Description

Technical Field

[0001] The invention relates to the technical field of hard and brittle bar processing equipment, in particular to a cutting machine. Background Art

[0002] In the prior art, the cutting machine uses a roller group to place hard and brittle bars, and a cutting device cuts the bars downward.

[0003] However, in the cutting process of such early cutting machines, when cutting the bar, the first cut requires manual determination of the bar cutting position, and then the laser marker is manually operated to align the cutter and the bar. When the equipment is working, the operator needs to be on standby for a long time around the equipment. Cutting the bar on the roller group solely by relying on the cutting mechanism requires frequent alignment operations, and the sliding of the roller group often causes the cutting device to be unable to stably cut the bar, and the bar is easy to move. Since the hard and brittle bar is always on the slide rail or is directly telescopically fixed by a cylinder, the former cutter is easy to damage the slide rail. Although the latter can lift the bar, the symmetrically arranged fixings often cause the cylinder to be tilted due to the tolerance when assembling multiple cylinders, which in turn causes the bar to deviate from the actual cutting position, and even causes the bearing capacity of the material fixing parts to deviate from the bar due to the offset. After the bar is cut, the cut-off bar or sample structure needs to be manually picked up and collected, and the sample is usually thin, and manual gripping can easily contaminate the sample. The gripping process is also prone to cause the sample to slip or break due to unstable gripping force. In addition, the operator needs to stay near the equipment for a long time, the processing efficiency is low, and the scrap rate of cutting is high. Summary of the invention

[0010] Furthermore, there are two material-carrying guide rails, which are arranged side by side with a gap between them. The material-carrying guide rails are the load-bearing wheel rows on the frame. This scheme is used to illustrate the position through which the material fixing part passes through the material-carrying guide rails to lift the hard and brittle bar material away, and the top of the material fixing part points to the gap between the two material-carrying guide rails.

[0011] Furthermore, a negative pressure hole is provided on the surface of the material fixing suction cup, and the negative pressure hole is connected to the negative pressure pipeline.

