Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cutting equipment for chip electronic components, and particularly to a cutting machine.
Background Art
[0002] In the process of automated production and processing, material supply equipment is usually required to improve processing efficiency. For example, in the cutting process of chip resistors or chip capacitors, in order to improve production efficiency, a feeding device is usually used for material supply to replace manual feeding. Existing cutting machines have the following several disadvantages:
[0003] Firstly, after the existing feeding device is fixed on the machine table, it can basically only move up and down for feeding, and cannot move horizontally outside the machine table. When the feeding device needs to add materials, the hand needs to reach into the processing area of the machine table. On the one hand, the internal space of the machine table is limited and inconvenient for operation. On the other hand, reaching the hand into the internal processing area of the machine table undoubtedly poses a safety hazard, and workers are prone to injury when operating improperly. Therefore, in order to avoid workers being injured when adding materials and for convenient operation, it is necessary to stop the machine, which undoubtedly delays a certain amount of time.
[0004] Secondly, for chip resistors or chip capacitors in the semiconductor industry, during their manufacturing process, a vacuum suction device is usually used to suck and move the whole piece of resistor or capacitor to the workbench, and then cut into individual chip capacitors or chip resistors. Since the chip resistor or chip capacitor is very thin and soft in texture, when vacuum adsorbed, the suction nozzle or suction cup is easy to deform the chip resistor, causing upward protrusions or bulges at the contact position of the suction nozzle or suction cup, which affects the quality of the chip resistor or chip capacitor;
[0005] Thirdly, during the production process, when the blade repeatedly cuts chip electronic components, the cutting edge part of the blade will wear and break, resulting in notches, which will affect the cutting accuracy and effect. And the existing blade does not have a detection mechanism, and it can only be found that the blade is damaged during the later inspection process after cutting waste materials are generated. This is just mending the fold after the sheep is lost, and the generated waste materials cannot be saved. On the other hand, since the cutting of chip electronic components requires high precision and the thickness of chip electronic components is very thin, the cutting edge part of the blade is very delicate. In the prior art, even if the cutting edge needs to be inspected in advance, it is only observed by the naked eye. One is that the blade is installed inside the cutting machine and is not convenient to view; the other is that the cutting edge itself is very small, and the notches or wear on the cutting edge are even more difficult to observe.
[0006] Finally, during the process of repeated cutting of the blade, chip residues will be generated at the cutting edge of the chip electronic component, which is easy to adhere to the cutting edge and also affects the cutting.

