Description

Technical Field

[0001] This utility model belongs to the field of circuit board gold finger film application technology, specifically a PCB circuit board gold finger film cutting mechanism. Background Technology

[0002] The PCB circuit board gold finger film cutting mechanism is a device used to precisely cut the gold finger film during the PCB circuit board production process. The film treatment of the gold finger area is a key step in the PCB circuit board manufacturing process.

[0003] In existing PCB circuit board gold finger film-cutting mechanisms, gold fingers on a tray are transported to the film-applying assembly via guide wheels. A cutting mechanism then cuts a small section of adhesive tape from the tray for bonding to the gold fingers. However, existing film-cutting mechanisms typically use a blade to cut the tape. After prolonged use, the blade's opening becomes dull, leading to uneven cuts, burrs, or torn edges. This results in the gold fingers not being completely covered by the tape, causing contamination during subsequent circuit board processing. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 6 As shown, this is the first embodiment of the utility model, which provides a PCB circuit board gold finger film application and cutting mechanism, including a moving component 1, a feeding structure 2 disposed on the outside of the moving component 1, a film application component 3 disposed on the outside of the moving component 1 below the feeding structure 2, and a cutting mechanism 4 disposed on the outside of the moving component 1 outside the film application component 3.

[0026] The film application component 3 includes a connecting block 301, a guide wheel 304, and a cylinder 309. The bottom of the connecting block 301 is hinged to a cylinder 302. The bottom of the cylinder 302 is provided with an adhesive wheel 303. The outer side of the guide wheel 304 is connected to the outer wall of the moving component 1 and is located to the right of the adhesive wheel 303. The bottom of the cylinder 309 is provided with a pressure wheel 310, which is located to the left of the adhesive wheel 303.

[0027] The cutting mechanism 4 includes a mounting block 401. The outer side of the mounting block 401 is connected to the inner wall of the moving component 1. A cylinder 402 is provided at the bottom of the mounting block 401. A movable block 403 is provided on the outer side of the cylinder 402. A pneumatic scissor 404 is provided at the bottom of the movable block 403. The pneumatic scissor 404 is located behind the adhesive roller 303 and the pressure roller 310.

[0028] When the film application assembly 3 is running, the guide wheel 304 guides the gold fingers on the feeding structure 2, feeding them to the bottom of the pressure roller 310 and the adhesive roller 303. The pressure roller 310 and the adhesive roller 303 then squeeze the tape, pressing one end of the tape onto the circuit board. The pressure roller 310 adheres the tape to the gold fingers. After the gold fingers on the circuit board are filmed, the cylinder 402 is activated, moving the movable block 403 and the pneumatic scissors 404 forward. The pneumatic scissors 404 then move between the adhesive roller 303 and the pressure roller 310, cutting the attached tape. The pneumatic scissors 404 cut the tape by interlocking two blades, providing a more uniform shearing force and resulting in a smoother cut. This prevents uneven cuts, burrs, or torn tape edges, thus avoiding problems that could affect the quality of the gold finger film application.

[0029] Example 2

[0030] like Figures 3 to 5 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the moving component 1 includes a support frame 101, a connecting frame 102 is provided on the outside of the support frame 101, a driving structure 103 is provided on the outside of the connecting frame 102, a movable plate 104 is connected to the outside of the driving structure 103, and the inner side of the movable plate 104 is movably connected to the outer surface of the support frame 101.

[0031] By activating the drive structure 103, the movable plate 104 is moved on the outer surface of the support frame 101, and the movable plate 104 moves the film application assembly 3 and the cutting mechanism 4, making it easier to apply film to the gold fingers on the circuit board.

[0032] Among them, the feeding structure 2 includes a bearing 201, the outer side of the bearing 201 is connected to the outer side of the movable plate 104, and a material tray 202 is provided on the outer surface of the bearing 201.

[0033] The adhesive roller 303 presses down, causing the bottom of the tape to adhere to the gold finger. Then, as the movable plate 104 moves, it pulls the tape, causing the material tray 202 to rotate on the bearing 201. Finally, the pressure roller 310 firmly adheres the tape to the gold finger.

[0034] Among them, a stop block is provided on the outside of the material tray 202, and the stop block is fixed on the material tray 202 by bolts;

[0035] By removing the bolts from the reel 202, the obstruction to the tape roll is removed, making it easier to secure the tape roll and thus easier to replace it.

[0036] Among them, the outer side of the guide wheel 304 is connected to the outer wall of the movable plate 104, the guide wheel 304 is hinged to the shaft end of the shaft end of the shaft end of the shaft end of the guide wheel 304, the other end of the base 305 is hinged to the shaft end of the adhesive wheel 303, and the bottom of the base 305 is provided with a guard plate 306.

[0037] By guiding the tape on the outside of the guide wheel 304 between the base 305 and the guard plate 306, the bottom is protected by the guard plate 306 to prevent the tape from being affected by the outside. The operation of the cylinder 302 drives the tape on the outer surface of the adhesive wheel 303 to adhere to the gold finger.

[0038] Among them, a second cylinder 307 is provided on the top of the base 305, and a pressure block 308 located in the inner cavity of the base 305 is provided at the bottom of the second cylinder 307.

[0039] Before cutting the tape, cylinder 2 307 is activated, which drives the pressure block 308 to squeeze the tape conveyed between the adhesive roller 303 and the guide roller 304, so that the tape is fixed in the inner cavity of the base 305. This prevents the tape from moving when cutting the tape, which would cause the tape to be unable to stay taut and prevent wrinkles from appearing on the tape during subsequent film application.

[0040] Among them, the base 305 is movably connected to the limiting block 311, and the top of the base 305 is provided with a pressing block 312. The pressing block 312 is fixed on the base 305 by screws, and the bottom of the pressing block 312 is movably connected to the top of the limiting block 311.

[0041] By rotating the screws, the clamping block 312 is released from its fixation, and the limiting block 311 is released from its fixation. Then, the scale on the outside of the base 305 is used to adjust the distance between the limiting block 311 and the base 305 so that it is the same as the width of the tape. This is used to limit the conveyed tape and prevent the tape from shifting to the left or right, thus avoiding positional deviation when applying the film.

[0042] Working principle and usage process of this utility model:

[0043] First, when the operator is applying film to the gold fingers of the circuit board, the drive mechanism 103 is activated, moving the movable plate 104 to the position where the film needs to be applied. Then, cylinder 302 is activated, causing the adhesive tape at the bottom of the adhesive roller 303 to adhere to the gold fingers. The drive mechanism 103 then moves the movable plate 104. Since one side of the tape is adhered to the gold fingers, the movement of the movable plate 104 pulls the tape on the tray 202. As the tape moves below the pressure roller 310, cylinder 309 is activated, causing the pressure roller 310 to squeeze the tape, further firmly adhering it to the gold fingers. Once the film application is complete... Then, cylinder 307 is activated, which drives the pressure block 308 to squeeze the tape on the guard plate 306. At the same time, cylinder 402 is activated, which drives the movable block 403 and the pneumatic scissors 404 to move. This causes the pneumatic scissors 404 to move between the adhesive roller 303 and the pressure roller 310. The tape is then cut by the operation of the pneumatic scissors 404. The tape is cut by the biting of the two blades of the pneumatic scissors 404, which provides uniform shearing force and makes the cut of the tape relatively flat and smooth. It is less likely to have uneven cuts, burrs, or torn tape edges, thus preventing protective omissions and avoiding contamination of the gold fingers during subsequent processing.
