Description

Technical Field

[0001] This invention relates to the field of waste removal die-cutting machine technology, and in particular to a packaging printing waste removal die-cutting machine based on artificial intelligence. Background Technology

[0002] In existing technology, die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. Die-cutting machines utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. They are crucial equipment for post-printing packaging processing. However, die-cutting often generates waste material, requiring a waste removal mechanism to clean it up.

[0003] Chinese Patent Publication No. CN113427553A discloses a novel two-frame waste-removing die-cutting machine and its usage method, comprising: a frame, a first waste-removing mechanism, and a second waste-removing mechanism. A waste-removing gantry and a waste-removing support column are sequentially fixed to the top of the frame along the material conveying direction. The first waste-removing mechanism is mounted on the waste-removing gantry, and a first lower template is positioned directly below the first waste-removing mechanism. The second waste-removing mechanism is mounted on the waste-removing support column, and a second lower template is positioned directly below the second waste-removing mechanism. This invention performs primary waste removal through the first waste-removing mechanism, and then uses a camera to capture images to determine whether waste removal is complete at each die-cutting position. Based on the images, the second waste-removing mechanism at the corresponding position is activated. The two-frame waste-removing design improves the waste removal effect of the die-cutting machine, increases energy efficiency, and allows for cleaning of dust generated at the die-cutting position via a rigid air supply pipe. This solves the problems of high energy consumption and limited waste removal methods in existing die-cutting machines. Therefore, it can be seen that the novel two-frame waste removal die-cutting machine and its usage method have the problem that the waste is difficult to be adsorbed onto the brush due to the poor adsorption capacity of the brush, resulting in the waste being distributed on the die-cut product and thus the waste removal of the die-cut product is not thorough. Summary of the Invention

[0004] To address this issue, the present invention provides an artificial intelligence-based packaging printing waste removal and die-cutting machine, which overcomes the problem in the prior art where the poor adsorption capacity of the brush makes it difficult for waste to be adsorbed onto the brush, resulting in waste being distributed on the die-cut product and thus incomplete waste removal from the die-cut product.

[0005] To achieve the above objectives, the present invention provides an artificial intelligence-based packaging printing waste removal die-cutting machine, comprising: a die-cutting mechanism for performing corresponding die-cutting operations on the product to be die-cut to output a basic die-cut product;

[0006] A conveying mechanism, which is located at the output end of the die-cutting mechanism, includes an input roller set and an output roller set that cooperate with each other to convey the basic die-cut product to the position to be cleared.

[0007] A cleaning mechanism, disposed above the conveying mechanism, is used to remove waste material attached to the base die-cut product to output the target die-cut product. The mechanism includes a brush, a vertical moving element connected to the brush to determine the vertical distance between the brush and the base die-cut product based on the width of the brush and the width of the waste distribution on the surface of the base die-cut product, a horizontal moving element connected to the vertical moving element to determine the horizontal distance between the brush and the input roller group based on the change in the waste distribution area on the surface of the base die-cut product, and an image sensor disposed above the brush to acquire an image of the surface of the base die-cut product.

[0008] A control mechanism, which is connected to the die-cutting mechanism, the conveying mechanism and the cleaning mechanism respectively, is used to correct the width of the brush based on the width of the waste distribution on the surface of the base die-cut product in a single cycle of the brush's first use, and to redetermine the vertical distance between the brush and the base die-cut product based on the change in the projected area of ​​the waste.

[0009] Furthermore, the vertical moving element includes:

[0010] A lead screw, on which a lead screw nut connected to the brush is fitted;

[0011] The first stepper motor is connected to the lead screw and is used to drive the lead screw to rotate;

[0012] The guide rod, which is connected to the brush via a collar, is used to constrain the running trajectory of the brush.

[0013] Furthermore, the horizontal moving element includes:

[0014] A timing belt is positioned above the first stepper motor;

[0015] A second stepper motor is connected to the synchronous belt to drive the synchronous belt to move;

[0016] A slider, which is fixedly connected to the timing belt, is used to drive the vertical moving element to move;

[0017] A guide rail, which is connected to the slider, is used to constrain the horizontal movement direction of the slider.

