[0002] Specialized adhesive tapes used in the precision manufacturing of electronic components, semiconductors, and other electronic devices typically consist of a base film, an adhesive layer, and a protective layer. Drying the adhesive layer during production requires the use of a drying tunnel oven. The current drying tunnel oven design utilizes linear metal rollers to transport the film, which can easily scratch the back of the film from contact with the rollers. Due to the long length of the tunnel oven and the softness of the film, the film is prone to vibration during transport. Furthermore, the adhesive layer is susceptible to dust accumulation during the drying process. These issues severely impact the product's appearance and performance stability, making the current drying tunnel oven insufficiently suitable and requiring structural improvements.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The top of the base 1 is fixedly connected to the tunnel furnace frame 13. The left side of the tunnel furnace frame 13 is fixedly connected to a second fixed seat 26. Both sides of the tunnel furnace frame 13 are fixedly connected to a first fixed seat 2. The rear ends of the first and second fixed seats 26 are respectively fixedly connected to fixed blocks 20. The rear ends of one side of the first and second fixed seats 26 are fixedly connected to a hinged seat 23. The front and rear ends of the inside of the tunnel furnace frame 13 are fixedly connected to mounting seats 14. A driving shaft 15 is movably connected between the mounting seats 14.

[0024] The driving shaft 15 is made of a slightly sticky rubber roller and is arc-shaped and evenly spaced inside the tunnel furnace frame 13;

[0025] Specifically, if Figure 1 and Figure 2 As shown, since the material of the active shaft 15 is a micro-sticky rubber roller, the speed of the roller and the film material conveying are synchronized. The material of the micro-sticky rubber roller is soft and not easy to scratch the film material. The micro-sticky rubber roller can effectively stick to the dust on the bottom of the film material during operation, and can effectively reduce vibration under the micro-sticky effect. The design principle of the micro-sticky rubber roller mainly relies on the action and reaction force between molecules. This force enables the rubber roller to achieve the effect of sticking to dust through physical action without relying on its own viscosity.

[0026] Example 2: A guide groove 3 is provided inside the front end of the first fixing seat 2 and the second fixing seat 26. A reserved groove 6 is provided at the top of the guide groove 3. A cylinder 7 is fixedly installed inside the reserved groove 6. A telescopic rod 8 is fixedly connected to the bottom end of the cylinder 7.

[0027] The bottom end of the telescopic rod 8 passes through the top end of the guide groove 3 and is fixedly connected to the slider 5. The slider 5 is movably connected to the tension roller 4. The slider 5 is embedded in the guide groove 3 and can slide.

[0028] Specifically, if Figure 1 and Figure 4 As shown, since the micro-adhesive rollers of each section in the tunnel furnace frame 13 are arranged in an arc shape as a whole, the cylinder 7 is opened and the telescopic rod 8 is used to drive the slider 5 to move up and down in the guide groove 3, thereby adjusting the height of the tension roller 4, facilitating the adjustment of the tension, and ensuring balanced tension output of the film material.

[0029] Example 3: One side of the first fixing seat 2 is fixedly connected to the first connecting seat 9, one side of the second fixing seat 26 is fixedly connected to the second connecting seat 16, the front end of the second connecting seat 16 is fixedly mounted with the second motor 18, the output end of the second motor 18 is fixedly connected to the second connecting shaft 19, the front end of the first connecting seat 9 is fixedly connected to the first motor 11, the output end of the first motor 11 is fixedly connected to the first connecting shaft 12, the hinged seat 23 is movably hinged with a connecting sleeve 24, one side of the connecting sleeve 24 is fixedly connected to the third connecting seat 22, and the front end of the third connecting seat 22 is provided with a movable groove 25;

[0030] The outside of the first connecting shaft 12 is fixedly connected to the winding roller 10, and the outside of the second connecting shaft 19 is fixedly connected to the unwinding roller 17;

[0031] The first connecting shaft 12 and the second connecting shaft 19 are respectively embedded in the movable groove 25 and can rotate;

[0032] A buckle 21 is movably connected to one side of the front end of the third connecting seat 22, and the buckle 21 is detachably connected to the outside of the fixing block 20;

[0033] Specifically, if Figure 1 and Figure 3 As shown, when unloading, the buckle 21 can be flipped open from the fixed block 20, and the third connecting seat 22 can be opened by utilizing the movable hinge relationship between the hinge seat 23 and the connecting sleeve 24, so that the movable groove 25 can be disengaged from the first connecting shaft 12 and the second connecting shaft 19, thereby facilitating unloading and loading.

[0034] Working principle: When the present invention is in use, first of all, because the material of the active shaft 15 is a micro-sticky rubber roller, the speed of the roller and the film material conveying are synchronized. The material of the micro-sticky rubber roller is soft and not easy to scratch the film material. The micro-sticky rubber roller can effectively stick to the dust on the bottom of the film material during operation, and can also effectively reduce vibration under the micro-sticky effect. The design principle of the micro-sticky rubber roller mainly relies on the action and reaction force between molecules. This action force enables the rubber roller to achieve the dust-sticking effect through physical action without relying on its own viscosity. Because the micro-sticky rollers of each section in the tunnel furnace frame 13 are arranged in an arc shape as a whole, the cylinder 7 is opened and the telescopic rod 8 is used to drive the slider 5 to move up and down in the guide groove 3, thereby adjusting the height of the tension roller 4, facilitating the adjustment of the tension, and ensuring the balanced output of the film material tension. Finally, when unloading, the buckle 21 can be flipped open from the fixed block 20, and the third connecting seat 22 can be opened by utilizing the movable hinged relationship between the hinged seat 23 and the connecting sleeve 24, so that the movable groove 25 can be disengaged from the first connecting shaft 12 and the second connecting shaft 19, thereby facilitating unloading and loading.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
