Description

Technical Field

[0001] This application relates to the field of steel strip winding technology, and in particular to an auxiliary winding device for steel strip used in the production of heat sink fins. Background Technology

[0002] Heat sink fins are a common passive heat dissipation component in electronic engineering design. They are usually attached to a heat-generating surface and use thermal conduction to transfer heat from the heat source to the fins, and then dissipate the heat into the air through convection.

[0003] When steel strip is used to produce heat sink fins, the coiled steel strip needs to be unwound by an unwinding machine. Due to the large weight of the steel coil, the traditional method is to use a truss with chains or cloth belts to hoist the steel coil onto the unwinding machine.

[0004] In actual hoisting operations, the steel belt has a large inertia. When the steel belt moves, the chain or cloth belt moves with it, which leads to poor stability and high risk. It also affects the winding efficiency of the steel belt, which is a significant drawback. Utility Model Content

[0005] To improve the efficiency, safety, and stability of steel coil winding, this application provides an auxiliary winding device for steel strips used in the production of heat dissipation fins.

[0006] The technical solution provided in this application for an auxiliary winding device for steel strip in heat sink fin production is as follows:

[0007] A steel strip auxiliary winding device for heat dissipation fin production includes a support arranged next to an unwinding device, a movable frame placed on the support, a movable component for driving the movable frame to move closer to or away from the unwinding device, and a support frame for carrying the steel coil arranged on the movable frame.

[0008] By adopting the above technical solution, workers use handling tools to place the steel coil on the support frame. Then, under the action of the moving component, the moving frame moves the steel coil closer to the unwinding device until the steel coil is completely moved onto the unwinding device, after which the moving frame retracts. Compared with truss hoisting of steel coils, the movement of the moving frame on the support to achieve the coil winding process is more stable, safer, and more efficient.

[0009] Optionally, the moving component includes a track arranged on a support and rollers rolling on the track. A motor electrically connected to the control system is arranged inside the moving frame, and the output shaft of the motor is connected to the rollers.

[0010] By adopting the above technical solution, the control system starts the motor, the output shaft of the motor drives the roller to rotate, and the roller rolls on the support, thereby realizing the movement of the mobile frame on the support.

[0011] Optionally, the movable frame is also equipped with a plurality of telescopic cylinders electrically connected to the control system, and the piston rods of the telescopic cylinders are connected to the support frame.

[0012] By adopting the above technical solution, the control system activates the telescopic cylinder, and the piston rod of the telescopic cylinder pushes the support frame upward, thereby raising the steel coil to the upper winding height. After the upper winding is completed, the piston rod of the telescopic cylinder retracts downward, thereby creating a gap between the support frame and the steel coil, facilitating the retraction of the moving frame.

[0013] Optionally, the top of the support frame is V-shaped.

[0014] By adopting the above technical solution, the steel coil is placed more stably on the support frame and is less prone to shaking.

[0015] Optionally, the support frame has elastic protective pads arranged on the sidewalls that come into contact with the steel coil.

[0016] By adopting the above technical solution, the elastic protective pad protects the outermost part of the steel coil, reducing the possibility of damage to the steel coil.

[0017] Optionally, a guide frame is arranged between the movable frame and the support frame, and the piston rod of each telescopic cylinder slides through the guide frame.

[0018] By adopting the above technical solution, the guide frame plays a role in tensioning and linkage of the piston rods of each telescopic cylinder. Even if the steel coil is placed on the support frame with a lateral deviation, the support frame can stably support the steel coil.

[0019] Optionally, the bottom of the support frame is provided with a lifting rod that slides into the movable frame, and the lifting rod is supported by compression springs on both sides opposite to the guide frame.

[0020] By adopting the above technical solution, during the extension of the piston rod of the telescopic cylinder, the compression spring pushes the guide frame to gradually rise, thereby improving the support effect on the extended piston rod.

[0021] Optionally, the movable frame is provided with a proximity switch electrically connected to the control system, and the unwinding device is provided with a sensing block for being sensed by the proximity switch.

[0022] By adopting the above technical solution, the proximity switch and the sensing block work together to limit the minimum gap between the moving frame and the unwinding device, thereby reducing the possibility of the moving frame moving too far and colliding with the unwinding device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Workers use handling equipment to place the steel coil on the support frame. Then, under the action of the moving component, the moving frame moves the steel coil closer to the unwinding device until the steel coil is completely moved onto the unwinding device, after which the moving frame retracts. Compared with truss hoisting of steel coils, the movement of the moving frame on the support to achieve the coil winding process is more stable, safer, and more efficient.

[0025] 2. The control system activates the telescopic cylinder, whose piston rod pushes the support frame upward, thereby raising the steel coil to the upper winding height. After the upper winding is completed, the piston rod of the telescopic cylinder retracts downward, creating a gap between the support frame and the steel coil, facilitating the retraction of the moving frame.

