Description

Technical Field

[0001] This invention relates to the field of circuit board pressurization technology, and in particular to an adjustable pressurization device for flexible circuit board production. Background Technology

[0002] Flexible printed circuit boards (FPCs) are circuit boards made with flexible substrates. They possess high reliability and excellent flexibility, can be bent and folded, and can adapt to various shapes and sizes to meet design requirements, enabling complex circuit designs. They are lightweight, thin, and easy to use in confined spaces, offering good shock and impact resistance. Suitable for automotive, medical, and rail transportation industries, they offer low production costs, enabling mass production and rapid delivery. The manufacturing process of flexible printed circuit boards includes substrate selection, process preparation, circuit diagram transfer, copper foil etching, soldering, copper foil coating, adhesive bonding, copper plating of pads, surface protection, cutting, and finished product inspection. These steps ensure the high reliability and flexibility of flexible printed circuit boards. With the explosive growth of wearable devices, flexible displays, and smart devices, the demand for flexible printed circuit boards has increased significantly. The domestic flexible printed circuit board industry is also gradually entering a period of rapid growth, showing broad application prospects, especially in consumer electronics, automotive electronics, industrial control, medical equipment, and smart homes. Simultaneously, with continuous technological advancements, flexible printed circuit boards are gradually becoming a key technology for connecting electronic components. Flexible printed circuit boards, also known as "flexible boards," are printed circuits made with flexible insulating substrates, possessing many advantages that rigid printed circuit boards lack. It can be freely bent, rolled, and folded, and can be arranged arbitrarily according to spatial layout requirements. It can also move and stretch freely in three-dimensional space, thereby achieving the integration of component assembly and wire connection. Using FPC can greatly reduce the size of electronic products, which is suitable for the development of electronic products towards high density, miniaturization, and high reliability. Therefore, an adjustable pressure device for flexible circuit board production is needed in the process of flexible circuit board production.

[0003] Chinese patent document CN111970832B discloses an adjustable pressurizing device for flexible circuit board production. A hydraulic telescopic rod is fixedly connected to the middle of the upper surface of a supporting base plate, and a heating block is fixedly connected to the upper surface of the pressure plate. Through the coordinated arrangement of the hydraulic telescopic rod, pressure plate, placement platform, and heating block, during use, activating the hydraulic telescopic rod presses the pressure plate downwards, pressurizing the flexible circuit board. During pressurization, activating the heating block heats the pressurized flexible circuit board, resulting in a tighter fit and improved pressurization efficiency.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1-2As shown, an adjustable pressurizing device for flexible circuit board production includes a workbench 1. A hydraulic cylinder 2 is provided in the middle of the lower end of the workbench 1. The output end of the hydraulic cylinder 2 passes through the middle of the lower end of the workbench 1 and is fixedly connected to a pressurizing mechanism 8. A bearing mechanism 3 is symmetrically provided at the front and back of the upper end of the workbench 1. A connecting shaft 6 is provided between the opposite right sides of the two bearing mechanisms 3. A motor 5 is provided on the right side of the lower end of the workbench 1. A transmission wheel 7 is provided on the front side of the output end of the motor 5 and the outer surface of the connecting shaft 6. The two transmission wheels 7 are connected by a belt. A storage group 4 is provided at the right end of the workbench 1.

[0020] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 2 and motor 5 in this invention are all conventional designs and are standard design methods used by designers.

[0021] First, the entire device is supported by the workbench 1. Simultaneously, the hydraulic cylinder 2 and motor 5 are started, causing the motor 5 to drive the transmission wheel 7 and connecting shaft 6 to rotate via a belt. This, in turn, drives the symmetrical bearing mechanism 3 to operate. The hydraulic cylinder 2 drives the pressurizing mechanism 8 to pressurize the flexible circuit board in cooperation with the bearing mechanism 3. Furthermore, by adjusting the pressurizing mechanism 8, the pressure applied to the flexible circuit board can be changed according to processing needs, in cooperation with the hydraulic cylinder 2. At the same time, the pressurized flexible circuit board can be placed into the storage group 4 for cooling and storage through the pressurizing mechanism 8, eliminating the need for manual handling of the flexible circuit board after pressurization, thus improving the working efficiency of the device.

[0022] To allow for adjustments to the pressure applied to the flexible circuit board as needed, such as... Figure 3 As shown, the pressurizing mechanism 8 includes three auxiliary rods 81. The lower end of the middle auxiliary rod 81 is fixedly connected to the output end of the hydraulic cylinder 2, and the lower ends of the three auxiliary rods 81 all penetrate the middle of the upper end of the worktable 1. A cross pressure plate 82 is provided on the upper end of the three auxiliary rods 81. A motor 83 is provided in the middle of the upper end of the cross pressure plate 82. A groove is opened in the middle of the upper end of the cross pressure plate 82, and the motor 83 is installed in the inner cavity of the groove. Rotating screws 85 are provided on both the front and rear sides of the cross pressure plate 82. The rotating screw 85 has through holes on both sides, and can rotate through the rotating holes. The output end of the motor 83 and the upper end of the two rotating screws 85 are equipped with transmission wheels 84. The upper end of the rotating screw 85 on the rear side is composed of two transmission wheels 84. The upper one is connected to the transmission wheel 84 at the output end of the motor 83 via a belt, while the lower one is connected to the transmission wheel 84 at the upper end of the rotating screw 85 on the front side via a belt. The lower side of the outer surface of the two rotating screws 85 is equipped with pressing groups 86.

