Description

Technical Field

[0001] The invention relates to the technical field of diaphragm punching devices, and in particular to a vehicle-mounted diaphragm automatic punching device and method. Background Art

[0002] In the manufacturing process of automotive interior parts, the forming and punching accuracy of vehicle-mounted diaphragms (such as diaphragms for control panels, button diaphragms, etc.) is crucial to the subsequent assembly quality. Existing vehicle-mounted diaphragm punching methods are mostly semi-automatic or manually assisted modes. Usually, the operator repeatedly positions and fine-tunes the diaphragm before completing the processing through the punching die. This leads to time consumption and human errors in positioning, and it is often difficult to meet the increasingly stringent processing accuracy and production efficiency requirements. In addition, the traditional vehicle-mounted diaphragm processing system lacks efficient automatic loading and unloading functions and accurate detection methods for the position of the diaphragm, resulting in long production cycles, low material utilization, and unstable processes. This not only increases production costs, but also restricts the quality consistency and speed of large-scale industrial production.

[0003] Therefore, how to develop a new type of vehicle-mounted diaphragm automatic punching device to overcome the above shortcomings has become a topic to be studied by those skilled in the art. Summary of the invention

[0007] As a further solution of the present invention: the CCD mechanism is used to control the feeding mechanism to calibrate the material loading punching table according to the image taken by the CCD camera, until the mark point coincides with the positioning reference point, and then control the punching mechanism to drive the punching head to perform the punching action; At least two mark points are provided, at least two CCD cameras are provided and are used to photograph different mark points respectively, and the CCD mechanism is preset with positioning reference points corresponding to the at least two mark points one by one; The feeding mechanism also includes a second transfer assembly, which is used to drive the material carrier punching and cutting table to move in a direction perpendicular to the transfer direction of the first transfer assembly. Specifically, the direction in which the first transfer assembly drives the material carrier punching and cutting table to move is the X direction, and the second transfer assembly is used to drive the material carrier punching and cutting table to move in the Y direction, and the Y direction is perpendicular to the X direction.

[0008] As a further solution of the present invention: the feeding mechanism also includes a feeding lifting mechanism for driving the feeding platform to lift and lower, and a lifting control component connected to the feeding lifting mechanism, the lifting control component is provided with a photoelectric switch for detecting whether the feeding platform reaches a preset initial height threshold, specifically, the photoelectric switch emits light blocked by the feeding platform that reaches the initial height threshold; The unloading mechanism also includes an unloading lifting mechanism for driving the unloading platform to lift up and down; The material loading and handling assembly includes a material loading and handling module and a material loading and handling adsorption member driven by the material loading and handling module and used for grabbing the material to be punched; The material unloading and conveying assembly comprises a material unloading and conveying module and a material unloading adsorption piece which is driven by the material unloading and conveying module and is used for grabbing the punched materials.

[0011] The present invention also provides another technical solution: a method for automatically punching a vehicle-mounted membrane, comprising the following steps: Preset step: set the mark point photographed by the CCD camera on the incoming material to obtain the material to be punched, and preset the positioning reference point in the area photographed by the CCD camera; preset the initial height threshold of the feeding table according to the maximum lifting stroke of the feeding adsorbent; preset the feeding distance of 1 unit of the feeding step; Loading step: placing a stack or a pile of materials to be punched, which is formed by stacking at least two materials to be punched, on a loading table; Initialization step: Use the photoelectric switch of the lifting control component to control the loading platform to stop after it reaches the initial height threshold to avoid rising beyond the predetermined lifting stroke. The first transfer component drives the loading punching and cutting platform to move to the initial position; Loading step: the loading and transporting assembly transports the material to be punched on the loading table and places it on the loading and punching table; Feeding step: the first transfer assembly drives the material loading punching table to enter the punching position; Correction punching and cutting steps: The CCD camera takes a picture of the mark point of the material to be punched on the material-carrying punching and cutting table, and determines whether the position of the mark point coincides with the positioning reference point. If not, the feeding mechanism controls the material-carrying punching and cutting table to move until the mark point coincides with the positioning reference point; if so, the punching and cutting mechanism controls the punching and cutting head to punch the material to be punched on the punching and cutting position; Feeding step: after executing the correction punching step, the first transfer assembly drives the material carrying punching table to move a feeding distance of 1 unit in a direction away from the initial position; Sub-cycle punching step: determine whether there is a mark point in the image taken by the CCD camera, if so, execute the correction punching step and the feeding step again; if not, execute the material return step; Material return step: the first transfer assembly drives the material loading and punching table to return to the initial position; Unloading step: the unloading and transporting assembly transports the punched materials on the loading and punching table and places them on the unloading table; Total cycle punching steps: cyclic execution of loading step ~ unloading step.

