[0038] See also Figure 1 , Figure 1 1 is a schematic diagram of a three-dimensional structure of a ball cutting machine 1100 according to an embodiment of the present invention. The present invention provides a ball cutting machine 1100, which includes a bar material feeding device 1000 and a cutting device 2000. The bar material feeding device 1000 is used to feed a plurality of bar materials to the cutting device 2000, and the cutting device 2000 is used to cut the plurality of bar materials into spheres respectively.

[0039] Specifically, the bar material may be an optical glass round rod, and one optical glass round rod may be formed into at least one optical glass ball by the cutting device 2000. The cutting device 2000 processes one bar material at a time, and when the current bar material is close to being processed or has been processed, the bar material feeding device feeds the next bar material to the cutting device 2000. It is understandable that if the bar material is stuck and cannot be fed to the cutting device 2000, manual intervention is required to solve the problem of the material jam, which causes the processing to be suspended and the processing efficiency to be reduced.

[0040] By adding the bar material feeding device 1000 provided in the embodiment of the present invention to the ball cutting machine 1100, the risk of material jamming can be reduced and the processing efficiency can be improved.

[0041] The cutting device 2000 in the ball cutting machine 1100 provided in the embodiment of the present invention is described below.

[0042] See also Figure 1 and Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the three-dimensional structure of a part of the cutting device 2000 in the ball cutting machine 1100; the cutting device 2000 includes a base 2100, a first molding mechanism 2200, a second molding mechanism 2300, a limiting mechanism 2400 and a material receiving fixture 2500, and the first molding mechanism 2200, the second molding mechanism 2300, the limiting mechanism 2400 and the material receiving fixture 2500 are all installed on the base 2100.

[0043] Specifically, the first forming mechanism 2200 includes a first rotary driver 2210 and a first forming roller 2220. The first rotary driver 2210 is installed on the base 2100 and connected to 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 circumferentially. The inner wall of the annular groove 22201 is arc-shaped to facilitate cutting of the rod to form a sphere.

[0044] Specifically, the second molding mechanism 2300 includes a first translation driver 2310, a second rotation driver 2320, a second molding roller 2330 and a first sensor 2340. The second molding roller 2330 is arranged on the second rotation driver 2320 and can rotate along its own axis under the drive of the second rotation driver 2320. The second rotation driver 2320 is slidably connected to the base 2100. The first translation driver 2310 is installed on the base 2100 and connected to the second rotation driver 2320 to drive the second rotation driver 2320 to drive the second molding roller 2330 to move relative to the base 2100, so that the second molding roller 2330 approaches or moves away from the first molding roller 2220, so as to facilitate cutting and molding spheres of different diameters. The first sensor 2340 is arranged on the base 2100 and is used to sense whether the second rotation driver 2320 moves to a preset position relative to the base 2100.

[0045] 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 sensor 2450 and a third sensor 2460. The rotating plate 2420 is rotatably connected to the base 2100. The third rotary driver 2410 is mounted on the base 2100 and connected to the rotating plate 2420 through a cam structure. Under the drive of the third rotary driver 2410, the cam structure can drive the rotating plate 2420 to rise and fall repeatedly. The second translation driver 2430 is mounted on the rotating plate 2420 and connected to the limiting plate 2440. The second translation driver 2430 can drive the limiting plate 2440 to move to adjust the position where the limiting plate 2440 abuts against the bar material, so that the limiting plate 2440 can better abut against the bar material to prevent the bar material from jumping out of the processing area between the first forming roller 2220 and the second forming roller 2330. It is understood that after the third rotary driver 2410 drives the rotating plate 2420 to rise through the cam structure, space can be provided to facilitate the bar material to enter the processing area between the first forming roller 2220 and the second forming roller 2330, and after the third rotary driver 2410 drives the rotating plate 2420 to descend through the cam structure, the limiting plate 2440 can be made to abut against the bar material to limit the bar material from jumping out of the processing area between the first forming roller 2220 and the second forming roller 2330. During the cutting process, the bar material is clamped by the first forming roller 2220, the second forming roller 2330 and the limiting plate 2440, so that it cannot leave the processing area, and is gradually formed into a sphere under the cutting and grinding of the annular groove 22201 structure. The second sensor 2450 is arranged on the base 2100, and is used to sense whether the rotating plate 2420 is flipped to a preset position relative to the base 2100. The third sensor 2460 is disposed on the rotating plate 2420 and is used to sense whether the limiting plate 2440 moves to a preset position relative to the rotating plate 2420 .