[0045] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0046] Please also read Figures 1 to 10 This embodiment discloses a cutting machine lifting and taking film mechanism ( Figure 2 and Figure 3In order to more clearly show the lifting and feeding assembly 40 and hide the film taking assembly 50), the cutting machine is provided with a base 10 and a material carrying rail 20. The material carrying rail 20 is assembled on the base 10 and is used to assemble hard and brittle material rods. The hard and brittle material rods are placed on the material carrying rail 20, and the two ends of the material carrying rail 20 are respectively a feeding end 21 and a separation end 22. In addition, it also includes a cutting assembly 30, a lifting and feeding assembly 40 and a film taking assembly 50. The cutting assembly 30 is arranged above the material carrying rail 20, and includes a cutting bracket 31, a cutter rail 32, a cutter 33, a cutter elevator 34, a dustproof box 35 and a visual sensor 37. The cutter rail 32 is arranged on the cutting bracket 31 and is arranged in the height direction. The cutter 33 is slidably connected to the cutter rail 32 through a slider. The cutter 33 uses a wire saw, and the cutting end of the wire saw faces the direction of the material carrying rail 20. The cutter lift 34 is connected to the cutter 23 in a transmission manner, and is used to drive the cutter 33 to move on the cutter guide rail 32 (in this embodiment, the cutter lift is a motor, which is mounted on the cutting bracket, and the power output shaft of the motor is connected to the worm, and through the threaded hole provided on the cutter that matches the worm, the motor rotates, and the worm is driven to rotate forward and reversely to drive the cutter to rise and fall on the cutter guide rail). The dust box 35 is arranged above the cutting end of the cutter 33, and is arranged on the side of the cutting bracket 31 facing the feed end 21 of the material carrying guide rail 20, and a dust cover 36 is hinged at the bottom of the dust box 35. The visual sensor 37 is connected in the dust box 35, and the detection end of the visual sensor 37 faces the direction of the material carrying guide rail 20. The lifting and feeding assembly 40 and the film taking assembly 50 are arranged at one end of the material carrying guide rail 20 facing the separation end 22. The lifting and feeding assembly 40 includes a feeding guide rail 41, a feeding slide seat 42, a feeding slide seat driving motor 43, a feeding slide elevator 44, and a material fixing member 45. The feeding guide rail 41 is assembled on the base 10 and is arranged along the length direction of the material carrying guide rail 20. The feeding slide seat 42 is slidably connected to the feeding guide rail 41 through a slider. The feeding slide seat driving motor 43 is transmission-connected to the feeding slide seat 42, and is used to drive the feeding slide seat 42 to move on the feeding guide rail 41. The feeding slide elevator 44 is hinged on the feeding slide seat 42, and a lifting end is provided above the feeding slide elevator 44. The material fixing member 45 is slidably connected to the feeding sliding seat 42 and connected to the lifting end of the feeding sliding lift 44. The material fixing members 45 are symmetrically arranged, and the top surfaces of the symmetrically arranged material fixing members 45 are inclined toward the center direction between the two material fixing members 45. The film taking assembly 50 is connected to the feeding sliding seat 42, and is arranged at one end of the material bearing guide rail 20 facing the separation end 22, and includes a film taking guide rail 51, a suction cup assembly seat 52, a suction cup motor 53 and a material fixing suction cup 54.The film taking guide rail 51 is arranged above the material carrying guide rail 20, and one end of the film taking guide rail 51 faces the outside of the material carrying guide rail 20 (in the present embodiment, the film taking guide rail is arranged perpendicular to the material carrying guide rail in the horizontal direction, so that the sample pieces can be stored in the receiving box arranged on one side of the cutter. In other embodiments, the film taking guide rail can also be arranged at any angle along the horizontal direction of the material carrying guide rail to adapt to the relative placement position between the cutter and the receiving box, and can also be arranged at any angle with the material carrying guide rail in the height direction to realize the upward conveyance of the sample pieces to leave the position of the cutter). The suction cup assembly seat 52 is connected to the film taking guide rail 51 through a slider. The suction cup motor 53 is in transmission connection with the suction cup assembly seat 52 and the film taking guide rail 51 (in the present embodiment, the suction cup motor can be equipped with transmission teeth on its power output shaft, adapted to the rack arranged in parallel with the film taking guide rail, so as to realize the movement of the suction cup assembly seat relative to the film taking guide rail. The suction cup motor can also be assembled on the guide rail, and the worm connecting the transmission shaft cooperates with the threaded hole structure on the suction cup assembly seat to realize the movement of the suction cup assembly seat relative to the film taking guide rail). The disk surface of the material fixing suction cup 54 faces one end surface of the hard and brittle rod material, and is provided with a negative pressure hole 55. The negative pressure hole 55 is connected to the disk surface of the material fixing suction cup 54, and is connected to the negative pressure pipeline. A lifting device is provided under the material bearing guide rail, which is used to lift the hard and brittle material rod upward from the material bearing guide rail and move it along the length direction of the material bearing guide rail.

