[0057] 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 a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present utility model. The connection relationships shown in the drawings are only for clear description and do not limit the connection method.

[0058] The purpose of this invention is to provide an automatic vehicle-mounted film punching device and method to address the shortcomings of existing technologies. Specifically, it aims to provide an automated vehicle-mounted film punching device that integrates automatic feeding, automatic loading and unloading, precise positioning, and punching. This device features a high degree of automation and intelligence. Through precise visual detection (CCD monitoring) and a controllable feeding mechanism 2, the material to be punched, a, can be quickly and accurately transported and positioned at the punching position 101, thereby significantly reducing the uncertainty caused by human operation while improving processing accuracy and efficiency.

[0059] like Figures 1-10 As shown in the figure, an automatic punching and cutting device for vehicle-mounted films is provided in this embodiment of the utility model, including: a punching and cutting mechanism 1, a feeding mechanism 2, a loading mechanism 3, a unloading mechanism 4, and a punching and cutting control mechanism. Wherein:

[0060] The punching mechanism 1 has a punching head 11 and a punching position 101 located at the bottom of the punching head 11; optionally, the punching mechanism 1 may include a hydraulic or pneumatic drive assembly to achieve stable downward pressure of the punching head 11.

[0061] The feeding mechanism 2 comprises a material carrying die-cutting table 21 and a first moving assembly 22 for driving the material carrying die-cutting table 21 to move in and out of the die-cutting position 101. Optionally, the first moving assembly 22 of the feeding mechanism 2 can be a linear sliding table, a ball screw or a guide rail structure driven by a servo motor, to ensure that the material table moves in and out of the die-cutting area smoothly and accurately.

[0062] The feeding mechanism 2 comprises a material carrying die-cutting table 21 and a first moving assembly 22 for driving the material carrying die-cutting table 21 to move in and out of the die-cutting position 101. Optionally, the first moving assembly 22 of the feeding mechanism 2 can be a linear sliding table, a ball screw or a guide rail structure driven by a servo motor, to ensure that the material table moves in and out of the die-cutting area smoothly and accurately.

[0063] The feeding mechanism 2 comprises a material carrying die-cutting table 21 and a first moving assembly 22 for driving the material carrying die-cutting table 21 to move in and out of the die-cutting position 101. Optionally, the first moving assembly 22 of the feeding mechanism 2 can be a linear sliding table, a ball screw or a guide rail structure driven by a servo motor, to ensure that the material table moves in and out of the die-cutting area smoothly and accurately.

[0064] The feeding mechanism 2 comprises a material carrying die-cutting table 21 and a first moving assembly 22 for driving the material carrying die-cutting table 21 to move in and out of the die-cutting position 101. Optionally, the first moving assembly 22 of the feeding mechanism 2 can be a linear sliding table, a ball screw or a guide rail structure driven by a servo motor, to ensure that the material table moves in and out of the die-cutting area smoothly and accurately.

[0065] Through the above structure, each mechanism cooperates with each other to realize the full automation of the film from feeding, feeding, die cutting to discharging. This scheme effectively avoids the low efficiency and positioning error caused by manual multiple positioning and handling, makes the production process more efficient and stable, and improves the consistency of product quality and processing precision.

[0066] In one embodiment, the die-cutting control mechanism is a CCD mechanism 5, which comprises a CCD camera 51 facing the die-cutting position 101. The CCD mechanism 5 is used to determine whether the material is located in the die-cutting position 101 according to the image captured by the CCD camera 51, and if so, controls the die-cutting mechanism 1 to drive the die-cutting head 11 to perform the die-cutting action. Optionally, the CCD camera 51 is an industrial high-speed camera that can realize high-resolution and fast imaging.

[0067] The feeding mechanism 2 is pre-set with an initial position 201, and the first moving assembly 22 is used to drive the material carrying die-cutting table 21 to move between the initial position 201 and the die-cutting position 101. The feeding mechanism 2 is pre-set with an initial position 201, and the first moving assembly 22 is used to drive the material carrying die-cutting table 21 to move between the initial position 201 and the die-cutting position 101. The feeding mechanism 2 is pre-set with an initial position 201, and the first moving assembly 22 is used to drive the material carrying die-cutting table 21 to move between the initial position 201 and the die-cutting position 101.