Detailed implementation manners
[0101] In the description of the present invention, it should be understood that the description of the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention.
[0102] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0103] The overall concept of the implementation of the present invention is as follows:
[0104] (1) The sliding table 32 is slidable relative to the support frame 31. The material support plate 33 and the material accommodating cavity are arranged on the sliding table 32, so that the material accommodating cavity can be slid out of the working area without stopping the machine. Only standby for a certain period of time, and materials can be placed outside, which is convenient for operation, improves work efficiency, and the hand does not need to reach into the machine, eliminating potential safety hazards.
[0105] (2) The limiting side plate 34 is slidably connected to the sliding table 32, so that the size of the material accommodating cavity is adjustable, thereby adapting to the material processing requirements of different specifications and having a wider range of use.
[0106] (3) The lifting device 35 is provided to lift the material, which is convenient for sucking the material and prevents the limiting side plate 34 from interfering with the material in the material accommodating cavity in the height direction.
[0107] (4) The locking device 91 and the latch 92 are provided so that the sliding table 32 can be fixed, facilitating the suction of the materials in the material accommodating cavity during processing and preventing the sliding of the sliding table 32 during processing, which may affect the processing.
[0108] (5) The sliding table 32 is further provided with a handle 324 for easy pushing and pulling.
[0109] (6) The tool inspection module 702 is provided. The light source 7022 irradiates the cutting edge part of the blade 81, and the imaging device 7021 takes a picture of the cutting edge part, thereby forming an image of the cutting edge part. In a specific implementation, the imaging device 7021 can be connected to the control device 2, and the control device 2 then transmits the image to the display screen to display the image for easy observation. Thus, the integrity of the cutting edge part can be inspected before production, problems can be discovered in a timely manner, and the rejection rate of subsequent production can be reduced.
[0110] (7) The tool wiping module 703 is provided. The first driving device 7031 drives the tool wiping head 7032 to adjust the front and rear positions of the tool wiping head 7032, facilitating the full utilization of the tool wiping head 7032. If the first driving device 7031 is not provided to adjust the front and rear positions of the tool wiping head 7032, tool wiping can also be achieved. However, the position where the tool wiping head 7032 contacts the cutting edge is the same. Since the cutting edge is sharp, a slit will be cut on the tool wiping head 7032 after a period of use. When the slit gradually increases, tool wiping cannot be performed, and other parts of the tool wiping head 7032 are not utilized, resulting in complete waste. Then, the tool wiping head 7032 wipes the cutting edge part of the blade to wipe off the contaminated chips, reducing the interference of the chips, ensuring the processing accuracy, and reducing the rejection rate.
[0111] (8) The crank rotating shaft 706 and the rotary driving device 705 are provided to facilitate the first driving device 7031 to adjust the front and rear positions of the tool wiping head 7032 and prevent interference. During tool wiping, the tool wiping head 7032 contacts the cutting edge of the blade 81, and it is ensured that the cutting edge part is completely embedded in the tool wiping head 7032, and the thickness of the tool wiping head 7032 is greater than the embedding depth of the cutting edge part to prevent the tool wiping head 7032 from being cut. When adjusting the position, the rotary driving device 705 drives the crank rotating shaft 706 to rotate, thereby driving the tool wiping head 7032 to rotate and rotate to a position lower than that during tool wiping, so that the tool wiping head 7032 and the cutting edge part do not contact first to avoid interference and affect the position adjustment.
[0112] The tool wiping head 7032 is rotatably sleeved on the crank rotating shaft 706, so that during tool wiping, the tool wiping head 7032 can rotate, further ensuring more uniform circumferential use of the tool wiping head 7032.

At this time, it is in a predetermined material suction position, which is convenient for sucking materials during processing, and will not cause the sliding table 32 to slip during the material suction process, interfering with the material suction.
[0143] In a specific embodiment, the locking device 91 and the lock catch 92 adopt the existing Omron D4SL access control lock. During use, the locking device 91 is communicatively connected to the control device 2, and the control device 2 controls the locking device 91 to lock or unlock. When the lock catch 92 is inserted into the lock, it automatically locks, ensuring that during the working process, the sliding table 2 will not be pulled out due to misoperation, resulting in the material accommodation cavity and the materials therein being pulled out. After locking, the access control lock will send a signal to the control device 2 to notify the control device 2 that it has been locked. When unlocking, the control device 2 sends a signal to the access control lock, and the access control lock releases the lock catch 92, so that the sliding table 32 can be pulled out. And in case of power failure, this access control lock also has the function of manual unlocking.
[0144] Of course, in other embodiments, other forms of locks can also be used. It is not necessarily required to use an electronic intelligent lock, and a detachable plug-in form can be directly adopted.

In a specific embodiment, the adjusting bolts 10 can adopt self-locking bolts, which are convenient for installation and adjustment.
[0148] There are at least four of the scales 30; the scales 30 are fixedly connected to the sliding table 32 and are located below the horizontal fixing plate 341; and there is at least one scale 30 below each horizontal fixing plate 341; the scales 30 are arranged in parallel along the length direction of the strip-shaped grooves 323.

In a specific embodiment, the imaging device 7021 can be a camera, the lens of the camera and the light source 7022 are arranged facing each other, and the blade 81 is located between the two. Thus, the light source 7022 irradiates the cutting edge of the blade 81, and the camera takes a photo. Since a part of the light is blocked by the cutting edge, the camera takes a black-and-white photo of the cutting edge and sends it to the control device 2, and the control device 2 sends it to the display screen to display the photo, which is convenient for observing the integrity of the cutting edge, so that the damage problem of the blade 81 can be detected in time before production, and the scrap rate can be reduced.