[0047] According to the above structure, during the operation of the lifting and picking mechanism of the cutting machine, the operator marks the line to be cut on the hard and brittle bar, pushes the hard and brittle bar onto the material carrying guide rail, and moves along the length direction of the material carrying guide rail toward the end where the material fixing suction cup is located. When it moves to the bottom of the cutting position of the cutting device, the laser marking device preset on the cutting machine is aligned with the cutting line on the hard and brittle bar, or the visual sensor captures the cutting line on the hard and brittle bar, the lifting device stops moving toward the material fixing suction cup, lifts the feeding assembly and the lifting device preset on the cutting machine, and lifts the hard and brittle bar. When lifting the hard and brittle bar, the material fixing part can make the surface of the hard and brittle bar squeeze into the space between the material fixing parts, so as to adapt to the uneven outer surface of the bar. The feeding sliding lifter hinged on the feeding sliding seat slides the material fixing part to the feeding sliding seat. Relying on the rotation ability of the hinge point and the sliding connection mechanism, it can cooperate with the sliding connection mechanism to stabilize the lifting direction of the material fixing part, replace part of the lifting stroke of the cylinder, and avoid a large amount of deviation. It is convenient to reduce the tolerance of the material fixing part when contacting the bar during installation, stabilize the cutting position of the bar, and adapt to bars of different sizes. The hard and brittle bar leaves the material bearing rail, but keeps the state of lifting the hard and brittle bar away from the material bearing rail. At this time, the hard and brittle bar is fixed by a manual or mechanical suction cup, a clamping claw or an electric / hydraulic telescopic device, and the lifting feeding assembly lowers the cylinder and moves along the feeding rail, so that the end face of one end of the hard and brittle bar contacts the disk surface of the material fixing suction cup. After the material fixing suction cup contacts the end face of the hard and brittle bar, the negative pressure pipeline works through the negative pressure device to extract the air between the end face of the hard and brittle bar and the material fixing suction cup, so that the material fixing suction cup is close to the end face of the hard and brittle bar. The cutting assembly sends an electrical signal to the control module such as the PLC to control the operation of the cutter elevator and the start of the cutter. The cutter elevator drives the cutter to move downward, so that the cutting end of the cutter starts to cut the hard and brittle bar until the cutting is completed. The bar is clamped by manual push or mechanical claws, hydraulic telescopic rods / pneumatic telescopic rods and pushed to the separation end for a preset distance to continue the cutting operation. The wire saw cutting area is set horizontally, and the debris during the cutting of the hard and brittle bar is scattered in the horizontal direction. The dust box set above the cutting area of ​​the cutter prevents the fragments and powder scattered and splashed along the cutting direction of the cutting area from scattering to the dust box set just above, so that the dust cover at the bottom of the dust box can be detected by the visual sensor when it is open. In some preferred embodiments, a dust cover made of transparent plastic can also be used to perform inspection without opening the dust cover. The dust cover can be opened during maintenance or debugging to further reduce the impact of environmental dust and debris on the visual sensor. During the cutting process, the material fixing suction cup is convenient for stabilizing the end face of the hard and brittle bar in the cutting state, so as to avoid the cutter's frictional force causing the cut material to deviate or rotate during the cutting process as the connection area of ​​the cutting area gradually shrinks, thereby avoiding the breakage of the cut material before the cutting is completed.After the cutting is completed, the cut sample or block is attached to the material fixing suction cup due to suction, and then the suction cup motor is started to drive the suction cup assembly seat to move on the sheet taking guide rail, away from the material carrying guide rail, and placed in the material receiving box. Air is introduced into the negative pressure pipeline, and the material fixing suction cup loses suction, so that the sample or block is placed in the material receiving box. By setting a suction cup at the separation end of the material carrying guide rail, the sample is fixed by the negative pressure pipeline, and the sample is moved out of the material carrying guide rail by the sheet taking guide rail. Compared with hand-held samples, the probability of sample fragmentation is reduced, and the automation of cutting machine material taking is realized.

[0048] In the above embodiment, the lifting mechanism for lifting hard and brittle bars, in addition to the lifting and feeding assembly connected to the sheet picking mechanism, can also be provided with more than one lifting device slidably connected to the feeding guide rail. The device can use a cylinder, and the telescopic section of the cylinder is also provided with a material fixing part to contact the hard and brittle bars, and cooperate with the lifting and feeding assembly to lift the entire section of the hard and brittle bars off the material carrying guide rail.

[0049] See also Figure 2 In some preferred embodiments, the number of the material fixing members 45 is four, and they are symmetrically arranged at the midpoints of the four material fixing members 45. By providing four material fixing members and symmetrically arranging them along the midpoints, the uneven outer surface of the hard and brittle bar material can be fixed at multiple points through multiple material fixing members, and under the action of gravity, the hard and brittle bar material can be fixed by the top surfaces of the material fixing members that are relatively and inclined.