[0068] The to-be-punched material a is provided with a mark point a21 photographed by the CCD camera 51, the CCD mechanism 5 is used to control the feeding mechanism 2 to move until the mark point a21 coincides with the preset positioning reference point 53, and then the punching mechanism 1 is controlled to punch the to-be-punched material a. Optionally, the CCD mechanism 5 is provided with an image processing unit, and the relative position between the mark point a21 and the positioning reference point 53 is determined in real time through digital image recognition technology. The positioning reference point 53 can be set by software and stored in the control system, so that different batches of materials can be quickly called and set. Through the reciprocating movement between the initial position 201 and the punching position 101, the device can quickly return to the initial position 201 after completing the punching of one film piece, so as to carry out the feeding and the feeding of the next material. Further, through the detection of the position of the mark point a21 by the CCD camera 51, the accurate positioning and automatic calibration / correction of the material are realized, and the punching precision is effectively improved. The CCD visual guidance significantly reduces the processing position error, and does not need manual intervention, thereby improving the automation degree of the production line and the yield of finished products.

[0069] In another embodiment, the CCD mechanism 5 is used to control the feeding mechanism 2 to calibrate the material loading punching table 21 according to the image photographed by the CCD camera 51, and when the mark point a21 coincides with the positioning reference point 53, the punching mechanism 1 is controlled to drive the punching head 11 to perform the punching action; the mark point a21 is provided with at least two mark points, the CCD camera 51 is provided with at least two CCD cameras and is used to photograph different mark points a21 respectively, and the CCD mechanism 5 is provided with the positioning reference point 53 corresponding to the at least two mark points a21; the feeding mechanism 2 further comprises a second moving assembly (not shown in the figure), and the second moving assembly is used to drive the material loading punching table 21 to move in a direction perpendicular to the moving direction of the first moving assembly 22. Specifically, the direction in which the first moving assembly 22 drives the material loading punching table 21 to move is defined as the X direction, and the second moving assembly is used to drive the material loading punching table 21 to move in the Y direction, and the Y direction is perpendicular to the X direction. The plurality of CCD cameras 51 can be distributed at different positions above the punching position 101 to capture multiple reference information. The plurality of mark points a21 are beneficial to the comprehensive correction of the X, Y direction and even the small angle error. The second moving assembly can be a transverse moving mechanism, such as a belt conveyor or a linear motor, to realize the accurate calibration in the Y direction based on the X direction positioning. Through the two-dimensional moving control (X, Y direction), the device can cope with the multi-dimensional error of the material, and further improve the machining precision. Further, the introduction of the plurality of mark points a21 and the calibration movement in the two directions (X, Y) enables the device to not only accurately adjust the front and back positions of the material in the punching position 101, but also accurately correct the left and right directions, so as to realize the multi-dimensional positioning with higher precision. This greatly improves the machining precision of the film piece with complex shape, improves the consistency of finished products and reduces the waste rate.

[0070] In yet another embodiment, the feeding mechanism 3 further comprises a feeding lifting mechanism 33 for driving the lifting of the feeding table 31, and a lifting control assembly 34 connected with the feeding lifting mechanism 33, the lifting control assembly 34 being provided with a photoelectric switch for detecting whether the feeding table 31 reaches a preset initial height threshold, specifically, the photoelectric switch emits light rays blocked by the feeding table 31 reaching the initial height threshold; optionally, the feeding lifting mechanism 33 can be a screw lifting machine or a cylinder lifting device, which is precisely positioned according to the set signal. The photoelectric switch accurately judges that the feeding table 31 reaches the preset initial height, ensuring that the feeding process starts from the same initial state, which is beneficial to subsequent adsorption and carrying.

[0071] The discharging mechanism 4 further comprises a discharging lifting mechanism 43 for driving the lifting of the discharging table 41; optionally, the discharging lifting mechanism 43 is similar or identical to the feeding lifting mechanism 33, so as to better adapt to different size or height requirements.

