[0034] Please refer to Figure 1 , Figure 1 is a schematic diagram of the three-dimensional structure of the ball cutting machine 1100 under one embodiment of the present utility model embodiment. The present utility model embodiment provides a ball cutting machine 1100, which comprises a rod feeding device 1000 and a cutting device 2000. The rod feeding device 1000 is used to feed a plurality of rods to the cutting device 2000, and the cutting device 2000 is used to cut the plurality of rods into spherical bodies respectively.

[0035] Specifically, the rod can be an optical glass round rod. One optical glass round rod can form at least one optical glass ball through the cutting device 2000. The cutting device 2000 processes one rod at a time. After the current rod is close to being processed or has been processed, the rod feeding device sends the next rod to the cutting device 2000. It can be understood that if the rod is jammed, the rod cannot be sent to the cutting device 2000, and manual intervention is required to solve the jamming problem, which causes the processing to be suspended and the processing efficiency to be reduced.

[0036] By adding the rod feeding device 1000 provided by the present utility model embodiment to the ball cutting machine 1100, the risk of rod jamming can be reduced, and the processing efficiency can be improved.

[0037] The cutting device 2000 in the ball cutting machine 1100 provided by the present utility model embodiment is described below.

[0038] Please refer to Figure 1 and Figure 2 , Figure 2 is Figure 1 a schematic diagram of the three-dimensional structure of part of the cutting device 2000 in the ball cutting machine 1100; the cutting device 2000 comprises a base 2100, a first forming mechanism 2200, a second forming mechanism 2300, a limiting mechanism 2400 and a receiving jig 2500. The first forming mechanism 2200, the second forming mechanism 2300, the limiting mechanism 2400 and the receiving jig 2500 are all installed on the base 2100.

[0039] Specifically, the first forming mechanism 2200 comprises a first rotary driver 2210 and a first forming roller 2220. The first rotary driver 2210 is installed on the base 2100 and connected with the first forming roller 2220 to drive the first forming roller 2220 to rotate around its own axis. The first forming roller 2220 is provided with a plurality of annular grooves 22201 extending in the circumferential direction. The inner wall of the annular groove 22201 is arc-shaped to facilitate cutting the bar into a spherical body.

[0040] Specifically, the second forming mechanism 2300 comprises a first translation driver 2310, a second rotary driver 2320, a second forming roller 2330 and a first sensor 2340. The second forming roller 2330 is arranged on the second rotary driver 2320 and can rotate along its own axis under the driving of the second rotary driver 2320. The second rotary driver 2320 is slidingly connected with the base 2100. The first translation driver 2310 is installed on the base 2100 and connected with the second rotary driver 2320 to drive the second rotary driver 2320 to move the second forming roller 2330 relative to the base 2100, so that the second forming roller 2330 approaches or moves away from the first forming roller 2220 to facilitate cutting and forming spherical bodies with different diameters. The first sensor 2340 is arranged on the base 2100 to sense whether the second rotary driver 2320 moves to a preset position relative to the base 2100.

[0041] Specifically, the limiting mechanism 2400 includes a third rotary driver 2410, a rotating plate 2420, a second translation driver 2430, a limiting plate 2440, a second inductor 2450, and a third inductor 2460. The rotating plate 2420 is rotationally connected with the base 2100. The third rotary driver 2410 is installed on the base 2100 and connected with the rotating plate 2420 through a cam structure. Under the driving of the third rotary driver 2410, the cam structure can drive the rotating plate 2420 to repeatedly rise and fall. The second translation driver 2430 is installed on the rotating plate 2420 and connected with the limiting plate 2440. The second translation driver 2430 can drive the limiting plate 2440 to move, so as to adjust the position of the limiting plate 2440 against the bar material, so that the limiting plate 2440 can better resist the bar material and avoid the bar material from jumping out of the processing area between the first forming roller shaft 2220 and the second forming roller shaft 2330. It can be understood that, after the third rotary driver 2410 drives the rotating plate 2420 to rise through the cam structure, space is provided for the bar material to enter the processing area between the first forming roller shaft 2220 and the second forming roller shaft 2330, and after the third rotary driver 2410 drives the rotating plate 2420 to fall through the cam structure, the limiting plate 2440 can resist the bar material to limit the bar material from jumping out of the processing area between the first forming roller shaft 2220 and the second forming roller shaft 2330. During the cutting process, the bar material is clamped by the first forming roller shaft 2220, the second forming roller shaft 2330 and the limiting plate 2440, so as to be unable to leave the processing area and gradually shaped into a sphere under the cutting and polishing of the annular groove 22201 structure. The second inductor 2450 is arranged on the base 2100 and used for sensing whether the rotating plate 2420 is flipped to a preset position relative to the base 2100. The third inductor 2460 is arranged on the rotating plate 2420 and used for sensing whether the limiting plate 2440 is moved to a preset position relative to the rotating plate 2420.