[0018] Furthermore, the input roller group and the output roller group respectively include an input active roller, an input driven roller disposed above the input active roller, an output active roller disposed on the side away from the base die-cut product where the input active roller is located, and an output driven roller disposed above the output active roller.

[0019] Furthermore, a horizontal support is provided above the guide rail to fix the spatial position of the guide rail, and an input end pressing rod for pressing down the input end driven roller / output end pressing rod for pressing down the output end driven roller is provided between the input end driven roller / output end pressing roller and the horizontal support.

[0020] Furthermore, the control mechanism is used to obtain the width of the brush and the width of the waste distribution on the surface of the basic die-cut product. If the absolute value of the difference between the width of the brush and the width of the waste distribution on the surface of the basic die-cut product is less than or equal to a preset difference, it is determined to be an adsorption type fault, and the vertical distance between the brush and the basic die-cut product is reduced.

[0021] Furthermore, the vertical distance between the brush and the base die-cut product is positively correlated with the absolute value of the difference between the width of the brush and the width of the waste distribution on the surface of the base die-cut product.

[0022] Furthermore, the control mechanism is used to obtain the waste distribution area of ​​the set sampling area on the surface of the basic die-cut product under the set sampling period, and determine the scattered type fault based on the change of the waste distribution area being greater than the preset change of the waste distribution area, and reduce the horizontal distance between the brush and the input end roller group.

[0023] Furthermore, the width of the brush is corrected to the width of the brush minus the width of the waste distribution on the surface of the base die-cut product during the first single cycle of brush use.

[0024] Furthermore, the control mechanism is connected to the image sensor and the vertical moving element respectively, and is used to perform several samplings of the waste projection area at a preset sampling interval when the vertical moving element determines that the absolute value of the difference between the width of the brush and the width of the waste distribution on the surface of the basic die-cut product is less than or equal to a preset difference as an adsorption type fault, and reduces the vertical distance between the brush and the basic die-cut product. Based on the condition that the change in the waste projection area at the preset sampling interval is greater than the preset change in the waste projection area, the vertical distance between the brush and the basic die-cut product is increased.

[0025] Compared with the prior art, the beneficial effect of the present invention is that the control mechanism determines that the brush's adsorption capacity for waste is insufficient, causing the waste on the surface of the basic die-cut product to be pushed away by the brush, based on the absolute value of the difference between the width of the brush and the width of the waste distribution on the surface of the basic die-cut product being less than or equal to a preset difference. This results in the brush pushing the waste on the surface of the basic die-cut product away. If the width of the waste distribution on the surface of the basic die-cut product matches the width and height of the brush, it is determined to be an adsorption-type fault. The vertical moving element is then controlled to reduce the vertical distance between the brush and the basic die-cut product. This solves the problem that when the brush's adsorption capacity for waste is insufficient, only a small amount of waste is concentrated near the brush on the part of the basic die-cut product, while most waste remains attached to the surface of the basic die-cut product, resulting in low waste removal efficiency. By reducing the vertical distance between the brush and the basic die-cut product, more waste attached to the basic die-cut product can enter the part of the brush away from the basic die-cut product, thus improving the brush's adsorption capacity for waste.

[0026] Furthermore, the control mechanism determines that the waste distribution area change is greater than the preset waste distribution area change as a scattered fault, and controls the horizontal moving element to reduce the horizontal distance between the brush and the input end roller group. This invention addresses the problem that when the input roller assembly operates for extended periods, the increased heat leads to an increase in the volume of both the input active and driven rollers, resulting in a smaller distance between them. This increased pressure on the base die-cut product causes waste material adhering to the product surface to more easily adhere to the driven rollers. When the driven rollers rotate, this waste material tends to splash onto the brush, and due to vibration, it scatters onto the base die-cut product surface, affecting the efficiency of the waste removal mechanism. By reducing the horizontal distance between the brush and the input roller assembly, the probability of waste material adhering to the driven rollers splashing onto the brush during rotation is reduced, thus decreasing the likelihood of waste material scattering onto the base die-cut product surface and improving the efficiency of the waste removal mechanism.