[0072] The feeding carrying assembly 32 comprises a feeding carrying module 321 and a feeding suction accessory 322 driven by the feeding carrying module 321 and used for grabbing the to-be-punched material a; the discharging carrying assembly 42 comprises a discharging carrying module 421 and a discharging suction accessory 422 driven by the discharging carrying module 421 and used for grabbing the punched material b. Specifically, the feeding carrying module 321 / discharging carrying module 421 can adopt a parallel robot or a linear module, and is matched with a negative pressure suction accessory, so as to ensure stable grabbing of the film. Furthermore, through accurate control of the height of the feeding table 31 and the discharging table 41, accurate taking out of the material from a stack of to-be-punched materials a and orderly stacking or classified placing of the punched finished products are realized in the automatic production. The height is confirmed by the photoelectric switch, which reduces the measurement and adjustment errors of manual operation, thereby further improving the automation and stability of the production line.

[0073] In still another embodiment, as shown in Figure 8 , the to-be-punched material a comprises at least one to-be-punched film a1 and a positioning edge material a2, and a mark a21 is arranged on the positioning edge material a2; as shown in Figure 9 , the punched material b comprises at least one punched film b1 punched out by the punching head 11 and corner waste b2 formed by the positioning edge material a2 after being punched; specifically, the edge material in the to-be-punched material a is provided with the mark a21, which facilitates the recognition and positioning of the CCD, and the corner waste b2 formed after punching can be separated from the finished product.

[0074] The feeding suction accessory 322 is provided with at least two feeding negative pressure suction nozzles 3221, at least one feeding negative pressure suction nozzle 3221 being used for adsorbing the to-be-punched film a1, and the other feeding negative pressure suction nozzle 3221 being used for adsorbing the positioning edge material a2; specifically, during feeding, the film and the positioning edge material a2 can be synchronously grabbed through multi-suction-nozzle partition adsorption, so as to avoid mispositioning of the two.

[0075] The blanking suction accessory 422 is provided with at least two blanking negative pressure suction nozzles 4221, at least one of which is used to suck the cut film piece b1, and the other is used to suck the corner waste b2. Specifically, the finished product and waste are classified, grabbed and sorted by multiple suction nozzles during blanking, which helps the quality detection or recycling process of the automatic backend. Further, through the clear suction mode of multiple suction nozzles, the synchronous carrying of the to-be-cut film piece a1 and the positioning reference component is realized, and the sorting of the finished product and the waste is realized during blanking. This can simplify the subsequent sorting process, reduce the risk of mixing materials, and improve the overall automation and efficiency of the production line.

[0076] In another embodiment, as shown in FIG. 11, the vehicle-mounted film automatic cutting device further comprises a blank pre-warning plate 311 and an anti-adhesion member 312. Wherein: Figure 4

[0077] The blank pre-warning plate 311 is placed on the feeding table 31 and can be sucked by the feeding negative pressure suction nozzle 3221 to place the to-be-cut material a. Specifically, the blank pre-warning plate 311 is a flat plate with a certain rigidity, which can be directly sucked by the feeding mechanism 3 when the material is exhausted, triggering the blank warning, so that the operator can add the material in time.

[0078] The anti-adhesion member 312 includes an anti-adhesion bar 312a arranged on one side of the feeding table 31 and extending into the top of the feeding table 31. Specifically, the anti-adhesion member 312 adopts a bar structure with elastic or anti-adhesion coating, which slightly bends the edge of the material by slightly pushing, thereby reducing the adhesion of two or more film pieces due to static electricity or surface adsorption. Further, the blank pre-warning plate 311 can timely alarm in the no-material state, preventing the equipment from idling, and improving the production continuity and management level. The anti-adhesion bar 312a ensures that only one piece of material is taken each time, reducing the error and waste rate, making the automatic process more smooth and reliable.

[0079] The material carrying cutting table 21 is provided with a negative pressure suction assembly (not shown in the figure). When the feeding carrying assembly 32 places the to-be-cut material a on the feeding table 31 on the material carrying cutting table 21, the negative pressure suction assembly is used to fix the to-be-cut material a by negative pressure suction. In this way, the to-be-cut material a is more stable at the cutting position 101, avoiding slipping of the material during subsequent positioning correction and cutting process, thereby improving the cutting precision and product qualification rate. At the same time, the application of the negative pressure suction assembly can reduce the complexity of the mechanical grabbing device during material clamping and the damage to the surface of the material, providing favorable conditions for realizing automatic, high-precision and high-efficiency cutting operation.

