Description

Technical Field

[0001] This utility model relates to the field of circuit board patch adhesive cutting technology, and in particular to a flexible printed circuit board patch adhesive cutting device. Background Technology

[0002] FPCB stands for Flexible Printed Circuit Board. During the manufacturing process of FPCBs, a large amount of double-sided adhesive tape (surface mount adhesive) is used to attach and fix chips. The shape of this double-sided adhesive tape generally depends on the shape of the electronic component being attached.

[0003] The adhesive used for PCB mounting requires cutting. Existing technology, disclosed in CN222661880U, describes a cutting device for flexible printed circuit board adhesive. However, this prior art is inefficient because it uses a single cutter to cut the adhesive, while flexible printed circuit boards consist of multiple adhesive pieces requiring fixed dimensions. Therefore, this application proposes a cutting device for flexible printed circuit board adhesive. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5 As shown, this utility model embodiment proposes a flexible printed circuit board (PCB) patch adhesive cutting device, comprising:

[0023] The support frame 1, serving as the fundamental support structure for the entire device, is made of high-strength metal materials, such as aluminum alloy, to ensure the stability and durability of the device. A mounting plate 2 is installed on the support frame 1, and the mounting plate 2 is securely connected to the support frame 1 by bolts to ensure that no shaking occurs during the cutting process.

[0024] A guide groove 14 is provided through the mounting plate 2. The dimensions of the guide groove 14 are precisely designed to ensure that the T-block 15 can slide smoothly within it. A clearance fit is used between the T-block 15 and the guide groove 14, with the clearance controlled within a reasonable range to ensure flexible movement of the T-block 15 while preventing wobbling due to excessive clearance. A second electric push rod 13 is installed at the bottom of the bracket 1. The second electric push rod 13 is a model with high-precision control function (specific models are available on the market), and its output end is fixedly connected to the T-block 15. Through the extension and retraction of the second electric push rod 13, the position of the T-block 15 within the guide groove 14 can be precisely controlled, thereby achieving accurate horizontal positioning of the cutting plate 8.

[0025] The upper end of the T-block 15 is provided with a slot 16. The depth and width of the slot 16 are designed according to the size of the insert 17 to ensure that the insert 17 can be tightly inserted into the slot 16. The insert 17 is slidably connected in the slot 16. A cutting plate 8 is fixed to the upper end of the insert 17. The cutting plate 8 is made of wear-resistant and high-hardness plastic material to ensure that it will not be worn by the cutter 10 during long-term use. The upper end of the cutting plate 8 is provided with multiple grooves 9. Fixed blades that cooperate with the cutter 10 are installed in the grooves 9. When the cutter 10 abuts against the fixed blades, it can cut the adhesive.

[0026] A guide rail 18 is mounted on the upper end of the mounting plate 2. The guide rail 18 is a linear guide rail, characterized by high precision and low friction. A slide plate 19 is slidably connected inside the guide rail 18, and the slide plate 19 is fixedly connected to the bottom of the cutting plate 8. The thickness of the slide plate 19 is equal to or greater than the thickness of the insert block 17. This design allows the slide plate 19 to act as a support, facilitating the stacking and storage of the slide plate 19 and its stable placement on other workbenches.

[0027] The cutting assembly includes a mounting bracket 3 fixed to the upper end of the support 1. The mounting bracket 3 has a rigid structure to withstand the reaction force during the cutting process. A first electric push rod 4 is mounted on the mounting bracket 3. The first electric push rod 4 is a high-torque, high-precision model that can provide sufficient cutting force. A movable plate 7 is fixed to the output end of the first electric push rod 4. The movable plate 7 moves up and down through the telescopic movement of the first electric push rod 4.

[0028] To ensure the stability of the moving plate 7 during its vertical movement, two guide sleeves 6 are installed through the mounting frame 3. The guide sleeves 6 are made of wear-resistant materials, such as bronze. A guide rod 5 is slidably connected inside the guide sleeve 6, and the guide rod 5 is fixedly connected to the upper end of the moving plate 7. The small clearance between the guide rod 5 and the guide sleeve 6 effectively restricts the movement direction of the moving plate 7, preventing it from shifting during movement and thus improving cutting accuracy.

[0029] The upper end of the movable plate 7 is connected to a connecting plate by bolts. The connecting plate is fixedly connected to the output end of the first electric push rod 4 and the guide rod 5, which facilitates the replacement of the movable plate 7 and the bottom components as a whole, so as to cut different sizes of adhesive patches.

[0030] Multiple cutters 10, which mate with the cutting groove 9, are mounted on the bottom of the movable plate 7. The cutters 10 are made of a high-hardness, high-wear-resistant material, such as high-speed steel. The blades of the cutters 10 are finely ground, providing sharp cutting edges for fast and accurate cutting of the adhesive patch. The cutters 10 are bolted to the bottom of the movable plate 7 for easy replacement.

[0031] The number and spacing of the cutters 10 correspond to the grooves 9 on the cutting plate 8, ensuring that each cutter 10 can accurately fall into the corresponding groove 9 during the cutting process, thereby enabling the cutting of multiple adhesive patches at one time and greatly improving cutting efficiency.

[0032] To prevent the flexible printed circuit board from moving during the cutting process and affecting cutting accuracy, this device also includes clamping components. There are two sets of clamping components distributed on both sides of the cutter 10. Each set includes two telescopic elastic elements 11 fixed to the bottom of the moving plate 7. The telescopic elastic elements 11 are made of springs, sleeves, and short tubes, with the short tubes and springs inside the sleeves. The springs are fixedly connected to the sleeves and short tubes. The telescopic elastic elements 11 ensure clamping force while preventing damage to the flexible printed circuit board. A pressure plate 12 is fixed to the bottom of the two telescopic elastic elements 11. The pressure plate 12 is made of a soft, elastic material, such as rubber, to increase the contact area with the flexible printed circuit board and improve the clamping effect.

[0033] During the cutting process, when the moving plate 7 moves downward, the pressure plate 12 first contacts the flexible printed circuit board and presses it firmly and fixes it. Then the cutter 10 continues to move downward to cut, ensuring the stability of the cutting process.

[0034] When using this device to cut the adhesive on flexible printed circuit boards (PCBs), first, place the PCB on the cutting plate 8 and adjust its position. Then, activate the second electric push rod 13. According to the cutting position requirements of the adhesive, control the movement of the T-block 15 within the guide groove 14 to move the cutting plate 8 to a suitable horizontal position. Next, activate the first electric push rod 4. The first electric push rod 4 drives the moving plate 7 downward. During the movement, the pressure plate 12 first contacts the PCB and presses it firmly. As the moving plate 7 continues to move downward, the cutter 10 falls into the cutting groove 9 on the cutting plate 8, completing the cutting of the adhesive. After cutting, the first electric push rod 4 drives the moving plate 7 upward, while the second electric push rod 13 can adjust the position of the cutting plate 8 as needed.

[0035] The worker can move the cutting plate 8 up to remove it and the cutting plate 8 after the surface is cut, and then place another cutting plate 8 with adhesive on the T-block 15; repeat the above operation to cut; the worker removes and stores the cut adhesive and cleans the cutting plate 8 to avoid inconvenience to the next cut; in this way, the storage of adhesive and the cleaning of the cutting plate 8 will not affect the cutting work, greatly improving work efficiency.

[0036] The cutting plate 8 can also be replaced to accommodate different sizes of adhesive patches.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