[0027] Furthermore, the control mechanism determines to increase the vertical distance between the brush and the basic die-cut product based on the fact that the change in the projected area of ​​the waste material under the preset sampling interval is greater than the preset change in the projected area of ​​the waste material. This solves the problem that when the brush removes the waste material from the surface of the basic die-cut product, the waste material is easily lifted up, and the lifted waste material will interfere with the image sensor's image acquisition, thus improving the accuracy of the image sensor's image acquisition.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Please see Figure 1 , Figure 2 as well as Figure 3The figures shown are a schematic diagram, a block diagram, and a block diagram of the conveying mechanism of the packaging printing waste removal and die-cutting machine based on artificial intelligence according to an embodiment of the present invention. The packaging printing waste removal and die-cutting machine based on artificial intelligence according to an embodiment of the present invention includes:

[0038] Die-cutting mechanism, used to perform corresponding die-cutting operations on the product to be die-cut to output basic die-cut product 3, including die-cutting head 1;

[0039] In practice, the optional types of basic die-cutting product 3 are paper, plastic, rubber, foam, tape, and self-adhesive. Among them, the waste removal effect of paper as the basic die-cutting product 3 is better in the packaging and printing waste removal die-cutting machine based on artificial intelligence.

[0040] A conveying mechanism, which is located at the output end of the die-cutting mechanism, includes an input roller group and an output roller group that cooperate with each other to convey the basic die-cut product 3 to the position to be cleared.

[0041] A cleaning mechanism, disposed above the conveying mechanism, is used to remove waste material attached to the base die-cut product 3 to output the target die-cut product. The mechanism includes a brush 2, a vertical moving element connected to the brush 2 to determine the vertical distance between the brush 2 and the base die-cut product 3 based on the width of the brush 2 and the width of the waste distribution on the surface of the base die-cut product 3, a horizontal moving element connected to the vertical moving element to determine the horizontal distance between the brush 2 and the input roller group based on the change in the waste distribution area on the surface of the base die-cut product 3, and an image sensor 4 disposed above the brush 2 to acquire images of the surface of the base die-cut product 3.

[0042] In practice, when the thickness of the basic die-cut product 3 is between 0.1mm and 5mm, the brush 2 can be either a fixed brush or a roller brush, with the preferred embodiment being a roller brush. Those skilled in the art can make adaptive adjustments or replacements to the type of brush 2 according to the actual application scenario or implementation environment.

[0043] Among them, the bristles of the fixed brush are arranged on the side close to the base die-cut product 3. The fixed brush scrapes off the waste material on the surface of the base die-cut product 3 by relative movement with the base die-cut product 3 moving under the drive of the conveying mechanism; the roller brush removes the waste material on the surface of the base die-cut product 3 moving under the drive of the conveying mechanism by rotating the bristles arranged on its peripheral side.

[0044] A control mechanism, which is connected to the die-cutting mechanism, the conveying mechanism and the cleaning mechanism respectively, is used to correct the width of the brush 2 based on the width of the waste distribution on the surface of the base die-cut product 3 in a single cycle of the brush 2's first use, and to redetermine the vertical distance between the brush 2 and the base die-cut product 3 based on the change in the waste projection area.

[0045] Specifically, the die-cutting machine in this embodiment is also equipped with an air jet mechanism, which is located between the die-cutting mechanism and the conveying mechanism, for the initial stripping of the waste material connected to the edge of the basic die-cut product 3. The air jet mechanism includes a high-pressure air pump, an air tank and an air pipeline, as well as nozzles located around the die-cutting mechanism.

[0046] Specifically, the gas in the gas storage tank is pressurized by the high-pressure air pump to form a high-pressure airflow. This high-pressure airflow is directionally sprayed through the nozzle and acts on the edge of the basic die-cut product 3 instantly after the die-cutting mechanism has finished working. The waste material is peeled off from the basic die-cut product 3 by using the air pressure difference.

[0047] In practice, when the thickness of the basic die-cut product 3 is between 0.1mm and 5mm, the optional types of the jet mechanism are dynamic air curtain type jet structure, modular multi-nozzle array, and directional jet type jet structure. The preferred implementation is modular multi-nozzle array. Those skilled in the art can make adaptive adjustments or replacements to the type of jet mechanism according to the actual application scenario or implementation environment.

