Description

Technical Field

[0001] This utility model relates to the field of tape bending technology, specifically an automatic tape bending mechanism. Background Technology

[0002] Aluminum foil tape, made with high-quality pressure-sensitive adhesive, boasts excellent adhesion, strong bonding, and anti-aging properties. It can be used in various electronic products such as PDAs, PDPs, LCD monitors, laptops, and copiers where electromagnetic shielding is required. With the rapid development of the electronics industry and the fast pace of technological updates, electronic products like laptops are constantly being upgraded. Aluminum foil tape in laptops can serve both conductive and shielding functions, blocking interference signals and improving image processing and display effects. Currently, the majority of aluminum foil tape applications in laptops involve directly attaching it to electronic components requiring heat conduction, electrical conductivity, or shielding. Because different electronic components in laptops generate varying levels of conductivity and heat, and because the application process is relatively cumbersome, the aluminum foil tape needs to be pre-bent. However, this is typically done manually, which is costly and inefficient. Utility Model Content

[0003] The present invention provides an automatic tape bending mechanism to solve the problems of high labor costs and low efficiency caused by manually bending aluminum foil tape.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An automatic tape bending mechanism includes a worktable with a mating frame, a rotating device on the mating frame, a turntable on the rotating device, a tape feeding device on the worktable, multiple tape pulling and fixing devices distributed on the turntable, and a tape bending device on the worktable. In use, the tape feeding device fixes and feeds the tape material. The tape pulling and fixing devices pull the fed tape to the corresponding bending position on the turntable, simultaneously positioning the tape on the turntable. The turntable rotates to change the position of the tape and its corresponding components, moving the fixed tape to the corresponding position of the tape bending device. The tape bending device then bends the tape. The rotating device continues to rotate the turntable, moving the bent tape and allowing the next tape to be bent. Finally, the tape pulling and fixing devices are released, and the bent tape is removed. The structure of this application allows the rotating device to drive the turntable and related components to rotate, thereby driving the conveyor belt to rotate. This reduces the overall footprint of the equipment and allows multiple conveyor belt pulling and fixing devices to work simultaneously at multiple stations, improving production efficiency. Simultaneously, the conveyor belt discharge device can fix and discharge the conveyor belt, and the conveyor belt pulling and fixing device can pull the conveyor belt to the corresponding position on the turntable, ensuring accurate and fixed pulling distance. This guarantees accurate positioning of the conveyor belt on the turntable, preventing significant bending position deviations during bending. The overall conveyor belt bending method reduces labor costs and improves production efficiency.

[0006] Furthermore, the rotating device includes a motor mounted on the mounting frame and a connecting seat located at the output end of the motor, with the turntable fixedly connected to the connecting seat. This structure allows the connecting seat to rotate via the motor, thereby causing the turntable fixedly connected to the connecting seat to rotate. The overall structure is simple and practical.

[0007] Furthermore, the tape discharging device includes a mounting bracket mounted on the worktable. A mounting roller and a guide roller are rotatably connected to the mounting bracket. A tape clamping assembly and a tape cutting assembly are mounted on the mounting bracket, corresponding to the outer side of the guide roller. This structure allows the roll of tape to be fixed to the mounting roller and guided by the guide roller. After the tape is initially pulled out and clamped by the tape clamping assembly, the tape can be pulled by the tape pulling and fixing device, thus discharging the tape. During the subsequent tape pulling and fixing, the tape clamping assembly does not clamp the tape. Once the tape is pulled to the desired position, the tape clamping assembly clamps it, facilitating cutting the tape using the tape cutting assembly after fixing. A rotating device then rotates the corresponding components, and the above operations are repeated. The tape cutting assembly can utilize existing technology, as long as it can achieve tape cutting and separation.

[0008] Furthermore, the tape clamping assembly includes a lower crossbeam mounted on the mounting bracket, an upper crossbeam mounted on the lower crossbeam, a clamping cylinder mounted on the upper crossbeam, and a clamping block mounted on the output end of the clamping cylinder. With this structure, the clamping block can be moved up and down by the clamping cylinder, thereby using the clamping block in conjunction with the lower crossbeam to achieve the clamping and fixing of the tape.