[0167] a crank rotating shaft 706, one end is connected to the rotation driving device 705, and the other end is connected to the tool blade wiping head 7032.
[0168] Thus, the rotation driving device 705 drives the crank rotating shaft 706 to rotate, which has two states. State 1: Rotate the cutter head 7032 to a preset position, at which time the cutter head 7032 and the blade 81 can come into contact for blade wiping. State 2: The cutter head 7032 is located below the blade 81, and the cutter head 7032 will not come into contact with the blade 81 whether it moves forward or backward or left or right, which is convenient for adjusting the position of the cutter head 7032.
[0169] The crank rotating shaft 706 is L-shaped, that is, it includes a horizontal shaft and a vertical shaft. The vertical shaft is linearly arranged in the front-rear direction. The horizontal shaft is connected to the rotation driving device 705. In a specific embodiment, it is perpendicularly connected to the piston rod of the rotation driving device 705, and the tool head 7032 is sleeved on the vertical shaft.

This is used in the case where a two-dimensional code or barcode is set on the product.
[0176] The two suction devices 5 are respectively connected to a gas source, such as an air compressor, and are supplied with gas by the gas source.
[0177] The control device 2 adopts a combination of an existing industrial computer and a motion control card, that is, the industrial computer is connected to the motion control card, and the motion control card is respectively connected to each detection device or driving device. The host computer sends control instructions to the motion control card, and the motion control card then sends the control instructions to each electronic component. For example, the industrial computer model is EBC-GF65, and the motion control card model is TurboPMAC2-Eth-Lite. Or the control device 2 can also adopt an existing PLC.
[0178] Before production, preset the processing program.
[0179] (a1) First, perform tool inspection: The control device 2 first controls the rotation driving device 705 to rotate the wiping tool 7032 clockwise by 90°. At this time, the horizontal axis of the crankshaft 706 is in the vertical state, and the wiping tool head 7032 is rotated below the blade 81 so that the two do not contact.
[0180] Then, the control device 2 controls the light source 7022 to be energized to emit light to irradiate the blade 81, and controls the imaging device 7021 to take a picture. The imaging device 7021 transmits the taken image to the control device 2, and the control device 2 then transmits it to be displayed on the display screen 90. The taken photo can be enlarged or reduced for easy observation. When taking a picture, according to the shooting range of the camera and the width of the blade 81, if the shooting range of the camera can capture all the images of the cutting edge part of the blade 81, then when inspecting the tool, the motor 7041 does not need to work. If the cutting edge part of the blade 81 cannot be completely captured in one shot, the control program of the motor 7041 can be preset. When taking a picture, the control device 2 also controls the motor 7041 to work, so as to drive the light source 7022 and the imaging device 7021 to move linearly in the left-right direction for shooting to capture the entire cutting edge.
[0181] After the cutting edge is inspected and in good condition, perform wiping of the tool:
[0182] First, the control device 2 controls the first driving device 7031 to extend and retract back and forth to adjust the front and back position of the wiping tool head 7032 so that the wiping tool head 7032 and the blade 81 are directly opposite up and down.
[0183] Then, the control device 2 controls the rotation driving device 705 to rotate, and rotates the wiping tool head 7032 counterclockwise by 90°. At this time, the horizontal axis of the crankshaft 706 is in the horizontal state, and the cutting edge can be embedded in the wiping tool head 32. Then the control device 2 controls the motor 7041 to rotate and drive the fixed seat 701 to move linearly horizontally, driving the wiping tool head 7032 to move linearly in the left-right direction to wipe the blade.
[0184] After wiping, the control device 2 controls the rotation of the motor 7041 to move the wiping cutter head 7032, the imaging device 7021, and the light source 7022 to the left or right side of the blade to avoid interfering with the cutting process.
[0185] Wherein, when a position of the wiping cutter head 7032 is worn out after use, the front and rear positions of the wiping cutter head 7032 are adjusted by the first driving device 7031 to change to another position for wiping, thereby improving the utilization rate of the wiping cutter head 7032.
[0186] Next, the material is placed:

