Description

Technical Field

[0001] This application relates to the field of conductive foam coating equipment, and in particular to a conductive foam wrapping device. Background Technology

[0002] Conductive foam is a commonly used electromagnetic shielding material. During production, a conductive film needs to be wrapped around the outside of the foam to achieve a conductive shielding effect.

[0003] In the actual production process, existing conductive foam wrapping equipment requires folding and pasting the conductive film onto the foam. During the folding process, sheets are usually used to guide the folding. The conductive film is prone to deformation and wear due to repeated prying of the sheet used for folding the conductive film over a long period of time. At the same time, when producing conductive foam products of different specifications, it is necessary to change the sheet components of different sizes.

[0004] The sheet metal in existing equipment is mostly fixed to the movable plate by multiple bolts. When disassembling and replacing the dial plate, multiple bolts need to be loosened and tightened one by one, which is cumbersome and time-consuming. Moreover, after replacement, multiple dial plates are prone to positional shifts and misalignments, which require manual alignment, affecting production changeover efficiency and making the equipment less convenient to operate. Summary of the Invention

[0005] To improve the ease of operation of conductive foam wrapping equipment, this application provides a conductive foam wrapping device.

[0006] This application provides a conductive foam wrapping device, which adopts the following technical solution: A conductive foam wrapping device includes a machine tool with a worktable mounted on it, a pressing component for pressing the foam, a folding component for folding a conductive film, and a folding component for flipping the conductive film. The folding component includes a second cylinder mounted on the machine tool, a gripper cylinder connected to the second cylinder, a movable plate connected to the gripper cylinder, a detachable paddle plate mounted on the movable plate, and a paddle connected to the paddle plate.

[0007] By adopting the above technical solution, the push-fold component first folds the conductive film on the worktable upwards, and the flip-fold component's paddle further folds the conductive film to cover the top surface of the foam. The paddle is detachably mounted on the movable plate. When the paddle is worn or deformed, or when different specifications of paddle need to be replaced due to production changes, the paddle can be quickly disassembled and assembled without the need for a large number of bolts, thus improving the ease of operation of the equipment.

[0008] In one specific implementation scheme, a screw is rotatably mounted on the movable plate, a guide rod is mounted on the movable plate, a buckle plate is threadedly connected to the screw, the buckle plate is slidably connected to the guide rod, a slot for accommodating the buckle plate is opened on the dial plate, a buckle platform is mounted on the buckle plate, a buckling groove for inserting the buckle platform is opened on the dial plate, and an abutment platform is formed on the dial plate to abut against the movable plate.

[0009] By adopting the above technical solution, rotating the screw can drive the buckle plate to move up and down along the guide rod; when assembling the lever plate, align the slot of the lever plate with the buckle plate and insert it, so that the buckle platform is embedded in the buckling groove. Rotating the screw raises the buckle plate, causing the lever plate to move up until it presses against the platform and adheres to the movable plate. The lever plate is quickly locked and fixed by the engagement of the buckle platform and the buckling groove; rotating the screw in the opposite direction releases the lever plate. The disassembly and assembly operation is simple and does not require disassembling and assembling multiple fasteners.

[0010] In one specific implementation scheme, a fixed rod is installed on the movable plate, a slide plate is slidably installed on the fixed rod, a first spring is sleeved on the fixed rod, one end of the first spring is connected to the slide plate and the other end is connected to the movable plate, a telescopic sleeve is installed on the slide plate, a telescopic rod is slidably installed on the telescopic sleeve, a baffle is installed on the telescopic rod, a second spring is sleeved on the telescopic rod, one end of the second spring is connected to the baffle and the other end is connected to the slide plate, a guide plate is installed on the buckle plate, a guide slope is formed on the guide plate, and the slide plate abuts against the guide slope.

[0011] By adopting the above technical solution, during the lifting of the buckle plate with the screw, the guide plate is lifted synchronously, and the guide slope squeezes the slide plate to overcome the elastic force of the first spring and slide; the slide plate drives the baffle to abut against the side wall of the lever plate, and the second spring provides elastic clamping force, automatically pushing the lever plate to the positioning reference position, completing the automatic alignment and correction of the lever plate, and preventing the lever plate from tilting; when disassembling the lever plate, the buckle plate moves down, the guide slope releases the squeezing of the slide plate, the first spring drives the slide plate to reset, and the baffle automatically disengages from the lever plate, without affecting the removal of the lever plate.

[0012] In one specific implementation, the cross-section of the buckle is trapezoidal.