[0048] Specifically, the dynamic air curtain jet structure adopts an annular / cross airflow design, forming a covering air curtain through multiple sets of nozzles distributed around the die-cutting station to preferentially peel off edge waste; the modular multi-nozzle array consists of 6-16 nozzles with adjustable spacing (50mm-100mm), supporting the switching of fan-shaped or conical airflow modes to cover different positions in the die-cutting area; the directional jet jet structure is designed for specific waste areas (such as sharp corners and narrow slits), using focusing nozzles or right-angle airflow ducts to achieve high-precision local peeling.

[0049] Specifically, the single cycle refers to the complete release of static electricity generated during the first friction between the brush 2 and the base die-cut product 3 in that cycle.

[0050] Optionally, when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the single cycle can be selected from [1min, 2min].

[0051] Preferably, in this embodiment, when the cleaning mechanism is operating at a temperature of 15℃ to 30℃ and a humidity of 40% to 60%, the preferred embodiment of a single cycle is 1 minute.

[0052] Those skilled in the art will understand that the preferred setting of 1 minute is a preferred embodiment when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to this single cycle according to the changes in temperature and humidity conditions of the cleaning mechanism.

[0053] Specifically, the vertical moving element includes:

[0054] A lead screw 5, on which a lead screw nut 6 connected to the brush 2 is fitted;

[0055] The first stepper motor 7 is connected to the lead screw 5 and is used to drive the lead screw 5 to rotate;

[0056] The guide rod 8 is connected to the brush 2 via a collar 9 to constrain the running trajectory of the brush 2.

[0057] In implementation, the vertical moving element can be an electric push rod, a pneumatic / hydraulic cylinder, or a lead screw 5 (and a first stepper motor 7, a guide rod 8, and a lead screw nut 6 that cooperate with it). The preferred implementation is the lead screw 5 (and a first stepper motor 7, a guide rod 8, and a lead screw nut 6 that cooperate with it). Those skilled in the art can make adaptive adjustments or replacements to the type of vertical moving element according to the actual application scenario or implementation environment.

[0058] Specifically, the horizontal moving element includes:

[0059] Synchronous belt 11 is positioned above the first stepper motor 7;

[0060] The second stepper motor is connected to the synchronous belt 11 to drive the synchronous belt 11 to move;

[0061] The slider 12 is fixedly connected to the timing belt 11 and is used to drive the vertical moving element to move.

[0062] The guide rail 13 is connected to the slider 12 and is used to constrain the horizontal movement direction of the slider 12.

[0063] In implementation, the optional types of horizontal moving elements are electric push rods, pneumatic / hydraulic cylinders, and synchronous belts 11 (and their cooperating second stepper motors, sliders 12, and guide rails 13). The preferred embodiment is synchronous belts 11 (and their cooperating second stepper motors, sliders 12, and guide rails 13). Those skilled in the art can make adaptive adjustments or replacements to the type of horizontal moving elements according to the actual application scenario or implementation environment.

[0064] Specifically, the input roller group and the output roller group respectively include an input active roller 14, an input driven roller 15 disposed above the input active roller 14, an output active roller 16 disposed on the side away from the base die-cut product 3 where the input active roller 14 is located, and an output driven roller 17 disposed above the output active roller 16.

[0065] Specifically, a horizontal support 10 is fixedly connected to the guide rail 13 and positioned above the guide rail 13 to fix the spatial position of the guide rail 13. Between the input driven roller 15 / output driven roller 17 and the horizontal support 10, there is an input end pressing rod 18 for pressing down the input end driven roller 15 and an output end pressing rod 19 for pressing down the output end driven roller 17.

[0066] Specifically, the control mechanism is used to obtain the width of the brush 2 and the width of the waste distribution on the surface of the basic die-cut product 3. If the absolute value of the difference between the width of the brush 2 and the width of the waste distribution on the surface of the basic die-cut product 3 is less than or equal to a preset difference, it is determined to be an adsorption type fault, and the vertical distance between the brush 2 and the basic die-cut product 3 is reduced.

