Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, specifically to a conductive foam bonding fixture. 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.

[0003] A search revealed, for example, a utility model patent with Chinese patent publication number CN222004439U, which discloses a conductive foam bonding fixture. The fixture includes a base, which is square in shape. An adjustment box is mounted 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 adjustment of the adjustment plate and the adjustment box, causing the adjustment box to lift a protrusion and separate it from the slot. A gap is created between one end of the adjustment box and the base, facilitating the placement of strips of the base film and conductive foam into the first and second limiting grooves. This guides and limits the placement of the base film and conductive foam. The pressure roller compresses the strips of base film and conductive foam, facilitating bonding. The adjustment mechanism also allows for the height adjustment 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] In this patent, the height of the adjustment box is adjusted by two screws. In actual operation, it is indeed necessary to operate with both hands simultaneously or adjust in two separate times, which is relatively time-consuming and labor-intensive. Furthermore, if the adjustment amount of the two screws is inconsistent, the force on the adjustment box will be uneven, which will lead to the adjustment box tilting and ultimately affect the alignment of the limit groove or the uneven force on the pressure roller. These problems will have an adverse effect on the bonding effect of the conductive foam. Therefore, a conductive foam bonding fixture is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a conductive foam bonding fixture, which has the advantages of convenient and precise height adjustment. It solves the problem in the prior art where the height of the adjustment box is adjusted by two screws, which in actual operation requires simultaneous operation of both hands or adjustment in two separate steps.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conductive foam bonding fixture, comprising a functional box, two guide components being provided on the top of the functional box, a pressing component being provided on the top of the functional box between the two guide components, and an adjustment mechanism being provided inside the functional box;

[0007] The adjustment mechanism includes a bidirectional threaded rod, on the outer surface of which are threadedly connected two active blocks. A movable plate is movably installed inside the functional box, and two driven blocks are fixedly installed at the bottom of the movable plate. Limit blocks are fixedly installed at the bottom of each of the two active blocks. Two limit grooves adapted to the limit blocks are opened on the inner bottom wall of the functional box.

[0008] Furthermore, both of the guide components include guide plates, and the bottom of both guide plates is provided with a bottom film guide groove and a conductive foam slitting guide groove.

[0009] Furthermore, the covering assembly includes a support frame, on the inner side of which a covering roller is rotatably mounted, and on the front side of which a digital display bar is provided.

[0010] Furthermore, both of the guide components and the pressure-covering components are fixedly installed on the top of the movable plate, and the top of the functional box has a through-hole adapted to the two guide plates and the support frame.

[0011] Furthermore, the left and right inner walls of the functional box are each provided with a sliding groove that is compatible with the movable plate.

[0012] Furthermore, one end of the bidirectional threaded rod passes through the left side of the functional box and is fixedly installed with a knob. The tops of the two active blocks and the bottoms of the two driven blocks are both inclined surfaces, and the two inclined surfaces are in contact and compatible with each other.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This conductive foam bonding fixture, through the bidirectional threaded rod and the inclined structure of the active and driven blocks in the adjustment mechanism, allows the operator to simultaneously adjust the height of both sides of the movable plate by simply turning a knob. Compared with the traditional double-screw adjustment method, the operation is simpler and can effectively avoid the problem of adjustment tilt caused by inconsistent adjustment on both sides, thus ensuring the accuracy of the height adjustment of the guide component and the pressing component.

[0015] 2. The conductive foam bonding fixture has a digital display bar on the front of the support frame that can intuitively display the height of the bonding component. Operators can quickly and accurately adjust the height of the bonding roller according to the different thicknesses of conductive foam, thereby improving production efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 In this embodiment, a conductive foam bonding fixture includes a functional box 1. The top of the functional box 1 is provided with two guide components 2, and the top of the functional box 1 is provided with a pressing component 3 located between the two guide components 2. An adjustment mechanism 4 is provided inside the functional box 1.

[0023] The adjustment mechanism 4 includes a bidirectional threaded rod 401, with two active blocks 402 threadedly connected to the outer surface of the bidirectional threaded rod 401. A movable plate 403 is movably installed inside the function box 1. Two driven blocks 404 are fixedly installed at the bottom of the movable plate 403. Limit blocks 405 are fixedly installed at the bottom of each of the two active blocks 402. Two limit grooves 406 adapted to the limit blocks 405 are opened on the inner bottom wall of the function box 1.