[0080] In another embodiment, a vehicle-mounted film automatic cutting method comprises the following steps:

[0081] ​Presetting step: taking the mark point a21 of the incoming material by the CCD camera 51 to obtain the material to be punched a, and presetting the positioning reference point in the area shot by the CCD camera 51; presetting the initial height threshold of the feeding table 31 according to the maximum lifting stroke of the feeding suction accessory 322; presetting the feeding distance of 1 unit of the feeding step;

[0082] Loading step: placing the stack or a stack of the material to be punched a formed by stacking at least 2 pieces of the material to be punched a on the feeding table 31;

[0083] Initialization step: using the photoelectric switch of the lifting control assembly 34 to control the feeding table 31 to stop after lifting to the initial height threshold, avoiding lifting beyond the predetermined lifting stroke, and driving the first transfer assembly 22 to move the material carrying punching table 21 to the initial position 201;

[0084] Feeding step: the feeding handling assembly 32 carries the material to be punched a on the feeding table 31 and places it on the material carrying punching table 21, and the negative pressure suction assembly sucks the material to be punched a;

[0085] Feeding step: the first transfer assembly 22 drives the material carrying punching table 21 to enter the punching position 101;

[0086] Correcting and punching step: the CCD camera 51 shoots the mark point a21 of the material to be punched a on the material carrying punching table 21, judges whether the position of the mark point a21 coincides with the positioning reference point 53, if not, the feeding mechanism 2 controls the material carrying punching table 21 to move until the mark point a21 coincides with the positioning reference point 53; if yes, the punching mechanism 1 controls the punching head 11 to punch the material to be punched a on the punching position 101;

[0087] Feeding step: after executing the correcting and punching step, the first transfer assembly 22 drives the material carrying punching table 21 to move 1 unit of feeding distance away from the initial position 201;

[0088] Sub-cycle punching step: judging whether there is a mark point a21 in the image shot by the CCD camera 51, if yes, executing the correcting and punching step and the feeding step again; if not, executing the material returning step;

[0089] Material returning step: the first transfer assembly 22 drives the material carrying punching table 21 to return to the initial position 201;

[0090] Unloading step: the unloading handling assembly 42 carries the punched material b on the material carrying punching table 21 and places it on the unloading table 41;

[0091] Total cycle punching step: cyclically executing the feeding step-unloading step.

[0092] Specifically, in the preset steps, parameter settings (such as feed distance and initial height threshold) allow the production process to quickly adapt to different batch sizes and specifications of films. The calibration and punching step employs a closed-loop vision control strategy to achieve precise alignment and high-precision punching. The sub-cycle step intelligently determines whether to continue punching based on the presence or absence of marker point a21 in the image information, forming an efficient closed-loop production mode. Furthermore, this method significantly reduces manual intervention through the orderly chaining of a series of automated steps. The combination of CCD positioning, automatic feeding, and the cyclic mode makes the production process more continuous, efficient, and precise, not only reducing labor costs and labor intensity but also steadily improving production line capacity and finished product quality.

[0093] In another embodiment, an automatic punching method for vehicle-mounted films includes the following steps:

[0094] Preset steps: Set the marker point a21 captured by the CCD camera 51 to obtain the material to be punched a, and preset the positioning reference point in the area captured by the CCD camera 51; preset the initial height threshold of the loading platform 31 according to the maximum lifting stroke of the loading adsorption component 322; preset the feeding distance of 1 unit of the feeding step; preset the feeding number threshold matching the number of punched films a1 on the material to be punched a; place the empty material warning plate 311 on the loading platform 31;

[0095] Loading steps: Place the stack of at least two pieces of material to be punched a on the empty material warning plate 311;

[0096] Initialization steps: Using the photoelectric switch of the lifting control component 34, the loading table 31 is controlled to rise and fall to the initial height threshold and then stop to avoid rising beyond the predetermined lifting stroke. The first transfer component 22 drives the loading punching table 21 to move to the initial position 201.

[0097] Feeding steps: The feeding and handling component 32 picks up the material to be punched a on the empty material warning plate 311 and places it on the material-carrying punching table 21, and the negative pressure adsorption component sucks up the material to be punched a.

