Description

Technical Field

[0001] This utility model relates to the field of conductive foam processing equipment, and in particular to a high-precision coating device for conductive foam. Background Technology

[0002] Conductive foam is a special foam material with conductive properties. It is usually composed of a foam substrate and a conductive layer. The foam substrate provides good elasticity and cushioning performance, while the conductive layer gives it good surface conductivity. It can be easily fixed to the device that needs to be shielded with adhesive tape. The high-precision coating device is a device that can accurately control the thickness and uniformity of the coating layer, so that the conductive foam can ensure that its conductivity, corrosion resistance and antistatic ability are not affected during the processing.

[0003] During the use of the covering device, in order to ensure that the conductive foam does not shift or shake during movement, a limiting device is usually installed at the top of the covering device. Most of the current limiting devices are bolt-type clamps, which move the pressure bar towards the surface of the conductive foam by lifting the pull rod, thereby limiting the conductive foam. However, this limiting method usually results in excessive pressure on the surface of the conductive foam at one end of the pressure bar, which can damage the surface of the conductive foam during the pulling process, thus affecting the product quality of the conductive foam. At the same time, the position of the pressure bar is not adjustable, which reduces the practicality of the equipment.

[0004] Therefore, it is necessary to provide a new high-precision coating device for conductive foam to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-precision coating device for conductive foam.

[0006] The conductive foam high-precision coating device provided by this utility model includes a base for coating conductive foam, and the top of the base is provided with a plurality of positioning structures for limiting the conductive foam.

[0007] The positioning structure includes a base plate, a movable frame, multiple moving components, and multiple extrusion rollers. The bottom of the base plate is fixedly connected to the top of the base. The top of the base plate has a groove for conductive foam to pass through. A limiting plate is provided on the top of the base plate. The movable frame is connected to the inner side of the limiting plate by multiple springs. The bottom of the movable frame has multiple moving slots for the moving components to move, and a limiting post is fixedly provided inside the moving slot. The top of the moving component is sleeved on the outside of the limiting post. The multiple extrusion rollers are located inside the multiple moving components, and the extrusion rollers are rotatably connected to the moving components.

[0008] Preferably, the movable component includes a mounting plate and a movable block. The bottom of the movable block is fixedly connected to the top of the mounting plate. The movable block is sleeved on the outside of the limiting post. The bottom of the mounting plate has a mounting groove. The extrusion wheel is located inside the mounting groove. The extrusion wheel is rotatably connected to the inside of the mounting groove.

[0009] Preferably, the outer side of the limiting post is provided with a plurality of protrusions for increasing friction.

[0010] Preferably, the movable frame is provided with a pull rod at the top.

[0011] Preferably, the top of the base is provided with multiple cutting devices, each including a cylinder, a cutting blade, and a fixing plate. The bottom of the fixing plate is fixedly connected to the top of the base, and the surface of the fixing plate is provided with a through groove for conductive foam to pass through. One end of the cylinder is fixedly connected to the top of the fixing plate, and the output end of the cylinder passes through the top of the fixing plate and extends into the through groove. The output end of the cylinder is fixedly connected to the top of the cutting blade.

[0012] Preferably, the through groove of the fixing plate is provided with a fixing rod, and the top of the fixing rod is provided with a slot that matches the bottom of the cutting blade.

[0013] Preferably, the top of the base is also provided with multiple pressing devices for squeezing the conductive foam.

[0014] Compared with related technologies, the high-precision conductive foam coating device provided by this utility model has the following advantages:

[0015] 1. Pull the movable frame to compress the spring between the movable frame and the limiting plate, allowing the conductive foam to pass through the groove on the top of the base plate. Release the movable frame, and under the elastic action of the spring, push the movable frame and the extrusion wheel towards the surface of the conductive foam. The extrusion wheel limits the conductive foam, and during the pulling of the conductive foam, the extrusion wheel rotates inside the moving component due to the contact between the conductive foam and the extrusion wheel, thereby reducing the friction between the extrusion wheel and the conductive foam. This can reduce the wear on the surface of the conductive foam to a certain extent and improve product quality.

[0016] 2. Pull the moving component to move it on the surface of the limiting column. The moving component drives the extrusion roller to move in the groove opened on the top of the base plate, thereby adjusting the position of the extrusion roller so that it can better extrude and limit the conductive foam surface passing through the groove, which improves the practicality of the equipment to a certain extent.

[0027] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 ,in, Figure 1 A schematic diagram of the overall structure of the high-precision conductive foam coating device provided by this utility model; Figure 2 A schematic diagram of the overall structure of the positioning structure provided by this utility model; Figure 3 A cross-sectional structural diagram of the positioning structure provided by this utility model; Figure 4 A schematic diagram of the disassembled structure of the positioning structure provided by this utility model; Figure 5 A partial structural diagram of the positioning structure provided by this utility model; Figure 6 A cross-sectional structural diagram of the movable frame provided by this utility model; Figure 7 A cross-sectional structural diagram of the moving component and the extrusion wheel provided by this utility model; Figure 8 A schematic diagram of the overall structure of the cutting equipment provided by this utility model; Figure 9 A cross-sectional structural diagram of the cutting equipment provided by this utility model.

