Description

TECHNICAL FIELD

[0001] The utility model relates to a loading device technical field especially relates to a kind of vehicle-mounted diaphragm anti-adhesion loading mechanism and vehicle-mounted diaphragm automatic punching device. BACKGROUND

[0002] In the mass processing of vehicle-mounted diaphragm and other sheet materials, the loading link is particularly critical. The traditional loading method often uses simple lifting machinery to assist in taking out the diaphragm one by one, but due to static electricity or surface adhesion between sheet materials, they are often adhered to each other, which can easily cause multiple sheets to be taken out at one time, resulting in inaccurate positioning or punching failure. Especially on the automatic production line, if there is no effective anti-adhesion measure, improper loading can seriously affect the overall production efficiency and quality. SUMMARY

[0003] The utility model aims at the deficiency of prior art to provide a kind of vehicle-mounted diaphragm anti-adhesion loading mechanism and vehicle-mounted diaphragm automatic punching device, to solve the following technical problems:

[0004] 1. How to prevent multiple diaphragms from being taken out at one time when there is static electricity or surface adhesion between sheet materials, causing position or quantity recognition error. 2. How to effectively move or separate the topmost diaphragm from the lower material during the loading process, reducing manual intervention and improving the degree of automation of the production line. 3. How to achieve stable, efficient and sustainable loading process through a simple structure that can adapt to diaphragms of different thicknesses or sizes.

[0005] The utility model realizes the above-mentioned purpose through the following technical scheme: a kind of vehicle-mounted diaphragm anti-adhesion loading mechanism, comprising: loading table, for placing to be punched material;Anti-adhesion piece, including the anti-adhesion prong arranged in one side of loading table, one end of anti-adhesion prong is inserted into the top of loading table, and is located above to be punched material placed in loading table;And discharging and carrying assembly, for carrying to be punched material on loading table away. Specifically, by arranging anti-adhesion prong on one side of loading table, the edge or top surface of the material can be slightly moved or bent when it is lifted, preventing multiple diaphragms from being adhered and lifted at the same time, thereby improving the loading accuracy. Anti-adhesion prong is simple in structure, small in space occupation, easy to install or retrofit, and conducive to reducing the production line modification cost. Avoiding manual sorting of adhered diaphragms multiple times, reducing the workload of operators, and improving the degree of automation.

[0006] 2. As a further scheme of the present utility model: the anti-adhesion piece further comprises a telescopic mechanism installed on the feeding table, the telescopic mechanism comprises a connecting seat and a telescopic rod installed on the connecting seat, and the other end of the anti-adhesion piece is installed on one end of the telescopic rod away from the connecting seat. Specifically, through the telescopic or angle adjustment function of the telescopic rod, the position and insertion depth of the anti-adhesion piece can be flexibly adjusted to adapt to vehicle-mounted films or stacked heights of different thicknesses and sizes. The telescopic mechanism can quickly adjust the position or force when the feeding demand changes, improving the versatility and adaptability of the equipment. When not in use or needing maintenance, the piece can be easily retracted or disassembled, facilitating maintenance and later maintenance.

[0007] 3. As a further scheme of the present utility model: the anti-adhesion piece is installed with a rotatable poking wheel. Specifically, when the topmost to-be-punched material is lifted, one side of the top surface of the to-be-punched material is resisted by the rotation of the poking wheel. The design of the poking wheel can not only poke the lifted to-be-punched material to bend slightly to peel off two or more pieces of to-be-punched material adhered together, but also prevent the to-be-punched material from being adhered and lifted. At the same time, the rotatable design of the poking wheel can also reduce the friction force to prevent the surface of the to-be-punched material from being scratched. Through the design of the rotatable poking wheel, rolling is used instead of sliding to effectively reduce the friction between the material and the piece and reduce the scratching of the film surface. The poking wheel can more flexibly "peel off" the adhered material when poking, further reducing the problem of multiple adhesion and improving the anti-adhesion effect. The structure of the poking wheel is simple and easy to implement, and the maintenance or replacement cost is low, meeting the requirements of different film surface protection.