[0013] By adopting the above technical solution, the trapezoidal buckle platform has a guiding function in the buckling groove. During the buckle plate lifting and locking process, the trapezoidal buckle platform can generate a lateral component force on the lever plate, which helps the lever plate to find the correct position.

[0014] In one specific implementation, a second arc-shaped surface is provided on the side of the paddle that contacts the conductive film.

[0015] By adopting the above technical solution, the paddle relies on the second arc-shaped surface to contact and push the conductive film. The arc-shaped surface transition is smooth, avoiding sharp edges from cutting or scratching the conductive film and ensuring the integrity of the film material during the folding process.

[0016] In one specific implementation, the push-folding assembly includes a first cylinder mounted on the machine tool, the output shaft of the first cylinder being connected to a push plate, and a pusher plate for pushing and folding the conductive film being connected to the push plate.

[0017] By adopting the above technical solution, the first cylinder drives the push plate to rise and fall, which in turn drives the push plate to move. The push plate lifts the conductive film at the worktable from bottom to top, completing the initial upward folding of the conductive film and preparing for the secondary folding of the subsequent folding component.

[0018] In one specific implementation, the pusher has a first arc-shaped surface on the side that contacts the conductive film, and an insertion hole is provided on the worktable, into which the pusher is inserted.

[0019] By adopting the above technical solution, the pusher extends out of the worktable surface through the socket, and the first arc surface contacts the conductive film, smoothly pushing up the conductive film and reducing the risk of the conductive film being scratched; the socket plays a role in limiting and guiding the movement of the pusher, ensuring the stability of the pusher's movement trajectory.

[0020] In one specific implementation, the pressing assembly includes a slide table mounted on the machine tool, and a pressure block is connected to the slide table.

[0021] By adopting the above technical solution, the slide table drives the pressure block to move vertically up and down. The pressure block can press down to press and stick the conductive film that has been folded to the top surface of the foam onto the surface of the foam, thus completing the conductive foam wrapping and pressing operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The folding component of this application has a detachable lever plate that can be mounted on a movable plate. The lever plate and the latching platform are locked together by a screw. When the lever plate is disassembled or assembled, it is not necessary to disassemble or assemble multiple bolts. When the lever plate is worn or the product is changed, it is easy to disassemble and replace, thus improving the ease of operation of the equipment.

[0023] 2. While the buckle plate is raised and locking the lever plate, the guide slope drives the slide plate and the baffle plate to elastically abut against the lever plate, automatically completing the alignment and correction of the lever plate, avoiding tilting and misalignment after the lever plate is assembled, and reducing the manual correction process.

[0024] 3. The pusher is set with a first arc surface and the paddle is set with a second arc surface, which makes it less likely to scratch the conductive film during the pushing and folding process, thus improving the product yield. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0037] This application discloses a conductive foam wrapping device, referring to... Figure 1 and Figure 2The system includes a machine tool 1, a worktable 11 fixedly mounted on the machine tool 1, a pressing component 2 for pressing foam mounted on the machine tool 1, a pushing and folding component 3 for pushing and folding conductive film and a flipping component 4 for flipping conductive film mounted on the machine tool 1, and the pushing and folding component 3 and the flipping component 4 are respectively arranged on both sides of the worktable 11.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The push-folding assembly 3 includes a first cylinder 31, which is fixedly mounted on the machine tool 1. The first cylinder 31 is located below the worktable 11 and faces the worktable 11. The output shaft of the first cylinder 31 is fixedly connected to a push plate 32. Four push plates 33 are fixedly connected to the push plate 32. A first arc-shaped surface 331 is opened on the side of the push plates 33 that are close to each other.

The slide table 21 is an electric slide table, which is the prior art. A pressure block 22 is connected to the slide table 21. The slide table 21 can control the pressure block 22 to move in the vertical direction. The pressure block 22 has a beveled surface 221.

[0040] Reference Figure 5 and Figure 6 The folding assembly 4 includes a second cylinder 41, which is fixedly mounted on the machine tool 1. A gripper cylinder 42 is connected to the second cylinder 41, and the second cylinder 41 can control the gripper cylinder 42 to move in the vertical direction. A movable plate 43 is connected to the gripper toe of the gripper cylinder 42, and a lever plate 44 is detachably mounted on the movable plate 43. A lever 444 is fixedly connected to the lever plate 44, and a second arc-shaped surface 445 is formed on the side of the lever 444 that contacts the conductive film.

