Description

[0001] The utility model relates to a diaphragm material moving device technical field especially a variable pitch unloading adsorption subassembly, variable pitch material moving subassembly and punching device. BACKGROUND

[0002] In the punching production process of the vehicle-mounted diaphragm, the material after punching (that is, the punched material) often needs to be unloaded. Since the punched diaphragm is usually composed of finished diaphragm (that is, the punched diaphragm) and corner waste, the traditional unloading method often needs to be transported in steps: first, the finished diaphragm is transported, and then the corner waste is handled separately. This not only increases the complexity of the operation process, but also reduces the production efficiency. When changing different size specifications of diaphragm, the arrangement position of the finished product and the waste on the material punching table changes accordingly. If the distance between the multiple suction nozzles of the adsorption device is fixed, it is difficult to adapt to the one-time unloading demand of multi-specification products. In addition, using a simple mechanical method is more likely to cause mixing, wrong taking and operation errors, which is not conducive to the stable operation of the automatic production line. Therefore, an adsorption assembly with flexibility and adjustability is needed to realize one-time synchronous adsorption and transportation of finished diaphragm and corner waste of different sizes and distribution positions.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor 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 the purpose of clear description, and does not limit the connection mode.

[0058] The present application aims at providing a vehicle-mounted film automatic punching device to overcome the shortcomings of the prior art, specifically aims at providing a vehicle-mounted film automatic punching device integrating automatic feeding, automatic feeding and discharging, and accurate positioning and punching. The device has high automation and intelligence, and through accurate visual detection (CCD monitoring) and controllable feeding mechanism, the to-be-punched material 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.

[0059] AsFigures 1 to 10 As shown in the embodiment of the present application, a film automatic punching device for vehicle is provided, comprising a punching mechanism 1, a feeding mechanism 2, a feeding mechanism 3, a discharging mechanism 4 and a punching control mechanism. Wherein:

[0060] 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.

[0061] The feeding mechanism 2 includes 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; 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 enters and exits the punching area smoothly and accurately.

[0062] The feeding mechanism 3 includes a feeding table 31 and a feeding carrying assembly 32 for carrying the material to be punched a on the feeding table 31 to the material carrying punching table 21; optionally, the feeding carrying assembly 32 can be equipped with a vacuum suction cup or a mechanical clamp to prevent the material from slipping and position deviation.

[0063] The discharging mechanism 4 includes 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; optionally, the discharging carrying assembly 42 can also be equipped with a suitable vacuum suction cup or mechanical clamp jaw for automatic picking and placing of the finished product or waste material.

[0064] 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 punching action when the material to be punched a on the material carrying punching table 21 is located in 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 positioning signal.

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

[0066] In one embodiment, the punching control mechanism is a CCD mechanism 5, the CCD mechanism 5 includes a CCD camera 51 facing the punching position 101, the CCD mechanism 5 is used for judging whether the material is located in the punching position 101 according to the image shot by the CCD camera 51, and if so, controlling the punching mechanism 1 to drive the punching head 11 to perform punching action. Optionally, the CCD camera 51 is an industrial high-speed camera, which can realize high resolution and fast imaging.

[0067] The feeding mechanism 2 is provided with an initial position 201, the first transfer 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 carrying assembly 32 is used to carry the material to be cut a on the feeding table 31 to the material carrying die-cutting table 21 at the initial position 201; and the discharging carrying assembly 42 is used to carry the cut material b on the material carrying die-cutting table 21 at the initial position 201 to the discharging table 41.

[0068] The material to be cut a is provided with a mark point a21 photographed by the CCD camera 51, 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 control the die-cutting mechanism 1 to cut the material to be cut a. Optionally, the CCD mechanism 5 is provided with an image processing unit, which determines the relative position of the mark point a21 and the positioning reference point 53 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 die-cutting position 101, after the die-cutting of one film is completed, the initial position 201 can be quickly returned to carry out the discharging and feeding of the next piece of material. Further, 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, which effectively improves the die-cutting precision. The CCD visual guidance significantly reduces the machining position error, without the need for manual intervention, thereby improving the automation degree of the production line and the yield of finished products.

