Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and more specifically, to an alignment and correction structure for a precision die-cutting machine. Background Technology

[0002] In today's manufacturing industry, which constantly pursues high-precision and high-quality products, precision die-cutting technology, as a key processing method, has been widely used in many fields. For example, in the electronics field, various precision components inside electronic products such as mobile phones and tablets, including flexible circuit boards, sensor pads, and insulating materials, require precision die-cutting to obtain accurate shapes and dimensions to meet the demands of miniaturization and high performance in electronic products. In the optics field, the die-cutting of protective films and light-shielding plates for optical lenses requires extremely high precision, directly affecting the imaging quality of optical products. Precision die-cutting operations are typically performed on corresponding precision die-cutting machines.

[0003] Utility model patent CN212331146U discloses a fully automatic precision die-cutting machine, including a support plate. A second motor is fixedly installed on the top left side of the support plate, and an active guide mechanism is fixedly installed on the front output end of the second motor. A driven guide mechanism is fixedly installed on the top right side of the support plate. Support frames are fixedly installed on both the top left and right sides of the support plate, with two sets of support frames respectively positioned between the active and driven guide mechanisms. Motor housings are fixedly installed on the top of the two sets of support frames. A mounting groove is provided on the side of the two motor housings that are close to each other. A first motor is fixedly installed on the top of the inner cavity of the two sets of motor housings, and a threaded mechanism that rotatably connects to the bottom of the inner cavity of the motor housing is fixedly installed on the bottom output end of the two sets of first motors. This fully automatic precision die-cutting machine uses a timer relay to set different durations and timely control the second motor to turn off and the first motor to drive the die-cutting plate and die-cutting blade to move downwards synchronously to cut materials of different fixed lengths.

[0004] While this technical solution offers the advantage of cutting materials to various fixed lengths, most current precision die-cutting machines rely on cylinders to move the corresponding clamping parts downwards, pressing the raw material sheet onto the corresponding processing table for stable clamping and positioning. However, when using cylinders for positioning, the placement of the raw material sheet must be accurate. Any deviation in position, especially without corresponding alignment and correction components, will cause the raw material sheet to shift, affecting the accuracy of subsequent die-cutting processes. Therefore, we propose an alignment and correction structure for precision die-cutting machines. Utility Model Content

[0005] The purpose of this invention is to provide an alignment and correction structure for a precision die-cutting machine to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The alignment and correction structure of a precision die-cutting machine includes a die-cutting machine body and a processing panel mounted on the die-cutting machine body. One end of the processing panel is provided with a front and rear calibration component for correcting the left and right positions of the raw material. The front and rear calibration component includes a guide rail, in which two symmetrical sliders are slidably connected. The two sliders are driven by a servo motor and a lead screw and move in opposite directions. A vertically arranged long shaft is fixedly mounted on the top surface of the slider, and a vertically arranged calibration roller is rotatably connected to the long shaft. The other end of the processing panel is provided with an end calibration component for limiting the end of the raw material. The end calibration component includes a horizontally arranged first cylinder and a second cylinder vertically mounted on the telescopic shaft of the first cylinder. The end of the telescopic shaft of the second cylinder is detachably connected to an abutment plate.

[0008] Preferably, the two sides of the raw material plate abut against the two calibration rollers respectively, and the end of the raw material plate abuts against the side of the abutment plate for alignment and correction operation.

[0009] Preferably, a plurality of fixing protrusions are fixedly installed on the guide rail, and the fixing protrusions are detachably installed on the processing panel.

[0010] Preferably, the guide rail is provided with a sliding groove arranged along the length of the guide rail, and the slider is located in the sliding groove and is slidably connected to the sliding groove;

[0011] This setting makes the slider move more stably and smoothly.

[0012] Preferably, a forward lead screw is fixedly installed at the end of the output shaft of the servo motor, and a reverse lead screw is fixedly installed at the end of the forward lead screw. Both the forward lead screw and the reverse lead screw pass through the corresponding slider and are threadedly connected to the slider.