[0042] Specifically, the receiving jig 2500 is arranged on the top side of the second forming roller shaft 2330 and used for receiving the bar material sent by the bar material feeding device 1000 and guiding the bar material to the processing area between the first forming roller shaft 2220 and the second forming roller shaft 2330.

[0043] The bar material feeding device 1000 in the ball cutting machine 1100 provided by the embodiment of the present application is described below.

[0044] Please refer to Figures 3 to 6 , Figure 3 is Figure 1 a perspective structural schematic view of the bar material feeding device 1000 when the stopper 31 of the ball cutting machine 1100 is in the first position; Figure 4 is Figure 3 a perspective structural schematic view of the bar material feeding device 1000 in a cross-sectional state; Figure 5 isFigure 1 a perspective view of the bar loading device 1000 when the stopper 31 is in the second position; Figure 6 is Figure 5 a perspective view of the bar loading device 1000 in a cross-sectional state. The utility model discloses a bar loading device 1000 for ball cutting machine 1100, and the bar loading device 1000 includes base 10, hold down mechanism 20 and stop mechanism 30. Base 10 is used to bear the multiple bar materials arranged in sequence, and the multiple bar materials include adjacent first bar material and second bar material, wherein the first bar material is discharged before the second bar material. Hold down mechanism 20 includes pressing block 21 and first drive 22, and the first drive 22 is arranged on the base 10 and connected with the pressing block 21, so as to drive the pressing block 21 to abut against the second bar material and limit the rolling of the second bar material. Stop mechanism 30 includes stopper 31 and second drive 32, and the stopper 31 is rotationally connected with the base 10, and the second drive 32 is connected with the stopper 31 and can drive the stopper 31 to flip to the first position or the second position relative to the base 10, when the stopper 31 is in the first position, the stopper 31 abuts against the first bar material to limit the rolling of the first bar material, and when the stopper 31 is in the second position, the stopper 31 removes the limitation on the first bar material.

[0045] Specifically, please refer to Figure 1 , the base 10 is installed on the base 2100. The first drive 22 can drive the pressing block 21 to move relative to the base 10 through a gas cylinder, an electric cylinder, a motor or the like, and the movement mode of the pressing block 21 can be selected as one or more of rotation, translation or the like. In the embodiment, the first drive 22 is configured as a gas cylinder to drive the pressing block 21 to translate relative to the base 10. The pressing block 21 can be selected as an elastic block, such as a rubber block, to reduce the risk of the bar material being crushed. The second drive 32 can drive the stopper 31 to flip relative to the base 10 through a gas cylinder, an electric cylinder, a motor or the like. In the embodiment, the second drive 32 is a motor and drives the stopper 31 to rotate through a synchronous belt. Specifically, the first bar material is one closest to the stopper among the multiple bar materials, and the second bar material is the bar material adjacent to the first bar material.

[0046] The bar loading device 1000 provided by the utility model has the following discharge logic:

[0047] When the material is not needed to be discharged, the pressing block 21 is in the first position, the blocking block 31 abuts against the first bar material, and the first bar material is limited from rolling out of the material. At this time, the pressing block 21 can be in a position with a spacing distance from the second bar material, that is, the second bar material is not limited, and since the first bar material is limited from rolling, even if the second bar material is not limited, it will not roll. Alternatively, the pressing block 21 is in a position abutting against the second bar material, that is, the second bar material is limited from rolling. Alternatively, the pressing block 21 is in a position abutting against both the first bar material and the second bar material, that is, both the first bar material and the second bar material are limited from rolling, which is more secure.