[0046] Specifically, the material receiving jig 2500 is arranged on the top side of the second forming roller 2330 to receive the bar material sent by the bar material feeding device 1000 and guide it to the processing area between the first forming roller 2220 and the second forming roller 2330 .

[0047] The bar material loading device 1000 in the ball cutting machine 1100 provided in the embodiment of the present invention is described below.

[0048] See also Figures 3 to 6 , Figure 3 yes Figure 1 A schematic diagram of the three-dimensional structure of the bar material feeding device 1000 when the stopper 31 is in the first position; Figure 4 yes Figure 3 A schematic diagram of the three-dimensional structure of the bar material feeding device 1000 in a cross-sectional state; Figure 5 yes Figure 1 A schematic diagram of the three-dimensional structure of the bar material feeding device 1000 when the stopper 31 is in the second position; Figure 6 yes Figure 5 A schematic diagram of the three-dimensional structure of the bar loading device 1000 in a cross-sectional state. An embodiment of the present invention provides a bar loading device 1000 applied to a ball cutting machine 1100, and the bar loading device 1000 includes a base 10, a holding mechanism 20, and a stop mechanism 30. The base 10 is used to carry a plurality of bar materials arranged in sequence, and the plurality of bar materials include adjacent first bar materials and second bar materials, wherein the first bar material is discharged before the second bar material. The holding mechanism 20 includes a pressing block 21 and a first driving member 22, and the first driving member 22 is disposed on the base 10 and connected to the pressing block 21, so as to drive the pressing block 21 to abut against the second bar material to limit the rolling of the second bar material. The stop mechanism 30 includes a stop block 31 and a second driving member 32. The stop block 31 is rotatably connected to the base 10. The second driving member 32 is connected to the stop block 31 and can drive the stop block 31 to flip to a first position or a second position relative to the base 10. When the stop block 31 is in the first position, the stop block 31 abuts against the first rod to limit the rolling of the first rod. When the stop block 31 is in the second position, the stop block 31 releases the restriction on the first rod.

[0049] For details, please refer to Figure 1, the base 10 is installed on the base 2100. The first driving member 22 can drive the pressure block 21 to move relative to the base 10 by means of a cylinder, an electric cylinder, a motor, etc., and the movement mode of the pressure block 21 can be selected as one or more of rotation and translation. In this embodiment, the first driving member 22 is constructed as a cylinder to drive the pressure block 21 to translate relative to the base 10. The pressure block 21 can be selected to have an elastic block, such as a rubber block, to reduce the risk of the bar being crushed. The second driving member 32 can drive the stopper 31 to flip relative to the base 10 by means of a cylinder, an electric cylinder, a motor, etc. In this embodiment, the second driving member 32 is a motor, and drives the stopper 31 to rotate through a synchronous belt. Specifically, the first bar is one of the multiple bars closest to the stopper, and the second bar is a bar adjacent to the first bar.

[0050] The discharge logic of the bar material feeding device 1000 provided in the embodiment of the present invention is:

[0051] When there is no need to discharge the material, the pressing block 21 is in the first position, the stopper 31 abuts against the first bar stock, and the first bar stock is restricted and cannot roll out. At this time, the pressing block 21 can be in a position with a distance from the second bar stock, that is, the second bar stock is not restricted. Since the first bar stock is restricted and cannot roll, even if the second bar stock is not restricted, it will not roll. Alternatively, the pressing block 21 is in a position abutting against the second bar stock, that is, the second bar stock is restricted and cannot roll. Alternatively, the pressing block 21 is in a position abutting against the first bar stock and the second bar stock at the same time, that is, both the first bar stock and the second bar stock are restricted and cannot roll, which is safer.