[0026] 3. The guide frame plays a role in tensioning and linkage of the piston rods of each telescopic cylinder. Even if the steel coil is placed on the support frame with a lateral deviation, the support frame can stably support the steel coil. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses an auxiliary winding device for steel strip used in the production of heat sink fins.

[0032] Reference Figure 1 The auxiliary winding device for steel strip used in heat dissipation fin production includes a support 1 placed next to and welded to the unwinding device. A movable frame 2 is placed on the support 1. The movable frame 2 is rectangular and hollow inside. Movable components for driving it to move closer to or away from the unwinding device are arranged inside the movable frame 2.

[0033] Reference Figure 1 and Figure 2 The moving component includes a motor 6 bolted inside the moving frame 2 and electrically connected to the control system. The motor 6 is a conventional forward and reverse servo dual-axis motor, and rollers 5 are fixedly mounted on both output shafts of the motor 6. A track 4 is bolted to the support 1, and the rollers 5 are located on the track 4.

[0034] Reference Figure 1 and Figure 2 The worker starts the motor 6 through the control system. The output shaft of the motor 6 drives the roller 5 to rotate, thereby moving the frame 2 closer to or further away from the unwinding device.

[0035] A proximity switch 12 is threaded onto the movable frame 2. The proximity switch 12 is electrically connected to the control system. A sensing block 13 is embedded on the unwinding device for being sensed by the proximity switch 12. In this way, the proximity switch 12 and the sensing block 13 cooperate to limit the minimum distance between the unwinding device and the movable frame 2.

[0036] Reference Figure 1 and Figure 2 The top of the mobile frame 2 is equipped with a support frame 3 for carrying steel coils. The top of the support frame 3 is V-shaped. When the worker places the steel coil on the support frame 3, the steel coil can remain stable during the process of the mobile frame 2 driving the support frame 3 to achieve the winding. The risk is low and the winding efficiency is high.

[0037] Reference Figure 1 The support frame 3 has an elastic protective pad 8 bonded to the side wall that contacts the steel coil. The elastic protective pad 8 is made of rubber material and protects the steel coil, reducing the possibility of surface damage during the coiling process.

[0038] Reference Figure 1 and Figure 2 The movable frame 2 is also bolted with four telescopic cylinders 7 that are electrically connected to the control system. The four telescopic cylinders 7 are arranged in a rectangular shape and the piston rod of each telescopic cylinder 7 is threaded to the support frame 3.

[0039] Reference Figure 2 As the mobile frame 2 moves, the control system activates the telescopic cylinders 7. The piston rods of the four telescopic cylinders 7 extend upwards simultaneously, thereby lifting the steel coil on the support frame 3 to the upper coil height.

[0040] Once the steel coil is positioned on the unwinding device, the piston rod of the air telescopic cylinder 7 in the control system retracts downward, thereby creating a gap between the support frame 3 and the steel coil, which facilitates the resetting of the moving frame 2 and the support frame 3.

[0041] Reference Figure 2 A vertical lifting rod 10 is threadedly connected to the center of the bottom of the support frame 3. The lifting rod 10 slides into the movable frame 2. An X-shaped guide frame 9 is slidably sleeved on the lifting rod 10. Each apex of the guide frame 9 corresponds to a telescopic cylinder 7 and is slidably sleeved on the corresponding telescopic cylinder 7.

[0042] Reference Figure 2The lifting rod 10 is also fitted with two compression springs 11. One compression spring 11 is located above the guide frame 9 and supports the guide frame 9 and the support frame 3. The other compression spring 11 is located below the guide frame 9 and supports the guide frame 9 and the moving frame 2.

[0043] Reference Figure 2 During the extension and retraction of the piston rod of the telescopic cylinder 7, the two compression springs 11 work together to drive the guide frame 9 to rise and fall. The guide frame 9 plays a role in tensioning and linkage of the piston rods of each telescopic cylinder 7. Even if the steel coil is placed on the support frame 3 with a side deviation, the support frame 3 can stably support the steel coil.

[0044] The implementation principle of the auxiliary coiling device for steel strip in heat sink fin production according to the present application embodiment is as follows: the worker places the steel coil on the support frame 3 with the help of the handling tool, and then the control system starts the motor 6 and the telescopic cylinder 7. The output shaft of the motor 6 drives the roller 5 to roll on the track 4, and then the moving frame 2 moves the steel coil closer to the unwinding device. At the same time, the piston rod of the telescopic cylinder 7 extends upward, so that the support frame 3 lifts the steel coil to the coiling height. After the steel coil is installed on the unwinding device, the moving frame 2 and the support frame 3 are reset.

[0045] 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.
