Description

Technical Field

[0001] The invention relates to the technical field of chip-type electronic component processing, in particular to an automatic edge removing machine. Background Art

[0002] With the development of science and technology, electronic products are becoming more and more diverse, with increasingly powerful functions and smaller sizes. This requires that the main electronic components used to manufacture electronic products, such as capacitors, resistors, inductors, sensors, etc., should be as small as possible and as reliable as possible. Currently, chip ceramic electronic components are mainly used, which have excellent performance in insulation, heat resistance, durability and other aspects. Therefore, the manufacture, sales and use of chip ceramic electronic components have been booming.

[0003] When manufacturing chip-type ceramic electronic components, a cutting machine is needed to cut the ceramic diaphragm to obtain tiny electronic components. The cutting process has very high requirements for the cutting machine, requiring the cutting machine to have a precision of micrometer level.

[0004] In the process of automated production and processing, material supply equipment is usually required to improve processing efficiency. For example, in the process of cutting chip resistors or chip capacitors, in order to improve production efficiency, material supply equipment is usually used to replace manual feeding.

[0005] For example, the publication date is March 28, 2019, and the Chinese patent application number is CN201910245250.4, which is an automatic cutting machine, including a body structure, a carrier, a detection and positioning mechanism, a cutting mechanism, a control system and two guide rails. A vacuum channel is provided inside the carrier, and on the left and right sides of the carrier, there are respectively provided with a vacuum suction cup, a transmission motor, a feeding mechanism and a receiving mechanism; the lower part of the carrier is connected to a carrying plate, and inside the connection between the carrier and the carrying plate, there is a DD direct-drive servo rotation mechanism that can allow the carrier to rotate a certain angle relative to the carrying plate, and a direct-drive mechanism that can make the carrying plate move straight forward and backward is provided under the carrying plate.

[0006] This automatic cutting machine can improve the service life of the guide rail and the running accuracy of the platform and the load plate. The electric proportional valve can accurately adjust the output force of the piston rod of the cylinder, thereby adjusting the pressure of the knife seat module on the ceramic diaphragm. The adjustment is sensitive and convenient, and the pressure can be adjusted to the optimal state according to different ceramic diaphragms, which not only ensures that the ceramic diaphragm is pressed tightly, ensures the stability of cutting, and thus ensures the quality of cutting; it also prevents the ceramic diaphragm from being crushed and causes additional damage to the ceramic diaphragm. However, when operating this cutting machine to remove scraps and cut the sides neatly, the base needs to be constantly changed in angle. When all four sides of the electronic component are to be cut off, it needs to be reciprocated four times to avoid crooked cutting. Although the accuracy is guaranteed, the cutting speed is not fast enough. For electronic components that do not require such high accuracy, the cutting efficiency cannot keep up with the demand.

[0007] Based on this, the present invention designs an automatic edge removing machine to solve the above problems. Summary of the invention

The device cooperates with the mechanical arm 4 through the CCD detector, and can complete the adjustment of the angle of the electronic component more quickly and accurately. At the same time, the device can identify the state of the electronic component raw material at the beginning, whether it is a defective scrap raw material. If it is a scrap raw material, the device does not need to complete the cutting, and the scrap raw material is directly classified and collected by the mechanical arm 4, which saves more unnecessary operating steps. The device has a higher degree of intelligence and higher processing efficiency.

[0057] The sliding tracks of the waste platform 3 and the finished product platform 31 overlap each other, and one end of the waste positioning slide rail 311 and the material taking slide rail 312 are both arranged close to the cabinet door 54 with the material taking cover 53, and the waste positioning slide rails 311 are arranged parallel to each other just above the material taking slide rail 312, which saves space and can easily switch to collect waste or finished products, and the robot arm only needs to move to the same horizontal position coordinate, which is convenient for setting parameters and convenient for operation;

[0058] The waste platform 3 and the waste slide rail 301 are at the same height as the material taking port 55. One end of the waste platform 3 and the waste slide rail 301 can slide horizontally and extend outside the material taking cover 53.

With such a structural design, the waste platform 3 can be extended outside the protective cabinet 51 without stopping the device, so as to facilitate the inspection of the defect of the sheet electronic components for adjustment and repair.

