Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machines, and in particular to a fully automatic multi-layer material stacking die-cutting machine and a die-cutting method. Background Art

[0002] The die-cutting machine is an important equipment for post-printing packaging processing and forming. It is also called a die-cutting machine, a cutting machine, and a CNC punching machine. It is mainly used for die-cutting, creasing, and hot stamping operations on non-metallic materials, self-adhesive stickers, EVA, double-sided tape, rubber pads, etc. When the die-cutting machine is working, the die-cutting machine uses the downward pressing steel knife, hardware molds, steel wires and other stamping parts to roll the blank to be die-cut into the required shape or cut marks. Among them, pressing and cutting the entire printed product into a single graphic product is called die-cutting.

[0003] In the existing die-cutting of plate-shaped blanks, in order to save time and improve production efficiency, multiple layers of raw materials are stacked together, and the stacked materials are die-cut in batches by a die-cutting machine. However, when the current die-cutting machine processes elastic plates such as rubber plates in batches, since such plates have a certain ability to elastically deform, the force on the material at the bottom is significantly different from that on the top. The multiple layers of material at the bottom will undergo a certain elastic deformation, so that the die-cut product will restore its shape by itself, which leads to a certain difference between the shape of the die-cut product and the predetermined shape. Therefore, a fully automatic multi-layer material stacking die-cutting machine and a die-cutting method are proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when the current die-cutting machine processes elastic plates such as rubber plates in batches, since such plates have a certain ability of elastic deformation, the material at the bottom and the material at the top are subjected to obviously different forces, and the multi-layer materials at the bottom will undergo a certain elastic deformation, so that the die-cut product will restore its shape by itself, which will lead to a certain difference between the shape of the die-cut product and the predetermined shape. The present invention provides a fully automatic multi-layer material stacking die-cutting machine and a die-cutting method.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

The anti-deformation component includes four slide frame brackets fixedly installed at the four corners of the top of the feeding tube, the slide frame brackets are all vertically arranged, and multiple horizontally arranged long slide frames and short slide frames are fixedly installed between the two slide frame brackets on the same side. The multiple long slide frames and multiple short slide frames are staggered with each other. The long slide frames and the short slide frames on the same horizontal plane are slidably installed with the same die-cutting pad inside. The top of the die-cutting pad is provided with a placement groove adapted to the die-cutting plate, and the inside of the placement groove is provided with multiple evenly distributed feeding grooves, which are adapted to the stamping parts of the die-cutting machine body. Pad clamps are fixedly installed on one side of the die-cutting pad, and control hydraulic presses are provided on both sides of the die-cutting machine body. Multiple horizontally arranged control hydraulic rods are driven and installed on one side of the control hydraulic press, and the telescopic ends of the multiple control hydraulic rods on the same side are respectively fixedly installed on the side walls of the multiple pad clamps.

[0008] Furthermore, a vibration slide hole is opened on the top of the loading platform, a vibration plate is slidably installed inside the vibration slide hole, a vibration motor is arranged inside the loading platform, an output end of the vibration motor is connected to the bottom drive of the vibration plate, and the material discharge frame is placed on the top of the vibration plate.

[0009] Furthermore, a positioning frame adapted to the material discharging frame is fixedly mounted on the top of the vibration plate, and the material discharging frame is located inside the positioning frame.

[0010] Furthermore, a vertically arranged lifting electric push rod is provided inside the loading platform, the telescopic end of the lifting electric push rod extends to the top of the loading platform and is fixedly installed with a lifting plate, a clearance hole is provided at the bottom of the vibration plate, the lifting plate is located inside the clearance hole, and a lifting hole matching the lifting plate is provided at the bottom of the discharge frame.

[0011] Furthermore, a plurality of assembly holes are provided on the top of the die-cutting pad, fastening bolts are passed through the inside of the assembly holes, and the pad clip is fixedly connected to the die-cutting pad via the fastening bolts.