[0008] 4. As a further scheme of the present utility model: at least two poking wheels are provided, and at least one poking wheel is installed at the end of the end of the anti-adhesion piece inserted into the top of the feeding table. Specifically, the multi-poking wheel structure can form multi-point poking in the material feeding area, which can more effectively ensure the anti-adhesion effect of the same side or multiple sides. At least one poking wheel is installed at the end to generate poking at the most critical edge or corner, enhancing the reliability of the separation of the sheet. The multiple poking wheels disperse the load and work cooperatively to improve the overall durability and service life, while also avoiding excessive wear of a single poking wheel.

[0009] 5. As a further scheme of the present application, the anti-adhesion poking strip is a straight poking strip or an arc bending poking strip, and has elasticity. Specifically, the straight poking strip is convenient for linearly poking the edges of the materials, and has simple structure and low manufacturing cost; the arc bending poking strip can cooperate with the curved surface of the edges of the film sheet, and generate a more actual shape poking angle, reduce the stress concentration on the edges of the film sheet, and have higher adaptability. The user can flexibly select the straight poking strip or the arc bending poking strip according to different film sheet sizes or production requirements, and realize more optimal anti-adhesion effect. The anti-adhesion poking strip has certain elastic deformation force. The anti-adhesion poking strip can be made of a material (such as an elastic metal strip or a high polymer elastic material) having certain elastic deformation force. When the topmost film sheet is sucked up by the feeding and carrying assembly, the poking strip will slightly contact the edges or top surface of the film sheet and elastically deform slightly. Since the poking strip itself has elastic deformation capability, when the edges of the film sheet contact the poking strip, the buffer can be provided in a short distance, so as to avoid excessive collision or scratching of the film sheet. At the same time, the mechanical stress impact on the poking strip or the film sheet is also reduced, and the service life of the device is prolonged.

[0010] 6. As a further scheme of the present application, the connecting seat is threadedly connected to one end of the telescopic rod, and the anti-adhesion poking strip is threadedly connected to the other end of the telescopic rod. Specifically, the angle, slope and height of the anti-adhesion poking strip can be adjusted through the loose screw, and the height can be further adjusted through the telescopic rod, so as to have higher applicability. The design of thread connection and loose adjustment can greatly improve the adjustment flexibility of the poking strip, and the poking strip can be accurately set according to different film sheet sizes and stacking thicknesses. During installation or maintenance, the poking strip can be quickly disassembled or the position of the poking strip can be changed through simple screw loosening operation, so as to improve the equipment maintenance efficiency. The poking strip can be finely adjusted according to the position or environmental changes of the feeding table, so as to ensure that the poking strip always maintains the optimal anti-adhesion angle and force during work.

[0011] 7. As a further scheme of the present application, a vehicle-mounted film sheet automatic punching device comprises:

[0012] a punching mechanism having a punching head and a punching position arranged at the bottom of the punching head;

[0013] a feeding mechanism comprising a material carrying punching table and a first moving assembly for driving the material carrying punching table to enter and exit the punching position;

[0014] a feeding mechanism, which is the vehicle-mounted film sheet anti-adhesion feeding mechanism according to any one of the preceding aspects, comprises a feeding and carrying assembly for carrying the material to be punched on the feeding table to the material carrying punching table;

[0015] a discharging mechanism comprising a discharging table and a discharging and carrying assembly for carrying the punched material on the material carrying punching table to the discharging table; and

[0016] The punching control mechanism is connected with the punching mechanism, and is used for controlling the punching mechanism to drive the punching head to perform a punching action when the material to be punched on the material loading and punching table is located at the punching position.

[0017] 8. As a further scheme of the present application, the punching control mechanism is a CCD mechanism, and the CCD mechanism comprises a CCD camera for shooting the punching position, and is used for judging whether the material is located at the punching position according to the image shot by the CCD camera.

[0018] The feeding mechanism is provided with an initial position, the first transferring assembly is used for driving the material loading and punching table to move between the initial position and the punching position, the material loading and carrying assembly is used for carrying the material to be punched on the material loading table to the material loading and punching table located at the initial position, and the material unloading and carrying assembly is used for carrying the punched material on the material loading and punching table located at the initial position to the material unloading table.