[0059] The silo slide rail 342 and the waste slide rail 301 are parallel to each other, and the outer ends of the silo slide rail 342 and the waste slide rail 301 are arranged facing the cabinet door 54 on the same side of the protection cabinet 51, so as to facilitate simultaneous material taking and discharging;

[0060] Bevel cutter 221, pressing plate 222 and bending plate 223, the pressing plate 222 is installed against the inner wall of the bevel cutter 221 by means of a spring and a slide rail so as to slide up and down, the sliding displacement between the bevel cutter 221 and the pressing plate 222 does not exceed 2 mm, the bevel cutter 221 is locked on the telescopic end of the cutter cylinder 23, the bending plate 223 is fixedly locked against the outer side of the bevel cutter 221, and the bending plate 223 is against the top of the suspended electronic component extending out of the lower blade 21;

Such a structure can cut the side of the sheet-like electronic component more neatly, and because one side of the sheet-like electronic component is suspended outside the cutting table 32, there is no need to clean up the scraps, only cutting is required, and the cutting speed is faster and the efficiency is higher;

[0062] The master controller 1 is provided with a manual button, and the master controller 1 is also controlled by a display 11 and an operation keyboard 12. Such a master controller 1 is a controller of a CNC machine tool, which is convenient for parameter setting and CNC. At the same time, basic operations such as shutdown, start-up, and emergency stop can also be performed manually. The operation of any electric control or pneumatic device of the entire equipment can also be controlled by operating the keyboard 12;

[0063] The robot arm 4 is a four-axis robot arm; locking electromagnets are provided on all working positions of the scrap table 3, the finished product table 31 and the feeding table 33. Such a structure enables the robot arm 4 to transfer the sheet electronic components to the table, change the angle, position and move down, etc., so as to facilitate the cutting.

Such a structure enables the loading suction cup 341 to suck the sheet electronic components to the feeding table 33 without affecting the robot arm, and can be carried out simultaneously;

[0066] The suction cup surface of the robot arm suction cup 41 is a flat surface, on which a plurality of negative pressure air holes 411 are provided, all of which are connected to an external negative pressure generating device, and the diameter of the negative pressure air holes 411 is no more than 5 mm, so that the robot arm suction cup 41 of the device can smoothly adsorb the sheet-like electronic components, and the size of the negative pressure air holes 411 is small, so the suction point of the sheet-like electronic components will not be sucked out of the groove, thereby reducing losses.

[0067] In a specific embodiment of the present invention:

[0068] The embodiment of the present invention provides an automatic edge removal machine, and the technical problems solved by the present invention are as follows: 1. When the existing equipment cuts chip electronic components, because of the high precision, the chip electronic components must be adjusted to return to their original positions each time they are cut to avoid misalignment. Therefore, there are many steps in cutting, which is relatively complicated and inefficient; 2. Because the CCD detectors in the current cutting equipment are used to detect the raw material position of the chip electronic components, rather than to detect whether the raw materials of the chip electronic components meet the cutting requirements, the current cutting device does not have the identification function, and all chip electronic components in the raw material position will be cut according to the set action; 3. There is no classification of qualified products. In order to reduce the capacity of chip electronic components and scrap products, all chip electronic components will be put together, and the existing chip electronic components that are broken, qualified, and unqualified by raw materials will be put together. A separate screening device will be needed in the later stage, because the cutting accuracy of such chip electronic components is very high, and it is difficult to monitor them with a lot of manpower, and the screening device needs to be repositioned, which greatly reduces the production speed of finished products; 4. Because the chip electronic components cannot be distinguished during production, it is only possible to determine whether there is a problem with the equipment by statistically analyzing the overall data, such as the whole month or week. It is also impossible to determine what the problem is, and there is no way to observe it in a targeted manner. It can only be slowly inferred and repaired, which is very time-consuming and labor-intensive.

[0069] The technical effects achieved are:

[0070] 1. The device can identify whether the raw materials meet the cutting requirements through multiple cutting CCD detectors 6 and feeding CCD detectors 61, and can also identify whether the edges and sizes of the finished chip electronic components meet the preset requirements. Therefore, whether the raw materials of chip electronic components or the semi-finished products in the cutting process, as well as the semi-finished products after cutting, the device can identify whether they are qualified products, and can use the robot arm 4 to send the raw materials of chip electronic components from the feeding table 33 or the cutting table 32 to the waste table 3 or the finished product table 31 for classification;

[0071] 2. Moreover, the device can directly remove the chip electronic components identified as waste materials through the mechanical arm 4, so the unqualified chip electronic component materials on the feeding table 33 are directly sent to the waste table 3, and it is no longer necessary to complete all the operation and cutting steps, thus avoiding invalid cutting operations, simplifying the cutting operation steps of the equipment, and improving the effective working efficiency of the device;

