Conductive foam generally needs to be cut by a cutting device during actual use.

[0003] In the prior art, conductive foam is generally cut by a hydraulic rod driving a blade or by laser. By cutting the conductive foam on the top surface of the base paper, the conductive foam is separated on the base paper. However, since the conductive foam in the prior art needs to use other cutting devices to cut the long-rolled conductive foam after cutting the conductive foam, the long-rolled conductive foam becomes sheet-shaped, resulting in the need to manually align the long-rolled conductive foam when cutting it with another device, resulting in low cutting accuracy.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0021] Please refer to Figures 1-4 , the present utility model discloses a conductive foam precision die-cutting device, including a workbench 1 and a transport groove 2. The transport groove 2 is opened on the top surface of the workbench 1. A support 3 is installed on the top surface of the workbench 1. A control rod 4 is installed on one side surface of the support 3. A deflection groove 5 is opened on one side surface of the control rod 4. A cutting knife 6 is installed in the deflection groove 5. A support frame 7 is installed on the top surface of the workbench 1. A hydraulic rod 8 is installed on the top surface of the support frame 7. A conveying assembly is installed on the top surface of the workbench 1. A cutting assembly is installed on one side surface of the control rod 4.

[0022] There are two supports 3, and the two supports 3 are equidistantly distributed on the top surface of the workbench 1. A control rod 4 is correspondingly distributed on one side surface of each support 3. The control rod 4 is rotatably connected to the support 3 in a movable manner. A deflection groove 5 is correspondingly distributed on one side surface of each control rod 4.

[0023] The outer surface of the cutting knife 6 is in movable contact with the inner walls of the two deflection grooves 5. One end of the hydraulic rod 8 extends from the top surface of the support frame 7 to its bottom surface, and the bottom surface of the hydraulic rod 8 is fixedly connected to the top surface of the cutting knife 6.

[0024] The cutting assembly includes a shear block 15. A cutting knife 16 is installed on one side surface of the control rod 4, and the shear block 15 is installed on one side surface of the workbench 1.

[0025] Both ends of the cutting knife 16 are fixedly connected to the two control rods 4 respectively, and the bottom surface of the cutting knife 16 is in movable contact with one side surface of the shear block 15.

[0026] When the hydraulic rod 8 continuously moves downward to cut the conductive foam and reaches a certain number of cutting times for the long roll of conductive foam, at this time, the hydraulic rod 8 after cutting will drive the cutting knife 6 to move upward. Then, the upward-moving hydraulic rod 8 drives the control rod 4 to move upward and rotate through the cutting knife 6. At this time, because of the drive of the cutting knife 6, the control rod 4 will rotate around the support 3 as the center point. When one end of the control rod 4 rises, the height of the other end will decrease. And a cutting knife 16 is installed on one side surface of the control rod 4. At this time, the cutting knife 16 whose height changes due to rotation will cut the long roll of conductive foam after cutting. The cutting of the long roll of conductive foam is achieved through the shearing force between the cutting knife 16 and the shear block 15. Embodiment 2

[0027] Based on the above Embodiment 1, please refer to Figure 5 , the conveying assembly includes a motor 9. A transmission shaft 10 is installed on one side surface of the motor 9. A track disk 11 is installed on the outer surface of the transmission shaft 10. A transmission track 17 is installed on the outer surface of the track disk 11. A pushing roller 12 is installed on the outer surface of the transmission shaft 10. A rubber shaft 13 is installed on the top surface of the workbench 1. A transmission disk 14 is installed on one side surface of the rubber shaft 13. The motor 9 is installed on the top surface of the workbench 1.

[0028] One end of the transmission shaft 10 is fixedly connected to the output end of the motor 9. The outer surface of the transmission shaft 10 is in movable rotational connection with the inner wall of the support 3. The inner wall of the transmission track 17 is in movable contact with the outer surface of the track disk 11. The inner wall of the transmission track 17 is in movable rotational connection with the outer surface of the rubber shaft 13.