[0069] In another embodiment, the CCD mechanism 5 is configured to control the feeding mechanism 2 to align the material loading and 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 control the punching mechanism 1 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 configured to capture different mark points a21, and the CCD mechanism 5 is provided with positioning reference points 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), which is configured to drive the material loading and punching table 21 to move in a direction perpendicular to the moving direction of the first moving assembly 22. Specifically, the first moving assembly 22 drives the material loading and punching table 21 to move in the X direction, and the second moving assembly is configured to drive the material loading and punching table 21 to move in the Y direction, and the Y direction is perpendicular to the X direction. A plurality of CCD cameras 51 can be distributed at different positions above the punching position 101 to capture multi-point reference information. The plurality of mark points a21 are beneficial to the comprehensive correction of X, Y direction and even small angle errors. 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 errors of the material, and further improve the processing precision. Furthermore, the introduction of multiple 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, thereby realizing multi-dimensional positioning with higher precision. This greatly improves the processing precision of the complex-shaped diaphragm, improves the consistency of the finished product and reduces the waste rate.

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

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

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

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

[0074] The feeding suction accessory 322 is provided with at least two feeding negative pressure suction nozzles 3221, at least one feeding negative pressure suction nozzle 3221 is used for adsorbing the to-be-cut film a1, and the other feeding negative pressure suction nozzle 3221 is 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-nozzle partition adsorption, so that misplacement of the film and the positioning edge material a2 is avoided.

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

[0076] In another embodiment, as shown in Figure 4 , the vehicle-mounted film automatic cutting device further comprises an empty material warning plate 311 and an anti-adhesion piece 312. Wherein:

[0077] The empty material early warning plate 311 is placed on the feeding table 31 and can be adsorbed by the upper feeding negative pressure suction nozzle 3221, and is used for placing the material to be punched a; specifically, the empty material early warning plate 311 is a certain rigid flat plate, which can be directly sucked by the feeding mechanism 3 when the material is exhausted, to trigger the empty material warning, so as to facilitate the operator to add the material in time.

[0078] The anti-adhesion member 312 includes an anti-adhesion bar 312a arranged on one side of the feeding table 31 and extending into the top of the feeding table 31. Specifically, the anti-adhesion member 312 adopts a bar structure with an elastic or anti-adhesion coating, which slightly bends the edge of the material by slightly pushing, so as to reduce the adhesion of two or more film pieces due to static electricity or surface adsorption; further, the empty material early warning plate 311 can timely alarm in the empty state, to prevent the equipment from idling, and to improve the production continuity and management level; and the anti-adhesion bar 312a ensures that only one piece of material is taken each time, reduces the error and waste piece rate, and makes the automatic process more smooth and reliable.

[0079] The material carrying punching table 21 is provided with a negative pressure adsorption assembly (not shown in the figure). When the feeding and carrying assembly 32 places the material to be punched a on the feeding table 31 on the material carrying punching table 21, the negative pressure adsorption assembly is used 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, and the material is prevented from slipping during subsequent positioning correction and punching process, so as to improve the punching precision and the qualified rate of finished products. At the same time, the application of the negative pressure adsorption assembly can reduce the complexity of the mechanical grabbing device when the material is grabbed and the damage to the surface of the material, which provides favorable conditions for realizing automatic, high-precision and high-efficiency punching operation.

[0080] In another embodiment, a vehicle-mounted film piece automatic punching method includes the following steps:

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

[0082] The loading step: the stack or a stack of at least two pieces of material to be punched a is placed on the feeding table 31;

[0083] The initialization step: the photoelectric switch of the lifting control assembly 34 is used to control the feeding table 31 to stop after lifting to the initial height threshold, so as to avoid lifting beyond the predetermined lifting stroke, and the first transfer assembly 22 drives the material carrying punching table 21 to move to the initial position 201;

[0084] The feeding carrying assembly 32 carries the to-be-cut material a on the feeding table 31 and places it on the material carrying cutting table 21, and the negative pressure adsorption assembly adsorbs the to-be-cut material a;

[0085] The feeding step: the first moving assembly 22 drives the material carrying cutting table 21 to enter the cutting position 101;