[0072] 3. Because this type of cutting device is automated, it is very dangerous for personnel to approach when the machine is turned on, so the protective cabinet 51 is required to isolate the equipment. When taking raw materials or equipment, the isolated protective cabinet 51 needs to be opened, which is very dangerous and requires shutdown. The device can send the waste table 3 out of the protective cabinet 51 through the automated operation of the material taking port 55 and the waste slide rail 301, so that the waste table 3 is outside the dangerous working environment, that is, in a safe range, and then the waste can be directly taken without stopping. The setting of the device can timely check the cause of the waste, and at the same time can check the operation of the equipment through the observation window 52, ​​so as to make timely adjustments to avoid problems with the chip electronic component raw materials due to the operation of the device and reduce losses;

[0073] 4. When the device suddenly finds that there are a lot of scrap materials on the scrap table 3, it will observe the situation of the equipment in time. The robot arm 4 directly sends the raw materials to the scrap table 3; puts them into the cutting table 32, and then directly puts them into the scrap table 3 after being monitored by the cutting CCD detector 6; and puts them into the scrap table 3 again after the cutting is completed; through the three different operation modes of the robot arm 4, it is easy to determine which step has a problem, and then it is easy to check the problem through the observation window 52, ​​which is convenient for maintenance and troubleshooting.

[0074] The technical solution in the embodiment of the present invention is to solve the above problems, and the overall idea is as follows:

[0075] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The waste platform 3, the finished product platform 31, the cutting platform 32, the feeding platform 33, the raw material bin 34 and the mechanical arm 4 are installed on the top of the rack platform 5. The cutting platform 32 needs to be fixed and locked. The position relationship is as follows: Figure 5 and Figure 6 As shown, the waste table 3 is horizontally slidably mounted in the waste slide rail 301, and the waste slide rail 301 is horizontally slidably mounted on the waste positioning slide rail 311, and the finished product table 31 is horizontally slidably mounted on the material collection slide rail 312, the feeding table 33 is horizontally slidably mounted on the transfer slide rail 331, the raw material bin 34 is mounted on the bin slide rail 342 and slides horizontally, the waste positioning slide rail 311, the material collection slide rail 312, the transfer slide rail 331 and the bin slide rail 342 are all fixedly mounted on the frame table 5, as shown in FIG. Figure 5 As shown, the waste slide rail 301, the waste positioning slide rail 311, the material taking slide rail 312, the transfer slide rail 331 and the silo slide rail 342 are arranged in a Figure 5The cabinet door 54 can slide in the vertical direction, that is, it can slide linearly between the inside of the rack 5 and the cabinet door 54.

[0077] When the present invention is used, the equipment is ensured to be in a stopped state, and then a stack of chip electronic component raw materials, generally within 100 pieces of chip electronic component raw materials, is placed in the raw material bin 34 and stacked neatly. The four sides of the raw material bin 34 are provided with limit blocks, which are consistent with the size of the raw materials and are used to ensure that the chip electronic component raw materials are neatly stacked and will not be displaced. It belongs to a commonly used device;

[0078] Then, the device is powered on and ventilated through the main controller 1, which is used to drive the electric or air cylinder and the negative pressure generating device, and then the coordinate points of the waste table 3, the finished product table 31, the cutting table 32, the feeding table 33, the raw material bin 34 and the robot arm 4 are input into the system of the main controller 1. A small computer is provided inside, which is operated by operating the keyboard and mouse, and the information is checked through the display 11. This operating system is a commonly used system that can be purchased from outside, and the coordinates and operation steps are set;

[0079] Start the equipment, the feeding suction cup 341 starts the negative pressure to suck one of the chip electronic component raw materials in the raw material bin 34, and then sucks a piece of electronic component raw material through the cylinder and retracts upward, the feeding table 33 slides under the action of the driving motor and moves to the position directly below the feeding suction cup 341, which is also a pre-set coordinate point on the frame table 5, the feeding suction cup 341 gently puts the sucked piece of electronic component raw material on the feeding table 33, the negative pressure of the feeding suction cup 341 disappears, and a piece of electronic component raw material is placed on the feeding table 33, and the feeding table 33 slides to a position close to the cutting table under the action of the driving motor, such as Figure 5 and Figure 6 At this time, the loading CCD detector 61 is in real-time monitoring mode, and the surface and shape of the electronic components on the feeding table 33 are checked to see if there are any problems.

[0080] Next, the robot arm 4 moves to the top of the feeding work position of the feeding table 33, and the robot arm suction cup 41 starts to generate negative pressure. The robot arm suction cup 41 extends downward to absorb the electronic component and then retracts to raise the electronic component.