[0024] In the adjusting mechanism 4, the outer surface of the bidirectional threaded rod 401 is threaded with two driving blocks 402. When the bidirectional threaded rod 401 is rotated, the two driving blocks 402 will move towards or away from each other on the bidirectional threaded rod 401 based on the principle of threaded transmission. To ensure that the driving blocks 402 can only move horizontally, a limiting block 405 is fixedly installed at the bottom of the driving block 402. A matching limiting groove 406 is provided on the bottom wall of the inner wall of the functional box 1. The limiting block 405 slides in the limiting groove 406, restricting the movement of the driving block 402. In addition, a movable plate 403 is movably installed inside the functional box 1. Two driven blocks 404 are fixed at the bottom of the movable plate 403. The top of the active block 402 and the bottom of the driven block 404 are both inclined surfaces, and the two inclined surfaces are adapted to each other. When the active block 402 moves horizontally, its inclined surface interacts with the inclined surface of the driven block 404, converting the horizontal force of the active block 402 into the vertical force of the driven block 404, thereby driving the movable plate 403 to rise or fall, so as to realize the synchronous adjustment of the height of the guide component 2 and the pressure component 3.

[0025] By opening sliding grooves on the left and right inner walls of the functional box 1 to match the movable plate 403, the stability of the movable plate 403 when moving up and down is improved. By opening through holes on the top of the functional box 1 to match the two guide plates 201 and the support frame 301, it is convenient to connect the guide plates 201 and the support frame 301 with the movable plate 403.

[0026] The guide assembly 2 includes a guide plate 201, and a bottom film guide groove 202 and a conductive foam slitting guide groove 203 are provided at the bottom of the guide plate 201. These two guide grooves allow the bottom film and conductive foam slitting to pass through.

[0027] The pressing assembly 3 consists of a support frame 301 and a pressing roller 302. The pressing roller 302 is rotatably mounted inside the support frame 301. When the movable plate 403 drives the pressing assembly 3 to adjust to a suitable height, the pressing roller 302 can uniformly squeeze the bottom film and conductive foam strips guided by the guide assembly 2 to achieve a tight fit between the two. In addition, the digital display bar set on the front of the support frame 301 can intuitively display the height of the pressing assembly 3, which makes it convenient for operators to accurately adjust the height of the pressing roller 302 according to the conductive foam of different thicknesses, further improving the bonding effect.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, place the bottom film and conductive foam strips into the bottom film guide groove 202 and conductive foam strip guide groove 203 at the bottom of the guide plate 201, respectively, and use the guide grooves to limit their position;

[0030] 2) Then, according to the thickness of the conductive foam, rotate the knob at the end of the bidirectional threaded rod 401. The bidirectional threaded rod 401 drives the active block 402 to move horizontally. The active block 402 pushes the driven block 404 through the inclined surface, so that the movable plate 403 drives the guide assembly 2 and the covering assembly 3 to rise and fall. At the same time, observe the digital display bar on the front side of the support frame 301 and adjust the covering roller 302, the bottom film guide groove 202, and the conductive foam slitting guide groove 203 to the appropriate height simultaneously.

[0031] 3) When the conductive foam slitting of the bottom film passes through the covering roller 302, the covering roller 302 rotates on the support frame 301 to achieve bonding.

[0032] In summary, this conductive foam bonding fixture, through the inclined structure of the bidirectional threaded rod 401 and the active block 402 and driven block 404 in the adjustment mechanism 4, allows the operator to simultaneously adjust the height of both sides of the movable plate 403 by simply turning a knob. Compared with the traditional twin-screw adjustment method, the operation is simpler and can effectively avoid the problem of adjustment tilt caused by inconsistent adjustment amounts on both sides, ensuring the accuracy of height adjustment of the guide component 2 and the covering component 3.

[0033] Furthermore, the digital display bar on the front of the support frame 301 can intuitively display the height of the covering component 3, allowing operators to quickly and accurately adjust the height of the covering roller 302 according to the different thicknesses of conductive foam, thereby improving production efficiency.