[0086] The correction cutting step: the CCD camera 51 photographs the mark point a21 of the to-be-cut material a on the material carrying cutting 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 movement of the material carrying cutting table 21 until the mark point a21 coincides with the positioning reference point 53; if yes, the cutting mechanism 1 controls the cutting head 11 to cut the to-be-cut material a on the cutting position 101;

[0087] The feeding step: after the correction cutting step is performed, the first moving assembly 22 drives the material carrying cutting table 21 to move in the direction away from the initial position 201 by a feeding distance of one unit;

[0088] The sub-cycle cutting step: whether the mark point a21 is in the image photographed by the CCD camera 51 is judged, if yes, the correction cutting step and the feeding step are performed again; if not, the feeding step is performed;

[0089] The feeding step: the first moving assembly 22 drives the material carrying cutting table 21 to return to the initial position 201;

[0090] The discharging step: the discharging carrying assembly 42 carries the cut material b on the material carrying cutting table 21 and places it on the discharging table 41;

[0091] The total cycle cutting step: the feeding step to the discharging step are cyclically performed.

[0092] Specifically, in the preset step, the production process can quickly adapt to different batch sizes and size specifications of the film through parameter setting (such as the feeding distance, the initial height threshold). The correction cutting step adopts a closed-loop visual control strategy to realize accurate alignment and high-precision cutting. The sub-cycle step intelligently judges whether to continue cutting according to the mark point a21 image information, forming an efficient closed-loop production mode. Furthermore, the method significantly reduces manual intervention through the orderly series of a series of automatic steps. The combination of CCD positioning, automatic feeding and cycle mode makes the production process more continuous, efficient and accurate, not only reducing labor costs and labor intensity, but also stably improving the production line capacity and product quality.

[0093] In another embodiment, a vehicle-mounted film automatic cutting method comprises the following steps:

[0099] Material judging step: judge whether there is the mark point a21 in the image shot by the CCD camera 51, if yes, execute the correction punching step; if no, judge whether the feeding step has been executed, if yes, execute the empty material warning step (indicating that there is no material on the empty material warning plate 311 at this time, and the empty material warning plate 311 is carried on the material carrying punching table 21 in the feeding step, instead of the material to be punched a, so even if the material carrying punching table 21 enters the punching position 101, the CCD camera 51 cannot shoot the mark point a21);

[0100] Correction punching step: judge whether the position of the mark point a21 coincides with the positioning reference point 53, if no, control the material carrying punching table 21 to move by the feeding mechanism 2 until the mark point a21 coincides with the positioning reference point 53; if yes, control the punching head 11 to punch the material to be punched a on the punching position 101 by the punching mechanism 1;

[0101] Feeding step: after executing the correction punching step, drive the material carrying punching table 21 to move by 1 unit of feeding distance away from the initial position 201 by the first transfer assembly 22; accumulate the feeding number, and judge whether the current feeding number reaches the feeding number threshold, if no, execute the sub-cycle punching step, if yes, execute the material returning step;

[0102] Sub-cycle cutting step: again perform the material judgment step, correction cutting step and feeding step;

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

[0104] Material discharge step: the material discharge assembly 42 carries the cut material b on the material cutting table 21 and places it on the material discharge table 41;

[0105] Total cycle cutting step: cyclically perform the material feeding step to the material discharge step;

[0106] Empty material warning step: issue an empty material warning to warn of empty material, and stop performing the total cycle cutting step. The specific warning method can use the display screen 52 of the CCD mechanism 5 to display an empty material warning, or a buzzer to issue an empty material warning sound, or an empty material warning light to light up. Specifically, the feeding number threshold is matched with the number of holes or shapes to be cut on the film by pre-calculation. The material judgment step ensures that the next round of accurate positioning and cutting is only performed when there is still an area to be cut 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 cut a. When the feeding has been performed but no mark point a21 appears, it 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 number of cuttable films, the production process is more intelligent. This method ensures that all cutting tasks of each film are completed without waste, reducing unnecessary time consumption and actions, thereby improving automation efficiency and economic benefits. By adding an 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.