[0023] It should be noted that the specific installation method, circuit connection method, and control method of motor 283 in this invention are all conventional designs and are standard design methods used by designers.

[0024] When the hydraulic cylinder 2 is activated, the auxiliary rod 81 located in the middle drives the cross pressure plate 82, and with the cooperation of the rotating screw 85, the pressing groups 86 on both sides apply pressure to the flexible circuit board. If it is necessary to change the pressure, the motor 83 is activated. With the cooperation of the belt, the rotating screws 85 on both sides of the cross pressure plate 82 are rotated. The rotation of the rotating screws 85 on both sides drives the pressing group 86 to move vertically up and down to the appropriate position, changing the distance between the pressing group 86 and the cross pressure plate 82. Then the hydraulic cylinder 2 is activated again, so that the pressing group 86 applies pressure to the flexible circuit board, thereby changing the pressure.

[0025] To further explain, such as Figure 4 As shown, both pressing groups 86 include connecting seats 861 that mesh with the lower side of the outer surface of the rotating screw 85. Auxiliary rods 862 are symmetrically arranged on the upper horizontal sides of both connecting seats 861. The upper ends of the two auxiliary rods 862 on the same side penetrate from the lower end to the upper end of the cross pressure plate 82. Through holes are provided at corresponding vertical positions of the cross pressure plate 82 and the four auxiliary rods 862, and these through holes are adapted to the auxiliary rods 862. A pressure plate component 863 is provided at the lower end of both connecting seats 861. A retaining strip component 864 is provided at the ends of the two pressure plate components 863 that are far apart from each other. The retaining strip component 864 is fixedly connected to the pressure plate component 863 by bolts and can be disassembled as needed.

[0026] In detail, the connecting seat 861 is adapted to the rotating screw 85. When the rotating screw 85 rotates, the connecting seat 861 drives the pressure plate component 863 to move in the vertical direction through the cooperation of the auxiliary rod 862 and the through hole on the cross pressure plate 82, thereby changing the pressure intensity. The pressure plate component 863 includes a heating block. When the pressure plate component 863 applies pressure to the flexible circuit board, the flexible circuit board is heated, which makes the flexible circuit board fit more tightly, thereby improving the pressure efficiency of the device. The installed clip component 864 is used in conjunction with the bearing assembly 341 in the bearing mechanism 3.

[0027] Example 2: Based on Example 1, this example uses a pressurizing mechanism 8 to pressurize and automatically transport the flexible circuit board. Figure 4 As shown, both support mechanisms 3 include support plates 32 fixedly connected to the upper end of the worktable 1. Rollers 33 are provided on both the left and right sides of the two support plates 32. The outer surfaces of the two rollers 33 on the same side are connected to the conveyor belt 31. The upper end of the two support plates 32 is provided with a support component 34. The middle part of the opposite surface of the two rollers 33 on the right side is fixedly connected to the front and rear ends of the connecting shaft 6 respectively.

[0028] When the motor 5 is started, the two rollers 33 on the right side rotate on the support plates 32 on the same side in cooperation with the belt, connecting shaft 6 and transmission wheel 7, thereby causing the conveyor belt 31 to rotate. The pressure plate component 863 presses the flexible circuit board on the bearing component 34. After pressing, the bearing component 34 is adjusted in cooperation with the clip component 864, so that the flexible circuit board on the bearing component 34 slides onto the conveyor belt 31 and is then conveyed by the conveyor belt 31 to the storage group 4.

[0029] To further explain, such as Figure 6 As shown, both load-bearing components 34 include left and right symmetrical support frames 342. The upper side of the opposite surfaces of the two support frames 342 on the same side is provided with mounting grooves 343. The inner cavity of the two mounting grooves 343 on the same side is provided with a load-bearing assembly 341. The left and right sides of the load-bearing assembly 341 on the same side are provided with crank handles 344. A hole or groove adapted to the crank handle 344 is provided in the middle of the upper end of each support frame 342.

[0030] In detail, the support frame 342 is installed on the upper end of the support plate 32 without affecting the transport of the conveyor belt 31. The bearing assembly 341 is installed in the inner cavity of the mounting groove 343. The bearing assembly 341 is installed on the two support frames 342 on the same side by rotating the crank 344 through the crank 344. The bearing assembly 341 can be replaced according to the size of the flexible circuit board.

