Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, specifically to a fixture for bonding high-resilience conductive foam. Background Technology

[0002] Conductive foam is a shielding material with good surface conductivity, and it is widely used in electronic products such as monitors, LCD TVs, mobile phones, laptops, communication cabinets and medical instruments. When conductive foam is bonded to the base film, a bonding fixture is required.

[0003] Existing technologies, such as the utility model disclosed in patent publication number CN222004439U, disclose a conductive foam bonding fixture, including a base. The base is square in shape, and an adjustment box is provided on the top of the base via an adjustment mechanism. A pressure roller is rotatably mounted inside the adjustment box. The adjustment mechanism, including knobs, screws, and screw holes, allows for the raising and lowering of the adjustment plate and adjustment box. This causes the adjustment box to lift the protrusion and separate it from the slot, creating a gap between one end of the adjustment box and the base. This facilitates the placement of the base film and conductive foam strips into the first and second limiting grooves, thus guiding and limiting the base film and conductive foam. The pressure roller compresses the base film and conductive foam strips, facilitating bonding. The adjustment mechanism also allows for the raising and lowering of the height of the second and first limiting grooves, changing the distance between the top of the second limiting groove and the base. This facilitates bonding conductive foam of different thicknesses and offers high practicality.

[0004] The device has a pressure roller that can be adapted to conductive foam of different thicknesses. However, when it is used to press and bond high-resilience conductive foam, the bonding effect is poor and the high-resilience conductive foam cannot be pressed tightly onto the base film.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a high-resilience conductive foam bonding fixture that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a high-resilience conductive foam bonding fixture, comprising: a base, an adjustment frame, a pressing roller, and an adjustment mechanism for adjusting the position of the pressing roller;

[0008] The adjustment mechanism includes: a motor, the output shaft of which is fixedly connected to a threaded rod, a lifting plate threadedly mounted on the threaded rod, a lifting block fixedly connected to the lifting plate, a roller shaft rotatably mounted on the lifting block, and the pressure roller fixedly mounted on the roller shaft.

[0009] Furthermore, the adjustment frame is provided with symmetrical mounting slots on both sides, and the lifting block is slidably installed in the mounting slots.

[0010] Furthermore, connecting plates are fixedly connected to both sides of the lifting block, and lifting rods are fixedly connected to the connecting plates.

[0011] Furthermore, a support plate is fixedly connected to the bottom of the adjustment frame, and a support spring is fixedly installed between the support plate and the top of the inner wall of the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a high resilience conductive foam bonding fixture, which drives the threaded rod to rotate by a motor, so that the lifting plate can drive the lifting block to rise and fall, the lifting block drives the roller shaft to fall, and the roller shaft drives the pressing roller to fall, so that the pressing roller can press the high resilience conductive foam tightly.

[0021] like Figures 1 to 4 As shown, this utility model discloses a high-resilience conductive foam bonding fixture, comprising: a base 1, an adjustment frame 2, a pressing roller 14, and an adjustment mechanism for adjusting the position of the pressing roller 14.

[0022] The base 1 is provided with a sliding groove 19, in which an adjustment frame 2 is slidably installed. The bottom of both ends of the adjustment frame 2 is provided with a second limiting groove 5, and the top of the second limiting groove 5 is provided with a first limiting groove 4 evenly distributed. The second limiting groove 5 is used to limit the bottom film, and the first limiting groove 4 is used to position the slit conductive foam. The bottom of one side of the adjustment frame 2 is provided with a feeding groove 9, and the base 1 is provided with a slot 20 aligned with both ends of the feeding groove 9. The two sides of the adjustment frame 2 are symmetrically provided with mounting grooves 6, and the bottom of the mounting groove 6 and the top of the second limiting groove 5 are on the same horizontal plane. The bottom of the adjustment frame 2 is fixedly connected with a support plate 16, and a support spring 18 is fixedly installed between the support plate 16 and the top of the inner wall of the base 1. The support spring 18 is sleeved on a limiting rod 17, and the limiting rod 17 is fixedly installed on the top of the inner wall of the base 1. The limiting rod 17 slides and passes through the support plate 16.

[0023] The adjustment mechanism includes: a motor 13, which is fixedly installed on the inner wall of the base 1; the output shaft of the motor 13 is fixedly connected to a threaded rod 11, which is rotatably installed on a mounting bracket 10, which is fixedly installed on the base 1; a lifting plate 12 is threadedly installed on the threaded rod 11, and a lifting block 7 is fixedly connected to the lifting plate 12, which is slidably installed in the mounting groove 6; a roller shaft 15 is rotatably installed on the lifting block 7, and the lifting block 7 is located at both ends of the roller shaft 15; a pressure roller 14 is fixedly installed on the roller shaft 15, the length of the pressure roller 14 is equal to the length of the second limiting groove 5, and the diameter of the pressure roller 14 is the same as the height of the lifting block 7; connecting plates 8 are fixedly connected to both sides of the lifting block 7, and lifting rods 3 are fixedly connected to the connecting plates 8; the lifting rods 3 slide and pass through the slot 20, and the feeding port is closed by the lifting rods 3, so that the second limiting groove 5 can limit the bottom film.

[0024] The motor 13 drives the threaded rod 11 to rotate, which in turn causes the lifting plate 12 to lift the lifting block 7. The lifting block 7 then drives the roller shaft 15 to descend, which in turn drives the pressing roller 14 to descend, allowing the pressing roller 14 to press the high-resilience conductive foam tightly. In the prior art, when the pressing roller 14 presses and bonds the high-resilience conductive foam, the bonding effect is poor, and the high-resilience conductive foam cannot be pressed tightly and bonded to the base film. Therefore, an adjustment mechanism is set up. When the lifting block 7 rises, it drives the connecting plate 8 to rise, and the connecting plate 8 drives the lifting rod 3 to rise. When the lower end of the lifting rod 3 moves above the feeding trough 9, the feeding port is opened, which facilitates the movement of the base film and the slit conductive foam to directly below the pressing roller 14, making it easier to open the feeding port. When the lifting block 7 descends, it drives the roller shaft 15 and the pressing roller 14 to descend, allowing the pressing roller 14 to contact and squeeze the high-resilience conductive foam, so that the conductive foam is tightly bonded to the base film.

[0025] Working principle:

[0026] When motor 13 is started, its output shaft rotates forward, driving the threaded rod 11 to rotate, causing the lifting block 7 to rise. The lifting plate 12 then drives the lifting block 7 to rise, which in turn drives the connecting plate 8 to rise. The connecting plate 8 then drives the lifting rod 3 to rise. When the lower end of the lifting rod 3 moves above the feeding trough 9, the feeding port opens, facilitating the movement of the bottom film and the slitting conductive foam directly below the covering roller 14. The motor 13 then rotates in reverse, causing the lifting plate 12 to drive the lifting block 7 to descend. The lifting block 7 then drives the roller shaft 15 to descend, which in turn drives the covering roller 14 to descend, thus lowering the covering... The pressure roller 14 can contact and squeeze the highly resilient conductive foam, making the conductive foam adhere tightly to the base film. For the thinner highly resilient conductive foam, the lifting block 7 contacts the lower end of the mounting groove 6 and presses down the adjusting frame 2. The adjusting frame 2 slides in the sliding groove, and the adjusting frame 2 drives the support plate 16 to descend. The support plate 16 pulls the spring, and the pressure roller 14 continues to descend, which can press the highly resilient conductive foam tightly. The position of the first limiting groove 4 also descends, which can position the slit conductive foam, so that the device can bond highly resilient conductive foam of different thicknesses.