[0048] When the material is needed to be discharged, there are various ways, for example:

[0049] The first way is to drive the pressing block 21 to abut against the second bar material by the first driving member 22 to limit the second bar material from rolling, and then drive the blocking block 31 to flip to the second position relative to the base 10 by the second driving member 32, so that the blocking block 31 releases the limitation on the first bar material, and the first bar material can roll out of the material.

[0050] The second way is to drive the blocking block 31 to flip to the second position relative to the base 10 by the second driving member 32, so that the blocking block 31 releases the limitation on the first bar material, and the first bar material can roll. After the first bar material rolls a certain distance (away from the position abutting against the pressing block 21), the pressing block 21 is driven to abut against the second bar material by the first driving member 22 to limit the second bar material from rolling, and at the same time, the first bar material can continue to roll out of the material.

[0051] It should be noted that during the discharging process, the bar material feeding device 1000 sends a bar material to the cutting device 2000 for cutting processing, and the specific discharging method can be selected according to actual needs.

[0052] By arranging the first driving member 22 and the pressing block 21, the first driving member 22 can drive the pressing block 21 to abut against the second bar material to limit the second bar material from rolling, and by arranging the second driving member 32 and the blocking block 31, the second driving member 32 can drive the blocking block 31 to flip from the first position to the second position relative to the base 10 to release the limitation on the first bar material, so that the first bar material can roll out of the material, achieving the discharging of a single bar material. Since there is no need to arrange a limiting groove, the bar material will not encounter any obstruction during the discharging process, the bar material discharges stably, and the bar material is not easy to be stuck, thereby improving the processing efficiency.

[0053] In an embodiment of the embodiment, please refer to Figures 3 to 6The base 10 is provided with a containing groove 101 for containing a plurality of bars. The first driving member 22 can drive the pressing block 21 to approach or move away from the bottom wall of the containing groove 101. In this way, the pressing block 21 can jointly hold the bars with the base 10 to limit the rolling of the bars, and the limiting effect is good.

[0054] In this embodiment, the movement direction of the pressing block 21 is perpendicular to the bottom wall of the containing groove 101, so as to further improve the limiting effect.

[0055] In one embodiment of this embodiment, please refer to Figures 3 to 6 The pressing mechanism 20 includes a mounting plate 23 installed on the base 10 and located on the top side of the containing groove 101. The first driving member 22 is arranged on the mounting plate 23. Specifically, the mounting plate 23 is fixed on the base 10 and located on the top side of the containing groove 101. The first driving member 22 is installed on the mounting plate 23 and connected with the pressing block 21. In this way, the movement of the pressing block 21 relative to the bottom wall of the containing groove 101 can be realized.

[0056] In one embodiment of this embodiment, please refer to Figures 3 to 6 The base 10 is provided with a discharge port 102. The stop block 31 is arranged at the discharge port 102. The discharge port 102 is communicated with the containing groove 101. The bottom wall is inclined relative to the horizontal plane, so that the plurality of bars can roll along the bottom wall to the discharge port 102. Specifically, the stop mechanism 30 is arranged at the discharge port 102 to control the discharge of the bars. The discharge port 102 is communicated with one side of the containing groove 101. It can be understood that by arranging the bottom wall to be inclined relative to the horizontal plane, the plurality of bars can roll along the bottom wall to the discharge port 102 under the action of gravity without the need for additional devices, which is simple in structure and high in efficiency.

[0057] In other embodiments, the bottom wall can also be arranged to be horizontal. An elastic mechanism is arranged at a position in the containing groove 101 away from the discharge port 102. The plurality of bars are driven to roll along the bottom wall to the discharge port 102 by the elastic force provided by the elastic mechanism.

[0058] In one embodiment of this embodiment, please refer to Figures 3 to 7 , Figure 7 is Figure 3 The partial stop mechanism 30 of the bar feeding device 1000 of the bar feeding device 1000 is in an exploded state. The stop mechanism 30 includes a lifting block 33 connected with the stop block 31. When the first driving member 22 drives the stop block 31 to flip from the first position to the second position, the lifting block 33 can lift the first bar to make the first bar roll along the stop block 31. In this way, the first bar can be smoothly discharged from the discharge port 102, and the first bar is not easy to be stuck in the discharge port 102, which improves the processing efficiency.