[0019] The material to be punched is provided with a mark point shot by the CCD camera, the CCD mechanism is used for controlling the feeding mechanism to move until the mark point coincides with a preset positioning reference point, and then the punching mechanism is controlled to punch the material to be punched.

[0020] 9. As a further scheme of the present application, the material loading mechanism further comprises a material loading lifting mechanism used for driving the material loading table to lift, and a lifting control assembly connected with the material loading lifting mechanism, and the lifting control assembly is provided with a photoelectric switch used for detecting whether the material loading table reaches a preset initial height threshold.

[0021] The material unloading mechanism further comprises a material unloading lifting mechanism used for driving the material unloading table to lift.

[0022] The material loading and carrying assembly comprises a material loading and carrying module and a material loading suction accessory driven by the material loading and carrying module and used for grabbing the material to be punched.

[0023] The material unloading and carrying assembly comprises a material unloading and carrying module and a material unloading suction accessory driven by the material unloading and carrying module and used for grabbing the punched material.

[0024] The present application has the following beneficial effects:

[0025] 1. Preventing continuous sheet feeding: When the blank carrying assembly lifts the topmost film sheet, the anti-sticking prongs can exert a slight poking or slight bending on the edge or top surface of the film sheet, causing the other film sheets stuck together to peel off, avoiding the continuous sheets from being sucked up at the same time.

[0026] 2. Improved automation: By adding anti-sticking components in the feeding link, the manual intervention or repeated operations caused by sheet sticking are greatly reduced, making the feeding process more coherent and efficient, and improving the automation level of the entire production line.

[0027] 3. Simple structure and easy maintenance: The anti-sticking prongs occupy a small space and are easy to install, and can be adjusted in position or angle according to the thickness or size of the material, improving applicability and reducing equipment maintenance costs.

[0028] In summary, the scheme can effectively avoid the situation of multiple sheets being sucked up at the same time due to static electricity or surface adhesion of the vehicle-mounted film sheet, ensuring the feeding quality and subsequent punching precision, and has significant practical value and application prospect.

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. It can be understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for clear description, and does not limit the connection mode.

[0042] The present application aims to provide a vehicle-mounted film automatic punching device to overcome the shortcomings of the prior art, specifically aims to provide a vehicle-mounted film automatic punching device integrating automatic feeding, automatic feeding and discharging, and precise positioning and punching. The device has high automation and intelligence, and through precise visual detection (CCD monitoring) and controllable feeding mechanism, the material to be punched can be quickly and accurately conveyed and positioned to the punching position, thereby improving the processing precision and efficiency while significantly reducing the uncertainty caused by human operation.

[0043] As shown in Figures 1-10 In the embodiments of the present application, a vehicle-mounted film automatic punching device is provided, which comprises a punching mechanism 1, a feeding mechanism 2, a feeding mechanism 3, a discharging mechanism 4 and a punching control mechanism. Wherein:

[0044] The punching mechanism 1 has a punching head 11 and a punching position 101 arranged at the bottom of the punching head 11. Optionally, the punching mechanism 1 can include a hydraulic or pneumatic driving assembly to realize stable pressing of the punching head 11.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 is convenient for CCD recognition and positioning, and the corner waste b2 formed after punching can be separated from the finished product.

[0058] 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.

[0059] The feeding suction unit 422 is equipped with at least two feeding negative pressure suction nozzles 4221. At least one feeding negative pressure suction nozzle 4221 is used to absorb the punched film b1, and the other feeding negative pressure suction nozzle 4221 is used to absorb the edge waste b2. Specifically, during feeding, the finished product and waste are also classified, grasped, and sorted by multiple suction nozzles, which helps to automate the quality inspection or reuse process in the back end. Furthermore, through the clearly defined suction method of multiple suction nozzles, the film a1 to be punched and the positioning reference component are transported synchronously, and the finished product and waste are sorted during feeding. This simplifies the subsequent sorting process, reduces the risk of mixing materials, and improves the overall automation and efficiency of the production line.