[0052] When you need to discharge the material, there are many ways, such as:

[0053] Method 1: First, the first driving member 22 drives the pressing block 21 to abut against the second rod material to limit the rolling of the second rod material, and then the second driving member 32 drives the stopper 31 to flip to the second position relative to the base 10. The stopper 31 releases the restriction on the first rod material, so that the first rod material can roll out.

[0054] Method 2: First, the second driving member 32 drives the stopper 31 to flip to the second position relative to the base 10, and the stopper 31 releases the restriction on the first bar material, so that the first bar material can roll. After the first bar material rolls a certain distance (leaving the position where it will be abutted by the pressing block 21), the first driving member 22 drives the pressing block 21 to abut against the second bar material to restrict the rolling of the second bar material. At the same time, the first bar material can continue to roll out.

[0055] It should be noted that, during the discharge process, the bar loading device 1000 delivers a bar to the cutting device 2000 so that the cutting device 2000 can cut the bar. The specific discharge method can be selected according to actual needs.

[0056] By setting the first driving member 22 and the pressure block 21, the first driving member 22 can drive the pressure block 21 to abut against the second rod material to limit the rolling of the second rod material, and by setting the second driving member 32 and the stop block 31, the second driving member 32 can drive the stop block 31 to flip from the first position to the second position relative to the base 10 to release the restriction of the first rod material, so that the first rod material can be rolled out and the discharge of a single rod material is realized. Since there is no need to set a limit groove, the rod material will not encounter obstacles during the discharge process, the discharge of the rod material is stable, and there will be no jamming, thereby improving the processing efficiency.

[0057] In one embodiment of this implementation, please refer to Figures 3 to 6 The base 10 is provided with a receiving groove 101 for receiving a plurality of rods, and the first driving member 22 can drive the pressing block 21 to approach or move away from the bottom wall of the receiving groove 101. In this way, the pressing block 21 can clamp the rod together with the base 10 to limit the rolling of the rod, and the limiting effect is better.

[0058] In this embodiment, the movement direction of the pressing block 21 is perpendicular to the bottom wall of the receiving groove 101 to further enhance the limiting effect.

[0059] In one embodiment of this implementation, please refer to Figures 3 to 6 The pressing mechanism 20 includes a mounting plate 23, which is mounted on the base 10 and located on the top side of the receiving groove 101, and 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 receiving groove 101, and the first driving member 22 is mounted on the mounting plate 23 and connected to the pressing block 21. Such a configuration facilitates the movement of the pressing block 21 relatively close to or away from the bottom wall of the receiving groove 101.

[0060] In one embodiment of this implementation, please refer to Figures 3 to 6 The base 10 is provided with a discharge port 102, a stopper 31 is provided at the discharge port 102, the discharge port 102 is connected to the receiving groove 101, and the bottom wall is inclined relative to the horizontal plane so that a plurality of rods can roll along the bottom wall to the discharge port 102. Specifically, the stopper mechanism 30 is provided at the discharge port 102 to control the discharge of the rods. The discharge port 102 is connected to one side of the receiving groove 101. It can be understood that by setting the bottom wall to be inclined relative to the horizontal plane so that a plurality of rods can roll along the bottom wall to the discharge port 102 under the action of their own weight, no additional device is required, and the structure is simple and efficient.

[0061] In other embodiments, the bottom wall may also be set horizontally, and an elastic mechanism is provided in the accommodating groove 101 at a position away from the discharge port 102, and the elastic force provided by the elastic mechanism is used to drive the multiple rods to roll along the bottom wall close to the discharge port 102.

[0062] In one embodiment of this implementation, please refer to Figures 3 to 7 , Figure 7 yes Figure 3 The three-dimensional structural diagram of the part of the stop mechanism 30 of the bar material feeding device 1000 in the disassembled state. The stop mechanism 30 includes a lifting block 33, which is connected to 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 material so that the first bar material rolls along the stop block 31. Such a configuration can ensure that the first bar material can be discharged smoothly from the discharge port 102, and the first bar material will not be stuck in the discharge port 102, thereby improving the processing efficiency.

[0063] In this embodiment, there are multiple lifting blocks 33, which are arranged in sequence and fixed to one side of the stopper 31 through a connecting plate 331, so that the stopper 31 and the multiple lifting blocks 33 can be flipped synchronously relative to the base 10.

