[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Combined with the background technology, it can be seen that some aluminum foil cutting equipment is not designed with an effective collection structure to collect the cut aluminum foil, resulting in a large amount of manpower required to carry out this collection work. This not only increases the labor intensity of technicians, but also is not conducive to improving the industrial production efficiency of aluminum electrolytic capacitors.

[0037] To this end, the utility model proposes an aluminum foil cutting device, which is suitable for basic cutting work of aluminum foil substrates used in aluminum electrolytic capacitors (i.e. cutting large-sized aluminum foil substrates into small pieces of aluminum foil, which are hereinafter referred to as aluminum foil sheets).

[0038] See also Figure 1 The aluminum foil cutting device provided by the embodiment of the present invention includes a base 10, and a feeding mechanism 20, a pressing mechanism 30, a cutting mechanism 40 and a receiving mechanism 50 arranged on the base 10 in sequence along the conveying direction (or feeding direction) of the aluminum foil substrate. Specifically:

[0039] The distance between the edge pressing mechanism 30 and the cutting mechanism 40 can be adjusted, and the edge pressing mechanism 30 is used to press and guide both sides of the aluminum foil substrate in the width direction (perpendicular to the conveying direction);

[0040] The material receiving mechanism 50 includes a translation drive structure 500, a material box 501 and a guide roller 503. The material box 501 is movably mounted on the base 10 and connected to the driving end of the translation drive structure 500. The guide roller 503 is disposed above the material box 501.

[0041] The cutting mechanism 40 includes a detection structure 403 located above the material box 501. The detection structure 403 is electrically connected to the translation drive structure 500 and has a detection and counting function to count the number of aluminum foil sheets cut.

[0042] According to the aluminum foil cutting device of the present embodiment, its feed mechanism 20 feeds a rolled aluminum foil substrate into a press mechanism 30, which then uses the press mechanism 30 to press and guide the aluminum foil substrate, allowing it to enter the cutting mechanism 40 smoothly and accurately. After passing through the cutting mechanism 40, the ends of the aluminum foil substrate are guided by guide rollers 503 and bent toward the magazine 501. After the cutting mechanism 40 completes the slitting, the resulting aluminum foil sheets accurately fall into the magazine 501. During this slitting process, the cutting mechanism 40 can detect and count the resulting aluminum foil sheets using a detection structure 403.

[0043] Obviously, the aluminum foil cutting device provided by the embodiment of the present invention can realize the automatic collection of aluminum foil sheets and effectively count their quantity, thereby fully replacing the manual collection of aluminum foil sheets, thereby achieving the purpose of improving the production efficiency of aluminum electrolytic capacitors.

[0044] The detection structure 403 used in the embodiment of the present invention is electrically connected to the translation drive structure 500. Through its detection and counting function, it can cooperate with the translation drive structure 500 to realize multiple working modes. For example, the first working mode is to simply count the aluminum foil sheets obtained by cutting, and display the counted number through a display screen, voice broadcast or Bluetooth transmission, so that the technician can determine how many aluminum foil sheets are cut, manually stop the machine and remove the aluminum foil sheets (or control the translation drive structure 500 to move the material box 501 to a position convenient for removing the aluminum foil sheets after stopping); the second working mode is to set the aluminum foil cutting device to automatically stop feeding and cutting when the detection count of the detection structure 403 reaches N (N is a positive integer greater than zero), and at the same time, the translation drive structure 500 moves the material box 501 to a position convenient for removing the aluminum foil sheets. In this way, the electrical connection between the detection structure 403 and the translation drive structure 500 can be used to realize automatic counting and discharging of aluminum foil sheets.

[0045] Obviously, no matter the first working mode or the second working mode, the number of aluminum foil pieces can be counted while they are being collected, so as to improve the production efficiency of the aluminum foil cutting work.

[0046] It can be understood that the implementation of the electrical connection working form between the detection structure 403 and the translation drive structure 500 needs to be further electrically connected to the factory's host computer, the control terminal of the production line or the controller equipped with the aluminum foil cutting device itself, so as to perform automated production according to the actual working mode required.