[0060] In another embodiment, such as Figure 4 As shown, the vehicle-mounted automatic film punching device also includes: an empty material warning plate 311 and an anti-sticking connector 312. Wherein:

[0061] The empty material warning plate 311 is placed on the feeding platform 31 and can be held by the feeding negative pressure suction nozzle 3221. It is used to place the material to be punched a. Specifically, the empty material warning plate 311 is a plate with a certain rigidity. When the material is exhausted, it can be directly sucked up by the feeding mechanism 3 to trigger the empty material warning, so that the operator can add material in time.

[0062] The anti-sticking component 312 includes an anti-sticking lever 312a disposed on one side of the loading platform 31 and extending into the top of the loading platform 31. Specifically, the anti-sticking component 312 adopts a lever structure with elasticity or anti-stick coating. By slightly flicking, the edge of the material is slightly bent, thereby reducing the adhesion of two or more films due to static electricity or surface adsorption. Furthermore, the empty material warning plate 311 can provide timely warning when there is no material, preventing the equipment from running idle and improving production continuity and management level. The anti-sticking lever 312a ensures that only one piece of material is picked up each time, reducing errors and scrap rate, making the automated process smoother and more reliable.

[0063] The material-carrying punching table 21 is equipped with a negative pressure adsorption component (not shown in the figure). After the feeding and conveying component 32 places the material to be punched a from the feeding table 31 onto the material-carrying punching table 21, the negative pressure adsorption component uses negative pressure to adsorb and fix the material to be punched a. In this way, the material to be punched a is more stable at the punching position 101, avoiding slippage of the material during subsequent positioning correction and punching, thereby improving punching accuracy and finished product qualification rate. At the same time, the application of the negative pressure adsorption component can reduce the complexity of the mechanical gripping device during material handling and the potential damage to the material surface, providing favorable conditions for achieving automated, high-precision, and high-efficiency punching operations.

[0064] In another embodiment, an automatic punching method for vehicle-mounted films includes the following steps:

[0065] 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;

[0066] 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;

[0067] 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;

[0068] 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;

[0069] Feeding step: the first transfer assembly 22 drives the material carrying punching table 21 to enter the punching position 101;

[0070] 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;

[0071] 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 the feeding distance away from the initial position 201;

[0072] 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;

[0073] Material returning step: the first transfer assembly 22 drives the material carrying punching table 21 to return to the initial position 201;

[0074] 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;

[0075] Total cycle punching step: cyclically executing the feeding step-unloading step.

[0076] 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.

[0077] In another embodiment, an automatic punching method for vehicle-mounted films includes the following steps:

[0078] 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;

[0079] Loading steps: Place the stack of at least two pieces of material to be punched a on the empty material warning plate 311;

[0080] 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.

[0081] 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.

[0082] Feeding steps: The first transfer component 22 drives the material-carrying punching table 21 into the punching position 101;

[0083] 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).

[0084] 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;

[0085] 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;

[0086] Sub-cycle punching step: executing the material judging step, the correcting punching step and the feeding step again;

[0087] Material returning step: the first transfer assembly 22 drives the carrier punching table 21 to return to the initial position 201;

[0088] Material discharging step: the material discharging and carrying assembly 42 carries the punched material b on the carrier punching table 21 and places it on the material discharging table 41;

[0089] Total cycle punching step: cyclically executing the material feeding step~material discharging step;

[0090] 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 automatically returned, 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 material 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.

[0091] Another embodiment, asFigure 4 As shown, the feeding step further includes: in the process of feeding and carrying the to-be-cut material a by the feeding and carrying assembly 32, the top edge of the to-be-cut material a is scraped by 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, in the process of being carried and raised, 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 is slightly deformed when it rises, and the lower adhered material is pushed away. Further, through the slight intervention of the edge of the material, the potential adhered and stacked sheets are effectively separated, reducing the positioning error, cutting failure or equipment jam caused by multiple sheets 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.

[0092] A vehicle-mounted film production method for producing a vehicle-mounted film by using the vehicle-mounted film automatic cutting device according to any one of the preceding embodiments, the method comprising the steps of the vehicle-mounted film automatic cutting method according to any one of the preceding embodiments.

