[0002] In the automatic production line of vehicle-mounted diaphragm and other sheet materials, multiple pieces or a stack of materials are often reliably carried and gradually supplied to the next process. Traditional feeding devices usually use simple feeding table lifting mechanical brackets, which not only require frequent personnel operation, but also are prone to problems such as sliding, jamming or overturning when the load is unbalanced or the amount of material is large, affecting overall efficiency and safety. Especially when a large number of batch continuous feeding is required, stable, controllable and labor-saving automatic feeding methods are more important. SUMMARY

[0014] As a further scheme of the present application, the vehicle-mounted diaphragm automatic feeder further comprises:

[0015] The feeding rack has a standby material position and a feeding position.

[0016] The feeding line is used to move the material loading tray to the standby material position.

[0017] The feeding lifting mechanism is installed on the feeding rack and is used to move the material loading tray from the standby material position to the feeding position by lifting the one-way clamping assembly.

[0018] As a further scheme of the present application, the clamping part, the limiting clamping part and the return spring each have at least two.

[0019] As a further scheme of the present application, the one-way clamping assembly has two, one of which is used to lift one side of the bottom of the material loading tray, and the other is used to lift the other side of the bottom of the material loading tray.

When the lifting mechanism rises again, the reset spring and the limiting convex promote the supporting and limiting parts to restore the maximum angle of expansion, automatically resisting the edge of the bottom of the material tray, completing the automatic feeding process. This automatic clamping and reset mechanism reduces the dependence on manual operation, improves the efficiency and reliability of feeding.

[0031] 3. Simple structure and efficient operation: The one-way supporting and clamping assembly is composed of a supporting part, a limiting part, a limiting part and a reset spring, with simple structure design, small space occupation, easy manufacturing and maintenance. Its automatic clamping and reset function adapts to high-frequency lifting action, suitable for large batch continuous feeding demand, significantly improving the automation level and overall production efficiency of the production line, while reducing labor intensity and equipment failure rate.

[0049] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. It can be understood that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for clear description, and does not limit the connection mode.

[0050] The utility model discloses a kind of vehicle-mounted diaphragm automatic punching devices and methods for the deficiencies of prior art, specifically aims at providing a kind of vehicle-mounted diaphragm automatic punching device integrated with automatic feeding, automatic feeding and accurate positioning and punching.The device has highly automated and intelligent features, through accurate visual inspection (CCD monitoring) and controllable feeding mechanism 2, it can be quickly and accurately conveyed and positioned to punching position 101 for the material to be punched a, so as to significantly reduce the uncertainty caused by human operation while improving processing accuracy and efficiency.

[0051] As Figures 1-10 Indicated, in the utility model embodiment provides a kind of vehicle-mounted diaphragm automatic punching device, comprising: punching mechanism 1, feeding mechanism 2, feeding mechanism 3, discharging mechanism 4 and punching control mechanism.Wherein:

[0052] Punching mechanism 1 has punching head 11 and punching position 101 arranged at the bottom of punching head 11;Optionally, punching mechanism 1 can include hydraulic or pneumatic drive assembly, realize the stable depression of punching head 11.

[0053] Feeding mechanism 2 includes material carrying punching table 21 and first transfer assembly 22 for driving material carrying punching table 21 to enter and exit punching position 101;Optionally, the first transfer assembly 22 of feeding mechanism 2 can be linear slide, ball screw or servo motor driven guide rail structure, to ensure that material table enters and exits punching area smoothly and accurately.

[0054] Feeding mechanism 3 includes feeding table 31 and feeding handling assembly 32 for carrying the material to be punched a on feeding table 31 to material carrying punching table 21;Optionally, feeding handling assembly 32 can be equipped with vacuum chuck or mechanical clamp to prevent material from slipping and position deviation.

[0055] Discharging mechanism 4 includes discharging table 41 and discharging handling assembly 42 for carrying the punched material b on material carrying punching table 21 to discharging table 41;Optionally, discharging handling assembly 42 can also be equipped with suitable vacuum chuck or mechanical clamp jaw for automatic picking and placing of finished product or waste material.