[0031] To further explain, such as Figure 7 and Figure 8 As shown, both load-bearing groups 341 include detachable plates 3411 that are slidably connected to the inner cavities of the two mounting slots 343 on the same side. The upper ends of the two detachable plates 3411 are provided with left and right symmetrical limiting holes 3412. The inner cavities of the two detachable plates 3411 are provided with several support groups 3413. The sides of the two detachable plates 3411 that are far apart from each other are provided with several fixing plates 3414. The lower middle part of the several fixing plates 3414 on the same side is provided with spring 3415. The lower right side of the several fixing plates 3414 on the same side is provided with support rod 3416.

[0032] In detail, the detachable plate 3411 is installed in the inner cavity of the mounting slot 343 by the crank handle 344 passing through the inner cavity of the limiting hole 3412, thus fixing the detachable plate 3411. The flexible circuit board is placed on several support groups 3413. The pressure plate component 863 applies pressure to the flexible circuit board at the upper end of the support group 3413. The pressure plate component 863 drives the locking strip component 864 to move downward. The support rod 3416, together with the fixing plate 3414, supports the support group 3413, so that the support group 3413 will not rotate during the pressure application process. After the pressure is applied, the pressure plate component 863 drives the locking strip component 864 to move upward. The locking strip component 864 drives the support group 3413 to pull the second spring 3415 to rotate. At this time, the flexible circuit board on the support group 3413 slides along the support group 3413 onto the conveyor belt 31. The detachable plate 3411 is equipped with a pressure sensor for detecting changes in pressure.

[0033] To further explain, such as Figure 9 As shown, each of the several support groups 3413 includes a support platform 34131 rotatably connected to the inner cavity of the detachable plate 3411. The end of each support platform 34131 near the fixed plate 3414 passes through the inner cavity of the detachable plate 3411 and is fixedly connected to a fixed box 34134. The upper right side of each fixed box 34134 is fixedly connected to the lower end of each spring 3415. The right wall of the inner cavity of each fixed box 34134 is provided with a spring 34133. The left end of each spring 34133 is provided with an arc-shaped slider 34132. The outer surface of each arc-shaped slider 34132 is slidably connected to the inner cavity of each fixed box 34134.

[0034] In detail, spring 2 3415 is fixedly connected to the upper right side of the fixed box 34134 at the same position. In the initial state, the support rod 3416 abuts against the upper right side of the fixed box 34134, and the support rod 3416 is located to the right of spring 2 3415. Then, the locking bar component 864 slides down to compress the arc-shaped slider 34132, so that when the arc-shaped slider 34132 compresses spring 1 34133 and enters the inner cavity of the fixed box 34134, it will not cause the support platform 34131 to rotate. And when the locking bar component 864 moves down to the appropriate position, spring 1 34133... Under the action of elastic force, the arc-shaped slider 34132 pops out and abuts against one side of the locking strip component 864. After the pressure plate component 863 presses the flexible circuit board on the support platform 34131, the locking strip component 864 moves upward, causing the arc-shaped slider 34132 and the fixing box 34134 to rotate, thereby causing the support platform 34131 to rotate to a suitable position. The flexible circuit board will slide down the support platform 34131 onto the conveyor belt 31 under the action of gravity. Several locking pins are installed on the locking strip component 864, and several locking pins are adapted to several arc-shaped sliders 34132.

[0035] To achieve cooling and storage of flexible circuit boards, such as Figure 10 As shown, the storage group 4 includes a connecting inclined plate 41 fixedly connected to the right end of the workbench 1. The right end of the connecting inclined plate 41 is provided with symmetrical air boxes 42. The upper left side of each of the two air boxes 42 is provided with a feed inlet 45. The lower side of the inner cavity of each of the two air boxes 42 is provided with a storage box 43. The top wall of the inner cavity of each of the two air boxes 42 is provided with a cold air component 44.

[0036] It should be noted that the cooling component 44 includes a ventilation plate and a cooler. The specific installation method, circuit connection method, and control method of the cooler are all conventional designs and are standard design methods used by designers. It is only necessary to satisfy the purpose of the cooler to cool the flexible circuit board through the ventilation plate.

[0037] As the flexible circuit board moves to the right along the conveyor belt 31, it enters the storage box 43 through the feed port 45 via the inclined plate installed on the connecting inclined plate 41. The flexible circuit board entering the air box 42 is cooled by the cold air component 44. When the storage box 43 is full of flexible circuit boards, the storage box 43 can be pulled out from the inner cavity of the air box 42, and the pressurized and cooled flexible circuit board can be taken out.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

When the locking component (864) slides down to compress the arc-shaped slider (34132), the arc-shaped slider (34132) compresses the spring (34133) and enters the inner cavity of the fixed box (34134). This will not cause the carrier platform (34131) to rotate. When the locking component (864) moves down to the appropriate position, the arc-shaped slider (34132) will pop out under the elastic force of the spring (34133) and press against one side of the locking component (864). After the pressure plate component (863) presses the flexible circuit board on the carrier platform (34131), the locking component (864) moves up to drive the arc-shaped slider (34132) and the fixed box (34134) to rotate, thereby driving the carrier platform (34131) to rotate to the appropriate position. The flexible circuit board will slide down the carrier platform (34131) onto the conveyor belt (31) under the action of gravity.