[0012] As a further solution of the present invention: the presetting step further includes: presetting a feeding number threshold value that matches the number of membrane sheets to be punched on the material to be punched; The feeding step and the correction punching step also include: Material determination step: determine whether there are mark points in the image taken by the CCD camera. If so, perform the calibration and punching step; The steps of correcting the punching are as follows: determining whether the position of the mark point coincides with the positioning reference point; if not, the feeding mechanism controls the material-carrying punching table to move until the mark point coincides with the positioning reference point; if so, the punching mechanism controls the punching head to punch the material to be punched at the punching position; The feeding step further includes: accumulating the number of feeding times and determining whether the current number of feeding times reaches a feeding number threshold, if not, executing a sub-cycle punching step, and if so, executing a material withdrawal step; The sub-cycle punching steps are: executing the material presence judgment step, the correction punching step and the feeding step again.

[0013] As a further solution of the present invention: the presetting step further includes: placing an empty material warning plate on the loading platform; The loading step is: placing a stack of materials to be punched formed by stacking at least two materials to be punched on an empty material warning board; The material loading steps are as follows: the material loading and handling component carries the material to be punched on the empty material warning plate and places it on the material loading and punching table; The material presence judgment step is as follows: judging whether there is a mark point in the image captured by the CCD camera, if so, executing the calibration punching step; if not, judging whether the material feeding step has been executed, if so, executing the empty material warning step (indicating that there is no material on the empty material warning board at this time, and what the material loading and transporting component transports to the material loading and punching table in the material loading step is the empty material warning board, not the material to be punched, so even if the material loading and punching table enters the punching position, the CCD camera cannot capture the mark point); Empty material warning step: an empty material warning message is issued to warn of empty material, and the execution of the total cycle punching step is stopped. The specific warning method can be that the display screen of the CCD mechanism displays an empty material warning or the buzzer emits an empty material warning sound or the empty material warning light is lit.

[0014] As a further solution of the present invention: the loading step also includes: when the loading and transporting assembly transports the material to be punched upward, the top edge of the material to be punched scratches the anti-adhesion strip, and because the material to be punched is a sheet structure, the edge of the material to be punched is bent to a certain extent, thereby preventing two or more sheets of the material to be punched from sticking together and affecting the subsequent punching action. Specifically, when two or more sheets of the material to be punched are stuck together, the edges of the material to be punched are bent to a certain extent due to the scraping of the anti-adhesion strip during the process of the stuck material to be punched being transported upward, thereby causing other stuck materials to be punched to fall off.

[0015] The present invention solves the following technical problems and obtains corresponding beneficial effects by arranging a punching mechanism, a feeding mechanism, a loading mechanism, a unloading mechanism and a punching control mechanism, wherein the punching control mechanism adopts a CCD mechanism: 1. Automatic feeding and precise positioning: The feeding mechanism in the device drives the material-carrying punching and cutting table to switch freely between the initial position and the punching and cutting position through the first transfer component, which can realize accurate feeding action. At the same time, the CCD mechanism is used to detect and identify the image of the material to be punched and cut, and can judge whether it has been aligned with the set positioning reference point according to the mark points on the surface of the material. Once the material position meets the requirements, the CCD mechanism will control the punching and cutting mechanism to perform the punching and cutting action, so that there is no need for repeated manual adjustments, and automatic and accurate positioning operations are realized, which greatly improves production efficiency and punching and cutting accuracy.

[0016] 2. Automatic loading and unloading improves efficiency and quality: The loading mechanism transfers the material to be punched from the loading platform to the loading punching platform, while the unloading mechanism transfers the punched material from the loading punching platform to the unloading platform. The entire process does not require manual intervention, which effectively reduces the burden on operators, reduces the displacement error caused by manual handling and the problem of unstable production rhythm, thereby ensuring a smooth production process and improving product consistency and quality stability.