[0067] In implementation, the control mechanism determines that the brush 2's ability to adsorb waste is insufficient if the absolute value of the difference between the width of the brush 2 and the width of the waste distribution on the surface of the base die-cut product 3 is less than or equal to a preset difference. This causes the waste on the surface of the base die-cut product 3 to be pushed away by the brush 2. If the width of the waste distribution on the surface of the base die-cut product 3 matches the width and height of the brush 2, it is determined to be an adsorption-type fault. The control mechanism then controls the vertical moving element to reduce the vertical distance between the brush 2 and the base die-cut product 3. This solves the problem that when the brush 2's ability to adsorb waste is insufficient, only a small amount of waste is concentrated near the base die-cut product 3, while most waste remains attached to the surface of the base die-cut product 3, resulting in low waste removal efficiency. By reducing the vertical distance between the brush 2 and the base die-cut product 3, more waste attached to the base die-cut product 3 can enter the part of the brush 2 away from the base die-cut product 3, thus improving the brush 2's ability to adsorb waste.

[0068] Optionally, when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preset difference can be selected within the range of [3.8mm, 5.5mm].

[0069] Preferably, in this embodiment, when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preferred embodiment of the preset difference is 4.5mm.

[0070] Those skilled in the art will understand that the preferred setting of 4.5mm is a preferred embodiment when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to this preset difference according to the changes in the temperature and humidity conditions of the cleaning mechanism.

[0071] During implementation, when the cleaning mechanism is under conditions of temperature: 15℃~30℃ and humidity: 40%~60%, when the absolute value of the difference between the width of brush 2 and the width of the waste distribution on the surface of the base die-cut product 3 is less than 1mm below the preset difference, the vertical moving element adjusts the vertical distance between brush 2 and the base die-cut product 3 to 0.85 times the current vertical distance between brush 2 and the base die-cut product 3; when the absolute value of the difference between the width of brush 2 and the width of the waste distribution on the surface of the base die-cut product 3 is less than the preset difference, the vertical moving element adjusts the vertical distance between brush 2 and the base die-cut product 3 to 0.85 times the current vertical distance between brush 2 and the base die-cut product 3. If the difference exceeds 1mm, the vertical distance between the brush 2 and the base die-cut product 3 will be reduced to 0.85 times the original value for every 1mm exceeding the original value. For example, in one possible embodiment, the absolute value of the difference between the width of the brush 2 and the width of the waste distribution on the surface of the base die-cut product 3 is less than the preset difference value of 2mm. When it exceeds 1mm, the part exceeding 1mm is calculated by rounding. At this time, the vertical distance between the brush 2 and the base die-cut product 3 will be reduced to 0.85 × 0.85 = 0.7225 times the original value.

[0072] Specifically, the vertical distance between the brush 2 and the basic die-cut product 3 is positively correlated with the absolute value of the difference between the width of the brush 2 and the width of the waste distribution on the surface of the basic die-cut product 3.

[0073] Specifically, the control mechanism is used to obtain the waste distribution area of ​​the set sampling area on the surface of the basic die-cut product 3 under the set sampling period, and determine the scattered type fault based on the change of the waste distribution area being greater than the preset waste distribution area change, and reduce the horizontal distance between the brush 2 and the input end roller group.

[0074] Optionally, when the cleaning mechanism is under conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the selectable range of the sampling area can be set to [25cm]. 2 36cm 2 ].

[0075] Preferably, in this embodiment, when the cleaning mechanism is under conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preferred embodiment for setting the sampling area is 30cm. 2 .

[0076] As will be understood by those skilled in the art, 30cm 2 The preferred embodiment is when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the set sampling area according to the changes in temperature and humidity conditions of the cleaning mechanism.

