at the same time.

[0041] The workflow of this utility model is as follows:

[0042] The operator places multiple leaf holders 10 on the vibratory feeder 1. The vibratory feeder 1 vibrates, outputting the leaf holders 10 sequentially to the output end. The leaf holders 10 gradually enter the temporary storage position 4, with the leaf blades 102 facing upwards and the support base 101 facing downwards. The suction cup 23 of the suction cup mechanism 2 faces downwards, and its suction groove 231 has negative pressure suction. Under the action of the suction cylinder 22, the suction cup 23 descends until it picks up the leaf holder 10. The rotation cylinder 21 drives the suction cylinder 22 and the suction cup 23 to rotate 180° so that the support base 101 of the leaf holder 10 faces upwards.

[0043] The Y-action of the material transfer mechanism causes the loading component 6 and the unloading component 7 to move synchronously to the right, and the loading gripper 63 of the loading component 6 moves to directly above the support post 101 of the support leaf 10 on the temporary storage position 4. The loading lifting cylinder 61 moves to lower the loading clamping cylinder 62 and the loading gripper 63. The loading clamping cylinder 62 drives the loading gripper 63 to close to clamp the support post 101. The loading lifting cylinder 61 moves again to raise the loading clamping cylinder 62 and the loading gripper 63.

[0044] The Y-action of the material transfer mechanism causes the loading component 6 and the unloading component 7 to move synchronously to the left. At this time, there are two scenarios: whether there is a completed milling leaf 10 at the drilling and milling station 3. If there is a completed milling leaf 10 at the drilling and milling station 3, the unloading component 7 first picks up the completed milling leaf 10 at the drilling and milling station 3 to clear the drilling and milling station 3, and then the loading component 6 places the un-milled leaf 10 on the drilling and milling station 3. If there is no completed milling leaf 10 at the drilling and milling station 3, the unloading component 7 does not need to clear the drilling and milling station 3, and the loading component 6 directly places the un-milled leaf 10 on the drilling and milling station 3.

[0045] The process of the unloading assembly 7 clamping the support leaf 10 that has been drilled and milled on the drilling and milling station 3 is as follows: the material transfer mechanism Y moves the unloading jaw 73 of the unloading assembly 7 to directly above the support pile 101 of the support leaf 10 on the drilling and milling station 3. The unloading lifting cylinder 71 moves to lower the unloading clamping cylinder 72 and the unloading jaw 73. The unloading clamping cylinder 72 drives the unloading jaw 73 to close to clamp the support pile 101. The unloading lifting cylinder 71 moves again to raise the unloading clamping cylinder 72 and the unloading jaw 73.

[0046] The process of the feeding assembly 6 placing the un-drilled and milled support leaf 10 on the drilling and milling station 3 is as follows: the material transfer mechanism Y moves the feeding gripper 63 of the feeding assembly 6 to directly above the drilling and milling station 3, the feeding lifting cylinder 61 moves the feeding clamping cylinder 62 and the feeding gripper 63 to descend, the feeding clamping cylinder 62 drives the feeding gripper 63 to open to release the support pile 101 and place the support leaf 10 on the drilling and milling station 3, the feeding lifting cylinder 61 moves again to raise the feeding clamping cylinder 62 and the feeding gripper 63, thus completing the feeding of the support leaf 10.

[0047] The material transfer mechanism Y operates again, positioning the material feeding gripper 73 of the material feeding assembly 7 directly above the material feeding channel 8. The material feeding lifting cylinder 71 operates, causing the material feeding clamping cylinder 72 and the material feeding gripper 73 to descend. The material feeding clamping cylinder 72 drives the material feeding gripper 73 to open and release the support pile 101. The support leaf 10 falls into the material feeding channel 8. The lifting cylinder 71 operates again, causing the material feeding clamping cylinder 72 and the material feeding gripper 73 to rise, thus completing the material feeding of the support leaf 10.

[0048] In this embodiment, by setting the loading component 6 and the unloading component 7 on the connecting plate 52 and moving them horizontally in sync, the structure of the horizontal movement component can be simplified. Only one horizontal movement drive is needed to drive the loading component 6 and the unloading component 7 to move horizontally. On the other hand, the loading component 6 and the unloading component 7 cooperate to be used for loading and unloading respectively. The two loading jaws 63 and the two unloading jaws 73 form a set of clamps, that is, the two sets of clamps are used for loading and unloading respectively. Compared with using the same set of clamps for loading and unloading, the number of times the clamps move back and forth during loading and unloading can be reduced, thereby improving the efficiency of loading and unloading, and thus improving the processing efficiency of the drilling and milling equipment.

[0049] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
