1 to 3 , the copper foil lead wire cutting device for a foil winding transformer according to an embodiment of the utility model comprises: a machine table 10 , at least one pressing assembly 20 , a clamping assembly 30 and a limiting assembly 40 . A movable tool 11 is provided at one end edge of the machine table 10, and the cutting position of the tool 11 coincides with one end face of the machine table 10, and the tool 11 is used to cut the copper foil; a clamping assembly 20 is provided on the machine table 10 and located at one side edge of the machine table 10, and the clamping assembly 20 is used to clamp the copper foil on one side edge of the machine table 10; a cardboard assembly 30 is provided on the machine table 10 and located at the edge of the machine table 10, and the cardboard assembly 30 includes a first cardboard 31, and the first cardboard 31 is adjustably provided on one side of the machine table 10, and one side of the first cardboard 31 can abut against one side of the copper foil; a limit assembly 40 is movably provided on one side of the machine table 10, and the upper end of the limit assembly 40 can abut against the top of the tool 11, and the limit assembly 40 is used to limit the falling position of the tool 11.

Specifically, as shown in the figure, a rotating cutter 11 is provided at the rear end of the machine 10, and the cutter 11 is located at the left edge of the machine 10, so the position where the cutter 11 falls is the left end face of the machine 10, and the copper foil to be cut is placed on the left edge of the machine 10 and part of it protrudes from the left edge of the machine 10, and when the cutter 11 rotates and falls, the copper foil lead can be cut on the copper foil. In addition, a clamping assembly 20 is also provided on the side where the copper foil is placed, and the clamping assembly 20 can be used to clamp the copper foil on the machine 10, which is convenient for the cutting of the cutter 11. It can be imagined that one side of the first clamping plate 31 in the clamping plate assembly 30 can be against one side of the copper foil, so that the position of the copper foil can be quickly located, that is, the position of the other side of the copper foil is located, and then the cutting position on the copper foil can be quickly located. It is also conceivable that the limit assembly 40 can move forward and backward along the machine table 10, thereby changing the position of the limit assembly 40 against the tool 11, thereby controlling the rotation and falling position of the tool 11, and thereby controlling the cutting length of the copper foil cut by the tool 11, that is, the length of the copper foil lead.

The copper foil is placed on one side edge of the machine 10, and part of the copper foil protrudes from one side edge of the machine 10, and the movable cutter 11 can move on the cutting position of the cutter 11, so that the copper foil lead can be cut on the copper foil. Before cutting, the side of the first card plate 31 of the card plate assembly 30 can be used to quickly push against one side of the copper foil, so that the width of the part of the copper foil protruding from one side edge of the machine 10 can be quickly determined, and the position to be cut can be quickly determined, so as to facilitate the cutting of the cutter 11. In addition, the copper foil can be pressed on the machine 10 by the clamping assembly 20 to prevent the copper foil position from moving and causing the cutting position of the copper foil to change. Furthermore, the limit assembly 40 can push against the top of the cutter 11 through its own upper end, so that the falling position of the cutter 11 can be limited without affecting the falling cutting of the cutter 11, thereby ensuring the length of the cut copper foil lead. Therefore, in summary, the copper foil lead wire cutting device of the foil winding transformer can quickly cut out the through copper foil lead wires that meet the length and width requirements, and can also ensure that the accuracy of each copper foil lead wire meets the requirements.

Referring to FIG. 4 , in some embodiments of the utility model, specifically, a waist-shaped hole 311 may be provided on the first cardboard 31, and the first cardboard 31 may be adjusted in position through the waist-shaped hole 311. The first cardboard 31 may be fastened to the machine 10 by a fastening screw (not shown in the figure). When the cutting width needs to be adjusted, the fastening screw may be loosened to release the first cardboard 31, so that the first cardboard 31 moves along the direction of the waist-shaped hole 311, thereby changing the distance between the left side of the first cardboard 31 and the left end face of the machine 10 according to the cutting amount requirement, thereby determining the width of the cut copper foil lead. It should be noted that in order to quickly determine the above-mentioned distance, a standard caliper may be placed on the left side of the first cardboard 31, the left side of the standard caliper may be aligned with the left end face of the left side of the machine 10, and the left side of the first cardboard 31 may be close to the right side of the standard caliper, so that the position of the first cardboard 31 can be located.

