Description

Technical Field

[0001] The utility model relates to the technical field of conductive foam production, in particular to a conductive foam heating fixture with high heating efficiency. Background Art

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed to the device to be shielded with adhesive tape.

[0003] In the production process of conductive foam, the conductive cloth needs to be bonded to the foam. Usually, conductive glue is applied between the foam and the conductive cloth, and then the foam and the conductive cloth are squeezed to bond them together. If only extrusion bonding is used, the foam and the conductive cloth are easily separated. Furthermore, conductive glue with hot melt properties is used for bonding, and then the conductive foam after extrusion bonding is heated to enhance the bonding effect of the conductive glue.

[0004] A search revealed a Chinese patent application for a conductive foam heating jig with high heating efficiency (authorization publication number CN218227923U). The jig comprises a placement plate for placing conductive foam and a heating device disposed on the bottom surface of the placement plate for heating the conductive foam. The heating device comprises a heating plate and at least one heating block disposed on the top surface of the heating plate. The placement plate is provided with a heating port for the heating block to pass through and directly contact the conductive foam. The bottom surface of the placement plate contacts the top surface of the heating plate, and at least one sink is disposed in the area where the bottom surface of the placement plate contacts the top surface of the heating plate. When the conductive foam is placed on top of the placement plate, the heating port is located on the left and right sides of the conductive foam. Each sidewall on the left and right sides of the conductive foam contacts a heating block. This patented technology can improve the heating efficiency of the conductive foam by the heating device, thereby saving energy and working time.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that in the above solution, the heating plate is fixed to the bottom of the placement plate, and the heating block only contacts the two ends of the conductive foam and heats the conductive foam from both ends. There is no way to heat the conductive foam from the bottom, and the one-sided heating method reduces the heating efficiency. When fixing the heating plate, multiple screws need to be tightened, which delays a lot of production time. Utility Model Content

[0012] By adopting the above technical solution, the sealing groove and the sealing frame are used in conjunction with each other, which can reduce the escape of heat from the gap between the first movable frame and the second movable frame, thereby being able to retain most of the heat around the conductive foam.

[0013] As a preferred embodiment, a heating component is provided inside the first movable frame and the second movable frame, and the heating component includes a heat insulation box fixedly connected to the inside of the first movable frame and the second movable frame, and a heating plate is fixedly installed inside the heat insulation box, and resistance heating wires are fixedly installed at equal distances inside the heating plate.

[0017] As a preferred embodiment, two of the heat insulation box and heating plates are provided, and the adjacent sides of the first movable frame and the second movable frame are pressed against each other.

[0018] By adopting the above technical solution, the escape of hot air can be avoided by the tight state.

[0019] As a preferred embodiment, the top end of the screw rod extends to the outside of the fixed bracket and is fixedly connected to the handle.

[0020] By adopting the above technical solution and using the turning handle, the screw rod can be rotated easily.

[0021] As a preferred embodiment, a controller is fixedly installed on the outer side of the heating jig table, and the resistance heating wire is electrically connected to the controller.

[0022] By adopting the above technical solution and setting the controller, the resistance heating wire can be controlled to start and stop.

When the first movable frame and the second movable frame are in a fitted state, the sealing component can be fitted more tightly, which can prevent the escape of hot air during the heating process, thereby improving the heating efficiency of the conductive foam.

[0025] 2.

During the loading process of the conductive foam, it is only necessary to reverse the screw without tightening multiple screws. The use method is more convenient, thereby improving the production efficiency of the conductive foam. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1The lifting assembly includes a screw 10 rotatably connected to the inside of one of the fixed brackets 3, and the inside of the other fixed bracket 3 is fixedly connected to a fixed rod 8. The outer side of the screw 10 is threadedly connected to a threaded block 11, and the outer side of the fixed rod 8 is slidably connected to a slider 9. Through the rotation of the screw 10, the threaded block 11 can be driven to slide in one of the fixed brackets 3. The setting of the fixed rod 8 and the slider 9 can improve the stability of the first movable frame 5 during movement and reduce its shaking phenomenon, thereby driving the entire first movable frame 5 to move downward and cooperate with the second movable frame 6. During the loading process of the conductive foam, it is only necessary to reverse the screw 10, and there is no need to tighten multiple screws. The use method is more convenient, which can improve the production efficiency of the conductive foam.

[0033] Reference Figure 2 The sealing assembly includes a sealing frame 13 fixedly connected to the top of the second movable frame 6. A sealing groove 12 is opened inside the first movable frame 5 to cooperate with the sealing frame 13. The sealing groove 12 is engaged with the sealing frame 13. Through the cooperation of the sealing groove 12 and the sealing frame 13, the heat can be reduced from escaping from the gap between the first movable frame 5 and the second movable frame 6, and most of the heat can be retained around the conductive foam, thereby improving the heating efficiency of the conductive foam.

[0034] Reference Figure 3 A heating component is provided inside the first movable frame 5 and the second movable frame 6. The heating component includes a heat-insulating box 7 fixedly connected to the first movable frame 5 and the second movable frame 6. A heating plate 14 is fixedly installed inside the heat-insulating box 7. Resistance heating wires 15 are fixedly installed at equal intervals inside the heating plate 14. By turning on the resistance heating wires 15, the resistance heating wires 15 can generate heat, and thereby heat both sides of the conductive foam. The heat-insulating box 7 can block the heat generated by the heating plate 14, thereby reducing the impact of high temperature on the second movable frame 6.

[0035] Reference Figure 3 The threaded block 11 and the slider 9 are fixedly connected to both sides of the first movable frame 5 respectively. There are two heat insulation boxes 7 and heating plates 14. The first movable frame 5 and the second movable frame 6 are close to each other on one side. The tight state can prevent hot air from escaping.

[0036] Reference Figure 2 The top end of the screw rod 10 extends to the outside of the fixed bracket 3 and is fixedly connected to the turning handle 4. The turning handle 4 is used to facilitate the rotation of the screw rod 10.

[0037] Reference Figure 1 A controller 2 is fixedly installed on the outside of the heating jig table 1, and the resistance heating wire 15 is electrically connected to the controller 2. Through the setting of the controller 2, the resistance heating wire 15 can be controlled to start and stop.

[0038] Working principle: First, when heating the conductive foam, the conductive foam can be placed on the heating plate 14 in the second movable frame 6. Then, the handle 4 is turned. Through the rotation of the screw 10, the threaded block 11 can be driven to slide in one of the fixed brackets 3, thereby driving the entire first movable frame 5 to move downward and cooperate with the second movable frame 6. During the loading process of the conductive foam, it is only necessary to reverse the screw 10, and there is no need to tighten multiple screws, which is more convenient to use. The first movable frame 5 and the second movable frame 6 are clamped on both sides, which can increase the contact area between the conductive foam and the heating plate 14, and the heating plate 14 can fully contact the side of the conductive foam, thereby improving the heating efficiency of the conductive foam.

[0039] When the first movable frame 5 and the second movable frame 6 are in a fitted state, the sealing groove 12 and the sealing frame 13 will fit more tightly, which can reduce the escape of heat from the gap between the first movable frame 5 and the second movable frame 6, and thus most of the heat can be retained around the conductive foam, thereby improving the heating efficiency of the conductive foam. Finally, the resistance heating wire 15 can be turned on by the controller 2, so that the heating plate 14 can generate heat, and thereby heat both sides of the conductive foam, and the heat insulation box 7 can block the heat generated by the heating plate 14, which can reduce the impact of high temperature on the second movable frame 6.