[0017] 3. Improve material utilization and reduce costs: Through the precise positioning of the CCD mechanism and the repetitive high-precision feeding of the automatic feeding device, the present invention can reduce the misalignment and cutting of materials and the scrap rate, maximize the use of diaphragm materials, reduce material waste, and thus effectively reduce production costs.

[0018] In summary, the vehicle-mounted membrane automatic punching device described in this solution beneficially combines the punching mechanism, feeding mechanism, loading mechanism, unloading mechanism and CCD mechanism, and realizes a high-precision, high-efficiency, fully automatic membrane punching processing mode. Its significant beneficial effect is that it solves the technical problems of low manual operation efficiency, insufficient precision, material waste and lack of automation in traditional processes, and provides a feasible high-level technical solution for the large-scale and intelligent production of vehicle-mounted membranes.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present invention. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0031] The purpose of the present invention is to provide a vehicle-mounted membrane automatic punching device and method to address the deficiencies of the prior art, and specifically to provide a vehicle-mounted membrane automatic punching device that integrates automatic feeding, automatic loading and unloading, and precise positioning and punching. This device has highly automated and intelligent features. Through precise visual detection (CCD monitoring) and a controllable feeding mechanism, the material to be punched can be quickly and accurately transported and positioned to the punching position, thereby significantly reducing the uncertainty caused by human operation factors while improving processing accuracy and efficiency.

[0032] like Figure 1 to Figure 10 As shown, in an embodiment of the present invention, a vehicle-mounted film automatic punching device is provided, comprising: a punching mechanism 1, a feeding mechanism 2, a loading mechanism 3, a unloading mechanism 4 and a punching control mechanism. Among them: The punching mechanism 1 comprises a punching head 11 and a punching position 101 arranged at the bottom of the punching head 11 ; optionally, the punching mechanism 1 may include a hydraulic or pneumatic drive component to achieve stable downward pressing of the punching head 11 .

[0033] The feeding mechanism 2 includes a loading and punching table 21 and a first conveying component 22 for driving the loading and punching table 21 in and out of the punching position 101; optionally, the first conveying component 22 of the feeding mechanism 2 can be a guide rail structure driven by a linear slide, a ball screw or a servo motor to ensure that the material table can smoothly and accurately enter and exit the punching area.

[0034] The loading mechanism 3 includes a loading platform 31 and a loading and transporting assembly 32 for transporting the material a to be punched on the loading platform 31 to the material loading and punching platform 21; optionally, the loading and transporting assembly 32 can be equipped with a vacuum suction cup or a mechanical clamp to prevent the material from slipping and shifting.

[0035] The unloading mechanism 4 includes an unloading table 41 and a unloading and transporting assembly 42 for transporting the punched material b on the loading and punching table 21 to the unloading table 41; optionally, the unloading and transporting assembly 42 can also be equipped with a suitable vacuum suction cup or mechanical clamp for automatically picking up and placing processed products or waste materials.

[0036] The punching control mechanism is connected to the punching mechanism 1 and is used to control the punching mechanism 1 to drive the punching head 11 to perform a punching action when the material a to be punched on the material-carrying punching platform 21 is located at the punching position 101. Optionally, the punching control mechanism can realize data communication with a sensor, a PLC control unit or an industrial computer, so that the system automatically triggers the punching action according to the material in place signal.

[0037] Through the above structure, each mechanism cooperates with each other to realize the fully automated processing of the membrane from loading, feeding, punching to unloading. This solution effectively avoids the inefficiency and positioning errors caused by multiple manual alignment and handling, making the production process more efficient and stable, and improving the consistency of finished product quality and processing accuracy.

[0038] In one embodiment, the punching control mechanism is a CCD mechanism 5, which includes a CCD camera 51 that shoots toward the punching position 101. The CCD mechanism 5 is used to determine whether the material is located at the punching position 101 according to the image captured by the CCD camera 51. If so, the punching mechanism 1 is controlled to drive the punching head 11 to perform a punching action. Optionally, the CCD camera 51 is an industrial-grade high-speed camera that can achieve high resolution and fast imaging.

