Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, and more specifically, to a roll-type flexible circuit board. Background Technology

[0002] Flexible circuit boards, also known as "flexible boards," are printed circuits made of flexible insulating substrates. Flexible circuits offer excellent electrical performance, meet the design needs of smaller and higher-density installations, and help reduce assembly steps and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. They can be freely bent, rolled, and folded, and can withstand millions of dynamic bends without damaging the wires. They can be arranged arbitrarily according to spatial layout requirements and can move and stretch arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection. Flexible circuit boards can greatly reduce the size and weight of electronic products, and are suitable for the development of electronic products towards high density, miniaturization, and high reliability.

[0003] A search revealed that Chinese Patent (Announcement No.: CN221634009U) discloses "a roll-type flexible circuit board, including a roll shell, circular plates on both sides of the roll shell, the circular plates being fixedly connected to the roll shell, a limiting rod inside the circular plate, a pressure plate on the surface of the limiting rod, the pressure plate being fixedly connected to the limiting rod, a compression spring on the surface of the limiting rod, the compression spring being between the pressure plate and the circular plate, a limiting block on one side of the limiting rod, the limiting block being fixedly connected to the limiting rod, a fixing buckle on the surface of the limiting rod, the fixing buckle being detachably connected to the limiting rod, a fixing block on one end of the limiting rod, the fixing block being fixedly connected to the limiting rod, and an outlet on one side of the roll shell";

[0004] However, in the process of implementing the relevant technology, the above-mentioned patent has certain technical defects. Specifically, the patent achieves the function of fixing the roll-type flexible circuit board during use and recycling by setting a circular plate, a limiting rod, a pressure plate, a compression spring, a limiting circular block, a fixing buckle, a fixing block, a limiting ring, and a limiting hole. However, when the roll-type flexible circuit board extends through the outlet set on the outer surface of the cylinder shell, the hole wall of the outlet will rub against the circuit board, causing damage to the conductor on the surface of the circuit board, which is not conducive to subsequent use. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a roll-type flexible circuit board, which solves the problem that the conductors are easily damaged by friction with the inner wall of the outlet when the flexible circuit board is discharged from the outlet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roll-type flexible circuit board, comprising a housing, a rotating shaft rotatably connected to the inner side of the housing, a roll fixedly connected to the middle of the rotating shaft, a handwheel fixedly connected to one end of the rotating shaft, a flexible circuit board body wound on the roll, an outlet for discharging the flexible circuit board body opened on the outer side of the housing, a guiding mechanism provided on the inner side of the outlet, the guiding mechanism comprising two parallel guide rollers, both guide rollers being rotatably connected to the top end of the inner side of the outlet, two guide rollers being rotatably connected to the bottom end of the inner side of the outlet, a conveyor belt being provided between the two guide rollers, and the two guide rollers being drivenly connected by the conveyor belt, and a conveyor belt being provided between the two guide rollers, and the two guide rollers being drivenly connected by the conveyor belt, and a transmission component provided on one end of the inner side of the housing to drive the guide rollers to rotate in opposite directions or in opposite directions by cooperating with the rotation of the rotating shaft.

[0007] As a preferred embodiment of the present invention, the transmission component includes a gear one fixedly connected to one end of a rotating shaft, and one end of a guide roller two is fixedly connected to a gear two that meshes with the gear one.

[0008] As a preferred embodiment of the present invention, the transmission component further includes two gears, which are respectively fixedly connected to the ends of the corresponding guide rollers and guide rollers, and the two gears mesh with each other.

[0009] As a preferred embodiment of this utility model, gear one and gear two have the same number of teeth, and the two gear three have the same number of teeth.

[0010] As a preferred embodiment of this utility model, a limiting mechanism is provided on the outer side of the housing. The limiting mechanism includes a rotating seat fixedly connected to a rotating shaft. A plurality of limiting grooves are opened on the outer side of the rotating seat. The plurality of limiting grooves are distributed at equal angles around the rotating seat. A fixing plate is fixedly connected to the outer side of the housing. A limiting rod penetrating the fixing plate is slidably connected to one end of the fixing plate. The bottom end of the limiting rod is slidably engaged with any one of the limiting grooves. A pull block is fixedly connected to the top end of the limiting rod.

[0011] As a preferred embodiment of this utility model, a stop block is fixedly connected to the middle of the limiting rod, and a return spring is sleeved on the limiting rod. The top end of the return spring abuts against the fixed plate, and the bottom end of the return spring abuts against the stop block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the handwheel, the rotating shaft rotates, causing the drum to rotate and releasing the flexible circuit board body outward. The flexible circuit board body is then discharged from the discharge port, causing it to rub against the top surface of conveyor belt one and the bottom surface of conveyor belt two. When the rotating shaft rotates, the transmission component drives guide roller one and guide roller two to rotate in opposite directions, causing the top surface of conveyor belt one and the bottom surface of conveyor belt two to move in opposite directions. This ensures that the flexible circuit board body moves synchronously with the top surface of conveyor belt one and the bottom surface of conveyor belt two during the discharge process. This avoids the problem of conductor damage caused by friction between the flexible circuit board body and the top surface of conveyor belt one and the bottom surface of conveyor belt two.