[0081] If there is a problem with chip electronic components, scrap recycling operations are carried out;

[0082] If there is no problem with the chip electronic component at this time, the feeding table 33 will immediately suck up another chip electronic component in the raw material bin 34 through the loading suction cup 341, and the feeding table 33 will move the raw material to the feeding work position for standby.

[0083] The waste recycling operation is as follows: the main controller 1 receives a signal that waste needs to be recycled, and first controls the upper blade 22 on the cutting frame 2 to be in its original position, and the waste table 3 is moved to the working position under the action of the driving motor controlled by the main controller 1, and the waste table 3 is blocked just above the finished product table 31. The robotic arm 4 moves the robotic arm suction cup 41 to just above the pre-set working position of the waste table 3, and then all the negative pressure in the negative pressure vents 411 of the robotic arm suction cup 41 is canceled, and the robotic arm 4 directly sends the scrapped products to the waste table 3, and returns to the new position above the feeding working position of the feeding table 33 to pick up the materials. At the same time, the waste table 3 returns to the outer end of the waste positioning slide rail 311 close to the cabinet door 54, without blocking the finished product table 31.

[0084] If any CCD detector of the device detects that the sheet-shaped electronic component raw materials have problems and are unqualified raw materials, waste material recovery operations will be carried out.

[0085] If there is no problem with the chip electronic component, the robot arm 4 rotates to move the robot arm suction cup 41 to the top of the cutting table 32, and controls the robot arm suction cup 41 to extend, and places the electronic component at the preset position of the cutting table 32. One side of the electronic component extends out of the cutting table 32 where the lower blade is installed, and one side of the electronic component is suspended. At this time, the robot arm suction cup 41 presses the electronic component on the cutting table 32 without moving or damaging the electronic component. The cutting CCD detector 6 starts to check the position of the chip electronic component and the shape of the incision around it. If it meets the requirements, the cutting cylinder 23 of the cutting frame 2 is controlled to extend, and the upper blade 22 cuts downward to ensure that the pressure plate 222 and the top of the lower blade 21 press the chip electronic component, and at this time, the bending plate 223 bends the chip electronic component that is suspended and extends out of the lower blade 21. Fig. 9As shown, the stress is concentrated in the bent part, so when cutting, the force can be fully applied to the part that needs to be cut, so that the effective part of the electronic component is not easily cut, broken or damaged, and it is easier to cut one side of the chip electronic component neatly after bending, avoiding cutting and breaking of the effective part of the chip electronic component, and the inclined cut of the bevel cutter 221 on the upper blade 22 is aligned with the cutting edge of the lower blade 21 to cut the side of the chip electronic component neatly. After the cutting is completed, the blade 22 and the bending plate 223 are locked as a whole by bolts, and the pressure plate 222 and the upper blade 22 are installed through springs and slide grooves. The upper blade 22 is limited to slide up and down only against the right side wall of the bevel cutter 221, and the spring is tightened so that the pressure plate can only float up and down. The pressure plate 222 can slide upward along the bevel cutter 221 of the upper blade 22 by no more than 2 mm. When the upper blade 22 rises, the pressure plate 222 immediately rises and returns to the initial position, flush with the bottom of the inclined cutting edge of the bevel cutter 221 of the upper blade 22. A plurality of cutting CCD detectors 6 are installed on the cutting table 32, all of which are aligned with the cutting position. Once a cutting notch is found in the effective part of the chip electronic component, the chip electronic component is scrapped and the waste recycling operation is carried out.

[0086] If there is no problem, the robot 4 controls the robot suction cup 41 to absorb the sheet electronic component and rise it until it is not in contact with the cutting table 32. The robot 4 controls the robot suction cup 41 to rotate along the axis, driving the sheet electronic component to change direction, so that the other side is in the cutting position, and cutting is performed until all four sides are cut off. The robot 4 controls the robot suction cup 41 to absorb the sheet electronic component and move it to the top of the finished product table 31, and places the sheet electronic component on the finished product table 31. Then the negative pressure vent 411 of the robot suction cup 41 is controlled to lose the negative pressure, and the finished sheet electronic component with four sides removed and cut is placed on the finished product table 31. Then the robot 4 returns to the top of the feeding work position of the feeding table 33. Figure 5 Position shown;

[0087] This completes one edge removal cutting operation, and repeats the next cutting operation.

[0088] When the device takes out the finished chip electronic components or puts the chip electronic component raw materials into the raw material bin 34, the equipment needs to be shut down.