[0077] During implementation, when the cleaning mechanism is under conditions of temperature 15℃~30℃ and humidity 40%~60%, if the change in waste distribution area exceeds the preset value for waste distribution area change by more than 1cm... 2 When the horizontal moving element adjusts the horizontal distance between brush 2 and the input roller group to 0.9 times the current horizontal distance between brush 2 and the input roller group, the horizontal movement element will adjust the horizontal distance between brush 2 and the input roller group to 0.9 times the current horizontal distance between brush 2 and the input roller group. When the change in waste distribution area exceeds the preset value of waste distribution area change by more than 1 cm... 2 At that time, for every 1cm exceeding 2 The horizontal distance between brush 2 and the input roller assembly is reduced to 0.9 times its original value; for example, in one possible embodiment, the change in waste distribution area exceeds the preset waste distribution area change by 2.6 cm. 2 Among them, when it exceeds 1cm 2 When the value exceeds 1cm according to rounding, 2 In this part, the horizontal distance between brush 2 and the input end roller group is reduced to 0.9×0.9×0.9=0.729 times the original value.

[0078] Optionally, when the cleaning mechanism is under conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preset range for the change in waste distribution area is [2.5cm]. 2 3.6cm 2 ].

[0079] Preferably, in this embodiment, when the cleaning mechanism is under conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preferred embodiment of the preset waste distribution area change is 3cm. 2 .

[0080] As will be understood by those skilled in the art, 3cm 2 The preferred embodiment is when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the preset waste distribution area according to the changes in temperature and humidity conditions of the cleaning mechanism.

[0081] Specifically, the width of brush 2 is corrected to the width of brush 2 minus the width of the waste distribution on the surface of the base die-cut product 3 during the first single cycle of brush 2's use. Before correction, the width of the brush refers to its total capacity to adsorb waste. The width of the brush under non-electrostatic conditions is replaced by the width of the waste distribution on the surface of the base die-cut product 3 during the first single cycle of brush 2's use, representing the brush's capacity to adsorb waste under non-electrostatic conditions. After correction, the width of the brush refers to its capacity to adsorb waste electrostatically under electrostatic conditions.

[0082] Optionally, under the condition that the end of the basic die-cut product 3 that has not been brushed by the brush 2 cannot reach the edge of the brush 2 within the set sampling period, the optional range of the set sampling period is [1.8s, 2.2s].

[0083] Preferably, in this embodiment, under the condition that the end of the basic die-cut product 3 that has not been brushed by the brush 2 cannot reach the edge of the brush 2 within the set sampling period, the preferred embodiment of the set sampling period is 2.0s.

[0084] Those skilled in the art will understand that the preferred setting of 2.0s is a preferred embodiment under the condition that the end of the basic die-cut product 3 that has not been brushed by the brush 2 within the set sampling period cannot reach the edge of the brush 2. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the set sampling period according to the actual application scenario or implementation environment.

[0085] In implementation, the control mechanism determines a scattered fault based on the change in the waste distribution area exceeding a preset change in waste distribution area, and controls the horizontal moving element to reduce the horizontal distance between the brush 2 and the input roller group. This solves the problem that when the input roller group operates for a long time, the increased heat leads to an increase in the volume of the input active roller 14 and the input driven roller 15, resulting in a smaller distance between them. This increases the pressure on the base die-cut product 3, making it easier for waste adhering to the surface of the base die-cut product 3 to be adhered to the input driven roller 15. Furthermore, when the input driven roller 15 rotates, the waste adhering to it is more likely to accumulate. Waste material adhering to the upper end of the brush 2 is easily splashed onto the surface of the base die-cut product 3 due to vibration and other reasons, affecting the efficiency of the waste handling mechanism in cleaning up waste. By reducing the horizontal distance between the brush 2 and the input end roller group, the probability of waste material adhering to the input end driven roller 15 splashing onto the upper end of the brush 2 when the input end driven roller 15 rotates is reduced, thereby reducing the probability of waste material from the upper end of the brush 2 falling onto the surface of the base die-cut product 3 and improving the efficiency of the waste handling mechanism in cleaning up waste.

[0086] Specifically, the control mechanism is connected to the image sensor 4 and the vertical moving element, respectively. Under the condition that the absolute value of the difference between the width of the brush 2 and the width of the waste distribution on the surface of the basic die-cut product 3 is less than or equal to a preset difference, the vertical moving element determines that it is an adsorption type fault and reduces the vertical distance between the brush 2 and the basic die-cut product 3. Then, it samples the waste projection area several times at a preset sampling interval. Based on the fact that the change in the waste projection area at the preset sampling interval is greater than the preset change in the waste projection area, the vertical distance between the brush 2 and the basic die-cut product 3 is adjusted a second time to increase the vertical distance between the brush 2 and the basic die-cut product 3.

