Description

Technical Field

[0001] This utility model relates to the field of adhesive film processing technology, and in particular to a tension adjustment device for high-speed slitting of adhesive film. Background Technology

[0002] In the manufacturing process of computer electronic components, adhesive film is used as an auxiliary material. Its slitting process requires the use of a special tension adjustment device. This tension adjustment device consists of a tension sensor and an adjustment mechanism. It can monitor the tension changes of the adhesive film during the slitting process and dynamically adjust the tension mechanically to ensure the slitting quality of the adhesive film. In the production of computer electronic components, the adhesive film tension adjustment device can precisely control the tension of the adhesive film during high-speed slitting, avoiding excessive tension that causes the adhesive film to stretch and deform, resulting in adhesive layer detachment, and insufficient tension that causes the adhesive film to loosen and wrinkle. This ensures the dimensional accuracy and appearance quality of the adhesive film after slitting, improves the continuity and stability of the slitting process, and provides adhesive film material for subsequent assembly and bonding processes of computer electronic components.

[0003] Currently, the slitting efficiency of adhesive film tension adjustment devices on the market is low, and the slitting structure design is relatively simple, equipped with only one slitting slot. As a result, the device can only slit one sheet of adhesive film at a time during operation. After completing one slitting task, it will proceed to the next one. It cannot achieve high-efficiency slitting of adhesive film. In large-scale production scenarios, this single slitting slot restricts the production speed and makes it difficult to meet the demand of modern production lines for high-efficiency slitting.

[0007] As a further description of the above technical solution: The support assembly includes a support frame, the bottom of which is fixedly connected to the top of the upper support plate, and the top of which is fixedly connected to a frame slot.

[0008] As a further description of the above technical solution: The fixing assembly includes a component fixing bracket, the bottom of which is fixedly connected to the top of the bracket slot, and the top of the component fixing bracket has multiple fixing slots.

[0009] As a further description of the above technical solution: The sliding assembly includes a pulley, the outer wall of which is slidably connected to the upper side of the outer frame, and a side connecting column is rotatably connected to the right side of the pulley.

The pulley structure can ensure that the cutter runs smoothly during the slitting process, reducing the impact of mechanical vibration on the slitting accuracy. The driving force provided by the hydraulic rod can accurately control the cutting depth and speed of the cutter, adapting to the slitting requirements of adhesive films of different thicknesses, thereby improving slitting efficiency, shortening the slitting cycle per unit time, significantly improving overall production efficiency, and better meeting the batch processing needs of modern high-speed production lines.

Before slitting, the clamping plate can apply appropriate pressure to the adhesive film, allowing it to stretch naturally under tension, ensuring that the film surface is flat and wrinkle-free. The buffering effect of the elastic material can avoid the stretching deformation of the adhesive film substrate caused by rigid clamping, protect the structural integrity of the adhesive film, avoid damage to the material caused by improper clamping, and improve the qualification rate of the slitting product.

A clamping force adjustment component 47 is provided on the top of the clamping piece 46. The electronic components to be slit are introduced into the tension adjustment mechanism 4 using adhesive film. The clamping force adjustment component 47 adjusts the clamping force of the clamping plate 46 on the adhesive film, which in turn drives the internal hydraulic rod 44 to move the side connecting rod 45. This allows the clamping plate 46 to apply appropriate tension to the adhesive film, ensuring that the adhesive film is in a stable tension state before entering the high-speed slitting mechanism 3. Subsequently, the tension-adjusted adhesive film is conveyed to the support component 34 of the high-speed slitting mechanism 3.

The hydraulic push rod 311 pushes the slitting component 312, and with the extension and retraction of the upper and lower hydraulic rods 3122, the slitting blade 3123 performs the slitting operation on the adhesive film. During the slitting process, multiple fixing slots 352 can simultaneously position the adhesive film at different positions, realizing multi-position simultaneous slitting and improving slitting efficiency. After slitting, the adhesive film is output from the device. Throughout the slitting process, the bottom connecting block 5, sliding connecting column 6, and anti-slip base 7 at the bottom of the base plate 1 ensure the stable operation of the device and avoid the impact of vibration on the slitting accuracy. The tension adjustment mechanism 4 uses an internal hydraulic rod 44 to drive the movement of the side connecting rod 45 and the clamping piece 46. Combined with the adjustment of the clamping force adjustment component 47, precise control of the adhesive film tension is achieved, ensuring that the adhesive film is in the optimal tension state before slitting. The sliding component 38 in the high-speed slitting mechanism 3 drives the movement of the main frame 39 and the slitting component 312. With the drive of the hydraulic push rod 311 and the upper and lower hydraulic rods 3122, the slitting blade 3123 can quickly and accurately slit the adhesive film. The setting of multiple fixed slots 352 enables simultaneous slitting at multiple positions. This achieves efficient and precise slitting of the adhesive film, improves slitting efficiency and slitting quality, and meets the high precision and high efficiency requirements for adhesive film slitting in electronic component production.