[0041] Reference Figure 7 , Figure 8 and Figure 9 A screw 451 is rotatably mounted on the movable plate 43, and a guide rod 452 is fixedly mounted on the movable plate 43. A buckle plate 453 is threadedly connected to the screw 451, and the buckle plate 453 is slidably connected to the guide rod 452. A slot 441 for accommodating the buckle plate 453 is provided on the lever plate 44, and a buckle platform 454 is mounted on the buckle plate 453. The buckle platform 454 has a trapezoidal cross-section. A buckling groove 443 for inserting the buckle platform 454 is provided on the lever plate 44, and an abutment 442 is formed on the lever plate 44 to abut against the movable plate 43.

[0042] During the production and processing, the paddle 444 may deform, causing the conductive film to not be pressed properly. In this case, the paddle 44 needs to be replaced, or the paddle 44 may need to be replaced with a paddle of a different size. In this case, the paddle 44 is inserted into the buckle plate 453, and the buckle 454 is lowered into the buckling groove 443. The buckle plate 453 supports the weight of the paddle 44. Then, the screw 451 is rotated, and the screw 451 controls the buckle plate 453 to rise. The buckle plate 453 drives the paddle 44 to rise, so that the abutment 442 on the paddle 44 abuts against the movable plate 43, thereby completing the fixation of the paddle 44.

[0043] Reference Figure 8 , Figure 9 and Figure 10 A fixed rod 461 is fixedly installed on the movable plate 43. A sliding plate 462 is slidably installed on the fixed rod 461. A first spring 463 is sleeved on the fixed rod 461. One end of the first spring 463 is fixedly connected to the sliding plate 462, and the other end is fixedly connected to the movable plate 43. A telescopic sleeve 464 is fixedly installed on the sliding plate 462. A telescopic rod 465 is slidably installed on the telescopic sleeve 464. A baffle 466 is fixedly installed on the telescopic rod 465. A second spring 467 is sleeved on the telescopic rod 465. One end of the second spring 467 is fixedly connected to the baffle 466, and the other end is fixedly connected to the sliding plate 462. A guide plate 468 is fixedly installed on the buckle plate 453. A guide slope 4681 is formed on the guide plate 468, and the sliding plate 462 abuts against the guide slope 4681.

[0044] During the lifting process of the buckle plate 453, the buckle plate 453 will drive the guide plate 468 to rise. The guide plate 468 will abut against the slide plate 462. Through the action of the guide ramp 4681, the guide plate 468 will push the slide plate 462 to slide. The slide plate 462 will drive the baffle plate 466 to move so that the baffle plate 466 abuts against the lever plate 44. Through the elastic support of the second spring 467, the baffle plate 466 will assist in pushing the lever plate 44 to move uniformly towards the side closer to the gripper cylinder 42, thereby positioning the lever plate 44 and making the four lever plates 44 neatly aligned. At the same time, by the baffle plate 466 pressing against the side wall of the lever plate 44, it can help guide the lever plate 44 to be in a vertical state during the tightening process, and prevent the lever plate 44 from tilting.

[0045] When wrapping conductive foam, first place the conductive film on the workbench 11, then place the foam on the conductive film. The foam will be between the sockets 111. The first cylinder 31 controls the push plate 32 to rise. The push plate 32 drives the push piece 33 to move. The push piece 33 pushes the conductive film on the side of the foam to fold upward. Then, the second cylinder 41 controls the movable plate 43 to descend, causing the paddle 444 to stop at the side of the foam. Next, the slide 21 controls the pressure block 22 to rise, causing the pressure block 22 to leave the foam surface. The gripper cylinder 42 controls the movable plates 43 to move closer together, causing the paddle 444 to push the conductive film to fold onto the top surface of the foam. Then, the slide 21 controls the pressure block 22 to descend, causing the pressure block 22 to stop above the paddle 444. Next, the gripper cylinder 42 controls the movable plate 43 to move, causing the paddle 444 to leave the stroke of the pressure block 22. Then, the slide 21 controls the pressure block 22 to press down, pressing and sticking the conductive film onto the top surface of the foam.

[0046] The implementation principle of this application embodiment is as follows: the device completes the initial upward folding of the conductive film through the push-folding component 3, and the flipping component 4 realizes the secondary folding of the conductive film to the top surface of the foam. The pressing component 2 completes the pressing and bonding. The lever 44 of the flipping component 4 adopts a quick-release structure. The lever 44 can be locked and released by rotating the screw 451, which is convenient for disassembly and assembly. During the locking process, the lever 44 is automatically aligned and corrected by the cooperation of the guide slope 4681, the slide plate 462, and the baffle 466, which reduces the time for manual correction and improves the ease of operation of the conductive foam wrapping equipment.

[0047] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
