Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and in particular to the field of detecting defective products in die-cutting. Background Technology

[0002] Die-cut roll products are prone to carrying waste material after die-cutting, which needs to be detected and removed. The traditional method is manual visual inspection, which is inefficient, affects the production process, and is also prone to missed detection, affecting subsequent assembly and use. Summary of the Invention

[0003] The purpose of this invention is to provide a device for testing the inclusion of waste in die-cut roll products, which replaces manual labor and improves testing efficiency and accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for testing waste inclusions in die-cut roll products, comprising: The base, on which a reference platform is provided; The support frame is installed on the reference platform of the machine base and forms a material passage around the reference platform. The material passage allows the material to be tested to pass through, and the lower side of the material to be tested is flat against the reference platform. The contact displacement sensor is mounted on a support frame and partially extends into the material passage, so that the contact displacement sensor is vertically pressed against the upper side of the material to be detected. The contact displacement sensor detects the thickness of the material to be detected based on the undulation of the upper side of the material to be detected and outputs a signal. The controller is used to receive signals output by the contact displacement sensor and to alarm and shut down the system based on abnormal conditions.

[0005] Furthermore, the surface flatness of the reference platform is ≤0.05mm.

[0006] A further improvement in the above scheme is that the contact displacement sensor is an inductive sensor or a micrometer-type probe.

[0007] Furthermore, the above scheme includes a rubber roller on the reference platform, which is located downstream of the material feeding channel. The rubber roller is rotated by a servo motor, which enables the rubber roller to control the feeding speed of the material to be tested and to start and stop in case of abnormality. The rubber roller works with the reference platform to press the material coming out of the material feeding channel. The servo motor is connected to the controller.

[0008] A further provision of the above scheme is that a take-up roller is provided downstream of the rubber roller, and the take-up roller is controlled by a magnetic powder motor to control the take-up speed; a feed roller is provided upstream of the material passage, and the feed roller and the take-up roller form a roll-to-roll working system.

[0009] A further aspect of the above scheme is that the controller is a programmable logic controller.

[0010] The above scheme is further described as follows: the support frame has a support plate and support columns distributed at the four corners of the lower side of the support plate. The lower end of the support column is fixed to the reference platform, and the upper end of the support column supports the support plate, so that the support plate is set at a height so that a gap is left between the support plate and the reference platform to form a material passage. There are one or more contact displacement sensors. The contact displacement sensors are installed on the support plate and have a movement adjustment attribute. The direction of the material to be detected passing through the material passage is defined as the X-axis direction. Then the movement adjustment direction of the contact displacement sensor is the Y-axis direction, and the direction in which the contact displacement sensor perpendicularly presses against the material to be detected is the Z-axis direction.

[0011] A further improvement of the above scheme is that the rubber roller has an adjustable property to move closer to or further away from the reference platform in order to adapt to the detection of materials of different thicknesses.

[0012] This invention allows the material to be inspected to pass through a feeding channel, and through a precision reference platform and a high-precision contact displacement sensor, it achieves online full inspection of the thickness of die-cut roll products. It realizes automatic feeding, automatic positioning detection, automatic judgment, and automatic shutdown alarm for exceeding the standard. Manual intervention is only required after the alarm to remove defective products. It solves the problem of automated detection of "waste trapping" (localized thickening caused by foreign objects, multiple sheets of material, etc.) in die-cut products, improves product quality, and reduces the cost of manual sampling and the risk of missed inspections. Attached Figure Description

[0013] Appendix Figure 1 This is a schematic diagram of the principle structure of this utility model; Appendix Figure 2 This is a schematic diagram of one embodiment of the present utility model. Detailed Implementation

[0014] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0015] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0016] See Figure 1 , 2The diagram shown is a preferred embodiment of the present invention. The present invention relates to a device for testing the inclusion of waste in die-cut roll products, comprising: a base 1, a support frame 2, a contact displacement sensor 5, and a controller 6. The base is provided with a reference platform 11, the surface flatness of which is ≤0.05mm, providing a thickness measurement reference. The support frame 2 is mounted on the reference platform 11 of the base and together with the reference platform forms a material passage 3. This material passage 3 allows the material to be tested 4 to pass through, with the lower side of the material to be tested 4 flat against the reference platform 11. To further improve the transmission of the material to be tested 4 along the reference platform 11, a pressure roller can be added to the reference platform 11. The contact displacement sensor 5 is mounted on the support frame 2 and partially extends into the material passage 3, so that the contact displacement sensor 5 vertically presses against the upper side of the material to be tested 4. The contact displacement sensor 5 measures the thickness of the material to be tested based on the undulations of the upper side of the material to be tested 4 and outputs a signal. Preferably, the contact displacement sensor 5 is an inductive probe or a micrometer-type probe. The pressing end of the contact displacement sensor 5 forms a rolling contact with the material to be detected 4, which facilitates continuous movement detection of the material to be detected 4. The contact displacement sensor 5 has a resolution of 0.001mm, achieving high-precision measurement. The controller 6 is used to receive the signal output by the contact displacement sensor 5 and to alarm and stop the machine according to abnormal conditions. For ease of operation, the controller 6 is integrated with the base 1 through a mounting bracket. An alarm indicator light can also be added to improve practicality.