[0050] See also Figure 3 In some preferred embodiments, the lifting and feeding assembly 40 further includes a sliding shaft 46 and a fixing assembly plate 47. The sliding shaft 46 is vertically arranged on the feeding sliding seat 42. The lifting end of the feeding sliding elevator 44 is connected to the fixing assembly plate 47. The fixing assembly plate 47 is sleeved on the sliding shaft 46. The material fixing part 45 is connected to the fixing assembly plate 47. By providing the sliding shaft and the fixing assembly plate, the sliding connection of the material fixing part on the feeding sliding seat is realized, so that when the feeding sliding elevator lifts the material fixing part, the lifting direction can be limited by the sliding shaft, thereby improving the lifting accuracy and stability of the material fixing part.

[0051] See also Figure 3 In some preferred embodiments, the feed slide seat 42 is a U-shaped bracket, and the feed slide lifter 44 is hinged on the bottom surface of the U-shaped bracket. By setting the U-shaped bracket, it is convenient to place the feed slide lifter inside the feed slide seat, avoiding the problem of the protruding feed slide lifter causing the overall structure to be too high.

[0052] See also Figure 3In some preferred embodiments, the feeding sliding seat 42 is slidably connected to the feeding guide rail 41 through a slider, and the slider is arranged on both sides of the feeding sliding seat 42.

[0053] See also Figure 3 In some preferred embodiments, the feeding slide seat driving motor 43 is arranged on one side of the feeding slide seat 42 and is slidably connected to the feeding guide rail 41 through a gear rack.

[0054] See also Figure 3 In some preferred embodiments, there are two material-carrying rails 20 , which are arranged side by side, with a gap between the two material-carrying rails, and the top of the material fixing member points to the gap between the two material-carrying rails.

[0055] See also Figure 3 In some preferred embodiments, a cylinder 48 is further included, and the two ends of the cylinder 48 are respectively connected to the material fixing member 45 and the feeding sliding seat 42. By setting the cylinder, it is convenient to further lift the hard and brittle bar material.

[0056] See also Figure 3 In some preferred embodiments, a soft material layer is provided on the top surface of the material fixing member 45. The soft material layer can be made of plastic or rubber. By providing the soft material layer, the compression deformation of this part can be achieved, thereby further improving the adhesion efficiency of the hard and brittle rod material.

[0057] Please also read Figure 5 as well as Figure 6 In some preferred embodiments, the number of the material fixing suction cups 54 is more than two (in this embodiment, the number of material fixing suction cups selected is 4). The material fixing suction cups are symmetrically arranged along the central direction of the suction cup assembly seat. By arranging multiple material fixing suction cups, the suction force required to fix the sample is dispersed from a single suction cup to multiple suction cups, which facilitates uniform force on the sample, avoids excessive central negative pressure suction of a single suction cup causing the sample to break, and avoids failure of a single suction cup causing the sample to be unable to be fixed, or facilitates the adaptation of suction force and fixing position of the material fixing suction cup when it is necessary to carry samples of different sizes and weights.

[0058] See also Figure 6 In some preferred embodiments, a suction cup stopper 56 is further included. The suction cup stopper 56 is mounted on the suction cup assembly seat 52. One end of the suction cup stopper 56 faces the disk surface of the material fixing suction cup 54, and a gap is provided between the suction cup stopper 56 and the disk surface of the material fixing suction cup 54. By providing the suction cup stopper, when the end of the material rod approaches the material fixing suction cup during the assembly and cutting process, it is prevented that the impact force of the sliding hard and brittle material rod is too large, causing the connection between the negative pressure hole of the material fixing suction cup and the negative pressure pipeline, and the material fixing suction cup and the suction cup assembly to break or be damaged, thereby affecting the use of the material fixing suction cup.

[0059] See also Figure 5 as well as Figure 6 In the above embodiment, a material receiving box 57 is further included. The material receiving box 57 is arranged at one end of the film taking guide rail 51 facing the outside of the material carrying guide rail 20, so as to facilitate the sample to be sent away from the area where the material carrying guide rail is located. In some preferred embodiments, the top surface of the material receiving box 57 is provided with arranged material storage slots, and by providing the material storage slots, it is convenient to store multiple samples of different sizes.

