[0038] Conductive foam possesses excellent electrostatic protection, corrosion resistance, and oxidation resistance, making it widely used in electronic products such as PDP TVs, LCD monitors, LCD TVs, mobile phones, laptops, MP3 players, communication cabinets, and medical instruments, as well as in military and aerospace fields. Conductive foam is available in various cross-sectional shapes, installation methods, UL ratings, and shielding effectiveness.
[0039] In related technologies, some conductive foam molding strips consist of multiple conductive foam raw materials attached parallel to a base film. To facilitate transportation and assembly, the molding strips need to be cut into sheets. The traditional method for cutting conductive foam molding strips is to cut vertically with a cutter and press down to slice the material. However, this processing method easily causes the sheets to be damaged and wrinkled, resulting in a low yield.
[0040] To address the technical deficiencies in related technologies, this invention provides a conductive foam cutting device, which includes a cutting device, a feeding device, a receiving device, and a cleaning device. The material shortage device includes a cutting component and a loading platform. The material strip is placed on the loading platform. The cutting component includes a disc cutter that rotates and cuts the material strip in a direction perpendicular to the material strip. The cleaning device can clean the impurities adhering to the disc cutter, enabling the disc cutter to cut a smoother end face and reducing burrs and debris on the cut sheet.
[0041] Reference Figure 1 and Figure 2 The conductive foam cutting equipment provided in this embodiment of the invention includes: a machine base 100; and a cutting device 200 disposed on the machine base 100. The cutting device 200 includes a cutting assembly 210 and a loading platform 220. The material strip can be placed on the loading platform 220. The loading platform 220 is provided with a first groove 221, which is perpendicular to the material strip. The cutting assembly 210 is provided with a disc cutter 2111, which can rotate to cut the material strip and can cut along the first groove. The trough 221 moves; the feeding device 300, set on the machine base 100, can convey the material belt to the loading platform 220; the receiving device 400, set on the machine base 100, can collect the cut sheet into the storage box 600; the cleaning device 500, set on the machine base 100, can spray cleaning agent onto the disc cutter 2111 and clean the impurities adhering to the disc cutter 2111 during the cutting process.
[0042] It should be noted that the feeding device 300 is located on the machine base 100, and the loading platform 220 is located in front of the feeding device 300. The feeding device 300 transports the material strip to the loading platform 220, where the material strip is cut. A cutting assembly 210 is located in front of the loading platform 220, and the cutting assembly 210 is equipped with a disc cutter 2111. The cutting assembly 210 can move left and right in the horizontal direction. The cutting of the material strip is achieved by the rotation of the disc cutter 2111 and its horizontal movement on the material strip. Specifically, the disc cutter 2111 can be engaged in the first groove 221 and move along the length of the first groove 221. A receiving device 400 is located to the left of the loading platform 220, and a material box 600 is located to the right of the loading platform 220. The receiving device 400 transfers the cut sheet material into the material box 600. The cleaning device 500 is located on the left side of the cutting assembly 210. The cleaning device 500 is filled with a dry release agent. Since the material strip is made of plastic, adhesive debris will stick to the blade of the disc cutter 2111 during the cutting process, which will affect the cutting quality of the disc cutter 2111. Therefore, the cleaning device 500 can effectively clean the adhesive debris on the disc cutter 2111.
[0043] Reference Figure 3 and Figure 4 The cutting assembly 210 also includes a base 212, a movable support 213, and a cutting machine 211. The movable support 213 is slidably disposed on the base 212, and the movement direction of the movable support 213 is parallel to the first groove 221. The cutting machine 211 is disposed on the movable support 213, and a disc cutter 2111 is disposed on the cutting machine 211. The disc cutter 2111 is made of tungsten steel and its surface is coated with Teflon material.
[0044] It should be noted that a screw 2121 is provided inside the base 212, and a first motor 2122 is provided at the end of the base 212, which drives the screw 2121 to rotate. A slider (not shown in the figure) is provided at the bottom of the movable bracket 213, and the slider is set on the screw 2121. When the screw 2121 rotates, the slider can move on the screw 2121. The base 212 is also provided with a guide rail ridge 2123, and the movable bracket 213 is provided with a guide rail groove 2124. The guide rail groove 2124 is slidably connected to the guide rail ridge 2123, and the movable bracket 213 can slide on the guide rail. The base 212 is also equipped with a dust cover 2125, which is used to protect the screw 2121 and the guide rail from dust. Specifically, the dust cover 2125 is an accordion-style dust cover 2125. One end of the accordion-style dust cover 2125 is connected to the movable bracket 213, and the other end is connected to the base 212. The movable bracket 213 is equipped with accordion-style dust covers 2125 on both sides in the direction of the guide rail.
[0045] It should be noted that a cutting machine 211 is mounted on the movable support 213, and the cutting machine 211 is equipped with a second motor 230. A disc cutter 2111 is also mounted on the cutting machine 211, and the second motor 230 drives the disc cutter 2111 to rotate. The cutting machine 211 is equipped with a protective cover 2112, which covers the disc cutter 2111, with a portion of the disc cutter 2111 protruding downwards from the protective cover 2112.
[0046] It should be noted that the base 212 is equipped with a cable carrier 2126, which is used to secure the cable so that it can follow the movement of the moving bracket 213. The cable carrier 2126 is made of reinforced nylon, which has high tensile load capacity, good toughness, high elasticity, wear resistance, flame retardancy, and stability at high and low temperatures.