[0189] Next, the stacked materials are placed in the material receiving cavity and on the material support plate 33; the top chip resistor is higher than the top surface of the limiting side plate 34;
[0190] Finally, the sliding table 32 is pushed back to a predetermined position, and the lock catch 92 and the locking device 91 are locked. After locking, the access control lock automatically feeds back a signal to the control device 2;
[0191] Next, the control device 2 controls the driving device 4 corresponding to the feed bin 3 to work according to a predetermined processing program, and moves the corresponding suction device 5 directly above the feed bin 3;
[0192] After reaching the position, if the driving device 4 uses a cylinder, its built-in travel switch feeds back a signal to the control device 2. The control device 2 controls the lifting mechanism 60 to work, lowers the suction device 2 to a predetermined suction position, and then the control device 2 controls the suction device 5 to suck the top chip resistor;
[0193] Then, the controller controls the lifting mechanism 60 to reset, lifts the suction device 5 and the material, and then controls the driving device 4 to drive the lifting mechanism 60, the suction device 5, and the material to move to a predetermined loading and unloading station; at this time, the control device 2 also controls the U-axis rotation system to work and move to a predetermined loading and unloading station, opposite to the material vertically and horizontally;
[0194] Next, the control device 2 controls the lifting mechanism 60 to work, and lowers the suction device 5 and the material to a predetermined position; the material is at a predetermined position on the platform of the U-axis rotation system 6;
[0195] Then, the control device 2 controls the suction device 5 to stop suction, so that the material falls onto the stage on the U-axis rotation system 6;
[0196] Then, the control device 2 controls the barcode scanner 100 to scan the QR code on the product, and the barcode scanner 100 feeds back the scanned information to the control device 2 to facilitate tracking of the production information of the product;
[0197] Next, the control device 2 controls the U-axis rotation system 6 to move to a predetermined cutting station; it is detected by the first detection device 7, and a comparison is made based on the position of the material captured by the first detection device 7 and the predetermined placement position;
[0198] Then, the control device controls the stage of the U-axis rotation system 6 to rotate to adjust the position of the material to a predetermined position;
[0199] Finally, the control device 2 controls the cutting device 8 to perform cutting according to a predetermined program;
[0200] After cutting is completed, the control device 2 controls the U-axis rotation system 6 to move to a predetermined loading and unloading station;
[0201] Then, the suction device 5 corresponding to another material bin 3 is controlled to move to a predetermined loading and unloading station; that is, the piston rod of the driving device 4 corresponding to the suction device 5 is extended to a predetermined position;
[0202] Next, the piston rod of the lifting mechanism 60 corresponding to the suction device 5 is extended to a predetermined position, and the suction device 5 is lowered to a predetermined position;
[0203] Then, the suction device 5 is controlled to adsorb the cut product;
[0204] Then, the piston rod of the lifting mechanism 60 is retracted to its original position to lift the suction device 5 and the cut product;
[0205] Next, the driving device 4 is controlled to drive the lifting mechanism 60 to move to a predetermined position, that is, directly above the material bin 3 for placing the cut product;
[0206] Then, the piston rod of the lifting mechanism 60 is extended to a predetermined position;
[0207] Finally, the suction device 5 is controlled to stop sucking air, so that the cut product falls onto the material support plate 33 of the material bin 3, completing one cutting operation.
[0208] Before the processing of the next chip resistor, the control device 2 controls the rotation of the drive motor 351 to lift the material support plate 33 and the material above it. The lifting distance can be set according to the thickness of the chip resistor, for example. That is, for each processed chip resistor, the lifting height is the thickness of one chip resistor, so that the topmost chip resistor is always above the limit side plate 34, without interfering with the suction cup 201 to pick up the chip resistor.
[0209] After the material processing is completed, the control device 2 controls the drive motor 351 to lower the material support plate 33 to its reset position, controls the suction device 5 to standby for a certain period of time, and then the control device 2 controls the door lock to unlock, so that the worker can pull out the slide table 32 to add materials. This standby time can be adjusted before actual production. During trial production, find out how much time is required for the process of adding materials, and then preset it before actual mass production.