[0029] In the specific implementation process, such as Figures 1-9 As shown, a high-precision coating device for conductive foam is characterized by comprising a base 1 for coating conductive foam, a plurality of positioning structures 2 for limiting the conductive foam on the top of the base 1, the positioning structure 2 comprising a base plate 3, a movable frame 4, a plurality of moving components 5 and a plurality of extrusion wheels 6, the bottom of the base plate 3 being fixedly connected to the top of the base 1, the top of the base plate 3 having a groove 7 for the conductive foam to pass through, the top of the base plate 3 having a limiting plate 8, the movable frame 4 being connected to the inner side of the limiting plate 8 by a plurality of springs 9, the bottom of the movable frame 4 having a plurality of moving slots 10 for the moving components 5 to move, and a limiting post 11 being fixedly provided inside the moving slots 10, the top of the moving components 5 being sleeved on the outer side of the limiting post 11, the plurality of extrusion wheels 6 being located inside the plurality of moving components 5 respectively, and the extrusion wheels 6 being rotatably connected to the moving components 5. Due to the friction between the conductive foam and the extrusion wheels 6, when the conductive foam moves inside the groove 7, it will drive the extrusion wheels 6 to rotate, thereby reducing the friction between the conductive foam and the extrusion wheels 6.

[0030] The movable component 5 includes a mounting plate 12 and a movable block 13. The bottom of the movable block 13 is fixedly connected to the top of the mounting plate 12. The movable block 13 is sleeved on the outside of the limiting post 11. The bottom of the mounting plate 12 has a mounting groove 14. The extrusion wheel 6 is located inside the mounting groove 14 and is rotatably connected to the inside of the mounting groove 14. The outside of the limiting post 11 has multiple protrusions 15 to increase friction. The top of the movable frame 4 has a pull rod 16. The top of the base 1 has multiple cutting devices 17. The cutting device 17 includes a cylinder 18, a cutting blade 19, and a fixing plate 20. The bottom of the fixing plate 20 is fixedly connected to the top of the base 1. The surface of the fixing plate 20 has a surface for conductive foam to pass through. The through groove 21 is formed by the cylinder 18, one end of which is fixedly connected to the top of the fixed plate 20. The output end of the cylinder 18 passes through the top of the fixed plate 20 and extends into the through groove 21. The output end of the cylinder 18 is fixedly connected to the top of the cutting blade 19. The conductive foam in the groove 7 is passed through the pressing device 24 and the through groove 21 opened in the fixed plate 20 in sequence, and the bottom of the conductive foam contacts the top of the fixed rod 22. By pushing the cylinder 18, the cutting blade 19 moves towards the top of the conductive foam, thereby cutting the conductive foam. Because the top of the fixed rod 22 is provided with a slot 23 that matches the cutting blade 19, the cutting blade 19 can be more stable during the cutting process and the cutting error can be reduced.

[0031] The through groove 21 of the fixing plate 20 is provided with a fixing rod 22, and the top of the fixing rod 22 is provided with a slot 23 that matches the bottom of the cutting blade 19. The top of the base 1 is also provided with multiple pressing devices 24 for squeezing the conductive foam.

[0032] The working principle provided by this utility model is as follows:

[0033] When the extrusion wheel 6 is needed to limit the conductive foam, pull the lever 16 upwards. The lever 16 drives the movable frame 4 to move, thereby compressing the spring 9 between the movable frame 4 and the limiting plate 8. This allows the conductive foam to pass through the groove 7 at the top of the base plate 3. At the same time, the movable frame 4 is released. Under the elastic action of the spring 9, the movable frame 4 is pushed towards the surface of the conductive foam, so that the surface of the extrusion wheel 6 comes into contact with the surface of the conductive foam. Under the push of the spring 9, the extrusion wheel 6 limits the conductive foam. During the process of pulling the conductive foam, there is friction between the conductive foam and the extrusion wheel 6. Since the extrusion wheel 6 is rotatably connected to the inner side of the mounting groove 14, the extrusion wheel 6 will rotate as the conductive foam moves inside the groove 7, thereby reducing the friction between the conductive foam and the extrusion wheel 6.

[0034] When the position of the extrusion wheel 6 needs to be adjusted, the moving block 13 is pulled to move on the surface of the limiting post 11. The moving block 13 drives the mounting plate 12 to move, thereby adjusting the extrusion wheel 6 set in the mounting plate 12. Since the moving block 13 matches the moving groove 10 opened at the bottom of the movable frame 4, the moving block 13 can be restricted to a certain extent to prevent the moving block 13 from shaking or moving. Since the limiting post 11 has multiple protrusions 15 on the outside, the contact area between the limiting post 11 and the moving block 13 can be increased, thereby making the moving block 13 more stable on the surface of the limiting post 11.

[0035] The conductive foam in the groove 7 is passed through the pressing device 24 and the through slot 21 opened in the fixing plate 20 in sequence, and the bottom of the conductive foam is brought into contact with the top of the fixing rod 22. The cutting blade 19 is moved towards the top of the conductive foam by the push of the cylinder 18, thereby cutting the conductive foam. Because the top of the fixing rod 22 has a slot 23 that matches the cutting blade 19, the cutting blade 19 can be more stable during the cutting process and the cutting error can be reduced.