[0012] Furthermore, a limit stopper is fixedly installed on a side of the short sliding frame at the same height away from the long sliding frame.

[0013] Furthermore, a positioning bracket is fixedly installed on the top of the die-cutting table, a laser locator is fixedly installed on the top of the positioning bracket, a laser receiver compatible with the laser locator is fixedly installed on one side of the bottom end of the positioning bracket, and a plurality of die-cutting pads are located between the laser locator and the laser receiver. Positioning grooves are opened on the top of the die-cutting pads, and the positions of the positioning grooves correspond to the positions of the laser locator and the laser receiver.

[0014] A fully automatic multi-layer material stacking die-cutting method comprises the following steps:

[0015] S1. Unloading: first place the unloading frame loaded with die-cut sheets on the loading table;

[0016] S2, loading: Control the hydraulic rod to drive the bottom die-cutting pad to be set between the long slide frame and the short slide frame, and the suction cup mechanical arm places the first die-cutting plate in the placement slot, and then sets up each die-cutting pad from bottom to top in sequence. After each die-cutting pad is set up, the die-cutting plate is placed in the placement slot, and the operation is repeated until multiple die-cutting plates are stacked at the bottom of the die-cutting machine body stamping part;

[0017] S3, die-cutting: The die-cutting machine body drives the stamping parts to lower multiple die-cutting plates for batch die-cutting, so that the cut finished products fall into the discharge pipe through the discharge chute and are then transported to other stations;

[0018] S4, reset: After the die-cutting is completed, the control hydraulic presses on both sides control the multiple die-cutting pads to reset in sequence by controlling the hydraulic rods. At the same time, the suction cup robot arm transfers the waste plates after die-cutting to other areas, completing a round of die-cutting process.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention sets an anti-deformation component. When the die-cutting machine body drives the stamping part to descend and performs die-cutting on a plurality of stacked die-cutting sheets from top to bottom, each die-cutting pad will be placed at the bottom of the plurality of die-cutting sheets respectively, so that the upper and lower die-cutting sheets will not contact each other. The stamping part will only apply force to a single die-cutting sheet each time, and the pressure generated by die-cutting will only act on one die-cutting sheet, and then be transmitted to the long slide frame and the short slide frame on both sides through the die-cutting pad, thereby preventing the die-cutting sheet at the bottom that has not been die-cut from being deformed and affecting the die-cutting accuracy.

[0021] 2. The present invention sets a vibration plate, so that after the material discharging frame loaded with multiple die-cutting plates is placed on the vibration plate, the vibration motor inside the loading platform will drive the vibration plate to vibrate up and down, and then drive the material discharging frame to vibrate up and down, so that the die-cutting plates inside are separated from each other under the action of vibration, effectively preventing the die-cutting plates of materials such as plastic and rubber from being squeezed and attached to each other under the action of gravity, affecting the transfer of the die-cutting plates by the suction cup mechanical arm;

[0022] 3. The present invention sets a positioning frame, so that when the material discharging frame is placed on the vibration plate, the positioning frame can play a role in positioning the die-cutting sheet, so that the material discharging frame is kept in the same position each time it is placed, which is convenient for the suction cup mechanical arm to quickly grab the die-cutting sheet inside the material discharging frame. At the same time, the positioning frame will limit the bottom of the die-cutting sheet, effectively preventing the die-cutting sheet from sliding on the top of the vibration plate under the action of vibration when the vibration plate drives the die-cutting sheet to vibrate up and down, thereby affecting the positioning of the suction cup mechanical arm;

[0023] 4. The present invention sets a lifting plate, so that when the suction cup mechanical arm transfers the die-cutting sheet at the top to the bottom of the die-cutting machine body stamping part, the lifting electric push rod inside the loading table will drive the lifting plate to move upward, and then the lifting plate passes through the lifting hole to support the bottom of the die-cutting sheet at the bottom, and then drives all the die-cutting sheets to move up a unit distance as a whole, so that the die-cutting sheet at the top is always kept at the same height, reducing the positioning time of the suction cup mechanical arm and speeding up the grabbing and transportation of the die-cutting sheet;