[0019] 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.

[0020] like Figures 1 to 5As shown, this utility model provides a roll-type flexible circuit board, including a housing 1. A rotating shaft 2 is rotatably connected to the inner side of the housing 1. A roll 3 is fixedly connected to the middle of the rotating shaft 2. A handwheel 5 is fixedly connected to one end of the rotating shaft 2. A flexible circuit board body 4 is wound on the roll 3. A discharge port 7 for discharging the flexible circuit board body 4 is opened on the outer side of the housing 1. A guiding mechanism 8 is provided on the inner side of the discharge port 7. The guiding mechanism 8 includes two parallel guide rollers 81, both of which are rotatably connected to... At the top of the inner side of the discharge port 7, and at the bottom of the inner side of the discharge port 7, two guide rollers 82 are rotatably connected. A conveyor belt 83 is provided between the two guide rollers 81, and the two guide rollers 81 are connected by the conveyor belt 83. A conveyor belt 85 is provided between the two guide rollers 82, and the two guide rollers 82 are connected by the conveyor belt 85. At one end of the inner side of the housing 1, a transmission component 84 is provided to drive the guide rollers 81 and 82 to rotate in opposite directions or in opposite directions by cooperating with the rotation of the rotating shaft 2.

[0021] By rotating the handwheel 5, the shaft 2 rotates, causing the drum 3 to rotate and release the flexible circuit board body 4 outward. The flexible circuit board body 4 is then discharged from the discharge port 7, causing it to rub against the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85. When the shaft 2 rotates, the transmission component 84 drives guide roller 1 81 and guide roller 2 82 to rotate in opposite directions, causing the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85 to move in opposite directions. This ensures that the flexible circuit board body 4 moves synchronously with the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85 during the discharge process. This avoids the problem of conductor damage caused by friction between the flexible circuit board body 4 and the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85.

[0022] The transmission component 84 includes a gear 841 fixedly connected to one end of the rotating shaft 2, and a gear 842 that meshes with the gear 841 fixedly connected to one end of a guide roller 82. Both the guide roller 81 and the guide roller 82 at the same end are fixedly connected to a gear 843. The two gears 843 mesh with each other. The number of teeth of the gear 841 and the gear 842 are the same, and the number of teeth of the two gears 843 is the same.

[0023] By rotating the handwheel 5, the shaft 2 rotates, causing the drum 3 to rotate and release the flexible circuit board body 4 outward. The flexible circuit board body 4 is then discharged from the discharge port 7, causing it to rub against the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85. When the shaft 2 rotates, it drives gear 1 841 to rotate, causing gear 2 842 to rotate synchronously. This causes the two gears 3 843 to rotate in opposite directions, causing guide rollers 1 81 and 2 82 to rotate in opposite directions. Consequently, the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85 move in opposite directions. This ensures that the flexible circuit board body 4 moves synchronously with the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85 during the discharge process, thus preventing friction between the flexible circuit board body 4 and the top surface of conveyor belt 1 83 and the bottom surface of conveyor belt 2 85.

[0024] The outer side of the housing 1 is provided with a limiting mechanism 6. The limiting mechanism 6 includes a rotating seat 61 fixedly connected to the rotating shaft 2. The outer side of the rotating seat 61 is provided with several limiting grooves 62, which are distributed at equal angles around the rotating seat 61. A fixing plate 63 is fixedly connected to the outer side of the housing 1. A limiting rod 64 that passes through the fixing plate 63 is slidably connected to one end of the fixing plate 63. The bottom end of the limiting rod 64 is slidably engaged with any one of the limiting grooves 62. A pull block 65 is fixedly connected to the top end of the limiting rod 64. A stop block 66 is fixedly connected to the middle part of the limiting rod 64. A return spring 67 is sleeved on the limiting rod 64. The top end of the return spring 67 abuts against the fixing plate 63, and the bottom end of the return spring 67 abuts against the stop block 66.

[0025] When it is necessary to rotate the handwheel 5, the limit rod 64 is disengaged from the limit groove 62 by pulling the pull block 65 upward, which restricts the rotation seat 61 and allows the handwheel 5 to rotate. When it is not necessary to rotate the handwheel 5, the limit rod 64 is slidably engaged with the corresponding limit groove 6 by releasing the pull block 65, which restricts the rotation of the rotation seat 61 and thus restricts the rotation of the handwheel 5, thereby preventing the problem of the flexible circuit board body 4 being pushed out due to operator error.
