Description

Technical Field

[0001] This utility model relates to the field of conductive adhesive processing technology, and in particular to an anti-deformation strip cutting machine for conductive adhesive production. Background Technology

[0002] Conductive rubber strips, commonly known as zebra strips, are a material formed by alternating layers of conductive silicone and insulating silicone and then vulcanizing them. During the production and processing, they need to be cut into strips using a strip cutting machine.

[0003] Traditional strip cutting machines, such as the utility model patent with publication number CN219902301U, use a cutting and pressing method to cut strips. With this operation, since it is a contact cutting method, the blade applies a certain mechanical pressure to the conductive rubber strip when cutting. This pressure can easily cause the conductive rubber strip to deform during the cutting process, especially in the area where the blade contacts and cuts. This deformation may result in an uneven cut surface, so solving this problem needs to be considered. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-deformation strip cutting machine for conductive adhesive production. This strip cutting machine uses an electric heating wire for cutting, which effectively avoids deformation caused by cutting compared to the traditional blade cutting method. In addition, it can cut strips of different lengths according to requirements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-deformable strip cutting machine for producing conductive adhesive includes a base; a cutting mechanism comprising a U-shaped frame fixedly connected to the upper end of the base, a hydraulic rod mounted on the upper end of the horizontal part of the U-shaped frame, the telescopic end of the hydraulic rod penetrating the horizontal part of the U-shaped frame and fixedly connected to a U-shaped strip, and a heating wire installed between the two vertical parts of the U-shaped strip; a flow guiding mechanism comprising a rectangular cavity opened inside the base, a bidirectional threaded rod rotatably connected between the inner walls of the front and rear sides of the rectangular cavity, a sliding strip threaded to each of the two threaded ends of the bidirectional threaded rod, both sliding strips being slidably connected to the inner wall of the rectangular cavity, two strip-shaped openings symmetrically opened at the top of the rectangular cavity, two connecting rods symmetrically fixedly connected to the upper end of each sliding strip, the upper end of each connecting rod penetrating the corresponding strip-shaped opening and fixedly connected to a guide plate; and a driving mechanism for driving the bidirectional threaded rod to rotate.

[0007] Preferably, the drive mechanism includes a motor mounted on the rear side of the base, the output shaft of the motor extending into the interior of the rectangular cavity and fixedly connected to the rear end of a bidirectional threaded rod.

[0008] Preferably, the two threaded ends of the bidirectional threaded rod have opposite thread directions.

[0009] Preferably, the motor is a servo motor that can change its rotation direction.

[0010] Preferably, a strip-shaped groove is formed at the upper middle part of the base.

[0011] Preferably, the two guide plates on the right side are provided with through openings, and a slidable U-shaped sliding plate is provided through both through openings. The opposite sidewalls of the U-shaped sliding plate are fitted and slidably connected to the front and rear inner walls of the base. A scale strip is provided on the front side of the base.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] By starting the motor to drive the two sliding bars to move relative to each other, the positions of multiple guide plates can be adjusted to ensure that they fit tightly against conductive strips of different widths. The cutting length of the conductive strip can also be precisely set by adjusting the position of the U-shaped sliding plate, making the control of the cutting length more intuitive and accurate. In addition, an electric heating wire cutting method is also provided. Compared with the traditional cutting method, this method can effectively avoid deformation during cutting, which can result in an uneven cut surface. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A non-deformable strip cutting machine for producing conductive adhesive, comprising a base 1;

[0020] It also includes a cutting mechanism, which includes a U-shaped frame 2 fixedly connected to the upper end of the base 1. A hydraulic rod 3 is installed at the upper end of the horizontal part of the U-shaped frame 2. The telescopic end of the hydraulic rod 3 passes through the horizontal part of the U-shaped frame 2 and is fixedly connected to a U-shaped strip 4. An electric heating wire 5 is installed between the two vertical parts of the U-shaped strip 4. A strip groove 7 is opened at the upper end of the middle part of the base 1.

[0021] The system also includes a flow guiding mechanism, which includes a rectangular cavity 12 inside the base 1. A bidirectional threaded rod 13 is rotatably connected between the inner walls of the front and rear sides of the rectangular cavity 12. The two threaded ends of the bidirectional threaded rod 13 have opposite thread directions. Each threaded end of the bidirectional threaded rod 13 is threaded with a sliding strip 14. Both sliding strips 14 are slidably connected to the inner wall of the rectangular cavity 12. Two strip-shaped openings 8 are symmetrically opened at the top of the rectangular cavity 12. Two connecting rods 15 are symmetrically fixedly connected to the upper end of each sliding strip 14. The upper end of each connecting rod 15 passes through the corresponding strip-shaped opening 8 and is fixedly connected with a guide plate 16.

[0022] It also includes a drive mechanism for driving the bidirectional threaded rod 13 to rotate. The drive mechanism includes a motor 6 mounted on the rear side of the base 1. The output shaft of the motor 6 extends into the rectangular cavity 12 and is fixedly connected to the rear end of the bidirectional threaded rod 13. The motor 6 is a servo motor that can change the direction of rotation.

[0023] Among them, the two guide plates 16 on the right side are provided with through holes 11, and a sliding U-shaped sliding plate 9 is provided through both through holes 11. The opposite side walls of the U-shaped sliding plate 9 are in contact with the front and rear inner walls of the base 1 and are slidably connected. The front side of the base 1 is provided with a scale bar 10, and the zero mark of the scale bar 10 is flush with the heating wire 5. It should be noted that the opposite side walls of the U-shaped sliding plate 9 are provided with a damping layer, which makes it difficult to slide when no force is applied.

[0024] In this invention, based on the width of the conductive adhesive strip, the motor 6 is started, which allows the two sliding strips 14 to move relative to each other, thereby causing multiple guide plates 16 to move to adapt to the width of the conductive adhesive strip. This ensures that after the conductive adhesive strip is inserted, it just contacts and slides with the multiple guide plates 16. Then, the position of the U-shaped sliding plate 9 is adjusted according to the required cutting length, and finally, one end of the conductive adhesive strip contacts the left side of the U-shaped sliding plate 9. Then, the heating wire 5 and the hydraulic rod 3 are started to cut. Compared with traditional cutting methods, this cutting method can effectively avoid deformation during cutting.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