[0098] Feeding steps: The first transfer component 22 drives the material-carrying punching table 21 into the punching position 101;

[0099] Material availability determination step: Determine whether there is a mark point a21 in the image captured by CCD camera 51. If yes, execute the correction punching step; if no, determine whether the feeding step has been executed. If yes, execute the empty material alarm step (indicating that there is no material on the empty material warning plate 311 at this time, and that the material handling component 32 in the feeding step moved the empty material warning plate 311 to the material-carrying punching table 21, not the material to be punched a. Therefore, even if the material-carrying punching table 21 enters the punching position 101, CCD camera 51 will not capture the mark point a21).

[0100] Correcting punching step: judging whether the position of mark point a21 coincides with the positioning reference point 53, if not, the feeding mechanism 2 controls the carrier punching table 21 to move until the mark point a21 coincides with the positioning reference point 53; if yes, the punching mechanism 1 controls the punching head 11 to punch the material a on the punching position 101;

[0101] Feeding step: after executing the correcting punching step, the first transfer assembly 22 drives the carrier punching table 21 to move 1 unit of feeding distance away from the initial position 201; accumulating the feeding number, and judging whether the current feeding number reaches the feeding number threshold, if not, executing the sub-cycle punching step, if yes, executing the material returning step;

[0102] Sub-cycle punching step: executing the material judging step, the correcting punching step and the feeding step again;

[0103] Material returning step: the first transfer assembly 22 drives the carrier punching table 21 to return to the initial position 201;

[0104] Discharging step: the discharging and carrying assembly 42 carries the punched material b on the carrier punching table 21 and places it on the discharging table 41;

[0105] Total cycle punching step: cyclically executing the feeding step~the discharging step;

[0106] Empty material warning step: issuing an empty material warning information to warn the empty material, and stopping executing the total cycle punching step, the specific warning method can use the display screen 52 of the CCD mechanism 5 to display the empty material warning or use the buzzer to issue the empty material warning sound or use the empty material warning light to light. Specifically, the feeding number threshold is matched with the number of holes or shapes to be punched on the film by pre-calculation. The material judging step ensures that the next round of accurate positioning and punching is only executed when there is still an area to be punched on the film, improving resource utilization. When the feeding number threshold is reached, the material is returned automatically, which can effectively control the production rhythm and reduce unnecessary actions. The empty material warning plate 311 can be detected by the CCD as no mark point a21 when there is no material to be punched a, which indicates that there is no material. The empty material warning can be prompted by sound, light or screen display. Further, through the feeding number threshold related to the actual punchable number of the film, the production process is more intelligent. This method ensures that all punching tasks of each film are completed without waste, reduces unnecessary time consumption and actions, thereby improving the automation efficiency and economic benefits. By adding the empty material warning plate 311 in the feeding area and using visual detection, when the material is exhausted, the equipment can automatically identify and issue a warning, avoiding idling and invalid production actions, improving equipment utilization and work safety. This prompting mechanism makes production management more efficient and maintenance more timely.

[0107] Another embodiment, asFigure 4 As shown, the feeding step further includes that the feeding and conveying assembly 32 conveys the to-be-cut material a upward, and the top edge of the to-be-cut material a passes through the anti-adhesion prong 312a, and due to the sheet structure of the to-be-cut material a, the edge of the to-be-cut material a is bent to a certain extent, thereby preventing two or more to-be-cut materials a from being adhered together and affecting the subsequent cutting. Specifically, when two or more to-be-cut materials a are adhered together, the adhered to-be-cut material a is conveyed upward, and due to the scraping of the anti-adhesion prong 312a, the edge of the to-be-cut material a is bent to a certain extent, thereby causing the other to-be-cut material a adhered at the bottom to fall off. The anti-adhesion prong 312a can be made of a material that is resistant to wear and not easy to adhere to the material, such as Teflon or a special coated metal. The prong is set at a proper position and height, so that the material passing upward is slightly deformed but enough to push the lower adhered material away. Further, through the slight intervention of the edge of the material, the potential adhered and stacked materials are effectively separated, reducing the positioning error, cutting failure or equipment jam caused by multiple films being taken out at the same time. This measure can further ensure the reliability of a single feeding action and improve the smoothness of the production process and the product qualification rate.