[0060] See also Figure 6 In some preferred embodiments, a sensor 28 is further included, and the sensor 58 is arranged on the suction cup assembly seat 52, and the sensing end of the sensor 58 is facing the direction of the material fixing suction cup 54 (in this embodiment, the sensor can be an infrared sensor, which relies on the infrared ranging function to display an alarm message or send a signal to the control module when the signal value reaches the specified trigger value).

[0061] Please also read Figure 7 and Fig.10 In a preferred embodiment, a cutting and pressing device is further included, and the cutting and pressing device includes a telescopic rod 38, a clamping block 39 and a cutting and pressing device assembly seat 310. The cutting and pressing device assembly seat 310 is arranged on the cutting bracket 31, and the telescopic rod 38 is arranged on the cutting and pressing device assembly seat 310, and the number is more than two. By setting the cutting and pressing device assembly seat, it is convenient to assemble the telescopic rod, and the telescopic rod is provided with a telescopic end pointing to the material bearing guide rail 20, and the clamping block 39 is connected to the telescopic end of the telescopic rod 38. By setting the cutting and pressing device, during the cutting process, the telescopic rod extends toward the material bearing guide rail, and the clamping block clamps the bar material, and the material bearing guide rail or the fixing mechanism fixed under the hard and brittle bar material is used to fix the hard and brittle bar material during cutting to ensure the stability of the bar material.

[0062] See also Fig.10 In some preferred embodiments, a cutting and pressing device assembly seat 210 is further included, wherein the cutting and pressing device assembly seat 310 is arranged on the cutting bracket 31, and the telescopic rod 38 is arranged on the cutting and pressing device assembly seat 310, and the number is more than two. By setting the cutting and pressing device assembly seat, it is convenient to assemble the telescopic rod.

[0063] See also Figure 1In some preferred embodiments, the cutter further comprises a cutter housing 311, wherein the cutter housing 311 is provided with a feeding trough 312 facing downward, and the cutting end of the cutter 33 is arranged at the bottom of the feeding trough 312. The cutting end extends into the cutter housing from the side of the feeding trough. By setting the cutter housing, the cutting end extends from the side of the cutter housing, so that the cutter housing can block the waste bar material debris in the lateral direction, and the feeding trough can be adapted to the bar material and the wire saw, so that the housing can prevent interference with the bar material during the process of the wire saw completely cutting the bar material and lowering.

[0064] See also Figure 1 In the above embodiment, the dust box 35 is arranged on the cutting bracket 31 at the top of the feeding chute 312. By arranging the dust box on the cutting bracket at the top of the feeding chute, when the cutter cuts the bar material downward during the cutting process, the cutting area always keeps a distance from the dust box to prevent the debris from contacting the dust box in large quantities. The visual sensor in the dust box installed on the cutting bracket does not follow the rise and fall of the cutter, and the preset marking line on the bar material can be detected in real time during the cutting process. If the bar material is displaced, a signal can be sent to the controller or the alarm device to facilitate the operator to perform further correction operations.

[0065] See also Figure 1 The cutter housing 311 is provided with an inspection cover 313, which is hinged to the cutter housing 311, and the cutter 33 is arranged in the space between the inspection cover 313 and the cutter housing 311.

By setting the dust cover opening and closing rod, the dust cover can be opened and closed conveniently.

[0067] In the above embodiment, the material fixing suction cup uses negative pressure to fix the side of the hard and brittle bar before the cutter cuts it. In other preferred embodiments, the side of the hard and brittle bar can also be contacted and the sample can be fixed during the process of the cutter cutting the hard and brittle bar.

[0068] In the above embodiment, the cutter may be a wire saw.

[0069] In the above embodiment, the material fixing suction cup is connected to the negative pressure pipeline by setting a negative pressure hole, and the negative pressure of the negative pressure generating end (such as a negative pressure fan, a negative pressure cylinder and other structures) is used to achieve adsorption of the side of the hard and brittle material rod. In other embodiments, a mechanical suction cup can also be used to push the hard and brittle rod material so that the end is pressed on the suction cup to achieve adsorption, and the operator can flick the suction cup to achieve the detachment of the sample.