[0039] The feeding mechanism 2 is preset with an initial position 201, and the first transfer assembly 22 is used to drive the material-carrying punching and cutting platform 21 to switch and move between the initial position 201 and the punching and cutting position 101; the loading and transporting assembly 32 is used to transport the material a to be punched on the loading and transporting platform 31 to the material-carrying punching and cutting platform 21 located at the initial position 201; the unloading and transporting assembly 42 is used to transport the punched and cut material b on the material-carrying punching and cutting platform 21 located at the initial position 201 to the unloading platform 41; The material a to be punched is provided with a mark point a21 photographed by a CCD camera 51, and the CCD mechanism 5 is used to control the movement of the feeding mechanism 2 until the mark point a21 coincides with the preset positioning reference point 53, and then the punching mechanism 1 is controlled to punch the material a to be punched. Optionally, the CCD mechanism 5 has a built-in image processing unit, and the relative position of the mark point a21 and the positioning reference point 53 is determined in real time by digital image recognition technology. The positioning reference point 53 can be set by software and stored in the control system to ensure 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, after completing the punching of a membrane, it can quickly return to the initial position 201 to carry out the unloading and loading of the next piece of material. Furthermore, through the detection of the position of the mark point a21 by the CCD camera 51, the material is accurately positioned and automatically calibrated / corrected, and the punching accuracy is effectively improved. CCD visual guidance significantly reduces the processing position error without manual intervention, thereby improving the automation degree and finished product yield of the production line.

[0040] In another embodiment, the CCD mechanism 5 is used to control the feeding mechanism 2 to calibrate the carrier punching table 21 according to the image captured by the CCD camera 51, until the mark point a21 coincides with the positioning reference point 53, and then the punching mechanism 1 is controlled to drive the punching head 11 to perform the punching action; at least two mark points a21 are provided, and at least two CCD cameras 51 are provided and respectively used to capture different mark points a21, and the CCD mechanism 5 is preset with positioning reference points 53 corresponding to at least two mark points a21; the feeding mechanism 2 also includes a second transfer component (not shown in the figure), and the second transfer component is used to drive the carrier punching table 21 to move in a direction perpendicular to the transfer direction of the first transfer component 22. Specifically, the direction in which the first transfer component 22 drives the carrier punching table 21 to move is the X direction, and the second transfer component is used to drive the carrier punching table 21 to move in the Y direction, and the Y direction is perpendicular to the X direction. Multiple CCD cameras 51 can be distributed at different positions above the punching position 101 to capture multi-point reference information. Multiple mark points a21 are conducive to comprehensive correction of errors in the X, Y directions and even in small angles. The second transfer component can be a lateral moving mechanism, such as a belt conveyor or a linear motor, to achieve precise calibration of the Y direction based on positioning in the X direction. Through two-dimensional movement control (X, Y directions), the device can cope with multi-dimensional errors of the material and further improve processing accuracy. Furthermore, the introduction of multiple mark points a21 and calibration movements in both directions (X, Y) enables the equipment to not only accurately adjust the front and rear positions of the material at the punching position 101, but also to make precise corrections in the left and right directions, thereby achieving more accurate multi-dimensional positioning. This greatly improves the processing accuracy of complex-shaped diaphragms, improves the consistency of finished products and reduces scrap rates.

[0041] In another embodiment, the feeding mechanism 3 further includes a feeding lifting mechanism 33 for driving the feeding platform 31 to rise and fall, and a lifting control component 34 connected to the feeding lifting mechanism 33. The lifting control component 34 is provided with a photoelectric switch for detecting whether the feeding platform 31 has reached a preset initial height threshold. Specifically, the photoelectric switch emits light blocked by the feeding platform 31 that has reached the initial height threshold. Optionally, the feeding lifting mechanism 33 can be a screw lift or a cylinder lift device, which is precisely positioned according to a set signal. The photoelectric switch accurately determines whether the feeding platform 31 has reached the preset initial height, ensuring that the feeding process starts from the same starting state, which is conducive to subsequent adsorption and handling.