[0024] 5. The present invention sets a laser locator and a laser receiver so that the laser locator can emit a positioning laser to the bottom and receive it by the laser receiver at the bottom, thereby performing positioning detection on the die-cutting pad after each installation. When a die-cutting pad fails to slide into place, the positioning groove on its top will be misaligned with all the positioning grooves below, thereby blocking the laser and making it impossible for the laser receiver to receive it, thereby triggering an alarm, so that the laser locator and the laser receiver cooperate with each other to position the die-cutting pad.

[0042] like Figure 3As shown, a vibration slide hole is provided on the top of the loading platform 1, and a vibration plate 15 is slidably installed inside the vibration slide hole. A vibration motor is provided inside the loading platform 1, and the output end of the vibration motor is drivingly connected to the bottom of the vibration plate 15, and the discharge frame 2 is placed on the top of the vibration plate 15; specifically, by providing the vibration plate 15, after the discharge frame 2 loaded with a plurality of die-cut sheets 3 is placed on the vibration plate 15, the vibration motor inside the loading platform 1 will drive the vibration plate 15 to vibrate up and down, thereby driving the discharge frame 2 to vibrate up and down, so that the die-cut sheets 3 inside are separated from each other under the action of vibration, and the die-cut sheets 3 made of materials such as plastic and rubber are effectively prevented from being squeezed and attached to each other under the action of gravity, affecting the transportation of the die-cut sheets 3 by the suction cup robot arm 4.

[0043] like Figure 3 As shown, a positioning frame 16 adapted to the discharge frame 2 is fixedly installed on the top of the vibration plate 15, and the discharge frame 2 is located inside the positioning frame 16; specifically, by setting the positioning frame 16, when the discharge frame 2 is placed on the vibration plate 15, the positioning frame 16 can play a positioning role for the die-cutting sheet 3, so that the discharge frame 2 remains in the same position each time it is placed, which is convenient for the suction cup mechanical arm 4 to quickly grab the die-cutting sheet 3 inside the discharge frame 2, and at the same time, the positioning frame 16 will limit the bottom of the die-cutting sheet 3, effectively preventing the die-cutting sheet 3 from slipping on the top of the vibration plate 15 under the action of vibration when the vibration plate 15 drives the die-cutting sheet 3 to vibrate up and down, thereby affecting the positioning of the suction cup mechanical arm 4.

[0044] like Figure 3 As shown, a vertically arranged lifting electric push rod is arranged inside the loading platform 1, and the telescopic end of the lifting electric push rod extends to the top of the loading platform 1 and is fixedly installed with a lifting plate 17.

When a die-cutting pad 11 does not slide into place, the positioning groove 1103 on its top will be misaligned with all the positioning grooves 1103 below, thereby blocking the laser and making the laser receiver 21 unable to receive it, thereby triggering an alarm, so that the laser locator 20 and the laser receiver 21 cooperate with each other to position the die-cutting pad 11.

[0048] like Fig.10 As shown, a fully automatic multi-layer material stacking die-cutting method comprises the following steps:

[0049] S1, unloading: firstly place the unloading frame 2 loaded with the die-cutting sheet 3 on the loading platform 1;