[0029] When the cutting is completed, the hydraulic rod 8 will drive the cutting knife 6 to move upward and reset again, so as to realize the cutting of the conductive foam. And because the outer surface of the transmission shaft 10 is equipped with a crawler disc 11, and the outer surface of the crawler disc 11 is equipped with a transmission crawler 17. When the transmission shaft 10 is driven by the motor 9 to rotate, it will drive the transmission crawler 17 on its outer surface to rotate through the crawler disc 11. At the same time, the inner wall of the transmission crawler 17 is in contact with the outer surface of the transmission disc 14. Therefore, at this time, the transmission crawler 17 will drive the transmission disc 14 and the rubber shaft 13 installed on one side surface of it to rotate, and through the synchronous rotation of the rubber shaft 13 and the pushing roller 12, the precise output of the conductive foam is realized.

[0030] The working principle and usage process of the utility model: When the precision die-cutting device for conductive foam is needed, at this time, the long-roll-shaped conductive foam is placed in the transportation groove 2 opened on the top surface of the workbench 1, and the conductive foam is made to pass through between the workbench 1, the rubber shaft 13 and the pushing roller 12. When the conductive foam needs to be cut, at this time, the motor 9 is started. When the motor 9 is started, it will drive the transmission shaft 10 installed at its output end to rotate. And the transmission shaft 10 is fixedly connected with the pushing roller 12. Therefore, at this time, the rotating transmission shaft 10 will drive the pushing roller 12 to rotate, so that the rotating pushing roller 12 pushes the conductive foam in the transportation groove 2 to move on the inner wall of the transportation groove 2. When the pushing roller 12 pushes the conductive foam to move directly below the cutting knife 6, at this time, the hydraulic rod 8 will drive the cutting knife 6 to move downward, so that the downward moving cutting knife 6 cuts the conductive foam. When the cutting is completed, the hydraulic rod 8 will drive the cutting knife 6 to move upward and reset again, so as to realize the cutting of the conductive foam. And because the outer surface of the transmission shaft 10 is equipped with a crawler disc 11, and the outer surface of the crawler disc 11 is equipped with a transmission crawler 17. When the transmission shaft 10 is driven by the motor 9 to rotate, it will drive the transmission crawler 17 on its outer surface to rotate through the crawler disc 11. At the same time, the inner wall of the transmission crawler 17 is in contact with the outer surface of the transmission disc 14. Therefore, at this time, the transmission crawler 17 will drive the transmission disc 14 and the rubber shaft 13 installed on one side surface of it to rotate, and through the synchronous rotation of the rubber shaft 13 and the pushing roller 12, the precise output of the conductive foam is realized.

[0031] When cutting the conductive foam, the computer can simultaneously control the rotation speed of the motor 9 and the descending timing of the hydraulic rod 8. By controlling the two, precise cutting of the conductive foam can be achieved. When it is necessary to slice and divide the long roll of conductive foam after cutting, the computer can monitor the hydraulic rod 8. By controlling the cutting times of the conductive foam by the hydraulic rod 8, the upward movement of the hydraulic rod 8 is triggered. When the hydraulic rod 8 continuously moves downward to cut the conductive foam and reaches a certain number of cutting times for the long roll of conductive foam, the hydraulic rod 8 after cutting will drive the cutting knife 6 to move upward. At this time, the upward-moving hydraulic rod 8 drives the control rod 4 to move upward and rotate through the cutting knife 6. At this time, because of the drive of the cutting knife 6, the control rod 4 will rotate around the bracket 3 as the center point. When one end of the control rod 4 rises, the height of the other end will decrease. A cutting knife 16 is installed on one side surface of the control rod 4. At this time, the cutting knife 16 with a changing rotation height will cut the long roll of conductive foam after cutting. The cutting of the long roll of conductive foam is achieved through the shearing force between the cutting knife 16 and the shear block 15.