[0059] In this embodiment, the number of the lifting blocks 33 is multiple, the multiple lifting blocks 33 are arranged in sequence and are fixed to one side of the stop block 31 through the connecting plate 331, so that the stop block 31 and the multiple lifting blocks 33 can be flipped synchronously relative to the base 10.

[0060] In this embodiment, the lifting block 33 is arranged to protrude relative to the two sides of the stop block 31, so that even if the installation direction of the stop block 31 is changed relative to the base 10, the lifting block 33 can still play a role of lifting the bar material.

[0061] In this embodiment, the stop block 31 is provided with a rotating shaft 311, and the two ends of the rotating shaft 311 are rotatably connected to the base 10 through bearings.

[0062] In one embodiment of this embodiment, please refer to Figures 3 to 7 When the stop block 31 is in the second position, the lifting block 33 is opposite to the second bar material to hinder the second bar material from being discharged. It can be understood that since the bar material is made of glass, its surface is relatively smooth, and the second bar material may not be limited by the pressing block 21 and follow the first bar material to be discharged, which affects the processing. In this way, the lifting block 33 can hinder the second bar material from being discharged, and the first bar material can be normally discharged, so as to ensure the normal processing.

[0063] In one embodiment of this embodiment, please refer to Figures 3 to 7 The base 10 is provided with a relief groove 103, and when the stop block 31 is in the first position, the lifting block 33 is arranged in the relief groove 103 and located at the bottom side of the first bar material. Specifically, the number of the relief grooves 103 is the same as the number of the lifting blocks 33, and they are one-to-one corresponding. In this way, the lifting block 33 can lift the first bar material.

[0064] Specifically, please refer to Figure 8 , Figure 8 is Figure 3 the partial base 10 of the bar material loading device 1000, the relief groove 103 is arranged at the position close to the discharge port 102 of the bottom wall of the accommodating groove 101, so as to be opposite to the first bar material, and the lifting block 33 can be away from the relief groove 103 and lift the bar material.

[0065] In one embodiment of this embodiment, please refer to Figure 1 , Figure 5 and Figure 7 The stop mechanism 30 includes a guide rod 34, and the guide rod 34 is connected with the stop block 31. When the stop block 31 is in the second position, the first bar material can roll along the stop block 31 and the guide rod 34 in sequence. In this way, the bar material can roll along the guide rod 34 to the material receiving jig 2500.

[0066] In this embodiment, the number of guide rods 34 is multiple, and the multiple guide rods 34 are arranged on the side of the stopper 31 away from the lifting block 33 to provide sufficient guidance for the bar.

[0067] Please refer to Figures 3 to 6 The utility model discloses a kind of bar feeding methods, and bar feeding method includes:

[0068] S101: multiple bars are placed in base 10;

[0069] S102: by first driving member 22, press block 21 is driven to abut with second bar, to limit the second bar to roll;

[0070] S103: by second driving member 32, stopper 31 is driven to overturn from first position to second position relative to base 10, to remove the restriction to first bar, so that first bar rolls out of material.

[0071] Specifically, step S102 and step S103 can be carried out at different times, or can be carried out simultaneously, based on this, the specific steps of bar feeding have multiple ways, for example:

[0072] way one: first by first driving member 22, press block 21 is driven to abut with second bar, to limit the second bar to roll, then by second driving member 32, stopper 31 is driven to overturn to second position relative to base 10, stopper 31 removes the restriction to first bar, so that first bar can roll out of material.

[0073] way two: first by second driving member 32, stopper 31 is driven to overturn to second position relative to base 10, stopper 31 removes the restriction to first bar, so that first bar can roll.

[0074] By setting first driving member 22, press block 21 can be driven to abut with second bar, to limit the second bar to roll, and by setting second driving member 32, stopper 31 can be driven to overturn from first position to second position relative to base 10, to remove the restriction to first bar, so that first bar can roll out of material, realize the discharge of single bar.

[0075] The utility model embodiment has been explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range of the ordinary skill in the art who possesses under the premise of not departing from the utility model's tenet.