Finally, the die-cutting machine body 5 drives the stamping part to lower multiple die-cutting plates 3 for batch die-cutting, so that the cut finished products fall into the discharge pipe 7 through the discharge chute 1102, and then are transported to other stations. After the die-cutting is completed, the control hydraulic presses 13 on both sides control the multiple die-cutting pads 11 to reset in sequence by controlling the hydraulic rods 14. At the same time, the suction cup mechanical arm 4 transports the waste plates of the die-cutting plates 3 after die-cutting to other areas, completing a round of die-cutting process. When the stamping parts descend and perform die-cutting on a plurality of stacked die-cutting sheets 3 from top to bottom, each die-cutting pad 11 will be respectively placed at the bottom of the plurality of die-cutting sheets 3, so that the upper and lower die-cutting sheets 3 will not contact each other, and the stamping parts will only apply force to a single die-cutting sheet 3 each time, and the pressure generated by die-cutting will only act on one die-cutting sheet 3, and then be transmitted to the long slide frame 9 and the short slide frame 10 on both sides through the die-cutting pad 11, so as to prevent the die-cutting sheet 3 that has not been die-cut at the bottom from being deformed and affecting the die-cutting accuracy, by setting a vibration plate 15, so that after the discharge frame 2 loaded with a plurality of die-cutting sheets 3 is placed on the vibration plate 15, the vibration motor inside the loading platform 1 will drive the vibration plate 15 to vibrate up and down, thereby driving the discharge frame 2 to vibrate up and down, so that the die-cutting sheets inside The materials 3 are separated from each other under the action of vibration, which effectively prevents the die-cutting plates 3 made of materials such as plastic and rubber from being squeezed and attached to each other under the action of gravity, affecting the transportation of the die-cutting plates 3 by the suction cup mechanical arm 4. By setting the positioning frame 16, when the discharge frame 2 is placed on the vibration plate 15, the positioning frame 16 can position the die-cutting plates 3, so that the discharge frame 2 remains in the same position each time it is placed, which facilitates the suction cup mechanical arm 4 to quickly grab the die-cutting plates 3 inside the discharge frame 2. At the same time, the positioning frame 16 will limit the bottom of the die-cutting plates 3, effectively preventing the die-cutting plates 3 from slipping on the top of the vibration plate 15 under the action of vibration when the vibration plate 15 drives the die-cutting plates 3 to vibrate up and down, affecting the positioning of the suction cup mechanical arm 4. By setting the lifting plate 17,When the suction cup mechanical arm 4 transfers the die-cutting sheet 3 at the top to the bottom of the stamping part of the die-cutting machine body 5, the lifting electric push rod inside the loading platform 1 will drive the lifting plate 17 to move upward, thereby making the lifting plate 17 pass through the lifting hole 201 and support the bottom of the die-cutting sheet 3 at the bottom, and then drive all the die-cutting sheets 3 to move up a unit distance as a whole, so that the die-cutting sheet 3 at the top is always kept at the same height, reducing the positioning time of the suction cup mechanical arm 4 and speeding up the grabbing and transportation of the die-cutting sheet 3. By setting the fastening bolts 22, each pad clamp 12 is fixedly connected to the die-cutting pad 11 by multiple fastening bolts 22, so that the pad clamp 12 and the die-cutting pad 11 are detachable structures, so as to facilitate the subsequent replacement of the die-cutting pad 11 in conjunction with the replacement of the stamping parts of the die-cutting machine body 5. By setting the limit baffle 18, the limit baffle 18 located on one side of the short sliding frame 10 can slide the die-cutting sheet 3 The maximum distance is limited to prevent the die-cutting plate 3 set between the long sliding frame 9 and the short sliding frame 10 from sliding excessively, which may cause the unloading slots 1102 on different die-cutting pads 11 to be unable to be positioned, thus affecting the downward movement of the stamping parts. By setting the laser locator 20 and the laser receiver 21, when the hydraulic press 13 controls the hydraulic rod 14 to drive each die-cutting pad 11 to be set between the long sliding frame 9 and the short sliding frame 10, the laser locator 20 will emit a positioning laser to the bottom, and it will be received by the laser receiver 21 at the bottom, and then the positioning detection of each die-cutting pad 11 after each setting is performed. When a die-cutting pad 11 fails to slide into place, the positioning slot 1103 on its top will be misaligned with all the positioning slots 1103 below, thereby blocking the laser and making the laser receiver 21 unable to receive it, thereby triggering an alarm, so that the laser locator 20 and the laser receiver 21 cooperate with each other to position the die-cutting pad 11.