[0042] The unloading mechanism 4 also includes an unloading lifting mechanism 43 for driving the unloading platform 41 to rise and fall; optionally, the unloading lifting mechanism 43 is similar to or the same as the loading lifting mechanism 33 to better adapt to different size or height requirements.

[0043] The loading and handling assembly 32 includes a loading and handling module 321 and a loading adsorption piece 322 driven by the loading and handling module 321 and used to grab the material a to be punched; the unloading and handling assembly 42 includes a unloading and handling module 421 and a unloading adsorption piece 422 driven by the unloading and handling module 421 and used to grab the punched material b. Specifically, the loading and handling module 321 / unloading and handling module 421 can adopt a parallel robot or a linear module, and be equipped with a negative pressure adsorption piece to ensure stable grasping of the diaphragm. Furthermore, by precisely controlling the height of the loading platform 31 and the unloading platform 41, it is possible to accurately remove materials from a pile of materials a to be punched in automated production and to orderly stack or classify the punched finished products. The height confirmation is carried out by the photoelectric switch, which reduces the errors of manual measurement and adjustment, thereby further improving the automation and stability of the production line.

[0044] In yet another embodiment, Figure 8 As shown, the material a to be punched includes at least one film a1 to be punched and a positioning edge material a2, and the mark point a21 is set on the positioning edge material a2; Fig. 9 As shown, the punched material b includes at least one punched film sheet b1 punched out by the punching head 11, and the scraps b2 formed by the positioning edge material a2 after punching; specifically, the edge material in the material a to be punched is provided with a mark point a21, which is convenient for CCD identification and positioning, and the scraps b2 formed after punching can be separated from the finished product.

[0045] The feeding suction piece 322 is provided with at least two feeding negative pressure suction nozzles 3221, at least one feeding negative pressure suction nozzle 3221 is used to suck the film a1 to be punched, and the other feeding negative pressure suction nozzle 3221 is used to suck the positioning edge material a2; specifically, during feeding, multi-nozzle zoned suction is used, so that the film and the positioning edge material a2 can be grabbed synchronously to avoid misalignment of the two.

[0046] The material unloading suction part 422 is provided with at least two material unloading negative pressure suction nozzles 4221, at least one material unloading negative pressure suction nozzle 4221 is used to absorb the punched film b1, and the other material unloading negative pressure suction nozzle 4221 is used to absorb the scraps b2. Specifically, when unloading, the finished products and waste materials are also classified, grabbed and sorted by multiple suction nozzles, which is helpful to automate the quality inspection or reuse process at the back end. Furthermore, through the clear division of labor of the multiple suction nozzles, the synchronous transportation of the film a1 to be punched and the positioning reference component is realized, and the sorting of the finished products and waste materials is realized when unloading. This can simplify the subsequent sorting process, reduce the risk of mixing, and improve the overall automation and efficiency of the production line.

[0047] In another embodiment, if Figure 4 As shown, the vehicle-mounted film automatic punching device also includes: an empty material warning plate 311 and an anti-adhesion component 312. Among them: The empty material warning plate 311 is placed on the loading platform 31 and can be sucked by the loading negative pressure suction nozzle 3221 to place the material a to be punched; specifically, the empty material warning plate 311 is a flat plate with a certain rigidity. When the material is exhausted, it can be directly sucked up by the loading mechanism 3, triggering an empty material warning, making it convenient for the operator to add material in time.

[0048] The anti-adhesion member 312 includes an anti-adhesion strip 312a disposed on one side of the loading platform 31 and extending into the top of the loading platform 31. Specifically, the anti-adhesion member 312 adopts a strip structure with elastic or anti-adhesion coating, and slightly bends the edge of the material by slightly moving it, thereby reducing the adhesion of two or more membranes due to static electricity or surface adsorption; further, the empty material warning board 311 can be used to give a timely warning in the absence of material, prevent the equipment from idling, and improve production continuity and management level; and the anti-adhesion strip 312a ensures that only one piece of material is taken each time the material is loaded, reducing errors and waste rates, and making the automation process smoother and more reliable.