[0047] Reference Figure 5 and Figure 6 The loading platform 220 also has multiple second grooves 222 arranged side by side, the second grooves 222 being perpendicular to the first groove 221. The material strip includes a base film and multiple conductive foam strips arranged side by side. The base film covers the loading platform 220, and the conductive foam strips face the machine base 100 and can be inserted into the second grooves 222. A vacuum adsorption device (not shown in the figure) is provided on the loading platform 220 near the first groove 221. The vacuum adsorption device can adsorb the base film and make the material strip adhere tightly to the loading platform 220.
[0048] It should be noted that when the material strip is placed on the carrier platform 220, the conductive foam faces downwards, that is, the bottom film is located above the conductive foam. The bottom film is covered by the second groove 222, and the conductive foam is inserted into the second groove 222 and limited by the second groove 222, which reduces the left and right swaying of the material strip during the cutting process, makes the cut end face flatter, and reduces burrs.
[0049] It should be noted that the first groove 221 is provided in one strip, and the first groove 221 is located near the end of the loading platform 220. Specifically, the first groove 221 connects one side of the loading platform 220 with the opposite side. The second groove 222 is provided perpendicular to the first groove 221, and multiple second grooves 222 are provided. The second groove 222 has an abutment part near the loading platform 220. When the conductive foam abuts against the abutment part of the loading platform 220, the conveyor belt stops transporting. The loading platform 220 is provided with a pressure plate 223, which abuts against the bottom film of the conveyor belt.
[0050] It should be noted that the loading platform 220 is provided with multiple vacuum adsorption holes 240 near the end, and a vacuum adsorption device is provided at the bottom of the loading platform 220. The vacuum adsorption device is a small vacuum machine. The small vacuum machine is connected to the vacuum adsorption holes 240 and can form a negative pressure at the vacuum adsorption holes 240, so that the material strip is tightly attached to the loading platform 220, preventing the material strip from vibrating during the cutting process and preventing the sheet from falling off.
[0051] Reference Figure 7 The feeding device 300 includes a conveyor table 310 and a drive roller assembly 320. The conveyor table 310 can convey the material belt to the loading platform 220. The drive roller assembly 320 includes a first mounting frame 321, an active guide roller 322, and a pressing guide roller 323. The active guide roller 322 and the pressing guide roller 323 are disposed on the first mounting frame 321. The active guide roller 322 and the pressing guide roller 323 squeeze and drive the material belt. The active guide roller 322 has extrusion sections 3221 at both ends. The extrusion sections 3221 and the middle part of the active guide roller 322 have a height difference, and the extrusion sections 3221 are higher than the middle part. The pressing guide roller 323 is provided with rollers. The material belt includes a base film and conductive foam disposed on the base film. The extrusion sections 3221 cooperate with the rollers to squeeze and drive the base film, and the conductive foam passes through the middle part.
[0052] It should be noted that the pressure guide roller 323 is located above the active guide roller 322. The pressure guide roller 323 is a double-shoulder roller, meaning it has two rollers. The bottom film of the material strip is squeezed by the rollers and the active guide roller 322. The active guide roller 322 is driven by a third motor 330. The first mounting bracket 321 is also equipped with a second cylinder 800, which can drive the pressure guide roller 323 to move up and down. Locking devices are provided at both ends of the pressure guide roller 323 to fix its position.
[0053] Reference Figure 8 The receiving device 400 includes a robotic arm 410 and an adsorption component 420. The adsorption component 420 is mounted on the robotic arm 410, which drives the adsorption component 420 to move. The adsorption component 420 can adsorb sheet material. It should be noted that the adsorption component 420 includes a connector 421 and two suction cups 422, which are symmetrically arranged on the connector 421 and connected to the robotic arm 410. After the suction cups 422 adsorb the sheet material, the robotic arm 410 controls the suction cups 422 to move from the loading platform 220 to the material box 600.
[0054] Reference Figure 9 The cleaning device 500 includes a second mounting bracket 510, a high-pressure storage tank 520, and a first cylinder 700. The second mounting bracket 510 is mounted on the machine base 100, and the high-pressure storage tank 520 and the first cylinder 700 are mounted on the second mounting bracket 510. The high-pressure storage tank 520 is equipped with a valve 521, and the first cylinder 700 can push and open the valve 521. The high-pressure storage tank 520 is also equipped with a nozzle 522, which is connected to the valve 521. The nozzle 522 is a universal nozzle, and the universal nozzle can adjust the spray angle.
[0055] It should be noted that the high-pressure storage tank 520 contains a dry mold release agent, which can release plastic materials from the mold. That is, when the dry mold release agent is sprayed onto the disc cutter 2111, the adhesive on the disc cutter 2111 can be removed from the disc cutter 2111, thus achieving the purpose of cleaning the impurities on the disc cutter 2111.
[0056] It should be noted that valve 521 is a push-button valve 521, which is controlled to open or close by the first cylinder 700. In some other embodiments, valve 521 can be other types of valves 521, which will not be described in detail here. The first cylinder 700 is equipped with a detector, which can detect the position of the push rod of the first cylinder 700. The detector can be a contact switch.
[0057] 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 knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