[0047] In a further embodiment of the present invention, detection structure 403 can utilize a commonly used falling material counting sensor or thickness detection sensor in conjunction with a corresponding control program to fully utilize the detection and counting functions required for production. (When using a thickness detection sensor, the thickness detection sensor can be set to feedback a detection signal when the stack height of the aluminum foil sheets reaches a set height. The number of aluminum foil sheets corresponding to the set height is the count control quantity required for production.)

[0048] Please also refer to Figure 1 、 Figure 3In some embodiments of the present invention, the material receiving mechanism 50 further includes a bracket 502, which is located on a side of the material box 501 away from the cutting mechanism 40. The bracket 502 is movably connected to the material box 501 and / or the driving end of the translation drive structure 500. The guide roller 503 is rotatably mounted on the bracket 502. Obviously, whether the bracket 502 is connected to the material box 501 or the driving end of the translation drive structure 500, the translation movement is achieved by the movement of the driving end of the translation drive structure 500, thereby enabling the guide roller 503 to translate synchronously with the material box 501, thereby avoiding the need to repeatedly adjust the guide position of the guide roller 503 after the material box 501 moves and resets.

[0049] Please refer again Figure 3 In a further embodiment of the present invention, a rotatable and adjustable mounting base is connected to the bracket 502, and the mounting base has a mounting position adapted to the guide roller 503; the mounting position can rotate away from the material box 501 or rotate closer to the material box 501 as the mounting base rotates.

[0050] It is understood that the rotational adjustment between the mounting base and the bracket 502 can be achieved by a rotational connection via a rotating shaft, and the rotating shaft has rotational damping during rotation. This provides damped rotational adjustment, allowing the mounting base to remain relatively fixed at any rotational position, thereby allowing the guide roller 503 to perform its guiding function at the actual desired position.

[0051] Please refer again Figure 1 In a further embodiment of the present invention, the magazine 501 has a removable drawer, and both the magazine 501 and the drawer are open structures with top openings, so that the aluminum foil can be smoothly dropped in. On this basis, if multiple drawers of the same specifications are used as a finished product storage box, each drawer containing aluminum foil can be directly packaged and sealed before being sent to the next process or stored in a warehouse.

[0052] Furthermore, the end of the material box 501 away from the cutting mechanism 40 is higher than the end close to the cutting mechanism 40, thereby forming a blocking portion relative to the discharge port of the cutting mechanism 40, and then cooperating with the guide roller 503 to bend and guide the end of the aluminum foil substrate.

[0053] Optionally, the end of the blocking portion corresponding to the cutting mechanism 40 is preset as a sloped surface to facilitate bending of the aluminum foil and rapid sliding after slitting. On this basis, the driving end of the translation drive structure 500 is hinged to the end of the blocking portion away from the cutting mechanism 40.

[0054] In some embodiments of the present invention, the translation drive structure 500 can be implemented by a horizontally or tilted telescopic cylinder, and the telescopic end of the telescopic cylinder is connected to the material box 501, so that the material box 501 can be controlled to translate by the telescopic adjustment of the telescopic cylinder.

[0055] Please refer again Figure 1 and Figure 3 In some embodiments of the present invention, the cutting mechanism 40 includes a mounting frame 400, a slitting structure 401 and a blowing structure 402, and the mounting frame 400 is arranged on the base 10; the slitting structure 401 and the blowing structure 402 are fixed on the mounting frame 400, and the blowing structure 402 is located below the slitting structure 401; the blowing structure 402 has a blowing surface facing the material box 501.

[0056] It is understood that when the blowing surface of the blowing structure 402 is facing the material box 501, its blowing direction is preferably aligned with the end of the aluminum foil substrate to be cut. This allows the blowing structure 402 to blow air in time after the cutting operation is completed, so that the cut aluminum foil sheets are quickly separated and fall into the material box 501.

[0057] Obviously, the blowing structure 402 can provide a plurality of blowing holes in a row on the blowing surface connected to the air source or provide a plurality of blowing nozzles connected to the air source, thereby exerting the blowing and blanking function.

[0058] In some embodiments of the present invention, the blowing angle of the blowing surface can be adjusted to facilitate debugging to obtain a suitable blowing direction and improve the blanking and collection efficiency of the aluminum foil.