[0049] The material loading and punching table 21 is equipped with a negative pressure adsorption component (not shown). After the loading and transporting component 32 places the material a to be punched on the loading table 31 onto the material loading and punching table 21, the negative pressure adsorption component fixes the material a to be punched by negative pressure adsorption. In this way, the material a to be punched is more stable at the punching position 101, avoiding the material from slipping during the subsequent positioning correction and punching process, thereby improving the punching accuracy and the qualified rate of finished products. At the same time, the application of the negative pressure adsorption component can reduce the complexity of the mechanical gripping device when clamping the material and the possible damage to the material surface, providing favorable conditions for realizing automated, high-precision and high-efficiency punching operations.

[0050] In another embodiment, a method for automatically punching a vehicle-mounted film comprises the following steps: Presetting step: setting the mark point a21 photographed by the CCD camera 51 on the incoming material to obtain the material a to be punched, and presetting the positioning reference point in the area photographed by the CCD camera 51; presetting the initial height threshold of the feeding table 31 according to the maximum lifting stroke of the feeding adsorbent 322; and presetting the feeding distance of 1 unit of the feeding step; Loading step: placing a stack or a pile of at least two materials a to be punched on the loading platform 31; Initialization step: using the photoelectric switch of the lifting control component 34 to control the loading platform 31 to stop after it reaches the initial height threshold, so as to avoid the lifting exceeding the predetermined lifting stroke, the first transfer component 22 drives the loading punching platform 21 to move to the initial position 201; Loading step: the loading and transporting assembly 32 transports the material a to be punched on the loading platform 31 and places it on the material loading and punching platform 21, and the negative pressure adsorption assembly sucks the material a to be punched; Feeding step: the first transfer assembly 22 drives the material carrying punching table 21 to enter the punching position 101; Correction punching step: CCD camera 51 photographs the mark point a21 of the material a to be punched on the material carrier punching platform 21, and determines whether the position of the mark point a21 coincides with the positioning reference point 53. If not, the feeding mechanism 2 controls the material carrier punching platform 21 to move until the mark point a21 coincides with the positioning reference point 53; if so, the punching mechanism 1 controls the punching head 11 to punch the material a to be punched on the punching position 101; Feeding step: After executing the calibration punching step, the first transfer assembly 22 drives the material carrying punching table 21 to move a unit of feeding distance in a direction away from the initial position 201; Sub-cycle punching step: determine whether there is a mark point a21 in the image captured by the CCD camera 51, if so, execute the correction punching step and the feeding step again; if not, execute the material return step; Material return step: the first transfer assembly 22 drives the material carrying punching and cutting platform 21 to return to the initial position 201; Unloading step: the unloading and transporting assembly 42 transports the punched material b on the material loading and punching platform 21 and places it on the unloading platform 41; Total cycle punching steps: cyclic execution of loading step ~ unloading step.

[0051] Specifically, in the preset step, the production process can quickly adapt to diaphragms of different batches and sizes through parameter settings (such as feed distance, initial height threshold). The correction punching step adopts a closed-loop visual 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 mark point a21 image information, forming an efficient closed-loop production mode. Furthermore, this method significantly reduces manual intervention through the orderly series connection of a series of automated steps. The combination of CCD positioning, automatic feeding and cycle mode makes the production process more continuous, efficient and precise, which not only reduces labor costs and labor intensity, but also can steadily improve the production line capacity and finished product quality.

