Description

Technical Field

[0001] The utility model relates to the field of adhesive tape slitting, in particular to a polyimide adhesive tape slitting device. Background Art

[0002] Polyimide tapes are based on polyimide film and are often made with imported silicone pressure-sensitive adhesives. Some products also use crosslinking agents such as benzoyl peroxide to further enhance heat resistance. While tapes are typically produced in large rolls, practical applications often require tapes of varying lengths and widths to meet various packaging and bonding requirements. Therefore, they must be slit to obtain tape segments that meet specific requirements.

[0003] After searching, in the prior art, the Chinese patent with patent announcement number CN221521557U discloses "a tape slitting device, relating to the field of tape processing technology, including a tape unwinding roller, a support hanger and a cutter assembly, the cutter assembly including a rotating shaft, a plurality of tape cutters detachably mounted on the rotating shaft and a drive shaft fixedly mounted at one end of the rotating shaft, a lifting module is provided on the support hanger, and a detachably connected assembly part is also provided on the support hanger, a plurality of sliding fixing parts are detachably connected to the assembly part, and each sliding fixing part is provided with a glue removal structure for removing glue from the tape cutter, the moisture-absorbing wiping cotton block of this utility model acts on the radius of the tape cutter in a manner of being soaked with a cleaning glue remover, and the rotating motion of the tape cutter is in friction contact with the moisture-absorbing wiping cotton block, which can effectively clean the adhesive remaining on the tape blade due to the slitting blade, thereby ensuring the reliability of the subsequent slitting of the tape blade", but the following defects still exist:

[0004] (1) However, when the device is slitting the tape, it lacks a device that can support the tape unwinding roller, and also lacks a device that drives the tape unwinding roller to rotate. Therefore, when the tape is slitting, only part of the tape roll can be cut, and the slitting effect is poor.

[0005] (2) However, the device lacks the ability to guide the debris generated when the tape is cut. When some debris is cut off, the debris may adhere to the tape roll after cutting, thereby affecting the cleanliness of the product.

[0006] Therefore, we make improvements to this and propose a polyimide tape slitting device. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] like Figure 1-6 As shown, this embodiment provides a polyimide tape slitting device, comprising a workbench 1, a slitting mechanism 2 for slitting the tape is provided on the top of the workbench 1, and a guide component 3 for guiding debris generated during slitting is provided on the top of the workbench 1;

[0036] The slitting mechanism 2 includes a first motor 201, a rotating rod 202, an electric telescopic rod 203, a frame 204, a connecting rod 205, a blade 206 and a second motor 207. The first motor 201 is bolted to the side wall of the workbench 1, the rotating rod 202 is coaxially arranged at the output end of the first motor 201, the electric telescopic rod 203 is bolted to the side wall of the workbench 1, the frame 204 is fixedly connected to the output end of the electric telescopic rod 203, the connecting rod 205 is rotatably connected to the inside of the frame 204, the blade 206 is fixedly connected to the outer wall of the connecting rod 205 and is evenly distributed along the length direction of the connecting rod 205, the second motor 207 is bolted to the side wall of the frame 204, and the first motor 201 drives the rotating The rod 202 rotates, and the second motor 207 drives the connecting rod 205 to rotate. There are several protrusions evenly distributed on the surface of the rotating rod 202 along the length direction. The protrusions can help the tape roll sleeve resist the sliding tendency and improve the stability of the transmission. When in use, the first motor 201, the second motor 207 and the electric telescopic rod 203 are connected to the external power supply, and then the tape roll to be cut is placed on the rotating rod 202, and then the first motor 201 is started to make the tape roll rotate along with the rotating rod 202, and then the second motor 207 is started to make the blade 206 rotate along with the connecting rod 205. At this time, the electric telescopic rod 203 drives the frame 204 to move, and then the blade 206 contacts the tape roll, thereby cutting.

[0037] like Figure 3 As shown, the guide assembly 3 includes an air inlet groove 301, an exhaust pipe 302 and an exhaust fan 303. The air inlet groove 301 is opened at the top of the workbench 1, and the exhaust pipe 302 is connected to the bottom of the air inlet groove 301. The exhaust fan 303 is bolted to one end of the exhaust pipe 302. When the tape roll is cut, debris may be generated. At this time, the exhaust fan 303 is connected to an external power supply, and then the exhaust fan 303 is started. The exhaust fan 303 puts the air inlet groove 301 in a negative pressure state. Through the action of atmospheric pressure, the debris will enter the air inlet groove 301, thereby preventing the debris from floating around and causing the debris to adhere to the cut tape roll.