[0107] Another embodiment, as Figure 4As shown, the feeding step further includes: in the lifting process of the feeding and conveying assembly 32 conveying the to-be-punched material a, the top edge of the to-be-punched material a is scraped by the anti-adhesion prong 312a, and due to the sheet structure of the to-be-punched material a, the edge of the to-be-punched material a is bent to a certain extent, thereby preventing two or more to-be-punched materials a from being adhered together and affecting the subsequent punching action. Specifically, when two or more to-be-punched materials a are adhered together, the adhered to-be-punched material a is lifted in the conveying process, and due to the scraping of the anti-adhesion prong 312a, the edge of the to-be-punched material a is bent to a certain extent, thereby causing the bottom adhered other to-be-punched material a 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 stacked sheets are effectively separated, reducing the positioning error, punching failure or equipment jam caused by multiple film 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.

[0108] A vehicle-mounted film production method for producing a vehicle-mounted film by using the vehicle-mounted film automatic punching device according to any one of the preceding embodiments, the method comprising the steps of the vehicle-mounted film automatic punching method according to any one of the preceding embodiments.

[0109] As Figures 11 to 13 shown, a variable-distance unloading suction assembly is provided in the embodiment of the utility model, comprising: a mounting plate 81, an unloading negative pressure suction nozzle 4221, a variable-distance plate 83 and a variable-distance driving mechanism 84. Wherein:

[0110] The mounting plate 81 is provided with a variable-distance horizontal guide rail 811 and a suction nozzle mounting block 811a movably mounted on the variable-distance horizontal guide rail 811, and the suction nozzle mounting block 811a is provided with a variable-distance guide convex 811b;

[0111] The unloading negative pressure suction nozzle 4221 is mounted on the suction nozzle mounting block 811a and is provided with at least two unloading negative pressure suction nozzles 4221, at least one unloading negative pressure suction nozzle 4221 in the at least two unloading negative pressure suction nozzles 4221 is used for suctioning the punched film b1, and at least one unloading negative pressure suction nozzle 4221 in the remaining unloading negative pressure suction nozzles 4221 is used for suctioning the corner waste b2;

[0112] The variable-distance plate 83 is provided with a variable-distance guide groove 831 into which the variable-distance guide convex 811b is inserted;

[0113] The variable-distance driving mechanism 84 is used for driving the variable-distance plate 83 to lift.

[0114] Specifically, although the positions of the film material before and after punching on the loading and punching table 21 do not change substantially, the punched film b1 and the corner waste b2 formed by the film material after punching, i.e., the punched material b, are separated from each other, resulting in the need for step-by-step unloading, i.e., the punched film b1 and the corner waste b2 are unloaded in sequence, which is cumbersome and inconvenient. In order to achieve one-time unloading and avoid step-by-step unloading, at least two unloading negative pressure nozzles 4221 need to be provided on the unloading suction accessory 422 to respectively suction the punched film b1 and the corner waste b2. Since the punching device needs to replace film materials of different sizes for punching, the distance between the at least two unloading negative pressure nozzles 4221 needs to be adjustable, i.e., the distance between the two adjacent unloading negative pressure nozzles 4221 can be changed to adapt to the punching of the to-be-punched material a of different sizes, so that the punched material b formed by the to-be-punched material a of different sizes after punching can still be unloaded one time, avoiding the adverse effects caused by step-by-step unloading. In the scheme, the variable distance plate 83 is driven to rise and fall by the variable distance driving mechanism 84, so that the multiple variable distance guide grooves 831 on the variable distance plate 83 guide the matching variable distance guide convexes 811b, and then any two adjacent variable distance guide convexes 811b approach or move away from each other as the variable distance plate 83 rises and falls. Any two adjacent suction nozzle mounting blocks 811a also approach or move away from each other synchronously, and each suction nozzle mounting block 811a is provided with a corresponding unloading negative pressure nozzle 4221. Therefore, the two adjacent unloading negative pressure nozzles 4221 also approach or move away from each other synchronously, and finally the distance between the two unloading negative pressure nozzles 4221 is changed, so that the punching and unloading of the film material of different sizes can be better adapted.