[0017] In this embodiment, a rubber roller 7 is also provided on the reference platform 11. This rubber roller is located downstream of the material feeding channel 3, and its rotation is controlled by a servo motor. This allows the rubber roller 7 to control the feeding speed and abnormal start / stop of the material to be tested 4. The rubber roller 7, in conjunction with the reference platform, presses the material exiting the material feeding channel 3, further improving the conveyance of the material to be tested 4 along the reference platform 11. Furthermore, the rubber roller 7 is mounted on an adjustment seat, giving it the ability to move closer to or further away from the reference platform, facilitating the detection of materials of different thicknesses. The servo motor is communicatively connected to the controller 6, enabling the controller 6 to output commands to the servo motor to control the rotation of the rubber roller 7. The servo motor precisely controls the material feeding, improving detection efficiency.

[0018] Downstream of the rubber roller 7 is a take-up roller 8, which controls the take-up speed via a magnetic powder motor; upstream of the material passage 3 is a discharge roller 9, which forms a roll-to-roll working system with the take-up roller 8 to achieve continuous detection; the take-up roller 8 actively pulls and controls the speed, while the discharge roller 9 passively rotates to control the discharge tension, which facilitates the transmission of the material to be tested 4 along the reference platform 11, ensuring that the material is stable and vibration-free during the detection process.

[0019] The controller 6 is a mature existing programmable logic controller, which has a receiving section, a comparison and analysis section, and a signal output control section. It has a simple structure, low investment cost, and is easy to operate. The operator only needs to input parameters such as the feeding speed, the winding speed, and the lower and upper limits of the thickness of the material 4 to be tested.

[0020] The support frame 2 has a support plate 21 and support columns 22 distributed at the four corners of the lower side of the support plate. The lower end of the support column 22 is fixed on the reference platform 11, and the upper end of the support column 22 supports the support plate, so that the support plate is set at a height, leaving a gap between the support plate and the reference platform to form a material passage channel 3. There are one or more contact displacement sensors 5. The contact displacement sensor 5 is installed on the support plate 21 and has a movement adjustment attribute. If the direction of the material to be detected 4 passing through the material passage 3 is defined as the X-axis direction, then the movement adjustment direction of the contact displacement sensor 5 is the Y-axis direction, and the direction in which the contact displacement sensor 5 presses against the material to be detected 4 perpendicularly is the Z-axis direction. Furthermore, a mounting groove extending in the Y-axis direction is provided on the support plate 21. The contact displacement sensor 5 is embedded in the mounting groove and fixed by means of screw locking or snap connection, so that the contact end of the contact displacement sensor 5 protrudes vertically downward and can press vertically against the upper side of the material to be detected 4. The contact end of the contact displacement sensor 5 is appropriately provided with ball bearings for rolling contact with the material to be detected 4, so as to satisfy the continuous motion transmission of the material to be detected 4.

[0021] During operation, the feed speed, winding speed, and the lower and upper limits of the thickness of the material to be tested are input into the controller 6. Then, the material to be tested (in roll) whose thickness needs to be tested is placed on the feed roller 9. When the material to be tested is pulled and passes through the material passage 3, the contact displacement sensor 5 presses vertically against the upper side of the material to be tested 4. The roller presses and detects the thickness of the material to be tested 4. The rubber roller presses on the material coming out of the material passage 3, controlling the feed speed and abnormal start and stop. After the thickness is tested, the material without abnormalities is wound by the take-up roller 8. When the thickness is detected to exceed the lower limit, it means there is insufficient material. When the thickness is detected to exceed the upper limit, it means there is waste. The machine will alarm and stop. After the defective products are manually removed, the machine's start button is pressed, and the equipment continues to move normally.

[0022] This invention provides a 100% inspection of continuously fed die-cut roll products, ensuring that each product undergoes thickness measurement. Thickness tolerance exceedance judgment: A thickness tolerance standard is set (e.g., ±10%), and the system judges in real time whether the product thickness exceeds the allowable range. When a defective product with excessive thickness is detected, the equipment immediately and automatically stops, triggering an alarm device (audible, visual, etc.). After stopping, the operator locates and removes the defective product.

[0023] Closed-loop control: The contact displacement sensor 5 transmits the real-time thickness signal to the controller 6. The controller 6 compares the measured value with the preset tolerance (such as ±10%) and then outputs the control: if the thickness is within the tolerance, the equipment continues to operate; if the thickness exceeds the standard, a stop signal is immediately sent to the servo motor and magnetic powder motor to stop the material feeding and tension system, and at the same time trigger the alarm.

[0024] This invention allows the material to be inspected to pass through a feeding channel, and through a precision reference platform and a high-precision contact displacement sensor, it achieves online full inspection of the thickness of die-cut roll products. It realizes automatic feeding, automatic positioning detection, automatic judgment, and automatic shutdown alarm for exceeding the standard. Manual intervention is only required after the alarm to remove defective products. It solves the problem of automated detection of "waste trapping" (localized thickening caused by foreign objects, multiple sheets of material, etc.) in die-cut products, improves product quality, and reduces the cost of manual sampling and the risk of missed inspections.

[0025] This invention can accurately measure product thickness (accuracy 0.001mm) and determine product quality in real time based on a set thickness tolerance (e.g., ±10%). If a thickness exceeding the tolerance is detected (resulting in defective products), the equipment will automatically stop and alarm, prompting manual replacement of the defective product, thus effectively ensuring product quality and preventing defective products from leaving the site.