[0089] Stop the machine, manually pull the finished product table 31 to make it slide on the material collection slide rail 312 to the cabinet door 54, and then take out the cut chip electronic components. Because the machine has been stopped, you can also pull the raw material bin 34 to make it slide on the bin slide rail 342 to the cabinet door 54 on the same side, put the chip electronic component raw materials into the raw material bin 34, and complete the material collection and discharge operations.

[0090] If scrap material appears in this device, a notification will be given through a prompting device, such as a flashing light, etc. The prompting device is electrically connected to the main controller 1. The prompting device notifies the staff to check. The staff views the action steps of the robot 4 through the observation window 52 to see at which step the chip electronic component failure occurs, and opens the material collection cover 53 to expose the material collection port 55. The scrap table 3 at the outer end can be manually pulled out, the scrap table 3 slides on the scrap slide rail 301, and is pulled out through the cabinet door 54 through the material collection port 55, so that the scrap table 3 is outside the protective cabinet 51. At this time, the defective position of the scrap material can be checked without stopping the machine, so as to find the problem in time and stop the loss immediately.

[0091] Description of the working positions of the waste station 3, the finished product station 31, the cutting station 32, the feeding station 33, the raw material bin 34, the loading suction cup 341 and the robot arm suction cup 41:

[0092] The working position of the waste table 3 is to manually push the waste table 3 into the protective cabinet 51, that is, when the waste slide rail 301 is retracted to the shortest position, the waste slide rail 301 and the waste table 3 are equivalent to a stretched drawer-type structure, and the waste slide rail 301 is a hinge that can be telescopically assembled into an integral square structure, and the waste table 3 is located directly above the finished product table 31. At this time, the robot arm 4 can only put the chip electronic components on the waste table 3, which is the position where the waste table 3 receives the chip electronic components. The waste table 3 has a standby position, that is, the position where the waste table 3 is not above the finished product table 31, and is also on the waste positioning slide rail 311 near the outer end of the cabinet door 54;

[0093] The finished product table 31 has only one working position, which is the position for receiving the finished chip electronic components after cutting;

[0094] The cutting table 32 has only one fixed position, which is the working position;

[0095] The feeding table 33 has two working positions, one is the feeding working position and the other is the material taking working position. The feeding working position is close to the cutting table 32, which is convenient for the material taking operation of the robot arm 4 without being blocked, that is, the position where the robot arm 4 takes away the raw materials of the chip electronic components, and the material taking working position is directly below the telescopic end of the cylinder of the loading suction cup 341, that is, the position where the loading suction cup 341 puts the raw materials of the chip electronic components into the feeding table 33;

[0096] The working position of the raw material bin 34 is directly below the telescopic end of the cylinder of the loading suction cup 341, which is the place where it overlaps with the feeding table 33, and is also the position where the loading suction cup 341 sucks the chip electronic component raw materials from the raw material bin 34;

[0097] The loading suction cup 341 has two working positions, one is the lower position and the other is the upper position. The lower working position is where the loading suction cup 341 sucks the electronic components in the raw material bin 34, and the upper working position is where the loading suction cup 341 places the sucked electronic components on the feeding table 33.

[0098] The working positions of the robot arm suction cup 41 are all the positions where the robot arm 4 needs to suck the chip-type electronic components.

[0099] The CCD detector 107 is also an existing device, for example, a CCD camera, such as Figure 3 As shown, CCD cameras are respectively arranged on both sides of the tool holder 104 for photographing the workpiece on the stage 106 .

[0100] The CCD detector is an instrument that detects the appearance of an object through a display using a CCD component.

[0101] Applicable to the flatness inspection and maintenance of various connector products such as CF CARD, FPC, BTOB, SIM CARD, etc. The coordinate line width is 1 / 2 of the existing similar products in the market, making the inspection more accurate.

[0102] Different colors of coordinate lines can be set according to the background. Four coordinate lines can be set at the same time in the normal configuration. Color CCD can also be used for product appearance inspection and can be used as a vertical projector.

[0103] It is highly versatile, and products with different material numbers can be inspected by replacing different inspection fixtures. The image on the display is directly observed with the naked eye, and the operator is not easily fatigued compared to projectors and microscopes.

[0104] The driving device used in this device includes a cylinder and a motor, which are commonly used driving devices and also a commonly used connection method. This embodiment will not be described in detail. In addition, the driving motors used in this device are all servo motors, which are convenient for precise positioning and cutting of electronic components.

[0105] The center position of the rack platform 5 of the device close to the equipment is the inner end, and the end close to the cabinet door 54 is the outer end. The inner ends and outer ends of all slide rails and parts are based on this.