3 and 4, in some embodiments of the present invention, further, the card assembly 30 further includes a second card 32, which is disposed at one end of the machine 10, and one end of the copper foil can be pressed against one side of the second card 32. The second card 32 is located at the rear end of the machine 10, and the left end of the second card 32 is flush with the left end surface of the machine 10, so that the cut end of the copper foil can be pressed against the front side of the second card 32 to achieve rapid positioning of the copper foil in the front and rear directions.

Referring to FIG. 1 , in some embodiments of the present invention, specifically, the limit assembly 40 includes a limit block 41 and a fastener (not shown in the figure), the lower end of the limit block 41 is movably disposed in the slide groove 12 at the side end of the machine table 10, and the fastener is used to fasten the limit block 41 in the slide groove 12, and the top of the tool 11 is provided with a boss 111, and the top of the limit block 41 can abut against the lower end of the boss 111. The fastener can be a fastening screw, and the fastener is disposed at the lower end of the limit block 41, so that the lower end of the limit block 41 can be fastened in the slide groove 12 of the machine table 10, and when the fastener is loosened, the limit block 41 can be released, so that the limit block 41 can move along the front and rear direction of the slide groove 12. If the stop block 41 moves toward the rear end of the machine 10, the stop block 41 is closer to the rotation center of the cutter 11, that is, the top of the stop block 41 is closer to the root of the cutter 11, so it can be imagined that the falling distance of the cutter 11 will become smaller, that is, the length of the copper foil cut by the cutter 11 will be shorter; on the contrary, if the stop block 41 moves toward the front end of the machine 10, the stop block 41 is farther away from the rotation center of the cutter 11, that is, the top of the stop block 41 is farther away from the root of the cutter 11, so it can be imagined that the falling distance of the cutter 11 will become larger, that is, the length of the copper foil cut by the cutter 11 will be longer. Therefore, it can be understood that by changing the position of the stop block 41, the length of the copper foil cut by the cutter 11 can be controlled, and copper foil leads of different lengths can be obtained.

Further, referring to FIG. 1 , in some embodiments of the present invention, the middle portion of the stop block 41 has a recessed portion 411, and the recessed portion 411 is used to avoid the copper foil. When the copper foil protrudes from the left edge of the machine 10 and becomes larger, the copper foil protruding from the edge of the machine 10 can be avoided by the recessed portion 411 on the stop block 41.

Furthermore, in some embodiments of the present invention, a scale is provided on the first card board 31. The length of the copper foil lead cut by the cutter 11 can be clearly observed according to the scale on the first card board 31, which can facilitate the technician to make length adjustments.

4 to 5, in some embodiments of the present invention, the clamping assembly 20 includes a support 21, a handle 22 and a clamping member 23.

Specifically, the handle 22 is rotatably connected to the lower half of the support 21 through the first connecting rod 221, and the handle 22 can be flipped along the left and right directions on the support 21. Therefore, when the handle 22 flips to the left, it drives the first connecting rod 221 to flip to the left, thereby driving the third connecting rod 232 connected in the middle to move to the left, and then pushes the second connecting rod 231 connected to the other end of the third connecting rod 232 to flip to the left at the connection point on the support 21. When the second connecting rod 231 flips to the left, it drives the third connecting rod 232 to move toward the lower left at the same time, and finally presses the second connecting rod 231 downward, and finally drives the clamping piece 23 connected at one end of the second connecting rod 231 to press the copper foil on the machine table 10 downward, and finally achieves the purpose of the clamping piece 23 pressing the copper foil downward by flipping the handle 22 left and right.

In some embodiments of the present invention, the pressing member 23 and the second connecting rod 231 are further arranged perpendicular to each other. When the second connecting rod 231 flips to the left, the third connecting rod 232 is driven to move to the lower left at the same time, and finally the second connecting rod 231 is pressed downward, and the second connecting rod 231 can be pressed to a horizontal state, so that the pressing member 23 is in a vertical state, so that the pressing force of the pressing member 23 is vertically downward, and the pressing member 23 can be prevented from slipping when pressing the copper foil, thereby causing cutting errors.

5, in some embodiments of the present invention, a protective member 233 is provided at the lower end of the pressing member 23, and the protective member 233 contacts the copper foil. The protective member 233 can be an elastic rubber member or a soft cotton cloth, etc., which can prevent the pressing member 23 from damaging the copper foil during the pressing process.

1 , in some embodiments of the present invention, two pressing assemblies 20 are provided, and the two pressing members 23 can be arranged on one side edge of the machine table 10. The pressing assemblies 20 arranged on one side edge of the machine table 10 can press the copper foil at multiple locations, so that the copper foil is close to the machine table 10, which is convenient for cutting by the tool 11.

The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
