Description

Technical Field

[0001] The invention relates to the technical field of digital television antenna processing, in particular to a glue brushing component for preparing a television antenna conductive circuit. Background Art

[0002] There are two conventional processes for making conductive lines of thin-film TV antennas on the market. One is to use a screen printer to print the conductive lines on the substrate with conductive silver paste, and then solidify them in a high-temperature oven. The disadvantage of this method is that the impedance of the conductive line is large. If the impedance is to be small, the silver content of the conductive silver paste must be increased, which will inevitably lead to an increase in cost.

[0003] Another method is to use adhesive conductive aluminum foil or copper foil. The adhesive aluminum foil or copper foil with release paper is first cut into the shape of the conductive circuit by a die-cutting machine. Then the excess aluminum foil or copper foil is manually removed. The circuit part is left, and then the aluminum foil or copper foil circuit is attached to the substrate by transfer. The disadvantage of this method is that during the waste discharge process of the aluminum foil or copper foil, because the aluminum foil is very fragile, it is easy to tear the circuit, causing the aluminum foil circuit to be scrapped. At the same time, when transferring the aluminum foil or copper foil circuit, it is also easy to cause damage to the aluminum foil or copper foil circuit. The aluminum foil or copper foil circuit needs to be transferred separately, and the production efficiency is low, resulting in high product costs. Summary of the invention

[0045] Step 4: After the machine discharges waste, the final antenna conductive circuit 3 is obtained.

[0046] The working principle and beneficial effects of the above scheme:

[0047] The present invention directly attaches the Mylar conductive metal film 2 to the substrate 1 by glue, without the need for transfer, thus saving labor costs. At the same time, because the Mylar conductive metal film 2 has good toughness, it is not easy to be torn. It can be discharged by a machine. The product defect rate is greatly reduced and the production efficiency is improved. As a result, the film antenna made by the present invention has low cost. It does not require high-temperature oven curing, and consumes less electricity in production. It is energy-saving and environmentally friendly.

[0048] Example 2

[0049] See also Figure 3-5On the basis of Example 1, in step 1, the Mylar metal film 2 or the substrate 1 is glued by a glue brushing assembly;

[0050] The glue brushing assembly includes a rubber roller 10, which is rotatably connected to a frame 7. A threaded connection ring 6 and a slip ring 8 are provided on the frame 7. A screw rod 5 is threadedly connected to the threaded connection ring 6. A slide rod 9 is slidably connected to the slip ring 8. One end of the screw rod 5 is fixedly connected to a drive head 4, and the drive head 4 is connected to a drive motor.

[0051] Preferably, the screw rod 5 and the slide rod 9 are arranged in parallel.

[0052] Preferably, a rotating shaft 11 is rotatably connected to the frame 7, and the rubber roller 10 is fixedly connected to the rotating shaft 11;

[0053] The rotating shaft 11 is fixedly connected with a half gear 12, and the teeth of the half gears 12 at both ends of the rotating shaft 11 are in opposite directions;

[0054] The half gear 12 of the rotating shaft 11 is meshed with the rack 13, and the rack 13 is fixedly connected to the connecting plate 14. One end of a limited telescopic rod 19 is fixedly connected to the connecting plate 14, and the other end of the limited telescopic rod 19 is fixedly connected to the frame 7. A first elastic member 18 is sleeved on the limited telescopic rod 19, and two ends of the first elastic member 18 are respectively abutted against the connecting plate 14 and the frame 7;

[0055] A fixing plate 15 is slidably connected to the connecting plate 14 , and the fixing plate 15 is fixedly connected to the frame 7 .

[0056] Preferably, a glue storage bin 16 is fixedly connected to the connecting plate 14 , the glue storage bin 16 is located between the connecting plate 14 and the rubber roller 10 , and a hole for discharging glue is provided on a side of the glue storage bin 16 facing the rubber roller 10 .

[0057] Preferably, the side of the glue storage bin 16 away from the glue roller 10 is made of a flexible material.