[0093] As shown in Figure 4 , Figure 11 and Figure 12 , a vehicle-mounted film anti-adhesion feeding mechanism is provided in the embodiments of the present application, comprising: a feeding table 31, an anti-adhesion piece 312, and a discharging and carrying assembly 42. Wherein:

[0094] The feeding table 31 is used for placing the to-be-cut material a;

[0095] The anti-adhesion piece 312 includes an anti-adhesion prong 312a arranged on one side of the feeding table 31, one end of the anti-adhesion prong 312a extending into the top of the feeding table 31 and being located above the to-be-cut material a placed on the feeding table 31;

[0096] The discharging and carrying assembly 42 is used for carrying away the to-be-cut material a on the feeding table 31. Specifically, by arranging the anti-adhesion prong 312a on one side of the feeding table 31, the edge or top surface of the material can be slightly poked or bent when it is carried up, preventing multiple sheets from being adhered and taken out at the same time, thereby improving the feeding accuracy. The anti-adhesion prong 312a has a simple structure and occupies a small space, facilitating quick installation or later modification, which is conducive to reducing the production line modification cost. Manual multiple sorting of adhered sheets is avoided, the workload of the operator is reduced, and the degree of automation is improved.

[0097] Further scheme: the anti-adhesion member 312 further comprises a telescopic mechanism 313 mounted on the feeding table 31, the telescopic mechanism 313 comprising a connecting seat 313a and a telescopic rod 313b mounted on the connecting seat 313a, and the other end of the anti-adhesion stick 312a is mounted on the end of the telescopic rod 313b away from the connecting seat 313a. Specifically, through the telescopic or angle adjustment function of the telescopic rod 313b, the position and insertion depth of the anti-adhesion stick 312a can be flexibly adjusted to adapt to vehicle-mounted films of different thicknesses, sizes or stacking heights. The telescopic mechanism 313 can quickly make position or force fine adjustment when the feeding demand changes, improving the versatility and adaptability of the equipment. When not in use or requiring maintenance, the stick can be easily retracted or removed for easy maintenance and later maintenance.

[0098] Further scheme: the anti-adhesion stick 312a is provided with a rotatable poking wheel 312b. Specifically, when the topmost to-be-cut material a is lifted, the poking wheel 312b is rotatably arranged on one side of the top surface of the to-be-cut material a. The design of the poking wheel 312b can not only poke the lifted to-be-cut material a to bend slightly to peel off two or more pieces of to-be-cut material a adhered together to prevent the to-be-cut material a from being adhered and lifted, but also can reduce the friction force to prevent the surface of the to-be-cut material a from being scratched. Through the design of the rotatable poking wheel 312b, rolling is used instead of sliding to effectively reduce the friction between the material and the stick and reduce the scratching of the film surface. The poking wheel 312b can more flexibly “peel off” the adhered material when poking, further reducing the problem of multiple pieces of adhesion and improving the anti-adhesion effect. The structure of the poking wheel 312b is simple and easy to implement, and the maintenance or replacement cost is low, meeting the requirements for protecting different film surfaces.

[0099] Further scheme: the poking wheel 312b is provided with at least two, and at least one poking wheel 312b is mounted on the end of the end of the anti-adhesion stick 312a extending into the top of the feeding table 31. Specifically, the multi-poking wheel 312b structure can form multi-point poking in the material feeding area, which can more effectively ensure the anti-adhesion effect of the same side or multiple sides. At least one poking wheel 312b is mounted on the end, so that it produces poking at the most critical edge or corner, enhancing the reliability of the separation of the sheet. The multi-poking wheel 312b disperses the load and works cooperatively to improve the overall durability and service life, while also avoiding excessive wear of a single poking wheel 312b.

[0100] Further scheme: the anti-adhesion pushing strip 312a is a straight pushing strip or an arc bending pushing strip, and has elasticity. Specifically, the straight pushing strip is convenient for linear pushing of the material edge, and has simple structure and low manufacturing cost; the arc bending pushing strip can cooperate with the curved surface of the film edge to generate a pushing angle more in line with the actual shape, reduce stress concentration on the film edge, and have higher adaptability. The user can flexibly select the straight pushing strip or the arc bending pushing strip according to different film sizes or production needs, to achieve a better anti-adhesion effect. The anti-adhesion pushing strip 312a has a certain elastic deformation force. The anti-adhesion pushing strip 312a can be made of a material with a certain elastic deformation force, such as an elastic metal strip or a high polymer elastic material. When the topmost film is sucked up by the feeding and carrying assembly 32, the pushing strip will slightly contact the film edge or top surface and elastically deform slightly. Since the pushing strip itself has elastic deformation capability, when the film edge contacts the pushing strip, it can provide a buffer within a short distance, avoiding excessive collision or scratching of the film. At the same time, it also reduces the mechanical stress impact on the pushing strip or the film, prolonging the service life of the device.