[0059] It is understandable that the blowing angle adjustment of the blowing surface can be implemented by rotating the blowing structure 402, that is, the blowing structure 402 is set to be rotatable on the mounting frame 400, and the blowing angle can be adjusted by rotating the blowing structure 402 as a whole.

[0060] See also Figure 4 In some embodiments of the present invention, a plurality of evenly distributed friction protrusions 5030 are provided on the circumferential surface of the guide roller 503 to increase the friction between the guide roller 503 and the aluminum foil, thereby enabling the aluminum foil substrate to be fully guided and bent by the guide roller 503.

[0061] Please refer to Figure 1 、 Figure 2 and Figure 5In some embodiments of the present invention, the edge pressing mechanism 30 includes a fixed frame 300 and a downward pressing structure 301. The fixed frame 300 is movably and adjustably arranged on the base 10. The downward pressing structure 301 is provided in two groups and distributed at both ends of the fixed frame 300. Each downward pressing structure 301 has a movable end that can be raised and lowered. In the specific working process, after the end of the aluminum foil substrate is fed out through the feeding mechanism 20, its two sides move through the limiting openings formed between the movable ends of the downward pressing structure 301 and the end surface of the base 10. The thickness of the limiting openings is adapted to the thickness of the aluminum foil substrate. Obviously, the limiting openings on both sides cooperate with the base 10 to form a channel adapted to the aluminum foil substrate, thereby being able to limit and guide the aluminum foil substrate.

[0062] It is understood that the fixing frame 300 can be movably connected to the base 10 via guide rails and fixed by bolts or screws. Based on this, when the fixing frame 300 is moved and adjusted, the distance between the edge pressing mechanism 30 and the cutting mechanism 40 can be adjusted, thereby facilitating technicians to adjust the distance according to actual needs (for example, the smaller the distance, the better the tensioning effect during the conveyance of the aluminum foil substrate).

[0063] In a further embodiment of the present invention, the lower end surface of the movable end is provided with a plurality of rollers or pressing blocks, so as to facilitate the flattening of the side edges of the aluminum foil substrate by the rollers or pressing blocks.

[0064] Optionally, multiple groups of edge pressing mechanisms 30 can be provided along the conveying direction of the aluminum foil substrate to further improve the leveling and conveying effect of the aluminum foil substrate.

[0065] Optionally, the edge-holding mechanism 30 further includes a dust cover 302 mounted on the fixing frame 300. The dust cover 302 is a protective cover structure with an open bottom, the edge of which is parallel to the end face of the base 10. The downward pressing structure 301 is disposed within the opening to prevent dust and debris from becoming lodged between the downward pressing structure 301 and the aluminum foil substrate.

[0066] Please refer again Figure 1 In some embodiments of the present invention, the feeding mechanism 20 includes a feeding terminal 200 and a feeding roller group 201, and the distance between the feeding terminal 200 and the feeding roller group 201 can be adjusted.

[0067] Obviously, the spacing adjustment between the discharge terminal 200 and the feed roller group 201 can also be implemented by the movable setting of the above-mentioned fixed frame 300, so as to achieve spacing adjustment by adjusting the fixed position of the discharge terminal 200 and / or the feed roller group 201, thereby achieving the adjustment of the tension degree of the aluminum foil substrate during the transportation process.

[0068] Please refer again Figure 1In some embodiments of the present invention, the base 10 includes a linear motor 101 and a base plate 100. The feeding mechanism 20, the edge holding mechanism 30, the cutting mechanism 40, and the receiving mechanism 50 are sequentially arranged on the upper end surface of the base plate 100. Two sets of linear motors 101 are provided and located on both sides of the base plate 100. The edge holding mechanism 30 is located between the two sets of linear motors 101. The fixed frame 300 of the edge holding mechanism 30 is connected to the movable end of the linear motor 101. As a result, the fixed frame 300 can be controlled by the movable end of the linear motor 101 to move and adjust, thereby achieving automatic adjustment of the distance between the edge holding mechanism 30 and the cutting mechanism 40.

[0069] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