[0058] The working principle and beneficial effects of the above scheme:

[0059] When applying glue to the Mylar metal film 2 or the substrate 1, the driving motor connected to the driving head 4 is started to drive the screw 5, and the driving motor changes direction when the threaded connection ring 6 reaches both ends of the screw 5, so that the threaded connection ring 6 drives the frame 7 to move repeatedly in the direction of the screw 5, so that the rubber roller 10 can apply glue multiple times, ensuring the stability of applying glue, avoiding the phenomenon that the substrate 1 and the Mylar metal film 2 are not firmly bonded, and effectively improving the reliability of the conductive circuit 3;

[0060] The screw rod 5 and the slide rod 9 are arranged in parallel to ensure the stability of the frame 7 moving in the direction of the screw rod 5, and further ensure the reliability of the conductive circuit 3;

[0061] During the process of applying glue to the rubber roller 10, the rotation of the rubber roller 10 drives the half gear 12 to rotate, and the rotation of the half gear 12 causes the rack 13 to drive the flexible shell of the glue storage bin 16 away from the side of the rubber roller 10 to move, and the glue in the glue storage bin 16 is squeezed onto the rubber roller 10, and then the half gear 12 is separated from the rack 13, and the flexible shell of the glue storage bin 16 away from the side of the rubber roller 10 is restored to its original state under the action of the first elastic member 18, and then the above actions are repeated to complete the automatic export of the rubber material, thereby improving the work efficiency;

[0062] Since the teeth of the half gears 12 at both ends of the rotating shaft 11 are in opposite directions, the rubber material can be automatically discharged when the rubber roller 10 rotates clockwise or counterclockwise.

[0064] See also Figure 6-8 On the basis of Embodiment 1-2, the rubber roller 10 is provided with a rubber outlet 21, the rubber roller 10 is a tubular structure, and sealing baffles 22 are fixedly connected at both ends of the rubber roller 10;

[0065] One end of the rotating shaft 11 is a hollow structure, and the hollow end of the rotating shaft 11 is connected to the rubber inlet pipe 20. The rotating shaft 11 is located in the rubber roller 10 and is close to the sealing baffle 22. A hole connecting the rubber inlet pipe 20 and the inside of the rubber roller 10 is provided;

[0066] The portion of the rotating shaft 11 located inside the rubber roller 10 is rotatably connected to the second stirring rod 23 and the first stirring rod 30 .

[0067] Preferably, a cavity 28 and a fixed stopper 29 are provided in the side wall of the rubber roller 10, and the cavity 28 and the fixed stopper 29 are arranged adjacent to each other. A second elastic member 27 is provided in the cavity 28, one end of the second elastic member 27 is fixedly connected to the fixed stopper 29, and the other end of the second elastic member 27 is fixedly connected to a stopper 26, and an electromagnet 25 is fixedly connected to the stopper 26, and two adjacent groups of stoppers 26 are both located in the rubber outlet 21, and the stoppers 26 are slidably connected to the side wall of the rubber roller 10;

[0068] An opening and closing section 24 is formed between two adjacent groups of stoppers 26 .

[0069] Preferably, a heating wire 31 is provided in the first stirring rod 30;

[0070] A third elastic member 32 is provided in the second stirring rod 23 , one end of the third elastic member 32 is fixedly connected to one end of the inner wall of the second stirring rod 23 close to the rotating shaft 11 , and the other end of the third elastic member 32 is fixedly connected to a sliding contact 33 , and the sliding contact 33 is slidably connected to a resistance wire 34 , and the resistance wire 34 is fixedly connected to the inner wall of the second stirring rod 23 .

[0071] Preferably, the resistance wire 34 is electrically connected to the electromagnet 25 .

[0072] The working principle and beneficial effects of the above scheme:

[0073] When applying glue to the Mylar metal film 2 or the substrate 1, the glue of component A is discharged from the glue storage bin 16, and the glue of component B is discharged from the glue roller 10, and the mixing is completed on the surface of the glue roller 10. The mixing timing of the two components of glue can be controlled by two sets of glue discharge structures, further ensuring the stability of the bonding between the substrate 1 and the Mylar metal film 2 and the reliability of the conductive circuit 3;

[0074] The B component glue enters the rubber roller 10 from the glue adding port 17. After the glue brushing action is started, the second stirring rod 23 and the first stirring rod 30 rotate around the rotating shaft 11 to ensure the uniformity of the B component glue in the rubber roller 10. At the same time, the heating wire 31 in the first stirring rod 30 is started to heat it to ensure that it is in a molten state. As the temperature rises, the viscosity of the B component glue decreases, the rotation speed of the second stirring rod 23 increases, and the sliding contact 33 moves outward under the action of centrifugal force. The effective resistance on the resistance wire 34 decreases, and the current of the electromagnet 25 connected thereto increases. The repulsive force of the two adjacent groups of electromagnets 25 is enhanced, overcoming the elastic force of the second elastic member 27. The two adjacent groups of stoppers 26 are separated and discharged from the glue outlet 21 to mix with the A component glue on the surface of the rubber roller 10, and then the glue brushing operation is performed;

[0075] By automatically adjusting and exporting the glue in the rubber roller 10, the efficiency of brushing glue is effectively improved.