[0052] In another embodiment, a method for automatically punching a vehicle-mounted film comprises the following steps: Presetting steps: setting the mark point a21 photographed by the CCD camera 51 for the incoming material to obtain the material a to be punched, and presetting the positioning reference point in the area photographed by the CCD camera 51; presetting the initial height threshold of the loading platform 31 according to the maximum lifting stroke of the loading adsorbent 322; presetting the feeding distance of 1 unit of the feeding step; presetting the feeding number threshold that matches the number of the film sheets a1 to be punched on the material a to be punched; placing the empty material warning plate 311 on the loading platform 31; Loading step: placing a stack of materials a to be punched, which is formed by stacking at least two materials a to be punched, on the empty material warning plate 311; Initialization step: using the photoelectric switch of the lifting control component 34 to control the loading platform 31 to stop after it reaches the initial height threshold, so as to avoid the lifting exceeding the predetermined lifting stroke, the first transfer component 22 drives the loading punching platform 21 to move to the initial position 201; Loading step: the loading and transporting component 32 transports the material a to be punched on the empty material warning plate 311 and places it on the material loading and punching table 21, and the negative pressure adsorption component sucks the material a to be punched; Feeding step: the first transfer assembly 22 drives the material carrying punching table 21 to enter the punching position 101; Material presence judgment step: judging whether there is a mark point a21 in the image captured by the CCD camera 51, if so, executing the calibration punching step; if not, judging whether the material feeding step has been executed, if so, executing the empty material warning step (indicating that there is no material on the empty material warning plate 311 at this time, and what is conveyed to the material carrier punching table 21 by the material loading and conveying assembly 32 in the material loading and conveying step is the empty material warning plate 311, not the material a to be punched, so even if the material carrier punching table 21 enters the punching position 101, the CCD camera 51 cannot capture the mark point a21); Correction punching step: determine 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 so, the punching mechanism 1 controls the punching head 11 to punch the material a to be punched on the punching position 101. Feeding step: after executing the correction punching step, the first transfer assembly 22 drives the material carrying punching table 21 to move a unit of feeding distance in a direction away from the initial position 201; the number of feeding times is accumulated, and it is determined whether the current number of feeding times reaches the feeding number threshold, if not, the sub-cycle punching step is executed, if so, the material return step is executed; Sub-cycle punching step: execute the material presence judgment step, correction punching step and feeding step again; Material return step: the first transfer assembly 22 drives the material carrying punching and cutting platform 21 to return to the initial position 201; Unloading step: the unloading and transporting assembly 42 transports the punched material b on the material loading and punching platform 21 and places it on the unloading platform 41; Total cycle punching steps: cyclic execution of loading step ~ unloading step; Empty material warning step: Send out empty material warning information to warn of empty material, and stop executing the total cycle punching step. The specific warning method can be that the display screen 52 of the CCD mechanism 5 displays an empty material warning or the buzzer emits an empty chat warning sound or the empty material warning light is lit. Specifically, the feed number threshold is pre-calculated to match the number of holes or shapes to be punched on the diaphragm. The material judgment step ensures that the next round of precise positioning and punching is performed only when there are still areas to be punched on the diaphragm, thereby improving resource utilization. When the feed number threshold is reached, the material is automatically returned, which can effectively control the production rhythm and reduce useless actions. The empty material warning board 311 can be detected by the CCD as no mark point a21 when there is no material a to be punched. When the feeding has been executed but there is still no mark point a21, it means that there is no material. The empty material warning can be prompted by sound, light or screen display. Furthermore, the production process is made more intelligent by managing the feed number threshold related to the actual number of diaphragms that can be punched. This method ensures that all punching tasks of each diaphragm are completed without waste, reducing unnecessary time and actions, thereby improving automation efficiency and economic benefits. By adding an empty material warning plate 311 in the feeding area and using visual detection, the equipment can automatically identify and issue an alarm when the material is exhausted, avoiding idling and ineffective production actions, and improving equipment utilization and work safety. This reminder mechanism makes production management more efficient and maintenance more timely.

[0053] Another embodiment, such as Figure 4As shown, the loading step also includes: during the upward process of the material a to be punched by the loading and transporting assembly 32, the top edge of the material a to be punched passes through the anti-adhesion strip 312a. Since the material a to be punched is a sheet structure, the edge of the material a to be punched is bent to a certain extent, thereby preventing two or more sheets of the material a to be punched from sticking together and affecting the subsequent punching action. Specifically, when two or more sheets of the material a to be punched are stuck together, during the upward process of the stuck material a to be punched, the edge of the material a to be punched is bent to a certain extent due to the scraping of the anti-adhesion strip 312a, thereby causing other materials a to be punched that are stuck at the bottom to fall off. The anti-adhesion strip 312a can be made of a wear-resistant material that is not easy to adhere to the material, such as Teflon or a special coated metal. The strip is set at an appropriate position and height so that the material is slightly but sufficiently deformed when it rises and passes through, and the lower layer of sticking material is removed. Furthermore, by slightly intervening on the edge of the material, potential adhered laminates can be effectively separated, reducing positioning errors, punching failures, or equipment jams caused by taking out multiple films at the same time. This measure can further ensure the reliability of a single loading action, improve the smoothness of the production process, and improve the product qualification rate.