[0064] In this embodiment, the lifting blocks 33 are arranged to protrude on both sides of the stopper 31, so that even after the stopper 31 is replaced in its installation direction with respect to the base 10, the lifting blocks 33 can still play the role of lifting the rod.

[0065] In this embodiment, the stopper 31 is provided with a rotating shaft 311 , and both ends of the rotating shaft 311 are rotatably connected to the base 10 through bearings.

[0066] In one embodiment of this implementation, please refer to Figures 3 to 7 When the stopper 31 is in the second position, the lifting block 33 is opposite to the second bar material to prevent the second bar material from being discharged. It is understandable that since the bar material is made of glass and its surface is relatively smooth, the second bar material may not be restricted by the pressing block 21 and follow the first bar material to be discharged, affecting the processing. In this way, the lifting block 33 can prevent the second bar material from being discharged, and the first bar material can be discharged normally, ensuring normal processing.

[0067] In one embodiment of this implementation, please refer to Figures 3 to 7 The base 10 is provided with an avoidance groove 103. When the stopper 31 is in the first position, the lifting block 33 is arranged in the avoidance groove 103 and is located at the bottom side of the first bar. Specifically, the number of the avoidance grooves 103 is the same as the number of the lifting blocks 33, and they correspond one to one. This arrangement facilitates the lifting block 33 to lift the first bar.

[0068] For details, please refer to Figure 8 , Figure 8 yes Figure 3The schematic diagram of the three-dimensional structure of a part of the base 10 of the rod loading device 1000 is that the avoidance groove 103 is opened at a position close to the discharge port 102 on the bottom wall of the accommodating groove 101 so that the lifting block 33 can leave the avoidance groove 103 and lift the rod relative to the first rod.

[0069] In one embodiment of this implementation, please refer to Figure 1 , Figure 5 and Figure 7 The stop mechanism 30 includes a guide rod 34, which is connected to the stopper 31. When the stopper 31 is in the second position, the first bar can roll along the stopper 31 and the guide rod 34 in sequence. In this way, the bar can roll along the guide rod 34 to the material receiving fixture 2500.

[0070] In this embodiment, there are multiple guide rods 34, and the multiple guide rods 34 are arranged on the side of the stopper 31 facing away from the lifting block 33 to provide sufficient guidance for the bar material.

[0071] See also Figures 3 to 6 The embodiment of the present invention further provides a bar material feeding method, the bar material feeding method comprising:

[0072] S101: placing a plurality of bars on a base 10;

[0073] S102: driving the pressing block 21 to abut against the second bar material through the first driving member 22 to restrict the second bar material from rolling;

[0074] S103: The second driving member 32 drives the stopper 31 to flip from the first position to the second position relative to the base 10 to release the restriction on the first bar material, so that the first bar material rolls out.

[0075] Specifically, step S102 and step S103 can be performed in different time periods or simultaneously. Based on this, there are many specific steps for bar material loading, for example:

[0076] Method 1: First, the first driving member 22 drives the pressing block 21 to abut against the second rod material to limit the rolling of the second rod material, and then the second driving member 32 drives the stopper 31 to flip to the second position relative to the base 10. The stopper 31 releases the restriction on the first rod material, so that the first rod material can roll out.

[0077] Method 2: First, the second driving member 32 drives the stopper 31 to flip to the second position relative to the base 10, and the stopper 31 releases the restriction on the first bar material, so that the first bar material can roll. After the first bar material rolls a certain distance (leaving the position where it will be abutted by the pressing block 21), the first driving member 22 drives the pressing block 21 to abut against the second bar material to restrict the rolling of the second bar material. At the same time, the first bar material can continue to roll out.

[0078] By setting the first driving member 22, the pressure block 21 can be driven to abut against the second rod material to limit the rolling of the second rod material, and the second driving member 32 can be set to drive the stop block 31 to flip from the first position to the second position relative to the base 10 to release the restriction on the first rod material, so that the first rod material can be rolled out and the discharge of a single rod material is realized. Since there is no need to set a limit groove, the rod material will not encounter obstacles during the discharge process, the discharge of the rod material is stable, and there will be no jamming, thereby improving the processing efficiency.

[0079] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