[0056] Punching control mechanism is connected with punching mechanism 1, for controlling punching mechanism 1 to drive punching head 11 to punch when the material to be punched a on material carrying punching table 21 is located in punching position 101. Optionally, punching control mechanism can realize data communication with sensor, PLC control unit or industrial computer, so that the system automatically triggers punching action according to material positioning signal.

[0057] Through the above structure, each mechanism cooperates with each other to realize full automation of the diaphragm from feeding, feeding, punching to discharging. The scheme effectively avoids the low efficiency and positioning error caused by manual multiple alignment and handling, makes the production process more efficient and stable, and improves the consistency of product quality and processing precision.

[0058] In one embodiment, the punching control mechanism is a CCD mechanism 5, which includes a CCD camera 51 facing the punching position 101, and is used to determine whether the material is located at the punching position 101 according to the image captured by the CCD camera 51, and if so, control the punching mechanism 1 to drive the punching head 11 to perform the punching action. Optionally, the CCD camera 51 is an industrial high-speed camera that can achieve high resolution and fast imaging.

[0059] 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 table 21 to switch and move between the initial position 201 and the punching position 101; the feeding handling assembly 32 is used to carry the material to be punched a on the feeding table 31 to the material carrying punching table 21 located at the initial position 201; and the discharging handling assembly 42 is used to carry the punched material b on the material carrying punching table 21 located at the initial position 201 to the discharging table 41.

[0060] The material to be punched a is provided with a mark point a21 captured by the 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 control the punching mechanism 1 to punch the material to be punched 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 motion between the initial position 201 and the punching position 101, after completing the punching of one diaphragm, it can quickly return to the initial position 201, so as to carry out the discharging and the next material feeding action. 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 punching precision. The CCD visual guidance significantly reduces the processing position error, without manual intervention, thereby improving the automation degree of the production line and the yield of finished products.

[0061] 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 for capturing 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, which 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 double directions (X, Y) enables the device not only to accurately adjust the front and back positions of the material in the punching position 101, but also to accurately correct the left and right directions, thereby realizing the 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.

[0062] 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 being 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 rays 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.

[0063] 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.

[0064] 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 sheet. Furthermore, 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, so that the automation and stability of the production line are further improved.

[0065] In another embodiment, as shown in Figure 8 The to-be-cut material a comprises at least one to-be-cut film sheet 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 sheet 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.

[0066] 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 sheet a1, and the other feeding negative pressure suction nozzle 3221 is used for adsorbing the positioning edge material a2; specifically, during feeding, the film sheet and the positioning edge material a2 can be synchronously grabbed through multi-nozzle partition adsorption, so as to avoid mispositioning of the two.

[0067] 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 sheet 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. Furthermore, through the multi-nozzle adsorption mode with clear division of labor, synchronous carrying of the to-be-cut film sheet a1 and the positioning reference component is realized, and sorting of the finished product and the waste is realized during discharging. This can simplify the subsequent sorting process, reduce the risk of mixing materials, and improve the automation and efficiency of the whole production line.

[0068] In another embodiment, as shown in Figure 4 The vehicle-mounted film sheet automatic cutting device further comprises an empty material warning plate 311 and an anti-adhesion piece 312. Wherein:

[0069] 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.

[0070] 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.

[0071] The material carrying punching table 21 is configured 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.

[0072] In another embodiment, a vehicle-mounted film piece automatic punching method includes the following steps:

[0073] 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;

[0074] 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;

[0075] 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;

[0076] 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;

[0077] The feeding step: the first moving assembly 22 drives the material carrying cutting table 21 to enter the cutting position 101;

[0078] 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;

[0079] 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;

[0080] The sub-cycle cutting step: whether there is a mark point a21 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;

[0081] The feeding step: the first moving assembly 22 drives the material carrying cutting table 21 to return to the initial position 201;

[0082] 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;

[0083] The total cycle cutting step: the feeding step to the discharging step are cyclically performed.