[0101] Further scheme: the connecting seat 313a is threadedly connected to one end of the telescopic rod 313b, and the anti-adhesion pushing strip 312a is threadedly connected to the other end of the telescopic rod 313b. Specifically, the angle, slope and height of the anti-adhesion pushing strip 312a can be adjusted by a loose screw, and the height can be further adjusted by the telescopic rod 313b, having higher applicability. The design of thread connection and loose adjustment greatly improves the adjustment flexibility of the pushing strip, and the pushing strip can be accurately set according to different film sizes and stacking thicknesses. During installation or maintenance, the pushing strip can be quickly disassembled or the position of the pushing strip can be changed by simply loosening the screw, improving the equipment maintenance efficiency. The pushing strip can be fine-tuned according to the position or environmental changes of the feeding table 31, to ensure that the pushing strip always maintains the best anti-adhesion angle and force during work.

[0102] Another scheme: a vehicle-mounted film automatic punching device, comprising:

[0103] a punching mechanism 1 having a punching head 11 and a punching position 101 provided at the bottom of the punching head 11;

[0104] a feeding mechanism 2 comprising a material carrying punching table 21 and a first moving assembly 22 for driving the material carrying punching table 21 to move in and out of the punching position 101;

[0105] a feeding mechanism 3, which is any one of the vehicle-mounted film anti-adhesion feeding mechanisms described above, wherein the feeding and carrying assembly 32 is used to carry the material to be punched a on the feeding table 31 to the material carrying punching table 21;

[0106] a discharging mechanism 4 comprising a discharging table 41 and a discharging carrying assembly 42 for carrying the punched material b on the material carrying punching table 21 to the discharging table 41; and

[0107] The punching control mechanism is connected with the punching mechanism 1, and is used for controlling the punching mechanism 1 to drive the punching head 11 to perform the punching action when the material to be punched a on the material loading and punching table 21 is located at the punching position 101. Specifically, the anti-adhesion material loading mechanism 3 is integrated with the automatic punching system to realize the intelligent integrated operation process from material loading to punching, and to reduce manual operation. The anti-adhesion material loading mechanism 3 provides stable and "single sheet" output of the film supply, improves the punching positioning accuracy, and reduces the risk of equipment jamming and repeated punching. The fully automatic design significantly improves the production efficiency of the whole production line, and greatly reduces the scrap rate and downtime caused by adhesion.

[0108] Further scheme: the punching control mechanism is a CCD mechanism 5, the CCD mechanism 5 includes a CCD camera 51 facing the punching position 101, and the CCD mechanism 5 is used for judging whether the material is located at the punching position 101 according to the image shot by the CCD camera 51.

[0109] The feeding mechanism 2 is provided with an initial position 201, the first transfer assembly 22 is used for driving the material loading and punching table 21 to switch and move between the initial position 201 and the punching position 101; the material loading and carrying assembly 32 is used for carrying the material to be punched a on the material loading table 31 to the material loading and punching table 21 located at the initial position 201; and the material unloading and carrying assembly 42 is used for carrying the punched material b on the material loading and punching table 21 located at the initial position 201 to the material unloading table 41.

[0110] The material to be punched a is provided with a mark point a21 shot by the CCD camera 51, the CCD mechanism 5 is used for controlling the feeding mechanism 2 to move until the mark point a21 coincides with a preset positioning reference point 53, and then controlling the punching mechanism 1 to punch the material to be punched a. Specifically, the CCD visual positioning is combined with the adhesion prevention and control to effectively ensure that the film carried to the material loading and punching table 21 each time is in a precise and identifiable single sheet state, and to reduce the positioning error.