[0009] Furthermore, the tape pulling and fixing device includes a mounting frame mounted on the turntable, a displacement cylinder mounted on the mounting frame, an upper fixing block mounted on the output end of the displacement cylinder, a connecting frame mounted on the upper fixing block, a fixing cylinder mounted on the connecting frame, a lower fixing block mounted on the fixing cylinder, a support plate mounted on the lower fixing block, and a pressing cylinder mounted on the mounting frame. The pressing cylinder has a positioning block that cooperates with the support plate to fix the tape. The turntable has an opening groove that cooperates with the support plate. The mounting frame has a displacement channel that facilitates the movement of the upper fixing block and other components, allowing the displacement cylinder to drive the upper fixing block and other components to move within the displacement channel. This structure allows the upper fixing block and related components to move horizontally via a displacement cylinder, and the lower fixing block and support plate to move vertically via a fixing cylinder. Once the support plate reaches the lower position of the tape and the upper fixing block reaches the upper position, the tape end is initially fixed by the upward-moving support plate in conjunction with the upper fixing block. Then, the displacement cylinder resets, causing the tape to move until it reaches a preset position. Finally, the downward-pressing cylinder causes the positioning block to move downward, thus fixing the tape to the support plate. The overall structure allows for tape displacement, support via the support plate, and effective tape fixation.

[0010] Furthermore, the tape bending device includes a frame, a lifting cylinder mounted on the frame, a mounting platform at the output end of the lifting cylinder, an upper limit block on the mounting platform, and a rotating bending component on one side of the upper limit block; a suction cup assembly is disposed within the upper limit block. The suction cup assembly can be any type from existing technologies, as long as it can adsorb the tape, thereby cooperating with the upper limit block to fix the tape's position and facilitate bending. In use, the lifting cylinder can move the mounting platform up and down, adjusting its position so that the upper limit block is positioned above the tape. The suction cup assembly adsorbs the upper side of the tape, thus limiting its position. Then, the rotating bending component rotates, causing part of the tape to rotate, thereby bending the tape. During bending, the upper limit block supports the tape, resulting in a better bending effect.

[0011] Furthermore, the rotary bending assembly includes a bending frame mounted on the mounting platform. A shaft is rotatably connected to the bending frame, and a bending block is positioned below the upper limit block on the shaft. A gear is mounted on the shaft, and a driving cylinder is mounted on the mounting platform. A rack meshing with the gear is located at the output end of the driving cylinder, and the rack moves up and down under the drive of the driving cylinder. With this structure, the rack can be moved up and down by the driving cylinder, thereby rotating the gear meshing with the rack. The rotation of the gear drives the shaft to rotate, and the rotation of the shaft drives the bending block to rotate, thus using the bending block in conjunction with the upper limit block to bend the tape.

[0012] Beneficial effects: In use, the tape feeding device fixes and feeds the tape material, while the tape pulling and fixing device pulls the fed tape to the corresponding bending position on the turntable. Simultaneously, the tape pulling and fixing device positions the tape on the turntable. The turntable rotates to change the position of the tape and corresponding components, causing the fixed tape to rotate to the corresponding position of the tape bending device. The tape bending device then bends the tape. The rotating device continues to drive the turntable to rotate, thus moving the bent tape and allowing the next tape to be bent. Finally, the tape pulling and fixing device is opened, and the bent tape is removed. The structure of this application allows the rotating device to drive the turntable and related components to rotate, thereby driving the conveyor belt to rotate. This reduces the overall footprint of the equipment and allows multiple conveyor belt pulling and fixing devices to work simultaneously at multiple stations, improving production efficiency. Simultaneously, the conveyor belt discharge device can fix and discharge the conveyor belt, and the conveyor belt pulling and fixing device can pull the conveyor belt to the corresponding position on the turntable, ensuring accurate and fixed pulling distance. This guarantees accurate positioning of the conveyor belt on the turntable, preventing significant bending position deviations during bending. The overall conveyor belt bending method reduces labor costs and improves production efficiency. Attached Figure Description