[0084] 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.

[0085] In another embodiment, a vehicle-mounted film automatic cutting method comprises the following steps:

[0086] Presetting step: set the mark point a21 shot by the CCD camera 51 to obtain the material to be punched a, and preset the positioning reference point in the area shot by the CCD camera 51; preset the initial height threshold of the feeding table 31 according to the maximum lifting stroke of the feeding suction accessory 322; preset the feeding distance of 1 unit in the feeding step; preset the feeding number threshold matched with the number of the film pieces a1 to be punched on the material to be punched a; and place the empty material warning plate 311 on the feeding table 31.

[0087] Loading step: place the stacked material to be punched a formed by stacking at least two materials to be punched a on the empty material warning plate 311.

[0088] Initialization step: control the feeding table 31 to stop after lifting to the initial height threshold by the photoelectric switch of the lifting control assembly 34, so as to avoid lifting beyond the predetermined lifting stroke, and drive the material carrying punching table 21 to move to the initial position 201 by the first transfer assembly 22.

[0089] Feeding step: carry the material to be punched a on the empty material warning plate 311 by the feeding handling assembly 32 and place it on the material carrying punching table 21, and suck the material to be punched a by the negative pressure suction assembly.

[0090] Feeding step: drive the material carrying punching table 21 to enter the punching position 101 by the first transfer assembly 22.

[0091] 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).

[0092] 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 until the mark point a21 coincides with the positioning reference point 53 by the feeding mechanism 2; 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.

[0093] Feeding step: after executing the correction punching step, drive the material carrying punching table 21 to move away from the initial position 201 by 1 unit of feeding distance 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.

[0094] Sub-cycle cutting step: again perform the material judgment step, correction cutting step and feeding step;

[0095] Material returning step: the first transfer assembly 22 drives the material cutting table 21 to return to the initial position 201;

[0096] Material discharging step: the material discharging assembly 42 carries the cut material b on the material cutting table 21 and places it on the discharging table 41;

[0097] Total cycle cutting step: cyclically perform the feeding step to the discharging step;

[0098] Empty material warning step: issue an empty material warning information to warn of empty material, and stop performing the total cycle cutting step. The specific warning method can be to display the empty material warning on the display screen 52 of the CCD mechanism 5, or to issue an empty material warning sound through the buzzer, or to light up the empty material warning light. 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 means that there is no material. The empty material warning can be prompted through sound, light or screen display. Further, through the feeding number threshold related to the actual number of cuttable materials on the film, 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 the empty material warning plate 311 in the feeding area and using visual detection, when the material is exhausted, the equipment can automatically identify and issue a warning, avoiding idling and invalid production actions, improving equipment utilization and work safety. This prompting mechanism makes production management more efficient and maintenance more timely.

[0099] Another embodiment, as Figure 4As shown, the feeding step further includes: in the process of feeding and carrying the to-be-cut material a upward, the top edge of the to-be-cut material a passes through the anti-adhesion prong 312a, and due to the sheet structure of the to-be-cut material a, the edge of the to-be-cut material a is bent to a certain extent, thereby preventing two or more to-be-cut materials a from being adhered together and affecting the subsequent cutting. Specifically, when two or more to-be-cut materials a are adhered together, in the process of being carried upward, due to the scraping of the anti-adhesion prong 312a, the edge of the to-be-cut material a is bent to a certain extent, thereby causing the other to-be-cut material a adhered at the bottom to fall off. The anti-adhesion prong 312a can be made of a material that is resistant to wear and not easy to adhere to the material, such as Teflon or a special coated metal. The prong is set at a proper position and height, so that the material passing upward is slightly deformed, and the lower adhered material is pricked away. Further, through the slight intervention of the edge of the material, the potential adhered and stacked materials are effectively separated, and the positioning error, cutting failure or equipment jamming problem caused by the simultaneous taking out of multiple film sheets is reduced. 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.
