Description

Technical Field

[0001] This utility model relates to the field of cutting mold technology, and in particular to an FPC adhesive cutting mold. Background Technology

[0002] FPC adhesive is made by coating one side of PET with black adhesive and the other side with white adhesive and curing it. After a series of treatments, it has good surface adhesion and light-blocking properties, and can be easily fixed to the device that needs to be shielded. It is widely used in many fields. When using FPC adhesive, it is necessary to use a cutting mold to cut it into different shapes and sizes for use on different items.

[0003] When cutting FPC adhesive backing, it is often necessary to cut it into different shapes and sizes, which requires changing the corresponding cutting mold. However, most current cutting molds are fixed to the cutting machine by welding or multiple screws, which makes it inconvenient to disassemble and replace them. Therefore, in order to solve the above defects, the inventor proposes an FPC adhesive backing cutting mold. Utility Model Content

[0004] The main purpose of this utility model is to provide an FPC adhesive cutting mold, which can effectively solve the problem that most existing FPC adhesive cutting molds are fixed to the cutting machine by welding or multiple screws, resulting in inconvenience in disassembly and replacement.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This utility model discloses an FPC adhesive-backed cutting mold, such as Figure 1-5 As shown, the cutting frame 1 includes an upper mold 5 and a lower mold 4 located inside the cutting frame 1 for cutting FPC backing adhesive. A lifting plate 2 is slidably connected to the outer surface of the cutting frame 1. The upper mold 5 is provided with the bottom surface of the lifting plate 2. The lower mold 4 is located on the inner bottom surface of the cutting frame 1, and the bottom surface of the lower mold 4 is provided with a base 401.

[0022] A cylinder 3 is fixedly installed on the outer top surface of the cutting frame 1, and the output end of the cylinder 3 is fixedly connected to the lifting plate 2. When the cylinder 3 pushes the lifting plate 2 to move up and down, it will drive the upper mold 5 to move up and down, so as to cut the FPC backing adhesive placed on the top surface of the lower mold 4.

[0023] An installation sleeve 201 is fixedly installed in the middle of the bottom surface of the lifting plate 2. A first spring 202 is fixedly installed on the inner top surface of the installation sleeve 201, and a movable plate 203 is fixedly installed on the bottom surface of the first spring 202. When the movable plate 203 rises, it will compress the first spring 202.

[0024] Two fixed plates 204 are slidably connected at the opening of the mounting sleeve 201. The two fixed plates 204 can slide left and right. Connecting arms 205 are hinged on both sides of the movable plate 203, and the two connecting arms 205 are respectively hinged to the two fixed plates 204. When the movable plate 203 rises, the two connecting arms 205 can push the two fixed plates 204 closer to each other. When the movable plate 203 falls, the two connecting arms 205 can push the two fixed plates 204 away from each other.

[0025] An installation block 501 is fixedly installed in the middle of the top surface of the upper mold 5, and a fixing groove 502 is opened on both the left and right sides of the outer surface of the installation block 501. A fixing rod 503 is fixedly installed on both sides of the top surface of the upper mold 5, and a limit plate 504 is rotatably connected to the top surface of the two fixing rods 503. Limit holes 206 are opened on both sides of the top surface of the lifting plate 2. The installation block 501 is inserted into the installation sleeve 201, and the movable plate 203 is pushed up to compress the first spring 202. When the movable plate 203 rises, the two connecting arms 205 can push the two fixing plates 204 closer to each other until they are inserted into the two fixing grooves 502. During this process, the two limit plates 504 will pass through the two limit holes 206. Then, the limit plates 504 are rotated so that they do not coincide with the limit holes 206, thus completing the installation of the upper mold 5.

[0026] The top surface of the base 401 has placement slots 407 on both the left and right sides. The interior of the placement slots 407 has telescopic holes 402 on both sides. A second spring 403 is fixedly installed on the opposite side of the two telescopic holes 402. A connecting block 405 is fixedly installed on the opposite end of the two second springs 403. A movable rod 404 is fixedly installed on one side of the two connecting blocks 405. When the movable rod 404 moves, it will drive the connecting block 405 to move.

[0027] Two movable rods 404 are respectively inserted inside two second springs 403. Parts of the two movable rods 404 are located inside two telescopic holes 402, and the other parts of the two movable rods 404 are located outside the two telescopic holes 402. Two connecting holes 406 are opened on both the left and right sides of the lower mold 4. Pulling the movable rods 404 outwards from the telescopic holes 402 will drive the connecting block 405 to move into the telescopic holes 402 and squeeze the second springs 403. Then, the two sides of the lower mold 4 are inserted into the two placement slots 407, and the movable rods 404 are released. The squeezed second springs 403 will push the connecting block 405 to reset and insert it into the connecting hole 406 to complete the installation of the lower mold 4.

[0028] A cutting blade assembly 4011 is fixedly installed in the middle of the bottom surface of the upper mold 5. Four positioning holes 5012 are opened in the bottom surface of the upper mold 5. A cutting blade hole assembly 5011 is opened in the middle of the top surface of the lower mold 4. Four positioning rods 4012 are fixedly installed in the top surface of the lower mold 4. The cutting blade assembly 4011 corresponds to the cutting blade hole assembly 5011.

[0029] The four positioning holes 5012 correspond one-to-one with the four positioning rods 4012, and the size of the four positioning holes 5012 is the same as the size of the four positioning rods 4012. The FPC adhesive is pre-drilled with four holes, and the four positioning rods 4012 pass through the four holes to fix the FPC adhesive and prevent the FPC adhesive from shifting during the cutting process.

[0030] A fixed frame 4021 is fixedly installed in the middle of the top surface of the base 401. A collection box 4023 is slidably connected inside the fixed frame 4021, and the collection box 4023 is located below the lower mold 4. A threaded rod 4022 is threadedly connected to the rear side of the outer surface of the fixed frame 4021. One end of the threaded rod 4022 located inside the fixed frame 4021 is rotatably connected to the collection box 4023. Rotating the threaded rod 4022 can push the collection box 4023 to move.

[0031] A handle is fixedly installed at one end of the threaded rod 4022 outside the fixed bracket 4021.

[0032] The working principle of this utility model is as follows: Four holes are pre-drilled in the FPC backing adhesive to be cut, and four positioning rods 4012 pass through the four holes to fix the FPC backing adhesive. The FPC backing adhesive to be cut is placed on the top surface of the lower mold 4. Then, the cylinder 3 pushes the lifting plate 2 and the upper mold 5 to descend to cut the FPC backing adhesive. The limiting plate 504 is rotated to coincide with the limiting hole 206. Then, the first spring 202, which is compressed, can push the movable plate 203 to descend. When the movable plate 203 descends, the two connecting arms 205 can push the two fixing plates 204 away from each other to be pulled out from the fixing groove 502. At the same time, the descent of the movable plate 203 can push the mounting block 501 out of the mounting sleeve 201 to disassemble the upper mold 5. The movable rod 404 is pulled towards the outside of the telescopic hole 402 to drive the connecting block 405 to squeeze the second spring 403 and move into the telescopic hole 402, so that the lower mold 4 can be disassembled. Then, the corresponding upper mold 5 and lower mold 4 can be replaced as needed.