[0013] This setting allows the two sliders to move in opposite directions, effectively calibrating sheet materials of different sizes in the front-to-back direction.

[0014] Preferably, the end plate of the processing panel is provided with a sliding hole, the first cylinder is fixedly installed on the bottom surface of the processing panel, and the abutment plate extends out from the sliding hole and is slidably connected to the sliding hole.

[0015] Preferably, a steel plate is fixedly installed at the end of the telescopic shaft of the first cylinder, a slide block is fixedly installed on the side of the steel plate, a groove is provided in the slide block, the second cylinder is fixedly installed on the bottom wall of the groove, a support plate is fixedly installed at the end of the telescopic shaft of the second cylinder, a fixing seat is fixedly installed at the bottom end of the abutment plate, and the fixing seat is detachably installed on the upper surface of the support plate.

[0016] Preferably, the end plate of the processing panel is provided with two symmetrical guide holes on the left and right sides, the ends of the guide holes are connected to the outside, and guide blocks are fixedly installed on the top surfaces of the left and right side plates of the slide block, the guide blocks are located in the guide holes and are slidably connected to the guide holes.

[0017] The above two settings enable the slide to move stably, and at the same time make the up-and-down movement of the abutment plate driven by the second cylinder more stable.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting up front and rear calibration components and end calibration components, uses a servo motor to drive the lead screw to move the slider and calibration roller. The position can be flexibly adjusted according to the size of the raw material sheet, so that both sides of the raw material sheet are accurately abutted against the calibration roller. At the same time, the first cylinder and the second cylinder work together to drive the abutment plate to move, thereby limiting the end of the raw material sheet. This achieves precise alignment and correction of the raw material sheet from all directions, thereby improving the positioning accuracy of the raw material sheet and ensuring the precision of die-cutting processing.

[0020] 2. This utility model features a fixed protrusion on the guide rail, which facilitates installation on the processing panel. The groove design inside the guide rail ensures stable movement of the slider. The servo motor connects the forward lead screw and the reverse lead screw, which can drive the two sliders to move in opposite directions. This enables rapid adaptation and calibration of raw materials of different sizes, thereby enhancing the versatility and stability of the alignment and correction structure.

[0021] 3. This utility model, through the combination structure of the first cylinder and the second cylinder, and the cooperation of the slide block and the guide block, and the sliding hole and the guide hole on the processing panel, makes the movement of the abutment plate more stable and smooth in the horizontal and vertical directions, and achieves precise and stable abutment and limiting of the end of the raw material plate, thereby further improving the alignment and correction accuracy and reducing the generation of waste products due to plate position deviation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: a alignment and correction structure for a precision die-cutting machine, including a die-cutting machine body 1 and a processing panel 10 disposed on the die-cutting machine body 1. One end of the processing panel 10 is provided with a front and rear calibration component 2 for correcting the left and right positions of the raw material. The front and rear calibration component 2 includes a guide rail 20, within which two symmetrical sliders 25 are slidably connected. The two sliders 25 are driven by a servo motor 22 and a lead screw and move in opposite directions. A vertically arranged long shaft 26 is fixedly mounted on the top surface of the sliders 25, and a vertically arranged calibration roller 27 is rotatably connected to the long shaft 26. The guide rail 20 is provided with a groove 21 along the length of the guide rail 20. The slider 25 is located in the groove 21 and is slidably connected to the groove 21. The output shaft of the servo motor 22 is fixedly installed with a forward lead screw 23 and a reverse lead screw 24. Both the forward lead screw 23 and the reverse lead screw 24 pass through the corresponding slider 25 and are threadedly connected to the slider 25, so that the two sliders 25 can move in opposite directions, driving the calibration roller 27 to adjust its position. The left and right positions can be accurately calibrated according to the width of the raw material plate, realizing the rapid adaptation of plates of different sizes and improving the left and right positioning accuracy of the raw material plate.