[0038] like Figure 5 As shown, a slide groove 4 is provided on the top of the workbench 1, and a slide plate 5 is slidably connected inside the slide groove 4. A support plate 6 is welded on the top of the slide plate 5. One end of the rotating rod 202 passes through the slide plate 5 and is rotatably connected to the slide plate 5. When in use, the support plate 6 and the slide plate 5 slide inside the slide groove 4, so that one end of the rotating rod 202 is fixed, thereby improving the stability when slitting the tape roll.

[0039] like Figure 5As shown, a rectangular frame 7 is bolted to the side wall of the workbench 1, and the internal sliding connection of the rectangular frame 7 is a limit block 8. A slide rod 9 is welded on the side wall of the limit block 8, and a spring 10 is sleeved on the outside of the slide rod 9. A positioning block 11 is welded at one end of the spring 10. The side wall of the positioning block 11 is bolted to the side wall of the workbench 1, and the side wall of the limit block 8 fits tightly with the side wall of the slide plate 5. When the support plate 6 is used to improve the stability of the rotating rod 202, the limit block 8 will limit one end of the slide plate 5. When the next roll of tape to be cut needs to be cut, the slide rod 9 is pulled to contract the spring 10, and then the limit block 8 is released from the restriction on the slide plate 5, and then the support plate 6 is removed, so that the next roll of tape to be cut can be installed.

[0040] like Figure 2 and Figure 3 As shown, a scraper 12 is bolted to the side wall of the frame 204, and a collecting frame 13 is bolted to the top of the workbench 1. The side wall of the scraper 12 fits tightly with the side wall of the blade 206, and the collecting frame 13 is located below the scraper 12. When in use, the scraper 12 can effectively scrape off the glue on the blade 206, thereby slowing down the speed at which the blade 206 becomes stiff. When the cutting is completed, the worker can completely clean the blade 206 through external equipment.

[0041] like Figure 1 As shown, an isolation net 14 is bolted inside the air inlet groove 301, and the outer walls of the isolation net 14 are tightly fitted with the inner walls of the air inlet groove 301. When in use, the isolation net 14 can prevent debris from directly entering the exhaust pipe 302 and causing the exhaust pipe 302 to be blocked.

[0042] like Figure 6 As shown, the bottom of the frame 204 is bolted with an extension block 15, and the top of the workbench 1 is bolted with a slide rail 16. The extension block 15 is located inside the slide rail 16 and is slidably connected to the slide rail 16. When the frame 204 moves, the bottom of the frame 204 is supported by the extension block 15 and the slide rail 16, thereby improving the accuracy of the movement of the frame 204.

[0043] Specifically, when the polyimide tape slitting device is in use: the first motor 201, the second motor 207, the electric telescopic rod 203 and the exhaust fan 303 are connected to the external power supply, and then the tape roll to be slit is placed on the rotating rod 202, and then the slide plate 5 is slid inside the slide groove 4. When one end of the slide plate 5 contacts one end of the slide groove 4, the spring 10 drives the limit block 8 to reset, so that one end of the slide plate 5 is supported. At this time, one end of the rotating rod 202 will be inserted into the support plate 6, thereby fixing one end of the rotating rod 202. Then, the first motor 201 is started to make the tape roll rotate with the rotating rod 202, and then the second motor 207 is started to make the blade 206 rotate with the connecting rod 205. At this time, the electric telescopic rod 201 is turned on and the tape roll rotates with the rotating rod 202. 03 drives the frame 204 to move, so that the blade 206 contacts the tape roll, thereby cutting. When cutting the tape roll, debris may be generated. At this time, the exhaust fan 303 is connected to the external power supply, and then the exhaust fan 303 is started. The exhaust fan 303 puts the air inlet slot 301 in a negative pressure state. Through the action of atmospheric pressure, the debris will enter the air inlet slot 301. At this time, the isolation net 14 can prevent the debris from directly entering the exhaust pipe 302, causing the exhaust pipe 302 to be blocked. After the cutting is completed, the slide bar 9 is pulled when used to shrink the spring 10. At this time, the limit block 8 is separated from the slide plate 5, and then the support plate 6 is removed. Then the next tape roll to be cut is installed, and then the above steps are repeated to perform the next cutting.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
