Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforcing sheet assembly technology, specifically a reinforcing sheet assembly structure. Background Technology
[0002] Reinforcing plates, also known as stiffeners, reinforcement plates, support plates, and reinforcing ribs, are mainly used in construction, oil pipelines, machinery and equipment, and electronic products. They are widely used in flexible printed circuit boards (FPCs) in electronic products. Reinforcing plates primarily address the flexibility of flexible circuit boards, improve the strength of connection points, and facilitate overall product assembly. Currently, when installing flexible circuit boards for mobile phones, reinforcing plates are attached to the more flexible areas to increase the strength of the connection points. However, existing technologies typically involve manual assembly followed by hot pressing for fixation, which is inefficient under high-volume workloads. Based on the shortcomings of existing technologies, this invention designs a reinforcing plate assembly structure. Utility Model Content

[0010] As a preferred embodiment of this utility model, the length of the flexible pressure roller is the same as the inner wall length of the assembly table, and the flexible pressure roller is made of flexible silicone.
[0011] As a preferred embodiment of this utility model, the outer surface of the flexible pressure roller is covered with double-sided adhesive tape, which can be peeled off and replaced.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This reinforcing sheet assembly structure, through a hot-pressing structure and a venting plate, allows workers to place one or more flexible circuit boards on the venting plate, attach the reinforcing sheet to the pre-drilled position on the circuit board, and then cover the assembly table with a cover plate. At this time, pressing down on the pressure handle causes four connecting rods to drive four pressure columns to press down on the springs. The four pressure rods then drive the hot-pressing plate to press down and contact the flexible circuit board. After a certain period of time, the reinforcing sheet is fixed on the flexible circuit board. At this time, the pressure handle can be released, the springs release their force and spring back, causing the hot-pressing plate to return to its original position. This allows for the assembly of multiple reinforcing sheets at a time, thereby improving production efficiency.
[0014] 2. This reinforcing sheet assembly structure, after the reinforcing sheet is assembled by a rolling structure and a hot pressing structure, the cover plate is folded over, and then the rotating rod is turned to flip it into the assembly table. At this time, the push rod is pushed to make the sliding rod slide in the slide rail. At this time, the flexible pressure roller rolls over the surface of the flexible circuit board, which reinforces the reinforcing sheet assembled on its surface. At the same time, the double-sided adhesive on the outer surface of the flexible pressure roller can remove dust from the flexible circuit board. Attached Figure Description

The hot pressing structure 4 includes two hinged seats 41, a cover plate 42 hinged inside the two hinged seats 41, four circular grooves 43 on the top of the cover plate 42, sleeves 44 installed inside the four circular grooves 43, abutment plates 45 installed at the bottom of the inner cavity of the four sleeves 44, springs 46 installed on the top of the four abutment plates 45, pressure columns 47 installed on the top of the four springs 46, pressure rods 48 installed at the bottom of the four pressure columns 47, a hot pressing plate 49 installed at the bottom of the four pressure rods 48, a connecting rod 410 installed on one side of the top of the four pressure columns 47, a center plate 411 installed between the four connecting rods 410, and a pressure handle 412 installed on the top of the center plate 411.
[0023] Please see Figure 2 The ventilation plate 6 is connected to the hot pressing structure 4, and an air vent 7 is provided on one side of the outer surface of the assembly table 2.
[0024] By connecting the air inlet 7 to the air pump, the air pump can be activated when the flexible circuit board is placed on the ventilation plate 6, thereby removing dust from both sides of the flexible circuit board and facilitating the subsequent assembly of the reinforcing plate.
[0025] Please see Figure 1-3A slide rail 8 is provided on one side of the top of the base 1, and a rolling structure 5 is provided inside the slide rail 8. The rolling structure 5 includes a sliding rod 51, which is slidably connected to the slide rail 8. A push rod 54 is installed on the top of the sliding rod 51, and the height of the push rod 54 is the same as the height of the sliding rod 51. A rotating rod 52 is rotatably installed on one side of the outer surface of the sliding rod 51, and a flexible pressure roller 53 is rotatably installed at one end of the rotating rod 52. The length of the flexible pressure roller 53 is the same as the length of the inner wall of the assembly table 2, and the flexible pressure roller 53 is made of flexible silicone. The outer surface of the flexible pressure roller 53 is covered with double-sided tape, which can be peeled off and replaced.
[0026] After the reinforcing sheets are assembled by the hot pressing structure 4, the cover plate 42 is folded over. Then, the rotating rod 52 is turned to flip it into the assembly table 2. At this time, the push rod 54 is pushed to make the sliding rod 51 slide in the slide rail 8. At this time, the flexible pressure roller 53 rolls over the surface of the flexible circuit board, which reinforces the reinforcing sheets assembled on the surface. At the same time, the double-sided adhesive on the outer surface of the flexible pressure roller 53 can remove dust from the flexible circuit board.
[0027] Working principle: When a reinforcing plate assembly structure is used, in the initial state, firstly, one or more flexible circuit boards are placed on the vent plate 6. Then, by connecting the air port 7 to the air pump, the air pump can be started when the flexible circuit board is placed on the vent plate 6, thereby cleaning the dust on both sides of the flexible circuit board, facilitating the subsequent assembly of the reinforcing plate. Then, after the reinforcing plate is attached to the reserved position on the circuit board, the cover plate 42 is placed on the assembly table 2. At this time, by pressing down the handle 412, the four connecting rods 410 drive the four pressure columns 47 to press down the spring 46. Four pressure rods 48 drive the hot press plate 49 to press down and contact the flexible circuit board. After a certain period of time, the reinforcing piece is fixed on the flexible circuit board. At this time, the pressure handle 412 can be released, the spring 46 releases the force and pops open, driving the hot press plate 49 to reset. After opening the cover plate 42, the rotating rod 52 is turned to flip it into the assembly table 2. At this time, the push rod 54 is pushed to make the sliding rod 51 slide in the slide rail 8. At this time, the flexible pressure roller 53 rolls over the surface of the flexible circuit board, which reinforces the reinforcing piece assembled on its surface. At the same time, the double-sided tape on the outer surface of the flexible pressure roller 53 can remove dust from the flexible circuit board.