[0033] In this embodiment, the other end of the processing panel 10 is provided with an end calibration component 3 for limiting the end of the raw material. The end calibration component 3 includes a first cylinder 30 arranged horizontally and a second cylinder 34 mounted vertically on the telescopic shaft of the first cylinder 30. The end of the telescopic shaft of the second cylinder 34 is detachably connected to an abutment plate 35. The two sides of the raw material plate abut against two calibration rollers 27 respectively, and the end of the raw material plate abuts against the side of the abutment plate 35 for alignment and correction operation.

[0034] like Figures 1-3 As shown, multiple fixing protrusions 201 are fixedly installed on the guide rail 20. The fixing protrusions 201 are detachably installed on the processing panel 10 by multiple fastening screws, which facilitates the fixing, installation and removal of the guide rail 20.

[0035] Specifically, a sliding hole 11 is provided on the end plate of the processing panel 10. The first cylinder 30 is fixedly installed on the bottom surface of the processing panel 10. The abutment plate 35 passes through the sliding hole 11 and slides between it and the sliding hole 11, so that the abutment plate 35 can move up and down normally. When the abutment plate 35 extends out of the sliding hole 11, the raw material plate can abut against the side of the abutment plate 35 for limiting operation. When the abutment plate 35 is retracted into the sliding hole 11, there is no obstruction component at the end of the raw material plate. At this time, the raw material plate can be conveyed forward normally.

[0036] Furthermore, a steel plate 301 is fixedly installed at the end of the telescopic shaft of the first cylinder 30. A slide block 31 is detachably installed on the side of the steel plate 301 by multiple fastening bolts. A groove 32 is provided in the slide block 31. The second cylinder 34 is fixedly installed on the bottom wall of the groove 32, thereby providing installation space for the second cylinder 34. A support plate 341 is fixedly installed at the end of the telescopic shaft of the second cylinder 34. A fixing seat 351 is fixedly installed at the bottom end of the abutment plate 35. The fixing seat 351 is detachably installed on the upper surface of the support plate 341 by multiple fastening screws, which facilitates the fixing, installation, disassembly and replacement of the abutment plate 35.

[0037] It is worth noting that the end plate of the processing panel 10 is provided with two symmetrical guide holes 12 on the left and right sides. The ends of the guide holes 12 are connected to the outside. Guide blocks 33 are fixedly installed on the top surfaces of the left and right side plates of the slide block 31. The guide blocks 33 are located in the guide holes 12 and are slidably connected to the guide holes 12, so that the slide block 31 can move stably. At the same time, the second cylinder 34 drives the abutment plate 35 to move up and down more stably.

[0038] It is worth noting that the rotatable connection between the calibration roller 27 and the long shaft 26 can reduce friction, so that after the subsequent calibration roller 27 abuts against the side of the sheet material, the sheet material can still be pushed forward to abut against the side of the abutment plate 35 for end calibration operation.

[0039] Finally, it should be noted that the servo motor 22, the first cylinder 30, and the second cylinder 34 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0040] When using the alignment and correction structure of the precision die-cutting machine of this utility model, the sheet material is placed between two calibration rollers 27, the servo motor 22 is started, which drives the forward lead screw 23 and the reverse lead screw 24 to rotate, so that the two sliders 25 slide in opposite directions in the groove 21 in the guide rail 20, and the position of the calibration rollers 27 is adjusted to match the width of the raw material sheet material, so that the two sides of the raw material sheet material abut against the calibration rollers 27 respectively, thus completing the left and right position correction;

[0041] Subsequently, the first cylinder 30 extends, driving the slide block 31 and guide block 33 to move horizontally along the guide hole 12, adjusting the position of the abutment plate 35. Then the second cylinder 34 works, driving the abutment plate 35 to extend from the slide hole 11, pressing and limiting the end of the raw material plate, thereby limiting the front and rear sides and the end of the raw material plate.

[0042] When die-cutting is complete and a new raw material sheet needs to be transported, the second cylinder 34 retracts, and the abutment plate 35 is stored in the sliding hole 11, making room for the transport of the raw material sheet.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