[0087] Optionally, when the cleaning mechanism is in the conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preset sampling interval can be selected in the range of [2.5s, 3.5s].

[0088] Preferably, in this embodiment, when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%, the preferred embodiment of the preset sampling interval is 3s.

[0089] Those skilled in the art will understand that the preferred setting of 3s is a preferred embodiment when the cleaning mechanism is under the conditions of temperature: 15℃~30℃ and humidity: 40%~60%. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the preset sampling interval according to the changes in the temperature and humidity conditions of the cleaning mechanism.

[0090] In practice, the control mechanism determines to increase the vertical distance between the brush 2 and the basic die-cut product 3 based on the fact that the change in the projected area of ​​the waste material under the preset sampling interval is greater than the preset change in the projected area of ​​the waste material. This solves the problem that when the brush 2 removes the waste material from the surface of the basic die-cut product 3, the waste material is easily lifted up, and the lifted waste material interferes with the image sensor 4 in acquiring the image, thereby improving the accuracy of the image sensor 4 in acquiring the image.

[0091] Optionally, the waste projection area is 16cm below the photosensitive surface of the image sensor 4, which is directly opposite the image sensor 4. 2 Given the area of ​​waste within a certain range, the selectable range for the change in the projected area of ​​the waste is [1.5cm]. 2 2.2cm 2 ].

[0092] Preferably, in this embodiment, the projected area of ​​the waste material is 16cm below the photosensitive surface of the image sensor 4. 2 Given the area of ​​waste within a certain range, the preferred embodiment for the change in the projected area of ​​the waste is 1.8 cm². 2 .

[0093] As will be understood by those skilled in the art, 1.8cm 2 The preferred configuration is that the waste projection area is 16cm below the photosensitive surface of the image sensor 4, which is directly opposite the image sensor 4. 2 This is a preferred embodiment under the condition of the area of ​​waste within the range. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the amount of change in the preset waste projection area according to the actual application scenario or implementation environment.

[0094] Specifically, the change in the waste projection area is the difference between the waste projection area obtained from the first sampling at the preset sampling interval and the waste projection area obtained from each subsequent sampling.

[0095] During implementation, when the cleaning mechanism is operating under conditions of temperature 15℃~30℃ and humidity 40%~60%, if the change in the projected area of ​​the waste exceeds the preset value for the change in the projected area of ​​the waste by less than 0.4cm... 2 When the vertical distance is within a certain range, the vertical moving element adjusts the vertical distance between the brush 2 and the base die-cut product 3 to 1.2 times the current vertical distance between the brush 2 and the base die-cut product 3; when the change in the waste projection area exceeds the preset value of the change in waste projection area by more than 0.4 cm... 2 At that time, for every 0.1cm exceeding 2 The vertical distance between the brush 2 and the basic die-cut product 3 is increased to 1.2 times the original distance; for example, in one possible embodiment, the change in the projected area of ​​the waste exceeds the preset change in the projected area of ​​the waste by 0.7 cm. 2 At this point, the vertical distance between the brush 2 and the basic die-cut product 3 increases to 1.2×1.2×1.2×1.2=2.0736 times the original distance.

[0096] Working principle of the vertical moving element: The first stepper motor 7 drives the lead screw 5 to rotate, and the lead screw nut 6 drives the brush 2 to move vertically along the guide rod 8. Depending on whether the first stepper motor 7 rotates forward or backward, the brush 2 can move vertically upward or downward.

[0097] The working principle of the horizontal moving element is as follows: the second stepper motor (not shown in the figure) drives the drive wheel to rotate, and the drive wheel drives the synchronous belt 11 to move. When the synchronous belt 11 moves, it drives the slider 12 fixed on it to move horizontally along the guide rail 13. Depending on whether the second stepper motor rotates forward or reverse, the slider 12 can move horizontally to the left or right.

[0098] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
